Umbral crítico de administración en pacientes con trauma severo y reanimación endovascular: ¿Un concepto útil? / Critical Administration Threshold in severe trauma patients and endovascular resuscitation: A useful concept?

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.

Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

Effects of oxytocin induction on early postpartum hemorrhage, perineal integrity, and breastfeeding: a case-control study

SUMMARY OBJECTIVE: The aim of this study was to evaluate the postpartum hemorrhage, perineal integrity, and breastfeeding results of mothers who underwent oxytocin induction in the first stage of labor in the early postpartum period. METHODS: This single-center observational case-control study was conducted in the obstetric unit of a public hospital in Istanbul. The study sampling included 44 pregnant women who received oxytocin induction (case group) and 44 pregnant women who did not receive oxytocin (control group). The Personal Information Form, LATCH Breastfeeding Assessment Tool, Breastfeeding Self-Efficacy Scale, Redness, Edema, Ecchymosis, Discharge, and Approximation Scale, and Postpartum Hemorrhage Collection Bag were used in data collection, and pad follow-up was carried out. RESULTS: The amount of hemorrhage in the first 24 h of the postpartum period and the mean Redness, Edema, Ecchymosis, Discharge, and Approximation Scale score were significantly higher in the case group. While 47.7% of the oxytocin-induced women had 1st or 2nd, and 11.4% had 3rd or 4th degrees of lacerations, 20.5% of the control group had 1st or 2nd, and 2.3% had 3rd or 4th degrees of lacerations. There was no significant difference between the mean scores of the Breastfeeding Self-Efficacy Scale and LATCH Breastfeeding Assessment Tool in both groups. CONCLUSION: According to the study findings, it was determined that oxytocin induction administered in the first stage of labor increased hemorrhage and perineal trauma in the early postpartum period but did not affect the results of breastfeeding. Clinical Trial Registration Number: NCT04441125.

Compression pre-stapler firing and post-ignition wait during sleeve gastrectomy: a prospective randomized trial

ABSTRACT BACKGROUND: Insufficient research exists on the stapling technique in and duration of laparoscopic sleeve gastrectomy (LSG). OBJECTIVES: This study aimed to assess the clinical outcomes using a 30-second precompression and post-firing waiting time without extra support for the stapling line. DESIGN AND SETTINGS: Randomized controlled prospective study at a university hospital. METHODS: This study included 120 patients treated between January 2022 and February 2023. The patients were divided into the non-waiting group (T0) and waiting group (T1), each with 60 patients. Perioperative complications were analyzed using statistical tests. RESULTS: The waiting group (T1) showed a significant reduction in the number of intraoperative bleeding points requiring intervention compared with the non-waiting group (T0) (81 versus 134, P < 0.05). In T0, postoperative C-reactive protein (CRP) levels increased (P < 0.05) and hemoglobin levels decreased significantly (P <0.05). The study recorded 22 postoperative complications, accounting for 18.3% of all cases during the 30-day postoperative period. CONCLUSIONS: The study concluded that the 30 sec + 30 sec stapling technique reduces perioperative bleeding, length of stay, and serious complication rates and is practical and effective for LSG.

Homocysteine serum levels in patients with ruptured and unruptured intracranial aneurysms: a case-control study / Homocisteína sérica em pacientes com aneurismas rotos e não rotos: um estudo caso-controle

Abstract Background There is very few data regarding homocysteine's influence on the formation and rupture of intracranial aneurysms. Objective To compare homocysteine levels between patients with ruptured and unruptured intracranial aneurysms, and to evaluate possible influences of this molecule on vasospasm and functional outcomes. Methods This is a retrospective, case-control study. We evaluated homocysteinemia differences between patients with ruptured and unruptured aneurysms; and the association of homocysteine levels with vasospasm and functional outcomes. Logistic regressions were performed. Results A total of 348 participants were included: 114 (32.8%) with previous aneurysm rupture and 234 (67.2%) with unruptured aneurysms. Median homocysteine was 10.75μmol/L (IQR = 4.59) in patients with ruptured aneurysms and 11.5μmol/L (IQR = 5.84) in patients with unruptured aneurysms. No significant association was detected between homocysteine levels and rupture status (OR = 0.99, 95% CI = 0.96-1.04). Neither mild (>15μmol/L; OR = 1.25, 95% CI 0.32-4.12) nor moderate (>30μmol/L; OR = 1.0, 95% CI = 0.54-1.81) hyperhomocysteinemia demonstrated significant correlations with ruptured aneurysms. Neither univariate (OR = 0.86; 95% CI 0.71-1.0) nor multivariable age-adjusted (OR = 0.91; 95% CI = 0.75-1.05) models evidenced an association between homocysteine levels and vasospasm. Homocysteinemia did not influence excellent functional outcomes at 6 months (mRS≤1) (OR = 1.04; 95% CI = 0.94-1.16). Conclusion There were no differences regarding homocysteinemia between patients with ruptured and unruptured intracranial aneurysms. In patients with ruptured aneurysms, homocysteinemia was not associated with vasospasm or functional outcomes.

