RESUMO O suporte social permite quebrar dificuldades de participação social de alunos com necessidades educativas específicas. O objetivo do estudo foi conhecer a perspetiva de alunos com deficiência auditiva, visual, físico-motora e dificuldades específicas de aprendizagem sobre o que consideram ser suporte social. Para tal, foi desenvolvido um estudo de natureza qualitativa. Foram realizadas entrevistas semiestruturadas a 15 alunos com estas condições (do 3.º ao 12.º, com idades entre os 8 e 18 anos). As respostas foram analisadas a partir de categorias previamente definidas, tendo emergido um conjunto de subcategorias a partir dos dados. Os alunos valorizaram a disponibilidade dos seus colegas e professores para os apoiar e os envolver nas atividades da turma e a expressão de empatia e cuidado. Referiram também situações de rejeição e exclusão. No artigo são discutidas condições que favorecem o conhecimento do outro e uma cultura de suporte social recíproco, essenciais para a participação social.

ABSTRACT Social support is essential for overcoming the difficulties that students with special educational needs face in interacting with peers. The goal of the study was to explore the perspective of students presenting with hearing, visual and physical or motor deficiencies and specific learning difficulties about what they consider to be social support. To this end, we developed a qualitative study. Semi-structured interviews were conducted with 15 students (3rd to the 12th grade; 8 to 18 years old). Answers were analyzed from previously defined categories, subcategories emerged from the data. Students valued the availability of their classmates and teachers to support and involve them in class activities, as well as expressions of empathy, care and attention. Students mentioned situations of rejection and exclusion. The paper discusses conditions that favor mutual knowledge and a culture of reciprocal social support, both of which are essential to facilitate students’ social participation.

Abstract Objectives To compare LISA with INSURE technique for surfactant administration in preterm with gestational age (GA) < 36 weeks with RDS in respect to the incidence of pneumothorax, bronchopulmonary dysplasia (BPD), need for mechanical ventilation (MV), regional cerebral oxygen saturation (rSO2), peri‑intraventricular hemorrhage (PIVH) and mortality. Methods A systematic search in PubMed, Embase, Lilacs, CINAHL, SciELO databases, Brazilian Registry of Randomized Clinical Trials (ReBEC), Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) was performed. RCTs evaluating the effects of the LISA technique versus INSURE in preterm infants with gestational age < 36 weeks and that had as outcomes evaluation of the rates of pneumothorax, BPD, need for MV, rSO2, PIVH, and mortality were included in the meta-analysis. Random effects and hazard ratio models were used to combine all study results. Inter-study heterogeneity was assessed using Cochrane Q statistics and Higgin's I2 statistics. Results Sixteen RCTs published between 2012 and 2020 met the inclusion criteria, a total of 1,944 preterms. Eleven studies showed a shorter duration of MV and CPAP in the LISA group than in INSURE group. Two studies evaluated rSO2 and suggested that LISA and INSURE transiently affect brain autoregulation during surfactant administration. INSURE group had a higher risk for MV in the first 72 h of life, pneumothorax, PIVH and mortality in comparison to the LISA group. Conclusion This systematic review and meta-analyses provided evidence for the benefits of the LISA technique in the treatment of RDS, decreasing CPAP time, need for MV, BPD, pneumothorax, PIVH, and mortality when compared to INSURE.

ABSTRACT: Leptospirosis, a disease of significant economic impact on livestock and public health concern, may exhibit unique epidemiological characteristics in indigenous villages, particularly those located within semiarid climates such as the Caatinga biome in Brazil. This environment often presents conditions unfavorable for leptospire survival. This study conducted serological diagnoses of livestock in indigenous villages within the Caatinga biome, Northeastern Brazil. The survey was carried out in the Mãe Maria and Santa Helena indigenous villages, home to the Xukuru de Cimbres tribe, in the county of Pesqueira, Pernambuco State, Brazil, within the Caatinga biome. Blood samples were collected from cattle (n = 42), goats (n = 41), and sheep (n = 19). Out of the 102 samples tested, 73 (71.6%; 95% CI = 62.8% - 80.3%) were seroreactive (cut-off ≥ 100). The seropositivity rates for cattle, goats, and sheep were 54.8%, 80.5%, and 89.5%, respectively. A statistically significant difference was observed in the proportion of seropositive animals between cattle and goats and cattle and sheep (P < 0.05). Icterohaemorrhagiae was identified as the most probable serogroup across all animal species. The study revealed that livestock in indigenous villages within the Caatinga biome are frequently exposed to leptospires. This finding underscores the importance of a One Health approach, emphasizing the need for comprehensive studies in areas where large human and animal populations coexist. Such studies are crucial for investigating zoonotic infections and for planning and implementing control measures against livestock-associated leptospirosis.

