Abstract
OBJECTIVES To report the outcome, frequency of complications and potential prognostic factors associated with surgical repair of superficial digital flexor tendon (SDFT) luxation in dogs. MATERIALS AND METHODS Medical records from 10 referral hospitals were reviewed retrospectively for cases of SDFT luxation in dogs that underwent surgical stabilisation. Signalment, clinical presentation, diagnostic imaging, surgical method, type and length of post-operative limb immobilisation, nature of and length of exercise restriction, presence of post-operative complications and outcomes were recorded. Data were summarised descriptively and prognostic risk factors assessed for association with surgical outcome using risk ratios. RESULTS Forty-eight cases were included. A successful surgical outcome was recorded in 35 of 48 (73%) cases. Re-luxation of the SDFT occurred in seven of 48 (15%). Six out of 48 (13%) had a persistent lameness despite a stable non-luxating SDFT. A high frequency of post-operative complications occurred (71%), with the majority resolved medically. The risk of surgical failure was 60% higher (risk ratio 1.6, 95% confidence interval 1.1 to 2.4) where absorbable suture material was used compared to non-absorbable suture material. Surgical failure was more common in cases managed with non-rigid immobilisation post-operatively (57% failure) compared to cases managed with rigid immobilisation (19% failure), although this result was not statistically significant. Limb immobilisation of 6 weeks or longer did not significantly affect surgical outcome, compared to shorter periods of exercise restriction or limb immobilisation. CLINICAL SIGNIFICANCE A good outcome can be expected following surgical stabilisation of SDFT luxation. The use of non-absorbable suture was associated with a more successful surgical outcome.

Abstract
River flow regimes have been transformed by groundwater and surface water management operations globally, prompting widespread ecological responses. Yet, empirical evidence quantifying the simultaneous effects of groundwater and surface water management operations on freshwater ecosystems remains limited. This study combines a multi-decadal freshwater invertebrate dataset (1995-2016) with groundwater model outputs simulating the effects of different anthropogenic flow alterations (e.g. groundwater abstraction, effluent water returns) and river discharges. A suite of flow alteration- and flow-ecology relationships were modelled that tested different invertebrate community responses (taxonomic, functional, flow response guilds, individual taxa). Most flow alteration-ecology relationships were not statistically significant, highlighting the absence of consistent, detectable ecological responses to long-term water management operations. A small number of significant statistical models provided insights into how flow alterations transformed specific ecological assets; including Ephemeroptera, Plecoptera and Trichoptera taxa which are rheophilic in nature being positively associated with groundwater abstraction effects reducing river discharges by 0-15%. This represents a key finding from a water resource management operation perspective given that such flow alteration conditions were observed on average in over two-thirds of the study sites examined. In a small number of instances, specific invertebrate responses displayed relative declines associated with the most severe groundwater abstraction effects and artificial hydrological inputs (predominantly effluent water returns). The strongest flow-ecology relationships were recorded during spring months, when invertebrate communities were most responsive to antecedent minimum and maximum discharges, and average flow conditions in the preceding summer months. Results from this study provide new evidence indicating how groundwater and surface water resources can be managed to conserve riverine ecological assets. Moreover, the ensemble of flow alteration- and flow-ecology relationships established in this study could be used to guide environmental flow strategies. Such findings are of global importance given that future climatic change and rising societal water demands are likely to further transform river flow regimes and threaten freshwater ecosystems.

Abstract
We report details of an experimental platform implemented at the National Ignition Facility to obtain in situ powder diffraction data from solids dynamically compressed to extreme pressures. Thin samples are sandwiched between tamper layers and ramp compressed using a gradual increase in the drive-laser irradiance. Pressure history in the sample is determined using high-precision velocimetry measurements. Up to two independently timed pulses of x rays are produced at or near the time of peak pressure by laser illumination of thin metal foils. The quasi-monochromatic x-ray pulses have a mean wavelength selectable between 0.6 Å and 1.9 Å depending on the foil material. The diffracted signal is recorded on image plates with a typical 2θ x-ray scattering angle uncertainty of about 0.2° and resolution of about 1°. Analytic expressions are reported for systematic corrections to 2θ due to finite pinhole size and sample offset. A new variant of a nonlinear background subtraction algorithm is described, which has been used to observe diffraction lines at signal-to-background ratios as low as a few percent. Variations in system response over the detector area are compensated in order to obtain accurate line intensities; this system response calculation includes a new analytic approximation for image-plate sensitivity as a function of photon energy and incident angle. This experimental platform has been used up to 2 TPa (20 Mbar) to determine the crystal structure, measure the density, and evaluate the strain-induced texturing of a variety of compressed samples spanning periods 2-7 on the periodic table.

