The management of both acute and chronic cough requires a systematic and comprehensive approach. Despite the approved protocols for management, the pediatric assessment of cough and the corresponding prescribing attitude frequently do not fit these protocols, which can be affected by parental suggestions – sometimes substantially. Objective: The objective of this study was to investigate both the perception and the behavior of a representative sample of Italian pediatricians toward cough in real life. Methods: A specific questionnaire consisting of 18 questions was prepared. The questionnaire was completed by 300 pediatricians (all members of PAIDOSS: Italian National Observatory on Health of Childhood and Adolescence) who represented ~300,000 children. Results: A vast majority of children have cough throughout the year (99.3% of respondents have cough during autumn/winter and 64.7% in spring/summer). Allergic disease is the most frequent suspected cause of chronic cough in children (53%), and this is supported by the high demand for consultations: 73% seek the opinion of allergologists, 62% of otorhinolaryngologists and only 33% of pulmonologists. The majority of pediatricians (92%) reported that they prescribe therapy in acute cough regardless of cough guidelines. Moreover, the survey pointed out the abuse of aerosol therapy (26% in acute cough and 38% in chronic cough) and of antibiotics prescription (22% in acute cough and 42% in chronic cough). Conclusion: Our survey suggests that some Italian pediatricians’ therapeutic attitudes should be substantially improved in order to achieve better management of cough in children and to minimize the burden of cough.

Background: Peach gibberellin-regulated protein (peamaclein) has recently emerged as a relevant food allergen in cypress pollen-hypersensitive patients. Objective: We looked for mono-sensitization to peamaclein among Italian cypress-pollen allergic patients. Material and methods: 835 cypress pollen hypersensitive patients from 28 Italian allergy centers under went thorough interview for food-allergic reactions, and SPT with a commercial peach extracts containing peamaclein. In peach reactors, IgE to rPru p 3 was measured, and those scoring negative were enrolled as potentially mono-sensitized to peamaclein. IgE reactivity to rPru p 7 was evaluated by immunoblot and by an experimental ImmunoCAP with rPru p 7. Results: Peach SPT scored positive in 163 (19.5%) patients but 127 (77,9%) were excluded because Pru p 3 reactors. Twenty-four (14,7%, corresponding to 2.8% of the entire study population) were considered as potentially mono-sensitized to peamaclein. Their distribution did not show any geographic preference. Seventeen/24 (70,8%) had a history of food allergy, in most cases (n=15) to peach. Other offending foods included other Rosaceae, citrus fruits, fig, melon, tree nuts, and kiwi. On peach immunoblot, only 3/18 putative peamaclein allergic subjects reacted to a band at about 7kDa; 4 other patients reacted at about 50-60 kDa. Ten/18 (56%) scored positive for Pru p 7 on ImmunoCAP. Conclusion: Peamaclein allergy and sensitization prevalence seem rare in Italy. Most patients react to peach, albeit other Rosaceae fruits and several citrus fruits may also act as offending foods. Peach and cypress pollen probably share also cross-reacting allergens other than peamaclein.

Aim. Since the efficacy of antibiotics in the management of cough from upper respiratory tract infections (URTI) is unclear, we conducted an observational study to evaluate the efficacy of antibiotic compared to symptomatic treatment in adults with productive cough from URTI in a real life setting. Methods. One-hundred and 50 subjects presenting to five general practice ambulatories with productive cough due to URTI were included in the study. According to the physician judgment, patients were treated with either oral antibiotics (group A, 50 patients), a mucoactive syrup (sobrerol: group S, 50 patients) as symptomatic treatment, or both sobrerol and oral antibiotics (group SA, 50 patients). Cough severity was assessed daily with a diary, by means of a validated verbal category-descriptive (VCD) Scale. Results. In every treatment group cough severity decreased over time (P

Cough severity was assessed daily with a diary, by means of a validated verbal category-descriptive (VCD) Scale. Results. In every treatment group cough severity decreased over time (P<0.001); however, during the first week of treatment patients in groups S and SA experienced significantly lower VCD score values in comparison to Group A (P=0.045 and P=0.010, respectively). On the other hand, the VCD score was never significantly different between the two groups that received symptomatic treatment at any of the 4 weeks of the study, suggesting that the effect observed was due to the action of the mucoactive syrup. Conclusion. Our data confirm the lack of efficacy of antibiotics in the management of productive cough in URTI and suggest that symptomatic treatment should be preferred to antibiotics in acute cough from URTI.

- Abstract
Modern automation systems shall be able to conjugate increasing complexity of controlled processes with agile production reconfiguration requirements. In such a context, structured design approaches based on formal reference models as well as integrated verification and validation process, have to be adopted. To such an aim, present paper proposes an approach based on Model- Checking methods and tools oriented to the Verification of logic control systems in the field of Industrial Automation. In particular, graphical Stateflow based model deployment, Bounded Model Checking techniques and Model Coverage properties have been considered. Furthermore, the proposed approach have been applied regarding the development of the control solution for an automatic warehouse system integrated into a flexible shoes manufacturing plant.

