Abstract
BACKGROUND Fear of disease progression (FOP) is a rational concern for women with Ovarian Cancer (OC) and depression is also common. To date there have been no randomized trials assessing the impact of psychological intervention on depression and FOP in this patient group. PATIENTS AND METHODS Patients with primary or recurrent OC who had recently completed chemotherapy were eligible if they scored between 5 and 19 on the PHQ-9 depression and were randomized 1:1 to Intervention (3 standardized CBT-based sessions in the 6-12 weeks post-chemotherapy) or Control (standard of care). PHQ-9, FOP-Q-SF, EORTC QLQ C30 and OV28 questionnaires were then completed every 3 months for up to 2 years. The primary endpoint was change in PHQ-9 at 3 months. Secondary endpoints were change in other scores at 3 months and all scores at later timepoints. RESULTS 182 patients registered; 107 were randomized; 54 to Intervention and 53 to Control; mean age 59 years; 75 (70%) had completed chemotherapy for primary and 32 (30%) for relapsed OC and 67 patients completed both baseline and 3-month questionnaires. Improvement in PHQ-9 was observed for patients in both study arms at three months compared to baseline but there was no significant difference in change between Intervention and Control. A significant improvement on FOP-Q-SF scores was seen in the Intervention arm, whereas for those in the Control arm FOP-Q-SF scores deteriorated at 3 months (intervention effect = -4.4 (-7.57, -1.22), p-value = 0.008). CONCLUSIONS CBT-based psychological support provided after chemotherapy did not significantly alter the spontaneously improving trajectory of depression scores at three months but caused a significant improvement in FOP. Our findings call for the routine implementation of FOP support for ovarian cancer patients.

Abstract
Introduction With advancing age, frailty, multi-morbidity and need for care, elderly patients are some of the most vulnerable to Covid-19 disease. In NHS Tayside, a dedicated Covid-19 Medicine for the Elderly (MFE) Team was formed to care for patients identified as frail and likely to benefit from comprehensive geriatric assessment. Methods All Covid-19 patients meeting frailty criteria1, cared for by the Covid-19 MFE Team were identified. Data on outcomes and clinical characteristics for all (140) patients admitted during the first pandemic wave (March–July 2020) was collected using electronic patient records and analysed. Results Patients were predominantly male (58.6%). Ages ranged from 65–99 years, with 43.6% aged ≥85 years. 82.1% had one or more of cough, fever and anosmia on admission fitting Covid-19 case definition 2. Lymphopenia was present in 92.1%. Of note, 26.5% of patients had a normal or unchanged chest x-ray report, with only 10.2% showing bilateral peripheral infiltrates. 28-day mortality was 37.1% with Covid-19 Disease listed as primary cause of death in 90.4%. Conclusion(s) Entering further “waves” of infection, it is vital that we understand the clinical presentation and course of Covid-19 disease in elderly patients. Our data highlights that any Covid-19 symptom, even in isolation, should raise suspicion of disease. Chest x-rays should not be used alone as a diagnostic tool. The presence of lymphopenia should raise suspicion of Covid-19 infection. In developing an understanding of how elderly patients with Covid-19 present, we can ensure early identification and initiation of appropriate infection control measures. References 1.

Abstract
Cutaneous photodamage is incited via exposure of ultraviolet-B (UV-B) radiation to skin, characterized by the manifestation of oxidative stress, inflammation, collagen degradation and apoptosis which translates to external aging signs such as wrinkle formation and leathery skin appearance. Meanwhile, it increases cellular susceptibility to photocarcinogenesis. Several studies have accumulated evidence regarding the usage of natural agents in reversing the clinical signs of photoaging as well as preventing photo-toxicity at molecular level. In this study, we have explored the therapeutic potential of natural agent Trigonelline (TG) against UV-B radiation mediated skin photodamage. Various parameters modulated by the exposure of UV-B radiation were investigated in human skin cells and chronic photodamage mice model (Balb/c). We found that TG alleviates UV-B radiation induced photodamage in human skin cells and Balb/c skin mice. TG treatment in UV-B irradiated skin cells abates UV-B radiation mediated phototoxicity, oxidative stress, inflammation and apoptosis. At molecular level, we observed TG treatment significantly prevents the reactive oxygen species (ROS) generation and lipid peroxidation, restores collagen synthesis and matrix metalloproteinase (MMPs) levels. The in vitro findings were replicated in the in vivo model. We found that the TG acts potentially via modulation of ROS-MAPKs-NF-κB axis. Collectively, we propose that TG acts antagonistically against UV-B mediated skin damage and has strong potential to be developed as a therapeutic and cosmetical agent against photodamage disorders.

