The Media Bias Taxonomy: A Systematic Literature Review on the Forms and Automated Detection of Media Bias

The way the media presents events can significantly affect public perception, which in turn can alter people's beliefs and views. Media bias describes a one-sided or polarizing perspective on a topic. This article summarizes the research on computational methods to detect media bias by systematically reviewing 3140 research papers published between 2019 and 2022. To structure our review and support a mutual understanding of bias across research domains, we introduce the Media Bias Taxonomy, which provides a coherent overview of the current state of research on media bias from different perspectives. We show that media bias detection is a highly active research field, in which transformer-based classification approaches have led to significant improvements in recent years. These improvements include higher classification accuracy and the ability to detect more fine-granular types of bias. However, we have identified a lack of interdisciplinarity in existing projects, and a need for more awareness of the various types of media bias to support methodologically thorough performance evaluations of media bias detection systems. Concluding from our analysis, we see the integration of recent machine learning advancements with reliable and diverse bias assessment strategies from other research areas as the most promising area for future research contributions in the field

Blood pH Analysis in Combination with Molecular Medical Tools in Relation to COVID-19 Symptoms †

The global outbreak of SARS-CoV-2/COVID-19 provided the stage to accumulate an enormous biomedical data set and an opportunity as well as a challenge to test new concepts and strategies to combat the pandemic. New research and molecular medical protocols may be deployed in different scientific fields, e.g., glycobiology, nanopharmacology, or nanomedicine. We correlated clinical biomedical data derived from patients in intensive care units with structural biology and biophysical data from NMR and/or CAMM (computer-aided molecular modeling). Consequently, new diagnostic and therapeutic approaches against SARS-CoV-2 were evaluated. Specifically, we tested the suitability of incretin mimetics with one or two pH-sensitive amino acid residues as potential drugs to prevent or cure long-COVID symptoms. Blood pH values in correlation with temperature alterations in patient bodies were of clinical importance. The effects of biophysical parameters such as temperature and pH value variation in relation to physical-chemical membrane properties (e.g., glycosylation state, affinity of certain amino acid sequences to sialic acids as well as other carbohydrate residues and lipid structures) provided helpful hints in identifying a potential Achilles heel against long COVID. In silico CAMM methods and in vitro NMR experiments (including 31P NMR measurements) were applied to analyze the structural behavior of incretin mimetics and SARS-CoV fusion peptides interacting with dodecylphosphocholine (DPC) micelles. These supramolecular complexes were analyzed under physiological conditions by 1H and 31P NMR techniques. We were able to observe characteristic interaction states of incretin mimetics, SARS-CoV fusion peptides and DPC membranes. Novel interaction profiles (indicated, e.g., by 31P NMR signal splitting) were detected. Furthermore, we evaluated GM1 gangliosides and sialic acid-coated silica nanoparticles in complex with DPC micelles in order to create a simple virus host cell membrane model. This is a first step in exploring the structure–function relationship between the SARS-CoV-2 spike protein and incretin mimetics with conserved pH-sensitive histidine residues in their carbohydrate recognition domains as found in galectins. The applied methods were effective in identifying peptide sequences as well as certain carbohydrate moieties with the potential to protect the blood–brain barrier (BBB). These clinically relevant observations on low blood pH values in fatal COVID-19 cases open routes for new therapeutic approaches, especially against long-COVID symptoms

The origins and spread of domestic horses from the Western Eurasian steppes

This is the final version. Available on open access from Nature Research via the DOI in this recordData availability: All collapsed and paired-end sequence data for samples sequenced in this study are available in compressed fastq format through the European Nucleotide Archive under accession number PRJEB44430, together with rescaled and trimmed bam sequence alignments against both the nuclear and mitochondrial horse reference genomes. Previously published ancient data used in this study are available under accession numbers PRJEB7537, PRJEB10098, PRJEB10854, PRJEB22390 and PRJEB31613, and detailed in Supplementary Table 1. The genomes of ten modern horses, publicly available, were also accessed as indicated in their corresponding original publications57,61,85-87.NOTE: see the published version available via the DOI in this record for the full list of authorsDomestication of horses fundamentally transformed long-range mobility and warfare. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling at Botai, Central Asia around 3500 BC. Other longstanding candidate regions for horse domestication, such as Iberia and Anatolia, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 BC, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 BC driving the spread of Indo-European languages. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium BC Sintashta culture

