Effects of implementing non-nutritive sucking on oral feeding progression and outcomes in preterm infants: A systematic review and meta-analysis.

BACKGROUND: Preterm infants have imperfect neurological development, uncoordinated sucking-swallowing-breathing, which makes it difficult to realize effective oral feeding after birth. How to help preterm infants achieve complete oral feeding as soon as possible has become an important issue in the management of preterm infants. Non-nutritive sucking (NNS), as a useful oral stimulation, can improve the effect of oral feeding in preterm infants. This review aimed to explore the effect of NNS on oral feeding progression through a meta-analysis. METHODS: We systematically searched PubMed, CINHAL, Web of Science, Embase, Cochrane databases, China's National Knowledge Infrastructure (CNKI), Wanfang and VIP database from inception to January 20, 2024. Search terms included 'non-nutritive sucking' 'oral feeding' and 'premature.' Eligibility criteria involved randomized controlled studies in English or Chinese. Studies were excluded if they were reviews, case reports, or observational studies from which valid data could not be extracted or outcome indicators were poorly defined. The meta-analysis will utilize Review Manager 5.3 software, employing either random-effects or fixed-effects models based on observed heterogeneity. We calculated the mean difference (MD) and 95% confidence interval (CI) for continuous data, and estimated pooled odds ratios (ORs) for dichotomous data. Sensitivity and publication bias analyses were conducted to ensure robust and reliable findings. We evaluated the methodological quality of randomized controlled trials (RCTs) utilizing the assessment tool provided by the Cochrane Collaboration. RESULTS: A total of 23 randomized controlled trials with 1461 preterm infants were included. The results of the meta-analysis showed that NNS significantly shortened time taken to achieve exclusive oral feeding (MD = -5.37,95%CI = -7.48 to-3.26, p<0.001), length of hospital stay(MD = -4.92, 95% CI = -6.76 to -3.09, p<0.001), time to start oral feeding(MD = -1.41, 95% CI = -2.36 to -0.45, p = 0.004), time to return to birth weight(MD = -1.72, 95% CI = -2.54 to -0.91, p<0.001). Compared to the NNS group, the control group had significant weight gain in preterm infants, including weight of discharge (MD = -61.10, 95% CI = -94.97 to -27.23, p = 0.0004), weight at full oral feeding (MD = -86.21, 95% CI = -134.37 to -38.05, p = 0.0005). In addition, NNS reduced the incidence of feeding intolerance (OR = 0.22, 95% CI = 0.14 to 0.35, p<0.001) in preterm infants. CONCLUSION: NNS improves oral feeding outcomes in preterm infants and reduces the time to reach full oral feeding and hospitalization length. However, this study was limited by the relatively small sample size of included studies and did not account for potential confounding factors. There was some heterogeneity and bias between studies. More studies are needed in the future to validate the effects on weight gain and growth in preterm infants. Nevertheless, our meta-analysis provides valuable insights, updating existing evidence on NNS for improving oral feeding in preterm infants and promoting evidence-based feeding practices in this population.

Clinical efficacy of traditional Chinese medicine therapy for female stress urinary incontinence: a meta-analysis.

OBJECTIVES: To investigate the efficacy of traditional Chinese medicine (TCM) in the treatment of female stress urinary incontinence (SUI). METHOD: PubMed, Cochrane, Web of Science, Embase, CNKI, Wanfang, and VIP databases were searched for articles published up to September 2022. Variables were analyzed using weighted mean difference (WMD), standardized mean difference (SMD), odds ratios (OR), and 95% confidence interval (CI). RESULTS: Eight studies containing 744 patients were included in this study. The results demonstrate that TCM therapy had more advantages in improving the clinical outcome of SUI patients (OR = 2.90, 95%CI:1.92-4.37, P = 0.000), reducing the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) score (WMD = -2.41, 95%CI:-2.83- -1.98, P = 0.000), reducing 1-h urinary pad leakage urine volume (WMD = -1.86, 95%CI:-2.23- -1.49, P = 0.000) and increasing Maximum urethral closure pressure (MUCP) (SMD = 0.86, 95%CI: 0.61-1.11, P = 0.000). CONCLUSION: TCM therapy is effective in improving urinary incontinence symptoms, urodynamics, and quality of life in patients with SUI. This article provides a reference for the application of TCM therapy in women with urinary incontinence.

