    Non-alcoholic fatty liver disease (NAFLD), defined as fat accumulation >5% in hepatocytes, may progress to fibrosis or cirrhosis later in life. NAFLD prevalence in adolescents has increased significantly in direct relation with obesity prevalence. Objective: To identify anthropometric variables during the first 10 years of life associated to the risk of developing NAFLD in adolescence. Methods: Longitudinal cohort study 'Growth and Obesity Chilean Cohort Study' (GOCS) consisting of 513 children born in 2002-2003, with yearly anthropometric data collected over a 10 year period. The presence of intra-hepatic fat in the livers of subjects 14-16 years of age was determined using abdominal ultrasound. In addition, elastography was performed on all participants with ultrasound evidence of NAFLD. Results: 9.7% of the participants presented findings compatible with NAFLD. After 2 years of age, obesity significantly and progressively increased the probability of NAFLD occurrence in adolescence. Obesity at 5 years of age was associated with the highest OR for NAFLD, reaching values of 8.91 (95% CI 3.03-16.11). Among participants with NAFLD, those with altered liver elasticity (≥7 Kpa) had greater weight, BMI z-score, waist and hip circumference and altered liver enzymes (p<0.05). Conclusion: The risk of developing NAFLD in adolescence increases progressively with early obesity starting at age 2 years.

    Prehabilitation for Chilean frail elderly people - pre-surgical conditioning protocol - to reduce the length of stay: randomized control trial

    Background: Frail elderly patients have a higher risk of postoperative morbidity and mortality. Prehabilitation is a potential intervention for optimizing postoperative outcomes in frail patients. We studied the impact of a prehabilitation program on length of stay (LOS) in frail elderly patients undergoing elective surgery.Methods: An RCT study was conducted. Frail patients scheduled for elective surgery were randomized to receive either pre-surgical conditioning protocol (PCP) or standard preoperative care. PCP included nursing, anesthetic, and geriatric assessment, nutritional intervention, and physical training for 4-weeks preoperatively. A nurse followed both groups until discharge criteria were met. The primary outcome was postoperative LOS. Secondary outcomes were nutritional status, preoperative frailty status (frailty phenotype-FP) after PCP, and postoperative complications up to three months categorized according to the Clavien-Dindo Classification. Means and medians between the control and intervention groups were compared, with statistical significance set at α=5%.Results: Thirty-four patients were to intervention and Thirty-seven to the control group. In the intervention group, adherence to prehabilitation was 90%. The median LOS after surgery was three days in both groups, without finding statistically significant differences between groups (P=0.754), although there was a trend towards lower LOS in the urologic surgery subgroup. We found a significant reduction in frailty status after PCP (FPpre=2.4±0.5 and FPpost=1.7±0.5, P<0.001). Nutritional status significantly improved in frail patients after prehabilitation (MNAbasal=9.0±2.5 and MNApost=10.6±2.6), P=0.028. The intervention group had less severe postoperative complications, which were not statistically significant.Conclusions: The PCP conducted both in-person and online, for older frail patients undergoing elective colorectal and urological surgery was not associated with shorter LOS. However, frailty status significantly improved after completing PCP.
