Resumen Introducción: Datos de varios países del mundo sugieren que los niños con COVID-19 podrían presentar síntomas diferentes y menos graves que los adultos. Sin embargo, los patrones epidemiológicos y clínicos en este grupo poblacional son poco claros. Métodos: El presente es un estudio observacional, con una caracterización inicial transversal-analítica, y con un componente longitudinal o de seguimiento a un grupo de menores con sospecha y/o diagnóstico confirmado de COVID-19, que presentaron desenlaces como mejoría, traslado a un nivel superior de atención o defunción por sintomatología respiratoria. Los niños recibieron atención médica en el Hospital General Regional con Medicina Familiar N.° 1 (HGR C/MF N.° 1), y se les realizó prueba de reacción en cadena de la polimerasa en tiempo real (RT-PCR). Resultados: Se estudiaron 98 niños como casos sospechosos para COVID-19, a quienes se les realizó RT-PCR. Del total, 24 resultaron positivos y 74 fueron negativos. La mediana de edad de los participantes fue 64,4 meses (0 a 203 meses), 55 menores eran de sexo masculino, 59 niños tuvieron manejo ambulatorio, y de estos, 14 presentaron resultado positivo. Entre los que requirieron manejo hospitalario (39), 10 niños dieron positivo para SARS-CoV-2, 84,7% alcanzaron mejoría y fueron dados de alta, 4 fueron trasladados a hospitales de nivel superior de atención. De los 98 niños en estudio, 11 fallecieron, 7 con resultado negativo y 4 con resultado positivo para SARS-CoV-2. Conclusiones: Los principales síntomas de la población pediátrica en este estudio fueron fiebre, tos y malestar general. De los niños que fallecieron, 4 presentaron resultado positivo para SARS-CoV-2, no obstante, estos presentaban otras comorbilidades.

Abstract Introduction: Data from several countries around the world suggest that children with COVID-19 may present different and less severe symptoms than adults. However, the epidemiological and clinical patterns in this population group have been unclear. Methods: This is an observational study, with an initial cross-analytical characterization, and with a longitudinal or follow-up component in a group of minors with suspected and or confirmed case of COVID-19, which have outcomes such as improvement, transfer to a higher level of care or death due to respiratory symptoms. The children received medical attention at the Regional General Hospital with Family Medicine No 1 (HGR C / MF No 1), and underwent a Real Time Polymerase Chain Reaction test (RT-PCR). Results: 98 children were studied as suspected cases for COVID-19, who underwent RT-PCR. Of the total 24 were positive and 74 were negatives. The median age was 64.4 months (0 to 203 months), 55 minors were male, 59 children had outpatient management, and of these, 14 had a positive result. Among those who required hospital management (39), 10 children were positive for SARS-CoV-2, 84.7% achieved improvement and were discharged, and four were transferred to a higher level of care hospital. Of the 98 children in the study, 11 died, seven had a negative result and four a positive result for SARS-CoV-2. Conclusions: The main symptoms of the pediatric population in this study were fever, cough and general discomfort. Four of those who died had a positive result for SARS-CoV-2, however, they had other comorbidities.

Resumen Marco contextual: el nacimiento de un hijo conlleva cambios en la vida de la pareja que incluyen la sexualidad y pocas veces se explora la perspectiva masculina. Objetivos: describir la satisfacción sexual de los hombres después del nacimiento de un hijo; verificar la existencia de una relación entre la satisfacción sexual y las características personales y familiares. Metodología: estudio descriptivo-correlacional, transversal en padres de niños de idade >= 1 mes e <= 1 año. El muestreo fue no probabilístico (n = 101), cuyo cuestionario se distribuyó en línea integró la Nueva Escala de Satisfacción Sexual validado para población portuguesa por Pechorro et al. (2015). Resultados: la satisfacción sexual de los hombres fue positiva, sin embargo, la puntuación más baja se atribuyó a los ítems relacionados con la disponibilidad, creatividad y diversidad de su pareja para las relaciones sexuales. No hubo una relación estadísticamente significativa entre la satisfacción sexual de los hombres y sus características personales y familiares. Conclusión: el hombre tiene expectativas en relación a su pareja con respecto a la sexualidad. Los profesionales de la salud deben valorar la sexualidad desde la perspectiva del casal, en la transición a la paternidad. Se sugiere inversión en comunicación y reparto equitativo de tareas domésticas entre la pareja, de modo que la disponibilidad se reserve para la sexualidad.

