    Introduction: Nurses are obligated to respond
    competently in the event of cardiac arrest. Nurses could
    be hesitant to intervene due to low self-efficacy in their
    ability to manage cardiac arrest patients.

    Objective: The objective of this study was to
    determine the level of nurses' perceived self-efficacy
    in cardiopulmonary resuscitation (CPR) at a private
    hospital in Kuala Lumpur.

    Method: A cross-sectional descriptive study was
    conducted with 112 respondents who fulfilled the
    inclusion criteria. A 19 item questionnaire on
    Resuscitation Self-Efficacy Scale (RSES) was adapted
    and scored using a 5-point Likert scale.

    Results: The total mean score and standard deviation
    of perceived self-efficacy score in resuscitation was (M
    = 77.68; SD ± 11.77) which indicated a high degree
    of self-efficacy among nurses. There were significant
    differences between respondents’ age groups with (t
    = -2.520; p = 0.013), unit of working (t = -4.086; p =
    0.001), real experiences in resuscitation (t = 2.532; p =
    0.013), and the number of participations in resuscitation
    (t=-6.668; p=0.001) and nurses perceived self-efficacy
    in CPR. There were also significant differences between
    respondents' years of working experience with (F
    = 7.286; p =0.001) and types of last resuscitation
    training (F= 7.088; p = 0.001). However, there was no
    significant difference between the nurses' time of their
    last resuscitation training (F = 1.225; p = 0.298) and the
    nurses perceived self-efficacy in CPR.

    Conclusion: In conclusion, nurses were deemed to possess
    a high sense of self-efficacy in CPR. This study concluded
    that nurses' age groups, years of working experience,
    unit of working, real experiences in resuscitation and
    the number of participations in resuscitation and types
    of last resuscitation training are factors contributing
    towards self-efficacy in CPR performances. However, the
    time of last resuscitation training reported no significant
    difference towards nurses' perceived self-efficacy in
    CPR. Therefore, repetitive CPR and ACLS certification
    training are pivotal in order to strengthen nurse’s self-efficacy in resuscitation and team collaboration through
    training in this private hospital.

    Introduction: The prevalence of cataract surgeries
    ranges from 7 to 12 million cases in 2000, 20 million
    in 2010 and an estimation of 32 million cataract
    surgeries annually by the year 2020 worldwide (WHO,
    2015). Traditionally, the healthcare providers were
    only able to give health education before the patient
    is discharged from the healthcare setting while followup
    can only be done when the patient comes for their
    follow-up. But most of the patients will remain confused
    or had forgotten about the post-operative care even
    after receiving a comprehensive discharge preparation.
    However, with the advancement of technologies in
    this modern era, nurse-led telephone follow-up can be
    considered as a tool to assist healthcare providers in the
    follow-up care in Malaysia. On the same note, a private
    eye specialist organisation with centres throughout
    Malaysia, had taken the initiative to provide telephone
    follow-up service for their patients with three main
    objectives namely, to provide pre- and post-education
    on cataract surgery, to detect early post cataract surgery
    complications as well as to minimise anxiety among
    their patients. However, till date no patient feedback
    regarding the service was conducted.

    Objective: The research objective for this study was to
    determine patient’s level of satisfaction with the nurseled
    telephone follow-up after cataract surgery at a private
    eye specialist centre in Penang.

    Method: A cross sectional quantitative descriptive study
    design was used to study ninety post cataract patients in
    a private hospital, Penang through universal sampling
    method. A validated self-developed questionnaire based
    on the three main objectives of the telephone follow-up
    service was used for this study.

    Results: Overall, the level of patient’s satisfaction with
    nurse-led telephone follow-up after cataract surgery at
    a private eye specialist centre in Penang was high (49.9
    ±4.85) especially for the health education provided
    (4.18 ±0.21) followed by the effort to detect early
    complications (4.16 ±0.12) and to minimise patients’
    anxiety level (4.16 ±0.12).

    Amoebiasis is a parasitic infection caused by the
    intestinal protozoan Entamoeba histolytica, most
    prevalent in developing countries. It results in 40,000 to
    100,000 deaths each year from amoebic colitis and extra
    intestinal infections. Amoebic liver abscess (ALA)
    is the most common extra intestinal site of infection
    with an incidence of between 3% and 9% of all cases of
    amoebiasis. Ultrasound which has a sensitivity of more
    than 90% for detecting ALA is highly recommended
    as an initial investigation followed by serological
    demonstration of circulating antibodies specific to
    Entamoeba histolytica.

