IMPORTANCE: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data.
OBJECTIVE: To describe cancer burden for 29 cancer groups in 195 countries from 1990 through 2017 to provide data needed for cancer control planning.
EVIDENCE REVIEW: We used the GBD study estimation methods to describe cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life-years (DALYs). Results are presented at the national level as well as by Socio-demographic Index (SDI), a composite indicator of income, educational attainment, and total fertility rate. We also analyzed the influence of the epidemiological vs the demographic transition on cancer incidence.
FINDINGS: In 2017, there were 24.5 million incident cancer cases worldwide (16.8 million without nonmelanoma skin cancer [NMSC]) and 9.6 million cancer deaths. The majority of cancer DALYs came from years of life lost (97%), and only 3% came from years lived with disability. The odds of developing cancer were the lowest in the low SDI quintile (1 in 7) and the highest in the high SDI quintile (1 in 2) for both sexes. In 2017, the most common incident cancers in men were NMSC (4.3 million incident cases); tracheal, bronchus, and lung (TBL) cancer (1.5 million incident cases); and prostate cancer (1.3 million incident cases). The most common causes of cancer deaths and DALYs for men were TBL cancer (1.3 million deaths and 28.4 million DALYs), liver cancer (572 000 deaths and 15.2 million DALYs), and stomach cancer (542 000 deaths and 12.2 million DALYs). For women in 2017, the most common incident cancers were NMSC (3.3 million incident cases), breast cancer (1.9 million incident cases), and colorectal cancer (819 000 incident cases). The leading causes of cancer deaths and DALYs for women were breast cancer (601 000 deaths and 17.4 million DALYs), TBL cancer (596 000 deaths and 12.6 million DALYs), and colorectal cancer (414 000 deaths and 8.3 million DALYs).
CONCLUSIONS AND RELEVANCE: The national epidemiological profiles of cancer burden in the GBD study show large heterogeneities, which are a reflection of different exposures to risk factors, economic settings, lifestyles, and access to care and screening. The GBD study can be used by policy makers and other stakeholders to develop and improve national and local cancer control in order to achieve the global targets and improve equity in cancer care.

PMID: 32530926 DOI: 10.1371/journal.pone.0234350

Jackfruit-bronzing is caused by bacteria Pantoea stewartii subspecies stewartii (P. stewartii subsp. stewartii), showing symptoms of yellowish-orange to reddish discolouration and rusty specks on pulps and rags of jackfruit. Twenty-eight pure bacterial strains were collected from four different jackfruit outbreak collection areas in Peninsular Malaysia (Jenderam, Maran, Muadzam Shah and Ipoh). Positive P. stewartii subsp. stewartii verification obtained in the study was based on the phenotypic, hypersensitivity, pathogenicity and molecular tests. Multilocus sequence analysis (MLSA) was performed using four housekeeping genes (gyrB, rpoB, atpD and infB) on all 28 bacterial strains. Single gyrB, rpoB, atpD and infB phylogenetic trees analyses revealed the bootstrap value of 99-100% between our bacterial strains with P. stewartii subsp. stewartii reference strains and P. stewartii subsp. indologenes reference strains. On the other hand, phylogenetic tree of the concatenated sequences of the four housekeeping genes revealed that our 28 bacterial strains were more closely related to P. stewartii subsp. stewartii (99% similarities) compared to its close relative P. stewartii subsp. indologenes, although sequence similarity between these two subspecies were up to 100%. All the strains collected from the four collection areas clustered together, pointing to no variation among the bacterial strains. This study improves our understanding and provided new insight on the genetic diversity of P. stewartii subsp. stewartii associated with jackfruit-bronzing in Malaysia.

