Background And Objective: Given the alarming increase in obesity among children undergoing surgery, the main aim of this study was to characterize propofol clearance in a cohort of morbidly obese children and adolescents in relation to their age and body weight characteristics.
Methods: A prospective pharmacokinetic study in morbidly obese children and adolescents undergoing elective surgery was conducted. Serial blood samples were collected and nonlinear mixed-effects modelling using NONMEM® was performed to characterize propofol pharmacokinetics with subsequent evaluation of age and body size descriptors.
Results: Twenty obese and morbidly obese children and adolescents with a mean age of 16 years (range 9-18 years), a mean total body weight (TBW) of 125 kg (range 70-184 kg) and a mean body mass index of 46kg/m (range 31-63 kg/m) were available for pharmacokinetic modelling using a two-compartment pharmacokinetic model (n = 294 propofol concentration measurements). Compared with lean body weight and ideal body weight, TBW proved to be the most predictive covariate for clearance [CL (L/min)= 1.70 × (TBW/70)]. Central volume of distribution, peripheral volume and intercompartmental clearance were 45.2 L, 128 L and 1.75 L/min, respectively, with no predictive covariates identifiable.
Conclusion: In the population pharmacokinetic model for propofol in morbidly obese children and adolescents, TBW proved to be the most significant determinant for clearance. As a result, it is anticipated that dosage of propofol for maintenance of anaesthesia in morbidly obese children and adolescents should be based on TBW using an allometric function.

Recent studies have suggested that the interaction between diet and an individual's genetic predisposition can determine the likelihood of obesity and various metabolic disorders. The current study aimed to examine the association of dietary branched-chain amino acids(BCAAs) and aromatic amino acids(AAAs) with the expression of the leptin and FTO genes in the visceral and subcutaneous adipose tissues of individuals undergoing surgery. This cross-sectional study was conducted on 136 Iranian adults, both men and women, aged ≥18 years.

The effectiveness of bariatric surgery in reducing remnant cholesterol (RC) levels, particularly when obesity is accompanied by elevated glycated hemoglobin (HbA1c), is insufficiently investigated. In this study, we aimed to examine the impacts of two common bariatric procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), as regards their effects on RC and HbA1c levels. Adult morbidly obese subjects were included and assigned to receive either RYGB or SG.

The connections between sarcopenia and various chronic conditions, including type 2 diabetes (T2DM), metabolic syndrome (MetS), and liver disease have been highlighted recently. There is also a high occurrence of sarcopenia in metabolic dysfunction-associated steatotic liver disease (MASLD) patients, who are often disregarded. Both experimental and clinical findings suggest a complex, bidirectional relationship between MASLD and sarcopenia.

Background: MyBFF@school program consisting physical activity in the formed small-sided games (SSG), nutrition and psychology education was designed to combat obesity among schoolchildren in Malaysia. It was expected to improve cardiorespiratory fitness, hence, contributing to obesity treatment and prevention. Thus, we aimed to study the effects of the MyBFF@school program on the cardiorespiratory fitness of overweight and obese primary schoolchildren.

Persistent ascending mesocolon (PAM) is a rare congenital anomaly in ⁓2%-4% of individuals. PAM is associated with various complications, including volvulus of the colon and caecum, bowel perforation, intestinal obstruction, and adhesions. This case is reported on a 48-year-old woman who reported to the Ho Teaching Hospital specialist clinic with a 13-year history of initial painless and reducible paraumbilical swelling.
