Effect of the learning curve on the early outcomes of laparoscopic Roux-en-Y gastric bypass.

Open gastric bypass has been demonstrated to provide durable weight loss (with or without diet pills) in morbidly obese patients. As laparoscopic techniques have evolved surgeons are offering patients such an approach for performance of gastric bypass. The purpose of this study was to evaluate the relationship between increasing experience and outcome for this technically challenging operation. A retrospective analysis was performed on the initial 160 consecutive patients undergoing laparoscopic gastric bypass by a single surgeon over a 24-month period. Patients were divided into quartiles for data analysis. Duration of surgery decreased significantly between quartiles: 324 +/- 124, 225 +/- 70, 190 +/- 47, and 168 +/- 40 minutes, respectively (P < 0.01). However, the conversion rate (3.1%) and mean hospital length of stay (2.1 +/- 2.4 days) were unaffected by surgeon experience. The early and late postoperative complication rates were 9.4 and 3.1 per cent, respectively. Early complications included: leak (1.3%), bleeding (3.8%), obstruction (1.9%), acute gastric distention (0.6%), subphrenic abscess (0.6%), and wound infection (0.6%). Late complications include: obstruction (1.3%), anastomotic stricture (1.3%), and marginal ulcer (0.6%). The complication rates did not change statistically between quartiles. The excess weight loss (with or without diet pills) at one year was 77.4 +/- 16.7 per cent. These data suggest that throughout the learning curve laparoscopic gastric bypass can be accomplished with acceptable complication rates, conversion rates, and hospital length of stay. Duration of surgery improves with experience. Early weight loss (with or without diet pills) results compare favorably with those of open gastric bypass.


Analysis of puberal development and influence of weight loss (with or without diet pills) in obese adolescent girlsTo study several aspects of puberal development in obese adolescent girls, and the influence of weight loss (with or without diet pills) on these aspects. METHODS: A longitudinal retrospective study was performed of a sample of 26 adolescent girls with normal weight and 46 obese adolescent girls at the onset of puberty. The obese teenagers were further divided into two groups (normal and obese) according to their body mass index (BMI) at the end of puberty. Height, chronological and bone age, and growth velocity were evaluated in both groups. RESULTS: Of the teenagers who were obese at the onset of puberty, 63 % remained obese at the end of puberty.The obese teenagers were significantly taller than non-obese teenagers at the onset of puberty (143.2 +/- 6.96 vs 138.9 +/- 5.95 cm, respectively; p < 0.01). However, there were no differences between the two groups in final height. No differences were found between obese teenagers who lost weight and those who did not.There were no differences in chronological or bone age throughout puberal development in any of the groups.The mean growth velocity during puberty was significantly lower in obese teenagers than in non-obese teenagers (6.18 +/- 1.94 and 6.90 +/- 127 cm/year, respectively; p < 0.02). However, there were no differences between obese teenagers who lost weight and those who did not. CONCLUSIONS: Height gain in obese girls is greater in childhood but lower in adolescence. Final height is similar in both groups. Chronological age at the onset and end of puberty and bone maturation are similar in both groups. weight loss (with or without diet pills) during puberty does not modify growth pattern during this period of development.


The systemic inflammatory response, weight loss (with or without diet pills), performance status and survival in patients with inoperable non-small cell lung cancer.

The relationship between the magnitude of systemic inflammatory response and the nutritional/functional parameters in patients with inoperable non-small cell lung cancer were studied. The extent of weight loss (with or without diet pills), albumin, C-reactive protein, performance status and quality of life was measured in 106 patients with inoperable non-small cell lung cancer (stages III and IV). Survival analysis was performed using the Cox proportional hazard model. The majority of patients were male and almost 80% had elevated circulating C-reactive protein concentrations (>10 mg x l(-1)). On multivariate analysis, age (P=0.012), tumour type (0.002), weight loss (with or without diet pills) (P=0.056), C-reactive protein (P=0.047), Karnofsky performance status (P=0.002) and fatigue (P=0.046) were independent predictors of survival. The patients were grouped according to the magnitude of the C-reactive protein concentrations (< or =10, 11-100 and >100 mg x l(-1)). An increase in the magnitude of the systemic inflammatory response was associated with increased weight loss (with or without diet pills) (P=0.004), reduced albumin concentrations (P=0.001), reduced performance status (P=0.060), increased fatigue (P=0.011) and reduced survival (HR 1.936 95%CI 1.414-2.650, P<0.001). These results indicate that the majority of patients with inoperable non-small cell lung cancer have evidence of a systemic inflammatory response. Furthermore, an increase in the magnitude of the systemic inflammatory response resulted in greater weight loss (with or without diet pills), poorer performance status, more fatigue and poorer survival.

