The current usual interstitial pneumonitis (UIP)/idiopathic pulmonary fibrosis CT scan classification system excludes probable UIP as a diagnostic category. We sought to determine the predictive effect of probable UIP on CT scan on histology and the effect of the promoter polymorphism in MUC5B (rs35705950) on histologic and CT scan UIP diagnosis. ⋯ Probable UIP on CT scan is associated with a higher rate of histologic UIP than indeterminate UIP on CT scan suggesting that they are distinct groups and should not be combined into a single CT scan category as currently recommended by guidelines. CT scan and microscopic honeycombing may be dissimilar entities. The T allele at rs35705950 predicts a UIP diagnosis by both chest CT scan and histology.

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.

Therapeutic hypothermia after cardiac arrest in a patient with systemic sclerosis and raynaud phenomenon.
Therapeutic hypothermia favorably impacts neurologic outcomes in patients after cardiopulmonary arrest, although the appropriate target temperature is less clear. Its safety profile in patients with systemic sclerosis (SSc) and Raynaud phenomenon (RP), who may be at increased risk for ischemic complications, has not been addressed in the literature, to our knowledge. Digital lesions are commonly seen in patients with SSc, and cold-induced myocardial ischemia has also been reported. ⋯ He regained full neurologic function, and except for digital necrosis, no hypothermia-associated adverse events were observed. Other risk factors for ischemia, such as cocaine use, may have contributed to the development of the digital necrosis. However, clinicians should be aware of the risk for ischemic complications in patients with SSc and RP when considering the appropriate target temperature after cardiopulmonary arrest.

No study has determined whether the risk of mortality predicted by the GAP (gender, age, and physiologic variables) model matches the observed mortality from idiopathic pulmonary fibrosis (IPF) in non-Western populations. We evaluated the clinical course of IPF and validated the GAP model in Korean patients with IPF. ⋯ The GAP model showed similar discrimination power compared with the original cohort but did not predict the 3-year risk of death accurately. Further multinational validation studies are needed.

Palliative care, integrated early, may reduce symptom burden in patients with idiopathic pulmonary fibrosis (IPF). However, limited information exists on timing and clinical practice. The purpose of this study was to describe the time course of events prior to death in patients with IPF managed at a specialty center with a focus on location of death and timing of referral for palliative care. ⋯ The majority of patients with IPF died in a hospital setting and only a minority received a formal palliative care referral. Referral to palliative care occurred late in the disease. These findings indicate the need to study adequacy of end-of-life management in IPF and promote earlier discussion and referral to palliative care.
