  1. [The new policies of natural birth control].

    1986-01-01

    International agency donors have in recent years become increasingly interested in natural family planning (NFP). The US Agency for International Development (USAID) has made an increasing amount of funds available annually for NFP, and at 1 point, in the case of NFP, relaxed the requirement that donor agencies offer more than 1 contraceptive method, despite the argument that developing country populations do not benefit from enough information for informed consent to be guaranteeable by 1-method agency. NFP has evolved from simple counting of days to observation of changes in cervical mucus and body temperature. The self-observation and learning generally required contribute to difficulties experienced in recruitment and retention of acceptors. At a 1986 meeting in Ottawa, Canada, sponsored by the International Federation for Family Life Promotion, it was revealed that calendar (but not the more effective sympto-thermal) method of NFP is fairly common in some developing countries (it is used by 41% of Peruvian and 24% of Filipino and Sri Lankan women), and even in developed countries. The hypothesized connection between the phenomenon of "old gametes" and birth defects, feared to be a side effect of NFP, was touched on, as was the possibility of using NFP to control the sex of the fetus. It was stressed that the effect of breastfeeding on fecundability constituted NFP in many countries. Other speakers cited religious and moral reasons for promotion of NFP, adding that NFP aids marital communication. It is possible increased popularity of NFP could depend in the near future on medical and legal problems associated with artificial methods as well as the US political situation.

  2. A lost chance? Birth control policies in the Mao's China (1949-1976

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available This article analyzes the birth control policies in China during the Maoist era (1949- 1976. Considering Chinese and foreign sources, it is explained how the different campaigns of family planning took place and how these campaigns were subjected positively and negatively to the policies of the supreme leader Mao Zedong. Although only the last one had a real impact on the fight against overpopulation, all campaigns helped to promote the necessity of confronting this phenomenon. More importantly, they laid the foundations of the birth control policies that currently take place in China.

  14. Infant's sex, birth control policy and postpartum well-being: a prospective cohort study in Shanghai, China.

    Hua, Jing; Zhu, Liping; Du, Wenchong; Du, Li; Luo, Ting; Wu, Zhuochun

    2016-10-06

    The majority of Chinese families were under either one-child or two-child birth control policy status from 2001 to 2015. We explore the association between an infant's sex and the mother's postpartum well-being, which may be moderated by birth control policy status in China. We conducted a prospective cohort study in Shanghai City, one of the largest cities in China. A total number of 1730 childbearing women from eight obstetric hospitals across Shanghai were included in the study at baseline, with 1503 women completing the survey 7 days postpartum in 2013. The General Well-Being Schedule (GWBS) was used to assess maternal well-being at baseline and follow-up investigation in the study. The women's demographic, clinical characteristics, and well-being were measured at baseline. Maternal satisfaction and postpartum well-being were assessed in the follow-up survey. Multivariable linear regression analyses showed that women who gave birth to male infants were positively associated with the total score of maternal well-being, when the participating hospitals, maternal well-being at baseline, sociodemographic characteristics, and maternal and infant health outcomes were added to the adjustments (β=1.462, pchild policy status was added to the adjustments (p>0.05). The results of a multiple logistic regression model showed that having a male infant was a risk factor of 'severe distress' (OR=1.607, pchild policy status (p>0.05). Our results emphasise the importance of conducting interventions to increase maternal general well-being, especially for those with a female infant in a society such as China where preference is for a son, and enhance the necessity of sustainability of a newly relaxed two-child policy which allows more couples to have a second child in China.

  19. The New Rich and Their Unplanned Births: Stratified Reproduction under China's Birth-planning Policy.

    Science.gov (United States)

    Shi, Lihong

    2017-12-01

    This article explores the creation and ramifications of a stratified reproductive system under China's state control of reproduction. Within this system, an emerging group of "new rich" are able to circumvent birth regulations and have unplanned births because of their financial capabilities and social networks. While China's birth-planning policy is meant to be enforced equally for all couples, the unequal access to wealth and bureaucratic power as a result of China's widening social polarization has created disparate reproductive rights and experiences. This article identifies three ways in which reproductive privileges are created. It further explores how a stratified reproductive system under state population control reinforces social polarization. While many socially marginalized couples are unable to register their unplanned children for citizenship status and social benefits, the new rich are able to legitimate their births and transfer their privilege and status to their children, thus reproducing a new generation of elites. © 2016 by the American Anthropological Association.

  1. Population control I: Birth of an ideology.

    Science.gov (United States)

    Hartmann, B

    1997-01-01

    Population control, as a major international development strategy, is a relatively recent phenomenon. However, its origins reach back to social currents in the 19th and early 20th centuries, culminating in an organized birth control movement in Europe and the United States. The conflicts and contradictions in that movement's history presage many of today's debates over population policy and women's rights. Eugenics had a deep influence on the U.S. birth control movement in the first half of the 20th century. After World War II private agencies and foundations played an important role in legitimizing population control as a way to secure Western control over Third World resources and stem political instability. In the late 1960s the U.S. government became a major funder of population control programs overseas and built multilateral support through establishment of the U.N. Fund for Population Activities. At the 1974 World Population Conference, Third World governments challenged the primacy of population control. While their critique led population agencies to change their strategies, population control remained a central component of international development and national security policies in the United States.

    2015-01-01

    The Health and Environmental Sciences Institute (HESI) Developmental and Reproductive Toxicology Technical Committee sponsored a pharmaceutical industry survey on current industry practices for contraception use during clinical trials. The objectives of the survey were to improve our understanding of the current industry practices for contraception requirements in clinical trials, the governance processes set up to promote consistency and/or compliance with contraception requirements, and the effectiveness of current contraception practices in preventing pregnancies during clinical trials. Opportunities for improvements in current practices were also considered. The survey results from 12 pharmaceutical companies identified significant variability among companies with regard to contraception practices and governance during clinical trials. This variability was due primarily to differences in definitions, areas of scientific uncertainty or misunderstanding, and differences in company approaches to enrollment in clinical trials. The survey also revealed that few companies collected data in a manner that would allow a retrospective understanding of the reasons for failure of birth control during clinical trials. In this article, suggestions are made for topics where regulatory guidance or scientific publications could facilitate best practice. These include provisions for a pragmatic definition of women of childbearing potential, guidance on how animal data can influence the requirements for male and female birth control, evidence-based guidance on birth control and pregnancy testing regimes suitable for low- and high-risk situations, plus practical methods to ascertain the risk of drug-drug interactions with hormonal contraceptives.

  4. Micro-blogs, online forums, and the birth-control policy: social media and the politics of reproduction in China.

    Science.gov (United States)

    Shi, Lihong

    2014-03-01

    In June 2012, the news of a Chinese woman's forced late-term abortion quickly spread across the internet in China. Graphic photos of the woman with the aborted fetus provoked public outrage and widespread condemnation on social media sites. In the aftermath, local authorities apologized, seven officials were given demerits, and the couple received monetary compensation. This case was put under the spotlight mainly because of the exposure of the story by family members of the woman through social media and the resulting public outcry in cyberspace. Following the disclosure of this story and public reactions online, this article explores the complex interplays among different layers of state power, the individual, and the public in reproductive politics, and discusses the ways in which social media has been utilized to resist state control of reproduction. By delving into the nuanced interactions among layers of state authorities, this article sheds light on the study of state-society relations in reproductive politics. It also calls attention to the role that social media plays in reproductive issues.

  8. Social policy and out-of-wedlock births to adolescents.

    Science.gov (United States)

    Ozawa, M N

    1990-01-01

    Data on births to single adolescents in all 50 US states were analyzed to examine whether Aid to Families with Dependent Children (AFDC) policies are linked to out of wedlock birth rates and whether poverty and unemployment in a state affect these rates. Overall neither AFDC payment level (p.05) nor its acceptance rate encourage single teenagers to bear children. States with AFDC for families with unemployed fathers (AFDC-U) (p.01) and those that enforce child support payments (p.001) exhibit lower out of wedlock birth rates among all teenagers. The higher the poverty rate in the state, the greater the out of wedlock birth rate (p.001). Yet unemployment rate has no effect on these births. State payment for abortion tends not to foster out of wedlock births among all teenagers. The direction of the results for white single teenagers basically matches those of all teenagers, except for state payment for abortion. The magnitude of the beta weight for most of the variables are much smaller, however. Statistically significant variables among whites are AFDC payment level (p.05), child support enforcement (p.05), and the poverty rate (p.05). State payment for abortion, AFDC-U, child support enforcement, unemployment, and poverty have the opposite effect on out of wedlock births among black teenagers than it does among whites. Yet the intensity is weaker than it was for whites. State payment for abortion is the only variable that is statistically significant (p.05). It tends not to encourage out of wedlock births among blacks. The proportion of the black population in the state has limited or no influence on out of wedlock birth rates for black teenagers, but it is inversely associated with out of wedlock birth rates for white teenagers (p.001). These results refute the conventional belief that AFDC promotes high birth rates among single teenagers.

    To review and summarize tobacco control policies, their impact in curbing the tobacco epidemic, and to describe a role for nursing advocacy. Published articles and research studies. Comprehensive tobacco control policy is one of the most effective mechanisms to prevent tobacco-related cancers and other illnesses. The World Health Organization's Framework Convention on Tobacco Control, and the Master Settlement Agreement in the United States have provided new opportunities for tobacco control. Nursing participation in the policy process can expand and strengthen these policies' activities. Involvement in tobacco control should be integral to oncology nursing efforts to prevent cancer, promote health, and quality of life.

  14. UNICEF supports birth control despite Holy See.

    Deen, T

    1992-01-01

    The Vatican has failed in its attempt to prevent the UN Children's Fund (UNICEF) from spreading the message of family planning in developing countries. Over the strong objections of the Holy See, the 41-member Executive Board of UNICEF has asked the agency to cooperate with the UN Population Fund (UNFPA) and the WHO "to support family planning in the context of sustainable national healthcare systems." A member of the Executive Board said the Vatican held the view that UNICEF had no legitimate right to be involved in family planning. "But the Holy See was in a minority of one," he said, adding that "the whole problem arises from the fact that the Vatican continues to equate birth control and abortion with family planning." A recently concluded board meeting unanimously adopted a resolution requesting UNICEF to "contribute substantively" to the UNFPA-sponsored International Conference on Population and Development (CPF) set to take place in 1994 in Cairo. The board also asked UNICEF Executive Director James Grant to submit a policy paper "on the involvement of UNICEF in family planning, taking into account the health of the child and the mother." The paper is to be presented for the consideration of the board at its regular session next year, with a view to approving it prior to the ICPD. Prior to the adoption of the resolution, J. Klink, a spokesman for the Holy See, told the Executive Board that there were "concerns" over calls for UNICEF to involve itself in family planning activities. He said UNICEF should not be concerned with family planning because there were other agencies entrusted with that mandate. Responding to the support given by Nordic countries to the UNICEF resolution, Klink said that wealthy nations must not impose dictates as to the "appropriate" size of poor families. "The Holy See would not propose that UNICEF halt its current balanced, informational approach to the spacing of births," he said. "Families must be free to decide their size

    Half of unmarried births are to women who are already mothers, and a quarter to women who were previously married. We develop a model of equilibrium matching and fertility to replicate these facts. We use the model to revisit the hypothesis that liberalization of the Pill and abortion caused...... the massive increase since 1960 in the share of US births to unmarried women. Our results suggest that liberalization alone is ineffective; what matters are interactions between liberalization and the decline in the stability of marriage, and, secondarily, the rising status of single mothers....

    Research in underdeveloped countries to sell family planning is discussed. The article also aims at pinpointing other possible research areas. Census reports were actually the earliest work relevant to birth control. Later came the research on psychosocial factors affecting family size in developed countries. After World War I, client oriented research into family planning began. The history of this type of research is discussed with more emphasis on the surveys of the knowledge, attitude and contraception practices (KAP) in various countries. The author claims the KAP surveys to be the largest worldwide market research job ever done. Propagands campaigns, contraceptive costs, bonuses for contraceptive practices, and effectiveness of persuasion techniques are discussed.

    Dawrant, A G

    1977-06-18

    The following item appeared recently in our local newspaper: "The Federal Government plans to press the provinces to establish special abortion clinics that would also provide family planning services, Health Minister Marc Lalonde announced. The proposed clinics would combine abortion services with family planning and birth control counseling, cancer screening and other services related to the health of mothers, he said." It seems that the federal government is attempting to cover the bitter pill of a therapeutic abortion clinic with the sugar coating of family planning and contraceptive counseling. Family planning and contraceptive counseling is an important part of the day-to-day work of the great majority of family physicians and gynecologists, and I urge all physicians who are opposed to Mr. Lalonde's proposal to contact their Members of Parliament and their representatives in the provincial legislatures. Let us urge the Canadian Medical Association to make it clear that the appropriate setting for contraceptive counseling and related services should be the office of the family physician or gynecologist. The time has come for the association to take a more aggressive approach in the field of family planning and birth control counseling and, at the same time, actively discourage government involvement in this important area of preventive medicine. Further, let us make it clear that the whole question of therapeutic abortions and abortion clinics is to be regarded as distinct from family planning and contraceptive counseling.

  1. The birth control movement before Roe v. Wade.

    Science.gov (United States)

    Reed, J W

    1995-01-01

    This essay synthesizes the history of the birth control movement in the US and describes changes in sexual behavior, social values, and public policy in order to provide a context for the changes in human reproductive public policy. After an introduction, the essay outlines the history of contraception from the early nineteenth to the early twentieth centuries. Part 3 covers the period of World War I to the Depression when civil libertarians and eugenicists began to question the suppression of contraception and Margaret Sanger organized her clinics. The fourth part of the essay carries the history forward to the end of World War II, a period in which Dr. Clarence J. Gamble began to expose the marketing of defective contraceptive methods and to illustrate the willingness of poor women to accept contraceptives. The social changes which began in the 1950s are the subject of the fifth section of the essay. During this period, Roman Catholic opposition to contraception lessened, and social scientists began to focus world attention on overpopulation. Frank Notestein was appointed the first head of the Office of Population Research at Princeton, and John D. Rockefeller III founded the Population Council which conducted research into the IUD and began to attempt to influence population growth in nonindustrialized countries. This period also saw the development of the oral contraceptive. The changes of this era were institutionalized in 1967 when the federal government took a positive stance towards family planning in its Social Security Amendments. The decade of the 1970s is the subject of the last part of this essay. This period saw the Supreme Court assign a constitutionally protected right to abortion and Congress pass the Helms Amendment which denied the use of foreign aid funds for abortions. Challenges to the right to individual birth control practice continued during this period, and debate centered around the specter of overpopulation, the threat of adolescent

  3. Immigration policy and birth weight: Positive externalities in Italian law.

    Salmasi, Luca; Pieroni, Luca

    2015-09-01

    A decade ago, the political party of the Italian center-right voted a law restricting immigration. The law became effective in early 2005, when the Italian parliament approved the decree for its application, but one of its articles, granting amnesty for illegal immigrant workers, became immediately effective in July 2002. As a result, 650,000 immigrants were granted the status of foreign nationals in Italy. In this paper, we examine whether the increase in the prevalence of "regular immigrants" has led to an improvement in health outcomes of babies born to migrant women, measured in terms of birth weight. Two hitherto unexploited birth sample surveys published by Italian Institute of Statistics were used for this study. Our estimates show that regularized immigration reduced the probability of low birth weight. Copyright © 2015 Elsevier B.V. All rights reserved.

  4. [Family planning programs and birth control in the third world].

    Science.gov (United States)

    Wohlschlagl, H

    1991-01-01

    The population explosion has been abating since the 2nd half of the 1960s. The birth rate of the 3rd World dropped from 45/1000 during 1950-55 to 31/1000 during 1985-90. From the 1st half of the 1960s to the 1st half of the 1980s the total fertility of such countries dropped from 6.1 to 4.2 children/woman. In Taiwan, Singapore, Hong Kong, South Korea, and Malaysia living standards improved as a result of industrialization, and fertility decreased significantly. In Sri Lanka, China, North Vietnam, and Thailand the drop of fertility is explained by cultural and religious factors. In 1982 about 78% of the population of developing countries lived in 39 states that followed an official policy aimed at reducing the population. Another 16% lived in countries supporting the concept of a desired family size. However, World Bank data showed that in the mid-1980s in 27 developing countries no state family planning (FP) programs existed. India adopted an official FP program in 1952, Pakistan followed suit in 1960, South Korea in 1961, and China in 1962. In Latin America a split policy manifested itself: in Brazil birth control was rejected, only Colombia had a FP policy. In 1986 the governments of 68 of 131 developing countries representing 3.1 billion people considered the number of children per woman too high. 31 of these countries followed concrete population control policies. On the other hand, in 1986 24 countries of Africa with 40% of the continent's population took no measures to influence population growth. In Latin America and the Caribbean 18 of 33 countries were idle, except for Mexico that had a massive state FP program. These programs also improve maternal and child health with birth spacing of at least 2 years, and the prevention of pregnancies of too young women or those over 40. The evaluation of rapidly spreading FP programs in the 1970s was carried out by the World Fertility Survey in 41 countries. The impact of FP programs was more substantial than

  7. Nuclear power hazard control policy

    International Nuclear Information System (INIS)

    Chicken, J.C.

    1982-01-01

    This study presents an analysis of the factors that appear to have influenced the formation and form of nuclear power hazard control policy in Britain. A simple account is given of the technical nature of nuclear hazards and of the legal and administrative framework that has been constructed to control them. The subsequent analysis concentrates primarily on the influence exerted by social and political factors. Particular attention is directed to those political groups which have developed a special interest in the problems of nuclear power, and to the interplay between organised groupings and public opinion generally. The metamorphosis of these groupings is traced from the origins of the nuclear industry in the Second World War to their prominent role during the Windscale Inquiry. Attention is given to the policy constraint imposed by increased expectations in the form of demands for higher standards of living, and improvements in the quality of the environment. The study is concerned with both policy-making and with policy implementation; with interest articulation as well as with the functioning of formal institutions. The evolution of policy takes place in an atmosphere of keen economic debate and conflicting moral perceptions. A model of the policy-making system is postulated. (author)

    Urquia, Marcelo L.

    2015-01-01

    Background We delved into the selective migration hypothesis on health by comparing birth outcomes of Latin American immigrants giving birth in two receiving countries with dissimilar immigration admission policies: Canada and Spain. We hypothesized that a stronger immigrant selection in Canada will reflect more favourable outcomes among Latin Americans giving birth in Canada than among their counterparts giving birth in Spain. Materials and Methods We conducted a cross-sectional bi-national comparative study. We analyzed birth data of singleton infants born in Canada (2000–2005) (N = 31,767) and Spain (1998–2007) (N = 150,405) to mothers born in Spanish-speaking Latin American countries. We compared mean birthweight at 37–41 weeks gestation, and low birthweight and preterm birth rates between Latin American immigrants to Canada vs. Spain. Regression analysis for aggregate data was used to obtain Odds Ratios and Mean birthweight differences adjusted for infant sex, maternal age, parity, marital status, and father born in same source country. Results Latin American women in Canada had heavier newborns than their same-country counterparts giving birth in Spain, overall [adjusted mean birthweight difference: 101 grams; 95% confidence interval (CI): 98, 104], and within each maternal country of origin. Latin American women in Canada had fewer low birthweight and preterm infants than those giving birth in Spain [adjusted Odds Ratio: 0.88; 95% CI: 0.82, 0.94 for low birthweight, and 0.88; 95% CI: 0.84, 0.93 for preterm birth, respectively]. Conclusion Latin American immigrant women had better birth outcomes in Canada than in Spain, suggesting a more selective migration in Canada than in Spain. PMID:26308857

  14. Parliament and birth control in the 1920s.

    Simms, M

    1978-02-01

    The history of the family planning movement in England in the 1920s is traced. The movement actually began with the establishment by Andrew Carnegie of maternity and child welfare clinics on an experimental basis. The government extended such clinics by legislation. The radical element within the birth control movement recognized these clinics as the perfect environment for dissemination of birth control information and supplies. In 1926 Ernest Thurtle moved in Parliament that local authorities be given authorization to provide birth control methods to married women through the clinics. His bill was permissive, allowing but not compelling the clinics to participate in family planning. He aimed at removing 1 of the disabilities of poverty and at equalizing the sexes. The issue was controversial within Parliament. Finally, the Ministry of Health issued a directive allowing birth control information and supplies to be disseminated through the clinics, thus taking the issue out of the political and legislative realm. By the early 1930s, voluntary clinics, the forerunners of today's Family Planning Association affiliates, were being set up to implement the Ministry of Health directive.

    2017-12-01

    Full Text Available This research is mainly concerned about the methods set by the Quran for preserving the human breeding, which is regarded the main pillar not only for the future survival of the humankind, but also for assuring its permanence and continuity. Taking this into consideration, the Quran has addressed this issue by setting solid preventive tools that ensure the continuity and prosperity of the human offspring in a normal manner. The objective of the research is to shed light on the importance of protecting the human offspring in the Quran, since neglecting its importance could lead to the corruption of the whole society and its members. The research attempts also to tackle the various preventive tools that the Quran has adopted for protecting the normal continuity and prosperity of the human offspring. The research proposes to study the Quranic verses that address the protection of the human offspring and the various preventive tools that should be adopted, along with the accredited analysis and statements of purpose of the Quranic verses, with reference to the approved sources of interpretation. Apart of the findings are that the Quran has set two main methods for protecting the human offspring that is; the preventive tools for protecting the amount of birth control, and the preventive tools for maintaining the quality of birth control. The preventive tools for protecting the amount of birth control include the forbidding of being monastic, the prohibiting of killing children for fear of poverty, and the forbidding of falling into immorality, either outwardly or inwardly. They also include the establishment of prayer, giving charity, reciting Dhikr (remembrance and asking of forgiveness. The preventive tools for maintaining the quality of birth control, however, include not approaching adultery, prohibiting adoption, and forbidding incest, the people of shirk and immorality and blasphemy.

    Full Text Available Low birth weight (LBW (defined as a birth weight of less than 2500 grams is associated with fetal and neonatal morbidity and mortality, impaired cognitive development, and the advent of chronic diseases in later life. The global incidence of LBW is around 15,5%. The aim of this study was to identify risk factors for low birthweight in the centre of Denizli province. A case-control study was carried out and mothers of 295 newborns with birthweight between 1500-2499 g (cases and 302 newborns with birthweight between 2500-4000 g (controls were analyzed. The questionnare was applied to women using face to face technics between July,2009 and June,2010 . The questionnare included birth weight and birth lenght of newborn, the date of last pregnacy and type of last delivery, profile of mother, anthropometric measures, life styles, habits, addictions, sociodemographic and socioeconomic characteristics of mother and father of newborn. Analysis included frequency and percent distributions, means, standart deviations. In group comparisions for categorical variable, chi square test and odds ratio (OR was used. Logistic regression model was performed for some selected risk factors. P<0.05 was considered statistically significant.

    2015-10-01

    The United States has one of the highest teen birth rates among developed countries. Interstate birth rates and abortion rates vary widely, as do policies on abortion and sex education. The objective of our study is to assess whether US state-level policies regarding abortion and sexual education are associated with different teen birth and teen abortion rates. We carried out a state-level (N = 51 [50 states plus the District of Columbia]) retrospective observational cross-sectional study, using data imported from the National Vital Statistics System. State policies were obtained from the Guttmacher Institute. We used descriptive statistics and regression analysis to study the association of different state policies with teen birth and teen abortion rates. The state-level mean birth rates, when stratifying between policies protective and nonprotective of teen births, were not statistically different-for sex education policies, 39.8 of 1000 vs 45.1 of 1000 (P = .2187); for mandatory parents' consent to abortion 45 of 1000, vs 38 of 1000 when the minor could consent (P = .0721); and for deterrents to abortion, 45.4 of 1000 vs 37.4 of 1000 (P = .0448). Political affiliation (35.1 of 1000 vs 49.6 of 1000, P teen births. Lower teen abortion rates were, however, associated with restrictive abortion policies, specifically lower in states with financial barriers, deterrents to abortion, and requirement for parental consent. While teen birth rates do not appear to be influenced by state-level sex education policies, state-level policies that restrict abortion appear to be associated with lower state teen abortion rates.

    2011-01-01

    This article employs novel documentation to examine ways in which the Church's moral rules on contraception were (or were not) communicated to parishioners in a predominantly Catholic context in a period of rapid fertility decline: the diocese of Padua, in the northeastern Italian region of Veneto, during the first half of the twentieth century. The account is based on documents that have until now been overlooked: the moral cases discussed during the periodic meetings among Padua priests in the years 1916–58, and the written answers provided by priests in response to a question asked of them concerning their efforts to combat the limiting of births. This documentation reveals the limited effect on the reproductive behavior of the position of the Catholic Church against birth control.

    This paper comments on the provision of birthing services in Sichuan and Shanxi Provinces in China within a policy context. The goal was to understand possible unintended and harmful health outcomes for women in the light of international evidence, to better inform practice and policy development. Data were collected from October 2005 to April 2007 in 25 hospitals across 13 counties and one city. Normal and caesarean birth records were audited, observations made of facilities and interviews conducted with officials, administrators, health workers, women who delivered in hospital facilities and women who delivered at home. We argue that in the context of a neo-liberal health economy with poorly developed government regulatory policies, those with the power to pay for maternity care may be vulnerable to a new range of risks to their health from those positioned to make a profit. While poor communities may lack access to basic services, wealthier socio-economic groups may risk an increase in maternal morbidity and mortality through the overuse of avoidable intervention. We recommend a stronger evidence base for hospital maternity services and changes to the role of the State in countering systemic problems.

  6. Emergency contraception – a neglected option for birth control

    Full Text Available Emergency contraception (EC is any method of contraception which is used after intercourse and before the potential time of implantation, in order to prevent pregnancy after an unprotected or inadequately protected sexual intercourse, or cases of rape. Use of emergency contraception could halve the number of unintended pregnancies and the consequent need for abortion, but unfortunately many medical professionals and the public are not aware of it. Two methods are available for emergency contraception, namely emergency contraception pills (ECPs and copper-bearing intrauterine devices (Cu-IUDs. There are two regimens of ECP, the levonorgestrel regimen and combined regimen. The levonorgestrel regimen is preferred as it is more effective and causes less side effects. ECPs should be administered as soon as possible after unprotected or inadequately protected sex, being most effective if initiated within 24 hours. Cu-IUDs can be inserted up to 5 days after unprotected sexual intercourse. Emergency contraception mainly works by preventing fertilization, and does not interrupt and established pregnancy. Emergency contraception is very safe, therefore can be offered to women who have had unprotected intercourse and wish to prevent pregnancy. It must only be used as a backup method of birth control. (Med J Indones. 2013;22:248-52. doi: 10.13181/mji.v22i4.609Keywords: Birth control, copper-IUD, emergency contraception, emergency contraceptive pills, levonorgestrel

    To evaluate the representativeness of controls in an ongoing, population-based, case-control study of birth defects in 10 centers across the United States, researchers compared 1997-2003 birth certificate data linked to selected controls (n = 6,681) and control participants (n = 4,395) with those from their base populations (n = 2,468,697). Researchers analyzed differences in population characteristics (e.g., percentage of births at > or =2,500 g) for each group. Compared with their base populations, control participants did not differ in distributions of maternal or paternal age, previous livebirths, maternal smoking, or diabetes, but they did differ in other maternal (i.e., race/ethnicity, education, entry into prenatal care) and infant (i.e., birth weight, gestational age, and plurality) characteristics. Differences in distributions of maternal, but not infant, characteristics were associated with participation by selected controls. Absolute differences in infant characteristics for the base population versus control participants were controls from hospitals compared with centers that selected controls from electronic birth certificates. These findings suggest that control participants in the National Birth Defects Prevention Study generally are representative of their base populations. Hospital-based control selection may slightly underascertain infants affected by certain adverse birth outcomes.

  8. Birth control in the Third World - is it Neo-colonialism in disguise?

    Science.gov (United States)

    Measham, A R

    1974-01-01

    This paper challenges the simplistic, though popular, view that the world must choose between programs for fertility control and socioeconomic development; between the Malthusian focus on population control and the Marxist one on exploitation control. In the developing world there is great need for achievement on both fronts through a broad range of policies and programs. It is inaccurate and injust to label social policies aimed at ensuring stabilization of world population size in the next century as neoMalthusian. It is also a fact that Soviet scholars now consider excessive population growth a problem for development planners. Accusations that birth control programs advocated for the Third World represent race genocide are based on erroneous thinking. Those who advocate contraception want to make it available to less privileged members of both more and less developed societies. It is not a neo-colonialist plot against the Third World: China herself has a population policy. On the other hand, the Roman Catholic Church, in common with some socialist countries, seeks to inhibit international action aimed at spreading contraception. Even though there is no optimal strategy for development per se, it is understandable that most developmental aid is viewed in terms of a desired model of social change by the donor countries. However, leadership by the U.S. in providing family planning assistance since the 1950s should not be construed as an imperialist plot. No group has the right to impose its preferences on the Third World. A rational approach towards development suggests that 1) developing countries should accept aid without undue concern of the motives involved in the giving of aid; and 2) the development assistance by donors should be increased, made more easily available, should be more multilateral, given without strings attached, and generally made less discriminatory. Birth control assistance will succeed only if general development assistance is redefined

    Preterm birth is the leading cause of neonatal death and handicap in survivors. Although twins are found in 1.5% of pregnancies they account for about 25% of preterm births. Randomized controlled trials in singleton pregnancies reported that the prophylactic use of progestogens, cervical cerclage and cervical pessary reduce significantly the rate of early preterm birth. In twin pregnancies, progestogens and cervical cerclage have been shown to be ineffective in reducing preterm birth. The objective of this study was to test the hypothesis that the insertion of a cervical pessary in twin pregnancies would reduce the rate of spontaneous early preterm birth. This was a multicenter, randomized controlled trial in unselected twin pregnancies of cervical pessary placement from 20(+0)-24(+6) weeks' gestation until elective removal or delivery vs. expectant management. Primary outcome was spontaneous birth control groups in rates of spontaneous birth birth. Copyright © 2016 Elsevier Inc. All rights reserved.

    2015-07-01

    We analyzed a nationwide registry of all pregnancies in Uruguay during 2007-2013 to assess the impact of three types of tobacco control policies: (1) provider-level interventions aimed at the treatment of nicotine dependence, (2) national-level increases in cigarette taxes, and (3) national-level non-price regulation of cigarette packaging and marketing. We estimated models of smoking cessation during pregnancy at the individual, provider and national levels. The rate of smoking cessation during pregnancy increased from 15.4% in 2007 to 42.7% in 2013. National-level non-price policies had the largest estimated impact on cessation. The price response of the tobacco industry attenuated the effects of tax increases. While provider-level interventions had a significant effect, they were adopted by relatively few health centers. Quitting during pregnancy increased birth weight by an estimated 188 g. Tobacco control measures had no effect on the birth weight of newborns of non-smoking women. Copyright © 2015 Elsevier B.V.

  16. The effect of parental involvement laws on teen birth control use.

    Sabia, Joseph J; Anderson, D Mark

    2016-01-01

    In Volume 32, Issue 5 of this journal, Colman, Dee, and Joyce (CDJ) used data from the National Youth Risk Behavior Surveys (NYRBS) and found that parental involvement (PI) laws had no effect on the probability that minors abstain from sex or use contraception. We re-examine this question, augmenting the NYRBS with data from the State Youth Risk Behavior Surveys (SYRBS), and use a variety of identification strategies to control for state-level time-varying unmeasured heterogeneity. Consistent with CDJ, we find that PI laws have no effect on minor teen females' abstinence decisions. However, when we exploit additional state policy variation unavailable to CDJ and use non-minor teens as a within-state control group, we find evidence to suggest that PI laws are associated with an increase in the probability that sexually active minor teen females use birth control.

    Access control policies are essential to determine who is allowed to access data in a system without compromising the data's security. However, applications inside a distributed environment may require those policies to be dependent on the actual content of the data, the flow of information, while...... also on other attributes of the environment such as the time. In this paper, we use systems of Timed Automata to model distributed systems and we present a logic in which one can express time-dependent policies for access control. We show how a fragment of our logic can be reduced to a logic...... that current model checkers for Timed Automata such as UPPAAL can handle and we present a translator that performs this reduction. We then use our translator and UPPAAL to enforce time-dependent policy-based access control on an example application from the aerospace industry....

    Maternal mortality continues to claim the lives of thousands of women in Latin America despite the availability of effective treatments to avert maternal death. In the past, efforts to acknowledge cultural diversity in birth practices had not been clearly integrated into policy. However, in Otavalo (Ecuador) a local hospital pioneered the implementation of the ‘Vertical Birth’—a practical manifestation of an intercultural health policy aimed at increasing indigenous women’s access to maternity care. Drawing on agenda-setting theory, this qualitative research explores how the vertical birth practice made it onto the local policy agenda and the processes that allowed actors to seize a window of opportunity allowing the vertical birth practice to emerge. Our results show that the processes that brought about the vertical birth practice took place over a prolonged period of time and resulted from the interplay between various factors. Firstly, a maternal health policy community involving indigenous actors played a key role in identifying maternal mortality as a policy problem, defining its causes and framing it as an indigenous rights issue. Secondly, previous initiatives to address maternal mortality provided a wealth of experience that gave these actors the knowledge and experience to formulate a feasible policy solution and consolidate support from powerful actors. Thirdly, the election of a new government that had incorporated the demands of the indigenous movement opened up a window of opportunity to push intercultural health policies such as the vertical birth. We conclude that the socioeconomic and political changes at both national and local level allowed the meaningful participation of indigenous actors that made a critical contribution to the emergence of the vertical birth practice. These findings can help us advance our knowledge of strategies to set the agenda for intercultural maternal health policy and inform future policy in similar settings

    Objective To determine whether training traditional birth attendants to manage several common perinatal conditions could reduce neonatal mortality in the setting of a resource poor country with limited access to healthcare. Design Prospective, cluster randomised and controlled effectiveness study. Setting Lufwanyama, an agrarian, poorly developed district located in the Copperbelt province, Zambia. All births carried out by study birth attendants occurred at mothers’ homes, in rural village settings. Participants 127 traditional birth attendants and mothers and their newborns (3559 infants delivered regardless of vital status) from Lufwanyama district. Interventions Using an unblinded design, birth attendants were cluster randomised to intervention or control groups. The intervention had two components: training in a modified version of the neonatal resuscitation protocol, and single dose amoxicillin coupled with facilitated referral of infants to a health centre. Control birth attendants continued their existing standard of care (basic obstetric skills and use of clean delivery kits). Main outcome measures The primary outcome was the proportion of liveborn infants who died by day 28 after birth, with rate ratios statistically adjusted for clustering. Secondary outcomes were mortality at different time points; and comparison of causes of death based on verbal autopsy data. Results Among 3497 deliveries with reliable information, mortality at day 28 after birth was 45% lower among liveborn infants delivered by intervention birth attendants than control birth attendants (rate ratio 0.55, 95% confidence interval 0.33 to 0.90). The greatest reductions in mortality were in the first 24 hours after birth: 7.8 deaths per 1000 live births for infants delivered by intervention birth attendants compared with 19.9 per 1000 for infants delivered by control birth attendants (0.40, 0.19 to 0.83). Deaths due to birth asphyxia were reduced by 63% among infants delivered by

    Kapor-stanulovic, N; Beric, B M

    1983-09-01

    The Christian Orthodox Church has 100-150 million baptized members worldwide. Its official position on fertility regulation is little known among nontheologians. The Christian Orthodox Church is resolutely opposed to all attempts to permit induced abortion, and has been since its earliest history. In the 4th century the aborting woman was considered in the same category as a murderer, and the position was reiterated through the centuries in the canons of the Church. However, the common practice of Church members differed greatly from the official position. During the Roman period and the 1st years of the Christian era, abortion and the exposure of newborns were very common. Many of the earlier arguments in favor of abortion that were countered by the Church are still offered. The liberalization of abortion legislation in the US was opposed by American Christian Orthodox Church members. The Church's position on contraception is less well known than its stand on abortion. Several official publications have condemned family planning, regarding it as a form of prostitution within the family and as a sin. The official position of the Greek Orthodox Church was set forth in an encyclical written in 1937, which recommended abstinence as the only legal method of avoiding conception. The position of the Christian Orthodox Church on abortion and contraception is fundamentally identical to that of the Roman Catholic Church. Because the position of the Christian Orthodox Church on birth control, which has been fixed for centuries, has not been officially debated and has not been communicated to the members, it has not fully guided daily life. One might suppose that members of the Christian Orthodox Church are freer of church control of their fertility behavior than are Catholics.

    After declining for over a decade, the birth rate in the United States for adolescents aged 15-19 years increased by 3% in 2006 and 1% again in 2007. We examined demographic and policy reasons for this trend at state level. With data merged from multiple sources, descriptive analysis was used to detect state-level trends in birth rate and policy changes from 2000 to 2006, and variations in the distribution of teen birth rates, sex education, and family planning service policies, and demographic features across each state in 2006. Regression analysis was then conducted to estimate the effect of several reproductive health policies and demographic features on teen birth rates at the state level. Instrument variable was used to correct possible bias in the regression analysis. Medicaid family planning waivers were found to reduce teen birth rates across all ages and races. Abstinence-only education programs were found to cause an increase in teen birth rates among white and black teens. The increasing Hispanic population is another driving force for high teen birth rates. Both demographic factors and policy changes contributed to the increase in teen birth rates between 2000 and 2006. Future policy and behavioral interventions should focus on promoting and increasing access to contraceptive use. Family planning policies should be crafted to address the special needs of teens from different cultural backgrounds, especially Hispanics. Copyright 2010 Society for Adolescent Health and Medicine.

  9. The politics of birth control, 1920-1940: the impact of professionals.

    Science.gov (United States)

    Gordon, L

    1975-01-01

    Before the 1920s, a birth control movement arose in the United States out of socialist, feminist, and other radical groups concerned with women's rights and sexual freedom. After 1920 the birth control movement became gradually transformed into a respectable, nonradical reform cause, the recipient of large grants from big business, with women's rights secondary to an overriding concern with medical health and population control. This transformation was achieved through the professionalization of the birth control movement-that is, its takeover by professional experts, almost all male, in place of the radical amateur women, fighting for their own interests, who initiated it. The article examines two groups of professionals who were particularly influential in this transformation: doctors and academic eugenists. The former made birth control a medical issue, held back the development of popular sex education, and stifled a previously developing feminist approach to women's birth control needs. The later contributed racism to the birth control movement, helping to transform it into a population control movement with racist and anti-feminist overtones. Both groups, while they made contributions to the technology of contraception, simultaneously held back the spread of birth control by transforming the campaign for it from a popular, participatory cause to a professional staff lobbying operation.

    We sought to (1) survey sexually intact street dogs for a wide range of diseases in three cities in Rajasthan, India and (2) evaluate links between the health of non-treated dogs and both the presence and duration of animal birth control (ABC) programs. ABC regimes sterilize and vaccinate stray dogs in an attempt to control their population and the spread of rabies. They are commonly suggested to improve the health of those dogs they serve, but here we provide evidence that these benefits also extend to untreated dogs in the community. Viral and bacterial disease seroprevalences were assessed in 240 sexually intact street dogs from Jaipur, Jodhpur, and Sawai Madhopur cities in October and September 2011. Those individuals and 50 additional dogs were assessed for the presence of ticks, fleas, fight wounds, and given body condition scores. Dogs in cities with an ABC program had with significantly (pdogs in cities with ABC programs had significantly higher prevalence of Brown Dog Tick (Rhipicephalus sanguineus) infestations. Canine parvovirus and Brucella canis prevalences were not significantly different between cities. This study is the first to demonstrate the health benefits of ABC on non-vaccinated diseases and non-treated individuals. Copyright © 2013 The Authors. Published by Elsevier B.V.

    Birth registration and obtaining physical birth certificates impose major challenges in developing countries, with impact on child and community health, education, planning, and all levels of development. However despite initiatives, universal registration is elusive, leading to calls for new approaches to understanding the decisions of parents. In this paper, we report results of a survey of students in grades six to eight (age ~12-16) in an under-registered area of Kenya regarding their own understanding of registration issues and their suggestions for improvement. These students were selected because they themselves were also nearing the age for high school enrollment/entrance examinations, which specifically requires possession of a birth certificate. This assessment was also a companion to our previous representative survey of adults in the same Kenyan region, allowing for parent-child comparison. Results supported previous research, showing that only 43% had birth certificates. At the same time, despite these low totals, students were themselves quite aware of registration factors and purposes. The students also made quite prescient sources for understanding their households' motivations, with many of their suggestions-for focus on communication of pragmatic benefits, or automatic measures shifting responsibility from parents-mirroring our own previous suggestions, and showing a level of pragmatism not witnessed when surveying their parents. This paper therefore adds evidence to the discussion of registration policy planning. More generally, it also builds on an important trend regarding the treatment of children as stakeholders and important sources of information, and raising an intriguing new avenue for future research.

