CO-INTEGRATION ANALYSIS OF REMITTANCES, EXPORTS, AND GDP IN BANGLADESH: IMPLICATIONS FOR ECONOMIC DEVELOPMENT AND UNEMPLOYMENT REDUCTION

Remittances and exports are significant sources of foreign exchange earnings for developing nations. This study explores the relationship between remittances, exports, and economic development in Bangladesh. Using the Johansen co-integration approach, the study finds evidence of co-integration among the variables. The results also show that remittances have a significant positive effect on the gross domestic product (GDP) of Bangladesh, while exports do not have a direct impact on GDP. Furthermore, the Granger causality test reveals that there is no significant and positive relationship between remittances and exports. The study suggests that remittances play a vital role in the economic development of Bangladesh by creating employment opportunities, increasing the level of reserves amount, making payments on imports, balancing the balance of payments, and developing other socio-economic aspects. This is especially important in a country where unemployment is a significant issue, and every day the rate of unemployment is increasing. Therefore, policymakers should take into consideration the potential risks and benefits of migration and remittances and adopt appropriate policies to mitigate any negative impacts. Overall, this study contributes to the literature on the impact of remittances and exports on economic development and provides important policy implications for reducing unemployment in Bangladesh.  JEL: F02; F14; F24  Article visualizations

Toxicity outcome of concurrent teletherapy and brachytherapy compared with teletherapy followed by brachytherapy in locally advanced carcinoma cervix

Background: Teletherapy and intracavitary brachytherapy are definitive treatment modalities for stages IIB to IVA cervical carcinoma. Globally, it is the second most common cancer among female. Majority of patients attend the hospital with locally advanced stage due to less screening facility and social stigma.Methods: This quasi-experimental study was conducted from January 2019 to June 2020 with a total of 76 patients. The patients were equally divided into two groups: A and B after obtaining their informed written consent.Results: Final follow up was given after completion of treatment at 24 weeks. Patients in both groups developed grade 1 gastrointestinal and genitourinary toxicities (10.5% versus 13.1%, 13.1% versus 15.7% in group A and B respectively). Two patients in group A and three patients in group B developed grade 2 gastrointestinal toxicities. In genitourinary toxicities, grade 2 toxicities were observed in two patients of group A and four patients of group B, (p>0.05). None developed grade 3 and 4 gastrointestinal and genitourinary toxicities. There were no statistically significant variations in treatment related toxicities between the two groups.Conclusions: Both gastrointestinal, genitourinary toxicities were comparable between two groups. The toxicities were acceptable and well tolerated.

Comparison of dosimetric parameters between intensity modulated and three-dimensional conformal radiotherapy planning for adjuvant therapy of gastric cancer

Background: Adjuvant chemoradiotherapy is the standard treatment for gastric carcinoma, but the optimal radiation modality remains uncertain. This study aimed to compare intensity-modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) in terms of dosimetry for adjuvant gastric cancer treatment. Methods: 21 patients with stage IIB-IIIC gastric cancer, treated between January and June 2021, underwent surgery followed by adjuvant chemoradiation with both IMRT and 3D-CRT plans. Dosimetric parameters were calculated for the planned target volume (PTV) and organs at risk (OAR). Results: Both IMRT and 3D-CRT provided comparable PTV coverage. However, IMRT significantly improved kidney sparing, reducing the mean V20 value by 23% (p=0.01) for the right kidney and 26% (p=0.02) for the left kidney compared to 3D-CRT. IMRT also decreased the mean irradiated volume for both kidneys and the liver, as well as the V30 value for the liver, although these differences were not statistically significant. The dosimetric parameters for the spinal cord were comparable between IMRT and 3D-CRT plans. Conclusions: IMRT demonstrated better kidney sparing compared to 3D-CRT in adjuvant radiotherapy for gastric cancer, while PTV coverage was similar. Long-term follow-up is necessary to assess clinical outcomes and local recurrence rates for both treatment plans

Thermal performance of gasifier cooking stoves: A systematic literature review [version 2; peer review: 2 approved]

