Twenty-two women participated in a modified replicate study which examined the effects of prenatal maternal attachment behaviors during first pregnancies. A pretest reflected the degree of maternal-fetal attachment behaviors and attitudes already formed. The women in the experimental group received three interventions aimed at directing the mothers' attentions toward their fetuses. The remaining women received routine prenatal care only. All mothers were observed once in the first few days postpartum to assess maternal attachment behaviors. Data analysis did not substantiate the findings of the earlier study. Factors identified in the added pretest may have accounted for this difference.

Teaching strategies used by expert nurse practitioner preceptors: a qualitative study.

Nurse practitioner (NP) programs utilize expert clinicians as preceptors for their students. Little is written regarding this important role. This study explored teaching strategies used by expert preceptors. Fifteen preceptors in a master's level NP program participated in this qualitative study. The study identified (a) orientation strategies, (b) strategies used with all students, and (c) strategies used differentially according to level of learner. Two distinct preceptor styles emerged from the data ("incremental structure" and "sink or swim"). Preceptors also identified characteristics of student readiness for increased responsibility. Results of this qualitative study can be helpful in preceptor orientation and continued education.

Neonatal equine herpesvirus type 1 infection on a thoroughbred breeding farm.

Of 17 foals born on a Thoroughbred breeding farm between March and April 1995, infection with equine herpesvirus type 1 (EHV-1) was associated with neonatal morbidity in 5 foals, 3 of which died or were euthanized. Morbidity and mortality were associated with pulmonary inflammation, and EHV-1 was identified in the lungs of the 3 foals that died. All neonatal EHV-1 infections occurred in foals of mares housed in the same pasture and barn. No other clinical manifestations of EHV-1 infection (e.g., abortion, neurologic disease, or respiratory disease) occurred during this outbreak. Three foals were treated with acyclovir (1 died, 2 survived), which may have influenced the clinical outcome in the surviving foals.

Efficacy of omeprazole for the prevention of exercise-induced gastritis in racing Alaskan sled dogs.

Exercise-induced gastritis and gastric ulcers are common in humans and horses, and recently have been described in racing sled dogs. The cause of exercise-induced gastric disease is not completely understood in any species, but pharmacologic suppression of acid secretion is an effective treatment in humans and horses. Thus, we tested the hypothesis that omeprazole, a proton-pump inhibitor shown to reduce gastric acid secretion in dogs, would reduce the severity of exercise-induced gastric disease. Three teams of 16 dogs each competing in the 2002 Iditarod Sled Dog Race were recruited for participation. Within each team, dogs were randomly assigned to either treatment (20 mg omeprazole PO q24h) or placebo. Treatments were administered until either completion of the race or withdrawal of an individual dog from competition. Gastric endoscopy was performed in all dogs 24 hours after completion or withdrawal, and the gastric mucosa was scored by using a subjective severity score (0 = normal, 3 = numerous bleeding ulcers). Treatment with omeprazole significantly reduced mean gastric severity score compared to placebo (omeprazole: 0.65 +/- 0.17, placebo: 1.09 +/- 0.18; P = .028), but also was associated with increased frequency of diarrhea during the race (omeprazole 54%, placebo 21%; P = .017). Examination of our data suggests that omeprazole may be an effective treatment for exercise-induced gastric disease in racing sled dogs. However, further investigation regarding the cause and clinical relevance of diarrhea associated with omeprazole treatment must be conducted before omeprazole can be recommended for routine prophylactic treatment in these athletes.

Prevalence of gastric lesions in racing Alaskan sled dogs.

Human and equine athletes are reported to have a high prevalence of gastric disease, and anecdotal evidence suggests a similar phenomenon applies to racing sled dogs. To investigate the prevalence of gastric disease in racing sled dogs, we conducted 2 gastroscopy studies on dogs competing in the annual Iditarod Sled Dog Race. A pilot study of dogs that were either dropped from the 2000 Iditarod Sled Dog Race because of illness or that finished the race indicated that, approximately 5 days after competing, 10 of 28 dogs (35%) had endoscopic evidence of gastric ulceration, erosion, or hemorrhage. The next year, an endoscopic study of 73 dogs participating in the 2001 Iditarod race was performed in order to evaluate a larger population of dogs. Data from 70 of these dogs could be used; 34 (48.5%) had ulceration, erosion, gastric hemorrhage, or some combination of these findings. When this group of 70 dogs was compared retrospectively to a control group of 87 dogs presented to the Texas A&M University (TAMU) Veterinary Medical Teaching Hospital, the Iditarod sled dogs had a significantly higher prevalence (P = .049) of gastric lesions. These findings suggest that, similar to athletes of other species, elite canine athletes have an increased prevalence of gastric disease compared to the canine population at large.
