RESUMO

Cerca de um terço dos pacientes com COVID-19 em unidades de terapia intensiva (UTI) apresentam injúria renal aguda (IRA) dialítica. Poucos estudos têm avaliado a sobrevida de pacientes com IRA em UTI exclusivamente pública. O objetivo do estudo foi avaliar a sobrevida intra-hospitalar em 90 dias de pacientes com e sem IRA dialítica internados com COVID-19 grave. Trata-se de uma coorte histórica de um hospital geral em Joinville, Santa Catarina/Brasil. Foram incluídos todos os pacientes admitidos na UTI entre março e dezembro de 2020 com diagnóstico confirmado de COVID-19. Definiu-se IRA como a presença de alteração de função renal aguda com necessidade de hemodiálise. Utilizou-se modelo multivariado por regressão de Cox para avaliar a sobrevida de pacientes com e sem IRA dialítica. Os resultados do estudo demonstraram que dos 187 pacientes incluídos (55,5% homens) com média de idade de 62,8±13,6 anos, 37,4% apresentaram IRA dialítica. Pacientes com IRA dialítica usaram mais drogas vasoativas, tinham maior gravidade na admissão e maior mortalidade (84,3% vs. 63,2%; p=0,002) em relação àqueles sem IRA. O risco de morte nos pacientes com IRA foi maior (RR bruto= 1,60; IC 95% 1,13-2,26; p= 0,007). Após ajustes para idade, sexo, comorbidades e gravidade clínica, a presença de IRA dialítica se manteve associada a uma frequência maior de mortalidade em 90 dias (RR= 1,49; IC 95% 1,03-2.15; p=0,032). A sobrevida de pacientes com COVID-19 grave e IRA dialítica na amostra estudada foi menor em relação a UTIs privadas no Brasil, o que sugere desigualdades no sistema público.

About one third of patients with COVID-19 in intensive care units (ICU) have acute kidney injury (AKI) requiring dialysis. Few studies have evaluated the survival ratel of patients with AKI in exclusively public ICUs. The aim of this study was to evaluate the 90-day in-hospital survival of patients with and without AKI requiring dialysis hospitalized with severe COVID-19. This is a historical cohort of a general hospital in Joinville, Santa Catarina/Brazil. All patients admitted to the ICU between March and December of 2020 with a confirmed diagnosis of COVID-19 were included. AKI was defined by the presence of acute renal function alteration requiring hemodialysis. A multivariate Cox regression model was used to assess the survival of patients with and without AKI requiring dialysis. The results of the study showed that, of the 187 patients included (55.5% men) with a mean age of 62.8±13.6 years, 37.4% had AKI requiring dialysis. Patients with AKI requiring dialysis used more vasoactive drugs, had greater severity on admission and higher mortality rate (84.3% vs. 63.2%; p=0.002) compared to those without AKI. The risk of death in patients with AKI was higher (crude RR= 1.60; 95% CI 1.13-2.26; p= 0.007). After adjustments for age, sex, comorbidities and clinical severity, the presence of AKI requiring dialysis remained associated with a higher frequency of 90-day mortality (RR= 1.49; 95% CI 1.03-2.15; p=0.032). The survival of patients with severe COVID-19 and AKI requiring dialysis in the studied sample was lower compared to private ICUs in Brazil, which suggests inequalities in the public system.

RESUMO

O tomate é a hortaliça mais produzida e consumida, tendo aceitabilidade tanto para o consumo in natura quanto para a industrialização. Apesar da ampla aceitação dos tomates, o consumidor apresenta como exigência para aquisição do fruto a qualidade,mensurada através de parâmetros como sólidos solúveis (SS) e acidez titulável (AT). Uma técnica de análise química, não destrutiva e não invasiva e de resposta rápida, é a de espectroscopia de absorção na região do infravermelho próximo que tem sido bastante utilizada em várias indústrias, desde agrícola a petroquímica.Considerando a produção em alta escala, a qualidade do tomate exigida pelos consumidores e por se tratar de uma técnica não destrutiva e não invasiva da espectroscopia no infravermelho próximo (Near Infrared Spectroscopy ­NIR),faz-se necessário modelos testados em condições comerciais garantindo um modelo de infravermelho próximo para tomate facilitando a classificação. Realizou-sea validação de forma externa e prática dos modelos de infravermelho próximo para tomate in natura, comparando com os métodosdestrutivos e conferindo a acurácia dos modelos na qualificação do fruto quanto aos teores de sólidos solúveis e acidez. O presente trabalho apresenta modelos do projeto executado de 2018 a 2019, construídos atravésdos aplicativos Model Builder e The Unscrambler e selecionados a partir de parâmetros como coeficiente de calibração, coeficiente da validação cruzada, erro médio do conjunto de calibração, e da validação cruzada e cálculo do desvio do resíduo de calibração. Os resultados foram obtidos através da previsão do modelo para os atributos sólidos solúveis (SS) e acidez titulável (AT), do tomate de mesa com maior variabilidade de produção. O modelo para SS apresenta potencialidade para uso comercial, seja na determinação de ponto de colheita, seja na quantificação de qualidade do vegetal. Já para AT, o NIR portátil não produziu um modelo aplicável pela limitação do comprimento de onda.(AU)