Abstract
BACKGROUND Two vaccines against Clostridioides difficile infections (CDI) are currently in phase III trials. To enable decision-making on their use in public health programs, national disease epidemiology is necessary. OBJECTIVES To determine the epidemiology of hospital-acquired CDI (HA-CDI) and community-associated CDI (CA-CDI) in Canada using provincial surveillance data and document discrepancies in CDI-related definitions among provincial surveillance programs. METHODS Publicly-available CDI provincial surveillance data from 2011 to 2016 that distinguished between HA-CDI and CA-CDI were included and the most common surveillance definitions for each province were used. The HA-, CA-CDI incidence rates and CA-CDI proportions (%) were calculated for each province. Both HA- and CA-CDI incidence rates were examined for trends. Types of disparities were summarized and detailed discrepancies were documented. RESULTS Canadian data were analyzed from nine provinces. The HA-CDI rates ranged from 2.1/10,000 to 6.5/10,000 inpatient-days, with a decreasing trend over time. Available data on CA-CDI showed that both rates and proportions have been increasing over time. Discrepancies among provincial surveillance definitions were documented in CDI case classifications, surveillance populations and rate calculations. CONCLUSION In Canada overall, the rate of HA-CDI has been decreasing and the rate of CA-CDI has been increasing, although this calculation was impeded by discrepancies in CDI-related definitions among provincial surveillance programs. Nationally-adopted common definitions for CDI would enable better comparisons of CDI rates between provinces and a calculation of the pan-Canadian burden of illness to support vaccine decision-making.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
PURPOSE OF REVIEW The aim of this paper was to review the recent international developments in health promotion and wellness initiatives targeting chronic disease prevention and management for adults with intellectual and developmental disabilities (IDD) targeting type 2 diabetes (T2D). RECENT FINDINGS There has been one diabetes prevention program (STOP) and two self-management T2D education programs (DESMOND-ID; OK diabetes) adapted for this population. All three programs have been adapted from other theoretically informed and tested programs developed for the general population. Each program has employed co-design and co-production techniques with all stakeholders. The three programs all target the high-risk lifestyle factors that can lead to T2D and contribute to poor glycaemia control, and have undertaken randomized-feasibility studies, the results of which are promising. SUMMARY This paper shows that any health promotion and wellness initiatives need to be tailored and reasonable adjustments made in order to address this population's cognitive impairments and communication difficulties.

Abstract
AIMS To undertake a feasibility randomized controlled trial of supported self-management vs treatment as usual in a population of adults with obesity, Type 2 diabetes and an intellectual disability. METHODS We conducted an individually randomized feasibility trial. Participants were adults aged >18 years with a mild or moderate intellectual disability, living in the community with Type 2 diabetes, on any therapy other than insulin. Participants had mental capacity to consent to research and the intervention. Inclusion criteria included HbA1c > 48 mmol/mol (6.5%), BMI >25 kg/m2 , or self-reported physical activity below national guideline levels. The experimental intervention was standardized supported self-management delivered by diabetes specialist nurses plus treatment as usual, compared with treatment as usual alone. Feasibility outcomes included: recruitment and retention; intervention acceptability and feasibility; data collection and completeness for physiological state and values for candidate primary outcomes (HbA1c and BMI). RESULTS A total of 82 participants (89% of those contacted and eligible) were randomized. All supported self-management sessions were completed by 35/41 participants (85%); only four completed no sessions. Data on the follow-up candidate primary outcomes HbA1c and BMI were obtained for 75/82 (91%) and 77/82 participants (94%), respectively. The mean baseline HbA1c was 56±16.5 mmol/mol (7.3±1.5%) and the mean BMI was 34±7.6 kg/m2 . CONCLUSIONS Adherence to supported self-management and willingness to have blood taken for outcome measurement was good. A definitive randomized controlled trial is feasible in this population.

