Foveal microvascular features following inverted flap technique for closure of large macular holes.

PURPOSE: To describe the anatomical and functional outcomes following use of the inverted flap technique (IFT) to close idiopathic macular holes (MH) of diameter greater than 400 µm. To compare the changes in the macular microvascularization following surgery in operated and healthy fellow eyes. METHODS: Retrospective study of 24 patients who underwent vitrectomy and IFT for large MH closure. The main variables were closure pattern, best corrected visual acuity (BCVA) and recovery of the external limiting membrane (ELM) and ellipsoid zone (EZ). Foveal avascular zones (FAZ) and vessel and perfusion densities, obtained by OCT angiography scans, were compared with those in healthy fellow eyes. RESULTS: Complete MH closure was achieved in 95.8% (23/24) of patients 6 months after surgery. There was a significant improvement in postoperative BCVA, from 1.0 to 0.4 logMAR (p < 0.001). The most frequent closure pattern was 1a (62.5%, 15/24), followed by 2c (12.5%, 3/24). The closure pattern was not correlated with height, minimum or maximum diameters or macular hole index (MHI) (p > 0.05). ELM and EZ recovery occurred in 87.5% and 83.3% of cases, respectively. FAZ were smaller in operated eyes than in the fellow eyes (p = 0.012). There were no differences in the vessel or perfusion densities between the operated and fellow eyes (p > 0.05). CONCLUSIONS: Use of the inverted flap technique for large MH closure provides a high rate of functional and anatomical recovery. We observed a reduction in the FAZ following surgery, with no differences in the macular microvascularization parameters, suggesting that the technique is safe.

Epiretinal neovascular membrane in Macular Telangiectasia type 2: Multimodal imaging diagnosis.

PURPOSE: To characterize an epiretinal neovascular membrane (ERNM) through multimodal imaging in the context of a patient with Macular Telangiectasia type 2 (MacTel) and ipsilateral concomitant ocular ischemic syndrome (OIS). METHODS: Case report, with ultra-wide field (UWF) retinography, fluorescein angiography (FA), swept source optical coherence tomography (ss-OCT), and OCT-angiography (OCTA). Written informed consent for patient information and images to be published was provided by the patient. Approval from the Research Ethics Committee of the Hospital was obtained for publication. CASE REPORT: Yearly follow up of a 51 year-old-female patient with advanced bilateral MacTel showed new punctate hemorrhages in all four quadrants of her right eye (OD). OCTA showed an ERNM in the superficial capillary plexus of the same eye and FA confirmed the ERNM and demonstrated peripheral ischemia. Carotid ultrasound was performed and complete right carotid artery occlusion was confirmed. These findings allowed the diagnosis of an ERNM associated with Mactel and OIS. CONCLUSIONS: Interestingly, this case shows an ERNM diagnosed by multimodal imaging in a patient with advanced MacTel and a concomitant OIS. Mactel is a neurodegenerative disease which in its neovascular stage has been associated with macular neovascular membranes, but also ERNM have recently been described by OCTA.

Perspectives of Therapeutic Drug Monitoring of Biological Agents in Non-Infectious Uveitis Treatment: A Review.

Biological drugs, especially those targeting anti-tumour necrosis factor α (TNFα) molecule, have revolutionized the treatment of patients with non-infectious uveitis (NIU), a sight-threatening condition characterized by ocular inflammation that can lead to severe vision threatening and blindness. Adalimumab (ADA) and infliximab (IFX), the most widely used anti-TNFα drugs, have led to greater clinical benefits, but a significant fraction of patients with NIU do not respond to these drugs. The therapeutic outcome is closely related to systemic drug levels, which are influenced by several factors such as immunogenicity, concomitant treatment with immunomodulators, and genetic factors. Therapeutic drug monitoring (TDM) of drug and anti-drug antibody (ADAbs) levels is emerging as a resource to optimise biologic therapy by personalising treatment to bring and maintain drug concentration within the therapeutic range, especially in those patients where a clinical response is less than expected. Furthermore, some studies have described different genetic polymorphisms that may act as predictors of response to treatment with anti-TNFα agents in immune-mediated diseases and could be useful in personalising biologic treatment selection. This review is a compilation of the published evidence in NIU and in other immune-mediated diseases that support the usefulness of TDM and pharmacogenetics as a tool to guide clinicians' treatment decisions leading to better clinical outcomes. In addition, findings from preclinical and clinical studies, assessing the safety and efficacy of intravitreal administration of anti-TNFα agents in NIU are discussed.

