First Measurement of Antideuteron Number Fluctuations at Energies Available at the Large Hadron Collider. PHYSICAL REVIEW LETTERS 2023; 131:041901. [PMID: 37566856 DOI: 10.1103/physrevlett.131.041901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 07/01/2022] [Accepted: 09/15/2022] [Indexed: 08/13/2023]
Abstract
The first measurement of event-by-event antideuteron number fluctuations in high energy heavy-ion collisions is presented. The measurements are carried out at midrapidity (|η|<0.8) as a function of collision centrality in Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV using the ALICE detector. A significant negative correlation between the produced antiprotons and antideuterons is observed in all collision centralities. The results are compared with a state-of-the-art coalescence calculation. While it describes the ratio of higher order cumulants of the antideuteron multiplicity distribution, it fails to describe quantitatively the magnitude of the correlation between antiproton and antideuteron production. On the other hand, thermal-statistical model calculations describe all the measured observables within uncertainties only for correlation volumes that are different with respect to those describing proton yields and a similar measurement of net-proton number fluctuations.

Enhanced Deuteron Coalescence Probability in Jets. PHYSICAL REVIEW LETTERS 2023; 131:042301. [PMID: 37566840 DOI: 10.1103/physrevlett.131.042301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 04/07/2023] [Accepted: 06/05/2023] [Indexed: 08/13/2023]
Abstract
The transverse-momentum (p_{T}) spectra and coalescence parameters B_{2} of (anti)deuterons are measured in p-p collisions at sqrt[s]=13 TeV for the first time in and out of jets. In this measurement, the direction of the leading particle with the highest p_{T} in the event (p_{T}^{lead}>5 GeV/c) is used as an approximation for the jet axis. The event is consequently divided into three azimuthal regions, and the jet signal is obtained as the difference between the toward region, that contains jet fragmentation products in addition to the underlying event (UE), and the transverse region, which is dominated by the UE. The coalescence parameter in the jet is found to be approximately a factor of 10 larger than that in the underlying event. This experimental observation is consistent with the coalescence picture and can be attributed to the smaller average phase-space distance between nucleons in the jet cone as compared with the underlying event. The results presented in this Letter are compared to predictions from a simple nucleon coalescence model, where the phase-space distributions of nucleons are generated using pythia8 with the Monash 2013 tuning, and to predictions from a deuteron production model based on ordinary nuclear reactions with parametrized energy-dependent cross sections tuned on data. The latter model is implemented in pythia8.3. Both models reproduce the observed large difference between in-jet and out-of-jet coalescence parameters, although the almost flat trend of the B_{2}^{Jet} is not reproduced by the models, which instead give a decreasing trend.

Monitoring SARS-CoV-2 variants in wastewater of Dhaka City, Bangladesh: approach to complement public health surveillance systems. Hum Genomics 2023; 17:58. [PMID: 37420264 PMCID: PMC10326934 DOI: 10.1186/s40246-023-00505-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 06/28/2023] [Indexed: 07/09/2023] Open
Abstract
BACKGROUND Wastewater-based epidemiological surveillance has been considered a powerful tool for early detection and monitoring of the dynamics of SARS-CoV-2 and its lineages circulating in a community. This study is aimed to investigate the complexity of SARS-CoV-2 infection dynamics in Dhaka city by examining its genetic variants in wastewater. Also, the study seeks to determine a connection between the SARS-CoV-2 variations detected in clinical testing and those found in wastewater samples. RESULTS Out of 504 samples tested in RT-qPCR, 185 (36.7%) tested positive for SARS-CoV-2 viral RNA. The median log10 concentration of SARS-CoV-2 N gene copies/Liter of wastewater (gc/L) was 5.2, and the median log10 concentration of ORF1ab was 4.9. To further reveal the genetic diversity of SARS-CoV-2, ten samples with ORF1ab real-time RT-PCR cycle threshold (Ct) values ranging from 28.78 to 32.13 were subjected to whole genome sequencing using nanopore technology. According to clade classification, sequences from wastewater samples were grouped into 4 clades: 20A, 20B, 21A, 21J, and the Pango lineage, B.1, B.1.1, B.1.1.25, and B.1.617.2, with coverage ranging from 94.2 to 99.8%. Of them, 70% belonged to clade 20B, followed by 10% to clade 20A, 21A, and 21J. Lineage B.1.1.25 was predominant in Bangladesh and phylogenetically related to the sequences from India, the USA, Canada, the UK, and Italy. The Delta variant (B.1.617.2) was first identified in clinical samples at the beginning of May 2021. In contrast, we found that it was circulating in the community and was detected in wastewater in September 2020. CONCLUSION Environmental surveillance is useful for monitoring temporal and spatial trends of existing and emerging infectious diseases and supports evidence-based public health measures. The findings of this study supported the use of wastewater-based epidemiology and provided the baseline data for the dynamics of SARS-CoV-2 variants in the wastewater environment in Dhaka, Bangladesh.

