Concurrent and post-radiotherapy temozolomide (T) significantly improves survival in patient with newly diagnosed glioblastoma multiforme. We aimed to assess the activity of the combination of T and pegylated liposomal doxorubicin (PLD) in this population. A combination of T (days 1-5, 200 mg/m 2 orally) and PLD (day 1, 40 mg/m 2 intravenous) was given every 4 weeks for six cycles following chemo-radiotherapy as a post-operative treatment. The primary endpoint was 6-month progression free survival (6PFS). Of the 40 patients who enrolled (53 years median age, 73% male), the 6PFS was 58% (95% confidence interval [CI], 41-72%). The median time to progression was 6.2 months (95% CI, 5.6-8.0 months) and overall survival (OS) was 13.4 months (95% CI, 12.7-15.8 months). Thirty-four patients had measurable disease: one had a complete response (3%), 28 had stable disease (82%), and five had progressive disease (15%). Treatment was well tolerated: hematological toxicity included grade 3 neutropenia (8%). Grade 3 non-hematologic toxicity included nausea and vomiting (8%) and palmar-plantar toxicity (5%). We concluded that combination T and PLD is well tolerated but does not add significant clinical benefit regarding 6PFS and OS. © 2011 Published by Elsevier Ltd. All rights reserved.

Mutations affecting RAS genes are now established predictive markers of nonresponse to anti-EGFR antibodies in advanced CRC. This analysis assessed the prognostic and predictive impact of extended RAS and PIK3CA gene mutation status in patients receiving capecitabine plus or minus bevacizumab (mitomycin C) in the randomised phase III MAX study.DNA was extracted from archival macrodissected formalin-fixed paraffin-embedded tumour tissue. Mutation status was determined using pyrosequencing, confirmed with Sanger sequencing (for equivocal RAS) and correlated with efficacy outcomes. Predictive analyses were undertaken using a test for interaction involving both C vs CB+CBM.Of the available 280 of the 471 (59.4%) patients, mutations in KRAS exons 2, 3 and 4 and NRAS 2, 3 and 4 were as follows: 32%, 2.9%, 2.2%, 1.4%, 0.7% and 0% (total RAS MT 39%). The PIK3CA MT rate was 7.5% exon 9 and 3.6% exon 20. Extended RAS gene mutation status (WT vs MT) had no prognostic impact for PFS (HR 0.91 (0.71-1.17)) or OS (HR 0.95 (0.71-1.25)). The RAS gene mutation status was not predictive of the effectiveness of bevacizumab for PFS (HR 0.56 (0.37-0.85) for RAS MT and HR 0.69 (0.5-0.97) for RAS WT; P for interaction 0.50). The PIK3CA mutation was neither predictive for bevacizumab effect nor prognostic.Of KRAS exon 2 WT patients, 10% had additional RAS mutations. Neither all RAS gene mutation status nor PIK3CA mutation status was prognostic for PFS or OS, or predictive of bevacizumab outcome in patients with advanced CRC.

Purpose: We examined the feasibility and outcome of electromyographically triggered electrical muscle stimulation (EMG-ES) plus unilateral or bilateral task specific practice on arm function in chronic stroke survivors with moderate-severe hemiplegia. Transcranial magnetic stimulation was used to examine inter-hemispheric inhibition (IHI) acting on the stroke-affected hemisphere in a subset of eight participants. Methods: Twenty-one stroke survivors (14 males; mean time post stroke 57.9 months) participated in this pilot investigation. Participants underwent a six-week program of daily EMG-ES training with random assignment to concurrent task practice using the stroke-affected hand only or both hands. The upper-extremity subscale of the Fugl-Meyer (FMUE) and the Arm Motor Ability Test (AMAT) were completed at baseline, 0-, 1-, and 3-months post-intervention. Results: Following the intervention, FMUE (F(3, 57) = 3.89, p =.01, ηp2 =.17) and AMAT (F(3, 57) = 12.6, p =.01, ηp2 =.39) scores improved, and remained better than baseline at three months re-assessment. The difference between groups was not significant. A non-significant decrease in IHI was observed post-intervention. Conclusions: An intensive program of EMG-ES assisted functional training is feasible, well tolerated, and leads to improvements in moderate-severe deficits of arm function post stroke. Larger placebo controlled studies are needed to explore any advantage of bilateral over unilateral EMG-ES assisted training. © 2013-IOS Press and the authors.

