Marjan Heidari, Bahareh Dabirmanesh, Hossein Mahdavi, Khosro Khajeh
Nowadays sensors and especially biosensors play an important role in medical diagnosis and detection of food and environment contaminations. Biosensors’ facilities have been improved significantly by using technologies such as surface plasmon resonance, microfluidics, laser, and electrochemistry. These technologies are now available on chips in micro- and nano-scale and are capable of measuring the quantity of more than one analyte at once. One branch of these sensors is the holographic (bio)sensor. Reflection holographic sensors, which are optical devices fabricated based on Bragg’s law, can diffract light with specific wavelength as they absorb or release special ions or molecule depending on their polymer structure...

Background Hospital stays and medical interventions are accompanied by worries and anxiety in children and parents. Recent studies show that hospital clowns may reduce anxiety and enhance well-being. However, so far studies are based solely on subjective measures and clowns are usually not integrated in medical routine. With this pilot study, we aim to provide both psychological and physiological evidence of positive effects of clowns' interventions in hospitalized children. Patients/Method In a consecutive randomized intervention-control group design with 31 children aged 4 to 13 years, 17 patients were accompanied by a clown prior to surgery or during ward round (intervention group) and 14 were not (control group)...

Federal public reporting and payment programs have increasingly emphasized the measurement of outcomes (such as readmission, health care-associated infections, and mortality). Yet, the criteria for assessing whether outcome measures are accurate and valid enough to use for public reporting, payment, and accreditation are not well-defined. An outcome measure should be used only if the outcome can be influenced substantially by providers (that is, a strong process-outcome link exists) and statistical adjustment can be made for differences in patient populations across providers so that differences in outcomes are truly attributable to differences in the care provided...

INTRODUCTION: Dengue is a rapidly emerging vector-borne Neglected Tropical Disease, with a 30-fold increase in the number of cases reported since 1960. The economic cost of the illness is measured in the billions of dollars annually. Environmental change and unplanned urbanization are conspiring to raise the health and economic cost even further beyond the reach of health systems and households. The health-sector response has depended in large part on control of the Aedes aegypti and Ae...

AIM: Critical care ultrasound (CCUS) has been used by many Intensive Care Units(ICUs) worldwide, so as to guiding the diagnosis and the treatment. However, none of the publications currently systematically describe the utilization of CCUS to analyze the characteristics of hemodynamics and lung pathology upon the new admission to ICU and its potential role in patients' prognosis prediction. In this retrospective clinical study, we have demonstrated and analyzed the characteristics of hemodynamics and lung pathology assessed by CCUS and investigated its potential to predict patient outcome...

Selective Serotonin Reuptake Inhibitors (SSRI) were a disqualifying medication for U.S. civil pilots before April 5, 2010. After this date, a Federal Aviation Administration policy was created that allowed airmen, on select SSRIs, a pathway to hold a valid medical certificate. The purpose of this study was to provide a detailed look at SSRIs in the U.S. pilot population since the inception of this new policy. We examined the toxicology results from fatally injured airmen in addition to outcomes concerning pilots who are participating in the program...

BACKGROUND: Uptake of proven interventions requires dedicated resources that may only result in local implementation, thus precluding international practice change. We explored international uptake through online dissemination of the fever, sugar, and swallow (FeSS) protocols from the Quality in Acute Stroke Care (QASC) trial, which showed decreased death and dependency by 15.7% 90-day poststroke. AIMS: To identify: (a) the clinical discipline of healthcare professionals who downloaded the QASC resources; (b) the purpose for downloading; (c) successful implementation of any or all the FeSS protocols; (d) barriers to implementation; and (e) associations with self-reported successful implementation...
