Hope is one of the theological virtues strongly emphasized by Pope Francis, especially in the context of a world marked by suffering, crisis, and uncertainty. This article aims to present the Christian theological understanding of hope according to Pope Francis and to explore its relevance for the Church as it prepares for the Jubilee Year 2025. This study employs a documentary and textual theological analysis of Pope Francis’ catecheses, Sacred Scripture, official Church teachings, and the Jubilee documents. The findings show that Christian hope is rooted in the experience of God who accompanies, liberates, and consoles His people, and is grounded in the Paschal Mystery and the resurrection of Christ. Pope Francis deepens this vision through the figures of Sacred Scripture and through existential dynamics such as learning to hope, resisting despair, and remaining vigilant. Hope is both personal and ecclesial, as the Church is called to be a missionary of hope for the world. These insights highlight the importance of ongoing formation in the faith and concrete works of mercy as expressions of hope, especially as the Church enters the Jubilee Year 2025 as Pilgrims of Hope.

Nausea and vomiting are common symptoms experienced during early pregnancy, especially in the first trimester, and can adversely affect maternal comfort, nutritional intake, and overall well-being. In primary health care settings, these symptoms are often managed with pharmacological treatments; however, such approaches may raise concerns regarding safety, potential side effects, and accessibility for pregnant women. Therefore, there is increasing interest in non-pharmacological interventions that are safer and more practical. One alternative method is lemon aromatherapy (Citrus limon), which is believed to reduce nausea and vomiting by stimulating the olfactory system and promoting a relaxing effect. This study aimed to assess the effectiveness of lemon aromatherapy in decreasing the frequency of nausea and vomiting among first-trimester pregnant women diagnosed with emesis gravidarum at the Rum Balibunga Community Health Center. The research applied a pre-experimental design using a one-group pretest–posttest approach. A total of 30 pregnant women in their first trimester were selected through purposive sampling. The intervention involved inhalation of lemon aromatherapy over a specified duration. Data on the frequency of nausea and vomiting were collected before and after the intervention using a structured observation instrument. The data were analyzed using both descriptive and inferential statistics, with the Wilcoxon signed-rank test employed to determine differences between pre- and post-intervention results. The findings revealed a significant reduction in nausea and vomiting frequency after the intervention. Overall, lemon aromatherapy proved to be an effective, safe, and practical non-pharmacological option to support antenatal care services.

Background: Early Breastfeeding Initiation (IMD) is the practice of allowing newborns to breastfeed within the first hour after birth. This practice is not only beneficial for establishing mother-infant bonding but also plays a crucial role in stimulating uterine contractions through the release of oxytocin, which can accelerate uterine involution in postpartum mothers. Uterine involution is an important physiological process that prevents postpartum hemorrhage and supports maternal recovery. Despite the known benefits, not all mothers practice IMD immediately after delivery, which may affect the process of uterine involution. Objective: This study aimed to analyze the relationship between Early Breastfeeding Initiation (IMD) and the incidence of uterine involution in postpartum mothers at the Benao Community Health Center Work Area. Methods: A quantitative, observational study with a cross-sectional design was conducted involving 30 postpartum mothers selected through purposive sampling. Data were collected on IMD practices and uterine involution assessments. The Wilcoxon signed-rank test was used to analyze the relationship between IMD and uterine involution. Results: The study found a significant relationship between IMD and uterine involution (p = 0.000). Mothers who practiced IMD within the first hour postpartum showed a faster and more effective uterine involution process compared to those who did not. Conclusion: Early Breastfeeding Initiation (IMD) is significantly associated with the incidence and speed of uterine involution in postpartum mothers. Promoting IMD immediately after birth is essential for supporting maternal recovery and preventing postpartum complications

The maternal mortality rate in Indonesia remains high, reaching 305 per 100,000 live births in 2021, with one contributing factor being the lack of maternal knowledge regarding pregnancy danger signs. Prenatal classes are considered a strategic intervention to improve pregnant women’s understanding of critical warning signs such as bleeding, severe abdominal pain, and infection symptoms. This study aims to analyze the influence of pregnancy classes on pregnant women’s knowledge of danger signs. The research employed a quantitative design with a cross-sectional approach involving 30 pregnant women selected through purposive sampling at several community health centers. Data were collected using validated and reliable questionnaires, with measurements conducted before (pre-test) and after (post-test) participants attended at least three prenatal classes. Data analysis used descriptive statistics and the Wilcoxon Signed Rank Test with SPSS. The results showed that most respondents were aged 20–35 years (63.3%), had a high school education (36.7%), were housewives (60.0%), and multigravida (56.7%). Before the intervention, 50% had poor knowledge and only 20% had good knowledge. After attending prenatal classes, 63.3% achieved good knowledge, while only 10% remained in the poor category. The Wilcoxon test showed a significant difference (p = 0.000). Thus, prenatal classes effectively improve knowledge and support early detection of complications, potentially reducing maternal and infant mortality rates.

