Metabolic syndrome and its correlates: A cross-sectional study among adults aged 18� years in an Urban Area of West Bengal

Background: The prevalence of metabolic syndrome (MetS) is increasing dramatically of late, across all ages irrespective of gender, socioeconomic status, and ethnicity. People with MetS have twice the likelihood of developing and dying from cardiovascular disease and more than seven times the risk of developing diabetes. Objectives: This study was undertaken to determine the prevalence of MetS among adults who were in their first three decades of adulthood and to find out the risk factors of MetS among them. Methods: This was a community based cross-sectional study among 388 subjects aged 18� years selected by multistage random sampling in an area of Kolkata, India, from November 2016 to October 2018 over 2 years. Data collection was done using a structured questionnaire along with anthropometry, blood pressure measurement, and relevant blood tests. Physical activity was classified by the International Physical Activity Questionnaire Short-Form questionnaire. Data were analyzed using the Statistical Package for the Social Sciences (version 16.0), and descriptive statistics were calculated as frequency and percentage. Logistic regression was done to determine the strength of association between MetS and different risk factors. Results: The prevalence of MetS was 44.6% (35.4% in males and 55.6% in females), and female gender, poor economic status, sedentary lifestyle, poor diet, and addiction of tobacco were found to be the risk factors of MetS in the final model using multivariable logistic regression. Conclusion: This research revealed the high prevalence of MetS in the community. The effective primordial and primary level of prevention along with prevailing secondary or tertiary level of prevention should have been employed to curtail the epidemic of MetS.

Eosinophilic pancreatitis with pseudocyst.

Eosinophilic pancreatitis is a rare entity in patients having underlying systemic manifestations such as peripheral eosinophilia, elevated serum IgE levels and/ or eosinophilic infiltrates in other organs, including the gastrointestinal tract. We report a 38-year-old woman with peripheral eosinophilia in association with acute pancreatitis, pancreatic ascites and pseudocyst.

Hepatopulmonory syndrome--an uncommon and severe complication of certain liver diseases.

Hepatopulmonary syndrome (HPS) is charaterised by arterial hypoxaemia found mainly in association with chronic liver disease (most commonly cirrhosis of liver) but also rarely with acute liver diseases like fulminant hepatic failure or Budd-Chiari syndrome. The purpose of this article is to present an uncommon but grave complication mostly associated with cirrhosis of liver and to differentiate this entry from cyanotic heart diseases or certain lung conditions. Investigations include history and physical examination, certain biochemical tests, upper gastro-intestinal (GI) endoscopy, abdominal ultrasonography, liver biopsy and venacavography in appropriate cases. Finally, the suspected cases underwent arterial blood gas (ABG) analysis and contrast enhanced echocardiography (CEE) for confirmation of the diagnosis of HPS. Of the 123 cases of cirrhosis of liver, three cases of HPS (2.4%) were found-all of them being males. Also one male patient with inferior vena cava (IVC) obstruction amongst other causes presenting with HPS was encountered. As of now, no medical treatment has been proved to be useful and liver transplant remains the only hope for this disorder.

Effect of chitosan on lipid levels when administered concurrently with atorvastatin--a placebo controlled study.

In a placebo controlled trialthe lipid lowering effects of chitosan, a unique dietary fibre, was assessed when given along with atorvastatin 10 mg in patients with chronic coronary heart disease. Altogether 100 patients were studied. They were randomly allocated in two groups of 50 patients each. Patients of group A received atorvastatin 10 mg before dinner plus 2 g/day chitosan in two divided doses. The groupB patients received atorvastatin 10 mg plus placebo. Patients were followed up for a period of 6 weeks. There was significant reduction in mean body weight in group A patients (3.14% versus 1,29% of body weight, p<0.05). There was also a significant rise in HDL cholesterol value (3.8% versus 1.07%, p=0.02) in group A patients. However, there was no significant reduction in the mean values of total cholesterol, LDL cholesterol and triglyceride in the two groups, although group A patients showed marginally lower values.

Surface activity, lipid profiles and their implications in cervical cancer.

