Abstract
Insomnia, a widespread public health issue, is associated with substantial distress and daytime functionality impairments and can predispose to depression and cardiovascular disease. Cognitive Behavioral Anti-insomnia therapies including benzodiazepines often face limitations due to patient adherence or potential adverse effects. This study focused on identifying novel bioactive compounds from medicinal plants, aiming to discover and develop new therapeutic agents with low risk-to-benefit ratios using computational drug discovery methods. Through a systematic framework involving compound library preparation, evaluation of drug-likeness and pharmacokinetics, toxicity prediction, molecular docking, and molecular dynamic simulations, two natural compounds such as 2-(4-hydroxy-3-methoxyphenyl)-8-methoxy-6-prop-2-enyl-3,4-dihydro-2H-chromen-3-ol from Ocimum tenuiflorum and 7-(2-hydroxypropan-2-yl)-1,4a-dimethyl-9-oxo-3,4,10,10a-tetrahydro-2H-phenanthrene-1-carboxylic acid from Poria cocos exhibited high binding affinity with orexin receptor type 1 (OX1R) and type 2 (OX2R), surpassing commercial drugs used in insomnia treatment. Additionally, they showed interactions with critical amino acid residues within the receptors that play crucial roles in competitive inhibitor activity, like commercial drugs such as Suvorexant, Lemborexant, and Daridorexant. Further, molecular dynamics simulations of the protein-ligand complexes under conditions that mimic the in vivo environment revealed both compounds' sustained and robust interactions with the OX1R and OX2R, reinforcing their potential as effective therapeutic candidates. Furthermore, upon evaluating both compounds' drug-likeness, pharmacokinetics, and toxicity profiles, it was discerned that they displayed considerable drug-like properties and favorable pharmacokinetics, along with diminished toxicity. The research provides a solid foundation for further exploring and validating these compounds as potential anti-insomnia therapeutics.

Abstract
Guillain-Barre Syndrome (GBS) is considered as an immune mediated inflammatory disease of peripheral nerves and nerve roots. The significance of CSF total protein (CSF-TP) in subtypes of Guillain-Barre syndrome has not been well established. This observational, cross sectional study's aim was to identify association of CSF total protein with clinical heterogeneity, disease severity and electrophysiological subtypes in GBS patients. This study was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from September 2017 to February 2019 on 50 (fifty) admitted GBS patients as per inclusion and exclusion criteria. About 3-5 ml of CSF was taken around 10±2 days from disease onset for detection CSF cell count and protein. Pattern of clinical presentation, disability status by Hughes scale and NCS findings of these patients was documented. Mean CSF-TP were substantially higher for Sensori-motor GBS (195.42 mg/dl) and GBS with cranial involvement (226.12 mg/dl) than that of GBS with motor (134.00 mg/dl) and autonomic involvement (155.21 mg/dl). Mean CSF total protein (CSF-MTP) in severely ill GBS patients (Grade-IV) was 217.04 mg/dl and very severely ill GBS patients (Grade-V) was 138.00mg/dl which was significantly higher than mean CSF total protein in mild GBS patients (CSF-MTP: 99.86mg/dl) and moderately ill GBS patients (CSF-MTP: 172.00 mg/dl). Mean CSF total protein is 245.00mg/dl in AIDP which is also higher than mean CSF total protein of AMAN (153.36 mg/dl) and AMSAN (165.17mg/dl). CSF-TP is thought to be a sensitive test for GBS in the second week after onset, but it may be a reliable predictor of clinical severity. There is a significant association of CSF-TP elevation with demyelinating electrophysiologic pattern.

Abstract
Stroke is the second-leading cause of death and also a leading cause of combined death and disability. In Bangladesh, stroke prevalence is 11.39 per 1000 population, but highest prevalence of stroke is 14.71 per 1000 population in the Mymensingh division. Hyperuricemia has been reported as an independent risk factor for stroke in different studies and a significant association between serum uric acid and dyslipidemia has also been stated. On the contrary, some studies suggest that uric acid has a neuroprotective role. This cross-sectional study was completed in the Medicine Department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2021 to January 2023. In this cross-sectional study, 352 adult acute ischemic stroke patients were included from the Medicine Department of Mymensingh Medical College Hospital. Serum uric acid and fasting serum lipid levels were measured within 48 hours of admission. The mean age ±SD of the respondents was 61.9±12.8 years. Hyperuricemia was found among 18.2% of respondents, whose mean ±SD serum uric acid was 5.7±1.9 mg/dl. Dyslipidemia was present in 88.4% of patients. The mean ±SD of the National Institutes of Health Stroke Scale (NIHSS) score was 12.0±5.9. Most of the patients (65.6%) were suffering from moderate stroke, followed by moderate to severe stroke (15.1%), severe stroke (10.8%) and minor stroke (8.5%). After multiple linear regressions, the independent variables age, gender, serum uric acid and total cholesterol were found to be significant predictors of the NIHSS score of the respondents. In conclusion, the majority of acute ischemic stroke patients have an association with dyslipidemia, but only around one-fifth of patients have hyperuricemia. There is a significant association of high serum uric acid and high serum total cholesterol with stroke severity (NIHSS score). But low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and, triglycerides have no association with stroke severity.

Abstract
Antioxidants, which have long been deemed an indispensable guardian of human health, play a pivotal role in bolstering the body's defense against a plethora of diseases. Three well-recognized seaweeds in Bangladesh, including Caulerpa racemosa, Padina tetrastromatica, and Hypnea musciformis, were subjected to meticulous analysis to reveal their phytochemical composition, antioxidant activity, and antimicrobial efficacy using advanced spectroscopic and disc diffusion methods. Intriguingly, we observed that C. racemosa emerges as frontrunners, possessing a substantial arsenal of phenol (143.08 ± 18.51 mg gallic acid equivalent g─1) and flavonoid (63.79 ± 2.16 mg rutin equivalent g─1). More fundamentally, C. racemosa exhibits a notable enrichment in the content of tannin (73.58 mg RE g─1) and chlorophyll (13.50 mg g─1), as well as, antioxidant capacity (4457.67 μg g─1). P. tetrastromatica, on the other hand, displayed commendable effectiveness in scavenging the DPPH radical, with percentages ranging from 53.98 to 62.17%. In terms of hydroxyl radical (OH•) scavenging activity, C. racemosa exhibited the highest efficacy at 400 g mL─1. Fascinatingly, C. racemosa exhibited an impressive antioxidant potential, as evidenced by its exceptionally low IC50 value of 5.58 μg mL-1 for OH• scavenging, whereas P. tetrastromatica showed impressively low value of 0.96 μg mL-1 for DPPH scavenging. Although the three seaweeds demonstrated limited efficacy against a spectrum of five human pathogenic bacteria, their potential as abundant sources of antioxidants remains unscathed. Notably, heatmap and PCA analysis revealed that C. racemosa and P. tetrastromatica emerge as the leading contender for studied antioxidant compounds, demonstrating their proclivity for antioxidant extraction, a trait that could be exploited for large-scale production of these valuable compounds.

Abstract
Kratom (Mitragyna speciosa Korth. Havil) has been considered a narcotic drug for years, barred by the law in many parts of the world, while extensive research over the past few decades proves its several beneficial effects, some of which are still in ambiguity. In many countries, including Thailand, the indiscriminate use and abuse of kratom have led to the loss of life. Nonetheless, researchers have isolated almost fifty pure compounds from kratom, most of which are alkaloids. The most prevalent compounds, mitragynine and 7-hydroxy mitragynine, are reported to display agonist morphine-like effects on human μ-opioid receptors and antagonists at κ- and δ-opioid receptors with multimodal effects at other central receptors. Mitragynine is also credited to be one of the modulatory molecules for the Keap1-Nrf2 pathway and SOD, CAT, GST, and associated genes' upregulatory cascades, leading it to play a pivotal role in neuroprotective actions while evidently causing neuronal disorders at high doses. Additionally, its anti-inflammatory, antioxidative, antibacterial, and gastroprotective effects are well-cited. In this context, this review focuses on the research gap to resolve ambiguities about the neuronal effects of kratom and demonstrate its prospects as a therapeutic target for neurological disorders associated with other pharmacological effects.

