Systematic review of preoperative, intraoperative and postoperative risk factors for colorectal anastomotic leaks
Authors: McDermott F D , Heeney A , Kelly M E , Steele R J , Carlson G L , Winter D C
Published: February 2015

Background

Anastomotic leak (AL) represents a dreaded complication following colorectal surgery, with a prevalence of 1–19 per cent. There remains a lack of consensus regarding factors that may predispose to AL and the relative risks associated with them. The objective was to perform a systematic review of the literature, focusing on the role of preoperative, intraoperative and postoperative factors in the development of colorectal ALs.

Methods

A systematic review was performed to identify adjustable and non-adjustable preoperative, intraoperative and postoperative factors in the pathogenesis of AL. Additionally, a severity grading system was proposed to guide treatment.

Results

Of 1707 papers screened, 451 fulfilled the criteria for inclusion in the review. Significant preoperative risk factors were: male sex, American Society of Anesthesiologists fitness grade above II, renal disease, co-morbidity and history of radiotherapy. Tumour-related factors were: distal site, size larger than 3 cm, advanced stage, emergency surgery and metastatic disease. Adjustable risk factors were: smoking, obesity, poor nutrition, alcohol excess, immunosuppressants and bevacizumab. Intraoperative risk factors were: blood loss/transfusion and duration of surgery more than 4 h. Stomas lessen the consequences but not the prevalence of AL. In the postoperative period, CT is the most commonly used imaging tool, with or without rectal contrast, and a C-reactive protein level exceeding 150 mg/l on day 3–5 is the most sensitive biochemical marker. A five-level classification system for AL severity and appropriate management is presented.

Conclusion

Specific risk factors and their potential correction or indications for stoma were identified. An AL severity score is proposed to aid clinical decision-making.
The Use of Risk and Need Factors in Forensic Mental Health Decision‐Making and the Role of Gender and Index Offense Severity

Published: February 2015

Canadian legislation makes Review Boards (RBs) responsible for rendering dispositions for individuals found Not Criminally Responsible on account of Mental Disorder (NCRMD) after considering public safety, the mental condition of the accused, and his/her potential for community reintegration. We reviewed 6,743 RB hearings for 1,794 individuals found NCRMD in the three largest Canadian provinces to investigate whether items from two empirically supported risk assessment measures, the Historical Clinical Risk Management‐20 and the Violence Risk Appraisal Guide, were considered. Less than half the items were included in expert reports or in RBs' reasons for dispositions, and consideration of these items differed according to gender and index offense severity of the accused. These items included evidence‐based risk factors and/or legally specified criteria: mental health, treatment, and criminal history. These results illustrate the gap between research on risk factors and the integration of this evidence into practice. In particular, we recommend the implementation of structured measures to reduce the potential for clinicians to be unduly influenced by gender and offense severity.

Pancreatic cancer and FOLFIRINOX: a new era and new questions
Authors: Marsh Robert De W. , Talamonti Mark S. , Katz Matthew Harold , Herman Joseph M.
Published: February 2015

FOLFIRINOX (FFX) was introduced to clinical practice in 2010 following publication of the PRODIGE 4/ACCORD 11 study, which compared this novel regimen to gemcitabine in metastatic pancreatic cancer. Median overall survival, progression‐free survival, and objective responses were all superior with FFX and there was improved time to definitive deterioration in quality of life. Despite initial concerns over toxicity, there has been rapid uptake of this regimen, both revolutionizing management and opening the door to innovative research. As experience with FFX has accrued, many questions have arisen including the management of toxicities, the impact of frequent modifications, the optimal number of cycles, integration with other regimens and modalities, interpretation of radiologic and serologic response, utility of molecular signatures, and potential benefit in unique clinical settings such as pre‐ and postsurgery. This review will closely examine these issues, not only to summarize current knowledge but also to fuel scientific debate.