Environmental barriers, person-environment fit and mortality among community-dwelling very old people

Background. Environmental barriers are associated with disability-related outcomes in older people but little is known of the effect of environmental barriers on mortality. The aim of this study was to examine whether objectively measured barriers in the outdoor, entrance and indoor environments are associated with mortality among community-dwelling 80- to 89-year-old single-living people. Methods. This longitudinal study is based on a sample of 397 people who were single-living in ordinary housing in Sweden. Participants were interviewed during 2002–2003, and 393 were followed up for mortality until May 15, 2012. Environmental barriers and functional limitations were assessed with the Housing Enabler instrument, which is intended for objective assessments of Person-Environment (P-E) fit problems in housing and the immediate outdoor environment. Mortality data were gathered from the public national register. Cox regression models were used for the analyses. Results. A total of 264 (67%) participants died during follow-up. Functional limitations increased mortality risk. Among the specific environmental barriers that generate the most P-E fit problems, lack of handrails in stairs at entrances was associated with the highest mortality risk (adjusted RR 1.55, 95% CI 1.14-2.10), whereas the total number of environmental barriers at entrances and outdoors was not associated with mortality. A higher number of environmental barriers indoors showed a slight protective effect against mortality even after adjustment for functional limitations (RR 0.98, 95% CI 0.96-1.00). Conclusion. Specific environmental problems may increase mortality risk among very-old single-living people. However, the association may be confounded by individuals’ health status which is difficult to fully control for. Further studies are called for.peerReviewe

Male adolescent with cardiac rupture after blunt thoracic trauma

Blunt cardiac injury, including a rupture of the atria or ventricle, is most commonly caused by motor vehicle collisions and falls from great heights. A rupture of a cardiac chamber is an extremely rare diagnosis with a high mortality rate. The best chance at survival can only be accomplished with timely intervention.To raise awareness of this potentially life-threatening injury, we describe the case of a male adolescent with cardiac rupture after blunt thoracic trauma. While the focused assessment with sonography in trauma (FAST) examination was negative, an additional CT showed pericardial effusion. During the operation a rupture of the right ventricle was observed.Even though the physical recovery of our patient is remarkable, the traumatic event still affects his mental well-being and activities in daily life. This case emphasises the need of a multidisciplinary approach to achieve the best possible physical and psychological recovery in multitrauma patients.</p

Major prognostic role of Ki67 in localized adrenocortical carcinoma after complete resection

Background: Recurrence of adrenocortical carcinoma (ACC) even after complete (R0) resection occurs frequently. Objective: The aim of this study was to identify markers with prognostic value for patients in this clinical setting. Design, Setting, and Participants: From the German ACC registry, 319 patients with the European Network for the Study of Adrenal Tumors stage I-III were identified. As an independent validation cohort, 250 patients from three European countries were included. Outcome Measurements and Statistical Analysis: Clinical, histological, and immunohistochemical markers were correlated with recurrence-free (RFS) and overall survival (OS). Results: Although univariable analysis within the German cohort suggested several factors with potential prognostic power, upon multivariable adjustment only a few including age, tumor size, venous tumor thrombus (VTT), and the proliferation marker Ki67 retained significance. Among these, Ki67 provided the single best prognostic value for RFS (hazard ratio [HR] for recurrence, 1.042 per 1% increase; P <.0001) and OS (HR for death, 1.051; P <.0001) which was confirmed in the validation cohort. Accordingly, clinical outcome differed significantly between patients with Ki6

Prognostic Role of Overt Hypercortisolism in Completely Operated Patients with Adrenocortical Cancer