    Previous studies of the use of birth control by sexually active single women tend to emphasize family background and aspirations, and restrict their attention to teenagers. We elaborate this framework by considering how labor market experiences might shape the birth control practices of women in their late teens and twenties. Data from the National Longitudinal Survey of Labor Force Experiences--Youth Cohort provide evidence that employment histories and wages influence birth control practices, net of the effects of family background, aspirations, and educational attainment. Several pronounced racial and ethnic differences are found.

    2011-01-01

    In the first half of the twentieth century, birth control advocates used the mass media to reframe contraception from a private, secret matter to an acceptable part of life fit for public discussion. Although their campaign began in print, they quickly embraced the more far-reaching medium of film to deliver their message. This article argues that birth control advocates circumvented the Comstock Act in the early decades of the twentieth century by taking up this new medium as part of a long-running strategy to publicize the birth control movement. Their efforts shaped both the public debate on the topic and the development of motion picture censorship.

    Full Text Available Abstract Background This study assesses the consistency of responses among women regarding their beliefs about the mechanisms of actions of birth control methods, beliefs about when human life begins, the intention to use or not use birth control methods that they believe may act after fertilization or implantation, and their reported use of specific methods. Methods A questionnaire was administered in family practice and obstetrics and gynecology clinics in Salt Lake City, Utah, and Tulsa, Oklahoma. Participants included women ages 18–50 presenting for any reason and women under age 18 presenting for family planning or pregnancy care. Analyses were based on key questions addressing beliefs about whether specific birth control methods may act after fertilization, beliefs about when human life begins, intention to use a method that may act after fertilization, and reported use of specific methods. The questionnaire contained no information about the mechanism of action of any method of birth control. Responses were considered inconsistent if actual use contradicted intentions, if one intention contradicted another, or if intentions contradicted beliefs. Results Of all respondents, 38% gave consistent responses about intention to not use or to stop use of any birth control method that acted after fertilization, while 4% gave inconsistent responses. The corresponding percentages for birth control methods that work after implantation were 64% consistent and 2% inconsistent. Of all respondents, 34% reported they believed that life begins at fertilization and would not use any birth control method that acts after fertilization (a consistent response, while 3% reported they believed that life begins at fertilization but would use a birth control method that acts after fertilization (inconsistent. For specific methods of birth control, less than 1% of women gave inconsistent responses. A majority of women (68% or greater responded accurately about the

    Ess, Silvia M; Schneeweiss, Sebastian; Szucs, Thomas D

    2003-01-01

    In the last 20 years, expenditures on pharmaceuticals - as well as total health expenditures - have grown faster than the gross national product in all European countries. The aim of this paper was to review policies that European governments apply to reduce or at least slow down public expenditure on pharmaceutical products. Such policies can target the industry, the wholesalers and retailers, prescribers, and patients. The objectives of pharmaceutical policies are multidimensional and must take into account issues relating to public health, public expenditure and industrial incentives. Both price levels and consumption patterns determine the level of total drug expenditure in a particular country, and both factors vary greatly across countries. Licensing and pricing policies intend to influence the supply side. Three types of pricing policies can be recognised: product price control, reference pricing and profit control. Profit control is mainly used in the UK. Reference pricing systems were first used in Germany and The Netherlands and are being considered in other countries. Product price control is still the most common method for establishing the price of drugs. For the aim of fiscal consolidation, price-freeze and price-cut measures have been frequently used in the 1980s and 1990s. They have affected all types of schemes. For drug wholesalers and retailers, most governments have defined profit margins. The differences in price levels as well as the introduction of a Single European Pharmaceutical Market has led to the phenomenon of parallel imports among member countries of the European Union. This may be facilitated by larger and more powerful wholesalers and the vertical integration between wholesalers and retailers. To control costs, the use of generic drugs is encouraged in most countries, but only few countries allow pharmacists to substitute generic drugs for proprietary brands. Various interventions are used to reduce the patients' demand for drugs by

    To examine (1) if the use of benzodiazepines and antidepressants during pregnancy may increase the risk of preterm birth and/or low birth weight (LBW), and, if yes, (2) which types of benzodiazepines or antidepressants have stronger influences. A case-control study was performed using a large claims database in Japan. Cases were mothers who had given birth to preterm and/or LBW infants between 2005 and 2014 (737 with preterm births and 1615 with LBW). Controls were mothers who had neither experienced preterm birth nor given birth to an LBW infant. Overall, 42 058 births were included. The maternal use of benzodiazepines was significantly associated with an increased risk of preterm birth (adjusted odds ratio [OR], 2.03; 95% confidence interval [CI], 1.11-3.69, P preterm deliveries (adjusted OR, 0.57; 0.08-4.16) and LBW (adjusted OR, 0.56; 0.14-2.29). Benzodiazepine use was associated with increased risk of preterm birth but not with LBW. Antidepressant use was not associated with both preterm deliveries and LBW. © 2018 John Wiley & Sons Australia, Ltd.

    Preterm birth is a leading cause of perinatal morbidity and mortality worldwide, resulting in a pressing need to identify risk factors leading to effective interventions. Limited evidence suggests potential relationships between maternal sleep or vital exhaustion and preterm birth, yet the literature is generally inconclusive. We examined the relationship between maternal sleep duration and vital exhaustion in the first six months of pregnancy and spontaneous (non-medically indicated) preterm birth among 479 Peruvian women who delivered a preterm singleton infant (exhaustion were ascertained through in-person interviews. Spontaneous preterm birth cases were further categorized as those following either spontaneous preterm labor or preterm premature rupture of membranes. In addition, cases were categorized as very (exhaustion was also associated with increased odds of preterm birth (aOR = 2.41; 95% CI 1.79-3.23) compared to no exhaustion (Ptrend exhaustion on the odds of spontaneous preterm birth. The results of this case-control study suggest maternal sleep duration, particularly short sleep duration, and vital exhaustion may be risk factors for spontaneous preterm birth. These findings call for increased clinical attention to maternal sleep and the study of potential intervention strategies to improve sleep in early pregnancy with the aim of decreasing risk of preterm birth.

    Science.gov (United States)

    1980-04-23

    Some leading cadres in Wenzhou Municipaity, Zhejian refuse to practice birth control instead of supporting this effort. The wife of Comrade Lin Xiannen, a member of the Standing Committee of the party municipal committee, gave birth to a 3rd child last March. Up to now, they have refused to practice birth control. Wang Danwen, a member of the provincial revolutionary committee and deputy director of the municipal posts and telecommunications bureau, did not break the news that she was pregnant with her 3rd child until the 8th month of her pregnancy. Following the example of these leading cadres, Lin Xiaohua, a cadre of the Wenzhou prefectural intermediate court of justice, and Sun Lianfang (a party member and cadre) gave birth to their 3rd child. These cases have been reported many times to the municpal committee leadership. In Wenzhou Municipality at this time, many young people got married too early and many young women are pregnant too early. The actions that were subsequently taken against the cadres who refused to practice birth control and were having too many children are outlined. The fundamental reason why birth control work in Wenzhou is lagging behind is that some cadres fail to practice family planning and urge their sons and daughters to marry too early. According to an investigation, 496 of the 728 cadres, or 68.1%, in 6 areas in Ruian County have 3 or more children.

    To investigate the relation of prior intracervical procedures with very preterm birth. A population-based case-control study. The study was conducted in Australia between 2002 and 2004. Three hundred and forty-five women having a medically indicated and 236 having a spontaneous singleton birth between 20 and 31 weeks of gestation and 796 women selected randomly from all those giving birth at ≥37 weeks of gestation. Interview data were analysed using logistic regression. Very preterm birth. Very preterm birth was significantly associated with having any intracervical procedure [adjusted odds ratio (AOR) 2.07; 95% confidence interval (CI) 1.6-2.7], in particular curettage associated with abortion (AOR 1.80; 95% CI 1.2-2.6). Assisted reproductive technology procedures were significantly associated with medically indicated very preterm birth (AOR 3.07; 95% CI 1.8-5.3) and treatments for precancerous cervical changes were significantly associated with spontaneous very preterm birth, as follows: conization/cone biopsy (AOR 3.33; 95% CI 1.8-6.2) and cauterization/ablation (AOR 2.27; 95% CI 1.4-3.8). Suction aspiration for abortion, abnormal Pap smear without treatment and abortion without instrumentation were not associated with very preterm birth. Intracervical procedures are associated with very preterm birth. Notably, curettage rather than any other procedure associated with abortion appears to be implicated in the risk. The introduction of infection during cervical procedures may be the common link with risks found. Changing clinical practice in the management of abortion and human papillomavirus vaccination may lead to lowering the risks of very preterm birth. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

    The Tobacco Control Scorecard, published in 2004, presented estimates of the effectiveness of different policies on smoking rates. Since its publication, new evidence has emerged. We update the Scorecard to include recent studies of demand-reducing tobacco policies for high-income countries. We include cigarette taxes, smoke-free air laws, media campaigns, comprehensive tobacco control programs, marketing bans, health warnings, and cessation treatment policies. To update the 2004 Scorecard, a narrative review was conducted on reviews and studies published after 2000, with additional focus on 3 policies in which previous evidence was limited: tobacco control programs, graphic health warnings, and marketing bans. We consider evaluation studies that measured the effects of policies on smoking behaviors. Based on these findings, we derive estimates of short-term and long-term policy effect sizes. Cigarette taxes, smoke-free air laws, marketing restrictions, and comprehensive tobacco control programs are each found to play important roles in reducing smoking prevalence. Cessation treatment policies and graphic health warnings also reduce smoking and, when combined with policies that increase quit attempts, can improve quit success. The effect sizes are broadly consistent with those previously reported for the 2004 Scorecard but now reflect the larger evidence base evaluating the impact of health warnings and advertising restrictions.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

  6. The effects of programs of birth control education on the practice of induced abortion in Japan.

    The impact of family planning education on abortion in Japan is discussed. At the present time, Japan has a low birthrate (18.5% population) and a low death rate (7.1% population) which allows an annual average 1% natural increase rate. The birthrate has been halved in 30 years. Although it is a common assertion that Japan solved its population problem by induced abortion, this view is both inaccurate and a simplification of the actual demographic situation. There are at least 3 important demographic factors that contributed to the reduction of the Japanese fertility: 1) the decline of the age-specific fertility among married women achieved by birth control methods, including abortion; 2) emigration, especially from the rural areas; and 3) the change in the marriage pattern of the population. The present family planning movement was started in the 1920s by the socialists and the leaders of the labor movement, but the government discouraged the movement and continued the strong pronatalist policy. After World War II, the Eugenic Protection Law was enacted in 1948. In 1951, as a result of the increasing numbers of reported induced abortions, the government officially disapproved of induced abortion as a usual means of birth control and endorsed an official plan to promote conception control. From 1950 to 1965, women using contraceptive methods increased from 19.5% to 51.9%. From 1950 to 1965, women who had experienced induced abortion decreased from 35.6% to 29.7%. But during that period, the percentage of women who had experienced induced abortion fluctuated up and down. In fact, induced abortions have been on the upswing since 1961. Having no data on the rate of illegal induced abortion, the observed reduction of abortion in favor of contraception is always open to alternative explanations in addition to the family planning programs. It appears that there has been a greater impact of family planning education in cities than in rural areas. Early reduction of the

    Full Text Available Abstract Background Birth weight plays an important role in infant mortality and morbidity, childhood development, and adult health. To date there are contradictory results regarding the role of physical activity on birth weight. In addition, it is questioned whether exercise during second and third trimesters of pregnancy might affect gestational age and increase the risk of preterm delivery. Hence, the purpose of this study was to examine the effect of a supervised exercise-program on birth weight, gestational age at delivery and Apgar-score. Methods Sedentary, nulliparous pregnant women (N = 105, mean age 30.7 ± 4.0 years, pre-pregnancy BMI 23.8 ± 4.3 were randomized to either an exercise group (EG, n = 52 or a control group (CG, n = 53. The exercise program consisted of supervised aerobic dance and strength training for 60 minutes, twice per week for a minimum of 12 weeks, with an additional 30 minutes of self-imposed physical activity on the non-supervised week-days. Results There was no statistically significant difference between groups in mean birth weight, low birth weight ( Conclusion Aerobic-dance exercise was not associated with reduction in birth weight, preterm birth rate or neonatal well-being.

    In this paper, we propose exploited models with stage structure for the dynamics in a fish population for which periodic birth pulse and pulse fishing occur at different fixed time. Using the stroboscopic map, we obtain an exact cycle of system, and obtain the threshold conditions for its stability. Bifurcation diagrams are constructed with the birth rate (or pulse fishing time or harvesting effort) as the bifurcation parameter, and these are observed to display complex dynamic behaviors, including chaotic bands with period windows, period-doubling, multi-period-halving and incomplete period-doubling bifurcation, pitch-fork and tangent bifurcation, non-unique dynamics (meaning that several attractors or attractor and chaos coexist) and attractor crisis. This suggests that birth pulse and pulse fishing provide a natural period or cyclicity that make the dynamical behaviors more complex. Moreover, we show that the pulse fishing has a strong impact on the persistence of the fish population, on the volume of mature fish stock and on the maximum annual-sustainable yield. An interesting result is obtained that, after the birth pulse, the population can sustain much higher harvesting effort if the mature fish is removed as early as possible

  11. Feminism, biomedicine and the 'reproductive destiny' of women in clinical texts on the birth control pill.

    2017-10-18

    The birth control pill is one of the most popular forms of contraception in North America and has been a key player in women's rights activism for over 50 years. In this paper, I conduct a feminist deconstructive analysis of 12 biomedical texts on the birth control pill, published between 1965 and 2016. This study is situated amongst the feminist scholarship that challenges the representation of women's bodies in biomedicine. Findings suggest that clinical texts on the birth control pill continue to universalise women's lives and experiences, and essentialise them based on their reproductive capacities. One way the texts accomplish this is by making women absent or passive in the literature thereby losing concern for the diversity of their lives, interpretations and identities as more than reproductive beings. The consequence of such representations is that biomedical texts disseminate limited forms of knowledge, in particular concerning definitions of 'natural' and 'normal' behaviour, with important consequences for the embodied experiences of women.

    Skilled birth attendance is critical in the provision of child birth related services. Yet, literature is scanty on the outcomes of child birth related complications in situations where majority of women deliver under the care of non-skilled birth attendants compared to those who are assisted by skilled providers. The study sought to assess the nature of childbirth related complications among the skilled and the non-skilled birth attendants in Western Kenya. A case-control study was conducted among women aged 15-49 years at the household. Controls were individually matched to cases on the basis of age and socio-economic status. A total of 294 cases and 291 controls were interviewed. Data were collected on various demographic and socio-economic characteristics and women's perception on the quality of care. All independent variables were analysed initially in bivariate models and those that were significantly associated with obstetric complications were included in multiple logistic regression model in order to control for confounding factors. Odds ratios (ORs), with 95% confidence intervals, were computed to show the association between the occurrence, magnitude and the extent to which child birth related complications were managed. Demographic and socio-economic characteristics of the cases and controls were similar. About 52% of the deliveries were assisted by skilled birth attendants while non-skilled providers attended to 48% of them. The odds of the occurrence of obstetric complications were greater among the women who were attended to by skilled providers in health facilities: adjusted odds ratio (AOR): 1.32 (CI 0.95, 1.84) than among those who were assisted by unskilled birth attendants, AOR 0.76 (CI 0.55, 1.06). Undignified care, high delivery and transport costs and fear of hospital procedures such as HIV tests and mishandling of the placenta were cited as some of the barriers to facility deliveries. Skilled birth attendants in facilities were associated

    Nearly all women shower or take baths during early pregnancy; however, bathing habits (i.e., shower and bath length and frequency) may be related to the risk of maternal hyperthermia and exposure to water disinfection byproducts, both of which are suspected to increase risk for multiple types of birth defects. Thus, we assessed the relationships between bathing habits during pregnancy and the risk for several nonsyndromic birth defects in offspring. Data for cases with one of 13 types of birth defects and controls from the National Birth Defects Prevention Study delivered during 2000-2007 were evaluated. Logistic regression analyses were conducted separately for each type of birth defect. There were few associations between shower frequency or bath frequency or length and risk for birth defects in offspring. The risk for gastroschisis in offspring was increased among women who reported showers lasting ≥15 compared to <15 minutes (adjusted odds ratio: 1.43, 95% confidence interval: 1.18-1.72). In addition, we observed modest increases in the risk for spina bifida, cleft lip with or without cleft palate, and limb reduction defects in offspring of women who showered ≥15 compared to <15 minutes. The results of comparisons among more specific categories of shower length (i.e., <15 minutes versus 15-19, 20-29, and ≥ 30 minutes) were similar. Our findings suggest that shower length may be associated with gastroschisis, but the modest associations with other birth defects were not supported by analyses of bath length or bath or shower frequency. Given that showering for ≥15 minutes during pregnancy is very common, further evaluation of the relationship between maternal showering habits and birth defects in offspring is worthwhile.

    Childbirth fear is the most common underlying reason for requesting a caesarean section without medical reason. The aim of this randomised controlled study was to investigate birth preferences in women undergoing treatment for childbirth fear, and to investigate birth experience and satisfaction with the allocated treatment. Pregnant women classified with childbirth fear (≥60 on the Fear Of Birth Scale) (n=258) were recruited at one university hospital and two regional hospitals over one year. The participants were randomised (1:1) to intervention (Internet-based Cognitive Behaviour Therapy (ICBT)) (n=127) or standard care (face-to-face counselling) (n=131). Data were collected by questionnaires in pregnancy week 20-25 (baseline), week 36 and two months after birth. Caesarean section preference decreased from 34% to 12% in the ICBT group and from 24% to 20% in the counselling group. Two months after birth, the preference for caesarean increased to 20% in the ICBT group and to 29% in the counselling group, and there was no statistically significant change over time. Women in the ICBT group were less satisfied with the treatment (OR 4.5). The treatment had no impact on or worsened their childbirth fear (OR 5.5). There were no differences between the groups regarding birth experience. Women's birth preferences fluctuated over the course of pregnancy and after birth regardless of treatment method. Women felt their fear was reduced and were more satisfied with face-to-face counselling compared to ICBT. A higher percentage were lost to follow-up in ICBT group suggesting a need for further research. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

    Introduction Smoking remains the leading cause of preventable death in the USA but can be reduced through policy interventions. Computational models of smoking can provide estimates of the projected impact of tobacco control policies and can be used to inform public health decision making. We outline a protocol for simulating the effects of tobacco policies on population health outcomes. Methods and analysis We extend the Smoking History Generator (SHG), a microsimulation model based on data from the National Health Interview Surveys, to evaluate the effects of tobacco control policies on projections of smoking prevalence and mortality in the USA. The SHG simulates individual life trajectories including smoking initiation, cessation and mortality. We illustrate the application of the SHG policy module for four types of tobacco control policies at the national and state levels: smoke-free air laws, cigarette taxes, increasing tobacco control programme expenditures and raising the minimum age of legal access to tobacco. Smoking initiation and cessation rates are modified by age, birth cohort, gender and years since policy implementation. Initiation and cessation rate modifiers are adjusted for differences across age groups and the level of existing policy coverage. Smoking prevalence, the number of population deaths avoided, and life-years gained are calculated for each policy scenario at the national and state levels. The model only considers direct individual benefits through reduced smoking and does not consider benefits through reduced exposure to secondhand smoke. Ethics and dissemination A web-based interface is being developed to integrate the results of the simulations into a format that allows the user to explore the projected effects of tobacco control policies in the USA. Usability testing is being conducted in which experts provide feedback on the interface. Development of this tool is under way, and a publicly accessible website is available at http

    The myth that projects population control as the cure-all for all social and economic problems has a class bias. The emphasis of planners on population control is an attempt to weaken the class struggle in India by absolving the exploiters of the responsibility for perpetuating inequalities and shifting the blame from the capitalist order to the people. 2 major issues in the family planning program are considered: 1) that overpopulation is a major cause of poverty; and 2) that persuading people to accept the small family norm is the only way that population growth may be controlled. The socio-political content of these issues are examined, and it is emphatically suggested that eradication of poverty and unemployment as well as guarantees against insecurity, sickness, and the death of children must be demanded as a prerequisite for accepting the small family norm.

    This study aimed to investigate the association between periodontitis in pregnant women and adverse pregnancy outcomes by heeding confounding risk factors for preterm low birth weight infants. This study was reported according to The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement. A case-control study was conducted. Medical records of all pregnant women attending a prenatal care clinic were screened. Those between 21 and 34 years and gestational age of 28-32 weeks were initially enrolled in the study. The exclusion criteria were then applied: diabetes mellitus, genitourinary tract infections, or HIV infection; previous multiple gestations; previous preterm birth/low birth weight infants; in vitro fertilization procedures; placental, cervical/uterine abnormalities; history of infertility; history of drug abuse; and any medical conditions that required antibiotics prophylaxis. Patients' anthropometric, demographic, and behavioral characteristics were collected. The periodontal clinical parameters were obtained from six sites per tooth: clinical attachment level, probing pocket depth, dental plaque index, and gingival bleeding index. Women were then allocated into two groups: mothers of preterm and/or low birth weight newborns (cases) and mothers of full-term and normal birth weight newborns (controls). Periodontal clinical parameters were analyzed and reported separately for each group, and no significant differences were observed (p > 0.05). Logistic regression analysis revealed that periodontal clinical parameters were not associated with the adverse pregnancy outcomes. After controlling for confounding factors, our results suggest that maternal periodontal disease is not a risk factor associated with preterm low birth weight infants.

    Since the 1990s, evidence has been raised that there is an association between maternal periodontal disease and undesirable gestational events, for example low birth weight; this issue is controversial. To evaluate whether there is an association between maternal periodontitis and low birth weight (LBW). A case-control study was carried out on 951 mothers that had been cared for by the Brazilian Unified Health System in Petrolina-PE and Juazeiro-BA, Brazil. The case group (n = 269) consisted of mothers of newborns with birth weight <2500 g and a control group (n = 682) of mothers of newborns with birth weight ≥2500 g. An interview was realized, using a questionnaire as well as a full mouth examination to diagnose the periodontal condition. Women who had at least four teeth with probing depth ≥4 mm and clinical attachment loss ≥3 mm, with bleeding on probing at the same site, were diagnosed with periodontitis. The birth weight was obtained through the hospital book record. The main association was evaluated using the multivariate regression model, considering confounders. The frequency of periodontitis was 16.4% (case group) and 17.4% (control group). Periodontitis did not show an association with LBW (ORcrude = 0.92; 95% CI = 0.63-1.35), even after adjustment for the following confounders: maternal age, pre-gestational body mass index, number of pre-natal consultations, number of pregnancies, maternal schooling level, smoking habit during pregnancy and hypertension (ORadjusted = 1.00; 95% CI = 0.61-1.68). The findings of this study showed no association between maternal periodontal disease and low birth weight, even after appropriate adjustments for confounding factors.

    Poor oral health, such as periodontal (gum) disease, has been found to be associated with an increased risk of adverse pregnancy outcomes including preterm birth, low birth weight, and neonatal and infant mortality, especially in low-and middle-income countries. However, there is little or no access to preventive dental care in most low-and middle-income countries. We propose to develop and test a "Mouth Rinse Intervention" among pregnant women to prevent the progression of periodontal disease during pregnancy and reduce adverse birth and neonatal outcomes in a rural county of China. This is a randomized controlled clinical trial. A sample of 468 (234 in each arm of the study) women in early pregnancy with periodontal disease will be recruited for the study. Periodontal disease will be diagnosed through the methods of Periodontal Screening and Recording. All women diagnosed with periodontal disease will be randomly allocated into the intervention or control group. Women assigned in the intervention group will be provided with non-alcohol antimicrobial mouth rinse containing cetylpyridinium chloride throughout the pregnancy and oral health education. Women in the control group will receive a package of tooth brush and paste, plus oral hygiene education. Women will be followed-up to childbirth until the 42nd day postpartum. The main outcomes include mean birthweight (gram) and mean gestational age (week). Compared with conventional mechanical 'scaling and root planning' periodontal treatment during pregnancy, our proposed mouth rinse intervention could be a simple, cost-effective, and sustainable solution to improve both mother's oral health and neonate outcomes. If the mouth rinse is confirmed to be effective, it would demonstrate great potential for the application in other low- or middle-income countries to prevent adverse birth outcomes such as preterm birth and low birth weight and to reduce neonatal and infant mortality.

    1995-12-31

    The legal basis of the Swiss air pollution control policy is set by the Federal Law on the Protection of the Environment, which came into force in 1985. It aims to protect human beings, animals and plants, their biological communities and habitats against harmful effects or nuisances and to maintain the fertility of the soil. The law is source-oriented (by emission standards) as well as effect-oriented (by ambient air quality standards). To link both elements a two-stage approach is applied. In the first stage preventive measures are taken at the emitting sources, irrespective of existing air pollution levels. Emissions have to be limited by early preventive measures as much as technical and operational conditions allow and as far as economically acceptable (prevention principle). By this, air pollution shall be kept as low as possible as a matter of principle, without the environment having to be in danger first. In a second stage the measures are strengthened or backed up by additional measures if ambient air quality standards laid down in the Ordinance on Air Pollution Control are exceeded. At this second stage, protection of man and his environment has priority over economic considerations. (author)

    Context The last decade witnessed growing differences in abortion dynamics in Belarus, Russia, and Ukraine despite demographic, social, and historical similarities of these nations. This paper investigates changes in birth control practices in the three countries and searches for an explanation of the diverging trends in abortion. Methods Official abortion and contraceptive use statistics, provided by national statistical agencies, were analysed. Respective laws and other legal documents were examined and compared between the three countries. To disclose inter-country differences in prevalence of the modern methods of contraception and its association with major demographic and social factors, an analysis of data from national sample surveys was performed, including binary logistic regression. Results The growing gap in abortion rate in Belarus, Russia, and Ukraine is a genuine phenomenon, not a statistical artefact. The examination of abortion and prevalence of contraception based on official statistics and three national sample surveys did not reveal any unambiguous factors that could explain differences in abortion dynamics in Belarus, Russia, and Ukraine. However, it is very likely that the cause of the inter-country discrepancies lies in contraceptive behavior itself, in adequacies of contraceptive knowledge and practices. Additionally, large differences in government policies, which are very important in shaping contraceptive practices of the population, were detected. Conclusion Since the end of the 1990s, the Russian government switched to archaic ideology in the area of reproductive health and family planning and neglects evidence-based arguments. Such an extreme turn in the governmental position is not observed in Belarus or Ukraine. This is an important factor contributing to the slowdown in the decrease of abortion rates in Russia.

To disclose inter-country differences in prevalence of the modern methods of contraception and its association with major demographic and social factors, an analysis of data from national sample surveys was performed, including binary logistic regression. RESULTS: The growing gap in abortion rate in Belarus, Russia, and Ukraine is a genuine phenomenon, not a statistical artefact. The examination of abortion and prevalence of contraception based on official statistics and three national sample surveys did not reveal any unambiguous factors that could explain differences in abortion dynamics in Belarus, Russia, and Ukraine. However, it is very likely that the cause of the inter-country discrepancies lies in contraceptive behavior itself, in adequacies of contraceptive knowledge and practices. Additionally, large differences in government policies, which are very important in shaping contraceptive practices of the population, were detected. CONCLUSION: Since the end of the 1990s, the Russian government switched to archaic ideology in the area of reproductive health and family planning and neglects evidence-based arguments. Such an extreme turn in the governmental position is not observed in Belarus or Ukraine. This is an important factor contributing to the slowdown in the decrease of abortion rates in Russia.

    Full Text Available Background: Infant mortality is considered as the key healthcare index in every country. The outcomes of a preterm birth are among the main and direct causes of neonate mortality. Therefore, the present research aims to investigate some maternal factors influencing the immature birth. Materials and Methods: This observational case study was conducted on 100 term babies as the control group. The questionnaires were completed through interviewed mothers or perused hospital files. Results: The results of this study showed the high chances of premature birth in women with multiple pregnancies, smoking, placenta previa, uterine problems and placental abruption compared to most of the mothers with no history of such problems. In mothers with cervical incompetence, the chances of delivering a preterm baby are 11 times as high as mothers with no such problems. Similarly, the chances are 9.33 times as high among the mothers who had a history of placenta previa. Conclusion: Identifying maternal factors influencing the preterm infant birth as well as attentive care taken during pregnancy can significantly reduce the preterm infant birth.

    The current worldwide pandemic of antibiotic resistance shows no signs of abating. It is clear that it is driven mainly by heavy and often inappropriate antibiotic use. Although control measures are widely practised, it is important that we assess their efficacy critically in order to concentrate expensive control efforts where they will be most effective. The past year has seen much activity in this area, with evidence-based assessments of the literature according to strict guidelines, as well as progress in basic science studies of mechanisms of resistance, and their causes and relations to pathogenicity and adaptability. The present review summarizes current developments in the causes of antibiotic resistance, the classification of antibiotic stewardship and control measures, the evidence base for their efficacy, current problems in hospital practice, the adaptability of bacteria, the content of antibiotic policies and anticipated activities. The conclusions from the published literature are that much of it that pertains to changing prescribing practices does not stand up to modern evidence-based analysis concepts. Nevertheless, we can learn from experience in changing other areas of medical practice. We must be pragmatic and must not expect to change the world, but rather take it step by step, recognizing barriers and measuring outcomes and quality indicators. Studies into the molecular basis of resistance confirm the superb genetic adaptability of micro-organisms. They will always be several steps ahead of us. Nevertheless, we are learning how to modify our prescribing habits to minimize resistance, not only by using antibiotics less frequently but also by altering dosing schedules in various ways.

    Full Text Available Normally, chemical pesticides kill not only pests but also their natural enemies. In order to better control the pests, two-time delayed stage-structured predator-prey models with birth pulse and pest control tactics are proposed and analyzed by using impulsive differential equations in present work. The stability threshold conditions for the mature prey-eradication periodic solutions of two models are derived, respectively. The effects of key parameters including killing efficiency rate, pulse period, the maximum birth effort per unit of time of natural enemy, and maturation time of prey on the threshold values are discussed in more detail. By comparing the two threshold values of mature prey-extinction, we provide the fact that the second control tactic is more effective than the first control method.

    Prenatal multiple micronutrient (MMN) or balanced energy and protein supplementation has a limited effect on birth size of the offspring. The objective was to determine whether a prenatal MMN-fortified food supplement (FFS) improves anthropometric measures at birth compared with supplementation with an MMN pill alone. We conducted a nonblinded, individually randomized controlled trial in 1296 pregnant women in 2 villages in rural Burkina Faso. Supplements were provided on a daily basis, and compliance was closely verified by using a community-based network of home visitors. Anthropometric measures at birth were available for analysis for 87% of the 1175 live singleton deliveries enrolled. After adjustment for gestational age at birth, the FFS group had a significantly higher birth length (+4.6 mm; P = 0.001). FFS supplementation resulted in a modestly higher birth weight (+31 g; P = 0.197). Subgroup analyses showed clinically important treatment effects on birth length (+12.0 mm; P = 0.005) and on birth weight (+111 g; P = 0.133) for underweight [body mass index (in kg/m(2)) birth to longer newborns (+7.3 mm; P = 0.002) than did those who received MMN supplementation. The provision of FFS to pregnant women resulted in higher birth length than did MMN supplementation. For women with a suboptimal prepregnancy nutritional status, MMN supplementation should be complemented with a balanced energy and protein supplement to produce a clinical effect on birth size. The trial was registered at clinicaltrials.gov as NCT00909974.

    Family-policy regimes unfavourable to combining employment with motherhood have been claimed to increase socio-economic differentials in fertility as combining employment and motherhood has become more normative. This claim has to date been explored mainly in reference to ‘liberal’ Anglo-American regimes. Comparing education differentials in age at first birth among native-born women of 1950s and 1960s birth cohorts in seven countries representing three regime types, we find persistence in early first births among low-educated women not only in Britain and the United States but also in Greece, Italy, and Spain. Shifts towards later first births, however, were more extreme in Southern Europe and involved to some extent women at all education levels. The educationally-heterogeneous changes in age patterns of first births seen in the Southern European and Anglo-American family-policy regimes contrast with educationally-homogeneous changes across birth cohorts seen in the study’s two ‘universalistic’ countries, Norway and France.

    2015-01-01

    Mexico's indigenous regions are characterised by socio-economic marginalisation and poor health outcomes and the Maternal Mortality Rate in indigenous communities continues to be around six times higher than the national rate. Using as a case study the Huichol community of North-Western Mexico we will discuss how institutional health and welfare programmes which aim to address accepted risk factors for maternal health are undermined by a series of structural barriers which put indigenous women especially in harm's way. Semi-structured interviews and observational data were gathered between 2009 and 2011 in highland communities and on coastal tobacco plantations to where a large number of this ethnic group migrate. Many Huichol women birth alone, and to facilitate this process they maintain a low nutritional intake to reduce their infant's growth and seek spiritual guidance during pregnancy from a shaman. These practices are reinforced by feelings of shame and humiliation encountered when using institutional health provision. These are some of the structural barriers to care that need to be addressed. Effective interventions could include addressing the training of health professionals, focusing on educational inequalities and the structural determinants of poverty whilst designing locally specific programmes that encourage acceptance of available health care.

    Full Text Available Background and Objective: Preterm birth (PTB is an important issue in public health and is a major cause for infant mortality and morbidity. There is a growing consensus that systemic diseases elsewhere in the body may influence PTB. Recent studies have hypothesized that maternal periodontitis could be a high-risk factor for PTB. The aim of the present study was to investigate the relationship between maternal periodontitis on PTB. Materials and Methods: Forty systemically healthy primiparous mothers aged 18–35 years were recruited for the study. Based on inclusion and exclusion criteria, they were categorized into PTB group as cases and full term birth group (FTB as controls. PTB cases (n = 20 defined as spontaneous delivery before/<37 completed weeks of gestation. Controls (FTB were normal births at or after 37 weeks of gestation. Data on periodontal status, pregnancy outcome variables, and information on other factors that may influence adverse pregnancy outcomes were collected within 2 days of labor. Data were subjected to Student's t-test and Pearson's correlation coefficient statistical analysis. Results: Statistically significant difference with respect to the gestational period at the time of delivery and birth weight of the infants in (PTB group (<0.001 compared to (FTB group was observed. Overall, there was statistically significant poor periodontal status in the (PTB group compared to (FTB group. The statistical results also showed a positive correlation between gestational age and clinical parameters. Conclusion: An observable relationship was noticed between periodontitis and gestational age, and a positive correlation was found with respect to PTB and periodontitis. Further studies should be designed to establish periodontal disease as an independent risk factor for PTB/preterm low birth weight.

    Full Text Available Abstract Background The aim of this study was first, to investigate whether women starting oral contraceptive (OC use at a young age and before first birth have an increased risk for breast cancer and second, to report difficulties encountered in studying long-term health impacts of medical technologies. Methods Breast cancers occurring up until 1997 among 37153 Helsinki students born between 1946 and 1960 were identified by record linkage from the Finnish Cancer Registry; for each cancer case, five age-matched random controls were picked from the same student population. Those who had used the Helsinki Student Health Service (HSHS at least three times (150 cases and 316 controls form the final study subjects. Data on OC use and background characteristics were collected from patient records, and data on live births were derived from the population register. Odds ratios (OR were adjusted for number of births, smoking and sports activity. Results Compared to the few non-users, OC users had a higher risk of breast cancer: the adjusted OR was 2.1 (95% confidence interval 1.1–4.2. Among OC users, no statistically significant differences in risk of breast cancer were found in regard to starting age or first birth, but small numbers made confidence intervals wide. Even though we had chosen students to be our study group, the population turned out to be unsuitable to answer our research question: most women had started their OC use old (at the age of 20 or later and there were very few unexposed (almost all had used OC and before their first birth. Conclusions Because adoption of the modern pattern of OC use was not common among students, it is unlikely that the impact of early and extended OC use can be studied before 2010, when women born in the 1960s are 40 to 50 years old.

    The authors outline a marketing approach for family planning programs in developing countries, with references to experiences in India. Following an overview of types of population programs, suggestions for strengthening program efforts are offered, and a framework for marketing birth control is described. "This approach was based on the recognition that acceptance of a small family norm is interwoven with the freedom to make that choice.... This framework suggests that marketing plans should be aimed at the three-dimensional goal of increasing the population's desire, ability, and capability toward acceptance of the small family norm and the practice of birth control [and] that in consideration of the wide geographical variations in population growth, per capita income, and the level of development in general, programs should be designed in a segmented manner to suit the socio-economic nature of each group." excerpt

    There is little information on the extent to which African countries are addressing alcohol consumption and alcohol-related harm, which suggests that evaluations of national alcohol policies are needed in this region. The aim of this article is to examine the strength of a mix of national alcohol control policies in African countries, as well as the relationship between alcohol policy restrictiveness scores and adult alcohol per capita consumption (APC) among drinkers at the national level. We examined national alcohol policies of 46 African countries, as of 2012, in four regulatory categories (price, availability, marketing and drink-driving), and analyzed the restrictiveness of national alcohol policies using an adapted Alcohol Policy Index (API). To assess the validity of the policy restrictiveness scores, we conducted correlational analyses between policy restrictiveness scores and APC among drinkers in 40 countries. Countries attained a mean score of 44.1 of 100 points possible, ranging from 9.1 (Sao Tomé and Principe) to 75.0 (Algeria), with low scores indicating low policy restrictiveness. Policy restrictiveness scores were negatively correlated with and APC among drinkers (rs = -0.353, P = 0.005). There is great variation in the strength of alcohol control policies in countries throughout the African region. Tools for comparing the restrictiveness of alcohol policies across countries are available and are an important instrument to monitor alcohol policy developments. The negative correlation between policy restrictiveness and alcohol consumption among drinkers suggests the need for stronger alcohol policies as well as increased training and capacity building at the country level. © The Author 2015.

    The Health and Environmental Sciences Institute (HESI) Developmental and Reproductive Toxicology Technical Committee sponsored a pharmaceutical industry survey on current industry practices for contraception use during clinical trials. The objectives of the survey were to improve our understanding of the current industry practices for contraception requirements in clinical trials, the governance processes set up to promote consistency and/or compliance with contraception requirements, and the effectiveness of current contraception practices in preventing pregnancies during clinical trials. Opportunities for improvements in current practices were also considered. The survey results from 12 pharmaceutical companies identified significant variability among companies with regard to contraception practices and governance during clinical trials. This variability was due primarily to differences in definitions, areas of scientific uncertainty or misunderstanding, and differences in company approaches to enrollment in clinical trials. The survey also revealed that few companies collected data in a manner that would allow a retrospective understanding of the reasons for failure of birth control during clinical trials. In this article, suggestions are made for topics where regulatory guidance or scientific publications could facilitate best practice. These include provisions for a pragmatic definition of women of childbearing potential, guidance on how animal data can influence the requirements for male and female birth control, evidence-based guidance on birth control and pregnancy testing regimes suitable for low- and high-risk situations, plus practical methods to ascertain the risk of drug-drug interactions with hormonal contraceptives.

This study sought to characterize the use of Birth Control methods by women users of Healthcare Service Provider Institutions in Colombia, who were included in the National Health Survey -2007 NHS. Methodology. Ours was a descriptive study, which performed secondary analysis of the data from a subsample of 2033 women from the outpatient service of the Birth Control (BC program in the Healthcare Service Provider Institutions (IPS, for the term in Spanish included in the 2007 National Health Survey (NHS. Results. The BC contraception methods most used by the women surveyed were: hormonal (60%, barrier (22%, and female sterilization (11%. A direct relationship was observed between educational level and the autonomy to select the BC method. A total of 11% of the users did not receive information on all the BC methods from their treating physician. Some 98% of the women surveyed manifested having understood the information provided on the use of the BC method selected. Nine of every 10 women exercised autonomy upon selecting a BC method. Conclusion. The hormonal methods of Birth Control were the most used by the women surveyed. The participants showed high autonomy to choose the BC method.

    Pregnancy- and birth-related factors may have an effect on handedness. Compared with singletons, twins have a lower birth weight, shorter gestational age, and are at higher risk for birth complications. We tested whether the prevalence of left-handedness is higher among twins than singletons, and if so, whether that difference is fully explained by pregnancy and birth-related differences between twins and singletons. We analyzed Finnish population-based datasets; included were 8,786 twins and 5,892 singletons with information on birth weight (n = 12,381), Apgar scores (n = 11,129), and gestational age (n = 11,811). Two twin cohorts were involved: FinnTwin12 included twins born during 1983-1987, and FinnTwin16 included twins born during 1974-1979. We had two comparison groups of singletons: 4,101 individuals born during 1986-1988 and enrolled in the Helsinki Ultrasound Trial, and 1,791 individuals who were partners of FinnTwin16 twins. We used logistic regression models with writing hand as the outcome for comparison and evaluating effects of covariates. Left-handedness was more common in twins (9.67%) than in singletons (8.27%; p = .004). However, Apgar scores were associated with handedness, and after controlling for covariates, we found no difference in the prevalence of left-handedness between twins and singletons. Increased left-handedness among twins, often reported by others, was evident in our data, but only among our older twin cohorts, and that association disappeared after removing effects of perinatal covariates.

