Surgery for morbid obesity.

BACKGROUND: Obesity is associated with increased morbidity and mortality. Surgery for morbid obesity is considered when other treatments have failed. A number of procedures are available, but the effects of these surgical procedures compared with medical management and with each other are uncertain. OBJECTIVES: To assess the effects of surgery for morbid obesity. SEARCH STRATEGY: Studies were obtained from computerized searches of multiple electronic bibliographic databases, supplemented with hand searches of selected journals and consultation with experts in obesity research. Date of the most recent searches: December 2004. SELECTION CRITERIA: Randomised controlled trials comparing different surgical procedures, and randomised controlled trials and prospective cohort studies comparing surgery with non-surgical management for morbid obesity. DATA COLLECTION AND ANALYSIS: Data were extracted by one reviewer and checked independently by two reviewers. Two reviewers independently assessed trial quality. MAIN RESULTS: Twenty-six trials were included. Two randomised controlled trials and three prospective cohort studies compared surgery with non-surgical management, and 21 randomised controlled trials compared different surgical procedures. The quality of most of the trials was poor; just three trials had adequate allocation concealment. A meta-analysis was not possible due to differences in the surgical procedures performed, measures of weight change and length of follow-up. Compared with conventional management, surgery resulted in greater weight loss (21 kg weight loss at eight years versus weight gain), with improvements in quality of life and comorbidities. Some complications of surgery occurred, such as wound infection. Gastric bypass was associated with greater weight loss, better quality of life and fewer revisions, reoperations and/or conversions than gastroplasty, but had more side-effects. Greater weight loss and fewer side-effects and reoperations occurred with adjustable gastric banding than vertical banded gastroplasty, but laparoscopic vertical banded gastroplasty produced more patients with an excellent or good result and fewer late complications than laparoscopic adjustable silicone gastric banding. Vertical banded gastroplasty was associated with greater weight loss but more vomiting than horizontal gastroplasty. Some postoperative deaths occurred in the studies. Weight loss was similar between open and laparoscopic procedures. Fewer serious complications occurred with laparoscopic surgery, although conversion to open surgery was sometimes required. Most studies found that laparoscopic surgery had a longer operative time. But, it resulted in reduced blood loss and quicker recovery. AUTHORS' CONCLUSIONS: The limited evidence suggests that surgery is more effective than conventional management for weight loss in morbid obesity. The comparative safety and effectiveness of different surgical procedures is unclear.

Morbidity and mortality after hepatic resection of metastases from colorectal cancer.

A review was carried out of morbidity and mortality after hepatic resection for metastatic colorectal cancer in 208 consecutive patients who underwent this procedure between 1980 and 1992. Overall postoperative morbidity and mortality rates were 35 and 2.4 per cent respectively. The major morbidity rate was 18 per cent, the main complications being intra-abdominal sepsis, biliary fistula and haemorrhage. Of the different factors examined, morbidity was significantly related to the extent of liver resection (53 versus 21 per cent after major and minor resections respectively), amount of blood transfused (18 versus 52 per cent for no transfusion and more than 300 ml transfused respectively) and the date of the operation (53 versus 24 per cent before and after 1986 respectively). Multivariate analysis showed that only the extent of hepatic resection and the period at which surgery was performed retained their statistical significance. These data support the opinion that surgical treatment of hepatic metastases from colorectal cancer is an effective procedure with acceptable mortality and morbidity rates. An extensive experience of hepatic surgery is, however, necessary to optimize results.

Long-term morbidity of patients with early breast cancer after sentinel lymph node biopsy compared to axillary lymph node dissection.

