Clinical trials during public health emergencies of novel medical products such as therapeutics and vaccines in resource-limited settings are daunting due to the limited capacity for regulatory assessment. Regulating clinical trials during the Ebola outbreak in Sierra Leone required expedited evaluation to identify medical products that could be promptly introduced to combat the epidemic in the absence of approved treatment or prevention. This article explored the decisions taken by the Pharmacy Board of Sierra Leone through its Expert Committee on Medicine Safety and Clinical Trials regarding clinical trials oversight during the Ebola epidemic and the lessons learned.

Proponents of autism intervention and those of the neurodiversity movement often appear at odds, the former advocating for intensive treatments and the latter arguing that autism must be accepted as a form of diversity. The history of behavioral intervention has understandably outraged many in the Autistic community, though many still value supports focused on quality of life. This commentary argues that Naturalistic Developmental Behavioral Interventions (NDBIs) hold promise for bridging the gap between early intervention and the neurodiversity movement.

Monitoring antibiotic consumption is crucial to tackling antimicrobial resistance. However, currently there is no system in Sierra Leone for recording and reporting on antibiotic consumption. We therefore conducted a cross-sectional study to assess national antibiotic consumption expressed as defined daily dose (DDD) per 1000 inhabitants per day using all registered and imported antibiotics (categorized under the subgroup J01 under the anatomical and therapeutic classification (ATC) system) as a proxy.

The evolution of phage resistance poses an inevitable threat to the efficacy of phage therapy. The strategic selection of phage combinations that impose high genetic barriers to resistance and/or high compensatory fitness costs may mitigate this threat. However, for such a strategy to be effective, the evolution of phage resistance must be sufficiently constrained to be consistent.

Gay men, particularly middle aged and older men (over 40 years of age) experience a disproportionate burden of mental health issues compared to heterosexual men. Despite ample evidence that chronic exposure to structural and interpersonal discrimination negatively affect their mental health, little is known from gay men's perspectives how they understand mental health or their strategies to address their mental health concerns. This study's aim was to investigate how middle aged and older gay men experience their mental health and the mitigation strategies used to promote mental health.

Background: Many people with congenital heart disease (CHD) experience psychological distress related to medical complications and psychosocial issues related to the disease. Although studies show that social support and coping strategies are closely associated with psychological distress in people struggling with different chronic health challenges, very little is known about whether the same factors hold true for the psychological distress of people living with CHD.

Objective: The purpose of this study was to examine the relationships between types of social support, coping strategies, and psychological distress for individuals living with CHD.

The endophytic fungus Mortierella hyalina colonizes the roots of Arabidopsis thaliana and stimulates growth and biomass production of the aerial parts but not of roots. An exudate fraction from the fungus induces rapid and transient cytoplasmic Caelevation in the roots. The Ca response does not require the well-characterized (co)receptors BAK1, CERK1, and FLS2 for pathogen-associated molecular patterns, and the Ca channels GLR-2.
