Integrating real-world data in cost-effectiveness analysis of universal HLA-B*15:02 screening in Malaysia.

AIMS: Despite the availability of newer antiseizure medications, carbamazepine (CBZ) remains the gold standard. However, patients of Asian ancestry are susceptible to CBZ-related severe cutaneous adverse reactions. Universal HLA-B*15:02 screening is a promising intervention to address this. With the increasing recognition of integrating real-world evidence in economic evaluations, the cost-effectiveness of universal HLA-B*15:02 screening was assessed using available real-world data in Malaysia. METHODS: A hybrid model of a decision tree and Markov model was developed to evaluate 3 strategies for treating newly diagnosed epilepsy among adults: (i) CBZ initiation without HLA-B*15:02 screening (current practice); (ii) universal HLA-B*15:02 screening prior to CBZ initiation; and (iii) alternative prescribing without HLA-B*15:02 screening. The model was populated with real-world inputs derived from the Malaysian population. From a societal perspective, base-case analysis and sensitivity analyses estimated the costs and outcomes over a lifetime. Incremental cost-effectiveness ratios were calculated. RESULTS: In the base-cases analysis, universal HLA-B*15:02 screening yielded the lowest total costs and the highest total quality-adjusted life years (QALYs) gained. Compared with current practice, universal screening was less costly by USD100 and more effective by QALYs increase of 0.1306, while alternative prescribing resulted in 0.1383 QALYs loss at additional costs of USD332. The highest seizure remission rate (56%) was estimated for universal HLA-B*15:02 screening vs. current practice (54%) and alternative prescribing (48%). CONCLUSION: Our study suggests that universal HLA-B*15:02 screening is a cost-effective intervention in Malaysia. With the demonstrated value of real-world evidence in economic evaluations, more relevant standardization efforts should be emphasized to better inform decision-making.

Breast conserving surgery versus mastectomy: the effect of surgery on quality of life in breast cancer survivors in Malaysia.

BACKGROUND: In the competitive health care environment, patient satisfaction and quality of life (QoL) have become the subject of interest to evaluate the efficacy of therapeutic interventions as we experience improved breast cancer survival in modern times. The knowledge of the long-term effects of surgery on the QoL in breast cancer patients is currently limited in the Asian setting. The purpose of this longitudinal study is to evaluate the QoL of early-stage breast cancer patients undergoing mastectomy and breast-conserving surgery (BCS). METHODS: In this prospective cohort study, the QoL of 208 patients who underwent mastectomy and the BCS treatment were assessed, using the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire. The questionnaire was administered at the baseline, 6 and 12 months following diagnosis. One-way ANCOVA was used for statistical analysis. RESULTS: A total of 208 female survivors of Stage 0-II breast cancer were included, among them 47.1% underwent BCS and 52.9% underwent mastectomy. Older (63.3%), Chinese women (63.6%), and patients with primary education (71.7%) were more likely to undergo mastectomy. At baseline, no significant differences were observed for QoL in both treatment groups. At 6 months, patients who underwent BCS had better social functioning scales( P = 0.006) and worse symptom scales for dyspnoea (P = 0.031), compared to mastectomy patients. One year after diagnosis, the role functioning score of the mastectomy group was significantly higher than the BCS group, specifically among patients who had undergone chemotherapy (P = 0.034). CONCLUSION: Patients who underwent BCS had better social functioning and worse dyspnoea symptoms compared to patients undergoing mastectomy at six months. During one year, there were only significant improvements in the role functioning among the mastectomy groups compared to the BCS groups. After further stratification, only mastectomy patients who received chemotherapy exhibited improved role functioning compared to patients those who did not undergo chemotherapy. Providing social and physical support postoperatively and monitoring patients for cancer worry, or other symptoms in the long-term survivorship period would be important to ensure optimal QoL.

Women's health beliefs and uptake of breast cancer screening in Malaysia.

