Focusing on young adults constituting the most vulnerable and risky group regarding substance abuse, the present study was carried out in order to examine the relationship between the spiritual well-being levels of university students and their substance abuse proclivity. Having a descriptive and cross sectional design, this study was completed with 250 students studying at a Vocational High School of a university in Türkiye during the academic year 2021-2022. The data collection process was carried out by using the "Personal Information Form," the "Spiritual Well-Being Scale (SWBS)," and the "Substance Use Tendency Scale (SAPS).

Background And Objectives: Fournier's gangrene (FG) is a polymicrobial-induced necrotizing fasciitis that affects the deep and superficial tissues of the perineal, perianal, scrotal, and genital regions. This study aimed to investigate the role of C-reactive protein (CRP)/lymphocyte and neutrophil/lymphocyte ratios, which are objective markers of inflammatory response, in predicting mortality in patients with FG.

Patients And Methods: Seventy-one patients who underwent surgery for FG between 2019 and 2023 were evaluated retrospectively.

The spatiotemporal pattern of surface displacements from large earthquakes provides crucial insights about the deformation of Earth's crust at various scales and the interactions among tectonic plates. However, the lack of extensive and large-scale geodetic networks near such seismic events hinders our thorough understanding of the large-scale crustal deformation resulting from earthquakes. Using Türkiye's extensive and continuous global navigation satellite system (GNSS) network during the moment magnitude 7.

Article Synopsis
  • - The study investigates how obesity and diabetes (type 1 and type 2) impact testosterone levels and oxidative stress in male rats, suggesting that oxidative stress might be key in this relationship.
  • - Male Sprague-Dawley rats were divided into four groups (control, obesity, T1DM, and T2DM) and given different diets and treatments to induce metabolic conditions for comparing testosterone and oxidative stress markers.
  • - Results showed that testosterone levels were significantly lower in T1DM and T2DM rats compared to the control and obesity groups, with oxidative stress markers indicating higher levels of stress in diabetic rats.

Background: The nine item avoidant/restrictive food intake disorder screen (NIAS) is a short and practical assessment tool specific to ARFID with three ARFID phenotypes such as "Picky eating," "Fear," and "Appetite". This study aimed to evaluate the psychometric properties of the Turkish translation of the NIAS parent form and to investigate the relationship between ARFID symptoms and anxiety, depression symptoms, and eating behaviors in a sample of Turkish children.

Method: Parents were asked to provide their children's sociodemographic data and to complete the NIAS, Eating Disorder Examination Questionnaire-Short (EDE-QS), Children's Eating Behavior Questionnaire (CEBQ), and Revised Child Anxiety and Depression Scale (RCADS) scales.

Placenta accreta spectrum (PAS) presents a significant obstetric challenge, associated with considerable maternal and fetal-neonatal morbidity and mortality. Nevertheless, it is imperative to acknowledge that a noteworthy subset of PAS cases remains undetected until the time of delivery, thereby contributing to an augmented incidence of morbidity among the affected individuals. The delayed identification of PAS not only hinders timely intervention but also exacerbates the associated health risks for both the maternal and fetal outcomes.

Article Synopsis
  • The study aimed to assess serum elafin levels and its impact on liver injury due to ischemia-reperfusion in rats, comparing multiple groups with varying reperfusion durations after 30 minutes of induced liver ischemia.
  • Results indicated a significant decrease in elafin levels as reperfusion time increased, with corresponding increases in ischemia-modified albumin (IMA) and total oxidant status (TOS), highlighting deteriorating liver function.
  • Histopathologically, a higher grade of liver injury was associated with lower elafin levels and higher levels of liver enzymes (AST, ALT), indicating a relationship between elafin levels and liver damage severity.

Objective: The aim of the study was to evaluate the protective effects of alpha-lipoic acid (ALA) on the liver, oxidative parameters, and signal peptide-CUB-epidermal growth factor-like domain-containing proteins 1 and 2 (SCUBE-1 and -2) in an experimental cholestatic hepatic ischemia-reperfusion (IR) model.

Materials And Methods: Twenty-four female rats were included in the study and divided into four groups of six rats each. Group 1 was the control group, in which only laparotomy was performed; Group 2 underwent laparotomy and received alpha-lipoic acid (ALA) on a daily basis; bile duct ligation was performed in Group 3; bile duct ligation was performed, and ALA was administered to Group 4.

The cardiac Purkinje system is capable of very rapid burst activity suggestive of its potential role in being a driver of polymorphic ventricular tachycardia (VT) (PMVT) or ventricular fibrillation (VF). It plays a pivotal role, however, not only in the triggering of but also the perpetuation of ventricular arrhythmias. A varying degree of Purkinje-myocardial complicity has been blamed in determining not only the sustained or non-sustained nature of PMVT but also the pleomorphism of the non-sustained runs.

Article Synopsis
  • - The study aimed to assess afamin levels following weight loss in obese patients who underwent laparoscopic sleeve gastrectomy and to explore its relationship with various metabolic markers such as TSH, cholesterol, and insulin levels.
  • - Blood samples were collected from 43 patients before and six months after surgery to compare changes in body mass index (BMI) and other metabolic indicators.
  • - Results showed a decrease in afamin levels post-surgery that was not statistically significant, but there were significant decreases in BMI, cholesterol, and insulin levels, suggesting afamin could serve as a marker for metabolic syndrome related to obesity.

  • This study investigates the levels of heavy metals and antioxidant/oxidant markers in liver tissues from patients with hepatocellular carcinoma (HCC) by comparing samples taken from tumor tissue, surrounding tissue, and tissue farther away.
  • A total of 22 patients were analyzed, showing significant variations in heavy metals (cadmium, lead, zinc) and antioxidants (glutathione peroxidase, superoxide dismutase) across the different tissue locations.
  • The research provides new insights into how heavy metal and antioxidant levels can differ within the same organ, suggesting potential underlying factors still not fully understood in the context of liver cancer.

Pathogen detection is still a challenging issue for public health, especially in food products. A selective preconcentration step is also necessary if the target pathogen concentration is very low or if the sample volume is limited in the analysis. Plate counting (24-48 h) methods should be replaced by novel biosensor systems as an alternative reliable pathogen detection technique.
