RESUMEN
PURPOSE: This study aims to provide a comprehensive overview of the clinical characteristics and epidemiology of uveal melanoma (UM) in the Portuguese population, evaluated at the National Reference Centre (NRC). METHODS: A prospective observational study was conducted, involving patients consecutively diagnosed with UM at the Portuguese NRC between July 2013 and December 2022. The study collected data on demographic and tumour characteristics, clinical staging according to the American Joint Committee on Cancer (AJCC), treatment approaches, local disease control, patient survival, and the occurrence of distant metastases. RESULTS: The study included a total of 316 patients, 53.8% female. The mean age at diagnosis was 61.8±14.2 years, and 75.0% of patients presented with symptoms. The mean annual age-adjusted incidence of uveal melanoma in Portugal between 2014 and 2022 was 2.4 cases per million (95% confidence interval [CI]: 2.1-2.8). For choroidal/ciliary body tumours, the overall cumulative survival and distant metastases-free survival (DMFS) rates at 5 years were 84.9% (95% CI: 78.7-91.1) and 79.4% (95%CI: 72.8-86.0), respectively. Notably, higher AJCC stages at presentation, the need for enucleation, and increased tumour thickness were associated with lower DSS and DMFS rates. CONCLUSION: This study represents the most extensive analysis of UM epidemiology within the Portuguese population. The findings underscore the importance of early diagnosis and treatment in UM, as lower AJCC stages and smaller tumour thickness at diagnosis correlate with improved DSS and DMFS.

Objective: The "Super Quinas" project evaluated the effectiveness of an intervention program to improve physical activity, aerobic fitness, sleep, and motor competence on children in primary school. Methods: The experimental group (n = 19) enrolled in a 12-week intervention program (one more extra-curricular activity class of 60 min per week) compared to the CG (n = 19), all aged 9-10 years. Physical activity (PA) and sleep were measured by accelerometry, and aerobic fitness was measured by Children's Yo-Yo test (YYIR1C) during the 1st week (PRE), the 6th week (DUR), and the 12th week (POST) of the intervention program. Motor Competence in PRE and POST intervention was also assessed by the Motor Competence Assessment (MCA) instrument. Heart rate (HR, assessed using HR monitors), and enjoyment level were recorded during all intervention program classes. A linear mixed model analysis (i.e., within-subject analyses) was performed. Results: Comparing the EG and CG in DUR and POST, the EG spent ~18 min and ~ 34 min more time in moderate to vigorous physical activity (MVPA) per day (p < 0.001); had ~44 min and ~ 203 min less sedentary time per day (p < 0.001); performed more 44 and 128 m in the Children's Yo-Yo test compared to CG (p < 0.001) and slept more 17 and 114 min per night (p < 0.001). In POST motor competence was significantly better (27%) in the EG compared to CG (p < 0.001). The %HRmax during the extra-curricular classes ranged between 65 and 81% (i.e., light to moderate intensities), and the enjoyment between fun and great fun. Conclusion: Our findings suggest that adding one more extra-curricular activity class of 60 min per week for 12 weeks effectively increased the levels of physical activity, aerobic fitness, sleep duration, and motor competence in children aged 9-10 years.

