Parental decision about human papillomavirus vaccination for their daughters

Background: Human papillomavirus (HPV) infection is a sexually transmitted infection common in teenagers and adults in their early 20s. Some types of HPV are associated with 90% of cervical cancer around the world. The risk of HPV infection in women can be reduced by giving HPV vaccine to girls beginning at the age of 9, as recommended by Centers for Disease Control and Prevention (CDC). For children and young adolescents, parental decision on HPV vaccination is crucial for the uptake of HPV vaccine rate. This study explored the factors influencing parental decisions on HPV vaccination for their daughters. Methods: A cross-sectional survey was conducted between February and March 2017. Data were collected from parents of girls aged 9 to 17 (n=420, 100 % response rate) in Hong Kong. A validated 27-item questionnaire was used to elicit parents’ knowledge on HPV and HPV vaccine, barriers to HPV vaccination, and willingness toward vaccinating their daughter(s). Results: Only 59.6% of respondents were aware of the HPV vaccine before this study. Among the parents who were aware of the vaccine, around 32% had already vaccinated their daughters. Majority (83%) of the parents had heard of HPV, but the knowledge levels were poor (70% scored below average). The reasons parents did not vaccinate their daughters were fear of the side-effects of the vaccine (85.7%) and feared the vaccine would affect the immune system of their daughters (38.5%); around 18% believed that HPV vaccination would encourage early sexual activity or promiscuity. More than half of the respondents (69.7%) were willing to vaccine their daughter(s). Conclusions: Given the evidence of suboptimal awareness about HPV vaccination, education and promotional strategies should be enhanced. Interventions should address parental concerns about the misconceptions between vaccination and early sexual activity and promiscuity

A survey: Knowledge about breast cancer and health beliefs towards screening practice among menopausal and postmenopausal women

Breast cancer is a major health problem with high mortality in women worldwide and has become the third most prevalent disease among women in Hong Kong. Knowledge about breast cancer is closely related to health beliefs towards screening practices for breast cancer. This study examined knowledge about breast cancer and breast cancer screening (BCS) beliefs among menopausal and postmenopausal women. A total of 213 eligible women, mostly aged 55 to 60, who were housewives or retired and were educated at secondary school level or above, were selected. A survey using the Chinese Breast Cancer Screening Beliefs (CBCSB) questionnaire was conducted. The results revealed that menopausal and postmenopausal women had better health beliefs towards breast cancer screening practices. Education was found to be positively associated with attitudes of BCS health beliefs. It indicates that education can affect attitudes towards breast cancer screening practice. Most of the women presented inadequate knowledge and they wished to receive more information about breast cancer although they were well-educated. It is important to note that knowledge about breast cancer cannot be effectively delivered to the at-risk women. In addition, menopausal and postmenopausal women can be more likely to seek more information about the effectiveness and side effects of the medication for breast cancer. Therefore, treatment about effectiveness, side effects, and prices ought to be included in current educational programs and healthcare services in the promotion schemes. Healthcare professionals should also pay more attention to better BCS practices in community-based educational programs with information on preventive measures for breast cancer to menopausal and postmenopausal women, particularly to those in lower socioeconomic classes

A survey of the perceived lifestyle risks of breast cancer in menopausal and postmenopausal women in Hong Kong

Breast cancer ranks as the most common cause of cancer death in women. If menopausal and postmenopausal women know the lifestyle risks associated with breast cancer and its preventive measures, they will make appropriate choices in order to enjoy their life and have a better chance of preventing this disease. This study attempted to explore perceived beliefs with regard to the lifestyle risks associated with breast cancer among menopausal and postmenopausal women in Hong Kong. A survey was designed that used a self-reporting questionnaire to assess the perceived beliefs of 223 women. Results showed that more than half of the participants held misconceptions about lifestyle breast cancer risks. Only those women who were well-educated and were worried about having breast cancer performed breast screening for cancer. The findings of this study suggest that health care professionals should channel resources to educate menopausal and postmenopausal women about the risks of breast cancer and to promote awareness of breast wellness and the value of breast cancer screening

