Abstract
Asthma is a common pulmonary disorder characterizerized by airway inflammation, airway- hyper reactivity, and reversible airflow obstruction. The classic triad of symptoms is wheezing, chronic episodic dyspnea and chronic cough. The prevalence of asthma increased steadily over the latter part of the last century, first in the developed and then in the developing world. The number of people with asthma in the world may be as high as 334 million. Asthma in Bangladesh appears to be a substantial public health problem: an estimated 11.6 million people including 4.1 million children suffer from asthma-related symptoms. A cross sectional study was conducted from January 1999 to August 1999 on 5642 Bangladeshi people and another same study carried out from November 2009 to April 2010 on 8088 subjects. In 1999 the prevalence of asthma was 6.9% whereas in 2010 it is 6.96%. Airway resistance is always increased during the asthmatic attack. Airways obstruction, such as that caused by asthma, results in a reduced and variable Peak Expiratory Flow Rate (PEFR). PEFR is classically reduced in asthma. Recent asthma guidelines recommended the assessment of severity levels based on the most severe symptoms and peak expiratory flow rate. This descriptive type of cross-sectional study was done to find the changes of Peak expiratory flow rate in adult asthmatic patients and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty (50) male and 50 (fifty) female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh, Bangladesh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. PEFR was estimated by Wright's Peak flow meter. For statistical analysis unpaired student's 't' test was used. Mean PEFR were significantly decreased in study group in comparison to control group and the result was statistically significant (p<0.001). From this study, it may be concluded that peak expiratory flow rate was decreased in asthmatic patient and there was a significant relation of decline lung function.

Abstract
Asthma has been defined as a chronic inflammatory disorder of the airways that is associated with recruitment of inflammatory cells and the clinical development of wheezing, shortness of breath, chest tightness, and cough. The prevalence of asthma increased steadily over the latter part of the last century, first in the developed and then in the developing world. Current estimates suggest that asthma affects 300 million people worldwide, with a predicted additional 100 million people affected by 2025. This cross sectional study was conducted from January 1999 to August 1999 on 5642 Bangladeshi people and another same study carried out from November 2009 to April 2010 on 8088 subjects. In 1999 the prevalence of asthma was 6.9% whereas in 2010 it is 6.96%. Both asthma and hypertension are spastic disorders of smooth muscle, there is the similarities between these two diseases may predispose the individuals with one disease to the other. This descriptive type of cross-sectional study was done to find the Interaction between hypertension and asthma in adult and carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2016. Fifty (50) male and fifty (50) female adult asthmatic patients aged 18-60 years were included in the study group. They are enrolled from the Department of Medicine, Mymensingh Medical College, Mymensingh and also from locality. For comparison age matched 50 male and 50 female apparently healthy persons were also studied as control. Blood pressure was estimated by auscultatory method by sphygmomanometer. For statistical analysis unpaired student's 't' test was used. Mean blood pressure were significantly increased in study group in comparison to control group and the result was statistically significant (p<0.001). The study findings showed a high prevalence of hypertension among asthmatic patients than non asthmatic healthy persons. From this study, it may be concluded that hypertension and asthma are closely connected.

Abstract
In Bangladesh, morbidity and mortality due to non-communicable diseases (NCDs) has increased over the last few decades. Hypertension is an important risk factor for NCDs, specifically cardiovascular disease. The objective of this study was to assess prevalence and risk factors for hypertension and prehypertension among adults in Bangladesh. Data for this analysis were collected during the national NCD Risk Factor Survey of Bangladesh conducted in 2010 from a representative sample of men and women, aged 25 years or above. The survey adopted a multistage, geographically clustered, probability-based sampling approach. WHO STEPS questionnaire was used to collect data on demographics, behavioral risk factors, and physical measurements. Overall, 20% of the study population were hypertensive at study measurement. The prevalence of hypertension increased with age and body mass index(BMI). Twelve percent of the population were previously diagnosed with hypertension. Among these individuals, nearly half were not taking any medications to control their hypertension. Additionally, the prevalence of pre-hypertension was 43%, with higher levels among males, older age groups, and those with higher education, higher wealth index and high BMI. Predictors of hypertension, included older age, high BMI and diabetes comorbidity. Based on this study, we estimate that 1 out of 5 Bangladeshi adults have hypertension. The risk of hypertension increases with older age and high BMI. Additionally, prevalence of pre-hypertension is high in Bangladesh in both rural and urban areas. Findings from this study can be used to inform public health programming to control the spread of NCDs in Bangladesh.