BACKGROUND AND OBJECTIVES: Sentinel lymph node biopsy (SLNB) is widely accepted as an excellent method in the management of early breast cancer in patients with clinically negative axillary lymph nodes. Since SLNB requires less traumatic surgery to the axilla than axillary lymph node dissection (ALND), it was assumed to result in reduced shoulder/arm morbidity. However, data on long-term morbidity after SNLB are sparse. The present study was set up to compare long-term arm/shoulder morbidity as well as oncological outcome after SLNB versus ALND in patients with early breast cancer. METHODS: Oncological outcome, objective shoulder/arm morbidity, and subjective complaints after SLNB or ALND for T1 breast cancer were assessed after a minimum follow-up of 20 months. RESULTS: One hundred thirty four patients were included in the study. Thirty-one patients underwent SNLB only, 103 patients had SLNB followed by ALND or ALND only. Loss of strength and hypaesthesia were less frequent after SLNB. No lymph oedema occurred after SNLB without adjuvant radiotherapy. Subjective complaints concerning pain, hypaesthesia, and paresthesia were more common in the ALND group. No axillary recurrence developed in either group. CONCLUSIONS: Isolated SLNB in node-negative pT1 breast cancer patients is a highly efficient tool to reduce postoperative long-term morbidity without compromising the local control of the disease. The reported ameliorations should favour SLNB as staging and treatment modality in patients suffering from early breast cancer.

Acute cellular rejection after liver transplantation: variability, morbidity, and mortality.

Acute cellular rejection of the allograft is a potentially serious complication after liver transplantation, yet its true incidence is unknown. We therefore investigated the frequency of acute cellular rejection reported by transplant centers and its impact on morbidity and mortality. Morbidity was defined as duration of hospitalization. Of 200 articles screened, 18 were selected for inclusion in the study database, in which there was a total of 1,437 patients who received transplants. All contained more than 20 patients and invariably used histopathology for diagnosis of acute cellular rejection. These reports included all transplant patients within a fixed period and sufficient data to determine the incidence of acute cellular rejection. Morbidity data were obtained from our previous series. The mean incidence of acute cellular rejection in all centers was 49.8% (range between centers, 24% to 80%). Two immunosuppressive cohorts were identified: high-dose cyclosporine induction (> or = 5 mg/kg/d) and low-dose cyclosporine induction (< or = 4 mg/kg/d). Acute cellular rejection was reported in 27.0% of the high-dose group and 63.6% of the low-dose group, P = .0001. Strict adherence to Snover's histological criteria for acute cellular rejection did not alter the reported mean incidence. Frequency of acute cellular rejection was 45.2% (range between centers, 24% to 80%) in 8 studies that used Snover's criteria, and 51.6% (range between centers, 37% to 80%) in 10 studies that did not. There was no correlation between mortality and incidence of acute cellular rejection in the 9 studies that reported survival (R2 = .105). Morbidity data showed that the average length of initial hospitalization after transplantation for patients with acute cellular rejection was 52.4 +/- 8.3 (range, 14 to 124) days, in contrast to 28.3 +/- 2.3 (range, 9 to 87) days for patients with no rejection. P = .0008. The total number of hospital days in the first 6 months for patients with acute cellular rejection was 55.6 +/- 8.6 (range, 14 to 124) days and with no rejection, was 37.7 +/- 3.1 (range, 9 to 99) days. P = .0232. The incidence of acute cellular rejection varies widely among transplant centers, regardless of the use of Snover's criteria. Acute cellular rejection appeared to be less frequent in programs using high-dose cyclosporine induction regimens. The presence of acute cellular rejection seemed to have no correlation with mortality but significantly increased morbidity and therefore the cost of transplantation.

Morbid obesity and the transition from welfare to work.

This paper utilizes a rich longitudinal data set--the Women's Employment Study (WES)--to investigate whether obesity, which is common among women of low socioeconomic status, is a barrier to employment and earnings for current and former welfare recipients. We find that former welfare recipients who are both White and morbidly obese have been less successful in transitioning from welfare to work. These women are less likely to work at any survey wave, spend a greater percentage of months between waves receiving cash welfare, and have lower monthly earnings at each wave. The magnitude of the difference in labor market outcomes between the morbidly obese and those who are less heavy is in some cases similar in magnitude to the differences in these labor market outcomes between high school dropouts and graduates. In contrast, we find no such labor market differences associated with morbid obesity for African-American respondents. This paper documents the relationship between weight and labor market outcomes for the first time among the welfare population. In addition, it investigates whether the correlation for White females is due to unobserved heterogeneity. We find that after controlling for individual fixed effects, the point estimate of the correlation of morbid obesity and each of the labor market outcomes falls considerably and is no longer statistically significant. These results are consistent with unobserved heterogeneity causing the correlation between morbid obesity and labor market outcomes. Findings are similar after controlling for the respondent's mental and physical health.