Abstract
Corticobasal degeneration typically progresses gradually over 5–7 years from onset till death. Fulminant corticobasal degeneration cases with a rapidly progressive course were rarely reported (RP-CBD). This study aimed to investigate their neuropathological characteristics. Of the 124 autopsy-confirmed corticobasal degeneration cases collected from 14 centres, we identified 6 RP-CBD cases (4.8%) who died of advanced disease within 3 years of onset. These RP-CBD cases had different clinical phenotypes including rapid global cognitive decline (N = 2), corticobasal syndrome (N = 2) and Richardson’s syndrome (N = 2). We also studied four corticobasal degeneration cases with an average disease duration of 3 years or less, who died of another unrelated illness (Intermediate-CBD). Finally, we selected 12 age-matched corticobasal degeneration cases out of a cohort of 110, who had a typical gradually progressive course and reached advanced clinical stage (End-stage-CBD). Quantitative analysis showed high overall tau burden (p = 0.2) and severe nigral cell loss (p = 0.47) in both the RP-CBD and End-stage-CBD groups consistent with advanced pathological changes, while the Intermediate-CBD group (mean disease duration = 3 years) had milder changes than End-stage-CBD (p < 0.05). These findings indicated that RP-CBD cases had already developed advanced pathological changes as those observed in End-stage-CBD cases (mean disease duration = 6.7 years), but within a significantly shorter duration (2.5 years; p < 0.001). Subgroup analysis was performed to investigate the cellular patterns of tau aggregates in the anterior frontal cortex and caudate by comparing neuronal-to-astrocytic plaque ratios between six RP-CBD cases, four Intermediate-CBD and 12 age-matched End-stage-CBD. Neuronal-to-astrocytic plaque ratios of Intermediate-CBD and End-stage-CBD, but not RP-CBD, positively correlated with disease duration in both the anterior frontal cortex and caudate (p = 0.02). In contrast to the predominance of astrocytic plaques we previously reported in preclinical asymptomatic corticobasal degeneration cases, neuronal tau aggregates predominated in RP-CBD exceeding those in Intermediate-CBD (anterior frontal cortex: p < 0.001, caudate: p = 0.001) and End-stage-CBD (anterior frontal cortex: p = 0.03, caudate: p = 0.01) as demonstrated by its higher neuronal-to-astrocytic plaque ratios in both anterior frontal cortex and caudate. We did not identify any difference in age at onset, any pathogenic tau mutation or concomitant pathologies that could have contributed to the rapid progression of these RP-CBD cases. Mild TDP-43 pathology was observed in three RP-CBD cases. All RP-CBD cases were men. The MAPT H2 haplotype, known to be protective, was identified in one RP-CBD case (17%) and 8 of the matched End-stage-CBD cases (67%). We conclude that RP-CBD is a distinct aggressive variant of corticobasal degeneration with characteristic neuropathological substrates resulting in a fulminant disease process as evident both clinically and pathologically. Biological factors such as genetic modifiers likely play a pivotal role in the RP-CBD variant and should be the subject of future research.

Abstract
Background We aimed to assess the relationship between levels of a cerebrospinal fluid (CSF) marker of pericyte damage, soluble platelet-derived growth factor receptor β (sPDGFRβ) and CSF markers of blood-brain barrier (BBB) integrity (CSF albumin and CSF/serum albumin ratio) and disease pathology (reduced CSF Aβ42 and elevated CSF total and phosphorylated tau) in Alzheimer’s disease (AD). Methods sPDGFRβ and albumin were measured by sandwich ELISA in ante-mortem CSF from 39 AD and 39 age-matched controls that were grouped according to their biomarker profile (i.e. AD cases t-tau > 400 pg/mL, p-tau > 60 pg/mL and Aβ42 < 550 pg/mL). sPDGFRβ was also measured in matched serum and CSF samples (n = 23) in a separate neurologically normal group for which the CSF/serum albumin ratio had been determined. Results CSF sPDGFRβ level was significantly increased in AD (p = 0.0038) and correlated positively with albumin (r = 0.45, p = 0.007), total tau (r = 0.50, p = 0.0017) and phosphorylated tau (r = 0.41, p = 0.013) in AD but not in controls. CSF sPDGFRβ did not correlate with Aβ42. Serum and CSF sPDGFRβ were positively correlated (r = 0.547, p = 0.0085) in the independent neurologically normal CSF/serum matched samples. Conclusions We provide further evidence of an association between pericyte injury and BBB breakdown in AD and novel evidence that a CSF marker of pericyte injury is related to the severity of AD pathology.

