Abstract

OBJECTIVES
The aim was to determine long-term outcomes over a decade after first rib resection (FRR) in patients with neurogenic thoracic outlet syndrome (NTOS). A secondary aim was to investigate correlation of residual rib stump with long-term symptoms.

METHODS
This ambispective cohort included patients who underwent transaxillary FRRs for NTOS between 1998 and 2007. Short-term outcomes at 3-month clinical follow-up were retrospectively collected from medical records. Patients who agreed to participate in the study were invited to a long-term clinical follow-up in 2019. Disabilities of Arm, Shoulder, and Hand Score and Cervical Brachial Symptom Questionnaire were used. A chest X-ray limited to a clavicular projection was taken, and the length of the residual first rib was measured.

RESULTS
Twenty patients {mean age 41.8 [standard deviation (SD): 10.3 years]} who underwent 27 FRRs participated in the study. The mean follow-up time was 14.9 (SD: 3.6) years. Excellent or good recovery was noted after 16 (59.3% of operated arms) operations in the short-term follow-up and 22 (81.5%) operations in the long-term follow-up. No reoperations were necessary for residual symptoms. The mean Cervical Brachial Symptom Questionnaire score was 26.7 (SD: 28.2) (maximum 120), and the Disabilities of Arm, Shoulder, and Hand Score was 21.1 (SD: 18.4) (maximum 100) points. Twenty-six patients (96.3%) had a noticeable residual first rib stump. The mean length of the residual first rib was 28.9 (SD: 9.5) mm. More than 30-mm rib stump did not indicate a worse long-term outcome.

CONCLUSIONS
This study showed good long-term outcome without symptom recurrence after FRR for NTOS. In most patients, after surgery, quality of life and ability to work improved. Residual rib stump length was not associated with the treatment outcome.

AbstractBackgroundMultisystem inflammatory syndrome in children (MIS-C) is a severe clinical phenotype of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection that remains poorly understood.MethodsHospitalized children &lt;18 years of age with suspected coronavirus disease 2019 (COVID-19) (N = 53) were recruited into a prospective cohort study; 32 had confirmed COVID-19, with 16 meeting the US Centers for Disease Control criteria for MIS-C. Differences in nasopharyngeal viral ribonucleic acid (RNA) levels, SARS-CoV-2 seropositivity, and cytokine/chemokine profiles were examined, including after adjustments for age and sex.ResultsThe median ages for those with and without MIS-C were 8.7 years (interquartile range [IQR], 5.5–13.9) and 2.2 years (IQR, 1.1–10.5), respectively (P = .18), and nasopharyngeal levels of SARS-CoV-2 RNA did not differ significantly between the 2 groups (median 63 848.25 copies/mL versus 307.1 copies/mL, P = .66); 75% of those with MIS-C were antibody positive compared with 44% without (P = .026). Levels of 14 of 37 cytokines/chemokines (interleukin [IL]-1RA, IL-2RA, IL-6, IL-8, tumor necrosis factor-α, IL-10, IL-15, IL-18, monocyte chemoattractant protein [MCP]-1, IP-10, macrophage-inflammatory protein [MIP]-1α, MCP-2, MIP-1β, eotaxin) were significantly higher in children with MIS-C compared to those without, irrespective of age or sex (false discovery rate &lt;0.05; P &lt; .05).ConclusionsThe distinct pattern of heightened cytokine/chemokine dysregulation observed with MIS-C, compared with acute COVID-19, occurs across the pediatric age spectrum and with similar levels of nasopharyngeal SARS-CoV-2 RNA.

Published: May 2021

Abstract

Background
The preparedness of healthcare institutes for the foreseen changes expected to arise through the implementation of E-Health is a significant turning point in determining its success. This should be evaluated through the awareness and readiness of healthcare workers to adopt E-Health technology to reduce health information technology failures.

Methods
This study investigated the relationship between the perceived attributes of innovation and E-Health adoption decisions of healthcare workers as part of a preimplementation process. Using a cross-sectional quantitative approach, the dimensions of the diffusion of innovation (DOI) theory were used to assess the E-Health readiness of 110 healthcare workers in a Mauritian specialized hospital.

Results
A strong inclination towards E-Health adoption was observed, where the prime stimulators were perceived as modernization of healthcare management (84.1%, ẋ=4.19), increased work efficiency through reduction of duplication (77.6%, ẋ=4.10) and faster generation of results (71.1%, ẋ=4.07). The findings of this study also validated the use of five DOI dimensions (i.e. relative advantage, compatibility, complexity, trialability and observability) in a predictability model (F(5, 101)=17.067, p&lt;0.001) towards E-Health adoption. A significant association between ‘adopter category’ and ‘willingness to recommend E-Health adoption’ (χ2(8)=74.89, p&lt;0.001) endorsed the fact that physicians and nursing managers have central roles within a social ecosystem to facilitate the diffusion of technology and influence the adoption of innovation.