    Cervical spine injury is commonly associated with
    road-traffic accidents. The true incidence of cervical
    spine injuries is unknown due to under-reporting of
    such injuries. Cervical spine injury is associated with
    high morbidity and mortality if it is missed. With the
    advancement of imaging modalities, the number of
    missed cervical injuries has reduced. Nevertheless, some
    clinicians are dependent solely on imaging tools to rule
    out cervical spine injury in a trauma victim. We report
    two cases of “near miss” C6 fracture to highlight the
    importance of a detailed clinical history and clinical
    examination with imaging as an adjunct to rule out
    cervical injury.

    Tumoral calcinosis is an uncommon condition which has been described to exist in primary and secondary forms. A lack of awareness of this entity can lead to unnecessary procedures and incorrect management. We report a case of a patient on peritoneal dialysis who presented with multiple painful joint swellings to the orthopaedic department. An initial diagnosis of septic arthritis was made, then revised to chronic tophaceous gout and referred to the rheumatology unit.

    Introduction: It is still a challenge that the
    dissecting room has a place in learning gross anatomy.
    Understanding the students’ preference of learning
    tools is important to devise alternative teaching aids
    for improvement in learning anatomy. This study was
    conducted to assess student’s preference of learning tools
    available in the anatomy laboratory of an integrated
    curriculum.

    Methods: A cross-sectional comparative study was
    carried out for 4 weeks among 741 medical and dental
    students of International Islamic University Malaysia
    (IIUM), Universiti Teknologi MARA (UiTM),
    University Sabah Malaysia (UMS) and University
    Malaysia Sarawak (UNIMAS). Pre-tested, semistructured,
    self-administrated questionnaires including
    open-ended questions were distributed. The data were
    analyzed by using SPSS 17.

    Results: Most of the participants were Malays (86%) and
    female (67%). The students from IIUM, UiTM, UMS
    and UNIMAS preferred the plastic model in terms of
    handability and application in examination (OSPE). It was

    Human risk allele carriers of Lysine-Specific Demethylase 1 (LSD1) and LSD1 deficient mice have salt sensitive hypertension for unclear reasons. We hypothesized that LSD1 deficiency causes dysregulation of aldosterone's response to salt intake resulting in increased cardiovascular risk factors [blood pressure and microalbumin]. Furthermore, we determined the effect of biological sex on these potential abnormalities. To test our hypotheses, LSD1 male and female heterozygote knockout (LSD1+/-) and wild type (WT) mice were assigned to two age groups: 18 weeks and 36 weeks. Plasma aldosterone levels and aldosterone production from zona glomerulosa cells studied ex vivo were greater in both male and female LSD1+/- mice consuming a liberal salt diet as compared to WT mice consuming the same diet. However, salt sensitive blood pressure elevation and increased microalbuminuria were only observed in male LSD1+/- mice. These data suggest that LSD1 interacts with aldosterone's secretory response to salt intake. Lack of LSD1 causes inappropriate aldosterone production on a liberal salt diet; males appear to be more sensitive to this aldosterone increase as males, but not females, develop salt sensitivity of blood pressure and increased microalbuminuria. The mechanism responsible for the cardiovascular protective effect in females is uncertain but may be related to estrogen modulating the effect of mineralocorticoid receptor activation.

    OBJECTIVE: This study reports the results from a 5-year longitudinal investigation of the prevalence and severity of cognitive deficits following significant (i.e., ventilation required for > 24 hours) traumatic brain injury. The changes in performance, either improvement or decline, across five domains of cognitive functioning are described.

    METHOD: A group of 56 adults was assessed at approximately 6 months, 1 year, and 5 years following injury.

    RESULTS: Impairment was evident on all measures but prevalence and rate of improvement varied. Overall, by 5 years post-injury over 85% of patients were not impaired on measures of general intelligence, simple attention, and visual perception. However, 28% of patients continued to show some degree of impairment on complex attention and verbal fluency, and performance on verbal memory remained impaired for 60% of patients. There was also evidence for deterioration in complex attention and verbal memory between 1 year and 5 years. ANOVAs showed that improvement occurred on most measures between 6 months and 1 year, but there was both improvement and decline on some measures between 1 year and 5 years.

    CONCLUSIONS: The findings show that there is considerable heterogeneity in cognitive outcome following TBI, with some deterioration evident over the long term.

