Food and Housing Insecurity Screening Practices among UNMH Pediatric Providers

Introduction: The American Academy of Pediatrics recommends food insecurity (FI) screening at all pediatric visits. Despite an existing EMR screening tool, how our pediatric providers screen FI and housing insecurity (HI) is unknown. Our objective was to collect formative data on FI and HI screening practices of UNMH pediatric providers to allow for the design of a quality improvement (QI) project. Methods: We performed a baseline cross-sectional survey with UNMH pediatric residents and attendings in May 2020. Results: Fifty-two individuals completed the survey (40.4% attendings, 59.6% residents). In inpatient settings, 67.8% of residents and 33.3% of attendings screen FI occasionally or only if pertinent to the chief complaint. For HI, 48.4% of residents and 33.3% of attendings screen occasionally or only if pertinent. In outpatient settings, 29.1% of residents and 5.3% of attendings screen FI occasionally or only if pertinent. For HI, 32.2% of residents and 15.8% of attendings screen occasionally or only if pertinent. When asked if they knew where to find the current EMR screening tool results, 61.3% of residents and 42.9% of attendings were unaware of the current screening tool. In terms of documentation, 58.1% of residents and 28.6% of attendings document FI occasionally or only if pertinent. For HI, 64.6% of residents and 28.6% of attendings document occasionally or only if pertinent. When asked where they document the screening, the “Social History” was the most commonly reported response for residents (83.3%) and “Assessment and Plan” for attendings (52.9%). Conclusion: We found that providers are unaware of current screening tools. Documentation practices are inconsistent. Based on these baseline results, our QI project will standardize the FI and HI screening and documentation practices in pediatric inpatient and outpatient settings

Functional Foreign Accent Syndrome in suspected Conversion Disorder: A case study

Background and objectives: We provide a case analysis for a 28-year-old, native Dutch-speaking lady who developed Foreign Accent Syndrome (FAS), a few weeks after falling down the staircase. In addition to FAS, which gave the impression she spoke with a German accent, German(-like) words and structures occurred. Speech symptoms were aggravated by increased stress, fatigue or emotional pressure, and this triggered jargon speech. It was hypothesized her FAS and jargon developed on a functional basis. Methods: An in-depth analysis of the patient's medical background, neuropsychological and neurolinguistic tests and psychodiagnostic exams were done. The patient participated in an fMRI experiment. In a syllable repetition paradigm, motor speech activations were compared to those of healthy individuals, to see whether they were altered, which would be expected in case of a neurological etiology. Results: Medical history disclosed prior traumatic experiences for which she sought help, but no neurological incidents. Repeated neuropsychological and neurolinguistic tests showed deficits in recent memory and executive functioning. The patient demonstrated great difficulties with picture naming. Clinically, language switching and mixing as well as recurring jargon speech was found. Formal psychodiagnostic tests did not identify a clear disorder, but psychodiagnostic interviews were consistent with a DSM-5 conversion disorder. The fMRI study demonstrated that speech network activations corresponded to those found in healthy participants. Conclusion: The clinical neurolinguistic characteristics, outcome of the fMRI experiment, together with the clinical psychodiagnostic findings were strongly indicative for an underlying functional etiology for the FAS and jargon speech, presenting as symptoms of conversion disorder

Experimental results from the ST7 mission on LISA Pathfinder

The Space Technology 7 Disturbance Reduction System (ST7-DRS) is a NASA technology demonstration payload that operated from January 2016 through July 2017 on the European Space Agency’s (ESA) LISA Pathfinder spacecraft. The joint goal of the NASA and ESA missions was to validate key technologies for a future space-based gravitational wave observatory targeting the source-rich millihertz band. The two primary components of ST7-DRS are a micropropulsion system based on colloidal micro-Newton thrusters (CMNTs) and a control system that simultaneously controls the attitude and position of the spacecraft and the two free-flying test masses (TMs). This paper presents our main experimental results and summarizes the overall performance of the CMNTs and control laws. We find the CMNT performance to be consistent with preflight predictions, with a measured system thrust noise on the order of 100  nN/√Hz in the 1  mHz≤f≤30  mHz band. The control system maintained the TM-spacecraft separation with an RMS error of less than 2 nm and a noise spectral density of less than 3  nm/√Hz in the same band. Thruster calibration measurements yield thrust values consistent with the performance model and ground-based thrust-stand measurements, to within a few percent. We also report a differential acceleration noise between the two test masses with a spectral density of roughly 3  fm/s2/√Hz in the 1  mHz≤f≤30  mHz band, slightly less than twice as large as the best performance reported with the baseline LISA Pathfinder configuration and below the current requirements for the Laser Interferometer Space Antenna mission

A torsional dilatometer for volume change measurements on deformed glasses: Instrument description and measurements on equilibrated glasses

An automated mercury dilatometer has been designed and built for the purpose of making volume change measurements on cylindrical samples subjected to torsional deformations. In its current configuration the instrument takes readings of torque, normal force, and volume change upon application of a twist at one end of the sample. Volume change sensitivity of approximately 2⨯10—cm makes possible relative volume change measurements of the order of ΔV/Vo≃10-7 given the sample geometry. Over long times temperature stability limits this to approximately 2.5⨯10“5. The instrument is described and preliminary measurements are presented for epoxy glasses which have been equilibrated by annealing near to the glass transition. The results show that the volume of the sample tested at temperatures ranging from 10 K below the conventionally measured glass transition temperature Tg to Tg increases upon application of a torsional deformation. This result is contrary to results reported in the literature for samples tested well below Tg. © 1990, The Society of Rheology. All rights reserved

Interfacial behavior of a reacting alkoxysilane monolayer system

We report here the results on the investigations of the dynamic interfacial behavior of a trifunctional alkoxysilane, octadecyltrimethoxysilane (OTMS) as it is reacting at the air-water interface. We have investigated both the II-A isotherms and A(t) isobars of OTMS at acidic subphases. An attempt to analyze the kinetics of the reaction in the monolayer was limited to the early stages of the reactions and only describes the kinetics of hydrolysis. We also confirmed by rheological measurements that this system does indeed form a network inefficiently and the resulting structure most likely consists of extensive linear segments as has been suggested in earlier reports. The general rheological characteristic indicates the product to have high molecular weight. The product also exhibited a 2D sol-gel transition that has general features of a percolating network. However, the scaling behavior does not follow exactly that predicted; several reasons for this are discussed. (Figure Presented) A(t) isobars of OTMS at various subphase pH

Polymerization of 2-Pentadecylaniline Monolayers at Fluid Surfaces: Kinetics, Thermodynamics, and Mechanism

Monolayers of 2-pentadecylaniline were polymerized at the air/aqueous acid interface using ammonium persulfate as the oxidizing agent. Isotherms of 2-pentadecylaniline were measured on a 0.1 M sulfuric acid subphase at different temperatures. The mean molecular area at the surface pressure onset was found to increase with temperature. The effect of varying the applied surface pressure and temperature on the polymerization rate of 2-pentadecylaniline at the interface was investigated. Activation energy and other thermodynamic parameters such as enthalpy, entropy, and Gibbs free energy of activation were calculated. The activation energy increased with increasing applied surface pressure. This result was interpreted in terms of intermolecular distances. The polymerization rate at the interface also increased with increasing applied surface pressure at a given temperature. Such experiments allowed the measurement of the activation area at a given temperature. The results cited above are used in interpreting the polymerization mechanism. © 1993, American Chemical Society. All rights reserved