Abstract
Background:
The Army of Women (AOW) is a breast cancer research program of Dr. Susan Love Research Foundation (DSLRF). This initiative aims to accelerate breast cancer (BC) research by engaging and connecting the public with clinical research. To date, over 382,000 women and men, with and without BC, have registered as members. AOW members have full access to a curated repository of supported research studies and educational resources about the science of BC and the clinical research process.
This highly motivated, proactive membership has donated their time, biological samples, and health data to advance studies over the last 10 years. Previous literature has demonstrated that research volunteers are less likely to participate in future studies if not informed of study results. With a membership that has volunteered to participate in over 130 studies, we sought to examine members' interest in receiving study results and preferred dissemination methods.
Methods:
An adaptive, anonymous, online survey collected data on demographics, motivations, engagement behaviors, and attitudes toward research. Participants (N=1,486 to date) were recruited via email (AOW members only) and social media (AOW members and non-members; Facebook posts and ads). Responses were analyzed to understand participant preferences in study result dissemination and outreach methods. For these analyses, the cohort was limited to AOW members who completed the survey and reported past participation in AOW-supported studies.
Results:
Of the 1,486 respondents, 527 (mean age 62.7 years, range 30-85) indicated AOW membership and reported past participation in AOW-supported studies. The majority was female (99%) and non-Hispanic white (94%). Over half (65.46%) reported a history of BC.
Of participants, 71% would like to learn about scientific results from studies that included members of the AOW. The preferred dissemination frequency and methods are monthly via email (61%) or social media (26%). Based on participants' reported social media use, dissemination through Facebook (74%) would yield the greatest reach – followed by YouTube (24%), Instagram (22%), LinkedIn (15%), Twitter (14%), and Snapchat (4%).
In addition to updates about study results, 75% of participants want to hear about publications from past AOW-supported studies. Importantly, a majority (84%) of those also want access to a brief overview and lay explanation of the publication. The preferred methods of dissemination for these publications and lay overviews are AOW newsletters (84%), a dedicated menu on the AOW website (51%), social media (29%), and blog posts on the DSLRF website (16%).
Conclusions:
As in prior literature, clinical research participants in the AOW program indicate a high preference for receiving updates and staying informed about past study results. Participants indicate that they prefer to receive these results through emailed newsletters, websites, and social media. Researchers should consider these low-cost methods as they plan for result dissemination. Our findings support that volunteers want to be informed about results of their participation. This provides a clear opportunity for researchers to keep volunteers engaged and interested in participating in future clinical research.

Abstract
AIMS There is evidence that accumulation of α-synuclein (α-syn) in Parkinson's disease (PD) and dementia with Lewy bodies (DLB) results from impaired removal of α-syn rather than its overproduction. Kallikrein-6 (KLK6), calpain-1 (CAPN1) and cathepsin-D (CTSD) are among a small number of proteases that cleave α-syn and are dysregulated in PD and DLB. Our aim in this study was to determine whether protease activity is altered in another α-synucleinopathy, multiple system atrophy (MSA), and might thereby modulate the regional distribution of α-syn accumulation. METHODS mRNA and protein level and/or activity of KLK6, CAPN1 and CTSD were measured and assessed in relation to α-syn load in multiple brain regions (posterior frontal cortex, caudate nucleus, putamen, occipital cortex, pontine base and cerebellar white matter), in MSA (n = 20) and age-matched postmortem control tissue (n = 20). RESULTS CTSD activity was elevated in MSA in the pontine base and cerebellar white matter. KLK6 and CAPN1 levels were elevated in MSA in the putamen and cerebellar white matter. However, the activity or level of these proteolytic enzymes did not correlate with the regional distribution of α-syn. CONCLUSIONS Accumulation of α-syn in MSA is not due to reduced activity of the proteases we have studied. We suggest that their upregulation is likely to be a compensatory response to increased α-syn in MSA.

Abstract
Abstract
Rationale: People living with metastatic breast cancer face unique challenges, which have not been well characterized. The aim of the MBCCD was to characterize the MBC patient experience in order to identify and address potential areas of need in this underserved population.
Method: We crowdsourced input and gathered free-text data from 353 people living with MBC to document the breadth of challenges affecting quality of life. From the responses, we developed a new measure (SHINE) with 79 patient-driven items regarding the experience of MBC, including verbatim statements from crowdsourcing data. Validated quality of life scales, clinical information, and demographic data were also collected. Participants were recruited from Dr. Susan Love Research Foundation's Army of Women® and other advocacy organizations; 515 completed the questionnaire. Confirmatory and exploratory factor analyses were conducted to assess model fit for SHINE and to identify subscales. Next, differences in MBC-specific concerns and experiences as a function of age, marital status, financial status, education, children, metastatic site location(s), and current medical treatment were examined with ANOVAs and t-tests.
Results: Factor analyses indicated good model fit (CFI=.96, RMSEA=.05, SRMR=.04) for a 36-item scale of MBC-specific concerns and experiences with nine subscales: 1) Employment/achievement, 2) Finances, 3) Insurance, 4) Mortality/uncertainty, 5) Activity disruption, 6) Concern for others, 7) Social isolation/withdrawal, 8) Self-concept disruption, 9) Benefit finding. A within-subjects ANOVA revealed that participants were most bothered by mortality/uncertainty concerns, followed by activity disruption, financial, employment/achievement, and insurance concerns, respectively (F(4,508)=111.38, p<0.01). Additionally, participants endorsed strongest agreement with benefit finding, followed by concern for others, self-concept disruption, and social isolation/withdrawal (F(4,508)=101.53, p<.01). Participants younger than 50 years and those with lower financial status reported higher concerns on all subscales (ps<0.01), except for benefit finding (ps>0.18). Participants with a child under 18 living at home, those on combination therapies, and those with metastases to multiple sites or bone only reported higher concerns on several subscales (ps<0.05). Being married was significantly associated with higher concern for others and lower concern about finances (ps<0.02). Education was not significantly related to any subscale.
Conclusions: Several important concerns and experiences related to MBC are not captured adequately in existing measures. This study developed a new measure (SHINE), which reliably assessed these disease-specific concerns and experiences in 515 adults living with MBC. Concerns regarding mortality and uncertainty were most prominent. Specific demographic and medical characteristics modified responses on eight subscales, but not on the benefit finding subscale. Findings can aid the development of supportive care efforts that address areas of need (e.g., concerns about mortality and uncertainty) in this understudied medical population.

