Aggressive immune response, due to overexpressed proinflammatory molecules, has been characterized in coronavirus disease 2019 (COVID‐19) patients. Some of those mediators have a dual and opposite role on immune systems at play behind differential disease severities. We investigated the expression of some cytokines and chemokines in COVID‐19 patients in Bangladesh. We diagnosed the patients by detecting severe acute respiratory syndrome coronavirus 2 RNA in nasal swab samples by the real‐time RT‐PCR method. Thirty adult patients were preselected based on their disease severities and grouped into mild, moderate, and severe cases. Nine healthy volunteers participated in this study as a control. Relative expression of nine cytokines/chemokine in total leukocytes was semi‐quantified in SYBRgreen‐based real‐time quantitative reverse‐transcriptase polymerase chain reaction. We performed statistical tests on transformed log data using SPSS 24.0. At the onset of symptoms (Day 1), angiotensin‐converting enzyme 2 (ACE2) (p 0.05) were upregulated in all COVID‐19 groups, although the expression levels did not significantly correlate with disease severities. However, expressions of IL‐6, monocyte chemotactic protein‐1, macrophage inflammatory protein‐1α, tumor necrosis factor‐α (TNF‐α), RANTES (regulated upon activation, normal T cell expressed and secreted), and ACE2, on Day 14, were positively correlated with disease severities. Relative viral load at Day 1 showed no significant correlation with cytokine expression but had a significant positive correlation with RANTES and ACE2 expression on Day 14 (p

Tracing the globally circulating severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) phylogenetic clades by high‐throughput sequencing is costly, time‐consuming, and labor‐intensive. We here propose a rapid, simple, and cost‐effective amplification refractory mutation system (ARMS)‐based multiplex reverse‐transcription polymerase chain reaction (PCR) assay to identify six distinct phylogenetic clades: S, L, V, G, GH, and GR. Our multiplex PCR is designed in a mutually exclusive way to identify V–S and G–GH–GR clade variants separately. The pentaplex assay included all five variants and the quadruplex comprised of the triplex variants alongside either V or S clade mutations that created two separate subsets. The procedure was optimized with 0.2–0.6 µM primer concentration, 56–60°C annealing temperature, and 3–5 ng/µl complementary DNA to validate on 24 COVID‐19‐positive samples. Targeted Sanger sequencing further confirmed the presence of the clade‐featured mutations with another set of primers. This multiplex ARMS‐PCR assay is a fast, low‐cost alternative and convenient to discriminate the circulating phylogenetic clades of SARS‐CoV‐2., Highlights Multiplex ARMS‐PCR (amplification refractory mutation system‐polymerase chain reaction) method for genotyping major severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2 clades).Identify the mutated region of circulating phylogenetically SARS‐CoV‐2 clades.PCR conditions were optimized and validated to identify V–S and G–GH–GR clade.

Background and Aim: The use of antibiotic growth promoters (AGPs) in the poultry industry has raised concern because of their potential harm to human health. Emerging evidence suggests that probiotics are a safer substitute, although little research has explored this in Bangladesh. We recently isolated local bacterial strains with probiotic properties. We aimed to determine their impact on the growth, hematobiochemical parameters, and production costs of broiler chicks relative to that of a commercial probiotic (CP) and AGP. Materials and Methods: Day-old male broiler chicks (Cobb 500, n=63) were divided equally into three experimental groups (three replicates per group and seven chicks per replicate). First group was fed a basal diet supplemented with the AGP, ciprofloxacin (CTL group), second group was fed a basal diet supplemented with the CP, Protexin® (CP group), and the third group was fed a basal diet supplemented with our isolated bacterial strains (study probiotic [SP] group) for 36 days. Body weight was recorded daily, and relative growth rate (RGR), feed conversion ratio (FCR), and organ weights and carcass yields were calculated at the study's end. Blood obtained on day 36 was used to determine the number of red blood cell (RBC) and white blood cells (WBCs), hemoglobin (Hb) concentration, packed cell volume, erythrocyte sedimentation rate, as well as levels of serum glucose, total and high-density lipoprotein (HDL) cholesterol, and triglycerides (TGs). Total production costs were estimated by summing the variable and fixed costs. Results: Chicks in both the CP and SP groups experienced significant decreases in blood glucose levels and significant increases in BW, RGR, FCR, levels of RBC and WBC, Hb concentration, and packed cell volume compared with those in the CTL group (p0.05) in levels of total cholesterol, TGs, and HDL in the SP and CP groups when compared to the CTL group. In addition, both CP and SP treatments resulted in significant (p

