Project description:ObjectiveTo assess whether editorial desk rejection at general medical journals (without peer review) of two clinical research manuscripts may relate to author gender or women's physiology topics. Given evidence for bias related to women in science and medicine, and editorial board attitudes, our hypothesis was that submissions by women authors, on women's reproductive, non-disease topics received differential editorial assessment.DesignA prospective investigation of publications, author gender and topics in general medical journals in two issues following the editorial rejections of two clinical research manuscripts by five major English-language general medical journals. The rejected manuscripts (subsequently published in lower impact journals) described research funded by national granting bodies, in population-based samples, authored by well-published women scientists at accredited institutions and describing innovative women's reproductive physiology results.SettingTertiary academic medical centre.Main outcome measuresAll clinical research published in the two issues following rejection date by each of the five major general medical journals were examined for first/senior author gender. The publication topic was assessed for its gendered population relevance, whether disease or physiology focused, and its funding. Rejection letters assessed editor gender and status.ResultsWomen were underrepresented as original research authors; men were 84% of senior and 69% of first authors. There were no, non-disease focused publications relating to women's health, although most topics were relevant to both genders. The majority (80%) of rejection letters appeared to be written by junior-ranked women editors.ConclusionSex/gender accountability is necessary for clinical research-based editorial decisions by major general medical journals. Suggestions to improve gender equity in general medical journal publication: (1) an editorial board sex/gender champion with power to advocate for manuscripts that are well-performed research of relevance to women's health/physiology; (2) an editorial rejection adjudication committee to review author challenges; and (3) gender parity in double-blind peer review.

Project description:Investment in the production of transmissible stages (gametocytes) and their sex ratio are malaria parasite traits that underpin mosquito infectivity and are therefore central to epidemiology. Malaria parasites adjust their levels of investment into gametocytes and sex ratio in response to changes in the in-host environment (including red blood cell resource availability, host immune responses, competition from con-specific genotypes in mixed infections, and drug treatment). This plasticity appears to be adaptive (strategic) because parasites prioritize investment (in sexual versus asexual stages and male versus female stages) in manners predicted to maximize fitness. However, the information, or 'cues' that parasites use to detect environmental changes and make appropriate decisions about investment into gametocytes and their sex ratio are unknown.Single genotype Plasmodium chabaudi infections were exposed to 'cue' treatments consisting of intact or lysed uninfected red blood cells, lysed parasitized RBCs of the same clone or an unrelated clone, and an unmanipulated control. Infection dynamics (proportion of reticulocytes, red blood cell and asexual stage parasite densities) were monitored, and changes in gametocyte investment and sex ratio in response to cue treatments, applied either pre- or post-peak of infection were examined.A significant reduction in gametocyte density was observed in response to the presence of lysed parasite material and a borderline significant increase in sex ratio (proportion of male gametocytes) upon exposure to lysed red blood cells (both uninfected and infected) was observed. Furthermore, the changes in gametocyte density and sex ratio in response to these cues depend on the age of infection. Demonstrating that variation in gametocyte investment and sex ratio observed during infections are a result of parasite strategies (rather than the footprint of host physiology), provides a foundation to investigate the fitness consequences of plasticity and explore whether drugs could be developed to trick parasites into making suboptimal decisions.

Project description:BackgroundWomen in Mozambique are often disempowered when it comes to making decisions concerning their lives, including their bodies and reproductive options. This study aimed to explore the views of women in Mozambique about key elements of empowerment for reproductive decisions and the meanings they attach to these elements.MethodsQualitative in-depth interviews were undertaken with 64 women of reproductive age (18-49 years) in two provinces in Mozambique. Participants were recruited through convenience sampling. Data collection took place between February and March 2020 in Maputo city and Province, and during August 2020 in Nampula Province. A thematic analysis was performed.ResultsWomen described crucial elements of how power is exerted for reproductive choices. These choices include the ability to plan the number and timing of pregnancies and the ability either to negotiate with sexual partners by voicing choice and influencing decisions, or to exercise their right to make decisions independently. They considered that women with empowerment had characteristics such as independence, active participation and being free. These characteristics are recognized key enablers for the process of women's empowerment.ConclusionsThis study's findings contribute to an expanded conceptualization and operationalization of women's sexual and reproductive empowerment by unveiling key elements that need to be considered in future research and approaches to women's empowerment. Furthermore, it gave women the central role and voice in the research of empowerment's conceptualization and measurement where women's views and meanings are seldom considered.

