MET overexpression as a hallmark of the epithelial-mesenchymal transition (EMT) phenotype in colorectal cancer.
Authors: Kanwal Pratap Singh Raghav, Wenting Wang, Michael J. Overman, Scott Kopetz
Journal: Journal of Clinical Oncology (2013)

334 Background: Dysregulation of the proto-oncogene MET (mesenchymal-epithelial transition factor gene) has been implicated in tumorigenesis and correlates with worse survival and chemo/radio-resistance in colorectal cancer (CRC). EMT has been identified as a dominant molecular characteristic of a subset of CRC tumors and represents a key feature in the developing colorectal taxonomy. The purpose of this study was to compare protein expression of MET with protein/gene expression of EMT markers and other clinicopathological characteristics, and to evaluate its impact on overall survival (OS). Methods: We performed an exploratory analysis of 590 CRC samples using data from The Cancer Genome Atlas. Fisher-exact test and Pearson’s method was used to determine the relationship between MET protein expression, clinicopathological characteristics and EMT marker protein expression by reverse-phase protein array (RPPA) and EMT-associated gene expression by RNA-sequencing. Regression tree method was applied to find the best cutoff point for MET using patients with available survival data. Overall survival (OS) was estimated non-parametrically using Kaplan-Meier curve and log-rank test was used to evaluate hazard ratio. Results: MET expression by RPPA did not correlate with traditional clinicopathologic characteristics. MET was overexpressed in 17% of CRC tumors and was significantly associated with OS (HR 2.92; 95% CI: 1.45 - 5.92). Correlation analysis of MET levels with gene expression of EMT markers AXL, CDH1, FGFR1, SNAIL, TWIST1/2, VIM, SLUG, ZEB1/2, FN1 demonstrated that the highest quartile of MET protein expression was associated with a 1.5 fold increase in ZEB1 (p = 0.002), a 1.4 fold increase in AXL (p = 0.005) and ZEB2 (p = 0.008), and a 1.3 fold increase in VIM (p = 0.02). MET expression also correlated strongly with protein expressions of SNAIL (transcription factor for EMT) (r = 0.96) and ERCC1 (r = 0.83) (a marker for oxaliplatin chemo-resistance). Conclusions: Increased MET protein expression is seen in 17% of CRC tumors and strongly correlates with a molecular EMT phenotype and poor survival in patients with CRC. MET protein expression may be a surrogate biomarker for this unique subset of CRC.

D2 dopamine receptor gene is associated but not linked with alcoholism
Authors: C. R. Cloninger
Journal: JAMA (1991)

There has been intense interest in replicating the 1990 report in<i>JAMA</i>that the minor allele of<i>DRD2</i>(the D<sub>2</sub>dopamine receptor gene on human chromosome 11 at q22-q23) may increase susceptibility to severe alcoholism in some cases. In May 1990 Blum et al<sup>1</sup>reported that 24 (69%) of 35 alcoholics carried the Al allele of<i>DRD2</i>compared with only seven (20%) of 35 nonalcoholics. Their analysis was based on brain tissue of deceased subjects, and the alcoholics were described as having experienced repeated treatment failures in their alcoholism rehabilitation, with their deaths attributable primarily to the chronic damaging effects of alcohol. It was surprising that a single gene could be so strongly associated with a common disorder that is known to be developmentally complex and genetically heterogeneous.<sup>2</sup>Accordingly, there was caution and skepticism about the report because of its small sample size and the surprising strength
Cognitive Dysfunction in Homeless Adults: A Systematic Review
Authors: Sean Spence, Richard Stevens, Randolph Parks
Journal: Journal of the Royal Society of Medicine (2004)

Homelessness is associated with multiple adversities that might impact upon brain function. We performed a review of published work to assess evidence of cognitive dysfunction among adults who are homeless. Despite liberal inclusion criteria only seventeen publications were identified, these describing eighteen samples mainly from the USA. Although the total number of individuals studied is small (about 3300) and the samples are heterogeneous, most studies indicate a considerable burden of cognitive dysfunction among homeless people. Such dysfunction might be expected to impact upon their ability to reintegrate into society, thereby undermining policies of inclusiveness. In clinical practice, assessment of homeless adults should include their cognitive state.

