Purpose. Retinal Vein Occlusion (RVO) is a thrombotic process affecting retinal veins. The purpose of this research is to study demographic characteristics and prevalence of cardiovascular comorbidities among subjects affected by RVO. In addition, authors explore the role of each variable in determining occlusion type and severity. Subjects, materials and methods. This was a prospective observational study recruiting subjects affected by RVO and secondary macular edema. Exclusion criteria included pre-existing macular edema, recent ocular surgery (<6 months), pregnancy, diagnosis other than RVO, diabetes mellitus type I, any systemic pathology that significantly reduced life expectancy. Each participant was studied through a comprehensive medical history, cardiovascular assessment, blood testing, ocular exam, and macular OCT imaging. Results. A total of 145 eyes, 145 participants, thereof 80 males (55%) and 65 females. (45%) Mean age: 62.5 ± 14.3 SD. 61 eyes (42%) were affected by CRVO and 84 eyes (58%) by BRVO. No statistically significant differences were noted between genders. Hypertension was very prevalent (63%). Dyslipidemia was more associated with BRVO (p = 0.044). Subjects with hypertension had a mean central macular thickness (CMT) of 643 µm against a mean of 489 µm of those without hypertension. (p < 0.05). No other variable was associated with macular edema severity. Conclusions. Older age and hypertension are strong risk factors for RVO. Dyslipidemia was strongly associated with BRVO. (p=0.044) Hypertension was not only associated with RVO incidence, but also with its severity. In fact, hypertensive subjects had significantly worse macular edema. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Work-related stress (WRS) is widespread among medical doctors. WRS not only affects the physician's mental and physical well-being, but also patient care quality and the overall efficiency of the healthcare system. The aim of this study is to conduct a systematic review of the current preventive measures against mental disorders, work-related stress, and burnout among physicians. MATERIALS AND METHODS: The presentation of this systematic review is in accordance with the PRISMA statement. The methodological quality of the selected studies was assessed with specific rating tools: INSA, Newcastle Ottawa Scale, JADAD scale, and AMSTAR. English publications only were selected. No restrictions applied for publication type. Reviewers excluded articles not concerning the following topics: WRS prevention, WRS risk factors and mental disorders among physicians. Reviewers also excluded findings of less academic significance, editorial articles, individual contributions, purely descriptive studies published in scientific conferences. RESULTS: Online search r eturned 4 748 references on the following databases: PubMed (1638), Scopus (3108) and Cochrane Library (2). 36 studies were included in this review (thereof, 13 reviews and 23 original articles). Narrative reviews were rated on the INSA scale. The mean, median, and modal rating was 6. This indicates an intermediate-high quality of these studies. Systematic reviews were rated on the AMSTAR scale. The mean and median rating was 9, and the modal rating was 8. This indicates a high quality of these studies. The scores assigned to the original articles have a mean, median, and modal rating of 7. This also indicates an intermediate-high quality of these studies. CONCLUSIONS: Work-related stress and mental disorders seem to be widespread among medical practitioners. It is already a priority to adopt preventive measures against these phenomena. However, there is still no consensus on what the most effective measures are. Additional research is needed to formulate evidence-based recommendations. [ABSTRACT FROM AUTHOR]

Introduction. Uveal melanoma is the most common intraocular tumor in the adult population. It can affect any part of the uveal tract: the iris, ciliary body, and choroid. Historically, enucleation has been the mainstay of treatment for primary melanoma. In the last decade, however, radiotherapy has acquired an increasingly important role and has now become our first-line modality. However, it is still widely debated what is the most effective radiotherapy technique for this tumor. Purpose to perform a literature review on the utility of radiotherapy for primary ocular melanoma and determine the most effective radiotherapy technique. Materials and Methods. We included all systematic and narrative reviews on the topic, published between September 2007 and November 2017 on PubMed and SCOPUS. Two independent reviewers assessed the eligibility criteria for each article using the PRISMA checklist. The methodological quality of narrative and systematic reviews was evaluated with the INSA and AMSTAR checklists, respectively. Results. Our study analyzed a total of 23 studies, including 18 narrative reviews and 5 systematic reviews. Radiotherapy with Brachytherapy, Proton Therapy, SRS/SRT with gamma knife and cyber knife, are the most common choices for the treatment of primary ocular melanoma. These techniques allow for excellent lesion spread control, eye, and vision conservation, and improve overall patients' quality of life. Among the narrative reviews, the highest INSA score was 5/7, the lowest 2/7, the mean was 3.83/7 and median was 4/7. Among the systematic reviews, the highest AMSTAR score was 9/12, the lowest 4/12, the mean 5.6/7 and median 4/7. Conclusion. The number of studies available on this topic is scarce. Among those published, the methodological quality is modest, as assessed with the INSA and AMSTAR checklists. As a result, we are not able to determine what the most effective radiotherapy technique is. [ABSTRACT FROM AUTHOR]
