HIV infection.

The AIDS epidemic has been a global public health issue for more than 40 years and has resulted in ~40 million deaths. AIDS is caused by the retrovirus, HIV-1, which is transmitted via body fluids and secretions. After infection, the virus invades host cells by attaching to CD4 receptors and thereafter one of two major chemokine coreceptors, CCR5 or CXCR4, destroying the host cell, most often a T lymphocyte, as it replicates.

Application of group model building in implementation research: A systematic review of the public health and healthcare literature.

Background: Group model building is a process of engaging stakeholders in a participatory modeling process to elicit their perceptions of a problem and explore concepts regarding the origin, contributing factors, and potential solutions or interventions to a complex issue. Recently, it has emerged as a novel method for tackling complex, long-standing public health issues that traditional intervention models and frameworks cannot fully address. However, the extent to which group model building has resulted in the adoption of evidence-based practices, interventions, and policies for public health remains largely unstudied.

Impact of the First Year of the COVID-19 on Unmet Healthcare Need among New York City Adults: a Universal Healthcare Experiment.

We examined the impact of the first year of the COVID-19 pandemic on unmet healthcare need among New Yorkers and potential differences by race/ethnicity and health insurance. Data from the Community Health Survey, collected in 2018, 2019, and 2020, were merged to compare unmet healthcare need within the past 12 months during the pandemic versus the 2 years prior to 2020. Univariate and multivariable logistic regression models evaluated change in unmet healthcare need overall, and we assessed whether race/ethnicity or health insurance status modified the association.

Hepatitis C virus care cascade among people who inject drugs in puerto rico: Minimal HCV treatment and substantial barriers to HCV care.

Background: People who inject drugs (PWID) in Puerto Rico are disproportionately affected by the hepatitis C virus (HCV) epidemic. However, there is a scarcity of data on the HCV care cascade among PWID in Puerto Rico. This study aims to describe the HCV cascade of care among PWID in Puerto Rico, identify gaps, and explore barriers to HCV care.

A global action agenda for turning the tide on fatty liver disease.

Background And Aims: Fatty liver disease is a major public health threat due to its very high prevalence and related morbidity and mortality. Focused and dedicated interventions are urgently needed to target disease prevention, treatment, and care.

Approach And Results: We developed an aligned, prioritized action agenda for the global fatty liver disease community of practice.

"Treated like a Human Being": perspectives of people who inject drugs attending low-threshold HCV treatment at a syringe service program in New York City.

Background: Hepatitis C virus (HCV) treatment can effectively cure HCV among people who inject drugs (PWID). Perspectives of PWID treated in innovative models can reveal program features that address barriers to treatment, and guide implementation of similar models.

Methods: We interviewed 29 participants in the intervention arm of a randomized trial.

Identifying opportunities for collective action around community nutrition programming through participatory systems science.

Purpose: To apply principles of group model building (GMB), a participatory systems science approach, to identify barriers and opportunities for collective impact around nutrition programming to reduce cancer risk for immigrant communities in an urban environment.

Methods: We convened four in-person workshops applying GMB with nine community partners to generate causal loop diagrams (CLDs)-a visual representation of hypothesized causal relationships between variables and feedback structures within a system. GMB workshops prompted participants to collaboratively identify programmatic goals and challenges related to (1) community gardening, (2) nutrition education, (3) food assistance programs, and (4) community-supported agriculture.

The Need for Systems Approaches for Precision Communications in Public Health.

A major challenge in communicating health-related information is the involvement of multiple complex systems from the creation of the information to the sources and channels of dispersion to the information users themselves. To date, public health communications approaches have often not adequately accounted for the complexities of these systems to the degree necessary to have maximum impact. The virality of COVID-19 misinformation and disinformation has brought to light the need to consider these system complexities more extensively.

Statement: Multisectoral actions to build trust at the local and community level to promote vaccine acceptance.

On 12 September 2022, attendees of the 16th Vaccine Congress in Riva del Garda, Italy were invited to attend a roundtable session entitled multi-sectoral actions to build trust at the local and community level to promote vaccine acceptance to participate in a discussion aimed at defining strategies and recommendations to support efforts that build community vaccine confidence. Presenters from the Vaccine Confidence Project and the New York Vaccine Literacy Campaign shared research and data point on the current state of vaccine confidence worldwide as well as global examples of "success stories" to prompt discussion. The group's key recommendations include prioritizing multi-sectoral responses and trust-building through policy and legislation, engaging with trusted local stakeholders, improving convenience, combating misinformation and empowering healthcare professionals to improve vaccine confidence.

