Abstract
Control of pain in patients with chronic pancreatitis is difficult because 30.0% to 50.0% of patients still experience persistence or recurrence of pain even after surgery. So a combined approach of surgery and coeliac plexus neurolysis was carried out in this study to see the relief of pain and reduce the requirement of analgesics in these patients. This prospective observational comparative study was carried out in the Department of Hepatobiliary, Pancreatic and Liver Transplant Surgery in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from November 2017 to October 2018. Forty one (41) study participants with the diagnosis of chronic pancreatitis were included consecutively in this study. The participants were divided into two groups. Group I (n=18) underwent pancreatic surgery with coeliac plexus neurolysis by infiltration of 20ml of 100% alcohol in the loose areolar tissue 10ml each into right and left para-aortic space at the level of coeliac trunk and Group II (n=23) underwent pancreatic surgery only. Participants' preoperative data were collected from patient record file. Number, frequency and intensity of pain and requirement of amount of analgesics for the last 3 months were recorded from patients' history. The intensity of pain was categorized by visual analog scale (VAS) preoperatively. The participants of both groups were followed up at 1, 2 and 3 months interval and asked for disappearance or reduction of pain, frequency of attack and requirement of analgesics. Again visual analog scale was used for categorization of pain. Pain free period was recorded after the end of follow up period. Pain reduction occurred after surgery in both groups. But when pain relief was compared on the basis of VAS (Visual Analogue Scale), it was significantly better in Group I after 1 month of surgery than Group II (p=0.05). But 2 and 3 months after surgery this difference became insignificant (p=0.246 and 0.264). No statistical difference was found in terms of analgesic usage, severe acute attack or hospital admission (p=0.511, 0.439 and 0.495) at the end of 3 months follow up. Participants in Group I had significantly longer pain free period than Group II (p=0.025). Regarding complications, postural hypotension developed in 5.6% (1) patients. Diarrhea developed in 11.1% (2) patients in Group I and wound infection developed in 2 patients in each groups respectively. No patients developed any major complications like anastomotic leakage, deep or organ or space infection. Intraoperative coeliac plexus neurolysis reduces pain immediately after surgery and provides longer pain free period in patients with chronic pancreatitis after surgery.

Abstract
OBJECTIVES COVID-19 (SARS-CoV-2) pandemic has infected hundreds of millions and inflicted millions of deaths around the globe. Fortunately, the introduction of COVID-19 vaccines provided a glimmer of hope and a pathway to recovery. However, owing to misinformation being spread on social media and other platforms, there has been a rise in vaccine hesitancy which can lead to a negative impact on vaccine uptake in the population. The goal of this research is to introduce a novel machine learning-based COVID-19 vaccine misinformation detection framework. STUDY DESIGN We collected and annotated COVID-19 vaccine tweets and trained machine learning algorithms to classify vaccine misinformation. METHODS More than 15,000 tweets were annotated as misinformation or general vaccine tweets using reliable sources and validated by medical experts. The classification models explored were XGBoost, LSTM, and BERT transformer model. RESULTS The best classification performance was obtained using BERT, resulting in 0.98 F1-score on the test set. The precision and recall scores were 0.97 and 0.98, respectively. CONCLUSION Machine learning-based models are effective in detecting misinformation regarding COVID-19 vaccines on social media platforms.

Abstract
Gut microbes play a crucial role in the maintenance of human health. Components in the diet of the host affect their metabolism and diversity. Here, we investigated the influences of three commonly used non-caloric artificial sweeteners-aspartame, acesulfame K and sucralose-on the growth and metabolism of an omnipresent gut microbe Escherichia coli K-12. Methods: Growth of E. coli in the presence of aspartame, acesulfame K and sucralose in media was assessed and the influences of these artificial sweeteners on metabolism were investigated by relative expression analysis of genes encoding the rate limiting steps of important metabolic pathways as well as their global metabolomic profiles. Results: As a whole, E. coli growth was inhibited by aspartame and induced by acesulfame potassium, while the effect of sucralose on growth was less prominent. Although the expressions of multiple key enzymes that regulate important metabolic pathways were significantly altered by all three sweeteners, acesulfame K caused the most notable changes in this regard. In multivariate analysis with the metabolite profiles, the sucralose-treated cells clustered the closest to the untreated cells, while the acesulfame potassium treated cells were the most distant. These sweeteners affect multiple metabolic pathways in E. coli, which include propanoate, phosphonate, phosphinate and fatty acid metabolism, pentose phosphate pathway, and biosynthesis of several amino acids including lysine and the aromatic amino acids. Similar to the gene expression pattern, acesulfame potassium treated E. coli showed the largest deviation in their metabolite profiles compared to the untreated cells.

Abstract
Insulinoma is a rare variety of endocrine neoplasm and is usually benign, solitary, and small in size. The hallmark of this disorder is high endogenous insulin secretion resulting in development of symptoms of hypoglycemia. Insulinomas account for 60% of islet cell tumors (ICT) of the pancreas. Ninety percent (90%) of the insulinomas measure less than 2cm. Early localization of the disease is essential to prevent lethal hypoglycemia. Here we report a case of insulinoma in a 28 year old female who subsequently underwent distal pancreatectomy with splenectomy on February 2017 in Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh.

