Abstract
Now-a-days Laparoscopic cholecystectomy is regarded as the gold standard treatment for benign gallbladder disease but in certain situations conversion to open cholecystectomy is extremely important for the safety of the patient. The objective of this study was to evaluate the reason for conversion of this operation to open surgery. This prospective study was carried out on 392 patients in a single unit of Department of Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh and in a private hospital from July 2013 to December 2018. Maximum (28.3%) patients were 31-40 years age group. Majority (75.3%) was female and 24.7% were male. It was observed that only 2.1% were converted due to dense adhesion (n=3), severe inflammation (n=2), difficult to define anatomy of Calot's triangle (n=2) and Mirizzi syndrome (n=1). Meticulous dissection and proper case selection can reduce the rate of conversion to open surgery.

Abstract
Background Pancreatic adenocarcinoma (PAC) is a deadly disease with an overall 5-year survival of less than 8%. The current literature on patient outcomes are limited by small samples sizes and patients enrolled in clinical trials. There are no prognostic tools for patients with pancreatic cancer. Purpose To develop a prognostic survival model for patients with pancreatic cancer Method All patients with a diagnosis of pancreatic cancer cancer from January 2007 to December 2020 were identified through the Ontario Cancer Registry. The primary outcome was survival. The cohort was used to develop a multivariable cox proportional hazards regression model with baseline characteristics under a backward stepwise variable selection process to predict the risk of mortality. Covariates included patient age, sex, tumour location, cancer stage, treatment types, distance to a cancer centre, hospitalizations, comorbidities, access to family physician, and symptoms as captured using the Edmonton Symptom Assessment System datasets. Result(s) There was a total of 17,450 pancreatic cancer patients in the cohort, 48% of which were female and the mean age was 72 years. 44% of patients presented with a tumor in the head of the pancreas. Among those with stage data (44%), 24% were stage IV at diagnosis. Mean survival was approximately 0.7 years. Approximately 60% were hospitalized in the 3 months prior to diagnosis. Almost all patients had a family doctor rostered (95%). In multivariate analysis, key predictors of survival assessed at the time of diagnosis were age, sex, tumour location in the pancreas, stage at diagnosis, pain, appetite functional status and treatment choice (all p<0.001). Using these variables, we created a prediction model that can estimate one-year probability of death with high discrimination (area under the curve = 0.82, c-statistic 0.76). Conclusion(s) Our model accurately predicts one-year pancreatic cancer survival risk using clinical symptom and performance status data. The model has the potential to be a useful prognostic tool that can be completed by patients and their caregivers in support of patient-centered care.

Abstract
Phosphorus (P) is a vital macronutrient required for soybean growth and development but is a finite resource in agriculture worldwide. Low inorganic P availability in soil is often a significant constraint for soybean production. However, little is known about the response of P supply on agronomic, root morphology, and physiological mechanisms of contrasting soybean genotypes at various growth stages and the possible effects of different P on soybean yield and yield components. Therefore, we conducted two concurrent experiments using the soil-filled pots with six genotypes (deep-root system: PI 647960, PI 398595, PI 561271, PI 654356; and shallow-root system: PI 595362, PI 597387) and two P levels [0 (P0) and 60 (P60) mg P kg-1 dry soil] and deep PVC columns with two genotypes (PI 561271 and PI 595362) and three P levels [0 (P0), 60 (P60), and 120 (P120) mg P kg-1 dry soil] in a temperature-controlled glasshouse. The genotype × P level interaction showed that increased higher P supply increased leaf area, shoot and root dry weights, total root length, shoot, root, and seed P concentrations and contents, P use efficiency (PUE), root exudation, and seed yield at different growth stages in both experiments. At the vegetative stage (Experiment 1), shallow-rooted genotypes with shorter life cycles had more root dry weight (39%) and total root length (38%) than deep-rooted genotypes with longer life cycles under different P levels. Genotype PI 654356 produced significantly higher (22% more) total carboxylates than PI 647960 and PI 597387 under P60 but not at P0. Total carboxylates positively correlated with root dry weight, total root length, shoot and root P contents, and physiological PUE. The deep-rooted genotypes (PI 398595, PI 647960, PI 654356, and PI 561271) had the highest PUE and root P contents. In Experiment 2, at the flowering stage, genotype PI 561271 had the greatest leaf area (202%), shoot dry weight (113%), root dry weight (143%), and root length (83%) relative to the short-duration, shallow-rooted genotype PI 595362 with external P applied (P60 and P120), with similar trends at maturity. PI 595362 had a greater proportion of carboxylates as malonate (248%), malate (58%), and total carboxylates (82%) than PI 561271 under P60 and P120 but no differences at P0. At maturity, the deep-rooted genotype PI 561271 had greater shoot, root, and seed P contents and PUE than the shallow-rooted genotype PI 595362 under increased P rates but no differences at P0. Further, the genotype PI 561271 had higher shoot (53%), root (165%), and seed yield (47%) than PI 595362 with P60 and P120 than P0. Therefore, inorganic P application enhances plant resistance to the soil P pool and maintains high soybean biomass production and seed yield.

