Development and psychometric properties of the Psychological Therapies Outcome Scale - Intellectual Disabilities (PTOS-ID)

BACKGROUND

There are few valid and reliable psychological therapy outcome measures available for use with people with intellectual disabilities (ID). The current study involved the development of a new scale; the Psychological Therapies Outcome Scale - Intellectual Disabilities (PTOS-ID), and the examination of its validity and internal consistency.

METHOD

The PTOS-ID was administered to 175 people who have ID accessing specialist ID services. The construct validity of the scale was investigated through exploratory factor analysis, concurrent validity through comparison with the Brief Symptom Inventory and internal reliability through internal consistency analysis.

RESULTS

Three factors emerged from the principal components analysis with high levels of internal consistency: (1) anger and mood (α = 0.82); (2) positive well-being (α = 0.81); and (3) anxiety (α = 0.76). Factors (1) and (2) were combined to measure psychological distress (α = 0.85), which correlated strongly with the Global Severity Index of the Brief Symptom Inventory (r = 0.85).

CONCLUSIONS

This preliminary study suggests that the PTOS-ID is a psychometrically robust measure of psychological distress and psychological well-being that can be used with people with ID. Further research is required to assess its reliability and ability to detect change.

Associations Between Anesthetic Variables and Functional Outcome in Dogs With Thoracolumbar Intervertebral Disk Extrusion Undergoing Decompressive Hemilaminectomy

Background

Outcome of acute experimental spinal cord injury is strongly associated with tissue perfusion and oxygenation. Cardiopulmonary depression could affect outcome in dogs undergoing general anesthesia for surgical treatment of thoracolumbar intervertebral disk extrusion (IVDE).

Hypothesis/Objectives

To evaluate the effects of general anesthesia on functional outcome in dogs undergoing surgery to treat thoracolumbar IVDE.

Animals

Eighty‐four client‐owned dogs with acute thoracolumbar IVDE treated by decompressive hemilaminectomy.

Methods

Exploratory, retrospective observational study. Medical records were reviewed for clinical presentation and anesthetic monitoring variables, including duration of anesthesia and surgery, hypotension, bradycardia, temperature, and respiratory parameters. Multivariable regression tree analysis was performed to explore associations between anesthetic variables and functional outcome scores after 6 weeks, as well as return to ambulatory status.

Results

Episodes of bradycardia (69%) and hypotension (57%) were frequent. Across all outcome measures, regression tree analysis highlighted functional grade at presentation as the primary determining factor, and among pain perception negative dogs, there was a possible association between increased duration of surgery and poorer outcome. In dogs with intact pain perception, duration of bradycardia, mean body temperature, and mean end‐tidal carbon dioxide were highlighted.

Conclusions and Clinical Importance

Exploratory statistical methods can facilitate hypothesis‐generating studies to inform prospective investigations in veterinary medicine. Although the mechanism is uncertain, increased duration of surgery might be associated with poorer outcome in pain perception negative dogs with thoracolumbar IVDE.

Predictors of developmental surveillance completion at six months of age in south western Sydney

BACKGROUND

While developmental surveillance programs promote early identification of child developmental problems, evidence has indicated suboptimal uptake. This study aimed to identify predictors of developmental surveillance completion at 6 months postpartum.

METHODS

Questionnaires were administered to the parents of 510 infants who were born in south western Sydney, Australia over a 22-month period. Attendance for developmental screening and completion of the Parents' Evaluation of Developmental Status (PEDS) at 6 months postpartum were modelled separately using multivariable logistic regression.

RESULTS

Developmental surveillance attendance was predicted by higher levels of maternal education, annual income and being informed about checks. PEDS completion at 6 months of age was predicted by higher income and being informed, as well as being married, employed, speaking English at home, full-term birth and the professional status of the practitioner completing the check.

CONCLUSIONS

Barriers to developmental surveillance included low socioeconomic status, linguistic diversity and possible gaps in parental knowledge and professional education. Developmental surveillance rates may be increased by the addition of targeted parental and professional support within current universal frameworks.

Abstract P2-03-02: Differential mutation pattern between neoadjuvant and metastatic settings in breast cancer patients

Background: Dysregulated signaling pathways occur in human cancers including breast cancer, making it a rational target for novel genome guided combinatorial personalized therapies. The aim of the present study was to investigate the different genetic mutation pattern between neoadjuvant and metastatic settings in breast cancer patients to guide research and clinical treatment.

