Food Research, 2018;2(2):124-133.
MyJurnal

Modern science has found that most traditional practice of using stingless bee honey has
great potential as an added value in modern medicine and considered to have a higher
medicinal value than other bee species. However, due to the relatively low output of honey
compared to other honey so, focus on this honey is limited. Hence, this systematic review
provides the updated result on the potential value of stingless bee honey as an antioxidant,
anti-inflammatory, cytotoxicity and antimicrobial. The search strategy was developed in
four databases (Scopus, Medline and Ovid, EMBASE and PubMed) with the search terms
"("honey" and "Kelulut", "honey" and "stingless bee", "honey" and "Trigona", "honey"
and "pot honey", and "honey" and "Melipon")". The merged data was assessed using
PRISMA guidelines and after the duplicates were removed, 1271 articles were segregated.
Afterwards, 1232 articles were eliminated because they do not meet the inclusion criteria
and 39 articles were reevaluated again for eligibility. Finally, after the evaluation process,
only 26 of the articles were chosen for this review. The data of 26 articles of stingless bee
honey were deliberated based on antioxidant properties, anti-inflammatory, cytotoxicity
and analysis of antimicrobial activity. Three articles reported on antioxidant properties,
one article on anti-inflammatory analysis, two articles on cytotoxicity analysis, and twenty
articles on analysis of antimicrobial activity. Based on the feasible affirmation from the
literature, stingless bee honey has an antioxidant capacity that able to decrease the ROS.
ROS able to lead a variety of health problems thus stingless bee honey can be a dietary
supplement to overcome this problem.
Metabolic syndrome: The association of obesity and unhealthy lifestyle among Malaysian elderly people

Johari SM, Shahar S

Arch Gerontol Geriatr, 2014;59(2):360-6.
PMID: 24882592 DOI: 10.1016/j.archger.2014.04.003

The aim of this study is to investigate the prevalence of metabolic syndrome (MetS) and its predictors among Malaysian elderly. A total of 343 elderly aged ≥ 60 years residing low cost flats in an urban area in the central of Malaysia were invited to participate in health screening in community centers. Subjects were interviewed to obtain socio demography, health status and behavior data. Anthropometric measurements were also measured. A total of 30 ml fasting blood was taken to determine fasting serum lipid, glucose level and oxidative stress. MetS was classified according to The International Diabetes Federation (IDF) criteria. The prevalence of MetS was 43.4%. More women (48.1%) were affected than men (36.3%) (p<0.05). Being obese or overweight was the strongest predictor for MetS in men and women (p<0.05, both gender). High carbohydrate intake increased risk of MetS in men by 2.8 folds. In women, higher fat free mass index, physical inactivity and good appetite increased risk of MetS by 3.9, 2.1 and 2.3 folds respectively. MetS affected almost half of Malaysian elderly being investigated, especially women, and is associated with obesity and unhealthy lifestyle. It is essential to develop preventive and intervention strategies to curb undesirable consequences associated with MetS.
Fulltext Validation of a Dietary History Questionnaire against a 7-D Weighed Record for Estimating Nutrient Intake among Rural Elderly Malays

