Abstract
BACKGROUND This study aimed to evaluate parental perception of neighbourhood environments and safety in association with children's physical activity among primary school children in Klang, Selangor, Malaysia. METHODS A total of 250 children (9-12 years of age) and their parents participated in this cross-sectional study. Physical Activity Questionnaire for Older Children and Neighbourhood Environmental Walkability Scale as well as questions on constrained behaviours (avoidance and defensive behaviours) were used to assess the children's physical activity and parental perception of neighbourhood environment and safety, respectively. RESULTS More than one-third (36.0%) of the children were physically inactive compared with only a small percentage (4.8%) who were physically active, with boys achieving higher physical activity levels than girls (t = 2.564, P = 0.011). For the environmental scale, parents' perception of land-use mix (access) (r = 0.173, P = 0.006), traffic hazards (r = -0.152, P = 0.016) and defensive behaviour (r = -0.024, P = 0.143) correlated significantly with children's physical activity. In multiple linear regression analysis, child's gender (β = -0.226; P = 0.003), parent's education (β = 0.140; P = 0.001), household income (β = 0.151; P = 0.024), land-use mix (access) (β = 0.134; P = 0.011) and defensive behaviour (β = -0.017; P = 0.038) were significantly associated with physical activity in children (R = 0.349, F = 6.760; P < 0.001), contributing 12.2% of the variances in physical activity of the children. CONCLUSION Results highlight the links between parental perception of neighbourhood environments, safety and constrained behaviours with their children's participation in active play. Interventions aimed to increase actual and perceived safety and reduce perceptions of risk by parents in safe neighbourhoods can be targeted to increase children's physical activity in their local neighbourhoods.

Abstract
PURPOSE To compare the effects of a high-calcium vitamin D-fortified milk with added FOS-inulin versus regular milk on serum parathyroid hormone, and bone turnover markers in premenopausal (Pre-M) and postmenopausal (PM) women over 12 weeks. METHODS Premenopausal women (n = 136, mean age 41 (±5) years) and postmenopausal women [n = 121, mean age 59 (±4) years] were recruited, and each age group randomised into two groups to take two glasses per day of control = regular milk (500 mg calcium per day) or intervention (Int) = fortified milk (1000 mg calcium for pre-M women and 1200 mg calcium for PM women, 96 mg magnesium, 2.4 mg zinc, 15 µg vitamin D, 4 g FOS-inulin per day). At baseline, week 4 and week 12 serum minerals and bone biochemical markers were measured and bone density was measured at baseline. RESULTS Mean 25-hydroxyvitamin D [25(OH) vitamin D3] levels among groups were between 49 and 65 nmol/L at baseline, and over the 12 weeks of supplementation, the fortified milk improved vitamin D status in both Int groups. CTx-1 and PINP reduced significantly in both Pre-M and PM groups over the 12 weeks, with the changes in CTx-1 being significantly different (P < 0.035) between PM control and PM Int groups at week 12. Parathyroid hormone levels were significantly reduced in all groups over time, except for control PM group where levels increased at 12 weeks. CONCLUSION The overall pattern of responses indicates that while both regular milk and fortified milk reduce bone resorption in young and older women, fortified milk is measurably more effective.

Abstract
BACKGROUND Double-burden of malnutrition (DBM) is an emerging public health concern among the Orang Asli (indigenous peoples) of Peninsular Malaysia. This study aimed to identify the presence of DBM at the community and household levels in Orang Asli population and its associated demographic and socio-economic factors. METHODS This cross-sectional study was conducted in 11 Orang Asli villages surrounding the Krau Wildlife Reserve, Peninsular of Malaysia from October 2011 to January 2012. Of 438 households, a total of 981 adults and 304 children who met the study criteria agreed to participate. About 160 households were further selected with pairs of children aged 3-59 months and non-pregnant mothers aged 15-55 years. Demographic and socio-economic data were obtained using interviewer-administered questionnaire while weight and height were measured using standard procedures. Double-burden of malnutrition was defined as overweight/obese mother-underweight child (OWOBM/UWC), overweight/obese mother-stunted child (OWOBM/STC) or overweight/obese mother-underweight or/and stunted child (OWOBM/UWSTC). Binary logistic regression identified the demographic and socio-economic factors associated with double-burden households. RESULTS About 26 % of overweight and obese adults coexisting with high proportions of underweight (49%) and stunted (64%) children in these Orang Asli villages. There was a higher prevalence of households with OWOBM/UWSTC (20%) and OWOBM/STC (19.4%) than households with OWOBM/UWC (12.5%). Boys (P < 0.05), older age mothers (P < 0.05), mothers with higher education (P < 0.05) and households with income per capita less than USD 29.01 (RM 97.00) (P < 0.01) were associated with higher odds of OWOBM/STC. Jah Hut (P < 0.05) and higher number of children (P < 0.05) were significantly associated with lower odds of OWOBM/UWC. CONCLUSIONS The occurrence of double-burden of malnutrition in Orang Asli population deserves attention. Poverty reduction, access to quality diet and improved health and nutrition literacy are among strategies that could address the coexistence of DBM in this population.