Material and Methods: 150 breast cancer patients were involved in this study. 38 patients were receiving neoadjuvant treatment and 112 patients were in the metastatic setting. Tumor specimens obtained from the 150 patients were subjected to genetic mutation testing by FoundationOne. Genetic alterations detected by FoundationOne test were collected and analyzed.

Results: 96 and 149 different genes where reported by FoundationOne in neoadjuvant and metastatic setting respectively. The average number of non-synonymous mutation was five per case in the neoadjuvant setting and six per case in the metastatic setting. TP53 (58%), MYC (32%), PIK3CA (29%), PTEN (16%), CDH1 (13%), CCND1 (11%), EMSY (11%), LYN (11%) and ZNF703 (11%) were the most seen mutations in neoadjuvant setting. TP53 (40%), PIK3CA (39%), MYC (22%), CCND1 (21%), FGF19 (21%), FGF4 (21%), CDH1 (20%), FGF3 (19%), ERBB2 (17%), ESR1 (14%), FGFR1 (14%), ZNF703 (14%), GATA3 (13%), MYST3 (11%), PTEN (11%), EMSY (10%), NF1 (10%) and ZNF217 (10%) were the most seen mutations in metastatic setting. ESR1 and GATA3, which are seen in 14% and 13% of metastatic breast cancer patients, were not reported in neoadjuvant breast patients. Moreover, among the 16 metastatic breast cancer patients who has ESR1 mutation, 9 (56%) of them presented with PIK3CA or other genetic mutations which are directly involved in the phosphoinositide 3-kinase (PI3K)/AKT pathway.

Conclusion: A significantly more mutation in Receptor Tyrosine Kinases (RTKs)/ Growth Factor Signaling ( especially ERBB and FGFR pathways) was reported in the metastatic setting compare to the neoadjuvant setting, suggesting a critical role of the RTKs in metastatic breast cancer patients. The coexisting of ESR1 and PI3K/AKT pathway alteration and the absence of ESR1 in neoadjuvant setting also suggested that in early stage breast cancer patients who have a PI3K pathway alterations; there is a higher chance to develop ESR1 mutation with disease progression.

Using quality improvement methods to increase use of pain prevention strategies for childhood vaccination

AIM

To increase evidence-based pain prevention strategy use during routine vaccinations in a pediatric primary care clinic using quality improvement methodology.

METHODS

Specific intervention strategies (i.e., comfort positioning, nonnutritive sucking and sucrose analgesia, distraction) were identified, selected and introduced in three waves, using a Plan-Do-Study-Act framework. System-wide change was measured from baseline to post-intervention by: (1) percent of vaccination visits during which an evidence-based pain prevention strategy was reported as being used; and (2) caregiver satisfaction ratings following the visit. Additionally, self-reported staff and caregiver attitudes and beliefs about pain prevention were measured at baseline and 1-year post-intervention to assess for possible long-term cultural shifts.

RESULTS

Significant improvements were noted post-intervention. Use of at least one pain prevention strategy was documented at 99% of patient visits and 94% of caregivers were satisfied or very satisfied with the pain prevention care received. Parents/caregivers reported greater satisfaction with the specific pain prevention strategy used [t(143) = 2.50, P≤ 0.05], as well as greater agreement that the pain prevention strategies used helped their children’s pain [t(180) = 2.17, P≤ 0.05] and that they would be willing to use the same strategy again in the future [t(179) = 3.26, P≤ 0.001] as compared to baseline. Staff and caregivers also demonstrated a shift in attitudes from baseline to 1-year post-intervention. Specifically, staff reported greater agreement that the pain felt from vaccinations can result in harmful effects [2.47 vs 3.10; t(70) = -2.11, P≤ 0.05], less agreement that pain from vaccinations is “just part of the process” [3.94 vs 3.23; t(70) = 2.61, P≤ 0.05], and less agreement that parents expect their children to experience pain during vaccinations [4.81 vs 4.38; t(69) = 2.24, P≤ 0.05]. Parents/caregivers reported more favorable attitudes about pain prevention strategies for vaccinations across a variety of areas, including safety, cost, time, and effectiveness, as well as less concern about the pain their children experience with vaccination [4.08 vs 3.26; t(557) = 6.38, P≤ 0.001], less need for additional pain prevention strategies [3.33 vs 2.81; t(476) = 4.51, P≤ 0.001], and greater agreement that their doctors’ office currently offers pain prevention for vaccinations [3.40 vs 3.75; t(433) = -2.39, P≤ 0.05].

CONCLUSION

Quality improvement methodology can be used to help close the gap in implementing pain prevention strategies during routine vaccination procedures for children.

