    In early 1961 special representatives of the International Planned Parenthood Federation (IPPF) organized the Planned Parenthood Federation of Korea (PPFK). The leaders, mostly young university professors, physicians, and government officials well recognized in the fields of public health gynecology/obstetrics, pediatrics, nursing, sociology, social work, and economics, shared an interest in improving the national economy, the national welfare, countermeasures against the population crisis, and the urgent need for family planning services in Korea. The leadership of General Park Chung-hee led to adoption of a national policy in support of family planning at an early stage in November 1961. Since 1961, the government budget for family planning has doubled every year. The PPFK was asked to play a major role in planning, administration, training, information, and education of the national program until the government established the new section of Maternal and Child Health in the Ministry of Health and Social Affairs in 1963. The role of the PPFK has never diminished. The training of family planning personnel at various levels is still carried out entirely by the PPFK. The PPFK operates mobile vans to provide educational activities, IUD insertions, and male sterilization services to people in villages without doctors. The PPFK operates pilot projects to test new methods either in clinics or in the field. The PPFK exists to supplement and cooperate with the government in family planning. With its flexibility, the PPFK team of experts stands ready to provide quick and positive services without red tape.

    The Organization Department of the Haikou Municipal CCP Committee, the municipal grain, finance, commerce, education bureau, personnel, public security, labor, civil affairs, public health, and housing bureaus, supply and marketing cooperative, and planned parenthood office recently issued a joint circular on implementing the provincial planned parenthood regulations. The circular demanded that the marriage registration and census system be seriously implemented. When people are registering for marriage, we must teach them to have only 1 child. We must give priority in housing and employment to an only child and his parents. When commercial, supply, and marketing departments are distributing coupons for fuel, and nonstaple food, they should supply a double amount to the only child. We must carry out serious health care for an only child and give them regular physical check-ups. When they are ill, hospitals should give them priority in registration, treatment, reservation of beds and medicines. The circular reiterated: We must seriously implement the stipulations on rewards and punishments contained in the provincial planned parenthood regulations. Cadres, staff, or workers who apply to have only 1 child must be given lump sums in addition to enjoying the relevant rewards stipulated by the regulations. Cadres, staff, workers, inhabitants, and commune workers who depend on state grain who violate the regulations must be punished according to the regulation. As for those who have 3 or more than 3 children, a 2nd child without planning, or an illegitimate child, the child's grain ration will be sold at negotiated price up to the age of 14. The grain department will distribute to them a supply ticket for negotiated price grain to buy grain in assigned grain shops. full text

  3. Planned Parenthood of Southeastern Pennsylvania v. Casey.

    Science.gov (United States)

    1990-08-24

    Pennsylvania amended its abortion statute to include a mandatory 24-hour waiting period, parental consent, spousal notification, physician-only disclosure requirements, and various other reporting provisions. Planned Parenthood filed suit, alleging infringement of a woman's right to choose an abortion. The federal district court held the amendments to be unconstitutional. First, the 24-hour waiting period arbitrarily increased cost and risk of delay by requiring two trips to the abortion clinic, without furthering the state's interest in maternal health. Secondly, the amendment's requirement that only the physician, and not an agent, may disclose information relevant to informed consent unreasonably insisted that only a physician is competent to provide the information. The parental consent and spousal notification requirements imposed unconstitutional burdens on the woman's decision.

    We assessed the impact on depot medroxyprogesterone continuation when a large care provider was banned from a state-funded family planning program. We used three methods to assess the effect of the ban: (a) In a records review, we compared how many state program participants returned to two Planned Parenthood affiliates for a scheduled dose of depot medroxyprogesterone acetate (DMPA) immediately after the ban; (b) We conducted phone interviews with 224 former Planned Parenthood patients about DMPA use and access to contraception immediately after the ban; (c) We compared current contraceptive method of our interviewees to that of comparable DMPA users in the National Survey of Family Growth 2006-2010 (NSFG). (a) Fewer program clients returned for DMPA at a large urban Planned Parenthood, compared to a remotely located affiliate (14.4%, vs. 64.8%), reflecting different levels of access to alternative providers in the two cities. (b) Among program participants who went elsewhere for the injection, only 56.8% obtained it at no cost and on time. More than one in five women missed a dose because of barriers, most commonly due to difficulty finding a provider. (c) Compared to NSFG participants, our interviewees used less effective methods of contraception, even more than a year after the ban went into effect. Injectable contraception use was disrupted during the rollout of the state-funded family planning program. Women living in a remote area of Texas encountered more barriers. Requiring low-income family planning patients to switch healthcare providers has adverse consequences. Copyright © 2016 Elsevier Inc. All rights reserved.

    One of the variables that could explain the considerable variety of ways that adult couples handle the transition to parenthood is whether the pregnancy was planned or not. However, very little is known about the impact of pregnancy intendedness on the conjugal life of couples during this transition. The aim of this study was to address this gap…

    1989-02-07

    The Planned Parenthood League of Massachusetts instituted a class action suit challenging the constitutionality of a statute requiring minors seeking an abortion to obtain parental consent or to persuade a judge of their maturity to give informed consent or that abortion would be in their best interest. In order to invoke judicial review, the plaintiffs moved their suit to federal court. The District Court dismissed the case on grounds that federal review power would interfere with state administration. On appeal, the First Circuit Court of Appeals decided that the plaintiffs could proceed with their action. The Circuit Court found that federal adjudication would not unduly interfere with state administration and remanded the case for further proceedings. Although it affirmed the statute's validity, the circuit court ruled that the plaintiffs must be allowed the opportunity to demonstrate the statute's unconstitutionality.

    This edited collection shows that good parenthood is neither fixed nor stable. The contributors show how parenthood is equally done by men, women and children, in and through practices involving different normative guidelines. The book explores how normative layers of parenthood are constituted...... by notions such as good childhood, family ideals, national public health and educational strategies. The authors illustrate how different versions of parenthood coexist and how complex sets of actions are demanded to fulfil today’s expectations of parenthood in Western societies.

    1999-05-01

    For most of human existence and in most societies, women have been considered to be property and subject to men. Throughout history, with such notable exceptions as Queen Boadicea, Eleanor of Aquitaine, Elizabeth I of England, and Catherine the Great of Russia, women had little or no power until early in the 20th century when the women's suffrage movement was successful in the United States and in some European countries. As women have gained political rights, groups of women have sought sexual and reproductive rights, as exemplified by the feminist movement of the past few decades in the United States. Although marked strides toward achievement of reproductive choice have been taken in high-income countries, there remain major strictures to reproductive freedom for women in low-income countries. This area, which is replete with ethical and moral issues, has been addressed by the International Planned Parenthood Foundation (IPPF), which has worked to improve the sexual and reproductive health of women throughout the world. The IPPF Charter on Sexual and Reproductive Rights is a paradigm for both women's rights and human rights. Karen Newman is policy adviser with the IPPF and has codrafted the IPPF Charter on Sexual and Reproductive Rights together with two lawyers. She has held several positions within the IPPF, including medical researcher, press officer, and programme adviser in Europe, where she had responsibility for working with new family planning associations (FPAs) in the Czech Republic and Slovakia. At present, she is working to increase the capacity of IPPF member FPAs to undertake human rights-based advocacy for sexual and reproductive health and rights. Judith F. Helzner is director of Sexual and Reproductive Health at International Planned Parenthood Federation/Western Hemisphere Region, Inc., where she has worked since 1987. She holds M.A. degrees from the University of Pennsylvania in International Relations and Demography. Her previous employment

    Polivanova K.N

    2015-10-01

    Full Text Available The article presents an analysis of a number of publications which concern the modern socio-cultural situation and its consequences on contemporary parenthood. The constructs "parenthood" and "parenting" are presented:. the first one refers to a social role of an adult with a child in relation to other social roles and the latter with the process of child rearing. The major social trends are presented: Contemporary parenthood is analyzed and problematized due to the nature of modern challenges faced by educated parents. The following trends are discussed: erosion of understandable, clearly presented stereotypes and patterns of child rearing in the family, increase of variability of practices of child-parent interaction, growth of supply on the market of goods and services. All these major social trends bring to the sunset of "natural" parenthood and the decision to have a child turns to be a consciously planned strategy. The article shows that the appeal to expert knowledge in child rearing which is characteristic of postmodern era leads to new uncertainties due to the variety of inconsistent advice and expertise. Discussion of the transformations experienced by the family shows the transition from child-centered to adult-centered pattern. Thus, the conclusion is that contemporary parenting takes place against many (conscious and unconscious contradictions, particularly between the growing importance of the values of self-realization and commitment and the value of parenthood. This contradiction brings to stress and anxiety which in turn damages the perception of oneself as a parent. The growth of interest in the study of parental identity and self-efficacy is considered to be a promising direction of research

    2017-12-01

    We analyzed Twitter tweets and Twitter-provided user data to give geographical, temporal and content insight into the use of social media in the Planned Parenthood video controversy. We randomly sampled the full Twitter repository (also known as the Firehose) (n=30,000) for tweets containing the phrase "planned parenthood" as well as group-defining hashtags "#defundpp" and "#standwithpp." We used demographic content provided by the user and word analysis to generate charts, maps and timeline visualizations. Chi-square and t tests were used to compare differences in content, statistical references and dissemination strategies. From July 14, 2015, to January 30, 2016, 1,364,131 and 795,791 tweets contained "#defundpp" and "#standwithpp," respectively. Geographically, #defundpp and #standwithpp were disproportionally distributed to the US South and West, respectively. Word analysis found that early tweets predominantly used "sensational" words and that the proportion of "political" and "call to action" words increased over time. Scatterplots revealed that #standwithpp tweets were clustered and episodic compared to #defundpp. #standwithpp users were more likely to be female [odds ratio (OR) 2.2, confidence interval (CI) 2.0-2.4] and have fewer followers (median 544 vs. 1578, panalysis can be used to characterize and understand the content, tempo and location of abortion-related messages in today's public spheres. Further research may inform proabortion efforts in terms of how information can be more effectively conveyed to the public. This study has implications for how the medical community interfaces with the public with regards to abortion. It highlights how social media are actively exploited instruments for information and message dissemination. Researchers, providers and advocates should be monitoring social media and addressing the public through these modern channels. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Parenthood motives in IVF-mothers.

    Science.gov (United States)

    Colpin, H; De Munter, A; Vandemeulebroecke, L

    1998-03-01

    This is an exploratory study to answer two questions: (1) does in-vitro fertilization (IVF)-mothers' motivation for parenthood differ from the naturally conceiving mothers' motivation for parenthood? and (2) are IVF-mothers' parenthood motives correlated with their adjustment to parenthood (in the same way as they are for naturally conceiving mothers)? The study sample consisted of 31 mothers with a 24-30 month old, single-born child conceived by homologous IVF and a comparison group of 31 mothers with a naturally conceived child. Self-rating questionnaires were used. Overall, the parenthood motivation pattern was quite similar for IVF-mothers and mothers by natural conception. However, 'identity', 'motherhood' and 'social control' were significantly more important motives for IVF-mothers than for the naturally conceiving mothers. The two former motives remained more important for IVF-mothers when findings were adjusted for the influence of the mothers' age and educational level. Possible explanations for these findings refer to the infertility history. Overall, few correlations between parenthood motives and the adjustment to parenthood were significant, both for the IVF-mothers and for the mothers by natural conception. Further (hypothesis-testing) research is needed to support these findings.

  15. Oh baby! Motivation for healthy eating during parenthood transitions: a longitudinal examination with a theory of planned behavior perspective

    Science.gov (United States)

    2013-01-01

    Background Transitioning to parenthood is a major life event that may impact parents’ personal lifestyles, yet there is an absence of theory-based research examining the impact of parenthood on motives for dietary behaviour. As a result, we are unaware of the social cognitive variables that predict eating behaviour among those transitioning to parenthood. The purpose of the study was to examine eating behaviour motives across 12 months within the framework of the theory of planned behavior (TPB) and compare these across groups of new parents, non-parents, and established parents. Methods Non-parents (n = 92), new parents (n = 135), and established parents (n = 71) completed TPB questionnaires assessing attitudes, subjective norms, perceived behavioral control (PBC), and intentions and three day food records at baseline, and 6- and 12-months post-delivery (for parents) and 6- and 12-months post-baseline (for non-parents). Results Repeated measures ANOVAs revealed that among men, new- and established-parents had greater intentions to eat healthy compared to non-parents, F(2) = 3.59, p = .03. Among women, established parents had greater intentions than new- and non-parents, F(2) = 5.33, p = .01. Among both men and women during the first 6-months post-delivery, new-parents experienced decreased PBC, whereas established parents experienced increased PBC. Overall, affective attitudes were the strongest predictor of intentions for men (β = 0.55, p < .001) and women (β = 0.38, p < .01). PBC predicted changes in fruit and vegetable consumption for men (β = 0.45, p = .02), and changes in fat consumption for men (β = −0.25, p = .03) and women (β = −.24, p < .05), regardless of parent status. Conclusion The transition to parenthood for new and established parents may impact motivation for healthy eating, especially PBC within the framework of TPB. However, regardless of parental status, affective

    Purpose: Transgender individuals experience barriers to healthcare, including discrimination in care provision and lack of knowledge about transgender health. We assessed New York City (NYC) transgender and gender nonconforming individuals' sexual and reproductive health (SRH) needs, access to services, and interest in receiving services from Planned Parenthood of NYC (PPNYC). Methods: We conducted an anonymous Internet-based survey of transgender individuals residing in NYC from September to December 2014 by using snowball sampling. Results: Data were analyzed from 113 surveys. Although 74% (71/96) of respondents avoided or delayed healthcare in the past year, most respondents adhered to medically indicated SRH screenings. In the past year, 64% (45/70) and 67% (46/69) of respondents were tested for HIV and other sexually transmitted infections, respectively. In the past 3 years, 80% (39/49) of respondents received clinical breast/chest examinations and 83% (35/42) of eligible individuals received Pap tests. Respondents most often received care at LGBT specialty clinics (35% [37/105]) or at private doctors' offices (31% [32/105]). Eighteen percent (19/107) had ever been to a Planned Parenthood health center. On a four-point scale, respondents rated the following factors as most influential on whether they would seek care at PPNYC: assurance that staff received transsensitivity training (mean 3.8), the existence of gender identity nondiscrimination policies (mean 3.7), and the availability of transgender-specific services, such as hormone therapy (mean 3.7). Conclusions: Although the majority of transgender individuals in our sample received recommended SRH screenings, respondents reported barriers to accessing needed medical care. Healthcare organizations interested in better serving the transgender community should ensure a high level of training around transsensitivity and explore the provision of transgender-specific services.

  17. Brave and angry--the creation and development of the International Planned Parenthood Federation (IPPF).

    Claeys, Vicky

    2010-12-01

    This paper looks back on the developments in thinking from birth control, through voluntary family planning, to a comprehensive approach to sexual and reproductive health and rights (SRHR), and celebrates some of the key players in this evolution. It tells the story of the creation of the International Planned Parenthood Federation (IPPF) in 1952, and scrutinises how important this organisation was then and is now. It gives an idea of the efforts it took to reassemble initiatives around the world into one body, strong enough to foster the cause to the benefit of all. While IPPF was and still is a unique association, it has increased its partnerships and works together with a multitude of organisations active in the field of SRHR. In the current political context joint efforts are still needed to protect the universally recognised human right of people to decide freely and responsibly on the number and spacing of their children, and their access to adequate education and information.

    This paper reflects on how good parenthood is done through ‘we-ness’. We draw on empirical work published by Danish and Swedish researchers to argue that we-ness constitutes an ideal in contemporary family life. In our recent edited volume Doing good parenthood, we argue that the term parenthood...... and family life. With this paper, we explore and discuss the concepts of we-ness, childhood and parenthood further, foremost by analyzing how ideals of equality are translated into the everyday practices of doing we-ness and family life. How and by whom is we-ness established and are there intensive...... and light versions of we-ness? How can we understand the relation between we-ness and goodness in parenthood?...

    1987-01-01

    The health care profession is witnessing a shift in focus from the interests and needs of the service provider to those of the potential consumer in an effort to attract and maintain clients. This study illustrates the role that marketing research can play in the development of program strategies, even for relatively small organizations. The study was conducted for Planned Parenthood of Louisiana, a recently organized affiliate that began offering clinical services in May 1984, to provide information on the four Ps of marketing: product, price, place, and promotion. Data from telephone interviews among a random sample of 1,000 women 15-35 years old in New Orleans before the clinic opened confirmed that the need for family planning services was not entirely satisfied by existing service providers. Moreover, it indicated that clinic hours and the cost of services were in line with client interests. The most useful findings for developing the promotional strategy were the relatively low name recognition of Planned Parenthood and a higher-than-expected level of interest that young, low income blacks expressed in using the service.

    This study contributes to our knowledge on the association between parenthood and psychological well-being by examining whether pre-parenthood lifestyles (leisure and paid work) moderate the transition to parenthood. We expected that people with less active lifestyles would find it easier to adapt to the demands of parenthood. Using eleven waves of the Swiss Household Panel ( N  = 1332 men and 1272 women; 1999-2008, 2010), fixed effects models are estimated for men and women separately. Results show that-on average-parenthood was not associated with well-being for men, whereas it increased well-being for women. As expected, the well-being premium/cost to parenthood was contingent upon individuals' lifestyle before the transition to parenthood. For men, parenthood reduced well-being, but only if they frequently participated in leisure before the birth of the child. For women, motherhood had a beneficial effect on well-being but this effect was weaker for women who combined leisure with working long hours before motherhood.

  5. Parenthood by design.

    Science.gov (United States)

    Sleep, J

    1986-02-01

    Parenthood by design involves realistic preparation for practical aspects of parenting as well as the romantic illusions fostered by relatives, social pressure, and the media. The ideals do not mention the physical discomfort, exhaustion, jealousy, anger and frustration encountered in a normal puerperium. Many women have not returned to normal sexual activity, work and sports even by 6 weeks after delivery. Perineal discomfort is still experienced by 70% after 10 days, especially in cases of assisted vaginal delivery. Urinary incontinence is present in 20% up to 3 months after normal vaginal delivery. Many women report fatigue as the reason for not resuming sexual intercourse. Family interactions are stressed by the newcomer: rivalry on the part of the husband or siblings is common. Modern education in the attempt to train people for vocational competence has left out parenting. In England, midwives teach classes of 20 women for 5 contact hours in late pregnancy, and are expected to cover all aspects of pregnancy, labor, delivery, baby care, postnatal adjustment and support services. The schools have sex education, fostering freedom in life styles for young people, but little emphasis on responsibility. There are some community organizations such as the La Leche League, the National Childbirth Trust and the Meet-A-Mum Association that offer support during and after pregnancy. Accidental pregnancy with education as crisis intervention is inadequate for the future; parenthood by design would permit couples to experience parenthood as a period of growth based on a fuller understanding of practical reality.

  6. Why Parenthood, and Why Now?: Gay Men's Motivations for Pursuing Parenthood.

    Goldberg, Abbie E; Downing, Jordan B; Moyer, April M

    2012-02-01

    The current qualitative study of 35 pre-adoptive gay male couples (70 men) examined gay men's motivations to parent and their reasons for pursuing parenthood at the current time. Similar to heterosexual couples, gay men described a range of psychologically-oriented reasons as shaping their decision to become parents. Some of these (e.g., desire to teach a child tolerance) may have been uniquely shaped by their sexual minority status, and others (e.g., desire to give a child a good home) in part reflect their adoptive status. Men named age, finances, and relationship factors, as well as unique contextual factors such as the need to find and move to gay-friendly neighborhoods, as influencing their readiness to pursue parenthood at the current time. Gay men's motivations to parent echo normative life course decision-making processes, but also reflect concerns that are uniquely informed by their sexual minority status.

    Different reasons influence the current low birth-rate and the postponement of the birth of the first child throughout Europe. The aim of this study was to explore how highly educated women and men in Sweden reflect on fertility and postponed parenthood. We interviewed women (n = 22) and men (n = 18) who had started their professional careers and still had no children. Data were analysed with qualitative content analysis. Fertility was perceived as an unconsidered capacity, sometimes unpredictable, and different for women and men, but nevertheless taken for granted. The participants were of the opinion that fertility could be restored by assisted reproductive technologies or replaced by alternatives to a biological child. Postponed parenthood was described as an adaptation to societal changes and current discourses about parenthood as well as a consequence of a contemporary lifestyle with many competing priorities. Highly educated young women and men in contemporary Sweden have competing priorities when planning and setting goals for their lives, and having children is one of them. They describe fertility as an imperceptible and retrievable capacity and postponed parenthood as a rational adaptation to changes in society. These findings suggest that increased information about the limitations of human reproduction is needed, but also that societal support for younger parents is of utmost importance.

    The stress of pregnancy and parenthood during the intense educational experience of medical school could increase the risk of student burnout. Because 9.2 percent of U.S. medical students are parents by graduation, it would seem prudent to include this topic in wellness programs and policies. The purpose of this study was to determine the effects of pregnancy and parenthood on medical students. This was a cross-sectional, internet survey distributed to all four classes of medical students at the University of South Dakota Sanford School of Medicine during the 2016-2017 academic year. The survey determined self-reported pregnancy and parenthood information, knowledge of a medical school pregnancy policy, and policy recommendations. More than 85 percent of the 194 respondents recommended that the following elements be included in an institutional policy: process for arranging parental leave, how leave time might affect graduation, how missed requirements could be made up, and how to request special accommodation or leave. Twenty-nine of the respondents (15 percent) were parents or currently pregnant. Eight pregnancies during medical school were associated with complications, including three miscarriages. Of the 18 students who reported maternity or paternity leave, 13 (72 percent) and 10 (56 percent) would have extended their leave time if it did not delay graduation or only reduced their number of elective rotations, respectively. No student would choose to extend leave if it would delay graduation. This survey is the first of its kind investigating pregnancy and parenthood in medical students attending a U.S. medical school. Students want schools to provide clear, well-defined guidelines, scheduling flexibility and administrators who are approachable and understanding of their individual circumstances.

    Objectives We analyzed Twitter tweets and Twitter-provided user data to give geographical, temporal and content insight into the use of social media in the Planned Parenthood video controversy. Methodology We randomly sampled the full Twitter repository (also known as the Firehose) (n=30,000) for tweets containing the phrase “planned parenthood” as well as group-defining hashtags “#defundpp” and “#standwithpp.” We used demographic content provided by the user and word analysis to generate charts, maps and timeline visualizations. Chi-square and t tests were used to compare differences in content, statistical references and dissemination strategies. Results From July 14, 2015, to January 30, 2016, 1,364,131 and 795,791 tweets contained “#defundpp” and “#standwithpp,” respectively. Geographically, #defundpp and #standwithpp were disproportionally distributed to the US South and West, respectively. Word analysis found that early tweets predominantly used “sensational” words and that the proportion of “political” and “call to action” words increased over time. Scatterplots revealed that #standwithpp tweets were clustered and episodic compared to #defundpp. #standwithpp users were more likely to be female [odds ratio (OR) 2.2, confidence interval (CI) 2.0–2.4] and have fewer followers (median 544 vs. 1578, pSocial media analysis can be used to characterize and understand the content, tempo and location of abortion-related messages in today’s public spheres. Further research may inform proabortion efforts in terms of how information can be more effectively conveyed to the public. Implications This study has implications for how the medical community interfaces with the public with regards to abortion. It highlights how social media are actively exploited instruments for information and message dissemination. Researchers, providers and advocates should be monitoring social media and addressing the public through these modern channels

    In this study, we described and analyzed parents' experiences of teenage parenthood and the provision of support to their teenage children who had recently have become parents. A qualitative method was used. In-depth interviews with 24 participants were conducted, all parents of teenage parents. Data were analyzed using content analysis; four themes and 11 subthemes were identified. The results show that parents' norms and values were strongly influenced by their religious beliefs. The participants had mixed emotions and reactions to their teenage children's parenthood. Also participants were sources of support to the teenage parents and assisted them in their transition to parenthood. However, the participants also expressed the importance that their teenage children continue their education and avoid repeated pregnancies. This study highlights how emotional, instrumental, and informational support provided by parents to their teenagers can assist the latter in their transition to parenthood. In their work with teenage parents, healthcare providers can benefit from teenage parent's own parents involvement and experiences. © 2017 John Wiley & Sons Australia, Ltd.

    1986-02-01

    This study explores adolescent females' assessments of the rewards and costs of employment and parenthood, and the impact of these assessments on their plans for organizing their adult lives. 549 young women enrolled in the 11th and 12 grades at public schools in New York City completed questionnaires addressing their future work and fertility plans, characteristics of their present family life, and their assessments of how rewarding and costly the roles of employee and parent would be to them. Results suggest that daughters of homemakers and daughters of employed women differ in their assessment of each role, and take different factors into consideration when making these assessments. In evaluating work, daughters whose mothers are employed were likely to depend on their mothers' experiences for guidance. On the other hand, daughters whose mothers are homemakers have to go through a more elaborate process of deduction. They appear to assess whether their mothers are happy where they are now and then project whether another role would be more satisfying. These young women also tend to incorporate the opinion of the father more than do daughters of employed mothers. In evaluating the impact of children, the young woman's relation with her own mother is a critical factor affecting both group' assessments of the costs of children as well as the employed group's assessments of the rewards of children. Finally, the limitations of the sample should be kept in mind when discussing the results. Though the sample was large numerically, the overall response rate was low. In addition, the sample consisted of a large number of Catholic respondents.

    To investigate attitudes toward parenthood, long-term life satisfaction, and health and well-being in men diagnosed as infertile. A cross-sectional survey of a cohort of men 5 years after diagnosis of infertility. The andrology clinic at the Royal Women's Hospital Reproductive Services, Melbourne Australia. All men diagnosed at this center as infertile in 2001 and 2002. None. Attitudes to parenthood (Meaning of Parenthood), quality of intimate relationship (Intimate Bonds Measure), personality characteristics (Vulnerable Personality Style Questionnaire), life satisfaction (Satisfaction with Life Scale), and self-rated physical health (Physical Component Summary of SF-12 [PCS-12]) and relationship with mental health (Mental Component Summary of SF12 [MCS-12]). A total of 112 (41%) of 276 men completed the survey. Of these, 96% had pursued infertility treatment and 87% had become fathers. Only 10% thought that fertility confirmed by fatherhood reflected masculinity, and 84% desired parenthood as much as their partners did. When all other factors were controlled for, men who had not become fathers had poorer mental health (MCS-12 score = 43.9 +/- 9.9) than those who were fathers (MCS-12 score = 49.25 +/- 8.7). Clinical practice should not presume that infertile men conflate fertility and masculinity, are less distressed than women about the potential loss of parenthood, or adjust more readily to childlessness, which appear to be inaccurate but widespread stereotypes.

    Same-sex parenthood is controversial subject. In this paper, we provide insights into the attitudes and experiences of self-reported lesbians regarding parenthood or the prospect of becoming a parent in the current Greek social and cultural context. In Greece, lesbians are not allowed access to in vitro fertilisation (IVF), while a solitary ('single') woman is allowed access for medical reasons. Fifty-nine (59) semi-structured in-depth interviews were conducted with women. What emerged from our data was a clear trend for participants to wish to have their own biological children based mostly on the belief that pregnancy would lead to a sense of self-completeness and/or fulfilment. Women also reported the negative impact of prejudice and social oppression on their reproductive autonomy. Interviewees reported that their reproductive choices were negatively influenced by their family and the wider socio-cultural environment. Even within a semi-permissive legal framework, impaired social acceptance of lesbian parenthood prohibits lesbians from becoming mothers. A major reason responsible for the positive attitude of most participants to shared biological motherhood was an altruistic attitude towards their partners.

  2. Accounting for the money-made parenthood of transnational surrogacy.

    In the last decade, transnational surrogacy has attracted world-wide attention for making babies and pregnancies exchangeable with money. Involuntarily childless couples and individuals travel abroad and pay to have the desired child and to become parents. Acknowledging the importance of asking into the consequences of this monetization of reproduction, the author takes issue with universalistic assumptions about money and markets, and their presumed universal effects on social relations. Instead, it is argued that we need to explore how money works, and, by extension, how transnational surrogacy works out and becomes viable to people as a way to become parents. Putting together insights from economic sociology, and the assisted reproductive technology and parenting culture literature, the author employs the notion of accounting to grasp how people make sense of the money involved in making them parents. Based on a study involving 21 interviews with Norwegian gay and straight couples and single men and women seeking surrogacy abroad, the author explores how money is accounted for in three cases, set in three different countries; India, the United States and Canada. The analysis shows how money is accounted for in particular ways to confirm parenthood. These ways differ depending on the local context and transnational relations; ultimately making differentiated monetized parenthood. This is of significance when we try to conceptualize contemporary parenthood and how money seemingly sustains parenthood in ever more radical ways.

    Few programs exist to address Intimate Partner Violence (IPV) in Guinea. In 2014, Engender Health, in partnership with the local health authorities in Conakry, Guinea, piloted an integrated approach to IPV screening and counseling, within an existing family planning clinic. This article describes both the process of formulating and implementing this approach, as well as the results of an evaluation of the program. From January to June of 2014, Engender Health staff trained midwives at the Conakry International Planned Parenthood Federation family planning clinic staff in screening and counseling client for IPV. Program evaluators used project records, interview with program staff (n=3), midwives (n=3) and client exit interviews (n=53) to measure the outcomes of this pilot project. Regardless of their IPV status, clients appreciated having a venue in which to discuss IPV. Program staff also felt empowered by the additional training and support for IPV screening. The evaluation yielded valuable suggestions for improvement, including more time for staff training and mock client interview practice, additional skills in counseling, and stronger referral links for women who screen positive for IPV. Integrating IPV screening into family planning services is an important and feasible method for reaching vulnerable women with IPV services.

    The provision of family planning services has important health benefits for the U.S. Approximately 25 million women in the U.S. receive contraceptive services annually and 44 million make at least one family planning-related clinical visit each year. These services are provided by private clinicians, as well as publicly funded clinics, including specialty family planning clinics, health departments, Planned Parenthoods, community health centers, and primary care clinics. Recommendations for providing quality family planning services have been published by CDC and the Office of Population Affairs of the DHHS. This paper describes the process used to develop the women's clinical services portion of the new recommendations and the rationale underpinning them. The recommendations define family planning services as contraceptive care, pregnancy testing and counseling, achieving pregnancy, basic infertility care, sexually transmitted disease services, and preconception health. Because many women who seek family planning services have no other source of care, the recommendations also include additional screening services related to women's health, such as cervical cancer screening. These clinical guidelines are aimed at providing the highest-quality care and are designed to establish a national standard for family planning in the U.S. Published by Elsevier Inc.

    Full Text Available There is a general trend of postponing entry into parenthood in Europe, Scandinavia being no exception. Previous research has suggested a range of reasons for this pattern to emerge, but comparatively little attention has been given the possible impact of the social network on the decision to try for a child. This paper explicates ways in which young Swedish adults in focus group discussions reason about the impact of friends and family in their reproductive decision-making. The analysis is based on a discourse analytical approach and inspired by social influence theory. The result of the focus group data indicates that the desire to maintain belonging and rootedness to friends as well as to kin is influential in procreative decision-making. Friends and family are recurrently referred to in the participants’ reasoning about when parenthood is preferably entered.

    Objective We assessed the impact on depot medroxyprogesterone continuation when a large care provider was banned from a state-funded family planning program. Study Design We used three methods to assess the effect of the ban: (a) In a records review, we compared how many state program participants returned to two Planned Parenthood affiliates for a scheduled dose of depot medroxyprogesterone acetate (DMPA) immediately after the ban; (b) We conducted phone interviews with 224 former Planned Parenthood patients about DMPA use and access to contraception immediately after the ban; (c) We compared current contraceptive method of our interviewees to that of comparable DMPA users in the National Survey of Family Growth 2006–2010 (NSFG). Results (a) Fewer program clients returned for DMPA at a large urban Planned Parenthood, compared to a remotely located affiliate (14.4%, vs. 64.8%), reflecting different levels of access to alternative providers in the two cities. (b) Among program participants who went elsewhere for the injection, only 56.8% obtained it at no cost and on time. More than one in five women missed a dose because of barriers, most commonly due to difficulty finding a provider. (c) Compared to NSFG participants, our interviewees used less effective methods of contraception, even more than a year after the ban went into effect. Conclusions Injectable contraception use was disrupted during the rollout of the state-funded family planning program. Women living in a remote area of Texas encountered more barriers. Implications Requiring low-income family planning patients to switch healthcare providers has adverse consequences. PMID:26680757

    2007-12-01

    Full Text Available This article investigates the reproductive behavior of young women and men in the post-Soviet Central Asian republic of Kyrgyzstan, focusing on the link between migration and fertility. We employ event-history techniques to retrospective data from the 'Marriage, Fertility, and Migration' survey conducted in Northern Kyrgyzstan in 2005 to study patterns in first-time parenthood. We demonstrate the extent to which internal migration is related to family formation and to the patterns of becoming a parent after resettlement. We gain deeper insights into demographic behavior by considering information on factors such as the geographical destination of migration and retrospectively stated motives for reported moves. In addition, our study reveals clear ethno-cultural differences in the timing of entry into parenthood in Kyrgyzstan.

    2015-03-01

    Full Text Available Background The general objective of the project was to verify the role the partner’s empathy plays in the perceived adjustment to parenthood. Couple empathy and especially partner’s perspective-taking have been linked to better adaptation to parenthood, through increasing the quality of communication between parents or through reducing problems experienced during transition to parenthood. Empathy has been promoted among couples preparing for parenthood, for example during antenatal classes. Participants and procedure Two studies were conducted. The first study included 121 young mothers of children in their first year of life. They completed measures of adjustment to parenthood, postpartum depression, satisfaction with romantic relationship, and partner’s perceived empathy. In addition, women assessed factors associated with labour and midwife care. The second study involved 112 couples during transition to parenthood. Those couples were randomly assigned to experimental conditions using instructions in which they were asked to imagine a one’s own or b the partner’s situation after the child’s birth, and completed the questionnaire measuring expected adjustment to parenthood. Results Male perceived empathy, relational satisfaction and postpartum depression were predictors of adjustment to motherhood in Study 1. In addition, the more empathy females perceived in their partners, the lower was the level of postpartum depression they declared. Couples empathizing with the partner in Study 2 perceived the challenges of parenthood in a similar way. Future mothers perceived more parenthood problems only when assuming their own perspective. Conclusions The results of the studies indicate that empathy plays an important role in shaping adjustment to parenthood, especially motherhood. Low-dosage interventions might help couples to become aware of their mutual problems concerning transition to parenthood, when conducting longer programmes is

    To evaluate the percentage of couples achieving parenthood and the rate of separation 6 years after their first consultation for infertility. Epidemiological study in the reproductive medicine department of a French university hospital. All first consulting couples (FCC) who had their first infertility consultation in the department in 2007 were contacted by phone and asked to respond to a questionnaire concerning their infertility treatments, parenthood and marital status 6 years after their first consultation. Of the 685 FCC, 94 could not be contacted, 34 refused to respond and 557 (86%) answered the questionnaire. Of 557 FCC who have responded, 361 (65%) have achieved parenthood: 166 (46%) after treatment, 98 (27%) after spontaneous conception, 38 (11%) after both spontaneous and treatment-induced conception and 59 (16%) through adoption. Parenthood was not influenced either by the causes or duration of infertility. Separation occurred in 53 (9.5%) of FCC, mainly in those without any children (28% vs 4% in FCC with at least one child; P<.0001). Six years after their primary consultation, 25% of couples remained childless and 28% of them were separated. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  17. Parenthood, child-rearing and fertility in England, 1850-1914.

    Pooley, Siân

    2013-03-01

    Fertility declines across Europe and the Anglo-world have been explained as the result of reversals of intergenerational flows of wealth. According to this theory, the child was transformed from an economically-useful household asset to an emotionally-valued parental burden. This article is based on a comparative study of changing understandings of parenthood in three provincial English localities between 1850 and 1914. It works from the premise that in order to make sense of reproductive behaviour, it is essential to examine the meanings that men and women attached to childlessness, child-rearing and parenthood. It is argued that there was not a universal shift that made children into burdens. New understandings of the duties of parenthood did develop, but these were founded on class-, gender- and place-specific interpretations. These encouraged a minority of fathers and mothers to believe that together they had the capacity to improve the lives of their sons and daughters in pioneering ways. Given that husbands and wives had distinct motives for avoiding rearing many children and that the discussion of reproduction was shrouded in silence, the dissemination and use of new ideals of family was crucial in enabling birth control to be thought about respectably within marriage.

    Full Text Available The phenomenon of insufficient childbearing is a demographic and social problem of contemporary society. In order to resolve the determination of low fertility in Serbia at the end of the 20th century, empirical research of the effects of reproductive behavior had been intensified. The purpose of this paper is to point out to the characteristics of parenthood relevant for bringing the decision on giving birth to children on the basis of this empirical material. A comparative approach, based on illuminating the compatibility of practice and models of responsible parenthood, enables the recognition of limiting factors of childbearing not only of those who are already parents but of young people who still do not have this experience. The complexity and responsibility of the parent role are stressed as part of the experience as well as the basic characteristic of the parenthood model. An adequate and efficient rehabilitation of the role of parenthood, as a necessity of the pro-natal policy must take into consideration the gender asymmetry of parenthood into consideration as well.

  19. Tethered lives: A couple-based perspective on the consequences of parenthood for time use, occupation, and wages.

    Prior research on parenthood effects has typically used single-sex models and estimated average effects. By contrast, we estimate population-level variability in partners' changes in housework hours, paid work hours, occupation traits, and wages after becoming parents, and we explore whether one partner's adjustment offsets or supplements the other's. We find tradeoffs between spouses on paid work adjustments to parenthood, but complementarity in adjustments to housework hours, occupation traits, and wages. The effect of parenthood on wives' behaviors is larger and more variable than on husbands' behaviors in every domain. The modest variation between husbands in work responses to parenthood explains little of the variation in the motherhood penalty, while variation in wives' own behaviors plays a larger role. We refer to this pattern as tethered autonomy: variation across American couples in work responses to parenthood is shaped primarily by variation in wives' adjustments, while husbands' work acts largely as a fixed point.

  20. Parenthood and Life Satisfaction in Germany

    Full Text Available This article examines the association between parenthood and life satisfaction. It focuses on the question to which extent parental life satisfaction is influenced by individual and familial context. The empirical study is based on the data from the first wave of the German Family Panel (pairfam. All in all, the analyses show that although parents are less satisfied with their leisure time, their social contacts and their relationship, they are nonetheless more satisfied with their life in general than their childless peers. Increased life satisfaction is observed in particular in the first years following the birth of a child. The satisfaction of parents is, however, dependent upon different contextual factors. Parents in the medium and higher income ranges report a comparatively high degree of life satisfaction, whereas only a weak association is observed between parenthood and life satisfaction among low-income persons. Moreover, the life satisfaction of mothers, but not of fathers, varies with their employment status. For instance, only non-employed and part-time employed mothers report a greater life satisfaction than childless women. Finally, fathers whose family formation was presumably unplanned record no higher level of satisfaction than men without children.

    2016-08-01

    This article presents results of a qualitative study of 12 adult couples making transition to parenthood. The aim of the study was to research the meaning of transition to parenthood through the lens of transformative learning theory. Transformative learning theory explains learning through meaning-making of that life experience. In this paper, the spiritual dimension of learning is emphasized. An important part of research methodology included biographical method, using semi-structured interviews before and after the birth of the first child. The research showed that transformative learning occurs in different spheres of life during transition to parenthood. This paper discusses the spiritual dimension of learning, meaning-making and presents results of the research.

    The recent proliferation of studies examining cross-national variation in the association between parenthood and happiness reveal accumulating evidence of lower levels of happiness among parents than nonparents in most advanced industrialized societies. Conceptualizing parenting as a stressor buffered by institutional support, we hypothesize that parental status differences in happiness are smaller in countries providing more resources and support to families. Our analyses of the European Social Surveys (ESS) and International Social Survey Programme (ISSP) reveal considerable variation in the parenthood gap in happiness across countries, with the U.S. showing the largest disadvantage of parenthood. We also find that more generous family policies, particularly paid time off and childcare subsidies, are associated with smaller disparities in happiness between parents and non-parents. Moreover, the policies that augment parental happiness do not reduce the happiness of nonparents. Our results shed light on macro-level causes of emotional processes, with important implications for public policy.

    Directory of Open Access Journals (Sweden)

    Simone Perelson

    2006-09-01

    Full Text Available After situating homoparenthood within the context of the new social and medical practices concerning parenthood and reproduction, the article presents a scenario of the contemporary French debate on this issue. The thinking of five psychoanalysts on this matter will be broached : Joël Dor and his theory about the role of the function of the father and about the anatomic difference between sexes in the structure process of the subject; Pierre Legendre and his articulation between the fields of law and the psych in the involvement of the human being in the order of parenthood; Michel Tort and his criticism of the theories of that author; and Genevieve Delaisi de Parseval and her proposal of a broader definition of the family. And, finally, Sabine Prokhoris, and her distinction between “sexuation” and “difference of the sexes”. This presentation intends to dismantle the opposite arguments and demonstrates the legitimacy of the reasoning favorable to homosexual parenthood.

    This study aims to describe aspects of the scope and quality of family planning services provided by US publicly funded health centers before the release of relevant federal recommendations. Using nationally representative survey data (N=1615), we describe four aspects of service delivery: family planning services provided, contraceptive methods provided onsite, written contraceptive counseling protocols and youth-friendly services. We created a count index for each issue and used multivariable ordered logistic regression to identify health center characteristics associated with scoring higher on each. Half of the sample received Title X funding and about a third each were a community health center or health department clinic. The vast majority reported frequently providing contraceptive services (89%) and STD services (87%) for women in the past 3 months. Service provision to males was substantially lower except for STD screening. A total of 63% and 48% of health centers provided hormonal IUDs and implants onsite in the past 3 months, respectively. Forty percent of health centers included all five recommended contraceptive counseling practices in written protocols. Of youth-friendly services, active promotion of confidential services was among the most commonly reported (83%); offering weekend/evening hours was among the least (42%). In multivariable analyses, receiving Title X funding, having larger volumes of family planning clients and being a Planned Parenthood clinic were associated with higher scores on most indices. Many services were consistent with the recommendations for providing quality family planning services, but there was room for improvement across domains and health centers types. As assessed in this paper, the scope and quality of these family planning services was relatively high, particularly among Planned Parenthood clinics and Title X-funded centers. However, results point to important areas for improvement. Future studies should assess

    The present study discusses the impact of union and parenthood transitions on individuals' self-esteem and sense of mastery development from midadolescence to young adulthood by using multilevel analyses with longitudinal data of 7,339 individuals between ages 15 and 38. The results show that, first, individuals in marital unions show significantly greater rates of growth in self-esteem and sense of mastery, compared with singles. Therefore, entering into marriage provides greater protections to individuals' self-esteem and sense of mastery. Second, the transition to parenthood brings significant decreases in levels and increases in rates of change in self-esteem and sense of mastery among new parents. The degree of the aforementioned changes differs by new parents' gender, union status, and living arrangement with the child at childbirth. Women are influenced more negatively than men. Living with the child at childbirth reduces the degree of decreases in self-esteem and sense of mastery, especially for mothers. In sum, from midadolescence to young adulthood, the development of individuals' self-esteem and sense of mastery is shaped by their union and parenthood transitions. Moreover, the context where these transitions take place, including the type of union and the living arrangement, moderates the degree of the impact. Our findings have important implications for research and practice in promoting the family transition experience. (c) 2016 APA, all rights reserved).

    PrEP uptake has lagged among US women. PrEP stigma is a recognized barrier to uptake among MSM but remains largely unexplored among women. This study examined the pervasiveness of PrEP stigma among US women and its implications for uptake. Setting/Methods: In a 2017 online survey of Planned Parenthood patients drawn from the three cities with the highest numbers of new HIV infections in Connecticut, 597 heterosexually-active, HIV-negative, PrEP-inexperienced women reported background characteristics, two dimensions of anticipated PrEP stigma (PrEP-user stereotypes and PrEP disapproval by others), and three indicators of potential PrEP uptake (interest in learning more about PrEP, intention to use PrEP, and comfort discussing PrEP with a provider). Participants commonly perceived PrEP-user stereotypes, with many believing that others would regard them as promiscuous (37%), HIV-positive (32%), bad (14%), or gay (11%) if they used PrEP. Thirty percent would feel ashamed to disclose PrEP use. Many participants expected disapproval by family (36%), sex partners (34%), and friends (25%). In adjusted analyses, perception of PrEP-user stereotypes was uniquely associated with lower comfort discussing PrEP with a provider. Expected PrEP disapproval by others was uniquely associated with less PrEP interest, less intention to use PrEP, and less comfort discussing PrEP with a provider. Exploratory moderation analyses suggested intention to use PrEP was greatest when participants anticipated low levels of both PrEP-user stereotypes and PrEP disapproval by others. Findings highlight the need for positive messaging targeting potential PrEP users and their social networks to increase PrEP acceptance and uptake.

    Full Text Available In the world there are tendencies of early entering into sexual relations and simultaneous withdrawal of the age of marriage, an increase in the number of early pregnancies and abortions among minors. Existing programs for the prevention of risky sexual behavior are ineffective, since they are one-time, narrowly focused. The author presents the results of an experiment on the prevention of risky sexual behavior in adolescents based on the formation of their ideas of parenting and child-parent relations, and through the prism of this topic, allowing to build an image of reproductive behavior in the present and future. The program is designed taking into account the psychology of modern adolescents, in accordance with the principles of awareness and responsibility, is based on a restorative approach and resource approach to the formation of psychological readiness for parenthood M.E. Lantsburg. The program for the development of psychological preparedness for parenting in adolescents has two targets: the nearest: preventing adolescent pregnancy and reducing its negative consequences in the event of an early pregnancy, and strategic - preparing for the planning and birth of the coveted child in the future. The results prove that the adolescents' views about the family depend both on the experiences they experienced in their own childhood and on the trends in the social and political space discussed in this topic. The study showed that adolescents' views on sexual relations, family and parenthood can be purposefully influenced through a program based on the knowledge of age-related psychology, resource and recovery approaches and using interactive methods of teaching relevant to this age group.

Given that sexual minorities uniquely contend with sexual orientation-related stigma, this study examined how both internalized and enacted forms of stigma affect the mental health of lesbians and gay men during the transition to parenthood. In addition, the role of contextual support was examined. Higher perceived workplace support, family support, and relationship quality were related to lower depressive and anxious symptoms at the time of the adoption, and higher perceived friend support was related to lower anxiety symptoms. Lower internalized homophobia and higher perceived neighborhood gay-friendliness were related to lower depressive symptoms. Finally, individuals with high internalized homophobia who lived in states with unfavorable legal climates regarding gay adoption experienced the steepest increases in depressive and anxious symptoms. Findings have important implications for counselors working with sexual minorities, especially those experiencing the transition to parenthood.

    Full Text Available Standpoints on parenthood represent the central subject of sociological approach in analyzing social determination of low reproductive norms. The goal of comparative analysis (first research carried out at the end of the eighties, and the second at the end of the nineties in different political and socio-economic surroundings is to record changed arguments and to point out to possible consequences which could be manifested through changes of the prevailing type of parenthood, namely the future reproductive behavior of subpopulation of the young (secondary-school pupils and students. Argument change of parenthood motivation basis on the general level is manifested by the weakening of its instrumental foundation, due to the prevailing altruistic motive "children - the meaning of life". As regards birth control, the young are more willing to accept contemporary contraceptive methods. A stabilization of the average values of desired and expected number of children is noted, but this discord is still an indicator of the defeat of complete realization of the need for parenthood. The insisting on everyday life quality is still perceived as an inhabitation factor when bringing decision on the number of children. Changes in the standpoints concerning the relation between marriage and parenthood did not seriously shake up the traditional system of values, which points out to their mutual significant influence and connection. Changes in the standpoints resulted in slowing down the individualization of parenthood which is manifested through the decrease of stratum differences (towns and sex.

    2016-10-01

    Our prospective study investigated couples' expectations of adoptive parenthood and explored how these changed with their actual experience of parenthood. Six heterosexual couples were interviewed just before placement began and 6 months after the children had arrived. Interpretative Phenomenological Analysis (IPA) was used to analyse both sets of interview data. Expectations of adoptive parenthood mostly transformed smoothly into adoption experience for couples, but challenges were experienced when family scripts collided and a continued feeling of unsafe uncertainty then prevailed within these newly formed family systems. Family script collision seemed a particular problem for couples adopting sibling pairs. To further professional practice in working with families over the transition to adoptive parenting, we suggest that professionals keep in mind a framework that includes the following: Internal and external world influences on family members, Intergenerational issues, Family scripts and the Structural challenges of adoption (IIFS). © The Author(s) 2016.

    Full Text Available The role of both parents is essential in the proper development of the child’s personality. Closeness, warmth, directness and the intimacy of parents-children relationship, enable the proper formation of the child’s personality; an individual who is able to love and make warm and permanent contacts with other people. The family is the cradle of personality development of each child born to this world. It is on the basis of family that enables the child to form speech, language, emotions and attitudes towards the people closest to it and to the surrounding world. The family introduces the child to the world of culture and prepares him for participation in social life. Parenthood is of more importance in today's consciousness. Children are perceived not as “a gift from God”, but rather as “planned or expected children”. Responsible parenthood means acquiring the skills for the reorienting of the parents’ life, and the effort of self-control and to be on the alert in accompanying the child in his growing up. Active parental presence at every stage of the child’s development enables it to complete the required tasks and gain the upper level of maturity. Parents are obliged to do a lot more than just to welcome the child to this world. Mature parenthood demands patience, engagement and attention but most importantly immense love and devotion which are missing when it comes to contemporary parents “embedded” in “Fast culture”.

    2010-01-01

    On the basis of social structural theory and identity theory, the current study examined changes in gender-role attitudes and behavior across the first-time transition to parenthood and following the birth of a second child for experienced mothers and fathers. Data were analyzed from the ongoing longitudinal Wisconsin Study of Families and Work. Gender-role attitudes, work and family identity salience, and division of household labor were measured for 205 first-time and 198 experienced mothers and fathers across 4 time points from 5 months pregnant to 12 months postpartum. Multilevel latent growth curve analysis was used to analyze the data. In general, parents became more traditional in their gender-role attitudes and behavior following the birth of a child, women changed more than men, and first-time parents changed more than experienced parents. Findings suggest that changes in gender-role attitudes and behavior following the birth of a child may be attributed to both the process of transitioning to parenthood for the first time and that of negotiating the demands of having a new baby in the family.

  13. Family planning uses traditional theater in Mali.

    1988-01-01

    Mali's branch of the International Planned Parenthood Federation has found a vehicle that effectively conveys the idea of family planning through the use of contraception, a method that blends the country's cultural heritage and modern technology. Despite becoming the first sub-Saharan francophone country to promote family planning, Mali only counted 1% of its population using a modern method of contraception. So with the aid of The Johns Hopkins University/Population COmmunication Services (JHU/PCS), the Association Malienne pour la Protection et la Promotion de la Famille (AMPPF) developed several programs to promote contraception, but none were more successful than the Koteba Project, which used Mali's traditional theater form to communicate the message. While comical, the Koteba generally deals with social issues -- it informs and entertains. This particular Koteba told the story of two government employees, one with two wives and many children, the other with one wife and few children. The first one sees nothing but family problems: fighting wives and delinquent children. The second one, who had used family planning, enjoys a peaceful home. Upon hearing of his friend's successes with family planning, the tormented government employee becomes convinced of its needs, and persuades his wives to accompany him to a family planning clinic. Developed at a cost of approximately US $3000 and televised nationwide, the Koteba proved effective. A survey of 500 people attending an AMPPF clinic revealed that 1/4 of them remembered the program. With the success of the Koteba, JHU/PCS and AMPPF are now exploring other traditional channels of communication.

