ch patients may be important in reducing overall mortality of COVID-19.
The incidence of altered mentation or stroke on admission predicts a modest but significantly higher risk of in-hospital mortality independent of disease severity. While other biomarker factors also predict mortality, measures to identify and treat such patients may be important in reducing overall mortality of COVID-19.The fungus Paracoccidioides is a prevalent human pathogen endemic to South America. The genus is composed of five species. In this report, we use 37 whole-genome sequences to study the allocation of genetic variation in Paracoccidioides We tested three genome-wide predictions of advanced speciation, namely, that all species should be reciprocally monophyletic, that species pairs should be highly differentiated along the whole genome, and that there should be low rates of interspecific gene exchange. We find support for these three hypotheses. Species pairs with older divergences show no evidence of gene exchange, while more recently diverged species pairs show evidence of modest rates of introgression. Our results indicate that as divergence progresses, species boundaries become less porous among Paracoccidioides species. Our results suggest that species in Paracoccidioides are at different stages along the divergence continuum.IMPORTANCE Paracoccidioides is the causal agent of a systemic mycosis in Latin America. Most of the inference of the evolutionary history of Paracoccidioides has used only a few molecular markers. In this report, we evaluate the extent of genome divergence among Paracoccidioides species and study the possibility of interspecific gene exchange. We find that all species are highly differentiated. BMS-986365 cost We also find that the amount of gene flow between species is low and in some cases is even completely absent in spite of geographic overlap. Our study constitutes a systematic effort to identify species boundaries in fungal pathogens and to determine the extent of gene exchange among fungal species.Amikacin and colistin are effective against carbapenem-resistant Klebsiella pneumoniae In 2017, we successively isolated three carbapenem-resistant K. pneumoniae isolates (ST967) from a patient with chronic renal failure in Japan. The first (SMKP01, sputum, day 0) and second (SMKP02, blood, day 14) strains were resistant to most antimicrobials tested but still susceptible to amikacin (MICs of 4 and 0.5 mg/liter, respectively) and colistin (MIC of 0.5 mg/liter for both). The third strain (SMKP03, blood, day 51) was not susceptible to amikacin (MIC, 32 mg/liter), and its MIC for colistin varied (0.5 to 8 mg/liter). Whole-genome sequencing of SMKP01 revealed that 17 of 20 antimicrobial resistance genes, including qnrB91 (a novel qnrB2 variant) and aac(6')-Ib-cr, were located on an 86.9-kb IncFII-IncQ plasmid. The qnrB91 conferred greater fluoroquinolone resistance than qnrB2 SMKP03 aac(6')-Ib-cr that possessed a gene mutation that resulted in an R102W substitution, namely, aac(6')-Ib-D179Y, made a greater contriesistance and novel antimicrobial resistance genes in the clinical isolates, the identity of the bacterial factor(s) that generate this emergence is still unclear. We report that a disruptive mutation in MutS, arising during the clinical course of an infection, created a context for the acquisition of colistin resistance and the emergence of a novel variant of the amikacin resistance gene in multidrug-resistant K. pneumoniae via an increase in the frequency of spontaneous mutation. This observation is important for understanding how K. pneumoniae develops multidrug resistance during infection and could potentially lead to new antimicrobial treatments for high-risk pathological microbes.Since its introduction in the 1980s, futility as a concept has held contested meaning and applications throughout medicine. There has been little discussion within the psychiatric literature about the use of futility in the care of individuals experiencing severe and persistent mental illness (SPMI), despite some tacit acceptance that futility may apply in certain cases of psychiatric illness. In this paper, we explore the literature surrounding futility and argue that its connotation within medicine is to describe situations where patients (or their substitute decision-makers) believe that interventions will almost certainly provide no meaningful benefit. We then provide two arguments in support of the use of futility within the care of individuals experiencing SPMI that some SPMI can be considered a terminal illness, and that the risk-benefit ratio is a dynamic entity such that futility can help describe what Gillett calls the 'risk of unacceptable badness' when it comes to considering how an intervention might impact a patient's quality of life. We posit that capacity should not pose an obstacle to declaring futility when caring for individuals experiencing SPMI and explain how futility is not antithetical to recovery in mental health. Finally, we describe how using futility within psychiatric practice can allow for a reorientation of care by signalling the need to shift to a palliative approach.Although frequently associated with tumor progression, inflammatory cytokines initially restrain transformation by inducing senescence, a key tumor-suppressive barrier. Here, we demonstrate that the inflammatory cytokine, oncostatin M, activates a mesenchymal/stem cell (SC) program that engages cytokine-induced senescence (CIS) in normal human epithelial cells. CIS is driven by Snail induction and requires cooperation between STAT3 and the TGFβ effector, SMAD3. Importantly, as cells escape CIS, they retain the mesenchymal/SC program and are thereby bestowed with a set of cancer SC (CSC) traits. Of therapeutic importance, cells that escape CIS can be induced back into senescence by CDK4/6 inhibition, confirming that the mechanisms allowing cells to escape senescence are targetable and reversible. Moreover, by combining CDK4/6 inhibition with a senolytic therapy, mesenchymal/CSCs can be efficiently killed. Our studies provide insight into how the CIS barriers that prevent tumorigenesis can be exploited as potential therapies for highly aggressive cancers.