Probiotics are live microorganisms that, when administered in adequate amounts, confer health benefits to the host. This study was conducted for the isolation of potential lactic acid bacteria (LAB) with probiotic properties from goat milk and yogurt. Several tests were conducted in vitro using the standard procedures for evaluating the inhibitory spectra of LAB against pathogenic bacteria; tolerance to NaCl, bile salt, and phenol; hemolytic, milk coagulation, and bile salt hydrolase activities; gastrointestinal transit tolerance; adhesion properties; and antibiotic susceptibility. Among 40 LAB strains screened according to culture characteristics, five isolates exhibited antagonistic properties. Three were identified as Pediococcus acidilactici, and two were identified as Enterococcus faecium, exploiting 16S rRNA gene sequencing. All the isolates succeeded in the gastrointestinal transit tolerance assay and successively colonized mucosal epithelial cells. Based on the results of these in vitro assays, both P. acidilactici and E. faecium can be considered as potential probiotic candidates.

Raw milk contains wide microbial diversity, composed mainly of lactic acid bacteria (LAB), which are used as probiotics in both human and animal husbandry. We isolated, characterized, and evaluated LAB from indigenous Bangladeshi raw milk to assess probiotic potential, including antagonistic activity (against Escherichia coli O157: H7, Enterococcus faecalis, Salmonella Typhimurium, Salmonella Enteritidis, and Listeria monocytogenes), survivability in simulated gastric juice, tolerance to phenol and bile salts, adhesion to ileum epithelial cells, auto- and co-aggregation, hydrophobicity, α-glucosidase inhibitory activity, and antibiotic susceptibility tests. The 4 most promising LAB strains showed probiotic potential and were identified as Lactobacillus casei, Lactobacillus plantarum (which produced plantaricin EF), Lactobacillus fermentum, and Lactobacillus paracasei. These strains inhibited all pathogens tested at various degrees, and competitively excluded pathogens with viable counts of 3.0 to 6.0 log cfu/mL. Bacteriocin, organic acids, and low-molecular-weight substances were mainly responsible for antimicrobial activity by the LAB strains. All 4 LAB strains were resistant to oxacillin and 3 were resistant to vancomycin and streptomycin, with multiple antibiotic resistance indices >0.2. After further in vivo evaluation, these LAB strains could be considered probiotic candidates with application in the food industry.

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic has been considered with great importance on correct screening procedure. The detection efficiency of recent variants of concern were observed by comparing 5 commercial RT-PCR kits and a SYBR-green method developed and validated in our laboratory. The RNA was extracted from nasopharyngeal samples from suspected COVID-19 patients and RT-PCR assay was performed according to the instruction of the respective manufacturers. The specificity and sensitivity of Maccura kit was 81.8% and 82.5%, A*Star kit was 100% and 75.4%, Da An Gene kit was 100% and 68.4%, Sansure kit was 54.5% and 91.2% and TaqPath kit was 100% and 70.2% respectively. Our in house SYBR-Green method showed a consistent detection result with 90.9% specificity and 91.2% sensitivity. We also found that detection kits targeting more genes showed better accuracy which facilitates less false positive results (