Abstract
Vitamin D is important for health and disease. Milk is a good natural source of it, and calcium-vitamin D supplements are widely available over-the-counter and prescribed in clinical practice. But the effect of milk intake and calcium-vitamin D supplementation on serum vitamin D status is not known. This cross-sectional study was done to see the relationship between vitamin D status and milk intake or oral calcium-vitamin D supplementation using a structured questionnaire and carried out in a private consultation centre of Dhaka city, the capital of Bangladesh from July 2017 to March 2018. Serum 25-hydroxyvitamin D [25(OH)D] level was measured by radioimmunoassay. Out of 259 patients, 64.1% had vitamin D deficiency defined as serum 25(OH)D level <20ng/mL. Sixty one percent of those who had serum 25(OH)D level <20ng/mL did not take milk or milk products, while 53.0% of those having 25(OH)D level ≥20ng/mL did not take milk. Approximately 89.0% of those who had serum 25(OH)D level <20ng/mL did not take oral calcium-vitamin D, whereas 72.0% of those having 25(OH)D level ≥20ng/mL did not take oral calcium-vitamin D (p=0.001). In the multiple logistic regression analysis, there were significantly increased odds of vitamin D deficiency for females as compared to males [odds ratio (OR) 2.48, 95% confidence interval (CI) 1.34-4.56] and not taking oral vitamin D as compared to taking oral vitamin D (OR 3.56, 95% CI 1.74-7.28). Vitamin D deficiency is widely prevalent. Lack of milk intake and calcium-vitamin D supplementation are more commonly associated with serum vitamin D deficiency, and calcium-vitamin D supplementation is specially important in females.

Abstract
Upper back pain is as painful or troublesome as the pain in the lower back or the neck. Myofascial pain syndrome which is most common cause of upper back pain is characterized by localized musculoskeletal pain and tenderness in association with trigger points. The aim of the study was to correlate the improvement of myofascial pain syndrome patients with proper and timely physical therapy. This quasi experimental study was conducted in the department of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh, from 1st January 2008 to 31st August 2008 to see the role of rehabilitation exercise on myofascial pain syndrome causing upper back pain. Sixty (60) patients of myofascial pain syndrome causing upper back pain were randomly assigned for treatment; out of which 23(38.33%) were male and 37(61.66%) were female. The male and female ratio was 1:1.6. The patients selected for the trial were divided into two groups: Group A and Group B. In group A (n=28) the patients were treated with thermotherapy- Microwave diathermy, non-steroidal anti inflammatory drugs and activities of daily living instructions and in Group B (n=32) with same interventions in addition to rehabilitation exercises. Treatment duration was 6 weeks. The difference of treatment improvement was statistically significant (p<0.05) from 1st week up to 6th week. After complete course of treatment 67.86% patients in Group A and 78.13% patients in group B reported improvement. So rehabilitation exercises can be a valuable adjunct to other modalities of treatment of myofascial pain syndrome causing upper back pain.

Abstract
Approximately 10.0% of tuberculosis (TB) Infected individuals develop clinical disease in the absence of immune suppression suggests that individual factors may play a role in the response to infection. Body's immune function is boosted by micronutrient and also plays a major role in response to tubercular infection. Someone, may argue that cell mediated immunity is compromised in iron deficiency before anemia becomes apparent. This descriptive observational study intended to assess serum iron profile in patients suffering from pulmonary tuberculosis. This study included 56 newly diagnosed sputum smear positive and negative pulmonary tuberculosis patients as per inclusion and exclusion criteria and was conducted at the department of the Internal Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh with the collaboration of the Biochemistry department, BSMMU, Bangladesh from February 2017 to January 2018. Collected data were recorded in a structured questionnaire and compiled and appropriate analyses were done by using computer-based software Statistical Package for Social Sciences (SPSS) version 23.0. Out of 56 patients, majority was young and at reproductive age, male was predominant (78.6%) with a male to female ratio of 3.7:1. More than three fourth 43(81.0%) patients were found to have low serum iron concentration. Majority 45(80.4%) patients had normal serum TIBC, 6(10.7%) had low serum total iron binding capacity (TIBC) and 5(8.9%) had high serum TIBC. Almost two third 36(64.3%) patients had low serum transferrin saturation and 20(35.7%) had normal serum transferrin saturation. Majority 31(55.4%) patients had normal serum ferritin, 2(3.6%) had low serum ferritin and 23(41.1%) had high serum ferritin. Serum iron concentration and serum ferritin were significantly associated with chest x-ray abnormalities (p<0.01). Half of the patients were smear positive for acid fast bacilli (AFB) (50.0%). No significant association was found between sputum positive for AFB with iron profile status. In smear positive pulmonary tuberculosis patients, more than three fourth (78.6%) patients had low serum iron concentration at baseline and majority 20(80.0%) patients had normal serum iron concentration after 2(two) months. Mean serum iron concentration was 41.8±17.6mcg/l in baseline and 70.4±29.7mcg/l in at 2(two) month. More than sixty percent (60.7%) patients had low serum transferrin saturation at baseline and 20(80.0%) patients had normal serum transferrin saturation after 2(two) months. Mean serum transferrin saturation was 18.1±7.6% at baseline and 31.2±19.4% in at 2(two) months. After 2(two) months follow up serum iron concentration and serum transferrin saturation had significant improvement (p<0.05). Significant iron deficiency status occurred in pulpmonary tuberculosis and which improved after anti-tubercular treatment without iron supplementation.

Abstract
Coronary artery disease (CAD) is one of the important causes of mortality worldwide. South Asians, notably Indians are unduly prone to develop CAD with its incidence being doubled in the last three decades among both rural and urban settlers. CAD prevalence of in Bangladesh is not known. There are merely a limited number of small-scale epidemiological studies are existing. Recent data indicates CAD prevalence in our country to lie between 1.85-3.4% in rural and 19.6% in an urban sample of working professionals. Despite marked disparity in values, the disease seems to be in rising trend. Patients with concomitant CAD and carotid artery disease are at increased risk of developing peri-operative neurological events including stroke. By far, the prevalence of carotid artery disease in candidates of CABG has not yet been determined in our country. There is a lack of pre-operative guidelines as well for the necessary vascular investigations that should be performed on CABG candidates before they go to the operation table. Pre-operative non-invasive carotid Doppler ultrasonography is a useful screening tool for carotid artery disease in all patients undergoing CABG. This was a cross-sectional observational study, was conducted in the Radiology & Imaging department of Ibrahim Cardiac Hospital & Research Institute, Dhaka, Bangladesh from January 2017 to June 2017. The present cross-sectional study was intended to determine the prevalence of concurrent occurrence of carotid and coronary artery disease in elderly patients undergoing CABG. Total 210 elderly (from 60 & above) patients scheduled for CABG taken as study population. There was bilateral carotid atherosclerotic plaque in 15(12.2%) patients. Right carotid plaque was in 69(56.0%) patients, left carotid plaque in 54(43.9%) patients. Carotid stenosis grading was done in percentage (%). There was significant (>50.0%) stenosis of right carotid system in 12 patients (17.4%) and significant stenosis of left carotid system in 18 patients (33.3%). Right carotid system & bulb was the most common site of plaque formation. We can conclude from this study that a substantial proportion of patients after a particular age possess carotid artery disease simultaneously with coronary artery disease, routine evaluation of carotid arteries of the elderly patients scheduled for CABG is strongly suggested.

Abstract
Cerebrovascular disease is the third most familiar cause of mortality worldwide and in Bangladesh. The reported prevalence of stroke in Bangladesh is 0.3%. Age, high serum glucose, elevated admission blood pressure, fever, large infarction size, and hyperhomocysteinemia has been reported to be risk factor for early post-stroke neurological deterioration. Early serum homocysteine level estimation can predict the early prognosis of ischemic stroke. In a developing country like Bangladesh, an earlier stroke outcome prediction for guiding therapeutic approach is essential. This study aimed to specify the role of estimating serum homocysteine during the early phase of acute ischemic stroke to assume an early prognosis that would guide- a management plan, the need to stay in the hospital and the need for intervention. This cross-sectional descriptive study was performed at the Department of Medicine, Mymensingh Medical College Hospital, Bangladesh from October 2021 to April 2022. Radiologically confirmed all ischemic stroke patients admitted at the Department of Medicine, Mymensingh Medical College Hospital, during the study period fulfilling the inclusion and exclusion criteria were included in this study. Non-probability purposive sampling technique was used. Data was collected using a pre-designed case record form. Quantitative data were represented as mean and standard deviation and qualitative data as frequency and percentage. The comparison was made by Chi-square test and independent samples t-test using SPSS (version 26.0). During the study period, among 716 stroke patients, 59 ischemic stroke patients were included in this study. The mean age of the patients was 64.0±11.72 years. After 72 hours of supportive treatment, early neurological outcomes were observed using NIHSS scoring. Out of 59 patients, the condition of 45(76.0%) patients improved or remained stable (END-) and the state of 14(24.0%) patients worsened (END+). Elderly age-raised temperature and elevated blood glucose level are known to increase infarction size, but only elevated temperature (p value 0.009) has statistical significance in this study. The mean homocysteine level ±SD was 20.22±6.95μmol/L, which is above the normal (<15μmol/L). The level was above average for both outcome groups. Serum homocysteine level was significantly higher in END(+) group (31.59±2.98μmol/L) than END(-) group (16.69±2.66μmol/L) and p value was <0.001.

