TV-based assistive integrated service to support European adults living with mild dementia or mild cognitive impairment (TV-AssistDem): study protocol for a multicentre randomized controlled trial.

Background: Mild cognitive impairment and mild dementia progressively compromise the ability of people to live independently and can have a negative impact on their quality of life. Within the current European Active and Assisted Living programme (AAL), project TV-AssistDem has been developed to deliver a TV-based platform service to support patients with mild cognitive impairment or mild dementia and provide relief to their caregivers. The application is intended to be used daily at home, mainly by the participants themselves, with the help of their informal caregivers.

Evaluation of proadrenomedullin as a diagnostic or prognostic biomarker of acute appendicitis in children.

Introduction: A delay in the diagnosis of acute appendicitis (AA), with the added complication of symptoms that mimic other self-limited causes of abdominal pain, can lead to an increase in ruptured appendices and morbimortality. None of the serum biomarkers evaluated to date have shown a predictive value for early diagnosis.

Objective: The objective of this study was to evaluate the usefulness of proadrenomedullin (MR-proADM) in the diagnosis of AA in children presenting with acute abdominal pain.

Mycobacterial disease in patients with chronic granulomatous disease: A retrospective analysis of 71 cases.

Background: Chronic granulomatous disease (CGD) is a rare primary immunodeficiency caused by inborn errors of the phagocyte nicotinamide adenine dinucleotide phosphate oxidase complex. From the first year of life onward, most affected patients display multiple, severe, and recurrent infections caused by bacteria and fungi. Mycobacterial infections have also been reported in some patients.

Diagnostic accuracy and prognostic utility of D Dimer in acute appendicitis in children.

Unlabelled: The objective was to determine the uselfulness of D Dimer (DD) as a diagnostic or prognostic marker in acute appendicitis (AA) in children using a prospective observational study in the pediatric emergency department of a tertiary hospital. We enrolled 135 patients aged 1-16 years presenting with abdominal pain consistent with AA, who required laboratory studies. We analyzed clinical, analytical variables and histopathology findings (when they underwent surgery).

Boosting with mycobacterial heparin-binding haemagglutinin enhances protection of Mycobacterium bovis BCG-vaccinated newborn mice against M. tuberculosis.

Heterologous prime-boost regimens are a valuable strategy to improve the generation of effector-memory T cell responses against intracellular pathogens. In this study we show that newborn mice vaccinated with bacillus Calmette-Guérin (BCG) and boosted with heparin-binding haemagglutinin (HBHA) had enhanced protective immunity against intranasal or aerosol Mycobacterium tuberculosis challenge over non-boosted mice, as evidenced by a considerable reduction of mycobacterial load in spleen and lung. The route of HBHA delivery had a differential impact on cytokine and antibody production in BCG-primed mice.

The coiled-coil N-terminal domain of the heparin-binding haemagglutinin is required for the humoral and cellular immune responses in mice.

Heparin-binding haemagglutinin (HBHA) is a 28-kDa mycobacterial adhesin, composed of three functional domains. Previous work has shown that the C-terminal methylated domain is important for adherence, and it is involved in protective T cell immunity in mouse models. However, the role of the coiled-coil N-terminal domain of HBHA in its overall immunogenic capacity remains elusive.

Structural implication of the induced immune response by Bacillus thuringiensis Cry proteins: role of the N-terminal region.

The potential role of the regions (carboxil and amino) of the Cry proteins in the ability of these proteins to elicit strong immune responses was investigated. Intraperitoneal immunization of mice with the homologous Cry1A protoxins (130-133 kDa), with the long C-terminal half gave rise mostly to similar, strong serum and mucosal IgG and IgM antibody response but a lower induction of these Ab by intranasal route. Remarkably, Cry3A protoxin, devoid of C-terminal half was able to induce a significant mucosal IgG, and IgM Ab as well as Cry1A protoxins, suggesting us that immunogenic abilities are not restricted to C-terminal half but N-terminal half itself could be involved.
