Reading for Meaning: The Influence of Reader Characteristics on Paragraph Understanding in Aphasia.

PURPOSE: The study improves our understanding of the reading comprehension difficulties seen in people with aphasia. It investigates the influence of reader characteristics, including personal demographic variables, and linguistic and wider cognitive skills, on text comprehension. METHOD: Seventy-five people with aphasia and 87 neurologically typical readers completed a test of paragraph comprehension. People with aphasia also completed background tests of language, attention, recognition memory, and executive functions. The influence of demographic variables (age, gender, and level of education) was analyzed separately in the group of people with aphasia and the typical readers using analyses of variance. In the people with aphasia, the relationship between paragraph comprehension and the language and cognitive tests was explored using correlational analyses. RESULTS: In the typical readers, there was a significant effect of gender and level of education and a significant three-way interaction. For the people with aphasia, there were no significant effects of demographic variables. Significant positive correlations were found between performance on paragraph comprehension and each of the language tests and with tests of auditory attention, executive functions, and recognition memory for words. CONCLUSIONS: In people with aphasia, the effects of demographic variables were overshadowed by the effect of their language difficulties. The association seen across language measures reflects the shared semantic representations across single-word, sentence, and text levels, across modalities. The study emphasizes the importance of attention, executive functions, and short-term memory in the comprehension of and memory for what we read. The contribution of both language difficulties and wider cognitive skills needs to be considered when planning intervention. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.24695451.

Clinical trial: predictive factors for response to gut-directed hypnotherapy for refractory irritable bowel syndrome, a post hoc analysis.

BACKGROUND: Gut-directed hypnotherapy is effective for patients with irritable bowel syndrome (IBS). Despite its considerable evidence base, gut-directed hypnotherapy is not widely available and remains a limited resource. This emphasises the need to select patients who are most likely to benefit. AIM: To determine whether baseline patient characteristics were predictive of response to gut-directed hypnotherapy in patients with IBS METHODS: We conducted a secondary analysis of outcomes of 448 patients with refractory Rome III IBS who participated in a randomised study confirming non-inferiority of 6 compared to 12 sessions of gut-directed hypnotherapy. We compared baseline patient characteristics, including age, sex, IBS subtype, quality of life and IBS-Symptom Severity Scale (IBS-SSS), non-colonic symptom score and Hospital Anxiety and Depression (HAD) score between responders and non-responders. We defined response as ≥50-point decrease in IBS-SSS or ≥30% reduction in pain severity scores. RESULTS: Overall, 76.3% achieved ≥50-point decrease in IBS-SSS. Responders had a higher baseline non-colonic symptom score (p = 0.005). Those who achieved ≥30% improvement in abdominal pain scores (59.8%) had higher baseline IBS-SSS (p = 0.03), and lower baseline HAD-depression score (p = 0.012). Fifty-four patients (12%) dropped out of gut-directed hypnotherapy. Compared to completers, dropouts had higher baseline HAD-anxiety score (p = 0.034). CONCLUSIONS: These data suggest that patients with a higher burden of gastrointestinal and extraintestinal symptoms are most likely to benefit from gut-specific behavioural intervention for refractory IBS. Clinical assessment of gastrointestinal, somatic and psychological symptom profiles may play a role in selecting patients for gut-directed hypnotherapy.

Trends in engagement with cognitive-behavioral therapy for chronic pain conditions after referral.

