Abstract
Experimental mouse studies are important to gain a comprehensive, quantitative and mechanistic understanding of the biological factors that modify individual risk of radiation-induced health effects, including age at exposure, dose, dose rate, organ/tissue specificity and genetic factors. In this study, neonatal Ptch1+/- mice bred on CD1 and C57Bl/6 background received whole-body irradiation at postnatal day 2. This time point represents a critical phase in the development of the eye lens, cerebellum and dentate gyrus (DG), when they are also particularly susceptible to radiation effects. Irradiation was performed with γ rays (60Co) at doses of 0.5, 1 and 2 Gy, delivered at 0.3 Gy/min or 0.063 Gy/min. Wild-type and mutant mice were monitored for survival, lens opacity, medulloblastoma (MB) and neurogenesis defects. We identified an inverse genetic background-driven relationship between the radiosensitivity to induction of lens opacity and MB and that to neurogenesis deficit in Ptch1+/- mutants. In fact, high incidence of radiation-induced cataract and MB were observed in Ptch1+/-/CD1 mutants that instead showed no consequence of radiation exposure on neurogenesis. On the contrary, no induction of radiogenic cataract and MB was reported in Ptch1+/-/C57Bl/6 mice that were instead susceptible to induction of neurogenesis defects. Compared to Ptch1+/-/CD1, the cerebellum of Ptch1+/-/C57Bl/6 mice showed increased radiosensitivity to apoptosis, suggesting that differences in processing radiation-induced DNA damage may underlie the opposite strain-related radiosensitivity to cancer and non-cancer pathologies. Altogether, our results showed lack of dose-rate-related effects and marked influence of genetic background on the radiosensitivity of Ptch1+/-mice, supporting a major contribution of individual sensitivity to radiation risk in the population.

Abstract
One harmful long-term effect of ionizing radiation is cataract development. Recent studies have been focused on elucidating the mechanistic pathways involved in this pathogenesis. Since accumulating evidence has established a role of microRNAs in ocular diseases, including cataract, the goal of this work was to determine the microRNA signature of the mouse lens, at short time periods postirradiation, to understand the mechanisms related to radio-induced cataractogenesis. To evaluate the differences in the microRNA profiles, 10-week-old Patched1 heterozygous (Ptch1+/-) mice, bred onto two different genetic backgrounds (CD1 and C57Bl/6J), received whole-body 2 Gy γ-ray irradiation, and 24 h later lenses were collected. Next-generation sequencing and bioinformatics analysis revealed that genetic background markedly influenced the list of the deregulated microRNAs and the mainly predicted perturbed biological functions of 2 Gy irradiated Ptch1+/- mouse lenses. We identified a subset of microRNAs with a contra-regulated expression between strains, with a key role in regulating Toll-like receptor (TLR)-signaling pathways. Furthermore, a detailed analysis of miRNome data showed a completely different DNA damage response in mouse lenses 24 h postirradiation, mainly mediated by a marked upregulation of p53 signaling in Ptch1+/-/C57Bl/6J lenses that was not detected on a CD1 background. We propose a strict interplay between p53 and TLR signaling in Ptch1+/-/C57Bl/6J lenses shortly after irradiation that could explain both the resistance of this strain to developing lens opacities and the susceptibility of CD1 background to radiation-induced cataractogenesis through activation of epithelial-mesenchymal transition.

Abstract
BACKGROUND COVID-19 has challenged the health system organization requiring a fast reorganization of diagnostic/therapeutic pathways for patients affected by time-dependent diseases such as acute coronary syndromes (ACS). AIM To describe ACS hospitalizations, management, and complication rate before and after the COVID-19 pandemic was declared. DESIGN Ecological retrospective study. Methods: We analyzed aggregated epidemiological data of all patients > 18 years old admitted for ACS in twenty-nine hub cardiac centers from 17 Countries across 4 continents, from December 1st, 2019 to April 15th, 2020. Data from December 2018 to April 2019 were used as historical period. RESULTS A significant overall trend for reduction in the weekly number of ACS hospitalizations was observed (20.2%; 95% confidence interval CI [1.6, 35.4] P = 0.04). The incidence rate reached a 54% reduction during the second week of April (incidence rate ratio: 0.46, 95% CI [0.36, 0.58]) and was also significant when compared to the same months in 2019 (March and April, respectively IRR: 0.56, 95%CI [0.48, 0.67]; IRR: 0.43, 95%CI [0.32, 0.58] p < 0.001). A significant increase in door-to-balloon, door-to-needle, and total ischemic time (p <0.04 for all) in STEMI patents were reported during pandemic period. Finally, the proportion of patients with mechanical complications was higher (1.98% vs. 0.98%; P = 0.006) whereas GRACE risk score was not different. CONCLUSIONS Our results confirm that COVID-19 pandemic was associated with a significant decrease in ACS hospitalizations rate, an increase in total ischemic time and a higher rate of mechanical complications on a international scale.

Abstract
Abstract
Background
The Academic Research Consortium High Bleeding Risk (ARC-HBR) criteria have been proposed to stratify the bleeding risk of patients undergoing percutaneous coronary intervention (PCI). While most criteria were established, 4 criteria have been proposed on a de novo basis.
Purpose
We assessed the prevalence and prognosis of new ARC-HBR criteria in a contemporary, prospective, multicenter, quality-improvement registry of all-comers patients with acute coronary syndromes.
Methods
Between 2016 and 2020, consecutive subjects were enrolled; baseline characteristics and medications were prospectively collected, and patients were followed-up at 1 year. All clinical events (including bleeding) were adjudicated by an independent committee. All 17 ARC-HBR criteria were individually evaluated by reviewing patients' charts.
Results
Of the 2804 patients enrolled, 782 (28.0%) met the ARC-HBR definition and 47 (6%) of them experienced a major BARC 3 or 5) bleeding at 1-year. HBR patients had a significantly higher risk of BARC 3–5 bleedings (HR for: 3.07; 95% CI: 2.02–4.67; p<0.0001; Fig. 1A), BARC 2–5 (HR: 1.845; 95% CI: 1.4–2.42; p<0.0001). Fig. 1B indicates the proportion of patients meeting each criterion. Age, (moderate or severe) chronic kidney disease, (moderate or severe) anemia and oral anticoagulant therapy included 88% of HBR patients.
The 4 new ARC-HBR criteria, all together, were present in only 1.7% of our population: 1.0% was planned for major surgery while on dual antiplatelet therapy, 0.5% had a recent intracranial hemorrhage/ictus or brain arteriovenous malformations, 0.1% had hepatic cirrhosis with portal hypertension and 0.1% had a recent surgery or trauma. In a multivariable Cox regression analysis including individual ARC-HBR criteria, only CKD (major and minor criteria), anemia (major and minor criteria) and cancer were the independent predictors of BARC 3–5 events with a concordance-index for this model of 0.698 (p<0.001). In a second model including only CKD (major criterion), anemia (major criterion), age and oral anticoagulation therapy, all these criteria were independent predictors of BARC 3–5 events with a concordance index of 0.674 (pmodel<0.001 for the model) (Fig. 2).
Conclusion
Almost one third of contemporary ACS patients was at HBR according to the ARC-HBR definition and these patients presented a significantly higher risk of bleedings at 1-year. The most common 4 criteria (age, CKD, anemia, and oral anticoagulant therapy) allowed the identification of 88% of HBR patients. The newly proposed HBR criteria were extremely rare and therefore challenging to validate and of uncertain clinical utility. These data may inform and simplify clinical decision making and provide priority for future directions of HBR definitions.