Menopausal-specific quality of life among women in Hong Kong

This study aimed to explore the menopausal-specific quality of life and assess its relationship with the sociodemographic characteristics in menopausal and post-menopausal women in Hong Kong. A cross-sectional survey was conducted with 218 women aged between 45 and 80 or over. The quality of life was assessed by Menopause-Specific Quality of Life Questionnaire (MENQOLTM). Results showed that the mean scores for vasomotor domain: 2.59 ± 1.71; psycho-social domain: 2.77 ± 1.39; physical domain: 2.89 ± 1.23 and sexual domain 2.60 ± 1.16. The physical domain had the highest score in menopausal and post-menopausal women. Univariate analysis demonstrated that younger and less educated working post-menopausal women perceive lower quality of life. Our findings suggest that menopausal-related symptoms affect the quality of life

Can non-interactive language input benefit young second-language learners?

To fully acquire a language, especially its phonology, children need linguistic input from native speakers early on. When interaction with native speakers is not always possible – e.g. for children learning a second language that is not the societal language – audios are commonly used as an affordable substitute. But does such non-interactive input work? Two experiments evaluated the usefulness of audio storybooks in acquiring a more native-like second-language accent. Young children, first- and second-graders in Hong Kong whose native language was Cantonese Chinese, were given take-home listening assignments in a second language, either English or Putonghua Chinese. Accent ratings of the children's story reading revealed measurable benefits of non-interactive input from native speakers. The benefits were far more robust for Putonghua than English. Implications for second-language accent acquisition are discussed.postprin

Scallop swimming kinematics and muscle performance: modelling the effects of "within-animal" variation in temperature sensitivity

Escape behaviour was investigated in Queen scallops (Aequipecten opercularis) acclimated to 5, 10 or 15 degrees C and tested at their acclimation temperature. Scallops are active molluscs, able to escape from predators by jet-propelled swimming using a striated muscle working in opposition to an elastic hinge ligament. The first cycle of the escape response was recorded using high-speed video ( 250 Hz) and whole-animal velocity and acceleration determined. Muscle shortening velocity, force and power output were calculated using measurements of valve movement and jet area, and a simple biomechanical model. The average shortening speed of the adductor muscle had a Q(10) of 2.04, significantly reducing the duration of the jetting phase of the cycle with increased temperature. Muscle lengthening velocity and the overall duration of the clap cycle were changed little over the range 5 - 15 degrees C, as these parameters were controlled by the relatively temperature-insensitive, hinge ligament. Improvements in the average power output of the adductor muscle over the first clap cycle ( 222 vs. 139 W kg(-1) wet mass at 15 and 5 degrees C respectively) were not translated into proportional increases in overall swimming velocity, which was only 32% higher at 15 degrees C ( 0.37m s(-1)) than 5 degrees C (0.28 m s(-1))

Hablamos Juntos (Together We Speak): Interpreters, Provider Communication, and Satisfaction with Care

The Hablamos Juntos—Together We Speak (HJ)—national demonstration project targeted the improvement of language access for Spanish-speaking Latinos in areas with rapidly growing Latino populations. The objective of HJ was to improve doctor-patient communication by increasing access to and quality of interpreter services for Spanish-speaking patients. To investigate how access to interpreters for adult Spanish-speaking Latinos is associated with ratings of doctor/office staff communication and satisfaction with care. Cross-sectional cohort study. A total of 1,590 Spanish-speaking Latino adults from eight sites across the United States who participated in the outpatient HJ evaluation. We analyzed two multi-item measures of doctor communication (4 items) and office staff helpfulness (2 items), and one global item of satisfaction with care by interpreter use. We performed regression analyses to control for patient sociodemographic characteristics, survey year, and clustering at the site of care. Ninety-five percent of participants were born outside the US, 81% were females, and survey response rates ranged from 45% to 85% across sites. In this cohort of Spanish-speaking patients, those who needed and always used interpreters reported better experiences with care than their counterparts who needed but had interpreters unavailable. Patients who always used an interpreter had better adjusted ratings of doctor communication [effect size (ES = 0.51)], office staff helpfulness (ES = 0.37), and satisfaction with care (ES = 0.37) than patients who needed but did not always use an interpreter. Patients who needed and always used interpreters also reported better experiences with care in all three domains measured [doctor communication (ES = 0.30), office staff helpfulness (ES = 0.21), and satisfaction with care (ES = 0.23)] than patients who did not need interpreters. Among adult Spanish-speaking Latinos, interpreter use is independently associated with higher satisfaction with doctor communication, office staff helpfulness, and ambulatory care. Increased attention to the need for effective interpreter services is warranted in areas with rapidly growing Spanish-speaking populations

