Physical and psychosocial outcome in morbidly obese patients with and without bariatric surgery: a 4 1/2-year follow-up.

BACKGROUND: Morbidly obese patients show high somatic and psychiatric co-morbidity. Bariatric surgery is accepted as the obesity treatment with the greatest long-term success. There is growing evidence that follow-up studies should address somatic as well as psychosocial conditions of patients undergoing bariatric surgery and non-operatively treated patients. This study investigates the physical and psychosocial outcomes of patients with and without bariatric surgery. METHODS: A sample of 131 morbidly obese patients applying for bariatric surgery underwent somatic and psychological assessment (T0). A first follow-up study (T1) was conducted 2 years after T0 in 119 patients. The present second follow-up (T2) was carried out 4 1/2 years after T0 and 3.2 years after potential bariatric surgery. Psychological/psychosocial measures were collected in the 93 patients, 63 of whom were treated surgically, via the Psychosocial Stress and Symptom Questionnaire (PSSQ) and a telephone interview covering BMI, employability, medication, doctor consultations, eating behavior, and physical/psychological well-being. RESULTS: Patients with and without bariatric surgery showed a BMI reduction, which was significantly greater in those who underwent surgery (P<.001). The average percentage of excess weight loss (%EWL) between T0 and T2 was 11.5% in patients with no bariatric surgery, 36.0% in patients with laparoscopic gastric banding, and 52.8% in patients with laparoscopic gastric bypass (%EWL between T0 and T2 in patients of all groups significant, P<.001). Patients with and without surgical treatment showed significant improvement with regard to depressive symptoms and binge-eating behavior. Three-quarters of the surgically-treated and two-thirds of the non-treated patients rated their physical, psychological, and psychosocial well-being as "good" at T2. CONCLUSION: After 3 to 4 years, all of the patients have adapted well to their weight and body appearance, regardless of whether they have undergone surgery. Weight loss is, however, greater for operated patients, which strongly decreases the risk of developing obesity-related co-morbidities.

Health-related quality of life in morbid obesity.

BACKGROUND: In order to evaluate the impact of severe obesity and its treatment on quality of life (QoL), it would be important to first identify the areas of QoL most likely to be affected by the disease. METHODS: We first constructed a list of 187 items potentially related to QoL of patients with morbid obesity. From this list, consecutive candidates for bariatric surgery were asked to identify what they felt were the most significant items and to grade their importance. The item impact was determined from the proportion of patients who identified it as important, and the mean importance score attributed to this item (impact score = frequency X importance). RESULTS: 100 patients (68 female; mean body mass index 51.5 kg/m(2); mean age 42) were interviewed. Overall, the impact of morbid obesity was more important in women than in men. The areas of impairment were very similar in both groups, with the important difference that women ranked their dissatisfaction with physical appearance higher than men. The items having the most important impact on QoL clustered into 7 domains: 1) activity/mobility; 2) symptoms; 3) personal hygiene/clothing; 4) emotions; 5) social interactions; 6) sexual life; and 7) eating behavior. CONCLUSION: The impact of morbid obesity on QoL is not limited to the activity/mobility domain. Morbid obesity contributes to the impairment of all domains of what is usually referred to as "health-related quality of life".

Gallstone formation after weight loss following gastric banding in morbidly obese Dutch patients.

BACKGROUND: Obesity is a risk factor for the development of gallstones. Rapid weight loss may be an even stronger risk factor. We retrospectively assessed the prevalence and risk factors of gallstone formation after adjustable gastric banding (AGB) in a Dutch population. METHODS: All patients who underwent AGB between Jan 1992 and Dec 2000 for morbid obesity were invited to take part in this study. Transabdominal ultrasonography of the gallbladder was performed in those patients without a prior history of cholecystectomy (Group A). Additionally, 45 morbidly obese patients underwent ultrasonography of the gallbladder before weight reduction surgery (Group B). RESULTS: 120 patients were enrolled in the study (Group A). Prior history of cholecystectomy was present in 21 patients: 16 before and 5 after AGB. Ultrasonography was performed in 98 patients: gallstones were present in 26 (26.5%). On multivariate analysis, neither preoperative weight, nor maximum weight loss, nor the interval between operation and the postoperative ultrasonography were determinants of the risk for developing gallstone disease. Prevalence of gallstones was significantly lower in the morbidly obese patients who had not yet undergone weight reduction surgery (Group B). CONCLUSIONS: Rapid weight loss induced by AGB, is an important risk factor for the development of gallstones. No additional determinants were found. Every morbidly obese patient undergoing bariatric surgery must be considered at risk for developing gallstone disease.