- Abstract
Cough is a frequent symptom associated to upper respiratory tract infections (URTIs) and, although being self-limiting, it might deeply affect the quality of life. Homeopathic products are often employed by patients to treat cough, but the evidence on their efficacy is scarce. Thus, we tested the efficacy of a homeopathic syrup in treating cough arising from URTIs with a randomized, double blind, placebo controlled clinical trial.Patients were treated with either the homeopathic syrup or a placebo for a week, and recorded cough severity in a diary by means of a verbal category-descriptive score for two weeks. Sputum viscosity was assessed with a viscosimeter before and after 4 days of treatment; patients were also asked to provide a subjective evaluation of viscosity.Eighty patients were randomized to receive placebo (n = 40) or the homeopathic syrup (n = 40). All patients completed the study. In each group cough scores decreased over time, however, after 4 and 7 days of treatment, cough severity was significantly lower in the homeopathic group than in the placebo one (p < 0.001 and p = 0.023, respectively). Sputum was collected from 53 patients: in both groups its viscosity significantly decreased after 4 days of treatment (p < 0.001); however, viscosity was significantly lower in the homeopathic group (p = 0.018). Instead, the subjective evaluation did not significantly differ between the two groups (p = 0.059). No adverse events related to any treatment were reported.We concluded that the homeopathic syrup employed in the study was able to effectively reduce cough severity and sputum viscosity, thereby representing a valid remedy for the management of acute cough induced by URTIs

- Abstract
Increasingly universities in developed countries are engaging in transnational education. Responsibilities and opportunities to exercise management and leadership in the provision of transnational education depend on the organisational model adopted and whether the academics involved are on home or international campuses. Models range from neo-colonial control to transnational partnerships. In the Australian Office for Learning and Teaching study that informs this paper good practice in allocation and exercise of management and leadership responsibilities was identified and recommendations developed. A balance was struck between quality assurance obligations of the home institution, which imply a high level of home-based control, and the value of a degree of local control to the commitment of local academics involved, to their career opportunities, and to the educational experiences of their students.

- Abstract
Australian universities, like others in the education export market, face the imperative of global engagement. One means adopted is transnational education (TNE), defined here as an arrangement for provision of higher education where students acquire an award in one country, which has been issued by a higher education institution based in another country. As an Australia award it must meet Australian standards, including the Tertiary Education Quality and Standards Agency (TEQSA) requirements. At the same time transnational partners must meet local realities. These include national regulatory requirements, including requirements for self-accrediting institutions, and local professional body requirements. There are also educational and staffing reasons for adapting to local needs. In this paper we look at a range of models for balancing home institution and offshore partner interests in the offering of TNE. We examine how these sit with the TEQSA requirement that the higher education provider has effective mechanisms to manage and quality assure all aspects of the arrangement to ensure student learning outcomes ‘equivalent to’ those when a course of study is delivered by the higher education provider. The paper is informed by an Australian Office of Learning and Teaching project Learning without borders that investigated approaches to TNE, with particular reference to branch campuses, categorised models, and explored consequences for staff in leadership position in home and offshore locations, as well as consequences for the learning experiences of students offshore. The project recommended that, where institutions offer TNE programs through multiple providers or where programs or units are taught for the first time by a TNE provider, a high degree of home campus control may be appropriate. Where branch campuses have demonstrated capability and stability contextualisation of content, learning resources, learning and teaching activities, and assessment is recommended.

- Abstract
In transnational education the place – in both an organisational and a geographic sense – in which educational decisions are made impacts on the academics involved and on student learning. The subject of this paper is learning and accreditation that takes place outside a home university through offshore branch campuses. A case study of two Australian Universities with offshore campuses in Sarawak, Malaysia was undertaken. Policies and procedures were reviewed and an empirical study of the experiences of academics involved was conducted. The study focused on who makes decisions about curriculum content, learning and teaching activities, design and provision of educational resources, and the assessment of student work. Consequences of the organisational relationships for academics involved and for student learning are examined in this paper. On the basis of the study a high degree of local control is recommended, at least for units of study that have operated transnationally several times.

- Abstract
The establishment of higher educational hubs in Malaysia and Singapore has spurred the growth of transnational education (TNE) offerings in Asia, and attracted several Australian higher education providers to set up branch campuses in these countries. In Malaysia, TNE is seen as contributing to economic targets by helping to decrease the outflow of students and currency, and by attracting international students to Malaysian shores (British Council 2012). The provision of higher education through TNE raises issues somewhat distinct from those arising with local provision of higher education. These include the balance of local and foreign educational decision making and its implications for academic staff and for the learning experiences of students. This paper is informed by ‘Learning without Borders: Leadership in transnational education and internationalization of curriculum’, an Australian Office of Learning and Teaching (OLT) funded project undertaken at Curtin University and Swinburne University of Technology, involving Australian campuses and branch campuses. The project investigated staff experiences, expectations and preferences on TNE issues including career path opportunities, teaching and learning implications. The project focused particularly on the development of recognition and support for leadership roles in transnational education and on internationalization of curriculum. The paper highlights some of the TNE and internationalization measures that might enhance staff experiences and student learning.

