Battery Longevity Comparison of Two Commonly Available Dual Channel Implantable Pulse Generators Used for Subthalamic Nucleus Stimulation in Parkinson's Disease.

Objectives: Deep brain stimulation for Parkinson's disease (PD) utilises an implantable pulse generator (IPG) whose finite lifespan in non-rechargeable systems necessitates their periodic replacement. We wish to determine if there is any significant difference in longevity of 2 commonly used IPG systems; the Medtronic Kinetra, and the Medtronic Activa Primary Cell (PC), which has come to replace it.

Methods: All patients with bilateral Subthalamic Nucleus stimulators for PD performed in our centre were included.

Subthalamic deep brain stimulation under general anesthesia and neurophysiological guidance while on dopaminergic medication: comparative cohort study.

Objectives: The authors have previously reported on the technical feasibility of subthalamic nucleus deep brain stimulation (STN DBS) under general anesthesia (GA) with microelectrode recording (MER) guidance in Parkinsonian patients who continued dopaminergic therapy until surgery. This paper presents the results of a prospective cohort analysis to verify the outcome of the initial study, and report on wider aspects of clinical outcome and postoperative recovery.

Methods: All patients in the study group continued dopaminergic therapy until GA was administered.

It's every nurse's duty to help prevent terrorism.

Manchester is my home city and, like many people across the North West and in London, I have been devastated by the appalling terrorist attacks of recent months, which have felt very close to home. We can all be proud of the incredible way that the NHS family responded to the attacks, swiftly and with such heroic professionalism.

A Dual-Administration Microtracer Technique to Characterize the Absorption, Distribution, Metabolism, and Excretion of [ C]Seletalisib (UCB5857) in Healthy Subjects.

Phosphoinositide 3 kinases are targets for development of small-molecule inhibitors to disrupt progression of immune-inflammatory diseases. This phase 1 open-label study (Eudract 2014-005353-39) evaluated the safety and relative bioavailability of 2 new seletalisib (UCB5857) formulations (A and B) compared with a reference formulation. Absolute bioavailability (period 1a, n = 6) and disposition and metabolism (period 1b, n = 6) of the reference formulation were evaluated: healthy subjects received 30 mg orally plus ∼20 μg of a C-labeled microtracer (intravenously in 1a, orally in 1b).

We have the power to combat modern slavery.

There are more individuals occupying positions of slavery globally today than at any other point in history. It is estimated that in the UK alone there are more than 13,000 people living in slavery.

Nursing at the centre of community services.

This article sets out how changes to the health and social care landscape puts community and primary care nursing centre-stage.

Human saphenous vein contains both endothelin ETA and ETB contractile receptors.

We have investigated the endothelin receptor subtypes mediating contraction in isolated preparations of human saphenous vein. Endothelin-1 (EC50: 17.8 nM), endothelin-3 (EC50: 82.

Endothelin ETA and ETB receptors mediate vascular smooth-muscle contraction.

Endothelin (ET) ETA receptors on vascular smooth muscle are believed to mediate the vasoconstrictor effects of ET isopeptides, and ETB receptors on the endothelium are thought to mediate the vasodilator effects. This study has investigated the receptors mediating endothelin-induced contraction of isolated ring preparations of rat thoracic aorta (RTA) and rabbit carotid artery (RCA), pulmonary artery (RPA), and jugular vein (RJV). In RTA and RCA, ET-1 (EC50 4.

Early diagnosis of acute myocardial infarction by CK-MB mass measurements.

We have studied the changes in creatine kinase (CK) and creatine kinase MB (CK-MB) activity and concentration for the diagnosis of acute myocardial infarction in 73 patients admitted to the coronary care unit with cardiac symptoms of 12 h duration or less. Serial blood samples were obtained for an 8 h period following admission and CK, CK-MB activity and concentration measured. We compared the performance of single values at optimized diagnostic cut-offs and incremental change (log slope) for all three measurements.

Absence of circulating products of oxygen derived free radicals in acute severe asthma.

Oxygen derived free radicals (ODFRs), generated by eosinophils, neutrophils, alveolar macrophages and mast cells, have been proposed as important mediators of inflammatory damage in asthma. We attempted to assess the role of these free radicals in patients with acute asthma by determining serum concentrations of phospholipid-esterified 9, 11 and the parent 9, 12-linoleic acid isomers (9, 11-LA, 9, 12-LA), using HPLC and diode array detection. The diene conjugate, 9, 11-LA, has been shown to be a sensitive and specific marker of free radical activity in other inflammatory conditions.

An improved fluorimetric assay for brain monoamine oxidase.

A fluorimetric assay for monamine oxidase that uses kynuramine as the substrate is described. This method is more economic, rapid, reproducible, and sensitive than other similar procedures. Its validity has been confirmed by the study of the subcellular distribution, the effects of inhibitors, and the kinetics of enzyme activity.
