    Abstract In the United States, intimate partner violence (IPV) against women disproportionately affects ethnic minorities. Further, disparities related to socioeconomic and foreign-born status impact the adverse physical and mental health outcomes as a result of IPV, further exacerbating these health consequences. This article reviews 36 U.S. studies on the physical (e.g., multiple injuries, disordered eating patterns), mental (e.g., depression, post-traumatic stress disorder), and sexual and reproductive health conditions (e.g., HIV/STIs, unintended pregnancy) resulting from IPV victimization among ethnic minority (i.e., Black/African American, Hispanic/Latina, Native American/Alaska Native, Asian American) women, some of whom are immigrants. Most studies either did not have a sufficient sample size of ethnic minority women or did not use adequate statistical techniques to examine differences among different racial/ethnic groups. Few studies focused on Native American/Alaska Native and immigrant ethnic minority women and many of the intra-ethnic group studies have confounded race/ethnicity with income and other social determinants of health. Nonetheless, of the available data, there is evidence of health inequities associated with both minority ethnicity and IPV. To appropriately respond to the health needs of these groups of women, it is necessary to consider social, cultural, structural, and political barriers (e.g., medical mistrust, historical racism and trauma, perceived discrimination, immigration status) to patient–provider communication and help-seeking behaviors related to IPV, which can influence health outcomes. This comprehensive approach will mitigate the racial/ethnic and socioeconomic disparities related to IPV and associated health outcomes and behaviors. PMID:25551432

    Objective Since the 1980s, older low-educated White women experienced an unprecedented decrease in life expectancy. We investigated whether a similar phenomenon was evident among younger women for obesity. Design and Methods Using the National Health and Nutrition Examination Survey, we estimated age-adjusted changes in prevalence of overall and abdominal obesity (BMI≥30 kg/m2, waist circumference>88 cm) between 1988-1994 and 2003-2010 among non-Hispanic White women aged 25-44 years, stratified by educational attainment (women's changes in obesity prevalence to changes among similarly educated Black women. Results Relative increases in overall obesity were disproportionately larger for low- educated (women: 12.3 (95% CI: 3.1, 21.5) percentage points (ppts). For overall and abdominal obesity, general trends indicated dissimilar racial differences by educational attainment. For instance, overall obesity increased more in Blacks than Whites among college-educated (9.9 ppts) but not low- educated (−2.5 ppts) women. Conclusions Contemporary young, low-educated White women showed indications of disproportionate worsening of overall obesity prevalence compared to more educated White and similarly educated Black women. Low education levels are more powerful indicators of obesity risk among contemporary White women than 30 years ago. PMID:25294582

    Maternal and childhood obesity in pregnancy are worrisome public health issues facing our world today. New gene sequencing methods have advanced our knowledge of the disruptive effect of birth interventions and postnatal exposures on the maturation of gut microbiota and immunity during infancy. Yet, little is known about the impact of maternal pregnancy overweight on gut microbes and related processes, and how this may affect overweight risk in offspring. To address this gap in knowledge, we surveyed human studies for evidence in children, infants and pregnant women to piece together the limited literature and generate hypotheses for future investigation. From this literature, we learned that higher Lactobacillus yet lower Bacteroides spp. colonization of gut microbiota within 3 months of birth predicted risk for infant and child overweight. The abundance of bifidobacteria and staphylococci also appeared to play a role in the association with overweight, as did infant fecal immunoglobulin A levels, glycoproteins of the gut immune system that are acquired from breast milk and produced by the infant. We proposed that pregnancy overweight influences the compositional structure of gut microbiota in infants through vertical transfer of microbiota and/or their metabolites during pregnancy, delivery and breastfeeding. Finally, we brought forward emerging evidence on sex dimorphism, as well as ethnic and geographic variation, in reported associations between maternal overweight-induced gut microbiota dysbiosis and overweight risk.

    This study’s purpose was to explore the reasons Black women are disproportionately single according to the unique viewpoint of married Black men. The sample comprised 52 married Black men who resided in northeast Georgia (mean age = 43). Qualitative interviews were conducted in 2010 as part of the Pathways to Marriage study. The authors analyzed the data in a collaborative fashion and utilized content analyses to explore the relationships in the data which were derived from qualitative interviews with the men. Findings on the reasons for the disproportionality of singlehood among Black women reflected these four themes: gender relations, marriage education and socialization, individual development, and a preference for gay/lesbian relationships. Recommendations for future research are discussed. PMID:26082674

    The vulnerability of the urban poor to the recent food and fuel price crisis has been widely acknowledged. The unfolding global financial crisis, which brings higher unemployment and underemployment, is likely to further intensify this vulnerability. This paper reviews the evidence concerning the disproportionate vulnerability of the urban compared with the rural poor to these types of shocks. It reviews some of the unique characteristics of urban life that could make the urban poor particularly susceptible to price and financial shocks and summarizes the evidence regarding the disproportionate vulnerability of the urban poor. The focus is on impacts on poverty, food insecurity, and malnutrition. The review shows that although the urban poor are clearly one of the population groups most affected by the current (and previous) crises, the rural poor, landless, and net buyers are in no better position to confront the crisis without significant suffering. The poorest of the poor are the ones who will be most affected, irrespective of the continent, country, or urban or rural area where they live. The magnitude and severity of their suffering depends on their ability to adapt and on the specific nature, extent, and duration of the coping strategies they adopt. A better understanding of how these coping strategies are used and staggered is critical to help design triggers for action that can prevent households from moving to more desperate measures. Using these early coping strategies as early warning indicators could help prevent dramatic losses in welfare. PMID:19939990

    Background Medicaid Disproportionate Share Hospital (DSH) payments are one of the major sources of financial support for hospitals providing care to low-income patients. However, Medicaid DSH payments will be redirected from hospitals to subsidize individual health insurance purchase through US national health reform. Objectives The purpose of this study is to examine the association between Medicaid DSH payment reductions and nursing-sensitive and birth-related quality of care among Medicaid/uninsured and privately insured patients. Research Design and Method Economic theory of hospital behavior was used as a conceptual framework, and longitudinal data for California hospitals for 1996–2003 were examined. Hospital fixed effects regression models were estimated. The unit of analysis is at the hospital-level, examining two aggregated measures based on the payer category of discharged patients (i.e., Medicaid/uninsured and privately insured). Principal Findings The overall study findings provide at best weak evidence of an association between net Medicaid DSH payments and hospital quality of care for either Medicaid/uninsured or the privately insured patients. The magnitudes of the effects are small and only a few have significant DSH effects. Conclusions Although this study does not find evidence suggesting that reducing Medicaid DSH payments had a strong negative impact on hospital quality of care for Medicaid/uninsured or privately insured patients, the results are not necessarily predictive of the impact national health care reform will have. Research is necessary to monitor hospital quality of care as this reform is implemented. PMID:24714580

  7. Physician-assisted suicide and euthanasia: disproportionate prevalence of women among Kevorkian's patients.

    End-of-life decisions are among the most difficult to make or study. When we examined these decisions made under the auspices and protection of stringent state laws, we found no gender bias among patients who chose to end their lives in the face of documented debilitating and terminal diseases. However, in the case of euthanasia as practiced by Jack Kevorkian, we found significant statistical bias against women. Moreover, other data have questioned whether all of Kevorkian's patients did, in fact, have debilitating and terminal illnesses. In this article, we explore why a gender disparity exists in end-of-life decision making. We conclude that if physician-assisted suicide and euthanasia are to be integrated into any end-of-life medical care policy, stringent legal and medical safeguards will be required. Institution of these safeguards should prevent selection bias in a vulnerable population hastening death for reasons other than medically justifiable conditions or issues of individual autonomy, and should ensure that end-of-life decisions are truly reflective of competent personal choice, free from economic considerations or societal pressure.

    Bacterial disproportionation of elemental sulfur (S0) is a well-studied metabolism and is not previously reported to occur at pH values less than 4.5. In this study, a sediment core from an abandoned-coal-mine-waste deposit in Southwest Indiana revealed sulfur isotope fractionations between S0 and pyrite (Δ34Ses-py) of up to -35‰, inferred to indicate intense recycling of S0 via bacterial disproportionation and sulfide oxidation. Additionally, the chemistry of seasonally collected pore-water profiles were found to vary, with pore-water pH ranging from 2.2 to 3.8 and observed seasonal redox shifts expressed as abrupt transitions from Fe(III) to Fe(II) dominated conditions, often controlled by fluctuating water table depths. S0 is a common product during the oxidation of pyrite, a process known to generate acidic waters during weathering and production of acid mine drainage. The H2S product of S0 disproportionation, fractionated by up to -8.6‰, is rapidly oxidized to S0 near redox gradients via reaction with Fe(III) allowing for the accumulation of isotopically light S0 that can then become subject to further sulfur disproportionation. A mass-balance model for S0 incorporating pyrite oxidation, S0 disproportionation, and S0 oxidation readily explains the range of observed Δ34Ses-py and emphasizes the necessity of seasonally varying pyrite weathering and metabolic rates, as indicated by the pore water chemistry. The findings of this research suggest that S0 disproportionation is potentially a common microbial process at a pH < 4.5 and can create large sulfur isotope fractionations, even in the absence of sulfate reduction.

  10. Considerations in HIV Prevention for Women Affected by the Criminal Justice System

    2011-01-01

    Within the national dialogue of HIV prevention strategies, relatively little consideration is given to the millions of women and girls affected by the criminal justice system either through their own incarceration or that of their partners. Yet statistics indicate that these women and girls are disproportionately infected or at risk for HIV and other sexually transmitted infections and much of this risk is directly related to the dynamics and circumstances that led to their incarceration or relationships with incarcerated men. As we look for the link between public health and correctional health within our National HIV/AIDS Strategy, it is imperative that the risks, obstacles, and opportunities facing women and girls affected by incarceration are brought into the discussion. Gender responsive HIV prevention policies and practices must be developed to address the unique risks and opportunities for these women and girls. This paper presents data on HIV risk and other health issues specific to this community of women and girls, discusses key factors for consideration when developing gender-responsive HIV strategies for these communities, and makes recommendations for inclusion in the National HIV/AIDS Strategy and other state and local HIV prevention efforts.

    Charge disproportionation (CD) recently observed in many organic conductors is reviewed. CD is closely related to the charge ordering (CO) but is observed even when no long range CO is established. In a ? -phase BEDT-TTF salt, (BEDT-TTF){2}RbZn(SCN){4}, an extremely slow dynamics of CD has been observed above T_MI. A similar phenomenon is also observed in the Cs-analog, (BEDT-TTF){2}CsZn(SCN){4}. However, a spin-singlet ground state without CD is suggested in this salt at low temperatures. It is shown that ? -(BETS){2}I{3} exhibits CD at low temperatures, as in ? -(BET-TTF){2}I{3}. Recently, an abnormal line broadening has been observed in 13C-NMR of (TMTSF){2}FSO{3} under pressure as well as in 77Se-NMR of ?-(BETS){2}FeCl{4} in a high field. We expect that both are very likely caused by a large CD among the organic molecular sites. The current investigation is a part of a Grant-in-Aid for Scientific Research on Priority Areas of Molecular Conductors (No. 15073221) from the Ministry of Education, Culture, Sports, Science and Technology, Japan, and the Japan-Korea Joint Research Project from Japan Society for the Promotion of Science (03-01-8) and Korea Science and Engineering Foundation (F01-2003-000-20023-0).

    Objective Endometrial cancer mortality disproportionately affects black women and whether greater prevalence of obesity plays a role in this disparity is unknown. We examine the effect of race on post-surgical complications, length of stay, and mortality specifically in a morbidly obese population. Methods Black and white women with endometrial cancer diagnosed from 1996 to 2012 were identified from the University Pathology Group database in Detroit, Michigan, and records were retrospectively reviewed to obtain clinicopathological, demographic, and surgical information. Analysis was limited to those with a body mass index of 40 kg/m2 or greater. Differences in the distribution of variables by race were assessed by chi-squared tests and t-tests. Kaplan–Meier and Cox regression analyses were performed to examine factors associated with mortality. Results 97 white and 89 black morbidly obese women were included in this analysis. Black women were more likely to have type II tumors (33.7% versus 15.5% of white women, p-value= 0.003). Hypertension was more prevalent in black women (76.4% versus 58.8%, p-value = 0.009), and they had longer hospital stays after surgery despite similar rates of open vs minimally invasive procedures and lymph node dissection (mean days = 5.4) compared to whites (mean days = 3.5, p-value = 0.036). Wound infection was the most common complication (16.5% in whites and 14.4% in blacks, p-value = 0.888). Blacks were more likely to suffer other complications, but overall the proportions did not differ by race. In univariate analyses, black women had higher risk of endometrial cancer-related death (p-value = 0.090). No racial differences were noted in adjusted survival analyses. Conclusion Amore complete investigation, incorporating socio-demographic factors, is warranted to understand the effects of morbid obesity and race on endometrial cancer. PMID:24680590

  13. Disproportionate minority contact.

    PubMed

    Piquero, Alex R

    2008-01-01

    For many years, notes Alex Piquero, youth of color have been overrepresented at every stage of the U.S. juvenile justice system. As with racial disparities in a wide variety of social indicators, the causes of these disparities are not immediately apparent. Some analysts attribute the disparities to "differential involvement"--that is, to differences in offending by minorities and whites. Others attribute them to "differential selection"--that is, to the fact that the justice system treats minority and white offenders in different ways. Still others believe the explanation lies in a combination of the two. Differential involvement may be important earlier in the judicial process, especially in youths' contacts with police, and may influence differential selection later as individuals make their way through the juvenile justice system. Adjudicating between these options, says Piquero, is difficult and may even be impossible. Asking how much minority overrepresentation is due to differences in offending and how much to differences in processing no longer seems a helpful way to frame the discussion. Piquero urges future research to move beyond the debate over "which one matters more" and seek to understand how each of the two hypotheses can explain both the fact of minority overrepresentation in the juvenile justice system and how best to address it. Piquero cites many sizable gaps in the research and policy-relevant literature. Work is needed especially, he says, in analyzing the first stage of the justice system that juveniles confront: police contacts. The police are a critical part of the juvenile justice decision-making system and are afforded far more discretion than any other formal agent of social control, but researchers have paid surprisingly little attention to contacts between police and citizens, especially juveniles. Piquero notes that some states and localities are undertaking initiatives to reduce racial and ethnic disparities. He urges researchers and policymakers to evaluate such initiatives, especially those using strategies with a track record of success. Researchers should also examine empirically the far-reaching consequences of disproportionate minority representation in the juvenile justice system, such as poor outcomes in education, labor force participation, and family formation. Finally, Piquero emphasizes that one critical research area involves updating justice system data systems and repositories, which have failed to track changes in U.S. demographic and immigration patterns.

    We propose that women regularly anticipate and receive messages from others that trivialize the severity of their body image concerns. Moreover, we suggest that these minimizing messages can heighten women's negative affective reactions to body image threats, particularly if they internalize them. Two studies provided support for these ideas. In…

  15. Microvascular angina: angina that predominantly affects women

    Park, Jin Joo; Choi, Dong-Ju

    2015-01-01

    In women receiving evaluation for suspected ischemic symptoms, a "normal" diagnosis is five times more common than it is in men. These women are often labeled as having cardiac syndrome X, also known as microvascular angina (MVA). MVA is defined as angina pectoris caused by abnormalities of the small coronary arteries, and is characterized by effort chest pain and evidence of myocardial ischemia with a non-invasive stress test, although the coronary arteries can appear normal or near normal by angiography. MVA patients are often neglected due to the assumption of a good prognosis. However, MVA has important prognostic implications and a proper diagnosis is necessary in order to relieve the patients' symptoms and improve clinical outcomes. The coronary microvasculature cannot be directly imaged using coronary angiography, due to the small diameter of the vessels; therefore, the coronary microvascular must be assessed functionally. Treatment of MVA initially includes standard anti-ischemic drugs (?-blockers, calcium antagonists, and nitrates), although control of symptoms is often insufficient. In this review, we discuss the pathophysiology, diagnosis, and treatment of MVA. PMID:25750553

    Study objectives: Evaluate the prevalence and phenomenology of dream-associated behaviors affecting pregnant and postpartum mothers. Episodes consist of anxious dreams and nightmares about the new infant that are accompanied by complex behaviors (motor activity, speaking, expressing emotion). Design: Three-group design (postpartum, pregnant, null gravida), self-report, and repeated measures. Setting: Pregnancy and postpartum groups: completion of questionnaires in hospital room within 48 hours of giving birth and home telephone interviews; null gravida group: completion of questionnaires and interview in person or by telephone. Participants: Two hundred seventy-three women in 3 groups: postpartum: n = 202 (mean age = 29.7 ± 4.94 years; 95 primiparas, 107 multiparas); pregnant: n = 50 (mean age = 31.1 ± 5.44 years); null gravida: n = 21 (mean age = 28.5 ± 6.34 years). Interventions: Subjects completed questionnaires about pregnancy and birth factors, personality, and sleep and participated in interviews concerning the prevalence of recent infant dreams and nightmares, associated behaviors, anxiety, depression, and other psychopathologic factors. Measurements and Results: Most women in all groups recalled dreams (88%-91%). Postpartum and pregnant women recalled infant dreams and nightmares with equal prevalence, but more postpartum women reported they contained anxiety (75%) and the infant in peril (73%) than did pregnant women (59%, P < 0.05 and 42%, P < 0.0001). More postpartum (63%) than pregnant (40%) women reported dream-associated behaviors (P < 0.01), but neither group differed from null gravida women (56%). This was due to different distributions over groups of the behavior subtypes. Motor activity was present in twice as many postpartum (57%) as pregnant (24%) or null gravida (25%) women (all P < 0.0001). Expressing emotion was more prevalent among null gravida (56%) than postpartum women (27%) (P < 0.05) but was not different from pregnant women (37%). Speaking was equally prevalent among the 3 groups (12%-19%). Behaviors were associated with nightmares, dream anxiety and, among postpartum women, post-awakening anxiety (41%), confusion (51%), and a need to check on the infant (60%). Primiparas and multiparas differed in dream and nightmare recall but not in prevalence of dream-associated behaviors. Conclusion: The prevalent occurrence of pregnancy and postpartum infant dreams and associated behaviors may reflect the pervasive emotional influence of maternal concerns or changes instigated by severe sleep disruption, rapid eye movement sleep deprivation, and altered hormone levels.

    2014-10-01

    The affective decision making of 41 recently treated outpatient women with borderline personality disorder (BPD) was compared to 41 healthy controls using the Iowa Gambling Task (IGT). Non-affective executive functions (EF) of working memory, interference control, and motor inhibition were also compared. Associations among affective and non-affective EF were examined. Despite normal range intelligence, Stroop interference, motor inhibition, and working memory, women with BPD made significantly more disadvantageous IGT decisions than controls (Cohen's d = .72) that were unrelated to substance abuse history, education, psychotropic use, or attentional deficits. Correlates of EF and IGT performance varied by group. Intellect, BPD, and intact behavioral control explained 35% of the adjusted variance in net IGT performance. Disadvantageous IGT decision making was the only EF to predict BPD. IGT deficits in BPD may be separable from IQ and other EF as supported by the somatic marker hypothesis and suggest a stable, trait-like vulnerability favoring immediate reward over long-term gain in women with the disorder.

    Polycystic ovary (PCO) syndrome is biochemically characterized by abnormal gonadotropin secretion and polycystic ovaries associated with increase in size and functional activity of stromal tissue; multifollicular ovaries (MFO) are defined by the presence of multiple cysts with no increase in stromal tissue. A central (hypothalamic-pituitary) abnormality, including high plasma beta-endorphin (BE) concentrations without simultaneous elevation of ACTH, was reported for subjects with PCO syndrome. Since we have found the presence of high plasma BE concentrations in hereditary angioedema (HANE) during attacks as well as during symptom-free periods, we studied, by means of pelvic ultrasound scanning employed to determine the prevalence of PCO and of MFO, 13 women of reproductive age affected with HANE who were not on oral contraceptives. We have found PCO in 5/13 (38.4%) and MFO in 7/13 (53.8%) HANE patients. Nine patients had oligomenorrhoea (five with PCO, three with MFO, one with normal ovaries), five (three with PCO, two with MFO) were hirsute and only one (with MFO) had weight loss. No patient was obese. Mean plasma LH, testosterone, prolactin, cortisol and ACTH concentrations were normal, while FSH was significantly reduced and LH/FSH ratio increased. BE concentrations were significantly high in all the patients studied. Our results clearly demonstrate that women with HANE frequently have cystic ovaries (polycystic or multifollicular) in the presence of high BE concentrations. PMID:1333923

    Males comprised 66 percent of wild wolf (Canis lupus) pups from a saturated, high-density wolf range in northeastern Minnesota, possibly reflecting disproportionate conception of males. Packs from areas of lower wolf density in other areas of Minnesota had equal sex ratios of pups or a disproportionate number of female pups. Captive wolves showed a slight preponderance of male pups.

    2010-08-01

    This study evaluated the effects of a sexual victimization history, trait disinhibition, alcohol use history, number of lifetime sexual partners, and the contextual features of dating and social events (i.e., sexual activity and alcohol use) on women's response choices to a set of vignettes describing diverse social situations. A total of 170 undergraduate women chose one of six responses to each situation that varied in their degree of response refusal. Averaged across the situations, more severely victimized women and women reporting higher disinhibition chose responses lower in refusal than nonvictimized women and women reporting lower disinhibition. Past victimization, disinhibition, and number of sexual partners also moderated the influence of the situations' contextual features on women's response refusal. Specifically, as the presence of sexual activity increased in the situations, the response refusal of more severely victimized women increased less than nonvictimized women. In addition, as the presence of alcohol increased in the situations, the response refusal of women reporting higher disinhibition and a greater number of sexual partners decreased more than women reporting lower disinhibition and a fewer number of sexual partners.

  4. Has ADVANCE Affected Senior Compared to Junior Women Scientists Differently?

    2015-01-01

    Substantial evidence exists to demonstrate that the NSF ADVANCE Inititiative has made a positive impact upon institutions. Since it began in 2001, ADVANCE has changed the conversation, policies, and practices in ways to remove obstacles and systemic barriers preventing success for academic women scientists and engineers. Results from ADVANCE projects on campuses have facilitated consensus nationally about policies and practices that institutions may implement to help to alleviate issues, particularly for junior women scientists.Although getting women into senior and leadership positions in STEM constituted an initial impetus for ADVANCE, less emphasis was placed upon the needs of senior women scientists. Surveys of academic women scientists indicate that the issues faced by junior and senior women scientists differ significantly. The focus of ADVANCE on junior women in many ways seemed appropriate--the senior cohort of women scinetists is fed by the junior cohort of scientists; senior women serve as mentors, role models, and leaders for the junior colleagues, while continuing to struggle to achieve full status in the profession. This presentation will center on the differences in issues faced by senior compared to junior women scientists to explore whether a next step for ADVANCE should be to address needs of senior academic women scientists.

    In this paper we compare the mental health of women who reported domestic violence and women who reported no abuse in their lifetime. A longitudinal study was conducted with women, 16 to 74 years (n = 358), who attended the emergency department of a major public hospital in Australia. Our aim was to investigate the nature of symptoms and pattern of mental illness associated with domestic violence. The results of the baseline data reported in this paper showed that women who experienced abuse as adults suffered more ill-effects to their mental health than women who did not experience such abuse; also that women who experienced both adult and child abuse suffered more ill-effects than women who experienced abuse either as an adult or child.

    Growing evidence suggests that the ability to control behavior is enhanced in contexts in which errors are more frequent. Here we investigated whether pairing desirable food with errors could decrease impulsive choice during hypothetical temporal decisions about food. To this end, healthy women performed a Stop-signal task in which one food cue predicted high-error rate, and another food cue predicted low-error rate. Afterwards, we measured participants’ intertemporal preferences during decisions between smaller-immediate and larger-delayed amounts of food. We expected reduced sensitivity to smaller-immediate amounts of food associated with high-error rate. Moreover, taking into account that deprivational states affect sensitivity for food, we controlled for participants’ hunger. Results showed that pairing food with high-error likelihood decreased temporal discounting. This effect was modulated by hunger, indicating that, the lower the hunger level, the more participants showed reduced impulsive preference for the food previously associated with a high number of errors as compared with the other food. These findings reveal that errors, which are motivationally salient events that recruit cognitive control and drive avoidance learning against error-prone behavior, are effective in reducing impulsive choice for edible outcomes.

    Context: Various studies have shown that quality of life in women after menopause undergoes radical changes. Several factors such as psycho-social factors are associated with the quality of life during menopausal period. Aims: The present study surveyed the factors associated with quality of life of postmenopausal women in Isfahan, based on Behavioral Analysis Phase of PRECEDE model. Settings and Design: This cross-sectional study was conducted through stratified random sampling among 200 healthy postmenopausal women in Isfahan in 2011. Subjects and Methods: Data were collected by two valid and reliable questionnaires (one to assess the quality of life and the other to survey the factors associated with the Behavioral Analysis Phase of PRECEDE model). Data analysis was performed using SPSS software (version 18) and analytical and descriptive statistics. Results: Pearson correlation indicated a positive and significant correlation between the quality of life and attitude toward menopause, perceived self-efficacy, and enabling and reinforcing factors, but there was no significant relationship between the quality of life and knowledge about menopause. Also, the quality of life in postmenopausal women had significant correlation with their age, education level, marital status, and employment status. Conclusion: Based on the present study, attitude, perceived self-efficacy, perceived social support, and enabling factors are associated with the quality of life in postmenopausal women. So, attention to these issues is essential for better health planning of women. PMID:24520556

    Effects of changes in iron (Fe) and zinc (Zn) status on cognition of premenopausal women were studied. Research in animals and humans shows that Fe and Zn influence brain function. Effects of mild Fe or Zn deficiencies on cognition of women have received limited attention. Therefore, using a double-blind randomized controlled treatment design the authors supplemented 34 sideropenic non-anemic women, ages 18-40 years, with micronutrients plus Fe, Zn, Fe+Zn, or micronutrients only. The micronutrient supplement was based on NRC guidelines. Eleven nonsideropenic women were also given the micronutrient supplement. Subjects were examined with the Weschler Memory Quotient (MQ) and Booklets Categories (BC) tests before and after treatment. After 8 weeks, significant improvement in MQ was displayed by the Fe, Zn and Fe+Zn groups, but no improvement occurred in the sideropenic subjects who were given only micronutrients. The nonsideropenic group displayed improved MQ when given only micronutrients. In contrast, all but the Fe group improved with the BC Test. The findings suggest that Fe and Zn repletion of sideropenic women improved certain cognitive functions of the women.

    2013-10-01

    An analysis is made of the controversial application of the theory of disproportionate damage in the anaesthetic act, due to the high inherent risk, and regardless of the seriousness and importance of the surgery being performed. The existence of a disproportionate damage, that is, damage not foreseen nor accountable within the framework of the professional performance of the anaesthetist, does not by itself determine the existence of liability on the part of the anaesthetist, but the demand from the professionals themselves for a coherent explanation of the serious disagreement between the initial risk implied by their actions and the final consequence produced.

    OBJECTIVES. One way of promoting a reduction in dietary fat intake is by changing the diet of family members. This study investigated the long-term effects of a low-fat dietary intervention on husbands of women who participated in the Women's Health Trial (WHT). METHODS. An average of 12 months after the end of the WHT, a randomly selected sample of participants' husbands was sent dietary and health questionnaires as part of a follow-up study of the maintenance of the low-fat diet among WHT participants. RESULTS. We found an absolute difference in fat intake between groups of 4 percentage points (32.9% energy from fat among intervention husbands [n = 188] vs 36.9% among control husbands [n = 180]). The wife's attitude and fat intake were among the most important predictors of her husband's fat intake, indicating that the effect of the WHT intervention on the husbands of participants was more likely due to their acceptance of lower-fat foods being served at home than to overt actions by the men. CONCLUSIONS. Our results suggest that a dietary intervention aimed at women can have an effect on their husbands and may be a cost-effective approach to healthy dietary change for both women and men.

    2012-04-01

    Multiple complex factors contribute to the slow pace of women's advancement into leadership positions in academic medicine. In this article, the authors propose that stereotype threat--under which individuals who are members of a group characterized by negative stereotypes in a particular domain perform below their actual abilities in that domain when group membership is emphasized--may play an important role in the underrepresentation of women in leadership positions in academic medicine. Research to objectively assess the impact of stereotype threat for women in academic medicine is feasible and necessary to confirm this hypothesis. Still, a number of conditions present in the academic medicine community today have been shown to trigger stereotype threat in other settings, and stereotype threat fits with existing research on gender in academic medicine. In the meantime, academic health centers should implement relatively simple measures supported by experimental evidence from other settings to reduce the risk of stereotype threat, including (1) introducing the concept of stereotype threat to the academic medicine community, (2) engaging all stakeholders, male and female, to promote identity safety by enacting and making faculty aware of policies to monitor potential instances of discrimination, and training faculty to provide performance feedback that is free of gender bias, (3) counteracting the effects of sex segregation at academic health centers by increasing exposure to successful female leaders, (4) reducing gender stereotype priming by avoiding stereotypically male criteria for promotion, grants, and awards, and (5) building leadership efficacy among female physicians and scientists.

  19. Linking Medicaid Expansion and Cuts to Disproportionate-Share Hospitals: Will Safety Nets Survive?

    PubMed

    Gurewitsch Allen, Edith D; Bittle, Mark J

    2015-08-01

    The predominant mechanism by which the health care reforms of the Patient Protection and Affordable Care Act of 2010 are to be financed is through the government's simultaneous defunding of major portions of Medicare and Medicaid, including the reduction of up to 75% of federal payments to disproportionate-share hospitals. The justification for curtailment of other public programs is that after Medicaid expansion under the Affordable Care Act, the decrease in the proportion of uninsured among the U.S. population will render disproportionate-share hospital payments extraneous and unnecessary. Such justification was reiterated in the recent American College of Obstetricians and Gynecologists Committee Opinion No. 627, entitled Health Care for Unauthorized Immigrants. Herein, the soundness of the Committee Opinion's proposed policy is evaluated by reviewing available literature on the potential effect of Medicaid disproportionate-share hospital cuts with and without concomitant Medicaid expansion. Limitations of Medicaid expansion efforts before and under the Affordable Care Act, the disproportionate-share hospital payment program, and other legislation providing safety net hospitals with (some) relief of financial burdens related to uncompensated care are explicated. Findings raise concern that acceptance of cuts of up to 75% of federal disproportionate-share hospital funds on the premise that nationwide state expansion of Medicaid will offset the difference may be overly optimistic. Indeed, foregoing disproportionate-share hospital payments undercuts the otherwise laudable intent of Committee Opinion No. 627, namely to advocate for universal health care for all women, including undocumented immigrants.

    This study examined the impact of ultraviolet (UV) photography, cognition versus affect, and age on women's sun-related cognitions and a proxy measure of sun protection behavior. Participants (N = 114) were recruited via public advertisements and came to the lab to view a photo showing their UV damage. In addition, some participants received instructions to focus on either their thoughts (cognition) or feelings (affect) about their photograph before completing the survey. Women in the affect condition reported the lowest perceived vulnerability to skin cancer and highest absent/exempt beliefs (beliefs that one is unlikely to develop skin cancer if she hasn't already). Condition by age interactions showed that, among those in the cognition and control (no instructions) conditions, older women reported higher perceived vulnerability and lower absent/exempt beliefs, and took more sunscreen than younger women. However, older women reported higher absent/exempt beliefs and higher sun-risk willingness than younger women in the affect condition. PMID:23624642

    2007-09-01

    It is assumed that psychological stress may inhibit sexual arousal in women. Research on the effect of (acute and chronic) psychological stressors on genital and subjective sexual arousal, however, is scarce. To investigate whether psychological stressors indeed inhibit sexual responding, sexually functional women were randomly assigned to an experimental condition (n=30) in which acute psychological stress was induced by a frustrating computer task or a control condition (n=29). After the acute psychological stress or control induction women were exposed to an erotic stimulus. Genital sexual arousal was assessed using vaginal photoplethysmography. Self-report ratings of subjective sexual arousal were collected after the erotic stimulus. Furthermore, women were post hoc divided into a 'low' and a 'high' chronic stress group, based on their pre-assessment scores on a chronic daily stress questionnaire. As predicted, it was found that women in the acute stress condition responded with lower levels of genital and subjective sexual arousal to an erotic stimulus than women in the control condition. In addition, women with high levels of chronic stress responded with lower levels of genital sexual arousal to an erotic stimulus than women with low levels of chronic stress. Chronic stress did not affect the level of subjective sexual arousal. PMID:17481578

    Although several studies suggest that negative affect and interpersonal problems serve as important contributors for eating-related problems, much of this research has been conducted among women and less is known about their roles in precipitating and maintaining eating problems among men. Previous studies with undergraduate men suggest that difficulties in emotion regulation are associated with disordered eating even after controlling for differences in body mass index (BMI) and negative affect. The present study sought to replicate these findings and extend them to assess any unique variance explained by problems in interpersonal functioning among both men and women. Participants were men (n=213) and women (n=521) undergraduates at a large Midwestern university who completed a demographic information form, the Eating Disorder Examination-Questionnaire (EDE-Q), the Difficulties in Emotion Regulation Scale (DERS), the Positive and Negative Affect Schedule, and the Inventory of Interpersonal Problems-Short Circumplex Form (IIP-SC). A series of hierarchical regression analyses indicated that DERS and IIP-SC significantly predicted EDE-Q global scores after controlling for variability in BMI and negative affect and that the results were similar for men and women. Our findings offer preliminary support for models that highlight emotional vulnerability and interpersonal problems for disordered eating for young adult men. Future research extending these findings among treatment-seeking samples and employing multi-method assessment would serve to further clarify the tenability of these theoretical models for both men and women.

    2013-01-01

    Objectives. We investigated the impact of HIV status on fertility desires in Uganda. Methods. We surveyed 1594 women aged 18 to 49 years visiting outpatient services at Mbarara Regional Hospital, from May through August 2010. Of these, 59.7% were HIV-positive; 96.4% of HIV-positive women were using antiretroviral therapy (ART). We used logistic regression models to examine relationships between HIV status and fertility desires, marital status, household structure, educational attainment, and household income. Results. Among married women, HIV-positive status was significantly associated with a lower likelihood of desiring more children (27.7% vs 56.4% of HIV-negative women; χ2 = 39.97; P < .001). The difference remained highly significant net of age, parity, son parity, foster children, education, or household income. HIV-positive women were more likely to be poor, unmarried, single heads of household, in second marriages (if married), living with an HIV-positive spouse, and supporting foster children. Conclusions. We found a strong association between positive HIV status and lower fertility aspirations among married women in Uganda, irrespective of ART status. Although the increasing availability of ART is a tremendous public health achievement, women affected by HIV have numerous continuing social needs. PMID:23237166

    The author utilized semistructured interviews with 56 women to explore how a wide range of activities affected the development of the participants' same-sex attractions and relationships. The researcher was able to identify and describe some aspects of the process by which eight characteristics of activities that are more or less present in various social contexts have the potential to impact whether these contexts are more or less conducive or hindering to the development of women's same-sex attractions and relationships. Activities were more apt to nurture the development of the participants' same-sex attractions and relationships when the activity (a) included lesbians, (b) was composed primarily of women, (c) affirmed women, (d) facilitated bonding, (e) featured a climate of acceptance of lesbians/gays/bisexuals, (f) did not feature a climate that emphasized heteronormativity, (g) was perceived as gender neutral, and (h) generated or drew participants who were similar to each other.

    This study aimed to identify and to assess the important factors affecting perinatal mortality (PNM) in Cairo. 200 women were selected randomly from the gynecology and obstetric department of Bab El-Shaaria University Hospital. 100 women were the case group of perinatal deaths, while the other 100 women formed the control group. Both groups had similar life styles. The attendance rate for prenatal care was more frequent among the control group. High parity, short birth intervals, twins, preterm births, a birth order of 4 or higher, anemia, diabetes mellitus, and maternal age of 30 years and older were more prevalent among the case group and considered risk factors for perinatal mortality. Adequate health care and family planning services must be available to all women of reproductive age. Good prenatal care is needed for the prevention and control of coexisting diseases, and good obstetric care is needed to prevent the premature rupture of membranes. PMID:12295112

    Background: Polycystic ovary syndrome (PCOS) is the most common chronic endocrine disorder. It has significant and diverse clinical consequences including reproductive, metabolic, and psychological morbidities as well as predisposition to malignancies. It is unclear how women with PCOS experience symptoms of this syndrome. Objectives: The aim of this study was to clarify the dimensions and components of quality of life in iranian women with PCOS. Patients and Methods: This study was a qualitative study to explore and document perceptions of women with PCOS about their disorder and quality of life. Semi-structured interviews with open ended questions were conducted with 23 women with PCOS. The interviews were continued to reach data saturation. The study was conducted in the Reproductive Endocrinology Research Center of Shahid Beheshti University of Medical Sciences. All the interviews were recorded and transcribed. Constant comparative analysis of the data was conducted manually according to the Strauss and Corbin analysis method. Results: The study revealed that the most important factors affecting quality of life in women with PCOS were the role functioning items as well as physical, mental, emotional, cognitive, and social dimensions. Conclusions: Comprehensive cares concerning various mental, emotional, cognitive, and social dimensions of quality of life should be planned for women with PCOS. PMID:24829583

    Family history of first and second-degree relatives is known to increase the risk for breast cancer. Less data are available on the risks between defined multiple affected close and distant relatives for which the reliability of data may be an issue. Data on affected males are sparse. These questions and the probable genetic models were addressed in this study by means of a nationwide Swedish Family-Cancer Database. We estimated the effect of family history of breast cancer by Poisson regression for women of at least 30 years of age after adjusting for age, period, region, socioeconomic status, number of children, and age at first birth. The results of the study showed that relative risk (RR) for breast cancer was associated with a first degree as well as second-degree family history. Having at least two female affected first-degree relatives increased the RR at least to 2.8, favoring an additive interaction. The risk was increased around ten times in women with both parents affected. When either a father or a mother was affected, the RRs were nearly identical (RR = 1.73 and 1.74, respectively). The RR for a woman increased more when a brother was affected (RR = 2.48) compared to when a sister was affected (RR = 1.87). Having an affected grandmother showed lower familial excess risks than having an affected half sister (RR = 1.27, and 1.26; and RR = 1.39, and 1.50; respectively, for maternal and paternal relatives). We concluded that when both parents were diagnosed with breast cancer, the risk for the daughter was increased tenfold. Having an affected brother showed a somewhat higher risk than having an affected sister. The data suggest that male breast cancer has a higher genetic basis than female breast cancer, which invites further search of the underlying mechanisms. PMID:22179927

    This study aimed to assess the range and intensity of psychosocial concerns experienced by women with cervical cancer and their male partners. A cross-sectional survey assessed 26 couples where the woman had invasive cervical cancer stage I-IV, up to 2 years posttreatment, using a concerns questionnaire and widely used psychosocial questionnaires. Respondents indicated their concerns about the impact of the disease and treatment as well as general psychosocial impact. Women with cervical cancer and their male partners expressed equal intensities of concern regarding the illness and its treatment, rating sexuality, prognosis, and communication with the treatment team most highly in terms of current concerns. Couples where the patient had a more advanced stage of cancer expressed higher concerns than those with earlier stage disease. Although women with cervical cancer reported more fatigue and illness intrusiveness than their male partners, both experienced disruptions in relationships, intimacy, and instrumental life domains. With increased time posttreatment, concerns differed subtly between affected women and their male partners. Effective psychosocial support for cervical cancer must be provided for both the affected woman and her male partner. Support and information should address the most salient concerns of patients and partners as these evolve over significant clinical milestones. PMID:16174246

    This study aims to quantitatively characterize plantar pressure distribution in women affected by Ehlers-Danlos syndrome of the hypermobile type (EDS-HT) to verify the existence of peculiar patterns possibly related to postural anomalies or physical and functional lower limb impairments typical of this disease. A sample of 26 women affected by EDS-HT (mean age 36.8, SD 12.0) was tested using a pressure platform in two conditions, namely static standing and walking. Raw data were processed to assess contact area and mean and peak pressure distribution in rearfoot, midfoot and forefoot. Collected data were then compared with those obtained from an equally numbered control group of unaffected women matched for age and anthropometric features. The results show that, in both tested conditions, women with EDS-HT exhibited significantly smaller forefoot contact areas and higher peak and mean pressure than the control group. No differences in the analyzed parameters were found between right and left limb. The findings of the present study suggest that individuals with EDS-HT are characterized by specific plantar pressure patterns that are likely to be caused by the morphologic and functional foot modification associated with the syndrome. The use of electronic pedobarography may provide physicians and rehabilitation therapists with information useful in monitoring the disease's progression and the effectiveness of orthotic treatments.

    [Purpose] This study aimed to examine the quality of life (QOL) of community-dwelling elderly women with musculoskeletal disorders and factors that affect it. [Subjects] The subjects were 27 community-dwelling elderly women with musculoskeletal disorders (mean age: 76.3 ± 7.4 years). Their physical and psychological conditions, QOL, and other characteristics were researched. [Methods] The Japanese version of Life-Space Assessment was used to assess the subjects' daily life activities; the Japanese version of Fall Efficacy Scale (FES), to assess their fear of falling; the Geriatric Depression Scale (GDS 15), to assess their depression status; and the Life Satisfaction Index K (LSIK), to assess their QOL. [Results] The results indicated that the number of family members living together, degree of pain, fear of falling, and depression affect the LSIK scores of the community-dwelling elderly women with musculoskeletal disorders. [Conclusion] The study results suggest that the LSIK scores of community-dwelling elderly women with musculoskeletal disorders can be improved by easing their pain, improving their physical abilities to prevent falls, and improving their mobility. The results also suggest that continuing rehabilitation treatment is required. PMID:26696713

    Mounting evidence indicates that the development of the fetus is heavily influenced by the intra-uterine milieu during pregnancy, and that such influence may have life-long consequences for the individual. The intra-uterine milieu is not only influenced by nutritional factors, but also by maternal endocrine and autonomic activity. Such activity is prone to be affected by an individual's personality, but only little is known about influences of maternal personality on the development of the fetus. We tested pregnant women for their propensity for impulsive, uncontrollable outbursts of temper (referred to here as moderate Intermittent Explosive Disorder, mIED). After the women gave birth, we measured electrocardiograms (ECGs) from their newborn infants to compare ECGs between newborns of women with and without mIED. The data show that infants of women with mIED have larger QRS complexes in the electrocardiogram, and lower heart rate variability, compared to infants of women without mIED. These results reveal effects of maternal mIED on the fetal heart development. These effects may predispose the individual to increased risk for later cardio-vascular disease. The findings open perspectives for better risk prevention models for the unborn child. PMID:19804798

  2. Women's sexual responses to heterosexual and lesbian erotica: the role of stimulus intensity, affective reaction, and sexual history.

    Past research has demonstrated that women do not show a "category-specific" genital response to erotic stimuli. That is, on average, heterosexual and lesbian women are indistinguishable in terms of their physiological genital responses to heterosexual versus lesbian erotica. In two studies with heterosexual women (n = 28 for Study 1; n = 30 for Study 2) and lesbians (n = 24 for Study 1; n = 25 for Study 2), results confirmed that, on average, women did not show category-specific genital responses or category-specific subjective sexual arousal. However, there was evidence of notable within-group variability; many women did respond to the stimuli in a category-specific manner. Heterosexual women were more likely than lesbian women to demonstrate category-specificity. Findings also revealed that category-specificity was associated with multiple factors, including affective responses to the erotic stimuli and sexual history. Results of this study highlight the complexity of women's sexual identities and sexual responses. PMID:19856092

  8. Disproportionation of photoexcited C{sub 60}

    SciTech Connect

    Yang, C.C.; Hwang, K.C.

    1996-05-15

    Irradiation of C{sub 60}-toluene solution at room temperature affords two ESR bands with g and {Delta}H{sub pp} values of (2.0013, 0.5 G) and (2.0024, 0.75 G), respectively. In the presence of 6% methanol or 12% benzonitrile, the latter band disappears completely. Below 200 K, only the former bank was observed. They were assigned to be {sup 3}C{sub 60} and C{sub 60}{sup .+}, respectively. In the presence of tetraphenylphosphonium tetraphenylborate, the g value of the C{sub 60}{sup .+} cation radical shifts to 2.0006, and an additional broad band of g = 1.9992 and {Delta}H{sub pp}=30 G was observed. Upon cooling, the line width of this new band drops from 30 G at 300 K to 4 G at 77 K. This new band was assigned to be the C{sub 60}{sup .-} anion radical according to its characteristic behavior. At room temperature, photolysis causes the C{sub 60}-toluene solution`s color to turn from purple to brown, and then brown precipitates formed. Desorption chemical ionization (DCI) mass analysis of the brown precipitates indicates the formation of C{sub 60}.H{sub n}(tolyl){sub n} (n = 1-4) adducts. The formation of C{sub 60}{sup .+} and C{sub 60}{sup .-} was rationalized in terms of disproportionation of two {sup 3}C{sub 60}. The brown precipitates were due to the chemical reaction between the C{sub 60}{sup .+} cation radical and the solvent molecules, which rationalizes the `photodegradation` of fullerene as reported in literature. 38 refs., 5 figs.

  10. How does marriage protect women with histories of affective disorder from post-partum relapse?

    PubMed

    Marks, M; Wieck, A; Checkley, S; Kumar, C

    1996-12-01

    Interviews were carried out at 36 weeks antenatal with 63 married couples, in 36 of which the woman had a history of affective disorder and in 27 the woman had no previous psychiatric history. The men's attitudes to their wives were assessed using expressed emotion methodology. Also assessed were psychiatric history, neuroticism, satisfaction with the marital relationship and attitudes to sex, pregnancy and parenthood in both the woman and her partner. Women with psychiatric histories who did not relapse in the six months following delivery had partners who were more positive about them than partners of high-risk women who remained well and control women. This effect is explored further by examining which characteristics of the man and which of the woman contributed to his critical and positive comment score. Criticism of his wife was associated with each partner reporting less marital satisfaction and also with the man's psychiatric history. No characteristic of the woman contributed to her partner's criticism. In contrast, the men's positive comments about their wives were associated with the woman's satisfaction with key aspects of her femaleness. Positive husbands had wives were pleased to be pregnant, happy with their pregnant bodies and enjoying the sexual aspect of the marital relationship. In women with psychiatric histories the time which had elapsed since her last psychiatric admission also influenced his positive comments. PMID:8989981

    The paper contains an analysis of the factors affecting the quality of life (QoL) and the illness acceptance of diabetic pregnant women. The study was performed between January and April, 2013. It included 114 pregnant women with diabetes, hospitalized in the High Risk Pregnancy Wards of several hospitals in Lublin, Poland. The study used a diagnostic survey with questionnaires. The research instruments used were: The WHOQOL-Bref questionnaire and the Acceptance of Illness Scale (AIS). The women’s general quality of life was slightly higher than their perceived general health. A higher quality of life was reported by women with a very good financial standing, very good perceived health, moderate self-reported knowledge of diabetes, and also by those only treated with diet and stating that the illness did not interfere with their lives (p < 0.05). Women with a very good financial standing (p < 0.009), high self-reported health (p < 0.002), and those treated with by means of a diet (p < 0.04) had a higher acceptance of illness. A higher acceptance of illness contributes to a higher general quality of life and a better perception of one’s health. PMID:26703697

    [Purpose] The aim of this study was to observe the effect of self-selected intensity or imposed intensity during aerobic training on perceptual and affective responses in obese women. [Subjects] The study included 26 obese women aged 30–60 years. [Methods] The subjects were randomly divided into two groups, with 13 subjects in each group: self-selected intensity and imposed intensity (10% above ventilatory threshold) groups. All subjects completed an intervention program that lasted 12 weeks, with three exercise sessions a week. The rating of perceived exertion and affective responses (Feeling Scale and Felt Arousal Scale) were monitored in the first, sixth, and twelfth weeks. [Results] Significant differences were observed between groups in heart rate and rating of perceived exertion. The affective responses during exercise were more negative in the imposed intensity group. [Conclusion] Use of a self-selected exercise intensity can promote smaller negative affective responses during exercise and provide a sufficient stimulus for improvement in cardiorespiratory fitness.

