Abstract

Background
Recent neoadjuvant strategies for high-risk colonic tumours have renewed interest in accurate preoperative staging. The aim of this study was to validate prospectively the accuracy of multidetector computed tomography (MDCT) in stratifying patients into good and poor prognostic groups in a multicentre setting.

Methods
Staging MDCT scans of 84 patients with colonic cancer were reviewed by two independent radiologists and stratified into low-risk (T1/T2 and T3 with extramural tumour depth (EMD) of less than 5 mm) and high-risk (T3 with EMD of at least 5 mm and T4) tumours. Nodal status and extramural venous invasion (EMVI) were also assessed.

Results
The accuracy, sensitivity, specificity and positive predictive value of stratification by CT compared with histological examination was 74 (95 per cent confidence interval 64 to 82), 78 (65 to 87), 67 (49 to 81) and 81 (68 to 89) per cent respectively. Accuracy for detecting malignant lymph nodes and EMVI was 58 and 70 per cent respectively. The agreement for predicting prognostic stratification was moderate (κ = 0·54).

Conclusion
As the ability of CT to identify node status is poor, the depth of tumour invasion beyond the muscularis propria is the most accurate way to identify patients with a poor prognosis who may be suitable for neoadjuvant treatment.

Published: June 2010

AbstractBackgroundThe aim of the study was to evaluate the results of laparoscopic adjustable gastric banding (LAGB) in patients lost to follow-up.MethodsPatients lost to follow-up were identified from a consecutive cohort of 495 patients who underwent LAGB between November 1995 and September 2006. These patients were asked to return to follow-up and their actual weight was assessed.ResultsOf 93 patients lost to follow-up, 73 were motivated to reattend. Of these, 60 per cent (44 patients) had lost less than 25 per cent of excess weight, compared with 16·3 per cent (P &lt; 0·001), 27·0 per cent (P &lt; 0·001) and 42 per cent (P = 0·026) of patients after 2, 4 and 8 years of regular follow-up.ConclusionPatients lost to follow-up are more likely to have poor weight loss, emphasizing the importance of follow-up after LAGB. Outcome after surgery for morbid obesity should include patients lost to follow-up as a measure of overall success.

Abstract

Background
The aim of this study was to assess possible differences in mortality between men and women with an abdominal aortic aneurysm (AAA) treated either by elective repair or following aneurysm rupture.

Methods
A systematic literature search was performed using the MEDLINE, Cochrane and Embase databases. Data were analysed by means of bivariate random-effects meta-analysis. Data were pooled and odds ratios (ORs) calculated for women compared with men.

Results
Sixty-one studies (516 118 patients) met the predetermined inclusion criteria. Twenty-six reported on elective open AAA repair, 21 on elective endovascular repair, 25 on open repair for ruptured AAA and one study on endovascular repair for ruptured AAA. Mortality rates for women compared with men were 7·6 versus 5·1 per cent (OR 1·28, 95 per cent confidence interval (c.i.) 1·09 to 1·49) for elective open repair, 2·9 versus 1·5 per cent (OR 2·41, 95 per cent c.i. 1·14 to 5·15) for elective endovascular repair, and 61·8 versus 42·2 per cent (OR 1·16, 95 per cent c.i. 0·97 to 1·37) in the group that had open repair for rupture. The group that had endovascular repair for ruptured AAA was too small for meaningful analysis.

Conclusion
Women with an AAA had a higher mortality rate following elective open and endovascular repair.
Hypoxia stimulates osteoclast formation from human peripheral blood
Authors: Utting Jennifer C. , Flanagan Adrienne M. , Brandao‐Burch Andrea , Orriss Isabel R. , Arnett Timothy R. 
Published: June 2010

AbstractActive pathological bone destruction in humans often occurs in locations where oxygen tension (pO2) is likely to be low, for example, at the sites of tumours, inflammation, infections and fractures, or the poorly vascularized yellow fatty marrow of the elderly. We examined the effect of pO2 on formation of osteoclasts, the cells responsible for bone resorption, in 14‐day cultures of normal human peripheral blood mononuclear cells (hPBMCs) on ivory discs. Hypoxia (1–2% O2) caused threefold increases in the number of osteoclasts formed, compared with 20% O2. Hypoxia also caused a twofold increase in the number of nuclei per osteoclast, leading to stimulations of resorption pit formation of up to 10‐fold. Exposure to hypoxia led to stabilization of the hypoxia‐inducible factors, HIF1α and HIF2α, and upregulation of vascular endothelial growth factor and interleukin‐6 expression by hPBMCs. These findings help explain why extravasation of mononuclear precursors into relatively O2‐deficient bone microenvironments could result in osteoclast formation and suggest a new mechanism for the bone loss associated with the pathophysiological conditions where hypoxia commonly occurs.

