Background: The poor coverage of essential maternal services, such as antenatal care (ANC) and skilled delivery care utilization, accounts for higher maternal and infant mortality in low- and middle-income countries (LMICs). Although mobile health (mHealth) interventions could potentially improve the service utilization in resource-limited settings, their effectiveness remains unclear. Objective: This review aimed to summarize the effect of mHealth interventions on improving the uptake of ANC visits, skilled birth attendance at the time of delivery, and facility delivery among pregnant women in LMICs. Methods: We conducted a comprehensive search on 9 electronic databases and other resources from inception to October 2020. We included individual randomized controlled trials and cluster randomized controlled trials that assessed the effectiveness of mHealth interventions for improving perinatal health care utilization among healthy pregnant women in LMICs. We performed a random-effects meta-analysis and estimated the pooled effect size by using risk ratios (RRs) with 95% CIs. In addition, 2 reviewers independently assessed the risk of bias of the included studies by using the Cochrane risk of bias tool and the certainty of the evidence by using the Grading of Recommendation, Assessment, Development and Evaluation approach. Results: A total of 9 studies (10 articles) that randomized 10,348 pregnant women (n=6254, 60.44% in the intervention group; n=4094, 39.56% in the control group) were included in this synthesis. The pooled estimates showed a positive effect of mHealth interventions on improving 4 or more ANC visit utilizations among pregnant women in LMICs, irrespective of the direction of interventions (1-way communications: RR 2.14, 95% CI 1.76-2.60, I2=36%, 2 studies, moderate certainty; 2-way communications: RR 1.17, 95% CI 1.08-1.27, I2=59%, 3 studies, low certainty). Only 2-way mHealth interventions were effective in improving the use of skilled birth attendance during delivery (RR 1.23, 95% CI 1.14-1.33, I2=0%, 2 studies, moderate certainty), but the effects were unclear for 1-way mHealth interventions (RR 1.04, 95% CI 0.97-1.10, I2=73%, 3 studies, very low certainty) when compared with standard care. For facility delivery, the interventions were effective in settings where fewer pregnant women used facility delivery (RR 1.68, 95% CI 1.30-2.19, I2=36%, 2 studies, moderate certainty); however, the effects were unclear in settings where most pregnant women already used facility delivery (RR 1.01, 95% CI 0.97-1.04, I2=0%, 1 study, low certainty). Conclusions: mHealth interventions may contribute to improving ANC and skilled delivery care utilization among pregnant women in LMICs. However, more studies are required to improve their reproducibility and efficiency or strengthen the evidence of different forms of mHealth interventions because of the considerable heterogeneity observed in the meta-analyses.

Bonding is crucial to perinatal mental health. Despite an extensive body of literature on maternal bonding, few studies have focused on paternal bonding. This scoping review aimed to clarify the current state of the concept of paternal–infant/fetus bonding. The eligibility criteria were drawn from the population concept and context elements to answer the following questions: “what is paternal bonding?” and “what are the constructs of the concept of paternal bonding?” The review comprised 39 studies. Paternal bonding was associated with both positive and negative paternal behavior and thought and may be determined based on fathers’ beliefs and rearing history. Most studies showed that father–child interaction is one of the factors promoting paternal bonding. However, fathers generally felt more distant from their babies post-delivery than mothers. Only a few studies originally defined paternal bonding; most relied on the definitions of maternal bonding. We found different descriptions lacking consensus. Few studies examined the differences between paternal and maternal bonding. No consensus exists on the concept, constructs, and assessment of paternal bonding. The causal relationship between paternal bonding and other variables is unexplored. Future studies should explore fathers’ perspectives and experiences, focusing on the unknown aspects of paternal bonding identified in this review.

Background: Despite the potential benefits of effective communication, telling a child that they have a life-threatening condition is one of the most daunting challenges. This study aimed to explore the information needs of children with leukemia from the perspectives of children and their parents at the time of diagnosis.Methods: We conducted an exploratory qualitative study using semi-structured individual interviews with children diagnosed with leukemia between seven and 13 years old (n = 7) and their parents (n = 9). Children and parents’ interview data were analyzed using thematic analysis.Results: We identified three themes for the information needs of children with leukemia, 1) beginning to cope, 2) avoiding disclosure – protecting child, and 3) informational support. The children and their parents needed to receive understandable information at the best time to cope with cancer. However, the children and parents expressed different views about children’s information needs. The children needed clear information about the disease, treatment, hospitalization, and the benefits of hospitalization from the time of diagnosis. In contrast, the parents felt they should not tell their children about the disease if they were in shock by their child’s cancer diagnosis. Moreover, the parents believed that information that would be incomprehensible to the child and distress should be avoided to protect their children.Conclusions: While the information needs of children with leukemia are varied, children and their parents need the information to cope with cancer. However, if the parents believe that the information would be distressful, they might manage communication with their children. Healthcare professionals should explore the motivations behind parents’ attitudes against communication with children and confront conflict. Healthcare professionals also should communicate with the children and their parents to understand their information needs and respect children’s views.

Background: Recently, awareness of children’s decision making has increased in an effort to enhance palliative care. However, the conceptual framework for decision making among children with cancer remains unclear. Aims: We clarified the decision-making process of children with cancer regarding their care, treatment, and support from family and health care professionals, and identified their needs and preferences. Design: We used metaethnography to conduct a metasynthesis of relevant studies. Data sources: We searched PubMed, EMBASE, PsycINFO, MEDLINE, and CINAHL. This report was prepared in accordance with the PRISMA statement. Results: Of the 7,237 retrieved studies, 27 met our inclusion criteria. Four themes emerged that reflected the decision-making process of children with cancer: (a) facing changes brought about by a health threat, (b) preparing for action, (c) asserting one’s choice, and (d) internal and external influences. Conclusion: Children with cancer initially undergo a decision-making process. Respecting children’s preferences, values, and emotions may help build trusting relationships and promote their decision-making capability. Future research should focus on children’s emotions, cognition, development, and interactions with parents and health care professionals.

This systematic review aimed to identify the benefits and possible harms of tocolytic therapy for preterm labour management in the context of pregnant women with extremely preterm birth, multiple gestations, or growth-restricted foetuses. A comprehensive search using MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, CINAHL, and the WHO Global Index Medicus databases was conducted from 10 to 15 July 2021. We included randomized controlled trials and non-randomized studies that assessed the effects of tocolysis compared with placebo or no treatment. We found 744 reports and, finally, nine studies (three randomized controlled trials and six cohort studies) pertaining to women with <28 weeks of gestation were included. No eligible studies were identified among women with a multiple pregnancy or a growth-restricted foetus. A meta-analysis of the trial data showed that there were no clear differences in perinatal death nor for a delay in birth. Non-randomized evidence showed that tocolysis delayed birth by 7 days, though there was no clear difference for preterm birth. In summary, it remains unclear whether tocolytic therapy for inhibiting preterm labour is beneficial for these subgroups of women and their newborns. Further well-designed randomized controlled trials and observational studies are needed to address the lack of evidence regarding tocolytic agents in these populations.
