Did the COVID-19 pandemic affect levels of burnout, anxiety and depression among doctors and nurses in Bangladesh? A cross-sectional survey study

INTRODUCTION

COVID-19 has caused severe disruption to clinical services in Bangladesh but the extent of this, and the impact on healthcare professionals is unclear. We aimed to assess the perceived levels of anxiety, depression and burnout among doctors and nurses during COVID-19 pandemic.

METHODS

We undertook an online survey using RedCap, directed at doctors and nurses across four institutions in Bangladesh (The Sheikh Russel Gastro Liver Institute & Hospital (SRNGIH), Dhaka Medical College Hospital (DMCH), Mugda Medical College Hospital (MMCH) and M Abdur Rahim Medical College (MARMC) Hospital). We collected information on demographics, awareness of well-being services, COVID-19-related workload, as well as anxiety, depression and burnout using two validated questionnaires: the Hospital Anxiety and Depression Scale (HADS) and the Maslach Burnout Inventory (MBI).

RESULTS

Of the 3000 participants approached, we received responses from 2705 (90.2%). There was a statistically significant difference in anxiety, depression and burnout scores across institutions (p<0.01). Anxiety, depression and burnout scores were statistically worse in COVID-19 active staff compared with those not working on COVID-19 activities (p<0.01 for HADS anxiety and depression and MBI emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA)). Over half of the participants exhibited some level of anxiety (SRNGIH: 52.2%; DMCH: 53.9%; MMCH: 61.3%; MARMC: 68%) with a high proportion experiencing depression (SRNGIH: 39.5%; DMCH: 38.7%; MMCH: 53.7%; MARMC: 41.1%). Although mean burnout scores were within the normal range for each institution, a high proportion of staff (almost 20% in some instances) were shown to be classified as experiencing burnout by their EE, DP and PA scores.

CONCLUSION

We identified a high prevalence of perceived anxiety, depression and burnout among doctors and nurses during the COVID-19 pandemic. This was worse in staff engaged in COVID-19-related activities. These findings could help healthcare organisations to plan for future similar events.

Variations in soil physico-chemical properties, soil stocks, and soil stoichiometry under different soil layers, the major forest region Liupan Mountains of Northwest China

Abstract Liupan Mountains are an important region in China in the context of forest cover and vegetation due to huge afforestation and plantation practices, which brought changes in soil physio-chemical properties, soil stocks, and soil stoichiometries are rarely been understood. The study aims to explore the distribution of soil nutrients at 1-m soil depth in the plantation forest region. The soil samples at five depth increments (0-20, 20-40, 40-60, 60-80, and 80-100 cm) were collected and analyzed for different soil physio-chemical characteristics. The results showed a significant variation in soil bulk density (BD), soil porosity, pH, cation exchange capacity (CEC), and electric conductivity (EC) values. More soil BD (1.41 g cm-3) and pH (6.97) were noticed in the deep soil layer (80-100 cm), while the highest values of porosity (60.6%), EC (0.09 mS cm-1), and CEC (32.9 c mol kg-1) were reflected in the uppermost soil layer (0-20 cm). Similarly, the highest contents of soil organic carbon (SOC), total phosphorus (TP), available phosphorus (AP), total nitrogen (TN), and available potassium (AK) were calculated in the surface soil layer (0-20 cm). With increasing soil depth increment a decreasing trend in the SOC and other nutrient concentration were found, whereas the soil total potassium (TK) produced a negative correlation with soil layer depth. The entire results produced the distribution of SOCs and TNs (stocks) at various soil depths in forestland patterns were 0→20cm > 20→40cm > 40→60cm ≥ 60→80cm ≥ 80→100 cm. Furthermore, the stoichiometric ratios of C, N, and P, the C/P, and N/P ratios showed maximum values (66.49 and 5.46) in 0-20 cm and lowest values (23.78 and 1.91) in 80-100 cm soil layer depth. Though the C/N ratio was statistically similar across the whole soil profile (0-100 cm). These results highlighted that the soil depth increments might largely be attributed to fluctuations in soil physio-chemical properties, soil stocks, and soil stoichiometries. Further study is needed to draw more conclusions on nutrient dynamics, soil stocks, and soil stoichiometry in these forests.

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial

BACKGROUND

Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial.

METHODS

EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110.

FINDINGS

Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001).

INTERPRETATION

Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor.

Initial Six Month's Study of Neonatal Covid-19 in a Tertiary Care Hospital of Bangladesh

The pandemic Covid-19 affects mainly adult causing fatal illness specially who have co-morbidities. But as days pass by with increasing surveillances it's gradually obvious that this devastating disease also affects the children as well as neonates with greater number. The aim of study was to determine the Covid-19 in neonates. So, we can give proper emphasis on neonatal Covid-19. This cross-sectional study was conducted from April 2020 to September 2020 at Dhaka Shishu (Children) Hospital in Bangladesh. Neonates with suspected Covid-19 were tested for SARS-CoV-2 by RT- PCR. Newborn who had suspected or confirmed COVID-19 mother, exposed to relatives infected with Covid-19, related with cluster outbreak or with abnormal clinical courses such as respiratory distress, not responded to conventional treatment and also abnormal chest x-ray was selected for Covid-19 test. Data regarding gestational age, birth weight, gender, positive cases and other findings were collected and analyzed. Statistics analysis was done by SPSS version 26.0. Forty three cases were Covid-19 positive. Among them 28(65.1%) cases were male and 15(34.9%) female. Term was 39(90.6%) cases and preterm 4(9.4%). Twenty nine (67.5%) cases were belonged to medicine and 14(32.6%) surgical cases. Fourteen (32.5%) cases with Covid-19 lived in Dhaka and 29(67.5%) cases in outside of Dhaka. Eleven (25.5%) cases were positive for SARS -CoV-2 by RT- PCR within 3 days, among them 5 (11.6%) cases were within 24 hours of age. Nine (20.9%) and 23(53.5%) cases were test positive at day 4-7 and 8-28 days respectively. The main symptoms at admission were respiratory difficulty (12/43, 27.9%), fever (8/43, 18.6%), convulsion (8/43, 18.6%) and reluctance to feed (7/43, 16.6%). In neonate two or more diseases coexist in same cases. Sepsis was present in 20 (46.5%) cases with COVID-19. Perinatal asphyxia was present in 10(23.3%) and pneumonia in 8 (18.6%) cases. In laboratory findings low Hb% was present in 2/43(4.7%) cases, leukopenia in 4/43(9.3%), leukocytosis in 2/43(4.7%) and thrombocytopenia in 5/43(11.6%). Elevated CRP was present in 14/29 (32.6%) cases, hypernatremia in 10/33 (30.3%), hyponatremia in 1/33(3%), increased serum creatinine in 10/18(55.6%), and prolonged PT, aPTT in 2/2(100%). Hyperglycaemia was found in 1/15(6.7%) cases and hypoglycaemia in 2/15(13.3%). No organism was found in blood C/S. In chest X-ray, one showed patchy opacities in right lower lobe, another showed bilateral ground-glass opacity and third one revealed few patchy opacities in the right perihilar region. Among 43 cases 21(48.9%) were discharged with advice, 12(27.9%) cases referred to Covid-19 designated hospital, 2(4.7%) cases LAMA (Leave against medical advice) and 8(18.6%) cases died including one surgical case. A good number (43) of Covid-19 cases were found in this study. In neonates the clinical features could not be differentiated properly between Covid-19 or associated diseases unlike children and adult. The neonate may be a source of transmission of this disease. So, we should give proper emphasis on test, tracing and management of neonatal Covid-19.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial

