The authors prospectively investigated stress in 71, mostly European American pregnant women. Conservation of Resources (COR) theory was applied to assess the impact of resource losses and gains that occur in women's lives. Resources were defined as…
Study Design. A description of the technique for lumbar microdecompression and a prospective study of the outcomes. Objective. To describe and analyze a technique that affords an excellent decompression while minimizing damage to surrounding tissues.…
New fossils discovered south of the Turkwel River in northern Kenya include an associated metacarpal, capitate, hamate, lunate, pedal phalanx, mandibular fragment, and teeth. These fossils probably date to around 3.5 m.y.a. Faunal information…
Amphibians overwintering in ice-covered aquatic environments encounter levels of hypoxia that present significant challenges to the maintenance of aerobic metabolism. Earlier laboratory experiments showed that cold-submerged frogs will seek out lower…
Study Design, Caudal vertebrae were obtained from male and female mice from two transgenic lines expressing an erythroid-specific human growth hormone-transgene construct, and gender-matched, age-matched, nontransgenic control mice. Objective. To…
In the present study, [H-3]nisoxetine binding to norepinephrine (NE) uptake sites and [H-3]norepinephrine uptake were investigated within olfactory bulb (OB) and frontal cortex homogenates from intact and castrated male rats. Statistically…
Career development theory provides a comprehensive model for conceptualizing the school-to-work transition. Since the 1920s, this model has guided the design of a plethora of career education methods and materials that orient, teach, coach, and…
Objectives: This study was performed to complement studies on spondyloarthropathy in rhesus macaques by quantifying and characterizing another major form of arthritis and contrasting it with osteoarthritis. Methods: Skeletons of 269 macaques of known…
Recognition of cancer in extreme antiquity has been limited to osteomas in mosasaurs and haemangiomas and growths of unclear origin in dinosaurs. We describe a metastatic cancer in a dinosaur.
Objectives:This study assessed the impact of organizational reengineering on nursing in a large community teaching hospital in the Midwest, using an observational repeated measures design. Time, clinical unit, and nurse characteristics were…
Gastrointestinal bleeding is a common and potentially life-threatening problem. The incidence of upper gastrointestinal bleeding (UGIB) is 40 to 150 episodes per 100,000 population per year.(19, 73, 77) Mortality in large series is 6% to 10% for UGIB…
In an era of competition in health care delivery, those who pay for care are interested in supporting primarily those activities that add value to the clinical enterprise. The authors report on their 1998 project to develop a conceptual model for…
The efficacy of amphotericin B bladder irrigation at two concentrations was studied. Patients with funguria (greater than or equal to 15,000 colony-forming units of yeast per milliliter of urine), an indwelling urinary catheter, and a physician order…
Over the last decade, the incidence of penicillin resistance among Streptococcus pneumoniae isolates has markedly increased. This trend is unsettling because infections caused by S pneumoniae are among the leading causes of morbidity and mortality in…
Multidisciplinary focus groups were convened in three geographically diverse areas of Ohio to compare the application of guardianship and adult protective services interventions in the lives of vulnerable adults. The results suggest that there is…
Statistics tell us that as many as 1 in 20 members of the population will suffer a seizure at some point in their lifetime, a figure which becomes even more likely if one lives to the age of 80. Thus, a careful evidence based approach to the patient…
Dislocations of the shoulder are the most common joint dislocations seen in the emergency department, and complications of shoulder dislocations are more frequent than is generally believed. It is vital that emergency physicians have current…
The Infectious Diseases Society of America advocates using pathogen-directed therapy whenever possible to help reduce the emergence of drug resistance. Options for empiric therapy for outpatients include a macrolide, a new fluoroquinolone with…
The Infectious Diseases Society of America (IDSA) recently published updated guidelines for assessing and treating patients with community-acquired pneumonia. In contrast to the common practice of treating patients on the basis of clinical…
PURPOSE: To examine parental perceptions and behaviors with regard to teen smoking, comparing African-American and white parents, and those who did and did not smoke. METHODS: Focus groups consisting of African-American and white parents who smoked…
Oxysterol 7alpha-hydroxylase has broad substrate specificity for sterol metabolites and may be involved in many metabolic processes including bile acid synthesis and neurosteroid metabolism. The cloned human oxysterol 7alpha-hydroxylase (CYP7B1) cDNA…
At the low temperatures of the overwintering environment of the frog Rana temporaria, small changes in ambient temperature have large effects on metabolism and behaviour, especially since Q10 values are often greatly elevated in the cold. How the…
The 'atypical' pathogens are important causes of pneumonia, causing illness ranging from mild to life-threatening. The most common atypical pathogens are Mycoplasma pneumoniae and Chlamydia pneumoniae; others include Legionella species, Chlamydia…
