    BACKGROUND: Severity assessments of respiratory tract infection (RTI) in children are known to differ between parents and clinicians, but determinants of perceived severity are unknown.

    AIM: To investigate the (dis)agreement between, and compare the determinants of, parent and clinician severity scores.

    DESIGN AND SETTING: Secondary analysis of data from a prospective cohort study of 8394 children presenting to primary care with acute (≤28 days) cough and RTI.

    METHOD: Data on sociodemographic factors, parent-reported symptoms, clinician-reported findings, and severity assessments were used. Kappa (κ)-statistics were used to investigate (dis) agreement, whereas multivariable logistic regression was used to identify the factors associated with illness severity.

    RESULTS: Parents reported higher illness severity (mean 5.2 [standard deviation (SD) 1.8], median 5 [interquartile range (IQR) 4-7]), than clinicians (mean 3.1 [SD 1.7], median 3 [IQR 2-4], P<0.0001). There was low positive correlation between these scores (+0.43) and poor inter-rater agreement between parents and clinicians (κ 0.049). The number of clinical signs was highly correlated with clinician scores (+0.71). Parent-reported symptoms (in the previous 24 hours) that were independently associated with higher illness severity scores, in order of importance, were: severe fever, severe cough, rapid breathing, severe reduced eating, moderate-to-severe reduced fluid intake, severe disturbed sleep, and change in cry. Three of these symptoms (severe fever, rapid breathing, and change in cry) along with inter/subcostal recession, crackles/crepitations, nasal flaring, wheeze, and drowsiness/irritability were associated with higher clinician scores.

    CONCLUSION: Clinicians and parents use different factors and make different judgements about the severity of children's RTI. Improved understanding of the factors that concern parents could improve parent-clinician communication and consultation outcomes.

    BACKGROUND: Severe dengue infection often has unpredictable clinical progressions and outcomes. Obesity may play a role in the deterioration of dengue infection due to stronger body immune responses. Several studies found that obese dengue patients have a more severe presentation with a poorer prognosis. However, the association was inconclusive due to the variation in the results of earlier studies. Therefore, we conducted a systematic review and meta-analysis to explore the relationship between obesity and dengue severity.

    METHODS: We performed a systematic search of relevant studies on Ovid (MEDLINE), EMBASE, the Cochrane Library, Web of Science, Scopus and grey literature databases. At least two authors independently conducted the literature search, selecting eligible studies, and extracting data. Meta-analysis using random-effects model was conducted to compute the pooled odds ratio with 95% confidence intervals (CI).

    FINDINGS: We obtained a total of 13,333 articles from the searches. For the final analysis, we included a total of fifteen studies among pediatric patients. Three cohort studies, two case-control studies, and one cross-sectional study found an association between obesity and dengue severity. In contrast, six cohort studies and three case-control studies found no significant relationship between obesity and dengue severity. Our meta-analysis revealed that there was 38 percent higher odds (Odds Ratio = 1.38; 95% CI:1.10, 1.73) of developing severe dengue infection among obese children compared to non-obese children. We found no heterogeneity found between studies. The differences in obesity classification, study quality, and study design do not modify the association between obesity and dengue severity.

    CONCLUSION: This review found that obesity is a risk factor for dengue severity among children. The result highlights and improves our understanding that obesity might influence the severity of dengue infection.

    The Vertigo symptom scale (VSS) is a well established tool for the evaluation of vestibular disorders and the associated symptoms of autonomic arousal and somatosensation. By using a validated Malay version of vertigo symptom scale (MVVSS) questionnaire, the severity of the vertigo from patients' perspective can be determined and rated. Before MVVSS can be applied clinically among Malaysians, it was of interest to determine its clinical value in identifying vestibular disorders.

