From human to superhuman: the impact of the microbiome on physiology.

The complex microbial community residing in the human gut has long been understood to regulate gastrointestinal physiology and to participate in digestive diseases, but its extraintestinal actions and influences are increasingly recognized. This article discusses bidirectional interactions between the gut microbiome and athletic performance, metabolism, longevity and the ability of the gut-brain axis to influence cognitive function and mental health.

CpG island methylator phenotype classification improves risk assessment in pediatric T-cell Acute Lymphoblastic Leukemia.

Current intensive treatment of pediatric T-cell acute lymphoblastic leukemia (T-ALL) has substantial side-effects, highlighting a need for novel biomarkers to improve risk stratification. Canonical biomarkers such as genetics and immunophenotype are largely not used in pediatric T-ALL stratification. This study aimed to validate the prognostic relevance of DNA methylation CpG island methylator phenotype (CIMP) risk stratification in two pediatric T-ALL patient cohorts: the Nordic NOPHO ALL2008 T-ALL study cohort (n=192) and the Dutch DCOG ALL-10/ALL-11 validation cohorts (n=156).

A Non-Centrifugation Method to Concentrate and Purify Extracellular Vesicles Using Superabsorbent Polymer Followed by Size Exclusion Chromatography.

Extracellular vesicles (EVs) can be isolated and purified from cell cultures and biofluids using different methodologies. Here, we explored a novel EV isolation approach by combining superabsorbent polymers (SAP) in a dialysis membrane with size exclusion chromatography (SEC) to achieve high concentration and purity of EVs without the use of ultracentrifugation (UC). Suspension HEK293 cells transfected with CD63 coupled with Thermo Luciferase were used to quantify the EV yield and purity.

Introduction: Physical therapy encompasses a broad range of treatment options, often utilized in clinical settings where pharmaceutical interventions are standard. The potential for physical therapy to contribute to sustainable healthcare by reducing environmental impact, while maintaining the quality of care, remains underexplored. This study aimed to map existing research comparing physical therapy to pharmaceuticals, with a specific focus on whether these studies address aspects of sustainable development.

Short-term variability of Alzheimer's disease plasma biomarkers in a mixed memory clinic cohort.

Background: For clinical implementation of Alzheimer's disease (AD) blood-based biomarkers (BBMs), knowledge of short-term variability, is crucial to ensure safe and correct biomarker interpretation, i.e., to capture changes or treatment effects that lie beyond that of expected short-term variability and considered clinically relevant.

NLRP3 is a BMI-independent mediator of stable COPD.

Purpose: The inflammatory response in animal models of chronic obstructive pulmonary disease (COPD) is activated by the NLR-family-pyrin-domain-containing-3 (NLRP3) inflammasome pathway, which is also known to play a role in obesity-related inflammation. The NLRP3/caspase-1/interleukin (IL)-1β pathway might be involved in the progression of COPD with increasing body mass index. To our knowledge, no previous studies have explored the role of NLRP3 inflammasome markers in linking COPD and obesity.

Fluoroquinolone-specific resistance trajectories in E. coli and their dependence on the SOS-response.

Background: Fluoroquinolones are indispensable antibiotics used in treating bacterial infections in both human and veterinary medicine. However, resistance to these drugs presents a growing challenge. The SOS response, a DNA repair pathway activated by DNA damage, is known to influence resistance development, yet its role in fluoroquinolone resistance is not fully understood.

Sociodemographic characteristics and health status of women with breast cancer and COVID 19 diagnosis by menopausal status a cross sectional study.

The goal of this work is to investigate the sociodemographic characteristics and health status of women with breast cancer (BC) in association with COVID-19 by menopausal status. In a Swedish register-based cross-sectional study, we compared women with BC and with or without a positive COVID-19 test, stratified by menopausal status (age ≥ 51 years). Socioeconomic characteristics and health status (represented by diagnoses registered in 5 years- and prescription dispensed in 2 years preceding Jan 2020) were considered in association with COVID-19 diagnosis.

Aim: To investigate fasting metabolism in children with very long-chain acyl-CoA dehydrogenase deficiency (VLCADD) and medium-chain acyl-CoA dehydrogenase deficiency (MCADD) using microdialysis technique.

Methods: Twelve patients (7 with VLCADD, 5 with MCADD, mean age 4.9 years, 10/12 diagnosed via newborn screening) were recruited for investigation in connection to clinical fasting examinations at the Karolinska University Hospital (between 2015 and 2024).

Reconsidering the Relationship Between Criminal Insanity and Delusions.