Shahar S, Earland J, Abdulrahman S

Malays J Nutr, 2000 Mar;6(1):33-44.
PMID: 22692390 MyJurnal

Energy and nutrient intake estimated using a pre-coded dietary history questionnaire (DHQ) was compared with results obtained from a 7-d weighed intake record (WI) in a group of 37 elderly Malays residing in rural areas of Mersing District, Johor, Malaysia to determine the validity of the DHQ. The DHQ consists of a pre-coded dietary history with a qualitative food frequency questionnaire which was developed to obtain information on food intake and usual dietary habits. The 7-d WI requires subjects to weigh each food immediately before eating and to weigh any leftovers. The medians of intake from the two methods were rather similar and varied by less than 30% for every nutrient, except for vitamin C (114%). For most of the nutrients, analysis of group means using the Wilcoxon matched pairs signed rank sum test showed no significant difference between the estimation of intake from the DHQ and from the WI, with the exceptions of vitamin C and niacin. The DHQ significantly overestimated the intake of vitamin C compared to the WI (p<0.05), whilst, the intake of niacin was significantly underestimated (p<0.05). The consistency of ranking as assessed using the Spearman's rank correlation coefficient (r) was satisfactory since there were positive correlations between all of the investigated nutrients estimated using the DHQ with those assessed using the WI, except for niacin. Furthermore, both the DHQ and the WI classified approximately 38 to 62% of the subjects into the same tertile for all nutrients, except vitamin C. Therefore, the DHQ was modified by adding a checklist of foods rich in vitamin C and niacin. In conclusion, the DHQ was fairly valid for obtaining the usual intake of most nutrients, particularly on a group basis. These findings indicate that in an elderly population with a high prevalence of illiteracy, a specially designed DHQ can provide very similar estimations to that obtained from 7-d WI.
Fulltext Predictive equations for estimation of stature in Malaysian elderly people

Shahar S, Pooy NS

Asia Pac J Clin Nutr, 2003;12(1):80-4.
PMID: 12737015

Height is an important clinical indicator to derive body mass index (BMI), creatinine height index and also to estimate basal energy expenditure, basal metabolic rate and vital capacity through lung function. However, height measurement in the elderly may impose some difficulties and the reliability is doubtful. Equations estimating height from other anthropometric measures have been developed for Caucasians, but only one study has developed an equation (based on arm span only) for an Asian population. Therefore, a cross sectional study was conducted to develop equations using several anthropometric measurements for estimating stature in Malaysian elderly. A total of 100 adults (aged 30 to 49 y) and 100 elderly subjects (aged 60 to 86 y) from three major ethnic groups of Malays (52%), Chinese (38.5%) and Indians (9.5%) participated in this study. Anthropometric measurements included body weight, height, arm span, half arm span, demi span and knee height were carried out by trained nutritionists. Inter and intra observer errors and also % Coefficient Variation (%CV) were calculated for each anthropometric measurement. Equations to estimate stature were developed from the anthropometric measurements of arm span, demi span and knee height of adults using linear regression analysis according to sex. Elderly subjects were shorter and lighter compared to their younger counterparts. The %CV of anthropometric measurements in adults and elderly subjects ranged between 5 to 6%, with standing height having the lowest %CV. When the equations derived from adults were applied to elderly subjects, it was found that percentage difference between actual height and the estimated value ranged from 1.0 to 3.3%. However, the percentage difference between estimated height from the equations developed in this study compared to those derived from the equations of other populations ranged between 0.2 to 8.7%. In conclusion, standing height is an ideal technique for estimating the stature of individuals. However, in cases where its measurement is not possible or reliable, such as in elderly subjects, height can be estimated from proxy indicators of stature. In this study arm span showed the highest correlation with standing height, which is in agreement with other studies. It should be borne in mind that equations derived from taller statured populations (e.g. Caucasians) may be less accurate when applied to shorter statured populations.

Fulltext Food intakes and habits of rural elderly Malays

Shahar S, Earland J, Rahman SA

Asia Pac J Clin Nutr, 2000 Jun;9(2):122-9.
PMID: 24394398

A cross-sectional nutritional survey was carried out on 350 elderly Malays aged 60 and above from 11 randomly selected villages in a rural area on the east coast of Malaysia. The findings indicated that the mean intakes of energy and of all of the nutrients investigated were below the Malaysian Recommended Dietary Allowances, except for protein and vitamin C. With respect to dietary habits, almost all of the subjects reported that they had breakfast (99.3%), lunch (97.9%) and dinner (90.4%) daily or almost daily (5-6 times/week). However, approximately half of the subjects, especially women, had particular beliefs and prohibitions about specific foods. Most of the subjects usually ate their meals at home, particularly dinner, with 99.3% always having dinner in their own home. Thus, although the rural elderly Malays studied had regular meal intakes, the dietary intake was inadequate. There is a need to plan community-based intervention programmes in order to prevent the subsequent consequences of malnutrition that lead to increased morbidity and mortality.
Development of a screening tool for detecting undernutrition and dietary inadequacy among rural elderly in Malaysia: simple indices to identify individuals at high risk