Patients' and doctors' perception of long-term morbidity in patients with testicular cancer clinical stage I. A descriptive pilot study.

Patient-based questionnaires were designed with the aim to identify and rank long-term somatic and psychosocial morbidity in patients with low-stage testicular cancer. A further intention was to compare patients' assessments with experienced doctors' general opinion on quality of life items in cured testicular cancer patients. In pilot study I, 103 tumour-free patients ranked items of physical and psychosocial morbidity after having had various kinds of treatment. Though the ranking procedure appeared to cause some difficulties amongst the patients and subsequently was abandoned, the results indicated considerable differences between the patients' and doctors' evaluations. In pilot study II patients were asked to score the different items. The questionnaire of pilot study II was completed by 107 patients from the Norwegian Radium Hospital (NRH) and 99 relapse-free patients from the Royal Marsden Hospital (RMH) with testicular cancer stage I at least 1 year after infradiaphragmatic radiotherapy (n = 94) or adjuvant chemotherapy (2 cycles, n = 26), or patients who had been followed on the surveillance program (n = 86). A total of 93 doctors completed a similar questionnaire, thereby expressing their general opinion on long-term morbidity in comparable testicular cancer patients as seen during routine clinical follow-up. Both the irradiated patients and those on the surveillance program reported slight degrees of Raynaud-like phenomena, neurotoxicity and ototoxicity, most probably representing "background morbidity" in an age-matched general male population. Doctors tended to underestimate their patients' somatic morbidity, but often overestimated the degree of psychological distress, in particular in patients on the surveillance program. Significant differences between RMH and NRH patients with regard to sexual problems and to leisure time activity may be explained by cultural differences in the two countries. The items presented in the questionnaire used identify important issues for patients cured of testicular cancer which may be used in future multicentre trans-cultural studies assessing these patients' quality of life. This will provide sufficient data for psychometric testing and, together with the findings from patients' free comments, support the final design of a testicular cancer quality of life module.

SPECT myocardial perfusion imaging in morbidly obese patients: image quality, hemodynamic response to pharmacologic stress, and diagnostic and prognostic value.

BACKGROUND: Obesity is a growing epidemic in the United States, and little is known about the characteristics of the morbidly obese population (body mass index [BMI] > or = 40 kg/m2) undergoing stress myocardial perfusion imaging (MPI). METHODS AND RESULTS: We retrospectively reviewed all consecutive morbidly obese patients without known coronary artery disease presenting for a clinically indicated technetium 99m (Tc-99m) gated stress single photon emission computed tomography imaging study over a 42-month period. Studies were analyzed for image quality, for the contribution of attenuation correction to image interpretation, and for the hemodynamic response to pharmacologic stress. In patients who subsequently had cardiac catheterization, the results were compared with those from the initial MPI study, and the Social Security Death Index and hospital medical records were searched to the assess survival rate in the entire cohort. A total of 433 patients were identified with a mean BMI of 47.3 +/- 8 kg/m2 and a mean Tc-99m stress dose of 35.6 +/- 5.4 mCi. Image quality was good in 61% of the patients, adequate in 37%, and poor in 2%. It was found to be dependent on the stressor used (better with exercise) but did not correlate with increasing weight or BMI. Attenuation correction was used in 95% of the studies reviewed and was helpful for image interpretation in 60%. The heart rate response to dipyridamole and adenosine was more pronounced and the blood pressure response to dipyridamole was less pronounced in morbidly obese patients compared with nonobese control patients. In the 43 patients who underwent catheterization, stress MPI had a sensitivity of 95% and negative predictive value of 80%. Kaplan-Meier survival analysis at 1 year showed a significant difference in survival rate of 98.3% for normal MPI studies and 94.0% for abnormal MPI studies (P = .02). CONCLUSION: Diagnostic-quality single photon emission computed tomography imaging is feasible in the majority (98%) of morbidly obese patients with the use of a dual-head camera, attenuation correction, and high stress Tc-99m tracer doses. Exercise stress was associated with better image quality. The prognostic value of a normal MPI study in this population appears to be less favorable than in non-morbidly obese patients.

