Resumo Os sabonetes têm um papel importante para a nossa higiene e saúde, pois eles além de ter efeito bactericida, também removem as sujeiras presentes no corpo humano. Avaliar a eficácia de sabonetes com atividade antimicrobiana de diferentes marcas comerciais vendidas no Brasil. Foram realizados ensaios da atividade antimicrobiana dos diferentes sabonetes através do método difusão em ágar frente aos microrganismos Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae, Acinetobacter baumannii, Proteus mirabilis e Candida albicans. Todos os sabonetes comerciais testados apresentaram formação de halo de inibição antimicrobiana frente às bactérias S. aureus e P. aeruginosa. Apenas dois sabonetes comerciais apresentaram inibição das espécies A. baumannii e C. albicans. Nenhum dos sete produtos estudados apresentou inibição das bactérias E. cloacae, P. mirabilis e E. coli. Na comparação das informações contidas nas embalagens dos produtos com os resultados obtidos durante a pesquisa realizada foram observadas divergências. Os sabonetes que apresentaram maior eficiência contra os microrganismos testados foram aqueles das apresentações 1 e 2, que se mostraram eficazes contra as espécies de bactérias S. aureus, P. aeruginosa e A. baumannii e contra a espécie de fungo C. albicans. As marcas 3, 4, 5, 6 e 7 apresentaram o mesmo resultado de sensibilidade frente as bactérias das espécies S. aureus e P. aeruginosa, com variação quantitativa apenas do halo de inibição. Houve divergência entre as informações contidas nas embalagens dos sete produtos em estudo e os resultados dos testes experimentais.

Abstract Soaps play an important role in our hygiene and health, as they not only have a bactericidal effect but also remove dirt from the human body. To evaluate the effectiveness of soaps with antimicrobial activity from different commercial brands sold in Brazil. Tests of the antimicrobial activity of different soaps were carried out through diffusion in agar against the microorganisms Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Enterobacter cloacae, Acinetobacter baumannii, Proteus mirabilis, and Candida albicans. All commercial soaps tested transfer antimicrobial inhibition halo formation against S. aureus and P. aeruginosa bacteria. Only two commercial soaps inhibit the species A. baumannii and C. albicans. None of the seven products studied showed inhibition of E. cloacae, P. mirabilis, and E. coli bacteria. When comparing the information contained in the packaging of the products with the results obtained during a survey, divergences were observed. The soaps that provide greater efficiency against the tested microorganisms were presented in presentations 1 and 2, which become useful against the bacteria species S. aureus, P. aeruginosa, and A. baumannii and a fungus species C. albicans. Marks 3, 4, 5, 6, and 7 parallel the same sensitivity result opposite as bacteria of the species S. aureus and P. aeruginosa, with quantitative variation only of the inhibition halo. There was a divergence between the information contained in the packaging of the seven products under study and the results of the experimental tests.

Abstract This article aims to estimate the prevalence of musculoskeletal disorders (MD) on the adult population of Campinas, São Paulo, Brazil, verifying associated demographic and socioeconomic factors, and to analyze their impact on Health-Related Quality of Life (HRQoL) according to sex. A population-based study was conducted with 2,166 individuals using data from the ISACamp 2014/15. The Medical Outcomes Study SF-36-Item Short Form Health Survey (SF-36) was used to measure HRQoL according to MD. Prevalence ratios (PR) were estimated by Poisson regression. Musculoskeletal disorders had a prevalence of 8.5% (6.7% tendonitis and 2.7% work-related musculoskeletal disorders - WMSD). Results showed a higher prevalence of musculoskeletal disorders in women, active or on leave due to illness, and in individuals with higher education levels. Moreover, reduced HRQoL scores were observed in 6 of the 8 domains, due to MD. The mental component and physical component showed greater impairment respectively among women and men after self-reported WMSD. These findings point to substantial damage from musculoskeletal disorders on the population’s HRQoL. WMSD affect the HRQoL of men and women distinctly.

