A descriptive analysis of drug-drug interactions and corresponding adverse drug reactions in multimorbid older inpatients: findings from the SENATOR trial.

Purpose: Drug-drug interactions (DDIs) are prevalent among multimorbid and polymedicated older adults and can increase the risk of adverse drug reactions (ADRs), hospital admissions, and mortality. This study describes the incidence and prevalence of 66 clinically relevant DDIs and analyses the occurrence of 12 corresponding predefined ADRs in older inpatients enrolled in the SENATOR trial.

Methods: The sub-study of the SENATOR trial that involved 1537 multimorbid older inpatients, recruited from 2016 to 2018 in six academic teaching hospitals in Belgium, Iceland, Ireland, Italy, Scotland, and Spain respectively, and analysed 66 potentially clinically significant DDIs.

Corrosion Inhibition of Mild Steel by Coumarate-Based Ionic Liquids and Coatings.

The use of ionic liquids (ILs) as corrosion inhibitors is gaining significant attention due to their attractive properties such as high inhibition efficiency and ability to absorb onto metal surfaces. In this work, six protic ILs, based on the coumarate anion in combination with the nitrogen containing ammonium, pyrrolidinium and imidazolium cations with a short or long alkyl chain attached to the nitrogen atom, have been synthesized and evaluated as corrosion inhibitors for mild steel. The anticorrosion properties of these ILs in solution as inhibitors were investigated electrochemically and the metal surface was analyzed by Scanning Electron Microscopy.

The synergistic effects of mechanical ventilation and intrauterine inflammation on cerebral inflammation in preterm fetal sheep.

Background: Intrauterine inflammation and the requirement for mechanical ventilation independently increase the risk of perinatal brain injury and adverse neurodevelopmental outcomes. We aimed to investigate the effects of mechanical ventilation for 24 h, with and without prior exposure to intrauterine inflammation, on markers of brain inflammation and injury in the preterm sheep brain.

Methods: Chronically instrumented fetal sheep at ~115 days of gestation were randomly allocated to receive a single intratracheal dose of 1 mg lipopolysaccharide (LPS) or isovolumetric saline, then further randomly allocated 1 h after to receive mechanical ventilation with room air or no mechanical ventilation (unventilated control + saline [UVC,  = 7]; mechanical ventilation + saline [VENT,  = 8], unventilated control + intratracheal LPS [UVC + LPS,  = 7]; ventilation + intratracheal LPS [VENT + LPS,  = 7]).

Optimizing anticoagulation therapy for in-hospital patients on direct oral anticoagulants: a single-centre modified Delphi study.

Aims: The management of patients treated with direct oral anticoagulants (DOACs) during hospitalization is a common challenge in clinical practice. Although bridging is generally not recommended, too often DOACs are switched to parenteral therapy with low molecular weight heparins. Our objectives were to update a local guideline for perioperative DOAC management and to develop a guideline for the anticoagulation management in non-surgical patients regarding temporary DOAC discontinuation.

Healthcare workers' perspectives on a prescription phone program to meet the health equity needs of patients in the emergency department: a qualitative study.

Objectives: People experiencing homelessness and marginalization face considerable barriers to accessing healthcare services. Increased reliance on technology within healthcare has exacerbated these inequities. We evaluated a hospital-based prescription phone program aimed to reduce digital health inequities and improve access to services among marginalized patients in Emergency Departments.

Pharmaceutical company funding of cancer patient advocacy organizations in the Netherlands.

Background: Financial conflicts of interest (FCOI) of medical professionals and associated organizations with pharmaceutical companies (pharma) might contribute to the use of low value oncological treatments. Value criteria for oncological drug approvals in the Netherlands have recently become more stringent leading to objections by cancer patient advocacy organizations (cPAOs). Considering the importance of cPAOs input in cancer patient care we analyzed whether pharma funding of cPAOs occurs in the Netherlands.

The tool comprises items assessing burden of disease and lifestyle parameters.

The communication GAP between patients and clinicians and the importance of patient reported outcomes in Systemic Lupus Erythematosus.

Systemic Lupus Erythematosus (SLE) imposes a great burden on the lives of patients. Patients' and physicians' concerns about the disease diverge considerably. Physicians focus on controlling disease activity to prevent damage accrual, while patients focus on symptoms that impact on Health-Related Quality of Life (HRQoL).

Impact of model-informed precision dosing in adults receiving vancomycin via continuous infusion: a randomized, controlled clinical trial.

Background: Vancomycin is a commonly prescribed antibiotic to treat gram-positive infections. The efficacy of vancomycin is known to be directly related to the pharmacokinetic/pharmacodynamic (PK/PD) index of the area under the concentration-time curve (AUC) divided by the minimal inhibitory concentration (MIC) of the pathogen. However, in most countries, steady-state plasma concentrations are used as a surrogate parameter of target AUC/MIC, but this practice has some drawbacks.

In utero ventilation induces lung parenchymal and vascular alterations in extremely preterm fetal sheep.

Extremely preterm infants are often exposed to long durations of mechanical ventilation to facilitate gas exchange, resulting in ventilation-induced lung injury (VILI). New lung protective strategies utilizing noninvasive ventilation or low tidal volumes are now common but have not reduced rates of bronchopulmonary dysplasia. We aimed to determine the effect of 24 h of low tidal volume ventilation on the immature lung by ventilating preterm fetal sheep in utero.

Mechanical ventilation induces brainstem inflammation in preterm fetal sheep.

Background: Preterm infants have immature respiratory drive and often require prolonged periods of mechanical ventilation. Prolonged mechanical ventilation induces systemic inflammation resulting in ventilation-induced brain injury, however its effect on brainstem respiratory centers is unknown. We aimed to determine the effects of 24 h of mechanical ventilation on inflammation and injury in brainstem respiratory centres of preterm fetal sheep.