RESUMO: A leptospirose causa perdas econômicas na pecuária e é um problema de saúde pública, sendo possível que existam peculiaridades na epidemiologia dessa doença em aldeias indígenas, principalmente naquelas de áreas de clima semiárido, como o bioma Caatinga no Nordeste do Brasil, onde o ambiente é frequentemente adverso à sobrevivência de leptospiras. Assim, o objetivo deste estudo foi realizar o diagnóstico sorológico em rebanhos de aldeias indígenas no bioma Caatinga. A pesquisa foi realizada nas aldeias indígenas Mãe Maria e Santa Helena, tribo Xukuru de Cimbres, município de Pesqueira, estado de Pernambuco, Brasil, dentro do bioma Caatinga. Amostras de sangue foram colhidas de bovinos (n = 42), caprinos (n = 41) e ovinos (n = 19). No geral, das 102 amostras testadas 73 (71,6%; IC 95% = 62,8% - 80,3%) foram sororreativas (ponto de corte ≥ 100). Para bovinos, caprinos e ovinos as taxas de soropositividade foram de 54,8%, 80,5% e 89,5%, respectivamente. Houve diferença estatística na proporção de animais soropositivos entre bovinos e caprinos e bovinos e ovinos (P < 0,05). Icterohaemorrhagiae foi o sorogrupo mais provável em todas as espécies animais. O estudo mostra que animais de produção de aldeias indígenas são comumente expostos a leptospiras no bioma Caatinga, o que constitui uma preocupação do ponto de vista de Saúde Única e demonstra a importância de estudos amplos em que coexistem grandes números de humanos e animais na investigação de infecções zoonóticas e no planejamento e implementação de medidas de controle da leptospirose associada a animais de produção.

Abstract Objective: To analyze the association between osteolysis at the prosthesis interfaces, as determined by magnetic resonance imaging (MRI) with multiacquisition variable-resonance image combination selective (MAVRIC-SL) sequences, and clinical severity after knee or hip arthroplasty, as well as to assess interobserver and intraobserver agreement on periprosthetic bone resorption. Materials and Methods: This was a cross-sectional study of 47 patients (49 joints) under postoperative follow-up after knee or hip arthroplasty, with chronic pain, between March 2019 and August 2020. All of the patients completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. The component interfaces were evaluated and ordered into two groups: osseointegrated and osteolytic. Nonparametric tests were used. Results: There were significant differences between the two groups in terms of the mean WOMAC scores: total (p = 0.010); stiffness domain (p = 0.047); and function (p = 0.011) domains. There was substantial interobserver and intraobserver agreement for most analyses of the components. Conclusion: Periprosthetic osteolysis appears to be associated with clinical complaints of pain in the post-arthroplasty scenario, and MAVRIC-SL provides reproducible assessments. It could prove to be an important tool for orthopedists to use in the evaluation of challenging cases of chronic pain after arthroplasty.

Resumo Objetivo: Analisar associação entre osteólise nas interfaces protéticas por ressonância magnética com sequências MAVRIC-SL e a gravidade clínica dos pacientes submetidos a artroplastias de joelho ou quadril. Determinar concordância intraobservador e interobservador na reabsorção óssea peri-implante. Materiais e Métodos: Foi realizado estudo transversal entre março de 2019 e agosto de 2020, com 47 pacientes (49 articulações) em seguimento pós-operatório de artroplastias de joelho ou quadril, com dor crônica, que responderam ao questionário WOMAC. As interfaces dos componentes foram avaliadas e definiram dois grupos: osteointegrado e osteólise. Testes não paramétricos foram usados. Resultados: Houve diferença significativa na média do escore WOMAC entre os grupos (p = 0,010), assim como nos domínios rigidez (p = 0,047) e função (p = 0,011). Houve concordância substancial interobservador e intraobservador para a maioria dos componentes analisados. Conclusão: Osteólise periprótese parece estar associada com a queixa clínica de dor pós-artroplastia, com avaliação reprodutível pela MAVRIC-SL. Isto pode ser uma importante ferramenta para o ortopedista na avaliação de casos desafiadores de dor crônica pós-artroplastia.