  14. Gender, Parenthood and Wage Differences: The Importance of Time-Consuming Job Characteristics.

    Using data from the Swedish Level of Living Survey (2000, 2010), we investigate how the gender wage gap varies with occupational prestige and family status and also examine the extent to which this gap is explained by time-consuming working conditions. In addition, we investigate whether there is an association between parenthood, job characteristics and wage (as differentiated by gender). The analyses indicate that there are gender differences regarding prestige-based pay-offs among parents that are partly explained by fathers' greater access to employment characterized by time-consuming conditions. Separate analyses for men and women demonstrate the presence of a marriage wage premium for both genders, although only men have a parenthood wage premium. This fatherhood premium is however only present in high-prestigious occupations. Compared with childless men, fathers are also more advantaged in terms of access to jobs with time-consuming working conditions, but the wage gap between fathers and childless men is not explained by differences in access to such working conditions.

    The emotional adjustment of couples undergoing assisted reproductive technology (ART) treatments has been widely studied; however, it remains unclear whether infertility history contributes to couples' adjustment. This study examined the impact of infertility history (duration of infertility and number of previous ART treatment cycles) on the emotional adjustment of couples undergoing an ART cycle and the mediating effect of importance of parenthood on that association. In this cross-sectional study, 70 infertile couples (70 women and 70 men) completed self-report questionnaires assessing emotional adjustment and infertility stress during the hormonal stimulation phase of an ART cycle. Path models accounting for the dyadic nature of the data examined the direct and indirect effects (by affecting representations about parenthood and childlessness) of infertility history on emotional adjustment. The number of previous cycles affected men's, but not women's, emotional adjustment by affecting the representations on the importance of parenthood and of childlessness. Duration of infertility had the opposite effect, as couples with longer infertility reported heightened importance of parenthood, which negatively affected their emotional adjustment. Infertility history was associated with emotional adjustment in men and women, although these associations were complex. The results suggest that progression through treatment is harder for those men and women who attribute higher importance to being parents, which is aggravated by longer infertility. What is already known about the subject? Infertility is an unexpected and stressful life event Assisted reproductive treatments (ART) are emotionally demanding What does this study add? The influence of infertility history on adjustment is mediated by the importance of parenthood Men and women are affected by their past history of infertility differently. © 2015 The Authors.

    2015-01-01

    Full Text Available In a comparative perspective, the paper shows students' attitudes towards family, marriage and parenthood obtained in an empirical study entitled 'Cultural orientation of actors/students, interethnic relations, national identity and the culture of peace in the Balkans' on the samples from the University of Bitola, Veliko Tarnovo and Niš. It analyzes findings from the three subsamples, and tests the hypothesis that students' religiousness and the firmness of their religious beliefs predicate their attitudes towards fami­ly, marriage and parenthood, irrespective of the country where they study. It is expected that the student youth in all subsamples shows preference for the individualistic model of partnership, symmetrical parenting, egalitarian partner and family relationships, but also that the choice of some attitudes clearly indicates the presence of traditional value patterns. At the same time, it is assumed that respondents who identify themselves as firm believ­ers, and those who express a lower level of religious tolerance towards other religions, largely follow traditional patterns in the notion of marriage, fami­ly and parenthood.

  1. Effects of single parenthood on educational aspiration and student disengagement in Korea

    Directory of Open Access Journals (Sweden)

    2008-05-01

    Full Text Available The recent rapid increase in divorce, along with its distinctive cultural and welfare environments for single-parent families, makes Korea an interesting case for examining effects of single parenthood on children's education. Using data from Korean 9th and 12th graders, I compare the levels of educational aspiration and student disengagement between students with two parents and those with a single parent, distinguishing divorced single fathers, widowed single fathers, divorced single mothers, and widowed single mothers. Logistic regression analyses show that students with a divorced single parent, regardless of gender of the parent, are much less likely to aspire to four-year university education and more likely to be disengaged than their counterparts with two parents. The effects of widowhood disappear once control variables are held constant. Lower household income among single-parent families explains in part the poorer educational outcomes of their children. Parent-child interaction is another important mediating factor for the effect of single fatherhood but not for single motherhood. The relevance of the extended family system and distinctive features of post-divorce living arrangements in Korea is discussed to understand the effects of single parenthood.

  2. "Unthinkable" parenthoods: homosexual, transvestite, and transsexual mothers and fathers

    Directory of Open Access Journals (Sweden)

    Elizabeth Zambrano

    Full Text Available The growing number of families formed by homosexual, transvestite, and transsexual fathers/mothers has not only become a social, but also socio-anthropological fact, requiring traditional convictions to be rethought. This paper aims at demonstrating how a traditional model of family - that is, a "normal" family - has been able to influence the construction of parenthoods considered, until recently, unthinkable, whether social or legally. I therefore believe that it is time to face new demands and deconstruct former certainties of Anthropology, Psychology and Psychoanalysis, and Law, so that these new families may find their place in society.

    Previous researchers have found evidence for differences in parenting goals between lesbian and gay people and their heterosexual peers. However, no previous research has quantified the parenting goals of bisexual people or evaluated parenting goals as a function of sexual partner gender. In addition, political and social climates for sexual minority people had improved rapidly since the last representative data on lesbian and gay peoples' plans for parenthood were collected. We analyzed data from 3,941 childless lesbian, gay, bisexual, and heterosexual participants from the 2011-2013 National Survey of Family Growth (NSFG; United States Department of Health and Human Services, Centers for Disease Control and Prevention, National Center for Health Statistics, 2014), a nationally representative sample of United States residents aged 15 to 44 years. We found that statistically significant, within-gender sexual orientation differences in parenting plans persist, despite social and legal changes. Consistent with hypotheses, bisexual men's parenting desires and intentions were similar to those of their heterosexual male peers and different from those of their gay male peers, while bisexual women's reports were more mixed. Also consistent with hypotheses, the gender of the most recent sexual partner was a strong predictor of parenting goals. We discuss implications for mental and reproductive health-care providers, attorneys, social workers, and others who interact with sexual minority adults.

    This article reviews the current research on the potential stressors associated with identity transformation experienced by same-sex couples during the transition to parenthood and the coping strategies they employ. By integrating disparate findings into an ecological, stress-strategy-adaptation framework, we demonstrate that the identity transformation experiences among same-sex couples during the transition to parenthood (a) involve various adaptive processes of navigating different stressors via their human agency within multiple nested contexts; (b) are products of the intersections of individual characteristics, relational dynamics, LGBT community culture, and heterosexual sociostructural norms; and (c) are complicated by social contextual factors such as social class, race/ethnicity, family structure, and the sociocultural environment associated with geographic location. Last, several avenues for future inquiry are suggested. PMID:27458482

    2016-04-01

    Full Text Available Transition to parenthood is a vulnerable period for spouses and can consequently lead to the disintegration of their relationship. The purpose of this research was to examine the experience of this transition, circumstances and risk factors for divorce from the perspective of divorcees in Slovenia who divorced in the first year of their child’s life. On the basis of semi -structured interviews with 15 divorcees, the findings of studies examining changes after the birth of a child were confirmed. The results pointed to risk factors for marriage, such as uncertain relationship between spouses prior to the childbirth, permeable boundaries in relations with families of origin, lack of practical and emotional support, and unreal expectations. The child’s arrival accentuates unsolved issues from the past and brings additional vulnerability to the relationship. The findings of this research are a contribution to the development of preventive, educative and therapeutic programmes for couples in transition to parenthood.

    Suicide attempters differ in the degree of planning for their suicide attempts. The purpose of this study was to identify differences between individuals who make planned (≥3 hours of planning) and unplanned (suicide attempts. Depressed suicide attempters (n = 110) were compared based on degree of planning of their most recent suicide attempt on demographic and clinical variables. Participants who made planned suicide attempts were more likely to have family history of completed suicide, more severe and frequent suicidal ideation, greater trait impulsivity, and greater suicidal intent and more severe medical consequences for both their most recent and most serious suicide attempts. These results suggest clear clinical differences based on the degree of suicide attempt planning. Severe suicidal ideation, high suicide intent, family history of suicide completion, and high levels of motor impulsivity contribute to a phenotype that is at greater risk of planned, highly lethal suicide attempts.

    Purpose: The purpose of this study was to determine the clinical effectiveness and dosimetric quality of fallback planning in relation to machine downtime. Methods: Plans for a Varian Novalis TX were mimicked, and fallback plans using an Elekta VersaHD machine were generated using a dual arc template. Plans for thirty (n=30) patients of various treatment sites optimized and calculated using RayStation treatment planning system. For each plan, a fall back plan was created and compared to the original plan. A dosimetric evaluation was conducted using the homogeneity index, conformity index, as well as DVH analysis to determine the quality of the fallback plan on a different treatment machine. Fallback plans were optimized for 60 iterations using the imported dose constraints from the original plan DVH to give fallback plans enough opportunity to achieve the dose objectives. Results: The average conformity index and homogeneity index for the NovalisTX plans were 0.76 and 10.3, respectively, while fallback plan values were 0.73 and 11.4. (Homogeneity =1 and conformity=0 for ideal plan) The values to various organs at risk were lower in the fallback plans as compared to the imported plans across most organs at risk. Isodose difference comparisons between plans were also compared and the average dose difference across all plans was 0.12%. Conclusion: The clinical impact of fallback planning is an important aspect to effective treatment of patients. With the complexity of LINACS increasing every year, an option to continue treating during machine downtime remains an essential tool in streamlined treatment execution. Fallback planning allows the clinic to continue to run efficiently should a treatment machine become offline due to maintenance or repair without degrading the quality of the plan all while reducing strain on members of the radiation oncology team.

  12. Gay fathers' motivations for and feelings about surrogacy as a path to parenthood.

    Why do gay men choose to start their families through surrogacy? Most fathers chose surrogacy because they considered adoption to be a less desirable and/or accessible path to parenthood. Little is known of gay fathers' motivations to use surrogacy as a path to parenthood over and above other forms of family building, such as adoption, and no studies have examined fathers' satisfaction with the surrogacy process. This study used a cross-sectional design as part of a larger investigation of parent-child relationships and child adjustment in 40 gay father surrogacy families. Multiple strategies (e.g. surrogacy agencies, social events and snowballing) were used to recruit as diverse a sample as possible. Data were obtained from 74 fathers (in 6 families only 1 father was available for interview). Semi-structured interviews, lasting ~1 h, were conducted in the family home (65%) or over Skype (35%) with 74 gay fathers (35 genetic fathers, 32 non-genetic fathers and 7 fathers who did not know or did not disclose who the genetic father was), when the children were 3-9 years old. Genetic and non-genetic fathers were just as likely to want to become parents and had similar motivations for choosing surrogacy as a path to parenthood. Most fathers (N = 55, 74%) were satisfied with surrogacy and were satisfied (N = 31. 42%) or had neutral feelings (N = 21, 28%) about their choice of who would be the genetic father. Most fathers received supportive reactions to their decision to use surrogacy from both families of origin (e.g. parents, siblings) (N = 47, 64%) and from friends (N = 63, 85%). Although diverse recruitment strategies were used, data were obtained from a volunteer sample. Therefore, the possibility that fathers who had a positive surrogacy experience may have been more likely to participate in the study, and therefore introduce bias, cannot be ruled out. Due to the high average annual income of the fathers in the study, findings may not generalize to gay fathers with

    Structured antenatal education programs for childbirth or parenthood, or both, are commonly recommended for pregnant women and their partners by healthcare professionals in many parts of the world. Such programs are usually offered to groups but may be offered to individuals. To assess the effects of this education on knowledge acquisition, anxiety, sense of control, pain, labour and birth support, breastfeeding, infant-care abilities, and psychological and social adjustment. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (April 2006), CINAHL (1982 to April 2006), ERIC (1984 to April 2006), EMBASE (1980 to April 2006) and PsycINFO (1988 to April 2006). We handsearched the Journal of Psychosomatic Research from 1956 to April 2006 and reviewed the reference lists of retrieved studies. Randomized controlled trials of any structured educational program provided during pregnancy by an educator to either parent that included information related to pregnancy, birth or parenthood. The educational interventions could have been provided on an individual or group basis. Educational interventions directed exclusively to either increasing breastfeeding success, knowledge of and coping skills concerning postpartum depression, improving maternal psycho-social health including anxiety, depression and self-esteem or reducing smoking were excluded. Both authors assessed trial quality and extracted data from published reports. Nine trials, involving 2284 women, were included. Thirty-seven studies were excluded. Educational interventions were the focus of eight of the studies (combined n = 1009). Details of the randomization procedure, allocation concealment, and/or participant accrual or loss for these trials were not reported. No consistent results were found. Sample sizes were very small to moderate, ranging from 10 to 318. No data were reported concerning anxiety, breastfeeding success, or general social support. Knowledge acquisition, sense of control

    Purpose: Adaptive radiation therapy for prostate cancer using online reoptimization provides an improved control of interfractional anatomy variations. However, the clinical implementation of online reoptimization is currently limited by the low efficiency of current strategies and the difficulties associated with integration into the current treatment planning system. This study investigates the strategies for performing fast (∼2 min) automatic online reoptimization with a clinical fluence-map-based treatment planning system; and explores the performance with different input parameters settings: dose-volume histogram (DVH) objective settings, starting stage, and iteration number (in the context of real time planning).Methods: Simulated treatments of 10 patients were reoptimized daily for the first week of treatment (5 fractions) using 12 different combinations of optimization strategies. Options for objective settings included guideline-based RTOG objectives, patient-specific objectives based on anatomy on the planning CT, and daily-CBCT anatomy-based objectives adapted from planning CT objectives. Options for starting stages involved starting reoptimization with and without the original plan's fluence map. Options for iteration numbers were 50 and 100. The adapted plans were then analyzed by statistical modeling, and compared both in terms of dosimetry and delivery efficiency.Results: All online reoptimized plans were finished within ∼2 min with excellent coverage and conformity to the daily target. The three input parameters, i.e., DVH objectives, starting stage, and iteration number, contributed to the outcome of optimization nearly independently. Patient-specific objectives generally provided better OAR sparing compared to guideline-based objectives. The benefit in high-dose sparing from incorporating daily anatomy into objective settings was positively correlated with the relative change in OAR volumes from planning CT to daily CBCT. The use of the

    2015-06-01

    Full Text Available Transition to parenthood represents an important life event increasing vulnerability to psychological disorders. Postpartum depression and parenting distress are the most common psychological disturbances and a growing scientific evidence suggests that both mothers and fathers are involved in this developmental crisis. This paper aims to explore maternal and paternal experience of transition to parenthood in terms of parenting distress and risk of postpartum depression. Seventy-five couples of first-time parents were invited to compile the Edinburgh Postnatal Depression Scale and the Parenting Stress Index-Short Form in the first month of children life. Study sample reported very high levels of parenting distress and a risk of postpartum depression in 20.8% of mothers and 5.7% of fathers. No significant correlation between parenting distress and the risk of postpartum depression emerged, both in mothers than in fathers group while maternal distress levels are related to paternal one. The first month after partum represents a critical phase of parents life and it could be considered a developmental crisis characterized by anxiety, stress and mood alterations that could have important repercussions on the child psycho-physical development.

    To synthesize the recent qualitative literature and identify the integrative themes describing the parenthood experiences of refugees, asylum-seekers and undocumented migrants. We searched seven online databases for the period January 2006 to February 2017. We included English and French published peer-reviewed articles and graduate-level dissertations, which qualitatively examined the parenthood experiences of refugees, asylum-seekers and undocumented migrants. We summarized study characteristics and performed a thematic analysis across the studies. One hundred thirty eight studies met inclusion criteria. All but three were conducted in high-income countries, mainly in the US. Migrants studied were mostly undocumented from Latin America and refugees from Sub-Saharan Africa. Almost all studies (93%) included mothers; about half (47%) included fathers; very few (5%) included extended family members. We identified three integrative themes: 1) experiencing hardship and/or loss in the context of precarious migration and past traumas; 2) building resilience and strength by bridging language, norms and expectations; and 3) living transnationally: obligations, challenges and resources. Each theme contributed to shaping the parenthood experience; the transnationalism theme intersected with the themes on hardship and loss and resilience and strength. More research is needed with fathers, extended family members, asylum-seekers and in the LMIC context. A transnational lens needs to be applied to programs, policies and future research for refugee, asylum-seeker and undocumented migrant parents. Addressing transnational concerns (family separation and reunification), acknowledging transnational resources, fostering a transnational family identity and conducting transnational and longitudinal studies are potentially pivotal approaches for this sub-population of parents.

    Parenthood has been associated with declines in leisure-time exercise and moderate-to-vigorous physical activity (MVPA), but less is known about its impact on sedentary time and light-intensity activity. Although the health benefits of MVPA are well established, a growing body of research has been showing that even after controlling for MVPA levels, a detrimental dose-response association exists between sedentary time and adverse health outcomes and a beneficial dose-response association exists for light-intensity activity. This study examined the impact of parenthood, the number of children in the home, and the age of the youngest child on objectively measured physical activity (i.e., accelerometer derived daily minutes of sedentary, light, and MVPA) among a nationally representative cross-sectional sample of 2234 men and women who participated in the 2009-2011 Canadian Health Measures Survey. After controlling for sociodemographic variables, ANCOVAs indicated that parents engaged in more light activity but less MVPA than non-parents and women whose youngest child was aged 12-15 years were more sedentary than women without children. Among both men and women, having a child activity and lowest MVPA. Modest differences emerged between the physical activity level of parents and non-parents for both genders and across intensity levels. In general, parenthood was associated with less MVPA and more light-intensity activity, and more differences emerged among women compared to men. More research is needed before conclusions can be drawn regarding the health consequences of these differences.

    2017-01-01

    This book addresses the most important aspects of how to plan and evaluate clinical trials with a composite primary endpoint to guarantee a clinically meaningful and valid interpretation of the results. Composite endpoints are often used as primary efficacy variables for clinical trials, particularly in the fields of oncology and cardiology. These endpoints combine several variables of interest within a single composite measure, and as a result, all variables that are of major clinical relevance can be considered in the primary analysis without the need to adjust for multiplicity. Moreover, composite endpoints are intended to increase the size of the expected effects thus making clinical trials more powerful. The book offers practical advice for statisticians and medical experts involved in the planning and analysis of clinical trials. For readers who are mainly interested in the application of the methods, all the approaches are illustrated with real-world clinical trial examples, and the software codes requ...

    New parents’ Facebook use was examined from a social capital perspective. Surveys regarding Facebook use and parenting satisfaction, parenting self-efficacy, and parenting stress were completed by 154 mothers and 150 fathers as part of a larger study of dual-earner, Mid-western U.S. couples making the transition to parenthood. Results indicated that mothers used Facebook more than fathers, and that mothers perceived an increase in use over the transition. When more of mothers’ Facebook friends were family members or relatives, and when fathers reported connecting with more of their Facebook friends outside of Facebook, they reported better parental adjustment. For mothers, however, more frequent visits to Facebook accounts and more frequent content management were each associated with higher levels of parenting stress. PMID:23671354

    This document contains provisions of the 1988 Queensland Australia Act prohibiting surrogate parenthood contracts. The Act defines "surrogate parent" and "prescribed contract" and prohibits the publication of any type of document which intends to induce a person to act as a surrogate parent, to seek such a person, or to state willingness to act as a surrogate. Offering to enter into a prescribed contract holds a penalty of 100 penalty units or three years' imprisonment or both. This Act applies if the offense occurs in Queensland or if the offender is normally a resident of Queensland, irrespective of where the offense occurs.

    We developed and evaluated a novel inverse optimization (IO) model to estimate objective function weights from clinical dose-volume histograms (DVHs). These weights were used to solve a treatment planning problem to generate ‘inverse plans’ that had similar DVHs to the original clinical DVHs. Our methodology was applied to 217 clinical head and neck cancer treatment plans that were previously delivered at Princess Margaret Cancer Centre in Canada. Inverse plan DVHs were compared to the clinical DVHs using objective function values, dose-volume differences, and frequency of clinical planning criteria satisfaction. Median differences between the clinical and inverse DVHs were within 1.1 Gy. For most structures, the difference in clinical planning criteria satisfaction between the clinical and inverse plans was at most 1.4%. For structures where the two plans differed by more than 1.4% in planning criteria satisfaction, the difference in average criterion violation was less than 0.5 Gy. Overall, the inverse plans were very similar to the clinical plans. Compared with a previous inverse optimization method from the literature, our new inverse plans typically satisfied the same or more clinical criteria, and had consistently lower fluence heterogeneity. Overall, this paper demonstrates that DVHs, which are essentially summary statistics, provide sufficient information to estimate objective function weights that result in high quality treatment plans. However, as with any summary statistic that compresses three-dimensional dose information, care must be taken to avoid generating plans with undesirable features such as hotspots; our computational results suggest that such undesirable spatial features were uncommon. Our IO-based approach can be integrated into the current clinical planning paradigm to better initialize the planning process and improve planning efficiency. It could also be embedded in a knowledge-based planning or adaptive radiation therapy framework to

    Full Text Available Abstract Background There are good opportunities in Sweden for health promotion targeting expectant parents and parents of young children, as almost all are reached by antenatal and child health care. In 2005, a multisectoral child health promotion programme (the Salut Programme was launched to further strengthen such efforts. Methods Between June and December 2010 twenty-four in-depth interviews were conducted separately with first-time mothers and fathers when their child had reached 18 months of age. The aim was to explore their experiences of health promotion and lifestyle change during pregnancy and early parenthood. Qualitative manifest and latent content analysis was applied. Results Parents reported undertaking lifestyle changes to secure the health of the fetus during pregnancy, and in early parenthood to create a health-promoting environment for the child. Both women and men portrayed themselves as highly receptive to health messages regarding the effect of their lifestyle on fetal health, and they frequently mentioned risks related to tobacco and alcohol, as well as toxins and infectious agents in specific foods. However, health promotion strategies in pregnancy and early parenthood did not seem to influence parents to make lifestyle change primarily to promote their own health; a healthy lifestyle was simply perceived as 'common knowledge'. Although trust in health care was generally high, both women and men described some resistance to what they saw as preaching, or very directive counselling about healthy living and the lack of a holistic approach from health care providers. They also reported insufficient engagement with fathers in antenatal care and child health care. Conclusion Perceptions about risks to the offspring's health appear to be the primary driving force for lifestyle change during pregnancy and early parenthood. However, as parents' motivation to prioritise their own health per se seems to be low during this period

    2018-01-29

    Referrals to other medical services are central to healthcare, including family planning service providers; however, little information exists on the nature of referral practices among health centers that offer family planning. We used a nationally representative survey of administrators from 1,615 publicly funded health centers that offered family planning in 2013-14 to describe the use of six referral practices. We focused on associations between various health center characteristics and frequent use of three active referral practices. In the prior 3 months, a majority of health centers (73%) frequently asked clients about referrals at clients' next visit. Under half (43%) reported frequently following up with referral sources to find out if their clients had been seen. A third (32%) of all health centers reported frequently using three active referral practices. In adjusted analysis, Planned Parenthood clinics (adjusted odds ratio 0.55) and hospital-based clinics (AOR 0.39) had lower odds of using the three active referral practices compared with health departments, and Title X funding status was not associated with the outcome. The outcome was positively associated with serving rural areas (AOR 1.39), having a larger client volume (AOR 3.16), being a part of an insurance network (AOR 1.42), and using electronic health records (AOR 1.62). Publicly funded family planning providers were heavily engaged in referrals. Specific referral practices varied widely and by type of care. More assessment of these and other aspects of referral systems and practices is needed to better characterize the quality of care.

  12. Intellectual Disability and Parenthood

    2005-01-01

    Full Text Available Parenthood in persons with intellectual disability (ID is an issue of concern for the family, guardians, and professionals as there are many sentiments and problems involved: financial, technical, medical, legal, and above all moral. People with intellectual, developmental, or other disabilities have feelings, want relationships, and are able to have children also. The attitude of society has changed through time from the early eugenic concern with heredity and fertility, to a focus on the risk to the children due to parental neglect or abuse, to acceptance and a search for solutions to parental training and support. This change can be seen as a result of a shift from institutional care to community care and normalization. This paper reviews available research, prevalence, service issues, experience from around the world, and relates to the situation in Israel. Jewish Law has been very progressive regarding the possibility of marriage between persons with ID (in contrast to American Law where historically this right has been denied, until recently. Recent research has shown that, in the case of such a union resulting in children, although they require some supervision, family, friends, and social welfare agencies have scrutinized these families so much they are in constant fear of their child being taken away. There is little information on the number of such cases and an overall dearth of information on the effects on the children, although one recent study from the U.K. has shown a varied picture of resilience and a close, warm relationship later on with the family and especially the mother.

  14. Love and Family: Discussions Between Swedish Men and Women Concerning the Transition to Parenthood

    Disa Bergnéhr

    2007-01-01

    Full Text Available This study is an exploration of how young Swedish adults talk about intimate relationships and the transition to parenthood. It is suggested that people carefully reflect over their relationship with their partner before deciding to embark on parenthood, and it is shown that reproductive decision making is imbued with contradictory ideals that may cause stress and anxiety. To have and to raise a child in a nuclear family arrangement is one prominent ideal that is illuminated by this study, but parallel with this is the notion of intimate relationships breaking down, dwindling. These two discourses are contradictory and create dilemmas in the process of family formation. Some individuals find the risk of relationship dissolution especially stressful, drawing on their own childhood experiences of growing up with separated parents. This is a study based on focus group interviews containing men and women, ranging from 24 to 39 years old, with different educational, occupational and geographical backgrounds; some are parents and some are not. The data are analysed using a discourse analytical approach, and much of the discussion is based on Anthony GIDDENS', Zygmunt BAUMAN's and Ulrich BECK and Elisabeth BECK-GERNSHEIM's reasoning about love and intimacy in the contemporary Western world.

    2014-01-01

    The purpose of this paper is to audit the active discharge (DC) planning process in a general cardiology clinic, by pre-assessing patients' medical notes and highlighting those suitable for potential DC to the clinic physician. The cardiology clinical nurse specialist (CNS) identified patients' for nine- to 12-month return visits one week prior to attendance. The previous consultation letter was accessed and information was documented by the CNS in the medical record. The key performance indicator (KPI) used was patient DCs for each clinic visit. The process was audited at three separate times to reflect recommended action carried out. The CNS pre-assessment and presence at the clinics significantly increased total DCs during the first period compared to usual care, 11 vs 34 per cent (p audit period, DCs fell (9 per cent) with a reduction in CNS pre-assessed DCs (10 per cent). Recommendations were implemented. The process was continued by clinic administration staff, colour coding all nine- to 12-month returns, resulted in a 19 per cent DC rate in 2012. CNS pre-assessment and highlighting DC suitability increased the number of patient DCs. As the CNS presence at the clinic reduced so did the rate of DC. Specific personnel need to be responsible for monitoring and reminding staff of the process; this does not always have to be medical or nursing. Implementing positive discharging procedures is aimed at improving quality, increasing efficiency and accessibility of services for patients. This audit describes a process to promote DC planning from cardiology outpatients.

    Full Text Available Psychological assessment has long been reported as a key component of clinical psychology. This paper examines the complexities surrounding the clinical significance of therapeutic approach to treatment planning. To achieve this objective, the paper searched and used the PsycINFO and PubMed databases and the reference sections of chapters and journal articles to analysed, 1 a strong basis for the usage of therapeutic approach to psychological assessment in treatment plans, 2 explained the conceptual meaning of clinical significant change in therapeutic assessment, 3 answered some of the questions regarding practicability and the clinical significance of therapeutic approach to treatment plans, particularly during or before treatment, 4 linked therapeutic assessment to change in clients’ clinical impression, functioning and therapeutic needs 5 analysed the empirically documenting clinically significant change in therapeutic assessment. Finally, the study suggested that though therapeutic assessment is not sufficient for the systematic study of psychotherapy outcome and process, it is still consistent with both the layman and professional expectations regarding treatment outcome and also provides a precise method for classifying clients as ‘changed’ or ‘unchanged’ on the basis of clinical significance criteria.

There are four viewpoints in surrogate parenthood rules, including the blood relationship theory, the uterus childbirth theory, contract doctrine and the theory of best interests for children. The attitudes to the surrogate parenthood rules vary from country to country. There are three kinds of attitudes including fully accredited surrogate attitude, completely prohibit surrogate and limited recognition. At present, the comprehensive prohibition of the surrogacy in our country is not fully adapted to the development of modern society. Surrogacy is necessary for legitimacy in china, but it can’ t be fully liberalized. It is possible to apply if it meets the conditions of finite application, subject qualification and non-commercializa-tion. Surrogate parenthood rules should keep to the blood relationship theory priority, both keep to the theory of best interests for children.

  1. Predictors of Parenting Stress in Lesbian, Gay, and Heterosexual Adoptive Parents During Early Parenthood

    2014-01-01

    Little work has examined parenting stress in adoptive parents, particularly lesbian and gay adoptive parents. The current longitudinal study examined parent-reported child characteristics (measured post-placement) and parent and family characteristics (measured pre-placement) as predictors of post-placement parenting stress and change in parenting stress across three time points during the first 2 years of adoptive parenthood, among 148 couples (50 lesbian, 40 gay, and 58 heterosexual) who were first-time parents. Children in the sample were, on average, 5.61 months (SD = 10.26) when placed, and 2.49 years (SD = .85) at the 2 year post-placement follow-up. Findings revealed that parents who had been placed with older children, and parents who perceived severe emotional/behavioral problems in their children, reported more post-placement stress. In addition, parents who reported fewer depressive symptoms, more love for their partners, and more family and friend support during the pre-placement period, had less post-placement stress. Parenting stress decreased for parents who perceived severe emotional/behavioral problems in their children, while it increased somewhat for those who reported developmental problems in their children. Findings highlight vulnerabilities and resources that may shape adoptive parents’ experiences of stress in early parenthood, and have implications for both researchers and professionals who wish to support adoptive family adjustment.

    2003-01-01

    Purpose: The main aim is to prove the clinical practicability of the hyperthermia treatment planning system HyperPlan on a β-test level. Data and observations obtained from clinical hyperthermia are compared with the numeric methods FE (finite element) and FDTD (finite difference time domain), respectively. Methods and Materials: The planning system HyperPlan is built on top of the modular, object-oriented platform for visualization and model generation AMIRA. This system already contains powerful algorithms for image processing, geometric modeling, and three-dimensional graphics display. A number of hyperthermia-specific modules are provided, enabling the creation of three-dimensional tetrahedral patient models suitable for treatment planning. Two numeric methods, FE and FDTD, are implemented in HyperPlan for solving Maxwell's equations. Both methods base their calculations on segmented (contour based) CT or MR image data. A tetrahedral grid is generated from the segmented tissue boundaries, consisting of approximately 80,000 tetrahedrons per patient. The FE method necessitates, primarily, this tetrahedral grid for the calculation of the E-field. The FDTD method, on the other hand, calculates the E-field on a cubical grid, but also requires a tetrahedral grid for correction at electrical interfaces. In both methods, temperature distributions are calculated on the tetrahedral grid by solving the bioheat transfer equation with the FE method. Segmentation, grid generation, E-field, and temperature calculation can be carried out in clinical practice at an acceptable time expenditure of about 1-2 days. Results: All 30 patients we analyzed with cervical, rectal, and prostate carcinoma exhibit a good correlation between the model calculations and the attained clinical data regarding acute toxicity (hot spots), prediction of easy-to-heat or difficult-to-heat patients, and the dependency on various other individual parameters. We could show sufficient agreement between

    2014-06-01

    Nepal has a distinct topography that makes reproductive health and family planning services difficult to access, particularly in remote mountain and hill regions where over a quarter of modern contraceptive users rely exclusively on vasectomy. A three-level random intercept logistic regression analysis was applied on data from the 2011 Nepal Demographic and Health Survey to investigate the extent of influence of mobile family planning clinics on the odds of a male or a female sterilization, adjusting for relevant characteristics including ecological differences and random effects. The analyses included a sample of 2014 sterilization users, considering responses from currently married women of reproductive ages. The odds of a male sterilization were significantly higher in a mobile clinic than those in a government hospital (odds ratio, 1.65; 95% confidence interval, 1.21-2.25). The effects remained unaltered and statistically significant after adjusting for sociodemographic and clustering effects. Random effects were highly significant, which suggest the extent of heterogeneity in vasectomy use at the community and district levels. The odds of vasectomy use in mobile clinics were significantly higher among couples residing in hill and mountain regions and among those with three or more sons or those with only daughters. Mobile clinics significantly increase the uptake of vasectomy in hard-to-reach areas of Nepal. Reproductive health interventions should consider mobile clinics as an effective strategy to improve access to male-based modern methods and enhance gender equity in family planning. Family planning interventions in hard-to-reach communities could consider mobile clinic as an effective strategy to promote male-based modern methods. Improving access to vasectomy could substantially reduce unmet need for family planning in countries experiencing rapid fertility transition. Copyright © 2014 Elsevier Inc. All rights reserved.

    Assisted reproduction technologies have developed at an extraordinary rate in recent years. This, combined with the changing landscape of legal, technical and social possibilities, enables gay men to consider their options for fatherhood as new opportunities emerge for them to create families. Media coverage of gay celebrities embracing surrogacy as a way of having a family and high-profile legal cases have raised awareness of surrogacy across the world. However, gay fatherhood achieved through assisted reproduction is a highly under-researched area, both in the UK and internationally. The research that currently exists on gay fatherhood is largely related to gay men who become parents through processes such as adoption and fostering and children conceived through previous heterosexual relationships. Much of this evidence has centred on parenting experiences, the outcomes for children or the legal perspectives. This paper outlines the different types of surrogacy and the legal issues facing gay men who choose this route to parenthood, summarizes the limited research on gay men and surrogacy and discusses gaps in the current knowledge base.

    Patient recruitment is widely recognized as a key determinant of success for clinical trials. Yet a substantial number of trials fail to reach recruitment goals-a situation that has important scientific, financial, ethical, and policy implications. Further, there are important effects on stakeholders who directly contribute to the trial including investigators, sponsors, and study participants. Despite efforts over multiple decades to identify and address barriers, recruitment challenges persist. To advance a more comprehensive approach to trial recruitment, the Clinical Trials Transformation Initiative (CTTI) convened a project team to examine the challenges and to issue actionable, evidence-based recommendations for improving recruitment planning that extend beyond common study-specific strategies. We describe our multi-stakeholder effort to develop a framework that delineates three areas essential to strategic recruitment planning efforts: (1) trial design and protocol development, (2) trial feasibility and site selection, and (3) communication. Our recommendations propose an upstream approach to recruitment planning that has the potential to produce greater impact and reduce downstream barriers. Additionally, we offer tools to help facilitate adoption of the recommendations. We hope that our framework and recommendations will serve as a guide for initial efforts in clinical trial recruitment planning irrespective of disease or intervention focus, provide a common basis for discussions in this area and generate targets for further analysis and continual improvement.

    1979-11-01

    44 participants from 12 West African nations met in Banjul, the Gambia, from October 22-26, 1979 and unanimously agreed that family planning is in conformity with Islam. They called for greater involvement of local Muslim leaders in African countries to encourage family planning for the promotion of maternal and child health. The Conference was sponsored by IPPF Africa Region and attended by representatives of Muslim associations, health and family planning workers, teachers, government officials, and experts on Muslim law from Cameroon, The Gambia, Ghana, Guinea, Liberia, Mali, Morocco, Nigeria, Senegal, Sierra Leone, Upper Volta, and Zaire. The Conference members acknowledged that while the Koran, the Sunna, and the concensus of most Islam scholars is that family planning is acceptable within marriage, most traditional religious leaders are ignorant of the fact. Muslim women should be encouraged to take an interest in family planning. Other recommendations were educating Muslims on nutrition, sanitation, and health; to collect views of African Muslim leaders and publicize them; and, to persuade Ministries of Education to include family relations and parenthood in school curricula.

For five prostate cases, sub-optimal treatment plans located at a clinical distance value of >0.32 (0.28–0.35 from fronts of Pareto optimal plans, were assessed to be of lower plan quality by our (12 observers (p < .05. In conclusion, the clinical distance measure can be used to determine if the difference between a front and a given plan (or between different fronts corresponds to a clinically significant plan quality difference.

Little is known about how family planning clinics implement brief IPV/RC assessment interventions in practice. We describe the uptake and impact of a brief, trauma-informed, universal IPV/RC assessment and education intervention. Intervention implementation was evaluated via a mixed methods study among women ages 18 and up receiving care at one of two family planning clinics in greater Baltimore, MD. This mixed methods study entailed a quasi-experimental, single group pretest-posttest study with family planning clinic patients (baseline and exit survey n = 132; 3-month retention n = 68; retention rate = 52%), coupled with qualitative interviews with providers and patients (total n = 35). Two thirds (65%) of women reported receiving at least one element of the intervention on their exit survey immediately following the clinic-visit. Patients reported that clinic-based IPV assessment is helpful, irrespective of IPV history. Relative to those who reported neither, participants who received either intervention element reported greater perceived caring from providers, confidence in provider response to abusive relationships, and knowledge of IPV-related resources at follow-up. Providers and patients alike described the educational card as a valuable tool. Participants described trade-offs of paper versus in-person, electronic medical record-facilitated screening, and patient reluctance to disclose current situations of abuse. In real-world family planning clinic settings, a brief assessment and support intervention was successful in communicating provider caring and increasing knowledge of violence-related resources, endpoints previously deemed valuable by IPV survivors. Results emphasize the merit of universal education in IPV/RC clinical interventions over seeking IPV disclosure.

    Nurses' clinical autonomy is considered important for patients' outcome and influenced by the implementation approach of innovations. Emergent change approach with participation in the implementation process is thought to increase clinical autonomy. Planned change approach without this participation is thought not to increase clinical autonomy. Evidence of these effects on clinical autonomy is however limited. To examine the changes in clinical autonomy and in personal norms and values for a planned change and emergent change implementation of an innovation, e.g. intensive insulin therapy. Prospective comparative study with two geographically separated nurses' teams on one intensive care unit (ICU), randomly assigned to the experimental conditions. Data were collected from March 2008 to January 2009. Pre-existing differences in perception of team and innovation characteristics were excluded using instruments based on the innovation contingency model. The Nursing Activity Scale was used to measure clinical autonomy. The Personal Values and Norms instrument was used to assess orientation towards nursing activities and the Team Learning Processes instrument to assess learning as a team. Pre-implementation the measurements did not differ. Post-implementation, clinical autonomy was increased in the emergent change team and decreased in the planned change team. The Personal Values and Norms instrument showed in the emergent change team a decreased hierarchic score and increased developmental and rational scores. In the planned change team the hierarchical and group scores were increased. Learning as a team did not differ between the teams. In both teams there was a change in clinical autonomy and orientation towards nursing activities, in line with the experimental conditions. Emergent change implementation resulted in more clinical autonomy than planned change implementation. If an innovation requires the nurses to make their own clinical decisions, an emergent change

    Full text: A multicentre planning study comparing intensity-modulated radiation therapy (IMRT) plans for the treatment of a head and neck cancer has been carried out. Three Australian radiotherapy centres, each with a different planning system, were supplied a fully contoured CT dataset and requested to generate an IMRT plan in accordance with the requirements of an IMRT-based radiation therapy oncology group clinical trial. Plan analysis was carried out using software developed specifically for reviewing multicentre clinical trial data. Two out of the three plans failed to meet the prescription requirements with one misinterpreting the prescription and the third failed to meet one of the constraints. Only one plan achieved all of the dose objectives for the critical structures and normal tissues. Although each centre used very similar planning parameters and beam arrangements the resulting plans were quite different. The subjective interpretation and application of the prescription and planning objectives emphasize one of the many difficulties in carrying out multicentre IMRT planning studies. The treatment prescription protocol in a clinical trial must be both lucid and unequivocally stated to avoid misinterpretation. Australian radiotherapy centres must show that they can produce a quality IMRT plan and that they can adhere to protocols for IMRT planning before using it in a clinical trial

    Older age is associated with an increased accumulation of multiple chronic conditions. The clinical management of patients suffering from multiple chronic conditions is very complex, disconnected and time-consuming with the traditional care settings. Integrated care is a means to address the growing demand for improved patient experience and health outcomes of multimorbid and long-term care patients. Care planning is a prevalent approach of integrated care, where the aim is to deliver more personalized and targeted care creating shared care plans by clearly articulating the role of each provider and patient in the care process. In this paper, we present a method and corresponding implementation of a semi-automatic care plan management tool, integrated with clinical decision support services which can seamlessly access and assess the electronic health records (EHRs) of the patient in comparison with evidence based clinical guidelines to suggest personalized recommendations for goals and interventions to be added to the individualized care plans.

    This study reviewed implementation of the Domestic Violence Routine Screening (DVRS) program at Family Planning NSW and outcomes of screening to determine the feasibility of routine screening in a family planning setting and the suitability of this program in the context of women's reproductive and sexual health. A retrospective review of medical records was undertaken of eligible women attending Family Planning NSW clinics between 1 January and 31 December 2015. Modified Poisson regression was used to estimate prevalence ratios and assess association between binary outcomes and client characteristics. Of 13440 eligible women, 5491 were screened (41%). Number of visits, clinic attended, age, employment status and disability were associated with completion of screening. In all, 220 women (4.0%) disclosed domestic violence. Factors associated with disclosure were clinic attended, age group, region of birth, employment status, education and disability. Women who disclosed domestic violence were more likely to have discussed issues related to sexually transmissible infections in their consultation. All women who disclosed were assessed for any safety concerns and offered a range of suitable referral options. Although routine screening may not be appropriate in all health settings, given associations between domestic violence and sexual and reproductive health, a DVRS program is considered appropriate in sexual and reproductive health clinics and appears to be feasible in a service such as Family Planning NSW. Consistent implementation of the program should continue at Family Planning NSW and be expanded to other family planning services in Australia to support identification and early intervention for women affected by domestic violence.

    To determine the quality of contraceptive services in family planning clinics in Lusaka, Zambia, using a standardized approach. We utilized the Quick Investigation of Quality, a cross-sectional survey tool consisting of a facility assessment, client-provider observation and client exit interview, in public-sector family planning clinics. Data were collected on availability of seven contraceptive methods, information given to clients, interpersonal relations between providers and clients, providers' technical competence and mechanisms for continuity and follow-up. Data were collected from five client-provider observations and client exit interviews in each of six public-sector family planning clinics. All clinics had at least two contraceptive methods continuously available for the preceding 6 months. Most providers asked clients about concerns with their contraceptive method (80%) and told clients when to return to the clinic (87%). Most clients reported that the provider advised what to do if a problem develops (93%), described possible side effects (89%), explained how to use the method effectively (85%) and told them when to come for follow-up (83%). Clients were satisfied with services received (93%). This application of the Quick Investigation of Quality showed that the participating family planning clinics in Lusaka, Zambia, were prepared to offer high-quality services with the available commodities and that clients were satisfied with the received services. Despite the subjective client satisfaction, quality improvement efforts are needed to increase contraceptive availability. Although clients perceived the quality of care received to be high, family planning service quality could be improved to continuously offer the full spectrum of contraceptive options. The Quick Investigation of Quality was easily implemented in Lusaka, Zambia, and this simple approach could be utilized in a variety of settings as a modality for quality improvement.

    We apply Sen's capability approach to evaluate the capabilities of Slovenian parents to reconcile paid work and family in the context of the transition to a market economy. We examine how different levels of capabilities together affect the work–life balance (WLB) of employed parents. We combine both quantitative and qualitative methodological approaches. The results of our quantitative and qualitative research show that increased precariousness of employment and intensification of work create gaps between the legal and normative possibilities for successful reconciliation strategies and actual use of such arrangements in Slovenia. The existing social policies and the acceptance of gender equality in the sphere of paid work enhance capabilities for reconciliation of paid work and parenthood, whereas the intensification of working lives, the dominance of paid work over other parts of life, and the acceptance of gender inequalities in parental and household responsibilities limit parents’ capabilities to achieve WLB.

    The transition to parenthood is a stressful period for most parents as individuals and as couples, with variability in parent mental health and couple relationship functioning linked to children's long-term emotional, mental health, and academic outcomes. Few couple-focused prevention programs targeting this period have been shown to be effective. The purpose of this study was to test the short-term efficacy of a brief, universal, transition-to-parenthood intervention (Family Foundations) and report the results of this randomized trial at 10 months postpartum. This was a randomized controlled trial; 399 couples expecting their first child were randomly assigned to intervention or control conditions after pretest. Intervention couples received a manualized nine-session (five prenatal and four postnatal classes) psychoeducational program delivered in small groups. Intent-to-treat analyses indicated that intervention couples demonstrated better posttest levels than control couples on more than two thirds of measures of coparenting, parent mental health, parenting, child adjustment, and family violence. Program effects on family violence were particularly large. Of eight outcome variables that did not demonstrate main effects, seven showed moderated intervention impact; such that, intervention couples at higher levels of risk during pregnancy showed better outcomes than control couples at similar levels of risk. These findings replicate a prior smaller study of Family Foundations, indicating that the Family Foundations approach to supporting couples making the transition to parenthood can have broad impact for parents, family relationships, and children's adjustment. Program effects are consistent and benefit all families, with particularly notable effects for families at elevated prenatal risk.

    Purpose: To prospectively compare plans generated with iCycle, an in-house-developed algorithm for fully automated multicriterial intensity modulated radiation therapy (IMRT) beam profile and beam orientation optimization, with plans manually generated by dosimetrists using the clinical treatment planning system. Methods and Materials: For 20 randomly selected head-and-neck cancer patients with various tumor locations (of whom 13 received sequential boost treatments), we offered the treating physician the choice between an automatically generated iCycle plan and a manually optimized plan using standard clinical procedures. Although iCycle used a fixed “wish list” with hard constraints and prioritized objectives, the dosimetrists manually selected the beam configuration and fine tuned the constraints and objectives for each IMRT plan. Dosimetrists were not informed in advance whether a competing iCycle plan was made. The 2 plans were simultaneously presented to the physician, who then selected the plan to be used for treatment. For the patient group, differences in planning target volume coverage and sparing of critical tissues were quantified. Results: In 32 of 33 plan comparisons, the physician selected the iCycle plan for treatment. This highly consistent preference for the automatically generated plans was mainly caused by the improved sparing for the large majority of critical structures. With iCycle, the normal tissue complication probabilities for the parotid and submandibular glands were reduced by 2.4% ± 4.9% (maximum, 18.5%, P=.001) and 6.5% ± 8.3% (maximum, 27%, P=.005), respectively. The reduction in the mean oral cavity dose was 2.8 ± 2.8 Gy (maximum, 8.1 Gy, P=.005). For the swallowing muscles, the esophagus and larynx, the mean dose reduction was 3.3 ± 1.1 Gy (maximum, 9.2 Gy, P<.001). For 15 of the 20 patients, target coverage was also improved. Conclusions: In 97% of cases, automatically generated plans were selected for treatment because of

    Purpose: To demonstrate the clinical feasibility and potential benefits of sector beam intensity modulation (SBIM) specific to Gamma Knife stereotactic radiosurgery (GKSRS). Methods and Materials: SBIM is based on modulating the confocal beam intensities from individual sectors surrounding an isocenter in a nearly 2π geometry. This is in contrast to conventional GKSRS delivery, in which the beam intensities from each sector are restricted to be either 0% or 100% and must be identical for any given isocenter. We developed a SBIM solution based on available clinical planning tools, and we tested it on a cohort of 12 clinical cases as a proof of concept study. The SBIM treatment plans were compared with the original clinically delivered treatment plans to determine dosimetric differences. The goal was to investigate whether SBIM would improve the dose conformity for these treatment plans without prohibitively lengthening the treatment time. Results: A SBIM technique was developed. On average, SBIM improved the Paddick conformity index (PCI) versus the clinically delivered plans (clinical plan PCI = 0.68 ± 0.11 vs SBIM plan PCI = 0.74 ± 0.10, P=.002; 2-tailed paired t test). The SBIM plans also resulted in nearly identical target volume coverage (mean, 97 ± 2%), total beam-on times (clinical plan 58.4 ± 38.9 minutes vs SBIM 63.5 ± 44.7 minutes, P=.057), and gradient indices (clinical plan 3.03 ± 0.27 vs SBIM 3.06 ± 0.29, P=.44) versus the original clinical plans. Conclusion: The SBIM method is clinically feasible with potential dosimetric gains when compared with conventional GKSRS

  18. Birth control, population control, and family planning: an overview.

    This overview of the US birth control movement reflects on the emergence of family planning policy due to the efforts of Margaret Sanger, feminists, and the civil rights movement, the eugenics motive to limit "deviant" populations, and the population control movement, which aims to solve social and economic problems through fertility control. Population control moved through three stages: from the cause of "voluntary motherhood" to advance suffrage and women's political and social status, to the concept of "birth control" promoted by socialist feminists to help empower women and the working class, to, from 1920 on, a liberal movement for civil rights and population control. Physicians such as Dr. Robert Latou Dickinson legitimized the movement in the formation of the Committee on Maternal Health in 1925, but the movement remained divided until 1939, when Sanger's group merged with the American Birth Control League, the predecessor of the present Planned Parenthood Federation of America. A key legal decision in 1939 in the United States v. One Package amended the Comstock Act and allowed for the distribution of birth control devices by mail to physicians. Sanger, after a brief retirement, formed the International Planned Parenthood Federation and supported research into the pill. Eugenicists through the Committee on Maternal Health supported Christopher Tietze and others developing the pill. Final constitutional access to contraception based on the right to privacy was granted in Griswold v. Connecticut. The ruling in Eisenstadt v. Baird in 1972 extended this right to unmarried persons. The right to privacy was further extended in the Roe v. Wade decision in 1973 on legal abortion. The argument for improving the quality of the population remained from the formation of the Population Reference Bureau in 1929 through the 1960s. Under the leadership of Rockefeller, population control was defined as justified on a scientific and humanitarian basis. US government support

    Cancer does not occur in all ethnic and racial groups at similar rates. In addition, responses to treatment also vary in certain ethnic and racial groups. For Hispanics, the overall cancer incidence is generally lower yet for some specific tumor types, the incidence rates are higher compared to other populations. Although disparities are recognized for treatment outcomes and prevention methodologies for Hispanics and other minority populations, specific recruiting and reporting of minorities remains a challenge. In order to circumvent this problem, the Cancer Therapy and Research Center (CTRC) has developed a new minority recruitment plan for all cancer related clinical trials at this Institute. The overall goal of this initiative is to increase the accrual of minorities in cancer clinical trials by implementing several key interventions. The Cancer Therapy & Research Center (CTRC) at the University of Texas Health Science Center at San Antonio established the Clinical Trials Accrual Task Force to develop and monitor interventions designed to increase accrual to cancer clinical trials, specifically the accrual of minorities with a focus on the Hispanic population that makes up 68% of the CTRC's catchment area. A Minority Accrual Plan (MAP) was implemented in March 2013 as part of the process for initiating and conducting cancer-related clinical trials at the CTRC. The Minority Accrual Plan focuses on Hispanic enrollment due to the characteristics of the South Texas population served by the CTRC but could be easily adapted to other populations. The CTRC has designed a process to prospectively address the challenge of deliberately enrolling minority subjects and accurately accounting for the results by implementing a Minority Accrual Plan for every cancer-related clinical trial at CTRC.

