Can population BRCA screening be applied in non-Ashkenazi Jewish populations? Experience in Macau population.

BACKGROUND: Pathogenic mutation in BRCA genes causes high cancer risk. Identifying the mutation carriers plays key roles in preventing BRCA mutation-related cancer. Population screening has demonstrated its power for comprehensive identification of the mutation carriers. However, it is only recommended for the Ashkenazi Jewish population with high prevalence of three founder mutations, but not for non-Ashkenazi Jewish populations as the cost-effectiveness could be too low due to their lower mutation prevalence and lack of founder mutation. Population screening would not benefit the majority of the human population for BRCA mutation-related cancer prevention. METHODS: We used population BRCA screening in 6000 residents, 1% of the Macau population, an ethnic Chinese population with unique genetic, linguistic and cultural features, and its BRCA mutation has not been analysed before. RESULTS: We called BRCA variants, identified 18 carriers with 14 pathogenic mutations and determined the prevalence of 0.29% in the population (95% CI 0.15% to 0.42%). We compared the testing cost between the Ashkenazi Jewish population, the Sephardi Jewish population and the Macau population, and observed only a few fold differences. CONCLUSION: Our study shows that testing cost is not the most important factor in considering population BRCA screening, at least for the populations in the developed countries/regions, regardless of the status of mutation prevalence and founder mutation.

Risk factors for sebaceous gland diseases and their relationship to gastrointestinal dysfunction in Han adolescents.

Sebaceous gland diseases are a group of common dermatological diseases with multiple causes. To date, a systematic report of the risk factors for sebaceous gland diseases in adolescents has not been published. The aim of this study was to assess the prevalence and risk factors for certain sebaceous gland diseases (seborrhea, seborrheic dermatitis, acne, androgenetic alopecia and rosacea) and their relationship to gastrointestinal dysfunction in adolescents. From August-October, 2002-2005, a questionnaire survey was carried out to obtain epidemiological data about sebaceous gland diseases. Using random cluster sampling, 13 215 Han adolescents aged 12-20 years were recruited from four countries or districts (Macau; Guangzhou, China; Malaysia; and Indonesia). The statistical software SPSS ver. 13.0 was used to analyze the data. The prevalence of seborrhea, seborrheic dermatitis, acne, androgenetic alopecia and rosacea was 28.27%, 10.17%, 51.03%, 1.65% and 0.97%, respectively. Based on multivariate logistic regression analysis, the risk factors for sebaceous gland diseases included: age; duration of local residency; halitosis; gastric reflux; abdominal bloating; constipation; sweet food; spicy food; family history of acne; late night sleeping on a daily basis; excessive axillary, body and facial hair; excessive periareolar hair; and anxiety. There was a statistically significant difference in the prevalence of gastrointestinal symptoms (halitosis; gastric reflux; abdominal bloating; constipation) between patients with and without sebaceous gland diseases (chi(2) = 150.743; P = 0.000). Gastrointestinal dysfunction is an important risk factor for diseases of the sebaceous glands and is correlated with their occurrence and development.

Evaluation of an innovative nursing exchange programme: health counselling skills and cultural awareness.

BACKGROUND: In 2006, a two-week summer exchange programme was conducted for nursing students from 15 institutes and/or universities, including places in Taiwan, Macau, Chinese mainland and Hong Kong. AIM: This paper evaluates a summer exchange programme focusing on nursing students' professional and personal development within the context of learning health counselling skills and studying cultural aspects of the host Region. METHOD: The programme was evaluated using a mixed method of both quantitative and qualitative research design. Three dimensions include students' exchange perspective, professional development and personal development were evaluated at the end of the two-week programme. Data for this evaluation were derived from the results of questionnaires completed by the 64 nursing students enrolled in this programme, and from the analysis of five focus group interviews. FINDINGS: Overall, students (98%) reported that they were very positive about their experiences during the programme, and felt they had gained a greater awareness of effective health counselling skills, of the latest developments in advanced nursing technology within the host School, and of cultural diversity in relation to their personal and professional development. Comparison of sub-total mean scores and standard deviations (mean+/-SD) of the three dimensions among students from Taiwan, Chinese mainland and Hong Kong/Macau, revealing significant differences in the exchange perspective (Taiwan: 18.6+/-1.4; Chinese mainland: 18.8+/-1.4; and Hong Kong/Macau: 16.5+/-1.1) professional development (Taiwan: 18.4+/-1.6; Chinese mainland: 18.2+/-1.5; and Hong Kong/Macau: 16.2+/-2.0) and personal development dimensions (Taiwan: 18.9+/-1.0; Chinese mainland: 18.6+/-1.4; and Hong Kong/Macau: 17.3+/-1.1) among these three places (p<0.001). For paired comparison (post-hoc test), the findings also show that the sub-total mean scores of the students from Taiwan and Chinese mainland were significantly higher than those of students from Hong Kong and Macau in the exchange perspective (Taiwan versus Hong Kong/Macau, p<0.001; Chinese mainland versus Hong Kong/Macau, p<0.001), professional development (Taiwan versus Hong Kong/Macau, p=0.001; Chinese mainland versus Hong Kong/Macau, p<0.001), and personal development (Taiwan versus Hong Kong/Macau, p<0.001; Chinese mainland versus Hong Kong/Macau, p=0.002). CONCLUSION: Although the findings cannot be generalized, the programme evaluation highlights the positive impact on one's exchange perspective and professional and personal development of a culturally integrated exchange programme for nursing students, with emphasis on skill practices and cultural diversity.

Post-migratory experiences of newcomer female youth: self-esteem and identity development.

This study explored the post-migratory experiences of newcomer female youth attending secondary school within a multi-cultural context. Focus groups were held with 10 newcomer female youth, in Toronto, Canada. Data were also collected through focus groups or in-depth interviews with school educators, parents, and school and community health center workers. In addition, the Current Self-Esteem (CSE) instrument was utilized to examine the global self-esteem of youth and the influences on their self-esteem. The average age of youth participants was 17 years old and their average age of immigration to Canada was 13.9 years old. The average score for the CSE was 7.9, which indicated that respondents felt, in general, good about themselves. Among the influences on youth's self-esteem were those related to Self, School, Relationships, Achievements and Lifestyle. The emerging sub-themes of the Self-Concept theme, arising from the qualitative data, consisted of Dynamic Self, Silenced Self, Cultural Identity, Female Role Models, Future Aspirations. The impact of the resettlement process on the self-esteem and identity of newcomer females is considered. It is concluded that in multi-cultural and post-migration societies multi-sectoral and context-specific mental health promotion strategies and policies are needed for youth.
