Abstract
Summary Background. Chronic rhinosinusitis (CRS) is an inflammatory disease that affects the nasal mucosa and the paranasal sinuses. CRS can be associated by nasal polyposis (CRSwNP phenotype) in up to 30% of patients and it is frequently associated with bronchial asthma. CRSwNP shows predominantly an underlying activation of type 2 inflammatory pathways with the involvement of eosinophils, IgE, interleukin (IL)-4, IL-5 and IL-13. Biological drugs that target these inflammatory cytokines are currently a therapeutic option recognized by guidelines for the treatment of uncontrolled form of the disease. Methods. As part of the activity of the "ARIA-Italy" working group, a panel of 255 Italian Ear, Nose and Throat (ENT) specialists, pneumologists and immuno-allergologists actively participated in this national survey and answered a series of questions geared toward understanding the main criteria for patient characterization and therapeutic decision, highlighting multidisciplinarity, and the implementation of the management of CRSwNP patients, as a part of the precision medicine concept and the appropriate use of the biologicals. Results. Two hundred and fifty-five experts and specialists participated in the survey. Conclusions. The results of this survey obtained from an extensive number of active specialists throughout Italy allow some important concluding remarks to be drawn. The main points of agreement were that multidisciplinary care teams provide many benefits but that, once the team is established, meetings and communication between members must be coordinated. Finally, the dissemination of national disease registries and the continuous updating of guidelines and position papers related to CRSwNP and comorbidities should be encouraged.

Fine particulate matter and sleep-disordered breathing severity in a large Italian cohort. Sleep Breath 2024; 28:371-375. [PMID: 37718355 DOI: 10.1007/s11325-023-02918-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 09/02/2023] [Accepted: 09/06/2023] [Indexed: 09/19/2023]
Abstract
BACKGROUND Air pollution and obstructive sleep apnea (OSA) are both linked with cardiovascular co-morbidities and share similar pathophysiological mechanisms. A causal association between the two has been postulated. However, the results of the studies on this topic are conflicting mainly because of the lack of adjustment for important confounders such as seasonality and temperature. We aimed to evaluate if such an association exists in a highly polluted area like Lombardy region (Italy) when accounting for all confounders. METHODS Data of adult patients seen at the Sleep Disorder Centre in Milan from 2010 to 2020 were analysed and the main polygraphic data were retrieved. Air pollutant concentrations of the following pollutants NO2, O3, PM2.5, and PM10 were collected through monitoring stations. RESULTS A total of 3493 patients were included: males (2358, 67.5%) mean age 60.1 (SD = 14.3) years, BMI 29.2 (6.2) kg/m2, mean AHI 16.5 (18.1) events/h. After adjusting for all confounders, in the multivariable analysis, the only associations that remained significant were long-term exposure to O3 with indexes of OSA severity (AHI and ODI) but only in spring. Furthermore, a positive association was seen between long-term exposure to PM10 and ODI but in springtime only. CONCLUSION The findings of the current study does not support an association between fine particulate matter and OSA severity.

Abstract
Advanced heart failure (HF) is associated with a very poor prognosis and places a big burden on health-care services. The gold standard treatment, i.e. long-term mechanical circulatory support or heart transplantation, is precluded in many patients but observational studies suggest that the use of SNP might be associated with favourable long-term clinical outcomes. We performed a metanalysis of published studies that compared sodium nitroprusside (SNP) with optimal medical therapy to examine the safety and efficacy of SNP as part of the treatment regimen of patients hospitalized for advanced heart failure (HF). We searched PUBMED, EMBASE and WEB OF SCIENCE for studies that compared SNP with optimal medical therapy in advanced HF on July 2022. After screening 700 full-text articles, data from two original articles were included in a combined analysis. The analysis demonstrated a 66% reduction in the odds of death in advanced HF patients treated with SNP. The results show the potential importance of the inclusion of SNP in the treatment regimen of patients hospitalized because of advanced HF and underlines that controlled, randomized studies are still required in this condition.

Abstract
Abstract
Background
The APOA1 gene encodes the precursor of apolipoprotein AI (ApoAI), whose mature form is the major component of high–density lipoproteins. APOA1 mutations may cause a form of hereditary amyloidosis (AApoAI). Only very small case series of patients with AApoAI are available.
Methods
We examined 189 consecutive subjects with the heterozygous APOA1 Leu75Pro mutation referred for cardiac screening over a 10–year timespan at the Spedali Civili of Brescia (Italy).
Results
Subjects (men 54%, median age 55 years, renal disease 39%, liver disease 31%) had a median left ventricular ejection fraction (LVEF) of 60% (55–66), did not display a prominent diastolic dysfunction (E/e’ ratio 7 [6–10]) nor LV hypertrophy (LV mass index [LVMI] 92 g/m2 [74–111]). LV global longitudinal strain (GLS) (–19% [–21 to –17]), and mass to strain ratio (MSR) (10.0 [6.8–12.1]) were within normal limits. Age correlated with several echocardiographic parameters, including interventricular septal (IVS) thickness (r = 0.484), LVMI (r = 0.459), E/e’ (r = 0.501), and right ventricular free wall thickness (r = 0.459) (all p < 0.001). Some individuals displayed echocardiographic red flags of cardiac amyloidosis (CA; “granular sparkling” of the IVS, 19%; pericardial effusion, 11%; apical sparing, 10%; thickened atrioventricular valves, 8%). Thirteen out of 96 (14%) fulfilled non–invasive criteria for CA. Twenty–nine subjects died over 5.8 years (4.1–8.0), with 10 deaths for cardiovascular causes; 14 out of 182 (8%) were hospitalized because of HF, and 17 (9%) died for cardiovascular causes or were hospitalized for HF. Individuals with suspected CA had a much higher risk of all–cause death (p = 0.009), cardiovascular death (p < 0.001), cardiovascular death or HF hospitalization (p < 0.001), and HF hospitalization alone (p < 0.001). Furthermore, subjects with either renal or liver involvement had a higher risk of events and a worse outcome.
Conclusions
In subjects with an amyloidogenic APOA1 mutation, transthoracic echocardiography showed only minor signs of cardiac disease. The correlations between age and echocardiographic findings suggested a progressive increase in wall thickness, a decline in systolic and diastolic function, and a greater uncoupling between LV mass and contractility over time. Subjects with both renal and liver disease displayed the most evident signs of biventricular involvement and had a worse outcome.