Tomatoes are the most commonly used and consumed vegetables, being acceptable for fresh consumption as well as for industrialization. Despite the wide acceptance of tomatoes, the consumer presents quality as a requirement for the acquisition of the fruit, which is measured through parameters such as soluble solids (SS) and titratable acidity (TA). A chemical analysis technique, non-destructive and non-invasive and with fast response, is an absorption spectroscopy in the near infrared region that has been widely used in several industries, from agricultural to petrochemicals. Demanding large-scale production, the quality of tomatoes demanded by consumers and as it is a non-destructive and non-invasive technique of near infrared spectroscopy (NIR), it is still necessary to test models under commercial conditions, ensuring a near infrared model for tomatoes making sorting easy. An external and practical validation of the near infrared models for fresh tomatoes was carried out, comparing them with the destructive methods and checking the accuracyof the models in qualifying the fruit in terms of soluble solids and acidity. This paper presents project models obtained from 2018 to 2019, built from the Model Builder and The Unscrambler programs and selected from parameters such as calibration coefficient, cross validation coefficient, average error of the calibration set, and cross validation and calculation of the residual calibration deviation. The results obtained through the prediction of the model for the soluble solid attributes and titratable acidity, of the table tomato with greater production variability. The model for SS of table tomato has potential for commercial use, either in determining the harvest point, or quantifying the vegetable's quality. For AT or portable NIR, it did not produce an applicable model due to the wave length limitation(AU)

RESUMO

The reproductive strategy of the non-native predator cichlid Cichla kelberi was determined to explain its success after more than 60 years of being introduced into an isolated reservoir in southeastern Brazil. This was one of the first-known translocations of the genus Cichla out of its natural range. Macro- and microscopy characteristics of the gonadal development stages and the maturation phases, along with the reproductive features (size at first maturation size, gonado-somatic index and sex ratio), were described. It was hypothesized that the stable conditions of the reservoir, with low connectivity, weakly defined spatial gradient and slight seasonal changes in environmental variables, favour the equilibrium strategy that enables predators to have high offspring survivorship because of great parental investment in individual progeny. Sex ratio was well balanced, with males and females reaching first maturity between 30.0 and 28.6 cm total length (LT ), respectively. The stages of oocyte (primary and secondary growth, vitellogenic and atresia) and spermatocyte (spermatogonia, spermatocytes, spermatids and spermatozoa) development were identified. Five phases of gonadal development (immature, developing, spawning capable, regressing and regenerating) were described for both sexes. A long reproductive season was found, with spawning peaks in August/September and, to a lesser extent, in April/May. Parental care and spawns in parcels (batch spawns) corroborated the raised equilibrium strategy that was effective in this isolated reservoir. This species developed reproductive mechanisms that fit to different environmental conditions, with multiple spawning being associated with lentic environments and asynchronous development of oocytes, which are released over long periods. The reproductive plasticity in reservoirs may be one of the main factors inherent to the successful of colonization and establishment of the peacock bass in the environments in which they were introduced.

