2015-04-01

Full Text Available Based on representative survey data, the present study examines potentials for the sustainable development of a transnational civil society in French-German, Polish-German, and Czech-German border regions. The theoretical framework is a social capital approach in the tradition of Putnam. Transnational engagement is seen as a key element for the development of a border-crossing civil society. For the analysis, existing forms of social capital were classified according to their bridging and bonding functions and the potentials of local and transnational activities are described. Furthermore, using multilevel analysis, the predictive power of different variables like individual dispositions and specific contexts of the regions on cross-border activities are examined. Descriptively, the expected lower level of local civil-society engagement, in general, and also with regard to the transnational activities was found for post-socialist border regions. It is shown that, first and foremost, existing experience in civil-society engagement in the local context is a high-impact predictor for both transnational activities and an interest in such activities. Other variables like feelings of a historical burden or the economic situation of the region are less important.

Functional Median Polish

KAUST Repository

Sun, Ying

2012-08-03

This article proposes functional median polish, an extension of univariate median polish, for one-way and two-way functional analysis of variance (ANOVA). The functional median polish estimates the functional grand effect and functional main factor effects based on functional medians in an additive functional ANOVA model assuming no interaction among factors. A functional rank test is used to assess whether the functional main factor effects are significant. The robustness of the functional median polish is demonstrated by comparing its performance with the traditional functional ANOVA fitted by means under different outlier models in simulation studies. The functional median polish is illustrated on various applications in climate science, including one-way and two-way ANOVA when functional data are either curves or images. Specifically, Canadian temperature data, U. S. precipitation observations and outputs of global and regional climate models are considered, which can facilitate the research on the close link between local climate and the occurrence or severity of some diseases and other threats to human health. © 2012 International Biometric Society.

2014-01-01

Since the introduction of robotic technology, there have been significant changes to the field of gynecology. The number of minimally invasive procedures has drastically increased, with robotic procedures rising remarkably. To date several authors have published cost analyses demonstrating that robotic hysterectomy for benign and oncologic indications is more costly compared to the laparoscopic approach. Despite being more expensive than laparoscopy, other studies have found robotics to be less expensive and more effective than laparotomy. In this review, controversies surrounding cost-effectiveness studies are explored. © 2013 The Authors.

Circadian rhythm sleep-wake disorders (CRSWD) are a group of disorders, in which the timing of sleep and wakefulness significantly differs from a patient's expectations or socially acceptable times. The aimof the article is to present the current principles for the diagnosis and treatment of CRSWD in adults and children. Guidelines proposed as CRSWD treatment standard are based on the recommendations from the scientific societies involved in the sleep research and medicine. Researchers participating in the guidelines preparation were invited by the Polish Sleep Research Society and the Section of Biological Psychiatry of the Polish Psychiatric Association based on their significant contribution to the circadian rhythm research and/or clinical experience in the treatment of these disorders. Finally, the guidelines were adjusted to the questions and comments given by the members of both Societies. Patients with endogenous CRSWD are often misdiagnosed and treated for insomnia or hypersomnia. Therefore, each patient reporting sleep-wake disorders should be interviewed about the quality of sleep and its timing during free days (e.g. weekends, holidays). Avalid CRSWD diagnosis can be also established by using sleep diaries/logs and actigraphy. The treatment of choice for CRSWD is chronotherapy, which involves melatonin application, light therapy, and behavioral interventions. Sleep disorders associated with shift work and time zone changes are a growing health problem. Interventions for these disorders should primarily focus on prevention. The main problem in the treatment of CRSWD is an invalid diagnosis. Hypnotics and/or psychostimulants are often used instead of chronotherapeutic interventions, what can alleviate symptoms but is not an effective treatment.

Biological significance of food components suggests that preferences for basic tastes should be similar across cultures. On the other hand, cultural factors play an important role in diet and can consequently influence individual preference for food. To date, very few studies have compared basic tastes preferences among populations of very diverse environmental and cultural conditions, and research rather did not involve traditional populations for whom the biological significance of different food components might be the most pronounced. Hence, our study focused on basic taste preferences in three populations, covering a broad difference in diet due to environmental and cultural conditions, market availability, dietary habits and food acquirement: 1) a modern society (Poles, n = 200), 2) forager-horticulturalists from Amazon/Bolivia (Tsimane', n = 138), and 3) hunter-gatherers from Tanzania (Hadza, n = 85). The preferences for basic tastes were measured with sprays containing supra-threshold levels of sweet, sour, bitter, salty, and umami taste solutions. We observed several interesting differences between participating societies. We found that Tsimane' and Polish participants liked the sweet taste more than other tastes, while Hadza participants liked salty and sour tastes more than the remaining tastes. Further, Polish people found bitter taste particularly aversive, which was not observed in the traditional societies. Interestingly, no cross-cultural differences were observed for relative liking of umami taste - it was rated closely to neutral by members of all participating societies. Additionally, Hadza showed a pattern to like basic tastes that are more common to their current diet than societies with access to different food sources. These findings demonstrate the impact of diet and market availability on preference for basic tastes. Copyright © 2017 Elsevier Ltd. All rights reserved.

Cervical, endometrial, and ovarian cancers, have both high morbidity and mortality among the gynecologic malignant tumors in Japan. The present study was conducted using both the population-based cancer registry and the gynecologic cancer registry to elucidate the characteristics of gynecologic malignant tumors in Japan. Based on nationwide estimates from the population-based cancer registry in Japan, the morbidities and mortality of cervical, endometrial, and ovarian cancers were obtained and used for analysis. Clinicopathologic factors for cervical cancer, endometrial cancer, ovarian cancer, including age, clinical stage, postsurgical stage, histological type, therapeutic strategy, and prognosis were retrieved from the gynecologic cancer registry published by the Japan Society of Obstetrics and Gynecology and used for analysis. The morbidities of cervical, endometrial, and ovarian cancers were 10,908, 13,606, and 9,384 women in 2012, respectively. The prevalence of endometrial cancer has significantly and consistently been increasing and represents the most common gynecologic malignant tumor in Japan. The mortalities of cervical, endometrial, and ovarian cancers were 2.1, 1.3, and 3.2 per 100,000 in 2012, respectively. In 2014, 52.2% of cervical cancer patients were classified as stage I, 22.5% as stage II, 10.2% as stage III, and 11.2% as stage IV. In addition, 71.9% of endometrial cancer patients were classified as stage I, 6.0% as stage II, 13.3% as stage III, and 7.5% as stage IV. Finally, 43.2% of ovarian cancer patients were classified as stage I, 9.1% as stage II, 27.6% as stage III, and 7.2% as stage IV. Twelve-point six percent of ovarian cancer patients received neoadjuvant chemotherapy. PMID:28198168

Majority of the physiological processes in the human organism are rhythmic. The most common are the diurnal changes that repeat roughly every 24 hours, called circadian rhythms. Circadian rhythms disorders have negative influence on human functioning. The aim of this article is to present the current understanding of the circadian rhythms physiological role, with particular emphasis on the circadian rhythm sleep-wake disorders (CRSWD), principles of their diagnosis and chronobiological therapy. The guidelines are based on the review of recommendations from the scientific societies involved in sleep medicine and the clinical experiences of the authors. Researchers participating in the preparation of guidelines were invited by the Polish Sleep Research Society and the Section of Biological Psychiatry of the Polish Psychiatric Association, based on their significant contributions in circadian rhythm research and/or clinical experience in the treatment of such disorders. Finally, the guidelines were adjusted to the questions and comments given by the members of both Societies. CRSWD have a significant negative impact on human health and functioning. Standard methods used to assess CRSWD are sleep diaries and sleep logs, while the actigraphy, when available, should be also used. The most effective methods of CRSWD treatment are melatonin administration and light therapy. Behavioral interventions are also recommended. Afourteen-day period of sleep-wake rhythm assessment in CRSWD enables accurate diagnosis, adequate selection of chronobiological interventions, and planning adequate diurnal timing of their application. This type of assessment is quite easy, low-cost, and provides valuable indications how to adjust the therapeutic approach to the circadian phase of the particular patient.

The Polish Mother on the defensive? The transformation of the myth and its impact on the motherhood of Polish women

Directory of Open Access Journals (Sweden)

Agnieszka Imbierowicz

2012-06-01

Full Text Available The subject of this presentation is the attempt to define and to present the origins, socio-cultural content and the evolution of The Polish Mother myth, present in the polish national consciousness. The author tries to show how this myth was born, what functions it fulfilled and what forms it took in the changing historical and social reality, from the moment of loss of independence, through a period of real socialism, until the present day. The impact of this myth in the lives of real women and their motherhood is taken into consideration. Then, the author comparing the results of the latest polish sociological researches on the family and its transformation, and transformation of value systems together with theories about the specifics of life in the period of postmodernity, wonders whether it’s time to deconstruct the myth of The Polish Mother, because it does not fit the conditions of today’s world, which is characterized, above all, by the apotheosis of individuality, self-realization and freedom, or perhaps in polish society there is still strong traditionalism in thinking about motherhood, and the myth of The Polish Mother is still alive?

This study aimed to determine the publication rate of oral and poster abstracts presented at the 2010 and 2011 Society of Gynecologic Oncology (SGO) conferences as well as the journals that most commonly published these studies, their 5-year impact factor, the time to publication, and the reasons for nonpublication. Abstracts presented at the 2010-2011 SGO conferences were included in this study. We searched Google, Google Scholar, and PubMed to locate published reports of these abstracts. If an abstract's full-text manuscript could not be located, an author of the conference abstract was contacted via email to inquire whether the research was published. If the research was unpublished, the authors were asked to provide the reason for nonpublication. The time to publication, journal, and journal impact factor were noted for abstracts that reached full-text publication. A total of 725 abstracts were identified, of which 386 (53%) reached publication in a peer-reviewed journal. Oral presentations were published at a higher rate than poster presentations. Most (70%) reached publication within 2 years of abstract presentation. Abstracts were published in 89 journals, but most (39%) were published in Gynecologic Oncology. The mean time to publication was 15.7 months, with a mean 5-year impact factor of 4.956. A 53% publication rate indicates that the SGO conference selection process favors research likely to be published and, thus, presumably of high quality. The overall publication rate is higher than that reported for many other biomedical conferences.

The third version of the Japan Society of Gynecologic Oncology guidelines for the treatment of uterine body neoplasms was published in 2013. The guidelines comprise nine chapters and nine algorithms. Each chapter includes a clinical question, recommendations, background, objectives, explanations, and references. This revision was intended to collect up-to-date international evidence. The highlights of this revision are to (1) newly specify costs and conflicts of interest; (2) describe the clinical significance of pelvic lymph node dissection and para-aortic lymphadenectomy, including variant histologic types; (3) describe more clearly the indications for laparoscopic surgery as the standard treatment; (4) provide guidelines for post-treatment hormone replacement therapy; (5) clearly differentiate treatment of advanced or recurrent cancer between the initial treatment and the treatment carried out after the primary operation; (6) collectively describe fertility-sparing therapy for both atypical endometrial hyperplasia and endometrioid adenocarcinoma (corresponding to G1) and newly describe relapse therapy after fertility-preserving treatment; and (7) newly describe the treatment of trophoblastic disease. Overall, the objective of these guidelines is to clearly delineate the standard of care for uterine body neoplasms in Japan with the goal of ensuring a high standard of care for all Japanese women diagnosed with uterine body neoplasms.

Perinatal care in Japan has progressed rapidly in recent decades, remarkably reducing maternal, perinatal and neonatal mortality rates. This is attributable not only to the sustained efforts and dedication of past obstetricians and midwives, but also to the collective results achieved by the Japan Society of Obstetrics and Gynecology and healthcare administration, including research on advanced medical care, education, medical care improvements and establishing perinatal care centers. Although the maternal mortality rate was in steady decline until 2007 (3.1/100 000 births), it repeatedly fluctuated thereafter, plateauing at 3.4 per 100 000 births in 2013 and 2.7 per 100 000 births in 2014. Thus, the Perinatology Committee has analyzed the current situation of maternal deaths and has proposed countermeasures to reduce such death. The items deliberated upon by related subcommittees in 2015 are presented herein. The addition of indications for 'fibrinogen concentrate', 'eptacog alfa' and approval of the PGE2 vaginal tablet for cervical ripening were discussed in the subcommittee for unapproved drug review. Thus, a request for approval for health insurance coverage was submitted to the 'Evaluation committee on unapproved or off-label drugs with high medical needs' of the Ministry of Health, Labour and Welfare. Maternal and late-maternal deaths from suicide during the 10 years from 2005 to 2014 in Tokyo's 23 wards were jointly examined with the Tokyo Medical Examiner's Office. The suicide rate in the 23 wards is very high, at 8.7 per 100 000 births. Thus, the subcommittee for the reduction of maternal death discussed countermeasures for the eradication of maternal death and maternal suicide and the revision of death certificates. © 2017 Japan Society of Obstetrics and Gynecology.

Surgery and radiation therapy have been the main types of treatment for gynecologic cancer. However, chemotherapy in gynecologic oncology has recently made dramatic progress and presently is becoming the most widespread treatment. After the discovery of cisplatin in the field of chemotherapy for epithelial ovarian cancer, it has now become the leading treatment modality. According to the result of several important phase III randomized control trials (RCTs), the platinum-taxane combined therapy has now become the standard treatment regimen. Regarding endometrial cancer, Cisplatin-Adriamycin-Cyclophosphamide (CAP) therapy has been used as an effective adjuvant chemotherapy in Japan. The adjuvant chemotherapy (Adriamycin-Cisplatin therapy) for the endometrial cancer has now been recognized worldwide as the standard therapy based on the findings of a phase III RCT. Concurrent chemoradiotherapy for cervical cancer has also been recommended as the standard therapy in Japan since 1999 based on the successful results of numerous RCTs which proved its efficacy. The chemotherapy for gynecologic cancers has been investigated and standardized based on the results of numerous clinical trials. These trials have been conducted by many clinical trial groups, such as the Gynecologic Oncology Group (GOG), Southwest Oncology Group (SWOG), and the European Organization for Research and Treatment of Cancer (EORTC) throughout the world, in addition to the Japan Clinical Oncology Group (JCOG) and the Japanese Gynecologic Oncology Group (JGOG) in Japan. The valuable contributions of these clinical trials are helping in the development of new drug therapies, thus leading to such treatment regimens playing increasingly important and wider roles in the field of gynecologic oncology treatment in the future.

Here is a story told by Maria Sklodowska-Curie at the meeting of the International Committee of Intellectual Cooperation in 1921: 'In a free literary competition on the role and importance of elephants the Englishman's story was 'My adventures while shooting elephants in South Africa', the Frenchman was more concerned with 'The sexual and erotic life of elephants', while the Polish approach was invariably 'The elephant versus Poland's national independence', which seemed quite understandable in the light of over 120 years when Poland was partitioned and lost its independence. Since then this saying has become proverbial and came to express the unmistakably Polish tendency to see everything in terms of Polish interests. In my remarks and reminiscences on the history of the Polish Society of Medical Physics you will quickly recognize the same tendency. First, I will, among other things, try to open some old cupboards to 'produce good [things] from the store of good' (Matthew 12:35), especially concerning the first few years of the activity in medical physics in Poland, and second, I will draw some conclusions and/or offer suggestions based on what a senior medical physicist has seen for more than 50 years of his activity in this field.

A wide use of imaging techniques results in more frequent diagnosis of adrenal incidenataloma. To analyse the current state of knowledge on adrenal incidentaloma in adults in order to prepare practical management recommendations. Following a discussion, the Polish Society of Endocrinology expert working group have analysed the available data and summarised the analysis results in the form of recommendations. Unenhanced adrenal computed tomography (CT) may be recommended as an initial assessment examination helpful in the differentiation between adenomas and "non-adenomatous" lesions. In the case of density > 10 Hounsfield units, CT with contrast medium washout assessment or MRI are recommended. However, in all patients with adrenal incidentaloma, hormonal assessment is recommended in order to exclude pheochromocytoma and hypercortisolism, notwithstanding the clinical picture or concomitant diseases. In addition, examination to exclude primary hyperaldosteronism is suggested in patients with diagnosed hypertension or hypokalaemia. Surgical treatment should be recommended in patients with adrenal incidentaloma, where imaging examinations suggest a malignant lesion (oncological indication) or with confirmed hormonal activity (endocrinological indication). The basis of the surgical treatment is laparoscopic adrenalectomy. Patients with suspected pheochromocytoma must be pharmacologically prepared prior to surgery. In patients not qualified for surgery, control examinations (imaging and laboratory tests) should be established individually, taking into consideration such features as the size, image, and growth dynamics of the tumour, clinical symptoms, hormonal tests results, and concomitant diseases.

To evaluate the satisfaction with work-life balance (WLB) and career satisfaction of gynecologic oncologists. In August 2014, members of the Society of Gynecologic Oncology (SGO) were sent an anonymous, cross-sectional survey evaluating demographic variables, practice characteristics, career satisfaction, fatigue, and satisfaction with WLB. Fatigue was assessed using a visual-analog scale. Career satisfaction and WLB were assessed with a Likert scale. Inferential statistics were computed with type I error rates of 0.05. Out of the 1002 gynecologic oncologists surveyed, 290 (28.9%) responded. Only 18.6% of respondents were satisfied with WLB and there were significant associations between gender (P = 0.0157), time spent in work related activities at home (P = 0.0024), on weekends (P = 0.0017), and in the hospital (P = 0.0001). More than 84% of physicians reported they would choose medicine as a career again and of those 90% would choose to be a gynecologic oncologist again. Fatigue was strongly associated with dissatisfaction with WLB in univariate and multivariate analysis (P satisfaction may assist the SGO in meeting future gynecologic cancer care needs.

The aim of this article is to propose guidelines and recommendations in problematic areas in pathologic reporting of endometrial carcinoma (EC) regarding special techniques and ancillary studies. An organizing committee designed a comprehensive survey with different questions related to pathologic features, diagnosis, and prognosis of EC that was sent to all members of the International Society of Gynecological Pathologists. The special techniques/ancillary studies group received 4 different questions to be addressed. Five members of the group reviewed the literature and came up with recommendations and an accompanying text which were discussed and agreed upon by all members of the group. Twelve different recommendations are made. They address the value of immunohistochemistry, ploidy, and molecular analysis for assessing prognosis in EC, the value of steroid hormone receptor analysis to predict response to hormone therapy, and parameters regarding applying immunohistochemistry and molecular tests for assessing mismatch deficiency in EC.

Objective To explore the value of multiple clinical endpoints in the unique setting of ovarian cancer. Methods A clinical trial workgroup was established by the Society of Gynecologic Oncology to develop a consensus statement via multiple conference calls, meetings and white paper drafts. Results Clinical trial endpoints have profound effects on late phase clinical trial design, result interpretation, drug development, and regulatory approval of therapeutics. Selection of the optimal clinical trial endpoint is particularly provocative in ovarian cancer where long overall survival (OS) is observed. The lack of new regulatory approvals and the lack of harmony between regulatory bodies globally for ovarian cancer therapeutics are of concern. The advantages and disadvantages of the numerous endpoints available are herein discussed within the unique context of ovarian cancer where both crossover and post-progression therapies potentially uncouple surrogacy between progression-free survival (PFS) and OS, the two most widely supported and utilized endpoints. The roles of patient reported outcomes (PRO) and health related quality of life (HRQoL) are discussed, but even these widely supported parameters are affected by the unique characteristics of ovarian cancer where a significant percentage of patients may be asymptomatic. Original data regarding the endpoint preferences of ovarian cancer advocates is presented. Conclusions Endpoint selection in ovarian cancer clinical trials should reflect the impact on disease burden and unique characteristics of the treatment cohort while reflecting true patient benefit. Both OS and PFS have led to regulatory approvals and are clinically important. OS remains the most objective and accepted endpoint because it is least vulnerable to bias; however, the feasibility of OS in ovarian cancer is compromised by the requirement for large trial size, prolonged time-line for final analysis, and potential for unintended loss of treatment effect

The aim of this report is to present data concerning results and complications related to infertility treatment using assisted reproductive technology (ART) and insemination (IUI) in Poland in 2012. The report was prepared by the Fertility and Sterility Special Interest Group of the Polish Gynaecological Society (SPiN PTG), based on individual data provided by fertility clinics. Reporting was voluntary data were not subject to external verification. The report presents the availability and the structure of infertility treatment services, the number of procedures performed, their effectiveness and the most common complications. In 2014, 34 Polish fertility clinics provided information to the report, presenting data from 2012. The total number of reported treatment cycles using ART was 17,116 (incl. 10,714 fresh IVF/ICSI) and 14,727 IUI. The clinical pregnancy rate per cycle was on average 33.7% for fresh IVF/ICSI and 13.3% for IUI. The prevalence of multiple births was 15.7% and 6.2%, in case of IVF/ICSI and IUI methods respectively The most frequent complication in the course of treatment using ART was ovarian hyperstimulation syndrome (OHSS)--severe OHSS constituted 0.68% of all stimulated cycles. The SPiN PTG report shows the average effectiveness and safety of ART and was the only proof of responsibility and due diligence of fertility centres in Poland. However, due to the lack of a central register of fertility clinics, facultative participation in the report as well as incomplete information on pregnancy and delivery rate, the collected data do not reflect the full spectrum of Polish reproductive medicine.

Tzoneva is being elaborated based on a working Polish-Bulgarian-Russian electronic parallel corpus authored by Maksim Duszkin, Violetta Koseska-Toszewa and Joanna Satoła-Staśkowiak, and works by A. Tzoneva. It is the first corpus comparing languages belonging to three different Slavic language groups: western, southern and eastern. Works on the dictionary are based on Gramatyka konfrontatywna bułgarsko-polska (Bulgarian-Polish confrontative grammar and the proposed there semantic-oriented interlanguage. Two types of classifiers have been introduced into the dictionary: classic and semantic. The trilingual dictionary will present a consistent and homogeneous set of facts of grammar and semantics. The Authors point out that in a traditional dictionary it is not clear for example whether aspect should be understood as imperfective / perfective form of a verb or as its meaning. Therefore in the dictionary forms and meaning are separated in a regular way. Imperfective verb form has two meanings: state and configuration of states and events culminating in state. Also perfective verb form has two meanings: event and configuration of states and events culminating in event. These meanings are described by the semantic classifiers, respectively, state and event, state1 and event1. The way of describing language units, mentioned in the article, gives a possibility to present language material (Polish, Bulgarian, Russian in any required order, hence the article’s title.

Disparities in Gynecological Malignancies

Sudeshna eChatterjee

2016-02-01

Full Text Available Objectives: Health disparities and inequalities in access to care among different socioeconomic, ethnic, and racial groups have been well documented in the U.S. healthcare system. In this review, we aimed to provide an overview of barriers to care contributing to health disparities in gynecological oncology management and to describe site-specific disparities in gynecologic care for endometrial, ovarian, and cervical cancer. Methods: We performed a literature review of peer-reviewed academic and governmental publications focusing on disparities in gynecological care in the United States by searching PubMed and Google Scholar electronic databases. Results: There are multiple important underlying issues that may contribute to the disparities in gynecological oncology management in the United States, namely geographic access and hospital based-discrepancies, research-based discrepancies, influence of socioeconomic and health insurance status, and finally the influence of race and biological factors. Despite the reduction in overall cancer-related deaths since the 1990s, the 5-year survival for Black women is significantly lower than for White women for each gynecologic cancer type and each stage of diagnosis. For ovarian and endometrial cancer, black patients are less likely to receive treatment consistent with evidence-based guidelines and have worse survival outcomes even after accounting for stage and comorbidities. For cervical and endometrial cancer, the mortality rate for black women remains twice that of White women. Conclusions: Health care disparities in the incidence and outcome of gynecologic cancers are complex and involve biologic factors as well as racial, socioeconomic and geographic barriers that influence treatment and survival. These barriers must be addressed to provide optimal care to women in the U.S. with gynecologic cancer.

To determine whether the proportion of leadership positions in obstetrics and gynecology held by women is consistent with expectations based on the proportion of women entering residency at the time of current leaders. Leadership positions were considered as department chairs affiliated with the Council of University Chairs of Obstetrics and Gynecology, editors of the 20 obstetrics and gynecology journals with the highest impact factors [corrected],and presidents of influential professional societies. Publically available data were accessed to determine sex and the year of medical school graduation for each individual holding each leadership position, as well as to determine the number of men and women entering residency in obstetrics and gynecology per year. Actual and expected proportions of leadership positions held by women were compared using χ² tests. Women should hold 71 of the total 194 leadership positions based on the proportion of women entering residency during the mean graduation year among leaders. Women actually hold 41 of these leadership positions (21.1%; Pwomen should hold 28 of these 74 leadership positions. Women actually hold 20 of the leadership positions from this subset (27.0%; P=.05). Women are underrepresented in leadership positions in obstetrics and gynecology, and this cannot be explained by historical sex imbalances among physicians entering our specialty.

To evaluate the incidence and possible predictors associated with port-site metastases following robotic surgery. Prospective study. University Hospital. Women with gynecological cancer. The occurrence of port-site metastases in the first 475 women undergoing robotic surgery for gynecological cancer was reviewed. Rate of port-site metastases. A port-site metastasis was detected in nine of 475 women (1.9%). Eight women had either an unexpected locally advanced disease or lymph-node metastases at the time of surgery. All nine women received postoperative adjuvant therapy. Women with ≥ stage III endometrial cancer and women with node positive cervical cancer had a significantly higher risk of developing a port-site metastasis, as did women with high-risk histology endometrial cancer. Port-site metastases were four times more likely to occur in a specimen-retrieval port. One (0.2%) isolated port-site metastasis was detected. The median time to occurrence of a port-site metastasis was 6 months (range 2-19 months). Six of the nine women (67%) have died and their median time of survival from recurrence was 4 months (range 2-16 months). In women with gynecological cancer, the incidence of port-site metastases following robotic surgery was 1.9%. High-risk histology and/or advanced stage of disease at surgery seem to be contributing factors. © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

[Lysenkoism in Polish botany].

Science.gov (United States)

Köhler, Piotr

2008-01-01

Lysenkoism in Poland was never an autonomous phenomenon. The whole array of reasons for which it appeared in Polish science would require a separate study--here it only needs to be pointed out that the major reasons included terror on the part of the security service, lawlessness, the ubiquitous atmosphere of intimidation and terror, censorship, the diminishing sphere of civil liberties, political show trials, propaganda and denunciations. An important role in facilitating the introduction of Lysenkoism was played also by the reorganization of science after World War Two, the isolation of Polish science from science in the West, as well as the damage it had suffered during the war. At first, Lysenkoism was promoted in Poland by a small group of enthusiastic and uncritical proponents. A overview of the events connected with the ten years of Lysenkoism in Poland (end of 1948--beginning of 1958) shows a two-tier picture of how the 'idea' was propagated. The first tier consisted in the activities of the Association of Marxist Naturalists [Koło Przyrodników-Marksistów], which it engaged in since the end of 1948. The Association was later transformed into a Union of Marxist Naturalists, and this in turn merged, in 1952, with the Copernican Society of Polish Naturalists [Polskie Towarzystwo Przyrodników im. Kopernika]. It was that society which promoted Lysenkoism longest, until the end of 1956. The propaganda and training activities of the circle and the society prepared ground for analogous activities of the newly formed Polish Academy of Science (PAN), which--since its very establishment in 1952--engaged in promoting Lysenkoism through its Second Division. These activities were aimed at naturalists, initially at those who were prominent scientists (eg. the conference at Kuźnice, 1950/1951), and then at those who were only starting their academic career (including national courses in new biology at Dziwnów, 1952, or Kortowo, 1953 and 1955).

Obstetric and gynecologic imaging has undergone marked changes in the past 10 years, primarily because of the influence of new imaging modalities. The single modality that has most significantly changed the diagnostic approach to obstetric and gynecologic problems is diagnostic ultrasound. The remarkable ability of this technique to display the anatomy of the gravid and nongravid female pelvis without the use of ionizing radiation motivated the development of techniques and instrumentation that have supplanted but not totally replaced many x-ray based examinations. The use of diagnostic ultrasound for the evaluation of obstetric and gynecologic problems is the dominant theme of this chapter. Areas of patient diagnosis and management in which additional imaging techniques, x-rays, or magnetic resonance are used are presented where appropriate

Poland is among the countries which reported the highest rates of mortality from cancer. The health behaviours of people are influenced, among other things, by their beliefs about cancer, but their evaluation of oncological institutions and specialists seems also to be of great importance. Objectives. 1. How the respondents evaluate Polish oncology: a) the conditions of treatment in oncology hospitals, b) access to oncological medical services, c) the competence of oncologists. 2. What are the socio-cultural factors of the assessment of Polish oncology? 3. What is the influence of the grade level of the assessment of Polish oncology on the degree of fear and the knowledge about cancer? The study was carried out with a sample of 910 adult residents of Wroclaw in south-west Poland. Quota sampling was used. An interview questionnaire was used as the method. Analysis of the data showed a negative image of Polish oncology, according to the study participants: dissatisfaction with both treatment conditions and with access to medical services. Assessment of Polish oncology depends primarily on education, age and economic situation, as well as 'family history of cancer', and attitude towards doctors. The lower the rating of Polish oncology, the lower the medical knowledge, and the higher the level of fear of cancer. Negative assessment of Polish oncology perpetuates the fear of cancer in society. There is a need for constant improvement of the quality of medical oncology services, for building public trust in physicians, to fight inequalities in health, and to take into account the lay perspectives in developing strategies to combat cancer.

2017-05-01

The aim of this study was to understand the current situation of surgical education and training in Europe among members of the European Society of Gynecological Oncology (ESGO) and its impact on the daily surgical practice of those that have completed an accredited fellowship in gynecologic oncology. A questionnaire addressing topics of interest in surgical training was designed and sent to ESGO members with surgical experience in gynecologic oncology. The survey was completely confidentially and could be completed in less than 5 minutes. Responses from 349 members from 42 European countries were obtained, which was 38% of the potential target population. The respondents were divided into 2 groups depending on whether they had undergone an official accreditation process. Two thirds of respondents said they had received a good surgical education. However, accredited gynecologists felt that global surgical training was significantly better. Surgical self-confidence among accredited specialists was significantly higher regarding most surgical oncological procedures than it was among their peers without such accreditation. However, the rate of self-assurance in ultraradical operations, and bowel and urinary reconstruction was quite low in both groups. There was a general request for standardizing surgical education across the ESGO area. Respondents demanded further training in laparoscopy, ultraradical procedures, bowel and urinary reconstruction, and postoperative management of complications. Furthermore, they requested the creation of fellowship programs in places where they are not now accredited and the promotion of rotations and exchange in centers of excellence. Finally, respondents want supporting training in disadvantaged countries of the ESGO area. Specialists in gynecologic oncology that have obtained a formal accreditation received a significantly better surgical education than those that have not. The ESGO responders recognize that their society should

The mortality pattern among 86 men was determined to investigate the possible hazards of polishing steel. The men had polished steel with polishing paste for at least five years. The polishing pastes had contained tallow, beeswax, carnauba wax, alundum, carborundum, ferric oxide, and chalk. A total of 18 men had died compared with 13.3 expected. Four had died of stomach cancer compared with 0.44 expected (p less than 0.005). The mortality for other causes of death was not increased. The study does not permit any definite conclusion but indicates a possible cancer hazard among polishers. PMID:7066237

Full Text Available Introduction. LeFort colpocleisis (LFC is a safe and effective obliterative surgical option for older women with advanced pelvic organ prolapse who no longer desire coital activity. A major disadvantage is the limited ability to evaluate for post-LFC gynecologic malignancies. Methods. We present the first case of endometrioid ovarian cancer diagnosed after LFC and review all reported gynecologic malignancies post-LFC in the English medical literature. Results. This is the second reported ovarian cancer post-LFC and the first of the endometrioid subtype. A total of nine other gynecologic malignancies post-LFC have been reported in the English medical literature. Conclusions. Gynecologic malignancies post-LFC are rare.

The Helios and Antares CO 2 fusion laser systems incorporate numerous large sodium chloride windows. These must be refinished periodically, making necessary a consistent and predictable polishing capability. A continuous polisher (or annular lap) which might at Kirtland's Developmental Optical Facility. Large NaCl windows had not been polished on this type of machine. The machine has proven itself capable of producing lambda/16 figures at 633 nm (HeNe) with extremely smooth surfaces on glass. Since then, we have been working exclusively on NaCl optics. Due to different polishing parameters between NaCl and glass, and the slight solubility of the pitch in the slurry, this phase presents new problems. The work on glass will be reviewed. Results on NaCl to date will be reported. The potential of this type of machine relative to prisms, thin and irregularly shaped optics will be discussed

To determine the effectiveness of a new pediatric and adolescent gynecology (PAG) curriculum for improving obstetrics/gynecology resident physician knowledge and comfort level in patient management and to describe the current deficiencies in resident physician knowledge and comfort level in PAG. A PAG curriculum was implemented for the obstetrics/gynecology resident physicians (n = 20) at the University of South Florida in July 2013. Before and after the curriculum was introduced, resident physicians and recent graduates of the residency program completed a survey to assess their comfort level and a knowledge assessment consisting of 20 case-based questions. University-based residency program. Resident physicians and recent resident physician graduates in the Department of Obstetrics and Gynecology. Introduction of a PAG curriculum during the 2013-2014 academic year. Improvement in resident physicians' comfort level and knowledge in PAG. After the curriculum was introduced, comfort increased in examining the genitals of a pediatric gynecology patient (median difference = 1.5; P = .003) and history-taking, physical examination skills, and management (median difference = 1; P = .002) compared with before the curriculum. There was no significant difference in overall quiz score (15.5 ± 1.87 vs 15.8 ± 1.3; P = .78). A curriculum in PAG did improve resident comfort level in managing PAG patients, but did not significantly improve knowledge of this topic. Copyright © 2016.

In the past few decades, there has been an overwhelming increase in childhood and adolescent obesity worldwide. Besides the well recognized cardiometabolic complications and other physical conditions associated with obesity, during adolescence, it causes psychological and social distress in a period of life that is already sensitive for a girl. This in turn increases their risk of low self-esteem and depression. Furthermore, obesity diminishes health-related quality of life and years of life. Overweight and obese teenagers are more likely to have gynecologic and obstetric complications, during adolescence and also later in life. Consequences of obese and overweight childhood and adolescence include sexual maturation and reproductive dysfunction, alterations in menstruation, dysmenorrhea, risky sexual behavior, and inefficient use of contraception, polycystic ovary syndrome, bone density abnormalities, macromastia, and an increased risk of breast and endometrial cancer. Obese adolescents are at greater risk of pregnancy and perinatal complications, such as preeclampsia, gestational hypertension and preeclampsia, gestational diabetes mellitus, primary cesarean delivery, and induction of labor, to mention a few. Evidence shows that infants born to obese teenagers are also more likely to have complications including preterm or post-term delivery, small-for-gestational age newborns, macrosomia, meconium aspiration, respiratory distress, and even stillbirth, among others. This comprehensive review focuses on the gynecological and obstetric consequences of obesity in adolescent girls. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

Full Text Available Guidelines for screening of cervical cancer and pelvic exams for older women have recently changed. These changes may have unexpected sequelae in women over 65 years of age. This manuscript provides a review of gynecologic screening recommendations for older women in the U.S. and potential ramifications of these recent changes. Peer reviewed guidelines from the American College of Obstetrics and Gynecology, U.S. Preventative Task Force Services, the American Cancer Society, The Centers for Disease Control, and multiple original research articles and reviews were reviewed for this manuscript. Women over 65 are at greatest risk to develop late stage diagnoses of cancers, pelvic organ disease, incontinence, and infections. Clinicians will need to acutely consider this fact when communicating and screening this population. We conclude that practitioners should be aware of the new guidelines and should consider including gynecologic health history and symptom analysis as part of annual exams in women of all ages.

Convergent Polishing: A Simple, Rapid, Full Aperture Polishing Process of High Quality Optical Flats & Spheres

Convergent Polishing is a novel polishing system and method for finishing flat and spherical glass optics in which a workpiece, independent of its initial shape (i.e., surface figure), will converge to final surface figure with excellent surface quality under a fixed, unchanging set of polishing parameters in a single polishing iteration. In contrast, conventional full aperture polishing methods require multiple, often long, iterative cycles involving polishing, metrology and process changes to achieve the desired surface figure. The Convergent Polishing process is based on the concept of workpiece-lap height mismatch resulting in pressure differential that decreases with removal and results in the workpiece converging to the shape of the lap. The successful implementation of the Convergent Polishing process is a result of the combination of a number of technologies to remove all sources of non-uniform spatial material removal (except for workpiece-lap mismatch) for surface figure convergence and to reduce the number of rogue particles in the system for low scratch densities and low roughness. The Convergent Polishing process has been demonstrated for the fabrication of both flats and spheres of various shapes, sizes, and aspect ratios on various glass materials. The practical impact is that high quality optical components can be fabricated more rapidly, more repeatedly, with less metrology, and with less labor, resulting in lower unit costs. In this study, the Convergent Polishing protocol is specifically described for fabricating 26.5 cm square fused silica flats from a fine ground surface to a polished ~λ/2 surface figure after polishing 4 hr per surface on a 81 cm diameter polisher.

Gynecologic malignancies are the third most common cancer among women in the United States. Because of often subtle early findings, the diagnosis may not be made before the widespread dissemination of the disease. The Emergency Department physician will commonly encounter a woman with vaginal bleeding, pelvic pain, or a symptomatic abdominal mass. In this article, we have described the epidemiology, recognized patterns of spread, and associated findings of gynecologic tumors. The proper Emergency Department evaluation and management of these problems is emphasized with guidelines for the timing of referrals and consultation with the gynecologic oncologist. The treatment of gynecologic malignancies is often complicated and responsible for Emergency Department visits. The various modalities are addressed according to the organ systems affected and include sections on postoperative problems, gastrointestinal complaints, urologic complications of therapy, radiation therapy and its complications, with an emphasis on the most serious complications necessitating either careful outpatient management or hospital admission. As cost-containment pressure grows, we have included sections on chemotherapy and total parenteral nutrition, both of which are becoming common outpatient events for the cancer patient. 28 references

The Japan Society of Obstetrics and Gynecology implemented a registry report system for the clinical practice of assisted reproductive technology in 1986. The aggregated results from 1992 to 2014 are reported herein. The total number of registered treatments was 393 745 cycles, of which 66 550 were pregnancy cycles and 46 008 were cycles with a live birth. Compared to the number of registered treatments in 2008, when the cycle-based registry was newly introduced, there was a 2.07-fold increase in the total number of treatments and a 2.25-fold increase in the number of cycles with a live birth. As the average age of patients who receive assisted reproductive technology has become markedly higher year by year, the most common age of those patients who received assisted reproductive technology in 2014 was 40 years. The total numbers of both assisted reproductive technology treatments and assisted reproductive technology live births are likely to be higher in the future. In addition, the trend toward aging patients seems to be continuing into the future.

2014-01-01

The Society of Gynecologic Surgeons Systematic Review Group performed a systematic review of both randomized and observational studies to compare robotic vs nonrobotic surgical approaches (laparoscopic, abdominal, and vaginal) for treatment of both benign and malignant gynecologic indications to compare surgical and patient-centered outcomes, costs, and adverse events associated with the various surgical approaches. MEDLINE and the Cochrane Central Register of Controlled Trials were searched from inception to May 15, 2012, for English-language studies with terms related to robotic surgery and gynecology. Studies of any design that included at least 30 women who had undergone robotic-assisted laparoscopic gynecologic surgery were included for review. The literature yielded 1213 citations, of which 97 full-text articles were reviewed. Forty-four studies (30 comparative and 14 noncomparative) met eligibility criteria. Study data were extracted into structured electronic forms and reconciled by a second, independent reviewer. Our analysis revealed that, compared with open surgery, robotic surgery consistently confers shorter hospital stay. The proficiency plateau seems to be lower for robotic surgery than for conventional laparoscopy. Of the various gynecologic applications, there seems to be evidence that renders robotic techniques advantageous over traditional open surgery for management of endometrial cancer. However, insofar as superiority, conflicting data are obtained when comparing robotics vs laparoscopic techniques. Therefore, the specific method of minimally invasive surgery, whether conventional laparoscopy or robotic surgery, should be tailored to patient selection, surgeon ability, and equipment availability.