Abstract
Abstract
Rationale: Research has identified risk and protective factors that predict health and well-being in adults with breast cancer, but this work has been focused largely on women with early-stage disease. Metastatic breast cancer (MBC) patients report worse psychological health and poorer quality of life compared to those with early-stage breast cancer. We investigated whether a newly developed measure of MBC-specific concerns and experiences, the Survey of Health, Impact, Needs, and Experiences (SHINE), is associated with psychological health, illness management, and health behaviors in a sample of MBC patients.
Method: SHINE includes 36 items capturing the experience of MBC, including verbatim statements from previously collected crowdsourcing data. Participants (N=515) were recruited from Dr. Susan Love Research Foundation's Army of Women® and other advocacy organizations. Participants also completed measures of psychological health (i.e., depression, anxiety), illness management (i.e., self-efficacy for managing medications/treatments and symptoms), and health behaviors (i.e., sleep, degree of moderate physical activity). The nine SHINE subscales, along with age, marital status, financial status, children, metastatic site location(s), and current medical treatment(s), were entered as simultaneous predictors in a multivariate regression. Psychological health, illness management, and health behaviors were entered as dependent variables in separate models.
Results: With demographic and medical variables controlled, MBC-specific concerns were associated significantly with depressive symptoms (ΔR2=.38), anxiety (ΔR2=.37), efficacy for medication/treatment management (ΔR2=.08), efficacy for symptom management (ΔR2=.32), sleep disruption (ΔR2 =.10), and physical activity (ΔR2=.17), with all ps<.01. Specifically, higher depressive symptoms and anxiety were associated greater mortality/uncertainty concerns (ps<.01), greater social isolation/withdrawal (ps<.01), and higher self-concept disruption (ps<.02). Anxiety was uniquely associated with greater financial concerns (p<.02), whereas depression was uniquely associated with fewer positive experiences (p<.05). Higher self-efficacy for managing symptoms was related to more positive experiences, higher mortality concerns, and more self-concept and activity disruption (ps<.01), whereas higher efficacy for managing medications/treatments was associated with lower social isolation/withdrawal (p<.03). More sleep disruption was associated with higher concern for others (p<.05), and less physical activity was associated with more activity disruption (p<.01).
Conclusions: After controlling for demographic and medical characteristics, MBC-specific concerns were related significantly to psychological health, self-efficacy for illness management, and health behaviors. Mortality/uncertainty concerns, social isolation/withdrawal, and self-concept disruption were especially important correlates of depressive symptoms, anxiety, and MBC-related self-efficacy. Higher concern for others was related to more sleep disruption. Approaches that address these MBC-specific concerns and promote positive experiences may be beneficial for patients.

Abstract
Aim To investigate the effects of tacrolimus (TC) and everolimus (EV) on non-alcoholic steatohepatitis (NASH) induced by high fat, high cholesterol and fructose (fast food) diet in C57BL/6J mice. Materials and Methods C57BL/6J mice were divided into four groups (n=8). 1) Standard Chow (SC); 2) Fast food (FF) diet; 3) FF + Tacrolimus (TC, 1mg/kg) and; 4) FF + Everolimus (EV, 1mg/kg) and treated for 16 weeks. Serum and tissue samples were analyzed for evidence of inflammation, fibrosis, lipogenesis, and apoptosis. Results TC and EV treatments significantly reduced the hepatic lipid accumulation, improved liver-body weight ratio, blood biochemistry, and insulin resistance in mice fed with FF diet. However, inflammation, enlarged portal tracts, and fibrosis were pronounced in EV treated group. The lipogenic parameters, Peroxisome proliferator-activated receptor gamma (PPAR-γ), Sterol regulatory element-binding protein 1(SREBP-1), mammalian target of rapamycin (m-TOR), Stearoyl-CoA desaturase-1 (SCD-1) and fatty acid translocase (CD36) were significantly down-regulated in livers of TC and EV treated groups as compared to FF group. TC improved Bcl2/Bax ratio, decreased apoptosis, CYP2E1 protein expression and liver fibrosis levels, however, EV offered no such protection. Further, in an In-vitro model of lipotoxicity using the mouse hepatocyte (AML-12) cell line, treatment with TC and EV significantly reduced lipid accumulation and lipogenic and apoptotic markers induced with palmitic acid. Conclusion In FF diet induced model of NASH, both TC and EV inhibited hepatic lipid accumulation and improved metabolic parameters such as insulin resistance and dyslipidemia. However, mice administered with EV exhibited inflammatory and fibrotic responses despite reduced hepatic steatosis.