BACKGROUND: The profiles of lipids in normal and cancerous tissues may differ revealing information about cancer development and progression. Lipids being surface active, changes in lipid profiles can manifest as altered surface activity profiles. Langmuir monolayers offer a convenient model for evaluating surface activity of biological membranes. AIMS: The aims of this study were to quantify phospholipids and their effects on surface activity of normal and cancerous human cervical tissues as well as to evaluate the role of phosphatidylcholine (PC) and sphingomyelin (SM) in cervical cancer using Langmuir monolayers. METHODS AND MATERIALS: Lipid quantification was done using thin layer chromatography and phosphorus assay. Surface activity was evaluated using Langmuir monolayers. Monolayers were formed on the surface of deionized water by spreading tissue organic phase corresponding to 1 mg of tissue and studying their surface pressure-area isotherms at body temperature. The PC and SM contents of cancerous human cervical tissues were higher than those of the normal human cervical tissues. Role of PC and SM were evaluated by adding varying amounts of these lipids to normal cervical pooled organic phase. Statistical analysis: Student's t-test (p < 0.05) and one-way analysis of variance (ANOVA) was used. RESULTS: Our results reveals that the phosphatidylglycerol level in cancerous cervical tissue was nearly five folds higher than that in normal cervical tissue. Also PC and sphingomyelin SM were found to be the major phospholipid components in cancerous and normal cervical tissues respectively. The addition of either 1.5 microg DPPC or 0.5 microg SM /mg of tissue to the normal organic phase changed its surface activity profile to that of the cancerous tissues. Statistically significant surface activity parameters showed that PC and SM have remarkable roles in shifting the normal cervical lipophilic surface activity towards that of cancerous lipophilic component. CONCLUSION: The Langmuir monolayer technique was sensitive to detect changes in tensiometric profiles of cervical cancers and these could be modulated by alterations in phosphatidylcholine and sphingomyelin levels. Therapeutic strategies may be designed to modulate these tensiometric profiles and lipid constituents of cancerous tissues.

A study on micro-albuminuria--an independent risk factor for vasculopathy in diabetes mellitus.

Diabetes is becoming a serious threat to combat felt among the doctors of the world. India, in partcular is a vulnerable country contributing maximum number of cases to the global diabetic pool. Macro-and microvascular complications are important causes of mortality and morbidity. Micro-albuminuria is a surrogate marker for detetion of vasculopathy for which early detection and aggressive treatment can reduce mortality and morbidity. A small study was conducted to identify the usefulness of this marker in our setting which can be used as a cost-effective tool for detecting the dreadful complication early. This study has demonstrated that in presence of micro-albuminuria the vascular complications of diabetes definitely increase and it is more relevant in cases of type 2 diabetes irrespective of other parameters rendering it to be a independent risk factor. It also indicates that presence of this marker along with vasculopathy is time dependent ie, more the duration of the disease more is the complication.

Carotid intima media thickness: an independent marker for assessment of macrovascular risk in diabetic patients.

In view of the global epidemic of diabetes with India being the hottest reservoir of the disease, it was tried to identify carotid intima media thickness as a surrogate marker for atherosclerosis in diabetic subjects. The study becomes more relevant because diabetes is now considered a disease of the endothelium and a risk equivalent of coronary atherosclerosis (paradigm shift). The study incorporated 41 normotensive patients of diabetes and 31 age and sex matched controls. Plasma glucose and lipid profiles were assessed in all and the carotid intima media thickness was measured. Results were statistically analysed for significance and correlation coefficient between values of plasma glucose and carotid intima media thickness. Results clearly showed that carotid intima media thickness abnormality can pick up atherosclerosis even if the lipid parameters are nearly normal. So it crystallises from this small study that, as a non-invasive test carotid intima media thickness is a better and early predictor of atherosclerosis in diabetic subjects. It also revealed the linear relationship between both fasting and postprandial blood sugar with carotid intima media thickness.

Button battery ingestion.

Button batteries represent a special category of pediatric ingested foreign body because of the possibility of serious complications particularly if impacted in the esophagus. We report a case of a 3-year-old girl with severe mid esophageal burns due to a lodged battery. More awareness is required amongst physicians to avert such dangers and ensure prompt removal.

A study of bone mineral density in diabetes mellitus in eastern India.

To measure bone mineral density in diabetic patients at the time of clinical diagnosis of diabetes mellitus and to find out correlation, if any, with microvascular complication of diabetes mellitus and glycosylated haemoglobin, a study was conducted at Medical College and Hospital, Kolkata among 138 cases of diabetes and 212 controls. All patients were screened for ophthalmoscopy, routine blood and urine examinations. Bone ultrasound attenuation study of the calcaneus was performed in all cases. The bone ultrasound attenuation result was compared to a mean normal population result and expressed as Z score and T score. The age of diabetic patients varied from 11 years to 70 years. Of 138 diabetics, 32 (23.18%) had type 1 diabetes and rest type 2 diabetes. Forty-two diabetic patients had retinopathy, 42 nephropathy and 48 had neuropathy. Glycosylated haemoglobin was above 7% in 124 patients. The broadband ultrasound attenuation of type 1 diabetics ranged from 38 to 95 dB/MHz and in type 2 it was 35 to 104 dB/MHz. There was no statistically significant correlation between neuropathy, nephropathy, retinopathy and bone mineral density status. It was also found no correlation between glycosylated haemoglobin values and ultrasound attenuation.