Abstract
Two-photon polymerization lithography is promising for producing three-dimensional structures with user-defined micro- and nanoscale features. Additionally, shrinkage by thermolysis can readily shorten the lattice constant of three-dimensional photonic crystals and enhance their resolution and mechanical properties; however, this technique suffers from non-uniform shrinkage owing to substrate pinning during heating. Here, we develop a simple method using poly(vinyl alcohol)-assisted uniform shrinking of three-dimensional printed structures. Microscopic three-dimensional printed objects are picked and placed onto a receiving substrate, followed by heating to induce shrinkage. We show the successful uniform heat-shrinking of three-dimensional prints with various shapes and sizes, without sacrificial support structures, and observe that the surface properties of the receiving substrate are important factors for uniform shrinking. Moreover, we print a three-dimensional mascot model that is then uniformly shrunk, producing vivid colors from colorless woodpile photonic crystals. The proposed method has significant potential for application in mechanics, optics, and photonics.

Abstract
This research investigated the antihypertensive effects of tamarind products and compared their potentials based on an animal model's data verified by molecular docking, multitarget interactions, and dynamic simulation assays. GC-MS-characterized tamarind products were administered to cholesterol-induced hypertensive albino rat models. The two-week-intervened animals were dissected to collect their serum and organs and respectively subjected to analyses of their hypertension-linked markers and tissue architectures. The lead biometabolites of tamarinds interacted with eight target receptors in the molecular docking and dynamic simulation studies and with multitarget in the network pharmacological analyses. The results show that the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), C-reactive protein (CRP), troponin I, and lipid profiles were maximally reinstated by the phenolic-enriched ripened sour tamarind extract compared to the sweet one, but the seed extracts had a smaller influence. Among the tamarind's biometabolites, ϒ-sitosterol was found to be the best ligand to interact with the guanylate cyclase receptor, displaying the best drug-likeliness with the highest binding energy, -9.3 Kcal. A multitargeted interaction-based degree algorithm and a phylogenetic tree of pathways showed that the NR3C1, REN, PPARG, and CYP11B1 hub genes were consistently modulated by ϒ-sitosterol to reduce hypertension and related risk factors. The dynamic simulation study showed that the P-RMSD values of ϒ-sitosterol-guanylate cyclase were stable between 75.00 and 100.00 ns at the binding pocket. The findings demonstrate that ripened sour tamarind extract may be a prospective antihypertensive nutraceutical or supplement target affirmed through advanced preclinical and clinical studies.

Abstract
Over the past few decades, complementary and alternative treatments have become increasingly popular worldwide. The purported therapeutic characteristics of natural products have come under increased scrutiny both in vitro and in vivo as part of efforts to legitimize their usage. One such product is tea tree oil (TTO), a volatile essential oil primarily obtained from the native Australian plant, Melaleuca alternifolia, which has diverse traditional and industrial applications such as topical preparations for the treatment of skin infections. Its anti-inflammatory-linked immunomodulatory actions have also been reported. This systematic review focuses on the anti-inflammatory effects of TTO and its main components that have shown strong immunomodulatory potential. An extensive literature search was performed electronically for data curation on worldwide accepted scientific databases, such as Web of Science, Google Scholar, PubMed, ScienceDirect, Scopus, and esteemed publishers such as Elsevier, Springer, Frontiers, and Taylor & Francis. Considering that the majority of pharmacological studies were conducted on crude oils only, the extracted data were critically analyzed to gain further insight into the prospects of TTO being used as a neuroprotective agent by drug formulation or dietary supplement. In addition, the active constituents contributing to the activity of TTO have not been well justified, and the core mechanisms need to be unveiled especially for anti-inflammatory and immunomodulatory effects leading to neuroprotection. Therefore, this review attempts to correlate the anti-inflammatory and immunomodulatory activity of TTO with its neuroprotective mechanisms.

Abstract
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.

Abstract
Haematohidrosisis manifested by sweating mixed with blood. It is a rare disease and there are scarce literature regarding case report. We are describing five cases of haematohidrosis in different age group here in this case series. In case 1- a 20 year old woman was admitted with history of recurrent haemorrhage from various sites without any trauma or anticoagulant or antipletlet medication. There was no evidence of local trauma. Physical examination was unremarkable. Her blood workup came out insignificant. In case 2- a 10 year old boy was admitted with epistaxis, conjunctival bleeding, haematuria and per rectal bleeding without any history of injury. He had no history of medicine which would cause bleeding. Physical examination and laboratory profile were insignificant. In case 3- a 15 year old boy presented with recurrent haematuria and conjunctival haemorrhage without any trauma. No history of medication that would cause the bleeding. His systemic examination and laboratory profile was unremarkable. In case 4- a 25 year old woman presented with bleeding from ear, nose and eyes without any local trauma. She was not on any medication that would cause bleeding. Her systemic inquiry and laboratory profile was unremarkable. In case 5- a 20 year old woman presented with bleeding from eyes, ears and umbilicus. There was no evidence of self-inflicted injury. She had features of anxiety disorder. Other systemic examination and laboratory profile was unremarkable. All the cases were labelled as haematohidrosis and treated with propranolol with successful outcome. We report this case series to build up awareness and disseminate clinical knowledge.

Abstract
Thyroidectomy is one of the commonest operative procedures performed in the neck and injury to recurrent laryngeal nerve (RLN) is not uncommon. It results in hoarseness to serious respiratory distress depending on the extent of the injury. The incidence of RLN injury varies widely and is multifactorial depending on the extent of surgical procedures, experience and expertise of the surgeons, nature of the thyroid diseases and a wide range of anatomical variations. Peroperative routine identification of the nerve during thyroidectomy can be a way to prevent injury. Despite recommendation for identification of the RLN peroperatively in thyroid surgery, a debate still exists whether the nerve to be identified peroperatively or not, to avoid its inadvertent injury. The aim of this study was to compare the incidence of RLN injury between two groups where RLN was identified peroperatively in one group and the nerve was not attempted for identification in the other group in thyroid surgery. A comparative cross-sectional study was carried out in the department of surgery and otolaryngology at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from June 2018 to November 2019, on patients who underwent elective thyroid surgery. Patients were included in RLN identified group and in RLN not identified group, by individual surgeons' preference to identify or not to identify the RLN peroperatively. Peroperative identification of the nerve was done by direct visualization. All cases were evaluated for vocal cord palsy preoperatively, during extubation and postoperatively. Patient's particulars, other parameters and perioperative data were recorded. A total of 80 cases were included in this study, 40 cases (50.0%) in the peroperative RLN identified group and 40 cases (50.0%) in the RLN not identified group. Unilateral RLN palsy was encountered in 2.5% (2 cases) in the RLN identified group and 6.3% (5 cases) in the nerve not identified group (p value 0.192). Transient unilateral RLN palsy was seen in 7.5% (6 cases) of patients; 2.5% (2 cases) in the RLN identified group and 5.0% (4 cases) in the RLN not identified group. And 1.3% (1 case) of permanent unilateral RLN palsy was encountered in this study, which was in the RLN not identified group; there was no permanent palsy in the RLN identified group. We did not encounter any bilateral RLN palsy. There was no statistically significant difference in the incidence of RLN injury between the peroperatively RLN identified group and no attempt to identify the nerve group despite recommendation for peroperative RLN identification in thyroid surgery to avoid its inadvertent injury. However, from this study, we recommend peroperative RLN identification in thyroid surgery to enhance surgical skill.

