The Tulumbe! Partnership: a case study in developing a community-led research agenda to address HIV among African immigrants in the United States.

Grassroots, community organizations are trusted resources within communities, which puts them in an ideal position to effectively engage individuals impacted by health inequities in defining meaningful research priorities. A community-centered approach to HIV research is critical for African immigrants living in the United States, who experience stigma and other socio-structural barriers to HIV prevention, care, and research engagement. Supporting community organizations with financial resources and capacity building activities to lead the development of research agendas ensures better alignment with community interests and fosters sustainability.

Astrocytes initiate autophagic flux and maintain cell viability after internalizing non-active native extracellular α-synuclein.

Astrocytes are tasked with regulating the synaptic environment. Early stages of various neurodegenerative diseases are characterized by synapse loss, and astrocytic atrophy and dysfunction has been proposed as a possible cause. α-Synuclein (αS) is a highly expressed neuronal protein located in the synapse that can be released in the extracellular space.

IRF2 loss is associated with reduced MHC I pathway transcripts in subsets of most human cancers and causes resistance to checkpoint immunotherapy in human and mouse melanomas.

Background: In order for cancers to progress, they must evade elimination by CD8 T cells or other immune mechanisms. CD8 T cells recognize and kill tumor cells that display immunogenic tumor peptides bound to MHC I molecules. One of the ways that cancers can escape such killing is by reducing expression of MHC I molecules, and loss of MHC I is frequently observed in tumors.

Managing the unmanageable: evidence-driven approaches to real-world patient prototypes of TP53-mutant myelodysplastic neoplasms and acute myeloid leukemia.

Patients with TP53 aberrations comprise the highest risk subset of all myeloid malignancies. The managerial conundrum of TP53-mutant myelodysplastic neoplasms (MDS) and acute myeloid leukemia (AML) stems from refractoriness to or relapse after conventional chemotherapy, as well as the limited translational success of investigational therapies targeting TP53-mutant cells. Thus far, no targeted therapies have been commercially approved for this mutational subset.

Acute and Critical Care Nurses' Roles in Mass Shootings: An Integrative Review.

Background: From 2018 to 2022, mass shooting incidents in the United States increased by 67.7%. Health care-associated shootings also increased.

Proposed Nutrition Competencies for Medical Students and Physician Trainees: A Consensus Statement.

Importance: In 2022, the US House of Representatives passed a bipartisan resolution (House of Representatives Resolution 1118 at the 117th Congress [2021-2022]) calling for meaningful nutrition education for medical trainees. This was prompted by increasing health care spending attributed to the growing prevalence of nutrition-related diseases and the substantial federal funding via Medicare that supports graduate medical education. In March 2023, medical education professional organizations agreed to identify nutrition competencies for medical education.

Family Management of Hypertension in Brazil: A Cross-Sectional Study.

In Brazil, research indicates that primary family members are the main source of support for individuals with chronic conditions such as hypertension (HTN). The burden of caregiving not only hinders effective HTN management but can also cause stress and anxiety, potentially leading to HTN in caregivers. Despite this, few studies have explored the impact of caregiving on these family members.

Stopping use of E-cigarettes and smoking combustible cigarettes: findings from a large longitudinal digital smoking cessation intervention study in the United States.

Objective: Digital interventions have been widely implemented to promote tobacco cessation. However, implementations of these interventions have not yet considered how participants' e-cigarette use may influence their quitting outcomes. We explored the association of e-cigarette use and quitting smoking within the context of a study testing a digital tobacco cessation intervention among individuals in the United States who were 18 years and older, smoked combustible cigarettes, and enrolled in the intervention between August 2017 and March 2019.

FcRn-enhancing mutations lead to increased and prolonged levels of the HIV CCR5-blocking monoclonal antibody leronlimab in the fetuses and newborns of pregnant rhesus macaques.

Prenatal administration of monoclonal antibodies (mAbs) is a strategy that could be exploited to prevent viral infections during pregnancy and early life. To reach protective levels in fetuses, mAbs must be transported across the placenta, a selective barrier that actively and specifically promotes the transfer of antibodies (Abs) into the fetus through the neonatal Fc receptor (FcRn). Because FcRn also regulates Ab half-life, Fc mutations like the M428L/N434S, commonly known as LS mutations, and others have been developed to enhance binding affinity to FcRn and improve drug pharmacokinetics.

The effect of embryo migration after embryo transfer with fresh oocyte donation cycles on pregnancy outcomes.

Embryo migration is defined as the movement of embryos to implant at the exact site in the endometrial cavity during assisted reproductive technology (ART). We aimed to evaluate the impact of embryo migration on clinical pregnancy (CPR) and live birth rates (LBR) in fresh oocyte donation (OD) cycles. A total of 611 fresh OD cycles was recruited in this prospective cohort study.

Prosthetic conduits have worse outcomes compared with great saphenous vein conduits in femoropopliteal and infrapopliteal bypass in patients with chronic limb-threatening ischemia.

Objective: Single segment great saphenous vein (SSGSV) traditionally has been considered the gold standard conduit for infrainguinal bypass. There are data supporting similar outcomes with prosthetic femoral-popliteal bypass. Moreover, some investigators have advocated for prosthetic conduit for femoral tibial bypass when GSV is inadequate or unavailable.

A Novel Mouse Home Cage Lickometer System Reveals Sex- and Housing-Based Influences on Alcohol Drinking.

Alcohol use disorder (AUD) is a significant global health issue. Despite historically higher rates among men, AUD prevalence and negative alcohol-related outcomes in women are rising. Loneliness in humans has been associated with increased alcohol use, and traditional rodent drinking models involve single housing, presenting challenges for studying social enrichment.

The rising cost of liver transplantation in the United States.

Liver transplantation (LT) is the only curative treatment for end-stage liver disease and significantly improves patient outcomes. However, LT is resource-intensive and costly, with expenditures rising dramatically in recent years. Factors contributing to this increase in cost include expanded transplant criteria, utilization of marginal organs, and broader organ distribution, resulting in significant logistical expenses.