Abstract
Abstract
Background
Lipid management plays a key role in secondary prevention after acute coronary syndrome. The 2019 European Society of Cardiology guidelines recommend a more ambitious target than the previous guidelines version (i.e., to achieve LDL cholesterol [LDL-C] <55 mg/dL, and to reduce it ≥50% form baseline vs LDL-C<70 mg/dl or reduced ≥50% form baseline). Currently, data on the reduction of cardiovascular events in patients achieving the 2019 goals in a real-world population are missing.
Purpose
The aim of this study was to determine the risk of major adverse cardiovascular events (MACE) during follow-up in post myocardial infarction (PMI) patients according to the achievement of the guidelines-recommended goals in terms of LDL-C reduction.
Methods
We conducted a retrospective analysis of a monocentric observational registry prospectively enrolling patients admitted to our hospital for ST segment elevation myocardial infarction and followed-up in our dedicated PMI ambulatory. The analysis considered the patients enrolled between January 2011 and February 2019. Demographical and clinical data were extracted from a dedicated digital database, and the clinical events occurred during follow-up were obtained by telephone interviews or clinical records. We considered a combined endpoint of MACE defined as all-cause death, non-fatal MI, non-fatal stroke and unplanned revascularization. LDL-C was collected at baseline and at 1, 6 and 12 months after the event. The lower value collected at follow-up was used to define the achievement of the target goals. We conducted a Kaplan-Meier analysis and log-rank test comparing patients who achieved LDL-C <55 mg/dL and ≤50% from baseline (group 2019) vs those with LDL-C <70 mg/dL or ≤50% from baseline (group 2016). Continue variable are presented as median (interquartile range).
Results
A total of 1201 patients (23% female) were included in our analysis. Median age was 63 (54–72) years, 56% had hypertension, 17% diabetes, and 38% were smoker. Baseline LDL-C was 123 (97–148) mg/dL, the median LDL-C at follow-up was 63 (52–78) mg/dL, significantly reduced from baseline (P<0.0001). Between 6 and 12 months 83% of patients were treated with statin therapy alone (73% high intensity), and 17% with the addition of ezetimibe. The 2016 target was achieved in 828 patients (69%), while 270 patients (22.5%) obtained also the 2019 target. Median follow-up was 60 (40–77) months. The net incidence of MACE was 12.9% in group 2019 vs 23.7% in group 2016 (HR 0.61; 95% CI 0.42–0.88; P log-rank=0.0087; Number Needed to Treat=9; see Figure).
Conclusion
Our data from a real-world cohort of PMI patients emphasize the importance of achieving the guideline-recommended secondary prevention goals of LDL-C<55 mg/dl and ≤50% from baseline in order to reduce MACE.

Abstract
Abstract
Background
Many ST-segment elevation acute coronary syndrome (STEACS) patients fail to activate the Emergency Medical System (EMS), with possible dramatic consequences. Prior studies focusing on barriers to EMS activation include patients with any acute coronary syndrome (ACS) without representation of southern European populations. However, barriers are influenced by the ACS type and by socio-demographic and racial factors.
Purpose
We aimed to investigate the barriers to EMS call for patients diagnosed for STEACS in Italy.
Methods
A prospective, single-center, survey-based study, including all the patients treated with primary percutaneous coronary intervention for STEACS in a tertiary hospital in northern Italy from 1st June 2018 to 31st May 2020.
Results
The questionnaire was filled out by 293 patients. The majority of the participants were males (74%), married (70.4%), with a high-school degree (38.4%) and with a median age of 62 years. Chest pain as a possible symptom related to a cardiovascular attack is known by most of the respondents (89%), and left arm pain/shake by 53.7% of them, whilst the other possible signs and symptoms (i.e. dyspnea, asthenia, sweating, nausea, vomiting, dizziness) were unknown to the majority of the participants. Only 191 (65.2%) of the participants activated the EMS after symptoms onset. The main reasons for not calling EMS were the perception that symptoms were not related to an important health problem (45.5%) and that a private vehicle is faster than EMS to reach the hospital (34.7%). The median time to first medical contact was 60 minutes, and it was significantly higher in the patients who did not called EMS compared to those who did (180 [60–420] mins vs 35 [15–120] mins, p<0.001). The patients who called a private doctor after symptoms onset did not called EMS more frequently than those who did not (5.9% vs 8.2%, p=0.3). Moreover, 30% of the patients who did not call the EMS would still act in the same way if a new episode occurred and the main reasons for this were that they think to be faster than EMS (57.1%) and to live close to the hospital (17.9%). Analyzing predictors of EMS activation, only prior history of cardiovascular disease has been demonstrated to be a predictor of calling the EMS in case of symptoms suspected for STEACS.
Conclusions
Our study, from the southern Europe, showed that a substantial percentage of patients with symptoms suspected for STEACS preferred private vehicle rather than activating the EMS. Our results highlight the need for information campaigns targeted to both the general population and medical doctors, stressing that the EMS is faster than a private vehicle to direct the patient to the right hospital and increasing the awareness of the people on the type of possible heart attack symptoms, which seem to be the most neglected issues by patients who did not call the EMS.

