Development of cognition decline in non-acute symptomatic patients with cerebral small vessel disease: Non-Acute Symptomatic Cerebral Ischemia Registration study (NASCIR)--rationale and protocol for a prospective multicentre observational study
This study aims to investigate risk factors, clinical course, cerebral and retinal imaging changes, proteomics features of non-symptomatic ischaemia symptomatic patients with cognitive decline. Methods and analysis The Non-Acute Symptomatic Cerebral Ischemia Registration study is a multicentre, registry-based, prospective observational study, is designed to investigate the cognitive decline in non-acute ischaemia symptomatic patients. We will recruit 500 non-acute ischaemia symptomatic patients from four tertiary hospitals in China. For this study, non-acute ischaemia symptoms will be defined as headaches, dizziness and m...

Endovascular treatment of anterior cranial base dural arteriovenous fistulas as a first-line approach: a multicenter study
CONCLUSIONS: Most anterior cranial base DAVFs can be successfully treated via an endovascular approach. Neurological and visual complications are rare, even if the ophthalmic artery is used as the primary access route. Efforts should be focused on prospectively comparing the results of EVT and surgical management.PMID:35395632 | DOI:10.3171/2022.2.JNS212588

Prevalence and associated relating factors in patients with hereditary retinal dystrophy: a nationwide population-based study in Taiwan
CONCLUSIONS: 74% of the diagnosed HRD are retinitis pigmentosa. Population-based data suggested an increased incidence of cataract in younger patients, whereas older HRD patients are more susceptible to develop CME. Further work is needed to elucidate the mechanism between these ophthalmological disorders and HRD.PMID:35396285 | DOI:10.1136/bmjopen-2021-054111

What the Science Says About the Health Benefits of Vitamins and Supplements
From multivitamins and melatonin to fiber and fish oil, Americans who are trying to boost their health and immunity have a plethora of supplements to choose from. An estimated 58% of U.S. adults ages 20 and over take dietary supplements, according to the U.S. Centers for Disease Control and Prevention, and the supplement industry is valued at more than $30 billion a year. Supplement use has been growing rapidly over the past few decades along with the wellness industry. “The popular belief is that a supplement is going to be helpful for promoting health,” says Fang Fang Zhang, a professor at Tufts University&rs...

The New Era of Retinal Imaging in Hypertensive Patients
Structural and functional alterations in the microcirculation by systemic hypertension can cause significant organ damage at the eye, heart, brain, and kidneys. As the retina is the only tissue in the body that allows direct imaging of small vessels, the relationship of hypertensive retinopathy signs with development of disease states in other organs have been extensively studied; large-scale epidemiological studies using fundus photography and advanced semi-automated analysis software have reported the association of retinopathy signs with hypertensive end-organ damage includes the following: stroke, dementia, and coronar...

Goldfish and crucian carp are natural models of anoxia tolerance in the retina
Comp Biochem Physiol A Mol Integr Physiol. 2022 May 23:111244. doi: 10.1016/j.cbpa.2022.111244. Online ahead of print.ABSTRACTVertebrates need oxygen to survive. The central nervous system has an especially high energy demand, so brain and retinal neurons quickly die in anoxia. But fish of the genus Carassius are exceptionally anoxia-tolerant: the crucian carp (C. carassius) can survive months without oxygen in ice-covered ponds, and the common goldfish (C. auratus) can withstand hours of anoxia at room temperature. These fish previously offered insights into anoxia tolerance in the brain, heart, and liver. Here, we advanc...