Am J Alzheimers Dis Other Demen, 2014 Aug;29(5):452-6.
PMID: 24408749 DOI: 10.1177/1533317513518654

INTRODUCTION: Given the high prevalence of dementia and its devastating consequences, identifying risk factors for dementia is a public health priority. The present study aims to assess whether gastritis increases the odds of dementia.
METHODOLOGY: The data for this study, consisting of 2926 community-dwelling older adults, were obtained from the National survey entitled "Mental Health and Quality of Life of Older Malaysians." Dementia was diagnosed using the Geriatric Mental State-Automated Geriatric Examination for Computer-Assisted Taxonomy.
RESULTS: Prevalence of dementia was considerably higher among older adults with gastritis (29.5%) compared to those without gastritis (13.2%). After adjusting for age, gender, marital status, educational attainment, hypertension, stroke, and diabetes, gastritis was significantly associated with more than twice odds of dementia (adjusted odds ratio = 2.42, P < .001, 95% confidence interval = 1.68-3.49).
CONCLUSIONS: The findings from this population-based observational study showing evidence that gastritis may increase the risk of dementia provide avenue for further inquiries into dementia.

Moghaddam SS, Jaafar HB, Aziz MA, Ibrahim R, Rahmat AB, Philip E

Molecules, 2011 Oct 25;16(11):8930-44.
PMID: 22027950 DOI: 10.3390/molecules16118930

The study was couducted to investigate the effects of gamma irradiation and CO₂ on flavonoid content and leaf gas exchange in C.asiatica. For flavonoid determination, the design was a split split plot based on Randomized Complete Block Design (RCBD). For other parameters, the designs were split plots. Statistical tests revealed significant differences in flavonoid contents of Centella asiatica leaves between different growth stages and various CO₂ treatments. CO₂ 400, G20 (400 = ambient CO₂; G20 = Plants exposed to 20 Gy) showed 82.90% higher total flavonoid content (TFC) in the 5th week than CO₂ 400 as control at its best harvest time (4th week). Increasing the concentration of CO₂ from 400 to 800 μmol/mol had significant effects on TFC and harvesting time. In fact, 800 μmol/mol resulted in 171.1% and 66.62% increases in TFC for control and irradiated plants, respectively. Moreover, increasing CO₂ concentration reduced the harvesting time to three and four weeks for control and irradiated plants, respectively. Enhancing CO₂ to 800 µmol/mol resulted in a 193.30% (CO₂ 800) increase in leaf biomass compared to 400 µmol/mol and 226.34% enhancement in irradiated plants (CO₂ 800, G20) [800 = Ambient CO₂; G20 = Plants exposed to 20 Gy] than CO₂ 400, G20. In addition, the CO₂ 800, G20 had the highest amount of flavonoid*biomass in the 4th week. The results of this study indicated that all elevated CO₂ treatments had higher PN than the ambient ones. The findings showed that when CO₂ level increased from 400 to 800 µmol/mol, stomatal conductance, leaf intercellular CO₂ and transpiration rate had the tendency to decrease. However, water use efficiency increased in response to elevated CO₂ concentration. Returning to the findings of this study, it is now possible to state that the proposed method (combined CO₂ and gamma irradiation) has the potential to increase the product value by reducing the time to harvest, increasing the yield per unit area via boosting photosynthesis capacity, as well as increasing biochemicals (flavonoids) per gram DM.

PMID: 37892411 DOI: 10.3390/nu15204335

To investigate the factors associated with sarcopenia in elderly individuals residing in nursing homes and community settings, we conducted a systematic search of databases, including MEDLINE, EMBASE, PubMed, Web of Science and Cochrane, up to May 2023. We incorporated a total of 70 studies into our analysis. Our findings revealed that the prevalence of sarcopenia in nursing homes ranged from 25% to 73.7%, while in community settings, it varied from 5.2% to 62.7%. The factors associated with sarcopenia in both nursing homes and community settings included male gender, BMI, malnutrition, and osteoarthritis. In community settings, these factors comprised age, poor nutrition status, small calf circumference, smoking, physical inactivity, cognitive impairment, diabetes, depression and heart disease. Currently, both the European Working Group on Sarcopenia in Older People (EWGSOP) and the Asian Working Group for Sarcopenia (AWGS) standards are widely utilized in nursing homes and community settings, with the EWGSOP standard being more applicable to nursing homes. Identifying factors associated with sarcopenia is of paramount significance, particularly considering that some of them can be modified and managed. Further research is warranted to investigate the impact of preventive measures on these factors in the management of sarcopenia among elderly individuals residing in nursing homes and community settings.

