RESUMO

OBJECTIVE: This study examined the correlation between smoking habits and psychopathology status, as well as the impact of confounders such as body mass index and gender. METHOD: A total of 134 non-smokers and 152 smokers were enrolled in this study. We measured psychopathology features using Symptom Checklist 90-Revised. We ran logistic regression models testing the smoking-psychopathology association, controlling for body mass index and gender. RESULTS: Smoking was positively correlated with depression, interpersonal sensitivity, hostility, somatization, paranoid ideation and psychoticism (P<0.05). Adjusting for body mass index and gender, the results remained largely unchanged, with a slight independent effect of body mass index. CONCLUSIONS: Our data suggest that smoking is a stronger predictor of psychopathology than body mass index and gender.

RESUMO

OBJECTIVE: Recent research indicates an association between obesity and psychopathology status, the nature of which remains unclear. We evaluated the mediating role of biochemical disturbances in this association among a treatment-seeking sample of obese individuals. METHOD: The study enrolled 143 consecutive overweight and obese individuals (mean age 35±9 y) and 143 normal-weight controls (mean age 34±9 y), matched by age and sex. We measured psychopathology features using the Symptom Checklist 90-Revised (SCL-90-R), a standardized self-evaluation rating scale, and biochemical parameters (plasma cholesterol, triglyceride, and fasting glucose levels) of all participants. Nonlinear regression models were used to estimate the associations among obesity, psychopathology, and biochemical factors. RESULTS: Obesity was associated positively and significantly (P<0.05) with all of the SCL-90-R subscales, with the exception of anxiety and phobic anxiety, as well as with levels of plasma glucose, cholesterol (P<0.01), and triglycerides (P<0.001). Tests for mediation showed that obesity was significantly associated, for the mediators of plasma cholesterol [parameter estimate=-0.033, P<0.05] and triglycerides (parameter estimate=-0.059, P<0.05), only with hostility (parameter estimate=-0.024, P<0.05 and parameter estimate=-0.041, P<0.05, respectively). CONCLUSIONS: Our data suggest that biological substrates that are critically related to obesity, such as dyslipidemia, may mediate, at least in part, the association between obesity and hostility.

RESUMO

BACKGROUND: Recent research indicates an association between obesity and symptoms of psychopathology, the nature of which remains obscure. This study examined the confounding role of behavioral factors on this association. METHOD: One hundred and forty-two overweight/obese subjects who sought treatment for obesity, of both genders (51 males and 91 females), 18 to 64 years old and 139 normal-weight controls of both genders (41 males and 98 females), 18 to 63 years old, were enrolled in this study. We measured psychopathology features, using the Symptom Checklist 90-Revised (SCL-90-R), dietary habits, using the MedDietScore (MDS) questionnaire, and physical activity, using the International Physical Activity Questionnaire (IPAQ). A series of regression models were used to estimate the mediation of dietary patterns and physical activity on the obesity-psychopathology association. RESULTS: The associations between obesity and depression (ß=0.32/ß=0.15), obsession-compulsion (ß=0.03/ß=-0.13), anxiety (ß=-0.25/ß=-0.12), interpersonal sensitivity (ß=0.08/ß=-0.04) and psychoticism (ß=-0.01/ ß=0.025) are accounted for by sedentary behavior and Mediterranean diet. CONCLUSIONS: Our data suggest that modifiable behavioral factors such as sedentary time and dietary patterns positively affect the association between obesity and symptoms of psychopathology.

RESUMO

BACKGROUND AND AIMS: Vinegar has been shown to have a glucose-lowering effect in patients with glucose abnormalities. However, the mechanisms of this effect are still obscure. The aim of this randomised, crossover study was to investigate the effect of vinegar on glucose metabolism in muscle which is the most important tissue for insulin-stimulated glucose disposal. MATERIALS AND METHODS: Eleven subjects with DM2 consumed vinegar or placebo (at random order on two separate days, a week apart), before a mixed meal. Plasma glucose, insulin, triglycerides, nonesterified fatty acids (NEFA), and glycerol were measured preprandially and at 30-60 min for 300 min postprandially from the radial artery and from a forearm vein. Muscle blood flow was measured with strain-gauge plethysmography. Glucose uptake was calculated as the arteriovenous difference of glucose multiplied by blood flow. RESULTS: Vinegar compared to placebo (1) increased forearm glucose uptake (p = 0.0357), (2) decreased plasma glucose (p = 0.0279), insulin (p = 0.0457), and triglycerides (p = 0.0439), and (3) did not change NEFA and glycerol. CONCLUSIONS: In DM2 vinegar reduces postprandial hyperglycaemia, hyperinsulinaemia, and hypertriglyceridaemia without affecting lipolysis. Vinegar's effect on carbohydrate metabolism may be partly accounted for by an increase in glucose uptake, demonstrating an improvement in insulin action in skeletal muscle. This trial is registered with Clinicaltrials.gov NCT02309424.

RESUMO

Gorham-Stout disease is a rare disease of unknown etiology. It is characterized by spontaneous excessive replacement of bone by proliferative non-neoplastic thin-walled lymphatic and/or blood vessels. Histology shows positive stain for the lymphatic endothelial marker LYVE-1 (lymphatic vascular endothelial hyaluronan receptor-1) and many lymphatic growth factors (PDGF-BB, VEGF-C, VEGFR-3). Patients may present with localized pain and/or weakness and radiographic evidence of massive osteolysis involving contiguous bone structures. The disease usually progresses and complications may occur with significant morbidity and mortality. Close monitoring of these patients is recommended. Treatment remains challenging. Surgical treatment has been combined with pre- and postoperative radiation therapy. Drug regimes including bisphosphonates and vitamin D have been used with various results. Currently, the most effective agent is INF-alpha due to its anti-angiogenic effect. The effect of the newer immunomodulatory agents such as the OK-432 remains to be proved.
