A prospective study was performed to confirm the prevalence pattern of the most frequent co-morbidities and to evaluate whether characteristics of patients, specific comorbidities and increasing number of comorbidities are independently associated with poorer outcomes in a population with complex chronic obstructive pulmonary disease (COPD) submitted for pulmonary rehabilitation (PR).316 outpatients (mean¡SD age 68¡7 yrs) were studied. The outcomes recorded were comorbidities and proportion of patients with a pre-defined minimally significant change in exercise tolerance (6-min walk distance (6MWD) +54 m), breathlessness (Medical Research Council (MRC) score -1 point) and quality of life (St George's Respiratory Questionnaire -4 points).62% of patients reported comorbidities; systemic hypertension (35%), dyslipidaemia (13%), diabetes (12%) and coronary disease (11%) were the most frequent. Of these patients, .45% improved over the minimum clinically important difference in all the outcomes. In a logistic regression model, baseline 6MWD (OR 0.99, 95% CI 0.98-0.99; p50.001), MRC score (OR 12.88, 95% CI 6.89-24.00; p50.001) and arterial carbon dioxide tension (OR 1.08, 95% CI 1.00-1.15; p50.034) correlated with the proportion of patients who improved 6MWD and MRC, respectively. Presence of osteoporosis reduced the success rate in 6MWD (OR 0.28, 95% CI 0.11-0.70; p50.006).A substantial prevalence of comorbidities in COPD outpatients referred for PR was confirmed. Only the individual's disability and the presence of osteoporosis were independently associated with poorer rehabilitation outcomes.

The rapid evolution of the health emergency linked to the spread of severe acute respiratory syndrome coronavirus 2 requires specifications for the rehabilitative management of patients with coronavirus disease 2019 . The symptomatic evolution of patients with COVID-19 is characterized by 2 phases: an acute phase in which respiratory symptoms prevail and a postacute phase in which patients can show symptoms related to prolonged immobilization, to previous and current respiratory dysfunctions, and to cognitive and emotional disorders. Thus, there is the need for specialized rehabilitative care for these patients. This communication reports the experience of the San Raffaele Hospital of Milan and recommends the setup of specialized clinical pathways for the rehabilitation of patients with COVID-19. In this hospital, between February 1 and March 2, 2020, about 50 patients were admitted every day with COVID-19 symptoms. In those days, about 400 acute care beds were created (intensive care/infectious diseases). In the following 30 days, from March 2 to mid-April, despite the presence of 60 daily arrivals to the emergency department, the organization of patient flow between different wards was modified, and several different units were created based on a more accurate integration of patients' needs. According to this new organization, patients were admitted first to acute care COVID-19 units and then to COVID-19 rehabilitation units, post-COVID-19 rehabilitation units, and/or quarantine/observation units. After hospital discharge, telemedicine was used to follow-up with patients at home. Such clinical pathways should each involve dedicated multidisciplinary teams composed of pulmonologists, physiatrists, neurologists, cardiologists, physiotherapists, neuropsychologists, occupational therapists, speech therapists, and nutritionists.

Coughing is an important defensive reflex that occurs through the stimulation of a complex reflex arc. It accounts for a significant number of consultations both at the level of general practitioner and of respiratory specialists. In this review we first analyze the cough reflex under normal conditions; then we analyze the anatomy and the neuro-pathophysiology of the cough reflex arc. The aim of this review is to provide the anatomic and pathophysiologic elements of evaluation of the complex and multiple etiologies of cough.

A relatively high prevalence of malnutrition and sarcopenia was found in COPD patients applying international standard criteria, with some discrepancy between the two diagnoses. In addition, clear-cut changes in raw BIA variables were observed in malnourished patients with systemic inflammation and sarcopenic patients.

Omalizumab was the first, and for a long time the only available monoclonal antibody for the add-on treatment of severe allergic asthma. In particular, omalizumab selectively targets human immunoglobulin (Ig)E, forming small-size immune complexes that inhibit IgE binding to its high- and low-affinity receptors. Therefore, omalizumab effectively blunts the immune response in atopic asthmatic patients, thus significantly improving the control of asthma symptoms and successfully preventing disease exacerbations. These very positive effects of omalizumab make it possible to drastically decrease both referrals to the emergency room and hospitalizations for asthma exacerbations. Such important therapeutic actions of omalizumab have been documented by several randomized clinical trials, and especially by more than 10 years of real-life experience in daily clinical practice. Omalizumab can also interfere with airway remodelling by inhibiting the activation of IgE receptors located on structural cells such as bronchial epithelial cells and airway smooth muscle cells. Moreover, omalizumab is characterized by a very good safety and tolerability profile. Hence, omalizumab represents a valuable therapeutic option for the add-on biological treatment of severe allergic asthma.
