Acute-on-chronic liver failure (ACLF) is a severe form of alcoholic hepatitis (SAH). We aimed to study the natural course, response to corticosteroids (CS), and the role of the Asian Pacific Association for the Study of Liver (APASL) research consortium (AARC) score in determining clinical outcomes in AH patients.Prospectively collected data from the AARC database were analyzed.Of the 1249 AH patients, (aged 43.8 ± 10.6 years, 96.9% male, AARC score 9.2 ± 1.9), 38.8% died on a 90 day follow-up. Of these, 150 (12.0%) had mild-moderate AH (MAH), 65 (5.2%) had SAH and 1034 (82.8%) had ACLF. Two hundred and eleven (16.9%) patients received CS, of which 101 (47.87%) were steroid responders by day 7 of Lille's model, which was associated with improved survival [Hazard ratio (HR) 0.15, 95% CI 0.12-0.19]. AARC-ACLF grade 3 [OR 0.28, 0.14-0.55] was an independent predictor of steroid non-response and mortality [HR 3.29, 2.63-4.11]. Complications increased with degree of liver failure [AARC grade III vs. II vs I], bacterial infections [48.6% vs. 37% vs. 34.7%; p 0.001); extrahepatic organ failure [66.9% vs. 41.8% vs. 35.4%; p 0.001] respectively. The AARC score better discriminated 90-day mortality. Harrell's C-index was 0.72 compared to other scores.Nearly 4 of 5 patients with AH present with ACLF. Such patients have a higher risk of infections, organ failures, lower response to CS, and higher mortality. Patients with AH and ACLF with AARC grade 3 should be considered for an early liver transplant.

Osteomyelitis around the knee joint if not treated in time will lead to degeneration of knee joint and those patients will have symptoms for which a total knee arthroplasty would be indicated. Very few studies are available in the literature, in which the surgeons have performed primary total knee arthroplasty in cases of previous quiescent osteomyelitis around the knee. The objective of these reports is to investigate whether prior quiescent osteomyelitis around the knee joint would result in high rate of recurrence of infection after primary total knee arthroplasty? Which antibiotics should be used if intraoperative cultures are negative in patients with quiescent osteomyelitis and what would be the duration of antibiotics? Here we present case reports of 2 patients who underwent total knee arthroplasty after previous distal femur osteomyelitis and their functional outcomes aftertotal knee arthroplasty with a follow-up period of 2 years. Both the patients preoperatively were limited to indoor ambulation and had signicant difculties with stair climbing, reported signicant improvement in climbing up and down stairs, ambulatory distance and activities of daily living in the post-operative period. None of the patients had clinical signs of deep prosthetic joint infection at 2 years follow-up

BACKGROUND: Saroglitazar is a novel, dual peroxisome proliferator-activated receptors-α/γ agonist and is being investigated for the treatment of nonalcoholic fatty liver disease (NAFLD). PATIENTS AND METHODS: Consecutive overweight (body mass index [BMI] >23 kg/m(2)) patients of NAFLD, diagnosed based on controlled attenuation parameter (CAP) >248 dB/m, and attending the outpatient department of a tertiary care centre in New Delhi, were enrolled. Patients with cirrhosis (liver stiffness measurement [LSM] >13.5 kPa) and those with concomitant liver disease due to other aetiologies (alcohol, viral, etc.) were excluded. All patients received saroglitazar 4 mg/day; in addition, they were advised to reduce weight and were counselled regarding diet and exercise. At 3-month follow-up, patients were categorized into those who were able to reduce ≥5% body weight and those who could n’ot, and both these groups were compared. RESULTS: A total of 91 patients (median age 45 years [range 18–66 years]; 81% men) were included in the study. The median BMI was 29.3 kg/m(2) (range 23.6–42.2 kg/m(2)). The baseline median (range) aspartate transaminase, alanine transaminase, gamma glutamyl transferase, LSM and CAP values were 40 IU/dL (range 22–144 IU/dL), 48 IU/dL (range 13–164 IU/dL), 42 IU/dL (range 4–171 IU/dL), 6.7 kPa (range 3.6–13.1 kPa), and 308 dB/m (range 249–400 dB/m). All patients tolerated saroglitazar well. At 3-month, 57 patients (63%) were able to reduce ≥5% weight, whereas in the remaining 34 patients (37%), the weight reduction was

Sentiment can be defined as a view or opinion that is held or expressed. Whereas, sentiment analysis (SA) is a process of computationally identifying and categorizing opinions expressed in a piece of textual content, particularly to decide the writer's attitude towards a particular topic, product or issue. SA also known as opinion mining is widely used in many domains such as products, services, issues and politics to analyze user’s behaviors or opinion regarding the related topics. Sentiment analysis is used to analyse the review of product, political issues, reviews on the social media such as face book, twitter, movies etc. where the different users can provide feedback and analyze it. It is also important for Business development by providing the product review and knows exactly what the customer wants. In this work, we have reviewed the latest developments in sentiment analysis.

