Dermatite Atópica: Perfil Epidemiológico e Condições Alérgicas Associadas – Dados de um Serviço de Referência no Sudeste do Brasil

Introduction: Atopic dermatitis is a chronic, inflammatory and pruritic dermatosis of high prevalence, especially in childhood, constituting a relevant problem for public health. Several factors are associated with an increased risk for atopic dermatitis: genetic, psychological, infectious, food, environmental, among others, and atopic dermatitis may be associated with other manifestations of atopy, such as asthma and rhinitis. This study aimed to determine the epidemiological profile and the prevalence of personal and family history of allergy in children with atopic dermatitis attended at a reference service, comparing it to the existing literature. Methods: Hospital-based, cross-sectional and descriptive study, involving children of both genders under 18 years old with a clinical diagnosis of atopic dermatitis (Hanifin and Rajka criteria) attended at the Pediatric Dermatology Outpatient Clinic of the Hospital Municipal Universitário de Taubaté (H.MUT), SP – Brazil, from October 2018 to April 2019. Epidemiological data and data related to personal and family history of allergies were collected from medical records. Microsoft Excel 2019 was used for data analysis and compilation. Results: Of the 440 consultations carried out in the period, 35 (7.9%) were for atopic dermatitis, 23 females (65.7%), 15 phototype IV (42.9%) with mean age 7.7 years (standard deviation=4.3), with disease duration from 2 months to 14 years (mean 5.3 years – standard devia- tion=4.3). Thirty-one patients (88.6%) manifested the condition up to the fifth year of life. Personal history of allergies was present in 77.1% (27 individuals), with a predominance of allergic rhinitis and in older age groups. Positive family history in 62.9% (22 individuals). Conclusion: Pioneer study in the region; it allowed the determination of the epidemiological profile of patients with atopic dermatitis at the Pediatric Dermatology Clinic of the H.MUT, revealing an early onset and higher prevalence in females and in individuals with high phototypes. In addition, it identified the prevalence of personal and family history of allergy in these patients, data consistent with the literature.Introdução: A dermatite atópica é uma dermatose crónica, inflamatória e pruriginosa de alta prevalência, principalmente na infância, constituindo um problema relevante para a saúde pública.

Insights Into Immune Responses In Oral Cancer Through Proteomic Analysis Of Saliva And Salivary Extracellular Vesicles

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The development and progression of oral cavity squamous cell carcinoma (OSCC) involves complex cellular mechanisms that contribute to the low five-year survival rate of approximately 20% among diagnosed patients. However, the biological processes essential to tumor progression are not completely understood. Therefore, detecting alterations in the salivary proteome may assist in elucidating the cellular mechanisms modulated in OSCC and improve the clinical prognosis of the disease. The proteome of whole saliva and salivary extracellular vesicles (EVs) from patients with OSCC and healthy individuals were analyzed by LC-MS/MS and label-free protein quantification. Proteome data analysis was performed using statistical, machine learning and feature selection methods with additional functional annotation. Biological processes related to immune responses, peptidase inhibitor activity, iron coordination and protease binding were overrepresented in the group of differentially expressed proteins. Proteins related to the inflammatory system, transport of metals and cellular growth and proliferation were identified in the proteome of salivary EVs. The proteomics data were robust and could classify OSCC with 90% accuracy. The saliva proteome analysis revealed that immune processes are related to the presence of OSCC and indicate that proteomics data can contribute to determining OSCC prognosis.5Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)FAPESP [2009/54067-3, 2010/19278-0]CNPq [470549/2011-4, 301702/2011-0, 470268/2013-1