Shahar S, Dixon RA, Earland J

Int J Food Sci Nutr, 1999 Nov;50(6):435-44.
PMID: 10719584

Undernutrition and the consumption of poor diets are prevalent among elderly people in developing countries. Recognising the importance of the early identification of individuals at high nutritional risk, this study aimed to develop a simple tool for screening. A cross-sectional study was conducted on 11 randomly selected villages among the 62 in Mersing District, Malaysia. Undernutrition was assessed using body mass index, plasma albumin and haemoglobin on 285 subjects. Dietary inadequacy (a count of nutrients falling below two-thirds of the Recommended Dietary Allowances) was examined for 337 subjects. Logistic regression analysis was performed to identify significant predictors of undernutrition and dietary inadequacy from social and health factors, and to derive appropriate indices based on these predictions. The multivariate predictors of undernutrition were 'no joint disease', 'smoker', 'no hypertension', 'depended on others for economic resource', 'respiratory disease', 'perceived weight loss' and 'chewing difficulty', with a joint sensitivity of 56% and specificity of 84%. The equivalent predictors of dietary inadequacy were 'unable to take public transport', 'loss of appetite', 'chewing difficulty', 'no regular fruit intake' and 'regularly taking less than three meals per day', with a joint sensitivity of 77% and specificity of 47%. These predictions, with minor modification to simplify operational use, led to the production of a simple screening tool. The tool can be used by public health professionals or community workers or leaders as a simple and rapid instrument to screen individual at high risk of undernutrition and/or dietary inadequacy.
Fulltext A Prospective Study on Malnutrition and Duration of Hospitalisation among Hospitalised Geriatric Patients Admitted to Surgical and Medical Wards of Hospital Universiti Kebangsaan Malaysia

Shahar S, Wong S, Wan C

Malays J Nutr, 2002 Mar;8(1):55-62.
PMID: 22692439 MyJurnal

Elderly people are known to be at a greater risk of malnutrition, particularly those having diseases or illnesses. A prospective study was undertaken on 92 hospitalised geriatric patients (45.6% males), aged 60 to 89 years old, admitted to surgical and medical wards at Hospital Universiti Kebangsaan Malaysia (HUKM). The study aimed to assess malnutrition at admission, day 3 and day 7 of hospitalisation, and its relation with length of stay in the wards. Malnutrition was assessed using anthropometrics and biochemical indicators. Although the majority of subjects had a normal Body Mass Index (BMI), 10.9% had Chronic Energy Deficiency (CED) and 38% were overweight. A total of 10% subjects had muscle wasting as assessed by Mid-upper Arm Circumference (MUAC). Biochemical tests indicated that women subjects were more likely to have hypoalbuminaemia (p <0.05) whilst, men were at risk of anaemia (p < 0.05). Throughout hospitalisation, there was a significant reduction in body weight, biceps skinfold thickness, calf circumference, MUAC, percentage of body fat and body mass index (BMI) in both males and females (p < 0.05 for all parameters). Biochemical tests on a sub sample of subjects indicated that 71.4% had hypoalbuminaemia and 39.6% were anaemic. Subjects diagnosed with cancer, had loss of appetite or had poor nutritional status as assessed by BMI or MUAC on admission were more likely to be hospitalised longer than or equal to 7 days (p < 0.05 for all parameters). Serum albumin levels at admission correlated positively with MUAC values both on admission (r = 0.608, p <0.01) and at clay seven of hospitalisation (r = 0.906, p < 0.05). There is a need to screen elderly patients at high risk of malnutrition at admission in order to reduce the length of stay and increase their health and nutritional status.
Needs assessment for patients food intake monitoring among Indonesian healthcare professionals

