Abstract
BACKGROUND Children with speech sound disorders (SSD) form a heterogeneous group who differ in terms of the severity of their condition, underlying cause, speech errors, involvement of other aspects of the linguistic system and treatment response. To date there is no universal and agreed-upon classification system. Instead, a number of theoretically differing classification systems have been proposed based on either an aetiological (medical) approach, a descriptive-linguistic approach or a processing approach. AIMS To describe and review the supporting evidence, and to provide a critical evaluation of the current childhood SSD classification systems. METHODS & PROCEDURES Descriptions of the major specific approaches to classification are reviewed and research papers supporting the reliability and validity of the systems are evaluated. MAIN CONTRIBUTION Three specific paediatric SSD classification systems; the aetiologic-based Speech Disorders Classification System, the descriptive-linguistic Differential Diagnosis system, and the processing-based Psycholinguistic Framework are identified as potentially useful in classifying children with SSD into homogeneous subgroups. The Differential Diagnosis system has a growing body of empirical support from clinical population studies, across language error pattern studies and treatment efficacy studies. The Speech Disorders Classification System is currently a research tool with eight proposed subgroups. The Psycholinguistic Framework is a potential bridge to linking cause and surface level speech errors. CONCLUSIONS & IMPLICATIONS There is a need for a universally agreed-upon classification system that is useful to clinicians and researchers. The resulting classification system needs to be robust, reliable and valid. A universal classification system would allow for improved tailoring of treatments to subgroups of SSD which may, in turn, lead to improved treatment efficacy.

Abstract
Abstract
Background: Only half of HER2-positive metastatic breast cancer patients will respond to first-line trastuzumab-containing therapy, but of these, most will progress within a year. Trastuzumab resistance remains a continuing clinical problem, and better biomarkers and therapies are needed. Activin A is a TGF-beta superfamily member that regulates cell proliferation, apoptosis, differentiation, and immune response. We have previously reported that higher pretreatment serum activin A level predicted reduced progression-free survival (PFS) and overall survival (OS) to first-line trastuzumab, independent of age, line of therapy, CA 15–3, and hormone receptor status (ASCO Ab ID 607, 2012).
Methods: Serum activin A was measured using ELISA (R&D Systems, Minneapolis, MN) in 60 metastatic breast cancer patients before and 1 month after starting first-line trastuzumab-containing therapy. PFS and OS were analyzed using the Kaplan-Meier method and Cox modeling with both continuous and dichotomous (median) serum activin A analyses.
Results: Pretreatment serum activin A levels had a median of 629 pg/mL and an inter-quartile range of 406 to 1791 pg/mL. There was no significant change in activin A levels between pretreatment and one month after starting trastuzumab therapy. Median activin A level at one month was 655 pg/mL, with an inter-quartile range of 405 to 1517 pg/mL. 83% of patients who had low pretreatment activin A levels (below median) had low activin levels at one month, and 83% who had high activin levels (above median) at baseline had high activin A levels at one month. Patients who had high activin A levels at baseline and one month had the worst outcome for both PFS (HR 3.9; median 134 days vs.776 days; p < 0.0001) and OS (HR 6.7; p < 0.0001) when compared to patients with low activin A levels which remained low at one month.
Conclusions: Higher pretreatment and 1 month post-treatment serum activin A predicted for reduced PFS and overall survival in metastatic breast cancer patients treated with first-line trastuzumab-containing therapy. Trastuzumab-based therapy did not have a significant effect on activin A levels at one month. Patients with persistently high activin A levels had significantly worsened outcomes compared to those with low activin A levels. Serum activin A deserves further study to select patients most likely to respond to activin A-targeted therapy.

Abstract
The knowledge that our bodies are home to microbes is not new; van Leeuwenhoek first saw the microbes of the mouth and gut over three centuries ago. However, next generation sequencing technologies are enabling us to characterize our microbial consortia on an unprecedented scale, and are providing new insights into the range of variability of our microbiota and their contributions to our health. The microbiota far outnumber the human component of our selves, with 10 times more cells and at least 100 times more genes. Moreover, while individuals share over 99.9% of their human genome sequence, there are vast differences in the microbiome (the collection of genes of our associated microbes). This raises the question of the extent to which our microbial community determines our human physiological responses and susceptibility to disease. In order to develop technologies that allow us to manipulate the microbiome to improve health we must first understand the factors that influence spatial and temporal variation, stability in response to perturbation, and conditions that induce community-wide changes.

