“…These groups are more likely to use products that contain photoallergens, such as sunscreens, and seek medical attention for dermatological complaints. Locally, men and younger adults engage in sun protection habits less regularly, which may explain their lower representation in our study 6 …”

BackgroundPhotopatch testing represents the gold standard for the diagnosis of photoallergic contact dermatitis (PACD). We aimed to identify common photoallergens in our tertiary dermatological referral centre from 2012 to 2021, to compare this to the preceding period studied, and data from other communities.MethodsWe conducted a retrospective review of all 90 patients who underwent photopatch testing at the National Skin Centre, Singapore, between 2012 and 2021.ResultsOf 90 patients, 19 (21.1%) were male, and the mean age was 41.6 years. Eighty‐four (93.3%) underwent testing to our standard sunscreen series, 10 (11.1%) to our extended series, and 73 (81.1%) to their own items. Seventeen (18.9%) were diagnosed with PACD (i.e., photocontact allergy with present or past relevance), 12 (13.3%) with ACD, and 4 (4.4%) with photoaugmented ACD. Relevant reactions were commonest to oxybenzone (8, 9.5%) and mexenone (3, 3.6%). Eleven (15.1%) had PACD to their own items, with 3 of 4 (75%) tested to ketoprofen diagnosed with PACD and the remaining 1 (25%) with photoaugmented ACD. Age, race, sex, atopy, and site of involvement were not associated with photocontact allergy. Compared to the preceding time period, the overall frequency of photocontact allergy and PACD decreased, but rates of photoallergic reactions to individual photoallergens were not significantly different.ConclusionOrganic ultraviolet absorbers such as oxybenzone and mexenone remained the most relevant photoallergens. Personal item testing was valuable, and testing to ketoprofen should be considered.

“…Among 2,989 participants, Clermont et al discovered that individuals with lower educational levels (87.1%) tended to add more salt to meals consumed at home [ 31 ]. In another study, lower educational attainment was found to be a statistically significant predictor of longer sunlight exposure(β = -0.18, p < 0.001) [ 32 ]. In a questionnaire survey conducted by researchers, participants were interviewed regarding environmental, dietary, and genetic risk factors.…”

Background Educational duration might play a vital role in preventing the occurrence and development of osteoporosis(OP). Purpose To assess the causal effect of educational duration on bone mineral density(BMD) and risk factors for OP by Mendelian randomization(MR) study. Methods The causal relationship was analyzed using data from genome-wide association study(GWAS). Inverse variance weighting (IVW) was used as the main analysis method. Horizontal pleiotropy was identified by MR-Egger intercept test, MR pleiotropy residual sum and outlier (MR-PRESSO) test. The leave-one-out method was used as a sensitivity analysis. Results The IVW results indicated that there was a positive causal relationship between educational duration and BMD (OR = 1.012, 95%CI:1.003–1.022), physical activity(PA) (OR = 1.156, 95%CI:1.032–1.295), calcium consumption (OR = 1.004, 95%CI:1.002–1.005), and coffee intake (OR = 1.019, 95%CI:1.014–1.024). There was a negative association between whole body fat mass (OR = 0.950, 95%CI:0.939–0.961), time for vigorous PA (OR = 0.955, 95%CI:0.939–0.972), sunbath (OR = 0.987, 95%CI:0.986–0.989), salt consumption (OR = 0.965, 95%CI:0.959–0.971), fizzy drink intake (OR = 0.985, 95%CI:0.978–0.992), smoking (OR = 0.969, 95%CI:0.964–0.975), and falling risk (OR = 0.976, 95%CI:0.965–0.987). There was no significant association between educational duration and lean mass, time for light-to-moderate PA, milk intake, and alcohol intake. Horizontal pleiotropy was absent in this study. The results were robust under sensitivity analyses. Conclusion A longer educational duration was causally linked with increased BMD. No causal relationship had been found between educational duration and lean mass, time for light-to-moderate PA, milk intake, and alcohol consumption as risk factors for osteoporosis.
