PURPOSE To quantify eye lens dose in interventional radiology and assess whether neck dosimeter is a good surrogate to evaluate eye lens dosimetry. METHODS Radiation exposure was prospectively measured in 9 interventional radiologists between May and October 2017. Standard Hp(0,07) thermoluminescent dosimeters (TLDs) were worn at the neck outside the lead apron, and 2 dedicated eye lens Hp(3) TLDs were placed just above the eyes, one midline and another at the outer edge of the left eye. Correlations between eye lens and neck TLD doses were assessed with Pearson coefficient, and linear regression was used to predict eye lens dose from neck TLD values. RESULTS Eye lens dose without eye protection was 0.18 ± 0.11 (mean ± standard deviation; 0.08-0.41) mSv per workday and 35.3 ± 6.6 mSv (16.3-82.9) annually (200 workdays/year). Five (56%) radiologists exceeded the 20 mSv annual eye lens dose limit. Eye lens doses from left and central TLDs were 12.46 ± 3.02 and 9.29 ± 3.38 mSv, respectively (P = .027). Mean eye lens (left and central) and neck TLD doses were 10.87 ± 2.67 and 16.56 ± 5.67 mSv, respectively (P = .008). Pearson correlation coefficient between both eye lens TLD and between mean eye lens TLD and neck TLD doses were 0.91 and 0.92, respectively. Average of eye lens dose was 0.0179 + (0.5971 × neck dose). CONCLUSION Full-time interventional radiologists are likely to suffer from deterministic radiation effects to the eye lens, especially on the left side. Neck TLD significantly overestimates eye lens dose. However, eye lens doses are highly correlated with neck doses and may be predicted from the neck TLD values.Background Temporary alcohol abstinence conveys physiological benefits. Less well-known are its effects on well-being and general self-efficacy (GSE), and how use of support during alcohol abstinence challenges affects success rates.Methods In this study, 4232 adults participating in 'Dry January' completed a baseline questionnaire and a 1-month follow-up questionnaire. Key follow-up variables related to whether respondents completed the abstinence challenge, their use of support provided by Dry January, and changes in well-being and GSE. Analyses also examined whether well-being and GSE explained variance in the likelihood of completing Dry January not accounted for by other variables known to be associated with successful attempts at Dry January.Results Participation in Dry January was associated with increases in well-being and GSE among all respondents these changes were larger among people who successfully completed the challenge. In multivariate analysis, greater use of email support was a significant independent correlate of completing Dry January.Conclusions This paper adds to growing evidence that support provided through organised abstinence challenges is associated with changes in beliefs linked to harmful drinking. However, there is a need for further research to help us to understand what forms of support are most effective for different drinkers.Background Students with visual loss may benefit from assistive technology (AT) for their educational activities.Aim To understand the barriers faced in using ATs by students who have heard of ATs and reported needing them, but were not using (acquainted students), at schools for the blind in Delhi.Methods Two hundred and fifty students were selected randomly from ten schools for the blind in Delhi and screened for presenting and pinhole binocular distance vision using a modified 'E' chart and multiple pinhole occluder. Students were divided into two groups; 1/60 or better vision (likely to benefit from vision-based AT) and less then 1/60 vision, (likely to benefit from tactile/sound-based AT). Awareness of, and need for, ATs was investigated for each student with a questionnaire. Then information on barriers to using AT was obtained from students who knew about AT, felt they needed AT, but were not using them. This information was collected for a total of
