Deafness is known to affect processing of visual motion and information in the visual periphery, as well as the neural substrates for these domains. This study was designed to characterize the effects of early deafness and lifelong sign language use on visual category sensitivity of the N170 event-related potential. Images from nine categories of visual forms including upright faces, inverted faces, and hands were presented to twelve typically hearing adults and twelve adult congenitally deaf signers. Classic N170 category sensitivity was observed in both participant groups, whereby faces elicited larger amplitudes than all other visual categories, and inverted faces elicited larger amplitudes and slower latencies than upright faces...

BACKGROUND: American Indian and Alaska Native (AI/AN) breast cancer survivors experience disparities in breast cancer incidence and age-adjusted mortality compared with non-Hispanic white (NHW) breast cancer survivors. In addition, mortality-to-incidence rates indicate that AI/ANs continue to have the poorest survival from breast cancer compared with other racial groups. "Native American Cancer Education for Survivors" (NACES) is a cultural education and support intervention for AI/AN patients with cancer that collects data from voluntary participants through the NACES quality-of-life (QOL) survey regarding their cancer experience and survivor journey...

INTRODUCTION: Cancer is among the leading causes of death in American Indians and Alaska Natives (AI/ANs), with rates increasing over the last two decades. Barriers in accessing cancer screening and treatment likely contribute to this situation. METHODS: We administered structured clinical interviews and conducted descriptive and multiple linear regression analyses of demographic, health, spiritual, and treatment factors associated with self-reported barriers to cancer care among 143 adult AI/AN oncology patients...

: American Indians and Alaska Natives (AI/AN) experience significant health disparities relative to the general U.S. POPULATION: In particular, oral diseases affect the majority of the AI/AN population and their prevalence is significantly greater than observed in other demographic sectors of the U.S. POPULATION: The reasons for these disparities are multiple but lack of access to dental care is clearly a contributing factor. The dentist-to-population ratio in many AI/AN communities is less than half the U...

OBJECTIVES: Quilombo remnants are relics of communities founded by runaway or abandoned African slaves, but often with subsequent extensive and complex admixture patterns with European and Native Americans. We combine a genetic study of Y-chromosome markers with anthropological surveys in order to obtain a portrait of quilombo structure and history in the region that has the largest number of quilombo remnants in the state of São Paulo. METHODS: Samples from 289 individuals from quilombo remnants were genotyped using a set of 17 microsatellites on the Y chromosome (AmpFlSTR-Yfiler)...

This paper examined the prevalence of depressive symptomotology among women of Mexican ancestry (N = 205), over the age of 18, of diverse incomes and nativity. We examined differences in rates of diagnosis by Spanish/English preference and the sensitivity and specificity of three common measures: the Patient Health Questionnaire (PHQ9), the Kessler Psychological Distress Scale (K-10), and depression questions from the Composite International Diagnostic Interview, Short Form (MDD CIDI-SF); PHQ9 was used as the "gold standard" measure...

Despite evidence of the benefits of preconception health care (PCHC), little is known about awareness and access to PCHC for rural, reproductive-aged women. This study aimed to assess the prevalence of PCHC conversations between rural reproductive-age women and health care providers, PCHC interventions received in the past year, and ascertain predictors of PCHC conversations and interventions. Women (n = 868; 18-45 years) completed a questionnaire including reproductive history, health care services utilization, and interest in PCHC...

Cardiovascular diseases (CVD) are major causes of death and illness worldwide. In recent decades an increased prevalence of CVD mortality has been reported in low-medium income countries, which has been associated with changes in life styles, deficiencies in health systems and the persistence of social inequities.The metabolic syndrome comprises a cluster of cardiometabolic risk factors, with insulin resistance and increased adiposity as its central features. Identifying individuals with metabolic syndrome is important due to its association with an increased risk of coronary heart disease and type 2 diabetes mellitus (DM2)...

BACKGROUND: Representing 2 % of the general population, American Indians/Alaska Natives (AIs/ANs) were associated with 0.5 % (63) of the estimated 12,500 new cases of spinal cord injury (SCI) reported to the National Spinal Cord Injury Statistic Center in 2013. To date, the trend in health care disparities among AIs/ANs in the SCI community has not been examined. We sought to compare the rate of discharge to rehabilitation facilities (DRF) following traumatic SCI among adult AIs/ANs to other racial/ethnic groups for patients 15 to 64 years old...

This study represents a preliminary effort to examine the possible impacts of chronic, low level Domoic Acid (DA) exposure on memory in the CoASTAL cohort. Five hundred thirteen men and women representing three Native American Tribes were studied with standard measures of cognition and razor clam consumption (a known vector of DA exposure) over a four year period. In addition, a pilot metric of DA concentration exposure was used which took into consideration average DA concentration levels in source beaches as well as consumption...

The eastern cherry fruit fly, Rhagoletis cingulata Loew (Diptera: Tephritidae), is an economically important pest of cherries in North America. In 1983 it was first reported in Europe where it shares its ecological niche with the native European cherry fruit fly, Rhagoletis cerasi L. (Diptera: Tephritidae). Their coexistence in Europe led to the recent horizontal transmission of the Wolbachia strain wCer1 from R. cerasi to R. cingulata Horizontal Wolbachia transmission is mediated by either sharing of ecological niches or by interacting species such as parasitoids...

The human head louse, Pediculus humanus capitis, is subdivided into several significantly divergent mitochondrial haplogroups, each with particular geographical distributions. Historically, they are among the oldest human parasites, representing an excellent marker for tracking older events in human evolutionary history. In this study, ancient DNA analysis using real-time polymerase chain reaction (qPCR), combined with conventional PCR, was applied to the remains of twenty-four ancient head lice and their eggs from the Roman period which were recovered from Israel...