Abstract This study evaluated color stability (CS), anti-adherence effect (AAE), and cell viability of microorganisms on acrylic resin (AR) surface, treated associated or not with sodium percarbonate (SP). AR specimens were prepared, and color analysis was performed before and after the treatments and the CS was calculated. For analysis of AAE, the samples were sterilized by radiation in a microwave oven. Then samples were randomly distributed: phosphate-buffered saline (PBS - control), 0.5% sodium hypochlorite (SH), phytosphingosine (PHS), and phytosphingosine + SP (PHS+Na2CO3). The specimens remained in contact with solutions for 30 minutes and were later contaminated by Candida albicans. Aliquots were seeded in Petri dishes with Sabouraud Dextrose agar and incubated at 37°C for 24 hours. After the incubation, the number of colonies was counted. The cell viability of adhered microorganisms on the AR was evaluated and 20 fields were observed under an epifluorescence microscope, and the percentage of adhered viable cells was calculated. Data were compared (One-way ANOVA, Tukey, p<.05). As for CS, PHS+ Na2CO3 (0.4±0.1) resulted in less change than PBS (0.9±0.2), similar to the other groups (SH [1.0±0.3)]; PHS [0.9±0.2)]). There was no difference for all tested solutions regarding the ability to avoid microorganism adherence (p>0.05), but PHS (11.2±4.1) resulted in a smaller area of adhered viable cells, statistically different from SH (18.2±7.6) and PBS (26.4±10.8). It was concluded that PHS resulted in lower adhered viable cells and when associated with Na2CO3, also shows a lower effect on the CS of AR.

Resumo Este estudo avaliou estabilidade de cor (EC), efeito antiaderente (EAA) e viabilidade celular de microrganismos em superfície de resina acrílica (RA), tratada com solução de fitoesfingosina, associada ou não ao percarbonato de sódio (PS). Espécimes RA foram preparados e análise de cor foi realizada antes e após os tratamentos e EC foi calculada. Para análise de EAA, as amostras foram esterilizadas por radiação em forno de micro-ondas. Então foram distribuídas aleatoriamente: solução salina tamponada com fosfato (PBS - controle), hipoclorito de sódio 0,5% (SH), fitoesfingosina (PHS) e fitoesfingosina + SP (PHS+Na2CO3). Os espécimes permaneceram em contato com as soluções por 30 minutos e posteriormente foram contaminados por Candida albicans. Alíquotas foram semeadas em placas de Petri com ágar Sabouraud Dextrose e incubadas a 37°C por 24 horas. Após a incubação, o número de colônias foi contado. A viabilidade celular dos microorganismos aderidos na RA foi avaliada e 20 campos foram observados em microscópio de epifluorescência, e a porcentagem de células viáveis aderidas foi calculada. Os dados foram comparados (One-way ANOVA, Tukey, p<0,05). Quanto a EC, o PHS+ Na2CO3 [0,4 (0,1)] resultou em menor alteração que o PBS [0,9 (0,2)], semelhante aos demais grupos (SH [1,0 (0,3)]; PHS [0,9 (0,2)]). Não houve diferença para todas as soluções testadas quanto à capacidade de evitar a aderência de microorganismos (p>0,05), mas o PHS [11,2 (4,1)] resultou em uma área menor de células viáveis aderidas, estatisticamente diferente do SH [18,2 (7,6)] e PBS [26,4 (10,8)]. Concluiu-se que o PHS resultou em menor número de células viáveis aderidas e, quando associado ao Na2CO3, também apresenta menor efeito sobre o EC da RA.

