Profile and scientific production of Brazilian researchers in dental materials

Aim: To describe the demographic characteristics and academic production of the National Council for the Development of Science and Technology (CNPq) researchers whose areas of expertise focus on dental materials. Methods: Secondary data were obtained from the details of dentistry researchers registered as receiving a CNPq grant for scientific productivity. Variables such as gender, category of scientific productivity grant, time of completion of PhD program, geographical distribution and affiliated institution, scientific production and human resources training were analyzed. Data from 2007-2009 triennium were considered. Mann-Whitney and chisquare tests compared the variables. Results: Researchers in categories 1A + 1B are those who completed their PhD program more than 14 years ago. All (100%) of dental material researchers are dentists and affiliated to universities, being approximately 92% of those affiliated to public institutions. Male gender (62.2%) and category 2 grant (40.5%) are prevalent, and a high concentration of CNPq grantees in the southeastern region (75.7%) was observed. In general, there was a predominance of publications in CAPES Qualis B journals (59.0%), but a predominance of publications by new doctors in CAPES Qualis A2 and B1 journals was found. A higher mean of publications of book chapters (0.97) compared with full publications of books (0.43) per researcher was observed. Annually, researchers supervised more scientific initiation grants (median = 0.45), followed by doctoral (mean = 0.36) and master students (median = 0.30). Conclusions: There is a high concentration of researchers in the southeastern region, predominance of male gender and scholars in grant category 2. Publications are mainly in CAPES Qualis B journals. and researchers in grant categories 1C and 1D and with less time doctoral produce more publications. The publication of books chapters is larger than entire books. The researchers supervised more undergraduate students, followed by PhD and master’s degree students annually

Características das mulheres com câncer de mama assistidas em serviços de referência do Norte de Minas Gerais

OBJETIVOS: Descrever as principais características de pacientes com câncer de mama admitidas em dois serviços de referência para o tratamento desse tipo de câncer no norte de Minas Gerais, incluindo estágio da doença ao diagnóstico e local de tratamento. MÉTODOS: Realizou-se estudo transversal e descritivo, avaliando 288 prontuários de pacientes do gênero feminino com câncer de mama, admitidas entre janeiro de 2006 a dezembro de 2009, oriundas de um serviço público e de um privado. As variáveis analisadas foram submetidas a tratamento estatístico por meio dos testes qui-quadrado e regressão logística multinomial. RESULTADOS: Observou-se que 68,1% da população analisada procediam do serviço público. Predominaram pacientes com mais de 50 anos (54,5%), casadas (59%) e com filhos (87,8%). Dentre a população estudada, a média de idade foi de 63 anos, sendo que em 42,7% dos casos prevaleceu o intervalo de tempo acima de 6 meses entre a suspeita clínica e a confirmação diagnóstica. Em 47,6% das mulheres o diagnóstico foi tardio (estágios III e IV). 20,1% tinham histórico familiar de câncer de mama; 20,8% faziam autoexame das mamas e 41% faziam mamografia. CONCLUSÃO: Verificou-se maior prevalência de pacientes nos estágios III e IV no serviço público quando comparado ao privado. O tempo prolongado entre a suspeita clínica e a confirmação diagnóstica, a ausência de história familiar de câncer de mama e a não realização de mamografia de rastreamento são observados, neste estudo, como os principais fatores associados ao diagnóstico tardio

Surgical rehabilitation of cleft lip and/or palate: evaluation of the Brazilian public health system

Objective: To evaluate the surgical rehabilitation of cleft lip and/or palate by the Brazilian public health system. Methods: Retrospective, analytical and comparative ecological study, with information on hospital procedures performed on individuals with cleft lip and/or palate in Centers authorized by the Brazilian public health system, between the years 2008 and 2020. The information was collected in databases Ministry of Health data. Results: Between 2008 and 2020, there was an increase of 8 (36.4%) qualified Centers in Brazil, currently having 30 Centers in 100% of the geographic regions. The surgical procedures performed totaled 68,716; with multiple surgeries being the most frequent. Complete cleft lip and palate was the most frequent type in hospital admissions. The public financial resources invested in the surgical rehabilitation of cleft lip and palate in the qualified Lip and Palate Malformation Treatment Centers were US$39,693 million, making an average value per procedure of US$ 577.64. Conclusions: In Brazil, public health system performed and financed, over the years 2008 and 2020, an important volume of surgical procedures for cleft lip and/or palate, which presented a polarization in the Southeast region but with a slight tendency expansion to other regions of the country. The most performed surgical procedures were multiple surgeries and mostly for individuals with cleft lip and palate. The amounts paid showed a heretogeneous distribution in the national territory. Level of evidence: Level 5: Report containing program evaluation data

Clinical relevance of breast and gastric cancer-associated polymorphisms as potential susceptibility markers for oral clefts in the Brazilian population

Abstract Background Epidemiological studies have indicated a higher incidence of breast and gastric cancer in patients with nonsyndromic cleft lip with or without cleft palate (NSCL ± P) and their relatives, which can be based on similar genetic triggers segregated within family with NSCL ± P. Methods This multicenter study evaluated the association of 9 single nucleotide polymorphisms (SNP) in AXIN2 and CDH1, representing genes consistently altered in breast and gastric tumors, with NSCL ± P in 223 trios (father, mother and patient with NSCL ± P) by transmission disequilibrium test (TDT). Results Our results showed that the minor A allele of rs7210356 (p = 0.01) and the T-G-G-A-G haplotype formed by rs7591, rs7210356, rs4791171, rs11079571 and rs3923087 SNPs (p = 0.03) in AXIN2 were significantly under-transmitted to patients with NSCL ± P. In CDH1 gene, the C-G-A-A and A-G-A-G haplotypes composed by rs16260, rs9929218, rs7186053 and rs4783573 polymorphisms were respectively over-transmitted (p = 0.01) and under-transmitted (p = 0.008) from parents to the children with NSCL ± P. Conclusions The results suggest that polymorphic variants in AXIN2 and CDH1 may be associated with NSCL ± P susceptibility, and reinforce the putative link between cancer and oral clefts

Profile and scientific production of Brazilian National Council of Technological and Scientific Development researchers in Pediatrics

OBJECTIVE: To evaluate the profile and the scientific production of researchers in Pediatrics with scholarship from the National Counsel of Technological and Scientific Development. METHODS: The Lattes curricula of 34 researchers in Pediatrics with active scholarships, from 2006 to 2008 were included in the analysis. The variables of interest were: gender, affiliation, time since PHD, tutoring of undergraduate students, mentorship of masters and doctors, scientific production and the papers' impact. RESULTS: In a total of 411 researchers in Medicine, 34 (8%) belonged to Pediatrics. Males (77%) and scholars in the category 2 of productivity (62%) prevailed. Three states of Brazil were responsible for approximately 90% of the researchers: São Paulo (53%), Minas Gerais (21%), and Rio Grande do Sul (15%). During their academic career, the Pediatrics researchers have published 3,122 articles with a median of 89 articles per researcher (interquartile range - IQ=51-119). Of the total, 40 and 59% articles were indexed in the Web of Science and Scopus databases, respectively. The Pediatrics researchers have published papers in 599 journals with a median impact factor of 2.35 (IQ=1.37-3.73) for the 323 indexed journals. CONCLUSIONS: The Pediatrics researchers have a relevant scientific output from the quantity point of the view, but there is a need to improve quality
