Pharmacological modulation of the bradykinin-induced differentiation of human lung fibroblasts: effects of budesonide and formoterol.

Objective: Bradykinin (BK) induces differentiation of lung fibroblasts into myofibroblasts, which play an important role in extracellular matrix remodeling in the airways of asthmatic patients. It is unclear whether this process is affected by antiasthma therapies. Here, we evaluated whether a glucocorticoid, budesonide (BUD), and a long-acting β2-agonist, formoterol (FM), either alone or in combination, modified BK-induced lung fibroblast differentiation, and affected the BK-activated intracellular signaling pathways.

Unprotected left main stenting in the real world: five-year outcomes of the French Left Main Taxus registry.

Aims: Limited long-term data are available to support drug-eluting stent (DES) unprotected left main (LM) intervention. We sought to evaluate long-term outcomes of LM intervention with paclitaxel-eluting stents.

Methods And Results: In this prospective multicentre registry, 291 patients with unprotected LM stenosis underwent percutaneous revascularisation with the TAXUS® Express® stent, using a consistent technical approach for both ostial/shaft and bifurcation lesions (provisional side branch stenting).

Application of one- and two-dimensional NMR spectroscopy for the characterization of Protected Designation of Origin Lambrusco wines of Modena.

Lambrusco is a Protected Designation of Origin (PDO) red wine of Modena (Italy) produced according to the production regulation (Decreto Ministeriale (DM) July 27, 2009; GU no. 184-187-188, 13/08/2009). Here the use of (1)H NMR spectroscopy as molecular fingerprints of several PDO Lambrusco wines was proposed to serve as indicators of authenticity and quality control.

Use of X-ray diffraction technique and chemometrics to aid soil sampling strategies in traceability studies.

Aim of this work is to assess the potentialities of the X-ray powder diffraction technique as fingerprinting technique, i.e. as a preliminary tool to assess soil samples variability, in terms of geochemical features, in the context of food geographical traceability.

Clinical and pharmacological aspects of immunoprophylaxis for respiratory syncytial virus infection in high-risk infants.

Respiratory syncytial virus (RSV) is the leading cause of respiratory tract infection in infants and young children throughout the world. Although preterm birth has been considered for years the major risk factor for severe disease and hospitalization, recent findings indicate that prematurity is not a necessary condition, but one of the independent risk factors for severe RSV infection, together with chronic lung diseases, congenital heart disease and immunodeficiency. Furthermore, over 50% of infants hospitalized for RSV infections during the first year of life are healthy, full-term newborns, suggesting that other environmental and individual factors may be involved.

[Improving dietary habits in the effective prevention of excess weight and obesity].

The new research survey "Okkio alla salute", conducted in children in the 3rd year of elementary school, has confermed the worrisome phenomenon of the high number of obese and overweight children. Therefore, it is necessary, also in light of the few available resources, to fight back against this phenomenon that has been demonstrated to be a cause of disabling illnesses in adults. There must therefore be collaboration between Departments of Prevention and Hygiene and Nutrition services (SIAN) to build valid and efficient pathways.

Primary hyperparathyroidism in older people: surgical treatment with minimally invasive approaches and outcome.

Introduction. Elderly patients with primary hyperparathyroidism (pHPT) are often not referred to surgery because of their associated comorbidities that may increase surgical risk. The aim of the study was to review indications and results of minimally invasive approach parathyroidectomy in elderly patients to evaluate its impact on outcome.

Breathlessness perception assessed by visual analogue scale and lung function in children with asthma: a real-life study.

Background: In children with asthma, discrepancies between objective indicators of airway obstruction and symptom perception are often observed. Although visual analogue scale (VAS) has been proposed as a useful tool for assessing accurate symptom perception, previous studies conducted in children with asthma included only small cohorts. A study was therefore designed to investigate the usefulness of VAS in establishing a reliable relationship between breathlessness perception and lung function in a large cohort of children with clinical diagnosis of asthma.

Prednisolone and prednisone neo-formation in bovine urine after sampling.

The rise in the frequency of detecting prednisolone in bovine urine from northern Italy has come into focus of attention in recent years. The possibility that neo-formation of prednisolone or that prednisone may occur in urine after collection of samples was therefore investigated. Cow urine collected for official routine controls in Lombardy containing more than 80 ng/ml cortisol, and prednisolone and prednisone below the decision limit (CCα) of the method (0.

Weakly acidic gastroesophageal refluxes are frequently triggers in young children with chronic cough.

Objective: To evaluate whether the proportion of acid and weakly acidic refluxes preceding cough bursts could be different in infants, preschool- and school-aged children with chronic, unexplained cough.

Patients And Methods: One hundred six children with unexplained chronic cough, not receiving acid suppressive therapy, underwent impedance-pH monitoring. They were divided into Group A: <2 years (21 pts), Group B: ≥2 to ≤6 years (41 pts), and Group C: >6 years (44 pts).

Exhaled nitric oxide is related to bronchial eosinophilia and airway hyperresponsiveness to bradykinin in allergen-induced asthma exacerbation.

Exhaled nitric oxide (FeNO) has been associated with bronchial eosinophilia and with airway hyperresponsiveness (AHR) in mild stable asthma. We previously demonstrated in a large project that allergen exposure is able to raise FeNO and to worsen AHR to bradykinin. We postulated that allergen-induced increase in FeNO could be related to heightened mucosal eosinophils and AHR to bradykinin in atopic asthma.

Mid-stream vs. first-voided urine collection by using automated analyzers for particle examination in healthy subjects: an Italian multicenter study.

Background: In analogy with other areas of laboratory diagnostics, the pre-analytical phase is the leading source of variability also in urinalysis. We carried out a multicentric study for comparing results obtained from first-voided and mid-stream urine samples.

