    The general population is exposed to bisphenol A (BPA) orally, parenterally, transdermally, and environmentally as a result of the use of BPA in food packaging, plastics, and personal care products. The majority of the population nowadays (91-99%) has detectable levels of BPA inside their body. In this study, we successfully performed an inexpensive, rapid, and simple protein precipitation procedure for extraction of BPA from human plasma, followed by analysis by LC-MS/MS. This method was specifically developed for handling large numbers of samples with minimum cost and volume of sample. The developed method was accurate, precise, and reproducible for quantification of BPA from human plasma samples in the concentration range of 10-2000 ng/mL. The method was performed on samples from 150 healthy volunteers who were enrolled in the study. The mean of observed BPA level was 2.22 ± 9.91 ng/mL. Higher BPA levels were observed for females compare to that of males (p-value = 0.002), the BPA levels were higher in participants 33 years of age and older compared to those less than 33 years of age (p-value = 0.000), then the BPA levels higher in subjects with tap water as source of drinking (p-value = 0.005). This method may be valuable for general risk assessment of BPA for a large and varied population because of its efficiency and economical aspects.

    BACKGROUND AND PURPOSE: Women's representation in medicine has increased over time yet the proportion of women practicing neurointervention remains low. We conducted an anonymous online survey through which we could explore the gender gap in neurointervention, identify potential issues, difficulties, or obstacles women might face, and evaluate if men encounter similar issues.

    METHODS: An online questionnaire was designed in SurveyMonkey®. Invitation to participate was emailed through national and international neurointerventional societies as well as directly through private mailing lists to men and women working in neurointervention. Responses were collected from 10 May 2019 to 10 September 2019.

    RESULTS: There were 295 complete responses, 173 (59%) male and 122 (41%) female. Most respondents (83%) fell within age categories 35-60 years, with representation from 40 countries across five continents. In all 95% were working full time, 73% had worked as a neurointerventionalist for >6 years, 77% worked in University-affiliated teaching institutions. Almost half of the respondents indicated no female neurointerventionalist worked in their center. Female respondents were younger and age-adjusted analysis was undertaken. Significantly fewer females than males were married and had children. Significantly fewer females held supervisory roles, held academic titles, and significantly less had a mentor. Females were less satisfied in their careers. More females felt they receive less recognition than colleagues of the opposite sex. Males had a greater proportion of work time dedicated to neurointervention. Similar proportions of both genders experienced bullying in work (40%-47%); however, sexual harassment was more common for females. There were no differences between genders in how they dealt with complications or their effects on mental well-being.

    CONCLUSION: There are many potential reasons why women are underrepresented in neurointervention, however, the literature suggests this is not unique to our specialty. Multiple long-term strategies will be necessary to address these issues, some of which are discussed in the article.

    Previous evidence suggests males and females differ with respect to interoception-the processing of internal bodily signals-with males typically outperforming females on tasks of interoceptive accuracy. However, interpretation of existing evidence in the cardiac domain is hindered by the limitations of existing tools. In this investigation, we pooled data from several samples to examine sex differences in cardiac interoceptive accuracy on the phase adjustment task, a new measure that overcomes several limitations of the existing tools. In a sample of 266 individuals, we observed that females outperformed males, indicative of better cardiac interoceptive accuracy, but had lower confidence than males. These results held after controlling for sex differences in demographic, physiological and engagement factors. Importantly, these results were specific to the measure of cardiac interoceptive accuracy. No sex differences were observed for individuals who completed the structurally identical screener task, although a similar pattern of results was observed in relation to confidence. These surprising data suggest the presence of a female advantage for cardiac interoceptive accuracy and potential differences in interoceptive awareness (metacognition). Possible reasons for mixed results in the literature, as well as implications for theory and future research, are discussed.

    An estimated 37,000 cisgender and transgender women work as sex workers in Malaysia, a population that has been disproportionately affected by the HIV epidemic. Although Malaysia provides no-cost antiretroviral therapy (ART) to people with HIV, little is known about sex workers' engagement in the HIV care continuum. We analyzed data from 57 HIV-infected cisgender women (n = 33) and transgender women (n = 24) sex workers from a respondent-driven sampling study on HIV prevalence among sex workers in Kuala Lumpur, Malaysia. We examined the proportion of women who were newly diagnosed with HIV, had a baseline CD-4 count test, were initiated and retained on antiretroviral treatment (ART). Overall, only 26.3% had ever been HIV tested and almost 60% were newly diagnosed. Only a small proportion of cisgender (15.2%) and transgender (12.5%) women were currently taking ART. Interventions to enhance sex workers' engagement in the HIV care continuum are urgently needed. Deployment of evidence-based strategies to improve linkage and retention in HIV care should be adapted to address the unique needs of this important key population.

