Política Nacional de Saúde Bucal: fatores associados à integralidade do cuidado

OBJETIVO: Analisar fatores relacionados à integralidade na assistência à saúde bucal em centros de especialidades odontológicas segundo os princípios norteadores da Política Nacional de Saúde Bucal. MÉTODOS: Estudo exploratório transversal baseado em entrevista com 611 usuários de quatro centros de especialidades odontológicas da Bahia em 2008. A variável dependente foi descrita como "integralidade na saúde bucal", correspondente à realização de tratamento odontológico básico antes do tratamento especializado ou concomitante a este. As principais co-variáveis se referiram a cobertura da estratégia saúde da família no município, características sociodemográficas dos usuários, acessibilidade organizacional e geográfica ao serviço, além do tipo de especialidade demandada. RESULTADOS: Residentes de cidades em que o Programa Saúde da Família tinha cobertura >; 50% tiveram mais chance de concluir o tratamento odontológico (RP = 2,03, IC 95%: 1,33;3,09) em relação àqueles residentes em locais com cobertura menor. Quem buscou tratamento endodôntico teve mais chance de receber assistência integral à saúde bucal do que os usuários em busca de outras especialidades (RP = 2,31, IC 95%: 1,67;3,19). Os usuários com maior facilidade no acesso geográfico ao serviço especializado (RP = 1,22, IC 95%: 1,03;1,41), com ficha de referência (RP = 2,95, IC 95%: 1,82;4,78) e oriundos da atenção primária (RP = 3,13, IC 95%: 1,70;5,77) tiveram mais chance de alcançar a integralidade na assistência à saúde bucal em relação aos demais usuários. CONCLUSÕES: Usuários com facilidade de acesso geográfico, mais jovens e necessidade de serviço endodôntico tiveram mais chance de receber assistência integral. A implantação de centros de especialidades odontológicas em municípios nos quais a atenção primária à saúde não esteja adequadamente estruturada não é recomendada, visto que a atenção secundária estaria atendendo a livre demanda e executando procedimentos básicos e, portanto, não cumprindo o princípio da integralidade pretendida.OBJETIVO: Analizar factores relacionados a la integración en la asistencia a la salud bucal en centros de especialidades odontológicas según los principios que guían la Política Nacional de Salud Bucal. MÉTODOS: Estudio exploratorio transversal basado en entrevista con 611 usuarios de cuatro centros de especialidades odontológicas de Bahia, Noreste de Brasil, en 2008. La variable dependiente fue descrita como "integración en la salud bucal", correspondiente a la realización de tratamiento odontológico básico antes del tratamiento especializado o concomitante a este. Las principales covariables se refirieron a cobertura de la estrategia salud de la familia en el municipio, características sociodemográficas de los usuarios, accesibilidad organizacional y geográfica al servicio, además del tipo de especialidad demandada. RESULTADOS: Residentes de ciudades donde el Programa Salud de la Familia tenía cobertura >;50% tuvieron más chance de concluir el tratamiento odontológico (RP=2,03, IC 95%: 1,33;3,09) con relación a aquellas que estaban residenciados en localidades con cobertura menor. Quien buscó tratamiento endodóntico tuvo más chance de recibir asistencia integral a la salud bucal en comparación con los usuarios que buscan otras especialidades (RP=2,31, IC 95%: 1,67;3,19). Los usuarios con mayor facilidad en el acceso geográfico al servicio especializado (RP=1,22, IC 95%: 1,03;1,41), con ficha de referencia (RP=2,95, IC 95%: 1,82;4,78) y oriundos de la atención primaria (RP=3,13, IC 95%: 1,70;5,77) tuvieron más chance de alcanzar la integración en la asistencia a la salud bucal con relación a los demás usuarios. CONCLUSIONES: Usuarios con facilidad de acceso geográfico, más jóvenes y necesidad de servicios endodóntico tuvieron más chance de recibir asistencia integral. La implantación de centros de especialidades odontológicas en municipios donde la atención primaria a la salud no se encuentre adecuadamente estructurada no es recomendada, visto que la atención secundaria estaría atendiendo la libre demanda y ejecutando procedimientos básicos y, por lo tanto, no cumpliendo el principio de la integración pretendida.OBJECTIVE: To analyze the factors associated with comprehensiveness in oral health care in Centers of Dental Specialists, according to the guiding principles of the Brazilian Oral Health Policy. METHODS: An exploratory cross-sectional study, based on an interview with 611 users of four specialized dental care centers, was performed in the state of Bahia, Northeastern Brazil, in 2008. The dependent variable was described as "comprehensiveness in oral health care", corresponding to having a primary dental care performed before specialized treatment or concomitantly with it. The main covariables referred to the level of coverage of the family health strategy in the city, users' sociodemographic characteristics, and organizational and geographic accessibility to the service, in addition to the type of specialized care required. RESULTS: Residents of the cities where the Family Healthcare Program had a coverage >;50% were more likely to conclude their dental treatment (PR=2.03, 95% CI: 1.33;3.09), compared to those who lived in places with lower coverage. Individuals who sought endodontic treatment were more likely to receive comprehensive oral health care than users who were seeking other types of specialized care (PR=2.31, 95% CI: 1.67;3.19). Users with better geographic accessibility to specialized services (PR=1.22, 95% CI: 1.03;1.41), with a reference guide from primary care (PR=2.95, 95% CI: 1.82;4.78) and coming from primary health care services (PR=3.13, 95% CI: 1.70;5.77) were more likely to achieve comprehensiveness in oral health care than other users. CONCLUSIONS: Users with better geographic accessibility, lower age and need of endodontic services were more likely to receive comprehensive health care. Implementation of Centers of Dental Specialists in cities where primary healthcare is not adequately structured is not recommended, because secondary health care would meet the free demand and perform basic procedures, thus not fulfilling the expected principle of comprehensiveness