Abstract
An experiment was carried out to study the density dependent growth of Thai sharpunti (Barbonymusgonionotus) for two months period. Three stocking densities such as 50/decimal, 100/decimal and 150/decimal representing treatment one (T1), treatment two (T2) and treatment three (T3), respectively were tested in three replications. A commercial diet (25% crude protein) was supplied twice daily throughout the study period up to satiation level. The total production of sharpunti was found 14.67 ± 2.05, 27.06 ± 3.09 and 36.87 ± 2.16 kg/decimal in T1, T2 and T3, respectively and they were significantly different (p<0.05) from each other. A higher net benefit of BDT 1079.50 was obtained from T2 where the stocking density was 100/decimal. The present study indicated that the growth and production of Thai sharpunti was density dependent in monoculture systems.Progressive Agriculture 28 (3): 249-252, 2017

Abstract
Coronary heart disease (CHD) is the most common cause of heart disease and is the single most important cause of premature death in developed world. Recognizing a patient with ACS is important because the diagnosis triggers both triage and management. cTnI is 100% tissue-specific for the myocardium and it has been shown to be a very sensitive and specific marker for acute myocardial infarction (AMI). Ventricular function is the best predictor of death after an acute coronary syndrome. It serves as a marker of myocardial damage, provides information on systolic function as well as diagnosis and prognosis. The study aimed at investigating the impact of elevated Troponin-I level on LV ejection fraction and in-hospital outcomes in patients with first attack of Non ST-segment Elevation Myocardial Infarction (NSTEMI). This prospective analytical study was conducted in the Department of Cardiology in Mymensingh Medical College Hospital from December 2015 to November 2016. Total 130 first attack of NSTEMI patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I - Patients with first attack of NSTEMI with good LV function (LVEF: ≥55%). Group II - Patients with first attack of NSTEMI with LV systolic dysfunction (LVEF: <55%). Then Troponin-I and LVEF levels were correlated using Pearson's correlation coefficient test. In this study mean Troponin-I of Group I and Group II were 5.53±7.43 and 16.46±15.79ng/ml respectively. It was statistically significant (p<0.05). Echocardiography showed that patients with high Troponin-I level had low ejection fraction (LVEF) and patients with low Troponin-I level had preserved ejection fraction (LVEF). Analysis showed that patients with severe left ventricular systolic dysfunction (LVEF <35%) had the highest level of Troponin-I with worse in-hospital outcomes and vice versa-the patients with the preserved systolic function (LVEF ≥55%) had the lowest levels of Troponin-I with better in-hospital outcomes. In our study, it also showed that the levels of Troponin-I had negative correlation with LV ejection fraction levels, with medium strength of association (r= -0.5394, p=0.001). The study enabled us to conclude that, the higher was the Troponin-I level, the lower was the LV ejection fraction level and thus worse in-hospital outcomes in first attack of NSTEMI patients.