Resumo O objetivo deste artigo é estimar a prevalência de doenças musculoesqueléticas (DM) na população adulta de Campinas/SP, Brasil, verificar fatores demográficos e socioeconômicos associados e analisar o seu impacto na qualidade de vida relacionada à saúde (QVRS) segundo sexo. Este é um estudo de base populacional utilizando dados do ISACamp 2014/15, com 2.166 indivíduos. Para a medida de QVRS, foram calculados os escores médios do Short Form Health Survey 36 (SF-36) segundo as DM e utilizada a regressão de Poisson para estimar as razões de prevalência (RP). A prevalência de DM foi de 8,5% (6,7% de tendinite e 2,7% de doenças osteomusculares relacionadas ao trabalho - DORT). Os resultados deste estudo mostraram maior prevalência de DM em mulheres, na população adulta ativa ou afastada por doença e em indivíduos com maior escolaridade. Além disso, observou-se redução nos escores de QVRS, devido às DM, em quase todos os domínios do instrumento. O maior comprometimento foi observado no componente mental entre as mulheres, e no componente físico, entre os homens, após autorrelato de DORT. Os achados mostram o impacto substancial das DM na QVRS da população. As DORT afetam distintamente a QVRS de homens e mulheres.

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.

RESUMO A produção de suínos confinados gera efluentes que quando aplicados no solo servem como fonte de fertilizante e quando aplicados sem tratamento adequado alteram a qualidade ambiental. Estes dejetos contêm elementos potenciais contaminantes cuja aplicação excessiva gera acúmulo de materiais e podem ocasionar efeitos tóxicos para as plantas, como na germinação de sementes. Neste estudo objetivou-se analisar o efeito de doses de dejetos líquidos de suínos (DLS) sobre a germinação de três culturas de grãos de interesse agrícola. Os ensaios foram realizados em condições de laboratório com sementes de soja, trigo e milho, que foram dispostas em placas de Petri, na quantidade de dez sementes por placa. Foram aplicadas doses tratamentos de DLS, caracterizado quimicamente, correspondentes a 0, 1,4 e 2,1 xDP (vezes a Dose Padrão) m³ ha-1 com três repetições. As placas foram colocadas na BOD em temperatura 24 0C. Os dados obtidos foram analisados pelo teste de Tukey (5%). Aos sete dias do início do ensaio foi determinada a porcentagem de germinação. O DLS possui em sua composição alguns elementos potenciais contaminantes, como o cobre, o zinco e o amônio, os quais podem ocasionar prejuízos na germinação de diversas culturas, sobretudo com exposição direta das sementes nas placas de Petri. As sementes de soja e trigo sofreram efeito negativo da aplicação de DLS apresentando redução na taxa de germinação com o uso de 1,4 e 2,1 xDP m³ ha-1. A aplicação do equivalente a 1,4 e 2,1 xDP m³ ha-1 de DLS não afetaram significativamente a germinação de sementes de milho.

ABSTRACT Pig production generates effluents that, when applied to the soil, serve as a source of fertilizer and, when applied without adequate treatment, alter the environmental quality. These wastes contain potential contaminating elements whose excessive application generates an accumulation of materials and can cause toxic effects for plants, such as seed germination. This study aimed to analyze the effect of doses of pig slurry (SP) on seed germination of three grain crops of agricultural interest. The assays were carried out under laboratory conditions with soybean, wheat, and corn seeds placed in Petri dishes, with ten seeds per dish. SP doses/treatments, chemically characterized, corresponding to 0, 1,4, and 2,1 tSD (times the Standard Dose) m³ ha-1 were applied with three replicates. The plates were placed in the BOD at temperature 24°C. The data obtained were analyzed using the Tukey test (5%). Seven days from the beginning of the trial, the percentage of germination was determined. SP has in its composition some potential contaminating elements, such as copper, zinc, and ammonium, which can cause damage to the germination of several cultures, especially with direct exposure of the seeds in Petri dishes. Soybean and wheat seeds were significantly affected by the application of SP, showing a reduction in the germination rate with the use of 100 and 150 m³ ha-1. The application of the equivalent of 1,4, and 2,1 tSD m³ ha-1 of SP did not significantly affect the germination of maize seeds.

