Barriers to Adolescents' Adherence to Medical Advice after Metabolic Bariatric Surgery: A Statistical Analysis.

Adolescent obesity has markedly increased worldwide, and metabolic bariatric surgery is an effective treatment option. A major predictor of the outcomes of this procedure is adherence to post-surgery lifestyle changes and medical recommendations. While adolescents generally have more difficulty adhering to medical advice than adults, their failure to do so could adversely affect their physical and psychological health, the cost-effectiveness of medical care, and the results of clinical trials.

Atypical anorexia nervosa: Rethinking the association between target weight and rehospitalization.

Objective: Bodyweight restoration is one of the most important targets in adolescent inpatient treatment of anorexia nervosa (AN). This study examined the association between achieving target weight and rehospitalization in two groups of adolescents with AN and atypical anorexia nervosa (AAN) admitted to a specialized inpatient unit.

Method: Included were 202 adolescent patients hospitalized in a specialized eating disorder unit, 10-18 years old.

Glycemic indices of various foods given to pregnant diabetic subjects.

The applicability of the glycemic index concept in pregnancy has not been established. The postprandial glucose curves were measured for nine foods (glucose, bread, raisins, dates, sweet corn, bananas, oranges, spaghetti, and green peas) in 28 gestational diabetic subjects. Uniform glycemic indices were observed for each food, similar to those reported by others in nonpregnant subjects.

Prognostic factors in breast cancer--a pathological and immunological study of patients with stage 1 breast cancer.

In order to analyze which features determine a poorer prognosis we undertook a study of 91 consecutive patients with pathological Stage I breast cancer operated on at Beth Israel Medical Center (1968-71). Tumor tissue slides were reviewed and features such as: tumor size, histologic type, nuclear grade, lymphocytic and perivenular lymphocytic infiltration, as well as sinus histiocytosis in the lymph nodes removed. Records were reviewed and classified according to age and ethnic background.

Natural host defence during oncogenesis. NK activity and dimethylbenzanthracene carcinogenesis.

In this study we determined the effect of administering the chemical carcinogen dimethylbenzanthracene (DMBA) on NK activity mediated by murine splenocytes. The intragastric administration of six weekly 1-mg doses of DMBA to 2- to 3-month-old mice either following a pituitary graft or not, resulted in a tumor incidence which was higher than 60%. The cellularity of the spleens decreased significantly after the third DMBA feeding and the NK activity of these spleens was selectively suppressed.
