Background and purpose The European Federation of Neurological Associations (EFNA), in partnership with the NeuroCOVID‐19 taskforce of the European Academy of Neurology (EAN), has investigated the impact of the first wave of the COVID‐19 pandemic on individuals with neurological diseases, as well as the hopes and fears of these patients about the post‐pandemic phase. Methods An EFNA‐EAN survey was available online to any person living with a neurological disorder in Europe. It consisted of 18 items concerning the impact of the first wave of the COVID‐19 pandemic on the medical care of people with neurological disorders, and the hopes and fears of these individuals regarding the post‐pandemic phase. Results For 44.4% of the 443 survey participants, the overall care of their neurological disease during the pandemic was inappropriate. This perception was mainly due to significant delays in accessing medical care (25.7%), insufficiently reliable information received about the potential impact of COVID‐19 on their neurological disease (49.6%), and a substantial lack of involvement in their disease management decisions (54.3%). Participants indicated that their major concerns for the post‐pandemic phase were experiencing longer waiting times to see a specialist (24.1%), suffering from social isolation and deteriorating mental well‐being (23.1%), and facing delays in clinical trials with disinvestment in neuroscience research (13.1%). Conclusions Despite the great efforts of health services to cope with the first wave of the COVID‐19 pandemic, individuals with neurological conditions feel they have been left behind. These findings provide invaluable insights for improving the care of patients with neurological disorders in the further course of the COVID‐19 pandemic., For 44.4% of individuals with neurological disorders participating in the survey, the overall care of their neurological disease during the pandemic was inappropriate due to significant delays in accessing medical care, insufficient information about the potential impact of COVID‐19 on their neurological disease, and a lack of involvement in their disease management decisions. Survey participants indicated that their major concerns for the post‐pandemic phase were experiencing longer waiting times to see a specialist, suffering from social isolation and deteriorating mental well‐being, and facing delays in clinical trials. Overall, despite the great efforts of health services to cope with the first wave of the COVID‐19 pandemic, people with neurological disorders feel they have been left behind.

Background and purpose: The recent SARSCoV2 pandemic has posed multiple challenges to the practice of clinical neurology including recognition of emerging neurological complications and management of coexistent neurological diseases. In a fastevolving pandemic, evidencebased studies are lacking in many areas. This paper presents European Academy of Neurology (EAN) expert consensus statements to guide neurologists caring for patients with COVID19. Methods: A refined Delphi methodology was applied. In round 1, statements were provided by EAN scientific panels (SPs). In round 2, these statements were circulated to SP members not involved in writing them, asking for agreement/disagreement. Items with agreement >70% were retained for round 3, in which SP cochairs rated importance on a fivepoint Likert scale. Results were graded by importance and reported as consensus statements. Results: In round one, 70 statements were provided by 23 SPs. In round two, 259/1061 SP member responses were received. Fiftynine statements obtained >70% agreement and were retained. In round three, responses were received from 55 cochairs of 29 SPs. Whilst general recommendations related to prevention of COVID19 transmission had high levels of agreement and importance, opinion was more varied concerning statements related to therapy. Conclusion: This is the first structured consensus statement on good clinical practice in patients with neurological disease during the COVID19 pandemic that provides immediate guidance for neurologists. In this fastevolving pandemic, a rapid response using refined Delphi methodology is possible, but guidance may be subject to change as further evidence emerges. (VLID)5891876 Version of record

Objective: To develop a novel approach to generate individual maps of white matter (WM) innate immune cell activation using 18F-DPA-714 translocator protein (TSPO) positron emission tomography (PET), and to explore the relationship between these maps and individual trajectories of disability worsening in patients with multiple sclerosis (MS). Methods: Patients with MS (n = 37), whose trajectories of disability worsening over the 2 years preceding study entry were calculated, and healthy controls (n = 19) underwent magnetic resonance magnetic and 18F-DPA-714 PET. A threshold of significant activation of 18F-DPA-714 binding was calculated with a voxel-wise randomized permutation-based comparison between patients and controls, and used to classify each WM voxel in patients as characterized by a significant activation of innate immune cells (DPA+) or not. Individual maps of innate immune cell activation in the WM were employed to calculate the extent of activation in WM regions-of-interests and to classify each WM lesion as "DPA-active", "DPA-inactive" or "unclassified". Results: Compared with the WM of healthy controls, patients with MS had a significantly higher percentage of DPA+ voxels in the normal-appearing WM, (NAWM in patients=24.9±9.7%; WM in controls=14.0±7.8%, p

