RESUMEN
Covid-19 has become a pandemic since its emergence in Wuhan, China. It involves Gastro intestinal (GI) system and diarrhea is recognized as an important symptom. Diarrhea is also associated with disease severity. This study was conducted to see the prevalence of diarrhea in Covid-19 positive patient and its relation with disease severity. Prospective observational study done among consecutive Covid-19 positive patient of both sex admitted in Mugda Medical College Hospital in Dhaka from February 2021 to April 2021. Informations were collected by face to face interview and severity was assessed on bedside. Among 166 Covid-19 positive patient 40.0% developed diarrhea. Mean age of the diarrheal patients was 44.21±14.40. Women affected more than men (51.0% versus 49.0%). In majority patient (62.0%) diarrhea persist for 3-7 days and majority had frequency of bowel movement 3-5 times per day. Regarding Bristol stool type 47.0% had stool type 6 followed by stool type 7(43.0%) and stool type 5(10.0%). Half of the diarrheal patient (48.0%) had severe pneumonia. Severe pneumonia is significantly more common in non-diarrheal patients (65.0%) than in diarrheal patient (35.0%) (p=0.007). This study reflects that a large number of Covid-19 positive patients developed diarrhea. Half of the diarrheal patients had severe pneumonia. But severe pneumonia is significantly common in non-diarrheal patient than diarrheal patients.

ncreasing trend in antimicrobial resistance and failure of chemically synthesized antibiotics lead to discover alternative methods for the treatment of bacterial infections. Various medicinal plants are in use traditionally and their active compounds can be further applied for treatment of bacterial diseases. This study was designed to determine the antibacterial activity of Punica granatum (P. granatum L.) (pomegranate) peel extract against Enterobacteriaceae [Escherichia coli (E. coli), Salmonella Typhimurium (S. Typhimurium) and Shigella Dysenteriae (S. Dysenteriae)] and gram-positive bacterium [Staphylococcus aureus (Staph aureus)]. Methanolic extract of P. granatum L. peel was prepared by Soxhlet apparatus method. Total flavonoid and phenolic contents from the extract were determined by High Performance Liquid Chromatography (HPLC). The antibacterial activity of P. granatum L. peel extract was evaluated through agar well diffusion method. HPLC showed the range of phenolics (gallic acid, caffeic acid, benzoic acid, cinnamic acid) and flavonoid compounds. The chemical structures of flavonoid and phenolics found in the methanolic extract of P. granatum L. peel have been reported for the first time. The methanolic peel extract (50 ul) of yellow P. granatum L. showed 26, 10, 10 and 9mm zones of inhibition (ZOI) against S. aureus, S. Typhimurium, S. Dysenteriae and E. coli, respectively.

This prospective study was conducted to find the rate of deep and risk factors associated with vein thrombosis following major abdominal surgery in Sylhet MAG Osmani Medical College Hospital from 1st November 2017 to 30th April 2018. Total 103 patients aged above 20 years both male and female who got admitted in Department of Surgery, Sylhet MAG Osmani Medical College Hospital, Sylhet for their disease requiring routine and emergency major abdominal operation during the study period and fulfilling the inclusion and exclusion criteria were selected in this study. Informed written consent was obtained from the patients after full explanation of the purpose of the study. After full investigations and proper preparation of each patient for operative procedure major abdominal surgery were done. Peroperative findings were noted and post-operative period were followed up routinely. Duplex scanning was done on 3rd POD in all cases. The age of the patients ranged from 25 to 74 years with the mean age of 49.5±13.8 years. There were 60(58.3%) male and 43(41.7%) female. Deep vein thrombosis (DVT) developed in 5(4.9%) of cases and not developed in 98(95.1%) cases. All the five cases were confirmed by color duplex scan. DVT was detected in 2(3.3%) of the 60 males and 3(7.0%) of the 43 females undergoing major general surgical procedures. Among 63 patients in whom the duration of surgery was up to 2 hours, none developed DVT, while among the 40 patients in whom the duration of surgery lasted more than 2 hours, 5(12.5%) developed DVT. Among 23 patients in whom the surgery for malignancy was done, 4(17.4%) developed DVT, while among the 80 patients in whom surgery for non-malignancy, 1(1.2%) developed DVT. The Incidence of DVT in patients undergoing major abdominal surgery is 4.9%. Patients undergoing major abdominal surgery for malignancy and duration of operation greater than 2 hours have higher risk of developing DVT. But there is no significant increase in risk of development of DVT relation to age and sex; and also in patients on oral contraceptives, diabetes mellitus, obesity and smoking. Clinical findings alone cannot be relied upon for the diagnosis of DVT. The study has to be continued with larger sample size to get statistically significant results.

