Sedation in intensive care is fundamental for optimizing clinical outcomes. For many years the world has been facing high rates of opioid use, and to combat the increasing opioid addiction plans at both national and international level have been implemented.1 The COVID-19 pandemic posed a major challenge for health systems and also increased the use of sedatives and opioid analgesia for prolonged periods of time, and at high doses, in a significant proportion of patients. In our institutions, the shortage of many drugs for intravenous (IV) analgosedation forces us to alternatives to replace out-of-stock drugs or to seek sedation goals, which are difficult to obtain with traditional drugs at high doses.2 METHODS: This was an analytical retrospective cohort study evaluating the follow-up of subjects with inclusion criteria from ICU admission to discharge (alive or dead). Five end points were measured: need for high-dose opioids (≥ 200 µg/h), comparison of inhaled versus IV sedation of opioid analgesic doses, midazolam dose, need for muscle relaxant, and risk of delirium. ⋯ Inhaled sedation was associated with lower doses of opioids, benzodiazepines, and muscle relaxants compared to IV sedation. This therapy should be considered as an alternative in critically ill patients requiring prolonged ventilatory support and where IV sedation is not possible, always under adequate supervision of ICU staff.

Randomized Controlled Trial
The Effect of Adding Noninvasive Ventilation to High-Intensity Exercise on Peripheral and Respiratory Muscle Oxygenation.
We sought to assess whether noninvasive ventilation (NIV) as an adjunct with high-intensity exercise (HIEx) is more effective than exercise alone or exercise + sham on respiratory and peripheral oxygenation and vascular function in subjects with coexisting COPD and heart failure (HF). ⋯ NIV as an adjunct to HIEx can acutely unload the respiratory musculature with better redistribution of available blood flow and beneficially modulate endothelial function. These results may influence the approach to cardiopulmonary rehabilitation in patients with coexisting COPD-HF.

Observational Study
Oxygen Desaturation and Persistence of Symptoms during Activities of Daily Living in Patients following Hospital Discharge for COVID-19.
COVID-19 can cause respiratory and multisystemic impairments, which lead to impaired activities of daily living (ADL). Telemonitoring after discharge from the hospital may help identify the persistence of such limitations during ADLs simulations. The aim of this study was to compare SpO2 , fatigue, and dyspnea through telemonitoring during a battery of 4 ADLs in patients following hospital discharge for COVID-19. ⋯ SpO2 was similar among the ADLs but walking triggered desaturation in a larger number of subjects. The subjects presented with mild-to-intense fatigue and dyspnea during ADLs 30 d after discharge after hospitalization for COVID-19 regardless of desaturation status, which demonstrated that the persistence of symptoms is independent of hypoxemia during exercise.

Observational Study
Concise Versus Extended Lung Ultrasound Score to Monitor Critically Ill Patients With COVID-19.
Lung ultrasound (LUS) can be used to monitor critically ill patients with COVID-19, but the optimal number of examined lung zones is disputed. ⋯ Concise LUS was equally informative as extended LUS for monitoring critically ill subjects with COVID-19 in supine or prone position. Clinicians can monitor patients undergoing position changes but must be wary that LUS score index alterations may result from the position change itself rather than disease progression or clinical improvement.

COPD is characterized by progressive and irreversible air flow limitations. Single-inhaler therapies (SITTs) incorporating an inhaled corticosteroid, a long-acting muscarinic antagonist, and a long-acting β2-agonist have been shown to effectively alleviate symptoms and improve lung function. Fluticasone-furoate/umeclidinium/vilanterol (F/U/V) and budesonide/glycopyrronium/formoterol (B/G/F) are available as SITT in Japan. However, the clinical differences between these 2 combinations and the predictors of their proper use have not been established. This study aimed to identify the subject characteristics that could predict the effectiveness of inhaler therapy. ⋯ Our results showed that SITT significantly improved the IC, %IC, FVC, and %FEV1 when compared to pre-intervention and that F/U/V was more effective in subjects with severe symptoms, whereas B/G/F was more effective in subjects with mild symptoms.
