Epidemiology of malocclusion and orthodontic treatment need of 12-13-year-old Malaysian schoolchildren

Esa R, Razak IA, Allister JH

Community Dent Health, 2001 Mar;18(1):31-6.
PMID: 11421403

Data on malocclusion and orthodontic treatment need in Malaysia are limited. The purpose of this study was to evaluate malocclusion and orthodontic treatment need in a sample of 12-13-year-old schoolchildren using the Dental Aesthetic Index (DAI), and to assess the relationship between malocclusion and socio-demographic variables, perceptions of need for orthodontic treatment, aesthetic perception and social functioning.

Novel use of 3T MRI in assessment of optic nerve volume in glaucoma

Ramli NM, Sidek S, Rahman FA, Peyman M, Zahari M, Rahmat K, et al.

Graefes Arch Clin Exp Ophthalmol, 2014 Jun;252(6):995-1000.
PMID: 24770532 DOI: 10.1007/s00417-014-2622-6

PURPOSE: To measure optic nerve (ON) volume using 3 T magnetic resonance imaging (MRI), to correlate ON volume with retinal nerve fiber layer (RNFL) thickness, and to determine the viability of MRI as an objective tool in distinguishing glaucoma severity.
METHODS: In this cross-sectional study, 30 severe glaucoma patients, 30 mild glaucoma patients and 30 age-matched controls were recruited. All subjects underwent standard automated perimetry, RNFL analysis and 3 T MRI examinations. Glaucoma patients were classified according to the Hodapp-Anderson-Parish classification. Pearson's correlation coefficient was used to correlate ON volume with RNFL, and receiver operating curve (ROC) analysis was performed to determine the sensitivity and specificity of ON volume in detecting glaucoma severity.
RESULTS: Optic nerve volume was significantly lower in both the left and right eyes of the severe glaucoma group (168.70 ± 46.28 mm(3); 167.40 ± 45.36 mm(3)) than in the mild glaucoma group (264.03 ± 78.53 mm(3); 264.76 ± 78.88 mm(3)) and the control group (297.80 ± 71.45 mm(3); 296.56 ± 71.02 mm(3)). Moderate correlation was observed between: RNFL thickness and ON volume (r = 0.51, p <0.001), and in mean deviation of visual field and optic nerve volume (r = 0.60, p

On optimizing the blocking step of indirect enzyme-linked immunosorbent assay for Epstein-Barr virus serology

Lim CS, Krishnan G, Sam CK, Ng CC

Clin Chim Acta, 2013 Jan 16;415:158-61.
PMID: 23043757 DOI: 10.1016/j.cca.2012.08.031

Because blocking agent occupies most binding surface of a solid phase, its ability to prevent nonspecific binding determines the signal-to-noise ratio (SNR) and reliability of an enzyme-linked immunosorbent assay (ELISA).

Fulltext Home blood pressure control status in 2017-2018 for hypertension specialist centers in Asia: Results of the Asia BP@Home study

A self-measured home blood pressure (BP)-guided strategy is an effective practical approach to hypertension management. The Asia BP@Home study is the first designed to investigate current home BP control status in different Asian countries/regions using standardized home BP measurements taken with the same validated home BP monitoring device with data memory. We enrolled 1443 medicated hypertensive patients from 15 Asian specialist centers in 11 countries/regions between April 2017 and March 2018. BP was relatively well controlled in 68.2% of patients using a morning home systolic BP (SBP) cutoff of <135 mm Hg, and in 55.1% of patients using a clinic SBP cutoff of <140 mm Hg. When cutoff values were changed to the 2017 AHA/ACC threshold (SBP <130 mm Hg), 53.6% of patients were well controlled for morning home SBP. Using clinic 140 mm Hg and morning home 135 mm Hg SBP thresholds, the proportion of patients with well-controlled hypertension (46%) was higher than for uncontrolled sustained (22%), white-coat (23%), and masked uncontrolled (9%) hypertension, with significant country/regional differences. Home BP variability in Asian countries was high, and varied by country/region. In conclusion, the Asia BP@Home study demonstrated that home BP is relatively well controlled at hypertension specialist centers in Asia. However, almost half of patients remain uncontrolled for morning BP according to new guidelines, with significant country/regional differences. Strict home BP control should be beneficial in Asian populations. The findings of this study are important to facilitate development of health policies focused on reducing cardiovascular complications in Asia.
