Authors: Smith Jordan , Klug Robert , Dagg Thomas , Lewis Elizabeth , Cleland Paul , Porter Andrew , Ofei-Dodoo Samuel 
Published: March 2022

Introduction. The COVID-19 pandemic caused a pause to nearly all sporting activities in the spring of 2020, and collegiate athletes at the National Collegiate Athletic Association (NCAA)-affiliated universities whose sporting seasons were affected by the pandemic were granted an extra year of athletic eligibility. The study was conducted to determine how collegiate athletes planned to use an additional year of eligibility granted by the NCAA.
Methods. The authors conducted a cross-sectional survey of 632 athletes from two universities in the Midwestern United States, between August and September 2021. The athletes completed an anonymous, 9-item survey to assess the effect of the pandemic on athletic season, athletic eligibility, and potential change in an academic or professional career. Chi-square tests, generalized linear mixed models, and adjusted odds ratio were used for the analyses.
Results. The participation rate was 74.5% (471 of 632). Nearly 63% (290 of 461) of the athletes received an additional year of eligibility because of the pandemic, with 193 (66.6%) planned to use their extra year for scholastic development. Male athletes (65.3% vs 34.7%; χ2[1, n=290]=11.66, P<.001, Φ=0.20), Division II athletes (59.6% vs 40.4%; χ2[1, n=290]=13.93, P<.001, Φ=0.22), and athletes who had not previously used redshirt (73.1% vs 26.9%; χ2[1, n=290] = 4.79, P=.029, Φ=0.32) where more likely to use their extra year of eligibility academically.
Conclusions. Our findings suggest that most of the athletes planned to use their extra year of eligibility to pursue further scholastic or professional development, highlighting the positive part of the COVID-19 pandemic. Future studies should investigate how these findings relate to athletes from universities in different geographical locations, intra-division schools.

Malignancy is one of the major public health problems in Bosnia and Herzegovina. Along with breakthroughs in specific oncological therapy, improving the quality of life of cancer patients and management of therapy-induced side effects need to be recognized as a priority in the comprehensive cancer patient care. Fertility loss after cancer treatment is a field requiring special attention due to its various consequences on patients themselves. Although oncofertility is well-recognized area of oncology, low- to middle-income countries are facing issues with its implementation in everyday practice. Increased awareness about fertility preservation is of high priority for all specialists who participate in the medical care of cancer patients. The absence of a systemic solution and lack of expertise led to the founding of Fertility Preservation Working Group of the Oncology Association of Bosnia and Herzegovina. We have made recommendationsas an expert consensus with the ultimate goal of making the first step towards enhancement of oncofertility implementation in Bosnia and Herzegovina.
Ridicule, Humour and Anti-Roma Racism in Romanian Television News: A Multimodal Critical Discourse Analysis
Authors: Breazu Petre 
Published: March 2022

Research shows that the public image of Roma on television reinforces existing prejudice and stereotypes in relation to illiteracy, criminality, primitiveness, or refusal to comply with societal norms and values. Scholars have drawn attention to the various forms of racism, both overt and covert, we find in media and political discourse. Yet, one aspect that is less explored is the role of humor and ridicule in communicating anti-Roma racism. In this article, I conduct a multimodal critical discourse analysis (MCDA) of two news clips aired by one of the leading audio-visual stations in Romania. I draw attention to the use of humor and ridicule on public television as discursive strategies to belittle or conceal anti-Roma racism. I argue that such representations­—where buffoonery, bad taste, cultural incompetence, and arrogance are highlighted—go beyond simple entertainment and cheap laughs but reinforce the inferior and marginalised status that Romani people have held for centuries on Romanian territories.
On Delta Sets Of Some Pseudo-Symmetric Numerical Semigroups With Embedding Dimension Three
Authors: SÜER Meral , ÇELİK Özkan 
Published: March 2022

Let S be a numerical semigroup. The catenary degree of an element s in S is a non-negative integer used to measure the distance between factorizations of s. The catenary degree of the numerical semigroup S is obtained at the maximum catenary degree of its elements. The maximum catenary degree of S is attained via Betti elements of S with complex properties. The Betti elements of S can be obtained from all minimal presentations of S. A presentation for S is a system of generators of the kernel congruence of the special factorization homomorphism. A presentation is minimal if it can not be converted to another presentation, that is, any of its proper subsets is no longer a presentation. The Delta set of S is a factorization invariant measuring the complexity of sets of the factorization lengths for the elements in S.
In this study, we will mainly express the given above invariants of a special pseudo-symmetric numerical semigroup family in terms of its generators.
Adjoint Tomography of Northeast Japan Revealed by Common-Source Double-Difference Travel-Time Data