Postoperative results after desflurane or sevoflurane combined with remifentanil in morbidly obese patients.

BACKGROUND: This randomized prospective study with blinded postanesthesia care unit (PACU) observers compared the recovery profiles in morbidly obese patients who received sevoflurane or desflurane for maintenance of anesthesia in combination with a remifentanil target controlled infusion (TCI). METHODS: 50 morbidly obese patients scheduled for laparoscopic gastric banding were included to receive BIS-guided sevoflurane or desflurane anesthesia with BIS-triggered inhalation boli in combination with remifentanil TCI. In the PACU, the following recovery scores were investigated: Modified Aldrete score, a modified Observers' Assessment of Alertness/Sedation Scale (OAA/S), pain numerical rating scale (NRS), oxygen saturation (SpO(2)) and postoperative nausea and vomiting (PONV). RESULTS: OAA/S and NRS pain scores showed a similar evolution in both groups from the moment of PACU admission up to 120 minutes after admission. In both groups, patients showed no serious hypoxemia during PACU stay. Incidence of PONV was shorter lasting in the sevoflurane group compared to the desflurane group. CONCLUSIONS: No clinically relevant difference was found in recovery in the PACU between morbidly obese patients anesthetized with desflurane or sevoflurane. Both agents resulted in satisfactory recovery in morbidly obese patients.

Effect of massive weight loss induced by bariatric surgery on serum levels of interleukin-18 and monocyte-chemoattractant-protein-1 in morbid obesity.

BACKGROUND: Morbid obesity is associated with insulin resistance (IR), chronic inflammation and premature atherosclerosis. Since vascular inflammation may contribute to the increased risk of cardiovascular morbidity and mortality of these patients, we studied circulating Interleukin-18 (L-18) and monocyte-chemoattractant-protein-1 (MCP-1) levels in 37 patients with morbid obesity before and after significant weight loss induced by bariatric surgery and their preoperative and postoperative associations with C-reactive protein (CRP) and IR-associated factors. METHODS: High sensitivity assays were used to measure concentrations of fasting CRP, IL-18 and MCP-1. Differences between patients before and after bariatric surgery were analyzed by Student's paired t-test. To investigate the associations of the observed reductions of values, delta of parameters were calculated and preoperative, postoperative and delta data were tested by univariate and multivariate linear regression. RESULTS: After a mean follow-up period of 26.5 months and a massive weight loss of 35 kg induced by bariatric surgery, circulating IL-18 levels decreased by 37% (P<0.001) and circulating MCP-1 levels by 47% (P<0.001). Multiple linear regression of delta values of IL-18 showed that only 2-hour glucose (P=0.008) remained independently and significantly associated with IL-18, whereas multiple linear regression analysis of delta values of MCP-1 revealed that only delta of HOMA-IR (P<0.001) remained independently and significantly associated with MCP-1, respectively. CONCLUSIONS: Because both biomarkers have been shown to play an important role in the development and progression of atherosclerosis, the observations presented in this study could be of clinical relevance for morbidly obese patients undergoing bariatric surgery.

Gastric bypass for morbidly obese patients with established cardiac disease.

