MyJurnal

Objective: This study explored the stress and coping strategies among retired people in Malaysia. Methods: In-depth interviews were conducted with 36 elderly Malaysian subjects. This protocol was approved by the Ethics Committee of the Management and Science University. The data obtained were sorted into various categories. Results: A total number of 36 retired elderly people participated in this study. The majority of them were in the age group of 55-59 years old, females, Malay and married. The majority defined stress as pressure or tension. Financial difficulties, family and work problems were the main causes of stress in the majority. Also, the majority of respondents mentioned that they coped with stress by sharing problems with others, by resting and relaxing, and/or by doing housework during their free time. A few of them coped with stress by hanging out with friends, going shopping,
doing photography, travelling, going fishing, and doing sports. Conclusion: Financial difficulties, family and work problems were the main causes of stress among elderly people. They coped with stress by sharing problems with others, resting and relaxing, and/or doing housework during their free time.
Fulltext A patient who refused medical advice: the doctor and the patient should look for a common ground

Tong SF, Chen R

Malays Fam Physician, 2007;2(3):110-3.
PMID: 25606096 MyJurnal

Treatment refusal is a common encounter in clinical practice. The process of deciding to refuse treatment is often complex. It is our responsibility to try and understand this process of decision making and the underlying reasons for treatment refusal. Many of these reasons are often rational in the context where the decision is made. The patients could be making the best decision for themselves even if these decisions are not necessarily the best in our mind. We should at all times discuss our treatment options and assess their ability to make decisions in achieving common goals. These goals should balance our best treatment strategies and the patients' best interest. This article discusses the reasons underlying treatment refusal and how we can achieve a common goal with our patients.
Nutrition and cancer prevention: knowledge, attitudes and practices among young Malaysians

Al-Naggar RA, Chen R

Asian Pac J Cancer Prev, 2011;12(3):691-4.
PMID: 21627365

OBJECTIVE: The objective of this study was to determine the knowledge, attitudes and practices of university students toward nutrition related to cancer prevention.
METHODOLOGY: A total of 396 students from the Management and Science University (MSU) participated during the semester of March 2010. Stratified random sampling was used and consent was obtained before the questionnaire was distributed. ANOVA and the t-test were used for the univariate analysis and multiple linear regression was used for the multivariate analysis.
RESULTS: The participants ages ranged from 18 to 27 years (Mean ± SD = 23.3 ± 1.57), more than half being female (62.4%). The majority were 23 years old or younger, single, Malay and from non-Medical and Health Science faculties and with a family monthly income of less than 10,000 Ringgits Malaysia(79.5%; 99%, 65.9, 52.5%, 63.9%; respectively). Only 18.4% of participants reported a family history of cancer. About 32.1% had a medical check-up in the previous 12 months and 17.4% were smokers. Multivariate analysis showed the faculty type to be significantly associated with knowledge of cancer prevention (p = 0.04). Regular medical check-ups were associated with attitudes and practices of cancer prevention (p = 0.04, p=0.003 respectively), the latter being significantly influenced by sex, family history of cancer and smoking (p = 0.034, p=0.013, p=0.002; respectively).
CONCLUSION: The majority of participants had poor knowledge of nutrition as related to cancer prevention. Attention should be given to regular medical check-ups, awareness of family history and smoking influence.

Al-Naggar RA, Chen R

Asian Pac J Cancer Prev, 2011;12(4):1023-9.
PMID: 21790245

The objective of this study is to determine the prevalence and associated factors of vitamin-mineral supplements use among Management and Science University students. The cross-sectional study protocol was approved by the Ethics and Research Committee and questionnaires were distributed randomly using simple random sampling to students from all faculties and consent was obtained. The data were analyzed using the SPSS version 13. Total number of the participants in this study is 105. More than half of them were female, older than 20 years of age and Malay (58.1%, 61.9 and 61.9% respectively). The prevalence of vitamin-mineral supplement use was 43%, the main reasons being 'to maintain good health' 80%, followed by 'to ensure adequate nutrition' (10.5%). There was a significant positive association with monthly household income and BMI (P=0.039; P=0.048), with significant dependence on race and knowledge about vitamin-mineral supplements (P=0.002). There was a significant difference between medical and health sciences as compared to non-medical and health science faculties (p =0.05). The conclusion is that although the prevalence of vitamin-mineral supplement use among university students is relatively high, many of them do not have accurate information about supplements. Therefore, there is a need to provide them with education and access to scientific and unbiased information.

