Test-Retest Reliability of Measuring the Vertebral Arterial Blood Flow Velocity in People With Cervicogenic Dizziness.

Objectives: The purpose of this study was to determine the within-session and between-sessions reliability of measuring the vertebral artery blood flow velocities in people with cervicogenic dizziness using Doppler ultrasound at both upper and lower cervical levels.

Methods: Outcome measures were taken on 2 occasions 3 weeks apart with no active treatment provided in between the assessments on 12 participants. Pulsed-wave Doppler ultrasound was used to quantify time-averaged mean velocities through the vertebral artery at upper cervical (C0-1) and lower cervical vertebrae (C5-6).

Raising concerns and reporting poor care in practice.

This article considers the issue of poor care and how nurses should respond when they encounter it. Several reports and inquiries into failings in care have called into question the standards of care provided by nurses. Of equal concern is the observation that in some instances, poor care is unreported.

Student life - Helping nurses to speak up.

How we respond to students who raise concerns is important because the experience will shape their future practice. Students often worry about what they might experience when they return to the practice environment, so need to be reassured they are doing the right thing.

Much more than a mishap.

The Nursing and Midwifery Council (NMC) Code makes it clear that registrants are to prioritise the care and safety of patients.

Adding ultralow-dose naltrexone to oxycodone enhances and prolongs analgesia: a randomized, controlled trial of Oxytrex.

Unlabelled: Oxytrex is a novel drug that combines oxycodone with ultralow-dose naltrexone, an opioid antagonist. Ultralow-dose opioid antagonists have been demonstrated to enhance and prolong opiate analgesia and alleviate opioid tolerance and withdrawal in rodents. This 3-week, Phase II clinical trial assessed safety and analgesic efficacy of Oxytrex in patients with moderate to severe pain from osteoarthritis.

Measuring survival rates from sudden cardiac arrest: the elusive definition.

Background: Measuring survival from sudden out-of-hospital cardiac arrest (OOH-CA) is often used as a benchmark of the quality of a community's emergency medical service (EMS) system. The definition of OOH-CA survival rates depends both upon the numerator (surviving cases) and the denominator (all cases).

Purpose: The purpose of the public access defibrillation (PAD) trial was to measure the impact on survival of adding an automated external defibrillator (AED) to a volunteer response system trained in CPR.

Conducting research using the emergency exception from informed consent: the Public Access Defibrillation (PAD) Trial experience.

Background: The Public Access Defibrillation (PAD) Trial, a prospective, multicenter, randomized clinical trial comparing two prehospital resuscitation strategies, was conducted under the regulations for exception from informed consent (21CFR50.24) in 24 communities in North America. These regulations place additional requirements for human subject protection on investigators and Institutional Review Boards (IRBs), including conducting community consultation (CC) and public disclosure (PD).

Short communication on the influence of position on anterior cruciate ligament injury and reconstruction in recreational rugby football union participants.

The different player positions in rugby union may place varying demands on a reconstructed anterior cruciate ligament (ACL) in regards to 'cutting manoeuvres', this in turn may effect performance. In order to investigate sporting performance post reconstruction, a questionnaire was sent to amateur rugby clubs affiliated to the Oxfordshire Rugby Football Union (R.F.
