Co-existence of two bla and bla on distinct plasmids in a carbapenem-resistant Klebsiella pneumoniae from a tertiary hospital, Tanzania.

Purpose: To understand the mechanisms of carbapenem-resistant Klebsiella pneumoniae (CRKP) from Tanzania and characterize the genomes carrying the carbapenemase genes.

Methods: Clinical CRKP isolates were selected from ongoing antimicrobial-resistant surveillance at Muhimbili National Hospital, Dar es Salaam, Tanzania. Whole-genome sequencing was performed utilizing Illumina and Nanopore platforms.

Similarities in B Cell Defects between Aging and Obesity.

The aging population is increasing worldwide, and there is also an increase in the aging population living with overweight and obesity, due to changes in lifestyle and in dietary patterns that elderly individuals experience later in life. Both aging and obesity are conditions of accelerated metabolic dysfunction and dysregulated immune responses. In this review, we summarize published findings showing that obesity induces changes in humoral immunity similar to those induced by aging and that the age-associated B cell defects are mainly due to metabolic changes.

Distress tolerance and perceived cancer-related cognitive impairment in nonmetastatic breast cancer.

Objective: Cancer- and cancer treatment-related cognitive impairment (CRCI) is reported by many women with breast cancer (BC). Distress tolerance (DT) refers to both the perceived capacity and behavioral act of withstanding uncomfortable/aversive/negative emotional and/or physical experiences. Poor DT has been associated with worse cognitive performance, including executive dysfunction.

Improving Ebola virus disease outbreak control through targeted post-exposure prophylaxis.

Ebola virus disease kills more than half of people infected. Since the disease is transmitted via close human contact, identifying individuals at the highest risk of developing the disease is possible on the basis of the type of contact (correlated with viral exposure). Different candidates for post-exposure prophylaxis (PEP; ie, vaccines, antivirals, and monoclonal antibodies) each have their specific benefits and limitations, which we discuss in this Viewpoint.