BACKGROUND

The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population.

METHODS

EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110.

FINDINGS

Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1).

INTERPRETATION

In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

3D Dosimetry for Electron Flash Radiotherapy: Assessment of Radiochromic Dosimeter Phantoms with Optical CT Scanning as a 3D Dosimetry System

PURPOSE/OBJECTIVE(S)

Many of the dosimeters used in conventional radiation therapy exhibit dose rate dependence which prohibits their use in ultra-high-dose-rate (FLASH) radiation therapy. Radiochromic plastic dosimeter PRESAGE® has been used for 3D dosimetry for many years. We hypothesized that these phantoms would show dose-rate independence throughout both the conventional and FLASH RT regimes, indicating these phantoms exhibit qualities useful for relative 3D dosimetry in FLASH electron beams.

MATERIALS/METHODS

FLASH experiments were performed using a commercially available linear accelerator, converted to deliver an ultra-high-dose-rate 10 MeV electron beam. The LINAC delivered approximately 0.7 Gy/pulse for FLASH irradiations. Dose rate was varied from about 40 Gy/s to 240 Gy/s by changing the repetition rate. PRESAGE phantoms were irradiated en face at six FLASH dose rates: 40 Gy/s, 80 Gy/s, 120 Gy/s, 160 Gy/s, 200 Gy/s, and 240 Gy/s. EBT film and scintillator measurements were used to verify dose delivered. The optical response of the PESAGE phantom versus delivered dose was evaluated with various known doses. A novel parallel-beam optical CT scanner, utilizing fiber optic taper for collimated images, was developed for fast, high resolution, and accurate readout of 3D dosimeters. Percent depth dose curves for various FLASH dose rates and conventional dose rate beams were generated and compared based on the optical response versus dose measurements. Percent depth dose curves from Monte Carlo calculation of the presage phantom were also compared.

RESULTS

As shown in Table 1, the percent depth dose as a function of depth for six FLASH dose rates (240-40 Gy/s) are nearly identical, indicating that optical response of PRESAGE is dose-rate independent. The optical density of PRESAGE phantom was confirmed to be linear with absorbed dose for all FLASH dose rates, consistent with the observation at regular treatment dose rates.

CONCLUSION

PRESAGE phantoms show dose-rate independence in electron beams for a wide range of dose rates from conventional to ultra-high-dose-rates, indicating these phantoms can be useful for relative 3D dose measurements in FLASH electron beams. Future experiments will be undertaken as part of the commissioning of a commercially available FLASH radiotherapy unit.

Socioeconomic disparities in diabetes-concordant comorbidity: national health interview survey, 1997-2018

OBJECTIVE

Although social disparities in morbidity and mortality are well-documented, little is known how socioeconomic status (SES) shapes diabetes-concordant comorbidity (DCC). This study examines socioeconomic inequalities in DCC among adults with diabetes in the United States.

STUDY DESIGN

The study incorporated a cross-sectional nationally representative household health survey.

METHODS

This study used data from the National Health Interview Survey, 1997-2018. The analysis included 56,192 adults aged 30 or above with diabetes. Multinomial logistic regression was used to obtain relative risk ratios in gender-stratified models after adjusting for sociodemographic covariates.

RESULTS

The multivariable-adjusted analyses suggest that across all SES indicators and in both men and women, individuals with lower SES had greater odds of DCC than individuals with higher SES. The associations of SES indicators with DCC were larger in magnitude among women than in men. For example, compared to individuals with a college or higher degree, men with less than a high school degree were 2.06 times (95% confidence interval = 1.76-2.41) and women with less than a high school degree were 3.19 times (95% confidence interval = 2.67-3.82) more likely to have 3 or more DCCs. Similar associations were observed for other indicators of SES.

CONCLUSION

Study findings suggest strong social status and gender-based patterns in DCC. Identifying population groups with poor social status may be useful for informing interventions aiming to improve healthcare services of diabetes-related complications.

Short-term Treatment Outcome of Patients with Acute ST-elevation Myocardial Infarction in a Tertiary Care Hospital

Outcome of acute ST-elevation myocardial infarction patients varies time to time. The present study was intended to find out the short-term treatment outcome of the patients admitted in hospital. This descriptive study was carried out in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 15 January 2014 to 14 July 2014. A total of 100 patients admitted with Acute ST-elevation Myocardial Infarction confirmed on the presence of the (a) Typical chest pain of acute ST-elevation Myocardial Infarction (b) Electrocardiogram (ECG) evidence of ST segment elevation in two or more contiguous leads (c) Raised cardiac marker (Troponin I) were included in the study. Patients were randomly enrolled according to the inclusion and exclusion criteria and observe for one week. Data were processed and analyzed by using computer bases software SPSS version 19.0. Descriptive statistical methods were applied for data analysis. P value was considered as statistically significant when it is less than 0.05. Short-term treatment outcome of acute ST-elevation myocardial infarction include mechanical, arrhythmic, ischemic and inflammatory sequelae, as well as left ventricular mural thrombus. In addition to these broad categories, heart failure, arrhythmia, death are other common complications of AMI. The initiation of the complications usually results in explicit sign and symptoms of the acute MI patients. Learning of the complications in the post infarction period and the clinical syndromes develop with each complication, will allow the health care worker to evaluate and manage the complication appropriately.

