Article Synopsis
  • A study conducted from 2017-2020 at five cardiac intensive care units (C-ICUs) found that influenza was detected in 5.5% of patients admitted during flu season, highlighting the potential for underdiagnosis.
  • Patients with influenza often had conditions like heart failure and required mechanical ventilation, with higher instances of myocarditis and pericarditis compared to those without influenza.
  • Despite a significant vaccination uptake (43% of patients), the findings suggest that routine screening for influenza is necessary at C-ICU admissions during influenza epidemics.

Background: The sanitary emergency created by the COVID-19 pandemic forced us to take exceptional measures that affect decision-making and administration of treatments with radiotherapy. The aim of the study was to analyze the impact of the COVID-19 pandemic on patients and professionals in a radiation oncology department.

Materials And Methods: We implement a plan with the objectives of maintaining radiotherapy treatment in those patients who need it and, at the same time, reducing the risk of spreading the virus to staff and patients.

Background: Evidence concerning the effectiveness of anti-cytomegalovirus immunoglobulin (CMVIg) following lung transplantation in the era of new antiviral agents is limited and controversial.

Material And Methods: At-risk patients (donor seropositive/recipient seronegative [D+/R-] and R+) received valganciclovir for 3 months (R+) or 6 months (D+/R). CMVIg (2 mg/kg) was given to D+/R- patients on days 1, 4, 8, 15, and 30 post-transplant, then monthly for a further year.

HSV-1 latently infects most humans, causing a variable clinical picture that depends, in part, on host genetic factors. Both IgG and its cellular FcRs, CD16A and CD32A-C (encoded by FCGR3A and FCGR2A-C, respectively, on chromosome 1), display polymorphisms that could affect their defensive function. Of potential relevance are a FCGR3A dimorphism resulting in CD16A-valine/phenylalanine-158 allotypes with different IgG affinity, variations conditioning NK cell expression of CD32B or CD32C, and IgG1 H chain (IGHG1) and kappa-chain (IGKC) polymorphisms determining allotypes designated G1m and Km.

Background: Flea-borne infections are distributed worldwide. Up to date there are no reports about microorganisms associated to fleas in Ecuador.

Methods: Seventy-one Pulex irritans and 8 Ctenocephalides felis fleas were removed from dogs in two Ecuadorian areas (Pastaza and Chimborazo Provinces) in December 2012.

Toxoplasmosis is a devastating opportunistic infection that can affect immunocompromised patients such as cord blood transplantation (CBT) recipients. The clinical characteristics of 4 toxoplasmosis CBT patients treated at our institution are reviewed, together with 5 cases collected from the literature. The rate of toxoplasmosis in our hospital was 6% in CBT recipients and 0.

HSV-1 establishes life-long latency that can result in clinical relapses or in asymptomatic virus shedding. Although virtually all adults have been exposed to HSV-1, the clinical course varies remarkably. Genetic host variability could be related to this clinical diversity.

The molecular epidemiology of HIV-1 is constantly changing, mainly as a result of human migratory flows and the high adaptive ability of the virus. In recent years, Spain has become one of Europe's main destinations for immigrants and one of the western European countries with the highest rates of HIV-positive patients. Using a phylogeographic approach, we have analyzed the relationship between HIV-1 variants detected in immigrant and native populations of the urban area of Madrid.

Herpes simplex virus type 1 (HSV-1) causes lifelong latent infections in most humans. Periodical virus reactivations from latency in the neurons of sensitive ganglia lead to transport to mucocutaneous regions and productive replication, which results in recurrent inflammatory herpetic lesions or in asymptomatic virus shedding. The medical consequences of such lesions and the frequency of recurrences vary greatly in different subjects.

Background: To know the prevalence of HCV infection in patients diagnosed with B-NHL in our area.

Patients And Method: A group of patients diagnosed with B-NHL between 1998-99 were carefully reviewed (serological tests, HCV RNA, laboratory studies, toxicity, response to treatment and evolution) in a transversal study.

Results: Overall 9/77 (11.

Sudden deafness constitutes a challenge in terms of the etiopathogenic diagnosis. The causative origin of sudden deafness usually remains unknown. However, available evidence suggests that viral and Mycoplasma pneumoniae infection could be one factor involved.

Bacterial translocation appears to be an important mechanism in the pathogenesis of spontaneous infections in cirrhosis. Cirrhotic patients are commonly treated with beta-adrenoceptor blockers, but the impact of this treatment in the factors promoting bacterial translocation has not been investigated. This study was aimed at investigating in cirrhotic rats with ascites the effect of propranolol on intestinal bacterial load, transit, and permeability of the bowel and on the rate of bacterial translocation.

Objective: Most patients who developed visceral leishmaniasis (VL) in our country are ímmunocompromised (IC) host, frequently HIV-infected patients. One objective was to know if there were differences about the clinical manifestations, diagnostic tests or prognosis in IC patients who were infected or not with HIV (HIV+ and HIV-, respectively). Also we wonder if some features were associated with death during the initial episodes of VL.
