Match Strength: 10.622
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: 8.887
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 »

6. Physical Activity and Weight Management Across the Lifespan.
Match Strength: 8.440
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 »

11. Medicare's Search for Effective Obesity Treatments: Diets Are Not the Answer.
Match Strength: 7.499
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 ...

19. Changes in plasma amino Acid levels do not predict satiety and weight loss on diets with modified macronutrient composition.
Match Strength: 6.932
OBJECTIVE: Serotonin mediates satiety in the central nervous system. Brain serotonin content depends on the plasma ratio of tryptophan (Trp) to large neutral amino acids (LNAA) and may be affected by diet composition. We examined whether high-carbohydrate or high-protein diets induce satiety and weight loss by altering plasma concentrations of these amino acids. METHODS: In study 1 (n = 16, BMI = 27.0 +/- 2.3), we compared plasma Trp and LNAA concentrations averaged over 24 h after 2 weeks of consuming isocaloric diets containing either 45 or 65% of total energy as carbohydrate. In study 2 (n ... Read More »

Match Strength: 6.112
The epidemic of obesity is developing faster than the scientific understanding of an efficient way to overcome it, as reflected by the low success rate of short- and long-term weight loss interventions. From a clinical standpoint, this suggests that the body tends to defend a set point of possible genetic origin in the context of a weight-reducing program. As described in this paper, this limited therapeutic success may depend on adaptive thermogenesis, which represents in this case the decrease in energy expenditure (EE) beyond what could be predicted from the changes in fat mass or fat-free ...

A series of three biocompatible P(CL-co-LA)-PEG-P(CL-co-LA) copolymers were synthesized using ring-opening polymerization and characterized by (1)H-NMR, gel permeation chromatography, DSC, dynamic-mechanical analysis, and X-ray diffraction. The number of monomer units was kept constant, while the D,L-LA fraction was varied so as to constitute 0, 30, or 70% of the end segments. The molecular weights were sufficiently high to eventually permit 3D scaffold preparation. A degradation study was carried out over 26 weeks, and the effect of monomer composition on the rate of degradation as well as on ... Read More »

42. Energy Expenditures and Food Intakes of Lactating Women in Guatemala
Match Strength: 5.950
PIP: Total energy expenditures and intakes were simultaneously assessed in 18 lactating women (10 months postpartum) and compared to 6 similarly-sized nonlactating, nonpregnant but multiparious women living in the same rural villag in the Guatemalan highlands. Energy intakes were estimated by the 24-hour recal method for each of 4 consecutive days. Energy expenditures were determined for 2 days by monitoring heart rate throughout the day and relating heart rate to oxygen consumption by individually-determined regression lines. The mean energy intake for the 4 consecutive days was estimated ... Read More »

43. Cystic pancreatic tumors (CPT): Predictors of malignant behavior.
Match Strength: 5.896
BACKGROUND AND OBJECTIVES: Due to widespread use of imaging studies, increasing cystic pancreatic tumor (CPT) cases are being detected. The diagnosis of malignancy in CPT cases requires pancreatectomy. Clinical and laboratory characteristics of CPT may predict underlying malignancy. METHODS: CPT cases treated between 1994 and 2004 at our institution were included. Pseudocysts were excluded. Serous cystadenoma (SCA), mucinous cystadenoma (MCA), intrapapillary mucinous tumor, cystic endocrine tumor, and lymphoepithelial cysts were classified as benign or pre-malignant. Serous cystadenocarcinoma ... Read More »

44. Long-term health and psychosocial outcomes from surgically induced weight loss: results obtained in patients not attending protocolled follow-up visits.
Match Strength: 5.892
Objective:Obesity management is focused at weight loss to obtain health, psychological and social benefits. Outcomes from controlled trials, however, do not reflect the everyday routine practice. Therefore, we aimed to investigate the results from surgically induced weight loss in patients devoid of a protocol-wise follow-up, who were visited at home.Patients and methods:Patients who underwent a vertical banded gastroplasty or a gastric bypass between 1980 and 1997 were eligible. Body weight and height were measured. Patients filled out questionnaires on health status (Nottingham Health ... Read More »

45. Effects of bioactive peptide, valyl-prolyl-proline (VPP), and lactobacillus helveticus fermented milk containing VPP on bone loss in ovariectomized rats.
Match Strength: 5.876
BACKGROUND: Valyl-prolyl-proline (VPP), a bioactive peptide formed during the fermentation with Lactobacillus helveticus LBK-16H (L. helveticus), has been shown to increase bone formation in vitro. The aim of the study was to determine whether VPP and L. helveticus fermented milk prevent bone loss in ovariectomized (OVX) rats. METHODS: During the 12-week intervention study, the OVX rats received VPP in water or L. helveticus fermented milk, containing VPP. Sham-operated rats receiving water acted as controls. The trabecular and cortical bone mineral density were determined by peripheral ... Read More »

46. Hypodipsic hypernatremia after hypothalamic infarct.
Match Strength: 5.802
Background: Hypothalamic hypodipsic syndrome is a rare condition, secondary to a defect in hypothalamic osmoreceptors that leads to impairment of water homeostasis and chronic hyperosmolality. It is frequently associated with defective osmoregulated vasopressin secretion and diabetes insipidus, and the combination results in a greater risk of hypernatremia. The principles of management consist of regulating vasopressin and water intake in relation to changes in daily body weight. Methods and Results: This case report concerns a patient who, after a postoperative cerebral infarction, developed ... Read More »

47. Bariatric surgery for pediatric extreme obesity: now or later?
Match Strength: 5.756
Obesity is a multifactorial disease of epidemic and global proportions that poses the most significant threat to the health of our younger generations. Those who are the most extremely affected bear the largest burden of health problems. In the US, extreme obesity affects approximately 9 million adults and 2 million children, and is associated with both immediate health problems and later health risk, including premature mortality. Present medical and behavioral interventions for extreme obesity in adults and children rarely result in the significant, durable weight loss necessary to improve ... Read More »

48. Influence of TiO(2) and Ag(2)O addition on tricalcium phosphate ceramics.
Match Strength: 5.667
Degradation of implanted ceramics allows for bone in-growth and eventual replacement with natural tissue. Calcium phosphate-based materials have gained the most significant attention because of their excellent biocompatibility and compositional similarities to natural bone. Adding various dopants to these ceramics significantly influences critical properties. In this study, tricalcium phosphate (TCP) compacts were fabricated via uniaxial compression with four compositions: (i) pure TCP, (ii) TCP with 1.0 wt % TiO(2), (iii) TCP with 0.5 wt % Ag(2)O, and (iv) ternary of TCP and 1.0 wt % TiO(2), ...
