Diagnóstico precoce da neuropatia diabética e profilaxia do pé diabético

Introduction: the diabetic foot is one of the most serious complications of diabetes mellitus. About 50% of non-traumatic amputations occur in these patients. In addition, it is an important public health problem and constitutes a chronic and complex metabolic disorder that is characterized by impaired metabolism of glucose and other complications in essential organs for the maintenance of life. Objective: to evaluate the sensitivity and specificity of diabetic neuropathy using the Michigan self-assessment and physical examination in type 1 and type 2 diabetics. Methods: this is a cross-sectional study. The “Michigan Neuropathy Screening Instruments” classification was used to assess the degree of peripheral neuropathy, in which participants answered the questionnaire and were evaluated for the presence of foot lesions. All participants were stratified by the risk of developing foot ulcers according to the IWGDF protocol. Results: the sample had 200 participants. Regarding the IWGDF classification, 23 patients were classified as moderate risk (11.50%) and 61 as high risk for developing foot ulcers (30.50%). Using a cutoff of 2.5 on the physical examination score to diagnose neuropathy, a sensitivity of 97.62% and a specificity of 47.41% were obtained. Using a score greater than or equal to 6 in the self-assessment for the diagnosis of neuropathy, a sensitivity of 50.00% and a specificity of 94.83% were found. Conclusion: the association of the Michigan physical examination (high sensitivity) with self-assessment (high specificity) increases the accuracy for the diagnosis of diabetic neuropathy.Introdução: o pé diabético é uma das complicações mais sérias do diabetes mellitus. Cerca de 50% das amputações não traumáticas ocorrem nesses pacientes. Além disso, é um importante problema de saúde pública por ser um distúrbio metabólico crônico e complexo que se caracteriza pelo comprometimento do metabolismo da glicose associada a outras complicações em órgãos essenciais para manutenção vital. Objetivo: avaliar a sensibilidade e especificidade para neuropatia diabética da autoavaliação e do exame físico de Michigan nos diabéticos tipo 1 e tipo 2. Método: trata-se de um estudo transversal. Foi utilizada a classificação “Michigan Neuropathy Screening Instruments” para avaliação do grau de neuropatia periférica, em que os participantes responderam ao questionário e foram avaliados quanto a presença de lesões nos pés. Todos os participantes foram estratificados quanto ao risco de desenvolver úlcera nos pés de acordo com o protocolo do IWGDF. Resultados: a amostra contou com 200 participantes. Quanto à classificação do IWGDF, 23 pacientes foram classificados como risco moderado (11,50%) e 61 como alto risco para o desenvolvimento de úlceras nos pés (30,50%). Utilizando-se um corte de 2,5 na pontuação do exame físico para diagnosticar a neuropatia, foi obtida uma sensibilidade de 97,62% e uma especificidade de 47,41%. Utilizando-se uma pontuação maior ou igual a 6 na autoavaliação para o diagnóstico de neuropatia, foi obtida uma sensibilidade de 50,00% e uma especificidade de 94,83%. Conclusão: a associação do exame físico de Michigan (alta sensibilidade) com a autoavaliação (alta especificidade) tem melhor acurácia para o diagnóstico de neuropatia diabética

Carbonyl Compounds Generated from Electronic Cigarettes

Electronic cigarettes (e-cigarettes) are advertised as being safer than tobacco cigarettes products as the chemical compounds inhaled from e-cigarettes are believed to be fewer and less toxic than those from tobacco cigarettes. Therefore, continuous careful monitoring and risk management of e-cigarettes should be implemented, with the aim of protecting and promoting public health worldwide. Moreover, basic scientific data are required for the regulation of e-cigarette. To date, there have been reports of many hazardous chemical compounds generated from e-cigarettes, particularly carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, and glyoxal, which are often found in e-cigarette aerosols. These carbonyl compounds are incidentally generated by the oxidation of e-liquid (liquid in e-cigarette; glycerol and glycols) when the liquid comes in contact with the heated nichrome wire. The compositions and concentrations of these compounds vary depending on the type of e-liquid and the battery voltage. In some cases, extremely high concentrations of these carbonyl compounds are generated, and may contribute to various health effects. Suppliers, risk management organizations, and users of e-cigarettes should be aware of this phenomenon

ObjectReal-world data from wearable devices has the potential to understand mental health status in everyday life. We aimed to investigate the feasibility of estimating mental health status using a wrist-worn wearable device (Fitbit Sense) that measures movement using a 3D accelerometer and optical pulse photoplethysmography (PPG).MethodsParticipants were 110 patients with mental illnesses from different diagnostic groups. The study was undertaken between 1 October 2020 and 31 March 2021. Participants wore a Fitbit Sense on their wrist and also completed the State–Trait Anxiety Inventory (STAI), Positive and Negative Affect Schedule (PANAS), and EuroQol 5 dimensions 5-level (EQ-5D-5L) during the study period. To determine heart rate (HR) variability (HRV), we calculated the sdnn (standard deviation of the normal-to-normal interval), coefficient of variation of R-R intervals, and mean HR separately for each sleep stage and the daytime. The association between mental health status and HR and HRV was analyzed.ResultsThe following significant correlations were found in the wake after sleep onset stage within 3 days of mental health status assessment: sdnn, HR and STAI scores, HR and PANAS scores, HR and EQ-5D-5L scores. The association between mental health status and HR and HRV was stronger the closer the temporal distance between mental health status assessment and HR measurement.ConclusionA wrist-worn wearable device that measures PPG signals was feasible for use with patients with mental illness. Resting state HR and HRV could be used as an objective assessment of mental health status within a few days of measurement.</p