Wastewater based epidemiology (WBE) is an important tool to fight against COVID-19 as it provides insights into the health status of the targeted population from a small single house to a large municipality in a cost-effective, rapid, and non-invasive way. The implementation of wastewater based surveillance (WBS) could reduce the burden on the public health system, management of pandemics, help to make informed decisions, and protect public health. In this study, a house with COVID-19 patients was targeted for monitoring the prevalence of SARS-CoV-2 genetic markers in wastewa-ter samples (WS) with clinical specimens (CS) for a period of 30 days. RT-qPCR technique was employed to target non-structural (ORF1ab) and structural-nucleocapsid (N) protein genes of SARS-CoV-2, according to a validated experimental protocol. Physiological, environmental, and biological parameters were also measured following the American Public Health Association (APHA) standard protocols. SARS-CoV-2 viral shedding in wastewater peaked when the highest number of COVID-19 cases were clinically diagnosed. Throughout the study period, 7450 to 23,000 gene copies/1000 mL were detected, where we identified 47 % (57/120) positive samples from WS and 35 % (128/360) from CS. When the COVID-19 patient number was the lowest (2), the highest CT value (39.4; i.e., lowest copy number) was identified from WS. On the other hand, when the COVID-19 patients were the highest (6), the lowest CT value (25.2 i.e., highest copy numbers) was obtained from WS. An advance signal of increased SARS-CoV-2 viral load from the COVID-19 patient was found in WS earlier than in the CS. Using customized primer sets in a traditional PCR approach, we confirmed that all SARS-CoV-2 variants identified in both CS and WS were Delta variants (B.1.617.2). To our knowledge, this is the first follow-up study to determine a temporal relationship be-tween COVID-19 patients and their discharge of SARS-CoV-2 RNA genetic markers in wastewater from a single house including all family members for clinical sampling from a developing country (Bangladesh), where a proper sewage system is lacking. The salient findings of the study indicate that monitoring the genetic markers of the SARS-CoV-2 virus in wastewater could identify COVID-19 cases, which reduces the burden on the public health system during COVID-19 pandemics.

Severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has evolved into eight fundamental clades with four of these clades (G, GH, GR, and GV) globally prevalent in 2020. To explain plausible epistatic effects of the signature co‐occurring mutations of these circulating clades on viral replication and transmission fitness, we proposed a hypothetical model using in silico approach. Molecular docking and dynamics analyses showed the higher infectiousness of a spike mutant through more favorable binding of G614 with the elastase‐2. RdRp mutation p.P323L significantly increased genome‐wide mutations (p, Highlights Most dominant spike mutation favors elastase‐2 binding.The polymerase mutant (P323L) virus may speed up replication that corresponds to higher mutations.ORF3a viroporin substitution (Q57H) decreases ion permeability.N protein mutation (RG203‐204KR) can increase nucleocapsid stability and help evade immunity.Co‐occurring mutations might modulate viral replication and transmission fitness through epistasis.

Background: Bangladesh introduced ChAdOx1 nCoV-19 since February, 2021 and in six months, only a small population (12.8%) received either one or two dose of vaccination like other low-income countries. The COVID-19 infections were continued to roll all over the places although the information on genomic variations of SARS-CoV-2 between both immunized and unimmunized group was unavailable. The objective of this study was to compare the proportion of immune escaping variants between those groups. Methods: A total of 4718 nasopharygeal samples were collected from March 1 until April 15, 2021, of which, 834 (18%) were SARS-CoV-2 positive. The minimum sample size was calculated as 108 who were randomly selected for telephone interview and provided consent. The prevalence of SARS-CoV-2 variants and disease severity among both immunized and unimmunized groups was measured. A total of 63 spike protein sequences and 14 whole-genome sequences were performed from both groups and phylogenetic reconstruction and mutation analysis were compared. Results: A total of 40 respondents (37%, N = 108) received single-dose and 2 (2%) received both doses of ChAdOx1 nCoV-19 vaccine, which significantly reduce dry cough, loss of appetite and difficulties in breathing compared to none. There was no significant difference in hospitalization, duration of hospitalization or reduction of other symptoms like running nose, muscle pain, shortness of breathing or generalized weakness between immunized and unimmunized groups. Spike protein sequence assumed 21 (87.5%) B.1.351, one B.1.526 and two 20B variants in immunized group compared to 27 (69%) B.1.351, 5 (13%) B.1.1.7, 4 (10%) 20B, 2 B.1.526 and one B.1.427 variant in unimmunized group. Whole genome sequence analysis of 14 cases identified seven B.1.351 Beta V2, three B.1.1.7 Alpha V1, one B.1.526 Eta and the rest three 20B variants. Conclusion: Our study observed that ChAdOx1 could not prevent the new infection or severe COVID-19 disease outcome with single dose while the infections were mostly caused by B.1.351 variants in Bangladesh.