Abstract Objective Few studies have addressed the use of sacral nerve stimulation (SNS) in the treatment of patients with multiple pelvic floor dysfunctions (PFD). So, we evaluated the functional outcomes and level of satisfaction with SNS in selected patients with one or multiples PFD. Methods A prospective database was used to collect information on eligible patients treated for PFD with SNS, and severity of symptoms was assessed with scores and satisfaction rates by visual analogue scale (VAS) at baseline and by the end of follow-up. Results We recruited 70 patients, 98.6% of whom responded positively during the evaluation period (Global Response Assessment ≥ 50% for at least one type of PFD), resulting in the implantation of a permanent SNS device. Additionally, 49 of the patients (71%) had a single PFD (fecal incontinence [FI] = 38; constipation/obstructed defecation syndrome [C/ODS] = 11), while 20 (29%) had more than one PFD (double incontinence/n = 12; double incontinence + C/ODS/n = 8). All scores improved significantly between baseline (pre-SNS) and the end of follow-up (post-SNS), as did VAS in all groups (single and multiple PFD). The pre-SNS scores were higher in patients with a single PFD, including FI (Cleveland clinic Florida incontinence score [CCF-FI]) and C/ODS (Cleveland clinic constipation score [C-CCF] and the Renzi ODS score). The pre-SNS impact of VAS scores was similar in all groups (single and multiple PFD), but the VAS (post-SNS) was significantly lower (better response) for FI alone compared with multiple PFD. Conclusion The SNS technique is an effective and safe option for patients with one or more PFD refractory to conservative measures. Response was positive for at least two PFD, based on reduced correspondent scores and satisfaction rate.

This is a multicenter, cross-sectional study carried out with students regularly enrolled in undergraduate courses at eight Brazilian IFES. Data collection was conducted between October 2021 and February 2022 using an online self-completed questionnaire, which addressed sociodemographic and academic characteristics, lifestyle habits, and health conditions. Symptoms of anxiety and depression were assessed using the Depression, Anxiety, and Stress Scale-21 (DASS-21). Variables were analyzed descriptively using frequency distribution and Pearson’s chi-square test. To estimate the prevalence of symptoms of anxiety and depression, the proportion and 95% confidence interval (95%CI) were used. The level of adopted statistical significance was 5%.

Abstract The scope of this paper is to elicit reflection on therapy clowns in the realm of Popular Education in Health. It describes and analyzes interventions conducted between October 2020 and December 2021 between civil service workers and patients in the Sertão Central hinterlands. Therapy clowning paved the way as a potent technology for humanized care treatment by the resident nurse. As an intermediary between scientific and popular knowledge, in its scenopoetic approach, it dealt creatively and humorously with taboo subjects for community health, promoting a light-hearted interaction experience with its audience. The experience revealed some points about the scarcity of investment to make projects like this viable, thereby empowering the institutionalization of Popular Education in Health. For this reason, we advocate the implementation of training sessions and workshops on concepts, challenges, and potentialities in Popular Education in Health. Therapy clowning, as a proposed action, is a transformative technology that inspires a proactive approach in the community through knowledge, loving care, and art.

Abstract Overview and Aims: Pregnancy is an opportunity to perform postpartum contraceptive counselling, which is important to reduce the rate of unwanted pregnancies. With the purpose of knowing the attitudes, behaviours and concerns of health professionals about contraception in the postpartum period, a multicentre study was conducted in Portugal. Study design, population and methodology: A questionnaire with questions related to attitudes, practices and concerns of contraceptive counselling in pregnancy and postpartum was created and distributed in six hospital centres. This survey was intended for health professionals (physicians and nurses) and was conducted in order to ensure the anonymity and confidentiality of the participants. Descriptive study of the answers obtained. Results: There were 310 answers: 175 from doctors (56,5%) and 135 from nurses (43,5%). During pregnancy, 35.5% (n=110) always inform the woman about contraceptive options and 18.1% (n=56) if the possibility of tubal ligation arises. At discharge, the majority (81.6%, n=253) inform and advise about contraceptive options. There are 45 professionals (14.5%) who do not inform women, pointing out as reasons ‘the not appropriateness of the moment’ and ‘lack of time’. The majority of respondents consider that women should have contraceptive counselling during pregnancy (78.4%, n=243) and about one fifth (21.6%, n=67) do not. The reasons given being: ‘information should be referred to the postpartum review consultation’ and ‘the information given at discharge is sufficient’ (41.8%, n=28). In this group, 25.4% (n=17) does not intend to change their attitude, 11.9% (n=8) states that they will change their attitude e 46.3% (n=31) consider changing their attitude. Conclusions: In the population studied, contraceptive counselling during pregnancy is not universal. Although most of the professionals considered contraceptive counselling during pregnancy important, in current practice it is deferred to maternity discharge or to the postpartum review consultation.

