Background: The objective of this study was to evaluate the levels of Vascular Peroxidase 1 (VPO1), humanin, and MOTS-c in relation to miR-200c expression in untreated preeclamptic pregnancies, and to compare these findings with endoglin levels.

Methods And Results: In this study, blood samples were collected from preeclamptic patients presenting to the clinic prior to the initiation of treatment. The levels of endoglin, VPO1, humanin, and MOTS-c were measured using enzyme-linked immunosorbent assay (ELISA), while miR-200c expression was quantified using reverse transcription polymerase chain reaction (RT-PCR).

Background: Hereditary hypophosphatemia (HH), is a rare condition related to decreased renal tubular phosphate reabsorption. Although X-linked hypophosphatemia or PHEX gene variant is the most frequent cause of HH, recent advances in next-generation sequencing (NGS) techniques enable the identification of genetic etiologies as a whole.

Objective: To identify genetic causes of HH using various genetic testing methods and to compare clinical features between FGF23-dependent and FGF23-independent HH groups.

Background: This study investigates the effects of lean management practices on nurses' direct patient care activities and the interruptions they encounter in healthcare settings. The literature indicates that lean management enhances efficiency and improves patient care. Increased nursing time per patient correlates with better outcomes; however, rising patient loads and frequent interruptions hinder nurses' ability to deliver effective care, jeopardising patient safety.

Background: Recurrent infections of the nose, sinuses and ears are common problems for people with primary ciliary dyskinesia. While pulmonary exacerbations in primary ciliary dyskinesia are defined, there is no definition for ear-nose-throat exacerbations, a potential outcome for research and clinical trials.

Methods: We set up an expert panel of 24 ear-nose-throat specialists, respiratory physicians, other healthcare professionals and patients to develop consensus definitions of sinonasal and otological exacerbations in children and adults with primary ciliary dyskinesia for research settings.

Unmanned Aerial Vehicles (UAVs) have become essential tools across various sectors due to their versatility and advanced capabilities in autonomy, perception, and networking. Despite over a decade of experimental efforts in multi-UAV systems, substantial theoretical challenges concerning coordination mechanisms still need to be solved, particularly in maintaining network connectivity and optimizing routing. Current research has revealed the absence of an efficient algorithm tailored for the routing problem of multiple UAVs connected to a central station, especially under the constraints of maintaining constant network connectivity and minimizing the average goal revisit time.
