ABSTRACT
Orally administered probiotic micro-organisms are able to regulate the exacerbated immune response during the antigenic sensitisation process. The aim of the present study was to evaluate the potential efficacy of probiotic fermented milk (PFM) in preventing or treating allergy in an experimental model, and to investigate its underlying mechanisms. Ovoalbumin (OVA)-sensitised BALB/c mice were fed with PFM before the sensitisation procedure or fed continuously with PFM. At 7 and 15 d post-sensitisation, anti-OVA-specific IgE, IgG, IgG1 and IgG2a concentrations were measured in the serum and broncho-alveolar lavage fluid (BALF). Concentrations of interferon-γ (IFN-γ), IL-4, IL-10 and total secretory IgA (S-IgA) were measured in the supernatants of macerated lungs or in the BALF. The levels of IgA+, CD4+ and CD8+ T lymphocytes and F4/80+ cells were measured in the lungs by immunofluorescence. Inducible CD4+/CD25/Foxp3+ regulatory T (Treg) cells were evaluated in the lungs. PFM shifted the T helper (Th)2 profile response towards a Th1 response that led to the production of IgG instead of IgE, with increasing levels of IL-10 and IFN-γ that play an important role in immunomodulation exerted by PFM administration in sensitised mice. Anti-OVA-specific IgE levels were significantly decreased; however, there was no modification in the levels of anti-OVA-specific IgG and total S-IgA. PFM did not influence Treg cells in treated mice. Consumption of PFM could be a promising strategy in the amelioration of airway allergies, considering that the effect is mediated by the production of IgG through the activation of Th1 instead of the direct activation of Th2 cells to produce IgE.

Dado los escasos antecedentes de estudios sobre los sistemas de investigación para la salud en Argentina, el Ministerio de Salud de la Nación decidió realizar un diagnóstico de las actividades de investigación en el subsector público de salud. OBJETIVO: Describir las actividades de gestión, producción y difusión de la investigación realizadas por los ministerios de Salud y sus organismos dependientes entre 2010 y 2012. MÉTODOS: Estudio descriptivo transversal. Se estudiaron 20 ministerios (Nación, Ciudad Autónoma de Buenos Aires y provincias de Buenos Aires, Córdoba, Chaco, Corrientes, Chubut, Formosa, Jujuy, La Pampa, La Rioja, Mendoza, Misiones, Neuquén, Río Negro, San Juan, Santa Cruz, Santiago del Estero, Tierra del Fuego y Tucumán). Se efectuó una encuesta estructurada a funcionarios responsables de organismos ministeriales de nivel central, descentralizados y servicios de salud. RESULTADOS: Se relevaron 299 organismos y 1.070 investigaciones; el 80% de las cuales se había realizado en servicios de salud. El 61,3% del total recibió financiamiento. CONCLUSIONES: La magnitud de las investigaciones halladas en este estudio evidencia la importancia que las actividades de investigación tienen en los ministerios de Salud estudiados, en consonancia con el apoyo que se le ha dado en los últimos años a esta actividad como política de Estado...

OBJECTIVE: To study the association between vital exhaustion, anxiety and anger with acute coronary event; second, determine whether they are associated with each other, and third, if the joint interaction of two or more factors increases the risk for coronary event. METHOD: We conducted a case-control study with 165 patients, both sexes, between 35 and 75 years, 90 patients with acute ischemic coronary event and 75 controls hospitalized with an acute event of non-ischemic cardiac causes. RESULTS: Statistically significant differences between the control group and the ischemic coronary group for vital exhaustion was found (OR = 3.0 (1.6-5.5) p < 0.001 (chi2)). Psychosocial risk factors are associated each with p < 0.001: anxiety and vital exhaustion (Spearman Rho = 0.58), anger and vital exhaustion (Spearman Rho = 0.41) and anxiety and anger (Spearman Rho = 0.38). The simultaneous presence of vital exhaustion and anxiety increases the probability of an acute ischemic coronary event (p < 0.01). CONCLUSIONS: In this study we found a significative association between vital exhaustion and acute ischemic coronary event, psychosocial risk factors are associated with each other and simultaneous presence of vital exhaustion and anxiety increases the probability of an acute ischemic coronary event.

Beneficial effects of prebiotics like inulin and fructo-oligosaccharides (FOS) have been proven in health and nutrition. Yacon (Smallanthus sonchifolius), an Andean crop, contains FOS (5070% of its dry weight) and, therefore, is considered a prebiotic. Commercial FOS can upregulate total secretory IgA (S-IgA) in infant mice, prevent infection with Salmonella in swine or enhance immune response for Salmonella vaccine in a mouse model. Previously, we found that administration of yacon root flour regulates gut microbiota balance and has immunomodulatory effects without inflammatory responses. The aim of the present paper is to analyse if yacon prevents enteric infection caused by a strain of Salmonella enteritidis serovar Typhimurium (S. Typhimurium) in a mouse model. BALB/c mice were supplemented with yacon flour (45 d), challenged with S. Typhimurium and killed to study pathogen translocation, total and specific IgA production by ELISA, presence of IgA and other cytokines and Toll-like receptor 4 (TLR4) and clustor of differentiation 206 (CD206) receptors positive cells by immunofluorescence and histological changes. Yacon flour administration had a protective effect from 15 to 30 d of treatment. We found a peak of total S-IgA production without translocation of the pathogen for these periods. At 30 d, there was an increase in IL-6 and macrophage inflammatory proteins-1aþ cells and expression of the receptors CD206 and TLR4. Yacon flour did not have incidence in pathogen-specific S-IgA production. Longer periods (45 d) of administration had no protective effect. Therefore, yacon can prevent enteric infection caused by S. Typhimurium when given up to 30 d; this effect would be mediated by enhancing non-specific immunity, such as total S-IgA, that improves the immunological intestinal barrier.

OBJECTIVE: To determine the strength of the association between the Vital exhaustion syndrome (VES) and acute coronary ischemic events in hospitalized Argentinean sample. METHODS: VES was measured in 180 patients of both sexes, 90 admitted due to an acute coronary ischemic syndrome (AMI or unstable angina) and a control group of 90 admitted due to an acute non-coronary cardiac event. VES was evaluated with the Maastricht questionnaire during the first week of hospitalization. RESULTS: Dividing the sample in two categories: exhausted and non-exhausted, 57 (63,33%) of the coronary were exhausted, while among the non coronary group, 33 were exhausted (36,66%)(OR=3.1 (1.7-5.8)). The exhaustion score was: control mean score: 17,1 (sd 8,96); case mean score: 21,1 (sd10,60) p: 0.006. Dislipemia was another factor with a significant difference: control 27 (30%) case 44 (62%) OR= 2.2 (1.2-4.1) p=0.01. Logistic regression was performed, including an interaction model between DLP and exhaustion, and it did not show a significant effect. CONCLUSIONS: Our results indicate that in Argentina, among other countries as reported in the literature, VES is a psychological condition that is strongly and independent associated to acute coronary events.
