Using minimally invasive tissue sampling (MITS) and Determination of Cause of Death (DeCoDe) to establish etiologies of community respiratory deaths among Zambian infants and children.

In low-to-middle income countries, acute lower respiratory infection (ALRI) remains the leading infectious cause of death among infants and children under 5 years old. Case-control studies based on upper respiratory sampling have informed current understandings of ALRI etiologies; in contrast, minimally-invasive tissue sampling (MITS) offers a method of directly interrogating lower respiratory tract pathogens to establish etiologic distributions. This study performed in the post-mortem setting used MITS and a Determination of Cause of Death (DeCoDe) panel to elucidate causes of fatal pneumonia in the community in Lusaka, Zambia.

The Microbiology, Management and Outcomes of Native Joint Septic Arthritis of the Hand in Adults of Southeast Queensland.

Native joint septic arthritis (NJSA) of the hand is poorly studied. Management guidelines are extrapolated from large joint infections despite differences in epidemiology, anatomy and aetiology. Limited evidence suggests shorter courses of antibiotics can achieve outcomes comparable to longer courses.

Solving Allen-Cahn equations with periodic and nonperiodic boundary conditions using mimetic finite-difference operators.

In this paper, we investigate and implement a numerical method that is based on the mimetic finite difference operator in order to solve the nonlinear Allen-Cahn equation with periodic and non-periodic boundary conditions. In addition, we also analyze the performance of this mimetic-based method by using the classical heat equation with a variety of boundary conditions. We assess the performance of the mimetic-based numerical method by comparing the errors of its solutions with those obtained by a classical finite difference method and the pdepde built-in Matlab function.

Sensory Entrained TMS (seTMS) enhances motor cortex excitability.

Transcranial magnetic stimulation (TMS) applied to the motor cortex has revolutionized the study of motor physiology in humans. Despite this, TMS-evoked electrophysiological responses show significant variability, due in part to inconsistencies between TMS pulse timing and ongoing brain oscillations. Variable responses to TMS limit mechanistic insights and clinical efficacy, necessitating the development of methods to precisely coordinate the timing of TMS pulses to the phase of relevant oscillatory activity.

Young people's lived sexual and reproductive health citizenship: participation and power of youth in Malawi.

This qualitative, focused critical ethnographic study explores how young people's 'lived SRH citizenship' and their active roles realising their sexual and reproductive health (SRH) and rights, shape their agency and participation in decision-making in Malawi. Informed by postcolonial feminist and difference-centred citizenship theories, our findings reveal that age-based power differentials, systems of gerontocracy and a culture of adultism impede bona fide youth involvement in SRH policymaking, making young citizens' participation more of an illusion than reality. Although democratisation and decentralisation aim to promote youth engagement, SRH policy spaces/processes lack institutionalised processes for integrating youth and remain dominated by donors and government.

Interconnected influence: Unraveling purdue pharmaceutical's role in the global response to the opioid crisis.

Background: The global pharmaceutical industry has a long history of prioritizing profits over public health through widespread practices such as price gouging, deceptive marketing, and fraud. A prominent example of this issue is the mislabeling and mass-marketing of OxyContin by Purdue Pharmaceuticals (Purdue) that catalyzed the opioid crises in and beyond the United States.

Methods: Guided by Actor-Network Theory, this case study employs Visual Network Analysis to map the actors-networks involved in responding to the harms caused by Purdue.

Marked variation in disease acuity and outcomes on the liver transplant waiting list by sociodemographic characteristics.

Understanding the association of social determinants of health with liver transplant listing and waitlist outcomes can inform health care policy and interventions aimed at improving access to care. We analyzed the Scientific Registry of Transplant Recipients database merged with the Social Deprivation Index (SDI) to evaluate if the area of residence is associated with the Model for End-Stage Liver Disease incorporating sodium (MELD-Na) at the time of waitlist placement and outcomes following waitlisting, and if this varied based on sociodemographic variables. Compared to candidates residing in areas of low SDI, those residing in areas of high SDI (most socioeconomic disadvantage) had 11% higher adjusted likelihood (aOR [95% CI] = 1.

