Epidemiologic studies focusing on the association between 1-carbon metabolism-related vitamins (ie, folate, vitamin B6, vitamin B2, vitamin B12) and breast cancer risk have reported inconsistent findings. We conducted a systematic search of the reported data and performed a meta-analysis of prospective case-control and cohort studies to derive a more precise evaluation. The PubMed and EMBASE databases were searched to identify eligible studies. A total of 27 studies involving 49,707 cases and 1,274,060 individuals were included in the meta-analysis. The results indicated that a high intake of folate, vitamin B6, and vitamin B2 might decrease the risk of breast cancer. The corresponding pooled relative risks (RRs) for the highest intake compared with the lowest were 0.93 (95% confidence interval [CI], 0.88-0.99; P = .018), 0.94 (95% CI, 0.89-1.00; P = .037) and 0.90 (95% CI, 0.82-0.99; P = .026). No significant association between vitamin B12 and breast cancer risk was found (RR, 0.99; 95% CI, 0.94-1.04; P = .604). Further study showed that folate and vitamin B6 might decrease the risk of estrogen receptor-negative (ER-)/progesterone receptor-negative (PR-) breast cancer but not ER+/PR+ breast cancer. The dose-response meta-analysis indicated a significant linearity relationship between folate intake and a reduced risk of ER-/PR- breast cancer. An increment of folate intake (100 μg/d) corresponded to a 7% deceased risk of ER-/PR- breast cancer (RR, 0.93; 95% CI, 0.89-0.98; P = .007). In conclusion, a high intake of 1-carbon metabolism-related vitamins might contribute to the prevention of breast cancer, especially ER-/PR- breast cancer. Coronaviruses (CoVs) are a large family of viruses that cause disorders ranging from a mild cold to severe disease. Some of the CoVs are zoonotic, meaning they can be transmitted from animals to humans. In December 2019, the world awoke to a new zoonotic strain of CoV that was named SARS-CoV-2 (standing for severe acute respiratory syndrome coronavirus 2), which has been classified as a high-consequence infectious disease. In addition, serious complications related to COVID-19 have been reported in some patients. These include acute respiratory distress syndrome, acute renal failure, septic shock and ventilator-associated pneumonia. The pharmacist, as a healthcare practitioner, can play an important role in hindering the spread of COVID-19, and can be an active participant in national and community efforts to fight and contain this outbreak. The trend of the market of electric vehicles (EVs) in Korea is increasing because of reduction in heavy fine dust and economic benefit for purchasing EVs. With increasing number of EVs, the recycling of end-of-life battery of EVs is important to recover valuable metals such as Li and Co etc. and to control hazardous substances such as Pb, Cd and Cu. The current status on recycling policy and recycling technology of end-of-life battery of EV was explained in several countries including China, Europe, and Korea. It is necessary to immediately prepare the regulation on the storage, transportation and recycling of end-of-life battery of EV in Korea because of the safety management of end-of-life battery of EV. The new recycling scheme for the management of end-of-life batteries of EV by EPR system is proposed to secure recycling and stability because primary battery in internal combustion engine (ICE) vehicles is managed by the EPR system in Korea. For recycling of end-of-life battery of EVs, the technologies and the recycling level in Korea were compared with other countries. To develop the technical guidelines for the recycling of end-of-life battery of EV, it is proposed to set up an international committee on the recycling of end-of-life battery of EV as a new initiative in the Basel Convention. IMPORTANCE The appropriate use of adjuvant targeted therapy (TT) for high-risk locoregional renal cell carcinoma (RCC) after nephrectomy is currently unclear due to mixed results from the relevant randomized controlled trials. National-level survival outcomes and practice trends for the use of adjuvant TT in the United States have not been reported. OBJECTIVE To compare overall survival for patients who did and did not receive adjuvant TT after nephrectomy for high-risk locoregional RCC. DESIGN, SETTING, AND PARTICIPANTS This cohort study reviewed the National Cancer Database from 2006 to 2015. Selleckchem Lazertinib Patients with nonmetastatic clear cell RCC who underwent nephrectomy with either stage pT3a or greater or pN+ were included. MAIN OUTCOMES AND MEASURES Adjuvant TT was defined as receipt of TT within 3 months of nephrectomy. The primary end point was overall survival from initial diagnosis to date of death or censored at last follow-up. Baseline characteristics were described, and a multivariable analysis identified asS The propensity matched survival analysis revealed significantly decreased overall survival in patients who received off-label adjuvant TT for high-risk locoregional RCC. Since the "prostate-specific antigen (PSA) era," we have seen an increase in unnecessary biopsies, which has ultimately lead to an overtreatment of low-risk cancers. Given the limitations of prostate-specific antigen and the invasive nature of prostate biopsy several serum and urinary biomarkers have been developed. In this paper, we provide a comprehensive review of the available biomarkers for the detection clinically significant prostate cancer namely PHI, 4Kscore, PCA3, MiPS, SelectMDx, ExosomeDX. Current literature suggests that these biomarkers can improve detection of clinically significant prostate cancer reducing overtreatment and making treatment strategies more cost-effective. Nevertheless, large prospective studies with head-to-head-comparisons of the available biomarkers are necessary to fully assess the potential of incorporating biomarkers in routine clinical practice. BACKGROUND The ongoing approval of adjuvant systemic therapy in high-risk kidney tumor will increase the demand for prognostic assessment in these tumors. 9p21 deletion has been suggested as a possible prognostic feature in clear cell kidney cancer. MATERIAL AND METHODS To learn more on the prognostic relevance of 9p21 deletions in clear cell and other kidney tumors, 1,809 kidney tumor specimens were analyzed by dual-labeling fluorescence in situ hybridization (FISH) with probes for 9p21 and centromere 9 in a tissue microarray format. Results were compared to histologic tumor type, pT stage, grade, and patient outcome. RESULTS A total of 1,341 (74%) of tumor samples had interpretable FISH results. 9p21 deletion was found in 4.4% of 894 clear cell, 5.1% of 197 papillary, and 4.2% of 71 chromophobe carcinomas. 9p21 deletions were not found in 112 oncocytomas and in 21 clear cell tubulo-papillary cancers. In clear cell carcinomas, 9p deletions were associated with advanced stage (P = 0.009) and nodal metastasis (P = 0.