Abstract
Having the first bone to ossify clavicle is a bone of pectoral girdle. It is the only bony attachment between the trunk and upper limb. To obtain the precise data that is required to investigate the range in size and morphological features of the human clavicle, a study was undertaken on dry human clavicles which had been sourced from the Department of Anatomy. The purpose for undertaking this study was to obtain baseline data on the clavicular bow in the transverse plane. This cross-sectional descriptive study having some analytical components was done among 150 (65 right and 85 left) fully ossified dry clavicles in Mymensingh Medical College, Bangladesh from January 2020 to December 2020. Sample which met the inclusion criteria was collected through non random sampling technique, from Anatomy department of Mymensingh Medical College and Community Based Medical College Bangladesh. The parameters (the depth of medial and lateral curvatures) were measured with the help of rigid osteometry board and were expressed in millimeter. In the current study, the mean±SD depth of medial curvature of 65 clavicles of right side was 15.54±3.54mm and 15.45±3.24mm of 85 left clavicles. The mean±SD depth of lateral curvature of right side was 11.71±2.54mm and of left side was 9.21±2.31mm. Correlation was done in between depth of medial and lateral curvatures on both sides and the regression line showed positive correlation but these differences were statistically non-significant on both sides.

Abstract
This study tried to understand the impact that hypertension, coronary heart diseases and diabetes can have on the intensity of coronavirus within the human body. This study was conducted using a systematic review process where secondary data have been collected from 10 previously published research papers. Most of the individuals contracting COVID-19 are also suffering from diabetes, cardiovascular diseases and hypertension. The studies used to carry out this systematic review have exhibited a pattern that indicates a strong correlation. That being said, because of the possibility of extraneous variables, most of the studies at this point have significant drawbacks. Many of such variables for example, smoking behavior or level of fitness have not been considered while selecting sample for most of the studies. Therefore, more highly targeted studies need to be carried out for understanding this disease and the long- and short-term impact it can have.

Abstract
Varicose veins are part of the spectrum of chronic venous disease and include spider telangiectasias, reticular veins, and true varicosities. It may present without advanced signs of chronic venous insufficiency. Sclerotherapy is a treatment choice for patients with varicose veins of lower extremity; it uses the intravenous injection of chemical drugs to achieve the goal of inflammatory occlusion. Phlebectomy, a minimally invasive procedure usually used for higher diameter of varicose veins at the surface of the skin. Objective of the study was to compare the outcome of Phlebectomy and Sclerotherapy in varicose vein patients. It was a quasi experimental study was conducted in the Department of Vascular Surgery in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of June 2019 to May 2020. Patients admitted with varicose vein and varicosity of the lower limbs with valves and perforator incompetence in the Department of Vascular Surgery, BSMMU, Dhaka, Bangladesh. During this period 60 patients were selected purposive randomly. Patients were divided to 30 patients were treated with Phlebectomy (Group I) 30 patients were treated with Sclerotherapy (Group II). Data were collected according to the pre-designed semi-structured data collection sheet. After editing data analysis were carried out by using the Statistical Package for Social Science (SPSS) version 22.0 Windows software. This study shows average age 40.73±15.50 years in Phlebectomy (Group I) and 38.43±11.08 years in Sclerotherapy (Group II). Males are more commonly involved than females between two groups which was 76.7% in Phlebectomy (Group I) and 70.0% in Sclerotherapy (Group II). The change CEAP improved to 93.3% in patients who underwent phlebectomy when compared to 83.3% in patients who underwent sclerotherapy. During the follow-up with duplex at treated veins showed 93.3% complete occlusion of treated veins in the phlebectomy group, while only 70.0% of the patients in the sclerotherapy group showed evidence of complete occlusion. In phlebectomy group recurrence of leg varicosities were found 6.7% of the patients, while 26.7% of the patients in the sclerotherapy group. The difference was statistically significant between two groups (p=0.038). This study shows phlebectomy to be much better option than sclerotherapy for the treatment of varicose veins and hence can be used routinely. Both phlebectomy and sclerotherapy not only revealed minimal time taken for return to normal activity but also proved to be safer with regard to complications.