Abstract
BACKGROUND Sagittal ratio values (SRVs) of cervical vertebrae are used for ante-mortem diagnosis of cervical vertebral stenotic myelopathy, but intraobserver and interobserver variability in measurement may influence radiographic interpretation of vertebral stenosis in horses with neurological disease. OBJECTIVES To determine intraobserver repeatability in SRVs, intra- and interobserver agreement in SRVs and whether or not agreement was influenced by animal age. ANIMALS Forty-two horses (>1 year old) with neurological disease from which laterolateral computed radiographic images of C2-C7 were obtained. METHODS Four observers made measurements from C2 to C7 for each horse and interobserver agreement for intra- and intervertebral SRVs was determined using Bland-Altman analysis (acceptable agreement: limits of agreement [LOA] ≤ 0.05) on all horses and those ≤3 (n = 25) and >3 (n = 17) years old. Each observer also made repeated measurements for 10 horses and intraobserver repeatability and agreement were determined. RESULTS Adequate intraobserver repeatability was achieved for 6 sites. Within observers, paired measurements had a median difference ≤5.7%, but a large range in differences often occurred, most frequently at intervertebral sites. For C5, C6, C7, and C3-4, LOA ≤ 0.05 were achieved by at least 1 observer. With the exception of C5 for 1 pair, LOA were >0.05 for interobserver agreement, regardless of animal age. LOA were largest at intervertebral sites. CONCLUSIONS AND CLINICAL IMPORTANCE Within and between observers, measurement error may limit the diagnostic accuracy of SRVs and result in discrepancies of diagnosis and treatment and warrants consideration when used clinically in horses with neurological disease.

Abstract
REASONS FOR PERFORMING STUDY Although fasciolosis is an important livestock disease worldwide, the public health importance of human fasciolosis has increased in recent years and it is recognised as an important re-emerging zoonotic disease, its epidemiology and pathogenicity in donkeys, and the epidemiological role they may play have not been determined. OBJECTIVES To investigate the epidemiology and pathogenicity of fasciolosis in donkeys. STUDY DESIGN Cross-sectional coprological and retrospective post-mortem study. METHODS Faecal samples collected from 803 randomly selected working donkeys from the central region of Ethiopia were analysed by a sedimentation-centrifugation-flotation technique. Further data on liver-flukes and associated pathologies were obtained by routine post mortem examinations of 112 donkeys, subjected to euthanasia on welfare grounds or died. Data were analysed using a generalised linear model and multivariate binary logistic regression in R statistical package with significance level of statistical tests set at P<0.05. RESULTS Infection prevalences of 44.4% and 41.9% were obtained in coprologically and post mortem examined donkeys, respectively, irrespective of their age. Both Fasciola hepatica and Fasciola gigantica were identified with the mean infection intensity of 30 flukes. Older donkeys (≥8 years) were found harbouring a significantly higher worm burden (P<0.0001). Gross and histopathologies of hyperplasia and thickening of the bile ducts, fibrosis of large portal areas and irregular bile duct proliferation and hypertrophy were noted. CONCLUSIONS The high infection prevalence of fasciolosis and the associated hepatic pathologies in working donkeys shows not only the susceptibility of donkeys and the impact it has on their health, but also indicates the important role they can play in the epidemiology of both livestock and human fasciolosis. These further demonstrate the need for these animals to be considered in the overall epidemiological studies and for sound control strategies and prevention of fasciolosis. Ethical animal research: The research underwent ethical review and the use of animals was approved by the Directors of The Donkey Sanctuary. Consent of the owners was obtained to use their animals.