Objective To describe the prevalence of musculoskeletal pain and symptoms in gynecologic surgeons. Design Prospective cross-sectional survey study (Canadian Task Force classification II-2). Setting Virtual. All study participants were contacted and participated via electronic means. Participants Gynecologic surgeons. Interventions An anonymous, web-based survey was distributed to gynecologic surgeons via electronic newsletters and direct E-mail. Measurements and Main Results There were 495 respondents with complete data. When respondents were queried about their musculoskeletal symptoms in the past 12 months, they reported a high prevalence of lower back (75.6%) and neck (72.9%) pain and a slightly lower prevalence of shoulder (66.6%), upper back (61.6%), and wrist/hand (60.9%) pain. Many respondents believed that performing surgery caused or worsened the pain, ranging from 76.3% to 82.7% in these five anatomic regions. Women are at an approximately twofold risk of pain, with adjusted odds ratios (OR) of 1.88 (95% confidence interval [CI], 1.1–3.2; p 5 .02) in the lower back region, OR 2.6 (95% CI, 1.4–4.8; p 5 .002) in the upper back, and OR 2.9 (95% CI, 1.8–4.6; p 5 .001) in the wrist/hand region. Conclusion Musculoskeletal symptoms are highly prevalent among gynecologic surgeons. Female sex is associated with approximately twofold risk of reported pain in commonly assessed anatomic regions.

Kirillin, Mikhail; Motovilova, Tatiana; Shakhova, Natalia

2017-12-01

Modern gynecologic practice requires noninvasive diagnostics techniques capable of detecting morphological and functional alterations in tissues of female reproductive organs. Optical coherence tomography (OCT) is a promising tool for providing imaging of biotissues with high resolution at depths up to 2 mm. Design of the customized probes provides wide opportunities for OCT use in gynecology. This paper contains a retrospective insight into the history of OCT employment in gynecology, an overview of the existing gynecologic OCT probes, including those for combination with other diagnostic modalities, and state-of-the-art application of OCT for diagnostics of tumor and nontumor pathologies of female genitalia. Perspectives of OCT both in diagnostics and treatment planning and monitoring in gynecology are overviewed.

The application of robotics is an innovation in the field of gynecologic surgery. Our objective was to evaluate the currently available literature on the cost assessment of robotic surgery of various operations in the field of gynecologic surgery. PubMed and Scopus databases were systematically searched in order to retrieve the included studies in our review. We retrieved 23 studies on a variety of gynecologic operations. The mean cost for robotic, open and laparoscopic surgery ranged from 1731 to 48,769, 894 to 20,277 and 411 to 41,836 Euros, respectively. Operative charges, in hysterectomy, for robotic, open and laparoscopic technique ranged from 936 to 33,920, 684 to 25,616 and 858 to 25,578 Euros, respectively. In sacrocolpopexy, these costs ranged from 2067 to 7275, 2904 to 69,792 and 1482 to 2000 Euros, respectively. Non-operative charges ranged from 467 to 39,121 Euros. The mean total costs for myomectomy ranged from 27,342 to 42,497 and 13,709 to 20,277 Euros, respectively, for the robotic and open methods, while the mean total cost of the laparoscopic technique was 26,181 Euros. Conversions to laparotomy were present in 79/36,185 (0.2%) cases of laparoscopic surgery and in 21/3345 (0.62%) cases of robotic technique. Duration of robotic, open and laparoscopic surgery ranged from 50 to 445, 83.7 to 701 and 74 to 330 min, respectively. Robotic surgery has the potential to become cost-effective in centers with many patients while industry competition could reduce the cost of the robotic instrumentation, making robotic technology more affordable and cost-effective. © 2014 The Authors.

In Poland in 2007, according to the National Cancer Registry 3431 women were diagnosed with cervical cancer and 1907 died. To change the unfavorable epidemiologic situation, in 2005 the Ministry of Health (MH), the National Health Fund (NHF) and the Polish Gynecological Society following WHO/IARC guidelines developed a National Population-Based Cervical Cancer Screening Program. Its implementation and roll-out started in 2006. The target population are women aged 25 to 59 insured in the National Health Fund. A Pap test is done with a three-year interval, free of charge. The system is based on personal invitations sent by regular post. Invitation to screening is supported by a social educational campaign "Choose Life" run under one slogan and logo across the whole country The NHF data base enables identification of women to screen. Pap smears are collected by gynecologists and since 2008 also by midwives trained and certified by the Program National Coordinating Center Pap test results are reported in the Bethesda 2001 system. The Screening Program has its system of quality assurance and control and is supported by a specially designed computer data base called SIMP (System of Information Monitoring in Prophylaxis) with online access to all records. In addition to organized, population-based screening there is also opportunistic screening in Poland practiced either by private gynecological practices or by some units that cooperate with the National Health Fund, but do Pap tests as an element of comprehensive gynecological examination. Those smears are not registered in the SIMP. Our aim was analysis of attendance rate in the Cervical Cancer Screening Program in the years 2007-2009. We also investigated correlation between screening coverage and invitation sending schedule, as well as between coverage and screening accessibility determined by the number of gynaecological practices where Pap smears are collected. Attendance rate in the Screening Program was evaluated

Robotic assisted surgery is not yet widely applied in the pediatric field. We report our initial experience regarding the feasibility, safety, benefits, and limitations of robot-assisted surgery in pediatric gynecological patients. Descriptive, retrospective report of experience with pediatric gynecological patients over a period of 12 months. Department of Pediatric Surgery, IRCCS Policlinico San Matteo Foundation. Children and adolescents, with a surgical diagnosis of ovarian and/or tubal lesions. Robot assembly time and operative time, days of hospitalization, time to cessation of pain medication, complication rate, conversion rate to laparoscopic procedure and trocar insertion strategy. Six children and adolescents (2.4-15 yrs), weighing 12-55 kg, underwent robotic assisted surgery for adnexal pathologies: 2 for ovarian cystectomy, 2 for oophorectomy, 1 for right oophorectomy and left salpingo-oophorectomy for gonadal disgenesis, 1 for exploration for suspected pelvic malformation. Mean operative time was 117.5 ± 34.9 minutes. Conversion to laparatomy was not necessary in any of the cases. No intra- or postoperative complications occurred. Initial results indicate that robotic assisted surgery is safely applicable in the pediatric gynecological population, although it is still premature to conclude that it provides better clinical outcomes than traditional laparoscopic surgery. Randomized, prospective, comparative studies will help characterize the advantages and disadvantages of this new technology in pediatric patients.

Pelvic artery embolization in gynecological bleeding

International Nuclear Information System (INIS)

Hausegger, K.A.; Schreyer, H.; Bodhal, H.

2002-01-01

The most common reasons for gynecological bleeding are pregnancy-related disorders, fibroids of the uterus, and gynecological malignances. Transarterial embolization is an effective treatment modality for gynecological bleeding regardless of its etiology. Depending on the underlying disease, a different technique of embolization is applied. In postpartal bleeding a temporary effect of embolization is desired, therefore gelatine sponge is used as embolizing agent. In fibroids and malignant tumors the effect should permanent, therefore PVA particles are used. Regardless the etiology, the technical and clinical success of transarterial embolization is at least 90%. In nearly every patient a post-embolization syndrome can be observed, represented by local pain and fever. This post-embolization syndrome usually does not last longer than 3 days. If embolization is performed with meticulous attention to angiographic technique and handling of embolic material, ischemic damage of adjacent organs is rarely observed. Transarterial embolization should be an integrative modality in the treatment of gynecological bleeding. (orig.) [de

In 2016, 13 topics were selected as major research advances in gynecologic oncology. For ovarian cancer, study results supporting previous ones regarding surgical preventive strategies were reported. There were several targeted agents that showed comparable responses in phase III trials, including niraparib, cediranib, and nintedanib. On the contrary to our expectations, dose-dense weekly chemotherapy regimen failed to prove superior survival outcomes compared with conventional triweekly regimen. Single-agent non-platinum treatment to prolong platinum-free-interval in patients with recurrent, partially platinum-sensitive ovarian cancer did not improve and even worsened overall survival (OS). For cervical cancer, we reviewed robust evidences of larger-scaled population-based study and cost-effectiveness of nonavalent vaccine for expanding human papillomavirus (HPV) vaccine coverage. Standard of care treatment of locally advanced cervical cancer (LACC) was briefly reviewed. For uterine corpus cancer, new findings about appropriate surgical wait time from diagnosis to surgery were reported. Advantages of minimally invasive surgery over conventional laparotomy were reconfirmed. There were 5 new gene regions that increase the risk of developing endometrial cancer. Regarding radiation therapy, Post-Operative Radiation Therapy in Endometrial Cancer (PORTEC)-3 quality of life (QOL) data were released and higher local control rate of image-guided adaptive brachytherapy was reported in LACC. In addition, 4 general oncology topics followed: chemotherapy at the end-of-life, immunotherapy with reengineering T-cells, actualization of precision medicine, and artificial intelligence (AI) to make personalized cancer therapy real. For breast cancer, adaptively randomized trials, extending aromatase inhibitor therapy, and ribociclib and palbociclib were introduced. Copyright © 2017.

Venous thromboembolism (VTE) is the leading cause of mortality and morbidity in women following gynecologic surgery. To determine the efficacy of a second-generation low molecular weight heparin (bemiparin) for thromboprophylaxis after benign gynecologic surgery. We performed a single-blind randomized controlled trial including women in the moderate-risk, high-risk and highest-risk groups for developing VTE after benign gynecologic surgery. Participants were randomized at a 1 : 1 ratio into parallel groups to receive either seven daily doses of 3500 IU of subcutaneous bemiparin or to a non-intervention group receiving standard rehydration and advice on ambulation. Participants were followed up for 7 days and 30 days postoperatively for symptomatic VTE, which was confirmed by compression Doppler ultrasound, magnetic resonance imaging, or computed tomographic pulmonary angiography, according to the type of VTE. In total, 387 participants were randomized to the bemiparin group and 387 to the non-intervention group. The incidence of symptomatic VTE (deep vein thrombosis and pulmonary embolism) events was lower (0/377) in participants who received bemiparin than in those who received no pharmacologic intervention (12/380, 3.2%; 95% confidence interval [CI] 0.002-0.6). Logistic regression analysis showed significant associations between VTE and immobility (odds ratio [OR] 7.1; 95% CI 1.3-36.2), varicose veins (OR 16.8; 95% CI 3.1-76.2), and thrombophilia (OR 39.3; 95% CI 1.5-1006.7). There were no major bleeding events or side effects related to the use of bemiparin. Bemiparin was an effective thromboprophylactic agent for preventing venous thrombosis after benign gynecologic surgery. © 2015 International Society on Thrombosis and Haemostasis.

Polish-German bilingualism at school. A Polish perspective

Directory of Open Access Journals (Sweden)

Pulaczewska, Hanna

2014-03-01

Full Text Available This article presents the institutional frames for the acquisition of Polish literacy skills in Germany and the maintenance of Polish-German bilingualism after the repatriation of bilingual children to Poland. These processes are examined in the context of recent developments in the European domestic job market. While the European Union has placed proficiency in several languages among its educational objectives, and foreign languages have been made obligatory school subjects in all member countries, the potential advantages of internal European migrations for producing high-proficiency bilinguals are being ignored. Bilingualism resulting from migration and biculturalism enjoys little social prestige in the host countries. In Germany, there is significant regional variation in how school authorities react to challenges posed by the presence of minority languages. In many cases, the linguistic potential of many second-generation migrants and re-emigrants gets largely wasted because of lacking interest and incentives from German and Polish institutions alike.

The gynecologic oncology fellowship interview process: Challenges and potential areas for improvement

Full Text Available The application and interview process for gynecologic oncology fellowship is highly competitive, time-consuming and expensive for applicants. We conducted a survey of successfully matched gynecologic oncology fellowship applicants to assess problems associated with the interview process and identify areas for improvement. All Society of Gynecologic Oncology (SGO list-serve members who have participated in the match program for gynecologic oncology fellowship were asked to complete an online survey regarding the interview process. Linear regression modeling was used to examine association between year of match, number of programs applied to, cost incurred, and overall satisfaction. Two hundred and sixty-nine eligible participants reported applying to a mean of 20 programs [range 1–45] and were offered a mean of 14 interviews [range 1–43].

Lower limb lymphedema (LLL) is one of the most frequent postoperative complications of retroperitoneal lymphadenectomy for gynecologic cancer. LLL often impairs quality of life, activities of daily living, sleep, and sex in patients with gynecologic cancer. We conducted this study to evaluate the incidence and risk factors for LLL after gynecologic cancer surgery in patients who received assessment and periodic complex decongestive physiotherapy (CDP). We retrospectively reviewed 126 cases of gynecologic cancer that underwent surgery involving retroperitoneal lymphadenectomy at Tottori University Hospital between 2009 and 2012. All patients received physical examinations to detect LLL and underwent CDP by nurse specialists within several months after surgery. The International Society of Lymphology staging of lymphedema severity was used as the diagnostic criteria. Of 126 patients, 57 (45.2%) had LLL, comprising 45 and 12 patients with stage 1 and stage 2 LLL, respectively. No patient had stage 3 LLL. LLL was present in 37 (29.4%) patients at the initial physical examination. Multivariate analysis revealed that adjuvant concurrent chemoradiotherapy and age ≥ 55 years were independent risk factors for ≥ stage 2 LLL. To minimize the incidence of ≥ stage 2 LLL, gynecologic oncologists should be vigilant for this condition in patients who are ≥ 55 years and in those who undergo adjuvant chemoradiotherapy. Patients should be advised to have a physical assessment for LLL and to receive education about CDP immediately after surgery involving retroperitoneal lymphadenectomy for gynecologic cancer.

Effect of Music Therapy on Postoperative Pain Management in Gynecological Patients: A Literature Review.

Science.gov (United States)

Sin, Wai Man; Chow, Ka Ming

2015-12-01

Unrelieved postoperative pain may have a negative impact on the physiological and psychological well-being of patients. Pharmacological methods are currently used to relieve such pain in gynecological patients; however, inadequate pain control is still reported, and the use of nonpharmacological pain-relieving methods is increasingly being advocated, one of which is music therapy. The purpose of this literature review was to identify, summarize, and critically appraise current evidence on music therapy and postoperative pain management among gynecological patients. A systematic search of MEDLINE, CINAHL, PsycINFO, British Nursing Index, and Allied and Complementary Medicine was conducted using the search terms music, gynecological, pain, surgery, operative, and post-operative to identify relevant articles in English from 1995 to the present. All identified articles were assessed independently for inclusion into review. A total of 7 articles were included after removal of duplicates and exclusion of irrelevant studies. All the included studies assessed the effects of music therapy on postoperative pain intensity, and three of them measured pain-related physiological symptoms. The findings indicated that music therapy, in general, was effective in reducing pain intensity, fatigue, anxiety, and analgesic consumption in gynecological patients during the postoperative period. It is recommended as an adjunct to pharmacological pain-relieving methods in reducing postoperative pain. Future researches on music therapy to identify the most effective application and evaluate its effect by qualitative study are recommended.

To investigate sexual self-concept, sexual relationships, and sexual functioning, and the relationship between these and certain demographic variables of Irish women, following a diagnosis of gynecologic cancer. Descriptive, correlational. Outpatient gynecologic oncology clinic in a large university hospital in Southern Ireland. 106 women with a diagnosis of and treatment for various gynecologic cancers (cervical, ovarian, endometrial, and vulvar). The Body Image Scale, Sexual Esteem Scale, and Sexual Self-Schema Scale were administered to women a minimum of six weeks postdiagnosis of any form of gynecologic cancer to measure sexual self-concept; the Intimate Relationships Scale to measure sexual relationships; and the Arizona Sexual Experiences Scale to measure sexual functioning. Sexual self-concept, body image, sexual esteem, sexual self-schema, sexual relationships, and sexual functioning. Participants reported negative changes in relation to their sexual self-concept, sexual relationships, and sexual functioning. Participants reported negative changes in relation to all stages of the sexual response cycle. Gynecologic cancer has the potential to negatively affect a woman's sexual self-concept, sexual relationships, and sexual functioning. Sexuality is a multidimensional construct and must be measured in this way. Healthcare professionals must use a holistic approach when providing information and support to patients with gynecologic cancer. Information must be provided to women on how cancer and its treatment has the potential to affect their sexual self-concept, sexual relationships, and sexual functioning, including information on how to overcome these alterations.

In Poland, during parliamentary debate on Foundations for the 'Polish energy policies up to 2010', the importance of public attitudes toward nuclear power has been recalled repeatedly in the context of the future development of nuclear power in Poland. In the governmental document, accepted by Polish Parliament on 1 January 1996, it has been stated that nuclear power plant construction is not foreseen up to the year 2010; nevertheless it has been assumed that the appraisals of the economic feasibility and of the public acceptance level for such investments will be conducted. Thus, the need for such assessments of public opinions and attitudes toward nuclear power has been recognized and accepted by the highest legislative power organ in Poland

Gynecologic cytopathology is a heavily regulated field, with Clinical Laboratory Improvement Amendments of 1988 mandating the collection of many quality metrics. There is a lack of consensus regarding methods to collect, monitor, and benchmark these data and how these data should be used in a quality assurance program. Furthermore, the introduction of human papilloma virus testing and proficiency testing has provided more data to monitor. To determine good laboratory practices in quality assurance of gynecologic cytopathology. Data were collected through a written survey consisting of 98 questions submitted to 1245 Clinical Laboratory Improvement Amendments-licensed or Department of Defense laboratories. There were 541 usable responses. Additional input was sought through a Web posting of results and questions on the College of American Pathologists Web site. Four senior authors who authored the survey and 28 cytopathologists and cytotechnologists were assigned to 5 working groups to analyze data and present statements on good laboratory practices in gynecologic cytopathology at the College of American Pathologists Gynecologic Cytopathology Quality Consensus Conference. Ninety-eight attendees at the College of American Pathologists Gynecologic Cytopathology Quality Consensus Conference discussed and voted on good laboratory practice statements to obtain consensus. This paper describes the rationale, background, process, and strengths and limitations of a series of papers that summarize good laboratory practice statements in quality assurance in gynecologic cytopathology.

This in vitro study evaluated the effect of polishing with different polishing systems on the surface roughness and gloss of commercial composites. One hundred disk-shaped specimens (10 mm in diameter × 2 mm thick) were made with Filtek P-90, Filtek Z350 XT, Opallis, and Grandio. The specimens were manually finished with #400 sandpaper and polished by a single operator using three multistep systems (Superfix, Diamond Pro, and Sof-lex), one two-step system (Polidores DFL), and one one-step system (Enhance), following the manufacturer's instructions. The average surface roughness (μm) was measured with a surface profilometer (TR 200 Surface Roughness Tester), and gloss was measured using a small-area glossmeter (Novo-Curve, Rhopoint Instrumentation, East Sussex, UK). Data were analyzed by two-way analysis of variance and Tukey's test (α=0.05). Statistically significant differences in surface roughness were identified by varying the polishing systems (pGloss was influenced by the composites (pone-step system, Enhance, produced the lowest gloss for all composites. Surface roughness and gloss were affected by composites and polishing systems. The interaction between both also influenced these surface characteristics, meaning that a single polishing system will not behave similarly for all composites. The multistep systems produced higher gloss, while the one-step system produced the highest surface roughness and the lowest gloss of all.

Work as a cultural and personal value: attitudes towards work in Polish society.

Skarzyńska, Krystyna

2002-01-01

The meaning of work for Poles is analyzed here from 2 perspectives: macrosocial and individual. From the macrosocial perspective work attitudes are explained by 3 factors: traditional Polish Catholicism, cultural patterns (influence of noble class tradition), and experience of "real socialism." From an individual perspective some psychological and demographic predictors of an autonomous (intrinsic) work attitude are empirically tested. The autonomous attitude towards work is understood here as treating work as an important autonomous value versus only an instrumental means for earning money. The data was collected by means of standardized interviews run on a representative random sample of adult working Poles, N = 1340.

Information regarding Indonesia obtained from World Bank Report and Statistical Yearbook of Indonesia 2007, epidemiological data obtained from Histopathological Data of Cancer in Indonesia 2002, Department of Health-Registry Body of Indonesian Specialist of Pathology Association-Indonesian Cancer Society; Various Hospitals in big Cities in Indonesia. Indonesia is an Archipelago with a total area of 1,922,570.00 km(2), the population is 222,192,000 (2006), the fourth world rank. Female is 49.86% with life expectancy 69 years. Gross National Product per Capita is 690.00 USD. Histopathological report in 2002 revealed that cervical cancer, ovarian cancer and uterine cancer were the most frequent cancer among female, which were the first (2,532 cases), the third (829 cases) and the eighth (316 cases) rank respectively. The peak age for cervical, uterine and ovarian cancer was 45-54 years. HPV 16, 18 were found in 82% of invasive cervical. Data from various academic hospitals in 2007 showed that cervical cancer is the most common malignancy followed by ovary, uterus, vulva and vagina. Five-year survival rate of stage I, II, III, IV cervical cancer were 50%, 40%, 20%, and 0% respectively. Overall five-year survival rate of carcinoma of the ovary was 54.8%. If sub-classified by stage, five-year survival rate are 94.3%, 75.0%, 31%, and 11.7% for stage I, II, III, and IV respectively. Five-year disease-free survival rate of endometrial cancer was 71.9%. Indonesia is the biggest Archipelago with a dense population but the income per capita still low (poor country). The most common gynecologic cancer is cervical cancer, followed by ovarian and uterine cancer. These cancers are included in top ten cancers in Indonesia. HPV 16, 18 were the most cause of cervical cancer. The five-year survival rates are comparable with world report.

Simulations have been used by the military, airline industry, and our colleagues in other medical specialties to educate, evaluate, and prepare for rare but life-threatening scenarios. Work hour limits for residents in obstetrics and gynecology and decreased patient availability for teaching of students and residents require us to think creatively and practically on how to optimize their education. Medical simulations may address scenarios in clinical practice that are considered important to know or understand. Simulations can take many forms, including computer programs, models or mannequins, virtual reality data immersion caves, and a combination of formats. The purpose of this commentary is to call attention to a potential role for medical simulation in obstetrics and gynecology. We briefly describe an example of how simulation may be incorporated into obstetric and gynecologic residency training. It is our contention that educators in obstetrics and gynecology should be aware of the potential for simulation in education. We hope this commentary will stimulate interest in the field, lead to validation studies, and improve training in and the practice of obstetrics and gynecology.

Linei Augusta Brolini Dellê Urban

Full Text Available Abstract Objective: To present the current recommendations for breast cancer screening in Brazil, as devised by the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Breast Disease Society, and the Brazilian Federation of Gynecological and Obstetrical Associations. Materials and methods: We analyzed scientific studies available in the Medline and Lilacs databases. In the absence of evidence, the recommendations reflected the consensus of a panel of experts. Recommendations: Annual mammography screening is recommended for women 40-74 years of age. Among women ≥ 75 years of age, annual mammography screening should be reserved for those with an expected survival > 7 years. Complementary ultrasound should be considered for women with dense breasts. Complementary magnetic resonance imaging is recommended for women at high risk. When available, an advanced form of mammography known as tomosynthesis can be considered as a means of screening for breast cancer.

Acute abdominal pain related to the female genital organs is frequently encountered in the emergency department. Gynecological emergencies are diseases of the female reproductive system that are potentially life-threatening and peril the sexual function and fertility. In the diagnostic work-up of acute abdominal pain, a wide variety of differential diagnoses needs to be considered depending on the age of the patient and a concomitant pregnancy. There is significant clinical overlap with gastrointestinal emergencies. Therefore, imaging plays a key role in diagnosing the cause of the pain and the planning of the therapy. The aim of this review is to illustrate the significant role of imaging in frequently encountered gynecologic emergencies.

EMMPRIN in gynecologic cancers: pathologic and therapeutic aspects.

Science.gov (United States)

Liu, Dan-tong

2015-07-01

The highly glycosylated transmembrane protein extracellular matrix metalloproteinase inducer (EMMPRIN) is associated with several pathological conditions, including various types of cancers. In different gynecological malignancies, such as ovarian, cervical, and endometrial cancers, EMMPRIN plays significant roles in cell adhesion modulation, tumor growth, invasion, angiogenesis, and metastasis by inducing the production of various molecules, including matrix metalloproteinases and vascular endothelial growth factor. Because of its high level of expression, EMMPRIN can possibly be used as a diagnostic marker of gynecological cancers. Recent studies have showed that targeting EMMPRIN, especially by RNA interference (RNAi) technology, has promising therapeutic potential in basic research on gynecological cancer treatments, which make a platform for the future clinical success. This review study focused on the association of EMMPRIN in gynecological cancers in the perspectives of pathogenesis, diagnosis, and therapeutics.

Rosanna H. E. Krakowsky

2015-05-01

Full Text Available Cancer is the second leading cause of death in females. According to the American Cancer Society, there are 327,660 new cases in breast and gynecological cancers estimated in 2014, placing emphasis on the need for cancer prevention and new cancer treatment strategies. One important approach to cancer prevention involves phytochemicals, biologically active compounds derived from plants. A variety of studies on the impact of dietary compounds found in cruciferous vegetables, green tea and spices like curry and black pepper have revealed epigenetic changes in female cancers. Thus, an important emerging topic comprises epigenetic changes due to the modulation of noncoding RNA levels. Since it has been shown that noncoding RNAs such as microRNAs and long noncoding RNAs are aberrantly expressed in cancer and furthermore are linked to distinct cancer phenotypes, understanding the effects of dietary compounds and supplements on the epigenetic modulator noncoding RNA is of great interest. This article reviews the current findings on nutrition-induced changes in breast and gynecological cancers at the noncoding RNA level.

Pelvic Surgical Site Infections in Gynecologic Surgery

Directory of Open Access Journals (Sweden)

Mark P. Lachiewicz

2015-01-01

Full Text Available The development of surgical site infection (SSI remains the most common complication of gynecologic surgical procedures and results in significant patient morbidity. Gynecologic procedures pose a unique challenge in that potential pathogenic microorganisms from the skin or vagina and endocervix may migrate to operative sites and can result in vaginal cuff cellulitis, pelvic cellulitis, and pelvic abscesses. Multiple host and surgical risk factors have been identified as risks that increase infectious sequelae after pelvic surgery. This paper will review these risk factors as many are modifiable and care should be taken to address such factors in order to decrease the chance of infection. We will also review the definitions, microbiology, pathogenesis, diagnosis, and management of pelvic SSIs after gynecologic surgery.

Clinical application of positron emission tomography (PET) is rapidly increasing for the detection and staging of cancer at whole-body studies performed with 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG). Although many cancers can be detected by FDG-PET, there has been limited clinical experience with FDG-PET for the detection of gynecological cancers including malignancies in uterus and ovary. FDG-PET can show foci of metastatic disease that may not be apparent at conventional anatomic imaging and can aid in the characterization of indeterminate soft-tissue masses. Most gynecological cancers need to surgical management. FDG-PET can improve the selection of patients for surgical treatment and thereby reduce the morbidity and mortality associated with inappropriate surgery. FDG-PET is also useful for the early detection of recurrence and the monitoring of therapeutic effect. In this review, I discuss the clinical feasibility and imitations of this imaging modality in patients with gynecological cancers

Preparation in the business of medicine is reported to be poor across a number of specialties. No data exist about such preparation in gynecologic oncology training programs. Our objectives were to evaluate current time dedicated to these initiatives, report recent graduate perceptions about personal preparedness, and assess areas where improvements in training can occur. Two separate surveys were created and distributed, one to 183 Society of Gynecologic Oncology candidate members and the other to 48 gynecologic oncology fellowship program directors. Candidate member surveys included questions about perceived preparedness for independent research, teaching, job-hunting, insurance, and billing. Program director surveys assessed current and desired time dedicated to the topics asked concurrently on the candidate survey. Statistical analysis was performed using Chi-squared (or Fisher's exact test if appropriate) and logistic regression. Survey response rates of candidate members and program directors were 28% and 40%, respectively. Candidate members wanted increased training in all measures except retrospective protocol writing. Female candidates wanted more training on writing letters of intent (LOI) ( p  = 0.01) and billing ( p  communication between the two may serve to achieve the educational goals of each.

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

THE SOCIALIST YOUTH UNION (1957–1976 – POLISH COUNTERPART OF KOMSOMOL

Directory of Open Access Journals (Sweden)

Joanna Sadowska

2016-10-01

Full Text Available The political system of the Polish People’s Republic was modelled on the Soviet one. Polish youth organizations had the ambitions of being counterparts of Komsomol: they adopted similar work methods and tried to play a similar role in the country. The obvious differences resulted from the specificity of each country and the differences in the societies. The most deeply rooted in the memory of Poles is the Socialist Youth Union, which, being the most stable, existed for almost 20 years with nearly 1.3 million members in the early 1970s. The Union was closely connected with the Polish United Workers’ Party and it had to accomplish two main kinds of political task: to select and prepare future members of the Party, both ordinary and those in the managerial positions, and to educate the whole young generation. The Party indeed treated the organization as its agency, an office dealing with the affairs of youths. However, non-political activity of the Union (culture, entertainment, tourism, etc. was much more effective and evaluated more positively. Actually, there was much more falsehood in the Union: many members were almost completely passive and the work was often only simulated.

Efficiency as a parameter for assessing the Polish healthcare system

Directory of Open Access Journals (Sweden)

Magdalena Bogdan

2018-04-01

Full Text Available Introduction. Efficacy is defined as one of the most valid parameters of health system evaluation. It should be said that there is no consistent definition of the concept of effectiveness in health care, which would allow for the evaluation and comparison of health systems in the world. One can not point to the best or even near ideal of the health system. However, you can rank individual health systems with respect to the evaluation of individual parameters or groups of parameters. One of the possibilities is to evaluate the effectiveness of the system. Aim of the study. The aim of the article is to define and analyze particular types of system effectiveness in the context of the Polish health system. Description of knowledge. The literature on the subject is divided into operational and dynamic efficiency. Dynamic efficiency is divided into adaptive and innovative. The Polish health system is characterized by high operational efficiency. Operational efficiency determines the intensity of the system. The key factor for improving the health of the Polish society, as a factor of socio-economic development of the country is to improve the dynamic efficiency of the system. Conclusions. Health care in Poland has high operational efficiency while low dynamic efficiency, both adaptive and innovative, which clearly demonstrates the existence of a paradox of the overall effectiveness of the health care system in Poland.

Detection of paint polishing defects

2018-06-01

Surface finish plays a major role on perceived product quality, and is the first thing a potential buyer sees. Today end-of-line repairs of the body of cars and trucks are inevitably to secure required surface quality. Defects that occur in the paint shop, like dust particles, are eliminated by manual sanding/polishing which lead to other types of defects when the last polishing step is not performed correctly or not fully completed. One of those defects is known as ‘polishing roses’ or holograms, which are incredibly hard to detect in artificial light but are clearly visible in sunlight. This paper will present the first tests with a measurement set-up newly developed to measure and analyse polishing roses. The results showed good correlations to human visual evaluations where repaired panels were estimated based on the defects’ intensity, severity and viewing angle.

Tooth polishing: The current status

Full Text Available Healthy teeth and gums make a person feel confident and fit. As people go about their daily routines and with different eating and drinking habits, the tooth enamel turns yellowish or gets stained. Polishing traditionally has been associated with the prophylaxis procedure in most dental practices, which patients know and expect. However, with overzealous use of polishing procedure, there is wearing of the superficial tooth structure. This would lead to more accumulation of local deposits. Also, it takes a long time for the formation of the fluoride-rich layer of the tooth again. Hence, now-a-days, polishing is not advised as a part of routine oral prophylaxis procedure but is done selectively based on the patients′ need. The article here, gives an insight on the different aspects of the polishing process along with the different methods and agents used for the same.

Older women in Appalachia: experiences with gynecological cancer.

Science.gov (United States)

Allen, Katherine R; Roberto, Karen A

2014-12-01

The purpose of this study was to explore how older women in rural Appalachia with gynecological cancer construct and interpret their experience with cancer. Grounded in social constructionist theory, semistructured in-depth interviews were conducted with 20 women, aged 51-82, who had been treated for gynecological cancer. Transcripts were analyzed using the constant comparative method. Although women narrated their experience along a common trajectory from symptoms to diagnosis to treatment, four distinct patterns of posttreatment perceptions were described: (a) positive: women believed they were cancer survivors, (b) cautious: women saw themselves as survivors but not risk free, (c) distanced: women viewed themselves as cured and equated survivor with victim, and (d) resigned: women refused more treatment. All of the women acknowledged an inner strength in how they experienced cancer, requiring a more nuanced framework for understanding how negative and positive feelings coexist with faith in a higher power and the capacity to endure a devastating threat to life and health. The findings expand the concept of survivor identity, suggesting that the women's perception that they had met life's challenges with fortitude and inner strength may have more resonance in later life than the concept of survivorship. Family members and medical and public health professionals need to support older women's individual response to cancer recovery and acknowledge their complicated reactions to a cancer diagnosis and prognosis. © The Author 2013.

Nojomi, Marzieh; Agaee, Saideh; Eslami, Samira

2007-07-01

Violence against women and threat of violence are some of the main barriers to women's empowerment and equal participation in the society. However, they often go unnoticed and undocumented and therefore unresolved. For women, one of every five years of healthy life lost because of injury, disease, or premature death is attributable to violence. The aim of this study was to identify the prevalence of domestic violence in women attending three obstetric and gynecologic clinics in Tehran, and to determine the association between domestic violence and demographic factors. One thousand women, 15-64 years old, attending three obstetric and gynecologic clinics affiliated to Iran University of Medical Sciences in Tehran were invited to participate in a cross-sectional survey with self-administered questionnaire. The association between demographic factors (age, level of education, religious believes, annual income, job, husband's employment status, drug and alcohol abuse, previous custody of husbands) and domestic violence was assessed by questionnaire. Five hundred and ninety out of the 1000 women had experienced at least one form of violence (physical, mental, not sexual) from their husbands, 196 women had experienced some forms of controlling behavior and mental violence, and 361 women had been physically threatened. Low level of education in women, nongovernmental job, previous custody, psychiatric disorders of men, and coercive marriage for women were associated with an increased risk of domestic violence. With the high prevalence of domestic violence, health workers should not ignore the seriousness of domestic violence. Health and social personnel should be appropriately trained before "asking all cases" becomes a policy within health and social services.

Conformal polishing approach: Tool footprint analysis

Directory of Open Access Journals (Sweden)

José A Dieste

2016-02-01

Full Text Available Polishing process is one of the most critical manufacturing processes during a metal part production because it determines the final quality of the product. Free-form surface polishing is a handmade process with lots of rejected parts, scrap generation and time and energy consumption. Two different research lines are being developed: prediction models of the final surface quality parameters and an analysis of the amount of material removed depending on the polishing parameters to predict the tool footprint during the polishing task. This research lays the foundations for a future automatic conformal polishing system. It is based on rotational and translational tool with dry abrasive in the front mounted at the end of a robot. A tool to part concept is used, useful for large or heavy workpieces. Results are applied on different curved parts typically used in tooling industry, aeronautics or automotive. A mathematical model has been developed to predict the amount of material removed in function of polishing parameters. Model has been fitted for different abrasives and raw materials. Results have shown deviations under 20% that implies a reliable and controllable process. Smaller amount of material can be removed in controlled areas of a three-dimensional workpiece.

To investigate the usefulness of soluble galectin-9 (Gal-9) in the noninvasive laboratory diagnosis of endometriosis and various gynecologic disorders. Prospective case-control study. University medical centers. A total of 135 women of reproductive age were involved in the study, 77 endometriosis patients, 28 gynecologic controls, and 30 healthy women. Diagnostic laparoscopy and collection of tissue biopsies, peritoneal cells, and native peripheral blood from different case groups of gynecology patients and healthy women. The expression of mRNA and serum concentration of Gal-9. Semiquantitative reverse transcription-polymerase chain reaction analysis and serum soluble Gal-9 ELISA were performed on three different cohorts of patients: those with endometriosis, those with benign gynecologic disorders, and healthy controls. Differences in the Gal-9 concentrations between the investigated groups and the stability of Gal-9 in the serum and diagnostic characteristics of Gal-9 ELISA were determined by statistical evaluation and receiver operating characteristic (ROC) curve analysis. Significantly elevated Gal-9 levels were found in both minimal-mild (I-II) and moderate-severe (III-IV) stages of endometriosis in comparison with healthy controls. At a cutoff of 132 pg/mL, ROC analysis revealed an excellent diagnostic value of Gal-9 ELISA in endometriosis (area under the curve = 0.973) with a sensitivity of 94% and specificity of 93.75%, indicating better diagnostic potential than that of other endometriosis biomarkers. Furthermore, various pelvic pain or infertility-associated benign gynecologic conditions were also associated with increased serum Gal-9 levels. Our results suggest that Gal-9 could be a promising noninvasive biomarker of endometriosis and a predictor of various infertility or pelvic pain-related gynecologic disorders.

Advantages of robotics in benign gynecologic surgery.

Truong, Mireille; Kim, Jin Hee; Scheib, Stacey; Patzkowsky, Kristin

2016-08-01

The purpose of this article is to review the literature and discuss the advantages of robotics in benign gynecologic surgery. Minimally invasive surgery has become the preferred route over abdominal surgery. The laparoscopic or robotic approach is recommended when vaginal surgery is not feasible. Thus far, robotic gynecologic surgery data have demonstrated feasibility, safety, and equivalent clinical outcomes in comparison with laparoscopy and better clinical outcomes compared with laparotomy. Robotics was developed to overcome challenges of laparoscopy and has led to technological advantages such as improved ergonomics, visualization with three-dimensional capabilities, dexterity and range of motion with instrument articulation, and tremor filtration. To date, applications of robotics in benign gynecology include hysterectomy, myomectomy, endometriosis surgery, sacrocolpopexy, adnexal surgery, tubal reanastomosis, and cerclage. Though further data are needed, robotics may provide additional benefits over other approaches in the obese patient population and in higher complexity cases. Challenges that arose in the earlier adoption stage such as the steep learning curve, costs, and operative times are becoming more optimized with greater experience, with implementation of robotics in high-volume centers and with improved training of surgeons and robotic teams. Robotic laparoendoscopic single-site surgery, albeit still in its infancy where technical advantages compared with laparoscopic single-site surgery are still unclear, may provide a cost-reducing option compared with multiport robotics. The cost may even approach that of laparoscopy while still conferring similar perioperative outcomes. Advances in robotic technology such as the single-site platform and telesurgery, have the potential to revolutionize the field of minimally invasive gynecologic surgery. Higher quality evidence is needed to determine the advantages and disadvantages of robotic surgery in benign

Zerodur polishing process for high surface quality and high efficiency

International Nuclear Information System (INIS)

Tesar, A.; Fuchs, B.

1992-08-01

Zerodur is a glass-ceramic composite importance in applications where temperature instabilities influence optical and mechanical performance, such as in earthbound and spaceborne telescope mirror substrates. Polished Zerodur surfaces of high quality have been required for laser gyro mirrors. Polished surface quality of substrates affects performance of high reflection coatings. Thus, the interest in improving Zerodur polished surface quality has become more general. Beyond eliminating subsurface damage, high quality surfaces are produced by reducing the amount of hydrated material redeposited on the surface during polishing. With the proper control of polishing parameters, such surfaces exhibit roughnesses of < l Angstrom rms. Zerodur polishing was studied to recommend a high surface quality polishing process which could be easily adapted to standard planetary continuous polishing machines and spindles. This summary contains information on a polishing process developed at LLNL which reproducibly provides high quality polished Zerodur surfaces at very high polishing efficiencies

Lysenko affair and Polish botany.

Science.gov (United States)

Köhler, Piotr

2011-01-01

This article describes the slight impact of Lysenkoism upon Polish botany. I begin with an account of the development of plant genetics in Poland, as well as the attitude of scientists and the Polish intelligentsia toward Marxist philosophy prior to the World War II. Next I provide a short history of the introduction and demise of Lysenkoism in Polish science, with a focus on events in botany, in context with key events in Polish science from 1939 to 1958. The article outlines the little effects of Lysenkoism upon botanists and their research, as well as how botanists for the most part rejected what was often termed the "new biology." My paper shows that though Lysenko's theories received political support, and were actively promoted by a small circle of scientists and Communist party activists, they were never accepted by most botanists. Once the political climate in Poland altered after the events of 1956, Lysenko's theories were immediately abandoned.

Diagnostic imaging in the staging of gynecologic cancers

International Nuclear Information System (INIS)

Forstner, R.; Graf, A.