OBJECTIVES: This study investigated women's health beliefs, the use of breast cancer (BC) screening services, and the factors that potentially influence uptake of screening. METHODS: Face-to-face interviews were conducted with a randomly selected community sample of 992 women (>40 years old) in Selangor State, Malaysia. RESULTS: Approximately 35% of women received a clinical breast examination (CBE) and 27% had a mammogram within the last 1 to 2 years. The regression analyses indicated that Chinese ethnicity has higher perceived susceptibility to BC compared to Malay ethnicity (mean 7.74, SD: 2.75; 95% CI 0.09, 1.03) whilst a lower perceived susceptibility was observed in women aged ≥70 years (mean 6.67, SD: 3.01; 95% CI -1.66, -0.24) compared to women aged 40-49 years. Indian Malaysian women (mean 16.87, SD: 2.59; 95% CI 0.12, 1.01) and women who had received a CBE (mean 16.10, SD:2.35; 95% CI 0.18, 0.89) were more likely to have higher perceived benefits scoring. Indian ethnicity, secondary education and tertiary education, top 20% income group, past history of CBE and mammogram uptake were significantly associated with lower barriers scoring. CONCLUSIONS: There is a need to target BC screening uptake improvement programmes towards communities in which women experience disadvantages related to income, education, employment, and, in particular, to tailor programmes to take into consideration differences between ethnic groups regarding their beliefs about cancer screening.

Perceptions of eating practices and physical activity among Malaysian adolescents in secondary schools: a qualitative study with multi-stakeholders.

OBJECTIVE: To conduct formative research using qualitative methods among stakeholders of secondary schools to explore their perceptions, barriers and facilitators related to healthy eating and physical activity (PA) among Malaysian adolescents. DESIGN: A qualitative study involving eight focus groups and twelve in-depth interviews. Focus groups and interviews were recorded and transcribed verbatim. An inductive thematic analysis approach was used to analyse the data. SETTING: Four secondary schools in Perak and Selangor states (two urban and two rural schools) in Malaysia. PARTICIPANTS: Focus groups were conducted with seventy-six adolescents aged 13-14 years, and in-depth interviews were conducted with four headmasters, four PA education teachers and four food canteen operators. RESULTS: Stakeholders thought that adolescents' misperceptions, limited availability of healthy options, unhealthy food preferences and affordability were important challenges preventing healthy eating at school. Low-quality physical education (PE) classes, limited adolescent participation and teachers' commitment during lessons were perceived as barriers to adolescents being active at school. Affordability was the main challenge for adolescents from rural schools. Stakeholders perceived that a future school-based intervention should improve the availability and subsidies for healthy foods, provide health education/training for both adolescents and PE teachers, enhance active adolescent participation in PE and develop social support mechanisms to facilitate engagement with PA. CONCLUSIONS: These findings provide important insights into developing school-based lifestyle interventions to improve healthy eating and strengthening PA of Malaysian adolescents.

Change in public awareness of colorectal cancer symptoms following the Be Cancer Alert Campaign in the multi-ethnic population of Malaysia.

BACKGROUND: Colorectal cancer (CRC) cases are detected late in Malaysia similar to most Asian countries. The Be Cancer Alert Campaign (BCAC) was a culturally adapted mass media campaign designed to improve CRC awareness and reduce late detection in Malaysia. The evaluation of the BCAC-CRC aimed to assess campaign reach, campaign impact and health service use. METHODS: Participants aged ≥40 years (n = 730) from randomly selected households in Selangor State Malaysia, completed interview-based assessments. Campaign reach was assessed in terms of responses to an adapted questionnaire that was used in evaluations in other countries. The impact of the campaign was assessed in terms of awareness, confidence to detect symptoms and self-efficacy to discuss symptoms with a doctor as captured by the Cancer Awareness Measure (CAM). CAM was administered before-and-after campaign implementation and responses by BCAC recognisers (i.e. participants who recognised one or more of the BCAC television, radio or print advertisements when prompted) and non-recognisers (i.e. participants who did not recognise any of the BCAC advertisements) were compared analytically. Logistic regression analysed comparative differences in cancer awareness by socio-demographic characteristics and recognition of the BCAC materials. RESULTS: Over 65% of participants (n = 484) recognised the BCAC-CRC. Campaign-recognisers were significantly more likely to be aware of each CRC symptom at follow-up and were more confident about noticing symptoms (46.9% vs 34.9%, p = 0.018) compared to non-recognisers. There was no difference between groups in terms of self-efficacy to see a doctor about symptoms. Improved symptoms awareness at follow-up was lower for Indians compared to Malays (adjusted odds ratio (OR) 0.53, 95% Confidence Interval (CI): 0.34, 0.83, p = 0.005). Health service use data did not indicate an increase in screening activity during or immediately after the campaign months. CONCLUSION: Overall, the findings of the evaluation indicated that the culturally adapted, evidence-based mass media intervention improved CRC symptom awareness among the Malaysian population; and that impact is more likely when a campaign operates a differentiated approach that matches modes of communication to the ethnic and social diversity in a population.

