RESUMO
Objective To evaluate the relationship between sleep and sleepiness with memory complaints. Materials and Methods Patients who were submitted to polysomnography between May and September of 2022 and answered the prospective and retrospective memory questionnaire and the Epworth sleepiness scale were included, respectively. Data were entered into an Excel spreadsheet and converted to a file compatible with the SPSS software. Results The sample consisted of 98 subjects, 62.2% male, mean age of 45.9 years, 73.4% overweight, 54.1% with comorbidities, and 51% with excessive sleepiness. There was a significant difference in sleep efficiency, respiratory disturbance index (RDI), slow wave sleep (SWS), and rapid eye movement (REM) sleep for the group with comorbidities; in latency to sleep and SWS between genders; and in RDI for the body mass index group. No correlation between RDI and memory could be identified, but there were statistically significant correlations between REM and sleep efficiency; RDI and REM sleep; RDI and SWS; SWS and sleep efficiency; and sleep efficiency and latency to sleep onset. Older adults performed better on memory tests when total sleep time (TST) is longer than 5 hours and excessive daytime sleepiness is related to complaints of prospective, retrospective, and total memory. Conclusion Elderly people with TST longer than 5 hours have a better memory. Although a correlation between RDI and memory was not observed, a correlation between excessive daytime sleepiness-one of the main symptoms of patients with sleep disorders-and memory was.
RESUMO
OBJECTIVE: to determine the prevalence and describe the main morphological and metric variations of the splenic artery in terms of its origin, path and polar and terminal branches. METHODS: cross-sectional study, carried out at Hospital de Clínicas between July and November 2020. Computed tomography scans were analyzed with intravenous contrast of the patients seen at the Radiology and Diagnostic Imaging Service. The findings were categorized as to origin, path and splenic ramifications. RESULTS: 1,235 patients were evaluated. As for the origin, the splenic artery appears in the celiac trunk in 99.11% of the individuals. Of these, 5.95% have a bifurcated celiac pattern, 92.17% trifurcated and 1.88% tetrafurcated. The mean arterial diameter was 5.92mm (±1.2), the highest one being in white men. As for the path, the splenic artery was unique in the entire sample. The suprapancreatic course was found in 75.63% of the individuals, with a higher occurrence in women, 78.87% (p<0.001). The terminal splitting pattern of the splenic artery was characterized by the bifurcated type (95.47%). The terminal branches seen most frequently were those with three arteries (34.90%) and most individuals did not have polar branches. CONCLUSION: the splenic artery presents a highly variable pattern of origin and its average caliber is influenced by sex and color. The suprapancreatic path was the most characteristic and predominant in females. The bifurcated pattern of final division, with three terminal branches and the absence of polar arteries, occurs more frequently.

RESUMO Objetivo: determinar a prevalência e descrever as principais variações morfológicas e métricas da artéria esplênica quanto a sua origem, trajeto e ramos terminais e polares. Métodos: estudo transversal, realizado no Hospital de Clínicas entre julho e novembro de 2020. Foram analisadas tomografias computadorizadas com contraste endovenoso dos pacientes atendidos no Serviço de Radiologia e Diagnóstico por Imagem. Os achados foram categorizados quanto à origem, trajeto e ramificações esplênicas. Resultados: foram avaliados 1.235 pacientes. Quanto à origem, a artéria esplênica surge no tronco celíaco em 99,11% dos indivíduos. Desses, 5,95% apresentam padrão celíaco bifurcado, 92,17% trifurcado e 1,88% tetrafurcado. O diâmetro arterial médio foi de 5,92mm (±1,2), sendo a maior média em homens brancos. Quanto ao trajeto, a artéria esplênica se apresentou única em toda a amostra. O curso suprapancreático esteve em 75,63% dos indivíduos, com maior ocorrência em mulheres 78,87% (p<0,001). O padrão de divisão terminal da artéria esplênica caracterizou-se pelo tipo bifurcado (95,47%). Os ramos terminais visualizados mais frequentemente foram os com três artérias (34,90%) e a maioria dos indivíduos não apresentou ramos polares. Conclusão: a artéria esplênica apresenta padrão de origem altamente variável e seu calibre médio é influenciado por sexo e cor. O trajeto suprapancreático foi o mais característico e predominou no sexo feminino. O padrão bifurcado de divisão final, com três ramos terminais e ausência de artérias polares, ocorre com maior frequência.