Human brucellosis is a neglected zoonotic problem worldwide with a high degree of morbidity in humans and is mostly overlooked due to other febrile conditions. The aim of this study was to evaluate the sero-prevalence and risk factors of human brucellosis among subjects living in Punjab, Pakistan. In this cross-sectional study, human blood samples were collected from seven districts of Punjab, Pakistan. Information regarding personal data, demographic data and potential risk factors was collected through a structured questionnaire. Detection of anti-Brucella antibodies was done through Rose Bengal Plate Test (RBPT) and Enzyme Linked Immunosorbent Assay (ELISA). Descriptive analysis, Chi square test and Odds ratio was applied using STATA software version 12. The sero-prevalence of human brucellosis was 13.13% with significantly higher percentage in males 17.23% and age group 25-40 years 16.50% (P=< 0.001). The demographic factors positively associated with human brucellosis were lack of education (P = 0.003; OR = 1.85) and farming as an occupation (P =<0.001; OR = 2.50) Similarly, among the risk factors studied, keeping animals at home (P =<0.001; OR = 2.03), slaughtering of animals (P =<0.001; OR = 15.87) and consuming raw milk (P =<0.001; OR = 5.42) were the factors strongly connected with human brucellosis. A massive awareness should be given to livestock farmers and individuals directly linked to animals regarding risk factors and transmission of brucellosis. Consumption of unpasteurized milk and its products should be condemned to curtail this neglected disease.

INTRODUCTION: Kidney transplant (KT) directors are general surgeons or urologists. All KT centers must meet established performance standards. However, it has not been established if general surgery and urology led programs have disparate outcomes. METHODS: Transplant outcomes and donor-recipient characteristics by director training were investigated. Organ Procurement and Transplantation Network (OPTN) directory, program websites were analyzed for surgical director demographics. Scientific Registry of Transplant Recipients (SRTR) 1-year kidney survival and deceased donor (DD) wait-time rankings were evaluated. A retrospective analysis of 142 157 KT recipients from 2010 to 2019 was performed using the United Network for Organ Sharing (UNOS) database. RESULTS: One hunderd and seventy three (90.6%) KT programs were led by general surgeons. There were no significant differences in gender, ethnicity, region, credentials, or fellowship completion. Recipients undergoing KT with urology led programs were older (P = .002) and had longer wait-times (P < .001). These centers used higher KDPI (.47 vs. .45, P < .001) and higher HLA mismatch (3.92 vs. 3.89, P = .02) kidneys. Urology led centers utilized living donors less frequently (32.1% vs. 35.8%, P < .001) and had longer CIT (15.44 vs. 12.21, P < .001). Both had similar SRTR ranking of 1-year survival and DD wait-time. CONCLUSION: Most directors were general surgeon. Patient outcomes did not differ by transplant director training. Urologists represent a viable option for KT leadership and recruitment should be encouraged.

Syphilis is a sexually transmitted disease and its actual prevalence among Pakistani blood donors is currently unknown. A cross sectional study was conducted at different district healthcare hospitals of Punjab, Pakistan with an aim to evaluate the prevalence and risk factors associated with syphilis in blood donors using immunochromatographic test (ICT) and enzyme linked immunosorbent assay (ELISA). A total (n=1200) blood samples were collected from donors aged 18-65 years. All the information regarding personal data, demographic data and risk factors was collected via structured questionnaire. On the basis of ICT and ELISA, the overall prevalence of syphilis was 3.91% among blood donors. The demographic factors positively linked with syphilis were age (P= 0.000; Odds ratio, OR= 7.18; 95% confidence interval CI= 2.816-18.295) and education status (P= 0.000; Odds ratio, OR= 12.33; 95% confidence interval CI= 3.469-43.849) of donors. Similarly among the risk factors analyzed, marital status (P= 0.012; Odds ratio OR= 2.251; 95% confidence interval CI= 1.206- 4.202) and blood transfusion history (P= 0.030; Odds ratio OR= 1.981; 95% confidence interval CI= 1.083-3.623) were also strongly associated with syphilis. We emphasized the importance of promoting preventive measures for syphilis. The syphilis diagnosis should not be based on a single test. The present study indicates that higher prevalence is alarming for blood donors in Pakistan. Stringent donor screening is highly recommended to ensure maximum safe blood transfusion.

