The Influence of Breastfeeding Educational Interventions on Breast Engorgement and Exclusive Breastfeeding: A Systematic Review and Meta-Analysis.

BACKGROUND: Breast engorgement and breast pain are the most common reasons for the early cessation of exclusive breastfeeding by mothers. RESEARCH AIMS: (1) To examine the influence of breastfeeding educational interventions on breast engorgement, breast pain, and exclusive breastfeeding; and (2) to identify effective components for implementing breastfeeding programs. METHODS: Randomized controlled trials of breastfeeding educational interventions were searched using five English and five Chinese databases. Eligible studies were independently evaluated for methodological quality, and data were extracted by two investigators. In total, 22 trials were identified, and 3,681 participants were included. A random-effects model was used to pool the results, and a subgroup analysis and meta-regression analysis were conducted. RESULTS: Breastfeeding education had a significant influence on reducing breast engorgement at postpartum 3 days (odds ratio [OR]: 0.27, 95% CI [0.15, 0.48] p < .001), 4 days (OR: 0.16, 95% CI [0.11, 0.22], p < .001), and 5-7 days (OR: 0.24, 95% CI [0.08, 0.74], p = .013) and breast pain (standardized mean difference: -1.33, 95% CI [-2.26, -0.40]) at postpartum 4-14 days. Participants who received interventions had higher odds of exclusive breastfeeding. Breastfeeding educational interventions provided through lecture combined with skills practical effectively reduced breast engorgement (OR: 0.21; 95% CI [0.15, 0.28]; p = .001) and improved exclusive breastfeeding at postpartum 1-6 weeks (OR: 2.16; 95% CI [1.65, 2.83]; p = .001). CONCLUSIONS: Breastfeeding educational interventions have been effective in reducing breast engorgement, breast pain, and improved exclusive breastfeeding. A combination of knowledge and skill-based education has been beneficial for sustaining exclusive breastfeeding by mothers.

Effects of Parental Education on Screen Time, Sleep Disturbances, and Psychosocial Adaptation Among Asian Preschoolers: A Randomized Controlled Study.

PURPOSE: A recent increase in screen time during early childhood has adversely affected the sleep and psychosocial health of children; however, limited information is available regarding effective interventions to reduce the screen time among them. This study aimed to investigate the effect of a parental educational program on screen use, sleep quality, and psychosocial adaptation among preschoolers. DESIGN AND METHODS: A clustered randomized controlled study with a parallel-group design was conducted. Preschoolers with a screen time of ≥2 h/day and their parents were recruited. In total, 14 kindergartens containing 129 parent-child dyads were randomly allocated to either the experimental group (receiving parental education, N = 63 dyads) or the control group (daily activities, N = 66 dyads). Data were collected before and after the intervention. A screen time questionnaire, the Children's Sleep Habits Questionnaire, and the Pediatric Symptom checklist-17 were provided to the participants. A linear mixed-model analysis was performed to examine the efficacy of the intervention. RESULTS: After the intervention, the screen time of children in the experimental group was significantly reduced (effect size: 0.83, p < .001), and they presented improved sleep quality (effect size: 0.57, p = .01) and attention score (effect size: 0.77, p = .02) for psychosocial adaptation. CONCLUSIONS: Parental education is an effective intervention for reducing screen time and improving sleep quality and attention among preschoolers. PRACTICE IMPLICATIONS: Healthcare professionals should consider implementing parental educational programs to reduce screen time, and thus improve the sleep quality and psychosocial health of preschoolers.

Effectiveness of theory-based educational interventions on breastfeeding self-efficacy and exclusive breastfeeding: A systematic review and meta-analysis.

