Cecil A Rambarat, David E Winchester
An elderly man was transferred to our emergency department with reported ventricular tachycardia requiring intravenous amiodarone and intensive care unit admission. Device interrogation, the following day, revealed only frequent premature ventricular contractions and non-sustained ventricular tachycardia in a patient with a known history of these conditions. The patient underwent unnecessary invasive monitoring after being emergently transferred to our facility and admitted to the intensive care unit. Fortunately, our patient did not suffer any unwarranted side effects from intravenous amiodarone...

OBJECTIVE: The minimally invasive approach to colorectal surgery is still underused. Only 50% to 60% of colectomies and 10% to 20% of rectal resections for cancer are performed laparoscopically. The increasing adoption of the robotic platform for colorectal surgery warrants re-evaluation of minimally invasive surgery (MIS) training techniques. Although considering lessons learned from past laparoscopic training, a standardized national robotic training program for colon and rectal surgery residents was developed and implemented in 2011...

BACKGROUND AND OBJECTIVE: The pullout strength of a screw is an indicator of how secure bone fragments are being held in place. Such bone-purchasing ability is sensitive to bone quality, thread design, and the pilot hole, and is often evaluated by experimental and numerical methods. Historically, there are some mathematical formulae to simulate the screw withdrawal from the synthetic bone. There are great variations in screw specifications. However, extensive investigation of the correlation between experimental and analytical results has not been reported in literature...

BACKGROUND: Prior work has described 5 domains within the 22-item Sino-Nasal Outcomes Test (SNOT-22) that allow for stratification of symptoms into similar clusters and that can be used to direct therapy. Although the outcomes of various interventions on these symptom domains have been reported, minimal clinically important difference (MCID) values have not been investigated, which has limited clinical interpretation of these results. METHODS: This study was designed as a secondary analysis of a prospective, multi-institutional, observational cohort...

SIGNIFICANCE: The accommodative response is more affected by the type of refractive error than the method of stimulation, field of view (FOV), or stimulus depth. PURPOSE: This study aims to analyze the effect of stimulation method, stimulus depth, and FOV on the accommodation response (AR) for emmetropes (EMM), late-onset myopes (LOM), and early-onset myopes (EOM). METHODS: Monocular AR was measured in 26 young observers (n = 9 EMM, n = 8 LOM, n = 9 EOM) under 60 different viewing conditions that were the result of permuting the following factors: (1) stimulation method (free space or Badal lens viewing), (2) stimulus depth (flat or volumetric), (3) FOV (2...

Importance: Dissatisfaction with medical malpractice litigation has stimulated interest by health care organizations in developing alternatives to meet patients' needs after medical injury. In communication-and-resolution programs (CRPs), hospitals and liability insurers communicate with patients about adverse events, use investigation findings to improve patient safety, and offer compensation when substandard care caused harm. Despite increasing interest in this approach, little is known about patients' and family members' experiences with CRPs...

J Ensor, J J Deeks, E C Martin, R D Riley
INTRODUCTION: For tests reporting continuous results, primary studies usually provide test performance at multiple but often different thresholds. This creates missing data when performing a meta-analysis at each threshold. A standard meta-analysis (NI: No Imputation) ignores such missing data. A Single Imputation (SI) approach was recently proposed to recover missing threshold results. Here, we propose a new method (MIDC) that performs Multiple Imputation of the missing threshold results using Discrete Combinations...

REVIEW
Roberta Ara, Donna Rowen, Clara Mukuria
Mapping functions are estimated using regression analyses and are frequently used to predict health state utility values (HSUVs) in decision analytic models. Mapping functions are used when evidence on the required preference-based measure (PBM) is not available, or where modelled values are required for a decision analytic model, for example to control for important sociodemographic variables (such as age or gender). This article provides an overview of the latest recommendations including pre-mapping considerations, the mapping process including data requirements for undertaking the estimation of mapping functions, regression models for estimating mapping functions, assessing performance and reporting standards for mapping studies...

BACKGROUND: Analysis of safety reports has been utilized to guide practice improvement efforts in adult magnetic resonance imaging (MRI). Data specific to pediatric MRI could help target areas of improvement in this population. OBJECTIVE: To estimate the incidence of safety reports in pediatric MRI and to determine associated risk factors. MATERIALS AND METHODS: In a retrospective HIPAA-compliant, institutional review board-approved study, a single-institution Radiology Information System was queried to identify MRI studies performed in pediatric patients (0-18 years old) from 1/1/2010 to 12/31/2015...

