Aerobics enhances cardiovascular fitness and agility in preschoolers.

Investigated effects of aerobic exercise on a sample of 24 preschoolers. Thirty minutes of aerobic exercises were provided daily for a period of 8 weeks for a group of 12 children while the remaining 12 children engaged in freeplay on the school playground. The children were given pretests and posttests on the following measures: a submaximal exercise test on a pediatric bicycle (baseline and three workloads), an agility test, a health knowledge test, a self-esteem scale, and an observational measure of their gross-motor activity. Despite comparability on pretests, significant group X repeated measures effects suggested that the aerobic exercise group showed decreases in heart rate at all three workloads as well as increases in agility and self-esteem following the exercise program. These findings suggest that cardiovascular fitness, agility, and self-esteem can be facilitated in preschoolers by an aerobic exercise program.

Alleviating stress in newborn infants in the intensive care unit.

Potentially stressful features of the neonatal intensive care environment, including factors such as continuous high-intensity noise and bright light, have generated concern. Some neonatal researchers have speculated that the intensive care nursery constitutes a source of sensory deprivation, whereas others have suggested that the preterm infant is overestimated or experiences an inappropriate pattern, rather than an excessive amount, of stimulation. This article examines some of the sources of stress in the neonatal intensive care unit.

Right hemisphere contribution to lexical access in an aphasic with deep dyslexia.

Three hemifield tachistoscopic studies of a right-handed patient with acquired Broca's aphasia and deep dyslexia, but with intact visual fields, are presented to support the hypothesis of right hemisphere (RH) participation in deep dyslexic reading. A systematic comparison of this deep dyslexic with the disconnected RHs of two patients with complete cerebral commissurotomy disclosed a similar, but not identical, pattern of abilities. The results demonstrate partial reliance on the RH for accessing the meaning of single words, but not for phonological encoding in this patient.

Hospitalization stress in children: sensitizer and repressor coping styles.

To examine the effects of individual sensitizer/repressor coping styles on responses to hospital procedures, 56 children (mean age = 6.5 years) were observed during hospitalization for minor surgery. Although the sensitizer children, as classified by their mothers, did not differ from the repressor children on baseline measures including hospital preparation, they were more talkative, expressive, and active during hospital play observations. During blood tests and preoperative injections, the sensitizers, compared with the repressors, were reported by their mothers to observe the procedures, to seek additional information about the procedures, and to show more protest behaviors. Finally, the sensitizer children required fewer hours of intensive care.

Infants of depressed mothers show "depressed" behavior even with nondepressed adults.

To determine whether the "depressed" behavior (e.g., less positive affect and lower activity level) of infants noted during interactions with their "depressed" mothers generalizes to their interactions with nondepressed adults, 74 3-6-month-old infants of "depressed" and nondepressed mothers were videotaped in face-to-face interactions with their mothers and with nondepressed female strangers. "Depressed" mothers and their infants received lower ratings on all behaviors than nondepressed mothers and infants. Although the infants of "depressed" versus nondepressed mothers also received lower ratings with the stranger adult, very few differences were noted between those infants' ratings when interacting with their mother versus the stranger, suggesting that their "depressed" style of interacting is not specific to their interactions with depressed mothers but generalizes to their interactions with nondepressed adults as early as 3 months of age.

Attitudes of persons at risk for Huntington disease toward predictive testing.

Attitudes of 69 persons at risk for Huntington disease (HD) were obtained by means of semistructured interviews and questionnaires. About 79% of the individuals said that they would use a presymptomatic predictive test if it were available. All believed that the test should be made available even though there was no cure for HD. Nearly 2/3 of subjects would use the test for prenatal diagnosis, and of these 71% would terminate a pregnancy if the fetus was found to carry the HD gene. Most subjects believed that pretest counseling should be mandatory and many said that testing should be withheld from persons who were psychologically unstable or were threatening self-harm. The data suggest that about 2-6% of persons at risk for HD may have severe psychiatric or suicidal responses to a positive outcome of predictive testing. This underscores the need for adequate pretest counseling and the availability of professional and community resources to deal with the impact of predictive testing on individuals and their relatives.

Rotated hypoplastic hemipelvis: a cause of obstructive dyspareunia.

Repeat Chiari innominate osteotomy in a young woman with traumatic monoplegia and subsequent hypoplasia of the hemipelvis and leg resulted in rotation of the pubic ramus into the vagina, causing obstructive dyspareunia. Resection of the inferior pubic ramus through a transperineal approach allowed successful intromission with resolution of her dyspareunia.

Technology under Medicare diagnosis-related groups prospective payment. Implications for medical intensive care.

Medicare prospective payment by diagnosis-related groups (DRGs) has intensified the debate over the use and costs of medical technology. In this study, we examine the financial impact of DRG payment for medicare patients receiving medical intensive care. During a one-year period, payment for 446 Medicare patients receiving medical intensive care at a large teaching hospital was calculated to be +4.7 million below costs, representing an average loss per discharge of +10,567. Patients stayed an average of 21.6 days including an average of 5.0 days in the medical intensive-care unit--23 percent of the total stay. Twenty-eight percent of the MICU patients died during hospitalization. For this group, the average payment per discharge was projected to be +21,651 below the average per discharge cost. We conclude that the results send strong financial messages to hospitals providing medical intensive care to severely ill, elderly patients. Further exploration and research must occur to ensure hospital responses will be consistent with public policy expectations.

Effects of ultrasound feedback on pregnancy anxiety, fetal activity, and neonatal outcome.

A group of pregnant women received video and verbal feedback during three ultrasound examinations. This group was compared with a no-feedback group on measures of pregnancy anxiety, fetal activity, and neonatal outcome. The feedback appeared to reduce pregnancy anxiety and fetal activity, particularly for the primiparous women. These women also experienced fewer obstetric complications and gave birth to neonates who were greater weight, more appropriate weight-for-length, less active and irritable, and showed better performance on the Brazelton neonatal behavior assessment.

Children's responses to separation from mother during the birth of another child.

Preschool children's behavioral and physiological responses to separation were monitored before, during, and after their mothers' hospitalization for the birth of a sibling. During these 3 periods, play sessions were videotaped simultaneous with activity level and heart rate monitoring, nighttime sleep was time-lapse videotaped, and the parents were administered questionnaires on changes in their child's behaviors. Increases in fantasy play across these periods were interpreted as active coping both with the stress of separation and the altered interactions following the arrival of a new sibling. Increases in negative affect, activity level, heart rate, night wakings, and crying characterized the hospital period as one of agitation. Longer periods of deep sleep at this stage were interpreted as conservation withdrawal. Following the mother's return, decreases were noted in positive affect, activity level, heart rate, and active sleep suggestive of depression. These changes are discussed in the context of parallel data on agitation/depression during young primate separations.

Pacifying effects of nonnutritive sucking on term and preterm neonates during heelstick procedures.

Behavioral state, heart rate, and respiration were monitored during heelstick procedures in samples of healthy, term neonates (N = 48) and preterm neonates treated in minimal care (N = 48) and intensive care (N = 48) nurseries. The treated infants who were given pacifiers spent significantly less time fussing and crying during and following the heelstick procedures. Physiologic arousal was monitored in both preterm groups but was attenuated only in the preterm infants who received pacifiers (minimal care group). As similar amounts of sucking were observed in both preterm groups, the inconsistency in treatment effects on behavioral and physiologic arousal was interpreted as a lack of cardiac-somatic coupling in the neonate in intensive care. Results suggest that nonnutritive sucking during heelstick procedures may attenuate behavioral distress in all neonates and physiologic arousal in neonates with less severe postnatal complications.
