Policy implementation analysis on access to healthcare among undocumented immigrants in seven autonomous communities of Spain, 2012–2018
Authors: Gogishvili Megi , Costa Sergio A , Flórez Karen , Huang Terry T 
Published: June 2021

BackgroundIn 2012, the Government of Spain enacted Royal Decree-Law (RDL) 16/2012 and Royal Decree (RD) 1192/2012 excluding undocumented immigrants from publicly funded healthcare services. We conducted a policy implementation analysis to describe and evaluate the legal and regulatory actions taken at the autonomous community (AC) level after enactment of 2012 RDL and RD and their impact on access to general healthcare and HIV services among undocumented immigrants.MethodsWe reviewed documents published by the governments of seven ACs (Andalucía, Aragón, Euskadi (Basque Country), Castilla-La Mancha, Galicia, Madrid, Valencia) from April 2012 to July 2018, describing circumstances under which undocumented immigrants would be able to access free healthcare services. We developed indicators according to the main systemic barriers presented in official documents to analyse access to free healthcare across the participating ACs. ACs were grouped under five access categories: high, medium-high, medium, medium-low and low.ResultsAndalucía provided the highest access to free healthcare for undocumented immigrants in both general care and HIV treatment. Medium-high access was provided by Euskadi and medium access by Aragón, Madrid and Valencia. Castilla-La Mancha provided medium-low access. Galicia had low access. Only Madrid and Galicia provided different and higher level of access to undocumented migrants in HIV care compared with general healthcare.ConclusionsImplementation of 2012 RDL and RD across the ACs varied significantly, in part due to the decentralisation of the Spanish healthcare system. The challenge of healthcare access among undocumented immigrants included persistent systemic restrictions, frequent and unclear rule changes, and the need to navigate differences across ACs of Spain.

Published: June 2021

IntroductionWe will evaluate the feasibility of a randomised controlled trial to estimate the effectiveness and cost-effectiveness of a rehabilitation intervention on pain, function and health-related quality of life following neck dissection (ND) after head and neck cancer (HNC).Methods and analysisThis is a pragmatic, multicentred, feasibility study. Participants are randomised to usual care (control) or usual care plus an individualised, rehabilitation programme (Getting Recovery Right After Neck Dissection, GRRAND intervention). Adults aged over 18 with HNC for whom ND is part of their care will be recruited from specialist clinics. Participants are randomised in 1:1 ratio using a web-based service. The target sample size is 60 participants. Usual care will be received by all participants during their postoperative inpatient stay consisting standard National Health Service care supplemented with a booklet advising on postoperative self-management strategies. The GRRAND intervention programme consists of usual care plus up to six individual physiotherapy sessions including neck and shoulder range of motion (ROM) and progressive resistance exercises, advice and education. Between sessions participants will be advised to complete a home exercise programme. The primary outcome is to determine recruitment and retention rates from study participants across sites. Outcomes will be measured at 6 and 12 months. Participants and physiotherapists will be invited to an optional qualitative interview at the completion of their involvement in the study. The target qualitative sample size is 15 participants and 12 physiotherapists. Interviews aim to further investigate the feasibility and acceptability of the intervention and to determine wider experiences of the study design and intervention from patient and physiotherapist perspectives.Ethics and disseminationEthical approval was given on 29 October 2019 (National Research Ethics Committee Number: 19/SC/0457). Results will be reported at conferences and in peer-reviewed publications.Trial registration numberISRCTN11979997.StatusTrial recruitment is ongoing and is expected to be completed by 30 August 2021.

We obtain a system of highly non-linear differential equations, which consists of four differential equations with six unknown functions. To solve such a system, we assume a specific form of metric potentials, using the Krori–Barua ansatz. We successfully solve the system of differential equations, and we derive all the components of the energy–momentum tensor. Moreover, we derive the non-trivial general form of $${{\mathrm {f(R)}}}$$

Notably but rather expected, the exterior solution differs from the Schwarzschild one in the context of general relativity. The matching procedure will eventually relate two constants with the mass and radius of the compact stellar object. We list the necessary conditions that any compact anisotropic star must satisfy and explain in detail that our model bypasses all of these conditions for a special compact star $$\textit{Her X--1}$$

Variability of the low-level circulation of the South American Monsoon analysed with complex networks
Authors: Gelbrecht Maximilian , Boers Niklas , Kurths Jürgen 
Published: June 2021