Abstract
Aspergillosis is mainly a lung infection in human. This is caused by the fungus Aspergillus. Though, most of the strains are harmless to humans, only a few of them can cause serious diseases mostly in immunocompromised individuals. The individuals with a medical history of respiratory problems are at high risk of infection. An aspergillosis patient if not treated well within time it may result in invasive aspergillosis developing lung fibrosis, huge hemoptysis and multiple organ failures, CNS and brain infections, endocarditis and death. The present paper deals with their disease causing abilities, diagnosis and treatment in human in the light of recent researches done so far in the field of medical microbiology and pathology.

Abstract
This study explores the antioxidant activity, phytochemical screening, total phenolic and flavonoids contents in the extracts of four locally available weeds plants namely Convolvulus arvensis, Chenopodium murale, Avena fatua and Phalaris minor with different solvents. The antioxidant activities of these extracts were determined via various in-vitro methods such as total antioxidant activity (TAA), reducing power (RP), DPPH (2,2-Diphenyl-1-Picrylhydrazyl) free radical scavenging and hydrogen peroxide scavenging assays. Phytochemical screening was performed both qualitatively as well as quantitatively. Total phenolic content (TPC) and total flavonoid content (TFC) were determined through Folin- Ciocalteu reagent and aluminium chloride methods respectively. Methanol-chloroform solvent showed the presence of a high amount of TPC in milligram of gallic acid equivalent per gram of dry weight (mg of GAE/g of DW) in the extracts of all weeds. Their descending sequence was Avena fatua (74.09) ˃ Phalaris minor (65.66) ˃ Chenopodium murale (64.04) ˃ Convolvulus arvensis (61.905), while, chloroform solvent found to be best solvent for the extraction of TFC. Methanol-chloroform solvent was also found to be best solvent for TAA (Total antioxidant activity assay) which showed values in milligram of ascorbic acid equivalent per gram of dry weight (mg of AAE /g of DW), for DPPH scavenging activity, reducing power (antioxidant activity) and hydrogen peroxide scavenging activity. Phytochemical screening indicated the presence of polyphenols, flavonoids, tannins, saponins, alkaloids and glycosides in these weeds.

Abstract
Abstract
Background
Patients with pancreatic cancer face challenging decisions regarding treatment choices following their diagnosis and often lack data on end-of-life (EOL) outcomes. Without the available information, older patients may be undertreated, dying earlier than they would have with treatment, while others may be overtreated and exposed to aggressive measures with harmful side effects.
Aims
To describe survival and EOL outcomes among pancreatic cancer patients based on index cancer treatment, disease stage, and patient characteristics.
Methods
We conducted a population based cohort study in Ontario, Canada of patients who died from April 2010 to December 2017 and were diagnosed with pancreatic cancer prior to death. We used administrative databases to collect data on demographics, baseline health status, treatments, and outcomes. The primary exposure was index cancer treatment (no treatment, radiation, chemotherapy alone, surgery alone, and surgery with chemotherapy). The primary outcomes were mortality, health care encounters per 30 days in the last six months of life, and palliative care visits per 30 days within the last six months of life. Secondary outcomes were location of death (institution vs. community), hospitalization within the last 30 days of life, and receipt of chemotherapy within the last 30 days of life. We estimated the association between the exposure and outcomes using multivariable models, adjusting for demographics, comorbidities, and cancer stage. Hazard ratios, adjusted mean differences, and odds ratios were reported with 95% confidence intervals.
Results
Our cohort included 9950 adults with a median age at diagnosis of 78. 56% received no index treatment, 5% underwent radiation, 27% underwent chemotherapy alone, 7% underwent surgery alone, and 6% underwent surgery and chemotherapy. In the multivariable regression (Table and Figure), radiation, chemotherapy alone, surgery alone, and surgery with chemotherapy were all associated with decreased mortality and fewer healthcare encounters. All groups except radiation were associated with fewer palliative care visits. All treatment groups were associated with lower odds of institutional death and hospitalization within the last 30 days of life, and higher odds of chemotherapy within the last 30 days of life.
Conclusions
Our data, the first to provide EOL outcome estimates based on index cancer treatment, can help patients make initial treatment decisions after a diagnosis of pancreatic cancer.

Abstract
Background The Calgary Bile Leak Rule was developed to identify patients in whom biliary stent removal via gastroscopy could be safely performed in lieu of ERCP for post-surgical bile leaks. Aims This study aimed to evaluate a Modified Calgary Bile Leak Rule (MCBLR) for a cohort of patients who underwent laparoscopic cholecystectomy complicated by bile leak. Methods This retrospective cohort study included patients who underwent ERCP for management of laparoscopic cholecystectomy-induced bile leaks between 2005 and 2017. The primary outcome was defined as the absence of persisting bile leak or other pathology on follow-up ERCP. The MCBLR includes a) normal post-surgical serum alkaline phosphatase, b) small or absent leak with no other biliary pathology on initial ERCP, and c) time between initial and follow-up ERCP was 4–8 weeks. Test performance of the prediction rule was analyzed by calculating sensitivity, specificity, positive predictive value and negative predictive value. Results 124 cases met inclusion criteria, of which 116 (94%) of bile leak cases had no leak identified during the follow-up ERCP. 8 (6.4%) had a persisting bile leak on follow-up ERCP. Bivariate analysis found no factors significantly associated with the primary outcome. The MCBLR demonstrated a sensitivity of 100% (95% CI 63% - 100%), a specificity of 35% (95% CI 26% - 44%), a positive predictive value of 10% (95% CI 4% - 18%), and a negative predictive value of 100.0% (91% to 100%). Conclusions The MCBLR demonstrated high sensitivity and negative predictive value for determining the need for repeat ERCP following endoscopic management of laparoscopic cholecystectomy-induced bile leaks.

