“It’s for us –newcomers, LGBTQ persons, and HIV-positive persons. You feel free to be”: a qualitative study exploring social support group participation among African and Caribbean lesbian, gay, bisexual and transgender newcomers and refugees in Toronto, Canada
BACKGROUND: Stigma and discrimination harm the wellbeing of lesbian, gay, bisexual and transgender (LGBT) people and contribute to migration from contexts of sexual persecution and criminalization. Yet LGBT newcomers and refugees often face marginalization and struggles meeting the social determinants of health (SDOH) following immigration to countries such as Canada. Social isolation is a key social determinant of health that may play a significant role in shaping health disparities among LGBT newcomers and refugees. Social support may moderate the effect of stressors on mental health, reduce social isolation, and build social networks. Scant research, however, has examined social support groups targeting LGBT newcomers and refugees. The purpose of this qualitative study was to explore experiences of social support group participation among LGBT African and Caribbean newcomers and refugees in an urban Canadian city. METHODS: We conducted 3 focus groups with a venue-based sample of LGBT African and Caribbean newcomers and refugees (n = 29) who attended social support groups at an ethno-specific AIDS Service Organization. Focus groups followed a semi-structured interview guide and were analyzed using narrative thematic techniques. RESULTS: Participant narratives highlighted immigration stressors, social isolation, mental health issues, and challenges meeting the SDOH. Findings reveal multi-level benefits of social support group participation at intrapersonal (self-acceptance, improved mental health), interpersonal (reduced isolation, friendships), community (reciprocity, reduced stigma and discrimination), and structural (housing, employment, immigration, health care) levels. CONCLUSIONS: Findings suggest that social support groups tailored for LGBT African and Caribbean newcomers and refugees can address social isolation, community resilience, and enhance resource access. Health care providers can provide support groups, culturally and LGBT competent health services, and resource access to promote LGBT newcomers and refugees’ health and wellbeing
Beyond a Zero-Sum Game: How Does the Impact of COVID-19 Vary by Gender?
Epidemics and pandemics, like COVID-19, are not gender neutral. Much of the current work on gender, sex, and COVID-19, however, has seemed implicitly or explicitly to be attempting to demonstrate that either men or women have been hardest hit, treating differences between women and men as though it is not important to understand how each group is affected by the virus. This approach often leaves out the effect on gender and sexual minorities entirely. Believing that a more nuanced approach is needed now and for the future, we brought together a group of gender experts to answer the question: how are people of different genders impacted by COVID-19 and why? Individuals working in women's, men's, and LGBTQ health and wellbeing wrote sections to lay out the different ways that women, men, and gender and sexual minorities are affected by COVID-19. We demonstrate that there is not one group "most affected," but that many groups are affected, and we need to move beyond a zero-sum game and engage in ways to mutually identify and support marginalized groups
PDGF-C Induces Maturation of Blood Vessels in a Model of Glioblastoma and Attenuates the Response to Anti-VEGF Treatment
Recent clinical trials of VEGF inhibitors have shown promise in the treatment of recurrent glioblastomas (GBM). However, the survival benefit is usually short-lived as tumors escape anti-VEGF therapies. Here we tested the hypothesis that Platelet Derived Growth Factor-C (PDGF-C), an isoform of the PDGF family, affects GBM progression independent of VEGF pathway and hinders anti-VEGF therapy.We first showed that PDGF-C is present in human GBMs. Then, we overexpressed or downregulated PDGF-C in a human GBM cell line, U87MG, and grew them in cranial windows in nude mice to assess vessel structure and function using intravital microscopy. PDGF-C overexpressing tumors had smaller vessel diameters and lower vascular permeability compared to the parental or siRNA-transfected tumors. Furthermore, vessels in PDGF-C overexpressing tumors had more extensive coverage with NG2 positive perivascular cells and a thicker collagen IV basement membrane than the controls. Treatment with DC101, an anti-VEGFR-2 antibody, induced decreases in vessel density in the parental tumors, but had no effect on the PDGF-C overexpressing tumors.These results suggest that PDGF-C plays an important role in glioma vessel maturation and stabilization, and that it can attenuate the response to anti-VEGF therapy, potentially contributing to escape from vascular normalization