The pathways of lead (Pb(2+)) uptake were studied in fura-2-loaded cerebellar granule cells from 8-day-old rats. In a nominal Ca-free external bath, Pb(2+) (5-50 microM) determined an increase of the fluorescence emission ratio (R = E(340)/E(380)) even in the absence of any specific stimulus. This rise was dose-dependent, was not significantly affected by mM Mg(2+) or Ca(2+), but it was readily reversed by the membrane-permeant heavy metal chelator tetrakis(2-pyridylmethyl) ethylene-diamine (TPEN, 100 microM), indicating that it was due to Pb(2+) influx. The rate of rise, dR/dt, was increased up to a factor of 5 by depolarizing high-KCl solution, indicating a sizeable permeation through voltage-dependent channels. This effect was neither antagonized by nimodipine, nor enhanced by BayK8644, but it was slackened by omega-agatoxin IVA (200 nM), suggesting an involvement of non-L-type calcium channels. Pb(2+) influx was also stimulated by glutamic acid or NMDA in the presence of 10-30 microM glycine, but only in Mg-free solution, suggesting that glutamate channels of the NMDA type are an additional pathway of Pb(2+) uptake. Pb(2+) caused a time-, dose- and stimulus-dependent saturation of the dye, whose intracellular concentration is approximately 10 microM, indicating that intracellular Pb(2+) can readily reach a concentration in the micromolar range. These results indicate that the particular vulnerability of neurones to Pb(2+) poisoning is linked to the presence of specific transport systems, which mediate the rapid uptake of Pb(2+) into the neurone.

- Abstract
Under ‘National Protocols’ established for higher education Australian universities are required to meet a consistent set of standards “regardless of whether its higher education students are located in Australia or offshore.” (MCEETYA, 2007, p.2). In this context we report in this paper approaches to curriculum and assessment decision-making encountered in an investigation of transnational education and internationalisation. The investigation is a component of the Australian Learning and Teaching Council (ALTC) project ‘Learning without borders: Linking development of transnational leadership roles to international and cross-cultural teaching excellence’; a project conducted by Curtin University and Swinburne University of Technology in Australia and in Sarawak. Meeting the same criteria specified in the National Protocols onshore and offshore can be and is addressed in different ways, even within the same higher education institution. In this paper we distinguish four approaches to curriculum decision-making designed to ensure the same standards are met. These may be styled: (a) home campus curriculum control, (b) limited branch campus learning, teaching and assessment contextualisation, (c) substantial branch campus learning, teaching and assessment contribution constrained by a requirement to attain the same learning outcomes, and (d) branch campus curriculum design. The locus of control varies between these approaches with implications for both the student experience and the professional experience and responsibilities of staff.

- Abstract
Item does not contain fulltext, This work completes previous findings and, using cysteine scanning mutagenesis (CSM) and biochemical methods, provides detailed analysis of conformational changes of the S6 domain and C-linker during gating of CNGA1 channels. Specific residues between Phe375 and Val424 were mutated to a cysteine in the CNGA1 and CNGA1(cys-free) background and the effect of intracellular Cd(2+) or cross-linkers of different length in the open and closed state was studied. In the closed state, Cd(2+) ions inhibited mutant channels A406C and Q409C and the longer cross-linker reagent M-4-M inhibited mutant channels A406C(cys-free) and Q409C(cys-free). Cd(2+) ions inhibited mutant channels D413C and Y418C in the open state, both constructed in a CNGA1 and CNGA1(cys-free) background. Our results suggest that, in the closed state, residues from Phe375 to approximately Ala406 form a helical bundle with a three-dimensional (3D) structure similar to those of the KcsA; furthermore, in the open state, residues from Ser399 to Gln409 in homologous subunits move far apart, as expected from the gating in K(+) channels; in contrast, residues from Asp413 to Tyr418 in homologous subunits become closer in the open state.

- Abstract
Item does not contain fulltext, We investigated conformational changes occurring in the C-linker and cyclic nucleotide-binding (CNB) domain of CNGA1 channels by analyzing the inhibition induced by thiol-specific reagents in mutant channels Q409C and A414C in the open and closed state. Cd(2+) (200 microM) inhibited irreversibly mutant channels Q409C and A414C in the closed but not in the open state. Cd(2+) inhibition was abolished in the mutant A414C(cys-free), in the double mutant A414C + C505T and in the tandem construct A414C + C505T/CNGA1, but it was present in the construct A414C + C505(cys-free). The cross-linker reagent M-2-M inhibited mutant channel Q409C in the open state. M-2-M inhibition in the open state was abolished in the double mutant Q409C + C505T and in the tandem construct Q409C + C505T/CNGA1. These results show that C(alpha) of C505 in the closed state is located at a distance between 4 and 10.5 A from the C(alpha) of A414 of the same subunit, but in the open state C505 moves towards Q409 of the same subunit at a distance that ranges from 10.5 to 12.3 A from C(alpha) of this residue. These results are not consistent with a 3-D structure of the CNGA1 channel homologous to the structure of HCN2 channels either in the open or in the closed state.