Abstract
Wilson disease (WD) is an autosomal recessive disorder of copper metabolism with diverse clinical manifestations. Zinc (Zn) has been used for treatment of WD. Recent studies showed low serum zinc level in patients suffering from WD than the normal. This cross-sectional analytical study has been designed to compare the serum zinc level between paediatric patients suffering from WD but yet not started treatment and children who have normal ALT level. This study was carried out at the Department of Pediatric Gastroenterology and Nutrition, BSMMU, Dhaka, Bangladesh from July 2018 to June 2019. Total 51 children were included in this study. Among them 27 were diagnosed case of WD aged between three to eighteen years and 24 children of same ages who were suffering from other than liver disease having normal ALT were included as volunteers. The patients of WD were divided into four groups according to their presentation as acute hepatitis, chronic liver disease (CLD), acute liver failure & neuropsychiatric manifestation. Informed written consent was obtained from all patients and volunteers for participation in this study. Along with other physical findings and laboratory investigations 3 ml of venous blood were collected for estimation of serum zinc level. After estimation of serum zinc level results were analyzed statistically. The difference in serum zinc levels were compared between the groups. Serum zinc level was significantly lower in Wilson disease patients (43.8±19.7μg/dl; range: 13-83) compared to volunteers group (67.8±11.8μg/dl; range: 47-97) p<0.001. Among the diseased group, serum zinc level were significantly lower in 18 CLD (38.4±17.4μg/dl) and in 4 acute liver failure (33.1±3.7μg/dl) compared to 4 acute hepatitis (71.8±4.3μg/dl) (p=0.001) and (p<0.001) respectively. Mean serum zinc level was low in 4 Wilsonian acute liver failure (33.1±3.7μg/dl), which was significant compared to those (23) who presented as Wilson disease non acute liver failure (45.7±20.8μg/dl) (p=0.013). Serum zinc level was significantly lower in Wilson disease children compared to the volunteers. Zinc level was also found significantly low in Wilson disease presented as CLD and acute liver failure in comparison to Wilson disease presented as acute hepatitis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diarrhea is one of the leading causes of preventable death in developing countries, mainly caused by bacterial infections and traditional therapies are very common in diarrheal incidences. Meda Pata (Litsea glutionsa) has a long history of use as traditional medicine for diarrhea, dysentery, and spasm in Bangladesh, India, and some other Asian countries. AIM OF THE STUDY This research reports the antidiarrheal effects of Meda Pata (Litsea glutinosa leaf extract, LGLEx) in animal models. The work has been supported by in silico molecular docking study to verify the effects. MATERIALS AND METHODS The antidiarrheal effect of LGLEx was investigated in castor oil-induced diarrhea, magnesium sulfate-induced diarrhea, and gastrointestinal motility test models. Antidiarrheal effects were supported by a molecular docking study through an interaction between LGLEx's GC-MS analyzed imidazole-containing compounds and muscarinic acetylcholine receptor (PDB: 4U14) and 5-HT3 receptor (PDB: 5AIN). RESULTS LGLEx potentially reduced the diarrheal incidences in in vivo assays reducing gastrointestinal motility. The maximum diarrheal inhibition was obtained in the castor oil-induced model (62.63%) and and BaSO4-induced model (73.14%), which were statistically significant (P < 0.05) when compared to the reference drug loperamide. In the castor-oil and BaSO4-induced models, peristaltic movement was reduced by 25.96% and 32.17%, respectively. Biochemical markers particularly IgE, C-reactive proteins, and serum electrolytes were significantly (P < 0.0) restored in treated groups. A Molecular docking analysis revealed that two compounds (1-Ethyl-2-hydroxymethylimidazole and 1,6-Anhydro-beta-D-glucofuranose demonstrated the highest binding affinity with target receptors muscarinic acetylcholine receptor (PDB: 4U14) and 5-HT3 receptor (PDB: 5AIN) confirming their drug likeliness. The findings indicate a high potential antidiarrheal impact that warrants further investigation for its therapeutic application.

Abstract
Plant-based nanoformulation is one of the novel approaches for therapeutic benefits. This research synthesized a silver nanoparticle from the polyherbal combination of four plants/seeds (Momordica charantia, Trigonella foenum-graecum, Nigella sativa, and Ocimum sanctum) and investigated its antidiabetic effects in streptozotocin-induced Wistar albino rat model. The polyherbal extract (PH) was extracted by the Soxhlet-solvent extraction method and the resulting crude extract was undergone for silver nanoparticle synthesis. The PH extract was subjected to a four-week intervention in fructose-fed streptozotocin-induced Wistar Albino rats' models and in vitro antioxidative tests. Experimental animals (age: 6-7 weeks, male, body weight: 200-220 g), were divided into five groups including normal control (NC), reference control (RC), diabetic control (DC), and treatment groups PH200, PH100, and PHAgNP20. After three weeks of intervention, body weight, weekly blood glucose level, oral glucose tolerance test, AST, ALT, alkaline phosphatase, total cholesterol, triglycerides, uric acid, urea, and creatinine level of PH200 were found to be significantly (P < 0.05) improved compared to the diabetic control. The same dose demonstrated better regeneration of damaged pancreatic and kidney tissues. In vitro antioxidant assay manifested promising IC50 values of 86.17 μg/mL for DPPH, 711.04 μg/mL for superoxide free radical, and 0.48 mg/mL for Iron chelating activity of the polyherbal extract. GC-MS analysis impacted the major volatile compounds of the PH. The data demonstrate that the PH and its nanoparticles could be a novel source of antidiabetic therapeutics through an advanced dose-response study in the type 2 diabetic model.

Abstract
CHADS₂ and CHA₂DS₂-VASc scores are widely used in clinical practice and include similar risk factors for the development of coronary artery disease (CAD). It is known that the factors comprising the newly defined CHA₂DS₂-VASC-HSF score promote atherosclerosis and associated with severity of CAD. Objective of the study was to find out the association of the CHA₂DS₂-VASC-HSF score with the severity of CAD in patients with ST elevation myocardial infarction (STEMI). One hundred (100) patients with STEMI were enrolled in this study after considering inclusion and exclusion criteria over a one year period from October, 2017 to September, 2018 in the Department of Cardiology, National Institute of Cardiovascular Diseases, Dhaka, Bangladesh. Coronary angiogram was done within index hospitalization and coronary artery disease severity was assessed by SYNTAX score system. Patients were divided into two groups on the basis of SYNTAX score. Patients with SYNTAX score ≥23 assigned as Group I and SYNTAX score <23 assigned as Group II. The CHA₂DS₂-VASC-HSF score was calculated. Cut-off value of high CHA₂DS₂-VASC-HSF score was ≥4.0. In this study mean age of study population was 51.8±9.8, male patients were predominant (79.0%). Among the studied patients, highest percentage had history of smoking followed by hypertension, diabetes mellitus and family history of CAD in Group I patients. It was found that DM and family history of CAD and history of stroke/TIA were significantly higher in Group I than Group II. An increasing trend of SYNTAX score was observed according to the CHA₂DS₂-VASc-HSF score. SYNTAX score was significantly higher in CHA2DS2-VASc-HSF score ≥4 than CHA₂DS₂-VASc-HSF score <4 (26.3±6.3 vs. 12.1±7.7, p<0.001). Patients with CHA₂DS₂-VASC-HSF score ≥4 had severe coronary artery disease than CHA₂DS₂-VASC-HSF score <4 assessed by SYNTAX score with 84.4% sensitivity and 81.9% specificity (AUC:0.83, 95% CI: 0.746-0.915, p<0.001). CHA₂DS₂-VASc-HSF score was positively correlated with the severity of CAD. This score could be considered as a predictor of coronary artery disease severity.

Abstract
The conventional technique of harvesting free non-vascularized fibular grafting is associated with different scale of morbidity and usually a long scar. We follow a technique that causes minimum interference to the surrounding soft tissues to harvest the desired length of fibula. This prospective study was performed at Department of Orthopaedics, Dhaka Medical College Hospital from January 2018 to December 2018. Thirty patients of average age 10.5 years (range 8 to 14 years) were taken up for the study. The fibula was harvested by two separate incisions, 1 cm each at proximal and distal extent of proposed length of graft after elevating the periosteum circumferentially using a periosteum elevator. Compression bandage and above knee plaster immobilization was applied that help to reduce hematoma formation. The mean follow up is 12 months. The patients were evaluated clinically and by radiology. Twenty nine patients showed good results. One patient had delayed wound healing resulting in fair result. This modified approach of harvesting fibula reduces donor site morbidity and is safer and easier than conventional approach.