Sex hormones play a role in pain perception, a key variable in evaluating the progression and treatment of osteoarthritis. The aim of this study was to determine the relationship between salivary concentrations of four steroid hormones and functional/clinical outcomes after hip and knee arthroplasty. Saliva samples were collected from 24 otherwise healthy patients with osteoarthritis before surgery, on admission to rehabilitation, and at hospital discharge. Salivary concentrations of testosterone, 17β-estradiol, dehydroepiandrosterone (DHEA), and cortisol were immunoassayed. Changes in hormone levels were compared with clinical outcomes, as assessed by functional independence measure (FIM®), Barthel Index (BI), and visual analog scale for pain (VAS) scores. Changes in testosterone levels were significantly inversely correlated with VAS (r= -0.53, p=0.043) and FIM® and BI scores in all patients (r= -0.30, p= 0.043, and r= -0.35, p=0.031, respectively). The testosterone to cortisol ratio was inversely correlated with BI scores in all patients (r= -0.30, p=0.040), and in the men (r= -0.55, p=0.005) and the women (r= -0.28, p=0.042) when analyzed separately. Changes in salivary testosterone concentrations closely correlated with clinical outcome measurements for total hip and knee arthroplasty. Clinical outcome after arthroplasty was generally better among the men.

We investigated sub-clinical cardiovascular involvement in primary Sjögren's syndrome (pSS) patients by means of ADMA, coronary flow reserve (CFR), intima media thickness (cIMT), pulse wave velocity (PWV) and myocardial deformation.The study involved 22 outpatients with pSS (6 males, 16 females; mean age 60.14±7.81 years) and no documentable cardiovascular disease, and 22 age- and gender-matched controls. Dipyridamole transthoracic stress echocardiography was used to evaluate wall motion and CFR. A CFR value of2.5 was considered a sign of impaired coronary function. We also evaluated cIMT arterial stiffness PWV and plasma ADMA levels, and made a speckle tracking echocardiography (STE) analysis.All of the patients were affected by pSS. Although within the normal range, the patients' CFR was lower than that of the controls (median 2.70; IQR 2.40-2.90 vs. 3.20; IQR 3.06-3.33; p0.0001), whereas their ADMA levels were significantly higher (median 0.81 μM; IQR 0.79-0.85 μM vs. 0.54 μM; IQR 0.52-0.58 μM; p0.0001). Both left and right PWV values were significantly higher in the patients than in the controls (median 8.8 m/s right and 8.9 m/s left vs. 6.86 and 6.89 m/s), whereas QIMT was substantially similar in the two groups.Higher ADMA levels suggest the presence of endothelial dysfunction and sub-clinical atherosclerosis in pSS patients, even in the case of a normal CFR. This finding is supported by the PWV values, which were higher in the pSS patients. ADMA levels and PWV values may be useful markers for identifying early endothelial dysfunction in pSS patients.

BACKGROUND AND PURPOSE The recent SARS-CoV-2 pandemic has posed multiple challenges to the practice of clinical neurology including recognition of emerging neurological complications and management of coexistent neurological diseases. In a fast-evolving pandemic, evidence-based studies are lacking in many areas.

Background Sarcopenia gained importance in the evaluation of patients with chronic respiratory diseases, including idiopathic pulmonary fibrosis (IPF), since it may impact negatively on clinical outcomes. Aim Aim of this study is to evaluate the prevalence and factors associated with sarcopenia, defined according to the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) 2019 definition, and to evaluate the prevalence of the single criteria that define the EWGSOP2 definition (muscle strength, muscle quantity and physical performance), in a cohort of consecutive patients with IPF prospectively followed up in 9 hospitals in Northern Italy between December 2018 and May 2021. Methods Enrolled patients underwent an extensive pulmonary and nutritional assessment, including bioelectrical impedance analysis, dynamometry and 4-m gait speed test, both at IPF diagnosis and at 6-month follow-up. Results Out of the 83 patients (81% males, mean age 72.5 years) with IPF at disease diagnosis enrolled in the study, 19 (22.9%) showed sarcopenia, including 2 (2.4%) with severe sarcopenia, 5 (6.0%) with confirmed sarcopenia and 12 (14.5%) with probable sarcopenia. Sarcopenia was associated with a significantly higher severity of the disease and sedentary lifestyle, while no differences were observed in regards to body mass index, history of weight loss and comorbidities between patients with and without sarcopenia. Out of the 64 patients without sarcopenia at baseline, 16 cases showed alteration of muscle quantity and/or physical performance. In the 51 patients with complete data at 6-month follow-up, there were no cases of severe sarcopenia, 1 case (2.0%) showed confirmed sarcopenia, while the prevalence of probable sarcopenia was 19.6% (10 cases). No differences in regards to antifibrotic treatment received and onset of gastrointestinal side effects were observed between patients with and without sarcopenia at follow-up. Conclusions The prevalence of sarcopenia in patients with IPF both at diagnosis and at 6-month follow-up was low but not negligible and was associated with higher severity of the disease and sedentary lifestyle. In IPF patients, a comprehensive diagnostic work-up including all the criteria defining the EWGSOP2 definition might be more useful than a series testing for prompt recognition of nutritional and physical performance abnormalities.