ABSTRACT Purpose: To evaluate the in vivo efficiency of commercial polymeric membranes for guided bone regeneration. Methods: Rat calvarial critical size defects was treated with LuminaCoat (LC), Surgitime PTFE (SP), GenDerm (GD), Pratix (PR), Techgraft (TG) or control (C-) and histomorphometric analysis determined the percentage of new bone, connective tissue and biomaterial at 1 or 3 months. Statistical analysis used ANOVA with Tukey’s post-test for means at same experimental time and the paired Student’s t test between the two periods, considering p < 0.05. Results: New bone at 1 month was higher for SP, TG and C-, at 3 months there were no differences, and between 1 and 3 months PR had greater increase growthing. Connective tissue at 1 month was higher for C-, at 3 months for PR, TG and C-, and between 1 and 3 months C- had sharp decline. Biomaterial at 1 month was higher for LC, in 3 months for SP and TG, and between 1 and 3 months, LC, GD and TG had more decreasing mean. Conclusions: SP had greater osteopromotive capacity and limitation of connective ingrowth, but did not exhibit degradation. PR and TG had favorable osteopromotion, LC less connective tissue and GD more accelerated biodegradation.

ABSTRACT Protein quality is related to amino acid composition and digestibility. Accurate evaluation of apparent digestibility coefficients (ADCs) of nutrients in commonly used feedstuffs is paramount for formulating efficient aquafeed. ADCs of soybean meal (SBM) and poultry by-product meal (PBM) were evaluated using reference diets formulated with two types of ingredients (semi-purified [SP] and practical [P]) for juvenile Nile tilapia ( Oreochromis niloticus, Linnaeus) of the GIFT strain. Groups of 20 juveniles (65.05 ± 12.37 g) were fed twice a day to apparent satiety with one of the four experimental diets (SBM-SP, SBM-P, PBM-SP, and PBM-P) in quadruplicate for 30 days. After the last feeding, feces were collected by siphoning hourly and the ADCs of dry matter, protein, and amino acids (AAs) were calculated. Nile tilapia exhibited a high capacity to digest SBM and PBM, with most ADCs exceeding 90 %. The type of reference diet affected the ADCs of protein and AAs on the test ingredients, with the SP reference diet providing the highest ADC, mainly in SBM. Digestibility data generated with a P-type reference diet demonstrated more practical relevance than those generated with an SP-type reference diet. They can be applied in digestibility studies for Nile tilapia.

Abstract Objective To analyze the effects of hospital cardiorespiratory physical therapy protocol on the functional capacity and quality of life of patients submitted to hematopoietic stem cell transplantation (HSCT). Methods From January to December 2019, bilateral dynamometry, Manovacuometry and Ventilometry, peak expiratory flow "Peak Flow", 6-min walk test (6MWT), SF-36 Quality of Life Questionnaire and Visual Analog Scale (VAS) were applied in patients who have undergone an allogeneic or autologous hematopoietic stem cell transplantation (HSCT), pre-conditioning (initial evaluation) and pre-discharge (final evaluation). The patients were submitted to an intervention protocol, consisting of aerobic training, muscle strengthening and respiratory muscle training, between the two assessments. Results 29 patients were enrolled in the study and 24 (83%) completed all procedure. Myeloablative and reduced intensity conditioning were performed in 89.6% and 10.4%, respectively; 17 (58%) patients have undergone an autologous HSCT; 10 (35%) identical related allogeneic HSCT, and 2 (7%) haploidentical allogeneic HSCT. The median number of interventions per patient was 3 (1-9). A decreasing in the right and left dynamometry (p ≤ 0.0001 and 0.002, respectively) and, also in the distance covered in the 6MWT (p = 0.004), was observed after HSCT. There was no significant difference in respiratory muscle strength, quality of life and fatigue sensation. Conclusion Cardiorespiratory rehabilitation can preserve functional capacity and quality of life.

