Dyslexia with and without Irlen syndrome: A study of influence on abilities and brain-derived neurotrophic factor level.

The presence of comorbid Irlen syndrome (IS) in children with developmental dyslexia (DD) may have an impact on their reading and cognitive abilities. Furthermore, the brain-derived neurotrophic factor (BDNF) was reported to be expressed in brain areas involved in cognitive and visual processing. The aim of this study was to evaluate some cognitive abilities of a group of dyslexic children with IS and to measure and compare the plasma BDNF level to dyslexic children without IS and neurotypical (NT) children. The participants were 60 children with DD (30 in the DD + IS group; 30 in the DD group) and 30 NT children. The Irlen reading perceptual scale, the Stanford Binet intelligence scale, 4th ed, the dyslexia assessment test, and the Illinois test of psycholinguistic abilities were used. The BDNF level was measured using the enzyme-linked immunosorbent assay. One-minute writing and visual closure deficits were more prevalent, while phonemic segmentation deficits were less prevalent in the DD + IS group compared to the DD group. The BDNF level in the DD groups was lower than that in NT children (p < 0.001). Some reading and non-reading tasks were influenced by the presence of a coexisting IS. The reduced BDNF level could play a role in the deficits noticed in the abilities of children with DD.

Linkage to primary-care public health facilities for cardiovascular disease prevention: a community-based cohort study from urban slums in India.

OBJECTIVES: Hypertension and diabetes mellitus are important risk factors for cardiovascular diseases (CVDs). Once identified with these conditions, individuals need to be linked to primary healthcare system for initiation of lifestyle modifications, pharmacotherapy and maintenance of therapies to achieve optimal blood pressure and glycaemic control. In the current study, we evaluated predictors and barriers for non-linkage to primary-care public health facilities for CVD risk reduction. METHODS: We conducted a community-based longitudinal study in 16 urban slum clusters in central India. Community health workers (CHWs) in each urban slum cluster screened all adults, aged 30 years or more for hypertension and diabetes, and those positively screened were sought to be linked to urban primary health centres (UPHCs). We performed univariate and multivariate analysis to identify independent predictors for non-linkage to primary-care providers. We conducted in-depth assessment in 10% of all positively screened, to identify key barriers that potentially prevented linkages to primary-care facilities. RESULTS: Of 6174 individuals screened, 1451 (23.5%; 95% CI 22.5 to 24.6) were identified as high risk and required linkage to primary-care facilities. Out of these, 544 (37.5%) were linked to public primary-care facilities and 259 (17.8%) to private providers. Of the remaining, 506 (34.9%) did not get linked to any provider and 142 (9.8%) defaulted after initial linkages (treatment interrupters). On multivariate analysis, as compared with those linked to public primary-care facilities, those who were not linked had age less than 45 years (OR 2.2 (95% CI 1.3 to 3.5)), were in lowest wealth quintile (OR 1.8 (95% CI 1.1 to 2.9), resided beyond a kilometre from UPHC (OR 1.7 (95% CI 1.2 to 2.4) and were engaged late by CHWs (OR 2.6 (95% CI 1.8 to 3.7)). Despite having comparable knowledge level, denial about their risk status and lack of family support were key barriers in this group. CONCLUSIONS: This study demonstrates feasibility of CHW-based strategy in promoting linkages to primary-care facilities.

Stability of lip-print patterns: a longitudinal study of Saudi females.

Lip-print groove patterns have recently been verified as a unique parameter for identification. This study investigated the stability of lip-print patterns over time to validate their secure use in civil and criminal investigations. One hundred and sixteen female lip prints were analyzed and compared with the prints of the same subjects taken 3 years earlier. The old and new lower lip prints of each subject were examined for similarities in the groove patterns in different areas of the lip (lower right, lower middle and lower left), and a score for similarity was developed for the statistical analysis of the lower lip stability data. No significant difference in the frequency of pattern types was detected between old and new prints (P > 0.05). Statistically, 89.6% of subjects showed characteristic typical groove(s) in the lip area(s) of the old and corresponding new prints: 24.1% in the three areas, 48.3% in two areas and 17.2% in one area. This study proves the lasting stability of lip-print patterns over the years in Saudi females and recommends paying attention to the presence of characteristic typical grooves in these prints. Further studies on larger samples, including male prints, should be performed to validate the lip prints for criminal use.