Abstract
The human gut is inhabited by several hundred different bacterial species. These bacteria are closely associated with our health and well-being. The composition of these diverse commensals is influenced by our dietary intakes. Non-caloric artificial sweeteners (NAS) have gained global popularity, particularly among diabetic patients, due to their perceived health benefits, such as reduction of body weight and maintenance of blood glucose level compared to caloric sugars. Recent studies have reported that these artificial sweeteners can alter the composition of gut microbiota and, thus, affect our normal physiological state. Here, we investigated the effect of aspartame and acesulfame potassium (ace-K), two popular NAS, in a commercial formulation on the growth and metabolic pathways of omnipresent gut commensal Escherichia coliby analyzing the relative expression levels of the key genes, which control over twenty important metabolic pathways. Treatment with NAS preparation (aspartame and ace-K) modulates the growth of E. colias well as inducing the expression of important metabolic genes associated with glucose (pfkA, sucA, aceE, pfkB, lpdA), nucleotide (tmk, adk, tdk, thyA), and fatty acid (fabI) metabolisms, among others. Several of the affected geneswere previously reported to be important for the colonization of the microbes in the gut. These findings may shed light on the mechanism of alteration of gut microbes and their metabolism by NAS.

Abstract
Hydatid disease is one of the diseases that have been discovered in the ancient times. Liver and lung are the most commonly affected organs, though it can involve any organs. Hydatid disease involving both the liver and the lung is reported about 10% of the cases. Here we report a case of 34 year old male presented with upper abdominal pain and intermittent fever for 3 months admitted in October 2016. His chest radiograph and computed tomography scan revealed large cystic lesion at right lung and another similar large lesion in the right lobe of liver. Echinococcus antibody was found positive. We treated him surgically. Histopathology reports confirmed concomitant hydatid cyst of both the lung and the liver.

Abstract
Recurrent cholangitis and sepsis are common complications after surgical treatment for hepatolithiasis as total clearance is not always possible. This retrospective study is designed to see the effect of our treatment for hepatolithiasis on stone clearance and post operative complications. We have treated 60 patients with hepatolithiasis surgically from September 2010 to September 2016 in the Department of Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Various operative procedures were applied on the basis of location of stone and status of biliary tree. Choledocoscopic examination was performed during surgery for checking and cleaning of intrahepatic duct. Regular follow up was given and outcome was assessed. The chronological changes of treatment methods for patients with hepatolithiasis were analyzed for appropriate treatments for particular type. There were 22 males and 38 females with age ranges from 15 to 60 years. The stone were located in left duct (56.6%), right duct (10%) and both duct (33.4%). The most commonly performed operation was extended choledocholithotomy and hepatolithotomy and it was performed in 28 patients (46.7%). Segmentectomy and lobectomy was performed in 17 patients (28.3%). Common bile duct (CBD) excision, hepatolithotomy and hepaticojejunostomy with or without segmentectomy, lobectomy and Houston access loop formation was performed in rest of the patients. Stones could be removed completely in all patients who underwent lobectomy or segmentectomy. In contrast stone clearance was possible only in 57.2% and 55.5% who underwent extended choledocholithotomy and hepatolithotomy, and excision of CBD, hepatolithiasis with hepaticojejunostomy for unilateral or bilateral hepatolithiasis respectively. Houston's access loop to stomach was made in 2 patients for future endoscopic removal of stone. There was no mortality in the present series but morbidity occurred in 18 patients; wound infection (n=15, 25%), bile leakage (n=1, 1.7%), and renal dysfunction (n=1, 1.7%), septicemia (n=1, 1.7%). Patients who underwent lobectomy or segmentectomy did not develop cholangitis or sepsis on 1 to 3 years follow up. In contrast who underwent extended choledocholithotomy and hepatolithotomy, 70.8% patients developed cholangitis and sepsis, and the patients who underwent excision of CBD, hepatolithotomy with hepaticojejunostomy 50% developed cholangitis and sepsis within 1 to 3 years of follow up, required re-operations or conservative treatment. The difference of developing postoperative cholangitis and sepsis is significant (p<0.05) between patient who underwent extended choledocolithotomy and hepatolithotomy, and who underwent excision of CBD, hepatolithotomy and Roux-en-Y hepaticojejunostomy. In conclusion, lobectomy or segmentectomy is the best option for hepatolithiasis if the stones are limited to a lobe or segment. Excision of CBD, hepatolithotomy with hepaticojejunostomy is better than extended choledocholithotomy and hepatolithotomy for bilateral hepatolithiasis. Huston's access loop formation associated with other procedures may be considered for bilateral hepatolithiasis for future minimal invasive stone retrieval procedure as residual stones and recurrent stone formation is common.