Disability, depression and suicide ideation in people with multiple sclerosis

INTRODUCTION

Depressive symptoms occur frequently in people with Multiple Sclerosis (MS) and rates of suicide ideation are higher than the general population. There is evidence for a direct association between disability and depression, disability and suicide ideation, and depression and suicide ideation in MS. However, the relationship between all three, i.e. the mediating role of depression between disability and suicidal ideation, has not been investigated. Exploring this relationship could highlight risk factors, alerting clinicians to the need for timely intervention.

METHOD

Seventy five people with progressive MS attending two out-patient clinics took part in this cross-sectional study. Participants completed the Beck Suicide Scale, Beck Depression Inventory, Multiple Sclerosis Impact Scale and Guy's Neurological Disability Scale.

RESULTS

Depressive symptoms mediated the relationship between perceived and actual disability and suicide ideation. Different types of disability were associated with suicidality, including: 'tremors' and 'taking longer to do things'. A small sub-group of participants were identified who reported suicide ideation in the presence of only mild levels of depression.

LIMITATIONS

There may be a sample bias in this study as all participants were attending out-patient clinics and receiving support which may not be available to everyone with MS.

CONCLUSION

It is important for clinicians to screen regularly for both depression and suicide ideation, to be alert to specific types of disability for which a higher level of suicide ideation might be present and to consider the possibility of suicidal thoughts being present in people who show minimal or no depressive symptoms.

Effect of Cranberry Extract on the Frequency of Bacteriuria in Dogs with Acute Thoracolumbar Disk Herniation: A Randomized Controlled Clinical Trial

Background

Dogs with spinal cord injury are at increased risk of developing bacteriuria due to increased residual urine volume. Cranberry extract inhibits binding of E. coli to uroepithelial cells, potentially reducing risk of bacteriuria.

Hypothesis

Cranberry extract reduces risk of bacteriuria in dogs after acute TL‐IVDH.

Animals

Client‐owned dogs with acute onset TL‐IVDH causing nonambulatory status.

Methods

Randomized, placebo‐controlled, blinded, prospective clinical trial. Dogs with acute TL‐IVDH were recruited 48 hours postoperatively and randomized to receive cranberry extract or placebo in a masked fashion. Urine cultures and neurological examinations were performed 2, 4, and 6 weeks postoperatively. The number of dogs with bacteriuria (all bacterial species) and bacteriuria (E. coli) were primary and secondary outcome measures and were evaluated using chi‐squared test. Urine antiadhesion activity (AAA) was measured in a subset (N = 47) and examined in a secondary analysis evaluating additional risk factors for bacteriuria.

Results

Bacteriuria was detected 17 times in 94 dogs (6 placebo, 11 cranberry, P = .12). There were 7 E. coli. positive cultures (1 placebo, 6 cranberry, P = .09). Dogs in both groups had positive urine AAA (14/21: placebo, 16/26: cranberry), and dogs with urine AAA had significantly fewer E. coli positive cultures (n = 1) than dogs without it (n = 4) (P = .047).

Conclusions and Clinical Importance

This clinical trial did not show a benefit of oral cranberry extract but had low power. Cranberry extract supplementation did not impact urine AAA, but a possible association between urine AAA and lower risk of E. coli bacteriuria was identified. Other doses could be investigated.

REEXAMINING THE ASSOCIATION OF MATERNAL AGE AND MARITAL STATUS AT FIRST BIRTH WITH YOUTH EDUCATIONAL ATTAINMENT

Using data from the linked Children and Young Adult sample (N = 2,865) of the NLSY79, we reexamined the association of maternal age and marital status at birth with youth high school completion, assessing multiple age categories and race/ethnic variations. Youth born to older teen mothers were no more likely to graduate from high school than those born to the youngest teen mothers. Although delaying childbirth to young adulthood (age 20-24) was associated with greater odds of children's high school completion compared to the earliest teen births, those born to young adult mothers were disadvantaged compared to those born to mothers age 25 or older. Being born to an unmarried mother was associated with lower odds of high school completion but this did not fully explain the estimated effect of maternal age at birth. We found no evidence that maternal age at birth more strongly predicted high school graduation for White compared to Latino or Black youth.