Abstract
Stroke, usually a focal rather than global neurological deficit resulting from vascular origin with sudden onset, may be with cerebral infarction or intracerebral haemorrhage. It results in brain oedema following vascular injury and electrolyte imbalance. A descriptive cross sectional study was carried out in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh during March 2016 to May 2018 to assess the electrolyte levels among 220 purposively selected patients with stroke confirmed by CT scan. Data were collected by the principal investigator himself by using interview schedule and case record form after attaining consent. Blood samples were collected from the patients to carry out biochemical and haematological tests and to assess serum electrolyte levels. Data were cross-checked for completeness, consistency and relevancy, and were analyzed by computer software SPSS 20.0. Age was significantly higher in haemorrhagic stroke (64.88±13.00 years) than ischaemic stroke (60.92±13.96 years). Male (55.91%) were predominant than female (44.09%). One hundred nineteen (54.09%) patients had ischaemic stroke and 101(45.91%) patients had haemorrhagic stroke. The serum concentration of Na+, K+, Cl- and HCO₃- were measured during acute period of stroke. Imbalance in serum Sodium, Chloride, Potassium and Bicarbonate level were observed in 37.27%, 29.55%, 23.18% and 6.36% patients respectively. Hyponatremia, hypokalemia, hypochloremia and acidosis were most common electrolyte imbalance in both ischaemic and haemorrhagic strokes. In ischaemic stroke hyponatremia was 35.29%, hypernatremia was 3.36%, hypokalemia 19.33%, hyperkalemia 0.84%, hypochloraemia 30.25%, hyperchloraemia 3.36%, acidosis was in 6.72% and alkalosdis in 1.68% patients while in haemorrhagic stroke hyponatremia 33.66%, hypernatremia 1.98%, hypokalaemia 22.77% hyperkalemia 3.96%, hypochloremia 19.80%, hyperchloraemia 4.95%, acidosis 2.97% and alkalosis was in 0.99% of patients. Mortality was more in hyponatremic, hypokalemic and in hypochloremic patients.

Abstract
The study was intended to evaluate efficacy of Intra-arterial nitroglycerin through the sheath at the end of a transradial procedure to preserve the patency of the radial artery. This prospective observational study was done in the Department of Cardiology, National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh from May 2017 to April 2018, by including a total 200 patients undergoing coronary procedures (CAG and / or PCI) through TRA. RAO was defined as an absence of antegrade flow or monophasic flow or invert flow on Doppler study. In this study 102 patients (Group I) received 200 mcg intra-arterial nitroglycerine, prior to trans-radial sheath removal. Another 98 patients (Group II) did not receive intra-arterial nitroglycerine prior to trans-radial sheath removal. Conventional haemostatic compression methods were applied (average 2 hours) in both groups of patients. Evaluation of radial arterial arterial blood flow by colour Doppler study was done on next day after the procedure in both groups. Results of this study in which RAO was determined by vascular doppler study showed that frequency of radial artery occlusion were 13.5% one day after transradial coronary procedures. We found the incidence was 8.8% vs. 18.4%, (p=0.04) in Group I and Group II respectively. The incidence of RAO was significantly lower in post procedural nitroglycerine group. From multivariate logistic regression analysis diabetes mellitus (p = 0.02), hemostatic compression time for more than 02 hours after sheath removal (p = <0.001) and procedure time (p = 0.02) was predictors of RAO. So, the administration of nitroglycerin at the end of a transradial catheterization reduced the incidence of RAO, as shown by 1 day after the radial procedure by doppler ultrasound.

Abstract
This study constructed the phytochemical profiles of Adenostemma lavenia (L) methanol extract (MEAL) and investigated its anti-nociceptive, anti-diarrheal, antipyretic, thrombolytic and anthelmintic effects. The GC-MS characterized MEAL had undergone an in vivo antipyretic effect assayed on Swiss albino mice adopting the yeast-induced pyrexia model, antinociceptive activity tested following acetic acid-induced writhing and formalin-induced licking paw models, anti-diarrheal effect in castor oil-induced diarrhea, castor oil-induced enteropooling, and charcoal-induced intestinal transit tests, in vitro thrombolytic effect using clot-lysis model and anthelmintic effects assayed on Tubifex tubifex nematode. The MEAL biometabolites and associated proteins of target diseases were interacted with computational analysis. The MEAL showed a significant dose-dependent percentage of inhibition in acetic acid-induced writhing and formalin-induced paw licking displaying inhibition of 80.40% in acetic acid-induced writhing and 36.23% and 58.21% in the second phase of the formalin-induced model. The MEAL inhibition of 34.37%, 35.29%, and 42.95% in castor oil-induced diarrhea, castor oil-induced enteropooling, and charcoal-induced gastrointestinal motility, respectively. The MEAL significantly reduced yeast-induced pyrexia. Its biometabolites showed remarkable (-4.1 kcal/mol to 7.4 kcal/mol) binding affinity with the protein receptors. Caryophyllene and Cyclobarbital yielded the best binding scores in this research. Results suggest that pure compounds-based pharmacological investigations are necessary to affirm the therapeutic effects.

Abstract
Porphyria cutanea tarda is a rare disorder of heme metabolism due to deficiency of the enzyme uroporphyrinogen decarboxylase which is manifested as some typical dermatological features and hepatic dysfunction. The Hepatitis-C virus co-infection is common and it can be aggravated by other environmental factors. We report a case of porphyria cutanea tarda in a 37-year-old woman, who presented with recurrent skin blisters and has concomitant Hepatitis-C virus infection. She was taking oestrogen containing oral contraceptive pill for a long duration. The diagnosis of porphyria cutanea tarda was considered on the basis of clinical features and high level of urine porphyrin level. She was put on hydroxychloroquine and combination drugs for Hepatitis-C virus with significant improvement after 3 months of therapy.

Abstract
We report simultaneously acquired local and nonlocal transport spectroscopy in a phase-biased planar Josephson junction based on an epitaxial InAs-Al hybrid two-dimensional heterostructure. Quantum point contacts at the junction ends allow measurement of the 2×2 matrix of local and nonlocal tunneling conductances as a function of magnetic field along the junction, phase difference across the junction, and carrier density. A closing and reopening of a gap was observed in both the local and nonlocal tunneling spectra as a function of magnetic field. For particular tunings of junction density, gap reopenings were accompanied by zero-bias conductance peaks (ZBCPs) in local conductances. End-to-end correlation of gap reopening was strong, while correlation of local ZBCPs was weak. A model of the device, with disorder treated phenomenologically, shows comparable conductance matrix behavior associated with a topological phase transition. Phase dependence helps distinguish possible origins of the ZBCPs.

Abstract
The phytochemicals of Tamarindus indica seed hydroalcoholic extract were exploited as a biocatalyst for the sustainable synthesis of magnesium oxide nanoparticles (MgO-NPs). This research investigated the cardioprotective effects of biosynthesized magnesium oxide nanoparticle (MgO-NPs). The biosynthesized seed MgO-NPs were characterized by ultraviolet-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), scanning electron microscopy (SEM) with energy-dispersive X-ray diffraction (EDX), and Fourier-transform infrared spectroscopy (FT-IR). These methodological approaches demonstrated their capacity to synthesize crystalline and aggregated MgO-NPs with a size average of 13.38 ± 0.16 nm. The biogenic MgO-NPs were found to have a significant quantity of total phenolic contents (TPC) and total flavonoid contents (TFC), indicating the existence of phenol and flavonoid-like components. The biogenic MgO-NPs demonstrated a significant free radical scavenging effects compared to different standards as measured by the inhibition of free radicals produced in 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS•+), and Nitric oxide (NO) scavenging methods; they also exhibited higher ferric ion reducing capacity in FRAP assay. Moreover, they were found to be non-toxic in cytotoxic assessment. Pretreatment of Wistar Albino rats with seed MgO-NPs resulted in a significant reduction of cardiac biomarkers, i.e., cardiac Troponin-I (cTnI), creatine kinase (CK-MB), and aspartate aminotransferase (AST). The seed MgO-NPs were more successful in reducing lipid levels. The results of the mRNA expression analysis showed that seed MgO-NPs efficiently reduced the expression of the apoptotic genes p53 and Caspase-3 while restoring the expected levels of SOD gene expression. The histopathological observations were primarily focused on the disruption of cardiac fibers and myofibrillar disintegration, which are consistent with the biochemical findings. Therefore, our research suggests that MgO-NPs derived from the seeds of Tamarindus indica as a powerful antioxidant; the administration may be effective in protecting the heart from DOX-induced cardiotoxicity.

Abstract
Relapsing polychondritis is a rare autoimmune disorder of unknown etiology, which can affect multiple organs. It usually presents with involvement of elastic cartilage of ear and nose and involvement of other organs like kidney and central nervous system. Here, we report a case of 60-year-old man, who initially presented with fever, polyarthritis, erythema nodosum and painful swelling and redness of both external ears admitted in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 13th December 2019. Two days after hospitalization, he developed sudden onset of proptosis with ophthalmoplegia. After evaluation, he was diagnosed as relapsing polychondritis with haemophagocytic lymphohistiocytosis and was treated with high dose prednisolone. His clinical condition and laboratory parameters significantly improved after treating with prednisolone during follow up.