RESUMO

BACKGROUND: In most emergency situations or severe illness, patients are unable to consent for clinical trial enrollment. In such circumstances, the decision about whether to participate in a scientific study or not is made by a legally designated representative. OBJECTIVE: To address the willingness of patients admitted to the intensive care unit (ICU) to be enrolled in a scientific study as volunteers, and to assess the agreement between patients' and their legal representatives' opinion concerning enrollment in a scientific study. METHODS: This survey was conducted in two hospitals in São Paulo, Brazil. Patients (≥18 years) with preserved cognitive functions accompanied by a surrogate admitted to the ICU were eligible for this study. A survey containing 28 questions for patients and 8 questions for surrogates was applied within the first 48h from ICU admission. The survey for patients comprised three sections: demographic characteristics, opinion about participation in clinical research and knowledge about the importance of research. The survey for legal representatives contained two sections: demographic characteristics and assessment of legal representatives' opinion in authorizing patients to be enrolled in research. RESULTS: Between January 2017 and May 2018, 208 pairs of ICU patients and their respective legal representatives answered the survey. Out of 208 ICU patients answering the survey, 73.6% (153/208) were willing to be enrolled in the study as volunteers. Of those patients, 65.1% (97/149) would continue participating in a research even if their legal representative did not support their enrollment. Agreement between patients' and surrogates' opinion concerning participation was poor [Kappa = 0.11 (IC95% -0.02 to 0.25)]. If a consent for study participation had been obtained, 69.1% (103/149) of patients would continue participating in the study until its conclusion, and 23.5% (35/149) would allow researchers to use data collected to date, but would withdraw from the study on that occasion. CONCLUSION: The majority of patients admitted to the ICU were willing to be enrolled in a scientific study as volunteers, also after a deferred informed consent procedure has been used. Nevertheless, contradictory opinions between patients and their and their legal representatives' concerning enrollment in a scientific study were often observed.

RESUMO

Classifying species into groups based on taxonomic relationship and functions are objective approaches to evaluate environmental and anthropogenic influences on coastal fishes. We evaluated temporal (1993-1995 and 2012-2015) changes in the taxonomic and functional indices in three zones of a tropical bay heavily impacted over the recent decades. We tested the hypothesis that both indices decrease over time as result of the environmental degradation. A decrease in the taxonomic richness and abundance was observed mainly of the inner zone. The functional structure remained relatively stable, but the functional originality decreased significantly between the two periods. This functional loss is of particular concern because the loss of species with unique treats may generate a series of ecosystem damage. This information tells us that the use of functional indices is essential to complement taxonomic assessments and to detect a more detailed understanding of the real dimension of biodiversity loss in impacted environments.

RESUMO

OBJECTIVE: to evaluate the application of a deterministic routine for identifying multiple pregnancies on the Brazilian Live Birth Information System (SINASC). METHODS: SINASC data deduplication and linkage with the mortality database (fetal deaths) for Rio de Janeiro state for the period 2007-2008; we used a deterministic routine, using a key based on SINASC maternal and birth information, complemented by manual review. RESULTS: of the 433,874 SINASC records, 9,036 (2.1%) were classified as multiple pregnancy newborns; after implementing the routine, we reclassified 385 records as twins, and 286 as singletons; accuracy of multiple pregnancy information on the SINASC database was high (sensitivity=95.8%; specificity=99.9%); applying the routine without the manual review process increased sensitivity by 4.2%, with no significant change of specificity. CONCLUSION: despite the accuracy of information regarding multiple pregnancy held on SINASC, we suggest the use of this routine as an option for improving classification of twins.

RESUMO

RESUMO Objetivo: Caracterizar os pacientes com doença crítica crônica e identificar os preditores relacionados à evolução para doença crítica crônica. Métodos: Coleta prospectiva de dados por 1 ano realizada na unidade de terapia intensiva de um hospital geral localizado na Região Sul do país. Construíram-se três modelos de regressão logística para identificar os fatores associados com doença crítica crônica. Resultados: Dentre os 574 pacientes admitidos à unidade de terapia intensiva durante o período do estudo, 200 foram submetidos à ventilação mecânica. Destes, 85 (43,5%) pacientes desenvolveram doença crítica crônica, totalizando 14,8% de todos os pacientes admitidos à unidade de terapia intensiva. O modelo de regressão que avaliou os fatores prévios à admissão à unidade de terapia intensiva associados com doença crítica crônica identificou insuficiência renal crônica submetida à diálise (OR 3,57; p = 0,04) e diagnóstico neurológico quando da admissão ao hospital (OR 2,25; p = 0,008) como fatores independentes. No modelo que avaliou a associação de doença crítica crônica com situações ocorridas durante a permanência na unidade de terapia intensiva, destacaram-se fraqueza muscular (OR 2,86; p = 0,01) e úlceras por pressão (OR 9,54; p < 0,001). Na análise multivariada global (fatores prévios e situações ocorridas durante a permanência na unidade de terapia intensiva), destacaram-se admissão ao hospital por doenças neurológicas (OR 2,61; p = 0,03) e desenvolvimento de úlceras por pressão (OR 9,08; p < 0,001). Conclusão: A incidência de doença crítica crônica foi similar à observada em outros estudos e teve associação mais forte com o diagnóstico de doenças neurológicas quando da admissão ao hospital e insuficiência renal crônica submetida à hemodiálise, assim como com complicações desenvolvidas durante a hospitalização, como úlceras por pressão e fraqueza muscular.