Resumo Introdução e objetivos: A gravidez constitui uma oportunidade para realizar aconselhamento contracetivo para o pós-parto, sendo este importante para reduzir a taxa de gravidez não desejada. Com o objetivo de conhecer as atitudes, comportamentos e preocupações dos profissionais de saúde sobre a contraceção no pós-parto foi realizado um estudo multicêntrico em Portugal. Desenho do estudo, população e metodologia: Foi elaborado um questionário para profissionais de saúde (médicos e enfermeiros) que foi distribuído em seis centros hospitalares. Foi garantido o anonimato e confidencialidade dos participantes. Procedeu-se a um estudo descritivo das respostas obtidas. Resultados: Obtiveram-se 310 respostas: 175 de médicos (56.5%) e 135 de enfermeiros (43.5%). Durante a gravidez, 35.5% (n=110) informa sempre a mulher das opções contracetivas, 36.5% (n=113) informa apenas em situações especiais e 18.1% (n=56) se a hipótese de laqueação tubária se colocar. Na alta da maternidade, a maioria (81.6%, n=253) informa e orienta sobre as opções contracetivas. Existem 45 (14.5%) profissionais que não informam a mulher sobre contraceção, apontando como razões a ‘não adequação do momento’ e a ‘falta de tempo’. A maioria dos inquiridos considera que a mulher deve ter aconselhamento contracetivo durante a gravidez (78.4%, n=243) e cerca de um quinto (21.6%, n=67) considera que não, sendo os motivos apontados: ‘esta informação deve ser remetida para a consulta de revisão puerperal’ e ‘a informação dada na alta é suficiente’. Neste grupo, 25.4% não tenciona mudar a sua atitude e 46.3% pondera modificar esta atitude. Conclusões: Na população avaliada, o aconselhamento contracetivo não é universal. A maioria dos profissionais considera importante que o aconselhamento contracetivo deve ser realizado durante a gravidez. No entanto, na prática atual o aconselhamento contracetivo é diferido para a alta da maternidade ou para a consulta de revisão puerperal.

Abstract This study evaluated the effect of phytosphingosine (PHS) and bioactive glass-ceramic (Biosilicate) on dental enamel in terms of color alteration (ΔE), microhardness, and surface roughness when submitted to erosive challenge (EC). Sixty specimens of bovine teeth (6×6×2mm) were obtained. Initial color (Easyshade, VITA), KHN (HMV-2, Shimadzu), and Ra (SJ-201P, Mitutoyo) measurements were performed. Specimens were separated into groups according to treatments: PHS, 10% Biosilicate, PHS+10% Biosilicate, and artificial saliva (control) and submitted to EC with Coca-Cola for 2 min. This cycle was repeated 4 times daily/15 days. Between cycles, specimens remained in artificial saliva (2 h/37°C). After daily cycles, they were also stored in artificial saliva at 37ºC. Final color, microhardness, and surface roughness measurements were done. Color and KHN data were analyzed by one-way ANOVA, Tukey’s test; and Ra, by 2-way ANOVA, repeated measures, and Tukey’s test (p<.05). The highest ΔE occurred in Saliva+EC (p<.05). Groups treated with PHS presented lower color change than Saliva+EC (p<.05). All the groups presented mean values above the 50:50% perceptibility (50:50%PT) and acceptability (50:50%AT) thresholds, except for control that showed mean value above 50:50%PT but below 50:50%AT. Biosilicate+EC showed higher relative microhardness than Saliva+EC (p<.05), but was similar to PHS+EC and PHS+Biosilicate+EC. Final enamel surface roughness increased for all the groups (p<.05), except for the control. The Biosilicate may prevent enamel mineral loss induced by erosion better than saliva. The PHS associated or not to Biosilicate demonstrated better color stability than saliva.

