    BMJ Open, 2023 Nov 21;13(11):e071087.
    PMID: 37989390 DOI: 10.1136/bmjopen-2022-071087
    OBJECTIVE: To explore patients' experiences accessing healthcare for obesity and their perceived behaviour changes following the care.

    DESIGN: Using a descriptive qualitative research approach informed by Levesque's framework of access to healthcare, we conducted phone interviews in the Malaysian language, which were audio-recorded and transcribed verbatim. Data were analysed inductively using a reflexive thematic analysis approach.

    SETTING: Primary care clinics in five states in Peninsular Malaysia.

    PARTICIPANTS: Adult patients with obesity receiving face-to-face care for obesity from healthcare providers in Peninsular Malaysia.

    RESULTS: We interviewed 22 participants aged 24-62, with the majority being female (77%), Malay (95%), married (73%) and with tertiary education (82%). Most participants attended obesity management services at public primary care clinics. We identified five themes: (1) moving from perceiving the need to seeking obesity care is a non-linear process for patients, (2) providers' words can inspire patients to change, (3) patients' needs and preferences are not adequately addressed in current obesity care, (4) over-focusing on weight by patients and healthcare providers can lead to self-blame and loss of hope for patients and (5) obesity healthcare can have consequences beyond weight loss.

    CONCLUSION: Patients lack the self-regulatory skills to continue their lifestyle changes and struggle with self-blame and hopelessness. Over-focusing on weight by patients and obesity healthcare increase patients' self-stigmatisation. While provider-initiated weight discussions and engaging and personalised consultation provide the initial step towards weight management, obesity healthcare could be enhanced by behavioural support and patient education on the complexity of obesity. Further considerations could be given to shifting from a weight-centric to a more holistic health-centred approach in obesity healthcare.

    INTRODUCTION: Patient-centred infertility care (PCIC) is one of the quality indicators of effective fertility care. The application of this indicator requires a clear definition from the patient's perspective. This proposed scoping review aims to explore the extent and nature of published scientific literature on PCIC in the past decade, identify gaps in the literature and define PCIC from infertile patients' perspectives.

    METHODS AND ANALYSIS: We will conduct the proposed scoping review following the method of Arksey and O'Malley. The literature search will include studies published from 2009 to 2019, and will be conducted on the MEDLINE, PsycINFO, Scopus, Cochrane Library, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases; reference lists will be mined for literature not contained on these databases. A grey literature search will also be conducted. To be included in the review, studies should have been conducted on people with a history of infertility, with a focus on patient-centred fertility care. Studies that have not been published in full text and studies published in languages other than English will be excluded. After study selection, data will be charted in a prepared form. We will analyse the data using descriptive numerical and qualitative thematic analyses to answer the research questions. NVivo V.12 will be used for data extraction.

    ETHICS AND DISSEMINATION: This work does not warrant any ethical or safety concerns. This scoping review will synthesise existing literature on PCIC, and the results will be published to be readily available for clinical audiences and policymakers. These findings may support clinicians and decision-makers in applying PCIC, thereby promoting high-quality healthcare in the concerned population.

    OBJECTIVE: The current study aims to define patient-centred infertility care (PCIC) from the perspective of Arab women with infertility.

    DESIGN: Semistructured in-depth telephone interviews.

    SETTING: Hospitals providing infertility care, Jeddah, Saudi Arabia.

    PARTICIPANTS: Arab women who received infertility treatment during the 6 months preceding the interview at any hospital in Jeddah, Saudi Arabia. Interviews were conducted with Arab women experiencing infertility from January 2017 to December 2018. A purposive sample of 14 women were included in the final analysis with maximum variation.

    RESULTS: Participants highlighted nine important PCIC dimensions. Of these, four were agreed on by all participants: accessibility, minimising cost, information and education, and staff attitudes and communication. The remaining five dimensions were staff competence, physical comfort, privacy, psychological and emotional support, and continuity and coordination of care. The concept of PCIC was related to three major contributors: participants' demographics, patient experience with infertility care and health-seeking behaviour.

