Repercussions of the Emergency neurological life support on scientific literature: a bibliometric study / Repercussões do Emergency neurological life support na literatura científica: um estudo bibliométrico

Abstract Background In 2012, the Neurocritical Care Society launched a compilation of protocols regarding the core issues that should be addressed within the first hours of neurological emergencies - the Emergency neurological life support (ENLS). Objective We aim to evaluate this repercussion through a bibliometric analysis. Methods We searched Scopus on October 2022 for articles mentioning ENLS. The following variables were obtained: number of citations; number of citations per year; number of publications per year; year of publication; research type; research subtype; country of corresponding author and its income category and world region; journal of publication and its 5-year impact factor (IF); and section where ENLS appeared. Results After applying eligibility criteria, we retrieved 421 articles, published from 2012 to 2022. The mean number of citations per article was 17.46 (95% Confidence Interval (CI) = 8.20-26.72), while the mean number of citations per year per article was 4.05 (95% CI = 2.50-5.61). The mean destiny journal 5-year IF was 5.141 (95% CI = 4.189-6.093). The majority of articles were secondary research (57.48%; n= 242/421) of which most were narrative reviews (71.90%; n= 174/242). High-Income countries were the most prominent (80.05%; n= 337/421 articles). There were no papers from low-income countries. There were no trials or systematic reviews from middle-income countries. Conclusion Although still low, the number of publications mentioning ENLS is increasing. Articles were mainly published in journals of intensive care medicine, neurology, neurosurgery, and emergency medicine. Most articles were published by authors from high-income countries. The majority of papers were secondary research, with narrative review as the most frequent subtype.

Resumo Antecedentes Em 2012, a Neurocritical Care Society lançou uma compilação de protocolos sobre as questões centrais que devem ser abordadas nas primeiras horas de emergências neurológicas - Emergency neurological life support (ENLS). Objetivo Avaliar a repercussão do ENLS por meio de uma análise bibliométrica. Métodos A base de dados Scopus foi utilizada em outubro de 2022 para a busca por artigos mencionando o ENLS. As seguintes variáveis foram obtidas: número de citações; número de citações por ano; número de publicações por ano; ano de publicação; tipo de pesquisa; país do autor correspondente e sua categoria de renda; revista de publicação e seu fator de impacto de 5 anos (IF); e seção onde o ENLS apareceu. Resultados Os 421 artigos incluídos foram publicados de 2012 a 2022. A média de citações por artigo foi de 17.46 (intervalo de confiança (IC) 95% = 8.20-26.72), enquanto a de citações por ano por artigo foi de 4.05 (IC95% = 2.50-5.61). O IF médio por revista foi de 5.14 (IC95% = 4.19-6.09). A maioria dos artigos era de pesquisa secundária (57.48%; n= 242/421), dos quais a maioria eram revisões narrativas (71.90%; n= 174/242). Os países de alta renda foram os mais prolíficos (80.05%; n= 337/421 artigos). Não houve publicações de países de baixa ou média renda. Conclusão Embora ainda baixo, o número de publicações mencionando o ENLS vem aumentando recentemente. A maioria dos artigos foram publicados em revistas de medicina intensiva, neurologia, neurocirurgia e medicina de emergência. Artigos de pesquisa secundária foram os mais comuns, com revisões narrativas sendo o subtipo mais frequente.

Patients' preferences regarding physicians' gender: a clinical center cross-sectional study

ABSTRACT BACKGROUND: Even with the significant growth of female representation within medicine, inequality and prejudice against this group persist. OBJECTIVE: To analyze patients' preferences regarding the gender of physicians in general and according to different specialties, and the possible reasons behind their choice. DESIGN AND SETTING: Cross-sectional study at the Clinical Center of the University of Caxias do Sul, Brazil. METHODS: Over a three-month period in 2020, 1,016 patients were asked to complete a paper-based 11-item questionnaire. RESULTS: The majority (81.7%; n = 830) of the patients did not have a preference regarding the gender of physicians in general. The preference rate for same-gender physicians was 14.0% (n = 142/1,016), and this preference was more common among female than among male patients (17.6% versus 7.0%; odds ratio, OR = 2.85; 95% confidence interval, CI = 1.80-4.52; P < 0.001). When asked about their preference for the gender of the specialist who they were waiting to see, the overall preference rate for a same-gender professional was 17.2% (n = 175). Preference for same-gender specialists was higher for specialties essentially based on pelvic or breast examination (i.e. gynecology, urology, proctology and mastology), compared with others (33.4% versus 9.7%; OR = 4.69; 95% CI = 3.33-6.61; P < 0.001). CONCLUSIONS: The patients' model for choice of their physician does not seem to involve physicians' gender in general or in the majority of medical specialties. The data presented in this study may make it easier to understand patients' preferences and concerns.

Seizures and Epilepsy following Subarachnoid Hemorrhage: A Review on Incidence, Risk Factors, Outcome and Treatment

The mortality rates of subarachnoid hemorrhage (SAH) average 51%, and survivors frequently experience acute and long-term neurological conditions, including seizures and epilepsy. The incidence of post SAH-related seizures and epilepsy, its risk factors, outcomes and management are controversial. The present paper aims to discuss these aspects, to provide the pros and cons of different management options of this condition. A review on PubMed was performed encompassing the incidence of seizures and epilepsy following SAH, the risk factors for its occurrence, its related outcomes, and treatment. The incidence of seizures and epilepsy following SAH varies widely in the literature (from 6 to 26%). Some possible risk factors were identified, such as middle cerebral artery (MCA) aneurysm, Hunt and Hess grade III, aneurysm clipping, thick subarachnoid clot, intracerebral hemorrhage, rebleeding, ischemic brain infarction, Fisher grade III or IV, acute hydrocephalus, hypertension history and poorWorld Federation of Neurosurgical Societies (WFNS) grade. Nevertheless, these relations are frequently uncertain. Also, it appears that the outcome of patients who suffered SAH is worsened by seizures. Given these uncertainties, the need for antiepileptic drug (AED) prophylaxis, the choice of the best drug and dose, as well as the duration of the treatment are controversial topics. However, some recommendations based on low quality evidence are reasonable to be adopted. These include considering AED prophylaxis when a seizure occur after SAH, considering routine long-term AED prophylaxis in specific populations, considering electroencephalogram (EEG) monitoring, and avoiding phenytoin prescription. That is, an individualized approach appears to be the best option, since there is no high-quality evidence.