Abstract
Alzheimer’s disease (AD) increases dramatically in patients with ischaemic stroke. Monomeric C-reactive protein (mCRP) appears in the ECM of ischaemic tissue after stroke, associating with microvasculature, neurons and AD-plaques, Aβ, also, being able to dissociate native-CRP into inflammatory, mCRP in vivo. Here, mCRP injected into the hippocampal region of mice was retained within the retrosplenial tract of the dorsal 3rd ventrical and surrounding major vessels. Mice developed behavioural/cognitive deficits within 1 month, concomitant with mCRP staining within abnormal looking neurons expressing p-tau and in beta-amyloid 1-42-plaque positive regions. mCRP co-localised with CD105 in microvessels suggesting angiogenesis. Phospho-arrays/Western blotting identified signalling activation in endothelial cells and neurons through p-IRS-1, p-Tau and p-ERK1/2-which was blocked following pre-incubation with mCRP-antibody. mCRP increased vascular monolayer permeability and gap junctions, increased NCAM expression and produced haemorrhagic angiogenesis in mouse matrigel implants. mCRP induced tau244–372 aggregation and assembly in vitro. IHC study of human AD/stroke patients revealed co-localization of mCRP with Aβ plaques, tau-like fibrils and IRS-1/P-Tau positive neurons and high mCRP-levels spreading from infarcted core regions matched reduced expression of Aβ/Tau. mCRP may be responsible for promoting dementia after ischaemia and mCRP clearance could inform therapeutic avenues to reduce the risk of future dementia.

Abstract
OBJECTIVE This study aimed to provide an indication of the prevalence and severity of anthelmintic resistance (AR) in the Australian sheep industry by compiling the results of faecal worm egg count reduction tests (FECRTs). METHODS Government and private parasitology laboratories, pharmaceutical companies and veterinarians known to have conducted FECRTs were asked to provide results that conformed to Australian and New Zealand standard diagnostic procedures. RESULTS Data were available from a total of 390 tests, with larval differentiation conducted in 222 cases. Pooled results from all states for the macrocyclic lactone (ML) class showed a lower prevalence of AR against combined species for moxidectin (54%) compared with abamectin (77%) and ivermectin (87%). Analysis by state revealed higher levels of ML-resistant Teladorsagia sp. in Tasmania and Western Australia than in other states and ML-resistant Haemonchus sp. was more frequently detected in New South Wales. CONCLUSION This compilation of results of FECRTs conducted by Australian parasitology laboratories in 2009-12 showed widespread AR of the common sheep nematodes (Teladorsagia, Trichostrongylus and Haemonchus) to all broad-spectrum anthelmintics, with the exception of monepantel, whether used singly or in combination.

Abstract
BACKGROUND Treatment options for wild-type BRAF melanoma patients remain limited. Selumetinib, a MEK 1/2 inhibitor, suppresses pERK levels independent of BRAF and NRAS mutation status, and combination with docetaxel has demonstrated synergy in xenograft models. The aim of this study was to assess the efficacy and safety of selumetinib plus docetaxel as first-line treatment in patients with wild-type BRAF advanced melanoma. PATIENTS AND METHODS In this double-blind multicentre phase II trial patients with wild-type BRAF melanoma were randomized (1:1) to docetaxel with selumetinib or placebo. Docetaxel 75 mg/m(2) was administered intravenously every 3 weeks up to six cycles. Selumetinib 75 mg or placebo was given orally twice daily until disease progression or unacceptable toxicity. The primary end point was progression-free survival (PFS). Tumour NRAS mutation status was analysed retrospectively and correlated with treatment outcomes. RESULTS Eighty-three patients were randomized to docetaxel plus selumetinib (n = 41) or docetaxel plus placebo (n = 42). The PFS hazard ratio (HR) (selumetinib:placebo) was 0.75 [90% confidence interval (CI) 0.50-1.14; P = 0.130], with a median PFS of 4.23 months (90% CI 3.63-6.90) for docetaxel plus selumetinib and 3.93 months (90% CI 2.07-4.16) for docetaxel alone. There was no significant difference in overall survival. The objective response rate was 32% with selumetinib versus 14% with placebo (P = 0.059). In a retrospective subset analysis, NRAS mutation status did not affect significantly upon clinical outcomes in either arm. The combination of docetaxel and selumetinib could be administered effectively to patients with metastatic melanoma, although the combination was less well tolerated than docetaxel alone. CONCLUSIONS The combination of docetaxel with selumetinib showed no significant improvement in PFS compared with docetaxel alone, although more patients showed a response to combination therapy. We found no evidence to support using tumour NRAS mutation as a basis for selecting patients for combined MEK inhibitor and chemotherapy. CLINICAL TRIAL DOC-MEK (EudraCT no: 2009-018153-23).

Abstract
Eleven susceptibility loci for late-onset Alzheimer's disease (LOAD) were identified by previous studies; however, a large portion of the genetic risk for this disease remains unexplained. We conducted a large, two-stage meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry. In stage 1, we used genotyped and imputed data (7,055,881 SNPs) to perform meta-analysis on 4 previously published GWAS data sets consisting of 17,008 Alzheimer's disease cases and 37,154 controls. In stage 2, 11,632 SNPs were genotyped and tested for association in an independent set of 8,572 Alzheimer's disease cases and 11,312 controls. In addition to the APOE locus (encoding apolipoprotein E), 19 loci reached genome-wide significance (P < 5 × 10(-8)) in the combined stage 1 and stage 2 analysis, of which 11 are newly associated with Alzheimer's disease.