Abstract
AIM To conduct a pilot randomised controlled trial of mobile phone-based smoking cessation support intervention for the UK population. DESIGN Randomised controlled trial (txt2stop). SETTING Community. PARTICIPANTS 200 participants responding to radio, poster and leaflet-based promotions regarding the trial. MAIN OUTCOME MEASURES The response rate for the outcome measures planned for the main trial. Participants' qualitative responses to open-ended questions about the intervention content. Secondary outcomes were the outcomes planned for the main trial including the point prevalence of self-reported smoking at 4 weeks and pooled effect estimate for the short-term results for the STOMP and txt2stop trials. RESULTS The response rate at 4 weeks was 96% and at 6 months was 92%. The results at 4 weeks show a doubling of self-reported quitting relative risk (RR) 2.08 (95% CI 1.11 to 3.89), 26% vs 12%. The pooled effect estimate combining txt2stop and a previous New Zealand trial in the short term is RR 2.18 (95% CI 1.79 to 2.65). CONCLUSIONS Mobile phone-based smoking cessation is an innovative means of delivering smoking cessation support, which doubles the self-reported quit rate in the short term. It could represent an important, but as yet largely unused, medium to deliver age-appropriate public health measures. The long-term effect of this mobile phone-based smoking cessation support will be established by a large randomised controlled trial currently in recruitment.

Abstract
This study compares the perceptions of transplant surgery program directors (PDs) and recent fellowship graduates (RFs) regarding the adequacy of training and relevancy to practice of specific curricular content items in fellowship training. Surveys were sent to all American Society of Transplant Surgery approved fellowship PDs and all RFs in practice <5 years. For operative procedures, the RFs considered the overall training to be less adequate than the PDs (p = 0.0117), while both groups considered the procedures listed to be relevant to practice (p = 0.8281). Regarding nonoperative patient care items, although RFs tended to rank many individual items lower, both groups generally agreed that the training was both adequate and relevant. For nonpatient care related items (i.e. transplant-related ethics, economics, research, etc.), both groups scored them low regarding their adequacy of training although RFs scored them significantly lower than PDs (p = 0.0006). Regarding their relevance to practice, while both groups considered these items relevant, RFs generally considered them more relevant than PDs. Therefore, although there is consensus on many items, significant differences exist between PDs and RFs regarding their perceptions of the adequacy of training and the relevance to practice of specific curriculum items in transplant surgery fellowship training.

Abstract
8536 Background: Lenalidomide (Revlimid, Len), bortezomib (VELCADE, Bz; maximum tolerated dose [MTD] 15 mg/1.0 mg/m2) ± dexamethasone (Dex; 20–40 mg; RVD) was well tolerated in a phase I study in relapsed/refractory MM patients (pts), with 58% ≥MR. This multicenter phase 2 study evaluated RVD efficacy and safety at the MTD. Methods: Patients received up to eight 21-day cycles of Len 15 mg (days 1–14), Bz 1.0 mg/m2 (days 1, 4, 8, 11), and Dex 40/20 mg (cycles 1–4/5–8, days of/after Bz dosing). After cycle 8, patients with stable/responding disease received maintenance (Len, days 1–14; Bz, days 1, 8; doses per end of cycle 8; Dex 10 mg, days 1, 2, 8, 9) until progression or unacceptable toxicity. Pts with significant peripheral neuropathy were excluded. Results: Among 64 pts, 38 (59%) had relapsed and 26 (41%) refractory/relapsed MM. Median number of prior therapies was two, including Len (8%), Bz (55%), Dex (92%), thalidomide (77%), and stem cell transplant (SCT, 36%). Forty-one pts (64%) completed 8 cycles, 33 continue on maintenance, 22 discontinued early (11 due to progressive disease). Toxicities were manageable, primarily grade (G) 1/2 myelosuppression; 2 developed DVT on aspirin, 2 G3 atrial fibrillation, 1 G3 peripheral neuropathy. One pt died on-study (fungal pneumonia, possibly due to Dex). Overall response rate (62 evaluable patients) was 84% ≥MR, including 21% CR/nCR, 68% ≥PR, which was independent of high-risk features and prior treatment ( Table ). Median duration of response is 24 weeks (range 6–81). Time-to-events data including median time to progression, progression-free survival, and 1-year survival rates will be presented. Conclusions: RVD is active and well tolerated in pts with relapsed/refractory MM, including pts who have received prior Len, Bz, thalidomide, and SCT. Durable responses have been observed and appear independent of adverse cytogenetics and other recognized risk factors. [Table: see text] [Table: see text]
