Casaer et al randomized 4,640 critically-ill patients who could not get enough calories by enteral feeding to receive TPN either on ICU day 3, or to wait until ICU day 8.

Zager et al examined registry data on 38,917 patients admitted to Beth Israel and Brigham & Women’s hospitals between 1997-2007, and concluded that low socioeconomic status (as determined by census tract neighborhood of residence) did not influence 30- or 365-day mortality after admission to these hospitals’ ICU.

Hargreave and Nair (PRO) argue the boutique technique is underrated and underused, citing trials showing improvement in severe asthma outcomes when sputum eosinophils are used to guide therapy (1, 2, and studies on IL-5 blockers).

Menthol doesn’t kill people — cigarettes that are tastier and easier to smoke because of menthol do.

In severe congestive heart failure, lymphatic drainage can increase 10-fold. Pastis et al hypothesize this could result in enlarged mediastinal lymph nodes. They retrospectively examined chest CT scans for 118 patients undergoing heart transplantation. Fifty-three had mediastinal LNs > 1 cm. In the 9 who had post-transplant CT scans available, mediastinal lymph nodes shrank after [... read more]

Masclans et al followed 38 patients with ARDS in 3 ICUs for 6 months. Health-related quality of life (Nottingham Test Profile) was lower than expected at 6 months, with 40% reporting limitations in daily activities mainly due to low energy, mobility and social functioning. Mild radiographic abnormalities and restrictive physiology were usually present on HRCT [... read more]

Actuarial survival in PAH has been predicted mainly by functional class and echocardiographic evidence of right heart failure. Observing 484 patients with WHO group I PAH for 5 years after diagnosis, Kane et al showed that using their own multivariate model (incorporating clinical data including renal function, BNP, DLCO, BP & HR, etc.) generated better [... read more]
