Risk Factors, Pathogens, and Outcomes of Ventilator-Associated Pneumonia in Non-Cardiac Surgical Patients: A Retrospective Analysis.

Ventilator-associated pneumonia (VAP) is a critical hospital-acquired infection following non-cardiac surgeries, leading to poor outcomes. This study identifies VAP risk factors in non-cardiac surgical patients and determines the causative pathogens. A retrospective analysis with 1:4 propensity-score matching was conducted on patients in a surgical intensive care unit (ICU) from 2010 to 2020 at a private tertiary medical center.

Gram-negative bacterial infections in surgical intensive care unit patients following abdominal surgery: high mortality associated with Stenotrophomonas maltophilia infection.

Background: Stenotrophomonas maltophilia, a multidrug-resistant gram-negative bacteria (GNB), is an emerging nosocomial pathogen. This study assessed the clinical outcomes of GNB infections in surgical intensive care unit (SICU) patients post-abdominal surgery, focusing on the differences between S. maltophilia and other GNBs, including Pseudomonas aeruginosa.

The incidence and risk factors of proximal lower extremity deep vein thrombosis without pharmacologic prophylaxis in critically ill surgical Taiwanese patients: A prospective study.

Background: Venous thromboembolism (VTE) in critically ill patients has been well-studied in Western countries. Many studies have developed risk assessments and established pharmacological protocols to prevent deep venous thrombosis (DVT). However, the DVT rate and need for pharmacologic VTE prophylaxis in critically ill Taiwanese patients are limited.

Prognostic factors for critically ill surgical patients with unplanned intensive care unit readmission: Developing a novel predictive scoring model for predicting readmission.

Background: Unplanned readmission to the surgical intensive care unit has been demonstrated to worsen patient outcomes. Our objective was to identify risk factors and outcomes associated with unplanned surgical intensive care unit readmission and to develop a predictive scoring model to identify patients at high risk of readmission.

Methods: We retrospectively analyzed patients admitted to the surgical intensive care unit (2020-2021) and categorized them as either with or without unplanned readmission.

Can Microscopic Biliary Reconstruction Reduce Biliary Complication Rate in ABO-Incompatible Adult Living Donor Liver Transplantation?

BACKGROUND With the introduction of rituximab, ABO-incompatible (ABOi) living donor liver transplantation (LDLT) has been considered a feasible and safe procedure to overcome the shortage of organ donors. However, higher biliary complication rates remain an unresolved problem in the ABOi group. In our center, biliary anastomosis has been done with microscopic biliary reconstruction (MBR), which effectively reduced the biliary complication rate.

Excellent Outcome in Living Donor Liver Transplantation: Treating Patients With Acute-on-Chronic Liver Failure.

Acute-on-chronic liver failure (ACLF) is a fatal condition, and liver transplantation (LT) is a vital option for these patients. However, the result of living donor LT (LDLT) for ACLF is not well investigated. This study investigated the outcomes of LDLT in patients with ACLF compared with patients without ACLF.

Cerebrospinal Fluid Cultures in Traumatic Brain Injury: Is It Worth It? A Two-Center Study.

Patients with traumatic brain injury (TBI) frequently develop leukocytosis, fever, and tachycardia that may lead to extensive medical investigations to rule out an infectious process. Cerebrospinal fluid (CSF) is often acquired during this workup, however, the utility of this practice has not been studied previously. We hypothesized that CSF cultures would unlikely yield positive results in patients with TBI.

A Systems-based Approach to Reduce Deep Venous Thrombosis and Pulmonary Embolism in Trauma Patients.

Background: Venous thromboembolism (VTE) in trauma patients carries significant morbidity and mortality. We previously described how titrating enoxaparin dosing by anti-Xa trough levels was associated with a lower VTE rate. We combined this strategy with a higher initial enoxaparin dose for a majority of patients and modified the electronic medical record (EMR) to encourage immediate dosing.

Which Trauma Patients Require Lower Enoxaparin Dosing for Venous Thromboembolism Prophylaxis?

Trauma patients have a high risk for venous thromboembolism (VTE) such that an increased enoxaparin dose is necessary to reduce related complications. Given that most trauma patients require an enoxaparin dose of at least 40 mg every 12 hours for VTE prophylaxis, we sought to identify which patients require enoxaparin 30 mg every 12 hours and hypothesized that both weight and low creatinine clearance (CrCl) would more likely determine enoxaparin dosing than age, body mass index (BMI), or body surface area (BSA). Single institution data were collected on trauma patients between August 2014 and February 2018 to compare trauma patients who required enoxaparin 30 mg to those who required ≥40 mg every 12 hours.

Early positive fluid balance is predictive for venous thromboembolism in critically ill surgical patients.

Background: Positive fluid balance (FB) in the intensive care unit (ICU) may be a marker for increased venous thromboembolism (VTE) risk. We hypothesized that an early positive fluid balance (FB) would be associated with increased VTE occurrence.

Methods: A single-center retrospective review of surgical ICU patients was conducted from May 2011 to December 2014.

Comparative analysis of the drug-drug interaction between immunosuppressants, safety and efficacy of rifabutin from rifampicin-based Anti-TB treatment in living donor liver transplant recipients with active tuberculosis.

Background: The Interaction between anti-tuberculous and immunosuppressive drugs which may increase the risk of graft rejections is a major challenge in managing transplant recipients with tuberculosis (TB). Instead of rifampicin (RFM), most guidelines recommended the use of rifabutin (RFB) because of its reduced capacity to induce immunosuppressant metabolism while maintaining the same efficacy as RFM against TB. However, there has been no available data directly comparing the outcome of RFB from RFM-based anti-TB regimens in liver transplant patients with TB.

