Short-Term Outcomes After COVID-19-Related Treatment Interruption Among Patients with Neovascular Age-Related Macular Degeneration Receiving Intravitreal Bevacizumab

Purpose: To assess outcomes and recovery strategy of patients undergoing intravitreal injections for exudative age-related macular degeneration who experienced COVID-19 related interruption in treatment during complete lockdown. Methods: This was a retrospective, observational case study. We used a mixed effect model with random intercepts to evaluate best corrected visual acuity (BCVA) accounting for measured central macular thickness (CMT) and individual variability of each eye. Furthermore, we analysed measures of the pigmented epithelium detachment as well as presence of subretinal fluid and intraretinal cysts. Results: We included 39 patients and we found a significant reduction in the BCVA between the pre- and post-lockdown controlling for CMT. There was no significant difference in pigmented epithelium detachment and in presence of subretinal fluid and intraretinal cysts. Conclusion: We detected a significant loss in visual function. The magnitude of the average loss was, however, limited suggesting good efficacy of the recovery strategy

Curcumin in Retinal Diseases: A Comprehensive Review from Bench to Bedside

Recent evidence in basic science is leading to a growing interest in the possible role of curcumin in treating retinal diseases. Curcumin has been demonstrated to be able to modulate gene transcription and reduce ganglion cell apoptosis, downgrade VEGF, modulate glucose levels and decrease vascular dysfunction. So far, the use of curcumin has been limited by poor bioavailability; to overcome this issue, different types of carriers have been used. Multiple recent studies disclosed the efficacy of using curcumin in treating different retinal conditions. The aim of this review is to comprehensively review and discuss the role of curcumin in retinal diseases from bench to bedside

Effect of Systemic Hypertension With Versus Without Left Ventricular Hypertrophy on the Progression of Atrial Fibrillation (from the Euro Heart Survey).

Hypertension is a risk factor for both progression of atrial fibrillation (AF) and development of AF-related complications, that is major adverse cardiac and cerebrovascular events (MACCE). It is unknown whether left ventricular hypertrophy (LVH) as a consequence of hypertension is also a risk factor for both these end points. We aimed to assess this in low-risk AF patients, also assessing gender-related differences. We included 799 patients from the Euro Heart Survey with nonvalvular AF and a baseline echocardiogram. Patients with and without hypertension were included. End points after 1 year were occurrence of AF progression, that is paroxysmal AF becoming persistent and/or permanent AF, and MACCE. Echocardiographic LVH was present in 33% of 379 hypertensive patients. AF progression after 1 year occurred in 10.2% of 373 patients with rhythm follow-up. In hypertensive patients with LVH, AF progression occurred more frequently as compared with hypertensive patients without LVH (23.3% vs 8.8%, p = 0.011). In hypertensive AF patients, LVH was the most important multivariably adjusted determinant of AF progression on multivariable logistic regression (odds ratio 4.84, 95% confidence interval 1.70 to 13.78, p = 0.003). This effect was only seen in male patients (27.5% vs 5.8%, p = 0.002), while in female hypertensive patients, no differences were found in AF progression rates regarding the presence or absence of LVH (15.2% vs 15.0%, p = 0.999). No differences were seen in MACCE for hypertensive patients with and without LVH. In conclusion, in men with hypertension, LVH is associated with AF progression. This association seems to be absent in hypertensive women

Progression From Paroxysmal to Persistent Atrial Fibrillation. Clinical Correlates and Prognosis

