RESUMEN
BACKGROUND: The detailed hemodynamics after patent ductus arteriosus (PDA) ligation in preterm infants remain unknown. We aimed to clarify the effect of surgical ligation on left ventricular (LV) and right ventricular (RV) volume and function. METHODS: Echocardiography was performed in 41 preterm infants (median gestational age: 25 weeks) before and after PDA ligation. Global longitudinal strain was determined using three-dimensional speckle-tracking echocardiography. These values were compared with those in 36 preterm infants without PDA (non-PDA). RESULTS: Preoperatively, the PDA group had greater end-diastolic volume (EDV) and cardiac output (CO) in both ventricles, a higher LV ejection fraction (LVEF) (53% vs 44%) and LV global longitudinal strain, and a lower RVEF (47% vs 52%) than the non-PDA group. At 4-8 h postoperatively, the two groups had a similar LVEDV and RVEDV. However, the PDA group had a lower EF and CO in both ventricles than the non-PDA group. At 24-48 h postoperatively, the RVEF was increased, but the LVEF remained decreased, and LVCO was increased. CONCLUSIONS: PDA induces biventricular loading and functional abnormalities in preterm infants, and they dramatically change after surgery. Three-dimensional echocardiography may be beneficial to understand the status of both ventricles. IMPACT: Preterm infants are at high risk of hemodynamic compromise following a sudden change in loading conditions after PDA ligation. Three-dimensional echocardiography enables quantitative and serial evaluation of ventricular function and volume in preterm infants with PDA. PDA induces biventricular loading and functional abnormalities in preterm infants, and they dramatically change after surgery.
RESUMEN
Japan's rapidly aging and high-mortality society necessitates a wider awareness and implementation of advance care planning. This Yamagata Cohort study investigated local residents' preferences for where they would like to spend their final days, and the underlying factors associated with those preferences with a self-administered questionnaire survey of local residents aged 40 years and over . Logistic regression analyses were used to assess those factors and, specifically, the choice of "Home" as the preferred place for end-of-life residence. Among the 10,119 responders, 61% chose their home as the most desirable place to spend their final days. The multiple logistic regression analysis showed that the independent factors associated with the choice of "Home" were: male, older age, not living with someone who needs care, not discussing the end of life, currently happy, struggling to live on current income, not feeling anxious or depressed, and current place of residence the same as their grandparents' birthplace. This suggested that reducing the burden of home care and addressing frequent emotional issues such as happiness and anxiety could increase the number of people choosing "Home". Open-ended comments indicated the importance of getting information and options, and discussing the choice of place for terminal care in light of individual backgrounds including having reservations about family. Support and systems are needed to understand what community residents consider important when deciding where to spend their final days, and to bridge the gap between their desired location and their actual end of life.
RESUMEN
INTRODUCTION: For patients with a congenital diaphragmatic hernia, conventional mechanical ventilation (CMV) and high-frequency oscillatory ventilation (HFOV) are used in initial ventilatory management. HFOV has recently been recommended as a rescue therapy; however, we use HFOV for initial ventilation management, with a preoperative challenge test for CMV conversion and respiratory function testing at the time of CMV conversion. We aimed to compare patient characteristics between CMV conversion- and HFOV-preferred treatment groups. METHODS: Ventilator settings and blood gases were retrospectively evaluated pre- and post-CMV conversion, and respiratory function tests for compliance of the respiratory system (Crs) and for resistance of the respiratory system (Rrs) were performed during the trial to CMV conversion. RESULTS: No differences were observed between the CMV conversion- and HFOV-preferred groups regarding gestational age, birth weight, and observed/expected lung area-to-head circumference ratios. The median Crs (ml/cmH2 O/kg) and Rrs (cmH2 Oï½¥kg/L/s) in the CMV conversion- and HFOV-preferred groups was 0.42 versus 0.53 (p = .44) and 467 versus 327 (p = .045), respectively. The pre and posttrial amount of change in blood gas levels and ventilator parameters in the CMV conversion- and HFOV-preferred groups were as follows: mean airway pressure, -2.0 versus 0 cmH2 O; partial pressure of carbon dioxide, 6.1 versus 2.9 Torr; alveolar-arterial oxygen difference, -39.5 versus -50 Torr; and oxygenation index, -1.0 versus -0.6; respectively. CONCLUSION: Respiratory function tests were useful in tailoring ventilator settings. Patients with high Rrs values responded better to CMV conversion.

Objective: We implemented an online visitation system named "telepresence" in the neonatal intensive care unit (NICU) for family members at home to communicate with their babies in real-time using video and audio. This study evaluated the impact of this system on families and medical staff. Methods: Nineteen families of babies admitted to the NICU between 2022 and 2023 and 65 medical staff participated. Each family experienced two weeks of virtual visits. Changes in parental depression and attachment were assessed. Result: Before and after telepresence, the median Edinburgh Postnatal Depression Scale score reduced from 6 to 4 (p = 0.026), and the Mother-to-Infant Bonding Scale score showed a decreasing trend, with both medians at 2 (p = 0.057). Eighty-nine percent of the parents and 97% of staff reported that telepresence did not increase parental stress, and 88% of parents felt positive changes in their baby's siblings. All parents wanted to visit their babies in person after seeing them on camera. Conclusion: Telepresence improved parental mental health, reduced family distress, and supported connection with their infants, making them eager to visit in person. Innovations: This technology potentially make parents want to visit more by helping them feel more connected to their infants.