Abstract Background: the birth of a child brings changes to the couple's life which includes their sexuality, in which the man´s perspective is rarely explored. Objectives: to describe men's sexual satisfaction after the birth of a child; verify the existence of a relationship between sexual satisfaction and personal and family characteristics. Methodology: descriptive-correlational, cross-sectional study with fathers of children aged >= 1 month e <= 1 year. The sampling was non-probabilistic (n=101), whose questionnaire was distributed online and integrated the New Sexual Satisfaction Scale validated for the Portuguese population by Pechorro et al. (2015). Results: the men's sexual satisfaction was positive, however, the lowest score was attributed to items related to their partner's availability, creativity and diversity for sexual intercourse. There was no statistically significant relationship between men's sexual satisfaction and their personal and family characteristics. Conclusion: the man has expectations in relation to his partner with regard to sexuality. Health professionals should value sexuality from the couple´s perspective, in the transition to parenthood. Investment in communication and equal sharing of domestic tasks between the couple is suggested, so that availability is reserved for sexuality.

Enquadramento: O médico de família (MF) lida frequentemente com utentes com manifestações dermatológicas, cujo diagnóstico é um desafio. O eczema numular é um tipo disseminado de eczema que se caracteriza por lesões discoides pruriginosas e bem delimitadas. Atinge mais frequentemente indivíduos do sexo masculino com idade superior a 50 anos. O seu diagnóstico é clínico. Com este caso pretende-se sensibilizar o MF para a sua apresentação clínica, diagnósticos diferenciais, tratamento e prognóstico. Descrição do caso: Homem de 53 anos, serralheiro, casado, com antecedentes pessoais de tabagismo, alcoolismo, dislipidemia e hipoacusia de transmissão, que recorre à consulta por aparecimento de máculas e placas eritemato-descamativas, arredondadas, de diâmetro variável (1-3cm), muito pruriginosas, dispersas nos membros superiores e inferiores, com cerca de três meses de evolução. Referia agravamento noturno do prurido. Sem atingimento do estado geral ou outros sintomas sistémicos. Desconhecia processo infecioso no início das manifestações cutâneas. Previamente ao diagnóstico, o utente foi observado em três consultas efetuadas por médicos diferentes: inicialmente, as lesões foram interpretadas como reação alérgica, uma vez que manuseava produtos irritantes no local de trabalho; posteriormente foi tratado para Tinea corporis e, por último, foi colocada a hipótese de se tratar de uma Psoríase gutata e foi medicado em consonância, sem melhoria. Dada a dificuldade diagnóstica foi pedido parecer à dermatologia, via Alert, que considerou tratar-se de um eczema numular. Comentário: O eczema numular é uma entidade com etiopatogenia desconhecida, cujas manifestações clínicas são características, atingindo preferencialmente as extremidades. É importante considerar outros diagnósticos diferenciais, como dermatite atópica, dermatite alérgica, Tinea corporis e Psoríase gutata. O tratamento incluiu aplicação de hidratantes e corticoides tópicos. O seu prognóstico é excelente, apesar de existir possibilidade de recorrência. A divulgação deste caso clínico permitirá refletir acerca desta patologia, reforçando a importância do diagnóstico diferencial e do tratamento adequado.

