Research ethics review during the COVID-19 pandemic: An international study.

Research ethics review committees (ERCs) worldwide faced daunting challenges during the COVID-19 pandemic. There was a need to balance rapid turnaround with rigorous evaluation of high-risk research protocols in the context of considerable uncertainty. This study explored the experiences and performance of ERCs during the pandemic.

Identifying priority challenges and solutions for COVID-19 vaccine delivery in low- and middle-income countries: A modified Delphi study.

Background: The rapid implementation of global COVID-19 vaccination programs has surfaced many challenges and inequities, particularly in low- and middle-income countries (LMICs). However, there continues to be a lack of consensus on which challenges are global priorities for action, and how to best respond to them. This study uses consensus-based methods to identify and rank the most important challenges and solutions for implementation of COVID-19 vaccination programs in LMICs.

Global inequity creates local insufficiency: A qualitative study of COVID-19 vaccine implementation challenges in low-and-middle-income countries.

Introduction: The COVID-19 pandemic has amplified pre-existing challenges to health promotion and care across the world, and particularly in low- and middle-income countries (LMICs). This qualitative study draws on data from a panel of immunisation experts and uses a novel framework of vaccine delivery domains to explore perspectives from those who live and work in these settings on the challenges to implementing COVID-19 vaccine programs in LMICs.

Methods: We conducted a thematic content analysis of 96 participant free text replies to questions from Round I of a three-round Delphi consensus study amongst global experts on COVID-19 vaccine implementation.

R&D during public health emergencies: the value(s) of trust, governance and collaboration.

In January 2021, Dr Tedros Adhanom Ghebreyesus, director-general of the WHO, warned that the world was 'on the brink of a catastrophic moral failure [that] will be paid with lives and livelihoods in the world's poorest countries'. We are now past the brink. Many high-income countries have vaccinated their populations (which, in some cases, includes third and even fourth doses) and are loosening public health and social measures, while low-income and middle-income countries are struggling to secure enough supply of vaccines to administer first doses.

Mal/adaptations: A qualitative evidence synthesis of opioid agonist therapy during major disruptions.

Background: Opioid agonist therapy (OAT) has been severely disrupted by the COVID-19 pandemic. The risks of opioid withdrawal, overdose, and diversion have increased, so there is an urgent need to adapt OAT to best support people who use drugs (PWUD). This review examines the views and experiences of PWUD, health care providers, and health system administrators on OAT during major disruptions to medical care to inform appropriate health system responses during the current pandemic and beyond.

Beyond harm-producing versus harm-reducing: A qualitative meta-synthesis of people who use drugs' perspectives of and experiences with the extramedical use and diversion of buprenorphine.

Introduction: This review synthesizes the literature on the perspectives and experiences of people who use drugs to better understand motivations and behaviors related to the extramedical use and diversion of buprenorphine. Given the particular social construction of buprenorphine against methadone, and the centrality of concerns around extramedical use in delivering opioid agonist therapies, a focus on extramedical buprenorphine use can provide an important lens through which to analyze treatment for opioid use disorder. This review is framed within persistent tensions between potential harm-producing versus harm-reducing effects of extramedical use that have long been described for opioid agonist therapies.

Molecules linked to Ras signaling as therapeutic targets in cardiac pathologies.

The Ras family of small Guanosine Triphosphate (GTP)-binding proteins (G proteins) represents one of the main components of intracellular signal transduction required for normal cardiac growth, but is also critically involved in the development of cardiac hypertrophy and heart failure. The present review provides an update on the role of the H-, K- and N-Ras genes and their related pathways in cardiac diseases. We focus on cardiac hypertrophy and heart failure, where Ras has been studied the most.

Evaluations of Continuing Health Provider Education Focused on Opioid Prescribing: A Scoping Review.

Purpose: Continuing health provider education (HPE) is an important intervention supported by health policy to counter the opioid epidemic; knowledge regarding appropriate program design and evaluation is lacking. The authors aim to provide a comprehensive understanding of evaluations of opioid-related continuing HPE programs and their appropriateness as interventions to improve population health.

Method: In January 2020, the authors conducted a systematic search of 7 databases, seeking studies of HPE programs on opioid analgesic prescribing and overdose prevention.

The ethical, social, and cultural dimensions of screening for mental health in children and adolescents of the developing world.

Despite their burden and high prevalence, mental health disorders of children and adolescents remain neglected in many parts of the world. In developing countries, where half of the population is younger than 18 years old, one of every five children and adolescents is estimated to suffer from a mental health disorder. It is then essential to detect these conditions through screening in a timely and accurate manner.

Ethical and scientific issues of nanotechnology in the workplace.

In the absence of scientific clarity about the potential health effects of occupational exposure to nanoparticles, a need exists for guidance in decision making about hazards, risks, and controls. An identification of the ethical issues involved may be useful to decision makers, particularly employers, workers, investors, and health authorities. Because the goal of occupational safety and health is the prevention of disease in workers, the situations that have ethical implications that most affect workers have been identified.
