A systematic review to determine the effect of strategies to sustain chronic disease prevention interventions in clinical and community settings.

This review assessed the effect of strategies designed to sustain the delivery of evidenced based interventions (EBIs) which target behavioural risk factors linked to leading causes of chronic disease in clinical and community settings. Seven electronic databases were searched for randomised controlled studies published from earliest record to November 2022. Studies were included if they tested a strategy to sustain the delivery of an EBI within clinical or community settings.

Correlates and Predictors of Symptom Severity Over Time in People Under Investigation for Postural Orthostatic Tachycardia Syndrome.

Objective: Postural orthostatic tachycardia syndrome (POTS) is a poorly understood chronic disorder characterized by an unexplained excessive increase in heartbeat upon standing. The aim of this study was to investigate psychosocial and physiological correlates and predictors of symptom severity over time in patients presenting with POTS-like symptoms.

Methods: Longitudinal cohort study of patients under investigation for POTS ( n = 149).

Validation of symptom measures in patients under investigation for postural orthostatic tachycardia syndrome (POTS): The Orthostatic Grading Scale (OGS) and the Symptom Screen for Small-fiber Polyneuropathy (SSS).

Objectives: Postural Orthostatic Tachycardia Syndrome (POTS) presents with a range of poorly delineated symptoms across several domains. There is an urgent need for standardized symptom reporting in POTS, but a lack of validated symptom burden instruments. Our aim was to evaluate the psychometric properties of two symptom burden measures: the Orthostatic Grading Scale (OGS) and the Symptom Screen for Small-Fiber Polyneuropathy (SSS), in patients under investigation for suspected POTS.

A cluster randomised controlled trial to assess the effectiveness of a multi-strategy sustainability intervention on teachers' sustained implementation of classroom physical activity breaks (energisers): study protocol.

Background: Governments internationally have invested hugely in the implementation and scale-up of school-based physical activity interventions, but have little evidence of how to best sustain these interventions once active implementation support ceases. This study will assess the effectiveness of a multi-strategy sustainability intervention on classroom teachers' sustainment of energisers (short 3-5 min physical activity breaks during class-time) scheduled across the school day from baseline to 12 and 24-month follow-up.

Methods: A cluster randomised controlled trial will be conducted in 50 primary schools within the Hunter New England, Illawarra Shoalhaven, Murrumbidgee and Northern New South Wales (NSW) Local Health Districts of NSW Australia.
