Late-asthma onset and associated factors
2016
Although asthma is usually considered to originate in childhood, adult-onset is being increasingly reported. Aim: to assess factors associated to early- (<18 yrs) and late-onset (≥18 yrs) asthma. Methods: Data from a web-based Italian severe/uncontrolled asthma (SUA) registry (released in 2014), including 577 SUA subjects from 6 clinical and epidemiological Italian centres (Pisa1, Perugia, Ancona, Verona, Palermo, Pisa2). Results: 77.5% of SUA subjects had a late-onset asthma. Among subjects with early-onset asthma there were higher frequencies of allergic asthma (92.1 vs 76.4%), asthma familiarity (52.8 vs 42.8%), seasonal symptoms (51.3 vs 27.6%), active smoking habits (8.5 vs 4.4%) and u…
Community acquired pneumonia in children: Treatment of complicated cases and risk patients. Consensus statement by the Spanish Society of Paediatric …
2015
The incidence of community-acquired pneumonia complications has increased during the last decade. According to the records from several countries, empyema and necrotising pneumonia became more frequent during the last few years. The optimal therapeutic approach for such conditions is still controversial. Both pharmacological management (antimicrobials and fibrinolysis), and surgical management (pleural drainage and video-assisted thoracoscopic surgery), are the subject of continuous assessment. In this paper, the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases have reviewed the available evidence. Consensus treatment guidelines are prop…
Is kidney a new organ target in patients with obstructive sleep apnea? Research priorities in a rapidly evolving field.
2021
Abstract The bidirectional relationship between sleep disordered breathing and chronic kidney disease (CKD) has recently gained a lot of interest. Several lines of evidence suggest the high prevalence of coexistent obstructive sleep apnea (OSA) in patients with CKD and end-stage renal disease (ESRD). In addition, OSA seems to result in loss of kidney function in some patients, especially in those with cardio-metabolic comorbidities. Treatment of CKD/ESRD and OSA can alter the natural history of each other; still better phenotyping with selection of appropriate treatment approaches is urgently needed. The aim of this narrative review is to provide an update of recent studies on epidemiologic…
Perioperative management of obstructive sleep apnea: A systematic review
2018
Introduction Obstructive sleep apnea (OSA) is the leading sleep disordered breathing condition, with a prevalence rate of moderate to severe OSA of approximately 10-17% in the general population. Evidence acquisition We performed an Ovid-Medline search of all articles published up to August 2016. We included all articles providing updated evidence on epidemiology, pathophysiologic mechanisms and perioperative interventions. Evidence synthesis OSA is associated with a number of comorbidities and increased perioperative risks. Although in-laboratory polysomnography represents the gold-standard for diagnosis of OSA, it is costly and time-consuming. Anesthesiologists may screen patients for OSA…
Longitudinal Asthma Patterns in Italian Adult General Population Samples: Host and Environmental Risk Factors.
2020
Background: Asthma patterns are not well established in epidemiological studies. Aim: To assess asthma patterns and risk factors in an adult general population sample. Methods: In total, 452 individuals reporting asthma symptoms/diagnosis in previous surveys participated in the AGAVE survey (2011–2014). Latent transition analysis (LTA) was performed to detect baseline and 12-month follow-up asthma phenotypes and longitudinal patterns. Risk factors associated with longitudinal patterns were assessed through multinomial logistic regression. Results: LTA detected four longitudinal patterns: persistent asthma diagnosis with symptoms, 27.2%
Randomized controlled study of a mandibular advancement appliance for the treatment of obstructive sleep apnea in children: A pilot study
2015
Background: The current limited evidence may be suggestive that mandibular advancement appliance (MAAs) result in improvements in AHI scores, but it is not possible to conclude that MAAs are effective to treat paediatric OSA. There are significant weaknesses in the existing evidence due primarily to absence of control groups, small sample sizes, lack of randomization and short-term results. Aim: the objective of the present study was to evaluate MAAs in children with OSA. Material and Methods: Children presenting an apnea-hypopnea index (AHI) greater than or equal to one event per hour were considered to be apneic. This group of children with AHI greater than or equal to one was randomly di…
PROSPECTIVE, RANDOMIZED, CROSSOVER COMPARISON OF SUBLINGUAL APOMORPHINE (3 mg) WITH ORAL SILDENAFIL (50 mg) FOR MALE ERECTILE DYSFUNCTION
2004
Abstract: Purpose: We established the efficacy and safety of sublingual apomorphine compared with oral sildenafil. in comparable groups of patients with erectile dysfunction (ED). Materials and Methods: This prospective, randomized, crossover study included 77 heterosexual men with ED of various etiologies and severities. A total of 62 men were randomized but only 34 were evaluable for efficacy and tolerability. The study started with a run-in period of 2 to 4 weeks. The first 4 weeks of treatment were followed by a washout period of 4 weeks, after which patients changed to the alternate treatment for an additional 4-week period. The sequence of the 2 treatments was established by a randomi…
Increased leptin/leptin receptor pathway affects systemic and airway inflammation in COPD former smokers

It is involved in inflammatory diseases such as chronic obstructive pulmonary disease (COPD) and its deficiency is associated with increased susceptibility to the infection. The leptin receptor is expressed in the lung and in…
Relaxation and cGMP formation in response to sildenafil and sodium nitroprusside in saphenous veins from normotensive and hypertensive patients1
2002
Abstract Background This study was designed to measure cyclic guanosine 3′5′ monophosphate (cGMP) formation and relaxation response to sildenafil given either alone or in combination with sodium nitroprusside in saphenous veins obtained from normotensive and hypertensive patients. Methods Saphenous vein rings were obtained from 13 hypertensive and nine normotensive patients undergoing coronary artery bypass surgery. The vein rings were suspended in organ bath chambers for isometric recording of tension. The effect of sildenafil on sodium nitroprusside-induced cGMP formation was also assessed. Results Sildenafil (10 nmol/L to 100 μmol/L) and sodium nitroprusside (0.01 to 100 nmol/L) caused c…
May Dyspnea Sensation Influence the Sexual Function in Men With Obstructive Sleep Apnea Syndrome? A Prospective Control Study
2019
Abstract Introduction Dyspnea sensation is frequently present in obstructive sleep apnea syndrome (OSA) patients; however, its possible influence on sexual function and body image has not been well analyzed. Aims To evaluate sexual function, the prevalence of sexual dysfunction (SD), and body image during sexual activity and its relationship with dyspnea in men with OSA. Methods 129 men were included in the prospective study, with 61 diagnosed with OSA (cases) and 68 age- and BMI-matched healthy control subjects. Patients were assessed for the severity of heart failure by the New York Heart Association scale and dyspnea by the Visual Analogue Scale. OSA was confirmed by in-laboratory polyso…
