    BACKGROUND: A tetravalent dengue vaccine demonstrated its protective efficacy in two phase III efficacy studies. Results from these studies were used to derive vaccination impact in the five Asian (Indonesia, Malaysia, Philippines, Thailand, Vietnam) and the five Latin American countries (Brazil, Colombia, Honduras, Mexico and Puerto Rico) participating in these trials.

    METHODS: Vaccination impact was investigated with an age-structured, host-vector, serotype-specific compartmental model. Parameters related to vaccine efficacy and levels of dengue transmission were estimated using data collected during the phase III efficacy studies. Several vaccination programs, including routine vaccination at different ages with and without large catch-up campaigns, were investigated.

    RESULTS: All vaccination programs explored translated into significant reductions in dengue cases at the population level over the first 10years following vaccine introduction and beyond. The most efficient age for vaccination varied according to transmission intensity and 9years was close to the most efficient age across all settings. The combination of routine vaccination and large catch-up campaigns was found to enable a rapid reduction of dengue burden after vaccine introduction.

    CONCLUSION: Our analysis suggests that dengue vaccination can significantly reduce the public health impact of dengue in countries where the disease is endemic.

    Sex steroids have been postulated to influence skin development and functions as well as its pathogenesis. MCC occurs in both sexes; however, the specific differences in pathogenesis among sexes have yet to be conclusively defined. The detailed status of sex steroid receptors (AR, PRA and PRB, and ERα, ERβ) are also unknown in MCC patients. We first immunolocalized sex steroid receptors and compared the results with immunolocalization of relevant transcription factors including SOX2, FOXA1, and Bcl-2 and Ki-67 in 18 cases of MCCs. AR, PRA, PRB, ERα, ERβ, Bcl-2, SOX2, and FOXA1 immunoreactivity was evaluated by using the modified H score method, and Ki-67 was quantified using labeling index. ERβ immunoreactivity was markedly present in all the cases of MCC examined, with relatively weak immunoreactivity of ERα, AR, PRA, and PRB. The status of ERβ immunoreactivity was also significantly correlated with Ki-67 labeling index and Bcl-2 score. These results demonstrated that ERβ could be associated with regulation of both cell proliferation and apoptosis in MCCs.

    BACKGROUND: There are currently limited data available on the patterns of opioid prescribing in Malaysia. This study investigated the patterns of opioid prescribing and characterized the dosing and duration of opioid use in patients with noncancer and cancer pain.
    METHODS: This retrospective, cross-sectional study was conducted at an outpatient hospital setting in Malaysia. All prescriptions for opioids (dihydrocodeine, fentanyl, morphine, and oxycodone) issued between January 2013 and December 2014 were examined. The number of prescriptions and patients, the distribution of mean daily dose, annual total days covered with opioids, and annual total opioid dose at the individual level were calculated and stratified by noncancer and cancer groups.
    RESULTS: A total of 1015 opioid prescriptions were prescribed for 347 patients from 2013 to 2014. Approximately 41.5% of patients (N = 144/347) and 58.5% (N = 203/347) were associated with noncancer and cancer diagnosis, respectively. Oxycodone (38.0%) was the highest prescribed primarily for the noncancer group. The majority of patients in both noncancer (74.3%) and cancer (60.4%) groups were receiving mean daily doses of < 50 mg morphine equivalents. The chronic use of opioids (> 90 days per year) was associated with 21.8% of patients in the noncancer group and 17.5% in the cancer group.
    CONCLUSIONS: The finding from this study showed that 41.5% of opioid users at an outpatient hospital setting in Malaysia received opioids for noncancer pain and 21.8% of these users were using opioids for longer than 90 days. The average daily dose in the majority of patients in both groups of noncancer and cancer was modest.

    BACKGROUND: Tick borne encephalitis (TBE) is an acute meningoencephalitis with or without myelitis caused by an RNA virus from the flavivirus family transmitted by Ixodes spp ticks. The neurotropic TBE virus infects preferentially large neurons in basal ganglia, anterior horns, medulla oblongata, Purkinje cells and thalamus. Brain metabolic changes related to radiologic and clinical findings have not been described so far.

