But, CURB-65 found (OR 2.968 and 2.284, respectively) superior to others in predicting 30 and 90-days mortality.Conclusions CURB-65 score is a significant, simple and feasible score for predicting 30 and 90 days mortality in COPD exacerbation and may be routinely used in all patients hospitalized with COPD exacerbation.

Dyslipidemia is a common condition that increases the risk of heart diseases and stroke. High levels of low-density lipoprotein-cholesterol (LDL-C) are correlated with a higher risk for heart disease. A drug class known as 'statins' is the gold standard for LDL-C-lowering, but its use in some patients is limited by its adverse effects of myalgias and myopathies. Use of other LDL-C-lowering agents is frequently limited by cost and degree of efficacy. Additionally, many high-risk atherosclerotic cardiovascular disease patients fail to meet LDL-C goals despite maximally tolerated statin therapy with or without the addition of a non-statin agent.

This review covers the pharmacology, pharmacokinetics, clinical trials, and clinical implications of bempedoic acid. A PubMed search was conducted using the terms bempedoic, bempedoic acid, Nexletol, ETC-1002, and adenosine triphosphate citrate lyase inhibitor. Additional data were obtained from the prescribing information and relevant guidelines. All clinical trials were included.

Bempedoic acid has not been shown to cause myalgias or myopathies and is likely to be competitively affordable compared to other LDL-C-lowering agents. Bempedoic acid has been shown to be superior compared to placebo and provides additional LDL-C lowering on top of maximally tolerated statin therapy or combined with ezetimibe alone.

