A biochar selection method for remediating heavy metal contaminated mine tailings.

Approximately 390,000 abandoned mines across the US pose considerable, pervasive risks to human and environmental health; world-wide the problem is even greater. Lime, organic materials, and other amendments have been used to decrease metal bioavailability (e.g.

Barriers and facilitators for cardiopulmonary resuscitation discussions with people with heart failure.

Background: Care planning with people with advanced heart failure enables appropriate care, and prevents futile interventions, such as cardio-pulmonary resuscitation (CPR).

Aim: To explore what motivates clinicians to conduct, and people with heart failure and their carers, to engage in well-conducted CPR discussions.

Methods: In-depth remote interviews with i) people with heart failure and self-reported daily symptoms (≥ 3 months), ii) informal carers and, iii) clinicians recruited through social media and professional groups, team contacts and snowballing.

Ecology of endolithic bryozoans: colony development, growth rates and interactions of species in the genus Immergentia.

Boring bryozoans dissolve calcium carbonate substrates, leaving unique borehole traces. Depending on the shell type, borehole apertures and colony morphology can be diagnostic for distinguishing taxa, but to discriminate among species their combination with zooidal morphology is essential. All boring (endolithic) bryozoans are ctenostomes that, along with other boring taxa, are common in benthic communities.

Exploring a Novel Outcome Measure of Symptom Progression in Knee Osteoarthritis Utilizing a Large Randomized Trial.

Objectives: Explore a newly defined composite measure of symptom progression for knee osteoarthritis (KOA) in a large, randomized study of a potential disease-modifying osteoarthritis drug (DMOAD).

Design: Using longitudinal KOA studies, a potential composite endpoint of time to symptom progression was defined as the first occurrence of worsening of WOMAC Pain of ≥10 points with no improvement (≤9 point decrease) in WOMAC Function (0-100 scale). A post hoc analysis explored discrimination and association with structural outcomes in the sprifermin FORWARD trial through Years 3 and 5.

Implantable cardioverter defibrillator deactivation and end-of-life: British Heart Rhythm Society practical consensus guideline.

Implantable cardioverter defibrillators (ICDs) are implanted in increasing numbers of patients with the aim of treating ventricular arrhythmias in high-risk patients and reducing their risk of dying. Individuals are also living longer with these devices. As a result, a greater number of patients with an ICD will deteriorate either with worsening cardiac failure, another non-cardiac condition or general frailty and will have a limited prognosis.
