RESUMO
Long pentraxin 3 (PTX3) is an essential component of humoral innate immunity, involved in resistance to selected pathogens and in the regulation of inflammation1-3. The present study was designed to assess the presence and significance of PTX3 in Coronavirus Disease 2019 (COVID-19)4-7. RNA-sequencing analysis of peripheral blood mononuclear cells, single-cell bioinformatics analysis and immunohistochemistry of lung autopsy samples revealed that myelomonocytic cells and endothelial cells express high levels of PTX3 in patients with COVID-19. Increased plasma concentrations of PTX3 were detected in 96 patients with COVID-19. PTX3 emerged as a strong independent predictor of 28-d mortality in multivariable analysis, better than conventional markers of inflammation, in hospitalized patients with COVID-19. The prognostic significance of PTX3 abundance for mortality was confirmed in a second independent cohort (54 patients). Thus, circulating and lung myelomonocytic cells and endothelial cells are a major source of PTX3, and PTX3 plasma concentration can serve as an independent strong prognostic indicator of short-term mortality in COVID-19.

OBJECTIVE: Achieving remission in severe asthma holds paramount importance in elevating patient quality of life and reducing both individual and societal burdens associated with this chronic condition. This study centers on identifying pivotal patient-relevant endpoints through standardized, reproducible methods, while also developing a patient-centric definition of remission, essential for effective disease management. METHODS: A discrete choice experiment (DCE) was conducted to assess patients' perceptions on the four primary criteria for defining severe asthma remission, as outlined by the SANI survey. Additionally, it investigated the correlation between these perceptions and improvements in the doctor-patient therapeutic alliance during treatment decision-making. RESULTS: 249 patients (70% aged between 31-60, 59% women and 82% without other pathologies requiring corticosteroids) prioritize the use of oral corticosteroids (OCS, 48%) and the Asthma Control Test (ACT, 27%) in defining their condition, ranking these above lung function and exacerbations. This preference for OCS stems from its direct role in treatment, tangible tracking, immediate symptom relief, and being a concrete measure of disease severity compared to the less predictable and quantifiable exacerbations. CONCLUSIONS: This study explores severe asthma remission from patients' perspectives using clinician-evaluated parameters. The DCE revealed that most patients highly value OCS and the ACT, prefer moderate improvement, and avoid cortisone cycles. No definitive preference was found for lung function status. Integrating patient-reported information with professional insights is crucial for effective management and future research. Personalized treatment plans focusing on patient preferences, adherence, and alternative therapies aim to achieve remission and enhance quality of life.
RESUMO
BACKGROUND: Robotic-assisted laparoscopic radical prostatectomy (RALP) requires pneumoperitoneum and steep Trendelenburg position. Our aim was to investigate the influence of the combination of pneumoperitoneum and Trendelenburg position on mechanical power and its components during RALP. METHODS: Sixty-one prospectively enrolled patients scheduled for RALP were studied in supine position before surgery, during pneumoperitoneum and Trendelenburg position and in supine position after surgery at constant ventilatory setting. In a subgroup of 17 patients the response to increasing positive end-expiratory pressure (PEEP) from 5 to 10 cmH2O was studied. RESULTS: The application of pneumoperitoneum and Trendelenburg position increased the total mechanical power (13.8 [11.6 - 15.5] vs 9.2 [7.5 - 11.7] J/min, p < 0.001) and its elastic and resistive components compared to supine position before surgery. In supine position after surgery the total mechanical power and its elastic component decreased but remained higher compared to supine position before surgery. Increasing PEEP from 5 to 10 cmH2O within each timepoint significantly increased the total mechanical power (supine position before surgery: 9.8 [8.4 - 10.4] vs 12.1 [11.4 - 14.2] J/min, p < 0.001; pneumoperitoneum and Trendelenburg position: 13.8 [12.2 - 14.3] vs 15.5 [15.0 - 16.7] J/min, p < 0.001; supine position after surgery: 10.2 [9.4 - 10.7] vs 12.7 [12.0 - 13.6] J/min, p < 0.001), without affecting respiratory system elastance. CONCLUSION: Mechanical power in healthy patients undergoing RALP significantly increased both during the pneumoperitoneum and Trendelenburg position and in supine position after surgery. PEEP always increased mechanical power without ameliorating the respiratory system elastance.
RESUMO
BACKGROUND: The efficacy of benralizumab has been broadly demonstrated in severe eosinophilic asthma (SEA), but only few real-life studies evaluated its long-term effects. Here we present novel data from the ANANKE study in which a large cohort of SEA patients was treated for up to 96 weeks. METHODS: ANANKE (NCT04272463) is an observational retrospective Italian study investigating the key characteristics of SEA patients (collected during the 12 months prior to benralizumab initiation) and the clinical outcomes during benralizumab treatment (annual exacerbation rate [AER], lung function, asthma control, OCS use, healthcare resource utilization). A post hoc analysis was also conducted in groups of patients based on history of previous biologic therapy (bio-experienced versus naïve patients). Analyses were descriptive only. RESULTS: Before benralizumab initiation, evaluable SEA patients (N = 162, 61.1% females, mean age 56.0 ± 12.7) showed a median blood eosinophil count (BEC) of 600 cells/mm3 (IQR: 430-890). Patients experienced frequent exacerbations (annualized exacerbation rate [AER]: 4.10, severe AER: 0.98), with impaired lung function and poor asthma control (median ACT score: 14) despite 25.3% reported oral corticosteroid (OCS) use. Nasal polyposis was present in 53.1% patients; 47.5% patients were atopic. After 96 weeks since the start of benralizumab, nearly 90% patients were still on treatment; benralizumab dramatically decreased exacerbations (AER: - 94.9%; severe AER: - 96.9%), improved respiratory parameters (median increase in pre-bronchodilator forced expiratory volume [pre-BD FEV1]: + 400 mL) and asthma control (median ACT score: 23) while eliminating OCS in 60% patients. Importantly, benralizumab effects were either maintained or progressively improved over time, accompanied by a nearly complete depletion of BEC. Benralizumab reduced AER both in naïve (any AER: - 95.9%; severe AER: - 97.5%) and bio-experienced patients (any AER: - 92.4%; severe AER: - 94.0%). CONCLUSIONS: Profound and sustained improvements in all asthma outcomes were observed with benralizumab. The correct identification of patients' eosinophilic-driven asthma phenotype was essential to ensure the achievement of such remarkable results.