    OBJECTIVE: The Asthma Insights and Reality in Asia-Pacific (AIRIAP) survey collected detailed information on asthma severity and management in the urban centres of eight areas of the Asia-Pacific region. This study compared asthma morbidity and management practices in these areas.
    METHODOLOGY: Following recruitment, face-to-face interviews were completed with 2323 adults with diagnosed asthma, who had current symptoms or were using asthma medication. Comparisons between areas were made for asthma severity, asthma burden and management practices.
    RESULTS Asthma severity varied significantly between areas (P < 0.01), with Vietnam and mainland China reporting the most cases with severe, persistent symptoms. Severity of asthma was significantly associated with advancing age and a lower level of education in a multivariate analysis (P < 0.001). The total use of acute healthcare for asthma was significantly associated with increased asthma severity. Work absence due to asthma was highest in the Philippines (46.6%) and lowest in South Korea (7.5%). The use of inhaled corticosteroids was associated with age in a non-linear manner. There was significant variation among countries in usage of inhaled corticosteroids, from 1.3% in South Korea to 29.0% in Taiwan (P < 0.00001). A peak flow meter was owned by a total of 7.7% of respondents, and overall, 17.9% of adults had a written action plan for asthma management.
    CONCLUSIONS: Within the Asia-Pacific region, asthma in adults differs significantly in disease severity, management and treatment according to area of residence. International recommendations on the management of asthma are generally not being followed.

    INTRODUCTION: There is limited data on the effects of low carbohydrate diets on renal outcomes particularly in patients with underlying diabetic kidney disease. Therefore, this study determined the safety and effects of very low carbohydrate (VLCBD) in addition to low protein diet (LPD) on renal outcomes, anthropometric, metabolic and inflammatory parameters in patients with T2DM and underlying mild to moderate kidney disease (DKD).

    MATERIALS AND METHODS: This was an investigator-initiated, single-center, randomized, controlled, clinical trial in patients with T2DM and DKD, comparing 12-weeks of low carbohydrate diet (<20g daily intake) versus standard low protein (0.8g/kg/day) and low salt diet. Patients in the VLCBD group underwent 2-weekly monitoring including their 3-day food diaries. In addition, Dual-energy x-ray absorptiometry (DEXA) was performed to estimate body fat percentages.

    RESULTS: The study population (n = 30) had a median age of 57 years old and a BMI of 30.68kg/m2. Both groups showed similar total calorie intake, i.e. 739.33 (IQR288.48) vs 789.92 (IQR522.4) kcal, by the end of the study. The VLCBD group showed significantly lower daily carbohydrate intake 27 (IQR25) g vs 89.33 (IQR77.4) g, p<0.001, significantly higher protein intake per day 44.08 (IQR21.98) g vs 29.63 (IQR16.35) g, p<0.05 and no difference in in daily fat intake. Both groups showed no worsening of serum creatinine at study end, with consistent declines in HbA1c (1.3(1.1) vs 0.7(1.25) %) and fasting blood glucose (1.5(3.37) vs 1.3(5.7) mmol/L). The VLCBD group showed significant reductions in total daily insulin dose (39(22) vs 0 IU, p<0.001), increased LDL-C and HDL-C, decline in IL-6 levels; with contrasting results in the control group. This was associated with significant weight reduction (-4.0(3.9) vs 0.2(4.2) kg, p = <0.001) and improvements in body fat percentages. WC was significantly reduced in the VLCBD group, even after adjustments to age, HbA1c, weight and creatinine changes. Both dietary interventions were well received with no reported adverse events.

    CONCLUSION: This study demonstrated that dietary intervention of very low carbohydrate diet in patients with underlying diabetic kidney disease was safe and associated with significant improvements in glycemic control, anthropometric measurements including weight, abdominal adiposity and IL-6. Renal outcomes remained unchanged. These findings would strengthen the importance of this dietary intervention as part of the management of patients with diabetic kidney disease.

    The value of image cytometry DNA ploidy analysis and dysplasia grading to predict malignant transformation has been determined in oral lesions considered to be at 'high' risk on the basis of clinical information and biopsy result. 10-year follow up data for 259 sequential patients with oral lesions clinically at 'high' risk of malignant transformation were matched to cancer registry and local pathology database records of malignant outcomes, ploidy result and histological dysplasia grade. In multivariate analysis (n = 228 patients), 24 developed carcinoma and of these, 14 prior biopsy samples were aneuploid. Aneuploidy was a significant predictor (hazard ratio 7.92; 95% CI 3.45, 18.17) compared with diploidy (p

    INTRODUCTION: Cognitive dysfunction has been significantly associated with functional impairment in patients with major depressive disorder (MDD).