    The present study aims to examine the influence of negative affect on decision making in women with anorexia nervosa (AN) compared to healthy control women and, secondly, to assess differences between the restrictive (ANR) and binge-purge (ANBP) subtypes. One hundred four women (32 with ANR, 32 with ANBP, and 40 healthy controls) participated. All women were asked to watch either a negative or a control film fragment, both followed by the Bechara Gambling Task (BGT). Before and after the fragments negative affect was measured. Additionally, relevant characteristics (e.g., overall depressive symptoms) were assessed. Differences in negative affect did not influence decision making performance. Independent of affective state, decision making was found to be impaired in women with ANBP (no learning effect on the BGT), but not in women with ANR. These findings highlight the importance of considering different AN subtypes when examining decision making processes. However, the role of negative affect on decision making remains uncertain. Since other affect related factors such as affect dysregulation may also play a role, future studies on decision making in AN should take the role of affect into account. PMID:27137960

  15. Does Schooling Affect Women's Desired Fertility? Evidence From Malawi, Uganda, and Ethiopia.

    PubMed

    Behrman, Julia Andrea

    2015-06-01

    Demographic scholarship suggests that schooling plays an important role in transforming fertility preferences in the early stages of fertility decline. However, there is limited evidence on the relationship between schooling and fertility preferences that addresses the endogeneity of schooling. I use the implementation of Universal Primary Education (UPE) policies in Malawi, Uganda, and Ethiopia in the mid-1990s to conduct a fuzzy regression discontinuity analysis of the effect of schooling on women's desired fertility. Findings indicate that increased schooling reduced women's ideal family size and very high desired fertility across all three countries. Additional analyses of potential pathways through which schooling could have affected desired fertility suggest some pathways--such as increasing partner's education--were common across contexts, whereas other pathways were country-specific. This analysis contributes to demographic understandings of the factors influencing individual-level fertility behaviors and thus aggregate-level fertility decline in sub-Saharan Africa.

    The present work explores the unconscious and/or conscious nature of learning attractive faces of same and opposite sex, that is, of stimuli that experimental and neuroimaging research has shown to be rewarding and thus highly motivating. To this end, we examined performance of men and women while classifying strings of average and attractive faces for grammaticality in the experimental task of artificial grammar learning (AGL), which reflects both conscious and unconscious processes. Subjective measures were used to assess participants’ conscious and unconscious knowledge. It was found that female attractiveness impaired performance in male participants. In particular, male participants demonstrated the lowest accuracy while classifying beautiful faces of women. Conversely, female attractiveness facilitated performance in female participants. The pattern was similar for conscious and unconscious knowledge. Presumably, objects with high incentive salience, as are beautiful faces, captured resources, which were used in task relevant versus task irrelevant ways by women versus men. The present findings shed light on the relation of conscious and unconscious processing with affective and reward-related stimuli, as well as on gender differences underlying this relation.

    Objective To determine if elevated body mass index in young women with normal ovarian reserve was associated with poorer ovarian response, difficulty at embryo transfer, and lower clinical pregnancy rates. Materials and methods Retrospective study of 417 first, fresh in vitro fertilization cycles performed between October 2004 and December 2006. All women were under the age of 35 and had normal cycle day 3 follicle stimulating hormone and estradiol levels. Subjects were divided into groups by BMI: <18.5, 18.5–24.9, 25–29.9, ≥30. Results Cancellation rates, peak estradiol levels, and mean number of oocytes retrieved were similar in all groups. There was a trend toward increasing difficulty in visualizing the air bubble at time of embryo transfer and lower implantation rates at higher body mass indices. Clinical and ongoing pregnancy rates were similar among groups. Conclusion Obesity in young women does not adversely affect clinical pregnancy rates in patients treated with in vitro fertilization.

    The degradation of transitory starch in the chloroplast to provide fuel for the plant during the night requires a suite of enzymes that generate a series of short chain linear glucans. However, glucans of less than four glucose units are no longer substrates for these enzymes, whereas export from the plastid is only possible in the form of either maltose or glucose. In order to make use of maltotriose, which would otherwise accumulate, disproportionating enzyme 1 (DPE1; a 4-α-glucanotransferase) converts two molecules of maltotriose to a molecule of maltopentaose, which can now be acted on by the degradative enzymes, and one molecule of glucose that can be exported. We have determined the structure of the Arabidopsis plastidial DPE1 (AtDPE1), and, through ligand soaking experiments, we have trapped the enzyme in a variety of conformational states. AtDPE1 forms a homodimer with a deep, long, and open-ended active site canyon contained within each subunit. The canyon is divided into donor and acceptor sites with the catalytic residues at their junction; a number of loops around the active site adopt different conformations dependent on the occupancy of these sites. The “gate” is the most dynamic loop and appears to play a role in substrate capture, in particular in the binding of the acceptor molecule. Subtle changes in the configuration of the active site residues may prevent undesirable reactions or abortive hydrolysis of the covalently bound enzyme-substrate intermediate. Together, these observations allow us to delineate the complete AtDPE1 disproportionation cycle in structural terms. PMID:26504082

    Obstetric fistula is still a major problem in low income countries. While its main cause is untreated obstructed labour, misconceptions about it still persist. This study aimed at exploring and describing perceived health system causes of obstetric fistula from women affected by it in rural Tanzania. This exploratory qualitative study included twenty-eight women affected by obstetric fistula. Semi structured interviews and focus group discussions were held and thematic analysis used to analyse perceived health system causes of obstetric fistula from women's account. Perceived health system causes of obstetric fistula fundamentally reflected the poor quality of obstetric care women received at health care facilities relating to staff unaccountability, late referral, and torture by nurses. The women's perception emphasizes the importance of improving the quality of obstetric care provided by health care providers in health care facilities. PMID:26103702

    This study investigated the time-course of stress and recovery states and their relations to social support and personality traits in healthy women during a long-term head-down tilt bed rest. Personality, social support and affective states were assessed in 16 women exposed to simulated microgravity for a 60-day duration involving three stages: a 20-day baseline control period (BDC), a 60-day head-down tilt bed rest (HDT) and a 20-day post-HDT ambulatory recovery period (R+). Participants were divided into two groups: an exercise (Exe, n = 8) and a control group (Ctl, n = 8). All the participants experienced significantly more stress during the HDT period. But exercise did not improve the impaired effects of simulated microgravity. The Exe group perceived more stress and less recovery than the Ctl group during the HDT period. Among the five major personality factors, only Neuroticism was related to both social and affective variables. Neuroticism was positively associated with stress and negatively associated with recovery and social support (S-SSQ). Practical implications in psychological countermeasures for better dealing with the key human factor in spaceflights are discussed.

    Misreporting of dietary intake affects the validity of data collected and conclusions drawn in studies exploring diet and health outcomes. One consequence of misreporting is biological implausibility. Little is known regarding how accounting for biological implausibility of reported intake affects nutrient intake estimates in Hispanics, a rapidly growing demographic in the United States. Our study explores the effect of accounting for plausibility on nutrient intake estimates in a sample of Mexican-American women in northern California in 2008. Nutrient intakes are compared with Dietary Reference Intake recommendations, and intakes of Mexican-American women in a national survey are presented as a reference. Eighty-two women provided three 24-hour recalls. Reported energy intakes were classified as biologically plausible or implausible using the reported energy intakes to total energy expenditure cutoff of <0.76 or >1.24, with low-active physical activity levels used to estimate total energy expenditure. Differences in the means of nutrient intakes between implausible (n=36) and plausible (n=46) reporters of energy intake were examined by bivariate linear regression. Estimated energy, protein, cholesterol, dietary fiber, and vitamin E intakes were significantly higher in plausible reporters than implausible. There was a significant difference between the proportions of plausible vs implausible reporters meeting recommendations for several nutrients, with a larger proportion of plausible reporters meeting recommendations. Further research related to misreporting in Hispanic populations is warranted to explore the causes and effects of misreporting in studies measuring dietary intake, as well as actions to be taken to prevent or account for this issue.

    2014-01-01

    Previous descriptive, correlational, and quasi-experimental research has established that weight concerns and negative body image are associated with tobacco smoking, cessation, and relapse among young women. A recent experimental study found that activation of negative body image cognitions produced urges to smoke (Lopez, Drobes, Thompson, & Brandon, 2008). The current study intended to replicate and extend these experimental findings by examining the role of negative affect as a mediator of the relationship between body dissatisfaction and smoking urges. Female college smokers (N = 133) were randomly assigned to a body image challenge (trying on a bathing suit) or a control condition (evaluating a purse). State levels of urge to smoke, mood, and body dissatisfaction were assessed both pre- and post-manipulation. Trying on a bathing suit increased body dissatisfaction and reported urges to smoke, particularly those urges related to reducing negative affect. Additionally, state negative affect mediated the relationship between the body image manipulation and smoking urge. This study provides additional support, through an experimental design, that situational challenges to body image influence smoking motivation, and that this effect occurs, at least in part, via increases in negative affect. Theoretical and applied implications are discussed. PMID:19586144

    STUDY QUESTION Is there a difference in fertility between heterosexual women and lesbians undergoing sperm donation? SUMMARY ANSWER Women undergoing treatment with donated sperm are equally fertile regardless of sexual orientation. WHAT IS KNOWN ALREADY Lesbians have an increased prevalence of smoking, obesity, sexually transmitted diseases and, possibly, polycystic ovary syndrome, all factors known to affect fertility. Previous studies on sperm donation inseminations (D-IUI) show conflicting results regarding pregnancy outcome. STUDY DESIGN, SIZE, DURATION This is a national study of 171 lesbians and 124 heterosexual women undergoing sperm donation both as D-IUI (lesbian n = 438, heterosexual n = 298) and as embryo transfers (ET) after IVF with donated sperm (lesbians n = 225, heterosexuals n = 230) during 20052010. PARTICIPANTS/MATERIALS, SETTING, METHODS All clinics in Sweden offering sperm donation recruited patients. Differences in patients' medical history, treatment results and number of treatments to live birth were analyzed using independent samples t-test, Pearson's ?2 test or Fisher's exact probability test. MAIN RESULTS AND THE ROLE OF CHANCE 71.8% of heterosexuals and 69.0% of lesbians had a child after treatment. The mean number of treatments was 4.2 for heterosexual women and 3.9 for lesbians. The total live birth rate, regardless of treatment type, was 19.7% for heterosexuals and 19.5% for lesbians. For D-IUI, the live birth rate was 12.8% for heterosexuals and 16.0% for lesbians and the live birth rate for all IVF embryo transfers (fresh and thawed cycles) was 28.7% for heterosexuals and 26.2% for lesbians. There were no differences in live birth rate between the groups for each of the different types of insemination stimulations (natural cycle; clomiphene citrate; FSH; clomiphene citrate and FSH combined). Nor was there a difference in live birth rate between the groups for either fresh or thawed embryo transfer. There was no difference between the proportions of women in either group or the number of treatments needed to achieve a live birth. Heterosexuals had a higher prevalence of smokers (9.2%), uterine polyps (7.2%) or previous children (11.3%) than lesbians (smokers 2.8%, P = 0.03; polyps 1.8%, P = 0.03; child 2.5%, P = 0.003). LIMITATIONS, REASONS FOR CAUTION This study is limited to women living in stable relationships undergoing treatment with donated sperm in a clinical setting and may not apply to single women or those undergoing home inseminations. WIDER IMPLICATIONS OF THE FINDINGS These results may influence healthcare policy decisions as well as increase the quality of clinical care and medical knowledge of healthcare professionals. The data also have important implications for individuals regarding screening, infertility diagnostic procedures and treatment types offered to heterosexuals and lesbians seeking pregnancy through sperm donation.

    Background The bi-relationships between psychological stress, negative affect and disordered eating has been well studied in western culture, while tri-relationship among them, i.e. how some of those factors influence these bi-relationships, has rarely been studied. However, there has been little related study in the different Chinese culture. This study was conducted to investigate the bi-relationships and tri-relationship between psychological stress, negative affect, and disordered eating attitudes and behaviors in young Chinese women. Methodology A total of 245 young Chinese policewomen employed to carry out health and safety checks at the 2010 Shanghai World Expo were recruited in this study. The Chinese version of the Perceived Stress Scale (PSS-10), Beck Depression Inventory Revised (BDI-II), Beck Anxiety Inventory (BAI), and Eating Attitude Test (EAT-26) were administered to all participants. Principal Findings The total scores of PSS-10, BDI-II and BAI were all highly correlated with that of EAT-26. The PSS-10 score significantly correlated with both BDI-II and BAI scores. There was no statistically significant direct effect from perceived stress to disordered eating (–0.012, 95%CI: –.038∼0.006, p = 0.357), however, the indirect effects from PSS-10 via affect factors were statistically significant, e.g. the estimated mediation effects from PSS to EAT-26 via depression and anxiety were 0.036 (95%CI: 0.022∼0.044, p<0.001) and 0.015 (95%CI: 0.005∼0.023, p<0.01), respectively. Conclusions Perceived stress and negative affects of depression and anxiety were demonstrated to be strongly associated with disordered eating. Negative affect mediated the relationship between perceived stress and disordered eating. The findings suggest that effective interventions and preventative programmes for disordered eating should pay more attention to depression and anxiety among the young Chinese female population.

    This article is part of a Special Issue "Estradiol and Cognition". Natural fluctuations of sex hormones during the menstrual cycle have been shown to modulate language lateralisation. Using the dichotic listening (DL) paradigm, a well-established measurement of language lateralisation, several studies revealed that the left hemispheric language dominance was stronger when levels of estradiol were high. A recent study (Hjelmervik et al., 2012) showed, however, that high levels of follicular estradiol increased lateralisation only in a condition that required participants to cognitively control (top-down) the stimulus-driven (bottom-up) response. This finding suggested that sex hormones modulate lateralisation only if cognitive control demands are high. The present study investigated language lateralisation in 73 normally cycling women under three attention conditions that differed in cognitive control demands. Saliva estradiol and progesterone levels were determined by luminescence immunoassays. Women were allocated to a high or low estradiol group. The results showed a reduced language lateralisation when estradiol and progesterone levels were high. The effect was independent of the attention condition indicating that estradiol marginally affected cognitive control. The findings might suggest that high levels of estradiol especially reduce the stimulus-driven (bottom-up) aspect of lateralisation rather than top-down cognitive control. PMID:26145565

  11. Redox Disproportionation of Glucose as a Major Biosynthetic Energy Source

    Previous studies have concluded that very little if any energy is required for the microbial biosynthesis of amino acids and lipids from glucose -- processes that yield almost as much ATP (adenosine triphosphate) as they consume. However, these studies did not establish the strength nor the nature of the energy source driving these biological transformations. To identify and estimate the strength of the energy source behind these processes, we calculated the free energy change due to the redox disproportionation of substrate carbon of (a) 26 redox-balanced fermentation reactions, and (b) the biosynthesis of amino acids, lipids, and nucleotides of E. coli from glucose. A plot of the negative free energy of these reactions per mmole of carbon as a function of the number of disproportionative electron transfers per mmol of carbon showed that the energy yields of these fermentations and biosyntheses were directly proportional to the degree of redox disproportionation of carbon. Since this linear relationship showed that redox disproportionation was the dominant energy source of these reactions, we were able to establish that amino acid and lipid biosynthesis obtained most of their energy from redox disproportionation (greater than 94%). In contrast nucleotide biosynthesis was not driven by redox disproportionation of carbon, and consequently depended completely on ATP for energy. This crucial and previously unrecognized role of sugars as an energy source of biosynthesis suggests that sugars were involved at the earliest stage in the origin of anabolic metabolism.

    Hispanic women (HW) are disproportionately affected by HIV, however, little is known regarding their perceived susceptibility for acquiring HIV (SAHIV). We studied predictive factors for perceiving SAHIV among HW. Participants (88.5%) reported not feeling SAHIV. Women who felt SAHIV, had a significant probability of reporting a higher chance for acquiring HIV from their partner’s actions (OR 9.75), and a higher probability of not being tested for HIV (OR 2.05). Educational strategies to increase perception of SAHIV and HIV testing knowledge would be beneficial giving emphasis to women who do not perceive to be at risk from their partner’s actions.

    Solid silicon monoxide is an amorphous material which has been commercialized for many functional applications. However, the amorphous structure of silicon monoxide is a long-standing question because of the uncommon valence state of silicon in the oxide. It has been deduced that amorphous silicon monoxide undergoes an unusual disproportionation by forming silicon- and silicon-dioxide-like regions. Nevertheless, the direct experimental observation is still missing. Here we report the amorphous structure characterized by angstrom-beam electron diffraction, supplemented by synchrotron X-ray scattering and computer simulations. In addition to the theoretically predicted amorphous silicon and silicon-dioxide clusters, suboxide-type tetrahedral coordinates are detected by angstrom-beam electron diffraction at silicon/silicon-dioxide interfaces, which provides compelling experimental evidence on the atomic-scale disproportionation of amorphous silicon monoxide. Eventually we develop a heterostructure model of the disproportionated silicon monoxide which well explains the distinctive structure and properties of the amorphous material. PMID:27172815

    The present study examined the effects of depressive mood symptoms and experimentally adopted sexual schemas on women's sexual arousal and affect. Women's vaginal response, subjective sexual arousal, and affect were measured in response to sexually explicit visual material in a laboratory setting. At baseline on a self-report measure, women with depressive mood symptoms (n = 28) reported significantly lower sexual desire than women with normal mood (n=28), but no significant differences in arousal, orgasm, satisfaction, or pain. Participants were asked to adopt both a positive and negative sexual self-schema prior to viewing erotic stimuli. Women in both mood groups demonstrated significantly greater subjective sexual arousal, vaginal response, and positive affect in the positive schema condition than in the negative schema condition when controlling for anxiety. There were no main effects for mood symptoms. These findings support an information processing conceptualization of sexual arousal and suggest that an acute dose of cognitive sexual schemas can significantly impact subsequent sexual and affective responses. Implications of findings for the assessment and treatment of sexual dysfunction are noted. PMID:16752119

    This paper investigates prenatal care utilization, identifies factors affecting the adequacy of prenatal care, and explores the effect of adequate initial timing of prenatal care on total prenatal care visits among Taiwan new immigrant females. Data was obtained from the 2008 Prenatal Care Utilization among Taiwan New Immigrant Females Survey on women who either had at least one preschool-aged child or had delivered their infants but were still hospitalized (N = 476). The Adequacy of Prenatal Care Utilization Index was applied to rate the prenatal care adequacy. The logistic regression model was used to investigate factors associated with the adequacy of prenatal care utilization, and the linear regression model was estimated to identify the impact of influential factors on the prenatal care usage. Females' nationality, employment, and transportation convenience increased the likelihood of receiving adequate prenatal care. Having adequate initial timing of prenatal care was found to be positively related to the frequency of prenatal care visits. Prenatal care utilization can be affected by factors within the health care system and by characteristics of the population; therefore, a measure of prenatal care utilization cannot distinguish these factors but reflects the result of all of them in varying combinations.

    African American women are disproportionately affected by HIV. Some research has explored if non-disclosing men who have sex with men and women (MSMW) contribute to womens HIV risk. Popular media discourse tends to refer to these men as Down Low or DL. Six focus groups were conducted with 36 African American women in Washington D.C. to examine their knowledge, attitudes, beliefs, and behaviours regarding Down Low/DL men. Three of the focus groups were composed of HIV positive women and three groups were composed of HIV negative women. Data analysis reveals six central subcategories related to womens perspectives on the DL: awareness; suspicion; coping with partner infidelity: male vs. female; sexual health communication; empathy; and religion. No major differences were identified between the HIV positive and HIV negative focus groups. Findings from this study provide insight into African American womens perceptions of African American male sexuality and how these perceptions serve to influence interpersonal relationship factors and womens exposure to HIV risk.

    This longitudinal observational study determined the effect of oral contraceptive (OC) use during adolescence on peak bone mass (PBM). The sample comprised 62 non-Hispanic, White females in The Penn State Young Women's Health Study, who were studied for 8 years between the ages of 12 and 20. There were 28 OC users who used OCs for a minimum of 6 months and were still using them at age 20, and 34 nonusers who had never used the regimen. Total body bone, dedicated hipbone, and body composition measurements were made by dual-energy roentgenogram absorptiometry. There was no difference between OC users and nonusers in the anthropometric, body composition, or total body bone measurements. By age 20, the average duration of OC use by the user group was 22 months. At this age, the groups remained indistinguishable in anthropometric, body composition, total body, and hipbone measurements, and in age of menarche and sports exercise scores. These findings suggest that OC use by healthy, White, teenage females does not affect acquisition of PBM. PMID:11020515

    The present study extended the weight stigma and well-being process model (Tylka et al., 2014) by examining three affect regulation pathways that may help simultaneously explain the predicted inverse association between internalized weight bias and intuitive eating. A weight-diverse sample of 333 college women completed an online survey assessing internalized weight stigma, intuitive eating, body shame, body image flexibility, and self-compassion. Self-reported height and weight were used to calculate body mass index (BMI). Non-parametric bootstrap resampling procedures were computed to ascertain the presence of the indirect effects of internalized weight bias on intuitive eating via the three hypothesized mediators controlling for BMI in a combined model. Results demonstrated that body image flexibility significantly and self-compassion marginally contributed unique variance in accounting for this relationship. Our preliminary cross-sectional findings contribute to a nascent body of scholarship seeking to provide a theoretically-driven understanding of how negative and positive forms of experiencing and relating to the body may co-occur within individuals. Results also point to potential target variables to consider incorporating in later-stage efforts to promote more adaptive ways of eating amidst internalized weight stigma. PMID:26893074

    Four studies tested the impact of exposure to thin images on women's eating behavior. In Study 1, women who were exposed to commercials containing thin models ate less in a taste test than women exposed to neutral commercials. The next two studies revealed that the impact of the thin images could be reduced by challenging the sociocultural norms for appearance. In Study 2, including images of relatively heavier women who have been successful in life (an indirect challenge to the norm) attenuated the impact of the thin images on women's eating behavior. Study 3 demonstrated that convincing women that their peers do not endorse the sociocultural norms also reduced the impact of the thin images. In Study 4, we found that exposure to thin images led to activation of an association between heaviness and rejection and that the more this association was activated, the less participants ate.

    Objective The objective of this study was to determine the effect of body mass index (BMI) during pregnancy in laboratory parameters in the serum of the three groups of pregnant women and in their newborns. Methods This prospective study is comparison between the three groups of pregnant women and their newborns categorized according to their BMI. The study included 128 pregnant women and their newborns. In this study, the concentration of blood count, iron, ferritin, and bilirubin were analyzed in the subjects. Results The pregnant women in the three groups significantly differ in the values of blood count (p < 0.001). Statistically significant difference in iron and ferritin was not found between individual three studied groups of pregnant women (p = 0.947). The newborn of the first group of pregnant women had significantly lower values of ferritin (p < 0.001), leucocytes (p < 0.001), and bilirubin (p < 0.001). Significant positive correlation between BMI of pregnant women and leucocytes, ferritin, and bilirubin of the newborn was found (p < 0.001). Conclusion In this study, the tested pregnant women do not have biochemical signs of anemia, neither do their newborns. It was noted that there was no negative correlation between individual tested biochemical parameters for anemia in pregnant women and their newborns. PMID:27119047

    2012-01-01

    Background and purpose Immediate implant stability is a key factor for success in cementless total hip arthroplasty (THA). Low bone mineral density (BMD) and age-related geometric changes of the proximal femur may jeopardize initial stability and osseointegration. We compared migration of hydroxyapatite-coated femoral stems in women with or without low systemic BMD. Patients and methods 61 female patients with hip osteoarthritis were treated with cementless THA with anatomically designed hydroxyapatite-coated femoral stems and ceramic-ceramic bearing surfaces (ABG-II). Of the 39 eligible patients between the ages of 41 and 78 years, 12 had normal systemic BMD and 27 had osteopenia or osteoporosis. According to the Dorr classification, 21 had type A bone and 18 had type B. Translational and rotational migration of the stems was evaluated with radiostereometric analysis (RSA) up to 2 years after surgery. Results Patients with low systemic BMD showed higher subsidence of the femoral stem during the first 3 months after surgery than did those with normal BMD (difference = 0.6, 95% CI: 0.1–1.1; p = 0.03). Low systemic BMD (odds ratio (OR) = 0.1, CI: 0.006–1.0; p = 0.02), low local hip BMD (OR = 0.3, CI: 0.1–0.7; p = 0.005) and ageing (OR = 1.1, CI: 1.0–1.2; p = 0.02) were risk factors for delayed translational stability. Ageing and low canal flare index were risk factors for delayed rotational stabilization (OR = 3, CI: 1.1–9; p = 0.04 and OR = 1.1, CI: 1.0–1.2; p = 0.02, respectively). Harris hip score and WOMAC score were similar in patients with normal systemic BMD and low systemic BMD. Interpretation Low BMD, changes in intraosseous dimensions of the proximal femur, and ageing adversely affected initial stability and delayed osseointegration of cementless stems in women.

    2013-06-01

    Traumatic victimization and associated problems with posttraumatic stress disorder (PTSD) and affect dysregulation are prevalent among incarcerated women, but there is limited evidence to support psychotherapeutic interventions for these problems in this underserved population. A group psychotherapy designed to enhance affect regulation without trauma memory processing-Trauma Affect Regulation: Guide for Education and Therapy (TARGET)-was compared to a supportive group therapy (SGT) in a randomized clinical trial with 72 incarcerated women with full or partial PTSD. Both interventions achieved statistically significant reductions in PTSD and associated symptom severity and increased self-efficacy. Dropout rates for both interventions were low (<5%). TARGET was more effective than SGT in increasing sense of forgiveness toward others who have caused harm in the past. Group therapy that teaches affect regulation may enhance incarcerated women's ability to achieve affective resolution (forgiveness) while also reducing their victimization-related PTSD and associated symptoms. Experiential-focused supportive group therapy also may reduce victimization-related PTSD and associated symptoms. Both group therapy approaches warrant further study with this vulnerable population.

    Affect dysregulation is pervasive among women with histories of childhood sexual abuse. It is an important aspect of the clinical presentation of posttraumatic stress disorder (PTSD), a disorder that frequently characterizes survivors of childhood abuse. Based on distinctions between approach and avoidance orientations to coping, there is controversy regarding whether initial treatment for trauma survivors should employ an exposure-based approach to increase affect or an affect-management approach to reduce it. In this article, we review theoretical and empirical literature regarding affect dysregulation and its relations with childhood sexual abuse and PTSD. We then describe a new affect-management group for adult survivors of childhood sexual abuse that is based on a stage approach to the treatment of trauma. This group emphasizes skill acquisition, symptom reduction, and patient stabilization.

    Violence against women has become a frequent occurrence. In Israel, some 200,000 women are subjected to various types of violence by their intimate partners annually. Routine screening for intimate partner violence is endorsed by the Ministry of Health in Israel; however, screening rates in health-care settings remain problematic. This study aimed to examine whether the model based on the Theory of Reasoned Action (TRA) succeeds in predicting women's intention to comply with screening for intimate partner violence. A questionnaire based on the literature review and research model was administered to a convenience sample of 200 married women. Although only 4.5% (n?=?9) of respondents were screened for violence at various health-care institutions over the past year, 75% (n?=?150) of women declared that they intend to cooperate with screening. A positive correlation was found between women's marriage duration, beliefs concerning violence, attitudes towards screening, family member support for compliance with screening-and women's intention to comply with screening. The TRA succeeds in partially predicting women's intention to comply with screening. PMID:23577975

    This study had two purposes: (i) to explore differences in sexual function between women with gynecological or rectal cancer after related pelvic-area treatments and women without cancer; and (ii) to investigate the relationships among body image, anxiety and depression, sexual relationship power, sexual self-schema, and female sexual function. The participants (n = 139) were recruited through Internet cancer support groups and women's health organizations in the USA. Six structured questionnaires were mailed, and the data were analyzed using descriptive and inferential statistics. The results showed that women with gynecological or rectal cancer had significantly worse sexual function than women without cancer. Having gynecological/rectal cancer and a negative sexual self-schema were significantly related to poor sexual function. Furthermore, sexual self-schema moderated the relationship between sexual relationship power and female sexual function. Healthcare providers could give more attention to sexual issues in women who have undergone treatment for gynecological or rectal cancer, especially for those with a negative sexual self-schema and high sexual relationship power, which might improve these women's quality of life.

    Objectives To characterize the impact of uterine leiomyomas (fibroids) in a racially diverse sample of women in the United States. Study Design A total of 968 women (573 White, 268 African-American, 127 other races) aged 29–59 with self-reported symptomatic uterine leiomyomas participated in a national survey. We assessed diagnosis, information seeking, attitudes about fertility, impact on work, and treatment preferences. Frequencies and percentages were summarized. Chi-square test was used to compare age groups. Results Women waited an average of 3.6 years before seeking treatment for leiomyomas, and 41% saw two or more healthcare providers for diagnosis. Almost a third of employed respondents (28%) reported missing work due to leiomyoma symptoms, and 24% felt that their symptoms prevented them from reaching their career potential. Women expressed desire for treatments that do not involve invasive surgery (79%), preserve the uterus (51%), and preserve fertility (43% of women under 40). Conclusions Uterine leiomyomas cause significant morbidity. When considering treatment, women are most concerned about surgical options, especially women under 40 who want to preserve fertility.

    Studies suggest that occupational voice users have a greater incidence of vocal issues than the general population. Women have been found to experience vocal health problems more frequently than men, regardless of their occupation. Traditionally, it has been assumed that differences in the laryngeal system are the cause of this disproportion. Nevertheless, it is valuable to identify other potential gender distinctions which may make women more vulnerable to voice disorders. A search of the literature was conducted for gender-specific characteristics which might impact the vocal health of women. This search can be used by healthcare practitioners to help female patients avoid serious vocal health injuries, as well as to better treat women who already suffer from such vocal health issues.

    Background: Gender medicine requires a global analysis of an individual's life. Menopause and ageing induce variations of some cardiometabolic parameters, but, it is unknown if this occurs in a sex-specific manner. Here, some markers of oxidative stress, systemic inflammation, and endothelial dysfunction are analysed in men younger and older than 45 years and in pre- and postmenopausal women. Methods: Serum and plasma sample were assayed for TNF-α and IL-6, malondialdehyde and protein carbonyls and for methylated arginines using ELISA kits, colorimetric methods and capillary electrophoresis. Results: Before body weight correction, men overall had higher creatinine, red blood cells and haemoglobin and lower triglycerides than women. Men younger than 45 years had lower levels of TNF-α and malondialdehyde and higher levels of arginine than age-matched women, while postmenopausal women had higher IL-6 concentrations than men, and higher total cholesterol, triglycerides, creatinine and IL-6 levels than younger women. Men younger than 45 years had lower total cholesterol and malondialdehyde than older men. After correction, some differences remained, others were amplified, others disappeared and some new differences emerged. Moreover, some parameters showed a correlation with age, and some of them correlated with each other as functions of ageing and ageing/menopausal status. Conclusions: Ageing/menopausal status increased many more cardiovascular risk factors in women than ageing in men, confirming that postmenopausal women had increased vascular vulnerability and indicating the need of early cardiovascular prevention in women. Sex-gender differences are also influenced by body weight, indicating as a matter of debate whether body weight should be seen as a true confounder or as part of the causal pathway. PMID:26941571

    Social support is critical for women dealing with intimate partner violence (IPV).When support from their informal sources, such as family, friends, and neighbours, is limited, women tend to access services provided by health professionals, social workers, and settlement workers. In this qualitative descriptive study, community leaders who were also first-generation immigrants describe the complexities of immigrant women's access to and use of formal supports to deal with IPV in Canada.The findings show that a number of factors negatively shape the experiences of these women: lack of familiarity with services, inappropriate services and intervention strategies, lack of culturally and linguistically appropriate services, lack of portability and coordination of services, confidentiality concerns, and discriminatory and racist practices embedded in services and service delivery. In order to improve care for women dealing with IPV in the post-migration context, health professionals must collaborate with social workers and settlement workers to address structural barriers that limit women's access to and use of formal social support.

    African Americans and overweight or obese women are at increased risk for excessive gestational weight gain (GWG) and postpartum weight retention. Interventions are needed to promote healthy GWG in this population; however, research on exercise and nutritional barriers during pregnancy in African American women is limited. The objective of this qualitative study is to better inform intervention messages by eliciting information on perceptions of appropriate weight gain, barriers to and enablers of exercise and healthy eating, and other influences on healthy weight gain during pregnancy in overweight or obese African American women. In-depth interviews were conducted with 33 overweight or obese African American women in Columbia, South Carolina. Women were recruited in early to mid-pregnancy (8–23 weeks gestation, n = 10), mid to late pregnancy (24–36 weeks, n = 15), and early postpartum (6–12 weeks postpartum, n = 8). Interview questions and data analysis were informed using a social ecological framework. Over 50 % of women thought they should gain weight in excess of the range recommended by the Institute of Medicine. Participants were motivated to exercise for personal health benefits; however they also cited many barriers to exercise, including safety concerns for the fetus. Awareness of the maternal and fetal benefits of healthy eating was high. Commonly cited barriers to healthy eating include cravings and availability of unhealthy foods. The majority of women were motivated to engage in healthy behaviors during pregnancy. However, the interviews also uncovered a number of misconceptions and barriers that can serve as future intervention messages and strategies. PMID:22527762

    Diseases of women that are due to their gender specific roles and responsibilities result from cultural and social factors prevalent in the environs. World Health Organization has put special emphasis on research need regarding gender related factors for diseases disproportionately affecting women in developing countries. The objective of this write up was to determine the prevalence of depression and the associated risk factors among adult women in Pakistan. PubMed was searched using key words depression, risk factors, women and Pakistan. Out of 20 initially retrieved articles, 12 were directly related to depression and its risk factors among Pakistani women within Pakistani geographical context. Women in Pakistan are vulnerable to poor mental health due to marriage related issues, domestic violence, verbal or physical abuse by in-laws, stressful life and poor social conditions. Women in their perinatal period are more at risk of depression due to pregnancy related concerns. PMID:23930875

    2013-01-01

    Black women in the United States are disproportionately affected by obesity, with almost two-thirds considered obese based on body mass index. Obesity has been directly linked to cardiovascular morbidity and mortality in black women. Therefore, understanding contributors to the genesis of obesity in black women is imperative. While biologic differences likely result in varying obesity prevalence across racial/ethnic groups, behaviors such as post-partum weight retention and limited leisure-time physical activity, may especially contribute to obesity in black women. Black women also appear to be particularly susceptible to cultural, psychosocial, and environmental factors that can promote weight gain. Therapeutic interventions are being tailored to specifically address these social determinants of health and to foster lifestyle modification; however, more work is needed to understand barriers to behavior change for black women. Knowledge gaps also remain in identifying mechanisms by which pharmacologic and surgical treatments for obesity modify cardiovascular risk in black women. PMID:24159367

    Women's reactions to three types of sexually explicit materials were examined. Ninety-six female undergraduates completed questionnaires measuring previous exposure to pornography, past history of coercive sexual experiences, attitudes toward feminism, hostility toward men, adversarial sexual beliefs, and rape myth acceptance. They were then randomly assigned to one of four conditions: (a) erotica, (b) nonviolent pornography, (c) violent pornography, and (d) control. They viewed 50 slides during each of two 30-minute sessions, completed a measure of mood disturbance, and evaluated each slide. The erotica was evaluated positively, while the pornography was evaluated negatively, and the violent pornography was evaluated more negatively than the other three conditions. Mood disturbance increased significantly from pre- to postexposure in the violent and nonviolent pornography conditions only. In addition, women with past coercive sexual experiences evaluated pornography more negatively and erotica more positively than women who had no such experience. PMID:2275894

    The ability to produce appropriate physiological and psychological responses to stressful situations depends on accurate recognition and appraisal of such situations. Such ability is also important for proper emotion regulation. A number of studies have suggested that the medial prefrontal cortex (mPFC) plays a significant role in emotion regulation, as well as in the control of physiological endpoints of emotion regulation such as the hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system (ANS). Further, recent work has suggested that men and women may differ in these mechanisms of neural control of emotion regulation. Here, we examined the role of the human mPFC in self-report, ANS, and HPA stress reactivity by testing a group of participants with damage to this region (9 women and 9 men), a brain damaged comparison group (6 women and 6 men), and healthy comparison participants (27 women and 27 men) on an orthostatic challenge and the Trier Social Stress Test (TSST). The mPFC participants showed heightened self-reported stress in response to the TSST. In women, mPFC damage led to an increased cortisol response to the TSST. By contrast, in men, greater volume of mPFC damage was correlated with a decreased cortisol response. Finally, men with mPFC damage showed altered autonomic control of the heart (higher heart rate and lower high frequency heart rate variability) during an orthostatic challenge. These findings support the idea that the mPFC is involved in the regulation of physiological and psychological responses to stress and that this regulation may differ between men and women.

    The current study examined the association between affect and self-reported alcohol intoxication in women with bulimia nervosa (BN; N=133). Participants completed a two-week ecological momentary assessment protocol. Momentary global positive affect (PA) and negative affect (NA), as well as the facets of NA (fear, guilt, hostility and sadness), were measured. Forty-five participants endorsed that they "got drunk" during the study period. Daily mean and variability of global PA and NA were compared between days with self-reported alcohol intoxication and days without self-reported alcohol intoxication. Trajectories of affect were modeled prior to and following episodes of self-reported alcohol intoxication. There were no differences in the mean or variability of PA or NA on days characterized by self-reported alcohol intoxication compared to days with no self-reported alcohol intoxication (ps>0.05). PA decreased significantly prior to self-reported alcohol intoxication and remained stable afterwards. There were no changes in global NA before or after self-reported alcohol intoxication, but an examination of the facets of NA showed that sadness increased following episodes of self-reported alcohol intoxication. These findings showed only partial support for a negative reinforcement model of alcohol use in women with BN. PMID:27111214

    Objective African American women present an understudied population in menopause research, yet face greater post-menopausal challenges associated with mortality than their white peers. We investigated the effect of a mild-intensity aerobic exercise training program on markers of mortality risk in both pre- and post-menopausal African American women. Methods 16 pre- and 19 post-menopausal women underwent 6 months of mild-intensity aerobic exercise training. Measurements included markers of blood lipid and glucose profile, inflammation, kidney function, vascular health and aerobic fitness before and after the exercise intervention. Results Before the exercise intervention the pre- and post-menopausal groups only differed in terms of age, LDL, and total cholesterol levels, with the latter two being higher in the post-menopausal group. Both triglycerides and markers of early stage endothelial dysfunction (CD62E+ endothelial microparticles) improved in both groups with aerobic exercise training. Aerobic fitness, glomerular filtration rate, body mass index, plasma glucose levels, and markers of late stage endothelial dysfunction (CD31+/CD42b? endothelial microparticles) only improved in the pre-menopausal group. Conclusions Mild-intensity aerobic exercise training was successful in improving some markers of cardiovascular disease and mortality in post-menopausal women. Higher levels of exercise intensity or perhaps additional interventions may need to be considered in this population to further decrease mortality risk. PMID:24193297

    A major component of a woman's ability to resist assaults by strangers versus acquaintances lies in the social and cognitive context in which she is engaged with the perpetrator and within which she must recognize potential threat before engaging in a behavioral response. This paper presents questionnaire and focus group findings of heterosexual college sorority women's social contexts, perceived risks, responses, and psychological barriers to protecting themselves from sexual aggression threat by fraternity acquaintances. Several social and cognitive factors, including alcohol consumption and psychological barriers, were related to projected responses to sexual aggression. Participants in general held a high sense of invulnerability to victimization and an optimistic belief in their ability to resist sexual aggression. Several differences between previously victimized and nonvictimized women also emerged. PMID:25705073

    Body height and other body attributes of humans may be associated with a diverse range of social outcomes such as attractiveness to potential mates. Despite evidence that each parameter plays a role in mate choice, we have little understanding of the relative role of each, and relationships between indices of physical appearance and general health. In this study we tested relationships between immune function and body height of young men and women. In men, we report a non-linear relationship between antibody response to a hepatitis-B vaccine and body height, with a positive relationship up to a height of 185 cm, but an inverse relationship in taller men. We did not find any significant relationship between body height and immune function in women. Our results demonstrate the potential of vaccination research to reveal costly traits that govern evolution of mate choice in humans and the importance of trade-offs among these traits.

    Payne, Benjamin Luke; Bro-Jørgensen, Jakob

    2016-05-01

    Despite increasing evidence that climatic changes are having a widespread effect on the global distribution and abundance of wildlife [1, 2], the key question of whether the ranges of species that are already threat-listed are likely to be disproportionately affected lacks quantitative assessment. According to the "small-range climate-hypersensitivity hypothesis," we predict small range size to be directly linked to large climate-induced range reduction. Antelopes, an exemplary macroecological model due to their striking ecological diversity and species richness, present an ideal opportunity to test this. Here we provide the first empirical evidence that climate change will cause a disproportionate decline in African antelopes with small geographic ranges, which places the most threatened taxa in double jeopardy. This substantiates our theoretical expectation that the link between small range size and large climate-induced range reduction is a general phenomenon. Our empirically based models also allow specific recommendations for mitigating climate-induced species declines. Gap analysis shows high priorities for antelope conservation to include creation of new protected areas in the horn of Africa and Liberia, as well as improved connectivity between existing protected areas. Predicted extinction of four species unable to reach areas with suitable climatic conditions by 2080 moreover highlights a potentially important role for ex situ conservation. The study emphasizes the urgent need to incorporate climate change into the IUCN threat assessment by extending the timeframe over which population trends are assessed [3]. PMID:27133868

    The aim of this study was to compare the effect of a cycling training programme performed at intensity corresponding to the lowest value of the respiratory quotient (RQ) versus at intensity corresponding to the ventilatory threshold (VT), on body composition and health-related parameters in overweight women. Thirty-two sedentary obese women (27-42 years old) were studied in a randomized trial of either RQ (n = 17) or VT (n = 15). RQ and VT training sessions were equalized by time (60 min) and performed in a cycloergometer. Anthropometry, body composition, lipid profile, glucose, basal metabolic rate (BMR) and fitness (maximal oxygen uptake) were evaluated before and after 12 weeks of intervention. Body weight, body mass index, fatness and fitness were improved in both groups (P<0·001). Triglycerides (TG) levels decreased only in response to RQ (P<0·001) and fat-free mass (FFM) to VT (P = 0·002). No differences were observed between groups. Both exercise intensities seem to be effective for improving health in overweight women. However, low-intensity compared with the high-intensity exercise training appears to have additional benefits on TG levels and to maintenance of FFM. PMID:23898989

    Smoking is a well-known risk factor for cardiovascular disease, although understanding of the pathophysiological mechanism is incomplete. The effect of heavy smoking, for more than 20 years and of 20 cigarettes per day, on aortic stiffness was studied in women (n = 23, age range 43-61 years) and men (n = 21, age range 43-61 years) who smoked but were otherwise healthy and compared with a healthy reference population that did not smoke. Aortic stiffness (beta) was calculated from the diameter and the pulsatile diameter change determined non-invasively using an ultrasonic echo-tracking system and blood pressure obtained by the auscultatory method. The results showed that aortic diameter did not differ in smoking males (P = 0.974) or in smoking females (P = 0.361). Aortic stiffness was increased in the female (P = 0.041) but not male smokers (P = 0.222). Systolic, mean and diastolic blood pressure in the men and women who smoked did not differ from those in the healthy reference population. In conclusion, this investigation shows increased aortic stiffness in female but not in male smokers. It indicates that the aorta of women might be more vulnerable to smoking with regard to stiffening and degeneration than the aorta of men. PMID:9347193

    2014-01-01

    Background: Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder among fertile women. Studies show reduced quality of life, anxiety, depression, body dissatisfaction, eating disorder, and sexual dysfunction, but the etiology of these disturbs remains still debated. The aim of our study is to verify whether this hyperandrogenic syndrome characterizes a strong psycho(patho)logical personality. Method: Sixty PCOS subjects (mean age 25.8 ± 4.7 years) were evaluated by anthropometric, metabolic, hormonal, clinical, and psychological parameters. After the certainty of the diagnosis of PCOS, the Rorschach test, according to Exner’s comprehensive system (CS) and the Millon Clinical Multiaxial Inventory-III (MCMI-III) were administered to each patient. The control group, on which the comparison was carried out, was composed by 40 healthy and aged compared women who were exclusively administered the Rorschach test according to CS. Results: MCMI-III evidenced axis II DSM-IV personality disorders [4.1% schizoid, depressive, sadistic, negativistic (passive–aggressive), and masochistic, 6.1% avoiding, 12.2% dependent, 20.4% histrionic, 16.3% narcissistic, 2.0% obsessive–compulsive], and axis I DSM-IV psychiatric disorders: 10.2% anxiety, 2.0% somatoform disorder and bipolar disorder, 16.3% major depressive disorder. Finally, we found 44.9% delusional disorder and 4.1% thought disorder. Rorschach test’s results show 53.1% reduced coping abilities and social skills, 55.1% depression, 30.6% perceptual distortion and cognitive slippage, 24.5% constantly alert and worry, 8.1% at risk for suicide, and finally about 50% of our patients had chronic stress. Conclusion: PCOS women have relevant personality and psychiatric disorders, when compared with normal subjects. PMID:25429283

    We sought to provide a historical overview of methods, models, and data used in the environmental justice (EJ) research literature to measure proximity to environmental hazards and potential exposure to their adverse health effects. We explored how the assessment of disproportionate proximity and exposure has evolved from comparing the prevalence of minority or low-income residents in geographic entities hosting pollution sources and discrete buffer zones to more refined techniques that use continuous distances, pollutant fate-and-transport models, and estimates of health risk from toxic exposure. We also reviewed analytical techniques used to determine the characteristics of people residing in areas potentially exposed to environmental hazards and emerging geostatistical techniques that are more appropriate for EJ analysis than conventional statistical methods. We concluded by providing several recommendations regarding future research and data needs for EJ assessment that would lead to more reliable results and policy solutions. PMID:21836113

    When compared with their older counterparts, younger women are more likely to have depressive symptoms because they more often experience interrupted work history and a heavy childrearing burden. The purposes of the present study were 1) to investigate the possible association of psychosocial work environment with psychological distress and 2) to examine the way by which communication and support in the workplace affect to psychological distress among young women. We studied 198 women aged 20 to 39 yr in a cross-sectional study. The Kessler Scale-10 (K10 Scale) was used to examine psychological distress. In employees who experienced interpersonal conflict, those who had little or no conversations with their supervisor and/or co-workers had a significantly increased risk of psychological distress (OR, 4.2), and those who received little or no support from their supervisor and/or co-workers had a significantly increased risk of psychological distress (OR, 3.8) compared to those who had more frequent communication and received more support. Harmonious communication in the workplace can help prevent psychological distress among employees, which in turn may enable them to be satisfied with their work. PMID:26320729

    Syndemic risk is an ecological construct, defined by co-occurring interdependent socio-environmental, interpersonal and intrapersonal determinants. We posited syndemic risk to be a function of violence, substance use, perceived financial hardship, emotional distress and self-worth among women with and at-risk for HIV in an impoverished urban community. In order to better understand these interrelationships, we developed and validated a system dynamics (SD) model based upon peer-reviewed literature; secondary data analyses of a cohort dataset including women living with and at-risk of HIV in Bronx, NY (N = 620); and input from a Bronx-based community advisory board. Simulated model output revealed divergent levels and patterns of syndemic risk over time across different sample profiles. Outputs generated new insights about how to effectively explore multicomponent multi-level programs in order to strategically develop more effective services for this population. Specifically, the model indicated that effective multi-level interventions might bolster women's resilience by increasing self-worth, which may result in decreased perceived financial hardship and risk of violence. Overall, our stakeholder-informed model depicts how self-worth may be a major driver of vulnerability and a meaningful addition to syndemic theory affecting this population. PMID:26370203

    Women with a history of childhood sexual abuse (CSA) are at greater risk for experiencing sexual problems in their adult lives. Yet, little is known about the possible role of cognitive and affective mechanisms in the development of sexual arousal difficulties in this population. This study investigated the role of pre-existing affect (affect prior to exposure to sexual stimuli) on genital responses, subjective sexual arousal, and affect elicited during the presentation of erotic film excerpts in a community sample of 25 women with and 25 women without a history of CSA. The CSA group showed greater pre-existing negative affect and smaller genital responses to the erotic film stimuli compared to the NSA group. Findings support a moderating effect of CSA, in that pre-existing negative affect was associated with strength of genital responses in the NSA but not in the CSA group. The results did not support a mediation model of pre-existing negative affect as an explanation for smaller physiological sexual responses in the CSA group. Taken together, the findings suggest that pre-existing affect may be more relevant for women with no history of CSA and call for more research on factors implicated in impaired sexual responses in women with a history of CSA.