AIMS: To determine the occurrence, diversity, antibiotic resistance and biofilm formation of Vibrio parahaemolyticus isolated from marine fishes in Bangladesh. METHODS AND RESULTS: A total of 80 marine fishes were obtained from the local markets and examined for the presence of V. parahaemolyticus. All the isolated V. parahaemolyticus were characterized for the presence of virulence markers, thermostable direct hemolysin (TDH) or thermostable direct hemolysin related hemolysin (TRH). Isolates were serotyped and further characterized by enterobacterial repetitive intergenic consensus sequence PCR (ERIC-PCR) typing to analyse the genetic diversity. Moreover, biofilm formation and antibiotic resistance patterns were also determined. About 63·75% (51/80) of the tested marine fishes were contaminated with V. parahaemolyticus. From the contaminated fishes, 71 representatives V. parahaemolyticus were isolated and none of them harboured tdh and trh virulence genes. Nine different O-groups and seven different K-types were found by serological analysis and the dominant serotype was O5:KUT. In ERIC-PCR analysis, eight clusters (A-H) were found and the most common pattern was A (46·5%). All of the isolates were resistant to ampicillin and 78·9% of isolates were resistant to streptomycin. The highest biofilm formation was found at 37°C compared to 25°C and 4°C. CONCLUSION: Diverse V. parahaemolyticus are present in marine fishes in the local market of Bangladesh with antibiotic-resistant properties and biofilm formation capacity. SIGNIFICANCE AND IMPACT OF THE STUDY: The widespread prevalence of diverse V. parahaemolyticus in marine fishes is an issue of serious concern, and it entails careful monitoring to ascertain the safety of seafood consumers.

RESUMEN
This prospective comparative study was done to compare the outcome of stapled closure of the duodenal stump with hand-sewn closure during gastric resection in terms of total operating time, postoperative duodenal stump leakage, postoperative hospital stay, and surgical cost. This study was conducted from January 2013 to August 2014. Patients who were admitted to the Department of Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh with the indication of distal or total gastrectomy were included in the study. A total of 32 patients were enrolled in this study with 16 in each group, they were divided either into Group I (Hand Sewn) or Group II (stapling). Mean±SD age of Group I was 53.38±8.69 and Group II was 50.88±9.56 (p=0.445). Male patients were predominant than the female with a male: female ratio being 3.57:1. Mean±SD total operating time was 154.38±16.32 minutes and 136.88±17.40 minutes in Group I and Group II respectively (p=0.001). In Group I, 2(12.5%) patients and in Group II, 1(6.3%) patient had duodenal stump leakage which showed no statistically significant difference (p=0.999). Postoperative hospital stay had no statistically significant difference (p=0.923). The surgical cost had a significant difference (p=0.001) which is more in Group II. This study showed there was a significant reduction in total operating time but there was no significant difference in occurring of duodenal stump leakage or postoperative hospital stay. However, use of stapler hastens the surgeon's job and it relieves extra pressure of them.