Role of Doppler Ultrasound in Diagnosis of Hepatocellular Carcinoma with Histopathological Correlation

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the leading cause (possibly third) of cancer mortality. In a present scenario, HCC displays a challenging clinical problem worldwide. Good-quality ultra sound with careful evaluation of the hepatobiliary system can be a screening examination for HCC in patients at risk. The aim of the study was to determine the diagnostic accuracy of the Doppler sonography for differentiation of hepatocellular carcinoma (HCC) from other focal liver lesions. It was a cross-sectional survey, conducted in the Department of Radiology& Imaging, Mymensingh Medical College, Mymensingh, Bangladesh from January 2017 to December 2018. A total of 70 patients with space occupying lesions on ultrasound were included in this study while pregnant women were excluded. All patients were examined by gray scale ultrasonography, color Doppler and FNAC. To visualize the blood flow, standard color Doppler sonography was used for each lesion. Within the lesions, pulsed Doppler samples were assessed whenever possible on the basis of pulsatile flow & finally resistive index (RI) of intra-tumoral and peritumoral arterial flow was studied. After evaluating by Doppler sonography (CDFI and Spectral analysis), FNAC was done and the specimen was sent to the Department of Pathology for Cytopathological examination. Cytopathology were assessed for confirmation of positive and negative cases of HCC. The detection rate of arterial flow in malignant tumors was 85.1% and in benign lesions were 30.4%. Doppler spectrum analysis showed that the resistive index in primary malignant tumors were 0.76±0.12 and in metastatic tumors were 0.80±0.12 and below 0.6 in benign lesions. The difference was significant (p<0.001). This difference was related with its Cytopathological report. The arterial flow identified by CDFI within the liver lesion with RI >0.6 can be regarded as a criterion of malignant tumors and RI<0.6 can be regarded as benign lesions. This study concluded that the combination of color Doppler flow imaging and RI are more useful in differential diagnosis of liver neoplasms.

Socio-economic inequalities in undiagnosed, untreated, and uncontrolled diabetes mellitus in Bangladesh: is there a gender difference?

OBJECTIVES

We aimed to determine: (1) the prevalence and socio-economic distribution of undiagnosed, untreated, and uncontrolled diabetes mellitus (DM); (2) the relationship between socio-economic status (SES) and undiagnosed, untreated, and uncontrolled DM; and (3) if this relationship is mediated by gender.

STUDY DESIGN

Cross-sectional nationally representative household-based survey.

METHODS

We used data from the Bangladesh Demographic Health Survey from 2017 to 18. Our findings were based on the responses of 12,144 individuals aged 18 years and older. As a measure of SES, we focused on standard of living (hereinafter referred to as wealth). The study's outcome variables were prevalence of total (diagnosed + undiagnosed), undiagnosed, untreated, and uncontrolled DM. We used three regression-based approaches-adjusted odds ratio, relative inequality index, and slope inequality index-to assess different aspects of SES differences in the prevalence of total, undiagnosed, untreated, and uncontrolled DM. We used logistic regression analysis to look at the adjusted association between SES and the outcomes after gender stratification to see whether gender status moderates the association between SES and the targeted outcomes.

RESULTS

In our sample analysis, the age-adjusted prevalence of total, undiagnosed, untreated, and uncontrolled DM was 9.1%, 61.4%, 64.7%, and 72.1%, respectively. Females had a higher prevalence of DM and undiagnosed, untreated, and uncontrolled DM than males. When compared to people in the poor SES group, people in the rich and middle SES groups had 2.60 times (95% confidence interval [CI] 2.05-3.29) and 1.47 times (95% CI 1.18-1.83) higher chance of developing DM. When compared to individuals in the poor SES group, those in the rich SES groups were 0.50 (95% CI 0.33-0.77) and 0.55 times (95% CI 0.36-0.85) less likely to have undiagnosed and untreated DM.

CONCLUSIONS

In Bangladesh, rich SES groups were more likely than poor SES groups to have DM, whereas poor SES groups with DM were less likely than rich SES groups to be aware of their disease and obtain treatment. The government and other concerned parties are urged by this study to pay more attention to developing suitable policy measures to reduce the risk of DM, particularly among rich SES groups, as well as targeted efforts to screen for and diagnose DM in socio-economically disadvantaged groups.

Prevalence and Associated Risk Factors of Postpartum Anestrus in Dairy Cows of Sylhet District, Bangladesh

The objectives of current study were to assess the prevalence and risk factors associated with postpartum anestrus in lactating dairy cows in Sylhet region, Bangladesh. A total of 420 postpartum cows of different breed and age were selected randomly from different dairy farms in studied area. Structured questionnaire was used to collect data from farm owner on prevalence and risk factors for postpartum anestrus. Observed heat within 60 days after parturition was considered as normal cyclic cows and others were considered as postpartum anestrus. The prevalence of postpartum anestrus was 36.20%. The study shows that older cows take relatively more time for ovarian resumption. Cow’s having first parity shows cyclicity within 60 days of parturition, and postpartum anestrus increases significantly with the advancement of parity. Postpartum anestrus was significantly higher (P< 0.001) in cows with poor (≤1.0) and excessive (>3) body condition scores (BCS), respectively, compared to those with moderate/optimal BCS (2–3). The postpartum cyclicity in cows within 60 days with a history of normal placental expulsion was significantly higher than in the cows with RFM. Ovarian cyclicity was highest (75.92%) among the cows that were maintained in adequate hygienic conditions and lowest (43.51%) in a poor environment. The highest percentage (88.10%) of cows showed postpartum cyclicity with a history of short lactation length (0-150 days) and resumption of postpartum estrous cycle increases significantly with lactation length. Resumption of postpartum estrus cycles in cows takes more time with a history of minimal (<15 liters) daily milk production than the cow with medium (>15-25 liters) daily milk production. Cows get an adequate feed supply (both concentrate and green grass), which shows a positive effect on postpartum cyclicity. Pre and postpartum complications have a significant (p<0.001) effect on the postpartum cyclicity of cows. Endometritis (81.25%) followed by pyometra (75.76%) were recorded as major reproductive obstacles in ovarian resumption, whereas uterine prolapse (70.59%) followed by abortion (61.54%), milk fever (58.33%), stillbirth (58.33%) and dystocia (57.63%) were the major recorded complications in post-partum phase. The study also revealed that the non-restricted suckling period has a significant (p<0.001) negative effect on ovarian resumption. The risk factors including parity, BCS, placental expulsion, hygienic condition, lactation length, daily milk production and management system were significantly (P<0.01) influenced the postpartum cyclicity. Maintaining optimal BCS of cows, proper hygienic and good management practice, and farmer's training on management of cattle reproduction would improve the number of cows for breeding by 60 days postpartum.