1999-01-01

The prognosis in patients with gynecologic cancers depends not only on the stage but also on a wide spectrum of other findings. Cross-sectional imaging modalities, including sonography, CT and MRI, have increasingly been used for optimal treatment planning in gynecologic cancers. Their staging criteria are based on the well-established FIGO staging system. CT and MRI compete with sonography, which plays a pivotal role in the valuation of the female pelvis. This paper reviews the role of sonography, CT and MRI in the staging of gynecologic malignancies. It puts the emphasis on MRI, which has been established as imaging modality of choice in the preoperative evaluation of cervical and endometrial cancer, and which seems slightly superior to CT in the staging of ovarian cancer.

Thorvinger, B.

1990-05-01

The role and clinical value of the modern radiologic methods for evaluation of gynecologic tumors is not finally settled. The aims of our investigation were therefore to compare clinical examination with CT in patients with possible recurrence of cervical carcinoma; to evaluate the usefulness of CT in patients with fistulas following gynecologic tumors or their treatment; to evaluate the ability of transabdominal US and MR imaging in intrauterine staging including myometrial invasion on patients with endometrial carcinoma; to evaluate CT in the capacity of monitoring therapy response, probable recurrence or clinical remission in patients with ovarian carcinoma; and to evaluate the effect of intraarterial occlusion in facilitating surgery and in evaluating the role of the intraarterial infusion in gynecologic tumors otherwise refractory to all therapy given. CT was more accurate (91%) than clinical pelvic examination (78%) in revealing extensive disease after radiation and/ or surgical treatment. CT was also a most valuable tool in demonstrating genital fistulas following gynecologic malignancy or its treatment. Transabdominal US did not improve staging in early endometrila carcinoma while MR had potential for delineating intrauterine tumor growth (accuracy for myometrial invasion 95%). CT was most valuable in the evaluation of therapeutic response of ovarian malignancy. For possible recurrence or in clinical remission, only positive CT was of clinical significance. The potentials of transcatheter intraarterial management in order to facilitate operability are also discussed. (92 refs.)

Pelvic floor disorders in gynecological malignancies. An overlooked problem?

Directory of Open Access Journals (Sweden)

Oana M. Bodean

2018-04-01

Full Text Available Cervical, endometrial, ovarian, vulvar, and vaginal cancers affect women of a broad age spectrum. Many of these women are still sexually active when their cancer is diagnosed. Treatment options for gynecological malignancies, such as gynecological surgery, radiation, and chemotherapy, are proven risk factors for pelvic floor dysfunction. The prevalence of urinary incontinence, fecal incontinence, and sexual dysfunction before cancer treatment is still unclear. Hypotheses have been raised in the literature that these manifestations could represent early symptoms of pelvic cancers, but most remain overlooked even in cancer surviving patients. The primary focus of therapy is always cancer eradication, but as oncological and surgical treatment options become more successful, the number of cancer survivors increases. The quality of life of patients with gynecological cancers often remains an underrated subject. Pelvic floor disorders are not consistently reported by patients and are frequently overlooked by many clinicians. In this brief review we discuss the importance of pelvic floor dysfunction in patients with gynecological malignant tumors.

Chemical polishing of partially oxidized T-111 alloy

International Nuclear Information System (INIS)

Teaney, P.E.

1974-01-01

The specimens were pressure-mounted in Bakelite and ground through 600 grit on silicon carbide papers. The specimens were rough-polished on a vibratory polisher for 4 to 6 h, using a water slurry of one micron alumina on Texmet, followed by 0.3-μ alumina on Texmet overnight. Final polishing was accomplished by continuous swabbing with a chemical polish. A chemical polish consisting of ten parts lactic acid, four parts nitric acid, and four parts hydrofluoric acid worked well for the T-111 parent material specimens; however, in the partially oxidized specimens, considerable pitting and staining occurred in the oxygen-affected zone and in the transition zone between the oxygen-affected zone and the parent material. A chemical polish was developed for the partially oxidized specimens by adjusting the ratio of the acids to ten parts lactic acid, two parts nitric acid, and two parts hydrofluoric acid. This slowed the chemical attack on the oxygen-affected zone considerably and, with continuous swabbing, the pitting and stain could be avoided. The specimens were rinsed and checked occasionally on the metallograph to determine when the proper polish had been obtained. Some specimens required intermittent polishing times up to 1 / 2 hour. No relationship could be established between the oxygen content of the specimen and the time required for chemical polishing in the partially oxidized specimens. However, the microstructure of the transition zone was the most difficult to obtain, and specimens with uniform reaction zones across the width of the specimen polished quicker than those with the transition zone

Prevention of lymphocele by using gelatin-thrombin matrix as a tissue sealant after pelvic lymphadenectomy in patients with gynecologic cancers: a prospective randomized controlled study.

This prospective randomized controlled pilot study aimed to find whether gelatin-thrombin matrix used as a tissue sealant (FloSeal) can prevent the occurrence of pelvic lymphocele in patients with gynecologic cancer who has undergone pelvic lymphadenectomy. Each patient, who undergo a laparotomic pelvic lymph node dissection on both sides, was randomly assigned for FloSeal application on 1 side of the pelvis. The other side of the pelvis without any product application being the control side. The amount of lymph drainage at each side of the pelvis was measured for 3 days, and computed tomography scans were obtained 7 days and 6 months after surgery for detection of pelvic lymphocele. Among 37 cases, the median amount of lymph drainage was significantly decreased in the hemi-pelvis treated with FloSeal compared to the control hemi-pelvis (p=0.025). The occurrence of lymphocele was considerably reduced in treated hemi-pelvis (8/37, 21.6%) compared with control hemi-pelvis (12/37, 32.4%) after 7 post-operative days (p=0.219), and more decreased in the treated hemi-pelvis (5/37, 13.5%) compared with control hemi-pelvis (9/37, 24.3%) after postoperative 6 months (p=0.344). The application of FloSeal as a tissue sealant in lymph nodes resected tissues can reduce the incidence of pelvic lymphocele in gynecologic cancer patients. A large randomized controlled study could confirm these preliminary results. Copyright © 2017. Asian Society of Gynecologic Oncology, Korean Society of Gynecologic Oncology

Graphite Composite Panel Polishing Fixture

Science.gov (United States)

Hagopian, John; Strojny, Carl; Budinoff, Jason

2011-01-01

The use of high-strength, lightweight composites for the fixture is the novel feature of this innovation. The main advantage is the light weight and high stiffness-to-mass ratio relative to aluminum. Meter-class optics require support during the grinding/polishing process with large tools. The use of aluminum as a polishing fixture is standard, with pitch providing a compliant layer to allow support without deformation. Unfortunately, with meter-scale optics, a meter-scale fixture weighs over 120 lb (.55 kg) and may distort the optics being fabricated by loading the mirror and/or tool used in fabrication. The use of composite structures that are lightweight yet stiff allows standard techniques to be used while providing for a decrease in fixture weight by almost 70 percent. Mounts classically used to support large mirrors during fabrication are especially heavy and difficult to handle. The mount must be especially stiff to avoid deformation during the optical fabrication process, where a very large and heavy lap often can distort the mount and optic being fabricated. If the optic is placed on top of the lapping tool, the weight of the optic and the fixture can distort the lap. Fixtures to support the mirror during fabrication are often very large plates of aluminum, often 2 in. (.5 cm) or more in thickness and weight upwards of 150 lb (68 kg). With the addition of a backing material such as pitch and the mirror itself, the assembly can often weigh over 250 lb (.113 kg) for a meter-class optic. This innovation is the use of a lightweight graphite panel with an aluminum honeycomb core for use as the polishing fixture. These materials have been used in the aerospace industry as structural members due to their light weight and high stiffness. The grinding polishing fixture consists of the graphite composite panel, fittings, and fixtures to allow interface to the polishing machine, and introduction of pitch buttons to support the optic under fabrication.

Full Text Available The aim of this paper is to present the socio-economic and spatial transformation of Polish cities after 1989. The Polish changes reached the structures of the three basic subsystems of the state: political (power, social (society, and economic (the economy. The systemic transformation that has taken place in Poland after 1989 is most readily visible in towns, although it was introduced in the country as a whole. For the development and transforma-tion of towns, the most important were the introduction of local government structures and the market model of the economy. The restitution of local government has ensured towns an authentic manager authorised to perform his function by the local community. The in-troduction of the market model to the economy has resulted in its privatisation and the ap-pearance of enterprise and competition. Towns, especially the biggest cities, have become attractive locations for investment. Cities with a balanced economic structure and well-de-veloped infrastructure had much better chances for growth to start with. Unfortunately, the transformation period has also had some detrimental effects, the most important being un-employment and all kinds of social deviance. However, Polish cities are certainly different today and resemble Western cities to a greater extent than did the so-called socialist towns built along theoretically beautiful but practically ineffectual ideological lines.

Assessing operability of a novel polisher arrangement using MMS

International Nuclear Information System (INIS)

Shor, S.W.W.

1987-01-01

A condensate polisher is intended to remove both particulate matter and ionic material from the condensate. Condensate polishers have normally been placed directly in the condensate system downstream of the condensate pumps. This inline location has certain disadvantages. These disadvantages are discussed. Placing the polisher in a sidestream location, where water is removed from the condensate system, pumped through the polisher, and then returned to the condensate system provides a solution to these disadvantages. Several possible types of sidestream installations is described. This has a polisher taking unpolished condensate from one compartment from one compartment of a divided hotwell in a specially modified condenser and returning polished condensate to the other compartment. The polisher is supplied by its own dedicated pumps, which have a head requirement sufficient only to overcome the pressure drop through the polisher circuit at a flow rate of 110% of maximum condensate flow. This concept is very attractive but has not yet been tested even though it is being installed in several new units. A simulation was, therefore, performed using MMS to provide confidence that this particular sidestream polisher arrangement was operationally viable

Laser-based additive manufacturing has attracted much attention as a promising 3D printing method for metallic components in recent years. However, surface roughness of additive manufactured components has been considered as a challenge to achieve high performance. In this work, we demonstrate the capability of fiber laser in polishing rough surface of additive manufactured Ti-based alloys as Ti-6Al-4V and TC11. Both as-received surface and laser-polished surfaces as well as cross-section subsurfaces were analyzed carefully by White-Light Interference, Confocal Microscope, Focus Ion Beam, Scanning Electron Microscopy, Energy Dispersive Spectrometer, and X-ray Diffraction. Results revealed that as-received Ti-based alloys with surface roughness more than 5 μm could be reduce to less than 1 μm through laser polishing process. Moreover, microstructure, microhardness and wear resistance of laser-polished zone was investigated in order to examine the thermal effect of laser polishing processing on the substrate of additive manufactured Ti alloys. This proof-of-concept process has the potential to effectively improve the surface roughness of additive manufactured metallic alloy by local polishing method without damage to the substrate.

Ferocious Enemies and Noble Heroes: Images of “Us” and “Them” in Polish American Textbooks (until the 1930s

Full Text Available Ethnic schools had an important role to play in propagating profiles of “ideal” heroes and members of society among immigrant communities. Consequently, it was often the role of school coursebooks to inform pupils of the messages adults wanted to transmit to the younger generation. In this paper the author attempts to describe contents of various textbooks used in Polish-American parochial schools. Invention of national mythology and simplification of facts was necessary to facilitate the memorizing process as required. But to form group solidarity one also had to identify common enemies. Various textbooks published in the U.S.A. before World War I did not help immigrants’ children to acculturate to their American realities. Being very didactic, they focused mainly on Polish realities and Polish history. Only after World War I did an American presence become more visible in books used in the first grade. In thirties Felicians predominantly used textbooks written in the U.S.A., mainly by S. M. Cyryla (Magdalena Tobaka. The heroes they presented were characterized schematically, and the ideals found therein were alien to Polish-American children. Polska by S. Mary Cyryla, was the book on which this analysis was based. The image of Poles and “other” nations is surprisingly defined in black and white. Foreign nations are depicted as cruel, monstrous, villain, pagan, barbaric, etc. “Us”, the Poles, are seen as brave, just, good, wise, honest, faithful, etc., they “have loved faith, country, and language” etc. Cyryla’s textbook tried to engender feelings of community by dividing the world into “us” and “them”, thereby provoking antagonism towards “them.” Polish personality traits were very much in keeping with the images and self-stereotypes which Polish society had about itself. In constructing a positive and ideal self-image, it was useful for “others” and “strangers” to be depicted as “enemies”. �

Full Text Available Robotic laparoscopy in gynecology, which started in 2005 when the Da Vinci Surgical System (Intuitive Surgical Inc was approved by the US Food and Drug Administration for use in gynecologic procedures, represents today a modern, safe, and precise approach to pathology in this field. Since then, a great deal of experience has accumulated, and it has been shown that there is almost no gynecological surgery that cannot be approached with this technology, namely hysterectomy, myomectomy, sacrocolpopexia, and surgery for the treatment of endometriosis. Albeit no advantages have been observed over conventional laparoscopy and some open surgical procedures, robotics do seem to be advantageous in highly complicated procedures when extensive dissection and proper anatomy reestablishment is required, as in the case of oncologic surgery. There is no doubt that implementation of better logistics in finance, training, design, and application will exert a positive effect upon robotics expansion in gynecological medicine. Contrary to expectations, we estimate that a special impact is to be seen in emerging countries where novel technologies have resulted in benefits in the organization of health care systems.

Immunotherapy in Gynecologic Cancers: Are We There Yet?

Pakish, Janelle B; Jazaeri, Amir A

2017-08-24

Immune-targeted therapies have demonstrated durable responses in many tumor types with limited treatment options and poor overall prognosis. This has led to enthusiasm for expanding such therapies to other tumor types including gynecologic malignancies. The use of immunotherapy in gynecologic malignancies is in the early stages and is an active area of ongoing clinical research. Both cancer vaccines and immune checkpoint inhibitor therapy continue to be extensively studied in gynecologic malignancies. Immune checkpoint inhibitors, in particular, hold promising potential in specific subsets of endometrial cancer that express microsatellite instability. The key to successful treatment with immunotherapy involves identification of the subgroup of patients that will derive benefit. The number of ongoing trials in cervical, ovarian, and endometrial cancer will help to recognize these patients and make treatment more directed. Additionally, a number of studies are combining immunotherapy with standard treatment options and will help to determine combinations that will enhance responses to standard therapy. Overall, there is much enthusiasm for immunotherapy approaches in gynecologic malignancies. However, the emerging data shows that with the exception of microsatellite unstable tumors, the use of single-agent immune checkpoint inhibitors is associated with response rates of 10-15%. More effective and likely combinatorial approaches are needed and will be informed by the findings of ongoing trials.

Kuznetsova, Irina A.; Gladkova, Natalia D.; Gelikonov, Valentin M.; Belinson, Jerome L.; Shakhova, Natalia M.; Feldchtein, Felix I.

Timely and efficient diagnosis of diseases of the female reproductivesystem is very important from the social viewpoint [1, 2]. Diagnosticefficacy of the existing techniques still needs improvement sincemalignant neoplasms of the female reproductive system organs are stableleaders among causes of death (over 35.9 %) [3]. Each year, 851.9 thousand genital cancer cases are recorded worldwide [1, 2]. However, the diagnostic efficacy of the visual examination with biopsy is limited. Correct interpretation of colposcopic features requires high skills and long-term clinical experience, which makes colposcopy very subjective and limits interobserver agreement [8-10]. OCT is known to visualize in vivo and noninvasively tissue microstructure with spatial resolution approaching the histologic level and therefore can be expected to guide biopsies and to provide real-time tissue structure information when biopsies are contraindicated or impractical. Although thorough clinical studies are required to determine if OCT can be suitable for this purpose in gynecology in general and for cervical cancer in particular, the early results look encouraging. In this chapter, we present a wide spectrum of the OCT studies of different partsof the female reproductive system and demonstrate the potential of the clinical use of this new visualization method in gynecological practice.

MR imaging and PET using 2-Deoxy-2-[ 18 F]fluoroglucose (FDG) are both useful in the evaluation of gynecologic malignancies. MR imaging is superior for local staging of disease whereas fludeoxyglucose FDG PET is superior for detecting distant metastases. Integrated PET/MR imaging scanners have great promise for gynecologic malignancies by combining the advantages of each modality into a single scan. This article reviews the technology behind PET/MR imaging acquisitions and technical challenges relevant to imaging the pelvis. A dedicated PET/MR imaging protocol; the roles of PET and MR imaging in cervical, endometrial, and ovarian cancers; and future directions for PET/MR imaging are discussed.

Full text: Russia is a potent producer of polishing powders made of rare earth material presented as an extensive and well developed base. Considering the reserves, the facilities predisposition and the polishing agent (cerium dioxide) content the chief mineral source is loparite, apatite and monazite. The production of rare earth polishing powders is based on specially developed continuous technological processes, corrosion-proof equipment, ensuring a high and stable production quality. A special attention is paid to the radiation safety of the powders. The initial material for the rare earth polishing powders based on loparite is the fusion cake of rare earth chlorides obtained at that mineral chlorination. The technology of the polishing powder production from the REE fusion cake includes the following stages: dissolution of the REE fusion cake chlorides; - thorough cleaning of the REE fusion cake chlorides from radioactive and non-rare-earth impurities; chemical precipitation of REE carbonates, obtaining middlings with proper material and granulometric composition, thermal treatment of precipitated carbonates followed with the operations of drying and roasting; classification of roasted oxides, obtaining end products - polishing powders. The production of fluorine-containing powders includes the stage of their fluorination after the stage of carbonate precipitation. The stabilizing doping can be introduced both into the middlings during one of the technological process of powders manufacturing and into the end product. Rare earth polishing powders are manufactured in Russia by the Share Holding Company 'Chepetz Mechanical Plant' (ChMP Co.), the city of Glasov. The plant produces a number of polishing materials, such as; polishing powder Optinol, containing at least 50% by mass of cerium dioxide, used in the mass production of optical and other articles; polishing powder Optinol-10 with doping to improve the sedimentary and aggregate stability of the solid phase

2004-01-01

Despite improvements in surgical instrumentation and techniques, adhesions continue to form after most procedures. Peritoneal adhesions develop in 60-90% of women who undergo major gynecological operations. This adhesion formation causes significant postoperative morbidity such as bowel obstruction (65%), infertility (15-20%), and chronic pelvic pain (40%). To demonstrate the efficacy of a hyaluronic acid product (Hyalobarrier Gel) for the prevention of adhesions in gynecological surgery. From October 2000 to July 2002, 18 women from 26 to 41 years old (mean age 33.66) underwent myomectomy via laparotomy as their first abdominal operation. Between August 2001 and May 2003, the patients underwent a second-look laparoscopy (7 women, 38.9%, 15 sites, 42.8%) or a second-look laparotomy (11 women, 61.1%, 20 sites, 57.1%) during which all the 35 sites corresponding to the previous myomectomies were analyzed. During the second-look procedure the presence, localization and severity of adhesions were evaluated using the Operative Laparoscopy Study Group Classification (OLSG) and American Fertility Society Classification (AFSC). All patients underwent a second-look laparoscopy/laparotomy and only five of 18 (27.7%) showed pelvic adhesions in seven sites (20%) of previous myomectomies. No adhesion was found on the previous sites of myomectomies of pedunculated leiomyomas so, excluding those, adhesions were found in seven of 29 sites of myomectomies (24.1%). The present study emphasizes the need for improved treatments to prevent adhesions, as there is no doubt that adhesions represent one of the major causes of female morbidity.

We sought to describe practice patterns, attitudes, and barriers to the integration of palliative care services by gynecologic oncologists. Members of the Society of Gynecologic Oncology were electronically surveyed regarding their practice of incorporating palliative care services and to identify barriers for consultation. Descriptive statistics were used, and two-sample z-tests of proportions were performed to compare responses to related questions. Of the 145 respondents, 71% were attending physicians and 58% worked at an academic medical center. The vast majority (92%) had palliative care services available for consultation at their hospital; 48% thought that palliative care services were appropriately used, 51% thought they were underused, and 1% thought they were overused. Thirty percent of respondents thought that palliative care services should be incorporated at first recurrence, whereas 42% thought palliative care should be incorporated when prognosis for life expectancy is ≤ 6 months. Most participants (75%) responded that palliative care consultation is reasonable for symptom control at any stage of disease. Respondents were most likely to consult palliative care services for pain control (53%) and other symptoms (63%). Eighty-three percent of respondents thought that communicating prognosis is the primary team's responsibility, whereas the responsibilities for pain and symptom control, resuscitation status, and goals of care discussions were split between the primary team only and both teams. The main barrier for consulting palliative care services was the concern that patients and families would feel abandoned by the primary oncologist (73%). Ninety-seven percent of respondents answered that palliative care services are useful to improve patient care. The majority of gynecologic oncologists perceived palliative care as a useful collaboration that is underused. Fear of perceived abandonment by the patient and family members was identified as a

Combined surgery is an attractive option for both patients and surgeons. Unfortunately, it remains unclear to patients whether plastic surgery can be combined safely and efficaciously with other surgeries, particularly gynecologic surgery. The goal of this study was to determine the safety and efficacy of combined abdominoplasty and gynecologic surgery. A case-control study of 25 patients undergoing combined abdominoplasty and intra-abdominal gynecologic surgery was performed. These combined patients were compared with control group patients undergoing abdominoplasty alone and gynecologic surgery alone. Demographic data, operative time, estimated blood loss, pre- and postoperative hemoglobin, length of hospitalization, and complications were compared between combined and control groups. Statistically significant reductions were seen in operative time, estimated blood loss, and total days of hospitalization when comparing the combined group to the sum of the control groups. In this study, no major complications, including the need for blood transfusion or pulmonary embolus, were noted in any of the patients. These results demonstrate success in performing abdominoplasty with gynecologic surgery, which may be an acceptable option for patients.

Several diseases and medications are known to induce secondary osteoporosis. Among them, same situations are related to gynecological field. They include Turner's syndrome, anorexia nervosa, ovarian dysfunction, oophorectomy, GnRH agonist therapy, and osteoporosis associated with pregnancy. We briefly describe these secondary osteoporosis in this article as follows. Several studies have found osteoporosis to be a common complication of Turner's syndrome and hormone replacement therapy has been used as a possible management; in anorexic patient, low body weight, prolonged amenorrhea, early onset of anorexia nervosa, and hypercortisolism have been reported to be risks for bone demineralization; since oophorectomy which is a common intervention in gynecology leads osteoporosis, it is important to prevent osteoporosis caused by surgery as well as postmenopausal osteoporosis; GnRH agonist, which induces estrogen deficient state and affect bone mass, is commonly used as a management for endometriosis and leiomyoma of uterus; associated with pregnancy, post-pregnancy spinal osteoporosis and transient osteoporosis of the hip are clinically considered to be important and heparin therapy and magnesium sulfate therapy are commonly employed during pregnancy, affecting calcium homeostasis.

Polishing of silicon based advanced ceramics

Klocke, Fritz; Dambon, Olaf; Zunke, Richard; Waechter, D.

2009-05-01

Silicon based advanced ceramics show advantages in comparison to other materials due to their extreme hardness, wear and creep resistance, low density and low coefficient of thermal expansion. As a matter of course, machining requires high efforts. In order to reach demanded low roughness for optical or tribological applications a defect free surface is indispensable. In this paper, polishing of silicon nitride and silicon carbide is investigated. The objective is to elaborate scientific understanding of the process interactions. Based on this knowledge, the optimization of removal rate, surface quality and form accuracy can be realized. For this purpose, fundamental investigations of polishing silicon based ceramics are undertaken and evaluated. Former scientific publications discuss removal mechanisms and wear behavior, but the scientific insight is mainly based on investigations in grinding and lapping. The removal mechanisms in polishing are not fully understood due to complexity of interactions. The role of, e.g., process parameters, slurry and abrasives, and their influence on the output parameters is still uncertain. Extensive technological investigations demonstrate the influence of the polishing system and the machining parameters on the stability and the reproducibility. It is shown that the interactions between the advanced ceramics and the polishing systems is of great relevance. Depending on the kind of slurry and polishing agent the material removal mechanisms differ. The observed effects can be explained by dominating mechanical or chemo-mechanical removal mechanisms. Therefore, hypotheses to state adequate explanations are presented and validated by advanced metrology devices, such as SEM, AFM and TEM.

Chemical mechanical polishing (CMP) is the primary method to realize the global planarization of silicon wafer. In order to improve this process, a novel method which combined megasonic vibration to assist chemical mechanical polishing (MA-CMP) is developed in this paper. A matching layer structure of polishing head was calculated and designed. Silicon wafers are polished by megasonic assisted chemical mechanical polishing and traditional chemical mechanical polishing respectively, both coarse polishing and precision polishing experiments were carried out. With the use of megasonic vibration, the surface roughness values Ra reduced from 22.260nm to 17.835nm in coarse polishing, and the material removal rate increased by approximately 15-25% for megasonic assisted chemical mechanical polishing relative to traditional chemical mechanical polishing. Average Surface roughness values Ra reduced from 0.509nm to 0.387nm in precision polishing. The results show that megasonic assisted chemical mechanical polishing is a feasible method to improve polishing efficiency and surface quality. The material removal and finishing mechanisms of megasonic vibration assisted polishing are investigated too. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available Finishing process like polishing is usually used to obtain high quality mechanical surface characteristics such as texture and roughness. These operations are mainly handmade and need highly trained operators thus limiting their repeatability and profitability. To optimize the industrialization of the polishing process, it is therefore necessary to modelize the process to built efficient parameter database. The aim of this study is to characterise the polishing of 316L stainless steel with structured abrasive belts. The geometric data of the belts are given, and we then propose a model to determine material removal. An experimental test bench is set up to test this model and characterise the polishing process in terms of forces. It produces samples for different polishing conditions. The different polished surfaces are then analyzed thanks to the roughness and the wettability. Using experimental designs, we are able to validate the proposed model and identify the parameters that influence a polishing operation.

The Japan Society of Obstetrics and Gynecology (JSOG) implemented an assisted reproductive technology (ART) registry system in 1986. Here are reported the characteristics and treatment outcomes of ART cycles that were registered in 2015. JSOG has requested all participating ART facilities to register cycle-specific information for all ART cycles since 2007. A descriptive analysis was performed by using the registry database for 2015. In total, 424 151 cycles and 51 001 neonates (1 in 19.7 neonates born in Japan) were registered in 2015. The patients' mean age was 38.2 years (standard deviation = 4.5). Among the fresh cycles, 94 158 of 244 718 (38.5%) egg retrieval cycles were cycles with freeze-all embryos or oocytes, while fresh embryo transfer (ET) was performed in 70 254 cycles, signaling a decrease from 2014. There were 169 898 frozen-thawed ET cycles, resulting in 56 355 pregnancies and 40 599 neonates. Single ET was performed at a rate of 79.7% for fresh and 81.8% for frozen cycles and the singleton pregnancy/live birth rates were 96.9%/96.5% and 96.8%/96.4% for the respective cycles. The total ART cycles and live births resulting from ART has been increasing in Japan. Single ET was performed at a rate of almost 80% and ET cycles have shifted from fresh to frozen cycles.

Full Text Available Abstract Background Surgical site infections (SSI are one of the most common healthcare associated infections in the low-middle income countries. Data on incidence and risk factors for SSI following surgeries in general and Obstetric and Gynecological surgeries in particular are scare. This study set out to identify risk factors for SSI in patients undergoing Obstetric and Gynecological surgeries in an Indian rural hospital. Methods Patients who underwent a surgical procedure between September 2010 to February 2013 in the 60-bedded ward of Obstetric and Gynecology department were included. Surveillance for SSI was based on the Centre for Disease Control (CDC definition and methodology. Incidence and risk factors for SSI, including those for specific procedure, were calculated from data collected on daily ward rounds. Results A total of 1173 patients underwent a surgical procedure during the study period. The incidence of SSI in the cohort was 7.84% (95% CI 6.30–9.38. Majority of SSI were superficial. Obstetric surgeries had a lower SSI incidence compared to gynecological surgeries (1.2% versus 10.3% respectively. The risk factors for SSI identified in the multivariate logistic regression model were age (OR 1.03, vaginal examination (OR 1.31; presence of vaginal discharge (OR 4.04; medical disease (OR 5.76; American Society of Anesthesia score greater than 3 (OR 12.8; concurrent surgical procedure (OR 3.26; each increase in hour of surgery, after the first hour, doubled the risk of SSI; inappropriate antibiotic prophylaxis increased the risk of SSI by nearly 5 times. Each day increase in stay in the hospital after the surgery increased the risk of contacting an SSI by 5%. Conclusions Incidence and risk factors from prospective SSI surveillance can be reported simultaneously for the Obstetric and Gynecological surgeries and can be part of routine practice in resource-constrained settings. The incidence of SSI was lower for Obstetric surgeries

Along with the development of medicine, increasingly significant role has been played by the laboratory diagnostics. For over ten years the profession of the medical laboratory specialist has been regarded in Poland as the autonomous medical profession and has enjoyed a status of one of public trust. The process of education of medical laboratory specialists consists of a five-year degree in laboratory medicine, offered at Medical Universities, and of a five-year Vocational Specialization in one of the fields of laboratory medicine such as clinical biochemistry, medical microbiology, medical laboratory toxicology, medical laboratory cytomorphology and medical laboratory transfusiology. An important component of medical laboratory specialists' identity is awareness of inherited ethos obtained from bygone generations of workers in this particular profession and the need to continue its further development. An expression of this awareness is among others Polish Code of Ethics of a Medical Laboratory Specialist (CEMLS) containing a set of values and a moral standpoint characteristic of this type of professional environment. Presenting the ethos of the medical laboratory specialist is a purpose of this article. Authors focus on the role CEMLS plays in areas of professional ethics and law. Next, they reconstruct the Polish model of ethos of medical diagnostic laboratory personnel. An overall picture consists of a presentation of the general moral principles concerning execution of this profession and rules of conduct in relations with the patient, own professional environment and the rest of the society. Polish model of ethical conduct, which is rooted in Hippocratic medical tradition, harmonizes with the ethos of medical laboratory specialists of other European countries and the world.

Therapeutic intervention in a course of illness, while producing the desired result, also may have some adverse long-term effects on the patient. Second malignancies are one of the known complications of therapy. The treatments of gynecologic cancers by surgery, irradiation and chemotherapy have been associated with subsequent neoplasms. Care must be exercised in associating previous therapy and a subsequent malignancy. Naturally occurring second cancers must be separated from those which are iatrogenic. Associations in the literature have been made involving malignancies as a sequelae of prior gynecologic therapy. The use of normal skin from the thigh to fabricate an artificial vagina has resulted in more squamous cell carcinomas than expected. Alkylating agents used in the treatment of ovarian cancer and other diseases have been shown to lead to an increased risk of leukemia. Irradiation therapy, however, has not yet been shown to be related to leukemia in cervical cancer patients. The incidence of lymphoma and uterine, urinary bladder and colon carcinomas has been associated with prior irradiation for gynecologic disease. The literature regarding the therapeutically induced risk factors in gynecologic therapy is reviewed and areas of our knowledge that require more investigation are identified

Polishing procedures might alter monolithic zirconia (MZ) surface resulting in phase changes that can be deleterious for clinical performance and antagonist tooth wear. This study investigated the topographical features and phase transformation in MZ after polishing with different regimens simulating the clinical workflow. ​ MZ specimens (Katana Zirconia HT, Kuraray-Noritake) (12×12×1.8 mm(3)) were grinded and polished using one of the five systems assessed: BG: Silicone carbide polishers (Brownie, Greenie, Super Greenie); CG: Diamond impregnated ceramic polisher kit (Ceragloss); EV: Synthetically bonded grinder interspersed with diamond (EVE Kit); SL: Urethane coated paper with aluminium oxide grits (Soflex Finishing and Polishing System Kit) and DB: Diamond bur (8 µm). Polished specimens were initially roughened with 220 µm diamond burs (Grinding Bur-GB) (10 s, 160.000160,000 rpm) and considered for baseline measurements. Polishing regimens were performed for 10 s using a slow-speed hand piece under water-cooling except for SL, in a custom made device (750 g; 5000 and 75,000 rpm). Surface roughnesses, phase changes (XRD) were assessed, surface characterization was performed (SEM, EDS). The highest roughness was obtained with the EV system (1.11 µm) compared to those of other systems (0.13-0.4 µm) (pθ and minor peak at 34.94°2θ. While GB, CG, EV, SL and DB exhibited a peak shift to the left, BG demonstrated a right peak shift on the 2θ scale. Monoclinic phase change was not noted in any of the groups. All polishing methods, except BG, exhibited a peak shift towards the lower angles of the 2-theta scale. Since the peak shifts were in the order of fractions of an angle they are attributed to stress formation rather than a phase change in the material. Thus, all polishing systems tested may not be detrimental for the phase transformation of MZ. EV system resulted in the highest roughness and none of the polishing regimens restored the polishability to the

This text describes the leaders who established the modem obstetrics and gynecology for Taiwan. during the Japan-colonizing period (1895-1945). These leaders are Mr. Kawasoye, M., Mr. Mukae K., and Mr. Magara M. The lives of these leaders were different, but they all strongly contributed to the development of modem obstetrics and gynecology in Taiwan. With regard to the passage of time, Mr. Kawasoye contributed the initial efforts, Mr. Mukae worked during the flourishing period of the clinic; and Mr. Magara worked during the mature period, emphasizing research. These three periods are closely correlated with the course of the development of modem obstetrics and gynecology in Taiwan.

Prophylactic intraoperative ureteral stent placement is performed to decrease operative ureteric injury, though few data are available on the effectiveness of this procedure, and no data are available on its cost. To analyze the cost of prophylactic intraoperative cystoscopic ureteral stents in gynecologic surgery. All cases of prophylactic ureteral stent placement performed in gynecologic surgery during a 1-year period were identified and retrospectively reviewed through the electronic medical records database of Summa Health System. Costs were obtained through the Healthcare Cost Accounting System. The principles of cost-effective analysis were used (ie, explicit and detailed descriptions of costs and cost-effectiveness statistics). Importantly, we evaluated cost and not charges or financial model estimates. In addition, we obtained the contribution margins (ie, the hospital's net profit or loss) for prophylactic ureteral stent placement. Other gynecologic procedures were also analyzed. Among 792 major inpatient gynecologic procedures, 18 cases of prophylactic intraoperative ureteral stents were identified. Median costs were as follows: additional cost of prophylactic intraoperative ureteral stenting, $1580; additional cost of surgical resources, $770; cost of ureteral catheters, $427; cost of surgeons, $383. The contribution margins per case for various gynecologic surgical procedures were as follows: oophorectomy, $2804 profit; abdominal hysterectomy, $2649 profit; laparoscopically assisted vaginal hysterectomy (LAVH), $1760 profit. When intraoperative ureteral stenting was added, the contribution margins changed to the following: oophorectomy, $782 profit; abdominal hysterectomy, $627 profit; LAVH, $262 loss. Overall, the contribution margin profit was decreased by about 85%, from $2400 to $380. Prophylactic intraoperative ureteral stenting in gynecologic surgery decreases a hospital's contribution margin. Because of the expense of this procedure, as well as

Figures of two outstanding orthopaedists Professor Stefan Malawski and Professor Jerzy Król rewarded with the medal of the name of Wiktor Degi were described. The medal is being granted by the Chapter of the Medal as regarding for outstanding achievements for the Polish and world orthopaedics and rehabilitation. Profesor Stefan Kazimierz Malawski was born 26. 12. 1920 in the Vilnius area. In Vilnius he stated his medical studies, which he continued in Lwow and graduated in 1946 at the Marie Curie Skłodowska in Lublin. Professor Malawski's main field of interest were related to the problems related to tuberculosis of bones and joints and trauma of the lumbar and cervical spine. In the problems of bone tuberculosis he remains an unquestioned authority in Poland. His deep understanding of these clinical problems can be found in his text-book "Tuberculosis of bones and joints", which was printed in 1976. The information pertaining diagnosis and surgical treatment remain extremely valuable today. Another field of interest of Professor Malawski are pathologies of the spine. Disc disease, neoplasms of the spine, spinal stenosis and infections of the spine, spondylolisthesis are among many of his interests. This very wide field of interest can be dound in his 3 tome publication Spondyloorthopedics. His 166 papars printed in Poland and abroad bear proof of the Professors wide field of interest and deep knowledge. Professor Malawski was the first surgeon in Poland to perform surgery on the front elements of the spine in tuberculotic paraplegia. In 1958 he implemented surgical treatment of spine tumor--both primary and metastatic, by resecting them and stabilizing the spine with grafts. In the early 70's he focused on spinal stenosis. In the years 1982-1986 he was the Chairman of the Board of the Polish Orthopedic and Trauma Society. Professor Malawski introdued a modern set of Rules and Regulations, greatly simplifying the decision making process during General assemblies

Highlights: • Process optimisation for laser polishing novel 3D printed SS316L parts. • Evaluating the effects of key polishing parameters on SS316L surface roughness. • Detailed spectroscopic analysis of oxide layer formation due to laser polishing. • Comparative surface integrity analysis of SS parts polished in air and argon. • A maximum reduction in roughness of over 94% achieved at optimised polishing settings. - Abstract: Laser polishing of various engineered materials such as glass, silica, steel, nickel and titanium alloys, has attracted considerable interest in the last 20 years due to its superior flexibility, operating speed and capability for localised surface treatment compared to conventional mechanical based methods. The paper initially reports results from process optimisation experiments aimed at investigating the influence of laser fluence and pulse overlap parameters on resulting workpiece surface roughness following laser polishing of planar 3D printed stainless steel (SS316L) specimens. A maximum reduction in roughness of over 94% (from ∼3.8 to ∼0.2 μm S_a) was achieved at the optimised settings (fluence of 9 J/cm"2 and overlap factors of 95% and 88–91% along beam scanning and step-over directions respectively). Subsequent analysis using both X-ray photoelectron spectroscopy (XPS) and glow discharge optical emission spectroscopy (GDOES) confirmed the presence of surface oxide layers (predominantly consisting of Fe and Cr phases) up to a depth of ∼0.5 μm when laser polishing was performed under normal atmospheric conditions. Conversely, formation of oxide layers was negligible when operating in an inert argon gas environment. The microhardness of the polished specimens was primarily influenced by the input thermal energy, with greater sub-surface hardness (up to ∼60%) recorded in the samples processed with higher energy density. Additionally, all of the polished surfaces were free of the scratch marks, pits, holes, lumps

The growing popularity and acceptance of integrative medicine is evident both among patients and among the oncologists treating them. As little data are available regarding health-care professionals' knowledge, attitudes, and practices relating to the topic, a nationwide online survey was designed. Over a period of 11 weeks (from July 15 to September 30, 2014) a self-administered, 17-item online survey was sent to all 676 members of the Research Group on Gynecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie) in the German Cancer Society. The questionnaire items addressed the use of integrative therapy methods, fields of indications for them, advice services provided, level of specific qualifications, and other topics. Of the 104 respondents (15.4%) using integrative medicine, 93% reported that integrative therapy was offered to breast cancer patients. The second most frequent type of tumor in connection with which integrative therapy methods were recommended was ovarian cancer, at 80% of the participants using integrative medicine. Exercise, nutritional therapy, dietary supplements, herbal medicines, and acupuncture were the methods the patients were most commonly advised to use. There is considerable interest in integrative medicine among gynecological oncologists, but integrative therapy approaches are at present poorly implemented in routine clinical work. Furthermore there is a lack of specific training. Whether future efforts should focus on extending counseling services on integrative medicine approaches in gynecologic oncology or not, have to be discussed. Evidence-based training on integrative medicine should be implemented in order to safely guide patients in their wish to do something by themselves.

The aim of the study was to analyze the current management of endometrial cancer across Spain and to evaluate the use and applicability of the national and international guidelines. An electronic 30-question survey was distributed among all Spanish Society of Obstetrics and Gynecology-registered specialists dedicated to gynecologic oncology in Spain by e-mail. Data were collected anonymously and analyzed using SPSS program. One hundred forty-five (17.8%) surveys were collected. Significant differences were observed between tertiary hospitals and secondary or private hospitals in terms of appropriate (according to European Society of Gynaecologic Oncology guidelines) nodal staging in low-risk cases (96 [95%] vs 27 [61.4%], respectively; P comparing centers with less than 20 cases per year to centers with more than 40 cases annually, with significant differences in the management of low-risk and intermediate-risk endometrial cancers. This cross-sectional study demonstrates a broad heterogeneity of care giving between the clinical national and international guidelines and the actual practice in Spain. Although most of the responders refer to base their endometrial cancer management on Spanish and European Society of Gynaecologic Oncology guidelines (64.1%), many discrepancies have been observed, mainly in the management of intermediate-risk cases and follow-up. It may be caused by the lack of consensus on certain points, lack of facilities in lower case load centers, and also due to disagreement or unawareness on the current knowledge.