Electronic Properties of Boron and Nitrogen doped graphene: A first principles study

Effect of doping of graphene either by Boron (B), Nitrogen (N) or co-doped by B and N is studied using density functional theory. Our extensive band structure and density of states calculations indicate that upon doping by N (electron doping), the Dirac point in the graphene band structure shifts below the Fermi level and an energy gap appears at the high symmetric K-point. On the other hand, by B (hole doping), the Dirac point shifts above the Fermi level and a gap appears. Upon co-doping of graphene by B and N, the energy gap between valence and conduction bands appears at Fermi level and the system behaves as narrow gap semiconductor. Obtained results are found to be in well agreement with available experimental findings.Comment: 11 pages, 4 figures, 1 table, submitted to J. Nanopart. Re

(Not so) Great Expectations: Listening to Foreign-Accented Speech Reduces the Brain's Anticipatory Processes.

This study examines the effect of foreign-accented speech on the predictive ability of our brain. Listeners actively anticipate upcoming linguistic information in the speech signal so as to facilitate and reduce processing load. However, it is unclear whether or not listeners also do this when they are exposed to speech from non-native speakers. In the present study, we exposed native Dutch listeners to sentences produced by native and non-native speakers while measuring their brain activity using electroencephalography. We found that listeners' brain activity differed depending on whether they listened to native or non-native speech. However, participants' overall performance as measured by word recall rate was unaffected. We discussed the results in relation to previous findings as well as the automaticity of anticipation

Self-rated health in middle-aged and elderly Chinese : distribution, determinants and associations with cardio-metabolic risk factors

Background: Self-rated health (SRH) has been demonstrated to be an accurate reflection of a person's health and a valid predictor of incident mortality and chronic morbidity. We aimed to evaluate the distribution and factors associated with SRH and its association with biomarkers of cardio-metabolic diseases among middle-aged and elderly Chinese. Methods: Survey of 1,458 men and 1,831 women aged 50 to 70 years, conducted in one urban and two rural areas of Beijing and Shanghai in 2005. SRH status was measured and categorized as good (very good and good) vs. not good (fair, poor and very poor). Determinants of SRH and associations with biomarkers of cardio-metabolic diseases were evaluated using logistic regression. Results: Thirty two percent of participants reported good SRH. Males and rural residents tended to report good SRH. After adjusting for potential confounders, residence, physical activity, employment status, sleep quality and presence of diabetes, cardiovascular disease, and depression were the main determinants of SRH. Those free from cardiovascular disease (OR 3.68; 95%CI 2.39; 5.66), rural residents (OR 1.89; 95% CI 1.47; 2.43), non-depressed participants (OR 2.50; 95% CI 1.67; 3.73) and those with good sleep quality (OR 2.95; 95% CI 2.22; 3.91) had almost twice or over the chance of reporting good SRH compared to their counterparts. There were significant associations -and trend- between SRH and levels of inflammatory markers, insulin levels and insulin resistance. Conclusion: Only one third of middle-aged and elderly Chinese assessed their health status as good or very good. Although further longitudinal studies are required to confirm our findings, interventions targeting social inequalities, lifestyle patterns might not only contribute to prevent chronic morbidity but as well to improve populations' perceived health