Abstract
Background Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference –1·69 [–9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5–8] vs 6 [5–8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52–23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75–0·86]; p<0·0001). Interpretation Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status. Funding No funding.

Abstract
AbstractEnantiomerically pure 9-substituted 11-oxa[9]helicene derivatives have been synthesized through furan-ring formation by a nucleophilic cyclodehydration reaction of enantiomerically pure helical polycondensed 2,2′-diphenoquinone derivatives (1,1′-bibenzo[c]phenanthrenylidene-2,2′-diones). (P)-2,2′-diphenoquinone derivatives afforded (P)-oxa[9]helicenes, whereas (M)-2,2′-diphenoquinone derivatives afforded the corresponding (M)-oxa[9]helicenes. Therefore, the ring-closing reaction afforded the corresponding enantiomerically pure products without decreasing the enantiomeric excess, and it proceeded stereospecifically with retention of the configuration. The thermal stability of an oxa[9]helicene was studied by determining the decrease in its enantiomeric excess at various temperatures, and its racemization barrier was found to be 165.6 kJ/mol.

Abstract
This is perhaps one of the wonders of science that currently we have certain effective anthelmintics to cure more than 300 types of parasitic worm infections found in the human body. Therefore, we have never paid the due attention in some lethal consequences caused by them. The present paper is first in the series of human helminthic parasitology and an attempt to discuss certain roundworms causing various ailments and diseases in human in the light of recent researches done so far in the same field.

Abstract
Abstract
Background
Breast cancer diagnosed at younger age has aggressive biology being triple negative and high grade and associated with poor prognosis.
Method
Retrospectively data of 121 patients age 30 years or younger registered during the year 2008 was reviewed. Demographics studied were age at diagnosis, gender, pregnancy, or lactation associated, family history, histopathological diagnosis, stage of the disease, receptors, type of treatment, response, local recurrence, distant relapse, survival.
Results
One patient was male. Age range 20 -30 years, single patient had bilateral involvement. half 50.4%(n = 61) patients had locally advanced disease at presentation. Pregnancy/ lactation associated breast cancer was seen in 29.8%(n = 36). Most common stage was stage III (52.1%) & stage II (33.9%). IDC was the most common histology 94.2% (n = 114) Triple negative was most common molecular subtype present in 46.3%(56). After 5 years follow up, local recurrence was observed in 12.4%(n = 15), cancer related deaths were 42.1%(n = 51).
Conclusions
Breast cancer in very young has very aggressive tumor biology, needs aggressive treatment with surgery, chemotherapy, radiation therapy and hormonal therapy, furthermore there is need to identify possible environmental factors which may contribute in the rising incidence in this age group.

Abstract
Malakand region is an endemic area for cutaneous leishmaniasis (CL). However, there are limited number of studies of this disease in Pakistan. Therefore, a study was conducted to understand the level of awareness attitude and practice among the residents of Makaland towards CL and the disease vectors. This study adopted a cross-sectional approach with a total of 400 respondents (n=93 rural and n= 307 urban). Overall, the population in Malakand region (61.2%) were well-informed in the role of sand fly in transmitting diseases, but most lack knowledge on the vector's behavior and almost a quarter (24.5%) were unable to provide knowledge on proper control measures. Alarmingly, the practice and attitudes of the general population was not satisfactory as close to half (49.8%) of the population did adopt any control method. This study calls for increase in awareness through health education campaign to reduce the risk of cutaneous leishmaniasis outbreaks in the future.

Abstract
Distribution pattern and relative abundance of the agricultural rodent pests of rain-fed and irrigated areas of district Swat Khyber Pakhtunkhwa, Pakistan were recorded from April 2011 to November 2013 using wire mesh live traps. A total of 350 rodents (269 Rattus rattus and 81 Mus musculus) were captured under 2268 trap nights (trap success: 0.15). Regression of daily captures on cumulative captures revealed an estimate of 350 rodents from all the sampled structures with an average of 21.8 rodents per crop field. House rats (R. rattus; 76.8% of captures) were numerically dominant in almost all types of agricultural fields, and were significantly different from the mice (Mus musculus; 23.1% of captures). Both species were found together in some fields. The sex ratio revealed that males outnumbered the females in both of the reported species.