Objective: To investigate if intravenous pamidronate improves bone density in a cohort of patients with chronic neurological conditions and low bone density, in whom fractures and bone pain are impacting on care. Methods: Fourteen participants (M:F = 7:7, average age 12.4 years) were enrolled in a prospective uncontrolled study in which pamidronate was infused every 68 weeks over a 2 year period, the average dose received was 12.5 mg kg-1. Results: Bone mineral density z-score improved at all sites measured over the 2 years; whole body -4.84 to -3.14 (p = 0.01), lumbar spine -2.92 to -1.1 (p = 0.02) and femoral neck -4.6 to -3.58 (p = 0.04). Of the eight patients with pain at baseline, seven reported decreased pain after 12 months of pamidronate. Of the 11 patients who answered the general wellbeing part of the questionnaire, eight patients reported an improvement in general wellbeing and three reported no change. There was a downward trend in the average annualized fracture rate from 0.42 to 0.14 fractures per year (p = 0.09). Conclusion: Pamidronate improves bone density and reduces pain in children and adolescents with chronic neurological conditions. © 2010 Informa UK Ltd All rights reserved.

Objective: To report on the presence and use of social media by speakers and attendees at the International Conference on Emergency Medicine (ICEM) 2012, and describe the increasing use of online technologies such as Twitter and podcasts in publicising conferences and sharing research findings, and for clinical teaching. Methods: Speakers were identified through the organising committee and a database constructed using the internet to determine the presence and activity of speakers on social media platforms. We also examined the use of Twitter by attendees and non-attendees using an online archiving system. Researchers tracked and reviewed every tweet produced with the hashtag #ICEM2012. Tweets were then reviewed and classified by three separate authors into different categories. Results: Of the 212 speakers at ICEM 2012, 41.5% had a LinkedIn account and 15.6% were on Twitter. Less than 1% were active on Google+ and less than 10% had an active website or blog. There were over 4500 tweets about ICEM 2012. Over 400 people produced tweets about the conference, yet only 34% were physically present at the conference. Of the original tweets produced, 74.4% were directly related to the clinical and research material of the conference. Conclusions: ICEM 2012 was the most tweeted emergency medicine conference on record. Tweeting by participants was common; a large number of original tweets regarding clinical material at the conference were produced. There was also a large virtual participation in the conference as multiple people not attending the conference discussed the material on Twitter.

Previous studies suggest that dairy intake may be associated with reduced bone and muscle loss with aging, but there are limited data in the very old. We evaluated the association between intake of dairy foods and peripheral bone structure and muscle mass in 564 elderly women aged 80 to 92 (mean 84.7) years, who were participants of the Calcium Intake Fracture Outcome Study/CAIFOS Aged Extension Study (CAIFOS/CARES) cohort and attended the 10-year follow-up. Assessments included dairy consumption (milk, yogurt, and cheese) by a validated food frequency questionnaire, 15% tibia bone mass, area and volumetric bone mineral density (vBMD) by peripheral quantitative computed tomography (pQCT), and appendicular bone and skeletal muscle mass by dual-energy X-ray absorptiometry (DXA). Women were categorized according to tertiles of dairy intake: first tertile (≤1.5 servings/d), second tertile (1.5 to 2.2 servings/d) and third tertile (≥2.2 servings/d). Controlling for confounding factors, pQCT assessment at the 15% tibia showed that compared with those in the first tertile of dairy intake, women in the third tertile had 5.7% greater total bone mass (p = 0.005), principally because of an increase in cortical and subcortical bone mass (5.9%, p = 0.050), resulting in a 6.2% increase in total vBMD (p = 0.013). Trabecular but not cortical and subcortical vBMD was also higher (7.8%, p = 0.044). DXA assessment showed that women in the third tertile of dairy intake had greater appendicular bone mass (7.1%, p = 0.007) and skeletal muscle mass (3.3%, p = 0.014) compared with tertile 1. The associations with bone measures were dependent on dairy protein and calcium intakes, whereas the association with appendicular muscle mass was not totally dependent on dairy protein intake. Our results suggest a positive association of dairy intake with appendicular bone mineralization and muscle mass in elderly women. Because many fractures in this age group are of the appendicular skeleton often associated with falls, dairy intake may be a modifiable lifestyle factor contributing to healthy aging. © 2014 American Society for Bone and Mineral Research.

