Abstract
Background: Adaptation, a form of modification that aims to improve an intervention’s acceptability and sustainability in a given context, is essential to successful implementation in some settings. Due to the COVID-19 pandemic, clinicians have rapidly adapted how they deliver patient care. PPE Portraits are a form of adaptation, whereby health workers affix a postcard size portrait of themselves to the front of their personal protective equipment (PPE) in order to foster human connection during COVID-19. Methods: We used the expanded framework for reporting adaptations and modifications to evidence-based interventions (FRAME) method to better understand the reasoning behind and results of each adaptation. Throughout multiple implementations across 25 institutions, we piloted, tracked and analyzed adaptations using FRAME and design thinking. For each adaptation, we assessed the stage of implementation, whether the change was planned, decision makers involved, level of delivery impacted, fidelity to original intervention, and the goal and reasoning for adaptation. We added three crucial components to the FRAME: original purpose of the adaptation, unintended consequences, and alternative adaptations.Results: When implementing PPE Portraits across settings, from a local assisted living center’s memory unit to a pediatric emergency department, several requests for adaptations arose during early development stages before implementation. Adaptations primarily related to 1) provider convenience and comfort, 2) patient populations, and 3) scale. Providers preferred smaller portraits and rounded (rather than square) laminated edges that could potentially injure a patient. Affixing the portrait with a magnet was rejected given the potential choking hazard the magnetic strip presented for children. Other adaptations related to ease of dissemination included slowing the process down during early development and providing buttons, which could be produced easily at scale. Conclusion: The FRAME was used to curate the reasoning for each adaptation and to inform future dissemination. We look forward to utilizing FRAME including our additions and design thinking, to build out a range of PPE Portrait best-practices with accompanying costs and benefits.

Abstract
Background Clinical trials are an essential source for advances in oncologic care, yet the enrollment rate is only 2-4%. Patients' reluctance to participate is an important barrier. This study evaluates patients' level of understanding and attitudes towards clinical trials.Methods Two-hundred patients receiving active anti-neoplastic therapy at a large tertiary hospital completed an anonymous questionnaire comprised of demographic information, past experience in clinical research and basic knowledge on clinical trials. Results The majority of respondents did not meet the minimum knowledge level criteria. The concerns of those who replied that they would decline to participate in a clinical trial were related to assignment to the placebo arm, provision of informed consent and trust issues with their oncologist. Those with adequate knowledge were significantly more interested in participating in. Patients with past experience in clinical trials had a higher level of academic education, were less religious, had a better understanding of medical research and were inclined to participate in future research.Conclusions Misperceptions of clinical trials may contribute substantially to the unwillingness to participate in them.Trial registration The study was approved by the Tel Aviv Sourasky Medical Center ethics committee (0565-14-TLV January 7th, 2015) and it was conducted in full accordance with the guidelines for Good Clinical Practice and the Declaration of Helsinki. Agreement to respond to the questionnaire was taken as formal consent to participate in this study.
Interpretation of FSC-Experiments Deviation
Authors: geilhaupt manfred 
Published: June 2021

Abstract
The Fine Structure Constant (FSC) discussion started 1916 with the definition of alpha by Sommerfeld (α=e^2/(2*h *c *εo)) which must be a constant number in so far as the elementary charge (e) is a constant. Morel et al. ( 2020) and Parker et al. (2018) presented the most accurate FSC from similar atomic (Rb and Cs) interferometric experiments recently. Surprisingly there is a „tension“ between their two values from an experimental point of view manifesting a theoretical problem due to a „running“ alpha-number indicating a „running“ elementary charge-value which should not be the case in Standard Physics. Here is our interpretation from the General Relativity (GR) point of view to come up with a constant alpha(0) within both experiments.Morel (Rb: 1/α(Rb) =137,035999206(11)) and Parker (Cs: 1/α(Cs) =137,035999046(27))

Published: June 2021

Abstract
Im/migrants are a vulnerable population who face numerous social barriers. These barriers likely contribute to unmet social needs, which may increase avoidable health care utilization such as emergency department (ED) visits. Within an im/migrant cohort at a large urban safety-net hospital (N = 1405 patients), we describe types and levels of unmet social needs, and estimate the relationship between level of unmet social needs and ED visit rates. Food insecurity was the most prevalent reported social need (30%), followed by educational needs (29%); employment needs (19%); barriers to paying for medications (18%); lack of transportation (17%); and housing insecurity (10%). After adjusting for sociodemographic factors, having ≥ 4 unmet social needs was associated with an additional 249.47 visits/1000 im/migrant patients/year (95% CI 15.95-482.99, p-value = 0.036), relative to those with no reported needs. Our findings emphasize the importance of rigorously assessing and addressing social needs within im/migrant populations, which may narrow disparities in ED use.

Published: May 2021

Purposeor research is to develop an algorithm for detecting obstacles on the orthophotomap based on the analysis of the spectral landscape indices in the tasks of mobile robotic equipment navigation in agricultural areas.Methods.The following landscape indices characterizing objects of various types on a map obtained by spectral aerial photography have been considered in the paper: normalized difference vegetation index (NDVI), normalized building difference index (NDBI), normalized difference water index (NDWI), and soil-adjusted vegetation index (SAVI). These indices provide an assessment of the four main classes of objects on the map: vegetation, buildings, water bodies, and soil cover. An algorithm that provides the segmentation of zones on the map which are impassable for ground robotic means using multispectral images and the considered indices was proposed.Results. Each image is presented in the form of a colour map based on the pixel-by-pixel calculation of the indicated indices. In this case, three indices, i.e. SAVI, NDWI, NDBI, are combined (superimposed on each other), and then the NDVI layer is subtracted from the resulting image to highlight the passable zones. Thus, a formula to obtain a mask of obstacles in the image was obtained. Hence, this algorithm allows generalizing the results of calculations for all selected indices and constructing a mask of obstacles in the image. For quantitative assessment the of the algorithm execution, the area of obstacles was calculated using the indices on a sample of manually marked images. The experiments conducted show that the developed algorithm provides, on average, detection of 85.47 % of the area of all impassable zones in the images in the above classes of land cover.Conclusion.An algorithm for the automated detection of obstacles on a map obtained from a spectral orthophotomap of the area for use in the tasks of mobile robotic equipment navigation in agricultural areas has been developed and tested. In the further research, to determine flat soil areas, it is planned to modify the developed solution using the improved modified soil-adjusted vegetation index (MSAVI).