    CONCLUSIONS: The current study provided nine PCIC dimensions and items, which can guide efforts to improve the quality of infertility care in Arab countries in two ways: first, by raising infertility care providers' awareness of their patients' needs, and second, by developing a validated tool based on the dimensions for measuring PCIC from Arab patients' perspective. Clear differences between the Arab and the European PCIC model were found. Our findings concluded that women continued to exhibit basic unmet needs.

    OBJECTIVE: Shared decision-making has been advocated as a useful model for patient management. In developing Asian countries such as Malaysia, there is a common belief that patients prefer a passive role in clinical consultation. As such, the objective of this study was to determine Malaysian patients' role preference in decision-making and the associated factors.
    DESIGN: A cross-sectional study.
    SETTING: Study was conducted at an urban primary care clinic in Malaysia in 2012.
    PARTICIPANTS: Patients aged >21 years were chosen using systematic random sampling.
    METHODS: Consenting patients answered a self-administered questionnaire, which included demographic data and their preferred and actual role before and after consultation. Doctors were asked to determine patients' role preference. The Control Preference Scale was used to assess patients' role preference.
    PRIMARY OUTCOME: Prevalence of patients' preferred role in decision-making.
    SECONDARY OUTCOMES: (1) Actual role played by the patient in decision-making. (2) Sociodemographic factors associated with patients' preferred role in decision-making. (3) Doctors' perception of patients' involvement in decision-making.
    RESULTS: The response rate was 95.1% (470/494). Shared decision-making was preferred by 51.9% of patients, followed by passive (26.3%) and active (21.8%) roles in decision-making. Higher household income was significantly associated with autonomous role preference (p=0.018). Doctors' perception did not concur with patients' preferred role. Among patients whom doctors perceived to prefer a passive role, 73.5% preferred an autonomous role (p=0.900, κ=0.006).
    CONCLUSIONS: The majority of patients attending the primary care clinic preferred and played an autonomous role in decision-making. Doctors underestimated patients' preference to play an autonomous role.

    INTRODUCTION: Growing evidence suggesting that dietary intakes of adolescents are generally of poor quality but not adequately assessed in relation to the early manifestation of non-communicable diseases. This study aimed; (1) to examine tracking of an empirical dietary pattern (DP) linked to cardiometabolic risk factors and, (2) to assess prospective relationships between a DP characterised by high intakes of dietary energy density (DED) and added sugar, and cardiometabolic risk factors, non-alcoholic fatty liver disease (NAFLD), carotid intima-medial thickness (CIMT) and mental well-being during adolescence.

    METHODS AND ANALYSIS: The PUTRA-Adol is a prospective follow-up study that builds up from 933 Malaysian adolescents who were initially recruited from three southern states in Peninsular Malaysia in 2016 (aged 13 years then). Two sessions are planned; the first session will involve the collection of socio-economy, physical activity, dietary intakes, mental well-being, body image, risk taking behaviour, sun exposure, family functioning and menstrual (in women) information. The second session of data collection will be focused on direct assessments such as venesection for blood biochemistry, anthropometry and ultrasonography imaging of liver and bilateral carotid arteries. Z-scores for an empirical DP will be identified at 16 years using reduced rank regression. Multilevel modelling will be conducted to assess the tracking of DP and prospective analysis between the DP, cardiometabolic health, NAFLD, CIMT and mental well-being.

    ETHICS AND DISSEMINATION: Ethical approval for the conduct of this follow-up study was obtained from the Universiti Putra Malaysia's Ethics Committee for Research Involving Human Subjects (JKEUPM) (Reference number: JKEUPM-2019-267). The findings from this study will be disseminated in conferences and peer-reviewed journals.

    DISCUSSION: The findings gathered from this study will provide evidence on prospective relationships between DPs, cardiometabolic risk factors, NAFLD, early atherosclerosis and mental well-being and that it may be mediated particularly DED and added sugar during adolescence.

