    Background: Trans-radial percutaneous coronary intervention (PCI) in cardiac procedures accesses coronary arteries through the wrist's radial artery. Post-PCI, hemostatic compression on the radial artery prevents bleeding and aids healing. Radial artery occlusion (RAO), a possible complication, involves blockage of the radial artery. This study aimed to assess the relationship between radial artery occlusion after trans-radial percutaneous coronary intervention with the duration of hemostatic compression. Methods: This prospective observational study was conducted in the Department of Cardiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, spanning from September 2018 to August 2019. The study enrolled 140 patients who underwent percutaneous coronary intervention (PCI) through the trans-radial approach (TRA), randomly assigned to two groups: Group I (2-hour hemostatic compression after PCI) and Group II (6-hour hemostatic compression post-procedure). Data analysis was performed using SPSS version 23.0. Results: In this study, early radial artery occlusion was observed in 4.3% of patients in group I and 12.8% in group II (P=0.04), while late radial artery occlusion occurred in 2.8% of patients in group I and 11.4% in group II, with a statistically significant difference (P=0.04). Multivariate logistic regression analysis identified a 6-hour hemostatic compression duration (P=0.01), post-procedural nitroglycerine use (P=0.03), and procedure time (P=0.03) as predictors of radial artery occlusion. Conclusions: Reduced hemostatic compression duration is linked to a decreased occurrence of both early and late radial artery occlusion following trans-radial intervention

    Background: Gestational diabetes mellitus is defined as diabetes diagnosed during pregnancy that is not clearly overt diabetes. GDM has many adverse consequences on the health of mother and fetus. Methods: This cohort study was carried out involving 77 women of 11 to14-week pregnant attending in the Gynecology & Obstetrics and Fetomaternal Medicine OPD, BSMMU from September 2020 to August 2021. Results: Respondents were divided into two groups. Low PAPP-A group (<0.5MoM) and normal PAPP-A group (>0.5MoM). In low PAPP-A group, out of 16 respondents, 8 (42.1%) developed GDM and remaining 8(13.8%) were euglycemic. Whereas, in normal PAPP-A group, out of 61 respondents, majority 50 (86.2%) were euglycemic and only 11 (57.9%) women developed GDM. A total 19 (24.68%) respondents developed GDM from both low and normal PAPP-A group. ROC analysis of PAPP-A level for detection of GDM, a AUC value of 0.889 (95% CI 0.818-0.960) found which was statistically significant. A cut off value of ≤16.80 showed the highest Youden index (0.652) with 89.4% sensitivity and 81% specificity, the accuracy was 83.35. Moreover, a cut off value ≤16.80 showed PPV and NPV of 62.1% and 95.9%, respectively. PAPP-A level of GDM detected (10.32±5.56) µg/ml was significantly lower from non GDM mothers (25.08 ±9.85) µg/ml, where p<0. 001. Conclusions: Study finding revealed that maternal serum PAPP-A level was lower in 11-14 weeks of pregnancy who subsequently developed GDM. So, a low PAPP-A level (<0.5 MoM) in 11-14 weeks of pregnancy is associated for development of GDM

    Measuring Coverage in MNCH:A Prospective Validation Study in Pakistan and Bangladesh on Measuring Correct Treatment of Childhood Pneumonia

    Antibiotic treatment for pneumonia as measured by Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) is a key indicator for tracking progress in achieving Millennium Development Goal 4. Concerns about the validity of this indicator led us to perform an evaluation in urban and rural settings in Pakistan and Bangladesh.Caregivers of 950 children under 5 y with pneumonia and 980 with "no pneumonia" were identified in urban and rural settings and allocated for DHS/MICS questions 2 or 4 wk later. Study physicians assigned a diagnosis of pneumonia as reference standard; the predictive ability of DHS/MICS questions and additional measurement tools to identify pneumonia versus non-pneumonia cases was evaluated. Results at both sites showed suboptimal discriminative power, with no difference between 2- or 4-wk recall. Individual patterns of sensitivity and specificity varied substantially across study sites (sensitivity 66.9% and 45.5%, and specificity 68.8% and 69.5%, for DHS in Pakistan and Bangladesh, respectively). Prescribed antibiotics for pneumonia were correctly recalled by about two-thirds of caregivers using DHS questions, increasing to 72% and 82% in Pakistan and Bangladesh, respectively, using a drug chart and detailed enquiry.Monitoring antibiotic treatment of pneumonia is essential for national and global programs. Current (DHS/MICS questions) and proposed new (video and pneumonia score) methods of identifying pneumonia based on maternal recall discriminate poorly between pneumonia and children with cough. Furthermore, these methods have a low yield to identify children who have true pneumonia. Reported antibiotic treatment rates among these children are therefore not a valid proxy indicator of pneumonia treatment rates. These results have important implications for program monitoring and suggest that data in its current format from DHS/MICS surveys should not be used for the purpose of monitoring antibiotic treatment rates in children with pneumonia at the present time