Nem a hiperhomocisteinemia leve (>15μmol/L; OR = 1,25, 95% CI = 0,32-4,12) nem a moderada (>30μmol/L; OR = 1,0, 95% CI = 0,54-1,81) mostraram correlações significativas com aneurismas rotos. Modelos univariados (OR = 0,86; 95% CI = 0,71-1,0) e multivariados ajustados por idade (OR = 0,91; 95% CI = 0,75-1,05) não evidenciaram associação entre homocisteína e vasoespasmo. A homocisteinemia não influenciou resultados funcionais excelentes em seis meses (mRS ≤ 1) (OR = 1,04; 95% CI = 0,94-1,16). Conclusão Não houve diferenças em relação à homocisteinemia entre pacientes com aneurismas intracranianos rotos e não rotos. Em pacientes com aneurismas rotos, a homocisteinemia não foi associada ao vasoespasmo ou resultados funcionais.

Autopsy findings of fatal retroperitoneal hemorrhage after traumatic rupture of bilateral renal angiomyolipoma

ABSTRACT The present work reports the autopsy findings of a unique case characterized by fatal retroperitoneal hemorrhage following the traumatic rupture of bilateral renal angiomyolipomas. Renal angiomyolipomas are generally benign tumors with an unpredictable clinical course, ranging from asymptomatic to sudden rupture and hemorrhagic shock. They may be associated with genetic disorders such as tuberous sclerosis complex. The case under investigation is unprecedented in the medical literature due to its bilateral nature and fatal outcome. Autopsy analysis revealed an extensive retroperitoneal hemorrhage originating from bilateral ruptured tumors. Microscopic examination found features consistent with bilateral renal angiomyolipoma. Circumstantial information identified a traffic accident before the death, considering it as the cause of the tumors' traumatic rupture. In this case, due to the severity of the situation, immediate medical measures—such as fluid resuscitation, coagulopathy correction, and surgical treatment, which are usually lifesaving—could not be performed. This led to the patient being declared dead at the scene of the crash.

Early-onset neonatal sepsis as a risk factor for peri-intraventricular hemorrhage in premature infants / Sepse precoce como fator de risco para hemorragia peri-intraventricular em prematuros

ABSTRACT Objective: To assess early-onset sepsis as a risk factor of peri-intraventricular hemorrhage in premature infants born at less than or equal to 34 weeks' gestation and admitted to a neonatal intensive care unit (NICU). Methods: This retrospective cohort study included premature patients born at less than or equal to 34 weeks' gestation who were admitted to the NICU of a tertiary hospital in southern Brazil, and born from January 2017 to July 2021. Data were collected from patients' medical records. Early-onset sepsis was measured according to the presence or absence of diagnosis within the first 72 hours of life, whereas the outcome, peri-intraventricular hemorrhage, was described as the presence or absence of hemorrhage, regardless of its grade. Results: Hazard ratios were calculated using Cox regression models. A total of 487 patients were included in the study, of which 169 (34.7%) had some degree of peri-intraventricular hemorrhage. Early-onset sepsis was present in 41.6% of the cases of peri-intraventricular hemorrhage, which revealed a significant association between these variables, with increased risk of the outcome in the presence of sepsis. In the final multivariate model, the hazard ratio for early-onset sepsis was 1.52 (95% confidence interval 1.01-2.27). Conclusion: Early-onset sepsis and the use of surfactants showed to increase the occurrence of the outcome in premature children born at less than or equal to 34 weeks' gestation. Meanwhile, factors such as antenatal corticosteroids and gestational age closer to 34 weeks' gestations were found to reduce the risk of peri-intraventricular hemorrhage.