    Air pollution is one of the most serious environmental problems, and it is also the inevitable result of the extensive economic development mode. The matter of air pollution in Beijing is becoming more and more serious since 2010, which has a great impact on the normal social production, living and human health. These hazards have been highly valued by the whole society. More than 30 years have been pasted since controlling the air pollution and the system of policies was relatively complete. These policies have improved the quality of atmospheric and prevented environment further deterioration. The policies performance is not obvious. It is urgent trouble to improve policy performance. This paper analyzes the 103 policies text of air pollution control in Beijing, and researches status, history and problems, and put forward suggestions on policy improvement and innovation at last.

  13. Tobacco control, global health policy and development: towards policy coherence in global governance

    Collin, Jeff

    2015-01-01

    The WHO Framework Convention on Tobacco Control (FCTC) demonstrates the international political will invested in combating the tobacco pandemic and a newfound prominence for tobacco control within the global health agenda. However, major difficulties exist in managing conflicts with foreign and trade policy priorities, and significant obstacles confront efforts to create synergies with development policy and avoid tensions with other health priorities. This paper uses the concept of policy coherence to explore congruence and inconsistencies in objectives, policy, and practice between tobacco control and trade, development and global health priorities. Following the inability of the FCTC negotiations to satisfactorily address the relationship between trade and health, several disputes highlight the challenges posed to tobacco control policies by multilateral and bilateral agreements. While the work of the World Bank has demonstrated the potential contribution of tobacco control to development, the absence of non-communicable diseases from the Millennium Development Goals has limited scope to offer developing countries support for FCTC implementation. Even within international health, tobacco control priorities may be hard to reconcile with other agendas. The paper concludes by discussing the extent to which tobacco control has been pursued via a model of governance very deliberately different from those used in other health issues, in what can be termed ‘tobacco exceptionalism’. The analysis developed here suggests that non-communicable disease (NCD) policies, global health, development and tobacco control would have much to gain from re-examining this presumption of difference.

    Patriarchal traditions and a history of armed conflict in Timor-Leste provide a context that facilitates violence against women. More than a third of ever-married Timorese women report physical and/or sexual domestic violence (DV) perpetrated by their most recent partner. DV violates women's rights and may threaten their reproductive health. Marital control may also limit women's reproductive control and healthcare access. Our study investigated relationships between DV and marital control and subsequent family planning, maternal healthcare, and birth outcomes in Timor-Leste. Using logistic regression, we examined 2009-2010 Demographic and Health Survey data from a nationally representative sample of 2,951 women in Timor-Leste. We controlled for age, education, and wealth. We limited our analyses of pregnancy- and birth-related outcomes to those from the 6 months preceding the survey. Rural women with controlling husbands were less likely than other rural women to have an unmet need for family planning (Adj. OR 0.6; 95 % CI 0.4-0.9). Rural women who experienced DV were more likely than other rural women to have an unplanned pregnancy (Adj. OR 2.6; 95 % CI 1.4-4.8), fewer than four antenatal visits (Adj. OR 2.3; 95 % CI 1.1-4.9), or a baby born smaller than average (Adj. OR 3.1; 95 % CI 1.4-6.7). DV and marital control were not associated with the tested outcomes among urban women. Given high rates of DV internationally, our findings have important implications. Preventing DV may benefit both women and future generations. Furthermore, rural women who experience DV may benefit from targeted interventions that mediate associated risks of negative family planning, maternal healthcare, and birth outcomes.

    The issue of preterm birth due to exposure to magnetic fields from power lines is unclear. Exposure to electromagnetic field in uterus has been hypothesized as possible preterm birth. The aim of the present study was to determine whether living closer to high voltage power lines increased the risk of preterm labor. In a nested case-control study, 135 cases of singleton live spontaneous preterm birth in Rohani hospital, Babol, Iran, during the period between 2013 and 2014 were studied. The 150 control subjects were singleton term live birth in the same year of birth and city of residence using randomized-digit dialing. The shortest distance to any of the high voltage power lines to the maternal residence during pregnancy was measured using ArcGIS software for every case and control. To test the association between the preterm births and the residential proximity to power lines, stepwise multiple logistic regression was used. There were 28 households, 20 cases (14.8%) and 8 controls (5.3%) situated within 600 meters of high voltage power lines. The adjusted OR for spontaneous preterm birth and birth defect in women who were living in less than 600 meters from high voltage power lines was higher compared to those living at farther distance (OR = 3.28, CI: 1.37 to 7.85) and (OR = 5.05, CI: 1.52 to 16.78), respectively. Therefore, installing overhead power lines and stations within 600 meters or making overhead underground would be useful in the prevention of both preterm birth and birth defect.

    To describe the essential features of the newly established Murmansk County Birth Registry (MCBR); make some preliminary comparisons of selected variables related to pregnancy and delivery in northern counties of the Nordic countries and in cities and towns of Murmansk County [Murmanskaja Oblast (MO)] and explore some research possibilities. A registry-based cohort study. The MCBR was established in 2005 and registration began on 1 January 2006. A registry form draws upon both hospital files and information from the mother. There are 54 major fields consisting primarily of tick-off boxes and International Classification of Diseases (ICD-10) codes. A quality control exercise was conducted in both 2006 and 2007. During 2006, 8,468 births were registered in the MO (coverage = 98.9%). The proportion of errors was below 1% in both years. Limiting the descriptive statistics to 2006, compared to counties of the Nordic counties in the Barents Region, the delivering women in the MO were younger and had fewer and lighter (mean of 200 g) babies. The gestational age was somewhat shorter in the MO than in the Nordic counties and fewer babies had a birthweight above 4,500 g. The perinatal mortality corresponding to a gestational age (GA) of either 22 or 28 completed weeks was higher (p < 0.02) in the MO than the Nordic counties in this study. In the MO, the birth rate does not balance the reported increase in death rate. Our study concludes that a medical birth registry of satisfactory quality has been established for the world's largest arctic population.

    Clinical practice guidelines indicate that over 80% of women with a previous caesarean should be offered a planned vaginal birth after caesarean (VBAC), however only one third of eligible women choose to plan a VBAC. To support informed choices for birth after caesarean, it is necessary to understand the factors that influence women's decision-making. The goal of this study was to explore attitudes towards and experiences with decision-making for mode of delivery after caesarean from the perspectives of Canadian women. In-depth, semi-structured interviews were conducted with 23 women eligible for VBAC in three rural and two urban communities in British Columbia, Canada, during summer 2015. Constructivist grounded theory informed iterative data collection and analysis. Women's decision-making experiences were a process of "seeking control in the midst of uncertainty." Women formed early preferences for mode of delivery after their primary caesareans and engaged in careful deliberation during their inter-pregnancy interval, consisting of: reflecting on their birth, clarifying their values, becoming informed, considering the feasibility of options, deliberating with the care team, and making an actual choice. Women struggled to make trade-offs between having a healthy baby and social attributes of delivery, such as uninterrupted bonding with their newborn. Women begin decision-making for birth after caesarean earlier than previously reported and their choices are influenced by personal experience and psychosocial concerns. Future interventions to support choice of mode of delivery should begin early after the primary caesarean, to reflect when women begin to form preferences.

  20. Women Bar Drinkers’ Discussions about Birth Control and Risky Sexual Behavior

    This study evaluated how birth control discussions prior to sexual activity affected condom use in a sample of 225 young women bar drinkers. The use of alcohol and other drugs (AOD) and partner type also were assessed. Data were collected through daily reports and qualitative interviews over 12 weeks. A total of 1671 sexual events were reported (M = 7.4 events per participant), of which 64.7% (n = 1081) did not involve condom use. Discussions of birth control occurred prior to 10.9% (n = 183) of all sexual events. These discussions were more likely to be initiated by the woman and to occur when AOD had been used. Thematic analysis revealed four common themes: confirmation of the need to use condoms, confirmation of oral/hormonal contraceptive use, use of sufficient birth control, and discrepant condom use. The discussions reduced rates of risky sex when the sexual partner was more intimate (i.e., boyfriend/dating partner), regardless of AOD use and when the sexual partner was a friend or ex-partner and no AOD were used. The thematic analysis suggested that pregnancy prevention was a stronger motivation for discussing condom use, rather than risk of contracting an STI. Given the substantial rate of high risk partners, history of STIs, and limited amount of time women reported knowing “regular” partners, we suggest that interventions designed to reduce risky sex should be tailored to increase women’s awareness of STI and pregnancy risk when under the influence of AOD, and promote condom use regardless of partner type.

  1. Breastfeeding is associated with a maternal feeding style low in control from birth.

    Full Text Available The influence of maternal child-feeding style upon child weight and eating style for children over the age of twelve months is well established. However there is little empirical evidence examining maternal child-feeding style during milk feeding despite evidence that mothers who breastfeed exert lower levels of control over later diet. The aim of this paper was to examine variation in maternal child-feeding style during the first six months postpartum and to explore associations with mode of milk feeding and infant weight.The Child Feeding Questionnaire (CFQ is frequently used to measure maternal child-feeding style in preschool children. 390 mothers with an infant aged 0-6 months completed an adapted version of the CFQ to measure maternal child-feeding style during milk feeding. Participants reported breastfeeding duration, infant weight and perceived size.Principle components analysis of questionnaire items produced six factors; encouraging feeding, feeding to a routine, limiting intake, concern for weight, monitoring and perceived responsibility. Breastfeeding was associated with lower levels of control compared to formula feeding. Infant birth weight was significantly inversely associated with concern for weight, monitoring and encouraging feeding.Formula feeding is associated with greater maternal control of child-feeding from birth whilst a lower birth weight is linked to concerns for infant weight and pressure to eat. As early maternal child-feeding relationships may impact negatively upon longer term child weight and eating style, identifying variations in maternal feeding style and understanding the factors that influence this is pertinent.

    Stormwater source control is becoming a common strategy for urban stormwater management in many countries. It relies on regulations or other policy instruments compelling or inciting implementation, for each new urban development, of small-scale facilities to locally store and manage stormwater. Local authorities that pioneered source control since the 1980s have already observed that small-scale facilities systematically implemented over a catchment are able to influence its hydrological behaviour. This capability is the main strength of source control, as it allows compensation for the negative effects of urbanization. Yet, it also represents its main risk: if initial decision-making is not sufficiently accurate, source control can produce long-term negative effects. Because of its current spreading, source control will acquire an increasing role as a driver of hydrological changes in urban catchments, and the directions of these changes depend on current policy-making practices. This paper presents an analysis and a critical discussion of the main objectives that policy-makers attribute to stormwater source control. The investigation is based on a sample of French case studies, completed by a literature review for international comparison. It identifies four main objectives, some typical of urban stormwater management and some more innovative: flood reduction, receiving waters protection, sustainable development, costs reduction. The discussion focuses on how current policy-making practices are able to translate these objectives in concrete policy instruments, and on which knowledge and tools could improve this process. It is shown that for some objectives, basic knowledge is available, but the creation of policy instruments which are effective at the catchment scale and adapted to local conditions is still problematic. For other objectives, substantial lacks of knowledge exist, casting doubts on long-term effectiveness of current policy instruments. Research

    Early adolescent pregnancy presents a major barrier to the health and wellbeing of young women and their children. Previous studies suggest geographic heterogeneity in adolescent births, with clear "hot spots" experiencing very high prevalence of teenage pregnancy. As the reduction of adolescent pregnancy is a priority in many countries, further detailed information of the geographical areas where they most commonly occur is of value to national and district level policy makers. The aim of this study is to develop a comprehensive assessment of the geographical distribution of adolescent first births in Uganda, Kenya and Tanzania using Demographic and Household (DHS) data using descriptive, spatial analysis and spatial modelling methods. The most recent Demographic and Health Surveys (DHS) among women aged 20 to 29 in Tanzania, Kenya, and Uganda were utilised. Analyses were carried out on first births occurring before the age of 20 years, but were disaggregated in to three age groups: poverty. There is marked geographic heterogeneity in the prevalence of adolescent first births in East Africa, particularly in the youngest age groups. Geospatial techniques can identify these inequalities and provide policy-makers with the information needed to target areas of high prevalence and focus scarce resources where they are most needed.

    Thallium (Tl) is a highly toxic heavy metal widely present in the environment. Case reports have suggested that maternal exposure to high levels of Tl during pregnancy is associated with low birth weight (LBW), but epidemiological data are limited. This study was designed to evaluate whether prenatal Tl exposure is associated with an increased risk of LBW. This case-control study involving 816 study participants (204 LBW cases and 612 matched controls) was conducted in Hubei Province, China, in 2012-2014. Tl concentrations were measured in maternal urine collected at delivery, and associations with LBW were evaluated using conditional logistic regression. Higher maternal urinary Tl levels were significantly associated with increased risk of LBW [crude odds ratio (OR) = 1.52; 95% CI: 1.00, 2.30 for the highest vs. lowest tertile], and the association was similarly elevated after adjustment for potential confounders (adjusted OR = 1.90; 95% CI: 1.01, 3.58 for the highest vs. lowest tertile). Stratified analyses showed slightly higher risk estimates for LBW associated with higher Tl levels for mothers thallium exposure and low birth weight in China.

    During 20-22 September Manchester is to host the 1993 follow up to last year's "earth summit" in Rio de Janeiro. At that summit the threat posed by world overpopulation received considerable attention. Catholicism was perceived as opposed to birth control and therefore as a particular threat. This was based on the notion that the only method of birth control approved by the church--natural family planning--is unreliable, unacceptable, and ineffective. In the 20 years since E L Billings and colleagues first described the cervical mucus symptoms associated with ovulation natural family planning has incorporated these symptoms and advanced considerably. Ultrasonography shows that the symptoms identify ovulation precisely. According to the World Health Organisation, 93% of women everywhere can identify the symptoms, which distinguish adequately between the fertile and infertile phases of the menstrual cycle. Most pregnancies during trials of natural family planning occur after intercourse at times recognised by couples as fertile. Thus pregnancy rates have depended on the motivation of couples. Increasingly studies show that rates equivalent to those with other contraceptive methods are readily achieved in the developed and developing worlds. Indeed, a study of 19,843 poor women in India had a pregnancy rate approaching zero. Natural family planning is cheap, effective, without side effects, and may be particularly acceptable to the efficacious among people in areas of poverty.

    With China's significant role on pollution emissions and related health damage, deep and up-to-date understanding of China's air pollution policies is of worldwide relevance. Based on scientific evidence for the evolution of air pollution and the institutional background of environmental governance in China, we examine the development of air pollution control policies from the 1980s and onwards. We show that: (1) The early policies, until 2005, were ineffective at reducing emissions; (2) During 2006-2012, new instruments which interact with political incentives were introduced in the 11th Five-Year Plan, and the national goal of reducing total sulfur dioxide (SO₂) emissions by 10% was achieved. However, regional compound air pollution problems dominated by fine particulate matter (PM 2.5 ) and ground level ozone (O₃) emerged and worsened; (3) After the winter-long PM 2.5 episode in eastern China in 2013, air pollution control policies have been experiencing significant changes on multiple fronts. In this work we analyze the different policy changes, the drivers of changes and key factors influencing the effectiveness of policies in these three stages. Lessons derived from the policy evolution have implications for future studies, as well as further reforming the management scheme towards air quality and health risk oriented directions.

    Full Text Available Birth weight of a child is an important indicator of its vulnerability for childhood illness and chances of survival. A large number of infant deaths can be averted by appropriate management of low birth weight babies and prevention of factors associated with low birth weight. The prevalence of low birth weight babies in Nepal is estimated to be about 12-32%.Our study aimed at identifying major determinants of low birth weight among term babies in Nepal. A hospital-based retrospective case control study was conducted in maternity ward of Tribhuvan University Teaching Hospital from February to July 2011. A total of 155 LBW babies and 310 controls were included in the study. Mothers admitted to maternity ward during the study period were interviewed, medical records were assessed and anthropometric measurements were done. Risk factors, broadly classified into proximal and distal factors, were assessed for any association with birth of low-birth weight babies. Regression analysis revealed that a history of premature delivery (adjusted odds ratio; aOR5.24, CI 1.05-26.28, hard physical work during pregnancy (aOR1.48, CI 0.97-2.26, younger age of mother (aOR1.98, CI 1.15-3.41, mothers with haemoglobin level less than 11gm/dl (aOR0.51, CI0.24-1.07 and lack of consumption of nutritious food during pregnancy (aOR1.99, CI 1.28-3.10 were significantly associated with the birth of LBW babies. These factors should be addressed with appropriate measures so as to decrease the prevalence of low birth weight among term babies in Nepal.

    2016-10-01

    Evidence from various epidemiological studies and experimental animal studies has linked adverse intrauterine circumstances with health problems in adult life. This field of investigation is known as Developmental Origins of Health and Disease (DOHaD). Studies investigating the relation between developing polycystic ovary syndrome (PCOS) in adulthood and birth weight have yielded inconsistent results: PCOS is described more often in women with low birth weight and high birth weight, while other studies have failed to establish any relation. In this retrospective case-control study, we evaluated whether women diagnosed with PCOS had lower birth weight compared to women with a regular menstrual cycle (controls). Binary logistic regression models were used to analyze the data and correct for known confounders. About 65 women with PCOS and 96 controls were recruited for this purpose. The average birth weight of PCOS women (3357 g) did not differ from the average birth weight of controls (3409 g). Mean age at menarche differed significantly between groups, 13.7  years and 12.8  years (p = 0.006), respectively, for PCOS women and controls. In conclusion, we could not confirm the effect of adverse intrauterine conditions, reflected in birth weight, on developing PCOS.

    To examine how the relaxation of the one child policy and policies to reduce caesarean section rates might have affected trends over time in caesarean section rates and perinatal and pregnancy related mortality in China. Observational study. China's National Maternal Near Miss Surveillance System (NMNMSS). 6 838 582 births at 28 completed weeks or more of gestation or birth weight ≥1000 g in 438 hospitals in the NMNMSS between 2012 and 2016. Obstetric risk was defined using a modified Robson classification. The main outcome measures were changes in parity and age distributions and relative frequency of each Robson group, crude and adjusted trends over time in caesarean section rates within each risk category (using Poisson regression with a robust variance estimator), and trends in perinatal and pregnancy related mortality over time. Caesarean section rates declined steadily between 2012 and 2016 (crude relative risk 0.91, 95% confidence interval 0.89 to 0.93), reaching an overall hospital based rate of 41.1% in 2016. The relaxation of the one child policy was associated with an increase in the proportion of multiparous births (from 34.1% in 2012 to 46.7% in 2016), and births in women with a uterine scar nearly doubled (from 9.8% to 17.7% of all births). Taking account of these changes, the decline in caesarean sections was amplified over time (adjusted relative risk 0.82, 95% confidence interval 0.81 to 0.84). Caesarean sections declined noticeably in nulliparous women (0.75, 0.73 to 0.77) but also declined in multiparous women without a uterine scar (0.65, 0.62 to 0.77). The decrease in caesarean section rates was most pronounced in hospitals with the highest rates in 2012, consistent with the government's policy of targeting hospitals with the highest rates. Perinatal mortality declined from 10.1 to 7.2 per 1000 births over the same period (0.87, 0.83 to 0.91), and there was no change in pregnancy related mortality over time. China is the only country that

    To improve our understanding of males' role in contraceptive practices, this paper explores the relationship between young males' perspectives on pregnancy and fatherhood and their attitudes, beliefs and practices in relation to condom use and birth control. Semi-structured interviews were conducted with a sample of 42 males aged 15-25 years. A systematic process of thematic analysis was used to reduce and organise the narrative data around the focus areas of relationships, sex, condom use, STIs and pregnancy/fatherhood. To facilitate the emergence of key patterns in the data, new data was constantly compared with existing ideas to formulate and refine codes and descriptive categories. The analysis revealed a clear discrepancy between young males' desire to prevent pregnancy and the level of control they assumed over this. Despite pregnancy emerging as the overriding concern for participants, this failed to motivate continued use of condoms when STI risk was perceived as low and a partner was using birth control. Reliance on a partner's use of hormonal contraceptives and in several cases, beliefs of low personal responsibility for pregnancy prevention reduced young males' participation in fertility control. Young males' unfavourable attitudes toward immediate pregnancy and fatherhood provide a unique opportunity for safe sex promotion by encouraging greater ownership over sexual and reproductive health outcomes. However, this requires a shift in the meanings associated with condoms, from a disease prevention only orientation to one that promotes condom use as a positive act for self and partner protection.

  4. The right to have a family: 'legal trafficking of children', adoption and birth control in Brazil.

    2012-01-01

    This paper focuses on one of the 'child-trafficking scandals' that occurred in Brazil in the 1990s. Ethnographic research was carried out between 2000 and 2001 within a movement of poor families formed in São Paulo to put pressure on the authorities to review the legal procedures that had led to their children being placed for national and international adoption. Fieldwork was supplemented by other data, including reports by legislative bodies, articles in the press, and case files involving the termination of parental rights. This paper explores views on international adoption among members of the Brazilian elites such as judges, agents in the field of child protection and journalists, in the context of old but persistent neo-Malthusian ideas. Although the Brazilian birth rate is now below the replacement level, it is still common to blame 'irresponsible' reproduction among the urban poor for violence in large cities. Drawing a parallel with the routine sterilization of women that prevailed for decades and was encouraged by Brazilian physicians, the paper examines how, in a 'struggle against poverty', judicial agents took it upon themselves to enforce 'birth control' through adoption, bypassing family consent and the law in the process. The paper concludes by arguing that discrimination against poor families who are viewed as disorganized, immoral and irresponsible - characteristics frequently associated with criminality by a sector of the elites - has contributed to the view that lower-class families do not have the right to bear children, or to keep them.

    This paper is aimed at critically assessing the extent to which Non-Communicable Disease NCD-related policies introduced in Bangladesh align with the World Health Organization's (WHO) 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. The authors reviewed all relevant policy documents introduced by the Government of Bangladesh since its independence in 1971. The literature review targeted scientific and grey literature documents involving internet-based search, and expert consultation and snowballing to identify relevant policy documents. Information was extracted from the documents using a specific matrix, mapping each document against the six objectives of the WHO 2013-2020 Action Plan for the Global Strategy for the Prevention and Control of NCDs. A total of 51 documents were identified. Seven (14%) were research and/or surveys, nine were on established policies (17%), while seventeen (33%) were on action programmes. Five (10%) were related to guidelines and thirteen (25%) were strategic planning documents from government and non-government agencies/institutes. The study covered documents produced by the Government of Bangladesh as well as those by quasi-government and non-government organizations irrespective of the extent to which the intended policies were implemented. The policy analysis findings suggest that although the government has initiated many NCD-related policies or programs, they lacked proper planning, implementation and monitoring. Consequently, Bangladesh over the years had little success in effectively addressing the growing burden of non-communicable diseases. It is imperative that future research critically assess the effectiveness of national NCD policies by monitoring their implementation and level of population coverage.

    Intimate partner violence (IPV) is a major problem that could affect reproductive decision making. The aim of this study is to examine the association between IPV and contraceptive use and assess whether the association varies by receipt of prenatal birth control counseling and race/ethnicity. This study analyzed the 2004-2008 national Pregnancy Risk Assessment Monitoring System (PRAMS) that included 193,310 women with live births in the United States. IPV was determined by questions that asked about physical abuse by a current or former partner in the 12 months before or during pregnancy. The outcome was postpartum contraceptive use (yes vs. no). Multiple logistic regression analyses were conducted to assess the influence of experiencing IPV at different periods (preconception IPV, prenatal IPV, both preconception and prenatal IPV, preconception and/or prenatal IPV). Data were stratified to assess differential effects by race/ethnicity and receipt of birth control counseling. Approximately 6.2% of women reported IPV, and 15.5% reported no postpartum contraceptive use. Regardless of the timing of abuse, IPV-exposed women were significantly less likely to report contraceptive use after delivery. This was particularly true for Hispanic women who reported no prenatal birth control counseling and women of all other racial/ethnic groups who received prenatal birth control counseling. IPV victimization adversely affects the use of contraceptive methods following delivery in women with live births. Birth control counseling by health providers may mitigate these effects; however, the quality of counseling needs further investigation. Better integration of violence prevention services and family planning programs is greatly needed. Consistent with national recommendations by the U.S. Preventive Service Task Force, clinicians and public health workers are strongly encouraged to screen for IPV. Health providers should educate women on effective contraceptive options and

    Hypnotherapy is an integrative mind-body technique with therapeutic potential in various health care applications, including labor and birth. Evaluating the efficacy of this modality in controlled studies can be difficult, because of methodologic challenges, such as obtaining adequate sample sizes and standardizing experimental conditions. Women using hypnosis techniques for childbirth in hospital settings may face barriers related to caregiver resistance or institutional policies. The potential anxiolytic and analgesic effects of clinical hypnosis for childbirth merit further study. Nurses caring for women during labor and birth can increase their knowledge and skills with strategies for supporting hypnotherapeutic techniques. © 2014 AWHONN.

    NAPAP is examining a number of potential ways to reduce the precursors (sulfur dioxide and nitrogen oxides) to acid deposition. However, the policies to reduce acid deposition will have other physical, biological and economic effects unrelated to acid deposition. For example, control policies that reduce sulfur dioxide emissions may also increase visibility. The effects of an acid deposition policy that are unrelated to acid deposition are referred to as ''ancillary'' effects. This reserch identifies and characterizes the principle physical and economic ancillary effects associated with acid deposition control and mitigation policies. In this study the ancillary benefits associated with four specific acid deposition policy options were investigated. The four policy options investigated are: (1) flue gas desulfurization, (2) coal blending or switching, (3) reductions in automobile emissions of NO/sub x/, and (4) lake liming. Potential ancillary benefits of each option were identified and characterized. Particular attention was paid to the literature on economic valuation of potential ancillary effects.

    Full Text Available Alcohol consumption causes an estimated 4% of the global disease burden, prompting governments to impose regulations to mitigate the adverse effects of alcohol. To assist public health leaders and policymakers, the authors developed a composite indicator-the Alcohol Policy Index-to gauge the strength of a country's alcohol control policies.The Index generates a score based on policies from five regulatory domains-physical availability of alcohol, drinking context, alcohol prices, alcohol advertising, and operation of motor vehicles. The Index was applied to the 30 countries that compose the Organization for Economic Cooperation and Development and regression analysis was used to examine the relationship between policy score and per capita alcohol consumption. Countries attained a median score of 42.4 of a possible 100 points, ranging from 14.5 (Luxembourg to 67.3 (Norway. The analysis revealed a strong negative correlation between score and consumption (r = -0.57; p = 0.001: a 10-point increase in the score was associated with a one-liter decrease in absolute alcohol consumption per person per year (95% confidence interval, 0.4-1.5 l. A sensitivity analysis demonstrated the robustness of the Index by showing that countries' scores and ranks remained relatively stable in response to variations in methodological assumptions.The strength of alcohol control policies, as estimated by the Alcohol Policy Index, varied widely among 30 countries located in Europe, Asia, North America, and Australia. The study revealed a clear inverse relationship between policy strength and alcohol consumption. The Index provides a straightforward tool for facilitating international comparisons. In addition, it can help policymakers review and strengthen existing regulations aimed at minimizing alcohol-related harm and estimate the likely impact of policy changes.

    Full Text Available Objective: Identification of variables that affect the risk of severe intraventricular hemorrhage (IVH in very low birth weight (VLBW newborns. Methods: Analytic case-control study, in a population consisting of all VLBW newborns admitted to the Neonatal Intensive Care Unit of a maternity hospital, between January 2002 and December 2007. The authors considered as cases all VLBW newborns with severe IVH (grade ≥ 3, and control all VLBW newborns without IVH. Independent variables included obstetric, perinatal and neonatal diagnosis and therapy. Bivariate analysis and multivariate logistic regression analysis were performed. Rresults: During this period, of the 864 VLBW newborns admitted to the Neonatal Intensive Care Unit, 9.7% had severe IVH. With bivariate analysis an association between severe IVH, gestational age and birth weight was found. Prenatal care and pre-eclampsia were associated with a decrease in the incidence of severe IVH. Amnionitis, being outborn, vaginal delivery, male gender, intubation in the delivery room, surfactant, hyaline membrane disease, pneumothorax, necrotizing enterocolitis (NEC perforation and oscillatory high frequency ventilation were associated with an increased incidence of severe IVH. By multivariate logistic regression, the variables associated with increased risk of severe IVH were: pneumothorax (OR = 3.8; 95%CI = 1.7-8.3, NEC with perforation (OR = 8.8; 95%CI = 1.7-45.0, vaginal delivery (OR = 2.0; 95%CI = 1.0-4.1 and high frequency ventilation (OR = 4.8; 95%CI = 1.3-17.3. The following were protective of severe IVH: gestational age (OR = 0.61; 95%CI = 0.52-0.72, patent ductus arteriosus treatment with indomethacin (OR = 0.26; 95%CI = 0.11-0.6 and fertility treatment (OR = 0.24; 95%CI = 0.06-0.94. Cconclusion: These data outline the importance of improvement of pre and neonatal care to reduce severe IVH.

    Although China's family planning programme is often referred to in the singular, most notably the One-Child policy, in reality there have been a number of different policies in place simultaneously, targeted at different sub-populations characterized by region and socioeconomic conditions. This study attempted to systematically assess the differential impact of China's family planning programmes over the past 40 years. The contribution of Parity Progression Ratios to fertility change among different sub-populations exposed to various family planning policies over time was assessed. Cross-sectional birth history data from six consecutive rounds of nationally representative population and family planning surveys from the early 1970s until the mid-2000s were used, covering all geographical regions of China. Four sub-populations exposed to differential family planning regimes were identified. The analyses provide compelling evidence of the influential role of family planning policies in reducing higher Parity Progression Ratios across different sub-populations, particularly in urban China where fertility dropped to replacement level even before the implementation of the One-Child policy. The prevailing socioeconomic conditions in turn have been instrumental in adapting and accelerating family planning policy responses to reducing fertility levels across China.

    Alcohol-related problems such as assaults and drinking-driving at or near professional sporting events are commonly reported in the media. An important strategy to reduce such problems may be the use of alcohol control policies at sports stadiums. The objective of this study was to examine alcohol control policies and practices at professional sports stadiums in the U.S. We conducted a telephone survey of food/beverage managers from 66 of the 100 U.S professional sports stadiums that house a professional hockey, basketball, baseball, and/or football team. The survey consisted of 18 items pertaining to policies regulating alcohol sales and consumption. Most managers indicated that their stadium had a range of alcohol control policies and practices. For example, all or nearly all reported their stadium allows no more than two alcoholic beverages per sale and their alcohol servers are required to check age identification of patrons who appear younger than age 30. In contrast, only about half prohibit servers younger than 21 years of age from selling alcohol both in seating areas and at concession booths, and approximately one-third designate sections of their stadiums as alcohol-free. Although we found that some alcohol control policies appear to be common across stadiums, others are uncommon, leaving room for potential areas of improvement in reducing or preventing alcohol-related problems at professional sporting events. The results provide an important starting point for identifying policies that can be evaluated to determine their effectiveness in reducing alcohol-related injuries and deaths at sporting events.

    In general, epidemiological studies have evaluated cases with congenital cardiovascular abnormalities together. The aim of this study is to describe the birth outcomes of cases with isolated/single atrial septal defect type II (ASD-II, i.e. only a fossa ovalis defect) after surgical correction or lethal outcome in the light of maternal sociodemographic data. Comparison of birth outcomes and maternal characteristics of cases with ASD-II and controls without defect. The population-based Hungarian Case-Control Surveillance of Congenital Abnormalities. Hungarian newborn infants with or without ASD-II. Medically recorded birth outcomes, maternal age and birth order were evaluated. Marital and employment status was based on maternal information. The lifestyle factors were analyzed in a subsample of mothers visited at home based on a personal interview with mothers and their close relatives, and the family consensus was accepted. Mean gestational age at delivery and birthweight, rate of preterm birth and low birthweight, maternal age, birth order, marital and employment status. The evaluation of 471 cases with ASD-II and 38,151 controls without any defects showed a female excess in cases with ASD-II, having shorter gestational age and lower mean birthweight, and thus a higher rate of preterm births and low birthweight. Intrauterine growth restriction and shorter gestational age were found in cases with ASD-II, particularly in female children. These factors may have a general developmental process in which there was not closure of the foramen ovale, thus echocardiographic screening of these babies might be of value. © 2012 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2012 Nordic Federation of Societies of Obstetrics and Gynecology.

    It is well known that jitter has an impact on control system performance, and this is often used as an argument for static scheduling policies, e.g. a time triggered architecture. However, it is only completion jitter that seriously disturbs standard linear control algorithms in a way similar...... to the delay inherent in a time triggered architecture. Thus we propose that standard control algorithms are scheduled dynamically, but without preemption. Analysis of this policy is contrasted with a corresponding time triggered architecture and is shown to have better impulse response performance both...... in the deterministic case and under white noise disturbances. The conclusion is that under very reasonable assumptions about robustness of control algorithms,they are insensitive to relase jitter, albeit strongly sensitive to completion jitter, thus priority based scheduling without preemption is may be preferable...

  1. International trade agreements challenge tobacco and alcohol control policies.

    Science.gov (United States)

    Zeigler, Donald W

    2006-11-01

    This report reviews aspects of trade agreements that challenge tobacco and alcohol control policies. Trade agreements reduce barriers, increase competition, lower prices and promote consumption. Conversely, tobacco and alcohol control measures seek to reduce access and consumption, raise prices and restrict advertising and promotion in order to reduce health and social problems. However, under current and pending international agreements, negotiated by trade experts without public health input, governments and corporations may challenge these protections as constraints on trade. Advocates must recognise the inherent conflicts between free trade and public health and work to exclude alcohol and tobacco from trade agreements. The Framework Convention on Tobacco Control has potential to protect tobacco policies and serve as a model for alcohol control.

    This randomized controlled clinical trial was carried out to assess the effect of comprehensive nonsurgical periodontal treatment and strict plaque control performed during pregnancy on the reduction of preterm and/or low birth weight rates (PTLBW). Three hundred and three women were randomly allocated to receive periodontal treatment either during pregnancy (n = 147, test group) or after delivery (n = 156, control group). During pregnancy, the control group received only one session of supragingival scaling and oral hygiene instruction. In contrast, the test group received comprehensive periodontal treatment including multiple sessions of scaling and root planing, oral hygiene instructions, and frequent maintenance visits. At baseline, periodontal inflammation was observed in approximately 50% of sites and attachment loss affected controls, women in the test group had significant reductions in the percentage of sites with plaque (48.5% vs. 10.3%, p control significantly improved periodontal health; however, no reduction of PTLBW rates was observed. Thus, remaining periodontal inflammation posttreatment cannot explain the lack of effect of periodontal treatment on PTLBW. Clinical relevance This study demonstrated that periodontal diseases may be successfully treated during pregnancy. Our results do not support a potential beneficial effect of periodontal treatment on PTLBW.

    In this paper, an impulsive model is discussed for an integrated pest management approach comprising of chemical and mechanical controls. The pesticides and harvesting are used to control the stage-structured pest population. The mature pest give birth to immature pest in pulses at regular intervals. The pest is controlled by spraying chemical pesticides affecting immature as well as mature pest. The harvesting of both immature and mature pest further reduce the pest population. The discrete dynamical system obtained from stroboscopic map is analyzed. The threshold conditions for stability of pest-free state as well as non-trivial period-1 solution is obtained. The effect of pesticide spray timing and harvesting on immature as well as mature pest are shown. Finally, by numerical simulation with MATLAB, the dynamical behaviors of the model is found to be complex. Above the threshold level there is a characteristic sequence of bifurcations leading to chaotic dynamics. Route to chaos is found to be period-doubling. Period halving bifurcations are also observed.

    To examine the effectiveness of a birth ball exercise programme during childbirth by measuring childbirth self-efficacy and childbirth pain. In addition, it tested the mediating effects of childbirth self-efficacy on the relationship between the birth ball exercise programme and childbirth pain. Randomised controlled trial. The study was conducted from December 2008 to November 2009, at two birth units, one at a regional hospital and one at a medical centre, with 600 and 1022 annual births, respectively. One hundred and eighty-eight expectant mothers were recruited (recruitment rate: 47%) and were allocated by block randomisation into the two arms of the study, but only 48 intervention and 39 control group participants completing the trial. The birth ball exercise programme consisted of a 26-page booklet and a 19-minute videotape, with periodic follow-ups during prenatal checks. All members of the experimental group were asked to practise the exercises and positions at home for at least 20 minutes three times a week for a period of 6-8 weeks. Each woman in the experimental group was given a birth ball for use during labour and encouraged every hour to choose the most comfortable positions, movements, and exercises. Both the experimental and control groups received standard nursing and midwifery care from hospital staff nurses in all aspects of pregnancy and childbirth. When cervical dilations were four centimetres and eight centimetres, the women completed demographic and obstetrics information, the Childbirth Self-efficacy Inventory (CBSEI), and the short form of the McGill Pain Questionnaire (SF-MPQ). Our study revealed that birth ball exercises provided statistically significant improvements in childbirth self-efficacy and pain. Specifically, self-efficacy had a 30-40% mediating effect on relationships between birth ball exercises and childbirth pain. Mothers in the experimental group had shorter first-stage labour duration, less epidural analgesia, and fewer

    Representatives back to the Republicans by a majority of more than 40 members (with several races still pending at time of writing) and reduced the Democratic hold in the Senate to a paper-thin majority. Although it remains to be seen how the Republicans will govern once they take control of Congress in January 2011, the incoming House leadership will likely back-peddle on the progress enjoyed in U.S. climate policy since the end of the fossil fuel-happy Bush Administration, because the Republicans campaigned fiercely against 'cap-and-trade' policies and promised to investigate the Obama Administration's recent EPA GHG regulations. Even in the race of such regulatory uncertainty, an overview of recent federal, state and regional approaches to reducing GHG emissions provides an indication of where U.S. climate policy will ultimately be headed once the so-called 'political pendulum' inevitably swings back in the direction of environmentally-responsible leadership.

    Full Text Available The European Respiratory Society is an international medical organisation that brings together physicians, healthcare professionals, scientists and other experts working in respiratory medicine. Its aim is to alleviate suffering from respiratory diseases and promote lung health globally through science, education and advocacy. ERS has since its founding in 1990 demonstrated strong commitment to tobacco control. Through scientific assemblies, education courses, various alliances and collaboration (Framework Convention Alliance, European Chronic Disease Alliance, World Health Organisation etc. As well as a Tobacco Control Committee (TCC dedicated to advocacy, ERS constantly strives to promote strong and evidence-based policies to reduce the burden of tobacco related diseases. One of the main outcome of the TCC is the creation of Smokehaz, a website aimed at providing policy-makers with scientific information on the Health hazards associated with smoking. Recently, ERS created the Latin-America Working Group which aims at strengthening tobacco control activities in Spain, Portugal and Latin-American countries.

    Despite progress in policy changes, tobacco use rates are still high in the military. Little is known about the views of those who create and implement tobacco control policies within the Department of Defense. These individuals determine what policy initiatives will be developed, prioritized, and implemented. We conducted key informant interviews with 16 service-level policy leaders (PLs) and 36 installation-level tobacco control managers (TCMs). PLs and TCMs believed that line leadership view tobacco control as a low priority that has minimal impact on successful mission completion. They also identified cultural factors that perpetuate tobacco use, such as low cost and easy accessibility to tobacco, smoke breaks, and uneven or unknown enforcement of current tobacco policies.

    A woman's psychological health can affect prenatal behaviors. The purpose of this study was to examine the relationship between maternal beliefs, prenatal behaviors, and preterm birth (PTB) in a multiethnic population. This was a planned secondary analysis of a cross-sectional trial of postpartum women with singleton gestation. In all, 210 participants were given the Fetal Health Locus of Control (FHLC) scale to measure three primary maternal beliefs that influenced their prenatal behaviors (Internal Control, Chance, Powerful Others). Women who experienced preterm delivery and those who smoked during pregnancy scored the Chance category significantly higher than those who delivered term infants (p = .05; p = .004, respectively). This suggests those who smoked during pregnancy had a greater degree of belief that Chance influenced their infant's health status. Cultural differences also emerged specific to the impact of health care providers on PTB; with Hispanic women scoring Powerful Others the highest among the groups (p = .02). Nurses can plan a critical role in identifying at-risk women (smoking, strong Chance beliefs) while providing a clear message that taking action and modifying high-risk behaviors can reduce risk for adverse pregnancy outcome. © The Author(s) 2013.

  16. Birth planning and sterilization in China.

    Short, S E; Linmao, M; Wentao, Y

    2000-11-01

    Sterilization is the most prevalent method of contraception in China. Approximately half of all women of reproductive age report that they or their husbands are sterilized. Using data from the China Health and Nutrition Survey we describe patterns of sterilization in eight Chinese provinces. With a discrete-time event history model we investigate the link between characteristics of local birth planning policy and the risk of sterilization. After controlling for parity, the risk of sterilization is highest in communities where birth planning policy is least strong as measured by exceptions to the one-child policy. These results suggest that couples with more flexibility in family building may have less control over contraceptive method use. Other factors affecting the risk of sterilization are a woman's age, parity, and whether or not she has a son. Our results emphasize the importance of taking into account multiple dimensions of reproductive behaviour when assessing one-child policy changes.

