{"title":"Oral atenolol compared to oral propranolol for infantile hemangioma","authors":"Victor Meza Viteri, Ligia Aranibar","doi":"10.5867/medwave.2023.11.2753","DOIUrl":"https://doi.org/10.5867/medwave.2023.11.2753","url":null,"abstract":"Introduction Infantile hemangioma is the most frequent benign vascular tumor in childhood, with an incidence of 3 to 10%. When patients require treatment, oral propranolol, a non-selective lipophilic beta-blocker, is usually considered the therapy of choice. However, its use has been associated with several adverse events related to its β-2 action and its ability to cross the blood-brain barrier. Because of this, oral atenolol, a hydrophilic β-1 receptor-selective beta-blocker, may represent a valid treatment alternative. Nonetheless, there is still controversy regarding the efficacy and safety of atenolol when compared with propranolol as monotherapy for this condition. Methods We searched Epistemonikos, the largest database of systematic reviews in health science, which is maintained by screening multiple sources of information, including MEDLINE/PubMed, EMBASE, and Cochrane, among others. Data were extracted from the identified reviews, data from the primary studies were analyzed, a meta-analysis was performed, and a summary table of the results was prepared using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. Results Nine systematic reviews were identified, including 10 primary studies and three randomized trials. The three randomized trials were included in the analysis of this investigation. Conclusion The use of oral atenolol compared with oral propranolol as monotherapies may result in little or no difference in terms of likelihood of complete remission, decrease in Hemangioma Activity Score, likelihood of post-treatment relapse, and risk of adverse events and severe adverse events, in infantile hemangioma (low certainty of evidence).","PeriodicalId":18597,"journal":{"name":"Medwave","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138590310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This type of research is an important tool to address the complexity of health sciences, allowing the understanding and integration of quantitative data with experience-based aspects. In this way, a broad and deep perspective of health problems is achieved, providing a solution to sanitary policies and services. During the development of mixed methods research, there are key stages where both approaches can be integrated depending on the objectives set by the investigators. Although mixed methods studies may differ widely, general models have been identified to guide the development of a single specific design.

This study aimed to validate the effectiveness of clinical simulation training in managing these situations. We conducted a narrative review of studies published between 2008 and 2022, collected from databases including Scopus, Sciencedirect, PubMed, Springer, Scielo, and Google Scholar. Data from studies that met our inclusion criteria were meticulously gathered and summarized. Our findings strongly emphasize that clinical simulation emerges as a highly effective tool in the training of healthcare professionals. This training translates into substantial improvements in various aspects, including performance, knowledge, confidence, satisfaction, attitudes, self-efficacy, teamwork abilities, and the skills necessary to confront critical obstetric situations such as postpartum hemorrhage, eclampsia, shoulder dystocia, maternal cardiac arrest, umbilical cord prolapse, and cesarean sections. Importantly, this training reduces the inherent risks associated with learning on real patients and aligns with the highest ethical standards. Additionally, our results underscore that interdisciplinary collaboration in the management of obstetric emergencies proves to be an effective strategy for providing comprehensive patient care. However, it is crucial to highlight that, in order to ensure patient safety and promote a teamwork approach, it is imperative for healthcare professionals to receive adequate training and be duly qualified. Although we acknowledge that implementing clinical simulation training can entail significant costs and require substantial resources, we firmly believe that this strategy continues to hold immeasurable value in the education of professionals in this field. Ultimately, we anticipate that future high-quality research will further fortify the evidence base regarding best practices in clinical simulation training for obstetric emergencies, thus contributing to enhanced patient outcomes and the overall quality of healthcare in this critical domain.</p>","PeriodicalId":18597,"journal":{"name":"Medwave","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71434400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