    Bariatric surgery is currently the most durable weight loss solution for patients with morbid obesity. The extent of weight loss achieved, however, is subject to variation due to various factors, including patients' behaviour. In this study, we aimed to identify pre- and post-surgical predictors of weight loss following bariatric surgery. This prospective study included 57 participants who went through bariatric surgery (laparoscopic Roux-en-Y gastric bypass: n = 30; laparoscopic sleeve gastrectomy: n = 23; one anastomosis gastric bypass-mini gastric bypass: n = 4) in two tertiary referral hospitals. Consenting participants were assessed prior to surgery (T₀), and three months (T₁) and six months (T₂) after surgery. The assessment included interview and anthropometric measurements. The interview was done with the aid of instruments, including the Hospital Anxiety and Depression Scale (HADS) for anxiety and depression screening and the Dutch Eating Behaviour Questionnaire (DEBQ) for eating behaviour assessment. Baseline comorbidity status was obtained from medical records. A Generalised Estimating Equation (GEE) was developed to determine predictors of weight loss. Participants in the study were mostly women (n = 37, 65%) with a mean age of 39.4 (SD = 10.01) years. The mean excess BMI loss (EBMIL) and total weight loss (TWL) at the sixth month was 63.31% and 23.83%, respectively. Anxiety, depression, and external eating scores reduced over time. Advancing age, high BMI, and higher scores for emotional and external eating emerged as significant negative predictors for TWL%. It can be concluded that the patients experienced substantial weight loss after surgery. Continuous monitoring of psychological well-being and eating behaviour are essential for optimal weight loss.

    BACKGROUND: A Malay version of Parent Satisfaction Scale (PSS-M) is needed to investigate the factors contributing to the Malay caregivers' satisfaction with health care management for children with autism spectrum disorder (ASD). The aim of the study is to translate and validate the questionnaire to assess the caregivers' satisfaction on health care services.

    METHODS: A cross-sectional study was conducted among 110 caregivers of children with ASD aged between 2 and 17 years old that received treatment at two tertiary care centres in Kelantan. Permission to use the original version of the PSS questionnaire was obtained. The original English version of the PSS was translated into a Malay version following the 10 steps proposed by an established guideline. Pre-testing of the PSS was carried out with 30 caregivers before confirmatory factor analysis (CFA) was established using 110 caregivers. They were asked to assess their understanding of the questionnaire. The one-dimensional questionnaire consists of 11 items, including staff attitudes, availability of staff, supportiveness, and helpfulness. The 5-point Likert scale provided ratings from 1 (strongly disagree) to 5 (strongly agree). Confirmatory factor analysis was performed using a robust maximum likelihood estimator.

    RESULTS: The analysis showed model fit data with good reliability.

    CONCLUSION: The PSS-M shows overall model fitness based on specific indices, with good construct validity and excellent absolute reliability to determine the satisfaction level of caregivers of children with ASD with respect to health care services.

    The principal objective of this research work was to investigate the results of impregnating epoxy matrix-glass fibre composite laminates with nanosilica as secondary reinforcement. 0.5, 0.75, 1 and 3 wt% nanosilica was used and thereafter properties of composites were assessed through tensile, three point bending, quasi static indentation tests and dynamic mechanical analysis. Scanning electron microscope examinations were done on fracture surfaces and failure modes were analyzed. The internal failures of the composite due to quasi-static indentation were evaluated through C-Scan. Among samples of different weight fractions, 0.75 wt% nanosilica reinforced composite laminates exhibited substantial increase of 42% in tensile strength and 39.46% in flexural strength. The reduction in glass transition temperature (Tg), increase in storage modulus (E'), loss modulus (E″) and damping factor (tan δ) were also observed. Quasi-static indentation assessments revealed that energy absorption property was enhanced significantly by 53.97%. Hence nanosilica up to 0.75 wt% can be used as a potential candidate for secondary reinforcement in epoxy composite laminates.

