Perfil epidemiológico do câncer infantil em população atendida por uma unidade de oncologia pediátrica em Salvador-Bahia
Childhood cancer is a rare event. It is represents about 1% of all diagnosed cancer in developing countries. Planning of preventive actions requires epidemiological investigations in different geographic areas, which ones are still insufficient, to the disease's definition of occurrence, distribution and risk factors. This study has described the epidemiological profile of childhood cancer in a pediatric oncology institution in Salvador. Prompter of patients, who were accepted in institution from 1995 to 2003, have taken to the study. From 465 investigated patients, 57,8% were boys, 50,8% were brown and 40,1% were born in Salvador's metropolitan area. The most frequent cancer were leukemias, followed by lymphomas and osteosarcomas, 39,5%, 18,9% and 9,9%, respectively. The most important causes of death were, in decreasing order: leukemias, osteosarcomas, lymphomas and neuroblastomas. The global survival rates in the period has represented 51% of investigated population, the number of deaths, 38,3% and the number of treatment abandoning, 2,4%. In 21% of cases, it was related other cases of cancer in family and in 4%, it was registered preview exposure to any kind of toxic substance. However, the analysis of probable risk factors associated to development of cancer was impaired due to the absence of registry of these aspects in most of investigated prompter. Other studies about this theme are necessary to contribute to epidemiology of childhood cancer and are important to associate possible risk factors in specific geographic areas.O câncer na infância é um evento raro, que representa cerca de 1% das neoplasias diagnosticadas nos países em desenvolvimento. O planejamento de medidas preventivas requer estudos epidemiológicos em diferentes áreas geográficas, os quais ainda são insuficientes para a definição de ocorrência, distribuição e fatores de risco da doença. Este trabalho descreve o perfil epidemiológico do câncer infantil em uma unidade de oncologia pediátrica de Salvador. Foram tomados para o estudo os prontuários dos pacientes admitidos na instituição no período de 1995 a 2003. Dos 465 pacientes estudados, 57,8% eram do sexo masculino, 50,8% eram pardos e 40,1% eram naturais da Região Metropolitana de Salvador. Os tipos de câncer mais freqüentes foram as leucemiùs, seguidas pelos linfomas e osteossarcomas, 39,5%, 18,9% e 9,9% respectivamente. Como principais causas de óbito, destacaram-se, em ordem decrescente: leucemias, osteossarcomas, linfomas e neuroblastoma. A sobrevida global livre de doença no período representou 51% da população estudada, o número de óbitos 38,3% e o número de abandonos de tratamento, 2,4%. Em 21% dos casos, havia relatos de outros casos de câncer na família e em 4% foi registrada exposição anterior a algum tipo de agente reconhecidamente tóxico. No entanto, a análise de possíveis fatores de risco associados ao desenvolvimento de neoplasias foi prejudicada em virtude da falta de registro desses aspectos na maioria dos prontuários analisados. São necessários novos estudos sobre o tema, que possam contribuir para a epidemiologia do câncer infantil e associar possíveis fatores de risco em áreas geográficas específicas
Health-related quality of life in patients with type 1 diabetes mellitus in the different geographical regions of Brazil : data from the Brazilian Type 1 Diabetes Study Group
Background: In type 1 diabetes mellitus (T1DM) management, enhancing health-related quality of life (HRQoL) is as important as good metabolic control and prevention of secondary complications. This study aims to evaluate possible regional differences in HRQoL, demographic features and clinical characteristics of patients with T1DM in Brazil, a country of continental proportions, as well as investigate which variables could influence the HRQoL of these individuals and contribute to these regional disparities. Methods: This was a retrospective, cross-sectional, multicenter study performed by the Brazilian Type 1 Diabetes Study Group (BrazDiab1SG), by analyzing EuroQol scores from 3005 participants with T1DM, in 28 public clinics, among all geographical regions of Brazil. Data on demography, economic status, chronic complications, glycemic control and lipid profile were also collected. Results: We have found that the North-Northeast region presents a higher index in the assessment of the overall health status (EQ-VAS) compared to the Southeast (74.6 ± 30 and 70.4 ± 19, respectively; p < 0.05). In addition, North- Northeast presented a lower frequency of self-reported anxiety-depression compared to all regions of the country (North-Northeast: 1.53 ± 0.6; Southeast: 1.65 ± 0.7; South: 1.72 ± 0.7; Midwest: 1.67 ± 0.7; p < 0.05). These findings could not be entirely explained by the HbA1c levels or the other variables examined. Conclusions: Our study points to the existence of additional factors not yet evaluated that could be determinant in the HRQoL of people with T1DM and contribute to these regional disparities
Familial hypercholesterolaemia in children and adolescents from 48 countries: a cross-sectional study
