Purpose: Radiation therapy with chemotherapy (CCR) is currently the gold standard treatment for nasopharyngeal carcinoma (NPC). Anatomical changes are mainly due to weight loss. Our prospective study aimed to evaluate the nutritional status and the quality of weight loss in our patients to adapt the subsequent nutritional management of patients during treatment for NPC.
Patients And Methods: A prospective, single-center study of 27 patients with non-metastatic NPC treated in our oncology radiotherapy department between August 2020 and March 2021. Data from interrogation, physical examination, and bioelectrical impedancemetry (weight [W], body mass index [BMI], fat index [GI], fat mass [FM], and fat-free mass (FFM]) were collected at the beginning, the mid, and the end of treatment.
Results: Weight loss from mid to end of treatment (median=-4kg [-9.4; -0.9]) was greater than that from baseline to mid-treatment (median=-2.9kg [-8.8; 1.8]) (P=0.016). Weight loss during the entire treatment was -6.2kg [-15.6; -2.5] (8.4%). The losses of FM were identical between the beginning-mid treatment and the mid-end treatment; they were respectively -1.4kg [-8.5; 4.2] and -1.4kg [-8.2; 7.8] (P=0.4). FFM losses between the mid- and the end of treatment (-2.5kg [-27.8; 0.5]) were greater than those between baseline and mid-treatment (-1.1kg [-7.1; 4.7]) (P=0.014). Median FFM loss during treatment was -3.6kg [-28.1; 2.6]).
Conclusion: The results of our study show that weight loss during CCR for NPC is complex and is not just about loss but about a disruption of body composition. Regular follow-ups by nutritionists are required to prevent denutrition during treatment.

Thermogravimetry coupled with simultaneous evolved gas analysis by mass spectrometry was used for discerning organic compounds released during the thermal degradation of paint whose chemical compositions are not readily accessible. Thermogravimetric analyses up to 600°C revealed distinct degradation patterns under inert and oxidative conditions. Significant degradation of paint initiates at around 360°C and concludes at 500°C in a nitrogen atmosphere.

Obesity is related to a wide variety of medical and psychological comorbidities which has short- and long-term effects on children's mental health. One of the most significant ones is depression. Thus, the current study utilized a descriptive methodology to explore the differences in depressive symptoms among overweight, obese, and normal-weight Palestinian children and adolescents.

Introduction: Obesity, affecting 38% of adults globally, carries economic burdens and health risks like cardiovascular disease and diabetes. Weight-loss programs often face challenges due to stigma and poor body image, impacting individuals' quality of life. Research on interventions targeting weight stigma is lacking, emphasizing the need for comprehensive approaches addressing psychological and behavioral aspects for effective care.

This review aimed to analyze direct comparative studies for semaglutide versus other GLP-1 RA (liraglutide and efinopegdutide) in facilitating weight loss and evaluating adverse events in patients with obesity. A systematic search following the guidelines established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was performed in PubMed, Embase, and Cochrane Library for direct comparative studies comparing semaglutide with other GLP-1 RA on weight loss in patients with obesity.

Introduction: This article presents the fourth detection of macroscopic cystic lesions due to sarcocystosis in domestic pigs during routine meat inspection worldwide, and the first molecular detection of in a domestic pig in Poland. Pigs can become intermediate hosts for by accidental ingestion of oocysts or sporocysts present in food or water contaminated by the faeces of canids (definitive hosts).
Material And Methods: The affected swine showed no clinical symptoms such as weight loss, dermatitis or dyspnoea suggesting sarcocystosis.