Resumo Este estudo avaliou o efeito da Fitoesfingosina (PHS) e da vitrocerâmica bioativa (Biosilicato) sobre o esmalte dental em termos de alteração de cor (ΔE), microdureza (KHN) e rugosidade superficial, quando submetido a desafio erosivo (DE). Sessenta espécimes de dentes bovinos (6×6×2mm) foram obtidos. Foram realizadas leituras de cor inicial (Easyshade, VITA), microdureza (HMV-2, Shimadzu) e rugosidade superfícial (SJ-201P, Mitutoyo). Os espécimes foram separados em grupos de acordo com os tratamentos: PHS, Biosilicato a 10%, PHS+Biosilicato a 10%, e saliva artificial (controle). Em seguida, foram submetidos a DE com Coca-Cola por 2 min. Esse ciclo foi repetido 4 vezes/dia por 15 dias. Entre os ciclos, as amostras foram mantidas em saliva artificial (2 h/37°C). Após os ciclos diários, os espécimes também foram armazenados em saliva artificial a 37ºC. Foram realizadas leituras finais de cor, microdureza e rugosidade superficial. Os dados de cor e microdureza foram analisados por ANOVA de uma via, teste de Tukey; e dados de rugosidade superficial, por ANOVA de duas vias, teste de Tukey (p<.05). A maior ΔE ocorreu em Saliva+DE (p<.05). Grupos tratados com PHS apresentaram menor alteração de cor do que Saliva+DE (p<.05). Biosilicate+DE demonstrou valores intermediários, similar (p>.05) aos outros grupos, exceto Saliva+DE. Todos os grupos presentaram média acima dos limites 50:50% de perceptibilidade (50:50%LP) e aceitabilidade (50:50%LA) exceto o controle que demonstrou média acima do 50:50%LA mas abaixo do 50:50%LP. Biosilicate+DE mostrou maior microdureza realativa do que Saliva+DE (p<.05), mas similar a PHS+DE e PHS+Biosilicato+DE. A rugosidade de superfície do esmalte aumentou para todos os grupos, exceto para o controle que presentou a menor alteração (p<.05). O Biosilicato apode prevenir perda mineral do esmalte indizido pela erosão melhor que a saliva. O PHS associado ou não ao Biosilicato demonstrou melhor estabilidade de cor que a saliva.

ABSTRACT Objectives: We aimed to evaluate the association between the triglyceride glucose index (TyG index) and sleep quality and to establish a cut-off value for the TyG index based on the prevalence of subjects with insulin resistance (IR). Materials and methods: This cross-sectional study involved Brazilian health professionals (20-59 years). A total of 138 subjects answered the Pittsburgh Sleep Quality questionnaire to evaluate sleep quality. They were categorized into two groups: good sleep quality (global score ≤ 5 points) and poor sleep quality (global score ≥ 6 points). Also, we classified the subjects as having a high (>8.08 or >4.38) or low TyG index (≤8.08 or ≤4.38). Results: The majority of the subjects (70%) with high TyG index values (>8.08 or >4.38) reported poor sleep quality (p ≤ 0.001). Those with poor sleep quality had a 1.44-fold higher prevalence of IR (TyG index >8.08 or >4.38) compared to those with good sleep quality, regardless of sex, total cholesterol, LDL/HDL ratio, insulin, complement C3, CRP, and adiponectin (p ≤ 0.001). Conclusion: Our data showed a positive and significant association between the TyG index and poor sleep quality. Thus, these findings support the association between poor sleep quality and IR.

Abstract The aim of this in situ study was to evaluate color change, surface roughness, gloss, and microhardness in tooth enamel submitted to whitening and remineralizing toothpastes. Fifteen healthy adults (REBEC - RBR-7p87yr) (with unstimulated salivary flow ≥ 1.5 ml for 5 minutes, pH=7) wore two intraoral devices containing four bovine dental fragments (6 x 6 x 2 mm). Participants were randomly assigned and instructed to toothbrush the devices with the tested toothpastes (30 days): CT: conventional; WT: whitening; WTP: whitening with peroxide, and RT: remineralizing toothpaste. A washout period of 7 days was established. Readouts of color, gloss, surface roughness, and microhardness were performed before and after brushing. The results demonstrated no color, gloss, and microhardness differences (p>0.5). The samples brushed with WTP (0.2(0.7) showed higher surface roughness (p=0.0493) than those with WT (-0.5(1.0). The toothpastes did not alter the properties of the dental enamel, except for the roughness. Toothpaste with an abrasive system based on sodium bicarbonate and silica, and that contains sodium carbonate peroxide increased the surface roughness of the enamel.

