The Molecular Basis of the Intrinsic and Acquired Resistance to Azole Antifungals in .

is intrinsically resistant to the widely used antifungal fluconazole, and therapeutic failure can result from acquired resistance to voriconazole, the primary treatment for invasive aspergillosis. The molecular basis of substrate specificity and innate and acquired resistance of to azole drugs were addressed using crystal structures, molecular models, and expression in of the sterol 14α-demethylase isoforms AfCYP51A and AfCYP51B targeted by azole drugs, together with their cognate reductase AfCPRA2 and AfERG6 (sterol 24-C-methyltransferase). As predicted by molecular modelling, functional expression of CYP51A and B required eburicol and not lanosterol.

Optimal implementation of an Ontario nirsevimab program for respiratory syncytial virus (RSV) prophylaxis: Recommendations from a provincial RSV expert panel.

In June 2024, a group of 12 experts in the respiratory syncytial virus (RSV) field representing a cross-section of healthcare provider types who treat and care for pregnant individuals and infants, assembled to discuss the implementation of a broad infant prophylaxis program with nirsevimab in Ontario. To gain insight on potential best practices founded on the experiences of other jurisdictions, the meeting comprised a review of the 2023/2024 RSV season programs in Spain, France, and the United States that implemented nirsevimab prophylaxis. The impact of nirsevimab in reducing severe RSV disease among infants during the first RSV season was assessed including the implications on hospital resources and healthcare system costs.

Anxiety, anhedonia, and related food consumption in Israelis populations:An online cross-sectional study two years since the outbreak of COVID-19.

Background: The COVID-19 pandemic has significantly impacted daily life. Beyond severe health and economic consequences, psychological consequences have surfaced that require in-depth research to understand the pandemic's effects on mental health. Aims: This study aimed to evaluate the association between anxiety levels and anhedonia with food consumption patterns and changes in body weight over the two years since the COVID-19 outbreak in Israel.

COVID-19 Therapeutics: Use, Mechanism of Action, and Toxicity (Vaccines, Monoclonal Antibodies, and Immunotherapeutics).

SARS-CoV-2 emerged in December 2019 and led to the COVID-19 pandemic. Efforts to develop therapeutics have led to innovations such as mRNA vaccines and oral antivirals. Here we provide a narrative review of the biologic therapeutics used or proposed to treat COVID-19 during the last 3 years.