The longitudinal relationship between dietary intake, physical activity and muscle strength among adolescents.

The longitudinal relationship between muscle strength, dietary intake and physical activity among adolescents is not well understood. We investigated the trend and longitudinal effects of dietary intakes and physical activity scores on muscle strength in adolescents. This prospective cohort study consisted of 436 adolescents (134 males; 302 females) aged 13 years at baseline (2012) who were followed up at the ages of 15 (2014) and 17 (2016) years, respectively. We measured muscle strength using a calibrated hand dynamometer, estimated dietary intake with a 7-d dietary history and physical activity scores with a validated physical activity questionnaire for older children. A generalised estimating equation was used to examine the effect of dietary intakes and physical activity on muscle strength changes. The analysis was performed separately by sex. The muscle strength for males and females had increased within the 5-year period. The dietary intakes (energy and macronutrients) also increased initially but plateaued after the age of 15 years for both sexes. Females recorded a significant declining trend in physical activity scores compared with males as they grew older. A significant positive longitudinal relationship was found between protein (ß = 0·035; P = 0·016), carbohydrate intake (ß = 0·002; P = 0·013) and muscle strength among males. However, no longitudinal relationship was found between dietary intake, physical activity and muscle strength among females. Higher protein and carbohydrate intake among males was associated with higher muscle strength but was not observed in females. Nutrition and physical activity focusing on strength building are required in early adolescence and need to be tailored to males and females accordingly.

Why girls get married early in Sarawak, Malaysia - an exploratory qualitative study.

BACKGROUND: Child marriage, a marriage that involves someone under the age of 18 years, is a long-standing social issue in Sarawak state, Malaysia. The state has taken several measures to improve situations of inequity for women who get married early; however, the practice is still a common part of the tradition and culture. The aim of this study was to explore the factors leading to child marriage in Sarawak state, Malaysia. METHODS: This was an exploratory qualitative study conducted via semi-structured interviews with twenty-two women who were married when they were younger than 18 years old in Kuching, Sarawak, Malaysia. Participants were recruited through purposive and convenient sampling with the use of data from a reproductive health clinic and recruitment in villages. Thematic analysis was used for data analysis. RESULTS: Four overarching themes were identified: health risk behaviour, family poverty, early marriage as fate, and family disharmony. CONCLUSIONS: In-depth understanding of the unique factors leading to child marriage locally will facilitate the introduction of new approaches to interventions to eradicate child marriage in Sarawak state, Malaysia.

Estimating the Population Size of People Who Inject Drugs in Malaysia for 2014 and 2017 Using the Benchmark-Multiplier Method.

Background: As hepatitis C elimination efforts are launched, national strategies for screening and treatment scale-up in countries, such as Malaysia, must be designed and implemented. Strategic information, including estimates of the total number of patients chronically-infected with hepatitis C virus (HCV) and the size of key populations, such as people who inject drugs (PWID), is critical to informing these efforts. For Malaysia, the estimate of the PWID population size most frequently reported in global systematic reviews is for the year 2009. Objectives: To support ongoing national HCV planning efforts, we aimed to estimate the national population size of active PWID in Malaysia, for the years 2014 and 2017. Methods: To estimate the PWID population size, we applied standard benchmark-multiplier methodology, frequently used for PWID population size estimation, and extended it by adjusting for cessation of injecting drug use within the benchmark and calculating statistical uncertainty intervals. Results: The estimated active PWID population size was 153,000 (95% uncertainty interval (UI): 136,000-172,000) for 2014 and 156,000 (95% UI: 137,000-188,000) for 2017. Conclusions/importance: This updated estimate of the active PWID population size in Malaysia will help inform effective planning for the scale-up of HCV screening and treatment services. The proposed methodology is applicable to other countries that maintain national HIV registries and have conducted Integrated Biological and Behavioral Surveys among active PWID.

Assessing the willingness to pay for HIV counselling and testing service: a contingent valuation study in Lagos State, Nigeria.