In the aquatic environment, microorganisms are predominantly organized as biofilms. Biofilms are formed by the aggregation of microbial cells and are surrounded by a matrix of extracellular polymeric substances (EPS) secreted by the microbial cells. Biofilms are attached to various surfaces, such as the living tissues, indwelling medical devices, and piping of the industrial potable water system. Biofilms formed from a single species has been extensively studied. However, there is an increased research focus on multispecies biofilms in recent years. It is important to assess the microbial mechanisms underlying the regulation of multispecies biofilm formation to determine the drinking water microbial composition. These mechanisms contribute to the predominance of the best-adapted species in an aquatic environment. This review focuses on the interactions in the multispecies biofilms, such as coaggregation, co-metabolism, cross-species protection, jamming of quorum sensing, lateral gene transfer, synergism, and antagonism. Further, this review explores the dynamics and the factors favoring biofilm formation and pathogen transmission within the drinking water distribution systems. The understanding of the physiology and biodiversity of microbial species in the biofilm may aid in the development of novel biofilm control and drinking water disinfection processes.

AimThe aim of this research is to focus on gaining an insight into the knowledge, attitudes, behavioural practises (KAP), and psychological impact relating to COVID-19 among the people living with spinal cord injury receiving in-patient rehabilitation.MethodsA prospective, cross-sectional survey of people with SCI (N = 207), who were in active in-patient rehabilitation from two tertiary SCI Rehabilitation Centres in Bangladesh. Data were collected via face-to-face interviews, after voluntary consent, using a pretested, language validated questionnaire on Knowledge, Attitude and Behavioural practises (KAP) and the Depression, Anxiety, Stress Scale (DASS-21). Ethical approval and trial registration were obtained prospectively.ResultsA total of 207 people with SCI responded, among which 87% were men and 13% were women, with a mean age of 34.18 ± 12.9 years. Within the sample group, people living with tetraplegia comprised 33.8%, and people living with paraplegia comprised 66.2%. Overall, 63.8% of the participants were diagnosed with an SCI categorised as ASIA-A. Overall, the “knowledge score” was 8.59 ± 2.3 out of 12, “depression” was 11.18 ± 8, “anxiety” was 7.72 ± 5.1, and “stress” was 9.32 ± 6.7 from a total of 21 scores each category. The strong correlation was between knowledge, DASS scores, and age (p < 0.05). In addition, there was a strong correlation between knowledge, gender (p < 0.05) and education (p < 0.01). Binary logistic regression found a stronger association of knowledge and DASS scores with gender, young age, illiteracy (p < 0.01), and rural residence (p < 0.05). A positive relationship was found between depression and anxiety scores (p < 0.01) and a moderate positive relationship was found between depression and stress scores (p < 0.01). A positive attitude was reported by the majority of participants (p < 0.05). In terms of behavioural practises, participants reported both self and caregiver had followed health advice with regard to consulting health professionals (65.7%), implementing isolation (63.8%), taking droplet precaution care (87.4%), and hygiene care (90.3%).ConclusionParticipants in this study reported high levels of knowledge, adoption of positive attitudes, and the practise of positive health advisory behaviours related to COVID-19 prevention procedures. However, high levels of depression, anxiety, and stress were also reported. Overall, women and younger participants were more likely to have high KAP, whereas those living in rural areas and with literacy challenges were less likely to report high knowledge scores.

