Climate change may affect human health through multiple and interactive pathways that include safe water scarcity. However, impacts of climate change-induced water scarcity on health and well-being are *** 80% of illnesses in developing countries are attributed to unsafe drinking water and waterborne diseases. In Southwestern Bangladesh, lack of safe drinking water is a severe crisis due to climate change. The study investigated the impacts of climate change on water resources and human health in a coastal area. A questionnaire survey was carried out in two villages of Shymnagar upazila on the southwestern coast to investigate the present status of safe water sources and health care facilities and their impacts on the local community. The results show that the local community believes that climate change is having substantial impacts on freshwater sources and health. More than 70% of the respondents identified diarrhea, dysentery,and skin diseases as the prime waterborne health risks that occur through climate-related safe water scarcity. By synthesizing the ground data, we suggest pathways to health adaptation to climate change effects and safe water scarcitythrough locally available adaptive practices such as the use of pond sand filters, rainwater harvesting, and importing potable water with the active participation of the government,nongovernmental organizations, and communities.

Preparation of Durable Antibacterial Polyester Fabrics by Grafting with the Natural Quaternary Ammonium Compound Betaine

引用

Materials Sciences and Applications 2024年第9期15卷 378-398页

作者： md Shariful Islam md Kamrul Hasan Arifur Rahman Shakhauat Hossen md.anwarul Islam Sachi Xinbo Ding School of Textile Science and Engineering International Silk Institute Zhejiang Sci-Tech University Hangzhou China King Graduate School Monroe College Bronx NY USA

Recently, the textile industry has increasingly advocated for natural resource-based healthcare textiles. This research presents a facile and eco-friendly approach to developing durable antibacterial polyester fabrics. Polyester fabric was first subjected to an alkaline hydrolysis to impart hydroxyl groups on the fiber surface. A natural antibacterial agent, betaine, was then covalently bonded to the hydrolyzed polyester fiber surface through esterification. XPS, Raman, SEM, and Wicking measurements were carried out to verify the esterification reaction. Antibacterial tests confirmed that betaine treatment grafted polyester fabrics revealed a remarkable antibacterial effect with inhibition rates > 99.9% against both E. coli and S. aureus and still remained inhibition rates of up to 91.5% against both bacteria after home washing for 20 cycles. Moreover, the modification significantly increased the capillary effect of polyester fabric but did not cause apparent adverse effects on the fabric’s hand or tensile strength. Overall, this grafting strategy for durable, antibacterial polyester fabric represents a significant practicality in the textile industry.

引用

Advances in Infectious Diseases 2020年第3期10卷 94-100页

作者： md. Reaz Uddin Chowdhury Kazi Shanzida Akter Sahedul Islam Bhuiyan md. Khalilur Rahman Khabir Bimal Chandra Das Muhammad anwarul Kabir Abdul Malek Ukil Medical College Noakhali Bangladesh Dedicated COVID-19 Hospital-Trauma Center Feni Bangladesh Brahmanbaria Medical College Brahmanbaria Bangladesh 250 Bed District Sadar Hospital Feni Bangladesh

Background: Novel corona virus (SARS-Coronavirus-2 SARS-CoV-2) which emerged in China has spread to multiple countries rapidly. Little information is known about delayed viral clearance in mild to moderate COVID-19 pa-tients. As it is highly contagious, health care workers including physicians are high risk of being infected in hospital care. Case Report: A 37 years old Bangladeshi physician working in a paediatric unit of a medical college hos-pital with multiple co-morbidities, hypertension, diagnosed axial spondy-loarthropathy (ankylosing spondylitis) taking disease modifying anti rheu-matic drugs— DMARDs (Salfasalazine) from 2016 till now, chronic persis-tent bronchial asthma on medication developed sore throat, increasing breathlessness and cough admitted to his own hospital on 22 April, 2020. He had a history of contact with a relapse nephrotic syndrome (glomerulone-phritis) patient admitted with severe respiratory distress later confirmed as COVID-19 following RT PCR test on 14 April, 2020. After 3 days of contact with the patient, the physician also developed the symptoms mentioned above. The RT PCR test result of the physician came positive on 18 April, 2020. The physician primarily taken only azithromycin 500 mg once daily along with other regular drugs. On 5, 12 and 18 May, 2020, his sample was taken for re-test and came positive subsequently. After that he started Iver-mectin (0.15 mg/kg) once daily for 3 days and doxycycline 100 mg BD for 7 days. He gave samples again on 27 and 29 May, 2020 which were came nega-tive after 39 days. On full recovery he was discharged from hospital on day 40. We choose the patient because presence of co-morbidities may be asso-ciated with delayed viral clearance and physicians with co-morbidities working in a hospital have high risk of being infected.

