New Onset Refractory Status Epilepticus (NORSE) is a rare and severe condition characterized by refractory seizures in individuals without a prior history of epilepsy. This case report describes a 37-year-old woman diagnosed with anti-glutamic acid decarboxylase 65 (anti-GAD65) antibody-positive encephalitis-related NORSE. Her seizures were refractory to multiple interventions, including anti-seizure medications, anesthetics, immunotherapies, a ketogenic diet, and electroconvulsive therapy.

Background: Therapeutic drug monitoring (TDM) and target concentration intervention (TCI) represent significant advancements in individualized medicine, aiming to tailor dosages based on patient-specific characteristics. These approaches account for intra- and inter-individual physiological and clinical variability, with the goal of improving target attainment and clinical remission while reducing treatment failure and adverse effects.

Objectives: The objective is to assess and enhance the current body of randomized controlled trials (RCTs) that have investigated alternative personalized dosing strategies, such as TDM and TCI, in terms of their efficacy and safety for individualized antimicrobial dosing in pediatric populations.

Determination of nuclear and/or cytoplasmic expression of β-catenin by immunohistochemistry in patients with endometrial cancer (EC) may constitute a potential diagnostic method for identifying patients with a catenin β1 (CTNNB1) gene mutation and those at risk of disease recurrence. The present study aimed to investigate β-catenin expression patterns in hysterectomy specimens of patients with endometrioid type EC using immunohistochemistry, and to examine the prognostic impact of β-catenin. The study was a single-institutional, retrospective cohort trial enrolling consecutive patients with a postoperative histopathological diagnosis of endometrioid EC who underwent hysterectomy between January 2015 and December 2018.

Background: Transfusion-dependent thalassemia (TDT) is an autosomal recessive disorder characterized by defective hemoglobin synthesis, leading to severe complications such as iron overload and multi-organ dysfunction. This study aims to elucidate the distinctive clinical and biochemical profiles of TDT patients compared to healthy controls, with an emphasis on cardiovascular risk assessment using novel markers such as the Plasma Atherogenic Index (PAI) and Triglyceride-Glucose (TyG) index.

Methods: This cross-sectional study included 32 TDT patients and 36 healthy controls, matched for age and gender.

Diabetic foot ulcers and infections are complications that can result in significant morbidity such as the need for amputations, especially in uncontrolled diabetes, thereby profoundly impacting quality of life. While traditional treatments like wound care and antibiotics are effective, there is growing interest in the role of micronutrients (such as vitamins C, D, E, zinc and magnesium) in improving outcomes. This study aims to evaluate how these micronutrients affect diabetic foot infections and the need for amputation, offering insights to enhance overall prognosis.

Introduction: Assessment of drug-related adverse events is essential to fully understand the benefit-risk balance of any drug exposure, weighing efficacy versus safety. This is needed for both drug labeling and clinical decision-making. Assessment is based on seriousness, severity and causality, be it more difficult to apply in neonates.

Background: For hospitalized adults, it is important to initiate the early reintroduction of oral food in accordance with nutrition support team guidelines. The aim of this study was to develop and validate a machine learning-based algorithm that predicts the early termination of medical nutritional therapy (the transition to oral feeding).

Methods: This retrospective cohort study included consecutive adult patients admitted to the Hacettepe hospital (from 1 January 2018 to 31 December 2022).

Adolescents with psychiatric disorders may struggle with medication adherence and this can lead to ineffective treatment. Subjective factors, such as attitudes, beliefs, experiences, have a greater impact on adherence in adolescents than objective factors. To better understand these subjective attitudes, self-evaluation rating scales should be developed.

Objective: We aimed to investigate differences between HPV-16 mono- and HPV-16/18 co-infections in terms of cervical dysplasia and invasive cancer.

Methods: This multicentre, retrospective study spanned from December 2017 to December 2020, involving women who visited gynaecological oncology clinics for colposcopy with either HPV-16 or HPV-16/18 positivity. A total of 736 patients, 670 in Group 1 (HPV-16 positivity) and 66 in Group 2 (HPV-16/18 positivity), were compared for the presence of CIN2+ lesions detected by colposcopic biopsy or endocervical curettage (ECC).

Background: Surgical site infections (SSI) are characterized by infections occurring in the surgical incision site, organ or cavity in the postoperative period. Adherence to surgical antimicrobial prophylaxis (SAP) is paramount in mitigating the occurrence of SSIs. In this study, we aimed to evaluate the appropriateness of SAP use in patients undergoing surgical procedures in the field of general surgery according to the American Society of Health-System Pharmacists (ASHP) guideline and to determine the difference between the pre-training period (pre-TP) and the post-training period (post-TP) organized according to this guideline.

This study aims to investigate the effect of the COVID-19 pandemic on accrual-based earnings management (EM) based upon a sampling of 938 listed firms from four selected European countries (United Kingdom, Italy, Spain, and Türkiye) during 2016-2020. We find that firms engage more in accrual-based EM through income-increasing and income-decreasing accruals in the year of the COVID-19 pandemic relative to the period before the pandemic. These findings imply that financial reporting reliability and usefulness decreased in the period of the pandemic.

Despite the theoretical benefits, the favorable effect of preoperative carbohydrate loading on postoperative morbidity remains controversial. Most of the outcomes reported in the literature are derived from non-gynecologic surgery data, with only one study involving a limited number of patients specifically in gynecological oncology. The present study aimed to investigate the impact of carbohydrate loading, as a single element of enhanced recovery after surgery protocols, on postoperative course and morbidity in patients undergoing debulking surgery for epithelial ovarian cancer (EOC).