TaqMan probe-based commercial real-time (RT) PCR kits are expensive but most frequently used in COVID-19 diagnosis. The unprecedented scale of SARS-CoV-2 infections needs to meet the challenge of testing more persons at a reasonable cost. This study developed a simple and cost-effective alternative diagnostic method based on melting curve analysis of SYBR green multiplex assay targeting two virus-specific genes along with a host-specific internal control. A total of 180 randomly selected samples portioning into two subsets based on crude and high-quality RNA extraction were used to compare this assay with a nationwide available commercial kit (Sansure Biotech Inc., (Hunan, China)), so that we could analyze the variation and validity of this in-house developed method. Our customized-designed primers can specifically detect the viral RNA likewise Sansure. We separately optimized SYBR Green RT-PCR reaction of N, E, S, and RdRp genes based on singleplex melting curve analysis at the initial stage. After several rounds of optimization on multiplex assays of different primer combinations, the optimized method finally targeted N and E genes of the SARS-CoV-2 virus, together with the β-actin gene of the host as an internal control. Comparing with the Sansure commercial kit, our proposed assay provided up to 97% specificity and 93% sensitivity. The cost of each sample processing ranged between ~2 and ~6 USD depending on the purification level of extracted RNA template. Overall, this one-step and one-tube method can revolutionize the COVID-19 diagnosis in low-income countries.

Aggressive immune response, due to over-expressed pro-inflammatory molecules, had been characterized in COVID-19 patients. Some of those mediators have a dual and opposite role on immune-systems to play behind differential disease severities. We investigated the expression of some cytokines and chemokines in COVID-19 patients in Bangladesh. We diagnosed the patients by detecting SARS-CoV-2 RNA in nasal swab samples by the real-time RT-PCR method. Thirty adult patients were preselected based on their disease severities and grouped into mild, moderate, and severe cases. Nine healthy volunteers participated in this study as control. Relative expression of nine cytokines/chemokine in total leukocytes was semi-quantified in SYBRgreen-based qRT-PCR. We performed statistical tests on transformed log data using SPSS 24.0. At the onset of symptoms (day-1), ACE2 (P < 0.05) and IL-6 (P > 0.05) were up-regulated in all COVID-19 groups, although expression levels did not significantly correlate with disease severities. However, expression of IL-6, MCP-1, MIP-1α, TNF-α, RANTES, and ACE2, on day-14, were positively correlated with disease severities. Relative viral load at day-1 showed no significant correlation with cytokine expression but had a significant positive correlation with RANTES and ACE2 expression on day-14 (P < 0.05). Male patients had a higher level of IL-6 than female patients on day-1 (P < 0.05). All COVID-19 patients showed up-regulated cytokines and chemokines on the day-14 compared to day-1 except TNF-α. Female patients had higher expression of ACE2 and IL-12 on day-14. Up-regulated cytokines/chemokines at the convalescent stage, especially IL-6, may target anti-cytokine therapy in post-COVID-19 patients’ management.

This study aims to investigate coping strategies used by Bangladeshi citizens during the COVID-19 pandemic.DesignProspective, cross-sectional survey of adults (N=2001) living in Bangladesh.MethodsParticipants were interviewed for socio-demographic data and completed the Bengali translated Brief-COPE Inventory. Statistical data analysis was conducted using SPSS (Version 20).ResultsParticipants (N=2001), aged 18 to 86 years, were recruited from eight administrative divisions within Bangladesh (mean age 31.85±14.2 years). Male to female participant ratio was 53.4% (n=1074) to 46.6% (n=927). Higher scores were reported for approach coping styles (29.83±8.9), with lower scores reported for avoidant coping styles (20.83 ± 6.05). Humor coping scores were reported at 2.68±1.3 and religion coping scores at 5.64±1.8. Both men and women showed similar coping styles. Multivariate analysis found a significant relationship between male gender and both humor and avoidant coping (p religion and approach coping (p approach coping (p ConclusionParticipants in this study coped with the COVID-19 pandemic by utilizing a combination of coping strategies. Factor 1 revealed both avoidant and approach coping strategies and Factor 2 revealed a combination of humor and avoidant coping strategies. Overall, a higher utilization of approach coping strategies was reported, which has previously been associated with better physical and mental health outcomes. Religion was found to be a coping strategy for all participants. Future research may focus on understanding resilience in vulnerable populations, including people with disability or with migrant or refugee status in Bangladesh.