Abstract
Post kala-azar dermal leishmaniasis (PKDL) is a skin manifestation which usually appears after visceral leishmaniasis. It is now proved that PKDL patients serve as a reservoir for anthropometric leishmanial transmission. Hence, to achieve the kala-azar elimination target set by the World Health Organization in the Indian Subcontinent, PKDL cases should be given priority. The goal of treatment for PKDL should be early reepithelizlization and rapid cure, but unfortunately this has been difficult to achieve, especially for patients with severe lesions. Therefore, we describe here four cases of PKDL who had widespread nodular and macular lesions and were treated with two cycles of LAmB doses with 20 mg/kg body weight divided into four equal doses (each dose contains 5 mg/kg) administered every alternate day. This treatment schedule achieved 100% treatment success with the minimal safety concern.

Safety and efficacy of short course combination regimens with AmBisome, miltefosine and paromomycin for the treatment of visceral leishmaniasis (VL) in Bangladesh. PLoS Negl Trop Dis 2017; 11:e0005635. [PMID: 28558062 PMCID: PMC5466346 DOI: 10.1371/journal.pntd.0005635] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Revised: 06/09/2017] [Accepted: 05/10/2017] [Indexed: 01/24/2023] Open
Abstract
Background AmBisome therapy for VL has an excellent efficacy and safety profile and has been adopted as a first-line regimen in Bangladesh. Second-line treatment options are limited and should preferably be given in short course combinations in order to prevent the development of resistant strains. Combination regimens including AmBisome, paromomycin and miltefosine have proved to be safe and effective in the treatment of VL in India. In the present study, the safety and efficacy of these same combinations were assessed in field conditions in Bangladesh. Methods The safety and efficacy of three combination regimens: a 5 mg/kg single dose of AmBisome + 7 subsequent days of miltefosine (2.5 mg/kg/day), a 5 mg/kg single dose of AmBisome + 10 subsequent days of paromomycin (15 mg/kg/day) and 10 days of paromomycin (15 mg/kg/day) + miltefosine (2.5 mg/kg/day), were compared with a standard regimen of AmBisome 15 mg/kg given in 5 mg/kg doses on days 1, 3 and 5. This was a phase III open label, individually randomized clinical trial. Patients from 5 to 60 years with uncomplicated primary VL were recruited from the Community Based Medical College Bangladesh (CBMC,B) and the Upazila Health Complexes of Trishal, Bhaluka and Fulbaria (all located in Mymensingh district), and randomly assigned to one of the treatments. The objective was to assess safety and definitive cure at 6 months after treatment. Results 601 patients recruited between July 2010 and September 2013 received either AmBisome monotherapy (n = 158), AmBisome + paromomycin (n = 159), AmBisome + miltefosine (n = 142) or paromomycin + miltefosine (n = 142). At 6 months post- treatment, final cure rates for the intention-to-treat population were 98.1% (95%CI 96.0–100) for AmBisome monotherapy, 99.4% (95%CI 98.2–100) for the AmBisome + paromomycin arm, 94.4% (95%CI 90.6–98.2) for the AmBisome + miltefosine arm, and 97.9% (95%CI 95.5–100) for paromomycin + miltefosine arm. There were 12 serious adverse events in the study in 11 patients that included 3 non-study drug related deaths. There were no relapses or PKDL up to 6 months follow-up. All treatments were well tolerated with no unexpected side effects. Adverse events were most frequent during treatment with miltefosine + paromomycin, three serious adverse events related to the treatment occurred in this arm, all of which resolved. Conclusion None of the combinations were inferior to AmBisome in both the intention-to-treat and per-protocol populations. All the combinations demonstrated excellent overall efficacy, were well tolerated and safe, and could be deployed under field conditions in Bangladesh. The trial was conducted by the International Centre for Diarrhoeal Disease Research (ICDDR,B) and the Shaheed Suhrawardy Medical College (ShSMC), Dhaka, in collaboration with the trial sites and sponsored by the Drugs for Neglected Diseases initiative (DNDi). Trial registration ClinicalTrials.gov NCT01122771 Treatment is one of the key strategies for visceral leishmaniasis control and elimination. Historically a number of monotherapy drugs for VL treatment were used in Bangladesh, including pentavalent antimonials, amphotericin B deoxycholate (AmB), and miltefosine (MF). With the limited number of drugs available, it was necessary to preserve existing drugs and also to develop shorter and safer treatment regimens. At the time the study was initiated, miltefosine monotherapy was a recommended first-line treatment in Bangladesh. The present study aimed to provide safety and efficacy data for three short-course combination regimens including AmBisome, miltefosine and paromomycin when rolled out in field conditions in Bangladesh, and to compare these to AmBisome monotherapy. All combinations proved non-inferior to AmBisome monotherapy and were safe and well tolerated. This study was implemented in field conditions at Upazila level with treatment provided by government doctors, providing further evidence for scaling up new regimens in national program contexts within the public health sector.