Searchable ciphertext‐policy attribute‐based encryption with revocation in cloud storage
Authors: Li Jiguo , Shi Yuerong , Zhang Yichen
Published: February 2015

To protect the sensitive data outsourced to cloud server, outsourcing data in an encrypted way has become popular nowadays. However, it is not easy to find the corresponding ciphertext efficiently, especially the large ciphertext stored on cloud server. Besides, some data owners do not want those users who attempt to decrypt to know the sensitive access structure of the ciphertext because of some business or private reasons. In addition, the user attributes revocation and key updating are important issues, which affect application of ciphertext‐policy attribute‐based encryption (CP‐ABE) in cloud storage systems. To overcome the previous problems in cloud storage, we present a searchable CP‐ABE with attribute revocation, where access structures are partially hidden so that receivers cannot extract sensitive information from the ciphertext. The security of our scheme can be reduced to the decisional bilinear Diffie–Hellman (DBDH) assumption and decisional linear (DL) assumption. Copyright © 2015 John Wiley & Sons, Ltd.
The reliability of thyroid nodule ultrasound features and size to predict malignancy in fine needle aspiration specimens: Practical utility for the evaluating pathologist
Authors: Samulski T. Danielle , Shutty Christopher , LiVolsi Virginia A. , Montone Kathleen , Baloch Zubair
Published: February 2015

Background

The prognostic impact of ultrasound features of thyroid nodules is debated. We explore the correlation between nodule size, echogenicity on US, and malignancy.

Methods

We performed a retrospective review of thyroid nodules undergoing ultrasound guided FNA (US‐FNA) at our institution between 01/2008‐05/2013.

Results

In all, 2,403 nodules from 2,293 patients (age range 14–91, mean 54, median 56, M: F‐1:3.2) underwent US‐FNA. 766 nodules were resected, 337 were malignant (size range 0.4‐8.7 cm, median 2 cm, mean 2.37 cm,) and 429 were benign (size range 0.5–9.7 cm, median 2.5 cm, mean 2.79 cm). The malignant diagnoses included: classical variant of PTC 77 (size range 0.5–5.5 cm, mean 1.5 cm), follicular variant of PTC 209 (size range 0.14–7.5 cm, mean 2.1 cm), tall cell variant of PTC 7 (size range 0.5–2.4 cm, mean1.4 cm), poorly differentiated carcinoma 5 (size range 5–8.7 cm, mean 6.42 cm), follicular carcinoma 27 (size range 0.5–7 cm, mean 3.03 cm), and oncocytic follicular carcinoma 9 cases (size range 1.4–7.2 cm, mean 3.2 cm). Of the malignant nodules with echogenicity reported on US, 93 were hypoechoic, 26 hyperechoic, 20 isoechoic, and 76 heteroechoic; increased vascularity on US was seen in 69/337 (20%). On US, 105 benign nodules were reported as hypoechoic, 35 hyperechoic, 43 isoechoic, and 100 as heterogeneous; increased vascularity on US was seen in 88/429 (20%).

Conclusions

A malignant diagnosis was more common in thyroid nodules ≤1.0 cm. No differences were noted in the US‐features of benign and malignant thyroid nodules. Diagn. Cytopathol. 2015;43:471–477. © 2015 Wiley Periodicals, Inc.
Divergence of craniofacial developmental trajectories among avian embryos
Authors: Smith Francis J. , Percival Christopher J. , Young Nathan M. , Hu Diane , Schneider Richard A. , Marcucio Ralph S. , Hallgrimsson Benedikt
Published: February 2015

Background:Morphological divergence among related species involves changes to developmental processes. When such variation arises in development has garnered considerable theoretical interest relating to the broader issue of how development may constrain evolutionary change. The hourglass model holds that while early developmental events may be highly evolvable, there is a phylotypic stage when key developmental events are conserved. Thus, evolutionary divergence among related species should tend to arise after such a stage of reduced evolvability and, consequently, reduced variation among species. We test this prediction by comparing developmental trajectories among three avian species of varying relatedness (chick, quail, and duck) to locate their putative point of divergence. Three‐dimensional geometric morphometrics and trajectory analyses were used to measure the significance of the facial shape variation observed among these species.Results:Duck embryos, being more distantly related, differed from the more closely‐related chick and quail embryos in the enlargement of their frontonasal prominences. Phenotypic trajectory analyses demonstrated divergence of the three species, most notably, duck.Conclusions:The results demonstrate that the two more closely related species share similar facial morphologies for a longer time during development, while ducks diverge. This suggests a surprising lability of craniofacial development during early face formation.Developmental Dynamics 244:1158–1167, 2015. © 2015 Wiley Periodicals, Inc.
Critical role of YY1 in cardiac morphogenesis
Authors: Beketaev Ilimbek , Zhang Yi , Kim Eun Young , Yu Wei , Qian Ling , Wang Jun
Published: February 2015

Background: Yin Yang 1 (YY1), the only DNA binding polycomb group protein, was reported to regulate cardiomyocyte differentiation during early cardiac mesoderm development. However, whether it contributes to cardiac morphogenesis at later developmental stage(s) during embryogenesis is unknown.