Asian Pac J Cancer Prev, 2010;11(6):1515-21.
PMID: 21338190

OBJECTIVE: The objective of this study is to explore the perceptions and opinions of young women about human papilloma virus (HPV) vaccination and associated barriers.
METHODOLOGY: This qualitative in-depth interview study was conducted in January 2010 with 30 university students from different faculties, i.e.:International Medical School (IMS), Faculty of Health and Life Sciences (FHLS), Faculty of Business Management and Professional Studies (FBMP) and Faculty of Information Sciences and Engineering (FISE) of the Management and Science University (MSU), Shah Alam, Malaysia. After consent was obtained from all participants, the interviewer wrote down the conversations during the interview sessions. The data obtained were classified into various categories and analyzed manually.
RESULTS: The majority of participants 25 (83%) had heard about cervical cancer, while 16 (53.3%) have never heard of HPV. Only five participants (17%) mentioned that HPV is the cause of cervical cancer. Ten participants (33.3%) did not know any causes. The majority 16 (53.3%) did not know the mode of HPV transmission. The majority of participants 22 (73.3%) mentioned that they had not been vaccinated against HPV. Out of 22, 16 (53.3%) agreed to be vaccinated in the future to protect themselves from cervical cancer and five (17%) participants mentioned they are not willing because of the uncertain safety of the available vaccines and their side effects.
CONCLUSION: This study showed relatively poor knowledge about HPV and its vaccines, pointing to urgency of educational campaigns aimed at students in the public and government universities to promote HPV vaccination among this highly eligible population.

PMID: 21875261

INTRODUCTION: The etiology of breast cancer is still unknown and adequate primary prevention strategies or interventions are still not possible. Therefore, early detection remains the first priority and regular practice of breast self-examination (BSE) influences treatment, quality of life, survival, and prognosis of breast cancer patients.
OBJECTIVES: The objective of this study was to determine the practices and barriers towards breast self-examination among young Malaysian women.
METHODOLOGY: Cross-sectional study was conducted among 251 female students at the Management and Science University, Shah Alam, Selangor, Malaysia. Questionnaires were distributed at gathering places such as the university cafeteria, the university plaza, the Islamic center, and at the library. In addition, questionnaires were distributed in the lecture halls. The proposal of this study was approved by the Ethics and Research Committee of Management and Science University. Data was analysis using SPSS version 13, t-test was used to analyze the associated factors toward the practice of BSE.
RESULTS: A total number of 251 students participated in this study. The majority of them were older than 20 years old,of Malay racial origin, single and from urban areas (66.5%; 63.7%; 96%; 70.9% respectively). Regarding their lifestyle practices, the majority of participants do exercise, are non-smokers and do not drink alcohol (71.3%; 98.4%; 94.4% respectively). More than half of the study participants mentioned that they have practiced BSE (55.4%). Regarding the sources of information about BSE, the majority mentioned that radio and TV were their main sources of information (38.2%). Age, exercise and family history of cancer significantly influenced the practice of BSE (p = 0.045; p=0.002; p=0.017 respectively). Regarding the barriers to BSE, the majority who never practiced BSE mentioned that lack of knowledge, not having any symptoms, and being afraid of being diagnosed with breast cancer were the main barriers to practicing BSE (20.3%; 14.3%; 4.4% respectively).
CONCLUSION: More than half of the participants practiced BSE. Age, exercise and family history of cancer significantly influenced the practice of the BSE. Lack of knowledge, not having any symptoms and being afraid of being diagnosed with breast cancer were the main barriers to practicing BSE. There is an urgent need to develop a continuous awareness campaign among university students on the importance of performing BSE.

