Environmental exposures and the risk of hepatocellular carcinoma.

The global epidemiology of HCC is shifting due to changes in both established and emerging risk factors. This transformation is marked by an emerging prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes, alongside traditional risks such as viral hepatitis (HBV and HCV), and exposure to chemical agents like aflatoxin, alcohol, tobacco, and air pollution. This review examines how environmental exposures and evolving liver pathology, exacerbated by lifestyle and metabolic conditions, are contributing to the rising worldwide incidence of HCC.

Hispanic survival paradox: a systematic review of short-term hospital readmissions among Hispanic kidney transplant recipients in the United States.

Purpose Of Review: The epidemiologic phenomenon known as the "Hispanic paradox" postulates that Hispanic/Latino Americans generally tend to live longer than other racial/ethnic communities, despite facing many socioeconomic disadvantages and other healthcare barriers. Whether this phenomenon is relevant among kidney transplantation (KT) recipients remains unclear. To investigate the possibility of a Hispanic mortality advantage, we conducted a systematic review of the published literature comparing short-term KT outcomes (first 12-months) for US Hispanic versus non-Hispanic White KT recipients.

The response of health systems to the needs of migrants and refugees in the COVID-19 pandemic: a comparative case study between Mexico, Colombia and Peru.

Background: Protecting the health of migrants and refugees during the pandemic was a significant challenge in the Latin American region. We aimed to describe and contrast the response of the health systems of Mexico, Colombia and Perú to migrants' and refugees' health needs during the COVID-19 pandemic, and to situate the response in the context of the migration and health policies of each country.

Methods: We conducted case studies of the three countries.

The Association of Spousal Relationship Quality and Social Support With Maternal-Infant Bonding: Moderating Roles of Maternal Age and Paternal Occupation.

This study examined associations between spousal relationship quality and social support with mother-infant bonding among women in Rawalpindi, Pakistan (Intervention Arm: n = 352, M = 25.1, SD = 4.7; Control Arm: n = 358, M = 25.

Diffuse Axonal and Vascular Pathology in the Gyrencephalic Brain after High-Energy Blunt Injury: Clinicopathological Correlations Involving the Brainstem.

Traumatic brain injury (TBI) after high-energy, behind helmet blunt trauma (BHBT) is an important but poorly understood clinical entity often associated with apnea and death in humans. In this study, we use a swine model of high-energy BHBT to characterize key neuropathologies and their association with acute respiratory decompensation. Animals with either stable or critical vital signs were euthanized within 4 h after injury for neuropathological assessment, with emphasis on axonal and vascular pathologies in the brainstem.

Evaluation of the Performance of Portable Hemoglobinometers at Measuring Hemoglobin and Detecting Anemia in a Periurban Pediatric Population in Lima, Peru.

As many as one in three people worldwide have anemia, with young children at increased risk of both disease and complications. In settings without clinical laboratories, portable hemoglobinometers serve important roles in diagnosing anemia and estimating prevalence. Here, we assess the validity of two such point-of-care devices-the HemoCue Hb201 and the HemoCue Hb301-relative to the international reference standard, the cyanmethemoglobin method.

The redox sensor KEAP1 facilitates adaptation of T cells to chronic antigen stimulation by preventing hyperactivation.

During persistent antigen stimulation, exhausted CD8 T cells are continuously replenished by self-renewing stem-like T cells. However, how CD8 T cells adapt to chronic stimulation remains unclear. Here, we show that persistent antigen stimulation primes chromatin for regulation by the redox-sensing KEAP1-NRF2 pathway.

The Plasmodium circumsporozoite protein.

The circumsporozoite protein (CSP) is one of the most studied proteins of the malaria parasite. It is the target of the only licensed malaria vaccines and is essential for sporozoite formation and infectivity. Yet, the mechanisms by which CSP functions and its interactions with other proteins are only beginning to be understood.

New Insights Into The Melanin Structure Of .

is a filamentous fungus with a global distribution, manifesting particularly higher prevalence in human-impacted environments. This organism is associated with a wide spectrum of human infections, especially in immunosuppressed individuals, for whom it causes severe and debilitating illnesses with high morbidity and mortality that are compounded by its pan-resistant profile with respect to antifungal drugs. Melanin is a ubiquitous pigment among fungi with a broad range of actions that include promoting fungal virulence.