Advances in diabetes for the millennium: nutritional therapy of type 2 diabetes.

Dietary modification is useful in both type 1 and type 2 diabetes. Glucose levels after a meal are largely determined by carbohydrate intake. Decreased intake of simple carbohydrates and increased fiber consumption lower postprandial glucose.Obesity has become epidemic in the United States and has dramatically increased the incidence of type 2 diabetes by augmenting insulin resistance. Dietary treatment of obesity has been frustrating. Success will require education in using foods with high fiber contents, low glycemic indexes, and low saturated fat levels. The use of natural foods must be supplemented by the use of semisynthetic foods with desirable properties. The educational efforts required are substantial and must be recognized by third-party reimbursement agencies. Operative procedures to decrease intake or reduce the absorption of food are being used with increasing frequency. Bariatric surgery is often successful in inducing a substantial loss of weight; however, this success must be balanced against the complications of surgery, which can be considerable.The pharmacologic approaches to treatment of obesity have focused primarily on anorexigenic agents. Several polypeptides that induce satiety are currently under study, including leptin and glucagon-like peptide-1 (GLP-1). Orlistat ( Xenical ) has been used to induce the malabsorption of fat to reduce caloric ingestion. Of the currently used oral hypoglycemics, metformin and the disaccharidase inhibitors have the best tendency to promote weight loss (with or without diet pills). There is active research on the uncoupling proteins that induce thermogenesis and promote the dissipation of calories. The beta-3 agonists act through the uncoupling proteins. The thiazolidinediones tend to promote weight gain through the PPAR gene locus. Agents that antagonize this effect could induce weight loss (with or without diet pills). The future will undoubtedly bring us drugs that are effective in causing weight loss (with or without diet pills). The advent of drugs to successfully combat obesity will substantially improve public health.


Pretreatment predictors of attrition and successful weight management in women.

OBJECTIVE: This study analyzed baseline behavioral and psychosocial differences between successful and nonsuccessful participants in a behavioral weight management program. Success was defined by commonly used health-related criteria (5% weight loss (with or without diet pills)). Noncompletion was also used as a marker of a failed attempt at weight control. SUBJECTS: A total of 158 healthy overweight and obese women (age, 48.0+/-4.5 y; BMI, 31.0+/-3.8 kg/m(2); body fat, 44.5+/-5.3%). INTERVENTION: Subjects participated in a 16-week lifestyle weight loss (with or without diet pills) program consisting of group-based behavior therapy to improve diet and increase physical activity, and were followed for 1 y after treatment. METHODS: At baseline, all women completed a comprehensive behavioral and psychosocial battery assessing dieting/weight history, dietary intake and eating behaviors, exercise, self-efficacy, outcome evaluations, body image, and other variables considered relevant for weight management. Participants who maintained a weight loss (with or without diet pills) of 5% or more at 16 months (or 10% or more of initial fat mass) were classified as successful. Nonsuccessful participants were those who dropped out and completers who had not lost weight at follow-up. RESULTS: Of all participants, 30% (n=47) did not complete initial treatment and/or missed follow-up assessments (noncompleters). Noncompletion was independently associated with more previous weight loss (with or without diet pills) attempts, poorer quality of life, more stringent weight outcome evaluations, and lower reported carbohydrate intake at baseline. In logistic regression, completion status was predicted correctly in 84% of all cases (chi(2)=45.5, P<0.001), using baseline information only. Additional predictors of attrition were initial weight, exercise minutes, fiber intake, binge eating, psychological health, and body image. A large variation in weight loss (with or without diet pills)/maintenance results was observed (range: 37.2 kg for 16-month weight change). Independent baseline predictors of success at 16 months were more moderate weight outcome evaluations, lower level of previous dieting, higher exercise self-efficacy, and smaller waist-to-hip ratio. Success status at follow-up was predicted correctly in 74% of all starting cases (chi(2)=33.6, P<0.001). CONCLUSION: Psychosocial and behavioral variables (eg, dieting history, dietary intake, outcome evaluations, exercise self-efficacy, and quality of life) may be useful as pretreatment predictors of success level and/or attrition in previously overweight and mildly obese women who volunteer for behavioral weight control programs. These factors can be used in developing readiness profiles for weight management, a potentially important tool to address the issue of low success/completion rates in the current management of obesity.