    METHODS: Here we describe the clinical course of 10 consecutive TBE patients with outcome assessment at discharge and after 12 month using a modified Rankin Scale. Patients underwent cerebral MRI after confirmation of diagnosis and before discharge. (18)F-FDG PET/CT scans were performed within day 5 to day 14 after TBE diagnosis. Extended analysis of coagulation parameters by thrombelastometry (ROTEM® InTEM, ExTEM, FibTEM) was performed every other day after confirmation of TBE diagnosis up to day 10 after hospital admission or discharge.

    RESULTS: All patients presented with a meningoencephalitic course of disease. Cerebral MRI scans showed unspecific findings at predilection areas in 3 patients. (18)F-FDG PET/CT showed increased glucose utilization in one patient and decreased (18)F-FDG uptake in seven patients. Changes in coagulation measured by standard parameters and thrombelastometry were not found in any of the patients.

    DISCUSSION: Glucose hypometabolism was present in 7 out of 10 TBE patients reflecting neuronal dysfunction in predilection areas of TBE virus infiltration responsible for development of clinical signs and symptoms.

    Background Oral anticoagulant therapy is indicated for the prevention of stroke or other thromboembolic events. Premature discontinuation of oral anticoagulants may increase the risk of thromboembolism resulting in adverse sequelae. There are sparse data on the prevalence and the predictors of dabigatran discontinuation in Malaysian patients with atrial fibrillation. Objectives Determine the reasons and identify associated factors for abrupt discontinuation of dabigatran, assess the switching pattern and the occurrence of thromboembolic events after dabigatran discontinuation. Setting A university-affiliated tertiary hospital in Kuala Lumpur, Malaysia. Methods The clinical and demographic data of a cohort who were initiated with dabigatran between 2010 and 2012 at the University of Malaya Medical Centre were reviewed until the date of death or on 31st December 2013. Those patients who discontinued dabigatran were further followed up until 31st December 2015 to determine the occurrence of any thromboembolic event. Main outcome measure Permanent discontinuation of dabigatran for more than 8 weeks. Results 26 (14 %) of a cohort of 192 patients discontinued dabigatran therapy during a median follow-up period of 20 (range 3-45) months. About one-half of the discontinuation occurred within the first 6 months of dabigatran use. The three most cited reasons for discontinuation are bleeding events (19 %), high out-of-pocket drug payment (19 %) and cardioversion (19 %). Heart failure [adjusted odds ratio 3.699 (95 % confidence interval 1.393-9.574)] or chronic kidney disease [adjusted odds ratio 5.211 (95 % confidence interval 1.068-23.475)] were found to be independent risk factors for abrupt dabigatran discontinuation. Patients who discontinued dabigatran received warfarin (38 %), antiplatelet agents (16 %) or no alternative antithrombotic therapy (46 %). Five of the 26 patients who discontinued dabigatran developed an ischaemic stroke within 3-34 months after discontinuation. Conclusion Abrupt dabigatran discontinuation without an alternative oral anticoagulant increases the risk of thromboembolic events. As adverse drug events and renal impairment contribute substantially to the premature discontinuation of dabigatran, it is important to identify and monitor patients at risk to reduce dabigatran discontinuation rate especially during the first six months of dabigatran therapy.

    BACKGROUND: To assess the efficacy of antimicrobial photodynamic therapy (aPDT) or laser therapy (LT) alone as an adjunct to scaling and root planing (SRP) on the gingival crevicular fluid (GCF) inflammatory proteins in periodontal disease.

    METHODS: Databases (MEDLINE via PubMed; EMBASE; Cochrane Central Register of Controlled Trials and Cochrane Oral Health Group Trials Register databases) were searched from 1980 up to and including July 2016. The addressed PICO question was: "What effect does aPDT and/or LT as an adjunct to SRP have on the GCF inflammatory proteins in periodontal disease patients?"