Early morbidity after radiotherapy with or without chemotherapy in advanced head and neck cancer. Experience from four nonrandomized studies.

BACKGROUND: Data on early treatment-related morbidity after radiotherapy alone (RT; 217 patients) or combined with chemotherapy (RT + CT; 182 patients) of head and neck squamous cell carcinoma are analyzed. PATIENTS AND METHODS: The patients were treated between November 1985 and November 1996 in four Swiss centers that independently introduced combined-modality therapy in selected cases of head and neck cancer. RT schedules varied among the four centers, but within each institution all patients received the same dose-fractionation schedule irrespective of whether they had CT or not. The following early morbidity items were evaluated: skin, mucosa, larynx, salivary glands, dysphagia, weight loss, and toxic death. Toxicity was scored using the EORTC/RTOG scale. RESULTS: Although considerable variation was noted among the treatment schedules/centers, the main findings are as follows: (1) early morbidity was significantly enhanced after all five RT + CT schedules compared with RT alone; (2) typically, a third of the patients lost > 10% of their body weight during concurrent RT + CT as compared with 10% of the patients receiving RT alone; (3) at 12 weeks, the prevalence of grade 2 morbidity was 25-60% after RT + CT as compared with 4-20% after RT alone. CONCLUSION: A number of early morbidity items were found to be more prevalent and/or more severe after RT + CT than after RT alone.

Hypoadiponectinaemia and high risk of type 2 diabetes are associated with adiponectin-encoding (ACDC) gene promoter variants in morbid obesity: evidence for a role of ACDC in diabesity.

AIMS/HYPOTHESIS: Morbid obesity (BMI>40 kg/m(2)) affecting 0.5-5% of the adult population worldwide is a major risk factor for type 2 diabetes. We aimed to elucidate the genetic bases of diabetes associated with obesity (diabesity), and to analyse the impact of corpulence on the effects of diabetes susceptibility genes. METHODS: We genotyped known single nucleotide polymorphisms (SNPs) in the adiponectin-encoding adipocyte C1q and collagen-domain-containing (ACDC) gene (-11,391G>A, -11,377C>G, +45T>G and +276G>T), the peroxisome proliferator-activated receptor gamma (PPARG) Pro12Ala SNP and ACDC exon 3 variants in 703 French morbidly obese subjects (BMI 47.6+/-7.4 kg/m(2)), 808 non-obese subjects (BMI<30 kg/m(2)) and 493 obese subjects (30< or =BMI<40 kg/m(2)). RESULTS: Two 5'-ACDC SNPs -11,391G>A, -11,377C>G were associated with adiponectin levels (p=0.0003, p=0.008) and defined a "low-level" haplotype associated with decreased adiponectin levels (p=0.0002) and insulin sensitivity (p=0.01) and with a risk of type 2 diabetes that was twice as high (p=0.002). In contrast, the prevalence of the PPARG Pro12Ala was identical in diabetic and normoglycaemic morbidly obese subjects. The PPARG Pro12 allele only displayed a trend of association with type 2 diabetes in the non-obese group. ACDC exon 3 variants were associated with type 2 diabetes in the non-obese group only (odds ratio 7.85, p<0.0001). In contrast, the 5'-ACDC "low-level" haplotype was associated with type 2 diabetes in obese and morbidly obese subjects (odds ratio 1.73 and 1.92) but not in non-obese individuals. CONCLUSIONS/INTERPRETATION: These data clarify the contribution of the 5'-ACDC SNPs to the risk of diabesity. Their interaction with corpulence suggests for the first time a different genetic profile of type 2 diabetes in morbidly obese patients compared with in less obese individuals.

Morbidities in patients with hypoplastic left heart syndrome.

