Endometrial vascular changes and bleeding disturbances with long-acting progestins.

Unscheduled disturbances of bleeding with long-acting progestogen-only methods continue to be a major social inconvenience, and the most common reason for premature discontinuation of use. The patterns of bleeding with different methods are now well characterised, but in spite of a substantial amount of recent research we still do not clearly understand the actual mechanisms underlying these disturbances. The major changes occur locally within the endometrium, although these are influenced substantially by different dosages and regimens of contraceptive steroids. Hysteroscopic studies have demonstrated major changes in the extent of superficial endometrial vascularization, disturbances in superficial vascular morphology, and increased endometrial vascular and epithelial fragility in progestogen-only users. There may also be alterations in endometrial perfusion and vasomotion. Laboratory studies of cellular and molecular mechanisms have shown changes in vascular basement membranes, pericytes, migratory leukocytes, cellular architecture, cell adhesion molecules, and intercellular matrix breakdown systems, such as matrix metalloproteinases. It appears that continuous exposure to progestogen, in the presence of low to moderate levels of estrogen, results in an endometrium that histologically demonstrates 'suppressed secretory' changes, associated with disturbed angiogenesis, and a tendency to release molecules capable of causing focal endometrial epithelial and endothelial damage and bleeding.

Appointment, promotion, and tenure criteria to meet changing perspectives in healthcare.

With anticipated changes in healthcare delivery systems, nursing faculty members need to redefine the faculty role and scholarship as a product of that role. The authors describe the development of appointment, promotion, and tenure criteria that value scholarly outcomes generated from both practice and research within the educational model.

Aerobic dance injuries.

Aerobic dance has taken the spotlight as one of the most popular forms of exercise in America. The benefits of a well developed, comprehensive program include an increase in strength, flexibility, and endurance while promoting a healthy cardiovascular system. Orthopaedic nurse clinicians frequently come in contact with aerobic dance participants before and after injury occurs. This article discusses the occurrence of aerobic dance injuries, treatment, and prevention.

Spondylolisthesis in children and adolescents.

Spondylolisthesis in children and adolescents can present in various ways and have a wide range of treatment options. Children are not "little adults." They require special interview, evaluation, and treatment considerations. This article addresses the characteristics of spondylolisthesis in children and reviews some of the treatment options and related nursing considerations.

The next iteration of managed care? Panel discussion.

What did our five panelists predict for the next iteration of managed care? What do they see happening now? What will the health care industry look like in ten years? Employers will shift an increasing share of rising medical and prescription drug costs to consumers through higher co-pays and defined contributions. Some providers may market their services to attract these consumers. Tightly managed HMOs will provide access to lower-income consumers. So for, e-health is helping managed care organizations cut administrative costs, but not medical expenses. Genetic testing and therapies will not be commercially available for ten to 15 years. Based on demographic trends and labor shortages, demand is likely to exceed the capacity of the health care system within the next three decades. Our five experts caution that managed care is as unpredictable and chaotic as ever, but they do their best to tell you how they think it'll all play out in the near term.
