Background: Mobile health (mHealth) interventions promoting healthy lifestyle changes offer an adaptable and inexpensive method for accessing health information but require cultural appropriateness and suitability for acceptance and effectiveness in Indigenous populations. No systematic review on effective mHealth interventions for Indigenous women during pregnancy and the early childhood years has been conducted. Objective: This review evaluated the effectiveness of mHealth interventions promoting healthy behaviors for Indigenous mothers and children from conception to 5 years post partum. It also aimed to explore the observed effectiveness differences based on participant engagement, intervention design, and provision of context. Further, the review explored if the interventions were co-designed. Methods: A systematic search of 5 databases was conducted: SCOPUS, MEDLINE, CINAHL, PsycINFO, and ProQuest (Dissertation or Thesis). Studies were included if they were either a randomized controlled trial, pre-post comparison, or a cohort study using mHealth with Indigenous women for maternal and child health following a preregistered PROSPERO protocol (CRD42023395710). HealthInfoNet was searched for gray literature and the reference lists of included studies were hand searched. The initial title and abstract screen for eligibility were performed by 1 reviewer. A full-text screen of eligible studies and a quality appraisal of included studies was performed by 2 reviewers independently. The appraisal tools used were the Mixed Methods Quality Appraisal Tool and the Centre of Excellence in Aboriginal Chronic Disease Knowledge Translation and Exchange (CREATE). A descriptive synthesis of the extracted data was performed. Results: Of the 663 articles screened, only 3 met the eligibility criteria. Each paper evaluated a different mHealth intervention: Remote Prenatal Education; the SMS Parent Action Intervention (two-way text messaging); and the Screening, Brief Intervention and Referral to Treatment (SBIRT) eCHECKUP To Go (web-based screening and intervention). Statistically significant changes were reported in some outcomes, including an increase in the parental participation rate in face-to-face prenatal education; increased rate of breastfeeding initiation and exclusive breastfeeding (2-12 months); improved overall children's behavior related to sleep, diet, physical activity, screen time, and intake of sugary beverages; improved individual children's behavior related to physical activity and sleep; and decrease in alcohol drinks per week and binge drinking episodes per 2 weeks due to time effect. However, no study provided a sample size calculation for the reported significant outcomes. Also, due to the small number of included studies and each study evaluating a different intervention, it was not possible to combine results to ascertain if the participant engagement, intervention design, or community context had any impact on the effectiveness. Conclusions: Due to the lack of sample size calculation, it was not possible to establish whether differences in the effectiveness were due to the interventions or a type I statistical error. Therefore, caution is required in the interpretation of these findings. Trial registration: PROSPERO CRD42023395710; https://www.crd.york.ac.uk/PROSPERO/view/CRD42023395710.

Women with problematic substance use are frequently referred to interventions to promote positive parenting. Parenting interventions that attend to the unique risks faced by this population may enhance engagement and outcomes. While reviews of extant parenting interventions in the research literature have been undertaken, no studies have examined parenting interventions being implemented in community practice and the extent to which these are informed by current research. We systematically compared parenting interventions offered in 12 maternal substance use treatment programs in one Canadian province with those described in the research literature (K = 21). Few parenting interventions were replicated, either within or across the two samples. However, parenting interventions within both samples were largely similar in their objectives. Across both research and community samples, approximately half of the interventions were developed or adapted for a problematic substance use population. Parenting knowledge, psychosocial risk, and maternal emotional regulation were most commonly addressed. Risks pertaining to the impact of drug craving and substance-related changes in neurobiology associted with parenting were less commonly addressed. Findings highlight current strengths and limitations of parenting interventions within research and community settings, with recommendations offered for future research and knowledge translation.

Objective: The aim of this study was to demonstrate the association between maternal asthma and the risk of hypertensive disorders of pregnancy.Methods: A systematic search of seven databases was conducted. A meta-analysis was performed to calculate risk ratios and 95% CI using random-effects models.Results: Asthma was associated with an increased risk of pregnancy-induced hypertension (RR 1.45, 95%CI 1.29-1.63), transient hypertension of pregnancy (RR 2.00, 95%CI 1.52-2.63), preeclampsia or eclampsia (RR 1.28, 95%CI 1.25-1.32), preeclampsia (RR 1.43, 95%CI 1.31-1.57) and eclampsia (RR 1.56, 95%CI 1.13-2.15).Conclusion: The meta-analysis illustrated that asthma was significantly increased risk of hypertension during pregnancy.

Background: Gastric cancer is the third leading cause of cancer death in the world. The benefit of adjuvant chemotherapy has been demonstrated by published individual patient data meta-analysis and Cochrane systematic review. However, there is no consensus on which is the optimal adjuvant chemotherapy regimens. Present network meta-analysis aims to compare the differences of effect between all available adjuvant chemotherapy regimens in improving overall survival and disease-free survival, and to rate the certainty of evidence from present network meta-analysis. Methods: We will conduct this systematic review and network meta-analysis using Bayesian method and according to Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) statement. We will search PubMed, EMBASE.com, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese National Knowledge Infrastructure (CNKI), and Chinese Biological Medical Database (CBM), and ClinicalTrials.gov () to identify randomized controlled trials (RCTs) comparing adjuvant chemotherapy to surgery alone. We will assess the risk of bias of individual RCTs using a modified version of Cochrane tool. We will also use the advance of GRADE to rate the certainty of network meta-analysis. Data analysis will be performed with R-3.4.1 and WinBUGS software. Results: The results of this study will be published in a peer-reviewed journal. Discussion: To the best of our knowledge, this systematic review and network meta-analysis will firstly use both direct and indirect evidence to compare the differences of all available adjuvant chemotherapy regimens for resected gastric cancer patients. This is a protocol of systematic review and meta-analysis, so the ethical approval and patient consent are not required.
