Special Economic Zone (SEZ) has been one of the main drivers of economic development in many developing countries. One of the success stories of these SEZs is China. The giant country began its SEZs at the beginning of the 1980s and in several years, these SEZs have branched out elsewhere in the country. The ability of these SEZs to attract investors and spur economic growth in neighboring regions leading eventually to overall China’s economic success cannot be separated from the strong commitment of the Chinese government to developing these zones. However, commitment turns out not to be the only factor for the success of SEZ program. The ability to devise strategic plan considering all factors including the socio-cultural and geostrategic variables is also the key to the success. What China has done to develop its SEZs can be an invaluable lesson for Indonesia who aspires to develop its own SEZs in order to spur regional growth.

Published: September 2024

Background: Clinically significant depression is estimated to occur in a significant portion of chronic heart failure (CHF) patients and increases sharply with increase in heart failure severity. However, the frequency and predictors of depression in this group of patients are underreported. This study was designed to assess frequency & predictors of depression in patients of chronic heart failure with reduced ejection fraction (HFrEF).
Methods: This cross-sectional analytical study was performed in the department of Cardiology, Dhaka Medical College Hospital, Dhaka, during the period from October’2018 to Septemeber’2019. One hundred and fifty-two CHF patients with reduced ejection fraction (<40%) either admitted in the department of Cardiology or attended Cardiology OPD, Dhaka Medical College Hospital (DMCH), Dhaka who fulfilled the selection criteria were included into the study. A translated and validated Patient Health Questionnaire (PHQ-9) in Bengali was used to assess depression level in CHF patients in this study. Informed written consent was taken from each patient. Approval for the study was taken from Ethical Review Committee (ERC) of Dhaka Medical College before commencement of the study. After compiling data from all participants, statistical analyses were performed using the Statistical Package for Social Science (SPSS), version 22.0 for windows.
Results: Mean age of the patients was 58.68±9.40 years, ranging from 36 to 75 years. Male predominance was noted (72% vs 28%). Overall, frequency of depression was 56%. Among the depressed patients (n=85), majority (40%) had minimal depression while 27%, 19% and 14% had mild, moderate and severe depression. respectively. Among the different risk factors, DM and sedentary lifestyle were significantly associated with depression (p<0.05). Age >65 years, sedentary lifestyle, and H/O past MI were independently associated with depression among chronic HErEF patients. Widowed patients, diabetes, hospital readmission in last 2 months before study inclusion and NYHA class III/IV were also significantly associated with depression among patients with chronic HFrEF (p<0.05).
Conclusion: More than half of the patients with chronic HFrEF had concurrent depression of varied severity. Proper care of depression along with HF may improve the survival and quality of life of these patients.

Published: September 2024

Background: Hypoalbuminemia is associated with morbidity and mortality in critically ill children and is a well-recognized predictor of general surgical risk. It frequently occurs in patients with congenital heart disease (CHD). Moreover, cardiopulmonary bypass (CPB)-induces an inflammatory response, and the overall surgical stress can affect albumin concentration greatly
Objective: To estimate pre-operative, per-operative and post-operative serum albumin level and to see its influence on immediate outcomes in children with congenital heart disease undergoing cardiac surgery with cardiopulmonary bypass
Methods: This cross-sectional observational study was conducted in Paediatric cardiology department, BSMMU in a view to find out the influence of pre-operative, per-operative and post-operative serum albumin level on immediate outcomes in children with congenital heart disease undergoing cardiac surgery with cardiopulmonary bypass(CPB).The study included total 48 patients of CHD who underwent  CPB. Patients were selected according to inclusion and exclusion criteria.
Result: Mean pre-operative serum albumin was 3.5±0.9 mg/dl whereas per-operative and post-operative serum albumin was 3.3±0.7mg/dl and 3.1±0.7 mg/dl respectively.CPB time was a bit higher in study population (98.4± 29.1min) where as other outcome parameters were within normal range. Duration of hospital stay was 12.2±3.1days. 22 patient (45.8%) developed valvular regurgitation and 6 patient (12.5%) developed pericardial effusion in post-operative echocardiography. Infection was evident by positive blood culture in 7 patients (14.8%). Pre, per and post-operative hypoalbuminaemia was associated with poor outcome after CPB.
Conclusion: Pre, per and post-operative hypoalbuminaemia is a prudent indicator for speculating poor immediate outcome following CPB in children with CHD.