Abstract
Abstract
Background
Pancreatic cystic lesions are increasingly identified in persons undergoing abdominal imaging. Serous cystic neoplasms (SCNs) have a very low risk of malignant transformation. Resection of SCNs is not recommended in the absence of related symptoms. The accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) to identify SCNs is not known and may impact clinical care.
Aims
To evaluate the accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) for the diagnosis of SCN. To see how this can impact the decision to resect suspected SCNs.
Methods
Retrospective cohort study of patients from the University Health Network with suspected SCNs from 2017–2020 who underwent either a CT or MRI of the abdomen. Reports noting pancreatic cystic lesions were identified and reviewed. Only cases with suspected SCNs were included. Clinical (age, sex, symptoms, treatment) and radiographic (type of imaging, reported cyst characteristics) data was collected. Pathology was reviewed for all cases where the cysts was biopsied or resected during follow-up. The gold standard for the diagnosis for SCN was pathology of resected specimen or EUS-guided biopsy cytopathology showing no evidence of a mucinous lesion, CEA level below 10ug per L and amylase level below 50 U/L.
Results
163 patients were included in the study. 99 (61%) were female and 98 (60%) underwent CT scan. EUS-guided biopsy was performed in 24 (15%) of patients and 8 (5%) had surgical resection. Multidisciplinary review was performed in 6 of the 8 cases that went to surgery. Of the resected specimens, 5 (63%) were SCN, 1 was a mucinous cystic lesion, 1 was a neuroendocrine tumor and 1 was a carcinoma. Two patients underwent EUS evaluation prior to surgical resection. In one case SCN was resected when EUS reported an undetermined cyst type. Reasons for surgical resection were: the diagnosis of serous cyst was not definitive (n=5), symptoms (n=2), and high-risk mucinous cystic neoplasm identified on EUS (n=1). Of 30 patients with pathology available, 15 (50%) were confirmed to have a SCN. CT and MRI had a sensitivity, specificity, positive predictive value and negative predictive value of 93%, 25%, 52% and 80%, respectively.
Conclusions
Surgical resection for SCN lesions is driven by diagnostic uncertainty after cross-sectional imaging. Multidisciplinary review and EUS evaluation may improve diagnostic accuracy and should be considered prior to surgical resection of possible SCN lesions.

Abstract
Background:
Diabetes mellitus is the most occurring non-communicable disease resulting
in a high blood glucose level. There has been an immense interest in the development of alternative
medicines for diabetes treatment, specifically screening functional foods for phytochemicals
with the capability of delaying or preventing glucose absorption through digestive enzymes (e.g.
α-amylase) inhibition. So, the development of α-amylase inhibitors derived from natural food products
is an alternative way to prevent diabetes mellitus.
Objective:
In this study, organic solvent extracts of the Arachis hypogaea (Peanut) and Cinnamomum
tamala (Indian bay leaf/Tejpata) were used to investigate their potential α-amylase inhibition
and cytotoxic activities through α-amylase inhibition assay and brine shrimp lethality bioassay respectively.
Methods:
The α-amylase inhibition assay was performed using the 3,5-dinitrosalicylic acid method
for different concentrations of plant extracts. The optical density (OD) of the solutions were measured
to determine the inhibition activity at 540 nm using a spectrophotometer. The cytotoxicity of
the plant extracts was measured using brine shrimp (Artemia salina) lethality bioassay.
Results:
Among the different organic solvent extracts, peanut seed ethanol extract showed the highest
α-amylase inhibition activity (67.68±8.67%) at 1.25 μg/mL concentration with an IC50 value of
0.61 μg/mL which is very close to standard α-amylase inhibitor Acarbose (72.34±4.23%) with an
IC50 value of 0.32 μg/mL while acetone extract of Indian bay leaf exhibited the lowest inhibition
activity (47.75±1.63%) with an IC50 value of 1.42 μg/mL at the same concentration. Besides, the
maximum cytotoxic activity was found in acetone extract of peanut shell with an LC50 value of
57.87 μg/mL, whereas ethanol extract of peanut seed showed the lowest cytotoxicity with an LC50
value of 413.90 μg/mL.
Conclusion:
The result of the present work clearly indicates the potentiality of peanut seed ethanol
extract to be used in the management of hyperglycemia as it significantly inhibits α-amylase activity
while showing less cytotoxic activities.

Abstract
BACKGROUND The primary aim of the study is to evaluate the functional outcome following AMIC procedure in patients with osteochondral injury of the talus. The secondary aim is to evaluate if size of the lesion and patient's age influence outcome. MATERIALS AND METHODS This is a retrospective study of 25 patients who underwent AMIC procedure of the talus treated by a single surgeon. Functional outcomes were evaluated using pre and post operative AOFAS and VAS scores. RESULTS The mean lesion size was 1.74 cms with 88% of lesions in the study more than 1.4 cms. There was a significant improvement in AOFAS score with mean improvement of 49.40 (p < 0.05) and VAS score of 5.36 (p < 0.05). We could not find any correlation between either age or lesion size with functional outcome for AMIC procedure. CONCLUSION AMIC procedure seems to be a reliable treatment method for larger diameter osteochondral lesions of the talus up to 2.5 cms in diameter.

