Influence of climate on semen quality: A retrospective study.

INTRODUCTION: World over studies are being done by different group of workers to understand the time of deliveries conducted. Surprisingly majority of deliveries were following a pattern, seasonally. Today in this busy world, couples choose comparatively a free time for delivery and preparation for conception is done accordingly. Apart from these, it is clearly shown majority of deliveries are conducted during a particular season. We hypothesised that the change in semen quality during different seasons is responsible for this phenomenon. MATERIALS AND METHODS: Present study conducted on semen quality included 12,408 semen samples collected from different laboratories of Bangalore city during 8 years (2000-2007) period of time and were analysed season wise. RESULTS: Results showed sperm concentration was significantly lower in monsoon than in winter season. Humidity and pressure influenced sperm count. Forward moving sperms were influenced by temperature and pressure. SUMMARY: The study concludes the change in birth rates seen during different season in a year is due to the quality of semen responsible for conception.

Estimation of Health Utility and Quality Adjusted Life Years in Bilateral Hand Transplantation: A Time Trade-off Study.

BACKGROUND: Hand transplantation and advances in the field of prostheses have opened new frontiers in the restoration of hand function among bilateral hand amputees (BHA). There is only scarce literature evaluating the health utility (HU) and quality adjusted life years (QALY) gained by bilateral hand composite tissue allotransplantation (CTA) or prosthesis over amputation. The study was focused on BHA restored with prosthesis or CTA. METHODS: The HU of three different health states (HS) namely, BHA, using prosthesis or with CTA and net QALYs gained by hand transplantation or prosthesis over amputation were computed by time trade-off (TTO) method among 236 study participants. RESULTS: Among 236 study participants, medical professional (120), general public (89), BHA (23), and bilateral hand transplant recipients (4) were included. The mean HU by TTO method among the study participants (n = 232) as BHA, using prosthesis or CTA was 0.34 (±0.24), 0.50 (±0.26) and 0.69 (±0.26) respectively. Bilateral hand CTA imparted an expected gain of 12.57 (±11.43) mean QALYs over amputation among the study participants. The subgroup analysis displayed higher mean HU in hand CTA recipient HS along with maximum QALY gained by CTA over amputation. CONCLUSIONS: Bilateral hand CTA HS stands above the other 2 HSs, namely BHA and prosthesis, in terms of the health utility. As demonstrated by QALY gain of 12.57, participants' valuation of health utility is notably higher for CTA with acceptance of lifelong immunosuppressant rather than for a state of uncompromised physical health with a bilateral hand amputation.

South Indian Cuisine with Low Glycemic Index Ingredients Reduces Cardiovascular Risk Factors in Subjects with Type 2 Diabetes.

Background: Inflammation is considered as a predictor of cardiovascular diseases in type 2 diabetes mellitus. No previous studies have investigated the effect of low glycemic index (LGI) recipes of South Indian cuisine on the risk factors of cardiovascular disease in patients with diabetes. Aim: The aim of this randomized controlled trial was to evaluate the improvement in cardiovascular risk factors and blood glucose control, in patients with type 2 diabetes, after intervention with recipes of Kerala cuisine, from locally available whole grain cereals, low in glycemic index. Method: This was a prospective and randomized controlled study that was conducted over a period of 24 weeks. A total of 80 participants were recruited from the Department of Endocrinology and Diabetes Outpatient in Kerala, South India. All 80 patients had type 2 diabetes, and were aged between 35 and 65 years. Participants were randomly assigned and advised to follow either a LGI diet plan (n = 40) or their usual diet, which served as a control group (n = 40). The advice was reinforced throughout the study period. Anthropometric, biochemical parameters which included glycemic and cardio-metabolic parameters were measured according to standard procedures. T-tests were conducted to compare the differences between intervention and control groups, and the Pearson correlation coefficient was used to evaluate associations between the variables. Results: There were significant differences (p < 0.05) between the intervention and control groups with respect to weight, HbA1c, insulin, triglycerides, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), high sensitivity C-reactive protein (hs-CRP) and apolipoprotein B (ApoB). There was also a positive correlation between weight and blood glucose variables. ApoB was positively correlated with lipid profile and insulin levels. Conclusions: The long-term implementation of LGI diet of Kerala cuisine has been found to promote weight loss, enhance insulin sensitivity and reduce the cardiovascular risk.

The Effect of a Low GI Diet on Truncal Fat Mass and Glycated Hemoglobin in South Indians with Type 2 Diabetes-A Single Centre Randomized Prospective Study.

BACKGROUND: There has been no previous study that has investigated the effect of a low glycemic index (LGI) diet with local recipes of South Indian cuisine on the body fat composition using dual-energy X-ray absorptiometry (DXA). Truncal obesity has been associated with the risk of metabolic disorders and cardiovascular diseases. AIM: The aim of this study was to examine the effect of a low GI diet on glycemic control and body composition in people with type 2 diabetes in South India. METHOD: This was a prospective and randomized controlled study that was conducted over a period of 24 weeks. A total of 40 participants were recruited from the Department of Endocrinology and Diabetes Outpatient in Kerala, South India. All the patients had type 2 diabetes and were randomly assigned and given advice and instructions to follow either a low GI diet plan (n = 18) or their usual diet, which served as control (n = 18). The advice was reinforced throughout the study period. Dietary compliance was evaluated based on a 24 h dietary recall at weeks 3, 11, 12, 18, 23, and 24. The age of the subjects ranged from 35 to 65 years. Anthropometric, body composition, and cardio-metabolic parameters were measured according to standard procedures. T-tests were conducted to compare differences between intervention and control groups and the Pearson correlation coefficient was used to evaluate associations between the variables. RESULTS: There were significant reductions (p < 0.05) in the low GI diet compared to the control group with respect to weight, body mass index (BMI), and triceps skinfold thickness. Similarly, significant reductions were observed in the low GI diet group with respect to region, total fat, android, and gynoid fat mass and the differences between the groups were significant at p < 0.05. There was also a positive correlation between BMI and android fat mass (r = 0.745), total fat mass (r = 0.661), total truncal mass (r = 0.821), and truncal fat (r = 0.707). There was a significant reduction in glycated hemoglobin in the low GI diet group compared to the control group at p < 0.05. CONCLUSION: This study has demonstrated that there was a significant reduction (p < 0.05) of truncal obesity and glycated hemoglobin in patients with type 2 diabetes on a local diet of South Indian cuisine with low GI compared with the control.