Abstract
Febrile neutropenia (FN) is a frequently occurring treatment-related complication with significant morbidity and mortality for childhood acute leukemia. Early diagnosis and assessment of severity are essential steps for early comprehensive treatment to reduce FN-related morbidity and mortality. Biomarkers like C-reactive protein (CRP) and procalcitonin (PCT) can be used to assess and predict the bacterial infection in children with febrile neutropenia. The objective of the study was to determine the role of procalcitonin and CRP as a biomarker for prediction of bacterial infection in children with FN in acute leukemia. This prospective observational study was conducted in the Department of Pediatric Hematology and Oncology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from August 2020 to July 2021. Total 58 Children with acute leukemia aged 1 to <18 years with FN were analyzed in this study. A proper history and thorough physical examination were carried out. The blood sample was sent for biomarkers (Procalcitonin and CRP) within 24 hours of the onset of FN and other investigations, such as Complete blood count, Blood C/S, Urine R/E and C/S. Metabolic workup (SGPT, Serum Creatinine, Serum Electrolytes, Serum Ca+) was also done in every patient. Stool R/E & C/S, Chest X-ray, Wound swab for C/S were done when the patient presented with diarrhoea, cough, respiratory distress and focal sepsis respectively. In this study, the mean age of the patients was 6.62±4.07 years (1.10-16.0 years) and 34 patients (58.6%) were male. In 65.5% of patients, localizing signs of infection were not identified. Of the 58 patients, 12 patients (20.7%) showed positive blood culture and 2 patients (3.4%) showed positive urine culture. Klebsiella spp (41.0%) was the most frequent organism isolated followed by Acinetobacter (17.0%), Pseudomonas (17.0%) and E. coli (17.0%). The median PCT levels were significantly higher in patients with bacterial infection than patients without bacteremia (26.10μg/l versus 0.78μg/l, p=0.002) and PCT level >2μg/l was significantly associated with bacteremia. The median CRP levels in the bacteremia and without-bacteremia patients were 137.4mg/L and 54.17mg/L, respectively (p=0.036). In direct comparisons, PCT showed better overall performance than CRP with the AUC being 0.797 (95% CI 0.651-0.943) for PCT and 0.697 (95% CI 0.54-0.855) for CRP in predicting the bacterial infection. PCT and CRP both are useful biomarkers for the prediction of bacteremia, but PCT may be a superior early biomarker as compared to CRP to predict bacterial infection in children with febrile neutropenia in acute leukemia.

Abstract
Paroxysmal nocturnal haemoglobinuria (PNH) is a rare disorder of hematopoietic stem cells. The occurrence of PNH in a patient with systemic lupus erythematosus (SLE) is even rarer. One such presentation was seen in a 19 years old woman who presented with fever, multiple joint pain, photosensitivity, oral ulcer, hair loss and was diagnosed as a case of SLE and was admitted in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh on 7th February 2019. Subsequently she developed progressive anaemia and passing of dark colored urine. Flow cytometry analysis showed PNH clone within red cells. We report this case so that clinicians are aware about this association between PNH and SLE. Informed written consent was obtained from the patient for the publication of this case report, the copy of which is available with the authors.

Abstract
Lasia spinosa (L.) Thwaites is a medicinal plant of enormous traditional use with insufficient scientific evidence. This research screened the antioxidative effect of L. spinosa extracts by measuring the total phenolic content, total flavonoid content, DPPH free radical scavenging activity, ABTS scavenging activity, Iron-chelating activity, and Ferric reducing power followed by an evaluation of in vivo cardioprotective effect in doxorubicin-induced Wistar Albino rats. Phytochemical characterization was made by Gas Chromatography-Mass Spectroscopic analysis. L. spinosa showed an excellent antioxidative effect while methanol leaf extract (LSM) was found to be more potent than ethyl acetate leaf extract (LSE) in scavenging the free radicals. Intraperitoneal injection of doxorubicin caused a significant (P < 0.001) increase in lactate dehydrogenase (LDH), creatine kinase (CK-MB), C-reactive protein (CRP), and Cardiac troponin I. Pretreatment with orally administrated (LSM100 and LSM200 mg/kg b.w.) daily for 10 days showed a decrease in the cardiac markers, lipid profiles, especially triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), and an increase of high-density lipoprotein (HDL) compared to the disease control group. LSM200 was found to significantly (P < 0.05) decrease the levels of CK-MB and LDH. It also restored TC, TG, and LDL levels compared to the doxorubicin-induced cardiac control group. The protective role of LSM was further confirmed by histopathological examination. This study thus demonstrates that L. spinosa methanol extract could be approached as an alternative supplement for cardiotoxicity, especially in the chemical-induced toxicity of cardiac tissues.

Abstract
Tuberculosis (TB) is one of the major public health issues in many developing nations especially in Bangladesh. Though most focus is being directed towards mortality and incidence rate, the changes in morbidity and other health status parameters are not been well considered. The aim of the study was a comprehensive assessment of patients with pulmonary tuberculosis by measuring patient's quality of life which may lead to better outcome in patients' health, infection surveillance and prevention programs. This prospective study was conducted in the department of Respiratory and Internal Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from September 2015 to March 2017. The quality of life scores of 61 smear positive pulmonary tuberculosis cases were measured by validated Bangla version of SF-36 questionnaire before or at the starting of treatment, after the initial phase and at the end of treatment. Then the score was compared with those of 75 healthy matched controls. The changes of the quality of life with the stage of treatment and with socio-demographic variables were assessed. Before treatment, all domains of HRQoL of the pulmonary TB patients were significantly lower than those of the control group (p<0.001). At the end of six-month treatment period, HRQoL of the pulmonary TB patient had significantly increased compared to before treatment (p<0.001). There was no significant difference of scores after six months of treatment with that of control (p>0.05). The lowest score in tuberculosis patients was related to general health perception and vitality. Patients with low socio economic status, low educational level, prolonged disease duration and increased number of symptoms had lower HRQoL scores.

Abstract
Plants are an entity essential to the function of the biosphere as well as human health. In the context of human health, this research investigated the effect of Lasia spinosa (Lour) leaf methanolic extracts (LSML) on antioxidative enzymes and gene expression as well as biochemical and histological markers in a streptozotocin (STZ)-induced diabetes model. Fructose-fed streptozotocin (STZ)-induced diabetic animals were subjected to a four-week intervention followed by the assessment of the animal’s blood and tissues for enzymatic, biochemical, histological, and genetic changes. LSML-treated groups were shown to decrease plasma glucose levels and improve body and organ weights compared to the untreated group in a dose-dependent manner. At the doses of 125 and 250 mg/kg b.w., LSML were able to normalize serum, hepatic, and renal biochemical parameters and restore the pancreas, kidney, liver, and spleen tissue architectures to their native state. A considerable increase (p < 0.01) of liver antioxidant enzymes CAT, SOD, GSH, and a decrease of MDA level in LSML-treated groups were found at higher doses. The improved mRNA expression level of antioxidant genes CAT, SOD2, PON1, and PFK1 was also found at the doses of 125 mg/kg and 250 mg/kg BW when compared to untreated control groups. The results demonstrate that LSML impacts the upregulation of antioxidative gene expressions, thus improving the diabetic complications in animal models which need to be affirmed by compound-based antioxidative actions for therapeutic development.

Abstract
Natural biometabolites of plants have been reported to be useful in chronic diseases including diabetes and associated complications. This research is aimed to investigate how the biometabolites of Lasia spinosa methanol stem (MEXLS) extract ameliorative diabetes and diabetes-related complications. MEXLS was examined for in vitro antioxidant and in vivo antidiabetic effects in a streptozotocin-induced diabetes model, and its chemical profiling was done by gas chromatography-mass spectrometry analysis. The results were verified by histopathological examination and in silico ligand-receptor interaction of characterized natural biometabolites with antidiabetic receptor proteins AMPK (PDB ID: 4CFH); PPARγ (PDB ID: 3G9E); and mammalian α-amylase center (PDB ID: 1PPI). The MEXLS was found to show a remarkable α-amylase inhibition (47.45%), strong antioxidant action, and significant (p < 0.05) decrease in blood glucose level, serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), low-density lipoprotein (LDL), urea, uric acid, creatinine, total cholesterol, triglyceride (TG), liver glycogen, creatinine kinase (CK-MB), and lactate dehydrogenase (LDH) and increase in serum insulin, glucose tolerance, and high-density lipoprotein (HDL). Rat’s pancreas and kidney tissues were found to be partially recovered in histopathological analyses. Methyl α-d-galactopyranoside displayed the highest binding affinity with AMPK (docking score, −5.764), PPARγ (docking score, −5.218), and 1PPI (docking score, −5.615) receptors. Data suggest that the MEXLS may be an exciting source to potentiate antidiabetic activities affirming a cell-line study.

