Quality of life and psychopathology in candidates to bariatric surgery: relationship with BMI class.

PURPOSE: This cross-sectional study aimed at comparing the quality of life (Qol), the prevalence of psychiatric diagnosis and pharmacological treatment in 104 candidates to bariatric surgery according to the degree of obesity (class 2 vs. class ≥ 3 obesity). METHODS: All surgical candidates underwent a detailed psychiatric interview based on DSM-5 criteria, including sociodemographic, clinical, psychological and psychiatric data. Participants completed the Binge Eating Scale (BES) and the 12-Item Short Form Health Survey (SF-12). RESULTS: Overall, bariatric candidates reported a significant impairment in the physical (PCS 38.8 [95% CI 36.2-41.5]) and mental (MCS 42.2 [95% CI 40.4-43.9]) components of Qol compared to population norms (p < 0.001 for both). Subjects with class 2 obesity scored significantly lower in the MCS compared to those with class 3 (38.7 (8.1) vs. 43.6 (8.4), p = 0.008). No other statistically significant differences were found between the two groups in terms of sociodemographic and clinical variables. CONCLUSION: These data support the usefulness of Qol assessment in bariatric candidates as a sensible screening parameter, especially in patients with lower BMI, in whom MCS could identify the need for early psychosocial intervention. LEVEL OF EVIDENCE: Level III, case-control analytic study.

Efficacy of a Disease-Specific Nutritional Support for Pressure Ulcer Healing: A Systematic Review and Meta-Analysis.

OBJECTIVES: The aim of this systematic review was to summarize the evidence on the efficacy of high-calorie, high-protein nutritional formula enriched with arginine, zinc, and antioxidants (disease-specific support) in patients with pressure ulcers (PUs). METHODS: Randomized controlled trials in English published from January 1997 until October 2015 were searched for in electronic databases (EMBASE, Medline, PubMed, and CINAHL). Studies comparing a disease-specific nutritional support (oral supplements or tube feeding) to a control nutritional intervention enabling the satisfaction of energy requirements regardless of the use of high-calorie formula or placebo or no support for at least 4 weeks were considered eligible. Study outcomes were the percentage of change in PU area, complete healing and reduction in the PU area ≥40% at 8 weeks, and the percentage of change in area at 4 weeks. RESULTS: A total of 3 studies could be included in the meta-analysis. Compared with control interventions, formulas enriched with arginine, zinc and antioxidants resulted in significantly higher reduction in ulcer area (-15.7% [95%CI, -29.9, -1.5]; P=0.030; I2=58.6%) and a higher proportion of participants having a 40% or greater reduction in PU size (OR=1.72 [95%CI, 1.04, 2.84]; P=0.033; I2=0.0%) at 8 weeks. A nearly significant difference in complete healing at 8 weeks (OR=1.72 [95%CI, 0.86, 3.45]; P=0.127; I2=0.0%) and the percentage of change in the area at 4 weeks (-7.1% [95%CI, -17.4, 3.3]; P=0.180; I2=0.0%) was also observed. CONCLUSIONS: This systematic review shows that the use of formulas enriched with arginine, zinc and antioxidants as oral supplements and tube feeds for at least 8 weeks are associated with improved PU healing compared with standard formulas.

Anthropometric indices of fat distribution and cardiometabolic risk in Parkinson's disease.

BACKGROUND & AIMS: To investigate the association between anthropometric indices of body fat distribution and cardiometabolic risk factors in a population of Parkinson's disease (PD) patients. METHODS & RESULTS: One hundred and fifty-seven PD patients (57.3% males) were studied measuring: waist circumference (WC), waist-hip ratio (WHR), waist-to-height ratio (WtHR), body fat percentage (BF%) by impedance, fasting glucose, serum lipids. Information was collected also on diabetes, hypertension and metabolic syndrome (MetS). Increased cardiometabolic risk was defined by ≥2 MetS component traits other than abdominal adiposity. In the whole population, prevalence of overweight and obesity were 35.0% and 19.2%, respectively. However, prevalence of MetS and elevated cardiometabolic risk were 14.6% and 18.5%, respectively. Prevalence was similar between genders, with one exception: adverse fat distribution according to WC and WHR was more common in females (P < 0.001). Using a multivariable model (adjustments: age, smoking status and disease duration), indices were highly correlated with BF% in both genders. WC and WtHR were associated with the number of MetS criteria and elevated risk. The only cardiometabolic parameters associated with anthropometric indices were HDL in men and triglycerides in women. After adjusting also for BMI all the associations found with anthropometric indices disappeared. CONCLUSIONS: Despite their correlation with BF%, anthropometric indices of body fat distribution appear to poorly account for the reduced cardiometabolic risk of the PD patient. This finding suggests a low metabolic activity within the adipose tissue. The implications of fat distribution on the cardiometabolic risk of PD patients clearly deserves further investigation.