Abstract
Angiogenesis has been shown to be important in tumor growth and metastasis. Thalidomide, an oral sedative, has recently been found to inhibit angiogenesis. We therefore set out to ask whether thalidomide can be used as therapy for breast cancer. In a mouse model of breast cancer, we found that thalidomide alone did not suppress tumor growth. However, mice treated with thalidomide in combination with cytoxan and adriamycin had significantly smaller tumors than those given the two chemotherapeutic agents alone (3,432 +/- 303 mm(3) versus 4,643 +/- 203 mm(3), p = 0.0005). We proceeded to administer thalidomide together with chemotherapy to seven breast cancer patients in the context of a Phase I trial. Side effects attributed to thalidomide were minimal, and included constipation and a rash. We concluded that an approach at cancer therapeutics combining an antiangiogenic agent such as thalidomide with conventional chemotherapy may be feasible and deserves further studies.

Abstract
The objective of this study was to identify risk factors for superficial digital flexor (SDF) tendinopathy in Thoroughbred horses in steeplechase races in the United Kingdom. Potential risk factors for SDF tendinopathy were studied between 1st January 2001 and 31st December 2009 using a cohort study design with 648 injuries sustained in 102,894 starts. Potential risk factors were screened using univariable logistic regression prior to multivariable model building. In the final multivariable model, 12 statistically significant risk factors were identified. Variables that increased the odds of SDF tendinopathy included firmer going, increased horse age, and racing in the summer compared to other seasons. Variables that decreased the odds included having a higher official rating and the number of starts in the preceding days. Fewer and different risk factors were identified than in an equivalent model of SDF tendinopathy in hurdle racing, highlighting potential differences between these disciplines. Further collection of training and racecourse information would be beneficial and may help to explain further some of the associations identified in this study. The results will facilitate the development of strategies to improve overall safety of horses in UK steeplechase racing.

Abstract
The faecal egg count (FEC) is the most widely used means of quantifying the nematode burden of horses, and is frequently used in clinical practice to inform treatment and prevention. The statistical process underlying the FEC is complex, comprising a Poisson counting error process for each sample, compounded with an underlying continuous distribution of means between samples. Being able to quantify the sources of variability contributing to this distribution of means is a necessary step towards providing estimates of statistical power for future FEC and FECRT studies, and may help to improve the usefulness of the FEC technique by identifying and minimising unwanted sources of variability. Obtaining such estimates require a hierarchical statistical model coupled with repeated FEC observations from a single animal over a short period of time. Here, we use this approach to provide the first comparative estimate of multiple sources of within-horse FEC variability. The results demonstrate that a substantial proportion of the observed variation in FEC between horses occurs as a result of variation in FEC within an animal, with the major sources being aggregation of eggs within faeces and variation in egg concentration between faecal piles. The McMaster procedure itself is associated with a comparatively small coefficient of variation, and is therefore highly repeatable when a sufficiently large number of eggs are observed to reduce the error associated with the counting process. We conclude that the variation between samples taken from the same animal is substantial, but can be reduced through the use of larger homogenised faecal samples. Estimates are provided for the coefficient of variation (cv) associated with each within animal source of variability in observed FEC, allowing the usefulness of individual FEC to be quantified, and providing a basis for future FEC and FECRT studies.

Abstract
The analysis of biomarkers in exhaled breath (EB) and exhaled breath condensate (EBC) may allow non-invasive and repeatable assessment of respiratory health and disease in mammals. Compared to human medicine, however, research data from EB and EBC analysis in veterinary medicine are limited and more patient variables influencing concentrations of EB/EBC analytes may be present. In addition, variations in methodologies between studies may influence results. A comparison of the approaches used in veterinary research by different groups may aid in the identification of potentially reliable and repeatable biomarkers suitable for further investigation. To date, changes in acid-base status and increased concentrations of inflammatory mediators have been the main findings in studies of pulmonary disease states in animals. Whilst these biomarkers are unlikely to represent specific and sensitive diagnostic parameters, they do have potential application in monitoring disease progression and treatment response.