Abstract
Abstract
Background
Obstructive sleep apnoea (OSA) is characterised by the collapse of the upper airway during sleep, which determine intermittent hypoxia and sleep fragmentation leading to snoring, impaired cognitive function, excessive daytime sleepiness, and cardiovascular impairments. These disorders have a significant impact on the quality of life and health of both patient and partner, determining stress and frustration also to the couple relationship, and to the workplace. Although the gold standard of treatment for OSA is the use of continuous positive airway pressure (CPAP), many patients find it uncomfortable both for them and for their partners (difficulty in partner intimacy, fear of disturbing their partner's sleep) with consequent low adherence to treatment in about 50% of OSA patients.
For these reasons, efforts to develop drug therapies for the treatment of OSA have been ongoing for at least 20 years. Recently, we conducted a randomized controlled trial (RCT) in Italy to test the combination of reboxetine (a noradrenergic agent) and oxybutynin (an antimuscarinic) for OSA treatment with promising results. The aim of this study is to understand how OSA drug therapy has influenced couples' life.
Methods
The study was conducted from February to March 2020 by the research nurse who participated during the trial. We interviewed 11 patients participating in the pharmacological RCT and 7 partners. The data analysis was conducted in order to collect the subjects' answers in categories, and to identify a core category as the central element for the explanation of the process.
Results
Interviews permitted to extrapolate 6 main categories and the relative subcategories for patients: 1) OSA: unconscious danger; 2) OSA and couple life (subcategories: sleepiness and nervousness, lack of sleep); 3) transitory situations; 4) drug therapy and couple (subcategories:change in intimacy and sleep quality); 5) motivation to help others (subcategories: therapy recommended for everyone; intention to continue); 6) partner awareness helps in adherence to therapy (subcategories: partner as caregiver, presence and proximity, partner support). While for partners, 7 main categories and the relative subcategories emerged: 1) apprehension and concern for the partner; 2) repercussions on daily life (subcategorie: discomfort); 3) OSA and the couple's lives; 4) drug therapy and couple; 5) support during therapy (subcategorie: before therapy, during therapy); 6) changes during drug therapy; 7) recommended therapy (subcategories: helping others, partner support). “The OSA is our problem” was the core category of the study that linked the categories together.
Conclusions
Drug therapy is well embraced by both patients and partners as it allows the couple to recover intimacy during sleep and in daily life. The results of this study provide useful information on the need to involve the partner in order to promote adherence to therapy.

Abstract
Abstract
Background
Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, literature data are progressively accumulating, attesting to the possible prognostic role of cardiac troponins in patients who need hospitalization because of COVID-19 infection.
Purpose
To assess whether myocardial injury (measured by high sensitivity troponins) is an independent cause of disease severity and prognosis.
Methods
We performed a patient-level metanalysis (PROSPERO ID: CRD42020213209) in unselected patients hospitalized because of COVID-19 infection in whom the severity of respiratory failure was also evaluated at admission. To allow for comparison, troponin values were normalized to their threshold levels to obtain a normalized troponin (nTn) value which was used as a continuous variable in all analysis.
Results
A total of 722 patients were included in the analysis. Of note, patients who had elevated troponins at hospital admission had a significantly lower oxygenation status than those with normal nTn (PaO2/FiO2 232±215 vs. 276±124 mmHg/%; p<0.001). On the contrary, those with cardiovascular comorbidities had similar PaO2/FiO2 but higher nTn than those without (5.6817 vs. 2.1110 ng/mL; p=0.002).
After a median follow-up of 14 days, 180 deaths were observed. At multivariable regression analysis, age, male sex, moderate-severe renal dysfunction (eGFR <30 mL/min/m2) and lower PaO2/FiO2, were independent predictor of death (igure 1). The restricted cubic spline curves in Figure 2A and 2B show the hazard ratios (HRs) and 95% confidence interval for death according to nTn and PaO2/FiO2 levels as continuous variables. A linear increase in the HR is observed with lower PaO2/FiO2 values below the normal value of 300. On the contrary, the nTn spline curve is near-flat with large confidence interval for values above the normality thresholds.
Conclusion
In patients hospitalized for COVID-19, mortality is mainly driven by gender, age and respiratory failure while myocardial damage is not an independent predictor of worse survival when respiratory function is accounted for.

Abstract
Summary Allergic rhinitis (AR) is a common disease affecting up to 40% of the general population worldwide. In the Coronavirus 2019 (COVID-19) pandemic era, many observational studies analysing the effect of asthma and chronic obstructive pulmonary disease on the risk of developing COVID-19 were conducted, while data on AR are limited.In this paper, we review the risk of developing SARS-Cov-2 infection carried by AR patients, the outcomes of those with COVID-19 disease, and the COVID-19 influence on the allergic and nasal symptoms and the psychological status of AR patients, in both adult and paediatric populations.AR patients seem to be protected from COVID 19 infection. Even if data about the influence of AR on the severity of COVID-19 disease are still not conclusive, it seems that being an AR patient does not increase the risk of poor COVID-19 prognoses. The clinical manifestation of AR can be distinguished by COVID-19 symptoms. Treating AR adequately is also strongly recommended, especially during pandemic.

