METHODS: A multicenter randomized clinical trial was conducted on hospitalized stroke survivors. Those in the control group were given standard care of oral hygiene (a manual toothbrush and toothpaste), whereas those in the test group were given intense care of oral hygiene (a powered toothbrush and 1% chlorhexidine oral gel). Oral clinical assessments were carried out, and microbiological samples were collected, using concentrated oral rinse samples at 3 time points: baseline, 3 months, and 6 months.
RESULTS: The prevalence of oral yeast was significantly reduced in the test group at 6 months (P < .05), but no significant difference was observed over time. A significant reduction was observed in the prevalence of Staphylococcus aureus (P < .01) and aerobic and facultative gram-negative bacilli over time (P < .05), but there were no significant differences noted between groups at 6 months. Candida albicans and Klebsiella pneumoniae were the prominent pathogens determined throughout the trial. Kluyvera strains have also been isolated from this cohort.
CONCLUSION: Oral hygiene intervention using a powered tooth brush and 1% chlorhexidine oral gel was effective in reducing the prevalence of oral opportunistic pathogens.
MATERIALS AND METHODS: A large scale survey of 13 centers in Malaysia was conducted involving 806 nurses in relation to oral hygiene care intentions and practices. In addition, information on personal and environmental factors was collected.
RESULTS: The response rate was 95.6% (778/806). The domains of the Theory of Planned Behavior were significantly associated with general intention to perform oral hygiene care: attitudes (β = 0.21, p
BACKGROUND: Oral hygiene care following stroke is important as the mouth can act as a reservoir for opportunistic infections that can lead to aspirational pneumonia.
DESIGN: A national cross-sectional survey was conducted in Malaysia among public hospitals where specialist stroke rehabilitation care is provided.
METHODS: All (16) hospitals were invited to participate, and site visits were conducted. A standardised questionnaire was employed to determine nurses' oral health knowledge for stroke care and existing clinical practices for oral hygiene care. Variations in oral health knowledge and clinical practices for oral hygiene care were examined.
RESULTS: Questionnaires were completed by 806 nurses across 13 hospitals. Oral health knowledge scores varied among the nurses; their mean score was 3.7 (SD 1.1) out of a possible 5.0. Approximately two-thirds (63.6%, n = 513) reported that some form of "mouth cleaning" was performed for stroke patients routinely. However, only a third (38.3%, n = 309) reported to perform or assist with the clinical practice of oral hygiene care daily. Their oral health knowledge of stroke care was associated with clinical practices for oral hygiene care (p
METHODS: The study adopted a qualitative approach to explore the opinions of secondary school students on the SDS implementation in their schools. Data from focus group discussions involving Form Two (14-year-olds) and Form Four (16-year-olds) students from the selected schools were transcribed verbatim and coded using the NVivo software before framework method analysis was conducted.
RESULTS: Among the strengths of the SDS were the convenience for students to undergo annual oral examination and dental treatment without having to visit dental clinics outside the school. The SDS also reduced possible financial burdens resulting from dental treatment costs, especially among students from low-income families. Furthermore, SDS helped to improve oral health awareness. However, the oral health education provided by the SDS personnel was deemed infrequent while the content and method of delivery were perceived to be less interesting. The poor attitude of the SDS personnel was also reported by the students.
CONCLUSION: The SDS provides effective and affordable dental care to secondary school students. However, the oral health promotion and education activities need to be improved to keep up with the evolving needs of the target audience.
MATERIALS AND METHODS: A total of 84 patients with treatment-naïve invasive breast cancer were enrolled into this retrospective study. The tumour stroma ratio (TSR) was estimated from the amount of tumour stroma in the pathology specimen of the breast tumour. The MRI images of the patients were analysed based on Breast Imaging Reporting and Data Systems (ACR-BIRADS) for qualitative features which include T2- weighted, diffusion-weighted images (DWI) and dynamic contrast-enhanced (DCE) for kinetic features. The mean signal intensity (SI) of Short Tau Inversion Recovery (STIR), with the ratio of STIR of the lesion and pectoralis muscle (L/M ratio) and apparent diffusion coefficient (ADC) value, were measured for the quantitative features. Correlation tests were performed to assess the relationship between TSR and MRI features.
RESULTS: There was a significant correlation between the margin of mass, enhancement pattern, and STIR signal intensity of breast cancer and TSR. There were 54.76% (n = 46) in the low stromal group and 45.24% (n = 38) in the high stromal group. A significant association were seen between the margin of the mass and TSR (p = 0.034) between the L/M ratio (p <0.001), and between STIR SI of the lesion and TSR (p<0.001). The median L/M ratio was significantly higher in the high TSR group as compared to the lower TSR group (p < 0.001).
CONCLUSION: Breast cancer with high stroma had spiculated margins, lower STIR signal intensity, and a heterogeneous pattern of enhancement. Hence, in this preliminary study, certain MRI features showed a potential to predict TSR.
