RESUMO
AIMS: To synthesise and evaluate the effectiveness of virtual reality interventions in preoperative children. BACKGROUND: Children consider operations as a predictable threat and stressful event. Children's anxiety before an operation increases as the time draws closer. Children could understand the operating room environment and process before the operation using virtual reality, which may reduce their anxiety before an operation. DESIGN: A systematic review and meta-analysis of randomised controlled trials following the Cochrane method were conducted. METHOD: CINAHL, Cochrane Library, Embase, Joanna Briggs Institute, MEDLINE and PubMed databases were searched for randomised controlled trials published before February 2021. A random-effects model meta-analysis to calculate pooled prevalence and 95% confidence intervals was performed. Conduction of the review adheres to the PRISMA checklist. RESULTS: Of 257 articles screened, six interventions involving 529 participants aged 4-12 years were included in the analysis. All study evidence levels were B2/Level 2, the quality was medium to high on the modified Jadad scale, with a low risk of bias. The results revealed that virtual reality significantly reduced preoperative anxiety in children (SMD: -0.91, 95% CI: -1.43 to -0.39, p = .0006). Furthermore, virtual reality significantly improved children's compliance with anaesthesia (SMD: 3.49, 95% CI: 1.32 to 9.21, p = .01). CONCLUSION: Children who used virtual reality before an operation felt more familiar with the operating room environment and understood the preoperative preparation procedures. Virtual reality effectively reduced children's anxiety and improved their compliance with anaesthesia. RELEVANCE TO CLINICAL PRACTICE: This systematic review and meta-analysis investigated the effect of virtual reality on preoperative anxiety in children and the findings supported its positive effects. The results could provide a reference for incorporating virtual reality into preoperative preparation guidelines.

Under the guidance and support of national policies in recent years, the community medical system has been developed rapidly, among which primary child healthcare is carried out routinely in community hospitals, greatly alleviating the pressure of specialized pediatric hospitals and departments of pediatrics in secondary and tertiary general hospitals. However, due to the lack of professional training for primary child healthcare personnel in community medical institutions, early symptoms of children with cerebral palsy cannot be identified and so children with cerebral palsy are often unable to receive early diagnosis and intervention, which may affect their prognosis. An article about international expert consensus and recommendations on early identification and referral of cerebral palsy in community medical institutions was published in Development Medicine and Child Neurology in 2020. It proposed six clinical features that should prompt referral and two warning signs that warrant enhanced monitoring, as well as five recommendations for referral to medical experts and other healthcare professionals for the diagnosis of cerebral palsy. The recommendations may help primary child healthcare personnel in community medical institutions to early identify the children at high risk of cerebral palsy, thus reducing the delay of referral and intervention. This article gives an interpretation of the recommendations based on the actual situation in China, in order to improve the ability of primary child healthcare personnel in community medical institutions to early identify high-risk signals of cerebral palsy and conduct reasonable referral. This will help to achieve the early identification, early diagnosis, and early intervention to improve the prognosis of children with cerebral palsy.

OBJECTIVE: To investigate the infection factors associated with neurodysplasia in early and moderately preterm infants at a corrected age of 18 months. METHODS: The preterm infants with a gestational age of 28 weeks to <34 weeks who were admitted to the neonatal intensive care unit and followed up at the outpatient service for high-risk preterm infants from June 2015 to December 2018 were enrolled as subjects. At a corrected age of 18 months, the revised Bayley Scales of Infant Development was used to evaluate neurodevelopment. Univariate and multivariate logistic regression analyses were used to investigate the infection factors affecting neurodevelopment. RESULTS: A total of 138 early or moderately preterm infants were enrolled, among whom 59 had neurodysplasia at a corrected age of 18 months. The univariate logistic regression analysis showed that neurodysplasia was associated with late-onset infection, positive blood culture, and other systemic infections (P<0.05). The multivariate logistic regression analysis showed that late-onset infection was an independent risk factor for neurodysplasia (OR=1.510, 95%CI: 1.133-3.600, P<0.05). CONCLUSIONS: Late-onset infection can increase the risk of neurodysplasia in early and moderately preterm infants.

OBJECTIVE: To investigate the differences between the Test of Infant Motor Performance (TIMP) data from the infants at 38-58 weeks of postconceptual age in three hospitals in Chongqing, China and the America norms, and to provide a reference for the introduction and application of TIMP in China. METHODS: TIMP was used to assess 642 infants with 38-58 weeks of postconceptual age who visited the departments of preterm infants or child healthcare in the Second Affiliated Hospital of Army Medical University, Shapingba Maternal and Child Health Hospital in Chongqing, and Chongqing Maternal and Child Health Hospital between January and December, 2016. The assessment scores were analyzed and compared with the America norms. RESULTS: The TIMP scores increased with the increasing postconceptual age, with 37±5 points in the 38-39+6 week group and 83±12 points in the 56-57+6 week group. All age groups had a significantly lower mean score than the America norms (P<0.001). CONCLUSIONS: TIMP scores can reflect the motor performance in infants with various postconceptual ages. The TIMP scores from the infants with a postconceptual age of 38-58 weeks in three hospitals in Chongqing are significantly different from the America norms, suggesting that it is very necessary in China to establish the Chinese norms for assessing motor performance in infants using TIMP.