HIV/AIDS is a major health issue faced by the world, generally, but particularly sub-Saharan Africa. Nigeria ranked third in the world by number of people living with HIV/AIDS in 2019. Despite prominent HIV counselling and testing (HCT) intervention programmes, Nigeria faces serious challenges, such as inadequate funding and low utilisation rates. Paucity of research into such a critical topic has restricted the capacity of policy makers to address the problem adequately. Consequently, a cross-sectional study was carried out using the contingent valuation method to assess the economic quantum of payment and determining factors associated with people's willingness to pay for HCT services. Data were collected from 768 people selected by convenience sampling of three local government areas - Alimosho, Ikorodu and Surulere in Lagos State, Nigeria. Data were analysed using descriptive statistics, chi-square, Mann-Whitney, and general linear regression model analysis. Findings show that 75% of respondents were willing to pay an average fee of N1 291 ($4.22) for HCT services. Significant determinants of willingness to pay were: income; knowledge of someone living with HIV or died of AIDS; worry about HIV infection; and fear of HIV-related stigma. The findings offer vital information germane to co-payment schemes aimed at financial sustainability of HCT and HIV/AIDS programmes in Nigeria.

Dietary and physical activity patterns related to cardio-metabolic health among Malaysian adolescents: a systematic review.

BACKGROUND: A sedentary lifestyle and an unhealthy diet are major factors in the increasing prevalence of obesity among Malaysian adolescents. The purpose of this systematic review is to compile the evidence from observational and intervention studies among Malaysian adolescents to evaluate the associations between diet and physical activity (PA) as determinants of cardio-metabolic risk factors. METHODS: A systematic search of Medline via the PubMed, Science Direct, Cochrane Review and Web of Science databases was conducted for studies on the associations between diet and PA factors and cardio-metabolic risk factors among Malaysian adolescents aged 13-18 years that were published until 31 August 2017. The search results were independently screened and extracted by two reviewers. RESULTS: From over 2,410 references retrieved, 20 full texts articles were screened as potentially relevant. Seventeen (16 cross-sectional and one intervention) met the inclusion criteria for data extraction and analysis. All 17 studies were rated as poor quality and the majority had made insufficient adjustment for confounders. As regards the effect of diet and PA on cardio-metabolic health, the intakes of energy (n = 4) and macronutrients (n = 3) and meal frequency (n = 5) were the most commonly studied dietary factors, while the PA score and level were the most commonly studied PA factors. In addition, BMI and body weight were the most common cardio-metabolic health outcomes. The studies showed that obese and overweight adolescents consume significantly more energy and macronutrients. They are also more likely to skip their daily meals compared to their normal weight peers. In most studies, the direction of the PA effect on body weight was unclear. Some studies found that higher PA is associated with a lower risk of overweight and obesity. However, the associations are often small or inconsistent, with few studies controlling for confounding factors. CONCLUSIONS: This review identified a lack of evidence and well-conducted prospective studies on the effect of diet and PA on cardio-metabolic health of Malaysian adolescents.

Provider Costs of Treating Colorectal Cancer in Government Hospital of Malaysia.

BACKGROUND: The incidence of colorectal cancer (CRC) is rapidly rising in several Asian countries, including Malaysia, but there is little data on health care provider costs in this region. The aim of this study was to estimate the cost of CRC management from the perspective of the health care provider, based on standard operating procedures. METHODS: A combination of top-down approach and activity-based costing was applied. The standard operating procedure (SOP) for CRC was developed for each stage according to national data and guidelines at the University of Malaya Medical Centre (UMMC). The unit cost was calculated and incorporated into the treatment pathway in order to obtain the total cost of managing a single CRC patient according to the stage of illness. The cost data were represented by means and standard deviation and the results were demonstrated by tabulation. All cost data are presented in Malaysian Ringgit (RM). The cost difference between early stage (Stage I) and late stage (Stage II-IV) was analysed using independent t-test. RESULTS: The cost per patient increased with stage of CRC, from RM13,672 (USD4,410.30) for stage I, to RM27,972 (USD9,023.20) for Stage IV. The early stage had statistically significant lower cost compared to late stage t(2) = -4.729, P = 0.042. The highest fraction of the cost was related to surgery for Stage I, but was superseded by oncology day care treatment for Stages II-IV. CRC is a costly illness. From a provider perspective, the highest cost was found in Stages III and IV. The early stages conserved more resources than did the advanced stages of cancer. CONCLUSION: Early diagnosis and management of CRC, therefore, not only affects oncologic prognosis, but has implications for health care costs. This adds further justification to develop and implement CRC screening programmes in Malaysia.

The 'Be Cancer Alert Campaign': protocol to evaluate a mass media campaign to raise awareness about breast and colorectal cancer in Malaysia.

