Fulltext Combating obesity through healthy eating behavior: a call for system dynamics optimization

Abidin NZ, Mamat M, Dangerfield B, Zulkepli JH, Baten MA, Wibowo A

PLoS One, 2014;9(12):e114135.
PMID: 25502170 DOI: 10.1371/journal.pone.0114135

Poor eating behavior has been identified as one of the core contributory factors of the childhood obesity epidemic. The consequences of obesity on numerous aspects of life are thoroughly explored in the existing literature. For instance, evidence shows that obesity is linked to incidences of diseases such as heart disease, type-2 diabetes, and some cancers, as well as psychosocial problems. To respond to the increasing trends in the UK, in 2008 the government set a target to reverse the prevalence of obesity (POB) back to 2000 levels by 2020. This paper will outline the application of system dynamics (SD) optimization to simulate the effect of changes in the eating behavior of British children (aged 2 to 15 years) on weight and obesity. This study also will identify how long it will take to achieve the government's target. This paper proposed a simulation model called Intervention Childhood Obesity Dynamics (ICOD) by focusing the interrelations between various strands of knowledge in one complex human weight regulation system. The model offers distinct insights into the dynamics by capturing the complex interdependencies from the causal loop and feedback structure, with the intention to better understand how eating behaviors influence children's weight, body mass index (BMI), and POB measurement. This study proposed a set of equations that are revised from the original (baseline) equations. The new functions are constructed using a RAMP function of linear decrement in portion size and number of meal variables from 2013 until 2020 in order to achieve the 2020 desired target. Findings from the optimization analysis revealed that the 2020 target won't be achieved until 2026 at the earliest, six years late. Thus, the model suggested that a longer period may be needed to significantly reduce obesity in this population.

Association of traumatic head injuries and maxillofacial fractures: A retrospective study

Abosadegh MM, Rahman SA, Saddki N

Dent Traumatol, 2017 Oct;33(5):369-374.
PMID: 28504848 DOI: 10.1111/edt.12349

BACKGROUND/AIMS: The association of traumatic head injury (THI) with maxillofacial fractures (MFF) is a major health concern worldwide. In spite of the close anatomical proximity of maxillofacial bones to the cranium, the association of THI with MFF is controversial. The aim of this study was to assess the association between THI and MFF. Other factors associated with THI in patients with MFF were also investigated.
MATERIALS AND METHODS: A hospital-based retrospective study was conducted at the OMFS Unit, Hospital USM, Kelantan, Malaysia. From 12 June 2013 to 31 December 2015, 473 patient records with MFF were reviewed to evaluate the association of THI and MFF.
RESULTS: A total of 331 patients (69.98%) presented with concomitant THI. The most common associated THI were cranial bone fractures (68.6%) followed by intracranial injuries and concussion. A significant association existed between the Glasgow coma scale (GCS) score and the presence of THI concomitant MFF with P-value

Abu Zaid Z, Shahar S, Jamal AR, Mohd Yusof NA

Asia Pac J Clin Nutr, 2012;21(4):502-10.
PMID: 23017308

A randomised trial was carried out to determine the effect of supplementation of fish oil among 51 children with leukaemia aged 4 to 12 years on appetite level, caloric intake, body weight and lean body mass. They were randomly allocated into the trial group (TG) and the control group (CG). At baseline, 30.8% of TG subjects and 44.0% of CG subjects were malnourished and 7.7% of subject from TG and 28.0% from CG were classified as stunted. The majority of subjects from TG and CG were in the mild malnutrition category for mid upper arm muscle circumference (MUAMC)-for-age. The TG group showed significant increment in MUAMC (0.13 cm vs -0.09 cm) compared with CG at 8 weeks (p<0.001). There was a significant higher increase for appetite level (0.12±0.33) (p<0.05) and an increasing trend on energy and protein intake in the TG group (213±554 kcal; 3.64 ±26.8 g) than in the CG group. In conclusion, supplementation of fish oil has a positive effect on appetite level, caloric intake and MUAMC among children with leukaemia.

Outbreak of fatal childhood viral infection in Sarawak, Malaysia in 1997: inocula of patients' clinical specimens induce apoptosis in vitro

Abubakar S, Shafee N, Chee HY

Malays J Pathol, 1998 Dec;20(2):71-81.
PMID: 10879266

Identification of the aetiologic agent(s) associated with an outbreak of fatal childhood viral infection in Sarawak, Malaysia, in mid 1997 remains elusive. It is reported here that African green monkey kidney (Vero) and human monocytic (U937) cells treated with inocula derived from clinical specimens of some of these fatal cases showed the presence of cellular genomic DNA degradation when the extracted DNA was separated by pulsed field gel electrophoresis (PFGE), oligonucleosomal DNA ladders characteristic of apoptotic cells when the infected cells' DNA was separated by agarose gel electrophoresis, and apoptotic cellular DNA fragmentation when cells were stained using terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL). These results suggest that inocula derived from the patients' clinical specimens contain factors which stimulate apoptotic cellular responses in vitro.