Tree mode of death and mortality risk factors across Amazon forests

The carbon sink capacity of tropical forests is substantially affected by tree mortality. However, the main drivers of tropical tree death remain largely unknown. Here we present a pan-Amazonian assessment of how and why trees die, analysing over 120,000 trees representing > 3800 species from 189 long-term RAINFOR forest plots. While tree mortality rates vary greatly Amazon-wide, on average trees are as likely to die standing as they are broken or uprooted—modes of death with different ecological consequences. Species-level growth rate is the single most important predictor of tree death in Amazonia, with faster-growing species being at higher risk. Within species, however, the slowest-growing trees are at greatest risk while the effect of tree size varies across the basin. In the driest Amazonian region species-level bioclimatic distributional patterns also predict the risk of death, suggesting that these forests are experiencing climatic conditions beyond their adaptative limits. These results provide not only a holistic pan-Amazonian picture of tree death but large-scale evidence for the overarching importance of the growth–survival trade-off in driving tropical tree mortality

Worldwide comparison of survival from childhood leukaemia for 1995–2009, by subtype, age, and sex (CONCORD-2): a population-based study of individual data for 89 828 children from 198 registries in 53 countries

Background Global inequalities in access to health care are reflected in differences in cancer survival. The CONCORD programme was designed to assess worldwide differences and trends in population-based cancer survival. In this population-based study, we aimed to estimate survival inequalities globally for several subtypes of childhood leukaemia. Methods Cancer registries participating in CONCORD were asked to submit tumour registrations for all children aged 0-14 years who were diagnosed with leukaemia between Jan 1, 1995, and Dec 31, 2009, and followed up until Dec 31, 2009. Haematological malignancies were defined by morphology codes in the International Classification of Diseases for Oncology, third revision. We excluded data from registries from which the data were judged to be less reliable, or included only lymphomas, and data from countries in which data for fewer than ten children were available for analysis. We also excluded records because of a missing date of birth, diagnosis, or last known vital status. We estimated 5-year net survival (ie, the probability of surviving at least 5 years after diagnosis, after controlling for deaths from other causes [background mortality]) for children by calendar period of diagnosis (1995-99, 2000-04, and 2005-09), sex, and age at diagnosis (< 1, 1-4, 5-9, and 10-14 years, inclusive) using appropriate life tables. We estimated age-standardised net survival for international comparison of survival trends for precursor-cell acute lymphoblastic leukaemia (ALL) and acute myeloid leukaemia (AML). Findings We analysed data from 89 828 children from 198 registries in 53 countries. During 1995-99, 5-year agestandardised net survival for all lymphoid leukaemias combined ranged from 10.6% (95% CI 3.1-18.2) in the Chinese registries to 86.8% (81.6-92.0) in Austria. International differences in 5-year survival for childhood leukaemia were still large as recently as 2005-09, when age-standardised survival for lymphoid leukaemias ranged from 52.4% (95% CI 42.8-61.9) in Cali, Colombia, to 91.6% (89.5-93.6) in the German registries, and for AML ranged from 33.3% (18.9-47.7) in Bulgaria to 78.2% (72.0-84.3) in German registries. Survival from precursor-cell ALL was very close to that of all lymphoid leukaemias combined, with similar variation. In most countries, survival from AML improved more than survival from ALL between 2000-04 and 2005-09. Survival for each type of leukaemia varied markedly with age: survival was highest for children aged 1-4 and 5-9 years, and lowest for infants (younger than 1 year). There was no systematic difference in survival between boys and girls. Interpretation Global inequalities in survival from childhood leukaemia have narrowed with time but remain very wide for both ALL and AML. These results provide useful information for health policy makers on the effectiveness of health-care systems and for cancer policy makers to reduce inequalities in childhood survival