Abstract
Despite recent advances in neonatal care, early detection of neonatal sepsis still remains challenging. Positive blood culture is the gold standard for definitive diagnosis of neonatal sepsis but is time consuming and demands a well equipped laboratory setting. Therefore, it becomes imperative to evaluate usefulness of white blood cell count, Immature to total (IT) ratio and C-reactive protein as potential markers in the early diagnosis of neonatal sepsis. The objective of the study was to evaluate role of white blood cell count, IT ratio and C-reactive protein in early detection of clinically suspected neonatal sepsis. This cross-sectional descriptive study was conducted from January 2017 to December 2018 at Special Care Newborn Unit (SCANU) of Rangpur Medical College Hospital, Rangpur, Bangladesh. After parental permission and ethical clearance, a total of 70 eligible neonates were included into the study. Estimation of total white blood cell count, IT ratio and C-reactive protein as well as blood culture were done for each case. Significance for Chi-Square test and Pearson's correlation coefficient test was predetermined as p<0.05. Of the total 70 neonates studied, 19(27.14%) were blood culture positive and most common organism was Escherichia coli (7/14, 37.0%). Among individual and combination tests, CRP was highly sensitive (100%) followed by WBC count (74.94%). Highly specific tests in diagnosing sepsis were combination test of IT ratio and CRP (88.23%) followed by combination test of WBC count and CRP (82.35%). Positive predictive value (PPV) was high for combination test of WBC count and CRP (90.90%) followed by combination test of IT ratio and CRP (90.47%). Negative predictive value (NPV) was high in CRP (100.0%) followed by WBC count (89.19%). IT ratio positively correlated with CRP (p=0.002) and there was significant association between raised CRP and WBC count (p=0.005) in neonatal sepsis. Diagnostic role of both individual and combination tests were significant in early detection of clinically suspected neonatal sepsis while awaiting results of blood culture. However, none of the combination tests were able to achieve 100.0% sensitivity.

Abstract
Legg-Calve-Perthes disease (LCPD) that starts after 8 years (late onset) usually follow more aggressive course and the long-term outcome is also poor. Treatment method of LCPD that will produce best results is controversial particularly if the patients are with late-onset presentation. This prospective study was conducted from January 2015 to January 2019 at Dhaka Medical College Hospital and Health N Hope Hospital, Dhaka, Bangladesh. We evaluated the radiographic outcomes for patients who had varus derotation femoral osteotomy (VDRO). We followed up 16 patients who had femoral varus osteotomy. All patients were above 8 years of age at clinical onset. The involvement of femoral epiphysis was in either in B or B/C in lateral pillar classification. All patients had MRI done to confirm radiological diagnosis and classification. The mean age was 9.5 years (range, 8 to 12 years). Final outcome was evaluated by using the Stulberg classification which was radiological. Important exclusion criteria were patient with bilateral involvement and requirement of femoral varus >30 degree. We had 81.25% of our patient with satisfactory outcomes. Among them there were Stulberg grade I, 0 cases; Stulberg grade II, 13 cases (81.25%); Stulberg III, 3 cases (18.75%), Stulberg IV and V both 0 case each. The surgical outcomes for varus derotation femoral osteotomy in late onset LCPD patients over 8 years old were showing the good results than other modalities of non surgical and surgical methods.

