The aim of this study was to assess the effect of continuing immune suppressive therapy in solid organ transplant recipients (SOTR) with coronavirus disease 2019 (COVID-19).
Systematic review and meta-analysis of data on 202 SOTR with COVID-19, published as case reports or case series. We extracted clinical, hemato-chemical, imaging, treatment, and outcome data.
Most patients were kidney recipients (61.9%), males (68.8%), with median age of 57years. The majority was on tacrolimus (73.5%) and mycophenolate (65.8%). Mortality was 18.8%, but an equal proportion was still hospitalized at last follow up. Immune suppressive therapy was withheld in 77.2% of patients, either partially or completely. Tacrolimus was continued in 50%. One third of survivors that continued immunosuppressants were on dual therapy plus steroids. None of those who continued immunosuppressants developed critical COVID-19 disease. Age (OR 1.07, 95% CI 1-1.11, P=.001) and lopinavir/ritonavir use (OR 3.3, 95%CI 1.2-8.5, P=.013) were independent predictors of mortality while immunosuppression maintenance (OR 0.067, 95% CI 0.008-0.558, P=.012) and tacrolimus continuation (OR 0.3, 95% CI 0.1-0.7, P=.013) were independent predictors of survival.
Our data suggest that maintaining immune suppression might be safe in SOTR with moderate and severe COVID-19. Specifically, receiving tacrolimus could be beneficial for COVID-19 SOTR. AZD1080 concentration Because of the quality of the available evidence, no definitive guidance on how to manage SOTR with COVID-19 can be derived from our data.

Evaluation of MSCs from muscles of different origins improves our understanding of their regenerative potential. The present study compared the stemness, cell proliferation, migration potential, myogenic differentiation (MD), and multipotency of MSCs for four developmentally different muscles of ovine origin. MSCs were isolated from the hind limb (HL), diaphragm (DI), extraocular (EO), and masseter (MS) muscles. Cell proliferation, migration, and stemness were examined using sulforhodamine B, and colony formation assays. Evaluation of multipotency was examined using histological and morphometric analyses, alkaline phosphatase (ALP) activity, and the expression of myogenic, adipogenic, and osteogenic markers using RT-qPCR. Data were statistically analysed using analysis of variance. The results revealed that all experimental groups expressed stem cell markers paired box transcription factor Pax7, α7-integrin, CD90, and platelet-derived growth factor receptor alpha. DI and HL muscle cells displayed higher proliferation, migration, and colony formation capacities compared to the EO and MS muscle cells. HL and DI muscle cells showed increased MD, as indicated by myotube formation and relative expression of MyoD at day 7 and Myogenin at day 14. Although MS and EO muscle cells displayed impaired MD, these cells were more prone to adipogenic differentiation, as indicated by Oil Red O staining and upregulated fatty acid-binding protein 4 and peroxisome proliferator-activated receptor gamma expression. DI muscle cells demonstrated a higher osteogenic differentiation capability, as shown by the upregulation of osteopontin expression and an elevated ALP activity. Our data indicate that ovine HL and DI MSCs have a higher regenerative and multipotent potential than the EO and MS muscle cells. These results could be valuable for regional muscle biopsies and cell-based therapies.This article examines knowledge production in the sociology of music. Focusing on the idea of cool music, we interrogate the nature of music researchers' relationship with their object of research. While the qualification and connotation of cool is widespread in popular music, sociology has largely neglected to engage with it as an object of research. Instead, the sociological investigation of music audiences is divided between two opposed but co-constructed paradigms that ultimately do not account for how cool emerges as a qualifier and connotation, how it performs as a discourse on music, and to what effect. Using the example of aging music researchers as a departure point, we examine how the cool connotations of music function as a mode of discourse that legitimates particular knowledge, practice, and taste, demarcating insider/outsider status. We explore how music acquires social connotations such as "cool" and whether that alters music researchers' approaches to it. We argue that apart from the disclosure of inclinations, social characteristics, and relationships to the object of research (music scenes, preferences, fandom, and so on), the tradition of reflexive empirical perspectives in music sociology should incorporate further deconstruction of the transformative dimensions in the relations between music and researcher. Music, as a complex and dynamic object, thus, requires sociology to produce accounts that both encompass people's enjoyment and experience as well as its boundary-defining capacity.
The purpose of the study was to introduce the concept of distributed leadership to international nursing management by conducting a cross-national investigation of its relationships with empowering nursing leadership, nurses' work self-efficacy and nurses' innovative behaviour.
Distributed leadership theory suggests that when more people lead processes together, innovation will be superior to solo leadership. However, we need knowledge about how nurse managers may enhance nurses' distributed leadership agency (DLA), and whether such results are generalizable across countries.
The cross-national survey with an overall purposeful sampling method used questionnaire data from hospital nurses from Israel (n=239), Italy (n=226) and Denmark (n=709). We used validated scales measuring Empowering Leadership, Self-efficacy, Innovative Work Behavior and DLA.
The results from all three countries showed that empowering leadership and work self-efficacy were positively related to DLA, which, in turn, was also related to more innovation.