Full Text Available The purpose of this study was to investigate the effect of different polishing methods on color stability of posterior, universal and nanohybrid composite resin restorative materials upon exposure to a staining agent. Twenty-five specimens were prepared for each of 5 different composite resins (Filtek Z250, Filtek P60, Quadrant LC, Grandio and Filtek Supreme. Specimens were divided into 5 groups and different polishing procedures, including polishing discs (Pd, polishing discs then diamond polishing paste (PdP, polishing discs then a liquid polishing system (Biscover (PdB, and combinations of these (PdPB were used. Unpolished specimens served as the control (C. The specimens were stored for 48 h in a coffee solution. The color of all specimens was measured before and after exposure with a colorimeter, and total color change (DE* were calculated. The data were analyzed with a two-way ANOVA and the means were compared by Tukey HSD test (a=0.05. The lowest color difference was observed in the groups PdP and C, while the highest color difference was observed in PdPB, and PdB. When comparing the five different restorative materials, no significant difference was observed between FiltekP60 and FiltekZ250, and these materials demonstrated significantly less color change than Quadrant LC and the nanohybrid materials (Grandio, Filtek Supreme. The posterior (Filtek P60 and universal (Filtek Z250 composite resin restorative materials, which do not contain tetraethyleneglycol dimethacrylate (TEGDMA, were found to be less stainable than the nanohybrid (Grandio, Filtek Supreme and universal (Quadrant LC composite resins, which contain TEGDMA. The use of diamond polishing paste after polishing with polishing discs significantly decreased staining when compared to the groups that used polishing discs alone, for all restorative materials tested. The highest color change values were obtained for the specimens that were polished with the Biscover liquid polish

Full Text Available OBJECTIVE: Patient chances for cure and palliation for a variety of malignancies may be greatly affected by the care provided by a treating hospital. We sought to determine the effect of volume and teaching status on patient outcomes for five gynecologic malignancies: endometrial, cervical, ovarian and vulvar carcinoma and uterine sarcoma. METHODS: The Florida Cancer Data System dataset was queried for all patients undergoing treatment for gynecologic cancers from 1990-2000. RESULTS: Overall, 48,981 patients with gynecologic malignancies were identified. Endometrial tumors were the most common, representing 43.2% of the entire cohort, followed by ovarian cancer (30.9%, cervical cancer (20.8%, vulvar cancer (4.6%, and uterine sarcoma (0.5%. By univariate analysis, although patients treated at high volume centers (HVC were significantly younger, they benefited from an improved short-term (30-day and/or 90-day survival for cervical, ovarian and endometrial cancers. Multivariate analysis (MVA, however, failed to demonstrate significant survival benefit for gynecologic cancer patients treated at teaching facilities (TF or HVC. Significant prognostic factors at presentation by MVA were age over 65 (HR = 2.6, p<0.01, African-American race (HR = 1.36, p<0.01, and advanced stage (regional HR = 2.08, p<0.01; advanced HR = 3.82, p<0.01, respectively. Surgery and use of chemotherapy were each significantly associated with improved survival. CONCLUSION: No difference in patient survival was observed for any gynecologic malignancy based upon treating hospital teaching or volume status. Although instances of improved outcomes may occur, overall further regionalization would not appear to significantly improve patient survival.

Full Text Available Amount of information transferred by computers grows very rapidly thus outgrowing the average man's capability of reception. It implies computer programs increase in the demand for which would be able to perform an introductory classitication or even selection of information directed to a particular receiver. Due to the complexity of the problem, we restricted it to understanding short newspaper notes. Among many conceptions formulated so far, the conceptual dependency worked out by Roger Schank has been chosen. It is a formal language of description of the semantics of pronouncement integrated with a text understanding algorithm. Substantial part of each text transformation system is a semantic parser of the Polish language. It is a module, which as the first and the only one has an access to the text in the Polish language. lt plays the role of an element, which finds relations between words of the Polish language and the formal registration. It translates sentences written in the language used by people into the language theory. The presented structure of knowledge units and the shape of understanding process algorithms are universal by virtue of the theory. On the other hand the defined knowledge units and the rules used in the algorithms ure only examples because they are constructed in order to understand short newspaper notes.

Smoking characteristics of Polish immigrants in Dublin.

LENUS (Irish Health Repository)

Kabir, Zubair

2008-01-01

BACKGROUND: This study examined two main hypotheses: a) Polish immigrants\\' smoking estimates are greater than their Irish counterparts (b) Polish immigrants purchasing cigarettes from Poland smoke "heavier" (>\\/= 20 cigarettes a day) when compared to those purchasing cigarettes from Ireland. The study also set out to identify significant predictors of \\'current\\' smoking (some days and everyday) among the Polish immigrants. METHODS: Dublin residents of Polish origin (n = 1,545) completed a previously validated Polish questionnaire in response to an advertisement in a local Polish lifestyle magazine over 5 weekends (July-August, 2007). The Office of Tobacco Control telephone-based monthly survey data were analyzed for the Irish population in Dublin for the same period (n = 484). RESULTS: Age-sex adjusted smoking estimates were: 47.6% (95% Confidence Interval [CI]: 47.3%; 48.0%) among the Poles and 27.8% (95% CI: 27.2%; 28.4%) among the general Irish population (p < 0.001). Of the 57% of smokers (n = 345\\/606) who purchased cigarettes solely from Poland and the 33% (n = 198\\/606) who purchased only from Ireland, 42.6% (n = 147\\/345) and 41.4% (n = 82\\/198) were "heavy" smokers, respectively (p = 0.79). Employment (Odds Ratio [OR]: 2.89; 95% CI: 1.25-6.69), lower education (OR: 3.76; 95%CI: 2.46-5.74), and a longer stay in Ireland (>24 months) were significant predictors of current smoking among the Poles. An objective validation of the self-reported smoking history of a randomly selected sub-sample immigrant group, using expired carbon monoxide (CO) measurements, showed a highly significant correlation coefficient (r = 0.64) of expired CO levels with the reported number of cigarettes consumed (p < 0.0001). CONCLUSION: Polish immigrants\\' smoking estimates are higher than their Irish counterparts, and particularly if employed, with only primary-level education, and are overseas >2 years.

Therapeutic intervention in a course of illness, while producing the desired result, also may have some adverse long-term effects on the patient. Second malignancies are one of the known complications of therapy. The treatments of gynecologic cancers by surgery, irradiation and chemotherapy have been associated with subsequent neoplasms. The use of normal skin from the thigh to fabricate an artificial vagina has resulted in more squamous cell carcinomas than expected. Alkylating agents used in the treatment of ovarian cancer and other diseases have been shown to lead to an increased risk of leukemia. The incidence of lymphoma and uterine, urinary bladder and colon carcinomas has been associated with prior irradiation for gynecologic disease. The literature regarding the therapeutically induced risk factors in gynecologic therapy is reviewed and areas of our knowledge that require more investigation are identified

We evaluated the efficacy and safety of the aromatase inhibitor exemestane in patients with advanced, persistent or recurrent endometrial carcinoma. We performed an open-label one-arm, two-stage, phase II study of 25 mg of oral exemestane in 51 patients with advanced (FIGO stage III-IV) or relapsed endometrioid endometrial cancer. Patients were stratified into subsets of estrogen receptor (ER) positive and ER negative patients. Recruitment to the ER negative group was stopped prematurely after 12 patients due to slow accrual. In the ER positive patients, we observed an overall response rate of 10%, and a lack of progression after 6 months in 35% of the patients. No responses were registered in the ER negative patients, and all had progressive disease within 6 months. For the total group of patients, the median progression free survival (PFS) was 3.1 months (95% CI: 2.0-4.1). In the ER positive patients the median PFS was 3.8 months (95% CI: 0.7-6.9) and in the ER negative patients it was 2.6 months (95% CI: 2.1-3-1). In the ER positive patients the median overall survival (OS) time was 13.3 months (95% CI: 7.7-18.9), in the ER negative patients the corresponding numbers were 6.1 months (95% CI: 4.1-8.2). Treatment with exemestane was well tolerated. Treatment of estrogen positive advanced or recurrent endometrial cancer with exemestane, an aromatase inhibitor, resulted in a response rate of 10% and lack of progression after 6 months in 35% of the patients.

The aim of this study is to evaluate the leisure time physical activity of Polish farmers in the context of meeting health-related recommendations, and to diagnose the social and economic determinants. The analysis concerned leisure and transportation activities of various intensity and sedentary time. Farmers (n=153) aged over 18 were selected from a representative sample of Polish society (n=2039). In order to evaluate LTPA, the long version of the IPAQ was used. Statistically significant differences between the variables were tested using non-parametric tests. The relationship between the amount of exercise recommended by the WHO and studied socio-demographic criteria was assessed using log-linear analysis. The WHO health recommendations were met by 33.3% of farmers. Shares in LTPA (19.1%) and transportation (19.2%) significantly increased the chance of achieving these norms (OR=12.54 and 0.07, respectively). Along with age (≥40 years) and income (≥3000 PLN/Є750) of Polish farmers, the risk of insufficient physical activity increased. Average MET-min/week for LTPA was 299.8±583.4 and transportation - 521.2±1973.9. The average time of sitting during working days was 4.4±2.9, while it was 4.5±3.2 hrs/day during weekends. Health-promoting changes are necessary among Polish farmers, including an increase in the awareness of health benefits and the necessity of undertaking physically active ways of spending leisure time. It seems to be a legitimate action to develop a mini-tourist trail in the rural environment as a means of promoting physical activity also among women aged over 40, and from lower income groups, who are especially threatened by inactivity.

To evaluate if the administration of intraperitoneal bupivacaine decreased postoperative pain in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery. Retrospective cohort study (Canadian Task Force classification II-3). University-based gynecologic oncology practice operating at a tertiary medical center. All patients on the gynecologic oncology service undergoing minimally invasive surgery between September 2011 and June 2013. Starting August 2012, intraperitoneal administration of .25% bupivacaine was added to all minimally invasive surgeries. These patients were compared with historical control subjects who had surgery between September 2011 and July 2012 but did not receive intraperitoneal bupivacaine. One-hundred thirty patients were included in the study. The patients who received intraperitoneal bupivacaine had lower median narcotic use on the day of surgery and the first postoperative day compared with those who did not receive intraperitoneal bupivacaine (day 0: 7.0 mg morphine equivalents vs 11.0 mg, p = .007; day 1: .3 mg vs 1.7 mg, p = .0002). The median patient-reported pain scores were lower on the day of surgery in the intraperitoneal bupivacaine group (2.7 vs 3.2, p = .05) CONCLUSIONS: The administration of intraperitoneal bupivacaine was associated with improved postoperative pain control in patients undergoing minimally invasive gynecologic and gynecologic cancer surgery and should be further evaluated in a prospective study.

Full Text Available Aim: To study the epidemiological profile, clinical symptoms and referral patterns of patients with gynecological malignancy. To evaluate pain symptoms, response to treatment and factors affecting management in patients with advanced gynecological malignancies. Methods: A retrospective analysis was performed of the gynecological malignancy cases registered at the Pain and Palliative Care Clinic, Calicut, over a 12-month period between January 2006 and December 2006.Patient characteristics, symptoms and response to treatment were evaluated in detail. Results: A total of 1813 patients registered, of which 64 had gynecological malignancies. Most of the cases were referred from the Oncology Department of the Calicut Medical College. Fifty-five percent of the patients were unaware of their diagnosis. Psychosocial issues and anxiety were observed in 48%. Insomnia was seen in 52% of the cases. Pain was the most common and most distressing symptom. Adequate pain relief was achieved in only 32% of the patients. Conclusions: The number of gynecological malignancy cases attending the Pain and Palliative Care Clinic is small. Pain is the most common and distressing symptom, with only 32% of the patients achieving adequate pain relief. Poor drug compliance, incomplete assessment of pain and the lack of awareness of morphine therapy were identified as the most common causes for poor pain control.

Small cell carcinoma (SmCC) of the female genital tract constitutes a diagnostic and clinical challenge given its rarity and the lack of standardized therapeutic approaches. Here we review the morphological, clinical and molecular features of gynecologic SmCCs and discuss potential areas for future research. Data for this review article were identified by searches of PubMed, EMBASE and the Internet using the search terms "small cell carcinoma" or "neuroendocrine carcinoma" and "gynecologic", "uterine cervix", "cervix", "uterus", "endometrium", "ovary", "vagina", "fallopian tube" or "vulva", and research articles published in English between 1972 and February 2014 were included. SmCCs arising from different organs within the gynecologic tract share the same histopathologic characteristics, which closely resemble those of small cell lung carcinoma. The expression of at least one immunohistochemical neuroendocrine marker is a common finding. The uterine cervix is the most frequent site of SmCC in the female genital tract. HPV infection seems to play a role in the development of cervical SmCC but not in cancers of other gynecologic sites. FIGO stage is an established prognostic factor, in particular in SCCs of the cervix. Irrespective of the site, SmCCs of the gynecologic tract display an aggressive clinical behavior with few reported long-term survivors. The therapeutic management includes surgery, radiotherapy and chemotherapy. Despite the potential differences in etiology and risk factors, SmCCs from different sites of the gynecologic tract have similar morphologic appearances and clinical behavior. Recent genomic analyses of small cell carcinoma of the lung have revealed potential driver genomic alterations. We posit that the comprehensive genomic characterization of gynecologic SmCCs may lead to the identification of markers that result in an improvement of diagnostic reproducibility of SmCCs of the gynecologic tract, and of molecular aberrations that may be

Celiac disease affects about 1% of the population. Since most Polish households have a broadband Internet connection, a lot of people use web resources to learn about health and disease. YouTube service (www.youtube.com) offers a lot of videos concerning celiac disease. However, the credibility of the Polish videos available on YouTube and concerning celiac disease has never been analyzed. The aim of the study was to determine whether the YouTube service offers valuable content for Polish people affected by celiac disease. One hundred and fifty-four unique videos devoted to celiac disease and available in the Polish language were identified and critically assessed. Each video was categorized due to its topic(s), and evaluated for its credibility by two independent researchers. In general, 127 (82.5%) videos were found to be credible. The most credible categories of content presented organizations and events related to celiac disease/celiac society, followed by culinary recipes (100.0, 100.0, and 95.6% of credible videos, respectively). The least trustworthy categories were devoted to pathobiology and advertisements (55.6 and 54.3% of credible videos, respectively). YouTube service can serve as a supplementary source of knowledge for people affected by celiac disease, after careful selection of trustworthy content.

Full Text Available Gynecological cancers are among the most common cancers in women and hence an important public health issue. Due to the lack of cancer awareness, variable pathology, and dearth of proper screening facilities in developing countries such as India, most women report at advanced stages, adversely affecting the prognosis and clinical outcomes. Ovarian cancer has emerged as one of the most common malignancies affecting women in India and has shown an increase in the incidence rates over the years. Although cervical cancer is on a declining trend, it remains the second most common cancer in women after breast cancer. Many researchers in India have published important data in the field of gynecologic oncology, covering all domains such as basic sciences, preventive oncology, pathology, radiological imaging, and clinical outcomes. This work has given us an insight into the in-depth understanding of these cancers as well as the demographics and survival rates in the Indian population. This aim of this review is to discuss the important studies done in India for all gynecological cancers.

Immunologic and radionuclide methods are used increasingly in diagnostics and therapy. This applies especially to problems of malignant diseases. Tumor localization diagnosis has gained much from immunoscintigraphy, a non-invasive method combining immunologic and nuclear medicine techniques. Activated monoclonal antibodies against tumorous antigens make it possible to show malignant tumors scintigraphically. An introduction is given to the technique as well as first results of applying immunoscintigraphy to gynecological oncology. (author)

Ireland, Luu Doan; Allen, Rebecca H

2016-02-01

Satisfactory pain control for women undergoing office gynecologic procedures is critical for both patient comfort and procedure success. Therefore, it is important for clinicians to be aware of the safety and efficacy of different pain control regimens. This article aimed to review the literature regarding pain control regimens for procedures such as endometrial biopsy, intrauterine device insertion, colposcopy and loop electrosurgical excisional procedure, uterine aspiration, and hysteroscopy. A search of published literature using PubMed was conducted using the following keywords: "pain" or "anesthesia." These terms were paired with the following keywords: "intrauterine device" or "IUD," "endometrial biopsy," "uterine aspiration" or "abortion," "colposcopy" or "loop electrosurgical excisional procedure" or "LEEP," "hysteroscopy" or "hysteroscopic sterilization." The search was conducted through July 2015. Articles were hand reviewed and selected by the authors for study quality. Meta-analyses and randomized controlled trials were prioritized. Although local anesthesia is commonly used for gynecologic procedures, a multimodal approach may be more effective including oral medication, a dedicated emotional support person, and visual or auditory distraction. Women who are nulliparous, are postmenopausal, have a history of dysmenorrhea, or suffer from anxiety are more likely to experience greater pain with gynecologic procedures. Evidence for some interventions exists; however, the interpretation of intervention comparisons is limited by the use of different regimens, pain measurement scales, patient populations, and procedure techniques. There are many options for pain management for office gynecologic procedures, and depending on the procedure, different modalities may work best. The importance of patient counseling and selection cannot be overstated.

Gynecological cancer survivors are at increased risk of psychological problems including suicide risk. Suicidal ideation, which was thought to be precursor to suicide attempts, has not been well studied. This study aimed to investigate the prevalence, and determinants of suicidal ideation for women with gynecological cancer, and then to assess the effect of coping style and social support on suicidal ideation. Patients with cervical, ovarian and endometrial cancers seen at Hunan Provincial Tumor Hospital from September 2012 to June 2013 were consecutively recruited and were asked to complete the Zung Self-Rating Depression Scale, Suicidal Ideation of Self-rating Scale, Medical Coping Modes Questionnaire and Social Support Rating Scale. Path analysis was used to examine the relationship among coping style, social support, depression symptoms and suicidal ideation. A total of 579 (579/623, 93.0%) gynecological cancer patients were enrolled in this study and completed all investigations between September 2012 and June 2013. Among them, 105 (18.1%) patients reported suicidal ideation, with the highest rate in patients with ovarian cancer (30.16%). Suicidal ideation was associated with depression symptoms, care providers, chemotherapy history and acceptance-resignation. Path analysis showed that the acceptance-resignation affected suicidal ideation directly as well as mediated by social support and depression symptoms, while confrontation and avoidance affected suicidal ideation entirely through social support and depression symptoms. Suicidal ideation is high among patients with gynecological cancer, especially among ovarian cancer patients. Coping strategies such as confrontation and avoidance, and social support may be helpful for preventing suicidal ideation among them. Copyright © 2015 John Wiley & Sons, Ltd.

To verify the feasibility of electroacupuncture analgesia applied to gynecologic outpatient operation. Two hundred patients were randomly divided into an electroacupuncture analgesia group and an intravenous anesthesia group, 100 cases in each group. Operation types included artificial abortion, diagnostic curettage and remove of intrauterine divice. The electroacupuncture analgesia group was treated with electroacupuncture at bilateral Hegu (LI 4) and Neiguan (PC 6), and the routine gynecologic outpatient operation was performed under patients' waking state. The intravenous anesthesia group was treated with routine gynecologic outpatient operation after intravenous injection of fentanyl and propofol. The excellent rate and the effective rate of analgesia were 88.0% (88/100) and 100.0% (100/100) in the electroacupuncture analgesia group, and 94.0% (94/100) and 100.0% (100/100) in the intravenous anesthesia group, with no statistically significant differences between the two groups (all P > 0.05). There was no adverse reaction in the electroacupuncture anesthesia group, but 11 cases of adverse reactions in the intravenous anesthesia group. Electroacupuncture analgesia can effectively alleviate the pain during gynecologic outpatient operation and it is simple and safe without adverse reactions.

Ostrzenski, Adam

2013-04-01

The objective of this article was to assist cosmetic-plastic surgeons in selecting aesthetic cosmetic gynecologic-plastic surgical interventions. Target methodological analyses of pertinent evidence-based scientific papers and anecdotal information linked to surgical techniques for cosmetic-plastic female external genitalia were examined. A search of the existing literature from 1900 through June 2011 was performed by utilizing electronic and manual databases. A total of 87 articles related to cosmetic-plastic gynecologic surgeries were identified in peer-review journals. Anecdotal information was identified in three sources (Barwijuk, Obstet Gynecol J 9(3):2178-2179, 2011; Benson, 5th annual congress on aesthetic vaginal surgery, Tucson, AZ, USA, November 14-15, 2010; Scheinberg, Obstet Gynecol J 9(3):2191, 2011). Among those articles on cosmetic-plastic gynecologic surgical technique that were reviewed, three articles met the criteria for evidence-based medicine level II, one article was level II-1 and two papers were level II-2. The remaining papers were classified as level III. The pertinent 25 papers met the inclusion criteria and were analyzed. There was no documentation on the safety and effectiveness of cosmetic-plastic gynecologic procedures in the scientific literature. All published surgical interventions are not suitable for a cosmetic-plastic practice. The absence of documentation on safety and effectiveness related to cosmetic-plastic gynecologic procedures prevents the establishment of a standard of practice. Traditional gynecologic surgical procedures cannot be labeled and used as cosmetic-plastic procedures, it is a deceptive practice. Obtaining legal trademarks on traditional gynecologic procedures and creating a business model that tries to control clinical-scientific knowledge dissemination is unethical. This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings

2013-11-01

Lower limb lymphedema (LLL) is a common condition after pelvic cancer treatment but few studies have evaluated its effect on the quality of life and its consequences on daily life activities among gynecological cancer survivors. We identified a cohort of 789 eligible women, treated with pelvic radiotherapy alone or as part of combined treatment of gynecological cancer, from 1991 to 2003 at two departments of gynecological oncology in Sweden. As a preparatory study, we conducted in-depth interviews with gynecological cancer survivors and constructed a study-specific questionnaire which we validated face-to-face. The questionnaire covered physical symptoms originating in the pelvis, demographic, psychological, and quality of life factors. In relation to the lymph system, 19 questions were asked. Six hundred sixteen (78 %) gynecological cancer survivors answered the questionnaire and participated in the study. Thirty-six percent (218/606) of the cancer survivors reported LLL. Overall quality of life was significantly lower among cancer survivors with LLL. They were also less satisfied with their sleep, more worried about recurrence of cancer, and more likely to interpret symptoms from the body as recurrence. Cancer survivors reported that LLL kept them from physical activity (45 %) and house work (29 %) and affected their ability to partake in social activities (27 %) or to meet friends (20 %). Lower limb lymphedema has a negative impact on quality of life among gynecological cancer survivors, affecting sleep and daily life activities, yet only a few seek professional help.

Promoting gynecologic cancer awareness at a critical juncture--where women and providers meet.

Given the absence of effective population-based screening tests for ovarian, uterine, vaginal, and vulvar cancers, early detection can depend on women and health care providers recognizing the potential significance of symptoms. In 2008, the Centers for Disease Control and Prevention's (CDC) Inside Knowledge campaign began distributing consumer education materials promoting awareness of gynecologic cancer symptoms. We investigated providers' in-office use of CDC gynecologic cancer materials and their recognition of the symptoms highlighted in the materials. We analyzed data from a national 2012 survey of US primary care physicians, nurse practitioners, and gynecologists (N = 1,380). Less than a quarter of providers (19.4%) reported using CDC gynecologic cancer education materials in their offices. The provider characteristics associated with the use of CDC materials were not consistent across specialties. However, recognition of symptoms associated with gynecologic cancers was consistently higher among providers who reported using CDC materials. The possibility that providers were educated about gynecologic cancer symptoms through the dissemination of materials intended for their patients is intriguing and warrants further investigation. Distributing consumer education materials in health care provider offices remains a priority for the Inside Knowledge campaign, as the setting where women and health care providers interact is one of the most crucial venues to promote awareness of gynecologic cancer symptoms.

Various grades of urological injuries occur following gynecological operations. Some are recognized during or after surgery but others pass unnoticed. To study the urological injuries that follow gynecological operations in our centre. Retrospective study. Nnamdi Azikiwe University Teaching Hospital, Nnewi Nigeria, a third generation tertiary institution serving rural, semi-urban, and urban communities. Searching through the records, all the gynecological operations performed in our centre from 1st July 1998 to 30th June 2003 were reviewed. Those patients in whom there were documented evidences of urological injuries were noted. Similarly, all the urological injuries treated in our institution during the same period but resulting from gynecological operations carried out in peripheral hospitals were also noted. From the relevant medical records, the following data were extracted: type of gynecological operation, nature of urological injury, time when injury was detected, status of the surgeon, management modalities, and outcome. A total of 37 urological injuries occurred but, because of incomplete records in five, only 32 patients were included in this study.

2015-01-01

During the financial crisis a notion that the Polish exchange rate is not determined effectively was very dominant, because of a contagion effect of the global financial crisis on the Polish economy. In addition, many foreign exchange market analysts explained developments in the Polish exchange market trough a hypothesis that the Polish zloty exchange rate follows other exchange rates. This contradicts market efficiency as this would lead to profitable arbitrage possibility based on past inf...

Symmetry or asymmetry? Cross-border openness of service providers in Polish-Czech and Polish-German border towns

2015-03-01

Full Text Available The symmetry and/or asymmetry in terms of cross-border openness of service providers is examined in this article, for the cases of two border twin towns: Cieszyn/Český Těšín at the Polish-Czech border, and Gubin/Guben at the Polish-German border. To assess the level of openness of firms towards clients from the other side of the border, four trans-border categories were examined: neighbour’s language visible at store location; business offers in the language of the neighbour; the possibilities of payment in the neighbour’s currency; and the staff’s knowledge of the language. This enabled a comparison of both parts of the particular twin towns in relation to the character of cross-border openness, as well as an assessment of their symmetry/asymmetry. Comparisons of Gubin/Guben and Cieszyn/Český Těšín with respect to the analysed features were also carried out. The analysis shows significant variation in the level of cross-border openness towards clients from neighbouring countries. Whereas in the Polish-Czech town a relative symmetry was observed, in the Polish-German case, significant asymmetry was noted.

Transformation of the Polish Banking Sector

Full Text Available In the post-war period the banking system in Poland underwent two important system transitions: after 1946 and after 1989. The third transformation began after May 1, 2004, but it did not have a systemic character. The Polish banking sector started to operate on the Single European Market. The first part of the paper is devoted to the problems of the banks transformations after 1989 with a special focus on the quantitative development of banks in 19892008, and on subsequent privatisation and consolidation processes. The former intensified in 19891999, and the latter in 19992002. The consolidation process was very noticeable in the sector of cooperative banks after 1994. The second part of the paper includes an economic and financial analysis of the banks. A lot of attention was paid to the liquidity of the banking sector. It was assessed as good, which was confirmed by a short-term rating of Moodys and by the Financial Stability Report 2009, published by the National Bank of Poland in June 2009. The comparison of the net profit of the banking sector in 19972008 shows its dependence on the economic situation and policy. The number of banks with capital adequacy ratio well above the minimum required by the banking supervision is rising. The financial power ratings are not favorable for the domestic banks. The third part of the paper focuses on the development directions of the Polish banking sector. It may be concluded on the basis of the analysis that privatisation and consolidation processes will be continued. They will concentrate on the capital of foreign banks already operating in Poland. As compared with individual foreign banks, the potential of the Polish banking sector is week. The fourth part of the paper focuses on the presentation Polish banking sector in the context of European Union banking sector. The paper finishes with conclusions. Generally, Polish banks have to implement a strategy to enable them to compete on the Single

This study evaluated the effect of different chairside polishing systems on the surface roughness and topography of monolithic zirconia. Thirty-five monolithic zirconia specimens (Lava PLUS, 3M ESPE) were fabricated and divided into five groups of seven and polished with the following: Group 1 (WZ)-Dura white stone followed by Shofu zirconia polishing kit; Group 2 (SZ)-Shofu zirconia polishing kit; Group 3 (CE)-Ceramiste porcelain polishers; Group 4 (CM)-Ceramaster porcelain polishers; and Group 5 (KZ)-Komet ZR zirconia polishers. All specimens were ground with a fine-grit diamond bur prior to polishing procedures to simulate clinical finishing. Baseline and post-polishing profilometric readings were recorded and delta Ra values (difference in mean surface roughness before and after polishing) were computed and analyzed using one-way analysis of variance and Scheffe post hoc test (pSEM) images of the ground but unpolished and polished specimens were acquired. Delta Ra values ranged from 0.146 for CE to 0.400 for KZ. Delta Ra values for KZ, WZ, and SZ were significantly greater than for CE. Significant differences in delta Ra values were also observed between KZ and CM. The SEM images obtained were consistent with the profilometric findings. Diamond-impregnated polishing systems were more effective than silica carbide-impregnated ones in reducing the surface roughness of ground monolithic zirconia.

Simulation and analysis of an alternative kinematics for improving the polishing uniformity over the surface of polished tiles

Directory of Open Access Journals (Sweden)

Weingaertner, W. L.

2010-10-01

Full Text Available The present work investigates the possibility of adopting a new kinematics at the industrial polishing lines of porcelain stoneware tile. An alternative motion of the transverse oscillation of the polishing heads is proposed, in which no radical changes in the industries facilities are required. The basic idea is to replace the purely sinus motion of the polishing heads by a rather trapezoid wavelike motion. In theory this could be achieved simply by adopting regular delays at the transverse oscillation motion. Consequences of this alternative kinematics were quantitatively analyzed considering the spatial homogeneity of polishing expected for tiles. Such homogeneity was represented by the coefficient of variation of the distribution of polishing time over the surface, which was in turn determined by means of computational simulations, taking into account the effect of multiple polishing heads.

El presente trabajo investiga la posibilidad de adoptar una nueva cinemática en las líneas de pulido industrial de baldosas de gres porcelánico. Se propone una propuesta alternativa de la oscilación transversal de los cabezales pulidores, en el que no hay cambios radicales en las instalaciones de las industrias son necesarias. La idea básica consiste en sustituir el movimiento totalmente del seno de los cabezales pulidores por un movimiento ondulatorio trapezoide. En teoría, esto podría lograrse sólo mediante la adopción de los habituales retrasos en el movimiento de oscilación transversal. las consecuencias de esta cinemática fueron analizados cuantitativamente, teniendo en cuenta la homogeneidad espacial de pulido. Tal homogeneidad fora representada por el coeficiente de variación de la distribución de lo tiempo de pulido en la superficie, determinada por medio de simulaciones computacionales, teniendo también en cuenta el efecto de pulido de las cabezas múltiples.

Cosmetic gynecology in the view of evidence-based medicine and ACOG recommendations: a review.

Science.gov (United States)

Ostrzenski, Adam

2011-09-01

To conduct a methodological review of the existing scientific literature within the field of cosmetic gynecology in the view of evidence-based medicine and to establish their relevance to the ACOG Committee Opinion No. 378. The appropriate medical subject heading terms were selected and applied in the search of the Internet multiple databases since 1900 until January 2010. Articles focusing on cosmetic gynecology were reviewed. Also, anecdotal and advertising literatures were analyzed. A methodological review of the literatures was conducted. In peer review journals, 72 relevant articles related to cosmetic gynecology were identified. Anecdotal information was identified in 3 sources and over 1,100 published marketing literatures were identified on the Internet and no scientific journals. Among reviewed articles on cosmetic gynecology, only two articles met the level II-2 in evidence-based medicine. The absence of documentations on the safety and effectiveness of cosmetic vaginal procedures in the scientific literatures was ACOG's main concern. Practicing cosmetic gynecology within ACOG recommendations is desirable and possible. Currently, the standard of practice of cosmetic gynecology cannot be determined due to the absence of the documentation on safety and effectiveness. Traditional gynecologic surgical procedures cannot be called cosmetic procedures, since it is a deceptive form of practice and marketing. Creating medical terminology trademarks and establishing a business model that tries to control clinical-scientific knowledge dissemination is unethical.

Single-port laparoscopy has gained popularity within minimally invasive gynecologic surgery for its feasibility, cosmetic outcomes, and safety. However, within gynecologic oncology, there are limited data regarding short-term adverse outcomes and long-term hernia risk in patients undergoing single-port laparoscopic surgery. The objective of the study was to describe short-term outcomes and hernia rates in patients after single-port laparoscopy in a gynecologic oncology practice. A retrospective, single-institution study was performed for patients who underwent single-port laparoscopy from 2009 to 2015. A univariate analysis was performed with χ 2 tests and Student t tests; Kaplan-Meier and Cox proportional hazards determined time to hernia development. A total of 898 patients underwent 908 surgeries with a median follow-up of 37.2 months. The mean age and body mass index were 55.7 years and 29.6 kg/m 2 , respectively. The majority were white (87.9%) and American Society of Anesthesiologists class II/III (95.5%). The majority of patients underwent surgery for adnexal masses (36.9%) and endometrial hyperplasia/cancer (37.3%). Most women underwent hysterectomy (62.7%) and removal of 1 or both fallopian tubes and/or ovaries (86%). Rate of adverse outcomes within 30 days, including reoperation (0.1%), intraoperative injury (1.4%), intensive care unit admission (0.4%), venous thromboembolism (0.3%), and blood transfusion, were low (0.8%). The rate of urinary tract infection was 2.8%; higher body mass index (P = .02), longer operative time (P = .02), smoking (P = .01), hysterectomy (P = .01), and cystoscopy (P = .02) increased the risk. The rate of incisional cellulitis was 3.5%. Increased estimated blood loss (P = .03) and endometrial cancer (P = .02) were independent predictors of incisional cellulitis. The rate for surgical readmissions was 3.4%; higher estimated blood loss (P = .03), longer operative time (P = .02), chemotherapy alone (P = .03), and

Results of the study were compared with some data reported by other WADA accredited anti-doping laboratories. Totally, 13 631 urine samples taken from Polish athletes of both sexes, aged 10-67 years, performing 46 disciplines of sport were tested. Cannabinoids were detected in 267 samples. Among Polish athletes the relative number of positive THC (tetrahydrocannabinol samples was one of the highest in Europe. The group of young Polish athletes (aged 16-24 years was the most THC-positive. THC-positive cases were noted more frequently in male athletes tested during out of competitions. The so-called contact sports (rugby, ice hockey, skating, boxing, badminton, body building and acrobatic sports were those sports, where the higher risk of cannabis use was observed. The legal interpretation of some positive cannabinoids results would be difficult because of some accidental and unintentional use of the narcotics by sportsmen. It was concluded that national anti-doping organizations (NADO’s, which are competent to judge whether the anti-doping rules were violated, should take into account the possibility of non-intentional doping use of cannabinoids via passive smoking of marijuana.

Composite adaptive control of belt polishing force for aero-engine blade

Science.gov (United States)

Zhsao, Pengbing; Shi, Yaoyao

2013-09-01

The existing methods for blade polishing mainly focus on robot polishing and manual grinding. Due to the difficulty in high-precision control of the polishing force, the blade surface precision is very low in robot polishing, in particular, quality of the inlet and exhaust edges can not satisfy the processing requirements. Manual grinding has low efficiency, high labor intensity and unstable processing quality, moreover, the polished surface is vulnerable to burn, and the surface precision and integrity are difficult to ensure. In order to further improve the profile accuracy and surface quality, a pneumatic flexible polishing force-exerting mechanism is designed and a dual-mode switching composite adaptive control(DSCAC) strategy is proposed, which combines Bang-Bang control and model reference adaptive control based on fuzzy neural network(MRACFNN) together. By the mode decision-making mechanism, Bang-Bang control is used to track the control command signal quickly when the actual polishing force is far away from the target value, and MRACFNN is utilized in smaller error ranges to improve the system robustness and control precision. Based on the mathematical model of the force-exerting mechanism, simulation analysis is implemented on DSCAC. Simulation results show that the output polishing force can better track the given signal. Finally, the blade polishing experiments are carried out on the designed polishing equipment. Experimental results show that DSCAC can effectively mitigate the influence of gas compressibility, valve dead-time effect, valve nonlinear flow, cylinder friction, measurement noise and other interference on the control precision of polishing force, which has high control precision, strong robustness, strong anti-interference ability and other advantages compared with MRACFNN. The proposed research achieves high-precision control of the polishing force, effectively improves the blade machining precision and surface consistency, and

To evaluate whether quality of peer review and reviewer recommendation differ based on reviewer subspecialty in obstetrics and gynecology and to determine the role of experience on reviewer recommendation. We performed a retrospective cohort study of reviews submitted to Obstetrics & Gynecology between January 2010 and December 2014. Subspecialties were determined based on classification terms selected by each reviewer and included all major obstetrics and gynecology subspecialties, general obstetrics and gynecology, and nonobstetrics and gynecology categories. Review quality (graded on a 5-point Likert scale by the journal's editors) and reviewer recommendation of "reject" were compared across subspecialties using χ, analysis of variance, and multivariate logistic regression. There were 20,027 reviews from 1,889 individual reviewers. Reviewers with family planning subspecialty provided higher-quality peer reviews compared with reviewers with gynecology only, reproductive endocrinology and infertility, gynecologic oncology, and general obstetrics and gynecology specialties (3.61±0.75 compared with 3.44±0.78, 3.42±0.72, 3.35±0.75, and 3.32±0.81, respectively, Ppeer reviews (greater than 195) compared with the lowest quintile (one to seven) (adjusted OR 2.85 [2.60-3.12]). Peer review quality differs based on obstetrics and gynecology subspecialty. Obstetrics and gynecology subspecialty and reviewer experience have implications for manuscript rejection recommendation. Reviewer assignment is pivotal to maintaining a rigorous manuscript selection process.

Factors influencing the surface quality of polished tool steels

Rebeggiani, S; Rosén, B-G

2014-01-01

Today’s demands on surface quality of moulds for injection moulding of plastic components involve no/low defect contents and roughness levels in the nm-range for high gloss applications. Material properties as well as operating conditions influence the mould finish, and thus the final surface of moulded products. This paper focuses on how particle content and different polishing strategies influence final surface qualities of moulds. Visual estimations of polished tool steel samples were combined with non-contact 3D-surface texture analysis in order to correlate traditional assessments to more quantitative methods, and to be able to analyse the surfaces at nanometre-level. It was found that steels with a lower proportion of particles, like carbides and oxides, gave rise to smoother polished surfaces. In a comparative study of polishers from different polishing shops, it was found that while different surface preparation strategies can lead to similar final roughness, similar preparation techniques can produce high-quality surfaces from different steel grades. However, the non-contact 3D-surface texture analysis showed that not all smooth polished surfaces have desirable functional topographies for injection moulding of glossy plastic components. (paper)

The aim of this study was to compare the efficacy and safety of enoxaparin and intermittent pneumatic compression (IPC) for venous thromboembolism (VTE) prevention in Japanese surgical patients with gynecologic malignancy. Patients ≥ 40 years old undergoing major surgery for gynecologic malignancy without preoperative VTE were included. Written informed consent was obtained. Enrolled patients received IPC immediately before surgery. After surgery, they were randomly assigned to either an enoxaparin group or an IPC-alone group. The enoxaparin group received enoxaparin injection (20 mg, subcutaneous, every 12 h) from postoperative day 2 to 8. IPC was discontinued after the first injection. In the IPC-alone group, IPC was continued until full ambulation. The primary end-point was incidence of VTE, including pulmonary embolism and deep vein thrombosis, regardless of symptoms. An interim analysis was to be conducted when the first 30 patients had completed the study protocol. A Data and Safety Monitoring Board was established for making recommendation on the continuation or termination of the study based on the interim results. At the time of the interim analysis, six cases of VTE were found: five in the IPC-alone group and one in the enoxaparin group (Fisher's exact test, P = 0.08). Three patients in the IPC-alone group developed pulmonary embolism, but none in the enoxaparin group did so (Fisher's exact test, P = 0.10). The study was terminated following the Data and Safety Monitoring Board's recommendation. Enoxaparin might have lowered the risk of VTE among surgical patients with gynecologic malignancy. Further studies are necessary to confirm this. © 2015 Japan Society of Obstetrics and Gynecology.

