Prevalence, misclassification, and clinical consequences of the heteroresistant phenotype in Escherichia coli bloodstream infections in patients in Uppsala, Sweden: a retrospective cohort study.

Background: Antibiotic heteroresistance is a common bacterial phenotype characterised by the presence of small resistant subpopulations within a susceptible population. During antibiotic exposure, these resistant subpopulations can be enriched and potentially lead to treatment failure. In this study, we examined the prevalence, misclassification, and clinical effect of heteroresistance in Escherichia coli bloodstream infections for the clinically important antibiotics cefotaxime, gentamicin, and piperacillin-tazobactam.

Cardiometabolic risk factors in the Swedish Werlabs cohort based on self-initiated health screening: cohort profile.

Purpose: There is limited research on individuals undergoing self-initiated health examinations, and the Werlabs cohort will be a base for such research.

Participants: All individuals aged 18 or older who had undertaken a self-initiated health examination at Werlabs AB with at least one recorded value of creatinine or cholesterol in Sweden (from 1 January 2015 through 31 December 2023) was included. Medical history and anthropometric measurements were self-reported through an online questionnaire.

Integration of personalised ultrasensitive ctDNA monitoring of patients with metastatic breast cancer to reduce imaging requirements.

Circulating tumour DNA (ctDNA) is an emerging biomarker for monitoring cancers. The personalised disease monitoring in metastatic breast cancer (PDM-MBC) study is an ongoing study instigated to evaluate ctDNA as a biomarker to individualise imaging requirements in patients with MBC. Patients receiving first-line endocrine therapy (aromatase inhibitor + cyclin-dependent kinase 4/6 inhibitor) had plasma samples collected pre-treatment, weeks 2 and 4, and concurrently with imaging until progressive disease (PD).

Protective Effects of the Food Supplement Flexovital in a Model of Cardiovascular-Kidney-Metabolic Syndrome in Mice.

The prevalence of cardiovascular-kidney-metabolic (CKM) syndrome is increasing rapidly, and cardiovascular complications pose significant risks in individuals with kidney disease and metabolic dysfunction. Understanding the mechanisms of CKM disorders is crucial, as is the discovery of novel preventive treatments. This study aimed to examine the therapeutic effects of a specially formulated nitric oxide-enhancing food additive in a mouse model of CKM syndrome induced by unilateral nephrectomy (UNX) in combination with chronic Western diet (WD) feeding.

Decreased Adipose Lipid Turnover Associates With Cardiometabolic Risk and the Metabolic Syndrome.

Background: Disturbed white adipose tissue function is important for cardiometabolic risk and metabolic syndrome (MetS). Whether this involves adipose lipid turnover (lipolysis and synthesis of triglycerides) is unknown and was presently investigated in subcutaneous adipose tissue, the body's largest fat depot.

Methods: In cross-sectional studies in 78 subjects, adipose lipid age, representing overall lipid turnover (mobilization and storage), and lipid storage capacity were assessed by the incorporation of atmospheric C into adipose lipids.