  18. New low-dose, extended-cycle pills with levonorgestrel and ethinyl estradiol: an evolutionary step in birth control.

    Nelson, Anita

    2010-08-09

    To review milestones in development of oral contraceptive pills since their introduction in the US 50 years ago in order to better understand how a new formulation with low-dose estrogen in an extended-cycle pattern fits into the evolution of birth control pills. This is a review of trends in the development of various birth controls pills and includes data from phase III clinical trials for this new formulation. The first birth control pill was a very high-dose monophasic formulation with the prodrug estrogen mestranol and a first-generation progestin. Over the decades, the doses of hormones have been markedly reduced, and a new estrogen and several different progestins were developed and used in different dosing patterns. The final element to undergo change was the 7-day pill-free interval. Many of these same changes have been made in the development of extended-cycle pill formulation. The newest extended-cycle oral contraceptive formulation with 84 active pills, each containing 20 μg ethinyl estradiol and 100 μg levonorgestrel, represents an important evolution in birth control that incorporates lower doses of estrogen (to reduce side effects and possibly reduce risk of thrombosis), fewer scheduled bleeding episodes (to meet women's desires for fewer and shorter menses) and the use of low-dose estrogen in place of placebo pills (to reduce the number of days of unscheduled spotting and bleeding). Hopefully, this unique formation will motivate women to be more successful contraceptors.

  19. Phase and gain control policies for robust active vibration control of flexible structures

    2013-01-01

    The interest of this paper is to develop a general and systematic robust control methodology for active vibration control of flexible structures. For this purpose, first phase and gain control policies are proposed to impose qualitative frequency-dependent requirements on the controller to consider a complete set of control objectives. Then the proposed control methodology is developed by employing phase and gain control policies in the dynamic output feedback H ∞  control: according to the set of control objectives, phase and gain control policies incorporate necessary weighting functions and determine them in a rational and systematic way; on the other hand, with the appropriate weighting functions efficient H ∞  control algorithms can automatically realize phase and gain control policies and generate a satisfactory H ∞  controller. The proposed control methodology can be used for both SISO and MIMO systems with collocated or non-collocated sensors and actuators. In this paper, it is validated on a non-collocated piezoelectric cantilever beam. Both numerical simulations and experimental results demonstrate the effectiveness of the proposed control methodology. (paper)

    To determine if the use of hydrocortisone cream decreases perineal pain in the immediate postpartum period. This was a randomized controlled trial (RCT), crossover study design, with each participant serving as their own control. Participants received three different methods for perineal pain management at three sequential perineal pain treatments after birth: two topical creams (corticosteroid; placebo) and a control treatment (no cream application). Treatment order was randomly assigned, with participants and investigators blinded to cream type. The primary dependent variable was the change in perineal pain levels (posttest minus pretest pain levels) immediately before and 30 to 60 minutes after perineal pain treatments. Data were analyzed with analysis of variance, with p creams, with average perineal pain change scores of -4.8 ± 8.4 mm after treatment with hydrocortisone cream (N = 27) and -6.7 ± 13.0 mm after treatment with the placebo cream (N = 27). Changes in pain scores with no cream application were 1.2 ± 10.5 mm (N = 27). Analysis of variance found a significant difference between treatment groups (F2,89 = 3.6, p = 0.03), with both cream treatments having significantly better pain reduction than the control, no cream treatment (hydrocortisone vs. no cream, p = 0.04; placebo cream vs. no cream, p = 0.01). There were no differences in perineal pain reduction between the two cream treatments (p = .54). This RCT found that the application of either hydrocortisone cream or placebo cream provided significantly better pain relief than no cream application.

  1. International trade agreements: a threat to tobacco control policy.

    Shaffer, E R; Brenner, J E; Houston, T P

    2005-08-01

    International covenants establish a role for governments in ensuring the conditions for human health and wellbeing, which has been recognised as a central human right. International trade agreements, conversely, prioritize the rights of corporations over health and human rights. International trade agreements are threatening existing tobacco control policies and restrict the possibility of implementing new controls. This situation is unrecognised by many tobacco control advocates in signatory nations, especially those in developing countries. Recent agreements on eliminating various trade restrictions, including those on tobacco, have expanded far beyond simply international movement of goods to include internal tobacco distribution regulations and intellectual property rules regulating advertising and labelling. Our analysis shows that to the extent trade agreements protect the tobacco industry, in itself a deadly enterprise, they erode human rights principles and contribute to ill health. The tobacco industry has used trade policy to undermine effective barriers to tobacco importation. Trade negotiations provide an unwarranted opportunity for the tobacco industry to assert its interests without public scrutiny. Trade agreements provide the industry with additional tools to obstruct control policies in both developed and developing countries and at every level. The health community should become involved in reversing these trends, and help promote additional measures to protect public health.

    Background Syphilis is a major public health problem in many regions of China, with increases in congenital syphilis (CS) cases causing concern. The Chinese Ministry of Health recently announced a comprehensive 10-y national syphilis control plan focusing on averting CS. The decision analytic model presented here quantifies the impact of the planned strategies to determine whether they are likely to meet the goals laid out in the control plan. Methods and Findings Our model incorporated data on age-stratified fertility, female adult syphilis cases, and empirical syphilis transmission rates to estimate the number of CS cases associated with prenatal syphilis infection on a yearly basis. Guangdong Province was the focus of this analysis because of the availability of high-quality demographic and public health data. Each model outcome was simulated 1,000 times to incorporate uncertainty in model inputs. The model was validated using data from a CS intervention program among 477,656 women in China. Sensitivity analyses were performed to identify which variables are likely to be most influential in achieving Chinese and international policy goals. Increasing prenatal screening coverage was the single most effective strategy for reducing CS cases. An incremental increase in prenatal screening from the base case of 57% coverage to 95% coverage was associated with 106 (95% CI: 101, 111) CS cases averted per 100,000 live births (58% decrease). The policy strategies laid out in the national plan led to an outcome that fell short of the target, while a four-pronged comprehensive syphilis control strategy consisting of increased prenatal screening coverage, increased treatment completion, earlier prenatal screening, and improved syphilis test characteristics was associated with 157 (95% CI: 154, 160) CS cases averted per 100,000 live births (85% decrease). Conclusions The Chinese national plan provides a strong foundation for syphilis control, but more comprehensive measures

    In many western countries, pregnant women often prepare birth plans, outlining how they would like their childbirth experiences to proceed. However there have been no experimental studies to evaluate the effect of birth plans. The objective of this research was to evaluate the effects of birth plans on women's fulfilment of their childbirth expectations, their control over the birth process, and overall experiences. A randomised, single-blind controlled trial study design was used. This study involved seven hospitals and 10 obstetricians in Taiwan. Participants included primiparous women, each under the care of one of seven Taiwanese medical facilities, and who had been pregnant for at least 32 weeks. They were also at least 18 years old, and had no pregnancy complications. An exclusion criterion was elective caesarean as a mode of delivery. A total of 296 women in hospital clinics who met the study criteria were allocated by block randomisation to experimental (n=155) or control (n=141) groups. The women completed their basic personal information and a childbirth expectations questionnaire when they were recruited. One day after delivery, all the participants completed a questionnaire about the childbirth experience, control and fulfilment of their childbirth expectations. The experimental group had a statistically higher degree of positive childbirth experiences than that of the control group (t=2.48, p=0.01). The experimental group also showed a higher degree of childbirth control (t=9.60, pcontrol groups in prenatal birth expectations, but a significant difference (t=2.63, p=0.01) in the degree of fulfilment of their childbirth expectations after delivery. On a subscale measuring the fulfilment of childbirth expectations, there was a statistically higher degree of mastery and participation (t=3.74, pcontrol group. The results justify the clinical implementation of birth plans. Providing birth plans in medical facilities is an effective means of fulfilling

    In 1949, Mao Tse-tung professed that overpopulation could not occur under communism and more people and socialist organization leads only to more wealth and power. Yet 3 decades later communist China has adopted Malthusian population policies claiming them as socialist with a Chinese approach. This shift is ideology came about due to rapid population growth, concomitant food shortages, and insufficient economic growth. Since 1982 China has added 13 million persons/year to its population of 1 billion. In 1963, urban fertility began to decline from 6 children/woman to 3 at the end of the decade. The early 1970s marked the beginning of the politicization of birth control. Unlike Western nations and other developing countries that emphasize the health of mothers and children in their family planning campaigns, China emphasizes political goals. For example, the Chinese purports that family planning can speed world revolution by reducing family size. The Chinese prefer to persuade others to use contraceptives rather than coercing them to do so. Actually Chinese prefer very small families (2 in urban areas and 2 in rural areas). This persuasion and the introduction of oral contraceptives (OCs) and a simpler technique for female sterilization (minilaparotomy) contributed to the high contraceptive usage of 70% for couples of childbearing age and a high abortion rate of 318/1000 live birth by the end of the 1970s. The Chinese constitution states that family planning is the duty of each couple rather than a right. Further, the government has a 1 child/couple population policy. Even though China has had many successes, it has not reached a below replacement level (1989 total fertility rate=2.4), however.

    This study compared obstetric units practicing routine or selective umbilical cord blood gas analysis, with respect to the risk of missing samples in high-risk deliveries and in infants with birth asphyxia. This was a Swedish population-based cohort study that used register data for 155 235 deliveries of live singleton infants between 2008 and 2014. Risk ratios and 95% confidence intervals were calculated to estimate the association between routine and selective umbilical cord blood gas sampling strategies and the risk of missing samples. Selective sampling increased the risk ratios when routine sampling was used as the reference, with a value of 1.0, and these were significant in high-risk deliveries and birth asphyxia. The risk ratios for selective sampling were large-for-gestational age (9.07), preterm delivery at up to 36 weeks of gestation (8.24), small-for-gestational age (7.94), two or more foetal scalp blood samples (5.96), an Apgar score of less than seven at one minute (2.36), emergency Caesarean section (1.67) and instrumental vaginal delivery (1.24). Compared with routine sampling, selective umbilical cord blood gas sampling significantly increased the risks of missing samples in high-risk deliveries and in infants with birth asphyxia. ©2016 Foundation Acta Paediatrica.

    Full Text Available According to World Health Organisation figures, 30% of all cancer deaths, 20% of all coronary heart diseases and strokes and 80% of all chronic obstructive pulmonary disease are caused by cigarette smoking. Environmental Tobacco Smoke (ETS exposure has also been shown to be associated with disease and premature death in non-smokers. In response to this environmental health issue, several countries have brought about a smoking ban policy in public places and in the workplace. Countries such as the U.S., France, Italy, Ireland, Malta, the Netherlands, Sweden, Scotland, Spain, and England have all introduced policies aimed at reducing the population exposure to ETS. Several investigations have monitored the effectiveness of these smoking ban policies in terms of ETS concentrations, human health and smoking prevalence, while others have also investigated a number of alternatives to smoking ban policy measures. This paper reviews the state of the art in research, carried out in the field of ETS, smoking bans and Tobacco Control to date and highlights the need for future research in the area.

    Despite the marked decline in Singapore's crude birth rate from 42.7/1000 population to 22.1/1000 population from 1957 to 1970, the government adopted a policy of sterilization by coercion with the passage in 1970 of the Voluntary Sterilisation Act. Although sterilization is supposedly voluntary, various regulations make it extremely difficult for couples who wish to retain their fertility. Couples under 40 years of age with more than 2 children must agree to accept sterilization or their children are assigned to a low priority category in regard to primary school admittance. An individual who wishes to marry a non-Singaporean cannot obtain a marriage application unless one of the parties to the marriage agrees to have a sterilization after the birth of their 2nd child. Singapore, with a population density of almost 4000/square kilometer, needs to be concerned about population growth; however, since the population had for the most part already adopted a 2 child family norm, these coercive policies appear to be blatantly excessive.

We aimed to investigate whether season of birth influences the risk of rheumatoid arthritis, Crohn's disease, ulcerative colitis and systemic lupus erythematosus in addition to multiple sclerosis, and to explore the correlation between the risk of ID and predicted ultraviolet B (UVB light exposure and vitamin D status during gestation. Methods The monthly distribution of births of patients with ID from the UK (n = 115,172 was compared to that of the general population using the Cosinor test. Predicted UVB radiation and vitamin D status in different time windows during pregnancy were calculated for each month of birth and correlated with risk of ID using the Spearman's correlation coefficient. Results The distributions of ID births significantly differed from that of the general population (P = 5e-12 with a peak in April (odds ratio = 1.045, 95% confidence interval = 1.024, 1.067, P P P = 0.00005 and third trimester vitamin D status (Spearman's rho = -0.44, P = 0.0003. Conclusions The risk of different ID in the UK is significantly influenced by the season of birth, suggesting the presence of a shared seasonal risk factor or factors predisposing to ID. Gestational UVB and vitamin D exposure may be implicated in the aetiology of ID.

    Full Text Available Abstract Background South Africa is one of the major users of pesticides on the African continent. The Eastern Cape is the second largest province in South Africa. There has been growing concern about the occurrence of certain birth defects which seemed to have increased in the past few years. In this paper we investigate associations between exposure to agricultural chemicals and certain birth defects. Few such studies have been undertaken in the developing world previously. Methods Between September 2000 and March 2001 a case – control study was conducted among rural women in the area of the Eastern cape to investigate the association between women's exposure to pesticides and the occurrence of birth defects. Information on birth defects was obtained from the register of the Paediatrics Department at the Cecilia Makiwane Hospital in Mdantsane, one of the largest referral hospitals in the province. The cases were children who were diagnosed with selected birth defects. The controls were children born in the same areas as the cases. Exposure information on the mothers was obtained by interview concerning from their activities in gardens and fields. Data were analysed using conditional logistic regression. Results A total of 89 case mothers and 178 control mothers was interviewed. Babies with birth defects were seven times more likely to be born to women exposed to chemicals used in gardens and fields compared to no reported exposure (Odds Ratio 7.18, 95% CI 3.99, 13.25; and were almost twice as likely to be born to women who were involved in dipping livestock used to prevent ticks (OR 1.92, 95% CI 1.15, 3.14. They were also 6.5 times more likely to be born to women who were using plastic containers for fetching water (OR 6.5, 95% CI 2.2, 27.9. Some of these containers had previously contained pesticides (OR 1.87, 95% CI 1.06, 3.31. Conclusions These findings suggest a link between exposure to pesticides and certain birth defects among the

    Community mobilisation through participatory women's groups might improve birth outcomes in poor rural communities. We therefore assessed this approach in a largely tribal and rural population in three districts in eastern India. From 36 clusters in Jharkhand and Orissa, with an estimated population of 228 186, we assigned 18 clusters to intervention or control using stratified randomisation. Women were eligible to participate if they were aged 15-49 years, residing in the project area, and had given birth during the study. In intervention clusters, a facilitator convened 13 groups every month to support participatory action and learning for women, and facilitated the development and implementation of strategies to address maternal and newborn health problems. The primary outcomes were reductions in neonatal mortality rate (NMR) and maternal depression scores. Analysis was by intention to treat. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN21817853. After baseline surveillance of 4692 births, we monitored outcomes for 19 030 births during 3 years (2005-08). NMRs per 1000 were 55.6, 37.1, and 36.3 during the first, second, and third years, respectively, in intervention clusters, and 53.4, 59.6, and 64.3, respectively, in control clusters. NMR was 32% lower in intervention clusters adjusted for clustering, stratification, and baseline differences (odds ratio 0.68, 95% CI 0.59-0.78) during the 3 years, and 45% lower in years 2 and 3 (0.55, 0.46-0.66). Although we did not note a significant effect on maternal depression overall, reduction in moderate depression was 57% in year 3 (0.43, 0.23-0.80). This intervention could be used with or as a potential alternative to health-worker-led interventions, and presents new opportunities for policy makers to improve maternal and newborn health outcomes in poor populations.

    To evaluate the association between low-dose aspirin initiated before conception and the risk of preterm birth. This was a secondary analysis of the Effects of Aspirin in Gestation and Reproduction trial. Women with a history of pregnancy loss (original stratum: one loss less than 20 weeks of gestation during the previous year; expanded stratum: one or two losses with no restrictions on timing or gestational age of the losses) were randomized to either daily low-dose aspirin (81 mg, n=615) and folic acid or folic acid alone (placebo; n=613). Preterm birth was compared between groups using intent-to-treat analysis. Preterm birth rates were 4.1% (22/535 low-dose aspirin) and 5.7% (31/543 placebo) (relative risk [RR] 0.72, 95% confidence interval [CI] 0.42-1.23); spontaneous preterm birth rates were 1.1% (6/535 low-dose aspirin) and 2.2% (12/543 placebo) (RR 0.51, 95% CI 0.19-1.34); medically indicated preterm birth rates were 2.6% (14/535 low-dose aspirin) and 2.9% (16/543 placebo) (RR 0.89, 95% CI 0.44-1.80). After restriction to confirmed pregnancies using inverse probability weighting, preterm birth rates were 5.7% and 9.0% (RR 0.63, 95% CI 0.37-1.09) and spontaneous preterm birth rates were 1.4% and 3.2% (RR 0.44, 95% CI 0.17-1.18). In confirmed pregnancies in the original stratum, preterm birth occurred in 3.8% and 9.7% of the low-dose aspirin and placebo groups, respectively (RR 0.39, 95% CI 0.16-0.94). Preconception low-dose aspirin was not significantly associated with the overall rate of preterm birth. Although the study was underpowered for this secondary analysis, numeric trends in favor of benefit, particularly in the women with a recent, single early pregnancy loss, warrant further investigation.

    Folic acid (FA) may have a role in the prevention of pregnancy complications. However, the efficacy of FA supplementation in reducing the risk of preterm birth (PTB) is still unclear. The aim of this systematic review with meta-analysis was to evaluate the efficacy of folic acid supplementation during pregnancy to prevent preterm birth (PTB). The research protocol was designed a priori, defining methods for searching the literature in electronic databases, including and examining articles, and extracting and analyzing data. We included all randomized trials (RCTs) of asymptomatic singleton gestations without prior PTB who were randomized to prophylactic treatment with either FA supplementation or control (placebo or no treatment). The primary outcome was the incidence of PTB supplementation had a similar rate of PTB birth weight (mean difference 85.58g, 95% CI -55.17-226.34), low birth weight (21.0% vs 15.1%; RR 0.79, 95% CI 0.49 to 1.28) and perinatal death (2.9% vs 2.4%; RR 0.90, 95% CI 0.60-1.34). In summary, FA supplementation during pregnancy does not prevent PTB supplementation remains the most important intervention to reduce the risk of neural tube defects.

    Purpose We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. Methods We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002–2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. Results Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%–7% higher in 2009. Conclusions Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking. PMID:24268360

    To induce consumers to purchase healthier foods and beverages, some policymakers have suggested special taxes or labels on unhealthy products. The potential of such policies is unknown. In a controlled field experiment, researchers tested whether consumers were more likely to purchase healthy products under such policies. From October to December 2011, researchers opened a store at a large hospital that sold a variety of healthier and less-healthy foods and beverages. Purchases (N=3680) were analyzed under five conditions: a baseline with no special labeling or taxation, a 30% tax, highlighting the phrase "less healthy" on the price tag, and combinations of taxation and labeling. Purchases were analyzed in January-July 2012, at the single-item and transaction levels. There was no significant difference between the various taxation conditions. Consumers were 11 percentage points more likely to purchase a healthier item under a 30% tax (95% CI=7%, 16%, pproduct type, consumers switched away from the purchase of less-healthy food under taxation (9 percentage point decrease, ptax rates proposed in public policy discussions would be more effective than labeling products as less healthy.

    The purpose of this study was to identify Nevada legislators' views on comprehensive smoke-free (SF) policy development. The Nevada Clean Indoor Air Act (NCIAA) is a weak law that prohibits smoking in most indoor public places, excluding stand-alone bars and casino gaming areas. Nevada's state senators and assembly members were contacted to participate in the study. A literature review guided modifications of an instrument previously used to measure county-level officials' policy views in Kentucky. Descriptive statistics were conducted for selected variables, while independent t tests and one-way analysis of variance were used to examine differences between various groups. 23 of 63 legislators participated. Even though the majority of officials recognized smoking as a health hazard and nicotine as addictive, there was not overwhelming support for strengthening the NCIAA, raising cigarette excise taxes or providing cessation benefits to citizens. Officials believed that the NCIAA was having a negative economic impact on smaller gaming businesses, but not on the casino industry. Democrats were more likely than Republicans to agree that raising the excise tax by $1 is important for needed state revenues. 63% of legislators believed that they would be persuaded to strengthen the NCIAA regardless of its financial impact on small businesses, if their constituents supported such a move. No other state relies on gaming revenues as much as Nevada. Given that legislators are strongly influenced by their constituents' views, policy advocates need to establish grassroots support for strengthening the current NCIAA and also tobacco control laws in general.

Over the decades, the doses of hormones have been markedly reduced, and a new estrogen and several different progestins were developed and used in different dosing patterns. The final element to undergo change was the 7-day pill-free interval. Many of these same changes have been made in the development of extended-cycle pill formulation.Conclusion: The newest extended-cycle oral contraceptive formulation with 84 active pills, each containing 20 μg ethinyl estradiol and 100 μg levonorgestrel, represents an important evolution in birth control that incorporates lower doses of estrogen (to reduce side effects and possibly reduce risk of thrombosis, fewer scheduled bleeding episodes (to meet women’s desires for fewer and shorter menses and the use of low-dose estrogen in place of placebo pills (to reduce the number of days of unscheduled spotting and bleeding. Hopefully, this unique formation will motivate women to be more successful contraceptors.Keywords: extended-cycle oral contraceptives, low-dose extended-cycle pills, Lo Seasonique

    This study aims to examine the impact of childbirth education in Turkey on the adaptation to pregnancy process, concerns about birth, rate of vaginal birth, and adaptation to maternity. This quasi-experimental study with control group was conducted from December 2013 to December 2014. The sample size was 132 primiparous pregnant women ( n experimental = 66, n control = 66). The average age of the pregnant women in the experimental and control groups was 24.41 ± 3.92 and 23.68 ± 4.19, respectively. The study showed that experimental group participants had lower concerns about birth, higher levels of knowledge, and faster adaptation to pregnancy and postpartum process; they could also give positive feedback about labor pain and action and could start breastfeeding at an earlier stage when compared with those in the control group ( p process.

    A number of factors have retarded the acceptance of birth control methods among peasant communities in Egypt: 1) the religious world-view of the peasant discourages him from interfering with the natural process of procreation; 2) the large family is important socially and economically in peasant society for strength and security and for the distribution of labor; 3) the status of a married woman depends to a great extent on the number of children, particularly the number of sons, she bears; and 4) in the Egyptian village, the midwife discourages the use of contraception. Acceptance and utilization of birth control methods in Egypt are directly proportionate to the level of education of the individual. The better the economic status of the family, the smaller the family is likely to be. Demographically, the closer a family lives to Cairo, the more likely it is that birth control techniques are being used. Egyptian family planning programs which take into consideration the difficulties of spreading the acceptance and use of contraceptives in traditional societies are discussed.

    Full Text Available Abstract Background Older paternal age may increase the germ cell mutation rate in the offspring. Maternal age may also mediate in utero exposure to pregnancy hormones in the offspring. To evaluate the association between paternal and maternal age at birth with the risk of breast cancer in female offspring, a case-control study was conducted in Korea. Methods Histologically confirmed breast cancer cases (n = 1,011 and controls (n = 1,011 with no present or previous history of cancer, matched on year of birth and menopausal status, were selected from several teaching hospitals and community in Seoul during 1995–2003. Information on paternal and maternal ages and other factors was collected by interviewed questionnaire. Odds ratio (OR and 95% confidence interval (95% CI were estimated by unconditional logistic regression model adjusting for family history of breast cancer in 1st or 2nd degree relatives, and lifetime estrogen exposure duration. Results The risk of breast cancer significantly increased as the paternal age increased (p for trend = 0.025. The association was stronger after controlling for maternal age; women whose fathers were aged ≥40 years at their birth had 1.6-fold increased risk of breast cancer compared with fathers aged Conclusion These findings suggest that older paternal age increases the risk of breast cancer in their female offspring.

    Starting and advancement of feeding in very low birth weight (VLBW) infants are big challenges for the neonatal practitioners. Wide variations in volume of feed advancement have observed in earlier trials both in slow and rapid advancement groups. Volume advancement in slow advancement groups have ranged from 10ml/kg/day to 23ml/kg/day and in rapid advancement groups have ranged from 15ml/kg/day to 45ml/kg/day in earlier different studies. This randomized controlled trial was conducted in neonatal intensive care unit (NICU) of Bangabandhu Sheikh Mujib Medical University (BSMMU) from April 2013 to July 2014 to evaluate the effects of slow versus rapid rates of feeding advancements on the clinical outcomes in very low birth weight infants. A total 95 infants were enrolled into two strata according to their birth weight. Infants of each stratum were randomly allocated to either slow or rapid advancement group during initiation of feeding. After gut priming over five days, feeding was advanced daily 10ml/kg in slow and 15ml/kg in rapid advancement group for 1000 - rapid advancement group. The primary outcome variable was time taken to achieve full enteral feed. Total 82 infants completed the trial. Demographically both groups were same. Infants in the rapid feeding advancement group achieved full enteral feedings before the slow advancement group, had significantly fewer days of parenteral nutrition and regained birth weight earlier. There were no statistical differences in episodes of feed interruption, number of infants with apnea, feed intolerance or diagnosis of sepsis. Rapid enteral feeding advancements were well tolerated by very low birth weight infants.

    Some studies have noted an association between maternal occupational exposures to chlorinated solvents and birth defects in offspring, but data are lacking on the potential impact of industrial air emissions of these solvents on birth defects. With data from the Texas Birth Defects Registry for births occurring in 1996-2008, we examined the relation between maternal residential proximity to industrial air releases of chlorinated solvents and birth defects in offspring of 60,613 case-mothers and 244,927 control-mothers. Maternal residential exposures to solvent emissions were estimated with metrics that took into account residential distances to industrial sources and annual amounts of chemicals released. Logistic regression was used to generate odds ratios and 95% confidence intervals for the associations between residential proximity to emissions of 14 chlorinated solvents and selected birth defects, including neural tube, oral cleft, limb deficiency, and congenital heart defects. All risk estimates were adjusted for year of delivery and maternal age, education, race/ethnicity, and public health region of residence. Relative to exposure risk values of 0, neural tube defects were associated with maternal residential exposures (exposure risk values >0) to several types of chlorinated solvents, most notably carbon tetrachloride (adjusted odds ratio [aOR] 1.42, 95% confidence interval [CI] 1.09, 1.86); chloroform (aOR 1.40, 95% CI 1.04, 1.87); ethyl chloride (aOR 1.39, 95% CI 1.08, 1.79); 1,1,2-trichloroethane (aOR 1.56, 95% CI 1.11, 2.18); and 1,2,3-trichloropropane (aOR 1.49, 95% CI 1.08, 2.06). Significant associations were also noted between a few chlorinated solvents and oral cleft, limb deficiency, and congenital heart defects. We observed stronger associations between some emissions and neural tube, oral cleft, and heart defects in offspring of mothers 35 years or older, such as spina bifida with carbon tetrachloride (aOR 2.49, 95% CI 1.09, 5.72), cleft palate

    Over 20 experts on economics, epidemiology, public policy and tobacco control were asked by the International Agency for Research on Cancer (IARC) to evaluate the strength of the available evidence on the effects of tax and price policies to prevent and reduce tobacco use. Draft papers presenting and assessing the evidence on the following topics were developed by the experts in an 8-month period prior to the meeting: tobacco industry pricing strategies and tax related lobbying; tax, price and aggregate demand for tobacco; tax, price and adult tobacco use, use among young people and use among the poor; tax avoidance and tax evasion; and the economic and health impact of tobacco taxation. Subsequently, papers were peer reviewed, revised and resubmitted for final discussion at a 6-day meeting at IARC in Lyon, France, where a consensus evaluation of 18 concluding statements using the pre-established criteria of the IARC Cancer Prevention Handbooks took place. Studies published (or accepted for publication) in the openly available scientific literature were the main source of evidence for the review and evaluation; other types of publications were included when appropriate. In support of 12 of the 18 conclusions, the experts agreed that there was sufficient evidence of effectiveness of increased tobacco excise taxes and prices in reducing overall tobacco consumption and prevalence of tobacco use and improvement of public health, including by preventing initiation and uptake among young people, promoting cessation among current users and lowering consumption among those who continue to use. For the remaining six concluding statements the evidence was strong (four statements) or limited (two statements). The evidence presented and assessed in IARC Handbook volume 14 documents the effectiveness of tax and price policies in the control of tobacco use and improvement of public health.

    Schaerer, B.

    1992-01-01

    Since the mid-eighties total annual acidifying emissions have started to decline in West Germany. There was considerable impact on this positive trend in air pollution by the control of SO 2 and NO x emissions from large boilers, which were reduced by more than 80%. Corresponding control programmes have been established for other groups of sources as well as other pollutants and - with unification - for East Germany. The driving force behind this development was and still is first of all the legal principle of anticipatory action or precaution which means in practical terms 'emission minimization'. This cornerstone of German clean air legislation is the most powerful components of Germany's 'acidification policy', as it requires policy-makers to draw up new or review existing regulations for emission reduction based on requirements according to the state of the art and forces operators to apply the most modern ways and means of operation. This paper describes the system used in Germany to deal with air pollution, the emission minimization strategy, and the actions against acidifying emissions based thereon. In addition, an outlook on what might be necessary to cope with the challenges of a sustainable development concerning acidification is given. 1 ref., 1 fig., 2 tabs

The SimSmoke model provides projections of these health outcomes in the face of existing and expanded (simulated) tobacco control polices. The SimSmoke model utilizes population data, smoking rates, and various tobacco control policy measures from Louisiana to predict smoking prevalence and smoking-attributable deaths. The model begins in 1993 and estimates are projected through 2054. The model is validated against existing Louisiana smoking prevalence data. The most powerful individual policy measure for reducing smoking prevalence is cigarette excise tax. However, a comprehensive cessation treatment policy is predicted to save the most lives. A combination of tobacco control policies provides the greatest reduction in smoking prevalence and smoking-attributable deaths. The existing Louisiana excise tax ranks as one of the lowest in the country and the legislature is against further increases. Alternative policy measures aimed at lowering prevalence and attributable deaths are: cessation treatments, comprehensive smoke-free policies, and limiting youth access. These three policies have a substantial effect on smoking prevalence and attributable deaths and are likely to encounter more favor in the Louisiana legislature than increasing the state excise tax.

    Full Text Available Since the 1970s, Israel's educational policy has been undergoing a change generated by the neo-liberal agenda. In this light, it is not surprising that since the 1990s, Israel’s education system has adopted the main characteristics of the Global Education Reform Movement (GERM. In light of this, the current research will focus on a newly born pre-K policy formation process that set out as GERM-like in nature, but nevertheless ended up with anti-GERM characteristics. Using historical-narrative qualitative tools, this paper will portray and analyze the main factors that generated the new anti-GERMian reform. We will outline conclusions from the Israeli case study to create a potential conceptual framework that highlights a more complex, hybrid, or dual outlook at the GERM containing its antidote within itself.

    To examine Korean public opinions toward alcohol control measures on availability, advertisement, drink-driving and pricing policy, and how the views on alcohol control policy vary by demographics, drinking patterns and attitude to drinking environments. The study used national-based, cross-sectional data collected in 2012 as part of the International Alcohol Control study. 2510 people (M: 1163, F: 1261) aged 15-65 and living in geographically diverse regions of Korea completed the questionnaire asking the support of 12 alcohol control measures. Generally, targeted measures (purchase age of 20 and drink-driving) were more popular than universal (availability, advertisement and price) among Koreans. Gender, age, marital status, drinking patterns and attitude to drinking environments related to alcohol use of young and heavy drinkers were strong predictors of the opinions on most of the alcohol control measures. It was daily/weekly drinkers who opposed most restrictions on alcohol availability and price and the support from individuals who are more aware of problems with drinking in public place was outstanding in every control measure. These findings should be taken into account by Korean policy-makers as they formulate an alcohol policy for the country. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Birth control movements that emerged in Europe and the United States during the last third of the nineteenth century lost their emancipatory and feminist potential in the twentieth century as they succumbed to control by the medical profession, eugenicists, and institutionalized goals of planned parenthood. The neo-Malthusian movement in France, however, retained a radical character and became a focal point for the convergence of libertarian, feminist, and anarchist concerns. By emancipating women from their "biological destiny" and separating sexuality and reproduction, neo-Malthusian rhetoric reconfigured womanhood and established the basis for women's development as full individuals and citizens.

    Prenatal supplementation with micronutrients may increase birth weight and thus improve infant health and survival in settings where infants and children are at risk of micronutrient deficiencies. To assess whether vitamin A and/or zinc supplementation given during pregnancy can improve birth weight, birth length, neonatal morbidity, or infant mortality. A double-blind, randomized controlled trial supplementing women (n = 2173) in Central Java, Indonesia throughout pregnancy with vitamin A, zinc, combined vitamin A+zinc, or placebo. Out of 2173 supplemented pregnant women, 1956 neonates could be evaluated. Overall, zinc supplementation improved birth length compared to placebo or combined vitamin A+zinc (48.8 vs. 48.5 cm, p = 0.04); vitamin A supplementation improved birth length compared to placebo or combined vitamin A+zinc (48.7 vs. 48.2 cm, p = 0.04). These effects remained after adjusting for maternal height, pre-pregnancy weight, and parity. There was no effect of supplementation on birth weight, the proportion of low birth weight, neonatal morbidity, or mortality. Prenatal zinc or vitamin A supplementation demonstrates a small but significant effect on birth length, but supplementation with zinc, vitamin A or a combination of zinc and vitamin A, have no effect on birth weight, neonatal morbidity, or mortality.

    Objective The aim of the present study was to examine non-communicable disease (NCD) policy formation and implementation in Indonesia. Methods Interviews were conducted with 13 Indonesian health policy workers. The processes and issues relating to NCD policy formation were mapped, exploring the interactions between policy makers, technical/implementation bodies, alliances across various levels and the mobilisation of non-policy actors. Results Problems in NCD policy formation include insufficient political interest in NCD control, disconnected policies and difficulty in multisectoral coordination. These problems are well illustrated in relation to tobacco control, but also apply to other control efforts. Nevertheless, participants were optimistic that there are plentiful opportunities for improving NCD control policies given growing global attention to NCD, increases in the national health budget and the growing body of Indonesia-relevant NCD-related research. Conclusion Indonesia's success in the creation and implementation of NCD policy will be dependent on high-level governmental leadership, including support from the President, the Health Minister and coordinating ministries. What is known about the topic? The burden of NCD in Indonesia has increased gradually. Nationally, NCD-related mortality accounted for 65% of deaths in 2010. Indonesia is also a country with the highest burden of tobacco smoking in the world. However, the government has not instituted sufficient policy action to tackle NCDs, including tobacco control. What does this paper add? This paper deepens our understanding of current NCD control policy formation in Indonesia, including the possible underlying reason why Indonesia has weak tobacco control policies. It describes the gaps in the current policies, the actors involved in policy formation, the challenges in policy formation and implementation and potential opportunities for improving NCD control. What are the implications for

    There is strong evidence that exclusive breastfeeding (EBF) in the first 6 months of life reduces the risk of diseases in infancy and in later life. To understand the maternal reasoning that influences optimum infant feeding practices of caregivers in semirural communities of Limpopo province. Nested qualitative study among mothers in an ongoing birth cohort study was conducted; structured and semi-structured interviews were used to collect data. Data from 234 infants after 6 months of follow-up was included for quantitative analysis. Four focus discussion groups comprising 7 to 10 caregivers were used to obtain perception of mothers on breastfeeding. A semi-structured interview guide was used to stimulate discussions. Thematic content analyses were conducted to identify the main themes that influence breastfeeding practices of caregivers. Over 90% of the caregivers initiated breastfeeding after delivery. However, less than 1% of mothers practiced EBF by 3 months, and none of the children were exclusively breastfed for up to 6 months. All caregivers introduced non-breast milk liquids and solids by the second month of child's life. Common reasons for introducing non-breast milk foods included insufficiency of breast milk production, going back to work or school, and influence by elderly women (mothers/mothers-in-law) and church members. Exclusive breastfeeding was not practiced in this community due to cultural and religious beliefs and misinformation. The involvement of elderly women and church members in infant feeding education and promotion programs and the dissemination of breastfeeding information through mobile phones to younger mothers are recommended.

    Preterm birth has been associated with increased parenting stress in early infancy, and some reports have found this to be a risk factor for later behavioral problems. There are, however, few studies and conflicting results. Information about the fathers is scarce. Our goal was to study the effects of an early-intervention program on parenting stress after a preterm birth until 1 year corrected age. A randomized, controlled trial was conducted including infants with a birth weight effects of a modified version of the Mother-Infant Transaction Program on parenting stress measured by the Parenting Stress Index. A term control group was also recruited. The Parenting Stress Index was administered to the mothers at 6 and 12 months' corrected age and to the fathers at 12 months' corrected age. The intervention consisted of 8 sessions shortly before discharge and 4 home visits by specially trained nurses focusing on the infant's unique characteristics, temperament, and developmental potential and the interaction between the infant and the parents. Seventy-one infants were included in the preterm intervention group, and 69 were included in the preterm control group. The preterm groups were well balanced. Seventy-four infants were included in the term control group. Compared with the preterm controls, both the mothers and fathers in the preterm intervention group reported significant lower scores in child domain, parent domain, and total stress on all occasions except the mother-reported child domain at 12 months. These differences were not related to birth weight or gestational age. The level of stress among the preterm intervention group was comparable to their term peers. Both parents in the intervention group reported consistently lower scores within the distractibility/hyperactivity, reinforces parents, competence, and attachment subscales compared with the preterm control group. There were no differences in mean summary stress scores between the mothers and fathers in

    Background Since the political transition in 1991, Russia has been targeted intensively by the transnational tobacco industry. Already high smoking rates among men have increased further; traditionally low rates among women have more than doubled. The tobacco companies have so far faced little opposition as they shape the discourse on smoking in Russia. This paper asks what ordinary Russians really think about possible actions to reduce smoking. Methods A representative sample of the Russian population (1600 respondents) was interviewed face-to-face in November 2007. Results Only 14% of respondents considered tobacco control in Russia adequate, while 37% felt that nothing was being done at all. There was support for prices keeping pace with or even exceeding inflation. Over 70% of all respondents favoured a ban on sales from street kiosks, while 56% believed that existing health warnings (currently 4% of front and back of packs) were inadequate. The current policy of designating a few tables in bars and restaurants as non-smoking was supported by less than 10% of respondents, while almost a third supported a total ban, with 44% supporting provision of equal space for smokers and non-smokers. Older age, non-smoking status and living a smaller town all emerged as significantly associated with the propensity to support of antismoking measures. The tobacco companies were generally viewed as behaving like most other companies in Russia, with three-quarters believing that they definitely or maybe bribe politicians. Knowledge of impact of smoking on health was limited with significant underestimation of dangers and addictive qualities of tobacco. A third believed that light cigarettes are safer than normal. Conclusion The majority of the Russian population would support considerable strengthening of tobacco control policies but there is also a need for effective public education campaigns.

    This study aims to determine whether periodontal conditions or dental health behaviors are risk factors for preterm birth (PTB), and whether periodontal pathogens are risk indicators for PTB among Korean mothers. This study was designed as a hospital-based case-control study. Examiner masking was ensured for the validity of the examinations. The mothers included those who gave birth between November 2007 and July 2009 at the obstetrics clinic of a general hospital in Seoul, Korea. Information on demographic and health conditions, periodontal conditions, and microbacterial data was collected. A total of 172 women met the inclusion criteria, 59 mothers who delivered a preterm neonate were assigned to the case group while the other 113 were assigned to the control group. There were no significant differences in demographic information, oral health conditions, and obstetric characteristics. Among health-related behaviors, only scaling within 12 months before pregnancy showed a significant difference (P = 0.031). Even in the adjusted logistic model, only the difference in the experience of scaling before pregnancy was significant between the PTB cases and the controls (P = 0.039). Periodontal disease did not exhibit a significant relationship with PTB even after adjustment for potential confounding factors. Among the microbacterial factors, only Porphyromonas gingivalis showed a slight difference (P = 0.060). There was a significant difference in scaling experience within 12 months before pregnancy and P. gingivalis showed a marginal difference between the PTB and the control groups but clinical periodontal conditions showed no association with PTB.

This study assessed trends in utilization of SBAs in Nigeria between 1990 and 2013 and identified its determinants.Methods: Data from four consecutive Nigerian Demographic and Health Survey reports between 1990 and 2013 were pooled. We used basic descriptive statistics, test of association, and logistic regression to assess the prevalence, relative change, and determinants of SBA use at 5% significance level. Sample weights were applied, and adjustment was made for survey design and sampling errors.Results: Nearly half (46.7% of the respondents were aged 25–34 years, while half (50.3% of the respondents had no formal education. The prevalence of SBA use increased only marginally across the years and characteristics studied, from 32.4% in 1990 to 38.5% in 2013, an insignificant 6% increase. Educated women used SBA more than women with no education (92.4% vs 13.1%, and their odds ratio of using SBA were thrice that of uneducated women (odds ratio =3.09, 95% confidence interval =2.17–4.38. Women involved in decisions regarding their use of health facility were 12% more likely to use SBAs than others who do not.

