Association of the Systemic Inflammation Response Index with Functional Outcome in Acute Large Vessel Occlusion Stroke Patients Receiving Mechanical Thrombectomy.

Purpose: The systemic inflammation response index (SIRI) has recently emerged as a novel inflammatory and prognostic marker across various diseases. However, there is limited research examining the relationship between SIRI and 90-day functional outcome in patients with acute large vessel occlusion stroke (ALVOS) undergoing mechanical thrombectomy (MT). This study aimed to investigate the potential of SIRI as an innovative, inflammation-based predictor of 90-day functional outcome.

Liver abscess and splenic infarction due to Yersinia pseudotuberculosis bloodstream infection: a case report.

Background: Yersinia pseudotuberculosis is an emerging zoonotic intestinal pathogen primarily transmitted through contaminated food and water. Infections caused by Yersinia pseudotuberculosis are typically self-limiting, often presenting as gastroenteritis or "pseudoappendicitis," which is characterized by fever and abdominal pain. Although bloodstream infections with Yersinia pseudotuberculosis are rare, they can lead to multiple distant sites of infection, including abscesses in the liver, spleen, and kidneys, as well as in the hip and knee joints, particularly in individuals with underlying immunodeficiency.

Effect of acupuncture on quality of life in atrial fibrillation: study protocol for a randomised controlled trial.

Introduction: Atrial fibrillation (AF) is the prevalent cardiac arrhythmia and can significantly impair the quality of life (QoL). Although catheter ablation (CA) is an established treatment for AF,post-procedural complications or perceived inadequate control of AF may diminish the QoL for some patients, potentially even to levels lower than pre-procedure. Preliminary findings from our previous pilot trial indicate that acupuncture may positively influence QoL in AF patients post-CA.

Considering that changes in the CAR are associated with AKI incidence in AP cases, this work aims to explore whether CAR can be used as the innovative, inflammation-based diagnostic marker for AKI in AP patients.

Methods: The current retrospective cohort study consecutively enrolled AP patients admitted to First College of Clinical Medical Science of China Three Gorges University during the period from January 2019 to October 2023.

To nap or not? Evidence from a meta-analysis of cohort studies of habitual daytime napping and health outcomes.

Habitual daytime napping is a common behavioral and lifestyle practice in particular countries and is often considered part of a normal daily routine. However, recent evidence suggests that the health effects of habitual daytime napping are controversial. We systematically searched PubMed, Web of Science, Embase, and Cochrane Library databases from inception to March 9, 2024, to synthesize cohort studies of napping and health outcome risk.

Social defeat stress induces liver injury by modulating endoplasmic reticulum stress in C57BL/6J mice.

Social defeat stress is associated with endoplasmic reticulum (ER) stress, inflammation and apoptosis. ER stress is thought to contribute to many lifestyle diseases such as liver injury, cardiovascular dysfunction and depression. We investigated the expression of the ER stress markers RNA-dependent protein kinase-like ER kinase (PERK), eukaryotic translation initiation factor 2α (eIF2α) and C/EBP homologous protein (CHOP), as well as inflammatory and apoptotic factors, to assess how social defeat stress induces liver injury.

OXTR polymorphisms associated with severity and treatment responses of schizophrenia.

The mechanisms generating specific symptoms of schizophrenia remain unclear and genetic research makes it possible to explore these issues at a fundamental level. Taking into account the associations between the oxytocin system and social functions, which are apparently impaired in schizophrenia patients, we hypothesized that the oxytocin receptor gene (OXTR) might be associated with schizophrenia symptoms in both severity and responses to antipsychotics and did this exploratory positional study. A total of 2363 patients with schizophrenia (1181 males and 1182 females) included in our study were randomly allocated to seven antipsychotic treatment groups and received antipsychotic monotherapy for 6 weeks.

Conversion of THz refractive index variation to detectable voltage change realized by a graphene-based Brewster angle device.

The Brewster effect has been previously reported as an essential mechanism for terahertz (THz) wave sensing application. However, generally in a sensing application, a complex rotation apparatus is required for detecting the slight change in Brewster angle. Here, we propose a graphene-based Brewster angle device operating at a specific terahertz frequency capable of sensing the refractive index at a fixed incident angle.

Chemometrics applied quantitative analysis of iron oxide mixtures by terahertz spectroscopy.
