ABSTRACT

Maintaining good oral hygiene is important following stroke. This study aimed to evaluate the effectiveness of two oral health promotion (OHP) programmes to reduce dental plaque levels following stroke. A multi-centre randomised clinical control trial was conducted among patients hospitalised following stroke in Malaysia. Patients were randomly allocated to two OHP groups: (i) control group who received the conventional method for plaque control-daily manual tooth brushing with a standardised commercial toothpaste, (ii) test group-who received an intense method for plaque control-daily powered tooth brushing with 1% Chlorhexidine gel. Oral health assessments were performed at baseline, at 3 months and 6 months post-intervention. Within- and between-group changes in dental plaque were assessed over time. Regression analyses were conducted on dental plaque levels at 6 months controlling for OHP group, medical, dental and socio-demographic status. The retention rate was 62.7% (54 of 86 subjects). Significant within-group changes of dental plaque levels were evident among the test group (P < .001) and the control group (P < .001). No significant between-group changes of dental plaque levels were apparent (P > .05). Regression analyses identified that baseline plaque levels (adjusted ß = 0.79, P < .001) and baseline functional dependency level (adjusted ß = -0.34, P < .05) were associated with dental plaques levels at the end of the trial (6 months). Both, "Conventional" and "Intense" oral health promotion programmes may successfully reduce dental plaque during stroke rehabilitation and are of comparable effectiveness. Baseline dental plaque levels and functional dependency level were key factors associated with dental plaque levels at follow-up at 6 months.

ABSTRACT

BACKGROUND AND PURPOSE: Both blood pressure (BP) and its variability (BPV) are established risk factors for development of atherosclerotic disease and are associated with an increased risk for cardiovascular and all-cause mortality. The prognostic implications of outpatient clinic visit-to-visit BPV amongst patients with lacunar infarction are nevertheless unknown. METHODS: The clinical outcome of 281 patients with lacunar infarction was prospectively followed up. The average BP and BPV, as determined by the standard deviation of the systolic and diastolic BP, were recorded during a mean 13 ± 6 outpatient clinic visits. RESULTS: The mean age of the population was 70 ± 10 years. After a mean 78 ± 18 months follow-up, 65 patients died (23%), 31% (20/65) due to cardiovascular causes; 14% and 7% developed recurrent stroke and acute coronary syndrome. After adjusting for age, sex, mean systolic and diastolic BP, cardiovascular risk factors and comorbidities, patients with a systolic BPV of the third tertile had significantly higher risk of all-cause mortality [hazard ratio (HR) 1.97, 95% confidence interval (CI) 1.02-3.80, P = 0.04) and cardiovascular mortality (HR 7.64, 95% CI 1.65-35.41, P < 0.01) than those with systolic BPV of the first tertile. Nevertheless, systolic BPV did not predict recurrent stroke or acute coronary syndrome. Diastolic BPV did not predict various adverse clinical outcomes. CONCLUSIONS: Visit-to-visit systolic BPV predicts long-term all-cause and cardiovascular mortality after lacunar infarct, independent of conventional risk factors including average BP control.

ABSTRACT

OBJECTIVES: To investigate the effects of garlic on endothelial function in patients with ischemic stroke (ISS). DESIGN: Cross-sectional study. PARTICIPANTS: 125 Chinese patients with prior ISS due to athero-thrombotic disease were recruited from the outpatient clinics during July 2005 to December 2006. MEASUREMENTS: Daily allium vegetable intake (including garlic, onions, Chinese chives and shallots) was ascertained by means of a validated food frequency questionnaire for Chinese and brachial artery flow-mediated dilatation (FMD) was measured using high-resolution ultrasound in all subjects. RESULTS: The mean age of the study population was 65.9±11.1 years and 69% were males. Mean allium vegetable intake and garlic intake of the study population was 7.5±12.7g/day and 2.9±8.8g/day respectively. Their mean FMD was 2.6±2.3%. Daily intake of total allium vegetable (r=0.36, P<0.01) and garlic (r=0.34, P<0.01) significantly correlated with FMD. Using the median daily allium intake as cut-off (3.37g/day), patients with a low allium intake <3.37g/day was noted to have a lower FMD compared to those with a normal allium intake (2.1±2.1% versus 3.0±2.4%, P<0.05). After adjusting for confounding factors, multi-variate analysis identified that daily allium vegetable (B=0.05, 95% confidence interval: 0.02, 0.09, P<0.01) and garlic (B=0.07, 95% confidence interval: 0.02, 0.12, P<0.01) intake, but not onions, Chinese chives and shallots were independent predictors for changes in FMD in patients with ISS. CONCLUSIONS: Daily garlic intake is an independent predictor of endothelial function in patients with ISS and may play a role in the secondary prevention of atherosclerotic events.