    Tobacco control policies reduce the health and economic burden caused by tobacco. With over half of the United States communities lacking adequate protective policies, an examination of policy adoption factors can provide insights to facilitate policy adoption. A case study approach examines the rate of adoption, prominent media frames, policy leaders' perceptions and coalition activities for smokefree and Tobacco 21 policies adopted in Missouri. Findings show compared to smokefree policy, Tobacco 21 requires a considerably shorter timeframe and fewer resources for adoption. Tobacco 21 coalitions target a small group of stakeholders compared to smokefree coalitions' emphasis on broad community engagement. Both policies are formally opposed, but elected officials perceive less political risk supporting Tobacco 21. As a new tobacco control policy tool, Tobacco 21 has relative advantage that should be considered by community health advocates.

    Although worksite smoking restrictions have become increasingly common in recent years, organized labor has generally not been involved in the adoption of these policies; some evidence suggests that unions often oppose the adoption of worksite smoking policies. To contribute to an understanding of labor's role in tobacco control policies, this paper reports the results of a review of 85 arbitration cases and 5 cases of unfair labor practices charges published between 1986 and 1994. In most of the cases reviewed, management unilaterally imposed a new smoking policy, which the union then grieved. Union opposition to the policy generally focused on the process by which the policy was adopted, rather than the content of the policy; the concern was that management had breached its duty to bargain with the union regarding the adoption of the policy. These results underline the importance of joint labor-management actions on worksite tobacco control policies.

    Low birth weight is one of the most important public health issues in developing and developed countries and identifying its etiology is important for prevention. Considering the unknown impact of physical activity on low birth weight, this research was conducted to investigate the relationship between physical activity and low birth weight. This research was conducted using a case-control design. The control group was made of 500 women with normal birth weight infants and the case group included 250 women with low birth weight infants from the selected hospitals in city of Tehran. The information was gathered using a researcher-made questionnaire which was prepared for determining the relationship between mothers' lifestyle during pregnancy and infants' low birth weight using social determinants of health approach. In this questionnaire, scope of physical activity was investigated in three groups of athletic activities, activities at home and leisure activities. Activity intensity was determined using MET scale and the data were analyzed in SPSS software using independent t-test, Chi-square and logistic regression. In the present research, based on the results of multiple logistic regression test, an increase in the time spent on sport activities (OR = 2.20) and home activities (OR =1.44) (P = 0.003) was accompanied by increased chance of giving birth to low birth weight infants; in contrast, one hour increase of leisure activities decreased the probability of low birth weight infants by 0.32 (P = 0.008). An increase in the time spent on sport and home activities, even after considering other influential factors, was related to low birth weight.

    Our aims were to examine the impact of cigarette taxes and smoke-free legislation on current adolescent smoking and smoking frequency overall as well as test whether there were differential policy effects by age. Using data on 717,543 adolescents from 43 states in the 1999-2013 Youth Risk Behavior Surveys, we used difference-in-differences regression models to evaluate the impact of tobacco control policies on current adolescent smoking (yes/no) and, separately, smoking frequency (defined as 0, 1-5, 6-29, 30+ days per month). We tested an interaction between age and cigarette taxes and, separately, smoke-free legislation. From 1999 to 2013, adolescent smoking decreased from 35.3% to 13.9% and 41 of 43 states increased their cigarette tax in real terms by an average of 257%. By the end of the study period, 29 of 43 states had 100% smoke-free restaurant legislation. Although we found no overall effect of cigarette taxes on current smoking, there was a significant interaction by age. Among 14- and 15-year olds, every $1.00 cigarette tax increase was associated with a 2.2 and 1.6 percentage point reduction in smoking, respectively. The enactment of 100% smoke-free restaurant legislation was associated with an overall reduction in adolescent smoking by 1.1 percentage points and there were no differences by age. Cigarette taxes and smoke-free legislation were also associated with decreased smoking frequency. The youngest adolescents are the most price sensitive, and cigarette taxes continue to be a successful approach to reduce adolescent smoking. Smoke-free legislation may also be an effective strategy to reduce smoking among all adolescents. Copyright © 2016 The Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    The purpose of this study was to evaluate the efficacy of omega-3 supplementation for the prevention of recurrent preterm birth (PTB) in asymptomatic singleton gestations with previous PTB. We searched fish oil, long chain polyunsaturated fatty acids, pregnancy, and omega-3 in MEDLINE, OVID, Scopus, ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, EMBASE, and the Cochrane Central Register of Controlled Trials from inception of each database to December 2014 with no limit for language. In addition the reference lists of all identified articles were examined to identify studies that were not captured by electronic searches. We performed a metaanalysis of randomized controlled trials of asymptomatic singleton gestations with previous PTB who were assigned randomly to prophylactic omega-3 supplementation vs control (either placebo or no treatment). The primary outcome was predefined as PTB at supplementation during pregnancy does not prevent recurrent PTB in asymptomatic singleton gestations with previous PTB. The benefits in longer latency and higher birth weight may deserve further study. Copyright © 2015 Elsevier Inc. All rights reserved.

    Russia has high smoking rates and weak tobacco control policies. A simulation model is used to examine the effect of tobacco control policies on past and future smoking prevalence and premature mortality in Russia. The Russia model was developed using the SimSmoke tobacco control model previously developed for the USA and other nations. The model inputs population size, birth, death and smoking rates specific to Russia. It assesses, individually and in combination, the effect of seven types of policies consistent with the WHO Framework Convention on Tobacco Control (FCTC): taxes, smoke-free air, mass media campaign, advertising bans, warning labels, cessation treatment and youth access policies. Outcomes are smoking prevalence and the number of smoking-attributable deaths by age and gender from 2009 to 2055. Increasing cigarette taxes to 70% of retail price, stronger smoke-free air laws, a high-intensity media campaign and comprehensive treatment policies are each potent policies to reduce smoking prevalence and smoking-attributable premature deaths in Russia. With the stronger set of policies, the model estimates that, relative to the status quo trend, smoking prevalence can be reduced by as much as 30% by 2020, with a 50% reduction projected by 2055. This translates into 2 684 994 male and 1 011 985 female premature deaths averted from 2015-2055. SimSmoke results highlight the relative contribution of policies to reducing the tobacco health burden in Russia. Significant inroads to reducing smoking prevalence and premature mortality can be achieved through strengthening tobacco control policies in line with FCTC recommendations.

    To compare the intervention rates associated with labor in low-risk women who began their labor in the "home-like birth centre" (HLBC) and the traditional labor ward (TLW). This retrospective study used data that were collected from January 2005 to June 2008, from women admitted to the HLBC (n = 316) and compared to a group of randomly selected low-risk women admitted to the TLW (n = 890) using the Baysian information criterion to select the best predictive model. Women in the HLBC had spontaneous vaginal deliveries more often (88.6 vs. 82.8 %, p value 0.034) and perineal lesions less often (60.1 vs. 62.5 %, p value 0.013). The frequency of adverse neonatal outcomes did not differ statistically between the two groups, although the mean clamped at birth umbilical arterial pH level was higher in the HLBC group. The transfer rate from HLBC to TLW was 31.3 % of which 75.8 % were nulliparae. It appears that women could benefit from HLBC care in settings such as the one studied. Larger observational studies are warranted to validate these results.

There is a growing body of research evaluating the effect of acupuncture administered during IVF, and specifically on the day of embryo transfer (ET. Many trials are heterogeneous and results inconsistent. There remains insufficient evidence to determine if acupuncture can enhance live birth rates when used as an adjunct to IVF treatment. The study will determine the clinical effectiveness of acupuncture with improving the proportion of women undergoing IVF having live births. Other objectives include: determination of the cost effectiveness of IVF with acupuncture; and examination of the personal and social context of acupuncture in IVF patients, and examining the reasons why the acupuncture may or may not have worked. Methods We will conduct a randomized controlled trial of acupuncture compared to placebo acupuncture. Inclusion criteria include: women aged less than 43 years; undergoing a fresh IVF or ICSI cycle; and restricted to women with the potential for a lower live birth rate defined as two or more previous unsuccessful ETs; and unsuccessful clinical pregnancies of quality embryos deemed by the embryologist to have been suitable for freezing by standard criteria. Women will be randomized to acupuncture or placebo acupuncture. Treatment is administered on days 6 to 8 of the stimulated cycle and two treatments on the day of ET. A non-randomized cohort of women not using acupuncture will be recruited to the study. The primary study outcome is the proportion of women reporting a live birth. Secondary outcomes include the proportion of women reporting a clinical pregnancy miscarriage prior to 12 weeks, quality of life, and self-efficacy. The sample size of the study is 1,168 women, with the aim of detecting a 7% difference in live births between groups (P

  1. The foxa2 gene controls the birth and spontaneous degeneration of dopamine neurons in old age.

    Full Text Available Parkinson disease affects more than 1% of the population over 60 y old. The dominant models for Parkinson disease are based on the use of chemical toxins to kill dopamine neurons, but do not address the risk factors that normally increase with age. Forkhead transcription factors are critical regulators of survival and longevity. The forkhead transcription factor, foxa2, is specifically expressed in adult dopamine neurons and their precursors in the medial floor plate. Gain- and loss-of-function experiments show this gene, foxa2, is required to generate dopamine neurons during fetal development and from embryonic stem cells. Mice carrying only one copy of the foxa2 gene show abnormalities in motor behavior in old age and an associated progressive loss of dopamine neurons. Manipulating forkhead function may regulate both the birth of dopamine neurons and their spontaneous death, two major goals of regenerative medicine.

    Background Evidence has suggested that periodontal disease is associated with an increased risk of various adverse pregnancy and birth outcomes. However, several large clinical randomized controlled trials failed to demonstrate periodontal therapy during pregnancy reduced the incidence of adverse pregnancy and birth outcomes. It has been suggested that the pre-conception period may be an optimal period for periodontal disease treatment rather than during pregnancy. To date, no randomized cont...

    The Cessation in Pregnancy Incentives Trial (CPIT), which offered financial incentives for smoking cessation during pregnancy showed a clinically and statistically significant improvement in cessation. However, infant birth weight was not seen to be affected. This study re-examines birth weight using an intuitive and a complier average causal effects (CACE) method to uncover important information missed by intention-to-treat analysis. CPIT offered financial incentives up to £400 to pregnant smokers to quit. With incentives, 68 women (23.1%) were confirmed non-smokers at primary outcome, compared to 25 (8.7%) without incentives, a difference of 14.3% (Fisher test, p financial incentives to quit. Viewed in this way, the overall birth weight gain with incentives is attributable only to potential quitters. We compared an intuitive approach to a CACE analysis. Mean birth weight of potential quitters in the incentives intervention group (who therefore quit) was 3338 g compared with potential quitters in the control group (who did not quit) 3193 g. The difference attributable to incentives, was 3338 - 3193 = 145 g (95% CI -617, +803). The mean difference in birth weight between the intervention and control groups was 21 g, and the difference in the proportion who managed to quit was 14.3%. Since the intervention consisted of the offer of incentives to quit smoking, the intervention was received by all women in the intervention group. However, "compliance" was successfully quitting with incentives, and the CACE analysis yielded an identical result, causal birth weight increase 21 g ÷ 0.143 = 145 g. Policy makers have great difficulty giving pregnant women money to stop smoking. This study indicates that a small clinically insignificant improvement in average birth weight is likely to hide an important clinically significant increase in infants born to pregnant smokers who want to stop but cannot achieve smoking cessation without the addition of financial

    Access to quality maternal health services mainly depends on existing policies, regulations, skills, knowledge, perceptions, and economic power and motivation of service givers and target users. Critics question policy recommending involvement of traditional birth attendants (TBAs) in emergency obstetric care (EmoC) services in developing countries. This paper reports about knowledge and practices of TBAs on EmoC in Kigoma Rural District, Tanzania and discusses policy implications on involving TBAs in maternal health services. 157 TBAs were identified from several villages in 2005, interviewed and observed on their knowledge and practice in relation to EmoC. Quantitative and qualitative techniques were used for data collection and analysis depending on the nature of the information required. Among all 157 TBAs approached, 57.3% were aged 50+ years while 50% had no formal education. Assisting mothers to deliver without taking their full pregnancy history was confessed by 11% of all respondents. Having been attending pregnant women with complications was experienced by 71.2% of all respondents. Only 58% expressed adequate knowledge on symptoms and signs of pregnancy complications. Lack of knowledge on possible risk of HIV infections while assisting childbirth without taking protective gears was claimed by 5.7% of the respondents. Sharing the same pair of gloves between successful deliveries was reported to be a common practice by 21.1% of the respondents. Use of unsafe delivery materials including local herbs and pieces of cloth for protecting themselves against HIV infections was reported as being commonly practiced among 27.6% of the respondents. Vaginal examination before and during delivery was done by only a few respondents. TBAs in Tanzania are still consulted by people living in underserved areas. Unfortunately, TBAs' inadequate knowledge on EmOC issues seems to have contributed to the rising concerns about their competence to deliver the recommended maternal

    The history of eugenic sterilization connotes draconian images of coerced and involuntary procedures robbing men and women of their reproductive health. While eugenics programs often fit this characterization, there is another, smaller, and less obvious legacy of eugenics that arguably contributed to a more empowering image of reproductive health. Sexual sterilization surgeries as a form of contraception began to gather momentum alongside eugenics programs in the middle of the 20th century and experiences among prairie women serve as an illustrative example. Alberta maintained its eugenics program from 1929 to 1972 and engaged in thousands of eugenic sterilizations, but by the 1940s middle-class married women pressured their Albertan physicians to provide them with sterilization surgeries to control fertility, as a matter of choice. The multiple meanings and motivations behind this surgery introduced a moral quandary for physicians, which encourages medical historians to revisit the history of eugenics and its relationship to the contemporaneous birth control movement.

    Early age at infection with Hepatitis B virus (HBV) increases the risk of chronic infection. Moreover, early HBV infection may further independently increase the risk of hepatocellular carcinoma (HCC) beyond its effect on chronicity. The distribution of birth order, a proxy for mode and timing of HBV transmission, was compared in The Gambia between hepatitis B surface antigen (HBsAg)-positive HCC cases recruited from hospitals (n = 72) and two HBsAg-positive control groups without HCC: population-based controls from a community HBV screening (n = 392) and hospital-based controls (n = 63). HCC risk decreased with increasing birth order in the population-based case-control analysis. Using first birth order as the reference, the odds ratios were 0.52 (95% CI: 0.20-1.36), 0.52 (0.17-1.56), 0.57 (0.16-2.05) and 0.14 (0.03-0.64) for second, third, fourth and greater than fourth birth order respectively (P = 0.01). A similar inverse association was observed in the hospital-based case-control comparison (P = 0.04). Compared to controls, HCC cases had earlier birth order, a proxy for young maternal age and maternal HBV viraemia at birth. This finding suggests that in chronic HBV carriers perinatal mother-to-infant transmission may increase HCC risk more than horizontal transmission. Providing HBV vaccine within 24 h of birth to interrupt perinatal transmission might reduce the incidence of HCC in The Gambia. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Antenatal preparation programmes are recommended worldwide to promote a healthy pregnancy and greater autonomy during labor and delivery, prevent physical discomfort and high levels of anxiety. The objective of this study was to evaluate effectiveness and safety of a birth preparation programme to minimize lumbopelvic pain, urinary incontinence, anxiety, and increase physical activity during pregnancy as well as to compare its effects on perinatal outcomes comparing two groups of nulliparous women. A randomized controlled trial was conducted with 197 low risk nulliparous women aged 16 to 40 years, with gestational age ≥ 18 weeks. Participants were randomly allocated to participate in a birth preparation programme (BPP; n=97) or a control group (CG; n=100). The intervention was performed on the days of prenatal visits, and consisted of physical exercises, educational activities and instructions on exercises to be performed at home. The control group followed a routine of prenatal care. Primary outcomes were urinary incontinence, lumbopelvic pain, physical activity, and anxiety. Secondary outcomes were perinatal variables. The risk of urinary incontinence in BPP participants was significantly lower at 30 weeks of pregnancy (BPP 42.7%, CG 62.2%; relative risk [RR] 0.69; 95% confidence interval [CI] 0.51-0.93) and at 36 weeks of pregnancy (BPP 41.2%, CG 68.4%; RR 0.60; 95%CI 0.45-0.81). Participation in the BPP encouraged women to exercise during pregnancy (p=0.009). No difference was found between the groups regarding to anxiety level, lumbopelvic pain, type or duration of delivery and weight or vitality of the newborn infant. The BPP was effective in controlling urinary incontinence and to encourage the women to exercise during pregnancy with no adverse effects to pregnant women or the fetuses.

    Public health policies must address multiple goals and complex community health needs. Recently, management control practices have emerged to provide a broader type of information for evaluating the effectiveness of healthcare policies, and relate activities and processes to multiple strategic outcomes. This study compares the effect of traditional and contemporary management control practices on the achievement of public health policies. It is also analyzed how two different uses of such practices (enabling vs. coercive) facilitate the achievement of public health policies. Relationships are explored using data collected from managers from public health agencies and public hospitals in Spain. The findings show that contemporary management control practices are more suitable than traditional practices to achieve public health policies. Furthermore, results show that public health policies are better achieved when managers use management control practices in an enabling way rather than in a coercive way.

  12. The path to impact of operational research on tuberculosis control policies and practices in Indonesia

    2016-02-01

    Full Text Available Background: Operational research is currently one of the pillars of the global strategy to control tuberculosis. Indonesia initiated capacity building for operational research on tuberculosis over the last decade. Although publication of the research in peer-reviewed journals is an important indicator for measuring the success of this endeavor, the influence of operational research on policy and practices is considered even more important. However, little is known about the process by which operational research influences tuberculosis control policy and practices. Objective: We aimed to investigate the influence of operational research on tuberculosis control policy and practice in Indonesia between 2004 and 2014. Design: Using a qualitative study design, we conducted in-depth interviews of 50 researchers and 30 policy makers/program managers and performed document reviews. Transcripts of these interviews were evaluated while applying content analysis. Results: Operational research contributed to tuberculosis control policy and practice improvements, including development of new policies, introduction of new practices, and reinforcement of current program policies and practices. However, most of these developments had limited sustainability. The path from the dissemination of research results and recommendations to policy and practice changes was long and complex. The skills, interests, and political power of researchers and policy makers, as well as health system response, could influence the process. Conclusions: Operational research contributed to improving tuberculosis control policy and practices. A systematic approach to improve the sustainability of the impact of operational research should be explored.

  14. Birth and death of links control disease spreading in empirical contact networks

    Holme, Petter; Liljeros, Fredrik

    2014-05-01

    We investigate what structural aspects of a collection of twelve empirical temporal networks of human contacts are important to disease spreading. We scan the entire parameter spaces of the two canonical models of infectious disease epidemiology--the Susceptible-Infectious-Susceptible (SIS) and Susceptible-Infectious-Removed (SIR) models. The results from these simulations are compared to reference data where we eliminate structures in the interevent intervals, the time to the first contact in the data, or the time from the last contact to the end of the sampling. The picture we find is that the birth and death of links, and the total number of contacts over a link, are essential to predict outbreaks. On the other hand, the exact times of contacts between the beginning and end, or the interevent interval distribution, do not matter much. In other words, a simplified picture of these empirical data sets that suffices for epidemiological purposes is that links are born, is active with some intensity, and die.

    Progress in tobacco control policy making has occurred worldwide through advocacy campaigns involving multiple players- civil society groups, activists, academics, media and policymakers. The Framework Convention on Tobacco Control (FCTC)-the first ever global health treaty-outlines evidence-based tobacco control policies. Lebanon ratified the FCTC in 2005, but until 2011, tobacco control policies remained rudimentary and not evidence-based. Beginning in 2009, a concerted advocacy campaign was undertaken by a variety of stakeholders with the aim of accelerating the process of adopting a strong tobacco control policy. The campaign was successful, and Law 174 passed the Lebanese Parliament in August 2011. In this article, we analyse the policy making process that led to the adoption of Law 174 using Kingdon's model. The analysis relies on primary and secondary data sources including historical records of key governmental decisions, documentation of the activities of the concerted advocacy campaign and in-depth interviews with key stakeholders. We describe the opening of a window of opportunity as a result of the alignment of the problem, policy and politics streams. Furthermore, findings revealed that despite the challenge of persistent tobacco industry interference and established power relations between the industry, its allies and policymakers; policy entrepreneurs succeeded in supporting the alignment of the streams, and influencing the passage of the law. Kingdon's multiple stream approach was useful in explaining how tobacco control became an emerging policy issue at the front of the policy agenda in Lebanon.

    Weight gain has become one of the biggest issues for healthy aging in middle- and high-income countries. Self-control of emotional reward cues is an important behavioral factor for regulation of weight gain through voluntary diet control and physical activity. We tested the associations between teacher-rated self-control at ages 13 and 15 years, and measured body mass index (BMI) between ages 15 and 60-64 years, controlling for confounding factors such as affective symptoms and cognition, using 3873 study members in the Medical Research Council National Survey of Health and Development, also known as the British 1946 birth cohort. Multivariable regression analysis after adjustment for all covariates showed that lower self-control was associated with higher BMI in all measure points (P<0.05). Multilevel modeling using a cubic model showed that there was an association between self-control and BMI at 15 years in females (male: BMI=-0.00 kg m(-2) per 1 s.d. on the self-control score (95% confidence interval (CI): -0.12 to 0.11), P =0.94; female: BMI=-0.27 (-0.42 to -0.11), P<0.001). The association became stronger with age in both sexes (BMI=-0.065 (-0.082 to -0.048), P<0.001; BMI=-0.036 (-0.057 to -0.015), P<0.001). By age 60-64 years, the association between self-control and BMI in men had increased to -0.70 (-0.96 to -0.44) and -0.67 (-1.04 to -0.30) in women. Lower adolescent self-control was associated with higher BMI through the life course, and this becomes stronger with age. Investigations to test whether intervention to self-control improves obesity are recommended.

    The restructuring of the economic sectors, improvement of the business environment and, implicitly, the development of the appropriate legislative framework correspond to the main objectives of the Work Programme issued by the Government of Romania with view to fulfil the criteria imposed by the European Commission for the accession of Romania to European Union planned for the year 2007. One of the legislative package section, being under revision of the Legislative Chamber of Romania, is referring to power sector, where remarkable efforts are made in connection with energy and gas market liberalization towards 40% opening, correction applied to the thermal and electric power and gas tariffs, with a view to get fully cover of the production costs, start up of the privatisation process for some of the distribution companies and all these represent part of the main priorities of the Romanian government for the restructuring of the power sector. SN Nuclearelectrica SA - SNN SA - has as domain of its main activities the development of the nuclear program in Romania regarding: Cernavoda Unit 1 operation for production and delivery of electric power to the National Grid (since 1996), the nuclear fuel fabrication at Nuclear Fuel Plant in Pitesti, the completion and commissioning of the Cernavoda Unit 2 and start up, in the near future, of the work for Unit 3 completion. The trade activity within the power production sector using nuclear fuel is governed, due to its specific, by the rules and laws of Romania and are also subject of the international rules related to the foreign trade and, particularly to the policy of transaction of the special materials on international market. This category of special materials, named strategic materials with dual use, are under the control of the National Agency for Export Control - ANCEX, as well as other specialised and dedicated Romanian authorities, as: National Commission for the Nuclear Activities Control - CNCAN, specialized

    Water pipe tobacco smoking (WTS) is growing in popularity among U.S. young adults and is associated with health risks similar to those of cigarette smoking. The purpose of this study is to examine existing tobacco control policies (TCPs) in order to investigate how they engage WTS. A systematic synthesis of content and legal interactions among federal, state, and local TCP documents. Pennsylvania, which represents a politically and demographically diverse microcosm of the United States. No human subjects. Federal and state TCPs were retrieved via public legal repositories. Local policy searches were conducted via county/municipal Web sites, inclusive of 13 localities that had autonomous health departments or existing TCPs based on a National Cancer Institute report. Full-text TCPs were double coded within a grounded theory framework for health policy analysis. Emergent codes were used to compare and contrast policy texts and to examine legal interactions among TCPs. Examination of policy categories including youth access, use restrictions, and taxation revealed WTS as largely omitted from current TCPs. WTS was sometimes addressed as an "other" tobacco product under older TCPs, though ambiguities in language led to questionable enforceability. State preemptions have rolled back or prevented well-tailored reforms at the local level. Federal preemptions have likewise constrained state TCPs. Outdated, preempted, and unclear policies limit the extent to which TCPs engage WTS. Health advocates might target these aspects of TCP reform.

    Over the past few decades, the importance of economic research in advancing tobacco control policies has become increasingly clear. Extensive research has demonstrated that increasing tobacco taxes and prices is the single most cost-effective tobacco control measure. The research contained in this supplement adds to this evidence and provides new insights into how smokers respond to tax and price changes using the rich data on purchase behaviours, brand choices, tax avoidance and evasion, and tobacco use collected systematically and consistently across countries and over time by the International Tobacco Control (ITC) Project. The findings from this research will help inform policymakers, public health professionals, advocates, and others seeking to maximise the public health and economic benefits from higher taxes.

    Concerns have been raised about the benefits of Fe-containing supplements on infant birth weight among women with normal/high Hb levels at baseline. Thus far, no clinical trials have examined whether the effects of prenatal Fe-containing supplements on birth weight vary by maternal Hb levels. We compared the effects of Fe-folic acid (IFA) or multiple micronutrients (MMN) with folic acid (FA) supplements on birth weight among pregnant women with mild/no anaemia or high Hb levels. A double-blind randomised controlled trial was conducted in 2006-2009. In total, 18 775 pregnant women with mild/no anaemia (145 g/l) baseline Hb levels, IFA and MMN supplements increased birth weight by 91·44 (95% CI 3·37, 179·51) g and 107·63 (95% CI 21·98, 193·28) g (PHb concentration. In conclusion, the effects of Fe-containing supplements on birth weight depended on baseline Hb concentrations. The Fe-containing supplements improved birth weight in women with very high Hb levels before 20 weeks of gestation.

Optimal stochastic control based on the transition probability matrix of the underlying Markov chain has been studied extensively for probabilistic Boolean networks. Optimization is based on minimization of a cost function and a key goal of control is to reduce the steady-state probability mass of undesirable network states. Owing to computational complexity, it is difficult to apply optimal control for large networks. Results In this paper, we propose three new greedy stationary control policies by directly investigating the effects on the network long-run behavior. Similar to the recently proposed mean-first-passage-time (MFPT control policy, these policies do not depend on minimization of a cost function and avoid the computational burden of dynamic programming. They can be used to design stationary control policies that avoid the need for a user-defined cost function because they are based directly on long-run network behavior; they can be used as an alternative to dynamic programming algorithms when the latter are computationally prohibitive; and they can be used to predict the best control gene with reduced computational complexity, even when one is employing dynamic programming to derive the final control policy. We compare the performance of these three greedy control policies and the MFPT policy using randomly generated probabilistic Boolean networks and give a preliminary example for intervening in a mammalian cell cycle network. Conclusion The newly proposed control policies have better performance in general than the MFPT policy and, as indicated by the results on the mammalian cell cycle network, they can potentially serve as future gene therapeutic intervention strategies.

    Although the United States Air Force (USAF) has been a leader in efforts to reduce tobacco use among service members, tobacco continues to be a problem and initiatives to decrease tobacco use further require buy-in from leadership. We explored line leaderships' perspectives on tobacco. A diverse group of 10 senior commissioned and 10 non-commissioned personnel were interviewed. Respondents reported substantial changes in the culture of tobacco use during their years of service, from near ubiquity to restricted use areas. They also perceived mixed messages coming from the USAF, including simultaneous discouragement of and accommodations for tobacco use, and variability in policies and enforcement. Many respondents indicated that allowing tobacco use creates conflict and undermines military discipline and suggested that a tobacco-free policy would be the best way to eliminate these contradictions. Although there has been substantial movement away from a culture of tobacco in the USAF, current policies and variable enforcement of these policies create unnecessary contradictions. Establishing a tobacco-free service would resolve these issues in addition to improving the health of service members and veterans.

    Rural, tobacco-growing areas are disproportionately affected by tobacco use, secondhand smoke, and weak tobacco control policies. The purpose was to test the effects of a stage-specific, tailored policy-focused intervention on readiness for smoke-free policy, and policy outcomes in rural underserved communities. A controlled community-based trial including 37 rural counties. Data were collected annually with community advocates (n = 330) and elected officials (n = 158) in 19 intervention counties and 18 comparison counties over 5 years (average response rate = 68%). Intervention communities received policy development strategies from community advisors tailored to their stage of readiness and designed to build capacity, build demand, and translate and disseminate science. Policy outcomes were tracked over 5 years. Communities receiving the stage-specific, tailored intervention had higher overall community readiness scores and better policy outcomes than the comparison counties, controlling for county-level smoking rate, population size, and education. Nearly one-third of the intervention counties adopted smoke-free laws covering restaurants, bars, and all workplaces compared to none of the comparison counties. The stage-specific, tailored policy-focused intervention acted as a value-added resource to local smoke-free campaigns by promoting readiness for policy, as well as actual policy change in rural communities. Although actual policy change and percent covered by the policies were modest, these areas need additional resources and efforts to build capacity, build demand, and translate and disseminate science in order to accelerate smoke-free policy change and reduce the enormous toll from tobacco in these high-risk communities. © 2014 National Rural Health Association.

    Although valuable, national opinion surveys on alcohol policy may be less informative for policy development at the local level. Using samples of adult residents in 2 college communities, the present study: (1) measured public support for local alcohol control policies to stem underage drinking and alcohol overservice in on-premise outlets, (2) assessed residents' opinions regarding neighborhood problems, and (3) identified factors associated with strong policy support. We administered random-sample telephone surveys to residents aged 21 years and older in college communities located in Community 1 (N = 501; mean age = 57.4 years, SD = 14.7) and Community 2 (N = 505; mean age = 56.0 years, SD = 15.2). The response rates were typical of telephone surveys (Community 1: 33.5%; Community 2: 29.9%). We assessed support for 16 alcohol control policies and the occurrence of specific types of neighborhood incidents (e.g., witnessing intoxicated people). We used multiple regression analyses to determine factors associated with policy support. Residents in Community 1 reported significantly higher weekly alcohol use, a greater number of witnessed neighborhood incidents, and a higher level of perceived neighborhood problems than did residents in Community 2. Residents in Community 1 perceived local alcohol control policies and their enforcement to be significantly stricter. Overall, policy support was high and did not differ between the communities. In both communities, higher policy support was significantly associated with being female, being older, less weekly alcohol use, and lower perceived strictness of alcohol control policies and enforcement. It is important for campus officials and community leaders to be aware of and publicize favorable public opinion when advocating for policy change, especially at the local level. Information on residents' perceptions of the neighborhood issues they face can also inform local policy and enforcement efforts.

    Full Text Available OBJECTIVE: We investigated the association between a child's birth order and emergency room (ER visits and hospital admissions following 2-,4-,6- and 12-month pediatric vaccinations. METHODS: We included all children born in Ontario between April 1(st, 2006 and March 31(st, 2009 who received a qualifying vaccination. We identified vaccinations, ER visits and admissions using health administrative data housed at the Institute for Clinical Evaluative Sciences. We used the self-controlled case series design to compare the relative incidence (RI of events among 1(st-born and later-born children using relative incidence ratios (RIR. RESULTS: For the 2-month vaccination, the RIR for 1(st-borns versus later-born children was 1.37 (95% CI: 1.19-1.57, which translates to 112 additional events/100,000 vaccinated. For the 4-month vaccination, the RIR for 1(st-borns vs. later-borns was 1.70 (95% CI: 1.45-1.99, representing 157 additional events/100,000 vaccinated. At 6 months, the RIR for 1(st vs. later-borns was 1.27 (95% CI: 1.09-1.48, or 77 excess events/100,000 vaccinated. At the 12-month vaccination, the RIR was 1.11 (95% CI: 1.02-1.21, or 249 excess events/100,000 vaccinated. CONCLUSIONS: Birth order is associated with increased incidence of ER visits and hospitalizations following vaccination in infancy. 1(st-born children had significantly higher relative incidence of events compared to later-born children.

    This article presents an exploration of qualitative evidence on the relationship between birth control and abstinence from an oral history project, which interviewed middle and working-class English men and women, who had married between the late 1920s and the early 1950s. Among the working classes the assumption that men were responsible for birth control choices and the disadvantages that contraceptive methods of all types posed, combined with the fear of pregnancy, acted as a disincentive to have sex and resulted in forms of partial abstinence. Among the middle classes, women had much more access to birth control information and as a consequence a greater range of methods was used, including more female methods. However, the reluctance of couples to discuss sexual matters, and some continued preference for male methods meant that while condoms were the most regularly used middle-class male method, both withdrawal and abstinence were also in evidence. Moreover, although partners were more likely to discuss birth control at the start of their marriages, they were less likely to agree that contraception was a male responsibility and there was greater potential for conflict over contraceptive methods, not infrequently resulting in abstinence. The evidence suggests that sexual and contraceptive practices in marriages in England at the end of the secular fertility decline do not present a picture which straightforwardly correlates with the assumptions represented by the popular thesis that this period of increased fertility control was closely associated with the rise of companionate marriage.

    This paper estimates an off-policy integral reinforcement learning (IRL) algorithm to obtain the optimal tracking control of unknown chaotic systems. Off-policy IRL can learn the solution of the HJB equation from the system data generated by an arbitrary control. Moreover, off-policy IRL can be regarded as a direct learning method, which avoids the identification of system dynamics. In this paper, the performance index function is first given based on the system tracking error and control error. For solving the Hamilton–Jacobi–Bellman (HJB) equation, an off-policy IRL algorithm is proposed. It is proven that the iterative control makes the tracking error system asymptotically stable, and the iterative performance index function is convergent. Simulation study demonstrates the effectiveness of the developed tracking control method. (paper)

    Dietary intake of nitrates, nitrites, and nitrosamines can increase the endogenous formation of N-nitroso compounds in the stomach. Results from animal studies suggest that these compounds might be teratogenic. We examined the relationship between maternal dietary intake of nitrates, nitrites (including plant and animal sources as separate groups), and nitrosamines and several types of birth defects in offspring. For this population-based case-control study, data from a 58-question food frequency questionnaire, adapted from the short Willett Food Frequency Questionnaire and administered as part of the National Birth Defects Prevention Study (NBDPS), were used to estimate daily intake of dietary nitrates, nitrites, and nitrosamines in a sample of 6544 mothers of infants with neural tube defects (NTD)s, oral clefts (OC)s, or limb deficiencies (LD)s and 6807 mothers of unaffected control infants. Total daily intake of these compounds was divided into quartiles based on the control mother distributions. Odds ratios (OR)s and 95% confidence intervals (CI)s were estimated using logistic regression; estimates were adjusted for maternal daily caloric intake, maternal race-ethnicity, education, dietary folate intake, high fat diet (>30% of calories from fat), and state of residence. While some unadjusted ORs for NTDS had 95% (CI)s that excluded the null value, none remained significant after adjustment for covariates, and the effect sizes were small (adjusted odds ratios [aOR]<1.12). Similar results were found for OCs and LDs with the exception of animal nitrites and cleft lip with/without cleft palate (aORs and CIs for quartile 4 compared to quartile 1 =1.24; CI=1.05-1.48), animal nitrites and cleft lip (4th quartile aOR=1.32; CI=1.01-1.72), and total nitrite and intercalary LD (4th quartile aOR=4.70; CI=1.23-17.93). Overall, odds of NTDs, OCs or LDs did not appear to be significantly associated with estimated dietary intake of nitrate, nitrite, and nitrosamines.

    Dysphonia is a potential complication of prematurity. Preterm children may sustain iatrogenic laryngeal damage from medical intervention in the neonatal period, and further, adopt compensatory, maladaptive voicing behaviors. This pilot study aimed to evaluate the effects of a voice therapy protocol on voice quality in school-aged, very preterm (VP) children. Twenty-seven VP children with dysphonia were randomized to an immediate intervention group (n = 7) or a delayed-intervention, waiting list control group (n = 14). Following analysis of these data, a secondary analysis was conducted on the pooled intervention data (n = 21). Six participants did not complete the trial. Change to voice quality was measured via pre- and posttreatment assessments using the Consensus Auditory Perceptual Evaluation of Voice. The intervention group did not demonstrate statistically significant improvements in voice quality, whereas this was observed in the control group (P = 0.026). However, when intervention data were pooled including both the immediate and delayed groups following intervention, dysphonia severity was significantly lower (P = 0.026) in the treatment group. Dysphonia in most VP children in this cohort was persistent. These pilot data indicate that some participants experienced acceptable voice outcomes on spontaneous recovery, whereas others demonstrated a response to behavioral intervention. Further research is needed to identify the facilitators of and barriers to intervention success, and to predict those who may experience spontaneous recovery. Copyright © 2017 The Voice Foundation.

    2013-06-01

    We examined the associations among school-based obesity policies, social capital, and adolescents' self-reported weight control behaviors, focusing on how the collective roles of community and adopted policies affect gender groups differently. We estimated state-level ecologic models using 1-way random effects seemingly unrelated regressions derived from panel data for 43 states from 1991 to 2009, which we obtained from the Centers for Disease Control and Prevention's Youth Risk Behavior Surveillance System. We used multiplicative interaction terms to assess how social capital moderates the effects of school-based obesity policies. School-based obesity policies in active communities were mixed in improving weight control behaviors. They increased both healthy and unhealthy weight control behaviors among boys but did not increase healthy weight control behaviors among girls. Social capital is an important contextual factor that conditions policy effectiveness in large contexts. Heterogeneous behavioral responses are associated with both school-based obesity policies and social capital. Building social capital and developing policy programs to balance outcomes for both gender groups may be challenging in managing childhood obesity.

  10. Intervention in gene regulatory networks via a stationary mean-first-passage-time control policy.

    2008-10-01

    A prime objective of modeling genetic regulatory networks is the identification of potential targets for therapeutic intervention. To date, optimal stochastic intervention has been studied in the context of probabilistic Boolean networks, with the control policy based on the transition probability matrix of the associated Markov chain and dynamic programming used to find optimal control policies. Dynamical programming algorithms are problematic owing to their high computational complexity. Two additional computationally burdensome issues that arise are the potential for controlling the network and identifying the best gene for intervention. This paper proposes an algorithm based on mean first-passage time that assigns a stationary control policy for each gene candidate. It serves as an approximation to an optimal control policy and, owing to its reduced computational complexity, can be used to predict the best control gene. Once the best control gene is identified, one can derive an optimal policy or simply utilize the approximate policy for this gene when the network size precludes a direct application of dynamic programming algorithms. A salient point is that the proposed algorithm can be model-free. It can be directly designed from time-course data without having to infer the transition probability matrix of the network.

  11. The birth of quantum networks: merging remote entanglement with local multi-qubit control

    Science.gov (United States)

    Hanson, Ronald

    The realization of a highly connected network of qubit registers is a central challenge for quantum information processing and long-distance quantum communication. Diamond spins associated with NV centers are promising building blocks for such a network: they combine a coherent spin-photon interface that has already enabled creation of spin-spin entanglement over 1km with a local register of robust and well-controlled nuclear spin qubits for information processing and error correction. We are now entering a new research stage in which we can exploit these features simultaneously and build multi-qubit networks. I will present our latest results towards the first of such experiments: entanglement distillation between remote quantum network nodes. Finally, I will discuss the challenges and opportunities ahead on the road to large-scale networks of qubit registers for quantum computation and communication.

    Evaluation of the commonly used laboratory and clinical parameters of the newborn shortly after birth. Check thresholds acidemia, and in relation to the method of termination of pregnancy. Retrospective epidemiological study. Department of Obstetrics and Gynecology, University Hospital, Olomouc. Of the 26,869 children born in the years 2000 to 2013 Inclusion criteria (complete clinical and laboratory findings after birth) fulfill 23,471 (87.4%) neonates. Methods for evaluation of newborns included Apgar score calculation and arterial umbilical cord blood pH and lactate analysis. A total of 0.7% (157) of the neonates had severe acidosis pH below 7.00 arterial umbilical cord blood, its prevalence varies annually between 0.1 to 1.1%. Cutoff lactate in relation to pH reserves. Operating cesarean births in particular accounts for more than half of those with worse clinical findings Apgar and pH <7.00, but only 30% supratreshold lactate values. Also worse clinical evaluation after caesarean section is not in accordance with the laboratory findings. Vaginal surgery, especially forceps have a significant share of severe acidosis than cesarean, regardless of their frequency. Risk factor of forceps to pH less 7.00,OR = 9.28 (5.39 -15.77), P = 0.0000000, while caesarean to pH less 7,00 had OR = 1.52 (1.08 to 2.14), P = 0.01408156. The results obtained confirm that acidosis after birth is quite common, although they may not have response on the clinical condition of the newborn after birth. Evaluation of Apgar is little objective for the detection of hypoxia during birth and is influenced by the immaturity of newborn and method of delivery. Lactate levels may contribute to an objective assessment of hypoxia during birth. Values above 6.3 mmol/l can be considered an important indicator of newborn acidosis and birth hypoxia.

