High-quality evidence shows that alemtuzumab, natalizumab and ocrelizumab present the highest efficacy among DMTs, and other meta-analyses are required regarding adverse events frequency, to better understand the safety of therapies. Based on efficacy profile, guidelines should consider a three-category classification (i.e. high, intermediate and low efficacy).

Our results suggest an association between the use of benzodiazepines and the development of dementia. However, the current evidence lacks the power to infer differences between the effects of Alzheimer's disease and vascular dementias, long-acting and short-acting benzodiazepines, and various exposure loads (duration and dose). Future long-term prospective cohort studies are necessary, with adequate adjustments for confounding variables, strategies to minimize reverse causality, reporting of subgroups aimed at greater homogeneity of findings, adequate statistical power to identify high-magnitude effects, and defined daily dose analyses for dose-response gradient.

Non-adherence to recommended treatment can lead to negative outcomes, such as inefficiency (using dosages lower than prescribed), poisoning (using dosages higher than prescribed), and other adverse reactions.

Objectives: this observational study aimed to describe the discrepancies identified during medication reconciliation on patient admission to cardiology units in a large hospital.Methods: the medication history of patients was collected within 48 hours after admission, and intentional and unintentional discrepancies were classified as omission, duplication, dose, frequency, timing, and route of drug administration. Results: most of the patients evaluated were women (58.0%) with a mean age of 59 years, and 75.5% of the patients had a Charlson comorbidity index score between 1 and 3. Of the 117 discrepancies found, 50.4% were unintentional. Of these, 61.0% involved omission, 18.6% involved dosage, 18.6% involved timing, and 1.7% involved the route of drug administration. Conclusion: this study revealed a high prevalence of discrepancies, most of which were related to omissions, and 50% were unintentional. These results reveal the number of drugs that are not reincorporated into the treatment of patients, which can have important clinical consequences.