AbstractUnderstanding the variability of low-level atmospheric circulation regimes is key for understanding the dynamics of monsoon systems. The South American Monsoon is characterized by strong year-long trade winds that are channeled southward into the South American Low-Level Jet after crossing the Amazon basin, which in turn is elementary for the moisture transport to Southern South America. In this study, we utilize streamflow wind networks, a type of climate networks that tracks the local flow of the wind field, together with the analysis of composites of wind, precipitation, and geopotential height fields, to investigate the variability of the South American low-level circulation. The streamflow wind networks are used here as they are able to directly track the wind flow and encode its spatiotemporal characteristics in their topology. We focus on intraseasonal variations in terms of active and break monsoon phases on the one hand, and on the interannual variability in terms of the impacts of the El Niño-Southern Oscillation on the other hand. Our findings highlight the importance of the South American Low-Level Jet, its spatial position and variability. Our study reveals the relation of the active and break regimes to anomalous high- and low-pressure systems over the southern Atlantic that are connected to Rossby wave trains from the southern Pacific, as well as the impact of these regimes on the cross-equatorial low-level flow. In addition, the streamflow networks that we use demonstrate significant shifts of the dominant wind flow pattern during El Niño and La Niña episodes.
Preservation of late Paleozoic glacial rock surfaces by burial prior to Cenozoic exhumation, Fleurieu Peninsula, Southeastern Australia
Authors: Holford Simon P. , Green Paul F. , Duddy Ian R. , Hillis Richard R. , Hill Steven M. , Stoker Martyn S. 
Published: June 2021

The antiquity of the Australian landscape has long been the subject of debate, with some studies inferring extraordinary longevity (>10
8
myr) for some subaerial landforms dating back to the early Paleozoic. A number of early Permian glacial erosion surfaces in the Fleurieu Peninsula, southeastern Australia, provide an opportunity to test the notion of long-term subaerial emergence, and thus tectonic and geomorphic stability, of parts of the Australian continent. Here we present results of apatite fission track analysis (AFTA) applied to a suite of samples collected from localities where glacial erosion features of early Permian age are developed. Our synthesis of AFTA results with geological data reveals four cooling episodes (C1-4), which are interpreted to represent distinct stages of exhumation. These episodes occurred during the Ediacaran to Ordovician (C1), mid-Carboniferous (C2), Permian to mid-Triassic (C3) and Eocene to Oligocene (C4).

The interpretation of AFTA results indicates that the Neoproterozoic
−
Lower Paleozoic metasedimentary rocks and granitic intrusions upon which the glacial rock surfaces generally occur were exhumed to the surface by the latest Carboniferous
−
earliest Permian during episodes C2 and/or C3, possibly as a far-field response to the intraplate Alice Springs Orogeny. The resulting landscapes were sculpted by glacial erosive processes. Our interpretation of AFTA results suggests that the erosion surfaces and overlying Permian sedimentary rocks were subsequently heated to between
c.
60 and 80°C, which we interpret as recording burial by a sedimentary cover comprising Permian and younger strata, roughly 1 km in thickness. This interpretation is consistent with existing thermochronological datasets from this region, and also with palynological and geochronological datasets from sediments in offshore Mesozoic
−
Cenozoic-age basins along the southern Australian margin that indicate substantial recycling of Permian
−
Cretaceous sediments. We propose that the exhumation which led to the contemporary exposure of the glacial erosion features began during the Eocene to Oligocene (episode C4), during the initial stages of intraplate deformation that has shaped the Mt Lofty and Flinders Ranges in South Australia. Our findings are consistent with several recent studies, which suggest that burial and exhumation have played a key role in the preservation and contemporary re-exposure of Gondwanan geomorphic features in the Australian landscape.
Epidemiology of Cardiopulmonary Resuscitation in Critically Ill Children Admitted to Pediatric Intensive Care Units Across England: A Multicenter Retrospective Cohort Study
Authors: Mustafa Khurram , Buckley Hannah , Feltbower Richard , Kumar Ramesh , Scholefield Barnaby R. 
Published: June 2021

Background
Cardiopulmonary arrests are a major contributor to mortality and morbidity in pediatric intensive care units (PICUs). Understanding the epidemiology and risk factors for CPR may inform national quality improvement initiatives.

Methods and Results
A retrospective cohort analysis using prospectively collected data from the Paediatric Intensive Care Audit Network database. The Paediatric Intensive Care Audit Network contains data on all PICU admissions in the United Kingdom. We identified children who received cardiopulmonary resuscitation (CPR) in 23 PICUs in England (2013–2017). Incidence rates of CPR and associated factors were analyzed. Logistic regression was used to estimate the size and precision of associations. Cumulative incidence of CPR was 2.2% for 68 114 admissions over 5 years with an incidence rate of 4.9 episodes/1000 bed days. Cardiovascular diagnosis (odds ratio [OR], 2.30; 95% CI, 2.02–2.61), age <1 year (OR, 1.84; 95% CI, 1.65–2.04), the Paediatric Index of Mortality 2 score on admission (OR, 1.045; 95% CI, 1.042–1.047) and longer length of stay (OR, 1.013; 95% CI, 1.012–1.014) were associated with increased odds of receiving CPR. We also found a higher risk of CPR associated with a history of preadmission cardiac arrest (OR, 20.69; [95% CI, 18.16–23.58) and for children with a cardiac condition admitted to a noncardiac PICU (OR, 2.75; 95% CI, 1.91–3.98). Children from Black (OR, 1.68; 95% CI, 1.36–2.07) and Asian (OR, 1.49; 95% CI, 1.28–1.74) racial/ethnic backgrounds were at higher risk of receiving CPR in PICU than White children.