Emotional regulation as a mediator between the filial behaviour of the oldest son and subjective well-being of older parents in Pakistan

Hassan SMU, Hamid TA, Haron SA, Ibrahim R

Psychogeriatrics, 2020 Jan;20(1):59-69.
PMID: 31016831 DOI: 10.1111/psyg.12458

BACKGROUND: The link between the filial behaviour of an adult child and older parents' well-being is well entrenched, and theoretical evidence has indicated that it may be mediated by emotional regulation. Therefore, the current study aimed to examine whether emotional regulation (i.e. cognitive reappraisal and suppression) mediates the association between filial behaviour of the oldest son (i.e. the filial behaviour of respect and filial behaviour of daily maintenance) and subjective well-being in older parents.
METHODS: This correlational study recruited 400 community-dwelling older parents in Rawalpindi Pakistan through a multistage cluster random sampling technique. Subjective well-being was measured by Concise Measure of Subjective Well-being; filial behaviour was examined through receipt of 12 domains; emotional regulation was assessed by using the Emotional Regulation Questionnaire. The structural equation modelling was employed to test the mediation effects.
RESULTS: Cognitive reappraisal was found to partially mediate the relationship between filial behaviour of respect and subjective well-being (β in direct model = 0.661, P
Fulltext Effects of the COVID-19 Pandemic on Psychological Status and Quality of Life among Participants of the Malaysian Elders Longitudinal Research (MELoR) Study

Aravindhan K, Morgan K, Mat S, Hamid TA, Ibrahim R, Saedon NI, et al.

Ann Geriatr Med Res, 2022 Dec;26(4):354-362.
PMID: 36503184 DOI: 10.4235/agmr.22.0134

BACKGROUND: This study aimed to identify differences in quality of life before and during the coronavirus disease 2019 (COVID-19) pandemic and determine the influence of psychological status on the observed changes in the quality of life among older adults.
METHODS: The Malaysian Elders Longitudinal Research study recruited Malaysians aged at least 55 years from 2013 to 2015. Follow-ups were conducted between September and December 2020. Quality of life was determined using the 12-item Control, Autonomy, Self-Realization, and Pleasure questionnaire. Psychological statuses were assessed using the 21-item Depression Anxiety and Stress Scale, 15-item Geriatric Depression Scale, and 4-item Perceived Stress Scale.
RESULTS: This study included data from 706 individuals (mean age, 73.3±6.8 years). We observed reduced quality of life and increased anxiety among 402 (43.1%) and 144 (20.9%) participants, respectively. Participants felt "out of control," "left out," "short of money," and "life was full of opportunities" less often and could "please themselves with what they did" more often. Multivariate analyses revealed increased depression, anxiety, and stress as independent risk factors for reduced quality of life.
CONCLUSION: Individuals with increased depression, anxiety, and stress levels during the pandemic experienced a worsening quality of life. Thus, the development of effective strategies to address the mental health of older adults is needed to mitigate the effects of the pandemic on their quality of life.
Fulltext Effects of acute gamma irradiation on physiological traits and flavonoid accumulation of Centella asiatica

Moghaddam SS, Jaafar H, Ibrahim R, Rahmat A, Aziz MA, Philip E

Molecules, 2011 Jun 17;16(6):4994-5007.
PMID: 21694666 DOI: 10.3390/molecules16064994

