Reliability of measured tidal volume in mechanically ventilated young pigs with normal lungs.

Objective: This study examined whether volumes can be accurately measured at the expiratory valve of a conventional ventilator using pressure support ventilation and positive end expiratory pressure with software compensation for circuit compliance available in the Servo iota ventilator.

Design And Setting: Comparison of two methods for measuring tidal volume in an animal laboratory.

Subjects: Twenty healthy, intubated, sedated, spontaneously breathing pigs.

Validation of a noninvasive blood pressure monitoring device in normotensive and hypertensive pediatric intensive care patients.

Objective: To evaluate the performance and to define limitations of a noninvasive blood pressure monitoring device in the critically ill pediatric population.

Method: Patients were included in the study if they were admitted to the Pediatric Intensive Care Unit, were between the ages of 1 month and 18 years with wrist circumferences of > or =10 cm, and had an indwelling arterial line. Patients were excluded if their systolic blood pressure differed by > or =7.

Soy immunotherapy for peanut-allergic mice: modulation of the peanut-allergic response.

Background: Allergen-specific immunotherapy (IT) is an effective therapeutic modality to prevent further anaphylactic episodes in patients with insect sting hypersensitivity and is being investigated for peanut allergy. So far, peanut-specific IT has been unsuccessful because of the side effects of therapy. Soybean seed storage proteins share significant homology with the respective peanut allergens.

Effects of continuous positive airway pressure/positive end-expiratory pressure and pressure-support ventilation on work of breathing, using an animal model.

Objective: Evaluate the effects of continuous positive airway pressure (CPAP)/positive end-expiratory pressure (PEEP) and pressure support ventilation (PSV) on work of breathing (WOB).

Methods: With 13 anesthetized lambs we measured WOB with an esophageal balloon and flow signals. All the animals were sedated, intubated, and ventilated, using 2 pediatric ventilators (Servo 300 and VIP Bird).

Recruitment of Hispanic women to the Women's Health Initiative. the case of Embajadoras in Arizona.

This study examined the use of lay advocates (i.e., women enrolled in a study who advocate to others) to improve recruitment among Hispanic women in the Arizona recruitment sites for a large-scale, national prevention study, the Women's Health Initiative (WHI).

Usage of supplemental alternative medicine by community-based patients with gastroesophageal reflux disease (GERD).

There is an increasing trend towards alternative medicine usage by the general US population. However, the extent and type of supplemental alternative medicine used specifically by community-based patients with GERD is unknown. A previously validated questionnaire that included questions about patient demographics, 18 types of alternative medicine, and attitudes towards alternative and conventional medicine was utilized.