OBJECTIVE: Exercise capacity, daily physical activity, and psychological profile are crucial aspects in the management of asthmatic patients. Whether these features are expressed in a different way in mild-moderate (MMA) and severe asthma (SA) is unknown. METHODS: In this observational cross-sectional study, patients matching the American Thoracic Society/European Respiratory Society (ATS/ERS) definition for SA underwent incremental cardiopulmonary exercise testing (CPET), full lung function testing, and an evaluation of daily step count and physical activity. Questionnaires on quality of life, general fatigue, and presence of anxiety and depression traits (Hospital Anxiety and Depression Scale - HADS) were administered. Patients were compared with a cohort of age- and gender-matched MMA patients. RESULTS: We enrolled 16 SA, 17 MMA patients, and 16 healthy subjects. Compared to MMA, SA subjects showed a median (interquartile range) reduced peak oxygen consumption during CPET (20.4 (17.2-23.3) vs. 25.6 (18.5-30.3) ml/min/kg; p = 0.019), a reduced resting lung function (FEV1% of predicted 77 (67-84) vs. 96 (84-100); p < 0.001) and a pronounced anxiety trait at HADS (9.5 (3-11.7) vs. 4.0 (2.0-7.5); p = 0.023). In addition, SA patients showed a significantly higher reduction in inspiratory capacity from rest to peak (310 (160-520) vs. 110 (-65-325) ml; p = 0.031). We found no significant differences in mean daily step count or quality of life. CONCLUSIONS: Compared to MMA, SA patients present a reduced exercise capacity and a more pronounced anxiety trait, but not worse daily physical activity or quality of life. These aspects should be considered in the clinical management and research development of SA.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) primarily affects old patients. Old age is a predictor of mortality. Nintedanib, the only antifibrotic drug approved in Italy for patients aged >80 years, can slow the progression of IPF by reducing the rate of decline in forced vital capacity (FVC) and the risk of exacerbations. OBJECTIVES: The primary aim of the study was to compare the decline of FVC after 12 months of nintedanib in patients aged >80 years versus younger patients. Differences related to other functional data, safety, tolerability, hospitalizations, exacerbations, and mortality were evaluated. METHODS: An observational, retrospective, multicenter study was carried out in Italy. RESULTS: 159 (122 [76.7%] males) patients were recruited: 106 (66.7%) aged ≤80 years and 53 (33.3%) aged >80 years. FVC decline after 12 months of therapy was not significantly different (-45 mL [-170; 75] vs. -20 mL [-138; 110] mL; p: 0.51). No differences were found for other functional data. Diarrhea was the most frequent adverse event (AE). Rate and type of any AEs, permanent/temporary dose reduction, or drug discontinuation were not significantly different between patients aged ≤80 vs. >80 years. Furthermore, acute exacerbations, hospitalization, and mortality were not significantly different. CONCLUSIONS: Nintedanib is effective and safe in patients with IPF aged >80 years, and no significant differences were found when clinical outcomes were compared with those of younger patients. Thus, older age should not be a barrier for the early prescription of antifibrotic treatment in IPF patients.