In the present study, two accessions of Centella asiatica (CA03 and CA23) were subjected to gamma radiation to examine the response of these accessions in terms of survival rate, flavonoid contents, leaf gas exchange and leaf mass. Radiation Sensitivity Tests revealed that based on the survival rate, the LD(50) (gamma doses that killed 50% of the plantlets) of the plantlets were achieved at 60 Gy for CA03 and 40 Gy for CA23. The nodal segments were irradiated with gamma rays at does of 30 and 40 Gy for Centella asiatica accession 'CA03' and 20 and 30 Gy for accession 'CA23. The nodal segment response to the radiation was evaluated by recording the flavonoid content, leaf gas exchange and leaf biomass. The experiment was designed as RCBD with five replications. Results demonstrated that the irradiated plantlets exhibited greater total flavonoid contents (in eight weeks) significantly than the control where the control also exhibited the highest total flavonoid contents in the sixth week of growth; 2.64 ± 0.02 mg/g DW in CA03 and 8.94 ± 0.04 mg/g DW in CA23. The total flavonoid content was found to be highest after eight weeks of growth, and this, accordingly, stands as the best time for leaf harvest. Biochemical differentiation based on total flavonoid content revealed that irradiated plantlets in CA23 at 20 and 30 Gy after eight weeks contained the highest total flavonoid concentrations (16.827 ± 0.02; 16.837 ± 0.008 mg/g DW, respectively) whereas in CA03 exposed to 30 and 40 Gy was found to have the lowest total flavonid content (5.83 ± 0.11; 5.75 ± 0.03 mg/g DW). Based on the results gathered in this study, significant differences were found between irradiated accessions and control ones in relation to the leaf gas. The highest PN and gs were detected in CA23 as control followed by CA23 irradiated to 20Gy (CA23G20) and CA23G30 and the lowest PN and gs were observed in CA03 irradiated to 40Gy (CA03G40). Moreover, there were no significant differences in terms of PN and gs among the irradiated plants in each accession. The WUE of both irradiated accessions of Centella asiatica were reduced as compared with the control plants (p < 0.01) while Ci and E were enhanced. There were no significant differences in the gas exchange parameters among radiated plants in each accession. Moreover, malondialdehyde (MDA) of accessions after gamma treatments were significantly higher than the control, however, flavonoids which were higher concentration in irradiated plants can scavenge surplus free radicals. Therefore, the findings of this study have proven an efficient method of in vitro mutagenesis through gamma radiation based on the pharmaceutical demand to create economically superior mutants of C. asiatica. In other words, the results of this study suggest that gamma irradiation on C. asiatica can produce mutants of agricultural and economical importance.

PMID: 33968872 DOI: 10.3389/fpubh.2021.594953

Prospective Memory (PM) is a cognitive function affected by aging. PM is the memory of future intentions and is significantly involved in everyday life, especially among older adults. Nevertheless, there are a few studies focused on PM training among healthy older adults and these studies did not report the optimal duration of training regarding improving PM performance among older adults. The present study aimed to determine the effective duration for training PM performance among healthy older adults. The current study was a randomized, controlled, single-blind, within-participants crossover trial including a training program with a duration of 12 h. The sample of 25 older adults aged 55 to 74 years recruited from the active members of the University of the Third Age (U3A), Kuala Lumpur/Selangor, their family members, and friends. The study design ensured some participants would receive the training after baseline while others would wait for 6 weeks after the baseline before receiving the training. All participants were evaluated five times: at baseline, 6, 12, 16, and at 24 weeks post-baseline. Moreover, the training program ensured all participants were assessed after each training session. The minimum number of hours to achieve training effects for this multi-component training program was eight. Results supported the efficacy of the training program in improving PM performance among healthy older adults. Also, the optimal duration for the multicomponent training program on PM performance among healthy older adults was obtained. This trial is registered at isrctn.com (#ISRCTN57600070).
Effect of tocotrienol on the activities of cytosolic glutathione-dependent enzymes in rats treated with 2-acetylaminofluorene