Background: Tumor histology affects outcome after liver transplantation (LT) for hepatocellular carcinoma (HCC). This study explores the association between F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) and tumor histology in living donor liver transplantation (LDLT) recipients and their outcome.

Materials And Methods: Two hundred fifty-eight patients with primary liver tumors who underwent FDG-PET before LDLT were enrolled in this retrospective study.

Endoscopic injection sclerotherapy for pediatric bleeding esophageal varices complicated by gastric vein, main portal vein, splenic mesenteric junction, and splenic vein occlusion: a case report.

Background: Endoscopic injection sclerotherapy (EIS) is a life-saving procedure for pediatric patients with bleeding gastric varices (GV) associated with advanced liver cirrhosis and severe portal hypertension. Because of the lack of an endoscopic banding ligation device for pediatric patients, EIS is usually performed for bleeding esophageal varices (EV) in infants with congenital biliary atresia.

Case Presentation: We present a case of a 15-month-old female infant with type I biliary atresia with jaundice (total serum bilirubin, 22.

Clinical Outcomes of Tuberculosis in Recipients After Living Donor Liver Transplantation.

BACKGROUND This study aimed to determine clinical outcomes using various drugs during tuberculosis (TB) treatment among living donor liver transplant (LDLT) recipients with TB and to assess the impact of performing LDLT in patients with active TB at the time of LDLT. MATERIAL AND METHODS Out of 1313 LDLT performed from June 1994 to May 2016, 26 (2%) adult patients diagnosed with active TB were included in this study. Active TB was diagnosed using either TB culture, PCR, and/or tissue biopsy.

Complications of percutaneous liver biopsy in living donor liver transplantation: Two case reports.

Rationale: According to previously published studies, major complications arising from a percutaneous liver biopsy are rare and occur in less than 0.1% of cases. This report describes an approach to percutaneous liver biopsy that can help avoid damage to the liver in a living donor liver transplantation (LDLT) setting.

Assessment of relevant factors with respect to psychosocial properties in potential living donor candidates before liver transplantation.

Background: Living donor liver transplantation (LDLT) has been developed as one of gold standard treatments for end-stage liver disease. Mental health is a required selection criterion for adult living liver donors and may influence the quality of life after operation.

Patients And Methods: A total of 1,210 potential living donor candidates for liver transplantation (LT) underwent psychosocial evaluation that included a semi-structured interview, multi-choice self-reported inventory (Beck Depression Inventory-2nd edition [BDI-II], Beck Anxiety Inventory [BAI]), and the family APGAR (Adaptability, Partnership, Growth, Affection, Resolve) index.

Rebound thymic hyperplasia after liver transplantation for a child with biliary atresia; a case report.

The thymus gland possesses the ability to regrow in children leading to a newly developed anterior mediastinal mass. This condition may represent a rebound phenomenon during recovery from a stressful event such as post-chemotherapy and hence was described as RTH. RTH after LT has not been well documented.

The surgical challenges of salvage living donor liver transplantation for Hepatocellular carcinoma; The cumulative experience of 100 cases - A retrospective cohort study and a propensity score analysis.

Background: Hepatocellular carcinoma (HCC) is increasingly managed by liver resection first then salvage liver transplantation in case of recurrence within accepted criteria. Many reports compared the safety of the salvage against the primary surgery in the setting of deceased donation but the difference in case of living donation is not sufficiently defined. Salvage living donor liver transplantation (SLDLT) is believed to be a more challenging surgery than primary living donor liver transplantation (PLDLT) due to operative field adhesions, in addition to the inherent difficulties particularly short vasculobiliary stumps.

Liver Transplantation for High Risk Hepatocellular Carcinoma After Liver Resection: A Sequential or Salvage Approach?

BACKGROUND Liver transplantation (LT) is the best radical treatment of hepatocellular carcinoma (HCC). Salvage liver transplantation (SalvLT) provides good outcomes for recurrent HCC cases after initial curative liver resection (LR). However, the salvage strategy is not feasible in all situations due to aggressive recurrences.

Active immunization for prevention of De novo hepatitis B virus infection after adult living donor liver transplantation with a hepatitis B core antigen-positive graft.

De novo hepatitis B virus (DNHB) infections may occur in recipients who do not receive prophylaxis after liver transplantation (LT) with antibody to hepatitis B core antigen (anti-HBc)-positive donor grafts. Active immunization has been shown to prevent DNHB in pediatric recipients. Our aim is to investigate the efficacy of HBV vaccination for preventing DNHB in adult living donor liver transplantation (LDLT).

Central Hepatectomy Still Plays an Important Role in Treatment of Early-Stage Centrally Located Hepatocellular Carcinoma.

Background: Surgical management of centrally located hepatocellular carcinoma (CL-HCC) poses a great challenge. Major hepatectomy (MH) might compromise future remnant liver volume (FRLV), while the long-term benefits of central hepatectomy (CH) had not been well demonstrated.

Methods: Consecutive patients with early-stage CL-HCC who underwent liver resection were enrolled.

P4 Stump Approach for Intraoperative Portal Vein Stenting in Pediatric Living Donor Liver Transplantation: An Innovative Technique for a Challenging Problem.

Objective: The aim of this study was to evaluate the utility of the P4 stump stenting approach for treating portal vein (PV) complications in pediatric living donor liver transplantation (LDLT).

Background: PV complications cause significant morbidity and mortality in pediatric LDLT. Biliary atresia in the backdrop of pathological PV hypoplasia and sclerosis heightens the complexity of PV reconstruction.