Abstract
Abstract
Background
Sodium-glucose transporter 2 inhibitors (SGLT2-i) have demonstrated substantial improvement in clinical outcomes for patients with heart failure (HF) and chronic kidney disease (CKD) with or without diabetes mellitus (DM). Prescription patterns and outcome of SGLT2-i candidates in patients hospitalized for an acute coronary syndrome (ACS) are less well established.
Purpose
We aimed to assess the proportion of candidates to SGLT2-i and to characterize their clinical outcome in a contemporary, prospective, multicenter, quality-improvement study of all-comers patients with ACS. We also aimed to ascertain prescriptions of SGLT2-i at discharge.
Methods
Between 2018 and 2020, subjects were enrolled in the study; baseline characteristics and medications were prospectively collected, and patients were followed-up at 1 year. Subjects were considered candidates to SGLT2-i if any of the following were: (i) known (medically treated) or new (HbA1c >6.5%) diagnosis of type 2 DM; (ii) left ventricular systolic dysfunction (LVSD; new or known left ventricular ejection fraction <40%) or clinical HF; (iii) CKD (estimated glomerular filtration rate 25–74 mL/min/m2, according to DAPA-CKD trial eligibility).
Results
Of the 2804 consecutive ACS patients enrolled, 798 (28.5%) had new or known DM and only 10 were already on SGLT2-I at baseline. Additionally, 1,098 (39.2%) patients qualified for SGLT2-i prescription as having known or new LVSD or HF, and 803 (28.6%) as having CKD. (Fig. 1A) Overall, these 1,767 (63.1%) SGLT2-i candidates had substantially higher hazard of death as compared to no candidate (Hazard Ratio [HR] at 1-year: 6.82; 95% Confidence Interval: 4.32–10.8; p<0.001; Fig. 1B) and each indication to SGLT2-i independently predicted death at 1 year (HR: 2.30/2.11/3.06; 95% CI: 1.78–2.97/1.62–2.74/2.35–3.97; all p<0.0001; for DM, HF, CKD, respectively; Fig. 2). At discharge, only 18 (1.0% of the candidates) were prescribed with SGLT2-i and, of those with DM, having a diabetological consultation before discharged modestly but significantly increased the likelihood of being discharged with SGLT2-i (4.3% vs. 6.6%; p=0.0015).
Conclusion
Most (two out of three) contemporary ACS patients are candidates to SGLT2-i therapy, and they have a significant and substantial higher risk of mortality at 1-year as compared to no candidates. Current prescription rates are still extremely low (1%) and highlight opportunity for quality improvement and multidisciplinary decision-making.

Abstract
Respiratory infections (RI) significantly burden patients, their families, and society. Respiratory infection recurrence (RRI) usually depends on a defect of the immune response, which can be more or less transient and/or selective. In particular, children, older people, heavy smokers, and patients with chronic diseases, characterized by an inadequate immune response, may be at risk of developing RRI. In this context, OM- 85 could represent a valuable option in the management of RRI. OM-85 is a bacterial lysate containing the extracts of some common pathogens, including Branhamella catarrhalis, Klebsiella pneumoniae, Klebsiella ozaenae, Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus viridans, and Staphylococcus aureus. Methodologically rigorous studies have documented the mechanism of action, efficacy, and safety of OM-85. OM-85 enhances the natural and acquired immune response through multifaceted mechanisms. Substantial evidence has shown that OM-85 can prevent respiratory infections, reduce the number of COPD exacerbations, and shorten the disease duration at home or in hospital. OM-85 can enhance the effectiveness of the 'flu vaccination without affecting the vaccine tolerability. The preventive use of OM-85 can reduce the use of antibiotics, contributing to contrast antibiotic resistance and saving the high cost of chronic respiratory diseases. Further studies should define the ideal candidate to OM-85 treatment.

Abstract
Recent epidemiological findings and reanalysis of historical data suggest lens opacities resulting from ionizing radiation exposures are likely induced at lower doses than previously thought. These observations have led to ICRP recommendations for a reduction in the occupational dose limits for the eye lens, as well as subsequent implementation in EU member states. The EU CONCERT LDLensRad project was initiated to further understand the effects of ionizing radiation on the lens and identify the mechanism(s) involved in radiation-induced cataract, as well as the impact of dose and dose-rate. Here, we present the results of a long-term study of changes to lens opacity in male and female adult mice from a variety of different genetic (radiosensitive or radioresistant) backgrounds, including mutant strains Ercc2 and Ptch1, which were assumed to be susceptible to radiation-induced lens opacities. Mice received 0.5, 1 and 2 Gy 60Co gamma-ray irradiation at dose rates of 0.063 and 0.3 Gy min-1. Scheimpflug imaging was used to quantify lens opacification as an early indicator of cataract, with monthly observations taken postirradiation for an 18-month period in all strains apart from 129S2, which were observed for 12 months. Opacification of the lens was found to increase with time postirradiation (with age) for most mouse models, with ionizing radiation exposure increasing opacities further. Sex, dose, dose rate and genetic background were all found to be significant contributors to opacification; however, significant interactions were identified, which meant that the impact of these factors was strain dependent. Mean lens density increased with higher dose and dose rate in the presence of Ercc2 and Ptch1 mutations. This project was the first to focus on low (<1 Gy) dose, multiple dose rate, sex and strain effects in lens opacification, and clearly demonstrates the importance of these experimental factors in radiobiological investigations on the lens. The results provide insight into the effects of ionizing radiation on the lens as well as the need for further work in this area to underpin appropriate radiation protection legislation and guidance.

Abstract
Histamine is a chemical mediator, released predominantly by tissue mast cells, circulating basophils, and neurons, which are activated in response to various immunological and non-immunological stimuli. Histamine has to bind to specific receptors to exert its physiological and pathophysiological functions. Endogenous histamine is the main mediator of the immediate allergic response, which moreover, performs other multiple functions, including regulation of gastric secretion, neurotransmission in the central nervous system, and immunomodulatory activity. The involvement of histamine in various disorders and the importance of receptors in the clinical features have relevant implications in clinical practice. Anti-H1 antihistamines contrast the histamine-dependent effects, mainly concerning nasal symptoms and cutaneous itching and wheal. Antihistamines are among the most prescribed drugs in pediatric care. This review updates the practical use of antihistamines in children and adolescents.

