title: Inequalities in oral health: are schoolchildren receiving the Bolsa Família more vulnerable?

description: OBJECTIVE : To evaluate the association between being a recipient of the Bolsa Família program and oral health conditions in Brazilian schoolchildren. METHODS : A cross-sectional study was conducted with 1,107 schoolchildren aged between eight and 12 years from 20 public and private schools in Pelotas, RS, Southern Brazil. A list of all children receiving the Bolsa Família program was provided by the participant schools. Demographic, socioeconomic and oral hygiene information were assessed using a questionnaire completed by the schoolchildren and their parents. Dental exams were performed to assess the presence of dental plaque and prevalence of dental caries. Data were analyzed by Chi-square test, Chi-square test for linear trend and multivariate Poisson Regression (prevalence ratio; 95% confidence interval). RESULTS : Schoolchildren from non-nuclear families, with a DMFT ≥ 1 and who had never visited a dentist were associated with receiving the Bolsa Família. Final model showed that caries prevalence was twice as high (PR 2.00; 95%CI 1.47;2.69) in schoolchildren benefiting from the Bolsa Família . It was also showed that schoolchildren benefiting from the program presented greater severity of dental caries compared to school children from private schools (RR 1.53; 95%CI 1.18;2.00). After final adjustments, the prevalence of schoolchildren who have never visited a dentist was six times higher in children who received the government benefit (PR 6.18; 95%CI 3.07;12.45) compared to those from private schools. CONCLUSIONS : Schoolchildren benefiting from the Bolsa Família program experienced more caries lesions and have less frequently accessed dental care services, which suggest the need to include oral health in the program.

title: Correcting vital information: estimating infant mortality, Brazil, 2000-2009

description: OBJECTIVE : To propose a simplified method of correcting vital information and estimating the coefficient of infant mortality in Brazil. METHODS : Vital data in the information systems on mortality and live births were corrected using correction factors, estimated based on events not reported to the Brazilian Ministry of Health and obtained by active search. This simplified method for correcting vital information for the period 2000-2009 for Brazil and its federal units establishes the level of adequacy of information on deaths and live births by calculating the overall coefficient of mortality standardized by age and the ratio between reported and expected live births, respectively, in each Brazilian municipality. By applying correction factors to the number of deaths and live births reported in each county, the vital statistics were corrected, making it possible to estimate the coefficient of infant mortality. RESULTS : The highest correction factors were related to infant deaths, reaching values higher than 7 for municipalities with very precarious mortality information. For deaths and live births, the correction factors exhibit a decreasing gradient as indicators of adequacy of the vital information improve. For the year 2008, the vital information corrected by the simplified method per state were similar to those obtained in the research of active search. Both the birth rate and the infant mortality rate decreased in the period in all Brazilian regions. In the Northeast, the annual rate of decline was 6.0%, the highest in Brazil (4.7%). CONCLUSIONS : The active search of deaths and births allowed correction factors to be calculated by level of adequacy of mortality information and live births. The simplified method proposed here allowed vital information to be corrected per state for the period 2000-2009 and the progress of the coefficient of infant mortality in Brazil, its regions and states to be assessed.

title: Exploratory study of air quality in elementary schools, Coimbra, Portugal

description: OBJECTIVE : To analyze the air quality in elementary schools and their structural and functional conditions. METHODS : Air quality in 51 elementary schools (81 classrooms) in the city of Coimbra, Portugal, both inside and outside of the rooms was evaluated during the four seasons, from 2010 to 2011. Temperature (T°), relative humidity (Hr), concentrations of carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), compounds were evaluated, as were volatile organics (VOC), formaldehyde and particulate matter (PM10), from November 2010 to February 2011 (autumn/winter) and March 2011 to June 2011 (spring/summer). A grid characterizing the structural and functional conditions of the schools was created. The statistical Student t test for paired samples and the Wilcoxon t test were applied. RESULTS : In 47 schools, the average CO2concentrations were above the maximum reference concentration (984 ppm) mentioned in Portuguese legislation. The maximum concentration values found inside the rooms were critical, especially in the fall/winter (5,320 ppm). In some schools the average concentrations of VOC and PM10within the maximum concentration exceeded the reference legislated. The values (risk) of CO, formaldehyde, NO2, SO2and O3detected were not relevant. CONCLUSIONS : There was a higher concentration of pollutants inside the rooms compared with outside. Inadequate ventilation is associated with high CO2concentration in the classroom.

