A Step Forward in Hypervirulent Klebsiella pneumoniae Diagnostics.

Hypervirulent Klebsiella pneumoniae (hvKp) can cause life-threatening infections in healthy community members. HvKp infections often involve multiple sites, some of which are unusual for classical K. pneumoniae (cKp) infections, such as the central nervous system, eyes, and fascia.

Genomic analysis of early ST32 Acinetobacter baumannii strains recovered in US military treatment facilities reveals distinct lineages and links to the origins of the Tn6168 ampC transposon.

Objectives: To study the population structure and genomic characteristics, including antimicrobial resistance genes, plasmid types and surface polysaccharide type, of the globally distributed Acinetobacter baumannii belonging to ST32 (Institut Pasteur scheme).

Methods: Antibiotic resistance phenotype for 19 antibiotics was determined using Vitek 2. Whole-genome sequencing was performed using the Illumina MiSeq platform.

Trends in Sickle Cell Disease Mortality: 1979-2020.

Background And Objectives: Although sickle cell disease (SCD)-related childhood mortality in the United States significantly improved in the 1990s, unclear is the trend in SCD-related mortality more recently given the continued disparities faced by this minoritized population. In this analysis, we aimed to (1) compare the overall and age-specific mortality rates from 1999 to 2009 vs 2010 to 2020 with a particular focus on the age of transition and (2) determine the most common causes of death for the US SCD population for 2010 to 2020.

Methods: We analyzed publicly available data from the Centers for Disease Control and Prevention WONDER database, a compilation of national-level mortality statistics from 1979 to 2020 derived from death certificates compiled by the National Center for Health Statistics.

Molecular Surveillance of Multidrug-Resistant Bacteria among Refugees from Afghanistan in 2 US Military Hospitals during Operation Allies Refuge, 2021.

In 2021, two US military hospitals, Landstuhl Regional Medical Center in Landstuhl, Germany, and Walter Reed National Military Medical Center (WRNMMC) in Bethesda, Maryland, USA, observed a high prevalence of multidrug-resistant bacteria among refugees evacuated from Afghanistan during Operation Allies Refuge. Multidrug-resistant isolates collected from 80 patients carried an array of antimicrobial resistance genes, including carbapenemases (bla, bla, and bla) and 16S methyltransferases (rmtC and rmtF). Considering the rising transmission of antimicrobial resistance and unprecedented population displacement globally, these data are a reminder of the need for robust infection control measures and surveillance.

Sickle cell disease in India: Not just a mild condition.

Sickle cell disease (SCD) is a common and life-threatening global health problem, with more than 500 000 affected infants born annually. The burden of SCD in sub-Saharan Africa is well established, but the comparably high prevalence in India is not well recognized and many consider SCD in India to be less severe. In their paper, a national study in India demonstrated the significant impact of SCD for patients, families and the healthcare system, supporting a call to action to recognize and address SCD as a serious and common health condition in India.
