Randomized Controlled Trial
Targeted Fluid Minimization Following initial Resuscitation in Septic Shock: A Pilot Study.
IV fluid represents a basic therapeutic intervention for septic shock. Unfortunately, the optimal administration of IV fluid to maximize patient outcomes and prevent complications is largely unknown. ⋯ This pilot study suggests that TFM in patients with septic shock can be performed using protocol-guided assessments of fluid responsiveness. Larger trials of TFM in septic shock are needed.

Pulse oximetry fails when pulsations are weak or absent, common in patients with continuous flow left ventricular assist devices (LVADs). We developed a method to measure arterial oxygenation (Sao2) noninvasively in pulseless patients with LVADs. ⋯ Preliminary results in a small number of patients demonstrate that pulseless oximetry can be used to estimate arterial saturation with acceptable accuracy. A noninvasive oximeter that does not rely on pulsatile flow would be a valuable advance in assessing oxygenation in patients with LVADs, for whom the only current option is arterial puncture, which is painful, risks arterial injury, and only provides a snapshot evaluation of oxygenation.

Lung-dominant connective tissue disease (LD-CTD) is a disease concept for interstitial pneumonia; however, it has not been robustly validated. This study was conducted to elucidate the clinical, radiologic, and histologic features of LD-CTD. ⋯ The major histologic patterns in LD-CTD were UIP followed by NSIP. Two-thirds of patients had characteristic histologic features for LD-CTD. A majority of patients with h-UIP were considered to have unclassifiable IIP based on MDD. Patients with h-UIP had worse survival than those with h-NSIP.

Seven years after left hemicolectomy and radical lymph nodal dissection followed by adjuvant chemotherapy for colorectal cancer (histotype, adenocarcinoma; stage, pT3N2M0; grading, G2), a slight increase in carcinoembryonic antigen levels (6.2 ng/mL; range, 0-5 ng/mL) was detected in a 79-year-old man. He was a heavy smoker with history of an interstitial fibrotic lung disease with associated areas of emphysema.