BACKGROUND: Breast and colorectal cancer are the two most common cancers in Malaysia. Low awareness coupled with stigma and erroneous beliefs delay help-seeking behaviours, lead to late presentation and contribute to poor detection rates. Promoting cancer awareness through mass media may be effective in improving cancer-related knowledge and uptake in screening tests. However, research is sparse regarding the cultural translation and implementation of mass media campaigns in Malaysia (and Asia) in terms of raising awareness about colorectal and breast cancer. METHODS: A collaborative partnership comprising researchers from Malaysia and the UK as well as policy makers, public health experts and non-government organisations from Malaysia was formed to design, deliver and evaluate the Be Cancer Alert Campaign. Each awareness-raising campaign will run for five weeks (Colorectal Cancer in April 2018, followed by Breast Cancer in October 2018). Evaluation of the campaigns will take place in Gombak district (Colorectal Cancer) and Petaling district (Breast Cancer) respectively, in the form of a pre-post randomly selected household survey and collection of service utilisation data. Occupants who are aged 40-years and above and are able to answer questions independently will be selected from each household. A sample of 730 with 80% power will detect a change of 6.09% in knowledge that unexplained lump or swelling is a symptom of breast cancer or changes in bowel habits is a symptom of colorectal cancer. DISCUSSION: Malaysia and most South-East Asian countries have a low middle-income economy, with limited resources for cancer control. Late-staged cancers impose a significant economic burden on patients, households, communities, employers, health systems and governments. Our proposed strategy for the implementation of the culturally sensitive mass media cancer awareness-raising campaign will serve as a blueprint for cancer prevention and control policy in South-East Asian countries where the burden of cancer is increasing and there are high cancer death rates.

Evaluating the quality of antenatal care and pregnancy outcomes using content and utilization assessment.

OBJECTIVE: To assess the adequacy of antenatal care (ANC) and its association with pregnancy outcomes using an approach that includes adequacy of both utilization and content. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Women attending ANC at public-funded primary health clinics where data were extracted from individual records. METHODS: Adequacy of utilization assessment was based on the concept of Adequacy of Prenatal Care Utilization index; adequacy of content assessed the recommended routine care received by the women according to local guidelines. Association between adequacy and pregnancy outcomes was examined using binary logistic regression. MAIN OUTCOME MEASURES: Pregnancy outcomes included preterm birth and low birth weight. RESULTS: Sixty-three percent of women showed higher than recommended ANC utilization; 52% had <80% of recommended routine care content. Although not statistically significant, the odds of preterm birth was lower among women with adequate level of utilization compared with inadequate (adjusted odds ratios (aOR) = 2.34, 95% confidence interval (CI) 0.45-12.16) and intensive levels (aOR = 3.27, 95% CI 0.73-14.60). Regarding adequacy of content, women who received inadequate level of care content were associated with higher prevalence of preterm birth (aOR = 3.69, 95% CI 1.60-8.55). CONCLUSION: The study shows inadequate content is associated with higher prevalence of preterm birth and suggests that inadequate utilization increases the risk of preterm birth. It demonstrates the relevance of using both utilization and content assessment in evaluating quality of ANC. Further studies are encouraged to review the methods used.

Correction to: The effectiveness of a life style modification and peer support home blood pressure monitoring in control of hypertension: protocol for a cluster randomized controlled trial.

After publication of the article [1], it has been brought to our attention that the methodology outlined in the original article was not able to be fully carried out. The article planned a two armed randomized control trial. However, due to a lower response than expected and one housing complex dropping out from the study, the method was changed to pre- and post-intervention with no control group. All other methods were conducted as outlined in the original article.

Issues in healthcare services in Malaysia as experienced by Japanese retirees.