ABSTRACT

OBJECTIVES: To describe the changes in bone density and geometry of the radius after chronic stroke and the associated clinical factors. METHODS: Twenty stroke patients (12 men and 8 women, age=42-78 years, time post-stroke=12-166 months) and 23 control participants (14 men and 9 women, age=53-77 years) were assessed at the time of enrolment and one year later. Peripheral quantitative computed tomography was used to scan the radius epiphysis (4% site) and diaphysis (33% site). Grip strength, spasticity, paretic arm disuse, physical activity, and vascular health were also evaluated. RESULTS: During the follow-up period, only the cortical thickness and cortical bone mineral content (BMC) in the paretic radius diaphysis showed a decline that exceeded the least significant change value (p=0.002). Paretic arm disuse, lower vascular elasticity and physical activity level at initial assessment were significantly related to more decline in cortical thickness at this site (p<0.01). CONCLUSIONS: The paretic radius diaphysis sustained significant reduction in cortical thickness and cortical BMC over time in chronic stroke, but these changes were less pronounced than those previously reported in sub-acute stroke. Strategies to modify vascular health, disuse, and physical activity may be important in improving upper limb bone health but will need further investigations.

ABSTRACT

The oral cavity serves as a reservoir of Staphylococcus aureus for infection of the lower respiratory tract and cross-infection to other patients. This systematic review was designed to examine the effectiveness of oral health promotion interventions on this pathogen. The PubMed, ISI Web of Science, and Cochrane Library databases were searched for clinical trials assessing the effect of oral health promotion interventions on oral and oropharyngeal carriage of S. aureus. Oral health promotion interventions on oral reservoirs of S. aureus in both systemically healthy and medically compromised groups consisted of oral hygiene interventions only. There was a lack of evidence pertaining to the effectiveness of mechanical oral hygiene interventions against this pathogen. Chlorhexidine delivered in oral hygiene products such as mouthrinses, gels, and sprays appeared to have some utility against S. aureus, although some studies found equivocal effects. There was a dearth of studies investigating the efficacy of other chemical agents. Although many chemical agents contained in oral hygiene products have proven in vitro activity against S. aureus, their clinical effectiveness and potential role as adjuncts or alternative therapies to conventional treatment remain to be confirmed by further high-quality randomized controlled trials.

ABSTRACT

OBJECTIVE: Adipocyte fatty acid-binding protein (A-FABP) is an adipokine shown to have adverse metabolic and proinflammatory effects, and contributes to atherosclerosis in mice. However, its role in cardiovascular diseases in humans remains to be established. In this case-control study, we investigated the association of serum A-FABP with ischemic stroke, and examined its association with early mortality. METHODS: Serum A-FABP was measured, using ELISA, in 306 subjects with acute ischemic stroke and 306 age-, sex-, and body mass index-matched controls. All controls were free of cardiovascular diseases. Serum A-FABP was also measured in another 60 ischemic stroke subjects who died within 3 months of acute stroke. RESULTS: Serum A-FABP was higher in subjects with ischemic stroke as compared to controls (19.6 ng/mL [14.3-28.4 ng/mL] vs 15.2 ng/mL [10.6-23.6 ng/mL] in men and 32.4 ng/mL [24.5-45.7 ng/mL] vs 22.0 ng/mL [14.3-34.0 ng/mL] in women, stroke vs control, p<0.001). On logistic regression analyses with the model including hypertension, diabetes, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride, lipid-lowering treatment, smoking, and A-FABP, serum A-FABP was independently associated with stroke (odds ratio 2.10, 95% confidence interval 1.50-2.94, p<0.001), and the associations of A-FABP with ischemic stroke were additive to conventional risk factors, as demonstrated on likelihood ratio tests (p<0.001). Furthermore, high serum A-FABP was associated with increased 3-month mortality in ischemic stroke subjects (odds ratio 2.65, 95% confidence interval 1.18-5.96, p=0.018), independent of age and NIH Stroke Scale score. CONCLUSIONS: Serum A-FABP was significantly associated with ischemic stroke in our case-control study, and may serve as a useful prognostic indicator for early mortality.

