Abstract

Background
The value of ultra-low coloanal anastomosis (CAA) for rectal cancer is dependent on the oncological and functional results. The aim of this comparative study was to evaluate the long-term oncological outcome of CAA with or without intersphincteric resection (ISR) for low-lying rectal tumours.

Methods
The study population comprised consecutive patients with low rectal cancer who underwent CAA in a single institution between 1977 and 2004. Patients were divided into two groups according to whether or not a partial ISR had been performed. Cox multivariate models were used for survival analysis.

Results
Some 278 patients underwent CAA with curative intent; 173 had ISR and 105 had CAA without ISR. Mean follow-up was 66·8 months. The 5-year actuarial rate for local recurrence, regardless of tumour stage, was 10·6 per cent in the ISR group versus 6·7 per cent for CAA alone (P = 0·405), and the 5-year actuarial overall survival rate was 86·1 and 80·0 per cent respectively (P = 0·318). Cox multivariable analysis revealed that resection of the anal canal was not a prognostic factor for local or metastatic recurrence.

Conclusion
Sphincter-preserving surgery appears to be oncologically adequate for very low-lying rectal tumours.

AbstractObjectives: We conducted a randomized trial to determine the efficacy of two topical hemostasis pads in promoting vascular hemostasis following PCI, and to assess the appropriate level of anticoagulation for sheath removal. Background: Pads coated with procoagulant materials are widely marketed and used to augment vascular hemostasis following PCI, yet clinical effectiveness and safety data are lacking. Methods: 184 patients who underwent PCI using the femoral approach were randomized to one of four methods of sheath removal: (1) at ACT < 250 using the Chito‐Seal™ pad; (2) at ACT < 250 using the Clo‐Sur PAD™; (3) at ACT < 250 using manual compression alone; (4) at ACT < 170 using manual compression alone. Results: Time to hemostasis was significantly shorter in the hemostasis pad groups compared to the conventional compression groups (16.2 ± 4.9, 16.0 ± 5.3, 19.3 ± 7.8, and 18.3 ± 5.7 min, respectively, P = 0.027), however overall bed rest times following intervention were not reduced by use of either hemostasis pad. The incidence of major or minor bleeding complications did not differ among groups. Irrespective of hemostasis pad use, removal of sheaths at higher ACT levels allowed shorter time to ambulation following PCI without an increase in bleeding events. Conclusions: The hemostasis pads tested shortened time to hemostasis compared to standard manual compression, although the absolute reduction in time to hemostasis was relatively small and did not translate into a reduction in overall bed rest time. Independent of hemostasis pad use, removal of arterial sheaths at higher than conventional activated clotting times was safe and resulted in significant reductions in time to ambulation. © 2006 Wiley‐Liss, Inc.

Association of platelet‐monocyte aggregates with platelet activation, systemic inflammation, and myocardial injury in patients with non‐st elevation acute coronary syndromes
Authors: Zhang Song‐Zhao , Jin Ya‐Ping , Qin Guang‐Ming , Wang Jun‐Hong 
Published: February 2007