Abstract
We have designed, built, and successfully fielded a highly efficient and gated Bragg crystal spectrometer for x-ray Thomson scattering measurements on the National Ignition Facility (NIF). It utilizes a cylindrically curved Highly Oriented Pyrolytic Graphite crystal. Its spectral range of 7.4-10 keV is optimized for scattering experiments using a Zn He-α x-ray probe at 9.0 keV or Mo K-shell line emission around 18 keV in second diffraction order. The spectrometer has been designed as a diagnostic instrument manipulator-based instrument for the NIF target chamber at the Lawrence Livermore National Laboratory, USA. Here, we report on details of the spectrometer snout, its novel debris shield configuration and an in situ spectral calibration experiment with a Brass foil target, which demonstrated a spectral resolution of E/ΔE = 220 at 9.8 keV.

Abstract
A magnetic particle time-of-flight (MagPTOF) diagnostic has been designed to measure shock- and compression-bang time using D(3)He-fusion protons and DD-fusion neutrons, respectively, at the National Ignition Facility (NIF). This capability, in combination with shock-burn weighted areal density measurements, will significantly constrain the modeling of the implosion dynamics. This design is an upgrade to the existing particle time-of-flight (pTOF) diagnostic, which records bang times using DD or DT neutrons with an accuracy better than ±70 ps [H. G. Rinderknecht et al., Rev. Sci. Instrum. 83, 10D902 (2012)]. The inclusion of a deflecting magnet will increase D(3)He-proton signal-to-background by a factor of 1000, allowing for the first time simultaneous measurements of shock- and compression-bang times in D(3)He-filled surrogate implosions at the NIF.

Abstract
OBJECTIVES To describe the characteristics and management of individuals attending hospital with self-harm and assess changes in management and service quality since an earlier study in 2001, a period in which national guidance has been available. DESIGN Observational study. SETTING A stratified random sample of 32 hospitals in England, UK. PARTICIPANTS 6442 individuals presenting with 7689 episodes of self-harm during a 3-month audit period between 2010 and 2011. OUTCOME Self-harm episodes, key aspects of individual management relating to psychosocial assessment and follow-up, and a 21-item measure of service quality. RESULTS Overall, 56% (3583/6442) of individuals were women and 51% (3274/6442) were aged under 35 years. Hospitals varied markedly in their management. The proportion of episodes that received a psychosocial assessment by a mental health professional ranged from 22% to 88% (median 58%, IQR 48-70%); the proportion of episodes resulting in admission to general hospitals varied from 22% to 85% (median 54%, IQR 41-63%); a referral for specialist mental health follow-up was made in 11-64% of episodes (median 28%, IQR 22-38%); a referral to non-statutory services was made in 4-62% of episodes (median 15%, IQR 8-23%); 0-21% of episodes resulted in psychiatric admission (median 7%, QR 4-12%). The specialist assessment rate varied by method of harm; the median rate for self-cutting was 45% (IQR 28-63%) vs 58% (IQR 48-73%) for self-poisoning. Compared with the 2001 study, there was little difference in the proportion of episodes receiving specialist assessment; there was a significant increase in general hospital admission but a decrease in referrals for specialist mental health follow-up. However, scores on the service quality scale had increased from a median of 11.5-14.5 (a 26% increase). CONCLUSIONS Services for the hospital management of self-harm remain variable despite national guidelines and policy initiatives. We found no evidence for increasing levels of assessment over time but markers of service quality may have improved. This paper forms part of the study 'Variations in self-harm service delivery: an observational study examining outcomes and temporal trends'.

Abstract
We previously described a communication strategy for the delivery of the diagnosis of psychogenic non-epileptic seizures (PNES) that was acceptable and effective at communicating the psychological cause of PNES. This prospective multicenter study describes the short-term seizure and psychosocial outcomes after the communication of the diagnosis and with no additional treatment. Participants completed self-report measures at baseline, two and six months after the diagnosis (seizure frequency, HRQoL, health care utilization, activity levels, symptom attributions and levels of functioning). Thirty-six participants completed the self-report questionnaires. A further eight provided seizure frequency data. After six months, the median seizure frequency had dropped from 10 to 7.5 per month (p=0.9), 7/44 participants (16%) were seizure-free, and an additional 10/44 (23%) showed greater than 50% improvement in seizure frequency. Baseline questionnaire measures demonstrated high levels of impairment, which had not improved at follow-up. The lack of change in self-report measures illustrates the need for further interventions in this patient group.