The magnitude of case management of indeterminate thyroid nodule is very difficult and controversial. In addition there is recent evidence that the incidence of follicular lesion may be increasing that will prove to be follicular cancer. This prospective observational study was done in the department of Surgery at Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from February 2016 to January 2017 to investigates the rate of malignancy and inability of demographical, clinical and sonographic data to predict malignancy in indeterminate nodules and the unreliability of intraoperative frozen section biopsy with the scope of determining the need for total thyroidectomy in these patients. The study population consisted of 40 cases presenting indeterminate nodules (Thy3): females (80%) and males (20%) with a mean age of 35.73±11.11 years. All patients underwent total thyroidectomy. Malignancy was diagnosed in 27 out of 40 patients (67.5%). The mean nodule size was 3.67±1.69mm in malignant lesions, 40.7% of the malignant nodules were more than 3cm in size, 51.9% of malignant cases were irregular border and 29.6% of malignant lesions were hard in consistency; these data are statistically significant (<0.05) and correlated with malignancy. The rate of malignancy in cytologically indeterminate lesions was high in the present study sample compared to other reported studies. Thus, considering the fact that demographical, clinical and sonographic features were found to be inaccurate predictors of malignancy, it is our opinion that total thyroidectomy should always be recommend in such patients.

Spinal anaesthesia with local anaesthetics has limited duration. Different additives have been used to prolong spinal anaesthesia. The aim of this study was to determine the efficacy of adding dexamethasone to bupivacaine in spinal anaesthesia specially whether it would prolong the duration of sensory block/ surgical analgesia and post-operative analgesia/pain free period or not. This randomized, prospective, double-blind, clinical study was conducted in the Department of Anaesthesia, Analgesia and Critical Care of Combined Military Hospital, Chittagong from October 2016 to August 2017. Seventy two (72) adult patients scheduled for lower abdominal urological and lower limb orthopedic surgery under spinal anaesthesia were included. They were divided in two groups; each group comprised 36 patients to receive 20mg 0.5% hyperbaric bupivacaine (Bupivacaine group) or 15mg 0.5% hyperbaric bupivacaine plus 5mg dexamethasone (Bupivacaine-Dexamethasone/case group) intrathecally. The patients were evaluated for quality, quantity and duration of sensory block/surgical analgesia, post-operative analgesia/pain free period, blood pressure, heart rate, nausea, and vomiting or other complications. There were no significant differences in demographic data, sensory level and onset time of the sensory block between two groups. Duration of sensory block/Surgical analgesia in the bupivacaine group was 92.32±8.34 minutes and in the bupivacaine- dexamethasone/case group was 122.11±10.59 minutes which was statistically highly significant (p<0.001). The duration of post-operative analgesia/pain free period was 208.78±41.57 minutes in the bupivacaine group; whereas it was 412.82±71.51 minutes in the bupivacaine-dexamethasone/case group which was also statistically highly significant (p<0.001). The frequency of complications was not different between two groups. This study has shown that the addition of dexamethasone to bupivacaine in spinal anaesthesia significantly improved the duration of sensory block/surgical analgesia as well as post-operative analgesia/pain free period without any complications.

A novel strategy for the synthesis of highly stable gold nanoparticles (GNPs) was designed by reducing HAuCl4 with NaBH4 in an aqueous solution of water-soluble ionic cellulose composed of dimethylimidazolium cations and phosphite-bound cellulose anions. NMR and UV-Vis analysis along with the measurement of the zeta potential suggest that the exceptionally high stability of GNPs originates from the strong interaction of GNPs with the phosphite groups of the ionic cellulose. The thus prepared GNPs exhibit excellent catalytic activity for the reduction of 4-nitrophenol to 4-aminophenol, a model hydrogenation reaction.
RESUMEN
Hepatitis C virus (HCV) is a leading cause of chronic liver disease worldwide also in Bangladesh. Prevalence of Hepatitis C virus infection in rural adult population of Bangladesh is reported to be 0.6% but the exact pattern of existing genotype has not been well studied. Genotyping of HCV is important for the planning of treatment duration and predicting the response to treatment in HCV infection. This study was done to identify the existing HCV genotypes in the diagnosed cases of chronic hepatitis C infection in Bangladesh. This study was a prospective as well as retrospective cross-sectional observational study done in the department of Gastroenterology of Bangabandhu Sheikh Mujib Medical University, Dhaka Bangladesh. Cases were also taken from department of Hepatology of Bangabandhu Sheikh Mujib Medical University and Square General Hospital, Dhaka. The study was from January 2010 to March 2011. In total, 417 patients having chronic HCV confirmed by positive anti-HCV and HCV-RNA tests attending to above mentioned institutions were included in this study. Out of the 417 study subjects, 303 were males (72.66%) and 114 (27.34%) were females between 05 to 78 years of age. Most cases were in the age group 30-50 years (57.06%). The study showed that 209 (50.19%) were infected with Genotype 3. Next common identified genotype of HCV was a combination of type 3 & 4, which accounted for 120 (28.77%) and genotype -1 represented 59 (14.14%) of the cases. Other less common identified genotypes were 2, 4, 5 and mixed genotypes -1 & 3, 5 & 6 and 2 & 3; the figure being 12(2.87%), 8(1.91%), 1(0.23%), 5(1.19%), 2(0.47%) and 1(0.23%) respectively. Several subtypes were also found. Genotype 3 was the commonest HCV genotype among the Bangladeshi population. Different HCV genotypes will give a good idea regarding the plan of treatment and possible response rate as well as prognosis of HCV infection in Bangladesh. This study had some limitation like relatively smaller sample size and shorter period for the study. Further studies over a larger population are needed to draw any conclusive opinion.