Budiningsari D, Shahar S, Abdul Manaf Z, Susetyowati S

Int Nurs Rev, 2018 Sep;65(3):317-326.
PMID: 28833124 DOI: 10.1111/inr.12394

AIM: The aim of this study was to provide a needs assessment related to the current practice of food intake monitoring for hospitalized adult patients among healthcare professionals and obtain feedback for the development of a new dietary assessment tool.
BACKGROUND: Continuous effort has been made to identify patients at high risk of malnutrition, but monitoring and documentation of nutritional intake are relative less emphasized upon.
METHODS: A needs assessment through a cross-sectional study design was carried out at six hospitals in Yogyakarta, Indonesia. A self-administered semi-structured questionnaire was filled out by 111 respondents recruited from three different professions (nurses, dietitians and serving assistants) in the wards.
RESULTS: Seventy per cent of the respondents perceived that the current dietary assessment tool used to record patients' food intake was simple; however, the disadvantage of this tool was its tedious process of computing nutritional values of food consumed. Furthermore, more than half respondents encountered problems in conducting food intake record of patients, primarily due to limited number of human resources, followed by time constraints and perception that such dietary assessment as not part of their job scope.
DISCUSSION: This study has revealed important information in developing a simple, valid and reliable dietary assessment tool for monitoring food intake of hospitalized patients to be applied by interdisciplinary hospital professionals.
CONCLUSIONS: Awareness of the important on monitoring nutrient intake of patients should be emphasized among healthcare professionals. The current dietary assessment tool requires modification due to lengthy time taken to complete the task and poor accuracy in intake estimation.
IMPLICATION FOR NURSING AND HEALTH POLICY: Hospitals should provide protocols and guidelines of cooperation among interdisciplinary professionals, including nurses, which includes a simple dietary assessment tool to assist nutritional management of hospitalized patients.
Fulltext Association between nutrient adequacy and psychosocial factors with overall rate of weight loss after bariatric surgery

Vanoh D, Shahar S, Mahmood NR

Asia Pac J Clin Nutr, 2015;24(4):610-9.
PMID: 26693745 DOI: 10.6133/apjcn.2015.24.4.11

This was a cross-sectional study that investigated the relationship between nutrient intake and psychosocial factors with the overall rate of weight loss after bariatric surgery among patients who had undergone sleeve gastrectomy in University Kebangsaan Malaysia Medical Centre (UKMMC). Forty-three subjects (15 men and 28 women) were recruited for this study. Subjects completed assessment questionnaires including the Binge Eating Scale (BES), Beck Depression Inventory (BECK), Family Support Questionnaires, and the Index of Peer Relation (IPR). Results showed that the median overall rate of weight loss was 4.3±5.5 kg/month, which was lower when compared to the rate of weight loss at three months which was 5.0±5.6 kg/month. Pre-operative weight was the predictor of overall rate of weight loss (p<0.05, R²=0.52). Binge eating disorder (BED) and depression were also closely associated with each other after bariatric surgery (p<0.001, R²=0.46). Subjects with good compliance to dietary advice had lower scores on the binge eating scale. The mean caloric and protein intake was very low, only 562±310 kcal/day and 29.6±16.1 g/day. The intake of vitamin A, B-1, B-2, B-3, B-12, C, folate, and iron met the Malaysian Recommended Nutrient Intake (RNI). However, the RNI for calcium, zinc, selenium, vitamin D, and vitamin E was not met. In conclusion, although bariatric surgery had many health benefits, several factors hindered weight loss after bariatric surgery. Health care professionals should closely monitor patients after bariatric surgery.
Fulltext Nutritional management of enterocutaneous fistula: a retrospective study at a Malaysian university medical center