Germline heterozygous IKZF1 mutations have been described in primary immunodeficiency as well as in human hematologic malignancies, affecting both B and T cells. Depending on the allelic variants of IKZF1 mutations (haploinsufficiency and dominant negative) clinical phenotypes vary from bacterial, viral, or fungal infection to autoimmune disease and malignancy.Areas covered In this review, the authors provide an overview of genotype-phenotype correlation and clinical manifestations in patients with IKZF1 mutations. The importance of accurate diagnosis and monitoring immunological changes is also discussed for the management of these complex and rare diseases. IKZF1/IKAROS, immunodeficiency, and CVID were used as the search terms in PubMed and Google Scholar.Expert opinion Over the past 5 years both genetic and molecular studies have unveiled surprisingly diverse roles of IKZF1 mutations in primary immunodeficiency. While an increasing number of novel IKZF1 variants are being reported, limited, and complex laboratory testing is necessary to verify the mutation's pathogenicity. Therefore, the combination of understanding mechanistic concepts and clinical and immunological follow-up is necessary to increase our knowledge of IKAROS-associated diseases.The current study tested a theoretical account of how and when norms message features influence attitudes and intentions. Specifically, we examined whether functional matching and numeracy help to explain variation in persuasive outcomes following exposure to norms messaging. We executed two experiments to test our functional matching and numeracy assumptions in the context of alcohol consumption. Across both studies, our functional matching assumption was not supported. In Study 2, numeracy moderated the impact of descriptive norms message content on intentions to engage in heavy drinking, such that message exposure was associated with reduced drinking intentions among participants with greater levels of numeracy. In sum, the findings provided some evidence that the functional attitude approach lacked theoretical utility and that numeracy dictated the effect of norms message exposure on intentions.Purpose MicroRNA-151b (miR-151b) showed altered expression in ovariectomized rat model of osteoporosis. This study established an ovariectomy-induced osteoporotic rat model to investigate the role of miR-151b in osteoblasts.Methods Eighteen female Sprague-Dawley (SD) rats were divided randomly into Sham and OVX group (n = 9). The transfections with different miRNAs and expression vectors were confirmed by RT-qPCR. The protein expression of Msx2 was detected by Western blots. The interaction between miR-151b and Msx2D was evaluated by RNA pull-down and dual luciferase reporter assay.Results The expression of miR-151b was significantly increased in femoral tissues of ovariectomy-induced osteoporotic rats. The expression of osteogenesis marker genes including RUNX2, ALP, OCN, OSX, and Msx2 were all significantly increased in osteogenic medium (OM) incubated primary osteoblasts and MC3T3-E1 cells. The interaction between miR-151b and Msx2 was confirmed by luciferase reporter assay and RNA pull-down. Moreover, overexpression of miR-151b significantly inhibited Msx2 in both MC3T3-E1 cells and primary osteoblasts, while miR-151b inhibitor had the opposite effect on the expression of Msx2. In addition, in primary osteoblasts and MC3T3-E1 cells, miR-151b overexpression, or Msx2 silence significantly decreased the expression of OSX, ALP, RUNX2, and OCN.Conclusion MiR-151b could inhibit osteoblast proliferation, differentiation, and mineralization via downregulating Msx2 in both MC3T3-E1 cells and primary osteoblasts. MiR-151b might serve as a novel therapeutic target for osteoporosis.Abbreviations miR-151b microRNA-151b; miRNAs microRNAs; Msx2 Msh homeobox 2; MAPK mitogen-activated protein kinase; STAT signal transducer and activator of transcription; SD Sprague-Dawley; BMD bone mineral density; qRT-PCR quantitative reverse transcription PCR; MTT methyl thiazolyl tetrazolium; OVX ovariectomy; ALP alkaline phosphatase.Growing emphasis on exploring the antiproliferative potential of natural compounds has gathered momentum for the formulation of anticancer drugs. In the present study, the anticancer and apoptotic potential of glycyrrhizin (GLY) was studied on HPV- C33A cervical cancer (CCa) cells. Our results indicated that GLY exerted antiproliferative effects in the C33A cells by inducing significant cytotoxicity. Treatment with GLY substantially increases the apoptosis in a dose-dependent manner via disrupting the mitochondrial membrane potential. GLY induced apoptosis in C33A cells via activation of capsase-9 (intrinsic pathway) and caspase-8 (extrinsic pathway) along with the modulation of pro- and antiapoptotic protein expression. Moreover, GLY also exerted cell cycle arrest in C33A cells at G0/G1 phase which was associated with the decreased expression of cyclin D1 and cyclin-dependent kinase 4 (CDK4) along with the increased expression of CDK inhibitor p21Cip1. Furthermore, GLY treated CCa cells exhibited significant downregulation of Notch signaling pathway which may be associated with increased apoptosis as well as cell cycle arrest in C33A CCa cells. Thus, GLY could be an appendage in the prevention and management of CCa.Background Currently, colistin-resistant pathogens emerged has become a global health concern. This study assessed the distribution of mcr-1 to mcr-5 variants with the phenotypic colistin-resistance in bacterial isolates from urinary tract infection (UTI) patients in Bangladesh.Methods A cross-sectional study was conducted between April 2017 and March 2018 to enroll uncomplicated UTI patients, and 142 urine samples were analyzed. Uropathogens were identified using the API-20E biochemical panel and 16s rRNA gene sequencing. Polymerase chain reactions detected the mcr gene variants in the UTI isolates. The phenotypic colistin-susceptibility was determined by the Kirby-Bauer disc-diffusion method and the minimal inhibitory concentration (MIC) measurement.Results The combined carriage of mcr-1 and mcr-2 genes in 11.4% (14/123) of urinary tract pathogens. The mcr-positive pathogens include five Escherichia coli, three Klebsiella pneumoniae, three Pseudomonas putida, two Enterobacter cloacae, and one Enterobacter hormaechei. The mcr-positive variant showed significantly higher phenotypic colistin resistance with MIC between >16 µg/mL and >128 µg/mL (p less then 0.001). Over 85% of colistin-resistant isolates showed MDR phenomena.Conclusions The emergence of the clinical MDR pathogens with resistance to a highly selective drug may lead to a lack of treatment options for the infectious diseases and spread of infection to the unaffected cohorts.IntroductionNuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway plays a key role in diverse gene expressions responsible for protection against oxidative stress and xenobiotics. Chalcones with a common chemical scaffold of 1,3-diaryl-2- propen-1-one, are abundantly present in nature with a wide variety of pharmacological properties. This review will discuss the interactions of natural and synthetic chalcones with Nrf2 signaling.Areas coveredChalcones are reportedly found to activate Nrf2 signaling pathway, expression of Nrf2-regulated antioxidant genes, induce cytoprotective proteins and upregulate multidrug resistance-associated proteins. Chalcones being soft electrophiles are less prone to hostile off-target effects and unlikely to induce carcinogenicity and mutagenicity. Furthermore, their low toxicity, structural diversity, feasibility in structural reorganization and the presence of α,β-unsaturated carbonyl group which makes them suitable drug candidates targeting Nrf2-dependent diseases.Expert opinionNrf2-Keap1 signaling pathway plays a central role in redox signaling. However, available therapeutic agents for Nrf2 activation have limited practical applications due to their associated risks, relatively low efficacy and bioavailability. The designing and fabrication of new chemical entities with chalcone scaffold-based Michael acceptor mechanism should be aimed as potential therapeutic Nrf2 activators to target oxidative stress and inflammation-mediated diseases such as atherosclerosis, Parkinson's disease and many more.

Pre-exposure prophylaxis with a single daily pill of emtricitabine (F) plus tenofovir disoproxil fumarate (TDF) is highly efficacious at preventing HIV acquisition. find more Tenofovir alafenamide (TAF) is another tenofovir prodrug that delivers higher intracellular levels of active tenofovir diphosphate in blood cells and has an improved safety profile compared to TDF. Given the recent regulatory approval of the F/TAF combination for prophylaxis, it is important to review its safety and efficacy.

In this review, the author examines the safety and efficacy of F/TAF for pre-exposure prophylaxis. Both published manuscripts and conference papers are reviewed. F/TAF is non-inferior to F/TDF at preventing HIV acquisition in men and transgender women with a trend toward superiority. F/TAF has yet to be tested against HIV exposure via injection or vaginal intercourse.

Within these limitations, F/TAF may be particularly advantageous for older individuals thanks to improved kidney safety compared to F/TDF. F/TAF did not possess the hypolipidemic properties of F/TDF and was associated with weight gains.
