OBJECTIVE We conducted a meta-analysis of the published randomized clinical trials of vitamin E prophylaxis designed to reduce retinopathy of prematurity (ROP) to determine whether increased serum concentrations of vitamin E reduced the incidence of severe, threshold (Stage 3+) ROP in the very low birth weight (VLBW) infant subset. STUDY DESIGN Among the six trials considered eligible for ana...

purpose: to determine the frequency and severity of retinopathy of prematurity (rop) among singleton and multiple-birth neonates referred to farabi eye hospital, tehran-iran. methods: we reviewed the records of 99 consecutive neonates from multiple-gestation pregnancies including 68 twins, 26 triplets and 5 quadruplets who were screened for rop during 2002-2004. the frequency, severity and risk...

We implement a volume-of-fluid algorithm with a parabolic re-construction of the interface for the calculation of the surface tension force VOF-PROST). This achieves higher accuracy for drop deformation simulations in comparison with existing VOF methods based on a piecewise inear interface re-construction. The algorithm is formulated for the Giesekus constitutive law. The evolution of a drop s...

AIM To report the Karnataka Internet Assisted Diagnosis of Retinopathy of Prematurity (KIDROP) program for retinopathy of prematurity (ROP) screening in underserved rural areas using an indigenously developed tele-ROP model. MATERIALS AND METHODS KIDROP currently provides ROP screening and treatment services in three zones and 81 neonatal units in Karnataka, India. Technicians were trained to...

PURPOSE To determine the differences in risk factors for retinopathy of prematurity (ROP) in paired twins. METHODS A retrospective medical record review was performed for all paired twins screened for ROP between 2007 and 2012. Screening was offered to very low birth weight (≤ 1500 grams) and preterm (≤ 32 weeks) neonates. Twins 1 and 2 were categorized based on the order of delivery. Materna...

The vision of a well-integrated supply chain (SC) was developed as early 1958 by Forrester, who addressed what would eventually be called the Bullwhip Effect (BWE). Flowcasting concept, originally Retail Resource Planning, proposed to connect all SC upper tiers storefront through fulfillment logic based on Distribution Planning (DRP) system. This method can therefore understood fully or SC-wide...

This study aims to analyze and show how calculate EOQ prove that the use of method can make inventory costs efficient because number purchases is not excessive lacking, frequency exact time reordering. The theory underlying this research management, especially Single Item Method. analysis technique used descriptive using Optimalization , purchase (N), Reorder Point (ROP) results showed cost eff...

Penelitian ini bertujuan untuk menganalisis jumlah persediaan bahan baku tepung terigu yang optimal, mengetahui dan stok pengaman (safety stock), waktu pemesanan kembali (Reorder Point) total biaya terigu. Alat analisis digunakan dalam penelitian adalah EOQ (Economic Order Quantity), ROP Point), Safety Stock, TIC (Total Inventory Cost). Berdasarkan hasil menggunakan metode EOQ, Jumlah optimum d...

OBJECTIVE Retinopathy of prematurity (ROP) is a leading cause of adverse visual outcomes in premature infants. Both laser photocoagulation and cryotherapy have been demonstrated in clinical trials to be efficacious in reducing the incidence of visual loss occurring secondary to threshold ROP. Visual data recently have become available concerning the long-term clinical efficacy of both treatment...

Retinopathy of prematurity (ROP) appears to be a multifactorial disease, the prevention of which is probably impossible even with the most accurate methods of blood-gas monitoring and oxygen restrictions. The oxidative processes and consequent formation of free radicals are probably influenced by the availability of various antioxidants in the immature retina. Bilirubin, the end product of haem...
