Psychological distress is prevalent in this group of ED physicians, and it deserves attention from the whole society. Burnout and job satisfaction among ED physicians are at a 'moderate' level. Burnout is negatively associated with higher job satisfaction.

BackgroundMolecular epidemiological studies have shown that gene polymorphisms of vitamin D receptor (VDR) are associated with prostate cancer risks. However, previous results from many molecular studies remain inconsistent.MethodsBlood samples were collected from 122 prostate cancer patients and 130 age-matched control subjects in the Han population of Southern China. The differences of VDR gene polymorphism between cancer cases and controls were determined by PCR-RFLP, examiming FokI (exon 2), BsmI, Tru9I, ApaI (intron 9), and TaqI (exon 9). Associations between the VDR gene polymorphism and prostate cancer risk were calculated in an unconditional logistic regression model. Linkage disequilibrium and haplotypes were analyzed with the SHEsis software.ResultsOf five polymorphisms, BsmI was shown to associate with prostate cancer, while FokI, Tru9I, ApaI, and TaqI did not show any significant association. After adjustment for age, the BsmI 'B' allele was associated with an almost 1/3-fold risk (OR = 0.35, 95%CI: 0.15-0.80) of the occurrence of prostate cancer, a 1/5-fold risk (OR = 0.20, 95%CI: 0.06-0.68) of poorly differentiated prostate cancer, and a 1/10-fold risk (OR = 0.10, 95%CI: 0.01-0.78) of aggressive prostate cancer compared with the 'b' allele, especially among older men (>71 years). In addition, haplotype analysis revealed that the 'F-b-U-A-T' was more frequent found in cases than in controls (3.4% vs 0.0%, P = 0.0035), while the frequency of haplotype 'F-B-U-a-T' was 0.8% in cases, significantly lower than in controls (3.9%, P = 0.019).ConclusionOur experiments provide evidences that genetic polymorphisms in the VDR gene may be potential risk factors for prostate cancer in the Han population of southern China and the susceptibility to prostate cancer is associated with ethnicity and geographic location.

Bladder cancer (BC) is one of the most common cancers worldwide with a high progression rate and poor prognosis. The Hippo signalling pathway is a conserved pathway that plays a crucial role in cellular proliferation, differentiation and apoptosis. Furthermore, dysregulation and/or malfunction of the Hippo pathway is common in various human tumours, including BC. In this review, an overview of the Hippo pathway in BC and other cancers is presented. We focus on recent data regarding the Hippo pathway, its network and the regulation of the downstream co‐effectors YAP1/TAZ. The core components of the Hippo pathway, which induce BC stemness acquisition, metastasis and chemoresistance, will be emphasized. Additional research on the Hippo pathway will advance our understanding of the mechanism of BC as well as the development and progression of other cancers and may be exploited therapeutically.