Background: Approximately 450 000 children are born with familial hypercholesterolaemia worldwide every year, yet only 2·1% of adults with familial hypercholesterolaemia were diagnosed before age 18 years via current diagnostic approaches, which are derived from observations in adults. We aimed to characterise children and adolescents with heterozygous familial hypercholesterolaemia (HeFH) and understand current approaches to the identification and management of familial hypercholesterolaemia to inform future public health strategies. Methods: For this cross-sectional study, we assessed children and adolescents younger than 18 years with a clinical or genetic diagnosis of HeFH at the time of entry into the Familial Hypercholesterolaemia Studies Collaboration (FHSC) registry between Oct 1, 2015, and Jan 31, 2021. Data in the registry were collected from 55 regional or national registries in 48 countries. Diagnoses relying on self-reported history of familial hypercholesterolaemia and suspected secondary hypercholesterolaemia were excluded from the registry; people with untreated LDL cholesterol (LDL-C) of at least 13·0 mmol/L were excluded from this study. Data were assessed overall and by WHO region, World Bank country income status, age, diagnostic criteria, and index-case status. The main outcome of this study was to assess current identification and management of children and adolescents with familial hypercholesterolaemia. Findings: Of 63 093 individuals in the FHSC registry, 11 848 (18·8%) were children or adolescents younger than 18 years with HeFH and were included in this study; 5756 (50·2%) of 11 476 included individuals were female and 5720 (49·8%) were male. Sex data were missing for 372 (3·1%) of 11 848 individuals. Median age at registry entry was 9·6 years (IQR 5·8-13·2). 10 099 (89·9%) of 11 235 included individuals had a final genetically confirmed diagnosis of familial hypercholesterolaemia and 1136 (10·1%) had a clinical diagnosis. Genetically confirmed diagnosis data or clinical diagnosis data were missing for 613 (5·2%) of 11 848 individuals. Genetic diagnosis was more common in children and adolescents from high-income countries (9427 [92·4%] of 10 202) than in children and adolescents from non-high-income countries (199 [48·0%] of 415). 3414 (31·6%) of 10 804 children or adolescents were index cases. Familial-hypercholesterolaemia-related physical signs, cardiovascular risk factors, and cardiovascular disease were uncommon, but were more common in non-high-income countries. 7557 (72·4%) of 10 428 included children or adolescents were not taking lipid-lowering medication (LLM) and had a median LDL-C of 5·00 mmol/L (IQR 4·05-6·08). Compared with genetic diagnosis, the use of unadapted clinical criteria intended for use in adults and reliant on more extreme phenotypes could result in 50-75% of children and adolescents with familial hypercholesterolaemia not being identified. Interpretation: Clinical characteristics observed in adults with familial hypercholesterolaemia are uncommon in children and adolescents with familial hypercholesterolaemia, hence detection in this age group relies on measurement of LDL-C and genetic confirmation. Where genetic testing is unavailable, increased availability and use of LDL-C measurements in the first few years of life could help reduce the current gap between prevalence and detection, enabling increased use of combination LLM to reach recommended LDL-C targets early in life
Health-related quality of life in patients with type 1 diabetes mellitus in the different geographical regions of Brazil: data from the Brazilian Type 1 Diabetes Study Group
Causes of renal failure in patients with decompensated cirrhosis and its impact in hospital mortality
Background. Renal failure (RF) is reported to occur in 11-49% of the patients with decompensated end-stage liver disease (ESLD) and has been associated with increased mortality, particularly in the occurrence of hepatorenal syndrome (HRS) type 1. Aims. To evaluate the frequency and outcome of RF in patients admitted to the hospital due to decompensated ESLD and to assess the impact of the underlying cause of RF on survival.Material and methods. Four hundred and six patients (65% males, mean age 62 ± 12 years) with decompensated ESLD were evaluated for the occurrence of RF (defined as serum creatinine 3 1.5 mg/mL). The underlying cause of RF was reckoned in each subject and compared to outcome.Results. Renal failure was observed in 39% of the patients at admission and in 10% of the subjects during hospitalization. Mortality was significantly higher in subjects with RF (26 vs. 1%, p < 0.000001). Hypovolemia, bacterial infections, parenchymal kidney diseases and HRS were identified as causes of RF in, respectively, 40, 32, 15 and 12% of the cases. Mortality was significantly higher in those subjects with HRS type 1 and bacterial infections, when compared to other causes of RF.Conclusions. Renal failure occurs in nearly half of the patients with decompensated ESLD. It is most commonly caused by hypovolemia and bacterial infections. Occurrence of RF has an adverse impact in patient survival, particularly in those subjects with bacterial infections and HRS type 1, prone to develop progressive renal dysfunction despite intensive medical care
