Intensive Care Admission and Early Neuro-Rehabilitation. Lessons for COVID-19?

Coronavirus disease 2019 (COVID-19) requires admission to intensive care (ICU) for the management of acute respiratory distress syndrome in about 5% of cases. Although our understanding of COVID-19 is still incomplete, a growing body of evidence is indicating potential direct deleterious effects on the central and peripheral nervous systems. Indeed, complex and long-lasting physical, cognitive, and functional impairments have often been observed after COVID-19. Early (defined as during and immediately after ICU discharge) rehabilitative interventions are fundamental for reducing the neurological burden of a disease that already heavily affects lung function with pulmonary fibrosis as a possible long-term consequence. In addition, ameliorating neuromuscular weakness with early rehabilitation would improve the efficiency of respiratory function as respiratory muscle atrophy worsens lung capacity. This review briefly summarizes the polymorphic burden of COVID-19 and addresses possible early interventions that could minimize the neurological and systemic impact. In fact, the benefits of early multidisciplinary rehabilitation after an ICU stay have been shown to be advantageous in several clinical conditions making an early rehabilitative approach generalizable and desirable to physicians from a wide range of different specialties.

Real-life evaluation of clinical outcomes in patients undergoing treatment for non-tuberculous mycobacteria lung disease: A ten-year cohort study.

Outcome recognition is a crucial step in the management of non-tuberculous mycobacteria lung disease (NTM-LD). In order to explore NTM-LD outcomes in a real-life setting, an observational, retrospective study enrolling consecutive adults who received treatment for NTM-LD in Milan, Italy, from 2007 to 2017 was conducted. Among 170 patients (68.2% females; median age: 68 years), NTM-LD was mainly due to M. avium complex (MAC) (71.2%), M. kansasii (9.4%) and M. xenopi (7.1%). Along a median follow-up of 31 months, adverse events occurred in 37.6% of the patients. Treatment outcomes of the entire study population included an unsuccessful outcome in 35.3% of the patients, including treatment halted in 13.5%, recurrence in 11.2%, re-infection in 5.3%, treatment failure in 4.1% and relapse in 1.2%. The main reason for treatment halted was drug intolerance. No differences were detected between patients with MAC-LD vs. those with other NTM-LD in terms of unsuccessful outcome in general (35.5% vs. 34.7%). A significantly higher prevalence of patients who underwent treatment halted was found in patients with NTM-LD other than MAC in comparison to patients with MAC-LD (22.4% vs. 9.9%, p = 0.030). One third of adults undergoing treatment for a NTM-LD experiences an unsuccessful outcome with adverse events and treatment discontinuation being major challenges in patients' management.

Survival after pulmonary rehabilitation in patients with COPD: impact of functional exercise capacity and its changes.

The impact of rehabilitation-induced changes in 6-minute walk distance (6MWD) on the survival of patients with chronic obstructive pulmonary disease (COPD) has not been fully elucidated. This study sought to determine the association of baseline 6MWD and its changes after pulmonary rehabilitation (PR) with 5-year survival in patients with COPD. Patients who were referred to a 12-week outpatient PR program were followed up for 5 years postcompletion, and survival status was verified. Survival was analyzed according to four groups based upon initial 6MWD (6MWDi) and its changes (Δ6MWD) after PR (Group 1: 6MWDi ≥350 m and Δ6MWD ≥30 m; Group 2: 6MWDi ≥350 m and Δ6MWD <30 m; Group 3: 6MWDi <350 m and Δ6MWD ≥30 m; and Group 4: 6MWDi <350 m and Δ6MWD <30 m) via Kaplan-Meier analysis and log rank test. Cox regression was performed to identify possible confounders of mortality estimates. In total, 423 patients (with mean ± standard deviation of forced expiratory volume in the first second [FEV1] 43±16% predicted, age 65±8 years, and 6WMDi 381±134 m) underwent PR between 1999 and 2010. Survival rates decreased progressively from Group 1 to Group 4 (Group 1, 81%; Group 2, 69%; Group 3, 47%; Group 4, 27%; log rank test, P<0.05). 6MWDi ≥350 m (hazard ratio [HR] 0.39 [95% confidence interval {CI} 0.30-0.50]) and Δ6MWD ≥30 m (HR 0.66 [95% CI 0.51-0.85]) were strongly and independently associated with survival. Compared with Group 1, mortality risks progressively increased in Group 2 (HR 1.36 [95% CI 0.92-2.00]; not significant), Group 3 (HR 1.90 [95% CI 1.28-2.84]; P=0.001), and Group 4 (HR 3.28 [95% CI 2.02-5.33]; P<0.0001). Both poor 6MWD and lack of improvement >30 m after PR are associated with worse 5-year survival in patients with COPD.