Conclusions
Data from this first multicenter study from England provides a foundation for further research and evidence for benchmarking and quality improvement for prevention of cardiac arrests in PICU.
Common Forest, Private Timber: Managing the Commons in the Italian Alps
Authors: Bonan Giacomo , Lorenzini Claudio 
Published: June 2021

Abstract
The two key stakeholders in the commercial exploitation of the common woodlands in the eastern Italian Alps from the fifteenth to the eighteenth century were the mountain communities, which had ownership or right of use of the woodlands, and the timber merchants, who had the capital and skills to transform those woodlands into valuable commodities. A long-term perspective on the business of cutting, transporting, and marketing timber reveals the networks, strategic relationships, and complex socioeconomic conditions that emerged from the collaboration of local populations and outside interests in the timber trade for their mutual benefit.
Re-thinking the Tanẓīm: Tensions between Individual Identities and Organizational Structures in the Muslim Brotherhood after 2013
Authors: Ardovini Lucia 
Published: June 2021

Abstract
This article traces the struggle between individual agency and organizational structures characterizing the Muslim Brotherhood in the aftermath of the 2013 coup, identifying these tensions as a main point of contention driving its restructuring and fragmentation. Since Mohammed Morsi’s violent toppling, the Brotherhood experienced a process of gradual fragmentation, with tensions developing between different approaches to repression. Yet, while these debates came to the fore during the current crisis, they have roots in the pre-revolutionary period. The article traces the emergence of tensions between structure and agency from 2011 to the post-2013 context to provide a clearer picture of the internal challenges facing the Brotherhood today. It relies on data collected during fieldwork conducted between 2013 and 2019 in Turkey and the UK, and interviews with current and former Brotherhood members from across the organizational spectrum. It focuses on the members’ individual perspectives in order to trace the growing disconnect between them and the organization.
Major dietary patterns and metabolic syndrome associated with severity of coronary artery disease: A structural equation modeling
Authors: Kuhail Mohamed , Djafarian Kurosh , Shab-Bidar Sakineh , Yaseri Mehdi 
Published: June 2021

Background: The association of dietary patterns and metabolic syndrome with the severity of coronary artery disease (CAD) is little known. Aim: This study aimed to explore the relationship between major dietary patterns and the severity of CAD among newly discovered patients by using structural equation modeling (SEM). Methods: In this cross-sectional study, we included 423 newly diagnosed patients with CAD, aged 35–65 years, who underwent coronary angiography. The severity of CAD was assessed by the Gensini score. All patients were tested by using a semi-quantitative food frequency questionnaire, international physical activity questionnaire, perceived stress scale, lipid profile, fasting blood glucose, and anthropometric and blood pressure measurements. Statistical analysis was performed using SPSS and AMOS version 24. Results: Two dietary patterns (DPs) were identified by principal components analysis and labeled as “unhealthy DP” and “healthy DP”. The results of SEM analysis showed that the unhealthy DP has a significant positive direct association with the severity of CAD (β=0.304, p<0.001), which is indirectly mediated by the presence of metabolic syndrome (β=0.021, p=0.021), adjusted for age and perceived stress scale. However, healthy DP has a significant negative direct association with the Gensini score (β=-0.213, p<0.001), and an indirect association through negative metabolic syndrome (β=-0.019, p=0.022), controlled for gender, physical activity, and perceived stress scale. Conclusions: The severity of CAD was directly associated with the unhealthy DP and indirectly mediated by the presence of the metabolic syndrome, while a healthy DP had a direct inverse association with CAD severity and indirectly mediated by the absence of metabolic syndrome.