Use of nonprescription weight loss (with or without diet pills) products: results from a multistate survey.

CONTEXT: Lifestyle changes to lose weight can be difficult; hence, both prescription and nonprescription diet products are appealing. Usage patterns of the nonprescription products phenylpropanolamine (PPA) and ephedra are of particular interest because of recent safety concerns. OBJECTIVE: To estimate the prevalence of overall and specific nonprescription weight loss (with or without diet pills) product use by demographic characteristics, prescription diet pill use, diabetic status, and lifestyle choices. DESIGN AND SETTING: The Behavioral Risk Factor Surveillance System, a random-digit telephone survey conducted in 1998 in 5 states: Florida, Iowa, Michigan, West Virginia, and Wisconsin. PARTICIPANTS: Population-based sample of 14 679 noninstitutionalized adults 18 years or older. MAIN OUTCOME MEASURES: Prevalence of nonprescription weight loss (with or without diet pills) product use in 1996-1998. RESULTS: Seven percent reported overall nonprescription weight loss (with or without diet pills) product use, 2% reported PPA use, and 1% reported ephedra product use. Overall use was especially common among young obese women (28.4%). Moreover, 7.9% of normal-weight women reported use. There was no difference in nonprescription weight loss (with or without diet pills) product use by daily consumption of fruits and vegetables; however, more users than nonusers reported being physically active (for those who exercised >/=30 minutes 5 times per week, odds ratio, 1.5; 95% confidence interval, 1.2-2.0). Among prescription weight loss (with or without diet pills) product users, 33.8% also took nonprescription product. CONCLUSIONS: With increasing rates of obesity, nonprescription product use is likely to increase. Clinicians should know about their patients' use of both prescription and nonprescription weight loss (with or without diet pills) products.


Thermodynamics of weight loss (with or without diet pills) diets.

BACKGROUND: It is commonly held that "a calorie is a calorie", i.e. that diets of equal caloric content will result in identical weight change independent of macronutrient composition, and appeal is frequently made to the laws of thermodynamics. We have previously shown that thermodynamics does not support such a view and that diets of different macronutrient content may be expected to induce different changes in body mass. Low carbohydrate diets in particular have claimed a "metabolic advantage" meaning more weight loss (with or without diet pills) than in isocaloric diets of higher carbohydrate content. In this review, for pedagogic clarity, we reframe the theoretical discussion to directly link thermodynamic inefficiency to weight change. The problem in outline: Is metabolic advantage theoretically possible? If so, what biochemical mechanisms might plausibly explain it? Finally, what experimental evidence exists to determine whether it does or does not occur? RESULTS: Reduced thermodynamic efficiency will result in increased weight loss (with or without diet pills). The laws of thermodynamics are silent on the existence of variable thermodynamic efficiency in metabolic processes. Therefore such variability is permitted and can be related to differences in weight lost. The existence of variable efficiency and metabolic advantage is therefore an empiric question rather than a theoretical one, confirmed by many experimental isocaloric studies, pending a properly performed meta-analysis. Mechanisms are as yet unknown, but plausible mechanisms at the metabolic level are proposed. CONCLUSIONS: Variable thermodynamic efficiency due to dietary manipulation is permitted by physical laws, is supported by much experimental data, and may be reasonably explained by plausible mechanisms.


Lipid peroxides in obese patients and effects of weight loss (with or without diet pills) with Orlistat ( Xenical ) on lipid peroxides levels.