Abstract
Abstract
Introduction
Left atrial appendage thrombosis (LAAT) is a dangerous condition that mainly affects patients with atrial fibrillation (AF) or those with mitral stenosis (MS), increasing their risk of stroke. Transesophageal echocardiography (TEE) is the gold standard for the diagnosis of LAAT but some technical issues and the suboptimal sensitivity in identifying small thrombi, especially within a side lobe, can limit its clinical usefulness. Reliable non-invasive diagnostic methods could be useful in clinical practice. D-dimer, a fibrin degradation product already commonly used in the diagnostic work-up of conditions such as venous thromboembolism, may have a role as a non-invasive marker of LAAT.
Purpose
To evaluate the diagnostic performance of D-dimer for the detection of LAAT in patients with AF and/or MS, using TEE as the reference standard.
Methods
We searched the literature for studies that evaluated the ability of D-dimer to predict LAAT. For each study a 2x2 table of D-dimer positivity and LAAT presence was constructed. Sensitivity, specificity, positive predictive value and negative predictive value were calculated. Considering the different diagnostic thresholds used in the included studies, the overall sensitivity and specificity were calculated using a hierarchal summary receiver operating characteristic (HSROC) model and a SROC curve was generated.
Results
6 studies, evaluating 1380 patients of whom 154 had LAAT, were included in the analysis. The prevalence of LAAT in the studies ranged from 9% to 26%, with a median of 12%. The mean age was 60±13 years, 63% were male. The mean left atrial diameter was 43±3 mm. The D-dimer diagnostic threshold ranged from 200 mcg/l to 1150 mcg/l. The overall sensitivity calculated with the HSROC model was 85%±28% and the overall specificity was 82%±29%. The negative predictive value was 98%. Figure 1 shows the summary ROC curve: individual studies are depicted by a clear circle; the red circle marks the pooled sensitivity and specificity across the 6 studies. The red dot-dashed-curve marks the boundary of the 95% credible region for the pooled estimates of sensitivity and specificity.
Conclusions
Our analysis shows that D-dimer has a good diagnostic performance with a very high negative predictive value for LAAT and therefore it might be of clinical aid for ruling out the presence of LAAT in patients with AF and/or MS. Further studies are needed to determine the best diagnostic threshold.

Abstract
INTRODUCTION Although the long term negative effects of bronchopulmonary dysplasia (BPD) are well known, follow-up studies of preterm infants with BPD into childhood are lacking. METHODS Forty-two preschool children (age range 3-6 years) who were born before 32 weeks of gestational age and affected by BPD were enrolled. Pre-, peri-, and post-natal data were collected. During the follow up appointment complete physical examination and lung function (impulse oscillometry (IOS)) were recorded. The European Community Respiratory Health Survey (ECRHS) questionnaire was administered to all enrolled subjects. RESULTS Thirty patients were included in the final analysis. The BPD group did not differ in comparison to the non-BPD group in terms of lung function (p > 0.05). By comparing all subjects enrolled, We detected extremely low-birth-weight (ELBW) infants with height-, weight-, and gender-related reference values and a significant trend of increasing resistance values (R5Hz, R5-20 Hz) and respiratory impedance (Z5Hz) (p < 0.05). No significant difference in bronchial reversibility test was observed among BPD non-BPD groups (p < 0.05). The frequency of gastroesophageal reflux disease was significantly higher in patients with BPD when compared to non-BPD group (p < 0.05). Significant differences in gestational age, oxygen supplementation (days), mechanical ventilation therapy (days), and sepsis between BPD and non-BPD groups were also observed (p < 0.05). There were no significant differences in the prevalence of family and personal history of atopy and/or allergic diseases, tobacco exposure, respiratory symptoms, respiratory syncytial virus bronchiolitis, exercise induced dyspnea, treatment with ß-2 bronchodilators and inhaled corticosteroids among the groups (p > 0.05). CONCLUSIONS The respiratory function in preschool children born with ELBW is characterized by an increase in impedance and resistance of small airways. No statistically significant differences were found between ELBW children with BPD and without BPD. With regards to the smallest gestational age, the longer duration of O2 therapy during hospitalization, and sepsis significantly resulted in a worse respiratory function.

Abstract
Abstract
Background
Patients with cancer are at higher risk of atrial fibrillation (AF) compared with the general population. Furthermore, cancer per se and anti-cancer treatments have been associated with thromboembolic complications and increased bleeding risk. Considering that only 12% of cancer patients can achieve a stable International Normalized Ratio target and the frequent need for invasive procedures, warfarin is not an ideal option. Direct oral anticoagulants may theoretically represent a valid alternative although their use in this population has been scarcely investigated.
Purpose
To compare efficacy and safety of direct oral Xa inhibitors (DOXaI) versus warfarin in patients with atrial fibrillation and cancer.
Methods
We searched electronic databases for randomized controlled trials (RCTs) that analyzed the use of DOXaI versus warfarin in patients with AF and cancer. The primary efficacy outcome was stroke or systemic embolism (SE). The secondary efficacy outcomes were ischemic stroke, myocardial infarction and all-cause death. The primary safety outcome was major bleeding; secondary safety outcomes were major or clinically relevant non-major bleeding, intracranial bleeding and any bleeding. The net clinical benefit was estimated as the composite of the two primary outcomes. A sensitivity analysis was performed to better define the incidence of these outcomes in patients with active cancer. The statistical software ProMeta 3 was used to estimate the risk ratio with a random-effect model.
Results
3 RCTs counting a total of 3029 cancer patients (1682 on DOXaI and 1347 on warfarin), 1354 of whom with active cancer (856 on DOXaI and 502 on warfarin), were included in the analysis. Mean age was 75.6 ± 1.2 years, and 32% were female. Mean follow-up period was 2.2 ± 0.6 years. The most common cancer sites were prostate (23%), gastrointestinal tract (22.2%), breast (12.1%) and genitourinary tract (10.6%). The mean CHADS2 score was 2.9 ± 0.6 and the mean HAS-BLED score was 2.6 ± 0.4.
There were no significant differences in the risk of stroke or SE (RR 0.76; 95% CI 0.52-1.10) as well as for all the other secondary efficacy outcomes. DOXaI significantly reduced the incidence of major bleeding in the overall cancer population (RR 0.79; 95% CI 0.63-0.99; p = 0.039); this finding was consistent also in patients with active cancer (RR 0.79; 95% CI 0.59-1.05) although the effect was not statistically significant. DOXaI also significantly reduced intracranial bleeding in overall cancer population (RR 0.12; 95% CI 0.02-0.63; p = 0.013) and any bleeding in active cancer patients (RR 0.87; 95% CI 0.77-0.98; p = 0.026). Furthermore, DOXaI significantly reduced the composite endpoints of major bleeding and stroke or SE in overall cancer population (RR 0.78; 95% CI 0.64-0.94; p = 0.008).
Conclusions
Our metanalysis shows that, in patients with atrial fibrillation and cancer, DOXaI are safer and have a similar efficacy compared with warfarin.