    Experienced discrimination refers to an individual's perception that they have been treated unfairly due to an attribute and is an important recent focus within stigma research. A significant proportion of mental health service users report experiencing mental illness-based discrimination in relation to parenthood. Existing studies in this area have not gone beyond prevalence, therefore little is known about the nature of experienced discrimination in relation to parenthood, and how is it constituted. This study aims to generate a typology of community psychiatric service users' reports of mental illness-based discrimination in relation to becoming or being a parent. A secondary aim is to assess the prevalence of these types of experienced discrimination. In a telephone survey 2026 community psychiatric service users in ten UK Mental Health service provider organisations (Trusts) were asked about discrimination experienced in the previous 12 months using the Discrimination and Stigma Scale (DISC). The sample were asked if, due to their mental health problem, they had been treated unfairly in starting a family, or in their role as a parent, and gave examples of this. Prevalence is reported and the examples of experienced discrimination in relation to parenthood were analysed using the framework method of qualitative analysis. Three hundred and four participants (73% female) reported experienced discrimination, with prevalences of 22.5% and 28.3% for starting a family and for the parenting role respectively. Participants gave 89 examples of discrimination about starting a family and 228 about parenting, and these occurred in social and professional contexts. Ten themes were identified. These related to being seen as an unfit parent; people not being understanding; being stopped from having children; not being allowed to see their children; not getting the support needed; children being affected; children avoiding their parents; children's difficulties being blamed

    Purpose: Plan degradation resulting from compromises made to enhance delivery efficiency is an important consideration for intensity modulated radiation therapy (IMRT) treatment plans. IMRT optimization and/or multileaf collimator (MLC) sequencing schemes can be modified to generate more efficient treatment delivery, but the effect those modifications have on plan quality is often difficult to quantify. In this work, the authors present a method for quantitative assessment of overall plan quality degradation due to tradeoffs between delivery efficiency and treatment plan quality, illustrated using comparisons between plans developed allowing different numbers of intensity levels in IMRT optimization and/or MLC sequencing for static segmental MLC IMRT plans. Methods: A plan quality degradation method to evaluate delivery efficiency and plan quality tradeoffs was developed and used to assess planning for 14 prostate and 12 head and neck patients treated with static IMRT. Plan quality was evaluated using a physician's predetermined “quality degradation” factors for relevant clinical plan metrics associated with the plan optimization strategy. Delivery efficiency and plan quality were assessed for a range of optimization and sequencing limitations. The “optimal” (baseline) plan for each case was derived using a clinical cost function with an unlimited number of intensity levels. These plans were sequenced with a clinical MLC leaf sequencer which uses >100 segments, assuring delivered intensities to be within 1% of the optimized intensity pattern. Each patient's optimal plan was also sequenced limiting the number of intensity levels (20, 10, and 5), and then separately optimized with these same numbers of intensity levels. Delivery time was measured for all plans, and direct evaluation of the tradeoffs between delivery time and plan degradation was performed. Results: When considering tradeoffs, the optimal number of intensity levels depends on the treatment

    Full Text Available The literature on the division of domestic work has revealed the influence of the life cycle on family organization. Concretely, the arrival of children seems to have a signifi cant impact on the division of domestic tasks. This article looks at the effect of parenthood in the Spanish case, examining whether couples with children have a more traditional division of work than couples without children, and if so, in what way, and whether there have been changes in this trend over time. For this purpose, we follow the the empirical strategy of Dribe and Stanfors (2009 for the Swedish case, analyzing the time devoted to different activities using data from time use surveys from 2002-2003 and 2009-2010. The results show that couples with children have a more traditional division of labor than couples without children, and that it is also affected by the age of the children. In addition, our fi ndings show this trend was less pronounced in 2009-10.

    Purpose: A prototype of the hyperthermia treatment planning system (HTPS) HyperPlan for the SIGMA-60 applicator (BSD Medical Corp., Salt Lake City, Utah, USA) has been evaluated with respect to clinical practicability and correctness. Materials and Methods: HyperPlan modules extract tissue boundaries from computed tomography (CT) images to generate regular and tetrahedral grids as patient models, to calculate electric field (E-field) distributions, and to visualize three-dimensional data sets. The finite difference time-domain (FDTD) method is applied to calculate the specific absorption rate (SAR) inside the patient. Temperature distributions are calculated by a finite-element code and can be optimized. HyperPlan was tested on 6 patients with pelvic tumors. For verification, measured SAR values were compared with calculated SAR values. Furthermore, intracorporeal E-field scans were performed and compared with calculated profiles. Results: The HTPS can be applied under clinical conditions. Measured absolute SAR (in W/kg), as well as relative E-field scans, correlated well with calculated values (±20%) using the contour-based FDTD method. Values calculated by applying the FDTD method directly on the voxel (CT) grid, were less well correlated with measured data. Conclusion: The HyperPlan system proved to be clinically feasible, and the results were quantitatively and qualitatively verified for the contour-based FDTD method

    In general men tend to drink more alcohol and experience more alcohol-related sickness, injuries and mortality than women. In this paper, the overall hypothesis was that increased gender similarity in the division of parental duties would lead to convergence in alcohol-related harm. The aim was to analyse whether the risk of alcohol harm differs between parents who fit a gender-stereotypical versus those with a less gender-stereotypical division of childcare and paid work. The study sample was a retrospective registry-based cohort study of all Swedish couples who had their first child together in 1978 (N = 49,120). A less gender-stereotypical parenthood was indicated by paternity leave for fathers (1978-1979) and full-time work for mothers (1980). The outcome was inpatient care and/or death caused by alcohol psychosis, alcoholism, liver disease, or alcohol intoxication in the two decades following (1981-2001). Our main statistical method was multivariate logistic regression with odds ratios used to estimate relative risks. The main results show that fathers who took paternity leave had 18% lower risk of alcohol-related care and/or death than other fathers. Mothers who worked full-time about two years after having a child had 71% higher risk than mothers who were unemployed or worked part-time. A less gender-stereotypical division of duties between parents in early parenthood may contribute to a long-term decreased gender disparity regarding risky alcohol consumption and alcohol-related harm. In order to know more about the causal direction however, future research has to consider subjects' drinking patterns in the years prior to parenthood.

The aim was to analyse whether the risk of alcohol harm differs between parents who fit a gender-stereotypical versus those with a less gender-stereotypical division of childcare and paid work. Methods The study sample was a retrospective registry-based cohort study of all Swedish couples who had their first child together in 1978 (N = 49,120). A less gender-stereotypical parenthood was indicated by paternity leave for fathers (1978–1979) and full-time work for mothers (1980). The outcome was inpatient care and/or death caused by alcohol psychosis, alcoholism, liver disease, or alcohol intoxication in the two decades following (1981–2001). Our main statistical method was multivariate logistic regression with odds ratios used to estimate relative risks. Results The main results show that fathers who took paternity leave had 18% lower risk of alcohol-related care and/or death than other fathers. Mothers who worked full-time about two years after having a child had 71% higher risk than mothers who were unemployed or worked part-time. Conclusion A less gender-stereotypical division of duties between parents in early parenthood may contribute to a long-term decreased gender disparity regarding risky alcohol consumption and alcohol-related harm. In order to know more about the causal direction however, future research has to consider subjects' drinking patterns in the years prior to parenthood. PMID:18793385

    In comparison to its female counterpart, the transition of men to parenthood has been relatively neglected in previous research. The present paper argues that men may have gender-specific risk factors for perinatal psychological distress and may manifest distress in ways different from women. The prime objective of this research was to document changes in psychological, relationship and lifestyle parameters in a cohort of first time fathers from pregnancy to the end of the first postnatal year. The present paper reports on these changes. Three hundred and twelve men were assessed at 23 weeks of pregnancy and followed up at 3, 6 and 12 months postnatally, using a battery of self-report questionnaires covering psychological symptom levels, lifestyle variables and relationship/sexual functioning. Two hundred and four men completed all four assessments. The men exhibited highest symptom levels in pregnancy with general, through small, improvement at 3 months and little change thereafter. Lifestyle variables showed small changes over the first postnatal year. Sexual functioning appeared to deteriorate markedly from pre-pregnancy levels with only minimal recovery by the end of the first year. The results highlight that the majority of men anticipated return of sexual activity to pre-pregnancy levels; however, this failed to eventuate. Pregnancy, rather than the postnatal period, would appear to be the most stressful period for men undergoing the transition to parenthood. The results suggest that the most important changes occur relatively early in pregnancy. Thereafter, lack of change (rather than change) is the most noteworthy feature. These men appeared to be ill-prepared for the impact of parenthood on their lives, especially in terms of the sexual relationship. Further research to determine the timing and trigger of stress in pregnancy is recommended.

    To compare fertility and childbearing attitudes and decisions of Portuguese and American female reproductive aged breast cancer survivors. This was a cross-sectional study of 102 young breast cancer survivors (59 from Portugal and 43 from USA). Demographic, clinical and reproductive information were collected. Fertility and parenthood attitudes and decisions were assessed through a self-report questionnaire devised specifically for the study. Fertility issues became very important after the diagnosis for most of the women (51%). Few differences existed between USA and Portuguese participants. USA participants were more likely to undergo FP (23% USA vs Portugal 5%, p = 0.01). Portuguese women were more dissatisfied with their physician's explanations about fertility (Portugal: 23% vs USA: 3%; p = 0.01). Overall, women relied on their oncologist for fertility information (70%); only Portuguese women discussed fertility with their family medicine physician (11%). Overall, women showed positive attitudes towards motherhood. Portuguese women were more likely to report their partners placed more value on the family after their illness (Portuguese agree: 55% vs USA agree: 14%; p USA and Portuguese samples were found on fertility and childbearing attitudes and decisions.

    The transition to parenthood is a potentially vulnerable time for mothers' mental health and approximately 9-21% of women experience depression and/or anxiety at this time. Many more experience sub-clinical symptoms of depression and anxiety, as well as stress, low self-esteem and a loss of confidence. Women's emotional wellbeing is more at risk if they have little social support, a low income, are single parents or have a poor relationship with their partner. Peer support can comprise emotional, affirmational, informational and practical support; evidence of its impact on emotional wellbeing during pregnancy and afterwards is mixed. This was a descriptive qualitative study, informed by phenomenological social psychology, exploring women's experiences of the impact of organised peer support on their emotional wellbeing during pregnancy and in early parenthood. Semi-structured qualitative interviews were undertaken with women who had received peer support provided by ten projects in different parts of England, including both projects offering 'mental health' peer support and others offering more broadly-based peer support. The majority of participants were disadvantaged Black and ethnic minority women, including recent migrants. Interviews were audio-recorded and transcripts were analysed using inductive thematic analysis. 47 mothers were interviewed. Two key themes emerged: (1) 'mothers' self-identified emotional needs', containing the subthemes 'emotional distress', 'stressful circumstances', 'lack of social support', and 'unwilling to be open with professionals'; and (2) 'how peer support affects mothers', containing the subthemes 'social connection', 'being heard', 'building confidence', 'empowerment', 'feeling valued', 'reducing stress through practical support' and 'the significance of "mental health" peer experiences'. Women described how peer support contributed to reducing their low mood and anxiety by overcoming feelings of isolation, disempowerment and

    What are the levels of awareness regarding female fertility and the intentions and attitudes towards parenthood among Chinese university students in Hong Kong compared with their counterparts in the West? Chinese university students in Hong Kong were similarly over-optimistic about the age-related fertility decline, although they were less inclined to have children and undergo fertility treatment compared with their Western counterparts. Past studies of highly educated young adults in Europe and the USA have found that they are not sufficiently aware of the age-related decline in female fertility, and falsely believe that advanced reproductive treatments such as IVF will overcome fertility problems associated with age. Little is known about the perceptions of Chinese students in Hong Kong, a modernized Chinese city where the fertility rate is among the lowest in the world. An online cross-sectional survey of Chinese university students in Hong Kong was conducted in 2013. Results were compared with two similar studies in Sweden and the USA. A total of 367 university students in Hong Kong (275 female, 92 male; mean age 23) responded to an e-mail invitation to participate in an online survey. Intentions and attitudes towards parenthood and awareness regarding female fertility were assessed using the Swedish Fertility Awareness Questionnaire. Like their Western counterparts, a large proportion of Chinese university students underestimated the age-related fertility decline (92%) and overestimated the fertility treatment success rate (66%). However, they were less inclined to have children, were more aware of and less concerned with infertility and were less motivated to seek solutions in the event of a fertility problem. These comparisons were significant at P International comparisons warrant caution because the Hong Kong sample was older than the US sample (mean age 20), but not older than the Sweden sample (mean age 24). While this study was consistent with past

    Perioperative care is complex and involves multiple interconnected subsystems. Delayed starts, prolonged cases and overtime are common. Surgical procedures account for 40-70% of hospital revenues and 30-40% of total costs. Most planning and scheduling in healthcare is done without modern planning tools, which have potential for improving access by assisting in operations planning support. We identified key planning scenarios of interest to perioperative leaders, in order to examine the feasibility of applying combinatorial optimization software solving some of those planning issues in the operative setting. Perioperative leaders desire a broad range of tools for planning and assessing alternate solutions. Our modeled solutions generated feasible solutions that varied as expected, based on resource and policy assumptions and found better utilization of scarce resources. Combinatorial optimization modeling can effectively evaluate alternatives to support key decisions for planning clinical workflow and improving care efficiency and satisfaction.

    A formal, hospitalwide strategic-planning process provides structure for the pharmacy's plans for implementing clinical services. The state-supported clinical cancer and research center began a formal strategic-planning process in 1981. The institution's planning report, prepared every two years and covering three two-year periods, drives the institution's budget through the state's biennial budget process. The report focuses on each department's responsibilities, areas of service, and relationship to the mission of the institution. Through the long-range planning process, upper-level administrators learned that pharmacy was eager not only to provide high-volume drug distribution services but also to assume direct patient-care and research responsibilities. This prompted an organizational change for pharmacy from a hospital department to a clinical division. The division of pharmacy now consists of three professional departments (patient care, pharmacy research, and pharmacy academic programs) and an administrative support service area. Services offered by each of the three departments are discussed, along with specific initiatives planned for the years 1987-1993. Within the next few years, all managers will come from the ranks of clinical practitioners; nonpharmacists will oversee financial and human resource functions. The division encourages existing pharmacy staff members to enhance their clinical skills through staff development programs. Strategic planning serves the dual purposes of structuring plans for implementing clinical pharmacy services and communicating pharmacy's goals within the institution.

    Full text: This study uses re-evaluates the doses delivered by a series of clinical stereotactic radiotherapy treatments, to test the accuracy of treatment planning predictions for very small radiation fields. Stereotactic radiotherapy treatment plans for meningiomas near the petrous temporal bone and the foramen magnum (incorp rating fields smaller than I c m2) were examined using Monte Carlo simulations. Important differences between treatment planning predictions and Monte Carlo calculations of doses delivered to stereotactic radiotherapy patients are apparent. For example, in one case the Monte Carlo calculation shows that the delivery a planned meningioma treatment would spare the patient's critical structures (eyes, brainstem) more effectively than the treatment plan predicted, and therefore suggests that this patient could safely receive an increased dose to their tumour. Monte Carlo simulations can be used to test the dose predictions made by a conventional treatment planning system, for dosimetrically challenging small fields, and can thereby suggest valuable modifications to clinical treatment plans.

    Although many empirical findings support associations between marital satisfaction and depressive symptoms, gaps remain in our understanding of the magnitude and direction of the associations between marital satisfaction and depressive symptoms as well as the associations in a collectivistic culture. The present study examined autoregressive cross-lagged associations between marital satisfaction and maternal depressive symptoms across a 3-year investigation in a sample of Korean mothers transitioning to parenthood. The sample consisted of 2,078 mothers in the Panel Study of Korean Children. The mothers reported marital satisfaction and maternal depressive symptoms annually for 3 years. The results of an autoregressive cross-lagged model revealed bidirectional associations between marital satisfaction and maternal depressive symptoms. The findings provide evidence of an interactional model of depression in a sample of Korean mothers. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Using data from the first two waves of the Netherlands Kinship Panel Study for 338 women and 262 men, we examine the consequences of making the transition to parenthood for life satisfaction, loneliness, positive affect, negative affect, and partnership satisfaction. We extend previous work by taking transitions in partner status and work hours into account. Results show a moderate impact of becoming a parent on well-being. In so far as effects of making the transition to parenthood emerge, they are attributable to changes in partner status and work hours. First, the decrease in negative affect upon making the transition to motherhood is attributable to the group of women who increase their working hours. Second, the detrimental impact of making the transition to motherhood on partnership satisfaction is attributable to the group of new mothers who quit their job. Third, the detrimental impact of making the transition to fatherhood on loneliness is attributable to the group of new fathers who become married. There is one exception to this pattern of partner status and work hours as mechanisms for changes in well-being. Men who become fathers remain less satisfied with their partnership, even when transitions in partner status and work hours have been taken into account. In the discussion-section, we consider the possible underestimation of negative effects because of the focus on the continuously partnered. We also reflect on our results in the light of the high incidence of part-time work in the Netherlands and Dutch policies aimed at supporting new parents.

    Age at sexual debut and age gap between partners at debut are modifiable characteristics that may be related to risky sexual behaviors. Understanding any such relationships is a necessary first step toward strengthening risk interventions. Age at sexual debut and partner age gap were examined for 3,154 female and 2,713 male respondents to the 2011-2013 National Survey of Family Growth who first had intercourse before age 18. Multivariable logistic regression was used to assess associations between these measures and teenage parenthood and reporting a high lifetime number of partners (i.e., a number above the sample median). Females' odds of teenage parenthood were elevated if sexual debut occurred at ages 15-17 and involved a partner age gap of 3-4 years (odds ratio, 1.8) or more (2.0); they were reduced if debut occurred before age 15 and the gap was 3-4 years (0.8). Females' likelihood of reporting a high lifetime number of partners was negatively associated with age gap (0.4-0.7, depending on age at debut and length of age gap). Males' likelihood of reporting a large number of partners was positively associated with age gap if sexual debut was before age 15 and the gap was five or more years (1.7) or if debut was at ages 15-17 and involved a 3-4-year gap (2.0). Identifying the mechanisms underlying these associations could inform program design and implementation. Copyright © 2017 by the Guttmacher Institute.

    Background This study examined the efficacy of a family planning clinic-based intervention to address intimate partner violence (IPV) and reproductive coercion. Study Design Four free-standing urban family planning clinics in Northern California were randomized to intervention (trained family planning counselors) or standard-of-care. English-and Spanish-speaking females ages 16-29 years (N=906) completed audio computer-assisted surveys prior to a clinic visit and 12 to 24 weeks later (75% retention rate). Analyses included assessment of intervention effects on recent IPV, awareness of IPV services, and reproductive coercion. Results Among women reporting past 3-month IPV at baseline, there was a 71% reduction in the odds of pregnancy coercion among participants in intervention clinics compared to participants from the control clinics that provided standard of care. Women in the intervention arm were more likely to report ending a relationship because the relationship was unhealthy or unsafe regardless of IPV status (AOR 1.63, 95% CI 1.01 – 2.63). Conclusions Results of this pilot study suggest that this intervention may reduce risk for reproductive coercion from abusive male partners among family planning clients and support such women to leave unsafe relationships.

    1983-01-01

    Mexico's private, nonprofit social marketing company, known as PROFAM, intends to expand its family planning clinics to marginal urban areas. The clinics are part of PROFAM's push to diversify social marketing outlets for contraceptive products and other birth control methods. PROFAM expects to establish 3 new clinics, possibly including a pregnancy test laboratory, a small 1-doctor clinic, and a large clinic housing an operating room. 1 clinic will be located outside the Mexico City area, the program's traditional boundaries. The company currently runs 2 small clinics and a pregnancy testing laboratory in Ciudad Netzahualcoyti, a community of 3.5 million on Mexico City's outskirts. PROFAM recently obtaine d government approval to sell condoms in food stores, which should increase distribtuion and sales. Currently, the company sells over 1 million high quality, lubricated condoms each month, accounting for over half of the Mexican market. Distribution covers 85% of the country's drugstore. Program setbacks occurred in 1981, when the Mexican government cancelled PROFAM's sales permits for all contraceptive products except condoms. Cancelled products included an oral contraceptive and 3 vaginal spermicides. These 4 products had provided nearly 100,000 couple years of protection in 1979 and an estimated 120,000 CYP 1980. During 1979 and 1980, condoms provided about 27,000 and 60,000 CYP, respectively. PROFAM had relied heavily on the pill and spermicides because its early studies showed condoms had a negative image in Mexico, due largely to the product's association with extramarital affairs. To counter this, PROFAM launched a widespread, free product sampling program in 1979, along with a continuing educational and advertising drive. Subsequent consumer surveys revealed a marked increase in product acceptance, with PROFAM's condom becoming the most widely known brand available in Mexico.

  3. A Business Case Framework for Planning Clinical Nurse Specialist-Led Interventions.

    2015-01-01

    The purpose of this article is to describe a business case framework that can guide clinical nurse specialists (CNS) in clinical intervention development. Increased emphasis on cost-effective interventions in healthcare requires skills in analyzing the need to make the business case, especially for resource-intensive interventions. This framework assists the CNS to anticipate resource use and then consider if the intervention makes good business sense. We describe a business case framework that can assist the CNS to fully explore the problem and determine if developing an intervention is a good investment. We describe several analyses that facilitate making the business case to include the following: problem identification and alignment with strategic priorities, needs assessment, stakeholder analysis, market analysis, intervention implementation planning, financial analysis, and outcome evaluation. The findings from these analyses can be used to develop a formal proposal to present to hospital leaders in a position to make decisions. By aligning intervention planning with organizational priorities and engaging patients in the process, interventions will be more likely to be implemented in practice and produce robust outcomes. The business case framework can be used to justify to organization decision makers the need to invest resources in new interventions that will make a difference for quality outcomes as well as the financial bottom line. This framework can be used to plan interventions that align with organizational strategic priorities, plan for associated costs and benefits, and outcome evaluation. Clinical nurse specialists are well positioned to lead clinical intervention projects that will improve the quality of patient care and be cost-effective. To do so requires skill development in making the business case.

    2000-03-01

    Baltimore-based Planned Parenthood of Maryland and the Baltimore City Health Department have joined forces in "EC to Go," which distributes free emergency contraceptive pills (ECPs) through the seven affiliate sites of Planned Parenthood and the three family planning centers of the city. The distribution program was started in October 1999 and funds were provided by an undisclosed area foundation. Although the program is still in its infancy, it has recorded some 800 prescriptions of ECPs in the last fiscal year, and 600 prescriptions have been logged in just the first 6 months of the current fiscal year. To inform the public about the program, Planned Parenthood developed newspaper advertisements, a 60-second radio spot, and coupon distributions, all of which emphasize the fact that emergency contraception is a higher dose of birth control, which can prevent pregnancy if taken within 72 hours of unprotected sex.

    During the 1970s, there was a decline in adolescent childbearing in the United States and, among teenagers who were sexually active, there was a decline in pregnancy rates as well. To what extent was increased enrollment by teenagers in federally funded family planning clinics responsible for these declines? Areal multivariate analysis reveals that adolescent birthrates were reduced between 1970 and 1975 as the result of enrollment by teenagers in family planning clinics, independent of the effects of other factors also affecting fertility, such as poverty status, education and urbanization. Using a model which controls for differences in adolescent sexual activity in different areas in 1970 and 1975, the analysis found that for every 10 teenage patients enrolled in family planning clinics in 1975, about one birth was averted in 1976. Other multivariate models, which did not control for differences in sexual activity, showed changes in the same direction, though of smaller dimension. Since the family planning program averts not only births but also pregnancies that result in abortions and miscarriages, an estimate was made of the total number of pregnancies averted by the program. Based on the proportion of unintended pregnancies among adolescents that resulted in live births in 1976 (36 percent), it was estimated that for every 10 teen patients enrolled in 1975, almost three pregnancies were averted in the following year. Over the 1970s, an estimated 2.6 million unintended adolescent pregnancies were averted by the program--944,000 births, 1,376,000 abortions and 326,000 miscarriages. In 1979 alone, an estimated 417,000 unintended pregnancies were prevented by the program.

    To explore organizations' experiences providing family planning during the first year of an expanded primary care program in Texas. Between November 2014 and February 2015, in-depth interviews were conducted with program administrators at 30 organizations: 7 women's health organizations, 13 established primary care contractors (e.g., community health centers, public health departments), and 10 new primary care contractors. Interviews addressed organizational capacities to expand family planning and integrate services with primary care. Interview transcripts were analyzed using a theme-based approach. Themes were compared across the three types of organizations. Established and new primary care contractors identified several challenges expanding family planning services, which were uncommon among women's health organizations. Clinicians often lacked training to provide intrauterine devices and contraceptive implants. Organizations often recruited existing clients into family planning services, rather than expanding their patient base, and new contractors found family planning difficult to integrate because of clients' other health needs. Primary care contractors frequently described contraceptive provision protocols that were not evidence-based. Many primary care organizations in Texas initially lacked the capacity to provide evidence-based family planning services that women's health organizations already provided. © Health Research and Educational Trust.

    2003-01-01

    Inaccurate dose calculations and limitations of optimization algorithms in inverse planning introduce systematic and convergence errors to treatment plans. This work was to implement a Monte Carlo based inverse planning model for clinical IMRT aiming to minimize the aforementioned errors. The strategy was to precalculate the dose matrices of beamlets in a Monte Carlo based method followed by the optimization of beamlet intensities. The MCNP 4B (Monte Carlo N-Particle version 4B) code was modified to implement selective particle transport and dose tallying in voxels and efficient estimation of statistical uncertainties. The resulting performance gain was over eleven thousand times. Due to concurrent calculation of multiple beamlets of individual ports, hundreds of beamlets in an IMRT plan could be calculated within a practical length of time. A finite-sized point source model provided a simple and accurate modeling of treatment beams. The dose matrix calculations were validated through measurements in phantoms. Agreements were better than 1.5% or 0.2 cm. The beamlet intensities were optimized using a parallel platform based optimization algorithm that was capable of escape from local minima and preventing premature convergence. The Monte Carlo based inverse planning model was applied to clinical cases. The feasibility and capability of Monte Carlo based inverse planning for clinical IMRT was demonstrated. Systematic errors in treatment plans of a commercial inverse planning system were assessed in comparison with the Monte Carlo based calculations. Discrepancies in tumor doses and critical structure doses were up to 12% and 17%, respectively. The clinical importance of Monte Carlo based inverse planning for IMRT was demonstrated

    2018-01-02

    Recent expansion of the legal definition of parenthood in New York State raises the question of whether the presence of a genetic relationship between a parent and child trumps environmental and interpersonal factors in the formation of a strong, secure attachment bond. The purpose of this paper is to emphasize that attachment between a child and secure attachment figure is inherently biological, and that such biological attachment supersedes the existence of a genetic parent-child relationship. First, the paper provides an overview of attachment and its biological basis. It then discusses the impact on attachment of environmental and interpersonal influences, which current research suggests have the power to alter brain biology. There is no clear evidence that a genetic relationship confers a significant advantage in terms of attachment. This paper proposes that the term "biological parent" be redefined to include anyone with whom a child shares a strong attachment bond.

    Purpose: With increasing numbers of cancer patients being diagnosed and the complexity of radiotherapy treatments rising it’s paramount that patient plan development continues to stay fluid within the clinic. In order to maintain a high standard of care and clinical efficiency the establishment of a tracking system for patient plan development allows healthcare providers to view real time plan progression and drive clinical workflow. In addition, it provides statistical datasets which can further identify inefficiencies within the clinic. Methods: An application was developed utilizing Microsoft’s ODBC SQL database engine to track patient plan status throughout the treatment planning process while also managing key factors pertaining to the patient’s treatment. Pertinent information is accessible to staff in many locations, including tracking monitors within dosimetry, the clinic network for both computers and handheld devices, and through email notifications. Plans are initiated with a CT and continually tracked through planning stages until final approval by staff. Patient’s status is dynamically updated by the physicians, dosimetrists, and medical physicists based on the stage of the patient’s plan. Results: Our application has been running over a six month period with all patients being processed through the system. Modifications have been made to allow for new features to be implemented along with additional tracking parameters. Based on in-house feedback, the application has been supportive in streamlining patient plans through the treatment planning process and data has been accumulating to further improve procedures within the clinic. Conclusion: Over time the clinic will continue to track data with this application. As data accumulates the clinic will be able to highlight inefficiencies within the workflow and adapt accordingly. We will add in new features to help support the treatment planning process in the future.

Plans are initiated with a CT and continually tracked through planning stages until final approval by staff. Patient’s status is dynamically updated by the physicians, dosimetrists, and medical physicists based on the stage of the patient’s plan. Results: Our application has been running over a six month period with all patients being processed through the system. Modifications have been made to allow for new features to be implemented along with additional tracking parameters. Based on in-house feedback, the application has been supportive in streamlining patient plans through the treatment planning process and data has been accumulating to further improve procedures within the clinic. Conclusion: Over time the clinic will continue to track data with this application. As data accumulates the clinic will be able to highlight inefficiencies within the workflow and adapt accordingly. We will add in new features to help support the treatment planning process in the future.

    In population planning in Latin America the programs are as successful as the government's support of family planning. Colombia is one of the few Latin American countries which has actively exhorted its populace to birth control. If the propensity for large families reflects a belief in the economic or social utility of children, instead of machismo, birthrates will fall with expanded social security and economic welfare programs. If birthrates are the result of machismo, new gender models stressing the positive rewards and social esteem to be gained through responsible parenthood would have to be taught to both adults and children. The position profamily planning in most Latin American countries is generally supported by the ministers, technocrats, corporations, businessmen, middle-class women, doctors, mass media, protestant congregations, and working-class women. Family planning is usually opposed by members of the armed forces, Catholic hierarchy, Catholic lay organizations, oligarchy, university students, leftist intellectuals, Marxist insurgents, Indian communities, and peasants. The portion of the total national populations encompassed by the groups composing the core combination, ideological bias, and stability group ranges from 50-60% in Argentina, Uruguay, and Venezuela to 10-20% in Central America, Bolivia, Ecuador, and Paraguay. Most groups are outside the policy-making process.

    True quality control (QC) of the planning process requires quantitative assessments of treatment plan quality itself, and QC in IMRT has been stymied by intra-patient anatomical variability and inherently complex three-dimensional dose distributions. In this work we describe the development of an automated system to reduce clinical IMRT planning variability and improve plan quality using mathematical models that predict achievable OAR DVHs based on individual patient anatomy. These models rely on the correlation of expected dose to the minimum distance from a voxel to the PTV surface, whereby a three-parameter probability distribution function (PDF) was used to model iso-distance OAR subvolume dose distributions. DVH models were obtained by fitting the evolution of the PDF with distance. Initial validation on clinical cohorts of 40 prostate and 24 head-and-neck plans demonstrated highly accurate model-based predictions for achievable DVHs in rectum, bladder, and parotid glands. By quantifying the integrated difference between candidate DVHs and predicted DVHs, the models correctly identified plans with under-spared OARs, validated by replanning all cases and correlating any realized improvements against the predicted gains. Clinical implementation of these predictive models was demonstrated in the PINNACLE treatment planning system by use of existing margin expansion utilities and the scripting functionality inherent to the system. To maintain independence from specific planning software, a system was developed in MATLAB to directly process DICOM-RT data. Both model training and patient-specific analyses were demonstrated with significant computational accelerations from parallelization.

    This longitudinal study investigated marital satisfaction trajectories across the first 2 years of parenthood. Data were collected from new parents (couples) 6 weeks before the birth of their first child, and then at 6, 12, 18, and 24 months postpartum. Growth curve models revealed two key findings. First, for highly anxious individuals, satisfaction was lower or declined when they perceived their partners as less supportive and as behaving more negatively toward them. Second, for highly avoidant individuals, satisfaction was lower or declined when they perceived more work-family conflict and greater demands from their families. The findings suggest that attachment insecurities predict dissatisfaction in new parents primarily when stressors block the pursuit of important attachment goals.

    Two dose calculation algorithms are available in Varian Eclipse software: Anisotropic Analytical Algorithm (AAA) and Acuros External Beam (AXB). Many Varian Eclipse-based centers have access to AXB; however, a thorough understanding of how it will affect plan characteristics and, subsequently, clinical practice is necessary prior to implementation. We characterized the difference in breast plan quality between AXB and AAA for dissemination to clinicians during implementation. Locoregional irradiation plans were created with AAA for 30 breast cancer patients with a prescription dose of 50 Gy to the breast and 45 Gy to the regional node, in 25 fractions. The internal mammary chain (IMC CTV ) nodes were covered by 80% of the breast dose. AXB, both dose-to-water and dose-to-medium reporting, was used to recalculate plans while maintaining constant monitor units. Target coverage and organ-at-risk doses were compared between the two algorithms using dose-volume parameters. An analysis to assess location-specific changes was performed by dividing the breast into nine subvolumes in the superior-inferior and left-right directions. There were minimal differences found between the AXB and AAA calculated plans. The median difference between AXB and AAA for breast CTV V 95% , was AAA for breast radiotherapy is not expected to result in changes in clinical practice for prescribing or planning breast radiotherapy. © 2018 The Authors.

    2014-03-01

    Computer based Treatment Planning Systems (TPS) are used worldwide to design and calculate treatment plans for treating radiation therapy patients. TPS are generally well designed and thoroughly tested by their developers and local physicists prior to clinical use. However, the wide-reaching impact of their accuracy warrants ongoing vigilance. This work reviews the findings of the Australian national audit system and provides recommendations for checks of TPS. The Australian Clinical Dosimetry Service (ACDS) has designed and implemented a national system of audits, currently in a three year test phase. The Level III audits verify the accuracy of a beam model of a facility's TPS through a comparison of measurements with calculation at selected points in an anthropomorphic phantom. The plans are prescribed by the ACDS and all measurement equipment is brought in for independent onsite measurements. In this first version of audits, plans are comparatively simple, involving asymmetric fields, wedges and inhomogeneities. The ACDS has performed 14 Level III audits to-date. Six audits returned at least one measurement at Action Level, indicating that the measured dose differed more than 3.3% (but less than 5%) from the planned dose. Two audits failed (difference >5%). One fail was caused by a data transmission error coupled with quality assurance (QA) not being performed. The second fail was investigated and reduced to Action Level with the onsite audit team finding phantom setup at treatment a contributing factor. The Action Level results are attributed to small dose calculation deviations within the TPS, which are investigated and corrected by the facilities. Small deviations exist in clinical TPS which can add up and can combine with output variations to result in unacceptable variations. Ongoing checks and independent audits are recommended.

    Youth in Latin America experience high rates of teen pregnancy and sexually transmitted infections, but traditional health services are not meeting their health care needs. Youth require access to tailored health care and information to make informed, healthy decisions. To break down barriers to these vital sexual and reproductive health services, Planned Parenthood Global, a division of Planned Parenthood Federation of America, developed a Youth Peer Provider model which has been implemented in Latin America since the early 1990s. The model goes beyond peer education to train Youth Peer Providers under age 20 to provide condoms, oral contraceptive pills, emergency contraception, injectable contraceptives, and sexual and reproductive health information to their peers. Peers with needs beyond Youth Peer Providers' capacity are referred to health professionals offering youth-friendly services. Survey results reveal high levels of contraceptive use among those served by the Youth Peer Providers: 98% of sexually active survey respondents wishing to avoid pregnancy report contraceptive use at least five years after joining the programme. Results of qualitative programme evaluations highlight higher self-esteem, stronger communication and decision-making skills, close relationships with friends and family, more interest in school, understanding of responsibility in relationships, and other positive outcomes among programme participants.

    2017-01-01

    In research on fatherhood premiums and motherhood penalties in career-related outcomes, employers discriminatory behaviours are often argued to constitute a possible explanation for observed gender gaps. However, there is as yet no conclusive evidence of such discrimination. Utilizing a field experiment design, we test (i) whether job applicants are subject to recruitment discrimination on the basis of their gender and parenthood status, and (ii) whether discrimination by gender and parenthoo...

All clinical trials tools, including QA software, require testing for validity and reliability. enabling inter- and intra-trial comparison. Unlike clinical radiotherapy treatment planning (RTP) systems, review software has no published guidelines. This study describes the design and development of a test suite to quantify the performance of review software in TROG clinical trials. Test areas are image handling and reconstruction; geometric accuracy; dosimetric accuracy; dose-volume histogram (DVH) calculation; display of plan parameters. TROG have developed tests for commissioning plan review software, assessed with SWAN 2.3, and CMS Elekta FocalPro. While image handling tests were based on published guidelines for RTP systems, dosimetric tests used the TROG QA case review requirements. Treatment plans represented systems of all manufacturers (Pinnacle, Eclipse, Xio and Oncentra) used in Australasian centres. The test suite identified areas for SW A software development, including the DVH algorithm, changed to reduce calculation time. Results, in Fig. I, for known volumes of varying shapes and sizes, demonstrate differences between SWAN 2.1 and 2.3 when compared with Eclipse. Liaison with SWAN programmers enabled re-instatement of 2.1 algorithm. The test suite has quantified the RTP review software, prioritised areas for development with the programmers, and improved the user experience.

  19. Adolescents' sensitivity to children's supernatural thinking: A preparation for parenthood?

    Hernández Blasi, Carlos; Bjorklund, David F

    2018-05-01

    Young children often use magical explanations to account for ordinary phenomena (e.g., "The sun's not out today because it is mad"). We labeled these explanations supernatural thinking. Previous research reports that supernatural thinking attributed to preschool-age children evokes both positive affect and perceptions of helplessness from both adults and older (14-17 years old) but not younger (10-13 years old) adolescents. In this study, we asked if cues of cognitive immaturity are more influential in affecting adolescents' judgments of children than physical cues (faces). 245 adolescents aged between 10 and 17 rated pairs of children who physically and/or cognitively resembled either a 4- to 7-year-old or an 8- to 10-year-old child in three between-subject conditions (Consistent, Inconsistent, Faces-Only) for 14 traits classified into four trait dimensions (Positive Affect, Negative Affect, Intelligence, Helplessness). For both younger and older adolescents, cognitive cues had a greater influence on judgments than facial cues. However, only the older adolescents demonstrated a positive bias for children expressing immature supernatural thinking. Adopting an evolutionary developmental perspective, we interpreted this outcome in late (but not early) adolescence as preparation for potential parenthood.

    Using donor conception treatment for family building brings challenges as well as rewards. As social model approaches to managing genetic difference within families gradually replace earlier medical models, parents are encouraged to be open with their children about their origins amidst greater social acceptance. Little is known about effective interventions to help prospective parents prepare for such family life. A survey was sent to participants in 16 Preparation for Parenthood workshops run in England by Donor Conception Network, a peer support organisation, between 2008 and 2010. The 79 respondents (32.4% response) included heterosexual couples, lesbian couples and single women considering sperm, egg or double donation. In 86% couples, both partners responded. The use of a range of techniques, a family lifespan approach, facilitators with personal as well as professional experience, medical and psychosocial specialists, and access to peer support were well received. Results suggest the value of attending cognitive and affective processes, acknowledging the impact of stigma and discussing how the donor's biography/presence can be conjoined with that of the new family. Findings suggest workshop approaches to donor conception parenthood preparation can be useful for prospective lesbian/single women/heterosexual-headed families considering donor conception. Such interventions have not previously been reported.

  1. Redefining parenthood: surviving the death of a child.

    Nuss, Suzanne L

    2014-01-01

    Although dying children are often aware of their impending death, parents are reluctant to communicate with their dying child about death. The objective of this study was to examine how parents of children in the advanced stage of a life-threatening disease trajectory communicated about death. Using grounded theory methods, data were collected via interviews with 18 parents of children who had died of an advanced life-threatening disease. Ways in which parents communicated with their dying child were impacted by the degree of threat to the parental role. From the onset of their child's life-threatening illness, the sense of parental self was threatened, resulting in "Parental Vulnerability." To endure parental vulnerability, parents confronted a process of "Redefining Parenthood." Before the child's death, parents experienced (1) Protecting From Fears, (2) Protecting Normalcy, (3) Protecting Faith, (4) Experiencing Protection From Their Child, and (5) Bookmarking Memories. After the child's death, parents experienced (1) Telling the Story, (2) Making Meaning, (3) Protecting the Child's Memory, (4) Defining a New Normal, and (5) Learning to Live With Regret. Results provide new information about the experiences of parents of dying children as they communicated with their child during the dying process and as they found ways to go on with life after their child's death. Findings can be used by healthcare professionals to help support families of dying children. The field of pediatric oncology nursing would benefit from exploration of the dying child's perspective.

    to explore the experiences and perceptions of parenthood and maternal health care among Latin American women living in Spain. an exploratory qualitative research using focus groups and thematic analysis of the discussion. three focus groups with 26 women from Bolivia and Ecuador and three focus groups with 24 midwives were performed in three towns in the Valencian Community receiving a large influx of immigrants. the women interpreted motherhood as the role through which they achieve fulfilment and assumed that they were the ones who could best take care of their children. They perceived that men usually make decisions about sex and pregnancy and recognised a poor or inadequate use of contraceptive methods in planning their pregnancies. Women reported that it was not necessary to go as soon and as frequently for health examinations during pregnancy as the midwives suggested. The main barriers identified to health-care services were linked to insecure or illegal employment status, inflexible appointment timetables for prenatal checkups and sometimes to ignorance about how public services worked. empowering immigrant women is essential to having a long-term positive effect on their reproductive health. Antenatal care providers should be trained to build maternity care that is culturally sensitive and responds better to the health needs of different pregnant women and their newborns.

    Community health clinics serving the poor and underserved are geographically expanding due to changes in U.S. health care policy. This paper describes the experience of a collaborative alliance of health care providers in a large metropolitan area who develop a conceptual and mathematical decision model to guide decisions on expanding its network of community health clinics. Community stakeholders participated in a collaborative process that defined constructs they deemed important in guiding decisions on the location of community health clinics. This collaboration also defined key variables within each construct. Scores for variables within each construct were then totaled and weighted into a community-specific optimal space planning equation. This analysis relied entirely on secondary data available from published sources. The model built from this collaboration revolved around the constructs of demand, sustainability, and competition. It used publicly available data defining variables within each construct to arrive at an optimal location that maximized demand and sustainability and minimized competition. This is a model that safety net clinic planners and community stakeholders can use to analyze demographic and utilization data to optimize capacity expansion to serve uninsured and Medicaid populations. Communities can use this innovative model to develop a locally relevant clinic location-planning framework.

    Theory suggests that the impact of neighborhood poverty depends on both the duration and timing of exposure. Previous research, however, does not properly analyze the sequence of neighborhoods to which children are exposed throughout the early life course. This study investigates the effects of different longitudinal patterns of exposure to disadvantaged neighborhoods on the risk of adolescent parenthood. It follows a cohort of children in the PSID from age 4 to 19 and uses novel methods for time-varying exposures that overcome critical limitations of conventional regression when selection processes are dynamic. Results indicate that sustained exposure to poor neighborhoods substantially increases the risk of becoming a teen parent and that exposure to neighborhood poverty during adolescence may be more consequential than exposure earlier during childhood.

    Technical requirements for Monte Carlo based electron radiotherapy treatment planning are outlined. The targeted overall accuracy for estimate of the delivered dose is the least restrictive of 5% in dose, 5 mm in isodose position. A system based on EGS4 and capable of achieving this accuracy is described. Experience gained in system design and commissioning is summarized. The key obstacle to widespread clinical use of Monte Carlo is lack of clinically acceptable measurement based methodology for accurate commissioning

    2015-11-15

    As of January 1, 2016, microbiology laboratories can choose to adopt a new quality control option, the Individualized Quality Control Plan (IQCP), under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). This voluntary approach increases flexibility for meeting regulatory requirements and provides laboratories the opportunity to customize QC for their testing in their unique environments and by their testing personnel. IQCP is an all-inclusive approach to quality based on risk management to address potential errors in the total testing process. It includes three main steps, (1) performing a risk assessment, (2) developing a QC plan, and (3) monitoring the plan through quality assessment. Resources are available from the Centers for Medicare & Medicaid Services, Centers for Disease Control and Prevention, American Society for Microbiology, Clinical and Laboratory Standards Institute, and accrediting organizations, such as the College of American Pathologists and Joint Commission, to assist microbiology laboratories implementing IQCP.

    2015-01-01

    We aim to define a site-specific robustness protocol to be used during the clinical plan evaluation process. Plan robustness of 16 skull base IMPT plans to systematic range and random set-up errors have been retrospectively and systematically analysed. This was determined by calculating the error-bar dose distribution (ebDD) for all the plans and by defining some metrics used to define protocols aiding the plan assessment. Additionally, an example of how to clinically use the defined robustness database is given whereby a plan with sub-optimal brainstem robustness was identified. The advantage of using different beam arrangements to improve the plan robustness was analysed. Using the ebDD it was found range errors had a smaller effect on dose distribution than the corresponding set-up error in a single fraction, and that organs at risk were most robust to the range errors, whereas the target was more robust to set-up errors. A database was created to aid planners in terms of plan robustness aims in these volumes. This resulted in the definition of site-specific robustness protocols. The use of robustness constraints allowed for the identification of a specific patient that may have benefited from a treatment of greater individuality. A new beam arrangement showed to be preferential when balancing conformality and robustness for this case. The ebDD and error-bar volume histogram proved effective in analysing plan robustness. The process of retrospective analysis could be used to establish site-specific robustness planning protocols in proton therapy. These protocols allow the planner to determine plans that, although delivering a dosimetrically adequate dose distribution, have resulted in sub-optimal robustness to these uncertainties. For these cases the use of different beam start conditions may improve the plan robustness to set-up and range uncertainties. (paper)

    1986-09-01

    A pharmacy department at a 340-bed community hospital based its strategic plan for developing patient-oriented services on a sound drug distribution system, a credible work-measurement program, and fiscal responsibility. In 1982 the department of pharmacy and i.v. therapy implemented a strategic plan for improving pharmaceutical services. The plan involved developing goals and objectives for the department; marketing the department's services and fiscal management to hospital administrators, medical staff, and nursing staff; building teamwork among the pharmacy staff; and improving the drug distribution system before instituting clinical services. Hiring of additional pharmacy staff was justified on the basis of work-measurement data. By adjusting staffing levels every two weeks based on work-measurement data, the department increased the efficiency of drug distribution activities; the pharmacy also implemented cost-saving programs like selection of therapeutic alternates and formulary restrictions. The savings were then reinvested in labor-intensive patient-oriented pharmaceutical services. A staff development program using staff pharmacists as preceptors expanded the breadth and depth of pharmacists' clinical skills. The planning efforts were successful because the needs of hospital administrators, the pharmacy department, and staff members were addressed.

    Computer based Treatment Planning Systems (TPS) are used worldwide to design and calculate treatment plans for treating radiation therapy patients. TPS are generally well designed and thoroughly tested by their developers and local physicists prior to clinical use. However, the wide-reaching impact of their accuracy warrants ongoing vigilance. This work reviews the findings of the Australian national audit system and provides recommendations for checks of TPS. The Australian Clinical Dosimetry Service (ACDS) has designed and implemented a national system of audits, currently in a three year test phase. The Level III audits verify the accuracy of a beam model of a facility's TPS through a comparison of measurements with calculation at selected points in an anthropomorphic phantom. The plans are prescribed by the ACDS and all measurement equipment is brought in for independent onsite measurements. In this first version of audits, plans are comparatively simple, involving asymmetric fields, wedges and inhomogeneities. The ACDS has performed 14 Level III audits to-date. Six audits returned at least one measurement at Action Level, indicating that the measured dose differed more than 3.3% (but less than 5%) from the planned dose. Two audits failed (difference >5%). One fail was caused by a data transmission error coupled with quality assurance (QA) not being performed. The second fail was investigated and reduced to Action Level with the onsite audit team finding phantom setup at treatment a contributing factor. The Action Level results are attributed to small dose calculation deviations within the TPS, which are investigated and corrected by the facilities. Small deviations exist in clinical TPS which can add up and can combine with output variations to result in unacceptable variations. Ongoing checks and independent audits are recommended.

    The goal of this work is to develop a plan-quality evaluation program for clinical routine and multi-institutional clinical trials so that the overall evaluation efficiency is improved. In multi-institutional clinical trials evaluating the plan quality is a time-consuming and labor-intensive process. In this note, we present a semi-automated plan-quality evaluation program which combines MIMVista, Java/MATLAB, and extensible markup language (XML). More specifically, MIMVista is used for data visualization; Java and its powerful function library are implemented for calculating dosimetry parameters; and to improve the clarity of the index definitions, XML is applied. The accuracy and the efficiency of the program were evaluated by comparing the results of the program with the manually recorded results in two RTOG trials. A slight difference of about 0.2% in volume or 0.6 Gy in dose between the semi-automated program and manual recording was observed. According to the criteria of indices, there are minimal differences between the two methods. The evaluation time is reduced from 10-20 min to 2 min by applying the semi-automated plan-quality evaluation program.

    2006-09-01

    Clinics that receive Title X funding have a mandate to encourage parent-child communication for minors seeking family planning services. Little is known about the programs and practices that clinics have adopted to achieve this goal, or whether clinics not receiving Title X funds encourage family participation. As part of a larger project examining parental engagement among adolescents using family planning clinics, 81 clinics that served 200 or more adolescent contraceptive clients in 2001 completed a questionnaire containing closed- and open-ended items. Topic areas included clinic counseling and policies regarding clients younger than 18, activities to improve parent-child communication and community relations. Frequency distributions were calculated for the prevalence of activities, and cross-tabulations were used to compare prevalence by clinic characteristics. Every clinic engaged in at least one activity to promote parent-child communication, and nine in 10 offered multiple activities. Most of the clinics used counseling sessions to talk to adolescent clients about the importance of discussing sexual health issues with parents (73-94%, depending on the reason for the visit). More than eight in 10 clinics (84%) distributed pamphlets on how to talk about these issues. A substantial minority (43%) offered or referred interested individuals to educational programs designed to improve communication. Some of these exploratory findings reflect the prevalence of activities among all U.S. family planning clinics that serve adolescent clients. Evaluation and expansion of clinic efforts to promote voluntary communication about sexual health issues between parents and children could help encourage family participation.

    Many nursing students enter undergraduate programmes with preconceived ideas about their future nursing careers, and intend to practice in particular areas such as midwifery or paediatrics. Through clinical placements, students are exposed to different clinical areas and professional socialization is facilitated. However, little is known about the influence of clinical placements on students' career intentions. This paper reports nursing findings drawn from a large qualitative study conducted in Victoria, Australia that sought to explore the influence of health professional students' clinical placements on their future career intentions. Participants were invited to be involved in either face-to-face or focus group interviews depending upon their own preference. Thematic data analysis revealed three main themes: 're-affirming career choice', 'working in a particular area' and 'work location'. Findings from the study add to our understanding of factors influencing nursing students' planning for their future careers including the impact of clinical placements.

    Four main clinical issues need to be considered for HIV-positive individuals and couples with respect to pregnancy planning and counselling: (1) pre-conceptional health; (2) transmission from mother to infant, which has been significantly reduced by combined antiretroviral therapy; (3) transmission between partners during conception, which requires different prevention and treatment strategies depending on the status and needs of those involved; and (4) management of infertility issues. The objective of the Canadian HIV Pregnancy Planning Guidelines is to provide clinical information and recommendations for health care providers to assist HIV-positive individuals and couples with their fertility and pregnancy planning decisions. These guidelines are evidence- and community-based and flexible, and they take into account diverse and intersecting local/population needs and the social determinants of health. Intended outcomes are (1) reduction of risk of vertical transmission and horizontal transmission of HIV, (2) improvement of maternal and infant health outcomes in the presence of HIV, (3) reduction of the stigma associated with pregnancy and HIV, and (4) increased access to pregnancy planning and fertility services. PubMed and Medline were searched for articles published in English or French to December 20, 2010, using the following terms: "HIV" and "pregnancy" or "pregnancy planning" or "fertility" or "reproduction" or "infertility" or "parenthood" or "insemination" or "artificial insemination" or "sperm washing" or "IVF" or "ICSI" or "IUI." Other search terms included "HIV" and 'horizontal transmission" or "sexual transmission" or "serodiscordant." The following conference databases were also searched: Conference on Retroviruses and Opportunistic Infections, International AIDS Conference, International AIDS Society, Interscience Conference on Antimicrobial Agents and Chemotherapy, the Canadian Association of HIV/AIDS Research, and the Ontario HIV Treatment

    We assessed the impact of staff, clinic, and community interventions on male and female family planning client visit volume and sexually transmitted infection testing at a multisite community-based health care agency. Staff training, clinic environmental changes, in-reach/outreach, and efficiency assessments were implemented in two Family Health Center (San Diego, CA) family planning clinics during 2010-2012; five Family Health Center family planning programs were identified as comparison clinics. Client visit records were compared between preintervention (2007-2009) and postintervention (2010-2012) for both sets of clinics. Of 7,826 male client visits during the time before intervention, most were for clients who were aged male visits (4,004 to 8,385; Δ = +109%); for comparison clinics, male visits increased modestly (3,822 to 4,500; Δ = +18%). The proportion of male clinic visits where chlamydia testing was performed increased in intervention clinics (35% to 42%; p males yielded similar findings for male client volume and chlamydia testing. The number of female visits declined nearly 40% in both comparison (21,800 to 13,202; -39%) and intervention clinics (30,830 to 19,971; -35%) between preintervention and postintervention periods. Multilevel interventions designed to increase male client volume and sexually transmitted infection testing services in family planning clinics succeeded without affecting female client volume or services.