Background Long-term pulmonary sequelae following hospitalization for SARS-CoV-2 pneumonia is largely unclear. The aim of this study was to identify and characterise pulmonary sequelae caused by SARS-CoV-2 pneumonia at 12-month from discharge. Methods In this multicentre, prospective, observational study, patients hospitalised for SARS-CoV-2 pneumonia and without prior diagnosis of structural lung diseases were stratified by maximum ventilatory support (“oxygen only”, “continuous positive airway pressure (CPAP)” and “invasive mechanical ventilation (IMV)”) and followed up at 12 months from discharge. Pulmonary function tests and diffusion capacity for carbon monoxide (DLCO), 6 min walking test, high resolution CT (HRCT) scan, and modified Medical Research Council (mMRC) dyspnea scale were collected. Results Out of 287 patients hospitalized with SARS-CoV-2 pneumonia and followed up at 1 year, DLCO impairment, mainly of mild entity and improved with respect to the 6-month follow-up, was observed more frequently in the “oxygen only” and “IMV” group (53% and 49% of patients, respectively), compared to 29% in the “CPAP” group. Abnormalities at chest HRCT were found in 46%, 65% and 80% of cases in the “oxygen only”, “CPAP” and “IMV” group, respectively. Non-fibrotic interstitial lung abnormalities, in particular reticulations and ground-glass attenuation, were the main finding, while honeycombing was found only in 1% of cases. Older patients and those requiring IMV were at higher risk of developing radiological pulmonary sequelae. Dyspnea evaluated through mMRC scale was reported by 35% of patients with no differences between groups, compared to 29% at 6-month follow-up. Conclusion DLCO alteration and non-fibrotic interstitial lung abnormalities are common after 1 year from hospitalization due to SARS-CoV-2 pneumonia, particularly in older patients requiring higher ventilatory support. Studies with longer follow-ups are needed.

BackgroundNutritional status impacts quality of life and prognosis of patients with respiratory diseases, including idiopathic pulmonary fibrosis (IPF). However, there is a lack of studies performing an extensive nutritional assessment of IPF patients. This study aimed to investigate the nutritional status and to identify nutritional phenotypes in a cohort of IPF patients at diagnosis.MethodsPatients underwent a thorough pulmonary and nutritional evaluation including questionnaires on nutritional status, and physical activity, anthropometry, body impedance, dynamometry, 4-m gait speed and blood tests.Results90 IPF patients (78.9% males, mean age 72.7 years) were enrolled. The majority of patients were classified as Gender-Age-Physiology Index stage 2 (47, 52.2%) with an inactive lifestyle according to International Physical Activity Questionnaire score (39, 43.3%), and had mean forced vital capacity and diffusing capacity for carbon monoxide 86.5% and 54.2%, respectively. In regards to nutritional phenotypes, the majority of patients were normally nourished (67.8%, 95% CI 58.6–77.7%), followed by non-sarcopenic obese (25.3%, 95% CI 16.1–35.2%), sarcopenic (4.6%, 95% CI 0.0–14.5%) and sarcopenic obese (2.3%, 95% CI 0.0–12.2%). Among the normally nourished, 49.2% showed early signs of nutritional and physical performance alterations, including body mass index ≥30 kg·m−2 in 4.3%, history of weight loss ≥5% in 11.9%, and reduction of gait speed and hand grip strength in 11.9% and 35.6%, respectively. Low vitamin D values were observed in 56.3% of cases.ConclusionsIPF patients at diagnosis are mainly normally nourished and obese, but early signs of nutritional and physical performance impairment can already be identified at this stage.