Cognitive-behavioral therapy for chronic pain (CBT-CP) is an important evidence-based non-pharmacologic treatment for chronic back and neck pain that is frequently recommended as a component of multidisciplinary treatment. However, the success of CBP-CP's implementation in clinical settings is affected by a variety of poorly understood obstacles to patient engagement with CBT-CP. Expanding upon the limited prior research conducted in heterogeneous practice settings, this study examines patterns of treatment initiation for CBT-CP at an interdisciplinary, hospital-based chronic pain practice and conducts exploratory comparisons between groups of patients who did and did not engage in CBT-CP after receiving a referral. Patients' descriptive data, including pain severity, work status, prior therapy, and behavioral health questionnaire scores at intake visit, were obtained through a retrospective chart review of electronic medical records. Data were then analyzed using inter-group comparisons and logistic regression modeling to determine factors that predicted treatment initiation for CBT-CP. On multivariate analysis, we found that patient's depression level as measured by their Patient Health Questionnaire 9 (PHQ-9) score was solely predictive of treatment initiation, as chronic pain patients with a higher level of depression were found to be more likely to attend their recommended appointments of CBT-CP. Anxiety score as measured by GAD-7, work status, pain scores, and prior therapy engagement were not independently predictive. No single "profile" of patient-level factors was found to delineate patients who did and did not initiate CBT-CP, demonstrating the limitations of clinical variables as predictors of uptake.

Cognitive-behavioral therapy (CBT) is a frequently used therapy option, and can be helpful for patients with chronic low back and/or neck pain. However, patients do not always choose to engage in CBT when offered in the context of chronic pain. Reasons patients choose not to pursue CBT, when recommended, are not well understood. This study used data from a hospital-based chronic pain practice in order to identify reasons that patients choose to begin CBT and those who do not. Data about these patients was collected from electronic medical records (EMRs) and was used to conduct statistical analyses, with the goal of determining what factors were significantly different between the two groups of patients. We identified that patients who have more severe depression symptoms based on a specific mental health questionnaire (the Patient Health Questionnaire 9, or PHQ-9) were more likely to engage with CBT. Study results imply that patients without comorbid depression may benefit from additional counseling on the potential benefits of CBT in the management of chronic pain. These results also suggest that reasons other than clinical factors are impacting whether or not patients engage with CBT.

Prevention of lymphoedema after axillary clearance by external compression sleeves PLACE randomised trial results. Effects of high BMI.

Around 25% of women undergoing Axillary Clearance (ANC) develop lymphedema (LE). Intervention with a compression garment is recommended to prevent LE but no randomised evidence exists to support this strategy. METHODS: A randomised trial tested standard management versus application of graduated compression garments (20-24 mmHg) to affected arm, for 1 year. Women with node positive breast cancer (n = 1300) undergoing ANC consented to arm volume measurements and those developing a 4-9% relative arm volume increase (RAVI) (subclinical LE) within 9 months post-surgery were randomised. Primary outcome was proportion of patients developing LE (RAVI > 10%) by 24-months in each group. Secondary endpoints included Quality of life in each group. RESULTS: In total 143 patients were randomised (74 no sleeve: 69 compression sleeve) between October 2010 and November 2015. The lymphoedema rate at 24 months in the 'no sleeve' group was at 41%, similar to the 'sleeve' group (30%: p = 0.32). Thirtytwo patients randomised to the 'no sleeve' group had a sleeve applied within 24 months. Body Mass Index (BMI) at randomisation predicted LE at any time point HR 1.04 (CI 1.01-1.08; p = 0.01). Patients with obesity (BMI > 30) had higher rates of LE in both groups (46%) compared to those with BMI < 30 (24%). No difference between patients was found in either group in changes in QoL. Compression sleeves applied after development of LE improved QoL scores (FACT-B p = 0.007:TOI p = 0.042). CONCLUSION: Early intervention with External Compression garments does not prevent clinical LE, particularly in women with a high BMI > 30. The use of prophylactic garments in subclinical LE (RAVI < 9%) is unwarranted.

The effect of processing semantic features on spoken word retrieval in a case series of people with aphasia.