BACKGROUND: Bariatric surgery has often been avoided in patients with known cardiac disease because of the risks inherent in this patient population. This study was done to evaluate both the risks and benefits of Roux-en-Y gastric bypass (RYGBP) in morbidly obese patients with established cardiac disease. METHODS: Data were analyzed to compare preoperative with postoperative co-morbid cardiac risk factors, peri-operative and postoperative complications, and change in body mass index (BMI) in 77 consecutive patients who had a preoperative diagnosis of cardiac disease and underwent RYGBP between March 1998 and January 31, 2006. Findings were compared to a concomitant control group without cardiac disease. RESULTS: The preoperative presence of cardiac disease was manifested primarily as coronary artery disease (CAD) (45 patients) or as congestive heart failure (CHF) (32 patients). Of the patients with CAD, 60% had diabetes, 91% had hypertension and 39% had hyperlipidemia. 58% had one or more prior invasive cardiac procedures. In the CHF group, 50% had diabetes, 71% had hypertension and 44% had hyperlipidemia. The average length of stay was 3.7 days for CAD patients and 3.3 days for CHF compared to 3.0 days for controls. All co-morbid conditions were improved, and no patient died from cardiac disease. However, one patient died as a complication of GI bleeding, one patient subsequently underwent revascularization and another underwent stenting. Other complications up to 5 years postoperatively were frequent but seldom life-threatening. CONCLUSION: RYGBP surgery in patients with existing cardiac disease appears to have acceptable risk and is effective in reducing the co-morbid conditions of diabetes, hypertension, hyperlipidemia, sleep apnea and arthritis, but longer term data are needed.

APO A-V-1131T-->C polymorphism frequency and its association with morbidity in a Brazilian elderly population.

Identification of genetic polymorphisms as risk factors for complex diseases affecting older people can be relevant for their prevention, diagnosis and management. The -1131T-->C polymorphism of the apolipoprotein A-V gene (APO A-V) is tightly linked to lipid metabolism and has been associated with increased triglyceride levels and familial dyslipidemia. The aims of this study were to analyze the allele and genotype frequencies of this polymorphism in a Brazilian elderly population and to investigate any association between the polymorphism and major morbidities affecting elderly people. This polymorphism was investigated in 371 individuals, aged 66-97 years, in a Brazilian Elderly Longitudinal Population Study. Major morbidities investigated were: cerebrovascular diseases (CVD); myocardial infarction (MI); type 2 diabetes; hypertension; obesity; dementia; depression; and neoplasia. DNA was isolated and amplified by PCR and its products were digested with restriction enzyme Tru1I. T and C allele frequencies were 0.842 and 0.158, respectively. Our population showed allele frequencies that were similar to European and Afro-American and different from Asiatic populations. Genotype distributions were not within Hardy-Weinberg equilibrium only for the obesity subject sample. On the other hand, a significant association between the C allele and obesity in the presence of CVDxdepression interaction was observed. Logistic analysis showed no association of the polymorphism with each morbidity group. Therefore, the C allele in elderly Brazilian subjects may represent a risk factor for these morbidity interactions, which may lead to better comprehension of their pathophysiology.

The use and limitations of ultrasonography in the diagnosis of liver morbidity attributable to Schistosoma mansoni infection in community-based surveys.

UNLABELLED: The objective of this population-based study was to estimate the liver morbidity attributable to Schistosoma mansoni infection by ultrasonography adopting the proposed standard protocols of the Cairo Meeting on Ultrasonography, 1991. We examined 2384 individuals representing 20% of the households of the rural population of the Ismailia Governorate, East of Delta, Egypt. Prevalence of S. mansoni and S. haematobium infections were 40.3% and 1.7% respectively. Portal tract thickening (PTT) grade 1, 2 and 3 considered diagnostic of schistosomal liver morbidity was detected in 35.1%, 1.3 and 0.2 individuals respectively. Generally, ultrasonographically-detected pathological changes increased with age, but correlated with intensity of infection only in age group 20-59 years. Comparing individuals with and without S. mansoni infections in an endemic and a non-endemic community indicated no significant difference between the former and the latter in either case. IN CONCLUSION: ultrasonography had a limited value in estimating schistosomal liver morbidity in our population-based study where early grades of liver morbidly were prevalent. The criteria of diagnosing grade I portal fibrosis need to be revised as well as the staging system proposed by the Cairo Meeting on ultrasonography in schistosomiasis.

Estimating clinical morbidity due to ischemic heart disease and congestive heart failure: the future rise of heart failure.

OBJECTIVES: Many developed countries have seen declining mortality rates for heart disease, together with an alleged decline in incidence and a seemingly paradoxical increase in health care demands. This paper presents a model for forecasting the plausible evolution of heart disease morbidity. METHODS: The simulation model combines data from different sources. It generates acute coronary event and mortality rates from published data on incidences, recurrences, and lethalities of different heart disease conditions and interventions. Forecasts are based on plausible scenarios for declining incidence and increasing survival. RESULTS: Mortality is postponed more than incidence. Prevalence rates of morbidity will decrease among the young and middle-aged but increase among the elderly. As the milder disease states act as risk factors for the more severe states, effects will culminate in the most severe disease states with a disproportionate increase in older people. CONCLUSIONS: Increasing health care needs in the face of declining mortality rates are no contradiction, but reflect a tradeoff of mortality for morbidity. The aging of the population will accentuate this morbidity increase.

