Background
Plasma omega‐3 polyunsaturated fatty acids (ω3‐PUFAs) have been shown to be inversely correlated with the risk of cardiovascular death in primary prevention. The risk relationship in the setting of an acute coronary syndrome is less well established.

Methods and Results
Baseline plasma ω3‐PUFA composition (α‐linolenic acid, eicosapentaenoic acid, docosapentaenoic acid, and docosahexaenoic acid) was assessed through gas chromatography with flame ionization detection in a case‐cohort study involving 203 patients with cardiovascular death, 325 with myocardial infarction, 271 with ventricular tachycardia, and 161 with atrial fibrillation, and a random sample of 1612 event‐free subjects as controls from MERLIN‐TIMI 36 (Metabolic Efficiency With Ranolazine for Less Ischemia in Non–ST‐Elevation‐Acute Coronary Syndrome–Thrombolysis in Myocardial Infarction 36), a trial of patients hospitalized with non–ST‐segment–elevation ‐acute coronary syndrome. After inverse‐probability‐weighted multivariable adjustment including all traditional risk factors, a higher relative proportion of long‐chain ω3‐PUFAs (eicosapentaenoic acid, docosapentaenoic acid, docosahexaenoic acid) were associated with 18% lower odds of cardiovascular death (adjusted [adj] odds ratio [OR] per 1 SD, 0.82; 95% CI, 0.68–0.98) that was primarily driven by 27% lower odds of sudden cardiac death (adj OR per 1 SD, 0.73; 95% CI, 0.55–0.97). Long‐chain ω3‐PUFA levels in the top quartile were associated with 51% lower odds of cardiovascular death (adj OR 0.49; 95% CI, 0.27–0.86) and 63% lower odds of sudden cardiac death (adj OR, 0.37; 95% CI, 0.16–0.56). An attenuated relationship was seen for α‐linolenic acid and subsequent odds of cardiovascular (adj OR, 0.92; 95% CI, 0.74–1.14) and sudden cardiac death (adj OR, 0.91; 95% CI, 0.67–1.25). No significant relationship was observed between any ω3‐PUFAs and the odds of cardiovascular death unrelated to sudden cardiac death, myocardial infarction, atrial fibrillation, or early post‐acute coronary syndrome ventricular tachycardia.

Conclusions
In patients after non–ST‐segment–elevation‐acute coronary syndrome, plasma long‐chain ω3‐PUFAs are inversely associated with lower odds of sudden cardiac death, independent of traditional risk factors and lipids.

Epic Fail: About Two Photographic Projects
Authors: Lipszyc Weronika 
Published: April 2021

The paper discusses images of failure in Polish photography created in 1970–2000, drawing on three particular projects: Archeology of Photography by Jerzy Lewczyński and the exhibitions The New Documentalists (2006) and Postdocument: Missing Documents: Documents of the Polish Transformation After 1989 (2012). As such, it concentrates on documentary, or post-documentary, photography which suffers no illusions as to the mimetic power of the medium, but persists in hoping that photos can have social impact.
As the analyzed projects aim to create a critical picture of reality, they focus on spaces and people subject to exclusion and on the experience of failure (e.g., Unfinished Houses by Konrad Pustoła and Wojciech Wilczyk’s There’s No Such Thing as an Innocent Eye), as well as on the erosion of interpersonal relations (e.g., Aneta Grzeszykowska’s Album). Disappointments stemming from both the socialist reality and Polish capitalism mix with the desire to find and preserve what is intimate and authentic.
The discussed artists devote the majority of their attention to the problem of photography as a medium and its ability to generate social change. However, they remain fully aware of the fact that the very nature of the photographic image, with its media entanglements, makes it difficult to create an unadulterated reflection of reality; it also makes it difficult to accept anything that does not fit the visual poetics of success, anything old, damaged, démodé, or kitschy. Accordingly, the artists raise important questions about the rules for creating images in the photographic universe and about the possibility of transcending them to create a new type of document, one that would elude the rules of “dominant images” (a term first coined by Rafał Drozdowski), and to enable such a use of photography as was postulated by John Berger: rooted in personal experience and memory.
Die Geschichte in der Gegenwart sehen. Überlegungen zum Begriff der „kontaminierten Landschaften“ [Seeing History in the Present: Reflections on the Concept of “Contaminated Landscapes”]
Authors: Klei Alexandra 
Published: April 2021