Nontuberculous mycobacterial (NTM) pulmonary disease (PD) is an emerging condition with heterogeneous manifestations from both the microbiological and the clinical point of view. Diagnostic and therapeutic guidelines are available but there are still unmet patients' and physicians' needs, including therapy-related adverse events, symptom control, management of comorbidities, risk of re-exposure to the pathogen and unfavourable outcomes. In the present review, we provide currently available evidence for an integrated approach to NTM-PD beyond antibiotic therapy. This includes 1) avoiding exposure to environments where mycobacteria are present and careful evaluation of lifestyle and habits; 2) implementing a personalised pulmonary rehabilitation plan and airway clearance techniques to improve symptoms, exercise capacity, health-related quality of life (QoL) and functional capacity in daily living activities; 3) a nutritional evaluation and intervention to improve health-related QoL and to control gastrointestinal side-effects during antimicrobial therapy, particularly in those with low body mass index and history of weight loss; and 4) managing comorbidities that affect disease outcomes, including structural lung diseases, immune status evaluation and psychological support when appropriate., An integrated approach, including risk factor prevention, management of comorbidities, nutritional evaluation and intervention and pulmonary rehabilitation, should be considered in the optimal management of nontuberculous mycobacterial pulmonary disease https://bit.ly/2YEqvQg

Background: Long-term pulmonary sequelae following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia are not yet confirmed; however, preliminary observations suggest a possible relevant clinical, functional, and radiological impairment. Objectives: The aim of this study was to identify and characterize pulmonary sequelae caused by SARS-CoV-2 pneumonia at 6-month follow-up. Methods: In this multicentre, prospective, observational cohort study, patients hospitalized for SARS-CoV-2 pneumonia and without prior diagnosis of structural lung diseases were stratified by maximum ventilatory support (“oxygen only,” “continuous positive airway pressure,” and “invasive mechanical ventilation”) and followed up at 6 months from discharge. Pulmonary function tests and diffusion capacity for carbon monoxide (DLCO), 6-min walking test, chest X-ray, physical examination, and modified Medical Research Council (mMRC) dyspnoea score were collected. Results: Between March and June 2020, 312 patients were enrolled (83, 27% women; median interquartile range age 61.1 [53.4, 69.3] years). The parameters that showed the highest rate of impairment were DLCO and chest X-ray, in 46% and 25% of patients, respectively. However, only a minority of patients reported dyspnoea (31%), defined as mMRC ≥1, or showed restrictive ventilatory defects (9%). In the logistic regression model, having asthma as a comorbidity was associated with DLCO impairment at follow-up, while prophylactic heparin administration during hospitalization appeared as a protective factor. The need for invasive ventilatory support during hospitalization was associated with chest imaging abnormalities. Conclusions: DLCO and radiological assessment appear to be the most sensitive tools to monitor patients with the coronavirus disease 2019 (COVID-19) during follow-up. Future studies with longer follow-up are warranted to better understand pulmonary sequelae.

Our objective was to develop a novel approach to generate individual maps of white matter (WM) innate immune cell activation using (18)F-DPA-714 translocator protein PET and to explore the relationship between these maps and individual trajectories of worsening disability in patients with multiple sclerosis (MS). Methods: Patients with MS (n = 37), whose trajectories of worsening disability over the 2 y preceding study entry were calculated, and healthy controls (n = 19) underwent MRI and (18)F-DPA-714 PET. A threshold for significant activation of (18)F-DPA-714 binding was calculated with a voxelwise randomized permutation-based comparison between patients and controls and used to classify each WM voxel in all subjects as characterized by a significant activation of innate immune cells (DPA+) or not. Individual maps of innate immune cell activation in the WM were used to calculate the extent of activation in WM regions of interests and to classify each WM lesion as DPA-active, DPA-inactive, or unclassified. Results: Compared with the WM of healthy controls, patients with MS had a significantly higher percentage of DPA+ voxels in the normal-appearing WM (NAWM) (NAWM in patients, 24.6% ± 1.4%; WM in controls, 14.6% ± 2.0%; P < 0.001). In patients with MS, the percentage of DPA+ voxels increased significantly from the NAWM to the perilesional areas, T2 hyperintense lesions, and T1 hypointense lesions (38.1% ± 2.6%, 45.0% ± 2.6%, 51.8% ± 2.6%, respectively; P < 0.001). Among the 1,379 T2 lesions identified, 512 were defined as DPA-active and 258 as DPA-inactive. A higher number of lesions classified as DPA-active (odds ratio, 1.13; P = 0.009), a higher percentage of DPA+ voxels in the NAWM (odds ratio, 1.16; P = 0.009), and a higher percentage of DPA+ voxels in T1 spin-echo lesions (odds ratio, 1.06; P = 0.036) were significantly associated with a retrospectively more severe clinical trajectory in patients with MS. Conclusion: A more severe trajectory of disability worsening in MS is associated with innate immune cell activation inside and around WM lesions. (18)F-DPA-714 PET may provide a promising biomarker to identify patients at risk of a severe clinical trajectory.

