ABSTRACT

Underrepresentation of Black individuals in genetic research is a longstanding issue. There are well-documented strategies to improve the enrollment of Black participants; however, few studies explore these strategies-as well as the barriers and facilitators for participation-by sampling Black people who have previously participated in genetic research. This study explores the decision-making process of Black adults who have participated in genetic research to identify best practices in the recruitment of Black subjects in genetic research. We conducted 18 semi-structured interviews with Black adults with prior research participation in genetic studies housed at an urban academic medical center in the United States of America (USA). An online survey was conducted with the participants to gather demographic data and information on prior research participation. Trust in research was ascertained with the Corbie-Smith Distrust in Clinical Research Index. Two participants scored high levels of distrust using the validated index. Using thematic content analysis, 4 themes emerged from the interviews: (1) Participants are active players in health system, (2) information is power, and transparency is key, (3) therapeutic alliances and study characteristics facilitate participation, and (4) race pervades the research process. The decision to participate in genetic research for the participants in our study was prompted by participants' internal motivations and facilitated by trust in their doctor, trust in the institution, and ease of participation. Most participants viewed their enrollment in genetic research in the context of their own racial identity and the history of medical racism in the USA.

ABSTRACT

PURPOSE: Existing frameworks to address instances of microaggressions and discrimination in the clinical environment have largely been developed for faculty and resident physicians, creating a lack of resources for medical students. METHODS: We implemented a workshop to prepare pre-clinical medical/dental students to recognize and respond to microaggressions. Participants in three cohorts from 2018 to 2020 completed pre- and post-workshop surveys assessing the prevalence of exposure to clinical microaggressions and the workshop's effect on mitigating commonly perceived barriers to addressing microaggressions. RESULTS: Of 461 first-year medical and dental students who participated, 321 (69.6%) provided survey responses. Over 80% of students reported experiencing microaggressions, with women and URM students over-represented. After the workshop, participants reported significant reductions in barriers to addressing microaggressions and discrimination, including recognizing incidents, uncertainty of what to say or do, lack of allies, lack of familiarity with institutional policies, and uncertainty of clinical relevance. The workshop was similarly effective in-person and virtual formats. CONCLUSIONS: Most medical/dental student respondents reported experiencing microaggressions in the clinical setting, particularly female and URM students. Our workshop mitigated most perceived challenges to responding to microaggressions. Future interventions across institutions should continue to equip students with the tools they need to address and respond to microaggressions.

ABSTRACT

Apolipoprotein E4 (ApoE4) is the most important and prevalent risk factor for late-onset Alzheimer's disease (AD). The isoelectric point of ApoE4 matches the pH of the early endosome (EE), causing its delayed dissociation from ApoE receptors and hence impaired endolysosomal trafficking, disruption of synaptic homeostasis, and reduced amyloid clearance. We have shown that enhancing endosomal acidification by inhibiting the EE-specific sodium-hydrogen exchanger 6 (NHE6) restores vesicular trafficking and normalizes synaptic homeostasis. Remarkably and unexpectedly, loss of NHE6 (encoded by the gene Slc9a6) in mice effectively suppressed amyloid deposition even in the absence of ApoE4, suggesting that accelerated acidification of EEs caused by the absence of NHE6 occludes the effect of ApoE on amyloid plaque formation. NHE6 suppression or inhibition may thus be a universal, ApoE-independent approach to prevent amyloid buildup in the brain. These findings suggest a novel therapeutic approach for the prevention of AD by which partial NHE6 inhibition reverses the ApoE4-induced endolysosomal trafficking defect and reduces plaque load.

ABSTRACT

BACKGROUND: The Covid-19 pandemic is straining healthcare systems in the US and globally, which has wide-reaching implications for health. Women experience unique health risks and outcomes influenced by their gender, and this narrative review aims to outline how these differences are exacerbated in the Covid-19 pandemic. OBSERVATIONS: It has been well described that men suffer from greater morbidity and mortality once infected with SARS-CoV-2. This review analyzed the health, economic, and social systems that result in gender-based differences in the areas healthcare workforce, reproductive health, drug development, gender-based violence, and mental health during the Covid-19 pandemic. The increased risk of certain negative health outcomes and reduced healthcare access experienced by many women are typically exacerbated during pandemics. We assess data from previous disease outbreaks coupled with literature from the Covid-19 pandemic to examine the impact of gender on women's SARS-CoV-2 exposure and disease risks and overall health status during the Covid-19 pandemic. CONCLUSIONS: Gender differences in health risks and implications are likely to be expanded during the Covid-19 pandemic. Efforts to foster equity in health, social, and economic systems during and in the aftermath of Covid-19 may mitigate the inequitable risks posed by pandemics and other times of healthcare stress.

ABSTRACT

OBJECTIVES: A variety of health services delivered via the Internet, or "eHealth interventions," to support caregivers of people with dementia have shown evidence of effectiveness, but only a small number are put into practice. This study aimed to investigate whether, how and why their implementation took place. METHODS: This qualitative study followed up on the 12 publications included in Boots et al.'s (2014) widely cited systematic review on eHealth interventions for informal caregivers of people with dementia, in order to explore further implementation into practice. Publicly available online information, implementation readiness (ImpRess checklist scores), and survey responses were assessed. FINDINGS: Two interventions were freely available online, two were available in a trial context, and one was exclusively available to clinical staff previously involved in the research project. The remaining seven were unavailable. All scores on the ImpRess checklist were at 50% or lower of the total, indicating that the interventions were not ready to implement at the time of the Boots et al. (2014) review, though some interventions were scored as more implementation-ready in subsequent follow-up publications. Responses to the survey were received from six out of twelve authors. Key learnings from the survey included the importance of the involvement of stakeholders at all stages of the process, as well as the flexible adaptation and commercialization of the intervention. CONCLUSIONS: In general, low levels of implementation readiness were reported and often the information necessary to assess implementation readiness was unavailable. The only two freely available interventions had long-term funding from aging foundations. Authors pointed to the involvement of financial gatekeepers in the development process and the creation of a business model early on as important facilitators to implementation. Future research should focus on the factors enabling sustainable implementation.

ABSTRACT

The vast bacteriophage population harbors an immense reservoir of genetic information. Almost 2000 phage genomes have been sequenced from phages infecting hosts in the phylum Actinobacteria, and analysis of these genomes reveals substantial diversity, pervasive mosaicism, and novel mechanisms for phage replication and lysogeny. Here, we describe the isolation and genomic characterization of 46 phages from environmental samples at various geographic locations in the U.S. infecting a single Arthrobacter sp. strain. These phages include representatives of all three virion morphologies, and Jasmine is the first sequenced podovirus of an actinobacterial host. The phages also span considerable sequence diversity, and can be grouped into 10 clusters according to their nucleotide diversity, and two singletons each with no close relatives. However, the clusters/singletons appear to be genomically well separated from each other, and relatively few genes are shared between clusters. Genome size varies from among the smallest of siphoviral phages (15,319 bp) to over 70 kbp, and G+C contents range from 45-68%, compared to 63.4% for the host genome. Although temperate phages are common among other actinobacterial hosts, these Arthrobacter phages are primarily lytic, and only the singleton Galaxy is likely temperate.