Abstract
BACKGROUND AND AIMS At the rear edge of the distribution of species, extreme isolation and small population size influence the genetic diversity and differentiation of plant populations. This may be particularly true for Arctic-alpine species in mid-latitude mountains, but exactly how peripherality has shaped their genetic and reproductive characteristics is poorly investigated. The present study, focused on Salix herbacea, aims at providing new insights into the causes behind ongoing demographic dynamics and their consequences for peripheral populations of Arctic-alpine species. METHODS We performed a whole-population, highly detailed sampling of the only two S. herbacea populations in the northern Apennines, comparing their clonal and genetic diversity, sex ratio and spatial genetic structure with a reference population from the Alps. After inspecting ~1800 grid intersections in the three populations, 563 ramets were genotyped at 11 nuclear microsatellite markers (nSSRs). Past demography and mating patterns of Apennine populations were investigated to elucidate the possible causes of altered reproductive dynamics. KEY RESULTS Apennine populations, which experienced a Holocene bottleneck and are highly differentiated (FST = 0.15), had lower clonal and genetic diversity compared with the alpine population (RMLG = 1 and HE = 0.71), with the smaller population exhibiting the lowest diversity (RMLG = 0.03 and HE = 0.24). An unbalanced sex ratio was found in the larger (63 F:37 M) and the smaller (99 F:1 M) Apennine population. Both were characterized by the presence of extremely large clones (up to 2500 m2), which, however, did not play a dominant role in local reproductive dynamics. CONCLUSIONS Under conditions of extreme isolation and progressive size reduction, S. herbacea has experienced an alteration of genetic characteristics produced by the prevalence of clonal growth over sexual reproduction. However, our results showed that the larger Apennine population has maintained levels of sexual reproduction enough to counteract a dramatic loss of genetic and clonal diversity.

Abstract
Abstract
Background and aim
Hypertrophic cardiomyopathy (HCM) is a genetic based cardiomyopathy with heterogeneous phenotypic expression. Since it is one of the most common cause of sudden cardiac death (SCD) in the young different risk score have been proposed to properly identify the patients that would benefit from a primary prevention with an implantable cardioverter-defibrillator (ICD). ESC guidelines on HCM suggest to estimate the risk of SCD considering clinical and echocardiographic parameters and mention the use of cardiac magnetic resonance (CMR) only in the case of poor echo windows. The aim of the present study-level meta-analysis was to explore the prognostic value of late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) for adverse fatal events.
Methods
We searched PubMed and EMBASE for studies that investigated the prognostic value of LGE in patients with HCM. The outcomes of interest were SCD or aborted SCD, all-cause mortality and cardiovascular (CV) mortality. Random-effects Odds Ratios (ORs) were estimated using a DerSimonian-Laird method with a person-year approach. Moreover, an univariate meta-regression was performed to assess the moderator effect of mean age, LGE % of left ventricle (LV) and gender (expressed as male percentage).
Results
A total of 7 studies (n=3351) were included in the analysis. Mean follow-up was 3±0.63 years. Mean age was 47.7±14.6 years and 56.9% were male. LGE was detected in 1845 (55%) patients with a mean LGE percentage of LV of 7%. The presence of LGE was associated with an increased incidence of SCD or aborted SCD (OR 3.44; 95% CI 2.02–5.86; p<0.001- Figure), all-cause mortality (OR 1.92; 95% CI 1.31–2.81; p<0.001) and CV mortality (OR 3.16; 95% CI 1.77–5.64; p<0.001) compared with the absence of LGE at CMR. The LGE percentage of LV, mean age and gender did not have any moderator effect on the outcomes of interest. However, LGE % of LV was reported only in 4 studies and the absence of any moderator effect of this parameter could be due to a type II error.
Prognostic value of LGE for SCD
Conclusions
The presence of LGE at CMR in patients with HCM exhibited a substantial prognostic value in fatal events and, in particular, in the prediction of SCD. LGE assessment is an effective tool to stratify the arrhythmic risk in HCM. Therefore, it should be considered, especially in borderline cases, to improve the identification of HCM patients who could benefit from ICD implantation.

Abstract
The advent of new 'omics' techniques determined a massive boost in the measurement of the whole spectra of molecules within cells, favoring promising new radiobiological studies at low doses. The main aim of this work was to assess the radiation-induced perturbations of miRNA profiles and their temporal dynamics. Human Umbilical Vein Endothelial Cells were irradiated with low doses of γ-rays. At different time points post-irradiation, cells were harvested and miRNAs isolated. A full mapping of the miRNA sequences via Next-Generation-Sequencing analysis was performed followed by bioinformatic analyses. Pathway enrichment analyses on the differentially expressed miRNAs focused both on the averaged effects of different doses over the 24-h experiment and on the altered temporal dynamics of the miRNA profiles. These complementary analyses provided a picture of the dose- and time-dependent miRNAs responses, allowing to better explore the candidate biomarkers linked to radiation exposures and their corresponding pathways and functions.

Abstract
AIM This study determined cardiovascular impairment in young children with obstructive respiratory disease who were assessed using the opening interrupter technique (RINT). METHODS This pilot study enrolled 41 children who had been referred to pulmonology and allergology specialists at the University of Catania, Italy, from March to July 2017: 23 (mean age 4.13 ± 0.62 years) had chronic coughs and wheezing and 18 controls (mean age 4.27 ± 0.66 years) had obstructive chest disease, but were otherwise healthy. Airway resistance was evaluated using RINT and cardiac function by studying the ejection fraction, pulmonary artery systolic pressure (PASP), tricuspid annular plane systolic excursion and tricuspid flow propagation velocity (TFPV). RESULTS The RINT and PASP values were significantly higher in the patient group when compared to the controls, but the TFPV values were lower. A direct and significant Spearman's correlation coefficient (r) between RINT and PASP values was observed (r = 0.81). We found a significant inverse correlation between RINT and TFPV (r = -0.83), as well as TFPV and PASP (r = -0.78). CONCLUSION This study showed that children with obstructive respiratory diseases had a major risk of cardiovascular impairment. Impaired diastolic function of the right ventricle occurred very early when airway resistance was abnormally increased.

