This study aimed to determine hospital fear points, specific aspects of the hospital experience that are particularly frightening for children, and fear levels of children 5-10 years old who are admitted to the hospital. This descriptive cross-sectional study of 210 children in eastern Turkey aged 5-10 years used a Demographic Findings and Hospital Fears Form and the Child Fear Scale to collect data about the children's demographics, the opinions of the mothers about their children's fears, and the children's fears about the hospital. Children in the outpatient treatment services and emergency department were afraid of blood drawing, intravenous insertion, injections (shots), and separation from their mothers.

In patients whose chronic urticaria (CU) cannot be controlled with omalizumab 300 mg and antihistamines, the dose can be increased up to 600 mg. The study aimed to compare the clinical characteristics of patients receiving 300 mg versus higher doses of omalizumab, and to evaluate baseline predictors for updosing. A total of 159 patients who have been followed up at a tertiary care allergy center and received omalizumab for at least 12 months were included.

This study was aimed to identify the most frequently observed pathogens in uncomplicated urinary tract infections from outpatient urinary isolates obtained across seven different geographical regions in Türkiye and to determine whether the antibiotic resistance rates of these pathogens differ significantly between these regions. The study included patients aged 18 to 65 years who were diagnosed with uncomplicated urinary tract infections and had positive urine cultures from March 2021 to August 2022, across 37 different centers in Türkiye. The participating centers were selected based on their use of the disk diffusion method, in line with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines, to ensure standardization of urine culture data.

Introduction: End-stage kidney disease patients face a critical decision regarding kidney replacement therapy options, which include kidney transplantation, hemodialysis, or peritoneal dialysis (PD). This study aims to evaluate the impact of nurse-led education (NE) alone vs. NE combined with peer support on the patients' decision over PD treatment in chronic kidney disease patients.

Background: This study aimed to evaluate attitudes toward and exposure to gender discrimination in work life by chest diseases specialists and thoracic surgeons.

Methods: A total of 275 members of Turkish Thoracic Society (TTS) were included on a voluntary basis in this online cross-sectional questionnaire-survey using an internal member-only social media platform of TTS. The questionnaire form elicited items on sociodemographic characteristics, occupational characteristics and gender discrimination in work life (general opinions, attitudes and exposure).

There is limited data on the use of baseline IgE level as a predictor of omalizumab response in chronic urticaria (CU). The aim of the present study was to determine if baseline serum total IgE level is associated with response at six months of standard-dose omalizumab. The study was designed as a retrospective, single-center, cohort survey.

This study investigates the synthesis and characterization of Schiff base network-1 (SNW-1) covalent organic framework (COF) nanomaterials and their application in the fabrication of thin-film nanocomposite (TFN) membranes. The embedding of SNW-1 COF in reverse osmosis (RO) membranes with a polysulfone (PSf) substrate was done using the interfacial polymerization method. The result of the study demonstrated that the porous and hydrophilic structure of the COF increased the hydrophilic properties of the produced RO membranes.

Background: Patient no-show behavior is a critical factor complicating hospital resource optimization and causing waste. The inefficiency caused by patients' no-shows and the resulting increased operating costs negatively affect the hospitals' financial structure and service quality. For this reason, health managers must make accurate predictions about whether patients will attend an appointment and plan the appointment system within the framework of these predictions.

Molecularly-modified electrode materials that maintain stability over a broad pH range are rare. Typically, each electrochemical transformation necessitates a specifically tuned system to achieve strong binding and high activity of the catalyst. Here, we report the functionalisation of mesoporous indium tin oxide (mITO) electrodes with the macrocyclic host molecule pillar[6]arene (PA[6]).

<b>Introduction:</b> Colorectal cancer (CRC) prognosis is typically determined based on clinical stage and histopathological findings, yet patients with the same stage and histological structure can exhibit varying survival outcomes. This highlights the need for additional prognostic biomarkers. Serum biomarkers are gaining increasing significance due to their affordability and accessibility.

Article Synopsis
  • This study investigated gene expression related to stone formation in patients with recurrent calcium oxalate stones compared to individuals without a history of renal stones.
  • Nineteen patients with recurrent stones and 21 control patients were analyzed, with normal biochemical parameters and no significant urinary abnormalities noted.
  • Results showed that the gene expression related to stone formation was significantly higher in the stone-forming group, suggesting that this overexpression may contribute to the development of recurrent calcium oxalate stones.

Purpose: Cancer poses a significant global health challenge, demanding precise genomic testing for individualized treatment strategies. Targeted-panel sequencing (TPS) has improved personalized oncology but often lacks comprehensive coverage of crucial cancer alterations. Whole-genome sequencing (WGS) addresses this gap, offering extensive genomic testing.

Article Synopsis
  • Purpura fulminans (PF) is a serious condition that leads to blood clotting issues, causing serious skin and tissue damage.
  • A 4-year-old girl developed PF after a chickenpox infection, resulting in severe skin lesions and requiring amputation after multiple treatments over 26 weeks.
  • Vaccination against varicella-zoster virus (VZV) is crucial as it can prevent serious complications like PF, despite VZV usually causing mild illness.
