There is no approved special endovascular device for use in preventing entry tears in the distal part of ascending aorta or in the aortic arch and preserving the arch branch arteries. Thus, we have designed a novel branched stent-graft, and herein report the initial clinical outcomes.

Between August 2009 and January 2014, 51 patients with aortic dissections involving the aortic arch were treated by endovascular branched stent-grafts. There were 7 Stanford type A aortic dissections, 22 retrograde type A aortic dissections, and 22 Stanford type B aortic dissections (including 4 localized aortic arch dissections). All patients were treated while in the chronic phase (>2 weeks).

All of the proximal entry tears in the arch were successfully excluded, and all of the treated branch arteries remained patent. No new cerebral infarction occurred. There was 1 death from a retrograde type A dissection, occurring 6 days after the endovascular procedure. The median follow-up period was 44 months (range, 14-66 months). No additional complications or mortality occurred. Complete thrombosis in the false lumen of the aortic arch was formed in all patients, and significant true lumen recovery and false lumen shrinkage were demonstrated in different levels of the thoracic aorta according to computed tomography angiography at 1 year postsurgery (P < .001).

In patients with aortic dissection involving the arch branches, the customized branched stent-graft may provide a feasible endovascular treatment option. A larger series of cases with longer follow-up is needed to substantiate these results.

Several mechanisms of sulfoxidation were evaluated by using methyl phenyl sulfide (PhSMe) as a model substrate in the experiments and dimethyl sulfide in the calculations. The first mechanism assumes that the active hydroperoxo species forms directly through interaction of the Ti2 (μ-OH)2 group in [γ-SiTi2 W10 O36 (OH)2 2 (μ-O)2 ](8-) (1 D) with H2 O2 . The second mechanism includes hydrolysis of Ti-O-Ti bonds linking two γ-Keggin units in structure 1 D to produce the monomer [(γ-SiW10 Ti2 O38 H2 )(OH)2 ](4-) (1 M), followed by the formation of an active hydroperoxo species upon interaction of the Ti hydroxo group with H2 O2 . Both kinetic modelling and DFT calculations support the mechanism through the monomeric species that involves the hydrolysis step. According to the DFT studies the activation of H2 O2 by compound 1 M is preferred by 6.5 kcal mol(-1) with respect to anion 1 D due to the more flexible Ti environment of the terminal Ti hydroxo group in 1 M. The calculations also indicate that for the "monomeric" mechanism two pathways are operative the mono- and the multinuclear pathway. In the mononuclear mechanism, the active group is the terminal TiOH group, whereas in the multinuclear path the active group is the bridging Ti2 (μ-OH) moiety. Moreover, unlike previous studies, the sulfoxidation is preferred through a β-oxygen atom transfer from the Ti hydroperoxo group because the α-oxygen atom transfer leads to an unfavourable seven-fold coordinated Ti environment in the transition state. Finally, we have generalised these results to other Ti-containing POMs the Ti-monosubstituted α-Keggin ion [α-PTi(OH)W11 O39 ](4-) and the dititanium-substituted sandwich-type ion [Ti2 (OH)2 As2 W19 O67 ](8-) .

Low income is known to be associated with having arthritis. However, no longitudinal studies have documented the relationship between developing arthritis and falling into poverty. The purpose of this study was to evaluate Australians who developed arthritis to determine if they had an elevated risk of falling into poverty.

Survival analysis using Cox regression models was applied to nationally representative, longitudinal survey data obtained between January 1, 2007 and December 31, 2012 from Australian adults who were ages 21 years and older in 2007.

The hazard ratio for falling into income poverty was 1.08 (95% confidence interval [95% CI] 1.06-1.09) in women who were diagnosed as having arthritis and 1.15 (95% CI 1.13-1.16) in men who were diagnosed as having arthritis, as compared to those who were never diagnosed as having arthritis. The hazard ratio for falling into multidimensional poverty was 1.15 (95% CI 1.14-1.17) in women who were diagnosed as having arthritis and 1.88 (95% CI 1.85-1.91) in men who were diagnosed as having arthritis.

Developing arthritis increases the risk of falling into income poverty and multidimensional poverty. The risk of multidimensional poverty is greater than the risk of income poverty. Given the high prevalence of arthritis, the condition is likely an overlooked driver of poverty.