The active phase of labor is a crucial stage that determines the progress and success of the delivery process. Prolonged labor during this phase can increase the risk of maternal complications and reduce the comfort of the laboring mother. Various non-pharmacological interventions have been developed to support the physiological progress of labor, including acupressure at the SP6 point and oxytocin massage. This study aims to analyze the differences in the effects of SP6 acupressure and oxytocin massage on the duration of the active phase of labor at the Galala Health Center in the Tidore Islands. This study used a quasi-experimental design with a comparative approach in two intervention groups. The sample consisted of 40 mothers in the first stage of active labor who met the inclusion criteria, with 20 respondents in the SP6 acupressure group and 20 respondents in the oxytocin massage group. The duration of the first stage of labor was calculated from 4 cm cervical dilation to complete 10 cm dilation and recorded using a partograph. Data were analyzed univariately to describe the distribution of labor duration and bivariately using the Mann–Whitney U test to assess the difference between the two groups. The results showed that the median duration of the first stage of labor in the SP6 acupressure group was shorter than in the oxytocin massage group. The Mann–Whitney test showed a statistically significant difference between the two intervention groups (p < 0.05). The conclusion of this study indicates that SP6 acupressure is more effective than oxytocin massage in shortening the duration of the first stage of active labor. These findings support the use of SP6 acupressure as a safe and effective nonpharmacological intervention in intrapartum midwifery care in primary health care facilities.

Early mobilization is an important component of postpartum midwifery care to prevent complications, accelerate physical recovery, and improve maternal comfort after delivery. However, not all mothers are able to perform early mobilization optimally due to fatigue, pain, and decreased energy after delivery. Sukari date palm juice (Extractum Phoenix dactylifera) is known to contain simple carbohydrates, minerals, and bioactive compounds that have the potential to increase energy and accelerate maternal recovery. This study aims to analyze the effect of consuming Sukari date palm juice on accelerating early mobilization of postpartum mothers from day 1 to day 3 in the working area of ​​the Sikui Community Health Center (UPT). The study used a quasi-experimental design with a pretest–posttest control group approach. The study sample consisted of 30 postpartum mothers divided into an intervention group (n=15) and a control group (n=15). Early mobilization ability was assessed based on the time the mother was able to sit, stand, and walk. The results showed that postpartum mothers in the intervention group experienced a significant acceleration in early mobilization compared to the control group, particularly in walking ability, with a time difference of up to 8–12 hours faster. The results of the Mann–Whitney statistical test showed a significant effect of date palm juice consumption on the acceleration of early mobilization (p < 0.001). Thus, Sukari date palm juice has been proven to be effective in accelerating early mobilization and can be recommended as a supporting nutritional intervention in postpartum midwifery care.

Preterm birth remains a significant public health concern due to its contribution to neonatal morbidity and mortality worldwide. Among the various risk factors, maternal infections—particularly sexually transmitted infections (STIs)—have been identified as preventable yet critical determinants of premature delivery. This study aimed to examine the relationship between STIs and preterm birth among mothers receiving care at Tomalou Primary Health Care Center. A cross-sectional analytical design was employed, involving 30 postpartum mothers whose medical records and antenatal care data were available. Data on STI status and birth outcomes were collected from health center records and laboratory results, while maternal demographic and obstetric characteristics were also documented. Results indicated that 40% of participants were diagnosed with STIs during pregnancy, and 33.3% experienced preterm birth. Chi-square analysis revealed a significant association between maternal STI status and preterm delivery (p = 0.003). Logistic regression demonstrated that mothers with STIs were sixteen times more likely to deliver prematurely compared to uninfected mothers (OR = 16.0; 95% CI: 2.45–104.3; p = 0.002). These findings suggest that STIs represent a substantial risk factor for preterm birth, even among mothers with adequate antenatal care attendance. Early detection, timely treatment, and comprehensive reproductive health education are recommended to reduce infection-related adverse outcomes. Strengthening STI screening and management within primary healthcare settings is essential to improve maternal and neonatal health outcomes. This study provides evidence for the importance of integrating infection prevention strategies into routine antenatal care to mitigate the risk of premature delivery.