In this ongoing prospective study conducted in University Cardiac Center, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from July 2004 to January 2006. Fifty (50) patients (mean age 56+/-7.2 years) underwent stentangioplasty were evaluated. The study group of 50 patients consisted of 42 (84%) men and 08 (16%) women. The aim of this study was to evaluate in-hospital success, failure and complications during the procedures. About risk factors 19(38%) had hypertension, 13(26%) were smoker, 11(22%) suffered from diabetes mellitus, 05(10%) had family history of ischaemic heart disease. Average left ventricular ejection fraction was 54+/-7. Target vessel percutaneous coronary angioplasty (PTCA) were done in 61 vessel, intracoronary stent implanted in 58 vessels, direct stenting were done in 35 cases, failed PTCA were in 03(6%) cases and two had dissection. The native vessels had a mean reference diameter of 2.91 mm and their luminal diameter increased significantly after percutaneous coronary intervention (PCI). All the patients were discharged by one to three days of the procedure with improvement of their clinical condition. In conclusion, intracoronary stent deployment in coronary artery stenosis following balloon angioplasty is a valid and beneficial strategy with good in-hospital results.

Bone mineral densitometry was done in 217 women in their menopausal period using Dual energy X-ray absorptiometry (DEXA) method. All the patients were presented with different post menopausal syndromes. Quantification of bone mineral density were done in proximal femur and lumber spines of all the patients along with plain X-ray of the sites. One hundred and thirty nine patients showed normal bone mineral density in our study. Rest 78 patients showed declination of bone mineral density from mild osteopenia to severe osteoporosis. We conclude that Dual energy X-ray absorptiometry bone mineral measurement is an unique, non-invasive method in detecting bone mass disorder in post-menopausal women with low back pain and should be the first choice of investigation, for the earliest detection of bone loss and thus fracture risk can be reduced by appropriate management.

Antibodies to the degenerate repeats of EB200, a part of the Plasmodium falciparum antigen Pf332, are protective in monkeys. To analyse the prevalence, magnitude and specificity of antibodies to EB200 in malaria-exposed humans, the IgG antibody reactivity with recombinant EB200 protein as well as with crude malaria antigen was determined in Senegalese donors (n = 100; 4-87 years). Antibody reactivity with EB200 was low or absent in children below 15 years but was prevalent and significantly higher in older donors. In comparison, all individuals displayed reactivity with a crude malaria antigen preparation, which also increased with age. The reactivity with the crude malaria antigen was correlated to the reactivity with EB200, suggesting that the low levels of IgG to EB200 found in some adult donors reflected a limited degree of recent exposure to parasites rather than a selective non-responsiveness to Pf332. Comparison of serological and clinical data showed that high levels of antibodies to crude malaria antigen and to EB200 were predictive of fewer future clinical attacks of malaria. A reactivity pattern very similar to that found in Senegalese donors was observed in Liberian adults where 80% of the sera showed reactivity with EB200 and all peptides were recognized by between 60 and 100% of the donors. This strong reactivity with EB200-derived overlapping peptides suggests that the epitopes in EB200, to a large extent, are linear. In the light of previous data on the parasite neutralizing capacity of antibodies to Pf332, the present results emphasize the potential interest of Pf332-derived sequences for inclusion in a subunit vaccine against P. falciparum malaria.