    The HIV/AIDS epidemic continues to disproportionately affect racial and ethnic minority groups and women in the United States. Prevention research suggests that reduced alcohol use and increased HIV testing are associated with lower incidence of HIV transmission among high-risk populations. Multivariable logistic regression analyses of the 2009 National Health Interview Survey data were performed for a national sample of 15,470 adult women to examine the relationship between alcohol use and likelihood of HIV testing. There is a significant association between level of alcohol use and HIV testing. Women who identified as heavy drinkers and moderate drinkers were significantly less likely to report ever testing for HIV. Findings add to the limited literature on the association between alcohol use and HIV testing behaviors among women. Given the incidence of HIV among women, this study highlights the importance of HIV testing, especially for alcohol-using women. PMID:26238036

    2011-01-01

    Recent progress with declines in mortality in some high income countries has obscured the fact that for the majority of women worldwide who are newly diagnosed, breast cancer is a neglected disease in the context of other numerically more frequent health problems. For this growing majority, it is also an orphan disease, in that detailed knowledge about tumor characteristics and relevant host biology necessary to provide even basic care are absent. With the possible exception of nutritional recommendations, current international cancer policy and planning initiatives are irrelevant to breast cancer. The progress that has occurred in high income countries has come at extraordinary fiscal expense and patient toxicity, which of themselves suggest non-relevance to women and health care practitioners in middle and low income countries. The implications of these circumstances seem clear: if the promise of the now 60 year-old Declaration of Human Rights, that the fruits of medical science accrue to all mankind, is to be realized with respect to breast cancer, a basic and translational global research initiative should be launched.

    This study examined the impact of co-occurring Axis I disorders on drug treatment outcomes of drug-dependent pregnant women. Participants (N = 106) were women who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for opioid dependence and were receiving methadone. Based on DSM-IV Axis I criteria, participants were categorized into three groups: (1) absence of mood/anxiety disorder (ND, n = 29), (2) primary mood disorder (MD, n = 39), or (3) primary anxiety disorder (AD, n = 38). Demographically, the groups were similar. The MD group was significantly more likely to be positive for drugs while in treatment compared with both the ND and AD groups. The MD and AD groups had more psychosocial impairment and higher incidence of suicidal ideation compared with the ND group. Interestingly, the AD group spent more days in treatment compared with the ND or MD group. These findings highlight the need to treat co-occurring Axis I disorders, particularly given the higher relapse risk for those with mood disorders. PMID:17175395

    Abortion has been a hotly contested political issue since the mid 1960s, when states began liberalizing their abortion laws. Recent Supreme Court rulings, such as Rust vs. Sullivan, the retirement of two liberal Supreme Court justices and the battle over Louisiana's abortion legislation have created new fervor on both fronts of the battle. All health care providers who care for women need to be cognizant of the current abortion laws and the factors that influence the abortion decision. These factors include the different levels of health risk and financial implications posed by continued pregnancy or abortion. Historically, numerous court cases have influenced women's health care, and reviews of several significant cases are provided. The Webster vs. Reproductive Health Services decision was the first case that directly challenged the Roe vs. Wade decision. The Webster decision enables states to have greater authority in writing their own abortion laws. Individual state laws can vary greatly, so it is vitally important for providers to know and understand the laws of their state. PMID:1798604

    Endometrial receptivity is still questioned today in women with endometriosis. The aim of this study was to assess the endometrial receptivity gene signature in patients with different stages of endometriosis by investigating transcriptomic modifications of their endometrium using the endometrial receptivity array (ERA) test. A prospective, interventional multicentre pilot trial was designed and implemented in two university-affiliated infertility units from Belgium and Spain. Gene expression microarray was used to diagnose the receptivity status by quantifying the expression of 238 specific genes directly related to human endometrial receptivity. Unsupervised hierarchical clustering showed no clustering of samples based on endometriosis stages. Two subgroups of samples clustered together corresponding on the day of the cycle in which the biopsy was taken (day 18 versus days 19-20). None of the 238 genes present in the ERA array were significantly over- or under- expressed in any of different stages of the disease compared with controls. Minimal differences were found when looking at the functional profile, suggesting that the possible effect from a clinical point of view may be meaningless. Endometrial receptivity gene signature during the implantation window does not vary significantly among patients with endometriosis even considering different stages compared with healthy women.

    Purpose Obesity is associated with impaired quality of life (QoL), but less is known about physical activity. We investigated how decreases in body mass index (BMI) and increases in activity affect obesity-specific QoL and potential gender differences in associations. Methods In a large worksite-randomized trial of a multilevel intervention on diet and physical activity behaviors, we conducted a cohort analysis at two years of follow-up. Self-reported activity and Obesity and Weight-Loss Quality Of Life (OWLQOL) were analyzed for individual-level associations using linear mixed models accounting for random worksite effects. Results Gender modified the BMI-OWLQOL relationship, so analyses were conducted for males and females separately. Adjusting for demographic confounders, baseline OWLQOL, and several worksite-level variables including intervention arm, a 1.9 unit decrease in BMI (the interquartile range) was associated with an OWLQOL increase of 1.7 (95% CI: 1.2, 2.2) in males and 3.6 (95% CI: 3.2, 4.0) in females. Similarly, a 23 unit increase in physical activity score was associated with an OWLQOL increase of 0.9 (95% CI: 0.5, 1.4) in males and 1.6 (95% CI: 1.0, 2.3) in females. Physical activity associations were attenuated when adjusting for change in BMI, but remained significant for women (mean BMI 27.8 kg/m2). Conclusions This is the first study to demonstrate that increasing physical activity may improve obesity-specific QoL to a greater extent in women, particularly among overweight women, independent of BMI. Results may inform the design of interventions tailored to women targeting well-being through messages of increasing physical activity. PMID:23504523

    Neural tube defects (NTDs) include anomalies of the brain (anencephaly and encephalocele) and spine (spina bifida). Even with ongoing mandatory folic acid fortification of enriched cereal grain products, the U.S. Preventive Services Task Force recommends that women of childbearing potential consume a daily supplement containing 400 µg-800 µg of folic acid. Women with a prior NTD-affected pregnancy have an increased risk for having another NTD-affected pregnancy, and if they are planning another pregnancy, the recommendation is that they consume high-dosage folic acid supplements (4.0 mg/day) beginning ≥4 weeks before conception and continuing through the first 12 weeks of pregnancy. To learn whether folic acid supplementation (from multivitamins or single- ingredient supplements) was commonly used during pregnancy by women with a previous NTD-affected pregnancy, supplement use was assessed among a convenience sample of women with a previous NTD-affected pregnancy who participated in the National Birth Defects Prevention Study (NBDPS), a case-control study of major birth defects in the United States. Characteristics of women who previously had an NTD-affected pregnancy and whose index pregnancy (pregnancy included in NBDPS) was either affected by an NTD (N = 17) (i.e., recurrence-cases) or resulted in a live-born infant without a major birth defect (N = 10) (i.e., recurrence-controls) were assessed. Taking a supplement that included folic acid was more common among recurrence-control mothers (80%) than recurrence-case mothers (35%). The recommendation that women should take folic acid supplements just before and during early pregnancy is not being followed by many women and offers an opportunity for NTD prevention, especially among women who are at a higher risk because they have had a previous pregnancy affected by an NTD.

    Adherence to antiretroviral therapy (ART) is crucial for effective treatment, but can be quite complex. Non-adherence can adversely affect treatment outcomes. Although many studies have been done on adherence in the general population, few have included HIV-positive pregnant and postpartum women in resource-constrained settings. This review assessed the evidence on adherence among these groups of women. A systematic search of databases was completed between June and July 2011. Both qualitative and quantitative studies were included. Eighteen studies from a total of 6622 satisfied the inclusion criteria that included inter alia facilitators and barriers to adherence. This review highlighted that there is still no consensus on the definition and measurement of adherence; also multiple factors can affect a woman's ability to adhere to ART. Some of the barriers and facilitators identified were similar in both the type of study (qualitative and quantitative) and among the various countries. Findings indicated that the few studies in this population are conducted primarily in resource-rich settings. Such paucity of information warrants urgent attention; thus targeted research is needed to provide insight on adherence within this population. PMID:23970743

    Inflammatory pathways are increasingly recognized to be tightly associated with insulin resistance in humans. The promoter region of the adiponectin gene--Apm1--encompasses consensus sequences for glucocorticosteroid receptor responsive element. Dexamethasone induced downregulation of adiponectin secretion in vitro, whereas prednisolone administration increased circulating adiponectin concentrations. As previous studies have demonstrated an inverse relationship between corticosteroid-binding globulin (CBG), body mass index, and insulin resistance, we studied whether CBG could explain cortisol-to-adiponectin relationship. One hundred twenty-two healthy subjects were enrolled in a cross-sectional study. Plasma CBG and serum cortisol concentration were measured by radioimmunoassay. The cortisol-to-CBG ratio was used to calculate free cortisol. An RIA kit (Linco Research, St Louis, MO) was used to measure adiponectin levels. Insulin resistance was calculated using the homeostatis model of assessment (HOMA) value. Circulating adiponectin was associated with serum CBG ( r = 0.38, P < .00001), both in men ( r = 0.26, P = .03, n = 79) and women ( r = 0.48, P = .003, n = 43), and with insulin resistance (HOMA index) ( r = -0.30, P < .0001) in both. Free cortisol correlated negatively with adiponectin only in women ( r = -0.32, P = .04), but not in men ( r = 0.01, P = .89). Serum CBG concentration was significantly lower among men in the lowest quartile of adiponectin when compared with the remaining subjects (37.3 +/- 5.7 vs 40.6 +/- 5.1, P = .016), whereas men in the highest quartile of adiponectin showed significantly increased free cortisol index (14.2 +/- 3.3 vs 12.2 +/- 3.1, P = .039). Women in the lowest quartile of adiponectin also displayed significantly lower CBG concentration than that present in the remaining subjects (38.6 +/- 6.9 vs 44.4 +/- 5.5, P = .016), whereas free cortisol index was not significantly different across adiponectin quartiles ( P = .1). In a stepwise regression analysis, body mass index ( P = .0011), CBG ( P = .0047), and sex ( P = .04) contributed to 15%, 8%, and 3%, respectively, of adiponectin variance. Using CBG as dependent variable, both adiponectin ( P = .0002) and fasting cortisol ( P = .019) contributed to 14% and 4%, respectively, of CBG variance. In summary, circulating adiponectin, CBG concentration, and fasting cortisol were significantly interrelated in healthy subjects. A significant sexual dimorphism exists in this association.

    This paper reports a newly described form of skeletal dysplasia affecting Brazilian hair sheep of the Cabugi breed. This breed is characterized by having a short head and in some cases the animals are smaller and more compact than sheep of similar breeds. Lambs born with craniofacial abnormalities and dwarfism that die at 2-6 months of age are frequent in this breed. In a flock of 68 ewes and three rams of the Cabugi breed, 134 lambs were born over a 4-year period. Of these, 14 (10.4%) had marked cranial abnormalities and dwarfism and died or were humanely destroyed, 43 (32%) had a normal face and 77 (57.5%) had the short face characteristic of the breed. Dwarf lambs were much smaller than normal, with short legs, a domed head with retruded muzzle and protruded mandible, sternal deformities and exophthalmic eyes situated more laterally in the face than normal. Microscopical examination of long bones of the limbs, bones of the base of the skull and vertebrae showed no lesions. Bones from four affected lambs and one control lamb were macerated for morphometric examination. Although the length of the spinal cord was similar, there was disproportionate shortening of the appendicular bones, particularly the distal segments. Thus the disease was defined as a skeletal dysplasia characterized by craniofacial deformity and disproportionate dwarfism. It is suggested that the disease is inherited as an incomplete dominant trait. The shortened face, which is a feature of the Cabugi breed, may represent the heterozygous state and the more severe, often lethal, dwarfism may occur in homozygotes. PMID:24447571

    Background Endometriosis is a complex disease affecting 10–15% of women at reproductive age. Very few genes are known to be altered in this pathology. RIP140 protein is an important cofactor of oestrogen receptor and many other nuclear receptors. Targeting disruption experiments of nrip1 gene in mice have demonstrated that nuclear receptor interacting protein 1 gene (nrip1), the gene encoding for rip140 protein, is essential for female fertility. Specifically, mice null for nrip1 gene are viable, but females are infertile because of complete failure of mature follicles to release oocytes at ovulation stage. The ovarian phenotype observed in mice devoid of rip140 closely resembles the luteinized unruptured follicle (LUF) syndrome that is observed in a high proportion of women affected of endometriosis or idiopathic infertility. Here we present a preliminary work that analyses the role of NRIP1 gene in humans. Methods We have sequenced the complete coding region of NRIP1 gene in 20 unrelated patients affected by endometriosis. We have performed genetic association studies by using the DNA variants identified during the sequencing process. Results We identified six DNA variants within the coding sequence of NRIP1 gene, and five of them generated amino acid changes in the protein. We observed that three of twenty sequenced patients have specific combinations of amino-acid variants within the RIP140 protein that are poorly represented in the control population (p = 0.006). Moreover, we found that Arg448Gly, a common polymorphism located within NRIP1 gene, is associated with endometriosis in a case-control study (59 cases and 141 controls, pallele positivity test = 0.027). Conclusion Our results suggest that NRIP1 gene variants, separately or in combinations, might act as predisposing factors for human endometriosis. PMID:16131398

    The authors examined the self-regulatory strategies and subjective well-being of students recently diagnosed with eating disorders, at-risk students, and individuals without eating disorders. Fifty-six college students were individually interviewed regarding their use of self-regulatory strategies to lose and maintain their weight; they also completed the Extended Satisfaction with Life Scale (V. C. Alfonzo, D. B. Allison, D. E. Rader, & B. S. Gorman, 1996) and the Positive and Negative Affect Scale (D. Watson, L. A. Clarck, & A. Tellegen, 1988). As hypothesized, students with eating disorders reported more self-regulated strategies for managing their weight, a lower level of life satisfaction, and higher levels of negative affect than did at-risk students or individuals with normal weights. At-risk students reported higher levels of self-regulation and negative affect than did the students with normal weights. These findings may be useful for parents and health practitioners providing care to college students, who must be made aware of the signs and symptoms of these disorders. PMID:12943188

Vegetable protein sources, by contrast, are low in saturated fat and without associated cholesterol. We have therefore assessed the effect on serum lipids of raising the protein intake by 5% using a cereal protein, barley protein, as part of a standard therapeutic diet. Twenty-three hypercholesterolemic men and postmenopausal women completed a randomized crossover study comparing a bread enriched with either barley protein or calcium caseinate [30 g protein, 8374 kJ (2000 kcal)] taken separately as two 1-mo treatment phases with a minimum 2-wk washout. Body weight and diet history were collected weekly during each treatment. Fasting blood samples were obtained at wk 0, 2, and 4. Palatability, satiety, and compliance were similar for both the barley protein- and casein-enriched breads, with no differences between the treatments in effects on serum LDL cholesterol or C-reactive protein, measures of oxidative stress, or blood pressure. Nevertheless, because no adverse effects were observed on cardiovascular risk factors, barley protein remains an additional option for raising the protein content of the diet. PMID:20668250

    Objective This randomized, cross-over trial was designed to investigate the metabolic and appetitive responses to skipping breakfast in overweight women who were habitual breakfast Eaters or Skippers. Design and Methods Nine Eaters and nine Skippers were studied on two separate days during which subjects ate breakfast (B), or had no breakfast (NB), followed by a standard lunch meal 4 hours later. Blood sampling for hormones and metabolites was performed after lunch and appetite was rated throughout the day. Results Interactions between day and habitual breakfast pattern were seen for Area Under the Curve (AUC) for insulin and free fatty acids (FFA). Both insulin (p=0.020) and FFA (p=0.023) AUC were higher on the NB day for Eaters, but similar on both days for Skippers. Eaters had higher pre-lunch hunger AUC on the NB day (p=0.015) as well as lower pre-lunch satiety AUC under both conditions (p=0.019). Conclusion Overall, this study showed that the adverse effects of skipping breakfast (higher insulin and FFA responses to lunch, increased hunger and decreased satiety) were found primarily in habitual breakfast eaters. This suggests that meal skipping may have enhanced effects in habitual Eaters due to entrainment of metabolic and appetitive regulatory systems. PMID:25755093

    The hydrogen absorption and desorption characteristics of the hydrogenation disproportionation desorption and recombination (HDDR) process on scrap sintered neodymium-iron-boron (NdFeB) type magnets have been investigated. At each stage of the process, the microstructural changes have been studied using high resolution scanning electron microscopy. It was found that the disproportionation reaction initiates at grain boundaries and triple points and then propagates towards the centre of the matrix grains. This process was accelerated at particle surfaces and at free surfaces produced by any cracks in the powder particles. However, the recombination reaction appeared to initiate randomly throughout the particles with no apparent preference for particle surfaces or internal cracks. During the hydrogenation of the grain boundaries and triple junctions, the disproportionation reaction was, however, affected by the much higher oxygen content of the sintered NdFeB compared with that of the as-cast NdFeB alloys. Throughout the entire HDDR reaction the oxidised triple junctions (from the sintered structure) remained unreacted and hence, remained in their original form in the fine recombined microstructure. This resulted in a very significant reduction in the proportion of cavitation in the final microstructure and this could lend to improved consolidation in the recycled magnets.

    Osteoporosis is a disease characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to bone fragility and an increased susceptibility to fractures; the early stage of decreased bone density is called osteopenia. More than 200 million people are affected and about 50% of post-menopausic women are expected to develop the disease. Osteoporosis, osteopenia and periodontal disease have in common several risk factors, being hyperthyroidism and smoking habits the most important ones. There is scarce information in the literature about the association between periodontal disease and osteoporosis and/or osteopenia. Some works suggest that osteoporotic women are susceptible to a higher loss of periodontal insertion, alveolar bones, and teeth. Thirty adult post-menopausic women were studied; some of them were healthy (control group) and the rest of them were undergoing some stage of osteoporosis or osteopenia. All the subjects were healthy, non-smokers, not having dental implants, and with communitarian periodontal index higher than 1(CPI > 1). Samples of saliva and gingival crevice fluid were extracted with calibrated micro-capillaries and deposited on Si reflectors. Known amounts of Ga were added to the samples in order to act as internal standard for quantification by the total reflection x-ray fluorescence technique. Experimental concentrations of several elements (P, S, Cl, K, Ca, Cr, Fe, NI, Cu, and Zn) were determined. The concentration of some elements in saliva showed different behavior as compared to gingival crevice fluid. Some critical elements of bone composition, such as Ca and Zn, present very distinguishable behavior. Improvements in the statistics are required for a better assessment of a routine method and to establish some correlation with periodontal disease. TXRF seems to be a promising method to evaluate the evolution of osteoporosis.

    Background: Physical activity and mental health could be affected by osteoporosis and various therapeutic options such as calcitonin may influence Quality Of Life (QOL) of these patients with Low Bone Density (LBD). Objectives: This study aimed to evaluate the effect of nasal calcitonin on QOL in post menopause women with LBD. Patients and Methods: This clinical trial study was performed on one hundred and fifteen menopause women with LBD less than 1 SD in Bone Mineral Densitometry (BMD) referred to Baqiyatallah Hospital in Tehran, Iran, during 2009 - 2010. They were assigned to receive 200 IU calcitonin nasal spray along with calcium (1000 mg) and vitamin D (400 IU) for 6 months. Quality of life was assessed by Short-Form 36 (SF-36) questionnaire (Persian-validated version). Results: The mean age (± SD) of the participants was 58.75 ± 8.15 years. Intranasal spray of calcitonin increased QOL scores significantly (88.05 ± 15.63 vs. 92.15 ± 13.22, P value = 0.000). Bone mineral density of spine was increased from 0.834 ± 0.11 to 0.12 ± 0.852 and this difference in BMD of lumbar spine was statistically significant (P value: 0.003) but not significant in femur’s BMD (P value = 0.061). In comparison with BMD indexes, The QOL scores especially Mental Health domain changes had only a significant correlation with the changes of total T score in BMD (P = 0.031, Coefficient Correlation = 0.248). Conclusions: It seems that nasal spray of calcitonin can effectively improve QOL of women with LBD and QOL changes were not influenced by clinical or para-clinical alteration. Mental health domain must be more considered in further studies as a predicting domain for Health-Related Quality of Life (HR-QOL) changes. PMID:26421180

  11. Factors affecting the use of prenatal care by non-western women in industrialized western countries: a systematic review

    2013-01-01

    Background Despite the potential of prenatal care for addressing many pregnancy complications and concurrent health problems, non-western women in industrialized western countries more often make inadequate use of prenatal care than women from the majority population do. This study aimed to give a systematic review of factors affecting non-western women’s use of prenatal care (both medical care and prenatal classes) in industrialized western countries. Methods Eleven databases (PubMed, Embase, PsycINFO, Cochrane, Sociological Abstracts, Web of Science, Women’s Studies International, MIDIRS, CINAHL, Scopus and the NIVEL catalogue) were searched for relevant peer-reviewed articles from between 1995 and July 2012. Qualitative as well as quantitative studies were included. Quality was assessed using the Mixed Methods Appraisal Tool. Factors identified were classified as impeding or facilitating, and categorized according to a conceptual framework, an elaborated version of Andersen’s healthcare utilization model. Results Sixteen articles provided relevant factors that were all categorized. A number of factors (migration, culture, position in host country, social network, expertise of the care provider and personal treatment and communication) were found to include both facilitating and impeding factors for non-western women’s utilization of prenatal care. The category demographic, genetic and pregnancy characteristics and the category accessibility of care only included impeding factors. Lack of knowledge of the western healthcare system and poor language proficiency were the most frequently reported impeding factors. Provision of information and care in women’s native languages was the most frequently reported facilitating factor. Conclusion The factors found in this review provide specific indications for identifying non-western women who are at risk of not using prenatal care adequately and for developing interventions and appropriate policy aimed at improving their prenatal care utilization.

    This research synthesis examined HIV/AIDS surveillance and health care financing data and reviewed relevant research literature to describe HIV epidemiology, outcomes, funding, and contributing factors to the HIV epidemic in the Southern USA with particular focus on a group of Southern states with similar demographic and disease characteristics and comparable HIV epidemics (Alabama, Georgia, Florida, Los Angeles, Mississippi, North Carolina, South Carolina, Tennessee, and Texas). These states are hereafter referred to as "targeted Southern states." Eight of the 10 states with the highest HIV diagnosis rates in 2011 were in the Southern USA; six were targeted states. Forty-nine percent of HIV diagnoses were in the South in 2011, which contains only 37% of the US population. The targeted states region had the highest HIV diagnosis rate than any other US region in 2011. The South was also found to have the highest HIV-related mortality and morbidity rates in the USA. The high levels of poverty, HIV-related stigma, and STDs found in the South, particularly in the targeted Southern states, likely contribute to greater HIV incidence and mortality. The disproportionate impact of HIV in the South, particularly among targeted states, demonstrates a critical need to improve HIV prevention and care and address factors that contribute to HIV disease in this region.

    Photolysis of an aryl sulfide containing 5,6-dihydropyrimidine (1) at 350 nm produces high yields of thymidine and products resulting from trapping of 5,6-dihydrothymidin-5-yl radical by O2 or thiols. Thymidine is believed to result from disproportionation of the radical pair originally generated from C-S bond homolysis in 1 on the microsecond timescale, which is significantly shorter than other photochemical transformations of modified nucleotides into their native forms. Duplex DNA containing 1 is destabilized, presumably due to disruption of π-stacking. Incorporation of 1 within the binding site of the restriction endonuclease EcoRV, provides a photochemical switch for turning on the enzyme's activity. In contrast, 1 is a substrate for endonuclease VIII and serves as a photochemical off switch for this base excision repair enzyme. Modification 1 also modulates the activity of the 10–23 DNAzyme despite its incorporation into a non-duplex region. Overall, dihydropyrimidine 1 shows promise as a tool that provides spatiotemporal control over DNA structure on the miscrosecond tiimescale. PMID:23940105

    PURPOSE Religious traditions call their members to care for the poor and marginalized, yet no study has examined whether physicians’ religious characteristics are associated with practice among the underserved. This study examines whether physicians’ self-reported religious characteristics and sense of calling in their work are associated with practice among the underserved. METHODS This study entailed a cross-sectional survey by mail of a stratified random sample of 2,000 practicing US physicians from all specialties. RESULTS The response rate was 63%. Twenty-six percent of US physicians reported that their patient populations are considered underserved. Physicians who were more likely to report practice among the underserved included those who were highly spiritual (multivariate odds ratio [OR] = 1.7; 95% confidence interval [CI], 1.1–2.7], those who strongly agreed that their religious beliefs influenced their practice of medicine (OR = 1.6; 95% CI, 1.1–2.5), and those who strongly agreed that the family in which they were raised emphasized service to the poor (OR = 1.7; 95% CI, 1.0–2.7). Physicians who were more religious in general, as measured by intrinsic religiosity or frequency of attendance at religious services, were much more likely to conceive of the practice of medicine as a calling but not more likely to report practice among the underserved. CONCLUSIONS Physicians who are more religious do not appear to disproportionately care for the underserved. PMID:17664502

    Background: Fibromyalgia is a syndrome characterized by the presence of widespread chronic pain. People with fibromyalgia report lower levels of Positive Affect and higher levels of Negative Affect than non-fibromyalgia peers. The Positive and Negative Affect Schedule (PANAS)–a widely used questionnaire to assess two core domains of affect; namely ‘Positive Affect’ and ‘Negative Affect’ –has a controversial factor structure varying across studies. The internal structure of a measurement instrument has an impact on the meaning and validity of its score. Therefore, the aim of the present study was to assess the structural construct validity of the PANAS in adult women with fibromyalgia. Methods: This population-based cross-sectional study included 442 adult women with fibromyalgia (age: 51.3 ± 7.4 years old) from Andalusia (Southern Spain). Confirmatory factor analyses were conducted to test the factor structure of the PANAS. Results: A structure with two correlated factors (Positive Affect and Negative Affect) obtained the best fit; S-B χ2 = 288.49, df = 155, p < .001; RMSEA = .04; 90% CI of RMSEA = (.036, .052); the best fit SRMR = .05; CFI = .96; CAIC = −810.66, respectively. Conclusions: The present study demonstrates that both Positive Affect and Negative Affect are core dimensions of affect in adult women with fibromyalgia. A structure with two correlated factors of the PANAS emerged from our sample of women with fibromyalgia from Andalusia (Southern Spain). In this model, the amount of variance shared by Positive Affect and Negative Affect was small. Therefore, our findings support to use and interpret the Positive Affect and Negative Affect subscales of the PANAS as separate factors that are associated but distinctive as well. PMID:27047704

    It has been suggested, mainly through animal studies, that exposure to high noise levels may be associated with lower birth weight, reduced gestational length and other adverse reproductive outcomes. Few studies have been done on humans to show this association. The Air Force employs pregnant women in areas where there is a high potential for exposure to high noise levels. This study proposes a method to determine if there is an association between high frequency noise levels or = 115 dBA and adverse reproductive outcomes through a review of records and self-administered questionnaires in a case-comparison design. Prevelance rates will be calculated and a multiple logistic regression analysis computed for the independent variables that can affect reproduction.

    Social and public health scientists are increasingly interested in applying system dynamics theory to improve understanding and to harness the forces of change within complex, multilevel systems that affect community intervention implementation, effects, and sustainability. Building a system dynamics model based on ethnographic case study has the advantage of using empirically documented contextual factors and processes of change in a real-world and real-time setting that can then be tested in the same and other settings. System dynamics modeling offers great promise for addressing persistent problems like HIV and other sexually transmitted epidemics, particularly in complex rapidly developing countries such as China. We generated a system dynamics model of a multilevel intervention we conducted to promote female condoms for HIV/sexually transmitted infection (STI) prevention among Chinese women in sex work establishments. The model reflects factors and forces affecting the study's intervention, implementation, and effects. To build this conceptual model, we drew on our experiences and findings from this intensive, longitudinal mixed-ethnographic and quantitative four-town comparative case study (2007-2012) of the sex work establishments, the intervention conducted in them, and factors likely to explain variation in process and outcomes in the four towns. Multiple feedback loops in the sex work establishments, women's social networks, and the health organization responsible for implementing HIV/STI interventions in each town and at the town level directly or indirectly influenced the female condom intervention. We present the conceptual system dynamics model and discuss how further testing in this and other settings can inform future community interventions to reduce HIV and STIs. PMID:24084394

    The importance of X chromosome in the aetiology of premature ovarian failure (POF) is well-known but in many cases POF still remains idiopathic. Chromosome aneuploidy increase is a physiological phenomenon related to aging, but the role of low-level sex chromosome mosaicism in ovarian function is still undiscovered. Standard cytogenetic analysis was carried out in a total of 269 patients affected by POF: 27 chromosomal abnormalities were identified, including X chromosome and autosomal structural and numerical abnormalities. In 47 patients with 46,XX karyotype we performed interphase FISH using X alpha-satellite probe in order to identify X chromosome mosaicism rate. Aneuploidy rate in the patient group was significantly higher than the general population group. These findings underline the importance of X chromosome in the aetiology of POF and highlight the potential role of low-level sex chromosome mosaicism in ovarian aging that may lead to a premature onset of menopause.

    Affective style (AS) and communication deviance (CD) have been suggested as markers of dysfunctional family environments that may be associated with psychiatric illness. Studies have focused mainly on parental responses during family interactions when an offspring is the identified patient. The present study is unique in examining AS and CD in mothers with unipolar depression, bipolar disorder, or chronic physical illness, and in normal controls. The sample consisted of 64 mothers with children ages 8 to 16. Unipolar mothers were more likely to show negative AS than were any other maternal group. There were no group differences for CD. Chronic stress, few positive life events, and single parenting were associated with AS. CD was associated solely with lower socioeconomic status. Results suggest that dysfunctional interactions are determined not only by maternal psychopathology, but also by an array of contextual factors that are related to the quality of the family environment.

    Elemental sulfur (ES) is a common product of pyrite oxidation during acid mine drainage (AMD), but bacterial disproportionation of ES has not previously been inferred in acidic environments. Pore water profiles were collected seasonally within a coal-mine waste deposit, Minnehaha, in Southwest Indiana that has been abandoned for over 30 years. Geochemical characterization and modeling were used to assess how the interactions between the sulfur and iron cycle are affected by seasonally dynamic hydrologic conditions. Pore waters were collected seasonally and concentrations of Fe-species and sulfur isotopic compositions of sulfate were determined. Additionally, a sediment core was collected and used for sequential extraction and isotopic characterization of solid-phase sulfur species including elemental sulfur (δ34Ses), pyrite (δ34Spy), acid-volatile sulfides, water-soluble sulfates, and acid-soluble sulfates. The dominant disulfide phase was found to be pyrite through x-ray diffraction of an additional sediment core. Sulfur isotope fractionations between δ34Spy and δ34Ses (Δ34Ses-py) of up to -33% are inferred to indicate bacterial disproportionation of ES in the presence of a non-limiting sulfide 'scrub' Fe(III). The initial isotopic composition, following formation from pyrite oxidation, is inferred from δ34Spy, found to be ≈ 8.75% at the study site. Although ES has previously been found to accumulate in acidic Fe(III)-rich pore waters, ES is typically assumed to account for less than 1% of the oxidized sulfur pool and measurements of the ES isotopic composition are often neglected during field studies of acid AMD. The pore waters at Minnehaha were seasonally suboxic with sharp transitions from Fe(III)- to Fe(II)- dominated conditions near the phreatic surface. It is hypothesized that the sulfide product of ES disproportionation, fractionated by up to -8.6%, is immediately re-oxidized to ES near the redox gradient via reaction with Fe(III). Sulfide re-oxidation allows for the accumulation of isotopically light ES that can then become subject to further sulfur disproportionation. A mass-balance model for ES, incorporating seasonally varying rates for pyrite oxidation, ES disproportionation, and ES oxidation, was developed in order to determine the potential and conditions necessary for extensive recycling of ES by disproportionating bacteria to produce ES enriched in 32S compared to the pyrite source. Simulations run for 32 seasonal cycles resulted in a Δ34Ses-py of -16.4.% and an ES concentration of 170 ppm, which is consistent with average values obtained from the sediment core. The findings suggest that ES disproportionation is likely an important microbial process in AMD that should be considered at similar mining waste deposits experiencing seasonally varying hydrologic conditions and that Δ34Ses-py can be used to estimate multiple cycles of ES disproportionation in oxic settings where the original source of ES is pyrite oxidation.

    Background: Bilateral risk-reducing salpingo-oophorectomy (BRRSO) is the only effective way of reducing mortality from ovarian cancer. This study investigates uptake of BRRSO in 700 BRCA1/2 mutation carriers from Greater Manchester. Methods: Dates of last follow-up and BRRSO were obtained, and the following variables were investigated: ovarian cancer risk/gene, age and breast cancer history. The date of the genetic mutation report was the initiation for KaplanMeier analysis. Results: The uptake of BRRSO in BRCA1 mutation carriers was 54.5% (standard error 3.6%) at 5 years post testing compared with 45.5% (standard error 3.2%) in BRCA2 mutation carriers (P=0.045). The 4059 years category showed the greatest uptake for BRRSO and uptake was significantly lower in the over 60?s (P<0.0001). Of the unaffected BRCA1 mutation carriers, 65% (standard error 5.1%) opted for surgery at 5 years post-testing compared with 41.1% (standard error 5.1%) in affected BRCA1 mutation carriers (P=0.045). Conclusion: The uptake of BRRSO is lower in women previously affected by breast cancer and in older women. As there is no efficient method for early detection of ovarian cancer, uptake should ideally be greater. Counselling should be offered to ensure BRCA1/2 mutation carriers make an informed decision about managing their ovarian cancer risk. PMID:22187038

    All living organisms are linked through trophic relationships with resources and consumers, the balance of which determines overall ecosystem stability and functioning. Ecological research has identified a multitude of mechanisms that contribute to this balance, but ecologists are now challenged with predicting responses to global environmental changes. Despite a wealth of studies highlighting likely outcomes for specific mechanisms and subsets of a system (e.g., plants, plant-herbivore or predator-prey interactions), studies comparing overall effects of changes at multiple trophic levels are rare. We used a combination of experiments in a grassland system to test how biomass at the plant, herbivore and natural enemy (parasitoid) levels responds to the interactive effects of two key global change drivers: warming and nitrogen deposition. We found that higher temperatures and elevated nitrogen generated a multitrophic community that was increasingly dominated by herbivores. Moreover, we found synergistic effects of the drivers on biomass, which differed across trophic levels. Both absolute and relative biomass of herbivores increased disproportionately to that of plants and, in particular, parasitoids, which did not show any significant response to the treatments. Reduced parasitism rates mirrored the profound biomass changes in the system. These findings carry important implications for the response of biota to environmental changes; reduced top-down regulation is likely to coincide with an increase in herbivory, which in turn is likely to cascade to other fundamental ecosystem processes. Our findings also provide multitrophic data to support the general concern of increasing herbivore pest outbreaks in a warmer world. PMID:22815763

  4. Women, e-waste, and technological solutions to climate change.

    2014-01-01

    In this paper, we argue that a crossover class of climate change solutions (which we term "technological solutions") may disproportionately and adversely impact some populations over others. We begin by situating our discussion in the wider climate discourse, particularly with regard to the Millennium Development Goals (MDGs) and the Basel Convention. We then suggest that many of the most attractive technological solutions to climate change, such as solar energy and electric car batteries, will likely add to the rapidly growing stream of electronic waste ("e-waste"). This e-waste may have negative downstream effects on otherwise disenfranchised populations. We argue that e-waste burdens women unfairly and disproportionately, affecting their mortality/morbidity and fertility, as well as the development of their children. Building on this, we claim that these injustices are more accurately captured as problems of recognition rather than distribution, since women are often institutionally under-acknowledged both in the workplace and in the home. Without institutional support and representation, women and children are deprived of adequate safety equipment, health precautions, and health insurance. Finally, we return to the question of climate justice in the context of the human right to health and argue for greater inclusion and recognition of women waste workers and other disenfranchised groups in forging future climate agreements.

    To identify the energy source that drives the biosynthesis of amino acids, lipids, and nucleotides from glucose, we calculated the free energy change due to redox disproportionation of the substrate carbon of: (1) 26-carbon fermentation reactions and (2) the biosynthesis of amino acids and lipids of E. coli from glucose. The free energy (cal/mmol of carbon) of these reactions was plotted as a function of the degree of redox disproportionation of carbon (disproportionative electron transfers (mmol)/mmol of carbon). The zero intercept and proportionality between energy yield and degree of redox disproportionation exhibited by this plot demonstrate that redox disproportionation is the principal energy source of these redox reactions (slope of linear fit = -10.4 cal/mmol of disproportionative electron transfers). The energy and disproportionation values of E. coli amino acid and lipid biosynthesis from glucose lie near this linear curve fit with redox disproportionation accounting for 84% and 96% (and ATP only 6% and 1 %) of the total energy of amino acid and lipid biosynthesis, respectively. These observations establish that redox disproportionation of carbon, and not ATP, is the primary energy source driving amino acid and lipid biosynthesis from glucose. In contrast, we found that nucteotide biosynthesis involves very little redox disproportionation, and consequently depends almost entirely on ATP for energy. The function of sugar redox disproportionation as the major source of free energy for the biosynthesis of amino acids and lipids suggests that sugar disproportionation played a central role in the origin of metabolism, and probably the origin of life.

These observations establish that redox disproportionation of carbon, and not ATP, is the primary energy source driving amino acid and lipid biosynthesis from glucose. In contrast, we found that nucleotide biosynthesis involves very little redox disproportionation, and consequently depends almost entirely on ATP for energy. The function of sugar redox disproportionation as the major source of free energy for the biosynthesis of amino acids and lipids suggests that sugar disproportionation played a central role in the origin of metabolism, and probably the origin of life.

    Erectile dysfunction negatively affects men and women in relationships; however, the subjective experience of erectile dysfunction and phosphodiesterase-type 5 inhibitor therapy remains poorly understood. The authors therefore characterized participants' subjective understanding of erectile dysfunction and phosphodiesterase-type 5 inhibitor therapy using individual interviews with affected heterosexual men (n = 58) and women (n = 65). Responses were characterized by 6 psychosocial domains: explanation of the experience, emotional responses, socially expected responses, value of sex, communication with the partner, and treatment expectations. The findings may aid clinicians in relating to men with erectile dysfunction and thus potentially improve effectiveness of therapy. PMID:24274107

    Self-harm and suicide attempts occur at elevated rates among individuals with bulimia nervosa, particularly among those who have experienced childhood abuse. This study investigated the potential mediating roles of emotion dysregulation and affective intensity in the relationship between these variables in 125 women with bulimia nervosa. Analyses revealed that emotion dysregulation mediated the relationship between sexual and emotional abuse with both self-harm and suicide attempts. Negative affective intensity mediated the relationship between abuse and suicide attempts. The findings may advance the understanding of mechanisms underlying suicide-related behaviors in women with bulimia nervosa who experienced abuse and suggest potential clinical targets.

    Background Despite evidence that bright light can improve mood, the neurobiology remains poorly understood. Some evidence implicates the catecholamines. In the present study, we measured the effects of transiently decreasing dopamine (DA) synthesis on mood and motivational states in healthy women with mild seasonal mood changes who were tested in either bright or dim light. Methods On 2 test days, participants slept overnight in a light-controlled room. On the morning of each session, half of the participants awoke to gradual increases of bright light, up to 3000 lux, and half to dim light (10 lux). For all participants, DA was reduced on 1 of the test days using the acute phenylalanine/tyrosine depletion (APTD) method; on the other day, they ingested a nutritionally balanced control mixture (BAL). Beginning 4 hours postingestion, participants completed subjective mood questionnaires, psychological tests and a progressive ratio breakpoint task during which they worked for successive units of $5. Results Thirty-two women participated in our study. The APTD lowered mood, agreeableness, energy and the willingness to work for monetary reward. The effects on energy and motivation were independent of light, while the effects on mood and agreeableness were seen in the dim condition only, being prevented by bright light. Limitations Acute phenylalanine/tyrosine depletion might affect systems other than DA. The sample size was small. Conclusion These results suggest that increased DA function may be responsible for some of the beneficial effects of light, while adding to the evidence that the neurobiology of mood and motivational states can be dissociated.

    Background: Pregnancy is associated with unfavorable metabolic profile, which might in turn result in adverse pregnancy outcomes. The current study was designed to evaluate the effects of calcium plus Vitamin D administration on metabolic status and pregnancy outcomes in healthy pregnant women. Methods: This randomized double-blind placebo-controlled clinical trial was performed among 42 pregnant women aged 18–40 years who were at week 25 of gestation. Subjects were randomly allocated to consume either 500 mg calcium-200 IU cholecalciferol supplements (n = 21) or placebo (n = 21) for 9 weeks. Blood samples were obtained at the onset of the study and after 9-week trial to determine related markers. Post-delivery, the newborn's weight, length, and head circumference were measured during the first 24 h after birth. Results: Consumption of calcium-Vitamin D co-supplements resulted in a significant reduction of serum high-sensitivity C-reactive protein levels compared with placebo (−1856.8 ± 2657.7 vs. 707.1 ± 3139.4 μg/mL, P = 0.006). We also found a significant elevation of plasma total antioxidant capacity (89.3 ± 118.0 vs. −9.4 ± 164.9 mmol/L, P = 0.03), serum 25-hydroxyvitamin D (2.5 ± 3.5 vs. −1.7 ± 1.7 ng/mL, P < 0.0001), and calcium levels (0.6 ± 0.6 vs. −0.1 ± 0.4 mg/dL, P < 0.0001). The supplementation led to a significant decrease in diastolic blood pressure (−1.9 ± 8.3 vs. 3.1 ± 5.2 mmHg, P = 0.02) compared with placebo. No significant effect of calcium-Vitamin D co-supplements was seen on other metabolic profiles. We saw no significant change of the co-supplementation on pregnancy outcomes as well. Conclusions: Although calcium-Vitamin D co-supplementation for 9 weeks in pregnant women resulted in improved metabolic profiles, it did not affect pregnancy outcomes. PMID:27076887

  11. Combination of inositol and alpha lipoic acid in metabolic syndrome-affected women: a randomized placebo-controlled trial

    2013-01-01

    Background Inositol has been reported to improve insulin sensitivity since it works as a second messenger achieving insulin-like effects on metabolic enzymes. The aim of this study was to evaluate the inositol and alpha lipoic acid combination effectiveness on metabolic syndrome features in postmenopausal women at risk of breast cancer. Methods A six-month prospective, randomized placebo-controlled trial was carried out on a total of 155 postmenopausal women affected by metabolic syndrome at risk of breast cancer, the INOSIDEX trial. All women were asked to follow a low-calorie diet and were assigned randomly to daily consumption of a combination of inositol and alpha lipoic acid (77 pts) or placebo (78 pts) for six months. Primary outcomes we wanted to achieve were both reduction of more than 20% of the HOMA-IR index and of triglycerides serum levels. Secondary outcomes expected were both the improvement of high-density lipoprotein cholesterol levels and the reduction of anthropometric features such as body mass index and waist-hip ratio. Results A significant HOMA-IR reduction of more than 20% was evidenced in 66.7% (P <0.0001) of patients, associated with a serum insulin level decrease in 89.3% (P <0.0000). A decrease in triglycerides was evidenced in 43.2% of patients consuming the supplement (P <0.0001). An increase in HDL cholesterol (48.6%) was found in the group consuming inositol with respect to the placebo group. A reduction in waist circumference and waist-hip ratio was found in the treated group with respect to the placebo group. Conclusions Inositol combined with alpha lipoic acid can be used as a dietary supplement in insulin-resistant patients in order to increase their insulin sensitiveness. Daily consumption of inositol combined with alpha lipoic acid has a significant bearing on metabolic syndrome. As metabolic syndrome is considered a modifiable risk factor of breast tumorigenesis, further studies are required to assess whether inositol combined with alpha lipoic acid can be administered as a dietary supplement in breast cancer primary prevention.

    Rapid urbanization is a key driver of the unique set of health risks facing urban populations. One of the most critical health hazards facing urban women is intimate partner violence (IPV). In post-conflict urban areas, women may face an even greater risk of IPV. Yet, few studies have examined the IPV experiences of urban-dwelling, conflict-affected women, including those who have been internally displaced. This study qualitatively examined the social and structural characteristics of the urban environment that contributed to the IPV experiences of women residing in post-conflict Abidjan, Côte d'Ivoire. Ten focus groups were conducted with men and women, both internally displaced (IDPs) and non-displaced. Lack of support networks, changing gender roles, and tensions between traditional gender norms and those of the "modern" city were reported as key contributors to IPV. Urban poverty and with it unemployment, food insecurity, and housing instability also played a role. Finally, IDPs faced heightened vulnerability to IPV as a result of displacement and discrimination. The relationship between economic strains and IPV are similar to other conflict-affected settings, but Abidjan's urban environment presented other unique characteristics contributing to IPV. Understanding these factors is crucial to designing appropriate services for women and for implementing IPV reduction interventions in urban areas. Strengthening formal and informal mechanisms for help-seeking, utilizing multi-modal interventions that address economic stress and challenge inequitable gender norms, as well as tailoring programs specifically for IDPs, are some considerations for IPV program planning focused on conflict-affected women in urban areas.

