Cross-cultural perception of female facial appearance: A multi-ethnic and multi-centre study
<p>Humans extract and use information from the face in assessments of physical appearance. Previous research indicates high agreement about facial attractiveness within and between cultures. However, the use of a narrow age range for facial stimuli, limitations due to unidirectional cross-cultural comparisons, and technical challenges have prevented definitive conclusions about the universality of face perception. In the present study, we imaged the faces of women aged 20 to 69 years in five locations (China, France, India, Japan, and South Africa) and secured age, attractiveness, and health assessments on continuous scales (0-100) from female and male raters (20-66 years) within and across ethnicity. In total, 180 images (36 of each ethnicity) were assessed by 600 raters (120 of each ethnicity), recruited in study centres in the five locations. Linear mixed model analysis revealed main and interaction effects of assessor ethnicity, assessor gender, and photographed participant ("face") ethnicity on age, attractiveness, and health assessments. Thus, differences in judgments of female facial appearance depend on the ethnicity of the photographed person, the ethnicity of the assessor, and whether the assessor is female or male. Facial age <a name="_Hlk48726743">assessments </a>correlated negatively with attractiveness and health assessments. Collectively, these findings provide evidence of cross-cultural variation in assessments of age, and even more of attractiveness, and health, indicating plasticity in perception of female facial appearance across cultures, although the decline in attractiveness and health assessments with age is universally found.</p>
Data from: Lower carotid revascularization rates after stroke in ethnic minority-serving US hospitals
Objective: We sought to determine whether the use of carotid revascularization procedures after stroke due to carotid stenosis differs between minority-serving hospitals and hospitals serving predominantly white patients. Methods: We identified ischemic stroke cases due to carotid disease, identified by ICD9-CM codes, from 2007-2011 in the Nationwide Inpatient Sample. The use of carotid endarterectomy (CEA) and carotid artery stenting (CAS) was recorded. Hospitals with ≥40% ethnic minority patients (minority-serving hospitals) were compared to hospitals with <40% minority patients (white hospitals). Logistic regression was used to evaluate the use of CEA/CAS among minority-serving and white hospitals. Results: Of the 26,189 ischemic stroke cases meeting inclusion criteria, 20,870 (79.7%) were treated at 1,113 white hospitals, and 5,319 (20.3%) received care at 325 hospitals minority-serving hospitals. Compared to patients in white hospitals, patients in minority hospitals were less likely to undergo CEA/CAS (17.6%, 95% CI 16.6%-18.6%, in minority vs. 21.2%, 95% CI 20.7%-21.8%, in white hospitals, p<0.001). In fully adjusted logistic regression models, the odds of CEA/CAS were lower in minority compared to white hospitals (OR 0.81, 95% CI 0.70-0.93), independent of individual patient race and other measured hospital characteristics. Whites and Hispanics had significantly lower odds of CEA/CAS in minority compared to white hospitals. Patient-level racial differences in the use of carotid revascularization procedures remained within each hospital stratum. Conclusions: The odds of carotid revascularization after stroke is lower in minority-serving compared to white hospitals, suggesting system-level factors as a major contributor to explain race disparities in the use of carotid revascularization.
Data from: The effect of CAG repeats length on differences in hirsutism among healthy Israeli women of different ethnicities
Purpose: Variations in the degree of hirsutism among women of different ethnic backgrounds may stem from multiple etiologies. Shorter length of the polymorphic CAG repeats of the androgen receptor (AR) gene may be associated with increased activity of the receptor leading to hirsutism. We hypothesized that there are ethnic differences in the degree of hirsutism that is unrelated to androgen levels among Israeli women, and that the CAG repeats length may contribute to these differences. Anti-androgenic therapies, such as spironolactone, could be suggested if a shorter CAG repeats length is found to affect the difference in the degree of hirsutism between the ethnic groups. Methods: Healthy Israeli Jewish women aged 18-45 years of Ashkenazi and non-Ashkenazi origin were invited to participate. Hirsutism was assessed using the simplified Ferriman-Gallwey (sFG) score, and serum total testosterone levels were measured as well. The CAG repeats length was determined by PCR. Methylation-sensitive methods were used to detect the fractional activity of each allele, and the weighted mean was calculated for the CAG repeats length. Results: One-hundred and eight women were recruited (49 Ashkenazi and 59 non-Ashkenazi). The Ashkenazi women had a significantly lower degree of hirsutism (P<0.01), lower mean BMI (P=0.003), total testosterone levels (P=0.017), and longer weighted bi-allelic CAG repeats mean (P=0.015) compared to non-Ashkenazi women. For the group as a whole, there was a significant negative correlation between the number of CAG repeats in the AR gene and the sFG score, while the number of repeats was not related to testosterone levels. Stepwise logistic regression revealed that ethnic origin and the CAG repeats length were the strongest factors affecting hirsutism (P<0.001, P=0.03, respectively). Conclusions: There is a significant difference in the degree of hirsutism between Ashkenazi and non-Ashkenazi women in Israel that is partially explained by CAG repeats length.

Data from: Contribution of Asian haplotype of KCNJ18 to susceptibility to and ethnic differences in thyrotoxic periodic paralysis
Context and Objectives: Thyrotoxic periodic paralysis (TPP) is an acute complication of thyrotoxicosis that can be lethal. TPP is relatively rare in Caucasians but often affects young males in East Asian populations. This study aimed to clarify the contribution of KCNJ18 to susceptibility to TPP in East Asian populations. Participants and Methods: The study comprised 635 participants including 13 Japanese patients with TPP, 208 Japanese patients with Graves' disease without TPP, and 414 healthy control subjects from the Japanese [n=208], Korean [n=111], and Caucasian populations [n=95]. DNA samples from 29 subjects (13 with TPP, 8 with Graves' disease, and 8 controls) were sequenced for KCNJ18, and all subjects (n=635) were genotyped for six variants of KCNJ18 and a polymorphism of KCNJ2 (rs312691). Results: Six single nucleotide variants (SNVs) with amino acid substitutions were identified by direct sequencing of KCNJ18. Among these, four SNVs comprised three haplotypes under strong linkage disequilibrium. Haplotype 1 (AAAG) of KCNJ18 was significantly associated with susceptibility to TPP in the Japanese population (odds ratio [95%CI]: 19.6 [1.5–256.9], p=0.013). Haplotype frequencies in the general East Asian (Japanese and Korean) and Caucasian populations differed significantly (Haplotype 1: 80.8% vs. 48.4%, p= 1.1×10-27). Conclusion: A major haplotype of KCNJ18 in East Asian populations is significantly associated with susceptibility to thyrotoxic periodic paralysis. The haplotype is much more frequent in East Asian than Caucasian populations, suggesting its contribution to the high prevalence of TPP in East Asian populations.