Making the invisible visible: a systematic review of sexual minority women’s health in Southern Africa
Background: Over the past two decades research on sexual and gender minority (lesbian, gay, bisexual and transgender; LGBT) health has highlighted substantial health disparities based on sexual orientation and gender identity in many parts of the world. We systematically reviewed the literature on sexual minority women’s (SMW) health in Southern Africa, with the objective of identifying existing evidence and pointing out knowledge gaps around the health of this vulnerable group in this region. Methods: A systematic review of publications in English, French, Portuguese or German, indexed in PubMed or MEDLINE between the years 2000 and 2015, following PRISMA guidelines. Additional studies were identified by searching bibliographies of identified studies. Search terms included (Lesbian OR bisexual OR “women who have sex with women”), (HIV OR depression OR “substance use” OR “substance abuse” OR “mental health” OR suicide OR anxiety OR cancer), and geographical specification. All empirical studies that used quantitative or qualitative methods, which contributed to evidence for SMW’s health in one, a few or all of the countries, were included. Theoretical and review articles were excluded. Data were extracted independently by 2 researchers using predefined data fields, which included a risk of bias/quality assessment. Results: Of 315 hits, 9 articles were selected for review and a further 6 were identified through bibliography searches. Most studies were conducted with small sample sizes in South Africa and focused on sexual health. SMW included in the studies were racially and socio-economically heterogeneous. Studies focused predominately on young populations, and highlighted substance use and violence as key health issues for SMW in Southern Africa. Conclusions: Although there are large gaps in the literature, the review highlighted substantial sexual-orientationrelated health disparities among women in Southern Africa. The findings have important implications for public health policy and research, highlighting the lack of population-level evidence on the one hand, and the impact of criminalizing laws around homosexuality on the other hand
The Gene Ontology resource: enriching a GOld mine
The Gene Ontology Consortium (GOC) provides the most comprehensive resource currently available for computable knowledge regarding the functions of genes and gene products. Here, we report the advances of the consortium over the past two years. The new GO-CAM annotation framework was notably improved, and we formalized the model with a computational schema to check and validate the rapidly increasing repository of 2838 GO-CAMs. In addition, we describe the impacts of several collaborations to refine GO and report a 10% increase in the number of GO annotations, a 25% increase in annotated gene products, and over 9,400 new scientific articles annotated. As the project matures, we continue our efforts to review older annotations in light of newer findings, and, to maintain consistency with other ontologies. As a result, 20 000 annotations derived from experimental data were reviewed, corresponding to 2.5% of experimental GO annotations. The website (http://geneontology.org) was redesigned for quick access to documentation, downloads and tools. To maintain an accurate resource and support traceability and reproducibility, we have made available a historical archive covering the past 15 years of GO data with a consistent format and file structure for both the ontology and annotations

Art-based reflections from 12 years of adolescent health and development-related research in South Africa
This paper presents empirical and methodological findings from an art-based, participatory process with a group (n = 16) of adolescent and young advisors in the Western Cape Province of South Africa. In a weekend workshop, participants reflected on their participation in 12 years of health and development-related research through theatre, song, visual methodologies and semi-structured interviews. Empirical findings suggest that participants interpreted the group research encounter as a site of empowerment, social support and as a socio-political endeavour. Through song, theatre and a mural illustration, they demonstrated that they value ‘unity’ in research, with the aim of ameliorating the conditions of adolescents and young people in other parts of South Africa and the continent. Methodological findings document how participants deployed art-based approaches from South Africa’s powerful history of activism, including the struggle against apartheid, the fight for anti-retroviral therapy and more recent social movements towards decolonization