Abstract
High blood pressure is a major risk factor for premature death. Leisure-time physical activities have been recommended to control hypertension. Studies examining how leisure-time physical activity affects blood pressure have found mixed results. We aimed to conduct a systematic review examining the effect of leisure-time physical activity (LTPA) on lowering blood pressure among adults living with hypertension. We searched studies in Embase, Medline/PubMed, Web of Science, Physical Education Index, Scopus and CENTRAL (the Cochrane Library). The primary outcome variables were systolic blood pressure (SBP) and diastolic blood pressure (DBP). This systematic review is registered on PROSPERO (CRD42021260751). We included 17 studies out of 12,046 screened articles in this review. Moderate-intensity LTPA (all types) reduced SBP compared to the non-intervention control group (MD -5.35 mm Hg, 95% CI -8.06 to -2.65, nine trials, n = 531, low certainty of the evidence). Mean DBP was reduced by -4.76 mm Hg (95% CI -8.35 to -1.17, nine trials, n = 531, low certainty of the evidence) in all types of LTPA (moderate intensity) group compared to the non-intervention control group. Leisure-time walking reduced mean SBP by -8.36 mmHg, 95% CI -13.39 to -3.32, three trials, n = 128, low certainty of the evidence). Walking during leisure time reduced -5.03 mmHg mean DBP, 95% CI -8.23 to -1.84, three trials, n = 128, low certainty of the evidence). Performing physical activity during free time probably reduces SBP and DBP (low certainty of the evidence) among adults with hypertension.

Abstract
Background The next-generation sequencing (NGS) technology facilitates in-depth study of host-pathogen metatranscriptome. We, therefore, implicated phylodynamic and transcriptomic approaches through NGS technology to know/understand the dengue virus (DENV) origin and host response with dengue fever. Methods In this study, blood serum RNA was extracted from 21 dengue patients and 3 healthy individuals. Total transcriptomic data were analyzed for phylogenetic, phylodynamic, differential express gene (DEG), and gene ontology (GO) using respective bioinformatics tools. Results The viral genome sequence revealed dengue viral genome size ranges 10647 to 10707 nucleotide. Phylogenetic and phylodynamic analysis showed that the 2021 epidemic isolates were DENV-3 genotype-I and maintained as a new clade in compared to 2019 epidemic. Transcriptome analysis showed a total of 2686 genes were DEG in dengue patients compared to control with a q-value < 0.05. DESeq2 plot counts function of the top 24 genes with the smallest q-values of differential gene expression of RNA-seq data showed that 11 genes were upregulated, whereas 13 genes were downregulated. GO analysis showed a significant upregulation (p = < 0.001) in a process of multicellular organismal, nervous system, sensory perception of chemical stimulus, and G protein-coupled receptor signaling pathways in the dengue patients. However, there were a significant downregulation (p = < 0.001) of intracellular component, cellular anatomical entity, and protein-containing complex in dengue patients. Most importantly, there was a significant increase of a class of immunoregulatory proteins in dengue patients in compared to the controls, with increased GO of immune system process. In addition, upregulation of toll receptor (TLR) signaling pathways were found in dengue patients. These TLR pathways were particularly involved for the activation of innate system coupled with adaptive immune system that probably involved the rapid elimination of dengue virus infected cells. These differentially expressed genes could be further investigated for target based prophylactic interventions for dengue. Conclusion This is a first report describing DENV complete genomic features and differentially expressed genes in patients in Bangladesh. These genes may have diagnostic and therapeutic values for dengue infection. Continual genomic surveillance is required to further investigate the shift in dominant genotypes in relation to viral pathogenesis.