RESUMO Objetivo: O objetivo do presente trabalho foi avaliar a sepse precoce como fator de risco para hemorragia peri-intraventricular (HPIV) em prematuros com 34 semanas ou menos, admitidos em Unidade de Terapia Intensiva (UTI) Neonatal. Métodos: Este estudo de coorte retrospectivo incluiu pacientes prematuros com 34 semanas ou menos, que receberam alta da UTI Neonatal de hospital terciário, no sul do Brasil, nascidos no período de janeiro de 2017 a julho de 2021. Os dados foram coletados por meio dos prontuários desses pacientes. A sepse precoce foi mensurada conforme a presença ou a ausência do diagnóstico nas primeiras 72 horas de vida. Já o desfecho, hemorragia peri-intraventricular, foi descrito conforme a presença ou ausência da hemorragia, independentemente do grau. Resultados: Hazard ratios (HR) foram calculados por meio de modelos de regressão de Cox. Foram incluídos no estudo 487 pacientes. Destes, 169 (34,7%) apresentaram algum grau de hemorragia peri-intraventricular. A sepse precoce esteve presente em 41,6% dos casos de hemorragia peri-intraventricular e apresentou associação significativa, elevando o risco do desfecho quando presente. No modelo multivariável final, o HR para a sepse precoce foi de 1,52 (intervalo de confiança de 95% — IC95% 1,01-2,27). Conclusão: Sepse precoce e uso de surfactante demonstraram aumentar a ocorrência do desfecho em crianças prematuras até 34 semanas, enquanto fatores como corticoide antenatal e idades gestacionais mais próximas a 34 semanas mostraram reduzir o risco de ocorrência hemorragia peri-intraventricular.

Efficacy of percutaneous transhepatic variceal embolization alone or in combination with partial splenic embolization in treatment of portal hypertensive hemorrhage in liver cirrhosis： A Meta-analysis / 临床肝胆病杂志

ObjectiveTo investigate the efficacy of percutaneous transhepatic variceal embolization （PTVE） alone or in combination with partial splenic embolization （PSE） in the treatment of portal hypertensive hemorrhage in liver cirrhosis through a meta-analysis. MethodsThis study was conducted according to PRISMA guideline， with a PROSPERO registration number of CRD42023396690. Wanfang Med Online， CNKI， CBM， VIP Databases， PubMed， Embase， the Cochrane Library， and Web of Science databases were searched for articles on PTVE alone or in combination with PSE in the treatment of portal hypertensive hemorrhage in liver cirrhosis published up to December 23， 2022. The articles were selected based on inclusion and exclusion criteria， and related data were extracted. The RevMan 5.4.1 statistical analysis software was used to perform the meta-analysis. ResultsEight articles were finally included， with a total sample size of 592 cases， among which there were 316 cases in the PTVE+PSE group and 276 cases in the PTVE group. The meta-analysis showed that compared with the PTVE group， the PTVE+PSE group had significantly lower postoperative portal vein pressure （standardized mean difference ［SMD］=-1.75， 95% confidence interval ［CI］： -2.33 to -1.16， P<0.05）， postoperative diameter of the portal vein （SMD=-0.87， 95%CI： -1.64 to -0.10， P<0.05）， postoperative rebleeding rate （odds ratio ［OR］=0.17， 95%CI： 0.11 — 0.28， P<0.05）， mortality rate （OR=0.13， 95%CI： 0.04 — 0.37， P<0.05）， and incidence rate of postoperative portal hypertensive gastrointestinal disease （OR=0.17， 95%CI： 0.07 — 0.45， P<0.05］， as well as a significantly higher postoperative platelet level （SMD=0.79， 95%CI： 0.52 — 1.06， P<0.05）， while there were no significant differences between the two groups in the incidence rates of postoperative ascites. ConclusionCompared with PTVE alone， PTVE combined with PSE can effectively reduce the rebleeding rate and mortality rate of portal hypertensive hemorrhage in liver cirrhosis， the incidence rate of portal hypertensive gastrointestinal disease， and portal vein pressure， and it can also shorten the diameter of the portal vein and increase platelet level. Therefore， it is an effective interventional method for the treatment of portal hypertension hemorrhage in liver cirrhosis.