    Social and public health scientists are increasingly interested in applying system dynamics theory to improve understanding and to harness the forces of change within complex, multilevel systems that affect community intervention implementation, effects, and sustainability. Building a system dynamics model based on ethnographic case study has the advantage of using empirically documented contextual factors and processes of change in a real world and real time setting that can then be tested in the same and other settings. System dynamics modeling offers great promise for addressing persistent problems like HIV and other sexually transmitted epidemics, particularly in complex rapidly developing countries like China. We generated a system dynamics model of a multilevel intervention we conducted to promote female condoms (FC) for HIV/STI prevention among Chinese women in sex-work establishments. The model reflects factors and forces affecting the study’s intervention implementation and effects. To build this conceptual model, we drew on our experiences and findings from this intensive, longitudinal mixed ethnographic and quantitative four-town comparative case study (2007–2012) of the sex-work establishments, the intervention conducted in them, and factors likely to explain variation in process and outcomes in the four towns. Multiple feedback loops in the sex-work establishments, women’s social networks, and the health organization responsible for implementing HIV/STI interventions in each town and at the town level directly or indirectly influenced the FC intervention. We present the conceptual system dynamics model and discuss how further testing in this and other settings can inform future community interventions to reduce HIV and STIs. PMID:24084394

    Satisfaction with sexual activity i.e. sexual satisfaction and the importance of sexuality and affection were analysed using data from the German “Interdisciplinary Longitudinal Study of Adult Development” (ILSE). At three measurement points, 1993–1995, 1997–1998, and 2004–2006 i.e. subjects' ages of 63, 67, and 74 years, participants' reports about their affection and sexual activity were collected. The sample of completed records used for this study consisted of 194 urban non-institutionalised participants, 68% male, all living with partners. Median levels of sexual satisfaction were reported, fluctuating between the measurement points of ages 63 to 74. Between baseline, first and second follow-up no differences were found in levels of sexual satisfaction, though at measurement points age 63 and 67 women were more satisfied than men. When measured at age 74, affection was given a higher priority than sexual activity. Although men and women reported similar priorities, sexual activity and affection were more important for men than for women. Satisfaction within the relationship can be predicted by the importance of affection, but not by that of sexual activity. Our results confirm the thesis of the ‘second language of sexuality’: for humans in their later years affection seems to be more important than for younger individuals. PMID:25369193

    Although negative affect (NA) has been identified as a common trigger for bulimic behaviors, findings regarding NA following such behaviors have been mixed. This study examined reciprocal associations between NA and bulimic behaviors using real-time, naturalistic data. Participants were 133 women with bulimia nervosa (BN) according to the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders who completed a 2-week ecological momentary assessment protocol in which they recorded bulimic behaviors and provided multiple daily ratings of NA. A multilevel autoregressive cross-lagged analysis was conducted to examine concurrent, first-order autoregressive, and prospective associations between NA, binge eating, and purging across the day. Results revealed positive concurrent associations between all variables across all time points, as well as numerous autoregressive associations. For prospective associations, higher NA predicted subsequent bulimic symptoms at multiple time points; conversely, binge eating predicted lower NA at multiple time points, and purging predicted higher NA at 1 time point. Several autoregressive and prospective associations were also found between binge eating and purging. This study used a novel approach to examine NA in relation to bulimic symptoms, contributing to the existing literature by directly examining the magnitude of the associations, examining differences in the associations across the day, and controlling for other associations in testing each effect in the model. These findings may have relevance for understanding the etiology and/or maintenance of bulimic symptoms, as well as potentially informing psychological interventions for BN.

    Depression and anxiety are significant mental health issues that affect urban, ethnically diverse, impoverished women disproportionately. This study sought to identify social determinants of mental health and barriers to help-seeking for this population. Using community based participatory research and focus groups, sixty-one Black, Hispanic, and White women identified economic, family, cultural, and neighborhood issues as perceived determinants of their depression/anxiety. They identified practical, psychosocial, and cultural barriers to their help-seeking behavior. These results can promote women's health by fostering an understanding of social factors as perceived determinants of depression/anxiety and shaping practice and policy initiatives that foster positive aggregate outcomes.

    Yemeni breast-feeding beliefs and practices are discussed in relation to the ritual status of Muslim women. It is argued that the existing socio-religious perspective of women in Yemen is expressed in, and reinforced by, their attitudes to breast-feeding. Yemeni women consider breastfeeding to be a powerful, but potentially destructive force. The Quran defines the worth of both women and breast-feeding, and this is upheld by the attitudes of contemporary Yemeni society. The practices and beliefs associated with the reproductive and menstrual cycles, indicate that these female functions are considered hedged with danger and ambiguity. Breast-feeding, which is connected to both cycles, is no exception. Traditional breast-feeding beliefs and practices are best understood within the wider context of the perceived place and ritual status of women in Yemeni society. PMID:6526683

    Introduction HIV-affected women and couples often desire children and many accept HIV risk in order to attempt pregnancy and satisfy goals for a family. Risk reduction strategies to mitigate sexual and perinatal HIV transmission include biomedical and behavioural approaches. Current efforts to integrate HIV and reproductive health services offer prime opportunities to incorporate strategies for HIV risk reduction during pregnancy attempts. Key client and provider values about services to optimize pregnancy in the context of HIV risk provide insights for the design and implementation of large-scale “safer conception” programmes. Discussion Through our collective experience and discussions at a multi-disciplinary international World Health Organization–convened workshop to initiate the development of guidelines and an algorithm of care to support the delivery of services for HIV-affected women and couples attempting pregnancy, we identified four values that are key to the implementation of these programmes: (1) understanding fertility care and an ability to identify potential fertility problems; (2) providing equity of access to resources enabling informed decision-making about reproductive choices; (3) creating enabling environments that reduce stigma associated with HIV and infertility; and (4) creating enabling environments that encourage disclosure of HIV status and fertility status to partners. Based on these values, recommendations for programmes serving HIV-affected women and couples attempting pregnancy include the following: incorporation of comprehensive reproductive health counselling; training to support the transfer and exchange of knowledge between providers and clients; care environments that reduce the stigma of childbearing among HIV-affected women and couples; support for safe and voluntary disclosure of HIV and fertility status; and increased efforts to engage men in reproductive decision-making at times that align with women's desires. Conclusions Programmes, policies and guidelines that integrate HIV treatment and prevention, sexual and reproductive health and fertility care services in a manner responsive to user values and preferences offer opportunities to maximize demand for and use of these services. For HIV-affected women and couples attempting pregnancy, the provision of comprehensive services using available tools – and the development of new tools that are adaptable to many settings and follow consensus recommendations – is a public health imperative. The impetus now is to design and deliver value-driven inclusive programming to achieve the greatest coverage and impact to reduce HIV transmission during pregnancy attempts. PMID:26643454

    Exclusive breastfeeding (EBF) is optimal for infant health and is associated with decreased risk of mother-to-child HIV transmission compared with mixed feeding of breast milk and other foods. To investigate why many women stop EBF before the recommended 6 months, maternal and infant health and infant-feeding data were collected from 177 HIV-infected and 177-uninfected Zambian women regularly from 34 weeks gestation to 16 weeks postpartum. Despite strong support for good breastfeeding practice, only 37% of women were still EBF at week 16. Factors significantly associated with shorter duration of EBF were primiparity, maternal systemic illness, and infant length at 6 weeks. The results suggest that the association of EBF with lower rates of mother-to-child HIV transmission may not be causal but may be secondary to the reduced duration of EBF associated with poor maternal or infant health. Programs supporting EBF should include support for maternal health. PMID:16113015

    The results of the Global Survey of Physicists draw attention to the need to focus on factors other than representation when discussing the situation of women in physics. Previous studies of women in physics have mostly focused on the lack of women in the field. This study goes beyond the obvious shortage of women and shows that there are much deeper issues. For the first time, a multinational study was conducted with approximately 15,000 respondents from 130 countries, showing that problems for women in physics transcend national borders. Across all countries, women have fewer resources and opportunities and are more affected by cultural expectations concerning child care. We show that limited resources and opportunities hurt career progress, and because women have fewer opportunities and resources, their careers progress more slowly. We also show the disproportionate effects of children on women physicists' careers. Cultural expectations about home and family are difficult to change. However, for women to have successful outcomes and advance in physics, they must have equal access to resources and opportunities.

    African American women are disproportionately affected by HIV. Some research has explored if non-disclosing men who have sex with men and women contribute to women's HIV risk. Popular media discourse tends to refer to these men as 'down low' or 'DL'. Six focus groups were conducted with 36 African American women in Washington, DC, to examine their knowledge, attitudes, beliefs and behaviours regarding DL men. Three of the focus groups were composed of HIV-positive women and three groups were composed of HIV-negative women. Data analysis reveals six central subcategories related to women's perspectives on the DL: awareness, suspicion, coping with partner infidelity (male versus female), sexual health communication, empathy and religion. No major differences were identified between the HIV-positive and HIV-negative focus groups. Findings from this study provide insight into African American women's perceptions of African American male sexuality and how these perceptions serve to influence interpersonal relationship factors and women's exposure to HIV risk.

    Young African-American women are disproportionately affected by human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) sexually transmitted infections (STI), and engage in greater sexual concurrency than other race/ethnicities. It is important to evaluate behaviors and characteristics associated with the risk of sexual concurrency, so that interventions can target factors most likely to affect positive change. An emphasis on correlates of concurrency beyond individual-level factors has been suggested. The purpose of this study, therefore, was to identify individual- and partner-level characteristics associated with sexual concurrency among high-risk, young African-American women. Data were collected from 570 African-American adolescent women (aged 15-21) recruited from a STI clinic, a family planning clinic, and a teen clinic located in Atlanta, GA from March 2002 through August 2004. Logistic regression analysis was conducted in 2012 to evaluate correlates of sexual concurrency. Results show that almost one-quarter of participants reported sexually concurrent partnerships and 28.4% suspected male partner concurrency. Logistic regression results indicated the number of lifetime sexual partners and relationship factors were the primary contributors to engaging in concurrency in this sample. These findings suggest relationship factors may be important contributors to the prevalence of sexual concurrency among young African-American women. Interventions targeted toward sexual health among young African-American women may need to specifically address partner/relationship factors. Through these findings, we hope to better understand sexual risk taking and develop strategies that would overcome barriers to existing interventions aimed at improving the sexual health outcomes of young African-American women.

    Incarcerated women are disproportionately affected by HIV and sexually transmitted infections (STIs) due to risk factors before, during, and after imprisonment. This study assessed the behavioral, social, and contextual conditions that contribute to continuing sexual risk behaviors among incarcerated women to inform the adaptation of an evidenced-based behavioral intervention for this population. Individual, in-depth interviews were conducted with 25 current and 28 former women prisoners to assess HIV/STI knowledge, perceptions of risk, intimate relationships, and life circumstances. Interviews were independently coded using an iterative process and analyzed using established qualitative analytic methods. Major themes identified in the interviews involved three focal points: individual risk (substance abuse, emotional need, self-worth, perceptions of risk, and safer sex practices); interpersonal risk (partner pressure, betrayal, and violence); and risk environment (economic self-sufficiency and preparation for reentry). These findings highlight the critical components of HIV/STI prevention interventions for incarcerated women. PMID:25204565

    Introduction Women in conflict-affected countries are at risk of mental disorders such as posttraumatic stress disorder and depression. No studies have investigated the association between experiences of abuse and injustice and explosive anger amongst women in these settings, and the impact of anger on women's health, family relationships and ability to participate in development. Methods A mixed methods study including an epidemiological survey (n = 1513, 92.6% response) and qualitative interviews (n = 77) was conducted in Timor-Leste. The indices measured included Intermittent Explosive Disorder, posttraumatic stress disorder; severe distress; days out of role (the number of days that the person was unable to undertake normal activities); gender-specific trauma; conflict/violence; poverty; and preoccupations with injustice. Results Women with Intermittent Explosive Disorder (n = 184, 12.2%) were more disabled than those without the disorder (for >5 days out of role, 40.8% versus 31.5%, X2(2)  = 12.93 p = 0.0016). Multivariable associations with Intermittent Explosive Disorder, controlling for the presence of PTSD, psychological distress and other predictors in the model, included the sense of being sick (OR 1.73; 95% CI 1.08–2.77); victimization as a result of helping the resistance movement (OR 2.33, 95% CI 1.48–3.68); war-related trauma specific to being a woman (OR 1.95, 95%, CI 1.09–3.50); ongoing family violence and community conflict (OR 1.88, 95% CI 1.27–2.77); extreme poverty (OR 1.23, 95%, CI 1.08–1.39); and distressing preoccupations with injustice (relating to 2/3 historical periods, OR 2.10, 95% CI 1.35–3.28). In the qualitative study, women elaborated on the determinants of anger and its impact on their health, family and community functioning, child-rearing, and capacity to engage in development. Women reflected on the strategies that might help them overcome their anger. Conclusions Intermittent Explosive Disorder is prevalent and disabling amongst women in conflict-affected Timor-Leste, impacting on their health, child-rearing and ability to participate fully in socio-economic development.

    Eighty pregnant women (25 substance using, 55 nonusing) from an American prenatal clinic serving lower-income to working-class women responded to questionnaire measures of child-rearing attitudes. The drug users' primary substance of misuse was cocaine (68%), alcohol (16%), amphetamines (12%), or sedatives (4%); polydrug use was documented for 80% of the women. The two (user and nonuser) groups were not different on demographic (age, race, marital status, education, SES, source of income) or obstetrical factors (number of pregnancies, number of children). Drug-using women scored significantly higher on a measure of child abuse potential; more than half scored in the range of clinical criterion for extreme risk. As their babies were not yet born, no actual physical abuse was documented, only a higher potential for abuse. The subgroup who were both drug users and had lower social support scored higher on child abuse potential than all other subgroups. The drug users also had lower self-esteem scores than the nonusers. The two groups did not differ on measures of overall social support, authoritarian/democratic child-rearing beliefs, or affection for the expected baby. PMID:7836024

    Background We sought to determine the association between factors that affected clini- cal pregnancy and live birth rates in patients who underwent in vitro fertilization (IVF) and received intracytoplasmic sperm injection (ICSI) and/or laser assisted hatching (LAH), or neither. Materials and Methods In this retrospective cohort study, the records of women who underwent IVF with or without ICSI and/or LAH at the Far Eastern Memorial Hospital, Taipei, Taiwan between January 2007 and December 2010 were reviewed. We divided patients into four groups: 1. those that did not receive ICSI or LAH, 2. those that received ICSI only, 3. those that received LAH only and 4. those that received both ICSI and LAH. Univariate and multivariate analyses were performed to determine factors associated with clinical pregnancy rate and live birth rate in each group. Results A total of 375 women were included in the analysis. Oocyte number (OR=1.07) affected the live birth rate in patients that did not receive either ICSI or LAH. Mater- nal age (OR=0.89) and embryo transfer (ET) number (OR=1.59) affected the rate in those that received ICSI only. Female infertility factors other than tubal affected the rate (OR=5.92) in patients that received both ICSI and LAH. No factors were found to affect the live birth rate in patients that received LAH only. Conclusion Oocyte number, maternal age and ET number and female infertility fac- tors other than tubal affected the live birth rate in patients that did not receive ICSI or LAH, those that received ICSI only, and those that received both ICSI and LAH, respectively. No factors affected the live birth rate in patients that received LAH only. These data might assist in advising patients on the appropriateness of ICSI and LAH after failed IVF. PMID:25918590

  14. How does AIDS illness affect women's residential decisions? Findings from an ethnographic study in a Cape Town township.

    2009-06-01

    This paper explores the nature and consequences of residential decision-making for women on treatment for AIDS illness in a poor urban settlement in South Africa. Drawing on ethnographic data collected over a two-year period, it points to the subtle shifts in 'householding' practices and kinship relationships prompted by women's individual experiences and understanding of their HIV status, illness and treatment. Women's decisions to move or to arrange that other family members move can be explained by pre-existing threats to individual wellbeing or family residential security. But an HIV diagnosis can intensify a mother's thoughts and actions in relation to residential and emotional security, in particular on behalf of her children. In a context where extended periods of childcare by rural relatives is common, mothers with AIDS illness may gather all their children in their home to offer direct care, achieve intimacy and facilitate disclosure. They are likely to avoid making frequent contact with, and demands on, their elderly parents. Siblings are favoured as co-residents and confidants in disclosure, but their long-term support is contingent on reciprocity. Partners, where present, are valued for economic, social and emotional security. Women attempt to balance their children's nurturing, in the short and long term, with care of the self. Their efforts do not always succeed and can incur high costs to their wellbeing and relationships with their children. PMID:25875568

    The Non-Pneumatic Anti-Shock Garment (NASG) is a first-aid device to reduce mortality from severe obstetric hemorrhage, the leading cause of maternal mortality globally. We sought to evaluate patient characteristics associated with mortality among a cohort of women treated with the NASG in Nigeria. Data on 1,149 women were collected from 50 facilities participating in the Pathfinder International Continuum of Care: Addressing Postpartum Hemorrhage project in Nigeria from 2007–2012. Characteristics were compared using the appropriate distributional tests, and we estimated multivariable logistic regression models to control for treatment received. There were 201 deaths (17.5%). Women who died were significantly more likely to have any co-morbidity (AOR 3.63, 95% CI: 2.41–5.48), ruptured uterus (AOR 2.79, 95% CI: 1.48–5.28), macerated stillbirth (AOR 2.96, 95% CI 1.60–5.48) and to have had 6 or more previous births, (AOR 1.53, 95% CI 1.11–2.12), after adjusting for treatment received. These results suggest certain maternal conditions, particularly the presence of another life-threatening co-morbidity or macerated stillbirth, conferred a higher risk of mortality from PPH. This underscores the need for multi-system assessment and a comprehensive approach to the treatment of women with pregnancy complications. PMID:23950937

    In two scenario-based studies, we found that women and men evaluate glass-cliff positions (i.e., precarious leadership positions at organizations in crisis) differently depending on the social and financial resources available. Female and male participants evaluated a hypothetical leadership position in which they would have both social and financial resources, financial resources but no social resources, or social resources but no financial resources. Women evaluated the position without social resources most negatively, whereas men evaluated the position without financial resources most negatively. In study 2, we found that women and men considered different issues when evaluating these leadership positions. Women's evaluations and expected levels of influence as leaders depended on the degree to which they expected to be accepted by subordinates. In contrast, men's evaluations and expected levels of acceptance by subordinates depended on the degree to which they expected to be influential in the position. Our findings have implications for the understanding of the glass-cliff phenomenon and gendered leadership stereotypes. PMID:23042121

    In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed. PMID:18325482

    Although cervical cancer rates in the United States have declined sharply in recent decades, certain groups of women remain at elevated risk, including middle-aged and older women in central Appalachia. Cross-sectional baseline data from a community-based randomized controlled trial were examined to identify barriers to cervical cancer screening. Questionnaires assessing barriers were administered to 345 Appalachian women aged 40-64, years when Pap testing declines and cervical cancer rates increase. Consistent with the PRECEDE/PROCEED framework, participants identified barriers included predisposing, enabling, and reinforcing factors. Descriptive and bivariate analyses are reported, identifying (a) the most frequently endorsed barriers to screening, and (b) significant associations of barriers with sociodemographic characteristics in the sample. Recommendations are provided to decrease these barriers and, ultimately, improve rates of Pap tests among this traditionally underserved and disproportionately affected group. PMID:23179390

  20. Women and AIDS: the ethics of exaggerated harm.

    PubMed

    1996-04-01

    This article examines the way in which some biomedical ethicists have constructed sexually transmitted AIDS as a significant threat to women's health. We demonstrate that the familiar claim that 'women are the fastest growing group' -- whether of HIV-infected or of AIDS patients -- is misleading because it obscures the distinction between proportional rate of growth and absolute increase. Feminist ethicists have suggested that misogyny of a male dominated health care system has led to underreporting of women AIDS cases in order to support these feminists' claim of AIDS being a real threat to women's health. Given the apparent rarity of tertiary transmissions of AIDS, the assertion that most or even many women are at significant risk for AIDS seems wrong. Particularly disturbing in this campaign is the fact that the theme of 'risky sex' has been extended all the way to lesbians, even though their risk to acquire AIDS sexually is non-existent to miniscule. We argue that actual harm is done to women by this exaggeration of their risk of contracting AIDS sexually. The scare has led to misappropriations of scarce health care funds. AIDS disproportionately affects women who inject drugs, and who suffer other diseases, poverty and malnutrition. It would have been better to concentrate health care efforts in this area instead of 'educating' women not at risk for AIDS how to prevent the acquisition of this disease. Unjustifiable AIDS anxiety has been created in women and has resulted in millions of unnecessary HIV-tests, and many broken relationships. This anxiety has inevitably reduced the pleasure of having sex for many women. We reject the kind of 'victim ideology' that lies at the heart of this strategy which has, unfortunately, been supported by a number of influential feminist ethicists. PMID:11653248

  1. Pathways in STEM: Factors affecting the retention and attrition of talented men and women from the STEM pipeline

    Heilbronner, Nancy N.

    Many men and women who are talented in science, technology, engineering, and/or mathematics (STEM) choose not to pursue undergraduate majors or careers in these fields. To develop talents in STEM, educators must understand the factors that contribute to an individual's retention in STEM domains, as well as the factors that act as barriers to success, such as the role that gender plays in the underrepresentation of women in certain STEM fields (e.g., computer science and engineering) and changes in recent decades in the process of selecting STEM majors and careers. The purpose of this study was to explore the influences that guide decisions related to the selection of majors and occupations during high school, post-secondary education, and early careers. Survey methodology was used to explore the perceptions of 360 Science Talent Search (STS) semifinalists and finalists during the years 1987-1989 and 1997-1999, and quantitative procedures were used to analyze the data. A majority (74.2%) of STS participants majored in a STEM field in college, and most (68.6%) currently work in a STEM field. A greater percentage of men selected computer science, engineering, physics, and mathematics majors, and a greater percentage of women selected biological science and chemistry. Belief in one's ability to achieve in STEM was a predictor of STEM majors in college and STEM concentrations in graduate school, but differences were found between men's and women's self-efficacy in STEM during high school and in college, as women had lower self-efficacy. Sex was a predictor of STEM majors in college, but perceived quality of academic courses was not. STEM majors also reported more satisfaction with their STEM courses in high school and college than non-STEM majors. In a departure from the results of previous research, the reasons that men and women selected occupations were similar, as were the reasons they chose to leave or not to enter STEM. The most frequently cited reason for attrition was interest in another (non-STEM) field. Participants placed little importance on other reasons for leaving STEM that were identified in previous research, such as competition, social isolation, or financial considerations.

    Background: Low selenium status in pregnancy has been associated with a number of adverse conditions. In nonpregnant populations, the selenium status or response to supplementation has been associated with polymorphisms in dimethylglycine dehydrogenase (DMGDH), selenoprotein P (SEPP1) and the glutathione peroxidases [cytosolic glutathione peroxidase (GPx1) and phospholipid glutathione peroxidase (GPx4)]. Objective: We hypothesized that, in pregnant women, these candidate polymorphisms would be associated with selenium status in early pregnancy, its longitudinal change, and the interindividual response to selenium supplementation at 60 μg/d. Design: With the use of stored samples and data from the United Kingdom Selenium in Pregnancy Intervention (SPRINT) study in 227 pregnant women, we carried out genetic-association studies, testing for associations between selenium status, its longitudinal change, and response to supplementation and common genetic variation in DMGDH (rs921943), SEPP1 (rs3877899 and rs7579), GPx1 (rs1050450) and GPx4 (rs713041). Selenium status was represented by the concentration of whole-blood selenium at 12 and 35 wk of gestation, the concentration of toenail selenium at 16 wk of gestation, and plasma glutathione peroxidase (GPx3) activity at 12 and 35 wk of gestation. Results: Our results showed that DMGDH rs921943 was significantly associated with the whole-blood selenium concentration at 12 wk of gestation (P = 0.032), which explained ≤2.0% of the variance. This association was replicated with the use of toenail selenium (P = 0.043). In unsupplemented women, SEPP1 rs3877899 was significantly associated with the percentage change in whole-blood selenium from 12 to 35 wk of gestation (P = 0.005), which explained 8% of the variance. In supplemented women, SEPP1 rs3877899 was significantly associated with the percentage change in GPx3 activity from 12 to 35 wk of gestation (P = 0.01), which explained 5.3% of the variance. Selenium status was not associated with GPx1, GPx4, or SEPP1 rs7579. Conclusions: In agreement with previous studies, we show that the genetic variant rs921943 in DMGDH is significantly associated with selenium status in United Kingdom pregnant women. Notably, our study shows that women who carry the SEPP1 rs3877899 A allele are better able to maintain selenium status during pregnancy, and their GPx3 activity increases more with supplementation, which suggests better protection from low selenium status. The SPRINT study was registered at www.isrctn.com as ISRCTN37927591. PMID:26675765

    Background Menopausal hormone therapy (MHT) reportedly increases the risk of cognitive decline in women over age 65 y. It is unknown whether similar risks exist for recently postmenopausal women, and whether MHT affects mood in younger women. The ancillary Cognitive and Affective Study (KEEPS-Cog) of the Kronos Early Estrogen Prevention Study (KEEPS) examined the effects of up to 4 y of MHT on cognition and mood in recently postmenopausal women. Methods and Findings KEEPS, a randomized, double-blinded, placebo-controlled clinical trial, was conducted at nine US academic centers. Of the 727 women enrolled in KEEPS, 693 (95.3%) participated in the ancillary KEEPS-Cog, with 220 women randomized to receive 4 y of 0.45 mg/d oral conjugated equine estrogens (o-CEE) plus 200 mg/d micronized progesterone (m-P) for the first 12 d of each month, 211 women randomized to receive 50 μg/d transdermal estradiol (t-E2) plus 200 mg/d m-P for the first 12 d of each month, and 262 women randomized to receive placebo pills and patches. Primary outcomes included the Modified Mini-Mental State examination; four cognitive factors: verbal learning/memory, auditory attention/working memory, visual attention/executive function, and speeded language/mental flexibility; and a mood measure, the Profile of Mood States (POMS). MHT effects were analyzed using linear mixed-effects (LME) models, which make full use of all available data from each participant, including those with missing data. Data from those with and without full data were compared to assess for potential biases resulting from missing observations. For statistically significant results, we calculated effect sizes (ESs) to evaluate the magnitude of changes. On average, participants were 52.6 y old, and 1.4 y past their last menstrual period. By month 48, 169 (24.4%) and 158 (22.8%) of the 693 women who consented for ancillary KEEPS-Cog were lost to follow-up for cognitive assessment (3MS and cognitive factors) and mood evaluations (POMS), respectively. However, because LME models make full use all available data, including data from women with missing data, 95.5% of participants were included in the final analysis (n = 662 in cognitive analyses, and n = 661 in mood analyses). To be included in analyses, women must have provided baseline data, and data from at least one post-baseline visit. The mean length of follow-up was 2.85 y (standard deviation [SD] = 0.49) for cognitive outcomes and 2.76 (SD = 0.57) for mood outcomes. No treatment-related benefits were found on cognitive outcomes. For mood, model estimates indicated that women treated with o-CEE showed improvements in depression and anxiety symptoms over the 48 mo of treatment, compared to women on placebo. The model estimate for the depression subscale was −5.36 × 10−2 (95% CI, −8.27 × 10−2 to −2.44 × 10−2; ES = 0.49, p < 0.001) and for the anxiety subscale was −3.01 × 10−2 (95% CI, −5.09 × 10−2 to −9.34 × 10−3; ES = 0.26, p < 0.001). Mood outcomes for women randomized to t-E2 were similar to those for women on placebo. Importantly, the KEEPS-Cog results cannot be extrapolated to treatment longer than 4 y. Conclusions The KEEPS-Cog findings suggest that for recently postmenopausal women, MHT did not alter cognition as hypothesized. However, beneficial mood effects with small to medium ESs were noted with 4 y of o-CEE, but not with 4 y of t-E2. The generalizability of these findings is limited to recently postmenopausal women with low cardiovascular risk profiles.

    Salty taste perception affects salt intake, of which excess amounts is a major public health concern. Gene polymorphisms in salty taste receptors, zinc status and their interaction may affect salty taste perception. In this study, we examined the relationships among the α-epithelial sodium channel (αENaC) A663T genotype, zinc intake, and salty taste perception including salty taste acuity and preference in healthy young adults. The αENaC A663T genotype was determined by the PCR-restriction fragment length polymorphism in 207 adults. Zinc intake was examined by one 24-h recall and a two-day dietary record. Salty taste acuity and preference were determined by measuring the salty taste recognition threshold and the preferred salinity of beansprout soup, respectively. Men had significantly higher thresholds and preferences for salty taste than women did (p < 0.05). In women, the salty taste threshold was significantly lower in the highest tertile of available zinc intake than in the lowest tertile (12.2 mM and 17.6 mM, respectively, p = 0.02). Interestingly, a significant inverse association between available zinc intake and salty taste threshold was found only in women with αENaC AA homozygotes (β = −0.833, p = 0.02), and no such association was found in T663 allele carriers. The salty taste preference was not associated with the αENaC A663T genotype or available zinc intake in either sex. In conclusion, our data suggest that gene-nutrient interactions between the αENaC A663T genotype and available zinc intake play a role in determining the salty taste acuity in young women.

    Lutein is a carotenoid that varies in breast milk depending on maternal intake. Data are lacking with regard to the effect of dietary lutein supplementation on breast milk lutein concentration during lactation and subsequent plasma lutein concentration in breast-fed infants. This study was conducted to determine the impact of lutein supplementation in the breast milk and plasma of lactating women and in the plasma of breast-fed infants 2–3 mo postpartum. Lutein is the dominant carotenoid in the infant brain and the major carotenoid found in the retina of the eye. Eighty-nine lactating women 4–6 wk postpartum were randomly assigned to be administered either 0 mg/d of lutein (placebo), 6 mg/d of lutein (low-dose), or 12 mg/d of lutein (high-dose). The supplements were consumed for 6 wk while mothers followed their usual diets. Breast milk carotenoids were measured weekly by HPLC, and maternal plasma carotenoid concentrations were measured at the beginning and end of the study. Infant plasma carotenoid concentrations were assessed at the end of the study. No significant differences were found between dietary lutein + zeaxanthin intake and carotenoid concentrations in breast milk and plasma or body mass index at baseline. Total lutein + zeaxanthin concentrations were greater in the low- and high-dose–supplemented groups than in the placebo group in breast milk (140% and 250%, respectively; P < 0.0001), maternal plasma (170% and 250%, respectively; P < 0.0001), and infant plasma (180% and 330%, respectively; P < 0.05). Lutein supplementation did not affect other carotenoids in lactating women or their infants. Lactating women are highly responsive to lutein supplementation, which affects plasma lutein concentrations in the infant. This trial was registered at clinicaltrials.gov as NCT01747668.

  6. Attenuation of positive and negative affect in men and women at increased risk for hypertension: a function of endogenous barostimulation?

    PubMed

    Wilkinson, Daniel Z; France, Christopher R

    2009-01-01

    We hypothesized that activation of endogenous baroreflexes would be associated with reduced responsivity to affective stimuli and that this effect would be enhanced in individuals at risk for hypertension. Images from the International Affective Picture System were presented during systolic and diastolic phases of the cardiac cycle. Affective responsivity was measured using electromyographic activity, skin conductance, and ratings of arousal and valence. Compared to offspring of normotensives, individuals with a parental history of hypertension showed reduced responsivity to both positive and negative affective stimuli; however, responsivity did not differ as a function of cardiac cycle phase. Although these findings do not support a barostimulation mechanism of affective dampening, it is premature to discount the baroreflex inhibition hypothesis given the limited affective reactions elicited by visual stimuli presented in the laboratory.

    The hydrogen disproportionation reaction was investigated for three Nd-Fe-B-based alloys-Nd14.9Dy1.0Fe76.1B8.0, Nd15.2Dy1.0Fe74.8B8.3Zr0.7 and Nd15.4Dy1.0Fe73.3B8.3Zr2.0-using a modified vibrating-sample magnetometer. The addition of zirconium was found to substantially slow down the rate of the disproportionation reaction. A more surprising result, however, was the presence of a two-stage reaction for the Zr-free material, which prevents us from interpreting the disproportionation reaction in terms of the Johnson-Mehl-Avrami-Kolmogorov (JMAK) theory of phase transformations. Our isothermal experiments at 650°C resulted in very low values in the range 0.6-0.7 for the Avrami transformation constant. These low values also suggest that the standard JMAK model is inappropriate for describing the process of disproportionation in these alloys, and an extension to the JMAK theory that takes into account a critical radius for stable iron nuclei is required to explain these low values.

    Disproportionation in 3d compounds can give rise to an unconventional electron-hole Bose liquid with a very rich phase diagram, from a Bose metal, to a charge ordering insulator and an inhomogeneous Bose-superfluid. Optimal conditions for disproportionation driven high-T(c) superconductivity are shown to be realized only for several Jahn-Teller d(n) configurations that permit the formation of well defined local composite bosons. These are the high-spin d(4), low-spin d(7), and d(9) configurations given the octahedral crystal field, and the d(1), high-spin d(6) configurations given the tetrahedral crystal field. The disproportionation reaction has a peculiar 'anti-Jahn-Teller' character lifting the bare orbital degeneracy. Superconductivity in the d(4) and d(6) systems at variance with d(1), d(7), and d(9) systems implies unavoidable coexistence of the spin-triplet composite bosons and the magnetic lattice. We argue that unconventional high-T(c) superconductivity, observed in quasi-2d cuprates with tetragonally distorted CuO(6) octahedra and iron-based layered pnictides/chalcogenides with tetrahedrally coordinated Fe(2+) ions presents a key argument to support the fact that the disproportionation scenario is at work in these compounds.

  15. High progesterone levels in women with high ovarian response do not affect clinical outcomes: a retrospective cohort study

    PubMed Central

    2014-01-01

    Background The potentially detrimental role of progesterone during the follicular phase has been a matter of controversy for several years; however, few studies have analyzed the effects of combined raised estradiol and progesterone levels on pregnancy outcomes. The aim of the present study was to determine the influence of high progesterone levels on clinical outcomes in the context of high ovarian response. Methods We performed a retrospective cohort study that included 2850 women classified as high responders. The women were subdivided into six groups depending on their progesterone concentration on the day of human chorionic gonadotropin (hCG) administration: <0.5 ng/ml (1.81 ng/ml (>p90). Ovarian response was classified as high when > =20 oocytes were retrieved or when estradiol was > =3000 pg/ml. Clinical outcomes of each subgroup were analyzed. We also examined data from frozen-thawed embryo transfers. Results were analyzed with Student’s t- test to compare continuous variables and chi-squared test to compare proportions. A p-value of < =0.05 was considered statistically significant. Results The progesterone concentration increased with ovarian response, and elevated progesterone did not show a significant clinical impact on implantation rate and pregnancy rates. These data provide evidence that progesterone levels higher than 1.8 ng/ml do not have detrimental effect on oocyte quality or endometrial receptivity. Conclusions These data allow us to conclude that high progesterone levels correlate significantly with high estradiol levels and that in high responder women; progesterone levels do not show a significant clinical impact on results.

    Background Perinatal common mental disorders (PCMDs) are a major cause of disability among women and disproportionately affect lower income countries. Interventions to address PCMDs are urgently needed in these settings, and group-based and peer-led approaches are potential strategies to increase access to mental health interventions. Participatory womens health groups led by local women previously reduced postpartum psychological distress in eastern India. We assessed the effect of a similar intervention on postpartum psychological distress in rural Bangladesh. Method We conducted a secondary analysis of data from a cluster-randomised controlled trial with 18 clusters and an estimated population of 532,996. Nine clusters received an intervention comprising monthly meetings during which womens groups worked through a participatory learning and action cycle to develop strategies for improving womens and childrens health. There was one group for every 309 individuals in the population, 810 groups in total. Mothers in nine control clusters had access to usual perinatal care. Postpartum psychological distress was measured with the 20-item Self Reporting Questionnaire (SRQ-20) between six and 52 weeks after delivery, during the months of January to April, in 2010 and 2011. Results We analysed outcomes for 6275 mothers. Although the cluster mean SRQ-20 score was lower in the intervention arm (mean 5.2, standard deviation 1.8) compared to control (5.3, 1.2), the difference was not significant (? 1.44, 95% CI 0.28, 3.08). Conclusions Despite promising results in India, participatory womens groups focused on womens and childrens health had no significant effect on postpartum psychological distress in rural Bangladesh.

    Ecological momentary assessment was used to examine associations between negative affect, positive smoking outcome expectancies, and smoking urge during the first 7 days of a smoking quit attempt. Participants were 302 female smokers who enrolled in an individually tailored smoking cessation treatment study. Multilevel mediation analysis was used to examine the temporal relationship among: 1) the effects of negative affect and positive smoking outcome expectancies at one assessment point (e.g., time j) on smoking urge at the subsequent time point (e.g., time j + 1) in Model 1; and, 2) the effects of negative affect and smoking urge at time j on positive smoking outcome expectancies at time j + 1 in Model 2. The results from Model 1 showed a statistically significant effect of negative affect at time j on smoking urge at time j + 1, and this effect was mediated by positive smoking outcome expectancies at time j, both within- and between-participant. In Model 2, the within-participant indirect effect of negative affect at time j on positive smoking outcome expectancies at time j + 1 through smoking urge at time j was nonsignificant. However, a statistically significant indirect between-participant effect was found in Model 2. The findings support the hypothesis that urge and positive smoking outcome expectancies increase as a function of negative affect, and suggest a stronger effect of expectancies on urge as opposed to the effect of urge on expectancies.

    Hormones (progesterone and estradiol) change greatly during pregnancy; however, the mechanism of hormonal changes on gingival inflammation is still unclear. This study is to evaluate the effects of hormonal changes during pregnancy on gingival inflammation and interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in gingival crevicular fluid (GCF). 30 periodontally healthy pregnant women were evaluated in the first, second, and third trimesters. 20 periodontally healthy nonpregnant women were evaluated twice (once per subsequent month). Clinical parameters including probing pocket depth (PPD), bleeding index (BI), gingival index (GI), clinical attachment level (CAL), and plaque index (PLI) were recorded. GCF levels of IL-1β and TNF-α and serum levels of progesterone and estradiol were measured. From the data, despite low PLI, BI and GI increased significantly during pregnancy; however, no significant changes in PLI, CAL, IL-1β, or TNF-α GCF levels were observed. Although IL-1β, not TNF-α, was higher in pregnant group than in nonpregnant group, they showed no correlation with serum hormone levels during pregnancy. GI and BI showed significant positive correlation with serum hormone levels during pregnancy. This study suggests that sex hormone increase during pregnancy might have an effect on inflammatory status of gingiva, independent of IL-1β and TNF-α in GCF. PMID:27034591

    Fetal nutrition is thought to be an important determinant of later disease risk, although evidence from randomized-controlled trials in humans is lacking. We followed children born during a protein-energy supplementation trial to investigate to what extent this maternal supplement, which improved birth weight, influenced offspring body composition in adolescence. Subjects were 1270 Gambian children (659 boys, 611 girls) aged 11-17 y whose mothers had participated in the original cluster-randomized trial and had received the supplement during pregnancy (intervention) or postpartum (control). Basic anthropometry was measured using standard techniques and fatness was assessed by bioelectrical impedance analysis and population-specific prediction equations. For boys, mean body fat was 12.6% for both intervention and control groups. Mean trunk fat was 11.9% in the intervention group and 12.0% in the control. Intervention girls had a mean body fat of 19.5% and trunk fat of 15.2%; for control girls, it was 19.3 and 14.8%, respectively. BMI, body fat, trunk fat, fat mass index, and fat-free mass index did not differ for either sex when analyzed with generalized estimating equations adjusted for age, maternal height, maternal parity, location, season of birth, and menarche in females. Neither infant-attained size nor the onset of menarche were affected by maternal supplementation. These findings suggest that protein-energy supplements to pregnant women, compared with lactating women, do not affect offspring body composition during adolescence. PMID:19022974

    In an effort to address inconsistencies in the literature, we tested a cross-species estrogen withdrawal model of postpartum depression (PPD) with a series of rodent experiments and a prospective, naturalistic human study. All rats were ovariectomized prior to experimentation. The first rat experiment examined the effects of low- and high-dose estradiol administration and withdrawal on lateral-hypothalamic self-stimulation, a behavioral index of anhedonia, in experimental (n=7) and vehicle-only control animals (n=7). The second rat experiment examined the effects of high-dose estradiol withdrawal on activity and immobility during the forced swim test, an index of behavioral despair, in a separate group of experimental (n=8) and vehicle-only control animals (n=8). In the human study, women with (n=8) and without (n=12) a history of PPD completed mood ratings and collected saliva samples (to assess estradiol levels) daily during the third trimester of pregnancy through 10 days postpartum. The presence of PPD was assessed at one month postpartum. In the animal studies, rats in the estradiol withdrawal group demonstrated significantly greater immobility and less swimming than controls. Estradiol withdrawal resulted in reduced responding for electrical stimulation (multiple intensities) relative to estradiol administration. In the human study, there was no significant association between estradiol and negative affect among women with or without a history of PPD. However, there was a correlation between daily estradiol levels and negative affect in the women with incident PPD at one month postpartum. Despite important cross-species differences, both the rat and human studies provided evidence of the effects of estradiol on perinatal depressive symptoms. PMID:23770328

    Recent studies have indicated that omega-3 (n3) polyunsaturated fatty acids (PUFAs) decrease adipose tissue inflammation in rodents and in morbidly obese humans. We investigated whether a diet rich in n3 PUFAs from both marine and plant sources reduces adipose tissue and systemic inflammation in overweight to moderately obese adults. We conducted a randomized, single-blind, parallel-design, placebo-controlled feeding trial. Healthy men and women with a body mass index between 28 and 33 kg/m2 consumed a diet rich in n3 PUFAs (3.5% of energy intake; n = 11) from plant and marine sources or a control diet (0.5% of energy intake from n3 PUFAs; n = 13). These diets were consumed for 14 wk (ad libitum for 12 wk). All foods were provided for the entire study period. Subcutaneous abdominal adipose tissue and fasting plasma were collected after the first 2 wk with the control diet and again at the end of the 14-wk dietary period. The primary outcome of this ex post analysis was the adipose tissue gene expression of 13 key mediators of inflammation. Adipose tissue gene expression of inflammatory mediators did not differ between the 2 groups, after adjustment for weight change. Furthermore, none of the 5 plasma markers of systemic inflammation differed significantly as an effect of diet treatment. We conclude that a relatively high dose of n3 PUFAs from plant and marine sources did not significantly lower adipose tissue or systemic inflammation in overweight to moderately obese healthy men and women over 14 wk.

    Resistance training has been recommended for maintenance or improvement of the functional health of older adults, but its effect on acute cardiovascular responses remains unclear. Thus, the purpose of this study was to analyze the effect of 12 weeks of resistance training on post-exercise blood pressure (BP) in normotensive older women. Twenty-eight normotensive and physically inactive women (≥ 60 years) were randomly assigned to a training group (TG) or a control group (CG). The TG underwent a resistance training program (12 weeks, 8 exercises, 2 sets, 10-15 repetitions, 3 days/week), while the CG performed stretching exercises (12 weeks, 2 sets, 20 s each, 2 days/week). At baseline and after the intervention, participants were randomly submitted to two experimental sessions: a resistance exercise session (7 exercises, 2 sets, 10-15 repetitions) and a control session. BP was obtained pre- and post-sessions (90 min), through auscultation. Post-exercise hypotension was observed for systolic, diastolic, and mean BP in the TG (-6.1, -3.4, and -4.3 mmHg, respectively; P < 0.05) and in the CG (-4.1, -0.7, and -1.8 mmHg, respectively; P < 0.05). After the intervention period, the magnitude and pattern of this phenomenon for systolic, diastolic, and mean BP were similar between groups (TG -8.8, -4.1, and -5.7 mmHg, respectively; P < 0.05 vs CG -11.1, -5.8, and -7.6 mmHg, respectively; P < 0.05). These results indicate that a single session of resistance exercise promotes reduction in post-exercise BP and 12 weeks of resistance training program do not change the occurrence or magnitude of this hypotension.

    The reaction pathways and kinetics of C1 aldehydes, formaldehyde (HCHO) and formic acid (HCOOH=HOCHO), are studied at 400 degrees C in neat condition and in supercritical water over a wide range of water density, 0.1-0.6 g/cm3. Formaldehyde exhibits four reactions: (i) the self-disproportionation of formaldehyde generating methanol and formic acid, (ii) the cross-disproportionation between formaldehyde and formic acid generating methanol and carbon dioxide, (iii) the water-independent self-disproportionation of formaldehyde generating methanol and carbon monoxide, and (iv) the decarbonylation of formaldehyde generating hydrogen and carbon monoxide. The self- and cross-disproportionations overwhelm the water-independent self-disproportionation and the formaldehyde decarbonylation. The rate constants of the self- and cross-disproportionations are determined in the water density range of 0.1-0.6 g/cm3. The rate constant of the cross-disproportionation is 2-3 orders of magnitude larger than that of the self-disproportionation, which indicates that formic acid is a stronger reductant than formaldehyde. Combining the kinetic results with our former computational study on the equilibrium constants of the self- and cross-disproportionations, the reaction mechanisms of these disproportionations are discussed within the framework of transition-state theory. The reaction path for methanol production can be controlled by tuning the water density and reactant concentrations. The methanol yield of approximately 80% is achieved by mixing formaldehyde with formic acid in the ratio of 1:2 at the water density of 0.4 g/cm3. PMID:17388377

    Disproportionating enzyme from potato was crystallized and preliminarily analyzed using X-ray diffraction. Disproportionating enzyme (D-enzyme; EC 2.4.1.25) is a 59 kDa protein that belongs to the α-amylase family. D-enzyme catalyses intramolecular and intermolecular transglycosylation reactions of α-1,4 glucan. A crystal of the D-enzyme from potato was obtained by the hanging-drop vapour-diffusion method. Preliminary X-ray data showed that the crystal diffracts to 2.0 Å resolution and belongs to space group C222{sub 1}, with unit-cell parameters a = 69.7, b = 120.3, c = 174.2 Å.

    Transmission electron microscopy studies have been carried out on partially disproportionated NdFeB-type alloys. A new intermediate magnetic (NIM) phase has been identified. Moreover, the lamella structure which subsequently develops from the tetragonal NIM phase comprises a tetragonal NdFe-containing (IL) phase and {alpha}-Fe. The experimental data show strong evidence of a well-defined crystallographic relation between both the NIM and lamella phases and between the IL phase and {alpha}-Fe. These observations give insight into how crystallographic texture, and hence anisotropy, can be developed in NdFeB-type powders processed by the hydrogenation, disproportionation, desorption, and recombination route. {copyright} 2001 American Institute of Physics.