Purpose: There is a growing body of evidence showing the benefit of Semantic Feature Analysis in the treatment of word finding abilities in people with aphasia. The original technique was grounded in the hypothesis that the activation of semantic features spreads to the target and thereby facilitates its subsequent retrieval. However, it remains unclear the extent to which the focus on semantic features influences the treatment effects. The aim of this study was therefore to shed light on this issue by examining the effect of priming with semantic features (parts and functions) on target retrieval across a case series of people with aphasia.Method: 10 people with aphasia and word retrieval impairments were primed with spoken forms of words that were either the target name (identity condition, e.g. car), parts of the target (e.g. wheel) or functions of the target (e.g. drive) before later being asked to name a picture of that target. An unrelated prime condition (e.g. employ) was used as a control for test-retest effects.Result: At a group level, there was speeding of reaction times in picture naming in the identity condition relative to the unrelated condition; however, no effect of priming was found for either parts or functions. There was significantly better response accuracy in post-priming naming, but this effect did not reach significance for any individual experimental condition (identity, parts, functions) as compared to the unrelated condition, although the identity condition showed numerical improvement while the other two conditions showed decline.Conclusion: Given the lack of evidence for facilitatory effects from parts and functions of a target in a priming task, this research suggests that further research is warranted on the extent to which the improvement in word retrieval subsequent to Semantic Feature Analysis is caused by the emphasis on production of semantic features rather than from the repetition of the target name.

Protection and antibody levels 35 years after primary series with hepatitis B vaccine and response to a booster dose.

BACKGROUND AND AIMS: The duration of protection from hepatitis B vaccination in children and adults is not known. In 1981, we used three doses of plasma-derived hepatitis B vaccine to immunize a cohort of 1578 Alaska Native adults and children from 15 Alaska communities who were ≥6 months old. APPROACH AND RESULTS: We tested persons for antibody to hepatitis B surface antigen (anti-HBs) levels 35 years after receiving the primary series. Those with levels <10 mIU/ml received one booster dose of recombinant hepatitis B vaccine 2-4 weeks later and were then evaluated on the basis of anti-HBs measurements 30 days postbooster. Among the 320 recruited, 112 persons had not participated in the 22- or 30-year follow-up study (group 1), and 208 persons had participated but were not given an HBV booster dose (group 2). Among the 112 persons in group 1 who responded to the original primary series, 53 (47.3%) had an anti-HBs level ≥10 mIU/ml. Among group 1, 73.7% (28 of 38) of persons available for a booster dose responded to it with an anti-HBs level ≥10 mIU/ml at 30 days. Initial anti-HBs level after the primary series was correlated with higher anti-HBs levels at 35 years. Among 8 persons who tested positive for antibody to hepatitis B core antigen, none tested positive for HBsAg or HBV DNA. CONCLUSIONS: Based on anti-HBs level ≥10 mIU/ml at 35 years and a 73.7% booster dose response, we estimate that 86% of participants had evidence of protection 35 years later. Booster doses are not needed in the general population at this time.

Modifying dietary patterns in cardiothoracic transplant patients to reduce cardiovascular risk: The AMEND-IT Trial.

BACKGROUND: Cardiovascular disease (CVD) is common after cardiothoracic transplantation and causes substantial morbidity. AIMS: To assess feasibility and potential effectiveness of dietary interventions to reduce CVD risk. MATERIALS AND METHODS: In a pilot intervention, we recruited patients from a tertiary hospital and randomly allocated them to a Mediterranean or low-fat diet for 12 months. Feasibility was measured by patient participation, retention, and adherence. Changes in weight, body mass index (BMI), heart rate, blood pressure, glucose markers, and blood lipids were assessed using longitudinal generalized estimating equation regression models with 95% confidence intervals. RESULTS: Of 56 heart and 60 lung transplant recipients, 52 (45%) consented, 41 were randomized, and 39 (95%) completed the study with good adherence to randomized diets. After 12 months, changes in many risk factors were seen in the Mediterranean and low-fat-diet groups, respectively, including mean BMI (-0.5 vs. 0.0 kg/m2 ), systolic/diastolic blood pressure +0.5/+0.1 vs -4.4/-3.5 mmHg; fasting glucose -0.26 vs -0.27 mmol/L; total cholesterol -0.56 vs -0.40 mmol/L. Changes in BMI and systolic/diastolic blood pressure in 49 eligible patients who did not take part were +0.7 kg/m2 and +2.5/+1.8 mmHg. DISCUSSION: Dietary interventions in cardiothoracic transplant patients are feasible and potentially beneficial. CONCLUSION: A definitive nutritional intervention study in these high-risk patients is warranted.