Interstitial lung diseases (ILDs) may be complicated by chronic respiratory failure (CRF), especially in the advanced stages. Aim of this narrative review is to evaluate the current evidence in management of CRF in ILDs. Many physiological mechanisms underlie CRF in ILDs, including lung restriction, ventilation/perfusion mismatch, impaired diffusion capacity and pulmonary vascular damage. Intermittent exertional hypoxemia is often the initial sign of CRF, evolving, as ILD progresses, into continuous hypoxemia. In the majority of the cases, the development of CRF is secondary to the worsening of the underlying disease; however, associated comorbidities may also play a role. When managing CRF in ILDs, the need for pulmonary rehabilitation, the referral to lung transplant centers and palliative care should be assessed and, if necessary, promptly offered. Long-term oxygen therapy is commonly prescribed in case of resting or exertional hypoxemia with the purpose to decrease dyspnea and improve exercise tolerance. High-Flow Nasal Cannula oxygen therapy may be used as an alternative to conventional oxygen therapy for ILD patients with severe hypoxemia requiring both high flows and high oxygen concentrations. Non-Invasive Ventilation may be used in the chronic setting for palliation of end-stage ILD patients, although the evidence to support this application is very limited.

BacKGrOUNd: The correct timing for bronchoscopy in massive hemoptysis is well established, whereas in mild-to-moderate hemoptysis there still is uncertainty. The aim of our study was to evaluate if performing a fibrobronchoscopy (FBS) within 48 hours after the onset of mild-to-moderate hemoptysis was related to a higher possibility to identify the site and the cause of bleeding, compared to a delayed one. meTHOdS: We conducted a retrospective study over one-year period from march 2015, in which consecutive patients admitted to the emergency department underwent FBS for spontaneous mild-to-moderate hemoptysis in our medium-size teaching hospital. RESULTS: We included 69 patients. Definitive diagnosis was achieved in 52 cases (75%) combining clinical, imaging and endoscopic data (neoplastic diseases 22%, infections 20%, alveolar hemorrhage 13%). FBS was performed within 48 hours of symptoms onset in 41 patients (59%). The site of bleeding was identified in 28 cases (41%), 64% of which underwent FBS within 48 hours. Endoscopic diagnosis was reached in 45 patients (65%), 60% of which underwent FBS within 48 hours. No statistical association with localization (P=0.62) or diagnosis (P=1.00) was found with early FBS. Despite a high prevalence in our cohort of patients treated with anticoagulant or antiplatelet drugs (39%), we found no statistical association with bronchoscopy localization (P=0.12) and diagnosis (P=0.21). cONcLUSiONS: in conclusion, in case of mild to moderate hemoptysis, an early bronchoscopy in the emergency department setting does not seem to improve the possibility to find neither the cause nor the localization of the bleeding source.

Background Interstitial lung diseases (ILDs) are a heterogeneous group of diseases characterized by widespread fibrotic and inflammatory abnormalities of the lung. Respiratory failure is a common complication in advanced stages or following acute worsening of the underlying disease. Aim of this review is to evaluate the current evidence in determining the best management of acute respiratory failure (ARF) in ILDs. Methods A literature search was performed in the Medline/PubMed and EMBASE databases to identify studies that investigated the management of ARF in ILDs (the last search was conducted on November 2017). Results In managing ARF, it is important to establish an adequate diagnostic and therapeutic management depending on whether the patient has an underlying known chronic ILD or ARF is presenting in an unknown or de novo ILD. In the first case both primary causes, such as acute exacerbations of the disease, and secondary causes, including concomitant pulmonary infections, fluid overload and pulmonary embolism need to be investigated. In the second case, a diagnostic work-up that includes investigations in regards to ILD etiology, such as autoimmune screening and bronchoalveolar lavage, should be performed, and possible concomitant causes of ARF have to be ruled out. Oxygen supplementation and ventilatory support need to be titrated according to the severity of ARF and patients’ therapeutic options. High-Flow Nasal oxygen might potentially be an alternative to conventional oxygen therapy in patients requiring both high flows and high oxygen concentrations to correct hypoxemia and control dyspnea, however the evidence is still scarce. Neither Non-Invasive Ventilation (NIV) nor Invasive Mechanical Ventilation (IMV) seem to change the poor outcomes associated to advanced stages of ILDs. However, in selected patients, such as those with less severe ARF, a NIV trial might help in the early recognition of NIV-responder patients, who may present a better short-term prognosis. More invasive techniques, including IMV and Extracorporeal Membrane Oxygenation, should be limited to patients listed for lung transplant or with reversible causes of ARF. Conclusions Despite the overall poor prognosis of ARF in ILDs, a personalized approach may positively influence patients’ management, possibly leading to improved outcomes. However, further studies are warranted.
