Inflammation and oxidative stress contribute to the initiation and progression of septic lung injury. MicroRNA-217 (miR-217) is proved to be involved in controlling inflammatory response and oxidative stress, yet its role and underlying mechanism in the pathogenesis of septic lung injury remain elusive. Caecal ligation and puncture surgery were performed to generate sepsis in vivo and mice were kept for 12 h to imitate septic lung injury. Next, mice were administrated with miR-217 antagomir or agomir to decrease or increase the expression of miR-217 in lung tissue. Moreover, primary peritoneal macrophages were separated and incubated with lipopolysaccharide (LPS) to further verify the role of miR-217 in vitro. miR-217 was upregulated in septic lungs and primary macrophages. miR-217 antagomir alleviated, whereas miR-217 agomir aggravated inflammation and oxidative stress in septic mice and LPS-stimulated macrophages. Further detection identified SIRT1 was responsible for miR-217 antagomir-mediated anti-inflammatory and anti-oxidant effects, and SIRT1 inhibition abolished the beneficial effects of miR-217 antagomir in vivo and in vitro. Our data defined miR-217 as a therapeutic target for treating septic lung injury.Aim This study examined treatment patterns and effectiveness outcomes of patients with metastatic triple-negative breast cancer (mTNBC) from US community oncology centers. Materials & methods Eligible patients were females, aged ≥18 years, diagnosed with mTNBC between 1 January 2010 and 31 January 2016. Kaplan-Meier and Cox regression methods were used. Results Sample comprised 608 patients with average age of 57.5 years and 505/608 patients (83.1%) received systemic treatment. Overall survival (OS) from first-line treatment found that African-American patients had shorter OS than White (9.3 vs 13.7 months; hazard ratio 1.35; p = 0.006). this website Conclusion More than 15% of women with mTNBC were not treated, indicating a high unmet need. Overall prognosis remains poor, which highlights the opportunity for newer therapies to improve progression-free survival and OS.Circulating cystatin C level has been identified as a predictor of adverse outcomes in patients with coronary artery disease (CAD). This meta-analysis aimed to investigate the value of circulating cystatin C level for predicting adverse outcomes in patients with acute coronary syndrome (ACS). We comprehensively searched articles indexed in Pubmed and Embase databases from their inceptions to 30 November 2019. All available observational studies that investigated the association between circulating cystatin C level and major adverse cardiovascular events [MACE] (including death, heart failure, re-infarction, target vascular revascularization, angina and stroke) or all-cause mortality in patients with ACS were included. The prognostic value was expressed by pooling the multivariable-adjusted hazard risk (HR) with 95% confidence interval (CI) for the highest versus the lowest category of cystatin C level. Eleven eligible studies (12 articles) with 4600 ACS patients were identified. Meta-analysis indicated that the highest versus lowest category of cystatin C level was associated with higher risk of MACE (HR 2.28; 95% CI 1.92-2.71) and all-cause mortality (HR 2.89; 95% CI 1.43-5.83) after adjustment for estimated glomerular filtration rate (eGFR) or creatinine. Subgroup analysis by subtypes of patients, study design, follow-up duration and cutoff level of cystatin C further confirmed the value of cystatin C level for predicting MACE. Elevated circulating cystatin C level at baseline is strongly and independently associated with an increased risk of MACE and all-cause mortality in patients with ACS. Determination of circulating cystatin C level has potential to improve risk stratification of ACS patients.

Knowledge regarding antidiabetic medication (ADM) use prior to breast cancer (BC) diagnosis remains limited. The objectives were to (1) evaluate if the prior use of ADM was associated with BC stage at diagnosis and (2) identify and compare patient characteristics among BC patients using different ADMs.

Newly diagnosed female BC patients exposed to any medication during one year prior to cancer diagnosis were identified in 2008-2013 Linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Stage at diagnosis, categorized as early and advanced, was the primary outcome. Chi-square tests were used to compare characteristics and logistic regression models were applied to examine the effect while controlling for patient's characteristics.

A total of 1,719 female BC patients used ADM while 6,084 patients were non-ADM users. Although a higher proportion of ADM users (20.36%) were diagnosed with advanced stage compared to the non-ADM users (14.46%), the difference was not statistically significant after adjusting for the patients' characteristics. Besides, insulin users were more likely to be diagnosed with advanced stage (adjusted odds ratio 1.69; 95% CI 1.15, 2.48) compared to metformin users.

The association between ADM use and BC diagnostic characteristics varied based on different treatments.

Recent pharmacological studies on the plant have highlighted M. ferrea to be a rich source of secondary metabolites, with proven therapeutic applications. Since the toxicity of a plant following repeated exposure is of higher clinical significance, the present investigation was conducted to establish the subacute toxicity profile of the ethanolic extract of Mesua ferrea flowers (MFE). The study was conducted in accordance with the OECD Guideline 407, wherein MFE was administered orally to groups of male and female rats (n = 5/group/sex) at the doses of 100, 500 and 1000 mg/kg, over a period of 28 days. Repeated administration of MFE had no adverse effect on the growth rate and hematological parameters of the animals. There were no changes in the biochemical parameters, except for a slight decrease in the CHOL (total cholesterol) levels, and an increase in the levels of AST (aspartate aminotransferase) and ALT (alanine aminotransferase), at the highest dose.