  7. The production of 34S-depleted sulfide during bacterial disproportionation of elemental sulfur

    Canfield, D. E.; Thamdrup, B.

    1994-01-01

    Bacteria that disproportionate elemental sulfur fractionate sulfur isotopes such that sulfate is enriched in sulfur-34 by 12.6 to 15.3 per mil and sulfide is depleted in sulfur-34 by 7.3 to 8.6 per mil. Through a repeated cycle of sulfide oxidation to S0 and subsequent disproportionation, these bacteria can deplete sedimentary sulfides in sulfur-34. A prediction, borne out by observation, is that more extensive sulfide oxidation will lead to sulfides that are more depleted in sulfur-34. Thus, the oxidative part of the sulfur cycle creates circumstances by which sulfides become more depleted in sulfur-34 than would be possible with sulfate-reducing bacteria alone.

    HIV disproportionately affects women, which propagates the disparities gap. This study was designed to (a) explore the personal, cognitive, and psychosocial factors of intimate partner violence (IPV) among women with HIV, (b) explore the perceptions of male perpetrators’ roles in contributing to violence, and (c) determine the implications for methodological and data source triangulation. A concurrent mixed methods study design was used including 30 African American male and female participants. Quantitative data were analyzed using descriptive statistics. Eleven themes were identified in the qualitative data from the female (n = 15) and 9 themes from the male (n = 15) participant interviews using Giorgi’s technique. Data sources and methodological approaches were triangulated with relative convergence in the results. Preliminary data generated from this study could inform gender-based feasibility research studies. These studies could focus on integrating findings from this study in HIV/IPV prevention interventions and provide clinical support for women. PMID:24503500

    A quasi in situ X-ray absorption study demonstrated that the disproportionation of hydrogen peroxide (H2O2) promoted by ceria nanorods was associated with a reversible Ce(3+)/Ce(4+) reaction and structural transformations in ceria. The direction of this reversible reaction was postulated to depend on the H2O2 concentration and the fraction of Ce(3+) species in ceria nanorods. PMID:26981885

    A new chemolithotrophic bacterial metabolism was discovered in anaerobic marine enrichment cultures. Cultures in defined medium with elemental sulfur (S0) and amorphous ferric hydroxide (FeOOH) as sole substrates showed intense formation of sulfate. Furthermore, precipitation of ferrous sulfide and pyrite was observed. The transformations were accompanied by growth of slightly curved, rod-shaped bacteria. The quantification of the products revealed that S0 was microbially disproportionated to sulfate and sulfide, as follows: 4S0 + 4H2O → SO42- + 3H2S + 2H+. Subsequent chemical reactions between the formed sulfide and the added FeOOH led to the observed precipitation of iron sulfides. Sulfate and iron sulfides were also produced when FeOOH was replaced by FeCO3. Further enrichment with manganese oxide, MnO2, instead of FeOOH yielded stable cultures which formed sulfate during concomitant reduction of MnO2 to Mn2+. Growth of small rod-shaped bacteria was observed. When incubated without MnO2, the culture did not grow but produced small amounts of SO42- and H2S at a ratio of 1:3, indicating again a disproportionation of S0. The observed microbial disproportionation of S0 only proceeds significantly in the presence of sulfide-scavenging agents such as iron and manganese compounds. The population density of bacteria capable of S0 disproportionation in the presence of FeOOH or MnO2 was high, > 104 cm-3 in coastal sediments. The metabolism offers an explanation for recent observations of anaerobic sulfide oxidation to sulfate in anoxic sediments. PMID:16348835

    A correct diagnosis of primary aldosteronism (PA) requires adrenal venous sampling (AVS) for the classification of subtypes (bilateral hyperplasia, BAH, or adenoma, APA). Since such testing is not easily practicable, appropriate markers for the definition of subtypes are desirable. We hypothesized that an aldosterone excess was associated with abnormalities in urinary proteome, specific for PA subtypes. The project work was divided into 3 phases: (1) screening/identification by proteomic analysis and further characterization by RT-PCR and immunohistochemistry of the candidate protein; (2) clinical validation by quantitative ELISA assay of 57 (33 M, 24 F) PA patients and 50 normotensive controls (21 M, 29 F); (3) analysis of adrenal tissue of 8 individuals who had undergone adrenalectomy for APA or other adrenal tumors. The proteomic analysis showed a different expression of Serpin B3 Inhibitor-SCCA1 (SB3) in APA and BAH patients. Urine SB3 concentrations in normotensive controls, quantified by ELISA assay and normalized by urinary creatinine, resulted much lower in males (6.72 ng SB3 per mg creatinine, C.I. 4.43-10.19) than in females (20.56 ng SB3 per mg creatinine, C.I. 12.43-33.99, p < 0.00001). SB3 concentrations were not significantly different in males affected by different PA subtypes (BAH, n = 19 and APA, n = 14) compared with normotensive subjects (n = 21). In contrast, in PA females, SB3 was significantly higher in APA (n = 13) than in BAH patients (n = 11) or in normotensive controls (n = 29) (P < 0.01 and <0.05, respectively). Neither messenger RNA nor SB3 protein were identified in tissue obtained from adrenal tumors and from the surrounding normal gland. In conclusion urine SB3 concentrations are physiologically much lower in males than in females. Hypertensive women, affected by APA, present urinary SB3 concentrations significantly higher than women affected by BAH. PMID:24503858

    It is widely accepted that cold exposure increases peripheral vascular resistance and arterial blood pressure (BP) and, hence, increases cardiovascular risk primarily in the elderly. However, there is a lack of concomitantly longitudinal recordings at personal level of environmental temperature (PET) and cardiophysiological variables together with skin temperatures (STs, the “interface-variable” between the body core and ambient temperature). To investigate the intra-individual temporal relationships between PET, STs and BP 60 healthy young women (52 completed the entire study) were prospectively studied in a winter/summer design for 26 h under real life conditions. The main hypothesis was tested whether distal ST (Tdist)mediates the effect of PET-changes on mean arterial BP (MAP). Diurnal profiles of cardiophysiological variables (including BP), STs and PET were ambulatory recorded. Daytime variations between 0930 and 2030 h were analyzed in detail by intra-individual longitudinal path analysis. Additionally, time segments before, during and after outdoor exposure were separately analyzed. In both seasons short-term variations in PET were positively associated with short-term changes in Tdist (not proximal ST, Tprox) and negatively with those in MAP. However, long-term seasonal differences in daytime mean levels were observed in STs but not in BP leading to non-significant inter-individual correlation between STs and BP. Additionally, higher individual body mass index (BMI) was significantly associated with lower daytime mean levels of Tprox and higher MAP suggesting Tprox as potential mediator variable for the association of BMI with MAP. In healthy young women the thermoregulatory and BP-regulatory systems are closely linked with respect to short-term, but not long-term changes in PET. One hypothetical explanation could serve recent findings that thermogenesis in brown adipose tissue is activated in a cool environment, which could be responsible for the counter-regulation of cold induced increase of BP in winter leading to no seasonal differences in MAP. Our findings suggest that the assessment of diurnal patterns of STs and PET, in addition to the conventional ambulatory BP monitoring, might improve individual cardiovascular risk prediction.

    Prenatal maternal stress (PNMS) can impact a variety of outcomes in the offspring throughout childhood and persisting into adulthood as shown in human and animal studies. Many of the effects of PNMS on offspring outcomes likely reflect the effects of epigenetic changes, such as DNA methylation, to the fetal genome. However, no animal or human research can determine the extent to which the effects of PNMS on DNA methylation in human offspring is the result of the objective severity of the stressor to the pregnant mother, or her negative appraisal of the stressor or her resulting degree of negative stress. We examined the genome-wide DNA methylation profile in T cells from 34 adolescents whose mothers had rated the 1998 Québec ice storm's consequences as positive or negative (that is, cognitive appraisal). The methylation levels of 2872 CGs differed significantly between adolescents in the positive and negative maternal cognitive appraisal groups. These CGs are affiliated with 1564 different genes and with 408 different biological pathways, which are prominently featured in immune function. Importantly, there was a significant overlap in the differentially methylated CGs or genes and biological pathways that are associated with cognitive appraisal and those associated with objective PNMS as we reported previously. Our study suggests that pregnant women's cognitive appraisals of an independent stressor may have widespread effects on DNA methylation across the entire genome of their unborn children, detectable during adolescence. Therefore, cognitive appraisals could be an important predictor variable to explore in PNMS research. PMID:25710121

    Animal studies in vivo indicate that leptin treatment in extremely leptin-sensitive ob/ob mice reduces body weight exclusively by reducing fat mass and that it increases muscle mass by downregulating myostatin expression. Data from human trials are limited. Therefore, we aimed at characterizing the effects of leptin administration on fat mass, lean body mass, and circulating regulators of muscle growth in hypoleptinemic and presumably leptin-sensitive human subjects. In an open-label, single-arm trial, seven lean, strenuously exercising, amenorrheic women with low leptin concentrations (≤5 ng/ml) were given recombinant methionyl human leptin (metreleptin; 0.08 mg·kg−1·day−1) for 10 wk. In a separate randomized, double-blind, placebo-controlled trial, seven women were given metreleptin (initial dose: 0.08 mg·kg−1·day−1 for 3 mo, increased thereafter to 0.12 mg·kg−1·day−1 if menstruation did not occur), and six were given placebo for 9 mo. Metreleptin significantly reduced total body fat by an average of 18.6% after 10 wk (P < 0.001) in the single-arm trial and by 19.5% after 9 mo (placebo subtracted; P for interaction = 0.025, P for metreleptin = 0.004) in the placebo-controlled trial. There were no significant changes in lean body mass (P ≥ 0.33) or in serum concentrations of myostatin (P ≥ 0.35), follistatin (P ≥ 0.30), and activin A (P ≥ 0.20) whether in the 10-wk trial or the 9-mo trial. We conclude that metreleptin administration in lean hypoleptinemic women reduces fat mass exclusively and does not affect lean body mass or the myostatin-follistatin-activin axis. PMID:21505147

    Engaging in nature-based activities is recognised as providing the basis for easily accessible, cost-effective interventions which can have other important physical and psychological health outcomes. The aim of the reported feasibility study was to explore the acceptability and potential psychological benefits of a simple ecotherapy-based intervention for individuals affected by cancer. A total of seven women from an existing breast cancer support group agreed to take part in the study by cultivating and customising a garden bowl for three months, maintaining a diary, and participating in a focus group at the end of the project. The analysis of the focus group data revealed four main themes that suggested that the women found engaging with the intervention to be therapeutic on a number of different levels: reflecting their cancer journey, a source of positivity, making meaning through memories, and a sense of control provided by engagement with the intervention. Engagement with the diary-writing element of the intervention, however, was not as widely endorsed by the group, as participants were even reluctant to make use of an online forum to share experiences of engaging with the intervention. Overall, the study suggests that the flexibility of level of engagement with an intervention is an important factor in developing acceptable interventions, and that the value of targeted recruitment to improve engagement with novel interventions is paramount.

    Universal prenatal daily iron-folic acid (IFA) and multiple micronutrient (MM) supplements are recommended to reduce the risk of low birth weight, maternal anemia, and iron deficiency (ID) during pregnancy, but the evidence of their effect on iron status among women with mild or no anemia is limited. The aim of this study was to describe the iron status [serum ferritin (SF), serum soluble transferrin receptor (sTfR), and body iron (BI)] before and after micronutrient supplementation during pregnancy. We examined 834 pregnant women with hemoglobin > 100 g/L at enrollment before 20 wk of gestation and with iron measurement data from a subset of a randomized, double-blind trial in China. Women were randomly assigned to take daily 400 ?g of folic acid (FA) (control), FA plus 30 mg of iron, or FA, iron, plus 13 additional MMs provided before 20 wk of gestation to delivery. Venous blood was collected in this subset during study enrollment (before 20 wk of gestation) and 28-32 wk of gestation. We found that, at 28-32 wk of gestation, compared with the FA group, both the IFA and MM groups had significantly lower prevalence of ID regardless of which indicator (SF, sTfR, or BI) was used for defining ID. The prevalence of ID at 28-32 wk of gestation for IFA, MM, and FA were 35.3%, 42.7%, and 59.6% by using low SF, 53.6%, 59.9%, and 69.9% by using high sTfR, and 34.5%, 41.2%, and 59.6% by using low BI, respectively. However, there was no difference in anemia prevalence (hemoglobin < 110 g/L) between FA and IFA or MM groups. We concluded that, compared with FA alone, prenatal IFA and MM supplements provided to women with no or mild anemia improved iron status later during pregnancy but did not affect perinatal anemia. This trial was registered at clinicaltrials.gov as NCT00137744. PMID:24744317

    Uterine fibroids (leiomyomas) are the most common benign pelvic tumors in women and are the major indication for hysterectomy. Fibroids are more common and more severe among African American women. Although this disease disproportionately affects the African American population, we understand little about what causes this disparity. Fibroids should be considered a public health issue, given the magnitude of the problem and the costs of health care for this disease. In this review, we examine the burden of disease from fibroids in the African American population and review the natural history, diagnosis, and treatment of uterine fibroids, with emphasis on how these can differ, depending on race. We also focus on the socioeconomic burden caused by the disease and describe the anticipated influence of new health care reforms and funding mechanisms for fibroid research. PMID:23942040

    Caring for offspring diagnosed with a chronic psychological disorder such as autism spectrum disorder (ASD) is used in research as a model of chronic stress. This chronic stress has been reported to have deleterious effects on caregivers' cognition, particularly in verbal declarative memory. Moreover, such cognitive decline may be mediated by testosterone (T) levels and negative affect, understood as depressive mood together with high anxiety and anger. This study aimed to compare declarative memory function in middle-aged women who were caregivers for individuals with ASD (n = 24; mean age = 45) and female controls (n = 22; mean age = 45), using a standardised memory test (Rey's Auditory Verbal Learning Test). It also sought to examine the role of care recipient characteristics, negative mood and T levels in memory impairments. ASD caregivers were highly sensitive to proactive interference and verbal forgetting. In addition, they had higher negative affect and T levels, both of which have been associated with poorer verbal memory performance. Moreover, the number of years of caregiving affected memory performance and negative affect, especially, in terms of anger feelings. On the other hand, T levels in caregivers had a curvilinear relationship with verbal memory performance; that is, increases in T were associated with improvements in verbal memory performance up to a certain point, but subsequently, memory performance decreased with increasing T. Chronic stress may produce disturbances in mood and hormonal levels, which in turn might increase the likelihood of developing declarative memory impairments although caregivers do not show a generalised decline in memory. These findings should be taken into account for understanding the impact of cognitive impairments on the ability to provide optimal caregiving. PMID:25915711

    Stereotyped pulsed calls were attributed to 11 killer whales (Orcinus orca) with and without synchronous bubble streams in three datasets collected from two facilities from 1993 to 2012. Calls with and without synchronous bubble streams and divergent overlapping high frequency components ("biphonic" vs "monophonic") were compared. Subjects produced bubbles significantly more often when calls had divergent high frequency components. However, acoustic features in one biphonic call shared by five subjects provided little evidence for an acoustic effect of synchronous bubble flow. Disproportionate bubbling supported other evidence that biphonic calls form a distinct category, but suggested a function in short-range communication. PMID:25698045

    Background The excess burden of obesity among black women is well-documented. However, the behavioral weight loss intervention literature often does not report results by ethnic group or gender. Purpose The purpose of this article is to conduct a systematic review of all behavioral weight loss intervention trials published between 1990 and 2010 that included and reported results separately for black women. Methods The criteria for inclusion included: 1) participants age ≥18 years; 2) a behavioral weight loss intervention; 3) weight as an outcome variable; 4) inclusion of black women; and 5) weight loss results reported separately by ethnicity and gender. Results The literature search identified 25 studies that met inclusion criteria. Our findings suggest more intensive randomized behavioral weight loss trials with medically at-risk populations yield better results. Conclusions Well-designed and more intensive multi-site trials with medically at-risk populations currently offer the most promising results for black women. Still, black women lose less weight than other subgroups in behavioral weight loss interventions. It is now critical to expand on individual-level approaches and incorporate the biological, social, and environmental factors that influence obesity. This will help enable the adoption of healthier behaviors for this group of women disproportionately affected by obesity. PMID:22074195

    Background. We explored healthcare provider perspectives and practices regarding safer conception counseling for HIV-affected clients. Methods. We conducted semistructured interviews with 38 providers (medical and clinical officers, nurses, peer counselors, and village health workers) delivering care to HIV-infected clients across 5 healthcare centres in Mbarara District, Uganda. Interview transcripts were analyzed using content analysis. Results. Of 38 providers, 76% were women with median age 34 years (range 24-57). First, we discuss providers' reproductive counseling practices. Emergent themes include that providers (1) assess reproductive goals of HIV-infected female clients frequently, but infrequently for male clients; (2) offer counseling focused on "family planning" and maternal and child health; (3) empathize with the importance of having children for HIV-affected clients; and (4) describe opportunities to counsel HIV-serodiscordant couples. Second, we discuss provider-level challenges that impede safer conception counseling. Emergent themes included the following: (1) providers struggle to translate reproductive rights language into individualized risk reduction given concerns about maternal health and HIV transmission and (2) providers lack safer conception training and support needed to provide counseling. Discussion. Tailored guidelines and training are required for providers to implement safer conception counseling. Such support must respond to provider experiences with adverse HIV-related maternal and child outcomes and a national emphasis on pregnancy prevention. PMID:27051664

    The human Val⁶⁶Met single nucleotide polymorphism in the brain-derived neurotrophic factor (BDNF) gene impacts BDNF signaling at the cellular level. At the neural-systems level, it is associated with differences in prefrontal cortex (PFC) and hippocampal function during performance of cognitive and affective tasks. Because the impact of this variant on basal prefrontal and hippocampal activity is not known but may be relevant to understanding the function of this gene in health and disease, we studied 94 healthy individuals with H₂ ¹⁵O PET to assess regional cerebral blood flow (rCBF) during rest and tested for between-genotype differences. Because BDNF and gonadal steroid hormones conjointly influence neuronal growth, survival, and plasticity in hippocampus and PFC, we also tested for sex × genotype interactions. Finally, in light of the known impact of BDNF on plasticity and dendritic arborization, we complimented direct rCBF comparisons with connectivity analyses to determine how activity in hippocampal and prefrontal regions showing between-genotype group differences covaries with rCBF in other nodes throughout the brain in a genotype- or sex-dependent manner. Compared with Val homozygotes, Met carriers had higher rCBF in prefrontal (BA25 extending into BA10) and hippocampal/parahippocampal regions. Moreover, there were significant sex × genotype interactions in regions (including frontal, parahippocampal, and lateral temporal cortex) in which Val homozygotes showed higher rCBF in females than males, but Met carriers showed the opposite relationship. Functional connectivity analysis demonstrated that correlations of BA25, hippocampus, and parahippocampus with frontal and temporal networks were positive for Val homozygotes and negative for Met carriers. In addition, sex × genotype analysis of functional connectivity revealed that genotype affected directionality of the inter-regional correlations differentially in men versus women. Our data indicate that BDNF allelic variation and sex interactively affect basal prefrontal and hippocampal function. PMID:22593075

    Background: Noncommunicable diseases (NCDs) are an emerging public health problem, accounting for 80% of deaths in low and middle-income countries leading to a global epidemic. The increasing burden of NCDs is affecting poor and disadvantaged women population disproportionately, contributing to widening health gaps between and within countries. Globalization and urbanization have led to lifestyle changes among urban poor, which need to be understood, as the urban areas are undergoing rapid transitions. Objectives: To know prevalence and pattern of behavioral risk factors for NCDs in working and nonworking women of urban slums to initiate steps for preventive interventions. Materials and Methods: This was community based cross-sectional study conducted among women of urban slums in the age-group of 30-45 years on a voluntary basis. Data were collected by the house-to-house survey using predesigned and pretested proforma World Health Organization-Stepwise Approach to Chronic Disease Risk Factor Surveillance (WHO-STEPS 1 and 2 questionnaires). Descriptive statistics and Chi-square test were used for analysis. Results: Majority, 49% women were in the age-group of 30-35 years, with 60.5% belonging to Class IV socio-economic status. Stress was present in 38% working women as compared to 17% nonworking women (?2 = 22.12, df = 1, P < 0.0001, HS). Nonworking women (25%) were less aware about common NCDs compared to (48%) working women (?2 = 22.82, df = 1, P < 0.0001, HS). It was also found that 11% women were newly diagnosed with hypertension. Conclusion: Most of the women were not aware of the risk factors leading to NCDs. Screening and IEC activities need to be strengthened and hence that diagnosis and preventive measures can be implemented at an early stage of life. PMID:25317001

    A novel chemolithotrophic metabolism based on a mixed arsenic-sulfur species has been discovered for the anaerobic deltaproteobacterium, strain MLMS-1, a haloalkaliphile isolated from Mono Lake, California, U.S. Strain MLMS-1 is the first reported obligate arsenate-respiring chemoautotroph which grows by coupling arsenate reduction to arsenite with the oxidation of sulfide to sulfate. In that pathway the formation of a mixed arsenic-sulfur species was reported. That species was assumed to be monothioarsenite ([H2As(III)S(-II)O2](-)), formed as an intermediate by abiotic reaction of arsenite with sulfide. We now report that this species is monothioarsenate ([HAs(V)S(-II)O3](2-)) as revealed by X-ray absorption spectroscopy. Monothioarsenate forms by abiotic reaction of arsenite with zerovalent sulfur. Monothioarsenate is kinetically stable under a wide range of pH and redox conditions. However, it was metabolized rapidly by strain MLMS-1 when incubated with arsenate. Incubations using monothioarsenate confirmed that strain MLMS-1 was able to grow (μ = 0.017 h(-1)) on this substrate via a disproportionation reaction by oxidizing the thio-group-sulfur (S(-II)) to zerovalent sulfur or sulfate while concurrently reducing the central arsenic atom (As(V)) to arsenite. Monothioarsenate disproportionation could be widespread in nature beyond the already studied arsenic and sulfide rich hot springs and soda lakes where it was discovered. PMID:25941832

    During the cycling of Li-O₂ batteries the discharge process gives rise to dynamically evolving agglomerates composed of lithium-oxygen nanostructures; however, little is known about their composition. In this paper, we present results for a Li-O₂ battery based on an activated carbon cathode that indicate interfacial effects can suppress disproportionation of a LiO₂ component in the discharge product. High-intensity X-ray diffraction and transmission electron microscopy measurements are first used to show that there is a LiO₂ component along with Li₂O₂ in the discharge product. The stability of the discharge product was then probed by investigating the dependence of the charge potential and Raman intensity of the superoxide peak with time. The results indicate that the LiO₂ component can be stable for possibly up to days when an electrolyte is left on the surface of the discharged cathode. Density functional calculations on amorphous LiO₂ reveal that the disproportionation process will be slower at an electrolyte/LiO₂ interface compared to a vacuum/LiO₂ interface. The combined experimental and theoretical results provide new insight into how interfacial effects can stabilize LiO₂ and suggest that these interfacial effects may play an important role in the charge and discharge chemistries of a Li-O₂ battery.

    Adsorption reactions are important for understanding the distribution of ions between aqueous and solid phases; they govern solution concentrations, bioavailability, and mobility of ions in the environment. Iron disulfide is a sorbent of cadmium in reduced systems but sorption on sulfides is not well understood. The purpose of this research is to determine the surface structures and products of cadmium sorbed on amorphous FeS{sub 2}. Raman spectroscopy, x-ray diffraction, electron microscopy, and scanning tunneling microscopy were used to study the disulfide surface. The FeS{sub 2} undergoes surface reconstruction and disproportionation during cadmium sorption, which leads to discrete zones of elemental sulfur, cadmium sulfide, and iron hydroxide. Therefore, simple surface complexation is not the predominant mechanism of sorption. Disproportionation may provide a mechanism for the surface to reorganize and for isolated crystalline cadmium sulfide domains to develop. Cadmium surface precipitates are very stable and their formation may be a significant means of attenuating this hazardous element. Thus, it appears that FeS{sub 2} may be an important sorbent of cadmium in natural environments.

The stability of the discharge product was then probed by investigating the dependence of the charge potential and Raman intensity of the superoxide peak with time. The results indicate that the LiO2 component can be stable for possibly up to days when an electrolyte is left on the surface of the discharged cathode. Density functional calculations on amorphous LiO2 reveal that the disproportionation process will be slower at an electrolyte/LiO2 interface compared to a vacuum/LiO2 interface. The combined experimental and theoretical results provide new insight into how interfacial effects can stabilize LiO2 and suggest that these interfacial effects may play an important role in the charge and discharge chemistries of a Li-O2 battery.

    A novel chemolithotrophic metabolism based on a mixed arsenic−sulfur species has been discovered for the anaerobic deltaproteobacterium, strain MLMS-1, a haloalkaliphile isolated from Mono Lake, California, U.S. Strain MLMS‑1 is the first reported obligate arsenate-respiring chemoautotroph which grows by coupling arsenate reduction to arsenite with the oxidation of sulfide to sulfate. In that pathway the formation of a mixed arsenic−sulfur species was reported. That species was assumed to be monothioarsenite ([H2AsIIIS−IIO2] −), formed as an intermediate by abiotic reaction of arsenite with sulfide. We now report that this species is monothioarsenate ([HAsVS−IIO3] 2−) as revealed by X-ray absorption spectroscopy. Monothioarsenate forms by abiotic reaction of arsenite with zerovalent sulfur. Monothioarsenate is kinetically stable under a wide range of pH and redox conditions. However, it was metabolized rapidly by strain MLMS-1 when incubated with arsenate. Incubations using monothioarsenate confirmed that strain MLMS-1 was able to grow (μ = 0.017 h−1 ) on this substrate via a disproportionation reaction by oxidizing the thio-group-sulfur (S−II) to zerovalent sulfur or sulfate while concurrently reducing the central arsenic atom (AsV) to arsenite. Monothioarsenate disproportionation could be widespread in nature beyond the already studied arsenic and sulfide rich hot springs and soda lakes where it was discovered.

    We investigated whether and to what extent children who are racial/ethnic minorities are disproportionately represented in early intervention and/or early childhood special education (EC/ECSE). We did so by analyzing a large sample of 48-month-olds (N=7,950) participating in the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B), a nationally representative dataset of children born in the U.S. in 2001. Multivariate logistic regression analyses indicate that boys (OR=1.66), children born at very low birthweight (OR=3.98) or with congenital anomalies (OR=2.17), and children engaging in externalizing problem behaviors (OR=1.10) are more likely to be represented in EI/ECSE. Children from low SES households (OR=.48), those displaying greater numeracy or receptive language knowledge (ORs=.96 and .76, respectively), and children being raised in households where a language other than English is primarily spoken (OR=.39) are less likely to be represented in EI/ECSE. Statistical control for these and an extensive set of additional factors related to cognitive and behavioral functioning indicated that 48-month-old children who are Black (OR=.24) or Asian (OR=.32) are disproportionately under-represented in EI/ECSE in the U.S. PMID:24683265

    There is broad consensus that the diversity of functional traits within species assemblages drives several ecological processes. It is also widely recognized that rare species are the first to become extinct following human-induced disturbances. Surprisingly, however, the functional importance of rare species is still poorly understood, particularly in tropical species-rich assemblages where the majority of species are rare, and the rate of species extinction can be high. Here, we investigated the consequences of local and regional extinctions on the functional structure of species assemblages. We used three extensive datasets (stream fish from the Brazilian Amazon, rainforest trees from French Guiana, and birds from the Australian Wet Tropics) and built an integrative measure of species rarity versus commonness, combining local abundance, geographical range, and habitat breadth. Using different scenarios of species loss, we found a disproportionate impact of rare species extinction for the three groups, with significant reductions in levels of functional richness, specialization, and originality of assemblages, which may severely undermine the integrity of ecological processes. The whole breadth of functional abilities within species assemblages, which is disproportionately supported by rare species, is certainly critical in maintaining ecosystems particularly under the ongoing rapid environmental transitions.

  1. Few colonies of the host Bombus terrestris disproportionately affect the genetic diversity of its parasite, Crithidia bombi.

    Sex and recombination have long been considered as necessary means for hosts to keep up with and resist to their faster reproducing parasites. On the other hand, comparatively little attention has been paid to potential benefits of recombination for the parasites. Using as model organisms the bumblebee Bombus terrestris and its genetically highly variable trypanosomatid parasite Crithidia bombi we analysed the infection dynamics as well as the relative frequency of parasite recombinants over time, in colonies that were either immune-challenged with heat-killed bacteria or sham-inoculated. In addition, we used infective cells from a given colony to infect workers from other, untreated colonies, to investigate whether recombinant parasite strains may have a competitive advantage over the parental strains to infect the surrounding host population. We show that in our experimental setup the host immune status does not influence the proportion of recombinant parasite cells in the infection. Neither do recombinant parasite strains have an advantage over the parental ones at infecting workers unrelated to the host colony the infection originally came from. However, we found that the prevalence of recombinants was highly variable among colonies, with one particular colony producing significantly more recombinant strains than others. As the successful infection of daughter queens--the only individuals surviving the winter to the next year--is proportional to the number of circulating parasite strains in the colony, we suggest that such "super-producing" colonies may be responsible for most of the infections happening in the next year.

  3. Trends in Medicare disproportionate share (DSH) distribution in US hospitals: 1996-2003.

    2006-01-01

    Implemented in 1986, Medicare's disproportionate share (DSH) adjustment is intended to recognize hospitals' additional resource investment in caring for low-income patients. This project analyzed changes in the DSH percentage between 1996 and 2003 and examined the association between selected hospital characteristics and such changes. Results obtained revealed some interesting findings. First, minimal changes in DSH percentage occurred during the period 1996-1999 with a hike in that ratio in 2000-2001. However, even with the absence of any legislative or executive changes to the DSH threshold or formula during 2002 and 2003, significant increases occurred during 2001-2003 (11 percent increase between 2001 and 2003). Such an increase may be caused by the nation's economic situation during that timeframe (i.e., more people depending on public programs for coverage). PMID:19175241

    We examined traditional environmental justice populations and other groups whose exposure to contaminants is often disproportionately high. Risk assessment methods may not identify these populations, particularly if they are spatially dispersed. We suggest using a National Health and Nutrition Examination Survey approach to oversample minority communities and develop methods for assessing exposure at different distances from pollution sources; publishing arithmetic and geometric means and full distributions for minority populations; and paying particular attention to high-end exposures. Means may sufficiently characterize populations as a whole but are inadequate in identifying vulnerable groups and subgroups. The number of individuals above the 95th percentile of any distribution may be small and unrepresentative, but these outliers are the ones who need to be protected. PMID:21551384

    Children receive greater exposures to environmental pollutants present in air, food, and water because they inhale or ingest more air, food, or water on a body-weight basis than adults do. Communities of color are disproportionately exposed in hazardous wastes, dioxin, and air pollution. Existing data demonstrate that children of color are the subgroup of the population most exposed to certain pollutants, including lead, air pollution, and pesticides. Government standards do not take into account children`s differential exposures or the cumulative nature of these exposures. Federal regulations fail to protect the most highly exposed and most sensitive subgroups of the population. More often than not this group is children of color. 13 refs.

    Many diet-related chronic diseases take a disproportionate toll among members of racial minorities. Research shows the prevalence of diabetes, hypertension, cancer, and heart disease is higher among various ethnic groups compared with whites. The Guidelines and the Food Guide Pyramid, however, promote the use of multiple servings of meats and dairy products each day and do not encourage replacing these foods with vegetables, legumes, fruits, and grains. The Dietary Guidelines for Americans encourage a 30% caloric reduction in fat intake and make no provision for further reductions for those who wish to minimize health risks. Abundant evidence has shown that regular exercise combined with diets lower in fat and richer in plant products than is encouraged by the Dietary Guidelines for Americans are associated with reduced risk of these chronic conditions. While ineffective Dietary Guidelines potentially put all Americans at unnecessary risk, this is particularly true for those groups hardest hit by chronic disease. PMID:10333669

One contributing factor may be the obstacles such communities face to full participation in making policy decisions about environmental health. This study described and analyzed the characteristics that contributed to communities' capacity to participate in making environmental decisions and suggested steps public agencies could take to achieve more meaningful participation. By strengthening community capacity, advancing authentic participation, and building democratic power, it might be possible to alter current patterns of health inequities. Strengthening participation by working with communities to develop the capacities needed to be effective in such processes is a key role for local, state, and national environmental agencies.

    The mineralogical constitution of the Earth's mantle dictates the geophysical and geochemical properties of this region. Previous models of a perovskite-dominant lower mantle have been built on the assumption that the entire lower mantle down to the top of the D″ layer contains ferromagnesian silicate [(Mg,Fe)SiO3] with nominally 10 mole percent Fe. On the basis of experiments in laser-heated diamond anvil cells, at pressures of 95 to 101 gigapascals and temperatures of 2200 to 2400 kelvin, we found that such perovskite is unstable; it loses its Fe and disproportionates to a nearly Fe-free MgSiO3 perovskite phase and an Fe-rich phase with a hexagonal structure. This observation has implications for enigmatic seismic features beyond ~2000 kilometers depth and suggests that the lower mantle may contain previously unidentified major phases. PMID:24855264

    Background African-Americans are more likely be seen by physicians with less clinical training or treated at hospitals with deficient times to acute reperfusion therapies. Less is known about differences in health outcomes. This paper compares risk-adjusted mortality following Acute Myocardial Infarction (AMI) between U.S. hospitals with high and low fractions of elderly black AMI patients. Methods and Results A prospective cohort study was performed for fee-for-service Medicare patients hospitalized for AMI during 1997–2001 (N = 1,136,736). Hospitals (N =4289) were classified into approximate deciles depending on the extent to which the hospital served the African-American population. The lowest category (12.5 percent of AMI patients) included hospitals without any African-American AMI admissions during 1997–2001. Decile 10 (10 percent of AMI patients) included hospitals with the highest fraction of black AMI patients (33.6 percent). The main outcome measures were 90-day and 30-day mortality following AMI. Patients admitted to hospitals disproportionately serving African-Americans experienced no greater level of morbidities or severity of the infarction. Yet hospitals in Decile 10 experienced risk-adjusted 90-day mortality rate of 23.7 percent (95% CI: 23.2–24.2) compared to 20.1 percent (95% CI: 19.7–20.4) in Decile 1 hospitals. Differences in outcomes between hospitals were not explained by income, hospital ownership status, hospital volume, Census region, urban status, or hospital surgical treatment intensity. Conclusions Risk-adjusted mortality following AMI is significantly higher in U.S. hospitals that disproportionately serve African-Americans. A reduction in overall mortality at these hospitals could reduce dramatically black-white disparities in health care outcomes. PMID:16246963

    Worldwide, transgender women who engage in sex work have a disproportionate risk for HIV compared with natal male and female sex workers. We reviewed recent epidemiological research on HIV in transgender women and show that transgender women sex workers (TSW) face unique structural, interpersonal, and individual vulnerabilities that contribute to risk for HIV. Only six studies of evidence-based prevention interventions were identified, none of which focused exclusively on TSW. We developed a deterministic model based on findings related to HIV risks and interventions. The model examines HIV prevention approaches in TSW in two settings (Lima, Peru and San Francisco, CA, USA) to identify which interventions would probably achieve the UN goal of 50% reduction in HIV incidence in 10 years. A combination of interventions that achieves small changes in behaviour and low coverage of biomedical interventions was promising in both settings, suggesting that the expansion of prevention services in TSW would be highly effective. However, this expansion needs appropriate sustainable interventions to tackle the upstream drivers of HIV risk and successfully reach this population. Case studies of six countries show context-specific issues that should inform development and implementation of key interventions across heterogeneous settings. We summarise the evidence and knowledge gaps that affect the HIV epidemic in TSW, and propose a research agenda to improve HIV services and policies for this population. PMID:25059941

    Growing evidence suggests intimate partner violence (IPV) and substance misuse are co-occurring problems that disproportionately affect low income urban women seeking care in emergency departments (EDs) and represent leading causes of injuries that result in ED visits. This paper examines temporal bi-directional associations between different types of drug and alcohol use and different types of IPV in a longitudinal study of a representative sample of 241 low income, urban women receiving emergency care from an ED in the Bronx, New York. After adjusting and matching for socio-demographics and potentially confounding multi-level risk and protective covariates, women who reported using heroin in the prior six months at Wave 1 were twice as likely as non-heroin using women to indicate any physical, injurious or sexual IPV at subsequent waves and were 2.7 times more likely to indicate experiencing an injury from IPV at subsequent waves. Crack or cocaine use in the past 6 months at Wave 1 was associated with an increased likelihood of injurious IPV and severe verbal abuse at subsequent waves. Findings also suggested that sexual IPV was significantly associated with subsequent use of crack or cocaine. The multiple bidirectional associations found linking these problems underscore the need for conducting routine screening for IPV and substance misuse among women in low income, urban EDs, and for improving linkages to services that will ultimately reduce the risk of morbidity, disability, and mortality related to these co-occurring problems.

  16. Jobs: women's double burden.

    PubMed

    1995-01-01

    Whereas international conventions and national laws provide equal opportunities for women in employment, the reality of women's lives keeps a disproportionate number of women unemployed, underemployed, and living in poverty. The UN itself, which officially is working toward equity among its employees, has a staff composed of just 32.6% women, and women comprise only 10.5% of the top end of the hierarchy. In areas where women's labor force participation has increased dramatically, women typically earn 30-40% less than men doing the same job or else their employment is limited to "traditional female" service positions. The fact that women and girls have received an inadequate education makes it extremely difficult to break the barriers of discrimination in developing countries. The empowerment of women will break the education barrier, and, when that falls, many other barriers will follow suit. Efforts are already underway to break structural barriers caused by economic and social policies. For example, a more flexible pattern of work has been proposed which will include the voluntary assumption of flexible hours, job-sharing, and part-time work. The concept of work is also being broadened to include the important human services that women traditionally provide on a volunteer basis. This will lead to a valuation of women's contribution to society which can be added to calculations of gross domestic product. Women also need protection as they attempt to eke out a living in the informal sector which has been the traditional avenue for women to earn money. This sector is not protected by law and is subject to extortion by officials and by male competitors. A variety of measures is under consideration to increase the protection of informal sector workers. Women also need protection in the conventional work place, especially as they enter fields traditionally reserved for men. These questions are important even in the context of global unemployment because these issues must be addressed or their resolution to women's disadvantage will gain the mantle of tradition.

    Introduction The results of studies examining the influence of subclinical hypothyroidism (SCH) and levothyroxine (L-T4) replacement therapy on bone have generated considerable interest but also controversy. The present research aims to evaluate the effects of L-T4 treatment on different skeletal sites in women. Material and methods A group of 45 premenopausal (mean age: 43.62 ±6.65 years) and 180 postmenopausal (mean age: 59.51 ±7.90 years) women with SCH who were undergoing L-T4 replacement therapy for at least 6 months were compared to 58 pre- and 180 postmenopausal women with SCH (untreated) matched for age. The mean doses of L-T4 were 90.88 ±42.59 µg/day in the premenopausal women and 86.35 ±34.11 µg/day in the postmenopausal women. Bone measurements were obtained using quantitative bone ultrasound (QUS) for the phalanx, dual-energy X-ray absorptiometry (DXA) for the lumbar spine and hip, and peripheral quantitative computed tomography (pQCT) for the non-dominant distal forearm. Results No differences were observed between patients and untreated controls in these bone measurements except in the bone mineral density (BMD) of the spine (p = 0.0214) in postmenopausal women, which was greater in treated women than in untreated controls. Conclusions Our results indicate that adequate metabolic control through replacement treatment with L-T4 in pre- and postmenopausal women does not affect bone mass. PMID:26528344

    At present, it is difficult to determine whether glycemic index (GI) is an important tool in the prevention of lifestyle diseases, and long-term studies investigating GI with diets matched in macronutrient composition, fiber content, energy content, and energy density are still scarce. We investigated the effects of 2 high-carbohydrate (55%) diets with low GI (LGI; 79) or high GI (HGI; 103) on postprandial blood profile, subjective appetite sensations, energy expenditure (EE), substrate oxidation rates, and ad libitum energy intake (EI) from a corresponding test meal (LGI or HGI) after consuming the diets ad libitum for 10 wk. Two groups of a total of 29 healthy, overweight women (age: 30.5 ± 6.6 y; BMI: 27.6 ± 1.5 kg/m(2)) participated in the 10-wk intervention and a subsequent 4-h meal test. The breakfast test meals differed in GI but were equal in total energy, macronutrient composition, fiber content, and energy density. The LGI meal resulted in lower plasma glucose, serum insulin, and plasma glucagon-like peptide (GLP)-1 and higher plasma glucose-dependent insulinotropic polypeptide concentrations than the HGI meal (P ≤ 0.05). Ratings of fullness were slightly higher and the desire to eat something fatty was lower after the test meal in the LGI group (P < 0.05). Postprandial plasma GLP-2, plasma glucagon, serum leptin, plasma ghrelin, EE, substrate oxidation rates, and ad libitum EI at lunch did not differ between groups. In conclusion, postprandial glycemia, insulinemia, and subjective appetite ratings after a test meal were better after 10-wk ad libitum intake of a LGI compared to a HGI diet. EE and substrate oxidation rates were, however, not affected. These findings give some support to recommendations to consume a LGI diet. PMID:21775528

    Breast cancer affects thousands each year in the United States, and disproportionately affects certain subgroups. For example, the incidence of breast cancer in South Carolina is lower in African American compared with European American women by approximately 12% to 15%, but their mortality rate is twice as high as in European American women. The purpose of the study was to assess factors associated with breast cancer mortality between African American and European American women. Participants (n=314) in South Carolina's Breast and Cervical Cancer Early Detection Program (SCBCCEDP), which provides breast cancer screening and treatment services, during the years 1996-2004 were included in the study. Data, including tumor characteristics, delay intervals, and race, were examined using the chi(2) test and the Wilcoxon rank-sum test. Cox regression modeling was used to assess the relationship between delay intervals and other factors. No racial differences were found in age at diagnosis, tumor characteristics, or delay intervals. Time delay intervals did not explain differences and mortality rates by race. Survival, however, was affected by prognostic factors as well as by a significant interaction between hormone-receptor status and race. Despite the excellent record of the SCBCCEDP in screening and diagnostic or treatment referrals, the racial disparities in breast cancer mortality continue to exist in South Carolina. These findings highlight the need for future research into the etiology of racial differences, and their impact on breast cancer survival. PMID:18835941

  9. Bacterial Disproportionation of Elemental Sulfur in Marine Sediments Amplified by a Seafloor Fuel Cell

    Bacteria known to disproportionate elemental sulfur to sulfate and sulfide and to grow only in the presence of a sulfide scavenger have been enriched electrochemically in marine sediments. During a 7-month experiment designed to demonstrate sustained electrical energy harvesting by a seafloor fuel cell (Tender et al. 2002), a graphite anode embedded in sediment within Yaquina Bay, OR, developed a biofilm showing a 60% enrichment in δ-Proteobacteria belonging to the genera Desulfobulus/Desulfocapsa. Cytophagales showed a secondary enrichment in 36.7% of 16S rDNA sequences. These two groups of microorganisms made up 23.5% and 8.8%, respectively, of clones derived from graphite scrapings of a control cell with zero current. Sediment porewater profiles show millimolar increases in sulfate and iron concentrations, but also sulfide depletion approaching the active anode. Electron microprobe analyses reveal accumulations of sulfur and iron between the graphite surface of the anode and the overcoating biofilm with a Fe/S ratio below one. Extractions of iron mineral phases also indicate a small decrease in crystalline iron oxide near the anode. These chemical changes are consistent with four interactive processes. (1) Sulfide is oxidized to elemental sulfur directly at the anode. (2) The elemental sulfur promotes the microbial production of sulfate and FeS + FeS2. (3) Iron sulfide apparently dissolves to re-supply sulfide that is consumed by the anode. (4) Released Fe+2 accumulates and with organic ligands may catalyze the reduction and dissolution of crystalline iron oxide (Luther et al. 1992). Thus, we conclude the anodic half-cell reaction of the marine fuel cell provides a novel experimental approach for in situ enrichment of bacteria that disproportionate elemental sulfur while highlighting a biogeochemical cycle usually obscured by competing processes.

    The crystal and magnetic structures of charge-disproportionated Ca2FeMnO6 were analyzed by neutron powder diffraction. Ca2FeMnO6 is a layered double perovskite oxide with a two-dimensional arrangement of Mn(4+) and unusual high valence Fe(4+) at room temperature. When cooled, the compound shows charge disproportionation followed by magnetic transition. Around 200 K, the Fe(4+) shows the charge disproportionation to Fe(3+) and Fe(5+), which are ordered in a checkerboard pattern in the two-dimensional FeO6 octahedral layers. The magnetic transition occurs at 95 K, which is much lower than the charge disproportionation temperature. The magnetic structure is commensurate but noncollinear, and the antiferromagnetic coupling of Fe(3+) and Fe(5+) spins in the FeO6 octahedral layers gives the ferrimagnetic moments. The unique magnetic structure is described as a result of two-dimensional localization of the ligand holes with effective spins. PMID:26018730

    Like all women, women living with and at risk of acquiring HIV have the right to determine the number and timing of their pregnancies and to safely achieve their reproductive intentions. Yet, many women in Asia affected by HIV lack access to family planning services and experience disproportionately high rates of unintended pregnancy and abortion. Programs that have succeeded in promoting condom use and providing HIV prevention and treatment services in this region have largely missed the opportunity to address the contraceptive needs of the key populations they serve. The importance of better linkages between family planning and HIV policies and programs is now widely recognized by global health policymakers and donors. However, to date, most of the efforts to improve these linkages have been conducted in Africa. Greater attention is needed to the developing, implementing, and evaluating of integrated family planning/HIV approaches that are tailored to the political, cultural, and public health context in Asia. In this paper, we describe the use of and need for family planning among key populations affected by HIV in Asia, discuss the challenges to effectively addressing of these needs, and offer recommendations for strengthening the linkages between family planning and HIV policies and programs in the region.

  19. Effect of particle adsorption rates on the disproportionation process in pickering stabilised bubbles

    2014-05-01

    The degree of shrinkage of particle stabilised bubbles of various sizes, in a polydisperse bubble dispersion, has been investigated in the light of the finite adsorption times for the particles and the disproportionation kinetics of the bubbles. For the case where the system contains an abundance of particles we find a threshold radius, above which bubbles are stabilised without any significant reduction in their size. Bubbles with an initial radius below this threshold on the other hand undergo a large degree of shrinkage prior to stabilisation. As the ratio of the available particles to the bubbles is reduced, it is shown that the final bubble size, for the larger bubbles in the distribution, becomes increasingly governed by the number of particles, rather than their adsorption time per se. For systems with "adsorption controlled" shrinkage ratio, the final bubble distribution is found to be wider than the initial one, while for a "particle number controlled" case it is actually narrower. Starting from a unimodal bubble size distribution, we predict that at intermediate times, prior to the full stabilisation of all bubbles, the distribution breaks up into a bimodal one. However, the effect is transient and a unimodal final bubble size distribution is recovered, when all the bubbles are stabilised by the particles.

