ABSTRACTA long-term radio frequency interference monitoring program is now in progress at the Ohio State University Radio Observatory. Current observations encompass the 1-2 GHz band, measuring the signal strength in each 150 KHz subband. Preliminary results show many strong and persistent signals, and wide bands in which no signals are detected. Daily and weekly variations appear to be correlated with periods of maximum human activity such as “rush hours”. It may be that aircraft reflections are causing many of the signals to be received, and that airline schedules correlate with “rush hours”. The program is being upgraded to automatically measure the direction of arrival of each signal, as an aid to further identify it. This directional information will also be used in designing rolled edges and side shields for the co-located OSU Radio Telescope, to further reduce its vulnerability to RFI.

Abstract Objectives Attention-deficit/hyperactivity disorder (ADHD) is a neuropsychiatric disorder commonly diagnosed in childhood. Current pharmaceutical treatment options provide a poor long-term risk: benefit ratio with little knowledge of the long-term effects. A broad-spectrum multi-nutrient formula has shown promise in children, but its effects on nutrient status and the underlying metabolome interactions have not been characterized. Methods Blood samples from medication-free children (n = 74) with ADHD enrolled in a double–blind randomized placebo-controlled multinutrient trial (RCT) were collected at baseline and 8 weeks post-intervention. Following RCT is an 8-week open label phase during which all participants took the active supplement. Symptoms were assessed using the Child and Adolescent Symptom Inventory 5. Double-blinded plasma samples will be analyzed for tyrosine, phenylalanine, tryptophan, magnesium, and zinc. Untargeted LC-MS metabolomics using HILIC chromatography and a high resolution QTof will assess very polar analytes in plasma extracts. Linear modeling will elucidate the influence of treatment, sampling time, and ADHD symptom score on plasma nutrient and plasma metabolite concentration. Results Preliminary findings of the open label phase show a significant improvement in inattention (P = 0.0435), hyperactivity (P = 0.0068), ODD (P = 0.0108) and DMDD (P = 0.0119). We hypothesize that these improvements in ADHD symptoms will be correlated with increased circulating concentrations of tyrosine, phenylalanine, tryptophan, magnesium, zinc, and metabolites involved in neurotransmitter synthesis and/or branched chain amino acid metabolism. Conclusions Preliminary findings indicate improvements of ADHD symptoms of inattention, hyperactivity, ODD and DMDD following 8 weeks of open label multi-nutrient supplementation. Results of the double-blinded phase are expected to mirror those observed in the open label phase, with increases in nutrients in those receiving the multinutrient.

Use of nanoscale devices is helping to revolutionize medical treatment and research. The Ohio State University recently became the first place in the country where coronary bypass and mitral valve repair operations are performed by a computer controlled robot, operated by a remotely located surgeon handling joysticks and considering a three-dimensional, enlarged view of the surgical field. With the invaluable help of many associates and students, researchers have focused on two classes of objects: devices that feature nanopore membranes, and multifunctional particulates for the delivery of medical therapeutic agents. Nanomembranes may also be used as flux regulators for the long-term release of biopharmaceuticals from implanted depots. This application embodies a purely passive mass transport mode of molecules in channels that are just a few nanometers larger than the effective radii of the molecules themselves.

iTTP survivors experience high rates of adverse health sequelae and increased mortality over long-term follow up. We conducted this multi-center cohort study to evaluate long-term mortality and causes of death in iTTP survivors. Between 2003 and 2020, 222 patients were enrolled in the Ohio State University and Johns Hopkins TTP registries and followed for a median of 4.5 (interquartile range [IQR],75 0.4-11.5) years. Nine patients died during their first iTTP episode and 29 patients died during follow-up. Mortality rate was 1.8 times higher than expected from an age, sex and race adjusted reference population. Cardiovascular disease was a leading primary cause of death (27.6%) tied with relapsed iTTP (27.6%), followed by malignancy (20.7%), infection (13.8%), and other causes (10.3%). Male sex [HR 3.74 (95% CI 1.65-8.48, P=0.002), increasing age [HR 1.04 (95% CI 1.01-1.07), P=0.011] and number of iTTP episodes [HR 1.10 (95% CI 1.01-1.20), P=0.022] were associated with mortality in a model adjusted for African American race [HR 0.70 (95% CI 0.30-1.65), P=0.702], hypertension [HR 0.47 (95% CI 0.20-1.08), P=0.076], CKD [HR 1.46 (95% CI 0.65-3.30, P=0.358] and site [HR 1.46 (95% CI 0.64-3.30), P=0.358]. There was a trend towards shorter survival in patients with lower ADAMTS13 activity during remission (P=0.078). In conclusion, iTTP survivors are at higher risk of death compared with a reference population and cardiovascular disease is a leading cause of death. Our study highlights the need for survivorship care, and investigation focused on cardiovascular disease and early mortality in TTP survivors.

Background Suppression is associated with binocular vision conditions such as amblyopia and strabismus. Commercial methods of testing fusion often only measure central fusion or suppression at near. The purpose of this pilot study was to assess a new iPad picture fusion test that assesses foveal and central fusion at near. Methods Participants aged 5 years and older presenting for eye examination at The Ohio State University College of Optometry were enrolled. Results from visual acuity, dry and wet refraction/retinoscopy, stereopsis and cover testing were recorded from the patient chart. The iPad picture fusion test, Worth four-dot, Worth type test with foveal letter targets, and Polarized four-dot were performed by one examiner in a randomized order at 40 cm. Testing was repeated with the anaglyphic filters reversed. Crosstabulation and McNemar chi-square analysis were used to compare the results between fusion testing devices. Results Of the fifty participants (mean age = 17.5), twelve reported suppression and one reported diplopia. Testability was excellent for all tests (98% to 100%). There were no significant differences between tests in reported results (P ≥ 0.22 for all comparisons). No difference in reported fusion or suppression status was observed with change in orientation of the anaglyphic filters. Six participants reported foveal suppression alone at near which was not identified with Worth four-dot at near. Conclusion The iPad picture fusion test provided excellent testability and agreement with commonly used tests of fusion and allowed testing of both central and foveal fusion at near. Nearly half (46%) of participants with suppression reported foveal suppression, supporting the importance of testing for foveal suppression.