    The Malaysian government has committed to 'Fast Tracking the HIV Response' to achieve UNAIDS 2030 targets to end AIDS. The epidemic is concentrated among key populations and has shifted from people who inject drugs to HIV infection through sexual transmission among men who have sex with men, sex workers and transgender people. The aim of this scoping review was to examine social and behavioural research published since 2005 that can inform understanding of each stage of the 90:90:90 treatment cascade (as proposed by UNAIDS), including HIV risk behaviours and testing practices that precede entry. We found a concentration of studies related to predictors or correlates of HIV infections (mostly among men who have sex with men) and a shortfall in literature pertaining to sex workers or transgender people. While several studies examined factors associated with HIV testing, only one examined uptake of antiretroviral therapy and two explored issues of treatment adherence. No study examined broader care and support of people living with HIV. To scale-up effective programmes and apprise investment to achieve the ambitious targets set-out in the Malaysian National HIV/AIDS Strategic Plan, a combination of comprehensive strategic information and evidence generated through primary research is critical.

    This article presents the Islamic bioethical deliberation on the issue of sex assignment surgery (SAS) for infants with disorders of sex development (DSD) or intersexed as a case study. The main objective of this study is to present a different approach in assessing a biomedical issue within the medium of the Maqasid al-Shari'ah. Within the framework of the maqasidic scheme of benefits and harms, any practice where benefits are substantial is considered permissible, while those promoting harms are prohibited. The concept of Maqasid al-Shari'ah which is the mechanistic interpretation of Qur'an and Hadith presents the holistic attention of Islam on many life activities, including healthcare. Indeed, this concept encompasses many aspects of worldly life, both for the human individual and collectively for the whole society. In healthcare, the practice of SAS on DSD newborns has presented an assortment of implications on the future livelihood of the affected individual. The process of decision-making seems to be very multifaceted since every element such as the determination of the 'correct' sex and the urgency of early surgery must consider the benefits and harms, as well as the child's rights and best interest. The application of the concept of Maqasid al-Shari'ah, would convey a pragmatic approach that is often disregarded in Western medicine. This approach considers the right of the individual to live life optimally, individually and socially and practice his faith, precisely, in accordance with the assigned gender.

    The genera Parandrocephalus Heller, 1916 and Hexamitodera Heller, 1896 are reviewed and redescribed. Based on the combination of chromatic sexual dimorphism, velvety pubescence on the whole dorsal body and distinctly developed carina on the elytra, Parandrocephalus blairi Bentanachs & Vives, 2009 is transferred to Hexamitodera. A new subgenus, Sulcognatha Perger, is instituted to accommodate mandible, head and metasternal modifications in Hexamitodera blairi comb. n. that are lacking in the type species of Hexamitodera, Hexamitodera semivelutina. As indicated by fundamental structural differences in the mandibles of Parandrocephalus and Hexamitodera (Sulcognatha) blairi comb. n., the exaggerated secondary sexual traits and open procoxal cavities in both taxa are presumably the result of convergent evolution. Contrary to Bentanachs & Vives (2009), the presence of the two Parandrocephalus species in Sundaland and the endemism of Hexamitodera on Sulawesi agree well with the zoogeographical separation of both areas by the Wallace line.

    The white-bellied sea eagle, Haliaeetus leucogaster, displays reversed sexual size dimorphism and is monomorphic for adult plumage coloration. Early attempts to identify sex in sexually monomorphic birds were based on morphological or chromosomal characters, but since avian W-specific DNA sequences were identified, PCR amplification has become commonly used for molecular sexing. We used a PCR test employing primers that amplify two homologous fragments of both the CHD-W gene, unique to females, and the CHD-Z gene, occurring in both sexes. This test was applied to five individuals of H. leucogaster from the Malacca Zoo and to male and female domestic chickens, Gallus domesticus, for comparison. All individuals were sexed successfully with high reproducibility. We conclude that this PCR-based test with feathers as the DNA source is a reliable sexing method for H. leucogaster. This sexing technique is objective and non-invasive and could be used to test sex ratio theories, as well as to help improve conservation and management actions for captive breeding program of this species in Malaysia.