    METHODS: This is a subgroup analysis of 211 Malaysian patients recruited from the multicountry, multicenter, cross-sectional Cognitive Dysfunction in Asian patients with Depression (CogDAD) study. Depression severity, cognitive dysfunction, and functional disability were assessed and compared with the overall CogDAD study population. Factors associated with functional disability were also evaluated in this Malaysian patient population.

    RESULTS: Approximately half of the Malaysian patients were in their first depressive episode, with the majority being treated for mild-to-moderate depression. Furthermore, Malaysian patients experienced cognitive dysfunction, with self-reported Perceived Deficits Questionnaire (PDQ-D) scores falling within the third quartile of PDQ-D severity. Malaysian patients also reported functional disability evidenced by a mean total Sheehan Disability Scale (SDS) score of 11.47 ± 6.68, with the highest SDS score reported in the "Social Life/Leisure Activities" domain. Compared with the overall CogDAD study population, the Malaysian patient population had comparable patient demographics in terms of marital and working status; outcome scores for PHQ-9 (9-item Patient Health Questionnaire for self-reported depression severity), PDQ-D and SDS; and worst perceived cognitive dysfunction reported in the "Attention/Concentration" domain. Factors found to be significantly associated with functional disability were PDQ-D score, sick leave taken, and antidepressant treatment (P

    Screening for proteinuria and hematuria is important in the prevention of chronic renal disease. In Malaysia to date no such attempt has been made to establish the prevalence of proteinuria and hematuria. A total of 45,149 primary school children from three districts in Kelantan were screened for proteinuria and hematuria. They were 23,289 boys and 21,860 girls. The prevalence of abnormal urinary sediments after third screening was 0.17% ie 0.07% were in boys and 0.10% were in girls. The commonest abnormality was proteinuria (0.12%), followed by hematuria (0.03%) and combination of proteinuria and hematuria (0.02%). Hematuria was more commonly seen in girls compared to boys while proteinuria was seen in almost equal proportion in boys and girls. Despite screening large number of children the prevalence of asymptomatic proteinuria and hematuria was far lower than in an earlier reported study. Furthermore the majority had mild abnormalities.

    A recent genome-wide copy number (CNV) scan identified a 13q12.11 duplication in the exportin-4 (XPO4) gene to be associated with non-alcoholic steatohepatitis (NASH). We sought to confirm the finding in a larger cohort and to assess the serum XPO4 pattern in a broad spectrum of non-alcoholic fatty liver disease (NAFLD) cases. We analysed 249 NAFLD patients and 232 matched controls using TaqMan assay and serum XPO4 was measured. Copy number distribution was as follows: copy number neutral (NAFLD: 53.8%, controls: 68.6%), copy number losses (NAFLD: 13.3%, controls: 12.9%), copy number gains (NAFLD: 32.9%, controls: 18.5%). CNV gain was significantly associated with a greater risk of NAFLD (adjusted OR 2.22, 95% CI 1.42-3.46, P = 0.0004) and NASH (adjusted OR 2.33, 95% CI 1.47-3.68, P = 0.0003). Interestingly, subjects carrying extra copy number showed significantly higher serum ALT and triglyceride (P

    OBJECTIVES: This study aimed to gain an overview of patient education and the effects of patient education for older people with low back pain (LBP).

    METHODS: The search strategies were performed via EBSCO MEDLINE, EBSCO CINAHL, Science Direct, PubMed, and PEDro databases from 2006 to 2016. The keywords "patient education", "low back pain", "elderly", "older adults", "older persons" and "older people" were used during the literature search. Boolean operators were used to expand or limit the searching scope and manual exclusion was performed to choose articles eligible for this study.

    RESULTS: A total of 2799 articles were retrieved but only five articles were related with patient education for older people with LBP. Findings suggest that patient education for older people may differ in terms of its contents such as health education, self-management, video education, and postural education. The high methodological quality of the studies revealed that patient education showed improvement in terms of pain, disability and quality of life among older people with LBP.

    CONCLUSIONS: Patient education improved pain and had positive effects on disability and quality of life among older people with LBP. However, due to the limited number of RCTs more studies are needed to provide evidence for its effectiveness.

    BACKGROUND: Anemia is not only a major public health problem among children in developing countries, it is also an important predictor for their future growth and development. The objective of this study was to identify possible factors associated with anemia among pre-school children in Bangladesh after removing a cluster effect of the population, and to determine the prevalence of this condition.

