Value of short-time transcutaneous carbon dioxide and oxygen pressure monitoring in critically ill preterm infants / 中华围产医学杂志

Objective:To investigate the value of short-time transcutaneous carbon dioxide pressure (TcPCO 2) and transcutaneous oxygen pressure (TcPO 2) monitoring in critically ill preterm infants. Methods:From January to December 2018, 62 critically ill neonates receiving respiratory support at Guangzhou Women and Children's Medical Center were retrospectively enrolled. A total of 348 sets of paired data including TcPCO 2/TcPO 2 and arterial carbon dioxide pressure (PaCO 2)/arterial oxygen partial pressure (PaO 2) were analyzed. The patients were divided into different groups based upon birth weight (23 cases>1 000 g-≤1 500 g, 129 sets of paired data; 18 cases≤1 000 g, 130 sets of paired data) and gestational age (16 cases born at ≤28 gestational weeks, 127 sets of paired data; 29 cases born at 28-34 gestational weeks, 159 sets of paired data) and the differences between groups were compared. The correlation and consistency of TcPCO 2/TcPO 2 and PaCO 2/PaO 2 were evaluated using Pearson's correlation and Blan-Altman scatter plots. Receiver operating characteristic (ROC) curve was drawn to analyze the diagnostic efficacy of TcPCO 2 in neonates with hypercapnia. Results:There was a positive correlation between TcPCO 2 and PaCO 2 in all patients ( r=0.913, 95% CI:0.894-0.929, P<0.05). In patients whose birth weight was>1 000 g-≤1 500 g or≤1 000 g, TcPCO 2 and PaCO 2 were positively correlated and the consistency were good ( r=0.909, 95% CI:0.874-0.935; r=0.934, 95% CI:0.908-0.953; both P<0.05), and the same finding was also observed in patients born at≤28 gestational weeks or 28-34 weeks of gestation ( r=0.938, 95% CI:0.913-0.956; r=0.871, 95% CI: 0.827-0.904; both P<0.05). The sensitivity, specificity and area under curve of TcPCO 2 in the diagnosis of hypercapnia were 90.91%, 85.85%, and 0.942, respectively. There was a poor correlation between TcPO 2 and PaO 2 in all patients and those with birth weight >1 000 g-≤1 500 g or gestational age 28-34 weeks (all r<0.75, all P<0.05). There was no correlation between TcPO 2 and PaO 2 in the birth weight ≤1 000 g and gestational age ≤28 weeks groups (both P>0.05). Conclusions:Short-time TcPCO 2 monitoring can accurately assess PaCO 2 in critically ill neonates requiring respiratory support and is of high diagnostic value for hypercapnia. However, TcPO 2 has limitation in evaluating PaO 2 and other indicators may need to be involved.

Neonatal transaldolase deficiency: a case report / 中华围产医学杂志

We report a neonate with transaldolase deficiency caused by compound heterozygous variation of the TALDO1 gene. A pregnant woman, who had an adverse pregnancy history, was found with multiple fetal abnormalities on prenatal ultrasound and the following whole exon sequencing indicated a likely pathogenic heterozygous variation of c.462-2A>G and c.574C>T(p.R192C) in TALDO1 gene in the fetus. A body was born at 38 +1 weeks and presented dysmorphic features (cutis laxa/wrinkled skin and low-set ears, etc.), splenomegaly, anemia, abnormal liver function and coagulation. In combination with the prenatal testing results, transaldolase deficiency was diagnosed. The patients still had cutis laxa/wrinkled skin on the back of both hands and neck at one year and three months old. Therefore, for babies with hepatosplenomegaly, anemia, thrombocytopenia, coagulation dysfunction, at the same time with dysmorphic features such as cutis laxa, low-set ears, attention should be paid to the investigation of transaldolase deficiency.

Practice and service models of adolescent outpatient clinic / 中国学校卫生

Objective@#Practice of setting up campus clinics in school,to explore adolescent outpatient service mode to better meet the diversified demands of teenagers,and to promote more effective implementation of adolescent health care.@*Methods@#Campus-based adolescent outpatient clinics were established in 2 universities in Chongqing,a questionnaire survey was conducted among 136 students who participated in the consultation, campus-based outpatient services and adolescents’ satisfaction towards the services were analyzed. Hospital adolescent outpatient services were compared before and after the establishment of campus adolescent clinic.@*Results@#Most of adolescent outpatient clinic in hospitals offered disease-based treatment instead of consultation. The overall satisfaction rate was 94.85%, and the satisfaction towards service ability, communication skills, outpatient time arrangement, and privacy protection was 96.32%, 96.32%, 88.97% and 94.12%, respectively. After the establishment of campus adolescent outpatient clinics, adolescent outpatient services in hospital increased dramatically including consultation.@*Conclusion@#It is necessary to offer adolescent outpatient services in schools, which are more helpful for the diversified demands of teenagers.