Project description:Tobacco and alcohol use by adolescents are major public health concerns in South Africa. However, the extent to which key psychosocial risk factors for tobacco use and alcohol use by adolescents in South Africa are shared or unshared is unclear. This study sought to examine the shared and unshared risk factors for tobacco and alcohol use among adolescents in Johannesburg.Participants comprised 736 males and females aged 12-17 years who were recruited via a household survey conducted during 2004. The participants were interviewed using a questionnaire comprising measures of personal, family (parental bonding and family legal drug use) and contextual (school and neighbourhood) factors. Separate multiple logistic regression analyses were conducted to predict lifetime alcohol use and lifetime tobacco use from variables within each domain (personal, family and contextual), controlling for demographic factors.Personal, family (parental bonding) and contextual factors (school factors) were primarily shared risk factors for tobacco and alcohol use, while family legal drug use and neighbourhood factors were largely unshared.Interventions addressing personal, parenting and schooling factors are likely to have an impact on preventing both tobacco and alcohol use, whereas interventions focused on ameliorating family drug use and neighbourhood factors may need to be more substance-specific.

Project description:Real-life decisions are often repeated. Whether considering taking a job in a new city, or doing something mundane like checking if the stove is off, decisions are frequently revisited even if no new information is available. This mode of behavior takes a particularly pathological form in obsessive-compulsive disorder (OCD), which is marked by individuals' redeliberating previously resolved decisions. Surprisingly, little is known about how information is transferred across decision episodes in such circumstances, and whether and how such transfer varies in OCD. In two experiments, data from a repeated decision-making task and computational modeling revealed that both implicit and explicit memories of previous decisions affected subsequent decisions by biasing the rate of evidence integration. Further, we replicated previous work demonstrating impairments in baseline decision-making as a function of self-reported OCD symptoms, and found that information transfer effects specifically due to implicit memory were reduced, offering computational insight into checking behavior.

Project description:This paper discusses patterns of daily smokeless tobacco (SLT) use and correlates of poly SLT use among married women aged 18-40 years in a Mumbai slum community with implications for tobacco control.Using a mixed methods approach, the study included a structured survey with 409 daily SLT users and in-depth interviews with 42 women. Participants for the survey were selected using a systematic sampling procedure (one woman in every fourth eligible household). Univariate and bivariate analysis, and multiple logistic regressions were conducted to identify demographic and social factors associated with women's use of poly SLT products. To illustrate survey results, in-depth interviews were analyzed using Atlas ti software.Sixty-four percent of the women surveyed used only one type of SLT; of these, 30% used mishri, 32% used pan with tobacco and the rest used chewed tobacco (11%), gul (17%) or gutkha (10%). Thirty-six percent used more than one type of SLT. Poly SLT users chewed or rubbed 50% more tobacco as compared to single users (mean consumption of tobacco per day: 9.54 vs. 6.49 grams; p<0.001). Women were more likely to be poly SLT users if they were illiterate as compared to literate (adjusted odds ratio [AOR]=1.67; 95% confidence interval [CI]=1.07-2.71), if they had lived in Mumbai for 10 years or more, versus less than ten years (AOR=1.67, 95% CI=1.03-2.71); and if their husband was a poly SLT user as compared to a non SLT user (AOR=2.78, 95% CI=1.63-4.76). No differences were noted between pregnant and non-pregnant women in SLT consumption patterns.Tobacco control policies and programs must focus specifically on both social context and use patterns to address SLT use among women of reproductive age with special attention to poly SLT users, an understudied and vulnerable population.