Clinico-epidemiological Characteristics of Asymptomatic and Symptomatic COVID-19-Positive Patients in Bangladesh

As of August 15, 2020, Bangladesh lost 3591 lives since the first Coronavirus disease 2019 (COVID-19) case announced on March 8. The objective of the study was to report the clinical manifestation of both symptomatic and asymptomatic COVID-19-positive patients. An online-based cross-sectional survey was conducted for initial recruitment of participants with subsequent telephone interview by the three trained physicians in 237 adults with confirmed COVID-19 infection in Bangladesh. The study period was 27 April to 26th May 2020. Consent was ensured before commencing the interview. Collected data were entered in a pre-designed case record form and subsequently analyzed by SPSS 20.0. The mean±SD age at presentation was 41.59±13.73 years and most of the cases were male (73.0%). A total of 90.29% of patients reside in urban areas. Among the positive cases, 13.1% (n=31) were asymptomatic. Asymptomatic cases were significantly more common in households with 2 to 4 members (p=0.008). Both symptomatic and asymptomatic patients shared similar ages of presentation (p=0.23), gender differences (p=0.30) and co-morbidities (p=0.11). Only 5.3% of patients received ICU care during their treatment. The most frequent presentation was fever (88.3%), followed by cough (69.9%), chest pain (34.5%), body ache (31.1%), and sore throat (30.1%). Thirty-nine percent (n=92) of the patients had co-morbidities, with diabetes and hypertension being the most frequently observed. There has been an upsurge in COVID-19 cases in Bangladesh. Patients were mostly middle-aged and male. Typical presentations were fever and cough. Maintenance of social distancing and increased testing are required to meet the current public health challenge.

A Case of Ambiguous Lineage Acute Leukemia Posing Diagnostic Challenge

Introduction/Objective

N/A.

Methods/Case Report

Acute leukemias with ambiguous lineage encompass those leukemias that show no clear evidence of differentiation along a single lineage and account for less than 4% of all cases of acute leukemias and often poses diagnostic dilemma. We present a challenging case of an ambiguous lineage acute leukemia in a previously healthy 27-year-old male, who presented to the ED with acute fever, dyspnea on exertion, nausea and vomiting. A complete blood count (CBC) showed a white blood cell count of 323 × 109/L, Hemoglobin of 3.3 g/dl, Platelet count of 44 × 109/L and a differential count of Neutrophil: 11, Lymphocyte: 31, Monocyte: 02, Band Neutrophil:1, Myelocyte :1, Blast: 54. Bone marrow aspirate smears revealed a heterogenous population of small to large sized blasts comprising 83% of cellularity. They expressed scant to moderate basophilic cytoplasm, high N/C ratio, round to irregular nuclear contour, finely granular chromatin and some with nucleoli. Other lineages were markedly suppressed. Flow cytometric analysis revealed an abnormal blast population (~80% of total) expressing CD34, HLA-DR, Tdt (subset), CD71 (dim) and CD38. In addition, the blasts expressed myeloid associated antigens CD13, MPO (smaller subset), as well as B-cell associated antigens CD19 (dim), cytoplasmic CD22 and cytoplasmic CD79a. They also expressed T-cell associated antigens, CD2, CD3 (smaller subset), CD5 (subset) and CD7 (subset) but negative for cytoplasmic CD3. This unusual pattern of expression posed a challenge as to what type of mixed phenotype leukemia it should be with variable expressions from all three lineage of myeloid, B- and T-cell. Further work-up showed, scattered blasts are also positive for MPO by cytochemical (on aspirate smear) and immunohistochemical stain (on core). The latter also showed negativity for CD3. Based on all these findings, this mixed phenotype acute leukemia (MPAL) was best categorized as MPAL (B/myeloid) over so called “Triphenotypic (B/T/myeloid) acute leukemia”. We considered expression of myeloid and B cell markers as more lineage defining in this case as compared to small subset expressing T lineage marker CD3. This case exemplifies the importance of multimodal comprehensive analysis of acute leukemia, especially in the setting of MPAL with expression of multi- lineage markers posing a diagnostic challenge.

Making physical examination in medicine user-friendly

Physical examination (PE) techniques used in medical schools appear redundant in several aspects: unnecessarily regimental, lacking in efficiency, and lengthy. Many techniques are sustained solely because of the age-old tradition. This commentary suggests a simplification of PE techniques to make them acceptable to all the stakeholders, such as patients, medical students, and medical teachers. This is especially relevant in this era when imaging is widely used for diagnosis, and the confidence and reliance on PE are declining. Opinions of 10 senior consultants active in medical practice, teaching, and assessment were sought to know their concurrence with the authors' views. Seven of them provided their opinions, which showed considerable agreement with the authors' views regarding PE. All the items presented in this paper are mostly supported by the opinions of the senior consultants, textbooks, and literature. We consider sharing this work with the fraternity worthwhile.

