Background: Asthma is one of the most common causes of chronic respiratory disease, and countries with low socioeconomic status have both a high prevalence of asthma and asthma-related death.

Objective: In this study, we aimed to determine socioeconomic levels of asthmatic patients according to a national database and investigate the effects of social markers on disease control in our region.

Methods: This is an analysis of data from 2053 adult asthma patients from a multicentre chart study in Turkey.

Montelukast, a leukotriene receptor antagonist (LTRA) approved for the treatment of asthma and allergic rhinitis, is widely used, though real-world data on its application in asthma management remain limited. This registry-based study evaluated the use of montelukast in adult asthma patients, examining demographic and disease characteristics, asthma control status, asthma phenotypes, presence of atopy, and treatment regimens. Among 2053 patients analyzed, 61.

Significance: Assessment of pain and its clinical diagnosis rely on subjective methods which become even more complicated under analgesic drug administrations.

Aim: We aim to propose a deep learning (DL)-based transfer learning (TL) methodology for objective classification of functional near-infrared spectroscopy (fNIRS)-derived cortical oxygenated hemoglobin responses to painful and non-painful stimuli presented under different timings post-analgesic and placebo drug administration.

Approach: A publicly available fNIRS dataset obtained during painful/non-painful stimuli was used.

Current guidelines recommend adding long-acting muscarinic antagonists (LAMAs) in patients with uncontrolled asthma, despite the use of moderate to high doses of inhaled steroid-long-acting beta agonists (ICS/LABA). This study aims to analyze the factors related to the prescription of add-on LAMA in clinical practice for asthma patients, shedding light on physicians' preferences. This study included adult asthma patients on add-on LAMA and ICS/LABA monitored for at least one year in a national registry comprising 2053 asthmatics.

Non-alcoholic fatty liver disease (NAFLD) is a growing global health concern closely linked to metabolic disorders, including obesity, insulin resistance, and dyslipidemia. Emerging evidence suggests that the gut-liver axis plays a critical role in the pathogenesis of NAFLD, with recent research highlighting the influence of gut microbiota, including fungal species such as Saccharomyces boulardii (). This study aimed to evaluate the effects of on lipid metabolism and oxidative stress in a rat model of fructose-induced NAFLD.

Prosthetic valve thrombosis (PVT) is a critical and life-threatening condition driven by multifactorial etiologies, including genetic predispositions. The study was designed as a single-center retrospective manner. Echocardiographic features and genetic test including factor II/prothrombin (G20210A), factor V Leiden (G1691A), factor V R2 (A4070G), apolipoprotein (Apo) B-100 (G10708A), ApoE (C112R), ApoE (R158C), methylenetetrahydrofolate reductase (MTHFR) C677T, MTHFR A1298C, factor XIII G103T (V34L), β-fibrinogen (455G>A), PAI-1 4G/5G, and HPA-1 GPIIIa (T196C) genotyping variations were assessed.

Article Synopsis
  • * It found that the RSV only group had lower pH and higher rates of bronchiolitis, while the RSV with viral agents group experienced longer hospital stays and more severe symptoms.
  • * Additionally, cases with bacterial co-infections were generally younger and had different clinical markers, highlighting that combined viral and bacterial infections can worsen RSV severity and impact treatment approaches like High Flow Nasal Cannula-Oxygen Therapy.

  • Chronic Limb-Threatening Ischemia (CLTI) is a severe form of peripheral artery disease linked to significant health risks, including high limb amputation rates and reduced quality of life.
  • The study examined the relationship between the Prognostic Nutritional Index (PNI), which indicates immunological and nutritional health, and mortality in CLTI patients following endovascular therapy.
  • Results highlighted that lower PNI levels were associated with higher mortality, especially in older patients with chronic conditions, suggesting PNI could be a valuable predictor of survival outcomes in CLTI cases.

Objectives: Cardiac diastolic dysfunction (left ventricular diastolic dysfunction [LVDD]) is a well-known predictor of heart failure. We hypothesized that sarcopenia is independently associated with diastolic dysfunction. We aimed to investigate the association of the most recent consensus definition of sarcopenia with LVDD.

Differences in corticocerebral structure and function between males and females and their effects on behavior and the prevalence of various neuropsychiatric disorders have been considered as a fundamental topic in various fields of neuroscience. Recent studies on working memory (WM) reported the impact of sex on brain connectivity patterns, which reflect the important role of functional connectivity in the sex topic. Working memory, one of the most important cognitive tasks performed by regions of the PFC, can provide evidence regarding the presence of a difference between males and females.

Introduction: Migraine and epilepsy are two episodic disorders that share common pathophysiological mechanisms. The aim of our research was to assess the possible shared etiopathogenesis by analyzing the relations of headache, and seizure triggers, based on information obtained from a national cohort surveying the headache characteristics of 809 patients who had been diagnosed with idiopathic/genetic epilepsy.

Material And Methods: Our study utilized data from a multi-center, nationwide investigation of headaches in 809 patients with idiopathic/genetic epilepsy.

Article Synopsis
  • The study assessed the impact of Rhinapi nasal spray on allergic rhinitis symptoms among 10,000 participants in Turkey over a 3-week period.
  • The treatment led to significant improvements in total symptom scores, quality of life (QoL) scores, and otolaryngological examination scores, with statistically significant changes before and after usage.
  • The findings suggest that Rhinapi effectively reduces symptoms of allergic rhinitis and can be considered as an additional treatment option for those affected.

Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes.

The aim of this research was to determine the anti-inflammatory effect of betaine on sepsis-induced acute respiratory distress syndrome (ARDS) in rats through histopathological examination, radiologic imaging, and biochemical analysis. Eight rats were included in the control group, and no procedure was performed. Feces intraperitoneal procedure (FIP) was performed on 24 rats to create a sepsis-induced ARDS model.

Article Synopsis
  • The study explores the debate between performing orchiectomy or orchidopexy after testicular torsion, focusing on the need for objective criteria to define testicular viability.
  • Researchers analyzed 289 cases across 14 centers, finding that 8.8% of testes showed reversible grade 1 injuries despite adverse clinical findings like prolonged symptoms.
  • The results suggest the potential for testicular fixation, as many patients with severe symptoms did not have conclusive high-grade injuries, indicating a need for improved criteria in evaluating testicular health post-torsion.*

Precision/personalized medicine in oncology has two key pillars: molecular profiling of the tumors and personalized reporting of the results in ways that are clinically contextualized and triangulated. Moreover, neurosurgery as a field stands to benefit from precision/personalized medicine and new tools for reporting of the molecular findings. In this context, glioblastoma (GBM) is a highly aggressive brain tumor with limited treatment options and poor prognosis.