    PMID: 29705765 DOI: 10.1136/bmjopen-2017-020841
    INTRODUCTION: Current evidence on epidemiology and outcomes of invasively mechanically ventilated intensive care unit (ICU) patients is predominantly gathered in resource-rich settings. Patient casemix and patterns of critical illnesses, and probably also ventilation practices are likely to be different in resource-limited settings. We aim to investigate the epidemiological characteristics, ventilation practices and clinical outcomes of patients receiving mechanical ventilation in ICUs in Asia.

    METHODS AND ANALYSIS: PRoVENT-iMIC (study of PRactice of VENTilation in Middle-Income Countries) is an international multicentre observational study to be undertaken in approximately 60 ICUs in 11 Asian countries. Consecutive patients aged 18 years or older who are receiving invasive ventilation in participating ICUs during a predefined 28-day period are to be enrolled, with a daily follow-up of 7 days. The primary outcome is ventilatory management (including tidal volume expressed as mL/kg predicted body weight and positive end-expiratory pressure expressed as cm H2O) during the first 3 days of mechanical ventilation-compared between patients at no risk for acute respiratory distress syndrome (ARDS), patients at risk for ARDS and in patients with ARDS (in case the diagnosis of ARDS can be made on admission). Secondary outcomes include occurrence of pulmonary complications and all-cause ICU mortality.

    ETHICS AND DISSEMINATION: PRoVENT-iMIC will be the first international study that prospectively assesses ventilation practices, outcomes and epidemiology of invasively ventilated patients in ICUs in Asia. The results of this large study, to be disseminated through conference presentations and publications in international peer-reviewed journals, are of ultimate importance when designing trials of invasive ventilation in resource-limited ICUs. Access to source data will be made available through national or international anonymised datasets on request and after agreement of the PRoVENT-iMIC steering committee.

    INTRODUCTION: Private sector provision of HIV treatment is increasing in low-income and middle-income countries (LMIC). However, there is limited documentation of its outcomes. This protocol reports a proposed systematic review that will synthesise clinical outcomes of private sector HIV treatment in LMIC.

    METHODS AND ANALYSIS: This review will be conducted in accordance with the preferred reporting items for systematic review and meta-analyses protocols. Primary outcomes will include: (1) proportion of eligible patients initiating antiretroviral therapy (ART); (2) proportion of those on ART with <1000 copies/mL; (3) rate of all-cause mortality among ART recipients. Secondary outcomes will include: (1) proportion receiving Pneumocystis jiroveci pneumonia prophylaxis; (2) proportion with >90% ART adherence (based on any measure reported); (3) proportion screened for non-communicable diseases (specifically cervical cancer, diabetes, hypertension and mental ill health); (iv) proportion screened for tuberculosis. A search of five electronic bibliographical databases (Embase, Medline, PsychINFO, Web of Science and CINAHL) and reference lists of included articles will be conducted to identify relevant articles reporting HIV clinical outcomes. Searches will be limited to LMIC. No age, publication date, study-design or language limits will be applied. Authors of relevant studies will be contacted for clarification. Two reviewers will independently screen citations and abstracts, identify full text articles for inclusion, extract data and appraise the quality and bias of included studies. Outcome data will be pooled to generate aggregative proportions of primary and secondary outcomes. Descriptive statistics and a narrative synthesis will be presented. Heterogeneity and sensitivity assessments will be conducted to aid interpretation of results.

    ETHICS AND DISSEMINATION: The results of this review will be disseminated through a peer-reviewed scientific manuscript and at international scientific conferences. Results will inform quality improvement strategies, replication of identified good practices, potential policy changes, and future research.

    PMID: 25001396 DOI: 10.1136/bmjopen-2014-005381
    OBJECTIVE: To investigate factors associated with demographic/clinical characteristics and drug selection in patients with erectile dysfunction (ED). The prevalence of ED is increasing worldwide. Studies have shown that ED is associated with age, lifestyle and comorbidities. However, the factors associated with patient characteristics as well as drug selection are incompletely understood.