This article discusses the relevance of delusions for a finding of criminal insanity. The authors start from the recognition that the psychiatric notion of delusion is considered relevant to criminal insanity in most jurisdictions and therefore integrates psychiatric perspectives to define delusions. The key focus is on the differences regarding how and why delusions matter legally between the Anglo-American and the Norwegian approach to criminal insanity.

Platelet aggregation and thromboelastometry monitoring in women with preeclampsia: a prospective observational study.

Background: Thrombocytopenia affects 12-20% of women with preeclampsia and a low platelet count impairs coagulation. Women with preeclampsia have an increased risk of both cerebral hemorrhage, thromboembolism, and postpartum hemorrhage. Studies of platelet function and coagulation in women with preeclampsia show conflicting results.

Aortic regurgitation in ankylosing spondylitis-an echocardiography follow-up study.

Objectives: To investigate the long-term course of aortic regurgitation (AR) and the width of the proximal ascending aorta (PAA) in patients with ankylosing spondylitis (AS).

Method: This is a follow-up cohort study of patients with AS examined with echocardiography at inclusion (2009 to 2011). Out of the initial 187, a subgroup of 52 patients (54% men, mean age 62 years) was selected for follow-up based on presence/absence of AR at baseline; 26 with AR (18 mild, 7 moderate, 1 severe) and 26 age/sex-matched without AR.

The objectives of this study were to investigate whether an intervention with a person-centered approach supported by e-Health technology can impact self-efficacy.

Rome Foundation Working Team Report: Consensus Statement on the Design and Conduct of Behavioural Clinical Trials for Disorders of Gut-Brain Interaction.

Background: Brain-gut behaviour therapies (BGBT) have gained widespread acceptance as therapeutic modalities for the management of disorders of gut-brain interaction (DGBI). However, existing treatment evaluation methods in the medical field fail to capture the specific elements of scientific rigour unique to behavioural trial evaluation.

Aims: To offer the first consensus on the development and testing of BGBT in DGBI.

A probabilistic approach to estimating timber harvest location.

Determining the harvest location of timber is crucial to enforcing international regulations designed to protect natural resources and to tackle illegal logging and associated trade in forest products. Stable isotope ratio analysis (SIRA) can be used to verify claims of timber harvest location by matching levels of naturally occurring stable isotopes within wood tissue to location-specific ratios predicted from reference data ("isoscapes"). However, overly simple models for predicting isoscapes have so far limited the confidence in derived predictions of timber provenance.

Self-reported health, persistent symptoms, and daily activities 2 years after hospitalization for COVID-19.

Introduction: Since the onset of the COVID-19 pandemic, 775 million cases have been reported globally. While many individuals recover fully, a significant proportion develop persistent symptoms. Numerous studies have investigated the long-term symptoms of COVID-19; however, the full extent and impact of these symptoms remain inadequately understood.

Methods: We conducted semi-structured telephone interviews with 30 men (nine participants and 21 non-participants) from Stockholm County who received OPT invitations.

Feasibility and potential diagnostic value of [F]PI-2620 PET in patients with down syndrome and Alzheimer's disease: a case series.

Purpose Of The Report: Adults with Down Syndrome (DS) have a substantially increased risk for Alzheimer's disease (AD) due to the triplicated amyloid-precursor-protein gene on chromosome 21, resulting in amyloid and tau accumulation. However, tau PET assessments are not sufficiently implemented in DS-AD research or clinical work-up, and second-generation tau tracers such as [F]PI-2620 have not been thoroughly characterized in adults with DS. We aim at illustrating feasibility and potential diagnostic value of tau PET imaging with [F]PI-2620 for the diagnosis of DS-AD.

Single- versus two-test criteria for cognitive impairment: associations with CSF and imaging markers in former American football players.

 Cognitive impairment is a core feature of traumatic encephalopathy syndrome (TES), the putative clinical syndrome of chronic traumatic encephalopathy-a neuropathological disease associated with repetitive head impacts (RHI). Careful operationalization of cognitive impairment is essential to improving the diagnostic specificity and accuracy of TES criteria. We compared single- versus two-test criteria for cognitive impairment in their associations with CSF and imaging biomarkers in male former American football players.

Gut bacterium Intestinimonas butyriciproducens improves host metabolic health: evidence from cohort and animal intervention studies.

Background: The human gut microbiome strongly influences host metabolism by fermenting dietary components into metabolites that signal to the host. Our previous work has shown that Intestinimonas butyriciproducens is a prevalent commensal bacterium with the unique ability to convert dietary fructoselysine to butyrate, a well-known signaling molecule with proven health benefits. Dietary fructoselysine is an abundant Amadori product formed in foods during thermal treatment and is part of foods rich in dietary advanced glycation end products which have been associated with cardiometabolic disease.