Abstract
There is a knowledge gap about the rehabilitation system for the persons with spinal cord injury (SCI). A rehabilitation scenario is necessary to conduct a national community survey in conjunction with the International Spinal Cord Injury Community Survey (InSCI) in order to gather data on the lived experiences of people with SCI, to map out the health and rehabilitation system of Bangladesh, it's demographic characteristics, accessible resources and rehabilitation challenges. Information for this narrative report was acquired through a structured questionnaire, which was supplemented by an online search of agencies, government websites, rehabilitation-related organizations and published papers during the period of March 2020 to April 2021. Bangladesh is a developing country with a vast population and a developing health care system. Representative government and non-government rehabilitative care settings a total of sixteen survey replies (n=16) were obtained. During the year 2019, a total of 1035 people with SCI were seen. The majority of patients with SCI were hospitalized by a non-government facility (38.65%), whereas the two main public general hospitals consulted roughly 30.0% of people with SCI. The rehabilitation team leader in the majority of the facilities (93.75%) was a physiatrist, but just a few had a full complement of rehabilitation professionals and only 12.5% of settings provide community care. Indoor rehabilitation facilities, equipment and a competent rehabilitation staff are not available at many of the tertiary care facilities including National Trauma Institute (NITOR), where most of the SCI report first after the trauma. A consistent and nationwide data source is unavailable and the majority of the available SCI research publications are hospital-based demographic studies in Bangladesh. SCI was commonly due to work-related trauma in young male manual laborers due to fall from height or road traffic accidents. The country faces multiple challenges in rehabilitation of people with SCI regarding triage, a referral system development, infrastructure and shortage of expert human resources in addition, currently there is no three-tier rehabilitation care continuum available. Keeping pace with the transition to a developed country by 2041, the Bangladesh health sector also has to be oriented to face the focused challenge of caring for people with SCI. As recommended by WHO Rehabilitation 2030 initiatives, establishment of an SCI dedicated national institute and escalation of number of related specialists such as trauma and orthopedic surgery, spinal neurosurgery and physical rehabilitation medicine, skilled professionals such as rehabilitation nurses, therapists, case managers and social workers to work in a team required for specialized care of SCI.

Abstract
Medicinally active compounds in the flavonoid class of phytochemicals are being studied for antiviral action against various DNA and RNA viruses. Quercetin is a flavonoid present in a wide range of foods, including fruits and vegetables. It is said to be efficient against a wide range of viruses. This research investigated the usefulness of Quercetin against Hepatitis C virus, Dengue type 2 virus, Ebola virus, and Influenza A using computational models. A molecular docking study using the online tool PockDrug was accomplished to identify the best binding sites between Quercetin and PubChem-based receptors. Network-pharmacological assay to opt to verify function-specific gene-compound interactions using STITCH, STRING, GSEA, Cytoscape plugin cytoHubba. Quercetin explored tremendous binding affinity against NS5A protein for HCV with a docking score of - 6.268 kcal/mol, NS5 for DENV-2 with a docking score of - 5.393 kcal/mol, VP35 protein for EBOV with a docking score of - 4.524 kcal/mol, and NP protein for IAV with a docking score of - 6.954 kcal/mol. In the network-pharmacology study, out of 39 hub genes, 38 genes have been found to interact with Quercetin and the top interconnected nodes in the protein-protein network were (based on the degree of interaction with other nodes) AKT1, EGFR, SRC, MMP9, MMP2, KDR, IGF1R, PTK2, ABCG2, and MET. Negative binding energies were noticed in Quercetin-receptor interaction. Results demonstrate that Quercetin could be a potential antiviral agent against these viral diseases with further study in in-vivo models.

Abstract
Rheumatoid arthritis (RA) patients have substantial functional disability which poses a significant impact on the quality of life (QoL). So, this study aims to assess the QoL of RA patients by the Short Form Health Survey-36 (SF-36) questionnaire. Total sixty-two (62) rheumatoid arthritis patients were included in this cross-sectional observational study and were performed in the Department of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from August 2018 to September 2019 according to selection criteria. A Bengali validated version of Medical Outcomes Study-36: Item Short Form Health Survey (SF-36) questionnaire was used to assess QoL. Among the sixty-two (62) patients, mean age was 44.18±12.14 years with female preponderance (77.4%). About one-fifth of the patients (19.4%, n=12) were illiterate and the majority (71.0%, n=44) were housewives. Amongst all, 53.2% (n=33) had monthly family income >20,000 taka. Forty percent (n=25) had a disease duration of 1 to 5 years. According to Disease Activity Score Sheet 28 (DAS-28), 36(58.1%) patients had moderate disease activity and 26(41.9%) patients had high disease activity. Among the 8 domains, the mental health domain had the highest score (42.77±13.78) and the role physical domain had the lowest (35.89±15.43). Male, literate patients with higher income had relatively better QoL. Patients with prolonged disease, high disease activity and irregular taking of Disease Modifying Anti-Rheumatic Drugs (DMARDs) had poor quality of life. A significant negative correlation was present between SF-36 scores and the DAS-28 scores (r = -0.803, p<0.001). Rheumatoid arthritis had a relatively poor quality of life regarding both physical and mental health components, but the physical health component was predominantly affected.

Abstract
In recent years, diastolic dysfunction is an evolving context. Presence of left ventricular diastolic dysfunction (LVDD) indicates a poor prognosis in patients with an ACS and chronic coronary artery diseases. This study evaluated the association of LVDD and angiographic severity of CAD in patients with non-ST elevation myocardial infarction (NSTEMI). This cross-sectional analytical study was carried out in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh, during the period of April 2017 to March 2018. A total of 120 NSTEMI patients undergoing coronary angiogram (CAG) during index hospitalization were included in the study. All patients underwent transthoracic echocardiography before they underwent CAG on different days. Presence (Group I, n=65) and absence of LVDD (Group II, n=55) was established by echocardiography. Severity of CAD was assessed by Vessel score and Leaman score. Association of traditional risk factors (smoking habit, hypertension, diabetes mellitus, dyslipidemia and family history of CAD) with severity of CAD was investigated. Vessel score showed coronary artery obstruction (CAO) was present in 62(95.4%) patients in Group I and 35(63.6%) patients in Group II, single vessel was involved in 17(27.4%) patients while multi vessel in 45(72.6%) patients was found in Group I. On the contrary 27(77.1%) single vessel patients and 8(22.9%) multi vessel patients were found in Group II. Positive Leaman score was significantly higher in Group I, 62(95.4%) than that of Group II, 35(63.6%) which is statistically significant (p<0.001). This study showed a positive correlation between LVDD and CAD severity in terms of vessel score and Leamanscore. This study also demonstrates that the severity of vessel score and Leaman score was higher in the higher grade of diastolic dysfunction. The present study concludes that LVDD is associated with angiographically severe CAD in patients with NSTEMI.

Introduction
Chronic heart failure (CHF) prevails as one of the major cardiovascular diseases in lower-middle-income countries (LMICs) like Bangladesh. Home-Based Cardiac Rehabilitation (HBCR) is a cost-effective method of secondary prevention of chronic heart failure which, if provided, might not only improve the health status of the patients but might also reduce the financial and hospitalization burden on the health care system of these countries. The study aims to assess the scope and benefits of HBCR in such low resource settings.
Purpose
The study evaluates the effect of telephone-monitored HBCR exercise programme in improving the functional capacity and quality of life (QoL) in patients of CHF with reduced ejection fraction due to ischemic heart disease (IHD).
Method
This self-controlled interventional study was conducted from August 2019 to July 2020 at a heart failure clinic, a tertiary healthcare centre in Bangladesh. A total of 115 patients of CHF with ejection fraction <40% and in NYHA class II and III were included in the study according to selection criteria. The functional capacity of the patients was evaluated by NYHA classification and 6-minute walk test. The quality of life of the patients was evaluated by Minnesota Living with Heart Failure Questionnaire (MLHFQ). All patients were advised to perform HBCR exercise as per recommended guideline and were telephone-monitored 2-weekly. After the 3-months study period, the participants were divided into compliant and partial compliant groups based on their adherence to the guideline. Repeat evaluation of patients' condition was carried out. Results were then compared within the groups and data was analyzed through appropriate statistical methods.
Results
Significant improvement of NYHA class (p<0.05), and 6-minute walk test distance (6MWTD) (1102.01±215.90 feet vs 1243.30±217.86 feet; p<0.001) were noticed after the rehabilitation programme. Improvement of total MLHFQ score was also observed (35.53±14 vs 28.22±12.84; p<0.001) at 3-months follow up. The functional capacity and quality of life of the patients in both the compliant and partially compliant groups showed significant improvement after the rehabilitation programme (p<0.001); though no difference was found in the indicators when compared between compliant vs partially compliant groups after rehabilitation except for 6MWTD (1302.86±219.61 feet vs 1230.71±212.284 feet, p<0.001).
Conclusion
From the results, it can be concluded that any amount of routine exercise tends to improve quality of life and symptoms in patients of chronic heart failure with reduced ejection fraction. However, to achieve the best effect in functional capacity and overall health status, the addition of a structured exercise programme like HBCR can be beneficial for proper rehabilitation in low resource settings. Further validation of the results is recommended through randomized control trials in larger study groups.