Abstract
Epidemiology, ventilator management, and outcome in patients receiving invasive ventilation in intensive care units (ICUs) in middle-income countries are largely unknown. PRactice of VENTilation in Middle-income Countries is an international multicenter 4-week observational study of invasively ventilated adult patients in 54 ICUs from 10 Asian countries conducted in 2017/18. Study outcomes included major ventilator settings (including tidal volume [V T] and positive end-expiratory pressure [PEEP]); the proportion of patients at risk for acute respiratory distress syndrome (ARDS), according to the lung injury prediction score (LIPS), or with ARDS; the incidence of pulmonary complications; and ICU mortality. In 1,315 patients included, median V T was similar in patients with LIPS < 4 and patients with LIPS ≥ 4, but lower in patients with ARDS (7.90 [6.8-8.9], 8.0 [6.8-9.2], and 7.0 [5.8-8.4] mL/kg Predicted body weight; P = 0.0001). Median PEEP was similar in patients with LIPS < 4 and LIPS ≥ 4, but higher in patients with ARDS (five [5-7], five [5-8], and 10 [5-12] cmH2O; P < 0.0001). The proportions of patients with LIPS ≥ 4 or with ARDS were 68% (95% CI: 66-71) and 7% (95% CI: 6-8), respectively. Pulmonary complications increased stepwise from patients with LIPS < 4 to patients with LIPS ≥ 4 and patients with ARDS (19%, 21%, and 38% respectively; P = 0.0002), with a similar trend in ICU mortality (17%, 34%, and 45% respectively; P < 0.0001). The capacity of the LIPS to predict development of ARDS was poor (ROC AUC of 0.62, 95% CI: 0.54-0.70). In Asian middle-income countries, where two-thirds of ventilated patients are at risk for ARDS according to the LIPS and pulmonary complications are frequent, setting of V T is globally in line with current recommendations.

Abstract
Cytomegalovirus is a kind of herpes virus, HHV-5. It primarily causes congenital infections and the fetal abnormalities during pregnancies. Sometimes, very serious complications and consequences may occur. As human cytomegalovirus is a ubiquitous virus occurring worldwide in nature their infections are very common in human. It has got lifelong latency in human with their reactivation causing cancer in future. The present paper deals with the study of causes and consequences of disease complex and the development of cancer by primary infection and the reactivation of HCMV in human.

Abstract
Invertase, the key enzyme responsible for sucrose hydrolysis. Inhibition of invertase can decrease the postprandial blood sugar level in diabetic patients and keep the blood glucose level normal where cytotoxicity to fast-growing cells like those of brine shrimp (Artemia salina) nauplii is a great measurement for further important drug development. This study was aimed to investigate potential anti-diabetic and cytotoxic activities of the ethanol and acetone extracts of Swietenia macrophylla leaves, Syzygium cumini and Trigonella foenum-graecum seeds. Invertase inhibition activities of S. macrophylla leaves, S. cumini, and T. foenum-graecum seeds were measured by spectrophotometrically using standard protocols and cytotoxicity were measured by brine shrimp lethality bioassay. Among the plant extracts, all ethanol extracts showed higher invertase inhibition activities than all acetone extracts. S. cumini seed ethanol extract showed the highest invertase inhibition activity whereas S. macrophylla leaves acetone extract showed the lowest invertase inhibition activity. The maximum toxicity was observed in ethanol extract of T. foenum-graecum seed whereas the lowest toxicity was observed in acetone extract of S. macrophylla leaves. Both ethanol and acetone extract of T. foenum-graecumseeds showed significant cytotoxic activities. This investigation suggested that S. cumini and T. foenum-graecum seeds possess potential antidiabetic activities and T. foenum-graecum seeds have potential cytotoxicity.

Abstract
Abstract
Background
Previous studies have demonstrated that many graduating trainees may not have all of the skills needed to independently practice endoscopic retrograde cholangiopancreatography (ERCP) safely and effectively. As a part of competency-based learning curriculum development, it is essential to provide formative feedback to trainees and ensure they acquire the knowledge and skills for independent practice.
Aims
To assess the performance of advanced endoscopy trainees across Canada using the Canadian Direct Observation of Procedural Skills (CanDOPS) ERCP assessment tool. Procedural items evaluated include both technical (cannulation, sphincterotomy, stone extraction, tissue sampling, and stent placement) and non-technical (leadership, communication and teamwork, judgment and decision making) skills.
Methods
We conducted a prospective national multi-centre prospective study. Advanced endoscopy trainees with at least two years of gastroenterology training or five years of general surgery in North America and minimal experience performing ERCPs (less than 100 ERCP procedures) were invited to participate. The CanDOPS tool was used to measure every fifth ERCP performed by trainees over a 12-month fellowship training period. ERCPs were evaluated by experienced staff endoscopists at each study site under standard clinical protocol. Cumulative sum (CUSUM) analyses were used to generate learning curves.
Results
The data from five Canadian sites and 11 trainees participated in the study. A total of 261ERCP evaluations were completed. Median number of evaluations by site and trainee was 49 (IQR 31–76) and 15 (IQR 11–45). Median number of cases trainees performed prior to their ERCP training was 50 (IQR 25–400). There was a significant improvement in almost all scores over time, including selective cannulation, sphincterotomy, biliary stenting and all non-technical skills (P<0.01). CUSUM analyses using acceptable and unacceptable failure rates of 20% and 50% demonstrated trainees achieved competency for most measures in their final month of their training. Competency in tissue sampling was not achieved within a one-year training period.
Conclusions
This is the first ERCP performance evaluation tool that examines multiple technical and non-technical aspects of the procedure. Although trainee ERCP skills do improve during their training period, there exists a notable variability in time to competency for the different skills measured using the CanDOPS tool. Large prospective research is required to determine if competency is achieved using more stringent definitions of ERCP competency and to determine factors associated with reaching competency.

