Perivascular Adipose Tissue: A Novel Regulator of Vascular Tone in the Rat Pregnancy.

Perivascular adipose tissue (PVAT) contributes to vasoregulation. The role of this adipose tissue bed in pregnancy has not been examined. Here, we tested the hypothesis that PVAT in pregnant rats decreases resistance artery tone.

The impact of premorbid conditions on temporal pattern and location of adult blunt trauma hospital deaths.

Background: This study was designed to show the importance of age, presence of premorbid conditions, and the type of injury on time and location of adult inhospital trauma mortality.

Methods: All acute blunt trauma deaths at a Level I urban trauma center between April 1, 1993 and March 31, 2003 were individually reviewed to collect data on the following variables: age, gender, presence and number of premorbid conditions, mechanisms of trauma, location of death, acute transfer from another hospital, delay to death, initial Glasgow Coma Score (GCS), Abbreviated Injury Score (AIS), Injury Severity Score (ISS), and revised trauma score (RTS). Bivariate analysis using simple logistic regression was used to show the association between each variable and delay to death.

Surgical management of blunt thoracic and abdominal injuries in Quebec: a limited volume.

Background: Trauma care of thoracic and abdominal injuries is currently in turmoil because of both a decrease in the number of these injuries and a concomitant increase in their nonsurgical management. The goal of this study was to evaluate the incidence of thoracic and abdominal injuries in the province of Quebec and the number of associated surgical procedures.

Methods: Patients with blunt thoracic or abdominal injuries taken to a tertiary trauma center in the province of Quebec from April 1, 1998 to March 31, 2002 were identified.

Is the delay to surgery for isolated hip fracture predictive of outcome in efficient systems?

Background: Adverse outcomes for patients with isolated hip fracture have been documented when preoperative delay is longer than 48 hours. An efficient system will have the capacity to repair all hip fractures within 48 hours. We hypothesized that in an efficient system, there would be a medical justification for a delay greater than 48 hours.

Paying the price of excluding patients from a trauma registry.

Background: The goal of this study was to evaluate the impact of different trauma registry exclusion criteria on the assessment of trauma populations and outcome.

Methods: All patients admitted to a Canadian regional trauma center from April 1, 1993 to March 31, 2002 with a diagnosis of trauma (ICD-9 codes 800 to 959) were reviewed. TOTAL included everyone.