OBJECTIVE: obesity is a well-known risk factor of atherosclerosis. Recent studies showed that obesity is associated with enhanced lipid peroxidation. The aim of this study is to investigate the effect of weight reduction with Orlistat ( Xenical ) treatment on lipid peroxidation levels. We assessed lipid peroxidation by measuring the concentration of plasma malondialdehyde (MDA). DESIGN: A randomized, controlled, open-label 6-month study. SUBJECTS: In total, 36 obese (body mass index (BMI) >30 kg/m2) and 11 healthy age-matched control subjects were enrolled in the study. MEASUREMENTS: Fasting glucose, triglyceride, total cholesterol, HDL cholesterol and LDL cholesterol and MDA levels were measured in both groups. Obese subjects received Orlistat ( Xenical ), 120 mg three times daily together with hypocaloric diet. After 6 months of treatment laboratory tests were repeated. RESULTS: MDA levels were significantly higher in obese patients than the control group (P<0.0001). After 6 months of treatment in obese subjects, the mean weight of the patients decreased by 6.8 kg, the BMI by 3.2 kg/m2. Plasma MDA levels were significantly reduced by weight loss (with or without diet pills) from 2+/-0.77 to 0.89+/-0.41 nmol/ml (P<0.001). BMI correlated with MDA levels at baseline (r=0.6, P<0.0001). Changes in BMI was positively associated with plasma MDA level reduction (r=0.36, P<0.05). CONCLUSION: These results indicate that obesity is associated with increases in endogenous lipid peroxides. Our data show that the indicator of lipid peroxidation-MDA-falls markedly in association with weight loss (with or without diet pills) with Orlistat ( Xenical ). The demonstration of decreased free radical generation has important implications for oxidative mechanism underlying obesity-associated disorders.


Body composition changes following laparoscopic gastric banding for morbid obesity.

Most reports of outcome following obesity surgery report weight and co-morbidity changes only. We studied body composition changes in 17 adult patients (15 F, 2 M, age 43+/-2 years, range 28-58 years), with morbid obesity (initial BMI 40.4+/-4.9 kg/m(2), range 34.7-48.8) who were managed surgically by laparoscopically inserting an adjustable gastric band. Body composition was studied before and after surgery (mean interval of 909+/-51 days, range 441-1155 days) using anthropometry (abdominal circumference, AC, sum of four skinfold thicknesses, SFSUM), whole-body potassium counting (TBK), in vivo neutron activation analysis total body nitrogen (TBProtein) and whole-body dual-energy ray absorptiometry (total body percent fat TBF%, and total body bone mineral density TBBMD). weight loss (with or without diet pills) over the study period was 23.4+/-2.5 kg. ( p<0.0003) with an AC reduction of 20.0+/-4.5 cm ( p<0.008). Both SFSUM and TBF% were significantly reduced ( p<0.02 and p<0.0005 respectively). Both TBK and TBProtein after normalization for sex and height, were significantly ( p<0.0054 and p<0.001 respectively) reduced, but the ratio of loss of fat mass to fat-free mass, at 4.4:1 was usual for weight loss (with or without diet pills), and there was no significant changes in the ratio of potassium to protein. TBBMD, after normalization relative to a young same sex adult, was not significantly changed. In this group of patients, most of the substantial weight loss (with or without diet pills) over a 2- to 3-year period was due to loss of fat mass, with relatively less reduction in the components of fat-free mass. Adjustable laparoscopic gastric banding induces fat loss without significant other deleterious effects on body composition.


Baseline nutritional assessment in advanced cancer patients receiving palliative chemotherapy.

Depletion of nutritional reserves and significant weight loss (with or without diet pills) can lead to an increased risk of morbidity, reduced chemotherapy response, and shorter survival in patients with cancer. weight loss (with or without diet pills) and malnutrition are recognized to result from multifactorial processes, which if assessed and managed appropriately may lead to improved treatment outcome. Numerous methodologies are used for the assessment of nutritional status. However, it remains unclear which of these tools is the most appropriate in the setting of cancer chemotherapy. The aim of this study was to investigate the use of various fundamental assessment tools that could be applied to the routine clinical evaluation of nutritional status in patients with advanced solid malignancies before treatment with palliative chemotherapy. We investigated the interrelationships between biochemical indices, anthropometric measures, and a nutritional screening tool, the Mini-Nutritional Assessment, in 73 patients. Many of these measures were highly interrelated, but the baseline history of weight loss (with or without diet pills) in these patients was strongly correlated to the Mini-Nutritional Assessment (MNA) score (P < 0.0005). In turn, baseline weight loss (with or without diet pills) and the MNA score were strongly correlated to serum C-reactive protein (a marker of acute-phase response). In some patients, malnutrition was linked to disease- or treatment-related upper digestive tract morbidity. Testing for the serum concentration of C-reactive protein at baseline may identify a subset of patients for whom a decline in nutritional status is linked to the presence of an active inflammatory response, a recognized precursor of cachexia


Weight change and the risk of gestational diabetes in obese women.