Microbiome in Immune-Mediated Uveitis.

In the last decades, personalized medicine has been increasing its presence in different fields of medicine, including ophthalmology. A new factor that can help us direct medicine towards the challenge of personalized treatments is the microbiome. The gut microbiome plays an important role in controlling immune response, and dysbiosis has been associated with immune-mediated diseases such as non-infectious uveitis (NIU). In this review, we gather the published evidence, both in the pre-clinical and clinical studies, that support the possible role of intestinal dysbiosis in the pathogenesis of NIU, as well as the modulation of the gut microbiota as a new possible therapeutic target. We describe the different mechanisms that have been proposed to involve dysbiosis in the causality of NIU, as well as the potential pharmacological tools that could be used to modify the microbiome (dietary supplementation, antibiotics, fecal microbiota transplantation, immunomodulators, or biologic drugs) and, consequently, in the control of the NIU. Furthermore, there is increasing scientific evidence suggesting that the treatment with anti-TNF not only restores the composition of the gut microbiota but also that the study of the composition of the gut microbiome will help predict the response of each patient to anti-TNF treatment.

Real-World Evidence for Treat-and-Extend Regimen of Ranibizumab Therapy for Macular Oedema Secondary to Branch Retinal Vein Occlusion.

The aim of this study was to evaluate the efficacy of a treat-and-extend (T&E) regimen of ranibizumab as the first-choice treatment in macular oedema (MO) secondary to branch retinal vein occlusion (BRVO). We conducted a retrospective study of 20 patients who developed MO due to BRVO treated with intravitreal ranibizumab in a T&E regimen between 2016 and 2017 with a minimum follow-up of two years. Patients were classified as complete responders if treated with ranibizumab alone or incomplete responders if salvage treatment with other medications or laser was needed. Data on best corrected visual acuity (BCVA) and central macular thickness (CMT) every 6 months were recorded. The mean BCVA (logMAR) improved from 0.60 ± 0.36 to 0.29 ± 0.44 and the CMT decreased from 559.85 ± 198.61 to 305.85 ± 11.78 µm. We found statistically significant differences between complete and incomplete responders on the average number of injections during the second year (2.46 ± 2.18 compared to 5.43 ± 1.27; p = 0.007) and change of the BCVA and CMT between both groups (p < 0.001) at 6, 12, 18 and 24 months. T&E seems to be effective in MO secondary to BRVO, improving visual function and decreasing CMT, with less need for injections.

Influence of Hurdling Clearance on Sprint Mechanical Properties in High-Level Athletes.

ABSTRACT: Jiménez-Reyes, P, Casado, A, González, JE, and Rodríguez-Fernández, C. Influence of hurdling clearance on sprint mechanical properties in high-level athletes. J Strength Cond Res 36(3): 827-831, 2022-Short hurdling races are sprint races in which athletes must also clear 10 hurdles. Assessing the force-velocity (F-V) profile in sprinting has been found useful for implementing individualized training programs and determining the mechanical effectiveness in force application. This study therefore compared the sprint mechanical F-V profile between flat and hurdle conditions to distinguish which mechanical capacity (i.e., maximum force [F0], maximum velocity [V0], or maximum power [Pmax]) is required to optimize performance in hurdling races. Twenty-two athletes (10 men and 12 women, aged: 22.4 ± 3.6 years old) competing at the national and elite performance levels conducted 2 maximal sprints of 40 m in both flat and hurdle conditions. F0, V0, FVslope, Pmax, and decrease and maximal ratio of horizontal force (DRF and RFpeak, respectively) were assessed for each condition. A higher F0 (effect size [ES] = 1.69) and a lower V0 (ES = 2.08), DRF (ES = 3.15) and RFpeak (ES = 1.31) were found in the hurdle condition than in the flat condition. No significant differences were observed between conditions for Pmax (ES = 0.01). These results support the potential of using the F-V profile to monitor sprint mechanics to optimize specific and individualized sprint training programs for hurdlers and sprinters. Coaches of hurdlers should thus consider implementing in their training routines exercises that were found to be effective on the development of F0, such as heavy load resisted sprints.

Impact of COVID-19 on Eye Care in Spain during the First Phase of the Pandemic.

