    The prevalence of lymphoedema in women who attended an information and exercise class to reduce the risk of breast cancer-related upper limb lymphoedema (2016)
    SpringerOpen
    Details
    Publication Date: 2016-01-08
    Description: Breast cancer-related upper limb lymphoedema (BCRL) affects approximately 20 % of women undergoing axillary intervention. Women who attended a “reducing your risk of lymphoedema” class, including exercise instruction, anecdotally reported positive BCRL outcomes. The aim of this study was to examine BCRL outcomes and perceived benefit for attendees at a “reducing your risk of lymphoedema” class between 2000 and 2005. A cross-sectional study was conducted in two parts: (1) self-report questionnaire regarding lymphoedema status and benefit received from class and exercise programme; (2) clinical evaluation and objective measurement to confirm BCRL. 46 women completed questionnaires; 40 continued to clinical evaluation and objective measurement. BCRL prevalence defined as ≥10 % excess limb volume was only 5 %, although clinician judgement identified 23 % with arm lymphoedema and 8 % with lymphoedema limited to the hand. Clinician judgement correlated highly with patient self-report (Kappa = 0.833, p = 0.000). All women found the class beneficial, reporting increased confidence to return to normal life and a wide range of activities/exercise. We conclude that prevalence of BCRL should be determined by both clinical judgement and objective measurement to avoid underestimation. The benefit of group education with a lymphoedema expert and of exercise instruction should be further explored, and the potential for exercise to reduce BCRL prevalence should be examined.

    Cerebellum activation associated with performance change but not motor learning (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-06-18
    Description: The issue of whether the cerebellum contributes to motor skill learning is controversial, principally because of the difficulty of separating the effects of motor learning from changes in performance. We performed a functional magnetic resonance imaging investigation during an implicit, motor sequence-learning task that was designed to separate these two processes. During the sequence-encoding phase, human participants performed a concurrent distractor task that served to suppress the performance changes associated with learning. Upon removal of the distractor, participants showed evidence of having learned. No cerebellar activation was associated with the learning phase, despite extensive involvement of other cortical and subcortical regions. There was, however, significant cerebellar activation during the expression of learning; thus, the cerebellum does not contribute to learning of the motor skill itself but is engaged primarily in the modification of performance.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seidler, R D -- Purushotham, A -- Kim, S-G -- Ugurbil, K -- Willingham, D -- Ashe, J -- NS40106/NS/NINDS NIH HHS/ -- RR08079/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2002 Jun 14;296(5575):2043-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brain Sciences Center (11B), Veterans Affairs Medical Center, Minneapolis, MN 55417, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12065841" target="_blank"〉PubMed〈/a〉

    The genomic and transcriptomic architecture of 2,000 breast tumours reveals novel subgroups (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-04-24
    Description: The elucidation of breast cancer subgroups and their molecular drivers requires integrated views of the genome and transcriptome from representative numbers of patients. We present an integrated analysis of copy number and gene expression in a discovery and validation set of 997 and 995 primary breast tumours, respectively, with long-term clinical follow-up. Inherited variants (copy number variants and single nucleotide polymorphisms) and acquired somatic copy number aberrations (CNAs) were associated with expression in ~40% of genes, with the landscape dominated by cis- and trans-acting CNAs. By delineating expression outlier genes driven in cis by CNAs, we identified putative cancer genes, including deletions in PPP2R2A, MTAP and MAP2K4. Unsupervised analysis of paired DNA-RNA profiles revealed novel subgroups with distinct clinical outcomes, which reproduced in the validation cohort. These include a high-risk, oestrogen-receptor-positive 11q13/14 cis-acting subgroup and a favourable prognosis subgroup devoid of CNAs. Trans-acting aberration hotspots were found to modulate subgroup-specific gene networks, including a TCR deletion-mediated adaptive immune response in the 'CNA-devoid' subgroup and a basal-specific chromosome 5 deletion-associated mitotic network. Our results provide a novel molecular stratification of the breast cancer population, derived from the impact of somatic CNAs on the transcriptome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3440846/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3440846/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Curtis, Christina -- Shah, Sohrab P -- Chin, Suet-Feung -- Turashvili, Gulisa -- Rueda, Oscar M -- Dunning, Mark J -- Speed, Doug -- Lynch, Andy G -- Samarajiwa, Shamith -- Yuan, Yinyin -- Graf, Stefan -- Ha, Gavin -- Haffari, Gholamreza -- Bashashati, Ali -- Russell, Roslin -- McKinney, Steven -- METABRIC Group -- Langerod, Anita -- Green, Andrew -- Provenzano, Elena -- Wishart, Gordon -- Pinder, Sarah -- Watson, Peter -- Markowetz, Florian -- Murphy, Leigh -- Ellis, Ian -- Purushotham, Arnie -- Borresen-Dale, Anne-Lise -- Brenton, James D -- Tavare, Simon -- Caldas, Carlos -- Aparicio, Samuel -- A7199/Cancer Research UK/United Kingdom -- P50HG02790/HG/NHGRI NIH HHS/ -- Cancer Research UK/United Kingdom -- England -- Nature. 2012 Apr 18;486(7403):346-52. doi: 10.1038/nature10983.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Oncology, University of Cambridge, Hills Road, Cambridge CB2 2XZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22522925" target="_blank"〉PubMed〈/a〉