Seeing History in the Present: Reflections on the Concept of “Contaminated Landscapes”The essay takes the 2014 book Kontaminierte Landschaften [Contaminated Landscapes] by the Austrian journalist and writer Martin Pollack as an opportunity to explore relationships between landscapes, (marked) places, and memory. In considering the relationship between the metaphorical (literary) image of contaminated landscapes and the actual crime scenes, I focus on the mass shootings of Jews by the German Nazis and their local supporters in the former Soviet Union. These specific crime scenes are used to explore the limits of Pollack’s metaphor and the problems it causes. The central arguments are presented using concrete examples provided by seven photographs.Widzieć historię w teraźniejszości. Refleksje nad pojęciem „skażonych krajobrazów”W artykule książka Skażone krajobrazy (2014) austriackiego dziennikarza i pisarza Martina Pollacka staje się punktem wyjścia do badania związków między krajobrazami, (naznaczonymi) miejscami i pamięcią. Relacje między metaforycznym (literackim) obrazem skażonych krajobrazów a realnymi miejscami zbrodni rozważam na przykładzie masowych rozstrzelań Żydów dokonanych w byłym Związku Radzieckim przez niemieckich nazistów i ich miejscowych stronników. Te konkretne miejsca zbrodni pomagają zbadać granice zastosowania metafory Pollacka i powodowane przez nią problemy. Najważniejsze wnioski zaprezentowałam na konkretnych przykładach siedmiu fotografii.
“Herbarium Polonorum” (“Heimatphotographie”)
Authors: Janicka Elżbieta 
Published: April 2021

The main theme of the text is the wartime and postwar history of the area of the German Nazi extermination camp Treblinka II, seen from the perspective of the production of landscape – with a special focus on the identity aspect, i.e. the nationalization of nature and the naturalization of the nation. The argument refers to imaging conventions of nature and ethnographic photography, like the German Heimatphotographie and the Polish Fatherland Photography, that go along with landscape production. This paper also touches upon the issue of classification as the principle organizing the workings of the human mind as well as the uses made of classification in terms of cognition and identity – up to and including the deadly consequences thereof. Another crucial point of reference is the history of the herbarium as a form of organizing knowledge (Maria Sibylla Merian, Rosa Luxemburg, Szymon Syreński) and its connections with the visual arts (Krzysztof Jung, Alina Szapocznikow). The rich iconography illustrates the analyzed representation patterns, with particular focus on the axiosemiotics of Polish antisemitism, going back to its elitist forms in Jagiellonian Poland. The text summarizes fifteen years of the author’s work on Herbarium, a photographic project carried out on the site of the former German Nazi extermination camp Treblinka II.

Development Processes of the Explosive Cyclones over the Northwest Pacific: Potential Vorticity Tendency Inversion
Authors: Kang Joonsuk M. , Son Seok-Woo 
Published: April 2021