BACKGROUND: Data from phase 3 trials have demonstrated the efficacy and safety of benralizumab in patients with severe eosinophilic asthma (SEA). We conducted a real-world study examining the baseline characteristics of a large SEA population treated with benralizumab in clinical practice and assessed therapy effectiveness. METHODS: ANANKE is an Italian multi-center, retrospective cohort study including consecutive SEA patients who had started benralizumab therapy ≥ 3 months before enrolment (between December 2019 and July 2020), in a real-world setting. Data collection covered (1) key patient features at baseline, including blood eosinophil count (BEC), number and severity of exacerbations and oral corticosteroid (OCS) use; (2) clinical outcomes during benralizumab therapy. We also conducted two post-hoc analyses in patients grouped by body mass index and allergic status. Analyses were descriptive only. RESULTS: Of 218 patients with SEA enrolled in 21 Centers, 205 were evaluable (mean age, 55.8 ± 13.3 years, 61.5% females). At treatment start, the median BEC was 580 cells/mm3 (interquartile range [IQR]: 400-850); all patients were on high-dose inhaled controller therapy and 25.9% were on chronic OCS (median dose: 10 mg/die prednisone-equivalent [IQR: 5-25]); 92.9% experienced ≥ 1 exacerbation within the past 12 months (annualized exacerbation rate [AER] 4.03) and 40.3% reported ≥ 1 severe exacerbation (AER 1.10). During treatment (median duration: 9.8 months [IQR 6.1-13.9]; ≥ 12 months for 34.2% of patients), complete eosinophil depletion was observed; exacerbation-free patients increased to 81% and only 24.3% reported ≥ 1 severe event. AER decreased markedly to 0.27 for exacerbations of any severity (- 93.3%) and to 0.06 for severe exacerbations (- 94.5%). OCS therapy was interrupted in 43.2% of cases and the dose reduced by 56% (median: 4.4 mg/die prednisone-equivalent [IQR: 0.0-10.0]). Lung function and asthma control also improved. The effectiveness of benralizumab was independent of allergic status and body mass index. CONCLUSIONS: We described the set of characteristics of a large cohort of patients with uncontrolled SEA receiving benralizumab in clinical practice, with a dramatic reduction in exacerbations and significant sparing of OCS. These findings support benralizumab as a key phenotype-specific therapeutic strategy that could help physicians in decision-making when prescribing biologics in patients with SEA.

BACKGROUND: Coronavirus disease 2019-associated acute respiratory distress syndrome (COVID-19 ARDS) seems to differ from the "classic ARDS", showing initial significant hypoxemia in the face of relatively preserved compliance and evolving later in a scenario of poorly compliant lungs. We tested the hypothesis that in patients with COVID-19 ARDS, the initial value of static compliance of respiratory system (Crs) (1) depends on the previous duration of the disease (i.e., the fewer days of illness, the higher the Crs and vice versa) and (2) identifies different lung patterns of time evolution and response to prone positioning. METHODS: This was a single-center prospective observational study. We enrolled consecutive mechanically ventilated patients with a diagnosis of COVID-19 who met ARDS criteria, admitted to intensive care unit (ICU). Patients were divided in four groups based on quartiles of initial Crs. Relationship between Crs and the previous duration of the disease was evaluated. Respiratory parameters collected once a day and during prone positioning were compared between groups. RESULTS: We evaluated 110 mechanically ventilated patients with a diagnosis of COVID-19 who met ARDS criteria admitted to our ICUs. Patients were divided in groups based on quartiles of initial Crs. The median initial Crs was 41 (32-47) ml/cmH2O. No association was found between the previous duration of the disease and the initial Crs. The Crs did not change significantly over time within each quartile. Positive end-expiratory pressure (PEEP) and driving pressure were respectively lower and greater in patients with lower Crs. Prone positioning significantly improved PaO2/FiO2 in the 4 groups, however it increased the Crs significantly only in patients in lower quartile of Crs. CONCLUSIONS: In our cohort, the initial Crs is not dependent on the previous duration of COVID-19 disease. Prone positioning improves oxygenation irrespective to initial Crs, but it ameliorates respiratory mechanics only in patients with lower Crs.