Stress is commonly encountered among cancer patients and may be a challenge affecting immune system resistance. Social support may contribute positively to the health of cancer patients, playing a role in coping with stress. The aim of this study was to determine whether ways of coping are related to social support given to women with gynecologic cancer. The study was performed as a cross-sectional design in a university hospital in Istanbul, Turkey, with 221 women with gynecologic cancer; the data were collected via 3 questionnaires, the first with sociodemographic and clinical features, the second with multidimensional scale of perceived social support, and the third with the scale of ways of coping with stress. Women with gynecologic cancer who were employed and declared their incomes as balanced and reported more years of education were more likely to perceive higher social support and to use the ineffective coping ways with stress at a lower rate (P perceived social support from family, friends, significant other, and total increases (P support from family members is the mainstay of coping with stress by women with gynecologic cancer. Nurses are indispensable in increasing social support required by women with gynecologic cancer. Well-trained clinical nurses via in-service programs should be experienced and aware of women diagnosed with gynecologic cancer in need of social support during hospital visits and provide necessary guidance.

Given the absence of effective population-based screening tests for ovarian, uterine, vaginal, and vulvar cancers, early detection can depend on women and health care providers recognizing the potential significance of symptoms. In 2008, the Centers for Disease Control and Prevention’s (CDC) Inside Knowledge campaign began distributing consumer education materials promoting awareness of gynecologic cancer symptoms. We investigated providers’ in-office use of CDC gynecologic cancer materials and their recognition of the symptoms highlighted in the materials. We analyzed data from a national 2012 survey of US primary care physicians, nurse practitioners, and gynecologists (N = 1,380). Less than a quarter of providers (19.4 %) reported using CDC gynecologic cancer education materials in their offices. The provider characteristics associated with the use of CDC materials were not consistent across specialties. However, recognition of symptoms associated with gynecologic cancers was consistently higher among providers who reported using CDC materials. The possibility that providers were educated about gynecologic cancer symptoms through the dissemination of materials intended for their patients is intriguing and warrants further investigation. Distributing consumer education materials in health care provider offices remains a priority for the Inside Knowledge campaign, as the setting where women and health care providers interact is one of the most crucial venues to promote awareness of gynecologic cancer symptoms.

In order to overcome classic polishing techniques, a novel hydrodynamic radial polishing tool (HyDRa) is presented; it is useful for the corrective lapping and fine polishing of diverse materials by means of a low-cost abrasive flux and a hydrostatic suspension system that avoids contact of the tool with the working surface. This tool enables the work on flat or curved surfaces of currently up to two and a half meters in diameter. It has the advantage of avoiding fallen edges during the polishing process as well as reducing tool wear out and deformation. The functioning principle is based on the generation of a high-velocity, high-pressure, abrasive emulsion flux with radial geometry. The polishing process is repeatable by means of the control of the tool operational parameters, achieving high degrees of precision and accuracy on optical and semiconductor surfaces, with removal rates of up to 9 mm3/hour and promising excellent surface polishing qualities. An additional advantage of this new tool is the possibility to perform interferometric measurements during the polishing process without the need of dismounting the working surface. A series of advantages of this method, numerical simulations and experimental results are described.

To compare 30-day postsurgical readmission rates and associated risk factors for readmission among women undergoing gynecologic surgery for benign and malignant conditions. In a retrospective cohort study, we identified patients after surgery for benign and malignant gynecologic conditions in the National Surgical Quality Improvement Program database between January 1, 2011, and December 31, 2012. Data collected included surgical factors, perioperative characteristics, surgical complications, and 30-day readmissions. The primary study outcome was readmission rates after gynecologic surgery for benign and oncologic conditions. Secondary study outcomes were risk factors associated with readmission among gynecologic surgeries performed for benign and oncologic conditions. Approximately 3% (1,444/46,718) compared with 8.2% (623/7,641) of patients who underwent gynecologic surgery for benign and malignant indications, respectively, were readmitted (P<.01). Compared with patients with benign surgical indications, those with uterine cancer (readmission rate 6.6%; odds ratio [OR] 2.21, 95% CI 1.95-2.51), ovarian cancer (readmission rate 10.9%; OR 3.82, 95% CI 3.29-4.45), and cervical cancer (readmission rate 10.1%; OR 3.51, 95% CI 2.71-4.53) were more likely to be readmitted. In multivariable models, independent risk factors for readmission for gynecologic cancer surgery included worse preoperative conditions (OR 1.49, 95% CI 1.17-1.90) and major complications (OR 17.84, 95% CI 14.19-22.43). In comparison, independent risk factors for readmission after surgery for benign indications included comorbid conditions (OR 1.36, 95% CI 1.18-1.57), operative time (15-59 minutes: referent; 60 minutes or greater: 1.37, 95% CI 1.14-1.63) and major complications (OR 53.91, 95% CI 46.98-61.85). Among gynecologic surgeries, those performed for oncologic indications were associated with readmission rates 2.8 times that of surgeries performed for benign indications. In adjusted models

1997-04-01

Longitudinal research indicates that approximately 50% of women treated for gynecologic cancer have sexual dysfunctions as they recover and become cancer survivors. This outcome occurs in the context of satisfactory quality of life in other domains. This study, comparing gynecologic cancer survivors (n = 61) and gynecologically healthy women (n = 74), documents the reliability of the latter observations with measures of quality of life (general, depressive symptoms, social contacts, and stress), sexual functioning, and health. Of added importance are analyses focused on variables that may predict risk for sexual morbidity. Specifically, sexual self-schema is tested as an important, sexually relevant individual difference. In regression analyses that controlled for estimates of precancer sexual behavior (intercourse frequency), extent of disease-treatment, and menopausal symptoms, sexual self-schema accounted for significant variance in predicting current sexual behavior and responsiveness.

We are developing high-energy grazing incidence shell optics for hard-x-ray telescopes. The resolution of a mirror shells depends on the quality of cylindrical mandrel from which they are being replicated. Mid-spatial-frequency axial figure error is a dominant contributor in the error budget of the mandrel. This paper presents our efforts to develop a deterministic cylindrical polishing process in order to keep the mid-spatial-frequency axial figure errors to a minimum. Simulation software is developed to model the residual surface figure errors of a mandrel due to the polishing process parameters and the tools used, as well as to compute the optical performance of the optics. The study carried out using the developed software was focused on establishing a relationship between the polishing process parameters and the mid-spatial-frequency error generation. The process parameters modeled are the speeds of the lap and the mandrel, the tool s influence function, the contour path (dwell) of the tools, their shape and the distribution of the tools on the polishing lap. Using the inputs from the mathematical model, a mandrel having conical approximated Wolter-1 geometry, has been polished on a newly developed computer-controlled cylindrical polishing machine. The preliminary results of a series of polishing experiments demonstrate a qualitative agreement with the developed model. We report our first experimental results and discuss plans for further improvements in the polishing process. The ability to simulate the polishing process is critical to optimize the polishing process, improve the mandrel quality and significantly reduce the cost of mandrel production

Generics have the potential to contain drug therapy costs; successful implementation of generic substitution policy largely depends on consumers' willingness to choose generics. This study aims to analyse the opinions, experiences and preferences of Polish patients towards generic medicines. The study was performed in Poland. The survey was conducted in June 2013 by means of face-to-face interviews. Respondents were drawn from the general population according to a population structure. The study covered a representative sample of 1,000 Poles; the results can be generalized to apply to the Polish population at large. Fifty-two percent of respondents declared to be more often choosing generics, twenty-three percent did not have any specific preferences, and twenty-five percent were more willing to choose brand-name medicines. Past experience with cheaper generic medicines, secondary or lower education, low income and residence in specific regions of Poland were all significantly associated with an increased willingness to choose generics. Respondents' attitudes towards generics were mostly influenced by the opinions of doctors and pharmacists. According to respondents, attitudes towards generics among doctors, pharmacists, family and friends, and in the mass media were mostly positive. There was no relationship between the preference of respondents for generics and factors such as their age, life stage, gender, household size or urban/rural locality. As a result of substituting a brand-name drug with its generic equivalent, 72 % of respondents reported that they had not noticed any difference in drug effectiveness; 21 % had experienced a reduced effectiveness of treatment or increased side effects at least once; and 7 % claimed the generic worked better. The majority of respondents who used cheaper substitutes claimed that generics represented good or very good quality. The study demonstrates that, when choosing medicines, Poles rely mainly on the opinions of their

2017-08-01

The use of channel-cut crystal monochromators has been traditionally limited to applications that can tolerate the rough surface quality from wet etching without polishing. We have previously presented and discussed the motivation for producing channel cut crystals with strain-free polished surfaces [1]. Afterwards, we have undertaken an effort to design and implement an automated machine for polishing channel-cut crystals. The initial effort led to inefficient results. Since then, we conceptualized, designed, and implemented a new version of the channel-cut polishing machine, now called C-CHiRP (Channel-Cut High Resolution Polisher), also known as CCPM V2.0. The new machine design no longer utilizes Figure-8 motion that mimics manual polishing. Instead, the polishing is achieved by a combination of rotary and linear functions of two coordinated motion systems. Here we present the new design of C-CHiRP, its capabilities and features. Multiple channel-cut crystals polished using the C-CHiRP have been deployed into several beamlines at the Advanced Photon Source (APS). We present the measurements of surface finish, flatness, as well as topography results obtained at 1-BM of APS, as compared with results typically achieved when polishing flat-surface monochromator crystals using conventional polishing processes. Limitations of the current machine design, capabilities and considerations for strain-free polishing of highly complex crystals are also discussed, together with an outlook for future developments and improvements.

The aim of this study was to evaluate the effects of various finishing and polishing systems on the final surface roughness of a resin composite. Hypotheses tested were: (1) reduced-step polishing systems are as effective as multiple-step systems on reducing the surface roughness of a resin composite and (2) the number of application steps in an F/P system has no effect on reducing surface roughness. Ninety discs of a nano-hybrid resin composite were fabricated and divided into nine groups (n = 10). Except the control, all of the specimens were roughened prior to be polished by: Enamel Plus Shiny, Venus Supra, One-gloss, Sof-Lex Wheels, Super-Snap, Enhance/PoGo, Clearfil Twist Dia, and rubber cups. The surface roughness was measured and the surfaces were examined under scanning electron microscope. Results were analyzed with analysis of variance and Holm-Sidak's multiple comparisons test (p One-gloss, Enamel Plus Shiny, and Venus Supra groups. (1) The number of application steps has no effect on the performance of F/P systems. (2) Reduced-step polishers used after a finisher can be preferable to multiple-step systems when used on nanohybrid resin composites. (3) The effect of F/P systems on surface roughness seems to be material-dependent rather than instrument- or system-dependent. Reduced-step systems used after a prepolisher can be an acceptable alternative to multiple-step systems on enhancing the surface smoothness of a nanohybrid composite; however, their effectiveness depends on the materials' properties.

To analyze sociocultural differences and perceptions of gynecological consultations for high school girls. A transversal study with 418 high school girls from three schools of different profiles in the city of Rio de Janeiro, Southeastern Brazil in 2010. A structured questionnaire encompassing socio-demographic characteristics, sexual behavior and evaluation of gynecological consultations was completed. Yates' Chi-square test and the Student's t-test were utilized adopting a value of p students of private and federal public schools presented similar profiles but both were different from the state school girls. The latter had lower socioeconomic status, and their parents had lower levels of education, the predominance of afro-descendants was observed, as were a larger number of sexual partners, pregnancy and cases of sexual violence. The average age of menarche and sexarche among the students were similar, but the first gynecological consultation was significantly later among the state school students. The majority showed some knowledge of contraception and STDs, although only a minority received guidance from the consultations. Students expressed the desire that the professionals dedicate more time, patience and availability to them during consultations. The provision of gynecological services for teenagers is not satisfactory, according to the teenagers' evaluations. Users of the private health system have gynecological consultations earlier than those who only have access to the public system. It is necessary to create mechanisms that facilitate access and adhesion to a routine of gynecological prevention for this age group.

Full Text Available Introduction: Health care to women is mainly focused on their gynecological and reproductive health. It is directed toward heterosexual women, their coital relations and the gestation, and doesn´t consider other practices and health issues. In recent years, lesbian women have become more visible in society, recalling that should not focus solely on sexual vaginal coitus and demanding their desire of being mothers.Objetives: With this study we try to be closer to lesbian women´s perceptions about their sexual and reproductive health, as well as trying to determine the factors that influence their health care and their relationship with the health system. Methodology: For this purpose was carried out a qualitative study among lesbian women of different ages. Techniques of collected data used were in-depth interview and discussion group. Results: The results show that lesbians feel safe at the risk of contracting sexually transmitted infections; in addition they express their difficulties to reveal their sexual identity to healthcare professionals as well as problems accessing maternity. Conclusions: We conclude with the idea of the need for greater diversity and sexual health training for professionals, as well as further research on gynecological, sexual and reproductive health of this group of population.

2003-01-01

This study evaluated the surface quality of four composite materials after polishing with six different polishing techniques. Eighty specimens were made using three packable composites (Definite/Degussa, SureFil/ Dentsply and Solitaire/Heraeus-Kulzer) and one hybrid composite (Herculite XRV/Kerr). Five specimens of each material were polished using flexible Sof-Lex discs. The remaining 75 specimens of each composite were prepared using three finishing protocols: a single 30 microm diamond (n = 25), two finishing diamonds (30/20 microm; n = 25) and a 30 microm diamond followed by a tungsten carbide finishing bur (n = 25). Final polishing of each of the three finishing groups was accomplished with SuperBuff, Diafix-oral, OneGloss, Astropol and HaWe Composite Polishers (n = 5, each). Surface roughness was evaluated quantitatively by laser-stylus profilometry. Average roughness (R(a)) was calculated; statistical analysis of the data was performed with two-way ANOVA and Scheffé post-hoc tests. The polished surfaces were examined qualitatively by SEM. The results showed significant effects on surface roughness from the different composites (p = 0.011) and polishing systems (p < 0.001). After polishing, the Solitaire surfaces (R(a) = 0.72 microm) were smoother than Definite (R(a) = 0.87 microm) and SureFil (R(a) = 0.89 microm) and significantly smoother than Herculite (R(a) = 0.92 microm; p = 0.011). Three of the polishing methods (SuperBuff, Diafix-oral and Astropol) achieved lower R(a)-values than Sof-Lex discs. The polishing quality of the one-step systems SuperBuff and Diafix-oral was strongly affected by the initial finishing protocol.

Study of Profile Changes during Mechanical Polishing using Relocation Profilometry

Kumaran, S. Chidambara; Shunmugam, M. S.

2017-10-01

Mechanical polishing is a finishing process practiced conventionally to enhance quality of surface. Surface finish is improved by mechanical cutting action of abrasive particles on work surface. Polishing is complex in nature and research efforts have been focused on understanding the polishing mechanism. Study of changes in profile is a useful method of understanding behavior of the polishing process. Such a study requires tracing same profile at regular process intervals, which is a tedious job. An innovative relocation technique is followed in the present work to study profile changes during mechanical polishing of austenitic stainless steel specimen. Using special locating fixture, micro-indentation mark and cross-correlation technique, the same profile is traced at certain process intervals. Comparison of different parameters of profiles shows the manner in which metal removal takes place in the polishing process. Mass removal during process estimated by the same relocation technique is checked with that obtained using weight measurement. The proposed approach can be extended to other micro/nano finishing processes and favorable process conditions can be identified.

Development of hybrid fluid jet/float polishing process

Science.gov (United States)

Beaucamp, Anthony T. H.; Namba, Yoshiharu; Freeman, Richard R.

2013-09-01

On one hand, the "float polishing" process consists of a tin lap having many concentric grooves, cut from a flat by single point diamond turning. This lap is rotated above a hydrostatic bearing spindle of high rigidity, damping and rotational accuracy. The optical surface thus floats above a thin layer of abrasive particles. But whilst surface texture can be smoothed to ~0.1nm rms (as measured by atomic force microscopy), this process can only be used on flat surfaces. On the other hand, the CNC "fluid jet polishing" process consists of pumping a mixture of water and abrasive particles to a converging nozzle, thus generating a polishing spot that can be moved along a tool path with tight track spacing. But whilst tool path feed can be moderated to ultra-precisely correct form error on freeform optical surfaces, surface finish improvement is generally limited to ~1.5nm rms (with fine abrasives). This paper reports on the development of a novel finishing method, that combines the advantages of "fluid jet polishing" (i.e. freeform corrective capability) with "float polishing" (i.e. super-smooth surface finish of 0.1nm rms or less). To come up with this new "hybrid" method, computational fluid dynamic modeling of both processes in COMSOL is being used to characterize abrasion conditions and adapt the process parameters of experimental fluid jet polishing equipment, including: (1) geometrical shape of nozzle, (2) position relative to the surface, (3) control of inlet pressure. This new process is aimed at finishing of next generation X-Ray / Gamma Ray focusing optics.

Acute abdominal pain related to the female genital organs is frequently encountered in the emergency department. Gynecological emergencies are diseases of the female reproductive system that are potentially life-threatening and peril the sexual function and fertility. In the diagnostic work-up of acute abdominal pain, a wide variety of differential diagnoses needs to be considered depending on the age of the patient and a concomitant pregnancy. There is significant clinical overlap with gastrointestinal emergencies. Therefore, imaging plays a key role in diagnosing the cause of the pain and the planning of the therapy. The aim of this review is to illustrate the significant role of imaging in frequently encountered gynecologic emergencies.

The Polish Country Study Project was initiated in 1992 as a result of the US Country Study Initiative whose objective was to grant the countries -- signatories of the United Nations` Framework Convention on Climate Change -- assistance that will allow them to fulfill their obligations in terms of greenhouse gases (GHG`s) inventory, preparation of strategies for the reduction of their emission, and adapting their economies to the changed climatic conditions. In February 1993, in reply to the offer from the United States Government, the Polish Government expressed interest in participation in this program. The Study proposal, prepared by the Ministry of Environmental Protection, Natural Resources and Forestry was presented to the US partner. The program proposal assumed implementation of sixteen elements of the study, encompassing elaboration of scenarios for the strategy of mission reduction in energy sector, industry, municipal management, road transport, forestry, and agriculture, as well as adaptations to be introduced in agriculture, forestry, water management, and coastal management. The entire concept was incorporated in macroeconomic strategy scenarios. A complementary element was the elaboration of a proposal for economic and legal instruments to implement the proposed strategies. An additional element was proposed, namely the preparation of a scenario of adapting the society to the expected climate changes.

2011-03-01

Stereotactic body radiotherapy (SBRT) is a novel form of noninvasive, highly conformal radiation treatment that delivers a high dose to tumor. The advantage of the technique resides in its ability to provide a high dose to tumor but spare normal tissues to an extent not previously possible. In this paper we will provide an introduction and review of this technology with regard to its use in gynecologic malignancies. Preliminary results from our experience are presented for the purpose of illustrating the range of SBRT applications in gynecologic oncology. A comprehensive literature review was conducted and our experience from the past three years was reviewed. Six case series are published that report results of SBRT for gynecologic malignancies. Sixteen gynecologic patients have been treated with SBRT at our institution. Treatment sites include pelvic and periaortic nodes (9 patients), oligometastatic disease (2), and cervical or endometrial primary tumors when other conventional external radiation or brachytherapy techniques were unsuitable (5). Preliminary follow-up at a median of 11 months (range, 0.3-33 months) demonstrates 79% locoregional control, 43% distant failure, and 50% overall survival. SBRT boosts to macroscopic periaortic node recurrences and other sites seem to provide local control and a possibility of long-term disease-free survival in carefully selected patients. Previously this had been difficult to achieve with conventional radiotherapy because of the proximity of periaortic nodes to small bowel. SBRT also offers a novel approach for minimally invasive treatment in the management of gynecological cancer where current surgical and radiotherapy techniques are unsuitable.

Full Text Available Residency training in obstetrics and gynecology is being challenged by increasingly stringent regulations and decreased operative experience. We sought to determine the perception of preparedness of incoming gynecologic oncology fellows for advanced surgical training in gynecologic oncology. An online survey was sent to gynecologic oncologists involved in fellowship training in the United States. They were asked to evaluate their most recent incoming clinical fellows in the domains of professionalism, level of independence/graduated responsibility, psychomotor ability, clinical evaluation and management, and academia and scholarship using a standard Likert-style scale. The response rate among attending physicians was 40% (n = 105/260 and 61% (n = 28/46 for program directors. Of those who participated, 49% reported that their incoming fellows could not independently perform a hysterectomy, 59% reported that they could not independently perform 30 min of a major procedure, 40% reported that they could not control bleeding, 40% reported that they could not recognize anatomy and tissue planes, and 58% reported that they could not dissect tissue planes. Fellows lacked an understanding of pathophysiology, treatment recommendations, and the ability to identify and treat critically ill patients. In the academic domain, respondents agreed that fellows were deficient in the areas of protocol design (54%, statistical analysis (54%, and manuscript writing (65%. These results suggest that general Ob/Gyn residency is ineffective in preparing fellows for advanced training in gynecologic oncology and should prompt a revision of the goals and objectives of resident education to correct these deficiencies.

For each topic, detection of sonographic pathologic features and sonographic mode are discussed, as well as the latest applications of sonodiagnostic methods, and relevant topics in clinical research. A new approach to evaluation of sonographic structures can be seen, including for borderline mucinous and serous ovarian tumors, in mean gray value, evaluation of grade of tissue echogenicity, evaluation of intact endometrial midline echo in ectopic pregnancy, and application of gel instillation sonography. Novel sonographic three-dimensional modalities, such as virtual navigation through three orthogonal planes, multislice tomosonography, volumetry by a virtual organ computer-aided analysis system, three-dimensional power Doppler, and space reconstruction of structures enable gynecologic diagnoses to be made more exactly. Clinical research investigates different sonographic features in benign and malignant gynecologic pathology. For studies of typical signs of benign uterine fibroids, endometrial volume, and vascularization of malignant endometrial tumors, as well as typical benign adnexal structures, the ovarian crescent sign were performed. At this time, no exact sonographic features for distinguishing between benign and malignant gynecologic tumors are available.Keywords: sonography, uterine cavity lesions, endometrial abnormalities, adnexal masses

Between the years of 2010-2012, it was estimated there were a total of 112,392 new cases of cancers in Thailand, thus, the total age-standardized rate (ASR) per 100,000 is 137.6. In regards to the most prevalent types of cancer in female, breast cancer has the highest ASR, followed by cervical cancer (ASR=14.4); liver and bile duct cancer; colon and rectum cancer; trachea, bronchus and lung cancer; ovarian cancer (ASR=6.0); thyroid cancer; non-Hodgkin lymphoma and uterine cancer (ASR=4.3). The trend of cervical cancer in Thailand is decreasing, one key factor in making this possible was the employment of dual tract strategy (Pap smear and visual inspection with acetic acid [VIA]) by the government in 2005. In the future, the government is also considering integrating human papillomavirus (HPV) vaccination into the national immunization program, which may assist in the prevention of cervical cancer. By studying the statistical data of gynecologic cancer, it will be possible to formulate measures for the prevention, control and treatment of gynecologic cancer. Eventually, it will potentially improve the quality of life (QoL) of patients as well as decrease the mortality rate caused by gynecologic cancer.

This note describes a simple and rapid method that we have used for obtaining a high degree of polish on spheres of ferrimagnetic materials. A high surface polish is of particular importance if one desires to perform ferrimagnetic resonance experiments on very narrow linewidth materials such as Yttrium Iron Garnet. It is not possible to obtain the very narrow linewidths without polishing the sample with a very fine abrasive such as 'Linde A'. Although the methods presently used for the fine polishing of ferrite spheres give satisfactory results, the method described here is of particular interest because of its simplicity and speed. For example with the air-jet tumbling technique it can take as long as three days of polishing to obtain an acceptable surface while our method will give the same results in one to two hours.

To determine the effect of finishing and polishing time on the surface gloss of various resin-composites before and after simulated toothbrushing. Eight representative resin-composites (Ceram X mono, Ceram X duo, Tetric EvoCeram, Venus Diamond, EsteliteSigma Quick, Esthet.X HD, Filtek Supreme XT and Spectrum TPH) were used to prepare 80 disc-shaped (12 mm x 2 mm) specimens. The two step system Venus Supra was used for polishing the specimens for 3 minutes (Group A) and 10 minutes (Group B). All specimens were subjected to 16,000 cycles of simulated toothbrushing. The surface gloss was measured after polishing and after brushing using the gloss meter. Results were evaluated using one way ANOVA, two ways ANOVA and Dennett's post hoc test (P = 0.05). Group B (10-minute polishing) resulted in higher gloss values (GV) for all specimens compared to Group A (3 minutes). Also Group B showed better gloss retention compared to Group A after simulated toothbrushing. In each group, there was a significant difference between the polished composite resins (P gloss after the simulated toothbrushing.

The entire research population was divided into three groups: Polish paralympians (n = 45, athletes with disabilities (n = 126 and non-athletes with disabilities (n = 47. The quality of sexual life of Polish paralympians was measured by using the Polish version of Female Sexual Function Index and International Index of Erectile Function. Clinically significant erectile dysfunctions were most often diagnosed in non-athletes (83.33% with 50% result of severe erectile dysfunctions, followed by athletes and paralympians with comparable results of 56.98% and 54.17% respectively (p = 0.00388. Statistically significant clinical sexual dysfunctions concerned lubrication, orgasm as well as pain domains, and prevailed among female non-athletes (68.42%, 68.42% and 57.89%. Practising sports at the highest level has a favourable effect on the sexuality of men and women with physical disabilities. Men with physical disabilities manifest more sexual disorders than women, an aspect which should be considered by health-care professionals working with people with disabilities.

The aim of the study was to estimate the use of hypoxen (antihypoxant) during the early postoperative course in gynecologic patients. The patients were divided into two groups according to the treatment scheme. 339 patients of the control group were under the routine therapy after the laparatomic gynecologic operations. 52 patients were additionally treated with hypoxen (antioxidant) (the main group). The impact of hypoxen on the antioxidant system and lipid peroxidation and its preventive effect on prolongation of the postoperative pain syndrom were estimated. The results of the study showed that hypoxen inhibited lipid peroxidation and activated the antioxidant system in the postoperative patients vs. the control group. It was also observed that among the patients additionally treated with hypoxen the percentage of those with prolonged postoperative pains was statistically lower (pgynecologic operations. The additional use of hypoxen in the routine therapy of the gynecologic patients prevented prolongation of the postoperative pain syndrom.

Traditional abrasive fluid jet polishing (FJP) is limited by its high-pressure equipment, unstable material removal rate, and applicability to ultra-smooth surfaces because of the evident air turbulence, fluid expansion, and a large polishing spot in high-pressure FJP. This paper presents a novel cavitation fluid jet polishing (CFJP) method and process based on FJP technology. It can implement high-efficiency polishing on small-scale surfaces in a low-pressure environment. CFJP uses the purposely designed polishing equipment with a sealed chamber, which can generate a cavitation effect in negative pressure environment. Moreover, the collapse of cavitation bubbles can spray out a high-energy microjet and shock wave to enhance the material removal. Its feasibility is verified through researching the flow behavior and the cavitation results of the negative pressure cavitation machining of pure water in reversing suction flow. The mechanism is analyzed through a computational fluid dynamics simulation. Thus, its cavitation and surface removal mechanisms in the vertical CFJP and inclined CFJP are studied. A series of polishing experiments on different materials and polishing parameters are conducted to validate its polishing performance compared with FJP. The maximum removal depth increases, and surface roughness gradually decreases with increasing negative outlet pressures. The surface becomes smooth with the increase of polishing time. The experimental results confirm that the CFJP process can realize a high material removal rate and smooth surface with low energy consumption in the low-pressure environment, together with compatible surface roughness to FJP.

Neuroendocrine neoplasms (NEN) of the female genital tract account for 2% of gynecological cancers. The aim of this study was to share our experience of 11 primary neuroendocrine neoplasms of the ovary. All patients who presented and/or were treated at our Institution with histologically-confirmed NEN of the ovary were included. Clinical data including tumor stage, diagnostic and therapeutic management and survival were assessed. Pathological specimens were critically reviewed. We identified 11 patients with NEN of the ovary consisting of nine neuroendocrine cancers and two carcinoids. Median age was 55.9 years. NEN were mostly poorly differentiated (72.4%). Primary surgery was performed in all patients. Adjuvant chemotherapy was administered in five patients consisting of platinum-based regimens. Median overall survival was 20 months. We propose a diagnostic algorithm for NEN of the ovary and discuss possible treatments according to FIGO stages. Patients should be included in multicenter studies whenever possible.

Full Text Available The aim of this paper is to present the socio-economic and spatial transformation of Polishcities after 1989. The Polish changes reached the structures of the three basic subsystems ofthe state: political (power, social (society, and economic (the economy. The systemictransformation that has taken place in Poland after 1989 is most readily visible in towns,although it was introduced in the country as a whole. For the development and transformationof towns, the most important were the introduction of local government structures andthe market model of the economy. The restitution of local government has ensured townsan authentic manager authorised to perform his function by the local community. The introductionof the market model to the economy has resulted in its privatisation and the appearanceof enterprise and competition. Towns, especially the biggest cities, have becomeattractive locations for investment. Cities with a balanced economic structure and well-developedinfrastructure had much better chances for growth to start with. Unfortunately, thetransformation period has also had some detrimental effects, the most important being unemploymentand all kinds of social deviance. However, Polish cities are certainly differenttoday and resemble Western cities to a greater extent than did the so-called socialist townsbuilt along theoretically beautiful but practically ineffectual ideological lines.

Impact of obesity on chemotherapy management and outcomes in women with gynecologic malignancies.

Science.gov (United States)

Horowitz, Neil S; Wright, Alexi A

2015-07-01

To describe the effects of obesity on the pharmacokinetics and dosing of chemotherapies and provide recommendations for chemotherapy management in obese women with gynecologic malignancies. PubMEd and MEDLINE databases were searched for articles published before June 2014. Only English-language articles were considered. 84 manuscripts were reviewed and 66 were included. Search terms included: obesity, overweight, body mass index, body surface area, glomerular filtration rate, chemotherapy, ovarian cancer, endometrial cancer, inflammation, and pharmacokinetics, Obese cancer patients have worse clinical outcomes, compared with non-obese patients. This may be because of differences in pharmacokinetics, metabolic dysregulation, or physicians' decisions to reduce chemotherapy dose-intensity during treatment to minimize toxicities. A 2012 American Society of Clinical Oncology Clinical Practice Guideline recommends using actual body weight for chemotherapy dosing in all patients treated with curative intent, irrespective of obesity, to avoid compromising clinical outcomes, including progression free survival (PFS) and overall survival (OS). In women with gynecologic cancers most studies demonstrate no difference in PFS or OS when obese patients receive the same chemotherapy dose intensity as non-obese patients, except perhaps with bevacizumab. Chemotherapy dose-intensity is a critical determinant of cancer outcomes and should be maintained in all patients, irrespective of obesity. Future studies should prospectively examine the impact of obesity on clinical outcomes (adverse events, survival) to improve the care of this growing population of patients who are at risk for inferior clinical outcomes.

2018-03-16

Limited information is available on how to polish and finish zirconia surfaces following computer-aided design/computer-aided manufacturing (CAD/CAM), specifically, how differing application forces and reuse of zirconia polishing systems affect zirconia topography. To determine the effect of differing, clinically relevant, polishing application forces and multiple usages of polishing burs on the surface topography of CAD/CAM zirconia. One hundred twenty 220-grit carbide finished zirconia disks were sintered according to manufacturer's directions and divided into two groups for the study of two coarse polishing bur types. Each group was divided into subgroups for polishing (15,000 rpm) at 15 seconds for 1.0 N, 4.5 N, or 11 N of force using a purpose-built fixture. Subgroups were further divided to study the effects of polishing for the first, fifth, 15th, and 30th bur use, simulating clinical procedures. Unpolished surfaces served as a control group. Surfaces were imaged with noncontact optical profilometry (OP) and atomic force microscopy (AFM) to measure average roughness values (Ra). Polishing burs were optically examined for wear. Scanning electron microscopy (SEM) was performed on burs and zirconia surfaces. One-way ANOVA with post hoc Tukey HSD (honest significant difference) tests (α=0.05) were used for statistical analyses. AFM and OP Ra values of all polished surfaces were significantly lower than those of the unpolished control. Different polishing forces and bur reuse showed no significant differences in AFM Ra. However, significant differences in OP Ra were found due to differing application forces and bur reuse between the first and subsequent uses. SEM and optical micrographs revealed notable bur wear, increasing with increasing reuse. SEM and AFM micrographs clearly showed polished, periodic zirconia surfaces. Nanoscale topography, as analyzed with kurtosis and average groove depth, was found dependent on the specific polishing bur type. These in

It is important to know what a young gynecologic oncologist perceives as a need to achieve a good training in gynecologic oncology. This study aims to evaluate the level of training in gynecologic oncology in Spain. A Web-based anonymous questionnaire was sent via e-mail to Spanish trainees listed in European Network of Young Gynecological Oncology (ENYGO). The survey was developed in four sections: (1) general training in gynecologic oncology, (2) distribution of current clinical activity, (3) surgical training, and (4) perspective future gynecologic oncology. It contained 51 questions, with multiple-choice answers that had to be answered by the ENYGO members. The questionnaire was sent to 64 people listed in the ENYGO database. Of these, 37 members responded (response rate of 58%). Overall, more training in surgery is necessary, to perform radical oncological surgeries. It is claimed a sub-specialty recognition, to ensure an equalitarian and homogeneous training.

You Zhaojin; Qian Shijun; Lu Ruiting

1995-11-01

The flow chart, resin performance and water quality specifications of the condensate polishing system for Qinshan Nuclear Power Plant (QNPP) are briefly described. The initial regeneration process and the following service of the condensate polishing system are introduced. And the ability to remove corrosion products and ionic impurities of the condensate polishing system are verified during start-up, normal power operation and condenser leakage of the plant. The result shows that the performance of condensate polishing system in QNPP can completely meet the design requirements. Especially during the start-up of the unit or the leakage of the condenser, despite the inlet water quality of the polishers is far worse than the specified standard, the outlet water quality is still controlled within the indexes. Finally, several existing problems, such as 'volume ratio between resins is not optimum' and 'the inert resin and anion resin can not be stratified completely', in the condensate polishing system are also discussed.

This study aimed to evaluate the influence of different polishing systems on the surface roughness of composite resins following procedures to simulate the effects of toothbrushing over time. Four currently available commercial composites were used to make 128 cylindrical specimens. The specimens were randomly allocated to polishing with a 1-step polisher or 1 of 3 multistep polishers (n = 8 per group). The baseline surface roughness was measured, and the specimens were submitted to 5000, 10,000, and 20,000 brushing cycles to represent toothbrushing throughout 6, 12, and 24 months, respectively. Results showed that surface roughness was influenced by the type of composite and polishing system and was not influenced by the simulated toothbrushing time. However, the surface roughness, as challenged by toothbrushing wear, was affected by the interaction among the composite, the polisher, and the toothbrushing time. The 1-step polisher produced the highest surface roughness and influenced toothbrushing wear resistance of some composites.

The purpose of this survey was to assess the opinions of members of the German Society of Gynecologic Endoscopy (AGE) regarding the laparoscopic treatment of ovarian malignancies and current practice at their institutions. Between February and October 2015, the AGE sent an anonymous online survey via mail to its members. The questionnaire solicited participants' opinions about the laparoscopic treatment of ovarian cancers according to T stage and borderline tumors, and information about current practice at their institutions. Participants were also asked their opinions on currently available data on this issue. Of 228 AGE members who completed the survey, 132 (58%) were fellows or attending physicians and 156 (68%) worked at university hospitals or tertiary referral centers. Most [212 (93%)] respondents stated that < 10% of all ovarian cancer cases were currently treated laparoscopically at their institutions. Most participants indicated that T1 (a, b, c) tumors [145 (64%)] and ovarian borderline tumors [206 (90%)], but not T2 [48 (21%)] or T3/4 [9 (4%) ovarian tumors] should or could be treated laparoscopically. One hundred seventy-two (75%) participants considered currently available data on this topic to be insufficient and 152 (66%) stated that they would take part in a clinical trial assessing a laparoscopic approach to T1/2 ovarian cancer. According to this survey, to the opinion of the majority of AGE members, laparoscopy might be a considerable option for the treatment of early ovarian malignancies and borderline tumors and should be evaluated further in future studies.

2012-03-01

To identify physical, psychological and social sexual concerns reported by gynecological (GYN) cancer survivors. A systematic review of the literature was conducted using CINAHL, PubMed and PsycInfo databases. Reference lists from articles provided additional relevant literature. Only research articles from peer-reviewed journals were included. A total of 37 articles were located; 34 explored women's sexual concerns following gynecological cancer diagnosis and treatment and 3 tested interventions for sexual concerns in women with gynecological cancer. Sexual concerns were identified across all dimensions of sexuality. Common concerns in the physical dimension were dyspareunia, changes in the vagina, and decreased sexual activity. In the psychological dimension, common concerns were decreased libido, alterations in body image, and anxiety related to sexual performance. And in the social dimension, common concerns were difficulty maintaining previous sexual roles, emotional distancing from the partner, and perceived change in the partner's level of sexual interest. Of the three psychoeducational intervention studies, two reported improvements in physical aspects of sexual function, and one reported improved knowledge, but without resolution of sexual concerns. Gynecological cancer survivors experience a broad range of sexual concerns after diagnosis and treatment, but the majority of studies emphasized physical aspects of sexuality, and may not adequately represent women's psychological and social sexual concerns. Health care providers should remain mindful of psychological and social sexual concerns when caring for gynecologic cancer survivors. Future research should systematically evaluate the full range of sexual concerns in large, representative samples of GYN cancer survivors and develop and test interventions to address those concerns.

2013-01-01

Full Text Available Abstract Background Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access. Methods We conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively. Results Survivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking. Conclusions Post-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.

Surface analysis of polished fused-silica laser lenses by ion-scattering spectrometry

International Nuclear Information System (INIS)

Orvek, K.; Steward, S.A.

1982-01-01

New advances in high-powered glass lasers, particularly the NOVA system, have resulted in a need for lenses having higher damage threshold values than those now available. It is currently thought that surface contaminants on the lenses are responsible for initiating part of the damage. These contaminants are apparently introduced during the final polishing stages. In this study, we used ion-scattering spectrometry (ISS) to identify contaminants arising through the use of different polishing techniques. Five lenses were studied, each having undergone different polishing procedures. The first lens was not polished after receiving it from the manfacturer (No. 381). Ion microprobe data were available for this lens, and they were compared to ISS results. The second lens had been polished with rouge, a polishing compound no longer in use (No. 796). This sample served as a further check on the ISS results. The third lens was studied as received from the manufacturer - with no handling or cleaning (No. 802). The final two lenses had both been polished using high-purity ceria, cerium oxide (No. 800 and No. 801). The difference between these two was that No. 800 was polished using a nylon lap, and No. 801 was polished using pitch as a lap. The 800-series lenses were all made from the same batch, and constituted the major part of the investigation

Ultrasound in gynecological cancer: is it time for re-evaluation of its uses?

Science.gov (United States)

Fischerova, Daniela; Cibula, David

2015-06-01

Ultrasound is the primary imaging modality in gynecological oncology. Over the last decade, there has been a massive technology development which led to a dramatic improvement in the quality ultrasound imaging. If performed by an experienced sonographer, ultrasound has an invaluable role in the primary diagnosis of gynecological cancer, in the assessment of tumor extent in the pelvis and abdominal cavity, in the evaluation of the treatment response, and in follow-up. Ultrasound is also a valuable procedure for monitoring patients treated with fertility-sparing surgery. Furthermore, it is an ideal technique to guide tru-cut biopsy for the collection of material for histology. Taking into consideration that besides its accuracy, the ultrasound is a commonly available, non-invasive, and inexpensive imaging method that can be carried out without any risk or discomfort to the patient; it is time to reconsider its role in gynecologic oncology and to allocate resources for a specialized education of future experts in ultrasound imaging in gynecology.

Using a well characterized 1.06 μm 150 ps glass laser pulse the damage characteristics for diamond turned, diamond turned/ polished, and polished copper and silver mirrors less than 5 cm diameter were studied. Although most samples were tested with a normal angle of incidence, some were tested at 45 0 with different linear polarization showing an increase in damage threshold for S polarization. Different damage mechanisms observed will be discussed. Laser damage is related to residual surface influences of the fabrication process. First attempts to polish diamond turned surfaces resulted in a significant decrease in laser damage threshold. The importance of including the heat of fusion in the one dimensional heat analysis of the theoretical damage threshold and how close the samples came to the theoretical damage threshold is discussed.