Distinct trends in tuberculosis morbidity among foreign-born and US-born persons in New Jersey, 1986 through 1995.

OBJECTIVES: This study evaluated tuberculosis (TB) morbidity trends among foreign-born and US-born persons. METHODS: TB surveillance data in New Jersey from 1986 to 1995 were analyzed. RESULTS: The overall TB incidence rate in New Jersey declined 15% from 1992 to 1995 after 7 years of increase. However, the incidence rate of TB in foreign-born persons increased 75% from 1986 through 1995. The proportion of foreign-born persons with TB increased from 20% in 1986 to 37% in 1995. CONCLUSIONS: TB morbidity among foreign-born persons has continued to increase, despite the decline in overall TB morbidity since 1992. Targeted TB prevention and control strategies should be developed to effectively reduce TB morbidity in foreign-born persons.

Genetic studies of the sulfonylurea receptor gene locus in NIDDM and in morbid obesity among French Caucasians.

The sulfonylurea receptor (SUR) is a key component in glucose-stimulated insulin secretion. Obesity and NIDDM are frequently associated and share some metabolic abnormalities, suggesting that they might also share some susceptibility genes. Thus, the SUR encoding gene is a plausible candidate for a primary pancreatic beta-cell defect and thus for hyperglycemia and weight gain. Through association and linkage studies, we have investigated the potential role of the SUR gene in families with NIDDM and in two independent sets of morbidly obese families. The exon 22 T-allele at codon 761 was more common in patients with NIDDM (7.7%) and morbid obesity (7.8%) than in control subjects (1.8%, P = 0.030 and P = 0.023, respectively). This variant was associated with morbid obesity (odds ratio 3.71, P = 0.017) and NIDDM (odds ratio 2.20, P = 0.04; association dependent on BMI). Although the frequencies for intron 24 variant were similar in all groups, morbidly obese patients homozygous for the c-allele had a more deleterious form of obesity. Sib-pair linkage studies with NIDDM in French Caucasian families gave no evidence for linkage to the SUR locus. However, in one set of the obese families, we found an indication for linkage with a SUR-linked microsatellite marker (D11S419, P = 0.0032). We conclude that in Caucasians, the SUR locus may contribute to the genetic susceptibility to NIDDM and obesity.

Cardiovascular morbidity and early mortality cluster in parents of type 1 diabetic patients with diabetic nephropathy.

OBJECTIVE: A familial predisposition was proposed to be a determinant of the increased morbidity and mortality from cardiovascular disease in type 1 diabetic patients with diabetic nephropathy. The insertion allele of an insertion/deletion polymorphism in the ACE (ACE/ID) gene seems to protect against coronary heart disease in nondiabetic and diabetic subjects. The aim of the present study was to evaluate these hypotheses in parents of a large group of type 1 diabetic patients with and without diabetic nephropathy. RESEARCH DESIGN AND METHODS: We investigated cardiovascular morbidity and mortality of parents of 163 type 1 diabetic patients with nephropathy and parents of 163 sex- and age-matched normoalbuminuric patients with type 1 diabetes. RESULTS: Kaplan-Meier curves showed that total parental mortality was significantly increased in parents of type 1 diabetic patients with nephropathy (121 of 244 [ approximately 50%] ) as compared with parents of normoalbuminuric type 1 diabetic patients (119 of 269 [approximately 44%]) (P = 0.008 [log-rank test]) partially due to an increase in cardiovascular deaths (48 of 244 [approximately 20%] vs. 42 of 269 [approximately 16%], P<0.05). In addition, more patients with nephropathy, as compared with the normoalbuminuric group, had at least one parent with fatal/nonfatal cardiovascular disease (46% [95% CI 38-54] vs. 36% [28-44], P = 0.05). Fathers of patients homozygous for the I-allele of the ACE/ID polymorphism had significantly less myocardial infarction as compared with other genotypes (P = 0.03), regardless of the nephropathic state of the offspring. CONCLUSIONS: Cardiovascular morbidity and early mortality clusters in parents of type 1 diabetic patients with diabetic nephropathy The ACE/ID polymorphism helps explain the increased morbidity from cardiovascular disease.