    Disorders of sex development (DSD), are a group of rare congenital conditions. Unlike 46, XX DSD where the cause is usually clear, identification of a cause of XY DSD is often unclear and may be attributed to a disorder of gonadal development, androgen synthesis or androgen action. Reaching a firm diagnosis is challenging and requires expertise within a framework that abides by the highest standards of clinical care. Whilst conditions associated with altered sex development have improved our fundamental understanding of sex and gonadal development, it is debatable whether this improvement in our understanding has improved the lives of people with DSD. Thus, there is a need for more emphasis on showing that a firm diagnosis for conditions associated with DSD is associated with a change in clinical practice that benefits the patient. With the rapid advances in diagnostic technology, there is also a need for clearer guidance on the relative merits of biochemical vs genetic evaluation. The standardization and harmonization of complex genetic and biochemical analyses for rare conditions are issues that require further guidance and it is probably that international networks and registries for rare conditions will facilitate the development of this framework.

    Sexually anomalous individuals, typically intersexes or gynandromorphs, bear a mixture of male and female traits. Twelve sexually anomalous individuals of the black fly Simulium (Gomphostilbia) trangense Jitklang, Kuvangkadilok, Baimai, Takaoka & Adler were discovered among 49 adults reared from pupae. All 12 sexually anomalous adults were parasitized by mermithid nematodes, although five additional parasitized adults had no overt external anomalies. Sequence analysis of the 18S rRNA gene revealed that the mermithids, possibly representing a new species, are related to Mesomermis spp., with genetic distances of 5.09-6.87%. All 12 anomalous individuals had female phenotypical traits on the head, thorax, forelegs, midlegs, and claws, but male features on the left and right hind basitarsi. One individual had mixed male and female genitalia. The findings are in accord with the trend that mermithid infections are associated with sexually anomalous adult black flies.

    Citation: Hitchman SC, Fong GT. The Bad With the Good? The Relation Between Gender Empowerment and Female-to-Male Cigarette Smoking Rates Across 74 Countries. ITC Project Working Paper Series. University of Waterloo, Waterloo, Ontario, Canada.; 2010

    Objective: Worldwide it is estimated that men smoke at nearly five times the rate of women. However, there is wide variation across countries in the gender smoking ratio (ratio of female-to-male smoking prevalence rates). Lower smoking rates among women have been attributed to social norms against women smoking, and women’s lower social status and economic resources. We tested the hypothesis that in countries with higher gender empowerment, the gender smoking ratio would be closer to 1.
    Methods: We correlated the gender smoking ratio (calculated from the 2008 WHO Global Tobacco Control Report) and the United Nations Development Programme’s Gender Empowerment Measure (GEM). Because a country’s progression through stages of the tobacco epidemic and its gender smoking ratio has been attributed to its level of development, we also examined this relation partialling on economic development (Gross National Income (GNI) per capita), and income inequality (Gini).
    Findings: The gender smoking ratio was significantly and positively correlated with the GEM. GEM was also the strongest predictor of the gender smoking ratio when controlling for GNI per capita and Gini in a multiple regression analysis.
    Key Conclusions: The findings identify a challenge for countries undergoing economic development and greater gender equality: can such progress take place without a corresponding increase in smoking rates among women? These findings thus highlight the need for strong tobacco control in countries in which gender equality is increasing.

    BACKGROUND: Aquaporin-4 (AQP4) antibody-associated neuromyelitis optica spectrum disorder (NMOSD) is an antibody-mediated inflammatory disease of the central nervous system. We have undertaken a systematic review and meta-analysis to ascertain the sex ratio and mean age of onset for AQP4 antibody associated NMOSD. We have also explored factors that impact on these demographic data.

    METHODS: A systematic search of databases was conducted according to the PRISMA guidelines. Articles reporting sex distribution and age of onset for AQP4 antibody-associated NMSOD were reviewed. An initially inclusive approach involving exploration with regression meta-analysis was followed by an analysis of just AQP4 antibody positive cases.

    RESULTS: A total of 528 articles were screened to yield 89 articles covering 19,415 individuals from 88 population samples. The female:male sex ratio was significantly influenced by the proportion of AQP4 antibody positive cases in the samples studied (p sex ratio was 8.89 (95% CI 7.78-10.15). For paediatric populations the estimate was 5.68 (95% CI 4.01-8.03) and for late-onset cases, it was 5.48 (95% CI 4.10-7.33). The mean age of onset was significantly associated with the mean life expectancy of the population sampled (p sex ratio and the mean age of onset of AQP4 antibody-associated NMOSD are significantly higher than MS. The sex ratio increases with the proportion of cases that are positive for AQP4 antibodies and the mean age of onset increases with population life expectancy.

