Sarcoidosis is a systemic inflammatory condition characterized by noncaseating granulomas. Lung involvement is typical, while extrapulmonary manifestations, notably lymphadenopathy, are observed in a significant proportion of cases. The etiology involves complex interactions among immune cells and mediators, resulting in granuloma formation capable of independently producing 1,25-dihydroxyvitamin D, leading to unregulated hypercalcemia and hypercalciuria.

Its pathogenesis is characterized by a self-perpetuating cycle of bradycardia that is potentiated by the concomitant occurrence of medication use, hyperkalemia, and renal failure. AV nodal blocking agents are commonly implicated in BRASH syndrome.

Throughout the COVID-19 pandemic various epidemiologic trends have been observed in other respiratory viruses including a reduction in influenza and respiratory syncytial virus infections following onset of the COVID-19 pandemic. Observations suggest that infections with other respiratory viruses were reduced with social distancing, mask wearing, eye protection, and hand hygiene practices.

Herein, we present a case series of three patients with pulmonary consolidations due to necrotizing pneumonia, pneumonia, and disseminated infection, who were diagnosed by microbial cell-free DNA next-generation sequencing. We observed that this new sequencing modality was in agreement with gold-standard diagnostics, posing a potential solution to the problem of limited capability in diagnosing infections in hematological malignancy patients.

In this retrospective study of 105 severe acute respiratory coronavirus virus 2 (SARS-CoV-2)-infected cancer patients with longitudinal nasopharyngeal sampling, the duration of viral shedding and time to attain cycle threshold >30 was longer in patients with hematologic malignancy than in those with solid tumors. These findings have important public health implications.

This study seeks to determine what contribution nursing home status makes to theses occurrences, independent of comorbid conditions.
Methods: Using the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database, the 30-day postoperative outcomes of the 5 commonest nonemergent inpatient procedures performed on nursing home residents were compared with those in nonnursing home residents using logistic regression analysis.
