Hypothermia is an independent risk factor for prolonged ICU stay in coronary artery bypass surgery: an observational study.

Maintenance of normothermia is a critical perioperative issue. The warming process after hypothermia tends to increase oxygen demand, which may lead to myocardial ischemia. This study explored whether hypothermia was an independent risk factor for increased morbidity and mortality in patients receiving CABG.

Pandemic acquired competitive traits from an environmental species.

is a human pathogen that thrives in estuarine environments. Within the environment and human host, uses the type VI secretion system (T6SS) to inject toxic effectors into neighboring microbes and to establish its replicative niche. strains encode a wide variety of horizontally shared effectors, but pandemic isolates encode an identical set of distinct effectors.

Genomes of Vibrio metoecus co-isolated with Vibrio cholerae extend our understanding of differences between these closely related species.

Background: Vibrio cholerae, the causative agent of cholera, is a well-studied species, whereas Vibrio metoecus is a recently described close relative that is also associated with human infections. The availability of V. metoecus genomes provides further insight into its genetic differences from V.

Second Adjuvant Radioiodine Therapy after Reoperation for Locoregionally Persistent or Recurrent Papillary Thyroid Carcinoma.

 Differentiated thyroid carcinoma (DTC) has increased incidence. Intermediate- and high-risk patients have lymph node relapse rate ranging from 10 to 50%, and receive multiple reinterventions, increasing the morbidity of the disease. Currently, there are no established guidelines for the use of second radioactive iodine (RAI) therapy after the reintervention for local recurrence.