Spherical lenses lead to forming spherical aberration and reduced optical performance. Consequently, in practice optical system shall apply a combination of spherical lenses for aberration correction. Thus, the volume of the optical system increased. In modern optical systems, aspherical lenses have been widely used because of their high optical performance with less optical components. However, aspherical surfaces cannot be fabricated by traditional full aperture polishing process due to their varying curvature. Sub-aperture computer numerical control (CNC) polishing is adopted for aspherical surface fabrication in recent years. By using CNC polishing process, mid-spatial frequency (MSF) error is normally accompanied during this process. And the MSF surface texture of optics decreases the optical performance for high precision optical system, especially for short-wavelength applications. Based on a bonnet polishing CNC machine, this study focuses on the relationship between MSF surface texture and CNC polishing parameters, which include feed rate, head speed, track spacing and path direction. The power spectral density (PSD) analysis is used to judge the MSF level caused by those polishing parameters. The test results show that controlling the removal depth of single polishing path, through the feed rate, and without same direction polishing path for higher total removal depth can efficiently reduce the MSF error. To verify the optical polishing parameters, we divided a correction polishing process to several polishing runs with different direction polishing paths. Compare to one shot polishing run, multi-direction path polishing plan could produce better surface quality on the optics.

Objective: To determine sacroiliac joint compliance characteristics and pelvic floor movements in older women relative to gynecological surgery history and back pain complaints. Design: Single-visit laboratory measurement. Setting: University clinical research center. Participants: Twenty-five women aged 65 years or older. Outcome Measures: Sacroiliac joint compliance measured by Doppler imaging of vibrations and ultrasound measures of pelvic floor motion during the active straight leg raise test. Results: Doppler imaging of vibrations demonstrated test reliability ranging from 0.701 to 0.898 for detecting vibration on the ilium and sacrum sides of the sacroiliac joint. The presence of low-back pain or prior gynecological surgery was not significantly associated with a difference in the compliance or laxity symmetry of the sacroiliac joints. No significant difference in pelvic floor movement was found during the active straight leg raise test between subject groups. All P values were ≥.4159. Conclusions: Prior gynecological surgery and low-back pain were not significantly associated with side-to-side differences in the compliance of the sacroiliac joints or in significant changes in pelvic floor movement during a loading maneuver in a group of older women.

Clinical teaching at outpatient settings is an essential part of undergraduate medical students' training. The increasing number of students in many medical schools and short hospital stays makes inpatient teaching alone insufficient to provide students with the required clinical skills. To make up this shortfall, outpatient clinical teaching has been implemented by our Department of Obstetrics and Gynecology, King Khalid University, KSA, throughout the academic year 2015-2016. The aim of this study was to evaluate the impact of clinical teaching at outpatient settings on the academic performance of our students. In this comparative retrospective study, the effects of outpatient clinical teaching of obstetrics and gynecology on the academic performance of student was assessed through an objective structured clinical examination (OSCE). During their course on obstetrics and gynecology, 58 students had their clinical teaching both at inpatient and outpatient settings and constituted "study group". The remaining 52 students had clinical teaching only at inpatient settings and were considered "control group". Students in both groups sat for OSCE at the end of week 8 of the gynecology course. Students in both groups sat for OSCE at the end of week 8 of the gynecology course. Four stations were used for assessment: obstetric history, gynecological history, obstetric physical examination of pregnant women, and gynecological procedure station. Twenty marks were allocated for each station giving a total score of 80. The OSCE scores for study group were compared with those of the control group using Student's t -test; p performance in OSCE. There is evidence of remarkable improvement in the mastery of clinical skills as manifested in the students' scores in physical examination and procedures stations. These results will encourage us to have clinical teaching in other disciplines at outpatient settings.

Assess the clinical competence in Gynecology and obstetrics to the Internship students of the Faculty of Medicine, UNAM. The study design was descriptive, transverse type. We assessed 64 students, which had finished their gynecology field rotation with the objective structured clinical examination. The criteria to consider a competent performance level, was arbitrarily set up in 60%, both for individual problems and for the exam's global result. In 15 stations, the result was a 56.2 global average. The best performances were achieved in the following stations: take the pap smear (74.7), Pregnancy diagnostic (67.9), history of Gynecology and obstetrics (67.1), self examination of breast explanation (62.2) preclampsia (61.7) and cervicovaginitis (60). All the rest got a mark lower than 60. The results are lower than the ones obtained in written exams, because these cannot assess clinical skills. It could be observed that a student's performance in a clinical problem does not certainly predict his performance in other, so it seems to be determined more by the specific knowledge and the student's experience related to the case, than by a general problem-solving skill. The results show the advantages of this instrument to assess clinical skills, that justify its application in the formative process. This work evidences that its necessary to improve the acquisition of basic clinical skills trough systematic instructionals strategies and greater opportunities of learning.

Fourteen patients (11%) carried a BRCA mutations, and 22 (17%) carried another germline or acquired mutation, including multiple variants of uncertain significance. There was wide variation in surgical approach. Sixty-five patients (51%) underwent pelvic washings, and 43 (35%) underwent concurrent hysterectomy. Other concomitant procedures included midurethral sling placement, appendectomy, and hysteroscopy. Three patients experienced complications (transfusion, wound cellulitis, and vaginal cuff dehiscence). Thirteen patients (10%) had ovarian pathology detected on analysis of the surgical specimen, including metastatic tumor, serous cystadenomas, endometriomas, and Brenner tumor. Eight patients (6%) had Fallopian tube pathology, including 3 serous tubal intraepithelial cancers. Among the 44 uterine specimens, 1 endometrial adenocarcinoma and 1 multifocal endometrial intraepithelial neoplasia were noted. Regarding the entire study population, the number of patients meeting our study criteria and seen by gynecologic surgeons in the FPRN for oophorectomy increased by nearly 400% from 2013 to 2015. Since publication of the Suppression of Ovarian Function Trial data, bilateral oophorectomy has been recommended for some women with premenopausal breast cancer to facilitate breast cancer treatment with aromatase inhibitors. These women may be at elevated risk for occult abdominal pathology compared with the general population. Gynecologic surgeons

Pseudo-random tool paths for CNC sub-aperture polishing and other applications.

Science.gov (United States)

Dunn, Christina R; Walker, David D

2008-11-10

In this paper we first contrast classical and CNC polishing techniques in regard to the repetitiveness of the machine motions. We then present a pseudo-random tool path for use with CNC sub-aperture polishing techniques and report polishing results from equivalent random and raster tool-paths. The random tool-path used - the unicursal random tool-path - employs a random seed to generate a pattern which never crosses itself. Because of this property, this tool-path is directly compatible with dwell time maps for corrective polishing. The tool-path can be used to polish any continuous area of any boundary shape, including surfaces with interior perforations.

Objective: To analyze the impact of pathology review in gynecological malignancies. Materials and Methods: A retrospective chart review of all new gynecological patients seen between Dec. 2, 1993 and Jan. 4, 1996 was conducted to determine if a pathological review by the Institute's consultant pathologist altered the diagnosis, and if so whether the alteration changed patient management. A total of 528 patients were seen of which 124 had cervix cancer, 235 had endometrial cancer, 122 had a primary ovarian or peritoneal malignancy, 9 had a vaginal malignancy, 28 had vulvar cancer and 10 had a miscellaneous gynecological malignancy. Results: On pathology review the initial diagnosis was changed in 199 patients. This altered management of 63 patients. For patients with cervical cancer, the grade of tumor was the main alteration in pathological diagnosis, with occasional change in the presence of lymph vascular invasion. These did not translate into patient management changes. The occasional change in depth of invasion altered management in one patient. For endometrial primaries the changes in pathological diagnosis included grade, depth of invasion, and the presence of cervical involvement. This did change management in some cases. For the ovarian malignancies the main changes were grade, extent of disease or variation in histology, some of which resulted in changes in management. One patient with a vaginal lesion had the diagnosis changed which did change management. Of the patients diagnosed with vulvar cancer the pathological diagnosis changed in 8 patients. This included changes in grade and depth of invasion. This altered patient management in 2 patients. The remaining miscellaneous gynecological malignancies had only two diagnosis alterations which did alter management. Conclusion: Pathological reviews of gynecological malignancies are justified as it can alter patient management. In addition, the process facilitates the cooperation of the multidisciplinary team

Climate change is one of the key environmental, social and economical issues, and it is also followed by political consequences. Impact of climate conditions on countries' economy is increasingly recognized, and a lot of attention is given, both in the global scale and by the individual national governments. In years 2008-2010, at the Poland -Institute of Meteorology and Water Management-National Research Institute was realized the KLIMAT Project on Impact of climate change on environment, economy and society (changes, effects and methods of reducing them, conclusions for science, engineering practice and economic planning) No. POIG01-03-01-14-011/08. The project was financed by the European Union and Polish state budget in frame of Innovative Economy Operational Programme. A very wide range of research was carried out in the different thematic areas. One of them was "Natural disasters and internal safety of the country (civil and economical)." The problem of drought in Poland was developed in terms of meteorology and hydrology. "Proxy" Data Descriptions very often inform about dry years and seasons, hot periods without precipitation. Analysis of historical material allowed to extract the years that have experienced prolonged periods of high temperatures and rainfall shortages. Weather phenomenon defined as drought belongs to extreme events. This information was very helpful in the process of indexing and thus to restore the course and intensity of climatic elements in the past. The analysis covered the period from year 1000 to modern times. Due to the limited information from the period of 1000-1500 the authors focused primarily on the period from 1500 to 2010. Analysis of the collected material has allowed the development of a highly precise temporal structure of the possible occurrence of dry periods to Polish territory.

Murali, Rajmohan; Grisham, Rachel N; Soslow, Robert A

2018-01-01

The role of the pathologist in the multidisciplinary management of women with gynecologic cancer has evolved substantially over the past decade. Pathologists' evaluation of parameters such as pathologic stage, histologic subtype, grade and microsatellite instability, and their identification of patients at risk for Lynch syndrome have become essential components of diagnosis, prognostic assessment and determination of optimal treatment of affected women. Despite the use of multimodality treatment and combination cytotoxic chemotherapy, the prognosis of women with advanced-stage gynecologic cancer is often poor. Therefore, expanding the arsenal of available systemic therapies with targeted therapeutic agents is appealing. Anti-angiogenic therapies, immunotherapy and poly ADP ribose polymerase (PARP) inhibitors are now routinely used for the treatment of advanced gynecologic cancer, and many more are under investigation. Pathologists remain important in the clinical management of patients with targeted therapy, by identifying potentially targetable tumors on the basis of their pathologic phenotype, by assessing biomarkers that are predictive of response to targeted therapy (e.g. microsatellite instability, PD1/PDL1 expression), and by monitoring treatment response and resistance. Pathologists are also vital to research efforts exploring novel targeted therapies by identifying homogenous subsets of tumors for more reliable and meaningful analyses, and by confirming expression in tumor tissues of novel targets identified in genomic, epigenetic or other screening studies. In the era of precision gynecologic oncology, the roles of pathologists in the discovery, development and implementation of targeted therapeutic strategies remain as central as they are for traditional (surgery-chemotherapy-radiotherapy) management of women with gynecologic cancers.

Diabetes mellitus, the prevalence of which has increased dramatically worldwide, may put patients at a higher risk of cancer. The aim of our study is the clarification of the possible mechanisms linking diabetes mellitus and gynecological cancer and their epidemiological relationship. This is a narrative review of the current literature, following a search on MEDLINE and the Cochrane Library, from their inception until January 2012. Articles investigating gynecologic cancer (endometrial, ovarian, and breast) incidence in diabetic patients were extracted. The strong evidence for a positive association between diabetes mellitus and the risk for cancer indicates that energy intake in excess to energy expenditure, or the sequelae thereof, is involved in gynecological carcinogenesis. This risk may be further heightened by glucose which can directly promote the production of tumor cells by functioning as a source of energy. Insulin resistance accompanied by secondary hyperinsulinemia is hypothezised to have a mitogenic effect. Steroid hormones are in addition potent regulators of the balance between cellular differentiation, proliferation, and apoptosis. Inflammatory pathways may also be implicated, as a correlation seems to exist between diabetes mellitus and breast or endometrial carcinoma pathogenesis, although an analogous correlation with ovarian carcinoma is still under investigation. Antidiabetic agents have been correlated with elevated cancer risk, while metformin seems to lower the risk. Diabetes mellitus is associated with an elevation in gynecologic cancer risk. Moreover, there are many studies exploring the prognosis of patients with diabetes and gynecological cancer, the outcome and the overall survival in well-regulated patients.

Antimicrobial agents are widely used in gynecologic inflammation and surgical period, so as to cure some infectious diseases, reduce the chance of surgical incision infection, but at the same time, there are many adverse reactions. The use of nursing interventions in obstetrics and gynecology can significantly reduce the adverse drug reactions in the treatment. The results showed that the incidence of adverse reactions in the observation group was 8.8%, while that in the control group was 15.6%. The incidence of adverse reactions in the observation group was significantly lower than that in the control group (P<0.05). The results showed that the nursing intervention in obstetrics and gynecology could reduce the adverse drug reactions. In a word, the nursing intervention of obstetrics and gynecology can greatly reduce the adverse reaction of antibiotics and has certain application value. It is worth popularizing in clinical practice.

Results of prospective randomized comparative research of 2 total hemoglobin estimation methods are presented. There were laboratory tests and continuous noninvasive technique with multiwave spectrophotometry on the Masimo Rainbow SET. Research was carried out in two stages. At the 1st stage (gynecology)--67 patients were included and in second stage (obstetrics)--44 patients during and after Cesarean section. The standard deviation of noninvasive total hemoglobin estimation from absolute values (invasive) was 7.2 and 4.1%, an standard deviation in a sample--5.2 and 2.7 % in gynecologic operations and surgical delivery respectively, that confirms lack of reliable indicators differences. The method of continuous noninvasive total hemoglobin estimation with multiwave spectrophotometry on the Masimo Rainbow SET technology can be recommended for use in obstetrics and gynecology.

Concern that patients will react negatively to the idea of palliative care is cited as a barrier to timely referral. Strategies to successfully introduce specialty palliative care to patients have not been well described. We sought to understand how gynecologic oncologists introduce outpatient specialty palliative care. We conducted a national qualitative interview study at six geographically diverse academic cancer centers with well-established palliative care clinics between September 2015 and March 2016. Thirty-four gynecologic oncologists participated in semistructured telephone interviews focusing on attitudes, experiences, and practices related to outpatient palliative care. A multidisciplinary team analyzed interview transcripts using constant comparative methods to inductively develop and refine a coding framework. This analysis focuses on practices for introducing palliative care. Mean participant age was 47 years (standard deviation, 10 years). Mean interview length was 25 minutes (standard deviation, 7 minutes). Gynecologic oncologists described the following three main strategies for introducing outpatient specialty palliative care: focus initial palliative care referral on symptom management to dissociate palliative care from end-of-life care and facilitate early relationship building with palliative care clinicians; use a strong physician-patient relationship and patient trust to increase acceptance of referral; and explain and normalize palliative care referral to address negative associations and decrease patient fear of abandonment. These strategies aim to decrease negative patient associations and encourage acceptance of early referral to palliative care specialists. Gynecologic oncologists have developed strategies for introducing palliative care services to alleviate patient concerns. These strategies provide groundwork for developing system-wide best practice approaches to the presentation of palliative care referral.

Full Text Available The article studies the position of the Polish language in the multilingual space of the European Union and determines the key factors which facilitate its gaining popularity and spreading in Europe. A large territory and population determine the significant presence of Polish in the European Union. Intense economic development facilitates popularization of learning and using Polish in the business medium, however, English was and still remains the dominating language of business. Active work of the state on improving the reputation of the country abroad, civilizational (value­based unity with other nations of the EU, favorable geographical position, common Indo­European roots of Germanic, Romanic and Slavonic  languages as well as usage of the Latin type create favorable conditions for the development and popularization of Polish on the territory of the EU. The article also mentions a number of concerns, which are rooted in the historical past of a dependent or semi­dependent existence of the Polish people, namely, the existence of the Polish and culture in the shade of German and Russian culture space, the negative international image of modern Poland, which was formed at the beginning of the 1990­s, the low level of Europeans’ familiarization with the Polish culture, absence of popularity and economic necessity of learning Polish abroad.

MR angiography provides a new noninvasive method for evaluating vascular occlusive disease of the lower extremities and the branches of abdominal aorta. To our knowledge, no determinant of efficacy of MR angiography and images of gynecological diseases have yet been made. Maximum intensity projection image was obtained from the data set by the three dimensional contrast enhanced MR angiography (3D-CE MRA) with newly designed fat suppression method. MR angiogram reveals well visualization of lower abdominal aorta and its branches. Furthermore, uterine arteries were identified in 49.3% of the cases, branching from the internal iliac artery. Leiomyoma of the uterus showed an enhanced uterus in 53.7% of the eases. All cases of endometriosis demonstrated a homogeneous, high signal intensity being a specific finding. In conclusion, maximum intensity projection image of pelvis showed a good visualization of the lower abdominal aorta and its branches. Uterine artery and, in a few cases, ovarian artery can be demonstrated on MR angiography. All cases of endometriosis showed a significant, high signal intensity. This technique is noninvasive and be a supplementary method for diagnosis and follow up of vasculature of gynecological disorders. (author)

The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1,073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.This guideline was developed through a collaboration between the American Cancer Society and the American Society of Clinical Oncology and has been published jointly by invitation and consent in both CA: A Cancer Journal for

Nail polishes are cosmetic paints that may be susceptible of forensic analysis offering useful information to assist in a crime reconstruction. Although the nail polish appearance could allow a quick visual identification of the sample, this analysis is subjected to the perception and subjective interpretation of the forensic examiner. The chemical analysis of the nail polishes offers great deal of information not subjected to analyst interpretation. Confocal Raman spectroscopy is a well-suited technique for the analysis of paints due to its non-invasive and non-destructive nature and its ability to supply information about the organic and inorganic components of the sample. In this work, 77 regular and gel nail polishes were analyzed with confocal Raman spectroscopy using two laser wavelengths (532 and 780 nm). The sample behavior under the two laser wavelengths and the differences in the spectra taken at different points of the sample were studied for each nail polish. Additionally, the spectra obtained for all the nail polishes were visually compared. The results concluded that the longer laser wavelength prevents sample burning and fluorescence effects; the similarity among the spectra collected within the sample is not directly related with the presence of glitter particles; and 64% of the samples analyzed showed a characteristic spectrum. Additionally, the use of confocal Raman spectroscopy for the forensic analysis of nail polishes evidence in the form of flakes or smudges on different surfaces were studied. The results showed that both types of evidence can be analyzed by the technique. Also, two non-invasive sampling methods for the collection of the evidence from the nails of the suspect or the victim were proposed: (i) to use acetone-soaked cotton swabs to remove the nail varnishes and (ii) to scrape the nail polish from the nail with a blade. Both approaches, each exhibiting advantages and drawbacks in terms of transport and handling were appropriate

Clinical outcomes research in gynecologic oncology.

Clinical outcomes research seeks to understand the real-world manifestations of clinical care. In particular, outcomes research seeks to reveal the effects of pharmaceutical, procedural, and structural aspects of healthcare on patient outcomes, including mortality, disease control, toxicity, cost, and quality of life. Although outcomes research can utilize interventional study designs, insightful use of observational data is a defining feature of this field. Many questions in gynecologic oncology are not amenable to investigation in randomized clinical trials due to cost, feasibility, or ethical concerns. When a randomized trial is not practical or has not yet been conducted, well-designed observational studies have the potential to provide the best available evidence about the effects of clinical care. Such studies may use surveys, medical records, disease registries, and a variety of administrative data sources. Even when a randomized trial has been conducted, observational studies can be used to estimate the real-world effect of an intervention, which may differ from the results obtained in the controlled setting of a clinical trial. This article reviews the goals, methodologies, data sources, and limitations of clinical outcomes research, with a focus on gynecologic oncology. Copyright © 2017. Published by Elsevier Inc.

Novel ceria-polymer microcomposites for chemical mechanical polishing

Coutinho, Cecil A.; Mudhivarthi, Subrahmanya R.; Kumar, Ashok; Gupta, Vinay K.

2008-01-01

Abrasive particles are key components in slurries for chemical mechanical polishing (CMP). Since the particle characteristics determine surface quality of wafers during polishing, in this research, novel abrasive composite particles have been developed. These composite particles contain nanoparticles of ceria dispersed within cross-linked, polymeric microspheres such that the average mass fraction of ceria is approximately 50% in the particles. The microspheres are formed by co-polymerization of N-isopropylacrylamide (NIPAM) with 3-(trimethoxysilyl)propyl methacrylate (MPS) and contain interpenetrating (IP) chains of poly(acrylic acid) (PAAc). Infrared spectroscopy, dynamic light scattering, and transmission electron microscopy are employed to characterize the composite particles. Planarization of silicon dioxide wafers is studied on a bench-top CMP tester and the polished surfaces are characterized by ellipsometry, atomic force and optical microscopy. Slurries formed from the composite ceria-polymer particles lead to lower topographical variations and surface roughness than slurries of only ceria nanoparticles even though both slurries achieve similar removal rates of ∼100 nm/min for similar ceria content. Polishing with the novel composite particles gives surfaces devoid of scratches and particle deposition, which makes these particles suitable for the next generation slurries in CMP

Members of the Society of Gynecologic Oncology (SGO were surveyed electronically regarding consistency of counseling patterns of contraception and fertility concerns, most and least common contraceptive methods utilized, referral patterns, and incidence of unplanned pregnancy. Of the 1424 SGO members identified, 261 participated in the questionnaire, yielding a response rate of 18%. Eighty-two percent of respondents agreed unplanned pregnancy is a potential problem, but only 57% believed their patients understood unplanned pregnancy is possible during treatment. Half of respondents report “always” in terms of frequency that contraception is addressed among their high-risk patients. After adjustment for gender, we found that the odds of reporting providing fertility counseling were nearly three times higher among attendings as compared to fellows [AOR = 2.72; 95% CI = (1.44, 5.12, three times higher in women as compared to men [AOR = 2.80; 95% CI = (1.46, 5.38], as well as in individuals 50+ years as compared to those <40 years old [AOR = 4.91; 95% CI = (2.05, 11.74]. Ninety-six percent reported <5 unplanned pregnancies, to their knowledge, in the previous five years of clinical practice. Most providers acknowledge that unplanned pregnancy is a potential risk in fertile gynecologic oncology patients, but only half believe their patients understand an unplanned pregnancy is possible. An opportunity exists to provide more directed counseling regarding fertility during and after cancer therapy, and to educate patients and providers regarding more reliable, long acting contraceptive methods.

To determine the effect of abdominal and/or pelvic irradiation for gynecological malignancies on the later development of hyperthyroidism, 1,884 medical records of the patients diagnoses as carcinomas of cervix and corpus uteri, and of ovary were reviewed. Among 1,269 patients with radiation therapy, 5 patients developed hyperthyroidism after irradiation to the abdomen and/or pelvis. This is a statistically significant increase when compared with an epidemiological study. Radiation dose to the thyroid was estimated to be 30 to 200 rads. Two other patients who were irradiated to the nose or supraclavicular region in addition to the abdomen also developed hyperthyroidism. However, none of 581 patients without radiation therapy became hyperthyroid. The results indicate that radiation therapy for treatment of gynecological malignancy gives a significant radiation exposure with an increase in the incidence of subsequent hyperthyroidism

Delayed treatment of the massive bleeding in gynecologic and obstetric conditions can cause high morbidity and mortality. The aim of this study is to assess the angiographic findings and outcomes of transarterial embolization in cases of massive hemorrhage from underlying gynecological and obstetrical conditions. This is a retrospective study of 18 consecutive patients who underwent transarterial embolization of uterine and/or hypogastric arteries due to massive bleeding from gynecological and obstetrical causes from January 2006 to December 2011. The underlying causes of bleeding, angiographic findings, technical success rates, clinical success rates, and complications were evaluated. Massive gynecological and obstetrical bleeding occurred in 12 cases and 6 cases, respectively. Gestational trophoblastic disease was the most common cause of gynecological bleeding. The most common cause of obstetrical hemorrhage was primary post-partum hemorrhage. Tumor stain was the most frequent angiographic finding (11 cases) in the gynecological bleeding group. The most common angiographic findings in obstetrical patients were extravasation (2 cases) and pseudoaneurysm (2 cases). Technical and final clinical success rates were found in all 18 cases and 16 cases. Collateral arterial supply, severe metritis, and unidentified cervical laceration were causes of uncontrolled bleeding. Only minor complications occurred, which included pelvic pain and groin hematoma. Percutaneous transarterial embolization is a highly effective and safe treatment to control massive bleeding in gynecologic and obstetric emergencies.

Salvatore Settineri

2015-09-01

Full Text Available Background. The literature shows that women with gynecological problems have psychosomatic alteration in the body image perception and sexual distress. To our knowledge, these issues have so far been analyzed separately and rarely through a projective methods. Aim. The aim of this study is to analyze the role of body image and its relative weakness in gynecological pathology, through the Rorschach projective method. Method. The observation group consists of 66 women with an average age of 49 ± 17 year, belonging to the clinic of the University Hospital Vulvologia and Colpocitologia "Gaetano Martino" of Messina. For the evalutation was used Rorschach, according to the clinical method, in order to explore the representations of the subject's inner world. Results. The responses to the Rorschach cards show a prevalence of anatomical and sexual content, devitalized animals and object, in particular to the table VI. We observed in women a complex regarding generativity that reveals a fragmentation of body image representation and of the sexual imaginative function of the inner world. Conclusions. The sexual suffering in gynecology is a dimension that influences the symptomathology in the extent to which the psychological aspects profoundly affect bodily perceptions, weakening the self-image and altering the course of the disease.   Keywords: body image, sexuality, Rorschach, psychosomatic gynecology.

No consensus exists regarding the role of radiotherapy in the management of gynecologic cancer in nonagenarian patients. We retrospectively reviewed the outcomes of 19 consecutive nonagenarian patients with gynecologic cancer (6 endometrial cancers, 6 cervical cancers, 4 vulvar cancers, and 3 vaginal cancers) who were treated with radiotherapy. Radiotherapy was performed mainly in a palliative setting (n = 12; 63.2%), with a median dose of 45 Gy (range, 6-76 Gy). Infrequent major acute or late toxicities were reported. Among 19 patients, 9 (47.4%) experienced tumor progression, 5 (26.3%) experienced complete response, 2 (10.5%) experienced stable disease and/or partial response. At last follow-up, 12 patients (63.2%) had died; most deaths (n = 9) occurred because of the cancer. These results suggest that radiotherapy is feasible in the treatment of nonagenarian patients with gynecologic cancer.

A good educational climate/environment in the workplace is essential for developing high-quality medical (sub)specialists. These data are lacking for gynecological oncology training. This study aims to evaluate the educational climate in gynecological oncology training throughout Europe and the factors affecting it. A Web-based anonymous survey sent to ENYGO (European Network of Young Gynecological Oncologists) members/trainees to assess gynecological oncology training. This included sociodemographic information, details regarding training posts, and a 50-item validated Dutch Residency Educational Climate Test (D-RECT) questionnaire with 11 subscales (1-5 Likert scale) to assess the educational climate. The χ test was used for evaluating categorical variables, and the Mann-Whitney U (nonparametric) test was used for continuous variables between 2 independent groups. Cronbach α assessed the questionnaire reliability. Multivariable linear regression assessed the effect of variables on D-RECT outcome subscales. One hundred nineteen gynecological oncological fellows responded. The D-RECT questionnaire was extremely reliable for assessing the educational environment in gynecological oncology (subscales' Cronbach α, 0.82-0.96). Overall, trainees do not seem to receive adequate/effective constructive feedback during training. The overall educational climate (supervision, coaching/assessment, feedback, teamwork, interconsultant relationships, formal education, role of the tutor, patient handover, and overall consultant's attitude) was significantly better (P = 0.001) in centers providing accredited training in comparison with centers without such accreditation. Multivariable regression indicated the main factors independently associated with a better educational climate were presence of an accredited training post and total years of training. This study emphasizes the need for better feedback mechanisms and the importance of accreditation of centers for training in

Visits to Veterans Administration (VA) emergency departments (EDs) are increasingly being made by women. A 2011 national inventory of VA emergency services for women revealed that many EDs have gaps in their resources and processes for gynecologic emergency care. To guide VA in addressing these gaps, we sought to understand factors acting as facilitators and/or barriers to improving VA ED capacity for, and quality of, emergency gynecology care. Semistructured interviews with VA emergency and women's health key informants. ED directors/providers (n=14), ED nurse managers (n=13), and Women Veteran Program Managers (n=13) in 13 VA facilities. Leadership, staff, space, demand, funding, policies, and community were noted as important factors influencing VA EDs building capacity and improving emergency gynecologic care for women Veterans. These factors are intertwined and cross multiple organizational levels so that each ED's capacity is a reflection not only of its own factors, but also those of its local medical center and non-VA community context as well as VA regional and national trends and policies. Policies and quality improvement initiatives aimed at building VA's emergency gynecologic services for women need to be multifactorial and aimed at multiple organizational levels. Policies need to be flexible to account for wide variations across EDs and their medical center and community contexts. Approaches that build and encourage local leadership engagement, such as evidence-based quality improvement methodology, are likely to be most effective.

Full Text Available Layered ice bonded abrasive tools (LIBAT is a new kind of one which not only has the ability of lapping and polishing but also has the effect of self-dressing. In this paper, two kinds of layered ice bonded abrasive tools were designed and manufactured. Experimental studies on layered ice bonded abrasive (LIBA polishing of glass-ceramics were conducted. The results show that the surface topography of glass-ceramics polished by micro α-Al2O3-nano α-Al2O3 LIBAT is better than that of polished by micro α-Al2O3-nano SiO2 LIBAT. The surface roughness Sa of glass-ceramics polished by the two kinds of LIBAT is at the nanometer scale. The reasons of this phenomenon were analyzed. The experimental results illustrate that the LIBAT shows good effect and can be used in production practice. DOI: http://dx.doi.org/10.5755/j01.ms.20.4.6149

Additional projects are being planned, in Krakow and other cities, under the direction of FEWE-Krakow, the Polish Energie Cities Network, and Biuro Rozwoju Krakowa.

Nd:YOV4 laser polishing on WC-Co HVOF coating

Science.gov (United States)

Giorleo, L.; Ceretti, E.; Montesano, L.; La Vecchia, G. M.

2017-10-01

WC/Co coatings are widely applied to different types of components due to their extraordinary performance properties including high hardness and wear properties. In industrial applications High Velocity Oxy-Fuel (HVOF) technique is extensively used to deposit hard metal coatings. The main advantage of HVOF compared to other thermal spray techniques is the ability to accelerate the melted powder particles of the feedstock material at a relatively high velocity, leading to obtain good adhesion and low porosity level. However, despite the mentioned benefits, the surface finish quality of WC-Co HVOF coatings results to be poor (Ra higher than 5 µm) thus a mechanical polishing process is often needed. The main problem is that the high hardness of coating leads the polishing process expensive in terms of time and tool wear; moreover polishing becomes difficult and not always possible in case of limited accessibility of a part, micro dimensions or undercuts. Nowadays a different technique available to improve surface roughness is the laser polishing process. The polishing principle is based on focused radiation of a laser beam that melts a microscopic layer of surface material. Compared to conventional polishing process (as grinding) it ensures the possibility of avoiding tool wear, less pollution (no abrasive or liquids), no debris, less machining time and coupled with a galvo system it results to be more suitable in case of 3D complex workpieces. In this paper laser polishing process executed with a Nd:YOV4 Laser was investigated: the effect of different process parameters as initial coating morphology, laser scan speed and loop cycles were tested. Results were compared by a statistical approach in terms of average roughness along with a morphological analysis carried out by Scanning Electron Microscope (SEM) investigation coupled with EDS spectra.

2014-01-01

In this paper, an experimental investigation is implemented on the abrasive waterjet polishing technique to evaluate its capability in polishing of surfaces and edges of hydraulic turbine blades. For this, the properties of this method are studied and the main parameters affecting its performance are determined. Then, an experimental test-rig is designed, manufactured and tested to be used in this study. This test-rig can be used to polish linear and planar areas on the surface of the desired workpieces. Considering the number of parameters and their levels, the Taguchi method is used to design the preliminary experiments. All experiments are then implemented according to the Taguchi L 18 orthogonal array. The signal-to-noise ratios obtained from the results of these experiments are used to determine the importance of the controlled polishing parameters on the final quality of the polished surface. The evaluations on these ratios reveal that the nozzle angle and the nozzle diameter have the most important impact on the results. The outcomes of these experiments can be used as a basis to design a more precise set of experiments in which the optimal values of each parameter can be estimated

2013-01-01

Based on theoretical model of continuous polishing, the influence of processing parameters on the polishing result was discussed. Possible causes of mid-spatial frequency error in the process were analyzed. The simulation results demonstrated that the low spatial frequency error was mainly caused by large rotating ratio. The mid-spatial frequency error would decrease as the low spatial frequency error became lower. The regular groove shape was the primary reason of the mid-spatial frequency error. When irregular and fitful grooves were adopted, the mid-spatial frequency error could be lessened. Moreover, the workpiece swing could make the polishing process more uniform and reduce the mid-spatial frequency error caused by the fix-eccentric plane polishing. (authors)

Glaucio Serra

2013-12-01

Full Text Available INTRODUCTION: The finishing and polishing phases are essential to improve smoothness and shining on the surface of acrylic resins used to make removable orthodontic appliances. A good surface finishing reduces roughness, which facilitates hygiene, prevents staining and provides greater comfort to the patients. OBJECTIVE: The aim of this paper was to analyze the changes on surface morphology of acrylic resins during finishing and polishing phases. METHODS: Thirty discs (10 mm in diameter and 5 mm in length were made with acrylic resin and randomly divided into ten groups. The control group did not receive any treatment while the other groups received gradual finishing and polishing. The last group received the entire finishing and polishing procedures. Surface morphology was qualitatively analyzed through scanning electron microscopy and quantitatively analyzed through a laser profilometer test. RESULTS: The acrylic resin surfaces without treatment showed bubbles which were not observed in the subsequent phases. Wearing out with multilaminated burs, finishing with wood sandpaper and finishing with water sandpaper resulted in surfaces with decreasing irregularities. The surfaces that were polished with pumice and with low abrasive liquids showed high superficial smoothness. CONCLUSION: Highly smooth acrylic resin surfaces can be obtained after mechanical finishing and polishing performed with multilaminated burs, wood sandpaper, water sandpaper, pumice and low abrasive liquids.

Purpose: To analyze the impact of pathology review in gynecologic malignancies. Methods and Materials: For all new gynecologic patients seen between December 2, 1993 and January 4, 1996, we conducted a retrospective chart review to determine if a pathology review by the institute's consultant pathologist changed the diagnosis, and if so whether the change altered patient management. A total of 514 patients were seen, of whom 120 had cervical cancer, 226 had endometrial cancer, 122 had a primary ovarian or peritoneal malignancy, 9 had a vaginal malignancy, 28 had vulvar cancer, and 9 had a miscellaneous gynecologic malignancy. Results: On pathology review the diagnosis changed for 200 of 599 specimens (33%). This altered management for 63 of 514 patients (12%). For patients with cervical cancer, the grade of tumor was the main change in pathologic diagnosis, with occasional change in the presence of lymph vascular invasion. These did not translate into patient management alterations. Eight patients (1.5%) had management alterations. The changes in depth of invasion and vascular invasion altered management for 3 patients. Changes in pap smears resulted in two management alterations, and changes in histologic diagnoses altered management for 3 cases. For endometrial primaries the changes in pathologic diagnosis included grade, depth of invasion, and the presence of cervical involvement. This did alter management in 40 cases (8%). For the ovarian malignancies, the main changes were grade, extent of disease, or histologic classification, some of which (10 patients, 2%) resulted in altered management. One patient with a vaginal lesion had the diagnosis changed, which did alter management. Of the patients diagnosed with vulvar cancer, the pathologic diagnosis changed for 11 patients. This included changes in grade and depth of invasion. This altered management of 2 patients. The remaining miscellaneous gynecologic malignancies had only two diagnosis changes that altered

Full Text Available Objective: To analyze the social representation of adolescents about gynecological consultation and the influence of those in searching for consultations. Method: Qualitative descriptive study based on the Social Representations Theory, conducted with 50 adolescents in their last year of middle school. The data was collected between April and May of 2010 by Evocations and a Focal Group. The software EVOC and contextual analysis were used in the data treatment. Results: The elements fear and constraint, constant in the central nucleus, can justify the low frequency of adolescents in consultations. The term embarrassment in the peripheral system reinforce current sociocultural norms, while prevention, associated with learning about sex and clarifying doubts, allows to envision an educative function. Obtained testimonies in the focal groups exemplify and reinforce those findings. Conclusion: For an effective health education, professionals, including nurses, need to clarify the youth individually and collectively about their rights to privacy, secrecy, in addition to focus the gynecological consultation as a promotion measure to sexual and reproductive health.

Full Text Available Polish-German relations in the first half of 2014 were dominated by the Ukraine crisis. This study is an attempt to answer the question of how Polish and German press assessed the cooperation of both countries in resolving the conflict in Ukraine; to what extent the most widely read magazines associated themselves with the decisions of their politicians and the feelings of their own societies and how much understanding they showed for the arguments of their EU partner. The analysis focuses on the unprecedented mission of the Weimar Triangle foreign ministers to Ukraine in February 2014, which led to an agreement between the Ukrainian opposition and President Viktor Yanukovych. A turning point was the visit paid by Radoslaw Sikorski and Frank-Walter Steinmeier to St. Petersburg in June 2014. The next meetings agreed on by EU partners were held without inviting the Polish partner. In view of the speed of events in the selected time interval, the articles subjected to analysis were taken from the most widely read online editions of national daily newspapers in Poland and Germany.

