Use of BODE Index to Assess Prognosis of Patients with COPD.

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation which is irreversible or partially reversible. COPD is associated with morbidity and increased mortality. The risk of death in patients with COPD is traditionally graded with the use of the forced expiratory volume in one second (FEV1), but it correlates better with recently developed the BODE index- (B) Body mass index; (O) airflow obstruction measured by the forced expiratory volume in one second (FEV1); (D) dyspnoea measured by the modified Medical Research Council (MRC) scale; and (E) exercise capacity measured by the 6 minute walk distance (6MWD). This prospective study was conducted in outpatient department of Sheikh Sayera Khatun Medical College Hospital, Goplaganj, Bangladesh from June 2016 to November 2018. Among total 126 patients, mean age was 60.63.0±10.65, male 94 and female 32, 94 smokers, 32 non-smokers. During the study period, 20 patients died, 12 from non-respiratory causes and 8 from pulmonary causes (corpulmonale and respiratory failure). All patients died from respiratory causes had BODE score 10. The higher the BODE score points, the higher the risk of death from respiratory causes.

Evaluation of stentangioplasty in university cardiac center.

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.

Fabrication of an all-polymer battery based on derivatized polythiophenes.

Conducting polymers that can be switched between an insulating neutral state and a conducting doped state are of interest for charge-storage applications such as secondary batteries. The authors report on the fabrication of an all-polymer battery incorporating derivatized polythiophene films electropolymerized onto graphite-coated polymeric supports and a polymer gel electrolyte film. The cells had discharge voltages of about 2.4 V and capacities of 9.5 to 11.5 mAh g-1. The elimination of any metallic components or liquids and the lightweight and flexible construction provide a unique alternative for secondary battery technology.
