RESUMO

Sexual minority women (SMW) experience higher levels of depression compared to heterosexual women, and bisexual women show higher levels than lesbian women. Sexual orientation concealment is a risk factor for depressive symptoms among SMW. Hope is protective against depressive symptoms in diverse samples, but limited research in this area has centered on SMW. This study examined the role of hope and its components, agency and pathways, as moderators of the relation between sexual orientation concealment and depressive symptoms, and whether the moderating effects were conditional on sexual orientation. An international sample of 218 lesbian women aged 18 to 69 (M = 32.93 years, SD = 12.75) and 230 bisexual women aged 18 to 67 (M = 27.83 years, SD = 7.52) completed an online survey. Hope, agency, and pathways did not moderate the relation between sexual orientation concealment and depressive symptoms. The significant negative relations between hope and depressive symptoms, and between agency and depressive symptoms, were moderated by sexual orientation: the relations were stronger among lesbian women than bisexual women. Results suggest that increasing levels of hope and agency through clinical intervention may reduce depressive symptoms for both groups of women, with more pronounced effects among lesbian women.

RESUMO

Depression is a prevalent mental health issue for sexual minority men (SMM), with the internalization of sexual identity-based stigma a key risk factor. Self-warmth is a protective factor and self-coldness is a risk factor for depressive symptoms, yet limited research in this area has focused on SMM. In the present study, an international sample of 1,285 gay and 487 bisexual men completed measures of depression, internalized heterosexism, and self-warmth/self-coldness. A multiple linear regression showed that internalized heterosexism explained 0.4% unique variance, self-warmth explained 0.5% unique variance, and self-coldness explained 18.8% unique variance in depressive symptoms. Self-warmth was directly and indirectly related to lower levels of depressive symptoms among SMM. In contrast, self-coldness was directly related to higher levels of depressive symptoms among SMM, and indirectly related to higher levels of depressive symptoms only for gay men. Findings should inform work aiming primarily to reduce self-coldness among SMM, thereby reducing depressive symptoms.

RESUMO

COVID-19 has presented unique and unprecedented struggles for all people, yet they tend to be magnified among marginalized communities. Indeed, in the United States, transgender (trans) people experience oppression in many facets of their lives, which places them at an increased risk for both COVID-19 exposure and complications. This oppression can be broadly categorized into two distinct, yet interrelated categories: health disparities (e.g., decreased immune health) and structural barriers (e.g., employment discrimination, policing). Recent scholarship has examined trans people's risk for COVID-19 exposure and mortality, however few articles examine intersectional identities, and, to our knowledge, none have interrogated oppressive power structures (e.g., the prison industrial complex). We aim to fill these critical gaps and argue that it is imperative for cisgender people to partner with trans communities to dismantle these harmful systems, positively impacting the lives of trans individuals during the pandemic and beyond. We make several key recommendations for researchers, policymakers, healthcare workers, and allies to do so.

RESUMO

Race plays an important role in how people think, develop, and behave. In the current article, we queried more than 26,000 empirical articles published between 1974 and 2018 in top-tier cognitive, developmental, and social psychology journals to document how often psychological research acknowledges this reality and to examine whether people who edit, write, and participate in the research are systematically connected. We note several findings. First, across the past five decades, psychological publications that highlight race have been rare, and although they have increased in developmental and social psychology, they have remained virtually nonexistent in cognitive psychology. Second, most publications have been edited by White editors, under which there have been significantly fewer publications that highlight race. Third, many of the publications that highlight race have been written by White authors who employed significantly fewer participants of color. In many cases, we document variation as a function of area and decade. We argue that systemic inequality exists within psychological research and that systemic changes are needed to ensure that psychological research benefits from diversity in editing, writing, and participation. To this end, and in the spirit of the field's recent emphasis on metascience, we offer recommendations for journals and authors.

RESUMO

Two nanometre gold nanoparticles (AuNPs), bearing sugar moieties and/or thiol-polyethylene glycol-amine (PEG-amine), were synthesised and evaluated for their in vitro toxicity and ability to radiosensitise cells with 220 kV and 6 MV X-rays, using four cell lines representing normal and cancerous skin and breast tissues. Acute 3 h exposure of cells to AuNPs, bearing PEG-amine only or a 50:50 ratio of alpha-galactose derivative and PEG-amine resulted in selective uptake and toxicity towards cancer cells at unprecedentedly low nanomolar concentrations. Chemotoxicity was prevented by co-administration of N-acetyl cysteine antioxidant, or partially prevented by the caspase inhibitor Z-VAD-FMK. In addition to their intrinsic cancer-selective chemotoxicity, these AuNPs acted as radiosensitisers in combination with 220 kV or 6 MV X-rays. The ability of AuNPs bearing simple ligands to act as cancer-selective chemoradiosensitisers at low concentrations is a novel discovery that holds great promise in developing low-cost cancer nanotherapeutics.
