The effect of test kit provision, and individual and family education on the uptake rates of fecal occult blood test in an Asian population: a randomized controlled trial.

PURPOSE: The purpose of the study was to investigate whether fecal occult blood test (FOBT) home-delivery and individual education or combined with family education increases FOBT uptake rates in Singapore. METHODS: This is a randomized controlled intervention study of Singaporean residents aged 50 years and above, conducted in May 2012 till May 2013. Eligible individuals in randomly selected households were screened, and one member was randomly selected and allocated to one of the four arms: Group A (individual and family education, FOBT kits provided), Group B (individual education only, FOBT kits provided), Group C (no education, FOBT kits provided) and Group D (no education or FOBT kits provided). RESULTS: Overall response rate was 74.7 %. The FOBT return rates for groups A, B, C and D were 24.5 % [CI 16.2-34.4 %], 25.3 % [CI 16.4-36.0 %], 10.7 % [CI 4.7-19.9 %] and 2.2 % [CI 0.3-7.7 %], respectively. Respondents who were provided education and home-delivered FOBT kits were 15 times more likely to return FOBT kits [Group A: OR 15.0 (3.4-66.2); Group B: OR 15.5 (3.5-68.8)] and those provided with home-delivered FOBT without education were five times more likely to return FOBT kits [Group C: OR 5.8 (1.2-28.3)] than those without education and FOBT kits (Group D). There was no significant difference in return of FOBT kits whether education was provided to subject with or without a family member. CONCLUSION: Home delivery of FOBT kits increased FOBT return rates and individual education combined with home-delivered FOBT increased FOBT return rates even further. However, additional combination with family education did not increase FOBT rates further.

Evaluation of depression risk in LGI1 mutation carriers.

PURPOSE: Depression is the most common comorbid condition in epilepsy. The cause of this comorbidity is unknown, and could involve psychosocial consequences of epilepsy, treatment side effects, seizure manifestations, or common neurobiologic mechanisms. One hypothesis of particular interest is a shared genetic susceptibility to epilepsy and depression. We tested this hypothesis by studying depressive symptoms in families with an identified genetic form of epilepsy: autosomal dominant partial epilepsy with auditory features caused by mutations in the leucine-rich, glioma inactivated 1 gene (LGI1). METHODS: A standardized depression screen was administered to 94 individuals from 11 families with mutations in LGI1, including 38 mutation carriers with epilepsy (AC), 11 clinically unaffected mutation carriers (UC), and 45 noncarriers (NC). RESULTS: Current depressive symptom scores were significantly higher in AC than in NC, an association that remained after excluding depressive symptoms that appeared likely to be caused by antiepileptic medication use. However, scores did not differ between UC and NC. DISCUSSION: Although LGI1 mutation carriers who were clinically affected with epilepsy had increased depressive symptoms, mutation carriers without epilepsy did not. These findings suggest that the increase in depressive symptoms in affected individuals from these families is related to epilepsy or its treatment rather than to LGI1 mutations per se.