Introduction: The family doctor frequently handles patients with dermatological diseases, whose diagnostic is a challenge. Nummular eczema is widespread eczema that is characterized by pruritic and well delimited discoid lesions. It affects more commonly males over 50 years of age and the diagnostic is clinical. This case aims to remind family doctors its clinical presentation, differential diagnosis, treatment, and prognosis. Case report: Man, 53 years old, locksmith, married, with previous history of smoking, alcoholism, dyslipidemia and transmission hypoacusia, who refers the onset of macules and erythematous-desquamative plaques, rounded, of variable diameter (1-3cm), very pruritic, scattered in the upper and lower limb, with three month's evolution. He reported nocturnal worsening of pruritus. Not achieving general health or other systemic symptoms. There was no infectious process at the onset of the cutaneous manifestations. Prior to the diagnosis, the patient was observed in three consultations performed by different physicians: initially, the lesions were interpreted as an allergic reaction, as he handled irritating products at work, later as Tinea corporis and finally, it was hypothesized that it was a Psoriase Gutata and was treated accordingly without success. Given the diagnostic difficulty, a second opinion was requested to dermatology, who considered it to be nummular eczema. Comment: Nummular eczema is an entity with unknown etiopathogenesis, whose clinical manifestations are particular, preferably reaching the extremities. It is important to consider other differential diagnoses, such as atopic dermatitis, allergic dermatitis, corpora, and Psoriase gutata. The treatment included the application of moisturizers and topical corticosteroids. Its prognosis is excellent, despite the possibility of recurrence. The disclosure of this clinical case will allow us to reflect on this pathology, reinforcing the importance of differential diagnosis and appropriate treatment.

ABSTRACT High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat conditioning were evaluated. The objective of this study was to evaluate the possible interactions and effects of dietary electrolyte balance and early heat conditioning on feed intake, body weight, feed conversion ratio, mortality, energy bioeconomic index, fecal moisture, abdominal fat, and breast meat color (L*a*b*) of broilers submitted to chronic or acute heat stress. In total, 1280 chicks, were equally divided in experiment I (chronic heat stress, 6h/day at 32ºC from 35 to 39 d of age) and II (acute heat stress, 36 ºC for 6h at 38 days of age). The data of both experiments were combined and analyzed according to a 2x2x2 factorial arrangement (early heat conditioning (ETC) or not; fixed dietary electrolyte balance (EB) or not; and exposure to acute or chronic heat stress). ETC consisted of exposing 5-d-old birds to 36.0 °C for 24 hours. No interaction among the evaluated factors was detected. Birds exposed to acute heat stress presented significantly higher compared with chronic heat stress. Fixed dietary EB resulted in significantly higher fecal moisture. Lower abdominal fat percentage was obtained in birds exposed to chronic relative to acute heat stress. Higher breast meat L* and b* values were observed in birds exposed to acute heat stress than those submitted to chronic heat stress, indicating worse meat quality.

RESUMO Introdução O objetivo do estudo foi conhecer a opinião dos pediatras sobre o estágio de Cuidados de Saúde Primários (CSP) e suas expectativas relativamente aos Cuidados de Saúde Primários Pediátricos em Portugal. Métodos Questionário online dirigido a residentes de Pediatria e pediatras de 22 hospitais portugueses de 1 de julho a 31 de agosto de 2010. Foram analisados dados demográficos e profissionais, e suas expectativas relativamente aos CSP. Resultados Foram enviados 270 e-mails (taxa de resposta de 57%). Quinze (37,5%) supervisionados por pediatras consideraram que a duração ideal do estágio seria de três a seis meses, enquanto 45 (60,8%) supervisionados por médicos de família (MF) consideraram de zero a três meses (p < 0,0001). Os inquiridos supervisionados por pediatras ficaram globalmente satisfeitos/muito satisfeitos em 37 (92,5%) casos versus 51 (68,9%) coordenados por MF (p = 0,005). Setenta e dois (52,2%) consideraram que a vigilância pediátrica nos CSP deve ser assegurada por MF e pediatras consultores. Oitenta e oito (63,8%) inquiridos gostariam de assumir a função de pediatra consultor nos CSP. Conclusões O estágio de CSP é importante na formação dos pediatras, e alguns aspetos devem ser melhorados. É necessário investir na saúde pública integrada nos CSP.