Factors influencing necrotizing enterocolitis in premature infants in China: a systematic review and meta-analysis.

BACKGROUND: Necrotizing enterocolitis (NEC) is a multifactorial gastrointestinal disease with high morbidity and mortality among premature infants. However, studies with large samples on the factors of NEC in China have not been reported. This meta-analysis aims to systematically review the literature to explore the influencing factors of necrotizing enterocolitis in premature infants in China and provide a reference for the prevention of NEC. METHODS: PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), Wanfang and VIP databases were systematically searched from inception to February 2023. We used Stata14.0 software to perform the systematic review and meta-analysis. We used fixed or random effects models with combined odds ratios (ORs) and 95% confidence intervals (CIs), and quality was evaluated using the Newcastle‒Ottawa Scale (NOS). RESULTS: The total sample was 8616 cases, including 2456 cases in the intervention group and 6160 cases in the control group. It was found that 16 risk factors and 3 protective factors were related to necrotizing enterocolitis in premature infants. Septicemia (OR = 3.91), blood transfusion (OR = 2.41), neonatal asphyxia (OR = 2.46), pneumonia (OR = 6.17), infection (OR = 5.99), congenital heart disease (OR = 4.80), intrahepatic cholestasis of pregnancy (ICP) (OR = 2.71), mechanical ventilation (OR = 1.44), gestational diabetes mellitus (GDM) (OR = 3.08), respiratory distress syndrome (RDS) (OR = 3.28), hypoalbuminemia (OR = 2.80), patent ductus arteriosus (PDA) (OR = 3.10), respiratory failure (OR = 7.51), severe anemia (OR = 2.86), history of antibiotic use (OR = 2.12), and meconium-stained amniotic fluid (MSAF) (OR = 3.14) were risk factors for NEC in preterm infants in China. Breastfeeding (OR = 0.31), oral probiotics (OR = 0.36), and prenatal use of glucocorticoids (OR = 0.38) were protective factors for NEC in preterm infants. CONCLUSIONS: Septicemia, blood transfusion, neonatal asphyxia, pneumonia, infection, congenital heart disease, ICP, GDM, RDS, hypoproteinemia, PDA, respiratory failure, severe anemia, history of antibiotic use and MSAF will increase the risk of NEC in premature infants, whereas breastfeeding, oral probiotics and prenatal use of glucocorticoids reduce the risk. Due to the quantity and quality of the included literature, the above findings need to be further validated by more high-quality studies.

Effect of prophylactic caffeine in the treatment of apnea in very low birth weight infants: a meta-analysis.

OBJECTIVE: The purpose of this meta-analysis is to investigate the effect of prophylactic caffeine use in the treatment of apnea and other clinical outcomes in very low birth weight infants. METHODS: We searched PubMed, Embase, Web of Science, Scopus, EBSCO, CNKI, and Cochrane databases for all relevant studies up to May 20, 2022. The meta-analysis was carried out using Stata16.0 and RevMan5.4 software. RESULTS: Eleven randomized controlled trials were evaluated, including a total of 4375 very low birth weight infants. The results demonstrated that prophylactic caffeine use was linked with a significantly lower probability of AOP (OR 0.31, 95% CI: 0.19-0.49, p < .001), duration of mechanical ventilation and oxygen therapy when compared to the control group. It also reduced the incidence of BPD (OR 0.62, 95% CI: 0.54-0.71, p < .001), PDA (OR 0.49, 95% CI: 0.30-0.80, p = .005) and ROP (OR 0.76, 95% CI: 0.65-0.90, p = .001), without raising the risk of NEC, IVH and death before hospital discharge (p > .05). CONCLUSION: This meta-analysis confirmed the beneficial effects of prophylactic caffeine in preventing apnea of prematurity and improving clinical outcomes.

