Although early diagnosis and treatment are key factors in the effective control of human African trypanosomiasis (HAT), many cases of the disease delay taking appropriate action, leading to untold suffering. As a better understanding of treatment-seeking behaviour should help in identifying the obstacles to early diagnosis and effective treatment, the treatment pathways followed by 203 former H...

OBJECTIVES To examine ethnic differences in pain sensitivity and relationship of pain tolerance to blood pressure and neuroendocrine factors. METHODS Fifty-one African Americans (24 men, 27 women) and 55 people from other ethnic groups (primarily Caucasian; 26 men, 29 women) were tested twice for pain sensitivity to tourniquet ischemia, thermal heat, and cold pressor tests, once following men...

African horse sickness (AHS) is a severe, often fatal, arbovirus infection of horses, transmitted by Culicoides spp. midges. AHS occurs in most of sub-Saharan Africa and is a significant impediment to export of live horses from infected countries, such as South Africa. A stochastic risk model was developed to estimate the probability of exporting an undetected AHS-infected horse through a vecto...

BACKGROUND Increasing numbers of human African trypanosomiasis (HAT) cases have been reported in urban residents of Kinshasa, Democratic Republic Congo since 1996. We set up a case-control study to identify risk factors for the disease. METHODS All residents of the urban part of Kinshasa with parasitologically confirmed HAT and presenting for treatment to the city's specialized HAT clinics be...

BACKGROUND Individuals at greater risk for cardiovascular disease (CVD) display poorer cognitive functioning across various cognitive domains. This finding is particularly prevalent among older adults; however, few studies examine these relationships among younger adults or among African Americans. PURPOSE The objective was to examine the relationships among 2 cardiovascular risk factors, ele...

The personal/group discrimination discrepancy involves disadvantaged group members rating discrimination directed at their group considerably higher than ratings of discrimination aimed at themselves personally as members of that group. This robust phenomenon has been found in samples of women, African Americans, and aboriginal people. In the present study, the authors used a sample of Inuit fr...

tom. He can neither sit still, nor concentrate, nor do any one thing for even a short space of time?a much shorter space than the word concentration implies. His mother insists his trouble is due to a fall. She adds the fact that about the time of the fall he had a touch of sleeping sickness. No final diagnosis has yet been made, but, on the basis of probabilities, the fall has most likely had ...

The authors wish to make the following changes to their paper [...].

The present study examined differences in cognitive performance of African American and European American older adults on cognitive and intellectual measures, and the extent to which literacy status or reading level was useful in explaining these group differences. African American elders performed more poorly than European American elders on 12 of 13 cognitive tests administered, p < .05. Afte...

Six studies investigated the extent to which American ethnic groups (African, Asian, and White) are associated with the category "American." Although strong explicit commitments to egalitarian principles were expressed in Study 1, Studies 2-6 consistently revealed that both African and Asian Americans as groups are less associated with the national category "American" than are White Americans. ...
