Little is known about folate and atopy or severe asthma exacerbations. We examined whether folate deficiency is associated with number of positive skin tests to allergens or severe asthma exacerbations in a high-risk population and further assessed whether such association is explained or modified by vitamin D status. ⋯ Folate deficiency is associated with increased degree of atopy and severe asthma exacerbations in school-aged Puerto Ricans. Vitamin D insufficiency may further increase detrimental effects of folate deficiency on severe asthma exacerbations.

There is a paucity of evidence regarding the role of tunneled pleural catheters in pleural effusions caused by congestive heart failure that is refractory to medical management. ⋯ This single-center, retrospective study demonstrated the feasibility of catheter placement used alone or with talc poudrage for the treatment of refractory pleural effusions associated with congestive heart failure. The addition of talc poudrage might increase the pleurodesis rate and reduce the days to catheter removal in highly selected patients. Prospective studies on a larger number of patients are warranted to verify the safety and efficacy of this intervention.

Recent research suggests that the asthma epidemic observed in the 1980s and 1990s has stabilized. Changing trends in asthma may have an impact on the well-reported global phenomenon of the "asthma September peak." The 38th week of the year has been identified as the peak time for asthma exacerbations among children. ⋯ While the magnitude of the September peak has decreased over time, the asthma ED visit rate remains significantly higher in September than in other months. Physician visits are also highest in the fall. These findings stress the importance of empowering children and families to maintain good asthma control throughout the year, including hand washing, to minimize respiratory viral infections in September.

Early mobilization of patients in the intensive care unit (ICU) is safe, feasible, and beneficial. However, implementation of early mobility as part of routine clinical care can be challenging. The objective of this review is to identify barriers to early mobilization and discuss strategies to overcome such barriers. ⋯ These barriers were variable across ICUs and within disciplines, depending on the ICU patient population, setting, attitude, and ICU culture. To overcome the identified barriers, >70 strategies were reported and are synthesized herein, including: implementation of safety guidelines; use of mobility protocols; interprofessional training, education, and rounds; and involvement of physician champions. Systematic efforts to change ICU culture to prioritize early mobilization using an interprofessional approach and multiple targeted strategies are important components of successfully implementing early mobility in clinical practice.

Observational Study
Outcomes of Patients with Alcohol Withdrawal Syndrome Treated with High-Dose Sedatives and Deferred Intubation.
High doses of sedating drugs are often used to manage critically ill patients with alcohol withdrawal syndrome. ⋯ In this single-center, observational study, where endotracheal intubation was deferred until aspiration or cardiopulmonary decompensation, treatment of alcohol withdrawal syndrome with high-dose, continuously infused sedating medications was not associated with excess morbidity or mortality.