Abstract
Since ancient times, plants have been used as green bioresources to ensure a healthier life by recovering from different diseases. Kattosh (Lasia spinosa L. Thwaites) is a local plant with various traditional uses, especially for arthritis, constipation and coughs. This research investigated the effect of Kattosh stem extract (LSES) on streptozotocin-induced damage to the pancreas, kidney, and liver using in vitro, in vivo and in silico methods. In vitro phytochemical, antioxidative and anti-inflammatory effects of LSES were accomplished by established methods followed by antidiabetic actions in in vivo randomized controlled intervention in STZ-induced animal models for four weeks. In an in silico study, LSES phytocompounds interacted with antidiabetic receptors of peroxisome proliferator-activated receptor-gamma (PPAR, PDB ID: 3G9E), AMP-activated protein kinase (AMPK, PDB ID: 4CFH) and α-amylase enzyme (PDB ID: 1PPI) to verify the in vivo results. In addition, LSES showed promising in vitro antioxidative and anti-inflammatory effects. In contrast, it showed a decrease in weekly blood glucose level, normalized lipid profile, ameliorated liver and cardiac markers, managed serum AST and ALT levels, and increased glucose tolerance ability in the animal model study. Restoration of pancreatic and kidney damage was reflected by improving histopathological images. In ligand-receptor interaction, ethyl α-d-glucopyranoside of Kattosh showed the highest affinity for the α-amylase enzyme, PPAR, and AMPK receptors. Results demonstrate that the affinity of Kattosh phytocompounds potentially attenuates pancreatic and kidney lesions and could be approached as an alternative antidiabetic source with further clarification.

Abstract
Mitochondrial disorders are clinically heterogeneous, resulting from nuclear gene and mitochondrial mutations that disturb the mitochondrial functions and dynamics. There is a lack of evidence linking mtDNA mutations to neurodegenerative disorders, mainly due to the absence of noticeable neuropathological lesions in postmortem samples. This review describes various gene mutations in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, and stroke. These abnormalities, including PINK1, Parkin, and SOD1 mutations, seem to reveal mitochondrial dysfunctions due to either mtDNA mutation or deletion, the mechanism of which remains unclear in depth.

Abstract
This study aims to explore physician's perceptions about the use of Personal Protective Equipment (PPE), COVID prevention, and management during the COVID pandemic since knowledge on these might explain the reason behind infection and death of physicians in Bangladesh at an unexpected rate. This cross-sectional study was conducted based on an online questionnaire on 346 physicians (n=346) by the Department of Gastroenterology of Mymensingh Medical College Hospital, Bangladesh from 15th July 2020 to 14th September 2020. Physicians of different health care facilities across Bangladesh were invited to take part. Knowledge on specific points of the questionnaire was evaluated, scored, and compared between different groups by Independent sample t-test. Mean knowledge score between the respondents working up to 8 hours and beyond 8 hours per day was 17.28±1.28, 16.90±1.40 respectively (p=0.03). Mean knowledge score observed between graduate and post-graduate physicians and work experience of 5 years and beyond 5 years were 17.26±1.36 vs. 17.16±1.27; (p=0.40), 16.87±1.75 vs. 17.27±1.21; (p=0.11) respectively. Physician's safety should be first concern that is highlighted through proper use of PPE and prevention of COVID. Patient management skills would be better if physicians are trained well on infection prevention and control which in turn will reduce infection and death of physicians.

Abstract
NSTEMI patients, in comparison to STEMI patients, are more at risk of bleeding, access site complication and MACE after PCI during index hospitalization. Because they get, multiple adjuvant anti-thrombotic agents before PCI than do the STEMI patients undergoing primary PCI. Transradial access (TRA) is proven to decrease those adverse in-hospital outcomes compared to transfemoral access (TFA) in STEMI patients. But very few studies were conducted in this regard considering NSTEMI patients. We observed prospectively the adverse in-hospital outcomes of total 180 NSTEMI patients who had undergone PCI through TRA (Group I = 80) and TFA (Group II = 100) during index hospitalization between October 2017 to September 2018 in National Institute of Cardiovascular Disease (NICVD), Dhaka, Bangladesh. Samples were selected purposively. Patients were followed up 2 hours after PCI and thereafter every day until discharge. Demographic and risk factor variables were almost same in both groups. TRA, compared with TFA, yielded less major bleeding (0% versus 3%, p=0.12) which was statistically non-significant. Minor bleeding was significantly less in Group I (2.5% versus 13.0%, p=0.04). Overall bleeding was also significantly less in Group I (2.5% and 10.0%; p=0.002). Access site complication was non-significantly less in Group I (0% versus 1%, p=0.91). TRA caused non-significant reduction in MACE (2.5% versus 5%; p=0.38) but significant reduction of total adverse in-hospital outcome (5% versus 20%, p=0.006%). In this study TRA seems to have less adverse in-hospital outcome than TFA in NSTEMI patients undergoing PCI during index hospitalization.

Abstract
Thyroid swellings are common clinical problem throughout the world and also in Bangladesh. Most of thyroid swellings are multinodular, but a good percentage is solitary thyroid nodule. There is no robust, feasible method for malignancy differentiation has not been well established. The study evaluated thyroid nodules for risk of malignancy and compared history, clinical, sonographic features and FNAC findings with histopathology. This was a cross sectional study on 160 consecutive subjects of thyroid nodules done in the department of ENT and Head Neck Surgery of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh during from July 2018 to December 2019. All patients were admitted and diagnosed by detail history, clinical examination, investigations and underwent thyroidectomy. Detailed history, clinical examination, ultrasonographic finding and FNAC variables were documented retrospectively and a mathematical model was established for malignancy prediction. In this study mean age of the patients of thyroid nodules was 37.54±11.49 years and majority of the patients were within 21-40 years of age. Frequency of thyroid nodules is more in female with male female ratio 1:7. Most of the thyroid nodules appeared in this study within 0-2 years (61.9%). In this series of thyroid nodules constituted 88.1% firm, 8.8% hard, 3.1% cystic. Among the patients 89(55.6%) cases have solitary thyroid nodule and 71(44.4%) cases have multinodular goitre Majority of the nodules were warm 57.5% followed by cold 42.5%. FNAC showed nodular goitre 72.5%, Follicular neoplasm 1.3%, Papillary carcinoma of thyroid 7.5%, colloid goitre 9.4%, suspicious papillary carcinoma 3.8% and lymphocytic thyroiditis 1.3%. In this study out of 85 solid nodule, 69(81.18%) were benign and 16(18.82%) was malignant and out of 3 cystic nodule 3(100%) were benign. In this study most of the benign and malignant nodules were predominantly solid. Study showed the malignancy is significantly (p=0.001) more in solid than cystic nodules. Final diagnosis in this study was done on the basis of histopathological reports. Out of 160 patients, histopathologically benign lesion was 120(75%) and malignant was 40(25%). Among malignant cases 36(22.5%) cases were papillary carcinoma, 1 case was medullary carcinoma and 3 cases were follicular carcinoma.

Abstract
Recent COVID-19 pandemic has changed health resource disposal plan and urged relocation of work force to defend the world from devastation of this emerging disease. This cross-sectional observational study aims to categorize and rationalize COVID-19 testing of all patients attending flu corner of One Stop Service (OSS) in the department of Emergency and Casualty (E&C) in Mymensingh Medical College Hospital (MMCH) during 15th April 2021 to 14th May 2021 on 2627 patients as per inclusion and exclusion criteria. Out of 2627 patients 920(35%) were symptomatic cases and 1707(65%) attended for testing without symptom. Out of 920 symptomatic cases 175(19%) were confirmed COVID-19 cases. Among the confirmed cases 38(21.71%) was admitted whereas, from suspected cases 100(13.42%) got admitted, remaining patients from both categories were advised for home isolation. Coverage and justification of COVID-19 testing should be done precisely to ensure proper disease control and COVID care during this pandemic.
