Psychological Challenges of Adults With Severe Mental Illness During the COVID-19 Pandemic.

The COVID-19 pandemic was an unprecedented global health crisis. Vulnerable populations with preexisting mental illness have been disproportionately burdened and may experience adverse mental health outcomes related to the COVID-19 pandemic. Our objective was to evaluate the association between COVID-19 diagnosis, known exposure to COVID-19, sheltering in place, symptom severity, psychological distress, and depression severity among adults with severe mental illness (SMI).

DNA methylation modulates nucleosome retention in sperm and H3K4 methylation deposition in early mouse embryos.

In the germ line and during early embryogenesis, DNA methylation (DNAme) undergoes global erasure and re-establishment to support germ cell and embryonic development. While DNAme acquisition during male germ cell development is essential for setting genomic DNA methylation imprints, other intergenerational roles for paternal DNAme in defining embryonic chromatin are unknown. Through conditional gene deletion of the de novo DNA methyltransferases Dnmt3a and/or Dnmt3b, we observe that DNMT3A primarily safeguards against DNA hypomethylation in undifferentiated spermatogonia, while DNMT3B catalyzes de novo DNAme during spermatogonial differentiation.

Demographic and Clinical Characteristics Predicting Missed Clinic Visits among Patients Living with HIV on Antiretroviral Treatment in Kinshasa and Haut-Katanga Provinces of the Democratic Republic of Congo.

Background: Patients living with HIV (PLHIV) often face challenges that contribute to missed clinical care which can impact their health outcomes.

Methods: This retrospective quantitative study comprised 5338 adults living with HIV who received antiretroviral treatment (ART) for 12 months, from July 2018 to June 2019 in Kinshasa and Haut-Katanga provinces of the Democratic Republic of Congo. Descriptive statistics were computed to show the level of missed appointments for ART.

A systematic review of rural community-based mental health interventions in the United States.

Background: Mental health impacts a person's quality of life and ability to engage in healthy behaviors. Rural communities in the United States have limited access to mental and behavioral health treatment.

Aim: To conduct a systematic review to identify existing rural community-based mental health interventions and identify commonalities and differences by extracting study attributes and intervention components.

Courtesy Stigma and HIV Professionals: A Brief Review of Implications for Psychosocial and Professional Well-Being.

The impact of HIV-related stigma on social workers, clinicians, counselors, and advocates working in organizations serving people living with HIV (PLWH), is rarely considered. Professionals experience "courtesy stigma" when working with or on behalf of PLWH, regardless of their personal HIV status. PubMed, Medline, and PsycInfo databases, along with a review of relevant reference lists and referrals, identified 13 studies addressing this phenomenon.

The More Things Change, the More They Stay the Same: HIV/AIDS Myths and Misinformation in the Rural United States.

Approaches to HIV/AIDS prevention and treatment have made significant advances since the beginning of the epidemic. However, HIV myths and misinformation continue to persist, stymieing efforts to end the epidemic in the United States, particularly in rural areas. The present study's purpose was to identify prevalent myths and misinformation about HIV/AIDS in the rural United States.

Cohesin and CTCF control the dynamics of chromosome folding.

In mammals, interactions between sequences within topologically associating domains enable control of gene expression across large genomic distances. Yet it is unknown how frequently such contacts occur, how long they last and how they depend on the dynamics of chromosome folding and loop extrusion activity of cohesin. By imaging chromosomal locations at high spatial and temporal resolution in living cells, we show that interactions within topologically associating domains are transient and occur frequently during the course of a cell cycle.

HIV viral load suppression before and after COVID-19 in Kinshasa and Haut Katanga, Democratic Republic of the Congo.

Background: The coronavirus disease 2019 (COVID-19) pandemic resulted in unique programmatic opportunities to test hypotheses related to the initiation of antiretroviral treatment (ART) and viral load (VL) suppression during a global health crisis, which would not otherwise have been possible.

Objectives: To generate practice-relevant evidence on the impact of initiating ART pre-COVID-19 versus during the COVID-19 pandemic on HIV VL.

Method: Logistic regression was performed on data covering 6596 persons with HIV whose VL data were available, out of 36 585 persons who were initiated on ART between 01 April 2019 and 30 March 2021.

Using a Measurement Model to Reconceptualize the Church Experiences of Black Men who have Sex with Men.

Religious spaces have proven to be effective sites of health intervention among Black Americans. Less is known about how religious environments impact the health of subgroups of Black Americans, specifically Black men who have sex with men (MSM). Using data from the Promoting Our Worth, Equality, and Resilience study, we explored the factor structure of a 10-item religious environment scale among Black MSM (N = 2,482).

Nonlinear control of transcription through enhancer-promoter interactions.

Chromosome structure in mammals is thought to regulate transcription by modulating three-dimensional interactions between enhancers and promoters, notably through CTCF-mediated loops and topologically associating domains (TADs). However, how chromosome interactions are actually translated into transcriptional outputs remains unclear. Here, to address this question, we use an assay to position an enhancer at large numbers of densely spaced chromosomal locations relative to a fixed promoter, and measure promoter output and interactions within a genomic region with minimal regulatory and structural complexity.

Structural Inequities, HIV Community-Based Organizations, and the End of the HIV Epidemic.

Community-based organizations (CBOs) are integral to achieving the goal of Ending the HIV epidemic (EHE). Their familiarity with and proximity to communities position them to effectively implement strategies necessary to address determinants of health through their formal and informal medical and social services. However, structural inequities have contributed to the demise of many organizations that were instrumental in early responses to the HIV epidemic.

