ABSTRACT
Nitrate-nitrogen and ammonium-nitrogen concentration were evaluated to assess the current nutrient condition of an ecologically as well as economically important wetland of Bangladesh. The contamination condition of surface water nitrate and ammonium of Hail Haor wetland was assessed to understand its probable risk to human health using the water samples collected from total-fifty monitoring stations, 25 each for two different seasons within 2018 to 2019. Nitrate concentration was measured using the spectrophotometer by colorimetric method, whereas ammonium was quantified using the micro Kjeldahl's distillation method. Statistical and geo-spatial analysis revealed an extensive understanding of the temporal and spatial variability as well as possible source identification of the nutrients in the studied area. Medium to a low level of nitrate ranging from 0.95 up to 9.25 mg/L and high ammonium with values from 0.32 up to 1.92 mg/L was a sporadic trend observed in wetland water, with low water season having more concentration than that of wet high water season. Hazard quotients (HQ) obtained from wetland water for four individual age groups recognized wetland water to be safe for consumption (HQ<1) based on its nitrate level. Wetlands can provide valuable ecosystem services, conserve the native and exotic wetland inhabitants and mitigate flood along with their purifying properties of nutrient removal to lessen the public health concerns about nitrate-nitrogen in drinking water. Therefore, appropriate rein in measures, incentivizing water use efficiency, and continuous monitoring of water quality will ensure safety for wetland habitats, also may aware of the risks or opportunities associated with using wetland water for both drinking and agricultural use.
ABSTRACT
Back ground: Reduction of coronary heart disease (CHD) risk through the modification of risk factors has a strong effect on clinical practice. The introduction of 3-hydroxy-3-methylglutaryl coenzyme-A (HMG-CoA) reductase inhibitors (statins) has significantly advanced the treatment of hypercholesterolemia and in reduction of cardiovascular events and total mortality rates. Among the available statins, Fluvastatin is a newer, synthetic, second generation, potent lipid lowering agent and widely accepted in diverse population. However the safety profile and efficacy was not assessed in Bangladeshi population, a population significantly different from Caucasian population where most studies were done. Current study aimed at evaluating the safety and efficacy of fluvastatin in the specified population. Methods: The study is an open-label, multicenter, quasi experimental study conducted among 162 adult patients suffering from hypercholesterolemia. After through baseline evaluation, the patients were given with Fluvastatin 80 mg once daily for 3 months. All the patients were assessed twice, before and after treatment. Data on demography, of relevant medical history and of physical examination were collected in the both the visit along with data on relevant lipid parameters (Total Cholesterol, LDL-C, HDL-C and TG) were collected at final visit. Safety was assessed by evaluating adverse events, as well as laboratory abnormalities, including liver aminotransferases. Results: Serum total cholesterol was found to be significantly reduced and across two assessments the reduction was 51.2 units (P<.001). Average reduction in LDL-cholesterol was around 40 units (P<.001). Most significant reduction (140.0±305.8 units) was seen in serum LDL cholesterol (P<.001). However; no statistically significant reduction was seen in HLD cholesterol. Safety of fluvastatin was assessed by evaluating the adverse events, as well as through laboratory abnormalities, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Comparison of aminotransferase level was done before and after treatment through paired t test, Neither ALT nor the AST showed statistically significant rise after 3 months treatment of fluvastatin (P>.05). Out of 162 study participant 4.3% had their treatment interrupted, of which 1 (0.62%) had to cease treatment due to lack of efficacy, 1 (0.62%) experienced adverse event, 2 (1.24%) didn’t return to follow-up and 3 (1.86%) patients requested their physician to cease the treatment. Conclusion: Three month treatment with Fluvastatin XL 80 mg reduces most of lipid parameter of lipid profile (Total cholesterol, Triglyceride and LDL) significantly. The drug is found to be well tolerated with minimal adverse event during the course of treatmen
ABSTRACT
In this ongoing prospective study conducted in University Cardiac Center, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from July 2004 to January 2006. Fifty (50) patients (mean age 56+/-7.2 years) underwent stentangioplasty were evaluated. The study group of 50 patients consisted of 42 (84%) men and 08 (16%) women. The aim of this study was to evaluate in-hospital success, failure and complications during the procedures. About risk factors 19(38%) had hypertension, 13(26%) were smoker, 11(22%) suffered from diabetes mellitus, 05(10%) had family history of ischaemic heart disease. Average left ventricular ejection fraction was 54+/-7. Target vessel percutaneous coronary angioplasty (PTCA) were done in 61 vessel, intracoronary stent implanted in 58 vessels, direct stenting were done in 35 cases, failed PTCA were in 03(6%) cases and two had dissection. The native vessels had a mean reference diameter of 2.91 mm and their luminal diameter increased significantly after percutaneous coronary intervention (PCI). All the patients were discharged by one to three days of the procedure with improvement of their clinical condition. In conclusion, intracoronary stent deployment in coronary artery stenosis following balloon angioplasty is a valid and beneficial strategy with good in-hospital results.
