Despite a remarkable increase in Asian births in the U.S., studies on their birth outcomes have been lacking. We investigated outcomes of births to Asian parents and biracial Asian/White parents in the U.S. From the U.S. birth data (1992–2012), we selected singleton births to Korean, Chinese, Japanese, Filipino, Asian Indian, and Vietnamese. These births were divided into three groups; births to White mother/Asian father, Asian mother/White father, and births to the both ethnic Asian parents. We compared birth outcomes of these 18 subgroups to those of the White mother/White father group. Mean birthweights of births to the Asian parents were significantly lower, ranging 18 g to 295 g less than to the White parents. Compared to the rates of low birthweight (LBW) (4.6%) and preterm birth (PTB) (8.5%) in births to the White parents, births to Filipino parents had the highest rates of LBW (8.0%) and PTB (11.3%), respectively, and births to Korean parents had the lowest rates of both LBW (3.7%) and PTB (5.5%). This pattern of outcomes had changed little with adjustments of maternal sociodemographic and health factors. This observation was similarly noted also in births to the biracial parents, but the impact of paternal or maternal race on birth outcome was different by race/ethnicity. Compared to births to White parents, birth outcomes from the Asian parents or biracial Asian/White parents differed depending on the ethnic origin of Asian parents. The race/ethnicity was the strongest factor for this difference while other parental characteristics hardly explained this difference.

Methazolamide is a carbonic anhydrase inhibitor commonly used for lowering intraocular pressure in glaucoma and other ophthalmologic diseases. Carbonic anhydrase inhibitors are sulfonamide derivatives that are known to cause many adverse side effects, including dermatologic reactions. Recently, Stevens-Johnson syndrome (SJS) associated with methazolamide treatment has been reported in Japanese and Japanese Americans, and it suggested a relationship between genetic background and methazolamide-induced SJS. We report four cases of SJS induced by methazolamide. Methazolamide should be prescribed with caution in patients of Japanese or Korean descent.

OBJECTIVES: Families of ethnic minority persons with dementia often seek help at later stages of the disease. Little is known about the effectiveness of various methods in supporting ethnic minority dementia patients' caregivers. The objective of the study was to identify smartphone and computer usage among family caregivers of dementia patients (i.e., Korean and Vietnamese Americans) to develop dementia-care education programs for them. METHODS: Participants were asked various questions related to their computer or smartphone usage in conjunction with needs-assessment interviews. Flyers were distributed at two ethnic minority community centers in Southern California. Snowball recruitment was also utilized to reach out to the families of dementia patients dwelling in the community. RESULTS: Thirty-five family caregivers, including 20 Vietnamese and 15 Korean individuals, participated in this survey. Thirty participants (30 of 35, 85.7%) were computer users. Among those, 76.7% (23 of 30) reported daily usage and 53% (16 of 30) claimed to use social media. A majority of the participants (31 of 35, 88.6%) reported that they owned smartphones. More than half of smartphone users (18 of 29, 62%) claimed to use social media applications. Many participants claimed that they could not attend in-class education due to caregiving and/or transportation issues. CONCLUSIONS: Most family caregivers of dementia patients use smartphones more often than computers, and more than half of those caregivers communicate with others through social media apps. A smartphone-app-based caregiver intervention may serve as a more effective approach compared to the conventional in-class method. Multiple modalities for the development of caregiver interventions should be considered.

BACKGROUND: There are significant differences in the clincopathologic pattern including the incidence, favor site, and histopathologic type between cutaneous malignant melanomas arising from whites, asians and blacks. These differences might suggest that there is a racial difference in the molecular tumorigenesis mechanism of malignant melanoma. METHODS: To determine the ethnic differences in tumorigenesis of malignant melanoma, we performed loss of heterozygosity (LOH) and sequencing analyses of the p53 gene in cutaneous malignant melanomas arising from 22 white American, 30 Korean and 15 black African patients. RESULTS: The frequency of LOH of the p53 gene is only 12.5% in white American patients, but the frequency is significantly higher in Korean (42.1%) and black African (61.5%) patients. We also detected 17 mutations (nonsense: 1, missense: 16) of the p53 gene in the cutaneous malignant melanomas of Koreans and black Africans, but none in those of white Americans: among the 16 missense mutations, 10 mutations were C:G to T:A transitional mutations. Of these, we also detected one GG (CC) to AA (TT) tandem mutation at the pyrimidine sequence. CONCLUSION: These results strongly suggest that there might be a racial difference in molecular carcinogenesis mechanisms among the cutaneous malignant melanomas occurring in white American, Korean and black African patients. But the role of the p53 genetic alteration in the genesis of melanomas in Korean and black African patients is subject to further evaluation.

