Testicular microlithiasis predicts concurrent testicular germ cell tumors and intratubular germ cell neoplasia of unclassified type in adults
Authors: Tan Iain B. , Ang Kai K. , Ching Boon C. , Mohan Chandra , Toh Chee K. , Tan Min H. 
Published: June 2010

AbstractBACKGROUND:There is an increasing body of literature associating testicular microlithiasis (TM), a common finding on testicular ultrasound, with testicular germ cell tumor (TGCT) and intratubular germ cell neoplasia of unclassified type (ITGCNU). Determining these associations is pertinent both clinically and biologically. To the authors' knowledge, no previous systematic review or meta‐analysis has been performed.METHODS:A comprehensive systematic literature review was performed without language restrictions through July 2009 and included an exhaustive search of electronic databases and article references. Two reviewers extracted data independently. Studies were categorized according to the clinical context in which sonography was performed. The primary study outcomes were concurrent diagnoses of TGCT or ITGCNU, with TM. In addition, studies with prospective follow‐up of patients with TM were reviewed.RESULTS:Thirty‐three studies met inclusion criteria. TM was not associated with an increased risk of TGCT in asymptomatic men. However, in referral populations, TM was associated overall with a risk ratio of 8.5 (95% confidence interval [CI], 4.5‐16.1; P < .001) for a concurrent diagnosis of TGCT and 10.5 (95% CI, 5.3‐20.8; P < .0001) for ITGCNU. Seventeen observational studies were identified in which the interval development of TGCT in patients with TM was reported; however, the majority of those studies did not report the follow‐up of a control arm and could not be summarized.CONCLUSIONS:In the presence of risk factors, TM was associated with a substantially elevated risk of a concurrent diagnosis of TGCT and ITGCNU. The authors suggest modifications to recently proposed guidelines for the management of TM. Cancer 2010. © 2010 American Cancer Society.

Published: June 2010

AbstractBACKGROUND:Regional differences in health services can point to disparities in access to healthcare. The authors performed a population‐based cohort study to examine differences in ovarian cancer treatment and mortality according to geographic region.METHODS:The Surveillance, Epidemiology, and End Results (SEER)‐Medicare database was used to identify 4589 women aged ≥65 years with ovarian cancer diagnosed between 1998 and 2002 who had Medicare claims filed from 1998 to 2005. Hospital Referral Region (HRR) was assigned according to patient zip code. The authors calculated the proportion of women in each HRR who underwent cancer‐directed surgery. With HRR as the predictor of interest, mortality and the receipt of cancer‐directed surgery were described in multivariate analyses.RESULTS:Among 4589 women with ovarian cancer, 3286 underwent cancer‐directed surgery. The receipt of cancer‐directed surgery varied by HRR (range, 53%‐88%). Women were less likely to undergo cancer‐directed surgery if they were older, nonwhite, had higher stage disease, or had more comorbidities. For example, white women were more likely to undergo such surgery (odds ratio, 1.41; 95% confidence interval, 1.10‐1.82) compared with all nonwhite women. HRR was a significant predictor of cancer‐directed surgery (P = .01). A significant correlation was observed between HRR and all‐cause mortality (P = .02); however, after adjusting for cancer‐directed surgery, that correlation was no longer significant (P = .10).CONCLUSIONS:There was regional variation in mortality among Medicare recipients with ovarian cancer, and access to cancer‐directed surgery explained some of that variation. Improving access to high‐quality cancer surgery for ovarian cancer may improve outcomes, particularly for minorities and for older women. Cancer 2010. © 2010 American Cancer Society.
Characteristics of patients with stage III colon adenocarcinoma who fail to receive guideline‐recommended treatment

Published: June 2010

AbstractBACKGROUND:Many patients with stage III colon adenocarcinoma do not receive adjuvant chemotherapy despite the proven survival advantage it offers. To enhance the provision of optimal cancer care, patient characteristics associated with not receiving guideline‐adherent treatment must be identified among patients with operable, stage III colon adenocarcinoma.METHODS:This was a population‐based, retrospective study of all patients who underwent surgery for stage III colon adenocarcinoma diagnosed from 2002 through 2005 in Alberta, Canada. Demographic and treatment information captured in the Alberta Cancer Registry were linked to: 1) hospital discharge data to determine comorbidities, 2) electronic medical records to identify consults with oncologists, and 3) the 2001 Canadian census for neighborhood‐level socioeconomic data. Multivariate log‐binomial regression models were used to identify patient characteristics that were associated with not having a consultation with a medical oncologist and not receiving adjuvant chemotherapy.RESULTS:Of the 772 patients who underwent surgery for stage III colon adenocarcinoma and met the eligibility criteria, 618 patients (80%) had a consultation with an oncologist. Of those, 388 patients (63%) initiated adjuvant chemotherapy within 84 days of their surgery. Patient characteristics that were associated with not having a consultation with an oncologist were neighborhood income, geography, age, and comorbidities. Of those patients who had a consultation, after adjusting for comorbidities, only older age was related to not receiving adjuvant chemotherapy.CONCLUSIONS:The current results indicated that the proportion of patients with stage III colon adenocarcinoma who did not receive treatment according to evidence‐based guidelines was appreciable. The authors concluded that the association of this failure with patient age, geography, and income is concerning and that evaluation of referral patterns and interventions are needed.

