    Abstract: The tribological performance of 5xxx series aluminum alloys with ternary zirconium is evaluated at ambient conditions under dry, wet and saline environment. The experiment has been done using a Pin-on-Disk apparatus under an applied load of 20N. The sliding distances varies ranging from 116m-2772m at a sliding velocity of 0.385 ms-1. The results show that presence of Mg and Zr into this alloy helps to increase their strength and wear resistance under dry sliding condition. But they significantly suffer under wet and corrosive environment due to formation of β-phase Al3Mg2, to slip bands and grain boundaries which may lead to and stress-corrosion cracking. The variation of friction coefficient is observed in wet and corrosive environment due to the formation of oxidation film, lubrication, and corrosion action in solution. The SEM fracture surface shows that brittle Al3Mg2 phase initiate the brittle fracture surface for Al-Mg alloy and Zr addition accelerate the brittleness of the alloy owing the fine precipitates of Al3Zr.

    Abstract: The radical cure of Plasmodium vivax requires treatment with an 8-aminoquinoline drug, such as primaquine and tafenoquine, to eradicate liver hypnozoite stages, which can reactivate to cause relapsing infections. Safe treatment regimens require prior screening of patients for glucose-6-phosphate dehydrogenase (G6PD) deficiency to avoid potential life-threatening drug induced haemolysis. Testing is rarely available in malaria endemic countries, but will be needed to support routine use of radical cure. This study investigates end-user perspectives in Bangladesh on the introduction of a quantitative G6PD test (SD Biosensor STANDARD™ G6PD analyser) to support malaria elimination. Methods The perspectives of users on the SD Biosensor test were analysed using semi-structured interviews and focus group discussions with health care providers and malaria programme officers in Bangladesh. Key emerging themes regarding the feasibility of introducing this test into routine practice, including perceived barriers, were analysed. Results In total 63 participants were interviewed. Participants emphasized the life-saving potential of the biosensor, but raised concerns including the impact of limited staff time, high workload and some technical aspects of the device. Participants highlighted that there are both too few and too many P. vivax patients to implement G6PD testing owing to challenges of funding, workload and complex testing infrastructure. Implementing the biosensor would require flexibility and improvisation to deal with remote sites, overcoming a low index of suspicion and mutual interplay of declining patient numbers and reluctance to test. This approach would generate new forms of evidence to justify introduction in policy and carefully consider questions of deployment given declining patient numbers. Conclusions The results of the study show that, in an elimination context, the importance of malaria needs to be maintained for both policy makers and the affected communities, in this case by ensuring P. vivax , PQ treatment, and G6PD deficiency remain visible. Availability of new technologies, such as the biosensor, will fuel ongoing debates about priorities for allocating resources that must be adapted to a constantly evolving target. Technical and logistical concerns regarding the biosensor should be addressed by future product designs, adequate training, strengthened supply chains, and careful planning of communication, advocacy and staff interactions at all health system levels.

    Abstract: Background: Although transradial approach (TRA) has better outcome and reduced vascular complications, radial artery occlusion (RAO) is now a major concern as it limits future radial artery use for further TRA, for use as a conduit during CABG, for invasive hemodynamic monitoring and for creation of arteriovenous fistula for hemodialysis in CKD patients. Vascular doppler study is the most accurate method for evaluation of RAO and yet this is not practiced in our population. Objectives: To detect the frequency and identify the predictors of RAO after coronary procedure through TRA. Methods: This cross-sectional analytical study was done in the department of cardiology, NICVD from July-2015 to June- 2016 by including a total 125 patients undergoing coronary procedures (CAG and/or PCI) through TRA. Vascular doppler study of the radial artery were performed before and one day after the procedure. RAO was defined as an absence of antegrade flow and monophasic flow on doppler study. Univariate and multivariate logistic regression analysis were done to evaluate the predictors of RAO. Results: On the day after the procedure, radial artery vascular doppler examination revealed RAO in 12 (09.6%) patients. On univariate analysis female gender (p= 0.038), diabetes mellitus (p= 0.024), prolonged hemostatic compression for more than 02 hours after sheath removal (p= 0.003) were identified as predictors of RAO. Interestingly hypertension, low BMI, smaller radial artery diameter and use of reprocessed sheath were not identified as predictors of RAO. On multivariate analysis diabetes mellitus (p= 0.016), prolonged hemostatic compression for more than 02 hours after sheath removal (p= 0.004) were found as independent predictors for RAO. Conclusion: Frequency of RAO was 09.6% after coronary procedure through TRA. Diabetes mellitus and hemostatic compression after sheath removal for more than two hours were identified as independent predictors of RAO. Strategies should be taken from patient selection for TRA to end of hemostatic compression removal to prevent RAO. Bangladesh Heart Journal 2019; 34(2) : 111-117