Published: March 2022

AbstractWe present the wave equation-based adjoint tomography of northeastern Japan using common-source double-difference travel-time data. More than 30,000 high-quality first P-wave arrivals from 117 local earthquakes recorded by 713 seismic stations are included in the inversion, generating more than 350,000 double-difference travel times of first P-wave arrivals. In comparison with commonly used travel-time data, the common-source double-difference travel times are insensitive to source parameters and source-side structures but place enhanced constraints on receiver-side structures. As a result, these robust double-difference travel times generate a reliable VP model down to a depth of 120 km. Our inversion results clearly show crustal low-velocity anomalies beneath the volcanic arc. The subducting Pacific slab is illuminated as a landward-dipping high-velocity anomaly, and the arc magmatism in the mantle wedge is shown as low-velocity anomalies. Thanks to the newly operated Seafloor Observation Network (S-net), prominent high-velocity bodies are detected in the fore-arc mantle wedge at depths of 30–60 km. These abnormal high-VP bodies indicate a low degree of serpentinization in the fore-arc mantle wedge at low temperatures, correlating well with the previous finding that the uppermost mantle in the Kuril and Tohoku fore-arc is cold and dry. Our inversion results reveal reliable tectonic features in the subduction zone beneath northeastern Japan, suggesting that wave equation-based common-source double-difference travel-time adjoint tomography is an effective and robust method to illuminate detailed structures of the crust and uppermost mantle.

En contextos mineros, como el de Segovia y Remedios, caracterizados por la alta migración de personas y la confluencia de múltiples actores y de diversos intereses, también existe una comunidad que hace frente a las consecuencias adversas de comportamientos afines a una cultura de la ilegalidad. En el estudio de ello, se encontró que la confianza influye en la acción colectiva y, esta última, constituye un insumo para considerar y conciliar problemas asociados a la cultura de la ilegalidad en contextos mineros. Lo anterior, se afirma, puede servir como insumo para la construcción de redes que propicien la acción colectiva, siendo esta protagonista de decisiones públicas y detonante de cambios sociales.

Abstract
Background. The specific organ microenvironment can promote the colonization of tumor cells. However, lack of research shed light on the liver microenvironment in synchronous liver metastasis in patients with gastric cancer (synGCLM). With the epidemic of HBV infection in China, we aim to explore the influence of hepatitis B surface antigen (HBsAg) on the risk of synGCLM.Methods. It was a cross-sectional study that enrolled 858 cases of newly diagnosed GC. The inclusion criteria were as follows: 1) Newly diagnosis GC by pathological reports of gastroscopic biopsy or surgical specimen; 2) No surgery, chemotherapy or other treatments were given in other hospitals before admission; 3) SynGCLM confirmed by biopsy or imaging evaluation reported by two senior radiologists, and complete imaging examination to detect other distant organ metastases; 4) Complete medical records including demographic information, tumor characteristics, HBV serologic assay and other clinical factors. HBsAg-positive was defined as the detection of serum HBsAg more than 10 IU/mL. The prevalence of synGCLM was compared between patients with HBsAg (HBsAg+) and those without HBsAg (HBsAg-). The risk factors for synGCLM were analyzed by univariate and multivariate logistic regression analyses. Especially in the HBsAg+ GC patients, aspartate aminotransferase to platelet ratio index (APRI), liver fibrosis-4 index (FIB-4) levels and hepatitis B e antigen (HBeAg) status were further analyzed.Results. The prevalence of synGCLM of the HBsAg+ group was 16.7%, higher compared to 7.0% of the HBsAg- group, which was of statistical significance (p = 0.014). Multivariate logistic regression analysis demonstrated that HBsAg (OR = 3.359, p = 0.008), the elevated level of carcinoembryonic antigen (CEA) (OR = 3.775, p < 0.001), alpha-fetoprotein (AFP) (OR = 6.204, p < 0.001), γ-glutamyltransferase (GGT) (OR = 5.081, p < 0.001), alkaline phosphatase (ALP) (OR = 3.968, p = 0.002) and age (OR = 1.028, p = 0.033) were risk factors for synGCLM. Among the HBsAg+ patients, both ARPI and FIB-4 were statistically higher in the patients with synGCLM (synGCLM+) compared to those without synGCLM (synGCLM-) (ARPI: p = 0.045; FIB-4: p = 0.047); HBeAg positivity was detected in 20.0% of synGCLM+ patients compared to 6.0% of synGCLM- patients, but the difference was of no significance (p = 0.190).Conclusions. HBV infection is a risk factor for synGCLM whereas elevated ARPI and FIB-4 may be pro-metastatic especially among the HBsAg+ GC patients. Age, preoperative CEA, AFP, GGT and ALP levels are associated with increased risk of synGCLM.