Biotin-thiamine responsive basal ganglia disease: a retrospective review of the clinical, radiological and molecular findings of cases in Kuwait with novel variants

Aburezq M, Alahmad A, Alsafi R, Al-Tawari A, Ramadan D, Shafik M, et al.

Orphanet J Rare Dis, 2023 Sep 05;18(1):271.
PMID: 37670342 DOI: 10.1186/s13023-023-02888-y

BACKGROUND: Biotin-thiamine-responsive basal ganglia disease (BTBGD) is a rare autosomal recessive neurometabolic disorder that is caused by biallelic pathogenic SLC19A3 variants and is characterized by subacute encephalopathy associated with confusion, convulsions, dysphagia, dysarthria, or other neurological manifestations.
METHODS: A retrospective review of the data registry in Kuwait Medical Genetics Center for all cases diagnosed clinically and radiographically and confirmed genetically with BTBGD.
RESULTS: Twenty one cases from 13 different families were diagnosed with BTBGD in Kuwait. Most cases (86%) presented with confusion, dystonia, convulsions, or dysarthria, while three individuals were diagnosed pre-symptomatically during familial targeted genetic screening. Symptoms resolved completely within 2-week of treatment in two-thirds of the symptomatic cases but progressed in six of them to a variety of severe symptoms including severe cogwheel rigidity, dystonia and quadriparesis due to delayed presentation and management. Neuroradiological findings of the symptomatic cases revealed bilateral central changes in the basal ganglia. Two novel homozygous missense SLC19A3 variants were detected in a Kuwaiti and a Jordanian individuals, in addition to the previously reported Saudi founder homozygous variant, c.1264A > G; p.(Thr422Ala) in the remaining cases. Age of diagnosis ranged from newborn to 32 years, with a median age of 2-3 years. All cases are still alive receiving high doses of biotin and thiamine.
CONCLUSION: This is the first study reporting the phenotypic and genotypic spectrum of 21 individuals with BTBGD in Kuwait and describing two novel SLC19A3 variants. BTBGD is a treatable neurometabolic disease that requires early recognition and treatment initiation. This study highlights the importance of performing targeted molecular testing of the founder variant in patients presenting with acute encephalopathy in the region.

Automated characterization of fatty liver disease and cirrhosis using curvelet transform and entropy features extracted from ultrasound images

Acharya UR, Raghavendra U, Fujita H, Hagiwara Y, Koh JE, Jen Hong T, et al.

Comput Biol Med, 2016 12 01;79:250-258.
PMID: 27825038 DOI: 10.1016/j.compbiomed.2016.10.022

Fatty liver disease (FLD) is reversible disease and can be treated, if it is identified at an early stage. However, if diagnosed at the later stage, it can progress to an advanced liver disease such as cirrhosis which may ultimately lead to death. Therefore, it is essential to detect it at an early stage before the disease progresses to an irreversible stage. Several non-invasive computer-aided techniques are proposed to assist in the early detection of FLD and cirrhosis using ultrasound images. In this work, we are proposing an algorithm to discriminate automatically the normal, FLD and cirrhosis ultrasound images using curvelet transform (CT) method. Higher order spectra (HOS) bispectrum, HOS phase, fuzzy, Kapoor, max, Renyi, Shannon, Vajda and Yager entropies are extracted from CT coefficients. These extracted features are subjected to locality sensitive discriminant analysis (LSDA) feature reduction method. Then these LSDA coefficients ranked based on F-value are fed to different classifiers to choose the best performing classifier using minimum number of features. Our proposed technique can characterize normal, FLD and cirrhosis using probabilistic neural network (PNN) classifier with an accuracy of 97.33%, specificity of 100.00% and sensitivity of 96.00% using only six features. In addition, these chosen features are used to develop a liver disease index (LDI) to differentiate the normal, FLD and cirrhosis classes using a single number. This can significantly help the radiologists to discriminate FLD and cirrhosis in their routine liver screening.