Prevalence and risk factors of delayed onset lactogenesis II in China: a systematic review and meta-analysis.

BACKGROUND: In 2017, China proposed to achieve the goal that 50% of infants aged 0-6 months should be exclusively breastfed by 2025 proposed by the World Health Assembly in 2012. However, delayed onset lactogenesis II has adverse effects on breastfeeding and thus on neonatal health. There has been no meta-analysis of the prevalence and risk factors of delayed onset lactogenesis II among parturient women in China. To provide best practices, updated evidence-based evidence is needed to supplement reviews on this topic. OBJECTIVE: The purpose of this systematic review and meta-analysis was to quantitatively analyze the prevalence and risk factors of delayed onset lactogenesis II in China. METHODS: We identified relevant studies by searching literature published prior to October 2022 in PubMed, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases for all available observational studies. Stata 16.0 were used for performing the systematic review and meta-analysis. RESULTS: The researchers examined data from 14 observational studies involving 17610 females. The prevalence of delayed onset lactogenesis II from these studies was 31% (95% CI = 25.0%-38.0%, p < .001), and the prevalence showed a significant increasing trend in China over the past decade. The frequency of breastfeeding was >2 times per day at 24-48 h after delivery was one protective factor against delayed onset lactogenesis II (OR = 0.41). The significant risk factors for delayed onset lactogenesis II were breastfeeding initiation > 30min after birth (OR = 1.31), maternal age > 35 years (OR = 2.19), primiparous women (OR = 2.38), maternal overweight/obesity (OR = 2.22), cesarean section (OR = 1.33), anxiety (OR = 3.23), depression (OR = 3.21) and gestational hypertension (OR = 3.43). CONCLUSIONS: There is a high incidence of delayed onset lactogenesis II in Chinese parturient women. We identified eight risk factors and one protective factor for DOL II. These findings suggest health care professionals should pay attention to these risk parturients so as to better provide early preventive interventions to increase the breastfeeding rate.

Comparative efficacy and safety of caffeine citrate and aminophylline in treating apnea of prematurity: A systematic review and meta-analysis.

BACKGROUND: Methylxanthine, including caffeine citrate and aminophylline, is the most common pharmacologic treatment for apnea of prematurity. However, due to the lack of high-quality evidence, there are no clear recommendations or guidelines on how to choose between caffeine and aminophylline. OBJECTIVE: This meta-analysis aimed to assess the comparative efficacy and safety of caffeine and aminophylline for apnea of prematurity, and provide reliable evidence for clinical medication in the treatment for apnea of prematurity. METHODS: PubMed, Scopus, Embase, EBSCO, Web of Science, and Cochrane databases were systematically searched from May 1975 to June 2022. RESULTS: Ten studies including a total of 923 preterm infants were evaluated. Our results showed that there was no significant difference in the effective rate of 1-3days between caffeine and aminophylline (OR 1.05, 95%CI: 0.40-2.74, P = 0.914). However, for side effects such as tachycardia (OR 0.22, 95%CI: 0.13-0.37, P<0.001) and feeding intolerance (OR 0.40, 95%CI: 0.23-0.70, P = 0.001), the incidence rate was lower in the caffeine group compared with the aminophylline group. No significant difference was found in hyperglycemia (OR 0.45, 95%CI: 0.19-1.05, P = 0.064). CONCLUSION: This meta-analysis reveals that caffeine citrate and aminophylline have similar therapeutic effectiveness on respiratory function, but caffeine has fewer side effects and should be considered first for treatment.

Effects of different doses of synthetic oxytocin on neonatal instinctive behaviors and breastfeeding.