AbstractBACKGROUND:Endometrial cancer (EC) is a common malignancy worldwide. It is often preceded by endometrial hyperplasia, whose management and risk of neoplastic progression vary. Previously, the authors have shown that the tetraspan protein epithelial membrane protein‐2 (EMP2) is a prognostic indicator for EC aggressiveness and survival. Here the authors validate the expression of EMP2 in EC, and further examine whether EMP2 expression within preneoplastic lesions is an early prognostic biomarker for EC development.METHODS:A tissue microarray (TMA) was constructed with a wide representation of benign and malignant endometrial samples. The TMA contains a metachronous cohort of cases from individuals who either developed or did not develop EC. Intensity and frequency of EMP2 expression were assessed using immunohistochemistry.RESULTS:There was a stepwise, statistically significant increase in the average EMP2 expression from benign to hyperplasia to atypia to EC. Furthermore, detailed analysis of EMP2 expression in potentially premalignant cases demonstrated that EMP2 positivity was a strong predictor for EC development.CONCLUSIONS:EMP2 is an early predictor of EC development in preneoplastic lesions. In addition, combined with our previous findings, these results validate EMP2 as a novel biomarker for EC development. Cancer 2010. © 2010 American Cancer Society.

AbstractBACKGROUND:A study was undertaken to analyze the survival of chronic lymphocytic leukemia (CLL) patients relative to age‐matched individuals in the general population and determine the age‐stratified utility of prognostic testing.METHODS:All 2487 patients diagnosed with CLL between January 1995 and June 2008 and cared for in the Mayo Clinic Division of Hematology were categorized by age at diagnosis and evaluated for differences in clinical characteristics, time to first treatment, and overall survival (OS).RESULTS:Among Rai stage 0 patients, survival was shorter than the age‐matched general population for patients aged <55 years (P < .001), 55 to 64 years (P < .001), and 65 to 74 years (P < .001), but not those aged ≥75 years at diagnosis (P = not significant). CD38, IGHV mutation, and ZAP‐70 each predicted time to first treatment independent of stage for all age groups (all P < .04), but had less value for predicting OS, particularly as age increased. IGHV and fluorescent in situ hybridization (FISH) predicted OS independent of stage for patients aged <55 years (P ≤ .001), 55 to 64 years (P ≤ .004), and 65 to 74 years (P ≤ .001), but not those aged ≥75 years. CD38 and ZAP‐70 each predicted OS independent of stage for only 2 of 4 age categories. Among Rai 0 patients aged <75 years, survival was shorter than the age‐matched population only for IGHV unmutated (P < .001) patients or those with unfavorable FISH (P < .001).CONCLUSIONS:Survival of CLL patients aged <75 years is shorter than the age‐matched general population regardless of disease stage. Among patients aged <75 years, the simple combinations of stage and IGHV or stage and FISH identifies those with excess risk of death relative to the age‐matched population. Although useful for predicting time to first treatment independent of stage for patients of all ages, prognostic testing had little utility for predicting OS independent of stage among patients aged ≥75 years.

Building dynamic and transparent integrity measurement and protection for virtualized platform in cloud computing
Authors: Cheng Ge , Jin Hai , Zou Deqing , Zhang Xinwen 
Published: June 2010

AbstractIn the cloud computing infrastructure, there is an increasing demand to maintain and verify the integrity of software stacks running on remote systems and protect users' sensitive data. However, due to the fact that software stacks running on cloud platforms are usually provided and maintained by different authorities (or providers) who are potentially untrusting to each other, the problem of measuring and protecting runtime system integrity becomes very challenging and has not been well addressed yet. In this paper, we present an integrity measurement and protection architecture for software stacks running on a guest operating system (OS) of a virtualized platform in cloud environment. Our solution does not change the guest OS, and thus is transparent to the OS authority. Furthermore, our architecture ensures that sensitive information of users is protected once the integrity of software stacks is broken during runtime. We implement our solution on Xen, and present a simple prototype‐based Nimbus. We demonstrate the capability of dynamically detecting the integrity change of programs in cloud computing, and our evaluation results show that the solution is effective for integrity protection with acceptable performance overhead.

