Advances in artificial intelligence (AI) are reshaping mobility through autonomous vehicles (AVs), which may introduce risks such as technical malfunctions, cybersecurity threats, and ethical dilemmas in decision-making. Despite these complexities, the influence of consumers' risk preferences on AV acceptance remains poorly understood. This study explores how individuals' risk preferences affect their choices among private AVs (PAVs), shared AVs (SAVs), and private conventional vehicles (PCVs).

Introduction: Respiratory syncytial virus (RSV) vaccination could improve health equity by protecting individuals who are disproportionally at increased risk of RSV infection and severe RSV-related outcomes. However, limited information is available about RSV-related disparities among United States (US) adults.

Areas Covered: We reviewed US-specific literature regarding disparities across adult populations in having risk factors for severe RSV disease (cardiopulmonary disease, diabetes, liver disease, kidney disease).

Background And Objectives: Electroencephalography (EEG) signals, often termed the letters of the brain, are one of the most cost-effective methods for gathering valuable information about brain activity. This study presents a new explainable feature engineering (XFE) model designed to classify EEG data for violence detection. The primary objective is to assess the classification capability of the proposed XFE model, which uses a next-generation feature extractor, and to obtain interpretable findings for EEG-based violence and stress detection.

Introduction: Psoriatic arthritis (PsA) is a heterogeneous disease with various manifestations such as dactylitis, enthesitis, spondylitis, and skin involvement. Minimal disease activity (MDA) has been successfully used in daily clinical practice and is considered a reasonable treatment target in patients with PsA. In this study, we aimed to evaluate the MDA status and associated factors in patients with PsA in our tertiary referral clinic.

Background: Subcutaneous heparin injections sometimes cause pain, ecchymosis, and hematoma. The prevalence of complications depends on the injection site, technique, and drug absorption. This study investigated the effect of two types of subcutaneous heparin injections on pain, ecchymosis, and hematoma as well as drug absorption rates.

The analysis of gold, which is a precious metal with limited resources, in environmental samples is crucial for the sustainable utilization of natural resources. Therefore, in the present research we have aimed to develop a novel and environmentally friendly bioadsorbent, loaded on silica gel (BB@Si), with outstanding adsorptive properties that can be implemented for quantitative recovery of Au(III) ions the solid phase extraction (SPE) technique. After characterizing the developed adsorbent using FTIR and SEM techniques, we conducted a detailed investigation of the critical parameters that influence the extraction performance of Au(III) ions.

Neuronal ceroid lipofuscinosis type 10 (NCL10) is a rare progressive neurodegenerative disease associated with homozygous or compound heterozygous mutations in the CTSD gene encoding cathepsin D protein. It is classified as congenital, infantile, or juvenile NCL10 according to the age at onset of symptoms. Six cases of juvenile onset NCL10 (JNCL10) have been reported thus far in the literature.

Objective: Headaches are common in children and adolescents as well as in adults. Due to the fact that the primary medical concern for children presenting with headache complaints is the possibility of intracranial pathology, nowadays, imaging methods are frequently used in those patients.

Methods: Retrospective data analysis was performed on the records of children who attended the Pediatric Neurology Outpatient Clinic between June 01, 2018, and December 01, 2018, complaining of headaches.

Background/aims: Radiological imaging advancements have led to a rise in pancreatic cyst diagnoses. Apart from imaging modalities, endoscopic ultrasonography (EUS) is an important method in the diagnosis of pancreatic cysts. The aim of this study is to determine the clinical, laboratory, biochemical, radiological, and endosonographic features of pancreatic cysts and to assess the effectiveness of EUS and computed tomography (CT) in differentiating between neoplastic and nonneoplastic cysts.

Background: Physical activity is essential for maintaining muscle mitochondrial function and aerobic capacity. The molecular mechanisms underlying such protective effects are incompletely understood, in part because it is difficult to separate the effects of disease status and physical activity. We explored the association of human skeletal muscle transcriptomic with four measures of energetics and mitochondria oxidative capacity in healthy individuals.

Background: The incidence of Hepatitis A is increasing worldwide. Yearly classification of Hepatitis A Seroprevalence for different times in different regions of Türkiye allows indirect measurement of year-specific incidence rates of HAV infection and can be considered the best way to define Hepatitis A status. This study aimed to examine the change in the incidence of hepatitis A by systematically evaluating the available data on the seroprevalence of anti-HAV antibodies in the Turkish population.

Background: The incidence of rectal cancer is increasing in the elderly population, yet the safety of surgical interventions in this group, particularly robotic surgery, is still debated. This study aims to investigate the safety and short-term postoperative outcomes of robotic surgery in geriatric patients (aged ≥ 70 years) with rectal cancer.

Patients: Patients diagnosed with rectal cancer and undergoing robotic surgery between March 2021 and September 2023 were divided into two groups based on age: the elderly group (aged ≥ 70 years) and the younger group (aged < 70 years), totaling 108 patients.

Background: Despite the availability of evidence-based treatments for anorexia nervosa (AN), remission rates are moderate, and mortality is high. Olanzapine is used as adjunct therapy for AN in case of insufficient response to first-line treatments, even though the evidence is limited. Its effect on eating disorder (ED) psychopathology, its efficacy and tolerability, and its acceptability and adherence rate are unclear.

Background: Adolescence is the period of human development between childhood and adulthood. Parent-child interaction differs qualitatively in different developmental periods, the development of separate scales sensitive to different age periods regarding parental attitudes is one of the most important issues in this field.

Aim: This study aimed to adapt the Parenting Scale for Adolescents to Turkish culture and to evaluate the psychometric properties of the scale.

Backgruound: This study investigated the risk of frailty in older adults with differentiated thyroid cancer (DTC) and the effect of thyroid- stimulating hormone (TSH) levels on frailty.

Methods: This single-center, cross-sectional study included 70 DTC patients aged ≥60 years with stable TSH levels during the previous year while receiving levothyroxine. Frailty was assessed using the fried frailty phenotype (FFP).

Article Synopsis
  • The study aimed to compare tear function and ocular surface disease (OSD) in glaucoma patients treated with medications in one eye and trabeculectomy surgery in the other.
  • The researchers analyzed data from 19 patients who had surgery at least six months prior, assessing various eye health indicators compared to a control group of healthy individuals.
  • Results indicated that both treatment methods similarly affected OSD, with some improvement noted over time, but neither approach showed a significant advantage over the other regarding the incidence of OSD.
