RESUMO
INTRODUCTION: Fuziline is one of the many antioxidants currently being tested to treat cardiac damage. In our study, histopathological and biochemical effects of fuziline were investigated in mice with dobutamine-induced heart damage in vitro. METHODS: Thirty-two adult male BALB/c mice, average weight of 18-20 g, were randomly divided into four groups - Group 1 (sham, n=8), Group 2 (control, dobutamine, n=8), Group 3 (treatment 1, dobutamine + fuziline, n=8), and Group 4 (treatment 2, fuziline, n=8). Biochemical parameters and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values were measured. Interleukin 1 beta (IL-1ß), NLR family, pyrin domain containing protein 3 (NLRP3), 8-hydroxy-deoxyguanosine (8-OHDG), gasdermin D (GSDMD), and galectin 3 (GAL-3) levels were analyzed by enzyme-linked immunosorbent assay method, and histopathological examination of heart tissues was performed. RESULTS: When dobutamine + fuziline and fuziline groups were compared, troponin-I (P<0.05), NLRP3 (P<0.001), GSDMD (P<0.001), 8-OHDG (P<0.001), IL-1ß (P<0.001), and GAL-3 (P<0.05) were found to be statistically significant. TOS level was the highest in the dobutamine group (P<0.001) and TAS level was the highest in the fuziline group (P<0.001). OSI level was statistically significant between the groups (P<0.001). In histopathological examination, focal necrosis areas were smaller in the dobutamine + fuziline group than in the dobutamine group, and cardiac myocytes were better preserved. CONCLUSION: Fuziline markedly reduced cardiac damage and pyroptosis in mice with dobutamine-induced heart damage by lowering the levels of GSDMD, 8-OHDG, IL-1ß, and GAL-3. It also prevented necrosis of cardiac myocytes in histopathological evaluation.

Biochemical parameters and total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) values were measured. Interleukin 1 beta (IL-1β), NLR family, pyrin domain containing protein 3 (NLRP3), 8-hydroxy-deoxyguanosine (8-OHDG), gasdermin D (GSDMD), and galectin 3 (GAL-3) levels were analyzed by enzyme-linked immunosorbent assay method, and histopathological examination of heart tissues was performed.

RESUMO
OBJECTIVE: To compare the outcomes of emergency and planned peripartum hysterectomies. METHODS: The present retrospective cross-sectional study was conducted in two hospitals. Maternal and neonatal outcomes were compared according to emergency and planned peripartum hysterectomies. RESULTS: A total of 34,020 deliveries were evaluated retrospectively, and 66 cases of peripartum hysterectomy were analyzed. Of these, 31 were cases of planned surgery, and 35 were cases of emergency surgery. The patients who underwent planned peripartum hysterectomy had a lower rate of blood transfusion (83.9% versus 100%; p = 0.014), and higher postoperative hemoglobin levels (9.9 ± 1.3 versus 8.3 ± 1.3; p < 0.001) compared with the emergency hysterectomy group. The birth weight was lower, although the appearance, pulse, grimace, activity, and respiration (Apgar) scores were higher in the planned surgery group compared with the emergency cases. CONCLUSION: Planned peripartum hysterectomy with an experienced team results in less need for transfusion and improved neonatal outcomes compared with emergency peripartum hysterectomy.
OBJETIVO: Comparar os resultados das histerectomias periparto de emergência e planejada. MéTODOS: Este estudo transversal retrospectivo foi realizado em dois hospitais. Os resultados maternos e neonatais foram comparados de acordo com as histerectomias periparto de emergência e planejada. RESULTADOS: Um total de 34.020 partos foram avaliados retrospectivamente, e 66 casos de histerectomia periparto foram analisados. Destes, 31 eram casos de cirurgias planejadas, e 35, cirurgias de emergência. As pacientes que foram submetidas à histerectomia periparto planejada tiveram uma taxa menor de transfusão de sangue (83,9% versus 100%; p = 0,014), e níveis mais elevados de hemoglobina pós-operatória (9,9 ± 1,3 versus 8,3 ± 1,3; p < 0,001) em comparação com o grupo de histerectomia de emergência. O peso ao nascer foi menor, embora as pontuações na escala de aparência, frequência cardíaca, irritabilidade reflexa, tônus muscular, e respiração (appearance, pulse, grimace, activity, and respiration, Apgar, em inglês) fossem maiores no grupo da cirurgia planejada em comparação com os casos de emergência. CONCLUSãO: A histerectomia periparto planejada com uma equipe experiente resulta em menos necessidade de transfusão e melhora os resultados neonatais em relação à histerectomia periparto de emergência.