- Abstract
Item does not contain fulltext, Three constructs are used for the analysis of biophysical properties of CNGA1 channels: the WT CNGA1 channel, a CNGA1 channel where all endogenous cysteines were removed (CNGA1cys-free) and a construct composed of two CNGA1 subunits connected by a small linker (CNGA1tandem). So far, it has been assumed, but not proven, that the molecular structure of these ionic channels is almost identical. The I/V relations, ionic selectivity to alkali monovalent cations, blockage by tetracaine and TMA+ were not significantly different. The cGMP dose response and blockage by TEA+ and Cd2+ were instead significantly different in CNGA1 and CNGA1cys-free channels, but not in CNGA1 and CNGA1tandem channels. Cd2+ blocked irreversibly the mutant channel A406C in the absence of cGMP. By contrast, Cd2+ did not block the mutant channel A406C in the CNGA1cys-free background (A406Ccys-free), but an irreversible and almost complete blockage was observed in the presence of the cross-linker M-4-M. Results obtained with different MTS cross-linkers and reagents suggest that the 3D structure of the CNGA1cys-free differs from that of the CNGA1 channel and that the distance between homologous residues at position 406 in CNGA1cys-free is longer than in the WT CNGA1 by several Angstroms.

The current work outlines a comprehensive development approach to support the realisation of innovative reconfigurable factory control software from the preliminary design to its deployment in the shop floor. The proposed method consists of three major steps: control conceptual design, application development and evaluation of solution robustness. The innovation features of the proposed control development approach rely upon the integration of reconfiguration policies in the distributed automation infrastructures based on standard IEC 61499. The benefits of the proposed approach have been assessed with regard to an industrial application dealing with the manufacturing of personalised footwear goods. [ABSTRACT FROM PUBLISHER]

LEAD , *NEURONS , *GLUTAMIC acid , *ABSORPTION - Abstract
The pathways of lead (Pb[sup 2+]) uptake were studied in fura-2-loaded cerebellar granule cells from 8-day-old rats. In a nominal Ca-free external bath, Pb[sup 2+] (5–50 µm) determined an increase of the fluorescence emission ratio (R = E[sub 340]/E[sub 380]) even in the absence of any specific stimulus. This rise was dose-dependent, was not significantly affected by mm Mg[sup 2+] or Ca[sup 2+], but it was readily reversed by the membrane-permeant heavy metal chelator tetrakis(2-pyridylmethyl) ethylene-diamine (TPEN, 100 µm), indicating that it was due to Pb[sup 2+] influx. The rate of rise, dR/dt, was increased up to a factor of 5 by depolarizing high-KCl solution, indicating a sizeable permeation through voltage-dependent channels. This effect was neither antagonized by nimodipine, nor enhanced by BayK8644, but it was slackened by ω-agatoxin IVA (200 nm), suggesting an involvement of non-L-type calcium channels. Pb[sup 2+] influx was also stimulated by glutamic acid or NMDA in the presence of 10–30 µm glycine, but only in Mg-free solution, suggesting that glutamate channels of the NMDA type are an additional pathway of Pb[sup 2+] uptake. Pb[sup 2+] caused a time-, dose- and stimulus-dependent saturation of the dye, whose intracellular concentration is ∼ 10 µm, indicating that intracellular Pb[sup 2+] can readily reach a concentration in the micromolar range. These results indicate that the particular vulnerability of neurones to Pb[sup 2+] poisoning is linked to the presence of specific transport systems, which mediate the rapid uptake of Pb[sup 2+] into the neurone.