A systematic literature review was conducted to summarize the overall thermal performance of different gasified cooking stoves from the available literature. For this purpose, available studies from the last 14 years (2008 to 2022) were searched using different search strings. After screening, a total of 28 articles were selected for this literature review. Scopus, Google Scholar, and Web of Science databases were used as search strings by applying “Gasifier cooking stove” AND “producer gas cooking stove” AND “thermal performance” keywords. This review uncovers different gasified cooking stoves, cooking fuels, and fabrication materials besides overall thermal performances. The result shows that the overall thermal performance of different gasified cooking stoves was 5.88% to 91% depending on the design and burning fuels. The premixed producer gas burner with a swirl vane stove provided the highest overall thermal performance range, which was 84% to 91%, and the updraft gasified stove provided the lowest performance, which was 5.88% to 8.79%. The result also demonstrates that the wood pellets cooking fuel provided the highest thermal performance and corn straw briquette fuel provided the lowest for gasified cooking stoves. The overall thermal performance of wood pellets was 38.5% and corn straw briquette was 10.86%

Knowledge of cervical cancer and HPV vaccine in Bangladeshi women: a population based, cross-sectional study

Abstract Background The objective of this study was to assess the level of knowledge of cervical cancer among Bangladeshi women and to assess their willingness to receive the human papillomavirus (HPV) vaccine. Methods A population-based, cross-sectional survey was conducted from July to December 2011 in one urban and one rural area of Bangladesh. A total of 2037 ever-married women, aged 14 to 64 years, were interviewed using a structured questionnaire. Data on socio-demographic characteristics and knowledge of cervical cancer were collected. Willingness to receive the HPV vaccine was assessed. Univariate analyses were completed using quantitative data collected. Multivariable logistic regression models were developed to identify factors associated with having heard of cervical cancer and the HPV vaccine. Results The majority of study participants reported to have heard of cervical cancer (urban: 89.7%, rural 93.4%; P = 0.003). The odds of having heard of cervical cancer were significantly higher in urban women aged 35–44 years (aOR: 2.92 (1.34–6.33) and rural women aged 25–34 years (aOR: 2.90 (1.24–6.73) compared to those aged less than 24 years. Very few women reported to have detailed knowledge on risk factors (urban:9.1%, rural: 8.8%) and prevention (urban: 6.4%, rural: 4.4%) of cervical cancer. In our sample, one in five urban women and one in twenty rural women heard about a vaccine that can prevent cervical cancer. Among urban women, secondary education or higher (aOR: 3.48, 95% CI: 1.67–7.25), age of 20 years and above at marriage (aOR: 2.83, 95% CI: 1.61–5.00), and high socioeconomic status (aOR: 2.25, 95% CI: 1.28–3.95) were factors associated with having heard of the HPV vaccine. Willingness to receive the HPV vaccine among study participants either for themselves (urban: 93.9%, rural: 99.4%) or for their daughters (urban: 91.8%, rural: 99.2%) was high. Conclusions Detailed knowledge of cervical cancer among Bangladeshi women was found to be poor. Education on cervical cancer must include information on symptoms, risk factors, and preventive methods. Despite poor knowledge, the study population was willing to receive the HPV vaccine

Live bird market in Bangladesh: regulatory systems and operations

Objective: In developing countries, such as Bangladesh, the live bird market (LBM) is a vital location for the trading of live poultry. The study was carried out in nine LBMs located around Bangladesh to ascertain the present regulations and procedures governing their operation. Additionally, the responsibilities and levels of engagement of the stakeholders were determined. Materials and Methods: The data were gathered through the use of a semi-structured interview guide. Thematic analysis was used to code the interview transcripts iteratively. Results: The findings indicated that the government was directly and indirectly involved in the leasing process of the markets. A market in this country is divided into numerous sectors, includ- ing LBM, fish market, vegetable market, and grocery stores. A market's hygienic condition is highly dependent on market authority's decisions. In some markets, market officials conducted routine sanitary inspections. Veterinarians played a little role in the inspection procedure. Conclusion: There is no adequate, functional monitoring system to ensure that LBMs adhere to cleanliness and adequate and functional biosecurity. Biosecurity enhancements, effective clean- ing programs, and regular monitoring by relevant authorities are critical for LBMs in Bangladesh

Association of clinico-epidemiological features with locally advanced stage of cervical cancer patients presenting at Bangabandhu Sheikh Mujib Medical University, Bangladesh

