OBJECTIVE: The goal of this study was to evaluate the effect of two diets (`food combining' or dissociated vs balanced) on body weight and metabolic parameters during a 6-week period in an in-hospital setting. SUBJECTS AND DESIGN: 54 obese patients were randomly assigned to receive diets containing 4.5 MJaday (1100 kcaladay) composed of either 25% protein, 47% carbohydrates and 25% lipids (dissociated diet) or 25% protein, 42% carbohydrates and 31% lipids (balanced diet). Consequently, the two diets were equally low in energy and substrate content (protein, fat and carbohydrate) but widely differed in substrate distribution throughout the day. RESULTS: There was no signi®cant difference in the amount of weight loss in response to dissociated (6.2 AE 0.6 kg) or balanced (7.5 AE 0.4 kg) diets. Furthermore, signi®cant decreases in total body fat and waist-to-hip circumference ratio were seen in both groups, and the magnitude of the changes did not vary as a function of the diet composition. Fasting plasma glucose, insulin, total cholesterol and triacylglycerol concentrations decreased signi®cantly and similarly in patients receiving both diets. Both systolic and diastolic blood pressure values decreased signi®cantly in patients eating balanced diets. The results of this study show that both diets achieved similar weight loss. Total fat weight loss was higher in balanced diets, although differences did not reach statistical signi®cance. Total lean body mass was identically spared in both groups. CONCLUSION: In summary at identical energy intake and similar substrate composition, the dissociated (or`food combining') diet did not bring any additional loss in weight and body fat.
Triple positivity (TP) for antiphospholipid antibodies(aPL) may identify aPL carriers with poorer prognosis. The clinical impact of TP in primary antiphospholipid syndrome(PAPS) remains unclear and further clinical evidences are needed to validate TP as a marker of severity. The aim of this study was to evaluate the impact of TP on the clinical course of PAPS with thrombosis(t-PAPS). We performed a retrospective analysis of a cohort of t-PAPS patients, comparing groups of patients with TP and non-TP profiles according to their demographic, clinical and laboratory features. We included 105 patients with t-PAPS, the median follow-up time of 3.7 years. Twenty-two patients(21%) had TP; the demographic distribution, the presence of cardiovascular risk factors and the site of thrombosis were similar between TP and non-TP patients. The frequency of thrombotic events did not differ between TP and non-TP patients during the study period. Pregnancy morbidities were more frequent in women with t-PAPS and TP than in those with non-TP profile (80% vs. 52.8%, P = 0.05). Patients with t-PAPS and TP presented, at diagnosis, higher dRVVT ratio (median R = 2.44 vs. 1.57, P < 0.0001), higher aCL titer (median = 50UI vs. 35 UI, P < 0.0001), lower C3 levels (median = 1.08 vs. 1.30 mg dL , P = 0.001), lower C4 levels (median = 0.22 vs. 0.25 mg dL , P = 0.05) and higher frequency of positive ANA test (50% vs. 20%, P = 0.008) than patients with t-PAPS and non-TP. Lower-than-normal levels of C3 was independently associated with TP (OR = 5.1, P = 0.02). The presence of TP in patients with t-PAPS was associated with immune derangement, with no effect on the clinical course of the disease.
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.