Background: A sedentary lifestyle is associated with increased risk of Coronary Artery Disease (CAD) in women. At least 150min/wk of moderate activity or 75min/wk of vigorous activity or combination is recommended by American Heart Association (AHA) for primary prevention of CAD. The purpose of this study was to assess the physical activity levels of middle aged women and to find out the association of CAD risk factors with physical activity level.
Methods: This cross-sectional analytical study was conducted in Dhaka Medical College Hospital (DMCH) cardiology OPD from May 2019 to April 2020. We interviewed 249 middle aged women (40-55) who attended our OPD during the study period and fulfilled the exclusion and inclusion criteria. Global Physical Activity Questionnaire (GPAQ) was used to assess physical activity level. Blood pressure and BMI was measured. OGTT and fasting lipid profile was done. Subjects with low physical activity was assigned in Group I (n=152), moderate activity in group II (n= 93) and high activity in group III (n= 4). Association between the physical activity levels and presence of CAD risk factors like DM, HTN, dyslipidemia and obesity was evaluated. 
Results: In this study we found that most of the study subjects (61.0%) were in low active group. Overall 70.2% women were menopausal and premature menopause (≤50 years) was found in 47.8% of subjects. Mean age of menopause was 47±3.8; (44-53) years and mean duration of menopause was 3.1±0.5 years. Overall prevalence of DM, HTN, obesity and dyslipidemia was 62.2%, 50.6%, 39.8% and 53.4% accordingly. Women in low active group were having significant higher proportion of DM (52.6%), HTN (65.8%), obesity (57.9%) and dyslipidemia (75.7%) in comparison to moderate active group. Only 4 women were in highly active group and none of the CAD risk factors was present among them.

Background: QRS duration (QRSd) is used to diagnose left bundle branch block (LBBB) and is important for determining cardiac resynchronization therapy eligibility. Others have reported associations of left bundle branch block (LBBB) and interventricular conduction delay with left ventricular (LV) systolic and diastolic dysfunction in patients without clinical HF. Individualized QRSd thresholds may improve diagnosis and intervention strategies. The goal of this study was to assess the relations of QRS duration to echocardiographic left ventricular (LV) dimensions in individuals.
Methods: This was a hospital-based cross-sectional analytical study. A total of 134 purposively selected respondents were included in the study from the patients attending the outpatient or inpatient department of cardiology, Dhaka Medical College Hospital, advised for an echocardiogram. They were divided into two groups depending on their QRS complex duration (Group I≤100 ms and Group II>100 ms). After taking informed written consent, a case record form was filled and Echo measurements were taken following standard procedure with confidentiality.
Results: Among the respondents, the mean age was found 52.68 ± 14.24 years. The majority were male (68%), and around 1/3rd of the respondents were overweight or obese. Males were found to have less QRS duration than females (p<0.001) but there was no difference in age (p=0.814) between the groups. All the risk factors considering obesity, diabetes mellitus, hypertension, family history, smoking status, and dyslipidemia were found in similar proportions in both groups (p>0.05). The study found that the interventricular septum thickness and inferolateral wall thickness were higher among those having a QRS duration of more than 100 ms (Group II), but this difference was not significant (p > 0.05). On the other hand, left ventricular diastolic dimension, systolic dimension, and left ventricular mass were found to be increased significantly (p<0.05) with a reduction in ejection fraction in Group II (p<0.05).
Conclusion: Left ventricular diastolic and systolic dimensions along with left ventricular mass significantly increase according to QRS duration among the patients. Meanwhile, a reduction in ejection fraction was also evident.