An intertidal life: Combined effects of acidification and winter heatwaves on a coralline alga (Ellisolandia elongata) and its associated invertebrate community. MARINE ENVIRONMENTAL RESEARCH 2021; 169:105342. [PMID: 33933902 DOI: 10.1016/j.marenvres.2021.105342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 04/01/2021] [Accepted: 04/14/2021] [Indexed: 06/12/2023]
Abstract
In coastal marine ecosystems coralline algae often create biogenic reefs. These calcareous algal reefs affect their associated invertebrate communities via diurnal oscillations in photosynthesis, respiration and calcification processes. Little is known about how these biogenic reefs function and how they will be affected by climate change. We investigated the winter response of a Mediterranean intertidal biogenic reef, Ellissolandia elongata exposed in the laboratory to reduced pH conditions (i.e. ambient pH - 0.3, RCP 8.5) together with an extreme heatwave event (+1.4 °C for 15 days). Response variables considered both the algal physiology (calcification and photosynthetic rates) and community structure of the associated invertebrates (at taxonomic and functional level). The combination of a reduced pH with a heatwave event caused Ellisolandia elongata to significantly increase photosynthetic activity. The high variability of calcification that occurred during simulated night time conditions, indicates that there is not a simple, linear relationship between these two and may indicate that it will be resilient to future conditions of climate change. In contrast, the associated fauna were particularly negatively affected by the heatwave event, which impoverished the communities as opportunistic taxa became dominant. Local increases in oxygen and pH driven by the algae can buffer the microhabitat in the algal fronds, thus favouring the survival of small invertebrates.

Abstract
The aim of this study was to optimize the parameters of the complex melt-emulsification process coupled with the spray-drying, in order to maintain the balance between solid lipid microparticles (SLMs) powders aerodynamic performance and salbutamol sulfate release rate. Quality target product profile was identified and risk management and principal component analysis were used to guide formulation development. Obtained dry powders for inhalation (DPIs) were evaluated in terms of SLMs size distribution, morphology, true density, drug content, solid state characterization studies, in vitro aerosol performance and in vitro drug release. SLMs micrographs indicated spherical, porous particles. Selected powders showed satisfactory aerosol performance with a mean mass aerodynamic diameter of around 3 μm and acceptable fine particle fraction (FPF). Addition of trehalose positively affected SLMs aerodynamic properties. The results of in vitro dissolution testing indicated that salbutamol sulfate release from the tested SLMs formulations was modified, in comparison to the raw drug release. In conclusion, SLMs in a form of DPIs were successfully developed and numerous factors that affects SLMs properties were identified in this study. Further research is required for full understanding of each factor's influence on SLMs properties and optimization of DPIs with maximized FPFs.

Abstract
Introduction
Positive airway pressure (PAP) treatment modifies blood pressure (BP) in patients with obstructive sleep apnea (OSA). We aimed to explore which factors that influence the BP response to PAP therapy in the European Sleep Apnea Database (ESADA).
Methods
A total of 2662 OSA patients with PAP therapy ≥90 days were included in the analysis (74% male, age 55±11 years, body mass index 32.3±6.1 kg/m2, 47% hypertensives, apnea-hypopnea index 40±24 events/h, treatment duration 1.0±1.1 years, PAP compliance 5.2±1.9 h/day). Anthropometric data, co-medications and office BP were assessed at baseline and follow-up visit.
Results
Systolic and diastolic BP were modestly reduced after PAP therapy compared to baseline (133±17 vs. 134±17 mmHg, 78±11 vs. 81±11 mmHg, p<0.001, respectively). In a generalized linear model controlling for anthropometric, PAP compliance and follow-up time, severe OSA at baseline (β [95% CI] −3.2 [−5.1 to −1.3], p=0.001), hypertension status (−2.0 [−3.3 to −0.7], p=0.003), weight reduction >2 kg at follow up (−2.0 [−3.7 to −0.4], p=0.016), and use of auto-adjusted PAP (−1.3 [−2.5 to −0.02], p=0.046) were associated with a reduction of systolic BP at follow-up.
Conclusions
BP reduction following PAP treatment in patients with moderate to severe OSA was modest. We identified several predictors of a favorable BP response including the use of auto adjusted PAP. Our findings suggest that weight reduction strategies in addition to PAP treatment should be considered to obtain adequate BP control in OSA patients.