Abstract
The pathogenesis of chronic enteropathies in dogs likely involves an interaction between the intestinal immune system and luminal intestinal bacteria. German shepherd dogs (GSD) are particularly predisposed to chronic enteropathies. The present study sought to evaluate expression patterns of certain pattern recognition receptors of the innate immunity (Toll-like receptors, TLR), clinical disease activity and histopathological severity in GSD with chronic enteropathies. Mucosal biopsies were collected from the duodenum, colon and ileum of 13 affected GSD and 10 healthy greyhounds as controls. Dogs were objectively assessed using published scoring systems for clinical and histological severity of disease. Diversity of the duodenal microbiota was assessed by construction of 16S rRNA gene libraries. Expression of TLR2, TLR4, TLR5 and TLR9 in biopsies of the duodenum, ileum and colon was assessed by quantitative real-time PCR. TLR4 expression was increased in all intestinal segments in GSD, however, TLR5 expression was very low compared to the healthy dogs. The microbiota in the duodenum of GSDs was significantly different to that of the greyhounds, with an over-representation of 16S rRNA gene sequences belonging to the classes of Bacilli, and Erysipelotrichi, and to the orders of Lactobacillales, Actinomycetales and Erysipelotrichales. These findings could point to a distinct pathogenesis of chronic enteropathies in GSD, with differentially high and low expression of TLR4 and TLR5, respectively, and increased proportions of specific members of the Lactobacillales potentially playing a role.

Abstract
BACKGROUND Research shows that stroke patients and their families are dissatisfied with the information provided and have a poor understanding of stroke and associated issues. OBJECTIVES To assess the effectiveness of information provision strategies in improving the outcome for stroke patients and/or their identified caregivers. SEARCH STRATEGY We searched the Cochrane Stroke Group Trials Register (last searched May 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2007), MEDLINE (1966 to March 2007), EMBASE (1980 to March 2007), CINAHL (1982 to March 2007), PsycINFO (1974 to March 2007), Science Citation Index and Social Science Citation Index (1981 to March 2007), Assia (1987 to March 2007), Index to UK theses (1970 to March 2007), Dissertation Abstracts (1961 to March 2007), ongoing trials and research registers, bibliographies of retrieved papers, relevant articles and books, and the Journal of Advanced Nursing. We also contacted researchers for additional information. SELECTION CRITERIA Randomised trials involving patients or carers of patients with a clinical diagnosis of stroke or transient ischaemic attack (TIA) where an information intervention was compared with standard care, or where information and another therapy were compared with the other therapy alone. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial eligibility and methodological quality and extracted data. Primary outcomes were knowledge about stroke and stroke services, and impact on mood. MAIN RESULTS Seventeen trials involving 1773 patient and 1058 carer participants were included. Eight evaluated a passive and nine an active information intervention. Meta-analyses showed a significant effect in favour of the intervention on patient and carer knowledge, one aspect of patient satisfaction, and patient depression scores. There was no significant effect on number of cases of anxiety or depression in patients, carer mood or satisfaction, or death. Qualitative analyses found no strong evidence of an effect on other outcomes. Post-hoc subgroup analyses showed that active information had a significantly greater effect than passive information on patient mood but not on other outcomes. AUTHORS' CONCLUSIONS There is evidence that information improves patient and carer knowledge of stroke, aspects of patient satisfaction, and reduces patient depression scores. However, the reduction in depression scores was small and probably clinically insignificant. Although the best way to provide information is still unclear there is some evidence that strategies that actively involve patients and carers and include planned follow up for clarification and reinforcement have a greater effect on patient mood.

Abstract
Anal furunculosis (AF) is a chronic, progressive inflammatory disease of the perianal tissues most frequently affecting middle-aged or older German Shepherd dogs (GSD). Because this breed accounts for over 80% of all reported cases, there is likely to be a genetic association with disease susceptibility. Although there are some similarities with perianal fistulation that occurs in human Crohn's disease, the aetiology and pathogenesis of AF are still poorly understood. Recent research has suggested an immune-mediated aetiology, and evidence for this has been further provided by clinical responses to the immunosuppressive drug cyclosporin. The aim of the current study was to investigate canine major histocompatibility complex immune response genes. Dog leucocyte antigen class II alleles and haplotypes were characterised by sequence-based typing of 107 GSD affected with AF and 196 breed-matched controls collected in the UK. A highly significant association of DLA-DRB1*00101 with the presence of AF was observed (OR = 5.01, CI = 2.7-9.3, P < 0.00000001). This association was confirmed in a second cohort of GSD collected in Finland. Homozygosity for this allele is associated with an earlier disease onset.