Electroacoustic music with its technological nature dictates a rethinking of traditional categories in music publishing. Concepts such as "work", "author", "instrument", "performer", even the very idea of "writing", all change and must be reconsidered alongside the medium, the carrier. The work I've being doing as a music publisher puts me in the position to choose among different solutions, in the attempt to reproduce and guarantee this interesting complexity. On the other hand, I also intend to introduce an order in this complexity, with the aim to salvage every single process of development, protection and valorisation of the works we are publishing. In my article I focus on the principles I'm following in my work, not so much to "domesticate" musical ideas into a fixed standard, but to free every work from its particularism -- especially from the dependence from technological devices and specific human agents (performers, collaborators). In the last part I discuss the work we are doing to publish a new, more efficient score of Prometeo. Tragedia dell'ascolto (1981-1985) by Luigi Nono. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19) is often associated with interstitial pneumonia. However, there is insufficient knowledge on the presence of autoimmune serological markers in patients with COVID-19. We analyzed the presence and role of autoantibodies in patients with COVID-19-associated pneumonia. We prospectively studied 33 consecutive patients with COVID-19, 31 (94%) of whom had interstitial pneumonia, and 25 age-matched and sex-matched patients with fever and/or pneumonia with etiologies other than COVID-19 as the pathological control group. All patients were tested for the presence of antinuclear antibodies (ANAs), anti-antiphospholipid antibodies, and anti-cytoplasmic neutrophil antibodies (ANCAs). Clinical, biochemical, and radiological parameters were also collected. Fifteen of 33 patients (45%) tested positive for at least one autoantibody, including 11 who tested positive for ANAs (33%), 8 who tested positive for anti-cardiolipin antibodies (immunoglobulin (Ig)G and/or IgM; 24%), and 3 who tested positive for anti-β2-glycoprotein antibodies (IgG and/or IgM; 9%). ANCA reactivity was not detected in any patient. Patients that tested positive for auto-antibodies had a significantly more severe prognosis than other patients did: 6 of 15 patients (40%) with auto-antibodies died due to COVID-19 complications during hospitalization, whereas only 1 of 18 patients (5.5%) who did not have auto-antibodies died (P=0.03). Patients with poor prognosis (death due to COVID-19 complications) had a significantly higher respiratory rate at admission (23 breaths per minute vs. 17 breaths per minute; P=0.03) and a higher frequency of auto-antibodies (86% vs. 27%; P=0.008). In conclusion, auto-antibodies are frequently detected in patients with COVID-19 possibly reflecting a pathogenetic role of immune dysregulation. However, given the small number of patients, the association of auto-antibodies with an unfavorable prognosis requires further multicenter studies.

Background Health-related quality of life (HRQoL) impairment is often reported among COVID-19 ICU survivors, and little is known about their long-term outcomes. We evaluated the HRQoL trajectories between 3 months and 1 year after ICU discharge, the factors influencing these trajectories and the presence of clusters of HRQoL profiles in a population of COVID-19 patients who underwent invasive mechanical ventilation (IMV). Moreover, pathophysiological correlations of residual dyspnea were tested. Methods We followed up 178 survivors from 16 Italian ICUs up to one year after ICU discharge. HRQoL was investigated through the 15D instrument. Available pulmonary function tests (PFTs) and chest CT scans at 1 year were also collected. A linear mixed-effects model was adopted to identify factors associated with different HRQoL trajectories and a two-step cluster analysis was performed to identify HRQoL clusters. Results We found that HRQoL increased during the study period, especially for the significant increase of the physical dimensions, while the mental dimensions and dyspnea remained substantially unchanged. Four main 15D profiles were identified: full recovery (47.2%), bad recovery (5.1%) and two partial recovery clusters with mostly physical (9.6%) or mental (38.2%) dimensions affected. Gender, duration of IMV and number of comorbidities significantly influenced HRQoL trajectories. Persistent dyspnea was reported in 58.4% of patients, and weakly, but significantly, correlated with both DLCO and length of IMV. Conclusions HRQoL impairment is frequent 1 year after ICU discharge, and the lowest recovery is found in the mental dimensions. Persistent dyspnea is often reported and weakly correlated with PFTs alterations. Trial registration NCT04411459.

Background Autoantibodies against-phospholipase A2 receptor (PLA2R) are specific markers of idiopathic membranous nephropathy (iMN). Enzyme-linked immunosorbent assay (ELISA) is becoming the preferred method in many laboratories for the determination of anti-PLA2R antibodies, because it provides quantitative results, and is not prone to subjective interpretation, as is the case with indirect immunofluorescence assay. Methods The purpose of our study was to determine the diagnostic performance of serum PLA2R antibodies detected by commercially available ELISA in a large Italian multicenter cohort of patients with biopsy-proven iMN and in patients with other renal diseases, with special focus on evaluating the optimal cut-off value to discriminate positive and negative results. A total of 495 consecutive patients were recruited. Renal biopsies were performed in all patients, and blood samples were taken before the initiation of immunosuppressive treatment. Results According to the clinical diagnosis and to kidney biopsy, 126 patients were diagnosed with iMN and 369 had other non-membranous nephropathies. Anti-PLA2R autoantibodies were detected using a commercial anti-PLA2R ELISA. At a cut-off value of 20 relative units (RU)/ml indicated by the manufacturer for positive classification, sensitivity was 61.1% and specificity 99.7%. At a cut-off value of 14 RU/ml indicated by the manufacturer for borderline results, sensitivity was 63.5% and specificity remained the same (99.7%). At a cut-off of 2.7 RU/ml, selected as the optimal cut-off on the basis of ROC curve analysis, sensitivity was 83.3% and specificity 95.1%. The best overall efficiency of the test was observed at 2.7 RU/ml; however, the highest positive likelihood ratio and diagnostic odds ratio were achieved at 14 RU/ml. A cut-off threshold higher than 14 RU/ml or lower than 2.7 RU/ml entailed worse test performance. Conclusion Depending on the clinical use (early diagnosis or as a support to confirm clinical diagnosis), nephrologists may take advantage of this evidence by choosing the most convenient cut-off. However, renal biopsy remains mandatory for the definitive diagnosis of iMN and for the assessment of disease severity.