Abstract
OBJECTIVE Develop a computer simulation model that uses daily meteorological data and farm management practices to predict populations of Trichostrongylus colubriformis, Haemonchus contortus and Teladorsagia (Ostertagia) circumcincta and the evolution of anthelmintic resistance within a sheep flock. Use the model to explore if increased refugia, provided by leaving some adult sheep untreated, would delay development of anthelmintic resistance without compromising nematode control. PROCEDURES Compare model predictions with field observations from a breeding flock in Armidale, NSW. Simulate the impact of leaving 1-10% of adult sheep untreated in diverse sheep-grazing systems. RESULTS Predicted populations of Tr. colubriformis and T. circumcincta were less than those observed in the field, attributed to nutritional stress experienced by the sheep during drought and not accounted for by the model. Observed variation in faecal egg counts explained by the model (R(2) ) for these species was 40-50%. The H. contortus populations and R(2) were both low. Leaving some sheep untreated worked best in situations where animals were already grazing or were moved onto pastures with low populations of infective larvae. In those cases, anthelmintic resistance was delayed and nematode control was maintained when 1-4% of adult stock remained untreated. CONCLUSIONS In general, the model predicted that leaving more than 4% of adults untreated did not sufficiently delay the development of anthelmintic resistance to justify the increased production risk from such a strategy. The choice of a drug rotation strategy had an equal or larger effect on nematode control, and selection for resistance, than leaving 1-10% of adults untreated.

Abstract
REASONS FOR PERFORMING STUDY Validation of a reliable, noninvasive clinical test for quantification of equine orocaecal transit time (OCTT) is required. This would facilitate an evidence-based approach to investigation and treatment of equine small intestinal disorders. OBJECTIVES 1) Comparison of the lactose (13) C-ureide breath test (LUBT) with the hydrogen breath test (H(2) BT) for OCTT measurement. 2) Identification of the characteristics of gastrointestinal microbial glycosylureide hydrolase activity in vitro. 3) Production of an optimised protocol for the LUBT for in vivo measurement of equine OCTT. HYPOTHESIS Significant lactose (13) C-ureide ((13) C-LU) hydrolase activity is restricted to the large bowel. The rate of expiratory (13) CO(2) production after ingestion of the isotope will provide an indirect quantifiable measure of orocaecal transit rate. Requisite bacterial activity may be enhanced by a primer dose of unlabelled substrate as shown in Man. METHODS Combined LUBT and H(2) BT were performed in 8 healthy individuals. Analysis of sequential end expiratory breath samples was used to calculate OCTT and results compared. Digestion of (13) C-LU was investigated in vitro using fresh faecal material or intestinal aliquots collected post mortem. Isotopic fermentation rate was measured by rate of appearance of (13) CO(2) . RESULTS Peaks in expiratory (13) CO(2) occurred in all individuals after ingestion of the labelled test meal, whereas H(2) expiration was variable. Both faecal and intestinal microbial digestion of (13) C-LU were maximised by prior exposure to (12) C-LU. Induced bacterial glucoseureide hydrolase activity was significantly greater in the caecum than in the small intestine (n = 10, P<0.05). CONCLUSIONS Significant (13) C-LU digestion is restricted to the equine large intestine under normal conditions, and is enhanced by prior exposure to (12) C-LU, making (13) C-LU a suitable noninvasive marker of equine OCTT. The LUBT is more reliable than the H(2) BT for measurement of equine OCTT.

Abstract
REASONS FOR PERFORMING STUDY Application of the lactose (13) C-ureide breath test (LUBT) for measurement of equine orocaecal transit time (OCTT) has not been reported previously. The ability to assess OCTT noninvasively, and to investigate its relationship to gastric emptying rate and small intestinal transit, would be of both clinical and research value. OBJECTIVES 1) Assessment of the LUBT in healthy horses, with comparison of induced versus noninduced test protocols. 2) Application of a new dual stable isotope breath test (lactose (13) C-ureide and (13) C-octanoic acid) for gastrointestinal transit measurement. HYPOTHESIS The LUBT will allow quantification of equine OCTT, and test efficacy will be enhanced by prior administration of lactose (12) C-ureide as shown in vitro. The dual tracer breath test will permit simultaneous measurement of gastric emptying, OCTT and small bowel transit times. METHODS Induced and noninduced LUBTs were performed in 3 healthy mature horses in randomised order using a standard test meal and protocol. Combined LUBT and (13) C-octanoic acid breath tests ((13) C-OABT) were performed in 4 individuals on 4 occasions at weekly intervals. Expiratory isotopic recovery was modelled to allow generation of gastric emptying data, small bowel transit times and caecal transit parameters. RESULTS The induction protocol for the LUBT increased the rate and magnitude of expiratory (13) CO(2) significantly. Mean ± s.d. values for OCTT, caecal lag phase (t(lag) ) and caecal t(1/2) using the induced LUBT were 3.24 ± 0.65 h, 5.62 ± 1.22 h and 6.31 ± 1.21 h, respectively. Dual stable isotope tests resulted in the production of 2 discrete peaks in expiratory (13) CO(2) in 15/16 tests from which gastric t(1/2), OCTT and small bowel transit (SBT) parameters could be calculated. CONCLUSIONS The induced LUBT provides a reliable noninvasive measure of equine OCTT and can be paired with the (13) C-OABT to provide further information about small intestinal motility.