Background A variation in the measurement of ABO antibody titer has been seen among different laboratories due to lack of standardization. In our study, we aim to evaluate automated ABO isoagglutinin titer measurements by erythrocytes magnetized technology (EMT) and compare with conventional tube technique (TT). Methods We performed ABO isoagglutinin titration on samples received in a reference laboratory during a period of 2 months. A total of 134 tests for immunoglobulin G (IgG) titer and 116 for immunoglobulin M (IgM) for anti-A or anti-B were included in the study. Samples were processed for ABO isoagglutination titers by both TT and EMT by QWALYS-3 (DIAGAST, France). Microsoft Excel was used to compile data, for all calculations, and to draw graphs and plots. The number and percentage of cases within ±1, ±2, or ±3 titer difference (TT-EMT) were calculated. Results Median titers and their ranges obtained by EMT were higher or equal to those by TT for all IgM and IgG ABO-antibodies in all blood group (BGs), except anti-A IgM in (BG) O that was lower by EMT (32 [4:128]) than TT (48 [8:256]). One twenty one (121/134, 90.3%) cases of IgG titer showed an agreement by both methods (within ± one titer difference). One hundred seven cases (107/116, 92.2%) for IgM titer were within one titer difference by both the methods. Conclusion Results of titration by EMT-based automated instrument QWALYS-3 and conventional TT may vary by one titer dilution in the majority of cases. Use of consistent method for patient management is, therefore, advised.

Limited data exist regarding outcomes of acute variceal bleeding (AVB) in patients with acute-on-chronic liver failure (ACLF), especially in those with hepatic failure. We evaluated the outcomes of AVB in patients with ACLF in a multinational cohort of APASL ACLF Research Consortium (AARC).Prospectively maintained data from AARC database on patients with ACLF who developed AVB (ACLF-AVB) was analysed. This data included demographic profile, severity of liver disease, and rebleeding and mortality in 6 weeks. These outcomes were compared with a propensity score matched (PSM) cohort of ACLF matched for severity of liver disease (MELD, AARC score) without AVB (ACLF without AVB).Of the 4434 ACLF patients, the outcomes in ACLF-AVB (n = 72) [mean age-46 ± 10.4 years, 93% males, 66% with alcoholic liver disease, 65% with alcoholic hepatitis, AARC score: 10.1 ± 2.2, MELD score: 34 (IQR: 27-40)] were compared with a PSM cohort selected in a ratio of 1:2 (n = 143) [mean age-44.9 ± 12.5 years, 82.5% males, 48% alcoholic liver disease, 55.7% alcoholic hepatitis, AARC score: 9.4 ± 1.5, MELD score: 32 (IQR: 24-40)] of ACLF-without AVB. Despite PSM, ACLF patients with AVB had a higher baseline HVPG than without AVB (25.00 [IQR: 23.00-28.00] vs. 17.00 [15.00-21.75] mmHg; p = 0.045). The 6-week mortality in ACLF patients with or without AVB was 70.8% and 53.8%, respectively (p = 0.025). The 6-week rebleeding rate was 23% in ACLF-AVB. Presence of ascites [hazard ratio (HR) 2.2 (95% CI 1.03-9.8), p = 0.026], AVB [HR 1.9 (95% CI 1.2-2.5, p = 0.03)], and MELD score [HR 1.7 (95% CI 1.1-2.1), p = 0.001] independently predicted mortality in the overall ACLF cohort.Development of AVB confers poor outcomes in patients with ACLF with a high 6-week mortality. Elevated HVPG at baseline represents a potential risk factor for future AVB in ACLF.

Liver stiffness measurement using transient elastography (TE-LSM) is a promising noninvasive alternative to hepatic venous pressure gradient (HVPG) for diagnosing clinically significant portal hypertension (CSPH). However, previous studies have yielded conflicting results. We evaluated the correlation between TE-LSM and HVPG and the performance of TE-LSM in diagnosing CSPH (HVPG ≥ 10 mmHg).We conducted a systematic review and meta-analysis by searching PubMed and Scopus databases for relevant literature evaluating the clinical usefulness of TE for diagnosing CSPH in patients with chronic liver disease.Twenty-six studies (4337 patients with valid TE and HVPG) met our inclusion criteria. The median correlation coefficient of TE with HVPG was 0.70 (range 0.36-0.86). The weighted mean of optimal cut-off of liver stiffness value for diagnosing CSPH was 22.8 kPa (95% CI 22.7-23.0 kPa). The summary sensitivity and specificity were 79% (95% CI 74-84%) and 88% (95% CI 84-91%), respectively. The area under the hierarchical summary receiver operating characteristic (HSROC) curve was 0.91 (95% CI 0.88-0.93) according to the bivariate model. One limitation of the study was significant heterogeneity in the results of summary sensitivity and specificity (ILiver stiffness measurement using TE correlates well with HVPG, and a liver stiffness cut-off value of 22.8 kPa shows a high accuracy for diagnosing CSPH. Thus, use of TE should be integrated into clinical practice for noninvasive diagnosis of CSPH.

Acute liver failure (ALF) is not an uncommon complication of a common disease such as acute hepatitis. Viral hepatitis followed by antituberculosis drug-induced hepatotoxicity are the commonest causes of ALF in India. Clinically, such patients present with appearance of jaundice, encephalopathy, and coagulopathy. Hepatic encephalopathy (HE) and cerebral edema are central and most important clinical event in the course of ALF, followed by superadded infections, and determine the outcome in these patients. The pathogenesis of encephalopathy and cerebral edema in ALF is unique and multifactorial. Ammonia plays a crucial role in the pathogenesis, and several therapies aim to correct this abnormality. The role of newer ammonia-lowering agents is still evolving. These patients are best managed at a tertiary care hospital with facility for liver transplantation (LT). Aggressive intensive medical management has been documented to salvage a substantial proportion of patients. In those with poor prognostic factors, LT is the only effective therapy that has been shown to improve survival. However, recognizing suitable patients with poor prognosis has remained a challenge. Close monitoring, early identification and treatment of complications, and couseling for transplant form the first-line approach to manage such patients. Recent research shows that use of dynamic prognostic models is better for selecting patients undergoing liver transplantation and timely transplant can save life of patients with ALF with poor prognostic factors.