Environmental factors can influence dengue reported cases

Introduction: Global climate changes directly affect the natural environment and contribute to an increase in the transmission of diseases by vectors. Among these diseases, dengue is at the top of the list. The aim of our study was to understand the consequences of temporal variability of air temperature in the occurrence of dengue in an area comprising seven municipalities of the Greater Sao Paulo. Method: Characterization of a temporal trend of the disease in the region between 2010 and 2013 was performed through analysis of the notified number of dengue cases over this period. Our analysis was complemented with meteorological (temperature) and pollutant concentration data (PM10). Results: We observed that the months of January, February, March, April and May (from 2010 to 2013) were the ones with the highest number of notified cases. We also found that there is a statistical association of moisture and PM10 with the reported cases of dengue. Conclusion: Although the temperature does not statistically display an association with recorded cases of dengue, we were able to verify that temperature peaks coincide with dengue outbreak peaks. Future studies on environmental pollution and its influence on the development of Aedes aegypti mosquito during all stages of its life cycle, and the definition of strategies for better monitoring, including campaigns and surveillance, would be compelling.ABC, FM, Santo Andre, SP, BrazilCoimbra Hlth Sch, Environm Hlth IPC, EsTesC, Coimbra, PortugalEsTesC, Coimbra Hlth Sch, Dept Ciencias Complementares IPC, Coimbra, PortugalFMABC, Gestao Saude Ambiental, Santo Andre, SP, BrazilUniv Fed Sao Paulo Unifesp, Biol Sci Dept, Diadema, SP, BrazilUniv Fed Sao Paulo Unifesp, Biol Sci Dept, Diadema, SP, BrazilWeb of Scienc

The Ninth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Baryon Oscillation Spectroscopic Survey

The Sloan Digital Sky Survey III (SDSS-III) presents the first spectroscopic data from the Baryon Oscillation Spectroscopic Survey (BOSS). This ninth data release (DR9) of the SDSS project includes 535,995 new galaxy spectra (median z=0.52), 102,100 new quasar spectra (median z=2.32), and 90,897 new stellar spectra, along with the data presented in previous data releases. These spectra were obtained with the new BOSS spectrograph and were taken between 2009 December and 2011 July. In addition, the stellar parameters pipeline, which determines radial velocities, surface temperatures, surface gravities, and metallicities of stars, has been updated and refined with improvements in temperature estimates for stars with T_eff<5000 K and in metallicity estimates for stars with [Fe/H]>-0.5. DR9 includes new stellar parameters for all stars presented in DR8, including stars from SDSS-I and II, as well as those observed as part of the SDSS-III Sloan Extension for Galactic Understanding and Exploration-2 (SEGUE-2). The astrometry error introduced in the DR8 imaging catalogs has been corrected in the DR9 data products. The next data release for SDSS-III will be in Summer 2013, which will present the first data from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) along with another year of data from BOSS, followed by the final SDSS-III data release in December 2014.Comment: 9 figures; 2 tables.

Mucosal immunization with PspA (Pneumococcal surface protein A)-adsorbed nanoparticles targeting the lungs for protection against pneumococcal infection

Burden of pneumonia caused by Streptococcus pneumoniae remains high despite the availability of conjugate vaccines. Mucosal immunization targeting the lungs is an attractive alternative for the induction of local immune responses to improve protection against pneumonia. Our group had previously described the development of poly(glycerol adipate-co-ω-pentadecalactone) (PGA-co-PDL) polymeric nanoparticles (NPs) adsorbed with Pneumococcal surface protein A from clade 4 (PspA4Pro) within L-leucine microcarriers (nanocomposite microparticles-NCMPs) for mucosal delivery targeting the lungs (NP/NCMP PspA4Pro). NP/NCMP PspA4Pro was now used for immunization of mice. Inoculation of this formulation induced anti-PspA4Pro IgG antibodies in serum and lungs. Analysis of binding of serum IgG to intact bacteria showed efficient binding to bacteria expressing PspA from clades 3, 4 and 5 (family 2), but no binding to bacteria expressing PspA from clades 1 and 2 (family 1) was observed. Both mucosal immunization with NP/NCMP PspA4Pro and subcutaneous injection of the protein elicited partial protection against intranasal lethal pneumococcal challenge with a serotype 3 strain expressing PspA from clade 5 (PspA5). Although similar survival levels were observed for mucosal immunization with NP/NCMP PspA4Pro and subcutaneous immunization with purified protein, NP/NCMP PspA4Pro induced earlier control of the infection. Conversely, neither immunization with NP/NCMP PspA4Pro nor subcutaneous immunization with purified protein reduced bacterial burden in the lungs after challenge with a serotype 19F strain expressing PspA from clade 1 (PspA1). Mucosal immunization with NP/NCMP PspA4Pro targeting the lungs is thus able to induce local and systemic antibodies, conferring protection only against a strain expressing PspA from the homologous family 2
