The ACS-NSQIP 'Pancreatectomy Risk Calculator' employs 10 easily assessable clinical parameters to assist patients and surgeons in making an informed decision regarding the risks and benefits of undergoing pancreatic resection. A risk calculator based on this prototype will become available in the future as on online ACS-NSQIP resource.
Purpose:
Fuchs corneal dystrophy (FD) is a common cause of endothelial keratoplasty. Recently, a series of FD cases treated with Descemet stripping only (DSO) demonstrated recovery of the central endothelium without transplantation of donor cells. Ripasudil, a rho kinase inhibitor, has been shown to promote corneal endothelial wound healing in animal models. This study prospectively evaluated the use of ripasudil in patients undergoing DSO for FD.
Methods:
Enrolled patients underwent DSO with or without cataract surgery, performed by 1 surgeon. On the first postoperative day, patients were assigned to topical ripasudil 0.4% (Glanatec) 4 times a day for 2 months or no ripasudil and followed up monthly for the first 6 months and then at 9 and 12 months after surgery. Endothelial cell density (ECD) and pachymetry were evaluated at each postoperative visit.
Results:
Eighteen patients were enrolled, including 8 women and 1 man in each group. Overall, patients who underwent DSO with ripasudil recovered vision more quickly (4.6 vs. 6.5 weeks, P < 0.01). In addition, the ripasudil group had a statistically significantly higher average ECD at 3, 6, and 12 months. The patients in the DSO observation group had a 10% decrease in peripheral ECD when comparing counts before surgery with counts 12 months after surgery (P < 0.05). In the DSO ripasudil group, there was no significant difference between peripheral ECD at preoperative baseline versus 12 months after surgery.
Conclusions:
DSO with topical rho kinase inhibitors may be an alternative treatment for patients with FD and a peripheral ECD greater than 1000 cells/mm2.
Analyses of AREDS2 data on natural history of GA provide representative data on GA evolution and enlargement. GA enlargement, which was influenced by lesion features, was relentless, resulting in rapid central vision loss. The genetic variants associated with faster enlargement were partially distinct from those associated with risk of incident GA. These findings are relevant to further investigations of GA pathogenesis and clinical trial planning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