    RESULTS: Eight studies used aPDT while 10 studies used laser alone. Eight cytokines including tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, IL-6, IL-8, IL-10, interferon gamma (IFN-γ), matrix metalloproteinase (MMP)-8 and granulocyte colony-stimulating factor (GM-CSF) were eligible for qualitative analysis for aPDT and LT studies. Four aPDT studies showed significant reduction in IL-1β while one study showed significant reduction in TNF-α levels after aPDT application at follow-up. One study showed significant reduction of IFN-γ, IL-8 and GM-CSF levels after aPDT at follow-up. IL-1β significantly reduced in 4 LT studies, while one study showed significant decrease for IL-6 and TIMP-1 levels. MMP-8 and TNF-α showed significant reduction in three and one study respectively.

    CONCLUSION: It remains debatable whether adjunctive aPDT or LT is effective in the reduction of GCF inflammatory proteins in periodontal disease due to non-standard laser parameters and short follow up period. These findings should be considered preliminary and further studies with long-term follow up and standardized laser parameters are recommended.

    The main purpose of the current article is to introduce a framework of the complexity of childhood obesity based on the family environment. A conceptual model that quantifies the relationships and interactions among parental socioeconomic status, family food security level, child's food intake and certain aspects of parental feeding behaviour is presented using the structural equation modeling (SEM) concept. Structural models are analysed in terms of the direct and indirect connections among latent and measurement variables that lead to the child weight indicator. To illustrate the accuracy, fit, reliability and validity of the introduced framework, real data collected from 630 families from Urumqi (Xinjiang, China) were considered. The framework includes two categories of data comprising the normal body mass index (BMI) range and obesity data. The comparison analysis between two models provides some evidence that in obesity modeling, obesity data must be extracted from the dataset and analysis must be done separately from the normal BMI range. This study may be helpful for researchers interested in childhood obesity modeling based on family environment.

    PURPOSE: This research characterised perioral muscle reciprocity and amplitude ratio in lower lip during bilabial syllable production [pa] at three rates to understand the neuromotor dynamics and scaling of motor speech patterns in individuals with Parkinson's disease (PD).

    METHOD: Electromyographic (EMG) signals of the orbicularis oris superior [OOS], orbicularis oris inferior [OOI] and depressor labii inferioris [DLI] were recorded during syllable production and expressed as polar-phase notations.

    RESULT: PD participants exhibited the general features of reciprocity between OOS, OOI and DLI muscles as reflected in the EMG during syllable production. The control group showed significantly higher integrated EMG amplitude ratio in the DLI:OOS muscle pairs than PD participants. No speech rate effects were found in EMG muscle reciprocity and amplitude magnitude across all muscle pairs.

    CONCLUSION: Similar patterns of muscle reciprocity in PD and controls suggest that corticomotoneuronal output to the facial nucleus and respective perioral muscles is relatively well-preserved in our cohort of mild idiopathic PD participants. Reduction of EMG amplitude ratio among PD participants is consistent with the putative reduction in the thalamocortical activation characteristic of this disease which limits motor cortex drive from generating appropriate commands which contributes to bradykinesia and hypokinesia of the orofacial mechanism.

    BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is an established pathogen that causes hospital- and community-acquired infections worldwide. The prevalence rate of MRSA infections were reported to be the highest in Asia. As there is limited epidemiological study being done in Malaysia, this study aimed to determine the prevalence of MRSA infection and the molecular characteristics of MRSA bacteraemia.

    METHODS: Two hundred and nine MRSA strains from year 2011 to 2012 were collected from a tertiary teaching hospital in Malaysia. The strains were characterized by antimicrobial susceptibility testing, staphylococcal cassette chromosome mec (SCCmec) typing, detection of Panton-Valentine leukocidin (PVL) gene, multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). Patient's demographic and clinical data were collected and correlated with molecular data by statistical analysis.

    RESULTS: Male gender and patient >50 years of age (p over the two-year study period were found to be genetically diverse.