Abstract
Organic light-emitting devices (OLEDs) emissive in short-wavelength infrared (SWIR) region are attractive for ground-breaking applications in biosensors, biomedical imaging and next-generation optoelectronic devices. However, fabrication of such devices with high radiance has not yet been achieved, owing to an intrinsic limitation imposed by the energy-gap law, which leads to extremely low emission efficiency. Here we report that acceptor-donor-acceptor (A-D-A) type molecules with high co-planarity, rigidity of π-conjugated backbones, extremely small reorganization energy and electron-phonon coupling factor are capable of simultaneously providing strongly suppressed non-radiative recombination rate, and high operation stability at high current density. We achieve electrically driven SWIR with irradiance of 3.9 mW cm^-2 (corresponding to 7% of direct sunlight infrared irradiance), which is the brightest emission to date and surpasses that of any previously reported SWIR OLEDs sixty-fold. These findings should open a wide avenue to a new class of organic SWIR light sources for broad applications.

Abstract
Aim
Systemic sclerosis (SSc) is a rare autoimmune disorder characterized by vascular and fibrosing involvement of the skin and internal organs. In this study we determined the prevalence and characteristics of radiological hands and feet involvements in Iranian SSc patients identified disease–phenotype associations.
Methods
43 SSc patients (41 women and 2 men), with a median age of 44.79 years (ranges 26 to 70 years) and a mean disease duration of 11.78 years (ranges 2 to 28 years) were studied in this cross-sectional study.
Results
42 patients had radiological changes both in hands and feet. Only one patient had changes just in hand. The most frequent changes that we found in hand was Juxta-articular Osteoporosis (93%), Acro-osteolysis (58.2%), Joint Space Narrowing (55.8%). The prevalence of joint space narrowing or acro-osteolysis were higher in subjects with active skin involvement (modified Rodnan skin score (mRSS) > 14) (16/21 v 4/16 for patients with inactive skin involvement (mRSS < 14); p = 0.002). The most frequent changes that we found in foot were Juxta-articular Osteoporosis (93%), Acro-osteolysis (46.5%), Joint Space Narrowing (58.1%), subluxation (44.2%). The presence of anti-ccp antibody was detected in 4 (9.3%), while positive rheumatoid factor was found in 13 (30.2%) of SSc patients.
Conclusion
This study corroborates that an arthropathy is common in SSc patients. The introduction of the specific radiological involvements of SSc needs to be confirmed by further studies. in order to define the appropriate prognosis and treatment of patients.

Published: March 2022

Abstract
Background
The standard procedure for the planning of transcatheter aortic valve replacement (TAVR) is the combination of echocardiography, coronary angiography and cardiovascular computed tomography (TAVR-CT) for the exact determination of the aortic valve dimensions, valve size and implantation route. However, up to 80% of the patients undergoing TAVR suffer from chronic renal insufficiency. Alternatives to reduce the need for iodinated contrast agents are desirable. Cardiac magnetic resonance (CMR) imaging recently has emerged as such an alternative. Therefore, we aim to investigate, for the first time, the non-inferiority of TAVR-CMR to TAVR-CT regarding efficacy and safety end-points
Methods
This is a prospective, randomized, open-label trial. It is planned to include 250 patients with symptomatic severe aortic stenosis scheduled for TAVR based on a local heart-team decision. Patients will be randomized in a 1:1 fashion to receive a predefined TAVR-CMR protocol or to receive a standard TAVR-CT protocol within two weeks after inclusion. Follow-up will be performed at hospital discharge after TAVR and after one and two years. The primary efficacy outcome is device implantation success at discharge. The secondary endpoints are a combined safety endpoint and a combined clinical efficacy endpoint at baseline and at one and two years, as well as a comparison of imaging procedure related variables. Endpoint definitions are based on the updated 2012 VARC-2 consensus document.
Discussion
TAVR-CMR might be an alternative to TAVR-CT for planning a TAVR procedure. If proven to be effective and safe, a broader application of TAVR-CMR might reduce the incidence of acute kidney injury after TAVR and thus improve outcomes.
Trial registration:
The trial is registered at ClinicalTrials.gov (NCT03831087). The results will be disseminated at scientific meetings and publication in peer-reviewed journals.