Conclusion
This is the first study of its kind in Mauritius to successfully characterize each adopter's profile and demonstrate the applicability of the DOI framework to predict the diffusion rate of E-Health platforms, while also highlighting the importance of identifying key opinion leaders who can be primed by innovators regarding the benefits of E-Health platforms, thus ensuring non-disruptive evolutionary innovation in the Mauritian healthcare sector.

Published: May 2021

Abstract

Background
Anhydrous milk fat can be obtained in two forms, ghee and butter oil. These products are made by boiling butter at 110–120°C and melting butter at 60–80°C, respectively, to give them their distinct flavor. Ghee is the most popular fatty dairy product in India and Egypt. Lipid oxidation is a major cause of ghee and butter oil deterioration, affecting their flavor, color, and nutritional value. It has been suggested that natural antioxidants can be used, instead of synthetic antioxidants, to retard lipid oxidation.

Objective
Evaluation of the antioxidant potential of potato peel, fenugreek seed, and ginger rhizome extracts, to study their effect on reducing lipid oxidation, and to monitor changes of ghee and butter oil qualities during storage.

Method
Ethanol extracts from potato peel, fenugreek seeds, and ginger rhizomes were prepared. Total phenolic compounds of these extracts were determined and 500 and 1000 ppm of each of these extracts were added to either ghee or butter oil treatments.

Results
Acid values, peroxide values, and thiobarbituric acid values decreased with the addition of plant extracts to both ghee and butter oil, while they increased during the storage period. Adding 1000 ppm from each extract was more efficient than adding 500 ppm of the same extract.

Conclusions
Ginger rhizome extract was the most effective in reducing lipid oxidation. Ghee treatments were more stable than corresponding butter oil treatments against lipid oxidation.

Highlights
This study demonstrates the use of natural antioxidants, instead of synthetic antioxidants, in preserving ghee and butter oil
Identification of plastic constitutive Johnson–Cook model parameters by optimization-based inverse method
Authors: Jang Taek Jin , Kim Jong-Bong , Shin Hyunho 
Published: May 2021

Abstract
Because the design of most products incorporates numerical analysis such as the finite element method, these days, accurate determination of dynamic material model parameters is significant. Usually, the dynamic constitutive model parameters such as those in the Johnson–Cook (JC) model are determined by fitting stress–strain curves obtained by split Hopkins pressure bar (SHPB) tests at various strain rates and temperatures. However, the determination of model parameters by fitting cannot consider potential three-dimensional heterogeneities of stress propagation because the stress and strain are calculated with the assumption of one-dimensional wave propagation. In this study, to accurately determine plastic constitutive model parameters considering all of the potential heterogeneities of stress propagation, an optimization-based inverse method was proposed. Multiple objectives were defined with multiple experimental data that were obtained by SHPB tests at different conditions. The error was defined using transmitted and reflected bar signals obtained in experiments and finite element analysis with candidate model parameters. JC model parameters were set as design variables and determined to minimize the error. To show the reliability of the proposed method, experimental data were generated numerically by FE analysis with known model parameters. The parameters determined by the proposed method were compared with the known exact values. Model coefficients were also determined by fitting the stress–strain relations to show the superiority of the proposed method. Though the fitting of stress–strain curves can also reasonably determine the model coefficients, it was shown that the model parameters could be determined accurately by the proposed optimization-based inverse method.