Abstract
BACKGROUND Although several studies suggest a possible link between dyslipidemia and atopy, literature findings are still unclear. OBJECTIVE The aim of the study was to investigate the relationship between dyslipidemia and atopy in a pediatric population affected by dyslipidemia or dyslipidemia/atopic predisposition. MATERIALS AND METHODS Children with dyslipidemia, dyslipidemia and atopy as well as healthy children were recruited. Serum total IgE, IL-10, IL-17, and IL-23 levels as well as fasting lipid values (total cholesterol, LDL, HDL and triglycerides) were performed on all enrolled children. RESULTS The present study evaluated 23 patients affected by dyslipidemia, 26 patients affected by atopy and dyslipidemia and, 22healthy children. Serum total IgE levels significantly related also with serum cholesterol levels: positively with total cholesterol (p<0.05), LDL (p<0.05), and tryglicerides (p<0.001), but negatively with HDL (p<0.05). Serum levels of IL-10 were lower in children with atopy and dyslipidemia than patients with dyslipidemia (p<0.001). Serum IL-10 levels significantly related also with serum cholesterol levels: negatively with total cholesterol (p<0.001), LDL (p<0.05), and triglycerides (p<0.05), but positively with HDL (p<0.05). Serum IL-17 and IL-23 levels showed the same trend. They were significantly higher in children with atopy and dyslipidemia than patients with dyslipidemia (p<0.001). In particular, serum IL-17 and IL-23 values positively correlated with serum total IgE levels (p<0.05); serum total cholesterol levels (p<0.001); serum LDL levels (p<0.001); serum triglycerides levels (p<0.05). Although not statistically significant, an inverse correlation has been noted between serum IL-17, IL-23 and HDL levels. CONCLUSIONS These findings support the notion that dyslipidemia and atopic predisposition share the same immune pathways as well as they offer new insights in the complex crosstalk between hyperlipidemia and atopy.

Abstract
The dynamics of the velocity field resulting from the interaction between the atmospheric boundary layer and a wind turbine array can affect significantly the performance of a wind power plant and the durability of wind turbines. In this work, dynamics in wind turbine wakes and instabilities of helicoidal tip vortices are detected and characterized through modal decomposition techniques. The dataset under examination consists of snapshots of the velocity field obtained from large-eddy simulations (LES) of an isolated wind turbine, for which aerodynamic forcing exerted by the turbine blades on the atmospheric boundary layer is mimicked through the actuator line model. Particular attention is paid to the interaction between the downstream evolution of the helicoidal tip vortices and the alternate vortex shedding from the turbine tower. The LES dataset is interrogated through different modal decomposition techniques, such as proper orthogonal decomposition and dynamic mode decomposition. The dominant wake dynamics are selected for the formulation of a reduced order model, which consists in a linear time-marching algorithm where temporal evolution of flow dynamics is obtained from the previous temporal realization multiplied by a time-invariant operator.This article is part of the themed issue 'Wind energy in complex terrains'.

Abstract
YKL-40 (also called chitinase 3-like-1 or human cartilage glycoprotein 39) is a chitinase-like protein belonging to the family 18 of glycosyl hydrolase (GH18). This protein is involved in the inflammatory process acting as pro-inflammatory cytokine secreted by neutrophils, activated human macrophages, vascular smooth muscle cells and cancer cells. It has been shown that YKL-40 has a role in pathological tissue remodeling and development of fibrosis of several diseases. To date, the biological and pathophysiological function of YKL-40 protein in pulmonary diseases is still unclear. This review focuses on the role of YKL-40 in diagnosis and monitoring of different lung diseases in order to assess whether this protein could be used as biomarker of specific conditions featured by inflammation and fibrosis. A comprehensive review of the literature using PubMed database, with appropriate terms, was undertaken for articles in English published since 1997. The literature search was undertaken in October 2014.

Abstract
In recent decades, there has been an increase in the prevalence of asthma and obesity in pediatric age. In this regard several studies have provided controversial data to demonstrate the link between Body Mass Index (BMI) and asthma, both in adults and in children. In this prospective study we evaluated the relationship between body mass index value, total IgE immunoglobulin E levels, skin prick test (SPT) sensitization and lung function in children affected by asthma. According to the analysis of data on the comparison of normal-weight patients versus overweight/obese patients, there was no significant difference in the values of FEV1 (86%±12 vs 90%±19), FVC (81%±11 vs 88%±18), skin prick tests (22.72% vs 36.66%) and total IgE values (192.22±368.28 vs 503±914.04). We carried out a sub-analysis to study the difference between three groups of patients: normal weight, overweight and obese. Obese patients showed higher total IgE values than normal-weight patients with a statistically significant difference. Conversely, there was no significant difference between the normal weight group and the obese group in the respiratory function tests and the SPT. Moreover, we found a higher value of total IgE in female overweight/obese compared with normal weight, while there was no significant difference in relation to parameters of lung function and SPT. However, the same analysis in the male sample did not show any statistically significant difference. This study confirms the higher incidence of atopy in obese children, especially in female gender, but not a direct relationship with either allergens sensitization or abnormal lung function.

Abstract
Asthma is one of the most common chronic diseases in children. To date the diagnosis of asthma is mainly clinical, based on the clinical history, a careful physical examination and lung function tests. However, symptoms are often not specific and lung function tests are not very sensitive. In order to find a solution to this problem new biomarkers of airway inflammation are being developed. YKL-40 is a chitinase-like protein that has a role in the inflammation and tissue remodeling in several human diseases. The aim of this study is to evaluate serum levels of YKL40 in children with intermittent or persistent asthma. We performed a cross-sectional analysis of serum samples from a cohort of patients with asthma and healthy controls. Patients with asthma were stratified according to four levels of asthma severity (mild intermittent, mild persistent, moderate persistent, and severe persistent). The analysis of serum samples was performed with the use of a commercially available enzyme-linked immune-adsorbent assay (ELISA) kit (Quidel). The minimum detection limit of the assay for YKL-40 is 15.6 ng per milliliter (ng/ml). Our data showed that circulating YKL-40 levels are significantly higher in patients with asthma than healthy subjects (36±18.6 vs 14:41±2.88, p= 0.001). Furthermore, we found significantly higher values of YKL-40 in both groups of children with intermittent asthma (p less than 0.001) and persistent asthma (p less than 0.001) than healthy controls. However, no correlation was found with duration and severity of asthmatic disease (r = 0:18, p= 0:33, r = 0.28 P = 0:13, respectively). Our data allow us to suggest that YKL-40 represents a useful biomarker of asthma in children with intermittent or persistent asthma.