Objective: Acute kidney injury (AKI) is a frequent complication after off-pump coronary artery bypass grafting (OPCAB) that complicates recovery, increases treatment cost and mortality. Neutrophil to lymphocyte ratio (NLR) is a systemic inflammatory marker easily derived from complete blood count that has many prognostic potentials. The purpose of this study was to evaluate if there is an association of preoperative NLR with early postoperative AKI following isolated OPCAB. Methods: This cross-sectional study was carried out in the Department of Cardiac Surgery, National Institute of Cardiovascular Diseases (NICVD) on a total of 60 patients aged 31-70 years with no preoperative renal dysfunction undergoing isolated OPCAB between August 2021 and July 2022. Group A included 30 patients with preoperative NLR < 2.65 and Group B included 30 patients with preoperative NLR ≥ ≥≥2.65. Patients were monitored for development of early postoperative AKI according to serum creatinine criteria of Kidney Disease Improving Global Outcomes (KDIGO) 2012 guideline. Results: Two patients from group A and twenty patients from group B developed early postoperative AKI (p < 0.001). Events of AKI were significantly higher in group B patients at all postoperative time points. Multivariate binary logistic regression analysis revealed preoperative NLR ≥ ≥≥2.65 as an independent predictor of early post OPCAB AKI (p = 0.004, OR = 13.746). In receiver operating curve (ROC) analysis area under curve (AUC) was 0.933 (95% CI 0.874-0.992, p < 0.001). It showed 90.91% sensitivity and 73.7% specificity at the pre-set cut off value of NLR at 2.65 where optimal predictability of post-OPCAB AKI occurred with 66.67% positive predictive value, 93.33% negative predictive value and 80% accuracy. Conclusion: Preoperative NLR is significantly associated with early postoperative AKI following isolated OPCAB and therefore it should be incorporated in routine clinical practice for early prediction of AKI and implementing timely preventive strategies.

Published: September 2024

In recent years, a number of new and undescribed anuran species are being discovered at a very fast rate in South and Southeast Asia. With the revelation of more and more species that were previously considered to be some other species, accurate identification of these morphologically cryptic anurans based on morphology alone have become difficult. In this study, we attempted specieslevel identification of 15 frog specimens belonging to the families Dicroglossidae and Microhylidae of Bangladesh by analyzing their 16S and 12S rRNA gene sequences. The collected specimens were successfully identified to be belonging to eight different species, namely Fejervarya dhaka, F. asmati, F. pierri and F. orissaensis; Euphlyctis kalasgramensis and Euphlyctis sp.; Microhyla berdmorei and M. mymensinghensis using BLAST and maximum likelihood analyses. In some cases the frog samples showed morphological resemblance but after molecular analysis they were found to be different and in another case morphologically distant samples were found to be molecularly similar. For example, two of the specimens (ESP 01, ESP 02) turned out to be E. kalasgramensis at molecular analysis, however, did not match with the morphological and morphometric descriptions (specially snout-vent length) described previously. Moreover, a species is suspected to be still undescribed and another species namely M. berdmorei was thought to be absent in Bangladesh which has been recorded in our study. Thus, morphological ambiguity strengthens the urge for molecular analysis for proper identification.

Published: September 2024

The utilization of organic fertilizers is currently on the rise to sustain higher food quality while minimizing environmental pollution. Mulching with organic materials maintains soil physical conditions, crucial for realizing a crop’s genetic yield potential even when all other requirements are met. Hence, a field experiment was conducted to investigate the effects of mustard oil cake (MOC), poultry manure (PM) and vermicompost (V) alone and in combination with mulching (Mu) on growth and yield parameters of Tomato. Significant increases were (p ≤ 0.05) observed in plant height, leaf number, leaf area, stem girth, root length and root girth of tomato plants compared to the control (T1), where no fertilizers were applied. At 90 days after transplantation (DAT), the T9 (V8Mu0) treatment resulted in the highest plant height (142 cm) and the longest root length (25 cm) while the maximum quantity of fresh weight (154.63 g plant-1) for tomato plant was obtained from the treatment T6, which received vermicompost at 4 t ha-1 with mulching. Application of poultry manure at the rate of 8 t ha-1 without mulching (T8) resulted in a significant higher number (14 fruits plant-1) of green tomatoes. Fresh weight of green tomatoes were varied significantly (p ≤ 0.05) among the treatments with the maximum fresh weight obtained from the T₉ (128.97 g plant-1) and the minimum from T₁ (12.73 g plant-1) treatments. Nitrogen, P, K, Ca, Mg and S of green tomatoes varied significantly among the treatments. The utmost P, K, S, Ca and Mg contents (0.72, 6.26, 0.23, 0.54 and 0.31 g kg-1, respectively) of green tomatoes were recorded in the treatment T₆ (V₄Mu). Hence, the utilization of organic fertilizers, either alone or in conjunction with mulching, markedly enhanced the growth and yield of the tested vegetable, offering viable strategies for enhancing the yield potential.