    Several examples of metallic electron-doped polycyclic aromatic hydrocarbons (PAHs) molecular crystals have recently been experimentally proposed. Some of them have superconducting components, but most other details are still unknown beginning with structure and the nature of metallicity. We carried out ab initio density functional calculations for La-Phenanthrene (La-PA), here meant to represent a generic case of three-electron doping, to investigate structure and properties of a conceptually simple case. To our surprise we found first of all that the lowest energy state is not metallic but band insulating, with a disproportionation of two inequivalent PA molecular ions and a low P1 symmetry, questioning the common assumption that three electrons will automatically metallize a PAH crystal. Our best metallic structure is metastable and slightly higher in energy, and retains equivalent PA ions and a higher P21 symmetry—the same generally claimed for metallic PAHs. We show that a “dimerizing” periodic distortion opens very effectively a gap in place of a symmetry related degeneracy of all P21 structures near the Fermi level, foreshadowing a possible role of that special intermolecular phonon in superconductivity of metallic PAHs. A Hubbard-Fröhlich model describing that situation is formulated for future studies.

  1. Disproportionate Share Hospital Payment Reductions May Threaten Financial Stability of Safety-Net Hospitals

    Safety-net hospitals rely on Disproportionate Share Hospital (DSH) payments to help cover uncompensated care costs and underpayments by Medicaid (known as Medicaid shortfalls). The Affordable Care Act (ACA) anticipates that insurance expansions will increase safety-net hospitals’ revenues, and reduces DSH payments accordingly. We examined the impact of the ACA’s Medicaid DSH reductions on California public hospitals’ financial stability by estimating how total DSH costs (uncompensated care costs and Medicaid shortfalls) will change as a result of insurance expansions and the offsetting DSH reductions. Decreases in uncompensated care costs due to the ACA insurance expansion may not match the ACA’s DSH reductions because of the high number of residually uninsured patients, low Medicaid reimbursement, and medical cost inflation. Taking these three factors into account, we estimate that California public hospitals’ total DSH costs will increase from $2.044 billion in 2010 to $2.363 billion in 2019, with unmet DSH costs of $1.381 billion to $1.537 billion.

    In this paper we report on a kinetics study of the discharge process and its relationship to the charge overpotential in a Li-O{sub 2} cell for large surface area cathode material. The kinetics study reveals evidence for a first-order disproportionation reaction during discharge from an oxygen-rich Li{sub 2}O{sub 2} component with superoxide-like character to a Li{sub 2}O{sub 2} component. The oxygen-rich superoxide-like component has a much smaller potential during charge (3.2-3.5 V) than the Li{sub 2}O{sub 2} component (similar to 4.2 V). The formation of the superoxide-like component is likely due to the porosity of the activated carbon used in the Li-O{sub 2} cell cathode that provides a good environment for growth during discharge. The discharge product containing these two components is characterized by toroids, which are assemblies of nanoparticles. The morphologic growth and decomposition process of the toroids during the reversible discharge/charge process was observed by scanning electron microscopy and is consistent with the presence of the two components in the discharge product. The results of this study provide new insight into how growth conditions control the nature of discharge product, which can be used to achieve improved performance in Li-O{sub 2} cell.

  3. Use of historical logging patterns to identify disproportionately logged ecosystems within temperate rainforests of southeastern Alaska.

    The forests of southeastern Alaska remain largely intact and contain a substantial proportion of Earth's remaining old-growth temperate rainforest. Nonetheless, industrial-scale logging has occurred since the 1950s within a relatively narrow range of forest types that has never been quantified at a regional scale. We analyzed historical patterns of logging from 1954 through 2004 and compared the relative rates of change among forest types, landform associations, and biogeographic provinces. We found a consistent pattern of disproportionate logging at multiple scales, including large-tree stands and landscapes with contiguous productive old-growth forests. The highest rates of change were among landform associations and biogeographic provinces that originally contained the largest concentrations of productive old growth (i.e., timber volume >46.6 m³/ha). Although only 11.9% of productive old-growth forests have been logged region wide, large-tree stands have been reduced by at least 28.1%, karst forests by 37%, and landscapes with the highest volume of contiguous old growth by 66.5%. Within some island biogeographic provinces, loss of rare forest types may place local viability of species dependent on old growth at risk of extirpation. Examination of historical patterns of change among ecological forest types can facilitate planning for conservation of biodiversity and sustainable use of forest resources. PMID:23866037

  4. Hemoptysis in patients of celiac disease with disproportionately severe anemia: tip of the iceberg?

    2013-01-01

    Idiopathic Pulmonary Hemosiderosis (IPH) is characterized by the triad of iron deficiency anemia, pulmonary infiltrates and haemoptysis with no recognizable cause. Since the first description of its association with Celiac Disease (CD) by Lane and Hamilton in 1971, only a few isolated cases have been reported in literature. Although it has been considered an uncommon association of two disease entities, recent reports indicate that prevalence of celiac disease is as high as one percent. Further, individually both celiac disease and IPH are known to present as refractory anemia only. We are reporting a young adult with Lane Hamilton Syndrome, who realized that he was having significant gastrointestinal complaints only when they disappeared on gluten free diet (GFD). This case report reiterates the fact that celiac disease should be considered in all patients of IPH because of the therapeutic implications. Further on review of literature, we believe that covert hemoptysis may be responsible for disproportionately severe anemia in patients of celiac disease. Thus, prevalence of this association may be more than currently believed. Further research in this regard may improve our understanding of pathogenesis of celiac disease. PMID:23514358

    We have studied pressure-induced chemical reactions in carbon monoxide using both a diamond anvil cell and a modified large volume press. Our spectroscopic data reveal that carbon monoxide disproportionates into molecular CO{sub 2} and a solid lactone-type polymer; photochemically above 3.2 GPa, thermochemically above 5 GPa at 300 K, or at 3 GPa and {approx}2000 K as achieved by laser heating. The solid product can be recovered at ambient conditions with a high degree of conversion, measured to be up to 95% of the original CO. Its fundamental chemical structure includes {beta}-lactone and conjugated C=C, which can be considered a severely modified polymeric carbon suboxide with open ladders and smaller five-membered rings. The polymer is metastable at ambient conditions, spontaneously liberating CO{sub 2} gases exothermically. We find that the recovered polymer has a high energy density, 1-8 kJ/g, and is very combustible. We estimate the density of recovered CO polymer to be at least 1.65 g/cm{sup 3}.

    The indirect medical education (IME) and disproportionate share hospital (DSH) adjustments to Medicare's prospective payment rates for inpatient services are generally intended to compensate hospitals for patient care costs related to teaching activities and care of low income populations. These adjustments were originally established based on the statistical relationships between IME and DSH and hospital costs. Due to a variety of policy considerations, the legislated levels of these adjustments may have deviated over time from these “empirically justified levels,” or simply, “empirical levels.” In this paper, we estimate the empirical levels of IME and DSH using 2006 hospital data and 2009 Medicare final payment rules. Our analyses suggest that the empirical level for IME would be much smaller than under current law— about one-third to one-half. Our analyses also support the DSH adjustment prescribed by the Affordable Care Act of 2010 (ACA)—about one-quarter of the pre-ACA level. For IME, the estimates imply an increase in costs of 1.88% for each 10% increase in teaching intensity. For DSH, the estimates imply that costs would rise by 0.52% for each 10% increase in the low-income patient share for large urban hospitals. PMID:22340777

    Transition-metal-arene complexes such as bis(benzene)chromium Cr(η(6)-C(6)H(6))(2) are historically important to d-orbital bonding theory and have modern importance in organic synthesis, catalysis and organic spintronics. In investigations of f-block chemistry, however, arenes are invariably used as solvents rather than ligands. Here, we show that simple uranium complexes UX(3) (X = aryloxide, amide) spontaneously disproportionate, transferring an electron and X-ligand, allowing the resulting UX(2) to bind and reduce arenes, forming inverse sandwich molecules [X(2)U(µ-η(6):η(6)-arene)UX(2)] and a UX(4) by-product. Calculations and kinetic studies suggest a 'cooperative small-molecule activation' mechanism involving spontaneous arene reduction as an X-ligand is transferred. These mild reaction conditions allow functionalized arenes such as arylsilanes to be incorporated. The bulky UX(3) are also inert to reagents such as boranes that would react with the traditional harsh reaction conditions, allowing the development of a new in situ arene C-H bond functionalization methodology converting C-H to C-B bonds.

    The kinetics of toluene disproportionation has been studied over both unmodified and Si-Mg modified ZSM-5 catalysts using an integral reactor and taking into account the reversibility of the reaction. It has been found that xylene dealkylation is the major secondary reaction, whereas toluene dealkylation can be considered negligible. For the unmodified ZSM-5, heterogeneous models based in the alkyl-transfer mechanism allowed the experimental results to be fit better than first and second pseudohomogeneous models, the best concordance being obtained when toluene adsorption is assumed as the rate-limiting step. The corresponding kinetic equation has been further applied to the modified zeolite (SiMg/ZSM-5), leading to the development of a kinetic model which includes the effect of the toluene and p-xylene intracrystalline diffusion rate and the presence of nonselective acid sites on the external zeolite surface. This model describes adequately the selective formation of p-xylene over modified ZSM-5, reproducing the experimental product distribution with an average relative error of 2.8%.

    Sodium-ion batteries utilize various electrode materials derived from lithium batteries. However, the different characteristics inherent in sodium may cause unexpected cell reactions and battery performance. Thus, identifying the reactive discrepancy between sodiation and lithiation is essential for fundamental understanding and practical engineering of battery materials. Here we reveal a heterogeneous sodiation mechanism of iron fluoride (FeF2) nanoparticle electrodes by combining in situ/ex situ microscopy and spectroscopy techniques. In contrast to direct one-step conversion reaction with lithium, the sodiation of FeF2 proceeds via a regular conversion on the surface and a disproportionation reaction in the core, generating a composite structure of 1-4 nm ultrafine Fe nanocrystallites (further fused into conductive frameworks) mixed with an unexpected Na3FeF6 phase and a NaF phase in the shell. These findings demonstrate a core-shell reaction mode of the sodiation process and shed light on the mechanistic understanding extended to generic electrode materials for both Li- and Na-ion batteries.

    Atomistic simulation techniques are used to examine the defect chemistry of perovskite-structured NdCoO(3), a material whose electrochemical properties make it attractive for use in heterogeneous oxidation catalysis, as well as in gas sensors and mixed ionic/electronic conductors. In practice, dopants are added to NdCoO(3) to obtain the desired properties, such as high electrical conductivity and rapid gas adsorption/desorption; thus, a wide range of dopants substituted on both Nd and Co sites are examined. Charge compensation for aliovalent dopants is predicted to occur via formation of oxide ion vacancies; these are understood to be key sites with respect to catalytic and sensor activity. Low activation energies calculated for oxide ion migration are consistent with high oxygen mobilities measured experimentally. Sr and Ca, which occupy Nd sites in the lattice, are found to be the most soluble of the alkaline earth metals, in agreement with experiment. These two dopant ions also have the weakest binding energies for dopant-vacancy cluster formation. Mechanisms of electronic defect formation, critical to the overall transport properties of the material, are also considered. The results suggest that disproportionation of the Co ion to form small polaron species is the most favorable intrinsic defect process. In doped compounds, formation of electronic holes via uptake of oxygen at vacant sites is found to be a low energy process. PMID:16539474

  13. Hormone replacement therapy affects iron status more than endometrial bleeding in older US women: A role for estrogen in iron homeostasis?

    High iron levels in women of post-reproductive age may be related to their increased risk of chronic disease as they become older, but the causes of this rise in iron in late life is unclear. Recently estrogen has been implicated in non-human models of iron homeostasis. Studying iron in women who take hormone replacement therapy (HRT) may provide insight into the relationship between iron status and hormonal status in older women. This study examines the association between HRT and iron status in women aged 50+ who took part in the 1999-2000 National Health and Nutrition Examination Survey (NHANES). Data were analyzed using multiple imputation, which corrects for missing data, and complex survey regression, which adjusts for NHANES sampling. Current HRT use was associated with lower ferritin (β=-34.13, p=0.0002), controlling for potential breakthrough bleeding with a hysterectomy variable. HRT was associated with lower iron stores in women of post-reproductive in the absence of uterine blood loss, indicating potential homeostatic hormonal control of iron status. This research demonstrates the utility of studying clinical hormonal therapy to advance new understandings about the basic biology of iron homeostasis in women. PMID:27105697

    Low-income women and women of color are disproportionately affected by unintended pregnancy. Lack of knowledge of abortion laws and services is one of several factors likely to hinder access to services, though little research has documented knowledge in this population. Survey with convenience sample of 1,262 women attending primary care or full-scope Ob/Gyn clinics serving low-income populations in three large cities and multivariable analyses with four knowledge outcomes. Among all participants, 53% were first-generation immigrants, 25% identified the correct gestational age limit, 41% identified state parental consent laws, 67% knew partner consent is not required, and 55% knew where to obtain abortion services. In multivariable analysis, first-generation immigrants and primarily Spanish speakers were significantly less likely than higher-generation or primarily English speakers to display correct knowledge. Design and evaluation of strategies to improve knowledge about abortion, particularly among migrant women and non-primary English speakers, is needed. PMID:25488893

    South Africa has among the highest rates of HIV infection in the world, with women disproportionately affected. Alcohol-serving venues, where alcohol use and sexual risk often intersect, play an important role in HIV risk. Previous studies indicate alcohol use and gender inequity as drivers of this epidemic, yet these factors have largely been examined using person-level predictors. We sought to advance upon this literature by examining venue-level predictors, namely men's gender attitudes, alcohol, and sex behavior, to predict women's risks for HIV. We recruited a cohort of 554 women from 12 alcohol venues (6 primarily Black African, and 6 primarily Coloured [i.e., mixed race] venues) in Cape Town, who were followed for 1 year across four time points. In each of these venues, men's (N = 2216) attitudes, alcohol use, and sexual behaviors were also assessed. Men's attitudes and behaviors at the venue level were modeled using multilevel modeling to predict women's unprotected sex over time. We stratified analyses by venue race. As predicted, venue-level characteristics were significantly associated with women's unprotected sex. Stratified results varied between Black and Coloured venues. Among Black venues where men reported drinking alcohol more frequently, and among Coloured venues where men reported meeting sex partners more frequently, women reported more unprotected sex. This study adds to the growing literature on venues, context, and HIV risk. The results demonstrate that men's behavior at alcohol drinking venues relate to women's risks for HIV. This novel finding suggests a need for social-structural interventions that target both men and women to reduce women's risks. PMID:26768432

    It is not known whether folate metabolism is altered during pregnancy to support increased DNA and RNA biosynthesis. By using a state-of-the-art LC tandem mass spectrometry technique, the aim of this study was to investigate differences in RBC folate forms between pregnant and nonpregnant women and between nonpregnant women consuming different concentrations of supplemental folic acid. Forms of folate in RBCs were used to explore potential shifts in folate metabolism during early erythropoiesis. Total RBC folate and folate forms [tetrahydrofolate; 5-methyltetrahydrofolate (5-methyl-THF); 4α-hydroxy-5-methyl-tetrahydrofolate (an oxidation product of 5-methyl-THF); 5-formyl-tetrahydrofolate; and 5,10-methenyl-tetrahydrofolate] were measured in 4 groups of women (n = 26): pregnant women (PW) (30–36 wk of gestation) consuming 1 mg/d of folic acid, and nonpregnant women consuming 0 mg/d (NPW-0), 1 mg/d (NPW-1), and 5 mg/d (NPW-5) folic acid. The mean ± SD RBC folate concentration of the NPW-0 group (890 ± 530 nmol/L) was lower than the NPW-1 (1660 ± 350 nmol/L) and NPW-5 (1980 ± 570 nmol/L) groups as assessed by microbiologic assay (n = 26, P < 0.0022). No difference was found between the NPW-1 and NPW-5 groups. We detected 5-methyl-THF [limit of detection (LOD) = 0.06 nmol/L] in all groups and tetrahydrofolate (LOD = 0.2 nmol/L) in most women regardless of methylenetetrahydrofolate reductase genotype. Most women consuming folic acid supplements had detectable concentrations of 5,10-methenyl-tetrahydrofolate (LOD = 0.31 nmol/L). However, there was no difference in the relative distribution of 5-methyl-THF (83–84%), sum of non-methyl folates (0.6–3%), or individual non-methyl folate forms in RBCs across groups. We conclude that although folic acid supplementation in nonpregnant women increases RBC total folate and the concentration of individual folate forms, it does not alter the relative distribution of folate forms. Similarly, distribution of RBC folate forms did not differ between pregnant and nonpregnant women. This trial was registered at clinicaltrials.gov as NCT01741077. PMID:24991041

  19. Disproportionation pathways of aqueous hyponitrite radicals (HN2O2(*)/N2O2(*-)).

    2008-09-11

    Pulse radiolysis and flash photolysis are used to generate the hyponitrite radicals (HN2O2(*)/N2O2(*-)) by one-electron oxidation of the hyponitrite in aqueous solution. Although the radical decay conforms to simple second-order kinetics, its mechanism is complex, comprising a short chain of NO release-consumption steps. In the first, rate-determining step, two N2O2(*-) radicals disproportionate with the rate constant 2k = (8.2 +/- 0.5) x 10(7) M(-1) s(-1) (at zero ionic strength) effectively in a redox reaction regenerating N2O2(2-) and releasing two NO. This occurs either by electron transfer or, more likely, through radical recombination-dissociation. Each NO so-produced rapidly adds to another N2O2(*-), yielding the N3O3(-) ion, which slowly decomposes at 300 s(-1) to the final N2O + NO2(-) products. The N2O2(*-) radical protonates with pKa = 5.6 +/- 0.3. The neutral HN2O2(*) radical decays by an analogous mechanism but much more rapidly with the apparent second-order rate constant 2k = (1.1 +/- 0.1) x 10(9) M(-1) s(-1). The N2O2(*-) radical shows surprisingly low reactivity toward O2 and O2(*-), with the corresponding rate constants below 1 x 10(6) and 5 x 10(7) M(-1) s(-1). The previously reported rapid dissociation of N2O2(*-) into N2O and O(*-) does not occur. The thermochemistry of HN2O2(*)/N2O2(*-) is discussed in the context of these new kinetic and mechanistic results. PMID:18707066

    2015-01-01

    Insectivorous birds have been recognized as disproportionately sensitive to land-use intensification and habitat loss, with those species feeding primarily on the ground exhibiting some of the most dramatic declines. Altered litter inputs and availability of epigeic arthropods have been suggested to underlie reduced abundances and shrinking distributions but direct evidence is lacking. I used a patch-scale removal experiment in southern Australia to evaluate whether ground-feeding insectivores are especially vulnerable to altered litter-fall. Building on work demonstrating the importance of mistletoe litter to nutrient dynamics, litter was reduced by removing mistletoe (Loranthaceae) from one set of eucalypt woodlands, responses of birds three years after mistletoe removal compared with otherwise similar control woodlands containing mistletoe. Despite not feeding on mistletoes directly, insectivores exhibited the greatest response to mistletoe removal. Among woodland residents, ground-foraging insectivores showed the most dramatic response; treatment woodlands losing an average of 37.4% of their pre-treatment species richness. Once these 19 species of ground-foraging insectivores were excluded, remaining woodland species showed no significant effect of mistletoe removal. This response reflects greater initial losses in treatment woodlands during the study (which coincided with a severe drought) and double the number of species returning to control woodlands (where mistletoe numbers and litter were not manipulated) post-drought. These findings support the productivity-based explanation of declining insectivores, suggesting diminished litter-fall reduced habitat quality for these birds via decreased availability of their preferred prey. In addition to altered prey availability, interactions between litter-fall and epigeic arthropods exemplify the importance of below-ground / above-ground linkages driving ecosystem function.

  1. Production of electronic grade lunar silicon by disproportionation of silicon difluoride

    1993-01-01

    Waldron has proposed to extract lunar silicon by sodium reduction of sodium fluorosilicate derived from reacting sodium fluoride with lunar silicon tetrafluoride. Silicon tetrafluoride is obtained by the action of hydrofluoric acid on lunar silicates. While these reactions are well understood, the resulting lunar silicon is not likely to meet electronic specifications of 5 nines purity. Dale and Margrave have shown that silicon difluoride can be obtained by the action of silicon tetrafluoride on elemental silicon at elevated temperatures (1100-1200 C) and low pressures (1-2 torr). The resulting silicon difluoride will then spontaneously disproportionate into hyperpure silicon and silicon tetrafluoride in vacuum at approximately 400 C. On its own merits, silicon difluoride polymerizes into a tough waxy solid in the temperature range from liquid nitrogen to about 100 C. It is the silicon analog of teflon. Silicon difluoride ignites in moist air but is stable under lunar surface conditions and may prove to be a valuable industrial material that is largely lunar derived for lunar surface applications. The most effective driver for lunar industrialization may be the prospects for industrial space solar power systems in orbit or on the moon that are built with lunar materials. Such systems would require large quantities of electronic grade silicon or compound semiconductors for photovoltaics and electronic controls. Since silicon is the most abundant semimetal in the silicate portion of any solar system rock (approximately 20 wt percent), lunar silicon production is bound to be an important process in such a solar power project. The lunar silicon extraction process is discussed.

    A lack of appropriate proxies has traditionally hampered our ability to distinguish riverine organic carbon (OC) sources at the landscape scale. However, the dissection of C4 grasslands by C3-enriched riparian vegetation, and the distinct carbon stable isotope signature (δ(13)C) of these two photosynthetic pathways, provides a unique setting to assess the relative contribution of riparian and more distant sources to riverine C pools. Here, we compared δ(13)C signatures of bulk sub-basin vegetation (δ(13)CVEG) with those of riverine OC pools for a wide range of sites within two contrasting river basins in Madagascar. Although C3-derived carbon dominated in the eastern Rianala catchment, consistent with the dominant vegetation, we found that in the C4-dominated Betsiboka basin, riverine OC is disproportionately sourced from the C3-enriched riparian fringe, irrespective of climatic season, even though δ(13)CVEG estimates suggest as much as 96% of vegetation cover in some Betsiboka sub-basins may be accounted for by C4 biomass. For example, δ(13)C values for river bed OC were on average 6.9 ± 2.7‰ depleted in (13)C compared to paired estimates of δ(13)CVEG. The disconnection of the wider C4-dominated basin is considered the primary driver of the under-representation of C4-derived C within riverine OC pools in the Betsiboka basin, although combustion of grassland biomass by fire is likely a subsidiary constraint on the quantity of terrestrial organic matter available for export to these streams and rivers. Our findings carry implications for the use of sedimentary δ(13)C signatures as proxies for past forest-grassland distribution and climate, as the C4 component may be considerably underestimated due to its disconnection from riverine OC pools.

    Men and women with hyperandrogenemia have a more proatherogenic plasma lipid profile [e.g., greater triglyceride (TG) and total and low-density lipoprotein-cholesterol and lower high-density lipoprotein-cholesterol concentrations] than healthy premenopausal women. Furthermore, castration of male rats markedly reduces testosterone availability below normal and decreases plasma TG concentration, and testosterone replacement reverses this effect. Testosterone is, therefore, thought to be an important regulator of plasma lipid homeostasis. However, little is known about the effect of testosterone on plasma TG concentration and kinetics. Furthermore, testosterone is a potent skeletal muscle protein anabolic agent in men, but its effect on muscle protein turnover in women is unknown. We measured plasma lipid concentrations, hepatic very low density lipoprotein (VLDL)-TG and VLDL-apolipoprotein B-100 secretion rates, and the muscle protein fractional synthesis rate in 10 obese women before and after trandermal testosterone (1.25 g of 1% AndroGel daily) treatment for 3 wk. Serum total and free testosterone concentrations increased (P < 0.05) by approximately sevenfold in response to testosterone treatment, reaching concentrations that are comparable to those in women with hyperandrogenemia, but lower than the normal range for eugonadal men. Except for a small (∼10%) decrease in plasma high-density lipoprotein particle and cholesterol concentrations (P < 0.04), testosterone therapy had no effect on plasma lipid concentrations, lipoprotein particle sizes, and hepatic VLDL-TG and VLDL-apolipoprotein B-100 secretion rates (all P > 0.05); the muscle protein fractional synthesis rate, however, increased by ∼45% (P < 0.001). We conclude that testosterone is a potent skeletal muscle protein anabolic agent, but not an important regulator of plasma lipid homeostasis in obese women. PMID:22252942

    Background: Intimate partner violence (IPV) and risky sexual behaviors are serious and overlapping public health problems that disproportionately affect drug-involved women. Despite the fact that drug-using women experience extensive IPV, to date, no studies have investigated the association of IPV and risky sexual behaviors among drug-using women in Iran. Methods: Drug-using women (N =120) were recruited from a rehabilitation center in Tehran from March to October, 2009. The Revised Conflict Tactics Scale (CTS2), a standardized questionnaire, was used to collect data regarding violence. We used t-test and logistic regression models to explore the relationship between IPV domains and specific sexual risk behavior outcomes using SPSS 21. Results: The means (sd) for CTS2 domains were as follows: negotiation 4.29 (1.55), psychological violence 2.55 (1.51), sexual violence 0.37 (1.00), physical abuse 1.17 (1.49), injury 2.18 (1.97), and the mean total score was 1.69 (0.96). We found significantly higher injury scores, but lower sexual abuse scores among women with sexually-transmitted infection (STI) compared to women without STI (p-values 0.030 and <0.0001, respectively). In addition, we found that psychological abuse was positively associated with STI (p-value 0.03) and increased condom use (p = 0.010), possibly mediated through an increased likelihood of having multiple partners. Conclusion: The findings revealed that in Iran drug-involved women experience high rates of IPV and that IPV is associated with increased risky sexual behavior. Implication: Preventive interventions for violence that are integrated within drug treatment programs, as well as harm reduction programs are highly recommended. PMID:26034727

    GeO disproportionation into GeO{sub 2} and Ge is studied through x-ray photoelectron spectroscopy. Direct evidence for the reaction 2GeO {yields} GeO{sub 2} + Ge after annealing in ultra-high vacuum is presented. Activation energy for GeO disproportionation is found to be about 0.7 {+-} 0.2 eV through kinetic and thermodynamic calculations. A kinetic model of GeO disproportionation is established by considering oxygen transfer in the GeO network. The relationship between GeO disproportionation and GeO desorption induced by GeO{sub 2}/Ge interfacial reaction is discussed, and the apparent contradiction between GeO desorption via interfacial redox reaction and GeO disproportionation into Ge and GeO{sub 2} is explained by considering the oxygen vacancy.

    African American women are disproportionately affected by HIV/AIDS compared with other ethnicities, accounting for two-thirds (67%) of all women diagnosed with HIV. Despite their increased risk of HIV infection, few studies have been conducted to understand culture-specific factors leading to their vulnerability. Given the central role of religious organizations in African American communities, this study explored whether and to what extent religiosity plays a role in stigma toward HIV/AIDS. Results of hierarchical regression showed that after controlling for key factors, religiosity was a significant factor predicting the level of religious stigma. Those with high religiosity displayed significantly higher stigma, associating HIV/AIDS with a curse or punishment from God. Verbatim responses to an open-ended question also revealed seemingly ingrained prejudice against HIV/AIDS from a religious perspective. The findings point to the important role of faith-based organizations (FBOs) in addressing HIV/AIDS issues within African American communities. PMID:20574877

    Five studies tested the common assumption that women prefer nonconformist men as romantic partners, whereas men prefer conformist women. Studies 1 and 2 showed that both men and women preferred nonconformist romantic partners, but women overestimated the extent to which men prefer conformist partners. In Study 3, participants ostensibly in a small-group interaction showed preferences for nonconformist opposite-sex targets, a pattern that was particularly evident when men evaluated women. Dating success was greater the more nonconformist the sample was (Study 4), and perceptions of nonconformity in an ex-partner were associated with greater love and attraction toward that partner (Study 5). On the minority of occasions in which effects were moderated by gender, it was in the reverse direction to the traditional wisdom: Conformity was more associated with dating success among men. The studies contradict the notion that men disproportionately prefer conformist women. PMID:25805768

    HIV-infected infants and young children are at high risk of serious illness and death. Morbidity and mortality can be greatly reduced through early infant diagnosis (EID) of HIV and timely initiation of antiretroviral therapy (ART). Despite global efforts to scale-up of EID and infant ART, uptake of these services in resource poor, high HIV burden countries remain low. We conducted a qualitative study of 59 HIV-infected women to identify and explore barriers women face in accessing HIV testing and care for their infants. To capture different perspectives, we included mothers whose infants were known positive (n=9) or known negative (n=14), mothers of infants with unknown HIV status (n=13), and pregnant HIV-infected women (n=20). Five important themes emerged: lack of knowledge regarding EID and infant ART, the perception of health care workers as authority figures, fear of disclosure of own and/or child's HIV status, lack of psychosocial support, and intent to shorten the life of the child. A complex array of cultural, economic, and psychosocial factors creates barriers for HIV-infected women to participate in early infant HIV testing and care programs. For optimal impact of EID and infant ART, reasons for poor uptake should be better understood and addressed in a culturally sensitive manner. PMID:22348314

    The electronic properties of a perovskite Fe4+ oxide, CaCu3Fe4O12, pressurized in a diamond anvil cell at pressures up to 50 GPa, were investigated by X-ray diffraction, electrical resistance measurements, X-ray absorption spectroscopy, and 57Fe Mössbauer spectroscopy. The first transformation from a charge-disproportionated (Fe3+ and Fe5+) semiconducting high-spin state to an approximately charge-uniform (Fe(4-δ)+ and Fe(4+δ)+) metallic high-spin state occurred at ˜15 GPa. This was followed by a second transformation to a completely charge-uniform (Fe4+) metallic low-spin state at ˜30 GPa. This is the first observation of pressure-induced two-step suppression of charge disproportionation in perovskite iron oxides.

    Superoxide reacts with carbonate solvents in Li–air batteries. Tris(pentafluorophenyl)borane is found to catalyze a more rapid superoxide (O2-) disproportionation reaction than the reaction between superoxide and propylene carbonate (PC). With this catalysis, the negative impact of the reaction between the electrolyte and O2-produced by the O2 reduction can be minimized. A simple kinetic study using ESR spectroscopy was reported to determine reaction orders and rate constants for the reaction between PC and superoxide, and the disproportionation of superoxide catalyzed by Tris(pentafluorophenyl)borane and Li ions. As a result, the reactions are found to be first order and the rate constants aremore » 0.033 s-1 M-1, 0.020 s-1 M-1and 0.67 s-1M-1 for reactions with PC, Li ion and Tris(pentafluorophenyl)borane, respectively.« less

    Background Uncertainty exists about the appropriate use of screening mammography among older women because comorbid illnesses may diminish the benefit of screening. We examined the risk of adverse tumor characteristics and false positive rates according to screening interval, age, and comorbidity. Methods From January 1999 to December 2006, data were collected prospectively on 2993 older women with breast cancer and 137 949 older women without breast cancer who underwent mammography at facilities that participated in a data linkage between the Breast Cancer Surveillance Consortium and Medicare claims. Women were aged 66 to 89 years at study entry to allow for measurement of 1 year of preexisting illnesses. We used logistic regression analyses to calculate the odds of advanced (IIb, III, IV) stage, large (>20 millimeters) tumors, and 10-year cumulative probability of false-positive mammography by screening frequency (1 vs 2 years), age, and comorbidity score. The comorbidity score was derived using the Klabunde approximation of the Charlson score. All statistical tests were two-sided. Results Adverse tumor characteristics did not differ statistically significantly by comorbidity, age, or interval. Cumulative probability of a false-positive mammography result was higher among annual screeners than biennial screeners irrespective of comorbidity: 48.0% (95% confidence interval [CI] = 46.1% to 49.9%) of annual screeners aged 66 to 74 years had a false-positive result compared with 29.0% (95% CI = 28.1% to 29.9%) of biennial screeners. Conclusion Women aged 66 to 89 years who undergo biennial screening mammography have similar risk of advanced-stage disease and lower cumulative risk of a false-positive recommendation than annual screeners, regardless of comorbidity.

    Background Uncertainty exists about the appropriate use of screening mammography among older women because comorbid illnesses may diminish the benefit of screening. We examined the risk of adverse tumor characteristics and false positive rates according to screening interval, age, and comorbidity. Methods From January 1999 to December 2006, data were collected prospectively on 2993 older women with breast cancer and 137 949 older women without breast cancer who underwent mammography at facilities that participated in a data linkage between the Breast Cancer Surveillance Consortium and Medicare claims. Women were aged 66 to 89 years at study entry to allow for measurement of 1 year of preexisting illnesses. We used logistic regression analyses to calculate the odds of advanced (IIb, III, IV) stage, large (>20 millimeters) tumors, and 10-year cumulative probability of false-positive mammography by screening frequency (1 vs 2 years), age, and comorbidity score. The comorbidity score was derived using the Klabunde approximation of the Charlson score. All statistical tests were two-sided. Results Adverse tumor characteristics did not differ statistically significantly by comorbidity, age, or interval. Cumulative probability of a false-positive mammography result was higher among annual screeners than biennial screeners irrespective of comorbidity: 48.0% (95% confidence interval [CI] = 46.1% to 49.9%) of annual screeners aged 66 to 74 years had a false-positive result compared with 29.0% (95% CI = 28.1% to 29.9%) of biennial screeners. Conclusion Women aged 66 to 89 years who undergo biennial screening mammography have similar risk of advanced-stage disease and lower cumulative risk of a false-positive recommendation than annual screeners, regardless of comorbidity.

    Very little is known about labor health among Korean women workers, who have been left behind by the occupational safety and health institutions. In this article, we examine, from a gender perspective, the occupational safety and health (OSH) statistics, institutions, and the struggles of women workers, and discuss how to make a society where women workers become and stay healthy. The problems Korean women workers face have both universal and unique aspects. On the one hand, they tend to be exposed to "invisible hazards" and to disproportionately suffer from neo-liberal policies, as do women workers in other countries. On the other hand, Korean women workers are still positioned under the strong patriarchy found in pre-modern societies. The examples of struggle presented here come out of this condition; those struggles by women workers and support from concerned specialists have played an important role in overcoming patriarchy and protecting health rights for women workers.

    Oxidation kinetics of iodide and HOI/OI(-) by permanganate were studied in the pH range of 5.0-10.0. Iodide oxidation and iodate formation were faster at lower pH. The apparent second-order rate constants (kobs) for iodide oxidation by permanganate decrease with increasing pH from 29 M(-1) s(-1) at pH 5.0 and 6.9 M(-1) s(-1) at pH 7.0 to 2.7 M(-1) s(-1) at pH 10.0. kobs for HOI abatement are 56 M(-1) s(-1) at pH 5.0, 2.5 M(-1) s(-1) at pH 7.0, and 173 M(-1) s(-1) at pH 10.0. Iodate yields over HOI abatement decrease from 98% at pH 6.0 to 33% for pH ≥ 9.5, demonstrating that HOI disproportionation dominates HOI transformation by permanganate at pH ≥ 8.0. MnO2 formed as a product from permanganate reduction, oxidizes HOI to iodate for pH < 8.0, and promotes HOI disproportionation for pH ≥ 8.0. The rate of HOI oxidation or disproportionation induced by MnO2 is much lower than for permanganate. During treatment of iodide-containing waters, the potential for iodinated disinfection byproducts (I-DBPs) formation is highest at pH 7.0-8.0 due to the long lifetime of HOI. For pH < 6.0, HOI/I2 is quickly oxidized by permanganate to iodate, whereas for pH ≥ 8.0, HOI/OI(-) undergoes a fast permanganate-mediated disproportionation. PMID:27003721

    A mesophilic, anaerobic, gram-negative bacterium, strain SB164P1, was enriched and isolated from oxidized marine surface sediment with elemental sulfur as the sole energy substrate in the presence of ferrihydrite. Elemental sulfur was disproportionated to hydrogen sulfide and sulfate. Growth was observed exclusively in the presence of a hydrogen sulfide scavenger, e.g., ferrihydrite. In the absence of a scavenger, sulfide and sulfate production were observed but no growth occurred. Strain SB164P1 grew also by disproportionation of thiosulfate and sulfite. With thiosulfate, the growth efficiency was higher in ferrihydrite-supplemented media than in media without ferrihydrite. Growth coupled to sulfate reduction was not observed. However, a slight sulfide production occurred in cultures incubated with formate and sulfate. Strain SB164P1 is the first bacterium described that grows chemolithoautotrophically exclusively by the disproportionation of inorganic sulfur compounds. Comparative 16S rDNA sequencing analysis placed strain SB164P1 into the delta subclass of the class Proteobacteria. Its closest relative is Desulfocapsa thiozymogenes, and slightly more distantly related are Desulfofustis glycolicus and Desulforhopalus vacuolatus. This phylogenetic cluster of organisms, together with members of the genus Desulfobulbus, forms one of the main lines of descent within the delta subclass of the Proteobacteria. Due to the common phenotypic characteristics and the phylogenetic relatedness to Desulfocapsa thiozymogenes, we propose that strain SB164P1 be designated the type strain of Desulfocapsa sulfoexigens sp. nov.

  19. Impact of a women's program for science, mathematics and engineering on undergraduate women: Activity systems on the periphery

    Kahveci, Ajda

    National reports such as National Science Foundation's highlight women's disproportionate distribution and differential treatment in the science, mathematics, and engineering (SM&E) fields, in both education and the workforce in the US. Women are less likely than men to choose a career that involves SM&E, and are more likely than men to earn bachelor's degrees in non-science and non-engineering fields. The need for support and encouragement is obvious for women already in college intending to pursue a major in a SM&E field. Comprehensive support networks can be and are established through programs for women entering college and willing to pursue careers in SM&E fields. The context of this research was the Program for Women in Science, Engineering and Mathematics (PWISEM) established in 2001 by a Southern teaching and research university in the US. I constructed a thorough theoretical lens by interweaving the theory of situated learning/legitimate peripheral participation and the cultural-historical activity theory. I explored the interactions and contradictions that affected the science identity formation of the PWISEM students, how they identified themselves as future scientists, and the key factors PWISEM involved in motivating and supporting women students in their intended SM&E majors. The design of the research was dominant-less dominant, the dominant approach being qualitative and the less-dominant being quantitative. The Program was successful in fostering the participation and retention of undergraduate women in SM&E. However, the women in the Program were more likely to internalize the status quo in the SM&E realms without actively challenging it (liberal feminist approach). To change the masculine culture embedded in SM&E, engaging in activism is essential. This research suggests that in fact, programs like PWISEM provide promising contexts for reforming the SM&E culture to be more appealing and inclusive of all. I suggest that there can be both explicit and implicit ways of transformation within such contexts and argue that the implicit approach is more powerful. This research also informs the theory of situated learning in that newcomer interactions are a key aspect and their actions should be understood to involve much more than knowledge circulation.

  20. Evidence and characteristics of hydrolytic disproportionation of organic matter during metasomatic processes

    2001-11-01

    Petroleum-geochemical analyses of carbonaceous regionally metamorphosed rocks, carbonaceous rocks from ore deposits, and alkalic plutonic rocks from diverse settings, demonstrated the presence of very low to moderately low concentrations of solvent-extractable organic matter, this observation in spite of the fact that some of these rocks were exposed to extremely high metamorphic temperatures. Biomarker and δ 13C analyses established that the extractable organic matter originated as sedimentary-derived hydrocarbons. However, the chemistry of the extractable bitumen has been fundamentally transformed from that found in sediment bitumen and oils. Asphaltenes and resins, as defined in the normal petroleum-geochemical sense, are completely missing. The principal aromatic hydrocarbons present in oils and sediment bitumens (especially the methylated naphthalenes) are either in highly reduced concentrations or are missing altogether. Instead, aromatic hydrocarbons typical of sediment bitumens and oils are very minor, and a number of unidentified compounds and oxygen-bearing compounds are dominant. Relatively high concentrations of alkylated benzenes are typical. The polar "resin" fraction, eluted during column chromatography, is the principal compound group, by weight, being composed of six to eight dominant peaks present in all samples, despite the great geologic diversity of the samples. These, and other, observations suggest that a strong drive towards equilibrium exists in the "bitumen." Gas chromatograms of the saturated hydrocarbons commonly have a pronounced hump in both the n-paraffins and naphthenes, centered near the C 19 to C 26 carbon numbers, and a ubiquitous minimum in the n-paraffin distribution near n-C 12 to n-C 14. Multiple considerations dictate that the bitumen in the samples is indigenous and did not originate from either surficial field contamination or from laboratory procedures. Our observations are consistent with the hydrolytic disproportionation of organic matter (HDOM), in which water and organic matter, including hydrocarbons, easily exchange hydrogen or oxygen with one another under certain conditions (Helgeson et al., 1993). The process appears to take place via well-known organic-chemical redox reaction pathways and is most evident in open-fluid systems. The conclusion that HDOM took place in the analyzed samples, thus producing the chemistry of the extractable bitumen, is supported by numerous previously published organic-geochemical studies of metamorphic, volcanic, plutonic, and ore-deposit-related rocks by other investigators. HDOM is suggested as an unrecognized geologic agent of fundamental importance. The process appears to control major chemical reactions in diverse geologic environments including, but not limited to, petroleum geology and geochemistry, regional metamorphism, and base- and precious-metal ore deposition.

  1. Conditionally rare taxa disproportionately contribute to temporal changes in microbial diversity.

    Microbial communities typically contain many rare taxa that make up the majority of the observed membership, yet the contribution of this microbial "rare biosphere" to community dynamics is unclear. Using 16S rRNA amplicon sequencing of 3,237 samples from 42 time series of microbial communities from nine different ecosystems (air; marine; lake; stream; adult human skin, tongue, and gut; infant gut; and brewery wastewater treatment), we introduce a new method to detect typically rare microbial taxa that occasionally become very abundant (conditionally rare taxa [CRT]) and then quantify their contributions to temporal shifts in community structure. We discovered that CRT made up 1.5 to 28% of the community membership, represented a broad diversity of bacterial and archaeal lineages, and explained large amounts of temporal community dissimilarity (i.e., up to 97% of Bray-Curtis dissimilarity). Most of the CRT were detected at multiple time points, though we also identified "one-hit wonder" CRT that were observed at only one time point. Using a case study from a temperate lake, we gained additional insights into the ecology of CRT by comparing routine community time series to large disturbance events. Our results reveal that many rare taxa contribute a greater amount to microbial community dynamics than is apparent from their low proportional abundances. This observation was true across a wide range of ecosystems, indicating that these rare taxa are essential for understanding community changes over time. Importance: Microbial communities and their processes are the foundations of ecosystems. The ecological roles of rare microorganisms are largely unknown, but it is thought that they contribute to community stability by acting as a reservoir that can rapidly respond to environmental changes. We investigated the occurrence of typically rare taxa that very occasionally become more prominent in their communities ("conditionally rare"). We quantified conditionally rare taxa in time series from a wide variety of ecosystems and discovered that not only were conditionally rare taxa present in all of the examples, but they also contributed disproportionately to temporal changes in diversity when they were most abundant. This result indicates an important and general role for rare microbial taxa within their communities. PMID:25028427

    Rationale High-precision hydrogen isotope ratio analysis of nitrogen-bearing organic materials using high-temperature conversion (HTC) techniques has proven troublesome in the past. Formation of reaction products other than molecular hydrogen (H2) has been suspected as a possible cause of incomplete H2 yield and hydrogen isotopic fractionation. Methods The classical HTC reactor setup and a modified version including elemental chromium, both operated at temperatures in excess of 1400 °C, have been compared using a selection of nitrogen-bearing organic compounds, including caffeine. A focus of the experiments was to avoid or suppress hydrogen cyanide (HCN) formation and to reach quantitative H2 yields. The technique also was optimized to provide acceptable sample throughput. Results The classical HTC reaction of a number of selected compounds exhibited H2 yields from 60 to 90 %. Yields close to 100 % were measured for the experiments with the chromium-enhanced reactor. The δ2H values also were substantially different between the two types of experiments. For the majority of the compounds studied, a highly significant relationship was observed between the amount of missing H2and the number of nitrogen atoms in the molecules, suggesting the pyrolytic formation of HCN as a byproduct. A similar linear relationship was found between the amount of missing H2 and the observed hydrogen isotopic result, reflecting isotopic fractionation. Conclusions The classical HTC technique to produce H2 from organic materials using high temperatures in the presence of glassy carbon is not suitable for nitrogen-bearing compounds. Adding chromium to the reaction zone improves the yield to 100 % in most cases. The initial formation of HCN is accompanied by a strong hydrogen isotope effect, with the observed hydrogen isotope results on H2 being substantially shifted to more negative δ2H values. The reaction can be understood as an initial disproportionation leading to H2 and HCN with the HCN-hydrogen systematically enriched in 2H by more than 50 ‰. In the reaction of HCN with chromium, H2 and chromium-containing solid residues are formed quantitatively.

  3. The Disproportionate and Potentially Negative Influence of Research Universities on the Quality of Geoscience Education

    There is a large and growing body of research indicating that post-secondary education in science, technology, engineering, and mathematics (STEM) fields is failing to prepare citizens for the 21st century economy. Introductory STEM courses are vital for preparing science majors for their fields of study and are the only exposure to science many college students will receive, but the quality of teaching in these courses is often not informed by research on teaching and learning. Research universities play an especially prominent role in the design of introductory courses. While research and doctoral universities account for only about 6% of all higher education institutions, they confer 32 per cent of the baccalaureate degrees, and 56 per cent of the baccalaureates earned by recent recipients of science and engineering doctorates. By assuming that larger introductory classes occur at research institutions one can estimate that a dominant number of students receiving introductory instruction in the geosciences are probably occurring at research institutions. Moreover, research universities produce the majority of tenure-track faculty who will later teach at four-year colleges, so the role of research institutions in the influence of introductory course design is expected to be disproportionately large. While introductory courses at research universities play a influential role in how such courses are designed, the teaching of introductory courses is too often viewed as an undesirable assignment for instructors at those institutions. The effort seems unrewarding with incentives for improving teaching at research institutions perceived as modest at best, if not negative. It is commonly perceived that teaching introductory courses will decrease opportunities for teaching higher-level courses to graduate students and/or to conduct research. Furthermore, even for those interested in improving their pedagogical methods, current approaches to professional development are generally difficult to scale and/or costly to institutions and outside instructors' normal workflow. This presentation reports on the results of surveys of research university instructors in an attempt to quantify the state of the introductory course. The surveys attempt to identify common barriers to improvement. Based on these surveys strategies for how to best implement systemic change in introductory courses at research universities are presented in the hope of stimulating discussion and a call to action.