    Purpose: To develop an automated radiotherapy treatment planning and optimization workflow for prostate cancer in order to generate clinical treatment plans. Methods: A fully automated radiotherapy treatment planning and optimization workflow was developed based on the treatment planning system Monaco (Elekta AB, Stockholm, Sweden). To evaluate our method, a retrospective planning study (n=100) was performed on patients treated for prostate cancer with 5 field intensity modulated radiotherapy, receiving a dose of 35×2Gy to the prostate and vesicles and a simultaneous integrated boost of 35×0.2Gy to the prostate only. A comparison was made between the dosimetric values of the automatically and manually generated plans. Operator time to generate a plan and plan efficiency was measured. Results: A comparison of the dosimetric values show that automatically generated plans yield more beneficial dosimetric values. In automatic plans reductions of 43% in the V72Gy of the rectum and 13% in the V72Gy of the bladder are observed when compared to the manually generated plans. Smaller variance in dosimetric values is seen, i.e. the intra- and interplanner variability is decreased. For 97% of the automatically generated plans and 86% of the clinical plans all criteria for target coverage and organs at risk constraints are met. The amount of plan segments and monitor units is reduced by 13% and 9% respectively. Automated planning requires less than one minute of operator time compared to over an hour for manual planning. Conclusion: The automatically generated plans are highly suitable for clinical use. The plans have less variance and a large gain in time efficiency has been achieved. Currently, a pilot study is performed, comparing the preference of the clinician and clinical physicist for the automatic versus manual plan. Future work will include expanding our automated treatment planning method to other tumor sites and develop other automated radiotherapy workflows.

    Full Text Available This study examines how inter-organizational mobility affects earnings inequality based on gender and parenthood under different macroeconomic conditions. Fixed effects regression analysis of Survey of Income and Program Participation data from 2004 to 2012 shows that earnings growth after quitting jobs for work-related reasons (e.g., to improve one’s job situation is greater for women than for men pre-recession, but the trend is driven by childless women, and mothers of children under six benefit the least among all groups of workers. However, this motherhood wage penalty disappears in the 2008 recession, as a result of the decline of wage returns to mobility for childless women. The analysis also shows that across economic conditions, the rate of layoffs or displacement is higher among men than women, but once laid off, women experience greater earnings losses than men. No motherhood penalty is found for this mobility type. These findings help us understand the longitudinal process by which the motherhood wage penalty is generated, and conditions under which a motherhood-based or gender-based wage gap becomes more pronounced.

    The use of three-dimensional replicas created using laserlithography has recently become popular for surgical planning and intraoperative navigation in plastic surgery and oral maxillofacial surgery. In this study, we investigated many clinical applications that we have been involved in regarding the production of three-dimensional replicas. We have also analyzed the features, application classes, and advantages of this method. As a result, clinical applications are categorized into three classes, which are 'three-dimensional shape recognition', 'simulated surgery', and 'template'. The distinct features of three-dimensional replicas are 'direct recognition', 'fast manipulation', and 'free availability'. Meeting the requirements of surgical planning and intraoperative navigation, they have produced satisfactory results in clinical applications. (author)

    2016-01-01

    Clinical registries are a powerful method to observe the clinical practice and natural disease history. In contrast to clinical trials, where guidelines and standardized methods exist and are mandatory, only a few initiatives have published methodological guidelines for clinical registries. The objective of this paper was to review these guidelines and systematically assess their completeness, usability and feasibility according to a SWOT analysis. The results show that each guideline has its own strengths and weaknesses. While one supports the systematic planning process, the other discusses clinical registries in great detail. However, the feasibility was mostly limited and the special requirements of clinical registries, their flexible, expandable and adaptable technological structure was not addressed consistently.

    Research into the process of becoming mother or father shows very conclusively that this important life transition is accompanied by both a decrease in marital quality and a more traditional division of labour. In this paper these changes are analyzed with special emphasis on the relationships between them and exploring the role played in this process by the mother's work status. Results showed a significant link between the development of marital quality and violated expectations regarding father involvement on childrearing. Dual-earner families were characterized by a specific pattern of changes, with greater stability than single-earner families in marital and parental roles during transition to parenthood and a significant role played by spouse support as a partner, but not as a parent.

    Although family and lifestyle are known to be important factors for medical students choosing a specialty, there is a lack of research about general surgery residency program policies regarding pregnancy and parenthood. Similarly, little is known about program director attitudes about these issues. We performed a cross-sectional survey of United States (US) general surgery residency program directors. Sixty-six respondents completed the survey: 70% male, 59% from university-based programs, and 76% between 40 and 59 years of age. Two-thirds (67%) reported having a maternity leave policy. Less than half (48%) reported having a leave policy for the non-childbearing parent (paternity leave). Leave duration was most frequently reported as 6 weeks for maternity leave (58%) and 1 week for paternity leave (45%). Thirty-eight percent of general surgery residency program directors (PDs) reported availability of on-site childcare, 58% reported availability of lactation facilities. Forty-six percent of university PDs said that the research years are the best time to have a child during residency; 52% of independent PDs said that no particular time during residency is best. Sixty-one percent of PDs reported that becoming a parent negatively affects female trainees' work, including placing an increased burden on fellow residents (33%). Respondents perceived children as decreasing female trainees' well-being more often than male trainees' (32% vs 9%, p leave, length of leave, as well as inconsistency in access to childcare and availability of spaces to express and store breast milk. Program directors perceived parenthood to affect the training and well-being of female residents more adversely than that of male residents. Copyright © 2016 American College of Surgeons.

    This study adopted a person (actor) by partner perspective to examine how actor personality traits, partner personality traits, and specific actor by partner personality trait interactions predict actor's depressive symptoms across the first two years of the transition to parenthood. Data were collected from a large sample of new parents (both partners in each couple) 6 weeks before the birth of their first child, and then at 6, 12, 18, and 24 months postpartum. The results revealed that higher actor neuroticism and lower partner agreeableness predicted higher levels of depressive symptoms in actors. Moreover, the specific combination of high actor neuroticism and low partner agreeableness was a particularly problematic combination, which was intensified when prepartum dysfunctional problem-solving communication and aggression existed in the relationship. These results demonstrate the importance of considering certain actor by partner disposition pairings to better understand actors' emotional well-being during major life transitions.

  8. Family life clinics for Gulf state: Bahrain FPA helps bring a family planning breakthrough.

    1979-01-01

    Family life clinics which will provide family planning services alongside maternal and child health services and general counseling are opening in health centers throughout Bahrain and in the main hospital at Manama. Bahrain, a small island in the Arabian Gulf, formed its first Family Planning Association (FPA) just 4 years ago; and this new initiative is seen as a direct result of cooperation between FPA and the government. To spread family planning awareness and services particularly to the poorer section of the population, Bahrain's FPA developed in various stages. Stage 1, in 1975, was to attract and educate volunteers and channel their interest into special committees dealing with programs; public relations; child welfare; legal and medical affairs; research; and conferences and education. Stage 2 came with the need to coordinate the work and set up a 2-person staff and an office. Stage 3 developed with the first field campaign. Door-to-door visiting was tried but was not popular with volunteers or residents. Approaching the population through community clubs and institutions was tried with much success. The new family life clinics are the latest stage of a fruitful cooperation between FPA and the Ministry of Labor and Social Affairs. In addition to the new family life clinics, an active effort to improve family planning awareness has continued using national seminars and mass media. Fund-raising is under way for a mobile,clinic which will provide health services and methods of contraception, to which there is still substantial resistance, to many on the island who have no exposure to the mass media. Wide acceptance of the need for family planning for the sake of mothers, the family, and the child is growing in Bahrain.

    Background Up to 18% of men experience depression and/or anxiety during the transition to parenthood. Interventions designed specifically to promote the mental health of men during the transition to parenthood are scarce. Internet-delivered interventions may be acceptable and far-reaching in enhancing mental health, parenting knowledge, and healthy behaviors in expectant or new fathers. Objective To guide the development of Healthydads.ca, a website designed to enhance mental health and healthy behaviors in expectant fathers, a needs assessment was conducted to identify fathers’ perspectives of barriers to seeking help for emotional wellness, informational needs, and factors affecting the decision to visit such a website. Methods One hundred and seventy-four men whose partners were expecting, or had recently given birth, in 3 Canadian provinces (Quebec, Ontario, and Alberta) completed a Web-based survey inquiring about information needs related to psychosocial aspects of the transition to parenthood, lifestyle behaviors, parenting, and factors associated with the decision to visit a father-focused website. Results Most men (155/174, 89.1%) reported accessing the Internet to obtain information on pregnancy and spent an average of 6.2 hours online per month. Seeking information about parenting on the Internet was reported by 67.2% (117/174) of men, with a mean of 4.4 hours per month of online searching. Top barriers to seeking help to improve emotional wellness during the perinatal period were: no time to seek help/assistance (130/174, 74.7%), lack of resources available in the health care system (126/174, 72.4%), financial costs associated with services (118/174, 67.8%), and feeling that one should be able to do it alone (113/174, 64.9%). Information needs that were rated highly included: parenting/infant care (52.9-81.6%), supporting (121/174, 69.5%) and improving (124/174, 71.3%) relationship with their partner, work-family balance (120/174, 69.0%), improving

    2015-01-01

    We examined the impact of legislation in Texas that dramatically cut and restricted participation in the state’s family planning program in 2011 using surveys and interviews with leaders at organizations that received family planning funding. Overall, 25% of family planning clinics in Texas closed. In 2011, 71% of organizations widely offered long-acting reversible contraception; in 2012–2013, only 46% did so. Organizations served 54% fewer clients than they had in the previous period. Specialized family planning providers, which were the targets of the legislation, experienced the largest reductions in services, but other agencies were also adversely affected. The Texas experience provides valuable insight into the potential effects that legislation proposed in other states may have on low-income women’s access to family planning services. PMID:25790404

    LGBT clients have unique healthcare needs but experience a wide range of quality in the care that they receive. This study provides a summary of clinical guideline recommendations related to the provision of primary care and family planning services for LGBT clients. In addition, we identify gaps in current guidelines, and inform future recommendations and guidance for clinical practice and research. PubMed, Cochrane, and Agency for Healthcare Research and Quality electronic bibliographic databases, and relevant professional organizations' websites, were searched to identify clinical guidelines related to the provision of primary care and family planning services for LGBT clients. Information obtained from a technical expert panel was used to inform the review. Clinical guidelines meeting the inclusion criteria were assessed to determine their alignment with Institute of Medicine (IOM) standards for the development of clinical practice guidelines and content relevant to the identified themes. The search parameters identified 2,006 clinical practice guidelines. Seventeen clinical guidelines met the inclusion criteria. Two of the guidelines met all eight IOM criteria. However, many recommendations were consistent regarding provision of services to LGBT clients within the following themes: clinic environment, provider cultural sensitivity and awareness, communication, confidentiality, coordination of care, general clinical principles, mental health considerations, and reproductive health. Guidelines for the primary and family planning care of LGBT clients are evolving. The themes identified in this review may guide professional organizations during guideline development, clinicians when providing care, and researchers conducting LGBT-related studies.

    Using longitudinal time diary and survey data from a community sample of dual-earner couples across the transition to parenthood, the authors examined change in divisions of paid and unpaid work and assessed the accuracy of survey data for time use measurement. Mothers, according to the time diaries, shouldered the majority of child care and did not decrease their paid work hours. Furthermore, the gender gap was not present prebirth but emerged postbirth with women doing more than 2 hours of additional work per day compared to an additional 40 minutes for men. Moreover, the birth of a child magnified parents' overestimations of work in the survey data, and had the authors relied only on survey data, gender work inequalities would not have been apparent. The findings have important implications for (a) the state of the gender revolution among couples well positioned to obtained balanced workloads and (b) the utility of survey data to measure parents' division of labor.

    This study examined the role of parenthood and parental influences on substance use patterns for 710 stimulant users age 18-61 living in the rural Midwest and Mid-south U.S. Longitudinal growth analyses showed that a maternal history of drug use was associated with increased baseline drug use severity, lesser declines in severity, and greater plateau of drug use severity over time. Parental conflict was associated with lesser declines in drug use severity, and drug use severity declined more steeply for participants who were themselves parents. Participants with two parents having a history of alcohol use had a greater baseline severity of alcohol use, with paternal history of drug use associated with lower baseline alcohol use severity. These findings demonstrate the importance of identifying parental influences in evaluating adult substance use, and point to the inclusion of parents in efforts to prevent and treat substance use disorders. © 2018 Family Process Institute.

    In the following, we will present a newly developed X-ray calibration phantom and its integration for 2-D/3-D pelvis reconstruction and subsequent automatic cup planning. Two different planning strategies were applied and evaluated with clinical data. Two different cup planning methods were investigated: The first planning strategy is based on a combined pelvis and cup statistical atlas. Thereby, the pelvis part of the combined atlas is matched to the reconstructed pelvis model, resulting in an optimized cup planning. The second planning strategy analyzes the morphology of the reconstructed pelvis model to determine the best fitting cup implant. The first planning strategy was compared to 3-D CT-based planning. Digitally reconstructed radiographs of THA patients with differently severe pathologies were used to evaluate the accuracy of predicting the cup size and position. Within a discrepancy of one cup size, the size was correctly identified in 100% of the cases for Crowe type I datasets and in 77.8% of the cases for Crowe type II, III, and IV datasets. The second planning strategy was analyzed with respect to the eventually implanted cup size. In seven patients, the estimated cup diameter was correct within one cup size, while the estimation for the remaining five patients differed by two cup sizes. While both planning strategies showed the same prediction rate with a discrepancy of one cup size (87.5%), the prediction of the exact cup size was increased for the statistical atlas-based strategy (56%) in contrast to the anatomically driven approach (37.5%). The proposed approach demonstrated the clinical validity of using 2-D/3-D reconstruction technique for cup planning.

    The Nigerian Family Health services project teamed up with the Johns Hopkins University's Population Communication Services to produce songs called "Choices" and "Wait for Me." The songs, which were about sexual responsibility, were performed by popular music stars King Sunny Ade and Onyeka Onwenu and appeared under King Sonny Ade's long playing albums in 1989. Teaching sexual responsibility through song was suggested in focus group discussions. Findings indicated that young people were responsive to messages about sexual responsibility, postponing sex or saying "no," male sexual responsibility, and children by informed choice and not chance among married couples. An impact assessment of the songs was conducted in February, 1991. Survey findings revealed that 64% of urban and 22% of rural respondents recalled having heard the songs and seen the videos. 48% of urban youth discussed the songs with friends, and 27% discussed the songs with sexual partners. 90% of respondents reported agreement with the message that couples should have only the number of children that they can care for, and that couples should practice family planning. The target population that was affected most by the songs was aged less than 35 years. The strategy of using songs to teach youth responsible parenting appears to be a reliable strategy for mass education and mobilization. There is mass support from among members of the National Council for Women's Societies, the Planned Parenthood Federation of Nigeria, and Coca Cola Corporation, as well as the public at large.

To guide the development of Healthydads.ca, a website designed to enhance mental health and healthy behaviors in expectant fathers, a needs assessment was conducted to identify fathers' perspectives of barriers to seeking help for emotional wellness, informational needs, and factors affecting the decision to visit such a website. One hundred and seventy-four men whose partners were expecting, or had recently given birth, in 3 Canadian provinces (Quebec, Ontario, and Alberta) completed a Web-based survey inquiring about information needs related to psychosocial aspects of the transition to parenthood, lifestyle behaviors, parenting, and factors associated with the decision to visit a father-focused website. Most men (155/174, 89.1%) reported accessing the Internet to obtain information on pregnancy and spent an average of 6.2 hours online per month. Seeking information about parenting on the Internet was reported by 67.2% (117/174) of men, with a mean of 4.4 hours per month of online searching. Top barriers to seeking help to improve emotional wellness during the perinatal period were: no time to seek help/assistance (130/174, 74.7%), lack of resources available in the health care system (126/174, 72.4%), financial costs associated with services (118/174, 67.8%), and feeling that one should be able to do it alone (113/174, 64.9%). Information needs that were rated highly included: parenting/infant care (52.9-81.6%), supporting (121/174, 69.5%) and improving (124/174, 71.3%) relationship with their partner, work-family balance (120/174, 69.0%), improving sleep (100/174, 57.5%), and managing

    Designing a radiation plan that optimally delivers both target coverage and normal tissue sparing is challenging. There are limited tools to determine what is dosimetrically achievable and frequently the experience of the planner/physician is relied upon to make these determinations. PlanIQ software provides a tool that uses target and organ at risk (OAR) geometry to indicate the difficulty of achieving different points for organ dose-volume histograms (DVH). We hypothesized that PlanIQ Feasibility DVH may aid planners in reducing dose to OARs. Clinically delivered head and neck treatments (clinical plan) were re-planned (re-plan) putting high emphasis on maximally sparing the contralateral parotid gland, contralateral submandibular gland, and larynx while maintaining routine clinical dosimetric objectives. The planner was blinded to the results of the clinically delivered plan as well as the Feasibility DVHs from PlanIQ. The re-plan treatments were designed using 3-arc VMAT in Raystation (RaySearch Laboratories, Sweden). The planner was then given the results from the PlanIQ Feasibility DVH analysis and developed an additional plan incorporating this information using 4-arc VMAT (IQ plan). The DVHs across the three treatment plans were compared with what was deemed "impossible" by PlanIQ's Feasibility DVH (Impossible DVH). The impossible DVH (red) is defined as the DVH generated using the minimal dose that any voxel outside the targets must receive given 100% target coverage. The re-plans performed blinded to PlanIQ Feasibilty DVH achieved superior sparing of aforementioned OARs compared to the clinically delivered plans and resulted in discrepancies from the impossible DVHs by an average of 200-700 cGy. Using the PlanIQ Feasibility DVH led to additionalOAR sparing compared to both the re-plans and clinical plans and reduced the discrepancies from the impossible DVHs to an average of approximately 100 cGy. The dose reduction from clinical to re-plan and re-plan to

    Purpose: An artificial intelligence (AI) guided method for parameter adjustment of inverse planning was implemented on a commercial inverse treatment planning system. For evaluation purpose, four typical clinical cases were tested and the results from both plans achieved by automated and manual methods were compared. Methods and materials: The procedure of parameter adjustment mainly consists of three major loops. Each loop is in charge of modifying parameters of one category, which is carried out by a specially customized fuzzy inference system. A physician prescribed multiple constraints for a selected volume were adopted to account for the tradeoff between prescription dose to the PTV and dose-volume constraints for critical organs. The searching process for an optimal parameter combination began with the first constraint, and proceeds to the next until a plan with acceptable dose was achieved. The initial setup of the plan parameters was the same for each case and was adjusted independently by both manual and automated methods. After the parameters of one category were updated, the intensity maps of all fields were re-optimized and the plan dose was subsequently re-calculated. When final plan arrived, the dose statistics were calculated from both plans and compared. Results: For planned target volume (PTV), the dose for 95% volume is up to 10% higher in plans using the automated method than those using the manual method. For critical organs, an average decrease of the plan dose was achieved. However, the automated method cannot improve the plan dose for some critical organs due to limitations of the inference rules currently employed. For normal tissue, there was no significant difference between plan doses achieved by either automated or manual method. Conclusion: With the application of AI-guided method, the basic parameter adjustment task can be accomplished automatically and a comparable plan dose was achieved in comparison with that achieved by the manual

    Introduction: The impact of pregnancy and parenthood on the long-term course of PCOS (polycystic ovary syndrome is still not known. The LIPCOS study (Lifestyle Intervention for Patients with Polycystic Ovary Syndrome [PCOS] - using the example of pregnancy and parenthood) systematically investigates long-term changes in PCOS symptoms. Method and Patients: The LIPCOS pilot study sent out a questionnaire to 403 patients who had presented with oligomenorrhea between 1991 and 2002. The prospective LIPCOS main study systematically investigated 64 women using structured interviews about lifestyle changes in the last 10 years, created a detailed hormone profile of these women and carried out vaginal ultrasound to calculate ovarian score. Results: Ovarian volume and ovarian score were not significantly lower for women with children (n = 25) compared to women with PCOS who had not had children (n = 39; p = 0.226). More women with children than women who did not have children currently reported a regular daily lifestyle, and the difference was statistically significant (92 % [n = 23/25] vs. 61.5 % [n = 24/39]; p = 0.009). Ten years ago or before the birth of their first child, respectively, no such difference was found between both groups (52 vs. 51.3 %). Over the last 10 years, women with children were more likely to have shorter cycles compared to women without children (p = 0.441). 88 % of women with children compared to 69.2 % of women without children reported that currently they had a "healthy diet" (p = 0.130). Serum testosterone levels were slightly lower for women with children (67.6 % of the upper limits of normal ranges) compared to women without children (80 % of the upper limits of normal ranges), but because of the small subgroup sizes the difference was not statistically significant (p = 0.106). Conclusion: The LIPCOS study shows for the first time that pregnancy and parenthood may have an impact on the long

    A conference on awareness in the mass media of the problems of family planning was held in March 1989 at Bissau by the Guinean Association for Education and Promotion of Family Health (AGEPSF). Representatives of radio, a daily newspaper, and the national press agency discussed the objectives of AGEPSF and the benefits of family planning with specialists in different sectors of national life. The secretary general of AGEPSF affirmed the interest of the government in creating a health organization to coordinate national policy in family planning and to diffuse information on family planning. The family planning objective of the AGEPSF is not limitation of births but rather spacing to promote maternal and child health. AGEPSF is a member of the International Planned Parenthood Federation and maintains relations with similar organizations throughout the world. According to the director of the national maternity hospital, family planning is a sensitive topic but it has become accepted in numerous countries as marriage in rural areas and abortions in urban areas are widespread practices in Africa with potentially grave consequences. The general director of the National Institute for Studies and Research placed the theme of family planning in the context of Guinea-Bissau by citing the low level of education, the almost insignificant number of literate women, and the lack of health services in rural areas as the principal causes of increasing infant mortality in the country. African countries should create favorable conditions, elevate the level of living of their populations, and develop concrete health actions to reduce infant and maternal mortality.

    Purpose: Development, application and evaluation of a CT-guided implantation technique and a fully CT based treatment planning procedure for brachytherapy. Methods and Materials : A brachytherapy procedure based on CT-guided implantation technique and CT based treatment planning has been developed and clinically evaluated. For this purpose a software system (PROMETHEUS) for the 3D reconstruction of brachytherapy catheters and patient anatomy using only CT scans has been developed. An interface for the Nucletron Plato BPS treatment planning system for the optimisation and calculation of dose distribution has been devised. The planning target volume(s) are defined as sets of points using contouring tools and are for optimisation of the 3D dose distribution. Dose-volume histogram-based analysis of the dose distribution enables a clinically realistic evaluation of the brachytherapy application to be made. The CT-guided implantation of catheters and the CT-based treatment planning procedure has been performed for interstitial brachytherapy and for different tumour and anatomical localizations in 197 patients between 1996 and 1997. Results : The accuracy of the CT reconstruction was tested using a quality assurance phantom an an interstitial implant of 12 needles and compared with the results of reconstruction using radiographs[hs. Both methods give comparable results with regard to accuracy. The CT based reconstruction was faster. Clinical feasibility has been proven in pre-irradiated recurrences of brain tumour, in pre-treated recurrences or metastatic disease, and in breast carcinomas. The tumour volume treated ranged from 5.1 - 2741 cm3. Analysis of the implant quality showed a slight significant lower COIN value for the bone implants, but no differences in respect to the planning target volume. Conclusions : With the integration of CT imaging in the treatment planning and documentation of brachytherapy, we have a new CT based quality assurance method to evaluate

    The Great East Japan Earthquake on 11 March 2011 caused major damage in northeastern Japan. The Kanto region experienced a massive electrical power shortage in the summer of 2011. A questionnaire was submitted to 354 hemodialysis clinics in Kanagawa prefecture and the Tokyo metropolitan area, excluding isolated islands, and 176 responses were analyzed (49.7%). The questions included evaluation of the availability of a private electricity generator, countermeasures in case of a planned outage, awareness of saving electricity, and improvement of safety of medical devices or electrical facilities after the earthquake. Only 12% of the clinics had private electricity generators and many clinics had no plans to introduce this facility. However, 96% of the clinics had established countermeasures to deal with a planned outage. Many clinics planned to provide dialysis on a different day or at a different time. All clinics had tried hard to establish procedures to save electricity in the summer of 2011, and 84% of the clinics had reconsidered and improved the safety of medical devices or electricity facilities after the earthquake. These results show that the awareness of crisis management was greatly improved in the wake of the earthquake. © 2012 The Authors.

    Treatment planning is a crucial component of the Harvard-MIT boron neutron capture therapy (BNCT) clinical trials. Treatment planning can be divided into five stages: (1) pre-planning, based on CT and MRI scans obtained when the subject arrives at the hospital and on assumed boron-10 distribution parameters; (2) subject set-up, or simulation, in the MITR-II medical therapy room to determine the boundary conditions for possible set-up configurations; (3) re-planning, following the subject simulation; (4) final localization of the subject in the medical therapy room for BNCT; and (5) final post facto recalculation of the doses delivered based on firm knowledge of the blood boron-10 concentration profiles and the neutron flux histories from precise online monitoring. The computer-assisted treatment planning is done using a specially written BNCT treatment planning code called MacNCTPLAN. The code uses the Los Alamos National Laboratory's Monte Carlo n-particle radiation transport code MCNPv.4b as the dose calculation engine and advanced anatomical model simulation based on an automatic evaluation of CT scan data. Results are displayed as isodose contours and dose-volume histograms, the latter correlated precisely with corresponding anatomical CT or MRI image planes. Examples of typical treatment planning scenarios will be presented. (author)

    The resulting plans from a new type of treatment planning system called SharePlan have been studied. This software allows for the conversion of treatment plans generated in a TomoTherapy system for helical delivery, into plans deliverable on C-arm linear accelerators (linacs), which is of particular interest for clinics with a single TomoTherapy unit. The purpose of this work was to evaluate and compare the plans generated in the SharePlan system with the original TomoTherapy plans and with plans produced in our clinical treatment planning system for intensity-modulated radiation therapy (IMRT) on C-arm linacs. In addition, we have analyzed how the agreement between SharePlan and TomoTherapy plans depends on the number of beams and the total number of segments used in the optimization. Optimized plans were generated for three prostate and three head-and-neck (H&N) cases in the TomoTherapy system, and in our clinical treatment planning systems (TPS) used for IMRT planning with step-and-shoot delivery. The TomoTherapy plans were converted into step-and-shoot IMRT plans in SharePlan. For each case, a large number of Pareto optimal plans were created to compare plans generated in SharePlan with plans generated in the Tomotherapy system and in the clinical TPS. In addition, plans were generated in SharePlan for the three head-and-neck cases to evaluate how the plan quality varied with the number of beams used. Plans were also generated with different number of beams and segments for other patient cases. This allowed for an evaluation of how to minimize the number of required segments in the converted IMRT plans without compromising the agreement between them and the original TomoTherapy plans. The plans made in SharePlan were as good as or better than plans from our clinical system, but they were not as good as the original TomoTherapy plans. This was true for both the head-and-neck and the prostate cases, although the differences between the plans for the latter were

    Phantom tests are performed for pre-clinical evaluation of a commercial inverse planning system (HELAX TMS, V 6.0) for segmented multileaf collimator (MLC) intensity modulated radiotherapy (IMRT) delivery. The optimization module has available two optimization algorithms: the target primary feasibility and the weighted feasibility algorithm, only the latter allows the user to specify weights for structures. In the first series, single beam tests are performed to evaluate the outcome of inverse planning in terms of plausibility for the following situations: oblique incidence, presence of inhomogeneities, multiple targets at different depths and multiple targets with different desired doses. Additionally, for these tests a manual plan is made for comparison. In the absence of organs at risk, both the optimization algorithms are found to assign the highest priority to low dose constraints for targets. In the second series, tests resembling clinical relevant configurations (simultaneous boost and concave target with critical organ) are performed with multiple beam arrangements in order to determine the impact of the system's configuration on inverse planning. It is found that the definition of certain segment number and segment size limitations does not largely compromise treatment plans when using multiple beams. On the other hand, these limitations are important for delivery efficiency and dosimetry. For the number of iterations and voxels per volume of interest, standard values in the system's configuration are considered to be sufficient. Additionally, it is demonstrated that precautions must be taken to precisely define treatment goals when using computerized treatment optimization. Similar phantom tests could be used for a direct dosimetric verification of all steps from inverse treatment planning to IMRT delivery. (note)

    Purpose: To test the feasibility of a new inverse planning technology based on the Hybrid Inverse treatment Planning and Optimisation (HIPO) algorithm for image-guided cervical cancer brachytherapy in comparison to conventional manual optimisation as applied in recent clinical practice based on long-term intracavitary cervical cancer brachytherapy experience. Materials and methods: The clinically applied treatment plans of 10 tandem/ring (T/R) and 10 cases with additional needles (T/R + N) planned with PLATO v14.3 were included. Standard loading patterns were manually optimised to reach an optimal coverage with 7 Gy per fraction to the High Risk CTV and to fulfil dose constraints for organs at risk. For each of these patients an inverse plan was retrospectively created with Oncentra GYN v0.9.14. Anatomy based automatic source activation was based on the topography of target and organs. The HIPO algorithm included individual gradient and modification restrictions for the T/R and needle dwell times to preserve the spatial high-dose distribution as known from the long-term clinical experience in the standard cervical cancer brachytherapy and with manual planning. Results: HIPO could achieve a better target coverage (V100) for all T/R and 7 T/R + N patients. Changes in the shape of the overdose volume (V200/400) were limited. The D 2cc per fraction for bladder, rectum and sigmoid colon was on average lower by 0.2 Gy, 0.4 Gy, 0.2 Gy, respectively, for T/R patients and 0.6 Gy, 0.3 Gy, 0.3 Gy for T/R + N patients (a decrease from 4.5 to 4 Gy per fraction means a total dose reduction of 5 Gy EQD2 for a 4-fraction schedule). In general the dwell times in the additional needles were lower compared to manual planning. The sparing factors were always better for HIPO plans. Additionally, in 7 T/R and 7 T/R + N patients all three D 0.1cc , D 1cc and D 2cc for vagina wall were lower and a smaller area of vagina was covered by the reference dose in HIPO plans.

    Full Text Available Abstract Background The independent effects of stress on the health of primary care patients might be different for different types of clinic populations. This study examines these relationships in a low-income female population of patients attending a family planning clinic. Methods This study investigated the relevance of different sources of personal stress and social support to self-rated health, adjusting for mental health, health behavior and demographic characteristics of subjects. Five hundred women who attended family planning clinics were surveyed and 345 completed the form for a response rate of 72 percent. Results Multiple logistic regression analysis revealed that liking oneself was related to good self-rated health (Odds ratio = 7.11, but stress or support from children, parents, friends, churches or spouses were not significant. White non-Hispanic and non-white non-Hispanic respondents had lower odds of reporting good self-rated health than Hispanic respondents (odds ratios were 2.87 and 2.81, respectively. Exercising five or more days per week also was related to good self-rated health. Smoking 20 or more cigarettes per day, and obese III were negatively related to good self-rated health (odds ratios were .19 and .22, respectively with corresponding p-values equal to .0043 and .0332. Conclusions Among younger low-income women, addressing low self-esteem might improve health status.

    Full Text Available Abstract Background In order for clinical practice guidelines (CPGs to meet their broad objective of enhancing the quality of care and supporting improved patient outcomes, they must address the needs of diverse patient populations. We set out to explore the patient attributes that are likely to demand a unique approach to the management of chronic disease, and which are crucial if evidence or services planning is to reflect clinic populations. These were incorporated into a new conceptual framework; using diabetes mellitus as an exemplar. Methods The patient attributes that informed the framework were identified from CPGs, the diabetes literature, an expert academic panel, and two cross-disciplinary panels; and agreed upon using a modified nominal group technique. Results Full consensus was reached on twenty-four attributes. These factors fell into one of three themes: (1 type/stage of disease, (2 morbid events, and (3 factors impacting on capacity to self-care. These three themes were incorporated in a convenient way in the workforce evidence-based (WEB model. Conclusions While biomedical factors are frequently recognised in published clinical practice guidelines, little attention is given to attributes influencing a person's capacity to self-care. Paying explicit attention to predictable threats to effective self-care in clinical practice guidelines, by drawing on the WEB model, may assist in refinements that would address observed disparities in health outcomes across socio-economic groups. The WEB model also provides a framework to inform clinical training, and health services and workforce planning and research; including the assessment of healthcare needs, and the allocation of healthcare resources.

    Research into parenting and mental illness seldom includes forensic mental health service users, despite its relevance to therapeutic, family work and risk management. This study aimed to understand the experiences of parents and the variety of parenting roles maintained during admission to a secure forensic hospital. Narrative interviews with 18 parents (eight mothers and 10 fathers) at an English medium security hospital were analysed thematically, using the framework approach. The proportion of patients who are parents and their contact patterns with their children were estimated from records. About a quarter of men and 38% of women were parents. Parenthood was of central importance to their emotional life, spanning experiences of loss, shame and failed expectations, joy, responsibility and hope. Fewer fathers maintained contact with their children than mothers yet fatherhood remained a vital aspect of men's identities, with impact on their self-esteem. Parenting during lengthy admissions--while constrained and dependent on professional support and surveillance--ranged from sending gifts and money to visits and phone calls. Offending was seen as a particularly shameful aspect of admission, contributing to distancing from the children and difficulty explaining detention to them. Such complex experiences call for multidisciplinary knowledge and skills. Provision of focused therapy, as well as appropriate visiting spaces, creative approaches to contact time and support for patients in explaining their mental illness and detention to their children are recommended.

    The present study examined longitudinal associations between four family meal patterns (i.e. never had regular family meals, started having regular family meals, stopped having regular family meals, maintained having regular family meals) and young adult parents' dietary intake, weight-related behaviours and psychosocial well-being. In addition, family meal patterns of parents were compared with those of non-parents. Analysis of data from the longitudinal Project EAT (Eating and Activity in Adolescents and Young Adults) study. Linear and logistic regressions were used to examine the associations between family meal patterns and parents' dietary intake, weight-related behaviours and psychosocial well-being. School and in-home settings. At baseline (1998; EAT-I), adolescents (n 4746) from socio-economically and racially/ethnically diverse households completed a survey and anthropometric measurements at school. At follow-up (2015; EAT-IV), participants who were parents (n 726) and who were non-parents with significant others (n 618) completed an online survey. Young adult parents who reported having regular family meals as an adolescent and as a parent ('maintainers'), or who started having regular family meals with their own families ('starters'), reported more healthful dietary, weight-related and psychosocial outcomes compared with young adults who never reported having regular family meals ('nevers'; Pfamily meal starters than non-parents. Results suggest that mental and physical health benefits of having regular family meals may be realized as a parent whether the routine of regular family meals is carried forward from adolescence into parenthood, or if the routine is started in parenthood.

    2015-01-01

    Purpose: This paper introduces a method that maximizes the probability of satisfying the clinical goals in intensity-modulated radiation therapy treatments subject to setup uncertainty. Methods: The authors perform robust optimization in which the clinical goals are constrained to be satisfied whenever the setup error falls within an uncertainty set. The shape of the uncertainty set is included as a variable in the optimization. The goal of the optimization is to modify the shape of the uncertainty set in order to maximize the probability that the setup error will fall within the modified set. Because the constraints enforce the clinical goals to be satisfied under all setup errors within the uncertainty set, this is equivalent to maximizing the probability of satisfying the clinical goals. This type of robust optimization is studied with respect to photon and proton therapy applied to a prostate case and compared to robust optimization using an a priori defined uncertainty set. Results: Slight reductions of the uncertainty sets resulted in plans that satisfied a larger number of clinical goals than optimization with respect to a priori defined uncertainty sets, both within the reduced uncertainty sets and within the a priori, nonreduced, uncertainty sets. For the prostate case, the plans taking reduced uncertainty sets into account satisfied 1.4 (photons) and 1.5 (protons) times as many clinical goals over the scenarios as the method taking a priori uncertainty sets into account. Conclusions: Reducing the uncertainty sets enabled the optimization to find better solutions with respect to the errors within the reduced as well as the nonreduced uncertainty sets and thereby achieve higher probability of satisfying the clinical goals. This shows that asking for a little less in the optimization sometimes leads to better overall plan quality

    Since the start of radiotherapy, the aim of all radiotherapists has been to treat as many patients who suffer with malignant tumours as possible, so as to give an effective curative dose to the whole tumour, at the same time, doing as little damage as possible to normal tissues. Until 1945, damage to the skin was usually the limiting factor. Since the war, with the rapid development of more powerful X-ray machines and sources of irradiation, we have had at our disposal much more penetrating radiation, allowing us to give effective tumour doses, with little or no damage to the skin. However, with higher tumour doses, there is more likelihood of damage to structures in proximity to the tumour - i.e. bone, nerves, muscle, liver, kidney etc. This has focussed the interest of all radiologists on the need for careful planning, and physicists have worked out with great care the differential absorptions of X-rays on differing tissue, i. e. bone, muscle, fat etc., so that very accurate and correct treatment planning can now be undertaken. This entails a great deal of accurate and complicated work and has had to be done by our physicist colleagues, who may take hours or days to work out a complicated treatment plan. The acceptance of the plan as being the most suitable for a patient is governed by these factors: (a) The dose must be given to the whole tumour area; (b) The nearby structures, i. e. nerves, bowel, kidney etc. must not receive a dose which may cause serious damage; (c) All parts of the tumour must have an effective dose; (d) The integral dose must be such that the patient is not unduly upset. All these factors vary from patient to patient, and thus each plan has to be considered in conjunction with each individual patient so that, although patients have similar tumours, what may be an optimal plan for one may not be for another. Also clinicians themselves vary in their opinions on the size of tumour, general condition of the patient, and the amount of damage

    Traditionally, family planning initiatives were concentrated on women despite it being a family matter. As family dynamics evolved over the years, fathers' involvement in family planning has become crucial in enhancing the family well-being. This study aimed to identify the role played by men in family planning activities and the association of socio-economic characteristics with these roles. This was a cross-sectional study carried out in a university primary care clinic. All married male attendees to the clinic, aged 50 years and below, were approached to answer a set of self-administered questionnaires, asking for their involvement in family planning practices. The data were analysed using descriptive and inferential statistics. There were 167 participants in the study. A high proportion of men participated in the discussions regarding previous pregnancies (60.42%), future child planning (89.76%) and desired family size (89.76%). However, the discussions on the usage of family planning methods (FPMs; 39.16%) were significantly low. Socio-economic factors associated with higher likelihood of men discussing family planning activities were older age ( p family planning activities. The roles taken by men in family planning were associated with older age and higher socio-economic class. The majority of men needs to be encouraged to play a more active role in the discussion of FPMs.

    Full Text Available Unwanted pregnancies with their negative impact on both women and children occur on an ongoing basis in Gauteng, South Africa. One way to prevent unwanted pregnancies is to use a reliable contraceptive method available free of charge from primary health care clinics providing family planning services throughout Gauteng Province. A literature review was completed on women and access to family planning services and an interview schedule (questionnaire was developed. The purpose of this study was to describe guidelines to meet the expectations of clients accessing family planning services provided by a clinic in Region F, Area 28 of the Greater Johannesburg metropolitan council. This quantitative, exploratory, descriptive and comparative study measured the gaps between the expectations of participants on service delivery and the extent to which these expectations were met. A convenience sample was conducted and consisted of 50 women of reproductive age (ages 15 to 49 attending the family planning clinic. Pre-testing of the instrument was conducted. Structured interviews with a interview schedule were conducted before and after women attended a family planning service. Inferential statistics indicated that there was a significant gap between the client expectations of family planning service delivery and the extent to which these expectations were met. Of the sixty-four items where women indicated the extent of their expectations the findings on only three items were not statistically significant. These gaps were addressed by proposing managerial guidelines to be implemented by the nurse manager in charge of the facility, on which this article will focus. Validity and reliability principles were ensured in the study. Ethical principles were adhered to during the research process.

    Hyperthermia (HT) as an adjuvant to radiation therapy (RT) is a multimodality treatment method to enhance therapeutic efficacy in different tumours. High demands are placed on the hardware and treatment planning software to guarantee adequately planned and applied HT treatments. The aim of this prospective study was to determine the effectiveness and safety of the novel HT system in tumour-bearing dogs and cats in terms of local response and toxicity as well as to compare planned with actual achieved data during heating. A novel applicator with a flexible number of elements and integrated closed-loop temperature feedback control system, and a tool for patient-specific treatment planning were used in a combined thermoradiotherapy protocol. Good agreement between predictions from planning and clinical outcome was found in 7 of 8 cases. Effective HT treatments were planned and verified with the novel system and provided improved quality of life in all but 1 patient. This individualized treatment planning and controlled heat exposure allows adaptive, flexible and safe HT treatments in palliatively treated animal patients. © 2017 John Wiley & Sons Ltd.

    Radiosurgical treatment of brain metastases is well established in daily clinical routine. Utilization of flattening-filter-free beams (FFF) may allow for more rapid delivery of treatment doses and improve clinical comfort. Hence, we compared plan quality and efficiency of radiosurgery in FFF mode to FF techniques. Between November 2014 and June 2015, 21 consecutive patients with 25 brain metastases were treated with stereotactic radiosurgery (SRS) in FFF mode. Brain metastases received dose-fractionation schedules of 1 x 20 Gy or 1 x 18 Gy, delivered to the conformally enclosing 80 % isodose. Three patients with critically localized or large (>3 cm) brain metastases were treated with 6 x 5 Gy. Plan quality and efficiency were evaluated by analyzing conformity, dose gradients, dose to healthy brain tissue, treatment delivery time, and number of monitor units. FFF plans were compared to those using the FF method, and early clinical outcome and toxicity were assessed. FFF mode resulted in significant reductions in beam-on time (p [de

    This study explored the relationship between intimate partner violence (IPV) and family planning among adolescent girls and young women in formal unions in the Philippines. Analyzing a sample (n =1,566) from the 2013 Philippines Demographic and Health Survey, logistic regression models were separately run for current contraception use and unmet need for family planning on recent physical violence (yes/no), recent sexual violence (yes/no), and recent emotional (yes/no). Findings revealed that the odds of using contraception were significantly higher among girls and young women who reported recent physical IPV (OR=1.84; 95% CI=1.13, 2.99; p<0.05) and sexual IPV (OR=2.18; 95% CI=1.17, 4.06; p<0.05). No significant relationship between recent emotional IPV and contraception use was found. Having an unmet need for family planning showed no significant relationship to IPV. The study adds to a growing body of literature revealing a positive association between IPV and contraception use. Findings hold implications for the provision of family planning services for adolescents and young women in response to the recent passage of landmark legislation pertaining to reproductive health in the Philippines, the Responsible Parenthood and Reproductive Health Act.

    Commissioning a new treatment planning system (TPS) involves many time-consuming tasks. We investigated the role that knowledge-based planning (KBP) can play in aiding a clinic's transition to a new TPS. Sixty clinically treated prostate/prostate bed intensity-modulated radiation therapy (IMRT) plans were exported from an in-house TPS and were used to create a KBP model in a newly implemented commercial application. To determine the benefit that KBP may have in a TPS transition, the model was tested on 2 groups of patients. Group 1 consisted of the first 10 prostate/prostate bed patients treated in the commercial TPS after the transition from the in-house TPS. Group 2 consisted of 10 patients planned in the commercial TPS after 8 months of clinical use. The KBP-generated plan was compared with the clinically used plan in terms of plan quality (ability to meet planning objectives and overall dose metrics) and planning efficiency (time required to generate clinically acceptable plans). The KBP-generated plans provided a significantly improved target coverage (p = 0.01) compared with the clinically used plans for Group 1, but yielded plans of comparable target coverage to the clinically used plans for Group 2. For the organs at risk, the KBP-generated plans produced lower doses, on average, for every normal-tissue objective except for the maximum dose to 0.1 cc of rectum. The time needed for the KBP-generated plans ranged from 6 to 15 minutes compared to 30 to 150 and 15 to 60 minutes for manual planning in Groups 1 and 2, respectively. KBP is a promising tool to aid in the transition to a new TPS. Our study indicates that high-quality treatment plans could have been generated in the newly implemented TPS more efficiently compared with not using KBP. Even after 8 months of the clinical use, KBP still showed an increase in plan quality and planning efficiency compared with manual planning.

    Teenage pregnancy is a signifi cant social issue in the United States, resulting in increased levels of poverty. Most public health family planning efforts have traditionally focused on teaching teens the how-to of contraception, with little focus on teaching the why-to. During my time as a nurse practitioner in a public health department family planning clinic, I developed a method to open discussions with patients about the possibilities of a future that includes delayed childbearing. My experience with this strategy taught me that hope may indeed be the most powerful contraceptive of all.

    Purpose: To prospectively determine whether overlap volume histogram (OVH)-driven, automated simultaneous integrated boosted (SIB)-intensity-modulated radiation therapy (IMRT) treatment planning for head-and-neck cancer can be implemented in clinics. Methods and Materials: A prospective study was designed to compare fully automated plans (APs) created by an OVH-driven, automated planning application with clinical plans (CPs) created by dosimetrists in a 3-dose-level (70 Gy, 63 Gy, and 58.1 Gy), head-and-neck SIB-IMRT planning. Because primary organ sparing (cord, brain, brainstem, mandible, and optic nerve/chiasm) always received the highest priority in clinical planning, the study aimed to show the noninferiority of APs with respect to PTV coverage and secondary organ sparing (parotid, brachial plexus, esophagus, larynx, inner ear, and oral mucosa). The sample size was determined a priori by a superiority hypothesis test that had 85% power to detect a 4% dose decrease in secondary organ sparing with a 2-sided alpha level of 0.05. A generalized estimating equation (GEE) regression model was used for statistical comparison. Results: Forty consecutive patients were accrued from July to December 2010. GEE analysis indicated that in APs, overall average dose to the secondary organs was reduced by 1.16 (95% CI = 0.09-2.33) with P=.04, overall average PTV coverage was increased by 0.26% (95% CI = 0.06-0.47) with P=.02 and overall average dose to the primary organs was reduced by 1.14 Gy (95% CI = 0.45-1.8) with P=.004. A physician determined that all APs could be delivered to patients, and APs were clinically superior in 27 of 40 cases. Conclusions: The application can be implemented in clinics as a fast, reliable, and consistent way of generating plans that need only minor adjustments to meet specific clinical needs.

    Family formation changed dramatically over the twentieth century in the United States. The impact of these changes on childbearing has primarily been studied in terms of nonmarital fertility. However, changes in family formation behavior also have implications for fertility within marriage. We use data from ten fertility surveys to describe changes in the timing of marital childbearing from the 1940s through the 21st century for non-Hispanic white and non-Hispanic black women. Based on harmonized data from the Integrated Fertility Survey Series, our results suggest increasing divergence in fertility timing for white women. A growing proportion of marriages begin with a premarital conception; at the same time, an increasing proportion of white women are postponing fertility within marriage. For black women, marital fertility is increasingly postponed beyond the early years of marriage. Evaluating the sequencing of marriage and parenthood over time is critical to understanding the changing meaning of marriage. PMID:24791019

    Advances in human health require the efficient and rapid translation of scientific discoveries into effective clinical treatments; this process in turn depends upon observational data gathered from patients, communities, and public-health research that can be used to guide basic scientific investigation. Such bidirectional translational science, however, faces unprecedented challenges due to the rapid pace of scientific and technological development, as well as the difficulties of negotiating increasingly complex regulatory and commercial environments that overlap the research domain. Further, numerous barriers to translational science have emerged among the nation’s academic research centers, including basic structural and cultural impediments to innovation and collaboration, shortages of trained investigators, and inadequate funding. To address these serious and systemic problems, in 2006, the National Institutes of Health created the Clinical and Translational Science Awards (CTSA) program, which aims to catalyze the transformation of biomedical research at a national level, speeding the discovery and development of therapies, fostering collaboration, engaging communities, and training succeeding generations of clinical and translational researchers. The authors report in detail on the planning process, begun in 2008, that was used to engage stakeholders and to identify, refine, and ultimately implement the CTSA program’s overarching strategic goals. They also discuss the implications and likely impact of this strategic planning process as it is applied among the nation’s academic health centers. PMID:20182119

    Full Text Available Dentofacial deformities (DFD presenting mainly as Class III malocclusions that require orthognathic surgery as a part of definitive treatment. Class III patients can have obvious signs such as increasing the chin projection and chin throat length, nasolabial folds, reverse overjet, and lack of upper lip support. However, Class III patients can present different facial patterns depending on the angulation of occlusal plane (OP, and only bite correction does not always lead to the improvement of the facial esthetic. We described two Class III patients with different clinical features and inclination of OP and had undergone different treatment planning based on 6 clinical features: (I facial type; (II upper incisor display at rest; (III dental and gingival display on smile; (IV soft tissue support; (V chin projection; and (VI lower lip projection. These patients were submitted to orthognathic surgery with different treatment plannings: a clockwise rotation and counterclockwise rotation of OP according to their facial features. The clinical features and OP inclination helped to define treatment planning by clockwise and counterclockwise rotations of the maxillomandibular complex, and two patients undergone to bimaxillary orthognathic surgery showed harmonic outcomes and stables after 2 years of follow-up.

    Purpose: To describe treatment planning techniques and early clinical outcomes in patients treated with spot scanning proton therapy for chordoma or chondrosarcoma of the skull base. Methods and Materials: From June 2010 through August 2011, 15 patients were treated with spot scanning proton therapy for chordoma (n=10) or chondrosarcoma (n=5) at a single institution. Toxicity was prospectively evaluated and scored weekly and at all follow-up visits according to Common Terminology Criteria for Adverse Events, version 3.0. Treatment planning techniques and dosimetric data were recorded and compared with those of passive scattering plans created with clinically applicable dose constraints. Results: Ten patients were treated with single-field-optimized scanning beam plans and 5 with multifield-optimized intensity modulated proton therapy. All but 2 patients received a simultaneous integrated boost as well. The mean prescribed radiation doses were 69.8 Gy (relative biological effectiveness [RBE]; range, 68-70 Gy [RBE]) for chordoma and 68.4 Gy (RBE) (range, 66-70) for chondrosarcoma. In comparison with passive scattering plans, spot scanning plans demonstrated improved high-dose conformality and sparing of temporal lobes and brainstem. Clinically, the most common acute toxicities included fatigue (grade 2 for 2 patients, grade 1 for 8 patients) and nausea (grade 2 for 2 patients, grade 1 for 6 patients). No toxicities of grades 3 to 5 were recorded. At a median follow-up time of 27 months (range, 13-42 months), 1 patient had experienced local recurrence and a second developed distant metastatic disease. Two patients had magnetic resonance imaging-documented temporal lobe changes, and a third patient developed facial numbness. No other subacute or late effects were recorded. Conclusions: In comparison to passive scattering, treatment plans for spot scanning proton therapy displayed improved high-dose conformality. Clinically, the treatment was well tolerated, and

    Willingness to engage in sustainable actions may be limited by the psychological distance of climate change. In this study, we test the legacy hypothesis , which holds that having children leads parents to consider the legacy left to offspring in respect of environmental quality. Using the Understanding Society dataset, a longitudinal survey representative of the UK population ( n  = 18,176), we assess how having children may change people's individual environmental attitudes and behaviour. Results indicate that having a new child is associated with a small decrease in the frequency of a few environmental behaviours. Only parents with already high environmental concern show a small increase in the desire to act more sustainably after the birth of their first child. Overall, the results do not provide evidence in support of the legacy hypothesis in terms of individual-level environmental attitudes and behaviours. We argue that the transition to parenthood is a time where concern is prioritised on the immediate wellbeing of the child and not on the future environmental threats.