PMID: 21627354

OBJECTIVE: The objectives were to determine the prevalence and associated factors for smoking among university students in Malaysia.
METHODOLOGY: A cross-sectional study was conducted among 199 students in the period from December of academic year 2009 until April of academic year 2010 in Management and Science University (MSU), Shah Alam, Selangor, Malaysia. The questionnaire was distributed randomly to all faculties of MSU by choosing one of every 3 lecture rooms, as well as the library and cafeterias of the campus randomly by choosing one from every 3 tables. Questions concerned socio-demographic variables, knowledge, attitudes and practice toward smoking. Participant's consent was obtained and ethical approval was provided by the ethics committee of the University. Data entry and analysis were performed using descriptive statistics, chi square test, Student t- test and logistic multiple regression with the SPSS version 13.0, statistical significance being concluded at p < 0.05.
RESULTS: About one third of students were smokers (29%). The most important reason of smoking was stress (20%) followed by 'influenced by friends' (16 %). Prevalence of smoking was significantly higher among male and those in advanced semesters (p = >0.001, p = 0.047). Smokers had low level of knowledge (p < 0.05), had wrong beliefs on smoking (p < 0.05), and negative attitude toward tobacco control policies compared to non smokers (p < 0.05). On multiple logistic regression, significant predictors of smoking in the model were gender (p = 0.025), age (p = 0.037), semester of study (p = 0.025) and attitude toward smoking (p < 0.001).
CONCLUSION: This study found that 29% of university students were smokers. Males and students in advanced semesters were more likely to smoke. The results provide baseline data to develop an anti-smoking program to limit smoking in the university by implementing policies against smoking.

PMID: 20104962

A cross-sectional study was conducted at the main hospitals in Sana'a, Yemen to determine the attitude and practice of Yemen female doctors on mammography screening. Study subjects were all female doctors who were on duty during the questionnaire distribution. Those who agreed to participate were given the questionnaire to complete. Descriptive statistics were used to analyse socio-demographic variables and variables related to general health. Participants in this study were 105 female doctors with mean age of 32.1 years (SD = 7.17). Thirty-four respondents (36.6%) did not send asymptomatic women for mammography screening. The reasons were because of high cost (58.0%, n= 25), availability of other methods (23.3%, n= 10), instrument not available (11.6%, n= 5) and high risk of radiation (7.0%, n= 3). Twenty-five participants (26.9%) sent patients on regular basis if there was a family or personal history of breast cancer. Twenty-three participants (24.7%) sent the patients for mammogram screening every year regardless of the patients'history or symptoms. Although most doctors (36.5%) do not refer patients for mammography screening, seventy-seven (74.0%) indicated that they would refer patients for mammography screening on personal request by the patients. This study showed a low percentage of doctors who referred patients for routine mammography. The major reason given was the high cost of the procedure.

Lim SY, Mason WP, Young NP, Chen R, Bower JH, McKeon A, et al.

Arch. Neurol., 2009 Oct;66(10):1285-7.
PMID: 19822786 DOI: 10.1001/archneurol.2009.203

OBJECTIVE:
To describe and provide audiovisual documentation of a syndrome of polymyoclonus, laryngospasm, and cerebellar ataxia associated with adenocarcinoma and multiple neural cation channel autoantibodies.

DESIGN:
Case report with video.

SETTING:
University hospitals. Patient A 69-year-old woman presented with subacute onset of whole-body tremulousness and laryngospasm attributed to gastroesophageal reflux.