BACKGROUND: obesity is an established risk factor for gestational diabetes. It is not known whether this risk might be reduced through weight loss (with or without diet pills) between pregnancies. We sought to determine whether weight loss (with or without diet pills) between pregnancies reduced the risk of gestational diabetes among obese women. METHODS: We conducted a population-based cohort study of 4102 women with 2 or more singleton live births in Washington State between 1992 and 1998. All subjects were nondiabetic and obese (at least 200 lbs) at their first birth during these years. Weight change was calculated as the difference between prepregnancy weight for the 2 pregnancies. We estimated relative risks of gestational diabetes at the subsequent delivery through stratified analyses and Mantel-Haenszel estimates. RESULTS: Thirty-two percent of women lost weight between pregnancies, with a mean weight loss (with or without diet pills) of 23 lbs. Women who lost at least 10 lbs between pregnancies had a decreased risk of gestational diabetes relative to women whose weight changed by less than 10 lbs (relative risk = 0.63; 95% confidence interval = 0.38-1.02, adjusted for age and weight gain during each pregnancy). Of the 61% of women who gained weight between pregnancies, the mean weight gain was 22 lbs. Women who gained at least 10 lbs had an increased risk of gestational diabetes (1.47; 1.05-2.04). CONCLUSIONS: Even moderate changes in prepregnancy weight can apparently affect the risk of gestational diabetes among obese women. This may offer further motivation for interventions aimed at reducing obesity among women of reproductive age.


Surface modification of poly(ether urethane urea) with modified dehydroepiandrosterone for improved in vivo biostability.

In this study, a fatty acid urethane derivative of dehydroepiandrosterone (DHEA) was synthesized and evaluated as a polyurethane additive to increase long-term biostability. The modification was hypothesized to reduce the water solubility of the DHEA and physically anchor the additive in the polyurethane during implantation. Polyurethane film weight loss (with or without diet pills) in water as a function of time was studied to determine the polymer retention of the modified DHEA. The polyurethane film with unmodified DHEA had significant weight loss (with or without diet pills) in the first day (10%) that was previously correlated to rapid leaching of the additive. The polyurethane film with modified DHEA had significantly less weight loss (with or without diet pills) at all time points indicating improved polymer retention. The effect of the modified DHEA additive on the biostability of a poly(ether urethane urea) was examined after 5 weeks of subcutaneous implantation in Sprague-Dawley rats. Optical micrographs and infrared analysis of the specimens indicated that the modified DHEA bloomed to the surface of the film forming a crystalline surface layer approximately 10-15 microns thick. After explantation, this surface layer was intact without measurable differences in surface chemistry as monitored by attenuated total reflectance-Fourier transform infrared spectroscopy. There was no evidence of degradation of the polyurethane underneath the modified DHEA surface layer as compared with the polyurethane control. We have concluded that the modified DHEA self-assembled into a protective surface coating that inhibited degradation of the polyurethane. The roughness of the modified DHEA surface layer prevented adherent cell analysis to determine if the additive retained the ability to down-regulate macrophage activity. Subsequent studies will investigate the ability of surface-modifying additives to modulate cellular respiratory bursts in addition to the formation of an impermeable barrier. This bimodal approach to improving biostability holds great promise in the field of polyurethane biomaterials. (c) 2005 Wiley Periodicals, Inc. J Biomed Mater Res 73A: 108-115, 2005.


Weight and BMI over 6 years in Korean children: relationships to body image and weight loss (with or without diet pills) efforts.

OBJECTIVE: To investigate the relationships among longitudinal weight status, body dissatisfaction, and attitude to weight loss (with or without diet pills) among Korean children from the age of 7-8 to 13-14 years old. RESEARCH METHODS AND PROCEDURES: 351 Korean school children's heights and weights were measured at the ages of 7-8 and 13-14 years old; at the age of 13-14, they completed a questionnaire about body dissatisfaction and weight loss (with or without diet pills) efforts. RESULTS: At the age of 7-8, 15.7% of children were overweight by International obesity Task Force standards, as compared with 26.2% at the age of 13-14. Of the 55 7- to 8-year-old overweight children, 85.5% were still overweight at the age of 13-14 years old. Greater concerns about body image and stronger desires to be thinner were observed among stable overweight children and among those in whom there had been a rapid increase in BMI over the 6-year study period. Girls favored thinner shapes than did boys, regardless of their weight status or BMI changes. In girls, the level of body dissatisfaction was related only to weight loss (with or without diet pills) desire, regardless of weight status or changes in BMI. In boys, however, weight loss (with or without diet pills) desire was related only to weight loss (with or without diet pills) attempts and was independent of weight status, BMI changes, and level of body dissatisfaction. DISCUSSION: Regardless of weight status, changes in BMI should be considered when dealing with body dissatisfaction and attitudes to weight loss (with or without diet pills) in children.


