RESUMEN
Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent psychiatric condition characterized by developmentally inappropriate symptoms of inattention and/or hyperactivity/impulsivity, which leads to impairments in the social, academic, and professional contexts. ADHD diagnosis relies solely on clinical assessment based on symptom evaluation and is sometimes challenging due to the substantial heterogeneity of the disorder in terms of clinical and pathophysiological aspects. Despite the difficulties imposed by the high complexity of ADHD etiology, the growing body of research and technological advances provide good perspectives for understanding the neurobiology of the disorder. Such knowledge is essential to refining diagnosis and identifying new therapeutic options to optimize treatment outcomes and associated impairments, leading to improvements in all domains of patient care. This review is intended to be an updated outline that addresses the etiological and neurobiological aspects of ADHD and its treatment, considering the impact of the "omics" era on disentangling the multifactorial architecture of ADHD.
RESUMEN
BACKGROUND AND AIMS: Estimated glomerular filtration rate (eGFR) equations accuracy has been questioned in diabetes mellitus (DM). We aimed to evaluate the performance of three equations - European Kidney Function Consortium (EKFC), Full Age Spectrum (FAS), and 2021 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) - in healthy and type 2 DM participants. MATERIAL AND METHODS: This cross-sectional studycompared eGFR equations withareference method: measured GFR (mGFR) by 51Cr-EDTA. The equations performance was assessed usingBland-Altman plot,concordance correlation coefficient (CCC), bias,P30 andP15 accuracy. RESULTS: In the 100 healthy adults included (aged 39 ± 15 years, 67% women, mean mGFR 107 ± 15, 2021 CKD-EPI 109 ± 14, FAS 107 ± 18 and EKFC 101 ± 12 mL/min/1.73 m2), all equations reached P30 accuracy above the desirable benchmark of 90%. In the 122 patients with type 2 DM (aged 61 ± 10 years, 55% women, mGFR97 ± 22, 2021 CKD-EPI 86 ± 20, FAS 83 ± 25 and EKFC 79 ± 18 mL/min/1.73 m2), the equations presented larger biases, worst agreement with mGFR and inferior accuracy, with 2021 CKD-EPI (83%) and EKFC (82%) presenting greater P30 than FAS (77%). CONCLUSION: In healthy Brazilian adults, 2021 CKD-EPI, FAS and EKFC are suitable to estimate GFR. However, all equations underperform in people with type 2 DM.
