With the aging of the population and changes in family structure, optimizing home safety monitoring systems for older adults and children—two major vulnerable groups—has become a critical issue in public health and social sciences. This article systematically compares the advantages and limitations of traditional manual monitoring and intelligent technologies. It reveals that traditional models, which rely heavily on human resources, are associated with high costs and inconsistent quality. In contrast, intelligent devices face challenges such as privacy risks, high expenses, and limited user adaptability. Looking forward, this study proposes the integration of a "medical-nursing-family" collaborative mechanism with telemedicine technologies. Through technological innovation, policy support, and social cooperation, a multi-level monitoring network should be established to balance safety effectiveness with humanistic care.

Objective:To explore the application of the flipped classroom teaching method in pediatric internship, evaluate the feedback from both students and faculty, and provide evidence for optimizing clinical medical education strategies.Methods:Fourth-year students ( n=174) enrolled in 2019 in the eight-year clinical medicine program at Peking University Health Science Center and instructors ( n=42) participated in this study. Questionnaire survey and exit examination scores were used to assess the effectiveness of the flipped classroom method. A statistical analysis was performed using SPSS 26.0. Kruskal-Wallis test and Dunn's multiple comparisons were used to evaluate the differences in satisfaction across teaching components. Chi-square test and Fisher's exact test were applied to compare satisfaction between high-score (top 30%) and low-score (bottom 30%) student groups. Results:①Overall student satisfaction with the flipped classroom reached 91.33% ("very satisfied" + "satisfied"). High satisfaction was reported for pre-class self-learning videos (80.35%), recommended clinical guidelines (82.80%), and English literature (71.10%), while satisfaction with the flipped classroom lectures was comparatively low (52.60%), with significant differences compared to other components ( P<0.05). ②High-score students exhibited significantly lower satisfaction than low-score students across all components (overall evaluation, 84.61% vs. 98.08%, Fisher's exact test, P=0.031; pre-class videos, 53.85% vs. 76.92%, χ2=6.12, P=0.013; preparatory assignments, 61.54% vs. 80.77%, χ2=4.68, P=0.030; English literature, 53.85% vs. 75.00%, χ2=5.80, P=0.016; and flipped class lectures, 36.54% vs. 59.62%, χ2=5.55, P=0.019). ③Enhanced competency in ≥2 core areas was reported in 71.68% of students, including theoretical knowledge acquisition (49.71%), self-directed learning (35.84%), clinical thinking (31.21%), research capabilities (25.43%), and communication skills (22.54%). ④Faculty feedback indicated that 83.33% of instructors perceived the flipped classroom as equivalent or superior to traditional teaching, particularly in cultivating clinical thinking (90.48%), self-directed learning (85.71%), theoretical knowledge acquisition (76.19%), and communication skills (76.19%). ⑤Student participation willingness was primarily influenced by pre-class time investment (46.51% reported excessive effort in preparing discussion materials), while faculty engagement depended on implementation effectiveness (42.86%) and curriculum design (35.71%). Conclusions:The flipped classroom method demonstrated promising initial outcomes in pediatric internship, with high satisfaction among both students and faculty. However, further exploration and practice are required in optimizing teaching components, implementing differentiated instructional strategies, and managing time investment.

The "Guidelines for prevention of respiratory syncytial virus (RSV) infection in mothers and infants (2025 Edition)" were developed by the Society of Perinatal Medicine, Chinese Medical Association. This guideline focuses on preventing RSV infections in maternal and neonatal populations, providing 15 evidence-based recommendations addressing eight clinical questions that integrate current best evidence with clinical expertise and patient preferences. The recommendations encompass non-pharmacological prevention, pharmacological prophylaxis, and vaccine strategies. This article provides a comprehensive interpretation of the guidelines, summarizes the current evidence status and practical limitations, and aims to facilitate better understanding and application of the recommendations among healthcare providers, thereby enhancing RSV infection prevention and control for maternal and neonatal populations in China.

