Preterm birth represents a major obstetric complication. This study aimed to assess the efficacy of a meditation programme in the prevention of preterm birth. This study was a randomized controlled trial without blinding. The study was performed at Udonthani Hospital in Northeast Thailand. A total of 199 eligible participants were randomly assigned to a five-step mindfulness meditation programme (n=84) or a control group (n=115). The control group received routine prenatal care. The meditation and control group subjects did not differ on a wide variety of sociodemographic characteristics, or in terms obstetric history and prior meditation experience. The data were analyzed on an intention-to-treat basis after delivery, using less than 37 weeks as the criterion for a preterm birth. Other outcome variables included a subjective measure of symptoms of stress. The preterm birth rate for the meditation group was significantly less than that for the control group (6.0% vs. 15.7%, p=0. 037). The stress scores reported by the meditation group markedly decreased over time (p<0.001), while the control group scores showed no change (p=0.375). The results confirm and strengthen the findings of past research indicating that participation in a meditation programme can reduce symptoms of stress. Meditation appears to be a promising technique for reducing the incidence of preterm birth. Recommendations are made for future research in this area.

OBJECTIVETo estimate the effect of early intervention with aspirin for prevention of preeclampsia in high-risk women.

METHODSA systematic review and meta-analysis were performed based on the principles and methods of Cochrane systematic reviews. Electronic databases were searched for randomized trials comparing aspirin with either placebo or no aspirin. Studies were included when meeting the inclusion criteria that the participants were pregnant women at a high risk of preeclampsia and started aspirin therapy at 16 gestational weeks or earlier, which were assessed by two independent reviewers. Meta-analysis was conducted using Review Manger 5.3 software.

RESULTSA total of 5 studies involving 860 participants were included in the final analysis. In the high-risk women, early use of aspirin showed an OR of 0.35 (95% CI 0.17-0.75) for preventing pregnancy-induced hypertension (PIH), 0.75 (95% CI 0.47-0.98) for preeclampsia, 0.53 (95% CI 0.29-0.98) for intrauterine growth retardation, and 0.20 (95% CI 0.08-0.48) for preterm birth; the average birth weight in aspirin intervention group was 107.15 g (95% CI 76.13-138.18, P<0.001) more than that in the control group.

CONCLUSIONIn high-risk pregnancies, early aspirin intervention starting before 16 weeks of gestation can prevent PIH, preeclampsia, IUGR, and preterm birth and help to increase the birth weight.

Objective: To investigate the clinical effect and the influencing factors of ultrasound-indicated cerclage and history-indicated cerclage in singleton gestation. Methods: The clinical data of 272 singleton pregnant women with cervical incompetence who underwent McDonald cervical cerclage due to medical history indication (history-indicated group) or ultrasound indication (ultrasound-indicated group) in Peking University First Hospital from January 2010 to February 2021 were retrospectively analyzed. The general clinical data and maternal and fetal outcomes were compared between the history-indicated group (141 cases) and ultrasound-indicated group (131 cases). According to the gestational age at delivery, 272 pregnant women who underwent cervical cerclage were further divided into ≥34 weeks group (225 cases) and <34 weeks group (47 cases), and the influencing factors of preterm birth before 34 weeks of gestation were analyzed. Results: (1) The median gestational age at cerclage was 16.6 weeks in the history-indicated group and 23.4 weeks in the ultrasound-indicated group, and the median gestational age extension at delivery was 21.4 weeks and 14.7 weeks, respectively, with statistically significant differences between the two groups (all P<0.05). (2) The full-term birth rate was 76.6% (108/141) in the history-indicated group and 71.0% (93/131) in the ultrasound-indicated group, the live birth rate was 97.2% (137/141) and 97.7% (128/131), and the median birth weight of live birth was 3 155 g and 3 055 g, respectively. The differences were not statistically significant (all P>0.05). Among 272 pregnant women with cervical cerclage, 265 neonates survived (97.4%, 265/272). The gestational age of 7 pregnant women who did not have live birth was ≤25 weeks of gestation (range: 19⁺¹-25 weeks), and they were all clinically infected or confirmed chorioamnionitis or pathogenic microorganisms carrying during pregnancy, and their families gave up. The minimum birth weight of the surviving neonate was 850 g (gestational week of delivery was 26⁺⁶ weeks). (3) Univariate analysis showed that compared with ≥34 weeks group, the body mass index (BMI) of pregnant women in <34 weeks group was higher at 6-7 weeks of gestation (median: 24.5 vs 25.4 kg/m²), shorter cervical length (CL) at 1-2 weeks after surgery [(31.1±8.4) vs (26.1±11.0) mm], shorter CL at 26-28 weeks of gestation after surgery (median: 26.3 vs 16.0 mm), and higher incidence of elevated C-reactive protein (CRP) before and after surgery and before delivery. The differences were all statistically significant (all P<0.05). Multivariate logistic regression analysis showed that preterm birth before 34 weeks was negatively associated with CL at 26-28 weeks of gestation after cerclage (OR=0.902, 95%CI: 0.858-0.947; P<0.001), and was positively correlated with elevated CRP before delivery (OR=3.492, 95%CI: 1.652-7.381; P=0.001). There were no significant correlations between preterm birth and preoperative or postoperative CRP elevation, CL at 1-2 weeks after surgery, and BMI at 6-7 weeks of gestation (all P>0.05). Conclusions: Cervical cerclage for singleton pregnant women with cervical incompetence indicated by history or ultrasound both have good clinical efficacy, and there is no significant difference in maternal and fetal outcomes between the two groups. CL at 26-28 weeks of gestation and CRP before delivery are risk factors for preterm birth before 34 weeks of gestation after cervical cerclage.