Abstract
BACKGROUND Growth in antidepressant prescribing is a well-recognised phenomenon in developed countries. In stroke care, the evidence of effectiveness from systematic reviews is surprisingly weak. We therefore decided to undertake a randomised controlled trial comparing fluoxetine to placebo. METHODS Double blind placebo-controlled trial. Cases were high-scorers on the GHQ-28 and we applied minimal exclusion criteria. RESULTS Despite screening 614 patients we were able to randomise only one into the trial. High rates of refusal to participate and exclusions due to physical ill health were coupled with high rates of prescribing among stroke clinicians, to cause this recruitment problem. CONCLUSIONS In addition to the predicted practical problems of conducting an RCT in an elderly frail population, it became clear that most clinicians are not in equipoise about the value of antidepressant medication despite the lack of strong evidence for its effectiveness.

Abstract
BACKGROUND Conversion disorder is an alteration or loss of physical functioning suggestive of a physical disorder that is thought to be due to a psychological stressor or conflict. The fact that many theories about the cause of conversion disorder focus on psychological and social factors would suggest that a psychosocial intervention might be of most benefit. OBJECTIVES To investigate the efficacy of psychosocial interventions on people diagnosed with conversion disorder compared with standard care, a biological intervention or another psychosocial intervention. SEARCH STRATEGY We searched the Cochrane Depression, Anxiety and Neurosis Group Trials Register (May 2004), various databases on OVID (February 2004), handsearched reference lists and textbooks on conversion disorder and contacted relevant authors. SELECTION CRITERIA We included all randomised controlled trials that compared psychosocial interventions for conversion disorder with standard care or other interventions (biological or psychosocial). DATA COLLECTION AND ANALYSIS We reliably selected, quality assessed and extracted data from the studies. For dichotomous outcomes we calculated a relative risk with its associated 95% confidence interval and a number needed to treat. For continuous data we calculated a weighted mean difference. MAIN RESULTS The search identified 260 references, 217 were clearly not relevant to this review and excluded on the basis of their titles and abstracts, 40 more were excluded after reading the full papers (the reasons are given in the excluded studies tables) and only three studies (total n =119) met the inclusion criteria. One study was concerned with paradoxical injunction therapy and the other two studied the value of hypnosis. The three studies had different interventions and control groups so the results could not be combined. All of the studies were of poor methodological quality and it is therefore difficult to place much value on the results of the studies. We were unable to include some data because of poor reporting. AUTHORS' CONCLUSIONS Randomised studies are possible in this field. The use of psychosocial interventions for conversion disorder requires more research and it is not possible to draw any conclusions about their potential benefits or harms from the included studies.

Abstract
Many cancer patients are anxious even when disease is in remission. Anxiety about health, ‘health anxiety’, has distinct features, notably seeking medical reassurance about symptoms. Doctors may then communicate that these symptoms are not due to serious illness, a process known as ‘reassurance’. However, reassurance may inadvertently perpetuate some patients' anxiety. We aimed to observe the relation between symptoms, anxiety and reassurance in consultations with cancer patients. A total of 95 outpatients, with breast or testicular cancers in remission, completed questionnaires measuring health anxiety at study entry, then general anxiety – before a consultation, immediately afterwards, 1 week later, and before their next consultation. We examined symptoms reported and reassurance by oncologists from audio recordings of consultations, and the outcome of subjects' anxiety. The results showed that substantial health anxiety was reported by one-third of the patients. Patients with higher levels of health anxiety reported more symptoms during consultations. Reassurance was ubiquitous, but not followed by an enduring improvement in anxiety. Certain forms of reassurance predicted increased anxiety over time, particularly for subjects who were most anxious. In conclusion, health anxiety can be a problem after cancer. Reassurance may not reduce patients' anxiety. Some reassurance was counterproductive for the most anxious patients. Oncologists may need to use reassurance as a procedure, balancing risk, and benefits, and patient selection and to manage cancer patients in remission.

