ABSTRACT Constant changes during the seed maturation process affect its final quality and the post-harvest fruit resting, which can improve seed physiological quality. Therefore, the objective of this study was to evaluate the physiological and enzymatic activities of eggplant seeds extracted from fruits harvested at different ages and resting periods after harvest. Fruits were harvested presenting different colors at 40, 50, 60, and 70 days after anthesis (DAA) and rested for 0 (freshly harvested fruits), 10, and 20 days. The experimental design was set as completely randomized, with four replications and evaluated seeds extracted from six fruits per plot. The resting periods in eggplant fruits harvested at less than 60 DAA improved the mass of 1000 seeds, germination, vigor, and protein content. Seeds with higher germination and vigor presented lower dismutase (SOD), catalase (CAT), and peroxidase (POX) enzymatic activity. The results indicated that the ideal moment of eggplant harvest for seed production is when the fruit reaches the yellowish-brown color corresponding to about 60 DAA; however, if the eggplant fruit is harvested earlier (40 or 50 DAA), it has to rest for about 10 to 20 days to achieve high physiological quality (germination and vigor).

RESUMO Mudanças constantes durante o processo de maturação das sementes afetam sua qualidade final, assim como o repouso pós colheita dos frutos pode melhorar a qualidade fisiológica das sementes. O objetivo deste estudo foi avaliar a qualidade fisiológica e a atividade enzimática de sementes de berinjela provenientes de frutos com diferentes idades e períodos de repouso após a colheita. Os frutos foram colhidos apresentando cores diferentes aos 40, 50, 60 e 70 dias após a antese (DAA) e mantidos em repouso por 0 (frutos recém-colhidos), 10 e 20 dias. Foi utilizado delineamento experimental inteiramente ao acaso, com quatro repetições e foram avaliadas as sementes extraídas de seis frutos por parcela. O repouso dos frutos de berinjela colhidos com menos de 60 DAA possibilitou maiores massas de 1000 sementes, germinação, vigor e teor de proteínas das sementes. As sementes com maior germinação e vigor apresentaram baixa atividade enzimática da superóxido dismutase (SOD), catalase (CAT) e peroxidase (POX). Os resultados indicaram que o momento ideal da colheita é quando o fruto atinge a cor amarelada-marrom correspondente a cerca de 60 DAA; no entanto, se o fruto de berinjela for colhido precocemente (40 a 50 DAA), ele tem que permanecer em repouso por cerca de 10 a 20 dias para as sementes alcançarem alta qualidade fisiológica (germinação e vigor).

Abstract The prevalence of impaction of the permanent canine on the cleft side (PCCS) ranges from 12-35% after alveolar bone grafting (ABG). PCCSs usually develop above other permanent teeth in the alveolar process, gradually becoming vertical until they reach the occlusal plane. The type of cleft, hypodontia of lateral incisor on the cleft side, slower PCCS root development, and genetic factors are predictors of impaction and/or its ectopic eruption. Objective: To compare the behavior of PCCS in individuals with complete unilateral cleft lip and palate (UCLP) subjected to secondary alveolar grafting (SAG) with different materials. Methodology: This retrospective longitudinal study analyzed 120 individuals undergoing SAG with iliac crest bone, rhBMP-2, and mandibular symphysis. The individuals were selected at a single center and equally divided into three groups. Panoramic radiographs were analyzed by the Dolphin Imaging 11.95 software to measure PCCS angulation and PCCS height from the occlusal plane at two different timepoints. Results: No statistical significance was found between grafting materials (P=0.416). At T1, the PCCS height from the occlusal plane was greater for rhBMP-2 and mandibular symphysis compared to iliac crest bone. The lateral incisor on the cleft side was not related to success or lack of eruption of PCCS (P=0.870). Conclusion: Impaction rates of PCCS were similar for the materials studied. Absence of the lateral incisor on the cleft side did not prevent spontaneous eruption of PCCSs.

Abstract Introduction Oral carcinoma has been reported at a substantial proportion in patients who never smoke and never drink. However, the proportion may vary by subsite and ethnicity. Objective We aimed to determine the clinicopathological features of buccal squamous cell carcinoma (SCC) in a Japanese population. Methods We retrospectively analyzed the records of patients diagnosed with buccal SCC at our institution from September 2002 to November 2015. We reviewed the gender, age, tumor status, treatment, smoking, alcohol drinking, multiple primary cancers, and prognosis of the patients. The overall and cause-specific survival rates were calculated, and the effects of clinicopathological variables were assessed by univariate analysis. Furthermore, the cause of death was evaluated. Results Among the 63 patients (men: 38; women: 25) included in the present study, 29 (46.0%) never smoked or drank. Women were almost 5 years older than men (p = 0.014). The number of women in the group who never smoked or drank was disproportionately higher than that of those in the smoker or drinker groups (p < 0.001). In total, 29 patients (46.0%) had 59 multiple primary cancers, including 26 oral cancers. Surgeries and radiotherapy were performed in 57 (90.5%) and 6 (9.5%) cases, respectively. The 5-year overall survival and disease-specific survival rates were 74.6 and 78.8%, respectively. Conclusion Our study confirms that buccal SCC may develop in older adult Japanese patients, especially in women who have never smoked or drank. These patients could be at risk for second primary malignancy.

