Acute remote home monitoring of acutely ill patients with COVID-19: how Dutch home monitoring initiatives were organized during the pandemic.

Background: Acute remote home monitoring of acutely ill patients with COVID-19 holds potential for early detection of deterioration and thus subsequentearly intervention that may prevent or mitigate progression to severe illness and need for respiratory support. Our aim was to describe common features of acute remote home monitoring programs for acutely ill patients with COVID-19 in the Netherlands.

Methods: We performed literature searches (both grey and academic) between 1st March 2020 and 1st March 2023 to identify Dutch acute remote home monitoring initiatives, excluding studies on early hospital discharge.

Implementation of a tailored multifaceted antibiotic stewardship intervention to improve antibiotic prescribing for urinary tract infections in frail older adults (ImpresU) in four European countries: a process evaluation alongside a pragmatic cluster randomized controlled trial.

Background: We previously performed a pragmatic cluster randomized controlled trial (RCT) in general practices and older adult care organizations in Poland, the Netherlands, Norway, and Sweden. We found that a multifaceted antibiotic stewardship intervention (ASI) substantially reduced antibiotic use for suspected urinary tract infections (UTIs) in frail older adults compared with usual care. We aimed to evaluate the implementation process of the ASI to provide recommendations for clinical practice.

Organismal metabolism regulates the expansion of oncogenic PIK3CA mutant clones in normal esophagus.

Oncogenic PIK3CA mutations generate large clones in aging human esophagus. Here we investigate the behavior of Pik3ca mutant clones in the normal esophageal epithelium of transgenic mice. Expression of a heterozygous Pik3ca mutation drives clonal expansion by tilting cell fate toward proliferation.

Spatial regulation of substrate adhesion directs fibroblast morphotype and phenotype.

The switching of the fibroblast phenotype to myofibroblast is a hallmark of a wide variety of tissue pathologies. This phenotypical switch is known to be influenced not only by humoral factors such as TGF-β, but also by mechanical and physical cues in the cellular environment, and is accompanied by distinctive changes in cell morphology. However, the causative link between these cues, the concomitant morphological changes, and the resulting phenotypic switch remain elusive.

GelMA hydrogel dual photo-crosslinking to dynamically modulate ECM stiffness.

The dynamic nature of the extracellular matrix (ECM), particularly its stiffness, plays a pivotal role in cellular behavior, especially after myocardial infarction (MI), where cardiac fibroblasts (cFbs) are key in ECM remodeling. This study explores the effects of dynamic stiffness changes on cFb activation and ECM production, addressing a gap in understanding the dynamics of ECM stiffness and their impact on cellular behavior. Utilizing gelatin methacrylate (GelMA) hydrogels, we developed a model to dynamically alter the stiffness of cFb environment through a two-step photocrosslinking process.
