Transcriptomic signatures of chronic active antibody-mediated rejection deciphered by RNA sequencing of human kidney allografts.

Natural killer (NK) cells mediate spontaneous cell-mediated cytotoxicity and antibody-dependent cell-mediated cytotoxicity. This dual functionality could enable their participation in chronic active antibody-mediated rejection (CA-ABMR). Earlier microarray profiling studies have not subcategorized antibody-mediated rejection into CA-ABMR and active-ABMR, and the gene expression pattern of CA-ABMR has not been compared with that of T cell-mediated rejection (TCMR).

Endocrine Toxicity and Outcomes in Patients With Metastatic Malignancies Treated With Immune Checkpoint Inhibitors.

Context: Immune checkpoint inhibitors (ICIs) have gained a revolutionary role in management of many advanced malignancies. However, immune-related endocrine events (irEEs), have been associated with their use. irEEs have nonspecific clinical presentations and variable timelines, making their early diagnosis challenging.

Coronavirus Disease 2019 (COVID-19) Complicated by Acute Respiratory Distress Syndrome: An Internist's Perspective.

A pandemic outbreak of a novel coronavirus disease (COVID-19) that began in Wuhan, China, in December 2019 has spread rapidly to multiple countries. In the United States, the first confirmed case was reported on January 20, 2020, and since then, the number of cases is rising exponentially on a daily basis. We report a case of COVID-19 infection that presented with symptoms suggestive of pneumonia.

Acute Reactive Acalculous Cholecystitis Secondary to Duodenal Ulcer Perforation.

Acute cholecystitis is the inflammation of the gallbladder, classically caused by gall stones obstructing the cystic duct. In contrast, acalculous cholecystitis is a gallbladder inflammation occurring in the absence of cholelithiasis with a reported prevalence of 10% of all cases of acute cholecystitis. Reactive acalculous cholecystitis is an extremely rare subset of this disease that results from an adjacent inflammatory or infectious intra-abdominal process that may lead to gallbladder stasis, ischemia, and subsequent wall inflammation.