BACKGROUND: Worldwide, international retirement migration is growing in its popularity and Japanese retirees choose Malaysia as their most preferred destination. This study examines the pertinent issues related to healthcare services as experienced by Japanese retirees in this country. METHODS AND RESULTS: From January to March 2015, we conducted focus group discussions with 30 Japanese retirees who live in Kuala Lumpur and Ipoh. Guided by the social-ecological model, we discovered seven pertinent themes: 'language barriers','healthcare decisions', 'medical check-ups','healthcare insurance', 'nursing and palliative care', 'trust and distrust of healthcare services', and 'word-of-mouth information'. DISCUSSION: We identified seven pertinent issues related to healthcare services among Japanese retirees in Malaysia, of which four are especially important. These issues are explained as integrated themes within the social-ecological model. Language barriers prohibit them from having difficulty accessing to healthcare in Malaysia, but lack of will to improve their language skills exist among them. For that reason, they rely heavily on word-of-mouth information when seeking for healthcare. As a consequence, some develop feelings of trust and distrust of healthcare services. In addition, we have identified the needs for provide nursing and palliative care among Japanese retirees in Malaysia. CONCLUSION: Based on the magnitude of the discussion, we concluded that there are four crucial healthcare issues among Japanese retirees; 'language barriers', 'trust and distrust of healthcare services', 'word-of-mouth information' and 'nursing and palliative care'. We propose that further dialogue by healthcare stakeholders should be carried out to improve further the healthcare service provisions for Japanese retirees in Malaysia.

Anxiety, depression, perceived social support and quality of life in Malaysian breast cancer patients: a 1-year prospective study.

BACKGROUND: Depression and anxiety are common psychiatric morbidity among breast cancer patient. There is a lack of study examining the correlation between depression, anxiety and quality of life (QoL) with perceived social support (PSS) among breast cancer patients. This study aims to study the level of depression, anxiety, QoL and PSS among Malaysian breast cancer women over a period of 12 months and their associations at baseline, 6 and 12 months. METHODS: It is a 12 months prospective cohort study. Two hundred and twenty one female patients were included in the study. They were assessed at the time of diagnosis, 6 months and 12 month using Hospital Anxiety and Depression Scale (HADS), Quality-of-Life Questionnaire (QLQ-C30), Version 3.0 of the EORTC Study Group and Multidimensional Scale of Perceived Social Support (MSPSS). The information of age, ethnicity, types of treatment, and staging of cancer were collected. RESULTS: The HADS anxiety and depression subscales scores of the subjects were relatively low. The level of anxiety reduced significantly at 6 and 12 months (Baseline - 6 months, p = 0.002; Baseline - 12 months, p < 0.001). There were no changes in the level of depression over the study period. The global status of QoL and MSPSS scores were relatively high. Correlation between the global status of QoL and MSPSS for the study subjects was positive (Spearman's rho = 0.31-0.36). Global status of QoL and MSPSS scores were negatively correlated with anxiety and depression. CONCLUSION: Malaysian breast cancer women had relatively better QoL with lower level of anxiety and depression. Perceived social support was an important factor for better QoL and low level of psychological distress. It reflects the importance of attention on activities that enhance and maintain the social support system for breast cancer patients.

Anticipating rotavirus vaccines--a pre-vaccine assessment of incidence and economic burden of rotavirus hospitalizations among children < 5 year of age in Libya, 2012-13.

BACKGROUND: Libya introduced rotavirus vaccine in October 2013. We examined pre-vaccine incidence of rotavirus hospitalizations and associated economic burden among children < 5 years in Libya to provide baseline data for future vaccine impact evaluations. METHODS: Prospective, hospital-based active surveillance for rotavirus was conducted at three public hospitals in two cities during August 2012 - April 2013. Clinical, demographic and estimated cost data were collected from children <5 hospitalized for diarrhea; stool specimens were tested for rotavirus with a commercial enzyme immunoassay. Annual rotavirus hospitalization incidence rate estimates included a conservative estimate based on the number of cases recorded during the nine months and an extrapolation to estimate 12 months incidence rate. National rotavirus disease and economic burden were estimated by extrapolating incidence and cost data to the national population of children aged < 5 years. RESULTS: A total of 410 children < 5 years of age with diarrhea were enrolled, of whom 239 (58%) tested positive rotavirus, yielding an incidence range of 418-557 rotavirus hospitalizations per 100,000 children < 5 years of age. Most (86%) rotavirus cases were below two years of age with a distinct seasonal peak in winter (December-March) months. The total cost of treatment for each rotavirus patient was estimated at US$ 679 (range: 200-5,423). By extrapolation, we estimated 2,948 rotavirus hospitalizations occur each year in Libyan children < 5 years of age, incurring total costs of US$ 2,001,662 (range: 1,931,726-2,094,005). CONCLUSIONS: Rotavirus incurs substantial morbidity and economic burden in Libya, highlighting the potential value of vaccination of Libyan children against rotavirus.

Bridging the data gaps in the epidemiology of hepatitis C virus infection in Malaysia using multi-parameter evidence synthesis.