Aim A retrospective audit was undertaken to evaluate modes of presentation and treatment outcomes for craniopharyngioma in a single paediatric institution over a 20-year period. Methods A search of the neurosurgical and histopathological databases for patients under 21 years of age treated for craniopharyngioma between 1990 and 2010 was performed at our institution. The clinical records of eligible patients were reviewed and information regarding presentation, medical and surgical management and post-treatment outcome were extracted and collated. Results Of 10 evaluable patients, the commonest presenting symptoms were headache and visual impairment. Clinical and biochemical evaluation undertaken prior to surgery revealed visual dysfunction in 70% and pituitary deficit in 30%. Gross total resection was achieved in 40% but was curative in only 20%. The remaining 80% required further surgical and/or radiotherapeutic intervention. Seven patients had radiation therapy with stabilisation in 70%. Multiple Pituitary Hormone Deficiency evolved in all patients over time, while visual impairment worsened in 30% post-operatively and improved in 20%. Obesity was present in 50% after a mean follow-up interval of 5.6 years and was apparent within 1 year of initial surgery in 30%. Although neurocognitive, psychological and behavioural problems were noted for some patients during medical review, only 20% of patients were formally assessed. Conclusions Craniopharyngioma is associated with significant long-term morbidity. Attention to an integrated care pathway that includes standardised neurocognitive and psychological and behavioural assessment would facilitate early appropriate intervention and support leading to an improved quality of life for children with craniopharyngioma. © 2013 Paediatrics and Child Health Division (Royal Australasian College of Physicians).

This commentary describes a student-led project that distributed long-lasting insecticide-treated nets in Masaka, Uganda. The role of student-led initiatives in global health promotion projects is also discussed.A survey of 213 net recipients was conducted after a 12-month period to evaluate malaria prevention knowledge, and net use and maintenance.Only 4.7% of recipients could not recall any malaria prevention methods. Seventy percent of pregnant women and 86.5% of children under five slept under a net the previous night. Only two households (0.9%) no longer possessed a net, and nets were not used in 2.3% of houses. Household observation revealed 17.4% of nets had at least one problem that would compromise effectiveness.Student-led projects can play an important role in effectively preventing malaria. However coordination with existing programs, targeting hard-to-access groups, and training of students overcomes some common limitations of such student-led initiatives.

Patients treated for colorectal cancer (CRC) experience considerable physical, social and psychological morbidity. In this study, 66 participants with stages I-III CRC were enrolled in this study. Participants completed the self-assessment tool for patients (SATp) over a 5-month period and visited a general practitioner with a copy of their SATp to assist in the management of any problems associated with CRC treatment. General practitioners notes were reviewed for management actions. Of the 66 participants, 57 visited a general practitioner over the 5-month study period. A total of 547 problems were identified (median 7; IQR: 3-12.25). Participants with physical problems were more likely to consult their general practitioner (OR: 1.84, CI: 1.05-3.21, P = 0.03) compared to those with psychological problems. The number of problems experienced by participants did not have any influence on the decision to visit a general practitioner. Psychological problems (P < 0.01) significantly reduced over the 5-month study period. Regular use of the SATp facilitates the identification of long-term CRC treatment-related problems. Some of these problems could then be addressed in primary care.

Treatment for colorectal cancer (CRC) may result in physical, social, and psychological needs that affect patients quality of life post-treatment. A comprehensive assessment should be conducted to identify these needs in CRC patients post treatment, however, there is a lack of tools and processes available in general practice.This study aimed to develop a patient-completed needs screening tool that identifies potentially unmet physical, psychological, and social needs in CRC and facilitates consultation with a general practitioner (GP) to address these needs.The development of the self-assessment tool for patients (SATp) included a review of the literature; face and content validity with reference to an expert panel; psychometric testing including readability, internal consistency, and test-retest reliability; and usability in clinical practice.The SATp contains 25 questions. The tool had internal consistency (Cronbachs alpha 0.70-0.97), readability (reading ease 82.5%), and test-retest reliability (kappa 0.689-1.000). A total of 66 patients piloted the SATp. Participants were on average 69.2 (SD 9.9) years old and had a median follow-up period of 26.7 months. The SATp identified a total of 547 needs (median 7 needs/per patient; IQR [3-12.25]). Needs were categorised into social (175[32%]), psychological (175[32%]), and physical (197[36%]) domains.SATp is a reliable self-assessment tool useful for identifying CRC patient needs. Further testing of this tool for validity and usability is underway.