    INTRODUCTION: Sexual health education among individuals with autism spectrum disorder (ASD) is unique and may not be adequately addressed both at home and at school. Parents have an important role in delivering sexual health education to their children. This is a pilot study to evaluate parental awareness and effectiveness of parent sexual health training for children with ASD.

    MATERIALS AND METHODS: Parents of 30 children with ASD with ages ranging from 8 to 12 years attending Child Development Clinic, Hospital Pulau Pinang (CDC HPP) were recruited. Parents attended two-hour virtual parent sexual health training and educational materials were provided to be utilised at home. Follow-up via phone consultation were done at three and six months to ensure training was carried out. Both structured interview and Vineland adaptive behaviour scales (VABS-3) were done at recruitment and at eight months via phone consultation. Wilcoxon-signed rank test was used to analyse differences between pre- and postintervention outcome measures.

    RESULTS: Statistically significant increase in number of sexual health topics taught by parents and appropriate socio-sexual behaviours of children were found. Intellectual function of children with ASD influenced the study outcomes.

    CONCLUSION: Parent sexual health training can be done to empower parents to educate children with ASD and promote appropriate socio-sexual behaviours.

    Some diopsid flies have sexually dimorphic eye stalks that are assumed to require considerable nutrition for growth but are advantageous in competition and courtship. According to the handicap theory, the eye span in some dimorphic species serves as a reliable signal of individual quality to an opponent. However, it is not well understood how well eye span represents energy source storage. In this study, we focused on two species: Sphyracephala detrahens, which has weak dimorphism, and Cyrtodiopsis dalmanni, which has moderate dimorphism. We found that the eye stalks of the former species contained more fat bodies than those of the latter species. When the flies were starved, the fat body cells in the eye stalks underwent autophagy. A strong positive correlation was consistently found between eye span and starvation tolerance for S. detrahens, while a weak correlation was found for C. dalmanni. Furthermore, starvation decreased the contest winning rate between S. detrahens pairs with similar eye spans. These findings suggest that the presentation of resource holding potential may be larger than the actual storage ability and that the fidelity of nutritional storage signaling varies; the signal presented by S. detrahens is more reliable than that presented by C. dalmanni.

    This study examines safer sex negotiation and its association with condom use among clients of female sex workers (FSWs) in Bangladesh. Data were collected from 484 FSWs living in Dhaka city following a convenient sampling procedure. Overall, 47% of the clients were suggested to use condom during last sexual intercourse and 21% did so. Both bivariate and multivariable binary logistic regression analyses yielded significantly increased risk of negotiation for safer sex with clients among FSWs with higher education. The power bargaining significantly (P < .001) increased the risk of condom use by 2.15 times (95% confidence interval = 1.28-3.59). The odds of condom use were significantly higher among the FSWs with higher education, unmarried, hotel-based, and among those with higher level of HIV/AIDS-related knowledge. The Bangladeshi FSWs have little control over their profession. HIV prevention programs should aim to encourage FSWs through information, education, and communication program to insist on condom use among clients.

    AIM: The aim of this study was to synthesize the experiences of people with disorders of sex development.

    BACKGROUND: The quality of life of people with disorders of sex development depends largely on the availability of good psychosocial and psychosexual management. There is a lack of qualitative systematic reviews of the literature on the experiences of people with disorders of sex development.

    DESIGN: The seven steps of qualitative meta-ethnography were employed in this review.

    DATA SOURCES: The following electronic databases were systematically searched until January 2017: Science Direct, Scopus, Sage online, CINAHL, PsycINFO, Medline, Wiley Online Library, and Google Scholar. Search terms for this review were "disorders of sex development," "intersex," "ambiguous genitalia," "experiences," "qualitative study," and "method".

    REVIEW METHOD: A 13-item scale was applied to evaluate the quality of the selected studies and synthesized using the principles of meta-ethnography.

    FINDINGS: Twelve studies met the eligibility criteria. Six major themes described the experiences of people with disorders of sex development. These included a range of physical, psychological, social, and sexual experiences which affect their quality of life. Different coping strategies were employed by individuals who live with the lifelong condition.

    CONCLUSION: Disorders of sex development affect the quality of life of people living with these disorders. Nurses are tasked with providing holistic care for people with disorders of sex development in order to improve their quality of lives. As such, there is a need to explore the experiences of nurses in the management of disorders of sex development.