    To analyze the associations between birth weight and overweight/obesity among children. A total of 8 267 twin pairs younger than 18 years old from the Chinese National Twin Registry were included in the study. Associations between birth weight, childhood BMI and overweight/obesity were explored by this co-twin control study. After adjusting for sex and zygosity, when birth weight had an increase of 0.5 kg per fold, the OR values for overweight and obesity were 1.87(95%CI: 1.40-2.48) for 2-6 year olds, 1.69 (95%CI: 1.16-2.46) for 6-12 year olds and 1.28 (95%CI: 0.80-2.07) for 12-18 year olds. from the stratified analysis in the 2-6 year-olds, statistically significant differences were seen. When birth weight increased 0.5 kg per fold, the risk of overweight and obesity increased by 0.87 times among the dizygotic twins, more than that of the monozygotic twins (OR=1.86, 95%CI:1.24-2.81). The risk for male twins was 1.12 times higher than that of female twins (OR=1.65, 95%CI:1.11-2.44). Birth weight seemed associated with overweight and obesity for kids at early childhood or at age for schools. However, guidance on the implementation of public health interventions is still needed on these children.

    Arsenic is a highly dangerous metal that has been linked to a number of adverse health effects in both adults and children, including birth defects. Yet few epidemiologic studies have examined the relationship between arsenic levels in the soil and the risk of birth defects. The purpose of the authors' study was to examine this association among people exposed to environmental pollution in a developed area of China. The authors used global positioning system to locate the coordinates of 80 villages in 40 towns for soil sampling. Soil samples were analyzed for arsenic content. Logistic regression was used to investigate the relationship between exposure to arsenic and birth defects, controlling for potentially confounding factors. The authors found that exposure to arsenic in any amount increased the risk of birth defects. The positive association found between arsenic exposure and birth defects warrants further study, and future large-scale population-based studies are needed with an emphasis on individual-level exposure and confounding variables.

  17. Postnational or National Europe? European Asylum Policies and Immigration Controls

    Full Text Available The paper deals with the theories of the transformation of the modern functions of the nation state and the immigrant membership associated with the (legally defined status of community members exemplified by asylum policies. In the process, two fundamental approaches to the issue are distinguished: the first one emphasizing changes in the institution of the traditional national citizenship and competences of the nation state, while stressing a predominantly national character of the institution of citizenship, and the second one, which emphasizes the transformation of traditional citizenships, stressing the weakening of the role of the nation state. Therefore, in the latter case, there is increasingly more talk about postnationalism, which is a term denoting the transformation of the substantive aspects of citizenship in the EU countries. The mentioned theoretical approaches are applied to three groups of issues. First, the impact of the EU on the processes of the globalisation of the rights of asylum migrants are examined. Second, the paper works out the details of the way of formulating the policy of asylum membership in the EU member states. Third, the question of whether universal postnational inclusion of asylum migrants is at work in the EU member states, or whether the status of this group of immigrants should be found within the limits of the traditional theory of state membership and national sovereignty is addressed

    There has been much variation between European countries in the development of tobacco control policy. Not much is known about the factors that shape this variation. This study aimed to assess the role of political factors in tobacco control policy development. We used data from 11 European countries from 1996 to 2010. Multilevel regression modelling was used to investigate associations between the Tobacco Control Scale (TCS) and indicators of left-wing government and government effectiveness (policy formulation, implementation and enforcement), with control for confounders. An association was found between left-wing government and TCS over the period 1996-2003, but not over the whole period. The association between government effectiveness and TCS was significant and negative over the whole period, but positive between 2001 and 2005. Residual analysis showed that TCS scores from 2002 onwards were higher than expected based on the political factors. Associations varied among the five subscales of the TCS. The results suggest that, on the whole, national political factors have had only a minor influence on the large variations in tobacco control policy development in Europe over the last 15 years. However, there are indications that left-wing governments were important for early adoption of tobacco control policy, and high government effectiveness was important in the phase of adopting innovative policies. However, since 2002, with the advent of international treaties, the influence of national politics has diminished. © The Author 2014.

    Childhood brain tumors (CBT) are the leading cause of cancer death in children, yet their causes are largely known. This study investigated the association between maternal and birth characteristics and risk of CBT. Cases families were recruited from all 10 Australian pediatric oncology centers between 2005 and 2010. Control families were recruited via random-digit dialing, frequency matched to cases on the basis of child's age, sex, and State of residence. Maternal and birth characteristics of children were ascertained by questionnaires. Odds ratios (ORs) and 95% confidence intervals (CI) were estimated using unconditional logistic regression, adjusting for relevant confounders. For this analysis, data on 319 case children and 1,079 control children were available. No association was found between risk of CBT and birth weight, fetal growth, birth order, gestational age, or maternal body mass index. The ORs for inadequate and excessive maternal gestational weight gain (GWG) (Institute of Medicine 2009 guidelines) were 1.8 (95% CI 1.2-2.6) and 1.4 (95% CI 1.0-2.1), respectively; similar findings for GWG were seen across categories of child's age, fetal growth, maternal body mass index and height, maternal smoking, and parental education. Risk of low grade glioma appeared increased with preterm birth (OR 1.6 (95% CI 0.8-3.1) and admission to neonatal intensive care (NICU) for >2 days (OR 1.7, 95% CI 0.9-3.6). We found little evidence of associations between risk of CBT and most birth characteristics. The associations we observed with GWG, prematurity and NICU admission require corroboration in other studies. © 2013 Wiley Periodicals, Inc.

This model combines correlation-based learning using input correlation learning (ICO learning) and reward-based learning using continuous actor–critic reinforcement...... learning (RL), thereby working as a dual learner system. The model performance is evaluated by simulations of a cart-pole system as a dynamic motion control problem and a mobile robot system as a goal-directed behavior control problem. Results show that the model can strongly improve pole balancing control...... policy, i.e., it allows the controller to learn stabilizing the pole in the largest domain of initial conditions compared to the results obtained when using a single learning mechanism. This model can also find a successful control policy for goal-directed behavior, i.e., the robot can effectively learn...

  4. Policy Innovation and Policy Pathways: Tuberculosis Control in Sri Lanka, 1948-1990.

    Jones, Margaret

    2016-10-01

    This paper, based on World Health Organization and Sri Lankan sources, examines the attempts to control tuberculosis in Sri Lanka from independence in 1948. It focuses particularly on the attempt in 1966 to implement a World Health Organization model of community-orientated tuberculosis control that sought to establish a horizontally structured programme through the integration of control into the general health services. The objective was to create a cost- effective method of control that relied on a simple bacteriological test for case finding and for treatment at the nearest health facility that would take case detection and treatment to the rural periphery where specialist services were lacking. In the late 1940s and early 1950s, Sri Lanka had already established a specialist control programme composed of chest clinics, mass X-ray, inpatient and domiciliary treatment, and social assistance for sufferers. This programme had both reduced mortality and enhanced awareness of the disease. This paper exposes the obstacles presented in trying to impose the World Health Organization's internationally devised model onto the existing structure of tuberculosis control already operating in Sri Lanka. One significant hindrance to the WHO approach was lack of resources but, equally important, was the existing medical culture that militated against its acceptance.

    Early nutrition may affect the risk of celiac disease. We investigated whether amount of gluten in diet until 2 years of age increases risk for celiac disease. We performed a 1-to-3 nested case-control study of 146 cases, resulting in 436 case-control pairs matched for sex, birth year, and HLA genotype generated from Swedish children at genetic risk for celiac disease. Newborns were annually screened for tissue transglutaminase autoantibodies (tTGA). If tested tTGA positive, time point of seroconversion was determined from frozen serum samples taken every 3 months. Celiac disease was confirmed by intestinal biopsies. Gluten intake was calculated from 3-day food records collected at ages 9, 12, 18 and 24 months. Odds ratios (OR) were calculated through conditional logistic regression. Breastfeeding duration (median, 32 wk) and age at first introduction to gluten (median, 22 wk) did not differ between cases and tTGA-negative controls. At the visit before tTGA seroconversion, cases reported a larger intake of gluten than controls (OR, 1.28; 95% confidence interval [CI], 1.13-1.46; P = .0002). More cases than controls were found in the upper third tertile (ie, >5.0 g/d) before they tested positive for tTGA seroconversion than controls (OR, 2.65; 95% CI, 1.70-4.13; P children homozygous for DR3-DQ2 (OR, 3.19; 95% CI, 1.61-6.30; P = .001), heterozygous for DR3-DQ2 (OR, 2.24; 95% CI, 1.08-4.62; P = .030), and for children not carrying DR3-DQ2 (OR, 2.43; 95% CI, 0.90-6.54; P = .079). The amount of gluten consumed until 2 years of age increases the risk of celiac disease at least 2-fold in genetically susceptible children. These findings may be taken into account for future infant feeding recommendations. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

  6. Soviet declaratory policy regarding the controllability of escalation

    1991-01-01

    Three variables were examined for their affect on Soviet views regarding the controllability of escalation. The first was bureaucratic affiliation. It was hypothesized that individuals affiliated with groups which directly controlled weapons would be more likely to support the controllability of escalation than those who were members of groups which did not control weapons. This hypothesis could not be rejected. The second variable was a commentator's rank. It was hypothesized that rank would act in two ways: (1) ideas regarding controlled escalation would appear at lower ranks first; and (2) unique views would be produced by specialized ranks within groups. The rank hypothesis could not be rejected. Certain escalation themes appeared to be presented first by military and civilian writers before being presented by the political leadership. The third variable, image of the West, did not appear to function as theorized. It was hypothesized that hard images of the West would be associated with the rejection of controlled escalation, whereas soft images would be associated with positions suggesting that escalation was controlled through joint US-Soviet cooperation

  7. Influence of export control policy on the competitiveness of machine tool producing organizations

    Science.gov (United States)

    Ahrstrom, Jeffrey D.

    The possible influence of export control policies on producers of export controlled machine tools is examined in this quantitative study. International market competitiveness theories hold that market controlling policies such as export control regulations may influence an organization's ability to compete (Burris, 2010). Differences in domestic application of export control policy on machine tool exports may impose throttling effects on the competitiveness of participating firms (Freedenberg, 2010). Commodity shipments from Japan, Germany, and the United States to the Russian market will be examined using descriptive statistics; gravity modeling of these specific markets provides a foundation for comparison to actual shipment data; and industry participant responses to a user developed survey will provide additional data for analysis using a Kruskal-Wallis one-way analysis of variance. There is scarce academic research data on the topic of export control effects within the machine tool industry. Research results may be of interest to industry leadership in market participation decisions, advocacy arguments, and strategic planning. Industry advocates and export policy decision makers could find data of interest in supporting positions for or against modifications of export control policies.

    Birth defects are a global public health problem because of their large contribution to infant mortalities and disabilities. It is estimated that 4%-6% of Chinese newborns are affected by birth defects every year. Surveillance is a basic approach to understanding the occurrence and associated factors of birth defects. The Ministry of Health of China initiated a national hospital-based birth defects monitoring system 20 years ago. Nearly every province in this country has established its own surveillance system in the past. The authors reviewed the result of the monitoring system at different administrative levels in China. Available publications on the surveillance of birth defects and data from national and provincial birth defects surveillance systems were reviewed to evaluate the effectiveness of the surveillance systems. According to the 2009 data, the national hospital-based birth defects surveillance system monitored over 1.3 million births, which accounted for more than 8% of births in China. In addition, 30 provincial hospital-based surveillance programs covered a birth population of more than 3.6 million (22% of births in China). Great achievements have been made in terms of case ascertainment, data quality control, and online reporting. But the surveillance systems in China still have some limitations. A short ascertainment period may miss some internal anomalies, inherited metabolic diseases, and malformed fetus aborted before the 28th gestational week. Discrepancies in antenatal or postnatal diagnosis of birth defects between surveillance institutes may affect the detection rate and introduce biases. Absence of baseline data and lack of integrated database systems limit the application of surveillance data to etiological studies and affect the process of decision-making. The surveillance system for birth defects is prerequisite to propose, conduct and assess any interventions for the disease. To meet the need of study and prevention of birth defects

    We aimed to assess whether a twice daily assisted exercise interventional program will have a greater effect on bone strength compared to a once daily intervention or no intervention in very low birth weight (VLBW) preterm infants. Thirty-four very VLBW preterm infants (mean BW 1217 ± 55 g and mean gestational age 28.6 ± 1.1 weeks) were randomly assigned into one of three study groups: twice daily interventions (n = 13), a once daily intervention (n = 11), and no intervention (control, n = 10). The intervention was initiated at a mean of 8 ± 2.4 days of life and continued for 4 weeks. It included passive extension and flexion range-of-motion exercise of the upper and lower extremities. Bone strength was measured at enrollment and after 2 and 4 weeks using quantitative ultrasound of tibial bone speed of sound (SOS, Sunlight Omnisense™). At enrollment, the mean bone SOS was comparable between the twice daily interventions, once daily intervention and control groups (2918 ± 78, 2943 ± 119, and 2910 ± 48 m/s, respectively). As expected, the bone SOS declined in all groups during the study period (-23.6 ± 24, -68.8 ± 28, and -115.8 ± 30 m/s, respectively, p strength in the twice daily intervention group (p = 0.03). A twice daily intervention program of assisted range-of-motion exercise attenuates the decrease in bone strength and may decrease the risk of osteopenia and future fractures in VLBW preterm infants.

    Evidence has suggested that periodontal disease is associated with an increased risk of various adverse pregnancy and birth outcomes. However, several large clinical randomized controlled trials failed to demonstrate periodontal therapy during pregnancy reduced the incidence of adverse pregnancy and birth outcomes. It has been suggested that the pre-conception period may be an optimal period for periodontal disease treatment rather than during pregnancy. To date, no randomized controlled trial (RCT) has examined if treating periodontal disease before pregnancy reduces adverse birth outcomes. This study aims to examine if the pre-conception treatment of periodontal disease will lead to improved periodontal status during late pregnancy and subsequent birth outcomes. A sample of 470 (235 in each arm of the study) pre-conception women who plan to conceive within one year and with periodontal disease will be recruited for the study. All participants will be randomly allocated to the intervention or control group. The intervention group will receive free therapy including dental scaling and root planning (the standard therapy), supragingival prophylaxis, and oral hygiene education. The control group will only receive supragingival prophylaxis and oral hygiene education. Women will be followed throughout their pregnancy and then to childbirth. The main outcomes include periodontal disease status in late pregnancy and birth outcomes measured such as mean birth weight (grams), and mean gestational age (weeks). Periodontal disease will be diagnosed through a dental examination by measuring probing depth, clinical attachment loss and percentage of bleeding on probing (BOP) between gestational age of 32 and 36 weeks. Local and systemic inflammatory mediators are also included as main outcomes. This will be the first RCT to test whether treating periodontal disease among pre-conception women reduces periodontal disease during pregnancy and prevents adverse birth outcomes. If

    2014-01-01

    HTR-PM is an HTR demonstration plant with a structure of two modules feeding one steam turbine. Compared with the structure of one single reactor feeding one turbine, there are more devices shared between these two modules. When they are operated, the shared components are prone to introduce collisions or even logical deadlocks for different technical processes. The future commercial HTR-PM plants are supposed to comprise more modules for a larger turbine, thus the collision problem introduced by the shared components may become severer. Therefore, how to design suitable policies in the distributed control system (DCS) to relieve the collisions during using these shared devices is a new and also a very important problem. In this paper, the classifications of the shared devices are first addressed, and then how to identify the shared objects of an NPP is proposed. Furthermore, a general model for the control logic design is proposed, taking into consideration the collision avoidance, time delay and fairness. The example of how to apply the schemes to relieve the conflicts and deadlocks in the processes of using the shared devices in fuel element cycling system is illustrated. (author)

    Methionine synthase (MTR) is required for the conversion of homocysteine (hcy) to methionine in the one-carbon metabolic pathway. Previous studies investigating a common MTR 2756A>G polymorphism as a maternal risk factor for the birth of a child with Down syndrome (DS) are conflicting and limited by small case-control cohorts, and its contribution to circulating hcy levels is still debated. We performed a large case-control study and a meta-analysis of the literature to further address the role of MTR 2756A>G as a maternal risk factor for the birth of a child with DS. 286 mothers of a DS child (MDS) and 305 control mothers of Italian origin were included in the case-control study. Genotyping was performed by means of PCR/RFLP technique. Data on circulating levels of hcy, folates, and vitamin B12 were available for 189 MDS and 194 control mothers. The meta analysis of previous and present data involved a total of 8 studies (1,171 MDS and 1,402 control mothers). Both the case-control study and the meta-analysis showed no association of MTR 2756A>G with the maternal risk of birth of a child with DS (OR = 1.15; 95 % CI 0.85-1.55, and OR = 1.08; 95 % CI 0.93-1.25, respectively), even after stratification of the overall data available for the meta-analysis into ethnic groups. No association of the studied polymorphism with circulating levels of hcy, folates, and vitamin B12 was observed. Present data do not support a role for MTR 2756A>G as independent maternal risk factor for a DS birth.

    Full Text Available Abstract Background Studies in adult intensive care have highlighted the importance of insulin and improved glucose control on survival, with 32% reduction in mortality, 22% reduction in intensive care stay and halving of the incidence of bacteraemia. Very low birth weight infants requiring intensive care also have relative insulin deficiency often leading to hyperglycaemia during the first week of life. The physiological influences on insulin secretion and sensitivity, and the potential importance of glucose control at this time are not well established. However there is increasing evidence that the early postnatal period is critical for pancreatic development. At this time a complex set of signals appears to influence pancreatic development and β cell survival. This has implications both in terms of acute glucose control but also relative insulin deficiency is likely to play a role in poor postnatal growth, which has been associated with later motor and cognitive impairment, and fewer β cells are linked to risk of type 2 diabetes later in life.

    2009-09-01

    Full Text Available Investment in disease control should be targeted to critical points that provide the greatest benefit to the livelihoods of livestock-dependent stakeholders. Risk-based targeting should balance the impacts of diseases against the feasibility of their control. This requires sensitive and specific surveillance systems that provide representative overviews of the animal health situation for accurate assessment of disease impact and transmission patterns. Assessment of impact should include household and market effects. The key in surveillance is involving livestock owners using active methods that ensure their disease priorities are addressed. Epidemiological targeting of interventions to critical points in disease transmission cycles should be done to obtain maximal disease reduction. Interventions should be delivered in full partnership with both private and community-based stakeholders to assure high uptake and sustainability. In developing countries, approaches such as participatory disease surveillance and community-based animal health programs have been effective and comply with international animal health standards.

We show...... semantics is described normatively using natural language. The use of English text in standardisation leads to the risk of misinterpretation and ambiguity. In order to avoid this drawback, we define an abstract syntax of XACML 3.0 and a formal XACML semantics. Second, we propose a logic-based XACML analysis...... framework using Answer Set Programming (ASP). With ASP we model an XACML PDP that loads XACML policies and evaluates XACML requests against these policies.

  19. Managing ISR sharing policies at the network edge using Controlled English

    2013-05-01

    In domains such as emergency response and military operations the sharing of Intelligence, Surveillance and Reconnaissance (ISR) assets among different coalition partners is regulated through policies. Traditionally, poli­ cies are created at the center of a coalitions network by high-level decision makers and expressed in low-level policy languages (e.g. Common Information Model SPL) by technical personnel, which makes them difficult to be understood by non-technical users at the edge of the network. Moreover, policies must often be modified by negotiation among coalition partners, typically in rapid response to the changing operational situation. Com­ monly, the users who must cope first with situational changes are those on the edge, so it would be very effective if they were able to create and negotiate policies themselves. We investigate the use of Controlled English (CE) as a means to define a policy representation that is both human-friendly and machine processable. We show how a CE model can capture a variety of policy types, including those based on a traditional asset ownership model, and those defining team-based asset sharing across a coalition. The use of CE is intended to benefit coalition networks by bridging the gap between technical and non-technical users in terms of policy creation and negoti­ ation, while at the same time being directly processable by a policy-checking system without transformation to any other technical representation.

    In this secondary analysis of data from a double-blind randomized controlled trial carried out in northern China, we aimed to assess the effect of prenatal supplementation with multiple micronutrients (MMN) or iron + folic acid (IFA), versus folic acid (FA) alone, on risk of spontaneous preterm birth (SPB) and the impact of supplementation timing on SPB. A total of 18,775 nulliparous pregnant women enrolled between 2006 and 2009 were randomly assigned to receive daily FA, IFA, or MMN from the period before 20 weeks' gestation to delivery. The incidences of SPB for women consuming FA, IFA, and MMN were 5.7%, 5.6% and 5.1%, respectively. Compared with women given FA, the relative risks of SPB for those using MMN and IFA were 0.99 (95% confidence interval: 0.85, 1.16) and 0.89 (95% confidence interval: 0.79, 1.05), respectively. SPB incidence in women who started consuming FA, IFA, and MMN before the 12th week of gestation (4.6%, 4.2%, and 3.9%, respectively) was significantly reduced compared with starting supplement use on or after the 12th gestational week (6.9%, 7.2%, and 6.4%, respectively). Starting use of FA, IFA, or MMN supplements before the 12th week of gestation produced a 41%-45% reduction in risk of SPB. Early prenatal enrollment and micronutrient use during the first trimester of pregnancy appeared to be of particular importance for prevention of SPB, regardless of supplement group. © The Author(s) 2017.

    To compare academic and cognitive ability, attention, attitudes, and behavior of extremely low birth weight (ELBW) adolescents who are free of major impairments at 17 years of age with term-born control subjects. Between January 31, 1981, and February 9, 1986, 250 infants of Teens with major sensorimotor handicaps and/or IQ teens, 53 (67%) were assessed at 17.3 (16.3-19.7) years (birth weight: 720 [520-800 g]; gestation: 26 [23-29] weeks). The test battery screened the following areas: cognitive (Wechsler Intelligence Scale for Adults Third Edition, 3 subtests), academic (Wide Range Achievement Test-3), attention (Connors' Continuous Performance Task), self-report (Harter Self-Perception Profile for Adolescents; Job Search Attitude Inventory), and parent report (Child Behavior Check List). A comparison group of term born control subjects (n = 31) were also assessed (birth weight: 3506 [3068-4196] g; gestation: 40 [39-42] weeks) at age 17.8 (16.5-19.0) years. Multivariate analysis of variance (group x gender) was conducted for each domain (cognitive, academic, self-report, and parent report). The ELBW group showed lower cognitive scores (vocabulary, block design, and digit symbol) and academic skills (reading and arithmetic) compared with control subjects, with no gender differences. There were no differences in attention between the 2 groups using a repetitive computer task. ELBW teens reported lower scholastic, athletic, job competence, and romantic confidence and viewed themselves as more likely to need help from others in finding a job. In the behavioral domain, parents reported their ELBW teens to display more internalizing, more externalizing, and more total problems than the control teens, with ELBW boys showing more problems. ELBW teens showed a higher percentage of clinically significant behavior problems than control subjects. In a provincial cohort of unimpaired survivors of birth weight < or =800 g, psychosocial and educational vulnerabilities persist

  10. Technology in the policy process - controlling nuclear power

    International Nuclear Information System (INIS)

    Collingridge, D.

    1983-01-01

    The discussion in this book is built around nuclear power. The technology of nuclear power is shown to have features which make it inflexible in the sense that, once built, it is difficult and expensive to control. If inflexible technology is to be avoided, it is crucially important to be able to identify this failing at an early stage in the technology's development, before it has acquired an immunity to political control. Again, this problem is approached through the example of nuclear power, in particular the breeder reactor. The breeder is shown to be even less flexible than today's nuclear technology, because it will have higher capital costs, be of greater capital intensity, longer lead time, larger unit size, and will require more infrastructure for its operation. If this is developed, the breeder will be even less open to political control than the nuclear plant of the present. To put it another way, its planning will be even more open to errors and whatever errors are made will be even more costly than for existing nuclear technology. It is therefore even less of a socially and economically acceptable technology than today's nuclear power. (author)

  11. Air Pollution Prevention and Control Policy in China.

    With rapid urbanization and development of transport infrastructure, air pollution caused by multiple-pollutant emissions and vehicle exhaust has been aggravated year by year in China. In order to improve air quality, the Chinese authorities have taken a series of actions to control air pollution emission load within a permissible range. However, although China has made positive progress on tackling air pollution, these actions have not kept up with its economy growth and fossil-fuel use. The traditional single-pollutant approach is far from enough in China now, and in the near future, air pollution control strategies should move in the direction of the multiple-pollutant approach. In addition, undesirable air quality is usually linked with the combination of high emissions and adverse weather conditions. However, few studies have been done on the influence of climate change on atmospheric chemistry in the global perspective. Available evidence suggested that climate change is likely to exacerbate certain kinds of air pollutants including ozone and smoke from wildfires. This has become a major public health problem because the interactions of global climate change, urban heat islands, and air pollution have adverse effects on human health. In this chapter, we first review the past and current circumstances of China's responses to air pollution. Then we discuss the control challenges and future options for a better air quality in China. Finally, we begin to unravel links between air pollution and climate change, providing new opportunities for integrated research and actions in China.

    The molecular mechanisms controlling human birth timing at term, or resulting in preterm birth, have been the focus of considerable investigation, but limited insights have been gained over the past 50 years. In part, these processes have remained elusive because of divergence in reproductive strategies and physiology shown by model organisms, making extrapolation to humans uncertain. Here, we summarize the evolution of progesterone signaling and variation in pregnancy maintenance and termination. We use this comparative physiology to support the hypothesis that selective pressure on genomic loci involved in the timing of parturition have shaped human birth timing, and that these loci can be identified with comparative genomic strategies. Previous limitations imposed by divergence of mechanisms provide an important new opportunity to elucidate fundamental pathways of parturition control through increasing availability of sequenced genomes and associated reproductive physiology characteristics across diverse organisms.

  13. A CoD-based stationary control policy for intervening in large gene regulatory networks.

    2011-10-18

    One of the most important goals of the mathematical modeling of gene regulatory networks is to alter their behavior toward desirable phenotypes. Therapeutic techniques are derived for intervention in terms of stationary control policies. In large networks, it becomes computationally burdensome to derive an optimal control policy. To overcome this problem, greedy intervention approaches based on the concept of the Mean First Passage Time or the steady-state probability mass of the network states were previously proposed. Another possible approach is to use reduction mappings to compress the network and develop control policies on its reduced version. However, such mappings lead to loss of information and require an induction step when designing the control policy for the original network. In this paper, we propose a novel solution, CoD-CP, for designing intervention policies for large Boolean networks. The new method utilizes the Coefficient of Determination (CoD) and the Steady-State Distribution (SSD) of the model. The main advantage of CoD-CP in comparison with the previously proposed methods is that it does not require any compression of the original model, and thus can be directly designed on large networks. The simulation studies on small synthetic networks shows that CoD-CP performs comparable to previously proposed greedy policies that were induced from the compressed versions of the networks. Furthermore, on a large 17-gene gastrointestinal cancer network, CoD-CP outperforms other two available greedy techniques, which is precisely the kind of case for which CoD-CP has been developed. Finally, our experiments show that CoD-CP is robust with respect to the attractor structure of the model. The newly proposed CoD-CP provides an attractive alternative for intervening large networks where other available greedy methods require size reduction on the network and an extra induction step before designing a control policy.

  14. The politics of drug control in Nigeria: Exclusion, repression and obstacles to policy change.

    International agencies have viewed West Africa as a major player in the global trade in cocaine and heroin and in efforts to control that trade, as there have been reports of escalating arrests of drug smugglers, large-scale drug seizures and 'narco-states' in the subregion. It is claimed that a substantial share of the drugs available in Western markets transit through West Africa today and are increasingly used there as well. Notwithstanding this growing alarm, there is little serious scholarship addressing the issue of drugs and drug policy in West Africa. The article assesses and challenges some of the existing depictions of drugs and drug policy in West Africa through an empirical case study of drug control in Nigeria - one of West Africa's most notorious 'drug hubs' and recently hailed as a policy model by international experts. Based on previously inaccessible government documents, interviews with key officials in Nigeria, as well as ethnographic work at Nigeria's key drug agency, the article provides a unique insight into the politics of drug policy-making and implementation in West Africa. After describing the dominant official narratives of Nigeria's drug control, the article shows how the key political dynamics underlying drug policy remain obscured by these narratives. Nigerian drug policy has been characterised by a highly exclusive policy-making process, repression as the sole means of implementation and a strong bond with international drug agencies. This policy emerged in the 1980s and 1990s and has remained the unchallenged norm until today. The political processes underlying Nigerian drug policy also explain why policy reform has been and will be difficult to accomplish. These domestic political processes have largely been ignored in the existing depictions of drugs in West Africa, as they have mainly focused on externally driven drug threats and foreign policy responses. Most importantly, they have ignored the role played by the state. Rather

    This article explores the relationship between the prevalence of 'birth defects' and environmental characteristics, and considers implications for targeting resources to establish the educational inclusion of children affected. A household survey in four governorates across Iraq in 2010, conducted under the auspices of CARA, achieved interviews with 6032 households and collected data on more than 10,000 children and young people. Analyses suggested an association between reported presence of potential sources of contamination in local environments from human and domestic waste, and to some extent from naturally occurring contaminants and the detritus of warfare, with higher numbers of resident children having 'birth defects'. Children living in Basra were found to be most significantly impacted. This finding adds to a growing literature on associations between potential sources of environmental contaminants and impact on the health of children living in affected localities,

  18. Cost-Sensitive Bayesian Control Policy in Human Active Sensing

    2014-12-01

    Full Text Available An important but poorly understood aspect of sensory processing is the role of active sensing, the use of self-motion such as eye or head movements to focus sensing resources on the most rewarding or informative aspects of the sensory environment. Here, we present behavioral data from a visual search experiment, as well as a Bayesian model of within-trial dynamics of sensory processing and eye movements. Within this Bayes-optimal inference and control framework, which we call C-DAC (Context-Dependent Active Controller, various types of behavioral costs, such as temporal delay, response error, and sensor repositioning cost, are explicitly minimized. This contrasts with previously proposed algorithms that optimize abstract statistical objectives such as anticipated information gain (Infomax (Butko and Movellan, 2010 and one-step look-ahead accuracy (greedy MAP (Najemnik and Geisler, 2005. We find that C-DAC captures human visual search dynamics better than previous models, in particular a certain form of confirmation bias apparent in the way human subjects utilize prior knowledge about the spatial distribution of the search target to improve search speed and accuracy. We also examine several computationally efficient approximations to C-DAC that may present biologically more plausible accounts of the neural computations underlying active sensing, as well as practical tools for solving active sensing problems in engineering applications. To summarize, this paper makes several key contributions: human visual search behavioral data, a context-sensitive Bayesian active sensing model, a comparative study between different models of human active sensing, and a family of efficient approximations to the optimal model.

    Full Text Available Unlike the typical stage-based policy commonly applied in Japan, the group-based control (often called movement-based in the traffic control industry in Japan refers to such a control pattern that the controller is capable of separately allocating time to each signal group instead of stage based on traffic demand. In order to investigate its applicability at signalized intersections in Japan, an intersection located in Yokkaichi City of Mie Prefecture was selected as an experimental application site by the Japan Universal Traffic Management Society (UTMS. Based on the data collected at the intersection before and after implementing the group-based control policy respectively, this study evaluated the impacts of such a policy on driver behavior and intersection safety. To specify those impacts, a few models utilizing cycle-based data were first developed to interpret the occurrence probability and rate of red-light-running (RLR. Furthermore, analyses were performed on the yellow-entry time (Ye of the last cleared vehicle and post encroachment time (PET during the phase switching. Conclusions supported that the group-based control policy, along with certain other factors, directly or indirectly influenced the RLR behavior of through and right-turn traffics. Meanwhile, it has potential safety benefits as well, indicated by the declined Ye and increased PET values.

    Preterm birth (PTB) has been associated with exposure to air pollution, but it is unclear whether effects might vary among air pollution sources and components. We studied the relationships between PTB and exposure to different components of air pollution, including gases and particulate matter (PM) by size fraction, chemical composition, and sources. Fine and ultrafine PM (respectively, PM2.5 and PM0.1) by source and composition were modeled across California over 2000-2008. Measured PM2.5, nitrogen dioxide, and ozone concentrations were spatially interpolated using empirical Bayesian kriging. Primary traffic emissions at fine scale were modeled using CALINE4 and traffic indices. Data on maternal characteristics, pregnancies, and birth outcomes were obtained from birth certificates. Associations between PTB (n = 442,314) and air pollution exposures defined according to the maternal residence at birth were examined using a nested matched case-control approach. Analyses were adjusted for maternal age, race/ethnicity, education and neighborhood income. Adjusted odds ratios for PTB in association with interquartile range (IQR) increases in average exposure during pregnancy were 1.133 (95% CI: 1.118, 1.148) for total PM2.5, 1.096 (95% CI: 1.085, 1.108) for ozone, and 1.079 (95% CI: 1.065, 1.093) for nitrogen dioxide. For primary PM, the strongest associations per IQR by source were estimated for onroad gasoline (9-11% increase), followed by onroad diesel (6-8%) and commercial meat cooking (4-7%). For PM2.5 composition, the strongest positive associations per IQR were estimated for nitrate, ammonium, and secondary organic aerosols (11-14%), followed by elemental and organic carbon (2-4%). Associations with local traffic emissions were positive only when analyses were restricted to births with residences geocoded at the tax parcel level.

    Nuclear Safety and Security Commission(NSSC) has amended two public notices about the regulation of nuclear material accounting and control(NMAC). Those notices were declared in November 2014 and entry into force since 2015. According to this legislation, a new type of NMAC inspection system was introduced and facility rules for NMAC approved by the government should be revised subsequently. These changes were one of the preemptive actions to cope with the emergence of new international safeguards policy and increasing demand on advanced nuclear technology. Generally, the regulation policy affects the nuclear business including research and development. Therefore, understanding of the new policy and its making process may help stakeholders to minimize unnecessary financial and operational burden. This study describes background, features, and institutionalization of the new regulation policy for NMAC. The new regulation policy for NMAC was established and institutionalized to preemptively cope with the internal and external demand on 'better' national system of accounting and control of nuclear material. This new policy and regulation system may call not only the regulator but also nuclear business operators for new works to make their system more effective and efficient.

    2017-06-01

    Discrimination and inequality shape women's experiences of drug use and in the drug trade and the impact of drug control efforts on them, with disproportionate burdens faced by poor and otherwise marginalized women. In recent years, UN member states and UN drug control and human rights entities have recognized this issue and made commitments to integrate a 'gender perspective' into drug control policies, with 'gender' limited to those conventionally deemed women. But the concept of gender in international law is broader, rooted in socially constructed and culturally determined norms and expectations around gender roles, sex, and sexuality. Also, drug control policies often fail to meaningfully address the specific needs and circumstances of women (inclusively defined), leaving them at risk of recurrent violations of their rights in the context of drugs. This article explores what it means to 'mainstream' this narrower version of gender into drug control efforts, using as examples various women's experiences as people who use drugs, in the drug trade, and in the criminal justice system. It points to international guidelines on human rights and drug control as an important tool to ensure attention to women's rights in drug control policy design and implementation.

    Directory of Open Access Journals (Sweden)

    Cynthia Pizarro

    2015-01-01

    Full Text Available This paper analyzes the way in which migration policies impact in the trajectories of Bolivian women who live and work in the outskirts of the main cities of Argentina. It focuses on three cases representative of the experiences of women laborers who, coming from the poorest rural areas of Bolivia, crossed the international border when Argentine migration policy was very restrictive. It shows that symbolic and socio-economic borders keep on excluding them, as well as other labor migrants, within the Argentine territory even when the current Migration Law enacted in 2004 is more inclusive, since it grants human and social rights to the migrants. It highlights the way in which particular state control mechanisms operate nowadays both at the international border and within the Argentine territory, and analyses the difficulties that these women experience due to their positions of class, ethnic, gender, nationality and migratory status. It remarks that despite the changes in the immigration policy of Argentina, state policies keep on controlling labor migrations in accordance with the paradigm of the governance of migration. It also analyses the strategies that these women develop in order to sort out state control policies. Therefore, it considers that they are active agents even though they still have feelings of fear and trauma associated with the crossing of borders.

    2012-08-01

    Full Text Available Abstract Background While Italy has implemented some tobacco control policies over the last few decades, which resulted in a decreased smoking prevalence, there is still considerable scope to strengthen tobacco control policies consistent with the World Health Organization (WHO policy guidelines. The present study aims to evaluate the effect of past and project the effect of future tobacco control policies on smoking prevalence and associated premature mortality in Italy. Methods To assess, individually and in combination, the effect of seven types of policies, we used the SimSmoke simulation model of tobacco control policy. The model uses population, smoking rates and tobacco control policy data for Italy. Results Significant reductions of smoking prevalence and premature mortality can be achieved through tobacco price increases, high intensity media campaigns, comprehensive cessation treatment program, strong health warnings, stricter smoke-free air regulations and advertising bans, and youth access laws. With a comprehensive approach, the smoking prevalence can be decreased by as much as 12% soon after the policies are in place, increasing to a 30% reduction in the next twenty years and a 34% reduction by 30 years in 2040. Without effective tobacco control policies, a total of almost 300 thousand lives will be prematurely lost due to smoking by the year 2040. Conclusion Besides presenting the benefits of a comprehensive tobacco control strategy, the model helps identify information gaps in surveillance and evaluation schemes that will promote the effectiveness of future tobacco control policy in Italy.

    In epidemiological studies at the estimation of risk factors in the origin of specified congenital abnormalities in general birth order (parity) is considered as confounder. The aim of this study was to analyze the possible association of first and high (four or more) birth order with the risk of congenital abnormalities in a population-based case-matched control data set. The large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities included 21,494 cases with different isolated congenital abnormality and their 34,311 matched controls. First the distribution of birth order was compared of 24 congenital abnormality groups and their matched controls. In the second step the possible association of first and high birth order with the risk of congenital abnormalities was estimated. Finally some subgroups of neural-tube defects, congenital heart defects and abdominal wall's defects were evaluated separately. A higher risk of spina bifida aperta/cystica, esophageal atresia/stenosis and clubfoot was observed in the offspring of primiparous mothers. Of 24 congenital abnormality groups, 14 had mothers with larger proportion of high birth order. Ear defects, congenital heart defects, cleft lip± palate and obstructive defects of urinary tract had a linear trend from a lower proportion of first born cases to the larger proportion of high birth order. Birth order showed U-shaped distribution of neural-tube defects and clubfoot, i.e. both first and high birth order had a larger proportion in cases than in their matched controls. Birth order is a contributing factor in the origin of some isolated congenital abnormalities. The higher risk of certain congenital abnormalities in pregnant women with first or high birth order is worth considering in the clinical practice, e.g. ultrasound scanning.

    Low birth weight (LBW) is associated with increased risk of developing type 2 diabetes later in life. Progression from normal to impaired glucose tolerance and overt diabetes may depend, to some extent, on elevation of plasma free fatty acids (FFAs). We undertook this study to elucidate whether...... a prolonged physiological lipid load could unmask or augment existing metabolic defects in otherwise healthy young LBW subjects. Forty 19-year-old men (LBW [n = 20], controls [normal birth weight, NBW] [n = 20]) without a family history of diabetes underwent an intravenous glucose tolerance test (0.3 g kg(-1......)), followed by 2-step hyperinsulinemic-euglycemic clamps (2 x 120 minutes: 10 and 40 mU m(-2) min(-1)) in combination with [3-3H]-glucose and indirect calorimetry. The tests were preceded, in randomized order, by a 24-hour continuous intralipid (20%, 0.4 mg mL(-1) h(-1)) or saline infusion. Estimates...

    How do fertility control policies contribute to the welfare of women, and their husbands, particularly as they get older? We consider whether the reduction in fertility resulting from population control policies has had any effect on the health of elderly parents in China. In particular, we examine the influence of this fertility decline, experienced due to China's one-child policy, on several measures of the health of parents in middle and old age. Overall, our results suggest that having fewer children has a positive effect on self-reported parental health but generally no effect on other measures of health. The results also suggest that upstream financial transfers have a positive effect on several measures of parental health. Copyright © 2014 John Wiley & Sons, Ltd.

