The recent performance of Bangladesh is glowing in case of inland fish production. But sustainability of such healthy-looking condition is very much thought-provoking as environmental damage is also noteworthy in Bangladesh. This article examined mainly the relationship between the environmental damage and its impact on fish production in Bangladesh. This paper uses time series data from 1971-2018 on total fish production (FP), emission of Greenhouse gas (GHG) and use of chemical fertilizers (CF) in Bangladesh. Here researchers use emission of GHGs (proxy to air pollution) and total use of chemical fertilizers (proxy to water pollution) as proxy variables to represent environmental damage. Cointegration test shows that there is long run negative relationship between fish production and GHGs emission but positive relationship between fish production and use of chemical fertilizers. Granger Causality test shows that both fish production and use of chemical fertilizer have causality to GHGs emission. Government steps along with public awareness is required to mitigate environmental damage and maintain stable fish production in the long-run.

This is a conference paper. ; Since 2000, Village Education Resource Centre (VERC) and WaterAid Bangladesh (WAB) have in partnership been pioneering a Community Led Total Sanitation Approach (CLTS), leading to an end to open defecation in over 100 villages in Bangladesh and not exclusively reliant on addressing traditional indicators such as latrine coverage and hygiene behaviour change. To explore the process, cost, motivational and sustainability factors which could support a wider application of this approach, a study was initiated through collaboration between Sophie Allan, a Master's student at the London School of Hygiene and Tropical Medicine, and Tawheed Reza Noor of WAB. WAB and VERC then undertook additional research activities including investigation of local government perceptions. Findings highlighted the extremely low cost of the latrines built, the importance placed upon prestige and practical need over health, the self-determined progression of households up the sanitation ladder and the enthusiastic support of local government officials.

Household food security (HFS) affects the quality and adequacy of nutrition and can significantly impact an individual's health. The study aims to examine the association between HFS and maternal quality of life in Punjab. The cross-sectional study was conducted in the northern Indian state of Punjab from January to March 2021 on 384 expectant mothers. The urban health facilities were chosen using the random cluster selection approach from geographical locations in Punjab, India. A well-structured questionnaire was adapted from HFS and health-related quality of life (HR-QoL) that was used to collect the data. Descriptive statistics were used to investigate the socioeconomic status and food security. HFS and HR-QOL relationship was studied using multilinear regression. The results revealed that 43.9% of expectant women experienced food insecurity. Mean (±SD) scores for the domains of 'social performance' (84.4 ± 16.6) and 'role limitation due to physical reasons' (64.5 ± 35.5) were the highest in pregnant women. Quality of life scores for expectant mothers with food insecurity were the lowest. Due to physical reasons, role constraint scored the weakest for pregnant women with food insecurity (64.3 ± 45.5, 69.1 ± 43.2 and 49.3 ± 57.2, respectively, for mild, moderate and severe food insecurity). High-risk pregnant women screened for HFS in their primary prenatal care can increase their diet quality and quantity. Additionally, there is a need for multi-level actions such as policy development, resource allocation and proper amenities to ensure expectant mothers have access to nutritious food.

Introduction: Knee joint is one of the most important joint needed for locomotion but unfortunately it?s commonly affected by degenerative diseases, which ultimately lead to joint replacement surgery. Anthropometric measurements of distal femur will help in appropriate designing of knee joint replacement prosthesis. Methods: In this study eighty adult dry femurs were taken for distal anthropometric measurements in department of anatomy, government medical college Jammu. Bicondylar Width and transverse diameter of femur shaft were measured using vernier caliper. Results: The mean Bicondylar width of 80 femurs studied was 74.96 ? 5.35 millimeters (mms), of which 42 right sided femurs had mean Bicondylar width of 74.98 ? 5.91 mms and in 38 left sided femurs it was 74.94 ? 4.74 mms. The mean transverse shaft diameter of studied femurs was 24.88? 2.07 mms of which right sided femurs had mean transverse diameter of 25.07 ? 2.19 mms and in left sided femurs it was 24.67 ? 1.94 mms. Conclusion: The measurements obtained will help biomedical engineers in designing the knee replacement prosthesis of appropriate size for Indian patients undergoing knee replacement surgeries.