    Probiotic supplementation to a mother during the perinatal period can have a positive impact on the breast milk composition. The aim of our study was to evaluate the effect of oral supplementation with the probiotic VSL#3, during late pregnancy and lactation, on breast milk levels of beneficial bacteria and some functional components (oligosaccharides and lactoferrin) potentially able to have a positive influence on the microbiota. Breast milk microbiota was analyzed by conventional and quantitative real-time PCR. In a double-blind, placebo-controlled, randomized trial, 66 women took daily either the probiotic (n=33) or a placebo (n=33). Intergroup analysis demonstrated that the amounts of both lactobacilli and bifidobacteria were significantly higher in the colostrum and mature milk of the mothers taking VSL#3 in comparison to those taking placebo. The analysis of bacterial strains and species present in breast milk of VSL#3 supplemented mothers indicated that the administered probiotic microorganisms did not pass from maternal gut to mammary gland. In women with vaginal delivery, significantly higher amounts of lactobacilli and bifidobacteria were detected in colostrum and mature milk of probiotic treated group in comparison to placebo group, whereas no significant difference was observed between groups in women who had caesarean section, neither in colostrum nor in mature milk. Milk levels of oligosaccharides and lactoferrin were similar in placebo and probiotic supplemented groups at all timepoints and regardless of the mode of delivery. Our results indicate a probiotic-dependent modulation of breast milk microbiota in vaginally delivering women, possibly exerted through a systemic effect. PMID:25836922

    The reduction of 7,7,8,8-tetracyanoquinodimethane (TCNQ) generates a π radical anion, TCNQrad -, that dimerizes in methanol solution. This dimer ([TCNQ]22-) exhibits a charge-transfer absorption peak at 620 nm and will disproportionate to give TCNQ and TCNQ2- in response to excitation within this charge-transfer band. The present study examined the electronic dynamics of [TCNQ]22- disproportionation. The disproportionation was found to proceed in two steps. Electron transfer, representing the first step, occurred within the 10 fs pulse window, followed by the actual dissociation, within 350 fs. The emission lifetime of the singlet excited state of TCNQ2- was estimated to be 900 fs.

    Systemic Lupus Erythematosus (SLE) negatively impacts life quality, disproportionately affecting women and UK ethnic minorities. The study aimed to explore how UK South Asian women with SLE make sense of their social and interpersonal experiences, within the context of their ethnicity and perceived cultural influences. A qualitative design was employed to collect data from a homogenous sample of six South Asian women with SLE. Semi-structured interviews elicited participants' experiences of living with SLE and data were analysed using Interpretative Phenomenological Analysis. Master themes were (1) 'SLE: Complexities and Ironies', (2) 'The Power of SLE', (3) 'A Sense of Personal Responsibility and Accountability', (4) 'Essential Relationships: Qualities and Consequences' and (5) 'Struggling in Public View'. Findings revealed that illness, function and emotion were experienced as interrelated, and psychosocial issues were a powerful feature in SLE illness processes. Body image concerns, difficulties maintaining roles and the perceived views of others, triggered embarrassment and withdrawal, negatively influencing social function and relationships. Interestingly, explicit references to ethnicity and culture were minimal, suggesting that for these women, the key features of experience tended to reflect those of other SLE groups. These findings call for an integrated, biopsychosocial and multidisciplinary approach to health care provision in this area. PMID:25307703

    Sexual minority men and transgender women are disproportionately affected by HIV in Guatemala. Innovative prevention strategies are urgently needed to address these disparities. While social network approaches are frequently used to reach sexual minorities, little is known about the unique network characteristics among sub-groups. We conducted in-depth qualitative interviews with 13 gay-identifying men, eight non-gay-identifying men who have sex with men (MSM) and eight transgender women in Guatemala City. Using narrative and thematic coding procedures, we identified distinct patterns in the size, composition, and overlap between social and sexual networks across groups. Gay-identifying men had the largest, most supportive social networks, predominantly comprising family. For both non-gay-identifying MSM and transgender women, friends and sex clients provided more support. Transgender women reported the smallest social networks, least social support, and the most discrimination. HIV prevention efforts should be tailored to the specific sexual minority population and engage with strong ties. PMID:25418236

    The physics community in the U.S. has been concerned about the low participation by women for many years. Although some progress has been made, the percentage of undergraduate women in physics is still less than half that in mathematics and chemistry. While the percentage of women in physics declines at every step up the academic ladder, the largest decrease occurs in the undergraduate years. Therefore it is worthwhile to look at how undergraduate physics departments might make women students comfortable. We have conducted a study of undergraduate physics departments in order to learn "what works" in attracting and retaining women in the undergraduate physics major. With a team of women physicists, we visited nine undergraduate physics departments, five with high participation by women and four with average participation. We also visited six departments in women's colleges, which are known for producing accomplished women in all fields, including science. Three of the 15 schools are historically Black colleges, which produce disproportionate numbers of African-American women scientists. We found that the most important factor in a female-friendly physics department is a warm and inclusive culture that reaches out to introductory students. We also discuss the effects of curriculum, pedagogy, and institutional policy.

    Based on the hypothesis that soy food consumption may influence breast tissue activity, we examined its effect on the production of nipple aspirate fluid (NAF), a possible indicator of breast cancer risk. Of 310 premenopausal women screened, 112 (36%) produced at least 10 ?L of NAF, the minimum for study participation. In a crossover design, we randomized 96 women to 2 groups who, in reverse order, consumed a high-soy diet with 2 soy servings/d (1 serving = 177 mL soy milk, 126 g tofu, or 23 g soy nuts) and a low-soy diet with <3 servings/wk of soy for 6 mo each separated by a 1-mo washout period. During each diet period, 3 NAF samples were obtained (baseline and 3 and 6 mo) using a FirstCyte Aspirator and 4 urine samples (baseline and 1, 3, and 6 mo) were analyzed for isoflavonoids by liquid chromatography tandem MS. Adherence to the study protocol according to 24-h dietary recalls and urinary isoflavonoid excretion was high. The drop-out rate was 15% (n = 14); 82 women completed the intervention. The 2 groups produced similar mean NAF volumes at baseline (P = 0.95) but differed in age and previous soy intake and in their response to the intervention (P = 0.03). In both groups, NAF volume decreased during the first 3 mo of the high-soy diet period and returned to baseline at 6 mo, but there was no effect of the high-soy diet on NAF volume (P = 0.50 for diet; P-interaction = 0.21 for diet with time). Contrary to an earlier report, soy foods in amounts consumed by Asians did not increase breast tissue activity as assessed by NAF volume. PMID:21325473

    Introduction Hyperinsulinaemia and insulin resistance (IR) are key features of polycystic ovary syndrome (PCOS) and metabolic syndrome. The effect of 5 weeks of acupuncture treatment has been investigated in a completed prospective pilot trial (Clinicaltrials.gov: NCT01457209), and acupuncture with electrical stimulation applied to insulin-resistant rats with dihydrotestosterone-induced PCOS was shown to improve insulin sensitivity. Therefore, we now aim to conduct a prospective pilot study to evaluate whether using the same acupuncture treatment protocol given over a longer period of time (6 months) than in the previous pilot trial will improve insulin sensitivity in women with PCOS and IR. Our hypothesis is that acupuncture with combined manual and low-frequency electrical stimulation of the needles will improve insulin sensitivity in women with PCOS and IR. Methods/analysis This is a prospective pilot trial. A total of 112 women with PCOS and IR will be recruited and categorised according to their body mass index (BMI) as normal weight (BMI=18.5−23 kg/m2) or as overweight/obese (BMI>23 kg/m2). Acupuncture will be applied three times per week for 6 months at 30 min per treatment. The primary outcome will be the change in insulin sensitivity before and after 6 months of acupuncture treatment, as measured by an oral glucose tolerance test. Ethics/dissemination Ethical approval of this study has been granted from the ethics committee of the First Affiliated Hospital of Guangzhou Medical University (No. 2013039). Written and informed consent will be obtained from each patient before any study procedure is performed, according to good clinical practice. The results of this trial will be disseminated in a peer-reviewed journal and presented at international congresses. Trial registration numbers NCT02026323 and ChiCTR-OCH-13003921. PMID:25941189

    Stigma due to sexual violence includes family rejection, a complex outcome including economic, behavioral, and physical components. We explored the relationship among conflict-related trauma, family rejection, and mental health in adult women living in rural eastern Democratic Republic of the Congo, who participate in a livestock-based microfinance program, Pigs for Peace. Exposure to multiple and different types of conflict-related trauma, including sexual assault, was associated with increased likelihood of family rejection, which in turn was associated with poorer mental health outcomes. Design of appropriate and effective interventions will require understanding family relationships and exposure to different types of trauma in postconflict environments. PMID:24660941

    Hepatitis B disproportionately affects Asian Americans. Because outreach to promote testing and vaccination can be intensive and costly, we assessed the feasibility of an efficient strategy to identify Asian Americans at risk. Prior research with California’s statewide toll-free phone service where low-income women call for free cancer screening found 50% of English- and Spanish-speaking callers were willing to participate in a study on health topics other than cancer screening. The current study ascertained whether Asian Americans could be recruited. Among 200 eligible callers, 50% agreed to take part (95% confidence interval 43%–57%), a rate comparable to our previous study. Subsequent qualitative interviews revealed that receptivity to recruitment was due to trust in the phone service and women’s need for health services and information. This was a relatively low-intensity intervention in that, on average, only five minutes additional call time was required to identify women at risk and provide a brief educational message. Underserved women from diverse backgrounds may be reached in large numbers through existing communication channels. PMID:24185165

    Knowledge of sexual partners' HIV infection can reduce risky sexual behaviors. Yet, there are no published studies to-date examining prevalence and characteristics associated with knowledge among African-American women living in high poverty communities disproportionately affected by HIV. Using the HIV Prevention Trial Network's (HPTN) 064 Study data, multivariable logistic regression was used to examine individual, partner, and partnership-level determinants of women's knowledge (n=1,768 women). Results showed that women's demographic characteristics alone did not account for the variation in serostatus awareness. Rather, lower knowledge of partner serostatus was associated with having two or more sex partners (OR=0.49, 95%CI: 0.37-0.65), food insecurity (OR=0.68, 95%CI: 0.49-0.94), partner age>35 (OR=0.68, 95%CI: 0.49-0.94), and partner concurrency (OR=0.63, 95%CI: 0.49-0.83). Access to financial support (OR=1.42, 95%CI: 1.05-1.92) and coresidence (OR=1.43, 95%CI: 1.05-1.95) were associated with higher knowledge of partner serostatus. HIV prevention efforts addressing African-American women's vulnerabilities should employ integrated behavioral, economic, and empowerment approaches. PMID:25160901

    The evidence linking body mass index (BMI) to severe OA shows a strong association in the knee. There are limited data exploring the effect of BMI on the risk of joint arthroplasty in a healthy population with long periods of follow up. We compared the self-reported BMI at age 20, measured BMI at baseline, year 5 and year 10 with the year 19 risk of total knee arthroplasty (TKA) in a well-described, population based cohort of healthy women. A total of 733 women attended the 19th year visit, of whom 31 underwent TKA and 676 were used as a control group after 26 were removed for having hip arthoplasty. Using logistic regression, an increase in 1 unit of BMI at baseline was associated with a 10.5% increased risk of TKA (p=0.017) and at year 5 the increased risk is 8.6% (p=0.042). When adjusted for baseline age and smoking, baseline BMI was the only significant predictor of TKA at 10.0% with p=0.024. There was no significant association at 10 years or for change in BMI over time. In this prospective, population based study, BMI predicted the risk of TKA for OA. The risk was greatest at baseline when the patients were in middle age suggesting that this is the most important time to target weight reduction interventions. PMID:21782451

  18. Women and AIDS caregiving: women's work?

    PubMed

    Songwathana, P

    2001-01-01

    In this ethnographic study, I examine personal, kinship, and social obligations and the role of women in the traditional Thai family. Under what circumstances do women take on the responsibility to care or not care, and how do they cope with the disease and care when they are also infected? Fifteen women who were afflicted or affected by HIV/AIDS participated in in-depth interviews and participant observations. Analysis employed mainly qualitative methods following Spradley. I show that women who are responsible for caring for both themselves and others, including members of their immediate families or extended family members, face a double jeopardy by virtue of their inferior role and status. When HIV-infected women experience illness, sometimes they feel split; they are incapable of functioning normally, yet they are obligated to do "What they've got to do." Women as carers feel that they have to care because they want to free someone else from suffering despite the fact that they are also suffering. Women roles as family carers seem to be both psychologically and socially constructed. AIDS care is not just a labour of love, but also is done in the spirit of work following Buddhist beliefs of karma and metta. In conclusion, traditional, persistent gender imbalances and inequalities influence women's sexuality, vulnerability, responsibility, and caregiving. When women become infected with HIV and sick with AIDS, their quality of life drops because of the physical, psychological, cultural value, and economic burdens of care they face. AIDS then necessitates rather than prevents women from fulfilling their multiple roles. Consequently, there is a need for greater support especially among Thai women who are afflicted and affected with AIDS. PMID:11814072

  5. The forgotten casualties: women, children, and environmental change.

    Cutter, S L

    1995-06-01

    The author posits that women and children bear a disproportionate burden of environmental degradation and are in the worst position to mitigate the consequences of deteriorating environmental conditions. This article discusses the concept of environmental equity or fairness and its sociospatial impacts and the different adjustments made by women and children. Environmental equity is both an outcome and a process. Process equity includes the underlying causes of uneven distributions of resources. The 1992 Rio Declaration on Environment and Development defines 27 specific principles that broadly follow three forms of equity: social equity, generational equity, and procedural equity. Social equity is defined as the role of social, economic, and political forces in resource consumption and environmental degradation. Environmental risk is related to locational criteria such as cheap land and transportation access and by the social geography of places. Hazardous waste dumping is used to illustrate inequitable waste disposal in developing countries such as Brazil, Mexico, Nigeria, Lebanon, Syria, Venezuela, Zimbabwe, and South Korea. Generational equity is defined as fairness over time. The issue of permanent radioactive waste disposal is a current issue that has implications for future generations. Three strategies are important in assuring generational equity: the maintenance of natural and cultural diversity; a reduction in environmental degradation; and the provision of equal access to resources. Preservation of parkland is a positive strategy and lack of access to health services and reproductive health care is a negative strategy. Procedural equity is defined as the extent to which regulations are applied fairly. The example is given of higher fines for dumping waste in "nice White communities" compared to minority ones. Environmental law regulating hazardous waste exports has been minimally effective. Women and children are affected by particulate pollution and environmental toxins (lead and pesticides) in the air and water of urban areas and by a composite of poverty, development, and urbanization.

  6. The risk of arsenic induced skin lesions in Bangladeshi men and women is affected by arsenic metabolism and the age at first exposure

    It is known that a high fraction of methylarsonate (MA) in urine is a risk modifying factor for several arsenic induced health effects, including skin lesions, and that men are more susceptible for developing skin lesions than women. Thus, we aimed at elucidating the interaction between gender and arsenic metabolism for the risk of developing skin lesions. This study is part of a population-based case-referent study concerning the risk for skin lesions in relation to arsenic exposure via drinking water carried out in Matlab, a rural area 53km south-east of Dhaka, Bangladesh. We randomly selected 526 from 1579 referents and all 504 cases for analysis of arsenic metabolites in urine using HPLC coupled to inductively coupled plasma mass spectrometry (HPLC-HG-ICPMS). The present study confirm previous studies, with the risk for skin lesions being almost three times higher in the highest tertile of %MA (adjusted OR 2.8, 95% CI: 1.9-4.2, p < 0.001) compared to the lowest tertile. The present study is the first to show that the well documented higher risk for men to develop arsenic-related skin lesions compared to women is mainly explained by the less efficient methylation of arsenic, as defined by a higher fraction of MA and lower fraction of DMA in the urine, among men. Our previously documented lower risk for skin lesions in individuals exposed since infancy, or before, was found to be independent of the observed arsenic methylation efficiency. Thus, it can be speculated that this is due to a programming effect of arsenic in utero.

    The present study investigated the effect of Bifidobacterium animalis ssp. lactis Bf-6 (LMG 24 384) (Bf-6)-supplemented yogurt on colonic transit time (CTT). A triple-blinded, randomised, placebo-controlled, two-period cross-over trial was conducted with sixty-eight women with a self-reported history of straining during bowel movements or hard or lumpy stools in the past 2 years. As per regulatory requirements for probiotic studies, eligible women were generally healthy and not actively constipated at the time of enrolment. Participants consumed both Bf-6 and placebo yogurts for 14 d each in a randomised order, with a 6-week washout period between the treatments. The primary outcome, CTT, was assessed via Sitz marker X-rays. The average CTT was 42·1 h for the active period and 43·3 h for the control period (mean difference 1·2 h, 95 % CI - 4·9, 7·4). Since the statistical tests for the cross-over study implied that the mean CTT for the active and control periods in period 2 were biased, the standard protocol suggests examining the results of only period 1 as a traditional randomised controlled trial. This showed that the mean CTT was 35·2 h for the active period v. 52·9 h for the control period (P= 0·015). Bootstrapping demonstrated that both the mean and median differences remained significant (P= 0·016 and P= 0·045, respectively). Few adverse events were noted, with no differences among the active and control periods. The paired analysis showed no differences between the active and control periods during the cross-over trial. Further trials should be conducted in populations with underlying problems associated with disordered transit to determine the potential value of probiotic supplementation more accurately.

    Superoxide reacts with carbonate solvents in Li–air batteries. Tris(pentafluorophenyl)borane is found to catalyze a more rapid superoxide (O2-) disproportionation reaction than the reaction between superoxide and propylene carbonate (PC). With this catalysis, the negative impact of the reaction between the electrolyte and O2-produced by the O2 reduction can be minimized. A simple kinetic study using ESR spectroscopy was reported to determine reaction orders and rate constants for the reaction between PC and superoxide, and the disproportionation of superoxide catalyzed by Tris(pentafluorophenyl)borane and Li ions. As a result, the reactions are found to be first order and the rate constants are 0.033 s-1 M-1, 0.020 s-1 M-1and 0.67 s-1M-1 for reactions with PC, Li ion and Tris(pentafluorophenyl)borane, respectively.

    The perovskite PbCrO3 is an antiferromagnetic insulator. However, the fundamental interactions leading to the insulating state in this single-valent perovskite are unclear. Moreover, the origin of the unprecedented volume drop observed at a modest pressure of P = 1.6 GPa remains an outstanding problem. We report a variety of in situ pressure measurements including electron transport properties, X-ray absorption spectrum, and crystal structure study by X-ray and neutron diffraction. These studies reveal key information leading to the elucidation of the physics behind the insulating state and the pressure-induced transition. We argue that a charge disproportionation 3Cr(4+) → 2Cr(3+) + Cr(6+) in association with the 6s-p hybridization on the Pb(2+) is responsible for the insulating ground state of PbCrO3 at ambient pressure and the charge disproportionation phase is suppressed under pressure to give rise to a metallic phase at high pressure. The model is well supported by density function theory plus the correlation energy U (DFT+U) calculations. PMID:25624483

    Objective The objective of this study was to examine the dependence of item memory and relational memory on medial temporal lobe (MTL) structures. Patients with amnesia, who either had extensive MTL damage or damage that was relatively restricted to the hippocampus, were tested, as was a matched comparison group. Disproportionate relational memory impairments were predicted for both patient groups, and those with extensive MTL damage were also expected to have impaired item memory. Method Participants studied scenes, and were tested with interleaved two-alternative forced-choice probe trials. Probe trials were either presented immediately after the corresponding study trial (lag 1), five trials later (lag 5), or nine trials later (lag 9) and consisted of the studied scene along with a manipulated version of that scene in which one item was replaced with a different exemplar (item memory test) or was moved to a new location (relational memory test). Participants were to identify the exact match of the studied scene. Results As predicted, patients were disproportionately impaired on the test of relational memory. Item memory performance was marginally poorer among patients with extensive MTL damage, but both groups were impaired relative to matched comparison participants. Impaired performance was evident at all lags, including the shortest possible lag (lag 1). Conclusions The results are consistent with the proposed role of the hippocampus in relational memory binding and representation, even at short delays, and suggest that the hippocampus may also contribute to successful item memory when items are embedded in complex scenes.

    A new approach to perform single-electron transfer living radical polymerization (SET-LRP) in water is described. The key step in this process is to allow full disproportionation of CuBr/Me6TREN (TREN = tris(dimethylamino)ethyl amine to Cu(0) powder and CuBr2 in water prior to addition of both monomer and initiator. This provides an extremely powerful tool for the synthesis of functional water-soluble polymers with controlled chain length and narrow molecular weight distributions (polydispersity index approximately 1.10), including poly(N-isopropylacrylamide), N,N-dimethylacrylamide, poly(ethylene glycol) acrylate, 2-hydroxyethyl acrylate (HEA), and an acrylamido glyco monomer. The polymerizations are performed at or below ambient temperature with quantitative conversions attained in minutes. Polymers have high chain end fidelity capable of undergoing chain extensions to full conversion or multiblock copolymerization via iterative monomer addition after full conversion. Activator generated by electron transfer atom transfer radical polymerization of N-isopropylacrylamide in water was also conducted as a comparison with the SET-LRP system. This shows that the addition sequence of l-ascorbic acid is crucial in determining the onset of disproportionation, or otherwise. Finally, this robust technique was applied to polymerizations under biologically relevant conditions (PBS buffer) and a complex ethanol/water mixture (tequila). PMID:23597244

    Bipolar affective disorder in women is a challenging disorder to treat. It is unique in its presentation in women and characterized by later age of onset, seasonality, atypical presentation, and a higher degree of mixed episodes. Medical and psychiatric co-morbidity adversely affects recovery from the bipolar disorder (BD) more often in women. Co-morbidity, particularly thyroid disease, migraine, obesity, and anxiety disorders occur more frequently in women while substance use disorders are more common in men. Treatment of women during pregnancy and lactation is challenging. Pregnancy neither protects nor exacerbates BD, and many women require continuation of medication during the pregnancy. The postpartum period is a time of high risk for onset and recurrence of BD in women. Prophylaxis with mood stabilizers might be needed. Individualized risk/benefits assessments of pregnant and postpartum women with BD are required to promote the health of the women and to avoid or limit exposure of the fetus or infant to potential adverse effects of medication.

    Women have been migrating at similar rates to men for the past 40 years, and comprised about half of all migrants in 2005. Women and children are most affected by displacement as a result of wars and human trafficking. In some cases, the health of female migrants is improved via integration into better health systems in the host country. More often, however, the health of female migrants is affected negatively. Women are doubly disadvantaged because they are discriminated against as women and as migrants. Female migrants are also highly vulnerable to acts of sexual abuse, rape, and violence. This is especially true for women in refugee camps, whose reproductive health needs are often overlooked. To improve the health of female migrants it is important to develop and implement policies that recognize and insist on the respect of the rights of migrants. PMID:19539929

    Objective African American women are disproportionately burdened by asthma morbidity and mortality, and may be more likely than asthma patients in general to have comorbid health conditions. This study sought to identify the self-management challenges faced by African American women with asthma and comorbidities, how they prioritize their conditions, and behaviors perceived as beneficial across conditions. Methods In-depth interviews were conducted with 25 African-American women (mean age 52 years) with persistent asthma and at least one of the following: diabetes, heart disease, or arthritis. Information was elicited on women’s experiences managing asthma and concurrent health conditions. The constant-comparison analytic method was used to develop and apply a coding scheme to interview transcripts. Key themes and subthemes were identified. Results Participants reported an average of 5.7 comorbidities. Fewer than half of the sample considered asthma their main health problem; these perceptions were influenced by beliefs about the relative controllability, predictability, and severity of their health conditions. Participants reported ways in which comorbidities affected asthma management, including that asthma sometimes took a ‘backseat’ to conditions considered more troublesome or worrisome. Mood problems, sometimes attributed to pain or functional limitations resulting from comorbidities, reduced motivation for self-management. Women described how asthma affected comorbidity management; e.g., by impeding recommended exercise. Some self-management recommendations, such as physical activity and weight control, were seen as beneficial across conditions. Conclusions Multiple chronic conditions that include asthma may interact to complicate self-management of each condition. Additional clinical attention and self-management support may help reduce multimorbidity-related challenges. PMID:24161047

    In the United States, intimate partner violence (IPV) against women disproportionately affects ethnic minorities. Further, disparities related to socioeconomic and foreign-born status impact the adverse physical and mental health outcomes as a result of IPV, further exacerbating these health consequences. This article reviews 36 U.S. studies on the physical (e.g., multiple injuries, disordered eating patterns), mental (e.g., depression, post-traumatic stress disorder), and sexual and reproductive health conditions (e.g., HIV/STIs, unintended pregnancy) resulting from IPV victimization among ethnic minority (i.e., Black/African American, Hispanic/Latina, Native American/Alaska Native, Asian American) women, some of whom are immigrants. Most studies either did not have a sufficient sample size of ethnic minority women or did not use adequate statistical techniques to examine differences among different racial/ethnic groups. Few studies focused on Native American/Alaska Native and immigrant ethnic minority women and many of the intra-ethnic group studies have confounded race/ethnicity with income and other social determinants of health. Nonetheless, of the available data, there is evidence of health inequities associated with both minority ethnicity and IPV. To appropriately respond to the health needs of these groups of women, it is necessary to consider social, cultural, structural, and political barriers (e.g., medical mistrust, historical racism and trauma, perceived discrimination, immigration status) to patient-provider communication and help-seeking behaviors related to IPV, which can influence health outcomes. This comprehensive approach will mitigate the racial/ethnic and socioeconomic disparities related to IPV and associated health outcomes and behaviors. PMID:25551432

    Background. Women infected with human immunodeficiency virus (HIV) are disproportionately affected by human papillomavirus (HPV)–related anogenital disease, particularly with increased immunosuppression. AIDS Clinical Trials Group protocol A5240 was a trial of 319 HIV-infected women in the United States, Brazil, and South Africa to determine immunogenicity and safety of the quadrivalent HPV vaccine in 3 strata based on screening CD4 count: >350 (stratum A), 201–350 (stratum B), and ≤200 cells/µL (stratum C). Methods. Safety and serostatus of HPV types 6, 11, 16, and 18 were examined. HPV serological testing was performed using competitive Luminex immunoassay (HPV-4 cLIA). HPV type-specific seroconversion analysis was done for participants who were seronegative for the given type at baseline. Results. Median age of patients was 36 years; 11% were white, 56% black, and 31% Hispanic. Median CD4 count was 310 cells/µL, and 40% had undetectable HIV-1 load. No safety issues were identified. Seroconversion proportions among women at week 28 for HPV types 6, 11,16, and 18 were 96%, 98%, 99%, and 91%, respectively, for stratum A; 100%, 98%, 98%, and 85%, respectively, for stratum B, and 84%, 92%, 93%, and 75%, respectively, for stratum C. Conclusions. The quadrivalent HPV vaccine targeted at types 6, 11, 16, and 18 was safe and immunogenic in HIV-infected women aged 13–45 years. Women with HIV RNA load >10 000 copies/mL and/or CD4 count <200 cells/µL had lower rates of seroconversion rates. Clinical Trials Registration. NCT00604175. PMID:24723284

    Objective Uterine leiomyomata (UL) are a major contributor to gynecologic morbidity and medical costs, and black women are disproportionately affected by the condition. Previous studies have linked UL to psychosocial stress, including child abuse. We assessed the association between lifetime abuse victimization and UL among 9,910 premenopausal women. Study Design Data were derived from the Black Womens Health Study, a prospective cohort study. In 2005, participants reported their experiences of physical and sexual abuse within each life stage (childhood, adolescence, adulthood). Biennial follow-up questionnaires from 2005 through 2011 ascertained new UL diagnoses. Rate ratios (RR) and 95% confidence intervals (CI) were estimated using Cox regression. Results There were 1,506 incident UL cases diagnosed by ultrasound or surgery. UL incidence was higher among women who reported child abuse, particularly sexual abuse. Relative to no abuse across the lifespan, RRs were 1.16 (CI, 1.021.33) for physical abuse only, 1.34 (CI, 1.091.66) for sexual abuse only, and 1.17 (CI, 0.991.39) for both physical and sexual abuse in childhood. RRs for 13 and ?4 incidents of child sexual abuse were 1.29 (CI, 1.041.61) and 1.41 (CI, 1.071.85), respectively, while RRs for low, intermediate, and high frequencies of child physical abuse were 1.19, 1.04, and 1.23, respectively. The association was strongest for the highest category of child abuse severity (RR=1.57, CI, 1.192.07). No associations were found for teen or adult abuse. Conclusions In the present study, child sexual abuse was an independent risk factor for UL, supporting the hypothesis that childhood adversity increases UL risk. PMID:23295977

    Although self-harm has been observed among patients with eating disorders, the effects of such tendencies on treatment outcomes are unclear. The current study employed structural equation modeling to (a) evaluate the relationship between self-harm and changes in body dissatisfaction and drive for thinness in a large sample of patients (n = 2061) who underwent inpatient treatment, and (b) to examine whether the relationship between self-harm and changes in body dissatisfaction and drive for thinness during inpatient treatment remains significant when controlling for change in negative affect during treatment. Results revealed that patients with a history of self-harm reported significantly less reduction in body dissatisfaction and drive for thinness following treatment. Patients experiencing less change in negative affect also reported significantly less reduction in body dissatisfaction and drive for thinness after discharge from treatment. However, the association between history of self-harm and reduction in body dissatisfaction and drive for thinness after treatment became non-significant when controlling for change in negative affect. This pattern of findings was also replicated among patients with a primary diagnosis of anorexia nervosa (n = 845), bulimia nervosa (n = 565), and eating disorder not otherwise specified (n = 651). The implications of these findings for delineating the specific role of self-harm in the nature and treatment of eating disorders are discussed. PMID:25868550

    The author reports on travel in the Philippines, Malaysia, Sri Lanka, and Pakistan, and conditions she found affecting development. Development for women in the Philippines has been hampered by a dichotomy between home economics and agricultural work. Although the majority of students in agriculture are women, many village cooperatives have been formed with less than 10% women members. Malaysia has a high level of education; development projects can easily be implemented. The National Association of Women's Institutes of Peninsular Malaysia (NAWIPM) emphasizes training for rural women. Its activiti include nursuries, poultry raising, home improvement, cooperatives, and income generating projects such as catering and tailoring. As in the Philippines ther is an important Muslim minority; Muslim women lag behind other Sri Lankans in education. The Mahila Samiti is the organization which trains rural women i some 1500 chapters. The women of Pakistan have the greatest need for assistance. Less than 15% Pakistan women are literate; their enrollment in school lags far behind the boys. The All Pakistan Women's Association works on problems of development through its Nutrition Education Training Courses. The centers have begun poultry raising and gardening as parts of its program.

    The purpose of this study was to evaluate the effect of high-intensity resistance exercise (RE) sessions on blood pressure (BP), heart rate (HR), cardiac autonomic modulation, and forearm blood flow (FBF). Sixteen trained hypertensive women (n = 16, 56 3 years) completed the following 3 experimental sessions: control (CS), RE at 50% (EX50%), and RE at 80% (EX80%) of 1 repetition maximum (1RM). Both EX50% and EX80% comprised a set of 10 repetitions of 10 exercises, with an interval of 90 seconds between exercises. Measurements were taken preintervention and postintervention (at 10, 30, 50, 70, and 90 minutes of recovery). Reductions in systolic/diastolic BP after exercise were greater in EX80% (largest declines, -29 4/-14 5 mm Hg) than EX50% (largest declines, -18 6/-8 5 mm Hg, p ? 0.05). Heart rate and cardiac sympathovagal balance (LF/HF) increased more in relation to pre-exercise values in EX80% than EX50% (largest increases 96 3 vs. 90 4 bmin, LF/HF = 1.77 0.25 vs. 1.40 0.20, respectively, p ? 0.05). Increases in FBF and hyperemia was also higher in EX80% than EX50% compared with pre-exercise (4.97 0.28 vs. 4.36 0.27 mlmin100 ml and 5.90 0.20 vs. 5.38 0.25 mlmin100 ml; p ? 0.05, respectively). These results suggest that RE of higher intensity promoted greater postexercise hypotension accompanied by greater increases in FBF, vasodilator response, HR, and cardiac sympathovagal balance.

    Background/objectives: Dietary triacylglycerols containing palmitic acid in the sn-2 position might impair insulin release and increase plasma glucose. Subjects/Methods: We used a cross-over designed feeding trial in 53 healthy Asian men and women (20–50 years) to test this hypothesis by exchanging 20% energy of palm olein (PO; control) with randomly interesterified PO (IPO) or high oleic acid sunflower oil (HOS). After a 2-week run-in period on PO, participants were fed PO, IPO and HOS for 6 week consecutively in randomly allocated sequences. Fasting (midpoint and endpoint) and postprandial blood at the endpoint following a test meal (3.54 MJ, 14 g protein, 85 g carbohydrate and 50 g fat as PO) were collected for the measurement of C-peptide, insulin, glucose, plasma glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1, lipids and apolipoproteins; pre-specified primary and secondary outcomes were postprandial changes in C-peptide and plasma glucose. Results: Low density lipoprotein cholesterol was 0.3 mmol/l (95% confidence interval (95% CI)) 0.1, 0.5; P<0.001) lower on HOS than on PO or IPO as predicted, indicating good compliance to the dietary intervention. There were no significant differences (P=0.58) between diets among the 10 male and 31 female completers in the incremental area under the curve (0–2 h) for C-peptide in nmol.120 min/l: GM (95% CI) were PO 220 (196, 245), IPO 212 (190, 235) and HOS 224 (204, 244). Plasma glucose was 8% lower at 2 h on IPO vs PO and HOS (both P<0.05). Conclusion: Palmitic acid in the sn-2 position does not adversely impair insulin secretion and glucose homeostasis.

    2008-01-01

    The purpose of this study was to evaluate the impact of adopting a Mediterranean diet on dietary cost and energy density in free-living conditions. The 12-wk nutritional intervention consisted of 2 group courses and 7 individual sessions with a dietician in a sample of 73 healthy women. To evaluate the dietary response to the nutritional intervention, a registered dietician administered a FFQ at 0, 6, 12, and 24 wk. Total daily dietary cost was calculated using a price list including all items from the FFQ. Our findings indicated that daily energy cost evaluated at wk 12 vs. wk 0 [1046 +/- 217 vs. 967 +/- 192 kJ/Canadian dollars (CAN$), respectively, P = 0.18] and total daily dietary cost (8.61 +/- 2.13 vs. 8.75 +/- 2.50 CAN$/d per participant, respectively, P = 0.58) did not change. Total daily energy density at wk 12 decreased compared with wk 0 (2.56 +/- 0.76 vs. 2.20 +/- 0.67 kJ/g; P < 0.0001). Adherence to the Mediterranean diet led to increased cost related to vegetables, fruits, legumes, nuts and seeds, canola/olive oil, whole grains, poultry, and fish (P < or = 0.01) and to reduced dietary cost for red meat, refined grains, desserts and sweets, and fast food (P < or = 0.008). In conclusion, these data suggest that adherence to a nutritional intervention program promoting the Mediterranean food pattern is not associated with increased daily dietary cost or energy cost but led to a reduction in energy density. Consequently, increased cost should not be considered a barrier to the promotion and adoption of a Mediterranean diet. PMID:18156404

    Background To assess the covariates of alcohol abuse and the association between alcohol abuse, high-risk sexual behaviors and sexually transmitted infections (STIs). Methods 2,019 women aged 20–44 were randomly selected in a two-stage sampling from the Moshi urban district of northern Tanzania. Participant’s demographic and socio-economic characteristics, alcohol use, sexual behaviors and STIs were assessed. Blood and urine samples were drawn for testing of human immunodeficiency virus, herpes simplex virus, syphilis, chlamydia, gonorrhea, trichomonas and mycoplasma genitalium infections. Results Adjusted analyses showed that a history of physical (OR=2.05; 95% CI: 1.06–3.98) and sexual violence (OR=1.63; 95% CI: 1.05–2.51) was associated with alcohol abuse. Moreover, alcohol abuse was associated with number of sexual partners (OR=1.66; 95% CI: 1.01–2.73). Women who abused alcohol were more likely to report STIs symptoms (OR=1.61; 95% CI: 1.08–2.40). Women who had multiple sexual partners were more likely to have an STI (OR=2.41; 95% CI: 1.46–4.00) compared to women with one sexual partner. There was no direct association between alcohol abuse and prevalence of STIs (OR=0.86; 95% CI: 0.55–1.34). However, alcohol abuse was indirectly associated with STIs through its association with multiple sexual partners. Conclusions The findings of alcohol abuse among physically and sexually violated women as well as the association between alcohol abuse and a history of symptoms of STIs and testing positive for STIs have significant public health implications. In sub-Saharan Africa, where women are disproportionately affected by the HIV epidemic screening for alcohol use should be part of comprehensive STIs and HIV prevention programs. PMID:19060779

    Based on pre-mid-20th-century data, the same photoperiod-related birth seasonality previously observed in schizophrenia was also recently found in neural-tube defects and in extreme left-handedness among professional baseball players. This led to a hypothesis implicating maternal melatonin and other mediators of sunlight actions capable of affecting 4th-embryonic-week developments including neural-tube closure and left-right differentiation of the brain. Here, new studies of baseball players suggest that the same sunlight actions could also affect testosterone-dependent male-female differentiation in the 4-month-old fetus. Independently of hand-preferences, baseball players (n=6829), and particularly the stronger hitters among them, showed a unique birth seasonality with an excess around early-November and an equally significant deficit 6 months later around early-May. In two smaller studies, north-American and other northern-hemisphere born lesbians showed the same strong-hitter birth seasonality while gay men showed the opposite seasonality. The sexual dimorphism-critical 4th-fetal-month testosterone surge coincides with the summer-solstice in early-November births and the winter-solstice in early-May births. These coincidences are discussed and a "melatonin mechanism" is proposed based on evidence that in seasonal breeders maternal melatonin imparts "photoperiodic history" to the newborn by direct inhibition of fetal testicular testosterone synthesis. The present effects could represent a vestige of this same phenomenon in man.

    Affect consciousness (AC) was operationalized as degrees of awareness, tolerance, nonverbal expression, and conceptual expression of nine specific affects. A semistructured interview (ACI) and separate scales were developed to assess these aspects of affect integration. Their psychometric properties were preliminarily explored by having 20 former psychiatric outpatients complete the interview. Concurrent validity was assessed by using DSM-III-R Axis I and II diagnoses, the Health-Sickness Rating Scale, SCL-90-R, and several indexes from the Minnesota Multiphasic Personality Inventory. Satisfactory interrater reliability and high levels of internal consistency supported the construct validity of the measure. Results suggest the most meaningful use of this instrument is in measuring specific affect and overall AC. Clinically, the ACI has provided highly specific and relevant qualitative data for use in planning psychotherapeutic interventions. PMID:22700292

    Background African-American women are disproportionately affected by HIV, accounting for 60% of all cases among women in the United States. Although their race is not a precursor for HIV, the socioeconomic and cultural disparities associated with being African American may increase their risk of infection. Prior research has shown that interventions designed to reduce HIV infection among African-American women must address the life demands and social problems they encounter. The present study used a qualitative exploratory design to elicit information about strategies to prevent HIV transmission among young, low-income African-American women. Methods Twenty five low income African American women, ages 18–29, participated in five focus groups of five women each conducted at a housing project in Houston, Texas, a large demographically diverse metropolitan area that is regarded as one of the HIV/AIDS epicenters in the United States. Each group was audiotaped, transcribed, and analyzed using theme and domain analysis. Results The participants revealed that they had most frequently placed themselves at risk for HIV infection through drugs and drinking and they also reported drug and alcohol use as important barriers to practicing safer sex. The women also reported that the need for money and having sex for money to buy food or drugs had placed them at risk for HIV transmission. About one-third of the participants stated that a barrier to their practicing safe sex was their belief that there was no risk based on their being in a monogamous relationship and feeling no need to use protection, but later learning that their mate was unfaithful. Other reasons given were lack of concern, being unprepared, partner's refusal to use a condom, and lack of money to buy condoms. Finally, the women stated that they were motivated to practice safe sex because of fear of contracting sexually transmitted diseases and HIV, desire not to become pregnant, and personal experience with someone who had contracted HIV. Conclusion This study offers a foundation for further research that may be used to create culturally relevant HIV prevention programs for African-American women. PMID:15774003

    The challenges that face African American women living with HIV are immense. African American women continue to be disproportionately infected and affected by this chronic and life-threatening infection in a complex context of individual experience, interactions with the environment, formal and informal support systems, and cultural belief systems. This article identifies the Theory of Silencing the Self (STS) and a widely known model, the Social Ecological Model (SEM), as a synthesized explanatory framework in helping nurses understand how to address research questions and clinical care that is congruent with the experience of African American women living with HIV infection. In synthesizing the components of these two frameworks, an explanation of the relationship between disempowerment and depression in this population will be uncovered as a key component to making relationships at the individual, family, and community level better. Helping African American women living with HIV infection to explore and address how choosing to be silent across their life systems will advance healthcare adherence as we currently know it to improved self-management of a chronic, gender-specific, culturally-bound experience of depression.

    The thermodynamics of disproportionation of 1,4-benzosemiquinone (BQ{sup {sm bullet}{minus}}) and 1,4-naphthosemiquinone (NQ{sup {sm bullet}{minus}}) in cacodylic-cacodylate buffer at pH 7.1 was studied by electron spin resonance (ESR) spectroscopy and solution calorimetry. The disproportionation of BQ{sup {sm bullet}{minus}} was found to be more exergonic and exothermic than that corresponding to NQ{sup {sm bullet}{minus}} in both aqueous and gas phases. These semiquinones disproportionate about 40 times more exothermically in the gaseous than in the aqueous phase. The differences between the enthalpies of disproportionation corresponding to BQ{sup {sm bullet}{minus}} and NQ{sup {sm bullet}{minus}} are 51 and 14 kJ/mol in the gaseous and aqueous phases, respectively. The heats of hydration of BQ{sup {sm bullet}{minus}} and NQ{sup {sm bullet}{minus}} were determined with a convenient thermochemical cycle based on the enthalpies of disproportionation. The single-ion heats of hydration of BQ{sup {sm bullet}{minus}} and NQ{sup {sm bullet}{minus}} were found to be {minus}360 and {minus}377 kJ/mol, respectively. The heats of hydration of the net negative charge in BQ{sup {sm bullet}{minus}} and NQ{sup {sm bullet}{minus}} were found to be the same.

    A 10-year-old Turkish boy with consanguineous parents was presented with a disproportionately short stature and a nephrotic syndrome. The mild form of Schimke's immuno-osseous dysplasia was diagnosed as the common cause. This rare, autosomal recessive osteochondrodysplasia is characterised by spondyloepiphyseal dysplasia, facial dysmorphism, T-cell immunodeficiency and progressive renal failure due to focal segmental glomerulosclerosis. In Schimke's immuno-osseous dysplasia, a severe early-onset form and a milder later-onset form can be distinguished on the basis of the clinical course. The patient was treated by fluid and salt restriction, enalapril and later also losartan, which led to a decrease in the proteinuria and an increase in serum albumin concentration. Two years later, the renal function was still normal. PMID:16223078

    Objective: To determine the retailer and community level factors associated with frequent and disproportionate sales of handguns that are later used in violent and firearm related crimes (VFC handguns). Design: Cross sectional. The authors used California records to identify all handguns sold by study subjects during 1996–2000 and federal gun tracing records to determine which of these guns had been recovered by a police agency in the US or elsewhere and traced by 30 September 2003. Subjects and setting: The 421 licensed gun retailers in California selling at least 100 handguns annually during 1996–2000. Main outcome measure: The number of VFC handguns per 1000 gun years of exposure. Differences are expressed as incidence rate ratios (RR) with 95% confidence intervals (CI). Results: Subjects accounted for 11.7% of California retailers with handgun sales, 81.5% of handgun sales, and 85.5% of VFC handguns. Among subjects, the 3426 VFC handguns accounted for 48.0% of all traced handguns and 65.0% of those linked to a specified crime. The median VFC handgun trace rate was 0.5/1000 gun years (range 0–8.8). In multivariate analysis, this rate increased substantially for each single-point increase in the percentage of proposed sales that were denied because the purchasers were prohibited from owning guns (RR 1.43; 95% CI 1.32 to 1.56), and was increased for pawnbrokers (RR 1.26; 95% CI 1.02 to 1.55). Community level crime rates and sociodemographics had little predictive value. Conclusions: Risk factors, largely determined at the retailer level, exist for frequent and disproportionate sales of handguns that are later used in violent and firearm related crimes. Screening to identify high risk retailers could be undertaken with data that are already available. PMID:16326771

    Changes in lifestyles and body weight affected mammal life-history evolution but little is known about how they shaped species' sensory systems. Since auditory sensitivity impacts communication tasks and environmental acoustic awareness, it may have represented a deciding factor during mammal evolution, including apes. Here, we statistically measure the influence of phylogeny and allometry on the variation of five cochlear morphological features associated with hearing capacities across 22 living and 5 fossil catarrhine species. We find high phylogenetic signals for absolute and relative cochlear length only. Comparisons between fossil cochleae and reconstructed ape ancestral morphotypes show that Australopithecus absolute and relative cochlear lengths are explicable by phylogeny and concordant with the hypothetized ((Pan,Homo),Gorilla) and (Pan,Homo) most recent common ancestors. Conversely, deviations of the Paranthropus oval window area from these most recent common ancestors are not explicable by phylogeny and body weight alone, but suggest instead rapid evolutionary changes (directional selection) of its hearing organ. Premodern (Homo erectus) and modern human cochleae set apart from living non-human catarrhines and australopiths. They show cochlear relative lengths and oval window areas larger than expected for their body mass, two features corresponding to increased low-frequency sensitivity more recent than 2 million years ago. The uniqueness of the "hypertrophied" cochlea in the genus Homo (as opposed to the australopiths) and the significantly high phylogenetic signal of this organ among apes indicate its usefulness to identify homologies and monophyletic groups in the hominid fossil record.

    Changes in lifestyles and body weight affected mammal life-history evolution but little is known about how they shaped species’ sensory systems. Since auditory sensitivity impacts communication tasks and environmental acoustic awareness, it may have represented a deciding factor during mammal evolution, including apes. Here, we statistically measure the influence of phylogeny and allometry on the variation of five cochlear morphological features associated with hearing capacities across 22 living and 5 fossil catarrhine species. We find high phylogenetic signals for absolute and relative cochlear length only. Comparisons between fossil cochleae and reconstructed ape ancestral morphotypes show that Australopithecus absolute and relative cochlear lengths are explicable by phylogeny and concordant with the hypothetized ((Pan,Homo),Gorilla) and (Pan,Homo) most recent common ancestors. Conversely, deviations of the Paranthropus oval window area from these most recent common ancestors are not explicable by phylogeny and body weight alone, but suggest instead rapid evolutionary changes (directional selection) of its hearing organ.