ABSTRACT

This study aimed to assess agreement between patient and proxy assessment of patients' oral health-related quality of life (OHRQoL) during the acute stroke phase and 6 months after hospital discharge. As part of an observational longitudinal study, 161 consecutive patients hospitalized after stroke and their caregivers (CGs) were monitored during acute stroke and 6 months after hospital discharge. Patient-CG agreement of health-related quality of life as assessed by the General Oral Health Assessment Index (GOHAI) and Medical Outcomes Study 12-item Short Form (SF-12) which comprises physical (PCS-12) and mental component summaries (MCS-12) was determined by comparison and correlation analyses. Complete data were available for 65 patients and CGs. Compared with acute stroke, there were improvements in GOHAI and SF-12 scores from patient's and CG's perspective at 6-month follow-up. Caregivers overestimated the impact of stroke on MCS-12 over a period of time (P < 0.01) and underestimated the impact on GOHAI during acute stroke (P < 0.001) and on PCS-12 6 months later (P < 0.05). Patient-CG agreement was substantial to excellent during acute stroke [intra-class correlation coefficient (ICC 0.69-0.86)] and fair-to-moderate 6 months later (ICC 0.28-0.60). Agreement was adequate between patients' and CGs' assessment of patient OHRQoL during acute stroke but it was less reliable 6 months after hospital discharge. These findings suggest that proxy assessment of OHRQoL after stroke is effective in assessing stroke-related oral impairments that affect life quality without placing additional burden on stroke patients themselves to assess OHRQoL.

ABSTRACT

BACKGROUND: Patients with major depressive disorder are found to show selective attention biases towards mood-congruent information. Although previous studies have identified various structural changes in the brains of these patients, it remains unclear whether the structural abnormalities are associated with these attention biases. In this study, we used voxel-based morphometry (VBM) to explore the structural correlates of attention biases towards depression-related stimuli. METHOD: Seventeen female patients with major depressive disorder and 17 female healthy controls, matched on age and intelligence, underwent magnetic resonance imaging (MRI). They also performed positive-priming (PP) and negative-priming (NP) tasks involving neutral and negative words that assessed selective attention biases. The reaction time (RT) to a target word that had been attended to or ignored in a preceding trial was measured on the PP and NP tasks respectively. The structural differences between the two groups were correlated with the indexes of attention biases towards the negative words. RESULTS: The enhanced facilitation of attention to stimuli in the PP task by the negative valence was only found in the depressed patients, not in the healthy controls. Such attention biases towards negative stimuli were found to be associated with reduced gray-matter concentration (GMC) in the right superior frontal gyrus, the right anterior cingulate gyrus and the right fusiform gyrus. No differential effect in inhibition of attention towards negative stimuli in the NP task was found between the depressed patients and the healthy controls. CONCLUSIONS: Specific structural abnormalities in depression are associated with their attention biases towards mood-congruent information.

ABSTRACT

AIM: To investigate prospectively the qualitative and quantitative changes in oral carriage of yeasts and coliforms in southern Chinese people suffering from stroke. MATERIALS AND METHODS: In 56 elderly people suffering from stroke in a rehabilitation unit of a general medical hospital in Hong Kong, oral microbiological sampling using a combined imprint culture, oral rinse approach and clinical assessment was made during the acute stroke phase, on hospital discharge and 6 months later. RESULTS: The oral carriage of yeasts increased significantly during acute stroke (P<0.05), whereas coliform carriage did not. A reduction in oral carriage of yeasts was found on hospital discharge and 6 months later and in coliforms at the 6-month assessment (P<0.05). Candida albicans and Klebsiella pneumoniae were the predominant yeast and coliform respectively. Stroke-related difficulty in tooth brushing and denture wearing were associated with higher oral yeast carriage (P<0.05). We also report here for the first time that the use of aspirin was associated with lower oral yeast carriage in people suffering from stroke. CONCLUSION: Oral yeast carriage was closely linked to the level of stroke-related functional disability that improved over time but had not totally resolved 6 months after hospital discharge. The oral reservoir of yeasts and coliforms in people suffering from stroke is noteworthy by care providers as K. pneumoniae may cause aspiration pneumonia.

ABSTRACT

OBJECTIVES: To assess the agreement between patients' and caregivers' (CGs) assessment of patients' oral health-related quality of life (OHRQoL) during the acute stage of their hospitalization. METHODS: A sample of 161 consecutive patients admitted to hospital following stroke and their CGs. Patients and CGs were interviewed independently about the impact of oral health status on the life quality of the patient employing the General Oral Health Assessment Index (GOHAI). Agreement of impact was assessed by comparison (agreement at the group level) and correlation analyses (agreement of individual patient-CG pairs). RESULTS: The response rate was 76% with 121 pairs of patients and CGs participating. At the group level, variations in patient's own and CG GOHAI scores were found (P < 0.001). The CGs underestimated the impact of oral health on life quality, particularly with respect to aspects of psychosocial functioning compared with patients' own perceptions. However, the bias in reports was small (standardized difference = 0.43). The mean absolute difference in overall scores constituted 8% of the possible range of GOHAI scores. At the individual patient-CG pair level, the intraclass correlation coefficient for GOHAI scores was 0.73 (95% CI 0.61-0.82), indicating substantial agreement. CONCLUSION: At the group and individual level there was adequate agreement between patients' and CGs' assessment of patients' OHRQoL during the acute stage of their hospitalization. The findings have implications in the use of CGs as proxies in assessing oral health when patients' own assessment may be difficult to obtain.