    OBJECTIVES: The objectives of this study were to determine the prevalence and predictors of Pap smear screening among women aged 50 years and older.
    STUDY DESIGN: This cross-sectional study was conducted at two large urban health centres in Selangor. A total of 515 women aged 50 and older were recruited.
    RESULTS: The mean age of the respondents was 58.83±7.05, with a range of 50- 83 years. The prevalence of Pap smear screening was 39.22% (n=202). From the multivariate analysis, Pap smear screening was significantly associated with health care provider advice (adjusted odds ratio (AOR)=18.75; 95% CI=8.30, 42.37); tertiary (AOR=11.26; 95% CI=1.50, 84.68) and secondary education level (AOR=9.47; 95% CI=1.43, 62.84); use of contraception (AOR=2.90; 95% CI=1.48, 5.69); heart disease (AOR=0.22; 95% CI=0.05, 0.97); and worry about Pap smear results (AOR=0.20; 95% CI=0.09, 0.42).
    CONCLUSION: The prevalence of Pap smear screening in the older women is unsatisfactory. Health care provider advice, education level, use of contraception, heart disease and worry about Pap smear results were predictors of undergoing Pap smear screening in this study population.

    BACKGROUND: In out of hospital cardiac arrest (OHCA), the prognostic influence of conversion to shockable rhythms during resuscitation for initially non-shockable rhythms remains unknown. This study aimed to assess the relationship between initial and subsequent shockable rhythm and post-arrest survival and neurological outcomes after OHCA.

    METHODOLOGY: This was a retrospective analysis of all OHCA cases collected from the Pan-Asian Resuscitation Outcomes Study (PAROS) registry in 7 countries in Asia between 2009 and 2012. We included OHCA cases of presumed cardiac etiology, aged 18-years and above and resuscitation attempted by EMS. We performed multivariate logistic regression analyses to assess the relationship between initial and subsequent shockable rhythm and survival and neurological outcomes. 2-stage seemingly unrelated bivariate probit models were developed to jointly model the survival and neurological outcomes. We adjusted for the clustering effects of country variance in all models.

    RESULTS: 40,160 OHCA cases met the inclusion criteria. There were 5356 OHCA cases (13.3%) with initial shockable rhythm and 33,974 (84.7%) with initial non-shockable rhythm. After adjustment of baseline and prehospital characteristics, OHCA with initial shockable rhythm (odds ratio/OR=6.10, 95% confidence interval/CI=5.06-7.34) and subsequent conversion to shockable rhythm (OR=2.00,95%CI=1.10-3.65) independently predicted better survival-to-hospital-discharge outcomes. Subsequent shockable rhythm conversion significantly improved survival-to-admission, discharge and post-arrest overall and cerebral performance outcomes in the multivariate logistic regression and 2-stage analyses.

    CONCLUSION: Initial shockable rhythm was the strongest predictor for survival. However, conversion to subsequent shockable rhythm significantly improved post-arrest survival and neurological outcomes. This study suggests the importance of early resuscitation efforts even for initially non-shockable rhythms which has prognostic implications and selection of subsequent post-resuscitation therapy.

    OBJECTIVES: To pilot two new cognitive screening tools for use in an urban Malaysian population and to compare their criterion validity against a gold standard, the well-established Mini-Mental State Examination (MMSE).

    METHODS: The IDEA cognitive screen, Picture-based Memory Impairment Scale (PMIS), and MMSE were administered to a convenience sample of elderly (≥ 65 years) from the community and outpatient clinics at an urban teaching hospital. Consensus diagnosis was performed by two geriatricians blinded to PMIS and IDEA cognitive screen scores using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) clinical criteria. The MMSE performance was used as a reference.

    RESULTS: The study enrolled 66 participants, with a median age of 78.5 years (interquartile range [IQR], 72.5-83.0) years and 11.0 median years of education (IQR, 9.0-13.0). Forty-three (65.2%) were female, and 32 (48.4%) were Chinese. The area under the receiver operating characteristic (AUROC) curve values were .962 (IDEA cognitive screen), .970 (PMIS), and .935 (MMSE). The optimal cutoff values for sensitivity and specificity were: IDEA cognitive screen: ≤ 11, 90.9% and 89.7%; PMIS: ≤ 6, 97.3% and 69.0%; and MMSE: ≤ 23, 84.6% and 76.0%. Although the sample size was small, multivariable logistic regression modelling suggested that all three screen scores did not appear to be educationally biased.

    CONCLUSION: The IDEA and PMIS tools are potentially valid screening tools for dementia in urban Malaysia, and perform at least as well as the MMSE. Further work on larger representative, cohorts is needed to further assess the psychometric properties.