    Background. We explored healthcare provider perspectives and practices regarding safer conception counseling for HIV-affected clients. Methods. We conducted semistructured interviews with 38 providers (medical and clinical officers, nurses, peer counselors, and village health workers) delivering care to HIV-infected clients across 5 healthcare centres in Mbarara District, Uganda. Interview transcripts were analyzed using content analysis. Results. Of 38 providers, 76% were women with median age 34 years (range 24–57). First, we discuss providers' reproductive counseling practices. Emergent themes include that providers (1) assess reproductive goals of HIV-infected female clients frequently, but infrequently for male clients; (2) offer counseling focused on “family planning” and maternal and child health; (3) empathize with the importance of having children for HIV-affected clients; and (4) describe opportunities to counsel HIV-serodiscordant couples. Second, we discuss provider-level challenges that impede safer conception counseling. Emergent themes included the following: (1) providers struggle to translate reproductive rights language into individualized risk reduction given concerns about maternal health and HIV transmission and (2) providers lack safer conception training and support needed to provide counseling. Discussion. Tailored guidelines and training are required for providers to implement safer conception counseling. Such support must respond to provider experiences with adverse HIV-related maternal and child outcomes and a national emphasis on pregnancy prevention. PMID:27051664

    Globally, women experience a disproportionate burden of disease and death due to inequities in access to basic health care, nutrition, and education. In the face of this disparity, it is striking that leadership in the field of global health is highly skewed towards men and that global health organizations neglect the issue of gender equality in their own leadership. Randomized trials demonstrate that women in leadership positions in governmental organizations implement different policies than men and that these policies are more supportive of women and children. Other studies show that proactive interventions to increase the proportion of women in leadership positions within businesses or government can be successful. Therefore, the authors assert that increasing female leadership in global health is both feasible and a fundamental step towards addressing the problem of women's health. In this Perspective, the authors contrast the high proportion of young female trainees who are interested in academic global health early in their careers with the low numbers of women successfully rising to global health leadership roles. The authors subsequently explore reasons for female attrition from the field of global health and offer practical strategies for closing the gender gap in global health leadership. The authors propose solutions aimed to promote female leaders from both resource-wealthy and resource-poor countries, including leadership training grants, mentorship from female leaders in global professions, strengthening health education in resource-poor countries, research-enabling grants, and altering institutional policies to support women choosing a global health career path.

    African-American women continue to be disproportionately affected by HIV-related morbidity and mortality. To address the burden of HIV/AIDS among this at-risk population, there is need to gain a better understanding of the factors that influence and affect their care-seeking behavior and specifically adherence to antiretroviral treatment. A preliminary qualitative study was conducted with a sample of the target population (n = 10) using grounded theory as the methodological approach. Similarly, 21 healthcare providers - physicians, pharmacists, nurses, and case managers - were then interviewed. A thematic analysis of the transcripts compared care-provider perceptions and narrated experiences with those from the patient participants. Themes related to patient care perceived to enhance medication adherence included (1) provider-patient relationship; (2) holistic and patient-centered care; (3) adequacy of patient education and counseling; (4) modeling adherence behavior; and (5) motivation. Two intervention strategies are proposed - Peer educators as an integral part of the care team and Patient Advisory Groups as a feedback mechanism to enhance effective delivery of patient care in the target population. This exploratory research lays a foundation for the design of targeted interventions to improve linkage to care and enhance medication adherence in African-American women living with HIV/AIDS.

At the time of manuscript submission, Dr Arya was a fellow in the division of infectious diseases at Beth Israel Deaconess Medical Center and Harvard Medical School. African American women are disproportionately affected by the HIV/AIDS epidemic in the United States. To address this disparity, the CDC released a call for targeted communication campaigns in African American communities. The mass media is an HIV/AIDS information source used by African Americans, and media initiatives can be cost-effective for delivering HIV prevention messages. Needed is research in communities at risk to determine the messages needed and the preferred formats and channels with which to deliver the messages so that targeted communication campaigns can be part of the multifaceted approach to ending the HIV/AIDS disparity affecting African American women.

    Background To assess racial differences in functional disability among older women with non-metastatic breast cancer. Methods This is a cross-sectional study. Between April 2008 and December 2012, women aged ?65 years with newly diagnosed stage IIII breast cancer were recruited from ambulatory oncology clinics at an academic center. Prior to receiving any adjuvant treatment participants completed a comprehensive geriatric assessment. The primary outcome was functional disability, defined as dependency in any Basic or Instrumental Activity of Daily Living, Yes or No. Logistic regression analyses were undertaken. Results We enrolled 190 women whose mean age was 75.0 years at diagnosis (SD=7.0, range 6593 years). Thirty-two percent were African-American (AA), and 39 percent had functional disability. Controlling for age, participants with functional disability were more likely to be AA [versus (vs.) non-Hispanic White], Odds ratio (OR) = 4.19, 95% confidence interval (CI) =2.128.27. Fifty-nine percent of the racial difference in functional disability was explained by a higher prevalence of lower income and education among AA. Additionally, the higher prevalence of chronic medical conditions and obesity among AA, after accounting for socioeconomic factors, further explained 40% of the Black-White difference in functional disability. Conclusion Among older women with newly diagnosed non-metastatic breast cancer, functional disability is highly prevalent and African-Americans are disproportionately affected. Interventions to optimize the functional status of at-risk individuals, particularly African-Americans, during and after cancer treatment may improve treatment tolerance and overall survival outcomes.

    2015-01-01

    Suicide is a global public health problem. Asia accounts for 60% of the world's suicides, so at least 60 million people are affected by suicide or attempted suicide in Asia each year. The burden of female suicidal behavior, in terms of total burden of morbidity and mortality combined, is more in women than in men. Women's greater vulnerability to suicidal behavior is likely to be due to gender related vulnerability to psychopathology and to psychosocial stressors. Suicide prevention programmes should incorporate woman specific strategies. More research on suicidal behavior in women particularly in developing countries is needed. PMID:26330640

    Globalization theories have proliferated over the past two decades. However, global developments have yet to be systematically incorporated into theories around violence against women. This article proposes to add a global level to the existing ecological model framework, popularized by Lori Heise in 1998, to explore the relationships between global processes and experiences of violence against women. Data from the Maldives and Cambodia are used to assess how globalized ideologies, economic development and integration, religious fundamentalisms, and global cultural exchange, as components of a larger globalization process, have affected men and women’s experiences and perceptions of violence against women.

    2011-03-01

    Our objective in this study was to determine the effects of a high-protein and high-potential renal acid load (PRAL) diet on calcium (Ca) absorption and retention and markers of bone metabolism. In a randomized crossover design, 16 postmenopausal women consumed 2 diets: 1 with low protein and low PRAL (LPLP; total protein: 61 g/d; PRAL: -48 mEq/d) and 1 with high protein and high PRAL (HPHP; total protein: 118 g/d; PRAL: 33 mEq/d) for 7 wk each separated by a 1-wk break. Ca absorption was measured by whole body scintillation counting of radio-labeled (47)Ca. Compared with the LPLP diet, the HPHP diet increased participants' serum IGF-I concentrations (P < 0.0001), decreased serum intact PTH concentrations (P < 0.001), and increased fractional (47)Ca absorption (mean ± pooled SD: 22.3 vs. 26.5 ± 5.4%; P < 0.05) and urinary Ca excretion (156 vs. 203 ± 63 mg/d; P = 0.005). The net difference between the amount of Ca absorbed and excreted in urine did not differ between 2 diet periods (55 vs. 28 ± 51 mg/d). The dietary treatments did not affect other markers of bone metabolism. In summary, a diet high in protein and PRAL increases the fractional absorption of dietary Ca, which partially compensates for increased urinary Ca, in postmenopausal women. The increased IGF-I and decreased PTH concentrations in serum, with no change in biomarkers of bone resorption or formation, indicate a high-protein diet has no adverse effects on bone health.

    The names of 927 women who are or have been active in meteorology or closely related fields have been obtained from various sources. Of these women, at least 500 are presently active. An estimated 4-5% of the total number of Ph.D.s in meteorology are awarded to women. About 10% of those receiving B.S. and M.S. degrees are women.The work patterns, accomplishments, and salaries of employed women meteorologists have been summarized from 330 responses to questionnaires, as functions of age, family status, part- or full-time working status, and employing institutions. It was found that women meteorologists holding Ph.D.s are more likely than their male counterparts to be employed by universities. As increasing number of women were employed in operational meteorology, although few of them were married and fewer still responsible for children. Several women were employed by private industry and some had advanced into managerial positions, although at the present time, such positions remain out of the reach of most women.The subjective and objective effects of several gender-related factors have been summarized from the comments and responses to the questionnaires. The primary obstacles to advancement were found to be part-time work and the responsibility for children. Part-time work was found to have a clearly negative effect on salary increase as a function of age. prejudicated discrimination and rules negatively affecting women remain important, especially to the older women, and affirmative action programs are generally seen as beneficial.Surprisingly, in contrast to the experience of women in other fields of science, women Ph.D.s in meteorology earn salaries comparable of their employment in government or large corporations and universities where there are strong affirmative action programs and above-average salaries. Based on the responses to the questionnaire, the small size of the meteorological community is also a factor, enabling women to become recognized quickly as individuals. It also may be partially attributed to the relative youth of the women involved. They are too young to have encountered the severe discrimination others experienced in the past, and too young to have reached the barriers that have traditionally prevented women from advancing to higher positions. No figures are available that would allow comparison between salaries of male and female holders of bachelor's and master's degrees.

    Background American Black men who have sex with men (MSM) are disproportionately affected by HIV, but the factors associated with this concentrated epidemic are not fully understood. Methods Black MSM were enrolled in 6 US cities to evaluate a multi-component prevention intervention, with the current analysis focusing on the correlates of being newly diagnosed with HIV compared to being HIV-uninfected or previously diagnosed with HIV. Results HPTN 061 enrolled 1553 Black MSM whose median age was 40; 30% self-identified exclusively as gay or homosexual, 29% exclusively as bisexual, and 3% as transgender. About 1/6th (16.2%) were previously diagnosed with HIV (PD); of 1263 participants without a prior HIV diagnosis 7.6% were newly diagnosed (ND). Compared to PD, ND Black MSM were younger (p<0.001); less likely to be living with a primary partner (p<0.001); more likely to be diagnosed with syphilis (p<0.001), rectal gonorrhea (p = 0.011) or chlamydia (p = 0.020). Compared to HIV-uninfected Black MSM, ND were more likely to report unprotected receptive anal intercourse (URAI) with a male partner in the last 6 months (p<0.001); and to be diagnosed with syphilis (p<0.001), rectal gonorrhea (p = 0.004), and urethral (p = 0.025) or rectal chlamydia (p<0.001). They were less likely to report female (p = 0.002) or transgender partners (p = 0.018). Multivariate logistic regression analyses found that ND Black MSM were significantly more likely than HIV-uninfected peers to be unemployed; have STIs, and engage in URAI. Almost half the men in each group were poor, had depressive symptoms, and expressed internalized homophobia. Conclusions ND HIV-infected Black MSM were more likely to be unemployed, have bacterial STIs and engage in URAI than other Black MSM. Culturally-tailored programs that address economic disenfranchisement, increase engagement in care, screen for STIs, in conjunction with safer sex prevention interventions, may help to decrease further transmission in this heavily affected community.

    Whereas the sulfur isotope effects during the abiotic disproportionation of SO2 were thoroughly investigated in the last years, data on the oxygen isotope signature of produced sulfate is scarce. To fill in this gap in knowledge, we performed laboratory experiments which simulated the abiotic SO2 disproportionation at temperatures ranging from 150C to 320C. In our experiments SO2 disproportionated rapidly into sulfate and elemental sulfur. The oxygen isotope fractionation between produced sulfate and water is in the range of the observed oxygen isotope offset between seawater sulfate and seawater. The isotope fractionations observed for the experiments is likely composed of an initial kinetic oxygen isotope fractionation, which is rapidly overprinted by equilibrium oxygen isotope between sulfate and water (reaching completion probably within a time frame of to 1 hour. Our observations raise the questions if disproportionation of magmatic SO2 in submarine hydrothermal vent systems is an important control for today's seawater sulfate isotope composition, and if so, if marine hydrothermal SO2 disproportiantion shaped the oxygen isotope signature of marine sulfate over geological times.

    Group 13 M(I) compounds often disproportionate into M(0) and M(III). Here, however, we show that the reaction of the M(I) salt of the weakly coordinating alkoxyaluminate [Ga(I)(C6H5F)2](+)[Al(OR(F))4](-) (R(F)=C(CF3)3) with 2,2'-bipyridine (bipy) yields the paramagnetic and distorted octahedral [Ga(bipy)3](2+)(•){[Al(OR(F))4](-)}2 complex salt. While the latter appears to be a Ga(II) compound, both, EPR and DFT investigations assign a ligand-centred [Ga(III){(bipy)3}(•)](2+) radical dication. Surprisingly, the application of the heavier homologue [(I)n(I)(C6H5F)2](+)[Al(OR(F))4](-) leads to aggregation and formation of the homonuclear cationic triangular and rhombic [In3(bipy)6](3+), [In3(bipy)5](3+) and [In4(bipy)6](4+) metal atom clusters. Typically, such clusters are formed under strongly reductive conditions. Analysing the unexpected redox-neutral cationic cluster formation, DFT studies suggest a stepwise formation of the clusters, possibly via their triplet state and further investigations attribute the overall driving force of the reactions to the strong In-In bonds and the high lattice enthalpies of the resultant ligand stabilized [M3](3+){[Al(OR(F))4](-)}3 and [M4](4+){[Al(OR(F))4](-)}4 salts.

    In the present investigation, we take advantage of the ultrafine grain size of NdFeCoB partially hydrogen-disproportionated phases, and prepare anisotropic nanocrystalline magnets with full density and homogenous microstructure and texture by reactive deformation under low pressure. Our results suggest that the pressure could properly promote an occurrence of desorption-recombination reaction due to a shorter-range rearrangement of the atoms, and the newly recombined Nd{sub 2}Fe{sub 14}B grains with fine grain size could undergo deformation immediately after the phase transformation, and then an obvious anisotropy and uniform alignment would be obtained. The maximum magnetic properties, (BH){sub max} = 25.8 MGOe, Br = 11.8 kG, H{sub cj} = 5.5 kOe, were obtained after being treated for 5 min at 820 °C in vacuum. The present study highlights the feasibility to prepare anisotropic nanocrystalline magnets with homogeneous microstructure and a strong (00l) texture of uniform grain size under low pressure.

    Parents of children suffering from disproportionate short stature due to achondroplasia may wish to have surgical leg lengthening carried out for the child. The aim is not to increase height, but rather to achieve physiological proportions in the body. In a systematic review of the literature on the topic dating from the last 20 years, the surgical approaches used for this purpose were analyzed in accordance with the Preferred reporting items for systematic reviews and meta-analyses (PRISMA) criteria. Twelve studies show that to date, involvement of the child in decision-making at the start of treatment has been expected and that it is recommended from the age of 12. In highly heterogeneous patient groups, with varying factors involved and different techniques being used, lengthening (often by more than 10 cm) is described. High complication rates are reported, with many setbacks often requiring repeat surgery. Using PALEY'S multiplier method, the expected standing height, sitting height, and leg length can be predicted and an individualized treatment approach can be planned and operative procedures could be started in early childhood as PERETTI suggests. As the patients are unable to be involved in decision-making as young children, these data may provide a basis for offering differentiated advice to parents, who usually consult a pediatric orthopedist at a very early stage in the child's life.

Here, however, we show that the reaction of the MI salt of the weakly coordinating alkoxyaluminate [GaI(C6H5F)2]+[Al(ORF)4]− (RF=C(CF3)3) with 2,2'-bipyridine (bipy) yields the paramagnetic and distorted octahedral [Ga(bipy)3]2+•{[Al(ORF)4]−}2 complex salt. While the latter appears to be a GaII compound, both, EPR and DFT investigations assign a ligand-centred [GaIII{(bipy)3}•]2+ radical dication. Surprisingly, the application of the heavier homologue [InI(C6H5F)2]+[Al(ORF)4]− leads to aggregation and formation of the homonuclear cationic triangular and rhombic [In3(bipy)6]3+, [In3(bipy)5]3+ and [In4(bipy)6]4+ metal atom clusters. Typically, such clusters are formed under strongly reductive conditions. Analysing the unexpected redox-neutral cationic cluster formation, DFT studies suggest a stepwise formation of the clusters, possibly via their triplet state and further investigations attribute the overall driving force of the reactions to the strong In−In bonds and the high lattice enthalpies of the resultant ligand stabilized [M3]3+{[Al(ORF)4]−}3 and [M4]4+{[Al(ORF)4]−}4 salts.

    Carbon nanotubes (CNTs) with different degree of surface oxidation were used as supports for 5 wt.% Co catalysts. CNTs and Co/CNT catalysts were analyzed by XPS, nitrogen adsorption, TEM and electron diffraction to reveal their structure. High oxidation degree of CNT surface (8.6 at.% of O) and low Co loading led to predominantly amorphous Co species. This resulted in the absence of catalytic activity in both CO and CO2 hydrogenation in opposite to the catalyst supported on less oxidized CNTs (5.4 at.% of O) where Co species were found to be crystalline. Thermal treatment of inactive catalyst in H2 and He led to the formation of Co crystal phase which was active in catalysis. Co particle size in catalyst supported on strongly oxidized CNTs was unchanged during CO hydrogenation in opposite to Co supported on less oxidized CNTs. Carbon shell formation on the surface of amorphous Co particles during CO hydrogenation was revealed, which testified CO disproportionation. Qualitative mechanism of CO hydrogenation on small Co particles was proposed.

  10. Increasing Women in Leadership in Global Health

    Globally, women experience a disproportionate burden of disease and death due to inequities in access to basic health care, nutrition, and education. In the face of this disparity, it is striking that leadership in the field of global health is highly skewed towards men and that global health organizations neglect the issue of gender equality in their own leadership. Randomized trials demonstrate that women in leadership positions in governmental organizations implement different policies than men and that these policies are more supportive of women and children. Other studies show that proactive interventions to increase the proportion of women in leadership positions within businesses or government can be successful. Therefore, the authors assert that increasing female leadership in global health is both feasible and a fundamental step towards addressing the problem of women’s health. In this article, the authors contrast the high proportion of young female trainees who are interested in academic global health early in their careers with the low numbers of women successfully rising to global health leadership roles. The authors subsequently explore reasons for female attrition from the field of global health and offer practical strategies for closing the gender gap in global health leadership. The authors propose solutions aimed to promote female leaders from both resource-wealthy and resource-poor countries, including leadership training grants, mentorship from female leaders in global professions, strengthening health education in resource-poor countries, research-enabling grants, and altering institutional policies to support women choosing a global health career path.

    Purpose Mental health problems disproportionately affect women, particularly during childbearing years. However, there is a paucity of research on the determinants of postpartum mental health problems using representative US populations. Taking a life course perspective, we determined the potential risk factors for postpartum mental health problems, with a particular focus on the role of mental health before and during pregnancy. Methods We examined data on 1,863 mothers from eleven panels of the 1996-2006 Medical Expenditure Panel Survey (MEPS). Poor postpartum mental health was defined using self-reports of mental health conditions, symptoms of mental health conditions, or global mental health ratings of “fair” or “poor.” Results 9.5% of women reported experiencing postpartum mental health problems, with over half of these women reporting a history of poor mental health. Poor pre-pregnancy mental health and poor antepartum mental health both independently increased the odds of having postpartum mental health problems. Staged multivariate analyses revealed that poor antepartum mental health attenuated the relationship between pre-pregnancy and postpartum mental health problems. Additionally, significant disparities exist in women's report of postpartum mental health status. Conclusions While poor antepartum mental health is the strongest predictor of postpartum mental health problems, pre-pregnancy mental health is also important. Accordingly, health care providers should identify, treat, and follow women with a history of poor mental health, as they are particularly susceptible to postpartum mental health problems. This will ensure that women and their children are in the best possible health and mental health during the postpartum period and beyond. PMID:21349740

    The objectives of the International Women's Day are: 1) to celebrate the struggle for women's rights in the economic, social, political, and cultural domain; 2) to reaffirm women's solidarity in the struggle for peace; 3) and to show what women have achieved. In 1988, Uganda's government of the National Resistance Movement created the Ministry of Women in Development. The period 1988-1990 was one of consultations, needs assessment, planning, and recruiting staff for the Ministry. From 1990 to 1993, measurable results have been achieved. The Ministry's gender concerns pertained to the sector policies of the Ministries of Agriculture, Animal Industry and Fisheries, Education, Health, Water, Energy, Minerals, and Environment Protection. Under the Umbrella Project for Women in Development, gender sensitization has been achieved with policy makers in ministries, at district level, and in the media. Gender issues have also been incorporated in the National Political School Curriculum. The Ministry has also trained a corps of 73 women trainers from 38 districts. The Ministry, with funding from DANIDA, collected women's views on the constitution through meetings and seminars in all the districts in the country. Recommendations were submitted in a consolidated report to the Constitution Commission. A pilot para-legal scheme is successfully being implemented in Kamuli district. A community-based pool of legal advisors has been developed. Legal matters that affect both women and men are undertaken at the community level. The economic emancipation of women is a crucial part of the Ministry's mandate. In conjunction with NGOs, pilot credit programs are being run in Mukono, Jinja, Mbale, and Kapchorwa districts. Cross-sectoral programs are in close collaboration with the rural water and sanitation program, the Northern Uganda rehabilitation program, and the integrated Basic Education Pilot Project to be implemented in 8 districts.

    Over the past few years, the decades-long slow but steady increase in participation in physics by undergraduate women has stalled. As the numbers of undergraduate majors in physics increase, the numbers of women are not keeping pace. Moreover, women of color represent a disproportionately small fraction of physicists. This means that women of color, and women in general, are an undertapped pool of talent. Significant variation in the participation of women from one institution to the next suggests that local factors, such as department culture, are important, rather than differences in aptitude, motivation, or preparation. Physicists in the U.S. must redouble their efforts to make physics departments and laboratories places where women and men of all backgrounds can thrive and produce exciting science.

    Women over 65 bear high risk for developing cancer. The risk for developing most cancers grows'with increasing age. Of the 1.13 million people estimated to develop cancer in 1992,362,000 (32 percent) will be women over 65 years old (American Cancer Society, 1992). The few early detection and prevention programs that have focused on this age group have found that the women often have problems with utilization, misconceptions, and plain lack of correct information. Treatment for women over 65 with cancer may differ from that for younger women because of age bias, comorbidity, stage of disease at time of diagnosis, and a lack of research on women of this age. Even quality of life and survivorship for the woman over 65 become issues due to the lack of knowledge about how women over 65 view these concepts. The Healthy People 2000 Report has developed goals for a healthier society by the year 2000. The priority areas in relation to cancer include reduction in cigarette smoking, dietary changes, greater utilization of early detection mechanisms, and decreasing exposure to occupational and environmental carcinogens. Implementation of these goals should affect future generations in terms of healthy aging: however, specific programs do need to focus on the woman over 65 and her present needs which will impact current and future health status.

    This paper reports a retrospective study of the frequency, severity, modalities and mental health consequences of torture in 28 Latin American refugee women in Toronto. The data on these women and a comparison group of male torture victims were retrieved from case records in a hospital outpatient clinic. The results support the hypotheses implicit in the scanty literature available that the frequency and effects of torture in women differ from those found in men. In female victims, as in their male counterparts, the severity of the torture was related to the degree of their political involvement. However, torture was more frequently sexual, and its consequences more often affected the women's sexual adaptation. PMID:2317742

    1994-01-01

    Sex and sexuality, as well as cultural traditions, can be very sensitive areas for health workers. In Zimbabwe, as in many other societies, it is unacceptable to discuss sex publicly. However, women can and do gather together to discuss sex. The Women's Action Group (WAG), a grassroots organization working with women from both rural and urban Zimbabwe, initiated the Women's Health Information Project, which aimed to work with women to research their health needs and to implement ways of improving their health. WAG conducted a health information needs assessment through thirteen workshops across Zimbabwe, involving women from different backgrounds. Women were asked about their health problems and how their health could be improved; what traditional practices had positive or negative effects on their health; and what areas they needed more information on. These workshops enabled WAG to tackle sensitive issues, such as sexual practices, STDs, reproductive health and related cancers. During the workshops, it was discovered that women lacked information on sexual health. As a result, WAG produced a series of self-help booklets entitled "Getting to know our bodies" with the purpose of enabling women to understand, prevent, and cope with conditions that affect their bodies and to appreciate conditions that might affect them and their partners. WAG has since conducted follow-up workshops to help women use the booklets and to find further ways in improving their sexual health. PMID:12222416

    Older Hispanic Americans are a rapidly growing minority group who are disproportionately affected by diabetes mellitus and obesity. Given the importance of physical activity, particularly leisure-time activity, in the management of diabetes mellitus and obesity, the current study examined ethnic and sex differences in walking for transportation, leisure-time walking, moderate activity (not including walking), and vigorous activity between Hispanic and non-Hispanic white (NHW) older adults (age 55 and older) using the 2009 California Health Interview Survey, a population-based survey representative of California's noninstitutionalized population. The total sample consisted of 21,702 participants (20,148 NHW (7,968 men, 12,180 women) and 1,554 Hispanic (609 men, 945 women)). Multivariable logistic and linear regression analyses were adjusted for sociodemographic characteristics. The findings revealed that Hispanic men and women were significantly less likely to engage in self-reported leisure-time walking and vigorous activity than NHW men (adjusted odds ratio (aOR) = 0.71, 95% confidence interval (CI) = 0.51-0.99) and women (aOR = 0.60, 95% CI = 0.42-0.87). Regardless of ethnic group, men were more likely than women to engage in self-reported walking for transportation (aOR = 0.71, 95% CI = 0.58-0.87), moderate activity (aOR = 0.68, 95% CI = 0.57-0.81), and vigorous activity (aOR = 0.58, 95% CI = 0.50-0.68). All types of self-reported physical activity were associated with lower body mass index (BMI; P < .001), although significant interactions between sex and leisure time walking (P < .001), moderate activity (P < .001), and vigorous activity (P < .001) indicated that women who engaged in these activities reported the lowest BMIs. The findings highlight the importance of emphasizing walking in efforts to increase moderate and vigorous activity, particularly for older women. PMID:26416708

    Women continue to bear a disproportionate burden of the HIV epidemic's impact. The last three years have witnessed the explosive emergence of pre-exposure prophylaxis as a viable, woman-initiated, and woman-controlled candidate for the primary prevention of HIV in women. These developments have proven particularly significant for at-risk women in environments where negotiation of safe sex is difficult.

    Objectives To characterise pregnancy course and outcomes in women with arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). Methods From a combined Johns Hopkins/Dutch ARVD/C registry, we identified 26 women affected with ARVD/C (by 2010 Task Force Criteria) during 39 singleton pregnancies >13 weeks (1–4 per woman). Cardiac symptoms, treatment and episodes of sustained ventricular arrhythmias (VAs) and heart failure (HF) ≥ Class C were characterised. Obstetric outcomes were ascertained. Incidence of VA and HF were compared with rates in the non-pregnant state. Long-term disease course was compared with 117 childbearing-aged female patients with ARVD/C who had not experienced pregnancy with ARVD/C. Results Treatment during pregnancy (n=39) included β blockers (n=16), antiarrhythmics (n=6), diuretics (n=3) and implantable cardioverter defibrillators (ICDs) (n=28). In five pregnancies (13%), a single VA occurred, including two ICD-terminated events. Arrhythmias occurred disproportionately in probands without VA history (p=0.045). HF, managed on an outpatient basis, developed in two pregnancies (5%) in women with pre-existing overt biventricular or isolated right ventricular disease. All infants were live-born without major obstetric complications. Caesarean sections (n=11, 28%) had obstetric indications, except one (HF). β Blocker therapy was associated with lower birth weight (3.1±0.48 kg vs 3.7±0.57 kg; p=0.002). During follow-up children remained healthy (median 3.4 years), and mothers were without cardiac mortality or transplant. Neither VA nor HF incidence was significantly increased during pregnancy. ARVD/C course (mean 6.5±5.6 years) did not differ based on pregnancy history. Conclusions While most pregnancies in patients with ARVD/C were tolerated well, 13% were complicated by VA and 5% by HF.

    BACKGROUND: Colorectal cancer (CRC) is the second leading cause of cancer related deaths in the United States. Underrepresented minorities suffer disproportionately from CRC largely because of disparities in CRC screening rates, particularly by endoscopic methods. This study evaluates the association between socioeconomic, medical and psychosocial factors and the use of endoscopy in low-income minority women. METHODS: The participants were recruited from community health fairs, tenant association meetings, senior centers and local medical clinics. A survey instrument was administered to the minority women. RESULTS: Eighty-one women age >50 were included in this analysis (44 African Americans and 37 Hispanics). The two ethnic groups were demographically similar. The factors associated with having had endoscopy were language spoken (English versus Spanish), physician recommendation, cancer cons and decisional balance (difference between cancer cons and cancer pros). When endoscopy was modeled as a function of decisional balance and language spoken, only decisional balance was a significant predictor of endoscopy. CONCLUSIONS: Physician recommendation and decisional balance have a tremendous influence on whether minority women undergo endoscopy. These data suggest that if physicians increase their communication with patients regarding the benefits of screening and address patients concerns, adherence with endoscopic CRC screening can be improved in minority women.

    Developing countries are disproportionately affected by hypertension, with Black women being at greater risk, possibly due to differences in body fat distribution. The objectives of this study were: (1) To examine how different measures of body composition are associated with blood pressure (BP) and incident hypertension; (2) to determine the association between baseline or change in body composition, and hypertension; and (3) to determine which body composition measure best predicts hypertension in Black South African women. The sample comprised 478 non-hypertensive women, aged 29–53 years. Body fat and BP were assessed at baseline and 8.3 years later. Body composition was assessed using dual-energy X-ray absorptiometry (DXA) (n = 273) and anthropometry. Hypertension was diagnosed based on a systolic/diastolic BP ≥140/90 mmHg, or medication use at follow-up. All body composition measures increased (p<0.0001) between baseline and follow-up. SBP and DBP increased by ≥20%, resulting in a 57.1% cumulative incidence of hypertension. Both DXA- and anthropometric-derived measures of body composition were significantly associated with BP, explaining 3–5% of the variance. Baseline BP was the most important predictor of hypertension (adjusted OR: 98–123%). Measures of central adiposity were associated with greater odds (50–65%) of hypertension than total adiposity (44–45%). Only change in anthropometric-derived central fat mass predicted hypertension (adjusted OR: 32–40%). This study highlights that body composition is not a major determinant of hypertension in the sample of black African women. DXA measures of body composition do not add to hypertension prediction beyond anthropometry, which is especially relevant for African populations globally, taking into account the severely resource limited setting found in these communities.

    Introduction Women living with HIV experience a disproportionate burden of mental health issues. To date, global guidelines contain insufficient guidance on mental health support, particularly regarding perinatal care. The aim of this article is to describe the extent and impact of mental health issues as experienced by women living with HIV on their sexual and reproductive health and human rights (SRH&HR). Methods A global, mixed-methods, user-led and designed survey on SRH&HR of women living with HIV was conducted using snowball sampling, containing an optional section exploring mental health issues. Statistical quantitative data analysis included descriptive statistics, correlation and multiple linear regression analysis for the mental health responses. Thematic analysis of open free-text responses was performed for qualitative data. Results A total of 832 respondents from 94 countries participated in the online survey with 489 responses to the optional mental health section. Of the respondents, 82% reported depression symptoms and 78% rejection. One-fifth reported mental health issues before HIV diagnosis. Respondents reported experiencing a 3.5-fold higher number of mental health issues after diagnosis (8.71 vs 2.48, t[488]=23.00, p<0.001). Nearly half (n=224; 45.8%) had multiple socially disadvantaged identities (SDIs). The number of SDIs was positively correlated with experiencing mental health issues (p<0.05). Women described how mental health issues affected their ability to enjoy their right to sexual and reproductive health and to access services. These included depression, rejection and social exclusion, sleep problems, intersectional stigma, challenges with sexual and intimate relationships, substance use and sexual risk, reproductive health barriers and human rights (HR) violations. Respondents recommended that policymakers and clinicians provide psychological support and counselling, funding for peer support and interventions to challenge gender-based violence and to promote HR. Conclusions Interventions addressing intersecting stigmas and any especial impacts of diagnosis during pregnancy are required to ensure women's SRH&HR. Global policy guidelines regarding women living with HIV must incorporate mental health considerations. PMID:26643460

    Tropical parasitic diseases constitute the greatest threat to the health and socio-economic status of women as a gender and social group. There are some gender specific ways in which parasitic diseases affect women in contrast to men due to differences in exposure, occupational risk, sociocultural behavior, gender roles and practices. These parasitic diseases confer some social stigma, which affects the health seeking behavior of women. Women are therefore important in the control of these parasitic diseases and they are key agents of change, if they are included in community control programs. Women need more attention in endemic areas as a group that had been neglected. This deprived and excluded group have got vital role to play, as discussed in this review. PMID:18354939

    Beginning in the mid-1800s, the American Medical Association, antiobscenity crusaders, and even women's groups supported criminalization of abortion. By 1900, it was illegal nationwide. In the late 1960s, women, physicians, and states began questioning abortion laws, since many women had unsafe, often fatal, illegal abortions. By 1973, 4 states had legalized abortion and 15 other states had liberalized abortion laws. A mid-1960 study showed that private patients comprised about 95% of all elective abortions. Poor clinic patients did not have the power to convince 3 physicians to support their request for an abortion. IN 1965, the Supreme Court agreed that a Connecticut Planned Parenthood Affiliate had the right to distribute contraceptives. The 1973 Roe v. Wade Court decision advanced this decision, by confirming a woman's right to abortion during the first 2 semesters of pregnancy. In 1976, the US Congress passed the Hyde amendment forbidding federal funding (e.g., Medicaid) for abortions except to save a mother. 2 1980 Supreme Court decisions supported the Hyde amendment. The Hyde amendment and these court decisions showed discrimination against poor women. Since then there have been other decisions that have whittled away at Roe v. Wade. Contraceptive failure is responsible for about 50% of the 1.6 million abortions/year. About 60% of women having an abortion are under 25 years old. Thus, criminalization of abortion would adversely affect many women as well as society. Many prochoice physicians had cared for women who suffered from botched abortions. Physicians under 45 years old tend to not know how to perform a 2nd trimester abortion because most obstetrician/gynecology residency training programs do not require them to learn it, and they do not want to do them. 2nd trimester abortion should be a required part of residency training. Physicians as preservers of women's health should be advocating safe abortion and not adopt the legal vs. illegal abortion dichotomy. PMID:8333437

  15. Personalized Weight Management Interventions for Cardiovascular Risk Reduction: A Viable Option for African-American Women.

    2016-01-01

    Obesity is an independent contributor to cardiovascular disease (CVD) and a major driving force behind racial/ethnic and gender disparities in risk. Due to a multitude of interrelating factors (i.e., personal, social, cultural, economic and environmental), African-American (AA) women are disproportionately obese and twice as likely to succumb to CVD, yet they are significantly underrepresented in behavioral weight management interventions. In this selective review we highlight components of the limited interventions shown to enhance weight loss outcomes in this population and make a case for leveraging Web-based technology and artificial intelligence techniques to deliver personalized programs aimed at obesity treatment and CVD risk reduction. Although many of the approaches discussed are generally applicable across populations burdened by disparate rates of obesity and CVD, we specifically focus on AA women due to the disproportionate impact of these non-communicable diseases and the general paucity of interventions targeted to this high-risk group.

  20. "We will not rest." Filipino women want a fertility management program that respects women's dignity, women's bodies and women's choices.

    1993-03-01

    The program officer for the Institute for Social Studies and Action presents 1) her views on women's fertility management under different political administrations in the Philippines, 2) the political postures of influential groups, 3) the goals of women's and health groups, and 4) the actions taken by Filipino women. Under Ferdinand Marcos, the official family planning (FP) program emphasized reduction of population growth and established a quota system and incentives for the number of new acceptors. Women, as a result, became victims; e.g. IUDs were inserted without prior knowledge, and inadequate information and follow-up were provided on oral contraceptive use. Efforts were criticized for treating women as program targets and not as individuals capable of making choices. Under Corazon Aquino, the Roman Catholic hierarchy dominated and would have banned all forms of artificial contraception had women's and health groups not blocked the effort. Only in 1989 did President Aquino finally announce that multiple methods of family planning (FP) would be promoted. There was a transition in program services during the transfer to the Department of Health. Currently the government promotes FP within the safe motherhood and child survival context, but adolescents and unmarried women and couples are excluded from FP services. Population control advocates believe FP is a health issue. The Roman Catholic Church accepts only natural methods and believes artificial methods interfere with the natural processes of procreation. Anti-FP groups promote only natural FP methods and wage campaigns to discredit contraceptive methods. Women's and FP groups contend that it is a woman's right to regulate her own fertility. Safe abortion should be made available to those who need it. Women's networks are mobilizing to talk about the issues, to hold public activities to change laws and policies and to encourage women's involvement in decision making affecting their lives, and to conduct research specific to women's views. Women's organizations will be active until safe, affordable, accessible, and appropriate fertility management is available to all women. PMID:12286371

  1. UN study reports Asian economic crisis has hit women's health.

    1999-02-13

    A UN Population Fund report, "Southeast Asian Populations in Crisis," revealed that the economic crisis in Southeastern Asia has had a disproportionately adverse effect on the health of women and girls. This has occurred because the industries employing women have been hardest hit and because governments have reduced spending on health care and female education. Thailand, for example, has reduced its AIDS budget by 25% even as increasing numbers of women are pushed into the sex trade by economic necessity. Reproductive health services for adolescents have been hit just as shrinking family budgets are forcing adolescents to drop out of school. The report's authors are calling for a more detailed look at the situation. PMID:9974452

    Background Mammography is essential for early detection of breast cancer and both reduced morbidity and increased survival among breast cancer victims. Utilization is lower than national guidelines, and evidence of a recent decline in mammography use has sparked concern. We demonstrate that regression models estimated over pooled samples of heterogeneous states may provide misleading information regarding predictors of health care utilization and that comprehensive cancer control efforts should focus on understanding these differences and underlying causal factors. Our study population includes all women over age 64 with breast cancer in the Surveillance Epidemiology and End Results (SEER) cancer registries, linked to a nationally representative 5% reference sample of Medicare-eligible women located in 11 states that span all census regions and are heterogeneous in racial and ethnic mix. Combining women with and without cancer in the sample allows assessment of previous cancer diagnosis on propensity to use mammography. Our conceptual model recognizes the interplay between individual, social, cultural, and physical environments along the pathways to health care utilization, while delineating local and more distant levels of influence among contextual variables. In regression modeling, we assess individual-level effects, direct effects of contextual factors, and interaction effects between individual and contextual factors. Results Pooling all women across states leads to quite different conclusions than state-specific models. Commuter intensity, community acculturation, and community elderly impoverishment have significant direct impacts on mammography use which vary across states. Minorities living in isolated enclaves with others of the same race/ethnicity may be either advantaged or disadvantaged, depending upon the place studied. Conclusion Careful analysis of place-specific context is essential for understanding differences across communities stemming from different causal factors. Optimal policy interventions to change behavior (improve screening rates) will be as heterogeneous as local community characteristics, so no "one size fits all" policy can improve population health. Probability modeling with correction for clustering of individuals within multilevel contexts can reveal important differences from place to place and identify key factors to inform targeting of specific communities for further study.

  8. Relative anterior spinal overgrowth in adolescent idiopathic scoliosis--result of disproportionate endochondral-membranous bone growth? Summary of an electronic focus group debate of the IBSE.

    There is no generally accepted scientific theory for the etiology of adolescent idiopathic scoliosis (AIS). As part of its mission to widen understanding of scoliosis etiology, the International Federated Body on Scoliosis Etiology (IBSE) introduced the electronic focus group (EFG) as a means of increasing debate on knowledge of important topics. This has been designated as an on-line Delphi discussion. The text for this EFG was written by Professor Jack Cheng and his colleagues who used whole spine magnetic resonance imaging (MRI) to re-investigate the relative anterior spinal overgrowth of progressive AIS in a cross-sectional study. The text is drawn from research carried out with his co-workers including measurement of the height of vertebral components anteriorly (vertebral body) and posteriorly (pedicles) in girls with AIS and in normal subjects. The findings confirm previous anatomical studies and support the consensus view that in patients with thoracic AIS there is relatively faster growth of anterior and slower growth of posterior elements of thoracic vertebrae. The disproportionate anteroposterior vertebral size is associated with severity of the scoliotic curves. In interpreting the findings they consider the Roth/Porter hypothesis of uncoupled neuro-osseous growth in the spine but point out that knowledge of normal vertebral growth supports the view that the scoliosis deformity in AIS is related to longitudinal vertebral body growth rather than growth of the canal. In the mechanical mechanism (pathomechanism) they implicitly adopt the concept of primary skeletal change as it affects the sagittal plane of the spine with anterior increments and posterior decrements of vertebral growth and, in the biological mechanism (pathogenesis) propose a novel histogenetic hypothesis of uncoupled endochondral-membranous bone formation. The latter is viewed as part of an 'intrinsic abnormality of skeletal growth in patients with AIS which may be genetic'. The hypothesis that AIS girls have intrinsic anomalies (not abnormalities) of skeletal growth related to curve progression and involving genetic and/or environmental factors acting in early life is not original. While the findings of Professor Cheng and his colleagues have added MRI data to the field of relative anterior spinal overgrowth in AIS their interpretation engenders controversy. Three new hypotheses are proposed to interpret their findings: (1) hypoplasia of articular processes as a risk factor for AIS; (2) selection from the normal population to AIS involves anomalous vertebral morphology and soft tissue factors--this hypothesis may also apply to certain types of secondary scoliosis; and (3) a new method to predict the natural history of AIS curves by evaluating cerebro-spinal fluid (CSF) motion at the cranio-cervical junction. What is not controversial is the need for whole spine MRI research on subjects with non-idiopathic scoliosis. PMID:16133084

    Young immigrant women in the Netherlands demonstrate disproportionate rates of suicidal behavior. This study investigated the origins of suicidal behavior in South Asian-Surinamese, Turkish, and Moroccan immigrant young women in order to identify ethnic- and gender-specific patterns of suicidal behavior. Based on life story interviews of women who had been enrolled in mental health care, we constructed five typical patterns in which social, cultural, and personal factors were interconnected. Suicidal behavior was influenced by the ability and right to act autonomously with regard to strategic life choices, as well as by the questioning of cultural values of self-sacrifice and protection of honor.

    Restrictions on the use of federal funds to provide abortions have limited the access to abortion services for Native American women receiving care at Indian Health Service facilities. Current data suggest that the vast majority of Indian Health Service facilities are unequipped to provide abortions under any circumstances. Native American women experience disproportionately high rates of sexual assault and unintended pregnancy. Hyde Amendment restrictions systematically infringe on the reproductive rights of Native American women and present a pressing public health policy concern. PMID:25122025

    1993-02-01

    In developing countries, all development activities as well as reclamation of degraded areas, pollution reduction, and preservation of biodiversity affect women's environment, especially in rural areas. Women produce most subsistence foods and cash crops, but control only about 1% of the world's land. Lack of land tenure and of access to it keep women from obtaining credit, training, and other supports, thereby preventing them from using their traditional, longterm conservation practices. In many developing countries, commercial producers force women off the most productive lands and onto marginal lands where they grow subsistence crops. They tend to overuse the marginal land and to allow little time for soil recovery. Soil degradation is exacerbated when women need to travel greater distances to collect fuelwood, water, fodder, and food. Almost complete desertification awaits Rajasthan, India, where such events and intensive cash cropping occur. Heavy pesticide use on large commercial farms increases pest resistance, thereby boosting infestation and reducing species diversity. Women are testing sustainable agricultural techniques, for instance, interplanting and crop rotation. Even though women supply water needs, they tend to be excluded from planning, implementing, and maintaining water supplies. Women depend on forests to provide food, fodder, fuel, building materials, medicines, and many materials for income-earning efforts. Commercial logging, migration and resettlement, agricultural development, and cutting for firewood and charcoal destroy these forests. Reforestation schemes do not consider women's needs. Deforestation and desertification increase women's work burdens. Poor women who have migrated to urban areas also experience environmental degradation, deteriorating health, and resource depletion; most live in squatter settlements. Deteriorating economic circumstances in developing countries, reduced flows of official development assistance to developing countries, rapid population growth, lack of women's support mechanisms, and civil conflict are underlying factors for environmental degradation.

    Women still treated as 2nd class citizens in many developing countries despite international initiatives such as the UN convention on elimination of all forms of discrimination against women that was ratified by 105 countries. The disadvantages that confront women have social repercussions because women play a central role in the development process, especially in deciding the size of their families, and also in administering environmental resources. Efforts of women to improve their families' conditions involve then in management of such natural resources as soil, forests, and water, and also involve then in management of the household potable water supply and waste disposal. In some parts of sub-Saharan Africa, up to 70% of food production, processing, and marketing is in the hands of women. Women in many countries have the task of gathering firewood, which can require 5-10 hours of work several times a week in areas where firewood has become scarce. At the same time, women are often denied the opportunity of contributing to the economic support of their household because of their childcare responsibilities. A woman's prestige in some cultures is defined by her capacity to have many children. Lack of education and employment often prompt women to marry young and have many children, especially in countries where children contribute to family income. Local administration of natural resources improves when women become part of the development process. It is urgent that women's status be improved through social and political changes enabling them to make decisions affecting their own lives, such as postponing marriage and having the number of children they want. Family planning services should be available, and motivation for smaller families should be reinforced through better health care and educational and employment opportunities for women.

    2014-08-01

    Most male professionals have more experience mentoring men than they do mentoring women, and their male mentees progress further than their female mentees. Yet, in academic medicine, men have few forums in which to discuss the gender-related issues that they encounter. To address the gender-related questions that commonly arise, the author of this commentary offers perspectives and recommendations, consolidated from over 25 years of experience leading career and talent development programs, to assist men in successfully mentoring women. Her recommendations are organized around three questions: (1) How do women's and men's experiences in mentoring relationships tend to differ? (2) What interferes with the accurate evaluation of women's skills? and (3) Is the current generation of female trainees still at a gender-related disadvantage? She argues that men's ability to effectively mentor women depends to a great extent on their understanding of the challenges that women disproportionately face in developing their careers. Mentors who are skilled in adapting to the gender-related needs of mentees will contribute to women's retention and development in academic medicine, enhance the leadership capacity of their organizations and the profession, and extend their own legacies.

    2016-03-01

    Abdominal aortic aneurysm (AAA) has long been recognized as a condition predominantly affecting males, with sex-associated differences described for almost every aspect of the disease from pathophysiology and epidemiology to morbidity and mortality. Women are generally spared from AAA formation by the immunomodulating effects of estrogen, but once they develop, the natural history of AAAs in women appears to be more aggressive, with more rapid expansion, a higher tendency to rupture at smaller diameters, and higher mortality following rupture. However, simply repairing AAAs at smaller diameters in women is a debatable solution, as even elective endovascular AAA repair is fraught with higher morbidity and mortality in women compared to men. The goal of this review is to summarize what is currently known about the effect of gender on AAA presentation, treatment, and outcomes. Additionally, we aim to review current controversies over screening recommendations and threshold for repair in women. PMID:26747679

    2007-01-01

    This study uses Kraemer's approach for nonrandom comorbidity to identify the parameters of revictimization among women, using a diverse, population-based sample. Participants (n = 11,056) are from the California Women's Health Survey. Women were asked about childhood and adult violence and current symptoms of posttraumatic stress disorder (PTSD), depression, and anxiety. Logistic regressions adjusted for age, ethnicity, education, and poverty indicate that women who experienced childhood physical or sexual abuse were 5.8 (95% confidence interval, 5.2-6.4) times more likely to experience adult physical or sexual victimization. Revictimization affected 12% of women, and these women were substantially more likely to report current symptoms of anxiety, depression, and PTSD than women exposed to violence only in childhood or only as an adult. Revictimization is a methodologically distinct concept and is a potent risk factor for adult mental health problems. Prevention should target women exposed to both physical and sexual assault.
