Relationship of socio-economic inequality and overweight with non-communicable diseases risk factors: A study on underprivileged population.

BACKGROUND: Out of every five deaths in India three are due to Non-Communicable Diseases (NCDs). Two major modifiable risk factors for NCDs are overweight and socioeconomic inequality. This study assesses the burden of various NCDs risk factors and their relationship with socioeconomic inequality and overweight among the underprivileged population. AIM: To compare the different Non-Communicable Diseases risk factors with socioeconomic inequality and overweight. To evaluate the relationship between socioeconomic inequality and body weight with NCDs. MATERIALS AND METHODS: A cross-sectional study incorporating 241 random sample of participants was assessed using WHO Stepwise approach to NCD risk factor surveillance. Anthropometric measurements and biochemical analysis of 12 h of fasting venous blood samples were done. Data were analyzed using Stata version 16 and Graph Pad Prism 8, using two-sided significance tests at the 5% significance level. RESULTS: The study finds a 10-fold higher risk of tobacco use ( AOR = 10.18, C.I = 2.79 - 37.10) and 5 times higher risk of alcohol use AOR = 5.57, C.I = 1.25 - 24.65) among people with poor SES compared to higher SES. A significant correlation was observed between BMI, LDL cholesterol ( r = -16.0; P = 0.009) and HDL cholesterol (r = 18.0;P = 0.006) with socioeconomic status. The study finds that for individuals who were overweight the odds of systolic blood pressure (AOR = 2.11, C.I = 1.03-4.31), fasting blood sugar (AOR = 3.84, C.I = 1.30 -11.32), triglyceride level, (AOR = 2.20, C.I = 1.18 - 4.09) high-density lipoprotein ( AOR = 2.63, C.I = 1.26 - 5.46) were significantly higher compared to normal BMI individuals. CONCLUSION: The study showed that the socioeconomic patterning of the population is significantly associated with NCD risk factors. Obesity was closely linked with several major NCD risk factors.

Use of concept map as a reinforcement tool in undergraduate curriculum: An analytical study.

INTRODUCTION: Ever-expanding medical literature demands successful amalgamation of huge information and clinical practice for budding doctors. This study aimed to find the effectiveness of the concept map, a novel method of teaching to improve performance among undergraduate pharmacology students. METHODS: The undergraduate medical students pursuing pharmacology in 2017-18 in our institute was divided into two groups after stratified randomization based on the last semester grades. After a session of didactic lecture on 'Drugs affecting Calcium Metabolism' and a pre-test, one group was taught using traditional tutorial methods and another group using the concept map method. Finally, a post-test was taken and feedback received from the intervention group. RESULTS: A significant improvement of student performance was found in both groups using validated questionnaire from pre-test to post-test. There was no significant difference in the percentage of improvement between the groups. This finding was consistent in both Low scorers and High scorers of the previous semester examination. Students found the new method better in terms of understanding the concept and interactivity. CONCLUSIONS: Concept mapping encourages the students to actively participate and get a comprehensive and accurate overview of the topic, but the improvement in performance in the test was not evident.

Establishment of reference interval of serum prolactin in an Indian population.

BACKGROUND: Reference data on serum prolactin levels based on a representative Indian sample are still lacking. The western normative laboratory values used for clinical diagnosis may not be applicable to Indian population. The objective of the study was to measure the serum prolactin levels in healthy Indian male and female in order to establish reference interval and to compare with the available reference intervals. It is a cross- sectional study done in West Bengal, India. MATERIALS AND METHODS: Based on the history, clinical examination and laboratory investigations, serum prolactin levels of 1316 apparently healthy subjects were estimated by microplate immunoenzymometric assay using pooled serum. Statistical analysis was performed using SPSS software. RESULTS: The serum prolactin levels for all ages were 10.7 ± 3 ng/ml in healthy male and 11.6 ± 2.8 ng/ml in healthy female. Decade-wise analysis of serum prolactin level in female showed a steady increase from 20-29 years to advancing decades until 4(th) decade and thereafter declines steadily although it was not same for male. CONCLUSION: Our study will help each laboratory to formulate their own reference interval for prolactin. As of now they were dependent either on the values written on the kit-literature supplied by the reagent manufacturing company or the reference intervals of foreign population.

Role of Nitric Oxide in Salmonella Infection.

Nitric oxide (NO) derivative of l-arginine is an important signaling molecule that mediates a variety of essential physiological processes including vasodilation neurotransmission, and host cell defense. Many types of cells produce NO e.g., smooth muscle cell, endothelial cell, and leukocytes. Host defense functions are known for many bacterial and parasitic infections. In the present study we estimated the levels of serum NO in cases of salmonellosis and in controls. The nitric oxide was estimated by cadmium reduction method, Griess reaction. We observed that in controls the level of NO was (22 ± 2.06) µmol/l and in cases the level was (137.49 ± 29.84) µmol/l. The level of NO was significantly higher than controls (p < 0.001). The raised level of NO could be accounted for by host response to the infection. The host rapidly expresses iNOS, which in turn produces an excess amount of NO. Its cytotoxic effect is by its reactive nitrogen oxide derivative e.g., peroxynitrite. Apart from this it also has anti apoptotic functions. In future one can do follow up study of typhoid cases by bacterial culture.

Oxidised LDL, HDL cholesterol, LDL cholesterol levels in patients of coronary artery disease.

Coronary artery disease is a major cause of morbidity and has various risk factors. Lipid profile i.e. low HDL-cholesterol, high LDL cholesterol, high total cholesterol, high triglycerides playing important role in its causation. Recently interest has been shown in the oxidized fraction of LDL as one of the risk factors. In the present study 60 age and sex matched normal healthy individuals were taken as controls and 60 patients of CAD were taken. Cholesterol was measured by enzymatic method, HDL cholesterol by phosphotungstate precipitation method. Serum levels of LDL fraction of cholesterol was measured by a new and simpler method of precipitation. Result was expressed as mol/L of diene conjugates. It was observed that LDL cholesterol, VLDL cholesterol, total cholesterol, total cholesterol: HDL cholesterol, LDL cholesterol: HDL cholesterol were significantly raised and HDL cholesterol was significantly low in patients. (p<0.001). Though HDL cholesterol was significantly raised in females as compared to males in both the groups (p<0.001). Serum level of total cholesterol, oxidized LDL:HDL cholesterol were also raised significantly (p<0.05). The level of oxidized LDL showed an increasing trend in patients.