Abstract
Background:Evidence on the efficacy of Mepolizumab (MEPO) in Eosinophilic Granulomatosis with Polyangiitis (EGPA) is scarce [1].Objectives:To assess the efficacy and safety of MEPO in real-life clinical practice.Methods:We retrospectively included patients diagnosed with EGPA and treated with MEPO (100 or 300 mg/month). MEPO efficacy was evaluated in the first 12 months in terms of systemic disease and asthma control. The occurrence of any adverse event (AE) was recorded.Results:142 patients were included (38% males; median age 46.4 (IQR 36.7-54.4); 110 and 32 on MEPO 100 and 300 mg/month, respectively). General, ear-nose-throat, pulmonary, and neurological symptoms significantly decreased during treatment (table 1). MEPO accounted for a significant reduction in the BVAS (figure 1) and for a steroid sparing effect (figure 2). The proportion of patients with asthma attacks decreased by 90% at 12 months compared to t0, and asthma-related emergency accesses dropped from 17.4% to 2.3%. Overall, 21.1% of patients had a non-serious AE.Table 1.Control of clinical symptomsMEPO beginning (t0)3 monthsp-value(t3 vs t0)6 monthsp-value(t6 vs t0)12 monthsp-value(t12 vs t0)N obsN=142N=135N=123N=89General symptoms40 (28.2%)17 (12.6%)<0.00119 (15.5%)<0.00113 (14.6%)0.002Cutaneous manifestations13 (9.2%)6 (4.4%)0.0085 (4.1%)0.0254 (4.5%)0.180ENT manifestations106 (74.7%)52 (38.5%)<0.00144 (35.8%)<0.00129 (32.6%)<0.001Pulmonary manifestations130 (91.6%)59 (43.7%)<0.00139 (31.7%)<0.00128 (31.5%)<0.001Cardiac manifestations6 (4.2%)2 (1.5%)0.0832 (1.6%)0.08300.157Intestinal manifestations10 (7.0%)1 (0.7%)0.0054 (3.3%)0.0593 (3.4%)0.059Renal manifestations5 (3.5%)3 (2.2%)0.41400.0461 (1.1%)0.317Neurological manifestations36 (25.4%)22 (16.3%)0.01218 (14.6%)0.00310 (11.2%)0.035Figure 1.Changes in BVASFigure 2.Steroid treatmentConclusion:MEPO effectively controlled systemic and respiratory EGPA symptoms in a large European cohort, with no major safety concerns.References:[1]Wechsler et al.

Abstract
Abstract
Background
The benefit of percutaneous mitral valve repair with mitraclip (PMVR) in patients with secondary mitral regurgitation (MR) is still debated.
Methods
In order to compare the outcome of PMVR with optimal medical therapy (OMT) versus OMT alone in patients with secondary MR, we performed a systematic review and meta-analysis of 2 randomized clinical trials (RCT) and 7 non-randomized observational studies (nROS). Hazard ratios (HR) and 95% confidence intervals (CI) were pooled through inverse variance random-effect model to compute the summary effect size for all-cause mortality, cardiovascular death and cardiac-related hospitalization. Subgroup and meta-regression analysis were also performed.
Results
An overall population of 3,118 individuals (67% men; mean age, 73 years) was included: 1,775 PMVR+OMT and 1,343 OMT patients, with mean follow-up of 24±15 months. PMVR+OMT was associated with a lower risk of all-cause death (HR: 0.77; 95% CI: 0.68–0.87), cardiovascular death (HR: 0.55; 95% CI: 0.34–0.89) and cardiac-related hospitalization (HR: 0.77; 95% CI: 0.64–0.92). Meta-regression analysis showed that larger left ventricular end-diastolic volume index (LVEDVI) portends higher mortality after PMVR (p<0.001).
Conclusions
This study-level meta-analysis shows that PMVR+OMT is associated with reduced all-cause death, cardiovascular death and cardiac-related hospitalization when compared with OMT alone in secondary MR. LVEDVI is a predictive marker of efficacy, as patients with smaller LVEDVI derive the largest benefit from PMVR.

Abstract
Abstract
Aims
The Acute Cardiac Care Association (ACCA)–European Association of Percutaneous Coronary Intervention (EAPCI) Registry on ST-elevation myocardial infarction (STEMI) of the EurObservational programme (EORP) of the European Society of Cardiology (ESC) registry aimed to determine the current state of the use of reperfusion therapy in ESC member and ESC affiliated countries and the adherence to ESC STEMI guidelines in patients with STEMI.
Methods and results
Between 1 January 2015 and 31 March 2018, a total of 11 462 patients admitted with an initial diagnosis of STEMI according to the 2012 ESC STEMI guidelines were enrolled. Individual patient data were collected across 196 centres and 29 countries. Among the centres, there were 136 percutaneous coronary intervention centres and 91 with cardiac surgery on-site. The majority of centres (129/196) were part of a STEMI network. The main objective of this study was to describe the demographic, clinical, and angiographic characteristics of patients with STEMI. Other objectives include to assess management patterns and in particular the current use of reperfusion therapies and to evaluate how recommendations of most recent STEMI European guidelines regarding reperfusion therapies and adjunctive pharmacological and non-pharmacological treatments are adopted in clinical practice and how their application can impact on patients’ outcomes. Patients will be followed for 1 year after admission.
Conclusion
The ESC ACCA-EAPCI EORP ACS STEMI registry is an international registry of care and outcomes of patients hospitalized with STEMI. It will provide insights into the contemporary patient profile, management patterns, and 1-year outcome of patients with STEMI.

Obstructive sleep apnea syndrome and autonomic dysfunction. Auton Neurosci 2019; 221:102563.

Abstract
Autonomic nervous system (ANS) has been extensively explored in obstructive sleep apnea (OSA). Autonomic alterations in these patients have been described by means of several methods, evaluating ANS function both directly with microneurography and indirectly through baroreflex sensitivity (BRS, by the sequence method or the cross-spectral approach), heart rate variability analysis (HRV, both in the time and frequency domain) during sleep and wake, or conventional laboratory tests, including cold pressor test, hand grip test or measurement of urinary cathecolamine excretion. Several studies in OSA patients have shown ANS alterations, in particular sympathetic overactivity, both acutely during apnea events and chronically during the daytime, being both also involved in cardiovascular consequences of sleep disordered breathing. The association between OSA and sympathetic dysregulation suggests a dose response relationship between OSA severity and the degree of sympathetic overactivity and this association seems to be reversible as the treatment of OSA is implemented. Additionally ANS is involved in regulating visceral and humoral functions to maintain the body homeostasis and in reaction and adaptation to external and internal stressor stimuli. However, the vast majority of studies have focussed on cardiovascular alterations, which are easier to measure, somewhat neglecting the other functions regulated by ANS. More evidence is therefore needed to better characterize the impact that sleep disorder breathing may have on ANS both in the short and long term.

