Background: Over time, vaccination has been consolidated as one of the most cost effective and successful public health interventions and a right of every human being. This study aimed to assess the spatial dynamics of the vaccine coverage (VC) rate of children aged < 1 year per municipality in the Brazilian Northeast at 2016 and 2017. Methods: This is a mixed-type ecological study that use a Public domain data Health Information. Vaccine doses were obtained from the Information System of the Brazilian National Immunization Program, and live births from the Brazilian Information System of Live Births of the Brazilian Unified Health System. Descriptive analysis of the coverage of all the vaccines for each year of the study was conducted, and Mann–Whitney U test was used to compare VC between the study years. Chi-squared test was used to evaluate the association between the years and VC, which was stratified into four ranges, very low, low, adequate, and high. Spatial distribution was analyzed according to both each study year and vaccine and presented as thematic maps. Spatial autocorrelation was analyzed using Moran’s Global and Local statistics. Results: Compared with 2017, 2016 showed better VC (p < 0.05), except for Bacillus Calmette–Guérin. In the spatial analysis of the studied vaccines, the Global Moran’s Index did not show any spatial autocorrelation (p > 0.05), but the Local Moran’s Index showed some municipalities, particularly the Sertão Paraibano region, with high VC, high similarity, and a positive influence on neighboring municipalities (p < 0.05). In contrast, most municipalities with low VC were concentrated in the Mata Paraibano region, negatively influencing their neighbors (p < 0.05). Conclusion: Uneven geographic regions and clusters of low VC for children aged < 1 year in the State of Paraíba were spatially visualized. Health policy makers and planners need to urgently devise and coordinate an action plan directed at each state’s regions to fulfill the vaccination calendar, thereby reversing the vulnerability of this age group, which is at a higher risk of diseases preventable by vaccination.

This study sought to verify the effects of acupuncture as an adjuvant treatment for the control of asthma. This was a randomized, controlled, crossover trial conducted at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A total of 74 patients with mild/moderate, persistent asthma were randomized into two therapeutic groups: Group A - 31 patients underwent 10 real weekly acupuncture sessions, followed by a 3-week washout period and 10 sham weekly acupuncture sessions; and Group B - 43 patients underwent 10 sham weekly acupuncture sessions, followed by a 3-week washout period and 10 real weekly acupuncture sessions. Patients used short- and long-acting β-2 agonists and inhaled corticosteroids when necessary. Prior to treatment and after each period of 10 treatment sessions, the patients were evaluated for spirometry, induced sputum cell count, exhaled nitric oxide (NO) and with the Short Form 36 (SF-36) and Questionnaire on Quality of Life-Asthma (QQLA) questionnaires. Daily peak flow and symptom diaries were registered. The level of significance adopted was 5% (α=0.05). In Group B, after real acupuncture, there was a decrease in eosinophils (p=0.035) and neutrophils (p=0.047), an increase in macrophages (p=0.001) and an improvement in peak flow (p=0.01). After sham acupuncture treatment, patients experienced less coughing (p=0.037), wheezing (p=0.013) and dyspnea (p=0.014); similarly, after real acupuncture, patients reported less coughing (p=0.040), wheezing (p=0.012), dyspnea (p<0.001) and nocturnal awakening episodes (p=0.009). In Group A, there was less use of rescue medication (p=0.043). After the sham procedure, patients in Group A experienced less coughing (p=0.007), wheezing (p=0.037), dyspnea (p<0.001) and use of rescue medication (p<0.001) and after real acupuncture, these patients showed improvements in functional capacity (p=0.004), physical aspects (p=0.002), general health status (p<0.001) and vitality (p=0.019). Sham acupuncture also led to significant differences in symptoms, but these were not different from those seen with real acupuncture. Spirometry and exhaled NO levels did not show a difference between sham and real acupuncture treatment. In addition, no significant difference was demonstrated between treatments regarding the quality of life evaluation. Real and sham acupuncture have different effects and outcomes on asthma control. The crossover approach was not effective in this study because both interventions led to improvement of asthma symptoms, quality of life and inflammatory cell counts. Thus, sham acupuncture cannot serve as a placebo in trials with acupuncture as the main intervention for asthma.

Leprosy and tuberculosis are endemic in several countries. The aim of this study was to describe factors associated with co-infection among both diseases. A systematic review was carried out, following the Quality of Reporting of Meta-analyses, with the PubMed and Biblioteca Virtual em Saúde (BVS) portals as sources, under eligibility criteria: cross-sectional, cohort, case-control studies or case reports, published in Portuguese, English, French and Spanish, from 2015 to 2020. Studies that dealt with leprosy and tuberculosis not in the context of co-infection were excluded. The initial phase resulted in 1079 articles; 13 went on to a final stage. All were case reports. Thirteen (72.2%) participants were male, aged between 17 and 72 years. Life habits were found in 8 (44.4%) of the articles: 1 (12.5%) reported chronic alcoholism, 1 (12.5%) reported chronic smoking and alcoholism and 1(12.5%) reported chronic smoking, alcoholism and use of illicit drugs. Pathological history was mentioned by 14 (77.8%) patients; 1 (7.1%) reported HIV/AIDS. Three patients (16.6%) described previous history of tuberculosis and/or leprosy. Seven (38.9%) participants reported vaccination with Bacillus Calmette-Guérin. The pulmonary form of tuberculosis predominated and one third of the patients presented resistance to, at least, one tuberculostatic. All cases had multibacillary leprosy. The study did not highlight any comorbidity, and there was no change in the course of the conditions owing to co-infection.

Measles is a contagious viral disease that seriously affects children. The measles vaccine is widely recommended in Brazil and in the world; however, the disease remains relevant for the health authorities. The aim of the present study was to evaluate first and second dose of measles vaccine coverage (VC) in the cities of São Paulo and its spatial dynamics between 2015 and 2020. Method: In this mixed-type ecological study, we used secondary, public domain data from 2015 to 2020, extracted from the Digital Information System of the National Immunization Program, Mortality Information System and the National Live Birth Information System. After calculating the VC, the following four categories were created: very low, low, adequate, and high, and the spatial autocorrelation of VC was analyzed using the Global and Local Moran’s statistics. A steady decline in adherence to the vaccination was observed, which dynamically worsened until 2020, with a high number of cities fitting the classification of ineffective coverage and being potentially harmful to the effectiveness of the immunization activities of their neighbors. A direct neighborhood pattern was observed between the units with low vaccination coverage, which implied that the reduction in measles VC was somehow related to and negatively influenced by the geographic location and social culture of these areas.
