Objective: Analyzing studies related to Adverse Drug Events (ADE) in hospitalized patients in Brazil. Method: integrative review, for which the National Library of Medicine (PubMed), Biblioteca Virtual de Saúde (BVS), Repository of the Fundação Oswaldo Cruz (FIOCRUZ) and Capes Journals databases were selected for searching the studies primary, with the descriptors: Patient Safety, Drug-related side effects and adverse reactions, Patient harm, Hospitalization, Inpatients. Results: Twenty articles were identified, 50% (10) were from the southeast region of Brazil. Regarding the methodology adopted to identify the ADEs, 70% (14) used the retrospective data review. The trackers were used in 5 (25%) articles, 3 of which used the triggers proposed by the Institute for Healthcare Improvement, and the other 2 the trackers used were proposed by the researchers themselves. The number of adverse drug reactions ranged from 12 to 96, while the occurrence of AE ranged from 4 to 122. In one study 50% (41) of participants had at least one adverse drug event. Conclusion: There is great variability in scientific production in Brazil, and in the occurrence of Adverse Drug Events as well. There is a need for strategies to identify these events and create strategies to promote patient safety.

Objective: Evaluate trigger accuracy for identifying adverse drug events (ADEs) in hospitalised elderly. Methods: Two hundred patients 60 years old from a medical clinic within a private hospital were followed-up. For ADE identification the adapted Global Trigger Tool tracker methodology was used. Causality was determined using the Naranjo Algorithm. Results: Of the 200 elderly patients included in the study, 106 were females (53%), the average age was 79 years, and the average length of hospital stay was approximately ± 10 days. Selected triggers were identified 1,457 times. The group of triggers with the best performance regarding its analysis accuracy was evolution triggers, with sensitivity of 69% and positive predictive value of 68%. In the individual performance analysis, the evolution tracker allergy, allergic reaction, pruritus achieved 100% performance for both sensitivity and positive predictive value. A total of 165 ADs were identified. Of these, 18% were phlebitis and 16% were hypoglycaemia. Drugs associated with ADE included insulin (15%) and Clarithromycin (9%). Conclusion: The triggering methodology has been effective for identifying ADEs. In addition, determination best trigger for constructing an ADE identification tool for hospitalised elderly was performed.

Objective: To verify the relationship between obesity and the occurrence of negative outcomes in hospitalized patients. Methodology: An integrative review was carried out using the National Library of Medicine of the National Institutes of Health (PubMed) and the Virtual Health Library (VLH/BVS) database. Results: It was observed that obese patients are 2 to 5 times more likely to need Invasive Mechanical Ventilation (IMV) when admitted to the Intensive Care Unit. Patients with high BMI (obese) and who needed mechanical ventilation had a mortality rate above 60%. The risk increases as the patient has other pathologies, this fact is shown that mortality by COVID-19 has multifactorial causes. Conclusion: The study showed that obesity is a risk factor associated with the increased development of the severe form of the disease, usually associated with other pathologies (hypertension, diabetes and cardiovascular diseases). That is, obesity increases the likelihood of unfavorable outcomes.

Objectives: This study set out to determine whether there are any correlations between lipid and glucose levels and oxidative stress presented by elderly patients with and without nontransmissible chronic diseases (NTCDs). Methods: Serum biochemical concentrations of lipoproteins, glucose and oxidative stress markers (malondialdehyde and nitric oxide) were determined in 44 elderly patients (22 elderly people without NTCDs and 22 elderly people with NTCDs), aged between 60 and 81 years old. Results: The elderly people with NTCDs showed higher LDL concentrations, glucose, and oxidative stress markers than those without NTCDs. There was a positive and significant correlation between the levels of malondialdehyde with the abnormal lipid profile of the elderly without NTCDs and hyperglycaemia presented by elderly people with NTCDs. The total trolox equivalent antioxidant capacity had a negative correlation with the levels of malondialdehyde in the elderly without NTCDs. Another negative correlation was observed between the levels of nitric oxide and malondialdehyde in elderly people with NTCDs. Conclusion: Once oxidative stress and abnormal lipid profile have occurred in both groups, it is suggested that the hyperglycemia present in the group with chronic diseases has been determinant for the increase of the oxidative stress found in this group.

Objetivo: realizar uma síntese integrativa sobre as principais complicações hematológicas correlacionadas à COVID-19, com base na análise de artigos e dissertações que abordam a respeito do assunto. Metodologia: foram feitas diversas pesquisas de artigos publicados na íntegra, entre 2020 e 2021, nas bases de dados: Portal de periódicos da Capes; MEDLINE (Medical Literature Analysis and Retrieval System Online); SciELO (Scientific Electronic Library Online) e BVS (Biblioteca Virtual da Saúde); além das diretrizes do Ministério da Saúde (OMS) e os protocolos clínicos e terapêuticos desenvolvidos no Brasil. Após análise dos artigos, foram escolhidos 30 artigos como amostra final para estudo de revisão, além das diretrizes do Ministério da Saúde e outros órgãos mencionados. Resultados: a presente revisão possibilitou observar que, a maior parte dos pacientes que apresentaram casos graves da doença, desenvolveram alterações hematológicas importantes, como a diminuição significativa de plaquetas e lifócitos, aumento do dímero D e prolongamento do tempo de protrombina e tromboplastina. Esses fatores foram ligados a evolução de problemas cardiovasculares como o Tromboembolismo Venoso, Coagulação vascular intradisseminada, muitas vezes, levando o paciente a óbito. Conclusão: esta revisão fornece uma vasta visão da situação atual do COVID-19 durante o último ano e revela, explanando situações interligadas com sua fisiopatologia, manifestações clínicas, as principais características de alterações hematológicas e coagulopáticas observadas no diagnóstico e o impacto da pandemia no sistema de saúde mundial.