    The main objective of this research was to introduce a novel machine learning algorithm of alternating decision tree (ADTree) based on the multiboost (MB), bagging (BA), rotation forest (RF) and random subspace (RS) ensemble algorithms under two scenarios of different sample sizes and raster resolutions for spatial prediction of shallow landslides around Bijar City, Kurdistan Province, Iran. The evaluation of modeling process was checked by some statistical measures and area under the receiver operating characteristic curve (AUROC). Results show that, for combination of sample sizes of 60%/40% and 70%/30% with a raster resolution of 10 m, the RS model, while, for 80%/20% and 90%/10% with a raster resolution of 20 m, the MB model obtained a high goodness-of-fit and prediction accuracy. The RS-ADTree and MB-ADTree ensemble models outperformed the ADTree model in two scenarios. Overall, MB-ADTree in sample size of 80%/20% with a resolution of 20 m (area under the curve (AUC) = 0.942) and sample size of 60%/40% with a resolution of 10 m (AUC = 0.845) had the highest and lowest prediction accuracy, respectively. The findings confirm that the newly proposed models are very promising alternative tools to assist planners and decision makers in the task of managing landslide prone areas.

    BACKGROUND: Amyloidosis is a disorder caused by extracellular tissue deposition of insoluble fibrils which may result in a wide spectrum of symptoms depending upon their types, sites and amount of deposition. Amyloidosis can be divided into either systemic or localized disease.

    CASE PRESENTATION: We present a case of a middle-aged gentleman who presented with persistent nephrotic syndrome with worsening renal function. Repeated renal biopsies showed the presence of renal-limited AL amyloidosis. Systemic amyloidosis workup was unremarkable apart from a slightly raised band of IgG lambda level with no associated immunoparesis. The nephrotic syndrome and renal histology did not improve over a 3-year period despite being given two courses of chemotherapies.

    CONCLUSION: We hope that early recognition of this unusual localised presentation of renal- limited AL Amyloidosis and its poor response to conventional treatment can alert the nephrologist to the potential existence of this rare condition.

    Neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease, are becoming more prevalent and an increasing burden on society. Neurodegenerative diseases often arise in the milieu of neuro-inflammation of the brain. Reactive astrocytes are key regulators in the development of neuro-inflammation. This study describes the effects of Palm Fruit Bioactives (PFB) on the behavior of human astrocytes which have been activated by IL-1β. When activated, the astrocytes proliferate, release numerous cytokines/chemokines including TNFα, RANTES (CCL5), IP-10 (CXCL10), generate reactive oxygen species (ROS), and express specific cell surface biomarkers such as the Intercellular Adhesion Molecule (ICAM), Vascular Cellular Adhesion Molecule (VCAM) and the Neuronal Cellular Adhesion Molecule (NCAM). Interleukin 1-beta (IL-1β) causes activation of human astrocytes with marked upregulation of pro-inflammatory genes. We show significant inhibition of these pro-inflammatory processes when IL-1β-activated astrocytes are exposed to PFB. PFB causes a dose-dependent and time-dependent reduction in specific cytokines: TNFα, RANTES, and IP-10. We also show that PFB significantly reduces ROS production by IL-1β-activated astrocytes. Furthermore, PFB also reduces the expression of ICAM and VCAM, both in activated and naïve human astrocytes in vitro. Since reactive astrocytes play an essential role in the neuroinflammatory state preceding neurodegenerative diseases, this study suggests that PFB may have a potential role in their prevention and/or treatment.

    Background: Tasks requiring simultaneous mobility and cognition (dual tasks) have been associated with incidence of falls. Although these deficits have been documented in individuals with neurologic disorder, the effect of dual task in children with traumatic brain injury has not been fully explored.

    Objective: To investigate the effect of dual-task (dual-motor and dual-cognitive task) conditions on spatiotemporal gait parameters during timed up and go test in children with traumatic brain injury.

    Methods and Material: A total of 14 children with traumatic brain injury and 21 typically developing children participated in this case-control study. Functional balance was assessed before the actual testing to predict the risk of falls. Timed up and go test was performed under single-task and dual-task (dual-motor and dual-cognitive task) conditions. Spatiotemporal gait parameters were determined using the APDM Mobility Lab system. The descriptive statistics and t-test were used to analyze demographic characteristics and repeated measure ANOVA test was used to analyze the gait parameters.

    Results: Under dual-task (dual-motor and dual-cognitive task) conditions during the timed up and go test, gait performance significantly deteriorated. Furthermore, the total time to complete the timed up and go test, stride velocity, cadence, and step time during turning were significantly different between children with traumatic brain injury and typically developing children.

    Conclusions: These findings suggest that gait parameters were compromised under dual-task conditions in children with traumatic brain injury. Dual-task conditions may become a component of gait training to ensure a complete and comprehensive rehabilitation program.

