OBJECTIVE: To assess the influence of gender, academic level, and the presence of painful symptoms on the perception of risk factors at work contributing to musculoskeletal symptoms among dental students of Melaka, Malaysia.
METHODS: A cross-sectional survey of 183 clinical year dental students based on a convenience sample. The data were collected using the Nordic Musculoskeletal Questionnaire and Job Factor Questionnaire for assessment of musculoskeletal symptoms and risk factors at work respectively. Study data were evaluated using percentage, median, Cochran's Q test, Bonferroni correction, multiple linear regression analysis and Mann-Whitney U Test. The analysis was interpreted considering a 95 % confidence interval and significant level at P
METHODS: A comparative cross-sectional study was conducted among children with T1DM and healthy children aged 7 to 17 years old in Hospital Universiti Sains Malaysia from 2017 to 2019. Children with retinal disease or glaucoma were excluded. Macular and RNFL thicknesses were measured using spectral-domain optical coherence tomography. Demographic information, duration of diabetes, blood pressure, body mass index, visual acuity, and retinal examination findings were documented. Glycosylated hemoglobin levels, renal function, and blood lipid levels were also collected.
RESULTS: Forty-one children with T1DM and 80 age- and sex-matched children were enrolled. Both sexes were affected. Mean duration of diabetes mellitus was 3.66 years. The mean glycated hemoglobin levels in the T1DM group was 9.99%. The mean macular and RNFL thicknesses in children with T1DM were 277.56 (15.82) µm and 98.85 (12.05) µm, respectively. Children with T1DM had a significantly thinner average macula, superior outer macula, nasal outer macula, mean RNFL, and inferior RNFL thickness compared to controls (p < 0.05). There was a significant association between nephropathy and the mean RNFL thickness.
CONCLUSIONS: Children with T1DM had significantly decreased mean macular and RNFL thicknesses. Nephropathy is associated with an increased RNFL thickness.
RESEARCH DESIGN /SETTING: A cross-sectional validation study was conducted in middle and south of West Bank from February 2019 to June 2020. Two-hundred postpartum women were given self-administered and online questionnaire. Content and face validity were assessed. The "satisfaction of care" and "perceived quality of care" domains were analyzed using exploratory factor analysis, while items in "experience of mistreatment" domain were evaluated descriptively. Cronbach's alpha was used to assess the reliability of the questionnaire items.
FINDINGS: The new questionnaire consisted of three domains: "satisfaction of care", "perceived quality of care", and "experience of mistreatment" during childbirth. Five new items were added and two items were removed during content validation. Another two items were deleted through face validation. Exploratory factor analysis was conducted for the "satisfaction of care" and "perceived quality of care" domains. Two factors were identified for each domain, with a factor loading of more than 0.5. Twelve items were deleted from "satisfaction of care" domain and two items from "perceived quality of care" domain. The Cronbach's alpha values for the two factors in both domains were more than 0.87. The items in the "experience of mistreatment during childbirth" domain were evaluated descriptively.
KEY CONCLUSIONS: The new questionnaire is valid and reliable. The final questionnaire consists of 11 items for "satisfaction of care", 16 items for "perceived quality of care" and 43 items for "experience of mistreatment of women during childbirth".