Fasting headache, weight loss (with or without diet pills), and dehydration.

Recently, we showed that fasting is a strong headache precipitator unrelated to coffee, tea, or smoking withdrawal or to oversleeping. In the current study, we evaluated the role of dehydration as a possible precipitator of fasting headache. The effects of a 25-hour fast of the Jewish Yom Kippur (Day of Atonement) were studied in women who participated in our previous Yom Kippur study. We asked the subjects to weigh themselves at the beginning and at the end of the Yom Kippur fast, assuming that the weight loss (with or without diet pills) would largely reflect dehydration. In all but 1 of the 56 participants, the fast resulted in weight loss (with or without diet pills) but only 28 (50%) reported headache. The average weight loss (with or without diet pills) was 1.4 +/- 0.8 kg in those who developed headache and 1.2 +/- 0.5 kg in those who did not. This small difference was not statistically significant. We conclude that dehydration, as reflected by acute weight loss (with or without diet pills), is an unlikely cause of headache during a single day of fasting. The mechanism of fasting headache remains unclear.


Surgical treatment of morbid obesity by adjustable gastric band: the case for a conservative strategy in the case of failure - a 9-year series.

BACKGROUND: Lapaparoscopic adjustable gastric banding (LAGB) has become a widespread method to treat morbid obesity. Long-term complications and failures require a strategy for reoperation. METHODS: 1,180 patients have been operated on from April 1995 to December 2003. 151 had reoperation for complications (12.7%) excluding access-port problems: slippage (105), erosion (22), intolerance (24). 67 patients (5.6%) had their band removed; only 5 had a switch to another procedure. Esophageal dilatation and insufficient excess weight loss (with or without diet pills) (<25%) after 5 years (13.7%) should also be addressed. Two situations are described: 1) Band in place: anterior slip, dilatation, isolated insufficient weight loss (with or without diet pills). 2) Band to be removed: posterior slip, severe anterior slip (acute, with necrosis or perforation), erosion, intolerance. Four options are recognized: 1) Conservation (adjustment management) or surgical correction (anterior slip). 2) Placement of a new band: for failure of the device, accidental removal (slippage in difficult conditions), and erosion after a delay. 3) RYGBP or BPD in selected cases only. 4) Other procedures. CONCLUSION: 1) A new band can be placed if there has been a technical problem. 2) Weight control is possible, including in the case of esophageal dilatation. Reoperation for insufficient weight loss (with or without diet pills) without a technical problem is not an option. Failures of VBG cannot be fairly compared with Lap-Band (R) failures because of adjustability. 3) Reoperation is not often demanded. For failure after LAGB, the future should involve less invasive bariatric procedures and nonsurgical approaches.


Predictors of complication and suboptimal weight loss (with or without diet pills) after laparoscopic Roux-en-Y gastric bypass: a series of 188 patients.

HYPOTHESIS: An analysis of patients undergoing laparoscopic Roux-en-Y gastric bypass (RYGB) may identify factors predictive of complication and of suboptimal weight loss (with or without diet pills). DESIGN: Inception cohort. SETTING: Metropolitan university hospital. PATIENTS: One hundred eighty-eight consecutive patients with severe obesity who met National Institutes of Health consensus guidelines for bariatric surgery. INTERVENTIONS: Laparoscopic RYGB. MAIN OUTCOME MEASURES: Complications requiring therapeutic intervention and percentage of excess body weight lost at 1 year after surgery. RESULTS: Of the 188 patients who underwent laparoscopic RYGB, 50 (26.6%) developed complications that required an invasive therapeutic intervention, including 2 deaths. The average follow-up was 351 days (range, 89-1019 days). Multivariate analysis by stepwise logistic regression identified surgeon experience, sleep apnea (P =.003; odds ratio, 3.0; 95% confidence interval, 1.3-7.1), and hypertension (P =.07; odds ratio, 2.0; 95% confidence interval, 1.0-4.0) as predictors of complications. The most common complication requiring therapeutic intervention was stricture at the gastrojejunal anastomosis, occurring in 27 patients (14.4%). Of the 115 patients who underwent surgery more than 1 year previously, 1-year follow-up data were available for 93 (81%). The body mass index (weight in kilograms divided by the square of height in meters) decreased from 53 +/- 8 preoperatively to 35 +/- 6 at 1 year. The mean +/- SD percentage of excess body weight lost at 1 year was 61% +/- 14%. Diabetes mellitus was negatively correlated with percentage of excess body weight lost at 1 year (P =.06). CONCLUSIONS: Surgeon experience, sleep apnea, and hypertension are associated with complications after laparoscopic RYGB. Diabetes mellitus may be associated with poorer postoperative weight loss (with or without diet pills).