Use of complementary medicine among patients with allergic rhinitis: an Italian nationwide survey. Clin Mol Allergy 2019; 17:2. [PMID: 30804711 PMCID: PMC6373013 DOI: 10.1186/s12948-019-0107-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2018] [Accepted: 02/05/2019] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND A growing use of complementary alternative medicine (CAM) has been found in Europe as well in Italy for chronic diseases, including the allergic rhinitis. The study aims at investigating the prevalence and the pattern of use of CAM amongst patient with allergic rhinitis. METHODS A 12-item questionnaire was developed by a panel of experts and administered to patients with moderate/severe allergic rhinitis consecutively referring during the study time-frame to seven allergy clinics placed all around Italy. The items covered several topics including reason for choosing CAM, its clinical efficacy, schedule of treatment, costs, type of therapy. RESULTS Overall 359 questionnaires were analysed. 20% of patients declared CAM use. A significant correlation between the use of CAM and female sex (p < 0.01) and with a higher level of education (p < 0.01) was observed. CAM users were adults (36% in the range between 20 and 40 years and 32% between 41 and 60 years). Youngsters (< 20 years) (7%) and elderly (> 60) (25%) less frequently used CAM.The most used type of CAM was homoeopathy (77% of patients). 60% of users would recommend CAM despite a poor clinical efficacy according to 67% of them. CONCLUSIONS Although no evidence supports CAM efficacy and safety, the number of patients who relies on it is not negligible. As allergic rhinitis is not a trivial disease, the use of CAM as the only treatment for it should be discouraged at any level, but by general practitioner and specialist in particular.

Abstract
This study provides taxonomic and distributional data of bryozoan species from the Ross Sea area, mainly around Terra Nova Bay, based on specimens curated at the Italian National Antarctic Museum (MNA, Section of Genoa). Bryozoan specimens were collected at 75 different sampling stations in the Ross Sea and in the Magellan Strait, in a bathymetric range of 18-711 meters, during 13 expeditions of the Italian National Antarctic Research Program (PNRA) conducted between 1988 and 2014. A total of 282 MNA vouchers corresponding to 311 specimens and 127 morphospecies have been identified and included in the present dataset. 62% of the species were already reported for the Terra Nova Bay area, where most of the Italian samples come from, with a 35% of samples representing new records classified at the specific level, and 3% classified at the genus level. These new additions increase to 124 the total number of species known to occur in Terra Nova Bay. Four 3D-models of Antarctic bryozoans from the Ross Sea are also presented and will be released for research and educational purposes on the Museum website.

Glutathione/pH-responsive nanosponges enhance strigolactone delivery to prostate cancer cells. Oncotarget 2018; 9:35813-35829.

Abstract
Strigolactones (SLs) are carotenoid-derived plant hormones that exhibit anti-cancer activities. We previously demonstrated that two SL analogues, MEB55 and ST362, inhibit the growth and survival of various cancer cell lines. However, these compounds have low aqueous solubility and stability at physiological pH. Here, we generated SL-loaded glutathione/pH-responsive nanosponges (GSH/pH-NS) to selectively deliver SLs to prostate cancer cells and enhance their therapeutic efficacy. The SLs were readily incorporated into the GSH/pH-NS. The drug loading efficiency was 13.9% for MEB55 and 15.4% for ST362, and the encapsulation efficiency was 88.7% and 96.5%, respectively. Kinetic analysis revealed that release of MEB55 and ST362 from the GSH/pH-NS was accelerated at acidic pH and in the presence of a high GSH concentration. Evaluation of the effects of MEB55- and ST362-loaded GSH/pH-NS on the growth of DU145 (high GSH) and PC-3 (low GSH) prostate cancer cells revealed that the GSH/pH-NS inhibited the proliferation of DU145 cells to a greater extent than free MEB55 or ST362 over a range of concentrations. These findings indicate GSH/pH-NS are efficient tools for controlled delivery of SLs to prostate cancer cells and may enhance the therapeutic efficacy of these compounds.

Abstract
Summary We performed a multicentre survey about the role of mobile apps in allergic respiratory diseases. The main objective was to investigate the current use and usefulness of mobile phone apps in the management of allergic respiratory disease. An original questionnaire including 12 multiple-choice questions was administered to 360 participants (153 male and 207 female subjects). Of notice, 290 subjects owned a smartphone, 120 a personal computer and 68 a tablet (multiple answers were possible). 123 subjects reported to be regular mobile-apps users, 209 were occasional users and 76 has never downloaded an app. Indeed, 259 subjects have never dealt with a medical or healthcare app, with only 8 subjects answering to often take advantage of such supportive tools. Data were even more discouraging when asking whether subjects had ever downloaded an app directly related to their own medical condition (allergy, asthma and rhinitis). 87.2% provided a negative answer. Among the few individuals who reported a previous experience with allergy/asthma apps only 2 subjects reported to regularly use the apps they had downloaded, even after months. The majority of subjects believed the apps would provide a relevant support, but only 25/360 participants found that the apps are "truly helpful", while 44 considered them of "help but not essential". Our data seem to show that the apps in the medical field, especially for allergic respiratory diseases, are welcome by patients, but their continued use and utility wane with the passage of time from the date of the download. In the future it will therefore be important to focus on the quality of the apps themselves and on the careful selection of the most suitable patients to use them. Finally, it will be important to make use of the fundamental contribution of healthcare professionals for the development of the apps.