Objective To retrospectively analyze the epidemiological trend of children with lower gastrointestinal bleeding in recent 10 years,and investigate the change of their disease burden,so as to provide a theoretical basis for the accurate prevention and control of children's lower gastrointestinal bleeding. Methods A total of 671 children with "lower gastrointestinal bleeding" who were diagnosed in our hospital from 2012 to 2021 were collected as research subjects. To analyze the microscopic examination rate and common etiology of lower gastrointestinal bleeding in children in the past 10 years,as well as the epidemiological characteristics of different age groups, different regions and different basic diseases; Calculate and compare the rate of disability life lost (YLD), early death life lost (YLL) and disability adjusted life year (DALY) of children with lower gastrointestinal bleeding within 10 years, and calculate the annual change percentage (AAPC) to analyze the change trend of disease burden. Results The microscopic examination rate of children with lower gastrointestinal bleeding showed a trend of increasing in the past 10 years (P18 years old, hypertension and gastroenteritis. The DALY rate, YLL rate and YLD rate caused by lower gastrointestinal bleeding in the past 10 years showed an upward trend (P<0.05). Conclusion The microscopic examination rate of lower gastrointestinal bleeding in children was graduallyincreasing,and the prevalence rate of basic diseases such as boys,hypertension and gastroenteritis was increasing;in addition,the disease burden caused by children's lower gastrointestinal bleeding was also increasing year by year and should be protected.

Efficacy of partial and complete resuscitative endovascular balloon occlusion of the aorta in the hemorrhagic shock model of liver injury / 世界急诊医学杂志（英文）

@#BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) can temporarily control traumatic bleeding. However, its prolonged use potentially leads to ischemia-reperfusion injury (IRI). Partial REBOA (pREBOA) can alleviate ischemic burden; however, its security and effectiveness prior to operative hemorrhage control remains unknown. Hence, we aimed to estimate the efficacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic gun. METHODS: Twenty Landrace pigs were randomized into control (no aortic occlusion) (n=5), intervention with complete REBOA (cREBOA) (n=5), continuous pREBOA (C-pREBOA) (n=5), and sequential pREBOA (S-pREBOA) (n=5) groups. In the cREBOA and C-pREBOA groups, the balloon was inflated for 60 min. The hemodynamic and laboratory values were compared at various observation time points. Tissue samples immediately after animal euthanasia from the myocardium, liver, kidneys, and duodenum were collected for histological assessment using hematoxylin and eosin staining. RESULTS: Compared with the control group, the survival rate of the REBOA groups was prominently improved (all P<0.05). The total volume of blood loss was markedly lower in the cREBOA group (493.14±127.31 mL) compared with other groups (P<0.01). The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups (P<0.05). At 120 min, the S-pREBOA group showed higher alanine aminotransferase (P<0.05) but lower blood urea nitrogen compared with the cREBOA group (P<0.05). CONCLUSION: In this trauma model with liver injury, a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure, despite persistent hemorrhage. Extended tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures, and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.

Research progress in perioperative management of portal vein thrombosis in liver transplantation / 器官移植

Portal vein thrombosis is one of the common complications of liver cirrhosis. The incidence of portal vein thrombosis is increased with the progression of diseases. The incidence and progression of portal vein thrombosis are associated with multiple factors. The indications of anticoagulant therapy remain to be investigated. At present, portal vein thrombosis is no longer considered as a contraindication for liver transplantation. Nevertheless, complicated portal vein thrombosis will increase perioperative risk of liver transplantation. How to restore the blood flow of portal vein system is a challenge for surgical decision-making in clinical practice. Rational preoperative typing, surgical planning and portal vein reconstruction are the keys to ensure favorable long-term prognosis of liver transplant recipients. In this article, epidemiological status, risk factors, typing and identification of portal vein thrombosis, preoperative and intraoperative management of portal vein thrombosis in liver transplantation, and the impact of portal vein thrombosis on the outcomes of liver transplantation were reviewed, aiming to provide reference for perioperative management of portal vein thrombosis throughout liver transplantation.

