Emerging evidence suggests that iron-mediated lipid oxidation also facilitates immune eradication of cancer. However, the regulatory mechanisms of iron metabolism in cancer remain unclear. Here we identify OTUD1 as the deubiquitinase of iron-responsive element-binding protein 2 (IREB2), selectively reduced in colorectal cancer. Clinically, downregulation of OTUD1 is highly correlated with poor outcome of cancer. Mechanistically, OTUD1 promotes transferrin receptor protein 1 (TFRC)-mediated iron transportation through deubiquitinating and stabilizing IREB2, leading to increased ROS generation and ferroptosis. Moreover, the presence of OTUD1 promotes the release of damage-associated molecular patterns (DAMPs), which in turn recruits the leukocytes and strengthens host immune response. Reciprocally, depletion of OTUD1 limits tumor-reactive T-cell accumulation and exacerbates colon cancer progression. Our data demonstrate that OTUD1 plays a stimulatory role in iron transportation and highlight the importance of OTUD1-IREB2-TFRC signaling axis in host antitumor immunity.

Less empirical attention has been paid to the positive relationship between voice behaviour and voice speaker development, such as self-leadership. The present study explores the relationship among nurses' voice, perceived insider status and self-leadership.

This study was based on time-lagged survey data collected from 608 frontline nurses. jamovi and PROCESS macro were used for analysis.

Promotive voice and prohibitive voice were positively associated with self-leadership. Perceived inside status mediated the relationship between promotive voice/prohibitive voice and self-leadership. Prohibitive voice was more strongly related to self-leadership than promotive voice.

When nurses dare to voice, nurses' self-leadership can be enhanced through perceived insider status improving, especially for nurses who dare to prohibitive voice.

Nurse managers should protect the privacy of voice, continually provide feedback on voice and set up special encouragement for prohibitive voice.

Laparoscopic cholecystectomy is a common surgery with a varying difficulty level. Difficult laparoscopic cholecystectomy may be experienced by many surgeons. If difficult procedures are predicted preoperatively, surgeons may be able to plan the surgical approach and treatment accordingly. Studies have reported using blood and clinical imaging data to predict difficult cholecystectomy. However, to our knowledge, no studies have reported using MRI. The purpose of this study was to evaluate the usefulness of MRI as a predictor of difficult laparoscopic cholecystectomy.

We retrospectively evaluated 25 patients with cholecystitis or biliary colic who had undergone diffusion-weighted whole-body imaging before laparoscopic cholecystectomy. The apparent diffusion coefficient value of the cystic duct was measured and its relationship with operative time and blood loss was examined to assess the capacity of diffuse-weighted whole-body imaging to predict difficult cholecystectomy. Further, we collected blood data an over time to determine optimal surgical timing.

The present study was designed in order to elucidate the roles of serum interleukin 6 (IL-6) in the pathogenesis in neuropsychiatric systemic lupus erythematosus (NPSLE).

Paired serum and cerebrospinal fluid (CSF) samples were obtained from 101 patients with SLE when they presented active neuropsychiatric manifestations (69 patients with diffuse psychiatric/neuropsychological syndromes [diffuse NPSLE] and 32 patients with neurologic syndromes or peripheral nervous system involvement [focal NPSLE]) and from 22 control patients without SLE with noninflammatory neurological diseases. The levels of albumin and IL-6 in CSF and sera were measured by enzyme-linked immunosorbent assay.

Serum IL-6 and CSF IL-6 were elevated in NPSLE compared with non-SLE controls. Among NPSLE, serum IL-6 and CSF IL-6 were significantly elevated in acute confusional state (ACS) compared with non-ACS diffuse NPSLE (anxiety disorder, cognitive dysfunction, mood disorder, and psychosis) or focal NPSLE. Q albumin (CSF/serum albumin quotient) was also significantly higher in ACS than in the other two groups of NPSLE. Of note, serum IL-6 (r = 0.2801, p = 0.0207), but not CSF IL-6 (r = 0.1602, p = 0.1918), was significantly correlated with Q albumin in patients with diffuse NPSLE, including ACS and non-ACS.

These results indicate that serum IL-6 as well as CSF IL-6 is involved in the pathogenesis of NPSLE. Moreover, it is suggested that serum IL-6 might play a most important role in blood-brain barrier breakdown in NPSLE.

Unique market-wide administrative data allow to exploit a natural experiment in Germany in which the relative attractiveness of greatly divergent reimbursements for clinically similar patients changes in the market for sepsis conditions on January 1, 2010. This natural experiment provides-unintentionally-extra reimbursements in cases in which hospitals reorganize transfers for deceasing patients to other facilities, alter the time of death, the choice of the condition being chiefly responsible for the hospital admission (primary diagnosis), or the intensity of mechanical ventilation. SP600125 The differences-in-differences results demonstrate that hospitals primarily alter the primary diagnosis. As the choice of the primary diagnosis is the backbone of the design of modern DRG systems, the findings suggest that payment contracts between hospitals and payers based on modern DRG algorithms may not necessarily improve patient welfare.