Cullin-RING ubiquitin ligases (CRLs) are the largest class of ubiquitin ligases with diverse functions encompassing hundreds of cellular processes. Inactivation of core components of the CRL4 ubiquitin ligase produces a germ cell defect in Caenorhabditis elegans that is marked by abnormal globular morphology of the nucleolus and fewer germ cells. We identified DDB1 Cullin4 associated factor (DCAF)-1 as the CRL4 substrate receptor that ensures proper germ cell nucleolus morphology. We demonstrate that the dcaf-1 gene is the ncl-2 (abnormal nucleoli) gene, whose molecular identity was not previously known. We also observed that CRL4DCAF-1 is required for male tail development. Additionally, the inactivation of CRL4DCAF-1 results in a male-specific lethality in which a percentage of male progeny arrest as embryos or larvae. Analysis of the germ cell nucleolus defect using transmission electron microscopy revealed that dcaf-1 mutant germ cells possess significantly fewer ribosomes, suggesting a defect in ribosome biogenesis. We discovered that inactivation of the sperm-fate specification gene fog-1 (feminization of the germ line-1) or its protein-interacting partner, fog-3, rescues the dcaf-1 nucleolus morphology defect. Epitope-tagged versions of both FOG-1 and FOG-3 proteins are aberrantly present in adult dcaf-1(RNAi) animals, suggesting that DCAF-1 negatively regulates FOG-1 and FOG-3 expression. Murine CRL4DCAF-1 targets the degradation of the ribosome assembly factor periodic trptophan protein 1 (PWP1). We observed that the inactivation of Caenorhabditis elegansDCAF-1 increases the nucleolar levels of PWP1 in the germ line, intestine, and hypodermis. Reducing the level of PWP-1 rescues the dcaf-1 mutant defects of fewer germ cell numbers and abnormal nucleolus morphology, suggesting that the increase in PWP-1 levels contributes to the dcaf-1 germline defect. Our results suggest that CRL4DCAF-1 has an evolutionarily ancient role in regulating ribosome biogenesis including a conserved target in PWP1.

PURPOSE: to describe a clinical case of ocular sarcoidosis in a patient with Autoimmune Polyglandular Syndrome Type 2 (APS-2). METHODS: an 86-year-old female diagnosed with APS-2 was referred to our uveitis department with rapid visual loss in her left eye during a 3-month period. Her best-corrected visual acuity (BCVA) was counting fingers in her left eye (OS) and 20/40 in her right eye (OD). Slit-lamp biomicroscopy was unremarkable OD but revealed granulomatous keratic precipitates OS. Fundoscopy revealed bilateral optic disc oedema and +2 and 4+ vitritis (SUN classification) in her OD and OS, respectively. RESULTS: the patient underwent chest X-Ray which revealed bilateral hilar lymphadenopathy and fibrosis. On high-resolution computed tomography of the lungs, ground-glass opacities were visible, and a diagnosis of ocular sarcoidosis was presumed. After exclusion of infectious diseases, the patient was treated with methotrexate and oral corticosteroids and there was substantial improvement of the optic nerve oedema and vitritis. At the most recent visit, 2 years later, OS BCVA was 20/50. CONCLUSION: There may be an association between ocular sarcoidosis and APS or other autoimmune disorders.
RESUMEN
AIM: To develop the first Ophthalmology joint guidelines with Paediatric Rheumatology with recommendations on the screening, monitoring and medical treatment of juvenile idiopathic arthritis-associated uveitis (JIA-U), endorsed by the Portuguese Society of Ophthalmology (SPO). METHODS: A systematic literature review was conducted to include publications up to July 14th 2020, with no language restrictions, in order to include all the international position papers/guidelines concerning the medical management of JIA-U and randomised clinical trials assessing the efficacy and safety of medical treatment in this field. We searched through MEDLINE (PubMed), Scopus, Web of Science and Cochrane Library. The Delphi modified technique to generate consensus was used. Preliminary evidence statements were subject to an anonymous agreement assessment and discussion process using an online survey, followed by further discussion and update at a national meeting. A draft of the manuscript with all recommendations was then circulated among all participants and suggestions were incorporated. The final version was again circulated before publication. RESULTS: Twenty-six recommendations were developed focusing on the following topics: general management (3), screening and follow-up of uveitis (4), treatment (17) and health education in JIA-U among patients and families (2). CONCLUSION: These guidelines were designed to support the shared medical management of patients with JIA-U and emphasize the need for a multidisciplinary approach between Ophthalmology and Paediatric Rheumatology regarding the comprehensive care of JIA-U. We acknowledge that updating these recommendations will be warranted in the future, as more evidence becomes available. KEY-WORDS: juvenile idiopathic arthritis, uveitis, biological treatment, conventional immunosuppressive treatment, multidisciplinary management, guidelines, consensus, review, Delphi Technique.