There is a relatively high incidence rate of invasive fungal infection (IFI) in preterm infants admitted to the neonatal intensive care unit (NICU), and early diagnosis of IFI is difficult in clinical practice. The patients developing IFI tend to have severe conditions, a long course of treatment, high hospital costs, high mortality, and poor prognosis, and therefore, the prevention of IFI is of particular importance. At present, fluconazole is often used as the first-line drug for the prevention of IFI in preterm infants, but no consensus has been reached on the specific dose and course of treatment, and there are still controversies over the targeted population and prophylactic effect. This article reviews the recent research on the pharmacological prevention strategies for IFI in preterm infants in the NICU, so as to provide a reference for clinicians.

OBJECTIVE: To study the efficacy of probiotics in preventing late-onset sepsis (LOS) in very low birth weight (VLBW) infants. METHODS: Databases including PubMed, Web of Science, Cochrane Library, Wanfang Data, China National Knowledge Infrastructure, and Chinese Biomedical Literature Database were searched for randomized controlled trials (RCTs) of probiotics in preventing LOS in VLBW infants. LOS was classified as clinical LOS and confirmed LOS. RevMan 5.4 was used to perform the Meta analysis. RESULTS: A total of 31 RCTs were included, with 3 490 VLBW infants in the probiotics group and 3 376 VLBW infants in the control group. The Meta analysis showed that compared with the control group, the probiotics group had significantly lower risks of clinical LOS ( CONCLUSIONS Current evidence indicates that probiotics may reduce the risk of clinical LOS and clinical/confirmed LOS in VLBW infants, and the risk of confirmed LOS in VLBW infants who are exclusively breastfed.

To evaluate the effectiveness of intervention plans developed by the evidence base multi-discipline critical strategies (EBPCS) on temperature and clinical outcomes in very preterm infants (VPIs) born at<32 weeks. Clinical data were collected from VPIs born in the delivery room/operating room of Chengdu Women's and Children's Central Hospital from May 1, 2021, to May 31, 2022, who required immediate temperature management and were transferred to the neonatal intensive care unit (NICU) of the hospital. The study population was randomly divided into a control group and an intervention group based on the random number table method, with 108 cases in each group. The control group implemented the conventional temperature management recommended by domestic guidelines, while the intervention group adopted EBPCS interventions compared to the control group. The differences in body temperature and clinical outcomes between the two groups were compared after the implementation of different temperature management strategies. A total of 216 VPIs were included. The intervention group had a lower incidence of hypothermia (30.55% vs. 87.03%, P<0.001), higher mean body temperature admitted to the NICU [(36.56±0.31) ℃ vs. (35.77±0.53) ℃, P<0.001], a lower dose of pulmonary surfactant [(115.94±36.96) mg/kg vs. (151.41±54.68) mg/kg, P=0.014], shorter duration of mechanical ventilation [(5.77±1.26) days vs. (14.19±4.63) days, P=0.006], and lower incidence of intraventricular haemorrhage (12.04% vs. 23.15%, P=0.032). The implementation of temperature intervention strategies developed by the EBPCS for VPIs after birth could prevent and reduce the incidence of hypothermia and improve clinical outcomes.