BACKGROUND: The declaration of the first state of alarm for COVID-19 in March 2020 provoked changes in ophthalmological care. The objective of this study was to assess its impact on reorganising care activities, the mental health of ophthalmologists and the training of residents. METHODS: We sent an anonymous online questionnaire between August and October 2020 to consultant ophthalmologists and residents who were active during the state of alarm in Spain. We used Google Forms® software for data collection. We analysed responses according to the degree of regional impact. RESULTS: We received a total of 328 responses from the 17 Autonomous Communities. We saw that 99.4% of respondents changed their work activities with 50% reductions in surgery (94.5%) and consultations (93.0%). Furthermore, 58.8% of respondents reported increased anxiety, and 29.9% transferred to support other services, with this number reaching 49.6% in the hardest-hit regions. Training programs were greatly reduced in external consultations (90.7%), and surgical training was completely cancelled (100%). Additionally, 56.5% of trainees wanted to prolong their residence periods. CONCLUSIONS: The first wave of the pandemic produced significant changes in ophthalmology services, and these changes were more pronounced in the most affected regions. It caused a negative psychological impact on a high rate of respondents and an interruption of the training of ophthalmology residents. Predictably, the negative consequences of this delay in ophthalmological care on patients will be uneven between regions.

Short-course versus long-course therapy of the same antibiotic for community-acquired pneumonia in adolescent and adult outpatients.

BACKGROUND: Community-acquired pneumonia (CAP) is a lung infection that can be acquired during day-to-day activities in the community (not while receiving care in a hospital). Community-acquired pneumonia poses a significant public health burden in terms of mortality, morbidity, and costs. Shorter antibiotic courses for CAP may limit treatment costs and adverse effects, but the optimal duration of antibiotic treatment is uncertain. OBJECTIVES: To evaluate the efficacy and safety of short-course versus longer-course treatment with the same antibiotic at the same daily dosage for CAP in non-hospitalised adolescents and adults (outpatients). We planned to investigate non-inferiority of short-course versus longer-term course treatment for efficacy outcomes, and superiority of short-course treatment for safety outcomes. SEARCH METHODS: We searched CENTRAL, which contains the Cochrane Acute Respiratory Infections Group Specialised Register, MEDLINE, Embase, five other databases, and three trials registers on 28 September 2017 together with conference proceedings, reference checking, and contact with experts and pharmaceutical companies. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing short- and long-courses of the same antibiotic for CAP in adolescent and adult outpatients. DATA COLLECTION AND ANALYSIS: We planned to use standard Cochrane methods. MAIN RESULTS: Our searches identified 5260 records. We did not identify any RCTs that compared short- and longer-courses of the same antibiotic for the treatment of adolescents and adult outpatients with CAP.We excluded two RCTs that compared short courses (five compared to seven days) of the same antibiotic at the same daily dose because they evaluated antibiotics (gemifloxacin and telithromycin) not commonly used in practice for the treatment of CAP. In particular, gemifloxacin is no longer approved for the treatment of mild-to-moderate CAP due to its questionable risk-benefit balance, and reported adverse effects. Moreover, the safety profile of telithromycin is also cause for concern.We found one ongoing study that we will assess for inclusion in future updates of the review. AUTHORS' CONCLUSIONS: We found no eligible RCTs that studied a short-course of antibiotic compared to a longer-course (with the same antibiotic at the same daily dosage) for CAP in adolescent and adult outpatients. The effects of antibiotic therapy duration for CAP in adolescent and adult outpatients remains unclear.

Sex-differences in elite-performance track and field competition from 1983 to 2015.

The purpose of this study was to assess the veracity of the Court of Arbitration for Sport's assertion that sex-differences in athletic performance in elite-standard track and field competition is of the order of 10-12%. Exponential curves were fitted to the data of selected track and field events of the finals of all IAAF World Championships and Olympic Games from 1983 to 2016. For each curve, the coefficient of determination R2 was calculated, in combination the corresponding 95% confidence intervals for the curve constants. Sex-differences were evaluated via differences in the fitted curves between men and women. Mean performances of winners, as well as overall performance means of all participants, were also analyzed. The calculated sex-difference was 8.2 ± 1.0% - 11.8 ± 2.1% for sprints, 10.3 ± 3.3% - 12.8 ± 4.0% for middle and long-distance events, 9.7 ± 2.9% - 13.1 ± 2.9% for relays and 14.2 ± 2.2% - 25.0 ± 4.4% for jumps. This study therefore confirms that the percentage difference accepted by the CAS is appropriate for elite-standard track and field events.