Executive summary: The first confirmed case of COVID 19 in Bangladesh was on 8th March 2020, then it subsequently rises and makes the government worried as well as for mass people of the country. Within 9th March it reaches 100 and exceeded 200 cases within next two days. Almost every country taken therapeutic and nontherapeutic measures to control the devastating situation of SARS-CoV where in Bangladesh there is an ongoing debate whether the measures have been adopted adequately or efficiently. It seems government did not impose any strict rules and the mass people also seem not too serious to maintain just a simple rule of wearing a Musk, which seems fancy and impractical to them. However, the consequences of the impact of SARS CoVwas frustrating, until today confirmed case was 371631, death case 5405, recovered 284833 and in Isolation 81393 (evident from corona.gov.bd).Developed countries investing a lot in research to discover the vaccine that can fight SARS CoV. Health care professionals with adequate training act as frontline fighters for SARS-CoV where all over the globe Rehabilitation professionals act as crucial health care providers for post-COVID patients. For instance, our research has four phases where phase one is completed and phase two is under process. For now, we aimed to complete our phase three and four. Phase Three aim: Identify the Functioning, disability, and other indicators of COVID-19 positive patients after recovery. and Phase four aim: evaluate the impact of physiotherapy and rehabilitation among the recovered COVID-19 patients.

BackgroundThe mortality of COVID-19 disease is very high among males or elderly or individuals having comorbidities with obesity, cardiovascular diseases, lung infections, hypertension, and/or diabetes. Our study characterizes SARS-CoV-2 infected patients’ metagenomic features with or without type 2 diabetes to identify the microbial interactions associated with its fatal consequences.MethodThis study compared the baseline nasopharyngeal microbiome of SARS-CoV-2 infected diabetic and non-diabetic patients with controls adjusted with age and gender. The mNGS were performed using Ion GeneStudio S5 Series and the data were analyzed by the Vegan-package in R.ResultsAll three groups possessed significant bacterial diversity and dissimilarity indexes (p0.6, pConclusionThe dysbiosis of the bacterial community might be linked with severe consequences of COVID-19 infected diabetic patients, although few probiotic strains inhibited numerous pathogens in the same pathological niches. This study suggested that the promotion of normal-flora and probiotics through dietary changes and reduction of excessive pro-inflammatory states by preventing pathogenic environment might lead to a better outcome for those co-morbid patients.

Background: A Delphi-Based Consensus Statement: Recommendation for Physiotherapy Management and Rehabilitation of people living with Long COVID in Bangladesh Background: Covid-19 is a new and deadly virus with global consequences with special vulnerabilities in Bangladesh. The World Health Organization confirmed 22,451,122,614 cases and 4,627,540 deaths, worldwide (13th September 2021). In the United Kingdom, 1.5% of the estimated population of 970,000, suffers from Long COVID. Physiotherapy plays a vital role both in decreasing the number of deaths during the acute stage and improving function for patients across the spectrum of severity in the acute, sub-acute, and long-term context. Objectives: This Delphi-Based Consensus, provides recommendations for physiotherapy management and rehabilitation of people living with Long COVID. It includes recommendations for physiotherapy management for acute and subacute respiratory complications, a specific prescriptive exercise guideline for fatigue and musculoskeletal dysfunction and for improving psychological outcomes through combination of both counseling and rehabilitation. Methods: A team of 8 national and 6 international experts working in different disciplines were provided with studies on physiotherapy interventions in Long COVID-19 and were asked to provide treatment opinions based on the current literature for musculoskeletal, neurorehabilitation, respiratory, cardiac and psychological health domains. Statements were ranked and presented with individual opinions measured on a 10-point Likert Scale. The mean scores for each intervention were calculated and a manuscript with recommended physiotherapy interventions was prepared based on currently available evidence as presented and agreed upon by expert consensus. Findings: Experts recommended the following interventions based on mean agreement scores: diaphragmatic breathing (Mean = 7.5), thoracic expansion (with shoulder elevation) (Mean =8.5) and expiratory muscle training (Mean=6.3) for respiratory rehabilitation. Mild to moderate graded exercise (Mean= 7.7) was suggested for recovery from fatigue and McKenzie directional preference exercises for low back pain (Mean= 8.6), neck pain (Mean =7.9) and knee pain (Mean =8.3). Additionally, communicative and educative strategies were recommended for the rehabilitation of COVID-19. Conclusion: This consensus is structured according to the expert opinions of medical and rehabilitation professionals and based on current literature to recommend a series of rehabilitation interventions for physiotherapy professionals to manage Long COVID cases. Funding: This research has not been funded by any other external organization nor received any grants from commercial or not-for-profit organizations. Declaration of Interests: None declared. Ethics Approval Statement: Ethical permission was obtained from the Centre for the Rehabilitation of the Paralysed (CRP) ethics committee. The reference number CRP-R&E-0401-337.

