The purpose of this study is to simulate random and systematic RapidArc delivery errors for external beam prostate radiotherapy plans in order to determine the dose sensitivity for each error type. Ten prostate plans were created with a single 360° arc. The DICOM files for these treatment plans were then imported into an in-house computer program that introduced delivery errors. Random and syst...

objective: this study investigated the efficacy of bupivacaine wound infusion for pain control and opioid sparing effect after cesarean delivery. materials and methods: we conducted a randomized double blind, placebo controlled clinical trial on 60 parturients undergoing cesarean section at a university hospital in tehran. patients were randomized to receive a pump infusion system that was fill...

BACKGROUND The frequency of posterior presentations (occiput of the fetus towards the sacrum of the mother) in labor is approximately 20% and, of this, 5% remain posterior until the end of labor. These posterior presentations are associated with higher rates of cesarean section and instrumental delivery. Manual rotation of a posterior position in order to rotate the fetus to an anterior positio...

Data delivery of packets in broad cast using wireless medium is the main intention of this paper, this will be done through a MANETS and should achieve reliable delivery. To do this various protocols are available in the networks world with in that efficient protocol called Position based opportunistic routing protocol which holds stateless property of geographic routing. When a data packet is ...

MOTIVATION In this study, a method is reported to perform IMRT and VMAT treatment delivery verification using 3D volumetric primary beam fluences reconstructed directly from planned beam parameters and treatment delivery records. The goals of this paper are to demonstrate that 1) 3D beam fluences can be reconstructed efficiently, 2) quality assurance (QA) based on the reconstructed 3D fluences ...

Normal delivery is the process of fetal discharge and ari-ari in mothers with full-term pregnancy at time delivery, mother needs special support determining position labor because she has not had previous experience, especially primigravida mothers. The choice very important for can provide comfort facilitate progress labor. purpose this study was to determine influence both variables, namely l...

Pelvic floor dysfunction (PFD) is the term connected with different clinical conditions such as urinary incontinence, anal-fecal incontinence, pelvic organ prolapse, pelvic pain syndrome and sexual dysfunction. In women the main risk factors for PFD are pregnancy and delivery, obesity, menopause and chronic pulmonary diseases. Main risk factors for PFD associated with delivery are large fetus, ...

In this study, we aimed to determine the effects of combined spinal-epidural block on low back pain incidence after vaginal delivery. 198 patients included into the study. Patients were separated into two groups regarding labor analgesia request. Combined spinal-epidural analgesia was performed in sitting position for the first group (CSE Group, n=104). The second group consisted of women who h...

Balance Sheets—Tools for Translating Evidence into Practice Integrated care delivery systems have two inherent advantages over other health care organizations. First, we integrate the financing of care with care delivery. Second, our integrated care delivery systems position us to be able to collaboratively recommend and carry out changes in practice more effectively than other delivery systems...

-Group communications are important in Mobile Ad hoc Networks (MANETs). Multicast is an efficient method for implementing group communications. However, it is challenging to implement efficient and scalable multicast in MANET due to the difficulty in group membership management. Efficient Geographic Multicast Protocol (EGMP) uses a virtual-zone-based structure to implement scalable and efficien...