"What about diet?" A qualitative study of cancer survivors' views on diet and cancer and their sources of information

Given the abundance of misreporting about diet and cancer in the media and online, cancer survivors are at risk of misinformation. The aim of this study was to explore cancer survivors' beliefs about diet quality and cancer, the impact on their behaviour and sources of information. Semi-structured interviews were conducted with adult cancer survivors in the United Kingdom who had been diagnosed with any cancer in adulthood and were not currently receiving treatment (n = 19). Interviews were analysed using Thematic Analysis. Emergent themes highlighted that participants were aware of diet affecting risk for the development of cancer, but were less clear about its role in recurrence. Nonetheless, their cancer diagnosis appeared to be a prompt for dietary change; predominantly to promote general health. Changes were generally consistent with healthy eating recommendations, although dietary supplements and other non-evidence-based actions were mentioned. Participants reported that they had not generally received professional advice about diet and were keen to know more, but were often unsure about information from other sources. The views of our participants suggest cancer survivors would welcome guidance from health professionals. Advice that provides clear recommendations, and which emphasises the benefits of healthy eating for overall well-being, may be particularly well-received.

Copper-Associated Hepatopathy in a Mexican Fruit Bat (Artibeus Jamaicensis) and Establishment of a Reference Range for Hepatic Copper in Bats

Copper toxicity has been described in numerous domestic species. The characteristic lesions include hemoglobinuric nephrosis and piecemeal hepatic necrosis with bile ductular hyperplasia and portal fibrosis. Certain species, such as sheep, are prone to toxicity when exposed to copper in feed, whereas an inherent genetic defect of copper storage is present in some breeds of dogs (Bedlington Terriers, West Highland White Terriers, Doberman Pinschers). In nondomestic species, reference ranges have not been established for copper in internal organs, so the establishment of copper toxicity as a diagnosis is difficult. A case of copper toxicity in a captive Mexican fruit bat is presented. Hepatic copper levels in 16 additional bats, of at least 3 different species, were measured. To the authors' knowledge, this is the first reported case of copper toxicity in a chiropteran.

First Measurement of Electron Neutrino Appearance in NOvA

We report results from the first search for ν_{μ}→ν_{e} transitions by the NOvA experiment. In an exposure equivalent to 2.74×10^{20} protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δ_{CP}<0.5π in the inverted mass hierarchy at the 90% C.L.

Recovery of stepping and coordination in dogs following acute thoracolumbar intervertebral disc herniations

Prospective data on the recovery of coordination in dogs suffering acute thoracolumbar intervertebral disc herniations (TL-IVDH) are limited. The purpose of this study was to use treadmill based and open field scores (OFS) to quantify recovery of stepping ability and forelimb, hindlimb coordination in the 6 weeks following surgical decompression of dogs with TL-IVDH. Sixty-three dogs were grouped at presentation as grades 3 (non-ambulatory paraparetic), 4 (paraplegic) or 5 (paraplegic without pain sensation) and were evaluated 2, 4, and 6 weeks post-operatively. Stepping scores and Regularity Index (RI), a measure of coordination, were calculated from treadmill walking, and an OFS incorporating supported and unsupported walking was assigned. Outcomes for the three measures were compared between groups and correlation between scoring methods was assessed. Grade 3 and 4 dogs recovered ambulation by 2 weeks, reaching median stepping scores of 96 and 90% by 6 weeks, respectively. Recovery of coordination differed between groups 3 and 4 with median RI scores of 93.9% and 63%, respectively, by 6 weeks. Eight grade 5 dogs failed to recover independent ambulation by 6 weeks. Nine dogs recovered with scores that were significantly worse than the grade 3 and 4 dogs at 6 weeks for stepping score (P < 0.001) and RI (P < 0.001). OFS correlated closely with stepping and RI scores and each group was significantly different using this ordinal scale. In conclusion, recovery of coordination was incomplete in dogs that showed good recovery of stepping. The data generated could be used for clinical trial design.

Non-biological determinants of paediatric bladder bowel dysfunction: A pilot study

OBJECTIVES

Children with bladder and bowel dysfunction (BBD) constitute a significant proportion of referrals at paediatric urology clinics worldwide, presenting with a wide range of symptom severity that may significantly affect quality of life. Non-biological factors may play a key role in triggering BBD severity, but these underpinning causes of BBD during childhood are still unknown. The aim of this study was to identify the effects of personal, family related and environmental variables on the severity of BBD symptoms in school-aged children.

STUDY DESIGN

A pilot, prospective, observational study was conducted on 53 children diagnosed with BBD, and their legal guardian(s), on their first referred visit to a paediatric BBD clinic led by nurse practitioners. Upon receiving consent, patients and their legal guardian(s) completed three study questionnaires, with the guidance of research coordinators. The first questionnaire was the Dysfunctional Voiding Scoring System (DVSS); the second, a three-part questionnaire used to collect demographic information and data on the patient, their family and environmental characteristics; and the third gathered a detailed history of the child's lifestyle regimen, focusing on their bowel and bladder function.

