RESUMO

BACKGROUND: Invasive pneumococcal disease (IPD) remains a significant concern among children under 5, despite vaccination efforts. This study assessed IPD prevalence and associated risks in pediatric population. METHODS: An observational, retrospective, multicenter study in Comunidad Valenciana, Spain, of IPD cases in children under 13 from January 2012 to September 2022. Data from the CV Microbiology Surveillance Network (RedMIVA) and medical records were reviewed. RESULTS: A total of 379 IPD cases in 377 patients were analyzed, predominantly males (54.11 %) under 5 (81.17 %). PCV13 vaccination notably reduced PCV13-serotypes IPD (p=0.0002), except serotype 3. Pneumonia was common, with half having underlying conditions (50.40 %). Worse outcomes occurred in patients with neurological disorders (ANOVA, p=0.57). Vaccine failures often involved underlying conditions (63 %) and serotypes 3 and 19A. Immunodeficiencies may relate to recurrent IPD, but evidence is limited. CONCLUSION: Despite vaccination, IPD still impacts children, influenced by immunological status, affecting severity and mortality.

RESUMO

Respiratory syncytial virus (RSV) represents a high burden of disease in children and the primary cause of hospitalization, especially in children under 1 year old. In the Valencian Community (Spain), nirsevimab, a long-acting monoclonal antibody, was introduced for the RSV 2023-2024 season as a universal pre-exposure prophylaxis for high-risk children and those under 6 months old. This study examines its impact, coverage, and effectiveness. The campaign achieved 88.5 % coverage and 73.7 % of effectiveness. Analysis of over 27,000 susceptible children (over 24,000 immunized), showed that those immunized exhibited a threefold reduction in RSV incidence compared to non-immunized ones. To prevent one case, the number needed to immunize (NNI) was 63. Hospitalizations due to acute respiratory infections were almost two times lower in immunized children compared to non-immunized ones (0.9 % vs 1.6 %, respectively). These first results showcase the preliminary positive impact of this public health intervention.

RESUMO

OBJECTIVE: To analyse the profile of the persons and associations that participated in the course, quantify peer education activities and analyse their evolution. METHOD: A quantitative study using an analysis of the course records from 2009 to 2018 was designed for this purpose inside mihsalud program designed to promote health amongst persons in vulnerable situations in the city of Valencia (Spain). It offers a yearly training-action course of community health workers (CHW) that is attended by persons who have been proposed by associations. The associations were defined according to their population (immigrant, local or intercultural) and the CHWs according to gender, country of birth, year of course, association and continuity after training. Means and confidence intervals were calculated at 95% and a bivariate analysis was conducted in order to compare the activities that took place in 2009 to 2013 with those of 2014 to 2018. The time trends were analysed by applying linear regression models that included the different years studied as the dependent variable. RESULTS: 201 CHW of 31 nationalities were trained, 81.6% (95% confidence interval [95% CI]: 75.5-86.7] were women. Eighty-two associations participated, 51.2% (95% CI: 39.9-62.4] worked with culturally diverse populations. Participation by associations (p=.017) and CHWs (p=.377) increased in a statistically significant manner over the years. After the course, 35.3% (95% CI: 28.7-42.4] of the CHWs continued to collaborate voluntarily in the associations. CONCLUSIONS: The results of the CHW training-action course improve over time given that a significant increase in participation by associations and women can be seen, along with a greater number of activities completed during the training. One effect of this is that CHWs are contracted or carry out voluntary activities in the associations.