Inflammatory bowel disease: a study of the association between anxiety and depression, physical morbidity, and nutritional status.

BACKGROUND: The etiology of inflammatory bowel disease is unclear, and the role played by anxiety and depression is highly controversial. Anxiety and depression in patients with inflammatory bowel disease could be secondary to disabling symptoms, but the interaction between physical morbidity and psychologic illness in these subjects has not been sufficiently investigated. Patients with inflammatory bowel disease are nevertheless frequently undernourished, but there are no studies on the association between anxiety and depression and malnutrition. This study was designed to characterize anxiety and depression in subjects affected by inflammatory bowel disease and to establish the influence of physical morbidity and/or nutritional status on psychologic disorders. METHODS: Seventy-nine consecutive patients, 43 with Crohn's disease (CD) and 36 with ulcerative colitis (UC), were enrolled in the study. An index of the disease activity and physical morbidity was obtained by the simplified Crohn's Disease Activity Index and Truelove-Witts criteria and using the Clinical Rating Scale. Thirty-six healthy volunteers were studied as controls. All the subjects were given the State and Trait Anxiety Inventory (STAI) test and the Zung self-rating Depression Scale. RESULTS: The percentage of subjects with state anxiety was significantly higher in the CD (P < 0.001) and UC (P < 0.001) groups than in control subjects. There was no significant difference in trait anxiety among groups. The percentage of subjects with depression was significantly higher in the CD (P < 0.05) and UC (P < 0.05) groups than in control subjects. State anxiety and depression were significantly associated with physical morbidity and correlated with malnutrition in CD and UC patients. CONCLUSION: Anxiety and depression in patients with inflammatory bowel disease could be reactive to the disabling symptoms and to malnutrition. As measured with the STAI, personality trait of anxiety does not seem to play an important role in inflammatory bowel disease.

Past maternal experience of asthma, childhood morbidity, and the psychosocial impact of the disorder.

Both previous experience of asthma, either in person or in a close family contact, by the mother of an asthmatic child and the child's current morbidity may influence the psychosocial impact of the disorder. A questionnaire concerning prior asthma experience, current psychosocial impact, and morbidity was returned by the mothers of 124 young asthmatic children. Family communication was significantly worse in the past maternal contact group. There were significant trends between morbidity and family communication, emotional distress, and manipulation. No beneficial effect of previous experience of asthma on measures of psychosocial disturbance experienced by the mothers of asthmatic children was detected. Increased psychosocial disturbance was associated with higher morbidity from asthma in the child.

Changing morbidity patterns in children in Dutch general practice: 1987-2001.

OBJECTIVES: To examine the presentation and pattern of childhood morbidity in general practice compared with 14 years ago. METHODS: We used data of all children aged 0-17 years from two cross-sectional surveys performed in 1987 and 2001 in general practice in the Netherlands. The total number of children in the practices participating in these surveys were 86,577 children in 1987 and 82,053 children in 2001. First of all, we compared consultation rates of children in general practice. Secondly, childhood morbidity was assessed by episodes of disease, coded according to the International Classification of Primary Care (ICPC). We compared childhood morbidity in 1987 and 2001 by assessing the distribution of episodes among ICPC chapters stratified by ethnicity, and by comparing incidence rates of most frequently presented diseases. RESULTS: Childhood consultation rates have decreased from 2.7 visits a year per child in 1987 to 2.1 in 2001. The distribution of episodes among ICPC chapters had also changed. Respiratory problems are still the most frequently presented health problem in children but the proportion has decreased from 25.5% in 1987 to 23.3% in 2001. Skin problems were presented more often (23.0% in 2001 versus 17.8 in 1987), and Western children more often presented with skin problems than with respiratory problems in 2001. Incidence rates of most respiratory diseases have decreased and specific skin diseases (dermatomycosis, impetigo and eczema) were diagnosed more often. CONCLUSION: In the Netherlands, childhood morbidity has changed. Skin diseases have become more important in general practice and respiratory problems are declining.