Abstract
We have previously reported on a model of lipopolysaccharide (LPS)-induced pulmonary inflammation in rats, where LPS-challenged animals develop a significant pulmonary neutrophilia and mucus hypersecretion. In the current studies, we utilized whole body plethysmography and computer assisted data acquisition to examine changes in pulmonary parameters, e.g. frequency (f) tidal volume and Penh as a measure of bronchoconstriction, due to LPS-challenge in conscious rats. Compared to saline challenge, LPS-challenged rats displayed a significant increase in (f) which began within 30 min, peaked by 2 h and remained elevated up to 24 h. Mirroring this increase in (f) was a decrease in the observed tidal volume of LPS-challenged rats. Additionally, compared to saline challenge, LPS-challenge provoked a significant and spontaneous bronchoconstriction, as measured by Penh, 2 h after challenge. In order to further understand these observed LPS-induced pulmonary changes, we utilized two classes of pulmonary obstructive disease standards, namely, bronchodilators and anti-inflammatory agents, and examined their ability to affect the spontaneous bronchoconstriction and the increase in (f) seen at two discrete time points, i.e. 2 and 24 h after LPS-challenge. While ineffective on either the 2 h increase in (f) or the LPS-induced inflammation, animals pretreated with salbutamol (10 mg/kg, p.o.) were protected from the increase in (f) seen at the 24 h time point after LPS-challenge. In contrast, when animals were pretreated with theophylline (10 mg/kg, p.o.) no effect on the LPS-induced pulmonary inflammation or increase in (f) was noted. Meanwhile, in animals pretreated with either betamethasone (3 mg/kg, p.o.) or SB207499 (10 mg/kg, p.o.), a PDE4 inhibitor, doses previously shown to block the LPS-induced neutrophilic inflammation, the persistent increase in (f) seen at 24 h was attenuated, but neither compound was able to attenuate either the increase in (f) or the spontaneous bronchoconstriction seen at 2 h. In summary, the intra-tracheal LPS-challenge of rats results in pulmonary inflammation and dysfunction, which is similar to that seen in COPD patients. We conclude that the early increase in (f) and bronchoconstriction are not dependent upon airway inflammation, but airway inflammation most likely contributes to the persistent increase in (f) seen at 24 h.

Abstract
A screening programme designed to identify cases of Major Depressive Disorder (MDD) in patients attending a Regional Cancer Centre outpatient department was established. It comprised two stages: (1) The Hospital Anxiety and Depression Scale (HADS) self-rating questionnaire administered by a touch-screen computer; (2) we interviewed patients with high scores on the HADS (15 or more total score) over the telephone using the depression section of the Structured Clinical Interview for DSMIV (SCID). A large consecutive sample (5613) of oncology clinic attenders was screened, and practical difficulties in the screening process were identified. The estimated prevalence of major depressive disorder (MDD) in the sample surveyed was approximately 8% (7.8%; 95% confidence intervals 6.9–8.5%). We assessed a consecutive series of 150 patients identified as having MDD to determine how many had received evidence-based treatment for MDD. Only half had discussed their low mood with their general practitioner, only one-third had been prescribed any antidepressant medication, and very few had taken a therapeutic dose for an adequate period. Very few had received psychological treatment or had been referred to mental health services. Most were receiving no potentially effective therapy.

Abstract
The pattern of expression of cytokine mRNA in the lesions of anal furunculosis was evaluated in tissue biopsies from 15 dogs, and compared with the pattern in control skin samples from 24 dogs, by reverse-transcriptase PCR using canine cytokine-specific primers and a semi-quantitative multiplex PCR assay. Interleukin-2 (IL-2) was detected in 11 of the 15 affected dogs but in only one of the controls, and interferon-gamma was detected in 14 of the affected dogs but none of the controls. In contrast, IL-4 was detected only in one of the affected dogs. Increased expression of mRNA for IL-1beta, IL-6, tumour necrosis factor alpha, IL-8, IL-10 and transforming growth factor beta1 was detected in the biopsies from the lesions of anal furunculosis relative to the control tissues (P < 0.05).

