Preschool Children Feeding Patterns And Early Childhood Oral Health Impact In Tanah Merah, Kelantan, Malaysia

@#Introduction: Poor feeding patterns increase risk of Early Childhood Caries (ECC), which can cause negative impacts on oral health-related quality of life (OHQoL) of preschool children and parents. This study aims to assess feeding patterns of preschool children and OHQoL of the children and their parents in Tanah Merah. Methods: A cross-sectional study was conducted involving 134 preschool children aged 5-6 years old from eight private preschools, chosen by multi-staged stratified cluster sampling. Parents answered adopted self-administered questionnaire on feeding patterns and oral health-related impacts. Mann-Whitney U test and Kruskal-Wallis test were used to compare the median between groups of feeding patterns. Results: A total of 122 parents responded. Majority of the children had history of bottle-feeding (97.5%) and being given solid food during infancy (61.2%). Many children were still using bottle to drink (38.5%). Majority were still given formula milk at least three times daily (51.1%) and were feed with bottle to put to sleep (97.9%). The Child Impact Section (CIS), Family Impact Section (FIS) and Overall ECOHIS mean scores were 2.39 (SD=3.41), 0.71 (SD=1.45) and 3.10 (SD=4.41), respectively. Most common impact reported in CIS was ‘oral pain’ (26.2%) whereas in FIS, ‘parents felt guilty’ (7.4%). None of feeding patterns were found significantly different in terms of ECOHIS score median (p-value>0.05). Children OHQoL reporting by proxy should be treated as complementary. Conclusion: Many preschool children were involved in prolonged, frequent and nocturnal bottle-feeding. No significant difference in median ECOHIS scores found according to feeding patterns.

Mediating Role of Job Satisfaction in the Relationship between Job Performance and Organizational Commitment Components: A Study among Nurses at One Public University Hospital in Malaysia

@#Introduction: In light of the importance of the nurses’ performance in health services, this study was established to examine the relationship of job performance with organizational commitment components and job satisfaction among nurses. It is also, to examine the mediating effect of job satisfaction in the relationship between organizational commitment components and job performance among nurses. Methods: This was a cross-sectional study conducted among nurses at Hospital Universiti Sains Malaysia. A sample size of 192 staff was selected using stratified and systematic random sampling methods. The study data were collected using a questionnaire consists of three scales: the organizational commitment scale of Allen and Meyer, the job satisfaction scale of Van Wood, and the task performance scale of Williams and Anderson. Besides, respondents were asked about their demographic profiles. The response rate was 92% (n= 176). Regression analysis according to Baron and Kenny technique and Pearson correlation were conducted to get the study results. Results: The study results showed that all organizational commitment components positively and significantly correlated with job satisfaction and job performance. Further, there is a positive relationship was found between job satisfaction and job performance. Moreover, findings of regression analysis showed that job satisfaction partially mediates the relationship between all organizational commitment components and job performance. Conclusion: Improving organizational commitment and job satisfaction among nurses could increase their performance. Nurses’ managers should create suitable approaches and strategies to promote the organizational commitment and job satisfaction of nurses to the highest level, which in turn enhancing their job performance and the quality of care.

Preliminary Result of Randomised Controlled Trial of Three Different Coated Archwires Part 1: Tooth Alignment and Coating Loss