Shamaan NA, Wan Ngah WZ, Ibrahim R, Jarien Z, Top AG, Abdul Kadir K

Biochem Pharmacol, 1993 Apr 06;45(7):1517-9.
PMID: 8471073

The effect of tocotrienol on the activities of glutathione S-transferases (GSTs), glutathione reductase (GR) and glutathione peroxidase (GPx) in rats given 2-acetylaminofluorene (AAF) was investigated over a 20 week period. Liver and kidney GST and liver GR activities were significantly increased after AAF administration. Kidney GPx activities were significantly affected; activity assayed with cumene hydroperoxide (cu-OOH) was increased but activity assayed with H2O2 was reduced. Supplementation of the diet with tocotrienol in the AAF-treated rats reduced the increase in enzyme activities. Tocotrienol on its own had no effect on the enzyme activities.
Fulltext Dyadic effects of attitude toward aging on psychological well-being of older Malaysian couples: an actor-partner interdependence model

Clin Interv Aging, 2013;8:1413-20.
PMID: 24174873 DOI: 10.2147/CIA.S51877

BACKGROUND: There is a growing body of literature indicating that attitudes toward aging significantly affect older adults' psychological well-being. However, there is a paucity of scientific investigations examining the role of older adults' attitudes toward aging on their spouses' psychological well-being. Therefore, the present study aimed to examine the dyadic effects of attitude toward aging on the psychological well-being of older couples.
METHODS: Data for the present study, consisting of 300 couples aged 50 years and older, were drawn from a community-based survey entitled "Poverty among Elderly Women: Case Study of Amanah Ikhtiar" conducted in Peninsular Malaysia. An actor-partner interdependence model using AMOS version 20 (Europress Software, Cheshire, UK) was used to analyze the dyadic data.
RESULTS: The mean ages of the husbands and wives in this sample were 60.37 years (±6.55) and 56.33 years (±5.32), respectively. Interdependence analyses revealed significant association between older adults' attitudes toward aging and the attitudes of their spouses (intraclass correlation =0.59; P<0.001), and similar interdependence was found for psychological well-being (intraclass correlation =0.57; P<0.001). The findings from AMOS revealed that the proposed model fits the data (CMIN/degrees of freedom =3.23; goodness-of-fit index =0.90; confirmatory fit index =0.91; root mean square error of approximation =0.08). Results of the actor-partner independence model indicated that older adults' psychological well-being is significantly predicted by their spouses' attitudes toward aging, both among older men (critical ratio =2.92; P<0.01) and women (critical ratio =2.70; P<0.01). Husbands' and wives' own reports of their attitudes toward aging were significantly correlated with their own and their spouses' psychological well-being.
CONCLUSION: The findings from this study supported the proposed Spousal Attitude-Well-Being Model, where older adults' attitudes toward aging significantly affected their own and their spouses' psychological well-being. The theoretical and practical implications of the findings are discussed.

Living arrangement has been reported to have a significant influence on several mental health statuses of older adults, but their social network may confound this association. This study is aimed at examining the interactive effect of living arrangements and social network on the mental health status among older adults in Malaysia. A total of 2,188 Malaysian older adults living nationwide were included in this cross-sectional study. Participants were classified into four groups according to their living arrangements (living alone or not living alone) and social network size (assessed using Lubben's Social Network Scale-6). Poor social network was defined as the lowest quartile (fourth quartile) of the score. Mental health statuses, which include flourishing in life, life satisfaction, cognitive functions, loneliness, depression, and perceived stress, were measured. Multiple linear regression models, adjusted for age, gender, education, and comorbidities, revealed that a good social network was significantly associated with an increase on the flourishing scale scores, regardless of living arrangements. Not living alone and having good social network was significantly associated with increased Montreal Cognitive Assessment scores and decreased loneliness scores. This study found that living arrangements are not always a risk factor for the mental health status of older adults. However, it may be confounded by the level of their social networks. The results suggested that the effects of social network may exceed the impact of living arrangements. It is recommended that health professionals pay more attention to the social networks of older Malaysians to harness its benefits in improving their mental health status.
Development of a valid measurement instrument to understand self-regulatory driving practices among older drivers in Malaysia

