TL;DR: This work aims to standardize the histopathological assessment of synovial membrane specimens in order to contribute to the diagnostics of rheumatic and non‐rheumatic joint diseases.
Abstract: Aims : To standardize the histopathological assessment of synovial membrane specimens in order to contribute to the diagnostics of rheumatic and non-rheumatic joint diseases.
Methods and results : Three features of chronic synovitis (enlargement of lining cell layer, cellular density of synovial stroma, leukocytic infiltrate) were semiquantitatively evaluated (from 0, absent to 3, strong) and each feature was graded separately. The sum provided the synovitis score, which was interpreted as follows: 0–1, no synovitis; 2–4, low-grade synovitis; 5–9, high-grade synovitis. Five hundred and fifty-nine synovectomy specimens were graded by two independent observers. Clinical diagnoses were osteoarthrosis (n = 212), post-traumatic arthritis (n = 21), rheumatoid arthritis (n = 246), psoriatic arthritis (n = 22), reactive arthritis (n = 9), as well as controls (n = 49) from autopsies of patients without joint damage. Median synovitis scores when correlated with clinical diagnoses were: controls 1.0, osteoarthritis 2.0, post-traumatic arthritis 2.0, psoriatic arthritis 3.5, reactive arthritis 5.0 and rheumatoid arthritis 5.0. The scores differed significantly between most disease groups, especially between degenerative and rheumatic diseases. A high-grade synovitis was strongly associated with rheumatic joint diseases (P < 0.001, sensitivity 61.7%, specificity 96.1%). The correlation between the two observers was high (r = 0.941).
Conclusion : The proposed synovitis score is based on well-defined, reproducible histopathological criteria and may contribute to diagnosis in rheumatic and non-rheumatic joint diseases.

TL;DR: The term S&G is used for all medical relevant differences between women and men in the present review to include the inclusion of the gender dimension into biomedical research since ‘it helps improve the scientific quality …’.
Abstract: In the vast majority of cardiovascular diseases (CVDs), there are well-described differences between women and men in epidemiology, pathophysiology, clinical manifestations, effects of therapy, and outcomes.1–3 These differences arise on one hand from biological differences among women and men, which are called sex differences. They are due to differences in gene expression from the sex chromosomes and subsequent differences in sexual hormones leading to differences in gene expression and function in the CV system, e.g. in vascular function and NO signalling, in myocardial remodelling under stress, or metabolism of drugs by sex-specific cytochrome expression. Sex differences are frequently reproducible in animal models. In contrast, gender differences are unique to the human. They arise from sociocultural processes, such as different behaviours of women and men; exposure to specific influences of the environment; different forms of nutrition, lifestyle, or stress; or attitudes towards treatments and prevention. These are equally important for CVDs. Both sex and gender (S&G) influence human development ( Figure 1 ). Since it is almost impossible to distinguish properly between effects of S&G in the medical field, the EUGenMed writing group decided to discuss both of them together and to use the term S&G for all medical relevant differences between women and men in the present review.

TL;DR: The results suggest the independent prognostic relevance of CTCs both before and after adjuvant chemotherapy in a large prospective trial of patients with primary breast cancer.
Abstract: Background Circulating tumor cells (CTCs) have been shown to predict reduced survival outcomes in metastatic breast cancer. Methods CTCs were analyzed in 2026 patients with early breast cancer before adjuvant chemotherapy and in 1492 patients after chemotherapy using the CellSearch System. After immuno-magnetic enrichment for cells expressing the epithelial-cell adhesion molecule, CTCs were defined as nucleated cells expressing cytokeratin and lacking CD45. The patients were followed for a median of 35 months (range = 0–54). Kaplan–Meier analyses and the log-rank test were used for survival analyses. All statistical tests were two-sided. Results Before chemotherapy, CTCs were detected in 21.5% of patients (n = 435 of 2026), with 19.6% (n = 136 of 692) of node-negative and 22.4% (n = 299 of 1334) of node-positive patients showing CTCs (P < .001). No association was found with tumor size, grading, or hormone receptor status. After chemotherapy, 22.1% of patients (n = 330 of 1493) were CTC positive. The presence of CTCs was associated with poor disease-free survival (DFS; P < .0001), distant DFS (P < .001), breast cancer-specific survival (P = .008), and overall survival (OS; P = .0002). CTCs were confirmed as independent prognostic markers in multivariable analysis for DFS (hazard ratio [HR] = 2.11; 95% confidence interval [CI] = 1.49 to 2.99; P < .0001) and OS (HR = 2.18; 95% CI = 1.32 to 3.59; P = .002). The prognosis was worst in patients with at least five CTCs per 30 mL blood (DFS: HR = 4.51, 95% CI = 2.59 to 7.86; OS: HR = 3.60, 95% CI = 1.56 to 8.45). The presence of persisting CTCs after chemotherapy showed a negative influence on DFS (HR = 1.12; 95% CI = 1.02 to 1.25; P = .02) and on OS (HR = 1.16; 95% CI = 0.99 to 1.37; P = .06)

TL;DR: Improved standardization of available invasive and noninvasive diagnostic tools and a consensus on their specific use are needed to allow specific diagnosis and stratification of patient cohorts for the implementation of aetiology-based therapies.
Abstract: Inflammatory cardiomyopathy, characterized by inflammatory cell infiltration into the myocardium and a high risk of deteriorating cardiac function, has a heterogeneous aetiology. Inflammatory cardiomyopathy is predominantly mediated by viral infection, but can also be induced by bacterial, protozoal or fungal infections as well as a wide variety of toxic substances and drugs and systemic immune-mediated diseases. Despite extensive research, inflammatory cardiomyopathy complicated by left ventricular dysfunction, heart failure or arrhythmia is associated with a poor prognosis. At present, the reason why some patients recover without residual myocardial injury whereas others develop dilated cardiomyopathy is unclear. The relative roles of the pathogen, host genomics and environmental factors in disease progression and healing are still under discussion, including which viruses are active inducers and which are only bystanders. As a consequence, treatment strategies are not well established. In this Review, we summarize and evaluate the available evidence on the pathogenesis, diagnosis and treatment of myocarditis and inflammatory cardiomyopathy, with a special focus on virus-induced and virus-associated myocarditis. Furthermore, we identify knowledge gaps, appraise the available experimental models and propose future directions for the field. The current knowledge and open questions regarding the cardiovascular effects associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are also discussed. This Review is the result of scientific cooperation of members of the Heart Failure Association of the ESC, the Heart Failure Society of America and the Japanese Heart Failure Society.