Echocardiographic Evaluation of Cardiac Changes in Patients with Hypothyroidism and the Response to Treatment

Thyroid hormone acts on heart and peripheral vascular system in multiple ways. Most of the cardiac manifestations are reversible with adequate and timely thyroid therapy. Echocardiographic changes are present in patients with untreated hypothyroidism and the changes are reversible with treatment. Aim of the study was to evaluate the structural and functional changes of the heart in hypothyroid patients and its response to treatment. This prospective observational study was performed in the Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from November 2012 to April 2013. The study included 35 cases and 35 control based on their thyroid hormonal status. The cases were previously untreated for hypothyroidism. By 2D and M-mode echocardiography LV septal wall and posterior wall thickness, LVIDD, LVIDS, LA and Aortic diameter and ejection fraction were measured. Mitral inflow pattern was observed through pulse wave Doppler and peak E velocity, a velocity and E/A ratio were noted. All the observations were noted both in cases and controls and in cases after normalization of hypothyroid status. Echocardiographic variables showed that septal wall and posterior wall thickness, LVIDD and LVIDS were higher in the cases than those in the control group. Left ventricular ejection fraction was lower in case group compared to control group. Of the mitral inflow parameters, a velocity was higher and E/A ratio lower in cases than those in control group. Following treatment of >3 months the septal wall and posterior wall thicknesses were reduced significantly (p<0.001 and p<0.001 respectively) and Left ventricular ejection fraction was also improved significantly (p<0.001) from its baseline status. Of the mitral inflow parameters, E-velocity was significantly increased, A-velocity significantly decreased and E/A ratio significantly increased from their baseline figures (p=0.016, p=0.032 and p<0.001 respectively). Cardiovascular complications of hypothyroidism increase the morbidity of the patients. Results of our study showed importance of early diagnosis and prompt treatment reversed the condition and that will diminish the extent of cardiac complications.

POS0640 REAL-WORLD EFFECTIVENESS AND SAFETY OF GP2015 IN PATIENTS WITH RHEUMATIC DISEASES: FINAL RESULTS OF THE COMPACT STUDY

Background

COMPACT is a non-interventional study evaluating the effectiveness and safety in patients (pts) with rheumatoid arthritis (RA), axial-spondyloarthritis (axSpA) or psoriatic arthritis (PsA) treated with GP2015 (an etanercept [ETN] biosimilar) in real-world conditions.

Objectives

We present the effectiveness and safety data from the final analysis of the COMPACT study for all patient groups.

Methods

Pts aged ≥18 years on treatment with GP2015 were enrolled. Baseline visit corresponded with date of study inclusion and not with date of GP2015 treatment start. Pts were categorised based on prior treatment status: pts on clinical remission or low disease activity under treatment with reference ETN or biosimilar ETN (initial ETN: [iETN]) and switched to GP2015 (Group A) or pts who received non-ETN targeted therapies and switched to GP2015 (Group B) or biologic-naïve pts who started GP2015 after conventional therapy failure (Group C) or DMARD-naïve pts with recent diagnosis of RA considered suitable for treatment initiation with a biologic and started on treatment with GP2015 (Group D). Effectiveness assessments included Disease Activity Score 28-joint count Erythrocyte Sedimentation Rate (DAS28-ESR) or Ankylosing Spondylitis Disease Activity Score (ASDAS) until Month 12 after enrolment (baseline) in the study.

Results

Of the 1466 pts enrolled, 572 were switched from iETN (Group A), 171 were switched from other targeted therapies (Group B), 713 were biologic-naïve (Group C), and 10 were RA DMARD-naïve (Group D). Comorbidities were more frequent in pts with RA (68.7%,) followed by pts with PsA (59.4%) and axSpA (52.1%). After 12 months of treatment with GP2015, pts with RA or PsA achieved comparable DAS28-ESR scores irrespective of whether they switched from iETN, or from other targeted therapies or were biologic-naïve. At Month 12, the mean ASDAS scores were comparable between the treatment groups in pts with axSpA (Table 1). Across all pt groups, no major differences were observed in the disease activity scores between baseline and Month 12 that may be explained by the ongoing GP2015 treatment at the time of enrolment for an observed average of 138 days. Overall, the proportion of patients with at least one adverse event (AE) and serious AE (SAE) was 47.6% and 7.7% in pts who were switched from iETN, 56.7% and 9.9% in pts switched from other targeted therapies, 56% and 8.7% in biologic-naïve pts, and 60% and 0% in DMARD-naïve pts. Rate of injection site reaction was low across the groups (Figure 1).

Evaluation of Short Term Outcome of Stapled Transanal Rectal Resection (STARR) for ODS (Obstructed Defecation Syndrome) by Comparing Pre and Post-operative ODS Score

Obstructed defecation syndrome (ODS) is a common anorectal problem and it can be corrected by various surgical approaches but most of these have high recurrence and complication rates. Antonio Longo introduced Stapled transanal rectal resection (STARR) in 2003 as a minimally invasive transanal operation for correction ODS associated with rectocele and or rectal intussusception. This study was designed to assess the short term outcome of Stapled Transanal Rectal Resection (STARR) as a surgical treatment of Obstructed Defecation Syndrome (ODS). This is a quasi experimental study which was carried out in the department of Colorectal Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from May 2016 to June 2017. Seventeen (17) patients were included in the study. Patients with obstructed defecation syndrome and rectocele and or rectal intussusception admitted in the department of Colorectal Surgery were enrolled in the study as per inclusion and exclusion criteria. History, clinical examination, Proctoscopy, Colonoscopy and MR Defecography was done for evaluation of the patients. During evaluation preoperative Longo's ODS score of every patient also determined and compared with postoperative ODS score. The patient was followed up regularly at one, three and six months after each operation. The ODS score in 82.35% patients improved significantly. The postoperative score was high (13-15) only in 02(11.8%) patients probably due to presence of physiological factors. Post-operative defecatory urgency was developed in only 02(11.76%) patients. Major postoperative complication like hemorrhage or rectovaginal fistula did not develop in any patient. STARR is an effective, less invasive and simple procedure for the treatment of ODS with rectocele and/or rectal intussusception without major morbidity but other physiological causes of ODS should exclude preoperatively because its presence makes the surgical intervention fruitless.