We sought to document morbidities and growth for patients with hypoplastic left heart syndrome (HLHS) to inform the initial surgical decision and understand healthcare needs. Data were obtained on 137 patients with HLHS, born between 1989 and 1994, who survived staged surgery ( n = 62) or transplantation ( n = 75) and had follow-up information available from four pediatric cardiac surgical centers. In patients with HLHS older than 1 year of age at follow-up, 93% experienced at least one major postsurgical morbidity. Morbidities depended on the surgery received. Hypertension, renal compromise, and abnormal infections were more common in transplanted patients than staged surgery patients. Staged surgery patients used more anticongestive medications and experienced more morbidities requiring interventional catheterization than did transplanted patients. Rejection was common for transplanted patients. On average these children spent 23 days per year in the hospital. Patients with HLHS were small for their age; 43% of staged surgery patients weighed below the third percentile at last information, compared to 19% of transplanted patients ( p = 0.003). The median height percentile was the 10th in both groups. Normal activity level was reported in more transplanted patients (90%) than staged surgery patients (49%; p < 0.001). Trade-offs between mortality and morbidity outcomes can help inform the initial surgical decision.

Labor analgesia for the morbidly obese parturient: an old problem--new solution.

INTRODUCTION: Morbid obesity is perhaps the most common nutritional disorder seen in pregnancy, and morbidly obese parturients have more pregnancy complication than normal body mass index (BMI) pregnant patients. Combined spinal epidural anesthesia (CSEA) has become a well-established alternative to epidural analgesia for labor pain in many institutions. However, due to lack of an appropriately long needle design, its advantages have not been routinely available to laboring morbidly obese patients. CASE REPORT: I herein, present a case of a morbidly obese parturient whose labor analgesia was managed with CSEA administered with the newly released, commercially available, CSEA needle set, specifically designed for morbidly obese patients.

Modeling of air pollution and its relationship with mortality and morbidity in Madrid, Spain.

OBJECTIVE: Evaluation of the association between air pollution and mortality and morbidity is becoming ever more complex owing to changes in inner-city air pollution, marked by decreasing values for all main pollutants save those associated with traffic. This has led to the need for the study of new epidemiological scenarios in which most pollutants are below guideline values. Nonetheless, the health effects are significant. METHODS: This report presents the results of a statistically based model for real-time forecasting of mortality and morbidity in Madrid, with meteorological and pollution series serving as inputs. RESULTS AND CONCLUSIONS: Not only did the models perform well with correlation coefficients between predicted and observed values (r = 0.683 for mortality, r = 0.681 for morbidity), but they enabled quantification of the impact of air pollution on mortality and morbidity (with increases ranging from 1. 8% to 12% for mortality and from 2.3% to 18% for morbidity for a 25-microg/m(3) increase in pollutants). Moreover, attention should be drawn to the observation that the model proved to be easy to implement and operate on a routine basis.

Laparoscopic vertical banded gastroplasty for morbid obesity. Assessment of efficacy.

BACKGROUND: The advantages of treating morbidly obese patients via the laparoscopic approach have been demonstrated, in particular, for adjustable silicone gastric banding, but this operation is associated with a high rate of late complications. Gastric bypass and malabsorbitive procedures are feasible via the laparoscopic approach, but they entail a prolonged operating time and a consistently high morbidity rate. Laparoscopic vertical banded gastroplasty represents an effective alternative. METHODS: We performed 250 consecutive LVBG between November 1995 and February 2000. The procedure consisted of a personal technique designed to reproduce, by laparoscopy, MacLean's modification of the standard open Mason vertical-banded gastroplasty, with a calibrated transgastric window, a complete division between the staple lines, and a 5-cm-circumference polypropylene collar. RESULTS: The operative time was 95 min and the conversion rate was 0.8%. Operative mortality was nil; early and late complications, respectively, were 4.4% and 4%; the reoperation rate was 2%. Global results at 4 years were as follows: excess weight loss (EWL) 61%, success rate (excess weight <50%) 76.9%, body mass index (BMI) 29.4 kg/m2. In morbidly obese patients, the EWL at 4 years was 62.2%, with a 77.4% success rate and a 28.4 kg/m2 BMI; in superobese patients, the EWL at 4 years was 54.9% with a 50% success rate and a 35.5 kg/m2 BMI. The overall follow-up rate was 92%. CONCLUSIONS: LVBG is an effective and safe operation in morbidly obese patients, providing good weight loss with a low morbidity rate, no mortality, and minimum discomfort. However, in superobese patients, the weight loss results are disappointing; in these patients, LVBG is questionable and more complex procedures should be considered.