Objective: To investigate the clinical efficacy of modified Shirodkar transvaginal cervical cerclage (TVCC) in the treatment of cervical insufficiency (CI) and its impact on maternal and fetal outcomes. Methods: The clinical data of 218 pregnant women with CI admitted to Fu Xing Hospital, Capital Medical University from January 1, 2015 to August 31, 2021 was retrospectively analyzed. According to different surgical approaches, they were divided into modified Shirodkar TVCC treatment during pregnancy (TVCC group, 108 cases) and non-pregnant women underwent laparoscopic cervical cerclage (LACC) treatment (LACC group, 110 cases). The clinical data and pregnancy outcomes of the two groups were compared. Furthermore, the two groups of pregnant women were stratified according to cervical length (CL) to explore the effects of the two surgical methods on the pregnancy outcomes of CI women with different CL. Results: (1) Related indicators before and during cerclage: there were no complications such as massive hemorrhage, bladder injury and anesthesia accident in the two groups of pregnant women during cerclage. Compared with the LACC group, TVCC group had longer preoperative CL [(2.3±0.6) vs (2.7±0.6) cm], more intraoperative blood loss [(7.5±0.5) vs (14.4±1.4) ml] and longer hospital stay [(6.0±0.1) vs (7.3±0.4) day]. However, the operation time was shorter [(42.9±1.6) vs (25.9±1.4) minute] and the hospitalization cost was less [(9 912±120) vs (5 598±140) yuan], and the differences were statistically significant (all P<0.05). (2) Pregnancy outcomes: live birth rates were 95.4% (103/108) in the TVCC group and 96.4% (106/110) in the LACC group, showing no significant difference between the two groups (χ²=2.211, P=0.232). The preterm birth rate (12.0%, 13/108) in the TVCC group was higher than that in the LACC group (7.3%, 8/110), the neonatal birth weight was lower than that in the LACC group [(3 006±96) vs (3 225±42) g], and the proportion of low birth weight infants was higher than that in the LACC group [15.5% (16/103) vs 1.9% (2/106)], and the differences were statistically significant (all P<0.05). (3) Stratified analysis of CL: for pregnant women with CL<2.0 cm, the miscarriage rate of the TVCC group was higher than that of the LACC group (2/9 vs 3.0%), and the live birth rate was lower than that of the LACC group (7/9 vs 97.0%), and the differences were statistically significant (all P<0.05). For CL 2.0-<2.5 cm, 2.5-<3.0 cm, CL≥3.0 cm, there were no statistically significant differences in preterm birth rate and live birth rate between the two groups (all P>0.05). Conclusions: Modified Shirodkar TVCC is simple and easy to operate, which significantly reduces the cesarean section rate and medical cost compared with LACC, and there is no significant difference in the live birth rate. When there is inevitable late abortion, laparoscopic cerclage removal does not need to be performed again, which could reduce the second operation and is worthy of clinical application.

OBJECTIVES: To investigate whether evidence-based standardized nutrition protocol can facilitate the establishment of full enteral nutrition and its effect on short-term clinical outcomes in very preterm/very low birth weight infants. METHODS: A retrospective analysis was performed on the medical data of 312 preterm infants with a gestational age of ≤32 weeks or a birth weight of <1 500 g. The standardized nutrition protocol for preterm infants was implemented in May 2020; 160 infants who were treated from May 1, 2019 to April 30, 2020 were enrolled as the control group, and 152 infants who were treated from June 1, 2020 to May 31, 2021 were enrolled as the test group. The two groups were compared in terms of the time to full enteral feeding, the time to the start of enteral feeding, duration of parenteral nutrition, the time to recovery to birth weight, the duration of central venous catheterization, and the incidence rates of common complications in preterm infants. RESULTS: Compared with the control group, the test group had significantly shorter time to full enteral feeding, time to the start of enteral feeding, duration of parenteral nutrition, and duration of central venous catheterization and a significantly lower incidence rate of catheter-related bloodstream infection (P<0.05). There were no significant differences between the two groups in the mortality rate and the incidence rate of common complications in preterm infants including grade II-III necrotizing enterocolitis (P>0.05). CONCLUSIONS Implementation of the standardized nutrition protocol can facilitate the establishment of full enteral feeding, shorten the duration of parenteral nutrition, and reduce catheter-related bloodstream infection in very preterm/very low birth weight infants, without increasing the risk of necrotizing enterocolitis.
