Comparative Study Observational Study
The Risk of Latent Tuberculosis Infection in Respiratory Therapists in a Country with Intermediate Incidence.
Respiratory therapists (RTs) are exposed to aerosols more frequently than other health care workers (HCWs) and might bear a higher risk for tuberculosis (TB) infection. The QuantiFERON-TB Gold (QFTG) test was used to evaluate the risk for TB infection in Taiwan, a country with intermediate TB incidence. ⋯ RTs had no higher risk for latent TB infection than other HCWs in a country with intermediate TB incidence.

Comparative Study
Ventilation Efficiency and Respiratory Muscle Function at Different Levels of CPAP in Intubated Prematurely Born Infants.
CPAP improves respiratory function in prematurely born infants by establishing and maintaining functional residual capacity, but the level of CPAP that optimizes respiratory function has not been adequately described. We compared ventilation efficiency and respiratory muscle function at different levels of CPAP. ⋯ Increasing the level of CPAP from 4 to 6 cm H2O was associated with enhanced ventilation efficiency and respiratory muscle function in convalescent premature infants on ventilation, but there was no further benefit from increasing the pressure >6 cm H2O.

Home oxygen therapy is commonly prescribed for patients who remain hypoxemic at hospital discharge, although evidence supporting this practice is lacking. This study aimed to evaluate oxygen prescription and follow-up for patients who were prescribed post-discharge short-term oxygen therapy (STOT) and to assess their long-term outcome. ⋯ A significant proportion of subjects who were prescribed post-discharge STOT did not fulfill the recommended prescribing criteria. The long-term prognosis for subjects who were prescribed post-discharge STOT was poor.

In a previous study of subjects suspected of having ventilator-associated pneumonia, a rapid susceptibility testing approach by using ETEST (BioMérieux) strips directly applied to bronchoalveolar lavage samples provided valuable information at hour 24. The primary objective of this study was to assess a new direct specimen testing by using an even more-rapid E-test approach (at hour 10), which could promote an early de-escalation of the antimicrobial therapy. ⋯ This rapid susceptibility testing approach provided early (10 h) and valuable information that could lead to an early adjustment of empirical antimicrobial treatment in a ventilator-associated pneumonia setting.