Alcoholic chronic pancreatitis and alcoholic liver cirrhosis: differences in alcohol use habits and patterns in Indian subjects.

OBJECTIVES: Alcohol abuse is a risk factor for both liver cirrhosis and chronic pancreatitis. However, less than 15% of heavy drinkers develop these complications. Coexistence of cirrhosis and pancreatitis in the same patient is considered uncommon. We compared drinking patterns and related patient factors in patients with alcoholic liver cirrhosis and alcoholic chronic pancreatitis. METHODS: A prospective evaluation of 307 patients (all men: 188 with alcoholic liver cirrhosis and 119 with alcoholic chronic pancreatitis) was conducted over a 7-year period using a detailed alcohol assessment proforma. Assessment of demographic features, diet, and other habits like tobacco smoking were recorded. RESULTS: Patients with alcoholic liver cirrhosis were older. The mean ± SD age in alcoholic liver cirrhosis was 52.4 ± 9.16 years and 47.1 ± 9.78 years (P < 0.001) in alcoholic chronic pancreatitis. The mean ± SD age when they started drinking was similar in both groups (22.8 ± 5.32 years and 24.3 ± 6.94; P > 0.05). The mean ± SD duration of drinking was higher in the cirrhosis group (29.5 ± 10.25 years) than in the pancreatitis group (21.5 ± 9.61 years) (P < 0.001). Fifty-nine percent of cirrhosis and 75% of pancreatitis were heavy tobacco smokers (P = 0.004). CONCLUSIONS: There are distinct differences in drinking patterns and related patient factors between alcoholic liver cirrhosis and alcoholic chronic pancreatitis, suggesting the need to orient different interventional strategies.

Impact of integrated amrita meditation technique on adrenaline and cortisol levels in healthy volunteers.

THE OBJECTIVE WAS TO FIND OUT THE EFFECT OF INTEGRATED AMRITA MEDITATION TECHNIQUE (IAM) ON THE STRESS HORMONES: adrenaline and cortisol. One hundred and fifty healthy subjects were randomized into three groups. Blood was collected at 0 hour, 48 hours, 2 months, and 8 months after the first visit. Adrenaline was analyzed by ELISA and cortisol by Chemiluminescent method. In the IAM, PMR and control groups 44, 44, and 36 came, respectively, for the baseline visit. Within group, cortisol and adrenaline levels reduced in the IAM 48 hours onwards and the fall sustained until 8 months (P < .05). ANCOVA (Repeated measures) on adrenaline taking the four levels of observation showed a highly significant (P = .001) drop in the IAM group. The mean cortisol values between groups were not statistically significant (P = .138). IAM Technique was effective in reducing adrenaline and cortisol levels within group comparisons.

Chronic pancreatitis. A prospective nationwide study of 1,086 subjects from India.

CONTEXT: Chronic pancreatitis is common in India. However, its risk factors are not clear. There is sparse data on the current prevalence of tropical pancreatitis in India. OBJECTIVE: To undertake a prospective nationwide study of the risk factors and clinical profile of chronic pancreatitis. SETTING: Thirty-two major centers from different regions of India contributed data on 1,086 patients to a common online website (www.ipans.org). MAIN OUTCOME MEASURES: Risk factors, clinical features complications and treatment of chronic pancreatitis. RESULTS: Of the 1,086 subjects, complete data on risk factors were available for 1,033 subjects. Idiopathic pancreatitis was the most common form of pancreatitis (n=622; 60.2%) and alcoholic chronic pancreatitis accounted for about a third of the cases (n=400; 38.7%); the rest (n=11; 1.1%) had rare risk factors. Smoking and cassava intake were documented in 292 (28.3%) and 189 (18.3%) subjects, respectively. Using well-defined criteria, only 39 (3.8%)cases could be labeled as 'tropical pancreatitis'. Pain occurred in 971 patients (94.0%). Four hundred and eighteen (40.5%) subjects had diabetes mellitus. Of alcohol consumers, alcoholism and female gender were independent risk factors for diabetes in subjects with chronic pancreatitis (OR=1.48, P=0.003; and OR=1.75, P<0.001, respectively). The most common complications were pseudocysts (15.8%) and biliary obstruction (8.2%). Pancreatic cancer occurred in 42 subjects (4.1%). Ultrasound detected calculi in 69.7%, ductal dilatation in 63.4% and atrophy in 27.3%. The majority of patients were on medical therapy (n=849; 82.2%); endotherapy and surgery accounted for the rest. About 50% percent of the patients with diabetes required insulin (198/418). CONCLUSIONS: In this first nationwide prospective survey of chronic pancreatitis in India, idiopathic pancreatitis was the most common form, followed by alcoholic pancreatitis. The classical form of tropical chronic pancreatitis is becoming less common.
