Malattie infiammatorie delle vie aeree superiori
No full textLe vie aeree superiori si estendono dalle narici alla laringe e sono in continuità con le vie aeree inferiori, che si estendono dalla trachea agli alveoli. I due tratti respiratori, superiore e inferiore, hanno molte caratteristiche in comune ma anche caratteristiche distintive. La rinite è rinorrea anteriore e/o posteriore, starnuto, ostruzione e prurito nasali, presenti per almeno 1 ora al giorno per almeno 2 giorni consecutivi. Numerose condizioni, allergiche e non allergiche, possono causare tali sintomi
Higher levels of C-reactive protein and ferritin in patients with overweight and obesity and SARS-CoV-2-related pneumonia
No full textIntroduction: Overweight and obesity are associated with a more severe COronaVirus Disease 19 (COVID-19). Adipose tissue-related chronic inflammation could be a promoter for the occurrence of the cytokine storm that predicts aggravation of COVID-19. The primary aim was to investigate if this increased risk for more severe COVID-19 was associated with a higher inflammatory response. Methods: We enrolled patients <75 years old hospitalized in a medical COVID-19 ward with SARS-CoV-2-related pneumonia. Patients were classified according to BMI as normal weight, overweight, and obesity. Laboratory parameters were measured at admission and every second day during the hospital stay. Results: Ninety patients (64.4% males; median age 61 years) were enrolled. Invasive mechanical ventilation (IMV) was needed in 9% of the patients with normal weight, in 32.4% of the patients with overweight, and in 12.9% of the patients with obesity (p = 0.045). Maximal C-reactive protein (CRP) level during hospital stay was 92 (48-122) mg/L in patients with normal weight, 140 (82-265) mg/L in patients with overweight, and 117 (67-160) mg/L in patients with obesity (p = 0.037). Maximal ferritin values were 564 (403-1,379) μg/L in patients with a normal weight, 1,253 (754-2,532) μg/L in patients with overweight, and 828 (279-1,582) μg/L in patients with obesity (p = 0.015). Conclusion: Patients with overweight and obesity required more IMV and had higher peaks of CRP and ferritin than patients with normal weight during COVID-19
Message from Col. [Excised] [Release of Detainees from Camp Bucca]
No full textAuthor of first e-mail has been instructed to release adult detainees at Camp Bucca in Iraq but is unable to do so because he lacks the necessary paperwork. He requests a list of detainees that are subject to a CID hold and so cannot be released. Respondent suggests that all detainees with no paperwork should be scheduled for release and that he will red flag any detainees with a CID hold.Made available in DSpace on 2012-10-10T14:37:37Z (GMT).

I loop recorder impiantabili di nuova generazione possono essere gestiti in maniera sicura ed efficace da personale infermieristico formato
No full textIntroduction. Im-plantable plantable loop recorders (ILR) are recommended for several cardiac disorders: the recent miniaturization processes eased their implant and management. Aim. To describe the advantages of the ILR implant, patients' education and remote control performed by expert certified nurses. Methods. Retrospective analysis of consecutive ILR implants of our centre, preformed between May and December 2016: the complications occurred in patients implanted by doctors and nurses were described. Nurses were certified after a two days course and 3 implants assisted by a medical doctor. Results. 157 patients were implanted with a ICM Reveal LINQ (Med-tronic): 74 (47%) by physicians electrophysiologists and 83 (53%) out of the electrophysiology room, by certified nurses. The two groups of patients were not fully comparable because more complex patients were implanted by the physician. All the loop recorders were easily implanted adverse without events during the procedure and after 30 days. Two minor bleedings occurred 24 hours after the implant: 1 in a patient implanted by a physician and the other by a nurse. Both were rapidly solved by finger pressure. Conclusions. The ILR implants can be safely performed by trained nurses, out of the elettrophysiology room, with benefits for the patients and the hospital
Dynamics of the Pantograph-Catenary System
No full textPantograph-catenary interaction is a critical issue for electrified railway systems, as it represents a limiting factor for the maximum speed at which the electric rolling stock can be operated and, at the same time, strongly affects the reliability, availability and maintainability of both the rolling stock and the infrastructure. This chapter reviews recent research on pantograph-catenary interaction. A general review of dynamic problems related to pantograph-catenary systems is provided, and numerical methods currently used to predict the behaviour of the system under given operating conditions are presented. Experimental techniques for laboratory and line tests on pantographs are introduced, followed by a description of wear and damage phenomena arising at the interface between the pantograph head and the overhead contact line. Finally, emerging long-term trends are outlined, considering in particular active pantograph control, condition monitoring applications, pantograph aerodynamics and current collection from an overhead contact line for heavy road vehicles
Influence of mastication on gastric emptying
No full textThe role of mastication on digestion efficiency remains to be demonstrated. This study investigates whether masticatory function influences gastric emptying rate. Twelve normal volunteers were studied on two occasions after ingestion of the same test meal containing ham cubes, crackers, and egg (mixed with 13C-octanoic acid), chewed, in random order, either with 50 masticatory cycles or with 25 cycles, swallowing ham cubes whole. Lag phase (Tlag) and gastric half-emptying time (T1⁄2) were measured by means of the 13C-octanoic acid breath test. Trituration performance was assessed by the sieve test, and was expressed as the percentage of ham particles ≤ 1 mm after 50 masticatory cycles. Tlag and T1⁄2 were significantly shorter when the meal was chewed with 50 cycles than with 25 cycles (Tlag 25.9 ± 3.8 vs. 36.4 ± 4.1 min, p = 0.017; T1⁄2 49.1 ± 5.7 vs. 62.5 ± 6 min, p = 0.009). Trituration performance was inversely related to both Tlag (r = 0.621, p = 0.031) and T1⁄2 (r = 0.699, p = 0.012). Comminution of food influences significantly gastric emptying rates
