Functional contributions of individual cellular components of the bone-marrow microenvironment to myelofibrosis (MF) in patients with myeloproliferative neoplasms (MPNs) are incompletely understood. We aimed to generate a comprehensive map of the stroma in MPNs/MFs on a single-cell level in murine models and patient samples. Our analysis revealed two distinct mesenchymal stromal cell (MSC) subsets as pro-fibrotic cells. MSCs were functionally reprogrammed in a stage-dependent manner with loss of their progenitor status and initiation of differentiation in the pre-fibrotic and acquisition of a pro-fibrotic and inflammatory phenotype in the fibrotic stage. The expression of the alarmin complex S100A8/S100A9 in MSC marked disease progression toward the fibrotic phase in murine models and in patient stroma and plasma. Tasquinimod, a small-molecule inhibiting S100A8/S100A9 signaling, significantly ameliorated the MPN phenotype and fibrosis in JAK2V617F-mutated murine models, highlighting that S100A8/S100A9 is an attractive therapeutic target in MPNs.Kidney disease is poorly understood because of the organ's cellular diversity. We used single-cell RNA sequencing not only in resolving differences in injured kidney tissue cellular composition but also in cell-type-specific gene expression in mouse models of kidney disease. This analysis highlighted major changes in cellular diversity in kidney disease, which markedly impacted whole-kidney transcriptomics outputs. Cell-type-specific differential expression analysis identified proximal tubule (PT) cells as the key vulnerable cell type. Through unbiased cell trajectory analyses, we show that PT cell differentiation is altered in kidney disease. Metabolism (fatty acid oxidation and oxidative phosphorylation) in PT cells showed the strongest and most reproducible association with PT cell differentiation and disease. Coupling of cell differentiation and the metabolism was established by nuclear receptors (estrogen-related receptor alpha [ESRRA] and peroxisomal proliferation-activated receptor alpha [PPARA]) that directly control metabolic and PT-cell-specific gene expression in mice and patient samples while protecting from kidney disease in the mouse model.We conducted the first scoping literature review on ART uptake and adherence among Female Sex Workers (FSW), following PRISMA-ScR guidelines. Searches were conducted in PubMed, Embase, CINAHL, PsycInfo, and Sociological Abstracts. Eligibility criteria included reporting an ART uptake or adherence result among FSW aged 18 or older; peer-reviewed; published in English between 1996 and 2018. Our search identified 6,735 studies; 30 met eligibility requirements. ART uptake ranges from 0 to 100% and adherence ranges from 50-90%, depending on measurement methods. Uptake and adherence influencing factors are mapped onto a social ecological model (SEM). Knowledge and beliefs, substance use, food insecurity and sex-work engagement were negatively associated, while older age, relationships and social support were positively associated with ART uptake and adherence. Standardised methods to measure uptake and adherence prevalence must be established for data comparison. Evidence regarding ART uptake and adherence barriers and facilitators span multiple SEM levels, although more research is needed regarding structural and occupational level influencers. Results suggest that the multi-level ART uptake and adherence barriers faced by FSW require complex multi-level evidence-based interventions. Study findings can inform ART interventions, future research, and offer guidance to other support services with FSW, such as PrEP interventions.This study uses a new approach for the recycling of plant nutrients by co-digesting sewage sludge with fly ash from a wood combustion. Selleck ABT-869 Sewage sludge and fly ash both are enriched with nutrients of the wastewater resp. wood, which makes these products an enhanced source for recycled fertilizers. The effects of the ash addition to the anaerobic digestion are studied in several lab scale experiments including effects on the gas production and microbial activity. Following that, the fertilizing qualities of the digestate are evaluated by plant growth experiments. The results show that the fertilizing qualities of the digested sludge were improved by the ash addition. Next to this, gas production results show that the methane production was not affected by the ash addition, while the total gas release was reduced. The sulphur addition by the ash stimulated sulphate reducing bacteria. The sulphate reducing bacteria did not markedly inhibit the methanogens.Based on a brief examination of private sector healthcare in Bangladesh, this article examines two questions (a) the compatibility of social justice and the right to healthcare with the private provision of healthcare, (b) the implication of the private sector's role in realising social justice and the right to healthcare. It is based on an extensive review of both published and unpublished documents including journal articles, government reports, policy and planning documents, as well as reports of United Nations, the World Health Organisation and the World Bank. Different search engines and databases were used to collect the documents. Thematic data analysis techniques were used in developing the text. Private provision of healthcare services raises concerns about social justice and the right to healthcare. This sector to some extent is unable to fulfil its obligation to realise social justice and the right to healthcare in the provision of healthcare. An expanding private sector role creates complexities in promoting and protecting the right to health and social justice. The study emphasised the role of the government to engage its political will and make changes in policy and governance to engage private sector in realising right to healthcare and social justice.Advanced prostate cancer is a continuum of states distinguished by the presence or absence of metastasis and sensitivity or resistance to androgen deprivation therapy (ADT). Therapeutic options for this disease continue to rapidly evolve, making it a challenge to apply results of clinical trial data to daily patient management. One question relevant to providers is whether molecular biomarkers predictive of response or resistance to therapies are available to guide clinical treatment decisions. Other salient topics include the timing of therapy initiation in patients with biochemical recurrence, treatment approach in low-volume versus high-volume metastatic castrate-sensitive prostate cancer, types of agents available beyond ADT, and timing of their use in men with nonmetastatic castrate-resistant prostate cancer as well as whether sequencing of therapies in metastatic castrate-resistant prostate cancer matters. Additionally, familiarity with emerging treatment strategies is important. This review addresses the gray areas and challenging questions in advanced prostate cancer management that frequently arise in clinical practice.