RESULTS

Most of the children were female (66%), with an average age of 8.35 years. Most children attended public schools (74%) and none reported failing a grade. The mean parental age was 41.4 years (SD = 4.9 years), 62% of the families had two children and 53% were Caucasian. The mean DVSS score for this sample was 9.9 (SD = 4.2, range 2-21). Daycare attendance, school problems and unplanned pregnancy showed statistically significant influences on the severity of BBD and were associated with higher DVSS scores according to the Table below.

CONCLUSIONS

Children with BBD attending urology outpatient clinics as new referrals had more severe symptoms when they were born from an unplanned pregnancy, attended daycare and/or had school problems. These findings suggest that interventions aimed at decreasing BBD severity, or preventing its onset in school-aged children, should focus on the environment surrounding them, specifically on the interaction between personal, familial and environmental factors. These factors seem to have an important effect on paediatric continence, as children grow and develop under numerous societal influences and social interactions.

Pulmonary Veno-Occlusive Disease

Pulmonary hypertension is a well-known though poorly characterized disease in veterinary medicine. In humans, pulmonary veno-occlusive disease (PVOD) is a rare cause of severe pulmonary hypertension with a mean survival time of 2 years without lung transplantation. Eleven adult dogs (5 males, 6 females; median age 10.5 years, representing various breeds) were examined following the development of severe respiratory signs. Lungs of affected animals were evaluated morphologically and with immunohistochemistry for alpha smooth muscle actin, desmin, CD31, CD3, CD20, and CD204. All dogs had pulmonary lesions consistent with PVOD, consisting of occlusive remodeling of small- to medium-sized pulmonary veins, foci of pulmonary capillary hemangiomatosis (PCH), and accumulation of hemosiderophages; 6 of 11 dogs had substantial pulmonary arterial medial and intimal thickening. Ultrastructural examination and immunohistochemistry showed that smooth muscle cells contributed to the venous occlusion. Increased expression of CD31 was evident in regions of PCH indicating increased numbers of endothelial cells in these foci. Spindle cells strongly expressing alpha smooth muscle actin and desmin co-localized with foci of PCH; similar cells were present but less intensely labeled elsewhere in non-PCH alveoli. B cells and macrophages, detected by immunohistochemistry, were not co-localized with the venous lesions of canine PVOD; small numbers of CD3-positive T cells were occasionally in and around the wall of remodeled veins. These findings indicate a condition in dogs with clinically severe respiratory disease and pathologic features resembling human PVOD, including foci of pulmonary venous remodeling and PCH.

Abstract P4-08-04: Navigating genomic landscape to find a PI3K-signaling algorithm for a rational combinatin in precision medicine

Background: Treatment of BC is conventionally based on the presence/absence of ER/PR or HER2 status of the primary tumor. We have enriched this approach by including major genetic and proteomic changes in tumors of individual patients in order to develop a better treatment-rationale based on an alteration driven signaling algorithm. Methods: Genomic and proteomic data from 75 BC patients seen in our center were retrospectively analyzed. Patients were re-biopsied after consultation and samples were characterized (IHC for ER, PR, and HER2; FFPE samples for genomic [Foundation Medicine] and proteomic analyses [Theranostics]). In vivo studies were conducted using xenograft models. Results: Although alterations of PIK3CA, PIK3R1, AKT, PTEN, MDM2, MDM4, TSC1, mTOR and RICTOR are most frequently observed in our patients, there is a distinct pattern of alteration(s) of the PI3K pathway genes in different subtypes of BC. A total of 76 genes were altered in 48 ER+BC patients. In 79% of ER+BC patients the above mentioned PI3K pathway genes were altered. Analyzing the set of alterations of genes in individual patients, we observed that within these 48 patients 25% exhibited alterations in more than one node of the pathway; the most common combination (alterations) being the amplification/mutation of PIK3CA with the amplification of MDM2/4 genes. The percentage of patients belonging to HER2+ & TNBC exhibiting similar alterations in the PI3K pathway genes were significantly lower (∼40%). Our previous in vivo studies demonstrated that GDC-0980 and BEZ235 enhanced the antitumor activity of ABT888 plus carboplatin in TNBC or trastuzumab in HER2+ BC respectively and blocked the growth of established xenograft tumors by 80% to 90% with a concomitant decrease in tumor Ki67, pS6RP and CD31. Mechanistically the action of the PI3K-mTOR pathway targeted drug(s) was tested using cell line based models of BC subtypes pertaining to their respective genomic alterations. A combination of a pan-PI3K pathway inhibitor, GDC-0941 or isoform-specific inhibitors along with AI, trastuzumab, or HRD inhibitors (PARP) blocked proliferative signals and enhanced apoptosis (cleaved caspase3) in ER+/PIK3CA mutated, HER2+/PIK3CA mutated or PTEN-null TNBC cells respectively as demonstrated by WB, flow cytometry, cell proliferation, viability and cytotoxicity assays. A recent study demonstrated that exposure to chemotherapy induced a phenotypic shift or cell state transition towards a transient CD44Hi/CD24Hi chemotherapy-tolerant state, leading to the activation of downstream non-receptor tyrosine kinase signaling towards an emerging adaptive resistance (Goldman et al., Nature Comm. 2015). Hence drug combination(s) are being tested for their effect on CD44/CD24 expression levels, results of which will be presented in the meeting. Conclusion: Plotting the genetic alterations from the patient on the signaling landscape will be useful in cracking the code leading to improved treatment options. Patient specific in-depth plotting of genetic alterations of the PI3K-mTOR pathway and the relevance of these alterations in the context of (1) mechanisms of PI3K-mTOR pathway targeted drugs and (2) cell signaling are critical in determining choice of drugs in BC subtypes.