Synthetic oxytocin is the current domestic first-line agent of induced labor and labor augmentation, and its potential effects on neonatal neurobehavioral development is currently attracting increased attention. To explore the effect of different doses of synthetic oxytocin on neonatal instinctive breastfeeding behavior and breastfeeding by observing neonatal behaviors during skin-to-skin contact with mothers after delivery. Observations and comparisons of neonatal instinctive behaviors were conducted by using Widström's 9 Stages method. According to the total dosage of oxytocin administered during labor, participants were divided into a low dose group (≤ 2.5 U) of 39 pairs, a medium dose group (> 2.5 U) of 38 pairs, a high dose group (> 7.5 U) of 38 pairs and a control group (no synthetic oxytocin use) of 39 pairs. The occurrence time of newborns' instinctive movements and the duration of each behavior stage for the four groups were also analyzed. The number of exclusive breastfeeding sessions within 3 days after birth and the rate of exclusive breastfeeding at 3 months were collected and compared. There were significant differences among the four groups in the occurrence time of raising head or turning head (p = 0.004), eating hands (p = 0.011), moving body (p = 0.001), locating areola (p < 0.001), licking nipples (p = 0.002), containing nipple (p = 0.001), sucking (p < 0.001). There were significant differences among the four groups in the duration of activity (p = 0.004), clawing (p = 0.001), familiarization (p = 0.001), and sucking (p < 0.001). There was also a significant difference in the number of exclusive breastfeeding sessions of 24 h (p = 0.011), 48 h (p < 0.001), 72 h (p = 0.001) after birth among the four groups, but there was no statistical difference in the rate of exclusive breastfeeding at 3 months after birth. The intrapartum administration of synthetic oxytocin was associated with the expression of neonatal instinctive breastfeeding. With increases in drug dose, the effect of breast seeking activity and breast attachment was more significant, and the association of synthetic oxytocin on sucking and breastfeeding was dose-dependent.

Efficacy of propylthiouracil in the treatment of pregnancy with hyperthyroidism and its effect on pregnancy outcomes: A meta-analysis.

BACKGROUND: Hyperthyroidism affects about 0.2%-2.7% of all pregnancies, and is generally treated with propylthiouracil (PTU). However, previous studies about the effects of propylthiouracil on maternal or foetal are contentious. OBJECTIVE: This meta-analysis was carried out to investigate the safety and efficacy of propylthiouracil during pregnancy. MATERIALS AND METHODS: PubMed, EBSCO, Embase, Scopus, Web of Science, Cochrane, CNKI, Wanfang and VIP database were searched from inception until August 31, 2021 for all available randomized controlled trials (RCTs) or cohort studies that evaluated the efficacy of propylthiouracil and its effects on pregnancy outcomes. Odds ratio (OR) and 95% confidence interval (CI) were used for binary variables, weighted mean difference (WMD) and 95% confidence interval (CI) were used for continuous variables. RevMan5.4 and Stata 16.0 were used for performing the meta-analysis. RESULTS: The researchers examined data from 13 randomized controlled trials and cohort studies involving 18948 infants. Congenital anomalies were not significantly associated with PTU in the pooled results (OR = 1.03, 95%CI: 0.84-1.25, P = 0.80, I2 = 40.3%). There were no statistically significant differences in neonatal hypothyroidism (OR = 0.55, 95%CI: 0.06-4.92, P = 0.593, I2 = 57.0%) or hepatotoxicity (OR = 0.34, 95%CI: 0.08-1.48, P = 0.151, I2 = 0.0%) exposed to PTU compared to the control group. The serum levels of FT3, FT4, TT3, and TT4 were significantly lower in the propylthiouracil group compared to the control group. CONCLUSION: This meta-analysis confirmed the beneficial effects of propylthiouracil treatment, namely the risks of adverse pregnancy outcomes were not increased, and it also proved PTU's efficacy in the treatment of pregnant women with hyperthyroidism. The findings supported the use of propylthiouracil during pregnancy with hyperthyroidism in order to improve clinical pregnancy outcomes in patients with thyroid dysfunction.
