The use of antipsychotic agents has been associated with increased pneumonia risk, but although people with dementia are particularly susceptible to pneumonia, only one small study has assessed the risk of pneumonia in relation to the use of antipsychotic agents among people with Alzheimer disease (AD). ⋯ Regardless of applied study design, treatment duration, or the choice of drug, the use of antipsychotic agents was associated with a higher risk of pneumonia. With observational data, we cannot fully rule out a shared causality between pneumonia and the use of antipsychotic agents, but the risk to benefit balance should be considered when antipsychotic agents are prescribed.

Although 28% to 49% of severe sepsis hospitalizations have been described as being "culture negative," there are very limited data on the epidemiology and outcomes of those with culture-negative severe sepsis (CNSS). The objectives of this study were to investigate the proportion and trends of CNSS and its association with mortality. ⋯ CNSS among hospitalized patients is common, and its proportion is on the rise. CNSS is associated with greater acute organ dysfunction and mortality. Having CNSS is an independent predictor of death.

A woman in her 60s with a history of hepatitis C with cirrhosis and major depressive disorder with psychotic features was admitted to the inpatient psychiatric unit for suicidal ideation. She was initially treated with a combination of sertraline and paliperidone. The paliperidone was subsequently changed to risperidone and ultimately to olanzapine. ⋯ Over 2 days, her mental status continued to worsen and she developed fever and tachycardia. She was transferred to the ICU and endotracheally intubated for inability to protect her airway. She was started on lactulose via orogastric tube but showed no improvement in her mental status after 2 days despite having two or three bowel movements per day.

Lung clearance index (LCI) has good clinimetric properties and an acceptable feasibility profile as a surrogate end point in cystic fibrosis (CF). Although most studies to date have been in children, increasing numbers of adults with CF also have normal spirometric findings. Further study of LCI as an end point in adults with CF is required. Therefore, the purpose of this study was to determine the clinimetric properties of LCI across the age range of people with CF. ⋯ These data support the use of LCI as a surrogate outcome measure in CF clinical trials in adults as well as in children.

CPAP is the gold standard treatment for OSA and was conceived to be applied through a nasal interface. This study was designed to determine the acute effects of changing the nasal CPAP route to oronasal and oral in upper airway patency during sleep in patients with OSA. We hypothesized that the oronasal route may compromise CPAP's effectiveness in treating OSA. ⋯ CPAP delivered through the oronasal route may compromise CPAP's effectiveness in treating OSA.