AbstractA novel method that quantitatively evaluates the development processes of extratropical cyclones is devised and applied to the explosive cyclones over the northwest Pacific in the cold season (October–April). By inverting the potential vorticity (PV) tendency equation, the contribution of dynamic and thermodynamic processes at different levels to explosive cyclone development is quantified. In terms of geostrophic vorticity tendency at 850 hPa, which is utilized to quantify cyclone development, the leading factors for the explosive cyclone intensification are upper-level PV advection by the mean zonal flow and the PV production from latent heating. However, explosive cyclones are also subject to hindrances from vertical and meridional PV advections. Quantitatively, the sum of thermodynamic contributions by the latent heating, vertical PV advection, and surface temperature tendency is about 1.6 times more important than the dynamical PV redistribution by horizontal advections on the explosive cyclone intensification. This result confirms the dominant role of thermodynamic processes in explosive cyclone development over the northwest Pacific. It turns out from further analysis that the interactions of lower-level anomalous flows are important for thermodynamic processes, whereas the advections by the upper-level mean flow are primary for dynamic processes.
The use of serially complete station data to improve the temporal continuity of gridded precipitation and temperature estimates
Authors: Tang Guoqiang , Clark Martyn P. , Papalexiou Simon Michael 
Published: April 2021

AbstractStations are an important source of meteorological data, but often suffer from missing values and short observation periods. Gap filling is widely used to generate serially complete datasets (SCDs), which are subsequently used to produce gridded meteorological estimates. However, the value of SCDs in spatial interpolation is scarcely studied. Based on our recent efforts to develop a SCD over North America (SCDNA), we explore the extent to which gap filling improves gridded precipitation and temperature estimates. We address two specific questions: (1) Can SCDNA improve the statistical accuracy of gridded estimates in North America? (2) Can SCDNA improve estimates of trends on gridded data? In addressing these questions, we also evaluate the extent to which results depend on the spatial density of the station network and the spatial interpolation methods used. Results show that the improvement in statistical interpolation due to gap filling is more obvious for precipitation, followed by minimum temperature and maximum temperature. The improvement is larger when the station network is sparse and when simpler interpolation methods are used. SCDs can also notably reduce the uncertainties in spatial interpolation. Our evaluation across North America from 1979 to 2018 demonstrates that SCDs improve the accuracy of interpolated estimates for most stations and days. SCDNA-based interpolation also obtains better trend estimation than observation-based interpolation. This occurs because stations used for interpolation could change during a specific period, causing changepoints in interpolated temperature estimates and affect the long-term trends of observation-based interpolation, which can be avoided using SCDNA. Overall, SCDs improve the performance of gridded precipitation and temperature estimates.

Authors: Hillyer Margot , Matiz Luz Adriana , Robbins-Milne Laura , Friedman Suzanne 
Published: April 2021

Background Nearly all pediatric patients in our setting meet high-risk criteria for lead exposure based on screening recommendations and guidelines. Implementation of screening and testing has been inconsistent. Objective To assess the utility and efficacy of performing universal lead testing between ages 1 and 5 at an urban academic pediatric practice. Methods Retrospective review of patients with routine lead testing between 2010 and 2015. Key variables included demographics, serum lead level, and behavioral diagnoses. Results A total of 6597 serum lead levels from 3274 patients were reviewed. Forty-seven samples (0.7%) from 24 patients (0.7%) were elevated. Of the 24 patients with elevated lead, 75% were identified at age 1 or 2. Sixty-seven percent of patients with first elevated lead level at age 3 or older had a diagnosis of developmental delay. Conclusion Routine testing of high-risk patients yielded minimal specificity in identifying elevated lead levels, especially in patients older than 3 years and without developmental delay.
The effect of backside elements on the light emission of a plastic optical fiber assembly
Authors: Cho Hakyung , Song Hayoung 
Published: April 2021