ABSTRACT Purpose: To investigate the effects of chronic stress in the prostate of prepubertal and adult rats. Methods: Thirty-two male rats were assigned into four groups depending on the type of treatment (control or stressed) and the age at which stress was initiated (prepubertal or adult). Restraint stress stimuli were applied for six weeks. Stressed prepubertal and adult rats evaluated immediately after the last stress stimuli were named SP and SA groups, respectively. Age-matched rats were used as control groups (CP and CA). At the end of the experiment, the rats were euthanized, and prostate morphological parameters were evaluated and statistically compared. Results: Application of stress stimuli to the SP group resulted in reduced body weight, but no prostate morphological modification was noted. The SA group showed reduced testosterone level and prostatic epithelium surface density, in comparison to CA group. Further, the prostatic lumen surface density was increased in adult stressed animals, in comparison to adult controls. Conclusions: The stress stimuli promoted changes in hormonal and morphological parameters in the prostate of adult stressed rats. Prepubertal stressed animals did not presented modifications of prostate morphology.

Abstract The objective of this work was to estimate genetic parameters and to select lines of carioca commercial bean group with high yield, great 100-seed weight, good grain appearance, and good resistance to fusarium wilt, disease caused by the fungus Fusarium oxysporum f. sp. phaseoli that inhabits the soil. A total of 114 lines coming from two populations were evaluated together with seven control genotypes in the winter crop season in the years/generations of 2015/F5:7 and 2016/F5:8. There is a genetic variability among the carioca common bean (Phaseolus vulgaris) lines for all the traits evaluated, and the estimates of the genetic parameters show a possible successful selection for reaction to fusarium wilt, yield, grain appearance, and 100-seed weight. Twenty-four lines of carioca common bean that were selected combine high resistance to fusarium wilt, yield, 100-seed weight, and good grain appearance. CNFC 19126, CNFC 19205, and CNFC 19131 show a better performance than the control genotypes with the highest level of resistance, so their evaluation in multiple environments is recommended, aiming at new resistant cultivars to Fusarium oxysporum f. sp. phaseoli.

Resumo O objetivo deste trabalho foi estimar parâmetros genéticos e selecionar linhagens de grupo de feijão comercial carioca com alta produtividade, grande massa de 100 grãos, bom aspecto visual dos grãos e boa resistentência à murcha-de-fusário, doença causada pelo fungo Fusarium oxysporum f. sp. phaseoli que habita o solo. Um total de 114 linhagens obtidas de duas populações foram avaliadas juntamente com sete genótipos controles na safra de inverno nos anos/gerações de 2015/F5:7 e 2016/F5:8. Há variabilidade genética entre as linhagens de feijão carioca (Phaseolus vulgaris) para todos os caracteres avaliados, e as estimativas de parâmetros genéticos mostram uma possível seleção bem-sucedida para reação à murcha-de-fusário, produtividade, aparência dos grãos e massa de 100 grãos. Vinte e quatro linhagens de feijão carioca que foram selecionadas combinam alta resistência à murcha-de-fusário, produtividade, massa de 100 grãos e boa aparência. CNFC 19126, CNFC 19205 e CNFC 19131 destacaram-se porque eles apresentam um melhor desempenho que os genótipos de controle com o maior nível de resistência, portanto sua avaliação em vários ambientes é recomendada, visando a novas cultivares resistentes a Fusarium oxysporum f. sp. phaseoli.

Resumo Trachemys dorbigni é a espécie de tartaruga de água doce mais abundante do Rio Grande do Sul, no Sul do Brasil. Sabe-se que os quelônios são hospedeiros de uma grande variedade de patógenos, incluindo vírus, bactérias, hemoparasitos e helmintos. Dentre estes, oito gêneros de Polystomatidae (Platyhelminthes: Monogenoidea) infectam tartarugas de água doce: Apaloneotrema, Aussietrema, Fornixtrema, Manotrema, Pleurodirotrema, Polystomoidella, Polystomoides, Uropolystomoides e Uteropolystomoides. No entanto, pouco ainda se sabe sobre a biologia destes parasitos na Região Neotropical. Durante uma citoscopia investigativa, foram observados espécimes de Polystomatidae localizados no interior da bexiga urinária de T. dorbigni. Os espécimes coletados foram fixados e corados para identificação taxonômica. No presente artigo, uma nova espécie de Polystomoides (Monogenoidea: Polystomatidae) parasitando a bexiga urinária de tartaruga de água doce da espécie T. dorbigni no Brasil é descrita. Polystomoides santamariensis n. sp. difere das demais espécies no tamanho dos espinhos genitais, que são maiores. Devido a enorme diversidade de tartarugas de água doce ao redor do mundo, é provável que um grande número de polistomatídeos de quelônios ainda seja desconhecido.