Correlation between neonatal retinal hemorrhage and changes in umbilical artery blood gas analysis / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the correlation between neonatal retinal hemorrhage(RH)and changes in umbilical artery blood gas analysis.METHODS: A total of 312 full-term neonates born in our obstetrics department from January 2019 to December 2021 were selected as the study subjects. According to the RetCam III fundus examination results, 245 neonates who did not experience RH were included in the control group, while 67 cases with RH were found to be included in the RH group. In addition, neonates were grouped into I degree group(n=20), II degree group(n=29), and III degree group(n=18)based on the degree of RH. General clinical data and umbilical artery blood gas analysis indicators between the RH group and the control group were compared; the levels of umbilical artery blood gas analysis indicators in neonates with different degrees of RH, the relationship between pH and RH degree, and the influencing factors of neonatal RH were analyzed.RESULTS: There was no obvious difference in maternal age, average gestational week, fetal gender, parity, gestational diabetes, fetal birth weight, and amniotic fluid between the RH group and the control group(all P&#x003E;0.05), while there were obvious differences in delivery methods, gestational hypertension, forceps assisted delivery, neonatal asphyxia, and umbilical cord around the neck(all P&#x003C;0.05). The pH value, arterial blood sample partial pressure(PaO2)and base excess(BE)values of the RH group were obviously lower than those of the control group(all P&#x003C;0.01), while the arterial carbon dioxide partial pressure(PaCO2)was obviously higher than that of the control group(P&#x003C;0.01). There were obvious differences in umbilical artery blood gas analysis indicators among children with different degrees of RH(P&#x003C;0.05), and with the increase of the degree of RH, pH value, PaO2 and BE gradually decreased(P&#x003C;0.05), and PaCO2 gradually increased(P&#x003C;0.05). There was a negative correlation between the degree of RH and the pH of umbilical artery blood gas analysis(rs=-0.593, P&#x003C;0.05). The results of multivariate Logistic regression analysis showed that delivery method, gestational hypertension, forceps assisted delivery, neonatal asphyxia, umbilical cord entanglement, pH, PaO2, PaCO2, and BE were all influencing factors for the occurrence of neonatal RH.CONCLUSION: There is a close correlation between neonatal RH and changes in umbilical artery blood gas analysis, and umbilical artery blood gas analysis can be used for the diagnosis of neonatal RH, which can be used to guide clinical treatment.

Establishment of a nomogram model for predicting liver cirrhosis with esophagogastric variceal bleeding based on aspartate aminotransferase-to-platelet ratio index and platelet-albumin-bilirubin score / 临床肝胆病杂志

ObjectiveTo investigate the value of aspartate aminotransferase-to-platelet ratio index （APRI） and platelet-albumin-bilirubin （PALBI） score in predicting the risk of esophagogastric variceal bleeding in patients with liver cirrhosis. MethodsA total of 119 patients with liver cirrhosis who were admitted to The First Affiliated Hospital of Soochow University from May 2021 and June 2022 were enrolled， and clinical data， routine blood test results， serum biochemistry， and coagulation test results were collected from all patients. According to the presence or absence of esophagogastric variceal bleeding， the patients were divided into non-bleeding group with 59 patients and bleeding group with 60 patients， and a comparative analysis was performed for the two groups. The independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-squared test or the Fisher’s exact test was used for comparison of categorical data between groups. The multivariate Logistic regression analysis was used to identify the independent risk factors for esophagogastric variceal bleeding in patients with liver cirrhosis and establish a nomogram predictive model. ResultsThe male patients accounted for 75.00% in the bleeding group and 40.68% in the non-bleeding group， and there was a significant difference in sex composition between the two groups （χ2=14.384， P<0.001）. Chronic hepatitis B was the main etiology in both the bleeding group and the non-bleeding group （53.33% vs 38.98%）， and there was no significant difference in composition ratio between the two groups （χ2=2.464， P=0.116）. Compared with the non-bleeding group， the bleeding group had a significantly higher activity of AT-IIIA （t=3.329， P=0.001） and significantly lower levels of PLT， TBil， Ca， TC， and TT （all P<0.05）. There were significant differences in APRI and PALBI between the two groups （χ2=6.175 and 19.532， both P<0.05）. The binary logistic regression analysis showed that APRI （odds ratio ［OR］=0.309， 95% confidence interval ［CI］： 0.109‍ ‍—‍ ‍0.881， P=0.028）， PALBI （OR=7.667， 95%CI： 2.005‍ ‍—‍ ‍29.327， P=0.003）， Ca （OR=0.001， 95%CI： 0.000‍ ‍—‍ ‍0.141， P=0.007）， TC （OR=0.469， 95%CI： 0.226‍ ‍—‍ ‍0.973， P=0.042）， and TT （OR=0.599， 95%CI： 0.433‍ ‍—‍ ‍0.830， P=0.002） were independent influencing factors for esophagogastric variceal bleeding in liver cirrhosis. A nomogram model was established based on the above factors and had an index of concordance of 0.899 and a well-fitted calibration curve. ConclusionAPRI and PALBI have a good value in predicting esophagogastric variceal bleeding in patients with liver cirrhosis， and the nomogram model established based on this study can predict the incidence rate of esophagogastric variceal bleeding in patients with liver cirrhosis.

