Breast cancer is one of the most incident cancers and has been considered the leading cause of death for women worldwide. When it is restricted to a mumlobulum or duct it is defined as noninvasive breast cancer, such as ductal carcinoma in situ and lobular carcinoma in situ. On the other hand, when malignant cells extend to regions adjacent to or far from breast tissue, an invasive or metastatic breast cancer is characterized, such as infiltrated ductal and lobular carcinomas, mucinous carcinoma, and tubular carcinoma.
Acute myocardial infarction (AMI) is the syndrome with classical clinical manifestations, laboratory evidence of necrosis by ischemia of the heart muscle, and characteristic changes in electrocardiogram (ECG). AMI can be classified into several types according to electrocardiographic, pathophysiological, clinical, prognostic and etiological criteria, which is valid because it allows specific and more assertive interventions to be performed
Stroke is the second leading cause of death worldwide, including Brazil¹,2. It is a more common condition in the elderly, but it has an increasing prevalence in young adults due to the development of risk factors that were typically attributed to older ages3. Risk factors can be categorized into non-modifiable (race, ethnicity, gender and age) and modifiable (arterial hypertension, obesity, diabetes mellitus, smoking and alcoholism), both contributing to distinct trends in incidence and mortality from stroke4. There are two pathological subtypes of stroke, the hemorrhagic one that courses with intraparenchymal or subarachnoid hemorrhage, and the ischemic one that involves areas of cerebral, retinal and even spinal infarction5,6. Clinical syndromes and focal neurological deficits are determined by the affected vascular territory, a parameter that is also used to classify strokes, presume prognoses and determine more specific interventions
Infarto agudo do miocárdio (IAM) é um quadro de elevada prevalência, exige internação hospitalar e intervenção imediata, sendo considerado uma das principais causas de morbimortalidade em todo o mundo. O principal objetivo deste trabalho foi determinar o perfil epidemiológico do IAM no Rio Grande do Sul entre os anos de 2015 e 2019 através do cálculo da prevalência de internações hospitalares, taxas de mortalidade específica e proporcional. Trata-se de um estudo ecológico retrospectivo cuja busca de informações foi realizada em bases de dados disponíveis no Departamento de Informática do Sistema Único de Saúde. Evidenciou-se um aumento da prevalência de internações hospitalares simultâneo à redução das taxas de mortalidade por IAM. Com isso, supõe-se que o estado realizou um manejo eficiente dos pacientes que chegaram aos serviços de emergência,
Diabetes mellitus (DM) is a disease that courses with hyperglycemia and disorders of carbohydrate, lipid and protein metabolism. Epidemiological studies estimate that 1 in 11 adults (20 to 79 years old) had DM in 2015 and the prevalence of DM is expected to increase by 50% in the next 20 years, especially in developing countries. Knowing the mortality rates of a disease and its demographic distribution, in addition to the profile of hospital morbidity, allows the development of more efficient public policies and intervention strategies based on new studies. Considering the absence of articles on this topic, the importance of the present study is justified, whose objective was to conduct a longitudinal analysis of hospital morbidity and mortality from diabetes and its complications in Brazil between the years 2000 and 2020, based on information systems of SUS. Although the number of hospital admissions has decreased, the number of deaths has increased successively, which reveals a poor management of complications and severe cases. Thus, it is concluded that Brazil needs to invest in strategies for early and effective treatment of severe conditions, as well as in prevention measures to reduce the number of cases of diabetes and, consequently, the number of deaths as well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