ABSTRACT Objective: To characterize patients with chronic critical illness and identify predictors of development of chronic critical illness. Methods: Prospective data was collected for 1 year in the intensive care unit of a general hospital in Southern Brazil. Three logistic regression models were constructed to identify factors associated with chronic critical illness. Results: Among the 574 subjects admitted to the intensive care unit, 200 were submitted to mechanical ventilation. Of these patients, 85 (43.5%) developed chronic critical illness, composing 14.8% of all the patients admitted to the intensive care unit. The regression model that evaluated the association of chronic critical illness with conditions present prior to intensive care unit admission identified chronic renal failure in patients undergoing hemodialysis (OR 3.57; p = 0.04) and a neurological diagnosis at hospital admission (OR 2.25; p = 0.008) as independent factors. In the model that evaluated the association of chronic critical illness with situations that occurred during intensive care unit stay, muscle weakness (OR 2.86; p = 0.01) and pressure ulcers (OR 9.54; p < 0.001) had the strongest associations. In the global multivariate analysis (that assessed previous factors and situations that occurred in the intensive care unit), hospital admission due to neurological diseases (OR 2.61; p = 0.03) and the development of pressure ulcers (OR 9.08; p < 0.001) had the strongest associations. Conclusion: The incidence of chronic critical illness in this study was similar to that observed in other studies and had a strong association with the diagnosis of neurological diseases at hospital admission and chronic renal failure in patients undergoing hemodialysis, as well as complications developed during hospitalization, such as pressure ulcers and muscle weakness.

RESUMO

Modelo do estudo: relato de caso Importância do problema: A tuberculose é um grave problema de saúde no nosso país, no entanto poucos profissionais sabem identificar as formas extrapulmonares da doença, que são responsáveis por 23,3% dos óbitos por tuberculose no Brasil. Das formas extra-pulmonares, apenas 1-2% representam formas cutâneas. É importante que o médico generalista conheça as formas cutâneas de tuberculose, uma vez que pode ser a única manifestação da doença. O seu diagnóstico é um desafio, pois os exames tradicionais têm menor sensibilidade e especificidade para a apresentação cutânea em relação à forma pulmonar. No entanto, novos exames vêm sendo implantados como o GeneXpert. Comentários: Relatamos um caso raro de tuberculose cutânea em paciente imunocompetente, com a manifestação de três formas clínicas simultaneamente ­ escrofuloderma, tubercúlide papulonecrótica e eritema indurado de Bazin. A ocorrência de duas formas simultâneas é descrita na literatura mas a ocorrência de três formas simultâneas é inédita. Essa manifestação atípica foi de difícil diagnóstico clínico por simular outras doenças e os exames tradicionais como o RX de tórax, baciloscopia e cultura não evidenciaram o diagnóstico. A identificação do Mycobacterium tuberculosis só foi possível por meio da pesquisa de PCR com o GeneXpert, que mostrou positividade no escarro pulmonar e no exsudato do escrofuloderma, possibilitando iniciar o tratamento precocemente. Este novo exame de alta sensibilidade e especificidade no diagnóstico da tuberculose pulmonar mostrou-se de grande utilidade no diagnóstico deste caso atípico de tuberculose cutânea onde os exames tradicionais não definiram o diagnóstico.