    METHODS: Data for this study was extracted from the 2011 Bangladesh Demographic and Health Survey (BDHS-2011). In this survey, data was collected using a two-stage stratified cluster sampling approach. The chi-square test and a two-level logistic regression model were used for further analysis.

    RESULTS: Data from 2231 children aged 6-59 months were included for analysis. The prevalence of child anemia was noted to be 52.10%. Among these anemic children, 48.40% where from urban environment and 53.90% were from rural areas. The prevalence of mild, moderate and severe anemia among children was 57.10, 41.40 and 1.50% respectively. The two-level logistic regression model revealed that the following factors were associated with childhood anemia: children of anemic mothers (p

    INTRODUCTION: Obstructive sleep apnea patients may develop deficits in the cognitive domains of attention, concentration, executive function, verbal and visuospatial memory, constructional abilities, and psychomotor functioning. As cognitive performance will improve with the treatment, early screening for cognitive dysfunction should be done to prevent further deterioration.

    OBJECTIVE: We aim to evaluate the cognitive function of obstructive sleep apnea patients by using the 'Mini Mental State Examination'.

    METHODOLOGY: This was a cross sectional study to evaluate the cognitive function of moderate and severe obstructive sleep apnea patients with age ranged from 18 to 60 old who attended our sleep clinic. These patients were confirmed to have moderate and severe obstructive sleep apnea by Type 1 polysomnography (attended full overnight study). The age, gender and ethnicity were noted and other relevant data such as weight, height, body mass index and apnea and hypopnoea index were recorded accordingly. The cognitive function was evaluated using validated Malay version of Mini Mental State Examination which measured 5 areas of cognitive functions comprising orientation, registration, attention and calculation, word recall and language abilities, and visuospatial.

    RESULTS: A total of 38 patients participated in this study. All 19 patients of moderate group and 14 patients of severe group had normal cognitive function while only 5 patients in severe group had mild cognitive function impairment. There was a statistically significant difference between the moderate group and severe group on cognitive performance (p value = 0.042).

    CONCLUSIONS: Severe obstructive sleep apnea patients may have impaired cognitive function. Mini Mental State Examination is useful in the screening of cognitive function of obstructive sleep apnea patients but in normal score, more sophisticated test batteries are required as it is unable to identify in 'very minimal' or 'extremely severe' cognitive dysfunction.

    Obstructive sleep apnea (OSA) has been identified as one of the significant risk factors for motor vehicle crashes (MVCs). In the interest of public safety, this study was conducted to determine the prevalence of OSA and its associated factors among express bus drivers in Malaysia. Identifying factors or conditions related with OSA is very important because they can be used as indicators to subject a person to a confirmatory diagnosis using polysomnography testing.

    The benefits and safety of intravenous recombinant tissue plasminogen activator (IV-tPA) for patients with mild ischaemic stroke (MIS) are still unclear. The objective of this meta-analysis was to evaluate the efficacy and safety of IV-tPA as treatment for patients with MIS. We performed a systematic literature search across MEDLINE, Embase, Central, Global Health and Cumulative Index to Nursing and Allied Health Literature (CINAHL), from inception to 10 November 2016, to identify all related studies. Where possible, data were pooled for meta-analysis with odds ratio (OR) and corresponding 95% confidence interval (CI) using the fixed-effects model. MIS was defined as having National Institutes of Health Stroke Scale score of ≤6. We included seven studies with a total of 1591 patients based on the prespecified inclusion and exclusion criteria. The meta-analysis indicated a high odds of excellent functional outcome based on the modified Rankin Scale or Oxfordshire Handicap Score 0-1 (OR=1.43; 95% CI 1.14 to 1.79; P=0.002, I2=35%) in patients treated with IV-tPA compared with those not treated with IV-tPA (74.8% vs 67.6%). There was a high risk of symptomatic intracranial haemorrhage (sICH) with IV-tPA treatment (OR=10.13; 95% CI 1.93 to 53.02; P=0.006, I2=0%) (1.9% vs 0.0%) but not mortality (OR=0.78; 95% CI 0.43 to 1.43; P=0.43, I2=0%) (2.4% vs 2.9%). Treatment with IV-tPA was associated with better functional outcome but not mortality among patients with MIS, although there was an increased risk of sICH. Randomised trials are warranted to confirm these findings.
