Objective: Pharmacognostic Screening and evaluate the in-vitro free radical scavenging activity of roots Acacia leucophloea. Methods: Pharmacognostic Standardization, Physico-chemical evaluation of the roots of Acacia leucophloea was carried out to determine its macro-and microscopical characters and also some of its quantitative standards. Microscopical studies were done by using trinocular microscope. Microscopically, root showed cork, cortex, stellar region and calcium oxalate crystals. Petroleum ether, ethanol, aqueous extracts of Acacia leucophloea were prepared, with successive extraction in soxhlet apparatus. Each extract was selected to study the free radical scavenging activity by superoxide scavenging assay method. Results: It was found that aqueous extract contained carbohydrates, glycosides amino acids flavonoids, tannins, alkaloids, steroids; ethanolic extract contained glycosides amino acids flavonoids, tannins, alkaloids, steroids. Ethanolic extract of Acacia leucophloea shows maximam inhibition in superoxide scavenging model. Aqueous extract also showed almost similar activity compared to ethanolic extract), while Petroleum ether extract showed poor inhibition of superoxide scavenging activity. Conclusion: The present study on pharmacognostic standardization, physico and phytochemical evaluation of Acacia leucophloea root might be useful to supplement information about its identification parameters assumed significantly in the way of acceptability of herbal drugs in present scenario lacking regulatory laws to control quality of herbal drugs.

Background: Predicting difficult intubation (DI) is a key challenge, as no single clinical predictor is sufficiently valid to predict the outcome. We evaluated the effectiveness of four upper airway ultrasonographic parameters in predicting DI. The validity of the models using combinations of ultrasonography-based parameters was also investigated. Methods: This prospective, observational, double-blinded cohort trial enrolled 1,043 surgical patients classified as American Society of Anesthesiologists physical status I–III without anticipated difficult airway. Preoperatively, their tongue thickness (TT), invisibility of hyoid bone (VH), and anterior neck soft tissue thickness from the skin to thyrohyoid membrane (ST) and hyoid bone (SH) were measured by sublingual and submandibular ultrasonography. The logistic regression, Youden index, and receiver operator characteristic analysis results were reported. Results: Overall, 58 (5.6%) patients were classified as DI. The TT, SH, ST, and VH had accuracies of 78.4%, 85.0%, 84.7%, and 84.9%, respectively. The optimal values of TT, SH, and ST for predicting DI were > 5.8 cm (sensitivity, 84.5%; specificity; 78.1%; AUC, 0.880), > 1.4 cm (sensitivity, 81%; specificity, 85.2%; AUC, 0.898), and > 2.4 cm (sensitivity, 75.9%; specificity, 85.2%; AUC, 0.885), respectively. VH had a sensitivity and specificity of 72.4% and 85.6% (AUC, 0.790. The AUC values of the five models (with combinations of three or four parameters) ranged from 0.975–0.992. ST and VH had a significant impact on the individual models. Conclusions SH had the best accuracy. Individual parameters showed limited validity. The model including all four parameters offered the best diagnostic value.

Obesity is a growing pandemic across the world. Dietary restrictions and behavior modifications alone have a limited benefit. Bariatric surgery, despite being the current gold standard, has limited acceptance by patients due to cost and associated morbidity. In our review, we have discussed nine original studies describing endoscopic sleeve gastroplasty (ESG). A total of 172 subjects successfully underwent ESG. Of 65 subjects with follow up data, 95.4% (62/65) had intact gastric sleeve confirmed via esophagogastroduodenoscopy or oral contrast study at the end of study specific follow up interval (the longest being 6 months). Individual studies reported a technical success rate for intact gastric sleeve from as low as 50% to as high as 100%. A statistically significant p < 0.05) weight loss was reported in seven of the eight studies with available data. None of the patients experienced any intra-procedure complications, and approximately 2.3% (4/172) of patients experienced major post-procedure complications; however, no mortality was reported. Majority of the studies reported relatively high incidence of minor post-procedure complications, which improved with symptomatic treatment alone. Good patient tolerance with comparable clinical efficacy in achieving and sustaining desired weight loss makes ESG an attractive option to consider among other bariatric therapies.

The histologic analysis of gastrointestinal stromal tumors (GISTs) is a common method to detect the mitotic activity and to subsequently determine the risk of GISTs for malignancy. The potential false negative error due to inadequate yield of specimens and actual determination of malignancy risk requires analysis of the whole tumor. We aimed to assess the role of contrast enhanced endoscopic ultrasound (CE-EUS) in the management of GISTs. Two authors individually did review of English literatures to identify nine peer-reviewed original articles using keywords- contrast endoscopic ultrasound, GIST and submucosal tumor. Studies were heterogeneous in their aims looking either at differentiating submucosal lesions from GISTs, estimating malignant potential of GISTs with histologic correlation or studying the role of angiogenesis in malignant risk stratification. CE-EUS had moderate to high efficacy in differentiating GISTs from alternative submucosal tumors. CE-EUS had a higher sensitivity than EUS-guided fine needle aspiration, contrast computed tomography and Doppler EUS for detection of neo-vascularity within the GISTs. However, the evidence of abnormal angiogenesis within GIST as a prognostic factor needs further validation. CE-EUS is a non-invasive modality, which can help differentiate GISTs and provide valuable assessment of their perfusion patterns to allow better prediction of their malignant potential but more experience is needed.