Clinical features of Parkinson disease when onset of diabetes came first: A case-control study.

OBJECTIVE: Recent literature suggests that diabetes is a risk factor for Parkinson disease (PD). We investigated the clinical features of patients with idiopathic PD (IPD) in whom the onset of diabetes came first. METHODS: We designed a case-control study. From the cohort of all new patients with IPD free of vascular disease (n = 783) admitted and evaluated at our institute over a 3-year period (2007-2010), we included all the patients with a diagnosis of diabetes prior to PD onset (n = 89) and a control group (n = 89) matched (1:1) for gender, body mass index (± 1 kg/m(2)), and duration of PD (± 1 year). The Unified Parkinson's Disease Rating Scale (UPDRS) motor score was the primary endpoint. RESULTS: At study entry, patients with diabetes were similar to controls in terms of most demographic, lifestyle, and general medical features with exception of statins (18% vs 3.4%; p = 0.003). However, diabetes was associated with higher UPDRS motor (22.3 ± 9.0 vs 19.3 ± 7.9; p = 0.019) and activities of daily living (9.7 ± 5.1 vs 8.3 ± 4.3; p = 0.049) scores, more severe Hoehn & Yahr staging (p = 0.009), and higher treatment doses of levodopa (mg/day, 448 ± 265 vs 300 ± 213; p < 0.0001; mg/kg/day, 5.8 ± 4.0 vs 3.8 ± 2.9; p < 0.0001). CONCLUSIONS: Onset of diabetes before the onset of PD appears to be a risk factor for more severe PD symptoms. These findings support the hypothesis that diabetes has a role in the etiopathogenesis of PD. Neurologists should be aware of the potential impact of diabetes on overall PD management.

Validation of the Dutch Eating Behaviour Questionnaire parent version (DEBQ-P) in the Italian population: a screening tool to detect differences in eating behaviour among obese, overweight and normal-weight preadolescents.

OBJECTIVE: To validate the Dutch Eating Behaviour Questionnaire Parent version (DEBQ-P) in the Italian population and investigate the differences in eating behaviour among Italian normal-weight, overweight and obese preadolescents. DESIGN: A cross-sectional validation study. Participants were measured and the approved translation of the questionnaire was administered to their parents. SETTING: : Three school communities in the province of Bergamo, Northern Italy. SUBJECTS: A total of 312 preadolescents (mean age 12.9 y; s.d. 0.8, both sexes) from three secondary schools of the province of Bergamo, Northern Italy, and their parents were invited to participate to the study. Informed written consent was obtained from each subject and their parents. Students were measured and their parents filled in the approved translation of the DEBQ-P. Recruitment was opportunistic and school based. RESULTS: Factor and internal consistency analysis confirmed the factor structure of the DEBQ-P and the high internal consistency of its three scales. Variance analysis showed that eating behaviour of Italian normal-weight, overweight and obese preadolescents differs significantly only in regards to the 'restrained eating' scale (F 19.29, P < 0.001), with overweight and obese scoring higher. CONCLUSIONS: The DEBQ-P can be used for screening projects regarding eating behaviour in the Italian population. The association between restrained eating and weight status was confirmed for both sexes, but the relationship between external eating and emotional overeating and overweight requires further exploration.

[Epidemiology of obesity]. / Epidemiologia del fenomeno obesità.

Overweight and obesity are conditions characterized by weight levels higher than the normal limits for age, sex, and height. Because people stratified for sex and age vary in stature and this influences weight, criteria for being overweight must take height into account: this is defined and set out in WHO guidelines on the basis of Body Mass Index (BMI): weight (kg)/height2 (m2). Obese and overweight individuals are at a greater risk of developing chronic metabolic conditions and general ill health, than those whose weights are within the recommended guidelines. Besides these chronic related conditions for which obesity is a major risk factor incur enormous expenditure. The health hazards of obesity are compounded by the influence of central fat distribution. The disease associations of central fat are present even in people who are not overweight. Waist circumference is a simple measure that gives a very reasonable estimate of the amount of central fat. Data collected in the USA and Europe show a common trend: the increase of obesity and overweight among the adult and children population. Obesity appears to be the result of several factors that interact among them such as: genetic, environment, and behaviour. Current strategies, such as reducing food intake, seem to lead to poor long term outcomes. Management has tended to neglect the unavoidable need to consider obese subjects as chronically ill patients, requiring continuous assistance for active steps to maintain weight loss. Treatments should be multidisciplinary aiming at the achievement of radical changes in the individual's lifestyle. The planning and management of preventive programs for young people such as pubertal children have been disregarded up to now. They require not only attention, but also organization, clear goals and standardized methods. Moreover, a correct education is a key-element of these issues. Our unit has designed for this purpose an observational study aimed to reach a better comprehension of the proportion of ''weight problems'' and eating behavioural patterns in a population of adolescents.