Study DesignA prospective cross-sectional survey.ObjectiveThe study aimed to examine the Knowledge, Attitudes, and Practices (KAP) of people living with Spinal cord injury (SCI) towards COVID-19 and their psychological status during in-patient rehabilitation in Bangladesh.SettingThe Centre for the Rehabilitation of the Paralyzed (CRP) and the National Institute of Traumatology and Orthopedic Rehabilitation (NITOR), two tertiary level hospitals in Dhaka, Bangladesh.MethodsFrom July to September 2020, a prospective, cross-sectional survey of SCI subjects, 13-78 years of age, carried out in two SCI rehab centers in Bangladesh. Data has been collected by face to face interview through a pretested, and language validated questionnaire on KAP and Depression, Anxiety, Stress (DASS). Ethical approval and trial registration obtained prospectively. As all the patients were previously living with Spinal cord injury (SCI), therefore, all the patients admitted/ attend SCI rehab centers were considered as SCI positive samples.ResultsA total of 207 people with SCI responded, 87%were male, and 13% were female with mean age34.18±12.9 years. 33.8% was tetraplegic and 66.2% was paraplegic and 63.8% of them were diagnosed ASIA-A, with motor score 45.38±19.5, sensory score 97.2±52, SpO2 95.07±3.3, and Vo2max 35.7±3.7mL/kg/min. 178 people had at least one health issue. Overall knowledge score was 8.59±2.3 out of 12, depression 11.18±8, anxiety 7.72±5.1, and stress was 9.32±6.7 from a total of 21 scores each. There was a correlation between Knowledge and DASS with age (POR 6.6, 6.6, .95, 6.6; POR.418, POR3.81, POR.48, Pr.45, Pr.58, PConclusionsDuring in-patient rehabilitation in Bangladesh, the majority of SCI reported that they had communicated with health professionals and practiced behaviors that would reduce transmission and risk of COVID-19.

PurposeCellulase, due to its massive applicability, has been used in various industrial processes such as biofuels (bioethanol, triphasic biomethanation), agricultural and plant waste management, chiral separation, and ligand binding studies. The finding of a novel cellulase-producing bacterium will benefit the industries, which rely on yeast to produce cellulase in fermentation technology, because bacteria can easily be manipulated and fermented cost-effectively.MethodsCellulase enzyme-secreting bacteria were isolated from different regions of the world’s largest mangrove forests, Sundarbans in Bangladesh. Biochemical, morphological, and 16S rRNA identification protocol was followed to precisely characterize the bacterial strains.ResultWe have determined that the strain T2-D2 (Bacillussp.), E1-PT (Pseudomonassp.), and D1-PT (Pseudomonassp.) showed maximum endoglycolytic and strain C1-BT (Bacillussp.), E1-BT (Bacillussp.), and T-4 (E) showed relatively higher exoglycolytic activity during the test. So, it can be easily cultured at a normal temperature (97.7–99.5 °F). On the one hand, T2-D2 (Bacillussp.) and E1-PT (Pseudomonassp.) have shown the highest growth rate at pH 7 as it was neither acidic nor basic.ConclusionIt was concluded that the strain T2-D2 (Bacillussp.) and E1-PT (Pseudomonassp.) would be our target cellulolytic strains wherein the experimental isolates belonged to the Enterobacteriaceae, Psuedomonacea, Bacillacea, and Morganellacea family.