Gastric outlet obstruction, afferent or efferent limb obstruction, and biliary obstruction among patients with altered anatomy often require surgical intervention which is associated with significant morbidity and mortality. Endoscopic dilation for benign etiologies requires multiple sessions, whereas self-expandable metal stents used for malignant etiologies often fail due to tumor in-growth. Lumen apposing metal stents, placed endoscopically with the intent of creating a de-novo gastrointestinal anastomosis bypassing the site of obstruction, can potentially achieve similar efficacy, with a much lower complication rate. In our study cohort (n=79), the composite technical success rate and clinical success rate was 91.1% (72/79) and 97.2% (70/72), respectively. Five different techniques were used: 43% (34/79) underwent the balloon-assisted method, 27.9% (22/79) underwent endoscopic ultrasound-guided balloon occluded gastro-jejunostomy bypass, 20.3% (16/79) underwent the direct technique, 6.3% (5/79) underwent the hybrid rendezvous technique, and 2.5% (2/79) underwent natural orifice transluminal endoscopic surgery (NOTES)-assisted procedure. All techniques required an echoendoscope except NOTES. In all, 53.2% (42/79) had non-cautery enhanced Axios stent, 44.3% (35/79) had hot Axios stent, and 2.5% (2/79) had Niti-S spaxus stent. Symptom-recurrence was seen in 2.8%, and 6.3% had a complication (bleeding, abdominal pain or peritonitis). All procedures were performed by experts at centers of excellence with adequate surgical back up.

Background/Aims: Liver cirrhosis is an important cause of morbidity and mortality globally. Every episode of decompensation and hospitalization reduces survival. We studied the clinical profile and long-term outcomes comparing alcohol-related cirrhosis (ALC) and non-ALC.
Methods: Cirrhosis patients at index hospitalisation (from January 2010 to June 2017), with ≥1 year follow-up were included.
Results: Five thousand and one hundred thirty-eight cirrhosis patients (age, 49.8±14.6 years; male, 79.5%; alcohol, 39.5%; Child-A:B:C, 11.7%:41.6%:46.8%) from their index hospitalization were analysed. The median time from diagnosis of cirrhosis to index hospitalization was 2 years (0.2–10). One thousand and seven hundred seven patients (33.2%) died within a year; 1,248 (24.3%) during index hospitalization. 59.5% (2,316/3,890) of the survivors, required at least one readmission, with additional mortality of 19.8% (459/2,316). ALC compared to non-ALC were more often (P<0.001) male (97.7% vs. 67.7%), younger (40–50 group, 36.2% vs. 20.2%; P<0.001) with higher liver related complications at baseline, (P<0.001 for each), sepsis: 20.3% vs. 14.9%; ascites: 82.2% vs. 65.9%; spontaneous bacterial peritonitis: 21.8% vs. 15.7%; hepatic encephalopathy: 41.0% vs. 25.0%; acute variceal bleeding: 32.0% vs. 23.7%; and acute kidney injury 30.5% vs. 19.6%. ALC patients had higher Child-Pugh (10.6±2.0 vs. 9.0±2.3), model for end-stage liver-disease scores (21.49±8.47 vs. 16.85±7.79), and higher mortality (42.3% vs. 27.3%, P<0.001) compared to non-ALC.
Conclusions One-third of cirrhosis patients die in index hospitalization. 60% of the survivors require at least one rehospitalization within a year. ALC patients present with higher morbidity and mortality and at a younger age.

AIM: To study the in vivo anti-inflammatory activity of Tabernaemontana divaricata leaf extract on male albino mice. METHODS: Aqueous decoction and methanol leaf extracts were tested for their ability to reduce croton oil-induced edema in the mouse ear after topical application. The methanol leaf extract dose-dependently inhibited the croton oil-induced ear edema in mice (ID50 <500 μg·cm(-2)). A bioassay-guided liquid-liquid fractionation of this methanol extract gave four active fractions: water insoluble (F1), hexane (F2), ethyl acetate (F3) and water (F4). RESULTS: The hexane fraction showed a very high activity (42.1% inhibition at 0.7 μg·cm(-2)) as compared to the control. The other fractions were less active (F1: 56.1% at 506.2 μg·cm(-2); F3: 57.3% at 289.3 μg·cm(-2); and F4: 31.9% for 203.8 μg·cm(-2)) while indomethacin gave 48.8% of inhibition at 90 μg·cm(-2). The activity of F1 and F3 may be at least in part explained by the presence of anti-inflammatory flavonoids, while the activity was not correlated to the tannin contents. No compounds were detected in the most active F2 fraction. CONCLUSIONS The results give a rational support to the traditional use of T. divaricata in tropical India as anti-inflammatory agent.
