The norms, values, and practices of collectivist societies in Sub-Saharan Africa and the low research literacy pose challenges to the conduct of clinical trials. Civil-society organizations, members of community advisory boards and ethics committees, young persons, COVID-19 survivors, researchers, government, and the private sector are assets for the implementation and translation of COVID-19 related clinical trials. Adapting ethics guidelines to the socio-cultural context of the region can facilitate achieving the aim of stakeholder engagement.

To analyse the clinical significance of anti-Ro52 autoantibodies that target TRIM21 protein and occur in a variety of connective tissue diseases (CTD), 4782 cases with blood tested positive for anti-Ro52 antibodies between January 2016 and September 2017 in Drum Tower Hospital were enrolled.

Anti-Ro52 and anti-Ro60 were measured using the immunoblotting method together with antibodies against other extractable nuclear antigens at the time of the patient's first visit.

In this cohort, females accounted for the majority of all subjects (75.9%) and the average age was 47.25years old. About 97.4% were diagnosed as having various diseases, in which around 2/3 were CTDs. The incidence of CTD in patients with merely anti-Ro52 was lower than those with both anti-Ro52 and anti-Ro60 (54.7% vs 85.5% for all patients and 53.3% vs 87.1% for inpatients, both P<.0001). Amongst CTDs, the incidence of systemic lupus erythematosus was significantly decreased, while the incidence of inflammatory myositis as well as undifferentiated connective tissue diseases was increased in anti-Ro52 single-positive group. For patients with either CTDs or non-CTDs, respiratory involvement was more common in patients with merely anti-Ro52 (67.6% vs 34.7%, P<.0001 and 53.2% vs 36.3%, P<.01). Sub-analysis revealed that both interstitial lung disease and pulmonary infection were related to anti-Ro52 in CTD inpatients (P<.0001 and P<.05).

Our study shows that anti-Ro52 could occur in various clinical conditions. These antibodies may appear in the early stage of CTD with the lung an important target organ, thus their presence warrants long-term follow-up.

It is important to reach out to the public, scientific and medical communities, and those who stutter with a goal to raise awareness about stuttering. In this short perspective, we argue that to educate, advocate, and spread awareness about stuttering, we need role models, support, and opportunities.Patients with autoimmune diseases (AIDs) may develop lymphoproliferative disorders (LPDs) during treatment with immunosuppressive agents (IS) such as methotrexate (MTX), biological agents, or tacrolimus. Some LPDs in patients with AIDs (AID-LPDs) regress after withdrawal of IS, and a high incidence of Epstein-Barr virus (EBV) positivity in such patients has been reported. To identify characteristics and factors predictive of the response to treatment and disease progression, we retrospectively analyzed clinical and histopathological data for 81 patients with AID-LPDs. Almost all of them (96%) had been treated with MTX. Diffuse large B cell lymphoma was the most common LPD type (61%) and seven patients (9%) had classical Hodgkin lymphoma (CHL). EBV was detected by in situ hybridization with an EBV-encoded small RNA (EBER) probe in 43% of the examined cases. In 59 patients, IS was discontinued as the initial treatment, resulting in regression of LPDs in 69% of them, and multivariate analysis showed that EBER positivity was an independent factor predictive of such regression (p = 0.022). Two-year progression-free survival (PFS) and overall survival for the patients overall were 63% and 83%, respectively. Poor PFS was associated with advanced stage (p = 0.024), worse performance status (PS, p = 0.031), CHL histology (p = 0.013), and reactivation of EBV-related antibodies (p = 0.029). In conclusion, EBV positivity demonstrated using an EBER probe is useful for prediction of successful regression after withdrawal of IS in patients with AID-LPDs. Patients with advanced stage disease, worse PS, CHL histology, or reactivation of EBV-related antibodies should be closely monitored after initial treatment.Course specific learning outcomes are an important tool to define the scope of a course and can be very helpful when designing experiments and assessments. With slight modification, these learning outcomes can serve as a guide when transitioning to the distance learning format especially in courses with a traditional lab. Here we present such an example for the biophysical chemistry course.Disorder of lipid metabolism has become an urgent health problem that brings about a variety of metabolic syndromes, including hepatic steatosis, adipose tissue dysfunction, diabetes and obesity. Circular RNAs (circRNAs), a class of emerging RNA molecules with unique structure and extensive effects, have been verified to participate in various biological programs through distinct mechanisms, especially in lipid-related processes. In this review, the biogenesis, characteristics, and functional mechanisms of circRNAs are discussed. Furthermore, the methods for circRNA identification and expression profiles of circRNAs associated with adipogenesis and lipid metabolism are described. Additionally, we emphasize the regulatory roles of circRNAs in adipogenesis, lipid metabolism, and lipid-related diseases. Finally, the diagnostic and therapeutic potential of circRNAs is highlighted, showing potential for the clinical application of circRNAs in the treatment of lipid-related diseases in the near future.
