Objective:To explore the clinical characteristics of neonatal ureaplasma meningitis.Methods:A retrospective analysis was conducted on the clinical manifestations, diagnosis, treatment, and follow-up of a case of ureaplasma parvum (UP) meningitis in a neonate with persistent cerebrospinal fluid (CSF) abnormalities, admitted to the Neonatology Department of the Children's Hospital of Chongqing Medical University on September 2021. Literature was searched using the keywords "neonate", "ureaplasma", and "meningitis" in databases including CNKI, Wanfang Medical Database, Yiigle, VIP Database, SinoMed, and Chinese Medical Care Repository, as well as PubMed, Embase, and Web of Science, from their inception to December 2023. The clinical characteristics of the cases obtained were analyzed in conjunction with the present case. Descriptive statistical analysis and Chi-square test (or Fisher's exact test) were used for data analysis. Results:(1) Case report: The patient was a female neonate, born at 30 +2 gestational weeks, who experienced severe asphyxia at birth and was transferred to the neonatal intensive care unit of our hospital after resuscitation involving mechanical ventilation and chest compressions at an external hospital. On the 7th day of birth, the patient developed seizures, and CSF examination indicated meningitis. Blood and CSF cultures were negative, and empirical anti-infective treatment for one month showed no significant improvement. On the 39th day of birth, metagenomics next generation sequencing (mNGS) of the CSF indicated UP positivity, confirming UP meningitis. The patient received ten weeks of quinolone antibiotics. During hospitalization, a ventriculoperitoneal shunt was performed due to hydrocephalus, and the patient was discharged after improvement. At 2 years and 1 month of follow-up, the patient had cerebral palsy (hemiplegic type) and was undergoing rehabilitation therapy. (2) Literature review: A total of 31 articles were retrieved, encompassing 46 cases, plus the present case, making a total of 47 cases. Among these, 57% (27/47) were preterm infants, 54% (22/41) were low birth weight infants (some articles did not report this item, hence the denominator is less than 47), and 76% (28/37) were born via vaginal delivery. Cases who developed symptoms within the first week accounted for 71% (24/34), and 74% (26/35) had mothers with ureaplasma infection or high-risk factors during pregnancy. The main clinical manifestations included fever [63% (20/32)], seizures or apnea/respiratory distress [each 44% (14/32)]. CSF examination mainly showed significantly elevated white blood cells [287×10 6/L (69×10 6/L-1 176×10 6/L)], decreased glucose [0.79 mmol/L (0.10-1.17 mmol/L)], and elevated protein [3.01 g/L (1.80-8.14 g/L)], with negative general bacterial cultures. CSF mNGS [30% (14/47)], CSF polymerase chain reaction [17% (8/47)], and CSF culture [66% (31/47)] were the main methods for detecting ureaplasma. Treatment primarily involved macrolide antibiotics alone [46% (16/35)] or in combination with other antibiotics [29% (10/35)]. The duration of anti-ureaplasma treatment ranged from 2 to 10 weeks. Intracranial hemorrhage and hydrocephalus were the most common neurological complications [66% (25/38) and 61% (23/38), respectively]. Among the 47 cases, 31 were infected with ureaplasma urealyticum (UU) and 15 with UP (one case was not typed). There were no significant differences in epidemiology, clinical manifestations, neurological complications, and prognosis between UP and UU meningitis. Compared to UU meningitis, a higher proportion of UP meningitis cases were treated with macrolide antibiotics [13/15 vs. 52% (14/27), χ2=5.09, P=0.024]. Among the 43 reported cases of ureaplasma meningitis with outcomes, 44% (19/43) experienced developmental delays or death. The case fatality rate of UU meningitis was higher than that of UP meningitis [39% (11/28) vs. 0/14, Fisher's exact test, P=0.007]. Conclusions:Neonatal ureaplasma meningitis lacks specific clinical manifestations and has a variable prognosis. When empirical anti-infective treatment is ineffective in infants with purulent changes in CSF, intracranial ureaplasma infection should be considered. Macrolide antibiotics alone or in combination with other antibiotics can be the first-choice treatment for ureaplasma infection.

Objective     To investigate the effect and prognosis of patients with ventricular septal rupture after myocardial infarction treated by surgical repair combining an occluder and a patch. Methods     Clinical data of 42 patients with myocardial infarction complicated with ventricular septal rupture admitted to the First Affiliated Hospital of Zhengzhou University from January 2010 to September 2021 were retrospectively analyzed. According to the surgical methods, 27 patients were divided into a traditional group, including 17 males and 10 females, with an average age of 62.81±6.81 years, who were repaired by patch only, and 15 patients were divided into a modified group, including 11 males and 4 females, with an average age of 64.27±9.24 years, who were repaired by surgery combining an occluder and a patch. Perioperative and follow-up data of the two groups were compared and analyzed. Results     There were statistical differences between the two groups in preoperative Killip grading, rate of intra-aortic balloon pump use, interval from myocardial infarction to operation, and the number of culprit artery (P<0.05). There was no statistical difference in other preoperative data, the cardiopulmonary bypass time, aortic cross-clamping time, postoperative hospital stay or in-hospital death rate between the two groups (P>0.05). No residual shunt occurred in the modified group, and the difference was statistically significant compared with the traditional group (P=0.038). There was no statistical difference in other complications between the two groups (P>0.05). The median follow-up time was 4 years. Two patients in the traditional group and one in the modified group died during follow-up. The follow-up cardiac function grading of patients in the modified group was statistically different from that in the traditional group (P=0.023). Conclusion     The perioperative  mortality of ventricular septal rupture after myocardial infarction is high, but the long-term effect is satisfactory. Surgical repair combining an occluder and a patch is a safe and effective treatment for ventricular septal rupture, which can effectively reduce postoperative residual shunt.
