Mild cognitive impairment (MCI) is a common condition in the elderly. It is characterized by deterioration of memory, attention, and cognitive function that is beyond what is expected based on age and educational level. MCI does not interfere significantly with individuals' daily activities. It can act as a transitional level of evolving dementia with a range of conversion of 10%-15% per year. Thus, it is crucial to protect older people against MCI and developing dementia. The preventive interventions and appropriate treatments should improve cognitive performance, and retard or prevent progressive deficits. The avoidance of toxins, reduction of stress, prevention of somatic diseases, implementation of mental and physical exercises, as well as the use of dietary compounds like antioxidants and supplements can be protective against MCI. The modification of risk factors such as stopping smoking, as well as the treatment of deficiency in vitamins and hormones by correcting behaviors and lifestyle, can prevent cognitive decline in the elderly. The progressive increase in the growth rate of the elderly population can enhance the rate of MCI all over the world. There is no exact cure for MCI and dementia; therefore, further studies are needed in the future to determine causes of MCI and risk factors of progression from MCI to dementia. This will help to find better ways for prevention and treatment of cognitive impairment worldwide.

A dielectric spectroscopy method was applied to determine major fatty acids composition in vegetable oils. Dielectric constants of vegetable oils were measured in the frequency range of 5–30 MHz. After data pre-treatment, prediction models were constructed using partial least squares (PLS) regression between dielectric spectral values and the fatty acids compositions measured by gas chromatography. Generally, the root means square error of validation (RMSECV) was less than 11.23% in the prediction of individual fatty acids. The determination coefficient (R 2 ) between predicted and measured oleic, linoleic, mono-unsaturated, and poly-unsaturated fatty acids were 0.84, 0.77, 0.84, and 0.84, respectively. These results indicated that dielectric spectroscopy coupled with PLS regression could be a promising method for predicting major fatty acid composition in vegetable oils and has the potential to be used for in-situ monitoring systems of daily consumption of dietary fatty acids.

Effects of tai chi on postural balance and quality of life among the elderly with gait disorders: A systematic review
2023
Tai Chi is good for improving the physical fitness of older adults. But few studies have reported the effects of Tai Chi on the postural balance and quality of life of older adults with gait disorders. This review aimed to assess the influence of tai chi on postural stability and quality of life in older adults with abnormal gait. According to the literature retrieval principles, the works published from the inception date to May 2023 were retrieved, including the following databases: PubMed, Scopus, Web of Science, China National Knowledge Infrastructure, EBSCOhost, and Google Scholar. Subsequently, literature screening and quality assessment were performed. A total of 16 randomized controlled trials were included in this study, Tai Chi intervention can affect populations with Parkinson's disease (PD), no exercise, mild cognitive impairment (MCI), chronic stroke, sedentary, fear of falling, or history of falling. Postural instability is associated with balance, gait, the Unified Parkinson's Disease Rating Scale Motor Subscale 3 (UPDRS III), mobility, lower body strength, and falls. Only two articles looked at quality of life. The Yang style is the most commonly used in the intervention. Nonetheless, most studies were performed on female participants, hence, more research on older male populations is needed. Tai Chi intervention benefits postural balance in patients with gait disorders. 12 weeks is the most common intervention period for patients with gait disorders. The frequency of intervention is seven articles twice a week, and the intervention time is about 60 minutes. The Tai Chi intervention methods in this study involve Yang Style, Sun Style, Taoist Tai Chi, and Health Qigong Tai Chi, but the Yang Style Tai Chi intervention is the most widely used.

Although hemodialysis treatment has greatly increased the life expectancy of end stage renal disease patients, low quality of life among hemodialysis patients is frequently reported. This cross-sectional study aimed to determine the relationship between medical history, hemodialysis treatment and nutritional status with the mental and physical components of quality of life in hemodialysis patients. Respondents (n=90) were recruited from Hospital Kuala Lumpur and dialysis centres of the National Kidney Foundation of Malaysia. Data obtained included socio-demography, medical history, hemodialysis treatment and nutritional status. Mental and physical quality of life were measured using the Mental Composite Summary (MCS) and Physical Composite Summary (PCS) of the Short-Form Health Survey 36-items, a generic core of the Kidney Disease Quality of Life Short Form. Two summary measures and total SF-36 was scored as 0-100, with a higher score indicating better quality of life. Approximately 26 (30%) of respondents achieved the body mass index (24 kg/m(2)) and more than 80% (n=77) achieved serum albumin level (>35.0 mg/dL) recommended for hemodialysis patients. The majority of respondents did not meet the energy (n=72, 80%) and protein (n=68,75%) recommendations. The total score of SF-36 was 54.1 ± 19.2, while the score for the mental and physical components were 45.0 ± 8.6 and 39.6 ± 8.6, respectively. Factors associated with a higher MCS score were absence of diabetes mellitus (p=0.000) and lower serum calcium (p=0.004), while higher blood flow (p=0.000), higher serum creatinine (p=0.000) and lower protein intake (p=0.006) were associated with a higher PCS score. To improve the overall quality of life of hemodialysis patients, a multidisciplinary intervention that includes medical, dietetic and psychosocial strategies that address factors associated with mental and physical quality of life are warranted to reduce further health complications and to improve quality of life.

