Kinetics of circulating endothelial progenitor cells in patients undergoing carotid artery surgery.
Endothelial progenitor cells (EPCs) are primitive cells found in the bone marrow and peripheral blood (PB). In particular, the potential of EPCs to differentiate into mature endothelial cells remains of high interest for clinical applications such as bio-functionalized patches for autologous seeding after implantation. The objective of this study was to determine EPCs' kinetics in patients undergoing carotid artery thromboendarterectomy (CTEA) and patch angioplasty. ⋯ CTEA results in short-term downregulation of circulating EPCs and SDF-1α levels. Rapid return to baseline levels might indicate participation of EPCs in repair mechanisms following vascular injury.

ReviewPatient considerations and drug selection in the treatment of idiopathic pulmonary fibrosis.
Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease of unknown cause. Approximately 5,000 people are diagnosed with IPF in the UK every year. People with IPF suffer significant morbidity and, without any curative treatment at present, survival rates remain poor with a median survival of 3 years. ⋯ We discuss pharmacological and nonpharmacological aspects of providing best supportive care for patients with IPF. However, few good quality studies exist focusing on controlling symptoms specifically in patients with IPF, and recommendations are often extrapolated from evidence in other chronic diseases. In covering these topics, we hope to provide readers with a comprehensive review of the available evidence pertaining to all aspects of care for patients suffering with IPF.

ReviewNew combinations in the treatment of COPD: rationale for aclidinium-formoterol.
The current guidelines on chronic obstructive pulmonary disease (COPD) recommend the prominent use of bronchodilators, including long-acting β2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs), while inhaled corticosteroids are recommended only in patients with severe disease or frequent exacerbations. LABA-LAMA combinations are indicated when single bronchodilators are insufficient to control COPD. A number of LABA-LAMA combinations are available, based on twice-daily or once-daily administration according to the 12- or 24-hour duration of action, respectively. ⋯ The overall incidence of adverse events was low and comparable to placebo. These data define the aclidinium-formoterol fixed-dose combination as a new treatment option for patients with COPD. The need for twice-daily administration could be an apparent disadvantage compared to the available once-daily LABA-LAMA combinations, but the immediately perceived benefit in reducing dyspnea due to the fast onset of action, as well as reported correct patient use and satisfaction with the Genuair inhaler might prove useful in favoring adherence.

Patients' safety: is there a systemic release of gentamicin by gentamicin-coated tibia nails in clinical use?
Osteitis is one of the most serious complications in orthopedic surgery. Expert Tibia Nail (ETN) PROtect™ coated with a biodegradable layer of gentamicin-laden polymer was developed for prophylaxis of osteomyelitis. In systemic administration, gentamicin has only a small therapeutic index and serious side effects; it is potentially nephrotoxic as well as ototoxic. It is not yet known if relevant gentamicin concentrations are released into the systemic circulation after implantation of gentamicin-coated nails. In order to evaluate the patients' risks profiles and increase patient safety, we measured gentamicin levels in pre- and postoperative serum samples of patients undergoing implantation of ETN PROtect. ⋯ Our findings suggest that there is no relevant release of gentamicin into the systemic circulation causing a systemic effect, and serious side effects due to gentamicin-coated tibia nails should not be feared. Postoperative monitoring of renal function does not seem necessary because of the implantation of ETN PROtect.

Sudoscan as a noninvasive tool to assess sudomotor dysfunction in patients with Fabry disease: results from a case-control study.
Hypohidrosis is a frequent and early symptom in patients with Fabry disease. Studies have reported improved sweating in patients treated with enzyme-replacement therapy. A new method, Sudoscan, has been developed that is noninvasive, is quantitative, and can quickly evaluate sweat gland function. ⋯ Among patients, 8/18 (44.5%) had a sudomotor dysfunction, moderate in three and severe in five cases. Hand and feet ESCs were significantly lower in those with hypohidrosis/anhidrosis compared to those without (P=0.0014 and P=0.0056, respectively). This study showed that Sudoscan provided a quick, noninvasive, and quantitative measurement of sudomotor function in Fabry disease patients.
