OBJECTIVES: To investigate the risk factors and prognosis of hypotension within 72 hours after birth in extremely preterm infants. METHODS: A retrospective analysis was conducted on clinical data of extremely preterm infants admitted to the Children's Hospital of Zhejiang University School of Medicine from January 2019 to April 2022. Based on the presence of hypotension within 72 hours after birth, the eligible infants were divided into a hypotension group (41 cases) and a normotension group (82 cases). The clinical characteristics, echocardiographic parameters within 72 hours after birth, and early complications were compared between the two groups. Multivariate logistic regression analysis was used to explore the risk factors for hypotension within 72 hours after birth, and receiver operating characteristic curve analysis was performed to evaluate the predictive value of relevant indicators for the occurrence of hypotension within 72 hours after birth in the preterm infants. RESULTS: The proportion of infants who required medication or surgical closure of patent ductus arteriosus (PDA), the proportions of infants with intraventricular hemorrhage ≥ grade III and severe pulmonary hemorrhage, and the mortality rate within 7 days in the hypotension group were significantly higher than those in the normotension group (P<0.05). Multivariate logistic regression analysis showed that lower birth weight, larger PDA diameter, and hemodynamically significant PDA were risk factors for the occurrence of hypotension within 72 hours after birth in extremely preterm infants (P<0.05). The receiver operating characteristic curve analysis showed that the combination of birth weight, PDA diameter, and hemodynamically significant PDA had an area under the curve of 0.873 (95%CI: 0.802-0.944, P<0.05) for predicting hypotension within 72 hours after birth, with a sensitivity of 73.2% and specificity of 91.5%. CONCLUSIONS Hypotension within 72 hours after birth is closely related to birth weight and PDA, and increases the risk of early severe complications and mortality in extremely preterm infants.

OBJECTIVES: To investigate the influence of early-stage hypotension defined as mean arterial pressure (MAP)METHODS: A total of 320 preterm infants who were admitted to Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology from April 2020 to August 2021 and met the inclusion criteria were enrolled in this prospective study. Blood pressure within 72 hours was monitored. The definition of hypotension and grouping were as follows: (1) Of the 320 preterm infants, those with MAPn=104), and the others (n=216) served as the control group; (2) Of the 320 preterm infants, those with MAP<30 mmHg in 2 consecutive measurements served as the hypotension group (n=114), and the others served as the control group (n=206). Perinatal data and clinical data during hospitalization were collected.Poor short-term prognosis was defined as death during hospitalization and/or grade Ⅲ-Ⅳ periventricular-intraventricular hemorrhage identified within 1 week after birth. The multivariate logistic regression analysis was used to investigate the influence of hypotension based on the above two definitions on the short-term prognosis of preterm infants. RESULTS: Compared with the control group, the hypotension group based on the above two definitions had higher incidence rates of the clinical manifestations of hypoperfusion, poor prognosis, hemodynamically significant patent ductus arteriosus, and pulmonary hemorrhage (P<0.05). In addition, compared with the control group, the hypotension group defined by MAP<30 mmHg had higher incidence rates of periventricular-intraventricular hemorrhage and bronchopulmonary dysplasia and mortality rate during hospitalization (P<0.05). The incidence of poor short-term prognosis in the hypotension group defined by MAP<30 mmHg was higher than that in the hypotension group defined by MAPP>0.05).The univariate analysis showed that the poor short-term prognosis was related to birth of cesarean section, gestational age, an Apgar score of ≤ 5 at 5 minutes, use of vasoactive drugs within 72 hours, mechanical ventilation within 72 hours, and hypotension under the two definitions (P<0.05).The multivariate logistic regression showed that hypotension based on either definition was not an independent risk factor for poor prognosis (P>0.05). CONCLUSIONS Hypotension based on either definition is not an independent risk factor for short-term poor prognosis in preterm infants with a gestational age of <32 weeks. Hypotension defined by MAP<30 mmHg might be more sensitive than that defined by MAP Infant ; Child ; Infant, Newborn ; Humans ; Pregnancy ; Female ; Gestational Age ; Infant, Premature ; Prospective Studies ; Cesarean Section ; Hypotension/etiology* ; Prognosis ; Cerebral Hemorrhage

In recent years, in the absence of venous component, dilated, overlapping, and tortuous arteries forming a mass of arterial loops with a coil-like appearance have been defined as pure arterial malformation (PAM). It is extremely rare, and its etiology and treatment have not yet been fully elucidated. Here, we reported 2 cases of PAM with associated aneurysmal subarachnoid hemorrhage in this paper. Both patients had severe headache as the first symptom. Subarachnoid hemorrhage was found by CT and computed tomography angiography (CTA) and PAM with associated aneurysm was found by digital subtraction angiography (DSA). In view of the distribution of blood and the location of aneurysms, the aneurysm rupture was the most likely to be considered. Based on the involvement of the lesion in the distal blood supply, only the aneurysm was clamped during the operation. It used to be consider that PAM is safety, because of the presentation and natural history of previously reported cases. Through the cases we reported, we have doubted about "the benign natural history" and discussed its treatment. PAM can promote the formation of aneurysms and should be reviewed regularly. The surgical indications for PAM patients with aneurysm formation need to be further clarified. Management of PAM patients with ruptured aneurysm is the same as that of ruptured aneurysm. Whether there are indications needed to treat simple arterial malformations remains to be further elucidated with the multicenter, randomized controlled studies on this disease.