A novel hybrid scale for the assessment of cognitive and executive function: The Free-Cog.

BACKGROUND: Scales measuring cognitive and executive functions are integral to the assessment and management of patients with suspected cognitive impairment. Some of the most commonly used cognitive tests are now subject to copyright restrictions. Furthermore, no existing scale assesses both executive and cognitive abilities. AIMS: We aimed to develop and validate a novel hybrid scale for use in clinical practice which integrate measures of cognition and executive abilities ('Free-Cog'). METHODS: The instrument was devised through a national collaboration including health professionals, those with lived experience of dementia and researchers. Following ethics committee approval, the Free-Cog was assessed in 25 real-world clinical settings across England, Wales and Scotland. It was compared to three other cognitive tests routinely administered in clinical practice: the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MOCA), and the Addenbrooke's Cognitive Examination (ACE). RESULTS: The Free-Cog was tested in 960 patients with clinical diagnoses of dementia, Mild Cognitive Impairment (MCI), and normal controls. Similar to the MMSE, MOCA and ACE, it discriminated well between the three groups (p < 0.001). It correlated well with the other instruments. Using a receiver operating characteristic curve analysis, Free-Cog achieved an Area Under Curve of 0.94 for dementia versus controls, 0.80 for MCI versus controls and 0.77 for dementia versus MCI. A version of the tool adapted for telephone consultation, the Tele Free-Cog, also discriminated well between patient groups. CONCLUSIONS: Free-Cog is a non-proprietary, empirically derived, concise assessment. Uniquely, it combines cognitive and executive function questions in the one instrument. It could be used to inform the assessment of people presenting with cognitive impairment and is available to anyone interested in trialling it.

TUBERCULOUS CHOROIDITIS IN PATIENT WITH VOGT-KOYANAGI-HARADA DISEASE.

PURPOSE: To describe a novel case of intraocular tuberculosis (TB) arising in a patient undergoing treatment for Vogt-Koyanagi-Harada disease, and to highlight the use of spectral domain optical coherence tomography for helping confirm the diagnosis and monitor treatment response. METHODS: Case report of a patient with Vogt-Koyanagi-Harada disease on prednisone, with acute clinical changes suspicious for bilateral tuberculous choroiditis. Spectral optical coherence tomography, fundus photography, and B-scan ultrasonography were all used to capture the acute lesions, and to monitor their responses after initiation of anti-TB therapy. RESULTS: New subretinal lesions arose bilaterally, as characterized by spectral domain optical coherence tomography, and appeared to regress after a first round of anti-TB therapy, thereby helping confirm the presumed diagnosis of intraocular TB. A new peripheral choroidal lesion arose shortly after temporary cessation of antimicrobial treatment, and again regressed once four-drug therapy was instituted, with no recurrent lesions thereafter. CONCLUSION: The use of multimodal imaging was instrumental in the management of a rare case of intraocular TB arising in the setting of underlying Vogt-Koyanagi-Harada disease.

Substrate for the Myocardial Inflammation-Heart Failure Hypothesis Identified Using Novel USPIO Methodology.