    SETTING: A tertiary medical centre in Kuala Lumpur, Malaysia.

    PARTICIPANTS: A total of 219 patients (range 23-80 years) who had received phosphodiesterase type-5 (PDE-5) inhibitors as ED treatment were evaluated.

    INCLUSION CRITERIA: Adult patients aged ≥18 years, diagnosed with ED, and prescribed with sildenafil, tadalafil or vardenafil.

    EXCLUSION CRITERIA: Patients diagnosed with ED but who did not receive any PDE-5 inhibitor, or those with missing data.

    PRIMARY AND SECONDARY OUTCOME MEASURES: Factors associated with demographic and clinical characteristics as well as drug selection were assessed.

    RESULTS: Ischaemic heart disease (p=0.025), benign prostatic hyperplasia (p<0.001), obesity (p=0.005), lower urinary tract symptoms (LUTS) (p=0.006) and α-blockers (p<0.001) were significantly associated with elderly patients with ED. Additionally, LUTS (p=0.038) and α-blockers (p=0.008) were significantly associated with the selection of PDE-5 inhibitor.

    CONCLUSIONS: These data showed that elderly patients with ED were significantly associated with comorbidities and α-blockers, whereas LUTS and α blockers were associated with drug selection.

    INTRODUCTION: Orientation and mobility (O&M) specialists assess the functional vision and O&M skills of people with mobility problems, usually relating to low vision or blindness. There are numerous O&M assessment checklists but no measures that reduce qualitative assessment data to a single comparable score suitable for assessing any O&M client, of any age or ability, in any location. Functional measures are needed internationally to align O&M assessment practices, guide referrals, profile O&M clients, plan appropriate services and evaluate outcomes from O&M programmes (eg, long cane training), assistive technology (eg, hazard sensors) and medical interventions (eg, retinal implants). This study aims to validate two new measures of functional performance vision-related outcomes in orientation and mobility (VROOM) and orientation and mobility outcomes (OMO) in the context of ordinary O&M assessments in Australia, with cultural comparisons in Malaysia, also developing phone apps and online training to streamline professional assessment practices.

    METHODS AND ANALYSIS: This multiphase observational study will employ embedded mixed methods with a qualitative/quantitative priority: corating functional vision and O&M during social inquiry. Australian O&M agencies (n=15) provide the sampling frame. O&M specialists will use quota sampling to generate cross-sectional assessment data (n=400) before investigating selected cohorts in outcome studies. Cultural relevance of the VROOM and OMO tools will be investigated in Malaysia, where the tools will inform the design of assistive devices and evaluate prototypes. Exploratory and confirmatory factor analysis, Rasch modelling, cluster analysis and analysis of variance will be undertaken along with descriptive analysis of measurement data. Qualitative findings will be used to interpret VROOM and OMO scores, filter statistically significant results, warrant their generalisability and identify additional relevant constructs that could also be measured.

    ETHICS AND DISSEMINATION: Ethical approval has been granted by the Human Research Ethics Committee at Swinburne University (SHR Project 2016/316). Dissemination of results will be via agency reports, journal articles and conference presentations.

    OBJECTIVE: Thalassaemia is the most common inherited blood disorder in Malaysia. This study aims to report the current status of thalassaemia in Malaysia and provide a comprehensive understanding of the disease through data obtained from the Malaysian Thalassaemia Registry.

    DESIGN: Data were extracted from the Malaysian Thalassaemia Registry, a web-based system accessible to enrolled users through www.mytalasemia.net.my.

    SETTING: The Malaysian Thalassaemia Registry data was recorded from reports obtained from 110 participating government and university hospitals in Malaysia.

    PARTICIPANTS: The patients were those attending the 110 participating hospitals for thalassaemia treatment.

    INTERVENTION: Data were collected from the Malaysian Thalassaemia Registry from 2007 until the fourth quarter of 2018.

