At the 24-month follow-up, the cumulative proportions of trabeculotomy success in the SEVAN and MEVAN groups were 89.7% and 36.0%, respectively. Patients with MEVAN and larger preoperative corneal diameter (per 0.5 mm) were more likely to experience failed trabeculotomy (hazards ratio [HR], 7.997 [95% CI, 1.640-38.996], p = 0.010; 1.853 [95% CI, 1.128-3.042], p = 0.015). Epacadostat order CONCLUSION Hemangiomas exhibited different distribution patterns between SEVAN and MEVAN. Trabeculotomy had a poorer prognosis in young SWS patients with MEVAN than in those with SEVAN. In addition to anterior chamber angle anomalies, vascular factors may contribute to the aetiology of SWS early-onset glaucoma. © 2020 Acta Ophthalmologica Scandinavica Foundation.

METHODS Retrospective analysis of a longitudinal cohort of 21 VHL germline mutation carriers and RH. Clinical and genetic data were obtained to analyse the correlation of genotype with phenotype and treatment outcomes. RESULTS All patients were categorized in two genotypic categories missense mutations (MM) and truncating mutations (TM). Mean follow-up duration was 16.3 years and did not differ significantly between mutation groups (p = 0.383). Missense mutations (MM) carriers (n = 6) developed more progression-related complications compared to TM carriers (n = 15) (p = 0.046). Vitreoretinal surgery was more often applied in MM carriers (p = 0.036). Moderate (visual acuity (VA)20/80 to 20/200) to severe (VA  less then  20/200) visual impairment was observed in 53.3% of the eyes of MM carriers and 28.1% of the eyes of TM carriers at last recorded visit. CONCLUSION Missense mutations in VHL patients seem to have a higher prevalence of progression-related complications. Missense mutations (MM) carriers required therefore more often vitreoretinal surgical treatment with a worse treatment outcome. Genetic analysis may play a role in determining a pro-active treatment strategy and prognosis for RH. © 2020 The Authors.

This study aimed to evaluate the impact of caring on caregivers of amputated patients with type 2 diabetes and diabetic foot. A cross-sectional study included a convenience sample of 110 caregivers who answered the Burden Assessment Scale, the Depression Anxiety Stress Scales, the Social Support Satisfaction Scale, the Family Assessment Device, and the Short Form Health Survey. Multiple linear hierarchical regressions were performed to identify the variables that contributed to the burden and the physical and mental quality of life. Differences in burden as well as physical and mental quality of life were found, according to several caregivers’ sociodemographic characteristics. Lower social support, more distress, and caregiver's perception of the impact of caring on the family dynamics contributed to burden. Lower distress and not having a chronic illness besides diabetes explained the physical quality of life whereas exercise and lower distress explained mental quality of life. To promote quality of life in caregivers and reduce the burden associated with caregiving, interventions should focus on social support, distress, and the practice of exercise.PURPOSE To characterize the effectiveness measures of cost-effectiveness studies (CES) of ophthalmic drugs. METHODS A systematic review was conducted in PubMed/Embase until October 2019. Cost-effectiveness studies (CES) evaluating ophthalmic drugs were included. Sources of effectiveness measures were extracted. Data on study design and study outcomes were extracted from sources of effectiveness measures. The adequacy of the sample size of the clinical studies used as sources of effectiveness measures was assessed. If CES have retrieved effectiveness data from multiple sources, the appropriateness of the method to combine the results was analysed. RESULTS Forty-five CES were included. Thirty-one (68.9%) retrieved their effectiveness measures from experimental studies, five (11.1%) from observational studies and nine (20%) from other type of data sources. Eight (17.8%) CES used data from a primary outcome of a study as an effectiveness measure, eight (17.8%) used data from secondary outcomes, seven (15.6%) used data from the both primary and secondary outcomes and for 22 (48.9%) it was not possible to identify the outcomes used. From the 23 (51.1%) CES based on a single clinical study, three (6.7%) included data from clinical studies which had an adequate sample size to detect significant differences in the clinical outcomes used as effectiveness measures. From the 17 (37.8%) CES based on multiple clinical studies, only one (2.2%) used and/or reported an adequate method of quantitative synthesis (meta-analysis). CONCLUSION A considerable number of CES in ophthalmology were not based on clinical studies with adequate sample sizes and report results from effectiveness measures not assessed as primary outcomes. © 2020 Acta Ophthalmologica Scandinavica Foundation.

R. Br. The modulation was performed by using a dual second dimensional columns interface combined with a make-up dilution pump, which is responsible for dilution and neutralization of the first dimensional effluent, and the dual second dimensional columns integrated the trapping and the separation function to reduce the second dimension system dead volume. Taking advantage of the dissociable characteristics of alkaloids, mobile phases with different pH values were applied in the first dimension (pH 9.0) and the second dimension (pH 2.6) to improve the orthogonality of two-dimension separation. Besides, the pulse elution gradient in first dimension and second dimensional gradient were carefully optimized and much better separation was achieved compared to the separation with the traditional two-dimensional liquid chromatography approach.