The management of both acute and chronic cough requires a systematic and comprehensive approach. Despite the approved protocols for management, the pediatric assessment of cough and the corresponding prescribing attitude frequently do not fit these protocols, which can be affected by parental suggestions – sometimes substantially. Objective: The objective of this study was to investigate both the perception and the behavior of a representative sample of Italian pediatricians toward cough in real life. Methods: A specific questionnaire consisting of 18 questions was prepared. The questionnaire was completed by 300 pediatricians (all members of PAIDOSS: Italian National Observatory on Health of Childhood and Adolescence) who represented ~300,000 children. Results: A vast majority of children have cough throughout the year (99.3% of respondents have cough during autumn/winter and 64.7% in spring/summer). Allergic disease is the most frequent suspected cause of chronic cough in children (53%), and this is supported by the high demand for consultations: 73% seek the opinion of allergologists, 62% of otorhinolaryngologists and only 33% of pulmonologists. The majority of pediatricians (92%) reported that they prescribe therapy in acute cough regardless of cough guidelines. Moreover, the survey pointed out the abuse of aerosol therapy (26% in acute cough and 38% in chronic cough) and of antibiotics prescription (22% in acute cough and 42% in chronic cough). Conclusion: Our survey suggests that some Italian pediatricians’ therapeutic attitudes should be substantially improved in order to achieve better management of cough in children and to minimize the burden of cough.

Post-viral cough is a type of cough originating from upper respiratory tract infections that persists after the infection is resolved. Although it was hypothesized that bronchodilators might have a role in the management of post-viral cough, a clear demonstration of their efficacy is missing. Therefore, we tested the efficacy of a combination of a β-agonist and an anticholinergic agent in reducing post-viral cough with a randomized, double blind, placebo controlled clinical trial. Patients were treated for 10 days with either a nebulized combination of salbutamol 1.875 mg/0.5 mL and ipratropium bromide 0.375 mg/0.5 mL, or a placebo, and followed up for another 10 days. Daytime and nighttime cough severity and spirometry testing were assessed before starting treatment, after 10 and 20 days. Ninety-two patients were randomized to receive placebo (n = 46) or the active treatment (n = 46); nine of them (4 in the placebo group, 5 in the active treatment group) dropped out from the study. Daytime and nighttime cough severity were significantly reduced in both groups during the study period, but the reduction was more prominent in the active treatment group vs. placebo after 10 days of treatment (P = 0.003 for day cough; P = 0.061 for night cough), whereas at the end of follow-up period cough severity was comparable between the two groups. Small but significant increases in spirometric parameters were observed in the active treatment vs. placebo group, although at the end of follow-up these values returned to be comparable to placebo. The frequency of adverse events was not significantly different between the two groups of patients. We concluded that a combination of a β-agonist and an anticholinergic agent can effectively reduce post-viral cough, and can thus represent a valid option for this type of cough.

Cough is a frequent symptom associated to upper respiratory tract infections (URTIs) and, although being self-limiting, it might deeply affect the quality of life. Homeopathic products are often employed by patients to treat cough, but the evidence on their efficacy is scarce. Thus, we tested the efficacy of a homeopathic syrup in treating cough arising from URTIs with a randomized, double blind, placebo controlled clinical trial. Patients were treated with either the homeopathic syrup or a placebo for a week, and recorded cough severity in a diary by means of a verbal category-descriptive score for two weeks. Sputum viscosity was assessed with a viscosimeter before and after 4 days of treatment; patients were also asked to provide a subjective evaluation of viscosity. Eighty patients were randomized to receive placebo (n = 40) or the homeopathic syrup (n = 40). All patients completed the study. In each group cough scores decreased over time, however, after 4 and 7 days of treatment, cough severity was significantly lower in the homeopathic group than in the placebo one (p < 0.001 and p = 0.023, respectively). Sputum was collected from 53 patients: in both groups its viscosity significantly decreased after 4 days of treatment (p < 0.001); however, viscosity was significantly lower in the homeopathic group (p = 0.018). Instead, the subjective evaluation did not significantly differ between the two groups (p = 0.059). No adverse events related to any treatment were reported. We concluded that the homeopathic syrup employed in the study was able to effectively reduce cough severity and sputum viscosity, thereby representing a valid remedy for the management of acute cough induced by URTIs.