Abstract
In this paper, we synthesized and evaluated the biological activity of structural analogues of natural strigolactones in which the butenolide D-ring has been replaced with a γ-lactam. The key step to obtain the α,β-unsaturated-γ-lactam was an RCM on suitably substituted amides. Strigolactones (SLs) are plant hormones with various developmental functions. As soil signaling chemicals, they are required for establishing beneficial mycorrhizal plant/fungus symbiosis. Beside these auxinic roles, recently SLs have been successfully investigated as antitumoral agents. Peculiar to the SL perception system is the enzymatic activity of the hormone receptor. SARs data have shown that the presence of the butenolide D-ring is crucial to retain the biological activity. The substitution of the butenolide with a lactam might shed light on the mechanism of perception. In the following, a dedicated in silico study suggested the binding modes of the synthesized compounds to the receptor of SLs in plants.

Abstract
Aims and background To evaluate the performance and feasibility of screening for prostate cancer by comparing screening modalities. Methods Prospective study of two comparable cohorts of healthy resident males aged 60 to 75 years. Screening attenders in the two invited cohorts were screened either by digital rectal examination (DRE) and transrectal ultrasonography (TRUS), or by serum prostate-specific antigen determination (PSA: cutoff 4 ng/ml). Attendance and biopsy rates, predictive values, prevalence of screen-detected cancers, as well as screening costs were determined, and the efficiency of the two screening modalities was compared. Results 1425 subjects were screened by DRE + TRUS. Attendance rate was 33.7%, the biopsy rate was 2.7%, and the prevalence of detected cancers was 1.82%. A total of 1315 subjects was screened by PSA. Attendance rate was 66.9%, the biopsy rate was 2.8%, and the prevalence of detected cancers was 1.67%. Screen-detected cancer stage was more favorable than observed in clinical practice, and early detection was evident, with the prevalence/incidence ratio higher than 10:1 in both programs. The cost per subject screened was about 34,000 Lire for DRE + TRSU and about 30,000 Lire for PSA program. Conclusions The study confirms that early detection of prostate cancer is possible and that screening is practically feasible. Both screening modalities achieved comparable results as regards early detection, but screening by PSA had a higher compliance and lower costs. PSA seems the ideal test to be used in prospective controlled studies aimed at demonstrating screening efficacy.

Abstract
Strigolactones (SLs) are plant hormones with various functions in development, responses to stress, and interactions with (micro)organisms in the rhizosphere, including with seeds of parasitic plants. Their perception for hormonal functions requires an α,β-hydrolase belonging to the D14 clade in higher plants; perception of host-produced SLs by parasitic seeds relies on similar but phylogenetically distinct proteins (D14-like). D14 and D14-like proteins are peculiar receptors, because they cleave SLs before undergoing a conformational change that elicits downstream events. Structure-activity relationship data show that the butenolide D-ring is crucial for bioactivity. We applied a bioisosteric approach to the structure of SLs by synthetizing analogues and mimics of natural SLs in which the D-ring was changed from a butenolide to a lactam and then evaluating their bioactivity. This was done by using a novel bioassay based on Arabidopsis transgenic lines expressing AtD14 fused to firefly luciferase, in parallel with the quantification of germination-inducing activity on parasitic seeds. The results obtained showed that the in planta bioassay is robust and quantitative, and thus can be confidently added to the SL-survey toolbox. The results also showed that modification of the butenolide ring into a lactam one significantly hampers the biological activity exhibited by SLs possessing a canonical lactonic D-ring.

Abstract
The study offers a retrospective analysis of the positive predictive value (PPV) of several variables, i.e. digital rectal examination (DRE), transrectal ultrasonography (TRUS), PSA value, PSA density (PSAD), and free/total PSA ratio (F/T), for the histologic outcome of 179 prostate biopsies performed within a population-based screening trial. The ratio of spared benign biopsies to missed cancers (SBB/MC) if biopsy results had been decided on the basis of single variables was also evaluated. PPV was 82.9% for DRE, 56.3% for TRUS, 26.6% for PSA (cutoff ≥4 ng/mL), 47.4% for PSA (cutoff ≥10 ng/mL), 42.0% for PSAD (cutoff 0.15), 59.2% for PSAD (cutoff 0.20), 34.9% for F/T (cutoff 0.20) and 40.0% for F/T (cutoff 0.15). SBB/MC was 121/23 for DRE, 96/12 for TRUS, 11/10 for PSA (cutoff ≥4 ng/mL), 107/34 for PSA (cutoff ≥10 ng/mL), 87/23 for PSAD (cutoff 0.15), 109/26 for PSAD (cutoff 0.20), 45/8 for F/T (cutoff 0.20) and 70/14 for F/T (cutoff 0.15). Multivariate analysis of the association with biopsy outcome showed the highest odds ratio for TRUS (13.24, 95% CI=4.4–30.7), and considerably lower values for DRE (4.17, 95% CI=2.0–8–9), PSAD (cutoff 0.20: 3.24, 95% CI=–1.8–5.7) and F/T (cutoff <0.15: 3.16, 95% CI =1.7–1.8). None of the possible variable combinations was clinically useful: the highest PPV (83.3%) was obtained with a combination of suspicious DRE/TRUS, PSAD >0.20 and F/T <0.15, which nevertheless missed 20 of 52 cancers.