Abstract
Asthma is characterized by chronic inflammation of airways. Currently, no traditional method allows an easy daily evaluation of the degree of airway inflammation. Measuring inflammatory biomarkers in the breath is a very attractive approach to monitor asthma inflammation. In recent years, the measurement of exhaled breath temperature (EBT) has been proposed as a method capable of detecting the inflammatory status of the airways. The objective of this study is to strengthen the role of EBT in the diagnosis and monitoring of asthma. The study sample was represented by a group of 40 patients, of both sexes, aged 6-15 years. The elective criteria for submitting patients to EBT determination were abstaining from drugs in the preceding 24 h, fasting for at least 2 h, physical resting for at least 30 minutes, a body temperature between 35-37°C. The temperature in the room of the surveys ranged from 18 to 25°C. The EBT values of asthmatic patients were higher [(median (IQR): 29.77°C (30.67°C to 29.38°C) range 28.46°C min-max 34.78°C] than those of non-asthmatic ones (median (IQR): 28.22°C (29.09°C-27.7°C), range 27.09°C min-max 30.07°C] and this difference was highly significant (p less than 0.001). Furthermore, no significant difference was found between the EBT values of the following groups of patients: those exposed and not exposed to passive smoking, those receiving and not receiving leukotriene drugs, those receiving and not receiving specific immunotherapy, monoallergic patients and poliallergic ones, those sensitized and not sensitized to house dust, perennial allergic patients and seasonal allergic ones. In addition, the evaluation of the correlation of EBT values with body temperature (r=0.119, p=0.464) and ambient temperature (r=-304, p = 0.057) did not show any significant correlation. Finally, no statistically significant correlation was demonstrated between EBT values and FEV1 (r=-0055, p=0.81, Fig. 4). In conclusion, the data of the present study further support the hypothesis that EBT can be considered a good method for monitoring asthma.

Abstract
Nephrotic syndrome is a condition of massive proteinuria that leads to hypoalbuminaemia and oedema. In the pediatric age, the most common form of nephrotic syndrome is childhood idiopathic nephrotic syndrome (CINS). Although the etiological mechanisms underlying CINS are still unclear, the disease is considered to be immune-mediated. Several studies have previously reported a possible association between CINS and atopy, with the latter defined as abnormal immunoglobulin-E response on the background of a T-helper 2 (Th2)-driven immune system. In fact, both experimental and clinical studies have suggested that idiopathic nephrotic syndrome can be associated and/or triggered by a wide array of atopic diseases, though this remains a highly controversial topic. Exposure to inhalant-allergens (and/or introduction of food-allergens) has been previously correlated with the onset and/or the relapse of CINS in some children and a significant worse response to steroid therapy has been also described in reports of CINS associated to concomitant atopic diseases. In this review, we analyzed previous studies with the aim to clarify, basing on the existent literature, the association between atopy and idiopathic nephrotic syndrome. Additionally, we also speculated on the underlying immunological pathways that could potentially make some children prone to both CINS and atopic diseases.

Abstract
The aim of this randomized open study was to evaluate the safety and efficacy of different dosages (2000 UI vs 4000 UI) of sublingual immunotherapy (SLIT) in patients with allergic diseases such as asthma associated to rhinitis and rhinoconjunctivitis sensitized to house dust mites. We enrolled 61 patients with a history of allergic asthma, and a positive skin prick test for Dermatophagoides (D.) pteronyssinus/farinae. Patients were randomly assigned to receiving SLIT at dosage of 2000 UI (Group A) or 4000 UI (Group B) maintenance dose. We evaluated: subjective symptoms using a Visual Analogic Scale (VAS), the amount of prescribed symptomatic drugs, bronchial reactivity to methacoline and side effects using a specific questionnaire. A significant improvement in symptoms, assessed by VAS, was observed with both SLIT doses with no significant differences between groups. The provocation dose of methacoline inducing a 20% fall of FEV1 significantly increased after 12 months only in the 4000 UI dose group. In conclusion, both monomeric allergoid dosages of SLIT (2000 UI and 4000 UI) are a safe and efficacy option to reduce symptoms in patients with allergic asthma caused by house dust mites. Moreover, both dosages are efficacious even to protect against airway reactivity but it seems that monomeric allergoid of SLIT at higher dosage (4000 UI) is better than at the lower dosage (2000 UI).

Abstract
BACKGROUND AND AIMS Ulmus minor has been severely affected by Dutch elm disease (DED). The introduction into Europe of the exotic Ulmus pumila, highly tolerant to DED, has resulted in it widely replacing native U. minor populations. Morphological and genetic evidence of hybridization has been reported, and thus there is a need for assessment of interspecific gene flow patterns in natural populations. This work therefore aimed at studying pollen gene flow in a remnant U. minor stand surrounded by trees of both species scattered across an agricultural landscape. METHODS All trees from a small natural stand (350 in number) and the surrounding agricultural area within a 5-km radius (89) were genotyped at six microsatellite loci. Trees were morphologically characterized as U. minor, U. pumila or intermediate phenotypes, and morphological identification was compared with Bayesian clustering of genotypes. For paternity analysis, seeds were collected in two consecutive years from 20 and 28 mother trees. Maximum likelihood paternity assignment was used to elucidate intra- and interspecific gene flow patterns. KEY RESULTS Genetic structure analyses indicated the presence of two genetic clusters only partially matching the morphological identification. The paternity analysis results were consistent between the two consecutive years of sampling and showed high pollen immigration rates (∼0·80) and mean pollination distances (∼3 km), and a skewed distribution of reproductive success. Few intercluster pollinations and putative hybrid individuals were found. CONCLUSIONS Pollen gene flow is not impeded in the fragmented agricultural landscape investigated. High pollen immigration and extensive pollen dispersal distances are probably counteracting the potential loss of genetic variation caused by isolation. Some evidence was also found that U. minor and U. pumila can hybridize when in sympatry. Although hybridization might have beneficial effects on both species, remnant U. minor populations represent a valuable source of genetic diversity that needs to be preserved.