Management of childhood craniopharyngioma: can the morbidity of radical surgery be predicted?

Seventy-five children treated for craniopharyngioma between 1973 and 1994 were studied to demonstrate which pre- and intraoperative factors were indicative of a poor outcome as defined by a quantitative assessment of morbidity. This involved a retrospective review of 65 patients and a prospective study of 10 patients focused on clinical details and cranial imaging and a follow-up "study assessment" of 66 survivors performed over the last 2 years. As part of the assessment, 63 patients underwent magnetic resonance imaging with a three-dimensional volume acquisition sequence 1.5 to 19.2 years after initial surgery. Predictors of high morbidity included severe hydrocephalus, intraoperative adverse events, and young age ( < or = 5 years) at presentation. Predictors of increased hypothalamic morbidity included symptoms of hypothalamic disturbance already established at diagnosis, greater height ( > or = 3.5 cm) of the tumor in the midline, and attempts to remove adherent tumor from the region of the hypothalamus at operation. Large tumor size, young age, and severe hydrocephalus were predictors of tumor recurrence, whereas complete tumor resection (as determined by postoperative neuroimaging) and radiotherapy given electively after subtotal excision were less likely to be associated with recurrent disease. Based on these findings, the authors propose an individualized, more flexible treatment approach whereby surgical strategies may be modified to provide long-term tumor control with the lowest morbidity.

Frameless image-guided stereotactic brain biopsy procedure: diagnostic yield, surgical morbidity, and comparison with the frame-based technique.

OBJECT: The gold standard for stereotactic brain biopsy target localization has been frame-based stereotaxy. Recently, frameless stereotactic techniques have become increasingly utilized. Few authors have evaluated this procedure, analyzed preoperative predictors of diagnostic yield, or explored the differences in diagnostic yield and morbidity rate between the frameless and frame-based techniques. METHODS: A consecutive series of 110 frameless and 160 frame-based image-guided stereotactic biopsy procedures was reviewed. Associated variables for both techniques were reviewed and compared. All stereotactic biopsy procedures were included in a risk factor analysis of nondiagnostic biopsy sampling. Frameless stereotaxy led to a diagnostic yield of 89%, with a total permanent morbidity rate of 6% and a mortality rate of 1%. Larger lesions were fivefold more likely to yield diagnostic tissues. Deep-seated lesions were 2.7-fold less likely to yield diagnostic tissues compared with cortical lesions. Frameless compared with frame-based stereotactic biopsy procedures showed no significant differences in diagnostic yield or transient or permanent morbidity. For cortical lesions, more than one needle trajectory was required more frequently to obtain diagnostic tissues with frame-based as opposed to frameless stereotaxy, although this factor was not associated with morbidity. CONCLUSIONS: With regard to diagnostic yield and complication rate, the frameless stereotactic biopsy procedure was found to be comparable to or better than the frame-based method. Smaller and deep-seated lesions together were risk factors for a nondiagnostic tissue yield. Frameless stereotaxy may represent a more efficient means of obtaining biopsy specimens of cortical lesions but is otherwise similar to the frame-based technique.

Comparison of mortality and morbidity in multiple versus singleton very low birth weight infants in a neonatal intensive care unit.

Multiple births in Korea have been increased recently as a consequence of increased infertility due to advancing maternal age at first birth, and increased use of assisted reproductive technology. Multiples suffer higher mortality and morbidity than singletons. However, it is not clear whether preterm multiple very low birth weight infants (VLBWI) suffer higher mortality and morbidity than comparable singletons. We evaluated 266 singleton and 113 multiple VLBWI to determine whether mortality and morbidity in multiple VLBWI were higher than those in comparable singletons. The rate of in vitro fertilization and cesarean section were significantly higher in multiples than singletons. The total and the adjusted mortality with gestational age and birth weight were not significantly different between the two groups. Maternal age and the incidence of respiratory distress syndrome, patent ductus arteriosus, bronchopulmonary dysplasia, intracranial hemorrhage (grade> or =3), cystic periventricular leukomalacia, and retinopathy of prematurity (stage> or =3) were not significantly different between the two groups, and the incidence of abnormal brainstem auditory evoked potential was higher among the singletons. These results suggest that multiple VLBWI do not suffer higher mortality or morbidity than comparable singletons.
