Brief Report: Internalized Poverty-Related Stigma and Interpersonal Violence Among Women Living With HIV in the United States.

Background: Interpersonal violence (IPV) affects half of women living with HIV (WLHIV) in the United States and has important consequences for mental health and HIV outcomes. Although different types of stigmas (eg, HIV- or sexual identity-related) are associated with increased risk of IPV, the relationship between poverty-related stigma and IPV is unclear, even though poverty frequently co-occurs with IPV.

Methods: Data from up to 4 annual visits (2016-2020) were collected from 374 WLHIV enrolled in a substudy of the Women's Interagency HIV Study (now known as Multicenter AIDS Cohort Study/Women's Interagency HIV Study Combined Cohort Study) at 4 sites across the United States.

Effects of the anti-inflammatory pentoxifylline on psychiatric and neuropsychiatric conditions: exploring various off-label utilities with meta-analyses.

Background: Chronic inflammation has been linked to many psychiatric disorders, and therefore, pertinent anti-inflammatory therapies have been empirically evaluated for management. An enduring example of long-term safety, attainability, and versatility has been pentoxifylline (PTX). PTX is a phosphodiesterase inhibitor that modulates inflammatory mediators and affects most blood components and the blood vessels.

Modifiable Risk Factors for Stroke in Syria: A Nationwide Multi-centre Case-Control Study.

Stroke is the second-leading cause of death worldwide, including in Syria, and the third-leading cause of death and disability combined. With approximately 90% of strokes worldwide linked to modifiable risk factors, identifying and quantifying these factors within a specific population is essential for effective prevention. This is the first study to investigate primary risk factors for stroke in Syria.

Pentoxifylline in COVID-19 and considerations for its research in long COVID.

Introduction: Pentoxifylline (PTX) affects most blood components and the blood vessels, potentially modulating various conditions. Due to its impact on markers linked to COVID-19 severity, research has explored PTX for acute COVID-19. Following the widespread administration of COVID-19 vaccinations, there has been a notable and consistently growing increase in research focusing on long COVID.

The Impact of Wildfire Smoke on Asthma Control in California: A Microsimulation Approach.

Wildfire smoke exposure leads to poorer health among those with pre-existing conditions such as asthma. Particulate matter in wildfire smoke can worsen asthma control, cause acute exacerbations, and increase health resource utilization (HRU) and costs. Research to date has been retrospective with few opportunities to project changes in underlying asthma control and HRU given exposure to wildfire smoke.

Bridging Language Barriers in COVID-19 Research: Descriptive Study of AccesoCovid.com's Reach and User Engagement.

Background: The COVID-19 pandemic underscored the challenge of swiftly disseminating research findings to a global audience. Language barriers further exacerbated disparities in access to timely scientific information, particularly for non-English speaking communities. The majority of COVID-19 research was published in English, limiting accessibility for Spanish-speaking populations.

Effect of wildfire on the prevalence of opioid misuse through anxiety among young adults in the United States: a modeling study.

Background: Exposure to climate change events like wildfires can lead to health and mental health problems. While conceptual frameworks have been hypothesized describing the potential relationship between disaster exposure and substance use, the association remains under-researched and unquantified.

Methods: We constructed a quantitative portrayal of one proposed conceptual framework that focuses on the intermediary role of anxiety.

Liver-specific Mettl14 deletion induces nuclear heterotypia and dysregulates RNA export machinery.

Modification of RNA with N-methyladenosine (mA) has gained attention in recent years as a general mechanism of gene regulation. In the liver, mA, along with its associated machinery, has been studied as a potential biomarker of disease and cancer, with impacts on metabolism, cell cycle regulation, and pro-cancer state signaling. However these observational data have yet to be causally examined For example, neither perturbation of the key mA writers and , nor the mA readers and have been thoroughly mechanistically characterized as they have been .

Subcutaneous immunoglobulins (SCIG) for chronic inflammatory demyelinating polyneuropathy (CIDP): A comprehensive systematic review of clinical studies and meta-analysis.

Background: Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) presents significant treatment challenges due to its chronic nature, varied clinical presentations, and rarity. Subcutaneous immunoglobulin (SCIG) has emerged as a maintenance therapy, offering potential advantages in administration and patient experience over the previously recognized intravenous immunoglobulin (IVIG).

Methods: We included all clinical studies involving CIDP patients treated with SCIG from eleven databases up to March 2024.

Gross anatomy of vascular supply and drainage of mammary fat pads in mice models.

This work extensively studied the vasculature of mice mammary fat pads (BALB/c and C57BL/6) with special reference to haematogenous drainage routes. Mammary fat pads were five pairs (first cervical, second and third thoracic, fourth abdominal and fifth inguinal), bilaterally symmetrical, extending laterally and continuously with the subcutaneous fascia. The superficial cervical artery and vein primarily accomplished the blood vasculature of the first mammary fat pad, while the lateral thoracic and external thoracic arteries and veins supplied the second and third mammary fat pads.

Development of a dual channel detection system for pan-genotypic simultaneous quantification of hepatitis B and delta viruses.

Hepatitis B virus (HBV) infection remains a major public health problem and, in associated co-infection with hepatitis delta virus (HDV), causes the most severe viral hepatitis and accelerated liver disease progression. As a defective satellite RNA virus, HDV can only propagate in the presence of HBV infection, which makes HBV DNA and HDV RNA the standard biomarkers for monitoring the virological response upon antiviral therapy, in co-infected patients. Although assays have been described to quantify these viral nucleic acids in circulation independently, a method for monitoring both viruses simultaneously is not available, thus hampering characterization of their complex dynamic interactions.

