Background And Purpose:  Hand fractures are commonly presented in emergency departments, yet diagnostic errors persist, leading to potential complications. The use of artificial intelligence (AI) in fracture detection has shown promise, but research focusing on hand metacarpal and phalangeal fractures remains limited. We aimed to train and evaluate a convolutional neural network (CNN) model to diagnose metacarpal and phalangeal fractures using plain radiographs according to the AO/OTA classification system and custom classifiers.

Article Synopsis
  • Cardiac resynchronization therapy (CRT) improves functional mitral regurgitation (FMR) by coordinating heart muscle segments, especially between papillary muscles, beyond just boosting left ventricular (LV) performance.
  • Eighteen patients with dilated cardiomyopathy underwent tests to measure heart function, and biventricular pacing showed a significant reduction in mitral regurgitation despite some patients showing no change in LV pressure.
  • The study concludes that CRT effectively lowers FMR independently of LV systolic function improvements, highlighting the importance of understanding its mechanisms for better treatment outcomes.

Background: Dissociative amnesia, a disorder characterized by impairments in multiple memory areas, is frequently associated with trauma. Complex post-traumatic stress disorder (CPTSD) is marked by mood dysregulation, negative self-concept, and impaired interpersonal relationships, in addition to the classic symptoms of post-traumatic stress disorder (PTSD). The relationship between CPTSD and dissociative amnesia, as well as whether CPTSD should be considered a dissociative subtype, remains uncertain in the literature.

Background: Twenty-four-hour mean arterial pressure (MAP) is underutilized for the diagnosis and risk assessment of hypertension in clinical settings. The objective of this study is to assess the relation of MAP with systolic and diastolic blood pressure (BP) in diagnosing hypertension on 24-hour ambulatory blood pressure monitoring (ABPM), while also examining its diagnostic effectiveness.

Methods: This retrospective study analyzed 24-hour ABPM of 532 adults.

Article Synopsis
  • Chronic venous insufficiency (CVI) is prevalent among nurses, affecting 65% of the sample studied, and significantly impairs their quality of life and job performance.
  • The study found that factors such as chronic diseases, pregnancy, and being over the age of 26.5 significantly increase the risk of developing CVI, particularly in women.
  • The researchers advocate for the implementation of risk screening and educational programs to prevent CVI among nurses, given its high and concerning prevalence in this healthcare profession.

Objective: The caregiver burden in the relatives of patients with schizophrenia increases mental health problems in patients, complicates coping with the illness for families, and adversely affects the course of the illness. This study aims to investigate the effects of patients' psychopathology severity and cognitive functions on caregiver burden.

Method: Forty-four patients diagnosed with schizophrenia according to DSM-5 and their primary caregivers were included in this cross-sectional descriptive study.

The present study aimed to enhance the survivability of the encapsulated biocomposites of Lactiplantibacillus plantarum AB6-25 and Saccharomyces boulardii T8-3C within the gastrointestinal system (GIS) and during storage period. AB6-25 and T8-3C were individually co-encapsulated using either lactobionic acid (LBA) in Na-alginate (ALG)/demineralized whey powder (DWP) or solely potential probiotics in ALG microcapsules. Free probiotic cells were utilized as the control group.

A novel fermented dairy drink utilizing microbial strains displaying potential probiotic attributes was formulated. The study constituted several experimental cohorts, including AB6-25, isolated from a human stool sample; K2, sourced from a koumiss sample; 3B7, derived from a traditional yogurt sample; and identical lactic acid bacteria (LAB) in combination with yeast ( T8-3C from chicken feces) strains. Two distinct iterations of probiotic-fermented dairy drinks were generated by introducing subcultured microorganism cultures: LAB strains at a concentration of 1% each (designated as combination A) and a blend of LAB strains at 1% each along with T8-3C at 0.

Plastic pollution has threatened biodiversity and human health by shrinking habitats, reducing food quality, and limiting the activities of organisms. Therefore, global interest in discovering novel enzymes capable of degrading plastics has increased considerably. Within this context, the functional metagenomic approach, which allows for unlocking the functional potential of uncultivable microbial biodiversity, was used to discover a plastic-degrading enzyme.

Aquatic invertebrates play a pivotal role in (eco)toxicological assessments because they offer ethical, cost-effective and repeatable testing options. Additionally, their significance in the food chain and their ability to represent diverse aquatic ecosystems make them valuable subjects for (eco)toxicological studies. To ensure consistency and comparability across studies, international (eco)toxicology guidelines have been used to establish standardised methods and protocols for data collection, analysis and interpretation.

Background: Whether the false memory dysfunction in schizophrenia is at the early (encoding, perceptual) or later (retrieval) stages and how delusions affect it remains unclear.

Method: In this study, we examined the perception and memory biases in schizophrenia patients with (Sch/D; n = 31) and without delusions (Sch/Nd; n = 32) and compared them with healthy controls (HCs; n = 35). We used the Deese Roediger McDermott (DRM) Paradigm and the Noise Task to measure the false memory and illusory pattern perception (IPP) biases, respectively.