Methods: Each of the six hospital-based clinical laboratories participating to this study recruited 50 healthy subjects among laboratory staff and/or their relatives.

Pulmonary function and airway responsiveness in young competitive swimmers.

Rationale: Strong physical activities are often associated with large lung volumes and relatively reduced flow, which may represent a physiological variant but also an obstructive abnormality. Competitive swimmers have also spirometric values even larger than other athletes, although they are at increased risk for asthma or airway hyperresponsiveness.

Aim: We aimed to investigate whether lung volumes increase with duration of swimming training and are related to an obstructive abnormality associated with airway hyperresponsiveness and asthma-like symptoms.

French Ministry of Health prospective multicentre study using bio-active stents coated with titanium nitride oxide: the EVIDENCE registry.

Background: Coronary stents have evolved over time, from bare-metal stents to drug-eluting stents, and now to bioactive stents.

Aims: We sought to explore the immediate outcome of the titanium-nitride-oxide-coated bioactive stent, Titan2(®), in real-world practice, and the incidence of major cardiac events at follow-up.

Methods: Consecutive patients admitted for percutaneous intervention for at least one significant (≥50%) lesion in a native coronary artery were treated with Titan2(®) stent implantation.

Morbidity of appendectomy and cholecystectomy in pregnant and nonpregnant women.

Objective: To use the data from the American College of Surgeons (ACS) National Surgical Quality Improvement Program to estimate major postoperative morbidity after 1) appendectomy in pregnant compared with nonpregnant women; and 2) cholecystectomy in pregnant compared with nonpregnant women.

Methods: We selected a cohort of reproductive-aged women undergoing appendectomy and cholecystectomy between 2005 and 2009 from the data files of the ACS National Surgical Quality Improvement Program. Outcomes in pregnant women were compared with those in nonpregnant women.

Heterogeneity of large cell carcinoma of the lung: an immunophenotypic and miRNA-based analysis.

Large cell carcinomas (LCCs) of the lung are heterogeneous and may be of different cell lineages. We analyzed 56 surgically resected lung tumors classified as LCC on the basis of pure morphologic grounds, using a panel of immunophenotypic markers (adenocarcinoma [ADC]-specific, thyroid transcription factor-1, cytokeratin 7, and napsin A; squamous cell carcinoma [SQCC]-specific, p63, cytokeratin 5, desmocollin 3, and Δnp63) and the quantitative analysis of microRNA-205 (microRNA sample score [mRSS]). Based on immunoprofiles 19 (34%) of the cases were reclassified as ADC and 14 (25%) as SQCC; 23 (41%) of the cases were unclassifiable.

Ciclesonide modulates in vitro allergen-driven activation of blood mononuclear cells and allergen-specific T-cell blasts.

Background: Ciclesonide, an inhaled corticosteroid with almost no affinity for the glucocorticoid receptor, is highly effective in downregulating in vitro pro-inflammatory activities of airway parenchymal cells when converted into the active metabolite desisobutyryl-ciclesonide.

Objective: We evaluate whether ciclesonide could effectively downregulate also antigen- or allergen-induced activation of peripheral blood mononuclear cell and of allergen-specific T-cell blasts.

Methods: Peripheral blood mononuclear cells were isolated from non atopic and atopic asthmatic children sensitized to Phleum pratense (PhlP5).

Distribution of T-2 and HT-2 toxins in milling fractions of durum wheat.

The effect of processing on mycotoxin content in milling fractions has been investigated in 10 samples of durum wheat contaminated with T-2 and HT-2 toxins at levels ranging from 97 to 5,954 μg/kg (sum of T-2 and HT-2 toxins). Either naturally contaminated samples or samples artificially inoculated with Fusarium sporotrichioides under field conditions were used. A method based on liquid chromatography-tandem mass spectrometry coupled with immunoaffinity column cleanup was validated in-house for the simultaneous analysis of both toxins in a variety of matrices, including uncleaned wheat, cleaned wheat, screenings, bran, red dog, fine middlings, and semolina.

Early and long-term results of unprotected left main coronary artery stenosis with paclitaxel-eluting stents: the FRIEND (French multicentre RegIstry for stenting of uNprotecteD LMCA stenosis) registry.

Aims: To evaluate the angiographic and clinical outcome of patients undergoing paclitaxel-eluting stent (PES) implantation for unprotected left main coronary artery (ULMCA) stenosis in a "real-world" multicentre, prospective registry. Percutaneous coronary intervention (PCI) is an increasingly utilised method of revascularisation in patients with ULMCA.

Methods And Results: A prospective registry including all patients with a significant (>50%) ULMCA stenosis.

Possibility of myelodysplastic syndromes screening using a complete blood automated cell count.

Diagnosis of MDS has changed during the last years because of the 2008 WHO classification. Complete blood cell count (CBC) is a very important tool both for diagnosis of MDS. The aim of this study was to evaluate if it is possible to use the abnormal signals produced by dysplastic cells to produce a flag "dysplasia" able to identify the patients needing further hematological investigations.

Autostereoscopic three-dimensional viewer evaluation through comparison with conventional interfaces in laparoscopic surgery.

In the near future, it is likely that 3-dimensional (3D) surgical endoscopes will replace current 2D imaging systems given the rapid spreading of stereoscopy in the consumer market. In this evaluation study, an emerging technology, the autostereoscopic monitor, is compared with the visualization systems mainly used in laparoscopic surgery: a binocular visor, technically equivalent from the viewer's point of view to the da Vinci 3D console, and a standard 2D monitor. A total of 16 physicians with no experience in 3D interfaces performed 5 different tasks, and the execution time and accuracy of the tasks were evaluated.
