Q: Abstract: Half-hourly sampling of plasma TSH was done across 3 days in four normal young men. Sleep was denied for 64 h from 0700 h on awakening from accommodation sleep until polygraphic sleep was resumed at 7100 h of the third day (D3) such that 2 consecutive nights of usual 2300-0700 h sleep were missed. This protocol allowed examination of any modulatory effects on the daily patterns in TSH concentrations during sleep deprivation on D1-2 (1100-3500, 3500-5900 h) or during resumption of usual nightly sleep on D3 (5900-8300) compared to that of a previously studied group of normal young men. The circadian nature of the daily TSH waveform was evidenced by its daily repetition within a subject both basally and during D1-2 sleep deprivation and by its synchronization within the basal, deprived, or resumed sleep days. The peaks in each subject's daily TSH patterns on D1-2 were consistently longer, and the daily maxima and cosine acrophases on D1-2 were consistently later than those on D3 when basal sleep was resumed. About half the daily TSH concentration maxima and daily cosinor amplitudes on D1-2 were greater than those of the respective sleep-resumed TSH patterns of D3. Both the group mean TSH patterns and the cosinor 95% confidence ellipses also indicated the daily peak in the TSH waveform to be significantly longer, later, and larger during D1-2 sleep deprivation than during the basal or D3 periods. These results indicate that significant alteration of the daily TSH waveform can occur in response to absence of sleep and are compatible with the existence of an inhibitory effect in early nightly sleep on TSH release. The TSH patterns during the 1700-2300 h intervals of rising TSH levels were congruent in the basal, deprived, and resumed sleep periods. Prompt reversion to the basal TSH pattern also occurred when sleep was resumed on D3. Both of these observations suggest the alteration in TSH waveform during sleep deprivation to have arisen from an inhibitory effect in sleep rather than from a change in period or phase of a generating oscillator.

Q: Abstract: To determine if constituents of cotton plants might play a role in byssinosis by injuring pulmonary epithelium, we added extracts of cotton dust, green bract, and field-dried bract to human A549 and rat type II pneumocytes. Injury was measured as pneumocyte lysis and detachment, and inhibition of protein synthesis. Extracts of cotton dust and field-dried bract produced significant dose- and time-dependent lysis and detachment of both target cells, while green bract extract was less damaging. Extracts treated with polyvinylpolypyrrolidone to remove tannins produced significantly less injury. In contrast, purified 5,7,3',4'-tetrahydroxy-flavan 3,4-diol (THF), a tannin in cotton dust and bract, caused substantial cell damage. Field-dried bract extract and THF also produced dose-dependent inhibition of pneumocyte protein synthesis. Endotoxin levels did not correlate with observed injury. THF added to rat tracheal explants caused epithelial disruption and desquamation, whereas endotoxin did not. Instillation of cotton dust and field-dried bract extract in rat lungs produced disruption of bronchial epithelium and smooth muscle constriction, while polyvinylpolypyrrolidone-treated cotton dust extract produced no injury. These findings suggest that extracts of cotton plants are toxic to alveolar, tracheal, and bronchial epithelium and that THF or other tannins may be the responsible agents.

Q: Abstract: We hypothesize that the respiratory and functional states of the very low birth weight infant with bronchopulmonary dysplasia can be improved in the neonatal intensive care unit by prevention of inappropriate sensory input. To test this hypothesis, we developed for preterm newborns a behavior observation method that catalogues specific reaction patterns according to putative stress and relaxation behaviors. We then collected behavioral information and heart rate, respiratory rate, and transcutaneous PO2 readings before, during, and after routine care-giving interventions. Eight control and eight experimental infants were selected for study based on the following criteria: birth weight less than 1,250 g, gestational age less than 28 weeks, on the respirator greater than 24 hours in first 48 hours of life at greater than or equal to 0.60 FiO2 for more than two hours during first 48 hours of life. Additionally, the two groups were comparable on other medical and demographic variables, including severity of respiratory status for the first ten days and incidence of intraventricular hemorrhage, patent ductus arteriosus, and socioeconomic status. Systematic observations were conducted on days 10, 20, and 30 after birth and at 36 and 40 weeks postconception. For the intervention infants, our observations were discussed with the infants' primary nurses, and individualized modifications for each infant's care plan were implemented based on these observations. Experimental infants showed significantly briefer stays on the respirator (P less than .01) and in increased FiO2 (P less than .05). Their feeding behavior was normalized significantly earlier (P less than .01). Experimental infants also showed significantly better behavioral regulation scores at 1 month after their mothers' estimated dates of confinement (post-EDC), as measured with the Assessment of Preterm Infants' Behavior, significantly better Mental and Psychomotor Developmental Indices at 3, 6, and 9 months post-EDC, as measured with the Bayley Scales of Infant Development, and significantly better behavioral regulation scores at 9 months post-EDC, as measured in a videotaped play observation. Measurements of weight, height, and head circumference at 3, 6, and 9 months post-EDC showed no differences. All assessments were performed by one of two trained testers not familiar with the goals of the study or the group status of the infant. These results support the hypothesis that very low birth weight preterm babies profit significantly both medically and developmentally from individualized behavioral care in the neonatal intensive care unit.