Abstract
The mol-ecule of the title compound, C28H22N4O9, exhibits crystallographically imposed twofold rotational symmetry, with a dihedral angle of 66.0 (2)° between the planes of the two central benzene rings bounded to the central oxygen atom. The dihedral angle between the planes of the central benzene ring and the terminal phenol ring is 4.9 (2)°. Each half of the mol-ecule exhibits an imine E configuration. An intra-molecular O-H⋯N hydrogen bond is present. In the crystal, the mol-ecules are linked into layers parallel to the ab plane via C-H⋯O hydrogen bonds. The crystal studied was refined as a two-component pseudomerohedral twin.

Abstract
PreQ1 riboswitches regulate the synthesis of the hypermodified tRNA base queuosine by sensing the pyrrolopyrimidine metabolite preQ1. Here, we use single-molecule FRET to interrogate the structural dynamics of apo and preQ1-bound states of the preQ1-II riboswitch from Lactobacillus rhamnosus. We find that the apo-form of the riboswitch spontaneously samples multiple conformations. Magnesium ions and preQ1 stabilize conformations that sequester the ribosome-binding site of the mRNA within the pseudoknotted structure, thus inhibiting translation initiation. Our results reveal that folding of the preQ1-II riboswitch is complex and provide evidence favoring a conformational selection model of effector binding by riboswitches of this class.

Abstract
Background: Bangladesh is an agriculture-dependent country. Organophosphorus insecticides are widely used for the better outcome of cultivation. It is used for suicidal purpose due to its easy availability all over the country. Worldwide, acute pesticide poisoning is causing major health problems with high mortality in developing countries.Objective: The objective of our study was to establish that early management of acute poisoning with organophosphorus and carbamate in ICU along with ventilatory support in severe respiratory distress reduces the mortality rate.Materials and Methods: This study was conducted in the Department of Anesthesiology & ICU in Enam Medical College & Hospital, Savar, Dhaka from January 2013 to December 2015. Total 84 patients with acute poisoning cases were selected. The diagnosis was confirmed by the history of ingestion of insecticides, observing clinical signs and symptoms and presence of foul smelling of poisonous agent. Management included supportive care, intubation, artificial ventilation in selective cases, administration of antidotes as loading and maintenance dose for atropinization with atropine and pralidoxime, antibiotics, anti-ulcerant, anticonvulsant, inotropic support (in severe hypotension) along with other symptomatic treatment. After stabilization, decontamination was started with removal of contaminated clothes, thorough wash with soap and water, irrigation of eyes with water and normal saline. Gastric lavage was given within 2 to 3 hours of ingestion of poison.Results: Acute poisoning was observed more in male (60.71%) than in female (39.29%) and in age group of 21–40 years (60.71%). Suicidal attempt was present in 97.61% cases and causes of suicidal poisoning were familial disharmony (76.19%), financial loss (14.28%) and failure in examination (9.52%). Organophosphate group poison ingestion was in 77.38% cases and carbamate group poison in 21.43% and both agents in 1.19% cases. Ventilatory support was given in 48.80% cases and 78.05% patients were successfully extubated from mechanical ventilator. Mean duration of ventilatory support was 2–14 days. Out of 84 patients, 75 (89.28%) survived and 9 (10.72%) patients expired. Fifty two (61.91%) patients were discharged within 4–6 days, 16 (19.04%) within 2–3 days, and 7 (8.33%) patients were discharged within 7–14 days.Conclusion: Early ICU admission and appropriate management of patients after ingestion of poisonous agent results in reduced morbidity and mortality.J Enam Med Col 2018; 8(3): 144-152

Abstract
BACKGROUND Ethics is a part of subject philosophy and gained importance in research after the Nuremberg Code that led to Helsinki's Declaration on research ethics. In most developed countries stringent measures are taken to implement ethics in research. Awareness is on the rise in developing countries too. METHODS This cross-sectional part of mixed methods design of study is part of a PhD thesis. Data was collected from medical institutions including medical colleges, medical universities, dental colleges, and teaching hospitals of Pakistan. Questionnaires were developed, and final version was adopted after pretesting. Questionnaires were sent via registered post. RESULTS A total of 78 institutions responded. Out of 78, 48 (61.5%) were in public sector and 30(38.5%) in private sector. Seventy-four (94%) had institutional review boards. The numbers of members ranged from 1 to 15 with 40(54%) having number of members from 3 to 7. Out of 74 with IRBs, 17(23%) had members from community, 11(15%) had religious scholars and 8(11%) had members from legal background. Sixty-four (86.5%) responded that they had time frames for research proposal processing that ranged from one to 26 weeks (6.2±5.6). CONCLUSIONS It is concluded that most of the medical institutions where research is conducted and approved through deficient research ethical boards in terms of their constitution. Research ethics is not a priority area for most of the institutions. Representation of society at large is missing. National action is required at government level.