Granulomatous hepatitis associated with jejunoileal bypass surgery
Authors: E. D. Kalat
Journal: JAMA (1981)

GRANULOMATOUS hepatitis is an uncommon form of liver pathology. It has been described as occurring after jejunoileal bypass surgery. Some of these patients had tuberculosis. In other bypass patients with hepatic granulomas, neither a diagnosis of tuberculosis nor of sarcoidosis was proved, and the cause of the granulomas was obscure.<sup>1,2</sup> We report the case of an intestinal bypass patient in whom granulomata developed and who then underwent reanastomosis of her intestinal tract with resolution of the granulomas without antituberculous therapy. <h3>Report of a Case</h3> A 28-year-old woman weighing 127.2 kg underwent jejunoileal bypass surgery. She was hospitalized six months later with nausea, vomiting, weakness, dizziness, and depression. Liver enzyme level abnormalities were present, and a liver biopsy specimen showed extensive fatty metamorphosis. Eighteen months later she weighed 55.4 kg and complained of undesired weight loss, night sweats, shaking chills, easy fatigue, and diarrhea. Physical examination uncovered hepatosplenomegaly but no

Manchester and Salford Provident Dispensaries
Authors: T. N. Orchard
Journal: BMJ (1886)

<h3>Objectives</h3> This study was performed to analyse anaesthesia-related complications and side effects in patients undergoing transcatheter aortic valve implantation (TAVI) under general anaesthesia. <h3>Design</h3> Retrospective study. <h3>Setting</h3> The study was performed as a single-centre study in a hospital of tertiary care in Germany. <h3>Participants</h3> All 853 patients, who underwent TAVI at the Universitätsklinikum Regensburg between January 2009 and July 2015, were included. 52.5% were female patients. <h3>Primary and secondary outcome measures</h3> We gathered information, such as recent illness, vital parameters and medication administered during the intervention and postoperatively for 12 hours. We analysed all anaesthesia-related complications and anaesthesia-related side effects that occurred during the intervention and entire hospital stay. <h3>Results</h3> We analysed all 853 TAVI procedures. The mean patient age was 79 ± 6 years. In 99.5% of cases, we used volatile-based anaesthesia. 2.8% (n=24; transfemoral (TF): n=19 [3.8%]; transapical (TA): n=5 [1.4%]) of all cases suffered from anaesthesia-related complications. 819 (TF: n=447; TA: n=372) anaesthesia-related side effects occurred in 586 (68.7%, TF: n=325 [64.2%], TA: n=261 [75.2%]) patients. Neither the complications nor the side effects had any serious consequences. Intraoperative hypothermia in 44% of cases (TF: n=202 [39.9%]; TA: n=173 [49.9%]) and postoperative nausea and vomiting in 27% (n=232; TF: n=131 [25.9%], TA: n=101 [29.1%]) of cases were the most common anaesthesia-related side effects. <h3>Conclusion</h3> In this study, serious anaesthesia-related complications were rarely seen, and non-critical anaesthesia-related side effects could have been avoided through consistent prophylaxis and management. Therefore, despite their high anaesthetic risk, general anaesthesia is justifiable in patients who underwent TAVI.

Nonanoxic aerosol arrhythmias
Authors: N. C. Flowers
Journal: JAMA (1972)

Cardiac arrhythmias were produced in dogs which were allowed to breathe aerosols propelled with fluorinated hydrocarbons. In spite of mixing with room air in ten animals, and careful maintenance of normal arterial oxygen tension, carbon dioxide tension, pH, base excess, and serum carbon dioxide level in six animals, the same general pattern of rhythm disturbances prevailed. These consisted mainly of slowing of the rate of the sinoatrial pacemaker with resultant junctional or ventricular escape rhythm and ultimate electrical asystole or ventricular fibrillation in eight animals, in spite of the fact that exposure to the agents was stopped at the earliest sign of rhythm change.
Contribution of complement-stimulated hepatic macrophages and neutrophils to endotoxin-induced liver injury in rats
Authors: H Jaeschke
Journal: Hepatology (1994)

The role of complement as potential activator for tissue macrophages and neutrophils was investigated in an experimental model of endotoxin-induced liver injury in male Fischer rats. Injection of Salmonella enteritidis endotoxin (1 mg/kg) into Corynebacterium parvum-pretreated animals (7 mg/kg; single dose 6 days before endotoxin) resulted in severe oxidant stress, as indicated by a 37-fold increase of plasma levels of glutathione disulfide (basal concentration, 0.36 ± 14 μmol/L), accumulation of neutrophils in the liver (600 ± 31 neutrophils/50 high-power fields) and liver injury (plasma ALT, 1184 ± 185 U/l; necrosis; 19% ± 3%) 10 hr after endotoxin. The oxidant stress induced by 1 mg/kg endotoxin in the C. parvum-treated animals was always significantly higher than that in control animals receiving the same dose of endotoxin. Inhibition of complement activation with the soluble complement receptor type 1 attenuated the oxidant stress and liver injury by 50% to 65% but had no effect on hepatic neutrophil accumulation or plasma tumor necrosis factor-α levels. Treatment with a monoclonal antibody directed against the α-chain of CD11b/CD18 adhesion proteins (clone 17), which was highly effective in attenuating ischemia-reperfusion injury in the liver by reducing the number of neutrophils and functionally inactivating these cells, neither protected against parenchymal cell injury nor affected hepatic neutrophil infiltration in the C. parvum model. We conclude that reactive oxygen derived from complement-stimulated macrophages is critical for the development of liver injury in the C. parvum/endotoxin model. (HEPATOLOGY 1994; 19:973–979.)