INTRODUCTION: To report the first case of a serpiginous choroiditis presenting after SARS-CoV-2 infection in a previously healthy young woman. CASE DESCRIPTION: A 41-year-old woman reported blurry vision OS 1 month after a mild SARS-CoV-2 infection. Left eye fundus examination revealed multiple peripapillary atrophic lesions, adjacent to a larger diffuse, ill-defined, yellow-whitish deep amoeboid-like patch, involving the peripapillary region and extending temporally to the fovea. Multimodal imaging including fluorescein angiography, indocyanine-green angiography, fundus autofluorescence and optical coherence tomography was consistent with serpiginous choroiditis. A complete systemic work-up was performed to exclude potential infectious or inflammatory etiologies. The active choroidal lesions responded to high dose corticosteroids, with functional improvement. Immunomodulatory therapy with methotrexate was initiated for long-term management. CONCLUSION: Serpiginous choroiditis is a rare but important sight-threatening condition that has been previously associated to viral infections, which seem to have a role in the induction and/or perpetuation of choroidal inflammation. SARS-CoV-2 infection appears to have played a role as a possible trigger for intraocular inflammation in this case. Therefore, COVID-19 patients reporting visual symptoms should be carefully evaluated in order to obtain adequate ophthalmological management to avoid irreversible visual damage.

Tumor biopsies in uveal melanoma (UM) serve mainly the purpose of prognostication and assessment of individual metastatic risk, but can be used for diagnosis in selected cases. The importance of precise information is paramount for selecting adequate surveillance protocols, patient counseling, and optimization of treatment strategies. However, intratumoral heterogeneity and sample representativity are major concerns and can interfere with the correct prediction of the patient's prognosis. We report a series of cases of UM with distinct morphologically identifiable areas, highlighting the differences in clinical behavior, as well as histopathological and genetic features.
RESUMEN
BACKGROUND/OBJECTIVES: To prospectively evaluate changes in peripapillary retinal nerve fibre layer (pRNFL), in all macular layers and in choroidal thickness (CT) in a cohort of systemic lupus erythematosus (SLE) patients without ophthalmologic manifestations. To associate those changes with ophthalmic characteristics, disease activity state, medication and systemic comorbidities. SUBJECTS/METHODS: Prospective cohort study of 68 previously diagnosed SLE patients. In two study visits (V1 and V2) at least 12 months apart, patients underwent a complete ophthalmologic examination including spectral domain-optical coherence tomography (SD-OCT) and an autoimmune disease specialist assessment. Automatic retinal segmentation was performed. pRNFL was determined globally and in the six peripapillary sectors and each macular layer thickness was determined in the nine early treatment diabetic retinopathy study (ETDRS) subfields. CT was manually measured at 13 locations in the posterior pole. Only one eye per patient was randomly selected for inclusion. Generalised linear mixed effects models were employed. RESULTS: Sixty-five patients completed the study. The median follow-up time was twelve months. At V2, pRNFL was significantly thinner globally (p = 0.006) and in the temporal inferior sector (p = 0.017). Patients under chronic medication with anticoagulants or antihypertensives had significantly thinner pRNFL in some locations. No significant changes were observed in macular layers or choroidal thickness between study visits. CONCLUSIONS: SLE patients presented early SD-OCT signs of neurodegeneration, evidenced by a progressive reduction in pRNFL thickness. Regardless of study visit, baseline chronic medication with anticoagulants or antihypertensives was associated with lower pRNFL thickness, accounting for a deleterious effect of cardiovascular risk factors.

BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic, autoimmune and multisystemic disease. Recent studies with functional and structural magnetic resonance imaging and cognitive tests report an unexpectedly high frequency of central nervous system involvement, even in patients with asymptomatic SLE. The purpose of this study was to identify early signs of retinal neurodegeneration by comparing the thickness of the peripapillary retinal nerve fiber layer (pRNFL) and all macular layers between patients with SLE without ophthalmologic manifestations and healthy controls. The effect of disease duration and systemic comorbidities was also studied. METHODS: Cross-sectional study, in which all participants underwent a complete ophthalmologic evaluation including retinal segmentation analysis with spectral domain-optical coherence tomography. Patients with SLE also received a detailed autoimmune disease specialist evaluation to assess the disease activity state and systemic involvement. For pRNFL thickness, the global and six peripapillary sectors were determined. Each macular layer thickness was determined in the nine Early Treatment Diabetic Retinopathy Study (ETDRS) subfields. A multiple linear regression analysis was performed to control for the effect of potential demographic, ophthalmic and systemic confounders. A second multivariable analysis, including patients with SLE only, was performed to assess the effect of disease-specific variables on the outcome measures. RESULTS: Sixty-eight eyes of 68 patients with SLE and 50 eyes of 50 healthy controls were considered. The pRNFL was significantly thinner in the SLE group globally (p = 0.026) and in the temporal superior (p = 0.007) and temporal (p = 0.037) sectors. In patients with SLE, chronic medication for hypercholesterolemia, hypertension and anticoagulants were associated with a significant thinning of the pRNFL. Patients with SLE presented significant thinning in the photoreceptor layer in five ETDRS areas (p < 0.05). Shorter disease duration was associated with greater photoreceptor thinning in all ETDRS subfields. Neuropsychiatric SLE, higher disease activity and cardiovascular risk factors were associated with a thinner photoreceptor layer. No differences were observed in overall retinal thickness or the remaining macular layers. CONCLUSION: Patients with SLE present early signs of retinal neurodegeneration, as evidenced by a reduction in the photoreceptor layer and pRNFL. These signs are more pronounced in patients with higher cardiovascular risk burden or neuropsychiatric involvement.
RESUMEN
PURPOSE: Regulatory T cells (Tregs) have been intensively studied in a myriad of autoimmune diseases. As for noninfectious uveitis (NIU), results have been contradictory, and studies have failed to demonstrate a consistent reduction in Treg cell frequency in patients with active disease. The present study aims to characterize T lymphocyte subsets, including naïve and memory Tregs as well as their respective CD39 expression, in the peripheral blood of NIU patients. Inflammatory as well as suppressive cytokine profiles were also evaluated. METHODS: T cell subpopulations were evaluated by multiparametric flow cytometry using anti-CD3, anti-CD4, anti-CD45, anti-CD45RA, anti-CD197, anti-CD25, anti-CD127, and anti-CD39. Treg cells were defined as CD3 + CD4+CD25hiCD127low. A multiplex bead-based immunoassay was used to determine TNF-α, IFN-É£, IL-17A, IL-10, and TGF-ß levels. RESULTS: Twenty-nine patients with active NIU were included as well as 15 sex- and age-matched controls. There were no significant differences in T lymphocyte subsets, including Tregs, between patients and controls. However, patients with a lower grade of anterior chamber or vitreous inflammatory cellular reaction showed higher memory Treg counts than controls, with no respective increase in CD39+ expression, and a tendency for higher IL-17A levels (p = 0.06). This IL-17A elevation was present in the total NIU group (p = 0.08) as well as a positive correlation between IL-17A levels and the absolute counts of memory Tregs (p = 0.013; R = 0.465). Patients with higher IL-17A levels also showed higher serum concentrations of memory (p = 0.001) and naïve (p = 0.003) Tregs as well as elevated TNF-α (p < 0.0001) and IFN-É£ (p = 0.016) levels. Negative correlations were observed between IL-10 and TGF-ß levels and the percentages of memory (p = 0.030; R = - 0.411) and total CD39+ Tregs (p = 0.051; R = - 0.373) in the peripheral blood of NIU patients. CONCLUSION: Our results showed that total Treg levels were not reduced in patients with NIU. Further characterization of Treg subsets, including memory Tregs and respective CD39 expression, may provide additional insight on the role of Treg cells in NIU. Consistent high levels of circulating IL-17A in NIU patients are in accordance with previous studies and reinforce this cytokine's vital role in uveitis pathogenesis and its possible use as a therapeutic target.

Aberrant T cell differentiation and lymphopenia are hallmarks of severe COVID-19 disease. Since T cells must race to cull infected cells, they are quick to differentiate and achieve cytotoxic function. With this responsiveness, comes hastened apoptosis, due to a coupled mechanism of death and differentiation in both CD4+ and CD8+ lymphocytes via CD95 (Fas) and serine-threonine kinase (Akt). T cell lymphopenia in severe cases may represent cell death or peripheral migration. These facets depict SARS-Cov-2 as a lympho-manipulative pathogen; it distorts T cell function, numbers, and death, and creates a dysfunctional immune response. Whether preservation of T cells, prevention of their aberrant differentiation, and expansion of their population may alter disease course is unknown. Its investigation requires experimental interrogation of the linked differentiation and death pathway by agents known to uncouple T cell proliferation and differentiation in both CD4+ and CD8+ T cells.

