Do changes in pattern of breast usage alter the baby's nutrient intake?

Twelve mother/baby pairs took part in a study of the difference in effect of two patterns of breast feeding--either feeding at one breast or at two breasts during a feed. Baseline measures were taken at 4 weeks, and the test patterns of feeding were followed for a week each, in random order. The two patterns of feeding led to differences in milk volume intake and mean feed fat concentration, but not in the baby's net fat intake per 24 h. The results indicate that the breast-fed baby can regulate his fat intake quickly and thus mothers should be encouraged to practice "baby-led" feeding.

Automatic and volitional semantic processing in aphasia.

The present study investigated the status of semantic information in aphasia by comparing the performances of aphasic and nonaphasic subjects on two tasks: an automatic semantic facilitation task and a volitional task of relatedness judgment. Both the aphasic and nonaphasic groups evidenced a semantic facilitation effect, in an on-line task of semantic processing. However, those aphasics with severe comprehension and naming disturbances (termed low comprehension aphasics) demonstrated considerable difficulty in judging the relatedness between a pictured object and members of that object's semantic field, the severity of the impairment being greater for those pictures that the low comprehension aphasics were unable to name. The pattern of results can best be explained by supposing the structural integrity of the store of semantic information in aphasia, and in particular in low comprehension aphasia: information that is retrieved and manipulated in judgment-mediated tasks with considerable difficulty.

Respiratory function in Parkinson's subjects exhibiting a perceptible speech deficit: a kinematic and spirometric analysis.

The respiratory abilities of a group of 19 speech-disordered subjects with idiopathic Parkinson's disease were assessed using both spirometric and kinematic techniques and compared to those of a group of 19 nonneurologically impaired controls matched for age and sex. Results of the spirometric assessment showed that only a minority of the Parkinson's subjects had lung volumes and capacities outside normal limits. Consequently in the majority of cases, the speech disorder could not be related to any abnormality in lung function determined spirometrically. Chest wall dynamics during both conversation and reading were essentially normal in all cases. Approximately half of the Parkinson's subjects, however, exhibited irregularities in their chest wall movements while performing vowel prolongation and syllable repetition tasks. The same irregularities were not present in the chest wall movements exhibited by the control subjects, suggesting that their presence was in some way related to the Parkinson's disease. Results are discussed in terms of the effects of Parkinson's disease on neuromuscular function.