Although prognostic parameters are important to guide adjuvant treatment, very few have been identified in patients with completely resected adrenocortical carcinoma (ACC).To assess the prognostic role of clinical symptoms of hypercortisolism in a large series of patients with completely resected ACC.A total of 524 patients followed at referral centers for ACC in Europe and the United States entered the study. Inclusion criteria were ?18 yr of age, a histologic diagnosis of ACC, and complete surgery (R0). Exclusion criteria were a history of other malignancies and adjuvant systemic therapies other than mitotane.All ACC patients were completely resected, and adjuvant mitotane therapy was prescribed at the discretion of the investigators.The primary end point was overall survival (OS). The secondary end points were recurrence-free survival (RFS) and the efficacy of adjuvant mitotane therapy according to cortisol secretion.Overt hypercortisolism was observed in 197 patients (37.6%). Patients with cortisol excess were younger (p=0.002); no difference according to sex and tumor stage was observed. The median follow-up of the series was 50 mo. After adjustment for sex, age, tumor stage, and mitotane treatment, the prognostic significance of cortisol excess was highly significant for both RFS (hazard ratio [HR]: 1.30; 95% confidence interval [CI], 1.04-2.62; p=0.02) and OS (HR: 1.55; 95% CI, 1.15-2.09; p=0.004). Mitotane administration was associated with a reduction of disease progression (adjusted HR: 0.65; 95% CI, 0.49-0.86; p=0.003) that did not differ according to the patient's secretory status. A major limitation is that only symptomatic patients were considered as having hypercortisolism, thus excluding information on the prognostic role of elevated cortisol levels in the absence of a clinical syndrome.Clinically relevant hypercortisolism is a new prognostic factor in patients with completely resected ACC. The efficacy of adjuvant mitotane does not seem to be influenced by overt hypercortisolism. European Association of Urology. Published b

Cardiometabolic Disease Burden and Steroid Excretion in Benign Adrenal Tumors : A Cross-Sectional Multicenter Study.

BACKGROUND Benign adrenal tumors are commonly discovered on cross-sectional imaging. Mild autonomous cortisol secretion (MACS) is regularly diagnosed, but its effect on cardiometabolic disease in affected persons is ill defined. OBJECTIVE To determine cardiometabolic disease burden and steroid excretion in persons with benign adrenal tumors with and without MACS. DESIGN Cross-sectional study. SETTING 14 endocrine secondary and tertiary care centers (recruitment from 2011 to 2016). PARTICIPANTS 1305 prospectively recruited persons with benign adrenal tumors. MEASUREMENTS Cortisol excess was defined by clinical assessment and the 1-mg overnight dexamethasone-suppression test (serum cortisol: 138 nmol/L and absence of typical clinical Cushing syndrome [CS] features, definitive MACS [MACS-2]). Net steroid production was assessed by multisteroid profiling of 24-hour urine by tandem mass spectrometry. RESULTS Of the 1305 participants, 49.7% had NFAT ( = 649; 64.1% women), 34.6% had MACS-1 ( = 451; 67.2% women), 10.7% had MACS-2 ( = 140; 73.6% women), and 5.0% had CS ( = 65; 86.2% women). Prevalence and severity of hypertension were higher in MACS-2 and CS than NFAT (adjusted prevalence ratios [aPRs] for hypertension: MACS-2, 1.15 [95% CI, 1.04 to 1.27], and CS, 1.37 [CI, 1.16 to 1.62]; aPRs for use of ≥3 antihypertensives: MACS-2, 1.31 [CI, 1.02 to 1.68], and CS, 2.22 [CI, 1.62 to 3.05]). Type 2 diabetes was more prevalent in CS than NFAT (aPR, 1.62 [CI, 1.08 to 2.42]) and more likely to require insulin therapy for MACS-2 (aPR, 1.89 [CI, 1.01 to 3.52]) and CS (aPR, 3.06 [CI, 1.60 to 5.85]). Urinary multisteroid profiling revealed an increase in glucocorticoid excretion from NFAT over MACS-1 and MACS-2 to CS, whereas androgen excretion decreased. LIMITATIONS Cross-sectional design; possible selection bias. CONCLUSION A cardiometabolic risk condition, MACS predominantly affects women and warrants regular assessment for hypertension and type 2 diabetes.