    CLINICAL IMPLICATIONS: Study provides alternative screening tools for dementia for both non-specialists and specialists.

    INTRODUCTION: Osteoporosis is a major health concern in postmenopausal women, and oxidative stress contributes to the development of bone loss. Cellular studies and ovariectomised rat model mimicking bone loss in postmenopausal women show the bone-protective effect of tocotrienols (TTs) with antioxidant capability. We aim to access the safety and efficacy of TT consumption for bone health in postmenopausal women.

    METHODS AND ANALYSIS: In this 12-week randomised double-blinded placebo-controlled trial for the effects of dietary TT supplementation in postmenopausal women, postmenopausal women aged 45 years and older with at least 1 year after menopause and bone mineral density T-score at the spine and/or hip 2.5 or more below the reference values will be randomly assigned to 3 daily supplements: (1) placebo group receiving 860 mg olive oil, (2) low TT group receiving 430 mg of 70% pure TTs (containing 300 mg TT) and (3) high TT group receiving 860 mg of 70% pure TTs (600 mg TT). The primary outcome measure will be urinary N-terminal telopeptide. The secondary outcome measures will be serum bone-specific alkaline phosphatase, receptor activator of nuclear factor-κB ligand, osteoprotegerin, urinary 8-hydroxy-2'-deoxyguanosine and quality of life. At 0, 6 and 12 weeks, the following will be assessed: (1) primary and secondary outcome measures; (2) serum TT and tocopherol concentrations; (3) physical activity and food frequency questionnaires. Liver function will be monitored every 6 weeks for safety. 'Intent-to-treat' principle will be employed for data analysis. A model of repeated measurements with random effect error terms will be applied. Analysis of covariance, χ2 analysis and regression will be used for comparisons.

    ETHICS AND DISSEMINATION: This study was approved by the Bioethics Committee of the Texas Tech University Health Sciences Center. The findings of this trial will be submitted to a peer-reviewed journal in the areas of bone or nutrition and international conferences.

    AIM: To determine the association between vitamin D and knee pain among participants of the Malaysian Elders Longitudinal Research (MELoR) study.

    METHOD: This was a cross-sectional study from the MELoR study consisting of a representative group of 1011 community-dwelling older persons (57% female), mean age 86.5 (54-94) years; 313 were Malays, 367 Chinese and 330 Indians. Participants were asked if they had knee pain. Levels of serum 25-hydroxy cholecalciferol (25-[OH]D), an indicator of vitamin D status, were measured using routine laboratory techniques.

    RESULTS: In unadjusted analysis, presence of knee pain was significantly associated with vitamin D deficiency (odds ratio [OR] 1.42; 95% confidence interval (CI) 1.08-1.85, P 0.011). Vitamin D levels were significantly associated with ethnicity differences where Malays (OR 7.08; 95% CI 4.94-10.15) and Indians (OR 6.10; 95% CI 4.28-9.71) have lower levels of vitamin D compared to Chinese. Subsequent multivariate analysis revealed that the association between vitamin D deficiency and knee pain was confounded by ethnic differences.

    CONCLUSION: A previous study suggested that vitamin D deficiency was associated with knee pain. This relationship was reproduced in our study, but we further established that the association was explained by ethnic variations. As vitamin D status is dependent on skin tone, diet and sunlight exposure, which are all effected by ethnicity, future studies are now required to determine whether a true relationship exists between vitamin D and knee pain.

    OBJECTIVE: The primary aim is to assess the efficacy of microcurrent, a form of electrical stimulation, as an adjunct therapy in accelerating healing in chronic wounds by reducing wound size and pain level. The secondary aim is to assess the qualitative changes in these parameters: inflammatory symptoms, vasodilation, sleep quality, gait and frequency of bowel movement.

    METHOD: Eligible patients with chronic wounds were enrolled between March and June 2016, from the Wound Care Unit, Hospital Kuala Lumpur in this consecutive case series. Standard wound care was performed with microcurrent as an adjunct therapy. Each patient was treated with an anti-inflammatory frequency, followed by a vasodilation frequency, while having their wounds cleansed during each dressing change. Patients were loaned a home-microcurrent device to treat themselves three times daily using a tissue repair frequency for four weeks.

