An adaptive Kalman filter-based fusion algorithm capable of estimating respiration rate for unobtrusive respiratory monitoring is proposed. Using both signal characteristics and a priori information, the Kalman filter is adaptively optimized to improve accuracy. Furthermore, the system is able to combine the respiration-related signals extracted from a textile ECG sensor and an accelerometer to create a single robust measurement. We measured derived respiratory rates and, when compared to a reference, found root-mean-square error of 2.11 breaths-per-minute (BrPM) while lying down, 2.30 BrPM while sitting, 5.97 BrPM while walking, and 5.98 BrPM while running. These results demonstrate that the proposed system is applicable to unobtrusive monitoring for various applications.

Background: Ureaplasma urealyticum, Ureaplasma parvum, and Mycoplasma hominis were widely known as ammonia-producing microorganisms and can cause hyperammonemia, leading to cerebral edema and altered consciousness, which represent serious complications in lung transplant recipients. However, there is limited knowledge on the epidemiology and outcomes of infections caused by U. urealyticum, U.

Objective: To investigate the incidence and survival rates of paediatric patients receiving resuscitation for in-hospital cardiac arrest (IHCA) in a teaching hospital in Northern Jordan, comparing initial pulseless rhythms and bradycardia rhythm with poor perfusion.
Design: Retrospective observational study SETTING: An university-affiliated tertiary hospital in Northern Jordan, covering January 2015 to December 2022.
Patients: All hospitalised paediatric patients aged 1 month-18 years who received cardiopulmonary resuscitation (CPR) for cardiac arrest were included in the study.
Derivation and validation of the simplified BleedingAudit Triage Trauma (sBATT) score: a simplified trauma score for major trauma patients injured in motor vehicle collisions.

Emergency Department, Lausanne University Hospital, Lausanne, Switzerland.
Objectives: To develop and validate a simplified Bleeding Audit Triage Trauma (sBATT) score for use by lay persons, or in areas and environments where physiological monitoring equipment may be unavailable or inappropriate.
Design: The sBATT was derived from the original BATT, which included prehospital systolic blood pressure (SBP), heart rate, respiratory rate, Glasgow Coma Scale (GCS), age and trauma mechanism. Variables suitable for lay interpretation without monitoring equipment were included (age, level of consciousness, absence of radial pulse, tachycardia and trapped status).

Objectives: To study the treatment outcomes of extremely preterm infants.
Methods: A retrospective analysis was performed for the clinical data of extremely preterm infants who were admitted to the neonatal intensive care unit of the Third Affiliated Hospital of Zhengzhou University from January 2016 to December 2022. The infants were divided into a non-in-hospital death group and a survival group.

Objectives: To explore the epidemiological characteristics of respiratory syncytial virus (RSV) infection in children in Nanchang and its correlation with climate environmental factors.
Methods: The clinical data were collected from children with acute respiratory infection in Nanchang who were tested for RSV at Jiangxi Provincial Children's Hospital from January 2019 to December 2023, along with climate environmental data for the same period. The epidemiological characteristics of RSV and their correlation with climate environmental factors were investigated.