Abstract Trachemys dorbigni is the most abundant freshwater turtle species in Rio Grande do Sul, southern Brazil. Chelonians are known to host a wide variety of pathogens, including viruses, bacteria, hemoparasites and helminths. Among these, nine genera of polystomatid flatworms (Monogenoidea; Polystomatidae) infect freshwater turtles: Apaloneotrema, Aussietrema, Fornixtrema, Manotrema, Pleurodirotrema, Polystomoidella, Polystomoides, Uropolystomoides and Uteropolystomoides. However, little is known about the biology of these parasites in the Neotropical Realm. Through investigative cystoscopy, specimens of Polystomatidae were located inside the urinary bladder of the host T. dorbigni. Retrieved specimens were fixed and stained whole mounts prepared for taxonomic identification. In the present paper, a new species of Polystomoides (Monogenoidea: Polystomatidae) parasitizing the urinary bladder of a freshwater turtle of the species T. dorbigni in Brazil is described. Polystomoides santamariensis n. sp. differs from the congeneric species on the length of the genital spines, which are longer. Given the enormous diversity of freshwater turtles around the world, it is likely that a large number of chelonian polystomatids are still unknown.

Resumo Este estudo teve como objetivo investigar o efeito da ativação ultrassônica (AU) de três cimentos endodônticos na resistência de união à dentina radicular e na qualidade da obturação do canal radicular. Noventa e seis incisivos bovinos foram instrumentados e a obturação dos canais radiculares foi realizada com AH Plus (AP), Sealer Plus (SP) ou Sealer Plus BC (BC), com ou sem AU (n=16/grupo). Duas fatias de 1,5 mm foram obtidas de cada terço radicular. A primeira fatia foi submetida ao teste push-out e análise de modo de falha, enquanto a segunda foi observada em um estereomicroscópio para avaliação da qualidade da obturação. Os dados foram analisados por testes de Kruskal-Wallis, Mann-Whitney e Friedman (α=0,05). SP mostrou maior resistência de união e menos espaços vazios na massa obturadora do que BC no terço apical e quando os dados dos terços radiculares foram agrupados. SP também apresentou maior resistência de união em comparação ao AH Plus no terço apical. A AU melhorou a resistência de união quando BC foi usado, mas não afetou a qualidade da obturação de nenhum dos cimentos. Não houve diferença significante entre os cimentos ativados por ultrassom em relação à resistência de união e qualidade da obturação. Quando comparados os terços radiculares, a resistência de união foi semelhante ao longo da raiz, mas houve uma tendência de pior qualidade no preenchimento, com mais vazios, no terço apical. Concluindo, a AU foi eficaz em aumentar a resistência de união do cimento à base de silicato de cálcio, mas não melhorou a qualidade da obturação. Para os cimentos à base de resina epóxi, essas propriedades não foram afetadas pela AU.

Abstract This study aimed to investigate the effect of ultrasonic activation (UA) of three endodontic sealers on the bond strength to root dentin and root canal filling quality. Ninety six bovine incisors were instrumented and root canal filling was carried out using AH Plus (AP), Sealer Plus (SP), or Sealer Plus BC (BC), with or without UA (n=16/group). Two 1.5-mm slices were obtained from each root third. The first slice was subjected to push-out testing and failure mode analysis, while the second was observed under a stereomicroscope for filling quality assessment. Data were analyzed by Kruskal-Wallis, Mann-Whitney and Friedman tests (α=0.05). SP showed higher bond strength and fewer voids than BC in the apical third and when root thirds data were pooled. SP also had higher bond strength compared with AH Plus in the apical third. UA improved the bond strength when BC was used but did not affect the filling quality of any sealer. There were no significant differences between the ultrasonically activated sealers regarding bond strength and filling quality. When root thirds were compared, the bond strength was similar along the root, but there was a tendency to worsen filling quality, with more voids, in the apical segment. In conclusion, UA was effective in increasing the bond strength of the calcium silicate-based sealer but did not improve its filling quality. For the epoxy resin-based sealers, these properties were not affected by UA.