Gastrointestinal symptoms are more intense in morbidly obese patients.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass is an effective treatment for morbid obesity. However, little information is available on gastrointestinal (GI) symptomatology in this population. This study compares GI symptoms in morbidly obese patients to that of control subjects. METHODS: A previously validated, 19-point GI symptom questionnaire was administered prospectively to each patient seen for surgical consultation for morbid obesity. The symptoms were then grouped into 6 clusters as follows: (1) abdominal pain, (2) irritable bowel, (3) GERD, (4) reflux, (5) sleep disturbance, (6) dysphagia. The result of each cluster of symptoms expressed as mean +/- standard deviation of obese versus control is compared using student's t-test with significance p = 0.05. RESULTS: Forty-three patients (40 female, 3 male) age 37.3 +/- 8.6 with BMI 47.8 +/- 4.9, and 36 healthy control subjects (23 female, 13 male), age 39.8 +/- 11.2, completed the questionnaire. Results of each cluster for morbid obese vs control subjects are expressed as mean +/- standard deviation: Abdominal pain 25.3 +/- 18.0 vs 12.1 +/- 11.4, p = 0.0002; irritable bowel 23.0 +/- 14.8 vs 15.6 +/- 13.3, p = 0.02; GERD 40.3 +/- 18.9 vs 22.3 +/- 16.1, p = 0.0001; reflux 29.9 +/- 19.0 vs 11.8 +/- 13.4, p = 0.0001; sleep disturbance 50.6 +/- 28.9 vs 32.9 +/- 26.8, p = 0.006; dysphagia 10.9 +/- 15.6 vs 7.2 +/- 10.6, p = NS. CONCLUSIONS: Morbidly obese patients experience more intense GI symptoms than normal subjects, whereas dysphagia is equivalent to normal subjects. These data may be important in counseling patients and understanding that their complaints are legitimate. Follow-up in the postoperative period is needed to determine if these symptoms are improved with an operation.

Sudden death as a result of heart disease in morbid obesity.

Patients with morbid obesity have high rates of sudden, unexpected cardiac death. The mechanism of death in these patients is uncertain. Twenty-eight patients with morbid obesity (22 sudden cardiac deaths, 6 unnatural deaths) were compared to 11 age-matched nonobese patients with traumatic deaths. Heart weight, left ventricular cavity diameter, left and right ventricular wall thickness, ventricular septal thickness, epicardial fat thickness, and extent of coronary artery atherosclerosis were determined; myocyte size, nuclear size, and degree of interstitial fibrosis were calculated morphometrically. Mean heart weights in the patients with morbid obesity were increased but remained constant as a percentage of body weight. Of the gross parameters, only heart weight and left ventricular cavity size were independent predictors of obesity. Of microscopic parameters, only nuclear area was an independent predictor of obesity. Of 22 patients with morbid obesity, dilated cardiomyopathy was the most frequent cause of sudden cardiac death in (10 patients), followed by severe coronary atherosclerosis (6), concentric left ventricular hypertrophy without left ventricular dilatation (4), pulmonary embolism (1), and hypoplastic coronary arteries (1). The cardiomyopathy of morbid obesity is characterized by cardiomegaly, left ventricular dilatation, and myocyte hypertrophy in the absence of interstitial fibrosis. It is the most common cause of sudden cardiac death in these patients.

Neonatal morbidity after preterm delivery in the presence of documented lung maturity.