    Purpose: To extend a clinical Record and Verify (R&V) system to enable a safe and fast workflow for Plan-of-the-Day (PotD) adaptive treatments based on patient-specific plan libraries. Methods: Plan libraries for PotD adaptive treatments contain for each patient several pre-treatment generated treatment plans. They may be generated for various patient anatomies or CTV-PTV margins. For each fraction, a Cone Beam CT scan is acquired to support the selection of the plan that best fits the patient’s anatomy-of-the-day. To date, there are no commercial R&V systems that support PotD delivery strategies. Consequently, the clinical workflow requires many manual interventions. Moreover, multiple scheduled plans have a high risk of excessive dose delivery. In this work we extended a commercial R&V system (MOSAIQ) to support PotD workflows using IQ-scripting. The PotD workflow was designed after extensive risk analysis of the manual procedure, and all identified risks were incorporated as logical checks. Results: All manual PotD activities were automated. The workflow first identifies if the patient is scheduled for PotD, then performs safety checks, and continues to treatment plan selection only if no issues were found. The user selects the plan to deliver from a list of candidate plans. After plan selection, the workflow makes the treatment fields of the selected plan available for delivery by adding them to the treatment calendar. Finally, control is returned to the R&V system to commence treatment. Additional logic was added to incorporate off-line changes such as updating the plan library. After extensive testing including treatment fraction interrupts and plan-library updates during the treatment course, the workflow is running successfully in a clinical pilot, in which 35 patients have been treated since October 2014. Conclusion: We have extended a commercial R&V system for improved safety and efficiency in library-based adaptive strategies enabling a wide

    Purpose: To extend a clinical Record and Verify (R&V) system to enable a safe and fast workflow for Plan-of-the-Day (PotD) adaptive treatments based on patient-specific plan libraries. Methods: Plan libraries for PotD adaptive treatments contain for each patient several pre-treatment generated treatment plans. They may be generated for various patient anatomies or CTV-PTV margins. For each fraction, a Cone Beam CT scan is acquired to support the selection of the plan that best fits the patient’s anatomy-of-the-day. To date, there are no commercial R&V systems that support PotD delivery strategies. Consequently, the clinical workflow requires many manual interventions. Moreover, multiple scheduled plans have a high risk of excessive dose delivery. In this work we extended a commercial R&V system (MOSAIQ) to support PotD workflows using IQ-scripting. The PotD workflow was designed after extensive risk analysis of the manual procedure, and all identified risks were incorporated as logical checks. Results: All manual PotD activities were automated. The workflow first identifies if the patient is scheduled for PotD, then performs safety checks, and continues to treatment plan selection only if no issues were found. The user selects the plan to deliver from a list of candidate plans. After plan selection, the workflow makes the treatment fields of the selected plan available for delivery by adding them to the treatment calendar. Finally, control is returned to the R&V system to commence treatment. Additional logic was added to incorporate off-line changes such as updating the plan library. After extensive testing including treatment fraction interrupts and plan-library updates during the treatment course, the workflow is running successfully in a clinical pilot, in which 35 patients have been treated since October 2014. Conclusion: We have extended a commercial R&V system for improved safety and efficiency in library-based adaptive strategies enabling a wide

    The Supreme Judicial Court of Massachusetts sustained a state statute which required pregnant unmarried minors to obtain the consent of both parents or a judge of the Superior Court in order to have an abortion. The court held that the state's interest in protecting the welfare of its minors and ensuring informed consent justified restrictions on a minor's constitutional right to choose an abortion. The court held unconstitutional, however, the law's requirement that the minor obtain the consent of both parents as an undue burden on the minor's due process rights.

    In September 1976 the Africa Regional Council (ARC) of IPPF created a Law Panel to 1) advise the ARC on the emphasis of laws and parenthood programs in the region, 2) investigate legal obstacles to family planning and ways of removing them, 3) institute a monitoring service on laws and court decisions affecting planned parenthood, and 4) prepare a list of lawyers and legal reformers by country. The panel has 1) recommended adoption of an IPPF Central Medical Committee and Central Law Panel statement on sterilization, adolescent fertility control, and the use of medical and auxiliary personnel in family planning services with guidelines for Africa; 2) appointed National Legal Correspondents to carry on the monitoring service mentioned above in 18 countries; and 3) discussed solutions to problems in delivering family planning services with family planning associations in Tanzania, Zambia, Mauritius, Madagascar, and Kenya. Laws governing family planning education and services, marriage, divorce, and maternity benefits in these countries are summarized. In 1978 the panel will hold 2 workshops on law and the status of women.

    Purpose: To demonstrate an efficient method for training and validation of a knowledge-based planning (KBP) system as a radiation therapy clinical trial plan quality-control system. Methods and Materials: We analyzed 86 patients with stage IB through IVA cervical cancer treated with intensity modulated radiation therapy at 2 institutions according to the standards of the INTERTECC (International Evaluation of Radiotherapy Technology Effectiveness in Cervical Cancer, National Clinical Trials Network identifier: 01554397) protocol. The protocol used a planning target volume and 2 primary organs at risk: pelvic bone marrow (PBM) and bowel. Secondary organs at risk were rectum and bladder. Initial unfiltered dose-volume histogram (DVH) estimation models were trained using all 86 plans. Refined training sets were created by removing sub-optimal plans from the unfiltered sample, and DVH estimation models… and DVH estimation models were constructed by identifying 30 of 86 plans emphasizing PBM sparing (comparing protocol-specified dosimetric cutpoints V{sub 10} (percentage volume of PBM receiving at least 10 Gy dose) and V{sub 20} (percentage volume of PBM receiving at least 20 Gy dose) with unfiltered predictions) and another 30 of 86 plans emphasizing bowel sparing (comparing V{sub 40} (absolute volume of bowel receiving at least 40 Gy dose) and V{sub 45} (absolute volume of bowel receiving at least 45 Gy dose), 9 in common with the PBM set). To obtain deliverable KBP plans, refined models must inform patient-specific optimization objectives and/or priorities (an auto-planning “routine”). Four candidate routines emphasizing different tradeoffs were composed, and a script was developed to automatically re-plan multiple patients with each routine. After selection of the routine that best met protocol objectives in the 51-patient training sample (KBP{sub FINAL}), protocol-specific DVH metrics and normal tissue complication probability were compared for original

    Research studies and popular accounts of parenting have documented the joys and strains of raising children. Much of the literature comparing parents with those without children indicates a happiness advantage for those without children, although recent studies have unpacked this general advantage to reveal differences by the dimension of well-being considered and important features in parents' lives and parenting experiences. We use unique data from the 2010, 2012, and 2013 American Time Use Survey to understand emotions in mothering experiences and how these vary by key demographic factors: employment and partnership status. Assessing mothers' emotions in a broad set of parenting activities while controlling for a rich set of person- and activity-level factors, we find that mothering experiences are generally associated with high levels of emotional well-being, although single parenthood is associated with differences in the emotional valence. Single mothers report less happiness and more sadness, stress, and fatigue in parenting than partnered mothers, and these reports are concentrated among those single mothers who are not employed. Employed single mothers are happier and less sad and stressed when parenting than single mothers who are not employed. Contrary to common assumptions about maternal employment, we find overall few negative associations between employment and mothers' feelings regarding time with children, with the exception that employed mothers report more fatigue in parenting than those who are not employed.

    Purpose: To develop a quality control tool to reduce stereotactic radiosurgery (SRS) planning variability using models that predict achievable plan quality metrics (QMs) based on individual patient anatomy. Methods: Using a knowledge-based methodology that quantitatively correlates anatomical geometric features to resultant organ-at-risk (OAR) dosimetry, we developed models for predicting achievable OAR dose-volume histograms (DVHs) by training with a cohort of previously treated SRS patients. The DVH-based QMs used in this work are the gradient measure, GM=(3/4pi)^1/3*[V50%^1/3−V100%^1/3], and V10Gy of normal brain. As GM quantifies the total rate of dose fall-off around the planning target volume (PTV), all voxels inside the patient's body contour were treated as OAR for DVH prediction. 35 previously treated SRS plans from our institution were collected; all were planned with non-coplanar volumetric-modulated arc therapy to prescription doses of 12–25 Gy. Of the 35-patient cohort, 15 were used for model training and 20 for model validation. Accuracies of the predictions were quantified by the mean and the standard deviation of the difference between clinical and predicted QMs, δQM=QM-clin−QM-pred. Results: Best agreement between predicted and clinical QMs was obtained when models were built separately for V-PTV<2.5cc and V-PTV>2.5cc. Eight patients trained the V-PTV<2.5cc model and seven patients trained the V-PTV>2.5cc models, respectively. The mean and the standard deviation of δGM were 0.3±0.4mm for the training sets and −0.1±0.6mm for the validation sets, demonstrating highly accurate GM predictions. V10Gy predictions were also highly accurate, with δV10Gy=0.8±0.7cc for the training sets and δV10Gy=0.7±1.4cc for the validation sets. Conclusion: The accuracy of the models in predicting two key SRS quality metrics highlights the potential of this technique for quality control for SRS treatments. Future investigations will seek to determine

    Despite a large body of research on planning performance in adult schizophrenia patients, results of individual studies are equivocal, suggesting either no, moderate or severe planning deficits. This meta-analysis therefore aimed to quantify planning deficits in schizophrenia and to examine potential sources of the heterogeneity seen in the literature. The meta-analysis comprised outcomes of planning accuracy of 1377 schizophrenia patients and 1477 healthy controls from 31 different studies which assessed planning performance using tower tasks such as the Tower of London, the Tower of Hanoi and the Stockings of Cambridge. A meta-regression analysis was applied to assess the influence of potential moderator variables (i.e. sociodemographic and clinical variables as well as task difficulty). The findings indeed demonstrated a planning deficit in schizophrenia patients (mean effect size: ; 95% confidence interval 0.56-0.78) that was moderated by task difficulty in terms of the minimum number of moves required for a solution. The results did not reveal any significant relationship between the extent of planning deficits and sociodemographic or clinical variables. The current results provide first meta-analytic evidence for the commonly assumed impairments of planning performance in schizophrenia. Deficits are more likely to become manifest in problem items with higher demands on planning ahead, which may at least partly explain the heterogeneity of previous findings. As only a small fraction of studies reported coherent information on sample characteristics, future meta-analyses would benefit from more systematic reports on those variables.

    Purpose: To perform an intracavitary radiotherapy (ICR) plan comparison between the conventional point A plan (conventional plan) and computed tomography (CT)-guided clinical target volume-based plan (CTV plan) by analysis of the quantitative dose-volume parameters and irradiated volumes of organs at risk in patients with cervical cancer. Methods and Materials: Thirty plans for 192 Ir high-dose-rate ICR after 30-40-Gy external beam radiotherapy were investigated. CT images were acquired at the first ICR session with artifact-free applicators in place. The gross tumor volume, clinical target volume (CTV), point A, and International Commission on Radiation Units and Measurements Report 38 rectal and bladder points were defined on reconstructed CT images. A fractional 100% dose was prescribed to point A in the conventional plan and to the outermost point to cover all CTVs in the CTV plan. The reference volume receiving 100% of the prescribed dose (V ref ), and the dose-volume parameters of the coverage index, conformal index, and external volume index were calculated from the dose-volume histogram. The bladder, rectal point doses, and percentage of volumes receiving 50%, 80%, and 100% of the prescribed dose were also analyzed. Results: Conventional plans were performed, and patients were categorized on the basis of whether the 100% isodose line of point A prescription dose fully encompassed the CTV (Group 1, n = 20) or not (Group 2, n = 10). The mean gross tumor volume (11.6 cm 3 ) and CTV (24.9 cm 3 ) of Group 1 were smaller than the corresponding values (23.7 and 44.7 cm 3 , respectively) for Group 2 (p = 0.003). The mean V ref for all patients was 129.6 cm 3 for the conventional plan and 97.0 cm 3 for the CTV plan (p = 0.003). The mean V ref in Group 1 decreased markedly with the CTV plan (p < 0.001). For the conventional and CTV plans in all patients, the mean coverage index, conformal index, and external volume index were 0.98 and 1.0, 0.23 and 0.34, and 3.86 and

    Aims To evaluate differences in the time taken to access progestogen-only emergency hormonal contraception (EHC) by young women from family planning (FP) or community pharmacy settings. Methods An observational study of 203 women requesting EHC from FP clinics and community pharmacies in South-west Kent Primary Care Trust (PCT) from December 2002 to October 2003. Results Access to EHC from community pharmacy was significantly faster than from FP clinics (16 h vs. 41 h, P < 0.001). Older teenagers tended to seek EHC more quickly and were more likely to have had a contraceptive failure rather than have used no contraception at all. Conclusion The results provide further support for pharmacist involvement in the supply of EHC. PMID:16669854

    In Brazil the private health plans appear as an alternative to the public health assistance. This segment suffered great intensification in the seventies and eighties, culminating in the entry of large insurance company in the scenario of supplementary medicine. Quickly, the service providers associated with these insurance companies, consolidating them in the market and triggering a relationship of dependency. This article analyzed, in the form of a case report, a marketing dispute between clinical laboratories and a health plan, emphasizing the moral and ethical aspects involved in this episode.

    Aim: Contemporary radiotherapy clinical trials typically require complex three-dimensional (3D) treatment planning. This produces large amounts of data relating technique and dose delivery for correlation with patient outcomes. Assessment of the quality of this information is required to ensure protocol compliance, to quantify the variation in treatments given to patients and to enhance the power of studies to determine correlates of patient outcomes. Materials and methods: A software system ('SWAN') was developed to facilitate the objective analysis, quality-assurance and review of digital treatment planning data from multi-centre radiotherapy trials. The utility of this system was assessed on the basis of its functionality and our experience of its use in the context of multi-centre clinical trials and trials-support activities. Results: The SWAN system has been shown to have the functionality required for use in several multi-centre trials, including automated review and archive processes. Approximately 800 treatment plans from over 30 participating institutions have so far been assessed with the system for several treatment planning scenarios. To illustrate this we include a description of the use of the system for a large-recruitment prostate radiotherapy trial being undertaken in Australasia, including examples of how the review process has changed clinical practice. Conclusion: The successful implementation of SWAN has been demonstrated in a number of clinical trials. The software provides an opportunity for comprehensive review of treatment parameters that could impact on clinical outcomes and trial results. Such quality-assurance (QA) has previously been difficult or impossible to achieve, particularly for a clinical trial involving large numbers of patients. Such reviews have highlighted inconsistencies in clinical practice that have since been addressed through feedback from the review process. The process of data collection and review should be

    Purpose: To report the dosimetric outcome of patients with clinically localized prostate cancer treated with I-125 permanent implantation using an intraoperative real-time conformal planning technique. Methods and materials: Five hundred and sixty-two patients with prostate cancer were treated with I-125 permanent interstitial implantation using a transrectal ultrasound-guided approach. Real-time intraoperative treatment planning software that incorporates inverse planning optimization was used. Dose-volume constraints for this inverse-planning system included: prostate V100 ≥95%, maximal urethral dose ≤120%, and average rectal dose 3 of the rectum was exposed to the prescription dose, the incidence of late grade 2 toxicity rectal toxicity was 9% compared to 4% for smaller volumes of the rectum exposed to similar doses (p = 0.003). No dosimetric parameter in these patients with tight dose confines for the urethra influenced acute or late urinary toxicity. Conclusion: Real-time intraoperative planning was associated with a 90% consistency of achieving the planned intraoperative dose constraints for target coverage and maintaining planned urethral and rectal constraints in a high percentage of implants. Rectal volumes of ≥2.5 cm 3 exposed to the prescription doses were associated with an increased incidence of grade 2 rectal bleeding. Further enhancements in imaging guidance for optimal seed deposition are needed to guarantee optimal dose distribution for all patients. Whether such improvements lead to further reduction in acute and late morbidities associated with therapy requires further study

    Preoperative planning is of great importance for transforaminal endoscopic techniques applied in percutaneous endoscopic lumbar discectomy. In this study, a modular preoperative planning software for transforaminal endoscopic surgery was developed and demonstrated. The path searching method is based on collision detection, and the oriented bounding box was constructed for the anatomical models. Then, image reformatting algorithms were developed for multiplanar reconstruction which provides detailed anatomical information surrounding the virtual planned path. Finally, multithread technique was implemented to realize the steady-state condition of the software. A preoperative planning software for transforaminal endoscopic surgery (TE-Guider) was developed; seven cases of patients with symptomatic lumbar disc herniations were planned preoperatively using TE-Guider. The distances to the midlines and the direction of the optimal paths were exported, and each result was in line with the empirical value. TE-Guider provides an efficient and cost-effective way to search the ideal path and entry point for the puncture. However, more clinical cases will be conducted to demonstrate its feasibility and reliability.

    Despite good contraceptive coverage rates, recent studies in Iran have shown an alarmingly high incidence of unplanned pregnancy. To determine factors affecting quality of family planning services, a cross-sectional study was performed from June to August 2006 on women visiting urban Primary Health Care clinics in a provincial capital in western Iran. The primary focus of the study was on provider-client interaction. We used a slightly edited version of a UNICEF checklist and a convenient sampling method to assess quality of care in 396 visits to the family planning sections at 25 delivery points. Poor performance was observed notably in Counselling and Choice of method sections. In logistic regression analysis, the following factors were found to be associated with higher quality of care: provider experience [OR (odds ratio)=1.9, CI(0.95) (confidence interval)=1.2-3.0], low provider education (OR=6.7, CI(0.95)=4.0-10.8), smaller workload at the clinic (OR=3.7, CI(0.95)=2.0-6.7), and 'new client' status (OR=4.2, CI(0.95)=2.6-6.7). This study identified the issues of counselling and information exchange as the quality domains in serious need of improvement; these areas are expected to be the focus of future training programmes for care providers. Also, priority should be given to devising effective supervision mechanisms and on-the-job training of senior nursing and midwifery graduates to make them more competent in delivering basic family planning services.

    The purpose of this investigation was to assess the balance between the personal and professional lives of trainees and young European specialists in clinical microbiology (CM) and infectious diseases (ID), and determine differences according to gender, country of training, workplace and specialty. The Steering Committee of the Trainee Association of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) devised a questionnaire survey consisting, beyond the demographic questions, of nine yes/no questions, 11 Likert scale self-evaluations and one open-response item on parenthood, working conditions, quality of life, alcohol consumption and burnout. This anonymous survey in English was held between April and July 2015 among European CM/ID trainees and young specialists (mothers enjoyed the benefit of working hours flexibility. Only two-thirds of respondents found their working environment stimulating. In comparison to colleagues from other parts of Europe, trainees and young specialists from Southern/Eastern Europe (SEE) had less frequent regular meetings with mentors/supervisors and head of departments where trainees' issues are discussed. Also, physicians from SEE were more frequently victims of workplace mobbing/bullying in comparison to those from other regions. Finally, multivariate analysis showed that female gender, SEE region and ID specialty were associated with burnout feelings. Female gender and country of work from SEE largely determine satisfactory working conditions, the possibility of parenthood leaves, amount of leisure time, mobbing experiences and burnout feelings among European CM/ID trainees and young specialists.

    There is a trend to delay birth of the first child until the age at which female reproductive capacity has started to decrease. The aim of the present study was to explore how highly educated women and men reflected on future parenthood. Twenty-two women and 18 men, who had started their professional career, were subjected to individual qualitative semi-structured interviews with qualitative content analysis guiding the analysis. All informants, except for three women, planned to have children when some important prerequisites were fulfilled. Women and men reflected in much the same way, and prerequisites for parenthood were being of reasonable age and having a partner in the same phase of life. A reasonable age was considered in relation to reproductive capacity, and both women and men expressed awareness of the natural decline in fertility at higher ages. Good living conditions with stable finances were also important. Parenthood was perceived as a challenge and a sacrifice but also as enriching life. Reasons for having children included being part of the future and settling down to build their own family. Many concluded that there would never be a perfect time for having children. Highly educated women and men reflect on various factors when considering family planning. Being of reasonable age and having good living conditions, in particular a sound personal economy, were important. Given their goals, it is not surprising that many postpone parenthood until ages when female reproductive capacity is decreased.

    Data management has significant impact on the quality control of clinical studies. Every clinical study should have a data management plan to provide overall work instructions and ensure that all of these tasks are completed according to the Good Clinical Data Management Practice (GCDMP). Meanwhile, the data management plan (DMP) is an auditable document requested by regulatory inspectors and must be written in a manner that is realistic and of high quality. The significance of DMP, the minimum standards and the best practices provided by GCDMP, the main contents of DMP based on electronic data capture (EDC) and some key factors of DMP influencing the quality of clinical study were elaborated in this paper. Specifically, DMP generally consists of 15 parts, namely, the approval page, the protocol summary, role and training, timelines, database design, creation, maintenance and security, data entry, data validation, quality control and quality assurance, the management of external data, serious adverse event data reconciliation, coding, database lock, data management reports, the communication plan and the abbreviated terms. Among them, the following three parts are regarded as the key factors: designing a standardized database of the clinical study, entering data in time and cleansing data efficiently. In the last part of this article, the authors also analyzed the problems in clinical research of traditional Chinese medicine using the EDC system and put forward some suggestions for improvement.

    2014-11-01

    Purpose: To evaluate the clinical implementation of an online adaptive plan-of-the-day protocol for nonrigid target motion management in locally advanced cervical cancer intensity modulated radiation therapy (IMRT). Methods and Materials: Each of the 64 patients had four markers implanted in the vaginal fornix to verify the position of the cervix during treatment. Full and empty bladder computed tomography (CT) scans were acquired prior to treatment to build a bladder volume-dependent cervix-uterus motion model for establishment of the plan library. In the first phase of clinical implementation, the library consisted of one IMRT plan based on a single model-predicted internal target volume (mpITV), covering the target for the whole pretreatment observed bladder volume range, and a 3D conformal radiation therapy (3DCRT) motion-robust backup plan based on the same mpITV. The planning target volume (PTV) combined the ITV and nodal clinical target volume (CTV), expanded with a 1-cm margin. In the second phase, for patients showing >2.5-cm bladder-induced cervix-uterus motion during planning, two IMRT plans were constructed, based on mpITVs for empty-to-half-full and half-full-to-full bladder. In both phases, a daily cone beam CT (CBCT) scan was acquired to first position the patient based on bony anatomy and nodal targets and then select the appropriate plan. Daily post-treatment CBCT was used to verify plan selection. Results: Twenty-four and 40 patients were included in the first and second phase, respectively. In the second phase, 11 patients had two IMRT plans. Overall, an IMRT plan was used in 82.4% of fractions. The main reasons for selecting the motion-robust backup plan were uterus outside the PTV (27.5%) and markers outside their margin (21.3%). In patients with two IMRT plans, the half-full-to-full bladder plan was selected on average in 45% of the first 12 fractions, which was reduced to 35% in the last treatment fractions. Conclusions: The implemented

    Purpose: Pencil-beam or superposition-convolution type dose calculation algorithms are routinely used in inverse plan optimization for intensity modulated radiation therapy (IMRT). However, due to their limited accuracy in some challenging cases, e.g. lung, the resulting dose may lose its optimality after being recomputed using an accurate algorithm, e.g. Monte Carlo (MC). It is the objective of this study to evaluate the feasibility and advantages of a new method to include MC in the treatment planning process. Methods: We developed a scheme to iteratively perform MC-based beamlet dose calculations and plan optimization. In the MC stage, a GPU-based dose engine was used and the particle number sampled from a beamlet was proportional to its optimized fluence from the previous step. We tested this scheme in four lung cancer IMRT cases. For each case, the original plan dose, plan dose re-computed by MC, and dose optimized by our scheme were obtained. Clinically relevant dosimetric quantities in these three plans were compared. Results: Although the original plan achieved a satisfactory PDV dose coverage, after re-computing doses using MC method, it was found that the PTV D95% were reduced by 4.60%–6.67%. After re-optimizing these cases with our scheme, the PTV coverage was improved to the same level as in the original plan, while the critical OAR coverages were maintained to clinically acceptable levels. Regarding the computation time, it took on average 144 sec per case using only one GPU card, including both MC-based beamlet dose calculation and treatment plan optimization. Conclusion: The achieved dosimetric gains and high computational efficiency indicate the feasibility and advantages of the proposed MC-based IMRT optimization method. Comprehensive validations in more patient cases are in progress.

    Secondary use of clinical routine data is receiving an increasing amount of attention in biomedicine and healthcare. However, building and analysing integrated clinical routine data repositories are nontrivial, challenging tasks. As in most evolving fields, recognized standards, well-proven methodological frameworks, or accurately described best-practice approaches for the systematic planning of solutions for secondary use of routine medical record data are missing. We propose a conceptual best-practice framework and procedure model for the systematic planning of intelligent reuse of integrated clinical routine data (SPIRIT). SPIRIT was developed based on a broad literature overview and further refined in two case studies with different kinds of clinical routine data, including process-oriented nursing data from a large hospital group and high-volume multimodal clinical data from a neurologic intensive care unit. SPIRIT aims at tailoring secondary use solutions to specific needs of single departments without losing sight of the institution as a whole. It provides a general conceptual best-practice framework consisting of three parts: First, a secondary use strategy for the whole organization is determined. Second, comprehensive analyses are conducted from two different viewpoints to define the requirements regarding a clinical routine data reuse solution at the system level from the data perspective (BOTTOM UP) and at the strategic level from the future users perspective (TOP DOWN). An obligatory clinical context analysis (IN BETWEEN) facilitates refinement, combination, and integration of the different requirements. The third part of SPIRIT is dedicated to implementation, which comprises design and realization of clinical data integration and management as well as data analysis solutions. The SPIRIT framework is intended to be used to systematically plan the intelligent reuse of clinical routine data for multiple purposes, which often was not intended when the

    Purpose: Peer review is a recommended component of quality assurance in radiation oncology; however, it is resource-intensive and its effect on patient care is not well understood. We conducted a systematic review of the published data to assess the reported clinical impact of peer review on radiation treatment plans. Methods and Materials: A systematic review of published English studies was performed in accordance with the PRISMA guidelines using the MEDLINE and EMBASE databases and abstracts published from major radiation oncology scientific meeting proceedings. For inclusion, the studies were required to report the effect of peer review on ≥1 element of treatment planning (eg, target volume or organ-at-risk delineation, dose prescription or dosimetry). Results: The initial search strategy identified 882 potentially eligible studies, with 11 meeting the inclusion criteria for full-text review and final analysis. Across a total of 11,491 patient cases, peer review programs led to modifications in a weighted mean of 10.8% of radiation treatment plans. Five studies differentiated between major and minor changes and reported weighted mean rates of change of 1.8% and 7.3%, respectively. The most common changes were related to target volume delineation (45.2% of changed plans), dose prescription or written directives (24.4%), and non-target volume delineation or normal tissue sparing (7.5%). Conclusions: Our findings suggest that peer review leads to changes in clinical care in approximately 1 of every 9 cases overall. This is similar to the reported rates of change in peer review studies from other oncology-related specialties, such as radiology and pathology.

    Drawing from queer and communication privacy management frameworks, this study examines the narratives of 22 bisexual, male-partnered women who were interviewed during the perinatal period and one year postnatally about their disclosures of sexual identity to family of origin. Most women rarely discussed their sexual identity with family; participants who had disclosed described such disclosures as provoking discomfort. Some women stated that their parental status seemed to invalidate the need to talk about their sexual history or identity with family, due its declining salience and increased concerns about judgment. This study reveals how partnership and parenthood statuses contribute to the intensification of heteronormative pressures in relation to family. Therapists should attend to the role of heteronormative values regarding partnering, family-building, and parenting. © 2017 American Association for Marriage and Family Therapy.

    Recently, precision irradiators integrated with a high-resolution CT imaging device became available for pre-clinical studies. These research platforms offer significant advantages over older generations of animal irradiators in terms of precision and accuracy of image-guided radiation targeting. These platforms are expected to play a significant role in defining experiments that will allow translation of research findings to the human clinical setting. In the field of radiotherapy, but also others such as neurology, the platforms create unique opportunities to explore e.g. the synergy between radiation and drugs or other agents. To fully exploit the advantages of this new technology, accurate methods are needed to plan the irradiation and to calculate the three-dimensional radiation dose distribution in the specimen. To this end, dedicated treatment planning systems are needed. In this review we will discuss specific issues for precision irradiation of small animals, we will describe the workflow of animal treatment planning, and we will examine several dose calculation algorithms (factorization, superposition-convolution, Monte Carlo simulation) used for animal irradiation with kilovolt photon beams. Issues such as dose reporting methods, photon scatter, tissue segmentation and motion will also be discussed briefly.

    Parent-child relationship is created already in prenatal fantasies and expectations of the child-to-be. Negative violation of these expectations after the child is born is known to be harmful for the parent-child relationship. Yet, research is scarce about the medical and psychological factors contributing to violated expectations (VE). This study models the role of parent-, delivery- and infant-related underlying mechanisms for VE. It further compares parents with assisted reproductive treatment (ART) and spontaneous conception (SC), and primi- and multiparous couples. The couples (n = 743) separately filled in questionnaires concerning their prenatal expectations (T1) and 2 months postnatal representations (T2) of intimacy and autonomy in the relationship with their child, measured with Subjective Family Picture Test. A negative or positive discrepancy indicated violated expectations. The parent-related (mental health and marital quality), delivery-related (maternal and paternal birth experience, unplanned Caesarean, and amount of analgesia) and infant-related (infant health problems, difficult infant characteristics, and parental worry) factors were assessed at T2. Results show that among mothers, the associations were mostly indirect and mediated via mental health problems. Among fathers, the associations were direct, marital problems most crucially predicting VE. ART fathers were less susceptible to VE resulting from infant-related problems than SC fathers, but more susceptible to VE resulting from delivery problems. Delivery- and infant-related factors also predicted VE differently among primi- and multiparous mothers. Considering factors that contribute to VE is important when working with couples in transition to parenthood. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    Decades of social change in West Germany and the emergence of an ideology that stresses individualism have altered dramatically procreative behavioral patterns. At present, West Germany is characterized by a low marriage rate (6.1/1000 in 1986), declining fertility (10.3 birth/1000), rising divorce rates (20.1/1000), and increases in the proportion of single-person households (34%). The relationship between family planning, family policy, and demographic policy is unclear and changing. Family planning practice is viewed as a part of comprehensive life planning and is based on factors such as partnership or marital status, sex roles, the conflict between working in the home and having a career, consumer aspirations, and housing conditions. The Government's family policy includes the following components: child benefits, tax relief on children, tax splitting arrangements for married couples, childcare allowance, parental leave, student grants, tax deductions for domiciliary professional help and nursing assistance, and the provision of daycare. Thus, West Germany's family policy is directed more at encouraging and facilitating parenthood and family life than at a setting demographic goals. There is no evidence, however, that such measures will be successful and divergent influences of other policy areas are often more compelling. Nor is there any way to quantify the fertility-costing impact of individual family policy measures. The indistinct nature of family planning policy in West Germany mirrors political differences between the current coalition government, which maintains a traditional view of the family, and the opposition Social-Democratic and Green Parties, which question whether the equality of men and women can be achieved in the context of old family structures.

    While women continue to enter the American work force in record numbers; many experience difficulty in juggling career and family obligations. Flexible scheduling is one option used to ease work and family pressures. Women's changing work roles have potentially noteworthy implications for clinical nutrition management, a traditionally female-dominated profession where the recruitment and retention of valued, experienced registered dietitians can prove to be a human resources challenge. Job sharing, one type of flexible scheduling, is applicable to the nutrition management arena. This article describes and offers a plan for overcoming obstacles to job sharing, including determining feasibility, gaining support of top management, establishing program design, announcing the job share program, and using implementation, monitoring, and fine-tuning strategies. Benefits that can be derived from a successful job share are reduced absenteeism, decreased turnover, enhanced recruitment, improved morale, increased productivity, improved job coverage, and enhanced skills and knowledge base. A case study illustrates one method for achieving job sharing success in clinical nutrition management.

    Based on experiences with the Productive Cooperative Movement and the Parasite Control Movement in Japan, the Japanese Family Planning Movement began in April 1954. The resultant private and nonprofit Japan Family Planning Association (JFPA) followed and it served to help Japan achieve its goal of reducing fertility by promoting family planning. It did so by publishing a monthly newsletter on family planning, hosting meetings and national conventions, spreading information via the mass media, and selling contraceptives and educational materials. JFPA earned funding from these sales with no support from the government thereby establishing self dependence and freedom to speak candidly to the government. The JFPA learned that families wanted to improve their standard of living and were willing to limit family size to 2 children. After the birth rate peaked in 1955, the birth rate and the number of illegal abortions decreased. In the 1950s, JFPA joined the International Planned Parenthood Federation and subsequently learned of the problems faced by developing countries. Based on the successful reduction of fertility in Japan and a strong economic base, JFPA and the government were in a position to organize an international cooperation program for family planning. Therefore, the leader of JFPA resigned to found the Japanese Organization for International Cooperation in Family Planning which promotes family planning in developing countries via its integrated family planning, nutrition, and parasite control program. A steering committee composed of leaders from government, universities, and private organizations sets the policies for the program in each country. It is to the Japanese government's advantage to work with private organizations instead of providing all social services because they are flexible and provide administrative stability and national expenses are minimized.

    The development of hyperthermia, the treatment of tumours with elevated temperatures in the range of 40-44 deg. C with treatment times over 30 min, greatly benefits from the development of hyperthermia treatment planning. This review briefly describes the state of the art in hyperthermia technology, followed by an overview of the developments in hyperthermia treatment planning. It particularly highlights the significant problems encountered with heating realistic tissue volumes and shows how treatment planning can help in designing better heating technology. Hyperthermia treatment planning will ultimately provide information about the actual temperature distributions obtained and thus the tumour control probabilities to be expected. This will improve our understanding of the present clinical results of thermoradiotherapy and thermochemotherapy, and will greatly help both in optimizing clinical heating technology and in designing optimal clinical trials.

    Intensity-modulated radiation therapy (IMRT) has become a standard technique in radiation therapy for treating different types of cancers. Various class solutions have been developed for simple cases (e.g., localized prostate, whole breast) to generate IMRT plans efficiently. However, for more complex cases (e.g., head and neck, pelvic nodes), it can be time-consuming for a planner to generate optimized IMRT plans. To generate optimal plans in these more complex cases which generally have multiple target volumes and organs at risk, it is often required to have additional IMRT optimization structures such as dose limiting ring structures, adjust beam geometry, select inverse planning objectives and associated weights, and additional IMRT objectives to reduce cold and hot spots in the dose distribution. These parameters are generally manually adjusted with a repeated trial and error approach during the optimization process. To improve IMRT planning efficiency in these more complex cases, an iterative method that incorporates some of these adjustment processes automatically in a planning script is designed, implemented, and validated. In particular, regional optimization has been implemented in an iterative way to reduce various hot or cold spots during the optimization process that begins with defining and automatic segmentation of hot and cold spots, introducing new objectives and their relative weights into inverse planning, and turn this into an iterative process with termination criteria. The method has been applied to three clinical sites: prostate with pelvic nodes, head and neck, and anal canal cancers, and has shown to reduce IMRT planning time significantly for clinical applications with improved plan quality. The IMRT planning scripts have been used for more than 500 clinical cases.

    Treatment planning in gynecologic cancer is a complicated and difficult procedure. It requires an adequate preoperative assessment of the true extent of the patient's disease process and oftentimes this can be achieved not only by conventional studies but must employ surgical exploratory techniques in order to truly define the extent of the disease. However, with contemporary sophisticated treatment planning techniques that are now available in most contemporary departments of radiation oncology, radiation therapy is reemerging as an important and major treatment technique in the management of patients with gynecologic cancer

    Full Text Available Introduction: Increasingly, pediatric and emergency medicine (EM residents are pursuing clinical rotations in low-income countries. Optimal pre-departure preparation for such rotations has not yet been established. High-fidelity simulation represents a potentially effective modality for such preparation. This study was designed to assess whether a pre-departure high-fidelity medical simulation curriculum is effective in helping to prepare residents for clinical rotations in a low-income country. Methods: 43 pediatric and EM residents planning clinical rotations in Liberia, West Africa, participated in a simulation-based curriculum focused on severe pediatric malaria and malnutrition and were then assessed by survey at three time points: pre-simulation, post-simulation, and after returning from work abroad. Results: Prior to simulation, 1/43 (2% participants reported they were comfortable with the diagnosis and management of severe malnutrition; this increased to 30/42 (71% after simulation and 24/31 (77% after working abroad. Prior to simulation, 1/43 (2% of residents reported comfort with the diagnosis and management of severe malaria; this increased to 26/42 (62% after simulation and 28/31 (90% after working abroad; 36/42 (86% of residents agreed that a simulation-based global health curriculum is more useful than a didactic curriculum alone, and 41/42 (98% felt a simulator-based curriculum should be offered to all residents planning a clinical trip to a low-income country. Conclusion: High-fidelity simulation is effective in increasing residents’ self-rated comfort in management of pediatric malaria and malnutrition and a majority of participating residents feel it should be included as a component of pre-departure training for all residents rotating clinically to low-income countries.

    Purpose: Medical training spans nearly a decade, during which many physicians traditionally begin families. Although childrearing responsibilities are shared by men and women in the modern era, differences in time allocated to child care by sex and its potential impact on residency experience merit discussion. Methods and Materials: An anonymous, voluntary, 102-item survey was distributed to 540 current radiation oncology residents and 2014 graduates that asked about marital and parental status, pregnancy during residency, publication productivity, career aspirations, and experiences working with pregnant co-residents. Respondents with children were asked about childcare arrangements, and women who were pregnant during residency were asked about radiation safety, maternity leave, and breastfeeding experiences. Results: A total of 190 respondents completed the survey, 107 men (56.3%) and 84 women (43.7%). Ninety-seven respondents (51.1%) were parents, and 84 (44.2%) reported a pregnancy during residency. Respondents with children more often were male (65% vs 47.3%; P=.014), in a higher level of training (79.3% vs 54.8% were PGY4 or higher; P=.001), were older (median age of 32, interquartile range [IQR]:31-35] vs age 30 [IQR: 29-33]; P<.001), had a PhD (33% vs 19.3%, respectively; P=.033), were married (99% vs 43%, respectively; P<.001), and had a partner who did not work (24.7% vs 1.9%, respectively; <.001). There were no differences in the number of manuscripts published or the number of residents who expressed likelihood of pursing an academic career by parental status. Among parents, men more frequently had partners who did not work (38.1% vs 0%, respectively; P<.001) and reported that their partner performed a greater percentage of childcare duties (70% [IQR: 60%-80%] vs 35% [IQR: 20%-50%], respectively; P<.001). Conclusions: Pregnancy and parenthood are common during residency. Female residents are frequently responsible for more childcare duties than males

    group-based antenatal care consists of six to nine two-hour sessions in which information is shared and discussed during the first hour and individual examinations are conducted during the second hour. Groups generally consist of six to eight pregnant women. Parent education is built into the programme, which originated in the United States and was introduced in Sweden at the beginning of the year of 2000. to investigate parents' experiences of group antenatal care in four different clinics in Sweden. a qualitative study was conducted using content analysis five group interviews and eleven individual interviews with parents who experienced group-based antenatal care. An interview guide was used. the study was set in four antenatal clinics that had offered group-based antenatal care for at least one year. The clinics were located in three different areas of Sweden. the participants were women and their partners who had experienced group-based antenatal care during pregnancy. Other criteria for participation were mastery of the Swedish language and having followed the care programme. three themes emerged, 'The care-combining individual physical needs with preparation for parenthood, refers to the context, organisation, and content of care'. Group antenatal care with inbuilt parent education was appreciated, but respondents reported that they felt unprepared for the first few weeks after birth. Their medical needs (for physical assessment and screening) were, however, fulfilled. The theme, 'The group-a composed recipient of care', showed the participants role and experience. The role could be passive or active in groups or described as sharers. Groups helped parents normalise their symptoms. The theme, 'The midwife-a controlling professional', showed midwives are ignorant of gender issues but, for their medical knowledge, viewed as respectable professionals. in the four clinics studied, group-based antenatal care appeared to meet parents' needs for physical assessment

    To optimize transportation processes, we present herein a contingency plan that coordinates interim measures used to ensure continued and timely services when climate based events might cause an interruption of the usual specimen transportation processes. As an example, we outline the implementation and effectiveness of a contingency plan for network laboratory courier automobile transportation during times of mountain pass highway closure. Data available from an approximately 3-year period from October 10, 2010 through August 29, 2013 revealed a total of 690 complete closures in the eastbound or westbound lanes of the Interstate-90 highway in the Snoqualmie Pass area in the state of Washington. Despite the frequency of closures, the Washington State Department of Transportation was effective in limiting the duration of closures. Road closures of less than 1 hour accounted for 58.7% of the total closures. No recorded closures prevented dispatched couriers from completing a prescheduled Snoqualmie Pass route. We identified no delays as being clinically significant, despite that there were 5 instances of delays greater than 4 hours. We implemented a contingency plan of aiding courier logistics during all times of pass closure. The plan includes an easy to interpret Condition Dashboard as a status indicator and a Decision Tree that references and summarizes information. Overall, the contingency plan allows for an objective, robust, proactive decision support system that has enabled operational flexibility and has contributed to continued safe, on-time specimen transportation; clients and courier and reference laboratory staff have appreciated these features and associated outcomes.

    A Standardized Clinical Assessment and Management Plan (SCAMP) is a novel quality improvement initiative that standardizes the assessment and management of all patients who carry a predefined diagnosis. Based on periodic review of systemically collected data the SCAMP is designed to be modified to improve its own algorithm. One of the objectives of a SCAMP is to identify and reduce resource utilization and patient care costs. We retrospectively reviewed resource utilization in the first 93 arterial switch operation (ASO) SCAMP patients and 186 age-matched control ASO patients. We compared diagnostic and laboratory testing obtained at the initial SCAMP clinic visit and control patient visits. To evaluate the effect of the SCAMP over time, the number of clinic visits per patient year and echocardiograms per patient year in historical control ASO patients were compared to the projected rates for ASO SCAMP participants. Cardiac magnetic resonance imaging (MRI), stress echocardiogram, and lipid profile utilization were higher in the initial SCAMP clinic visit group than in age-matched control patients. Total echocardiogram and lung scan usage were similar. Chest X-ray and exercise stress testing were obtained less in SCAMP patients. ASO SCAMP patients are projected to have 0.5 clinic visits and 0.5 echocardiograms per year. Historical control patients had more clinic visits (1.2 vs. 0.5 visits/patient year, P<.01) and a higher echocardiogram rate (0.92 vs. 0.5 echocardiograms/patient year, P<.01) Implementation of a SCAMP may initially lead to increased resource utilization, but over time resource utilization is projected to decrease.

    Purpose: Knowledge Based Radiation Therapy Treatment (KBRT) planning can be used to semi-automatically generate IMRT plans for new patients using constraints derived from previously manually-planned, geometrically similar patients. We investigate whether KBRT plans can achieve greater dose sparing than manual plans using optimized, organspecific constraint weighting factors. Methods: KBRT planning of HNC radiotherapy cases geometrically matched each new (query) case to one of the 105 clinically approved plans in our database. The dose distribution of the planned match was morphed to fit the querys geometry. Dose-volume constraints extracted from the morphed dose distribution were used to run the IMRT optimization with no user input. In the first version, all constraints were multiplied by a weighting factor of 0.7. The weighting factors were then systematically optimized (in order of OARs with increasing separation from the target) to maximize sparing to each OAR without compromising other OARs. The optimized, second version plans were compared against the first version plans and the clinically approved plans for 45 unilateral/bilateral target cases using the dose metrics: mean, median and maximum (brainstem and cord) doses. Results: Compared to the first version, the second version significantly reduced mean/median contralateral parotid doses (>2Gy) for bilateral cases. Other changes between the two versions were not clinically meaningful. Compared to the original clinical plans, both bilateral and unilateral plans in the second version had lower average dose metrics for 5 of the 6 OARs. Compared to the original plans, the second version achieved dose sparing that was at least as good for all OARs and better for the ipsilateral parotid (bilateral) and oral cavity (bilateral/unilateral). Differences in planning target volume coverage metrics were not clinically significant. Conclusion: HNC-KBRT planning generated IMRT plans with at least equivalent dose sparing to

    Purpose: Knowledge Based Radiation Therapy Treatment (KBRT) planning can be used to semi-automatically generate IMRT plans for new patients using constraints derived from previously manually-planned, geometrically similar patients. We investigate whether KBRT plans can achieve greater dose sparing than manual plans using optimized, organspecific constraint weighting factors. Methods: KBRT planning of HNC radiotherapy cases geometrically matched each new (query) case to one of the 105 clinically approved plans in our database. The dose distribution of the planned match was morphed to fit the querys geometry. Dose-volume constraints extracted from the morphed dose distribution were used to run the IMRT optimization with no user input. In the first version, all constraints were multiplied by a weighting factor of 0.7. The weighting factors were then systematically optimized (in order of OARs with increasing separation from the target) to maximize sparing to each OAR without compromising other OARs. The optimized, second version plans were compared against the first version plans and the clinically approved plans for 45 unilateral/bilateral target cases using the dose metrics: mean, median and maximum (brainstem and cord) doses. Results: Compared to the first version, the second version significantly reduced mean/median contralateral parotid doses (>2Gy) for bilateral cases. Other changes between the two versions were not clinically meaningful. Compared to the original clinical plans, both bilateral and unilateral plans in the second version had lower average dose metrics for 5 of the 6 OARs. Compared to the original plans, the second version achieved dose sparing that was at least as good for all OARs and better for the ipsilateral parotid (bilateral) and oral cavity (bilateral/unilateral). Differences in planning target volume coverage metrics were not clinically significant. Conclusion: HNC-KBRT planning generated IMRT plans with at least equivalent dose sparing to

    Background There is a trend to delay birth of the first child until the age at which female reproductive capacity has started to decrease. The aim of the present study was to explore how highly educated women and men reflected on future parenthood. Methods Twenty-two women and 18 men, who had started their professional career, were subjected to individual qualitative semi-structured interviews with qualitative content analysis guiding the analysis. Results All informants, except for three women, planned to have children when some important prerequisites were fulfilled. Women and men reflected in much the same way, and prerequisites for parenthood were being of reasonable age and having a partner in the same phase of life. A reasonable age was considered in relation to reproductive capacity, and both women and men expressed awareness of the natural decline in fertility at higher ages. Good living conditions with stable finances were also important. Parenthood was perceived as a challenge and a sacrifice but also as enriching life. Reasons for having children included being part of the future and settling down to build their own family. Many concluded that there would never be a perfect time for having children. Conclusion Highly educated women and men reflect on various factors when considering family planning. Being of reasonable age and having good living conditions, in particular a sound personal economy, were important. Given their goals, it is not surprising that many postpone parenthood until ages when female reproductive capacity is decreased. PMID:22300332

    Purpose: There is potentially a wide variation in plan quality for a certain disease site, even for clinics located in the same system of hospitals. We have used a prostate-specific knowledge-based planning (KBP) model as a quality control tool to investigate the variation in prostate treatment planning across a network of affiliated radiation oncology departments. Methods: A previously created KBP model was applied to 10 patients each from 4 community-based clinics (Clinics A, B, C, and D). The KBP model was developed using RapidPlan (Eclipse v13.5, Varian Medical Systems) from 60 prostate/prostate bed IMRT plans that were originally planned using an in-house treatment planning system at the central institution of the community-based clinics. The dosimetric plan quality (target coverage and normal-tissue sparing) of each model-generated plan was compared to the respective clinically-used plan. Each community-based clinic utilized the same planning goals to develop the clinically-used plans that were used at the main institution. Results: Across all 4 clinics, the model-generated plans decreased the mean dose to the rectum by varying amounts (on average, 12.5, 2.6, 4.5, and 2.7 Gy for Clinics A, B, C, and D, respectively). The mean dose to the bladder also decreased with the model-generated plans (5.4, 2.3, 3.0, and 4.1 Gy, respectively). The KBP model also identified that target coverage (D95%) improvements were possible for for Clinics A, B, and D (0.12, 1.65, and 2.75%) while target coverage decreased by 0.72% for Clinic C, demonstrating potentially different trade-offs made in clinical plans at different institutions. Conclusion: Quality control of dosimetric plan quality across a system of radiation oncology practices is possible with knowledge-based planning. By using a quality KBP model, smaller community-based clinics can potentially identify the areas of their treatment plans that may be improved, whether it be in normal-tissue sparing or improved target

    The objective of our research is to report on the diffusion of Clinical Governance, as introduced with the National Health Plan 2006-2008, by analysing the planning instruments set up by each Region (Regional Health Plans and Emergency Plans in regions with budget deficit), the organizational frameworks (Atti Aziendali, firm acts), and the surveys on performance and quality of healthcare among the Italian Local Health Units (Health Surveys). Our research was realized on September-December 2007 and consisted of the collection of all retrieved documents available on the web and on the online public access catalog (OPAC SBN) of the National Library Service. Futhermore, each document has been classified and analysed according to Chambers' Clinical Governance definition. A descriptive statistical and inferential analysis by applying the Chi-2 Test was performed to test the correlation between the diffusion of such a classified documents and the geographical partition of each LHU. Our results show a scarce diffusion of Firm acts (43%) and Health Surveys (24.9% of the total). Any remind to Clinical Governance instruments and methods inside each document resulted even poorer among both the organizational and performance surveys and the regional health planning frameworks, respectively.