Badrasawi MM, Shahar S, Sagap I

J Multidiscip Healthc, 2014;7:365-70.
PMID: 25187726 DOI: 10.2147/JMDH.S58752

Enterocutaneous fistula is a challenging clinical condition with serious complications and considerable morbidity and mortality. Early nutritional support has been found to decrease these complications and to improve the clinical outcome. Location of the fistula and physiological status affect the nutrition management plan in terms of feeding route, calories, and protein requirements. This study investigated the nutritional management procedures at the Universiti Kebangsaan Malaysia Medical Center, and attempted to determine factors that affect the clinical outcome. Nutritional management was evaluated retrospectively in 22 patients with enterocutaneous fistula seen over a 5-year period. Medical records were reviewed to obtain data on nutritional status, biochemical indices, and route and tolerance of feeding. Calories and protein requirements are reported and categorized. The results show that surgery was the predominant etiology and low output fistula was the major physiological category; anatomically, the majority were ileocutaneous. The spontaneous healing rate was 14%, the total healing rate was 45%, and the mortality rate was 22%, with 14% due to fistula-associated complications. There was a significant relationship between body mass index/serum albumin levels and fistula healing; these parameters also had a significant relationship with mortality. Glutamine was used in 50% of cases; however, there was no significant relationship with fistula healing or mortality rate. The nutritional status of the patient has an important impact on the clinical outcome. Conservative management that includes nutrition support is very important in order to improve nutritional status before surgical repair of the fistula.

Inform Health Soc Care, 2013 Jan;38(1):15-26.
PMID: 22957981 DOI: 10.3109/17538157.2012.710684

This study aimed to assess the quality and accuracy of nutrition information about cancer prevention available on the Web. The keywords 'nutrition + diet + cancer + prevention' were submitted to the Google search engine. Out of 400 websites evaluated, 100 met the inclusion and exclusion criteria and were selected as the sample for the assessment of quality and accuracy. Overall, 54% of the studied websites had low quality, 48 and 57% had no author's name or information, respectively, 100% were not updated within 1 month during the study period and 86% did not have the Health on the Net seal. When the websites were assessed for readability using the Flesch Reading Ease test, nearly 44% of the websites were categorised as 'quite difficult'. With regard to accuracy, 91% of the websites did not precisely follow the latest WCRF/AICR 2007 recommendation. The quality scores correlated significantly with the accuracy scores (r = 0.250, p
Serum folate concentration, cognitive impairment, and DNA damage among elderly individuals in Malaysia

Lee LK, Shahar S, Rajab N

Nutr Res, 2009 May;29(5):327-34.
PMID: 19555814 DOI: 10.1016/j.nutres.2009.05.006

The notion that dietary factors affect cognitive function and subsequently the risk of dementia has increased over the years from a global viewpoint. Because low folate intake has been described to impair cognitive function, we tested the hypothesis that low serum folate concentration is associated with cognitive impairment and an attenuated increase in DNA damage. We investigated the relationship between serum folate concentration, cognitive impairment, and DNA damage among elderly people attending health clinics in Klang Valley, an urban area in Malaysia. Two hundred thirty-two participants, composed of 115 men (49.6%) and 117 women (50.4%), were involved; none of the patients were diagnosed with neuropsychiatric problems, nor where they terminally ill. Sociodemography and health variables were assessed through face-to-face interview. Cognitive impairment review was conducted through an Elderly Cognitive Assessment Questionnaire. The estimation of dietary intake, serum folate concentration, and DNA damage was individually analyzed using validated Dietary History Questionnaires, immunoassay methods, and an Alkaline Comet Assay study (10 mL of peripheral venous blood), respectively. Results indicated that more men had cognitive impairment (33.0%) and DNA damage (27.0% for percentage DNA in tail, 22.6% tail moment) compared with women (25.6%, 15.4%, and 15.4%, respectively) (P < .05 for all parameters), recording an average folate deficiency value of 13.9% (0.2% higher than women). Multivariate binary logistic regression analysis outlined the association of cognitive impairment with older age (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.35-5.57), smoking habits (OR, 5.12; 95% CI, 2.48-10.57), poor serum folate concentration (OR, 3.46; 95% CI, 1.26-9.52), and DNA damage (percentage DNA in tail) (OR, 13.70; 95% CI, 1.36-138.29). In conclusion, this study highlighted the important role of serum folate concentration for cognitive function and provided a concise picture regarding the elevated levels of oxidative DNA damage in peripheral lymphocytes.
Fulltext Habitual sugar intake and cognitive impairment among multi-ethnic Malaysian older adults

