Comparison of the factors that influence obesity prevalence in three district municipalities of the same city with different socioeconomical status: a survey analysis in an urban Turkish population

BACKGROUND: To evaluate the obesity status, factors and comorbidities related to it in three district municipalities (DM) that compose city center of Bursa with inhabitants of different socioeconomic status. METHODS: A total of 1632 inhabitants >/=18 years of age were interviewed. The number of sample in each DM was obtained proportional to their populations by stratified sampling method. Among 1632, a total of 1543 subjects were included by random sampling and a questionnaire was filled in including demographic, social and behavioral features. RESULTS: The participants living in DM with the highest socioeconomical status (SES) score and level of education had the lowest body mass index (BMI) and body fat percentage (%BF) compared to other DMs. The lowest obesity prevalence (30.8% vs. 36.4% and 39.3%) in that DM was possibly due to younger age, lower female ratio, more active professional, higher percentage of smoking, more consumption of vegetables, olive or corn oil, and less carbohydrate. For the evaluation of the factors that may influence obesity risk, we investigated the effects of these factors in men and women separately with logistic regression model. Sedentary life style and dyslipidemia (DL) in men, being unemployed, having lower level of education and having hypertension (HT) in women and familial obesity in both gender were found to be related to increased obesity risk. CONCLUSIONS: The prevalence of obesity in Bursa is increasing although inhabitants are taking some precautions parallel to their socioeconomical and educational levels. Obesity is becoming a more alarming public health problem in Bursa and Turkey like in most other parts of the world, which forces us to invent new prevention policies. Besides, the results of our study highlight the fact that especially female education requires more attention for decreasing obesity prevalence in coming generations.     

An Assessment of the Effects of Two Types of Bioresorbable Barriers to Prevent Postoperative Intra-Abdominal Adhesions in Rats

Purpose This study assessed and compared the efficacy of two types of bioresorbable membranes in the prevention of postoperative adhesion under clean contaminated and bacterial peritonitis conditions using a cecal ligation and puncture model in rats. Methods Wistar albino rats (n = 72) were divided into six groups. Bacterial peritonitis was induced using a cecal ligation and puncture model in groups 2, 4, and 6. Groups 1, 3, and 5 served as controls for clean contaminated procedures in the absence of bacterial peritonitis. Groups 1 and 2 were the untreated clean contaminated and bacterial peritonitis groups and served as controls for the effect of the bioresorbable membranes in each condition. In groups 3 and 4, a 1.5 × 3 cm USP glycerol/sodium hyaluronate/carboxymethylcellulose membrane was wrapped around the cecal resection area and a 2 × 4 cm membrane was left under the incision. The oxidized regenerated cellulose membrane was similarly applied in groups 5 and 6. Four weeks later, the adhesions were evaluated. In addition, fibrosis and inflammation were observed histopathologically. Results Adhesion development (P = .008), fibrosis (P = .008), and inflammation (P = .0001) differed among the groups. Both materials increased adhesion formation in the bacterial peritonitis condition. Increased fibrotic activity was detected in all material-applied groups under both conditions. In addition, more inflammation was detected in the groups that received the application of a material, especially in the presence of bacterial peritonitis. Conclusion Neither material prevented adhesions in clean contaminated conditions. Moreover, they increased adhesion formation in bacterial peritonitis.     

Prekallikrein-Kallikrein conversion rate as a predictor of contrast material catastrophies

An in vitro is described that attempts to detect patients with a potential for adverse systemic reactions to contrast material. This test involves measuring the rate of conversion of prekallikrein to kallikrein under certain standard conditions. In a preliminary retrospective study, the test could be used to identify such patients with a sensitivity of 88%, a specificity of 82%, and a predictive value of 79%.     