AbstractUnderstanding how demographic parameters respond to climatic variables is essential for predicting species’ response to changing environmental conditions. The California pocket mouse (Chaetodipus californicus) is an inhabitant of coastal-central California oak (Quercus spp.) woodland that is undergoing a rapid anthropogenic transformation while also facing effects of global climate change. We analyzed the population dynamics of the California pocket mouse by applying Pradel’s temporal symmetry model to a 10-year (2004 – 2013) capture–mark–recapture data set to estimate survival and recruitment rates and realized population growth rate. The overall monthly apparent survival probability (ϕ) was 0.76 ± 0.01 SE and was slightly higher in the dry season (0.79 ± 0.02 SE) than the wet season (0.74 ± 0.01 SE). Coefficients of variation (CV) of temperature and rainfall (with and without a one-season lag), average seasonal temperature, and regional climatic variation (El Niño index) positively influenced ϕ. Overall monthly recruitment rate (f) was 0.17 ± 0.01 SE but varied seasonally; f was substantially higher during the dry season (0.39 ± 0.04 SE) than the wet season (0.09 ± 0.02 SE). Average seasonal temperature, CV of temperature and rainfall (without a one-season lag), and total seasonal rainfall (with a one-season lag) positively influenced recruitment, whereas regional climatic variation (El Niño index), total seasonal rainfall (without a one-season lag), and CV of rainfall (with a one-season lag) had a negative effect on f. Monthly realized population growth rate (λ) was 1.00 ± 0.02 SE for the entire study period, but it varied temporally. Our study provides the first estimates of demographic parameters for the California pocket mouse and tests for the influence of climatic variables on these parameters. Although the California pocket mouse population remained relatively stable during our study (as indicated by λ = 1.00), changing climate and anthropogenic influences on California oak woodland could adversely influence demographic parameters and population dynamics and might also indicate effects of climate change on its ecologically sensitive habitat.
Piloting a Climate-Change Adaptation Index on US National Forest Lands
Authors: Coughlan Michael R , Huber-Stearns Heidi , Schultz Courtney 
Published: May 2021

AbstractClimate change presents a novel and significant threat to the sustainability of forest ecosystems worldwide. The United States Forest Service (USFS) has conducted climate change vulnerability assessments for much of the 193 million acres of national forest lands it manages, yet little to no research exists on the degree to which management units have adopted considerations of climate change into planning or project implementation. In response to this knowledge gap, we piloted a survey instrument in USFS Region 1 (Northern region) and Region 6 (Pacific Northwest region) to determine criteria for assessing the degree to which national forests integrate climate-change considerations into their management planning and activities. Our resulting climate-change adaptation index provides an efficient quantitative approach for identifying where, how, and, potentially, why some national forests are making more progress toward incorporating climate-change adaptations into forest planning and management.
Accumulated Homelessness: Analysing Protracted Displacement along Eritreans’ Life Histories
Authors: Belloni Milena , Massa Aurora 
Published: May 2021

AbstractThis article introduces the notion of ‘accumulated homelessness’ to account for the repeated loss and lack of home experienced by many migrants in Europe today. Through the lens of home and homelessness, we argue that the debate on protracted displacement—often applied only to developing countries—should be extended to Europe. Going beyond the idea of shelterlessness, we consider homelessness as a multidimensional and multiscalar condition which encompasses material and emotional aspects. By analysing two life histories of Eritrean men living in Italy and in the Netherlands, we examine the set of structural, social, and individual conditions leading them to lose home in different places and times as well as their attempts—such as finding accommodation, establishing a community organisation, or moving onwards—to reconstruct home.
What Do Asylum Seekers Prioritise—Safety or Welfare Benefits? The Influence of Policies on Asylum Flows to the EU15 Countries
Authors: Diop-Christensen Anna , Diop Lanciné Eric 
Published: May 2021

AbstractFrom the beginning of the Arab Spring in 2010, Europe has experienced an increasing inflow of asylum seekers, which later peaked in 2015. While some governments sought national solutions and responded by tightening controls and rights for asylum seekers and refugees, others advocated for European burden sharing and a more humanistic response. This study investigates the extent to which asylum seekers respond to policy changes and prioritise between different policies. Further, than existing studies, we develop a theoretical framework for improving the understanding of what asylum seekers prioritise. Additionally, we also contribute empirically by using recent asylum application data for the EU15 countries (UNHCR data from 2008 to 2015) to disentangle the influence of single policy elements rather than focussing on asylum regimes or composite indexes as has been the case in previous research. Our results indicate that asylum seekers prioritise their short- to medium-term security by choosing destination countries with the most liberal refugee recognition and family reunification policies. In contrast, the level of social assistance accessible to refugees and the easiness of obtaining permanent resident status are unimportant.
Sexual Health among HIV-Negative Gay and Bisexual Men in Lebanon: A Comparison between Native and Immigrant/Refugee Communities
Authors: Maatouk Ismael , Assi Moubadda , Jaspal Rusi 
Published: May 2021