    Get PDF
    ‘EBVM Learning’ is a freely available resource created in 2015 by an international team with the support of RCVS Knowledge. The resource comprises a series of online modules teaching the fundamental concepts of evidence-based veterinary medicine (EBVM) (Ask, Acquire, Appraise, Apply & Assess) supported by case studies, exercises, worked examples and quizzes. The aim of the current study (undertaken in 2019) was to review ‘EBVM Learning’ to ensure its ongoing relevance and usefulness to the range of learners engaged in EBVM. Feedback was gathered from stakeholder groups using website statistics and feedback forms, a survey and semi-structured interviews to provide a combination of quantitative and qualitative data.Website statistics revealed an international audience and a steady increase in visitors exceeding 1,000 per month in August 2020. Feedback via the online form (n=35) and survey (n=71) indicated that the resource was well structured, with an appropriate level and amount of content, useful examples and quizzes and the majority of respondents would use it again. Semi-structured interviews of educators (n=5) and veterinarians (n=8) identified three themes: features of the ‘EBVM Learning’ resource (strengths, suggestions for improvement), embedding the resource in education (undergraduate, postgraduate) and promoting EBVM (challenges, motivation for engagement). At a project team workshop the results were used to plan updates to the existing content and to identify new ways to promote learning and engagement. An updated version of ‘EBVM Learning’ was developed.‘EBVM Learning’ is helping to produce the next generation of evidence-based practitioners and enabling to engage in the concepts of EBVM as part of their clinical practice

    Introduction: Copy number variations (CNVs) play a critical role in the pathogenesis of neurodevelopmental disorders (NDD) among children. In this study, we aim to identify clinically relevant CNVs, genes and their phenotypic characteristics in an ethnically underrepresented homogenous population of Bangladesh. Methods: We have conducted chromosomal microarray analysis (CMA) for 212 NDD patients with male to female ratio of 2.2:1.0 to identify rare CNVs. To identify candidate genes within the rare CNVs, gene constraint metrics [i.e., “Critical-Exon Genes (CEGs)”] were applied to the population data. Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) was followed in a subset of 95 NDD patients to assess the severity of autism and all statistical tests were performed using the R package. Results: Of all the samples assayed, 12.26% (26/212) and 57.08% (121/212) patients carried pathogenic and variant of uncertain significance (VOUS) CNVs, respectively. While 2.83% (6/212) patients’ pathogenic CNVs were found to be located in the subtelomeric regions. Further burden test identified females are significant carriers of pathogenic CNVs compared to males (OR = 4.2; p = 0.0007). We have observed an increased number of Loss of heterozygosity (LOH) within cases with 23.85% (26/109) consanguineous parents. Our analyses on imprinting genes show, 36 LOH variants disrupting 69 unique imprinted genes and classified these variants as VOUS. ADOS-2 subset shows severe social communication deficit (p = 0.014) and overall ASD symptoms severity (p = 0.026) among the patients carrying duplication CNV compared to the CNV negative group. Candidate gene analysis identified 153 unique CEGs in pathogenic CNVs and 31 in VOUS. Of the unique genes, 18 genes were found to be in smaller (<1 MB) focal CNVs in our NDD cohort and we identified PSMC3 gene as a strong candidate gene for Autism Spectrum Disorder (ASD). Moreover, we hypothesized that KMT2B gene duplication might be associated with intellectual disability. Conclusion: Our results show the utility of CMA for precise genetic diagnosis and its integration into the diagnosis, therapy and management of NDD patients

    Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats

    In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security

    Robust Extended H∞ Control Strategy Using Linear Matrix Inequality Approach for Islanded Microgrid

    Get PDF
    This paper presents the design of an extended parameterisations of H∞ controller for off grid operation of a microgrid. The microgrid consists of distributed generation units, filters and local loads. The filters are used to achieve accurate sinusoidal output voltage. However, loads which are connected to the microgrid are parametrically uncertain. Hence, it undergoes with unknown loads uncertainties. These unknown loads may create unknown loads harmonics, non-linearities which may reduce the voltage and current profile of the microgrid. As a result, the sudden rise and fall of voltage current profile damages the domestic and commercial loads. The proposed controller provides robust stability against various unknown loads and uncertainties. The design of the controller is presented using linear matrix inequality approach and satisfies the Lyapunov stability criterion. Moreover, it provides lower closed-loop H∞ norm and has better tracking accuracy than other. For justification, several load conditions have been tested in MATLAB/SimPowerSystem Toolbox to ensure the robust stability of the proposed controller. All the results presented in the paper indicate high performance of the controller

    Investigating water productivity and yield of boro rice under conventional and conservation irrigation practices in Bangladesh

    No full text
    Irrigation is one of the vital inputs to rice production in Bangladesh, where 78% of irrigation is dependent on groundwater (GW) resources. For the past two decades, GW level has been significantly declining across the country and on the other hand, surface water is limited in the dry season. This poses a great challenge to meet burgeoning irrigation demand of the country. Amid this situation, optimal and judicial use of water for irrigation is being thought to be a way out without compromising crop yield. In such context, an experiment was performed at the Field Irrigation Laboratory, Bangladesh Agricultural University in Mymensing to investigate the water productiv- ity, growth and yield characteristics of BRRI dhan28 under three different irrigation techniques i.e. alternate wetting and drying (AWD), raised bed (RB), and conventional continuous flooding (CF). Six treatments including four AWD variants with three replications for each treatment were laid out randomly in 18 plots. The highest yield was 6.63±0.65 t ha&#8722;1 under 10 cm disappearance AWD treatment (T2). But the lowest yield was (5.73±1.25 t ha&#8722;1) under mixed AWD treatment (T5) which did not show a significant variation on the yield of different techniques. CF treatment (T1) needed 68.94±3.44 cm of water and its water productivity was 0.48±0.08 kg m&#8722;3, where the T2 treatment needed average 52.10±3.21 cm of water and average water productivity was 0.59±0.04 kg m&#8722;3. The study revealed that 10 cm, 15 cm, 20 cm disappearance AWD and mixed AWD treatments (respectively, T2, T3, T4, and T5) saved 24.42, 24.28, 28.92 and 38.56% of irrigation water, respectively, and where the RB also saved 15.52% over the conventional method. On the basis of the above consideration, it can be concluded that AWD technology can be adopted to increase the water productivity of dry season boro rice and thus to make its cultivation more profitable.
