Faced with an unprecedented amount of data coming from evermore ubiquitous sensors, the wastewater treatment community has been hard at work to develop new monitoring systems, models and controllers to bridge the gap between current practice and data-driven, smart water systems. For additional sensor data and models to have an appreciable impact, however, they must be relevant enough to be looked at by busy water professionals; be clear enough to be understood; be reliable enough to be believed and be convincing enough to be acted upon. Failure to attain any one of those aspects can be a fatal blow to the adoption of even the most promising new measurement technology. This review paper examines the state-of-the-art in the transformation of raw data into actionable insight, specifically for water resource recovery facility (WRRF) operation. Sources of difficulties found along the way are pinpointed, while also exploring possible paths towards improving the value of collected data for all stakeholders, i.e., all personnel that have a stake in the good and efficient operation of a WRRF.

Introduction: The aim of the observational SIMPLE study was to assess real-life effectiveness and safety of a single-pill combination (SPC) of perindopril arginine/amlodipine in a broad range of subjects with newly diagnosed mild-to-moderate hypertension treated in Canadian general practice.

Methods: Treatment-naïve participants aged 18-65 years with mild-to-moderate hypertension, whose physicians decided to initiate the perindopril/amlodipine SPC, were recruited from Canadian clinical practice from October 2017 to February 2019. Participants were followed at 3- (M3) and 6-month (M6) visits after treatment initiation.

Introduction: Chronic obstructive pulmonary disease (COPD) is associated with exacerbations which can reduce quality of life and increase mortality. Single-inhaler triple therapy (SITT) is recommended for maintenance treatment of COPD among patients experiencing exacerbations despite dual-therapy use. This real-world comparative effectiveness study compared the impact of SITTs, fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), and budesonide/glycopyrrolate/formoterol fumarate (BUD/GLY/FORM), on COPD exacerbations and mortality.

Background: Interventricular dyssynchrony derived from the classic non-physiological stimulation (n-PS) of the right ventricle (RV) is a known cause of left ventricular dysfunction (LVDys).

Methods: This was a prospective descriptive single-center study. We analyzed patients who develop LVDys with n-PS, and the results after upgrading to conduction system pacing (CSP).

Background: Reducing inequities in hypertension control among those affected in low- and middle-income countries requires person-centred health system responses based on a contextualised understanding of the choices and care pathways taken by those who rely on the services provided, particularly those from poor and marginalised communities. We examine patterns of care seeking and pathways followed by individuals with hypertension from low-income households in the Philippines and Malaysia. This study aims to fill a significant gap in the literature by analysing the stages at which individuals make decisions that may affect the successful control of their blood pressure.

Purpose: Autistic adults experience high rates of traumatic events and PTSD. However, little work has evaluated motor vehicle accident (MVA) related trauma symptoms. The goal of this brief report was to provide pilot data characterizing MVA-related peritraumatic reactions, trauma symptoms, and rates of PTSD diagnosis and mental health service use among Autistic compared to non-autistic adults.