Fundus screening results and related factors of fundus diseases in 5 307 newborns / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the results of fundus screening in 5 307 newborns and the related factors of fundus diseases.METHODS: A total of 5 307 newborns who underwent fundus screening in our ophthalmology department from January to December 2022 were selected. RetCam III system was used for fundus examination, and abnormal fundus conditions were recorded. The influencing factors of retinal hemorrhage in full-term infants and retinopathy of prematurity(ROP)in preterm infants were analyzed.RESULTS: The incidence of ocular abnormalities in newborns was 27.17%, with the highest incidence of retinal hemorrhage(61.23%), followed by retinal exudation(22.95%), ROP and ROP like retinopathy(10.68%). The incidence of morning glory syndrome(0.21%), albino fundus(0.21%), and permanent fetal vasculature(PFV; 0.28%)was lower. The incidence of eye abnormalities in full-term infants was lower than that in preterm infants(26.30% vs 30.08%, P&#x003C;0.05), and the incidence of retinal hemorrhage and exudation in full-term infants was higher than that in preterm infants(P&#x003C;0.05). The incidence of ROP and ROP like retinopathy in preterm infants was higher than that in full-term infants(P&#x003C;0.05). Natural delivery is a risk factor for retinal hemorrhage in full-term infants(P&#x003C;0.05). Fetal age(32-34, 30-31 wk), birth weight(1 500-2 499, &#x003C;1 500 g), milk powder feeding, and oxygen inhalation are risk factors for ROP in premature infants(all P&#x003C;0.05).CONCLUSION: The incidence of eye abnormalities in newborns at our hospital is relatively high, and early detection of eye abnormalities in newborns can be achieved through fundus screening.

Findings of ocular examinations in healthy full-term newborns / Achados de exame ocular realizado em recém-nascidos a termo saudáveis

ABSTRACT Purpose: To assess the anterior and posterior segments of full-term neonates over a 1.5-year period. Methods: The findings of full-term neonates who underwent ophthalmological examinations between June 2019 and December 2020 were analyzed, and the results were retrospectively recorded. Results: The study comprised 2972 neonates with a mean birth week of 38.7 ± 1.2 weeks and a mean birth weight of 3235 ± 464 g. The neonates were examined on an average of 49.3 ± 18.9 postnatal days. Of the examined neonates, 185 (6.2%) showed abnormal ophthalmological findings, the most prevalent of which were retinal hemorrhage in 2.3% (n=68) and white changes in the peripheral retina in 1.9% (n=55) of the neonates. Cases of optic disc pathologies (n=20), choroidal nevus (n=10), iris-choroidal coloboma (n=5), subconjunctival hemorrhage (n=6), non-specific retinal pigmentary change (n=4), congenital cataract (n=3), posterior synechia (n=3), iris nevus (n=3), corneal opacity (n=1), choroidal coloboma (n=1), iris coloboma (n=1), buphthalmos (n=1), anophthalmos (n=1), microphthalmia (n=1), lid hemangioma (n=1), and vitreous hemorrhage (n=1) collectively accounted for approximately 2% of all neonates. Pathologies that could potentially impair vision, which were detected by ophthalmological examination, accounted for 1.2% of all neonates (n=37). Conclusion: The most prevalent finding of the ophthalmological examinations of neonates in the present study was retinal hemorrhage. Ophthalmological examinations of neonates can help in identifying diseases that may affect their vision and are curable or may lead to amblyopia in the long term.

Exames oftalmológicos em recém-nascidos podem ser úteis na identificação de doenças que podem impactar a visão deles, podendo ser curáveis ou levar à ambliopia no longo prazo.

Is near-infrared spectroscopy a promising predictor for early intracranial hemorrhage diagnosis in the Emergency Department?