BACKGROUND: Collecting adequate information on key epidemiological indicators is a prerequisite to informing a public health response to reduce the impact of hepatitis C virus (HCV) infection in Malaysia. Our goal was to overcome the acute data shortage typical of low/middle income countries using statistical modelling to estimate the national HCV prevalence and the distribution over transmission pathways as of the end of 2009. METHODS: Multi-parameter evidence synthesis methods were applied to combine all available relevant data sources - both direct and indirect - that inform the epidemiological parameters of interest. RESULTS: An estimated 454,000 (95% credible interval [CrI]: 392,000 to 535,000) HCV antibody-positive individuals were living in Malaysia in 2009; this represents 2.5% (95% CrI: 2.2-3.0%) of the population aged 15-64 years. Among males of Malay ethnicity, for 77% (95% CrI: 69-85%) the route of probable transmission was active or a previous history of injecting drugs. The corresponding proportions were smaller for male Chinese and Indian/other ethnic groups (40% and 71%, respectively). The estimated prevalence in females of all ethnicities was 1% (95% CrI: 0.6 to 1.4%); 92% (95% CrI: 88 to 95%) of infections were attributable to non-drug injecting routes of transmission. CONCLUSIONS: The prevalent number of persons living with HCV infection in Malaysia is estimated to be very high. Low/middle income countries often lack a comprehensive evidence base; however, evidence synthesis methods can assist in filling the data gaps required for the development of effective policy to address the future public health and economic burden due to HCV.

Factors associated with return to work of breast cancer survivors: a systematic review.

BACKGROUND: The breast cancer survival rate is the highest among all types of cancers, and survivors returning to work after completing treatment is extremely important in regards to economy and rehabilitation. The aim of this systematic review study is to identify the prevalence of breast cancer survivors who return to work (RTW) and the factors associated to RTW. METHODS: A computer based literature search was carried out. "PubMed, Cochrane Library, Embase, Web of Science, and Science Direct" databases were searched systematically. Our search strategy identified a total of 12,116 papers of which 26 studies met the inclusion criteria and quality assessment. These were original papers published between January 2003 and January 2013. RESULTS: The trends in RTW differ among countries for the breast cancer survivors. The time to RTW after successful cancer treatment also varies among the countries and by ethnicity. The prevalence of the RTW varies from 43% to 93% within one year of diagnosis. The prevalence of the RTW for the Netherland is the lowest in the world (43%). The United States survivors showed the highest RTW (93%) within 12 months of the diagnosis. Numerous barriers and facilitators were identified as factors that affect RTW. For instance, socio-demographic factors such as education and ethnicity; treatment oriented factors such as chemotherapy; work related factors such as heavy physical work; disease related factors such as poor health condition and fatigue; and psychological factors such as depression and emotional distress, act as barriers of RTW. In contrast, social, family, employer support, and financial independency emerge as key facilitators in enabling breast cancer survivors to return and continue work. CONCLUSION: Minimising these identified barriers and strengthening these facilitators could further improve the work condition and increase the percentage of RTW among the breast cancer survivors.

Predictors of sexual risk behaviour among adolescents from welfare institutions in Malaysia: a cross sectional study.

BACKGROUND: In welfare institutions, it is essential to address the health-related needs of adolescent populations who often engage in sexual activities. This study examines the association between individual and interpersonal factors concerning sexual risk behaviour (SRB) among adolescents in welfare institutions in Malaysia. METHODS: Data were derived from a cross-sectional study of 1082 adolescents in 22 welfare institutions located across Peninsular Malaysia in 2009. Using supervised self-administered questionnaires, adolescents were asked to assess their self-esteem and to complete questions on pubertal onset, substance use, family structure, family connectedness, parental monitoring, and peer pressure. SRB was measured through scoring of five items: sexual initiation, age of sexual debut, number of sexual partners, condom use, and sex with high-risk partners. Multivariate logistic regression analysis was used to examine the various predictors of sexual risk behaviour. RESULTS: The study showed that 55.1% (95%CI = 52.0-58.2) of the total sample was observed to practice sexual risk behaviours. Smoking was the strongest predictor of SRB among male adolescents (OR = 10.3, 95%CI = 1.25-83.9). Among females, high family connectedness (OR = 3.13, 95%CI = 1.64-5.95) seemed to predict the behaviour. CONCLUSION: There were clear gender differences in predicting SRB. Thus, a gender-specific sexual and reproductive health intervention for institutionalised adolescents is recommended.
