2%) and the proportion of frail individuals with HF was 31% (95% CI = 17-45; I2 = 98.7%). selleck inhibitor Two studies using the same frailty definition reported estimates for the association between frailty and HF (pooled OR = 3.44; 95% CI = 0.75-15.73; I2 = 95.8%). In conclusion, frailty and pre-frailty are frequent in people with HF. Persons with HF have 3.4-fold increased odds of frailty. Longitudinal studies examining bidirectional pathophysiological pathways between HF and frailty are needed to further clarify this relationship and to assess if specific treatment for HF may prevent or delay the onset of frailty and vice versa. V.BACKGROUND Studies of long-term inotrope use in advanced HF have previously provided limited and conflicting results. This study aimed to evaluate the safety and efficacy of long-term milrinone use and identify predictors of failure to bridge to orthotropic heart transplant (OHT) in a cohort of end-stage heart failure (HF) patients listed for heart transplantation and receiving inotrope therapy. METHODS The study included 150 adults listed for OHT at a single center from 2001 to 2017 who received milrinone therapy for ≥30 days. Multivariate Cox proportional hazards models were used to identify factors associated with "failure" (left ventricular assist device, intra-aortic balloon pump, status downgrade due to instability, death) vs. "success" (OHT, recovery) during bridging to OHT. RESULTS "Failure" occurred in 33 (22%) patients. Factors independently associated with failure included male sex (HR = 7.6; p = 0.004), no implantable cardioverter-defibrillator (HR = 3.8; p = 0.009), and lack of guideline-directed medical therapy (GDMT) with a beta-blocker (HR = 7.8; p = 0.002) or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (HR = 6.3; p less then 0.001). Patients who received fewer guideline-directed medications had a higher cumulative probability of failure. Adverse events included central line-associated bloodstream infection (2.55 per 1000 line-days) and arrhythmia (1.59 per 1000 treatment-days). CONCLUSIONS Our findings suggest that long-term milrinone therapy in selected patients is associated with a high rate of successful bridging to OHT and a low rate of adverse events. Patients intolerant of GDMT are more likely to fail to bridge to OHT without mechanical support. Sex differences in outcomes associated with milrinone therapy should be explored. Ambient PM2.5 was collected during the winter season from Taiyuan, Shanxi, China; Jinan, Shandong, China; and Sacramento, California, USA, and used to create PMSX, PMSD, and PMCA extracts, respectively. Time-lag experiments were performed to explore the in vivo and in vitro toxicity of the PM extracts. In vivo inflammatory lung responses were assessed in BALB/C mice using a single oropharyngeal aspiration (OPA) of PM extract or vehicle (CTRL) on Day 0. Necropsies were performed on Days 1, 2, and 4 post-OPA, and pulmonary effects were determined using bronchoalveolar lavage (BAL) and histopathology. On Day 1, BAL neutrophils were significantly elevated in all PM- versus CTRL-exposed mice, with PMCA producing the strongest response. However, histopathological scoring showed greater alveolar and perivascular effects in PMSX-exposed mice compared to all three other groups. By Day 4, BAL neutrophilia and tissue inflammation were resolved, similar across all groups. In vitro effects were examined in human HepG2 hepatocytes, and U937 cells following 6, 24, or 48 hours of exposure to PM extract or DMSO (control). Luciferase reporter and quantitative polymerase chain reaction assays were used to determine in vitro effects on aryl hydrocarbon receptor (AhR) activation and gene transcription, respectively. Though all three PM extracts activated AhR, PMSX produced the greatest increases in AhR activation, and mRNA levels of cyclooxygenase-2, cytochrome P450, interleukin (IL)-8, and IL-1β. These effects were assumed to result from a greater abundance of polycyclic aromatic hydrocarbons (PAHs) in PMSX compared to PMSD and PMCA. V.Oxidative stress is defined as an imbalance between the production and elimination of reactive oxygen species (ROS) are associated with various inflammation-related human disease. ROS can oxidize lipids, which subsequently undergo fragmentation to produce F2-isoprostanes (F2-IsoPs). Eight-isoprostane is one of the most extensively studied F2-IsoPs and the most commonly used biomarker for the assessment of oxidative stress in human studies. This urinary biomarker is quantified using either chemical or immunological techniques. A "physiological" range for 8-isoprostanes is needed to use this biomarker as a measure of excess oxidative stress originating from occupational exposures. However, ranges reported in the literature are inconsistent. We designed a standardized protocol of a systematic review and meta-analysis to assess baseline values for 8-isoprostane concentrations in urine of healthy adults and identify determinants of their inter- and intra-individual variability. We searched PubMed from journal incentrations in spot urine with creatinine, quantifying 8-isoprostane with chemical analytical methods, and reporting results as median and quartiles. This will help in comparing results across studies. Perfluorooctanoic acid (PFOA) is a persistent organic pollutant prevalent in the environment and implicated in damage to the liver leading to a fatty liver phenotype called hepatocellular steatosis. Our goal is to provide a basis for PFOA-induced hepatocellular steatosis in relation to epigenetic alterations and mRNA splicing. Young adult female mice exposed to different concentrations of PFOA showed an increase in liver weight with decreased global DNA methylation (5-mC). At higher concentrations, the expression of DNA methyltransferase 3A (Dnmt3a) was significantly reduced and the expression of tet methycytosine dioxygenase 1 (Tet1) was significantly increased. There was no significant change in the other Dnmts and Tets. PFOA exposure significantly increased the expression of cell cycle regulators and anti-apoptotic genes. The expression of multiple genes involved in mTOR (mammalian target of rapamycin) signaling pathway were altered significantly with reduction in Pten (phosphatase and tensin homolog, primary inhibitor of mTOR pathway) expression.