ABSTRACT Many students dislike Physical Education classes in Brazil because of content repetition, unsatisfactory curricular organization, among other factors. The purpose of this study is to assess the efficiency of a proposal for Physical Education classes, which includes contents of physical activities and the use of comic books application. This is a qualitative study, which comprises both bibliographic and field researches. Twelve classes were held to a group of eight graders from a public school in the city of Piracicaba/SP/Brazil. Questionnaires were used to evaluate the proposal for Physical Education classes. We found out that the use of comic books application is an effective teaching resource, as it reveals the students’ experiences, what they felt, and the mediation between their “rational” and “sensitive” knowledge about physical activities. There is evidence that our experience has provided participating students with: 1- Leisure education and health education, 2- Awakening to knowledge of the body culture of movement, 3- Access to some leisure contents, mainly those related to physical, sports and artistic ones, 4- The creation of comics by App Flaras.

Abstract The lungs have great importance in patients with paracoccidioidomycosis since they are the portal of entry for the infecting fungi, the site of quiescent foci, and one of the most frequently affected organs. Although they have been the subject of many studies with different approaches, the severity classification of the pulmonary involvement, using imaging procedures, has not been carried out yet. This study aimed to classify the active and the residual pulmonary damage using radiographic and tomographic evaluations, according to the area involved and types of lesions.

Resumo Em todo o mundo, existem evidências acumuladas da intensificação de ondas de calor devido às mudanças climáticas. As diferenças regionais nos efeitos das ondas de calor requerem estudos locais para a implementação de estratégias públicas de mitigação e adaptação. Este trabalho analisa e caracteriza a ocorrência de ondas de calor para a cidade de Campinas, Brasil, por meio de um estudo observacional de 1956 a 2018. A definição de ondas de calor adotada requer que as temperaturas máximas e mínimas diárias estejam acima dos limites diários derivados da normal climática 1961-1990. As métricas anuais e sazonais de número, frequência e duração de ondas de calor mostraram tendências significativas e positivas, exceto no inverno. Verificou-se que os eventos mais longos, mais intensos e mais frequentes ocorreram nos últimos 20 anos e que uma mudança significativa de tendência ocorreu no início da década de 1980. Por fim, realizou-se um estudo exploratório da variabilidade intra-urbana, comparando-se as métricas de duas estações meteorológicas distantes 30 km entre si, em Campinas. Foram encontrados padrões de métricas semelhantes para as duas estações meteorológicas, com eventos de ondas de calor mais prolongados e frequentes para a estação localizada na região com maior taxa de ocupação do solo.

Abstract Worldwide there is accumulated evidence of heatwave intensification due to climate change. Regional differences in the effects of heatwaves require local studies to implement public mitigation and adaptation strategies. This work analyzes and characterizes heatwaves’ occurrence for the city of Campinas, Brazil, through an observational study from 1956 to 2018. The definition of heatwaves adopted requires that the maximum and minimum daily temperatures be above the daily limits derived from climate normal 1961-1990. The annual and seasonal metrics of the number, frequency, and heatwaves’ duration showed significant and positive trends, except in winter. We found that the longest, the more intense, and the most frequent events occurred in the last 20 years and that a significant change in trend occurred at the beginning of the 1980s. Lastly, we performed an exploratory study of intra-urban variability, comparing heatwave metrics between two different weather stations that are 30 km apart in the city of Campinas. We found similar metrics patterns for the two weather stations, with more prolonged and more frequent heatwave events for the region's station with a higher rate of urban land occupation.
