Hepatitis C virus infection in hemodialyzed patients.
2007
In spite of our present improved knowledge of the epidemiology and pathways of contamination of the hepatitis C virus (HCV), infection still remains a public health problem. One category of patients who have suffered greatly from the consequences of HCV infection is certainly that of hemodialysis patients. In the past, in fact, their need for transfusions exposed these patients to infection and, as a result, subjects on dialysis for over 15 years are today paying the price for those inevitable transfusions, as the virus and its pathways of contagion were unknown then. However, still today, albeit at a much lower prevalence, even subjects with a shorter dialysis age present a higher prevalen…
Associated Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) Registry: What Have We Learned?
2020
In 2007, the first associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure was performed in Regensburg, Germany. ALPPS is a variation of two-stage hepatectomy to induce rapid liver hypertrophy allowing the removal of large tumors otherwise considered irresectable due to a too small future liver remnant. In 2012, the international ALPPS registry was created, and it now contains more than 1,000 cases. During the past years, improved patient selection and refinements in operative techniques, in particular, less invasive approaches such as Partial ALPPS, Tourniquet ALPPS, Ablation-assisted ALPPS, Hybrid ALPPS or Laparoscopic or Robotic approaches, have resu…
Effects of dietary conjugated linoleic acids in the control of adiposity and obesity‐related disorders
2007
The body fat-lowering effect of conjugated linoleic acids (CLA) in experimental animals has attracted much interest because of the potential use of CLA as weight loss agents in humans. The objective of this review was to give an overview of the results from human intervention trials. The review also addresses experimental studies in animal models and in cultured cells. CLA appear to provoke fat mass loss and an increase of fat-free mass in rodents, but the results in humans are inconsistent and much less clear than in rodents. Thus, the results of studies in humans do not support a body fat-lowering effect of CLA. There are indications from animal studies that the trans-10, cis-12 CLA isome…
Graft rinse prior to reperfusion in liver transplantation: literature review and online survey within the Eurotransplant community
2015
Graft rinse prior reperfusion in liver transplantation (LT) is believed to reduce the incidence of postreperfusion syndrome and improve clinical outcome. A MEDLINE search was performed to obtain a comprehensive review of the published literature dealing with graft rinse in LT. Moreover, all thirty-four LT centers in the Eurotransplant (ET) region were invited to participate in an online survey to whether or not graft rinse is performed and whether further research in the field is needed. Seventeen reports have been found to investigate graft rinse protocols in 1894 LT recipients. Eighteen of the thirty centers that participated in the online survey performed graft rinse prior reperfusion in…
Group psychoeducation with relaxation for severe fear of childbirth improves maternal adjustment and childbirth experience – a randomised controlled …
2014
Previous studies on the treatment of women with fear of childbirth have focused on the delivery mode. Women with fear of childbirth often suffer from anxiety and/or depression, and treatment therefore also needs to target postnatal psychological well-being and the early mother-infant relationship.Three hundred and seventy-one nulliparous women out of 4575 scored ≥100 in prospective screening (Wijma Delivery Expectancy Questionnaire, W-DEQ-A), indicating severe fear of childbirth. These women were randomised to psychoeducative group intervention with relaxation (n = 131; six sessions during pregnancy, one postnatal) or to conventional care (n = 240) by community nurses (referral if necessary…
Dilation of the ductus venosus by stent implantation increases placental blood perfusion in fetal sheep.
2006
The reduction of resistance to flow in the ductus venous (DV) and a decrease of blood supply to the liver serve for the survival of the fetus during hypoxia. The present study investigated the influence of the increased diameter of the DV on placental blood perfusion.In 15 ewes with twin pregnancies at gestational ages of 117 +/- 4 days, a stent (4 or 5 mm) was placed into the DV of 1 twin (DV(stent) group) under ultrasound guidance. Blood flow rates in the umbilical vein (UV) and DV of both fetuses were measured using Doppler ultrasound. Eight pairs of twin fetuses were included for the final analysis.The dilatation of the DV increased the blood flow volume rate passed through the DV from …
Official Statement of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) on Electronic Cigarettes and IQOS®.
2019
The use of novel tobacco products, particularly the electronic cigarette (EC) and partial tobacco combustion devices (HnB systems: Heat not Burn), has increased exponentially, particularly among adolescents and young people. The health authorities and scientific societies have shown concern about issues surrounding safety and effectiveness (as a method of smoking cessation). A study of the available scientific evidence has concluded that the safety of the vapor or fumes inhaled by the users of these devices cannot be guaranteed. Contradictory results from various clinical trials and meta-analyses also mean that these devices cannot be recommended for their effectiveness in cessation, especi…
Post‐COVID ‐19 Liver Injury: Comprehensive Imaging With Multiparametric Ultrasound
2021
OBJECTIVES: This study aimed to define patterns of liver injury after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection using multiparametric ultrasound (mpUS) in a variable patient population with differing severities of COVID-19. METHODS: Ninety patients were enrolled into the study: 56 had SARS-CoV-2 3-9 months prior to enrolment; 34 served as a clinically healthy control group. All patients underwent an mpUS evaluation of the liver (elastography, dispersion and attenuation imaging). Seventy-six patients had abdominal magnetic resonance (MR) and noncontrast enhanced thoracic computed tomography (CT) scans performed at the same day. All patients were screened for bioc…
Vascular Adhesion Protein 1 Mediates Gut Microbial Flagellin-Induced Inflammation, Leukocyte Infiltration, and Hepatic Steatosis
2021
Toll-like receptor 5 ligand, flagellin, and vascular adhesion protein 1 (VAP-1) are involved in non-alcoholic fatty liver disease. This study aimed to determine whether VAP-1 mediates flagellin-induced hepatic fat accumulation. The effects of flagellin on adipocyte VAP-1 expression were first studied in vitro. Then, flagellin (100 ng/mouse) or saline was intraperitoneally injected into C57BL/6J (WT) and C57BL/6-Aoc3-/- (VAP-1 KO) mice on a high-fat diet twice a week every 2 weeks for 10 weeks. After that, the effects on inflammation, insulin signaling, and metabolism were studied in liver and adipose tissues. Hepatic fat was quantified histologically and biochemically. Because flagellin cha…

2021
Highlights • Urinary incontinence after delivery affects every fifth woman. • Urinary incontinence before pregnancy is a risk factor of postpartum incontinence. • Primiparous women are at a greater risk of urinary incontinence after birth.