- Abstract
Objective: Certain psychiatric disorders, including depression, appear to impact adversely on bone health. Anxiety disorders are highly prevalent but few studies have examined their effects on bone tissue. This study investigated the effect of anxiety disorders on bone mineral density (BMD)., Methods: This prospective cohort study used data from the Geelong Osteoporosis Study. Participants were women and men aged ≥20 years randomly selected from the electoral roll and followed up for a mean of 14.7 and 11.0 years, respectively. Participants were assessed for a lifetime history of an anxiety disorder using the Structured Clinical Interview for DSM-IV-TR. BMD in the lumbar spine and femoral neck was measured using dual-energy x-ray absorptiometry., Results: Eight hundred and ninety women and 785 men participated in the study. Adjusting for sociodemographic, biometric and lifestyle factors, medical comorbidities and medication use, anxiety disorders were associated with reduced BMD at the lumbar spine (partial η
2 = 0.006; p = 0.018) and femoral neck (partial η2 = 0.006; p = 0.003) in men. These associations became non-significant when men with a history of comorbid mood disorders were excluded from the analysis. There was no significant association between anxiety disorders and BMD in women (p ≥ 0.168)., Conclusions: Anxiety disorders are associated with reduced BMD in men. This effect may be mediated by comorbid depression., (© 2023 The Authors. Acta Psychiatrica Scandinavica published by John Wiley & Sons Ltd.)- Published

- Abstract
Relapsing eosinophilic pneumonia and severe eosinophilic asthma are rare and disabling diseases, which share common inflammatory backgrounds and often require long-term systemic steroid therapy. Benralizumab is a humanized antibody targeting IL-5 receptor that reduces corticosteroid dependence and flares up in severe eosinophilic asthma on long term. In this case report, successful treatment of eosinophilic pneumonia and severe eosinophilic asthma with benralizumab is described after a 2-year follow up, showing the promising results of this therapy for eosinophilic pneumonia management., Competing Interests: The authors have no conflict of interest to declare., (© 2022 The Authors.)

- Abstract
Methane (CH
4 ) emission estimates from top-down studies over oil and gas basins have revealed systematic underestimation of CH4 emissions in current national inventories. Sparse but extremely large amounts of CH4 from oil and gas production activities have been detected across the globe, resulting in a significant increase of the overall oil and gas contribution. However, attribution to specific facilities remains a major challenge unless high-spatial-resolution images provide sufficient granularity within the oil and gas basin. In this paper, we monitor known oil and gas infrastructures across the globe using recurrent Sentinel-2 imagery to detect and quantify more than 1200 CH4 emissions. In combination with emission estimates from airborne and Sentinel-5P measurements, we demonstrate the robustness of the fit to a power law from 0.1 t C H 4 /h to 600 t C H 4 /h. We conclude here that the prevalence of ultraemitters (>25 t C H 4 /h) detected globally by Sentinel-5P directly relates to emission occurrences below its detection threshold in the range >2 t C H 4 /h, which correspond to large emitters covered by Sentinel-2 . We also verified that this relation is also valid at a more local scale for two specific countries, namely, Algeria and Turkmenistan, and the Permian basin in the United States.- Published

- Abstract
Background: Health-related quality of life (HRQoL) impairment is often reported among COVID-19 ICU survivors, and little is known about their long-term outcomes. We evaluated the HRQoL trajectories between 3 months and 1 year after ICU discharge, the factors influencing these trajectories and the presence of clusters of HRQoL profiles in a population of COVID-19 patients who underwent invasive mechanical ventilation (IMV). Moreover, pathophysiological correlations of residual dyspnea were tested., Methods: We followed up 178 survivors from 16 Italian ICUs up to one year after ICU discharge. HRQoL was investigated through the 15D instrument. Available pulmonary function tests (PFTs) and chest CT scans at 1 year were also collected. A linear mixed-effects model was adopted to identify factors associated with different HRQoL trajectories and a two-step cluster analysis was performed to identify HRQoL clusters., Results: We found that HRQoL increased during the study period, especially for the significant increase of the physical dimensions, while the mental dimensions and dyspnea remained substantially unchanged. Four main 15D profiles were identified: full recovery (47.2%), bad recovery (5.1%) and two partial recovery clusters with mostly physical (9.6%) or mental (38.2%) dimensions affected. Gender, duration of IMV and number of comorbidities significantly influenced HRQoL trajectories. Persistent dyspnea was reported in 58.4% of patients, and weakly, but significantly, correlated with both DLCO and length of IMV., Conclusions: HRQoL impairment is frequent 1 year after ICU discharge, and the lowest recovery is found in the mental dimensions. Persistent dyspnea is often reported and weakly correlated with PFTs alterations., Trial Registration: NCT04411459., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