To gain insight into factors involved in tumor progression and metastasis, we examined the role of noncoding RNAs in the biologic characteristics of colorectal carcinoma, in paired samples of tumor together with normal mucosa from the same colorectal carcinoma patient. The tumor and healthy tissue samples were collected and stored under stringent conditions, thereby minimizing warm ischemic time.

We focused particularly on distinctions among high-stage tumors and tumors with known metastases, performing RNA-Seq analysis that quantifies transcript abundance and identifies novel transcripts.

In comparing 35 colorectal carcinomas, including 9 metastatic tumors (metastases to lymph nodes and lymphatic vessels), with their matched healthy control mucosa, we found a distinct signature of mitochondrial transfer RNAs (MT-tRNA) and small nucleolar RNAs (snoRNA) for metastatic and high-stage colorectal carcinoma. We also found the following (i) MT-TF (phenylalanine) and snord12B expression correlated with a substantial number of miRNAs and mRNAs in 14 colorectal carcinomas examined; (ii) an miRNA signature of oxidative stress, hypoxia, and a shift to glycolytic metabolism in 14 colorectal carcinomas, regardless of grade and stage; and (iii) heterogeneous MT-tRNA/snoRNA fingerprints for 35 pairs.

These findings could potentially assist in more accurate and predictive staging of colorectal carcinoma, including identification of those colorectal carcinomas likely to metastasize.

Tumor-infiltrating lymphocytes (TIL) are associated with a better prognosis in high-grade serous ovarian cancer (HGSC). However, it is largely unknown how this prognostic benefit of TIL relates to current standard treatment of surgical resection and (neo-)adjuvant chemotherapy. To address this outstanding issue, we compared TIL infiltration in a unique cohort of patients with advanced-stage HGSC primarily treated with either surgery or neoadjuvant chemotherapy.

Tissue microarray slides containing samples of 171 patients were analyzed for CD8(+) TIL by IHC. Freshly isolated CD8(+) TIL subsets were characterized by flow cytometry based on differentiation, activation, and exhaustion markers. Relevant T-cell subsets (CD27(+)) were validated using IHC and immunofluorescence.

A prognostic benefit for patients with high intratumoral CD8(+) TIL was observed if primary surgery had resulted in a complete cytoreduction (no residual tissue). By contrast, optimal (<1 cm of residual tumor) or incomplete cytoreduction fully abrogated the prognostic effect of CD8(+) TIL. Subsequent analysis of primary TIL by flow cytometry and immunofluorescence identified CD27 as a key marker for a less-differentiated, yet antigen-experienced and potentially tumor-reactive CD8(+) TIL subset. In line with this, CD27(+) TIL were associated with an improved prognosis even in incompletely cytoreduced patients. Neither CD8(+) nor CD27(+) cell infiltration was of prognostic benefit in patients treated with neoadjuvant chemotherapy.

Our findings indicate that treatment regimen, surgical result, and the differentiation of TIL should all be taken into account when studying immune factors in HGSC or, by extension, selecting patients for immunotherapy trials.

Still, cross-cultural evidence for its construct validity in heterogeneous community samples remains relatively scarce. Moreover, little is known about the interchangeability of both instruments. The present study addresses these research gaps by comparing the SRP-III and SRP-SF factorial construct validity and nomological network in a Belgian community sample. The four-factor model of psychopathy was evaluated ( N = 1,510) and the SRP scales' relationship with various external correlates (i.e., attachment, bullying and victimization, right-wing attitudes, right-wing authoritarianism, and response styles) was examined ( n = 210). Both SRP versions demonstrated a good fit for the four-factor model and a considerable overlap with the nomological network of psychopathy. The results suggested that the SRP-SF provides a viable alternative to the SRP-III for assessment in the community. Theoretical and practical implications are discussed.Psychological assessments are highly dependent on the forthrightness and sincere efforts of examinees. In particular, evaluations in forensic settings must consider whether feigning or other response styles are utilized to intentionally distort the clinical presentation. The current study examines the effectiveness of the Inventory of Legal Knowledge (ILK) at detecting feigned incompetency within a sample of jail detainees. As an ancillary goal, several scales of the Standardized Assessment of Miranda Abilities were included in the same within-subjects simulation design. Results of the total ILK score raised concerns regarding the mischaracterization of genuine offenders as "suggestive of feigning." Pending cross-validation, however, a Revised ILK proved highly effective, using a floor effect detection strategy. Although intended for Miranda-specific abilities, several detection strategies on the Standardized Assessment of Miranda Abilities appeared to be very promising within a broadened context of feigned incompetency.
