Match Strength: 10.483
This issue of the American Psychologist (April 2007) includes two reviews of the literature on the effects of behavioral programs to reduce body weight. One review (T. Mann et al., 2007) concentrates on dietary interventions and finds little evidence that diets are of benefit. The second review (L. H. Powell, J. E. Calvin III, & J. E. Calvin Jr., 2007) concentrates on multicomponent interventions and reports some significant achievements of behavioral interventions. Although the reviews come to different conclusions about the value of supporting weight loss interventions, there appears to be ... Read More »

4. Weight loss during chronic, cervical vagus nerve stimulation in depressed patients with obesity: an observation.
Match Strength: 8.896
Fourteen patients were treated over 2 years with cervical vagus nerve stimulation (VNS) for adjunctive therapy of severe, treatment-resistant depression. Here, we report the serendipitous observation that this treatment was associated with highly significant, gradual weight loss despite the patients' report of not dieting or exercising. The weight loss was proportional to the initial BMI, that is, the more severe the obesity, the greater the weight loss. Weight loss did not correlate with changes in mood symptoms. The vagus nerve carries visceral information to and from the brain; modulation ... Read More »

9. Physical Activity and Weight Management Across the Lifespan.
Match Strength: 8.459
This review discusses key findings and recommendations related to the role of physical activity in weight gain prevention, weight loss, and weight-loss maintenance across the lifespan. For weight gain prevention, epidemiological and clinical studies suggest that regular physical activity is critical, with increases above the recommended 30 min daily for health (e.g., to 45 to 60 min daily) potentially desirable for curtailing weight gain. For weight loss, clinical studies suggest that physical activity interventions alone usually produce only modest results. Combining physical activity with ... Read More »

16. Medicare's Search for Effective Obesity Treatments: Diets Are Not the Answer.
Match Strength: 7.487
The prevalence of obesity and its associated health problems have increased sharply in the past 2 decades. New revisions to Medicare policy will allow funding for obesity treatments of proven efficacy. The authors review studies of the long-term outcomes of calorie-restricting diets to assess whether dieting is an effective treatment for obesity. These studies show that one third to two thirds of dieters regain more weight than they lost on their diets, and these studies likely underestimate the extent to which dieting is counterproductive because of several methodological problems, all of ...

43. Decreased basal levels of glucagon-like peptide-1 after weight loss in obese subjects.
Match Strength: 6.439
OBJECTIVE: Basal glucagon-like peptide-1 (GLP-1) concentrations seem to be attenuated in obese subjects, although statistical significance is unclear. Only a few studies have investigated the effect of weight reduction on GLP-1 concentrations and have found unclear results. The aim of the present study was to determine whether subjects who lose weight on a hypocaloric diet experience the same change in circulating GLP-1 levels as subjects who do not lose weight. MATERIAL AND METHODS: A population of 99 obese nondiabetic outpatients was analyzed in a prospective way. Weight and blood pressure ... Read More »

45. CLINICAL Review # : low body weight mediates the relationship between HIV infection and low bone mineral density: a meta-analysis.
Match Strength: 6.415
CONTEXT: HIV infection has been associated with low bone mineral density (BMD) in many cross-sectional studies, although longitudinal studies have not demonstrated accelerated bone loss. The cross-sectional studies may have been confounded by the failure to control for low body weight in HIV-infected patients. OBJECTIVE: Our objective was to determine whether low body weight might explain the association of HIV infection with low BMD. DATA SOURCES: MEDLINE and EMBASE were searched for English language studies published from 1966 to March 2007, and conference abstracts prior to 2007 were hand ... Read More »

46. Results of a pilot study of the effects of celecoxib on cancer cachexia in patients with cancer of the head, neck, and gastrointestinal tract.
Match Strength: 6.376
BACKGROUND.: Animal models suggest that cyclooxygenase-2 (COX-2) inhibitors may be beneficial in suppressing cancer cachexia. We investigated the effect of short-course celecoxib on body composition, inflammation, and quality of life (QOL) in patients with cancer cachexia in a phase II clinical pilot trial. METHODS.: Eleven cachectic patients with head and neck or gastrointestinal cancer were randomly assigned to receive placebo or celecoxib for 21 days while awaiting the initiation of cancer therapy. Body composition, resting energy expenditure, QOL, physical function, and inflammatory ... Read More »

47. Birth Characteristics, Maternal Reproductive History, and the Risk of Infant Leukemia: A Report from the Children's Oncology Group.
Match Strength: 6.332
Leukemias with MLL gene rearrangements predominate in infants (<1 year of age), but not in older children, and may have a distinct etiology. High birth weight, higher birth order, and prior fetal loss have, with varying consistency, been associated with infant leukemia, but no studies have reported results with respect to MLL status. Here, we report for the first time such an analysis. During 1999 to 2003, mothers of 240 incident cases (113 MLL(+), 80 MLL(-), and 47 indeterminate) and 255 random digit dialed controls completed a telephone interview. Odds ratios and 95% confidence intervals ... Read More »

48. Analysis of Pancreatic Adenocarcinoma Tumor Staging and Resection according to Previous Body Mass Index and Diabetes Duration.
Match Strength: 6.329
Background/Aims: Obesity and diabetes mellitus (DM) are associated with pancreatic cancer. The present study evaluated tumor staging and resectionof pancreatic adenocarcinoma (PaC) according to previous Body Mass Index (BMI), BMI on admission and DM duration. Methods: A retrospective analysis of 151 consecutive patients with PaC was performed: 73 were evaluated according to BMI preceding tumor-related weight loss and BMI on admission; 118 according to DM diagnosis; and 38 were assessed according to DM duration (less than 1 year [recent-onset] versus more than 2 years [long-standing]). Results: ... Read More »

49. Randomized controlled trial comparing a low-fat diet with a weight-reduction diet in breast cancer-related lymphedema.
Match Strength: 6.304
BACKGROUND: Obesity is considered a risk factor for lymphedema of the arm resulting from breast cancer treatment (BCRL) as well as a poor prognostic factor in response to lymphedema treatment. The aim of the study was to compare the effect of 2 dietary interventions on excess arm volume in BCRL. METHODS: A total of 64 women with BCRL were randomized to 1 of 3 groups for 24 weeks: 1) weight reduction through reduced energy intake; 2) low-fat diet with no change in energy intake (isoenergetic); 3) control group with no dietary change from habitual intake. RESULTS: The primary outcome measure was ... Read More »

50. Chronic clozapine treatment in female rats does not induce weight gain or metabolic abnormalities but enhances adiposity: Implications for animal models of antipsychotic-induced weight gain.
Match Strength: 6.228
The ability of clozapine to induce weight gain in female rats was investigated in three studies with progressively lowered doses of clozapine. In an initial preliminary high dose study, clozapine at 6 and 12 mg/kg (i.p., b.i.d.) was found to induce weight loss. In a subsequent intermediate dose study, we obtained no evidence for clozapine-induced weight gain despite using identical procedures and doses of clozapine (1-4 mg/kg, i.p., b.i.d.) with which we have observed olanzapine-induced weight gain, hyperphagia, enhanced adiposity and metabolic changes [Cooper G, Pickavance L, Wilding J, ...
