Effects of Self-Conditioning Techniques (Self-Hypnosis) in Promoting Weight Loss in Patients with Severe Obesity: A Randomized Controlled Trial.

OBJECTIVE: The usefulness of the rapid-induction techniques of hypnosis as an adjunctive weight-loss treatment has not been defined. This randomized controlled trial evaluated whether self-conditioning techniques (self-hypnosis) added to lifestyle interventions contributed to weight loss (primary outcome), changes in metabolic and inflammatory variables, and quality of life (QoL) improvement (secondary outcomes) in severe obesity. METHODS: Individuals (with BMI = 35-50 kg/m2 ) without organic or psychiatric comorbidity were randomly assigned to the intervention (n = 60) or control arm (n = 60). All received exercise and behavioral recommendations and individualized diets. The intervention consisted of three hypnosis sessions, during which self-hypnosis was taught to increase self-control before eating. Diet, exercise, satiety, QoL, anthropometric measurements, and blood variables were collected and measured at enrollment and at 1 year (trial end). RESULTS: A similar weight loss was observed in the intervention (-6.5 kg) and control (-5.6 kg) arms (ß = -0.45; 95% CI: -3.78 to 2.88; P = 0.79). However, habitual hypnosis users lost more weight (-9.6 kg; ß = -10.2; 95% CI: -14.2 to -6.18; P < 0.001) and greatly reduced their caloric intake (-682.5 kcal; ß = -643.6; 95% CI: -1064.0 to -223.2; P = 0.005) in linear regression models. At trial end, the intervention arm showed lower C-reactive protein values (ß = -2.55; 95% CI: -3.80 to -1.31; P < 0.001), higher satiety (ß = 19.2; 95% CI: 7.71-30.6; P = 0.001), and better QoL (ß = 0.09; 95% CI: 0.02-0.16; P = 0.01). CONCLUSIONS: Self-hypnosis was not associated with differences in weight change but was associated with improved satiety, QoL, and inflammation. Indeed, habitual hypnosis users showed a greater weight loss.

Effects of resveratrol on bone health in type 2 diabetic patients. A double-blind randomized-controlled trial.

OBJECTIVES: Patients with type 2 diabetes (T2DM) are at increased fracture risk. Resveratrol has shown beneficial effects on bone health in few studies. The aim of this trial was to investigate the effects of resveratrol on bone mineral density (BMD) and on calcium metabolism biomarkers in T2DM patients. METHODS: In this double-blind randomized placebo-controlled trial 192 T2DM outpatients were randomized to receive resveratrol 500 mg/day (Resv500 arm), resveratrol 40 mg/day (Resv40 arm) or placebo for 6 months. BMD, bone mineral content (BMC), serum calcium, phosphorus, alkaline phosphatase, and 25-hydroxy vitamin D were measured at baseline and after 6 months. RESULTS: At follow-up, calcium concentrations increased in all patients, while within-group variations in alkaline phosphatase were higher in both resveratrol arms, and 25-hydroxy vitamin D increased in the Resv500 arm only, without between-group differences. Whole-body BMD significantly decreased in the placebo group, while whole-body BMC decreased in both the placebo and Resv40 arms. No significant changes in BMD and BMC values occurred in the Resv500 arm. The adjusted mean differences of change from baseline were significantly different in the Resv500 arm vs placebo for whole-body BMD (0.01 vs -0.03 g/cm2, p = 0.001), whole-body BMC (4.04 vs -58.8 g, p < 0.001), whole-body T-score (0.15 vs -0.26), and serum phosphorus (0.07 vs -0.01 µmol/L, p = 0.002). In subgroup analyses, in Resv500 treated-patients BMD values increased to higher levels in those with lower calcium and 25-hydroxy vitamin D values, and in alcohol drinkers. CONCLUSIONS: Supplementation with 500 mg resveratrol prevented bone density loss in patients with T2DM, in particular, in those with unfavorable conditions at baseline.

Timing of food intake: Sounding the alarm about metabolic impairments? A systematic review.

Growing evidence points to an association between timing of food intake and obesity in humans, raising the question if when to eat matters as much as what and how much to eat. Based on the new definition of obesity as a chronobiological disease, an unusual or late meal timing represent a circadian chronodisruption, leading to metabolic impairments. Preliminary data from cross-sectional and experimental studies suggest that changes in meal timing can influence obesity and success of weight loss therapy, independently from total energy intake, dietary composition and estimated energy expenditure. A systematic review of observational and experimental studies in humans was conducted to explore the link between time of food ingestion, obesity and metabolic alterations. Results confirm that eating time is relevant for obesity and metabolism: observational and experimental studies found an association between meal timing, weight gain, hyperglycemia and diabetes mellitus with benefits deriving from an early intake of food in the day in a wide range of individuals. Herein clinical, future perspectives of chronoprevention and chronotherapy of obesity and type 2 diabetes are also provided. In conclusion, meal timing appears as a new potential target in weight control strategies, and therapeutic strategies should consider this contributor in the prevention of obesity.

Efficacy of a workplace relaxation exercise program on muscle tenderness in a working community with headache and neck pain: a longitudinal, controlled study.

BACKGROUND: Pericranial muscle tenderness shows a remarkable prevalence not only in tension-type headache, but also in migraine, both episodic and chronic. Neck pain is a common disorder and leads to a high rate of work disability; its prevalence increases for headache. AIM: This study aimed at examining the effects of a relaxation exercise programme on pericranial/cervical muscle tenderness in a working community with headache and neck pain. DESIGN: This was a controlled, non-randomized trial. SETTING: The study was carried out in a working community, on the employees of the City of Turin's central and peripheral registry and tax offices. POPULATION: A total of 384 workers were enrolled and divided into two groups: a study group (group 1; 192 subjects) and a control group (group 2; 192 subjects). METHODS: A programme, with relaxation/posture exercises and a visual feedback, was carried out for Group 1 for 6 months and, afterwards, also for group 2 for the same follow-up period throughout. Data on head/neck pain were collected. Standard palpation of pericranial and cervical muscles was done, scoring each patient for Pericranial Muscle Tenderness (PTS) (0-3), Cervical Muscle Tenderness (CTS) (0-3) and a Cumulative Muscle Tenderness (CUM) (0-6). RESULTS: After 6 months from baseline, a significant difference was observed between the groups: i.e. group 1 had an average change from baseline of -0.19 for PTS, -0.2 for CTS and -0.36 for the CUM score - in association with a reduction in headache, neck and shoulder pain. The difference between the groups in PTS, CTS and CUM scores was no longer detectable at the end of the study, after also group 2 performed the programme. CONCLUSIONS: The administration of a workplace relaxation exercise intervention significantly decreased pericranial/cervical muscle tenderness in the working community, in association with head-neck pain benefit. CLINICAL REHABILITATION IMPACT: This relaxation exercise programme was remarkably cost-effective, yielding a relevant benefit on pericranial/cervical muscle tenderness in a working community, at a relatively low cost.