Health behaviours and fear of cancer recurrence in 10 969 colorectal cancer (CRC) patients

Background

This study aimed to examine whether fear of cancer recurrence (FCR) was related to two important health behaviours (physical activity and smoking) in a large sample of colorectal cancer patients.

Methods

Ten thousand nine hundred sixty nine patients, diagnosed in 2010–11, and in remission in 2013, completed the ‘Living with and Beyond Colorectal Cancer’ survey. The survey included purpose‐designed questions on fear of recurrence (‘I have fear about my cancer coming back’), demographics, treatment and health variables. Physical activity (PA) was recorded as number of days per week doing at least 30 min of brisk activity, and smoking status was reported.

Results

Fifty per cent of respondents reported fear of their cancer returning. More women than men ((Odds Ratio; (OR) 1.58; 95% confidence interval (CI) 1.46, 1.71)) more younger than older patients (OR 2.53; CI 2.33, 2.74) and slightly more patients from deprived areas (OR 1.14, 1.05, 1.23) reported FCR. Independently of demographics and treatment, compared with those meeting the PA guidelines, those who were doing only ‘some’ (OR 1.22; CI 1.11, 1.35) or ‘no’ PA (OR 1.28; CI 1.15, 1.42) reported higher FCR. Compared with non‐smokers, more current smokers reported fear (OR 1.34, CI 1.10, 1.58) and slightly more ex‐smokers (OR 1.11; CI 1.04, 1.21).

Conclusions

This cross‐sectional study provided novel data showing that colorectal cancer survivors with poorer health behaviours (those with lower activity levels and those who smoked) were more likely to experience FCR. Future research should replicate findings using detailed measures of fear, objective measures of health behaviours and identify directions of associations. © 2016 The Authors.

Ultrasound and magnetic resonance imaging assessment of joint disease in symptomatic patients with cystic fibrosis arthropathy

OBJECTIVES

Cystic fibrosis arthropathy (CFA) is a term commonly used for joint pain with and without swelling seen in some patients with CF. Early studies into CFA focused on the presence of rheumatoid factor and immunological changes on synovial biopsy, with parallels drawn between respiratory and joint activity. Identification of anti-cyclic citrullinated peptide antibodies (anti-CCP) as a marker of rheumatoid arthritis (RA), along with increased access to sensitive imaging techniques including ultrasound (US) and magnetic resonance imaging (MRI), offer great potential to investigate and more accurately understand the type(s) of inflammatory arthritis that may underlie CFA. The aim of this study was to phenotype an active CFA cohort using serology and imaging, as a basis for further work in this understudied area.

METHODS

This was a prospective observational cohort study of symptomatic CFA patients presenting with joint pain. Participants underwent serological testing, clinical and US joint and entheseal assessment, as well as MRI of the most symptomatic joint/joint area.

RESULTS

Ten symptomatic patients were studied with 9/10 having positive clinical findings. Inflammatory changes on US were seen in 8/10 cases. Five patients had positive findings on MRI (3 of whom had received IV gadolinium contrast). This included patients with significant erosive changes. One patient was anti-CCP positive suggestive of RA, and two were anti-nuclear antibody positive.