Published: March 2022

Abstract
Introduction: Linking payments to results is introduced as a mechanism for increasing accountability. To this end, a policy, called IR-PfP, was implemented in Iran in 2014 as one of the components of the country's Health Transformation Plan. Thus, the present study aimed to report on the steps of agenda setting, development and implementation of this policy.Methodology: The present qualitative study was conducted in 2018 through document analysis and interviews. As for data analysis, the content analysis method with a theory-based approach and MAXQDA10 software were applied.Findings: The results indicated that the Refined Multiple Streams Framework well described the implementation of the policy. The three streams of law enforcement (Politics), shortcomings of the ongoing program (NPS) (Problem) and Pay for Performance mechanism (Policy) were merged with the opening of the first opportunity window, and the second opportunity window led to the incorporation of the next five streams. Therefore, the policy stream was redefined, and the politics and problem streams were respectively strengthened by some events, which were the dominant streams. The program and process streams became very weak due to executive and time limitations.Conclusion: The policy stream followed the politics and problem streams. The multiplicity of opportunity windows was verified, and creation of an institution and two policy groups were the main factors in agenda setting. The combination of all these results, stress the importance of dynamic studying of Iran's health policies.
Participatory surveillance for COVID-19 trends detection in Brazil

Published: March 2022

Abstract
The ongoing COVID-19 pandemic has emphasized the necessity of a well-functioning surveillance system to detect and mitigate disease outbreaks. Traditional surveillance (TS) usually relies on healthcare providers and generally suffers from reporting lags that prevent immediate response plans. Participatory surveillance (PS), an innovative digital approach whereby individuals voluntarily monitor and report on their own health status via Web-based surveys, has emerged in the past decade to complement traditional data collections approaches. This study compares novel PS data on COVID-19 infection rates across nine Brazilian cities with official TS data to examine the opportunities and challenges of using the former, and the potential advantages of combining the two approaches. We find that high participation rates are key for PS data to adequately mirror TS infection rates. Where participation was high, we document a significant trend correlation between lagged PS data and TS infection rates, suggesting that the former could be used for early detection. In our data, forecasting models integrating both approaches increased accuracy up to 3% relative to a 14-day forecast horizon model based exclusively on TS data. Furthermore, we show that the PS data captures a population that significantly differs from the traditional observation. These results corroborate previous studies when it comes to the benefits of an integrated and comprehensive surveillance system, but also shed lights on its limitations, and on the need for additional research to improve future implementations of PS platforms.

Abstract
Background: Postpartum hemorrhage (PPH) is a major cause of maternal mortality (MM) worldwide and particularly in Côte d'Ivoire. The treatment of last resort remains hemostasis hysterectomy. The objective of this study was to document hemostasis hysterectomies in PPH in Côte d'Ivoire.Methods: We conducted a descriptive cross-sectional study in 51 health districts from 2013-2017 on parturients for whom a hemostasis hysterectomy had been performed.Results: the frequency of PPH was 4 per 100 deliveries, the delivery hemorrhage was the most frequent cause (65.39%). We recorded in 51 health districts that had complete emergency obstetric care (EmONC) 1796 cases of hemostasis hysterectomy out of 540,508 deliveries performed, i.e. 1 (one) hemostasis hysterectomy for 307 deliveries. The case fatality rate for PPH was 5.53%.Conclusion: The reduction of hemostasis hysterectomies requires the reduction of partum hemorrhage through the improvement of the implementation of EmONC and the use of new hemostasis techniques such as uterine balloon tamponade.