Authors: Hossain Md Salim , Uddin Muhammad Kamal
Published: September 2024

Shift work is an essential feature of industrialized society. Our present study was aimed at investigating the sleep deprivation and sleep quality of the healthcare shift workers in Bangladesh. In investigating so, we took 462 healthcare shift workers from five districts of Bangladesh. Among them 152 were male and 310 were female. The participants ranged from 19 to 65 years of age. We took the participants on the basis of convenience sampling technique from 30 hospitals and medical centers. To collect data we administered Bangla version of Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). Findings of our study revealed that sleep deprivation and shifts were marginally dependent (χ2 = 11.56, p = 0.07). However, sleep quality had been found independent of shifts (χ2 = 4.31, p = 0.12). Shift-wise analyses yielded that sleep deprivation was high (μ = 7.56) and sleep quality was worse (μ = 3.78) in rotating shift workers in comparison to fixed and regular shift workers. Sleep quality was found better outside of metropolitan city (t = -3.258, p<0.01). Findings have been discussed in terms of previous findings and contemporary theories. Recommendations are proposed in the light of our findings in conclusion.

Published: September 2024

The purpose of the present study was to investigate whether selfie taking behavior is beneficial for the mental well-being of young adults and to investigate the difference in psychological issues among people who like to take selfies and those who don’t. Two hundred participants were recruited in this study following convenience sampling technique. The Depression scale, Bangla version of the Self- Esteem scale, and Bangla version of the General Health Questionnaire -12 were used as instruments in this study. This study used t-test and Pearson Product Moment Correlation for analyzing data. Results showed that selfie taking behavior is negatively correlated with depression score which means more selfie taking leads to fewer depressive symptoms. It was also found that people who like to take selfies and post selfies more on social media have shown less depressive symptoms, better self-esteem and less psychological distress than the people who don’t like to take and post selfies. The results can be taken to indicate that people who like to take or post selfies more exhibit a better state of mental well-being and less psychological issues.

The title of the present experiment is Effect of Relaxation Therapy on Stress Management Among Teenagers and Adults. The main purpose of the present experiment was to investigate the impact of relaxation therapy on stress reduction among teenagers and adults in Dhaka city. Utilizing purposive sampling, 30 participants (15 teenagers, 15adults) engaged in a 28-day relaxation program. The Bangla version of Life Stress Questionnaire and other stress management tools were used. Data were collected and analyzed by using ANOVA, t-test, and descriptive analysis. Results indicate a significant reduction in stress levels gradually across both groups for teenagers F for row(relaxation therapy) = 12.480, F for column(among participants) = 9.270 and for adults F for row(relaxation therapy) = 5.519, F for column(among participants) = 1.175 .The study also explores relationships between stress and various variables such as gender ,age, financial condition. Descriptive analysis showed that there was no significant difference between female and male but it reduced slowly for male (from 22.13 to 16.87) and for female (from 23.13 to 18.47) and decreased respectively in both financial groups for higher group (from 22.29 to 18.50) for lower group (from 22.94 to 16.94). The findings underscore the effectiveness of relaxation therapy in managing stress among adults and teenagers in Bangladesh. This study suggests the integration of relaxation therapy into stress management interventions and highlights avenues for future research in this area.

Authors: Chowdhury Md Miraj Kobad , Chowdhury Shibraj , Bari Latiful , Yeasmin Sabina
Published: September 2024

Roselle (Hibiscus sabdariffa L.) flower is a commonly consumed vegetable in Bangladesh and have culinary value to preparation of soup, jelly, and baking. Since previous studies suggested the presence of anthocyanins in roselle calyces, this study was designed to enrich anthocyanins from the calyces of this flower. This study explored that addition of mineral acid during the extraction process further enriched the anthocyanins content of the fresh roselle calyces extract. Also, methanol acidified with 1% (v/v) HCl was found as the best solvent to extract anthocyanins from the calyces resulting 7.621±0.001 mg crude anthocyanins per gram of fresh sample. Anthocyanin extraction decreased if 1% (v/v) HCl was replaced with 10% (w/v) tartaric acid or 10% (v/v) acetic acid. The extracted anthocyanins showed minimal antibacterial activity. A further study will explore the possibility of use these anthocyanins for industrial purposes.