Study: Case Report Importance: Tuberculosis is a serious health problem in Brazil. Nevertheless, only few physicians know how to identify the non-pulmonary cases of this disease, which can represent up to 23,3% of deaths caused by tuberculosis in Brazil. Among the non-pulmonary cases, only 1-2% affect the skin. It is important for the general physician to understand the cutaneous presentations of tuberculosis, once it can be the only symptom that the patient presents. Diagnosing cutaneous tuberculosis is a challenge, because traditional laboratory tests have smaller sensitivity and specificity for the cutaneous form in contrast to pulmonary tuberculosis. However, implementation of new exams such as GeneXpert may come in hand. Comments: We report a rare case of cutaneous tuberculosis on an immunocompetent patient, with three different simultaneous presentations - scrofuloderma, papulonecrotic tuberculids and Bazin's indurated erythema. Occurrence of two simultaneous presentations has been reported, however, three simultaneous forms have not. Diagnosing this atypical manifestation was very hard because the clinical presentation often mimics other dermatological conditions, and traditional laboratory testing such as chest X-ray, bacilloscopy and culture did not evidence infection. Identification of Mycobacterium tuberculosis was only possible due to positive PCR testing through GeneXpert on pulmonary and scrofuloderma fluids, allowing rapid treatment initiation. This new high sensitivity and specificity exam proved to be of great value when diagnosing this atypical cutaneous tuberculosis case, in which diagnose was not possible through traditional laboratory testing.

RESUMO

[ABSTRACT]. Objective. To identify individual- and health services–related factors associated with deaths in subjects diagnosed with tuberculosis (TB). Methods. A nonconcurrent cohort study with passive follow-up was conducted using a probabilistic linkage method to analyze a sample of patients diagnosed and reported as having TB in 2006 and followed up until 2008. New cases, cases with previous treatment (readmission after loss to follow-up or relapse), and transfers across health services were included. Proportional hazards models were used to estimate the independent effect of covariates related to the individual and to the health services on mortality from all causes. Results. Age above 60 years, admission to a hospital with emergency services, HIV-associated TB, and readmission to an outpatient facility after disease relapse or loss to follow-up were identified as risk factors for death. Variables related to process and results indicators of Brazil’s National TB Program were not associated with mortality from all causes. Conclusions. Advanced age, previous treatment for TB, and treatment at a secondary-level outpatient facility or a hospital with emergency services on site were associated with mortality in TB patients. Better strategies to improve TB care delivered at health units are needed to prevent death from TB, especially among the elderly.

[RESUMEN]. Objetivo. Identificar los factores individuales y los factores relacionados con los servicios de salud asociados con la muerte de personas con diagnóstico de tuberculosis. Métodos. Se realizó un estudio de cohortes no concurrentes con seguimiento pasivo, con un método de nexo probabilístico, para analizar una muestra de pacientes a quienes se les diagnosticó tuberculosis y se notificaron sus casos en el 2006, y se les dio seguimiento hasta el 2008. Se incluyeron casos nuevos, casos con tratamiento anterior (reingreso después de haber abandonado el seguimiento o por recaída) y transferencias entre distintos servicios de salud. Se usaron modelos de riesgos proporcionales para calcular el efecto independiente de las covariables relacionadas con los individuos y con los servicios de salud en la mortalidad por todas las causas. Resultados. Se determinó que los factores de riesgo de muerte son: edad mayor de 60 años, ingreso a un hospital con servicios de urgencia, tuberculosis asociada con la infección por el VIH y reingreso a un establecimiento de atención ambulatoria después de la recaída de la enfermedad o de abandonar el seguimiento. Las variables relacionadas con los procesos y los indicadores de resultados del Programa Nacional contra la Tuberculosis de Brasil no se asociaron con la mortalidad por todas las causas. Conclusiones. La edad avanzada, el antecedente de tratamiento antituberculoso y el tratamiento en un establecimiento ambulatorio de nivel secundario o un hospital con servicios integrados de urgencia se asociaron con la mortalidad de los pacientes con tuberculosis. Se necesitan mejores estrategias para optimizar los servicios de atención de la tuberculosis que prestan las unidades de salud a fin de evitar la muerte por esta enfermedad, especialmente en las personas de mayor edad.

Variáveis de processo e indicadores de resultados do Programa Nacional de Controle da Tuberculose não guardaram relação com a mortalidade por todas as causas. Conclusões. Idade avançada, tratamento prévio da TB e tratamento em unidade ambulatorial de nível secundário ou em hospital com serviço de emergência no local apresentaram associação com mortalidade em pacientes com TB. São necessárias estratégias melhores para aprimorar a atenção à TB ofertada nas unidades de saúde, principalmente para idosos.

