Effectiveness of Human-Supported and Self-Help eHealth Lifestyle Interventions for Patients With Cardiometabolic Risk Factors:: A Meta-Analysis

Objective eHealth is a useful tool to deliver lifestyle interventions for patients with cardiometabolic diseases. However, there are inconsistent findings about whether these eHealth interventions should be supported by a human professional, or whether self-help interventions are equally effective. Methods Databases were searched between...

eHealth to Improve Psychological Functioning and Self-Management of People With Chronic Kidney Disease: A Randomized Controlled Trial

Objective Psychological distress is common among patients with chronic kidney disease and can interfere with disease self-management. We assessed the effectiveness of the personalized E-GOAL electronic health care pathway with screening and cognitive-behavioral therapy including self-management support, aimed to treat psychological distress...

Susceptibility to Nocebo Hyperalgesia, Dispositional Optimism, and Trait Anxiety as Predictors of Nocebo Hyperalgesia Reduction

OBJECTIVES: The current paper explores the psychological predictors of nocebo hyperalgesia and whether the reduction of nocebo hyperalgesia can be predicted by susceptibility to nocebo hyperalgesia and psychological characteristics. METHODS: Nocebo effects on pressure pain were first experimentally induced in 83 healthy female participants...

Foulant Identification and Performance Evaluation of Antiscalants in Increasing the Recovery of a Reverse Osmosis System Treating Anaerobic Groundwater

The objectives of this study are to assess the performance of antiscalants in increasing the recovery (≥85%) of a reverse osmosis (RO) plant treating anaerobic groundwater (GW) in Kamerik (the Netherlands), and to identify scalants/foulant that may limit RO recovery. Five different commercially available antiscalants were compared on the...

Application of a smart dosing pump algorithm in identifying real-time optimum dose of antiscalant in reverse osmosis systems

The potential of membrane scaling control by a real-time optimization algorithm was investigated. The effect of antiscalant dosing was evaluated from the induction time measured in glass batch-reactors, and from the operational performance of a lab-scale reverse osmosis (RO) unit and two pilot-scale RO units. Step changes in the antiscalant...

Comparing the bacterial growth potential of ultra-low nutrient drinking water assessed by growth tests based on flow cytometric intact cell count versus adenosine triphosphate

The bacterial growth potential (BGP) of drinking water is widely assessed either by flow cytometric intact cell count (BGP_ICC) or adenosine triphosphate (BGP_ATP) based methods. Combining BGP_ICC and BGP_ATP measurements has been previously applied for various types of drinking water having high to low...

Effectiveness of antiscalants in preventing calcium phosphate scaling in reverse osmosis applications

Antiscalants are well known to prevent the precipitation of carbonate and sulphate scales of calcium in reverse osmosis (RO) applications, but according to literature their inhibitory ability against calcium phosphate is not clear. The objective of this study was to investigate if antiscalants, without acid addition, can prevent calcium...

Berkenpek uit de Noordzee: Een zeldzame vondst werpt licht op het gedrag van neanderthalers

In 2016 raapte amateurarcheologe en -paleontologe Willy van Wingerden uit Honselersdijk op het strand bij Kijkduin een klein stukje vuursteen op met aan één kant een aangehechte zwarte materie. Ze liet de vondst enkele dagen later aan archeoloog Marcel Niekus zien. Die werd direct enthousiast, het zwarte goedje zou wel eens berkenpek kunnen zijn...

Multi-parametric assessment of biological stability of drinking water produced from groundwater: Reverse osmosis vs. conventional treatment

Although water produced by reverse osmosis (RO) filtration has low bacterial growth potential (BGP), post-treatment of RO permeate, which is necessary prior to distribution and human consumption, needs to be examined because of the potential re-introduction of nutrients/contaminants. In this study, drinking water produced from anaerobic...
