Randomized Controlled Trial
Cerebral oxygenation in patients with obstructive sleep apnea. Effects of hypoxia at altitude and of acetazolamide.
Sleep-disordered breathing may impair cerebral oxygenation in patients with OSA syndrome, in particular during altitude travel. We studied cerebral tissue oxygenation (CTO) at low and moderate altitude in patients with OSA and evaluated whether acetazolamide improved CTO. ⋯ In patients with OSA staying at altitude, nocturnal cerebral and arterial oxygenation were reduced in association with exacerbated sleep apnea. Acetazolamide partially improved CTO, Spo2, and sleep apnea without impairing the cerebral blood flow response to apneas.

Multicenter Study
Inappropriate care in European Intensive Care Units: confronting views from nurses, junior and senior physicians.
ICU care providers often feel that the care given to a patient may be inconsistent with their professional knowledge or beliefs. This study aimed to assess differences in, and reasons for, perceived inappropriate care (PIC) across ICU care providers with varying levels of decision-making power. ⋯ ICU care providers agree that excessive care is a true issue in the ICU. However, they differ in the reasons for the PIC, reflecting the roles each caregiver has in the ICU. Nurses charge physicians with a lack of initiative and poor communication, whereas physicians more often ascribe prognostic uncertainty. Teaching ICU physicians to deal with prognostic uncertainty in more adequate ways and to promote ethical discussions in their teams may be pivotal to improving moral distress and the quality of patient care.

Randomized Controlled Trial
Endosonographic Mediastinal Lymph Node Staging of Lung Cancer.
It is unclear whether endoscopic mediastinal lymph node (LN) staging techniques are equivalent to surgical mediastinal staging (SMS) techniques in patients with potentially operable non-small cell lung cancer (NSCLC). ⋯ The combined EBUS/EUS procedure can replace surgical mediastinal staging in patients with potentially resectable NSCLC. Additionally, endosonography leads to improved staging compared with SMS because it allows the biopsy of LNs and metastases unattainable with SMS techniques.

The Quality of Life Questionnaire-Bronchiectasis (QOL-B) is the first disease-specific, patient-reported outcome measure for patients with bronchiectasis. Content validity, cognitive testing, responsivity to open-label treatment, and psychometric analyses are presented. ⋯ This interim QOL-B is a promising tool for evaluating the efficacy of new therapies for patients with bronchiectasis and for measuring symptoms, functioning, and quality of life in these patients on a routine basis. A final psychometric validation study is needed and is forthcoming.

Interstitial lung disease (ILD) is the leading cause of morbidity and mortality in patients with systemic sclerosis (SSc); however, prognostication of SSc-associated ILD (SSc-ILD) remains challenging. We conducted a systematic review to identify variables that predict mortality and ILD progression in SSc-ILD. ⋯ Mortality and ILD progression were predicted by several patient-specific, ILD-specific, and SSc-specific factors. Additional prospective studies are required to validate these preliminary findings and to identify combinations of variables that accurately predict the prognosis of SSc-ILD.
