Infectious diseases acquired by survivors of large-scale natural disasters complicate the recovery process. During events such as tsunamis, hurricanes, earthquakes, and tornados and well into the recovery period, victims often are exposed to water-soil mixtures that have relocated with indigenous microbes. ⋯ Moreover, we show an increased number of positive NTM cultures from Louisiana residents in the years following three of the relatively recent epic hurricanes and posit that such natural disasters may help to drive the increased number of NTM infections. Finally, we advocate for increased environmental studies and surveillance of NTM infections before and after natural disasters.

Diabetes mellitus (DM) increases the risk of TB recurrence. This study investigated whether 9-month anti-TB treatment is associated with a lower risk of TB recurrence within 2 years after complete treatment than 6-month treatment in patients with DM with an emphasis on the impact of directly observed therapy, short course (DOTs). ⋯ The 2-year TB recurrence rate is higher in a diabetic population in Taiwan and can be reduced by treatment supervision. Extending the anti-TB treatment by 3 months may also decrease the recurrence rate when treatment is not supervised.

The clinical presentation and outcome of sarcoidosis varies by race. However, the race difference in mortality outcome remains largely unknown. ⋯ This nationwide population-based study exposes a significant difference in ethnicity and sex among people dying of sarcoidosis in the United States. Pulmonary hypertension investigation should be considered in all patients with sarcoidosis, especially African Americans.

A multicenter study in the late 1990s demonstrated suboptimal emergency asthma care for pregnant women in US EDs. After a decade, follow-up data are lacking. We aimed to examine changes in emergency asthma care of pregnant women since the 1990s. ⋯ Between the two time periods, emergency asthma care in pregnant women significantly improved. However, with one in three pregnant women being discharged home without systemic corticosteroids, further improvement is warranted.

Routine lung function and respiratory muscle testing are recommended in children with neuromuscular disease (NMD), but these tests are based on noninvasive volitional maneuvers, such as the measurement of lung volumes and maximal static pressures, that young children may not always be able to perform. The realization of simple natural maneuvers such as a sniff or a cough, and the measurement of esophageal and gastric pressures during spontaneous breathing can add valuable information about the strength and endurance of the respiratory muscles in young children. Monitoring respiratory muscles in children with NMD may improve understanding of the natural history of NMD and the evaluation of disease severity. It may assist and guide clinical management and it may help the identification and selection of optimal end points, as well as the most informative parameters and patients for clinical trials.