Real-time optimization to enhance noninvasive cortical excitability assessment in the human dorsolateral prefrontal cortex.

Objective: We currently lack a robust noninvasive method to measure prefrontal excitability in humans. Concurrent TMS and EEG in the prefrontal cortex is usually confounded by artifacts. Here we asked if real-time optimization could reduce artifacts and enhance a TMS-EEG measure of left prefrontal excitability.

Experiences of child sex trafficking identification among Ontario pediatric emergency department healthcare providers: A qualitative study.

Background And Objective: More than 60 % of people exposed to sex trafficking access hospital emergency departments (ED), making the ED a critical setting for child sex trafficking identification. Children exposed to sex trafficking (CEST) do not always recognize that they are being exploited. With many ED leaders confirming that there are no formal processes or assessment tools to screen for human trafficking in EDs, it is especially challenging for healthcare providers to identify CEST.

Socioeconomic deprivation is associated with worse patient and graft survival following adult liver transplantation.

The impact of social determinants of health on adult liver transplant recipient outcomes is not clear at a national level. Further understanding of the impact of social determinants of health on patient outcomes can inform effective, equitable health care delivery. Unadjusted and multivariable models were used to analyze the Scientific Registry of Transplant Recipients to evaluate the association between the Social Deprivation Index (SDI) based on the liver transplant recipient's residential location and patient and graft survival.

Single-test syphilis serology: A case of not seeing the forest for the trees.

Introduction: There have been few empirical studies for diagnostic test accuracy of syphilis using a sequence of rapid tests in populations with low prevalence of syphilis such as pregnant women. This analysis describes syphilis test positivity frequency among pregnant women at an antenatal clinic in Zambia using a reverse-sequence testing algorithm for antenatal syphilis screening.

Methods: Between August 2019 and May 2023, we recruited 1510 pregnant women from a peri-urban hospital in Lusaka, Zambia.

Short-Term Cannabidiol with Δ-9-Tetrahydrocannabinol in Parkinson's Disease: A Randomized Trial.

Background: Cannabis use is frequent in Parkinson's disease (PD), despite inadequate evidence of benefits and risks.

Objective: The aim is to study short-term efficacy and tolerability of relatively high cannabidiol (CBD)/low Δ-9-tetrahydrocannabinol (THC) to provide preliminary data for a longer trial.

Methods: Persons with PD with ≥20 on motor Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) who had negative cannabis testing took cannabis extract (National Institute of Drug Abuse) oral sesame oil solution for 2 weeks, increasing to final dose of 2.

Cumulated time to chart closure: a novel electronic health record-derived metric associated with clinician burnout.

Objective: We sought to determine whether average cumulated time to chart closure (CTCC), a novel construct to measure clinician workload burden, and electronic health record (EHR) measures were associated with a validated measure of burnout.

Materials And Methods: Physicians at a large academic institution participated in a well-being survey that was linked to their EHR use data. CTCC was defined as the average time from the start of patient encounters to chart closure over a set of encounters.

African American race does not confer an increased risk of clinical events in patients with primary sclerosing cholangitis.

Background: The natural history of primary sclerosing cholangitis (PSC) among African Americans (AA) is not well understood.

Methods: Transplant-free survival and hepatic decompensation-free survival were assessed using a retrospective research registry from 16 centers throughout North America. Patients with PSC alive without liver transplantation after 2008 were included.

Interdependent Determinants of Health and Death? Examining the Linkages between Health Equity, Human Rights, and Democracy during COVID-19.

Background: The COVID-19 pandemic has been characterised by health inequities in differential rates of COVID-19-related morbidity and mortality and differential access to essential COVID-19-related health care interventions such as vaccines. Inequities through the pandemic have deeply illuminated the interdependence between health inequities, human rights, and democratic leadership and the imperative to delve more deeply into these key determinants of health, illness, and death.

Methods: In this paper, we consider what COVID-19 suggests we should be learning about the relationships between democracy, human rights, and health equity.

Can we move beyond vaccine apartheid? Examining the determinants of the COVID-19 vaccine gap.

