Context. The international Whole Earth Blazar Telescope (WEBT) consortium planned and carried out three days of intensive micro-variability observations of S5 0716+714 from February 22, 2009 to February 25, 2009. This object was chosen due to its bright apparent magnitude range, its high declination, and its very large duty cycle for micro-variations. Aims. We report here on the long continuous optical micro-variability light curve of 0716+714 obtained during the multi-site observing campaign during which the Blazar showed almost constant variability over a 0.5 mag range. The resulting light curve is presented here for the first time. Observations from participating observatories were corrected for instrumental differences and combined to construct the overall smoothed light curve. Methods. Thirty-six observatories in sixteen countries participated in this continuous monitoring program and twenty of them submitted data for compilation into a continuous light curve. The light curve was analyzed using several techniques including Fourier transform, Wavelet and noise analysis techniques. Those results led us to model the light curve by attributing the variations to a series of synchrotron pulses. Results. We have interpreted the observed microvariations in this extended light curve in terms of a new model consisting of individual stochastic pulses due to cells in a turbulent jet which are energized by a passing shock and cool by means of synchrotron emission. We obtained an excellent fit to the 72-hour light curve with the synchrotron pulse model. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to assess the rate of pressure injury and real predictors thereof in the older adult population with hip fractures in an orthopedic hospital., Methods: In this prospective prognostic cohort study, all patients admitted with fragility hip fractures were monitored over a 12-month period. On a daily basis, ward nurses and physiotherapists assessed the condition of the patients' skin and collected data about all the predictors connected to their healthcare and hospital organization until the patients were discharged from hospital or until the onset of pressure injury., Results: From October 1, 2013, to September 30, 2014, 467 older adult patients with fragility fractures were enrolled in the study. Of these, 27% (n = 127) developed a pressure injury. Multivariate analysis identified the following predictive factors: age older than 81 years, type of surgery, and placing the limb in a foam rubber splint. No other factor connected to the patient or medical, nursing, or rehabilitation treatment was significantly correlated to the onset of pressure injury, even when the univariate analysis showed some of them were possible predictors., Conclusions: Pressure injury in older adults with hip fractures is a relatively common complication, especially in high-risk patients or following certain treatments. These potential indicators could help provide safe and targeted care by preemptively identifying patients at highest risk of pressure injury.

It is clinically relevant to understand whether it is safe to recommend to trained overweight/obese people long-distance treks and whether these experiences could have a negative psychological impact or become even dangerous exposing the trekkers to the risk of clinically silent myocardial damage. To answer these questions we have performed a quantitative/qualitative study comparing the changes in mood profiles, personal views, body composition, and plasma troponin levels of 40 overweight/obese subjects with those of 36 healthy normal weight subjects after the participation in a trek of 388 km from the Adriatic to the Tyrrhenian seas trek: the "Step by step…Italy's coast to coast". The results of this study demonstrate that long-distance treks are a safe activity for trained overweight/obese people which should be recommended because they improve mood, health status, and the relationship of participants with themselves and with the regular practice of exercise with effects similar to those obtained by healthy normal weight subjects.

Unlabelled: Effectiveness of the transparent sterile dressing vs standard to fix the peripheral venous catheter (PVC), on the incidence of phlebitis. A randomized controlled trial., Introduction: The type of dressing could contribute to the incidence of phlebitis, infiltration and accidental removals but the results of the studies are contrasting and samples are limited., Aim: To compare the effectiveness of a transparent polyurethane sterile dressing on the rate of phlebitis associated to peripheral venous catheter (PVC) vs a non sterile sticking plaster in use in current practice (standard dressing)., Design: Randomized controlled trial. Participants. 1061 PVCs (703 patients, adults and children) at a research orthopedic hospital in the north of Italy; 540 PVCs allocated to receive the sterile and 521 the standard dressing., Results: 96 PVCs were excluded for phlebitis, 48 (9.6%) in the sterile and 48 (10.1%) in the standard dressing group, RR 0.96 (95%CI 0.697 - 1.335). Accidental removal of the PVCs was more frequent with the sterile dressing (9.6% vs 6.3%) but the number of catheters removed without complications was larger in the standard dressing group (48.9% vs 54.9% P=0.0503). Eighty-five PVCs were replaced for detachment of the dressing (50, 9.2% sterile and 35, 6.7% standard dressing). The cheapest transparent sterile dressing costs 32 cents while the standard 9 cents., Conclusions: A sticking non sterile plasters is not influential on the rate of phlebitis and ensures an good fix of the PVC compared the transparent sterile dressing to of polyurethane film.

Introduction: Peripheral venous catheters (PVC) may cause complications, specifically local. Their management varies across health care workers and wards, and guidelines recommendations are often weak and based on experts' opinion., Aim: To measure the incidence of PVCs phlebitis, occlusions, accidental removal and infiltrations and their predictive factors in an orthopedic population., Methods: From may 4 2009 to 30, in an orthopedic hospital, data on patients to whom a PVC was inserted were collected: patient's and PVC characteristics, management and securing strategies, until one of the following outcomes: phlebitis, occlusion, accidental removal, infiltration or end of treatment., Results: Overall, 873 patients were recruited and 139 PVCs. The following complications occurred: phlebitis 10.9%; occlusions 16.8%; accidental removals 5.8%, local infiltrations 14.4%; 648 PVCs (46.5%) were removed without complications. The risk for all complications (multivariate analysis) increased with age and for the other complications also with the administration of blood transfusions thorough PVC, irritant drugs and use >3 times/day for phlebitis; small gauge, not using PVC and surgical site infections for occlusions; positioning the PVC in the hand and fixing the PVC with the Chevron method for accidental removals; and female sex, transfusions and thromboembolic therapy for infiltrations., Conclusions: The incidence of phlebitis is high compared to the gold standard of 5%. Knowing the incidence of main complications is a requirement for any improvement strategy and may favor the abandonment of useless or dangerous practices.