Abstract
Worldwide primary angioplasty is a recommended strategy of reperfusion in patient with acute myocardial infarction as because it ensures reperfusion of the infarct-related vessels more than 90% whereas, with thrombolytics it is only 60-70%. This retrospective observational study includes all patients treated with primary angioplasty at United Hospital from Between March 2007 to January 2011. Total 114 consecutive patients with acute myocardial infarction were treated with primary angioplasty included. Those presented beyond 12 hours of onset of chest pain, in cardiogenic shock, resuscitate and intubated before the procedure were excluded from the study. Majority (89%) of the patient were male, age was minimum 30 years and maximum 90 years, 41.5% were diabetics, 58.4% were hypertensive, 43.5% were dyslipidaemic, 17% were smoker, 29.3% with positive family history. Fifty seven percent patients presented with anterior MI , 42 % with inferior MI and 1% with lateral MI. Left anterior descending (LAD) is the most common vessel involved (57%), followed by Right coronary artery (RCA) 31%, Left circumflex artery (LCX) 8 %, Ramus 1.3% and Graft vessel 2.7%. Our door to balloon time was minimum 23 min, maximum 184 min. We used drug eluting stents for most of the patients, GP IIb- IIIa receptor blockers used in 50% cases and thrombus suction device were used when indicated. We faced complications like arrhythmias in 24%, hypotension in18%, no flow or slow flow in 45%, cardiac arrest in 3% and coronary perforation in 1%. Our overall survival was 97.9%. Primary angioplasty is an emerging area in context of our country. Many of the new centers start this novel strategy which helps to save many lives Primary angioplasty is feasible and safe method of reperfusion in patient with acute myocardial infarction in our center. With the help of our initial experience we can perform PAMI with confidence to those who can afford and who need most.

Abstract
Identifying noninvasive biomarkers of kidney disease is valuable for diagnostic and therapeutic purposes. Hypoxia inducible factor 1 (HIF-1) expression is known to be elevated in the kidneys in several renal disease pathologies. We hypothesized that the urinary HIF-1a mRNA level may be a suitable biomarker for expression of this protein in chronic kidney disease (CKD). We compared HIF-1a mRNA levels from urine pellets of CKD and healthy subjects. To ensure that urinary HIF-1a mRNA is of kidney origin, we examined colocalization of HIF-1a mRNA with two kidney specific markers in urine cells. We found that HIF-1a mRNA is readily quantifiable in urine pellets and its expression was significantly higher in CKD patients compared with healthy adults. We also showed that the urinary HIF-1a mRNA comes primarily from cells of renal origin. Our data suggest that urinary HIF-1a mRNA is a potential biomarker in CKD and can be noninvasively assessed in patients.