Under EPRI sponsorship, an industry committee, similar in form and operation to other guideline committees, was created to develop Condensate Polishing Guidelines for both PWR and BWR systems. The committee reviewed the available utility and water treatment industry experience on system design and performance and incorporated operational and state-of-the-art information into document. These guidelines help utilities to optimize present condensate polisher designs as well as be a resource for retrofits or new construction. These guidelines present information that has not previously been presented in any consensus industry document. The committee generated guidelines that cover both deep bed and powdered resin systems as an integral part of the chemistry of PWR and BWR plants. The guidelines are separated into sections that deal with the basis for condensate polishing, system design, resin design and application, data management and performance and management responsibilities

Mechanistic, kinetic, and processing aspects of tungsten chemical mechanical polishing

Stein, David

This dissertation presents an investigation into tungsten chemical mechanical polishing (CMP). CMP is the industrially predominant unit operation that removes excess tungsten after non-selective chemical vapor deposition (CVD) during sub-micron integrated circuit (IC) manufacture. This work explores the CMP process from process engineering and fundamental mechanistic perspectives. The process engineering study optimized an existing CMP process to address issues of polish pad and wafer carrier life. Polish rates, post-CMP metrology of patterned wafers, electrical test data, and synergy with a thermal endpoint technique were used to determine the optimal process. The oxidation rate of tungsten during CMP is significantly lower than the removal rate under identical conditions. Tungsten polished without inhibition during cathodic potentiostatic control. Hertzian indenter model calculations preclude colloids of the size used in tungsten CMP slurries from indenting the tungsten surface. AFM surface topography maps and TEM images of post-CMP tungsten do not show evidence of plow marks or intergranular fracture. Polish rate is dependent on potassium iodate concentration; process temperature is not. The colloid species significantly affects the polish rate and process temperature. Process temperature is not a predictor of polish rate. A process energy balance indicates that the process temperature is predominantly due to shaft work, and that any heat of reaction evolved during the CMP process is negligible. Friction and adhesion between alumina and tungsten were studied using modified AFM techniques. Friction was constant with potassium iodate concentration, but varied with applied pressure. This corroborates the results from the energy balance. Adhesion between the alumina and the tungsten was proportional to the potassium iodate concentration. A heuristic mechanism, which captures the relationship between polish rate, pressure, velocity, and slurry chemistry, is presented

With the signing of the Medicare Access and CHIP Reauthorization Act in April 2015, the Centers for Medicare and Medicaid Services (CMS) is now positioned to drive the development and implementation of sweeping changes to how physicians and hospitals are paid for the provision of oncology-related services. These changes will have a long-lasting impact on the sub-specialty of gynecologic oncology, regardless of practice structure, physician employment and compensation model, or local insurance market. Recently, commercial payers have piloted various models of payment reform via oncology-specific clinical pathways, oncology medical homes, episode payment arrangements, and accountable care organizations. Despite the positive results of some pilot programs, adoption remains limited. The goals are to eliminate unnecessary variation in cancer treatment, provide coordinated patient-centered care, while controlling costs. Yet, meaningful payment reform in oncology remains elusive. As the largest payer for oncology services in the United States, CMS has the leverage to make cancer services more value based. Thus far, the focus has been around pricing of physician-administered drugs with recent work in the area of the Oncology Medical Home. Gynecologic oncology is a unique sub-specialty that blends surgical and medical oncology, with treatment that often involves radiation therapy. This forward-thinking, multidisciplinary model works to keep the patient at the center of the care continuum and emphasizes care coordination. Because of the breadth and depth of gynecologic oncology, this sub-specialty has both the potential to be disrupted by payment reform as well as potentially benefit from the aspects of reform that can align incentives appropriately to improve coordination. Although the precise future payment models are unknown at this time, focused engagement of gynecologic oncologists and the full care team is imperative to assure that the practice remains patient centered

Chemical Mechanical Polishing of Ruthenium, Cobalt, and Black Diamond Films

Peethala, Brown Cornelius

Ta/TaN bilayer serves as the diffusion barrier as well as the adhesion promoter between Cu and the dielectric in 32 nm technology devices. A key concern of future technology devices (layer (vs. a bilayer of Ta/TaN) to act as a barrier. During patterning, they need to be planarized using conventional chemical mechanical polishing (CMP) to achieve a planar surface. However, CMP of these new barrier materials requires novel slurry compositions that provide adequate selectivity towards Cu and dielectric films, and minimize galvanic corrosion. Apart from the application as a barrier, Ru also has been proposed as a lower electrode material in metal-insulator-metal capacitors where high (> 50 nm/min) Ru removal rates (RRs) are required and as a stop layer in magnetic recording head fabrication where low (hydroxide (KOH). It was also determined that increased the ionic strength is not responsible for the observed increase in Ru removal rate. Benzotirazole (BTA) and ascorbic acid were added to the slurry to reduce the open circuit potential (Eoc) difference between Cu and Ru to ˜20 mV from about 550 mV in the absence of additives. A removal mechanism with KIO4 as the oxidizing agent is proposed based on the formation of several ruthenium oxides, some of which formed residues on the polishing pad below a pH of ˜7. Next, a colloidal silica-based slurry with hydrogen peroxide (H 2O2) as the oxidizer (1 wt%), and arginine (0.5 wt%) as the complexing agent was developed to polish Co at pH 10. The Eoc between Cu and Co at the above conditions was reduced to ˜20 mV compared to ˜250 mV in the absence of additives, suggestive of reduced galvanic corrosion during the Co polishing. The slurry also has the advantages of good post-polish surface quality at pH 10, and no dissolution rate. BTA at a concentration of 5mM in this slurry inhibited Cu dissolution rates and yielded a Cu/Co RR ratio of ˜0.8:1 while the open potential difference between Cu and Co was further reduced to ˜10

This study compared the wear characteristics of a heat-pressed lithium disilicate ceramic material opposed to feldspathic porcelain, a lithium disilicate glass ceramic, and zirconia materials. Ceramic plate specimens were prepared from feldspathic porcelain (EX-3 nA1B), lithium disilicate glass ceramics (e.max CAD MO1/C14), and zirconia (Katana KT 10) and then ground or polished. Rounded rod specimens were fabricated from heat-pressed lithium disilicate glass ceramic (e.max press LT A3) and then glazed or polished. A sliding wear testing apparatus was used for wear testing. Wear of glazed rods was greater than that of polished rods when they were abraded with ground zirconia, ground porcelain, polished porcelain, or polished lithium disilicate ceramics. For both glazed and polished rods, wear was greater when the rods were abraded with ground plates. The findings indicate that application of a polished surface rather than a glazed surface is recommended for single restorations made of heat-pressed lithium disilicate material. In addition, care must be taken when polishing opposing materials, especially those used in occlusal contact areas. (J Oral Sci 58, 117-123, 2016).

A molecular dynamics method has been applied to study the mechanism of polishing based on vibrations of liquid. Movements of polishing particles and formations of impact dents are simulated and discussed. The abrasive effect between particle and machined substrate is evaluated empirically. Polishing qualities, including roughness and fractal character under multiple impacts, are obtained by numerical methods. Results show that the particle will vibrate and roll viscously on the substrate. Press, tear and self-organization effects will be responsible for the formation of impact dents. Simulation results are compared with experimental data to verify the conclusions

Full Text Available Background: The treatment of diseases by use of essential medicines, prescribed by generic names, has been emphasized by WHO and National Health Policy of India. Drugs used in gynaecology are one of the top selling drugs in India; however they are least studied with respect to drug utilization. Thus present study was undertaken to analyze drug utilization pattern of gynecology OPD in a tertiary care hospital. Materials and Methods: A retrospective, cross sectional, observational study of prescriptions in Gynecology OPD. Data was obtained from an electronic medical record database of patients that attended Gynecology OPD during the study period. Prescription records of patients were screened as per inclusion and exclusion criteria and 300 prescriptions were randomly selected by Openepi software. Patient related and drug related information was collected on a customized data collection sheet. Results: The mean age of patients was 30.19+9.83 years and common age of presentation was >18-30 years. In infective cases, vaginal discharge (10.33% was common, and in non-infective cases, menstrual disorders (24% were common. The average number of drugs per prescription was 3.47+1.53. In drug category, minerals (30.94% were most commonly prescribed, followed by antimicrobials (24.98%, and NSAIDs (13.37%. Polypharmacy was observed in 96.33% of the prescriptions. Conclusion: It is only by drug utilization studies that burden of diseases and corresponding utilization of drugs in gynecology can be measured. In our study majority of the drugs prescribed were generic which were from the essential medical list NLEM and WHO.

Complementary and alternative medicine (CAM) for treatment of cancer and for supportive care of cancer patients must be clearly separated. There is encouraging evidence for CAM in the latter area, such as acupuncture and progressive muscle relaxation for chemotherapy-related nausea and vomiting, and aromatherapy for decreasing anxiety and increasing quality of life. However, there are limited data about CAM used by gynecologic cancer patients, especially in Thai women. Therefore, the authors aimed to investigate the proportion and types of CAM using in our gynecologic cancer patients. This cross-sectional survey was conducted between October to December, 2008. Totals of 50 admitted and 50 walk-in gynecologic cancer patients 1 month after diagnosis, aged more than 20 years and able to give informed consent, were selected for one-by-one interview by random walking survey. Among the 100 interviewed patients, aged 21-69 (mean=50.12), there were 46 cases of cervical cancers, 35 of ovarian cancers, 18 of endometrial cancers (two of these also had ovarian cancers), 2 of malignant gestational trophoblastic diseases, 1 of vulvar cancer, and 1 liver cancer (in a patient with ovarian cancer). Some 67% (95% CI, 57.8-76.2%) of them used CAM. As diet modifications, 11 used Chinese vegetarian, 8 common vegetarian, 5 Cheewajit, and 1 macrobiotics. Five of them used dietary supplements while colonic detoxification was emplyed in three. As herbal medicines, 27 used Thai herbs, 4 Chinese herbs, and 1 a herbal sauna. Twelve were receiving Thai massage. As exercises, 23 used aerobics and 5 stretching. Interestingly, 62 of them used Buddhist praying while only 3 employed native magic. The three most common forms of CAM used by our gynecologic cancer patients were Buddhist praying (62/67, 92.5%), followed by herbal medicines (27/67, 40.3%) and exercises (25/67, 37.3%).

Contemporary training in obstetrics and gynecology is aimed at the acquisition of a complex set of skills oriented to both the technical and personal aspects of patient care. The ability to create clinical simulations through virtual reality (VR) may facilitate the accomplishment of these goals. The purpose of this paper is 2-fold: (1) to review the circumstances and equipment in industry, science, and education in which VR has been successfully applied, and (2) to explore the possible role of VR for training in obstetrics and gynecology and to suggest innovative and unique approaches to enhancing this training. Qualitative assessment of the literature describing successful applications of VR in industry, law enforcement, military, and medicine from 1995 to 2000. Articles were identified through a computer-based search using Medline, Current Contents, and cross referencing bibliographies of articles identified through the search. One hundred and fifty-four articles were reviewed. This review of contemporary literature suggests that VR has been successfully used to simulate person-to-person interactions for training in psychiatry and the social sciences in a variety of circumstances by using real-time simulations of personal interactions, and to launch 3-dimensional trainers for surgical simulation. These successful applications and simulations suggest that this technology may be helpful and should be evaluated as an educational modality in obstetrics and gynecology in two areas: (1) counseling in circumstances ranging from routine preoperative informed consent to intervention in more acute circumstances such as domestic violence or rape, and (2) training in basic and advanced surgical skills for both medical students and residents. Virtual reality is an untested, but potentially useful, modality for training in obstetrics and gynecology. On the basis of successful applications in other nonmedical and medical areas, VR may have a role in teaching essential elements

Nanoparticles have been widely used in polishing slurry such as chemical mechanical polishing (CMP) process. The movement of nanoparticles in polishing slurry and the interaction between nanoparticles and solid surface are very important to obtain an atomic smooth surface in CMP process. Polishing slurry contains abrasive nanoparticles (with the size range of about 10-100 nm) and chemical reagents. Abrasive nanoparticles and hydrodynamic pressure are considered to cause the polishing effect. Nanoparticles behavior in the slurry with power-law viscosity shows great effect on the wafer surface in polishing process. CMP is now a standard process of integrated circuit manufacturing at nanoscale. Various models can dynamically predict the evolution of surface topography for any time point during CMP. To research, using a combination of individual nanoscale friction measurements for CMP of SiO{sub 2}, in an analytical model, to sum these effects, and the results scale CMP experiments, can guide the research and validate the model. CMP endpoint measurements, such as those from motor current traces, enable verification of model predictions, relating to friction and wear in CMP and surface topography evolution for different types of CMP processes and patterned chips. In this article, we explore models of the microscopic frictional force based on the surface topography and present both experimental and theoretical studies on the movement of nanoparticles in polishing slurry and collision between nanoparticles, as well as between the particles and solid surfaces in time of process CMP. Experimental results have proved that the nanoparticle size and slurry properties have great effects on the polishing results. The effects of the nanoparticle size and the slurry film thickness are also discussed.

The purpose of this study was to investigate the effect of different air-polishing powders on the color stability of different types of composite resin restorative materials. Thirty cylindrical specimens (15×2 mm) were prepared for each of 7 composite resin restorative materials. All specimens were polished with a series of aluminum oxide polishing discs (Sof-Lex). The prepared specimens of each composite resin were randomly divided into 3 groups of 10 specimens each, for control (Group-C) and two air-powder applications (Group-CP: Cavitron Prophy-Jet; Group-PS: Sirona ProSmile prophylaxis powder). A standard air-polishing unit (ProSmile Handly) was used. All specimens were air-powdered for 10 s at 4-bar pressure. The distance of the spray nosel from the specimens was approximately 10 mm and angulation of the nosel was 90°. Specimens were stored in 100 mL of coffee (Nescafe Classic) for 24 h at 37°C. Color measurement of all specimens was recorded before and after exposure to staining agent with a colorimeter (Minolta CR-300). Color differences (∆E*) between the 2 color measurements (baseline and after 24 h storage) were calculated. The data were analyzed with a 2-way ANOVA test, and mean values were compared by the Tukey HSD test (p.05) and these groups demonstrated the highest ∆E* values. For Filtek Silorane and IntenS, the highest ∆E* values were observed in Group-PS. The lowest ∆E* values for all composite resin groups were observed in Group-C. When comparing the 7 composite resin restorative materials, Aelite Aesthetic Enemal demonstrated significantly less ∆E* values than the other composite resins tested. The highest ∆E* values were observed in Quixfil. Except for Quixfil, all control groups of composite resins that were polished Sof-Lex exhibited clinically acceptable ∆E values (<3.7). Air-polishing applications increased the color change for all composite resin restorative materials tested. Composite restorations may require re-polishing

Material removal mechanisms in electrochemical-mechanical polishing of tantalum

International Nuclear Information System (INIS)

Gao, F.; Liang, H.

2009-01-01

Material removal mechanisms in tantalum chemical-mechanical polishing (CMP) and electrochemical-mechanical polishing (ECMP) were investigated using the single frequency electrochemical impedance spectroscopy (EIS). Through measuring the impedance of the tantalum surface, the single frequency EIS scan made it possible to observe the CMP and ECMP processes in situ. The impedance results presented competing mechanisms of removal and formation of a surface oxide layer of tantalum. Analysis indicated that the thickness of the oxide layer formed during polishing was related to the mechanical power correlated to the friction force and the rotating speed. Furthermore, the rate of growth and removal of the oxide film was a function of the mechanical power. This understanding is beneficial for optimization of CMP and ECMP processes.

[Polish medical ethics in the period 1945-1980].

2003-01-01

The purpose of this article is o present that main currents of Polish medical ethics in the years 1945-1980, which the author treats as the 'prehistory' of Poland's contemporary bioethics. The author begins by ascertaining the post-war disappearance of two Polish traditions--that of the Warsaw school of philosopher-physicians (known in the West as the Polish School of Philosophy of Medicine) and the Lwów-Warsaw School of Philosophy. The political system that come into being after 1945 was not conducive to the development of medical ethics, but several clear orientations may be discerned in the utterances of physicians, lawyers, moral technologlans and academic philosophers.

2018-03-08

The American Academy of Pediatrics and American College of Obstetricians and Gynecologists have identified the menstrual cycle as essential in assessing overall health of adolescent girls. Menses should be considered a "vital sign" and documentation of last menstrual period (LMP) is recommended at every patient encounter. The aim of this study was to estimate and compare LMP documentation among adolescent and pediatric health care providers. A retrospective cohort study identified a random sample of 50 female patients seen in the general pediatrics (PEDS), adolescent medicine (AM), and pediatric and adolescent gynecology (PAG) ambulatory clinics at Phoenix Children's Hospital between January 1, 2016 and March 31, 2016. Rates of LMP documentation were compared between clinics using the Pearson χ 2 test. Multivariable logistic regression analyses quantified the association of clinic and LMP documentation, with adjustments for visit reason, provider gender, and age at presentation. Rates of LMP documentation were 100% for adolescent gynecologists, but significantly lower for general pediatricians (14%) and AM (60%) providers (P < .0001). These findings were confirmed in multivariable analyses (PAG vs PEDS: odds ratio [OR], 280; 95% confidence interval [CI], 32-2331; PAG vs AM: OR, 34; 95% CI, 4.4-270; AM vs PEDS: OR, 3.8; 95% CI, 1.3-11.0). Adolescent gynecologists document LMP routinely. In contrast, LMP documentation rates in AM, and especially in PEDS, were significantly lower. Quality improvement methods such as incorporation of an LMP section into the vitals portion of an electronic medical record could help improve rates of compliance.

To evaluate the surface roughness of IPS Empress 2 ceramic when treated with different finishing/polishing protocols. Sixteen specimens of IPS Empress 2 ceramic were made from wax patterns obtained using a stainless steel split mold. The specimens were glazed (Stage 0-S0, control) and divided into two groups. The specimens in Group 1 (G1) were finished/polished with a KG Sorensen diamond point (S1), followed by KG Sorensen siliconized points (S2) and final polishing with diamond polish paste (S3). In Group 2 (G2), the specimens were finished/polished using a Shofu diamond point (S1), as well as Shofu siliconized points (S2) and final polishing was performed using Porcelize paste (S3). After glazing (S0) and following each polishing procedure (S1, S2 or S3), the surface roughness was measured using TALYSURF Series 2. The average surface roughness results were analyzed using ANOVA followed by Tukey post-hoc tests (α = 0.01) RESULTS: All of the polishing procedures yielded higher surface roughness values when compared to the control group (S0). S3 yielded lower surface roughness values when compared to S1 and S2. The proposed treatments negatively affected the surface roughness of the glazed IPS Empress 2 ceramic.

PURPOSE The purposes of this study were to evaluate the staining resistance of CAD/CAM resin-ceramics polished with different techniques and to determine the effectiveness of the polishing techniques on resin-ceramics, comparing it with that of a glazed glass-ceramic. MATERIALS AND METHODS Four different CAD/CAM ceramics (feldspathic ceramic: C-CEREC Blocs, (SIRONA) and three resin-ceramics: L-Lava Ultimate, (3M ESPE), E-Enamic, (VITA) and CS-CeraSmart, (GC)) and one light cure composite resin: ME-Clearfil Majesty Esthetic (Kuraray) were used. Only C samples were glazed (gl). Other restorations were divided into four groups according to the polishing technique: nonpolished control group (c), a group polished with light cure liquid polish (Biscover LV BISCO) (bb), a group polished with ceramic polishing kit (Diapol, EVE) (cd), and a group polished with composite polishing kit (Clearfil Twist Dia, Kuraray) (kc). Glazed C samples and the polished samples were further divided into four subgroups and immersed into different solutions: distilled water, tea, coffee, and fermented black carrot juice. Eight samples (8 × 8 × 1 mm) were prepared for each subgroup. According to CIELab system, four color measurements were made: before immersion, immersion after 1 day, after 1 week, and after 1 month. Data were analyzed with repeated measures of ANOVA (α=.05). RESULTS The highest staining resistance was found in gl samples. There was no difference among gl, kc and cd (P>.05). Staining resistance of gl was significantly higher than that of bb (PCeramic and composite polishing kits can be used for resin ceramics as a counterpart of glazing procedure used for full ceramic materials. Liquid polish has limited indications for resin ceramics. PMID:28018558

The design and fabrication of electrodes for direct current (dc) high voltage photoemission electron guns can significantly influence their performance, most notably in terms of maximum achievable bias voltage. Proper electrostatic design of the triple-point junction shield electrode minimizes the risk of electrical breakdown (arcing) along the insulator-cable plug interface, while the electrode shape is designed to maintain work, we describe a centrifugal barrel-polishing technique commonly used for polishing the interior surface of superconducting radio frequency cavities but implemented here for the first time to polish electrodes for dc high voltage photoguns. The technique reduced polishing time from weeks to hours while providing surface roughness comparable to that obtained with diamond-paste polishing and with unprecedented consistency between different electrode samples. We present electrode design considerations and high voltage conditioning results to 360 kV (˜11 MV/m), comparing barrel-polished electrode performance to that of diamond-paste polished electrodes. Tests were performed using a dc high voltage photogun with an inverted-geometry ceramic insulator design.

This study aimed to investigate the surface roughness and gloss of composite resins after using two polishing systems and toothbrushing. Six composite resins (Durafill VS, Filtek Z250, Filtek Z350 XT, Kalore, Venus Diamond, and Venus Pearl) were evaluated after polishing with two polishing systems (Sof-Lex, Venus Supra) and after toothbrushing up to 40,000 cycles. Surface roughness (Ra) and gloss were determined for each composite resin group (n=6) after silicon carbide paper grinding, polishing, and toothbrushing. Two-way ANOVA indicated significant differences in both Ra and gloss between measuring stages for the composite resins tested, except Venus Pearl, which showed significant differences only in gloss. After polishing, the Filtek Z350 XT, Kalore, and Venus Diamond showed significant increases in Ra, while all composite resin groups except the Filtek Z350 XT and Durafill VS with Sof-Lex showed increases in gloss. After toothbrushing, all composite resin demonstrated increases in Ra and decreases in gloss.

The psychosexual concerns of gynecologic cancer patients are often unaddressed and there are limited resources available for women to deal with this highly sensitive topic. This feasibility study examines the participation rates and preliminary outcomes for an online support group designed specifically for women who are sexually distressed subsequent to gynecologic cancer treatment A 12-week online intervention was developed to address the psychosexual impact of gynecologic cancer. This intervention included a professionally moderated, asynchronous discussion forum as well as the provision of psycho-educational materials addressing the psychosexual impact of gynecologic cancer. Each week, a new topic was introduced and relevant material was posted on the website. Women were encouraged to share their experiences related to the topic. Twenty-seven, sexually distressed, remitted gynecologic cancer patients were randomly assigned to immediate treatment or a waitlist control condition. Participants completed questionnaires at baseline, 4-month and 8-month follow-ups assessing sexual distress as the primary outcome as well as anxiety, depression, and illness intrusiveness. Participation rates differed between the two groups, with greater participation occurring in the second group. Exit interviews indicated that the majority of the participants were satisfied with the intervention. Intent-to-treat analyses suggest a small effect for reduction in sexual distress This feasibility study suggests that women find this intervention acceptable. Further research is required to determine efficacy. Copyright © 2012 John Wiley & Sons, Ltd.

Finishing and polishing an amalgam restoration, is considered as an important and necessary step of the restorative procedure. Various polishing techniques have been recommended to success a smooth amalgam surface. The aim of this study was to investigate the influence of three different polishing treatments on the marginal integrity and surface smoothness of restorations made of three commercially available amalgams and a glass-cermet cement. The materials used were the amalgams, Amalcap (Vivadent), Dispersalloy (Johnson and Johnson), Duralloy (Degussa) and the glass-cermet Katac-Silver (ESPE). The occlusal surfaces of the restorations were polished by the methods: I) round bur, No4-rubber cup-zinc oxide paste in a small brush, II) round bur No 4-bur-brown, green and super green (Shofu) polishing cups and points successively and III) amalgam polishing bur of 12-blades-smooth amalgam polishing bur. Photographs from unpolished and polished surfaces of the restorations, were taken with scanning electron microscope, to evaluate the polishing techniques. An improvement of marginal integrity and surface smoothness of all amalgam restorations was observed after the specimens had been polished with the three techniques. Method II, included Shofu polishers, proved the best results in comparison to the methods I and III. Polishing of glass-cermet cement was impossible with the examined techniques.

There is a lack of Polish tools to measure behaviour related to orthorexia nervosa. The purpose of the present study was to validate the Polish version of the ORTHO-15 test. 341 women and 59 men (N = 400) were recruited, whose age ranged from 18 to 35 years. Mean age was 23.09 years (SD = 3.14) in women and 24.02 years (SD = 3.87) in men. The ORTHO-15 test and the EAT-26 test were used in the present study. Factor analysis (exploratory and confirmatory analysis) was used in the present study. Exploratory factor analysis performed on the initial 15 items from a random split half of the study group suggested a nine-item two-factor structure. Confirmatory factor analysis performed on the second randomly selected half of the study group supported this two-factor structure of the ORTHO-15 test. The Polish version of the ORTHO-15 test demonstrated an internal consistency (Cronbach's alpha) equal to 0.644. The Polish version of the ORTHO-15 test is a reliable and valuable instrument to assess obsessive attitudes related to healthy and proper nutrition in Polish female and male population.

This study compared the roughness of porcelain polished or glazed surfaces and the adhesion of oral streptococcus mutans to them in vitro. 30 porcelain samples were made. Porcelain samples in group A were polished with diamond paste. Porcelain samples were glazed in group B and were polished with Al2O3 (240#) bur in group C. Their roughness values were measured by profilometer. Standardized cell suspensions were incubated with test samples for one hour at 37 degrees C, then retained cells were counted by image analysis (percentage area of a microscopic field covered by cells). Roughness values of group A, B, C were respectively (0.1987 +/- 0.057) microm, (0.1990 +/- 0.091) microm, (0.4260 +/- 0.174) microm. There was no significantly difference between group A and group B. The roughness samples in group C were significantly rougher than that in the other groups. The amount of retained cells in group A, group B, group C was respectively (15.92 +/- 4.37)%, (16.39 +/- 6.31)% and (41.48 +/- 12.1)%. There was no significant difference between the cell adhesion on porcelain surface glazed and polished, but more bacteria adhered on the porcelain surface in group C. Porcelain surface polished treatment was clinically acceptable compared with its glazed. They all exhibited the least amount of bacteria adhesion. The more porcelain surface was rough, the more bacteria adhered on it.

Modern particle accelerators require minimal interior surface roughness for Niobium superconducting radio frequency (SRF) cavities. Polishing of the Nb is currently achieved via electrochemical polishing with concentrated mixtures of sulfuric and hydrofluoric acids. This acid-based approach is effective at reducing the surface roughness to acceptable levels for SRF use, but due to acid-related hazards and extra costs (including safe disposal of used polishing solutions), an acid-free method would be preferable. This study focuses on an alternative electrochemical polishing method for Nb, using a novel ionic liquid solution containing choline chloride, also known as Vitamin B 4 (VB 4 ). Potentiostatic electrochemical impedance spectroscopy (EIS) was also performed on the VB4-based system. Nb polished using the VB4-based method was found to have a final surface roughness comparable to that achieved via the acid-based method, as assessed by atomic force microscopy (AFM). These findings indicate that acid-free VB 4 -based electrochemical polishing of Nb represents a promising replacement for acid-based methods of SRF cavity preparation

2015-01-01

Highlights: • Graphene was deposited on polished and ground Cu sheets by CVD. • Graphene films provide better protection to polished Cu for short time. • Multilayer graphene films provide better protection for short time. - Abstract: Graphene was deposited on Cu sheets with different morphologies by chemical vapor deposition. Scanning electron microscopy (SEM) analysis indicated that the morphology of the Cu sheet affected the graphene film properties. Electrochemical impedance spectroscopy measurements showed that the graphene film did not effectively protect Cu against corrosion because of prolonged exposure to ionic environments (3.5 wt.% NaCl solution). For short durations, graphene films provided better protection to polished Cu than ground Cu. Prolonged electrolyte immersion of graphene-coated Cu samples showed that the graphene film from the polished Cu surface was detached more easily than that from ground Cu

2002-01-01

Since totally unpolished rice has poor cooking quality, a certain amount of polishing for the removal of the outermost bran layers is essential. To determine the best combination of polishing time and pressure with respect to obtaining optimum quantity/quality, the brown rice (head grains) of a rice strain 4048 was milled for 10, 20, 30 and 40 seconds against 1,2,3,4 and 5 lbs pressure in a Burrows McGill Polisher No. 3. the quality characteristics studied were: total milling recovery, head rice recovery, whiteness of milled rice, protein content of grain, grain length and bursting upon cooking. Both, total milled rice and head rice reduced while the whiteness of milled rice improved significantly with an increase in polishing time and or pressure. The protein content decreased gradually with an increase in time and pressure of milling but the effect was non significant. The cooked grain length increased with an increase in milling degree up to a stage, beyond which it declined. The increase in bursting of grains on cooking. A combination of 20 seconds polishing time with 2 lbs pressure or 20 seconds polishing time with 3 lbs pressure was found to be the best combination of obtaining the optimum quality as well as the quality of milled rice.(author)

Objective This study aims to examine whether gynecologic conditions are associated with chronic fatigue syndrome (CFS). Methods This study includes a subset of 157 women from a population-based case-control study in Georgia, United States, conducted in 2004-2009. Gynecologic history was collected using a self-administered questionnaire. Crude odds ratios (ORs) with 95% CIs and ORs adjusted for body mass index and other covariates, where relevant, were estimated for gynecologic conditions between 84 CFS cases and 73 healthy controls. Results Cases and controls were of similar age. Women with CFS reported significantly more gynecologic conditions and surgical operations than controls: menopause status (61.9% vs 37.0%; OR, 2.37; 95% CI, 1.21-4.66), earlier mean age at menopause onset (37.6 vs 48.6 y; adjusted OR, 1.22; 95% CI, 1.09-1.36), excessive menstrual bleeding (73.8% vs 42.5%; adjusted OR, 3.33; 95% CI, 1.66-6.70), bleeding between periods (48.8% vs 23.3%; adjusted OR, 3.31; 95% CI, 1.60-6.86), endometriosis (29.8% vs 12.3%; adjusted OR, 3.67; 95% CI, 1.53-8.84), use of noncontraceptive hormonal preparations (57.1% vs 26.0%; adjusted OR, 2.95; 95% CI, 1.36-6.38), nonmenstrual pelvic pain (26.2% vs 2.7%; adjusted OR, 11.98; 95% CI, 2.57-55.81), and gynecologic surgical operation (65.5% vs 31.5%; adjusted OR, 3.33; 95% CI, 1.66-6.67), especially hysterectomy (54.8% vs 19.2%; adjusted OR, 3.23; 95% CI, 1.46-7.17). Hysterectomy and oophorectomy occurred at a significantly younger mean age in the CFS group than in controls and occurred before CFS onset in 71% of women with records of date of surgical operation and date of CFS onset. Conclusions Menstrual abnormalities, endometriosis, pelvic pain, hysterectomy, and early/surgical menopause are all associated with CFS. Clinicians should be aware of the association between common gynecologic problems and CFS in women. Further work is warranted to determine whether these conditions contribute to the development and

Advanced gynecological surgery undertaken in a specialized gynecologic oncology unit may be associated with significant perioperative morbidity. Validated risk prediction models are available for general surgical specialties but currently not for gynecological cancer surgery. The objective of this study was to evaluate risk factors for adverse events (AEs) of patients treated for suspected or proven gynecological cancer and to develop a clinical risk score (RS) to predict such AEs. AEs were prospectively recorded and matched with demographical, clinical and histopathological data on 369 patients who had an abdominal or laparoscopic procedure for proven or suspected gynecological cancer at a tertiary gynecological cancer center. Stepwise multiple logistic regression was used to determine the best predictors of AEs. For the risk score (RS), the coefficients from the model were scaled using a factor of 2 and rounded to the nearest integer to derive the risk points. Sum of all the risk points form the RS. Ninety-five patients (25.8%) had at least one AE. Twenty-nine (7.9%) and 77 (20.9%) patients experienced intra- and postoperative AEs respectively with 11 patients (3.0%) experiencing both. The independent predictors for any AE were complexity of the surgical procedure, elevated SGOT (serum glutamic oxaloacetic transaminase, > or /=35 U/L), higher ASA scores and overweight. The risk score can vary from 0 to 14. The risk for developing any AE is described by the formula 100 / (1 + e((3.697 - (RS /2)))). RS allows for quantification of the risk for AEs. Risk factors are generally not modifiable with the possible exception of obesity.

There are limited data regarding the end-of-life care for women with gynecologic malignancies. We set out to generate pilot data describing the care that women with gynecologic malignancies received in the last 6 months of life. Patient demographics, patterns of care, and utilization of palliative medicine consultation services were evaluated. One hundred patients who died of gynecologic malignancies were identified in our institutional database. Only patients who had received treatment with a gynecologic oncologist within 1 year of death were included. Medical records were reviewed for relevant information. Data were abstracted from the electronic medical record, and analyses were made using Student t test and Mann-Whitney U test with SPSS software. The mean age of patients was 60 years (range, 30-94 years). Racial/ethnic distribution was as follows: 38%, white; 34%, black; and 15%, Hispanic. Seventy-five percent of patients received chemotherapy within the last 6 months of life, and 30% received chemotherapy within the last 6 weeks of life. The median number of days hospitalized during the last 6 months of life was 24 (range, 0-183 days). During the last 6 months of life, 19% were admitted to the intensive care unit, 17% were intubated, 5% had terminal extubation, and 13% had cardiopulmonary resuscitative efforts. Sixty-four percent had a family meeting, 50% utilized hospice care, and 49% had palliative medicine consultations. There was a significant difference in hospice utilization when comparison was made between patients who had 14 days or more from consultation until death versus patients who had 14 days or less or no consultation, 21 (72%) versus 29 (41%), P = 0.004. Patients who were single were less likely to have a palliative medicine consultation, P = 0.005. End-of-life care for patients with gynecologic malignancies often includes futile, aggressive treatments and invasive procedures. It is unknown whether these measures contribute to longevity or

We first present a Case Study - the manufacture of 1.4 m prototype mirror-segments for the European Extremely Large Telescope, undertaken by the National Facility for Ultra Precision Surfaces, at the OpTIC facility operated by Glyndwr University. Scale-up to serial-manufacture demands delivery of a 1.4 m off-axis aspheric hexagonal segment with surface precision robots and computer numerically controlled ('CNC') polishing machines for optical fabrication. The objective was not to assess which is superior. Rather, it was to understand for the first time their complementary properties, leading us to operate them together as a unit, integrated in hardware and software. Three key areas are reported. First is the novel use of robots to automate currently-manual operations on CNC polishing machines, to improve work-throughput, mitigate risk of damage to parts, and reduce dependence on highly-skilled staff. Second is the use of robots to pre-process surfaces prior to CNC polishing, to reduce total process time. The third draws the threads together, describing our vision of the automated manufacturing cell, where the operator interacts at cell rather than machine level. This promises to deliver a step-change in end-to-end manufacturing times and costs, compared with either platform used on its own or, indeed, the state-of-the-art used elsewhere.

Evidence has shown that multidisciplinary tumor board conferences (MTBCs) improve patient management for various cancer types. However, few retrospective studies have investigated MTBC efficacy for patients with gynecologic cancers. Here, we prospectively aimed to evaluate how MTBCs influence patient management in gynecologic oncology. This prospective study included 85 consecutive cases that were presented at gynecologic oncology MTBCs in our tertiary university hospital between January 2015 and April 2016. The primary endpoint was treatment plan change rate, which included both major and minor changes. Major changes were defined as exchange, addition, or subtraction of treatment modality. Minor changes included all other, such as intramodality changes or treatment time changes. The secondary endpoints were the change rates of diagnosis, diagnostic work-up, and radiological and pathological findings.The treatment plan change rate, irrespective of changes in diagnostic work-up, was 27.1%, which included 10.6% major and 16.5% minor changes. Among the treatment plan changes, changes in the treatment plan change rate alone were noted in 16.5% of cases, and changes in diagnosis and radiological findings occurred in 7.1% and 3.5% of cases, respectively. Diagnosis and radiological findings, irrespective of changes in diagnostic work-up, were also changed in 9.4% and 10.6% of cases, respectively. However, there were no changes in pathological findings. Moreover, there was a change of diagnostic method for further work-up in 23.5% of cases. The implementation rate of MTBC-determined treatment changes was 91.8%. Gynecologic oncology MTBCs resulted in considerable changes in treatment plans. Diagnosis, diagnostic work-up, and radiological findings were influenced by MTBCs. The data emphasize the importance of adopting a multidisciplinary team approach for gynecologic cancer management.

ROUGHNESS ANALYSIS OF VARIOUSLY POLISHED NIOBIUM SURFACES

Energy Technology Data Exchange (ETDEWEB)

Ribeill, G.; Reece, C.

2008-01-01

Niobium superconducting radio frequency (SRF) cavities have gained widespread use in accelerator systems. It has been shown that surface roughness is a determining factor in the cavities’ effi ciency and maximum accelerating potential achievable through this technology. Irregularities in the surface can lead to spot heating, undesirable local electrical fi eld enhancement and electron multipacting. Surface quality is typically ensured through the use of acid etching in a Buffered Chemical Polish (BCP) bath and electropolishing (EP). In this study, the effects of these techniques on surface morphology have been investigated in depth. The surface of niobium samples polished using different combinations of these techniques has been characterized through atomic force microscopy (AFM) and stylus profi lometry across a range of length scales. The surface morphology was analyzed using spectral techniques to determine roughness and characteristic dimensions. Experimentation has shown that this method is a valuable tool that provides quantitative information about surface roughness at different length scales. It has demonstrated that light BCP pretreatment and lower electrolyte temperature favors a smoother electropolish. These results will allow for the design of a superior polishing process for niobium SRF cavities and therefore increased accelerator operating effi ciency and power.

In this paper, a Multi-objective particle swarm optimization algorithm (MOPSOA) is applied to optimize surface roughness of workpiece after circular magnetic abrasive polishing. The most important parameters of polishing model, namely current, gap between pole and workpiece, spindle speed and polishing time, were considered in this approach. The objective functions of the MOPSOA depend on the quality of surface roughness of polishing materials with both simultaneous surfaces (Ra1, Ra2), which are determined by means of experimental approach with the aid of circular magnetic field. Finally, the effectiveness of the approach is compared between the optimal results with the experimental data. The results show that the new proposed polishing optimization method is more feasible.

Eating disorders are an important factor in menstrual cycle disorders in girls. Moreover, low self-esteem among adolescent girls may be a risk factor for eating disorders. The aim of the study was to assess the menstrual cycle, eating habits and self-esteem of Polish adolescents. The study was conducted from January 2014 to March 2015 and included 623 girls, aged 15-19, from randomly selected junior high schools in Silesia, Poland, in which their menstrual cycle, risk of eating disorders and self-esteem were evaluated. A five-part questionnaire was used to assess basic demographic data, lifestyle and physical activity, gynecological history, as well as Rosenberg Self-Esteem Scale (SES) and Eating Attitude Test (EAT-26). Irregular menstrual cycles were observed in 236 (37.88%) girls; 5.20% presented secondary amenorrhea. Based on the EAT-26 test, 101 (16.21%) girls were indicated being at risk for an eating disorder. Low self-esteem was observed in 340 (54.57%) study girls on the base of SES. Girls with irregular menses had higher scores on the EAT-26 test in subscales: EAT-overall score, EAT-diet and EAT-bulimia, while lower scores on the SES. In our study, we did not observe a significant relationship between exercise intensity, body mass, BMI and menstrual cycle regularity. Low self-esteem among adolescent girls may be a risk factor for eating disorders which could interrupt the menstrual cycle.

Izabela Kowalik

2017-09-01

Full Text Available Objective: The study goal was the investigation of relationships between accelerated internationalisation descriptors and antecedent firm- and entrepreneur-related factors in Polish and Czech SMEs. Research Design & Methods: In order to compare Polish and Czech companies, the data collected in two independent studies were used. The study of 233 Polish companies was conducted with the use of CATI method in 2014; 108 Czech companies were surveyed in 2013/2014 with the use of CAWI method. In both samples half of the surveyed SME-exporters were conforming to the accelerated internationalisation criteria. Findings: In both samples the “global vision” elements and company internationalisation scale and speed were interrelated. In the Polish companies this relationship was moderated by company size. There was the lack of strong positive relationships between innovativeness and internationalisation speed and scale in both samples. Implications & Recommendations:The managerial mindset has a decisive role for accelerated internationalisation in both Czech and Polish SMEs. The innovativeness of offering is not indispensable for fast foreign expansion. Larger companies may expand abroad faster if they have internationally oriented managers. Contribution & Value Added:This work addresses a research gap concerning idiosyncrasies of internationalisation antecedents in Polish and Czech enterprises. As the results show, there is no common internationalisation pattern for Polish and Czech SMEs.

The clinical applications of high-translucency monolithic zirconia restorations have increased. Chairside and laboratory adjustments of these restorations are inevitable, which may lead to increased roughness and reduced strength. The influence of grinding and polishing on high-translucency zirconia has not been investigated. The purpose of this in vitro study was to compare the roughness averages (Ra) of ground and polished zirconia and investigate whether roughness influenced strength after aging. High-translucency zirconia disks were milled, sintered, and glazed according to the manufacturer's recommendations. Specimens were randomized to 4 equal groups. Group G received only grinding; groups GPB and GPK received grinding and polishing with different polishing systems; and group C was the (unground) control group. All specimens were subjected to hydrothermal aging in an autoclave at 134°C at 200 kPa for 3 hours. Roughness average was measured using a 3-dimensional (3D) optical interferometer at baseline (Ra1), after grinding and polishing (Ra2), and after aging (Ra3). A biaxial flexural strength test was performed at a rate of 0.5 mm/min. Statistical analyses were performed using commercial software (α=.05). Group G showed a significantly higher mean value of Ra3 (1.96 ±0.32 μm) than polished and glazed groups (P.05). Compared with baseline, the roughness of groups G and GPB increased significantly after surface treatments and after aging, whereas aging did not significantly influence the roughness of groups GPK or C. Group G showed the lowest mean value of biaxial flexural strength (879.01 ±157.99 MPa), and the highest value was achieved by group C (962.40 ±113.84 MPa); no statistically significant differences were found among groups (P>.05). Additionally, no significant correlation was detected between the Ra and flexural strength of zirconia. Grinding increased the roughness of zirconia restorations, whereas proper polishing resulted in smoothness

Dybowski, J. [Polish Power Grid Co., Warsaw (Poland)

1995-12-01

This paper represents the strategy for development of the Polish Electricity Sector dealing with specific problems which are common for all of East Central Europe. In 1990 Poland adopted a restructuring program for the entire energy sector. Very ambitious plans were changed several times but still the main direction of change was preserved. The most difficult period of transformation is featured by several contradictions which have to be balanced. Electricity prices should increase in order to cover the modernization and development program but the society is not able to take this burden in such a short time. Furthermore the new environment protection standards force the growth of capital investment program which sooner or later has to be transferred through the electricity prices. New economic mechanisms have to be introduced to the electricity sector to replace the old ones noneffective, centrally planned. This process has to follow slow management changes. Also, introduction of new electricity market is limited by those constraints. However, this process of change would not be possible without parallel governmental initiation like preparation of new energy law and regulatory frames.

