High-mobility group box 1 protein, histone H3 and histone H4 are not associated with peripheral hypoperfusion in sepsis: a retrospective cohort study

Bruna Cassia Dal Vesco, Ana Carolina de Miranda, Fernanda do Carmo De Stefani et al. · 2026 · Einstein (São Paulo)

ABSTRACT Objective: The causal mechanisms of peripheral hypoperfusion in sepsis have not yet been fully elucidated. Therefore, this study aimed to investigate whether peripheral hypoperfusion in septic patients is associated with serum levels of damage-associated molecular patterns. Methods: A retrospective cohort study was conducted to compare serum levels of damage-associated molecular patterns - histone H3, histone H4, and high-mobility group box-1 protein (HMGB1) - with markers of tissue hypoperfusion - the peripheral perfusion index and the capillary refill time, using a single measuremen

‘Saga Stories in health talks’ for health promotion in Swedish child healthcare: results from a cluster-randomised hybrid type 1 effectiveness-implementation study

Maria Henström, Christine Delisle Nyström, Susanne Andermo et al. · 2025 · BMC Public Health

Abstract Background Early-life interventions are essential for improving public health since lifestyle behaviours are established already in childhood. Child healthcare (CHC) plays a crucial role in this context. The ‘Saga Stories in health talk’ (SSiHT) material includes a flipchart with colourful illustrations to facilitate CHC nurses’ routine health talks with parents and their children, and a hand-out material kit to support healthy lifestyle behaviours in the families. Our aim was to evaluate the effectiveness of the SSiHT intervention at the 5-year routine visit at CHC on parental self-e

Evaluation of the non-invasive indicators in predicting detrusor underactivity in individuals with small-volume prostatic hyperplasia and lower urinary tract symptoms

Yanyuan Wu, Yedie He, Jun Qi et al. · 2024 · Journal of Men's Health

This study was aimed to retrospectively analyze the potential of non-invasive serum biomarkers in clinically predicting the detrusor underactivity (DU) in benign prostatic hyperplasia (BPH) patients with lower urinary tract symptoms (LUTS) and low prostate volume (PV). The study enrolled 196 patients with BPH and LUTS at our hospital in the period from January 2018 to October 2023.

Optimising after-hours workflow of computed tomography orders in the emergency department

Joseph Choi, Rajesh Bhayana, Chenhan D Wang et al. · 2020 · BMJ Open Quality

Ordering and protocolling CT scans after-hours from the emergency department (ED) at our institution previously required discussion between the ED physician and radiology resident, which led to workflow inefficiency. Our intervention consisted of creating an electronic list of CT requests that radiology residents would monitor. Radiology protocolled straightforward requests and contacted the ordering physician for more details when required. We aimed to improve workflow efficiency, increase provider satisfaction and reduce CT turnaround time without significantly affecting CT utilisation. Plan

The Impact of the D727e Polymorphism has no Significant Role in Multi Nodular Goiter

Tug E., Sengül N., Aydin H. et al. · 2012 · Balkan Journal of Medical Genetics

Interactions between individual genetic and environ- mental factors determine the onset of the multi nodular goiter (MNG). The thyroid-stimulating hormone receptor (TSHR) gene is a convincing candidate gene in the pathogenesis of certain thyroid diseases including MNG. We investigated the codon 727 polymorphism (p.Asp727Glu, p.D727E) of the human TSHR gene using the polymerase chain reaction-restriction fragment length polymorphim (PCR-RFLP) methods in 31 Turkish patients with MNG and in 30 control subjects, aiming to evaluate the relationship between this polymorphism and MNG.

A study was carried out in the Kartuzy lake complex, which has been a receiver of raw domestic sewage since the 1950s. In 2018, the city’s sewage system of Kartuzy was modernized. An analysis of the water quality prior to the modernization of the sewage system revealed that the total phosphorus (TP) load that was introduced to the individual lakes from external sources substantially exceeded the dangerous load concentration (defined by Vollenweider) that causes accelerated eutrophication. The annual TP load introduced to the analyzed lakes in 2017 exceeded the critical load by 200% (Mielenko)