A global research priority agenda to advance public health responses to fatty liver disease.

Background & Aims: An estimated 38% of adults worldwide have non-alcoholic fatty liver disease (NAFLD). From individual impacts to widespread public health and economic consequences, the implications of this disease are profound. This study aimed to develop an aligned, prioritised fatty liver disease research agenda for the global health community.

A virtual breakthrough series collaborative to support deprescribing interventions across Veterans Affairs healthcare settings.

Background: Virtual collaborative models are a practical way to implement a supportive environment for multi-team learning. In this project, we aimed to describe the processes and outcomes of a virtual deprescribing collaborative that facilitated implementation of deprescribing interventions around the country.

Methods: Two successive cohorts comprised of multidisciplinary teams from geographically diverse veterans affairs (VA) sites were selected via an application process to participate in a virtual deprescribing collaborative.

Experiences of police-related stress among a U.S. national cohort of gay and bisexual men.

Marginalized groups (including people of Color and sexual minorities) have been over-policed and specifically targeted based on their race/ethnicity and identity. The deleterious effects of over-policing marginalized groups include overrepresentation in the carceral system, experiencing higher rates of violence from police, and extend to affect mental health and stress levels. This study examines police-related stress among a U.

Low responsiveness of peripheral lymphocytes in extraparenchymal neurocysticercosis.

Background: The morbidity and mortality of extraparenchymal neurocysticercosis (EP-NC) remain high and effectiveness of current medical treatment is suboptimal. Various factors have been implicated in the severity of EP-NC and in the poor response to treatment, but the possible role of host immune and endocrine systems has not yet been examined thoroughly.

Methodology/principal Findings: 42 participants with EP-NC before receiving standard treatment and 25 healthy controls were included in the study.

Combined COVID-19 vaccination and hepatitis C virus screening intervention in marginalised populations in Spain.

Background: COVID-19 has hindered hepatitis C virus (HCV) and HIV screening, particularly in marginalised groups, who have some of the highest rates of these conditions and lowest rates of COVID-19 vaccination. We assessed the acceptability of combining HCV testing with COVID-19 vaccination in a centre for addiction services (CAS) in Barcelona and a mobile testing unit (MTU) in Madrid, Spain.

Methods: From 28/09/2021 to 30/06/2022, 187 adults from marginalised populations were offered HCV antibody (Ab) testing along with COVID-19 vaccination.

Supporting US healthcare providers for successful vaccine communication.

Background: While many healthcare providers (HCPs) have navigated patients' vaccine concerns and questions prior to the rollout of the COVID-19 vaccines, sentiments surrounding the COVID-19 vaccines have presented new and distinct challenges.

Objective: To understand the provider experience of counseling patients about COVID-19 vaccinations, aspects of the pandemic environment that impacted vaccine trust, and communication strategies providers found supportive of patient vaccine education.

Methods: 7 focus groups of healthcare providers were conducted and recorded during December 2021 and January 2022, at the height of the Omicron wave in the United States.

Research Priorities for Precision Medicine in NAFLD.

NAFLD is a multisystem condition and the leading cause of chronic liver disease globally. There are no approved NAFLD-specific dugs. To advance in the prevention and treatment of NAFLD, there is a clear need to better understand the pathophysiology and genetic and environmental risk factors, identify subphenotypes, and develop personalized and precision medicine.

Physicians' Use of Digital Health Interventions in the Management of Nonalcoholic Fatty Liver Disease.

Globally, the use of digital health interventions (DHIs) is expanding, along with growing scientific evidence of their effectiveness. Given the high and increasing prevalence of noncommunicable liver disease, we surveyed 295 physicians across Spain about their knowledge, beliefs, attitudes, practices, and access with regard to DHIs for patient care and in particular for liver diseases, including nonalcoholic fatty liver disease and nonalcoholic steatohepatitis. Physicians reported high familiarity with DHIs, although most had not recommended them in patient care.