Published: June 2021

Background The Venablock© Venous Closure System (Invamed, Ankara, Turkey) is a novel cyanoacrylate-based non-thermal non-tumescent embolization device to block refluxing truncal veins for chronic venous insufficiency and varicose veins. The aim was to prospectively evaluate the safety and 6 months efficacy of Venablock© for the treatment of primary great saphenous vein (GSV) and small saphenous vein (SSV) incompetency in a multi-ethnic cohort from Singapore. Methods This was a single arm, single investigator prospective study of 29 patients (39 limbs, 39 truncal veins) recruited over a 5-month period (August 2019 to February 2020), who were treated with the Venablock© device at a tertiary vascular unit in Singapore. Patients with symptomatic varicose veins (C2–6) and had truncal reflux > 0.5 second on venous Duplex ultrasound were included. Follow-up occurred at 2 weeks, 3 and 6 months with dedicated quality of life questionnaires and a targeted Duplex ultrasound performed to check for continued venous occlusion. Result Mean age was 61.4 (±11.0) years and mean BMI was 26.2 (±5.7) kg/m2. 11/29 (37.9%) were males. Most common CEAP class treated was 2 (12/29, 41.3%). Mean diameter of treated GSV was 5.7 (±2.0) mm, 4.8 (±1.7) mm and 4.2 (±1.3) mm for the proximal, mid and distal above knee segments respectively. Mean time from access puncture to sheath removal was 23.4 (±10.0) mins. Vein occlusion at 2 weeks, 3 and 6 months was 39/39 (100%), 39/39 (100%) and 36/37 (97.2%) respectively. 5/29 (17.2%) developed puncture site infections, of which 3/29 (7.7%) required formal surgical drainage. 3/29 (7.7%) developed phlebitis. At 6 months, revised Venous Clinical Severity Score improved from 5.2 (±3.5) to 2.1 (±2.9; p < .001); EuroQol-5 Dimension score, from 7.4 (±2.1) to 5.7 (±1.4; p < .001); Aberdeen Varicose Vein Questionnaire score, from 18.1 (±15.5) to 7.9 (±8.9; p = .007); and Chronic Venous Insufficiency Questionnaire, from 18.6 (±16.2) to 4.5 (±6.3; p < .001). Conclusion Venablock© is a safe and efficacious option of treating truncal venous insufficiency in a multi-ethnic Asian cohort from Singapore in the short term. There is a significant improvement in QoL. Longer follow-up is required to assess the durability of this technique, in particular the higher puncture site infection rates observed compared to other glue-based therapies.

Authors: Luque-Tirado Andrea , Rodrigo-Herrero Silvia , Sánchez-Arjona María Bernal , Franco-Macías Emilio 
Published: June 2021

Objective: To first validate the diagnostic accuracy of the “Triana Test,” a new story recall test based on emotional material. Method: A phase I study of validation. We included 55 patients with amnestic Mild Cognitive Impairment and 69 healthy controls, diagnosed according to the “Memory Associative Test of the district of Seine-Saint-Denis” (TMA-93), and matched by age, gender, and educational level. The Triana Test’s diagnostic accuracy was calculated by ROC curve analysis and Spearman correlations estimated its convergent validity with a hippocampal memory test, the Free and Cued Selective Reminding Test with Immediate Recall (FCSRT+IR). Results: The “Triana Test” immediate and delayed recalls showed adequate diagnostic accuracy (AUC ≥ 0,74). The delayed free recall showed the highest diagnostic accuracy (AUC = 0.86). Correlations with the FCSRT+IR were moderate to strong. Conclusions: The “Triana Test” demonstrated accuracy for discriminating amnestic Mild Cognitive Impairment patients from healthy controls and convergent validity with the FCSRT+IR.
Analysis of the Quality of Prospective Randomized Controlled Trials for Treatment of Boxer’s Fractures
Authors: Patrick Cole M. , Fernandez Isaac , Gonzalez Gilberto A. , Nesti Leon J. , Dunn John C. 
Published: June 2021

Background This study aimed to review level I and II therapeutic studies on boxer’s fractures to measure variation in quality among the highest level study designs. Methods We used quantitative measures of study quality to evaluate prospective randomized controlled trials (RCTs) of treatments of boxer’s fractures. A search of PubMed, using terms “boxer’s fracture” and “fifth metacarpal neck fracture” identified 164 articles from 1961 to 2019. From this list, we identified 6 RCTs. Two observers classified each trial according to 3 systems: the Oxford Levels of Evidence, the modified Coleman Methodology Score, and the revised Consolidated Standards of Reporting Trials (CONSORT) score. Results The 2 reviewers were consistent in their use of the Oxford Levels of Evidence (100% agreement). The differences between the average modified Coleman Methodology scores and the average CONSORT scores assigned by the 2 observers were not significant (46.2 vs 45.3 points, κ = 0) and (13.7 vs 14.3 points, κ = 0.33), respectively. Both observers rated all the studies as level I and as unsatisfactory according to the Coleman Methodology Score (100% and 100%), and less than half as unsatisfactory according to the CONSORT score (50% and 17%). Areas of deficiency included randomization, blinding, group comparability, clinical effect measurements, and allocation into treatment arms. Conclusion Classifying orthopedic scientific reports according to the levels of evidence implies a degree of respect for level I and II studies that may not always be merited. Our data suggest that the quality of higher level studies, namely those involving boxer’s fractures, varies and may often be unsatisfactory when critically evaluated.