    PRIMARY OUTCOME MEASURE: 7984 out of 8681 patients with thalassaemia registered in the Malaysian Thalassaemia Registry were reported alive.

    RESULTS: Majority of the patients were reported in the state of Sabah (22.72%); the largest age group affected was 5.0-24.9 years old (64.45%); the largest ethnic group involved was Malay (63.95%); and the major diagnosis was haemoglobin E/β-thalassaemia (34.37%). From the 7984 patients, 56.73% were on regular blood transfusions and 61.72% were on chelation therapy. A small fraction (14.23%) has undergone splenectomy, while the percentage of patients with severe iron overload (serum ferritin ≥5000 µg/L) reduced over time. However, cardiac complications are still the main cause of death in patients with thalassaemia.

    CONCLUSION: Data gathered into the registry can be used to understand the progression of the disorder, to monitor iron overload management and to improve the outcomes of treatment, to enhance preventive strategies, reduce healthcare burden and improve the quality of life. Sustainability of the Malaysian Thalassaemia Registry is important for surveillance of thalassaemia management in the country and help the national health authorities to develop more effective policies.

    OBJECTIVES: To determine the prevalence of metabolic syndrome (MS), ascertain the status of coronary risk biomarkers and establish the independent predictors of these biomarkers among the Negritos.

    SETTINGS: Health screening programme conducted in three inland settlements in the east coast of Malaysia and Peninsular Malaysia.

    SUBJECTS: 150 Negritos who were still living in three inland settlements in the east coast of Malaysia and 1227 Malays in Peninsular Malaysia. These subjects were then categorised into MS and non-MS groups based on the International Diabetes Federation (IDF) consensus worldwide definition of MS and were recruited between 2010 and 2015. The subjects were randomly selected and on a voluntary basis.

    PRIMARY AND SECONDARY OUTCOME MEASURES: This study was a cross-sectional study. Serum samples were collected for analysis of inflammatory (hsCRP), endothelial activation (sICAM-1) and prothrombogenesis [lp(a)] biomarkers.

    RESULTS: MS was significantly higher among the Malays compared with Negritos (27.7%vs12.0%). Among the Malays, MS subjects had higher hsCRP (p=0.01) and sICAM-1 (p<0.05) than their non-MS counterpart. There were no significant differences in all the biomarkers between MS and the non-MS Negritos. However, when compared between ethnicity, all biomarkers were higher in Negritos compared with Malays (p<0.001). Binary logistic regression analysis affirmed that Negritos were an independent predictor for Lp(a) concentration (p<0.001).

    CONCLUSIONS: This study suggests that there may possibly be a genetic influence other than lifestyle, which could explain the lack of difference in biomarkers concentration between MS and non-MS Negritos and for Negritos predicting Lp(a).

    OBJECTIVE: To identify the prevalence of stage B heart failure (SBHF) in patients with type 2 diabetes mellitus (T2DM) with no history of cardiovascular disease (CVD).

    DESIGN: Observational study.

    SETTING: A single-centre study in which eligible patients were recruited from T2DM clinic. Following consent, patients completed a questionnaire and underwent physical examinations. Patients had blood drawn for laboratory investigations and had a transthoracic echocardiography.

    PARTICIPANTS: A total of 305 patients who were not known to have CVD were recruited. Patients with deranged liver function tests and end stage renal failure were excluded.

    MAIN OUTCOME MEASURES: Echocardiographic parameters such as left ventricular ejection fraction, left ventricular mass index (LVMI), left ventricular hypertrophy, left atrial enlargement and diastolic function were examined.