Abstract
We performed a pressure-driven study of zinc pyrovanadate, Zn2V2O7, using the first-principles approach under the framework of density functional theory (DFT). Zn2V2O7 crystalizes in a monoclinic (α-phase) structure with the space group C2/c at ambient pressure. In comparison with the ambient phase, there are four different high-pressure phases, namely β, γ, κ and δ, found at 0.7, 3.8, 4.8 and 5.3 GPa, respectively. The detailed crystallographic analysis as well as their structures is consistent with the theory and experiment reported in the literature. All phases including the ambient phase are mechanically stable, elastically anisotropic and malleable. The compressibility of the studied pyrovanadate is higher than that of the other meta- and pyrovanadates. The energy dispersion of these studied phases reveals that they are indirect band gap semiconductors with wide band gap energies. The band gap energies follow a reduced trend with pressure except the κ-phase. The effective masses for all of these studied phases were computed from their corresponding band structures. The values of energy gaps obtained from the band structures are almost similar to the optical band gap obtained from the optical absorption spectra, as estimated by the Wood-Tauc theory.

Abstract
BACKGROUND: Evidence of the effectiveness of the WHO-recommended design of longer individualized regimens for multidrug- or rifampicin-resistant TB (MDR/RR-TB) is limited.OBJECTIVES: To report end-of-treatment outcomes for MDR/RR-TB patients from a 2015-2018 multi-country cohort that received a regimen consistent with current 2022 WHO updated recommendations and describe the complexities of comparing regimens.METHODS: We analyzed a subset of participants from the endTB Observational Study who initiated a longer MDR/RR-TB regimen that was consistent with subsequent 2022 WHO guidance on regimen design for longer treatments. We excluded individuals who received an injectable agent or who received fewer than four likely effective drugs.RESULTS: Of the 759 participants analyzed, 607 (80.0%, 95% CI 77.0-82.7) experienced successful end-of-treatment outcomes. The frequency of success was high across groups, whether stratified on number of Group A drugs or fluoroquinolone resistance, and ranged from 72.1% to 90.0%. Regimens were highly variable regarding composition and the duration of individual drugs.CONCLUSIONS: Longer, all-oral, individualized regimens that were consistent with 2022 WHO guidance on regimen design had high frequencies of treatment success. Heterogeneous regimen compositions and drug durations precluded meaningful comparisons. Future research should examine which combinations of drugs maximize safety/tolerability and effectiveness.

Abstract
In the present study, we determined the developmental toxicity of endosulfan at an elevated ambient temperature using the zebrafish animal model. Zebrafish embryos of various developmental stages were exposed to endosulfan through E3 medium, raised under two selected temperature conditions (28.5 °C and an elevated temperature of 35 °C), and monitored under the microscope. Zebrafish embryos of very early developmental stages (cellular cleavage stages, such as the 64-cell stage) were highly sensitive to the elevated temperature as 37.5% died and 47.5% developed into amorphous type, while only 15.0% of embryos developed as normal embryos without malformation. Zebrafish embryos that were exposed concurrently to endosulfan and an elevated temperature showed stronger developmental defects (arrested epiboly progress, shortened body length, curved trunk) compared to the embryos exposed to either endosulfan or an elevated temperature. The brain structure of the embryos that concurrently were exposed to the elevated temperature and endosulfan was either incompletely developed or malformed. Furthermore, the stress-implicated genes hsp70, p16, and smp30 regulations were synergistically affected by endosulfan treatment under the elevated thermal condition. Overall, the elevated ambient temperature synergistically enhanced the developmental toxicity of endosulfan in zebrafish embryos.

Abstract
Time-resolved fluorescence anisotropy (FA) uses the fluorophore depolarization rate to report on rotational diffusion, conformation changes, and intermolecular interactions in solution. Although FA is a rapid, sensitive, and nondestructive tool for biomolecular interaction studies, the short (∼ns) fluorescence lifetime of typical dyes largely prevents the application of FA on larger macromolecular species and complexes. By using triplet shelving and recovery of optical excitation, we introduce optically activated delayed fluorescence anisotropy (OADFA) measurements using sequential two-photon excitation, effectively stretching fluorescence anisotropy measurement times from the nanosecond scale to hundreds of microseconds. We demonstrate this scheme for measuring slow depolarization processes of large macromolecular complexes, derive a quantitative rate model, and perform Monte Carlo simulations to describe the depolarization process of OADFA at the molecular level. This setup has great potential to enable future biomacromolecular and colloidal studies.