To determine the etiologies and risk factors of intracerebral hemorrhage in young people.
 Methods: A total of 401 young patients with intracerebral hemorrhage were enrolled, and they were assigned into a 20-29 , a 30-39, and a 40-45 age group. The differences of various etiologies and risk factors among the three groups were analyzed.
 Results: There were 273 men and 128 women in the 401 young patients. The etiologies of 294 patients (73.32%) were identified while 107 patients (26.68%) were unknown. Among those with identified etiology, 226 patients (56.36%) suffered from hypertension, 41 patients (10.22%) congenital cerebrovascular malformation (including 25 patients with cerebral arteriovenous malformation, 8 intracranial cavernous hemangioma, and 8 intracranial aneurysm), and 27 other etiologies (including 9 patients with moyamoya disease, 6 cerebral venous sinus thrombosis, 4 drug abuse, 3 hemorrhagic brain tumor, 2 intracranial infection, 1 systemic lupus erythematosus, 1 drug-induced, and 1 eclampsia). Risk factors included hypertension (237 cases, 59.10%), smoking (123 cases, 30.67%), alcohol consumption (74 cases, 18.45%), and others (19 cases, 4.74%; including 8 cases of pregnancy or in the puerperium, 8 family history of intracerebral hemorrhage, and 3 taking anti-platelet aggregation/anticoagulation agents). The rate of hypertension induced hemorrhage significantly increased with age (P<0.01); the rate of vascular malformations in 20-29 age group was obviously higher than other groups (P<0.01); the rate of unknown cause in the 40-45 age group was significantly lower than other groups (P<0.01) and the rate of other etiologies showed no significant difference in the 3 groups. The rate of hypertension was significantly elevated with the age (P<0.01), while smoking, alcohol consumption, and other risk factors showed no significant difference in the 3 groups.
 Conclusion: The rate of intracerebral hemorrhage in young people increases with the increasing of age and hemorrhage affects men more than women; hypertension may be the main cause and congenital cerebrovascular malformation is the second cause, which may be more common in younger patients. Hypertension, smoking, and alcohol consumption may be the major controllable risk factors in intracerebral hemorrhage in young people.

Progressive hemorrhagic injury (PHI) can be divided into coagulopathy-related PHI and normal coagu- lation PHI. Coagulation disorders after traumatic brain injuries can be included in trauma-induced coagulopathy (TIC). Some studies showed that TIC is associated with PHI and increases the rates of disability and mortality. In this review, we discussed some mechanisms in TIC, which is of great importance in the development of PHI, including tissue factor (TF) hypothesis, protein C pathway and thrombocytopenia. The main mechanism in the relation of TIC to PHI is hypocoagulability. We also reviewed some coagulopathy parameters and proposed some possible risk factors, predictors and therapies.

OBJECTIVETo investigate the effect of advanced maternal age on birth defects and postnatal complications of neonates.

METHODSAmong the 1 109 neonates who were born at The First People's Hospital of Yunnan Province between January 2014 and December 2015, 536 neonates whose mothers were aged ≥35 years were enrolled as advanced age group and 573 neonates whose mothers were aged <35 years were enrolled as appropriate-age group. The incidences of the comorbidities in pregnancy, fetal intrauterine distress, neonatal birth defects, and postnatal complications were compared between the two groups. A univariate logistic regression analysis was performed to analyze the effect of advanced maternal age on neonatal comorbidities during perinatal period.

RESULTSCompared with the appropriate-age group, the advanced age group had significantly higher rate of caesarean section and incidence rates of multiple birth, gestational diabetes, pregnancy-induced hypertension, in vitro fertilization, and fetal intrauterine distress (P<0.01). The neonates in the advanced age group had a significantly higher incidence rate of cleft lip and palate and a significantly lower rate of skeletal dysplasia than in the appropriate-age group (P<0.05). Advanced maternal age was the risk factor for fetal intrauterine distress (OR=2.27, 95%CI: 1.33-3.88, P=0.003), neonatal resuscitation (OR=1.66, 95%CI: 1.19-2.31, P=0.003), and intracranial hemorrhage (OR=2.70, 95%CI: 1.21-6.04, P=0.02).

CONCLUSIONSThe women of maternal advanced age have higher incidence rates of pregnancy comorbidities than those of appropriate age, and the neonates born to the mothers of advanced maternal age have a higher incidence rate of cleft lip and palate. Advanced maternal age may increase the risks of fetal intrauterine distress, neonatal resuscitation, and intracranial hemorrhage.

OBJECTIVETo investigate the result of surgical treatment of active infective endocarditis in patients with recent cerebrovascular events, and to evaluate the optimal indication and timing of surgical intervention.

METHODSThe clinical data of 26 patients with cerebrovascular complications before surgery Between December 2007 and December 2013 were analyzed retrospectively. There were 17 male and 9 female patients, aged (42±14) years. Types of disease included single aortic valvular disease (n=8), single mitral valvular disease (n=12), multiple valvular disease (n=5), and aortic valvular disease with ventricular septal defect (n=1). Type of cerebrovascular complication included cerebral infarction (n=25) and cerebral hemorrhage (n=1). Thirty-one valves were involved in 26 patients, mechanical prosthetic valve replacement (n=25), bioprosthetic valve replacement (n=4), and mitral valve repair (n=2).

RESULTSThe interval between onset of cerebrovascular event and surgical intervention was less than 14 days (n=3), 14 to 21 days (n=13), over 21 days (n=10), and the mean was (20±4) days. There were 33 vegetations found intraoperatively. The mean size of vegetations was (10±4) mm and 19 were found in mitral valve. Two patients died in hospital. One case relapsed after 1 year and underwent reoperation for prosthetic valve endocarditis. The remaining patients recovered with cardiac function of New York Heart Association class I to II after the period of 3 months to 5 years follow-up.

CONCLUSIONSAppropriate surgery may effectively improve the outcome of IE patients with cerebrovascular complications. The surgical indications and risks of further neurologic deterioration after cardiac surgery should be assessed comprehensively before surgical intervention.