Abstract
Unlike native gay and bisexual male (GBM), immigrant/refugee GBM in Lebanon have an added vulnerability to poor sexual health. The objective was to compare sexual health variables between these two communities. GBM who are immigrants/refugees were more likely to report non-university level of education, heterosexual marriage, engagement in sex work, past diagnosis of syphilis, healthcare and employment stigma, lower STI knowledge, and a higher number of male sex partners. Being foreign and feeling sufficiently informed about STIs were indicators of STI knowledge. This study highlights the roles of education and immigrant/refugee status in STI knowledge in migrant GBM in Lebanon.
Examining Interviewers’ Ratings of Respondents’ Health: Does Location in the Survey Matter for Interviewers’ Evaluations of Respondents?
Authors: Garbarski Dana , Schaeffer Nora Cate , Dykema Jennifer 
Published: May 2021

Abstract
Interviewers’ ratings of survey respondents’ health (IRH) are a promising measure of health to include in surveys as a complementary measure to self-rated health. However, our understanding of the factors contributing to IRH remains incomplete. This is the first study to examine whether and how it matters when in the interview interviewers evaluate respondents’ health in a face-to-face survey, in an experiment embedded in the UK Innovation Panel Study. We find that interviewers are more likely to rate the respondent’s health as “excellent” when IRH is rated at the end of the interview compared to the beginning. Drawing from the continuum model of impression formation, we examined whether associations between IRH and relevant covariates vary depending on placement in interview. We find that across several characteristics of interviewers and respondents, only the number of interviews completed by interviewers varies by IRH assessment location in its effect on IRH. We also find evidence that interviewer variance is lower when IRH is assessed prior to compared to after the interview. Finally, the location of IRH assessment does not impact the concurrent or predictive validity of IRH. Overall, the results suggest that in a general population study with some health questions, there may be benefits to having interviewers rate respondents’ health at the beginning of the interview (rather than at the end as in prior research) in terms of lower interviewer variance, particularly in the absence of interviewer training that mitigates the impact of within-study experience on IRH assessments.
Photometric cross-calibration of the SDSS Stripe 82 Standard Stars catalogue with Gaia EDR3, and comparison with Pan-STARRS1, DES, CFIS, and GALEX catalogues

Published: May 2021

ABSTRACT
We extend the SDSS Stripe 82 Standard Stars catalogue with post-2007 SDSS imaging data. This improved version lists averaged SDSS ugriz photometry for nearly a million stars brighter than r ∼ 22 mag. With 2–3 times more measurements per star, random errors are 1.4–1.7 times smaller than in the original catalogue, and about three times smaller than for individual SDSS runs. Random errors in the new catalogue are $\lesssim$0.01 mag for stars brighter than 20.0, 21.0, 21.0, 20.5, and 19.0 mag in u, g, r, i, and z-bands, respectively. We achieve this error threshold by using the Gaia Early Data Release 3 (EDR3) Gmag photometry to derive grey photometric zeropoint corrections, as functions of RA and Declination, for the SDSS catalogue, and use the Gaia BP–RP colour to derive corrections in the ugiz bands, relative to the r-band. The quality of the recalibrated photometry, tested against Pan-STARRS1, DES, CFIS, and GALEX surveys, indicates spatial variations of photometric zeropoints ≦ 0.01 mag (rms), with typical values of 3–7 millimag in the RA, and 1–2 millimag in the Declination directions, except for $\lesssim$6 millimag scatter in the u-band. We also report a few minor photometric problems with other surveys considered here, including a magnitude-dependent ∼0.01 mag bias between 16 ≤ GGaia ≤ 20 in the Gaia EDR3. Our new, publicly available catalogue offers robust calibration of ugriz photometry below 1 per cent level, and will be helpful during the commissioning of the Vera C. Rubin Observatory Legacy Survey of Space and Time.
Accurate distances to Galactic globular clusters through a combination of Gaia EDR3, HST, and literature data
Authors: Baumgardt H , Vasiliev E 
Published: May 2021

ABSTRACT
We have derived accurate distances to Galactic globular clusters by combining data from the Gaia Early Data Release 3 (EDR3) with distances based on Hubble Space Telescope (HST) data and literature-based distances. We determine distances either directly from the Gaia EDR3 parallaxes, or kinematically by combining line-of-sight velocity dispersion profiles with Gaia EDR3 and HST-based proper motion velocity dispersion profiles. We furthermore calculate cluster distances from fitting nearby subdwarfs, whose absolute luminosities we determine from their Gaia EDR3 parallaxes, to globular cluster main sequences. We finally use HST-based stellar number counts to determine distances. We find good agreement in the average distances derived from the different methods down to a level of about 2 per cent. Combining all available data, we are able to derive distances to 162 Galactic globular clusters, with the distances to about 20 nearby globular clusters determined with an accuracy of 1 per cent or better. We finally discuss the implications of our distances for the value of the local Hubble constant.