Objective:To evaluate the short-term safety of Nirsevimab injection for preventing respiratory syncytial virus infections in infants through a physician-nurse-pharmacist collaborative model.Methods:This prospective observational study enrolled infants receiving single-dose Nirsevimab at Peking University Third Hospital from September 2024 to August 2025. A multidisciplinary team comprising pediatricians, nurses, pharmacists, and obstetricians was established to develop standardized protocols for medication management, injection procedures, follow-up processes, and safety assessment forms. Descriptive statistics analyzed on-site observations within 30 minutes post-injection and all adverse events, with causality assessment conducted.Results:Among 331 participants [171 males (51.7%), 160 females (48.3%)], 225 (68.0%) received outpatient injections and 106 (32.0%) inpatient injections. Successful administration was achieved in 330 cases (99.7%), including 207 (62.7%) receiving 50 mg/vial and 123 (37.3%) receiving 100 mg/vial formulations; one child (3 years 11 months, 19.0 kg) received two 100 mg doses. During the 30-minute observation, 11 cases (3.3%) experienced adverse events, all presenting as injection site erythema following 100 mg/vial administration, with no systemic or serious adverse events observed. All symptoms resolved spontaneously within 30 minutes. Multidisciplinary review suggested potential associations with insufficient rewarming time, larger injection volumes, or post-injection compression pressure.Conclusion:Nirsevimab demonstrated favorable short-term safety profiles in Chinese infants following single-dose administration, with feasible multidisciplinary standardized protocols, though larger sample sizes and extended follow-up are warranted for monitoring medium-to-long-term safety and special populations.

With the efforts of Professor Yan Renying, the "Mother of Chinese Perinatal Health Care", the Society of Perinatal Medicine of Chinese Medical Association was established on April 24,1988. In order to reduce the mortality and disability rate associated with neonatal asphyxia, many efforts have been initiated to promote the "Neonatal Resuscitation Program in China" by the Society of Perinatal Medicine in 2004. This article summarizes the implementation strategy, projects, and achievements of the program, and makes prospects for the future.

Objective:To investigate the risk factors of bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants with gestational age ≤32 weeks within 28 days after birth and to establish and validate the nomogram model for BPD prediction.Methods:We retrospectively chose VLBW infants with gestational age ≤32 weeks who survived to postmenstrual age (PMA) 36 weeks and were admitted to the neonatal intensive care unit of Peking University Third Hospital from January 2016 to April 2020 as the training cohort. BPD was diagnosed in accordance with the 2018 criteria. The clinical data of these infants were collected, and the risk factors of BPD were analyzed by Chi-square test, Mann-Whitney U test, and multivariate logistic regression, and a nomogram model was established. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was used to assess the predictive performance. Decision curve analysis (DCA) was constructed for differentiation evaluation, and the calibration chart and Hosmer-Lemeshow goodness of fit test were used for the calibration evaluation. Bootstrap was used for internal validation. VLBW infants with gestational age ≤32 weeks survived to PMA 36 weeks and admitted to Hebei Chengde Maternal and Child Health Hospital from October 2017 to February 2022 were included as the validation cohort. ROC curve and calibration plot were conducted in the validation cohort for external validation. Results:Of the 467 premature infants included in the training cohort, 104 were in the BPD group; of the 101 patients in the external validation cohort, 16 were in the BPD group. Multivariate logistic regression analysis showed that low birth weight ( OR=0.03, 95% CI: 0.01-0.13), nosocomial pneumonia ( OR=2.40, 95% CI: 1.41-4.09), late-onset sepsis ( OR=2.18, 95% CI: 1.18-4.02), and prolonged duration of endotracheal intubation ( OR=1.61, 95% CI: 1.26-2.04) were risk factors for BPD in these groups of infants (all P<0.05). According to the multivariate logistic regression analysis results, a nomogram model for predicting BPD risk was established. The AUC of the training cohort was 0.827 (95% CI: 0.783-0.872), and the ideal cut-off value for predicted probability was 0.206, with a sensitivity of 0.788 (95% CI: 0.697-0.862) and specificity of 0.744 (95% CI: 0.696-0.788). The AUC of the validation cohort was 0.951 (95% CI:0.904-0.999). Taking the prediction probability of 0.206 as the high-risk threshold, the sensitivity and specificity corresponding to this value were 0.812 (95% CI: 0.537-0.950) and 0.882 (95% CI: 0.790-0.939). The Hosmer-Lemeshow goodness-of-fit test in the training and validation cohort showed a good fit ( P>0.05). DCA results showed a high net benefit of clinical intervention in very preterm infants when the threshold probability was 5%~80% for the training cohort. Conclusion:Low birth weight, nosocomial pneumonia, late-onset sepsis, and prolonged tracheal intubation duration are risk factors for BPD. The established nomogram model has a certain value in predicting the risk of BPD in VLBW less than 32 weeks.