OBJECTIVES: The purpose of this study was to identify where ultrasmall superparamagnetic particles of iron oxide (USPIO) locate to in myocardium, develop a methodology that differentiates active macrophage uptake of USPIO from passive tissue distribution; and investigate myocardial inflammation in cardiovascular diseases. BACKGROUND: Myocardial inflammation is hypothesized to be a key pathophysiological mechanism of heart failure (HF), but human evidence is limited, partly because evaluation is challenging. USPIO-magnetic resonance imaging (MRI) potentially allows specific identification of myocardial inflammation but it remains unclear what the USPIO-MRI signal represents. METHODS: Histological validation was performed using a murine acute myocardial infarction (MI) model. A multiparametric, multi-time-point MRI methodology was developed, which was applied in patients with acute MI (n = 12), chronic ischemic cardiomyopathy (n = 7), myocarditis (n = 6), dilated cardiomyopathy (n = 5), and chronic sarcoidosis (n = 5). RESULTS: USPIO were identified in myocardial macrophages and myocardial interstitium. R1 time-course reflected passive interstitial distribution whereas multi-time-point R2* was also sensitive to active macrophage uptake. R2*/R1 ratio provided a quantitative measurement of myocardial macrophage infiltration. R2* behavior and R2*/R1 ratio were higher in infarcted (p = 0.001) and remote (p = 0.033) myocardium in acute MI and in chronic ischemic cardiomyopathy (infarct: p = 0.008; remote p = 0.010), and were borderline higher in DCM (p = 0.096), in comparison to healthy controls, but were no different in myocarditis or sarcoidosis. An R2*/R1 threshold of 25 had a sensitivity and specificity of 90% and 83%, respectively, for detecting active USPIO uptake. CONCLUSIONS: USPIO are phagocytized by cardiac macrophages but are also passively present in myocardial interstitium. A multiparametric multi-time-point MRI methodology specifically identifies active myocardial macrophage infiltration. Persistent active macrophage infiltration is present in infarcted and remote myocardium in chronic ischemic cardiomyopathy, providing a substrate for HF.

Influence of chronic kidney disease and haemodialysis on stroke outcome.

INTRODUCTION: Stroke patients with underlying chronic kidney disease (CKD) and those on haemodialysis have complex rehabilitation needs, and their survival and functional outcomes are limited. This study aimed to review post-stroke survival and functional outcomes following rehabilitation in patients with CKD and those on haemodialysis. METHODS: We conducted a retrospective analysis of consecutive stroke patients with underlying CKD (Stages G3b, G4 and G5; n = 30) and those on dialysis at the time of stroke (n = 7), who underwent in-patient rehabilitation between June 2008 and May 2017. The mean duration of follow-up was 56 months. Demographic details, associated comorbidities and laboratory parameters were reviewed. Baseline and follow-up scores of the National Institute of Health Stroke Scale (NIHSS) and Functional Independence Measure (FIM), and dates of death of the patients were analysed. RESULTS: Of the 37 consecutive stroke patients (mean age 64.7 years), 34 had ischaemic stroke and three had haemorrhagic transformation. Significant improvements in NIHSS and FIM scores were observed from the time of admission to after discharge. Older age, longer duration of hospital stay, lower estimated glomerular filtration rate and low haemoglobin levels were all significantly related to mortality. CONCLUSION: Despite significant functional and neurological improvements following rehabilitation, stroke patients with underlying CKD had higher average duration of hospital stay, more recurrent hospitalisations and poorer survival outcomes than those without underlying CKD. This could be attributed to the complications associated with CKD rather than stroke. Multidisciplinary community rehabilitation may be an alternative to reduce recurrent hospitalisations and morbidity in this group of patients.

Increases in arm volume predict lymphoedema and quality of life deficits after axillary surgery: a prospective cohort study.

BACKGROUND: Lymphoedema develops after axillary clearance (ANC) in 25% of patients. This prospective, multi-centre study compared multi-frequency bioimpedance spectroscopy (BIS) with arm volume measurement to: (1) determine which test has better diagnostic accuracy, (2) identify factors predicting development of lymphoedema, and its effect on quality-of-life. METHODS: Participants (N = 1100) underwent measurements pre and post-ANC surgery for breast cancer. Relative arm volume increase (RAVI) of >10% diagnosed lymphoedema. Predictors of lymphoedema were determined using logistic regression. Optimal diagnostic method was assessed using diagnostic accuracy. Quality-of-life was assessed using the FACT B + 4 questionnaire. RESULTS: Lymphoedema was diagnosed in 22.8% women using RAVI > 10%, 45.6% using BIS criteria, while 24.5% underwent compression sleeve application by 24 months. BMI > 30 was an independent factor for both development (p = 0.005) and progression (p = 0.015) of lymphoedema. RAVI at 1 month, BMI > 30 and number of involved nodes contributed to a novel scoring model to predict lymphoedema by 36 months. Larger decreases in QoL scores post-surgery occurred in lymphoedema patients (p < 0.001). Progression to moderate lymphoedema occurred in 15% patients after sleeve application. CONCLUSIONS: RAVI measurement was the best diagnostic tool for lymphoedema. BIS alone is not appropriate for lymphoedema screening or diagnosis. BMI > 30 predicted lymphoedema diagnosis and progression.

