Multicenter Study Comparative Study
Prevalence, Treatment and Outcomes Associated with Obstructive Sleep Apnea Among Patients Hospitalized with Pneumonia.
OSA is associated with increased risks of respiratory complications following surgery. However, its relationship to the outcomes of hospitalized medical patients is unknown. ⋯ Among patients hospitalized for pneumonia, OSA is associated with higher initial rates of mechanical ventilation, increased risk of clinical deterioration, and higher resource use, yet a modestly lower risk of inpatient mortality.

The respiratory tract of human subjects is constantly exposed to harmful microbes and air pollutants. The immune system responds to these offenders to protect the host, but an unbalanced inflammatory response itself may promote tissue damage and ultimately lead to acute and chronic respiratory diseases. ⋯ Assembly of these intracellular danger sensors in cells of the respiratory mucosa and alveolar compartment triggers a proinflammatory cell death mode termed pyroptosis and leads to secretion of bioactive IL-1β and IL-18. Here, we summarize and review the inflammasome and its downstream effectors as therapeutic targets for the treatment of respiratory diseases.

There is increasing interest in the use of telemedicine to assist in the management of chronic diseases. Telemedicine possibilities for patients with COPD include medical consultations, in-home patient monitoring, and remote rehabilitation. Teleconsultations have been used successfully, saving time and travel costs for patients with only a few subsequently requiring face-to-face visits. ⋯ Given the health-care costs and commitment involved in telemonitoring, well-designed longer-term multicenter studies with appropriate follow-up are required prior to its more widespread application. Emerging evidence from preliminary trials of telerehabilitation for the pulmonary patient is encouraging. It may represent a useful tool for increasing access and building capacity, especially in remote areas.

Guidelines recommend mediastinal lymph node sampling as the fi rst invasive diagnostic procedure in patients with suspected lung cancer with mediastinal lymphadenopathy without distant metastases. ⋯ Guideline-consistent care varied regionally and was associated with physician-level factors, suggesting that a lack of effective physician training may be contributing to the quality gaps observed.

Dysphagia and aspiration pneumonia are two causes of morbidity in Parkinson disease (PD). In PD, impaired airway clearance can lead to penetration of foreign material, resulting in a high prevalence of aspiration pneumonia and death. This study examines three different devices for measurement of peak airflow during voluntary cough in healthy control subjects and those with PD. Two simple and low-cost devices for measuring peak cough airflow were compared with the "gold standard" pneumotachograph. ⋯ The analog and digital peak airflow meters are suitable alternatives to the gold standard pneumotachograph due to their low cost, portability, ease of use, and high sensitivity relative to normative peak cough airflows. Voluntary cough airflow measures may serve as a noninvasive means of screening for aspiration risk in target populations. Additionally, quantification of cough strength through use of predetermined limens for weak, moderate, and strong cough may assist clinicians in better describing and tracking cough strength as a contributing factor to aspiration risk.
