The subsystem Nurse's A-phase-silicocarnotite within the system Ca₃(PO₄)₂-Ca₂SiO₄ was conducted as a preliminary step toward obtaining new biomaterials with controlled microstructures. Phase composition of the resulting ceramics was studied by X-ray diffraction, differential thermal analysis, and scanning electron microscopy with attached wavelength dispersive spectroscopy. The results showed that the sub-system presents an invariant eutectoid point at 1366 ± 4 °C with a composition of 59.5 wt % Ca₃(PO₄)₂ and 40.5 wt % Ca₂SiO₄, and typical eutectoid microstructure of lamellae morphology. These results are in disagreement with the previous reported data, which locate the invariant eutectoid point at 1250 ± 20 °C with a composition of 55 wt % Ca₃(PO₄)₂ and 45 wt % Ca₂SiO₄. In addition, cell attachment testing showed that the new eutectoid material supported the mesenchymal stem cell adhesion and spreading, and the cells established close contact with the ceramic after 28 days of culture. These findings indicate that the new ceramic material with eutectoid microstructure of lamellae morphology possesses good bioactivity and biocompatibility and might be a promising bone implant material.

Background: Nurses constitute the largest number of hospital information system (HIS) users. Therefore, their awareness level and access to HIS functions based on their needs are particularly important. The present study aims to determine nurses' access levels to HIS functions and examine the compliance between defined and required access levels to core functionalities of a comprehensive HIS.

Introduction: Nursing-sensitive indicators measure and evaluate nursing care quality and its contribution to patient care. The identification of indicators that demonstrate nursing care contribution and the quality of care delivered locally is of paramount importance, and national indicators that demonstrate this are essential. This paper aims to provide an evidence base of nursing-sensitive indicators that can facilitate the conceptualization of local nursing national indicators.

Background: Surgical scheduling is pivotal in managing daily surgical sequences, impacting patient experience and hospital resources significantly. With operating rooms costing approximately US $36 per minute, efficient scheduling is vital. However, global practices in surgical scheduling vary, largely due to challenges in predicting individual surgeon times for diverse patient conditions.

Objective: To assess the role of nurse-guided maternal interventional package for reducing stress behaviour among preterm neonates admitted in neonatal intensive care unit (NICU).
Methods: A randomized controlled trial was conducted among 100 mothers and their newborns delivered preterm and admitted consecutively in the NICU over 4 months. Mothers in the intervention group (n = 50) received education and demonstration regarding the use of maternal touch, facilitated tucking, kangaroo mother care (KMC), non-nutritive sucking (NNS), nesting and maternal voice alongwith a handout in local language for five consecutive days, while those in the control group (n = 50) received routine care including KMC and NNS for five consecutive days.