Yeoh SF, Ibrahim R, Oxley J, Hamid TA, Rashid SN

Accid Anal Prev, 2016 Jul;92:1-8.
PMID: 27022713 DOI: 10.1016/j.aap.2016.03.009

Self-regulatory driving is a term used to describe a strategy used by older drivers to preserve mobility and safety, through the adjustment of driving behaviors to match declining physical functions. It can be regarded as a way to prolong driving, or as a process leading to the cessation of driving. Previous studies have striven to explore and understand how older drivers self-regulate their driving. This paper aims to provide an overview of the relevant theories, to explicate the factors that contribute to the adoption of self-regulated driving and the scales used to measure self-regulatory behaviors. This paper also reports on the development and psychometric testing of a Self-Regulatory Driving Practices (SRDP) scale in the Malaysian context. Based on the reviewed theories, adoption of self-regulatory driving practices is a process and involves cognitive thinking that reflects a set of actions. Existing instruments to measure self-regulatory driving practices have been developed and used to identify the behavioral components of self-regulation. Based on literature reviews and a thematic analysis from focus group discussions, a SRDP scale was developed, accommodating the Malaysian context. There were 498 surveys completed by older drivers for further psychometric testing purposes. Results revealed that the final 12-item SRDP scale (α=0.81) consists of four subscales that are planning, avoidance, reduction and alternatives. Suggestions for future research are also recommended.
Fulltext Developing and evaluating the effectiveness of mobile phone-based career intervention for career competencies of Malaysian public managers: Protocol for a mixed method study

BACKGROUND: This study presents a protocol for a mixed method study on the development and evaluation of the effectiveness of mobile phone-based intervention for enhancing career competencies of managers in the Malaysian public service. Career competencies, being central to the self-management and development of one's career, are necessary for proactive management of careers; they help to guide the individuals towards subjective career success which subsequently leads to organization success. However, there is a lack of career competencies intervention practices in the Malaysian public service. Therefore, this study aims to develop and evaluate the effectiveness of a user and expert centric mobile phone-based career intervention program of career competencies among Malaysian public managers. In this study, the Social Cognitive Career Theory (SCCT) is adopted as the framework to develop mobile phone-based intervention for career competencies.
METHOD: This is a sequential exploratory mixed method study which involves, in Phase 1, a qualitative approach: reviewing of literature and interviewing experts and public servants who are users of mobile phones so as to obtain their perspectives regarding the components in the career intervention module and mobile phone application features. A quantitative approach is implemented in Phase 2 that evaluates the mobile phone-based career intervention program.

BACKGROUND: The prevalence of self-neglect among the elderly is expected to rise with a rapid increase in the growth of the older population. However, self-neglect in the elderly and the factors related to it are not fully understood due to the limited research in the area, lack of consensus in the definition of the concept, and limited instrumentation. The purpose of this study was to investigate the relationship between selected socio-demographic factors on self-care and self-neglect among older persons living in the community.
MATERIALS AND METHODS: A cross-sectional survey design with cluster sampling was adopted for the study. Data were gathered from 201 older persons aged 60 years and over in the state of Selangor, Malaysia, through face-to-face interviews in their homes with a team of trained enumerators. A new instrument was developed to measure self-neglect.
RESULTS: The internal consistency of the new instrument showed a reliability of 0.90. A significant bivariate relationship was noted between self-care and self-neglect. The socio-demographic factors were also reported between self-care and self-neglect.
CONCLUSIONS: The new instrument of elder self-neglect (ESN) could be used to measure self-neglect in a community dwelling. The need to increase the self-care skills and the capacity of self-care among older adults is crucial in order to reduce self-neglect and enhance their well-being.