Abstract
BACKGROUND The study aimed to determine the association between body mass index (BMI)-for-age and health-related quality of life (HRQOL) among high school students in Tehran. METHODS A total of 465 high school students (227 girls and 238 boys) and their parents were participated in this cross-sectional study. Body weight and height of the students were measured. For assessing HRQOL, both adolescent self-report and parent proxy-report of the Persian version of Pediatric Quality of Life Inventory (PedsQL™4.0) questionnaire were completed by adolescents and their parents respectively. RESULTS The prevalence of overweight and obesity (38.5%) was higher than severe thinness and thinness (2.8%). Mean of adolescent self-reported and parent proxy-reported HRQOL total score were 80.26 ± 12.07 and 81.30 ± 14.08 respectively. In terms of HRQOL subscale scores, the highest subscale score of HRQOL was reported in social functioning (87.27 ± 14.40) and the lowest score was reported in emotional functioning (69.83 ± 18.69). Based on adolescent self-report, adolescent boys had significantly higher mean score for total and all subscale scores of HRQOL compared with girls (P < 0.05). BMI-for-age was inversely correlated to adolescent self-reported HRQOL total score (r = -0.25, P < 0.05). Based on adolescents self-report, HRQOL total score was significantly different by body weight status (F = 16.16, P < 0.05). Normal weight adolescents had significantly higher HRQOL total score compared with overweight (mean difference: 7.32; P < 0.05) and obese adolescents (mean difference: 9.10, P < 0.05). The HRQOL total score was not significantly different between normal weight and underweight adolescents (mean difference: 1.65, P = 0.96). However, based on parent proxy-reports, HRQOL total score was not significantly different by body weight status (F = 2.64, P = 0.059). CONCLUSION More than one-third of adolescents were overweight and obese. BMI-for-age was inversely correlated to adolescent self-reported HRQOL. Based on adolescents' perspective, overweight and obese adolescents had poorer HRQOL compared with normal weight adolescents. Intervention studies are needed to improve the HRQOL of overweight and obese adolescents in Tehran.

Abstract
A quantum interface between a propagating photon used to transmit quantum information and a long-lived qubit used for storage is of central interest in quantum information science. A method for implementing such an interface between dissimilar qubits is quantum teleportation. Here we experimentally demonstrate transfer of quantum information carried by a photon to a semiconductor spin using quantum teleportation. In our experiment, a single photon in a superposition state is generated using resonant excitation of a neutral dot. To teleport this photonic qubit, we generate an entangled spin-photon state in a second dot located 5 m away and interfere the photons from the two dots in a Hong-Ou-Mandel set-up. Thanks to an unprecedented degree of photon-indistinguishability, a coincidence detection at the output of the interferometer heralds successful teleportation, which we verify by measuring the resulting spin state after prolonging its coherence time by optical spin-echo.

Abstract
A retrospective analysis was performed on 31 consecutive locally advanced or metastatic breast cancer patients who commenced exemestane 25mg/d orally following previous treatment with Tamoxifen and a non-steroidal third-generation aromatase inhibitor (AI). Patients were seen 3 monthly until clinical or radiological disease progression. Median age was 64 years (range 34-90 yrs). The average number of recurrences before starting exemestane was three (range 1-6). There were two complete responses (CR), four partial responses (PR), 12 with stable disease (SD) and 12 with progressive disease (PD). Objective response rate (CR+PR) was 19.4% and overall clinical benefit (CR+PR+SD >or= 24 weeks) was 54.8%. The median durations of objective response and overall clinical benefit were 18 and 14 months, respectively. This data support the anti-tumour activity of exemestane 25mg daily in patients with locally advanced and/or metastatic breast cancer who have been previously exposed to non-steroidal AIs and Tamoxifen.

Abstract
AIMS To assess the treatment outcomes and toxicity of conformal high dose rate (HDR) brachytherapy boost as a means of radiation dose escalation in patients with localised prostate cancer. MATERIALS AND METHODS Between December 1998 and July 2004, 65 consecutive patients with localised prostate cancer (magnetic resonance imaging-staged T1-3 N0 M0) were treated with external beam radiation therapy (EBRT) followed by two fractions of HDR iridium-192 brachytherapy. The patients selected this treatment modality in preference to entering an ongoing randomised phase 3 trial. Any pre-treatment serum prostate-specific antigen (PSA) and Gleason score were included. The primary end point was biochemical disease-free progression. Late treatment-related morbidity was graded according to the Radiation Therapy Oncology Group and the European Organization for Research and Treatment of Cancer criteria. RESULTS The median patient age was 67.3 years (range 47.9-80). Sixty patients (92.3%) had intermediate- to high-risk disease defined by clinical stage, presenting PSA and Gleason score/World Health Organisation (WHO) grade. With a median follow-up of 3.5 years (range 0.6-5.8), two patients had died of metastatic disease and another four patients had PSA relapse, giving a 3-year actuarial biochemical disease-free progression of 90.8%. Three patients (4.6%) had acute grade 3 genitourinary toxicity, in the form of urinary retention. Late grade 3 and 4 genitourinary toxicities occurred in four patients (6.2%) and one patient (1.5%), respectively. No late gastrointestinal toxicities were observed. CONCLUSIONS These results suggest that the combined modality of conformal HDR brachytherapy and EBRT is a feasible treatment modality with acceptable acute and late toxicities, comparable with those of EBRT alone. It offers an attractive conformal treatment modality with the potential of further dose escalation in the treatment of localised prostate cancer.

Abstract
This study was aimed at evaluating the consistency of driving advice given by treating clinicians to patients diagnosed with brain tumours. Secondary aims include assessing the awareness of current driving guidelines and whether or not there was a need for more specific guidelines in this group of patients. This was undertaken utilizing a scenario-based postal survey. The results show an overall poor consistency in the answers provided for each case scenario. 73.1% respondents were not aware of any current driving guidelines. Of those who were aware of driving guidelines, 67.7% wanted more specific guidelines to be developed. Possible explanations for this are a lack of awareness of the existence of any driving guidelines and a lack of objective criteria in the current driving guidelines. The authors recommend that the current driving guidelines be comprehensively distributed to clinicians who treat patients with brain tumours, as well as forming a multi-disciplinary working party to develop more specific and objective driving guidelines.
