Two-component system GrpP/GrpQ promotes pathogenicity of uropathogenic Escherichia coli CFT073 by upregulating type 1 fimbria.

Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTIs). Invasion into bladder epithelial cells (BECs) on the bladder luminal surface via type 1 fimbria is the first critical step in UPEC infection. Although type 1 fimbria expression increases during UPEC invasion of BECs, the underlying regulatory mechanisms remain poorly understood.

Whether the fat-soluble vitamins A, D, E, and K are associated with development of graft-versus-host disease (GvHD) after allogeneic stem cell transplantation, is unclear. We assessed if the levels of these vitamins were associated with development of GvHD during the first year after transplantation using data from a two-armed randomized nutritional intervention trial. Changes in plasma levels during 1-year follow-up were analyzed using a linear mixed model for repeated measurements.

Viral infections of the central nervous system (CNS) have been emerging and re-emerging worldwide, and the Australasia region has not been spared. Enterovirus A71 and enterovirus D68, both human enteroviruses, are likely to replace the soon-to-be eradicated poliovirus to cause global outbreaks associated with neurological disease. Although prevalent elsewhere, the newly emergent orthoflavivirus, Japanese encephalitis virus (genotype IV), caused human infections in Australia in 2021, and almost certainly will continue to do so because of spillovers from the natural animal host-vector life cycle endemic in the country.

Article Synopsis
- The study focused on identifying situations that lead to metformin-associated lactic acidosis (MALA) in ICU patients and evaluating its preventability.
- A total of 198 MALA cases were assessed, with 19.2% resulting in death; the majority of patients had acute events like dehydration or severe infections that contributed to the condition.
- The findings indicated that MALA is often preventable, highlighting the need for better physician and patient education regarding metformin use during high-risk medical situations.

Mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase 2 (HMGCS2) deficiency is a rare, potentially life-threatening autosomal recessive disorder resulting from mutations in the HMGCS2 gene, leading to impaired ketogenesis. We systematically reviewed the clinical presentations, biochemical and genetic abnormalities in 93 reported cases and 2 new patients diagnosed based on biochemical findings. Reported onset ages ranged from 3 months to 6 years, mostly before the age of 3.