Objectives: We investigated clinical correlates of atrial fibrillation (AF) progression and evaluated the prognosis of patients demonstrating AF progression in a large population. Background: Progression of paroxysmal AF to more sustained forms is frequently seen. However, not all patients will progress to persistent AF. Methods: We included 1,219 patients with paroxysmal AF who participated in the Euro Heart Survey on AF and had a known rhythm status at follow-up. Patients who experienced AF progression after 1 year of follow-up were identified. Results: Progression of AF occurred in 178 (15%) patients. Multivariate analysis showed that heart failure, age, previous transient ischemic attack or stroke, chronic obstructive pulmonary disease, and hypertension were the only independent predictors of AF progression. Using the regression coefficient as a benchmark, we calculated the HATCH score. Nearly 50% of the patients with a HATCH score >5 progressed to persistent AF compared with only 6% of the patients with a HATCH score of 0. During follow-up, patients with AF progression were more often admitted to the hospital and had more major adverse cardiovascular events. Conclusions: A substantial number of patients progress to sustained AF within 1 year. The clinical outcome of these patients regarding hospital admissions and major adverse cardiovascular events was worse compared with patients demonstrating no AF progression. Factors known to cause atrial structural remodeling (age and underlying heart disease) were independent predictors of AF progression. The HATCH score may help to identify patients who are likely to progress to sustained forms of AF in the near future. \ua9 2010 American College of Cardiology Foundation

The impact of moderate to severe osteoarthritis on the physical performance and quality of life: a cross-sectional study in Greek patients (PONOS study)

Abstract Background Osteoarthritis (OA) represents a leading cause of disability with limited data available for the Greek patients. Objectives To evaluate the impact of moderate to severe symptomatic hip/knee OA under treatment on physical performance and quality of life. Methods A non-interventional, cross-sectional, epidemiological study of patients with moderate/severe OA, recruited in a single visit from 9 expert sites in Athens, Greece. Assessments were based on commonly used outcome scales: the Hip disability and Osteoarthritis Outcome Score (HOOS), the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the EuroQol-5-Dimensions 3-levels questionnaire (EQ-5D-3L). Results One hundred sixty-four patients were included in the analysis. Most of the patients were females (78.7%), with a mean age of 70.5 ± 10.2 years. Comorbidities were reported by 87.2% of patients with hypertension being the most frequently reported (53.7%), followed by dyslipidemia (31.1%), obesity (24.4%) and diabetes mellitus (23.2%). Paracetamol was the most common treatment (96%), followed by NSAIDs (75%), opioids (50%) and locally applied medications (42.7%). Both hip and knee OA patients showed substantial deterioration in health-related quality of life (QoL) and health status as reflected by the HOOS/KOOS (Function in sport and recreation was the most impaired subscale, followed by Hip- or Knee-related QoL). The mean EQ-5D-3L index score was 0.396 ± 0.319 and the mean EQ-VAS score was 52.1 ± 1.9. When compared indirectly to the local population norms our OA population had worse QoL indices. Conclusion Our findings suggest the functional disability and impaired QoL of Greek patients with moderate/severe hip/knee OA under treatment emphasizing the need for novel treatments that will reduce the burden of the disease

A novel quantitative analysis method for idiopathic epiretinal membrane

Purpose To introduce a novel method to quantitively analyse in three dimensions traction forces in a vast area of the ocular posterior pole. Methods Retrospective analysis of 14 eyes who underwent peeling surgery for idiopathic, symptomatic and progressive epiretinal membrane. The technique measures the shift in position of vascular crossings after surgery from a fixed point, which is the retinal pigmented epithelium. This shift is defined as the relaxation index (RI) and represents a measure of the post-operative movement of the retina due to released traction after surgery. Results Best-corrected visual acuity was significantly better than baseline at all follow ups while the RI had its maximum value at baseline. Moreover, we found a significant correlation between best-corrected visual acuity at 6 months and RI at baseline. Conclusion While all previous published methods focused on bidimensional changes observed in a small region, this study introduces a three-dimensional assessment of tractional forces. Future integration of RI into built-in processing software will allow systematic three-dimensional measurement of intra retinal traction

“So Precisely What Will You Use Your Trade Mark for?” Bad Faith and Clarity in Trade Mark Specifications

The requirements for the specification setting out the list of goods and services covered by a trade mark registration are rarely considered in the literature or by the courts. The reference in C-371/18 Sky v Skykick will enable to Court of Justice to consider two critical issues connected with the precision of the specification: whether clarity of the specification is a substantive requirement and whether it is necessary to intend to use the mark on the date of filing. It is argued here that the Court of Justice should find that clarity is a substantive requirement for the registration of a trade mark and confirm that a lack of intention to use a mark is a type of bad faith which can lead to (partial) revocation of the trade mark