The impact of aphasia on Internet and technology use.

Purpose: This study compared Internet use post-stroke in people with aphasia (n = 25) and without aphasia (n = 17). The purpose was to understand how people with aphasia were using the Internet and to investigate the impact of aphasia on their use.Materials and methods: A face-to-face supported questionnaire explored the use of technologies, types of Internet use, traditional and Internet communication, the perception of abilities, and possible barriers to acquiring or improving Internet skills. Descriptive and inferential statistics were used to analyze the data.Results: Internet use ranged from fully independent to by proxy across both groups. Most participants perceived their aphasia as a barrier, but for the majority, it was not the sole reason for failing to acquire or improve skills. Aphasia was related to difficulties with technology-based written communication. Educational attainment was related to participant's feelings about their own skills. Whilst aphasia was important, analysis revealed that age was a stronger predictor of Internet use per se.Conclusions: It is clear that aphasia often negatively affects Internet use and proficiency. However, this research clearly demonstrates that it is important to consider the influence of factors such as age, proxy use, education, and previous technology use and experience.Implications for rehabilitationPost-stroke aphasia contributes negatively to Internet use, particularly in the use of online communication tools such as email and messaging services.Sub-groups of people with aphasia are likely to be more vulnerable to exclusion from the benefits of the Internet; specifically, older people and those with lower levels of educational attainment.It is common for both older adults with and without aphasia to use the Internet via a proxy. Independent use may not always be the desired goal within rehabilitation.People with aphasia may perceive their age and disability as barriers to using the Internet and may lack confidence in their own ability or potential.

The Neurokinin-1 Receptor Antagonist Orvepitant Is a Novel Antitussive Therapy for Chronic Refractory Cough: Results From a Phase 2 Pilot Study (VOLCANO-1).

BACKGROUND: Substance P and the neurokinin-1 (NK-1) receptor are implicated in chronic refractory cough pathophysiology. We assessed the efficacy and safety of orvepitant, a brain-penetrant NK-1 antagonist, in an open-label study in CRC patients with chronic refractory cough. METHODS: Thirteen patients with daytime cough frequency >3 to <250 coughs/h took orvepitant 30 mg once daily for 4 weeks. Objective cough frequency was measured over 24 h at baseline and weeks 1, 4, and 8. The primary end point was change from Baseline in daytime cough frequency at week 4. Secondary end points included cough severity visual analog scale (VAS) score, global ratings of change for cough frequency and severity, and Cough-specific Quality of Life Questionnaire score. RESULTS: All patients completed the study. Mean baseline cough frequency was 71.4/h. A statistically and clinically significant improvement in objective daytime cough frequency was observed at week 4: reduction from baseline of 18.9 (26%) coughs/h (95% CI, 9.6-28.3; P < .001). This effect was apparent at week 1 (reduction from baseline of 27.0 [38%] coughs/h [95% CI, 11.4-42.7; P = .001]) and sustained after drug discontinuation at week 8 (reduction from baseline of 20.4 [29%] coughs/h [95% CI, 3.2-37.5; P = .020]). Statistically significant improvements were seen for severity VAS and quality of life. Orvepitant was safe and well-tolerated. CONCLUSIONS: Orvepitant resulted in a significant and sustained improvement in objective cough frequency, severity VAS, and quality of life; appeared safe; and merits further clinical investigation.

The effectiveness of home versus community-based weight control programmes initiated soon after breast cancer diagnosis: a randomised controlled trial.