title: Access to medicines for acute illness in middle income countries in Central America

description: OBJECTIVE : To analyze the main predictors of access to medicines for persons who experienced acute health conditions. METHODS : This was a cross-sectional analytic study, based on data from household surveys. We examined the predictors of: (1) seeking care for acute illness in the formal health care system and (2) obtaining all medicines sought for the acute condition. RESULTS : The significant predictors of seeking health care for acute illnesses were urban geographic location, head of household with secondary school education or above, age under 15, severity of illness perceived by the respondent, and having health insurance. The most important predictor of obtaining full access to medicines was seeking care in the formal health care system. People who sought care in the formal system were three times more likely to receive all the medicines sought (OR 3.0, 95%CI 2.3;4.0). For those who sought care in the formal health system, the strongest predictors of full access to medicines were seeking care in the private sector, having secondary school education or above, and positive perceptions of quality of health care and medicines in public sector health facilities. For patients who did not seek care in the formal health system, full access to medicines was more likely in Honduras or Nicaragua than in Guatemala. Urban geographic location, higher economic status, and male gender were also significant predictors. CONCLUSIONS : A substantial part of the population in these three countries sought and obtained medicines outside of the formal health care system, which may compromise quality of care and pose a risk to patients. Determinants of full access to medicines inside and outside the formal health care system differ, and thus may require different strategies to improve access to medicines.

title: Pictorial health warnings on cigarette packs and the impact on women

description: OBJECTIVE : To analyze the association between the pictorial graphic health warnings on cigarette packs and their impact on intention to quit smoking among women. METHODS : Population-based cross-sectional study among 265 women daily smokers in the State of Paraná in 2010. The sample size was calculated using cluster sampling. Participants were asked whether they had seen any pictorial graphic health warnings in the past 30 days, whether these warnings made them think about quitting, and intensity of these thoughts. The data was analyzed using logistic regression and the independent variables included age, educational attainment, whether they had children, whether they had attempted to quit smoking in the past 12 months, age of smoking initiation, number of cigarettes smoked per day, their town of residence, and how soon after waking do they smoke their first cigarette. RESULTS : Participants (91.7%) reported seeing the pictorial graphic health warnings in the past 30 days. Women with elementary education or below and women with some/complete high school education were more likely to think about quitting smoking after seeing the pictorial graphic health warningsthan women with higher education (OR = 4.85; p = 0.0028 and OR = 2.91; p = 0.05), respectively). Women who attempted to quit smoking in the past 12 months were more likely to think about quitting than women who had not (OR = 2.49; p = 0.001). Quit attempts within the last 12 months were associated with intensity of these thoughts (OR = 2.2; p = 0.03). CONCLUSIONS : Results show an association between pictorial graphic health warnings and intent to quit smoking among women with warnings having a greater impact among women with less education and who had attempted to quit smoking within the past year. Tobacco control strategies should be implemented across all groups of women regardless of their educational attainment.

title: Implementation of the Brazilian Breastfeeding Network and prevalence of exclusive breastfeeding

description: OBJECTIVE : To evaluate the association between the level of implementation of the Brazilian Breastfeeding Network and the prevalence of exclusive breastfeeding. METHODS : Cross-sectional study of a representative sample of 916 infants &lt; 6 months, in Ribeirao Preto, SP, Southeastern Brazil, in 2011. Data on breastfeeding, place of outpatient care and other characteristics were collected during the National Vaccination Campaign. The factor studied is where outpatient care took place: Private; Non-Network Public; Public with Network Workshop; and Public certified by Network. The individualized effect of the factor studied on the outcome was analyzed using Poisson regression with robust variance. RESULTS : The comparison between private (reference category) and other outpatient care showed significant dose-response relationship with a progressive increase in the prevalence of exclusive breastfeeding in public non-Network, public with Network Workshop and public accredited by Network outpatient care (p = 0.047). As regards the Basic Health Units accredited by Network category, the Prevalence Ratio of exclusive breastfeeding was equal to 1.47 (95%CI 1.00;2.17), after adjustment for confounding variables. CONCLUSIONS : The prevalence of exclusive breastfeeding for infants &lt; 6 months was higher in places accredited by the Brazilian Breastfeeding Network, which evinces the importance of investing in accreditation of Basic Units of Health by this strategy.

title: Hybridization capture sequencing data

description: The data were generated as part of a methodological comparison of nine different taxonomic classes (Demospongiae, Gastropoda, Polychaeta, Malacostraca, Insecta, Actinopterygii, Chondrichthyes, Amphibia, and Reptilia). An attempt was made to obtain the desired genetic target region from all 37 samples using hybridization capture with an RNA bait set. The samples are up to 200-year-old museum samples, some of which were fixed in formalin. The DNA was according to Dabney et al. (2013) using a GuSCN based extraction buffer (Rohland et al. 2004) and treatments as in Straube, Lyra et al. (2021) and a DNA library according to Gansauge et al. (2017) created. The libraries were mainly built according to the protocol of Huang et al. Captured in 2021 and then sequenced on an Illumina Nextseq 500 sequencing platform, using 500/550 High Output v2.5 (75 cycles, Illumina 20024906) kits (75 bp single-end reads).