Abstract
AKT3 gene is a constituent of the serine/threonine protein kinase family and plays a crucial role in synthesis of milk fats and cholesterol by regulating activity of the sterol regulatory element binding protein (SREBP). AKT3 is highly conserved in mammals and its expression levels during the lactation periods of cattle are markedly increased. AKT3 is highly expressed in the intestine followed by mammary gland and it is also expressed in immune cells. It is involved in the TLR pathways as effectively as proinflammatory cytokines. The aims of this study were to investigate the sequences differences between buffalo and cow. Our results showed that there were substantial differences between buffalo and cow in some exons and noteworthy differences of the gene size in different regions. We also identified the important consensus sequence motifs, variation in 2000 upstream of ATG, substantial difference in the "3'UTR" region, and miRNA association in the buffalo sequences compared with the cow. In addition, genetic analyses, such as gene structure, phylogenetic tree, position of different motifs, and functional domains, were performed to establish their correlation with other species. This may indicate that a buffalo breed has potential resistance to disease, environment changes, and airborne microorganisms and some good production and reproductive traits.

Abstract
The reduction of graphene oxide (GO) has been extensively studied in literature in order to let GO partially recover the properties of graphene. Most of the techniques proposed to reduce GO are based on high temperature annealing or chemical reduction. A new procedure, based on the direct reduction of GO by etched Si substrate, was recently proposed in literature. In the present work, we accurately investigated the Si-GO interaction with x-ray photoelectron spectroscopy. In order to avoid external substrate oxidation factors we used EtOH as the GO solvent instead of water, and thermal annealing was carried out in UHV. We investigated the effect of Si(100), Si(111) and Au substrates on GO, to probe the role played by both the substrate composition and substrate orientation during the reduction process. A similar degree of GO reduction was observed for all samples but only after thermal annealing, ruling out the direct reduction effect of the substrate.

Abstract
BACKGROUND Pelareorep is an oncolytic virus with activity in many cancers including prostate. It has in vitro synergism with microtubule-targeted agents. We undertook a clinical trial evaluating pelareorep in mCRPC patients receiving docetaxel. PATIENTS AND METHODS In this randomized, open-label phase II study, patients received docetaxel 75mg/m2 on day 1 of a 21-day cycle and prednisone 5mg twice daily, in combination with pelareorep (arm A) or alone (arm B). The primary endpoint was 12 weeks lack of disease progression rate (LPD). RESULTS Eighty-five pts were randomized. Median age was 69, ECOG performance status was 0/1/2 in 31%/66%/3% of patients. Bone/regional lymph node/liver metastases were present in 98%/24%/6%. The median prognostic score was slightly higher in Arm A (144 vs. 129 p= 0.005). Adverse events were as expected but more prevalent in arm A. The 12-week LPD rate was 61% and 52.4% in arms A/B (p=0.51). Median survival was 19.1 on Arm A and 21.1 months on Arm B (HR 1.83; 95% CI 0.96 to 3.52; p=0.06). No survival benefit of pelareorep was found. CONCLUSION Pelareorep with docetaxel was tolerable with comparable LPD in both arms but response and survival were inferior and so this combination does not merit further study.

Abstract
Hymenolepiasis is a helminthic and occasionally fatal disease of human imposing heavy economic losses to human society. Present study was aimed to diagnose the school children for the prevalence and control of Hymenolepiasis. A school based cross-sectional analysis of stool samples collected from 188 children aged 06-15 years was carried out (February to June 2016). Two stool samples were collected from each student before diagnosing and after treatment. The samples were fixed in 10% formalin and observed under the light microscope using the methods of direct smear in Lugol's solution, normal saline and flotation techniques. On the basis of drugs accessibility all the H. nana infected children were divided in to 2- groups. Children in group A were treated with albendazole (bendazol) 400mg once orally, group B was treated with albendazole (zentel) 200mg orally. Eggs per gram of faeces were counted in each group before and after treatment. Of the 188 children, current study reveals only 6.08% (n=18/296) infection with H.nana and 10.5% (n=16/151) were diagnosed with co infections. The % efficacy of albendazole (Zentel) and albendazole (bendazol) against Hymenolepis nana infection was reported as 83% and 75% respectively. Present study was concluded that albendazole (zentel) is the drug of choice for the treatment of hymenolepiasis in children.

