Background: Oscillometric pressure is measured by analysing, in relation to the cuff pressure, low-amplitude cuff-pressure pulsations generated by each arterial pulse. The cuff pressure is sampled at the pulse rate, introducing measurement variations, which are compounded by artefactual pulses.
Objective: To study the consistency of measurements with and without artefacts using simulated waveforms.
Methods: The Propaq Smartcuf (with and without electrocardiographic synchronization), the Welch Allyn 52 000 (before and after its software had been upgraded), the Critikon DINAMAP 8100 and Compact TS and the Criticare 507 NJC were evaluated. Each monitor recorded 15 determinations at 120/80 (93) mmHg without and with either low-frequency or high-frequency artefacts generated by the Bio-Tek BP-Pump simulator. Consistency of measurements was defined as SD of less than 2 mmHg for at least two of the systolic, diastolic and mean arterial pressures with all less than 3 mmHg.
Results: All monitors except the Critikon 8100 satisfied the consistency criteria without artefacts with most SD less than 1 mmHg. Several satisfied the criteria with a severe low-frequency artefact (all recorded SD were less than 6 mmHg). None satisfied the criteria with a severe high-frequency artefact. High systolic blood pressures were typically recorded with a severe tremor artefact, though the Criticare device, which measures during cuff inflation, recorded lower systolic blood pressures. The Propaq device with electrocardiographic synchronization had the lowest variability, with synchronization increasing determination time.
Conclusion: Oscillometric monitors are more sensitive to a high-frequency artefact than they are to a low-frequency artefact. Signal-processing techniques can improve consistency of measurements. Simulators can evaluate a monitor's consistency with and without artefacts.

Background: Wearable sensor technologies, often referred to as "wearables," have seen a rapid rise in consumer interest in recent years. Initially often seen as "activity trackers," wearables have gradually expanded to also estimate sleep, stress, and physiological recovery. In occupational settings, there is a growing interest in applying this technology to promote health and well-being, especially in professions with highly demanding working conditions such as first responders.

Background: Patients with Gaucher disease (GD) require continual monitoring; however, lack of specific disease biomarkers was a significant challenge in the past. Glucosylsphingosine (lyso-Gb1) has been shown to be a reliable, key, specific, and sensitive biomarker for diagnosis, prognosis, and treatment response in clinical studies of patients with GD. We evaluated the change in lyso-Gb1 concentration over time following enzyme replacement therapy in patients with confirmed GD using real-world data from the Gaucher Outcome Survey disease registry.

Background: Comprehensive clinical data regarding factors influencing the individual disease course of patients with movement disorders treated with deep brain stimulation might help to better understand disease progression and to develop individualized treatment approaches.
Methods: The clinical core data set was developed by a multidisciplinary working group within the German transregional collaborative research network ReTune. The development followed standardized methodology comprising review of available evidence, a consensus process and performance of the first phase of the study.

Background: There is a paucity of brief self-report parenting measures validated for use in low- and middle-income countries (LMICs). We developed the Brief Parenting Questionnaire (BPQ), a 24-item self-report measure for use with parents of children ages 3-12.
Objective: We describe the development and evaluation of the psychometric properties of the BPQ, which was designed to include two subscales: warm and responsive parenting (WRP) and harsh parenting (HP).

Objective: Life interference is a key diagnostic feature for anxiety and depressive disorders. Measures focusing on life interference caused by anxiety and depressive disorders in children and adolescents have received minimal attention. This study evaluated the psychometric properties of the Child Anxiety and Depression Life Interference Scale (CADLIS), a brief child (CADLIS-C) and parent-report (CADLIS-P) measure designed to assess life interference from anxiety and depressive disorders in both the child and parent's life.