Background Sarcopenia is an age‐related muscle disease often accompanied by comorbidities, mobility issues and cognitive decline, which can limit treatment adherence in older adults. Owing to the reversible nature of sarcopenia, there has been a growing number of randomized controlled trials conducted in recent years. Yet, many randomized controlled trials (RCTs) are conducted under ideal conditions (explanatory trials), limiting their real‐world applicability. In contrast, pragmatic trials aim to better reflect the complexities of clinical practice. Objective This study is aimed at assessing the level of pragmatism in current sarcopenia RCTs and identifying design gaps to further improve the clinical relevance and feasibility of future trials in the real world. Methods A systematic review was conducted on MEDLINE (via Ovid), Embase and Cochrane Central Register of Controlled Trials (PRISMA guidelines; PROSPERO: CRD42024571027). Eligible studies included RCTs on sarcopenia treatment using a consensus definition and published until March 2024. The PRECIS‐2 tool was used to assess the level of pragmatism of these RCTs across nine standard domains (eligibility, recruitment, setting, organization, flexibility of delivery, flexibility of adherence, follow‐up, primary outcome and primary analysis), with an additional ‘control’ domain. The total PRECIS‐2 score was calculated, and subgroup analyses were conducted by intervention type, geographical location, sample size, study duration and sarcopenia definition. A higher PRECIS‐2 score indicates greater trial pragmatism. The risk of bias was assessed using the Cochrane Risk of Bias 2.0 tool. Results Of the 3985 references reviewed, 54 RCTs met the inclusion criteria. The mean PRECIS‐2 score across its 10 domains was 2.93 (SD 1.30), reflecting a balance of explanatory and pragmatic characteristics. Organization, recruitment and primary outcome were identified as the most pragmatic domains, whereas eligibility, adherence and follow‐up were the most explanatory. Subgroup analyses revealed that geographical location and sarcopenia definitions impacted significantly the overall PRECIS‐2 score. More precisely, studies conducted in Asia achieved higher pragmatism scores, with significant differences in setting (p = 0.029), follow‐up (p = 0.014) and control (p = 0.042) domains. Studies using Asian sarcopenia criteria (e.g., AWGS) were also more pragmatic, particularly in the eligibility (p = 0.031) and control (p = 0.005) domains. Conclusion This systematic review reveals a persistent gap between explanatory and pragmatic designs in sarcopenia trials. Despite growing research, few studies reflect real‐world conditions. Key domains like eligibility, adherence and follow‐up remain overly controlled. Greater pragmatism is needed to ensure future trials yield evidence that is both robust and clinically applicable.

Background
Infants and young children 6–24 months of age are the most nutritionally vulnerable groups, as their needs for vitamins and minerals are high relative to the amount of food they consume. This study determines the effect of Micronutrient Powder Supplementation (MNP) on growth and hemoglobin of infants in Gaza Strip, Palestine.
Method
This was a two-arm parallel-group randomized controlled trial conducted in two health care clinics of the United Nations Relief and Work Agency (UNRWA) at the Middle Area governorate of Gaza Strip, Palestine. A total of 200 healthy infants aged 6-month-old were recruited and randomized to receive 3 sachets/week of MNP for 12 months alongside with the National Micronutrient Supplement (NMS) (
n
= 100) or NMS alone (
n
= 100). Weight, length, blood hemoglobin, and dietary intakes were measured at 6, 9, 12, 15, 18, and 21 (3 months after the end of intervention) months of age. Analysis was by intention to treat.
Results
The experimental group had a higher concentration of hemoglobin at 12 and 15 months than did the control group, and a significant difference (
p
< 0.05) was observed at 15 months only. Significantly greater weight, length, weight-for-age, length-for-age, and weight-for-length z-scores were observed in the experimental group than that in the control group at 12 and 15 months (
p
< 0.05). The prevalence of anemia (18% vs. 52%) and stunting (1% vs. 11%) were higher in the control than the experimental group, respectively. After controlling for sex, similar findings were reported.
Conclusions
Addition of MNP to the existing NMS program improved the nutritional status of young children. The potential benefits of MNP supplementation on physical growth and hemoglobin should be considered in the existing NMS program.