ABSTRACT Introduction The aim of our study was to identify opinions on training in Primary Care and expectations on the future of Pediatric Primary Care. Methods An online questionnaire was sent to Pediatric trainees and young Pediatricians at 22 Portuguese hospitals over the period of July 1 to August 31, 2010. Results Two-hundred and seventy e-mails were sent, with a response rate of 57%. Fifteen (37.5%) of those supervised by Pediatricians considered the optimal training period to be 3-6 months, while 45 (60.8%) supervised by Family Physicians considered the period to be 0-3 months (p < 0.0001). Respondents supervised by Pediatricians were largely satisfied/very satisfied with a percentage of 92.5%, versus 68.9% supervised by Family Physicians (p = 0.005). Seventy two (52.2%) stated that Pediatric surveillance in Primary Care should be performed both by Family Physicians and Pediatric consultants. Eighty eight (63.8%) respondents would like to assume the future role of Pediatrician in Primary Care. Conclusions Training in primary care is important to pediatricians’ training and some aspects should be improved. Investments must be made into public health integrated with primary care.

Nos programas de melhoramento é importante reduzir o tempo consumido realizando-se repetições de avaliações além do necessário. Entretanto, esta redução não deve comprometer a representatividade e confiabilidade das informações. Assim, um importante fator de sucesso em programas de melhoramento é o conhecimento do número ideal de repetições para avaliação de características de importância comercial em cada espécie ou população. Nesse contexto, este trabalho teve como objetivo determinar o coeficiente de repetibilidade de oito características biométricas em quatro populações de pimenteiras ornamentais, buscando aumentar a eficiência do processo de avaliação e seleção. Não houve influência significativa do método de cálculo utilizado sobre a estimativa do coeficiente de repetibilidade. Os resultados indicaram que cinco plantas são suficientes para avaliar altura de planta; número, comprimento e largura de folha; e número, comprimento e largura de frutos de genótipos de pimenteira ornamental, com coeficiente de determinação de 90%.

Breeding programs seek to reduce the time spent assessing characteristics more times than necessary. However, this reduction should in no way undermine the representativeness and reliability of the information. Thus, an important success factor in breeding programs is the knowledge of the ideal number of assessments needed to evaluate commercially important characteristics in each species or population. In this context, this study aimed to determine the repeatability coefficient of eight biometric traits in four populations of ornamental pepper, seeking to increase the efficiency of evaluation and selection processes. There was no significant influence of the calculation method used over the estimate of the repeatability coefficient. The results indicated that five plants are necessary to assess plant height; leaf number, length and width; and fruit number, length and width in the ornamental pepper material we used with a determination coefficient of 90%.

ABSTRACTThe objective of this study was to compare the effects of two methods (electrical water bath or carbonic gas atmosphere) for stunning or killing broiler chickens prior to bleeding on weight loss due to bleeding and meat traits. A completely randomized design with 2 x 2 factorial arrangement (electrical or gas system x stunning or killing) was applied. The time required for stunning and killing and the birds' behavior were evaluated for the gas exposure method. The birds killed by the electrical method retained more blood than those killed by the exposure to gas and, therefore, presented redder meat. The exposure to 10 to 15% CO2 atmosphere caused discomfort reactions in 100% of birds, and the intensity of reaction presented a wide variation: 35% for weak reaction, 40% for intermediate reaction, and 25% for strong reaction. The time required to stun or kill the birds by CO2 exposure varied from 28 to 97 seconds and from 42 to 158 seconds, respectively. It was concluded that the time required to stun or to kill the birds by CO2 exposure widely varied and caused discomfort reactions; however, meat traits were not influenced by the methods used in this experiment.