ABSTRACT

The study aimed to investigate oral health-related quality of life (OHR-QoL) of stroke survivors on hospital discharge after rehabilitation. It was a cross-sectional study involving 43 elderly survivors of mild to moderate stroke about to be discharged from hospital after rehabilitation and a comparison group of 43 community-dwelling elderly people. The Medical Outcomes Short Form 36 (SF-36) measure, the General Oral Health Assessment Index (GOHAI) and an oral health transition scale were administered prior to a dental examination. Median SF-36 subscale scores were significantly different between groups (P < 0.05). In physical function, role-physical, role-emotional and mental health domains, stroke survivors had significantly lower scores indicating poorer health. The median GOHAI score for the stroke group was 52 and 54 for the comparison group with no significant difference between groups although more stroke survivors had difficulty speaking compared with the comparison group. About 75% of stroke survivors considered their appearance to be worse, half of them felt that speech was worse and about a third had difficulty chewing hard food compared with the pre-stroke condition (P < 0.05). Most participants were partially dentate with no significant difference in DMFT scores or prosthetic status between groups (P > 0.05). Health-related quality of life in general was significantly poorer after stroke although patients were considered physically well enough to be discharged from hospital. There was some impairment of OHR-QoL. The nature of the stroke, the hospital environment including diet, coping strategies and elderly Chinese peoples' perception of health should be taken into account when interpreting measures of health status in stroke survivors.

ABSTRACT

PRIMARY OBJECTIVE: brain injury can result in the loss of previous learnt behaviours that affect an individual's daily functioning. The use of self-regulation helps the individual to relearn the lost behaviours by bringing him/her to self-conscious level through independent and reflective learning derived using a social cognitive perspective. The purpose of this paper is to report on clinical observations made with the use of self-regulation in people with brain injury during the relearning of lost functions. METHODS AND PROCEDURES: daily tasks were used to assess the relearning ability of the subjects pre- and post-programme. EXPERIMENTAL INTERVENTION: one-week self-regulatory training on five selected daily tasks. MAIN OUTCOMES AND RESULTS: these provisory observations would suggest that, with specific guidance for people with different needs, such as with impaired cognitive function and depression, self-regulation is effective in enhancing their relearning. CONCLUSION: Self-regulatory training is effective in enhancing the relearning of lost functions.

ABSTRACT

Oral perception and oral motor ability were assessed in edentulous patients with stroke, Parkinson's disease, and an age and gender matched control group. Standard stereognosis and oral motor ability tests were performed, with and without complete dentures in situ. Statistical comparisons were made using ANOVA, Levene's test and paired t-tests. Stroke patients had significantly poorer stereognostic measures than Parkinson's disease patients and controls (P < 0.02). Stereognostic measures were better in all groups when dentures were worn. There were no differences in oral motor ability between groups. Oral stereognosis was significantly impaired in stroke patients. Oral stereognostic ability was better in all groups when dentures were worn. The oral motor ability test lacked the sensitivity to detect differences in motor ability between experimental groups. Edentulous patients with stroke should be encouraged to wear dentures during the rehabilitation phase as oral stereognosis is then less impaired.

ABSTRACT

OBJECTIVE: To study the epidemiology of multiple sclerosis in Hong Kong Chinese. DESIGN: Cross-sectional questionnaire survey. SETTING: Neurology and paediatric neurology departments in Hong Kong from January through June 1999. PARTICIPANTS: All confirmed multiple sclerosis patients. MAIN OUTCOME MEASURES: Demographic data, investigation results, Kurtzke's Expanded Disability Status Scale during the last follow-up visit, number of relapses between 1997 and 1998, and treatments used/currently in use. RESULTS: Fifty-three Chinese multiple sclerosis patients were identified. The prevalence was thus estimated to be 0.77 per 100,000 population. This low prevalence was also noted in other multiple sclerosis studies from South-East Asia (range, 0.8-4 per 100,000 population). The female to male ratio among the Chinese multiple sclerosis sufferers was 9.6:1, a figure somewhat higher than that reported in the other studies from South-East Asia (range, 3.2-6.6:1). The Chinese multiple sclerosis patients in this study also had a high spinal cord involvement (66%) and a low presence of cerebrospinal fluid oligoclonal banding (40%). These findings were different from those in Caucasian multiple sclerosis patients. CONCLUSION: Multiple sclerosis in Hong Kong Chinese has a low prevalence, a high female to male ratio, and a low cerebrospinal fluid oligoclonal banding presence.