RESUMO

OBJECTIVE: This prospective clinical trial aimed to assess clinical and patient-reported outcomes of the single-implant mandibular overdenture treatment (SIMO) after a 2-year follow-up period. MATERIALS AND METHODS: An external hexagon implant was inserted in the mandibular midline of 45 complete denture wearers. Participants had a mean age of 63.4 (SD = 8.3), and 75.6% were female. Based on the primary stability of the implant, immediate loading was performed in 38 patients (84.4%). O'ring/ball attachments were used for retention. Outcome assessment included the participants' satisfaction with the dentures and oral health-related quality of life (OHRQoL) impacts at the 3-, 6-, 12-, and 24-month follow-up visits after implant loading. Moreover, all prosthodontic events were recorded during this period. RESULTS: The post-loading implant survival rate was 95.3%. There was a significant increase in satisfaction with the mandibular overdenture (p < .001) and a decrease in the overall OHRQoL impacts (p < .001) in the 3-month follow-up. No significant changes were observed between the 3- and 24-month follow-ups. The incidence of prosthodontic events was relatively high, including the need for matrix replacement and repair of the overdenture fracture. Most prosthodontic complications were minor and properly managed in periodic recall visits. CONCLUSIONS: Single-implant mandibular overdenture is a feasible alternative for subjects poorly adapted to the mandibular denture and resulted in significant improvement in patient satisfaction and quality of life measures. A careful selection of patients based on their demanding needs and expectations is essential to indicate this alternative. The incidence of maintenance events in the long term reinforces the need for periodical clinical monitoring.

Resultados Idade maior de 60 anos, admissão em hospital com serviço de emergência, coinfecção HIV/TB e reingresso a um serviço ambulatorial após recorrência da TB ou perda de seguimento foram identificados como fatores de risco para a morte. Variáveis de processo e indicadores de resultados do Programa Nacional de Controle da Tuberculose não guardaram relação com a mortalidade por todas as causas. Conclusões Idade avançada, tratamento prévio da TB e tratamento em unidade ambulatorial de nível secundário ou em hospital com serviço de emergência no local apresentaram associação com mortalidade em pacientes com TB. São necessárias estratégias melhores para aprimorar a atenção à TB ofertada nas unidades de saúde, principalmente para idosos.

RESUMO

INTRODUCTION: Road traffic crashes (RTC) are an important public health problem, accounting for 1.2 million deaths per year worldwide. In Brazil, approximately 40,000 deaths caused by RTC occur every year, with different trends in the Federal Units. However, these figures may be even greater if health databases are linked to police records. In addition, the linkage procedure would make it possible to qualify information from the health and police databases, improving the quality of the data regarding underlying cause of death, cause of injury in hospital records, and injury severity. OBJECTIVE: This study linked different data sources to measure the numbers of deaths and serious injuries and to estimate the percentage of corrections regarding the underlying cause of death, cause of injury, and the severity injury in victims in matched pairs from record linkage in five representative state capitals of the five macro-regions of Brazil. METHODS: This cross-sectional, population-based study used data from the Hospital Information System (HIS), Mortality Information System (MIS), and Police Road Traffic database of Belo Horizonte, Campo Grande, Curitiba, Palmas, and Teresina, for the year 2013 for Teresina, and 2012 for the other capitals. RecLink III was used to perform probabilistic record linkage by identifying matched pairs to calculate the global correction percentage of the underlying cause of death, the circumstance that caused the road traffic injury, and the injury severity of the victims in the police database. RESULTS: There was a change in the cause of injury in the HIS, with an overall percentage of correction estimated at 24.4% for Belo Horizonte, 96.9% for Campo Grande, 100.0% for Palmas, and 33.2% for Teresina. The overall percentages of correction of the underlying cause of death in the MIS were 29.9%, 11.9%, 4.2%, and 33.5% for Belo Horizonte, Campo Grande, Curitiba, and Teresina, respectively. The correction of the classification of injury severity in police database were 100.0% for Belo Horizonte and Teresina, 48.0% for Campo Grande, and 51.4% for Palmas after linkage with hospital database. The linkage between mortality and police database found a percentage of correction of 29.5%, 52.3%, 4.4%, 74.3 and 72.9% for Belo Horizonte, Campo Grande, Palmas, Curitiba and Teresina, respectively in the police records. CONCLUSIONS: The results showed the importance of linking records of the health and police databases for estimating the quality of data on road traffic injuries and the victims in the five capital cities studied. The true causes of death and degrees of severity of the injuries caused by RTC are underestimated in the absence of integration of health and police databases. Thus, it is necessary to define national rules and standards of integration between health and traffic databases in national and state levels in Brazil.