Abstract
BACKGROUND MicroRNAs (miRNAs) are small endogenous RNAs with an approximate length of 18-22 nucleotides and involved in the regulation of gene expression in transcriptional or post-transcriptional levels. They were found to be associated with leaf morphogenesis, flowering time, vegetative phase change, and response to environmental cues in plants, where they act as a critical regulatory factor. The nature of high conservancy of plant miRNAs within the plant species made it possible to detect the conserved miRNAs by computational approaches. Expressed Sequence Tags (EST) based comparative genomic approaches provide advantages over wet lab approaches as it is convenient, easy to carry out and less time consuming. EST-based in silico approach can unravel new conserved miRNAs in plants, even when the complete genome sequence is not available. RESULTS To identify the novel miRNAs, a total of 46,865 ESTs from Jatropha curcas were searched for homology to all available 6746 mature miRNAs of plant eudicotyledons. Finally, we ended up with 12 novel miRNAs in Jatropha that range from 18 to 19 nucleotides where their respective precursor miRNAs had 54.11-71.76% (A + U) content. The putative miRNAs belong to 12 individual miRNA family and most of them have higher (A + U) content ranging from 47.36 to 77.77% than their respective miRNA homologs. Many of the target genes by the newly identified miRNAs were associated with plant growth and development, stress response, defense and hormone signaling, and oil synthesis pathways. CONCLUSION These findings have the potential to speed up miRNA identification and expand our understanding of miRNA functions in J. curcas.

Abstract
Giant cell tumor of tendon sheath arises from the synovium of tendon sheaths, joints, or bursa, mostly affects adults between 30 and 50 years of age, and is slightly more common in females. It corresponds to a localized form of pigmented villonodular synovitis (PVNS). Typically occur in the hand where they represent the second most common type of soft tissue tumors after synovial ganglions. Bilateral giant cell tumor of tendon sheath of tendoachilles is a rare presentation. We report the case of a 22-years-old female presenting with pain in both ankles without any history of trauma. On clinical examination, tenderness on both tendoachilles and local indurations were observed. Ultrasonography showed focal thickening of Achilles tendon bilaterally, and Doppler demonstrated increased flow in peritendinous area. MRI findings showed that most of the tumor had intermediate signal intensity and portions of the tumor had low signal intensity. Fine needle aspiration cytology confirmed the diagnosis of giant cell tumor of tendon sheath. Excision biopsy was done with no recurrence on subsequent follow-up.

Abstract
OBJECTIVES Understanding the knowledge, attitudes and practices (KAP) of COVID-19 within distinct populations may aid further public health messaging. This study's aims were to explore KAP towards COVID-19 in rural Bangladesh and identify any potential links to sociodemographics, existing clinical conditions and sources of information. DESIGN Cross-sectional community-based study. SETTING Participants were recruited from 18 villages using multistage cluster random sampling. METHODS Data were collected through face-to-face interviews, from June to November 2021, using a structured questionnaire. Data included sociodemographics, clinical conditions, sources of information and KAP of COVID-19 questions. Χ2 test, multiple logistic regression and correlation analyses were performed. RESULTS A total of 1603 participants were included with mean ages of 42.3±14.2 years, ranging from 18 to 60 years. Of these, 51% were male, 42.2% had secondary education and 45% had comorbidities. Television was the main source of COVID-19 information (55.8%). The overall correct response rate of KAP questions was 90%, 78% and 59%, respectively. In stepwise multiple logistic regression, good knowledge was associated with higher education (adjusted OR (AOR): 4.61, 95% CI: 2.40 to 8.85, p<0.001), employment, high body mass index (overweight and obese) and trust in the sources of information. Being female (AOR: 1.48, 95% CI: 1.19 to 1.85, p<0.001), having depression (AOR: 1.80, 95% CI: 1.34 to 2.43, p<0.001), being a past smoker and sources of information (family members/friends/relatives/neighbours) were associated with positive attitudes. Good practices were associated with older age (AOR: 1.52, 95% CI: 1.10 to 2.11, p=0.01), higher education (AOR: 2.78, 95% CI: 1.58 to 4.89, p<0.001) and having anxiety, while current smokers and fully vaccinated people were less likely to be engaged in good practices. Positive significant correlations between domains of KAP were observed as well as between past vaccination KAP and COVID-19 KAP. CONCLUSION This study uncovered gaps in understanding and practices, and identified targeted intervention especially for young and less educated people using mass media to promote updated knowledge regarding COVID-19 and the efficacy of preventive practices.