  4. When does treatment plan optimization require inverse planning?

    Increasing maturity of image-based computer-aided design of three-dimensional conformal radiotherapy has recently sparked a great deal of work in the area of treatment plan optimization. Optimization of a conformal photon beam treatment plan is that exercise through which a set of intensity-modulated static beams or arcs is specified such that, when the plan is executed, 1) a region of homogeneous dose is produced in the patient with a shape which geometrically conforms (within a specified tolerance) to the three-dimensional shape of a designated target volume and 2) acceptably low incidental dose is delivered to non-target tissues. Interest in conformal radiotherapy arise from a fundamental assumption that there is significant value to be gained from aggressive customization of the treatment for each individual patient In our efforts to design optimal treatments, however, it is important to remember that, given the biological and economic realities of clinical radiotherapy, mathematical optimization of dose distribution metrics with respect to some minimal constraint set is not a necessary or even sufficient condition for design of a clinically optimal treatment. There is wide variation in the complexity of the clinical situations encountered in practice and there are a number of non-physical criteria to be considered in planning. There is also a complementary variety of computational and engineering means for achieving optimization. To date, the scientific dialogue regarding these techniques has concentrated on development of solutions to worst-case scenarios, largely in the absence of consideration of appropriate matching of solution complexity to problem complexity. It is the aim of this presentation to propose a provisional stratification of treatment planning problems, stratified by relative complexity, and to identify a corresponding stratification of necessary treatment planning techniques. It is asserted that the subset of clinical radiotherapy cases for

    Purpose: To report the first experience on the development of a cloud-based treatment planning system and investigate the performance improvement of dose calculation and treatment plan optimization of the cloud computing platform. Methods: A cloud computing-based radiation treatment planning system (cc-TPS) was developed for clinical treatment planning. Three de-identified clinical head and neck, lung, and prostate cases were used to evaluate the cloud computing platform. The de-identified clinical data were encrypted with 256-bit Advanced Encryption Standard (AES) algorithm. VMAT and IMRT plans were generated for the three de-identified clinical cases to determine the quality of the treatment plans and computational efficiency. All plans generated from the cc-TPS were compared to those obtained with the PC-based TPS (pc-TPS). The performance evaluation of the cc-TPS was quantified as the speedup factors for Monte Carlo (MC) dose calculations and large-scale plan optimizations, as well as the performance ratios (PRs) of the amount of performance improvement compared to the pc-TPS. Results: Speedup factors were improved up to 14.0-fold dependent on the clinical cases and plan types. The computation times for VMAT and IMRT plans with the cc-TPS were reduced by 91.1% and 89.4%, respectively, on average of the clinical cases compared to those with pc-TPS. The PRs were mostly better for VMAT plans (1.0 ≤ PRs ≤ 10.6 for the head and neck case, 1.2 ≤ PRs ≤ 13.3 for lung case, and 1.0 ≤ PRs ≤ 10.3 for prostate cancer cases) than for IMRT plans. The isodose curves of plans on both cc-TPS and pc-TPS were identical for each of the clinical cases. Conclusion: A cloud-based treatment planning has been setup and our results demonstrate the computation efficiency of treatment planning with the cc-TPS can be dramatically improved while maintaining the same plan quality to that obtained with the pc-TPS.

    We have co-registered MRI, CT and FBPA-PET images for BNCT in clinical practice. Co-registration improves the spatial accuracy of the treatment planning by enabling use of information from all the co-registered modalities. The multimodal co-registration has been implemented as a service product provided by the Imaging Center of Helsinki University Central Hospital to other departments. To increase the accuracy of co-registration and patient positioning in the head area BNCT, a patient-specific fixation mask suitable for PET, MRI and CT was developed. The goal of the fixation mask is to normalize the orientation of the patient's head and neck. Co-registration is performed at the image processing unit by using a rigid body model, mutual-information based algorithms and partly in-house developed software tools. The accuracy of co-registration is verified by comparing the locations of the external skin markers and anatomical landmarks in different modalities. After co-registration, the images are transformed and covered into a format required by the BNCT dose-planning software and set to the dose-planning unit of the hospital. So far co-registration has been done for 22 patients. The co-registration protocol has proved to be reliable and efficient. Some registration errors are seen on some patients in the neck area because the rigid-body model used in co-registration is not fully valid for the brain-neck entity. The registration accuracy in this area could likely be improved by implementing a co-registration procedure utilizing a partly non-rigid body model. (author)

    The transition to parenthood involves many stressors that can have implications for the couple relationship as well as the developmental environment of the child. Scholars and policymakers have recognized the potential for interventions that can help couples navigate these stressors to improve parenting and coparenting strategies. Such evidence-based programs are scarcely available, however, and little is known about the resources necessary to carry out these programs. This study examines the costs and resources necessary to implement Family Foundations, a program that addresses the multifaceted issues facing first-time parents through a series of pre- and post-natal classes. Costs were determined using a 6-step analytic process and are based on the first implementation of the program carried out through a five-year demonstration project. This assessment demonstrates how overall costs change across years as new cohorts of families are introduced, and how cost breakdowns differ by category as needs shift from training group leaders to sustaining program services. Information from this cost analysis helps clarify how the program could be made more efficient in subsequent implementations. We also consider how results may be used in future research examining economic benefits of participation in the program. PMID:24603052

    While women created the family planning (FP) movement, men have also been involved since its inception (albeit in a minor way). Today men must redefine masculinity in order to become more effective as FP providers and clients. While women have carved out newly self-sufficient identities, men have had to search for new identities which appropriately respond to changing gender relations. The Planned Parenthood of Central and Northern Arizona has 12 males on a staff of 130. The male FP providers have an opportunity to redefine gender relations, masculinity, and reproductive responsibility through their interactions with clients, whether the clients are themselves male or female. The male FP providers have a rare opportunity to exhibit a balance between the "fierceness of the warrior patient and the warmth of the parent" in their dealings with clients. Female clients of male FP providers can realize a therapeutic, emotionally-corrective experience. Male clients of male providers can receive insights into women's lives; into healthful living; and into ways to achieve greater access to feelings, emotions, and experiences. The changes at hand in the world demand that traditionally female values such as nurturing and compassion be brought into the traditionally male world of ambition, profit, and power. Male FP providers can contribute to this improvement as they affect one client at a time.

    The aim of this article is to provide an overview of existing studies on gay and lesbian parenthood and child development. Although 200,000 to 300,000 children could be concerned in 2010 in France, there is a lack of research on this issue in our country. Research among children raised by homosexual parents involves methodological issues, such as defining homosexual families, sampling cases and controls, and choosing structured or semi-structured evaluations. The fact that homosexual marriage, adoption and insemination are not presently legal in France could explain that only one study has been conducted in France in 2000 among 58 children raided by homosexual parents. This study concluded that these children did not show an increased rate of behavior or anxiety disorders. Concerns about lesbian parenting have focused on the absence of a father, the homosexual orientation of the mother, and their negative consequences on the development of the children. Research on parenting and child rearing has repeatedly compared lesbian and heterosexual families, and in the last 30 years a growing body of studies on lesbian parents and the development of their children has been published. Studies about child development, sexual orientation, gender identity, gender role behavior, emotional/behavioral development, social relationships and cognitive functioning showed no difference between children of lesbian mothers and those of heterosexual parents. Likewise, parental functioning, the mothers' psychological health and maternal skills were not significantly different among lesbian mothers than among heterosexual mothers. In studies concerning gay fathers, findings generally indicate no differences in sexual orientation, socialization, or psychological outcomes in children of gay fathers compared to children of heterosexual fathers. However, the first study on the adult attachment style dimensions of adult women who had gay or bisexual fathers suggested that they were

    Despite multiple calls for clinic-based services to identify and support women victimized by partner violence, screening remains uncommon in family planning clinics. Furthermore, traditional screening, based on disclosure of violence, may miss women who fear reporting their experiences. Strategies that are sensitive to the signs, symptoms and impact of trauma require exploration. In 2011, as part of a cluster randomized controlled trial, staff at 11 Pennsylvania family planning clinics were trained to offer a trauma-informed intervention addressing intimate partner violence and reproductive coercion to all women seeking care, regardless of exposure to violence. The intervention sought to educate women about available resources and harm reduction strategies. In 2013, at the conclusion of the trial, 18 providers, five administrators and 49 patients completed semistructured interviews exploring acceptability of the intervention and barriers to implementation. Consensus and open coding strategies were used to analyze the data. Providers reported that the intervention increased their confidence in discussing intimate partner violence and reproductive coercion. They noted that asking patients to share the educational information with other women facilitated the conversation. Barriers to implementation included lack of time and not having routine reminders to offer the intervention. Patients described how receiving the intervention gave them important information, made them feel supported and less isolated, and empowered them to help others. A universal intervention may be acceptable to providers and patients. However, successful implementation in family planning settings may require attention to system-level factors that providers view as barriers. Copyright © 2017 by the Guttmacher Institute.

    Purpose: In this study, the algorithms and calculation setting effect and contribution weighing on prostate Volumetric Modulated Arc Therapy (VMAT) based SBRT were evaluated for clinical analysis. Methods: A low risk prostate patient under SBRT was selected for the treatment planning evaluation. The treatment target was divided into low dose prescription target volume (PTV) and high Dose PTV. Normal tissue constraints include urethra and femur head, and rectum was separated into anterior, lateral and posterior parts. By varying the constraint limit of treatment plan calculation setting and algorithms, the effect on dose coverage and normal tissue dose constraint parameter carried effective comparison for the nominal prescription and constraint. For each setting, their percentage differences to the nominal value were calculated with geometric mean and harmonic mean. Results: In the arbitrary prostate SBRT case, 14 variables were selected for this evaluation by using nominal prescription and constraint. Six VMAT planning settings were anisotropic analytic algorithm stereotactic beam with and without couch structure in grid size of 1mm and 2mm, non stereotactic beam, Acuros algorithm . Their geometry means of the variable sets for these plans were 112.3%, 111.9%, 112.09%, 111.75%, 111.28%, and 112.05%. And the corresponding harmonic means were 2.02%, 2.16%, 3.15%, 4.74%, 5.47% and 5.55%. Conclusions: In this study, the algorithm difference shows relatively larger harmonic mean between prostate SBRT VMAT plans. This study provides a methodology to find sensitive combined variables related to clinical analysis, and similar approach could be applied to the whole treatment procedure from simulation to treatment in radiotherapy for big clinical data analysis

    We implemented the simplified Monte Carlo (SMC) method on graphics processing unit (GPU) architecture under the computer-unified device architecture platform developed by NVIDIA. The GPU-based SMC was clinically applied for four patients with head and neck, lung, or prostate cancer. The results were compared to those obtained by a traditional CPU-based SMC with respect to the computation time and discrepancy. In the CPU- and GPU-based SMC calculations, the estimated mean statistical errors of the calculated doses in the planning target volume region were within 0.5% rms. The dose distributions calculated by the GPU- and CPU-based SMCs were similar, within statistical errors. The GPU-based SMC showed 12.30–16.00 times faster performance than the CPU-based SMC. The computation time per beam arrangement using the GPU-based SMC for the clinical cases ranged 9–67 s. The results demonstrate the successful application of the GPU-based SMC to a clinical proton treatment planning. (note)

    In modern cancer management, treatment planning has progressed as a contemporary tool with all the advances in computing power in recent years. One of the advanced planning tools uses 3-dimensional (3D) data sets for accurate dose distributions in patient prescription. Among these planning processes, brachytherapy has been a very important part of a successful cancer management program, offering clinical benefits with specific or combined treatments with external beam therapy. In this chapter, we mainly discussed the Elekta Oncentra planning system, which is the main treatment planning tool for high-dose rate (HDR) modality in our facility and in many other facilities in the United States. HDR is a technically advanced form of brachytherapy; a high-intensity radiation source (3.6 mm in length) is delivered with step motor in submillimeter precision under computer guidance directly into the tumor areas while minimizing injury to surrounding normal healthy tissue. Oncentra planning is the key component to generate a deliverable brachytherapy procedure, which is executed on the microSelectron V3 remote afterloader treatment system. Creating a highly conformal plan can be a time-consuming task. The development of Oncentra software (version 4.5.3) offers a variety of useful tools that facilitate many of the clinical challenging tasks for planning, such as contouring and image reconstruction, as well as rapid planning calculations with dose and dose volume histogram analysis. Oncentra Brachy module creates workflow and optimizes the planning accuracy for wide varieties of clinical HDR treatments, such as skin, gynecologic (GYN), breast, prostate, and many other applications. The treatment file can also be transferred to the afterloader control station for speedy delivery. The design concept, calculation algorithms, and optimization modules presented some key characteristics to plan and treat the patients effectively and accurately. The dose distribution and accuracy of

    Treatment planning is a central part of radiation therapy, including delineation in tumor volumes and critical organs, setting treatment goals of prescription doses to the tumor targets and tolerance doses to the critical organs, and finally generation of treatment plans to meet the treatment goals. National groups like RTOG have led the effort to standardize treatment goals of the prescription doses to the tumor targets and tolerance doses to the critical organs based on accumulated knowledge from decades of abundant clinical trial experience. The challenge for each clinical department is how to achieve or surpass these set goals within the time constraints of clinical practice. Using fifteen testing cases from different treatment sites such as head and neck, prostate with and without pelvic lymph nodes, SBRT spine, we will present clinically utility of advanced planning tools, including knowledge based, automatic based, and multiple criteria based tools that are clinically implemented. The objectives of this session are: Understand differences among these three advanced planning tools Provide clinical assessments on the utility of the advanced planning tools Discuss clinical challenges of treatment planning with large variations in tumor volumes and their relationships with adjacent critical organs.

    Purpose: to report on the planning procedure, quality control, and clinical implementation of intensity-modulated arc therapy (IMAT) delivering a simultaneous integrated boost (SIB) in patients with primary irresectable cervix carcinoma. Patients and methods: six patients underwent PET-CT (positron emission tomography-computed tomography) and MRI (magnetic resonance imaging) before treatment planning. Prescription (25 fractions) was (1) a median dose (D{sub 50}) of 62, 58 and 56 Gy to the primary tumor (GTVcervix), primary clinical target volume (CTVcervix) and its planning target volume (PTVcervix), respectively; (2) a D{sub 50} of 60 Gy to the PET-positive lymph nodes (GTVnodes); (3) a minimal dose (D{sub 98}) of 45 Gy to the planning target volume of the elective lymph nodes (PTVnodes). IMAT plans were generated using an anatomy-based exclusion tool with the aid of weight and leaf position optimization. The dosimetric delivery of IMAT was validated preclinically using radiochromic film dosimetry. Results: five to nine arcs were needed to create valid IMAT plans. Dose constraints on D{sub 50} were not met in two patients (both GTVcervix: 1 Gy and 3 Gy less). D{sub 98} for PTVnodes was not met in three patients (1 Gy each). Film dosimetry showed excellent gamma evaluation. There were no treatment interruptions. Conclusion: IMAT allows delivering an SIB to the macroscopic tumor without compromising the dose to the elective lymph nodes or the organs at risk. The clinical implementation is feasible. (orig.)

    Catholic Church directives restrict family planning service provision at Catholic health care institutions. It is unclear whether obstetrics and gynecology clinics that are owned by or have business affiliations with Catholic hospitals offer family planning appointments. Mystery callers phoned 144 clinics nationwide that were found on Catholic hospital websites between December 2014 and February 2016, and requested appointments for birth control generally, copper IUD services specifically, tubal ligation and abortion. Chi-square and Fisher's exact tests assessed potential correlates of appointment availability, and multivariable logistic regressions were computed if bivariate testing suggested multiple correlates. Although 95% of clinics would schedule birth control appointments, smaller proportions would schedule appointments for copper IUDs (68%) or tubal ligation (58%); only 2% would schedule an abortion. Smaller proportions of Catholic-owned than of Catholic-affiliated clinics would schedule appointments for birth control (84% vs. 100%), copper IUDs (4% vs. 97%) and tubal ligation (29% vs. 72%); for birth control and copper IUD services, no other clinic characteristics were related to appointment availability. Multivariable analysis confirmed that tubal ligation appointments were less likely to be offered at Catholic-owned than at Catholic-affiliated clinics (odds ratio. 0.1); location and association with one of the top 10 Catholic health care systems also were significant. Adherence to church directives is inconsistent at Catholic-associated clinics. Women visiting such clinics who want highly effective methods may need to rely on less effective methods or delay method uptake while seeking services elsewhere.

    Radiotherapy for cervix cancer is challenging in patients exhibiting large daily changes in the pelvic anatomy, therefore adaptive treatments (ART) have been proposed. The aim of this study was the clinical implementation and subsequent evaluation of plan-of-the-day (POTD)-ART for cervix cancer in supine positioning. The described workflow was based on standard commercial equipment and current quality assurance (QA) methods. A POTD strategy, which employs a VMAT plan library consisting of an empty bladder plan, a full bladder plan and a motion robust backup plan, was developed. Daily adaption was guided by cone beam computed tomography (CBCT) imaging after which the best plan from the library was selected. Sixteen patients were recruited in a clinical study on ART, for nine POTD was applied due to their large organ motion derived from two computed tomography (CT) scans with variable bladder filling. All patients were treated to 45Gy in 25 fractions. Plan selection frequencies over the treatment course were analyzed. Daily doses in the rectum, bladder and cervix-uterus target (CTV-T) were derived and compared to a simulated non-adapted treatment (non-ART), which employed the robust plan for each fraction. Additionally, the adaption consistency was determined by repeating the plan selection procedure one month after treatment by a group of experts. ART-specific QA methods are presented. 225 ART fractions with CBCTs were analyzed. The empty bladder plan was delivered in 49% of the fractions in the first treatment week and this number increased to 78% in the fifth week. The daily coverage of the CTV-T was equivalent between ART and the non-ART simulation, while the daily total irradiated volume V42.75Gy (95% of prescription dose) was reduced by a median of 87cm 3 . The median delivered V42.75Gy was 1782cm 3 . Daily delivered doses (V42.75Gy, V40Gy, V30G) to the organs at risk were statistically significantly reduced by ART, with a median difference in daily V42.75Gy in

    More and more lesbian couples are planning parenthood through donor insemination and IVF and the number of planned lesbian families is growing in Sweden and other western countries. Research has shown that lesbian couples report as much overall satisfaction in their relationships as do heterosexual couples. However, although parenthood is highly desired, many parents are unaware of the demands of parenthood and the strain on their relationship that the arrival of the baby might bring. The aim of this study was to compare lesbian and heterosexual couples' perceptions of relationship satisfaction at a three-year follow up after assisted reproduction. The present study is a part of the Swedish study on gamete donation, a prospective longitudinal cohort study. The present study constitutes a three-year follow up assessment of lesbian and heterosexual couples after assisted reproduction. Participants requesting assisted reproduction at all fertility clinics performing gamete donation in Sweden, were recruited consecutively during 2005-2008. A total of 114 lesbian women (57 treated women and 57 partners) and 126 heterosexual women and men (63 women and 63 men) participated. Participants responded to the ENRICH inventory at two time points during 2005-2011; at the commencement of treatment (time point 1) and about three years after treatment termination (time point 3). To evaluate the bivariate relationships between the groups (heterosexual and lesbian) and socio-demographic factors Pearson's Chi- square test was used. Kolmogorov-Smirnov test was used for testing of normality, Mann-Whitney U- test to examine differences in ENRICH between the groups and paired samples t-test to examine scores over time. Lesbian couples reported higher relationship satisfaction than heterosexual couples, however the heterosexual couples satisfaction with relationship quality was not low. Both lesbian and heterosexual couples would be classified accordingly to ENRICH-typology as vitalized or

    The main aim of the current study was to assess the dosimetric accuracy and clinical quality of volumetric modulated arc therapy (VMAT) plans for stereotactic (stage I) and conventional (stage III) lung cancer treatments planned with Eclipse version 10.0 Anisotropic Analytical Algorithm (AAA) and Acuros XB (AXB) algorithm. The dosimetric impact of using AAA instead of AXB, and grid size 2.5 mm instead of 1.0 mm for VMAT treatment plans was evaluated. The clinical plan quality of AXB VMAT was assessed using 45 stage I and 73 stage III patients, and was compared with published results, planned with VMAT and hybrid-VMAT techniques. The dosimetric impact on near-minimum PTV dose (D 98% ) using AAA instead of AXB was large (underdose up to 12.3%) for stage I and very small (underdose up to 0.8%) for stage III lung treatments. There were no significant differences for dose volume histogram (DVH) values between grid sizes. The calculation time was significantly higher for AXB grid size 1.0 than 2.5 mm (p < 0.01). The clinical quality of the VMAT plans was at least comparable with clinical qualities given in literature of lung treatment plans with VMAT and hybrid-VMAT techniques. The average mean lung dose (MLD), lung V 20Gy and V 5Gy in this study were respectively 3.6 Gy, 4.1% and 15.7% for 45 stage I patients and 12.4 Gy, 19.3% and 46.6% for 73 stage III lung patients. The average contra-lateral lung dose V 5Gy-cont was 35.6% for stage III patients. For stereotactic and conventional lung treatments, VMAT calculated with AXB grid size 2.5 mm resulted in accurate dose calculations. No hybrid technique was needed to obtain the dose constraints. AXB is recommended instead of AAA for avoiding serious overestimation of the minimum target doses compared to the actual delivered dose

    To understand requests for nursing Clinical Decision Support (CDS) interventions at a large integrated health system undergoing vendor-based EHR implementation. In addition, to establish a process to guide both short-term implementation and long-term strategic goals to meet nursing CDS needs. We conducted an environmental scan to understand current state of nursing CDS over three months. The environmental scan consisted of a literature review and an analysis of CDS requests received from across our health system. We identified existing high priority CDS and paper-based tools used in nursing practice at our health system that guide decision-making. A total of 46 nursing CDS requests were received. Fifty-six percent (n=26) were specific to a clinical specialty; 22 percent (n=10) were focused on facilitating clinical consults in the inpatient setting. "Risk Assessments/Risk Reduction/Promotion of Healthy Habits" (n=23) was the most requested High Priority Category received for nursing CDS. A continuum of types of nursing CDS needs emerged using the Data-Information-Knowledge-Wisdom Conceptual Framework: 1) facilitating data capture, 2) meeting information needs, 3) guiding knowledge-based decision making, and 4) exposing analytics for wisdom-based clinical interpretation by the nurse. Identifying and prioritizing paper-based tools that can be modified into electronic CDS is a challenge. CDS strategy is an evolving process that relies on close collaboration and engagement with clinical sites for short-term implementation and should be incorporated into a long-term strategic plan that can be optimized and achieved overtime. The Data-Information-Knowledge-Wisdom Conceptual Framework in conjunction with the High Priority Categories established may be a useful tool to guide a strategic approach for meeting short-term nursing CDS needs and aligning with the organizational strategic plan.

    This study draws from a life-course perspective in examining trajectories of mothers’ depressive symptoms across their adolescent daughters’ adjustment to parenthood in 204 Mexican-origin families using latent class growth analysis. Four distinct trajectories were identified based on mothers’ depressive symptoms prior to the birth and 10 and 24 months postpartum. Two trajectories were characterized by stable levels of depressive symptoms but were differentiated in their levels of symptoms (i.e., High/Stable and Low/Stable). The remaining two trajectories were characterized by changes from pre- to post-birth, with one group exhibiting increases in depressive symptoms (i.e., Low/Post-Birth Increase) and the other group characterized by decreases in depressive symptoms (i.e., Low/Post-Birth Decrease). Consistent with a risk and resilience perspective, mothers with more disadvantaged socioeconomic circumstances and fewer intrapersonal resources (i.e., self-esteem, ethnic identity affirmation) were more likely to be members of the High/Stable group. In addition, daughters of mothers in the High/Stable group were more likely to have lower self-esteem as compared to daughters in the other three groups. Collectively, these findings suggested that the High/Stable group was at risk for adjustment difficulties from the third trimester to two years postpartum. In contrast, membership in the Low/Post-Birth Decrease trajectory group was associated with lower depressive symptoms and higher self-esteem for mothers and daughters. Findings point to the need to identify mothers who are at risk for depressive symptoms during their adolescent daughters’ pregnancy and offer prevention and intervention programs that reduce risks and enhance protective factors.

    Background and purpose: This study is to determine if the overlap-volume histogram (OVH)-driven planning methodology can be adapted to robotic SBRT (CyberKnife Robotic Radiosurgery System) to further minimize the bladder and rectal doses achieved in plans manually-created by clinical planners. Methods and materials: A database containing clinically-delivered, robotic SBRT plans (7.25 Gy/fraction in 36.25 Gy) of 425 patients with localized prostate cancer was used as a cohort to establish an organ’s distance-to-dose model. The OVH-driven planning methodology was refined by adding the PTV volume factor to counter the target’s dose fall-off effect and incorporated into Multiplan to automate SBRT planning. For validation, automated plans (APs) for 12 new patients were generated, and their achieved dose/volume values were compared to the corresponding manually-created, clinically-delivered plans (CPs). A two-sided, Wilcoxon rank-sum test was used for statistical comparison with a significance level of p < 0.05. Results: PTV’s V(36.25 Gy) was comparable: 95.6% in CPs comparing to 95.1% in APs (p = 0.2). On average, the refined approach lowered V(18.12 Gy) to the bladder and rectum by 8.2% (p < 0.05) and 6.4% (p = 0.14). A physician confirmed APs were clinically acceptable. Conclusions: The improvements in APs could further reduce toxicities observed in SBRT for organ-confined prostate cancer

    Full Text Available Objective: Intimate partner violence (IPV is a large public health problem with far-reaching consequences for those involved. The aim of this study was to explore fathers’ experiences of change during pregnancy and early parenthood in the context of IPV. Methods: The methodological approach in this interview study was hermeneutics, based on a lifeworld perspective. Ten men, who had subjected their partners to violence during the childbearing period, and had become fathers within the previous 6 years, participated. Results: The analysis revealed four themes: beginning to acknowledge that you are inflicting violence, receiving confirmation that you are more than just a perpetrator of violence, becoming aware of the child, and the desire to receive support in the process of learning how to become a father. Levinas’ concept “the face of the other” is used to interpret the findings. Conclusion: This study contributes to a more nuanced and expanded picture of IPV. It shows that men who inflict violence want to be and learn how to be fathers. We need more knowledge about how to stop violent acts and support these men in the process of fatherhood.

    In 1957, the Indonesian Planned Parenthood Federation was established. In 1970, the National Family Planning Board (BKKBN) was created. The current contraceptive prevalence rate is 45-50%. The family planning program began with a health-oriented approach. To promote acceptance, religious leaders were asked to provide legitimacy to the program. Through their efforts, it became possible to include all the means and medication used for family planning services within the program. In developing an IEC strategy to encourage couples to accept family planning, 3 main factors were studied: 1) the types of innovations that were to be introduced, 2) the characteristics of the Indonesian community, and 3) the need for an IEC strategy to convey the programs messages the community and make the community itself the agent of the innovation being introduced. The elements of the strategy were introduced stage by stage to avoid unnecessary debate. Another strategic step was the introduction of family planning using a community approach. A 3rd strategic step was a shift from couples as family planning acceptors to the introduction of the norm of a small, happy, and prosperous family. The 1st stage, expansion of program coverage, 1) promoted the need for and desirability of family planning to make the small and happy family the norm and 2) supplied contraceptives and information about contraceptives throughout Indonesia. The 2nd stage, the program maintenance approach, included 1) an increase in the frequency of visits to villages by mobile family planning teams, 2) the integration of family planning activities with other health-related activities, and 3) giving people a wider choice of methods and helping them to choose the most suitable method for them. The 3rd stage made family planning a community activity, integrated within the economic and social fabric of community life. The general strategy of the IEC program is to make the various target groups full family planning

    The purpose of this study was to describe the development of a clinical model for lung cancer patients treated with stereotactic body radiotherapy (SBRT) within a knowledge-based algorithm for treatment planning, and to evaluate the model performance and applicability to different planning techniques, tumor locations, and beam arrangements. 105 SBRT plans for lung cancer patients previously treated at our institution were included in the development of the knowledge-based model (KBM). The KBM was trained with a combination of IMRT, VMAT, and 3D CRT techniques. Model performance was validated with 25 cases, for both IMRT and VMAT. The full KBM encompassed lesions located centrally vs. peripherally (43:62), upper vs. lower (62:43), and anterior vs. posterior (60:45). Four separate sub-KBMs were created based on tumor location. Results were compared with the full KBM to evaluate its robustness. Beam templates were used in conjunction with the optimizer to evaluate the model's ability to handle suboptimal beam placements. Dose differences to organs-at-risk (OAR) were evaluated between the plans gener-ated by each KBM. Knowledge-based plans (KBPs) were comparable to clinical plans with respect to target conformity and OAR doses. The KBPs resulted in a lower maximum spinal cord dose by 1.0 ± 1.6 Gy compared to clinical plans, p = 0.007. Sub-KBMs split according to tumor location did not produce significantly better DVH estimates compared to the full KBM. For central lesions, compared to the full KBM, the peripheral sub-KBM resulted in lower dose to 0.035 cc and 5 cc of the esophagus, both by 0.4Gy ± 0.8Gy, p = 0.025. For all lesions, compared to the full KBM, the posterior sub-KBM resulted in higher dose to 0.035 cc, 0.35 cc, and 1.2 cc of the spinal cord by 0.2 ± 0.4Gy, p = 0.01. Plans using template beam arrangements met target and OAR criteria, with an increase noted in maximum heart dose (1.2 ± 2.2Gy, p = 0.01) and GI (0.2 ± 0.4, p = 0.01) for the nine

    The transition to parenthood involves many stressors that can have implications for the couple relationship as well as the developmental environment of the child. Scholars and policymakers have recognized the potential for interventions that can help couples navigate these stressors to improve parenting and coparenting strategies. Such evidence-based programs are scarcely available, however, and little is known about the resources necessary to carry out these programs. This study examines the costs and resources necessary to implement Family Foundations, a program that addresses the multifaceted issues facing first-time parents through a series of pre- and post-natal classes. Costs were determined using a 6-step analytic process and are based on the first implementation of the program carried out through a five-year demonstration project. This assessment demonstrates how overall costs change across years as new cohorts of families are introduced, and how cost breakdowns differ by category as needs shift from training group leaders to sustaining program services. Information from this cost analysis helps clarify how the program could be made more efficient in subsequent implementations. We also consider how results may be used in future research examining economic benefits of participation in the program. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Background and purpose: The purpose of this work was a comparison of realistic IMRT plans based on the same CT-image data set and a common predefined set of dose objectives for the planning target volume and the organs at risk. This work was part of the larger European QUASIMODO IMRT verification project. Materials and methods: Eleven IMRT plans were produced by nine different European groups, each applying a representative set of clinically used IMRT treatment planning systems. The plans produced were to be deliverable in a clinically acceptable treatment time with the local technical equipment. All plans were characterized using a set of different quality measures such as dose-volume histograms, number of monitor units and treatment time. Results: Only one plan was able to fulfil all dose objectives strictly; six plans failed some of the objectives but were still considered to be clinically acceptable; four plans were not able to reach the objectives. Additional quality scores such as the number of monitor units and treatment time showed large variations, which mainly depend on the delivery technique. Conclusion: The presented planning study showed that with nearly all presently available IMRT planning and delivery systems comparable dose distributions could be achieved if the planning goals are clearly defined in advance

    The radiotherapy treatment planning process has evolved over the years with innovations in treatment planning, treatment delivery and imaging systems. Treatment modality and simulation technologies are also rapidly improving and affecting the planning process. For example, Image-guided-radiation-therapy has been widely adopted for patient setup, leading to margin reduction and isocenter repositioning after simulation. Stereotactic Body radiation therapy (SBRT) and Radiosurgery (SRS) have gradually become the standard of care for many treatment sites, which demand a higher throughput for the treatment plans even if the number of treatments per day remains the same. Finally, simulation, planning and treatment are traditionally sequential events. However, with emerging adaptive radiotherapy, they are becoming more tightly intertwined, leading to iterative processes. Enhanced efficiency of planning is therefore becoming more critical and poses serious challenge to the treatment planning process; Lean Six Sigma approaches are being utilized increasingly to balance the competing needs for speed and quality. In this symposium we will discuss the treatment planning process and illustrate effective techniques for managing workflow. Topics will include: Planning techniques: (a) beam placement, (b) dose optimization, (c) plan evaluation (d) export to RVS. Planning workflow: (a) import images, (b) Image fusion, (c) contouring, (d) plan approval (e) plan check (f) chart check, (g) sequential and iterative process Influence of upstream and downstream operations: (a) simulation, (b) immobilization, (c) motion management, (d) QA, (e) IGRT, (f) Treatment delivery, (g) SBRT/SRS (h) adaptive planning Reduction of delay between planning steps with Lean systems due to (a) communication, (b) limited resource, (b) contour, (c) plan approval, (d) treatment.

    The radiotherapy treatment planning process has evolved over the years with innovations in treatment planning, treatment delivery and imaging systems. Treatment modality and simulation technologies are also rapidly improving and affecting the planning process. For example, Image-guided-radiation-therapy has been widely adopted for patient setup, leading to margin reduction and isocenter repositioning after simulation. Stereotactic Body radiation therapy (SBRT) and Radiosurgery (SRS) have gradually become the standard of care for many treatment sites, which demand a higher throughput for the treatment plans even if the number of treatments per day remains the same. Finally, simulation, planning and treatment are traditionally sequential events. However, with emerging adaptive radiotherapy, they are becoming more tightly intertwined, leading to iterative processes. Enhanced efficiency of planning is therefore becoming more critical and poses serious challenge to the treatment planning process; Lean Six Sigma approaches are being utilized increasingly to balance the competing needs for speed and quality. In this symposium we will discuss the treatment planning process and illustrate effective techniques for managing workflow. Topics will include: Planning techniques: (a) beam placement, (b) dose optimization, (c) plan evaluation (d) export to RVS. Planning workflow: (a) import images, (b) Image fusion, (c) contouring, (d) plan approval (e) plan check (f) chart check, (g) sequential and iterative process Influence of upstream and downstream operations: (a) simulation, (b) immobilization, (c) motion management, (d) QA, (e) IGRT, (f) Treatment delivery, (g) SBRT/SRS (h) adaptive planning Reduction of delay between planning steps with Lean systems due to (a) communication, (b) limited resource, (b) contour, (c) plan approval, (d) treatment. Optimizing planning processes: (a) contour validation (b) consistent planning protocol, (c) protocol/template sharing, (d) semi

    Numerous cross-sectional studies investigated the link between marital status and BMI in the context of competing social science theories (marriage market, marriage selection, marriage protection and social obligation), frequently offering conflicting theoretical predictions and conflicting empirical findings. This study analysed the effects of marriage, divorce, pregnancy, and parenthood on male BMI in a longitudinal setting, avoiding the estimation bias of cross-sectional studies and allowing for an analysis of BMI fluctuation over time and the dynamic effects of these events. Using the Panel Study of Income Dynamics 1999-2013 dataset (N = 8729), this study was the first to employ a dynamic panel-data estimation to examine the static and dynamic effects of marriage, divorce, and fatherhood on male BMI. The study showed that married men have higher BMI, but marital status changes largely drove this static effect, namely, an increase in BMI in the period following marriage, and a decrease in BMI preceding and following divorce. Thus, this study found marked evidence in support of the marriage market and social obligation theories' predictions about male BMI, and supports neither marriage protection theory nor marriage selection theory. Wives' pregnancies had no significant effect on BMI; instead, men tend to have higher BMI in the periods following childbirth. Finally, analyses showed marked contemporaneous correlations between husband and wife BMI over the course of marriage. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The Plan-Do-Study-Act (PDSA) cycle is a commonly used improvement process in health care settings, although its documented use in pragmatic clinical research is rare. A recent pragmatic clinical research study, called the Strategies and Opportunities to STOP Colon Cancer in Priority Populations (STOP CRC), used this process to optimize the research implementation of an automated colon cancer screening outreach program in intervention clinics. We describe the process of using this PDSA approach, the selection of PDSA topics by clinic leaders, and project leaders' reactions to using PDSA in pragmatic research. STOP CRC is a cluster-randomized pragmatic study that aims to test the effectiveness of a direct-mail fecal immunochemical testing (FIT) program involving eight Federally Qualified Health Centers in Oregon and California. We and a practice improvement specialist trained in the PDSA process delivered structured presentations to leaders of these centers; the presentations addressed how to apply the PDSA process to improve implementation of a mailed outreach program offering colorectal cancer screening through FIT tests. Center leaders submitted PDSA plans and delivered reports via webinar at quarterly meetings of the project's advisory board. Project staff conducted one-on-one, 45-min interviews with project leads from each health center to assess the reaction to and value of the PDSA process in supporting the implementation of STOP CRC. Clinic-selected PDSA activities included refining the intervention staffing model, improving outreach materials, and changing workflow steps. Common benefits of using PDSA cycles in pragmatic research were that it provided a structure for staff to focus on improving the program and it allowed staff to test the change they wanted to see. A commonly reported challenge was measuring the success of the PDSA process with the available electronic medical record tools. Understanding how the PDSA process can be applied to pragmatic

    Radio-frequency ablation (RFA) is a promising minimal-invasive treatment option for early liver cancer, however monitoring or predicting the size of the resulting tissue necrosis during the RFA-procedure is a challenging task, potentially resulting in a significant rate of under- or over treatments. Currently there is no reliable lesion size prediction method commercially available. ClinicIMPPACT is designed as multicenter-, prospective-, non-randomized clinical trial to evaluate the accuracy and efficiency of innovative planning and simulation software. 60 patients with early liver cancer will be included at four European clinical institutions and treated with the same RFA system. The preinterventional imaging datasets will be used for computational planning of the RFA treatment. All ablations will be simulated simultaneously to the actual RFA procedure, using the software environment developed in this project. The primary outcome measure is the comparison of the simulated ablation zones with the true lesions shown in follow-up imaging after one month, to assess accuracy of the lesion prediction. This unique multicenter clinical trial aims at the clinical integration of a dedicated software solution to accurately predict lesion size and shape after radiofrequency ablation of liver tumors. Accelerated and optimized workflow integration, and real-time intraoperative image processing, as well as inclusion of patient specific information, e.g. organ perfusion and registration of the real RFA needle position might make the introduced software a powerful tool for interventional radiologists to optimize patient outcomes.

    Achieving the Millennium Development Goals (MDGs) and combating hotspots with escalating but preventable communicable diseases remain major challenges in Africa. The European and Developing Countries Clinical Trials Partnership (EDCTP) intervened to combat poverty-related diseases including malaria, tuberculosis and HIV/AIDS, and to conduct multi-centre clinical trials and multi-disciplinary health research through an innovative model of regional Networks of Excellence (NoEs). We participated in a quasi-formative evaluation between October and December 2011 on the 4 regional-led research networks. These included the: Central Africa Network on Tuberculosis, HIV/AIDS and Malaria (CANTAM); East African Consortium for Clinical Research (EACCR); West African Network of Excellence for TB, AIDS and Malaria (WANETAM), and the Trials of Excellence for Southern Africa (TESA) launched between 2009 and 2010. We shared a participatory appraisal of field reports, progress reports and presentations from each network to jointly outline the initial experiences of the merits, outputs and lessons learnt. The self-regulating democratic networks, with 64 institutions in 21 African countries, have trained over 1, 000 African scientists, upgraded 36 sites for clinical trials, leveraged additional € 24 million and generated 38 peer-reviewed publications through networking and partnerships. The shared initial merits and lessons learnt portray in part the strengthened capacity of these networks for improved research coordination and conduct of planned multi-center clinical trials in Africa. Increased funding by African agencies, governments and international health partners will ensure sustainability of these networks for research capacity development and demonstrate their commitment to achieving the MDGs in Africa.

    The Monte Carlo (MC) method has been shown through many research studies to calculate accurate dose distributions for clinical radiotherapy, particularly in heterogeneous patient tissues where the effects of electron transport cannot be accurately handled with conventional, deterministic dose algorithms. Despite its proven accuracy and the potential for improved dose distributions to influence treatment outcomes, the long calculation times previously associated with MC simulation rendered this method impractical for routine clinical treatment planning. However, the development of faster codes optimized for radiotherapy calculations and improvements in computer processor technology have substantially reduced calculation times to, in some instances, within minutes on a single processor. These advances have motivated several major treatment planning system vendors to embark upon the path of MC techniques. Several commercial vendors have already released or are currently in the process of releasing MC algorithms for photon and/or electron beam treatment planning. Consequently, the accessibility and use of MC treatment planning algorithms may well become widespread in the radiotherapy community. With MC simulation, dose is computed stochastically using first principles; this method is therefore quite different from conventional dose algorithms. Issues such as statistical uncertainties, the use of variance reduction techniques, the ability to account for geometric details in the accelerator treatment head simulation, and other features, are all unique components of a MC treatment planning algorithm. Successful implementation by the clinical physicist of such a system will require an understanding of the basic principles of MC techniques. The purpose of this report, while providing education and review on the use of MC simulation in radiotherapy planning, is to set out, for both users and developers, the salient issues associated with clinical implementation and

    Self-administration of subcutaneous depot medroxyprogesterone acetate (DMPA-sc) is feasible, acceptable, and effective. Our objective was to compare one-year continuation of DMPA-sc between women randomized to self-administration versus clinic administration. We randomized 401 females ages 15-44 requesting DMPA at clinics in Texas and New Jersey to self-administration or clinic administration in a 1:1 allocation. Clinic staff taught participants randomized to self-administration to self-inject and observed the first injection; participants received instructions, a sharps container, and three doses for home use. Participants randomized to clinic administration received usual care. All participants received DMPA-sc at no cost and injection reminders via text message or email. We conducted follow-up surveys at six and 12 months. Three hundred thirty-six participants (84%) completed the 12-month survey; 316 completed both follow-up surveys (an 80% response rate excluding eight withdrawals). Participants ranged in age from 16-44. One-year DMPA continuous use was 69% in the self-administration group and 54% in the clinic group (p=.005). There were three self-reported pregnancies during the study period, all occurred in the clinic group; all three women had discontinued DMPA and one reported her pregnancy as intended. Among the self-administration group, 97% reported that self-administration was very or somewhat easy; 87% would recommend self-administration of DMPA-sc to a friend. Among the clinic group, 52% reported interest in self-administration in the future. Satisfaction was similar between groups. No serious adverse events were reported. DMPA self-administration improves contraceptive continuation and is a feasible and acceptable option for women and adolescents. Self-administration of subcutaneous DMPA can improve contraceptive access, autonomy, and continuation, and is a feasible and acceptable option for women and adolescents. It should be made widely available

    Treatment planning is a central part of radiation therapy, including delineation in tumor volumes and critical organs, setting treatment goals of prescription doses to the tumor targets and tolerance doses to the critical organs, and finally generation of treatment plans to meet the treatment goals. National groups like RTOG have led the effort to standardize treatment goals of the prescription doses to the tumor targets and tolerance doses to the critical organs based on accumulated knowledge from decades of abundant clinical trial experience. The challenge for each clinical department is how to achieve or surpass these set goals within the time constraints of clinical practice. Using fifteen testing cases from different treatment sites such as head and neck, prostate with and without pelvic lymph nodes, SBRT spine, we will present clinically utility of advanced planning tools, including knowledge based, automatic based, and multiple criteria based tools that are clinically implemented. The objectives of this session are: Understand differences among these three advanced planning tools Provide clinical assessments on the utility of the advanced planning tools Discuss clinical challenges of treatment planning with large variations in tumor volumes and their relationships with adjacent critical organs.

    64 women clients of Planned Parenthood of Evansville (Indiana) used Enovid (5 mg norethynodrel and .075 mg mestranol, combined) for 2 1/2 to 6 years. A "25-Month Club" card and free pills were given to encourage continuation in the study, and 33 women (52%) remained until study termination. The group ranged in age from 18-40 years, mean 27 years, and in parity 0 to 12, mean 4. No pregnancies, cancer of reproductive organs or thromboembolism occurred. Side effects, recorded by interview according to a standard form, included: cervicitis 48%, vaginal discharge 42%; dysmenorrhea 61% pretreatment, 42% improved, 11% new symptoms; breast complaints 33%; 2-15 lb weight gain 19%. 12% reported no side effects, although the author commented that the 25-Month Club policy might have discouraged reporting of side effects.

    The goal of this study was to exam the efficacy of current DVH based clinical guidelines draw from photon experience for lung cancer radiation therapy on proton therapy. Comparison proton plans and IMRT plans were generated for 10 lung patients treated in our proton facility. A gEUD based plan evaluation method was developed for plan evaluation. This evaluation method used normal lung gEUD(a) curve in which the model parameter "a" was sampled from the literature reported value. For all patients, the proton plans delivered lower normal lung V 5 Gy with similar V 20 Gy and similar target coverage. Based on current clinical guidelines, proton plans were ranked superior to IMRT plans for all 10 patients. However, the proton and IMRT normal lung gEUD(a) curves crossed for 8 patients within the tested range of "a", which means there was a possibility that proton plan would be worse than IMRT plan for lung sparing. A concept of deficiency index (DI) was introduced to quantify the probability of proton plans doing worse than IMRT plans. By applying threshold on DI, four patients' proton plan was ranked inferior to the IMRT plan. Meanwhile if a threshold to the location of curve crossing was applied, 6 patients' proton plan was ranked inferior to the IMRT plan. The contradictory ranking results between the current clinical guidelines and the gEUD(a) curve analysis demonstrated there is potential pitfalls by applying photon experience directly to the proton world. A comprehensive plan evaluation based on radio-biological models should be carried out to decide if a lung patient would really be benefit from proton therapy. © 2018 The Authors.

    Purpose: We propose a workflow to improve access to stereotactic ablative radiation therapy (SABR) for rural patients. When implemented, a separate trip to the central facility for simulation can be eliminated. Two elements are required: (1) Fabrication of custom immobilization devices to match positioning on prior diagnostic CT (dxCT). (2) Remote radiation pre-planning on dxCT, with transfer of contours/plan to simulation CT (simCT) and initiation of treatment same-day or next day. In this retrospective study, we validated part 2 of the workflow using patients already treated with SABR for upper lobe lung tumors. Methods: Target/normal structures were contoured on dxCT; a plan was created and approved by the physician. Structures were transferred to simCT using deformable image registration and the plan was re-optimized on simCT. Plan quality was evaluated through comparison to gold-standard structures contoured on simCT and a gold-standard plan based on these structures. Workflow-generated plan quality in this study represents a worst-case scenario as these patients were not treated using custom immobilization to match dxCT position as would be done when the workflow is implemented clinically. Results: 5/6 plans created through the pre-planning workflow were clinically acceptable. For all six plans, the gold-standard GTV received full prescription dose, along with median PTV V95%=95.2% and median PTV D95%=95.4%. Median GTV DSC=0.80, indicating high degree of similarity between the deformed and gold-standard GTV contours despite small GTV sizes (mean=3.0cc). One outlier (DSC=0.49) resulted in inadequate PTV coverage (V95%=62.9%) in the workflow plan; in clinical practice, this mismatch between deformed/gold-standard GTV would be revised by the physician after deformable registration. For all patients, normal tissue doses were comparable to the gold-standard plan and well within constraints. Conclusion: Pre-planning SABR cases on diagnostic imaging generated

    Purpose: To evaluate whether Auto-Planning based volumetric-modulated radiotherapy (auto-VMAT) can reduce manual interaction time during treatment planning and improve plan quality for rectal cancer radiotherapy. Methods: Ten rectal cancer patients (stage II and III) after radical resection using Dixon surgery were enrolled. All patients were treated with VMAT technique. The manual VMAT plans (man-VMAT) were designed in the Pinnacle treatment planning system (Version 9.10) following the standard treatment planning procedure developed in our department. Clinical plans were manually designed by our experienced dosimetrists. Additionally, an auto-VMAT plan was created for each patient using Auto-Planning module. However, manual interaction was still applied to meet the clinical requirements. The treatment planning time and plan quality surrogated by the DVH parameters were compared between manual and automated plans. Results: The total planning time and manual interaction time were 50.38 and 4.47 min for the auto-VMAT and 36.81 and 16.94 min for the man-VMAT (t=60.14,−23.86; p=0.000, 0.000). In terms of plan quality, both plans meet the clinical requirements. The PTV homogeneity index (HI) and conformity index (CI) were 0.054 and 0.822 for the auto-VMAT and 0.059 and 0.815 for the man-VMAT (t=−1.72, 0.36;p=0.119,0.730).Compared to the man-VMAT, the auto-VMAT showed reduction of 11.9% and 0.7% in V40 and V50 of the bladder, respectively.The V30 and D mean were reduced by 14.0% and 5.1Gy in the left femur and 12.2% and 3.8Gy in the right femur. Conclusion: The Auto-Planning based VMAT plans not only shows similar or superior plan quality to the manual ones in the rectal cancer radiotherapy, but also improve the planning efficiency significantly. However, manual interactions are still required to achieve a clinically acceptable plan based on our experiences.

    Purpose: Planning studies to compare x-ray and proton techniques and to select the most suitable technique for each patient have been hampered by the nonequivalence of several aspects of treatment planning and delivery. A fair comparison should compare similarly advanced delivery techniques from current clinical practice and also assess the robustness of each technique. The present study therefore compared volumetric modulated arc therapy (VMAT) and single-field optimization (SFO) spot scanning proton therapy plans created using a simultaneous integrated boost (SIB) for dose escalation in midesophageal cancer and analyzed the effect of setup and range uncertainties on these plans. Methods and Materials: For 21 patients, SIB plans with a physical dose prescription of 2 Gy or 2.5 Gy/fraction in 25 fractions to planning target volume (PTV)_5_0_G_y or PTV_6_2_._5_G_y (primary tumor with 0.5 cm margins) were created and evaluated for robustness to random setup errors and proton range errors. Dose–volume metrics were compared for the optimal and uncertainty plans, with P<.05 (Wilcoxon) considered significant. Results: SFO reduced the mean lung dose by 51.4% (range 35.1%-76.1%) and the mean heart dose by 40.9% (range 15.0%-57.4%) compared with VMAT. Proton plan robustness to a 3.5% range error was acceptable. For all patients, the clinical target volume D_9_8 was 95.0% to 100.4% of the prescribed dose and gross tumor volume (GTV) D_9_8 was 98.8% to 101%. Setup error robustness was patient anatomy dependent, and the potential minimum dose per fraction was always lower with SFO than with VMAT. The clinical target volume D_9_8 was lower by 0.6% to 7.8% of the prescribed dose, and the GTV D_9_8 was lower by 0.3% to 2.2% of the prescribed GTV dose. Conclusions: The SFO plans achieved significant sparing of normal tissue compared with the VMAT plans for midesophageal cancer. The target dose coverage in the SIB proton plans was less robust to random setup errors and might be

The clinical target volume D{sub 98} was lower by 0.6% to 7.8% of the prescribed dose, and the GTV D{sub 98} was lower by 0.3% to 2.2% of the prescribed GTV dose. Conclusions: The SFO plans achieved significant sparing of normal tissue compared with the VMAT plans for midesophageal cancer. The target dose coverage in the SIB proton plans was less robust to random setup

    To determine the effectiveness of a psychosocial intervention, provided to expectant couples in routine antenatal classes, on the postpartum psychosocial adjustment of women and men. A 3*3 between subjects randomised control design was utilised. The two factors were condition and self-esteem. Preparation for Parenthood programs were randomly allocated to one of three conditions: usual service ('control'), experimental ('empathy'), or non-specific control ('baby-play'). The latter condition controlled for the non-specific effects of the intervention, these being: the provision of an extra class; asking couples to consider the early postpartum weeks; and receiving booster information after the antenatal class, and again shortly after the birth. Women and men were categorised into three levels of self-esteem, as measured antenatally: low, medium and high. 268 participants were recruited antenatally. Interview data and self-report information was collected from 202 of these women at 6 weeks postpartum, and 180 women at 6 months postpartum. The intervention consisted of a session focusing on psychosocial issues related to becoming first-time parents. Participants discussed possible postpartum concerns in separate gender groups for part of the session, and then discussed these issues with their partners. Hypothetical scenarios depicting stressful situations in the early postpartum weeks for women and men were discussed, with solutions that parents have found useful given to the participants. In the non-specific control condition, the session focused on the importance of play with a baby, with videotapes and discussion around how parents can play with infants. At 6 weeks postpartum there was a significant interaction effect between condition and self-esteem on maternal adjustment. Women with low self-esteem, who had received the intervention, were significantly better adjusted on measures of mood and sense of competence than low-self-esteem women in either of the two

    Full Text Available Após situar a homoparentalidade no contexto das novas práticas sociais e médicas referentes à filiação e à reprodução, o artigo apresenta um cenário do debate francês atual sobre essa questão. Serão nele confrontados os pensamentos de cinco psicanalistas: Joël Dor, e sua teorização sobre o papel da função paterna e da diferença anatômica entre os sexos na estruturação do sujeito; Pierre Legendre, e sua articulação entre os campos do jurídico e do psíquico na inscrição do ser humano na ordem da filiação; Michel Tort, e sua crítica às teorias de Legendre; Geneviève Delaisi de Parseval, e sua proposta de uma definição mais ampla da família; e, enfim, Sabine Prokhoris, e a sua distinção entre 'sexuação' e 'diferença dos sexos'. Através dessa apresentação, buscar-se-á desmontar os argumentos contrários e indicar a legitimidade da argumentação favorável à filiação homossexual.After situating homoparenthood within the context of the new social and medical practices concerning parenthood and reproduction, the article presents a scenario of the contemporary French debate on this issue. The thinking of five psychoanalysts on this matter will be broached : Joël Dor and his theory about the role of the function of the father and about the anatomic difference between sexes in the structure process of the subject; Pierre Legendre and his articulation between the fields of law and the psych in the involvement of the human being in the order of parenthood; Michel Tort and his criticism of the theories of that author; and Genevieve Delaisi de Parseval and her proposal of a broader definition of the family. And, finally, Sabine Prokhoris, and her distinction between "sexuation" and "difference of the sexes". This presentation intends to dismantle the opposite arguments and demonstrates the legitimacy of the reasoning favorable to homosexual parenthood.