Estrogen Status and Trigeminal Ganglion Responses to Jaw Movement

Chronic temporomandibular joint disorders (TMDs) present with pain in the temporomandibular joint (TMJ) and muscles of mastication. Risk factors for TMD include localized joint/muscle inflammation and estrogen status. This study determined whether mild tissue inflammation and estrogen status influenced the responses of trigeminal ganglion neurons to jaw palpation or jaw movement, 2 key diagnostic features of clinical TMD, in adult rats. Neuronal activity was recorded from male rats, ovariectomized (OvX) female rats, and OvX female rats injected with 17β-estradiol 24 h prior to testing (OvXE). Neurons were tested for responses to deep press over the TMJ region and jaw movement in 3 directions (open, protrusion, lateral) 10 d after intra-TMJ injection of a low dose of complete Freund's adjuvant (CFA) or vehicle (sham). Deep press evoked similar responses in all treatment groups. The response magnitude to jaw opening and protrusion was significantly greater for neurons recorded from OvXE CFA-treated rats than from OvX CFA-treated or OvXE sham rats. The responses to lateral movement of the jaw were similar across all treatment groups. Most neurons (70% to 90%) displayed a static response pattern to jaw movement independent of direction. Estradiol treatment also increased the proportion of neurons that were excited by jaw movement in >1 direction as compared with untreated OvX females or males. These results suggest that mild localized inflammation in the TMJ region during periods of elevated estrogen were sufficient to increase the peripheral driving force for jaw movement-evoked hyperalgesia.

A repeating fast radio burst source in a globular cluster

Fast radio bursts (FRBs) are flashes of unknown physical origin¹. The majority of FRBs have been seen only once, although some are known to generate multiple flashes^2,3. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission^4,5. Recently, the discovery⁶ of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths⁶. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system⁷. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts.

Prevalence rate of attention deficit hyperactivity disorder (ADHD) and computer vision syndrome (CVS) symptoms predisposition among digital device users of Bangladesh

Background

Around 5.29% of the world population is suffering from ADHD, and 60 million people are suffering from CVS, with an increasing rate of prevalence of these disorders. This study aimed to determine the prevalence rate of ADHD and CVS symptoms among the Bangladeshi population.

Results

To assess the aim of the study, a cross-sectional survey was conducted online through stratified sampling, and 197 responses were collected from the participants. Our survey method follows these criteria where the ARSV1.1 standard questionnaire was followed for the ADHD questionnaire, and a self-administered questionnaire was established based on the symptoms of CVS. The male age ranges from 18–24 have the highest value of ADHD (34%) coincided with > 6 h digital device usage (51%), and the Stroop effect is significantly correlated with the ADHD score (0.498, p < 0.01). The Stroop effect value is also higher among the males aged 18–24, digital device users for > 6 h (48%).

Conclusions

With the advent of science, it is impossible to avoid digital devices as necessary. Notwithstanding, safe and appropriate use of digital media is a must for healthy living.

Assessment of hygienic and sanitation practices among poultry butchers in selected Municipality areas of Assam (India)

A study was conducted in Dhubri and Biswanath Chariali Municipality areas to assess the adoption of hygienic and sanitation practices being followed by poultry butchers. A total of 60 poultry butchers were selected randomly, 30 from each Municipality area so that the final sample consisted of 60 poultry butchers. Data were collected using a pre-tested structured interview schedule by personal interviews. The schedule was designed to collect information on the socioeconomic profile of the butchers, personal and meat shop hygiene, maintenance of meat shop and its equipment. The data revealed that all the poultry butchers were male among which (75%) of them had an education level only up to eight standard. The overall mean age of the poultry butchers was found to be 39.95±8.64 years of which majority (75%) of them belong to middle age group. The present study indicated that none of the poultry butchers underwent any formal training for hygienic meat handling. It was also pointed out that most (85%) of the butcheries were located at market area, while only a few (15%) were found in the residential area. Only 18.33 per cent of the poultry butchers wore clean clothes while 81.67 per cent of them did not adopt this practice during working. Majority (88.33%) of them did not wash their hands after smoking/ chewing tobacco.It was also revealed that majority (88.33%) of the butchers did not clean knives before and after cutting of meat. Majority of the butchers agreed that cleanliness of equipment (71.67%), the meat shop and its surrounding (68.33%) and personal hygiene (68.33%) were some of the important factors that were essential to ensure wholesome meat production. From the above study, it may be concluded that appropriate interventional measures by the concerned agencies such as awareness trainings for poultry butchers on crucial areas of food safety, hygienic practices relating to meat handling and personal safety are imperative. The results of the study also shed light on the need for measures to improve the infrastructural facilities in poultry meat butcheries and for appropriate interventions to strengthen the food quality control system by the government regulatory authorities.

Diseases Pattern and Outcome among the Neonates in A Newly Established Special Care Newborn Unit (SCANU) At Secondary Level District Hospital in Bangladesh

Although huge improvement in neonatal mortality reduction in last two decades in Bangladesh but it is still very high compare with many other countries. High neonatal mortality also significantly contribute deaths among the under five children. Neonatal mortality reflects a nation's socio-economic status, efficiency and effectiveness of health care services. This was cross sectional study. The objective of this study was to analyse the diseases pattern and outcome of the neonates admitted in the newly established SCANU (Special care neonatal unit) of 250 bedded General Hospital of Tangail district, Bangladesh. Study period was one year from January 2017 to December 2017. Information from medical records of the SCANU was analysed. During the study period 1,379 neonates were admitted in the SCANU. The ratio between male and female was 1.5:1, 61% of the neonates admitted at first day of life. The reasons for admissions in SCANU were 31% of preterm and low birth weight, 23%birth asphyxia, 13% neonatal sepsis, 9% transient tachypnea of newborn, 5% congenital anomalies and 4% neonatal jaundice. Out of all neonates survival rate was 56% (779), while 25% (349) ended with fatality, 9% (122) were referred to tertiary level hospital and 10% (129) were left the hospital against medical advice. Among the fatal cases 63% died in first 24 hours and 88% in first week of life. Data shows that 47% deaths were due to preterm and low birth weight with its complication, other significant causes were birth asphyxia (30%), septicemia (16%) and congenital anomalies were (6%). Preterm and low birth weight, neonatal sepsis, birth asphyxia, transient tachypnea of newborn; congenital anomalies were the main reasons for admission in SCANU. Prematurity and its complication, birth asphyxia and neonatal sepsis as the major contributors to the neonatal mortality. The study findings will help researchers and policy makers to initiate further research and interventions to reduce fatality among the neonates in the SCANU.