RESUMO

Lymphomatoid papulosis (LyP) is defined as a chronic, recurrent, self-healing papulonecrotic or papulonodular skin disease with histologic features suggestive of a (CD30-positive) malignant lymphoma. In up to 20% of patients, LyP are preceded by, associated with, or followed by another type of cutaneous or systemic lymphoma, generally mycosis fungoides (MF), primary cutaneous anaplastic large cell lymphoma (C-ALCL). In this case, we describe a case of MF that preceded and continued to coexist with LyP type C.(AU)

RESUMO

Aplasia cutis congenita (ACC) is a rare disease characterized by congenital absence of skin, affecting preferentially the scalp. Diagnosis is made clinically; however, recent studies have shown that dermoscopy can be a useful tool for the diagnosis and differentiation from sebaceous nevus. The clinical findings include a shiny atrophic alopecic patch associated with dermoscopic findings of absent follicular openings, thicker vessels and a distinct collar hypertrichosis. We report 2 cases of alopecia presenting from birth. At dermoscopy, the absence of follicular openings and the increase in the caliber of vessels led us to establish the diagnosis of ACC.

RESUMO

The article discusses psychology training in health care at the Federal University of São Paulo. It places curriculum guidelines in a changing movement of training for health professions, proposing Work in Health Care as one of its common axes. In the Baixada Santista campus, the course is based on learning by experience, public health services and multidisciplinary team work. Three vectors derived from the experience in this project and its assessment are discussed: a common clinic, work in health care as an ethics and the idea of good training by insufficiency.

RESUMO

STUDY OBJECTIVE: An association between rapid repeat pregnancy (RRP; occurring within a birth interval of up to 24 months) and undesirable obstetric and perinatal outcomes has been shown, especially among adolescents and women without adequate schooling. The objective of this study was to evaluate the effect of the interaction between maternal schooling and age on the incidence of RRP. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A nonconcurrent cohort study was carried out using probabilistic record linkage techniques. The 59,400 linked records of singleton live-born infants delivered in 2002 whose mothers were up to 29 years old and lived in Rio de Janeiro City were evaluated. RESULTS: Compared with young adults with adequate schooling, the adjusted risk ratio for RRP for adolescents with inadequate schooling was 2.1 (95% confidence interval, 1.8-2.4). The attributable proportion was 0.16 (95% confidence interval, 0.02-0.29). CONCLUSION: Young maternal age and inadequate schooling interact, increasing RRP.

RESUMO

BACKGROUND: Blood pressure (BP) variability is associated with target organ damage in hypertension and diabetes. The 24 h ambulatory blood pressure monitoring (24 h-ABPM) has been proposed as an evaluation for BP variability using several indexes [standard deviation (SD) of mean BP, coefficient of variation (CV), BP variation over time (time-rate index)]. METHODS: We evaluated the association between BP variability measured by 24 h-ABPM indexes and echocardiographic variables in a cross-sectional study in 305 diabetic-hypertensive patients. RESULTS: Two groups were defined by the median (0.55 mmHg/min) of time-rate systolic BP (SBP) index and classified as low or high variability. Age was 57.3 ± 6.2 years, 196 (64.3%) were female. Diabetes duration was 10.0 (5.0-16.2) years, HbA1c was 8.2 ± 1.9%. Baseline clinical characteristics were similar between low (n = 148) and high (n = 157) variability groups. Office SBP and systolic 24 h-ABPM were higher in the high variability group (139.9 mmHg vs 146.0 mmHg, P = 0.006; 128.3 mmHg vs 132.9 mmHg, P = 0.019, respectively). Time-rate index, SD and CV of SBP, were higher in high variability group (P < 0.001; P < 0.001 and P = 0.003, respectively). Time-rate index was not independently associated with the echocardiography's variables in multiple linear model when adjusting for age, 24 h-ABPM, diabetes duration and HbA1c. The multiple linear regression model revealed that the significant and independent determinants for septum thickness, relative wall thickness and posterior wall thickness (parameters of left ventricular hypertrophy) were: age (p = 0.025; p = 0.010; p = 0.032, respectively) and 24 h-SBP (p < 0.001 in the three parameters). CONCLUSION: BP variability estimated by 24 h-ABPM is not independently associated with echocardiographic parameters in diabetic-hypertensive patients.