It Takes a Village: An Interdisciplinary Approach to Preparing Internal Medicine Residents to Care for Patients at the Intersection of Women's Health, Gender-Affirming Care, and Health Disparities.

To create an interdisciplinary curriculum to teach key topics at the intersection of women's health, gender-affirming care, and health disparities to internal medicine (IM) residents. A core team of faculty from IM, Obstetrics and Gynecology, and Surgery partnered with faculty and fellows from other disciplines and with community experts to design and deliver the curriculum. The resulting curriculum consisted of themed half-day modules, each consisting of three to four inter-related topics, updated and repeated on an ∼3-year cycle.

Experiences of prognosis disclosure versus nondisclosure among family caregivers of persons with advanced cancer.

Caregiving in the South Asian context is often assumed by family automatically for the person with cancer (PWC). In this paper, we applied the disclosure decision-making model (DD-MM) to understand the motives behind cancer prognosis disclosure (or not) by caregivers to the PWC. Fifty caregivers participated in semi-structured interviews; and data were analyzed using Framework Approach.

Hepatitis delta virus RNA decline post-inoculation in human NTCP transgenic mice is biphasic.

Chronic infection with hepatitis B and delta viruses (HDV) is the most serious form of viral hepatitis due to more severe manifestations of an accelerated progression to liver fibrosis, cirrhosis, and hepatocellular carcinoma. We characterized early HDV kinetics post-inoculation and incorporated mathematical modeling to provide insights into host-HDV dynamics. We analyzed HDV RNA serum viremia in 192 immunocompetent (C57BL/6) and immunodeficient (NRG) mice that did or did not transgenically express the HDV receptor-human sodium taurocholate co-transporting polypeptide (hNTCP).

COVID-19 testing protocols to guide duration of isolation: a cost-effectiveness analysis.

Background: The Omicron variant of SARS-CoV-2 led to a steep rise in transmissions, and emerging variants continue to influence case rates across the US. As public tolerance for isolation abated, CDC guidance on duration of at-home isolation of COVID-19 cases was shortened to five days if no symptoms, with no laboratory test requirement, despite more cautious approaches advocated by other federal experts.

Methods: We conducted a decision tree analysis of alternative protocols for ending COVID-19 isolation, estimating net costs (direct and productivity), secondary infections, and incremental cost-effectiveness ratios.

Structural features stabilized by divalent cation coordination within hepatitis E virus ORF1 are critical for viral replication.

Hepatitis E virus (HEV) is an RNA virus responsible for over 20 million infections annually. HEV's open reading frame (ORF)1 polyprotein is essential for genome replication, though it is unknown how the different subdomains function within a structural context. Our data show that ORF1 operates as a multifunctional protein, which is not subject to proteolytic processing.

Hepatitis delta virus RNA decline post inoculation in human NTCP transgenic mice is biphasic.

Background And Aims: Chronic infection with hepatitis B and hepatitis delta viruses (HDV) is considered the most serious form of viral hepatitis due to more severe manifestations of and accelerated progression to liver fibrosis, cirrhosis, and hepatocellular carcinoma. There is no FDA-approved treatment for HDV and current interferon-alpha treatment is suboptimal. We characterized early HDV kinetics post inoculation and incorporated mathematical modeling to provide insights into host-HDV dynamics.

COVID-19 Testing Strategies for K-12 Schools in California: A Cost-Effectiveness Analysis.

Public health officials must provide guidance on operating schools safely during the COVID-19 pandemic. Using data from April-December 2021, we conducted a cost-effectiveness analysis to assess six screening strategies for schools using SARS-CoV-2 antigen and PCR tests and varying screening frequencies for 1000 individuals. We estimated secondary infections averted, quality-adjusted life years (QALYs), cost per QALY gained, and unnecessary school days missed per infection averted.

Indirect COVID-19 health effects and potential mitigating interventions: Cost-effectiveness framework.

Background: The COVID-19 pandemic led to important indirect health and social harms in addition to deaths and morbidity due to SARS-CoV-2 infection. These indirect impacts, such as increased depression and substance abuse, can have persistent effects over the life course. Estimated health and cost outcomes of such conditions and mitigation strategies may guide public health responses.

Modeling of overdose and naloxone distribution in the setting of fentanyl compared to heroin.

Background: Fentanyl has replaced most other non-prescribed opioids in much of North America. There is controversy over whether a hypothetical reduced efficacy of naloxone in reversing fentanyl is a major contributor to the coincident rising overdose mortality.

Methods: We modified an existing Markov decision analytic model of heroin overdose and naloxone distribution to account for known risks of fentanyl by adjusting overdose risk, the likelihood of death in the event of overdose, and the proportion of cases in which available naloxone was administered in time to prevent death.

Cost-effectiveness of antigen testing for ending COVID-19 isolation.

Background: The Omicron variant of SARS-CoV-2 led to a steep rise in transmissions. Recently, as public tolerance for isolation abated, CDC guidance on duration of at-home isolation of COVID-19 cases was shortened to five days if no symptoms, with no lab test requirement, despite more cautious approaches advocated by other federal experts.

Methods: We conducted a decision tree analysis of alternative protocols for ending COVID-19 isolation, estimating net costs (direct and productivity), secondary infections, and incremental cost-effectiveness ratios.

Optimal strategies to screen health care workers for COVID-19 in the US: a cost-effectiveness analysis.

Background: Transmission of SARS-CoV-2 in health care facilities poses a challenge against pandemic control. Health care workers (HCWs) have frequent and high-risk interactions with COVID-19 patients. We undertook a cost-effectiveness analysis to determine optimal testing strategies for screening HCWs to inform strategic decision-making in health care settings.