Results: We excised YY1 in murine hearts during embryogenesis using two temporal‐spatially controlled cre activation approaches, and revealed critical roles of YY1 in cardiac structural formation. Alpha‐myosin heavy chain‐cre (α‐MHC‐cre)‐mediated cardiomyocyte‐specific ablation of YY1 (MHC‐YY1) resulted in perinatal death of mutant mice, and Nkx2.5‐cre‐mediated YY1 null embryos (Nkx2.5‐YY1) died embryonically. In the Nkx2.5‐YY1 mutants, the endocardial cushions (ECs) of both atrioventricular canal (AVC) and outflow tract (OFT) were hypoplastic due to decreased proliferation and increased apoptosis. Endothelial‐to‐mesenchymal transition (EMT) progress was also compromised in ECs. Nkx2.5‐YY1 mutant hearts had normal formation of extracellular matrix, suggesting that the impaired EMT resulted from the direct loss of YY1. We further uncovered that a number of factors that are involved in normal cardiogenesis were downstream targets of YY1.

Conclusions: YY1 plays a critical role in cardiac development and occupies a high‐level position within the hierarchy of the cardiac transcriptional network that governs normal cardiogenesis. Developmental Dynamics 244:669–680, 2015. © 2015 Wiley Periodicals, Inc.
Stress relief may promote the evolution of greater phenotypic plasticity in exotic invasive species: a hypothesis
Authors: Huang Qiao Q. , Pan Xiao Y. , Fan Zhi W. , Peng Shao L.
Published: February 2015

Invasion ecologists have often found that exotic invaders evolve to be more plastic than conspecific populations from their native range. However, an open question is why some exotic invaders can even evolve to be more plastic given that there may be costs to being plastic. Investigation into the benefits and costs of plasticity suggests that stress may constrain the expression of plasticity (thereby reducing the benefits of plasticity) and exacerbate the costs of plasticity (although this possibility might not be generally applicable). Therefore, evolution of adaptive plasticity is more likely to be constrained in stressful environments. Upon introduction to a new range, exotic species may experience more favorable growth conditions (e.g., because of release from natural enemies). Therefore, we hypothesize that any factors mitigating stress in the introduced range may promote exotic invaders to evolve increased adaptive plasticity by reducing the costs and increasing the benefits of plasticity. Empirical evidence is largely consistent with this hypothesis. This hypothesis contributes to our understanding of why invasive species are often found to be more competitive in a subset of environments. Tests of this hypothesis may not only help us understand what caused increased plasticity in some exotic invaders, but could also tell us if costs (unless very small) are more likely to inhibit the evolution of adaptive plasticity in stressful environments in general.
Low‐Power Supply Circuit Using Off‐Chip Resonant Circuit for Adiabatic Logic
Authors: TAKAHASHI YASUHIRO , SATO HISAO
Published: February 2015

This paper presents a low‐power sinusoidal supply circuit for our proposed adiabatic logic (2PC2AL). The proposed supply circuit consists of three parts: LC resonant circuit, voltage generator circuit, and peak control circuit. The proposed circuit is simulated using 0.18 μm CMOS technology. The simulation results show that the power dissipation of the proposed voltage generator is 10.8 μW at a 100 nA load, and that of the proposed sinusoidal supply circuit is 35.5 μW at 100 kHz. The power dissipation values of the adiabatic/nonadiabatic 16‐bit MPU decoders are also compared. At transition frequencies of 10 kHz to 1 MHz, the proposed decoder with a sinusoidal supply circuit shows a maximum reduction of 75% in power dissipation from to that of a static CMOS.