Objective: To analyze the association between parental supervision characteristics and different bullying roles among Brazilian school adolescents. Methods: Cross-sectional study that used data from the National School Health Survey (PeNSE) 2015. Frequent meals with parents/guardians, knowledge about free time, and checking homework were the parental practices assessed. Logistic regression was used for association between 4 these practices and bullying (perpetration and victimization), presented as oddsratio (OR) and 95% confidence intervals (95%CI). Results: Among 102,072 school adolescents, frequent meals with parents or guardians [ORvitim=0.86 (95%CI 0.84;0.89); ORperp=0.85 (95%CI 0.82;0.88)], checking homework [ORvitim=0.95 (95%CI 0.92;0.97); ORperp=0.76 (95%CI:0.74;0.78)], and parents or guardian’s knowledge of students’ free time [ORperp=0.70 (95%CI 0.68;0.73] were inversely associated with bullying. Conclusion: Greater parental supervision reduced the chance of victimization and perpetration bullying among adolescents.

ABSTRACT Purpose: Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown. Thus, the aim of this study was to evaluate single- and double-stranded sperm DNA fragmentation, and oxidative-induced sperm DNA damage in men with varicocele. Materials and Methods: A cross-sectional study was performed, including 94 normozoospermic adults, of which 39 men without varicocele (controls) and 55 men with varicocele grades II or III, uni- or bilaterally. All men collected semen by masturbation. After semen analysis, the remaining volume was used for evaluation of three types of sperm DNA damage: (i) total DNA fragmentation, using an alkaline comet assay, (ii) double-stranded DNA fragmentation, using a neutral comet assay, and (iii) oxidative DNA damage, using an alkaline comet assay associated with the DNA glycosylase formamidopyrimidine enzyme. In each assay, percentage of sperm with any degree of DNA fragmentation, and with high DNA fragmentation were compared between the groups using an unpaired Student's t test or a Mann-Whitney test. Results: The varicocele group presented a higher rate of sperm with fragmented DNA (both any and high DNA fragmentation), considering single-stranded DNA fragmentation, double-stranded DNA fragmentation, or a combination of both, as well as oxidative- induced DNA fragmentation. Conclusions: Patients with varicocele have an increase in sperm DNA fragmentation levels, particularly in oxidative stress-induced sperm DNA damage.

Abstract During times of increasingly recognized importance of interprofessional practices, professionals in Medicine, Dentistry, and Speech Pathology areas cooperate to optimize treatment of velopharyngeal dysfunction (VPD), after primary palatoplasty for correction of cleft palate. Objective Our study aims to compare velar length, velar thickness, and depth of the nasopharynx of patients with unilateral cleft lip and palate (UCLP) with the presence, or absence, of hypernasality and nasal air emission; and to verify if the depth:length ratio, between nasopharynx and velum, would be predictive of consistent hypernasality and nasal air emission (speech signs of VPD). Methodology Cephalometric radiographs and outcome of speech assessment were obtained from 429 individuals, between 6 and 9 years of age, with repaired unilateral cleft lip and palate. Velar length, velar thickness, depth of the nasopharynx, depth:length ratio, scores of hypernasality, and scores of nasal air emission were studied and compared; grouping the radiographs according to presence or absence of hypernasality and nasal air emission. Results For the group with speech signs of velopharyngeal dysfunction (those with consistent hypernasality and nasal air emission), the velums were shorter and thinner; the nasopharynx was deeper and the depth:length ratio was larger than the group without hypernasality and nasal air emission. Velar length was significantly shorter in individuals with consistent hypernasality and nasal air emission (p<0.001) and with history of palatal fistula (p=0.032). Depth of nasopharynx was significantly greater in individuals with consistent hypernasality and nasal air emission (p<0.001). Depthlength ratio was significantly larger in individuals with consistent hypernasality and nasal air emission (p<0.001). A depth:length ratio larger than 0.93 was always associated with speech signs of VPD. Conclusion Estimated with cephalometric radiographs, a depth:length ratio greater than 0.93, between the nasopharyngeal space and the velum, was 100% accurate in predicting hypernasality and nasal air emission after primary repair of unilateral cleft lip and palate.