With the recent increase in leisure time and wellbeing trends, the number of individuals who enjoy nighttime leisure activities has rapidly increased. Thus, the demand for luminous night safety clothing ensuring safety and that is also fashionable is increasing. Although higher visibility is important, studies on the influence of the backside elements of optical fiber materials on light emission are limited. The main components of the plastic optical fiber assembly in this study are the plastic optical fiber and backside elements, consisting of retroreflective material, and the backside sheet. The effects of the four types of retroreflective material, which are low, medium, high, and ultra-high luminance types, and the color of the backside sheet, white or black, on the luminance of the plastic optical fiber assembly are evaluated in bright, dusky, and dark environments. The results are analyzed using the statistical analysis software, SPSS 20.0. In the dusky environment, the plastic optical fiber assembly with prism material (80.78 ± 2.17) exhibits the highest luminance. However, there was no difference between the plastic optical fiber assembly with high- (38.52 ± 1.27) and medium-retroreflective material (36.76 ± 0.68). In the dark environment, the plastic optical fiber assembly with the prism material shows the highest luminance (66.83 ± 0.24), and there is no difference between the plastic optical fiber assembly with the low- (24.43 ± 0.42), medium- (24.63 ± 0.36), and high-retroreflective material (25.12 ± 0.42). Also, the luminance of the plastic optical fiber assembly with the white backside sheet is higher than that with the black backside sheet for all retroreflective material in dusky and dark environments. In summary, the optimal constitution of a plastic optical fiber assembly’s backside element is the retroreflective material of a prism type with the white backside color.
Buen vivir and the Making of Indigenous Territories in the Peruvian Amazon
Authors: Merino Roger 
Published: April 2021

Awajun, Wampis, and other Amazonian indigenous peoples in Peru have acquired title to the collective property of their native communities as a legal strategy for the defense of their ancestral territory. This strategy, however, has failed to stop the expansion of extractive industries and the degradation of their livelihoods. In response, indigenous peoples in the northern Amazon are proposing the legal recognition of their “integral territory” under a politics of buen vivir. This new model for territorial governance is aimed at transforming indigenous peoples from ethnic communities with property entitlements to nations with territorial rights. Los awajun, wampis y otros pueblos indígenas amazónicos en Perú han adquirido el título de propiedad colectiva de sus comunidades nativas como estrategia legal para la defensa de su territorio ancestral. Esta estrategia, sin embargo, no ha logrado detener la expansión de las industrias extractivas y la degradación de sus medios de vida. En respuesta, los pueblos indígenas del norte de la Amazonía proponen el reconocimiento legal de su “territorio integral” bajo una política de buen vivir. Este nuevo modelo de gobierno territorial tiene por objeto transformar a los pueblos indígenas de comunidades étnicas con derechos de propiedad a naciones con derechos territoriales.
Living Well and Health Practices among Aymara People in Northern Chile
Authors: Carreño-Calderón Alejandra 
Published: April 2021

The current Chilean health model seeks to promote health equity among indigenous peoples by means of state intercultural health programs. As implemented regionally, these have been widely criticized as depoliticizing mechanisms meant to dominate the indigenous population. Study of the experiences of several indigenous health agents and associations fostered by these programs reveals that the strategic use of the concept of living well by indigenous peoples raises questions about the issues that are to be included in or excluded from the intercultural medical field. El actual modelo de salud chileno busca promover el acceso equitativo a la salud entre los pueblos indígenas a través de programas estatales de salud intercultural. Tal y como se aplican a nivel regional, estos han sido ampliamente criticados como mecanismos de despolitización diseñados para dominar a la población indígena. El estudio de las experiencias de varios agentes y asociaciones de salud indígenas impulsados por estos programas revela que el uso estratégico del concepto del buen vivir por parte de los pueblos indígenas plantea interrogantes sobre qué asuntos deben o no incluirse en el campo médico intercultural.

Authors: Bendrik Regina , Kallings Lena V , Bröms Kristina , Kunanusornchai Wanlop , Emtner Margareta 
Published: April 2021