Psychometric Testing of the Daily Spiritual Experiences Scale (DSES) Among Black Gay, Bisexual, and Other Sexual Minority Men (SMM) and Black Transwomen in the Deep South: The MARI Study.

Spirituality is a well-established protective psychosocial determinant of health. The current study examined the psychometric properties of the Daily Spiritual Experiences Scale (DSES) among Black gay, bisexual and other sexual minority men (SMM) and Black transwomen (TW) in the Deep South. Data were collected via self-interview technology and analyzed using factor analyses and correlation coefficients.

Spirituality, self-compassion, and anxiety among sexual minority men: a longitudinal mediation analysis.

Background And Objective: Research related to anxiety among sexual minority men (SMM) typically focuses on risk factors. It has seldom examined factors that may be associated with lower levels of anxiety. This gap in the literature represents an opportunity to explore positive psychological factors that may be related to lower levels of anxiety among this group.

Mechanical oscillations orchestrate axial patterning through Wnt activation in .

Mechanical input shapes cell fate decisions during development and regeneration in many systems, yet the mechanisms of this cross-talk are often unclear. In regenerating tissue spheroids, periodic osmotically driven inflation and deflation cycles generate mechanical stimuli in the form of tissue stretching. Here, we demonstrate that tissue stretching during inflation is important for the appearance of the head organizer—a group of cells that secrete the Wnt3 ligand.

Examining social activity, need to belong, and depression among college students.

Objective: Prior research suggests that social connectedness is associated with lower levels of depression among college students. The aim of this exploratory study was to determine if an association existed between social activity, need to belong, and depression. Variations in study measures by race, gender, and student status were also explored.

The BTB-domain transcription factor ZBTB2 recruits chromatin remodelers and a histone chaperone during the exit from pluripotency.

Transcription factors (TFs) harboring broad-complex, tramtrack, and bric-a-brac (BTB) domains play important roles in development and disease. These BTB domains are thought to recruit transcriptional modulators to target DNA regions. However, a systematic molecular understanding of the mechanism of action of this TF family is lacking.

BANP opens chromatin and activates CpG-island-regulated genes.

The majority of gene transcripts generated by RNA polymerase II in mammalian genomes initiate at CpG island (CGI) promoters, yet our understanding of their regulation remains limited. This is in part due to the incomplete information that we have on transcription factors, their DNA-binding motifs and which genomic binding sites are functional in any given cell type. In addition, there are orphan motifs without known binders, such as the CGCG element, which is associated with highly expressed genes across human tissues and enriched near the transcription start site of a subset of CGI promoters.

Cooperation between HDAC3 and DAX1 mediates lineage restriction of embryonic stem cells.

Mouse embryonic stem cells (mESCs) are biased toward producing embryonic rather than extraembryonic endoderm fates. Here, we identify the mechanism of this barrier and report that the histone deacetylase Hdac3 and the transcriptional corepressor Dax1 cooperatively limit the lineage repertoire of mESCs by silencing an enhancer of the extraembryonic endoderm-specifying transcription factor Gata6. This restriction is opposed by the pluripotency transcription factors Nr5a2 and Esrrb, which promote cell type conversion.

Generating Intervention Concepts for Reducing Adolescent Relationship Abuse Inequities Among Sexual and Gender Minority Youth: Protocol for a Web-Based, Longitudinal, Human-Centered Design Study.

Background: Sexual and gender minority youth (SGMY; eg, lesbian, gay, bisexual, and transgender youth) are at greater risk than their cisgender heterosexual peers for adolescent relationship abuse (ARA; physical, sexual, or psychological abuse in a romantic relationship). However, there is a dearth of efficacious interventions for reducing ARA among SGMY. To address this intervention gap, we designed a novel web-based methodology leveraging the field of human-centered design to generate multiple ARA intervention concepts with SGMY.

Multi-omics profiling of mouse gastrulation at single-cell resolution.

Formation of the three primary germ layers during gastrulation is an essential step in the establishment of the vertebrate body plan and is associated with major transcriptional changes. Global epigenetic reprogramming accompanies these changes, but the role of the epigenome in regulating early cell-fate choice remains unresolved, and the coordination between different molecular layers is unclear. Here we describe a single-cell multi-omics map of chromatin accessibility, DNA methylation and RNA expression during the onset of gastrulation in mouse embryos.

Issue of Compliance with Use of Personal Protective Equipment among Wastewater Workers across the Southeast Region of the United States.

Wastewater workers are exposed to different occupational hazards such as chemicals, gases, viruses, and bacteria. Personal protective equipment (PPE) is a significant factor that can reduce or decrease the probability of an accident from hazardous exposures to chemicals and microbial contaminants. The purpose of this study was to examine wastewater worker's beliefs and practices on wearing PPE through the integration of the Health Belief Model (HBM), identify the impact that management has on wastewater workers wearing PPE, and determine the predictors of PPE compliance among workers in the wastewater industry.

The oral nitrate-reducing capacity correlates with peak power output and peak oxygen uptake in healthy humans.

Interest in inorganic nitrate and nitrite has grown substantially over the past decade as research has revealed the role of these anions in enhancing nitric oxide (NO) availability through an oral pathway. Nitrite synthesis in the mouth seems to be an important mechanism to feed the circulatory system with this anion. This is interesting since greater plasma nitrite concentration has been associated with better fitness levels in humans, but this question has not been investigated in relation to salivary nitrite concentration.