Impacts of Parental Food Choice Values on Children's Restaurant Eating Behavior Among Regular Restaurant Consumers With Low Income: A Latent Class Analysis.

Objective: To identify subgroups of parents' food choice value systems and evaluate associations with restaurant eating behaviors of children.

Design: Cross-sectional survey.

Participants: Parents with low income and children aged 2-11 years who were frequent restaurant visitors before the coronavirus disease 2019 pandemic (n = 1,146).

Weighing risks and benefits in the presence of competing risks.

Purpose Of Review: When competing events occur, there are two main options for handling them analytically that invoke different assumptions: 1) censor person-time after a competing event (which is akin to assuming they could be prevented) to calculate a conditional risk; or 2) do not censor them (allow them to occur) to calculate an unconditional risk. The choice of estimand has implications when weighing the relative frequency of a beneficial outcome and an adverse outcome in a risk-benefit analysis.

Recent Findings: We review the assumptions and interpretations underlying the two main approaches to analyzing competing risks.

Sexual violence affecting female sex workers in Côte d'Ivoire: prevalence, context, and associated mental health and substance use outcomes.

Background: Female sex workers are disproportionately affected by sexual violence, which is associated with an increased risk of poor mental health outcomes, substance use, and decreased access to health resources. Understanding the pathways through which sexual violence impacts these outcomes can inform strategies that appropriately and effectively meet the health needs of sex workers.

Methods: This study investigated the prevalence of sexual violence among female sex workers in Côte d'Ivoire, and the relationship between sexual violence and adverse mental health and substance use outcomes.

Adapting the Social Norms Exploration Tool in the Democratic Republic of the Congo to Identify Social Norms for Behavior Change.

In the Democratic Republic of the Congo (DRC), male engagement, social norms, and social networks mitigate family planning behavior. We discuss the adaptation of the Social Norms Exploration Tool (SNET), which identifies relevant social norms and community members upholding these norms, to inform the development of family planning interventions in the DRC. The SNET provides activity tools and templates to guide users through the following steps: (1) plan and prepare, (2) identify reference groups, (3) explore social norms, (4) analyze results, and (5) apply findings.

The changing roles of scientific journals.

After centuries of relative stability, the scientific publishing world has undergone tremendous disruption and change during the first decades of the 21st century. The causes for disruption can be traced to the information revolution, which brought such benefits as rapid publication, greater connectivity, and ready access to large databases, along with less desirable practices including image manipulation, plagiarism, and other ethical transgressions. The information revolution has driven the proliferation of journals, expansion of for-profit academic publishing, and empowerment of the open-access movement, each of which has exerted new financial pressures on traditional publishing models.

Association between Left Ventricular Geometry, Systolic Ejection Time, and Estimated Glomerular Filtration Rate in Ambulatory Patients with Preserved Left Ventricular Ejection Fraction.

Introduction: Cardiac function is important to quantify for risk stratification. Although left ventricular ejection fraction (LVEF) is commonly used, and identifies patients with poor systolic function, other easily acquired measures of cardiac function are needed, particularly to stratify patients with relatively preserved LVEF. LV relative wall thickness (RWT) has been associated with adverse clinical outcomes in patients with preserved LVEF, but the clinical relevance of this observation is not known.

Estimates of actual and potential lives saved in the United States from the use of COVID-19 convalescent plasma.

In the Spring of 2020, the United States of America (USA) deployed COVID-19 convalescent plasma (CCP) to treat hospitalized patients. Over 500,000 patients were treated with CCP during the first year of the pandemic. In this study, we estimated the number of actual inpatient lives saved by CCP treatment in the United States of America based on CCP weekly use, weekly national mortality data, and CCP mortality reduction data from meta-analyses of randomized controlled trials and real-world data.

Society of Family Planning Clinical Recommendation: Induction of fetal asystole before abortion Jointly developed with the Society for Maternal-Fetal Medicine.

This document serves as a revision to the Society of Family Planning's 2010 guidelines, integrating literature on new techniques and research and addressing the clinical, medical, and sociolegal questions surrounding the induction of fetal asystole. Insufficient evidence exists to recommend routine induction of fetal asystole before previable medication and procedural abortion. However, at periviable gestations and after fetal viability, inducing fetal asystole before abortion prevents the infrequent but serious occurrence of unanticipated expulsion of a fetus with cardiorespiratory activity (Best Practice).