Fulltext Word learning from a tablet app: Toddlers perform better in a passive context

Ackermann L, Lo CH, Mani N, Mayor J

PLoS One, 2020;15(12):e0240519.
PMID: 33259476 DOI: 10.1371/journal.pone.0240519

In recent years, the popularity of tablets has skyrocketed and there has been an explosive growth in apps designed for children. Howhever, many of these apps are released without tests for their effectiveness. This is worrying given that the factors influencing children's learning from touchscreen devices need to be examined in detail. In particular, it has been suggested that children learn less from passive video viewing relative to equivalent live interaction, which would have implications for learning from such digital tools. However, this so-called video deficit may be reduced by allowing children greater influence over their learning environment. Across two touchscreen-based experiments, we examined whether 2- to 4-year-olds benefit from actively choosing what to learn more about in a digital word learning task. We designed a tablet study in which "active" participants were allowed to choose which objects they were taught the label of, while yoked "passive" participants were presented with the objects chosen by their active peers. We then examined recognition of the learned associations across different tasks. In Experiment 1, children in the passive condition outperformed those in the active condition (n = 130). While Experiment 2 replicated these findings in a new group of Malay-speaking children (n = 32), there were no differences in children's learning or recognition of the novel word-object associations using a more implicit looking time measure. These results suggest that there may be performance costs associated with active tasks designed as in the current study, and at the very least, there may not always be systematic benefits associated with active learning in touchscreen-based word learning tasks. The current studies add to the evidence that educational apps need to be evaluated before release: While children might benefit from interactive apps under certain conditions, task design and requirements need to consider factors that may detract from successful performance.

Adam BA

Med J Malaysia, 1980 Jun;34(4):370-4.
PMID: 7219266

Two hundred and three patients with psoriasis, who attended the skin clinic were studied to identify the pattern of sporiasis. The incidence was 4%. It was more common in Indians than in the other ethnic groups and this was found to be statistically significant. Males were affected twice as common, 12.5% gave a positive family history, the lower limbs and the scalp were the commonest site, and pruritus was frequent. The pattern appears similar to those in the west.

Fulltext Coarctation of aorta repair at the National Heart Institute (1983-1994)

Adeeb SMSJ, Leman H, Sallehuddin A, Yakub A, Awang Y, Alwi M

Med J Malaysia, 2004 Mar;59(1):11-4.
PMID: 15535329

This retrospective study illustrates our approach to this problem over the years, from performing subclavian flap aortoplasty initially to the more accepted procedure now, which is resection and end-to-end anastomosis. Coarctation of aorta in our population is seen in a varying age groups and are also associated with other cardiac anomalies including both acyanotic and cyanotic congenital cardiac defects. Therefore a wide variety of surgical procedures were performed including resection of the coarcted segment and end-to-end anastomosis, subclavian flap aortoplasty, patch aortoplasty and synthetic tube graft interposition. Subclavian flap aortoplasty is not widely practised anymore in favour of resection with end-to-end anastomosis. Fifty four point four percent of patients had isolated coarctation, 10.5% had associated valvular defects, 28.1% had other simple congenital defects and 7.0% had associated complex cyanotic congenital defects. Perioperative mortality was 5.26% and is correlated with the younger age of patients at time of surgery and severity of cardiac failure at time of presentation. We did not see any difference in mortality for patients with complex congenital disease or between the different surgical procedures. However, we did find that in the early period when resection with end-to-end anastomosis was performed, there was a significantly higher incidence of morbidities.

Evaluation of nutritional quality of complementary foods formulated from blends of Nigerian yellow maize (Zea mays), soybean (Glycine max) and crayfish (Procambarus clarkii)

Adegbusi HS, Ismail A, Mohd Esa N, Mat Daud ZA

J Sci Food Agric, 2022 Dec;102(15):6961-6973.
PMID: 35672266 DOI: 10.1002/jsfa.12057

BACKGROUND: Plant-based complementary foods (CFs) supply insufficient amount of nutrients to meet recommended nutrient intakes for 6-23-month-old children. The present study determined the nutritional quality of CFs formulated from blends of Nigerian yellow maize (Zea mays), soybean (Glycine max) and crayfish (Procambarus clarkii). Three CFs were formulated; namely, maize flour (MF, 100:0% w/w), blends of maize and soybean flour (MSF, 72:28% w/w), and maize, soybean and crayfish flour (MSCF, 80:10:10% w/w). Nutritional quality was evaluated using analyses of chemical composition of CFs and of protein quality of complementary food diets. Data were compared by multivariate analysis of variance and significantly differentiated. Nine selected nutritional criteria were used to decide the CF that had best nutritional characteristics compared to MF and fortified wheat flour (FWMF).
RESULTS: Total scores obtained from the selected nutritional criteria ranked MSCF, with total score of 15, as the lowest and thus it was considered to have the most desirable nutritional characteristics compared to MF, MSF and FWMF, which had respective total scores of 31, 22 and 20.
CONCLUSION: Conclusively, MSCF may serve as a better alternative CF for MF, MSC and FWMF. The present study has produced a potential alternative cost-effective and adequate CF, formulated from crayfish (P. clarkii) supplementation of locally available blend of yellow maize (Z. mays) and soybean (G. max), for the poor human population, aiming to encourage the consumption of animal-sourced CF for alleviating the prevalence of childhood undernutrition. © 2022 Society of Chemical Industry.