BACKGROUND: Enhancing breastfeeding self-efficacy and intention is crucial for successful breastfeeding. Educational interventions highlighting breastfeeding self-efficacy and breastfeeding plans have been developed to help mothers initiate and sustain breastfeeding practices. RESEARCH AIM: This study aimed to determine whether the use of theory-based educational interventions, i.e., the theory of breastfeeding self-efficacy or theory of planned behavior, is associated with improved breastfeeding outcomes and to identify key factors of effective breastfeeding educational programs. METHODS: We used electronic databases and reference lists of articles to identify published randomized controlled trials of educational programs that adopted the breastfeeding self-efficacy theory or theory of planned behavior. RESULTS: In total, 24 randomized controlled trials were identified, and 5678 mothers were included in those studies, with 4178 mothers in the breastfeeding self-efficacy group and 1500 mothers in the theory of planned behavior group. Mothers who received theory-based interventions had better breastfeeding outcomes for up to 6 months postpartum (standardized mean difference =0.63, 95% confidence interval: 0.34~0.92 for self-efficacy scores at 1~2 months; odds ratio =1.82, 95% confidence interval: 1.27~2.61 for the exclusive breastfeeding rate at 1~2 months; and odds ratio =2.19, 95% confidence interval: 1.24~3.89 for the exclusive breastfeeding rate at 3~6 months). Mothers who were from non-Organization for Economic Co-operation and Development countries, were of older age, had participated in an educational program in a hospital setting, or had used an integrative class format had higher levels of self-efficacy and longer breastfeeding durations to 6 months. CONCLUSIONS: Theory-based educational interventions are effective in improving breastfeeding self-efficacy and exclusive breastfeeding rates at 6 months. Future breastfeeding educational programs incorporating the theories of breastfeeding self-efficacy and planned behavior would be helpful in promoting sustained breastfeeding practices among mothers.

Effects of aromatherapy on sleep quality: A systematic review and meta-analysis.

PURPOSE: The objective of this study was to conduct a systematic review and meta-analysis to examine the effects of aromatherapy on sleep improvements. METHODS: A search of randomized controlled trials was conducted in four English and two Chinese medical electronic databases. Two authors independently performed the search, assessed the methodological quality, and extracted data. Then, final studies were selected after consensus with the third author. RESULTS: In total, 31 trials met the inclusion criteria, of which four had low risk, while the overall bias in 26 was uncertain in terms of methodological quality. The heterogeneity was high among the trials (Q = 341.544, p < 0.001, I2 = 91.216%). There was a significant effect of aromatherapy on sleep quality (Hedges's g = 1.103 (95% confidence interval: 0.813˜1.393, p < 0.001). There was a publication bias (Egger's regression intercept = 7.127, t = 3.055, p = 0.004 and Begg test, Kendall's tau with continuity correction, tau = 0.335 and Z = 2.651, p = 0.008). The subgroup analysis showed that there was a significant difference in the methodological quality among different studies (Q = 18.350, p <  0.001). Sensitivity analyses still revealed high heterogeneity after omitting one study at a time. CONCLUSIONS: The results showed that aromatherapy can be applied by clinical staff to effectively improve sleep quality. However, because there was a high degree of heterogeneity among studies, the inferences of the results need to be applied with caution.

Growth of large-scale nanotwinned Cu nanowire arrays from anodic aluminum oxide membrane by electrochemical deposition process: controllable nanotwin density and growth orientation with enhanced electrical endurance performance.

Densely nanotwinned Cu nanowire (NW) arrays with an identical diameter of ∼55 nm were fabricated by pulse electrochemical deposition at low temperature using anodic aluminum oxide as a template. Different growth orientations of nanotwinned Cu nanowire arrays were investigated. The endurance of the electrical current density before breakdown of the nanotwinned Cu NWs can reach up to 2.4 × 10(8) A cm(-2). The formation of highly dense nanotwins is attributed to relaxation of coalescence induced stress and twin fault stacking when Cu NWs grow by two-dimensional kinetics. A mechanism based on the twinning structure effect on the electromigration was proposed to explain the improved electrical endurance of Cu. The result demonstrates that the formation of nanotwins into Cu NWs can effectively suppress the void growth, leading to extended life time for use in electronic devices.
