Background: The aim of this study was to investigate the effects of a 6-month treatment with intragastric balloon (IGB) on body composition and depressive/anxiety symptoms in obese individuals with metabolic syndrome (MS).
Methods: Fifty patients (aged 18-50 years) with obesity and MS were selected for treatment with IGB for 6 months. Body composition was verified with dual-energy X-ray absorptiometry (DXA) at baseline and right after IGB removal. Anxiety/depressive symptoms were assessed with the Beck Depression Inventory (BDI) and the hospital anxiety and depression scale (HADS) at baseline and after 6 months of treatment.
Results: In total, 39 patients completed the study. After 6 months, there were significant decreases in weight (11.7 ± 9.6 kg, p < 0.0001) and waist circumference (9.3 ± 8.2 cm, p < 0.0001). Weight loss was also demonstrated by DXA and corresponded to decreases of 3.0 ± 3.4% in body fat percentage, 7.53 ± 7.62 kg in total body fat, and 3.70 ± 4.89 kg in lean body mass (p < 0.001 for all comparisons). Depressive symptoms scores decreased by a mean of 4.57 ± 10.6 points when assessed with the BDI (p = 0.002) and 1.82 ± 5.16 points when assessed with the HADS-Depression (p = 0.0345). Anxiety symptoms scores decreased by a mean of 1.84 ± 4.04 points when determined with the HADS-anxiety (p = 0.0066). The decrease in body fat percentage was the parameter that best correlated with improvements in depressive (p = 0.008) and anxiety symptoms (p = 0.014).
Conclusions: In obese individuals with MS, fat mass reduction was associated with short-term improvements in depressive and anxiety symptoms. Registered at ClinicalTrials.gov, NCT01598233.

Background: End-stage renal disease (ESRD) patients frequently experience protein-energy wasting (PEW), which increases their morbidity and mortality rates.
Objective: This study explores the effects of nutritional status and pulmonary function on the short- and long-term mortality of ESRD patients undergoing hemodialysis.
Materials And Methods: 67 consecutive ESRD patients on maintenance hemodialysis were included in the study.

From a current perspective, it is understood that body posture is influenced by individual asymmetries, cultural context, habitual body patterns, etiological factors and psychosocial factors allocated to the individual. Clarifying the musculoskeletal cause that originated the postural alteration is considered the clinical challenge in the treatment of pain or discomfort. Recent studies have shown the influence of changes in body weight on the distribution of plantar pressure and foot pain, emphasizing the importance of understanding these relationships.

Adult males and females have markedly different body composition, energy expenditure, and have different degrees of risk for metabolic diseases. A major aspect of metabolic regulation involves the appropriate storage and disposal of glucose and fatty acids. The use of sophisticated calorimetry, tracer, and imaging techniques have provided insight into the complex metabolism of these substrates showing that the regulation of these processes varies tremendously throughout the day, from the overnight fasting condition to meal ingestion, to the effects of physical activity.

Background: Chest computed tomography (CT) is a valuable tool for diagnosing and predicting the severity of coronavirus disease 2019 (COVID-19) and assessing extrapulmonary organs. Reduced muscle mass and visceral fat accumulation are important features of a body composition phenotype in which obesity and muscle loss coexist, but their relationship with COVID-19 outcomes remains unclear. In this study, we aimed to investigate the association between the erector spinae muscle (ESM) to epicardial adipose tissue (EAT) ratio (ESM/EAT) on chest CT and disease severity in patients with COVID-19.