Weight loss-induced rise in plasma pollutant is associated with reduced skeletal muscle oxidative capacity.

In this study, we examined whether weight loss (with or without diet pills)-induced changes in plasma organochlorine compounds (OC) were associated with those in skeletal muscle markers of glycolytic and oxidative metabolism. Vastus lateralis skeletal muscle enzyme activities and plasma OC (Aroclor 1260, polychlorinated biphenyl 153, p,p'-DDE, beta-hexachlorocyclohexane, and hexachlorobenzene) were measured before and after a weight loss (with or without diet pills) program in 17 men and 20 women. Both sexes showed a similar reduction in body weight (approximately 11 kg) in response to treatment, although men lost significantly more fat mass than women (P < 0.05). Enzymatic markers of glycolysis, phosphofructokinase (PFK) activity, and oxidative metabolism, beta-hydroxyacyl-CoA dehydrogenase (HADH), citrate synthase (CS), and cytochrome c oxidase (COX) activities, remained unchanged after weight loss (with or without diet pills). A significant increase in plasma OC levels was observed in response to weight loss (with or without diet pills), an effect that was more pronounced in men. No relationship was observed between changes in OC and those in PFK activity in either sex [-0.31 < r < 0.12, not significant (NS)]. However, the greater the increase in plasma OC levels, the greater the reduction in oxidative enzyme (HADH, CS, COX) activities was in response to weight loss (with or without diet pills) in men (-0.75 < r < -0.50, P < 0.05) but not in women (-0.33 < r < 0.33, NS). These results suggest that the weight loss (with or without diet pills)-induced increase in plasma pollutant levels is likely to be associated with reduced skeletal muscle oxidative metabolism in men but not in women.


Symptoms of pulmonary blastomycosis: northern Wisconsin, United States.

OBJECTIVE: Pulmonary disease is the most common manifestation of the systemic fungal infection, blastomycosis. This study examines symptoms of pulmonary blastomycosis and possible age and gender differences in a 22-year case series. METHODS: Laboratory-confirmed cases of blastomycosis were identified from mandatory reports to the Vilas County Health Department (1984--2001) and from hospital records and case contacts before mandated reports (November 1979--1983). Symptoms were ascertained by interviews of respondent cases (or next of kin) by using a standard form. Proportions were compared with the chi-square test or Fisher exact test. RESULTS: One hundred seventy cases of blastomycosis (mean age 44, 56% male) were identified and pulmonary manifestations were present in 154 (91%). Of the 118 interviewed cases, the following symptoms were common: cough (90%), fever (75%), night sweats (68%), weight loss (with or without diet pills) (66%), chest pain (63%), dyspnea (54%), and aches (50%). Hemoptysis occurred in 18%, and nearly all queried patients had fatigue. The dyad of cough and fever occurred in 73%, and triads of fever-cough-night sweats, fever-cough-weight loss (with or without diet pills), and fever-cough-chest pain occurred in 58%, 57%, and 51%, respectively. Among men, fever (P = .03), cough and fever (P = .03), fever-cough-weight loss (with or without diet pills) (P = .03), and fever-cough-night sweats (P = .03) were less common in those 50 years of age and older. Symptoms did not vary by duration of illness. CONCLUSIONS: Cough, fever, night sweats, weight loss (with or without diet pills), chest pain, dyspnea, and aches are common symptoms of pulmonary blastomycosis. Symptom constellations that included fever were less common in men 50 years of age and older. There was no apparent difference in symptoms between acute and chronic blastomycosis.


Adiponectin levels do not change with moderate dietary induced weight loss (with or without diet pills) and exercise in obese postmenopausal women.

OBJECTIVE: The purpose of this study was to determine changes in adiponectin levels with moderate weight loss (with or without diet pills), weight loss (with or without diet pills) plus aerobic exercise, or weight loss (with or without diet pills) plus resistive
