We sought to determine if controlled, prospective clinical data validate the long-standing belief that intravenous (IV) antibiotic therapy is required for the full duration of treatment for 3 invasive bacterial infections: osteomyelitis, bacteremia, and infective endocarditis. ⋯ Numerous prospective, controlled investigations demonstrate that oral antibiotics are at least as effective, safer, and lead to shorter hospitalizations than IV-only therapy; no contrary data were identified. Treatment guidelines should be modified to indicate that oral therapy is appropriate for reasonably selected patients with osteomyelitis, bacteremia, and endocarditis.

Influenza increases morbidity and mortality in systemic lupus erythematosus (SLE) and lupus nephritis but is preventable through vaccination. This systematic review of PubMed, Embase, CENTRAL, WHO Clinical Trials, and ClinicalTrials.gov publications until August 2021 identified 45 reports (16,596 patients), including 8.5% with renal involvement or lupus nephritis: 9 studies (10,446 patients) on clinical effectiveness, 20 studies (1327 patients) on vaccine efficacy, 22 studies (1116 patients) on vaccine safety, 14 studies (4619 patients) on utilization rates, and 5 studies (3220 patients) on barriers. Pooled seroconversion rates ranged between 46% and 56%, while seroprotection rates ranged from 68% to 73% and were significantly associated with age and disease duration. ⋯ Disease activity scores did not change significantly after vaccination and reported flares were mild to moderate. Pooled current vaccination rate was 40.0% (95% confidence interval [CI]: 33.7%-46.5%) with significant heterogeneity and associated with the gross domestic product (P = .002) and disease duration (P = .001). Barriers to vaccination were the lack of doctor recommendation (57.4%) and concerns over the safety or efficacy of the vaccine (12.7%).

Randomized Controlled Trial
Older Age as a Predictive Risk Factor for Acute Mountain Sickness.
Older populations are increasing and comprise a substantial portion of high-altitude travelers. Aging physiology may influence susceptibility to acute mountain sickness, though prior research remains inconclusive. The goal of this study was to investigate the relationship between increasing age and acute mountain sickness. ⋯ Older age was not associated with incidence nor severity of acute mountain sickness. A history of altitude illness increased odds of acute mountain sickness and should be used for pre-ascent risk stratification.

Comparative Study
Differences in Inflammation, Treatment and Outcomes between Black and non-Black Patients Hospitalized for COVID-19: A Prospective Cohort Study.
Racial disparities in coronavirus disease 2019 (COVID-19) outcomes have been described. We sought to determine whether differences in inflammatory markers, use of COVID-19 therapies, enrollment in clinical trials, and in-hospital outcomes contribute to racial disparities between Black and non-Black patients hospitalized for COVID-19. ⋯ Racial differences in outcomes of patients with COVID-19 may be related to differences in inflammatory response and differential use of therapies.

The use of inhaled corticosteroids (ICS) in combination with inhaled bronchodilators for patients with chronic obstructive pulmonary disease (COPD) is a common practice in primary care settings. However, ICS-containing therapies may be less effective in patients with COPD compared with asthma, and in individuals with COPD who continue to smoke cigarettes. Preclinical studies suggest that inflammation in COPD is very different from in asthma. ⋯ ICS-containing therapies in patients with asthma who continue to smoke may also be less effective compared with patients who do not smoke. ICS-containing therapies may be inappropriately used in some patients with COPD, and their long-term use is associated with an increased risk for side effects, including pneumonia and bone fractures in some patients. Treatment for patients with COPD should be carefully evaluated, and anti-inflammatory/bronchodilatory strategies should be chosen based on individual patient characteristics and recommendations in current guidelines.