Yoon, Hyung-In; Noh, Hyo-Mi; Park, Eun-Jin

2017-06-01

This study was to evaluate the effect of repeated ultrasonic scaling and surface polishing with intraoral polishing kits on the surface roughness of three different restorative materials. A total of 15 identical discs were fabricated with three different materials. The ultrasonic scaling was conducted for 20 seconds on the test surfaces. Subsequently, a multi-step polishing with recommended intraoral polishing kit was performed for 30 seconds. The 3D profiler and scanning electron microscopy were used to investigate surface integrity before scaling (pristine), after scaling, and after surface polishing for each material. Non-parametric Friedman and Wilcoxon signed rank sum tests were employed to statistically evaluate surface roughness changes of the pristine, scaled, and polished specimens. The level of significance was set at 0.05. Surface roughness values before scaling (pristine), after scaling, and polishing of the metal alloys were 3.02±0.34 µm, 2.44±0.72 µm, and 3.49±0.72 µm, respectively. Surface roughness of lithium disilicate increased from 2.35±1.05 µm (pristine) to 28.54±9.64 µm (scaling), and further increased after polishing (56.66±9.12 µm, P scaling (from 1.65±0.42 µm to 101.37±18.75 µm), while its surface roughness decreased after polishing (29.57±18.86 µm, P scaling significantly changed the surface integrities of lithium disilicate and zirconia. Surface polishing with multi-step intraoral kit after repeated scaling was only effective for the zirconia, while it was not for lithium disilicate.

Uliasz-Bochenczyk, Alicja; Mokrzycki, Eugeniusz

2007-01-01

Poland is a country where power and heat energy production is based on conventional fuel combustion, above all hard coal and lignite. In power plants and combined heat and power plants, fossil fuel combustion results in emitting to the atmosphere first of all SO 2 , NO x , CO, particulate matter, greenhouse gases for instance N 2 O and CO 2 . For many years the Polish power industry has tried to reduce the emission of air contaminants to the atmosphere. The reduction is feasible on account of various methods of emission reduction, which have been advanced and applied for many years. The paper presents conventional fuels used in the Polish professional power industry, as well as the principal emission types occurring there for the last 10 years and the undertaken reduction measures

Antoszczyszyn, Marek

2017-10-01

The paper discusses a controversy surrounding the latest amendment to the text of the Polish Parliament Act Conservation and the Care of Monuments (2015). It is a common dictum that any edifice cannot exist without good foundations. In this particular case of the mentioned above Act, definition of monument appears to be such a basis. A social interest is one of the constituent elements of the definition mentioned above. In the first part of the paper the notion of the social interest expression has been discussed, particularly from national and international points of view. The second part of the paper comprises some examples from the Polish monument preservation experience with the use of comparison method supported by case study. Only three big Polish cities: Warsaw, Wroclaw and Szczecin are involved in the presented case study but it must be emphasized that many other places on Polish territory experienced the same. Basing on the faith of these cities, the results and discussion chapter proves fundamental discrepancy in social interest notion between national and international scopes using some analytical methods. Finally, in the discussion chapter some proposals for the future amendment of monument definition in the Act of Conservation and the Care of Monuments have been provided.

2013-06-01

Full Text Available Aim of the study: The aim of this study was to estimate some basic data related to the fertility in the chosen groups of Polish and Czech women. We have tried to acquire and analyze the attitudes and beliefs of these women in motherhood and the desire to have children. These data enable to verify the interdisciplinary hypothesis explaining the decline of birth rate and low fertility in European countries. Materials and methods: The authors performed the survey by means of a questionnaire formulated after a comprehensive discussion of possible reasons of birth rate decline. They have tried through the questions of the survey to verify the hypothesis that the decline is the result of the cumulative mental changes occurring in contemporary societies. The questionnaire completed 90 Polish women students pursuing complementary studies of nursing in Higher School of Applied Sciences in Nysa, during the academic year 2012/2013. The questionnaire also completed 53 Czech women students pursuing part-time studies and training at the Tomas Bata University in Zlin (the Czech Republic. Results: The above surveyed 90 Polish women gave birth to 132 children, so fertility rates is 1.46. The average age at the birth of the first child was 24.7 years, of the second child 27.5 and of the third child 31.7 years. The surveyed 53 Czech women gave birth to 86 children, so fertility rates is 1.62. The average age at birth of the first child was 24.7 years, of the second child 27.2 and of the third child 27,5 years. The authors present also convictions, beliefs and attitudes of the women under study. Conclusions: The multifaceted and interdisciplinary hypothesis (theoretical model formulated at the outset of our work, can be useful for attempts to estimate the pro-family attitudes in different populations of women. The results in the light of compliance with the proposed theoretical model allow for the formulation of proposals for action, which would counteract the

1994-04-01

New machining and polishing techniques have been developed for large scintillating crystal arrays such as the Barium Fluoride Electromagnetic Calorimeter for the GEM Detector at SSCL, the Crystal Clear Collaboration's cerium fluoride or lead tungstenate calorimeter at the proposed LHC and CERN, the PHENIX Detector at RHIC (barium fluoride), and the cesium iodide Calorimeter for the BaBar Detector at PEP-2 B Factory at SLAC. The machining and polishing methods to be presented in this paper provide crystalline surfaces without sub-surface damage or deformation as verified by Rutherford Back-scattering (RBS) analysis. Surface roughness of about 10--20 angstroms and sub-micron mechanical tolerances have been demonstrated on large barium fluoride crystal samples. Mass production techniques have also been developed for machining the proper angled surfaces and polishing up to five 50 cm long crystals at one time. These techniques utilize kinematic mount technology developed at LLNL to allow precision machining and polishing of complex surfaces. They will present this technology along with detailed surface studies of barium fluoride and cerium fluoride crystals polished with this technique

The objective of the study was to assess the current status of ethics education in obstetrics-gynecology residency programs. A cross-sectional, web-based survey was designed in conjunction with a professional survey laboratory at the University of Chicago. The survey was piloted with a convenience sample of clinical medical ethics fellows to assess question content and clarity. The survey was deployed by e-mail to all obstetrics-gynecology residency program directors. Descriptive statistics were used to analyze participant responses. The University of Chicago's Institutional Review Board deemed this study exempt from institutional review board formal review. Of 242 eligible obstetrics-gynecology residency program directors, 118 (49%) completed the survey. Most respondents were from university-based programs (n = 78, 66%) that were not religiously affiliated (n = 98, 83%) and trained 4-6 residents per postgraduate year (n = 64, 70%). Although 50% of program directors (n = 60) reported having ethics as part of their core curriculum, most programs teach ethics in an unstructured manner. Fifty-seven percent of respondents (n = 66) stated their program dedicated 5 or fewer hours per year to ethics. The majority of program directors (n = 80, 73%) responded they would like more to a lot more ethics education and believed that ethics education should be required (n = 93, 85%) for residents to complete their training. Respondents identified that crowding in the curriculum was a significant barrier to increased ethics training (n = 50, 45%) and two-thirds (n = 74, 67%) reported a lack of faculty expertise as a moderate barrier to providing ethics education in the residency curriculum. This study found that a lack of structured curricula, inadequate faculty expertise, and limited time were important barriers for ethics education in obstetrics-gynecology programs across the nation. Despite these existing challenges, program directors have a strong interest in increasing ethics

Alawjali, S S; Lui, J L

2013-08-01

This study was to compare the effect of three different one-step polishing systems on the color stability of three different types of nanocomposites after immersion in coffee for one day and seven days and determine which nanocomposite material has the best color stability following polishing with each of the one-step polishing system. The nanocomposites tested were Tetric EvoCeram, Grandio and Herculite Précis. A total of 120 discs (40/nanocomposite, 8mm×2mm) were fabricated. Ten specimens for each nanocomposite cured under Mylar strips served as the control. The other specimens were polished with OptraPol, OneGloss and Occlubrush immersed in coffee (Nescafé) up to seven days. Color measurements were made with a spectrophotometer at baseline and after one and seven days. Two way repeated measure ANOVA, two way ANOVA and Bonferroni tests were used for statistical analyses (P<0.05). The immersion time was a significant factor in the discoloration of the nanocomposites. The effect of three one-step polishing systems on the color stability was also significant. The color change values of the materials cured against Mylar strips were the greatest. The lowest mean color change values were from the Occlubrush polished groups. The effect of the three different types of nanocomposite on the color change was significant. The highest color change values were with Tetric EvoCeram groups. The lowest color change values were with Herculite Précis groups. The color change of nanocomposite resins is affected by the type of composite, polishing procedure and the period of immersion in the staining agent. Copyright © 2012 Elsevier Ltd.

Full text: Rare earth oxide polishes are widely used in the glass industry because of its mechanical and chemical polishing action. The Japanese glass industry use 2000 tons per year of the polishes, and a large portion of them are thrown away after their polishing lifetime. A dry recovery processes for rare earths from the used polishes have been investigated by using a chemical vapor transport method via the formation of vapor complexes RAl n Cl 3+3n (R = rare earths). A flow type reactor with various temperature gradients was employed for the process. The used polishes were mixed with active carbon, and chlorinated with N 2 + Cl 2 mixture at 1273 K. Aluminium oxide were also chlorinated at lower temperature and the resulting AlCl 3 were introduced to the reactor. The rare earth chlorides and AlCl 3 were converted to the vapor complexes. These were driven along the temperature gradient, decomposed according to the reverse reaction, and regenerated RCl 3 . About 90 % of the used polish were chlorinated after 2 hours. Rare earth chlorides, AlCl 3 , and FeCl 3 were fully transported after 82 hours. The rare earth chlorides were mainly condensed over the temperature range 1263-903 K. On the other hand, AlCl 3 and FeCl 3 were deposited at the temperature range below 413 K. CaCl 2 and SrCl 2 were hardly transported and remained in the residue. When the temperature gradient with the smaller slope was used, mutual separation efficiencies among the rare earths was improved. The highest CeCl 3 purity of 80% was obtained in the process

Internet-based support groups for cancer patients have been studied extensively; very few have focused on gynecologic cancer. We pilot-tested a web-based support group for gynecologic cancer patients and assessed women's perceptions of the intervention. Twenty-seven gynecologic cancer patients were randomized to an immediate intervention or a waitlist control group. Women participated in a 12-week, web-based support group focusing on sexuality-related topics. Semi-structured interviews were conducted to investigate the feasibility and efficacy of the intervention. Women reported benefits to participating in the intervention, including receiving support from group members and moderators, increased emotional well-being, improved feelings of body image and sexuality, and comfort in discussing sexuality online. Web-based support groups are both feasible and accepted by gynecologic cancer patients with psychosexual distress. The online format provided women with easy access to the support group and anonymity in discussing psychosexual concerns. Women with gynecologic cancer may benefit from participating in online support groups which provide an environment of relative anonymity to discuss psychosexual concerns.

Full Text Available Ascites is a pathologic accumulation of fluid within the peritoneal cavity, and usually develops as a result of liver disease, congestive heart failure or nephrotic syndrome. Ascites is also a common manifestation of some gynecologic diseases. It is important that health care workers consider gynecologic problems among the potential differential diagnoses in patients presenting with ascites. Various kinds of ovarian diseases, such as epithelial ovarian cancer, benign ovarian fibroma, stromal hyperplasia, ovarian hyperstimulation syndrome, primary peritoneal serous carcinoma, endometriosis and peritoneal tuberculosis, should be kept in mind when women are found to have ascites.

Full Text Available Aim and objectives: To evaluate the effectiveness of one step micro polishers for residual resin removal on fluorosed teeth using scanning electron microscope (SEM. Methods and Material: 55 teeth with mild to moderate fluorosis were selected with five teeth as control. Metal brackets were bonded onto 50 teeth which were divided into 5 groups. The finishing and polishing methods which were tested include tungsten carbide burs (TCB, multistep finishing system (Sof-Lex, one step polishers (PoGo and combination of TCB with multistep and one step polishing systems. After resin removal, all the samples were examined under SEM for assessment of the enamel surface. Results: The enamel surface was closest to untouched enamel in samples finished with the PoGo one step polishers followed by Sof-Lex multistep finishing system. However, they took the longest time to finish. TCB required the shortest time for residual resin removal. Conclusions: All polishing systems produce a certain degree of damage to the enamel surface with the smoothest surface being produced by one step polishers on fluorosed teeth.

Chemical-mechanical polishing of metal and dielectric films for microelectronic applications

Science.gov (United States)

Hegde, Sharath

The demand for smaller, faster devices has led the integrated circuit (IC) industry to continually increase the device density on a chip while simultaneously reducing feature dimensions. Copper interconnects and multilevel metallization (MLM) schemes were introduced to meet some of these challenges. With the employment of MLM in the ultra-large-scale-integrated (ULSI) circuit fabrication technology, repeated planarization of different surface layers with tolerance of a few nanometers is required. Presently, chemical-mechanical planarization (CMP) is the only technique that can meet this requirement. Damascene and shallow trench isolation processes are currently used in conjunction with CMP in the fabrication of multilevel copper interconnects and isolation of devices, respectively, for advanced logic and memory devices. These processes, at some stage, require simultaneous polishing of two different materials using a single slurry that offers high polish rates, high polish selectivity to one material over the other and good post-polish surface finish. Slurries containing one kind of abrasive particles do not meet most of these demands due mainly to the unique physical and chemical properties of each abrasive. However, if a composite particle is formed that takes the advantages of different abrasives while mitigating their disadvantages, the CMP performance of resulting abrasives would be compelling. It is demonstrated that electrostatic interactions between ceria and silica particles at pH 4 can be used to produce composite particles with enhanced functionality. Zeta potential measurement and TEM images used for particle characterization show the presence of such composite particles with smaller shell particles attached onto larger core particles. Slurries containing ceria (core)/silica (shell) and silica (core)/ceria (shell) composite particles when used to polish metal and dielectric films, respectively, yield both enhanced metal and dielectric film removal rates

The achievement of the derived goals for mirror surface quality on the Advanced X-ray Astrophysics Facility (AXAF), Technology Mirror Assembly (TMA) required a combination of state-of-the-art metrology and polishing techniques. In this paper, the authors summarize the derived goals and cover the main facets of the various metrology instruments employed, as well as the philosophy and technique used in the polishing work. In addition, they show how progress was measured against the goals, using the detailed error budget for surface errors and a mathematical model for performance prediction. The metrology instruments represented a considerable advance on the state-of-the-art and fully satisfied the error budget goals for the various surface errors. They were capable of measuring the surface errors over a large range of spatial periods, from low-frequency figure errors to microroughness. The polishing was accomplished with a computer-controlled process, guided by the combined data from various metrology instruments. This process was also tailored to reduce the surface errors over the full range of spatial periods

Cerium is an element of rare earth group which is called lanthanide series. It is found in the ores like monazite and xenotime which are the tailings of tin mines in the south of Thailand. Cerium is used mostly as lens polishing powder besides the applications in other industries. In this study, cerium extracted from monazite ore breakdown by alkaline process was used for the preparation of lens polishing powder. Cerium hydroxide cake from the process was dissolved by hydrochloric acid and precipitated with oxalic acid. The oxalate precipitate then was calcined to oxide powder and its particle size was measured. Precipitation conditions being studied are concentration of feed cerium chloride solution, concentration of oxalic acid used for the precipitation, concentration of sulfuric acid used as precipitation control reagent and the precipitation temperature. It was found that the appropriate precipitation conditions yielded the fine oxide powder with particle size about 12μm. The oxide powder can be ground to the size of 1-3 μm which is suitable for making lens polishing powder

2014-07-01

Full Text Available There has been a rapid, worldwide increase in oilseed rape production that has resulted in enormous intensification of oilseed rape cultivation, leading to tight rotations. This in turn, has caused an accumulation of pests as well as foliar and soil-borne diseases. Recently, clubroot has become one of the biggest concerns of oilseed rape growers. Clubroot is caused by the soil-borne protist Plasmodiophora brassicae Woronin. The pathogen may be present in groundwater, lakes, and irrigation water used in sprinkling systems. It can be easily transmitted from one field to another not only by water, but also by soil particles and dust transmitted by wind and on machinery. The aim of our overall study was to check for P. brassicae infestation of Polish agricultural soils. This paper presents the 2012 results of a study performed along the Polish-Ukrainian border in two provinces: Lublin (Lubelskie Voivodeship and the Carpathian Foothills (Podkarpackie Voivodeship, in south-east Poland. Monitoring was done in 11 counties, including nine rural and two municipal ones. In total, 40 samples were collected, out of which 36 were collected from fields located in rural areas and four from municipal areas, with two per municipal region. Each sample was collected at 8-10 sites per field, using a soil auger. The biotest to detect the presence of P. brassicae was done under greenhouse conditions using seedlings of the susceptible Brassicas: B. rapa ssp. pekinensis and the Polish variety of oilseed rape B. napus cv. Monolit. Susceptible plants grown in heavily infested soils produced galls on their roots. A county was regarded as free from the pathogen, if none of the bait plants became infected. The pathogen was found in three out of 40 fields monitored (7.5% in the Carpathian Foothill region. The fields were located in two rural counties. The pathogen was not found in Lublin province, and was also not detected in any of the municipal counties. The detection with

Full Text Available The bloody conflict which was taking place in South Africa in the years 1899-1902 was followed with a great interest by Polish public opinion. Its greatest part strongly sympathized with the Boer republics. Their burgers were idealized and presented by the Polish press as brave fighters for independence, who dared to stand up against the world empire to defend their rights while Great Britain was attributed full responsibility for the outbreak of the war. For many Poles the Boers personified the general idea of freedom fighters and symbolized all suppressed nations. Their sad fate seemed to be quite similar to the Polish one and this similarity was the main source of sympathy toward defenders of the Transvaal and Free Orange State. Voices of few Polish intellectuals, who called for a more objective and not so emotional view on the war, could not change the pro-Boers stance of the greatest part of Polish public opinion.

The impact of general gender stereotypes on nursing is severe and influential, especially with regard to male nursing students working in obstetrics and gynecology wards. This study examined the experience of male nursing students in obstetrics and gynecology wards. We used a phenomenological qualitative research approach and a sample of 10 male nursing students currently studying at a nursing college in central Taiwan. All participants had obstetrics and gynecology ward experience. Individual interviews were transcribed into the procedural record. Colaizzi content analysis analyzed and categorized research data. Based on participants practical experiences in the obstetrics and gynecology ward, the main stages of participants professional development through their internship experience included: (1) Unbalanced self-role recognition; (2) being defined by the gender framework (gender stereotypes); (3) the difference between male doctor and male nurse; (4) learning appropriate communication techniques; (5) mutual and empathetic understanding of the female psychology during childbirth; (6) gaining sources for positive feedback; (7) releasing the shackles of gender and gaining full insight into and comprehension of nursing functions; and (8) given the opportunity to learn. Through ongoing examination and learning, participant internships in the obstetrics and gynecology wards were significant and essential learning experiences that validated their necessity. Nursing schools and internship institutions alike must realize the importance of gender-equality education to the nursing profession. Medical institutions are encouraged to offer equal learning opportunities to male and female nursing students and provide targeted assistance to males to help them master clinical nursing care practices in the obstetrics and gynecology department.

Full Text Available Oxidation-assisted polishing is an important machining method for obtaining SiC parts with high precision. Through plasma oxidation, thermal oxidation, and anodic oxidation, soft oxide can be obtained on the RS-SiC substrate. With the assistance of abrasive polishing to remove the oxide rapidly, the material removal rate can be increased and the surface quality can be improved. The research results indicate that the surface roughness root-mean-square (RMS and roughness-average (Ra can reach 0.626 nm and 0.480 nm by plasma oxidation-assisted polishing; in thermal oxidation-assisted polishing, the RMS and Ra can be 0.920 nm and 0.726 nm; in anodic oxidation, the calculated oxidation rate is 5.3 nm/s based on Deal-Grove model, and the RMS and Ra are 4.428 nm and 3.453 nm respectively in anodic oxidation-assisted polishing. The oxidation-assisted polishing can be propitious to improve the process level in machining RS-SiC, which would promote the application of SiC parts in optics and ceramics fields.

The purpose of this research was to support the optics finishing development work for the NIF, the National Ignition Facility. One of the major expenses for the construction of NIF is the cost of finishing of the large aperture optics. One way to significantly reduce the cost of the project is to develop processes to reduce the amount of time necessary to polish the more than 3,000 amplifier slabs. These slabs are rectangular with an aspect ratio of more than twenty to one and are made of a very temperature sensitive glass, Nd doped phosphate laser glass. As a result of this effort, we could potentially reduce the time necessary to polish each surface of an amplifier from 20-30 hours of run time to under an hour to achieve the same removal and still maintain a flatness of between one to three waves concave figure. We also feel confident that we can polish rectangular thermally sensitive glass flat by use of temperature control of the polishing platen, pad curvature, slurry concentration with temperature control, pad rotation, and pressure; although further, larger scale experiments are necessary to gain sufficient confidence that such a procedure could be successfully fielded

2008-01-01

A new surface modification for bio-titanium alloy products by electron beam (EB) polishing is proposed. In this EB polishing method, high energy density EB can be irradiated without concentrating the beam. Therefore, large-area EB with a maximum diameter of 60 mm can be used for instantaneously melting or evaporating metal surface. Experimental results made it clear that surface characteristics, such as repellency, corrosion resistance and coefficient of friction could be improved simultaneously with the surface smoothing in a few minutes under a proper condition. Therefore, EB polishing method has a possibility of high efficient surface smoothing and surface modification process for bio-titanium alloy. (author)

Full Text Available Aim/purpose - The main aim of the paper is to fill in the gap in the existing literature as well as to propose a set of specific family enterprises' (FE attributes concerning certain socioeconomic conditions in Poland. The objectives of the article are interrelated with two theses. H1 assumes that in current literature there is a little attention paid to the demand side of the market, particularly to the individual consumers (including young buyers and their attitudes toward FEs. H2 indicates that the perception of Polish FEs changes considerably reflecting the international trends. Design/methodology/approach - The authors studied a consolidated profound review of recent international and Polish publications on FEs. The expert interviews and in-depth individual interviews were conducted. Both empirical studies brought a preliminary insight into overall consumer perception of the FEs in Poland. Findings - For several years Polish buyers have been dynamically changing their mindset, breaking the stereotype of FEs' owners. Nowadays, tradition and quality are two attributes which are associated closely with Polish FEs. Customers indicate that FEs are trustworthy, responsible, solid and dependable. They also highlight the ethnocentric attitude toward these companies - Polishness. All these attributes are evidently appreciated. FEs are correlated with traditional industries and products, especially with groceries, cosmetics, clothes, shoes, jewelry, furniture, windows and doors. Research implications/limitations - The identity of FEs is not always communicated properly. Consumers often cannot ascertain a provenance of their offer as many FEs do not emphasize their family identity. Additionally, on the Polish market, consumers are occasionally misled considering the family ownership of a business. Originality/value/contribution - The studies indicate a set of attributes typical of Polish FEs underpinning their strong identity which should be

Astronomical mirrors are key elements in modern optical telescopes, their dimensions are usually large and their specifications are demanding. Only a limited number of skilled companies respectively institutions around the world are able to master the challenge to polish an individual astronomical mirror, especially in dimensions above one meter. This paper presents an overview on the corresponding market including a listing of polishers around the globe. Therefore valuable information is provided to the astronomical community: Polishers may use the information as a global competitor database, astronomers and project managers may get more transparency on potential suppliers, and suppliers of polishing equipment may learn about unknown potential customers in other parts of the world. An evaluation of the historical market demand on large monolithic astronomical mirrors is presented. It concluded that this is still a niche market with a typical mean rate of 1-2 mirrors per year. Polishing of such mirrors is an enabling technology with impact on the development of technical know-how, public relation, visibility and reputation of the supplier. Within a corresponding technical discussion different polishing technologies are described. In addition it is demonstrated that strategic aspects and political considerations are influencing the selection of the optical finisher.

Deng, Jinqiu; Peng, Xiaoqiang; Hu, Hao; Ge, Kunpeng

2017-10-01

The aluminum mirrors are widely used as important optical components in some vital fields such as astronomical instruments or military installations due to the unique advantages of aluminum alloy. In order to simplify the structure of optical system and improve the performance at the same time, it's a tendency that the optics will be designed to aspherical or other freeform shapes. However, the traditional techniques are falling to have adequate abilities to deal with the increasing demands of aluminum optics. For example, the tool marks leaved on the surface from single point diamond turning (SPDT) has obvious adverse effects to optical system. The deterministic and sub-aperture polishing process has showed the potential to fabricate complex shapes over the few years. But it's still recognized as a problem to polish bare aluminum directly because of its soft surface and active chemical characteristics. Therefore, a combination of magnetorheological finishing (MRF) and small tool polishing (STP) is applied to obtain high performance aluminum optics in this paper. A paraboloid aluminum mirror was polished with this proposed method, and the results showed that the surface texture of the sample is restrained from rms 0.409λ (λ=632.8nm) to rms 0.025λ, and the surface roughness is improved from average Ra 6 7nm to Ra 3 4nm.

Full Text Available Background: Toxic and hazardous heavy metals like arsenic, lead, mercury, zinc, chromium and iron are found in a variety of personal care products, e.g. lipstick, whitening toothpaste, eyeliner and nail color. The nails absorb the pigments of nail polishes and vaporized or soluble metals can easily pass it. The goal of this survey was to assess whether the different colors of nail polishes comply with maximum concentrations of heavy metals in the EPA’s guidelines. Methods: 150 samples of different popular brands of nail polishes in 13 colors (yellow, beige, silver, pink, white, violet, brown, golden, green, black, colorless, red and blue were randomly purchased from beauty shops in Tehran City, Iran, in 2014. Microwave digestion EPA method 3051 was used by a microwave oven to determine the amount of 5 heavy metals; Nickel, Chromium, Lead, Arsenic and Cadmium. One-way ANOVA, Two-way ANOVA, hierarchical cluster, and principal component analyses were applied by Statistica 7.0 software. Results: The concentrations of chrome, lead, nickel and arsenic showed significant differences between the colors (p<0.05. In all studied samples, the level of cadmium was beyond the safe maximum permissible limit (MPS, but no significance difference in the cadmium content was identified. Conclusion: Due to the high concentrations of toxic metals in many brands of nail polishes, meticulous quality control is recommended for these beauty products.

Minimally invasive surgery has been the trend in various specialties and continues to evolve as new technology develops. The development of robotic surgery in gynecology remains in its infancy. The present study reports the first descriptive series of robotic surgery in complicated gynecologic diseases in Taiwan. From March 2009 to February 2011, the records of patients undergoing robotic surgery using the da Vinci Surgical System were reviewed for patient demographics, indications, operative time, hospital stay, conversion to laparotomy, and complications. Sixty cases were reviewed in the present study. Forty-nine patients had benign gynecologic diseases, and 11 patients had malignancies. These robot-assisted laparoscopic procedures include nine hysterectomy, 15 subtotal hysterectomy, 13 myomectomy, eight staging operation, two radical hysterectomy, five ovarian cystectomy, one bilateral salpingo-oophorectomy and myomectomy, two resections of deep pelvic endometriosis, one pelvic adhesiolysis, three sacrocolpopexy and one tuboplasty. Thirty-three patients had prior pelvic surgery, and one had a history of pelvic radiotherapy. Adhesiolysis was necessary in 38 patients to complete the whole operation. Robotic myomectomy was easily accomplished in patients with huge uterus or multiple myomas. The suturing of myometrium or cervical stump after ligation of the uterine arteries minimized the blood loss. In addition, it was much easier to dissect severe pelvic adhesions. The dissection of para-aortic lymph nodes can be easily accomplished. All these surgeries were performed smoothly without ureteral, bladder or bowel injury. The present analyses include various complicated gynecologic conditions, which make the estimation of the effectiveness of robotic surgery in each situation individually not appropriate. However, our experiences do show that robotic surgery is feasible and safe for patients with complicated gynecologic diseases. Copyright © 2012. Published by

The aim of this work was to assess scientific research of master's and doctoral theses and essays in the Department of Obstetrics and Gynecology, Zagazig University, Egypt. All master's and doctoral theses and essays since the foundation of Department of Obstetrics and Gynecology, Zagazig University, Egypt, in 1975 till end of 2012 were reviewed. A total of 703 theses and essays were reviewed. The important topics in the specialty of obstetrics and gynecology were covered and updated. Infertility, in vitro fertilization-embryo transfer (IVF-ET) and related techniques, and polycystic ovarian disease were the most common gynecologic topics (27.2%), followed by gynecologic oncology (18.5%). Preeclampsia was the most common obstetrics topic (18.8%), followed by issues of high-risk pregnancy, fetal growth restriction, and fetal well-being (11.6%). The number of researches that allow the candidates to learn skills was 183 and it was increased from 4.4% of all research in the period 1979-1988 to 33.2% in period 1989-2000 then slightly decreased to 31.2% in period 2001-2012. Ultrasonography was on the top and was present in 99 out of 183 (54.1%) followed by laparoscopy (30, 16.4%), hysteroscopy (25, 13.7%), IVF-ET and related techniques (16, 8.7%) and colposcopy (13, 7.1%) researches. Multi-disciplinary research was decreased by 61.7% in the period 2001-2012. Researches in academic fields were abandoned and in some clinically important areas like preeclampsia were decreased. Scientific research of master's and doctoral theses and essays was comprehensive, updated, and had some autonomy independent of plans. Research which enable the candidate to learn skills were increased on the expense of academic, clinical and multidisciplinary research. It could be recommended that plans for scientific research should be flexible and should leave a space for local departmental views. Proper training of residents during their rotation in these subspecialties may help to revive the lost

Full Text Available The automation of the grinding and polishing process is important to improve the production efficiency of the part surfaces. In this paper, a new compliant flange mounted on the end of the industrial robots for the robotic grinding and polishing force control is developed. With regard to the non-linear and time-varying problem of the contact force, the mathematical model of the new force control system was presented and the fuzzy PID control strategy was used to drive the proposed system. Especially, the air spring and electric proportional valve is studied to establish the model. The simulation results show that the selected control strategy has quick response and good robustness, which satisfies the real-time requirements of the grinding and polishing force control in processing.

Debris buildup on the bracket-wire interface can influence friction. Cleansing brackets with air-powder polishing can affect this process. The aim of this study was to evaluate the frictional force and amount of debris remaining on orthodontic brackets subjected to prophylaxis with air-powder polishing. Frictional force and debris buildup on the surface of 28 premolar brackets were evaluated after orthodontic treatment. In one hemiarch, each bracket was subjected to air-powder polishing (n = 14) for five seconds, while the contralateral hemiarch (n = 14) served as control. Mechanical friction tests were performed and images of the polished bracket surfaces and control surfaces were examined. Wilcoxon test was applied for comparative analysis between hemiarches at p Brackets that had been cleaned with air-powder polishing showed lower friction (median = 1.27 N) when compared to the control surfaces (median = 4.52 N) (p orthodontic brackets with air-powder polishing significantly reduces debris buildup on the bracket surface while decreasing friction levels observed during sliding mechanics.

Analyze the impact of embedding genetic counseling services in gynecologic oncology on clinician referral and patient uptake of cancer genetics services. Data were reviewed for a total of 737 newly diagnosed epithelial ovarian cancer patients seen in gynecologic oncology at a large academic medical center including 401 from 11/2011-7/2014 (a time when cancer genetics services were provided as an off-site consultation). These data were compared to data from 8/2014-9/2016 (n=336), when the model changed to the genetics embedded model (GEM), incorporating a cancer genetic counselor on-site in the gynecologic oncology clinic. A statistically significant difference in proportion of patients referred pre- and post-GEM was observed (21% vs. 44%, pgenetics consultation and post-GEM 82% were scheduled (pgenetics was also statistically significant (3.92months pre-GEM vs. 0.79months post-GEM, pgenetics consultation (2.52months pre-GEM vs. 1.67months post-GEM, pgenetic counselor on the same day as the referral. Providing cancer genetics services on-site in gynecologic oncology and modifying the process by which patients are referred and scheduled significantly increases referral to cancer genetics and timely completion of genetics consultation, improving compliance with guideline-based care. Practice changes are critical given the impact of genetic test results on treatment and familial cancer risks. Copyright © 2017 Elsevier Inc. All rights reserved.

The methods of painless childbirth are generally divided into two kinds: "with drugs" and "without drugs." In Japan, the full-scale initiation of these two types of painless childbirth methods in clinical practice started in the early 1950s. The practice of the psychoprophylaxis method (PPM)--one of the painless childbirth methods "without drugs"--started in 1953. Japanese obstetricians had discussed the practicability of PPM for painless childbirth and had doubted the scientific nature and originality of PPM as a viable method. Therefore, they published a series of articles in the Japanese medical journal "Obstetrics and Gynecology" from 1954 to 1957. Two representative obstetricians developed this controversy. Naotaro KUJI, the director of the Central Maternity Hospital of the Japanese Red Cross Society and the chief practitioner of PPM, emphasized that PPM was a more practical method, considering the Japanese medical legal situation where midwives were prohibited to use drugs. On the other hand, Kakuichi ANDO, the chief professor of the Department of Obstetrics and Gynecology of Keio University and the team leader of the practitioners of painless childbirth "with drugs," doubted the practicability of PPM. In the course of these discussions, both groups of obstetricians gradually came to a consensus to use the concept of "pain relief" in labor, instead of "painless" childbirth. They also agreed to adopt methods "with drugs" and "without drugs," including PPM, according to the presented case.

The aim of this study is to evaluate the usefulness of diffusion-weighted (DW) magnetic resonance (MR) imaging in detecting peritoneal dissemination in cases of gynecological malignancy. We retrospectively analyzed MR images obtained from 26 consecutive patients with gynecological malignancy. Peritoneal dissemination was histologically diagnosed in 15 of the 26 patients after surgery. We obtained DW images and half-Fourier single-shot turbo-spin-echo images in the abdomen and pelvis, and then generated fusion images. Coronal maximum-intensity-projection images were reconstructed from the axial source images. Reader interpretations were compared with the laparotomy findings in the surgical records. Receiver-operating characteristic (ROC) curves were used to represent the presence of peritoneal dissemination. In addition, the sensitivity and specificity were calculated. DW imaging depicted the tumors in 14 of 15 patients with peritoneal dissemination as abnormal signal intensity. ROC analysis yielded Az values of 0.974 and 0.932 for the two reviewers. The mean sensitivity and specificity were 90 and 95.5%. DW imaging plays an important role in the diagnosis and therapeutic management of patients with gynecological malignancy. (orig.)

Full Text Available The aim of the present study was to investigate the factor structure and psychometric properties of the Polish adaptation of Romantic Beliefs Scale (RBS; Sprecher & Metts, 1989. In a sample of 414 Polish university students aged 19-25 (227 females and 187 males, the factor structure of the original English version was confirmed for the four subscales: Love Finds a Way, One and Only, Idealization, and Love at First Sight. The present study provides evidence that the 15-item version of the Polish adaptation of the (RBS possesses a factor structure and psychometric properties comparable to the English-language version of RBS. It was shown to be a reliable self-report measure for romantic beliefs within a sample of the Polish population. The development of a new Polish measure of romantic beliefs has provided further validation for the RBS, and provided evidence in support of the ideology of romanticism in various populations, and indicated the importance of differentiating between the different types of romantic beliefs.

To compare the surface roughness of nanofilled dental composite resin and microhybrid composite resins after curing and polishing. A nanofilled composite (Z350) and 4 microhybrid composites (P60, Z250, Spectrum, and AP-X) were fabricated from the lateral to the medial layers to prepare 8 mm×8 mm×5 mm cubical specimens. The 4 lateral surfaces of each specimens were polished with abrasive disks (Super-Snap). Profilometer was used to test the mean surface roughness (Ra) after polishing. P60 had the lowest Ra (0.125∓0.030 µm) followed by Z250 and Spectrum. The Ra of Z350 (0.205∓0.052 µm) was greater than that of the other 3 resins, and AP-X had the roughest surfaces. Under scanning electron microscope, the polished faces of P60 resin were characterized by minor, evenly distributed particles with fewer scratches; the polished faces of Z350 presented with scratches where defects of the filling material could be seen. The nanofilled composite Z350 has smooth surface after polishing by abrasive disks, but its smoothness remains inferior to that of other micro-hybrid composite resins.

Improved energy efficiency and reduced cost are greatly desired for advanced particle accelerators. Progress toward both can be made by atomically-smoothing the interior surface of the niobium superconducting radiofrequency accelerator cavities at the machine's heart. Laser polishing offers a green alternative to the present aggressive chemical processes. We found parameters suitable for polishing niobium in all surface states expected for cavity production. As a result, careful measurement of the resulting surface chemistry revealed a modest thinning of the surface oxide layer, but no contamination.

The 3-D surface morphology was investigated by atomic force microscopy (AFM) and multifractal analysis. Two representative dental resin-based nanocomposites were investigated: a nanofilled and a nanohybrid composite. The samples were polished by two dental polishing protocols using multi-step and one-step system. Both protocols were then followed by diamond paste polishing.

The multifractal spectrum theory based on computational algorithms was applied for AFM data and multifractal spectra were calculated. The generalized dimension D{sub q} and the singularity spectrum f(α) provided quantitative values that characterize the local scale properties of dental nanocomposites polished by four different dental polishing protocols at nanometer scale. The results showed that the larger the spectrum width Δα (Δα = α{sub max} − α{sub min}) of the multifractal spectra f(α), the more non-uniform was the surface morphology. Also, the 3-D surface topography was described by statistical parameters, according to ISO 25178-2:2012. The 3-D surface of samples had a multifractal nature.

Full Text Available Background The aim of this article is to present research on the validity and reliability of the Collective Self-Esteem Scale (CSES for the Polish population. The CSES is a measure of individual differences in collective self-esteem, understood as the global evaluation of one’s own social (collective identity. Participants and procedure Participants from two samples (n = 466 and n = 1,009 completed a paper-pencil set of questionnaires which contained the CSES and the Rosenberg Self-Esteem Scale (RSES, and subsets of participants completed scales related to a sense of belonging, well-being and psychological distress (anxiety and depression. Results Like the original version, the Polish version of the CSES comprises 16 items which form the four dimensions of collective self-esteem: Public collective self-esteem, Private collective self-esteem, Membership esteem and Importance of Identity. The results confirm the four-factor structure of the Polish version of the CSES, support the whole Polish version of the CSES as well as its subscales, which represent satisfactory reliability and stability, and provide initial evidence of construct validity. Conclusions As the results of the study indicate, the Polish version of the CSES is a valid and reliable self-report measure for assessing the global self-esteem derived from membership of a group and has proved to be useful in the Polish context.

Uterine gas gangrene caused by Clostridium perfringens is a serious, often life-threatening infection that is rarely encountered in the practice of gynecologic oncology. However, the hypoxic nature of gynecologic cancers due to necrosis and/or prior radiation therapy creates a microenvironment optimal for proliferation of anaerobic bacteria such as the Clostridium species. Early recognition and aggressive treatment with IV antibiotics and surgical debridement remain the cornerstones of management in order to decrease morbidity and mortality. Here we present the case of a 52 year-old woman with a remote history of cervical cancer who was previously treated at our institution with primary chemotherapy and radiation and was then admitted decades later with Clostridium perfringens bacteremia and CT evidence of intrauterine abscess. The patient received a prolonged course of IV antibiotic therapy and subsequently underwent definitive surgical management with a total abdominal hysterectomy, bilateral salpingo-oophorectomy, small bowel resection with anastomosis for a utero-ileal fistula identified intraoperatively. Pathology from the uterine specimen demonstrated a primary poorly differentiated uterine adenocarcinoma. The patient recovered fully from her Clostridium perfringens infection and was discharged from the hospital shortly after surgical intervention.
