Perceptions and Utilization of Strength Training and Conditioning in Collegiate Contemporary and Ballet Dancers: A Qualitative Approach.

Aims: Research demonstrates that dancers benefit from reduced injury risk and improved health by engaging in strength training and conditioning (STC). Historic bias within the discipline of dance, however, establishes a long-standing stigma that gains in muscle mass and strength lessen a dancer's aesthetic appearance, and thus many dancers rebuff STC as a supplement to dance training. However, there is growing evidence that dancers and dance educators are beginning to under¬stand the importance of additional resistance training and cardiovascular conditioning.

Design: Randomized controlled clinical trial.

Orthotic intervention and postural stability in participants with functional ankle instability after an accommodation period.

Implementing projects using the rapid-cycle approach.

The Quality Work Out, a rapid-cycle improvement initiative, was put into place to prepare a complex 5-hospital system for The Joint Commission and the concept of the "next patient." The patient care team, a group of 11 change agents, was tasked with developing, leading, and implementing projects using the rapid-cycle approach. The authors outline key strategies that led to a successful The Joint Commission survey and measurable change at the bedside.

Successful treatment of mediastinal gas gangrene due to esophageal perforation.

Esophageal perforation and mediastinal gas gangrene developed in a 55-year-old male after the endoscopic ethanol injection of a Mallory-Weiss ulcer. Initially, extensive gangrene of the esophagus and the mediastinum was treated by esophagectomy; however, an abundance of Clostridium perfringens in the Gram stain verified the presence of gas gangrene. Subsequently, the patient was transferred to a hyperbaric oxygen center, wherein a total of seven hyperbaric treatments were administered.

Ten professional divers went through two hyperbaric hyperoxic experiments: (1) hyperbaric oxygen (HBO), 100% oxygen at 2.5 ATA, (2) hyperbaric air (HBAIR), O(2) 21% at 2.

Importance of storing emergency serum samples for uncovering murder with insulin.

A case of a previously healthy 48-year-old man murdered by exogenous insulin administration is reported. The patient was delivered unconscious to the emergency unit. Initially, treatment with hyperbaric oxygen was commenced because decompression sickness was suspected.

Heart rate variability in healthy volunteers during normobaric and hyperbaric hyperoxia.

Inhaled supranormal partial pressure of oxygen induces bradycardia and peripheral vasoconstriction. The exact mechanism of the decreasing heart rate is not clear, but the autonomic nervous system is partly involved.

Continuous positive airway pressure with and without high-frequency ventilation: hemodynamics, oxygenation, and endocrine response.

After 18 h of mechanical ventilation following open heart surgery, central hemodynamics, systemic oxygen delivery (DO2), and oxygen consumption were assessed in ten consecutive patients receiving continuous positive airway pressure (CPAP) therapy. Plasma vasopressin, norepinephrine, and epinephrine levels were analyzed. While maintaining the mean airway pressure, two CPAP methods were studied: a demand CPAP with continuous flow without (CPAP) and one with high-frequency ventilation (CPAP-HFV).