Anatomical variations as potential risk factors for ulnar tunnel syndrome: a cadaveric study

The aim of this study was to assess the anatomical variations, especially the anomalous muscles passing through Guyon's canal and the fibrous arch forming the piso-hamate hiatus, which may play a role in ulnar tunnel syndrome. We have also focused on the relation of these structures with specific concern to the ulnar nerve. Nineteen embalmed cadavers (37 hands and forearms) were dissected. A fibrous arch extending between the pisiform and the hook of the hamate was observed in 21 hands. In majority of the cases flexor digiti minimi muscle was found to originate only from this arch. An anomalous muscle was disclosed in six hands with four of them passing through the piso-hamate hiatus with the deep branch of the ulnar nerve. In two of four cases, the superficial branch of the ulnar nerve was also accompanying the deep branch of the ulnar nerve beneath the anomalous muscle and through the piso-hamate hiatus. Because these anomalous muscles were generally found to course through the piso-hamate hiatus with the branches of the ulnar nerve, we conclude that the distal portion of the Guyon's canal has a relatively higher risk for ulnar nerve entrapment. We believe that surgeons operating on this region should take into account these various anatomic structures.     

Delayed gastric emptying in gastroesophageal reflux disease: the role of malrotation

The association between gastroesophageal reflux (GER) and intestinal malrotation (IM) has been well described. Delayed or impaired gastric emptying in IM is thought to be a contributing factor in the development of gastroesophageal reflux disease (GERD). The current study assessed the role of malrotation in delayed gastric emptying in children with GERD. We also evaluated the interactions between GERD, malrotation, gastric pH abnormalities, and gastric dysmotility. Sixty-seven patients between 1 and 5 years of age (mean 3.08±1.2) and with symptoms of GER, such as emesis, reactive or recurrent lung disease, and/or growth retardation, were studied in 2001–2005. Upper and lower gastrointestinal contrast studies were performed for the diagnosis of malrotation. Gastric motility was evaluated with a liquid gastric emptying protocol. GER was documented by upper gastrointestinal studies, scintigraphy, and/or 24-h pH monitoring. In our series of 44 children with GERD, there was an unexpectedly high incidence of IM: 54.5% (24/44). IM has previously been known to occur in 25% of patients with GERD. GERD was found in 24 (82.7%) of 29 patients with IM. Mean nuclear gastric emptying (MNGE) was 51.6±8.04 min in patients with isolated GERD and 96.6±20.5 min in children with IM and GERD. There was a statistically significant difference in MNGE time (p<0.05) between children with primary GERD and in those with GERD and IM. Esophageal pH monitoring showed that mean fraction time below pH 4 was 7.06±1.1% in patients with isolated GERD and 14.7±4.1% in patients with IM and GERD. GERD is common in children between 1 and 5 years old. Using gastric emptying studies and esophageal pH monitoring, we have shown that gastric dysmotility and esophageal pH abnormalities are highly prevalent, especially in children with malrotation compared with children with isolated GERD. These findings suggest that malrotation is an important factor responsible for delayed gastric emptying in GERD. Hence, we recommend that all infants and children with GERD and delayed gastric emptying undergo careful evaluation for malrotation.     

Does Coronary Artery Size Really Matter?

OBJECTIVE: To evaluate ischemia in right ventricle (RV) in patients with small caliber of right coronary artery (RCA). PATIENTS AND METHODS: The study population consisted of 60 consecutive patients undergoing coronary angiography within 3 months. The patients were divided into three different groups according to lumen diameter of RCA and coronary dominance. Group 1, 2, and 3 consisted of patients with small diameter of RCA, dominant RCA, and dominant circumflex artery, respectively. RV ischemia was assessed by using pulse-wave tissue Doppler sampling obtained from RV free wall close to the lateral tricuspid annulus at the apical four-chamber view during dobutamine stress echocardiography (DSE). RESULTS: When the mean systolic velocity percentages of increase from low to peak dose dobutamine in patients with small RCA were compared to those of other groups, statistically significant difference was found between group 1 and the other groups (P = 0.007 for group 1 vs group 2; P = 0.01 for group 1 vs group 3). The mean systolic velocity at peak dobutamine dose of patients with small caliber of right coronary artery was statistically lower than the other groups (P = 0.001 for group 1 vs group 2, P < 0.001 group 1 vs group 3). CONCLUSIONS: There are a group of patients with small diameter of RCA causing probable ischemia in RV and small caliber of RCA can really matter in these patients.