Abstract
Background The query "are there animals at home?" is usually administered for collecting information on anamnesis. This modality to consider exposure to pet allergens constitutes a potential bias in epidemiological studies and in clinical practice. The aim of our study was to evaluate/quantify different modalities of exposure to cat/dog in inducing allergic sensitization. Methods Thirty Italian Allergy units participated in this study. Each centre was required to collect the data of at least 20 consecutive outpatients sensitized to cat/dog allergens. A standardized form reported all demographic data and a particular attention was paid in relieving possible modalities of exposure to cat/dog. Results A total 723 patients sensitized to cat/dog were recorded, 359 (49.65%) reported direct pet contact, 213 patients (29.46%) were pet owners, and 146 subjects (20.19%) were exposed to pets in other settings. Other patients were sensitized by previous pet ownership (150-20.75%) or indirect contact (103-14.25%), in 111 subjects (15.35%) any contact was reported. Conclusions Only 213 patients (29.46%) would be classified as "exposed to animals" and 510 (70.54%) as "not exposed" according to usual query. Our classification has shown that many "not-exposed" subjects (399-55.19%) were "really exposed". The magnitude of exposure to pet allergens at home is not related exclusively to pet ownership. These considerations should be taken into account during the planning of epidemiological studies and in clinical practice for the management of pet allergic individuals.

Abstract
The study purpose was to assess PSA velocity (PSAV) in healthy subjects in order to establish a reliable cutoff for the differential diagnosis of prostate cancer in a screening setting. We studied a series of 1666 healthy men aged 55 to 74 years undergoing two total PSA determinations at a four-year interval within a population-based randomized screening trial at the Centro per lo Studio e la Prevenzione Oncologica of Florence. First and second screening round PSA assays (PSA1 and PSA2) were carried out with the same method and by the same laboratory. PSAV (PSA1–PSA2/year) was determined in non-cancer subjects in the overall series or in specific age and PSA subgroups, and in subjects with cancer detected at the second screening round. Average PSAV in 1648 non-cancer subjects was 0.07 ng/mL/year (range −2.18+5.99, 95% CI 0.05–0.09); at least one third of subjects showed a decrease in PSA (negative PSAV), mostly of limited magnitude and in the low PSA range. Average PSAV in the 18 cancer patients was 1.16 ng/mL/year (range 0.10–5.6, 95% CI 0.56–1.77), which is significantly higher (p<0.01) than in non-cancer subjects. None of the cancer patients showed a PSA decrease over time. Whatever cutoff was taken for PSAV, its power to discriminate cancer was limited: in particular the previously used PSAV cutoff of 0.75 ng/mL/year would have included only 42 of the 1648 non-cancer subjects (specificity 97.5%) but excluded eight of the 18 cancer patients (sensitivity 55.5%). At best, with the adopted screening protocol PSAV (cutoff 0.10 ng/mL/year) could have spared 27.9% of non-cancer subjects with PSA ≥2.5 ng/mL further diagnostic assessment and 22.7% of non-cancer subjects with PSA ≥4 ng/mL random sextant biopsy, while missing no cancers. This study provides a reliable estimate of PSAV based on a large unbiased population sample. PSAV is widely variable over time, particularly at low PSA values. PSAV might be of value as an indicator for diagnostic assessment and random sextant biopsy in a screening setting.

Abstract
The free-to-total prostate-specific antigen ratio (F/T PSA) is associated with the presence of prostate cancer and is thus used as an indicator for suspicion of prostate cancer and as a determinant for biopsy. We reviewed a recent retrospective series of 966 consecutive prostate biopsies where F/T PSA was blindly determined and did not influence biopsy indication. We simulated the association of F/T PSA with biopsy outcome and its impact as a biopsy determinant. When adopting an F/T PSA cutoff of 10%, 13%, 16% or 20% among random sextant biopsies in the 4–10 ng/mL total PSA range, the sensitivity was 15%, 37%, 55% and 72% and the specificity 89%, 80%, 64% and 44%, respectively. Using F/T PSA as a biopsy determinant, from 1.7 to 2.6 cancer biopsies would have been delayed to avoid 10 benign biopsies. As this balance is not acceptable, F/T PSA has no role as a biopsy indicator and its clinical use is questionable.

Abstract
Summary
Objectives: To investigate the effects of hypoxia during sleep on linear and self-similar components of heart rate variability (HRV) in eight healthy subjects at high altitude on Mount Everest.
Methods: ECG was monitored by using an innovative textile-based device, the MagIC system. For each subject three night recordings were performed at sea level (SL), at 3500 m and 5400 m above SL. RR Interval (RRI) was derived on a beat-by-beat basis from the ECG and the VLF, LF and HF spectral components and the LF/HF ratio were estimated. Short-(α1) and long-term (α2) scale exponents as well as the recently proposed spectrum of self-similarity coefficients, α(n) were estimated by detrended fluctuation analysis (DFA).
Results: With respect to SL, all HRV parameters but one (α2) were significantly modified at 3500 m. However, at 5400 m they tended to return to the SL values and this was in contrast with the increase in the hypobaric hypoxia and in the number of central sleep apneas occurring at higher altitude. The only HRV index that displayed changes at 5400 m was the DFA α(n) spectrum, with α(n) values significantly lower than at SL for 20 < n < 50 and higher for 200 < n < 400, being n the box size..
Conclusions: While the biological interpretation of these results is still in progress, our data indicates that the cardiac response to high altitude hypoxia during sleep can hardly be fully explored by traditional HRV estimators only, and requires the additional support of more sophisticated indexes exploring also nonlinear and fractal features of cardiac variability.

