Clustering affordable care act qualified health plans to understand how and where insurance facilitates or impedes access to HIV prevention.

Background: With access to and uptake of pre-exposure prophylaxis (PrEP), the United States can prevent new HIV infections. To end the HIV epidemic, health insurance plans must facilitate access to comprehensive preventive care benefits. Since plan benefit designs vary considerably by plan, it is difficult to systematically determine plans that facilitate and restrict preventive services for PrEP.

Alcohol and cannabis co-use: Probing subjective response in eliciting cross-substance craving.

The co-use of alcohol and cannabis is rising in prevalence, yet the mechanisms driving individuals to co-use are not well understood. Subjective response to alcohol or cannabis may predict the desire to use either substance. However, which specific facets of subjective response predict cross-substance craving remains unclear.

An improved high-resolution method for quantitative separation of empty and filled AAV8 capsids by strong anion exchange HPLC.

Cell and gene therapy (CGT) is a field of therapeutic medicine that aims to treat, prevent, and cure diseases using engineered cells (stem cells, immune cells, and differentiated adult or fetal cells), vectors [Adeno Associated Virus (AAV), Adeno Virus (AV), Herpes Simplex Virus (HSV), Baculo Virus (BV), Lenti Virus (LV), Retro Virus (RV), etc.], and other carriers [non-viral vectors, virus-like particles (VLP), Lipid Nano-Particles (LNP), etc.].

The Dual Task Ball Balancing Test and Its Association With Cognitive Function: Algorithm Development and Validation.

Background: Dual task paradigms are thought to offer a quantitative means to assess cognitive reserve and the brain's capacity to allocate resources in the face of competing cognitive demands. The most common dual task paradigms examine the interplay between gait or balance control and cognitive function. However, gait and balance tasks can be physically challenging for older adults and may pose a risk of falls.

Examining the moderating role of cannabis use on the relationship between alcohol consumption and inflammation in individuals with alcohol use disorder.

Inflammation appears to be a critical mechanism in the development of alcohol use disorder (AUD) and a consequence of chronic alcohol use. The potential anti-inflammatory properties of cannabis may modulate the proinflammatory effects of alcohol. This study sought to extend previous work investigating the relationship between alcohol consumption, cannabis use and circulating interleukin (IL)-6 levels in a sample with AUD.

Spatial Accessibility and Uptake of Pediatric COVID-19 Vaccinations by Social Vulnerability.

Background And Objectives: Geographic accessibility predicts pediatric preventive care utilization, including vaccine uptake. However, spatial inequities in the pediatric coronavirus disease 2019 (COVID-19) vaccination rollout remain underexplored. We assessed the spatial accessibility of vaccination sites and analyzed predictors of vaccine uptake.

Endpoints for Pharmacotherapy Trials for Alcohol Use Disorder.

Alcohol use disorder (AUD) is a debilitating disorder, yet currently approved pharmacotherapies to treat AUD are under-utilized. The three medications approved by the US Food and Drug Administration (FDA) for the indication of AUD are disulfiram, acamprosate, and naltrexone. The current landscape of pharmacotherapies for AUD suggests opportunities for improvement.

Lacticaseibacillus rhamnosus CRL 2244 secreted metabolites display killing and antibiotic synergistic activity against multi-drug resistant pathogens.

A growing increase in the number of serious infections caused by multidrug resistant bacteria (MDR) is challenging our society. Despite efforts to discover novel therapeutic options, few antibiotics targeting MDR have been approved by the Food and Drug Administration (FDA). Lactic acid bacteria have emerged as a promising therapeutic alternative due to their demonstrated ability to combat MDR pathogens in vitro.

Evaluating Chromosome Instability and Genotoxicity Through Single Cell Quantitative Imaging Microscopy.

Across eukaryotes, genome stability is essential for normal cell function, physiology, and species survival. Aberrant expression of key genes or exposure to genotoxic agents can have detrimental effects on genome stability and contribute to the development of various diseases, including cancer. Chromosome instability (CIN), or ongoing changes in chromosome complements, is a frequent form of genome instability observed in cancer and is a driver of genetic and cell-to-cell heterogeneity that can be rapidly detected and quantitatively assessed using surrogate markers of CIN.

Reconstructing parent genomes using siblings and other relatives.

Reconstructing the DNA of ancestors from their descendants has the potential to empower phenotypic analyses (including association and genetic nurture studies), improve pedigree reconstruction, and shed light on the ancestral population and phenotypes of ancestors. We developed HAPI-RECAP, a method that reconstructs the DNA of parents from full siblings and their relatives. This tool leverages HAPI2's output, a new phasing approach that applies to siblings (and optionally one or both parents) and reliably infers parent haplotypes but does not link the ungenotyped parents' DNA across chromosomes or between segments flanking ambiguities.