Senescence is a stress-response process characterized by the irreversible inhibition of cell proliferation, associated to the acquisition of a senescence-associated secretory phenotype (SASP), that may drive pathological conditions. Lymphangioleiomyomatosis (LAM) is a rare disease in which LAM cells, featuring the hyperactivation of the mammalian Target of Rapamycin Complex 1 (mTORC1) for the absence of tuberin expression, cause the disruption of the lung parenchyma. Considering that LAM cells secrete SASP factors and that mTOR is also a driver of senescence, we deepened the contribution of senescence in LAM cell phenotype. We firstly demonstrated that human primary tuberin-deficient LAM cells (LAM/TSC cells) have senescent features depending on mTOR hyperactivation, since their high positivity to SA-ß galactosidase and to phospho-histone H2A.X are reduced by inducing tuberin expression and by inhibiting mTOR with rapamycin. Then, we demonstrated the capability of LAM/TSC cells to induce senescence. Indeed, primary lung fibroblasts (PLFs) grown in LAM/TSC conditioned medium increased the positivity to SA-ß galactosidase and to phospho-histone H2A.X, as well as p21WAF1/CIP1 expression, and enhanced the mRNA expression and the secretion of the SASP component IL-8. Taken together, these data make senescence a novel field of study to understand LAM development and progression.

The aim of our study is to evaluate the accuracy of CURB-65 and Pneumonia Severity Index (PSI), the most widely used scores for community acquired pneumonia, and MuLBSTA, a viral pneumonia score, in predicting 28-day mortality in Coronavirus Disease 2019 (COVID-19) pneumonia.We retrospectively collected clinical data of consecutive patients with laboratory-confirmed COVID-19 pneumonia admitted at Papa Giovanni XXIII Hospital from February 23rd to March 14th, 2020. We calculated at Emergency Department (ED) presentation CURB-65, PSI and MuLBSTA and we compared their performances in discriminating between survivors and non-survivors at 28 days. Among 431 hospitalized patients, the majority presented with hypoxic respiratory failure: median (interquartile range, IQR) PaO2/FiO2 ratio at admission was 228.6 (142.0-278.1). In the first 24 hours, 111 (27%) patients were administered low-flow oxygen cannula, 50 (12%) Venturi Mask, 95 (23%) non-rebreather mask, 106 (26%) non-invasive ventilation, 12 (3%) mechanical ventilation and 41 (9%) were not administered oxygen therapy. Mortality rate at 28-day was 35% (150/431). Between survivors and non-survivors, median (IQR) scores were, respectively, 1.0 (1.0-2.0) and 2.0 (2.0-3.0) for CURB-65 (p<0.001); 90.5 (76.0-105.5) and 115.0 (100.0-129.0) for PSI (p<0.001); 7.0 (5.0-10.0) and 11.0 (9.0-13.0) for MuLBSTA (p<0.001). Areas under the receiver operating characteristic curve (AUCs) for each score were, respectively, 0.725 (0.662-0.787), 0.776 (0.693-0.859) and 0.743 (0.680-0.806) (p>0,05). PSI and MuLBSTA did not show a better performance when compared to CURB-65. Although CURB-65, PSI and MuLBSTA scores are useful tools to discriminate between survivors and non-survivors in COVID-19 pneumonia, their diagnostic accuracy in discriminating 28-day mortality in COVID-19 pneumonia is moderate, as confirmed by AUCs <0.80, and there is a potential underestimation of disease severity in the low-risk classes. For this reason, they should not be recommended in ED to decide between inpatient and outpatient management in patients affected by COVID-19 pneumonia.