Abstract
Aim To assess the validity of PSA doubling time (PSADT) as a predictor of prostate sextant biopsy outcome in patients with PSA levels in the 4–10 ng/mL range. Material and methods A consecutive series of 355 sextant biopsies performed during 2001–2007 in subjects with negative digital rectal examination and transrectal ultrasonography was considered. Variables tested as possible predictors were age, total and free/total PSA value, PSA velocity and PSA doubling time. While PSA at time of biopsy and free/total PSA were determined with a standardized method undergoing strict quality control, previous PSA values used to assess velocity/doubling time came from other labs using different assays over widely varying intervals of time. The association with biopsy outcome (cancer vs non-cancer) was investigated by univariate and multivariate analysis. Results Apart from free/total PSA ratio, no other studied variable showed a statistically significant and independent association with biopsy outcome, either at univariate or multivariate analysis. No studied variable had a good performance as a biopsy indicator. Depending on the variable considered, 1.17 to 1.97 cancers would be missed to spare 10 benign biopsies. Conclusion When based on PSA data determined with different assays over widely varying intervals and in the absence of an underlying protocol for PSA surveillance, PSA velocity and doubling time should never discount a biopsy prompted by total PSA elevation.

Abstract
Rhinitis and sinusitis usually coexist and are concurrent in most individuals; thus, the correct terminology is now "rhinosinusitis". On the basis of numerous causative factors, often co-existing in the same patient, the diagnosis of rhinosinusitis is also made by a wide variety of practitioners (allergologists, otolaryngologists, pulmonologists, primary care physicians, paediatricians, and many others). Approximately 5-15% of the population suffers from chronic rhinosinusitis, and in 10-12% of them, it is of dental origin. The treatment of odontogenic maxillary sinus disease is directed to the management of the rhinosinusitis and of the odontogenic source. The widespread use of dental implants and reconstructive procedures for dental implant placement has led to new types of complication, as in this case report, due to chronic eosinophilic rhinosinusitis secondary to Fusarium infection in the maxillary sinus. The patient was initially evaluated by the allergologist, and subsequently successfully treated by the otolaryngologist with Functional Endoscopic Sinus Surgery. The advantages of endoscopic sinus surgery include more accurate visualization, no external incision, reduced soft tissue dissection, and reduced hospital stay. Chronic maxillary sinusitis of dental origin is a common disease that requires treatment of the sinusitis as well as of the odontogenic source.

Low pH conditions impair module capacity to regenerate in a calcified colonial invertebrate, the bryozoan Cryptosula pallasiana. MARINE ENVIRONMENTAL RESEARCH 2017; 125:110-117.

Abstract
Many aquatic animals grow into colonies of repeated, genetically identical, modules (zooids). Zooid interconnections enable colonies to behave as integrated functional units, while plastic responses to environmental changes may affect individual zooids. Plasticity includes the variable partitioning of resources to sexual reproduction, colony growth and maintenance. Maintenance often involves regeneration, which is also a routine part of the life history in some organisms, such as bryozoans. Here we investigate changes in regenerative capacity in the encrusting bryozoan Cryptosula pallasiana when cultured at different seawater pCO2 levels. The proportion of active zooids showing polypide regeneration was highest at current oceanic pH (8.1), but decreased progressively as pH declined below that value, reaching a six-fold reduction at pH 7.0. The zone of budding of new zooids at the colony periphery declined in size below pH 7.7. Under elevated pCO2 conditions, already experienced sporadically in coastal areas, skeletal corrosion was accompanied by the proportional reallocation of resources from polypide regeneration in old zooids to the budding of new zooids at the edge of the colony. Thus, future ocean acidification can affect colonial organisms by changing how they allocate resources, with potentially profound impacts on life-history patterns and ecological interactions.

Abstract
Background. During the two last decades, the interest in the role of Vitamin D (VD) in allergic disease has increased. Apart from the well-known actions of VD in bone metabolism, recent studies suggested its possible role as an immune-modulator in allergy. Objective. This study, conducted over the Italian territory, evaluated the possible correlations between VD serum level and diagnosed allergic diseases (rhinitis / asthma, food allergy, atopic dermatitis). Thus, VD was assessed in patients with physician-diagnosed allergic diseases. Methods. The study was carried out in hospital- and private practice-based setting between October 2012 and March 2013, and 18 Centers participated. Only adult patients, with at least one positive skin prick test were included. The diagnostic procedures and the data collection were standardized among the centers. VD levels were assayed by the same laboratory test. Results. Three hundred and nine patients were enrolled (132 male, mean age 37.5 ± 17 years). Of them, 40% reported a positive family history for allergies (asthma / rhinitis). Rhinitis plus asthma was present in 47% of patients, atopic dermatitis in 15%, and a consistent clinical history of food allergy associated with positive skin tests was present in 25% of subjects. There was no significant association between VD level and age, sex, family history, rhinitis, or food allergy. VD levels were overall lower in patients with asthma and rhinitis, but without statistical significance. A significant difference in VD levels was detected between patient with or without atopic dermatitis. VD was not related to seasonal allergens, whereas a significant negative correlation was seen for house dust mite and dog dander. Conclusion. Our data, derived from a cross-sectional study involving only allergic patients, agree partially with the current literature. Nonetheless, the association between VD levels and allergies appeared weak. Studies involving larger samples would be required to better define the association between VD and allergies.

Abstract
Heart failure (HF) affects approximately 1-2 % of the adult population. Diabetes mellitus (DM) is one of the most frequent comorbidities in HF, portending a worse prognosis. DM is associated with an increased risk of artery disease, and consequently of post-ischemic HF, but it may also alter directly the myocardial structure and function. Insights into the pathophysiological mechanisms of diabetic cardiomyopathy have been provided by both experimental and clinical investigations. In recent years, it has emerged that the fibrotic process is a result of the convergence of multiple neurohormonal alterations in diabetic cardiomyopathy at the basis of disease progression and phenotype determination: HF with reduced or preserved ejection fraction. Therapies for HF and DM should demonstrate an improved prognosis and have a neutral effect on glucose homeostasis and the risk of HF development.