The purpose of this study was to determine the recognition of body image and food behavior factors according to the BMI. The subjects of this study were 242 7th grade students resided in San Francisco area. The degree of recognition for self-estimated physique of subjects by gender and by race showed no significant differences by gender but significant differences by race, showing that 20.0% was considered as underweight in Asian and 7.5% was considered as underweight in White students. This showed the same tendency as actual physique status (BMI). Also, the ratio of being recognized as more than overweight was 17.3% in Asian, 23.3% in Hispanic, and 13.4% in White students. In case of female students, the ratio of dieting experience was 63.3%, and 49.3% of White students and 63.3% of Hispanic students experienced dieting. In case of students answered not healthy, their body weight were significantly higher than those answered as healthy, and the BMI was also over 19, showing significant differences. Thus cases that answered as not healthy had greater body weight and BMI. Also it showed that frequent dieting experience is related to higher height and weight. The analysis of food behavior factors perceived by body shape showed that the group perceived itself as overweight consumed more 'fast food' but had low scores in 'vegetables' intake, with frequent intake of 'soda' and tendency to 'overeat'. Also, the tendency for 'balanced life' was significantly lower and for skipping breakfast was significantly higher, suggesting problematic food behavior.

With globalization, international exchange has increased. Accordingly, the necessity for individual identification using genetic polymorphism has also increased. Paternal lineages are distributed differently, and different distribution patterns can be used to predict ancestry. We studied the distribution pattern of different paternal lineages in Korea and compared them with other populations. All 30 SNPs on the Y chromosome were selected for paternal lineage confirmation. Loci that could subclassify haplogroup O, the most frequent in the East Asian population, were added. After multiplex amplification for the target loci, SBE reactions were set up for each SNP site. One hundred Korean men as well as 60 Chinese, 60 Japanese, 19 African-American, 48 Caucasian, and 47 Mexican American were tested and compared. Five Y haplogroups [C (C3), D (D2), NO, O, Q (Q1a1)] were found in Koreans, with haplogroup O being the most frequent. Haplogroup O sub-classified into O* (24%), O1 (6%), O2b (39%), O3a3c (4%), O3a3c1 (13%), and O3a3b(1%). This distribution pattern was similar to that of Chinese or Japanese, but minor differences were noted. With Fst, the Korean and Japanese patterns were close (0.01757) when using 6 SNPs. There were significant differences between Koreans and African Americans, Caucasians and Mexican Americans, and they were easily discernible without requiring haplogroup O sub-classification. Sub-classification of haplogroup O is likely to be useful for East Asia group comparisons. Additional studies in populations from different areas of China or Japan or studies of mtDNA or autosomes may enhance the discrimatory power of genetic polymorphism in different Asian populations.

BACKGROUND/OBJECTIVES: Setting healthful beverage expectations, making calcium-rich foods and beverages (CRF/B) available, and role modeling are parenting practices promoting calcium intake among early adolescents. This study aimed to evaluate emotion-based messages designed to motivate parents of early adolescents to perform these practices. SUBJECTS/METHODS: Emotion-based messages were developed for each parenting practice and tested in 35 parents from 5 states. Findings were used to modify messages and develop a survey administered via Amazon MechanicalTurk to a convenience sample of Asian (n = 166) and Hispanic (n = 184) parents of children 10-13 years. Main outcome measures were message comprehension, motivation, relevance, acceptability, and novelty. Engagement in the parenting practices was also assessed. RESULTS: Message comprehension was acceptable for the majority of parents. Most also agreed that messages were motivational (setting healthful beverage expectations (69.0%), making CRF/B available (67.4%), and role modeling (80.0%)), relevant and acceptable. About 30-50% indicated they had not seen the information before. Many parents indicated they were already engaging in the practices (> 70%). No racial/ethnic differences were observed for responses to messages or engaging in parenting practices. CONCLUSIONS: Results indicate that emotion-based messages designed to motivate parents to engage in parenting practices that promote calcium intake among early adolescents were motivating, relevant, and acceptable.

Intracranial atherosclerosis is one of the leading causes of ischemic stroke and occurs more commonly in patients of Asian, African or Hispanic origin than in Caucasians. Although the histopathology of intracranial atherosclerotic disease resembles extracranial atherosclerosis, there are some notable differences in the onset and severity of atherosclerosis. Current understanding of intracranial atherosclerotic disease has been advanced by the high-resolution magnetic resonance imaging (HRMRI), a novel emerging imaging technique that can directly visualize the vessel wall pathology. However, the pathological validation of HRMRI signal characteristics remains a key step to depict the plaque components and vulnerability in intracranial atherosclerotic lesions. The purpose of this review is to describe the histological features of intracranial atherosclerosis and to state current evidences regarding the validation of MR vessel wall imaging with histopathology.