@#Introduction: Coated archwires improve aesthetics during orthodontic treatment. However, little is known regarding their clinical benefit. This randomised controlled trial (RCT) compared the tooth alignment (TA), coating loss (CL), colour change (∆E*), and patient perception of coated archwires with their controls. Details of ∆E* and perception were reported in the second part of the articles. Methods: This RCT was done at three centres. Participants were randomised to receive one of four treatment interventions using 0.014” superelastic coated nickel-titanium archwires from Orthocare, RMO, G&H, and conventional uncoated 3M Unitek® archwires. These archwires were ligated during bonding and collected after eighth week and questionnaires were distributed to participants in the experimental groups only. After removal, TA and CL were measured using Little’s Irregularity Index and Autodesk® AutoCAD® software, respectively. At the time of this preliminary reporting, 84 participants had completed the trial. Two archwires fractured and were excluded. Therefore, 166 archwires (n = 166) were analysed. Results: Only non-extraction cases showed statistically significant differences in TA change between all groups (p = 0.005) and RMO showed significantly lowest mean of TA (1.5 mm). RMO and Orthocare showed significant TA change in the upper and lower arches (p = 0.037, 0.048). CL was found to be insignificant for both extraction and non-extraction cases (p >0.05). Comparison between upper and lower arches revealed no significant difference in TA and CL in all groups (p >0.05). Conclusion: From this preliminary analysis, Orthocare provides better TA in non-extraction cases despite highest percentage of coating loss.

Serological and Molecular Detection of Toxoplasmosis among Blood Donors in Tertiary Hospital of Malaysia

@#Introduction: This preliminary cross-sectional study aimed to investigate the prevalence of toxoplasmosis among blood donors in Kelantan, Malaysia. Methods: A total of 56 blood donors were screened by an enzyme-linked immunosorbent assay (ELISA) for anti-T. gondii Immunoglobulin G (IgG) and Immunoglobulin M (IgM) antibodies. Positive T. gondii IgG and IgM were further tested for IgG avidity ELISA. All extracted deoxyribonucleic acids (DNAs) from whole blood samples were analyzed for the presence of the Toxoplasma B1 gene and the ITS1 region by polymerase chain reaction (PCR). The socio-demographic data of donors was assessed using a data collection form. Results: Out of 56 blood donors, 24 (42.86%) donors were IgG+/IgM-, and 2 (3.57%) donors were IgG+/IgM+ with one of them having a high avidity index indicating as past infection for more than 20 weeks and the other with a low avidity index indicating as recent infection within 20 weeks. None of the samples tested positive for the presence of the Toxoplasma B1 gene and the ITS1 region. A univariate analysis showed that only employment status was significantly associated with Toxoplasma seropositivity. Conclusion: The seroprevalence of toxoplasmosis among blood donors in Kelantan, Malaysia, was 46.43%. Nevertheless, direct detection by PCR showed that this parasite was absent in the blood. These results highlight that the blood donors in this study had previously been exposed to T. gondii infection. The parasite may still remain in certain tissues but does not freely circulate in the blood.

Preliminary Result of Randomised Controlled Trial of Three Different Coated Archwires Part 2: Colour Change and Patient Perception

@#Introduction: Coated archwires improve aesthetics because of the tooth-coloured appearance. However, colour change of the coated archwires have been reported in vitro. Nonetheless, little is known to what extent this colour change occurs clinically. This second part of the multi-centre, double-blind, randomised controlled trial evaluated the colour change (∆E*) of three coated archwires with their controls and patient perception. Methods: 84 patients who received treatment with upper and lower fixed appliance treatment were invited. Consented patients were randomised to receive one of four treatment interventions using 0.014” superelastic nickel-titanium archwires from (1) Orthocare (2) RMO (3) G&H, and (4) 3M Unitek® uncoated. These archwires were ligated during bonding and collected after 8th week. After removal, the digital images of the archwires were assessed for colour change using Adobe® Photoshop® software, and the CIE L*a*b* system was used to calculate the ΔE* values. Patient perception was measured using oral aesthetic subjective impact scale (OASIS) questionnaire. Results: For colour change and patient perception assessment, 132 archwires from 66 participants who had been treated with aesthetic archwires were collected. Two fractured archwires were excluded. Initial analysis revealed all three aesthetic archwires groups showed significant mean of ∆E* with the highest was found in Orthocare (23.9), and the lowest is G&H (16.8). Post hoc comparison revealed statistically significant mean of ∆E* in Orthocare when compared with other groups (p <0.001). There was no statistically significant difference for patient perception between archwire groups. Conclusion: Preliminary results revealed that significant ∆E* in Orthocare group and patients showed positive perception following clinical use