Spatial and Temporal Resolution of Cyanobacterial Bloom Chemistry Reveals an Open-Ocean as a Talented Producer of Specialized Metabolites.

While the ecological role that sp. play in nitrogen fixation has been widely studied, little information is available on potential specialized metabolites that are associated with blooms and standing stock colonies. While a collection of biological material from a bloom event from North Padre Island, Texas, in 2014 indicated that this species was a prolific producer of chlorinated specialized metabolites, additional spatial and temporal resolution was needed.

Return to work and activity after rib-fixation for acute chest trauma: first application of a validated patient-reported outcomes assessment tool.

Objectives: Rib fractures present a heavy pain and functional burden in trauma. Our primary aim was to determine return to work in patients with acute rib fractures requiring surgical stabilization of rib fractures. Our secondary outcomes were pain and quality of life.

Managing Modern Antiretroviral Therapy in the Intensive Care Unit: Overcoming Challenges for Critically Ill People With Human Immunodeficiency Virus.

People with human immunodeficiency virus (HIV) have a 50% excess risk for intensive care unit (ICU) admission, often for non-HIV-related conditions. Despite this, clear guidance for managing antiretroviral therapy (ART) in this setting is lacking. Selecting appropriate ART in the ICU is complex due to drug interactions, absorption issues, and dosing adjustments.

National Hospitalization Rates and In-Hospital Mortality Rates of HIV-Related Opportunistic Infections in the United States, 2011-2018.

Background: Human immunodeficiency virus (HIV)-related opportunistic infections (OIs) cause substantial morbidity and mortality among people with HIV (PWH). US hospitalization and in-hospital mortality rates associated with OIs have not been published using data from the past decade.

Methods: We analyzed the National Inpatient Sample for the years 2011 through 2018.

PROTACs: Current and Future Potential as a Precision Medicine Strategy to Combat Cancer.

Proteolysis targeting chimeras (PROTAC) are an emerging precision medicine strategy, which targets key proteins for proteolytic degradation to ultimately induce cancer cell killing. These hetero-bifunctional molecules hijack the ubiquitin proteasome system to selectively add polyubiquitin chains onto a specific protein target to induce proteolytic degradation. Importantly, PROTACs have the capacity to target virtually any intracellular and transmembrane protein for degradation, including oncoproteins previously considered undruggable, which strategically positions PROTACs at the crossroads of multiple cancer research areas.

Introduction: There is an urgent need for scalable strategies for treating overweight and obesity in clinical settings. PROPS 2.0 (Partnerships for Reducing Overweight and Obesity with Patient-Centered Strategies 2.

The role of sex in daily levels of high-risk alcohol and cannabis co-use.

Background: Co-use of alcohol and cannabis is highly prevalent and may be associated with negative outcomes. The intersection between alcohol and cannabis use remains poorly understood. The present study assessed this intersection and the moderating effects of sex on the daily levels of high-risk alcohol and cannabis co-use.

Geographic Variation in Qualified Health Plan Coverage and Prior Authorization Requirements for HIV Preexposure Prophylaxis.

Importance: HIV preexposure prophylaxis (PrEP) is a key component of the Ending the HIV Epidemic (EHE) Initiative to curb new HIV diagnoses. In October 2019, emtricitabine/tenofovir alafenamide was added as an approved formulation for PrEP in addition to emtricitabine/tenofovir disoproxil fumarate; despite availability of another formulation with a similar prevention indication, variations in coverage may limit access.

Objective: To assess qualified health plan (QHP) coverage, prior authorization (PA) requirements, and specialty tiering for emtricitabine/tenofovir disoproxil fumarate and emtricitabine/tenofovir alafenamide following emtricitabine/tenofovir alafenamide approval as a PrEP treatment.

Sexual Exposures Associated With Mpox Infection: California, November 2022 to June 2023.

Background: Exposures associated with mpox infection remain imperfectly understood.

Methods: We conducted a case-control study enrolling participants who received molecular tests for mpox/orthopoxvirus in California from November 2022 through June 2023. We collected data on behaviors during a 21-day risk period before symptom onset or testing among mpox case patients and test-negative controls.

Survey of NF1 inactivation by surrogate immunohistochemistry in ovarian carcinomas.

Objective: Inhibition of the MAPK pathway by MEK inhibitors (MEKi) is currently a therapeutic standard in several cancer types, including ovarian low-grade serous carcinoma (LGSC). A common MAPK pathway alteration in tubo-ovarian high-grade serous carcinoma (HGSC) is the genomic inactivation of neurofibromin 1 (NF1). The primary objectives of our study were to survey the prevalence of NF1 inactivation in the principal ovarian carcinoma histotype as well as to evaluate its associations with clinico-pathological parameters and key biomarkers including BRCA1/2 status in HGSC.