Asthma is a chronic respiratory disease in which airway inflammation is a key feature, even in the milder expressions of the disease. The conventional pharmacological approach to mild asthma has long relied on reliever therapy with as-needed short-acting beta-agonists (SABAs), while anti-inflammatory maintenance with inhaled corticosteroids (ICSs) has been reserved for patients with more persistent asthma. Poor adherence to maintenance treatment is an important issue in asthma management, and can partly explain suboptimal symptom control. Over-reliance on SABA bronchodilators for rapid symptom relief is common in real life and potentially leads to an increased risk of asthma morbidity and mortality. Combined anti-inflammatory and reliever medications in a single inhaler have the potential to overcome these limitations. Recent studies in patients with mild asthma have shown that anti-inflammatory reliever therapy with budesonide-formoterol, given on an as-needed basis, is superior to SABA in ensuring asthma control and non-inferior to budesonide maintenance therapy in preventing exacerbations. To address the implications of these important findings for the management of patients with asthma, Italian specialists convened at a series of meetings held during the second half of 2018 across Italy. This article presents their position on these topics and includes a review of the evidence supporting the use of anti-inflammatory reliever therapy in mild asthma and the implementation of this novel approach in clinical practice.

OBJECTIVES: To evaluate the inter-rater agreement of chest X-ray (CXR) findings in coronavirus disease 2019 (COVID-19) and to determine the value of initial CXR along with demographic, clinical, and laboratory data at emergency department (ED) presentation for predicting mortality and the need for ventilatory support. METHODS: A total of 340 COVID-19 patients who underwent CXR in the ED setting (March 1-13, 2020) were retrospectively included. Two reviewers independently assessed CXR abnormalities, including ground-glass opacities (GGOs) and consolidation. Two scoring systems (Brixia score and percentage of lung involvement) were applied. Inter-rater agreement was assessed by weighted Cohen's kappa (κ) or intraclass correlation coefficient (ICC). Predictors of death and respiratory support were identified by logistic or Poisson regression. RESULTS: GGO admixed with consolidation (n = 235, 69%) was the most common CXR finding. The inter-rater agreement was almost perfect for type of parenchymal opacity (κ = 0.90), Brixia score (ICC = 0.91), and percentage of lung involvement (ICC = 0.95). The Brixia score (OR: 1.19; 95% CI: 1.06, 1.34; p = 0.003), age (OR: 1.16; 95% CI: 1.11, 1.22; p < 0.001), PaO2/FiO2 ratio (OR: 0.99; 95% CI: 0.98, 1; p = 0.002), and cardiovascular diseases (OR: 3.21; 95% CI: 1.28, 8.39; p = 0.014) predicted death. Percentage of lung involvement (OR: 1.02; 95% CI: 1.01, 1.03; p = 0.001) and PaO2/FiO2 ratio (OR: 0.99; 95% CI: 0.99, 1.00; p < 0.001) were significant predictors of the need for ventilatory support. CONCLUSIONS: CXR is a reproducible tool for assessing COVID-19 and integrates with patient history, PaO2/FiO2 ratio, and SpO2 values to early predict mortality and the need for ventilatory support. KEY POINTS: ⢠Chest X-ray is a reproducible tool for assessing COVID-19 pneumonia. ⢠The Brixia score and percentage of lung involvement on chest X-ray integrate with patient history, PaO2/FIO2 ratio, and SpO2 values to early predict mortality and the need for ventilatory support in COVID-19 patients presenting to the emergency department.

OBJECTIVE: To investigate whether the decrease in dyspnea in neuromuscular diseases after air stacking (AS) occurs mostly in patients with decreased inspiratory muscle force and ensuing chest wall restriction or heterogeneous ventilation across the lungs. DESIGN: Interventional, before-after study. SETTING: A neurorehabilitation inpatient and outpatient center. PARTICIPANTS: Fifteen consecutive adult patients affected by neuromuscular diseases (N=15). INTERVENTIONS: AS treatment. MAIN OUTCOME MEASURES: Patients had vital capacity (VC) and sniff nasal inspiratory pressure (SNIP) measured. We measured Borg score, oxygen saturation, and ventilation heterogeneity across the lung as estimated from the difference between respiratory resistance at 5 and 19 Hz (R5-19) with the forced oscillation technique before and 5, 30, 60, and 120 minutes after applying AS. RESULTS: Before AS, Borg score was significantly related to R5-19 (r2 0.46, P<.05) but not to VC % predicted, SNIP % predicted, and time since symptom onset. After AS, average Borg score gradually decreased (P=.005), whereas inspiratory flow resistance at 5 Hz, R5-19, and inspiratory reactance at 5 Hz tended to improve, despite not reaching statistical significance. The decrease in dyspnea at 60 and 120 minutes after AS significantly correlated with baseline R5-19 (r2 0.49, P<.01 and r2 0.29, P<.05, respectively), but not with VC % predicted, SNIP % predicted, time since symptom onset, and clinical severity score for patients affected by amyotrophic lateral sclerosis. CONCLUSIONS: These findings suggest that dyspnea in neuromuscular diseases is related to heterogeneous ventilation rather than inspiratory muscle force and/or lung volumes decrease. Restoring ventilation distribution across the lungs with AS appears to improve dyspnea.