Abstract
Background
The removal of phenol from aqueous solution via photocatalytic degradation has been recognized as an environmentally friendly technique for generating clean water. The composite nanofibers containing PAN polymer, CNT, and TiO2 NPs were successfully prepared via electrospinning method. The prepared photocatalyst is characterized by SEM, XRD, and Raman spectroscopy. Different parameters are studied such as catalyst amount, the effect of pH, phenol concentration, photodegradation mechanism, flow rate, and stability of the composite nanofiber to evaluate the highest efficiency of the photocatalyst.

Results
The composite nanofibers showed the highest photodegradation performance for the removal of phenol using UV light within 7 min. The pH has a major effect on the photodegradation of phenol with its maximum performance being at pH 5.

Conclusions
Given the stability and flexibility of the composite nanofibers, their use in a dynamic filtration is possible and can be even reused after several cycles.

A new strain of coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the coronavirus disease 2019 (COVID-19) pandemic was first detected in the city of Wuhan in Hubei province, China in late December 2019. To date, more than 1 million deaths and nearly 57 million confirmed cases have been recorded across 220 countries due to COVID-19, which is the greatest threat to global public health in our time. Although SARS-CoV-2 is genetically similar to other coronaviruses, i.e., SARS and Middle East respiratory syndrome coronavirus (MERS-CoV), no confirmed therapeutics are yet available against COVID-19, and governments, scientists, and pharmaceutical companies worldwide are working together in search for effective drugs and vaccines. Repurposing of relevant therapies, developing vaccines, and using bioinformatics to identify potential drug targets are strongly in focus to combat COVID-19. This review deals with the pathogenesis of COVID-19 and its clinical symptoms in humans including the most recent updates on candidate drugs and vaccines. Potential drugs (remdesivir, hydroxychloroquine, azithromycin, dexamethasone) and vaccines [mRNA-1273; measles, mumps and rubella (MMR), bacille Calmette-Guérin (BCG)] in human clinical trials are discussed with their composition, dosage, mode of action, and possible release dates according to the trial register of US National Library of Medicines (clinicaltrials.gov), European Union (clinicaltrialsregister.eu), and Chinese Clinical Trial Registry (chictr.org.cn) website. Moreover, recent reports on in silico approaches like molecular docking, molecular dynamics simulations, network-based identification, and homology modeling are included, toward repurposing strategies for the use of already approved drugs against newly emerged pathogens. Limitations of effectiveness, side effects, and safety issues of each approach are also highlighted. This review should be useful for the researchers working to find out an effective strategy for defeating ...

Background Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction. Methods This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index 60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models were used to explore the associations between lockdowns and non-operation. Intervals from diagnosis to surgery were compared across COVID-19 government response index groups. This study was registered at ClinicalTrials.gov, NCT04384926. Findings Of eligible patients awaiting surgery, 2003 (10·0%) of 20 006 did not receive surgery after a median follow-up of 23 weeks (IQR 16–30), all of whom had a COVID-19-related reason given for non-operation. Light restrictions were associated with a 0·6% non-operation rate (26 of 4521), moderate lockdowns with a 5·5% rate (201 of 3646; adjusted hazard ratio [HR] 0·81, 95% CI 0·77–0·84; p<0·0001), and full lockdowns with a 15·0% rate (1775 of 11 827; HR 0·51, 0·50–0·53; p<0·0001). In sensitivity analyses, including adjustment for SARS-CoV-2 case notification rates, moderate lockdowns (HR 0·84, 95% CI 0·80–0·88; p<0·001), and full lockdowns (0·57, 0·54–0·60; p<0·001), remained independently associated with non-operation. Surgery beyond 12 weeks from diagnosis in patients without neoadjuvant therapy increased during lockdowns (374 [9·1%] of 4521 in light restrictions, 317 [10·4%] of 3646 in moderate lockdowns, 2001 [23·8%] of 11 827 in full lockdowns), although there were no differences in resectability rates observed with longer delays. Interpretation Cancer surgery systems worldwide were fragile to lockdowns, with one in seven patients who were in regions with full lockdowns not undergoing planned surgery and experiencing longer preoperative delays. Although short-term oncological outcomes were not compromised in those selected for surgery, delays and non-operations might lead to long-term reductions in survival. During current and future periods of societal restriction, the resilience of elective surgery systems requires strengthening, which might include protected elective surgical pathways and long-term investment in surge capacity for acute care during public health emergencies to protect elective staff and services.