Objective: To evaluate whether physical activity on prescription, comprising five sessions, was more effective in increasing physical activity than a one-hour advice session after six months. Design: Randomized, assessor-blinded, controlled trial. Setting: Primary care. Subjects: Patients with clinically verified osteoarthritis of the hip or knee who undertook less than 150 minute/week of moderate physical activity, and were aged 40–74 years. Interventions: The advice group ( n = 69) received a one-hour session with individually tailored advice about physical activity. The physical activity on prescription group ( n = 72) received individually tailored physical activity recommendations with written prescription, and four follow-ups during six months. Main measures: Patients were assessed at baseline and six months: physical activity (accelerometer, questionnaires); fitness (six-minute walk test, 30-second chair-stand test, maximal step-up test, one-leg rise test); pain after walking (VAS); symptoms (HOOS/KOOS); and health-related quality of life (EQ-5D). Results: One hundred four patients had knee osteoarthritis, 102 were women, and mean age was 60.3 ± 8.3 years. Pain after walking decreased significantly more in the prescription group, from VAS 31 ± 22 to 18 ± 23. There was no other between groups difference. Both groups increased self-reported activity minutes significantly, from 105 (95% CI 75–120) to 165 (95% CI 135–218) minute/week in the prescription group versus 75 (95% CI 75–105) to 150 (95% CI 120–225) in the advice group. Also symptoms and quality of life improved significantly in both groups. Conclusion: Individually tailored physical activity with written prescription and four follow-ups does not materially improve physical activity level more than advice about osteoarthritis and physical activity.

Published: April 2021

Background Takayasu arteritis (TA), a systemic large-vessel vasculitis, was reported to have high incidence of spondyloarthropathy. Purpose To evaluate the prevalence of inflammatory sacroiliitis in patients with TA that underwent abdominal/pelvic magnetic resonance imaging (MRI) examinations as part of their vasculitis work-up. Material and Methods Consecutive abdominal/pelvic MRI examinations of 34 patients with TA fulfilling the 1990 ACR criteria and 34 age- and gender-matched controls performed between 2008 and 2020 were retrospectively reviewed for the presence sacroiliitis. The presence of active and structural lesions was scored twice (with a one-month interval between reads) by one reader. Structural lesions were also evaluated on computed tomography, when available, and correlated to MRI findings. Clinical data were extracted from the patients’ clinical files. MRI scores were compared between the study and control groups and correlated with the clinical data. Results Sacroiliitis was evident in 11.7% of the TA group examinations compared to 0.3% in the control group ( P = 0.6). Participants with TA had significantly more erosions and fat deposition compared to the control group (Study: 0.01/0.03, Control: 0/0, P = 0.03/0.003, respectively). However, mean sacroiliitis score was not significantly different (Study: 1.06, Control: 0.78, P = 0.015). Of the four patients with TA and sacroiliitis, 3 (75%) had a diagnosis of inflammatory bowel disease (IBD). Conclusion Sacroiliitis was detected in 11.7% of abdominal MRI examinations of patients with TA, 75% of which had associated IBD, suggesting that both IBD and sacroiliitis should be routinely screened in the TA population as their presence may influence treatment decisions.

Objective As first-line treatments for newly diagnosed adult immune thrombocytopenia (ITP), high-dose dexamethasone (HD-DXM) and conventional-dose prednisone achieve good initial responses, but their long-term efficacy is poor. To improve the long-term outcome of newly diagnosed ITP, we explored the efficacy and safety of HD-DXM with sequential prednisone maintenance therapy. Methods This retrospective study in a real-world setting assessed 72 consecutive newly diagnosed ITP patients administered first-line HD-DXM with sequential prednisone maintenance therapy from 1 June 2016 to 31 December 2019. Results Seventy patients obtained response (97.2%), and 55 achieved sustained response (SR) (76.4%). Fifty-three obtained complete remission (CR) (73.6%), and 39 achieved continuous CR at 6 months (54.2%). Among 36 anti-nuclear antibody-positive patients, 100% achieved response, and 28 achieved CR (77.8%). Among 24 antithyroid antibody-positive patients, 23 (95.8%) achieved response, and 20 achieved CR (83.3%). For patients with initial response, the 12-month probability of SR was 78.6%. For patients with initial CR, the 12-month probability of continuous CR was 64.2%. At 12 months, 21.4% of patients with initial response and 11.3% of patients with initial CR showed loss of treatment response. Conclusions HD-DXM with sequential prednisone as the first-line treatment for newly diagnosed ITP patients may achieve good clinical efficacy.