Project description:Decisions often reflect implicit biases. Ethnic, racial, and gender traits are associated with stereotypes that may influence the decision-making process. Previous research shows that referees' decisions in men's professional sports are often biased in favor of racial and nationalistic in-groups. This study examined if similar biases exist in women's professional sports. Additionally, this study analyzed the potential influence of the gender composition of referee teams on rapid decisions. We gathered data on referee foul calls in women's professional basketball in Spain, 2014-2019 and defined important decisions (fifth fouls) and stressful situations (one-possession matches). The main finding is that out-groups based on racial (i.e., Black players) and nationalistic (i.e., foreign players) criteria did not differ in number of foul calls received. In stressful situations, foreign players actually received fewer fouls than Spanish players. Similarly, there was no evidence of bias due to the gender composition of referee teams: foul calls did not differ between all-male and mixed teams. Implications for race and nationality as dynamic social constructs within ethnocentric and social identity theories are discussed.

Project description:To predict differentially expressed miRNAs between monosomy 3 and disomy 3, and to associate these miRNAs with the clinico-pathological parameters in South Asian Indian population with uveal melanoma (UM). The study consists of six uveal melanoma primary tumour tissues of South Asian-Indian population. These six tumours have been screened for chromosome 3 aberration using Chromogenic in-situ hybridisation (CISH). Thus, sample under the study includes, three each of monosomy 3 and disomy 3. The miRNA profiling was carried out from the tumor sections of formalin-fixed paraffin embedded eyeball samples. miRNA expression profile was obtained in monosomy 3 and disomy 3 samples, analysed by unsupervised analysis (Principal Component Analysis) and supervised analysis (Significance analysis of microarray). The select up-regulated and candidate miRNAs associated with monosomy 3 uveal melanoma tumors were validated further with qRT-PCR (n=86). Thus, this study indicates the role of miRNAs in UM tumor progression and their implication in predetermining the liver metastasis.

Project description:This paper explores reproductive decision-making among young women in South Africa's informal settlements and considers whether and how agency and social norm theory inform their decisions. Understanding whether, when and how young women make decisions about conception and motherhood is critical for supporting women to avoid unplanned, early motherhood. Qualitative data were collected from 15 young women in informal settlements in eThekwini, South Africa at three time points over 18 months, using in-depth interviews, participant observation and photovoice, and were analysed inductively. When the young women were teenagers and into their early twenties, and had not yet had a child, most paid little attention to whether or not they conceived. This shifted as they grew older and/or after having a first child, at which point many of the women began to express, and sometimes act upon, a greater desire to control whether and when they conceived and delay further pregnancies. At different times in their lives, both social norms and reproductive agency, specifically 'distributed agency' played significant roles in influencing their reproductive decision-making. Social norms held the most influence when they were teenagers and experiencing normative pressures to have a baby while young. As they grew older and/or had a first child they began to assert some agentic control around their reproduction. We therefore recommend that in order to improve the effectiveness of services and interventions supporting young women to delay unplanned pregnancies, programmers, researchers and policy makers must develop a better understanding of the role of social norms and agency at different stages of women's lives.

Project description:Effective agricultural extension is key to improving productivity, increasing farmers' access to information, and promoting more diverse sets of crops and improved methods of cultivation. In India, however, the coverage of agricultural extension workers and the relevance of extension advice is poor. We investigate whether a women's self-help group (SHG) platform could be an effective way of improving access to information, women's empowerment in agriculture, agricultural practices, and production diversity. We use cross-sectional data on close to 1,000 women from five states in India and employ nearest-neighbor matching models to match SHG and non-SHG women along a range of observed characteristics. We find that participation in an SHG increases women's access to information and their participation in some agricultural decisions, but has limited impact on agricultural practices or outcomes, possibly due to financial constraints, social norms, and women's domestic responsibilities. SHGs need to go beyond provision of information to changing the dynamics around women's participation in agriculture to effectively translate knowledge into practice.