A Middle-Aged Woman Presented with Catastrophic Anti-phospholipid Syndrome in Nephrology Department of BSMMU

A life threatening rare condition called catastrophic antiphospholipid syndrome leading to multiple organ failure is characterized by vascular thrombosis in the presence of anti-phospholipid antibody which often appear as a medical emergency. Antiphospholipid antibody syndrome whether primary or secondary cause thromboembolic manifestation resulting recurrent fetal loss, but catastrophic antiphospholipid antibody syndrome may not present in such a way, rather multi-system involvement occurs within a short period of time. We would like to present a case of 50 years old female who is hypertensive, non-diabetic, a known case of hypothyroidism for two years, who was admitted to our hospital after developing fever for 7 days and black discoloration of lateral three fingers of left hand for short period of time. The patient had no medical problems and had been in her usual state of health until 7 days before admission. Patient is anaemic and found to have severe renal failure. She was found high titer antiphospholipid antibody both IgM and IgG positive and anti-cardiolipin antibody positive. Her routine investigations revealed very high neutrophilic leukocytosis, high acute phase reactant, urinary findings revealed no active sediment; we thought that our patient might have sepsis that may trigger catastrophic antiphospholipid syndrome. Multi-disciplinary consultation gave us valuable opinion. Considering her septicemia, she was given broad spectrum antibiotic. Anticoagulation was given with unfractionated heparin followed by warfarin and as an immunosuppressive protocol methylprednisolone followed by prednisolone along with pulse cyclophosphamide was given. Treatment option with plasma pheresis and monoclonal antibody was not attempted, but she was given several session of hemodialysis, within a few days her biochemical parameters improved. Severe renal failure in this patient may be explained by septicemia or thrombotic micro-angiopathy that was reversed with anti-coagulation or proper antibiotic. Amputation of three digit of left hand was done by orthopedic surgeon but unfortunately two weeks after admission the patient expired due to sudden stroke.

Quantifying egg attendance behaviours of wild Asian houbara can improve artificial incubation outcomes

Artificial incubation is fundamental in ex situ avian conservation interventions for an increasing range of threatened species, but incubation parameters can differ between species. Both egg-turning angle and frequency are critical for successful embryonic development, but measuring these parameters in wild birds has historically been difficult. Using data-loggers inside artificial eggs that accurately record parental egg attendance behaviours, we quantified turning angles and rates throughout the incubation of 6 nesting wild Asian houbaras Chlamydotis macqueenii, a species bred in captivity in response to human over-exploitation. Wild females turned their eggs 0.6 times h-1 with a mean angle of 40.9° turn-1. Mimicking the patterns of wild birds (‘wild’ treatment), we applied a mean angular change of 40-50° turn once h-1 to artificially incubated eggs and compared this to eggs treated with an existing protocol (‘control’) of 120-130° per turn. Mean hatchability for the wild treatment (78.8%, n = 766) was similar to the control (76.6%, n = 1196). The wild treatment (n = 591) produced significantly heavier hatchlings (2.7%) than the control treatment (n = 893). However, chick growth rates (g d-1 and daily % mass change) and survival to Day 10 were not different between groups. The wild treatment demonstrates that turning angles affect embryo development and, perhaps, hatchability. Investigating natural incubation behaviours using egg-loggers and applying these patterns to artificial incubation appears efficacious to achieve optimal incubation protocols and reduce the need for ex situ trial and error refinement in conservation interventions of captive-bred threatened bird species.

A Rare Case of Polyorchidism: Sonographic and MR Evaluation of Four Testes

Polyorchidism is a rare congenital anomaly reported about 200 cases in the world text. A number of theories have been planned concerning the making of polyorchidism, but the real explanation is still not acknowledged. Here we are going to present a case study of polyorchidism. A 70 years old gentleman complained with left supernumerary testes in the left hemiscrotum. His left hemiscrotum was painless with mass. Polyorchidism without malignancy or any other concomitant features were revealed by both ultrasound and MRI examinations. In most cases the ultrasonograph alone is diagnostic. In complicated cases of polyorchidism MRI may provide additional information.

Effect of boiling and roasting on physicochemical and antioxidant properties of dark red kidney bean (Phaseolus vulgaris)

The effects of two processing methods (boiling and roasting) on physicochemical qualities of dark red kidney bean (Phaseolus vulgaris) were investigated. Changes in total polyphenol content (TPC) and antioxidant activity due to processing were also analyzed by using Folin–Ciocaltue method and 1,1 diphenyl-2-picrylhydrazyl (DPPH) assay, respectively. Analysis of physicochemical properties exhibited substantial variations (p<0.05) in the levels of moisture, ash, protein, fat, carbohydrate, gross energy and pH of raw and processed beans. Meanwhile, there was no considerable difference (p<0.05) in the fibre content of fresh and processed beans. Investigation of total phenolic content showed the significant (p<0.05) reduction of phenolic compounds in boiled (5.53±0.74 mg GAE/ g) and roasted (8.15±1.60 mg GAE/g) beans than raw samples (12.55±1.42 mg GAE/g). DPPH radical scavenging activity was also decreased significantly (p<0.05) in boiled and roasted samples with IC50 value of 0.0608±0.0765 mg/mL and 0.0523±0.0026 mg/mL, respectively. In the case of household cooking, keeping boiling water would be advised for the preservation of minerals, vitamins and phenolic compounds. The roasting process may be used to develop high-quality health-promoting dark red kidney bean products.

Bioactive compounds and antioxidant activity of black and green tea available in Bangladesh

People in Bangladesh are traditionally used to consume mainly black tea. However, some tea manufacturing companies are now producing green tea, though in a small scale. To create new knowledge as well as awareness about the consumption of green tea, the present study was carried out to compare the black and green tea available in Bangladesh based on their bioactive compounds and antioxidant activity. A total of eight brands of black tea and two brands of green tea were bought from the supermarkets. Total phenolics, total tannin, total flavonoids, and caffeine content were measured as bioactive compounds, and antioxidant activity was evaluated by using two different methods such as DPPH (1,1- diphenyl-2-picrylhydrazyl) radical-scavenging activity and ABTS+ radical scavenging activity of methanol extracts of black and green tea. Every bioactive compound in black and green tea was found to be significantly different (P < 0.05). The total phenolic content, on average, was measured at 242.46 mg GAE/g dry extract and 763.41 mg GAE/ g dry extract in black and green tea, respectively. Black tea contained 6.47 mg TAE/g dry extract tannin, whereas green tea had much more tannin content, 14.51 mg TAE/g dry extract, which is more than double in amount. On the other hand, the total flavonoid content was almost double in black tea (61.82 mg QE/g dry extract) compared to green tea (31.85 mg QE/g dry extract). Antioxidant activities were determined at different concentrations of tea samples. At every concentration, green tea presented higher ABTS+ and DPPH radical scavenging activity than black tea. The highest percentage of inhibition was observed at 20 ppm both in black and green tea, finding 98.50 % and 99.07 % inhibition, respectively. Overall, significantly (P < 0.05) higher amount of phenolic compounds as well as antioxidant activity were observed in green tea.