    RESULTS: A total of 305 patients predominantly females (65%), with mean body mass index of 27.5 kg/m2 participated in this study. None of them had either a history or signs and symptoms of CVD. Seventy-seven percent of patients had a history of hypertension and 83% of this study population had T2DM for more than 10 years. Mean HbA1c of 8.3% was recorded. Almost all patients were taking metformin. Approximately, 40% of patients were on newer anti-T2DM agents such as sodium-glucose cotransporter-2 and dipeptidyl peptidase 4 inhibitors. Fifty-seven percent (n=174) of the study population had SBHF at the time of study: diastolic dysfunction, increased LVMI and increased left atrial volume index (LAVI) were noted in 51 patients (17%), 128 patients (42%) and 98 patients (32%), respectively. Thirty-seven patients (12%) had both increase LVMI and LAVI.

    CONCLUSION: Our study has revealed a high prevalence of SBHF in T2DM patients without overt cardiac disease in Malaysia that has one of the highest prevalence of TDM in the world.

    INTRODUCTION: An ageing population has become an urgent concern for Asia in recent times. In nursing homes, polypharmacy has also become a compounding issue. Deprescribing practice is an evidence-based strategy to provide a better outcome in this group of patients; however, its implementation in nursing homes is often challenging, and prospective outcome data on deprescribing practice in the elderly is lacking. Our study assesses the implementation of team-care deprescribing to understand the benefits of this practice in geriatric setting and to explore the factors affecting deprescribing practice.

    METHODS AND ANALYSIS: This multicentre prospective study consists of a prestudy interview questionnaire, and a preintervention and postintervention study to be conducted in the nursing home setting on residents at least 65 years old and on five or more medications. We will employ a cluster randomised stepped-wedge interventional design, based on a five-step (reviewing, checking, discussion, communication and documentation) team-care deprescribing practice coupled with the use of a deprescribing guide (consisting of Beers and STOPP criteria, as well as drug interaction checking), to assess the health and pharmacoeconomic outcome in nursing homes' practice. Primary outcome measures of the intervention will consist of fall risks using a fall risk assessment tool. Other outcomes assessed include fall rates, pill burden including number of pills per day, number of doses per day and number of medications prescribed. Cost-related measures will include the use of cost-benefit analysis, which is calculated from the medication cost savings from deprescribing. For the prestudy interview questionnaire, findings will be analysed qualitatively using thematic analysis.

    ETHICS AND DISSEMINATION: This study is approved by the Domain Specific Review Board of National Healthcare Group, Singapore (2016/00422) and Monash University Human Research Ethics Committee (2016-1430-7791). The study findings shall be disseminated in international conferences and peer-reviewed publications. The study is registered with ClinicalTrials.gov (NCT02863341), Pre-results.

    PMID: 31005918 DOI: 10.1136/bmjopen-2018-025322
    OBJECTIVE: To determine the reproducibility of visit-to-visit blood pressure variability (BPV) in clinical practice. We also determined the minimum number of blood pressure (BP) measurements needed to estimate long-term visit-to-visit BPV for predicting 10-year cardiovascular (CV) risk.

    DESIGN: Retrospective study SETTING: A primary care clinic in a university hospital in Malaysia.

    PARTICIPANTS: Random sampling of 1403 patients aged 30 years and above without any CV event at baseline.

    OUTCOMES MEASURES: The effect of the number of BP measurement for calculation of long-term visit-to-visit BPV in predicting 10-year CV risk. CV events were defined as fatal and non-fatal coronary heart disease, fatal and non-fatal stroke, heart failure and peripheral vascular disease.

    RESULTS: The mean 10-year SD of systolic blood pressure (SBP) for this cohort was 13.8±3.5 mm Hg. The intraclass correlation coefficient (ICC) for the SD of SBP based on the first eight and second eight measurements was 0.38 (p<0.001). In a primary care setting, visit-to-visit BPV (SD of SBP calculated from 20 BP measurements) was significantly associated with CV events (adjusted OR 1.07, 95% CI 1.02 to 1.13, p=0.009). Using SD of SBP from 20 measurement as reference, SD of SBP from 6 measurements (median time 1.75 years) has high reliability (ICC 0.74, p<0.001), with a mean difference of 0.6 mm Hg. Hence, a minimum of six BP measurements is needed for reliably estimating intraindividual BPV for CV outcome prediction.