BACKGROUND: Breast cancer diagnosis may be a teachable moment for lifestyle behaviour change and to prevent adjuvant therapy associated weight gain. We assessed the acceptability and effectiveness of two weight control programmes initiated soon after breast cancer diagnosis to reduce weight amongst overweight or obese women and prevent gains in normal-weight women. METHODS: Overweight or obese (n = 243) and normal weight (n = 166) women were randomised to a three-month unsupervised home (home), a supervised community weight control programme (community) or to standard written advice (control). Primary end points were change in weight and body fat at 12 months. Secondary end points included change in insulin, cardiovascular risk markers, quality of life and cost-effectiveness of the programmes. RESULTS: Forty-three percent of eligible women were recruited. Both programmes reduced weight and body fat: home vs. control mean (95% CI); weight -2.3 (-3.5, -1.0) kg, body fat -1.6 (-2.6, -0.7) kg, community vs. control; weight -2.4 (-3.6, -1.1) kg, body fat -1.4 (-2.4, -0.5) kg (all p < 0.001). The community group increased physical activity, reduced insulin, cardiovascular disease risk markers, increased QOL and was cost-effective. CONCLUSIONS: The programmes were equally effective for weight control, but the community programme had additional benefits. CLINICAL TRIAL REGISTRATION: ISRCTN68576140.

Communicative Informativeness in Aphasia: Investigating the Relationship Between Linguistic and Perceptual Measures.

Purpose Informativeness refers to how successfully a person is able to convey their intended message. This study explores the relationship between perceptual ratings of informativeness and selected linguistic measures of lexical and structural content. It considers which linguistic measures have ecological validity in terms of what listeners view as important. Method Two complex picture description samples from 20 people with aphasia were analyzed. Linguistic measures included number of correct information units (NCIU), percentage of correct information units, number of propositions (NP), propositional idea density (PID), and mean length of utterance in words (MLU-w). Eleven naïve listeners produced direct magnitude estimation (DME) ratings of informativeness. A correlational design was used to investigate the relationship between mean DME informativeness ratings and each of the linguistic measures. Results The 2 picture description samples elicited similar informativeness ratings. Positive significant correlations were identified between mean DME informativeness ratings and NCIU, percentage of correct information units, NP, and MLU-w; the strength of correlation differed across variables. No significant correlation was found between mean DME informativeness ratings and PID. Significant correlations were also seen between the linguistic variables, particularly between NP and PID as well as NP and MLU-w. Conclusions Overall, the linguistic measures corresponded to rated informativeness, highlighting their ecological validity. The strongest relationship was between NCIU and rated informativeness, emphasizing the importance of complete and accurate production of lexical information, particularly nouns. Less strong, but still significant, relationships were seen with variables looking at the efficiency of information giving and the connection of ideas within sentences. The importance of different types of informative measures is considered in relation to the elicitation stimuli.

Predictors of weight gain in a cohort of premenopausal early breast cancer patients receiving chemotherapy.

AIM: In breast cancer patients, post chemotherapy weight gain is linked with increased risk of cancer recurrence. We prospectively studied a cohort of premenopausal women receiving contemporary chemotherapy following a diagnosis of breast cancer to examine factors predicting weight increase. METHODS: Between May 2005 and January 2008, 523 patients from the Prospective Outcomes in Sporadic versus Hereditary (POSH) breast cancer study entered this sub-study comparing weight prior to chemotherapy and weight and waist/hip measurements 12-months following chemotherapy. RESULTS: Data from 380 patients were available. Mean (standard deviation [SD]) pre-treatment body mass index (BMI) was 26.3 (5.6) kg/m2; 30% women gained > 5% body weight during the study period. Lower BMI at diagnosis predicted greater subsequent post treatment weight gain (4.3% relative weight gain for those in the 1st quartile of BMI compared to 0.8% for those in the 4th quartile; r = -0.22; p < 0.001). No link to chemotherapy regimens, cigarette smoking, previous parity or chemotherapy induced amenorrhoea was noted. A total of 44% of women had central obesity (post-treatment waist measurement of ≥88 cm). CONCLUSIONS: Almost a third of premenopausal patients receiving adjuvant chemotherapy for breast cancer will gain clinically significant weight and over 40% will have central obesity 12-months following diagnosis. A greater weight gain is predicted by lower pretreatment BMI.
