Optical coherence tomography angiography as a future diagnostic tool in sports medicine?
CONCLUSION: Differences were found in the OCTA measurements of the FAZ depending on the individual physical fitness. Performing HIIT can induce significant changes in certain OCTA parameters. Therefore, OCTA imaging appears to be a promising imaging modality in the field of sports medicine.

Acute and chronic effects of soccer game on the retinal vessel diameters in middle-aged adults.
CONCLUSIONS: In middle-aged amateur soccer players, improvement of the retinal microcirculation was observed. Cardiovascular risk factors and physical inactivity were associated with adverse retinal microvascular alterations. In terms of acute effects, soccer play causes venular, but not arteriolar dilatation for middle-aged adults.

Oxidative stress, lipid peroxidation indexes and antioxidant vitamins in long and middle distance athletes during a sport season.
CONCLUSIONS: i) physical training improves the antioxidant systems in order to reduce lipid peroxidation in trained athletes along the season; ii) PUFA/SFA ratios seem more reliable than MDA to observe oxidative stress.

Doubles trouble-85 cases of ocular trauma in badminton: clinical features and prevention.
CONCLUSION: The vast majority of the badminton related eye injuries occurred among doubles players and were instigated by the injured person's partner. Non-penetrating injury was more frequent; penetrating injury was usually more serious. We recommend that badminton players use protective eyewear and receive safety education and professional coaching/instruction on techniques to protect against serious eye injuries.

Acute effects of high-intensity interval training on cognition and retinal microcirculation in experienced amateur boxers.
CONCLUSIONS: At the functional level, an improvement in executive function due to intermittent high-intensity punching load was observed, while at the physiological level, retinal venular dilatation was observed in experienced amateur boxers.

The effect of combined exercises on the plasma levels of retinol-binding protein 4 and its relationship with insulin resistance and hepatic fat content in postmenopausal women with nonalcoholic fatty liver disease
CONCLUSIONS: Combined exercises significantly reduced serum levels of RBP4 in postmenopausal women with fatty liver. RBP4 was not related to insulin resistance and effects of RBP4 on hepatic fat regulation were independent of the effects of insulin resistance.PMID:33871240 | DOI:10.23736/S0022-4707.21.12233-9

A Traditional Chinese Patent Medicine ZQMT for Neovascular Age-Related Macular Degeneration: a multicenter randomized clinical trial.
CONCLUSION: The combinatory therapy of ranibizumab and traditional Chinese patent medicine ZQMT had equivalent effects on visual acuity improvement and safety profiles as the ranibizumab treatment alone. Ranibizumab injections coupled with ZQMT offer therapeutic advantages in terms of reduction of retinal lesions and eases the financial burden of patients undergoing treatment by reducing the frequency of necessary ranibizumab injections.

Ubiquitous Chromatin Modifiers in Congenital Retinal Diseases: Implications for Disease Modeling and Regenerative Medicine.
Abstract
Retinal congenital malformations known as microphthalmia, anophthalmia, and coloboma (MAC) are associated with alterations in genes encoding epigenetic proteins that modify chromatin. We review newly discovered functions of such chromatin modifiers in retinal development and discuss the role of epigenetics in MAC in humans and animal models. Further, we highlight how advances in epigenomic technologies provide foundational and regenerative medicine-related insights into blinding disorders. Combining knowledge of epigenetics and pluripotent stem cells (PSCs) is a promising avenue because epigenetic factors...

Stem Cell-Based RPE Therapy for Retinal Diseases: Engineering 3D Tissues Amenable for Regenerative Medicine.
Authors: Ben M'Barek K, Habeler W, Monville C
Abstract
Recent clinical trials based on human pluripotent stem cell-derived retinal pigment epithelium cells (hPSC-RPE cells) were clearly a success regarding safety outcomes. However the delivery strategy of a cell suspension, while being a smart implementation of a cell therapy, might not be sufficient to achieve the best results. More complex reconstructed tissue formulations are required, both to improve functionality and to target pathological conditions with altered Bruch's membrane like age-related macular degeneration (AMD). Herein, we describe the various opti...

PERSPECTIVES Small Heat Shock Proteins, Amyloid Fibrils, and Nicotine Stimulate a Common Immune Suppressive Pathway with Implications for Future Therapies
The α7 nicotinic acetylcholine receptor (α7nAChR) is central to the anti-inflammatory function of the vagus nerve in a physiological mechanism termed the inflammatory reflex. Studies on the inflammatory reflex have been instrumental for the current development of the field of bioelectronic medicine. An independent investigation of the biological role of αB-crystallin (HspB5), the most abundant gene transcript present in active multiple sclerosis lesions in human brains, also led to α7nAChR. Induction of experimental autoimmune encephalomyelitis (EAE) in HspB5–/– mice results in greater p...

A Narrative Review of Common Uses of Ophthalmic Ultrasound in Emergency Medicine
The timely evaluation of ocular conditions in the emergency department (ED) can be difficult due to a general lack of specialized equipment, trained personnel, and the time-sensitive nature of emergent ocular conditions. Recently, the use of ocular point-of-care ultrasound (POCUS) has been shown to be particularly useful in the ED. POCUS can be used to promptly diagnose various ocular pathologies, which include ocular trauma, vitreous hemorrhage, central retinal artery occlusion, and retinal detachment.