Chong CP, Shahar S, Haron H, Din NC

Clin Interv Aging, 2019;14:1331-1342.
PMID: 31413554 DOI: 10.2147/CIA.S211534

Background: Sugar is widely consumed in Malaysia, and the excessive intake of sugar has been associated with cognitive functions. However, the association between sugar intake and cognitive impairment among Malaysian older adults is yet to be determined. Purpose: The objective of this study was to evaluate the associations between types and sources of sugar intake and cognitive functions and to identify their risk in predicting cognitive impairment (MMSE score <24). Subjects and methods: A total of 1,209 subjects aged ≥60 years were recruited through multi-stage random sampling from selected states in Malaysia. Dietary intake was derived using a 7-day dietary history questionnaire and supplemented with a quantitative food frequency questionnaire for added sugar intake. Results: The prevalence of cognitive impairment as defined by Mini-Mental State Examination (MMSE) less than 24 was 31.9%, while the prevalence of mild cognitive impairment was 13.1%. The median (IQR) for total sugar intake was 44.60 g/day (26.21-68.81) or 8 tsp, and free sugar intake was 33.08 g/day (17.48-57.26) or 6 tsp. The higher intake of total sugars, free sugars, sucrose, lactose, sugar-sweetened beverages, sugar-sweetened cakes, and dessert was found to be significantly associated with a lower MMSE score, after adjusting for covariates. On the other hand, the consumption of cooked dishes and fruits was significantly associated with a better MMSE score. The adjusted OR for risk of cognitive impairment (MMSE score <24) was 3.30 (95% CI 2.15-5.08) for total sugars and 3.58 (95% CI 2.32-5.52) for free sugars, comparing the highest with the lowest intake percentiles. Conclusion: Excessive sugar consumption among older adults showed a notable association with poor cognitive functions, but longitudinal studies and clinical trials are further needed to clarify the direction of causality and to investigate the underlying mechanism.
Fulltext Urinary incontinence among urban and rural community dwelling older women: prevalence, risk factors and quality of life

Murukesu RR, Singh DKA, Shahar S

BMC Public Health, 2019 Jun 13;19(Suppl 4):529.
PMID: 31196015 DOI: 10.1186/s12889-019-6870-6

BACKGROUND: Urinary incontinence (UI) is known to be more prevalent among women and is associated with decline in quality of life. The aim of our study was to investigate the prevalence, risk factors of urinary incontinence and its impact on quality of life among community dwelling older women living in urban and rural populations.
METHODS: This study was conducted based on secondary data analysed from the third phase of the longitudinal study "Neuroprotective Model for Health Longevity among Malaysian Elderly" (LRGS TUA). Stratification of urban and rural study areas were in accordance to that determined by the Department of Statistics. A total of 814 community dwelling older women (53% urban, 47% rural), aged 60 years and above, across four states within Peninsular Malaysia were included in this analysis. Interview-based questionnaires were used to obtain respondents' sociodemographic details and clinical characteristics. The Timed Up and Go test and Handgrip Strength tests were used to assess physical function. Urinary incontinence was self-reported, and quality of life of those with incontinence was assessed using the King's Health Questionnaire (KHQ).
RESULTS: Prevalence of urinary incontinence was 16% and 23% among older women living in urban and rural areas, respectively. Ethnicity was significantly associated with incontinence among older women in both urban and rural population (p
Fulltext A simple dietary assessment tool to monitor food intake of hospitalized adult patients

PMID: 27555779 DOI: 10.2147/JMDH.S105000

Monitoring food intake of patients during hospitalization using simple methods and minimal training is an ongoing problem in hospitals. Therefore, there is a need to develop and validate a simple, easy to use, and quick tool that enables staff to estimate dietary intake. Thus, this study aimed to develop and validate the Pictorial Dietary Assessment Tool (PDAT).
Nutritional status of rural elderly Malays: dietary and biochemical findings

Shahar S, Earland J, Powers HJ, Rahman SA

Int J Vitam Nutr Res, 1999 Jul;69(4):277-84.
PMID: 10450534 DOI: 10.1024/0300-9831.69.4.277