While global health leaders call disparities in access to COVID-19 vaccines an 'apartheid,' this gap is not the first such disparity. The recurrence of these gaps in low and middle-income countries and especially in Africa, raises questions about their determinants and about the persistent failures of global health institutions to remediate them. We interrogate these determinants and questions by examining: (1) the distribution of COVID-19 vaccines; (2) primary determinants of vaccine access including availability and affordability; (3) factors affecting availability (hoarding, COVAX, and manufacturing capacity); and (4) factors affecting affordability (pricing, intellectual property rights (IPR), the TRIPS waiver and a potential pandemic treaty).

Promoting children's rights to health and well-being in the United States.

The United States has a highly sophisticated pediatric healthcare system and spends more than any other country per capita on children's healthcare. However, not all children have access to needed and affordable health care and the life expectancy and health outcomes of children in the country are worse than in any other industrialized nation. These nations typically offer universal healthcare for children as part of a robust recognition of a children's rights framework.

Safety, tolerability, and efficacy of maralixibat in adults with primary sclerosing cholangitis: Open-label pilot study.

Background: Primary sclerosing cholangitis (PSC) is frequently associated with pruritus, which significantly impairs quality of life. Maralixibat is a selective ileal bile acid transporter (IBAT) inhibitor that lowers circulating bile acid (BA) levels and reduces pruritus in cholestatic liver diseases. This is the first proof-of-concept study of IBAT inhibition in PSC.

COVID-19 vaccine equity and the right to health for displaced Venezuelans in Latin America.

Given the magnitude of Venezuelan displacement in Latin America, there is a need to assess how migrants were, and will continue to be, addressed in COVID-19 vaccination policies. To explore migration status as a dimension of vaccine equity in Latin America and in relation to international human rights, we assessed national vaccination plans, peer-reviewed, and gray literature published between January 2020 and June 2021. Three key rights-related concerns were found to restrict the health rights of migrants in the region: 1) lack of prioritization of migrants in vaccine distribution; 2) onerous documentation requirements to be eligible for COVID-19 vaccination; and (3) how pervasive anti-migrant discrimination limited equitable health care access.

Unmasking legislative constraints: An institutional ethnography of linkage and engagement in HIV healthcare for African, Caribbean, and Black people in Ontario, Canada.

The Human Immunodeficiency Virus (HIV) epidemic significantly impacts African, Caribbean, and Black (ACB) immigrants in Canada. Health scholarship has revealed striking injustices within Canada's public healthcare system that restrict access to healthcare and violate the human rights of ACB immigrants living with HIV who are marginalized. We conducted an institutional ethnography to comprehensively understand how HIV healthcare in Ontario is organized and experienced by ACB immigrants, focusing on unjust and discriminatory legislative frameworks and institutional practices regulating access to publicly funded healthcare resources and services.

Impact of alcohol use disorder severity on human immunodeficiency virus (HIV) viral suppression and CD4 count in three international cohorts of people with HIV.

Background: Alcohol use has been linked to worse human immunodeficiency virus (HIV) immunologic/virologic outcomes, yet few studies have explored the effects of alcohol use disorder (AUD). This study assessed whether AUD severity is associated with HIV viral suppression and CD4 count in the three cohorts of the Uganda Russia Boston Alcohol Network for Alcohol Research Collaboration on HIV/AIDS (URBAN ARCH) Consortium.

Methods: People with HIV (PWH) in Uganda (n = 301), Russia (n = 400), and Boston (n = 251), selected in-part based on their alcohol use, were included in analyses.

Structural violence and the uncertainty of viral undetectability for African, Caribbean and Black people living with HIV in Canada: an institutional ethnography.

Biomedical advances in healthcare and antiretroviral treatment or therapy (ART) have transformed HIV/AIDS from a death sentence to a manageable chronic disease. Studies demonstrate that people living with HIV who adhere to antiretroviral therapy can achieve viral suppression or undetectability, which is fundamental for optimizing health outcomes, decreasing HIV-related mortality and morbidity, and preventing HIV transmission. African, Caribbean, and Black (ACB) communities in Canada remain structurally disadvantaged and bear a disproportionate burden of HIV despite biomedical advancements in HIV treatment and prevention.