Intracranial hemorrhage (ICH) is a serious medical condition that can lead to significant morbidity and mortality if not diagnosed and treated promptly. Early detection and treatment are essential for improving the outcome in patients with ICH. Near-infrared spectroscopy (NIRS) is a non-invasive imaging technique that has been used to detect changes in brain tissue oxygenation and blood flow in various conditions. The aim of this study was to investigate the predictive potential of NIRS for early diagnosis of ICH in patients presenting to the Emergency Department (ED) triage with headache. A total of 378 patients were included in the study. According to the final diagnosis of the patients, 4 groups were formed: migraine, tension-cluster headache, intracranial hemorrhage and intracranial mass, and control group. Cerebral NIRS values "rSO2" were measured at the first professional medical contact with the patient. The right and left rSO2 (RrSO2, LrSO2) were significantly lower and the rSO2 difference was significantly higher in the intracranial hemorrhage group compared to all other patient groups (P<0.001). The cut-off values determined in the receiver operating characteristics (ROC) analysis were RrSO2 ≤67, LrSO2 ≤67, and ΔrSO2 ≥9. This study found that a difference of more than 9 in cerebral right-left NIRS values can be a non-invasive, easy-to-administer, rapid, and reliable diagnostic test for early detection of intracranial bleeding. NIRS holds promise as an objective method in ED triage for patients with intracranial hemorrhage. However, further research is needed to fully understand the potential benefits and limitations of this method.

Results of office-based fluid-air exchange for postvitrectomy hemorrhage in diabetic retinopathy

ABSTRACT Purpose: This study aimed to evaluate the efficacy and clinical outcomes of a one-way fluid-air exchange procedure for the treatment of postvitrectomy diabetic vitreous hemorrhage in patients with proliferative diabetic retinopathy. Methods: This retrospective study included 233 patients with proliferative diabetic retinopathy, who underwent vitrectomy. A one-way fluid-air exchange procedure was performed in 24 eyes of 24 (10.30%) patients with persistent vitreous cavity rebleeding after the operation. Preprocedural and postprocedural best-corrected visual acuity values were achieved. Complications occurring during and after the procedure were analyzed. Results: Significant visual improvement was observed 1 month after the one-way fluid-air exchange procedure (2.62 ± 0.60 LogMAR at baseline vs. 0.85 ± 0.94 LogMAR at postprocedure, p<0.0001). Moreover, 19 (79.17%) eyes needed the procedure once, and 5 (20.83%) eyed had the procedure more than twice. In 3 (12.50%) eyes, reoperation was eventually required because of persistent rebleeding despite several fluid-air exchanges. No complication was observed during the follow-up. Conclusions: The one-way fluid-air exchange procedure can be an excellent alternative to re-vitrectomy for patients with proliferative diabetic retinopathy suffering from postvitrectomy diabetic vitreous hemorrhage by removing the hemorrhagic contents directly and achieving fast recovery of visual function without apparent complications.

Hemostasis Using Prothrombin Complex Concentrate in Patients Undergoing Cardiac Surgery: Systematic Review with Meta-Analysis

ABSTRACT Objective: The purpose of present study was to comprehensively explore the efficacy and safety of prothrombin complex concentrate (PCC) to treat massive bleeding in patients undergoing cardiac surgery. Methods: PubMed®, Embase, and Cochrane Library databases were searched for studies investigating PCC administration during cardiac surgery published before September 10, 2022. Mean difference (MD) with 95% confidence interval (CI) was applied to analyze continuous data, and dichotomous data were analyzed as risk ratio (RR) with 95% CI. Results: Twelve studies were included in the meta-analysis. Compared with other non-PCC treatment regimens, PCC was not associated with elevated mortality (RR=1.18, 95% CI=0.86-1.60, P=0.30, I2=0%), shorter hospital stay (MD=-2.17 days; 95% CI=-5.62-1.28, P=0.22, I2=91%), reduced total thoracic drainage (MD=-67.94 ml, 95% CI=-239.52-103.65, P=0.44, I2=91%), thromboembolic events (RR=1.10, 95% CI=0.74-1.65, P=0.63, I2=39%), increase in atrial fibrillation events (RR=0.73, 95% CI=0.52-1.05, P=0.24, I2=29%), and myocardial infarction (RR=1.10, 95% CI=0.80-1.51, P=0.57, I2=81%). However, PCC use was associated with reduced intensive care unit length of stay (MD=-0.81 days, 95% CI=-1.48- -0.13, P=0.02, I2=0%), bleeding (MD=-248.67 ml, 95% CI=-465.36- -31.97, P=0.02, I2=84%), and intra-aortic balloon pump/extracorporeal membrane oxygenation (RR=0.65, 95% CI=0.42-0.996, P=0.05, I2=0%) when compared with non-PCC treatment regimens. Conclusion: The use of PCC in cardiac surgery did not correlate with mortality, length of hospital stay, thoracic drainage, atrial fibrillation, myocardial infarction, and thromboembolic events. However, PCC significantly improved postoperative intensive care unit length of stay, bleeding, and intra-aortic balloon pump/ extracorporeal membrane oxygenation outcomes in patients undergoing cardiac surgery.