    This article aims at providing an insight to the clinical modifications required for the endodontic management of severely dilacerated mandibular third molar. A 35-year-old patient was referred for the root canal treatment of the mandibular left third molar. An intraoral periapical radiograph revealed a severe curvature in both the canals. A wide trapezoidal access was prepared following the use of intermediate-sized files for apical preparation. Owing to increased flexibility, Hero Shaper NITI files were used for the biomechanical preparation and single cone obturation was carried out. Third molars owing to their most posterior location-limited access coupled with a severe curvature pose utmost clinical challenges require meticulous skill, advanced technology, and patience to achieve success.

    Background: Atopic dermatitis (AD) is a common skin condition among Asians. Recent studies have shown that Asian AD has a unique clinical and immunologic phenotype compared with European/American AD.

    Objective: The Asian Academy of Dermatology and Venereology Expert Panel on Atopic Dermatitis developed this reference guide to provide a holistic and evidence-based approach in managing AD among Asians.

    Methods: Electronic searches were performed to retrieve relevant systematic reviews and guidelines on AD. Recommendations were appraised for level of evidence and strength of recommendation based on the U.K. National Institute for Health and Care Excellence and Scottish Intercollegiate Guidelines Network guidelines. These practice points were based on the consensus recommendations discussed during the Asia Pacific Meeting of Experts in Dermatology held in Bali, Indonesia in October 2016 and April 2017.

    Results: The Expert Panel recommends an approach to treatment based on disease severity. The use of moisturizers is recommended across all levels of AD severity, while topical steroids are recommended only for flares not controlled by conventional skin care and moisturizers. Causes of waning efficacy must be explored before using topical corticosteroids of higher potency. Topical calcineurin inhibitors are recommended for patients who have become recalcitrant to steroid, in chronic uninterrupted use, and when there is steroid atrophy, or when there is a need to treat sensitive areas and pediatric patients. Systemic steroids have a limited role in AD treatment and should be avoided if possible. Educational programs that allow a patient-centered approach in AD management are recommended as an adjunct to conventional therapies. Recommendations on the use of phototherapy, systemic drugs, and emerging treatments are also included.

    Conclusion: The management of AD among Asians requires a holistic approach, integrating evidence-based treatments while considering accessibility and cultural acceptability.

    Cell contact formation, which is the process by which cells are brought into close proximity is an important biotechnological process in cell and molecular biology. Such manipulation is achieved by various means, among which dielectrophoresis (DEP) is widely used due to its simplicity. Here, we show the advantages in the judicious choice of the DEP microelectrode configuration in terms of limiting undesirable effects of dielectric heating on the cells, which could lead to their inactivation or death, as well as the possibility for cell clustering, which is particularly advantageous over the linear cell chain arrangement typically achieved to date with DEP. This study comprises of experimental work as well as mathematical modeling using COMSOL. In particular, we establish the parameters in a capillary-based microfluidic system giving rise to these optimum cell-cell contact configurations, together with the possibility for facilitating other cell manipulations such as spinning and rotation, thus providing useful protocols for application into microfluidic bioparticle manipulation systems for diagnostics, therapeutics or for furthering research in cellular bioelectricity and intercellular interactions.

    It has been quite a challenge to diagnose Mild Cognitive Impairment due to Alzheimer's disease (MCI) and Alzheimer-type dementia (AD-type dementia) using the currently available clinical diagnostic criteria and neuropsychological examinations. As such we propose an automated diagnostic technique using a variant of deep neural networks language models (DNNLM) on the verbal utterances of affected individuals. Motivated by the success of DNNLM on natural language tasks, we propose a combination of deep neural network and deep language models (D2NNLM) for classifying the disease. Results on the DementiaBank language transcript clinical dataset show that D2NNLM sufficiently learned several linguistic biomarkers in the form of higher order n-grams to distinguish the affected group from the healthy group with reasonable accuracy on very sparse clinical datasets.

    Markov map is one example of interval maps where it is a piecewise expanding
    map and obeys the Markov property. One well-known example of Markov map is the
    doubling map, a map which has two subintervals with equal partitions. In this paper, we
    are interested to investigate another type of Markov map, the so-called skewed doubling
    map. This map is a more generalized map than the doubling map. Thus, the aims of this
    paper are to find the fixed points as well as the periodic points for the skewed doubling
    map and to investigate the sensitive dependence on initial conditions of this map. The
    method considered here is the cobweb diagram. Numerical results suggest that there exist
    dense of periodic orbits for this map. The sensitivity of this map to initial conditions is
    also verified where small differences in initial conditions give different behaviour of the
    orbits in the map.
