Nitric oxide is a ubiquitous signaling radical that influences critical body functions. Its importance in the cardiovascular system and the innate immune response to bacterial and viral infections has been extensively investigated. The overproduction of NO is an early component of viral infections, including those affecting the respiratory tract. The production of high levels of NO is due to the overexpression of NO biosynthesis by inducible NO synthase (iNOS), which is involved in viral clearance. The development of NO-based antiviral therapies, particularly gaseous NO inhalation and NO-donors, has proven to be an excellent antiviral therapeutic strategy. The aim of this review is to systematically examine the multiple research studies that have been carried out to elucidate the role of NO in viral infections and to comprehensively describe the NO-based antiviral strategies that have been developed thus far. Particular attention has been paid to the potential mechanisms of NO and its clinical use in the prevention and therapy of COVID-19.

Importance: Blood culture (BC) use benchmarks in US hospitals have not been defined.
Objective: To characterize BC use in adult intensive care units (ICUs) and wards in US hospitals.
Design, Setting, And Participants: A retrospective cross-sectional study of BC use in adult medical ICUs, medical-surgical ICUs, medical wards, and medical-surgical wards from acute care hospitals from the 4 US geographic regions was conducted.

Importance: Recent studies have found an association between COVID-19 infection and deeper sedation in mechanically ventilated patients, raising concerns about the impact of the COVID-19 pandemic on pain, agitation, and delirium (PAD) management practices overall.
Objectives: This study aimed to assess differences in PAD management in patients without COVID-19 infection in pre- and peri-COVID-19 pandemic timeframes.
Design, Setting, And Participants: This was a single-center, retrospective, pre-/post-cohort analysis of mechanically ventilated adult patients without COVID-19 infection admitted to an ICU in Boston, MA.

Purpose: This narrative review addresses post-2020, specific, complex challenges for use of and adherence to pre-exposure prophylaxis (PrEP) for HIV prevention among out-of-treatment people who use drugs (PWUD) at syringe services programs (SSPs).
Recent Findings: The COVID-19 pandemic and its associated changes to the provision of healthcare have significantly impacted HIV prevention, especially for PWUD. Through a synthesis of literature and clinical experience, we (1) characterize the operational changes imposed by the pandemic on SSPs that shaped the current HIV prevention landscape; (2) describe three levels of current challenges for PWUD, including consumer attitudes, non-medical and medical provider attitudes, and structural and scalability barriers; (3) characterize current models for PrEP in SSPs; and (4) offer practical recommendations for HIV prevention in harm reduction programs.

Background: Sugarcane is cultivated globally and affected by more than 125 pathogens, which lead to various plant diseases. In recent years, high-throughput sequencing (HTS)-based genome analyses have been broadly adopted for the discovery of both characterized and un-characterized viruses from plant samples. In this study, the HTS data of sugarcane pooled sample retrieved from sequence read archive (SRA) were de novo re-assembled using CLC Genomic Workbench.

Background: The cognitive and behavioural changes that occur in around 50% of people with amyotrophic lateral sclerosis (ALS) may significantly affect people around them, contributing to heightened burden, anxiety, and depression. Despite existing evidence linking behavioural impairment to caregiver distress, the role of cognitive impairment remains less clear, with mixed findings on its impact.
Methods: This study assessed the influence of cognitive and behavioural impairments in people with ALS on the distress of their nominated informants.