    Participants in the Seminar on Population Policies for Top-level Policy Makers and Program Managers, meeting in Thailand during January 1987, examined the challenges now facing them regarding the implementation of fertility regulation programs in their respective countries -- Bangladesh, China, India, Indonesia, Malaysia, Nepal, Pakistan, the Philippines, the Republic of Korea, and Thailand. This Seminar was organized to coincide with the completion of an Economic and Social Commission for Asia and the Pacific (ESCAP) study investigating the impact and efficiency of family planning programs in the region. Country studies were reviewed at the Seminar along with policy issues about the status of women, incentive and disincentive programs, and socioeconomic factors affecting fertility. In Bangladesh the government recognizes population growth as its top priority problem related to the socioeconomic development of the country and is working to promote a reorientation strategy from the previous clinic-oriented to a multidimensional family welfare program. China's family planning program seeks to postpone marraige, space the births of children between 3-5 years, and promote the 1-child family. Its goal is to reduce the rate of natural increase from 12/1000 in 1978 to 5/1000 by 1985 and 0 by 2000. India's 7th Five-Year-Plan (1986-90) calls for establishing a 2-child family norm by 2000. In Indonesia the government's population policy includes reducing the rate of population growth, achieving a redistribution of the population, adjusting economic factors, and creating prosperous families. The government of Indonesia reversed its policy to reduce the population growth rate in 1984 and announced its goal of achieving a population of 70 million by 2100 in order to support mass consumption industries. It has created an income tax deduction system favoring large families and maternity benefits for women who have up to 5 children as incentives. Nepal's official policy is to

    The aim was to investigate birth characteristics, obstetric and neonatal outcomes of the first childbirth in women with Marfan syndrome by use of Swedish national registers since pregnancy-related outcomes in women with Marfan syndrome have only been sparsely investigated. In this national population-based cohort study and matched case-control study of Swedish women born 1973-1993, women with Marfan syndrome (n=273) were compared to women without the condition (n=1 017 265). The study population was followed until 2013. A total of 364 553 mother-firstborn-offspring pairs were analyzed. Sixty-one women with Marfan syndrome became mothers. Women with Marfan syndrome were also compared to 543 healthy controls. Women with Marfan syndrome were more often born preterm (pMarfan syndrome had no increased risk of giving birth by cesarean section (p=0.079). No increased neonatal risks in their children were found. Women with Marfan syndrome were less likely to give birth than those without (pMarfan syndrome were more likely to be born preterm, SGA and by cesarean section. These increased risks of preterm birth and SGA babies were not found in connection with their own first childbirth. Pregnancies with known fetal Marfan syndrome have to be carefully monitored. The results are important for obstetricians giving preconception counseling and treating women with Marfan syndrome. Further studies are needed to evaluate risks during pregnancy and long-term effects of pregnancy on the cardiovascular status of women with Marfan syndrome. Copyright © 2017 Elsevier B.V.

    Resolution of inflammation is an active process involving specialised pro-resolving mediators (SPM) generated from the n-3 fatty acids EPA and DHA. n-3 Fatty acid supplementation during pregnancy may provide an intervention strategy to modify these novel SPM. This study aimed to assess the effect of n-3 fatty acid supplementation in pregnancy on offspring SPM at birth and 12 years of age (12 years). In all, ninety-eight atopic pregnant women were randomised to 3·7 g daily n-3 fatty acids or a control (olive oil), from 20 weeks gestation until delivery. Blood was collected from the offspring at birth and at 12 years. Plasma SPM consisting of 18-hydroxyeicosapentaenoic acid (18-HEPE), E-series resolvins, 17-hydroxydocosahexaenoic acid (17-HDHA), D-series resolvins, 14-hydroxydocosahexaenoic acid (14-HDHA), 10 S,17S-dihydroxydocosahexaenoic acid, maresins and protectin 1, were measured by liquid chromatography-tandem MS. We identified the resolvins RvE1, RvE2, RvE3, RvD1, 17R-RvD1 and RvD2 for the first time in human cord blood. n-3 Fatty acids increased cord blood 18-HEPE (Pbirth was significantly increased in the n-3 fatty acid group relative to the controls (P=0·001), but other SPM were not different between the groups. n-3 Fatty acid supplementation during pregnancy was associated with an increase in SPM precursors in the offspring at birth but the effects were not sustained at 12 years. The presence of these SPM, particularly at birth, may have functions relevant in the newborn that remain to be established, which may be useful for future investigations.

    Higher tobacco retailer density promotes smoking by making cigarettes more accessible and available, and by increasing environmental cues to smoke. We aimed to examine tobacco control experts' views on policies that could reduce tobacco retail availability. Telephone interviews with 25 individuals drawn from academia, non-governmental organisations, Māori and Pacific health, smoking cessation services, district health boards and other public health-related organisations. We used a semi-structured interview guide to explore the perceived importance of reducing tobacco retail supply, views on different policy options and barriers to policy adoption. Qualitative content analysis was conducted using transcripts as the data source. Participants believed tobacco retailer licensing was an important short-term step towards the 2025 goal. In the long-term, participants envisaged tobacco only being available at a small number of specialised outlets, either pharmacies or adult-only stores. To achieve that long-term scenario, participants suggested a sinking-lid policy on licences or a zoning approach could be adopted to gradually reduce outlet density. Policies banning sales at certain types of outlet were not considered feasible. There is tension between the tobacco retail reduction policies seen as more likely to be politically acceptable, and the need to make substantial changes to the tobacco retail environment by 2025. Future research could investigate possible legal mechanisms for requiring existing tobacco retailers to transition out of selling tobacco.

    Objective: To evaluate the efficacy of orally administered probiotics in preventing necrotizing enterocolitis (NEC) in preterm very low birth weight (VLBW) infants. Study Design: Arandomized double blind controlled trial. Place and Duration of Study: The Paediatrics Department of Sylhet M.A.G. Osmani Medical College Hospital, Sylhet Bangladesh, from July 2012 to June 2015. Methodology: Preterm (28 - 33 weeks gestation) VLBW (birth weight 1000 - 1499 g) neonates were enrolled. The study group was fed with probiotics once daily with breast milk from first feeding, and the control group with only breast milk without the addition of probiotics. Both the groups received other standard care. The primary outcome was the development of NEC (stage II and III), categorized by modified Bell's classification. Result: In 108 neonates, development of NEC was significantly lower in the study group than that of control group [1 (1.9 percent) vs. 6 (11.5 percent); p=0.044]. Age of achievement of full oral feeding was significantly earlier in the study group than that in the control group (14.88 ±3.15 and 18.80 ±4.32 days; p < 0.001). Duration of hospital stay was significantly short in the study group compared to the control group (15.82 ±2.94 days vs. 19.57 ±4.26 days; p < 0.001). Conclusion: Probiotic supplementation reduces the frequency of necrotising enterocolitis in preterm neonates with very low birth weight. It is also associated with faster achievement of full oral feeding and short duration of hospital stay. (author)

    Low birth weight (LBW) is a risk factor for infant mortality, morbidity, growth retardation, poor cognitive development, and chronic diseases. Maternal exposure to diseases such as malaria, HIV, and syphilis has been shown to have a significant impact on birth weight (BW). This study was aimed...... at determining whether there was a difference in rates of LBW in areas of varying malaria transmission intensity in Korogwe, Tanzania. Retrospective data for one year (June 2004-May 2005) in three maternal and child health (MCH) clinics in the district were analysed. Villages were stratified into three strata...... babies compared to first parity women (OR=0.44, 95% CI 0.19-0.98, P=0.045). Similarly, the risk of LBW was higher in women who had delayed MCH gestational booking and in women who conceived during high malaria transmission seasons. There was high degree of preference of digits ending with 0...

    Driverless cars with artificial intelligence (AI) and automated supermarkets run by collaborative robots (cobots) working without human supervision have sparked off new debates: what will be the impacts of extreme automation, turbocharged by the Internet of Things (IoT), AI, and the Industry 4.0, on Big Data and omics implementation science? The IoT builds on (1) broadband wireless internet connectivity, (2) miniaturized sensors embedded in animate and inanimate objects ranging from the house cat to the milk carton in your smart fridge, and (3) AI and cobots making sense of Big Data collected by sensors. Industry 4.0 is a high-tech strategy for manufacturing automation that employs the IoT, thus creating the Smart Factory. Extreme automation until "everything is connected to everything else" poses, however, vulnerabilities that have been little considered to date. First, highly integrated systems are vulnerable to systemic risks such as total network collapse in the event of failure of one of its parts, for example, by hacking or Internet viruses that can fully invade integrated systems. Second, extreme connectivity creates new social and political power structures. If left unchecked, they might lead to authoritarian governance by one person in total control of network power, directly or through her/his connected surrogates. We propose Industry 5.0 that can democratize knowledge coproduction from Big Data, building on the new concept of symmetrical innovation. Industry 5.0 utilizes IoT, but differs from predecessor automation systems by having three-dimensional (3D) symmetry in innovation ecosystem design: (1) a built-in safe exit strategy in case of demise of hyperconnected entrenched digital knowledge networks. Importantly, such safe exists are orthogonal-in that they allow "digital detox" by employing pathways unrelated/unaffected by automated networks, for example, electronic patient records versus material/article trails on vital medical information; (2) equal

    Explaining policy change is one of the central tasks of contemporary policy analysis. In this article, we examine the changes in infection control policies for multi-drug resistant tuberculosis (MDR-TB) in South Africa from the time the country made the transition to democracy in 1994, until 2015. We focus on MDR-TB infection control and refer to decentralised management as a form of infection control. Using Kingdon's theoretical framework of policy streams, we explore the temporal ordering of policy framework changes. We also consider the role of research in motivating policy changes. Policy documents addressing MDR-TB in South Africa over the period 1994 to 2014 were extracted. Literature on MDR-TB infection control in South Africa was extracted from PubMed using key search terms. The documents were analysed to identify the changes that occurred and the factors driving them. During the period under study, five different policy frameworks were implemented. The policies were meant to address the overwhelming challenge of MDR-TB in South Africa, contextualised by high prevalence of HIV infection, that threatened to undermine public health programmes and the success of antiretroviral therapy rollouts. Policy changes in MDR-TB infection control were supported by research evidence and driven by the high incidence and complexity of the disease, increasing levels of dissatisfaction among patients, challenges of physical, human and financial resources in public hospitals, and the ideologies of the political leadership. Activists and people living with HIV played an important role in highlighting the importance of MDR-TB as well as exerting pressure on policymakers, while the mass media drew public attention to infection control as both a cause of and a solution to MDR-TB. The critical factors for policy change for infection control of MDR-TB in South Africa were rooted in the socioeconomic and political environment, were supported by extensive research, and can be framed

    High maternal mortality has remained an unmet public health challenge in the developing world. Maternal mortality in Ethiopia is among the highest in the world. Since most maternal deaths occur during labor, delivery, and the immediate postpartum period, facility delivery with skilled birth attendants is recommended to reduce maternal mortality. Nonetheless, the majority of women in Ethiopia give birth at home. Individual attributes and availability and accessibility of services deter service utilization. The role of social networks that may facilitate or constrain service use is not well studied. Community-based case-control study was conducted between February and March 2014 in Jabi Tehinan District, North West Ethiopia. Retrospective data were collected from 134 women who had uncomplicated births at health facilities and 140 women who had uncomplicated births at home within a year preceding the survey. Interviews were held with eight women who had uncomplicated births at health facilities and 11 who had uncomplicated births at home. The quantitative data were entered and analyzed using SPSS for Windows versions 16.0 and hierarchical logistic regression model was used for analysis. The qualitative data were transcribed verbatim and data were used to substantiate the quantitative data. The results indicated that social network variables were significantly associated with the use of health facilities for delivery. Taking social networks into account improved the explanation of facility use for delivery services over women's individual attributes. Women embedded within homogeneous network members (Adjusted OR 2.53; 95% CI: 1.26-5.06) and embedded within high SBA endorsement networks (Adjusted OR 7.97; 95% CI: 4.07-12.16) were more likely to deliver at health facilities than their counterparts. Women living in urban areas (Adjusted OR 3.32; 95% CI: 1.37-8.05) and had better knowledge of obstetric complications (Adjusted OR 3.01; 95% CI: 1.46-6.18) were more likely to

    Full Text Available Methicillin-resistant Staphylococcus aureus (MRSA is a major cause of preventable nosocomial infections and is endemic in hospitals worldwide. The effectiveness of infection control policies varies significantly across hospital settings. The impact of the hospital context towards the rate of nosocomial MRSA infections and the success of infection control is understudied. We conducted a modelling study to evaluate several infection control policies in surgical, intensive care, and medical ward specialties, each with distinct ward conditions and policies, of a tertiary public hospital in Sydney, Australia. We reconfirm hand hygiene as the most successful policy and find it to be necessary for the success of other policies. Active screening for MRSA, patient isolation in single-bed rooms, and additional staffing were found to be less effective. Across these ward specialties, MRSA transmission risk varied by 13% and reductions in the prevalence and nosocomial incidence rate of MRSA due to infection control policies varied by up to 45%. Different levels of infection control were required to reduce and control nosocomial MRSA infections for each ward specialty. Infection control policies and policy targets should be specific for the ward and context of the hospital. The model we developed is generic and can be calibrated to represent different ward settings and pathogens transmitted between patients indirectly through health care workers. This can aid the timely and cost effective design of synergistic and context specific infection control policies.

    Policy decisions for malaria control are often difficult to make as decision-makers have to carefully consider an array of options and respond to the needs of a large number of stakeholders. This study assessed the factors and specific objectives that influence malaria control policy decisions, as a crucial first step towards developing an inclusive malaria decision analysis support tool (MDAST). Country-specific stakeholder engagement activities using structured questionnaires were carried out in Kenya, Uganda and Tanzania. The survey respondents were drawn from a non-random purposeful sample of stakeholders, targeting individuals in ministries and non-governmental organizations whose policy decisions and actions are likely to have an impact on the status of malaria. Summary statistics across the three countries are presented in aggregate. Important findings aggregated across countries included a belief that donor preferences and agendas were exerting too much influence on malaria policies in the countries. Respondents on average also thought that some relevant objectives such as engaging members of parliament by the agency responsible for malaria control in a particular country were not being given enough consideration in malaria decision-making. Factors found to influence decisions regarding specific malaria control strategies included donor agendas, costs, effectiveness of interventions, health and environmental impacts, compliance and/acceptance, financial sustainability, and vector resistance to insecticides. Malaria control decision-makers in Kenya, Uganda and Tanzania take into account health and environmental impacts as well as cost implications of different intervention strategies. Further engagement of government legislators and other policy makers is needed in order to increase funding from domestic sources, reduce donor dependence, sustain interventions and consolidate current gains in malaria.

    The DHA to Optimize Mother Infant Outcome (DOMInO) and Kansas DHA Outcomes Study (KUDOS) were randomized controlled trials that supplemented mothers with 800 and 600mg DHA/day, respectively, or a placebo during pregnancy. DOMInO was conducted in Australia and KUDOS in the United States. Both trials found an unanticipated and statistically significant reduction in early preterm birth (ePTB; i.e., birth before 34 weeks gestation). However, in each trial, the number of ePTBs were small. We used a novel Bayesian approach to estimate statistically derived low, moderate or high risk for ePTB, and to test for differences between the DHA and placebo groups. In both trials, the model predicted DHA would significantly reduce the expected proportion of deliveries in the high risk group under the trial conditions of the parent studies. Among the next 300,000 births in Australia we estimated that 1112 ePTB (95% credible interval 51-2189) could be avoided by providing DHA. And in the USA we estimated that 106,030 ePTB (95% credible interval 6400 to 175,700) could be avoided with DHA. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Since the 1970s, Israel's educational policy has been undergoing a change generated by the neo-liberal agenda. In this light, it is not surprising that since the 1990s, Israel's education system has adopted the main characteristics of the Global Education Reform Movement (GERM). In light of this, the current research will focus on a newly born…

  20. Domestic politics, citizen activism, and U.S. nuclear arms control policy

    International Nuclear Information System (INIS)

    Knopf, J.W.

    1991-01-01

    The author seeks to ascertain whether and how citizens' movements concerning nuclear arms control and disarmament affect US arms control policy. The author employs a comparative case study methodology. He examines cases of the Eisenhower and Kennedy Administrations during the period of protest against nuclear testing, and the Reagan Administration during the nuclear weapons freeze campaign and the subsequent campaign for a comprehensive test ban. He hows there are four mechanisms through which public advocacy efforts can influence arms control policy, identifies the conditions under which each can be effective, and details the type of impact each mechanism has. Domestic activism interacts with broader public opinion in a way that creates electoral pressure; with elite-level debates in a way that removes a consensus behind presidential policy or changes the winning coalition in Congress; with bureaucratic politics, by generating ideas that have utility for some agents within the Executive; or with the public diplomacy of foreign governments, especially the Soviet Union. Citizens' movements had an impact on policy in each of the cases studied. The type and extent of impact, and the mechanisms involved in giving activism influence, are different for each case

    Full Text Available To achieve the goals of national sustainable development, the peaking control of CO2 emissions is pivotal, as well as other pollutants. In this paper, we build a Chinese inter-regional CGE model and simulate 13 policies and their combinations. By analyzing the energy consumptions, coal consumptions, relating emissions and their impacts on GDP, we found that with the structure adjustment policy, the proportion of coal in primary fossil fuels in 2030 will decrease from 53% to 48% and CO2 emissions will decrease by 11.3%–22.8% compared to the baseline scenario. With the energy intensity reduction policy, CO2 emissions will decrease by 33.3% in 2030 and 47.8% in 2050 than baseline scenario. Other pollutants will also be controlled as synergetic effects. In this study we also find that although the earlier the peaking time the better for emission amounts control, the economic costs can not be ignored. The GDP will decrease by 2.96%–8.23% under different scenarios. Therefore, integrated policy solutions are needed for realizing the peaks package and more targeted measures are required to achieve the peaks of other pollutants earlier.

    Despite the success of rotavirus vaccines, suboptimal vaccine efficacy in regions with a high burden of disease continues to present a challenge to worldwide implementation. A birth dose strategy with a vaccine developed from an asymptomatic neonatal rotavirus strain has the potential to address this challenge and provide protection from severe rotavirus disease from birth. This phase 2a randomised, double-blind, three-arm, placebo-controlled safety and immunogenicity trial was undertaken at a single centre in New Zealand between Jan 13, 2012, and April 17, 2014. Healthy, full-term (≥36 weeks gestation) babies, who weighed at least 2500 g, and were 0-5 days old at the time of randomisation were randomly assigned (1:1:1; computer-generated; telephone central allocation) according to a concealed block randomisation schedule to oral RV3-BB vaccine with the first dose given at 0-5 days after birth (neonatal schedule), to vaccine with the first dose given at about 8 weeks after birth (infant schedule), or to placebo. The primary endpoint was cumulative vaccine take (serum immune response or stool shedding of vaccine virus after any dose) after three doses. The immunogenicity analysis included all randomised participants with available outcome data. This trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12611001212943. 95 eligible participants were randomised, of whom 89 were included in the primary analysis. A cumulative vaccine take was detected in 27 (90%) of 30 participants in the neonatal schedule group after three doses of RV3-BB vaccine compared with four (13%) of 32 participants in the placebo group (difference in proportions 0·78, 95% CI 0·55-0·88; protavirus vaccines.

    2014-05-01

    Full Text Available Tobacco use is the most important preventable risk factor for premature death. The World Health Organization (WHO Framework Convention on Tobacco Control (FCTC, the first international public health treaty, came into force in 2005. This paper reviews the present status of tobacco control policies in Korea according to the WHO FCTC recommendations. In Korea, cigarette use is high among adult males (48.2% in 2010, and cigarette prices are the lowest among the Organization for Economic Cooperation and Development countries with no tax increases since 2004. Smoke-free policies have shown incremental progress since 1995, but smoking is still permitted in many indoor public places. More than 30% of non-smoking adults and adolescents are exposed to second-hand smoke. Public education on the harmful effects of tobacco is currently insufficient and the current policies have not been adequately evaluated. There is no comprehensive ban on tobacco advertising, promotion, or sponsorship in Korea. Cigarette packages have text health warnings on only 30% of the main packaging area, and misleading terms such as "mild" and "light" are permitted. There are nationwide smoking cessation clinics and a Quitline service, but cessation services are not covered by public insurance schemes and there are no national treatment guidelines. The sale of tobacco to minors is prohibited by law, but is poorly enforced. The socioeconomic inequality of smoking prevalence has widened, although the government considers inequality reduction to be a national goal. The tobacco control policies in Korea have faltered recently and priority should be given to the development of comprehensive tobacco control policies.

  5. Tobacco-control policies in tobacco-growing states: where tobacco was king.

    Science.gov (United States)

    Fallin, Amanda; Glantz, Stanton A

    2015-06-01

    POLICY POINTS: The tobacco companies prioritized blocking tobacco-control policies in tobacco-growing states and partnered with tobacco farmers to oppose tobacco-control policies. The 1998 Master Settlement Agreement, which settled state litigation against the cigarette companies, the 2004 tobacco-quota buyout, and the companies' increasing use of foreign tobacco led to a rift between the companies and tobacco farmers. In 2003, the first comprehensive smoke-free local law was passed in a major tobacco-growing state, and there has been steady progress in the region since then. Health advocates should educate the public and policymakers on the changing reality in tobacco-growing states, notably the major reduction in the volume of tobacco produced. The 5 major tobacco-growing states (Kentucky, North Carolina, South Carolina, Tennessee, and Virginia) are disproportionately affected by the tobacco epidemic, with higher rates of smoking and smoking-induced disease. These states also have fewer smoke-free laws and lower tobacco taxes, 2 evidence-based policies that reduce tobacco use. Historically, the tobacco farmers and hospitality associations allied with the tobacco companies to oppose these policies. This research is based on 5 detailed case studies of these states, which included key informant interviews, previously secret tobacco industry documents (available at http://legacy.library.ucsf.edu), and media articles. This was supplemented with additional tobacco document and media searches specifically for this article. The tobacco companies were particularly concerned about blocking tobacco-control policies in the tobacco-growing states by promoting a pro-tobacco culture, beginning in the late 1960s. Nevertheless, since 2003, there has been rapid progress in the tobacco-growing states' passage of smoke-free laws. This progress came after the alliance between the tobacco companies and the tobacco farmers fractured and hospitality organizations stopped opposing smoke

    Since 2005, Brazil has been a Party of the World Health Organization Framework Convention on Tobacco Control, an international treaty whose measures are the foundation of the National Tobacco-Control Policy (NTCP), of Brazil. The results evidence a significant decrease in the prevalence of smokers and in tobacco-related morbidity and mortality. These results, however, could have been even better if there wasn't the interference of the tobacco supply chain (TSC), controlled by transnational corporations, which has become more intense over the last 10 years. These companies made Brazil not only a repository for tobacco, but also for economic and political power capable of threatening NTCP achievements. This Essay recounts the development of NTCP and the tobacco supply chain modus operandi to hamper it, and discusses how the strengthening of policies to promote alternative crops for tobacco could shield NTCP from such interference.

  7. The need for a formalised system of Quality Control for environmental policy-science.

    Larcombe, Piers; Ridd, Peter

    2018-01-01

    Research science used to inform public policy decisions, herein defined as "Policy-Science", is rarely subjected to rigorous checking, testing and replication. Studies of biomedical and other sciences indicate that a considerable fraction of published peer-reviewed scientific literature, perhaps half, has significant flaws. To demonstrate the potential failings of the present approaches to scientific Quality Control (QC), we describe examples of science associated with perceived threats to the Great Barrier Reef (GBR), Australia. There appears a serious risk of efforts to improve the health of the GBR being directed inefficiently and/or away from the more serious threats. We suggest the need for a new organisation to undertake quality reviews and audits of important scientific results that underpin government spending decisions on the environment. Logically, such a body could also examine policy science in other key areas where governments rely heavily upon scientific results, such as education, health and criminology.

This research was aimed to analyze the excess inventories issue in pharmacy and medical equipment unit at a local hospital in Bandung which affected the service level of the hospital. As one of the busy hospital in Java, proven by the higher amount of the patient/year than in other average Java typical hospital, the hospital needs to concern about the pharmaceutical and medical equipment inventories in order to fulfill patients’ needs and in the same time keeping the inventory level under control. Therefore, an inventory control evaluation was conducted to determine the appropriate number of inventories and time of order to avoid the excessive goods in central warehouse of the hospital. By using probabilistic inventory model and continuous review policy, the pharmaceutical inventory in the hospital was calculated to compare the ideal and actual amount of the average inventory level (AIL.

    Objectives. We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). Methods. We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. Results. Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. Conclusions. Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking. PMID:23327252

    The U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Site Office (NNSA/NSO) has implemented varying institutional control policies in performance assessment/composite analysis (PA/CA) calculations for the Area 5 and Area 3 Radioactive Waste Management Sites (RWMSs) (Shott et al., 1998; 2000; Bechtel Nevada [BN] and Neptune and Company Inc. [Neptune], 2006). The facilities are within the actively maintained boundaries of the Nevada Test Site (NTS) that are enforced by NNSA/NSO. Under current policies, access required for exposure of the member of public (MOP) or the inadvertent human intruder (IHI) is prohibited. Uncertainties affecting institutional control policies are the duration and effectiveness of the controls during the post-closure period. Implementing a uniform set of institutional control policies for the RWMSs that encompasses waste management and environmental restoration programs and is consistent with the end-state vision for the environmental management programs for the NTS (DOE, 2006) is a primary goal of the maintenance program. The NNSA/NSO Performance Management Plan (DOE, 2002) complies with DOE Policy P455.1, 'Use of Risk-Based End States' (DOE, 2003a). Expected future land uses are a driver in selecting acceptable end state conditions and clean-up goals for the NTS. NNSA/NSO Environmental Management's (EM's) land management assumptions and framework for Environmental Management activities are as follows: The NTS will remain under federal control in perpetuity as an NNSA test site, and the large buffer zone surrounding the NTS (the Nevada Test and Training Range) is assumed to remain under the control of the U.S. Air Force. There are no plans for transfer of any NTS lands to other agencies or public entities. Access will continue to be restricted to the NTS and the surrounding areas. For management purposes, NNSA/NV EM activities have been established based on the source of contamination and

    To evaluate the birth outcomes and maternal variables of cases with different types of left-sided obstructive defects (LSOD) of the heart. Live-born infants were selected from the population-based large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities, and 302 cases with LSOD, 469 matched controls and 38,151 all controls without any defect, and 20,750 malformed controls with other isolated defects were compared. The diagnosis of LSOD was based on autopsy report or the documents of surgical intervention. Four types of LSOD were differentiated: 56 cases with valvular aortic stenosis (VAS), 76 cases with hypoplastic left heart syndrome (HLHS), 113 cases with coarctation of the aorta (COA) and 57 cases with other congenital abnormalities of aorta (OCA). Cases with LSOD had male excess (64.6%) with a higher rate of preterm birth (14.2 vs. 6.6%) and low birthweight (15.6 vs. 4.3%) compared to matched controls. The high rate of preterm birth was particularly characteristic for HLHS (17.1%) while intrauterine fetal growth restriction was found in cases OCA (22.8%) and COA (13.3%). The mothers of cases with LSOD had higher birth order and lower socio-economic status than controls without any defect. The general pattern of birth outcomes and maternal variables were similar in the types of LSOD cases, but the higher rate of preterm birth and low birthweight indicated some association with their adverse fetal development.

  13. A Single, Continuously Applied Control Policy for Modeling Reaching Movements with and without Perturbation.

    2018-02-01

    It has been debated whether kinematic features, such as the number of peaks or decomposed submovements in a velocity profile, indicate the number of discrete motor impulses or result from a continuous control process. The debate is particularly relevant for tasks involving target perturbation, which can alter movement kinematics. To simulate such tasks, finite-horizon models require two preset movement durations to compute two control policies before and after the perturbation. Another model employs infinite- and finite-horizon formulations to determine, respectively, movement durations and control policies, which are updated every time step. We adopted an infinite-horizon optimal feedback control model that, unlike previous approaches, does not preset movement durations or use multiple control policies. It contains both control-dependent and independent noises in system dynamics, state-dependent and independent noises in sensory feedbacks, and different delays and noise levels for visual and proprioceptive feedbacks. We analytically derived an optimal solution that can be applied continuously to move an effector toward a target regardless of whether, when, or where the target jumps. This single policy produces different numbers of peaks and "submovements" in velocity profiles for different conditions and trials. Movements that are slower or perturbed later appear to have more submovements. The model is also consistent with the observation that subjects can perform the perturbation task even without detecting the target jump or seeing their hands during reaching. Finally, because the model incorporates Weber's law via a state representation relative to the target, it explains why initial and terminal visual feedback are, respectively, less and more effective in improving end-point accuracy. Our work suggests that the number of peaks or submovements in a velocity profile does not necessarily reflect the number of motor impulses and that the difference between

    Preterm birth accounts for more than 85% of all perinatal complications and deaths. Seventy-five per cent of early preterm births (EPTBs) occur spontaneously and without identifiable risk factors. The need for a broadly applicable, effective strategy for primary prevention is paramount. Secondary outcomes from the docosahexaenoic acid (DHA) to Optimise Mother Infant Outcome trial showed that maternal supplementation until delivery with omega-3 (ω-3) long chain polyunsaturated fatty acid (LCPUFA), predominantly as DHA, resulted in a 50% reduction in the incidence of EPTB and an increase in the incidence of post-term induction or post-term prelabour caesarean section due to extended gestation. We aim to determine the effectiveness of supplementing the maternal diet with ω-3 LCPUFA until 34 weeks' gestation on the incidence of EPTB. This is a multicentre, parallel group, randomised, blinded and controlled trial. Women less than 20 weeks' gestation with a singleton or multiple pregnancy and able to give informed consent are eligible to participate. Women will be randomised to receive high DHA fish oil capsules or control capsules without DHA. Capsules will be taken from enrolment until 34 weeks' gestation. The primary outcome is the incidence of EPTB, defined as delivery before 34 completed weeks' gestation. Key secondary outcomes include length of gestation, incidence of post-term induction or prelabour caesarean section and spontaneous EPTB. The target sample size is 5540 women (2770 per group), which will provide 85% power to detect an absolute reduction in the incidence of preterm birth of 1.16% (from 2.45% to 1.29%) between the DHA and control group (two sided α=0.05). The primary analysis will be based on the intention-to-treat principle.

    Full Text Available We investigate the dynamic behaviors of a two-prey one-predator system with stage structure and birth pulse for predator. By using the Floquet theory of linear periodic impulsive equation and small amplitude perturbation method, we show that there exists a globally asymptotically stable two-prey eradication periodic solution when the impulsive period is less than some critical value. Further, we study the permanence of the investigated model. Our results provide valuable strategy for biological economics management. Numerical analysis is also inserted to illustrate the results.

  20. The Impact of Family Control on Dividend Policy: Evidence from Indonesia

    2016-12-01

    Full Text Available This paper examines the relationship between family control and dividend policy in Indonesia. There are three possible explanations for the relationship. The expropriation hypothesis predicts that family control has a negative impact on dividend payouts. Meanwhile the reputation hypothesis and the family income hypothesis predict that family control has a positive impact on dividend payouts. Using a panel data of Indonesian publicly listed firms in the period of 2003-2009, the results shows that family control has a significant negative impact on dividend payouts, dividend yields and likelyhood to pay dividends. The results control for other variables that may potentially affect dividend payments such as growth opportunity, debt, profitability, firm size and firm age. From agency theory perspective, the finding is consistent with the argument that family controlling shareholders prefer lower dividends, in order to preserve cash flows that they can potentially expropriate (the expropriation hypothesis.

    Fetal fibronectin is an extracellular matrix glycoprotein that is produced by amniocytes and cytotrophoblasts and has been shown to predict spontaneous preterm birth. The aim of this systematic review and metaanalysis of randomized clinical trials was to evaluate the effect of the use of fetal fibronectin in the prevention of preterm birth in singleton pregnancies with threatened preterm labor. The research was conducted with the use of MEDLINE, EMBASE, Web of Sciences, Scopus, ClinicalTrial.gov, OVID, and Cochrane Library as electronic databases from the inception of each database to February 2016. Selection criteria included randomized clinical trials of singleton gestations with threatened preterm labor that were assigned randomly to management based on fetal fibronectin results (ie, intervention group) or not (ie, comparison group). Types of participants included women with singleton gestations at 23 0/7 to 34 6/7 weeks with threatened preterm labor. Studies that included management that was also based on the use of sonographic cervical length were excluded. The primary outcome was preterm birth at birth at control group. No differences were found in the number of women who delivered within 7 days (12.8% vs 14.5%; relative risk, 0.76; 95% confidence interval, 0.47-1.21), in the mean of gestational age at delivery (mean difference, 0.20 week; 95% confidence interval, -0.26 to 0.67), in the rate of maternal hospitalization (27.4% vs 26.9%; relative risk, 1.07; 95% confidence interval, 0.80-1.44), in the use of tocolysis (25.3% vs 28.2%; relative risk, 0.97; 95% confidence interval, 0.75-1.24), antenatal steroids (29.2% vs 29.2%; relative risk, 1.05; 95% confidence interval, 0.79-1.39), in the mean time in the triage unit (mean difference, 0.60 hour; 95% confidence interval, -0.03 to 1.23) and in neonatal outcomes that included respiratory distress syndrome (1.3% vs 1.5%; relative risk, 0.91; 95% confidence interval, 0.06-14.06), and admission to the neonatal

    Industrial flow lines are composed of unit processes operating on a fast time scale and performance measurements known as operational indices measured at a slower time scale. This paper presents a model-free optimal solution to a class of two time-scale industrial processes using off-policy reinforcement learning (RL). First, the lower-layer unit process control loop with a fast sampling period and the upper-layer operational index dynamics at a slow time scale are modeled. Second, a general optimal operational control problem is formulated to optimally prescribe the set-points for the unit industrial process. Then, a zero-sum game off-policy RL algorithm is developed to find the optimal set-points by using data measured in real-time. Finally, a simulation experiment is employed for an industrial flotation process to show the effectiveness of the proposed method.

  3. Radon, Smoking, and Lung Cancer: The Need to Refocus Radon Control Policy

    2013-01-01

    Exposure to radon is the second leading cause of lung cancer, and the risk is significantly higher for smokers than for nonsmokers. More than 85% of radon-induced lung cancer deaths are among smokers. The most powerful approach for reducing the public health burden of radon is shaped by 2 overarching principles: public communication efforts that promote residential radon testing and remediation will be the most cost effective if they are primarily directed at current and former smokers; and focusing on smoking prevention and cessation is the optimal strategy for reducing radon-induced lung cancer in terms of both public health gains and economic efficiency. Tobacco control policy is the most promising route to the public health goals of radon control policy. PMID:23327258

  4. The Brazil SimSmoke policy simulation model: the effect of strong tobacco control policies on smoking prevalence and smoking-attributable deaths in a middle income nation.

    Full Text Available Brazil has reduced its smoking rate by about 50% in the last 20 y. During that time period, strong tobacco control policies were implemented. This paper estimates the effect of these stricter policies on smoking prevalence and associated premature mortality, and the effect that additional policies may have.The model was developed using the SimSmoke tobacco control policy model. Using policy, population, and smoking data for Brazil, the model assesses the effect on premature deaths of cigarette taxes, smoke-free air laws, mass media campaigns, marketing restrictions, packaging requirements, cessation treatment programs, and youth access restrictions. We estimate the effect of past policies relative to a counterfactual of policies kept to 1989 levels, and the effect of stricter future policies. Male and female smoking prevalence in Brazil have fallen by about half since 1989, which represents a 46% (lower and upper bounds: 28%-66% relative reduction compared to the 2010 prevalence under the counterfactual scenario of policies held to 1989 levels. Almost half of that 46% reduction is explained by price increases, 14% by smoke-free air laws, 14% by marketing restrictions, 8% by health warnings, 6% by mass media campaigns, and 10% by cessation treatment programs. As a result of the past policies, a total of almost 420,000 (260,000-715,000 deaths had been averted by 2010, increasing to almost 7 million (4.5 million-10.3 million deaths projected by 2050. Comparing future implementation of a set of stricter policies to a scenario with 2010 policies held constant, smoking prevalence by 2050 could be reduced by another 39% (29%-54%, and 1.3 million (0.9 million-2.0 million out of 9 million future premature deaths could be averted.Brazil provides one of the outstanding public health success stories in reducing deaths due to smoking, and serves as a model for other low and middle income nations. However, a set of stricter policies could further reduce

  5. Alcohol control in the news: the politics of media representations of alcohol policy in South Africa.

    2013-10-01

    Media coverage of the "problems" associated with alcohol is widespread in countries of the global North and now, increasingly, in those of the global South. However, despite this mounting ubiquity, there have been very few analyses either of newspaper coverage of alcohol or of media coverage of alcohol policy, especially outside Europe and North America. This article argues that given international concern with the long-term health, economic, social, and developmental consequences of risky drinking in the global South, an exploration of newspaper coverage of nascent alcohol policy in such a context is both timely and valuable. Indeed, such analyses bring to the fore the deeply contextual and contingent nature of alcohol's problematization in politics, policy, and public life. To examine these assertions, we explore the "attention allocation" processes of two South African alcohol control policies--the Western Cape Liquor Bill and the city of Cape Town's liquor bylaws--in two regional English-language newspapers between 2007 and 2011. In so doing, the article highlights the particularities of the political valence of alcohol in the South African context. Furthermore, it also draws out the tensions between alcohol as a source of livelihoods in a context of endemic unemployment and chronic poverty and alcohol as a causal factor in poverty, crime, violence, and social disintegration. In contrast to media coverage of alcohol policy in Europe and North America, this analysis of the South African press suggests that liquor consumption is far less likely to be framed as an express health risk, forcing us to question how preventative policy efforts should best proceed.

  6. This weapon called peace: The doctrine and strategy of Soviet arms control and disarmament policy

    Energy Technology Data Exchange (ETDEWEB)

    Trifan, D.D.

    1989-01-01

    The strategy of Soviet arms-control and disarmament policy can be summarized in what we have termed the ratchet strategy of peaceful coexistence, in which a strategic advance is achieved through the tactics of multiple and indirect lines of approach, legitimized through invocation of peaceful coexistence, and made permanent and irreversible both by treaties and agreements and by the increasing military capability of the Soviet Union and her allies. This strategy is unchanged from World War II until today. Soviet strategic thought is based on the writings of V. I. Lenin; and both Lenin's strategic concepts and Soviet disarmament and arms-control strategy bear a striking resemblance to the precepts expressed by the 4th-century B.C. Chinese strategist Sun Tzu in the Art of War. This dissertation examines not only the strategic content of this policy, but the doctrinal components of Soviet disarmament and arms control strategy. The doctrinal principles must be derived through examination of: authoritative political and strategic writings, records of negotiations and negotiating positions, treaties and agreements, data concerning weapons systems, and the relationship of these to observed political and strategic developments during the period under examination. The doctrinal principles behind this strategy are: (1) the primary purpose of peaceful coexistence is the undermining of imperialism, (2) any means are permissible in the pursuit of peace strategy, and (3) the motive force for this strategy is Marxist-Leninist ideology, with the ultimate goal being the worldwide imposition of socialism in its Soviet variety. Shifts in Soviet policy are tactical instead of strategic in nature; and in keeping with the Soviet idea of the correlation of forces this strategy can be termed a time-fluid two-player zero-sum game. Consequently, Soviet arms-control and disarmament policy can be a weapon called peace.

    2011-09-01

    The slow progress of tobacco control policy in Japan reflects the tension among the interests of the Finance Ministry (which remains the majority shareholder of Japan Tobacco, Inc), the Health Ministry, tobacco growers and consumers. We sought to examine regional disparities in compliance with national tobacco control legislation (the 2003 Health Promotion Law). Specifically, we sought to examine whether prefecture-level compliance with legislation was correlated with decreases in smoking prevalence, and decreases in lung cancer mortality rates. We also examined whether prefectural involvement in growing tobacco was associated with lower compliance with the law. From 2001 to 2007, higher prefectural compliance with tobacco control laws was associated with decreased prevalence of smoking. Decreased tobacco consumption was in turn associated with declining lung cancer mortality. Prefectures involved in growing tobacco exhibited lower levels of compliance with national tobacco control laws. The same prefectures also exhibited the worst improvement in smoking prevalence. This study in Japan suggests that tobacco control policies are being unevenly implemented across prefectures, and that measures to counteract the influence of local tobacco culture are required to reduce the disparities in regional tobacco control outcomes in that country.

    We examined the effect of tobacco control policies in Mexico on smoking prevalence and smoking-related deaths using the Mexico SimSmoke model. The model is based on the previously developed SimSmoke simulation model of tobacco control policy, and uses population size, smoking rates and tobacco control policy data for Mexico. It assesses, individually, and in combination, the effect of six tobacco control policies on smoking prevalence and smoking-related deaths. Policies included: cigarette excise taxes, smoke-free laws, anti-smoking public education campaigns, marketing restrictions, access to tobacco cessation treatments and enforcement against tobacco sales youth. The model estimates that, if Mexico were to adopt strong tobacco control policies compared to current policy levels, smoking prevalence could be reduced by 30% in the next decade and by 50% by 2053; an additional 470,000 smoking-related premature deaths could be averted over the next 40 years. The greatest impact on smoking and smoking-related deaths would be achieved by raising excise taxes on cigarettes from 55% to at least 70% of the retail price, followed by strong youth access enforcement and access to cessation treatments. Implementing tobacco control policies in Mexico could reduce smoking prevalence by 50%, and prevent 470,000 smoking-related deaths by 2053.