Although research has demonstrated improved outcomes for outpatients who receive peer support-such as through online health communities, support groups, and mentoring systems-hospitalized patients have few mechanisms to receive such valuable support. To explore the opportunities for a hospital-based peer support system, we administered a survey to 146 pediatric patients and caregivers, and conducted semi-structured interviews with twelve patients and three caregivers in a children's hospital. Our analysis revealed that hospitalized individuals need peer support for five key purposes: (1) to ask about medical details-such as procedures, treatments, and medications; (2) to learn about healthcare providers; (3) to report and prevent medical errors; (4) to exchange emotional support; and (5) to manage their time in the hospital...

Children with traumatic brain injury are reported to have deficits in performance monitoring, but the mechanisms underlying these deficits are not well understood. Four performance monitoring hypotheses were explored by comparing how 28 children with traumatic brain injury and 28 typically developing controls (matched by age and sex) performed on the stop-signal task. Control children slowed significantly more following incorrect than correct stop-signal trials, fitting the error monitoring hypothesis. In contrast, the traumatic brain injury group showed no performance monitoring difference with trial types, but significant group differences did not emerge, suggesting that children with traumatic brain injury may not perform the same way as controls...

Arboviruses continue to pose serious public health threats in the World Health Organization (WHO) Western Pacific Region. As such, laboratories need to be equipped for their accurate detection. In 2011, to ensure test proficiency, the WHO Regional Office for the Western Pacific piloted an external quality assessment (EQA) programme for arbovirus diagnostics. By 2016, it had grown into a global programme with participation of 96 laboratories worldwide, including 25 laboratories from 19 countries, territories and areas in the Region...

Furan fatty acids are found in plants, algae, and fish, and reported to have some positive health benefits, including anti-oxidant and anti-inflammatory activities, and inhibition of non-enzymatic lipid peroxidation. A major metabolite of furan fatty acids, 3-carboxy-4-methyl-5-propyl-2-furanpropanoic acid (CMPF), has been reported to be increased in patients who progress from prediabetes to type 2 diabetes, although CMPF is not necessarily associated with impaired glucose metabolism. Other studies report that CMPF levels are lower in subjects with diabetes than control subjects...

BACKGROUND: Recent studies on the variants in duplicated human alpha globin genes (HBA2 and HBA1) actively target the α-globin gene as molecular modulators for the treatment of β-thalassemia major. Identification of the exact position of variant in HBA1, HBA2 or its patchworks is mandatory to support the therapeutic aims in β-thalassemia major, by identifying specific modulators for the reactivation of fetal hemoglobin production. Hence, accurate identification of the variants in α-globin genes is crucial for the proper diagnosis, treatment and genetic counseling...

A confocal laser displacement sensor using a micro-machined varifocal mirror is reported. The focal length modulation is a key function of the confocal sensor. The mechanism of the focal length modulation determines the measurement speed and range. Here, we propose application of the micro-machined varifocal mirror for the modulation. The varifocal mirror can realize faster modulation, small size, and low energy consumption for the confocal displacement sensor. The electrostatically actuated varifocal mirror made by single crystalline silicon is used...

Accurate measurements of visibility are of great importance in many fields. This paper reports a multipoint visibility measurement (MVM) method to measure and calculate the atmospheric transmittance, extinction coefficient, and meteorological optical range (MOR). The relative errors of atmospheric transmittance and MOR measured by the MVM method and traditional transmissometer method are analyzed and compared. Experiments were conducted indoors, and the data were simultaneously processed. The results revealed that the MVM can effectively improve the accuracy under different visibility conditions...

Benefiting from close to ideal amplification properties (high gain, low dark current, and low excess noise factor), HgCdTe electron initiated avalanche photodiode (e-APD) technology exhibits state of the art sensitivity, thus being especially relevant for applications relying on low light level detection, such as LIDAR (Light Detection And Ranging). In addition, the tunable gap of the Hg1-xCdxTe alloy enables coverage of the short wavelength infrared (SWIR) and especially the 2 μm spectral range. For these two reasons, a HgCdTe e-APD based detector is a promising candidate for future differential absorption LIDAR missions targeting greenhouse gas absorption bands in SWIR...

Spatial frequency domain imaging (SFDI), as a rapid, noncontact, and scan-free method, can realize wide-field, quantitative optical property mapping and tomographic imaging for a biological sample. Phase-measuring profilometry (PMP) is a surface profile characterization method. Since the projection of structured light onto an object is the basis for PMP and SFDI, the SFDI system is capable of performing both techniques. In this work, we present the results of a feasibility study with the developed SFDI system to realize acquisition of the optical property information and the surface profile information...