BACKGROUND: Disease awareness is a challenge in the management of chronic obstructive pulmonary disease (COPD). OBJECTIVES: The aim of this analysis was to explore the association between COPD optimal and suboptimal awareness, clinical parameters, and the following patient-reported outcomes: modified Medical Research Council (mMRC), Treatment Satisfaction Questionnaire (TSQM-9), COPD Assessment Test (CAT), Morisky Medication-Taking Adherence Scale (MMAS-4), and Brief Illness Perception Questionnaire (B-IPQ). METHODS: This post hoc analysis of the SAT study included all enrolled patients for whom awareness (Disease Awareness in COPD Questionnaire - DACQ) was assessed at baseline and 12 months. DACQ scores ≥80 were considered an indicator of an optimal awareness. RESULTS: 367 patients (25.8% women, median age 72 years) were included in the analysis. At enrollment, 74 patients (20.2%) had a DACQ score ≥80. Patients with suboptimal awareness, compared to those in which awareness was optimal, had higher median scores for CAT (p = 0.0001) and mMRC (p = 0.0031), a lower median TSQM-9 global score (p < 0.0001), and higher median B-IPQ score (p < 0.0001). The proportion of patients who had exacerbations during the previous year was higher in patients with suboptimal COPD awareness than in those with DACQ score ≥80 (42.8 vs. 21.4%, p = 0.0009). During the 12-month observation period, illness perception, adherence, and treatment satisfaction were found to be independent factors significantly associated with level of disease awareness. CONCLUSION: The results of our post hoc analysis suggest that patients' awareness of their COPD disease is related to both clinical outcomes and how they perceive and manage their condition.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is a pandemic affecting all countries in the world. Italy has been particularly afflicted by the health emergency, and since the peak phase has passed, major concern regarding medium to long term complications due to COVID-19 is arising. Little is known in literature regarding thromboembolic complications once healed after COVID-19. CASE PRESENTATION: A 51-year-old patient recovered from COVID-19 pneumonia complicated by pulmonary embolism (PE) came to the hospital for palpitations and chest pain. Although he was on treatment dose of direct oral anticoagulation (DOAC), massive recurrent PE was diagnosed. CONCLUSION: In the early post COVID-19 era, the question remains regarding the efficacy of DOACs in COVID-19 patients.

BACKGROUND: Gender-related factors might affect vulnerability to Covid-19. The aim of this study was to describe the role of gender on clinical features and 28-day mortality in Covid-19 patients. METHODS: Observational study of Covid-19 patients hospitalized in Bergamo, Italy, during the first three weeks of the outbreak. Medical records, clinical, radiological and laboratory findings upon admission and treatment have been collected. Primary outcome was 28-day mortality since hospitalization. RESULTS: 431 consecutive adult patients were admitted. Female patients were 119 (27.6%) with a mean age of 67.0 ± 14.5 years (vs 67.8 ± 12.5 for males, p = 0.54). Previous history of myocardial infarction, vasculopathy and former smoking habits were more common for males. At the time of admission PaO2/FiO2 was similar between men and women (228 [IQR, 134-273] vs 238 mmHg [150-281], p = 0.28). Continuous Positive Airway Pressure (CPAP) assistance was needed in the first 24 h more frequently in male patients (25.7% vs 13.0%; p = 0.006). Overall 28-day mortality was 26.1% in women and 38.1% in men (p = 0.018). Gender did not result an independent predictor of death once the parameters related to disease severity at presentation were included in the multivariable analysis (p = 0.898). Accordingly, the Kaplan-Meier survival analysis in female and male patients requiring CPAP or non-invasive ventilation in the first 24 h did not find a significant difference (p = 0.687). CONCLUSION: Hospitalized women are less likely to die from Covid-19; however, once severe disease occurs, the risk of dying is similar to men. Further studies are needed to better investigate the role of gender in clinical course and outcome of Covid-19.