Abstract
The risk factor profiles, management and outcome have significant difference between stroke subsets. Aim of this study was to investigate the risk for the two most common subtypes of stroke in Bangladeshi population. Seventy cases of hemorrhagic stroke (HS) and 105 cases of confirmed ischemic stroke (IS) were recruited from the Shaheed Suhrawardy Medical College Hospital (ShSMCH) and Dhaka Medical College Hospital between January-June 2011. Total 171 age, sex matched controls were selected from the hospitalized patients with history of no stroke ever. Average hemorrhagic stroke patients (60.4±12.3 years) were younger than both ischemic strokes (63.5±13 years). Family history of premature cardiovascular death was found more in HS patients (p=0.001). Multivariate logistic regression showed, in IS model less fruit consumption (OR 4.6), table salt intake (OR 8.15), psychosocial stress (OR 3.5), abnormal ECG (OR 3.6) and Increased WHR (OR 6.9) appeared as significant predictors adjusted for all potential candidate confounders. In HS model less fruit consumption (OR 5.0), table salt intake (OR 9.9), Stress (OR 4.1), family history of cardiovascular disease (CVD) death (OR 11.3), hypertension (OR 43), aspirin intake (OR 4.5) and increased WHR (OR 3.7) remained as significant predictors.

Abstract
Scaling of Si-based nanoelectronics has reached the regime where device function is affected not only by the presence of individual dopants, but also by their positions in the crystal. Determination of the precise dopant location is an unsolved problem in applications from channel doping in ultrascaled transistors to quantum information processing. Here, we establish a metrology combining low-temperature scanning tunnelling microscopy (STM) imaging and a comprehensive quantum treatment of the dopant-STM system to pinpoint the exact coordinates of the dopant in the Si crystal. The technique is underpinned by the observation that STM images contain atomic-sized features in ordered patterns that are highly sensitive to the STM tip orbital and the absolute dopant lattice site. The demonstrated ability to determine the locations of P and As dopants to 5 nm depths will provide critical information for the design and optimization of nanoscale devices for classical and quantum computing applications.

Abstract
In quantum simulation, many-body phenomena are probed in controllable quantum systems. Recently, simulation of Bose-Hubbard Hamiltonians using cold atoms revealed previously hidden local correlations. However, fermionic many-body Hubbard phenomena such as unconventional superconductivity and spin liquids are more difficult to simulate using cold atoms. To date the required single-site measurements and cooling remain problematic, while only ensemble measurements have been achieved. Here we simulate a two-site Hubbard Hamiltonian at low effective temperatures with single-site resolution using subsurface dopants in silicon. We measure quasi-particle tunnelling maps of spin-resolved states with atomic resolution, finding interference processes from which the entanglement entropy and Hubbard interactions are quantified. Entanglement, determined by spin and orbital degrees of freedom, increases with increasing valence bond length. We find separation-tunable Hubbard interaction strengths that are suitable for simulating strongly correlated phenomena in larger arrays of dopants, establishing dopants as a platform for quantum simulation of the Hubbard model.

Abstract
IntroductionThere is strong association between depression and mortality rates among patients with CHF. Despite the massive burden of cardiac disease as well as that of depression in Pakistan, there is limited data regarding the prevalence of depression in patients suffering from CHF. The aim of this study was to assess prevalence of depression in patients with CHF and to compare the health related quality of life of depressed and non-depressed patients with CHF.MethodsA total of 1009 patients diagnosed with CHF were recruited from different public hospitals in Karachi, Pakistan. Depression was assessed at baseline using the Beck Depression Inventory (BDI) and health related quality of life was assessed using Euro Qol (EQ-5D).ResultsOf the 1009 participants recruited to the study, 66.4% (n = 670) met the threshold for depression using the BDI measure. Of the depressed patients, 66.7% (n = 447) were male. Preliminary results indicate that participants who were depressed at baseline had poorer health related quality of life on EQ-5D measures as compared to those who were non-depressed (mean EQ-5D descriptive score 10.45 in depressed patients vs 7.37 in non-depressed patients and mean EQ-5D visual scale score 35.09 in depressed patients vs 52.19 in non-depressed patients).ConclusionConsidering the high prevalence of depression and its serious negative impact on quality of life of patients suffering from chronic physical illness, it is important to design and test culturally adapted psychosocial interventions to reduce depression and improve quality of life for these patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.