Adlina AR, Chong YJ, Shatriah I

Singapore Med J, 2014 May;55(5):253-6.
PMID: 24862748

INTRODUCTION: Available data on traumatic cataract in Asian children is primarily confined to South Asian countries. We aimed to describe the demographics, nature of injury and visual outcomes of Malaysian children with traumatic cataract from a suburban area, and discuss the literature on Asian children with this condition.

METHODS: We conducted a retrospective study of 29 children below 17 years of age who were diagnosed with traumatic paediatric cataract and who attended Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2000 and December 2010. Follow-up periods ranged from 12 to 120 months. Demographic data, clinical features, mechanism and extent of injury, and final visual outcome were recorded.

RESULTS: The study population was predominantly male. The right eye was injured in 62.07% of patients. A majority of patients had penetrating injuries, with the most common cause being injury by an organic foreign body (24.14%). Presenting visual acuity worse than 6/60 was observed in 68.97% of patients. Only 34.48% of patients had a final corrected visual acuity of 6/12 and better. 55.18% of patients were operated on within less than one month of their injuries. A majority of children sustained concurrent injuries to the anterior segment structures. Corneal opacity and amblyopia were the most common causes of poor final visual acuity.

CONCLUSION: Health education and awareness are essential tools that can prevent avoidable blindness due to traumatic cataract in the paediatric population. The importance of rehabilitation programmes for these patients should be emphasised.

PMID: 24508408 DOI: 10.1016/j.braindev.2013.12.009

Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) are established subgroups of mitochondrial encephalomyopathy. m.3243A>G a common point mutation is detected in tRNA in majority of patients with MELAS phenotype whereas m.8344A>G point mutation in tRNA is observed, in MERRF phenotype. Adrenal insufficiency has not been reported in mitochondrial disease, except in Kearns-Sayre Syndrome (KSS), which is a mitochondrial deletion syndrome. We report an unusual presentation in a five year old boy who presented with clinical phenotype of MELAS and was found to have m.8344A>G mutation in tRNA. Addison disease was identified due to hyperpigmentation of lips and gums present from early childhood. This is the first report describing adrenal insufficiency in a child with MELAS phenotype.

: Glanzmann's thrombasthenia is a rare inherited bleeding disorder characterized by the quantitative or qualitative defect of glycoprotein IIb/IIIa receptor on platelets which leads to ineffective aggregation. Light transmittance aggregometry is considered as the gold standard for diagnosis of Glanzmann's thrombasthenia. Thromboelastography (TEG) is a global hemostatic assay which measures clot formation, clot strengthening and fibrinolysis. This study evaluates the clinical, laboratory and TEG profiles in patients with Glanzmann's thrombasthenia. Bleeding score by (International Society on Thrombosis and Haemostasis) ISTH-bleeding assessment tool (bleeding score), laboratory tests to diagnose Glanzmann's thrombasthenia, and TEG parameters were correlated in 11 Glanzmann's thrombasthenia patients. Seventeen participants with normal bleeding score were included as controls. Bleeding score was increased in all patients. The highest bleeding score was in an adult female (26), whereas the lowest score (4) was in two children of less than 1 year. Majority of TEG parameters (except R-time) showed a statistically significant difference between Glanzmann's thrombasthenia patients and controls (K-time: P

Fulltext Prescription patterns and appropriateness of antibiotics in the management of cough/cold and diarrhea in a rural tertiary care teaching hospital

Ahmad A, Khan MU, Malik S, Mohanta GP, Parimalakrishnan S, Patel I, et al.

J Pharm Bioallied Sci, 2016 Oct-Dec;8(4):335-340.
PMID: 28216959 DOI: 10.4103/0975-7406.199340

BACKGROUND: Acute gastroenteritis and respiratory illnesses are the major causes of morbidity and mortality in children under 5 years of age. The objective of this study was to evaluate the prescription pattern of antibiotic utilization during the treatment of cough/cold and/or diarrhea in pediatric patients.