OBJECTIVE: This study was aimed to investigate the toxic effects of 3 nanomaterials, i.e. multi-walled carbon nanotubes (MWCNTs), graphene oxide (GO), and reduced graphene oxide (RGO), on zebrafish embryos. METHODS: The 2-h post-fertilization (hpf) zebrafish embryos were exposed to MWCNTs, GO, and RGO at different concentrations (1, 5, 10, 50, 100 mg/L) for 96 h. Afterwards, the effects of the 3 nanomateria on spontaneous movement, heart rate, hatching rate, length of larvae, mortality, and malformations ls were evaluated. RESULTS: Statistical analysis indicated that RGO significantly inhibited the hatching of zebrafish embryos. Furthermore, RGO and MWCNTs decreased the length of the hatched larvae at 96 hpf. No obvious morphological malformation or mortality was observed in the zebrafish embryos after exposure to the three nanomaterials. CONCLUSION: MWCNTs, GO, and RGO were all toxic to zebrafish embryos to influence embryos hatching and larvae length. Although no obvious morphological malformation and mortality were observed in exposed zebrafish embryos, further studies on the toxicity of the three nanomaterials are still needed.

Nowadays, the prognostic prediction of acute ischemic stroke (AIS) patients is still challenging because of the limited predictive properties of existing models. Blood-based biomarkers may provide additional information to the established prognostic factors. Markers of atherosclerosis have been identified as one of the most promising biomarkers for predicting prognosis, and inflammation, in turn, affects atherosclerosis. According to previous studies, the ratio of monocytes to lymphocytes (MLR) has been reported as a novel indicator of inflammation. Thus, our study was the first to conduct more in-depth research on the relationship between MLR and the prognosis of large artery atherosclerosis (LAA)-type AIS patients. A total of 296 patients with LAA-type stroke were recruited. Of these, 202 patients were assigned to the development cohort, and 94 patients were assigned to the validation cohort. In the development cohort, 202 patients were divided into groups A, B, C, and D according to the quartile method of MLR levels. The one-year prognosis of patients was tracked, and the modified Rankin scale (MRS, with a score ranging from 0 to 6) was mainly selected as the measurement result of the function. The relationship between MLR and prognosis was analyzed by building logistics regression models. The models showed that MLR made significant predictions in poor outcomes of LAA-type stroke patients (odds ratio: 4.037; p = 0.048). At the same time, receiver operating characteristics (ROC) curves were used to compare the predictive values between MLR and clinical prediction score (Barthel Index). This study demonstrated that patients with LAA-type stroke and high MLR had a poor prognosis. MLR might be a reliable, inexpensive, and novel predictor of LAA-type stroke prognosis.
RESUMO
BACKGROUND: This study aimed to evaluate the correlation and consistency between traditional head measurement and structured light three-dimensional (3D) scanning parameters when measuring infant skull shape. METHODS: A total of 76 infants aged 3 months to 2.5 years old were included in the study. Head circumference (HC) was measured with a tape measure. The transverse, anteroposterior, and oblique diameters were measured using a spreading caliper, and the cranial vault asymmetry index (CVAI) and a cranial index (CI) of symmetry were calculated; 76 cases were measured successfully. The above indexes were measured using a structured light 3D scanning system (71 cases were measured with success). Thus, in the end, the valid data of 71 cases were analyzed, and the measurements of the two approaches were compared. RESULTS: The 95% confidence interval of traditional head measurement and structured light 3D scanning was between 0.633 and 0.988. Pearson's correlation coefficient indicated a high correlation between the two methods (r=0.793-0.980). The correlation coefficients of the transverse diameter, anteroposterior diameter, and HC, and the CI of symmetry were higher than 0.9. The lowest correlation coefficient for the CVAI was 0.793. The P values of the above measurement data were all <0.001, which indicated that they were closely related. A Bland-Altman plot indicated reasonable consistency between the two methods. CONCLUSIONS: Both traditional head measurement and structured light 3D scanning are suitable for the measurement of infant head shape. However, while traditional head measurement using a spreading caliper is economical and simple, making it suitable for general screening at a basic level, structured light 3D scanning can deliver additional parameters, which is useful for infants with an abnormal head shape. The latter is also convenient for designing a customized helmet for skull correction when needed.