- Abstract
Background: Autoantibodies against-phospholipase A2 receptor (PLA2R) are specific markers of idiopathic membranous nephropathy (iMN). Enzyme-linked immunosorbent assay (ELISA) is becoming the preferred method in many laboratories for the determination of anti-PLA2R antibodies, because it provides quantitative results, and is not prone to subjective interpretation, as is the case with indirect immunofluorescence assay., Methods: The purpose of our study was to determine the diagnostic performance of serum PLA2R antibodies detected by commercially available ELISA in a large Italian multicenter cohort of patients with biopsy-proven iMN and in patients with other renal diseases, with special focus on evaluating the optimal cut-off value to discriminate positive and negative results. A total of 495 consecutive patients were recruited. Renal biopsies were performed in all patients, and blood samples were taken before the initiation of immunosuppressive treatment., Results: According to the clinical diagnosis and to kidney biopsy, 126 patients were diagnosed with iMN and 369 had other non-membranous nephropathies. Anti-PLA2R autoantibodies were detected using a commercial anti-PLA2R ELISA. At a cut-off value of 20 relative units (RU)/ml indicated by the manufacturer for positive classification, sensitivity was 61.1% and specificity 99.7%. At a cut-off value of 14 RU/ml indicated by the manufacturer for borderline results, sensitivity was 63.5% and specificity remained the same (99.7%). At a cut-off of 2.7 RU/ml, selected as the optimal cut-off on the basis of ROC curve analysis, sensitivity was 83.3% and specificity 95.1%. The best overall efficiency of the test was observed at 2.7 RU/ml; however, the highest positive likelihood ratio and diagnostic odds ratio were achieved at 14 RU/ml. A cut-off threshold higher than 14 RU/ml or lower than 2.7 RU/ml entailed worse test performance., Conclusion: Depending on the clinical use (early diagnosis or as a support to confirm clinical diagnosis), nephrologists may take advantage of this evidence by choosing the most convenient cut-off. However, renal biopsy remains mandatory for the definitive diagnosis of iMN and for the assessment of disease severity.

- Abstract
Coronavirus disease 2019 (COVID-19) is often associated with interstitial pneumonia. However, there is insufficient knowledge on the presence of autoimmune serological markers in patients with COVID-19. We analyzed the presence and role of autoantibodies in patients with COVID-19-associated pneumonia. We prospectively studied 33 consecutive patients with COVID-19, 31 (94%) of whom had interstitial pneumonia, and 25 age-matched and sex-matched patients with fever and/or pneumonia with etiologies other than COVID-19 as the pathological control group. All patients were tested for the presence of antinuclear antibodies (ANAs), anti-antiphospholipid antibodies, and anti-cytoplasmic neutrophil antibodies (ANCAs). Clinical, biochemical, and radiological parameters were also collected. Fifteen of 33 patients (45%) tested positive for at least one autoantibody, including 11 who tested positive for ANAs (33%), 8 who tested positive for anti-cardiolipin antibodies (immunoglobulin (Ig)G and/or IgM; 24%), and 3 who tested positive for anti-β2-glycoprotein antibodies (IgG and/or IgM; 9%). ANCA reactivity was not detected in any patient. Patients that tested positive for auto-antibodies had a significantly more severe prognosis than other patients did: 6 of 15 patients (40%) with auto-antibodies died due to COVID-19 complications during hospitalization, whereas only 1 of 18 patients (5.5%) who did not have auto-antibodies died (P = 0.03). Patients with poor prognosis (death due to COVID-19 complications) had a significantly higher respiratory rate at admission (23 breaths per minute vs. 17 breaths per minute; P = 0.03) and a higher frequency of auto-antibodies (86% vs. 27%; P = 0.008). In conclusion, auto-antibodies are frequently detected in patients with COVID-19 possibly reflecting a pathogenetic role of immune dysregulation. However, given the small number of patients, the association of auto-antibodies with an unfavorable prognosis requires further multicenter studies., (© 2020 The Authors.

- Abstract
Background and Objectives: Peach gibberellin-regulated protein (peamaclein) has recently emerged as a relevant food allergen in cypress pollen-hypersensitive patients. Objective: We investigated monosensitization to peamaclein among Italian cypress pollen-allergic patients., Material and Methods: A total of 835 cypress pollen-hypersensitive patients from 28 Italian allergy centers underwent a thorough work-up to determine food-allergic reactions and performed skin prick testing with a commercial peach extract containing peamaclein. IgE to rPru p 3 was measured in peach reactors, and those with negative results were enrolled as potentially monosensitized to peamaclein. IgE reactivity to rPru p 7 was evaluated using immunoblot and an experimental ImmunoCAP with rPru p 7., Results: Skin prick tests were positive to peach in 163 patients (19.5%); however, 127 (77.9%) were excluded because they reacted to Pru p 3. Twenty-four patients (14.7%) corresponding to 2.8% of the entire study population) were considered potentially monosensitized to peamaclein. No geographic preference was observed. Seventeen of the 24 patients (70.8%) had a history of food allergy, mainly to peach (n=15). Additional offending foods included other Rosaceae, citrus fruits, fig, melon, tree nuts, and kiwi. On peach immunoblot, only 3 of 18 putative peamaclein-allergic patients reacted to a band at about 7 kDa; an additional 4 patients reacted at about 50-60 kDa. Ten of 18 patients (56%) had a positive result for Pru p 7 on ImmunoCAP., Conclusion: Allergy and sensitization to peamaclein seem rare in Italy. Most patients react to peach, although other Rosaceae fruits and several citrus fruits may also be offending foods. Peach and cypress pollen probably also share cross-reacting allergens other than peamaclein.