METHODS: A descriptive, cross-sectional study was conducted for 6 months in pediatric units of a tertiary care hospital in South India. Children under 5 years of age presenting with illness related to diarrhea and/or cough/cold were included in this study. Data were collected by reviewing patient files and then assessed for its appropriateness against the criteria developed in view of the Medication Appropriateness Index and Guidelines of the Indian Academy of Pediatrics. The results were expressed in frequencies and percentages. Chi-square test was used to analyze the data. A P < 0.05 was considered statistically significant.

RESULTS: A total of 303 patients were studied during the study period. The mean age of the patients was 3.5 ± 0.6 years. The majority of children were admitted mainly due to chief complaint of fever (63%) and cough and cold (56.4%). The appropriateness of antibiotic prescriptions was higher in bloody and watery diarrhea (83.3% and 82.6%; P < 0.05). Cephalosporins (46.2%) and penicillins (39.9%) were the most commonly prescribed antibiotics, though the generic prescriptions of these drugs were the lowest (13.5% and 10%, respectively). The seniority of prescriber was significantly associated with the appropriateness of prescriptions (P < 0.05). Antibiotics prescription was higher in cold/cough and diarrhea (93.5%) in comparison to cough/cold (85%) or diarrhea (75%) alone.

CONCLUSIONS: The study observed high rates of antibiotic utilization in Chidambaram during the treatment of cough/cold and/or diarrhea in pediatric patients. The findings highlight the need for combined interventions using education and expert counseling, targeted to the clinical conditions and classes of antibiotic for which inappropriate usage is most common.

Patient Factors in Inappropriate Antibiotic Prescribing for Upper Respiratory Tract Infection in the Emergency Department

Ahmad A, Nor J, Abdullah AA, Tuan Kamauzaman TH, Yazid MB

Malays J Med Sci, 2021 Apr;28(2):72-83.
PMID: 33958962 DOI: 10.21315/mjms2021.28.2.7

Background: Emergency departments (EDs) are frequently misused for non-emergency cases such as upper respiratory tract infections (URTIs). Flooding of these cases may contribute to inappropriate antibiotic prescribing. The aim of this study was to determine the patient factors associated with inappropriate antibiotic prescribing for URTIs in the EDs.
Methods: This cross-sectional study involved patients over age 3 years old who presented with URTI to the green zone of the ED of a tertiary hospital on the east coast of Malaysia in 2018-2019. Convenient sampling was done. The patients were categorised into two groups according to their McIsaac scores: positive (≥ 2) or negative (< 2). Antibiotics given to the negative McIsaac group were considered inappropriate.
Results: A total of 261 cases were included - 127 with positive and 134 with negative McIsaac scores. The most common symptoms were fever and cough. About 29% had inappropriate antibiotic prescribing with a high rate for amoxycillin. Duration of symptoms of one day or less (OR 18.5; 95% CI: 1.65, 207.10; P = 0.018), presence of chills (OR 4.36; 95% CI: 1.13, 16.88; P = 0.033) and diagnosis of acute tonsillitis (OR 5.26; 95% CI: 1.76, 15.72; P = 0.003) were significantly associated with inappropriate antibiotic prescription.
Conclusion: Factors influencing inappropriate antibiotic prescribing should be pointed out to emergency doctors to reduce its incidence.

Serological and molecular detection of Strongyloides stercoralis infection among an Orang Asli community in Malaysia

Ahmad AF, Hadip F, Ngui R, Lim YA, Mahmud R

Parasitol Res, 2013 Aug;112(8):2811-6.
PMID: 23666229 DOI: 10.1007/s00436-013-3450-z

Detection of Strongyloides stercoralis infection particularly in asymptomatic individuals is often hampered due to the lack of standard diagnostic tools. In this study, the use of serological and molecular approaches were investigated for the detection of S. stercoralis infection among an Orang Asli (indigenous) community following a preliminary detection by microscopic examination of faecal samples. Out of 54 individuals studied, 17/54 (31.5%) were detected to be positive for S. stercoralis infection by enzyme-linked immunosorbent assay (ELISA), compared to 0/54 (0%) by faecal examination. Further confirmation performed by a nested polymerase chain reaction (PCR) using DNA extracted from faecal samples of these 17 individuals yielded 3/17 (17.6%) positives for S. stercoralis DNA amplification. No amplification was seen with the other 37 faecal samples, which were negative by microscopy and ELISA. As the high ELISA positive results were suspected to be false-positives, ELISA is not recommended for use as a detection tool but may be beneficial for evaluating the effectiveness of anti-Strongyloides drugs. The present finding indicated that PCR should be considered as an alternative diagnostic tool for the detection of S. stercoralis infection.