RESUMO Objetivo: Descrever os custos e resultados da facoemulsificação na cirurgia de catarata realizada por médicos residentes de oftalmologia. Métodos: Foram obtidos prontuários médicos de pacientes operados em 2011 por residentes do terceiro ano (R3) usando facoemulsificação (n=576). Nossa estimativa de despesas incluiu os custos profissionais e hospitalares (taxas, materiais, medicamentos e equipamentos). Os desfechos do estudo incluíram acuidade visual corrigida por óculos pré-operatória e 6 meses após a cirurgia, taxa de complicações intraoperatórias e número total de visitas pós-operatórias. Nós comparamos as variáveis de resultados com procedimentos extracapsulares de extração de catarata (n=274) realizados por residentes R3 em 1997. Resultados: O custo médio da facoemulsificação foi US$ 416, enquanto uma estimativa geral indicou o custo da extração de catarata extracapsular seria de US$ 284 (em 3 de dezembro de 2011). A acuidade visual corrigida por óculos média pré-operatória foi pior na extração de catarata extracapsular (1,73 ± 0,62 logMAR) do que na facoemulsificação (0,74 ± 0,54, p<0,01); a acuidade visual corrigida por óculos média pós-operatória foi melhor na facoemulsificação (0,21 ± 0,36 logMAR) do que na extração de catarata extracapsular (0,63 à facoemulsificação (85%) atingiram acuidade visual corrigida 45% daqueles submetidos à extrações extracapsulares de catarata obtiveram a mesma acuidade visual pós-operatória (p<0,01). A taxa de complicações intraoperatórias foi significativamente maior após extrações de catarata extracapsular (21%) do que após as facoemulsificações (7,6%) (p<0,01) e o número médio de consultas pós-operatórias também foi maior após extração de catarata extracapsular (5,6 ± 2,3) do que após facoemulsificações (4,5 ± 2,4) (p<0,01). Conclusão: Esses dados indicam que a cirurgia de catarata realizada por oftalmologistas em treinamento utilizando facoemulsificação é dispendiosa, mas comparada aos resultados da extração de catarata extracapsular, o ensino da facoemulsificação leva a uma taxa de complicações aproximadamente 3 vezes menor, menor número de consultas pós-operatórias e, mais importante, melhor acuidade visual.

ABSTRACT Purpose: To describe costs and outcomes of phacoemulsification for cataracts performed by ophthalmology residents. Methods: We obtained medical records from patients operated on in 2011 by third year residents (R3) using phacoemulsification (n=576). Our expenses estimation included professionals’ and hospital costs (fees, materials, medications, and equipment). The study outcomes included spectacle-corrected visual acuities before and six months after the operation, rate of intraoperative complications, and total number of postoperative visits. We compared outcome variables with those from extracapsular cataract extraction procedures (n=274) performed by R3 residents in 1997. Results: The mean total cost for phacoemulsification was US$ 416, while an overall estimation indicated the extracapsular cataract extraction cost at US$ 284 (as of December 30, 2011). The mean preoperative spectacle-corrected visual acuity was worse for eyes scheduled for extracapsular cataract extraction (1.73 ± 0.62), than for eyes scheduled for phacoemulsification (0.74 ± 0.54 logMAR) (p<0.01); the mean postoperative visual acuity was better for phacoemulsification (0.21 ± 0.36 logMAR), than for extracapsular cataract extraction (0.63 ± 0.63 logMAR) (p<0.01). Most patients undergoing phacoemulsification (85%) achieved postoperative spectacle-corrected visual acuities ≥0.30 logMAR, while only 45% of those undergoing extracapsular cataract extractions achieved the same postoperative visual acuity (p<0.01). The rate of intraoperative complications was significantly higher after extracapsular cataract extractions (21%) than it was after phacoemulsifications (7.6%) (p<0.01), and the mean number of postoperative visits was also higher after extracapsular cataract extractions (5.6 ± 2.3) than after phacoemulsifications (4.5 ± 2.4) (p<0.01). Conclusion: These data indicate that cataract surgery performed by in-training ophthalmologists using phacoemulsification is expensive, but compared to extracapsular cataract extraction results, teaching phacoemulsification leads to an approximate three-fold lower complication rate, smaller number of postoperative visits and, most importantly, better visual acuities.

ABSTRACT The objective with this study was to evaluate the liver histology and hematological parameters of female Rhamdia quelen fed diets supplemented with different oils: 5% marine fish oil, 5% refined palm oil, 5% soybean oil, and a combination of the three. The lipid vacuolization (steatosis) in the liver was analyzed according to a score of vacuolization when: 0 = absence, 1 = reduced, 2 = intermediate, and 3 = intense. At the end of the experiment, females (n = 10) were selected from each treatment (two per cage), and the blood was collected for erythrocyte and biochemical analysis. Lower vacuolization indices in the liver were observed at the beginning of the experiment. However, with time, the presence of vacuoles was more evident but presented similar morphology among all treatments. The blood parameters were also not influenced by the different diets, except for glucose levels, which was higher in the treatment with the mixture of oils. The absence of differences regarding liver morphology (steatosis) and hematological parameters indicates that the replacement of fish oil by vegetable oils could be performed without damage to the health of R. quelen females.

