At present, there is no clear and universal definition of polypharmacy. This review summarises the most common definitions and discusses the challenges in finding one suitable definition. Most of the literature has defined polypharmacy as the simultaneous use of five or more drugs.

Minor tranquillizers for short-term treatment of newly onset symptoms of anxiety and distress: a systematic review with network meta-analysis of randomized trials.

Unspecific symptoms of anxiety and distress are frequently encountered in patients in both general practice and acute psychiatric services. Minor tranquillizers may be a treatment option when non-pharmacological interventions are insufficient or unavailable. We conducted a systematic review with network meta-analysis of the evidence for short-term (1-4 weeks) pharmacological treatment of newly onset symptoms of anxiety and distress.

Involving frail older patients in identifying outcome measures for transitional care-a feasibility study.

Background: During care transitions, the older (75+) patient's agenda can easily be missed. To counteract this, involving patients in shared clinical decision making has proven to be of great value. Likewise, involving patients and other stakeholders as researchers is gaining ground.

Flow-induced [Ca2+]i increase depends on nucleotide release and subsequent purinergic signaling in the intact nephron.

Flow induces cytosolic Ca(2+) increases ([Ca(2+)](i)) in intact renal tubules, but the mechanism is elusive. Mechanical stimulation in general is known to promote release of nucleotides (ATP/UTP) and trigger auto- and paracrine activation of P2 receptors in renal epithelia. It was hypothesized that the flow-induced [Ca(2+)](i) response in the renal tubule involves mechanically stimulated nucleotide release.
