BACKGROUND This study aims to investigate the incidence and the relative risk factors of retinopathy of prematurity (ROP) and posterior-ROP (P-ROP): ROP in Zone I and posterior Zone II, as well as to analyze the occurrence of surgical treatment of ROP and to evaluate the short term outcome of the disease in Italy. METHODS It is a prospective multicenter observational study; all infants with a...

OBJECTIVE To assess the present-day prevalence of retinopathy of prematurity (ROP) worldwide. METHODS A search of the literature was conducted to better define the worldwide experience with ROP. An interview was also conducted with 2 schools for the blind, Overbrook in Philadelphia, Pennsylvania, and Perkins in Watertown, Massachusetts. The study also is based on personal experience with ROP ...

PURPOSE To demonstrate the clinical characteristics and treatment outcomes of severe retinopathy of prematurity (ROP) in preterm infants with birth weight (BW) above 1500 g in Turkey. METHODS A retrospective review of 5920 ROP records was performed in Zeynep Kamil Maternity and Children's Diseases Training and Research Hospital. The records were obtained from ROP treatment center of the same ...

since ROP (Return Oriented Programming) has been put forward, it has broken the limit of protection strategy against malware. Finer granularity of control and complete expression make traditional defense against control flow attacks fail. In recent years, defense of ROP has made some progress. Some detection methods based on the short length of gadgets in ROP shellcode largely limit ROP. In thi...

Telemedicine has potential to improve the delivery, quality, and accessibility of ophthalmic care for infants with Retinopathy of Prematurity (ROP). Using a telemedicine screening strategy, three potential diagnostic cutoffs may be used to define disease that warrants ophthalmologic referral: presence of any ROP, presence of moderate ("type-2 prethreshold") ROP, or presence of severe ROP requir...

PURPOSE The analgesic effect of ropivacaine (Rop) for nerve block lasts only ~3-6 hours for single use. The aim of this study was to develop long-acting regional anesthetic Rop nanoparticles and investigate the effects of sciatic nerve block on postoperative pain in rats. MATERIALS AND METHODS Rop nanoparticles were developed using polyethylene glycol-co-polylactic acid (PELA). One hundred an...

PURPOSE. To prospectively study plasma levels of soluble E-selectin (sE-selectin) in premature infants and to identify their relationship to retinopathy of prematurity (ROP) on the background of known clinical risk factors. METHODS. Eighty-five sE-selectin plasma samples from 42 preterm infants born at 23 to 32 weeks of gestational age (GA) were analyzed. Twenty-two of the infants did not have ...

Nephron reduction is an important factor in the development of glomerulosclerosis. In a study of the oligosyndactyly (Os) mutation that causes a congenital 50% reduction in nephron number, we previously found that ROP Os/+ mice developed glomerulosclerosis whereas C57B1/6J Os/+ mice did not. We concluded that the predisposition to glomerulosclerosis depended largely on the genetic background, t...

OBJECTIVE To determine the risk factors and outcomes of retinopathy of prematurity (ROP) in infants with a birth weight of 1,501-2,000 g. MATERIALS AND METHODS Clinical characteristics and risk factors were compared and nonconditional logistic regression analysis was performed to determine independent predictors for ROP. RESULTS There were 54 (9.8%) cases of ROP in 553 patients with a birth...

Return-Oriented Programming (ROP) is a software exploit for system compromise. By chaining short instruction sequences from existing code pieces, ROP can bypass static code-integrity checking approaches and non-executable page protections. Existing defenses either require access to source code or binary, a customized compiler or hardware modifications, or suffer from high performance and storag...