OBJECTIVES: Quality improvement (QI) initiatives based on data from international registries have been reported previously; however, there is a lack of information on the impact on the costs of medical care associated with the use of these tools. METHODS: Patients admitted due to myocardial infarction (MI), included in the ACTION Registry® and CathPCI Registry®, in a private Brazilian hospital (i.e., the reference hospital) were analyzed. The costs of care of these patients were compared to the costs of MI admissions in nine similar hospitals not included in the same QI program. Regression models were used to analyze the cost change over time between the two groups of hospitals. Readmission rates were compared using logistic regression, adjusting for the same variables as in the cost model. RESULTS: Overall, the annual medical cost inflation in Brazil was higher than the annual cost trend in the reference hospital during the period of analysis. Moreover, the annual in-hospital costs indicate that the reference hospital has a statistically significant 6% lower cost trend for patients with acute MI, compared to patients with the same diagnostic code in the comparison hospitals group, in an adjusted analysis (p-value=0.041). Using multivariable analysis, the readmission rates were also found to be significantly lower in the reference hospital than in the comparison hospitals, with an odds ratio of 0.68 (p-value=0.042). CONCLUSION: The use of the NCDR® as a benchmark to guide QI programs outside the United States was associated with the positive impact of bending the cost curve to below that of national medical inflation and the comparison hospitals’ costs, with a lower incidence of hospital readmission.

O catador de materiais recicláveis é excluído pelo tipo de atividade que realiza, em condições inadequadas e sem reconhecimento social. O objetivo desta pesquisa foi compreender o processo saúde-doença-cuidado de pessoas que trabalham com reciclagem para auxiliar na formação de estratégias de acolhimento dessa população na Atenção Primária. Trata-se de um estudo exploratório descritivo de base qualitativa, tendo sido realizadas oito entrevistas com trabalhadores da reciclagem e análise hermenêutica gadameriana. A análise evidenciou três grandes núcleos argumentais: cotidiano do trabalho, riscos ocupacionais e relação com os serviços de saúde. A reciclagem para muitos trabalhadores é uma última opção de sobrevivência dentro das regras sociais do mundo do trabalho; e a possibilidade de trabalhar, apesar de todas as suas dificuldades, esforços e sobrecargas, é vista como uma forma digna de sobrevivência e valorizada como um dos maiores bens de suas vidas.

Recycling collectors are excluded for the activity they perform (in inadequate conditions and with no social recognition). The objective of this research was to understand the health-disease-care process of people who work with recycling to help build strategies to welcome this population in Primary healthcare. It was an exploratory, descriptive, and qualitative study where eight interviews were conducted with recycling workers. The analysis was conducted based on Gadamer’s hermeneutics. The analysis evidenced three large argumentative nuclei: work routine, occupational risks, and health service relation. For most workers, recycling is their last resort to survive in the social rules of the occupational world, despite all its difficulties, efforts, and burdens. It is considered a dignified way of survival and valued as one of the greatest assets in their lives: the possibility to work.

ABSTRACT The effects of a diet supplemented with 5% marine fish oil, 5% refined palm oil, 5% soybean oil, and a combination of the three on reproductive parameters of females Rhamdia quelen was investigated. Spawning was artificially induced to evaluate rates of fertilization, hatching and larvae normality. Fatty acid profiles of the diets, ovaries and oocytes were determined. A higher spawning rate (%) was observed for diets containing fish oil (78.65 ± 3.60) and palm oil (77.15 ± 3.97), followed by oil mix (65.46 ± 4.57). The diet containing soybean oil was associated with significantly lower fertilization (60.14 ± 5.66; P < 0.05) than the palm and fish oil diets. Lower fertilization may be explained by a high level of n-6 fatty acids in the diet, which possibly accelerate the oocyte maturation. Satisfactory fecundity (P > 0.05) were observed for all tested diets, whit 289.77 ± 23.90 (palm oil) until 323.31 ± 38.45 oocytes g-1 body weight (fish oil). The treatments were not shown to influence oocyte size, larval size or rate of larva deformity. Oocyte fatty acid composition was like that of gonads. Docosahexaenoic (DHA; C22:6 n-3) fatty acid was preferentially deposited in ovaries and oocytes. Ratios of n3/n6, DHA/EPA, EPA/ARA, did not affect the reproductive performance of females. Therefore, regarding female reproductive performance, the vegetable lipid sources tested are suitable for being used in R. quelen diet, and palm oil, in particular, is considered an excellent alternative to fish oil.