    2002-01-01

    The FDA and the Spanish Ministry of Health have concluded that the risk/benefit ratio is favorable under certain circumstances for clinical studies investigating MDMA-assisted psychotherapy. Both agencies have approved pilot studies in chronic posttraumatic stress disorder (PTSD) patients who have failed to obtain relief from at least one course of conventional treatment. These studies, the only ones in the world into the therapeutic use of MDMA, are being funded by a nonprofit research and educational organization, the Multidisciplinary Association for Psychedelic Studies (MAPS, www.maps.org). A rationale is offered explaining why MAPS chose to focus its limited resources on MDMA, and also on PTSD patients. A Clinical Plan is elaborated for the conduct of the "adequate and well-controlled" trials necessary to evaluate the safety and efficacy of MDMA-assisted psychotherapy for PTSD, with the studies estimated to cost about 5 million dollars and to take about five years. The Clinical Plan has been developed, in part, through analysis of the studies conducted by Pfizer in its successful effort to have Zoloft approved by the FDA for use with PTSD patients, and through review of transcripts of the FDA's Psychopharmacologic Drugs Advisory Committee meeting that recommended approval of Zoloft for PTSD.

    Purpose: To present an automated technique for two-field tangential breast intensity-modulated radiotherapy (IMRT) treatment planning. Method and Materials: A total of 158 planned patients with Stage 0, I, and II breast cancer treated using whole-breast IMRT were retrospectively replanned using automated treatment planning tools. The tools developed are integrated into the existing clinical treatment planning system (Pinnacle 3 ) and are designed to perform the manual volume delineation, beam placement, and IMRT treatment planning steps carried out by the treatment planning radiation therapist. The automated algorithm, using only the radio-opaque markers placed at CT simulation as inputs, optimizes the tangential beam parameters to geometrically minimize the amount of lung and heart treated while covering the whole-breast volume. The IMRT parameters are optimized according to the automatically delineated whole-breast volume. Results: The mean time to generate a complete treatment plan was 6 min, 50 s ± 1 min 12 s. For the automated plans, 157 of 158 plans (99%) were deemed clinically acceptable, and 138 of 158 plans (87%) were deemed clinically improved or equal to the corresponding clinical plan when reviewed in a randomized, double-blinded study by one experienced breast radiation oncologist. In addition, overall the automated plans were dosimetrically equivalent to the clinical plans when scored for target coverage and lung and heart doses. Conclusion: We have developed robust and efficient automated tools for fully inversed planned tangential breast IMRT planning that can be readily integrated into clinical practice. The tools produce clinically acceptable plans using only the common anatomic landmarks from the CT simulation process as an input. We anticipate the tools will improve patient access to high-quality IMRT treatment by simplifying the planning process and will reduce the effort and cost of incorporating more advanced planning into clinical practice.

    In December 2016, the American Society of Clinical Oncology (ASCO) Board of Directors approved the ASCO Strategic Plan to Increase Racial and Ethnic Diversity in the Oncology Workforce. Developed through a multistakeholder effort led by the ASCO Health Disparities Committee, the purpose of the plan is to guide the formal efforts of ASCO in this area over the next three years (2017 to 2020). There are three primary goals: (1) to establish a longitudinal pathway for increasing workforce diversity, (2) to enhance ASCO leadership diversity, and (3) to integrate a focus on diversity across ASCO programs and policies. Improving quality cancer care in the United States requires the recruitment of oncology professionals from diverse backgrounds. The ASCO Strategic Plan to Increase Racial and Ethnic Diversity in the Oncology Workforce is designed to enhance existing programs and create new opportunities that will move us closer to the vision of achieving an oncology workforce that reflects the demographics of the US population it serves.

    Purpose: The aim of this study is to investigate the feasibility of using RapidPlan for breast cancer radiotherapy and to evaluate its performance for planners with different planning experiences. Methods: A training database was collected with 80 expert plan datasets from patients previously received left breast conserving surgery and IMRT-simultaneously integrated boost radiotherapy. The models were created on the RapidPlan. Five patients from the training database and 5 external patients were used for internal and external validation, respectively. Three planners with different planning experiences (beginner, junior, senior) designed manual and RapidPlan based plans for additional ten patients. The plan qualities were compared with manual and RapidPlan based ones. Results: For the internal and external validations, there were no significant dose differences on target coverage for plans from RapidPlan and manual. Also, no difference was found in the mean doses to contralateral breast and lung. The RapidPlan improved the heart (V5, V10, V20, V30, and mead dose) and ipsilateral lung (V5, V10, V20, V30, and mean dose) sparing for the beginner and junior planners. Compare to the plans from senior planner, 6 out of 16 clinically checked parameters were improved in RapidPlan, and the left parameters were similar. Conclusion: It is feasible to generate clinical acceptable plans using RapidPlan for breast cancer radiotherapy. The RapidPlan helps to systematically improve the quality of IMRT plans against the benchmark of clinically accepted plans. The RapidPlan shows promise for homogenizing plan quality by transferring planning expertise from more experienced to less experienced planners.

    Parental stress can negatively affect the parent-child relationship and reduce the well-being of the whole family. Family disagreement is associated with parental divorce and with psychological problems in children. The aim was to examine perceived parental stress and draw comparisons among mothers and among fathers, in relation to educational level, parental experience, existence of a parental role model and sense of coherence. The aim was also to examine perceived dyadic consensus and its association with perceived parental stress within couples. Questionnaires were completed by 320 mothers and 315 fathers at 1 week and 18 months post-partum. The Swedish Parenthood Stress Questionnaire, the Sense of Coherence Scale and the Dyadic Consensus Subscale were used. Low education, lack of a role model and poor sense of coherence promoted stress in mothers in the subareas social isolation and spouse relationship problems, while lack of a role model and poor sense of coherence promoted stress in fathers in the subarea social isolation. Furthermore, parental experiences promoted stress among mothers in the subarea incompetence while this was not seen among fathers. Mothers perceived a higher level of dyadic consensus than fathers in the items recreational activities, friends, aims and life goals, time spent together, and decisions regarding career and personal development. Household tasks was the only item where fathers perceived a higher level of dyadic consensus than mothers. Additionally, there were associations between perceived parental stress and dyadic consensus in several items and in the total score. To promote parents' health and family stability, health professionals should consider factors affecting stress and stress reactions, and take gender roles into account. © 2013 Nordic College of Caring Science.

    Multi-criteria optimization provides decision makers with a range of clinical choices through Pareto plans that can be explored during real time navigation and then converted into deliverable plans. Our study shows that dosimetric differences can arise between the two steps, which could compromise the clinical choices made during navigation. Copyright © 2016 Elsevier Ireland Ltd.

    Full Text Available Abstract Background In an attempt to devise a simpler computable tool to assist workforce planners in determining what might be an appropriate mix of health service skills, our discussion led us to consider the implications of skill mixing and workforce composition beyond the 'stock and flow' approach of much workforce planning activity. Methods Taking a dynamic systems approach, we were able to address the interactions, delays and feedbacks that influence the balance between the major components of health and health care. Results We linked clinical workforce requirements to clinical workforce workload, taking into account the requisite facilities, technologies, other material resources and their funding to support clinical care microsystems; gave recognition to productivity and quality issues; took cognisance of policies, governance and power concerns in the establishment and operation of the health care system; and, going back to the individual, gave due attention to personal behaviour and biology within the socio-political family environment. Conclusion We have produced the broad endogenous systems model of health and health care which will enable human resource planners to operate within real world variables. We are now considering the development of simple, computable national versions of this model.

    Background Different reasons influence the current low birth-rate and the postponement of the birth of the first child throughout Europe. The aim of this study was to explore how highly educated women and men in Sweden reflect on fertility and postponed parenthood. Methods We interviewed women (n = 22) and men (n = 18) who had started their professional careers and still had no children. Data were analysed with qualitative content analysis. Results Fertility was perceived as an unconsidered capacity, sometimes unpredictable, and different for women and men, but nevertheless taken for granted. The participants were of the opinion that fertility could be restored by assisted reproductive technologies or replaced by alternatives to a biological child. Postponed parenthood was described as an adaptation to societal changes and current discourses about parenthood as well as a consequence of a contemporary lifestyle with many competing priorities. Conclusion Highly educated young women and men in contemporary Sweden have competing priorities when planning and setting goals for their lives, and having children is one of them. They describe fertility as an imperceptible and retrievable capacity and postponed parenthood as a rational adaptation to changes in society. These findings suggest that increased information about the limitations of human reproduction is needed, but also that societal support for younger parents is of utmost importance. PMID:23305524

    Treatment planning is a central part of radiation therapy, including delineation in tumor volumes and critical organs, setting treatment goals of prescription doses to the tumor targets and tolerance doses to the critical organs, and finally generation of treatment plans to meet the treatment goals. National groups like RTOG have led the effort to standardize treatment goals of the prescription doses to the tumor targets and tolerance doses to the critical organs based on accumulated knowledge from decades of abundant clinical trial experience. The challenge for each clinical department is how to achieve or surpass these set goals within the time constraints of clinical practice. Using fifteen testing cases from different treatment sites such as head and neck, prostate with and without pelvic lymph nodes, SBRT spine, we will present clinically utility of advanced planning tools, including knowledge based, automatic based, and multiple criteria based tools that are clinically implemented. The objectives of this session are: Understand differences among these three advanced planning tools Provide clinical assessments on the utility of the advanced planning tools Discuss clinical challenges of treatment planning with large variations in tumor volumes and their relationships with adjacent critical organs.

    1989-04-01

    This article discusses the need for family planning (FP) as part of the development process, applauds its successes and rallies continued momentum of the FP movement. 500,000 women die each year from pregnancy- or labor-related conditions, and 10s of millions of women suffer pregnancy-related illnesses and impairments that undermine their social and economic productivity. Moreover, the 4 major factors that lead to high-risk pregnancies, namely, becoming pregnant before the age of 20, after the age of 35, after 4 or more pregnancies, and 2 years after an earlier pregnancy, all reveal the need for FP. These tragedies could be avoided by assuring better nutrition, primary health care for all, good antenatal attention and proper facilities and help in childbirth, access to good obstetric care in emergency situations, and universally available FP services. FP organizations must empower women with the knowledge of FP and the means to put it into practice. Developing countries, such as China, India, Indonesia, Thailand and Mexico, in addition to affluent industrialized countries have made strides in FP with the help of such organizations as the International Planned Parenthood Federation (IPPF). IPPF has helped to motivate large numbers of men and women to determine their ideal family size. It has provided the means for them to reach such goals and has ensured that acceptance of FP has been on a voluntary basis. IPPF has also advised and cajoled governments into becoming involved in FP. In the future, national strategies must produce the building blocks for better policies to help women become more responsible for their lives. The education of women will be vital to achieving this objective as well as other aspects of development.

    The association between family socioeconomic status (SES) and child executive functions is well-documented. However, few studies have examined the role of potential mediators and moderators. We studied the independent and interactive associations between family SES and single parenthood to predict child executive functions of inhibitory control, cognitive flexibility, and working memory and examined child expressive language abilities and family home environment as potential mediators of these associations. Sixty families from diverse SES backgrounds with a school-age target child (mean [SD] age = 9.9 [0.96] years) were evaluated. Child executive functioning was measured using a brief battery. The quality of the home environment was evaluated using the Home Observation for the Measurement of the Environment inventory. Family SES predicted the three child executive functions under study. Single parent and family SES were interactively associated with children's inhibitory control and cognitive flexibility; such that children from low SES families who were living with one parent performed less well on executive function tests than children from similarly low SES who were living with two parents. Parental responsivity, enrichment activities and family companionship mediated the association between family SES and child inhibitory control and working memory. This study demonstrates that family SES inequalities are associated with inequalities in home environments and with inequalities in child executive functions. The impact of these disparities as they unfold in the lives of typically developing children merits further investigation and understanding.

    One of the challenges of the coming years is to personalize medicine in order to provide each patient with an individualized treatment plan. The three objectives of personalized medicine are to refine diagnosis, rationalize treatment and engage patients in a preventive approach. Personalization can be characterized by various descriptors whether related to the field, biology, imaging, type of lesion of the entity to be treated, comorbidity factors, coprescriptions or the environment As part of personalized medicine focused on biological markers including genetics or genomics, the integration of the clinical development plan to obtain marketing authorization may be segmented in 3 stages with a known descriptor identified before clinical development, a known descriptor discovered during clinical development or a known descriptor known after clinical development. For each stage, it is important to clearly define the technical optimization elements, to specify the expectations and objectives, to examine the methodological aspects of each clinical development phase and finally to consider the fast changing regulatory requirements in view of the few registered therapeutics complying with the definition of personalized medicine as well as the significant technological breakthroughs according to the screened and selected biomarkers. These considerations should be integrated in view of the time required for clinical development from early phase to MA, i.e. more than 10 years. Moreover, business models related to the economic environment should be taken into account when deciding whether or not to retain a biomarker allowing the selection of target populations in a general population. © 2012 Société Française de Pharmacologie et de Thérapeutique.

    Purpose: Beam direction selection for fixed-beam IMRT planning is typically a manual process. Severe dose-volume limits on critical structures in the thorax often result in atypical selection of beam directions as compared to other body sites. This work demonstrates the potential consequences as well as clinical relevance. Methods: 21 thoracic cases treated with 5–7 beam directions, 6 cases including non-coplanar arrangements, with fractional doses of 150–411cGy were analyzed. Endpoints included per-beam modulation scaling factor (MSF), variation from equal weighting, and delivery QA passing rate. Results: During analysis of patient-specific delivery QA a sub-standard passing rate was found for a single 5-field plan (90.48% of pixels evaluated passing 3% dose, 3mm DTA). During investigation it was found that a single beam demonstrated a MSF of 34.7 and contributed only 2.7% to the mean dose of the target. In addition, the variation from equal weighting for this beam was 17.3% absolute resulting in another beam with a MSF of 4.6 contributing 41.9% to the mean dose to the target; a variation of 21.9% from equal weighting. The average MSF for the remaining 20 cases was 4.0 (SD 1.8) with an average absolute deviation of 2.8% from equal weighting (SD 3.1%). Conclusion: Optimization in commercial treatment planning systems typically results in relatively equally weighted beams. Extreme variation from this can result in excessively high MSFs (very small segments) and potential decreases in agreement between planned and delivered dose distributions. In addition, the resultant beam may contribute minimal dose to the target (quasi-dead beam); a byproduct being increased treatment time and associated localization uncertainties. Potential ramifications exist for automatic planning algorithms should they allow for user-defined beam directions. Additionally, these quasi-dead beams may be embedded in the libraries for model-based systems potentially resulting in inefficient

    By definition, forward planning is a process where input consists of conditions on beam configurations and parameters and output consists of dose distributions on target and critical structures, in contrast to inverse planning, where the opposite is true. For forward planning IMRT, criteria are as follows: (i) Plans created as an extension of standard 3D conformational planning; (ii) No significant increase in the complexity of the treatment planning or treatment delivery process; (3) Treatment verification using standard QA procedures; and process consists of the following steps: (i) Create a standard 3D conformational treatment plan; (ii) Copy one of the existing beams; (iii) Create control points: design new beam segments, blocking high dose areas; (iv) Repeat for all beams; (v) Re-compute dose; and (vi) Adjust control points weights to achieve desired dose distribution. A detailed exposition, with many clinical examples, is given for the breast, lung, and brain (P.A.)

    Half of a $10,000 grant was given by the International Planned Parenthood Federation (IPPF) to finance the rural development project activities of Danfa, a village of about 835 people in Ghana. In this community the women are hard working but doubly disadvantaged. Along with a high illiteracy rate, the women are limited by inadequate income due to underemployment, under productivity, unfavorable farming conditions, and a lack of resources. Large families, frequent pregnancies, poor mother and child health, and high infant mortality all make matters worse for both the rural farm wife and her family. The project began with a nucleus of women that soon grew to between 24-30. Members soon formed small groups according to their occupational interests. The women grasped the self-help idea immediately. Once or twice a month there were demonstrations and the group worked together in such activities as making soap and pomade, preparing meals, and sewing. Meetings generally ended with a general group brainstorming and then members gathered in smaller groups to review their activities and plan for the future. During the 1st year of the project the men in the group rarely attended meetings. The group gave priority attention to their community's urgent need for working capital. 15 women farmers who met the criteria determined by the group received loans in the 1st round; only 8 satisfied the criteria in the 2nd round. At the beginning of the small loans scheme, the group decided to seek bigger loans from the bank if members proved credit worthy. This requirement was satisfied, and the group began negotiations for a loan with the Agricultural Development Bank. The group received the total group loan. The Ghana Home Science Association considers the project to be successful in several respects. Team spirit has developed the group, and the women play important and respected roles. Family planning problems are regularly presented for discussion, but it is difficult to correlate

    Nurses have increasingly been regarded as critical members of the planning team as architects recognize their knowledge and value. But the nurses' role as knowledge experts can be expanded to leading efforts to integrate the clinical, operational, and architectural expertise through simulation modeling. Simulation modeling allows for the optimal merge of multifactorial data to understand the current state of the intensive care unit and predict future states. Nurses can champion the simulation modeling process and reap the benefits of a cost-effective way to test new designs, processes, staffing models, and future programming trends prior to implementation. Simulation modeling is an evidence-based planning approach, a standard, for integrating the sciences with real client data, to offer solutions for improving patient care.

    The study reported served 2 purposes: 1) to assess the amount of sexual information posessed by a sample of staff nurses working for the National Family Planning Board and the Public Health Dept., and 2) to gather local normative data on the Information Subtest of the Derogatis Sexual Functioning Inventory (DSFI). The subjects for the this study were 2 groups of staff nurses. 10 were employees of the National Family Planning Board currently working in 1 of its clinics and 25 were public health nurses who were at a 1 week training at the clinic. The research was a questionnaire type study. Each subject was given the DSFI. On the Information Subtest of the DSFI the subjects obtained a mean score of 12.7 with a standard deviation of 4.2. This score is much lower than the normative mean (American population) and the sexually dysfunctional women mean. The nurses had inadequate and inaccurate knowledge about anatomy, physiology and psychology of sexual relations. Error analysis revealed that as a group they had poor understanding about male sexuality, the effect of aging on sexuality fertility and menopause, and difficulty in accepting oral-genital sex and sexual fantasies. This study recommends that these nurses, in order to more effective in their work, should be trained in the area of human sexuality. This training must include not only the physiology of sex but also the human aspects of sexual union.

    Purpose: A new paradigm for treatment planning is proposed that embodies the concept of interactively exploring the space of optimized plans. In this approach, treatment planning ignores the details of individual plans and instead presents the physician with clinical summaries of sets of solutions to well-defined clinical goals in which every solution has been optimized in advance by computer algorithms. Methods and materials: Before interactive planning, sets of optimized plans are created for a variety of treatment delivery options and critical structure dose-volume constraints. Then, the dose-volume parameters of the optimized plans are fit to linear functions. These linear functions are used to show in real time how the target dose-volume histogram (DVH) changes as the DVHs of the critical structures are changed interactively. A bitmap of the space of optimized plans is used to restrict the feasible solutions. The physician selects the critical structure dose-volume constraints that give the desired dose to the planning target volume (PTV) and then those constraints are used to create the corresponding optimized plan. Results: The method is demonstrated using prototype software, Treatment Plan Explorer (TPEx), and a clinical example of a patient with a tumor in the right lung. For this example, the delivery options included 4 open beams, 12 open beams, 4 wedged beams, and 12 wedged beams. Beam directions and relative weights were optimized for a range of critical structure dose-volume constraints for the lungs and esophagus. Cord dose was restricted to 45 Gy. Using the interactive interface, the physician explored how the tumor dose changed as critical structure dose-volume constraints were tightened or relaxed and selected the best compromise for each delivery option. The corresponding treatment plans were calculated and compared with the linear parameterization presented to the physician in TPEx. The linear fits were best for the maximum PTV dose and worst

    Interprofessional health care team members consider advance care planning (ACP) to be important, yet gaps remain in systematic clinical routines to support ACP. A clearer understanding of the interprofessional team members' perspectives on ACP clinical routines in diverse settings is needed. One hundred eighteen health care team members from community-based clinics, long-term care facilities, academic clinics, federally qualified health centers, and hospitals participated in a 35-question, cross-sectional online survey to assess clinical routines, workflow processes, and policies relating to ACP. Respondents were 53% physicians, 18% advanced practice nurses, 11% nurses, and 18% other interprofessional team members including administrators, chaplains, social workers, and others. Regarding clinical routines, respondents reported that several interprofessional team members play a role in facilitating ACP (ie, physician, social worker, nurse, others). Most (62%) settings did not have, or did not know of, policies related to ACP documentation. Only 14% of settings had a patient education program. Two-thirds of the respondents said that addressing ACP is a high priority and 85% felt that nonphysicians could have ACP conversations with appropriate training. The clinical resources needed to improve clinical routines included training for providers and staff, dedicated staff to facilitate ACP, and availability of patient/family educational materials. Although interprofessional health care team members consider ACP a priority and several team members may be involved, clinical settings lack systematic clinical routines to support ACP. Patient educational materials, interprofessional team training, and policies to support ACP clinical workflows that do not rely solely on physicians could improve ACP across diverse clinical settings.

    Nigeria's contraceptive social marketing (CSM) project is ready to be launched. Population Services Intenational (PSI) had completed the groundwork for the project, funded primarily by a $200,000 grant from the nonpofit D.K. Tyagi Fund. The Population Crisis Committee also provided support for the new project. At presstime, PSI was negotiating for continued project funding from the US Agency for International Development (USAID) and The Futures Group. PSI already has identified suitable products, researched brand names, arranged for distribution, appointed an advertising agency, designed packaging, written a marketing plan, and taken steps to create a local, nonprofit marketing organization to manage the project. PSI has named Tim Barton as the resident manager. He will take up his post once the issue of future funding is resolved. Contraceptives now available are distributed through the private sector and by the Planned Parenthood Federation of Nigeria, the Local International Planned Parenthood Federation affiliate. Nigeria's annual rate of population growth is about 3% and the country is urbanizing rapidly. A 1983 fertility report revealed that only 14% of Nigerian women had ever used any type of contraception; 6% of married women were using a contraceptive method at the time of the survey.

    This study investigates the influence of multileaf collimator (MLC) leaf width on intensity modulated radiation therapy (IMRT) plans delivered via the segmented multileaf collimator (SMLC) technique. IMRT plans were calculated using the Corvus treatment planning system for three brain, three prostate, and three pancreas cases using leaf widths of 0.5 and 1 cm. Resulting differences in plan quality and complexity are presented here. Plans calculated using a 1 cm leaf width were chosen over the 0.5 cm leaf width plans in seven out of nine cases based on clinical judgment. Conversely, optimization results revealed a superior objective function result for the 0.5 cm leaf width plans in seven out of the nine comparisons. The 1 cm leaf width objective function result was superior only for very large target volumes, indicating that expanding the solution space for plan optimization by using narrower leaves may result in a decreased probability of finding the global minimum. In the remaining cases, we can conclude that we are often not utilizing the objective function as proficiently as possible to meet our clinical goals. There was often no apparent clinically significant difference between the two plans, and in such cases the issue becomes one of plan complexity. A comparison of plan complexity revealed that the average 1 cm leaf width plan required roughly 60% fewer segments and over 40% fewer monitor units than required by 0.5 cm leaf width plans. This allows a significant decrease in whole body dose and total treatment time. For very complex IMRT plans, the treatment delivery time may affect the biologically effective dose. A clinically significant improvement in plan quality from using narrower leaves was evident only in cases with very small target volumes or those with concavities that are small with respect to the MLC leaf width. For the remaining cases investigated in this study, there was no clinical advantage to reducing the MLC leaf width from 1 to 0.5 cm. In

    Radiosurgical treatment of brain metastases is well established in daily clinical routine. Utilization of flattening-filter-free beams (FFF) may allow for more rapid delivery of treatment doses and improve clinical comfort. Hence, we compared plan quality and efficiency of radiosurgery in FFF mode to FF techniques. Between November 2014 and June 2015, 21 consecutive patients with 25 brain metastases were treated with stereotactic radiosurgery (SRS) in FFF mode. Brain metastases received dose-fractionation schedules of 1 x 20 Gy or 1 x 18 Gy, delivered to the conformally enclosing 80 % isodose. Three patients with critically localized or large (>3 cm) brain metastases were treated with 6 x 5 Gy. Plan quality and efficiency were evaluated by analyzing conformity, dose gradients, dose to healthy brain tissue, treatment delivery time, and number of monitor units. FFF plans were compared to those using the FF method, and early clinical outcome and toxicity were assessed. FFF mode resulted in significant reductions in beam-on time (p < 0.001) and mean brain dose (p = 0.001) relative to FF-mode comparison plans. Furthermore, significant improvements in dose gradients and sharper dose falloffs were found for SRS in FFF mode (-1.1 %, -29.6 %; p ≤ 0.003), but conformity was slightly superior in SRS in FF mode (-1.3 %; p = 0.001). With a median follow-up time of 5.1 months, 6-month overall survival was 63.3 %. Local control was observed in 24 of 25 brain metastases (96 %). SRS in FFF mode is time efficient and provides similar plan quality with the opportunity of slightly reduced dose exposure to healthy brain tissue when compared to SRS in FF mode. Clinical outcomes appear promising and show only modest treatment-related toxicity. (orig.)

    The purpose of this article was to describe the workflow from imaging, via virtual design, to manufacturing of patient-specific titanium reconstruction plates, cutting guide and mesh, and its utility in connection with surgical treatment of acquired bone defects in the mandible using additive manufacturing by electron beam melting (EBM). Based on computed tomography scans, polygon skulls were created. Following that virtual treatment plans entailing free microvascular transfer of fibula flaps using patient-specific reconstruction plates, mesh, and cutting guides were designed. The design was based on the specification of a Compact UniLOCK 2.4 Large (Synthes(®), Switzerland). The obtained polygon plates were bent virtually round the reconstructed mandibles. Next, the resections of the mandibles were planned virtually. A cutting guide was outlined to facilitate resection, as well as plates and titanium mesh for insertion of bone or bone substitutes. Polygon plates and meshes were converted to stereolithography format and used in the software Magics for preparation of input files for the successive step, additive manufacturing. EBM was used to manufacture the customized implants in a biocompatible titanium grade, Ti6Al4V ELI. The implants and the cutting guide were cleaned and sterilized, then transferred to the operating theater, and applied during surgery. Commercially available software programs are sufficient in order to virtually plan for production of patient-specific implants. Furthermore, EBM-produced implants are fully usable under clinical conditions in reconstruction of acquired defects in the mandible. A good compliance between the treatment plan and the fit was demonstrated during operation. Within the constraints of this article, the authors describe a workflow for production of patient-specific implants, using EBM manufacturing. Titanium cutting guides, reconstruction plates for fixation of microvascular transfer of osteomyocutaneous bone grafts, and

    The CMS-HCC risk adjustment system for Medicare Advantage (MA) plans calculates weights, which are effectively relative prices, for beneficiaries with different observable characteristics. To do so it uses the relative amounts spent per beneficiary with those characteristics in Traditional Medicare (TM). For multiple reasons one might expect relative amounts in MA to differ from TM, thereby making some beneficiaries more profitable to treat than others. Much of the difference comes from differences in how TM and MA treat different diseases or diagnoses. Using data on actual medical spending from two MA-HMO plans, we show that the weights calculated from MA costs do indeed differ from those calculated using TM spending. One of the two plans (Plan 1) is more typical of MA-HMO plans in that it contracts with independent community providers, while the other (Plan 2) is vertically integrated with care delivery. We calculate margins, or Average Revenue/Average Cost, for Medicare beneficiaries in the two plans who have one of 48 different combinations of medical conditions. The two plans’ margins for these 48 conditions are correlated (r=0.39, pincentive for selection by HCC. Nonetheless, we find no evidence of overrepresentation of beneficiaries in high margin HCC’s in either plan. Nor, using the margins from Plan 1, the more typical plan, do we find evidence of overrepresentation of high margin HCC’s in Medicare more generally. These results do not permit a conclusion on overall social efficiency, but we note that selection according to margin could be socially efficient. In addition, our findings suggest there are omitted interaction terms in the risk adjustment model that Medicare currently uses. PMID:24308879

    This study evaluates the performance and planning efficacy of the Auto-Planning (AP) module in the clinical version of Pinnacle 9.10 (Philips Radiation Oncology Systems, Fitchburg, WI, USA). Twenty automated intensity-modulated radiotherapy (IMRT) plans were compared with the original manually planned clinical IMRT plans from patients with oropharyngeal cancer. Auto-Planning with IMRT offers similar coverage of the planning target volume as the original manually planned clinical plans, as well as better sparing of the contralateral parotid gland, contralateral submandibular gland, larynx, mandible, and brainstem. The mean dose of the contralateral parotid gland and contralateral submandibular gland could be reduced by 2.5 Gy and 1.7 Gy on average. The number of monitor units was reduced with an average of 143.9 (18%). Hands-on planning time was reduced from 1.5-3 h to less than 1 h. The Auto-Planning module was able to produce clinically acceptable head and neck IMRT plans with consistent quality. (orig.) [de

    A review of the literature is proposed as a contribution to current knowledge on technical, physical, and clinical issues about PET-guided planning and re-planning radiotherapy (RT) in head and neck cancer. PubMed and Scopus electronic databases were searched for articles including clinical trials. Search terms were "gross tumor volume (GTV) delineation", "head and neck cancer", "radiotherapy", "adaptive radiotherapy" in combination with "PET". A 18 F-FDG-PET and CT-scan comparison in GTV definition for RT planning of head and neck cancer was shown in twenty-seven clinical trials with a total of 712 patients. Only two clinical trials focused on PET-guided adaptive radiotherapy (ART) with a total of 31 patients. 18 F-FDG-PET is able to achieve an accurate and precise definition of GTV boundaries during RT planning, especially in combination with CT-scan. ART strategies are proposed to evaluate tumor volume changes, plan boost irradiation on metabolically active residual neoplasm and protect organs at risk (OaRs).

    The Radiation Planning Assistant (RPA) is a system developed for the fully automated creation of radiotherapy treatment plans, including volume-modulated arc therapy (VMAT) plans for patients with head/neck cancer and 4-field box plans for patients with cervical cancer. It is a combination of specially developed in-house software that uses an application programming interface to communicate with a commercial radiotherapy treatment planning system. It also interfaces with a commercial secondary dose verification software. The necessary inputs to the system are a Treatment Plan Order, approved by the radiation oncologist, and a simulation computed tomography (CT) image, approved by the radiographer. The RPA then generates a complete radiotherapy treatment plan. For the cervical cancer treatment plans, no additional user intervention is necessary until the plan is complete. For head/neck treatment plans, after the normal tissue and some of the target structures are automatically delineated on the CT image, the radiation oncologist must review the contours, making edits if necessary. They also delineate the gross tumor volume. The RPA then completes the treatment planning process, creating a VMAT plan. Finally, the completed plan must be reviewed by qualified clinical staff.

    This study examined the antecedents and determinants predictive of whether nursing students (N = 92) intend to ask for assignments to perform nursing behaviors after using a database to record essential clinical behaviors. The results of applying the theory of planned behavior (TPB) to behavioral intention using multivariant path analysis suggested that the endogenous variables, attitude and subjective norms, had a significant effect on the intention to ask for assignments to perform nursing behaviors. In addition, it was primarily through attitudes and subjective norms that the respective antecedents or exogenous variables, behavioral beliefs and normative beliefs, affected the intention to ask for assignments to perform nursing behaviors. The lack of direct influence of perceived behavioral control on intention and the direct negative impact of control belief on intention were contrary to expectations, given the tenets of the TPB.

  18. Trade-off bounds for the Pareto surface approximation in multi-criteria IMRT planning

    2009-01-01

    One approach to multi-criteria IMRT planning is to automatically calculate a data set of Pareto-optimal plans for a given planning problem in a first phase, and then interactively explore the solution space and decide on the clinically best treatment plan in a second phase. The challenge of computing the plan data set is to ensure that all clinically meaningful plans are covered and that as many clinically irrelevant plans as possible are excluded to keep computation times within reasonable limits. In this work, we focus on the approximation of the clinically relevant part of the Pareto surface, the process that constitutes the first phase. It is possible that two plans on the Pareto surface have a small, clinically insignificant difference in one criterion and a significant difference in another criterion. For such cases, only the plan that is clinically clearly superior should be included into the data set. To achieve this during the Pareto surface approximation, we propose to introduce bounds that restrict the relative quality between plans, the so-called trade-off bounds. We show how to integrate these trade-off bounds into the approximation scheme and study their effects. The proposed scheme is applied to two artificial cases and one clinical case of a paraspinal tumor. For all cases, the quality of the Pareto surface approximation is measured with respect to the number of computed plans, and the range of values occurring in the approximation for different criteria is compared. Through enforcing trade-off bounds, the scheme disregards clinically irrelevant plans during the approximation. Thereby, the number of plans necessary to achieve a good approximation quality can be significantly reduced. Thus, trade-off bounds are an effective tool to focus the planning and to reduce computation time.

    2016-06-15

    Purpose: High Dose Rate (HDR) brachytherapy forward planning is principally an iterative process; hence, plan quality is affected by planners’ experiences and limited planning time. Thus, this may lead to sporadic errors and inconsistencies in planning. A statistical tool based on previous approved clinical treatment plans would help to maintain the consistency of planning quality and improve the efficiency of second checking. Methods: An independent dose calculation tool was developed from commercial software. Thirty-three previously approved cervical HDR plans with the same prescription dose (550cGy), applicator type, and treatment protocol were examined, and ICRU defined reference point doses (bladder, vaginal mucosa, rectum, and points A/B) along with dwell times were collected. Dose calculation tool then calculated appropriate range with a 95% confidence interval for each parameter obtained, which would be used as the benchmark for evaluation of those parameters in future HDR treatment plans. Model quality was verified using five randomly selected approved plans from the same dataset. Results: Dose variations appears to be larger at the reference point of bladder and mucosa as compared with rectum. Most reference point doses from verification plans fell between the predicted range, except the doses of two points of rectum and two points of reference position A (owing to rectal anatomical variations & clinical adjustment in prescription points, respectively). Similar results were obtained for tandem and ring dwell times despite relatively larger uncertainties. Conclusion: This statistical tool provides an insight into clinically acceptable range of cervical HDR plans, which could be useful in plan checking and identifying potential planning errors, thus improving the consistency of plan quality.

Participaram quarenta e sete casais que esperavam seu primeiro filho, entrevistados conjuntamente no último trimestre da gravidez. Os resultados, analisados através de análise de conteúdo, mostraram que a maior parte dos casais (53% relatou ter tido ritual de casamento e ter planejado a primeira gravidez, enquanto 25% dos casais não relataram nenhuma das duas situações. Desta maneira, constatou-se uma associação estatisticamente significativa entre a presença de ritual de casamento e o planejamento da gravidez do primeiro filho. Os resultados apóiam a expectativa inicial de que o modo como ocorre a transição para o casamento desempenha um papel importante no planejamento da primeira gravidez. O ritual de casamento claramente demarca o início de um novo núcleo familiar, a passagem para a adultez e a potencial transição para a parentalidade.This study investigated the existence of a marriage ritual and the planning of a first-child. Forty-seven couples, who were expecting their first child were interviewed jointly in the last trimester of pregnancy. The results, obtained from content analysis, showed that most couples (53% reported that they had had a marriage ritual and that they had planned the first pregnancy, while 25% of the couples did not report any of the two situations. Therefore a statistically significant association was found between the presence of a marriage ritual and the first-child planning. The results gave support to the initial expectation that the way the transition to marriage takes place, has an important role in the first-child planning. Marriage rituals clearly demarcate the beginning of a new family, the transition to adulthood and the potential transition to parenthood.

    HDR intraoperative brachytherapy (IOBT) is applied to locally advanced rectal tumors using a 5 mm thick flexible intraoperative template (FIT). To reduce the procedure time, treatment planning is performed using standard plans that neglect the curvature of the FIT. We have calculated the individual treatment plan, based on the real geometry of the FIT, and the dose at clips placed during surgery. A mean treatment dose of 9.55±0.21 Gy was found for the individual plan, compared to the prescribed 10 Gy (P<0.0001). The mean central dose was 10.03±0.10 Gy in the standard plan and 9.20±0.32 Gy in the individual plan (P<0.0001). The mean dose at the corners of the FIT was 10.3 Gy in the standard plan and ranged between 10.3 and 10.5 Gy in the individual plan. In 63% of the clips, the dose was larger than 15.0 Gy, which is equivalent to a gap between the FIT and the target smaller than 5 mm. In 18% of the clips, the dose was smaller than 13.0 Gy indicating that locally the gap was larger than 5 mm. Clinical practice will have to prove if these small dose deviations influence the clinical outcome

    A Paediatric Investigation Plan (PIP) is a development plan that aims to ensure that sufficient data are obtained through studies in paediatrics to support the generation of marketing authorisation of medicines for children. This paper highlights some practical considerations and challenges with respect to PIP submissions and paediatric clinical trials during the pharmaceutical development phase, using the FP7-funded Clonidine for Sedation of Paediatric Patients in the Intensive Care Unit (CloSed) project as a case study. Examples discussed include challenges and considerations regarding formulation development, blinding and randomisation, product labelling and shipment and clinical trial requirements versus requirements for marketing authorisation. A significant quantity of information is required for PIP submissions and it is hoped that future applicants may benefit from an insight into some critical considerations and challenges faced in the CloSed project.

    Radiotherapy often comprises two phases, in which irradiation of a volume at risk for microscopic disease is followed by a sequential dose escalation to a smaller volume either at a higher risk for microscopic disease or containing only gross disease. This technique is difficult to implement with intensity modulated radiotherapy, as the tolerance doses of critical structures must be respected over the sum of the two plans. Techniques that include an integrated boost have been proposed to address this problem. However, clinical experience with such techniques is limited, and many clinicians are uncomfortable prescribing nonconventional fractionation schemes. To solve this problem, we developed an optimization technique that simultaneously generates sequential initial and boost IMRT plans. We have developed an optimization tool that uses a commercial treatment planning system (TPS) and a high level programming language for technical computing. The tool uses the TPS to calculate the dose deposition coefficients (DDCs) for optimization. The DDCs were imported into external software and the treatment ports duplicated to create the boost plan. The initial, boost, and tolerance doses were specified and used to construct cost functions. The initial and boost plans were optimized simultaneously using a gradient search technique. Following optimization, the fluence maps were exported to the TPS for dose calculation. Seven patients treated using sequential techniques were selected from our clinical database. The initial and boost plans used to treat these patients were developed independently of each other by dividing the tolerance doses proportionally between the initial and boost plans and then iteratively optimizing the plans until a summation that met the treatment goals was obtained. We used the simultaneous optimization technique to generate plans that met the original planning goals. The coverage of the initial and boost target volumes in the simultaneously optimized

    In recent years, PET and PET/CT have well been established for staging and restaging of various malignancies. Increasingly, the modality is also used for radiotherapy treatment planning. However, clinical studies investigating the patients benefit by the inclusion of those modalities into RT treatment planning are mandatory, simultaneously defining standards for future care. Chances and problems of such studies are discussed using the examples of the PET-Plan and GLIAA trials. (orig.)

    Purpose: The aim of this work was to develop a treatment planning workflow for rapid radiotherapy delivered with very high-energy electron (VHEE) scanning pencil beams of 60–120 MeV and to study VHEE plans as a function of VHEE treatment parameters. Additionally, VHEE plans were compared to clinical state-of-the-art volumetric modulated arc therapy (VMAT) photon plans for three cases. Methods: VHEE radiotherapy treatment planning was performed by linking EGSnrc Monte Carlo (MC) dose calculations with inverse treatment planning in a research version of RayStation. In order to study the effect of VHEE treatment parameters on VHEE dose distributions, a MATLAB graphical user interface (GUI) for calculation of VHEE MC pencil beam doses was developed. Through the GUI, pediatric case MC simulations were run for a number of beam energies (60, 80, 100, and 120 MeV), number of beams (13, 17, and 36), pencil beam spot (0.1, 1.0, and 3.0 mm) and grid (2.0, 2.5, and 3.5 mm) sizes, and source-to-axis distance, SAD (40 and 50 cm). VHEE plans for the pediatric case calculated with the different treatment parameters were optimized and compared. Furthermore, 100 MeV VHEE plans for the pediatric case, a lung, and a prostate case were calculated and compared to the clinically delivered VMAT plans. All plans were normalized such that the 100% isodose line covered 95% of the target volume. Results: VHEE beam energy had the largest effect on the quality of dose distributions of the pediatric case. For the same target dose, the mean doses to organs at risk (OARs) decreased by 5%–16% when planned with 100 MeV compared to 60 MeV, but there was no further improvement in the 120 MeV plan. VHEE plans calculated with 36 beams outperformed plans calculated with 13 and 17 beams, but to a more modest degree (<8%). While pencil beam spacing and SAD had a small effect on VHEE dose distributions, 0.1–3 mm pencil beam sizes resulted in identical dose distributions. For the 100 MeV VHEE pediatric

  11. The structure of contraceptive education and instruction within nurse led family planning clinics: a grounded theory study.

    2009-09-01

    This study aimed to explore and analyse how nurses instruct women in contraceptive use during consultations in family planning clinics to produce a grounded theory of contraceptive education. Nurses play a key role in instructing women how to use contraception in family planning clinic consultations. These one-to-one situations are encounters where women are taught how to use contraceptive methods effectively. However, very little is known about the nature of these consultations. A qualitative study using a grounded theory approach was used. Three linked 'core categories' emerged from the data analysis. Firstly, women are educated about their body and how it responds to contraception: 'reproductive education'. This core category is closely linked to 'surveillance' where women are taught to monitor their reproductive health and to 'contraceptive regimen' where women are instructed in techniques to successfully use a contraceptive method. Together these three core categories present a grounded theory of 'contraceptive education'. Nursing practice in this important area of women's health care is complex and requires skilled practitioners. This study presents unique empirical data into how nurses conduct one-to-one consultations with women - providing a novel insight into how contraception is explained in clinical situations. Key issues for practice from the data were the lack of a balance when discussing side effects, the rigidity of some instructions and the lack of recognition of risk from sexually transmitted infection. Nurses working in sexual health need to ensure that women understand the often complex instructions they provide and that rigid instruction be occasionally amended to enable some flexibility. The manner in which side-effects are discussed should also be balanced. Nurses need to address the risk of sexually transmitted infections more substantially in contraceptive discussions.

    The purpose of the study reported in this article was to examine how the unique circumstances of the birth of a premature baby affect the perception of parental self-efficacy and stress-related growth--which is the experience of positive change in one's life following stressful circumstances--among first-time parents and to examine the contribution of the parents' personal resources of self-esteem and attachment style, and their infant's temperament and medical condition, to their self-efficacy and stress-related growth. Forty-nine sets of parents of preterm babies and 50 sets of parents of full-term babies completed questionnaires about one month after the birth of their child. Parents of premature infants reported a higher level of stress-related growth than those of full-term infants, but no difference was found between them on parental self-efficacy In addition, gender differences in the dependent variables, as well as significant contributions of attachment style and self-esteem, were found. Professional guidance during pregnancy, aimed at expanding parents' knowledge and understanding of the changes they can expect to undergo, may serve to enhance the positive experience of growth in the transition to parenthood.

    To investigate various issues for clinical implementation of aSi EPID panels for IMRT/VMAT QA. Six linacs are used in our clinic for EPID-based plan QA; two Varian Truebeams, two Varian 2100 series, two Elekta Infiniti series. Multiple corrections must be accounted for in the calibration of each panel for dosimetric use. Varian aSi panels are calibrated with standard dark field, flood field, and 40×40 diagonal profile for beam profile correction. Additional corrections to account for off-axis and support arm backscatter are needed for larger field sizes. Since Elekta iViewGT system does not export gantry angle with images, a third-party inclinometer must be physically mounted to back of linac gantry and synchronized with data acquisition via iViewGT PC clock. A T/2 offset correctly correlates image and gantry angle for arc plans due to iView image time stamp at the end of data acquisition for each image. For both Varian and Elekta panels, a 5 MU 10×10 calibration field is used to account for the nonlinear MU to dose response at higher energies. Acquired EPID images are deconvolved via a high pass filter in Fourier space and resultant fluence maps are used to reconstruct a 3D dose 'delivered' to patient using DosimetryCheck. Results are compared to patient 3D dose computed by TPS using a 3D-gamma analysis. 120 IMRT and 100 VMAT cases are reported. Two 3D gamma quantities (Gamma(V10) and Gamma(PTV)) are proposed for evaluating QA results. The Gamma(PTV) is sensitive to MLC offsets while Gamma(V10) is sensitive to gantry rotations. When a 3mm/3% criteria and 90% or higher 3D gamma pass rate is used, all IMRT and 90% of VMAT QA pass QA. After appropriate calibration of aSi panels and setup of image acquisition systems, EPID based 3D dose reconstruction method is found clinically feasible. © 2012 American Association of Physicists in Medicine.

    Reproductive and sexual health (RSH) education is a key component of most family planning programs around the world and is particularly important for adolescents, for whom parenthood is more likely to have difficult or dangerous health outcomes. A lack of comprehensive RSH education targeted at adolescents may augment the poor outcomes associated with early pregnancy by creating barriers to optimal care. This article discusses the creation of the Centro de Medicina Reproductiva y Desarrollo Integral de la Adolescencia clinic, a comprehensive adolescent reproductive health center in Santiago de Chile, and its RSH education programs. In particular, the role of the physician in originating and leading the RSH education efforts, the controversy associated with RSH education in Chile, and the effects of comprehensive RHS education on the local and regional adolescent populations are discussed.

    To assess the relationships between delinquency and demographic and family variables, academic performance, war stressors, home/community, school, and media violence exposure, self-image, and psychopathology. This cross-sectional study included 100 delinquent, incarcerated male adolescents and 100 matched schoolchildren from Croatia. It lasted from January 2008 to June 2009, and used socio-demographic questionnaire, questionnaire on children's stressful and traumatic war experiences, exposure to violence scale, the Offer Self-Image Questionnaire, and Youth Self-Report Questionnaire. Logistic regression analysis showed that delinquency in incarcerated adolescents was more likely related to having parents who did not live together (odds ratio [OR] 2.40; confidence interval [CI] 1.18-4.90, P=0.015), being more exposed to violence at home/community (OR 3.84; CI 1.58-9.34, P=0.003), and having poorer self-image (OR 1.09; CI=1.03-1.16, P>0.002). Preventive and therapeutic interventions in incarcerated delinquents should be specifically targeted toward single parenthood, family factors, trauma oriented interventions, and focused on multiple dimensions of self-concept of adolescents.

  17. Applications of NTCP calculations to treatment planning

    A fundamental step in the treatment decision process is the evaluation of a treatment plan. Most often treatment plans are judged by tradition using guidelines like target homogeneity and maximum dose to non-target tissues. While such judgments implicitly assume a relationship between dose distribution parameters and patient response, the judgment process is essentially supported by clinical outcomes from previous treatments. With the development of conformal therapy, new and unusual dose distributions and escalated doses are possible, while the clinical consequences are unknown. this situation has instigated attempts to place plan evaluation on a more systematic platform. One such endeavor has centered around attempts to calculate normal tissue complication probability (NTCP) and its sibling, tumor control probability (TCP). This lecture will be composed of two parts. The first will begin with a review of two categories of NTCP models: (1) an 'empirical' approach, based upon a power-law relationship between partial organ tolerance and irradiated volume, and histogram reduction to account for inhomogeneous irradiation: (2) a 'statistical' approach in which local responses are combined according to the underlying tissue architecture. Since both rely upon clinical data - often of limited and questionable validity - we will review some examples from the clinical and biological literature. The second part of the lecture will review clinical applications of biological-index based models: ranking competing treatment plans; design of dose escalation protocols; optimization of treatment plans with intensity modulation. We will also demonstrate how biological indices can be used to derive dose-volume histograms which account for treatment uncertainty

    To develop a fully automated procedure for multicriterial volumetric modulated arc therapy (VMAT) treatment planning (autoVMAT) for stage III/IV non-small cell lung cancer (NSCLC) patients treated with curative intent. After configuring the developed autoVMAT system for NSCLC, autoVMAT plans were compared with manually generated clinically delivered intensity-modulated radiotherapy (IMRT) plans for 41 patients. AutoVMAT plans were also compared to manually generated VMAT plans in the absence of time pressure. For 16 patients with reduced planning target volume (PTV) dose prescription in the clinical IMRT plan (to avoid violation of organs at risk tolerances), the potential for dose escalation with autoVMAT was explored. Two physicians evaluated 35/41 autoVMAT plans (85%) as clinically acceptable. Compared to the manually generated IMRT plans, autoVMAT plans showed statistically significant improved PTV coverage (V_9_5_% increased by 1.1% ± 1.1%), higher dose conformity (R_5_0 reduced by 12.2% ± 12.7%), and reduced mean lung, heart, and esophagus doses (reductions of 0.9 Gy ± 1.0 Gy, 1.5 Gy ± 1.8 Gy, 3.6 Gy ± 2.8 Gy, respectively, all p [de

    To examine professional stigma and attitudes of parenthood towards postpartum women with severe mental illness and the association between postpartum nurses' attitudes and nursing interventions that promote motherhood. Stigma and attitudes towards parenthood of women with severe mental illness may influence nurses' clinical practices. Cross-sectional, mixed methods. The Stigma among Health Professionals towards People with Severe Mental Illness, Attitudes towards Parenthood among People with Severe Mental Illness and Nursing Interventions that Promote Becoming a Mother Questionnaires were used in the study, as well as qualitative analysis. Sixty-one postpartum nurses participated in the study. Increased stigma was associated with an increase in negative attitudes towards parenthood among people with severe mental illness, in general, and towards their parenthood skills, in particular. Postpartum nurses reported a decrease in nursing interventions and a therapeutic nurse-client relationship that fosters mother's empowerment. Themes that emerged from the qualitative analysis were postpartum nurse's perceptions of inadequacy, difficulty of postpartum nurses taking responsibility for managing women with severe mental illness and a paternalistic approach to these women, rather than empowerment, regarding infant care. Nurses providing care to postpartum women with severe mental illness and their infants may provide fewer routine postpartum interventions due to professional stigma and negative attitudes concerning parenting skills. Nurses should provide individualised, tailored care that allows women with severe mental illness to become a mother to the best of her ability. Not all women with severe mental illness are capable of caring for themselves and/or their baby. Nurses should provide individualised, tailored care that allows the women with severe mental illness to become a mother to the best of her ability. © 2017 John Wiley & Sons Ltd.