Avaliação do colírio de brimonidina 0,2% em comparação à nafazolina 0,025% + feniramina 0,3% nas cirurgias de estrabismo / Evaluation of 0.2% brimonidine eye drops compared to 0.025% naphazoline + 0.3% pheniramine in strabismus surgery

RESUMO Objetivo: Avaliar o efeito do colírio de brimonidina 0,2% na redução da hiperemia e do sangramento ocular durante as cirurgias de estrabismo, em comparação com o colírio de nafazolina 0,025% + feniramina 0,3%. Métodos: Foram avaliados 14 pacientes com estrabismo e indicação de correção cirúrgica bilateral. Foi instilado antes do procedimento, de forma aleatória, um colírio em cada olho dos pacientes avaliados. A análise subjetiva da hiperemia conjuntival e do sangramento perioperatório foi realizada de forma duplo-cega, por dois cirurgiões. A avaliação objetiva do nível de hiperemia conjuntival foi realizada por análise das imagens obtidas por meio do software ImageJ®. Resultados: A análise de modelos multivariados de efeito misto indicou diferenças estatisticamente significantes entre os grupos em relação à hiperemia (avaliador 2) e ao sangramento intraoperatório (avaliadores 1 e 2), com maiores escores nos casos tratados com colírio de nafazolina + feniramina. Entretanto, não houve diferença estatística na análise objetiva realizada por meio da saturação de cores obtidas pelo programa ImageJ®. Conclusão: O colírio de brimonidina pode ser superior ao colírio de nafazolina + feniramina na redução do sangramento, levando-se em conta apenas a análise subjetiva.

ABSTRACT Objective: To evaluate the effect of 0.2% brimonidine eye drops in reducing hyperemia and ocular bleeding during strabismus surgeries, in comparison with 0.025% naphazoline + 0.3% pheniramine eye drops. Methods: Fourteen patients with strabismus and indication for bilateral surgical correction were evaluated. Before the procedure, the eye drops were instilled randomly in each eye of the evaluated patients. The subjective analysis of conjunctival hyperemia and perioperative bleeding was performed in a double-blind manner, by 02 surgeons. The objective assessment of the level of conjunctival hyperemia was performed by analyzing the images obtained using the ImageJ® software. Results: The analysis of multivariate mixed effect models indicated statistically significant differences between the groups in relation to hyperemia (rater 2) and intraoperative bleeding (raters 1 and 2) with higher scores in cases treated with naphazoline + pheniramine eye drops. However, there were no statistically significant differences in the objective analysis of color saturation obtained by the ImageJ® program. Conclusion: Brimonidine eye drops may be superior to naphazoline + pheniramine eye drops in reducing bleeding, taking into account the subjective analysis only.

Ocular manifestation of vertical transmission of dengue: case report / Manifestação ocular de transmissão vertical de dengue: relato de caso

ABSTRACT A 7-week-old male delivered by cesarean section presented with a positive serology for dengue along with preretinal and retinal hemorrhages, vitreous opacities and cotton wool spots. The patient and his mother had positive serologies for Non Structural Protein 1 (NS1) by ELISA. Retinal and vitreous findings improved over a sixteen-week period. Spectral domain optical coherence tomography (OCT) showed preserved macular architecture. In this case report, we suggest that retinal and vitreous changes may be the ocular presenting features of vertically transmitted dengue in newborns, and that those findings may resolve with no major structural sequelae.

RESUMO Neonato de 7 semanas, do sexo masculino, nascido de parto cesárea, apresentou sorologia positiva para dengue com hemorragias retinianas e pré-retinianas, opacidades vítreas e manchas algodonosas. O paciente e sua mãe haviam apresentado sorologias positivas para Non Structural Protein 1 através de ELISA. Achados na retina e no vítreo melhoraram em um período de dezesseis semanas. O exame de tomografia de coerência óptica de domínio espectral demonstrou arquitetura macular preservada. Neste relato de caso, sugerimos que alterações na retina e no vítreo podem ser os achados oculares aparentes em neonatos com infecção vertical por dengue, e que estes podem se resolver sem maiores sequelas estruturais.