Cervical cancer is one of the most prevalent gynecological cancers in women in Bangladesh. The objective of this study was to assess the clincoepidemiological association with the histology of locally advanced cervical cancer. We have done this observational study in the department of Clinical Oncology at Bangabandhu Sheikh Mujib Medical University from July to December 2019. Sixty-six biopsy-proven locally advanced (stage IIB to IVA) squamous cell carcinoma of uterine cervix were included in this study. The mean age of patients at diagnosis was 48.5 (±8.6) years. Commonly observed epidemiological characteristics of locally advanced carcinoma cervix were illiteracy (46.9%), oral contraceptive use (62.1%), multi para (78.7%) and early marriage (74.2%). Most frequent clinical presentation was post-coital bleeding (37.87%). Most patients presented in stage IIB (65.1%). The association of the stages of the disease with age, parity, oral contraceptive use, age at marriage and clinical presentation were statistically nonsignificant, whereas illiteracy was statistically significant. Most women had poor awareness regarding their need for routine check-up and screening as indicated by the late medical care seeking. Social stigma might have played some role. Relevant programmes should create awareness among women, especially those with socioeconomic deprivation. BSMMU J 2022; 15(3): 175-17

Effect of early tranexamic acid administration on mortality, hysterectomy, and other morbidities in women with post-partum haemorrhage (WOMAN): an international, randomised, double-blind, placebo-controlled trial

Background Post-partum haemorrhage is the leading cause of maternal death worldwide. Early administration of tranexamic acid reduces deaths due to bleeding in trauma patients. We aimed to assess the effects of early administration of tranexamic acid on death, hysterectomy, and other relevant outcomes in women with post-partum haemorrhage. Methods In this randomised, double-blind, placebo-controlled trial, we recruited women aged 16 years and older with a clinical diagnosis of post-partum haemorrhage after a vaginal birth or caesarean section from 193 hospitals in 21 countries. We randomly assigned women to receive either 1 g intravenous tranexamic acid or matching placebo in addition to usual care. If bleeding continued after 30 min, or stopped and restarted within 24 h of the first dose, a second dose of 1 g of tranexamic acid or placebo could be given. Patients were assigned by selection of a numbered treatment pack from a box containing eight numbered packs that were identical apart from the pack number. Participants, care givers, and those assessing outcomes were masked to allocation. We originally planned to enrol 15 000 women with a composite primary endpoint of death from all-causes or hysterectomy within 42 days of giving birth. However, during the trial it became apparent that the decision to conduct a hysterectomy was often made at the same time as randomisation. Although tranexamic acid could influence the risk of death in these cases, it could not affect the risk of hysterectomy. We therefore increased the sample size from 15 000 to 20 000 women in order to estimate the effect of tranexamic acid on the risk of death from post-partum haemorrhage. All analyses were done on an intention-to-treat basis. This trial is registered with ISRCTN76912190 (Dec 8, 2008); ClinicalTrials.gov, number NCT00872469; and PACTR201007000192283. Findings Between March, 2010, and April, 2016, 20 060 women were enrolled and randomly assigned to receive tranexamic acid (n=10 051) or placebo (n=10 009), of whom 10 036 and 9985, respectively, were included in the analysis. Death due to bleeding was significantly reduced in women given tranexamic acid (155 [1·5%] of 10 036 patients vs 191 [1·9%] of 9985 in the placebo group, risk ratio [RR] 0·81, 95% CI 0·65–1·00; p=0·045), especially in women given treatment within 3 h of giving birth (89 [1·2%] in the tranexamic acid group vs 127 [1·7%] in the placebo group, RR 0·69, 95% CI 0·52–0·91; p=0·008). All other causes of death did not differ significantly by group. Hysterectomy was not reduced with tranexamic acid (358 [3·6%] patients in the tranexamic acid group vs 351 [3·5%] in the placebo group, RR 1·02, 95% CI 0·88–1·07; p=0·84). The composite primary endpoint of death from all causes or hysterectomy was not reduced with tranexamic acid (534 [5·3%] deaths or hysterectomies in the tranexamic acid group vs 546 [5·5%] in the placebo group, RR 0·97, 95% CI 0·87-1·09; p=0·65). Adverse events (including thromboembolic events) did not differ significantly in the tranexamic acid versus placebo group. Interpretation Tranexamic acid reduces death due to bleeding in women with post-partum haemorrhage with no adverse effects. When used as a treatment for postpartum haemorrhage, tranexamic acid should be given as soon as possible after bleeding onset.