    RESULTS: A total of 100 patients with chronic wounds, such as diabetic foot ulcers, venous leg ulcers, and pressure ulcers, were recruited. During the four-week treatment period, all patients had a reduction in wound size, with 16 having complete wound closure. All 89 of the 100 patients who complained of pain, associated with their wound, experienced reduced pain scores, with 11 being pain-free at the end of the four-week period. There was significant reduction (p<0.001) in both mean pain score and mean wound area during the treatment period, as well as improvements in other parameters, such as reduction in inflammatory symptoms (leg swelling, foot stiffness), increased vasodilation (skin discolouration, leg heaviness, early morning erection, sensation), improvement in sleep quality, gait, and frequency of bowel movement. No adverse events were reported.

    CONCLUSION: The results of this study show there was significant reduction in wound area and pain score during the treatment period. The ease of use of microcurrent devices would advocate its use in accelerating wound healing.

    BACKGROUND: Comorbidities are common in patients with heart failure (HF) and complicate treatment and outcomes. We identified patterns of multimorbidity in Asian patients with HF and their association with patients' quality of life (QoL) and health outcomes.

    METHODS AND FINDINGS: We used data on 6,480 patients with chronic HF (1,204 with preserved ejection fraction) enrolled between 1 October 2012 and 6 October 2016 in the Asian Sudden Cardiac Death in Heart Failure (ASIAN-HF) registry. The ASIAN-HF registry is a prospective cohort study, with patients prospectively enrolled from in- and outpatient clinics from 11 Asian regions (Hong Kong, Taiwan, China, Japan, Korea, India, Malaysia, Thailand, Singapore, Indonesia, and Philippines). Latent class analysis was used to identify patterns of multimorbidity. The primary outcome was defined as a composite of all-cause mortality or HF hospitalization within 1 year. To assess differences in QoL, we used the Kansas City Cardiomyopathy Questionnaire. We identified 5 distinct multimorbidity groups: elderly/atrial fibrillation (AF) (N = 1,048; oldest, more AF), metabolic (N = 1,129; obesity, diabetes, hypertension), young (N = 1,759; youngest, low comorbidity rates, non-ischemic etiology), ischemic (N = 1,261; ischemic etiology), and lean diabetic (N = 1,283; diabetic, hypertensive, low prevalence of obesity, high prevalence of chronic kidney disease). Patients in the lean diabetic group had the worst QoL, more severe signs and symptoms of HF, and the highest rate of the primary combined outcome within 1 year (29% versus 11% in the young group) (p for all <0.001). Adjusting for confounders (demographics, New York Heart Association class, and medication) the lean diabetic (hazard ratio [HR] 1.79, 95% CI 1.46-2.22), elderly/AF (HR 1.57, 95% CI 1.26-1.96), ischemic (HR 1.51, 95% CI 1.22-1.88), and metabolic (HR 1.28, 95% CI 1.02-1.60) groups had higher rates of the primary combined outcome compared to the young group. Potential limitations include site selection and participation bias.

    CONCLUSIONS: Among Asian patients with HF, comorbidities naturally clustered in 5 distinct patterns, each differentially impacting patients' QoL and health outcomes. These data underscore the importance of studying multimorbidity in HF and the need for more comprehensive approaches in phenotyping patients with HF and multimorbidity.

    BACKGROUND: Micra is a leadless pacemaker that is implanted in the right ventricle and provides rate response via a 3-axis accelerometer (ACC). Custom software was developed to detect atrial contraction using the ACC enabling atrioventricular (AV) synchronous pacing.

    OBJECTIVE: The purpose of this study was to sense atrial contractions from the Micra ACC signal and provide AV synchronous pacing.

    METHODS: The Micra Accelerometer Sensor Sub-Study (MASS) and MASS2 early feasibility studies showed intracardiac accelerations related to atrial contraction can be measured via ACC in the Micra leadless pacemaker. The Micra Atrial TRacking Using A Ventricular AccELerometer (MARVEL) study was a prospective multicenter study designed to characterize the closed-loop performance of an AV synchronous algorithm downloaded into previously implanted Micra devices. Atrioventricular synchrony (AVS) was measured during 30 minutes of rest and during VVI pacing. AVS was defined as a P wave visible on surface ECG followed by a ventricular event <300 ms.

