Stress hyperglycemia ratio, rather than admission blood glucose, predicts in-hospital mortality and adverse outcomes in moderate-to severe COVID-19 patients, irrespective of pre-existing glycemic status.

AIM: To compare admission-blood-glucose (ABG) or stress-hyperglycemia-ratio (SHR) performs better in predicting mortality and worse outcomes in COVID-19 patients with (DM) and without known Type 2 Diabetes Mellitus (UDM). METHODS: ABG and SHR were tested for 451 patients with moderate-severe COVID-19 infection [DM = 216,47.9%; pre-diabetes = 48,10.6%, UDM = 187,41.4%],who were followed-up to look for in-hospital-mortality (primary outcome) and secondary outcomes (ICU stay or mechanical ventilation, hospital-acquired-sepsis and multiple organ dysfunction syndrome [MODS]). Those with and without SHR ≥ 1.14 were compared; logistic regression was done to identify predictors of outcomes, with subgroup analysis based on pre-existing DM status and COVID-19 severity. RESULTS: Those who died (n = 131) or developed ≥ 1 secondary outcomes (n = 218) had higher prevalence of SHR ≥ 1.14, ABG ≥ 180 mg/dl and higher median SHR (pall < 0.01). Those with SHR ≥ 1.14 had higher mortality (53.7%), higher incidence of ≥ 1 secondary outcomes (71.3%) irrespective of pre-existing diabetes status. SHR ≥ 1.14, but not ABG ≥ 180 was an independent predictor of mortality in the whole group (OR: 7.81,4.07-14.98), as also the DM (OR:10.51,4.34-25.45) and UDM (5.40 (1.57-18.55) subgroups. SHR ≥ 1.14 [OR: 4.41 (2.49-7.84)] but not ABG ≥ 180 could independently predict secondary outcomes AUROC of SHR in predicting mortality was significantly higher than ABG in all subgroups. CONCLUSION: SHR better predicts mortality and adverse outcomes than ABG in patients with COVID-19, irrespective of pre-existing chronic glycemic status.

Safety and outcomes of pre-operative portal vein embolization using N-butyl cyanoacrylate (Glue) in hepatobiliary malignancies: A single center retrospective analysis.

AIMS AND OBJECTIVES: To evaluate the outcome of preoperative portal vein embolization (PVE) using N-butyl cyanoacrylate (NBCA) for change in future liver remnant (FLR) volume, biochemical changes, and procedure-related complications. The factors affecting FLR hypertrophy and the rate of resection was also evaluated for this cohort. MATERIALS AND METHODS: From 2012 to 2017, PVE utilizing NBCA mixed with lipiodol (1:4) was performed using percutaneous approach in 28 patients with hepatobiliary malignancies with low FLR. All patients underwent volumetric computed tomography (CT) assessment before and at 3-5 weeks after PVE and total liver volume (TLV), FLR volume, and FLR/TLV ratio, changes in portal vein diameter and factors affecting FLR were evaluated. Complications and the resectability rate were recorded and analyzed. RESULT: PVE was successful in all 28 patients. The mean FLR increased by 52% ± 32% after PVE (P < 0.0001). The FLR/TLV ratio was increased by 14.2% ± 2.8% (P < 0.001). Two major complications were encountered without any impact on surgery. There was no significant change seen in liver function test and complete blood counts after PVE. Eighteen patients (64.28%) underwent hepatic resection without any liver failure, and only three patients developed major complication after surgery. Remaining ten patients did not undergo surgery because of extrahepatic metastasis detected either on follow-up imaging or staging laparotomy. Patients with diabetes showed a lower rate of hypertrophy (P < 0.05). CONCLUSION: Preoperative PVE with NBCA is safe and effective for increasing FLR volume in patients of all age group and even in patients with an underlying liver parenchymal disease with hepatobiliary malignancy. Lesser hypertrophy was noted in patients with diabetes. A reasonable resectability was achieved despite having a high rejection in gall bladder cancer subgroup due to rapid disease progression.

Anatomic Recanalization of Hepatic Vein and Inferior Vena Cava versus Direct Intrahepatic Portosystemic Shunt Creation in Budd-Chiari Syndrome: Overall Outcome and Midterm Transplant-Free Survival.

PURPOSE: To assess overall outcome and midterm transplant-free survival of patients with Budd-Chiari syndrome (BCS) undergoing radiologic interventions including anatomic recanalization of the hepatic vein (HV) and inferior vena cava (IVC) and direct intrahepatic portosystemic shunt (DIPS) creation, both as combined and as independent groups. MATERIALS AND METHODS: From November 2010 to October 2014, 136 patients with BCS were treated with HV/IVC recanalization (group 1) or DIPS creation (group 2). Both groups were periodically analyzed for stent patency on Doppler ultrasound, clinical outcome, biochemical parameters, and survival until death, liver transplantation, or last clinical evaluation. RESULTS: Actuarial transplant-free survival for the entire cohort was 94% at 1 year and 5 years with no significant difference in overall survival. There was significant biochemical improvement in group 1 with decrease in mean serum bilirubin level (1.8 mg/dL to 1.4 mg/dL, P < .011), mean serum aspartate aminotransferase (48.6 IU/L to 33.2 IU/L, P < .05), and mean serum alanine aminotransferase (38.7 IU/L to 28.5 IU/L) and increase in mean serum albumin level (3.2 g/dL to 3.45 g/dL, P < .001) after 3 and 24 months. There were 4 deaths in each group at 1-year follow-up; all 4 patients had acute fulminant BCS at presentation. CONCLUSIONS: Radiologic interventions for BCS lead to remarkable improvement of liver function and a good overall outcome and midterm transplant-free survival. Patients receiving anatomic recanalization show improved liver synthetic functions compared with patients treated with DIPS.