Optimization of some additives to improve protease production under SSF.

In a locally isolated Rhizopus oryzae strain highest-production of protease (388.54/g wheat bran) was observed in presence of Tween-80 and dioctyl sodium sulfosuccinate individually at 40mg/g wheat bran concentration. Under solid state fermentation biotin (0.0025mg/g wheat bran); Ca2+ (0.05mg/g wheat bran) and 1-Naphthyl acetic acid (0.01mg/g wheat bran) also showed some inducing effect on the synthesis of the enzyme protease by solid state fermentation.

Zoonoses and bats: a look from human health viewpoint.

Bats are the most abundant and most widely distributed mammals on the Earth after humans. Except Antarctica and some small remote islands, they are prevalent worldwide. Although the actual role played by bats as reservoir or in disseminating zoonoses is still enigmatic a multitude of zoonotic diseases are known to be associated with bats. Such diseases including viral, bacterial, parasitic, fungal and rickettsial diseases, reported from all over the world including India have been briefed in this article as an informative approach because dramatically increased and diversified human activities during the last few decades perturbing natural ecosystems are enough to compel public health personnel to have an investigative look at these flying mammals.

Isolation of verotoxin producing Escherichia coli from diarrhoeal and urinary tract infection patients.

Fourty nine Escherichia coli strains, isolated from diarrhoeal and urinary tract infection (UTI) patients, attending Bareilly district hospital, Uttar Pradesh during October to December, 1998 were screened for verotoxin (VT) production by Vero cell assay. Five strains produced characteristic cytopathic effect on Vero cell line, of which 4 were from diarrhoeal and one was from UTI-patient. The level of VT-production varied widely. Antibiotic sensitivity tests revealed that the VT-producing E. coli (VTEC) were mostly sensitive to kanamycin, norfloxacin and nalidixic acid but resistant to ampicillin and tetracycline.

Postulated effects on water structure of some salts and protein denaturants as inferred from measurements of viscosity B coefficients: example of HbS polymerization.

Viscosity measurements have been performed on aqueous solutions of some solutes commonly used in biochemical practice, with a view to determine the B coefficients and their temperature dependence. The temperature dependence measured for some anions leads to a ranking of the latter in an order similar to that reported earlier from entropy data for their postulated efficiency in disrupting "water structure". The well known dependence of denaturing power of guanidinium salts on the anions is shown to be related to the temperature dependence of B coefficients. Urea and formamide do not appear from this criterion to be significantly "structure-breaking"; alkyl-substituted derivatives of urea and formamide, on the other hand, possess significant "structure-forming" properties. The results are of interest in relation to the known effects of salts and other solutes on the stability of protein structures in respect of denaturation, subunit dissociation or self assembly. A typical application is illustrated by studying the effect of two anions, namely nitrate and sulphate, on the polymerization of sickle cell hemoglobin (HbS). Nitrate, which is believed to disrupt water structure, acts as an inhibitor of HbS polymerization which, on the contrary, is favoured by sulphate, a postulated structure- former.

Location and mapping of an autosomal recessive mutation causing unique phenotypic change in Drosophila bipectinata.

In Drosophila bipectinata, flies with bilateral outgrowths on thorax were detected in sepia eye colour mutant stock. Such thoracic outgrowths have not been reported earlier in any species of Drosophila and appear to be unique phenotypic change in D. bipectinata caused due to autosomal recessive mutation. By using a double recessive mutant stock (se og) and a wild type stock, crosses were made and on the basis of recombination data of F1 females, the og mutation was mapped on the second chromosome of D.bipectinata. Further, D. bipectinata exhibits spontaneous male recombination in low frequency.

Interaction between selection and genetic drift in laboratory populations of Drosophila bipectinata.

To study the effect of selection and random genetic drift in laboratory populations of D. bipectinata, cut wing mutant and wild type stocks were crossed in several bottles. All the lines were maintained for several generations and in each generation the number of wild type and mutant flies was scored. Based on the number of two types of males, the frequency of cut gene and its normal allele was calculated for different bottles since ct is a sex-linked mutation and males are hemizygous. Interestingly, the cut gene was quickly eliminated in all the populations which is due to selection affecting fitness of two types of flies. However, there was considerable fluctuation in gene frequency among different populations and also there was increase in the cut gene frequency in certain generations as compared to previous generation which is caused due to effect of genetic drift which operates in small populations.