    RESULTS: A total of 64 patients completed the MARVEL study procedure at 12 centers in 9 countries. Patients were implanted with a Micra for a median of 6.0 months (range 0-41.4). High-degree AV block was present in 33 patients, whereas 31 had predominantly intrinsic conduction during the study. Average AVS during AV algorithm pacing was 87.0% (95% confidence interval 81.8%-90.9%), 80.0% in high-degree block patients and 94.4% in patients with intrinsic conduction. AVS was significantly greater (P

    The aim of this study was to evaluate the relations of childhood trauma (CT) and obsessive-compulsive (OC) symptom dimensions to suicide ideation in patients with obsessive-compulsive disorder (OCD). Seventy OCD outpatients with lifetime suicide attempts and 60 controls were included. Participants completed the Scale for Suicide Ideation (SSI), the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Dimensional Obsessive-Compulsive Scale (DOCS) and the Depression Anxiety Stress Scales (DASS-21). Among OCD patients, 97.1% had current suicide ideation. OCD patients revealed higher scores on CT, suicide ideation, depression and anxiety than controls. The CT history of sexual abuse (SA) and OC symptom dimension of unacceptable thoughts explained suicide ideation. It was concluded that SA and unacceptable thoughts may contribute to high suicidality and have important implications for the assessment and treatment of suicide risk in OCD patients with lifetime suicide attempts.

    PURPOSE: Linked color imaging (LCI) by laser endoscopy is a novel narrow band light observation. In this study, we analyzed the efficacy of LCI for improving the various featured colorectal polyp's visibility utilizing a subjective endoscopist's visibility scoring and objective color difference (CD) value.

    METHODS: We retrospectively reviewed two pictures both with white light (WL) and LCI for 54 consecutive neoplastic polyps 2-20 mm in size. All pictures were evaluated by four endoscopists according to a published polyp visibility score from four (excellent visibility) to one (poor visibility). Additionally, we calculated CD value between each polyp and surrounding mucosa in LCI and WL using an original software.

    RESULTS: The mean polyp visibility scores of LCI (3.11 ± 1.05) were significantly higher than those of WL (2.50 ± 1.09, P

    INTRODUCTION: An ageing population has become an urgent concern for Asia in recent times. In nursing homes, polypharmacy has also become a compounding issue. Deprescribing practice is an evidence-based strategy to provide a better outcome in this group of patients; however, its implementation in nursing homes is often challenging, and prospective outcome data on deprescribing practice in the elderly is lacking. Our study assesses the implementation of team-care deprescribing to understand the benefits of this practice in geriatric setting and to explore the factors affecting deprescribing practice.

    METHODS AND ANALYSIS: This multicentre prospective study consists of a prestudy interview questionnaire, and a preintervention and postintervention study to be conducted in the nursing home setting on residents at least 65 years old and on five or more medications. We will employ a cluster randomised stepped-wedge interventional design, based on a five-step (reviewing, checking, discussion, communication and documentation) team-care deprescribing practice coupled with the use of a deprescribing guide (consisting of Beers and STOPP criteria, as well as drug interaction checking), to assess the health and pharmacoeconomic outcome in nursing homes' practice. Primary outcome measures of the intervention will consist of fall risks using a fall risk assessment tool. Other outcomes assessed include fall rates, pill burden including number of pills per day, number of doses per day and number of medications prescribed. Cost-related measures will include the use of cost-benefit analysis, which is calculated from the medication cost savings from deprescribing. For the prestudy interview questionnaire, findings will be analysed qualitatively using thematic analysis.

    ETHICS AND DISSEMINATION: This study is approved by the Domain Specific Review Board of National Healthcare Group, Singapore (2016/00422) and Monash University Human Research Ethics Committee (2016-1430-7791). The study findings shall be disseminated in international conferences and peer-reviewed publications. The study is registered with ClinicalTrials.gov (NCT02863341), Pre-results.