Abstract
OBJECTIVE The objective of this study was to evaluate the acceptance and uptake of COVID-19 vaccines in rural Bangladesh. DESIGN This was a cross-sectional study conducted between June and November 2021. SETTING This study was conducted in rural Bangladesh. PARTICIPANTS People older than 18 years of age, not pregnant and no history of surgery for the last 3 months were eligible to participate. PRIMARY AND SECONDARY OUTCOMES The primary outcomes were proportions of COVID-19 vaccine acceptance and roll-out participation among the rural population. The secondary outcome was identification of correlates which contributed to COVID-19 vaccine acceptance and roll-out participation. Χ2 tests and multivariable logistic regression analyses were performed to identify relevant correlates such as sociodemographic factors, clinical conditions and COVID-19-related factors. RESULTS A total of 1603 participants were enrolled. The overall COVID-19 vaccine acceptance was very high (1521/1601, 95%), and half of the participants received at least one dose of the COVID-19 vaccine. Majority of participants wanted to keep others safe (89%) and agreed to the benefits of COVID-19 vaccines (88%). To fulfil the requirement of online registration for the vaccine at the time, 62% of participants had to visit an internet café and only 31% downloaded the app. Over half (54%) of participants were unaware of countries they knew and trust to produce the COVID-19 vaccine. Increased age, being housewives, underweight and undergraduate education level were associated with vaccine acceptance, while being female, increased age and being overweight/obese were associated with vaccine uptake. Trust in the health department and practical knowledge regarding COVID-19 vaccines were positively associated with both vaccine acceptance and uptake. CONCLUSION This study found a very high COVID-19 vaccine acceptance in rural Bangladesh. Policymakers should support interventions aimed at increasing vaccine and general health literacy and ensure ongoing vaccine supply and improvement of infrastructure in rural areas.

Abstract
A general lockdown to minimize to slow transmission of COVID-19 in Bangladesh came into effect on March 26th and lasted until May 30th. The lockdown had far-reaching economic implications for the population, with many facing economic hardship due to loss of income. Despite the attempt of the government to ease economic hardship by means of social safety net packages, people suffered from poor access to health services, and financial and food insecurity. This is likely to have disastrous consequences for the nutritional status of young children. This cross-sectional study measured the impact of the first general lockdown on food consumption of young children, access to water, handwashing and health seeking behavior, and the ability to maintain livelihood among households with children under the age of 5, in rural Bangladesh. The result of the analysis suggest that loss of income was reported by almost all respondents across all socio-economic groups. However, the poorest households were less likely to provide for sufficient food for their families and had to reduce consumption of food. Diet diversity and food intake-particularly animal protein sources-for young children were severely affected. On the other, increased awareness of handwashing and access to soap were also reported. The pandemic is likely to be detrimental to the nutritional status of children in Bangladesh and can exacerbate existing health inequities. Strong social safety net programs are needed to protect vulnerable populations to consequences of restrictive measures, supported in design and implementation by non-governmental organizations.

Abstract
OBJECTIVES Preterm delivery (PD) is a worldwide health burden particularly in low-income and middle-income countries such as Bangladesh. It is a key indicator of neonatal mortality and a risk of morbidity in later life. This study aimed to determine the prevalence of PD and its associated factors among mothers in Northern region of Bangladesh. SETTING AND PARTICIPANTS Multistage sampling technique was used to select samples covering all the population from 9 Upazilas in Rajshahi district with 233 community clinics. A total of 540 mothers and their under-5 children were enrolled for the study. Descriptive statistics, χ2 test and logistic regression model were used to analyse the data. RESULTS Among all live births, the prevalence of PD was found to be 14.6%. Multiple binary logistic regression model suggested five factors of PD: (1) mothers who used contraceptive pill had lower chance of PD (p<0.05); (2) mothers with high fever during pregnancy period were more likely to have PD (p<0.05); (3) mothers who did not receive antenatal care service less than four times during pregnancy period had higher chance of PD (p<0.01); (4) mothers first married before 18 years who were more likely to have PD (p<0.01); (5) PD delivered mothers had more chance to get low birth weight children (p<0.05). In addition, unadjusted model demonstrated that mothers delivered first baby before their age<20 years were more risk to get PD (p<0.05). CONCLUSION Approximately one in seven infants was born preterm in our study area. Family planning method, number of antenatal care visit, mothers' age at marriage and high fever during pregnancy were the most important predictors of PD, these factors could be considered to reduce PD among Bangladeshi mothers. PD risk could be reduced by counselling and encouraging women to take antenatal care facilities from trained health providers.