Pulmonary Tumor Thrombotic Microangiopathy (PTTM) is a rare condition associated with neoplastic disorders, predominantly gastric cancer, leading to pre-capillary Pulmonary Hypertension (PH). The pathologic mechanism involved is a fibrocellular intimal proliferation of small pulmonary vessels sustained by nests of carcinomatous cells lodged in pulmonary vasculature. Clinical presentation is nonspecific, including progressive dyspnea and dry cough. Diagnosis of PTTM is extremely challenging ante-mortem and prognosis is poor. Here we describe the case of a middle-aged man, without known previous cancer history. The clinical course was rapidly unfavorable, with progressive dyspnea and PH associated with hemodynamic instability, eventually culminating in patient's death. PTTM diagnosis was made post-mortem. PTTM should be considered in any patient presenting with unexplained PH, especially if it is rapidly progressive, poorly responsive to standard approaches or there is suspected history of malignancy. A prompt diagnosis of PTTM could help in bringing light into this still under-recognized condition.

BACKGROUND: Inhaled corticosteroid (ICS)/long-acting ß2 agonist (LABA) fixed-dose combinations (FDCs) and LABA/long-acting muscarinic antagonist (LAMA) FDCs are extensively used to treat chronic obstructive pulmonary disease (COPD). The aim of the present network meta-analysis was to assess the comparative efficacy of all the currently available dual therapies in patients with moderate-to-severe COPD. METHODS: A network meta-analysis (≥3 nodes, Bayesian method) was performed by searching for randomized clinical trials (RCTs) that compared the impact of different LABA/LAMA FDCs vs. ICS/LABA FDCs on both primary and secondary endpoints. The primary endpoints were: the change from baseline in trough forced expiratory volume in 1â¯s (FEV1) and the risk of exacerbation of COPD (AECOPD). The secondary endpoints were: peak FEV1, St' George's Respiratory Questionnaire (SGRQ), Transition Dyspnea Index (TDI), and rescue medication use. RESULTS: Data of 17,734 COPD patients were extracted from 16 RCTs. The length of treatment ranged from 6 weeks to 52 weeks. All LABA/LAMA FDCs, except aclidinium/formoterol, produced a statistically significant improvement compared to ICS/LABAs in trough FEV1. The surface under the cumulative ranking curve (SUCRA) analysis indicated that umeclidinium/vilanterol, glycopyrronium/indacaterol and glycopyrrolate/formoterol fumarate were the most effective FDCs in improving trough FEV1. Across the FDCs analyzed for the risk of AECOPD, glycopyrronium/indacaterol significantly reduced the exacerbation risk compared to fluticasone propionate/salmeterol and resulted the most effective combination in the SUCRA analysis. Similar trend were also observed for the peak FEV1. No significant differences were detected across the investigated FDCs regarding SGRQ, TDI, and use of rescue medication. CONCLUSIONS: The results of this meta-analysis show that LABA/LAMA combinations are consistently more effective than ICS/LABA FDCs for most of the evaluated outcomes. However, differences have also been observed between FDCs belonging to the same class. Across the investigated LABA/LAMA FDCs, glycopyrronium/indacaterol revealed a consistent and robust efficacy profile.

Healthcare transition from childhood to adulthood is required to ensure continuity of care of an increasing number of individuals with chronic conditions surviving into adulthood. The transition for patients with tuberous sclerosis complex (TSC) is complicated by the multisystemic nature of this condition, age-dependent manifestations, and high clinical variability and by the presence of intellectual disability in at least half of the individuals. In this article, we address the medical needs regarding each TSC-related manifestation in adulthood, and the services and support required. We review existing models of transition in different chronic conditions, discuss our experience in transitioning from the pediatric to the adult TSC Clinic at our Institution, and propose general rules to follow when establishing a transition program for TSC. Although a generalizable transition model for TSC is likely not feasible for all Institutions, a multidisciplinary TSC clinic is probably the best model, developed in accordance with the resources available and country-specific healthcare systems. Coordination of care and education of the adult team should be always sought regardless of the transition model.
