High-resolution CT angiogram (CTA) has replaced traditional diagnostic angiography as the main preoperative imaging modality for vascular surgery patients. Although the use of CTA is increasing for arterial imaging, it has not been used routinely for vein mapping. The goal of this study was to evaluate the accuracy of CTA for venous anatomy and compare it to a standard venous duplex ultrasound (DUS). When the vein was used for bypass, the quality and size of the vein were evaluated in the operating room. As part of a preoperative workup before lower extremity revascularization, 16 patients underwent a CTA followed by a DUS...

The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT). This was a prospective study using results from chest radiographs, electrocardiograms, and questionnaires to investigate the participants' respiratory symptoms, sedentarism, and comorbidities (Charlson comorbidity index)...

Sleep apnea, characterized by frequent pauses in breathing during sleep, poses a serious threat to the healthy growth and development of children. Polysomnography (PSG), the gold standard for sleep apnea diagnosis, is resource intensive and confined to sleep laboratories, thus reducing its accessibility. Pulse oximetry alone, providing blood oxygen saturation (SpO2) and blood volume changes in tissue (PPG), has the potential to identify children with sleep apnea. Thus, we aim to develop a tool for at-home sleep apnea screening that provides a detailed and automated 30 sec epoch-by-epoch sleep apnea analysis...

A quasi-experimental study was performed on 20 technicians working in the Faculty of Medicine, Mansoura University, Egypt. The knowledge, attitude, and practice (KAP) of laboratory technicians was measured before and two months after enrolling them in an intervention programme about laboratory best practice procedures. The programme addressed laboratory safety and medical waste management. The assessment was performed using a validated Arabic self-administered questionnaire. Pre- and post-intervention scores were compared using non-parametric tests...

PURPOSE: The aim of this study was to evaluate the efficacy of a structured communication protocol between dentists and dental laboratory technicians. MATERIALS AND METHODS: A total of 112 single metal-ceramic crowns, fabricated by four different dentist-dental technician pairs, were evaluated at the clinical try-in appointment. Subsequently, each professional pair produced another 112 crowns using a checklist. RESULTS: The scores showed a statistically significant improvement in clinical outcomes with the use of a checklist by reducing adjustment times for contact area, fit, and occlusion and number of appointments...

This article outlines the evolution of a rescue team in responding to adenovirus prevention with a deployable field hospital. The local governments mobilized a shelter hospital and a rescue team consisting of 59 members to assist with rescue and response efforts after an epidemic outbreak of adenovirus. We describe and evaluate the challenges of preparing for deployment, field hospital maintenance, treatment mode, and primary treatment methods. The field hospital established at the rescue scene consisted of a medical command vehicle, a computed tomography shelter, an X-ray shelter, a special laboratory shelter, an oxygen and electricity supply vehicle, and epidemic prevention and protection equipment...

C T Smith, K E Diefenderfer
Fabricating accurate cast gold restorations can be challenging for both clinicians and laboratory technicians. Removing the wax pattern from the master die often distorts the pattern, which, in turn, compromises the overall fit and marginal adaptation of the casting. This article demonstrates a laboratory technique in which the final restoration is cast directly on the refractory die without removing the wax pattern. Thus, distortion of the wax pattern is avoided, enabling the production of superbly fitting gold castings for both intracoronal and extracoronal restorations...

High-throughput screening (HTS) strategies and protocols have undergone significant development in the last decade. It is now possible to screen hundreds of thousands of compounds, each exploring multiple biological phenotypes and parameters, against various cell lines or model systems in a single setting. However, given the vast amount of data such studies generate, the fact that they use multiple reagents, and are often technician-intensive, questions have been raised about the variability, reliability and reproducibility of HTS results...

BACKGROUND: CD4 T-cell counts are widely used to assess treatment eligibility and to follow-up HIV-infected patients. The World Health Organization prequalification of in vitro diagnostics program conducted a performance evaluation of the FACSPresto (BD Biosciences), a new point-of-care instrument to measure absolute CD4-T cell (CD4) counts and percentages in venous and capillary blood samples from HIV-infected patients. METHODS: Patients were recruited in Belgium (200 patients) and in Tanzania (247 patients)...

Since the Syrian civil war began in 2011, most of the Syrian refugees have immigrated to Turkey due to its open gate policy and the width of the border. By the end of 2015, it was estimated that there were 2.5 million Syrian refugees in Turkey. Many of the Syrian refugees live in Sanliurfa due to its location on the border with Syria. Trichomonas vaginalis, apart from viral agents is the most common parasite among sexually transmitted infection agents. The aim of this study was to determine the prevalence of T...

Worldwide, it is estimated that 140 million people suffer from shigellosis annually. The traditional identification of Shigella spp. by culture lacks sensitivity. Rapid diagnosis of shigellosis is important because it allows to engage appropriate antimicrobial treatment that shortens the duration and severity of the illness and reduces microbial carriage, thus the spread of infection in the community. Onestep immunochromatographic dipstick tests have been successfully developed at Institut Pasteur for Shigella spp...

BACKGROUND: Roll-out and implementation of antiretroviral therapy (ART) necessitated many countries in Sub-Saharan Africa to strengthen their national health laboratory systems (NHLSs) to provide high quality HIV diagnostic and supportive services. This study was conducted to assess the performance of health laboratories in provision of HIV diagnostic and supportive services in eight districts (from four regions of Iringa, Mtwara, Tabora and Tanga), after nine years of implementation of HIV/AIDS care and treatment plan in Tanzania...

There is a significant interest in developing inexpensive portable biosensing platforms for various applications including disease diagnostics, environmental monitoring, food safety, and water testing at the point-of-care (POC) settings. Current diagnostic assays available in the developed world require sophisticated laboratory infrastructure and expensive reagents. Hence, they are not suitable for resource-constrained settings with limited financial resources, basic health infrastructure, and few trained technicians...