Background: Since 2019, the pandemic of Coronavirus disease 2019 (COVID-19) has spread very rapidly in China and Worldwide. COVID-19 is a highly contagious, infectious and rapidly spreading viral disease with an alarming case fatality rate up to 5%. Case Report: In this article, we report a case of 60 years old non diabetic, hypertensive woman infected with COVID-19 who has end stage renal disease (ESRD) on hemodialysis for last 18 months. COVID-19 patients with ESRD need isolation dialysis but most of them cannot be handled properly due to limited hemodialysis machine. With these unavailability and risk, we continue the treatment along with hemodialysis for controlling uraemia and fluid balance. With all effort this patient ended with an uneventful course with clinical improvement, improvement of all laboratory parameters and resolution of radiological findings but follow up RT-PCR cannot done due to changing guideline of discharge criteria of COVID-19 patient in Bangladesh.

Effect of Tillage and Residue Retention on Soil Properties and Crop Yields in Wheat-Mungbean-Rice Crop Rotation under Subtropical Humid Climate

引用

Open Journal of Soil Science 2017年第1期7卷 1-17页

作者： Nazmus Salahin Khairul Alam Abu Taher Mohammad anwarul Islam Mondol Mahammad Shariful Islam md. Harunur Rashid Muhammad Azizal Hoque Soil Science Division Bangladesh Agricultural Research Institute (BARI) Gazipur Bangladesh Land Management Group School of Veterinary and Life Sciences Murdoch University Murdoch Australia On-Farm Research Division BARI Gazipur Bangladesh Department of Agricultural Extension MoA Dhaka Bangladesh

The effects of conservation agriculture (CA) practices on soil properties along with crop yields of rice-based triple cropping systems have not been adequately assessed in Bangladesh. An experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur, Bangladesh from 2009 to 2012 to assess the effects of tillage practices and crop residue retention on soil physical properties, soil organic carbon (SOC) and crop yields in a wheat-mungbean-rice system. Treatments consisted of three tillage practices (MT: minimum tillage;CT: conventional tillage and DT: deep tillage) and eight levels of crop residue management (S0—no residues retention, Sr—retention of 30 cm rice straw, Sm—whole mungbean stover retention, SW—30 cm wheat straw retention, Smr—whole mungbean stover & 30 cm rice straw retention, Srw—30 cm rice & wheat straw retention, Smw—whole mungbean stover & 30 cm wheat straw retention and Swrm—30 cm wheat and rice straw along with whole mungbean stover retention) were applied in split plot design with three replications. Bulk density (BD) and porosity responded positively to MT and increased residue retention of all crops (p > 0.05). Minimum tillage and Swrm also significantly accumulated SOC (p < 0.05;0.38% higher than DT with no residue retention) and retained soil moisture (p < 0.05). Minimum tillage practice performed better in upland crops (p < 0.05;wheat & mungbean yields) and CT outperformed MT in wetland rice crop (p < 0.05). The grain and straw yields of wheat and rice were also influenced by previous crop residue retentions (p < 0.05). The results, therefore, suggested that increased residue retention with minimum tillage practices improved soil properties and yield of upland crops but with deeper tillage practices consistently maintained wetland rice production.

Background: By the dawn of this modern era of science, the prime challenge of physician is cardiovascular disease (CVD). The most important modifiable risk factors of CVDs are unhealthy diet, physical inactivity and tobacco use. The effects of unhealthy diet and physical inactivity include abnormal blood lipid, obesity and hypertension. We tried to evaluate and correlate the pattern of lipid profile in obese and non-obese hypertensive patients. Objectives: This study was conducted at medicine department of Cumilla Medical College Hospital. The principal aim was to evaluate the lipid profile in obese and non-obese adult hypertensive patients. Methodology: During this cross sectional analytical study, a total of 100 adult hypertensive patients were taken by purposive sampling. Among them 50 (group 1) patients were taken those were obese and 50 (group 2) patients taken those were non-obese according to BMI measurement on operational definition. Diagnosis of hypertension would be established with the help of ambulatory BP measurements two occasions few minutes apart. The staging of hypertension was done according to JNC7 Criteria. Morning blood samples were taken after 8 - 12 hours of fasting and lipid profiles were done on authentic laboratories. The laboratory values were interpreted according to the operational definition of dyslipidaemia. The ethical research and review committee approved the study protocol and signed informed consent was obtained from the participants. The statistics was analyzed using the IBM SPSS software of version 19.0. Statistical significance was set at p Results: Among the two groups, there were 56 (56%) males and 44 (44%) females. The mean age of group 1 (46.10 ± 11.09) was compared to that of group 2 (