A cross-sectional nutritional survey was carried out on 350 elderly Malays aged 60 and above from 11 randomly selected villages in a rural area on the East Coast of Malaysia. The findings indicated that the mean intakes of energy and all of the nutrients investigated were below the Malaysian Recommended Dietary Allowances, excepts for protein and vitamin C. Nutrients most likely to be inadequate were vitamin A, thiamine, riboflavin, niacin and calcium, with more than 50% of the subjects having estimated intakes of below 2/3 of the recommendations. However, vitamin A status was adequate, with only 2 subjects being biochemically deficient (plasma retinol < or = 0.7 mmol/l). Approximately a third of the subjects had hypoalbuminaemia (plasma albumin < 3.3 g/dl) and anaemia (Haemoglobin < 12 g/dl for men; < 13 g/dl for women). Riboflavin deficiency, as assessed by an erythrocyte glutathione reductase activation coefficient (EGRAC) of more than 1.35 was identified in 77% of the subjects. The prevalence of vitamin E deficiency (plasma a-tocopherol < or = 12 mmol/l) was 27%, with men being at a greater risk. In conclusion, the dietary intakes of these rural elderly Malays was inadequate. Over three quarters of the sample were biochemically deficient in riboflavin, the functional consequences of which need to be further investigated.
Fulltext Ertapenem-induced neurotoxicity in an end-stage renal disease patient on intermittent haemodialysis: a case report

Shahar S, Arimuthu DA, Mazlan SA

BMC Nephrol, 2022 Nov 08;23(1):360.
PMID: 36348388 DOI: 10.1186/s12882-022-02980-8

BACKGROUND: Carbapenem-induced neurotoxicity is an unusual side effect, with seizure being the most commonly reported symptom. Among the carbapenems, imipenem-cilastin is classically associated with the most severe neurotoxicity side effects. Carbapenem is mainly excreted by the kidney and its half-life is significantly increased in patients with chronic kidney disease (CKD). Therefore, dose adjustment is necessary in such patients. Ertapenem-associated neurotoxicity is increasingly being reported in CKD patients, but rarely seen in patients with recommended dose adjustment.
CASE PRESENTATION: We report a case of a 56-year-old male patient with chronic kidney disease 5 on dialysis(CKD 5D). The patient presented with a history of fever, chills and rigours during a session of haemodialysis (HD). He was diagnosed with Enterobacter cloacae catheter-related blood stream infection and was started on ertapenem. After 13 days of ertapenem, he experienced an acute confusional state and progressed to having auditory and visual hallucinations. His blood investigations and imaging results revealed no other alternative diagnosis. Hence a diagnosis of ertapenem-induced neurotoxicity was made. He had complete resolution of symptoms after 10 days' discontinuation of ertapenem.
CONCLUSION: Our case draws attention to the risk of potentially serious toxicity of the central nervous system in HD patients who receive the current recommended dose of ertapenem. It also highlights that renal dosing in CKD 5D patients' needs to be clinically studied to ensure antibiotic safety.
Fulltext 'Timed Up and Go' test: Age, gender and cognitive impairment stratified normative values of older adults

Ibrahim A, Singh DKA, Shahar S

PLoS One, 2017;12(10):e0185641.
PMID: 28972994 DOI: 10.1371/journal.pone.0185641

AIMS: The aim of this study was to establish 'Timed up and Go' test (TUG) normative data among community dwelling older adults stratified based on cognitive status, gender and age groups.
METHODS: A total of 2084 community dwelling older adults from wave I and II were recruited through a multistage random sampling method. TUG was performed using the standard protocol and scores were then stratified based on with and without mild cognitive impairment (MCI), gender and in a 5-year age groups ranging from ages of 60's to 80's.
RESULTS: 529(16%) participants were identified to have MCI. Past history of falls and medical history of hypertension, heart disease, joint pain, hearing and vision problem, and urinary incontinence were found to have influenced TUG performance. Cognitive status as a mediator, predicted TUG performance even when both gender and age were controlled for (B 0.24, 95% CI (0.02-0.47), β 0.03, t 2.10, p = 0.36). Further descriptive analysis showed, participants with MCI, women and older in age took a longer time to complete TUG, as compared to men with MCI across all age groups with exceptions for some age groups.
CONCLUSION: These results suggested that MCI needs to be taken into consideration when testing older adults using TUG, besides age and gender factors. Data using fast speed TUG may be required among older adults with and without MCI for further understanding.