Expression of Gpr177, a Wnt trafficking regulator, in mouse embryogenesis
Authors: Yu Hsiao‐Man Ivy , Jin Ying , Fu Jiang , Hsu Wei 
Published: June 2010

AbstractWls/Evi/Srt encoding a multipass transmembrane protein has been identified as a regulator for proper sorting and secretion of Wnt in flies. We have previously demonstrated that Gpr177 is the mouse ortholog required for axis determination. Gpr177 is a transcriptional target of Wnt that is activated to assist its subcellular distribution in a feedback regulatory loop. We, therefore, proposed that reciprocal regulation of Wnt and Gpr177 is essential for the Wnt‐dependent developmental and pathogenic processes. Here, we examine the expression pattern of Gpr177 in mouse development. Gpr177 is expressed in a variety of tissues and cell types during organogenesis. Furthermore, Gpr177 is a glycoprotein primarily accumulating in the Golgi apparatus in signal‐producing cells. The glycosylation of Gpr177 is necessary for proper transportation in the secretory pathway. Our findings suggest that the Gpr177‐mediated regulation of Wnt is crucial for organogenesis in health and disease. Developmental Dynamics 239:2102–2109, 2010. © 2010 Wiley‐Liss, Inc.
Mesenchymal cell remodeling during mouse secondary palate reorientation
Authors: Jin Jiu‐Zhen , Tan Min , Warner Dennis R. , Darling Douglas S. , Higashi Yujiro , Gridley Thomas , Ding Jixiang 
Published: June 2010

AbstractThe formation of mammalian secondary palate requires a series of developmental events such as growth, elevation, and fusion. Despite recent advances in the field of palate development, the process of palate elevation remains poorly understood. The current consensus on palate elevation is that the distal end of the vertical palatal shelf corresponds to the medial edge of the elevated horizontal palatal shelf. We provide evidence suggesting that the prospective medial edge of the vertical palate is located toward the interior side (the side adjacent to the tongue), instead of the distal end, of the vertical palatal shelf and that the horizontal palatal axis is generated through palatal outgrowth from the side of the vertical palatal shelf rather than rotating the pre‐existing vertical axis orthogonally. Because palate elevation represents a classic example of embryonic tissue re‐orientation, our findings here may also shed light on the process of tissue re‐orientation in general.

Jarid2 is among a set of genes differentially regulated by Nkx2.5 during outflow tract morphogenesis

Published: June 2010

AbstractNkx2.5, a transcription factor implicated in human congenital heart disease, is required for regulation of second heart field (SHF) progenitors contributing to outflow tract (OFT). Here, we define a set of genes (Lrrn1, Elovl2, Safb, Slc39a6, Khdrbs1, Hoxb4, Fez1, Ccdc117, Jarid2, Nrcam, and Enpp3) expressed in SHF containing pharyngeal arch tissue whose regulation is dependent on Nkx2.5. Further investigation shows that Jarid2, which has been implicated in OFT morphogenesis, is a direct target of Nkx2.5 regulation. Jarid2 expression was up‐regulated in SHF mesoderm of Nkx2.5‐deficient embryos. Chromatin immunoprecipitation analysis showed Nkx2.5 interaction with consensus binding sites in the Jarid2 promoter in pharyngeal arch cells. Finally, Jarid2 promoter activity and mRNA expression levels were down‐regulated by Nkx2.5 overexpression. Given the role of Jarid2 as a regulator of early cardiac proliferation, these findings highlight Jarid2 as one of several potential mediators of the critical role played by Nkx2.5 during OFT morphogenesis.

AbstractMyxoid degeneration of the cardiac valves is a common feature in a heterogeneous group of disorders that includes Marfan syndrome and isolated valvular diseases. Mitral valve prolapse is the most common outcome of these and remains one of the most common indications for valvular surgery. While the etiology of the disease is unknown, recent genetic studies have demonstrated that an X‐linked form of familial cardiac valvular dystrophy can be attributed to mutations in the Filamin‐A gene. Since these inheritable mutations are present from conception, we hypothesize that filamin‐A mutations present at the time of valve morphogenesis lead to dysfunction that progresses postnatally to clinically relevant disease. Therefore, by carefully evaluating genetic factors (such as filamin‐A) that play a substantial role in MVP, we can elucidate relevant developmental pathways that contribute to its pathogenesis. In order to understand how developmental expression of a mutant protein can lead to valve disease, the spatio‐temporal distribution of filamin‐A during cardiac morphogenesis must first be characterized. Although previously thought of as a ubiquitously expressed gene, we demonstrate that filamin‐A is robustly expressed in non‐myocyte cells throughout cardiac morphogenesis including epicardial and endocardial cells, and mesenchymal cells derived by EMT from these two epithelia, as well as mesenchyme of neural crest origin. In postnatal hearts, expression of filamin‐A is significantly decreased in the atrioventricular and outflow tract valve leaflets and their suspensory apparatus. Characterization of the temporal and spatial expression pattern of filamin‐A during cardiac morphogenesis is a crucial first step in our understanding of how mutations in filamin‐A result in clinically relevant valve disease.