Uveal melanoma (UM) is the most frequent primary ocular cancer in adults, accounting for 5% of all melanomas. Despite effective treatments for the primary tumour, up to 50% of UM patients will develop metastasis, leading to a very poor prognosis and a median overall survival of 6 to 12 months, with no major improvements in the last 30 years. There is no standard oncological treatment available for metastatic UM patients, and BRAF/MEK and immune checkpoint inhibitors show disappointing results when compared to cutaneous melanoma (CM). Recent advances in biology, however, identified specific gene and chromosome alterations, potentially permitting an actively tailored surveillance strategy, and dedicated clinical studies. Being a rare cancer, UM patients have to overcome issues such as identifying referral centres, having access to information, and partnering with oncologists for specific management strategies and research priorities. Here, we describe how the EUropean Rare Adult solid CAacer Network (EURACAN) will help in addressing these challenges and accelerating international collaborations to enhance the development of innovative treatments in UM.
RESUMEN
A 17-year-old man presented to the emergency department with complaints of retro-orbital pain of the left eye and an altitudinal visual field defect for 2 weeks. Fundus examination revealed ipsilateral hyperaemic optic disc oedema, and the patient was admitted with the presumptive diagnosis of left optic neuritis. Subsequently, during follow-up, the patient developed a retinal granulomatous lesion in the superior temporal arcade with vitritis and fibrotic strands extending to the mid-periphery. Serum antibodies detection by ELISA and aqueous humour immunoblot were positive for Toxocara canis Medical therapy with albendazole and oral steroids was instituted with satisfactory results. One year later, a new macular lesion developed with consequent vision loss.

PURPOSE: To compare choroidal thickness (CT) between patients with systemic lupus erythematosus (SLE) without ophthalmologic manifestations and a control group. To study the effects in CT of disease duration, activity index, medication and systemic comorbidities. METHODS: Cross-sectional study where spectral-domain optical coherence tomography with enhanced depth imaging was used to measure CT in 13 locations, subfoveally and at 500-µm intervals along a horizontal and a vertical section from the fovea. Linear regression models were used. RESULTS: Sixty-eight SLE patients and fifty healthy controls were enrolled. CT multivariable analysis revealed lower values in SLE patients (12.93-26.73 µm thinner) in all locations, except the inferior quadrants (6.48-10.44 µm thicker); however, none of these results reached statistical significance. Contrary to the control group, the normal topographic variation in CT between macular quadrants and from the center to the periphery was not observed in the SLE group. Multivariable analysis in the SLE group alone revealed a significant negative association with anticoagulants (50.10-56.09 µm thinner) and lupus nephritis (40.79-58.63 µm thinner). Contrary to controls, the CT of SLE patients did not respond to changes in mean arterial pressure. CONCLUSION: CT in SLE appears to be thinner, particularly in the subset of patients with nephritis and taking anticoagulants, suggesting more advanced systemic vascular disease. Choroidal responses to hemodynamic changes may also be altered in SLE.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disorder that can involve any organ system. Central nervous system involvement can be a severe life threatening complication, ultimately resulting in severe neurodegenerative changes. Magnetic resonance imaging suggests that neurodegeneration, which may have deleterious effects on brain function, may occur early in SLE and experimental models suggest that neuroprotection may be feasible and beneficial. The retina is an extension of the brain. Recent ophthalmic imaging technologies are capable of identifying early changes in retinal and choroidal morphology and circulation that may reflect CNS degeneration. However, their utility in monitoring CNS involvement in SLE has been poorly studied as these have only been performed in small cohorts, in a cross-sectional design, non-quantitatively and without correlation to disease activity. The authors aim to review the current understanding of neurodegeneration associated with SLE, with particular focus on the visual pathway. We describe the neuropathology of the visual system in SLE and the evidence for retinal and choroidal neurodegenerative and microvascular changes using optical coherence tomography technology. We aim to describe the potential role of optical imaging modalities in NPSLE diagnosis and their likely impact on the study of neuronal function.