    2003-01-01

    A fuzzy logic technique was applied to optimize the weighting factors in the objective function of an inverse treatment planning system for intensity-modulated radiation therapy (IMRT). Based on this technique, the optimization of weighting factors is guided by the fuzzy rules while the intensity spectrum is optimized by a fast-monotonic-descent method. The resultant fuzzy logic guided inverse planning system is capable of finding the optimal combination of weighting factors for different anatomical structures involved in treatment planning. This system was tested using one simulated (but clinically relevant) case and one clinical case. The results indicate that the optimal balance between the target dose and the critical organ dose is achieved by a refined combination of weighting factors. With the help of fuzzy inference, the efficiency and effectiveness of inverse planning for IMRT are substantially improved

    Full Text Available Abstract Background A physically active life promotes both physical and mental health, increasing well-being and quality of life. Physical activity (PA performed outdoors has been found to be particularly good for promoting well-being. However, participation in PA can change during the course of a lifetime. Parenthood has been found to be a life event associated with decreased PA, especially among women, although studies in the field are sparse. The aim of this study was to investigate participation in outdoor recreational PA, and factors influencing participation among parents-to-be, with and without previous children, from a gender perspective. Methods This study included baseline data from parents-to-be, 224 women and 208 men, from the municipality of Karlskrona in south-east Sweden. Data collection was carried out during 2008-2009. We measured the self-reported amount of outdoor recreational PA undertaken during the last year and analysed the probability of participating in this PA using 25 variables covering individual and socioeconomic factors. Results Seventy-six per cent of the women and 65% of the men had participated in outdoor recreational PA, varying from several times per month to every day, over a 12-month period prior to one month before pregnancy. Participation in PA indoors and owning a dog or a horse emerged as the most important factors associated with the probability of participation in outdoor recreational PA. Men were affected by a greater number of factors than women, for example men who had a family situation that permitted outdoor recreational PA participated in activities to a greater extent than men without such a family situation. The physical aspect, i.e. improved physical condition, staying power and vigour, also played a significant role with regard to participation among men. Conclusions Becoming a parent is a life-changing event that affects participation in PA. By offering family-oriented PA choices that involve

    Adaptive radiation therapy (ART) can reduce normal tissue toxicity and/or improve tumor control through treatment adaptations based on the current patient anatomy. Developing an efficient and effective re-planning algorithm is an important step toward the clinical realization of ART. For the re-planning process, manual trial-and-error approach to fine-tune planning parameters is time-consuming and is usually considered unpractical, especially for online ART. It is desirable to automate this step to yield a plan of acceptable quality with minimal interventions. In ART, prior information in the original plan is available, such as dose–volume histogram (DVH), which can be employed to facilitate the automatic re-planning process. The goal of this work is to develop an automatic re-planning algorithm to generate a plan with similar, or possibly better, DVH curves compared with the clinically delivered original plan. Specifically, our algorithm iterates the following two loops. An inner loop is the traditional fluence map optimization, in which we optimize a quadratic objective function penalizing the deviation of the dose received by each voxel from its prescribed or threshold dose with a set of fixed voxel weighting factors. In outer loop, the voxel weighting factors in the objective function are adjusted according to the deviation of the current DVH curves from those in the original plan. The process is repeated until the DVH curves are acceptable or maximum iteration step is reached. The whole algorithm is implemented on GPU for high efficiency. The feasibility of our algorithm has been demonstrated with three head-and-neck cancer IMRT cases, each having an initial planning CT scan and another treatment CT scan acquired in the middle of treatment course. Compared with the DVH curves in the original plan, the DVH curves in the resulting plan using our algorithm with 30 iterations are better for almost all structures. The re-optimization process takes about 30

    2018-03-13

    This article investigates dose-volume prediction improvements in a common knowledge-based planning (KBP) method using a Pareto plan database compared with using a conventional, clinical plan database. Two plan databases were created using retrospective, anonymized data of 124 volumetric modulated arc therapy (VMAT) prostate cancer patients. The clinical plan database (CPD) contained planning data from each patient's clinically treated VMAT plan, which were manually optimized by various planners. The multicriteria optimization database (MCOD) contained Pareto-optimal plan data from VMAT plans created using a standardized multicriteria optimization protocol. Overlap volume histograms, incorporating fractional organ at risk volumes only within the treatment fields, were computed for each patient and used to match new patient anatomy to similar database patients. For each database patient, CPD and MCOD KBP predictions were generated for D 10 , D 30 , D 50 , D 65 , and D 80 of the bladder and rectum in a leave-one-out manner. Prediction achievability was evaluated through a replanning study on a subset of 31 randomly selected database patients using the best KBP predictions, regardless of plan database origin, as planning goals.

    Purpose: To develop and evaluate fully automated volumetric modulated arc therapy (VMAT) treatment planning for prostate cancer patients, avoiding manual trial-and-error tweaking of plan parameters by dosimetrists. Methods and Materials: A system was developed for fully automated generation of VMAT plans with our commercial clinical treatment planning system (TPS), linked to the in-house developed Erasmus-iCycle multicriterial optimizer for preoptimization. For 30 randomly selected patients, automatically generated VMAT plans (VMAT auto ) were compared with VMAT plans generated manually by 1 expert dosimetrist in the absence of time pressure (VMAT man ). For all treatment plans, planning target volume (PTV) coverage and sparing of organs-at-risk were quantified. Results: All generated plans were clinically acceptable and had similar PTV coverage (V 95%  > 99%). For VMAT auto and VMAT man plans, the organ-at-risk sparing was similar as well, although only the former plans were generated without any planning workload. Conclusions: Fully automated generation of high-quality VMAT plans for prostate cancer patients is feasible and has recently been implemented in our clinic

    Purpose: To demonstrate the large-scale clinical implementation and performance of an automated treatment planning methodology for tangential breast intensity modulated radiation therapy (IMRT). Methods and Materials: Automated planning was used to prospectively plan tangential breast IMRT treatment for 1661 patients between June 2009 and November 2012. The automated planning method emulates the manual steps performed by the user during treatment planning, including anatomical segmentation, beam placement, optimization, dose calculation, and plan documentation. The user specifies clinical requirements of the plan to be generated through a user interface embedded in the planning system. The automated method uses heuristic algorithms to define and simplify the technical aspects of the treatment planning process. Results: Automated planning was used in 1661 of 1708 patients receiving tangential breast IMRT during the time interval studied. Therefore, automated planning was applicable in greater than 97% of cases. The time for treatment planning using the automated process is routinely 5 to 6 minutes on standard commercially available planning hardware. We have shown a consistent reduction in plan rejections from plan reviews through the standard quality control process or weekly quality review multidisciplinary breast rounds as we have automated the planning process for tangential breast IMRT. Clinical plan acceptance increased from 97.3% using our previous semiautomated inverse method to 98.9% using the fully automated method. Conclusions: Automation has become the routine standard method for treatment planning of tangential breast IMRT at our institution and is clinically feasible on a large scale. The method has wide clinical applicability and can add tremendous efficiency, standardization, and quality to the current treatment planning process. The use of automated methods can allow centers to more rapidly adopt IMRT and enhance access to the documented

    The purpose of this book is to explore in ten empirical chapters how good parenthood is done in different contexts, by different agents. The introductory chapter outlines the theoretical implications of viewing parenthood as a series of practices and our interest in the enactment and negotiation...... of good parenthood. We argue that the doing of good parenthood should be studied empirically and in context. Therefore, the particularities of Denmark and Sweden as contexts are briefly introduced. Finally, we argue that parenthood is to be understood in relation to childhood, and the doing of good...... parenthood should be situated in relation to notions of children’s interests and rights. Therefore, the book is anchored in the research fields of both parenting studies and child studies....

    Using a Standardized Clinical Assessment and Management Plan (SCAMP) for pediatric patients presenting to clinic with chest pain, we evaluated the cost impact associated with implementation of the care algorithm. Prior to introduction of the SCAMP, we analyzed charges for 406 patients with chest pain, seen in 2009, and predicted 21% reduction of overall charges had the SCAMP methodology been used. The SCAMP recommended an echocardiogram for history, examination, or ECG findings suggestive of a cardiac etiology for chest pain. Resource utilization was reviewed for 1517 patients (7-21 years) enrolled in the SCAMP from July 2010 to April 2014. Compared to the 2009 historic cohort, patients evaluated by the SCAMP had higher rates of exertional chest pain (45% vs 37%) and positive family history (5% vs 1%). The SCAMP cohort had fewer abnormal physical examination findings (1% vs 6%) and abnormal electrocardiograms (3% vs 5%). Echocardiogram use increased in the SCAMP cohort compared to the 2009 historic cohort (45% vs 41%), whereas all other ancillary testing was reduced: exercise stress testing (4% SCAMP vs 28% historic), Holter (4% vs 7%), event monitors (3% vs 10%), and MRI (1% vs 2%). Total charges were reduced by 22% ($822 625) by use of the Chest Pain SCAMP, despite a higher percentage of patients for whom echocardiogram was recommended compared to the historic cohort. The Chest Pain SCAMP effectively streamlines cardiac testing and reduces resource utilization. Further reductions can be made by algorithm refinement regarding echocardiograms for exertional symptoms. © 2017 Wiley Periodicals, Inc.

  9. Create positive contraceptive images for strongest impact in single lesson.

    Science.gov (United States)

    1987-05-01

    Health educators attempting to deliver contraceptive information to adolescents in the classroom must seek ways to make a major impact in a very short period of time. A Planned Parenthood professional from New Jersey has developed a single-shot birth control lesson that, rather than presenting the pros and cons of various contraceptive methods, has teenagers identify themselves as at high, low, or no risk of pregnancy. Students estimate the number of classmates who are in each category and then assess whether they personally are at risk of an unintended pregnancy. In general, teens overestimate the number of classmates who are sexually active. This approach seems to make the ensuing discussion of contraceptive methods more meaningful. This discussion presents the condom and foam, the sponge, and visiting a family planning clinic. After this 40 minute presentation, fewer adolescents report being afraid of contraceptive side effects; they also have more knowledge about the efficacy and availability of different methods. A lesson in preparation is centered around a videotape entitled "Swept Away is Not Okay." It shows a teen couple going to a family planning clinic before they ever have intercourse. This strategy of encouraging adolescents to seek contraception before sexual involvement begins is considered more realistic than pressuring teens to abstain from sex. School officials and teachers have been receptive to this educational approach, viewing it as presenting important public health information.

    Purpose: In our clinic, physicists spend from 15 to 60 min to verify the physical and dosimetric integrity of radiotherapy plans before presentation to radiation oncology physicians for approval. The purpose of this study was to design and implement a framework to automate as many elements of this quality control (QC) step as possible. Methods: A comprehensive computer application was developed to carry out a majority of these verification tasks in the Philips PINNACLE treatment planning system (TPS). This QC tool functions based on both PINNACLE scripting elements and PERL sub-routines. The core of this technique is the method of dynamic scripting, which involves a PERL programming module that is flexible and powerful for treatment plan data handling. Run-time plan data are collected, saved into temporary files, and analyzed against standard values and predefined logical rules. The results were summarized in a hypertext markup language (HTML) report that is displayed to the user. Results: This tool has been in clinical use for over a year. The occurrence frequency of technical problems, which would cause delays and suboptimal plans, has been reduced since clinical implementation. Conclusions: In addition to drastically reducing the set of human-driven logical comparisons, this QC tool also accomplished some tasks that are otherwise either quite laborious or impractical for humans to verify, e.g., identifying conflicts amongst IMRT optimization objectives.

    2016-01-01

    Purpose: To investigate, in a treatment plan design and robustness study, whether proton pencil beam scanning (PBS) has the potential to offer advantages, relative to interfraction uncertainties, over photon volumetric modulated arc therapy (VMAT) in a locally advanced rectal cancer patient population. Methods and Materials: Ten patients received a planning CT scan, followed by an average of 4 weekly offline CT verification CT scans, which were rigidly co-registered to the planning CT. Clinical PBS plans were generated on the planning CT, using a single-field uniform-dose technique with single-posterior and parallel-opposed (LAT) fields geometries. The VMAT plans were generated on the planning CT using 2 6-MV, 220° coplanar arcs. Clinical plans were forward-calculated on verification CTs to assess robustness relative to anatomic changes. Setup errors were assessed by forward-calculating clinical plans with a ±5-mm (left–right, anterior–posterior, superior–inferior) isocenter shift on the planning CT. Differences in clinical target volume and organ at risk dose–volume histogram (DHV) indicators between plans were tested for significance using an appropriate Wilcoxon test (P<.05). Results: Dosimetrically, PBS plans were statistically different from VMAT plans, showing greater organ at risk sparing. However, the bladder was statistically identical among LAT and VMAT plans. The clinical target volume coverage was statistically identical among all plans. The robustness test found that all DVH indicators for PBS and VMAT plans were robust, except the LAT's genitalia (V5, V35). The verification CT plans showed that all DVH indicators were robust. Conclusions: Pencil beam scanning plans were found to be as robust as VMAT plans relative to interfractional changes during treatment when posterior beam angles and appropriate range margins are used. Pencil beam scanning dosimetric gains in the bowel (V15, V20) over VMAT suggest that using PBS to treat rectal cancer

    When assessing the financial implications of a physician alignment and clinical integration initiative, a hospital should measure the initiative's potential ROI, perhaps best using a combination of net present value and payback period. The hospital should compare its own historical and projected performance with rating agency median benchmarks for key financial indicators of profitability, debt service, capital and cash flow, and liquidity. The hospital should also consider potential indirect benefits, such as retained outpatient/ancillary revenue, increased inpatient revenue, improved cost control, and improved quality and reporting transparency.

    2003-01-01

    Under various clinical situations, it is desirable to modify the original treatment plan to better suit the clinical goals. In this work, a method to help physicians modify treatment plans based on their clinical preferences is proposed. The method uses a weighted quadratic dose objective function. The commonly used organ-/ROI-based weighting factors are expanded to a set of voxel-based weighting factors in order to obtain greater flexibility in treatment plan modification. Two different but equivalent modification schemes based on Rustem's quadratic programming algorithms -modification of a weighting matrix and modification of prescribed doses - are presented. Case studies demonstrated the effectiveness of the two methods with regard to their capability to fine-tune treatment plans

    Purpose: A geometrically based method of multiple isocenter linear accelerator radiosurgery treatment planning optimization was developed, based on a target's solid shape. Methods and Materials: Our method uses an edge detection process to determine the optimal sphere packing arrangement with which to cover the planning target. The sphere packing arrangement is converted into a radiosurgery treatment plan by substituting the isocenter locations and collimator sizes for the spheres. Results: This method is demonstrated on a set of 5 irregularly shaped phantom targets, as well as a set of 10 clinical example cases ranging from simple to very complex in planning difficulty. Using a prototype implementation of the method and standard dosimetric radiosurgery treatment planning tools, feasible treatment plans were developed for each target. The treatment plans generated for the phantom targets showed excellent dose conformity and acceptable dose homogeneity within the target volume. The algorithm was able to generate a radiosurgery plan conforming to the Radiation Therapy Oncology Group (RTOG) guidelines on radiosurgery for every clinical and phantom target examined. Conclusions: This automated planning method can serve as a valuable tool to assist treatment planners in rapidly and consistently designing conformal multiple isocenter radiosurgery treatment plans.

    An atlas-based IMRT planning technique for prostate cancer was developed and evaluated. A multi-dose atlas was built based on the anatomy patterns of the patients, more specifically, the percent distance to the prostate and the concaveness angle formed by the seminal vesicles relative to the anterior-posterior axis. A 70-case dataset was classified using a k-medoids clustering analysis to recognize anatomy pattern variations in the dataset. The best classification, defined by the number of classes or medoids, was determined by the largest value of the average silhouette width. Reference plans from each class formed a multi-dose atlas. The atlas-guided planning (AGP) technique started with matching the new case anatomy pattern to one of the reference cases in the atlas; then a deformable registration between the atlas and new case anatomies transferred the dose from the atlas to the new case to guide inverse planning with full automation. 20 additional clinical cases were re-planned to evaluate the AGP technique. Dosimetric properties between AGP and clinical plans were evaluated. The classification analysis determined that the 5-case atlas would best represent anatomy patterns for the patient cohort. AGP took approximately 1 min on average (corresponding to 70 iterations of optimization) for all cases. When dosimetric parameters were compared, the differences between AGP and clinical plans were less than 3.5%, albeit some statistical significances observed: homogeneity index (p  >  0.05), conformity index (p  <  0.01), bladder gEUD (p  <  0.01), and rectum gEUD (p  =  0.02). Atlas-guided treatment planning is feasible and efficient. Atlas predicted dose can effectively guide the optimizer to achieve plan quality comparable to that of clinical plans. (paper)

    Purpose: To evaluate the effectiveness of an automated plan check tool to improve first-time plan quality as well as standardize and document performance of physics plan checks. Methods: The Plan Checker Tool (PCT) uses the Eclipse Scripting API to check and compare data from the treatment planning system (TPS) and treatment management system (TMS). PCT was created to improve first-time plan quality, reduce patient delays, increase efficiency of our electronic workflow, and to standardize and partially automate plan checks in the TPS. A framework was developed which can be configured with different reference values and types of checks. One example is the prescribed dose check where PCT flags the user when the planned dose and the prescribed dose disagree. PCT includes a comprehensive checklist of automated and manual checks that are documented when performed by the user. A PDF report is created and automatically uploaded into the TMS. Prior to and during PCT development, errors caught during plan checks and also patient delays were tracked in order to prioritize which checks should be automated. The most common and significant errors were determined. Results: Nineteen of 33 checklist items were automated with data extracted with the PCT. These include checks for prescription, reference point and machine scheduling errors which are three of the top six causes of patient delays related to physics and dosimetry. Since the clinical roll-out, no delays have been due to errors that are automatically flagged by the PCT. Development continues to automate the remaining checks. Conclusion: With PCT, 57% of the physics plan checklist has been partially or fully automated. Treatment delays have declined since release of the PCT for clinical use. By tracking delays and errors, we have been able to measure the effectiveness of automating checks and are using this information to prioritize future development.

    The study was conducted to estimate the long-term costs for implementing citizenship documentation requirements in a Medicaid expansion program for family planning services in Oregon. A decision-analytic model was developed using two perspectives: the state and society. Our primary outcome was future reproductive health care costs due to pregnancy in the next 5 years. A Markov structure was utilized to capture multiple future pregnancies. Model inputs were retrieved from the existing literature and local hospital and Medicaid data related to reimbursements. One-way and multi-way sensitivity analyses were conducted. A Monte Carlo simulation was performed to simultaneously incorporate uncertainty from all of the model inputs. Screening for citizenship results in a loss of $3119 over 5 years ($39,382 vs. $42,501) for the state and $4209 for society ($63,391 compared to $59,182) for adult women. Among adolescents, requiring proof of identity and citizenship results in a loss of $3123 for the state ($39,378 versus $42,501) and $4214 for society ($63,391 instead of $59,177). Screening for citizenship status in publicly funded family planning clinics leads to financial losses for the state and society. Copyright © 2011 Elsevier Inc. All rights reserved.

    Purpose: To develop a new IMRT treatment planning methodology suitable for the new generation of MR-linear accelerator machines. The pipeline is able to deliver Pareto-optimal plans and can be utilized for conventional treatments as well as for inter- and intrafraction plan adaptation based on real-time MR-data. Methods: A Pareto-optimal plan is generated using the automated multicriterial optimization approach Erasmus-iCycle. The resulting dose distribution is used as input to the second part of the pipeline, an iterative process which generates deliverable segments that target the latest anatomical state and gradually converges to the prescribed dose. This process continues until a certain percentage of the dose has been delivered. Under a conventional treatment, a Segment Weight Optimization (SWO) is then performed to ensure convergence to the prescribed dose. In the case of inter- and intrafraction adaptation, post-processing steps like SWO cannot be employed due to the changing anatomy. This is instead addressed by transferring the missing/excess dose to the input of the subsequent fraction. In this work, the resulting plans were delivered on a Delta4 phantom as a final Quality Assurance test. Results: A conventional static SWO IMRT plan was generated for two prostate cases. The sequencer faithfully reproduced the input dose for all volumes of interest. For the two cases the mean relative dose difference of the PTV between the ideal input and sequenced dose was 0.1% and −0.02% respectively. Both plans were delivered on a Delta4 phantom and passed the clinical Quality Assurance procedures by achieving 100% pass rate at a 3%/3mm gamma analysis. Conclusion: We have developed a new sequencing methodology capable of online plan adaptation. In this work, we extended the pipeline to support Pareto-optimal input and clinically validated that it can accurately achieve these ideal distributions, while its flexible design enables inter- and intrafraction plan

    BACKGROUND: Assessment of target dose conformity in multi-dose-level treatment plans is challenging due to inevitable over/underdosage at the border zone between dose levels. Here, we evaluate different target dose prescription planning aims and approaches to evaluate the relative merit of such p......-painting and multi-dose-level plans. The tool can be useful for quality assurance of multi-center trials, and for visualizing the development of treatment planning in routine clinical practice....... of such plans. A quality volume histogram (QVH) tool for history-based evaluation is proposed. MATERIAL AND METHODS: Twenty head and neck cancer dose-painting plans with five prescription levels were evaluated, as well as clinically delivered simultaneous integrated boost (SIB) plans from 2010 and 2012.

    Abbas, Ismail; Rovira, Joan; Casanovas, Josep

    2007-05-01

    The patient recruitment process of clinical trials is an essential element which needs to be designed properly. In this paper we describe different simulation models under continuous and discrete time assumptions for the design of recruitment in clinical trials. The results of hypothetical examples of clinical trial recruitments are presented. The recruitment time is calculated and the number of recruited patients is quantified for a given time and probability of recruitment. The expected delay and the effective recruitment durations are estimated using both continuous and discrete time modeling. The proposed type of Monte Carlo simulation Markov models will enable optimization of the recruitment process and the estimation and the calibration of its parameters to aid the proposed clinical trials. A continuous time simulation may minimize the duration of the recruitment and, consequently, the total duration of the trial.

    Purpose: We retrospectively analyzed treatment outcomes among resectable gastric cancer patients treated preoperatively with chemoradiation therapy (CRT) but rendered ineligible for planned surgery because of clinical deterioration or development of overt metastatic disease. Methods and Materials: Between 1996 and 2004, 39 patients with potentially resectable gastric cancer received preoperative CRT but failed to undergo surgery. At baseline clinical staging, 33 (85%) patients had T3-T4 disease, and 27 (69%) patients had nodal involvement. Most patients received 45 Gy of radiotherapy with concurrent 5-fluorouracil-based chemotherapy. Twenty-one patients underwent induction chemotherapy before CRT. Actuarial times to local control (LC), distant control (DC), and overall survival (OS) were calculated by the Kaplan-Meier method. Results: The cause for surgical ineligibility was development of metastatic disease (28 patients, 72%; predominantly peritoneal, 18 patients), poor performance status (5 patients, 13%), patient/physician preference (4 patients, 10%), and treatment-related death (2 patients, 5%). With a median follow-up of 8 months (range, 1-95 months), actuarial 1-year LC, DC, and OS were 46%, 12%, and 36%, respectively. Median LC and OS were 11.0 and 10.1 months, respectively. Conclusions: Patients with potentially resectable gastric cancer treated with preoperative CRT are found to be ineligible for surgery principally because of peritoneal progression. Patients who are unable to undergo planned surgery have outcomes comparable to that of patients with advanced gastric cancer treated with chemotherapy alone. CRT provides durable LC for the majority of the remaining life of these patients

    Documentation rates of patients' medical wishes are often low. It is unknown whether easy-to-use, patient-facing advance care planning (ACP) interventions can overcome barriers to planning in busy primary care settings. To compare the efficacy of an interactive, patient-centered ACP website (PREPARE) with an easy-to-read advance directive (AD) to increase planning documentation. This was a comparative effectiveness randomized clinical trial from April 2013 to July 2016 conducted at multiple primary care clinics at the San Francisco VA Medical Center. Inclusion criteria were age of a least 60 years; at least 2 chronic and/or serious conditions; and 2 or more primary care visits; and 2 or more additional clinic, hospital, or emergency room visits in the last year. Participants were randomized to review PREPARE plus an easy-to-read AD or the AD alone. There were no clinician and/or system-level interventions or education. Research staff were blinded for all follow-up measurements. The primary outcome was new ACP documentation (ie, legal forms and/or discussions) at 9 months. Secondary outcomes included patient-reported ACP engagement at 1 week, 3 months, and 6 months using validated surveys of behavior change process measures (ie, 5-point knowledge, self-efficacy, readiness scales) and action measures (eg, surrogate designation, using a 0-25 scale). We used intention-to-treat, mixed-effects logistic and linear regression, controlling for time, health literacy, race/ethnicity, baseline ACP, and clustering by physician. The mean (SD) age of 414 participants was 71 (8) years, 38 (9%) were women, 83 (20%) had limited literacy, and 179 (43%) were nonwhite. No participant characteristic differed significantly among study arms at baseline. Retention at 6 months was 90%. Advance care planning documentation 6 months after enrollment was higher in the PREPARE arm vs the AD-alone arm (adjusted 35% vs 25%; odds ratio, 1.61 [95% CI, 1.03-2.51]; P = .04). PREPARE also resulted

    Purpose: In this article, an approach to metal artifact reduction is proposed that is practical for clinical use in radiation therapy. It is based on a new interpolation scheme of the projections associated with metal implants in helical computed tomography (CT) scanners. Methods and Materials: A three-step approach was developed consisting of an automatic algorithm for metal implant detection, a correction algorithm for helical projections, and a new, efficient algorithm for projection interpolation. The modified raw projection data are transferred back to the CT scanner device where CT slices are regenerated using the built-in reconstruction operator. The algorithm was tested on a CT calibration phantom in which the density of inserted objects are known and on clinical prostate cases with two hip prostheses. The results are evaluated using the CT number and shape of the objects. Results: The validations on a CT calibration phantom with various inserts of known densities show that the algorithm improved the overall image quality by restoring the shape and the representative CT number of the objects in the image. For the clinical hip replacement cases, a large fraction of the bladder, rectum, and prostate that were not visible on the original CT slices were recovered using the algorithm. Precise contouring of the target volume was thus feasible. Without this enhancement, physicians would have drawn bigger margins to be sure to include the target and, at the same time, could have prescribed a lower dose to keep the same level of normal tissue toxicity. Conclusions: In both phantom experiment and patient studies, the algorithm resulted in significant artifact reduction with increases in the reliability of planning procedure for the case of metallic hip prostheses. This algorithm is now clinically used as a preprocessing before treatment planning for metal artifact reduction

    The multi-objective optimization of inverse planning based on the Pareto solution set, according to the multi-objective character of inverse planning in accurate radiotherapy, was studied in this paper. Firstly, the clinical requirements of a treatment plan were transformed into a multi-objective optimization problem with multiple constraints. Then, the fast and elitist multi-objective Non-dominated Sorting Genetic Algorithm (NSGA-II) was introduced to optimize the problem. A clinical example was tested using this method. The results show that an obtained set of non-dominated solutions were uniformly distributed and the corresponding dose distribution of each solution not only approached the expected dose distribution, but also met the dose-volume constraints. It was indicated that the clinical requirements were better satisfied using the method and the planner could select the optimal treatment plan from the non-dominated solution set. (authors)

    Methods of overcoming resistance to publicly subsidized family planning programs are discussed. The main sources of opposition include groups that oppose family planning for moral reasons, and those who object to the spending of government funds to provide services and information. Such opposition can be weakened by indicating that family planning clinics fulf: 11 important medical needs. Presenting social justification for family planning can help to lower oppostion. In order to secure participation in the programs by low income groups it is essential to have community leaders involved in policy decisions and to use indigenous community paraprofessionals in the clinics. A coalition of representatives of the poor community and the health and welfare system, aided by the community organization, can lead to an effective family planning program.

    The principles of treatment planning using beams of fast neutron irradiation are the same as that involved in X-ray therapy. The optimum treatment technique to be employed and the standard of dose distribution depend on the penetration of the beam, the sophistication of the treatment head and certain clinical constraints. These inter-related factors are briefly discussed. The Edinburgh Cyclotron produces d(15)+Be neutrons and compared to megavoltage X-rays it is necessary to use a greater number of fields, respect greater restraints on planning and, when wedge filters are used, accept relatively higher doses in 'hot spots'. With careful and detailed planning satisfactory dose distributions can be achieved. The procedures followed in clinical planning, field selection and dose computation are described. (orig.)

    Purpose: To investigate the dose volume histogram (DVH) prediction varieties based on intensity modulate radiotherapy (IMRT) plan or volume arc modulate radiotherapy (VMAT) plan models on the RapidPlan. Methods: Two DVH prediction models were generated in this study, including an IMRT model trained from 83 IMRT rectum plans and a VMAT model trained from 60 VMAT rectum plans. In the internal validation, 20 plans from each training database were selected to verify the clinical feasibility of the model. Then, 10 IMRT plans (PIMRT-by-IMRT-model) generated from IMRT model and 10 IMRT plans generated from VMAT model (PIMRT-by-VMAT-model) were compared on the dose to organs at risk (OAR), which included bladder, left and right femoral heads. The similar comparison was also performed on the VMAT plans generated from IMRT model (PVMAT-by-IMRT-model) and VMAT plans generated from VMAT (PVMAT-by-VMAT-model) model. Results: For the internal validation, all plans from IMRT or VMAT model shows significantly improvement on OAR sparing compared with the corresponded clinical ones. Compared to the PIMRT-by-VMAT-model, the PIMRT-by-IMRT-model has a reduction of 6.90±3.87%(p<0.001) on V40 6.63±3.62%(p<0.001) on V45 and 4.74±2.26%(p<0.001) on V50 in bladder; and a mean dose reduction of 2.12±1.75Gy(p=0.004) and 2.84±1.53Gy(p<0.001) in right and left femoral head, respectively. There was no significant difference on OAR sparing between PVMAT-by-IMRT-model and PVMAT-by-VMAT-model. Conclusion: The IMRT model for the rectal cancer in the RapidPlan can be applied to for VMAT planning. However, the VMAT model is not suggested to use in the IMRT planning. Cautions should be taken that the planning model based on some technique may not feasible to other planning techniques.

    2009-01-01

    Brachytherapy is a mature treatment modality that has benefited from technological advances. Treatment planning has advanced from simple lookup tables to complex, computer-based dose-calculation algorithms. The current approach is based on the AAPM TG-43 formalism with recent advances in acquiring single-source dose distributions. However, this formalism has clinically relevant limitations for calculating patient dose. Dose-calculation algorithms are being developed based on Monte Carlo methods, collapsed cone, and solving the linear Boltzmann transport equation. In addition to improved dose-calculation tools, planning systems and brachytherapy treatment planning will account for material heterogeneities, scatter conditions, radiobiology, and image guidance. The AAPM, ESTRO, and other professional societies are working to coordinate clinical integration of these advancements. This Vision 20/20 article provides insight into these endeavors.

    Objective: With the Monte Carlo method to recalculate the IMRT dose distributions from four TPS to provide a platform for independent comparison and evaluation of the plan quality.These results will help make a clinical decision as which TPS will be used for prostate IMRT planning. Methods: Eleven prostate cancer cases were planned with the Corvus, Xio, Pinnacle and Eclipse TPS. The plans were recalculated by Monte Carlo using leaf sequences and MUs for individual plans. Dose-volume-histograms and isodose distributions were compared. Other quantities such as D min (the minimum dose received by 99% of CTV/PTV), D max (the maximum dose received by 1% of CTV/PTV), V 110% , V 105% , V 95% (the volume of CTV/PTV receiving 110%, 105%, 95% of the prescription dose), the volume of rectum and bladder receiving >65 Gy and >40 Gy, and the volume of femur receiving >50 Gy were evaluated. Total segments and MUs were also compared. Results: The Monte Carlo results agreed with the dose distributions from the TPS to within 3%/3 mm. The Xio, Pinnacle and Eclipse plans show less target dose heterogeneity and lower V 65 and V 40 for the rectum and bladder compared to the Corvus plans. The PTV D min is about 2 Gy lower for Xio plans than others while the Corvus plans have slightly lower female head V 50 (0.03% and 0.58%) than others. The Corvus plans require significantly most segments (187.8) and MUs (1264.7) to deliver and the Pinnacle plans require fewest segments (82.4) and MUs (703.6). Conclusions: We have tested an independent Monte Carlo dose calculation system for dose reconstruction and plan evaluation. This system provides a platform for the fair comparison and evaluation of treatment plans to facilitate clinical decision making in selecting a TPS and beam delivery system for particular treatment sites.

    Computational tools are needed to make data-driven disaster mitigation planning accessible to planners and policymakers without the need for programming or GIS expertise. To address this problem, we have created modules to facilitate quantitative analyses pertinent to a variety of different disaster scenarios. These modules, which comprise the REsponse PLan ANalyzer (RE-PLAN) framework, may be used to create tools for specific disaster scenarios that allow planners to harness large amounts of disparate data and execute computational models through a point-and-click interface. Bio-E, a user-friendly tool built using this framework, was designed to develop and analyze the feasibility of ad hoc clinics for treating populations following a biological emergency event. In this article, the design and implementation of the RE-PLAN framework are described, and the functionality of the modules used in the Bio-E biological emergency mitigation tool are demonstrated.

    Eliminating family planning (FP) unmet need among HIV-infected individuals (PLHIV) is critical to elimination of mother-to-child HIV transmission. We assessed FP unmet need among PLHIV attending two clinics with differing models of FP services. Nsambya Home Care provided only FP information while Mulago HIV clinic provided information and contraceptives onsite. In a cross-sectional study conducted between February-June 2011, we documented pregnancies, fertility desires, and contraceptive use among 797 HIV-infected men and women (408 in Mulago and 389 in Nsambya). FP unmet need was calculated among women who were married, unmarried but had sex within the past month, did not desire the last or future pregnancy at all or wished to postpone for ≥ two years and were not using contraceptives. Multivariable analyses for correlates of FP unmet need were computed for each clinic. Overall, 40% (315) had been pregnant since HIV diagnosis; 58% desired the pregnancies. Of those who were not pregnant, 49% (366) did not desire more children at all; 15.7% wanted children then and 35.3% later. The unmet need for FP in Nsambya (45.1%) was significantly higher than that in Mulago at 30.9% (p = 0.008). Age 40+ compared to 18-29 years (OR = 6.05; 95% CI: 1.69, 21.62 in Mulago and OR = 0.21; 95% CI: 0.05, 0.90 in Nsambya), other Christian denominations (Pentecostal and Seventh Day Adventists) compared to Catholics (OR = 7.18; 95% CI: 2.14, 24.13 in Mulago and OR = 0.23; 95% CI: 0.06, 0.80 in Nsambya), and monthly expenditure > USD 200 compared to fertility support and elimination of FP unmet need among PLHIV, even with integration of FP information and supplies into HIV clinics.

    Purpose: To determine the implications of the use of the Anisotropic Analytical Algorithm (AAA) for the production and dosimetric verification of IMRT plans for treatments of the prostate, parotid, nasopharynx and lung. Methods: 72 IMRT treatment plans produced using the Pencil Beam Convolution (PBC) algorithm were recalculated using the AAA and the dose distributions compared. Twenty-four of the plans were delivered to inhomogeneous phantoms and verification measurements made using a pinpoint ionisation chamber. The agreement between the AAA and measurement was determined. Results: Small differences were seen in the prostate plans, with the AAA predicting slightly lower minimum PTV doses. In the parotid plans, there were small increases in the lens and contralateral parotid doses while the nasopharyngeal plans revealed a reduction in the volume of the PTV covered by the 95% isodose (the V 95% ) when the AAA was used. Large changes were seen in the lung plans, the AAA predicting reductions in the minimum PTV dose and large reductions in the V 95% . The AAA also predicted small increases in the mean dose to the normal lung and the V 20 . In the verification measurements, all AAA calculations were within 3% or 3.5 mm distance to agreement of the measured doses. Conclusions: The AAA should be used in preference to the PBC algorithm for treatments involving low density tissue but this may necessitate re-evaluation of plan acceptability criteria. Improvements to the Multi-Resolution Dose Calculation algorithm used in the inverse planning are required to reduce the convergence error in the presence of lung tissue. There was excellent agreement between the AAA and verification measurements for all sites

    Advancements in informatics in radiotherapy are opening up opportunities to improve our ability to assess treatment plans. Models on individualizing patient dose constraints from prior patient data and shape relationships have been extensively researched and are now making their way into commercial products. New developments in knowledge based treatment planning involve understanding the impact of the radiation dosimetry on the patient. Akin to radiobiology models that have driven intensity modulated radiotherapy optimization, toxicity and outcome predictions based on treatment plans and prior patient experiences may be the next step in knowledge based planning. In order to realize these predictions, it is necessary to understand how the clinical information can be captured, structured and organized with ontologies and databases designed for recall. Large databases containing radiation dosimetry and outcomes present the opportunity to evaluate treatment plans against predictions of toxicity and disease response. Such evaluations can be based on dose volume histogram or even the full 3-dimensional dose distribution and its relation to the critical anatomy. This session will provide an understanding of ontologies and standard terminologies used to capture clinical knowledge into structured databases; How data can be organized and accessed to utilize the knowledge in planning; and examples of research and clinical efforts to incorporate that clinical knowledge into planning for improved care for our patients.

    In today's challenging healthcare environment, clinicians need to understand the fundamentals of financial analysis, which are the underpinnings of their clinical programs, especially when seeking administrative support for new initiatives. The business plan for new clinical program initiatives is composed of diverse elements such as the mission statement, market and competitive analyses, operations plan, and financial analysis. Armed with a basic knowledge of financial analysis of clinical programs, as well as forward-looking analysis of an initiative's added value, the healthcare provider can work much more effectively with administration in developing or creating new healthcare program initiatives.

    The introduction of digital radiological facilities leads to the necessity of digital preoperative planning, which is an essential part of joint replacement surgery. To avoid errors in the preparation and execution of hip surgery, reliable correction of the magnification of the projected hip is a prerequisite. So far, no validated method exists to accomplish this. We present validated geometrical models of the x-ray projection of spheres, relevant for the calibration procedure to correct for the radiographic magnification. With help of these models a new calibration protocol was developed. The validity and precision of this procedure was determined in clinical practice. Magnification factors could be predicted with a maximal margin of error of 1.5%. The new calibration protocol is valid and reliable. The clinical tests revealed that correction of magnification has a 95% margin of error of -3% to +3%. Future research might clarify if a strict calibration protocol, as presented in this study, results in more accurate preoperative planning of hip joint replacements

    Purpose: Develop and clinically validate a methodology for using cone beam computed tomography (CBCT) imaging in an automated treatment planning framework for breast IMRT. Methods: A technique for intensity correction of CBCT images was developed and evaluated. The technique is based on histogram matching of CBCT image sets, using information from “similar” planning CT image sets from a database of paired CBCT and CT image sets (n = 38). Automated treatment plans were generated for a testing subset (n = 15) on the planning CT and the corrected CBCT. The plans generated on the corrected CBCT were compared to the CT-based plans in terms of beam parameters, dosimetric indices, and dose distributions. Results: The corrected CBCT images showed considerable similarity to their corresponding planning CTs (average mutual information 1.0±0.1, average sum of absolute differences 185 ± 38). The automated CBCT-based plans were clinically acceptable, as well as equivalent to the CT-based plans with average gantry angle difference of 0.99°±1.1°, target volume overlap index (Dice) of 0.89±0.04 although with slightly higher maximum target doses (4482±90 vs 4560±84, P < 0.05). Gamma index analysis (3%, 3 mm) showed that the CBCT-based plans had the same dose distribution as plans calculated with the same beams on the registered planning CTs (average gamma index 0.12±0.04, gamma <1 in 99.4%±0.3%). Conclusions: The proposed method demonstrates the potential for a clinically feasible and efficient online adaptive breast IMRT planning method based on CBCT imaging, integrating automation

    Telemedicine facilitates decentralized radiotherapy services by allowing remote treatment planning and quality assurance of treatment delivery. A prerequisite is digital storage of relevant data and an efficient and reliable telecommunication system between satellite units and the main radiotherapy clinic. The requirements of a telemedicine system in radiotherapy is influenced by the level of support needed. In this paper we differentiate between three categories of telemedicine support in radiotherapy. Level 1 features video conferencing and display of radiotherapy images and dose plans. Level 2 involves replication of selected data from the radiotherapy database - facilitating remote treatment planning and evaluation. Level 3 includes real-time, remote operations, e.g. target volume delineation and treatment planning performed by the team at the satellite unit under supervision and guidance from more experienced colleagues at the main clinic.

    The purpose of this study was to demonstrate the feasibility of physician driven planning in intensity modulated radiotherapy (IMRT) with a multicriteria optimization (MCO) treatment planning system and template based plan optimization. Exploiting the full planning potential of MCO navigation, this alternative planning approach intends to improve planning efficiency and individual plan quality. Planning was retrospectively performed on 12 brain tumor and 10 post-prostatectomy prostate patients previously treated with MCO-IMRT. For each patient, physicians were provided with a template-based generated Pareto surface of optimal plans to navigate, using the beam angles from the original clinical plans. We compared physician generated plans to clinically delivered plans (created by dosimetrists) in terms of dosimetric differences, physician preferences and planning times. Plan qualities were similar, however physician generated and clinical plans differed in the prioritization of clinical goals. Physician derived prostate plans showed significantly better sparing of the high dose rectum and bladder regions (p(D1) plans indicated higher doses for targets and brainstem (p(D1) plan comparisons physicians preferred the clinical plans more often (brain: 6:3 out of 12, prostate: 2:6 out of 10) (not statistically significant). While times of physician involvement were comparable for prostate planning, the new workflow reduced the average involved time for brain cases by 30%. Planner times were reduced for all cases. Subjective benefits, such as a better understanding of planning situations, were observed by clinicians through the insight into plan optimization and experiencing dosimetric trade-offs. We introduce physician driven planning with MCO for brain and prostate tumors as a feasible planning workflow. The proposed approach standardizes the planning process by utilizing site specific templates and integrates physicians more tightly into treatment planning. Physicians

    Purpose: To develop an online framework that tracks a patient’s plan from initial simulation to treatment and that helps automate elements of the physics plan checks usually performed in the record and verify (RV) system and treatment planning system. Methods: We have developed PlanTracker, an online plan tracking system that automatically imports new patients tasks and follows it through treatment planning, physics checks, therapy check, and chart rounds. A survey was designed to collect information about the amount of time spent by medical physicists in non-physics related tasks. We then assessed these non-physics tasks for automation. Using these surveys, we directed our PlanTracker software development towards the automation of intra-plan physics review. We then conducted a systematic evaluation of PlanTracker’s accuracy by generating test plans in the RV system software designed to mimic real plans, in order to test its efficacy in catching errors both real and theoretical. Results: PlanTracker has proven to be an effective improvement to the clinical workflow in a radiotherapy clinic. We present data indicating that roughly 1/3 of the physics plan check can be automated, and the workflow optimized, and show the functionality of PlanTracker. When the full system is in clinical use we will present data on improvement of time use in comparison to survey data prior to PlanTracker implementation. Conclusion: We have developed a framework for plan tracking and automatic checks in radiation therapy. We anticipate using PlanTracker as a basis for further development in clinical/research software. We hope that by eliminating the most simple and time consuming checks, medical physicists may be able to spend their time on plan quality and other physics tasks rather than in arithmetic and logic checks. We see this development as part of a broader initiative to advance the clinical/research informatics infrastructure surrounding the radiotherapy clinic. This research

    Introduction Unintended pregnancy has been a concerning public health problem for decades. As we begin to understand the complexities of pregnancy intention and how women experience these pregnancies, reproductive life planning offers a paradigm shift. Methods Reproductive life planning is a patient-centered approach that places a patient's reproductive preferences-whether concrete or ambivalent-at the forefront of her clinical care. Results This process grants women and men the opportunity to consider how reproduction fits within the context of their broader lives. Within a clinical encounter, reproductive life planning allows counseling and care to be tailored to patient preferences. Discussion Although there is great potential for positive public health impacts in unintended pregnancy, contraceptive use and improved preconception health, the true benefit lies within reinforcing reproductive empowerment. Despite recommendations for universal adoption, many questions remain regarding implementation, equity and outcomes.

    Numerous studies of early-stage breast cancer treated with breast conserving surgery (BCS) and radiotherapy (RT) have been published in recent years. Both external beam radiotherapy (EBRT) and/or brachytherapy (BT) with different fractionation schemes are currently used. The present RT practice is largely based on empirical experience and it lacks a reliable modelling tool to compare different RT modalities or to design new treatment strategies. The purpose of this work is to derive a plausible set of radiobiological parameters that can be used for RT treatment planning. The derivation is based on existing clinical data and is consistent with the analysis of a large number of published clinical studies on early-stage breast cancer. A large number of published clinical studies on the treatment of early breast cancer with BCS plus RT (including whole breast EBRT with or without a boost to the tumour bed, whole breast EBRT alone, brachytherapy alone) and RT alone are compiled and analysed. The linear quadratic (LQ) model is used in the analysis. Three of these clinical studies are selected to derive a plausible set of LQ parameters. The potential doubling time is set a priori in the derivation according to in vitro measurements from the literature. The impact of considering lower or higher T pot is investigated. The effects of inhomogeneous dose distributions are considered using clinically representative dose volume histograms. The derived LQ parameters are used to compare a large number of clinical studies using different regimes (e.g., RT modality and/or different fractionation schemes with different prescribed dose) in order to validate their applicability. The values of the equivalent uniform dose (EUD) and biologically effective dose (BED) are used as a common metric to compare the biological effectiveness of each treatment regime. We have obtained a plausible set of radiobiological parameters for breast cancer. This set of parameters is consistent with in vitro

    Radiation treatments in radiation oncology clinics have been always planned to irradiate three dimensional (3D) volumes. Though the term 3D planning has come in vogue only in recent years, the essence of 3D planning had been always there. This is because the patient is a 3D subject and every treatment option adopted in a radiotherapy clinic has to be based on a 3D judgement of its acceptability. An essential aspect of training of radiation oncology residents is to help them understand the different techniques and methods used to get an acceptable 3D dose delivery. The tools of 3D planning should be introduced to the residents for their educational value. The regular use of these tools may require not only fast computers and work stations, but also a change of routine in the department. This might be difficult since the departmental routine can evolve only gradually. On the other hand, an insight about the advantages of the tools could be gained through a simple personal computer. Some examples of using the 3D planning tools through a personal computer, for educational purposes have been presented here, using clinical contexts routinely encountered. (author). 5 refs., 10 figs

    Purpose: To evaluate the directional dependency of 2D seven 29 ion chamber array clinically with different IMRT plans. Methods: 25 patients already treated with IMRT plans were selected for the study. Verification plans were created for each treatment plan in eclipse 10 treatment planning system using the AAA algorithm with the 2D array and the Octavius CT phantom. Verification plans were done 2 times for a single patient. First plan with real IMRT (plan-related approach) and second plan with zero degree gantry angle (field-related approach). Measurements were performed on a Varian Clinac-iX, linear accelerator equipped with a millennium 120 multileaf collimator. Fluence was measured for all the delivered plans and analyzed using the verisoft software. Comparison was done by selecting the fluence delivered in static gantry (zero degree gantry) versus IMRT with real gantry angles. Results: The gamma pass percentage is greater than 97 % for all IMRT delivered with zero gantry angle and between 95%–98% for real gantry angles. Dose difference between the TPS calculated and measured for IMRT delivered with zero gantry angle was found to be between (0.03 to 0.06Gy) and with real gantry angles between (0.02 to 0.05Gy). There is a significant difference between the gamma analysis between the zero degree and true angle with a significance of 0.002. Standard deviation of gamma pass percentage between the IMRT plans with zero gantry angle was 0.68 and for IMRT with true gantry angle was found to be 0.74. Conclusion: The gamma analysis for IMRT with zero degree gantry angles shows higher pass percentage than IMRT delivered with true gantry angles. Verification plans delivered with true gantry angles lower the verification accuracy when 2D array is used for measurement.

    The nation continues its ceaseless struggle with the spiraling cost of health care. Previous efforts (regulation, competition, voluntary action) have included almost every strategy except clinical. Insurers have largely failed in their cost-containment efforts. There is a strong emerging body of literature that demonstrates the relationship between various clinical strategies and reductions in utilization and costs. This article describes the organization of health services, including integration of delivery and financing systems, at the community level as a model that effectively addresses the critical structural flaws that have frustrated control of costs. Community-based health plans (CHPs) have been developed and have demonstrated viability. The key elements of CHPs are a legal organizational structure, a full provider network, advanced care-management systems, and the ability to assume financial risk. Common misconceptions regarding obstacles to CHP development are the complexity of the undertaking, difficulty assuming the insurance function, and insured pools that are too small to be viable. The characteristics of successful CHPs and 2 case studies are described, including the types of advanced care-management systems that have resulted in strong financial performance. The demonstrated ability of CHPs to establish financial viability with small numbers of enrollees challenges the common assumption that there is a fixed relationship between health plan enrollment size and financial performance. Organizing the health system at the community/regional level provides an attractive alternative model in the health-reform debate. There is an opportunity for clinical systems and state and federal leaders to support the development of community-based integrated delivery and financing system models that, among other advantages, have significant potential to modulate the pernicious cost spiral.

    Purpose: This article presents a new optimization method for stereotactic radiosurgery treatment planning for gamma unit treatment system. Methods and Materials: The gamma unit has been utilized in stereotactic radiosurgery for about 30 years, but the usual procedure for a physician-physicist team to design a treatment plan is a trial-and-error approach. Isodose curves are viewed on two-dimensional computed tomography (CT) or magnetic resonance (MR) image planes, which is not only time consuming but also seldom achieves the optimal treatment plan, especially when the isocenter weights are regarded. We developed a treatment-planning system on a computer workstation in which Powell's optimization method is realized. The optimization process starts with the initial parameters (the number of iso centers as well as corresponding 3D iso centers' coordinates, collimator sizes, and weight factors) roughly determined by the physician-physicist team. The objective function can be changed to consider protection of sensitive tissues. Results: We use the plan parameters given by a well-trained physician-physicist team, or ones that the author give roughly as the initial parameters for the optimization procedure. Dosimetric results of optimization show a better high dose-volume conformation to the target volume compared to the doctor's plan. Conclusion: This method converges quickly and is not sensitive to the initial parameters. It achieves an excellent conformation of the estimated isodose curves with the contours of the target volume. If the initial parameters are varied, there will be a little difference in parameters' configuration, but the dosimetric results proved almost to be the same

    To look at patients' views about the way in which they are recruited to assist with postgraduate medical training (i.e. Who is the best person to ask patients to participate? When is the best time for patients to be asked?) and to compare these with clinical practice. Questionnaire surveys of 103 female family planning clinic (FPC) patients and 40 Diploma of the Faculty of Family Planning (DFFP) instructing doctors. Patients were recruited from the waiting room of a community FPC, and DFFP instructing doctors from the North West of England were recruited at an updating meeting. Patients preferred to be recruited by non-medical staff (i.e. receptionist and nurses). Few patients wanted to be asked by the training doctor. Only 9% would find it difficult to refuse a receptionist, 47% would find it difficult to refuse the instructing doctor and 65% would find it difficult to refuse the training doctor. In practice, the commonest person to recruit patients is the instructing doctor. Patients wanted to be given some time to consider the request; this was not always given. Patients may feel coerced into seeing training doctors because they find it difficult to refuse requests, particularly when they are being recruited by doctors. Non-medical staff may be more appropriate for the initial recruitment of patients. Patients need time to consider their involvement. The provision of written information may be useful. Further research is indicated to empower patients' decision-making and reduce the likelihood of coercion.

    The principles are discussed of the planning of irradiation, ie., the use of the various methods of location of a pathological focus and the possibility of semiautomatic transmission of the obtained data on a two-dimensional or spatial model. An efficient equipment is proposed for large irradiation centres which should cooperate with smaller irradiation departments for which also a range of apparatus is proposed. Irradiation planning currently applied at the Research Institute of Clinical and Experimental Oncology in Brno is described. In conclusion, some of the construction principles of semi-automatic operation of radiotherapy departments are discussed.