Resumo O objetivo deste estudo in situ foi avaliar a alteração de cor, rugosidade superficial, brilho e microdureza em esmalte dentário submetido a dentifrícios clareadores e remineralizantes. Quinze adultos saudáveis (REBEC - RBR-7p87yr) (com fluxo salivar não estimulado ≥ 1.5 mL por 5 minutos, pH = 7) usaram dois dispositivos intrabucais contendo quatro fragmentos dentários bovinos (6 x 6 x 2 mm). Os participantes foram aleatoriamente designados e instruídos a escovar os aparelhos com os dentifrícios testados (30 dias): CO: convencional; CL: clareador; CLP: clareador com peróxido e RE: remineralizante. Foi estabelecido um período de washout de 7 dias. Leituras de cor, brilho, rugosidade superficial e microdureza foram realizadas antes e após a escovação. Os resultados não demonstraram diferenças na cor, brilho e microdureza. As amostras escovadas com CLP apresentaram maior rugosidade superficial (p=0,0493) do que aquelas com CL. Os dentifrícios não alteraram as propriedades do esmalte dental, exceto a rugosidade. O dentifrício com sistema abrasivo à base de bicarbonato de sódio e sílica, e que contém peróxido de carbonato de sódio aumentou a rugosidade de superfície do esmalte.

Objective: to estimate the reference intervals (RIs) of complete blood count parameters in the Brazilian adult population. Methods: Cross-sectional study, with data from the National Health Survey (PNS), between 2014-2015. The final sample consisted of 2,803 adults. The final sample consisted of 2,803 adults. To establish the RI, exclusion criteria were applied, outliers were removed and partitions were made by sex, age and race/skin color. The non-parametric method was adopted. Differences were assessed using the Mann Withney and Kruskal Wallis tests (p≤0.05). Results: There were statistically significant differences for the following hematological parameters based on sex, red blood cells, hemoglobin, hematocrit, MCH, MCHC, eosinophils and absolute monocytes, neutrophils and platelets (p≤0.05). When analyzed by age, the RIs were statistically different in females for hematocrit, MCV, white blood cells and RDW and in males for red blood cells, white blood cells, eosinophils, mean platelet volume, MCV, RDW and MCH(p≤0.05). For race/color there were differences in the RIs for parameters of hemoglobin, MCH, MCHC, white blood cells and mean platelet volume, neutrophils and absolute eosinophils (p ≤ 0.05). Conclusion: The differences found in the RIs of some in blood count parameters in Brazilian adults reaffirm the importance of having their own laboratory reference standards. The results can support a more accurate interpretation of tests, adequate identification and disease prevention in Brazil.

Objetivo: estimar os intervalos de referência (IR) de parâmetros de hemograma completo na população adulta brasileira. Métodos: Estudo transversal, com dados da Pesquisa Nacional de Saúde (PNS), entre 2014-2015. A amostra final constitui-se de 2.803 adultos. Para estabelecer os IR, aplicou-se critérios de exclusão, removeram-se outliers e feito particionamentos por sexo, idade e raça/cor da pele. Adotou-se o método não paramétrico.nbsp; As diferenças foram avaliadas pelos testes Mann Withney e Kruskal Wallis (p≤0,05). Resultados: houve diferenças estatisticamente significativas nos IR segundo sexo para glóbulos vermelhos, hemoglobina, hematócrito, HCM, CHCM, eosinófilos, monócitos, neutrófilos absolutos e plaquetas (p≤0,05). Quando analisados por idade,nbsp; houve diferenças nos IR de mulheres para hematócrito, VCM, glóbulos brancos e RDW e nos homens de glóbulos vermelhos, glóbulos brancos, eosinófilos, volume plaquetário médios, VCM, RDW e HCM (p≤0,05). Para raça/cor houve diferenças nos IR de hemoglobina, HCM, CHMC, glóbulos brancos e volume plaquetário médio, neutrófilos e eosinófilos absolutos (p ≤ 0,05). Conclusão: As diferenças encontradas nos IR de alguns em parâmetros de hemograma em adultos brasileirosnbsp; reafirmam a importância de se ter padrões de referência laborarias próprios. Os resultados podem subsidiar a interpretação mais precisa dos exames, identificação adequada e a prevenção de doenças no Brasil.