CONCLUSION

Imaging, and to a lesser extent serology, identified inflammatory joint pathology in a proportion of cases, providing important data to explore in a large CFA cohort examining the clinical and imaging phenotype of this group.

Voriconazole Exposure and Risk of Cutaneous Squamous Cell Carcinoma, Aspergillus Colonization, Invasive Aspergillosis and Death in Lung Transplant Recipients

Voriconazole is a triazole antifungal used to prevent and treat invasive fungal infections after lung transplantation, but it has been associated with an increased risk of developing cutaneous squamous cell carcinoma (SCC). Despite widespread use, there are no clear guidelines for optimal prophylactic regimens that balance the competing risks and benefits. We conducted a retrospective cohort study of all lung transplant recipients at the University of California, San Francisco, who were transplanted between October 1991 and December 2012 (n = 455) to investigate whether voriconazole exposure affected development of SCC, Aspergillus colonization, invasive aspergillosis and all-cause mortality. Voriconazole exposure was associated with a 73% increased risk of developing SCC (hazard ratio [HR] 1.73; 95% confidence interval [CI]: 1.04-2.88; p = 0.03), with each additional 30-day exposure at the standard dose increasing the risk by 3.0% (HR 1.03; 95% CI: 1.02-1.04; p < 0.001). Voriconazole exposure reduced risk of Aspergillus colonization by 50% (HR 0.50; 95% CI: 0.34-0.72; p < 0.001), but we were underpowered to detect risk reduction for invasive aspergillosis. Voriconazole exposure significantly reduced all-cause mortality among subjects who developed Aspergillus colonization (HR 0.34; 95% CI: 0.13-0.91; p = 0.03) but had no significant impact on those without colonization. Physicians should consider patient-specific factors that modify the potential risks and benefits of voriconazole for the care of lung transplant recipients.

First-birth Timing, Marital History, and Women's Health at Midlife

Despite evidence that first-birth timing influences women's health, the role of marital status in shaping this association has received scant attention. Using multivariate propensity score matching, we analyze data from the National Longitudinal Survey of Youth 1979 to estimate the effect of having a first birth in adolescence (prior to age 20), young adulthood (ages 20-24), or later ages (ages 25-35) on women's midlife self-assessed health. Findings suggest that adolescent childbearing is associated with worse midlife health compared to later births for black women but not for white women. Yet, we find no evidence of health advantages of delaying first births from adolescence to young adulthood for either group. Births in young adulthood are linked to worse health than later births among both black and white women. Our results also indicate that marriage following a nonmarital adolescent or young adult first birth is associated with modestly worse self-assessed health compared to remaining unmarried.

Childhood Adversity and Men's Relationships in Adulthood: Life Course Processes and Racial Disadvantage

OBJECTIVES

Prior U.S. population studies have found that childhood adversity influences the quality of relationships in adulthood, with emerging research suggesting that this association might be especially strong for black men. We theorize psychosocial and behavioral coping responses to early life adversity and how these responses may link early life adversity to strain in men's relationships with their indeterminate partners and children across the life course, with attention to possible racial variation in these experiences and implications for later life well-being.

METHOD

We analyze in-depth interviews with 15 black men and 15 white men. We use qualitative analysis techniques to connect childhood experiences to psychosocial processes in childhood and behavioral coping strategies associated with relationship experiences throughout adulthood.

RESULTS

Black men describe much stronger and more persistent childhood adversity than do white men. Findings further suggest that childhood adversity contributes to psychosocial processes (e.g., diminished sense of mastery) that may lead to ways of coping with adversity (e.g., self-medication) that are likely to contribute to relationship difficulties throughout the life span.

DISCUSSION

A life course perspective directs attention to the early life origins of cumulative patterns of social disadvantage, patterns that extend to later life. Our findings suggest psychosocial and behavioral pathways through which early life adversity may constrain and strain men's relationships, possibly contributing to racial inequality in family relationships across the life span.

Tertiary paediatric hospital admissions in children and young people with cerebral palsy

BACKGROUND

Many previous studies that have investigated hospital admissions in children and young people with cerebral palsy lack information on cerebral palsy severity and complexity. Consequently, little is known about factors associated with the frequency and type of hospital admissions in this population. This study used hospital admission data available for all children and young people known to a population-based cerebral palsy register to describe the patterns of use of tertiary paediatric hospital services over a 5-year period.

METHODS

This was a retrospective cohort analysis of routinely collected admission data from the two tertiary paediatric hospitals in the Australian state of Victoria. Data on admissions of individuals born between 1993 and 2008 registered on the Victorian Cerebral Palsy Register were analysed (n = 2183).