RESULTS:
Further evaluation revealed polymyoclonus, cerebellar ataxia, and laryngospasm suspicious of an underlying malignant neoplasm. Surface electromyography of multiple limb muscles confirmed the presence of polymyoclonus. The patient was seropositive for P/Q-type voltage-gated calcium channel antibody; subsequently, whole-body fluorine 18 fluorodeoxyglucose positron emission tomography and cervical lymph node biopsy revealed widespread metastatic adenocarcinoma. Follow-up serologic evaluation revealed calcium channel antibodies (P/Q type and N type) and potassium channel antibody.

CONCLUSIONS:
We highlight the importance of recognizing polymyoclonus. To our knowledge, this is also the first description of a syndrome of polymyoclonus, laryngospasm, and ataxia associated with adenocarcinoma and these cation channel antibodies.

Survival after diagnosis of cancer is one of the major outcome measurements and a key criterion for assessing quality of cancer control related to both the preventive and the therapeutic level. The purpose of this study was to determine the 8-year survival time in Malaysia based on socio-demographic and clinical characteristics. A retrospective study of 472 Malaysian women with breast cancer from the Medical Record Department at University Kebangsaan Malaysia Medical Centre (UKMMC) was therefore performed with survival analysis carried out using the Kaplan-Meier with log-rank test for univariate analysis and Cox-regression for multivariate analysis. Women who had cancer or family history of cancer had a longer 8-year survival time (p = 0.008) compared with others who did not have such a history. Tamoxifen use, positive oestrogen receptor status, and race were prognostic indicators for 8-year survival time (p = 0.036, p = 0.018, p = 0.053, respectively) in univariate analysis. Multivariate analysis showed that being Malays and having no family history of cancer were independent prognostic factors for shorter survival time (p = 0.008, p = 0.012, respectively). In conclusion, being Chinese and having a family history of cancer are predictors of longer survival among the Malaysian breast cancer women.
Fulltext Live virus vaccines based on a yellow fever vaccine backbone: standardized template with key considerations for a risk/benefit assessment

Monath TP, Seligman SJ, Robertson JS, Guy B, Hayes EB, Condit RC, et al.

Vaccine, 2015 Jan 01;33(1):62-72.
PMID: 25446819 DOI: 10.1016/j.vaccine.2014.10.004

The Brighton Collaboration Viral Vector Vaccines Safety Working Group (V3SWG) was formed to evaluate the safety of live, recombinant viral vaccines incorporating genes from heterologous viruses inserted into the backbone of another virus (so-called "chimeric virus vaccines"). Many viral vector vaccines are in advanced clinical trials. The first such vaccine to be approved for marketing (to date in Australia, Thailand, Malaysia, and the Philippines) is a vaccine against the flavivirus, Japanese encephalitis (JE), which employs a licensed vaccine (yellow fever 17D) as a vector. In this vaccine, two envelope proteins (prM-E) of YF 17D virus were exchanged for the corresponding genes of JE virus, with additional attenuating mutations incorporated into the JE gene inserts. Similar vaccines have been constructed by inserting prM-E genes of dengue and West Nile into YF 17D virus and are in late stage clinical studies. The dengue vaccine is, however, more complex in that it requires a mixture of four live vectors each expressing one of the four dengue serotypes. This vaccine has been evaluated in multiple clinical trials. No significant safety concerns have been found. The Phase 3 trials met their endpoints in terms of overall reduction of confirmed dengue fever, and, most importantly a significant reduction in severe dengue and hospitalization due to dengue. However, based on results that have been published so far, efficacy in preventing serotype 2 infection is less than that for the other three serotypes. In the development of these chimeric vaccines, an important series of comparative studies of safety and efficacy were made using the parental YF 17D vaccine virus as a benchmark. In this paper, we use a standardized template describing the key characteristics of the novel flavivirus vaccine vectors, in comparison to the parental YF 17D vaccine. The template facilitates scientific discourse among key stakeholders by increasing the transparency and comparability of information. The Brighton Collaboration V3SWG template may also be useful as a guide to the evaluation of other recombinant viral vector vaccines.
