Two-syllable words (burden; furrow; mantle; ration) each spoken in happy, angry, sad, and neutral tones of voice were dichotically paired. For each presented word-pair, subjects were asked to localise ("left"; "right") or reject the presence of one pre-specified word on one block of trials and one pre-specified emotional tone on a second trial block. Right ear advantages (REAs) indicated by a superior hit rate averaging 9.6% were found for all words. Left ear advantages (LEAs) averaging 15.2% were obtained for emotional intonation, with additional evidence of differences between emotion categories. Results are discussed in terms of complementary hemispheric roles for linguistic and prosodic analysis.  相似文献

CONTEXT: Since the beginning of the North Atlantic Treaty Organization intervention in Kosovo in June 1999, few objective data have been available on relevant health indicators for the Serbian ethnic minority in Kosovo. OBJECTIVE: To determine the prevalence of undernutrition among Serbian adults aged 60 years or older and psychiatric morbidity among the adult Serbian population in Kosovo. DESIGN, SETTING, AND PARTICIPANTS: A systematic random sample survey of 212 households was conducted between September 27 and October 2, 1999, in Pristina, the capital city, and in 10 towns in the rural municipality of Gnjilane in Kosovo. Of the 212 households surveyed, 204 adults aged 15 years or older completed the General Health Questionnaire-28 (GHQ-28) and anthropometric measurements were taken for 98 adults aged 60 years or older and for a comparison group of 51 adults aged 18 to 59 years. MAIN OUTCOME MEASURES: Body mass index of less than 18.5 kg/m(2) in older adults; nonspecific psychiatric morbidity among adults; and self-reported use of health care services, access to food rations, and primary sources of prewar and postwar income. RESULTS: Undernutrition was found in 11.2% (95% confidence interval [CI], 5.7%-19.2%) of Serbian adults aged 60 years or older compared with 2.0% (95% CI, 0.1%-11.8%) of Serbian adults aged 18 to 59 years. The mean (SE) total score for the GHQ-28 was 13.0 (0.52). In a comparison of the GHQ-28 scores of the Serbian adults with the Kosovar Albanian adults (data from a recent survey), the mean (SE) score adjusted for age and sex was 12.8 (0.52) vs 11.1 (0.58); P =.03, respectively. The GHQ-28 scores were also higher for the Serbians in the subcategories of social dysfunction (2.8 [0.17] vs 2.2 [0.13]; P =.008) and severe depression (1.9 [0.15] vs 0.9 [0. 09]; P<.001), respectively. Serbian women and persons living alone or in small family units were more prone to psychiatric morbidity. Of the 141 respondents reporting the need for health care services, 83 (57.6%) reported not obtaining such services; 204 of 212 (96.2%) households were on a food distribution list. The majority of prewar income came from government jobs compared with farming and humanitarian aid for postwar income. CONCLUSIONS: The undernutrition of older Serbian adults in Kosovo should be monitored. The high prevalence of symptoms of social dysfunction and severe depression suggest the need for implementation of mental health programs in the Serbian community. JAMA. 2000;284:578-584  相似文献

AIM—To define the origin and the natural history of innocent heart murmurs in newborn infants.METHODS—Fifty healthy babies born at term with the clinical diagnosis of an innocent heart murmur and 50 controls without a murmur were studied. Each baby had a complete two dimensional and pulsed Doppler echocardiogram and those with any abnormality were followed up at 6 weeks, 3 months, and 6 months until the murmur had disappeared or the heart was totally normal. Babies with congenital heart disease were excluded from the study.RESULTS—Pulmonary branch stenosis (PBS) was found in 25 (50%) of the study group and in six (12%) controls; patent ductus arteriosus (PDA) in 30 (60%) subjects and in six (12%) controls; and a patent foramen ovale (PFO) in 50 (100%) subjects and in 41 (82%) controls. At 6 weeks the murmur had disappeared in 64% of babies. PBS was still present in eight of 22 (36%) babies at 6 weeks, in 12% at 3 months, but in none at 6 months. At 6 weeks, seven of the eight with PBS still had a murmur compared with two of 14 (14%) babies in which the PBS had resolved (P<0.005). At 6 weeks the PDA had closed in all patients but the foramen ovale was still patent in 29 of 44 (66%) subjects and nine of 33 (27%) controls. The closure of the PFO was not influenced by its size at birth.CONCLUSIONS—An innocent heart murmur in a baby born at term is often related to PBS, particularly if the murmur is still present after 24 hours of age, when most PDA have closed. At 6 weeks the murmur had disappeared and the PBS had resolved in 64% of the babies. PBS had resolved in all babies at 6months.  相似文献

Based on 20,713 singleton livebirths at the John Radcliffe Hospital, Oxford, in 1978-1984, we calculated new birthweight and head circumference values for males and females between 24 and 42 weeks of gestation. Among the 803 babies born at or before 34 weeks of gestation, 28% were delivered electively for fetal problems; they were considerably lighter and had smaller heads than infants born after spontaneous preterm labour. As we and others have recommended elsewhere, the electively delivered preterm infants were excluded from the calculation of the new birthweight and head circumference centiles. In our series males were heavier and had larger head circumferences than females at most gestational ages. There were consistent and statistically significant differences in birthweight at all gestational ages from 37 weeks and in head circumference at all gestational ages from 35 weeks.  相似文献