RESULTS

Between 2008 and 2012, 53% of the cohort (n = 1160) had at least one same-day admission, and 46% (n = 996) had one or more multi-day admissions. Those with a moderate to severe motor impairment and those with a co-diagnosis of epilepsy had more admissions, and for multi-day admissions, longer lengths of stay, P < 0.05. Across all severity levels, respiratory and musculoskeletal diseases were the most frequently reported reasons for medical and surgical admissions, respectively. All-cause readmission rates for urgent multi-day stays within 7, 30 and 365 days of an index admission were 10%, 23% and 63%, respectively.

CONCLUSIONS

The reasons for hospital admissions reported here reflect the range of comorbidities experienced by children and young people with cerebral palsy. This study highlights priority areas for prevention, early diagnosis and medical management in this group. Improved primary and secondary prevention measures may decrease non-elective hospital admissions and readmissions in this group and reduce paediatric inpatient resource use and healthcare expenditure attributable to cerebral palsy.

Improving paediatric outreach services for urban Aboriginal children through partnerships: views of community-based service providers

BACKGROUND

In Australia, Aboriginal children experience significantly poorer health outcomes compared with non-Aboriginal children. Health policies aimed at improving Aboriginal health outcomes include interventions in the early childhood period. There is a need for government health services to work in partnership with Aboriginal people and other services to achieve the highest level of health possible for Aboriginal children, who often require a range of services to meet complex needs.

AIM

This paper describes the views of service providers on how paediatric outreach services work in partnership with other services, Aboriginal families and the community and how those partnerships could be improved to maximize health outcomes for children.

METHODS

In-depth, semi-structured interviews and focus groups were conducted with managers and service providers over a 6-week period in 2010. The views and suggestions of participants were documented and a thematic analysis was undertaken.

RESULTS AND DISCUSSION

Analysis of two focus groups with seven service providers and five individual interviews with service managers resulted in the identification of four themes: (i) using informal and formal ways of working; (ii) cultivating effective relationships; (iii) demonstrating cultural sensitivity; and (iv) forging strong leadership. Use of formal and informal approaches facilitated effective relationships between service providers and Aboriginal families and communities. Partnerships with the community were founded on a culturally appropriate model of care that recognized a holistic approach to health and wellness. Leadership emerged as an essential component of effective partnerships, cultivating the ethos of the workplace and creating an environment where collaboration is supported.

CONCLUSION

Culturally appropriate child health services, which utilize effective relationships and employ a range of informal and formal collaboration with other services and community members, are well positioned to implement health policy and improve access to services for Aboriginal children with better health outcomes as a result.

Nonmarital Fertility, Union History, and Women's Wealth

We use more than 20 years of data from the National Longitudinal Survey of Youth 1979 to examine wealth trajectories among mothers following a nonmarital first birth. We compare wealth according to union type and union stability, and we distinguish partners by biological parentage of the firstborn child. Net of controls for education, race/ethnicity, and family background, single mothers who enter into stable marriages with either a biological father or stepfather experience significant wealth advantages over time (more than $2,500 per year) relative to those who marry and divorce, cohabit, or remain unpartnered. Sensitivity analyses adjusting for unequal selection into marriage support these findings and demonstrate that race (but not ethnicity) and age at first birth structure mothers' access to later marriage. We conclude that not all single mothers have equal access to marriage; however, marriage, union stability, and paternity have distinct roles for wealth accumulation following a nonmarital birth.

Fungal contamination of nebuliser devices used by people with cystic fibrosis

BACKGROUND

Poor nebuliser hygiene can result in bacterial contamination and risk of infections. The aim of this study was to assess the prevalence of fungal contamination of nebulisers used by adults with cystic fibrosis.

METHODS

A total of 170 nebulisers from 149 subjects were screened by wetting a sterile cotton swab with sterile water and swabbing each drug chamber. The swab was then plated out on Sabouraud and on Scel+agar and incubated at 27 °C for up to 2 weeks.

RESULTS

Fungal cultures were positive in 86 (57.7%) patient's devices. In 28/149 (18.8%), 39/149 (26.2%), 47/149 (31.5%) and 20/149 (13.4%) of subjects Aspergillus species, yeasts, moulds and both yeasts and moulds were isolated respectively. There was no difference in contamination rates between different devices.

CONCLUSION

Nebuliser devices are frequently contaminated by moulds and yeasts and emphasis should be placed on ensuring adequate nebuliser hygiene.
