BACKGROUND Mounting epidemiologic studies have investigated the potential inverse association between Mediterranean diet (MD) adherence and colorectal cancer (CRC) incidence and mortality. OBJECTIVES This meta-analysis aimed to investigate the association between MD adherence and CRC incidence and mortality. METHODS PubMed, Embase, and Web of Science were searched to identify eligible studies through September 2019. A random-effects model was used to estimate summary RRs and 95% CIs. RESULTS This meta-analysis included 13 prospective cohort studies, of which 9 reported CRC incidence and 5 reported CRC mortality. The summary RR of CRC incidence was 0.90 (95% CI 0.84, 0.96) for highest compared with lowest MD adherence and 0.96 (95% CI 0.94, 0.99) per 2-score increase in MD adherence. The summary RRs for highest compared with lowest MD adherence were 0.82 for rectal cancer (95% CI 0.71, 0.95), 0.94 for proximal colon cancer (95% CI 0.87, 1.02), and 0.91 for distal colon cancer (95% CI 0.79, 1.04). Neither the summary HR of overall mortality for highest compared with lowest pre- and postdiagnosis MD adherence, nor the summary HR of CRC-specific mortality for highest compared with lowest prediagnosis MD adherence achieved a value with statistical significance. CONCLUSIONS Our meta-analysis supports the inverse association of MD adherence with CRC incidence, but not with overall mortality or CRC-specific mortality among those diagnosed with CRC.

Polymorphisms of the ESR1 gene and the ESR2 gene have been identified as risk factors for URSA, but with varied associations in Chinese populations. This study aimed to compare the role of gene polymorphisms of ESR1 and ESR2 and the risk of URSA in the Chinese Hui and Chinese Han populations. MATERIAL AND METHODS Chinese Hui women (n=171) and Chinese Han women (n=234) with URSA were compared with healthy controls (n=417) matched by ethnicity and age. Genotyping was performed using direct sequencing and identified three polymorphisms of the ESR1 gene (rs9340799, rs2234693, and rs3798759) and three polymorphisms of the ESR2 gene (rs207764, rs4986938, and rs1256049). The association between ESR1 and ESR2 gene polymorphisms and the risk of URSA was evaluated statistically using the odds ratio (OR) and 95% confidence interval (CI). RESULTS No association was detected between the allelic, dominant, and recessive models of ESR1 and ESR2 gene polymorphisms and the risk of URSA in Chinese Han and Hui populations (p>0.05). The distribution of the AGT haplotype containing ESR2 gene polymorphisms rs2077647A, rs4986938G, and rs1256049T was significantly reduced in patients with URSA compared with controls in the Chinese Hui population (OR, 0.29; 95% CI, 0.14-0.62; p=0.0009; padj=0.005). CONCLUSIONS The AGT haplotype of the ESR2 gene containing the polymorphism rs2077647A, rs4986938G, and rs1256049T (ESR2 hapAGT) was a protective factor for URSA in women in the Chinese Hui population when compared with the Chinese Han population.Immunotherapy based on immune checkpoint inhibitors (ICIs) is currently broadly used in the treatment of different types of cancer. The treatment targeting programmed cell death protein 1/programmed death-ligand 1 axis is already approved by Food and Drug Administration for numerous cancers. These kinds of therapy brought spectacular results in the treatment of non-small cell lung cancer where systemic therapy was ineffective. However, a wide range of applied therapies based on ICIs in the clinic have led to unexpected side effects, such as severe cardiotoxicity. It needs to be underlined that the molecular mechanism of myocarditis in response to ICIs is still not fully understood. Lack of sufficient knowledge, especially concerning the kind of risk factors increasing probability of myocarditis, poses currently a large clinical problem. Continuous cardiac monitoring of patients who undergo ICI treatment presents another problem as it is cost-ineffective for the healthcare system. Herein, we highlight the risks of use of anticancer therapy based on ICIs. We also stress that detailed monitoring of any event of cardiotoxicity following ICIs treatment should be carefully investigated and registered to give a global overview of the frequency of myocarditis occurrence. Moreover, we propose that the extension of molecular and systemic knowledge of etiology of myocarditis as a side effect, including the role of protein kinases, will be highly beneficial for the medical field. Last but not least, better understanding of mechanisms of cardiotoxicity induction will improve the safety of cancer patients and will help clinicians in prediction of unexpected side effect occurrence. © 2020 International Union of Biochemistry and Molecular Biology.BACKGROUND Incidence of oropharyngeal cancer (OPC) is expected to increase but its health care cost is unknown. The purpose for this study was to estimate the phase-specific lifetime health care costs of OPC for commercially insured individuals in the United States. METHODS We used the Truven MarketScan Commercial Claims and Encounter Database to identify our patient population. Cox survival analysis was used to estimate patients' monthly survival probabilities. We determined the ratios of the cumulative costs up to a particular survival probability and the costs from that time point to death for all subjects who died before end of the 5-year follow-up period. This relationship was then used to predict phase-specific lifetime health care costs. RESULTS Our study included 2445 patients with OPC. this website The predicted phase-specific lifetime health care costs attributable to OPC were $88 872, $24 038, and $1537 in the initial, continuous, and terminal phases, respectively, among commercially insured patients. © 2020 Wiley Periodicals, Inc.An analysis is presented of four short-term retrieved highly crosslinked polyethylene (HXLPE) hip liners grafted with 2-methacryloyloxyethyl phosphorylcholine (MPC) on their bearing surfaces, which were recently commercialized as a new generation of artificial hip joints. Straightforward evidences by X-ray photoelectron spectroscopy (XPS) confirmed that the MPC layer peeled off on the bearing surface of all short-term liners in both main wear and nonwear zones. Analyses by Fourier-transform infrared spectroscopy with attenuated total reflection assessed the extent of surface oxidation and revealed the type of oxidative species. Electron spin resonance analyses, which compared retrievals and as-received samples, revealed the presence of different species of alkoxyl CO• radicals. This study suggests that MPC grafts on polyethylene do not offer any additional protection from oxidation and can delaminate prematurely after short-term in vivo exposure. © 2020 Wiley Periodicals, Inc.
