We put forward the hypothesis that there would be an inverse correlation between the activation threshold of the cellular stress responses (CSRs) and the risk of cancer, so that species or individuals with low-threshold CSRs will display a higher incidence or risk of cancer.

The Canadian Cardiovascular Society (CCS) guidelines for patients undergoing non-cardiac surgery address the lack of standardized management for patients at risk of perioperative cardiovascular complications. Our interdisciplinary group evaluated the implementation of these guidelines.

We used an interrupted time series design to evaluate the effect of implementation of the CCS guidelines, using routinely collected hospital data. The study population consisted of elective, non-cardiac surgery patients who were i) inpatients following surgery and ii) age ≥ 65 or age 45-64 yr with a Revised Cardiac Risk Index ≥ 1. Outcomes included adherence to troponin I (TnI) monitoring (primary) and adherence to appropriate consultant care for patients with elevated TnI (secondary). Exploratory outcomes included cost measures and clinical outcomes such as length of stay.

We included 1,421 patients (706 pre- and 715 post-implementation). We observed a 67% absolute increase (95% confidence interval, 55 to 80; P < 0.001) in adherence to TnI testing following the implementation of the guidelines. In patients who had elevated TnI following guideline implementation (n = 64), the majority (85%) received appropriate follow-up care in the form of a general medicine or cardiology consult, all received at least one electrocardiogram, and half received at least one advanced cardiac test (e.g., cardiac perfusion scan, or percutaneous intervention).

Our study showed the ability to implement and adhere to the CCS guidelines. Large-scale multicentre evaluations of CCS guideline implementation are needed to gain a better understanding of potential effects on clinically relevant outcomes.

Among colorectal cancer (CRC) survivors, treatment for metastatic recurrence is most effective when malignancies are detected early through surveillance with carcinoembryonic antigen (CEA) level test and computer tomography (CT) imaging. However, utilization of these tests is low, and many survivors fail to meet the recommended guidelines. This population-based study assesses individual- and neighborhood-level factors associated with receipt of CEA and CT surveillance testing.

We used the Surveillance, Epidemiology and End Results (SEER)-Medicare data to identify Medicare beneficiaries diagnosed with CRC stages II-III between 2010 and 2013. We conducted multivariate logistic regression to estimate the effect of individual and neighborhood factors on receipt of CEA and CT tests within 18 months post-surgery.

Overall, 78% and 58% of CRC survivors received CEA and CT testing, respectively. We found significant within racial/ethnic differences in receipt of these surveillance tests. Medicare-Medicaid dual coverage was associated with 39% lower odds of receipt of CEA tests among non-Hispanic Whites, and Blacks with dual coverage had almost two times the odds of receiving CEA tests compared to Blacks without dual coverage.

Although this study did not find significant differences in receipt of initial CEA and CT surveillance testing across racial/ethnic groups, the assessment of the factors that measure access to care suggests differences in access to these procedures within racial/ethnic groups.

Our findings have implications for developing targeted interventions focused on promoting surveillance for the early detection of metastatic recurrence among colorectal cancer survivors and improve their health outcomes.

The relationship between the severity of NAFLD and extra-hepatic events such as cardiovascular disease (CVD), extra-hepatic cancer (EHC) or chronic kidney diseases (CKD) has not been clearly investigated in the general population.

The aim of this study was to assess whether the severity of fibrosis in NAFLD subjects was associated with extra-hepatic diseases based on noninvasive markers in a large population-based cohort.

The study population included a cohort of 118,664 participants from the nationwide CONSTANCES cohort. After excluding individuals with excessive alcohol consumption and other causes of liver disease, 102,344 were included. The noninvasive diagnosis of NAFLD and fibrosis was performed using a combination of the Fatty Liver Index (FLI) and the Forns Index. The history of CVD or EHC was recorded by a physician, and CKD was defined by a glomerular filtration rate < 60ml/mn.

The prevalence of NAFLD (FLI > 60) was 18.2%, 10% with mild fibrosis (Forns Index < 4.2), 7.7% with intermediate fibrosis (Forns Index 4.2-6.9), and 0.4% with advanced fibrosis (Forns Index > 6.9). FLT3-IN-3 datasheet The prevalence of CVD, EHC, or CKD increased significantly with the severity of fibrosis (p < 0.0001). When adjusted for demographic, metabolic risk factors, and smoking, NAFLD with intermediate or advanced fibrosis remained associated with CVD (OR 1.36, p < 0.0001 and OR 3.07, p < 0.0001, respectively), EHC (OR 1.24, p = 0.001 and OR 1.64, p = 0.004, respectively), and CKD (OR 1.18, p = 0.03 and OR 2.09, p < 0.0001, respectively).

In a large adult population-based cohort, there is a dose-dependent relationship between the severity of fibrosis and CVD, EHC, or CKD in NAFLD subjects.

The present study aimed to clarify how fluoride affected different differentiation stages of osteoblasts, and to elucidate the role of TGF-β1 in this process. We assessed cell migration, proliferation, DNA damage, and apoptosis of early-differentiated osteoblasts derived from bone marrow stem cells (BMSCs) exposed to fluoride with or without TGF-β1. Subsequently, MC3T3-E1 cells cultured with mineral induction medium were treated with fluoride to test fluoride's effect on late-differentiated osteoblasts. The specific fluoride concentrations and treatment times were chosen to evaluate the role of TGF-β1 in fluoride-induced osteoblastic differentiation and function. Results showed early-differentiated osteoblasts treated with a low dose of fluoride grew and moved more rapidly.