    Abstract: Banking performance has been regarded as a crucial factor of economic growth. Banks collect deposits from surplus and provide loans to the investors that contribute to the total economic growth. Recent development in the banking industry is channelling the funds and participating in economic activities directly. Hence, academic researchers are gradually showing their concern on banking performance and its effect on economic growth. Therefore, this study aims to explore the academic researchers on this particular academic research article. By extracting data from the web of Science online database, this study employed the bibliometrix package (biblioshiny) in the ‘R’ and VOSviewer tool to conduct performance and science mapping analyses. A total of 1308 research documents were analysed, and 36 documents were critically reviewed. The findings exhibited a recent growth in academic publications. Three major themes are mainly identified, efficiency measurement, corporate governance effect and impact on economic growth. Besides, the content analysis represents the most common analysis techniques used in the past studies, namely DEA and GMM. The findings of this study will be beneficial to both bank managers and owners to gauge a better understanding of banking performance. Meanwhile, academic researchers and students may find the findings and suggestions to study in the banking area.

    Abstract: Background and Objective: Trans-radial approach of coronary catheterization has been increasingly used as an alternative to transfemoral approach due to less vascular complications, earlier ambulation and improved patient comfort. The aim of the study was to compare procedural and post procedural vascular complications in patients with percutaneous coronary intervention by trans-radial and transfemoral approach. Methods: This observational comparative study was conducted in the National Institute of Cardiovascular Diseases between June 2015 to May 2016. A total of 180 patients were categorized into two groups according to the approach of the percutaneous coronary intervention (PCI). Group I comprising 90 patients who underwent trans-radial PCI and group II consists of 90 patients who underwent transfemoral PCI. Patients with an abnormal Allen’s test, acute coronary syndrome, history of coronary artery bypass surgery, chronic renal insufficiency or older age ( 〉 75 years) were excluded. Results: Patient demographics were the same in both groups. The mean procedural time in min (37.44±5.13 vs 34.14±4.42, p=0.004) and fluoroscopy time in min (21.62±4.11 vs 17.55±2.78, p=0.02) were more in TR-PCI group but the mean haemostasis time in min (7.58±1.11 vs 15.59±3.33, p=0.005) and ambulation time in hour (0.00±0.00 vs 15.59±3.33, p= 〈 0.001) were more in TF-PCI group. Significant arterial spasm following puncture (6.7% vs 0%, p=0.01) were found in trans-radial group but access site bleeding during procedure (2.2% vs 8.9%, p=0.04) were more in TF-PCI group. After the procedure major hematoma (0% vs 4.4%, p=0.04), minor hematoma (5.7% vs 14.4%, p=0.04) and ecchymosis (4.4% vs 13.3%) were significant in TF-PCI group but vessel occlusion (5.7% vs 0%, p=0.02) were significant in TR-PCI group. The mean hospital stays, day (1.64±0.42 vs 2.54±0.62) were more in TF-PCI group. Conclusion: TR-PCI is safe in respect of procedural and post procedural vascular complications. Trans-radial procedure leads to improved quality of life after the procedure and thus gives much comfort to the patient. It also shortened mean duration of hospital stay. So, trans-radial approach is an attractive alternative to conventional transfemoral approach. Bangladesh Heart Journal 2019; 34(2) : 86-91

    Abstract: Antibiotic resistance poses a great threat to global health, especially in low- and middle-income countries with a high infectious disease burden and limited resources. In spite of regulations, antibiotics are sold in many settings as non-prescription medicines, resulting in inappropriate use and resistance. Objective This study aimed to investigate the current status of access and use of antibiotics in rural Bangladesh, by exploring the perspectives and sales practices of antibiotic drug dispensers. Methods We used a mixed methods approach (qualitative and quantitative). We mapped and characterized antibiotic purchasing and dispensing sites in the Matlab Health and Demographic Surveillance System catchment area. Furthermore, we investigated the volume of provision of systemic antibiotics in 10 drug outlets. We held 16 in-depth interviews with randomly selected antibiotics dispensers. Interviews explored factors associated with antibiotic selling. Responses were transcribed, coded for themes, and summarized. We used ATLAS.ti 5.2 for conducting a thematic analysis. Results A total of 301 antibiotic dispensers were identified, of whom 92% ( n  = 278) were private and 8% ( n  = 23) public. 52% ( n  = 155) operated informally (i.e. without legal authorization). In order to promote and survive in their business, dispensers sell antibiotics for a range of conditions without a qualified physician’s prescription. Factors that facilitate these inappropriate sales include lack of access to healthcare in the rural community, inadequate doctor: population ratio, limited dispenser knowledge, poor pharmacovigilance concerning safety of self medication, lack of enforcement of policies, financial benefits for both customers and dispensers, and high dependency on pharmaceutical companies’ information. Conclusion Dispensers in rural Bangladesh sell antibiotics inappropriately by ignoring existing national regulations. They operate the antibiotic sales without facing any legal barriers and primarily with a view to sustain their business, resulting in inappropriate sales of antibiotics to the rural community. The influence of the drug industry needs to be replaced with evidence-based, not commercially driven information. Awareness programs for antibiotic providers that promote understanding of antibiotics and antibiotic resistance through tailored interventions may be helpful in changing current antibiotic sales practices.
