Association of Oncogene Driver Mutations with Recurrence and Survival in Stage I Nonsmall Cell Lung Cancer.

Background: Stage I nonsmall cell lung cancer (NSCLC) is primarily treated with surgical resection and has a favorable prognosis with an expected recurrence rate of 30%. New methods to risk stratify patients with stage I NSCLC are needed to help select those that might benefit from more active surveillance or adjuvant therapy.

Methods: We analyzed clinical data from 1330 patients (1469 tumors) with NSCLC and correlated it with next-generation sequencing (NGS).

Imatinib Treatment of Lymphangiomatosis (Generalized Lymphatic Anomaly).

Lymphangiomatosis (eg, generalized lymphatic anomaly) is an abnormal proliferation of lymphatic endothelial cells. It is often a childhood disease, but it may present in adulthood by infiltrating organs and cause obstruction, bleeding, or disruption of lymphatic flow. Pulmonary involvement may be mild or cause diffuse interstitial lung disease, airway obstruction, hemoptysis, chylothorax, chylopericardium, and culminate in respiratory failure.

Surgical lung biopsy in adult respiratory distress syndrome: a meta-analysis.

Background: Adult respiratory distress syndrome (ARDS) has a high mortality rate and consumes considerable health care resources. It is not clear whether specimens obtained from open lung biopsy (OLB) in ARDS provide a specific diagnosis, alter therapy, or affect outcome. This meta-analysis attempts to determine whether OLB is safe, provides a specific diagnosis, changes therapy, or affects survival.

QTL associated with blood pressure, heart rate, and heart weight in CBA/CaJ and BALB/cJ mice.

To better understand the genetic basis of essential hypertension, we conducted a quantitative trait locus (QTL) analysis of a population of 207 (BALB/cJ x CBA/CaJ) F(2) male mice to identify genomic regions that regulate blood pressure, heart rate, and heart weight. We identified two loci, Bpq6 (blood pressure quantitative locus 6) on chromosome 15 (Chr 15; peak, 16 cM; 95% confidence interval, 0-25 cM) and Bpq7 on Chr 7 (peak, 42 cM; 95% confidence interval, 35-50 cM) that were significantly associated with blood pressure. We also identified two loci, Hrq1 (heart rate quantitative locus 1) and Hrq2, on D2Mit304 (peak, 72 cM; 95% confidence interval 60-80 cM) and D15Mit184 (peak, 25 cM; 95% confidence interval 20-35 cM), respectively, that were significantly associated with heart rate.