Background: This study aimed to investigate factors associated with bone resorption status and determine the independent and interactive effects of dietary acid load (DAL) and cardiometabolic syndrome (CMS) on bone resorption in post-menopausal women. Methods: Overall, 211 community-dwelling post-menopausal women were recruited from the National Council of Senior Citizens Organization, Malaysia. DAL was estimated using the potential renal acid load from the food frequency questionnaire. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and smoking behaviour was assessed using the Global Adult Tobacco Survey 2011. Serum 25(OH) vitamin D levels were determined using the ADVIA Centaur vitamin D assay and serum C-terminal telopeptides of type I collagen (CTX1) were used as surrogate markers to assess bone resorption. CMS was determined based on the harmonised criteria. Results: Age (β = –0.145, t = –2.002, P < 0.05) was negatively associated while DAL (β = 0.142, t = 2.096, P < 0.05) and sleep quality (β = 0.147, t = 2.162, P < 0.05) were positively associated with CTX1. Height was positively correlated with CTX1 (r = 0.136, P < 0.05). Conversely, other variables (CMS traits, CMS, serum 25(OH) vitamin D level, years of menopause, years of education and physical activity) were not significantly associated with CTX1 levels. There was no significant interaction between DAL and CMS on bone resorption. Conclusion: Our findings propose that high DAL, but not CMS, is a potential risk factor for bone resorption. The analysis did not demonstrate the combined effects of DAL and CMS on bone resorption.

The impact of Movement Control Order during the COVID-19 pandemic on lifestyle behaviours and body weight changes: Findings from the MyNutriLifeCOVID-19 online survey
2022
The COVID-19 pandemic lockdowns have affected daily lives of the communities worldwide. This study aims to determine the lifestyle behaviours and their associations with body weight changes among Malaysian adults during the Movement Control Order (MCO) due to COVID-19 pandemic.
A total of 1319 Malaysian adults participated in this cross-sectional online survey. Information on anthropometric data including body weight and height, and lifestyle behaviours including eating pattern, physical activity, and sleep pattern were self-reported by the respondents. A multivariable generalised linear mixed model was used to assess the associations between lifestyle behaviours and body weight changes with adjustment of confounding factors; namely, age, sex, ethnicity, and body weight status before MCO.
During MCO, 41.2% of the respondents perceived that their eating patterns were healthier, but 36.3% reduced their physical activities, and 25.7% had a poorer sleep quality. Further, the proportion of adults who reported having lose weight (32.2%) was almost similar to those who reported having gained weight (30.7%). Lifestyle behaviours including less frequent practice of healthy cooking methods and lunch skipping were associated with weight gain, while less frequent consumption of high fat foods, more frequent physical activity, and good sleep latency were associated with lower risk of weight gain. In contrast, practicing healthy eating concept, skipped lunch, and more frequent physical activity were significantly associated with weight loss.
Lifestyle behaviours were associated with body weight changes during MCO. While the COVID-19 pandemic lockdown is necessary to prevent further spread of the disease, promoting healthy lifestyle practices during lockdown should be implemented for a healthy weight and better health.

Addressing nutritional requirements of ageing consumers in Asia - recommendations from an expert workshop
2019
The number of older persons in Asia is expected to triple by 2050. Ageing is associated with non-communicable chronic diseases, malnutrition, and geriatric syndromes, which influences the burden on the cost related to healthcare, health outcomes, and the quality of life. Experts in the field of older adult nutrition from Asia, Australia, and Europe were invited to participate in a two-day workshop to review the available data, current policies and programs for the ageing population in different countries of Asia to identify the gaps in knowledge and to develop recommendations for action. In Asia, most of the data pertaining to health status, nutritional status, and nutrient intake of the older persons were mainly obtained by conducting studies in nursing homes or hospitals and small cohort studies. There were limited country-specific data on this population. Moreover, the available data pertaining to different countries were difficult to compare due to differences in the reporting format and reference values used. Although nutrition initiatives and policies were realized and public education was conducted to support the older persons, most of these efforts targeted the general population rather than the older persons population segment. In healthcare management, a higher amount of education is required pertaining to the knowledge of nutritional requirements and appropriate feeding of the older persons to reduce underfeeding and its consequences. The expert group recommended the use of a systematic approach for reviewing data pertaining to different countries, initiatives, and programs to further evaluate the available data to underpin future research.

Protein-energy wasting (PEW) is a devastating metabolic derangement that leads to increased morbidity and mortality in hemodialysis (HD) patients. This study aimed to determine the diagnostic test accuracy of bioelectrical impedance analysis derived-phase angle (PhA) in detecting PEW among HD patients. This was a multi-centre, cross-sectional study conducted amongst 152 multi-ethnic HD patients in Klang Valley, Malaysia. PEW was assessed using the International Society of Renal Nutrition and Metabolism criteria as the reference method. PhA was measured using a multi-frequency bioelectrical impedance spectroscopy at 50 kHz. Multiple and logistic regressions were used to determine factors associated with PhA and PEW diagnosis, respectively. A receiver operating characteristics curve analysis was used to establish the gender-specific PhA cut-offs to detect PEW. PEW existed in 21.1% of the HD patients. PhA was found as an independent predictor of PEW (adjOR = 0.308, p = 0.001), with acceptable to excellent discriminative performance (adjAUCmale = 0.809; adjAUCfemale = 0.719). Male patients had higher PhA cut-off compared to female patients (4.26° vs. 3.30°). We concluded that PhA is a valid and pragmatic biomarker to detect PEW in multi-ethnic Malaysian HD patients and a gender-specific cut-off is necessary, attributed to the gender differences in body composition.