OBJECTIVE: Our purpose was to determine the incidence of significant neonatal morbidity in fetuses with documented pulmonary maturity delivered before 37 weeks' gestation. STUDY DESIGN: A retrospective review of 213 pregnancies with documented fetal lung maturity (lecithin/sphingomyelin ratio > or = 2.0 or phosphatidylglycerol present) and delivery before 37 weeks was performed. The incidence of neonatal respiratory distress syndrome, bronchopulmonary dysplasia, grade 3 or 4 intraventricular hemorrhage, necrotizing enterocolitis, patent ductus arteriosus, retinopathy of prematurity, infectious morbidity, hyperbilirubinemia, and admission to the special care nursery was determined for those pregnancies with intact membranes and preterm premature rupture of membranes. RESULTS: Serious neonatal morbidity declined with advancing gestational age and was less common after 32 completed weeks of pregnancy. Although the frequencies of respiratory distress syndrome, grade 3 or 4 intraventricular hemorrhage, and necrotizing enterocolitis were 19.4% (12/62), 8.1% (5/62), and 4.8% (3/62), respectively, at < or = 33 weeks' gestation, one case of respiratory distress syndrome, one case of grade 3 intraventricular hemorrhage, and one case of necrotizing enterocolitis occurred in the 151 neonates born at > or = 34 weeks' gestation. CONCLUSIONS: In spite of fetal lung maturity major neonatal morbidity was observed in our patient population. These data relating neonatal morbidity to gestational age are useful in the critical decision regarding timing of delivery.

Impact of gastric restrictive surgery on hypertension in the morbidly obese.

Hypertension is a major health risk factor in patients who are morbidly obese. Two hundred eighty-nine morbidly obese patients undergoing gastric restrictive surgery were evaluated for the presence of hypertension (blood pressure greater than or equal to 160/90 mm Hg or currently undergoing antihypertensive therapy) pre- and postoperatively. Of 74 (26%) preoperatively hypertensive patients, 67 (91%) were available for follow-up. Preoperative hypertension resolved in 66% (44 of 67) of patients following gastric restrictive surgery. Superobese and morbidly obese patients had similar reductions in hypertension after surgery (69% versus 63%). Patients not receiving antihypertensives preoperatively had a greater reduction of hypertension than those medically treated preoperatively (78% versus 58%). The amount of weight loss significantly predicted the reduction of hypertension, whereas follow-up weight achieved did not. The amounts of weight loss for patients with resolved and persistent hypertension were 89.3 +/- 5.6 lbs (mean +/- standard error of the mean +ADSEM+BD) and 66.0 +/- 8.3 lbs, respectively (p less than 0.02). For patients with resolved hypertension, follow-up weights for the morbidly obese and superobese were 162.0 +/- 10.8 lbs (133% +/- 4% ideal body weight +ADIBW+BD) and 220.4 +/- 9.5 lbs (170% +/- 7% IBW). Gastric restrictive surgery is effective therapy for hypertension in morbidly obese patients. Patients need not achieve weights approaching IBW to enjoy the benefits of gastric restrictive surgery on hypertension.

Morbidity in Swedish farmers, 1978-1983, according to national hospital records.

A number of epidemiological studies have shown that farmers have low mortality rates. To examine morbidity risks for male and female farmers in Sweden, the national hospital care registry was updated with information on occupation derived from the census of 1980. The cause-specific morbidity of farmers was compared with the morbidity of all economically active individuals in the same areas. A total of 60,515 farmers and 2,843,217 controls have been studied. The morbidity rates of the farmers were generally low. Male farmers had a significantly lower risk for cancer diseases, mental diseases, cardiovascular diseases, diseases of the digestive system, the uro-genital system, and skin diseases. Female farmers had a lower risk for diseases of the respiratory system, uro-genital system, skin diseases, diseases of the locomotor system, and accidents. A notable discrepancy between males and females concerning cardiovascular diseases was observed Male farmers had a significantly lower risk than other men while female farmers had the same risk level as other economically active women. The relative risk of hospitalization for mental disease was also low. Male farmers had a risk for alcohol-dependent diseases and attempted suicides which was less than one-third of the risk for all economically active men. Concerning work-environment-related diseases in farming, it was shown that young male farmers had low rate ratios. However, the risks were found to increase with every decade, indicating that occupational health risks contribute to morbidity with advancing age.