Abstract
Airway inflammation plays a central role in cystic fibrosis (CF) lung disease, and biomarkers of inflammation, such as high-mobility group box 1 (HMGB1) could be used to monitor disease activity. The main aim of this study was to confirm the role of HMGB1 in CF patients, correlating its serum and sputum levels with pulmonary function and inflammation. Serum and sputum HMGB1 were evaluated in a cohort of 31 CF patients and 30 non-smoking healthy subjects (HS group). Acute pulmonary exacerbation events and lung function decline have been also evaluated during a 3-year follow-up period. Serum HMGB1 levels were significantly higher than those measured in HS, such as sputum HMGB1. Kaplan-Meier survival curves revealed that patients with high HMGB1 values experienced a significantly faster evolution to decline of lung function. A multiple Cox regression analysis assessed that an increase of serum HMGB1 was associated with 5% increased risk of pulmonary disease progression, whereas elevated sputum HMGB1 was related to a 10% increased risk of lung function decline. In CF patients, HMGB1 closely reflects the entity of pulmonary impairment and represents a strong and independent risk marker for progression of lung function decline.

Abstract
International asthma guidelines recommend increasing the dose of ICS or adding leukotriene modifiers or the use of long-acting inhaled beta2-agonists (LABAs) in combination with inhaled corticosteroids (ICS) when uncontrolled asthma occurs in adult and children in treatment with low-dose inhaled corticosteroids. However, in children, the effects of this last treatment option are unclear because there are few studies on the efficacy and safety of these drugs in pediatric age. Furthermore, salmeterol is licensed for use in children over 4 years and formoterol in children of more than 6 years. Finally, recent data provides evidence that repeated bronchoconstriction induces epithelial cell stress that may lead to remodeling and these findings may have potential implications for asthma management, particularly for LABAs treatment in the future.

Abstract
Precise calving monitoring is important for reducing the effects of dystocia in cows and calves. The C6 birth control system is an electronic device that detects the time of the expulsion phase during calving. Several 53 Holstein were fitted on Day 280 ± 5 of gestation with the C6 birth control system, which was left in place until confirmation of calving. Sensitivity and PPV of the system were calculated as 100 and 95%, respectively. The partum events occurring at the group fitted with the system where compared with the analogous occurred at 59 animals without device. When alarmed by the system farm staff were in the calving barn during the expulsion phase in 100% of cases. On the contrary the cows without the device were assisted only in 17% of cases (P < 0.001).

Abstract
Allergic rhinitis is characterized by local inflammation. Nasal lavage may be a useful treatment, however, there are few studies on this topic. This study aims to evaluate the effects of Ischia thermal water nasal irrigation on allergic rhinitis symptoms and airway inflammation during the period of natural exposure to Parietaria pollen in children with allergic rhinitis and intermittent asthma. Forty allergic children were randomly divided into two groups: the first group (Group 1) practiced crenotherapy with thermal water aerosol for 15 days per month, for three consecutive months, the control group (Group 2) was treated with 0.9% NaCl (isotonic) solution. In addition, all children were treated with cetirizine (0.5 gtt./kg/day once daily). Nasal symptom assessment, including Total Symptom Score (TSS), spirometry, and exhaled nitric oxide (FeNO) were considered before the treatment (T0), at the end of the treatment (T1) and again 2 weeks after the end of the treatment (T2). The study was registered in the Clinical Trials.gov (NCT01326247). Thermal water significantly reduced both TSS and FeNO levels and there was a significant relationship between reduction of nasal symptoms and FeNO values at the end of treatment with thermal water. In conclusion, this study shows that nasal crenotherapy with the hypermineral chloride-sodium water of Ischia was effective in children with seasonal allergic rhinitis based on the sensitivity to Parietaria. These results demonstrate that this natural treatment may be effective in a common and debilitating disease such as the allergic rhinitis.

Abstract
The study of the dispersal capability of a species can provide essential information for the management and conservation of its genetic variability. Comparison of gene flow rates among populations characterized by different management and evolutionary histories allows one to decipher the role of factors such as isolation and tree density on gene movements. We used two paternity analysis approaches and different strategies to handle the possible presence of genotyping errors to obtain robust estimates of pollen flow in four European beech (Fagus sylvatica L.) populations from Austria and France. In each country one of the two plots is located in an unmanaged forest; the other plots are managed with a shelterwood system and inside a colonization area (in Austria and France, respectively). The two paternity analysis approaches provided almost identical estimates of gene flow. In general, we found high pollen immigration (~75% of pollen from outside), with the exception of the plot from a highly isolated forest remnant (~50%). In the two unmanaged plots, the average within-population pollen dispersal distances (from 80 to 184 m) were higher than previously estimated for beech. From the comparison between the Austrian managed and unmanaged plots, that are only 500 m apart, we found no evidence that either gene flow or reproductive success distributions were significantly altered by forest management. The investigated phenotypic traits (crown area, height, diameter and flowering phenology) were not significantly related with male reproductive success. Shelterwood seems to have an effect on the distribution of within-population pollen dispersal distances. In the managed plot, pollen dispersal distances were shorter, possibly because adult tree density is three-fold (163 versus 57 trees per hectare) with respect to the unmanaged one.

Abstract
PTX3 behaves as an acute-phase response protein as its blood levels rapidly and dramatically increase during endotoxic shock, sepsis, and other inflammatory and infectious conditions. Therefore, this study was designed to investigate a possible role of PTX3 in children with Atopic Dermatitis (AD). One-hundred-and-thirty-six patients (37 females, 99 males, mean age 10.4 years) were enrolled in the study. One hundred patients (74%) had only respiratory symptoms (allergic rhinitis and/or bronchial asthma); thirty-six patients (26%) showed dermatitis associated with respiratory allergy (allergic rhinitis and/or bronchial asthma). PTX3 levels were higher in children with AD and there was a significant correlation between serum PTX3 levels and SCORAD index (p-value=0.0001, rho=0.658). Therefore, this study may show that PTX3 might be a reliable marker for the severity of AD in children with respiratory allergy.

Abstract
Recently, there has been considerable interest in the relationship between allergic and autoimmune diseases. We evaluated the prevalence of thyroid autoimmunity in 566 children affected by atopic dermatitis (AD), urticaria, rhinitis, chronic cough, and asthma. Our results suggest that allergy and autoimmunity can be two potential outcomes of dysregulated immunity. It is tempting to speculate that NK Th2 cells can favour asthma onset and at the same time improve thyroid autoimmunity.