Abstract: En | Text: En | PDF: En

Nutritionists need to make commercial decisions about the optimal nutrient content broiler feeds. In order to demonstrate that broiler prices may influence dietary nutrient density, this study developed quadratic feed intake and weight gain equations, according to broiler sex and feeding phase, to be applied in a nonlinear feed formulation model. Four hundred and eighty Cobb broilers were allotted to a completely randomized experimental with six treatments, each with four replicates of 10 birds each, from 1 to 56 days old. Treatments consisted of diets containing 2800, 2900, 3000, 3100, 3200, or 3300 kcal metabolizable energy (ME)/kg and constant nutrient to ME ratio. A nonlinear version of the PPFR feed formulation software (http://www.fmva.unesp.br/ppfr) was developed with the objective of optimizing energy density and bird performance. According to the results, when the models are applied in the PPFR nonlinear spreadsheet, the most favorable nutrient density content is defined by mathematical models, as optimized by the Excel Solver tool by means of cost/benefit comparisons and as a function of rearing phase (starter, grower, and finisher) and sex. This contradicts the recommendations of genetic company manuals and published requirement tables, whose goal is to maximize weight gain and do not necessarily guarantee maximum economic efficiency.

Abstract: En | Text: En | PDF: En

Several physiological and metabolic changes are triggered in broilers submitted to high environmental temperatures, resulting in performance losses. Feed formulation manipulation of the dietary electrolyte balance may be applied to reduce the negative impact of heat stress on broiler performance. This experiment was carried out to evaluate the effect of the manipulations of dietary electrolytes by combining changes in the electrolyte (Na++K+-Cl-) balance (EB) and in the [(K++Cl-)/Na+] ratio (ER) in broiler feeds. In total, 1575 male broilers between 21 and 46 days old were allotted to 15 treatments in a 5x3 factorial arrangement, consisting of five diets with different EB/ER combinations (150/3, 250/2, 250/3, 250/4, and 350/3). Birds were submitted to heat stress at 25 or 35 days old. Live performance, mortality rate, and carcass traits were evaluated. The strategic formulation of diets with different EB and ER improves live performance and minimize the effect of heat stress on broilers. Under thermoneutral conditions, an EB of 250 mEq/kg and an ER of 3 are recommended, whereas under heat stress, and EB of 350 mEq/kg and an ER of 3 should be applied.

The objective of this study was to evaluate the effect of different supplementation levels of Rhodocyclus gelatinosus biomass on the performance and pigmentation of broilers. Cobb broilers were raised in pens and were fed a sorghum-based diet until 35 days of age. At the 36th day of age, ninety-six birds were randomly distributed to four treatments consisting of experimental diets with different supplementation levels of Rhodocyclus gelatinosus biomass (0, 75, 150 and 300 ppm) added to the finisher basal diet, which were given for seven days. A completely randomized experimental design was used, with four treatments, four replicates and six broilers per parcel. Birds and diets were weighed at the 36th and at the 42nd day of age for performance analysis. There was no significant effect on broiler feed intake. Significant differences in weight gain and feed conversion were seen between the control group and the groups supplemented with 75 and 150 ppm. The treatment with the highest supplementation level and the control group had best weight gain and feed conversion. Color analysis showed that R. gelatinosus biomass supplementation resulted in more yellow breast skin and increased darkening and color purity in breast and thigh meat of broilers, but had no effect on lightness or color purity of breast and thigh skins.

