Persistence of hepatitis E virus in the liver of non-viremic naturally infected wild boar.

Hepatitis E virus (HEV) is an emerging zoonotic pathogen with pigs and wild boar serving as reservoirs for human infection through direct contact with infected animals or the consumption of raw or undercooked pork products. The liver is considered the main target site of HEV replication in swine and an important organ in the pathogenesis of the disease. The aim of this study was to characterize the target liver cells for HEV entry in naturally infected wild boar and to evaluate the type and severity of the pathological changes in order to reach a better understanding of the hepatic pathogenic mechanisms involved in hepatitis E.

Monitoring of Schmallenberg virus in Spanish wild artiodactyls, 2006-2015.

Schmallenberg disease is an emerging disease that affects domestic and wild ruminants in Europe. An epidemiological survey was carried out to assess exposure to Schmallenberg virus (SBV) in wild artiodactyls in Spain between 2006 and 2015. A total of 1751 sera from wild artiodactyls, including 1066 red deer, 304 fallow deer, 192 mouflon, 109 wild boar, 49 roe deer and 31 Spanish ibex were tested for antibodies against SBV by ELISA and confirmed by virus neutralization test.

Spontaneous clearance of chronic hepatitis C is rare in HIV-infected patients after effective use of combination antiretroviral therapy.

Objective: To evaluate the rate of spontaneous resolution of chronic hepatitis C (CHC) infection in a cohort of HIV-infected patients.

Methods: A retrospective analysis of 509 HIV-infected patients with chronic HCV infection was performed at two reference hospitals in Andalusia. The main variable of the study was spontaneous clearance of CHC, defined as a negative HCV RNA result after at least two previous quantitative measurements of HCV RNA separated by a minimum of 12 months.

Impact of universal access to hepatitis C therapy on HIV-infected patients: implementation of the Spanish national hepatitis C strategy.

In April 2015, the Spanish National Health System (SNHS) developed a national strategic plan for the diagnosis, treatment, and management of hepatitis C virus (HCV). Our aim was to analyze the impact of this on human immunodeficiency virus (HIV)-infected patients included in the HERACLES cohort during the first 6 months of its implementation. The HERACLES cohort (NCT02511496) was set up in March 2015 to evaluate the status and follow-up of chronic HCV infection in patients co-infected with HIV in the south of Spain.

Lipopolysaccharide Binding Protein and Oxidative Stress in a Multiple Sclerosis Model.

Recent findings in experimental autoimmune encephalomyelitis (EAE) suggest that altering certain bacterial populations present in the gut may lead to a proinflammatory condition, that could result in the development of multiple sclerosis (MS). Also, Reactive Oxygen Species seem to be involved in the course of MS. In this study, it has been aimed to relate all these variables starting from an analysis of the lipopolysaccharide (LPS) and LPS-binding protein (LBP) with the determination of parameters related to oxidative stress in the blood, brain and spinal cord.

Prognostic significance of performing universal HER2 testing in cases of advanced gastric cancer.

Background: Trastuzumab significantly improves overall survival (OS) when added to cisplatin and fluoropyrimidine as a treatment for HER2-positive advanced gastric cancers (AGC). The aim of this study was to evaluate the impact of the gradual implementation of HER2 testing on patient prognosis in a national registry of AGC.

Methods: This Spanish National Cancer Registry includes cases who were consecutively recruited at 28 centers from January 2008 to January 2016.

Current views on interferon therapy for HIV.

Introduction: Knowledge of IFN-antiviral activity against HIV infection dates from the first years of the AIDS epidemic. Recombinant IFN had an inhibitory effect on HIV and was not toxic to peripheral blood mononuclear cells (PBMC), and this finding was the basis for the design of clinical trials that evaluated the potential role of IFN-alpha as an inhibitor of HIV replication.

Areas Covered: This review summarizes the history of IFN-alpha in the treatment of HIV infection with reviews of studies performed in different clinical settings; in the pre-highly active antiretroviral therapy (HAART) era, as part of a structured treatment interruption (STI) strategy, in acute HIV infection, as part of salvage therapy, and eliminating the HIV reservoir.

[Utility of biomarkers in abdominal pain management].

Abdominal pain conditions that fall into the category of acute abdomen (AA) are the most important ones to identify quickly. Diagnostic delay can lead to death or significant complications. Biological markers have the potential to improve the diagnostic and prognostic capacity of clinical assessment and the conventional complement of tests.

SEOM guidelines for cervical cancer.

Cervical cancer (CC) is the second most common cancer worldwide, strongly linked to high-risk human papilloma virus infection. Although screening programs have led to a relevant reduction in the incidence and mortality due to CC in developed countries, it is still an important cause of mortality in undeveloped countries. Clinical stage is still the most relevant prognostic factor.