Abstract
BACKGROUND Pelareorep, a serotype 3 reovirus, has demonstrated preclinical and early clinical activity in breast cancer and synergistic cytotoxic activity with microtubule targeting agents. This multicentre, randomized, phase II trial was undertaken to evaluate the efficacy and safety of adding pelareorep to paclitaxel for patients with metastatic breast cancer (mBC). METHODS Following a safety run-in of 7 patients, 74 women with previously treated mBC were randomized either to paclitaxel 80 mg/m2 intravenously on days 1, 8, and 15 every 4 weeks plus pelareorep 3 × 1010 TCID50 intravenously on days 1, 2, 8, 9, 15, and 16 every 4 weeks (Arm A) or to paclitaxel alone (Arm B). Primary endpoint was progression-free survival (PFS). Secondary endpoints were objective response rate, overall survival (OS), circulating tumour cell counts, safety, and exploratory correlative analyses. All comparisons used a two-sided test at an alpha level of 20%. Survival analyses were adjusted for prior paclitaxel. RESULTS Final analysis was performed after a median follow-up of 29.5 months. Pelareorep was well tolerated. Patients in Arm A had more favourable baseline prognostic variables. Median adjusted PFS (Arm A vs B) was 3.78 mo vs 3.38 mo (HR 1.04, 80% CI 0.76-1.43, P = 0.87). There was no difference in response rate between arms (P = 0.87). Median OS (Arm A vs B) was 17.4 mo vs 10.4 mo (HR 0.65, 80% CI 0.46-0.91, P = 0.1). CONCLUSIONS This first, phase II, randomized study of pelareorep and paclitaxel in previously treated mBC did not show a difference in PFS (the primary endpoint) or RR. However, there was a significantly longer OS for the combination. Further exploration of this regimen in mBC may be of interest.

Abstract
BACKGROUND Recent breast cancer treatment guidelines recommend that higher-risk premenopausal patients should receive ovarian function suppression (OFS) as part of adjuvant endocrine therapy. If chemotherapy is also given, it is uncertain whether to select concurrent or sequential OFS initiation. DESIGN AND METHODS We analyzed 1872 patients enrolled in the randomized phase III TEXT and SOFT trials who received adjuvant chemotherapy for hormone receptor-positive, HER2-negative breast cancer and upon randomization to an OFS-containing adjuvant endocrine therapy, initiated gonadotropin-releasing-hormone-agonist triptorelin. Breast cancer-free interval (BCFI) was compared between patients who received OFS concurrently with chemotherapy in TEXT (n = 1242) versus sequentially post-chemotherapy in SOFT (n = 630). Because timing of trial enrollment relative to adjuvant chemotherapy differed, we implemented landmark analysis re-defining BCFI beginning 1 year after final dose of chemotherapy (median, 15.5 and 8.1 months from enrollment to landmark in TEXT and SOFT, respectively). As a non-randomized treatment comparison, we implemented comparative-effectiveness propensity score methodology with weighted Cox modeling. RESULTS Distributions of several clinico-pathologic characteristics differed between groups. Patients who were premenopausal post-chemotherapy in SOFT were younger on average. The median duration of adjuvant chemotherapy was 18 weeks in both groups. There were 231 (12%) BC events after post-landmark median follow-up of about 5 years. Concurrent use of triptorelin with chemotherapy was not associated with a significant difference in post-landmark BCFI compared with sequential triptorelin post-chemotherapy, either in the overall population (HR = 1.11, 95% CI 0.72-1.72; P = 0.72; 4-year BCFI 89% in both groups), or in the subgroup of 692 women <40 years at diagnosis (HR = 1.13, 95% CI 0.69-1.84) who are less likely to develop chemotherapy-induced amenorrhea. CONCLUSION Based on comparative-effectiveness modeling of TEXT and SOFT after about 5 years median follow-up, with limited statistical power especially for the subgroup <40 years, neither detrimental nor beneficial effect of concurrent administration of OFS with chemotherapy on the efficacy of adjuvant therapy that includes chemotherapy was detected.

Abstract
Low birth weight (LBW) is the most important preventable cause in the neonatal period leading to very high neonatal mortality and morbidity in developing countries like Bangladesh. A cross sectional study was conducted in the neonatology ward, Mymensingh Medical College Hospital, Mymensingh from July 2014 to December 2014 to identify the risk factors and immediate hospital outcome of Very Low Birth Weight (VLBW) Appropriate for Gestational Age (AGA) babies in context of present neonatal hospital care standard. Total 100 preterm very low birth weight babies were enrolled and selected by weight, intra uterine growth chart and new ballad score. There is slight preponderance of male babies (64%) over female babies (36%). The overall survival and mortality rate was 50% and 50% respectively in the present study. Mortality is highest (76.47%) in babies whose gestational age 28 weeks and the mortality rate gradually decrease as gestational age increases. Correlation co-efficient (r) between gestational age and number of died is -0.85. It indicates highly opposite relation between the variables, p value (<0.069) which is strong opposite relation. Mortality is highest (66.66%) in babies whose birth weight below1100gm, in comparison to those whose birth weight above 1100gm and correlation co-efficient (CC) r = -0.433 (p<0.466) which is not significant. That means not only birth weight but also other factors are responsible for mortality of very low birth weight baby. Neonatal mortality bears inverse relationship with birth weight and gestational age. This emphasized the need for large scale study which will provide the guideline for appropriate measures to be taken to combat the situation.