AbstractBackgroundPlatelet‐monocyte aggregates (PMA) and C‐reactive protein (CRP) are increased in unstable coronary disease. The interrelation of PMA with platelet activation, systemic inflammation, and their association with markers of myocardial injury has not been studied extensively.HypothesisThe study was undertaken to evaluate the association of CRP, PMA, and cardiac troponin I (cTnI) in patients admitted with non‐ST elevation acute coronary syndromes (NSTE‐ACS).MethodsIn all, 69 consecutive patients with NSTE‐ACS, 58 patients with stable angina pectoris (SAP), and 46 control patients without coronary artery disease were selected; PMA, sP‐selectin, sCD40L inter leukin, (IL)‐6, CRP, and cTnI concentrations were measured in these patients at the time of admission. Patients with NSTE‐ACS were classified into two groups: those with troponin normal (cTnI < 0.06 ng/ml) and those with troponin elevation (cTnI ≥ 0.06 ng/ml). Their risk for clinical in‐hospital cardiac events (death and nonfatal myocardial infarction) was analyzed.ResultsCompared with SAP and control, patients with NSTE‐ACS exhibited higher levels of PMA, sP‐selectin, sCD40L, IL‐6, and CRP. All these parameters were found to be higher (p < 0.001 ) in patients with troponin elevation than in those with normal troponin. There was a significant relationship between PMA and CRP (r =0.628, p < 0.001) and cTnI (r = 0.557, p < 0.001) in patients with NSTE‐ACS. Logistic analysis further demonstrated that the presence of elevated PMA, CRP, and cTnI levels each confers and increases risk of future cardiac events.ConclusionsLevels of PMA and CRP were significantly increased in patients with NSTE‐ACS, especially in those with troponin elevation. This increase is strongly related to the risk of in‐hospital cardiac events. A panel of PMA, CRP, and cTnI may provide important information additional to current laboratory data for the treatment of NSTE‐ACS. Copyright © 2007 Wiley Periodicals, Inc.

AbstractBackgroundSuccessful prevention of aortic complications has lead to improved survival of Marfan syndrome (MFS). With increasing age, however, ventricular arrhythmia and heart failure are emerging as life‐threatening manifestations of myocardial dysfunction.HypothesisWe sought to investigate whether echocardiography with tissue Doppler imaging (TDI) identifies myocardial dysfunction in adults with MFS.MethodsWe performed two‐dimensional (2‐D) and Doppler echocardiography with TDI in 141 individuals with suspected MFS and competent heart valves, including 28 persons with MFS who had not undergone surgery and 86 healthy controls without inherited connective tissue disorders.ResultsDemographic profile, 2‐D, mitral and pulmonary venous flow indices, and left ventricular ejection fractions were similar in both groups. Conversely, isovolumic relaxation time (p < 0.001) and deceleration time of E velocity (p = 0.005) were longer, and atrial reversal velocities (p = 0.02), and systolic and early diastolic TD velocities were slower in MFS than in controls (p = 0.01). Multiple linear regression analysis excluded association of reduced systolic and early diastolic TD velocities with mitral valve prolapse or other clinical or echocardiographic features of MFS.ConclusionsOur study identifies reduced systolic and early diastolic TD velocities in adults with MFS. Further studies are mandatory to elucidate whether TD velocities predict arrhythmia and heart failure in MFS. Copyright © 2007 Wiley Periodicals, Inc.

AbstractBACKGROUND.The Fuhrman grading system is an established predictor of survival in patients with renal cell carcinoma (RCC). The predictive accuracy of various Fuhrman grading schemes was tested with the intent of improving the prediction of RCC‐specific survival (RCC‐SS).METHODS.The analyses targeted 5453 patients from 14 institutions. Univariable, multivariable, and predictive accuracy analyses addressed RCC‐SS. The statistical significance of the gain in predictive accuracy was quantified with the Mantel‐Haenszel test.RESULTS.The median follow‐up time was 4.5 years. In both univariable and multivariable analyses, Fuhrman grade achieved independent predictor status regardless of the coding scheme. When Fuhrman grade was not considered in multivariable analyses, the predictive accuracy was 83.8%. Addition of Fuhrman grade to the multivariable model resulted in predictive accuracy gains of 0.8% for all 3 grading schemes tested.CONCLUSION.Fuhrman grade must to be considered when RCC‐SS is assessed. However, modified or conventional Fuhrman grading schemes perform equally well as the conventional grading system. Cancer 2007 © 2007 American Cancer Society.
Kaposi sarcoma of the musculoskeletal system