    High rates of cesarean birth are a significant health care quality issue, and birth centers have shown potential to reduce rates of cesarean birth. Measuring this potential is complicated by lack of randomized trials and limited observational comparisons. Cesarean rates vary by provider type, setting, and clinical and nonclinical characteristics of women, but our understanding of these dynamics is incomplete. We sought to isolate labor setting from other risk factors in order to assess the effect of birth centers on the odds of cesarean birth. We generated low-risk cohorts admitted in labor to hospitals (n = 2527) and birth centers (n = 8776) using secondary data obtained from the American Association of Birth Centers (AABC). All women received prenatal care in the birth center and midwifery care in labor, but some chose hospital admission for labor. Analysis was intent to treat according to site of admission in spontaneous labor. We used propensity score adjustment and multivariable logistic regression to control for cohort differences and measured effect sizes associated with setting. There was a 37% (adjusted odds ratio [OR], 0.63; 95% confidence interval [CI], 0.50-0.79) to 38% (adjusted OR, 0.62; 95% CI, 0.49-0.79) decreased odds of cesarean in the birth center cohort and a remarkably low overall cesarean rate of less than 5% in both cohorts. These findings suggest that low rates of cesarean in birth centers are not attributable to labor setting alone. The entire birth center care model, including prenatal preparation and relationship-based midwifery care, should be studied, promoted, and implemented by policy makers interested in achieving appropriate cesarean rates in the United States. © 2016 by the American College of Nurse-Midwives.

    Full Text Available Background. Low birth weight is the single most important factor that determines the chances of child survival. A recent annual estimation indicated that nearly 8 million infants are born with low birth weight in India. The infant mortality rate is about 20 times greater for all low birth weight babies. Methods. A matched case–control study was conducted on 130 low birth weight babies and 130 controls for 12 months (from August 1, 2007, to July 31, 2008 at the Central Referral Hospital, Tadong, East District of Sikkim, India. Data were analyzed using the Statistical Package for Social Sciences, version 10.0 for Windows. Chi-square test and multiple logistic regression were applied. A P value less than .05 was considered as significant. Results. In the first phase of this study, 711 newborn babies, borne by 680 mothers, were screened at the Central Referral Hospital of Sikkim during the 1-year study period, and the proportion of low birth weight babies was determined to be 130 (18.3%. Conclusion. Multiple logistic regression analysis, conducted in the second phase, revealed that low or middle socioeconomic status, maternal underweight, twin pregnancy, previous history of delivery of low birth weight babies, smoking and consumption of alcohol during pregnancy, and congenital anomalies had independent significant association with low birth weight in this study population.

    Full Text Available OBJECTIVE: Racism is related to policies preferences and behaviors that adversely affect blacks and appear related to a fear of blacks (e.g., increased policing, death penalty. This study examined whether racism is also related to gun ownership and opposition to gun controls in US whites. METHOD: The most recent data from the American National Election Study, a large representative US sample, was used to test relationships between racism, gun ownership, and opposition to gun control in US whites. Explanatory variables known to be related to gun ownership and gun control opposition (i.e., age, gender, education, income, conservatism, anti-government sentiment, southern vs. other states, political identification were entered in logistic regression models, along with measures of racism, and the stereotype of blacks as violent. Outcome variables included; having a gun in the home, opposition to bans on handguns in the home, support for permits to carry concealed handguns. RESULTS: After accounting for all explanatory variables, logistic regressions found that for each 1 point increase in symbolic racism there was a 50% increase in the odds of having a gun at home. After also accounting for having a gun in the home, there was still a 28% increase in support for permits to carry concealed handguns, for each one point increase in symbolic racism. The relationship between symbolic racism and opposition to banning handguns in the home (OR1.27 CI 1.03,1.58 was reduced to non-significant after accounting for having a gun in the home (OR1.17 CI.94,1.46, which likely represents self-interest in retaining property (guns. CONCLUSIONS: Symbolic racism was related to having a gun in the home and opposition to gun control policies in US whites. The findings help explain US whites' paradoxical attitudes towards gun ownership and gun control. Such attitudes may adversely influence US gun control policy debates and decisions.

    1991-12-01

    A survey of the characteristics of traditional birth attendants in Krabi Province, Thailand, where the incidence rate of tetanus neonatorum was the highest in the country, was conducted in order to obtain background information necessary for planning a training curriculum and to evaluate previous training courses. Five second year medical students were used as research assistants. After the questionnaire was constructed and tested, the students went to visit a sample of 116 traditional birth attendants (TBAs) to interview them about their personal backgrounds, techniques and practices in delivery and beliefs and attitudes towards midwifery. The study revealed that these TBAs were a mixture of Buddhist and Islamic females whose literacy rate was 53 percent. Ninety-one per cent knew about the availability of an injection for antenatal care at the health center, but only about half knew that it was for tetanus prevention. More than half provided antenatal care at their own home but 85 per cent conducted delivery at the client's home. About eighty per cent of the TBAs claimed that sterilization of instruments was performed. However, dressing of the umbilical cord was done inappropriately using various kinds of powders by about 40 per cent. The majority of TBAs had experience with complicated labors but only 30 per cent were referred, perhaps, due to excessive self-confidence and supernatural beliefs. The trained TBAs possessed a higher level of knowledge of immunization and sterile techniques for cord cutting and dressing of the stumps of the umbilical cord than the untrained group. However, knowledge of sterilization of instruments was not significantly different, indicating a need to improve teaching in this area.(ABSTRACT TRUNCATED AT 250 WORDS)

    Ramanujam, Padma

    1999-08-01

    Public concern over the state of the environment has grown over the past decade. All indications are that this concern will continue to influence policy making into the foreseeable future. Road transport is seen as the major contributor to environmental degradation. Transportation planners around the world face the question: cleaner air and/or faster commutes? While individual vehicles can be made more environmentally friendly, the sheer scale of growth in world-wide vehicle numbers is projected to cause significant environmental degradation in the longer run, and in the absence of newer and stricter polices. It is a challenge for governments to find policies that ensure congestion-free metropolitan areas while guaranteeing both critical environmental quality levels and a sufficient infrastructure access to all groups involved. The objective of the dissertation is to provide a mathematical framework to study transportation policy models for the purpose of controlling congestion and pollution. Towards this objective. a series of transportation policy models are developed to study travel behavior and to quantity the reductions in congestion and automobile emissions. The dissertation begins with a brief historical overview of some of the pioneering works in urban transportation economics and later presents the theoretical foundation for the transportation policy models developed. The dissertation introduces single modal and multimodal transportation network policy models that accomplish road pricing with the imposition of goal targets on link loads. as well as, integrated traffic equilibrium models with marketable mobile emission permits. Furthermore, equilibrium conditions are derived for each model, and both qualitative analysis and computational procedures are studied. Finally, the dissertation concludes with a comparative study of the relationship between regulatory pricing models and marketable emission permit transportation models and a discussion on key factors

    This article is a theoretical-reflexive study that aims to discuss the development and changes in the quality of healthcare assistance to the patient over the years in Brazil, in light of the policies of control and prevention of Healthcare-associated Infection (HAI). Aspects of HAI and the process of change in health policy in Brazil, as well as the quality of assistance associated with its control, are approached in relation to policies of patient safety. There are various new theoretical and practical proposals created in Brazil. In spite of the difficulty of measuring patient safety, directed to the prevention and control of HAI, we emphasize that to only create policies and establish norms, guidelines, and indicators is not sufficient. If no structural support or conditions exist for interventions in the practices of healthcare professionals, aiming at results in acceptable levels, the control of HAI will not be achieved. Resumo Trata-se um estudo teórico-reflexivo, que objetiva discutir a evolução e as mudanças na qualidade da assistência ao paciente, ao longo dos anos no Brasil, à luz das políticas de controle e prevenção da Infecção Relacionada à Assistência à Saúde (IRAS). Aspectos sobre IRAS e o processo de mudança nas políticas de saúde no Brasil, bem como a qualidade da assistência associada ao seu controle, são abordados em relação às políticas de segurança do paciente. Há novas e várias propostas teóricas e práticas criadas no Brasil. Apesar da dificuldade de medir a segurança do paciente, direcionada à prevenção e controle das IRAS, enfatiza-se que somente criar políticas, estabelecer normas, diretrizes e indicadores não são suficientes. Se não houver suporte de estrutura e condições para as intervenções nas práticas dos profissionais na assistência prestada ao paciente, visando resultados em níveis aceitáveis, o controle das IRAS não será alcançado.

    To compare the effect of two lipid emulsions on the development of retinopathy of prematurity in very low birth weight infants. Randomized controlled study. Eighty very low birth weight infants receiving parenteral nutrition from the first day of life were evaluated. One of the two lipid emulsions were used in the study infants: Group 1 (n=40) received fish-oil based lipid emulsion (SmofLipid®) and Group 2 (n=40) soybean oil based lipid emulsion (Intralipid®). The development of retinopathy of prematurity and the need for laser photocoagulation were assessed. The maternal and perinatal characteristics were similar in both groups. The median (range) duration of parenteral nutrition [14days (10-28) vs 14 (10-21)] and hospitalization [34days (20-64) vs 34 (21-53)] did not differ between the groups. Laboratory data including complete blood count, triglyceride level, liver and kidney function tests recorded before and after parenteral nutrition also did not differ between the two groups. In Group 1, two patients (5.0%) and in Group 2, 13 patients (32.5%) were diagnosed with retinopathy of prematurity (OR: 9.1, 95% CI 1.9-43.8, p=0.004). One patient in each group needed laser photocoagulation, without significant difference. Multivariate analysis showed that only receiving fish-oil emulsion in parenteral nutrition decreased the risk of development of retinopathy of prematurity [OR: 0.76, 95% CI (0.06-0.911), p=0.04]. Premature infants with very low birth weight receiving an intravenous fat emulsion containing fish oil developed less retinopathy of prematurity. Copyright © 2013 Elsevier Ltd. All rights reserved.

    This study examined the effectiveness of hospital-based Video Interaction Guidance (VIG; Eliëns, 2010; Kennedy, Landor, & Todd, 2011) for mothers and fathers of infants born preterm (25-37 weeks of gestation). VIG is a preventive video-feedback intervention to support the parent-infant relationship. One hundred fifty families (150 infants, 150 mothers, 144 fathers) participated in a pragmatic randomized controlled trial to evaluate the effects of VIG as adjunct to standard hospital care. Primary outcome was parental interactive behavior (sensitivity, intrusiveness, and withdrawal) as observed in videotaped dyadic parent-infant interaction. Secondary outcomes comprised parental bonding, stress responses, and psychological well-being based on self-report. The intervention effects were assessed at baseline, mid-intervention, 3-week, 3-month, and 6-month follow-ups. Data were analyzed on an intention-to-treat basis, using multilevel modeling and analyses of covariance. VIG proved to be effective in enhancing sensitive behavior and diminishing withdrawn behavior in mothers (Cohen's d range = .24-.44) and in fathers (d range: .54-.60). The positive effects of VIG were particularly found in mothers who experienced the preterm birth as very traumatic (d range = .80-1.04). The intervention, however, did not change parents' intrusive behavior. Analyses additionally revealed positive effects on parental bonding, especially for fathers, yet no significant effects on stress and well-being were detected. The results indicate that VIG is a useful addition to standard hospital care, reducing the possible negative impact of preterm birth on the parent-infant relationship. VIG appeared particularly beneficial for fathers, and for mothers with traumatic birth experiences. High levels of parental intrusiveness, however, need complementary intervention.

    Maternal exposure to environmental tobacco smoke (ETS) is a major health hazard as it contains lower doses of the toxins that smokers' inhale. Prenatal exposure to wood fuel smoke has been linked to delivering low birth weight (LBW) infants. The study aims to assess the association between prenatal exposure to ETS and wood fuel smoke and LBW. A case-control study in ratio 1:1 was conducted in two hospitals with obstetric services in Gaza Strip. Subjects were selected during May-June and July-August 2007 from attenders of Mbarak Hospital and Shifa Medical Centre, respectively. 184 (41.2%), and 79 (17.7%) out of 446 participants were exposed to environmental tobacco smoke and wood fuel smoke, respectively. Adjusted maternal exposure to ETS (especially the number of cigarettes smoked, water pipe and wood fuel smoke) was associated with LBW infants. Cigarette smoke exhibits an independent dose-response risk of LBW after adjusting for confounders. Prenatal exposure to cigarette smoke indoors is related to a reduction in birth weight of infants of -237 g (95% CI: -415, -58) for pregnant women exposed to 1-20 cigarettes per day and -391 g (95% CI: -642, -140) for exposure to more than 20 cigarettes per day. Exposure to wood fuel smoke exhibits a reduction of infants' adjusted mean birth weight by -186 g (95% CI: -354, -19). Prenatal exposure to passive smoking and wood fuel smoke are independently associated with LBW. Both these factors are modifiable exposures that could possibly lead to a reduction of delivering LBW infants.

    2014-06-01

    Control engineering offers a systematic and efficient method to optimize the effectiveness of individually tailored treatment and prevention policies known as adaptive or "just-in-time" behavioral interventions. The nature of these interventions requires assigning dosages at categorical levels, which has been addressed in prior work using Mixed Logical Dynamical (MLD)-based hybrid model predictive control (HMPC) schemes. However, certain requirements of adaptive behavioral interventions that involve sequential decision making have not been comprehensively explored in the literature. This paper presents an extension of the traditional MLD framework for HMPC by representing the requirements of sequential decision policies as mixed-integer linear constraints. This is accomplished with user-specified dosage sequence tables, manipulation of one input at a time, and a switching time strategy for assigning dosages at time intervals less frequent than the measurement sampling interval. A model developed for a gestational weight gain (GWG) intervention is used to illustrate the generation of these sequential decision policies and their effectiveness for implementing adaptive behavioral interventions involving multiple components.

    A method includes generating at least one access vector associated with a specified device in an industrial process control and automation system. The specified device has one of multiple device roles. The at least one access vector is generated based on one or more communication policies defining communications between one or more pairs of devices roles in the industrial process control and automation system, where each pair of device roles includes the device role of the specified device. The method also includes providing the at least one access vector to at least one of the specified device and one or more other devices in the industrial process control and automation system in order to control communications to or from the specified device.

  7. Harmonisation of European Migration Policies: The Failure of Immigration Control Policies in the Seventh and Eighth Decades of the 20th Century

    Directory of Open Access Journals (Sweden)

    Milan Mesić

    2003-12-01

    Full Text Available Until the middle of the 1970s, the migration policies of developed European countries were based on the assumption that controlling immigration was possible. Due to various reasons discussed in this article, such policies proved unsuccessful. The result was an increase in the total number of foreigners and a change in the composition of immigrant communities, i.e. the proportion of supported family members increased. During the 1980s there was increasing convergence in the migration policies of European immigration countries and traditional overseas emigration countries. Policies were more and more oriented towards preventing illegal migration flows, on regulating refugee flows and on balancing labour migration with family migration. The turning-point in the direction of “harmonising” West European migration policies was marked by the Schengen agreement (1985 on gradual elimination of border controls between the signing parties (France, Germany and the Benelux countries. Fear in the face of a possible invasion of Eastern Europeans after the collapse of socialism in 1989 was a further strong stimulus towards the harmonisation of migration policies in the developing EU. As opposed to migration control, the integration of immigrants has remained so far the prerogative of nation-states. The text further presents an overview of migration policy reforms in individual member states of the EU and of multilateral actions. The post-1989 migration regime in Europe has four major traits: 1 an extension of the agenda; 2 an accent on joint actions; 3 defensiveness; 4 confusion and an overload of issues. While on the one hand the EU continues to seek ways of protecting itself from undesired external migration, on the other hand the process of regional integration continues to “erase” its internal borders.

    Full Text Available Several control policies of Q-car 2-DOF semiactive system, namely skyhook, groundhook and hybrid controls are presented. Their ride comfort, suspension displacement and road-holding performances are analyzed and compared with passive system. The analysis covers both transient and steady state responses in time domain and transmissibility response in frequency domain. The results show that the hybrid control policy yields better comfort than a passive suspension, without reducing the road-holding quality or increasing the suspension displacement for typical passenger cars. The hybrid control policy is also shown to be a better compromise between comfort, road-holding and suspension displacement than the skyhook and groundhook control policies.

    Full Text Available BACKGROUND: The Shanghai Public Places Smoking Control Legislation was implemented in March 2010 as the first provincial-level legislation promoting smoke-free public places in China. OBJECTIVE: To evaluate the compliance with this policy as well as its impact on exposure to secondhand smoke (SHS, respiratory symptoms, and related attitudes among employees in five kinds of workplaces (schools, kindergartens, hospitals, hotels, and shopping malls. METHODS: A cross-sectional survey was conducted six months before and then six months after the policy was implemented. Five types of occupational employees from 52 work settings were surveyed anonymously using multistage stratified cluster sampling. RESULTS: Six months after implementation, 82% of the participants agreed that "legislation is enforced most of the time". The percentage of self-reported exposure to secondhand smoke declined from round up to 49% to 36%. High compliance rates were achieved in schools and kindergartens (above 90%, with less compliance in hotels and shopping malls (about 70%. Accordingly, prevalence of exposure to SHS was low in schools and kindergartens (less than 10% and high in hotels and shopping malls (40% and above. The prevalence of respiratory and sensory symptoms (e.g., red or irritated eyes among employees decreased from 83% to 67%. CONCLUSIONS: Initial positive effects were achieved after the implementation of Shanghai Smoking Control legislation including decreased exposure to SHS. However, compliance with the policies was a considerable problem in some settings. Further evaluation of such policy implementation should be conducted to inform strategies for increasing compliance in the future.

    The aim of the study was to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating the efficacy of personalized nutrition guidance on birth rate of fetal macrosomia in the pooled studies. A comprehensive search was conducted to identify all eligible studies using the databases of PubMed, MEDLINE, Embase, Wanfang, Chongqing Weipu Database for Chinese Technical Periodicals and China National Knowledge Infrastructure and reference lists of relevant articles. The methodological quality of the included trials was assessed based on the Jadad scale. We used risk ratios (RRs) to assess the strength of the association, and 95 % confidence intervals (CIs) to evaluate the precision of the estimate. Heterogeneity, publication bias, and sensitivity analysis were also explored. A total of nine RCT studies, including 7,458 pregnant women, were included in the present meta-analysis. The overall results showed that personalized nutrition guidance significantly reduced the birth rate of fetal macrosomia (RR 0.289, 95 % CI 0.184-0.453, P macrosomia. However, due to the limited number of RCTs, especially those with large sample size and multicenter that were quantitatively insufficient, further studies of high quality are required.

    Metformin is suggested to reduce pregnancy complications in women with polycystic ovary syndrome (PCOS). Metformin crosses the placenta and therapeutic concentrations are measured in the fetal circulation. Whether metformin treatment in pregnant PCOS women affects maternal and fetal insulin concentrations at birth is not clarified. To investigate the possible effect of metformin on insulin concentrations in umbilical cord blood and the possible association between maternal and fetal insulin concentrations. Post-hoc analysis of a subgroup of PCOS women participating in a double-blind randomized controlled trial. University hospital setting. Women with PCOS (n=118), aged 19-39 years. Maternal and umbilical cord insulin concentrations immediately after birth. At delivery women randomized to metformin had lower insulin concentrations than those randomized to placebo (259±209 vs 361±261 pmol/l; P=0.020). No difference was found in insulin concentrations in umbilical venous (P=0.95) and arterial (P=0.39) blood between the metformin and placebo groups. The arteriovenous difference was also equal between the groups (P=0.38). Insulin concentrations were higher in the umbilical vein than in the umbilical artery independent of randomization (70±51 vs 45±48 pmol/l; Pmetformin treatment during pregnancy resulted in lower maternal insulin concentrations at delivery. Metformin treatment did not affect fetal insulin concentrations. Higher insulin concentrations in the umbilical vein indicate that the placenta somehow secretes insulin to the fetus. The possibility of placental insulin secretion to the fetus deserves further investigations.

    The aim is to extend understanding of the policy and practice discourses that inform the development of national tobacco control policy to protect children from secondhand smoke exposure (SHSE) in the home, particularly in a country with successful implementation of smoke-free public places legislation. The Scottish experience will contribute to the tobacco control community, particularly those countries at a similar level of tobacco control, as normalising discourses about protecting children from SHSE are becoming more widespread. Case study design using qualitative interviews and focus groups (FGs) with policy makers, health and childcare practitioners during which they were presented with the findings of the Reducing Families' Exposure to Secondhand Smoke (REFRESH) intervention and discussed the implications for their policy and practice priorities. Scotland, UK PARTICIPANTS: Qualitative interviews and FGs were conducted with 30 policy makers and practitioners who were purposively recruited. Participants accepted the harm of SHSE to children; however, action is limited by political expedience due to-the perception of a shift of the public health priority from smoking to alcohol, current financial constraints, more immediate child protection concerns and continuing unresolved ethical arguments. In a country, such as Scotland, with advanced tobacco control strategies, there continue to be challenges to policy and practice development in the more contentious arena of the home. Children's SHSE in their homes is unequivocally accepted as an important health priority, but it is not currently perceived to be a top public health priority in Scotland.

    Multiple congenital abnormalities are caused by chromosomal aberrations, mutant major genes and teratogens. A minor proportion of these patients are identified as syndromes but the major part belonging to the group of unclassified multiple CAs (UMCAs). The main objective of this study was to evaluate the maternal age and birth order in pregnant women who had offspring affected with UMCA. The strong association between numerical chromosomal aberrations, e.g., Down syndrome and advanced maternal age is well-known and tested here. The Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980 to 1996, yielded a large population-based national data set with 22,843 malformed newborns or fetuses ("informative cases") included 1349 UMCA cases with their 2407 matched controls. Case-control comparison of maternal age and birth order was made for cases with UMCA, stratified by component numbers and their controls. In addition, 834 cases with Down syndrome were compared to 1432 matched controls. The well-known advanced maternal age with the higher risk for Down syndrome was confirmed. The findings of the study suggest that the young age of mothers associates with the higher risk of UMCA, in addition birth order 4 or more associates with the higher risk for UMCA with 2 and 3 component CAs. This study was the first to analyze the possible maternal and birth order effect for cases with UMCA, and the young age and higher birth order associated with a higher risk for UMCA. © 2014 Wiley Periodicals, Inc.

    Evidence-based policies encouraging healthy behaviours are often strongly opposed by well-funded industry groups. As public support is crucial for policy change, public health advocates need to be equipped with strategies to offset the impact of anti-policy messages. In this study, we aimed to investigate the effectiveness of theory-based public health advocacy messages in generating public support for sugary drink/alcohol policies (increased taxes; sport sponsorship bans) and improving resistance to subsequent anti-policy messages typical of the sugary drink/alcohol industry. We conducted a two-wave randomised online experiment assigning Australian adults to one of four health policies (sugary drink tax; sugary drink industry sports sponsorship ban; alcohol tax; alcohol industry sports sponsorship ban). Within each health policy, we randomised participants to one of five message conditions: (i) non-advocacy based message about the size and seriousness of the relevant health issue (control); (ii) standard pro-policy arguments alone; (iii) standard pro-policy arguments combined with an inoculation message (forewarning and directly refuting anti-policy arguments from the opposition); (iv) standard pro-policy arguments combined with a narrative message (a short, personal story about an individual's experience of the health issue); or (v) standard pro-policy arguments combined with a composite inoculation and narrative message. At time 1, we exposed participants (n = 6000) to their randomly assigned message. Around two weeks later, we re-contacted participants (n = 3285) and exposed them to an anti-policy message described as being from a representative of the sugary drink/alcohol industry. Generalised linear models tested for differences between conditions in policy support and anti-industry beliefs at both time points. Only the standard argument plus narrative message increased policy support relative to control at time 1. The standard argument plus narrative

    Full Text Available Aim: Policymaking in Vietnam has traditionally been the preserve of the political elite, not open to the scrutiny of those outside the Communist Party. This paper aims to analyse Vietnam's HIV policy development in order to describe and understand the policy content, policy-making processes, actors and obstacles to policy implementation. Methods: Nine policy documents on HIV were analysed and 17 key informant interviews were conducted in Hanoi and Quang Ninh Province, based on a predesigned interview guide. Framework analysis, a type of qualitative content analysis, was applied for data analysis. Results: Our main finding was that during the last two decades, developments in HIV policy in Vietnam were driven in a top-down way by the state organs, with support and resources coming from international agencies. Four major themes were identified: HIV policy content, the policy-making processes, the actors involved and human resources for policy implementation. Vietnam's HIV policy has evolved from one focused on punitive control measures to a more rights-based approach, encompassing harm reduction and payment of health insurance for medical costs of patients with HIV-related illness. Low salaries and staff reluctance to work with patients, many of whom are drug users and female sex workers, were described as the main barriers to low health staff motivation. Conclusion: Health policy analysis approaches can be applied in a traditional one party state and can demonstrate how similar policy changes take place, as those found in pluralistic societies, but through more top-down and somewhat hidden processes. Enhanced participation of other actors, like civil society in the policy process, is likely to contribute to policy formulation and implementation that meets the diverse needs and concerns of its population.

    Excessive demands on maternal nutritional status may be a risk factor for poor birth outcomes. This study examined the association between breastfeeding during late pregnancy (≥ 28 weeks) and the risk of having a small-for-gestational-age (SGA) newborn, using a matched case-control design (78 SGA cases: birthweight <10th percentile for gestational age; 150 non-SGA controls: 50th percentile controls based on hospital, gestational age, and inter-gestational period. Mothers were interviewed and clinical chart extractions were completed. Factors associated with risk of SGA were assessed by their adjusted odds ratios (aOR) from conditional logistic regression. Exposure to an overlap of breastfeeding during late pregnancy was not associated with an increased risk of having a SGA newborn [aOR=0.58, 95% confidence interval (CI): 0.10-3.30]. However, increased risk was associated with having a previous low-birthweight birth (aOR=6.53; 95% CI: 1.43-29.70) and a low intake of animal source foods (<25th percentile; aOR=2.26; 95% CI: 1.01-5.04), and tended to be associated with being short (<150 cm; aOR=2.05; 95% CI: 0.92-4.54). This study found no evidence to support the hypothesis that breastfeeding during late pregnancy increases the risk for SGA; however, studies with greater statistical power are needed to definitively examine this possible association and clarify whether there are other risks to the new baby, the toddler and the pregnant woman. © 2012 Blackwell Publishing Ltd.

    The promotion of healthy eating and physical activity within school settings is an important component of population-based strategies to prevent obesity; however, adolescents may be vulnerable to weight-related messages, as rapid development during this life stage often leads to preoccupation with body size and shape. This study examines secular trends in secondary school curricula topics relevant to the prevention of unhealthy weight-control behaviors; describes cross-sectional associations between weight-related curricula content and students' use of weight-control behaviors; and assesses whether implementation of school-based obesity-prevention policies/practices is longitudinally related to students' weight-control behaviors. The Minnesota School Health Profiles and Minnesota Student Survey (grades 9 and 12) data were used along with National Center for Education Statistics data to examine secular trends, cross-sectional associations (n=141 schools), and longitudinal associations (n=42 schools). Students self-reported their height and weight along with past-year use of healthy (eg, exercise), unhealthy (eg, fasting), and extreme (eg, use laxatives) weight-control behaviors. Descriptive statistics, generalized estimating equations, and generalized linear regression models accounting for school-level demographics. There was no observable pattern during the years 2008 to 2014 in the mean number of curricula topics addressing unhealthy weight-control behaviors, despite an increase in the prevalence of curricula addressing acceptance of body-size differences. Including three vs fewer weight-control topics and specifically including the topic of eating disorders in the curricula was related to a lower school-level percent of students using any extreme weight-control behaviors. In contrast, an overall measure of implementing school-based obesity-prevention policies/practices (eg, prohibited advertising) was unrelated to use of unhealthy or extreme behaviors

    Full Text Available Preparing consolidated financial statements has been a common practice for groups of companies around the world for a relatively long time, going back one century in the USA and tens of years in different European countries.A far-reaching issue regarding consolidation accounting policy is the concept of control, as it holds a crucial role in determining the basis of consolidation and the applicable method of consolidation and subsequently in influencing the content of the group financial statements. We focus in our article on the concept of exclusive control as it is approached by the relevant International, American and European standards, casting light also on possible future developments of this concept. The objective of our study is to acknowledge the differences and similarities between the approaches to the control concept, closing with the presentation of the influences of these approaches on the basis of consolidation.

    To investigate the association between the genetic polymorphism of 2',5'-oligoadenylate synthetase 1 (OAS1) and susceptibility to spontaneous preterm birth (SPTB) and preterm premature rupture of membranes (PPROM). The case-control study consisted of 599 preterm infants including 171 cases of PPROM, and 673 full-term infants without maternal histories of SPTB and PPROM as controls. The single nucleotide polymorphism (SNP) at OAS1 intron 5, rs10774671, was analyzed by polymerase chain reaction-restriction fragment length polymorphism. No significant differences were observed between the case and control groups in the frequencies of genotypes (AA, GA, and GG) and alleles (A and G) of OAS1 rs10774671. When the case group was divided into two subgroups with or without PPROM, no significant differences in the genotype and allele frequencies were found between each subgroup and the control group. When the case group was divided into three subgroups with different gestational ages at SPTB, no significant differences in the genotype and allele frequencies were detected between each subgroup and the control group. No association is identified between OAS1 SNP and susceptibility to SPTB and PPROM.

    Multidrug-resistant tuberculosis (MDR-TB) challenges TB control efforts because of delays in diagnosis plus its long-term treatment which has toxic effects. Of TB high-incidence countries, India carries the highest burden of MDR-TB cases. We describe policy issues in India concerning MDR-TB diagnosis and management in a careful review of the literature including a systematic review of studies on the prevalence of MDR-TB. Of 995 articles published during 2001-2016 and retrieved from the PubMed, only 20 provided data on the population prevalence of MDR-TB. We further reviewed and describe diagnostic criteria and treatment algorithms in use and endorsed by the Revised National TB Control Program of India. We discuss problems encountered in treating MDR-TB patients with standardized regimens. Finally, we provide realistic suggestions for policymakers and program planners to improve the management and control of MDR-TB in India.Journal of Public Health Policy advance online publication, 6 May 2016; doi:10.1057/jphp.2016.14.

    Full Text Available BACKGROUND: There is strong evidence that sensory experience in early life has a profound influence on the development of sensory circuits. Very little is known, however, about the role of experience in the early development of striatal networks which regulate both motor and cognitive function. To address this, we have investigated the influence of early environmental enrichment on motor development. METHODOLOGY/PRINCIPAL FINDINGS: Mice were raised in standard or enriched housing from birth. For animals assessed as adults, half of the mice had their rearing condition reversed at weaning to enable the examination of the effects of pre- versus post-weaning enrichment. We found that exclusively pre-weaning enrichment significantly improved performance on the Morris water maze compared to non-enriched mice. The effects of early enrichment on the emergence of motor programs were assessed by performing behavioural tests at postnatal day 10. Enriched mice traversed a significantly larger region of the test arena in an open-field test and had improved swimming ability compared to non-enriched cohorts. A potential cellular correlate of these changes was investigated using Wisteria-floribunda agglutinin (WFA staining to mark chondroitin-sulfate proteoglycans (CSPGs. We found that the previously reported transition of CSPG staining from striosome-associated clouds to matrix-associated perineuronal nets (PNNs is accelerated in enriched mice. CONCLUSIONS/SIGNIFICANCE: This is the first demonstration that the early emergence of exploratory as well as coordinated movement is sensitive to experience. These behavioural changes are correlated with an acceleration of the emergence of striatal PNNs suggesting that they may consolidate the neural circuits underlying these behaviours. Finally, we confirm that pre-weaning experience can lead to life long changes in the learning ability of mice.

    Objective We examine disparities in birth weight and gestational age by ethnic ancestry in 2000–2011 in eight South American countries. Methods The sample included 60480 singleton live-births. Regression models were estimated to evaluate differences in birth outcomes by ethnic ancestry controlling for time trends. Results Significant disparities were found in seven countries. In four countries – Brazil, Ecuador, Uruguay, and Venezuela – we found significant disparities in both low birth weight and preterm birth. Disparities in preterm birth alone were observed in Argentina, Bolivia, and Colombia. Several differences in continuous birth weight, gestational age, and fetal growth rate were also observed. There were no systematic patterns of disparities between the evaluated ethnic ancestry groups across the study countries, in that no racial/ethnic group consistently had the best or worst outcomes in all countries. Conclusions Racial/ethnic disparities in infant health are common in several South American countries. Differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms. Researchers and policymakers should acknowledge these disparities and develop research and policy programs to effectively target them. PMID:25542227

    The harmful effects of heavy drinking on health have been widely reported, yet public opinion on governmental responsibility for alcohol control remains divided. This study examines UK public attitudes towards alcohol policies, identifies underlying dimensions that inform these, and relationships with perceived effectiveness. A cross-sectional mixed methods study involving a telephone survey of 3477 adult drinkers aged 16-65 and sixteen focus groups with 89 adult drinkers in Scotland and England was conducted between September 2012 and February 2013. Principal components analysis (PCA) was used to reduce twelve policy statements into underlying dimensions. These dimensions were used in linear regression models examining alcohol policy support by demographics, drinking behaviour and perceptions of UK drinking and government responsibility. Findings were supplemented with a thematic analysis of focus group transcripts. A majority of survey respondents supported all alcohol policies, although the level of support varied by type of policy. Greater enforcement of laws on under-age sales and more police patrolling the streets were strongly supported while support for pricing policies and restricting access to alcohol was more divided. PCA identified four main dimensions underlying support on policies: alcohol availability, provision of health information and treatment services, alcohol pricing, and greater law enforcement. Being female, older, a moderate drinker, and holding a belief that government should do more to reduce alcohol harms were associated with higher support on all policy dimensions. Focus group data revealed findings from the survey may have presented an overly positive level of support on all policies due to differences in perceived policy effectiveness. Perceived effectiveness can help inform underlying patterns of policy support and should be considered in conjunction with standard measures of support in future research on alcohol control policies

    This paper assesses the impact of different spacing policies for Adaptive Cruise Control (ACC) systems on traffic and environment. The largest deal of existing studies focus on assessing the performance in terms of safety, while only few deal with the effect of ACC on the traffic flow and the environment. In particular, very little is know on traffic stability and energy consumption. In this study, the vehicles equipped with ACC are modelled and controlled by two different spacing policies. B...

    Internationally, governments have implemented school-based nutrition policies to restrict the availability of unhealthy foods from sale. The aim of the trial was to assess the effectiveness of a multi-strategic intervention to increase implementation of a state-wide healthy canteen policy. The impact of the intervention on the energy, total fat, and sodium of children's canteen purchases and on schools' canteen revenue was also assessed. Australian primary schools with a canteen were randomised to receive a 12-14-month, multi-strategic intervention or to a no intervention control group. The intervention sought to increase implementation of a state-wide healthy canteen policy which required schools to remove unhealthy items (classified as 'red' or 'banned') from regular sale and encouraged schools to 'fill the menu' with healthy items (classified as 'green'). The intervention strategies included allocation of a support officer to assist with policy implementation, engagement of school principals and parent committees, consensus processes with canteen managers, training, provision of tools and resources, academic detailing, performance feedback, recognition and marketing initiatives. Data were collected at baseline (April to September, 2013) and at completion of the implementation period (November, 2014 to April, 2015). Seventy schools participated in the trial. Relative to control, at follow-up, intervention schools were significantly more likely to have menus without 'red' or 'banned' items (RR = 21.11; 95% CI 3.30 to 147.28; p ≤ 0.01) and to have at least 50% of menu items classified as 'green' (RR = 3.06; 95% CI 1.64 to 5.68; p ≤ 0.01). At follow-up, student purchases from intervention school canteens were significantly lower in total fat (difference = -1.51 g; 95% CI -2.84 to -0.18; p = 0.028) compared to controls, but not in energy (difference = -132.32 kJ; 95% CI -280.99 to 16.34; p = 0.080) or sodium (difference = -46

    Full Text Available OBJECTIVE: To examine how policies adopted in Mexico in response to the Framework Convention on Tobacco Control affected smoking prevalence and smoking-attributable deaths. METHODS: The SimSmoke simulation model of tobacco control policy is applied to Mexico. This discrete time, first-order Markov model uses data on population size, smoking rates and tobacco control policy for Mexico. It assesses, individually and jointly, the effects of seven types of policies: cigarette taxes, smoke-free air laws, mass media campaigns, advertising bans, warning labels, cessation treatment, and youth tobacco access policies. RESULTS: The Mexico SimSmoke model estimates that smoking rates have been reduced by about 30% as a result of policies implemented since 2002, and that the number of smoking-attributable deaths will have been reduced by about 826 000 by 2053. Increases in cigarette prices are responsible for over 60% of the reductions, but health warnings, smoke-free air laws, marketing restrictions and cessation treatments also play important roles. CONCLUSIONS: Mexico has shown steady progress towards reducing smoking prevalence in a short period of time, as have other Latin American countries, such as Brazil, Panama and Uruguay. Tobacco control policies play an important role in continued efforts to reduce tobacco use and associated deaths in Mexico.

    In December 1981 the government of the Republic of Korea announced new population control policy measures calling for an improvement of the current family planning program management system; institution of a new social and institutional support system to inculcate the small size family norm and to eradicate the parental son preference attitude; strengthening information, education, and communication (IEC) activities; and establishment of close coordination among the government organizations relating to the population programs. As a result of the policy measures, since 1982 there has been a rapid increase in the contraceptive acceptance rate. The number of contraceptive acceptors through the government program increased from 614,100 in 1981 to 1,094,600 in 1983, a 78.3% increase. There has been a marked increase in sterilization and menstrual regulation services. The program achievement for 1983 is equivalent to about 19% of the total eligible women aged 15-44. According to the contraceptive acceptors' coupon analysis, the age of women at the time of contraceptive acceptance through the government program dropped steadily from 31.4 in 1981 to 30.2 in 1983 and their number of children declined from 2.8 to 2.5 during the same period. In line with the new population control policy, several social support measures for the small size family have been strengthened. These include: income tax exemption up to 2 children; corporation tax exemption on expenditure for family planning services to employees; inclusion of population education in the formal school curriculum; and reduction of child delivery charges for sterilization acceptors after 2nd delivery in public hospitals. The 1982 National Family Health Survey revealed that the total fertility rate declined to 2.7 and the contraceptive practice rate of women aged 15-44 increased to 58% in 1982. Yet, in recent years virtually no substantial change in the fertility level and in the contraceptive practice rate has been

    This paper presents a single-network adaptive critic-based controller for continuous-time systems with unknown dynamics in a policy iteration (PI) framework. It is assumed that the unknown dynamics can be estimated using the Takagi-Sugeno-Kang fuzzy model with arbitrary precision. The successful implementation of a PI scheme depends on the effective learning of critic network parameters. Network parameters must stabilize the system in each iteration in addition to approximating the critic and the cost. It is found that the critic updates according to the Hamilton-Jacobi-Bellman formulation sometimes lead to the instability of the closed-loop systems. In the proposed work, a novel critic network parameter update scheme is adopted, which not only approximates the critic at current iteration but also provides feasible solutions that keep the policy stable in the next step of training by combining a Lyapunov-based linear matrix inequalities approach with PI. The critic modeling technique presented here is the first of its kind to address this issue. Though multiple literature exists discussing the convergence of PI, however, to the best of our knowledge, there exists no literature, which focuses on the effect of critic network parameters on the convergence. Computational complexity in the proposed algorithm is reduced to the order of (Fz)(n-1) , where n is the fuzzy state dimensionality and Fz is the number of fuzzy zones in the states space. A genetic algorithm toolbox of MATLAB is used for searching stable parameters while minimizing the training error. The proposed algorithm also provides a way to solve for the initial stable control policy in the PI scheme. The algorithm is validated through real-time experiment on a commercial robotic manipulator. Results show that the algorithm successfully finds stable critic network parameters in real time for a highly nonlinear system.

    hepatitis response framework was used to organize the analysis. Ethiopia is in the process of preparing strategic plan and guidelines for viral hepatitis. However, the country still lacks the required partnerships, and resource mobilization as a national health response is limited. Community awareness on the disease transmission and its sequel is poor. Viral hepatitis screening services are not widely available except for the occasional mandatory medical checkups for work or travel purposes. Healthcare providers often take no further action after diagnosing patients with viral hepatitis due to lack of treatment guidelines and strategic frameworks for screening, diagnosis, and treatment. Besides, drugs that are effective in the treatment of viral hepatitis are not available, mainly due to regulatory challenges. Viral hepatitis and its disease burden are getting little attention in Ethiopia and many low-income countries. The levels of technical guidance and financial support from the international community are low. To date, the response to the infections in Ethiopia is patchy. Thus, the country needs to formulate policy and strategies in the areas of disease surveillance, risk group identification and screening, use of the birth dose of hepatitis B vaccine, and care and treatment. Improving availability of data on viral hepatitis, access to low-cost generic drugs and developing and dissemination of treatment guidelines are also critical. Leveraging the successful Health Extension Program for a hepatitis response, and exploring ways to learn from and integrate into the HIV/AIDS program should also be considered.