Dados a respeito de 116.699 partos (1062 gemelares e 115.637 únicos) ocorridos entre 1984 e 1996 na maior maternidade de Campinas, SP, Brasil, permitiram fazer as seguintes observações: 1) a despeito da baixa porcentagem de nascimentos gemelares (0,9%), os gêmeos foram responsáveis por 10,7% dos óbitos neonatais precoces e 3,5% dos natimortos. Em relação aos recém-nascidos de parto único, a probabilidade de natimortalidade e mortalidade neonatal precoce dos gêmeos foi, respectivamente, 1,9 e 6,5 vezes menor. 2) A proporção de gêmeos entre os óbitos neonatais precoces vem decrescendo, podendo essa tendência ser atribuída à melhoria da assistência pré- e perinatal. 3) Os três primeiros dias após o nascimento constituíram o período crítico de ocorrência dos óbitos neonatais tanto dos gêmeos quanto dos recém-nascidos de parto único. 4) A mortalidade perinatal incidiu mais freqüentemente nos pares MM, que foram seguidos pelos pares FF, e foi menor nos pares MF. 5) A taxa anual de óbitos neonatais precoces tem decrescido nos recém-nascidos de parto único e nos gêmeos, o mesmo ocorrendo com a taxa anual de natimortos de parto único, mas o decréscimo foi mais acentuado nos recém-nascidos do sexo feminino. 6) Durante o período analisado a razão de sexo esteve praticamente estável nos recém-nascidos de parto único vivos, mostrou variação cíclica nos recém-nascidos que foram a óbito na primeira semana e revelou tendência crescente nos natimortos. A razão de sexo dos gêmeos que foram a óbito na primeira semana e daqueles que sobreviveram também mostrou crescimento acentuado no período entre 1984 e 1996. 7) Nos recém-nascidos de parto único a idade gestacional média foi maior naqueles que sobreviveram, os quais foram seguidos pelos natimortos, sendo menor nos que foram a óbito na primeira semana. Nos gêmeos a idade gestacional média dos sobreviventes foi maior do que a dos falecidos na primeira semana, mas não diferiu daquela apresentada pelos natimortos. 8) O peso médio de todos os recém-nascidos foi maior entre os sobreviventes, que foram seguidos pelos natimortos, e menor naqueles que foram a óbito na primeira semana. 9) Os índices de Apgar > ou = 7 obtidos cinco minutos após o nascimento não podem ser considerados como um indicador de boas condições clínicas do recém-nascido, porque quase a metade dos óbitos neonatais precoces mostraram índices de Apgar de cinco minutos variando de 7 a 10.

Analysis of 116,699 deliveries (1062 twin pairs and 115,637 singletons) which occurred from 1984 to 1996 at the largest obstetric center in Campinas, SP, Brazil, provided the following conclusions: 1) despite the low percentage of twin births (0.9%), 10.7% of all early neonatal deaths and 3.5% of all stillbirths were twins. Compared to singletons, the likelihood of stillbirths and early neonatal deaths among twins was 1.9 and 6.5 times greater, respectively. 2) The proportion of twins among early neonatal deaths tended to decrease, probably because of improvements in prenatal and perinatal care. 3) The critical period for early neonatal deaths in singletons and twins lasted for the three first days after birth. 4) The incidence of perinatal deaths among twins was highest among MM pairs, followed by FF pairs, and lowest among MF pairs. 5) There was a trend towards a decrease in the annual rate of early neonatal deaths among both singletons and twins, and of stillbirths among singletons, the latter being more conspicuous among females. 6) The sex ratio of singletons was practically stable among living newborns, but showed strong cyclic variation among early neonatal deaths, and a tendency to increase among stillbirths. Twins who died in the first week, as well as living twins showed a strong increase in their sex ratio from 1984 to 1996. 7) The mean gestational age of singletons was highest among living newborns followed by stillbirths, and was lowest among early neonatal deaths. The mean gestational age of living twins was higher than that of early neonatal deaths, but not different from that of stillbirths. 8) The mean birth weight of singletons and twins was highest among living newborns, followed by stillbirths, and lowest among early neonatal deaths. 9) Apgar scores > or = 7 obtained five minutes after birth are inadequate as a reliable indicator of the clinical condition of the newborn, since almost half of the early neonatal deaths had 5-min Apgar scores varying from 7 to 10.