    CONCLUSION: Long-term visit-to-visit BPV is reproducible in clinical practice. We suggest a minimum of six BP measurements for calculation of intraindividual visit-to-visit BPV. The number and duration of BP readings to derive BPV should be taken into consideration in predicting long-term CV risk.

    PMID: 26201722 DOI: 10.1136/bmjopen-2015-007648
    OBJECTIVES: Single nucleotide polymorphism (SNP) with a mutation can be used to identify the presence of the paternally-inherited wild-type or mutant allele as result of the inheritance of either allele in the fetus and allows the prediction of the fetal genotype. This study aims to identify paternal SNPs located at the flanking regions upstream or downstream from the β-globin gene mutations at CD41/42 (HBB:c.127_130delCTTT), IVS1-5 (HBB:c.92+5G>C) and IVS2-654 (HBB:c.316-197C>T) using free-circulating fetal DNA.

    SETTING: Haematology Lab, Department of Biomedical Science, University of Malaya.

    PARTICIPANTS: Eight couples characterised as β-thalassaemia carriers where both partners posed the same β-globin gene mutations at CD41/42, IVS1-5 and IVS2-654, were recruited in this study.

    OUTCOME MEASURES: Genotyping was performed by allele specific-PCR and the locations of SNPs were identified after sequencing alignment.

    RESULTS: Genotype analysis revealed that at least one paternal SNP was present for each of the couples. Amplification on free-circulating DNA revealed that the paternal mutant allele of SNP was present in three fcDNA. Thus, the fetuses may be β-thalassaemia carriers or β-thalassaemia major. Paternal wild-type alleles of SNP were present in the remaining five fcDNA samples, thus indicating that the fetal genotypes would not be homozygous mutants.

    CONCLUSIONS: This preliminary research demonstrates that paternal allele of SNP can be used as a non-invasive prenatal diagnosis approach for at-risk couples to determine the β-thalassaemia status of the fetus.

    OBJECTIVE: Estimation of the net survival of breast cancer helps in assessing breast cancer burden at a population level. Thus, this study aims to estimate the net survival of breast cancer at different cancer staging and age at diagnosis in the east coast region of West Malaysia.

    SETTING: Kelantan, Malaysia.

    PARTICIPANTS: All breast cancer cases diagnosed in 2007 and 2011 identified from Kelantan Cancer Registry.

    DESIGN: This retrospective cohort study used a relative survival approach to estimate the net survival of patients with breast cancer. Thus, two data were needed; breast cancer data from Kelantan Cancer Registry and general population mortality data for Kelantan population.

    PRIMARY AND SECONDARY OUTCOME MEASURES: Net survival according to stage and age group at diagnosis at 1, 3 and 5 years following diagnosis.

    RESULTS: The highest net survival was observed among stage I and II breast cancer cases, while the lowest net survival was observed among stage IV breast cancer cases. In term of age at diagnosis, breast cancer cases aged 65 and older had the best net survival compared with the other age groups.

    CONCLUSION: The age at diagnosis had a minimal impact on the net survival compared with the stage at diagnosis. The finding of this study is applicable to other populations with similar breast cancer profile.

    INTRODUCTION: Middle East respiratory syndrome (MERS) is a viral respiratory infection caused by the MERS-CoV. MERS was first reported in the Kingdom of Saudi Arabia in 2012. Every year, the Hajj pilgrimage to Mecca attracts more than two million pilgrims from 184 countries, making it one of the largest annual religious mass gatherings (MGs) worldwide. MGs in confined areas with a high number of pilgrims' movements worldwide continues to elicit significant global public health concerns. MERCURIAL was designed by adopting a seroconversion surveillance approach to provide multiyear evidence of MG-associated MERS-CoV seroconversion among the Malaysian Hajj pilgrims.

