Objective: The aim of this study was to assess the short-term effectiveness of an intensive inpatient multidimensional rehabilitation program (MRP), including diet, exercise, and behavioral therapy, in elderly patients with severe obesity. Methods: Forty-four elderly patients (old; age 69.3 ± 3.5 years, BMI 41.9 ± 14.9) were analyzed against 215 younger patients (young; age 48.2 ± 18.5 years, BMI 43.9 ± 9.4), who were used as controls. All patients underwent MRP, based on group therapy guided by a multidisciplinary team (physicians, dietitians, exercise trainers, psychologists). We evaluated changes in anthropometry, cardiovascular risk factors, physical fitness, quality of life, and eating behavior. Results: After 3 weeks of MRP, we observed a reduction in body weight (old –3.8%, young –4.3%), BMI (old –3.9%, young –4.4%), waist circumference (old –3.4%, young –4.1%), total cholesterol (old –14.0%, young –15.0%), and fasting glucose (old –8.3%, young –8.1%), as well as improved performance in the Six-Minute-Walk Test (old +28.7%, young +15.3%), chair-stand test (old +24.8%, young +26.9%), and arm-curl test (old +15.2%, young +27.3%). Significant improvement was registered in all other analyzed domains. Conclusion: Our 3-week MRP provided significant clinical and functional improvement, which was similar between elderly and younger patients with severe obesity. In the long-term, this may be translated into better quality of life, through better management of obesity-associated morbidities and reduced frailty.
The extent of the groin lymph node (LN) dissection for melanoma is still being debated, particularly in the case of micrometastasis (sentinel lymph node positive). We tested the predictive values of the criteria for pelvic dissection currently suggested by national guidelines (number of positive inguinal LN, Cloquet's LN status, and preoperative computed tomographic scan) and the inguinal lymph node ratio (LNR, the ratio between metastatic and excised LNs) to identify patients with pelvic metastasis. We analyzed the predictive values of the above-mentioned criteria in 157 patients who underwent an ilioinguinal dissection, with a focus on their negative predictive values (NPV), which might help identify low-risk patients who might safely avoid pelvic dissection, pelvic dissection reduction, and error rate. Forty-four (26.7%) patients had pelvic LN metastasis. In patients with micrometastasis (17.3% had pelvic LN metastasis), LNR less than 0.1 and Cloquet's LN status achieved clinically relevant NPV (95.7 and 95.5%, respectively) and pelvic dissection reduction (38.4 and 84.6%, respectively), whereas the error rate was 1.7 and 3.0%, respectively. Lower NPVs were observed for number of positive inguinal LNs (88.6%) and computed tomographic scan (78.4%). Accuracy was enhanced when these criteria were considered in multivariable models. In patients with macrometastasis (36.8% had pelvic LN metastasis), LNR and current selection criteria achieved low NPVs and a high error rate. Avoiding pelvic dissection may be safe in sentinel lymph node-positive patients with LNR less than 0.1. The prediction of pelvic metastasis seems to be less accurate for patients with clinically positive LNs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