Nitroguanidine‐Fused Bicyclic Guanidinium Salts: A Family of High‐Density Energetic Materials
Authors: Wang Ruihu , Guo Yong , Sa Rongjian , Shreeve Jean'ne M. 
Published: June 2010

AbstractA series of nitroguanidine‐fused bicyclic guanidinium energetic salts paired with inorganic energetic anions, mono‐ and di‐tetrazolate anions were synthesized through simple metathesis reactions of 2‐iminium‐5‐nitriminooctahydroimidazo[4,5‐d]imidazole chloride and sulfate with the corresponding silver and barium salts, respectively, in aqueous solution. Key physical properties, such as melting point, thermal stability, and density were measured. The relationship between the structures of the salts and these properties was determined. The salts exhibit thermal stability and density (>1.60 g cm−3) that are comparable to currently used explosives The structures of the nitrate salt 1 and the dinitrocyanomethanide salt 4 were confirmed by single‐crystal X‐ray analysis. Densities, heats of formation, detonation pressures and velocities, and specific impulses were calculated. All of the salts possess positive calculated heats of formation and most of them exhibit promising energetic performance that is comparable with those of 1,3,5‐trinitrobenzene (TNT), 1,3,5‐triamino‐2,4,6‐trinitrobenzene (TATB), and cyclotrimethylenetrinitramine (RDX). The effect of the fused bicycle 2‐iminium‐5‐nitriminooctahydroimidazo[4,5‐d]imidazole on these physicochemical properties was examined and discussed.

Published: June 2010

AbstractA short overview on the structural design of the Hoveyda–Grubbs‐type ruthenium initiators chelated through oxygen, nitrogen or sulfur atoms is presented. Our aim was to compare and contrast O‐, N‐ and S‐chelated ruthenium complexes to better understand the impact of electron‐withdrawing and ‐donating substituents on the geometry and activity of the ruthenium complexes and to gain further insight into the trans–cis isomerisation process of the S‐chelated complexes. To evaluate the different effects of chelating heteroatoms and to probe electronic effects on sulfur‐ and nitrogen‐chelated latent catalysts, we synthesised a series of novel complexes. These catalysts were compared against two well‐known oxygen‐chelated initiators and a sulfoxide‐chelated complex. The structures of the new complexes have been determined by single‐crystal X‐ray diffraction and analysed to search for correlations between the structural features and activity. The replacement of the oxygen‐chelating atom by a sulfur or nitrogen atom resulted in catalysts that were inert at room temperature for typical ring‐closing metathesis (RCM) and cross‐metathesis reactions and showed catalytic activity only at higher temperatures. Furthermore, one nitrogen‐chelated initiator demonstrated thermo‐switchable behaviour in RCM reactions, similar to its sulfur‐chelated counterparts.
Synthesis of the Phenylpyridal Scaffold as a Helical Peptide Mimetic

Published: June 2010

AbstractPhenylpyridal‐ and phenyldipyridal‐based scaffolds have been designed and synthesized as novel helical peptide mimetics. The synthesis required optimisation and selective alkylation in producing 2,6‐functionalized 3‐hydroxypyridine derivatives for a convergent scheme. The pyridine analogues were coupled by a series of Suzuki/Stille types cross‐coupling reactions. A series of biaryl and ter‐aryl substituted heterocycles were produced. The synthetic approach was concise and high yielding allowing large variability at the wanted side‐chain attachment points. A number of compounds were synthesised to show the versatility of the strategy.
Hierarchical, Titania‐Coated, Carbon Nanofibrous Material Derived from a Natural Cellulosic Substance
Authors: Liu Xiaoyan , Gu Yuanqing , Huang Jianguo 
Published: June 2010

AbstractHierarchical, titania‐coated, nanofibrous, carbon hybrid materials were fabricated by employing natural cellulosic substances (commercial filter paper) as a scaffold and carbon precursor. Ultrathin titania films were firstly deposited by means of a surface sol–gel process to coat each nanofiber in the filter paper, and successive calcination treatment under nitrogen atmosphere yielded the titania–carbon composite possessing the hierarchical morphologies and structures of the initial paper. The ultrathin titania coating hindered the coalescence effect of the carbon species that formed during the carbonization process of cellulose, and the original cellulose nanofibers were converted into porous carbon nanofibers (diameters from tens to hundreds of nanometers, with 3–6 nm pores) that were coated with uniform anatase titania thin films (thickness ≈12 nm, composed of anatase nanocrystals with sizes of ≈4.5 nm). This titania‐coated, nanofibrous, carbon material possesses a specific surface area of 404 m2 g−1, which is two orders of magnitude higher than the titania–cellulose hybrid prepared by atomic layer deposition of titania on the cellulose fibers of filter paper. The photocatalytic activity of the titania–carbon composite was evaluated by the improved photodegradation efficiency of different dyes in aqueous solutions under high‐pressure, fluorescent mercury‐lamp irradiation, as well as the effective photoreduction performance of silver cations to silver nanoparticles with ultraviolet irradiation.