Cryopreservation Studies on Silver Carp (Hypophthalmichthys molitrix) Embryos

BACKGROUND

Cryopreservation is an effective tool for the preservation of live biological materials.

OBJECTIVE

This study examined the suitability of cryopreservation protocols and the effectiveness of ultrasound for silver carp embryos.

MATERIALS AND METHODS

Embryos at three developmental stages were exposed to 10, 15, 20, and 25% of five cryoprotectants (CPAs), namely propylene glycol (PG), dimethylformamide (DFA), DMSO, MeOH, and ethylene glycol (EG) for 20 min. Embryos were exposed to twelve vitrification solutions (VSs) for 10 (five steps of 2 min), 15 (five steps of 3 min), 20 (five steps of 4 min) min. Embryos were also exposed to ultrasound in VSs prior to cooling for cryopreservation.

RESULTS

Hatching rates decreased with increasing CPA concentrations while toxicity varied in the order of PG < DMSO < EG < MeOH < DFA. Tail elongation stage was more tolerant to CPA than 6-somites and morula stages. The survival of embryos exposed to ultrasound in VS was remarkably lower than in water. Embryos exposed to ultrasound in VSs under the best conditions did not response well after attempted vitrification.

CONCLUSION

Ultrasound-mediated CPA impregnation could be effective but other innovative methods may be needed to attain successful cryopreservation.

"Anterior interosseous nerve syndrome (Kiloh Nevin Syndrome) revealing Gantzer muscle and simultaneous myasthenia gravis"

There hasn't been a previous case report of the anterior interosseous nerve injury secondary to the presence of the muscle of Gantzer in a patient with myasthenia gravis in literature before. The anterior interosseous nerve compressive syndrome, also known as Kiloh-Nevin syndrome, is a rare disorder comprising less than 1% of all upper limb neuropathies. Establishing the etiology of anterior interosseous nerve compressive syndrome is challenging because of the lack of specific clinical findings or testing. Herein is the case of a 46 years-old male presented with left eye ptosis, ophthalmoparesis, diplopia, and right-hand weakness. On physical examination, the Pinch Grip test was positive. Electromyography studies showed neurogenic atrophy in the muscles innervated by the anterior interosseous nerve, as well as a pathological decrement of the muscle action potential of more than 10% on repetitive nerve stimulation. Concluding that the presence of the Gantzer muscle caused anterior interosseous nerve compressive syndrome was mainly a diagnosis of exclusion, after careful consideration of other possible etiologies including carpal tunnel syndrome, cervical radiculopathy, and Parsonage-Turner Syndrome. Even though anterior interosseous nerve compressive syndrome is very rare, clinical suspicion ought to arise in the presence of weak radial flexor digitorum profundus and flexor pollicis longus muscles. This case highlights the importance of a thorough medical history, a meticulous physical examination, and particularly the significance of electromyography studies in diagnosing different neuropathological entities. When appropriate, these steps offer information crucial to the differential diagnosis and eventual surgical management, assisting physicians in making informed and accurate treatment decisions.

The Role of National Specialist Societies in Influencing Transformational Change in Low-Middle Income Countries - Reflections on the Model of Implementation for a National Endoscopy Training Programme in Bangladesh

The British Society of Gastroenterology (BSG) and the Bangladesh Gastroenterology Society (BGS) have collaborated on an endoscopy training programme, which has grown up over the past decade from a small scheme borne out of the ideas of consultant gastroenterologists in Swansea, South Wales (United Kingdom) to improve gastroenterology services in Bangladesh to become a formalised training programme with broad reach. In this article, we document the socioeconomic and historical problems that beset Bangladesh, the current training needs of doctors and how the BSG-BGS collaboration has made inroads into changing outcomes both for gastroenterologists in Bangladesh, but also for the populations they serve.

Mental Health of the COVID-19 Patients in Bangladesh

The mental health aspect of coronavirus disease-19 (COVID-19) patients in Bangladesh has remained less focused and has not been addressed properly. The objective of the study was to assess the levels of anxiety and depression in COVID-19 patients. We adopted a mixed online and telephone-based survey using Google Forms. Recruitment was performed through a snowball sampling approach. The Google Form was initially circulated in Facebook to identify interested participants. Then, three trained physicians interviewed the online responders over telephone for a period spanning from April 2020 to June 2020. Two well-known questionnaires, the Generalized Anxiety Disorder 7-item (GAD-7) scale and the Patient Health Questionnaire (PHQ-9), were used for the assessment of anxiety and depression, respectively. Here, the severity of anxiety was classified with the standard thresholds: minimal or none (0-4), mild (5-9), moderate (10-14) and severe (>15) for the GAD-7. Depression severity score: 0-4 was considered as none or no depression, 5-9: mild, 10-14: moderate, 15-19: moderately severe, 20-27 was for severe depression. A total of 237 patients were finally analyzed. The mean age ±SD of the patients was 41.59±13.73 years. Most of them were male (73%) and lived in urban areas (90.29%). Half of the patients were unemployed, and 17.7% admitted loss of job due to lockdown. The overall prevalence of anxiety and depression was 55.7% and 87.3%, respectively. The mean GAD-7 score was 5.79±4.95, and the mean PHQ-9 score was 5.64±5.15. Among the depressive patients, 3% had minimal depression, 38.4% had mild depression, 32.1% had moderate depression, 11.8% had moderate depression, and 2.1% had a severe depression. Similarly, 37.1%, 10.5% and 8% had mild, moderate and severe levels of anxiety, respectively. Nearly half of the study population (47.7%) was suffering from both depression and anxiety. Living in urban area was an independent predictor for depression (OR 3.882; CI: 1.249-12.069). Considering the high comorbid burden, the mental health issues of these patients need to be addressed and reinforced to the existing health system on a priority basis.