Lignin-Derivative Ionic Liquids as Corrosion Inhibitors.

Corrosion is a significant problem that negatively affects a wide range of structures and buildings, resulting in their premature failure, which causes safety hazards and significant economic loss. For this reason, various approaches have been developed to prevent or minimize the effects of corrosion, including corrosion inhibitors. Recently, biobased inhibitors have gained a certain interest thanks to their unique properties, eco-friendliness, and availability.

Clinical approach to the older person with anorexia.

Objective: Anorexia is a challenging problem among older people. Apart from being the consequence of normal ageing, it can also be a symptom of underlying disease. Despite the high prevalence of anorexia, only few recommendations exist on the evaluation in older people.

Effect of cetrimonium carrier micelles on bacterial membranes and extracellular DNA, an in silico study.

Microorganisms do not live as dispersed single cells but rather they form aggregates with extracellular polymeric substances at interfaces. Biofilms are considered efficient life forms because they shield bacteria from biocides and collect dilute nutrients. This is a big concern in industry since the microorganisms can colonize a wide range of surfaces, accelerating material deterioration, colonizing medical devices, contaminating ultrapure drinking water, increasing energy costs and creating focus of infection.

Tris(dialkylamino)cyclopropenium dialkylphosphate ionic liquids as lubricants.

Six new tris(dialkylamino)cyclopropenium dialkylphosphate ionic liquids (ILs), [C(NR)]BEHP (NR = NEt, NBuMe, NPr, NBu, NHex, NDec; BEHP = bis(2-ethylhexyl)phosphate), were prepared and characterised as potential lubricants. Thermophysical and thermochemical properties of these ILs were investigated, namely: viscosity, density, conductivity, miscibility, thermal stability and phase transitions. Miscibility studies indicated that [C(NEt)]BEHP would not be suitable due to its water solubility and hexane immiscibility.

Therapeutic dilemmas with benzodiazepines and Z-drugs: insomnia and anxiety disorders versus increased fall risk: a clinical review.

Methods: We conducted a literature search in June 2021 in PubMed and Embase with citation and reference checking. Personal reference libraries and international websites were also used.

RE 3-Furoate Complexes: Synthesis, Structure, and Corrosion Inhibiting Properties.

In this study, two types of Rare Earth (RE) 3-furoate complexes were synthesized by metathesis reactions between RE chlorides or nitrates and preformed sodium 3-furoate. Two different structural motifs were identified as Type and Type . The Type monometallic complexes form 2D polymeric networks with the composition [RE(3fur)(HO)] ( = 1La, 1Ce, 1Pr, 1Nd, 1Gd, 1Dy, 1Ho, 1Y; 3furH = 3-furoic acid) while Type bimetallic complexes form 3D polymeric systems [NaRE(3fur)] ( = 2Ho, 2Y, 2Er, 2Yb, 2Lu).

Extracellular DNA: A Critical Aspect of Marine Biofilms.

Multispecies biofilms represent a pervasive threat to marine-based industry, resulting in USD billions in annual losses through biofouling and microbiologically influenced corrosion (MIC). Biocides, the primary line of defence against marine biofilms, now face efficacy and toxicity challenges as chemical tolerance by microorganisms increases. A lack of fundamental understanding of species and EPS composition in marine biofilms remains a bottleneck for the development of effective, target-specific biocides with lower environmental impact.

Enhancing Biocide Efficacy: Targeting Extracellular DNA for Marine Biofilm Disruption.

Biofilm formation is a global health, safety and economic concern. The extracellular composition of deleterious multispecies biofilms remains uncanvassed, leading to an absence of targeted biofilm mitigation strategies. Besides economic incentives, drive also exists from industry and research to develop and apply environmentally sustainable chemical treatments (biocides); especially in engineered systems associated with the marine environment.

Development and content validation of the Assessment of Burden of ColoRectal Cancer (ABCRC)-tool.

Background: It is essential to include patient-reported outcomes (PROs), such as health-related quality of life and symptom burden, in follow-up care of colorectal cancer (CRC) survivors. These outcomes are most valuable when they are discussed with patients and used to guide follow-up care. The purpose of this study was to develop and validate the Assessment of Burden of Colorectal cancer (ABCRC)-tool: a tool that includes a patient-reported questionnaire covering the experienced burden of colorectal cancer, assessment of lifestyle parameters, visualisation of the results, and treatment advice.

Conditioning of metal surfaces enhances adhesion.

Microbiologically influenced corrosion and biofouling of steels depend on the adsorption of a conditioning film and subsequent attachment of bacteria. Extracellular deoxyribonucleic acid (eDNA) and amino acids are biologically critical nutrient sources and are ubiquitous in marine environments. However, little is known about their role as conditioning film molecules in early biofilm formation on metallic surfaces.

Model-informed precision dosing of vancomycin via continuous infusion: a clinical fit-for-purpose evaluation of published PK models.

Background: Model-informed precision dosing is an innovative approach used to guide bedside vancomycin dosing. The use of Bayesian software requires suitable and externally validated population pharmacokinetic (popPK) models.

Objectives: This study aimed to identify suitable popPK models for a priori prediction and a posteriori forecasting of vancomycin in continuous infusion.

Rapid deployment of a virtual simulation curriculum to prepare for critical care triage during the COVID-19 pandemic.

Background: During the COVID-19 pandemic in Ontario, Canada, an Emergency Standard of Care for Major Surge was created to establish a uniform process for the "triage" of finite critical care resources. This proposed departure from usual clinical care highlighted the need for an educational tool to prepare physicians for making and communicating difficult triage decisions. We created a just-in-time, virtual, simulation-based curriculum and evaluated its impact for our group of academic Emergency Physicians.