Published: February 2007

AbstractKaposi sarcoma (KS) of bone and skeletal muscle is unusual. In this report, the authors review 66 published patients with KS who had involvement of the musculoskeletal system reported from 1925 to 2006. In only 3 patients was acquired immunodeficiency syndrome (AIDS)‐related KS identified within skeletal muscle. Osseous KS lesions were more frequent and occurred with African, classic, and AIDS‐related KS and occurred rarely in transplantation‐associated KS. Patients seldom were asymptomatic. They usually had bone pain with limited mobility or infrequently developed serious sequelae like spinal cord compression. Locally aggressive African and classic KS lesions typically involved the peripheral skeleton; whereas, in patients with AIDS, the axial (vertebrae, ribs, sternum, and pelvis) and/or maxillofacial bones more commonly were involved. Almost all patients had concomitant nonosseous KS lesions. Joint involvement was exceptional, and pathologic fractures were not observed. Computed tomography scans and magnetic resonance images were better at detecting osseous KS lesions, which frequently went undetected on plain x‐ray films or bone scans. Pathologic diagnosis was important to exclude similar lesions like bacillary angiomatosis. Treatment options, including surgery and, in more recent patients, radiation and/or chemotherapy, had limited success. Cancer 2007 © 2007 American Cancer Society.
Molecular Interactions in Poly(ethylene glycol)–Water Mixtures at Various Temperatures: Density and Isentropic Compressibility Study
Authors: Hanke Elke , Schulz Ulrike , Kaatze Udo 
Published: February 2007

AbstractThe densities and sound velocities of mixtures of water with poly(ethylene glycol), poly(ethylene glycol) monomethylether, and poly(ethylene glycol) dimethylether with mean molar weights between 250 and 500 have been measured as a function of mixture composition and temperature between 10 and 40 °C. Isentropic compressibilities are derived from the data and are compared to those for the ethylene glycol/water system and for other organic solvent/water mixtures. Relative minima in the mixture volume to ideal volume ratio and in the dependence of the compressibility upon mixture composition are discussed in terms of the conformational variability of the chainlike oligomers, of hydrogen‐bonded networks, and of water clusters between the oligomer chains.
A spatiotemporal evaluation of the contribution of the dorsal mesenchymal protrusion to cardiac development

Published: February 2007

AbstractThe mesenchymal tissues involved in cardiac septation are derived from different sources. In addition to endocardial‐derived mesenchyme, the heart also receives contributions from the neural crest, the proepicardium, and the dorsal mesenchymal protrusion (DMP). Whereas the contributions of the neural crest and proepicardium have been thoroughly studied, the DMP has received little attention. Here, we present the results of a comprehensive spatiotemporal study of the DMP in cardiac development. Using the Tie2‐Cre mouse, immunohistochemistry, and AMIRA reconstructions, we show that the DMP, in combination with the mesenchymal cap on the primary atrial septum, fuse with the major atrioventricular cushions to close the primary atrial foramen and to form the atrioventricular mesenchymal complex. In this complex, the DMP constitutes a discrete prominent mesenchymal component, wedged in between the major cushions. This new model for atrioventricular septation may provide novel insights into understanding the etiology of congenital cardiac malformations.

Eating disorders in diverse lesbian, gay, and bisexual populations
Authors: Feldman Matthew B. , Meyer Ilan H. 
Published: February 2007

AbstractObjective:This study estimates the prevalence of eating disorders in lesbian, gay, and bisexual (LGB) men and women, and examines the association between participation in the gay community and eating disorder prevalence in gay and bisexual men.Method:One hundred and twenty six white heterosexuals and 388 white, black, Latino LGB men and women were sampled from community venues. DSM‐IV diagnoses of anorexia, bulimia, and binge eating disorder were assessed using the World Health Organization's Composite International Diagnostic Interview.Results:Gay and bisexual men had significantly higher prevalence estimates of eating disorders than heterosexual men. There were no differences in eating disorder prevalence between lesbian and bisexual women and heterosexual women, or across gender or racial groups. Attending a gay recreational group was significantly related to eating disorder prevalence in gay and bisexual men.Conclusion:Researchers should study the causes of the high prevalence of eating disorders among gay and bisexual men. © 2007 by Wiley Periodicals, Inc.