Abstract
Stroke is not only the third leading cause of death in Bangladesh but it also causes a high number of disability adjusted life years loss (485 per 10,000 people). Appropriate treatment of recurrent stroke has to be established. Here we present A 60 year's old male patient with history of recurrent stroke who came in our out patient department. He had progressing bilateral middle cerebral artery atherosclerotic stenosis (100.0% on right side and 52.0% on left side) which was less severs but symptomatic at dominant hemisphere (left). Percutaneous transluminal angioplasty with stenting was done to prevent further ischemia and to increase the blood supply of remaining brain parenchyma. On post stenting follow-up patient did not suffered from any new event of stroke for about 22 months. Percutaneous transluminal angioplasty with stenting is an effective procedure to prevent recurrent stroke for intracranial atherosclerotic disease.

Abstract
Clavicle is an upper limb locomotory bone which helps in formation of pectoral girdle and connected the upper limb with axial skeleton. There is no baseline data of clavicle in contrast to demographic variation in our country, so the study was designed to obtain baseline data on clavicle for anthropological, forensic and clinical use. This descriptive cross-sectional study was done among 150 (65 right and 85 left) fully ossified dry human clavicle in Mymensingh Medical College, Mymensingh, Bangladesh from January 2020 to December 2020. Sample was collected by the help of nonrandom purposive sampling technique from Department of Anatomy of Mymensingh Medical College and Community Based Medical College, Bangladesh, Mymensingh. The parameters were the antero-posterior diameter and vertical diameter of sternal and acromial ends of clavicle, measured with the help of digital vernier slide caliper and expressed in millimeter. In the current study the mean±SD antero-posterior diameter of sternal end of 65 clavicles of right side was 21.97±2.889mm and 85 clavicles of left side were 20.30±3.459mm. The mean±SD antero-posterior diameter of acromial end of 65 right sided clavicles was 21.96±5.161mm and 85 clavicles of left side were 21.00±4.002mm. Correlation was done in between antero-posterior diameter and vertical diameter of sternal end of clavicle and the differences were highly significant on both sides. Similarly, when correlation was done for the acromial end of clavicle the difference was found non-significant on right side and highly significant on left side.

Abstract
Hypospadias is a developmental defect of male urethra characterized by absence of meatal opening at the tip of glans but is present at the ventral surface of penis anywhere along the shaft, even in the perineum. Usually this defect is associated with ventrally curved penis. Surgery is the single option to correct this birth defect. More than 300 techniques have been developed but none is universally acceptable as because, surgery is usually associated with fistula. Rate of fistula formation varies from technique to technique. Now a day, Snodgrass technique is widely practiced because of its low rate of fistula formation. Many factors are responsible for this post-operative complication. Most important one is developmentally defective ventral penile skin where some local factors like vascular and collagen tissues are insufficient. This observational study was performed to evaluate the role of dorsal vascular flap over the neourethra following urethroplasty by Snodgrass technique in terms of post-operative fistula formation in the Department of Paediatric Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from March 2018 to March 2020. A total of 39 patients with distal penile hypospadias were included in this study. All underwent Snodgrass urethroplasty with additional dorsal vascular flap over the neourethra to support this ventrally deficient local factor. The outcome in terms of post operative urethrocutaneous fistula was evaluated. Only two patients (5.15%) developed urethrocutaneous fistula. In conclusion, addition of dorsal vascular flap over the neourethra by Snodgrass technique reduces the rate of the fistula formation.