    METHODS AND ANALYSIS: MERCURIAL is an ongoing multiyear prospective cohort study. Every year, for the next 5 years, a cohort of 1000 Hajj pilgrims was enrolled beginning in the 2016 Hajj pilgrimage season. Pre-Hajj and post-Hajj serum samples were obtained and serologically analysed for evidence of MERS-CoV seroconversion. Sociodemographic data, underlying medical conditions, symptoms experienced during Hajj pilgrimage, and exposure to camel and untreated camel products were recorded using structured pre-Hajj and post-Hajj questionnaires. The possible risk factors associated with the seroconversion data were analysed using univariate and multivariate logistic regression. The primary outcome of this study is to better enhance our understanding of the potential threat of MERS-CoV spreading through MG beyond the Middle East.

    ETHICS AND DISSEMINATION: This study has obtained ethical approval from the Medical Research and Ethics Committee (MREC), Ministry of Health Malaysia. Results from the study will be submitted for publication in peer-reviewed journals and presented in conferences and scientific meetings.

    TRIAL REGISTRATION NUMBER: NMRR-15-1640-25391.

    INTRODUCTION: Growing evidence suggests that climate change-related extreme weather events adversely impact maternal and child health (MCH) outcomes, which requires effective, sustainable and culturally appropriate interventions at individual, community and policy levels to minimise these impacts. This scoping review proposes to map the evidence available on the type, characteristics and outcomes of multilevel interventions implemented as adaptational strategies to protect MCH from the possible adverse effects of climate change.

    METHODS: The following databases will be searched: Embase, MEDLINE, Emcare, EPPI-Centre database of health promotion research (BiblioMap) EPPI-Centre Database for promoting Health Effectiveness Reviews (DoPHER), Global Health, CINAHL, Joanna Briggs Institute EBP Database, Maternity and Infant Care Database, Education Resource Information Center, PsycINFO, Scopus, Web of Science and Global Index Medicus, which indexes Latin America and the Caribbean, Index Medicus for the South-East Asia Region, African Index Medicus, Western Pacific Region Index Medicus. Cochrane Central Register of Controlled Trials, WHO International Clinical Trials Registry Platform, ClinicalTrials.gov, conference proceedings, thesis and dissertations, policy and guidelines and their reference lists will also be searched. Two reviewers will independently screen titles and abstracts and full text based on predefined eligibility criteria. The Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews using the Population, Concept and Context framework and the Template for Intervention Description and Replication checklist will be used to structure and report the findings.

    ETHICS AND DISSEMINATION: Ethics permission to conduct the scoping review is not required as the information collected is publicly available through databases. Findings will be disseminated through a peer-reviewed publication and conference presentations.

    INTRODUCTION: Proper assessment of unmet supportive care needs of patients with breast cancer and its influencing factors at different treatment intervals will improve the rehabilitation of patients with breast cancer. Therefore, this study aims to determine the prevalence of unmet supportive care needs, changes of needs over time and associated factors during the treatment period.

    METHODS AND ANALYSIS: This multicentre, prospective cohort study will be conducted in three governmental hospitals and one tertiary cancer institute in Penang, Malaysia. Adult women diagnosed with primary or recurrent tumour, node, metastases stage I-IV breast cancer based on pathological biopsy will be eligible for this study. At least 281 samples are required for this study. Participants will undergo follow-up at three time intervals: T1 at breast cancer diagnosis; T2 at 3 months after diagnosis and T3 at 6 months after diagnosis. Patients will complete a set of questionnaires at each time. The primary outcome of this study includes the changes in supportive care needs over three time points, followed by the secondary outcome examining patients' characteristics, coping behaviours and positive psychological components as they affect changes in unmet supportive care needs over time.

    ETHICS AND DISSEMINATION: The study has received ethics approval from the Medical Research and Ethics Committee, Ministry of Health Malaysia (NMRR-19-268-45809 IIR) and the Human Research Ethics Committee of Universiti Sains Malaysia (USM/JEPeM/17100443). The results of the prospective study will be submitted for publication in a peer-reviewed journal.
