Sarcopenia-The Impact on Physical Capacity of Liver Transplant Patients.

Optimizing patients' condition before liver transplantation (LT) could potentially improve survival of LT patients. We focused on sarcopenia, as a common factor in liver transplant candidates that can impact their cardiopulmonary performance at the point of listing, morbidity, and mortality after LT. We performed a single-center cohort study on 98 consecutive patients with liver cirrhosis who were transplanted between March 2015 and December 2017.

Gray matter volume increases induced by intragastric balloon treatment and their associations with neuroinflammation: A magnetic resonance study.

Objective: We simultaneously performed structural MRI, H magnetic resonance spectroscopy, and whole-body hydration status assessment to evaluate brain changes in patients with morbid obesity treated with intra-gastric balloon (IGB) for six months. We asked, if changes in myo-inositol ratios (marker of neuroinflammation) are related to brain volume increases accompanying IGB-induced weight loss.

Methods: Twenty five patients with morbid obesity (OB, 43.

Liver volume: a point of no return in liver transplantation?

Introduction: In patients with cirrhosis, only a 75% liver volume (LV) is expected compared with age‑matched healthy individuals. Changes in LV might be an indicator of therapeutic effectiveness or disease progression.

Objectives: To establish whether LV is a prognostic factor in chronic liver disease irrespective of etiology and LV impacts the outcomes of liver transplant (LT).

Methods: This was a retrospective observational study performed on 77 HCC patients after liver transplantation.

Unusual post-traumatic aortic rupture in a paraglide pilot - A case report.

Post-traumatic aortic injuries are more common in victims of aircraft accidents than in motor vehicle accidents, and are a leading cause of on-site and delayed mortality, regardless of cause. In this case report, we present a history of a nearly isolated aortic post-traumatic injury in a victim of a paragliding accident. The rarity of this case lies in 2 factors, that is, the lack of the other life-threatening injuries usually present in high-energy accidents, and an unusual, exfoliative type of injury not matching more closely the typical classifications made use of currently in clinical practice.

Tibial stress injuries - location, severity, and classification in magnetic resonance imaging examination.

Results: Most of the patients were young athletic men diagnosed in late stage of TSI.

Intragastric balloon therapy leads to normalization of brain magnetic resonance spectroscopic markers of diabetes in morbidly obese patients.

Elevated brain myo-inositol (m-Ins) concentration (a putative marker of neuroinflammation) has been reported in patients suffering from type 2 diabetes mellitus (T2DM). Obesity alone and T2DM have been found to be associated with a lower concentration of N-acetyloaspartate and N-acetylaspartylglutamate (tNAA, a marker of neuronal integrity, reflecting neuronal loss or metabolic derangement). It is not clear if these changes reverse with weight loss.

Correlation Between Findings of Multislice Helical Computed Tomography (CT), Endoscopic Examinations, Endovascular Procedures, and Surgery in Patients with Symptoms of Acute Gastrointestinal Bleeding.

Background: Endoscopic methods (gastroscopy and colonoscopy) are considered fundamental for the diagnosis of gastrointestinal bleeding. In recent years, multidetector computed tomography (MDCT) has also gained importance in diagnosing gastrointestinal bleeding, particularly in hemodynamically unstable patients and in cases with suspected lower gastrointestinal tract bleeding. CT can detect both the source and the cause of active gastrointestinal bleeding, thereby expediting treatment initiation.

Results of liver transplantation in the Department of General, Transplant and Liver Surgery at the Medical University of Warsaw in patients with chronic hepatitis B and C viruses infection.

Introduction: Cirrhosis related to hepatitis C virus (HCV) and hepatitis B virus (HBV) infection is the most frequent indication for liver transplantation worldwide. Progress in prophylaxis of posttransplant HBV recurrence has led to major improvements in long-term outcomes of patients after liver transplantation. Conversely, impaired posttransplant survival of patients with HCV infection was reported in several studies, mainly due to recurrence of viral infection.

Gall-bladder and hepatoduodenal ligament lymphangioma - case report and literature review.

Lymphangiomas are rare benign lesions of the lymphatic vessels that are most commonly diagnosed in childhood. Intraperitoneal localization is unusual as, typically, they are located in the head and neck areas. In general, abdominal lymphangiomas seem to be asymptomatic, however, patients may occasionally suffer from acute abdominal symptoms, due to intestinal obstruction or peritonitis.

Angiomyolipoma of the liver: analysis of typical features and pitfalls based on own experience and literature.

We present imaging findings (ultrasound, computed tomography, and magnetic resonance imaging) of eight patients with hepatic angiomyolipoma (HAML). The lesions were solitary in seven patients, and one patient had multiple tumors (n=11). Angiomyolipoma, even though a rare liver tumor, should be included in the differential diagnosis in cases of highly vascularized lesion containing a significant amount of fat.