Abstract
The choice of initial immunosuppressive therapy (IST) following solid organ transplant remains a source of some controversy. Cyclosporine A (CsA) has been the basis of most IST protocols over the past two decades but has recently been supplanted in many centers by the use of tacrolimus (TAC)-based protocols. Renal allograft recipients in London may receive either CsA or TAC based IST, along with prednisone and azathioprine or (since 1999) mycophenolate mofetil (MMF). The decision is based on criteria such as age, gender, diabetic status, and lipid levels, which are felt to be impacted by the delivery of CsA or TAC based IST. The present analysis focuses on the results of BP and renal function in renal transplant patients receiving CsA or TAC based initial therapy during the period January 1, 1996 to June 30, 2002. Patients receiving TAC based IST were significantly younger than those receiving CsA (44 +/- 13.9 vs 50.5 +/- 12.3 years; P < .004). Mean arterial pressure (MAP) was lower in the TAC patients at 1 month (97.8 +/- 13.1 vs 103.2 +/- 11.8 mm Hg; P = .035), but became equivalent to CsA-treated patients for the balance of the follow-up period of up to 60 m. Serum creatinine was not significantly different between groups at any time during up to 60 months of follow-up. Based on these results, it seems apparent that the choice of calcineurin inhibitor may not influence renal function or blood pressure in long-term renal allograft survivors.

Abstract
Chronic allograft nephropathy (CAN) remains a significant cause of late renal allograft loss. Although many factors may be involved in pathogenesis, the hemodynamic and fibrogenic consequences of long-term therapy with cyclosporine (CsA) have been implicated as important potentially reversible causes. CsA's effect on CAN is mediated in part through increased renal expression of TGF-beta, which can be modified by administration of angiotensin receptor blockers (ARBs). A pilot study was undertaken to evaluate the safety and efficacy of the ARB valsartan on renal function and proteinuira in patients with CAN. Ten patients on CsA-based therapy with evidence of CAN received valsartan in an initial dose of 80 mg/d, force titrated to 160 mg/d after 4 weeks, for a total of 52 weeks. Renal function was evaluated by serum creatinine, 24-hour creatinine clearance (CrCl), and isotope, GFR and urinary protein by 24-hour protein excretion. The 10 patients were aged 20 to 71 years and had been transplanted for 88.2 +/- 64.8 months at the time of study. After 52 weeks of valsartan therapy mean blood pressure (BP) fell from 152/88 mm Hg to 138/77 mm Hg (P =.06); serum creatinine rose from 206 +/- 55 micromol/L to 238 +/- 81 micromol/L (P =.22.); GFR fell from 39.8 +/- 17.6 to 31.9 +/- 19 mL/min (P =.23); and urine protein fell from 2.16 +/- 2.7 to 1.12 +/-.095 g/24 hours (P =.13). Side effects of valsartan therapy were few and included transient hyperkalemia in 2/10 patients. The small rise in serum creatinine and fall in GFR observed were not statistically significant. Urine protein fell by more than 50%, though the small patient numbers in this pilot study prevent this from achieving statistical significance. It is concluded that valasartan reduces BP and proteinuria in CAN patients without inducing a serious worsening in renal function. Valsartan may have a role to play in the management of patients with CAN.

Abstract
PURPOSE We aimed to estimate the prevalence and types of anxiety disorders diagnosed according to standardized criteria in cancer patients, to compare screening tools in detecting them, and to examine their demographic, oncologic, and psychosocial associations. METHODS In this cross-sectional observational study of 178 subjects with lymphoma, renal cell carcinoma, malignant melanoma, or plasma cell dyscrasia, we related responses to questionnaires (administered by computer touch-screen) measuring psychological symptoms, quality of life (QOL), and social support to standardized psychiatric interviews and cancer management. RESULTS Forty-eight percent of subjects reported sufficient anxiety for anxiety disorder to be considered. At subsequent diagnostic interview, 18% fulfilled International Classification of Disorders, 10th Revision criteria for anxiety disorder, including 6% of patients who reported low levels of anxiety by questionnaire. When subjects reported anxiety by questionnaire, if disruptive somatic anxiety was present, this increased the probability of diagnosable anxiety disorder from.31 to.7. The most accurate screening questionnaires were the trait scale of the State-Trait Anxiety Inventory and the Hospital Anxiety and Depression scale. Female sex and negative aspects of social support were associated with anxiety disorder in multivariate analyses. Anxiety disorder was independently associated with a deficit in QOL, particularly insomnia. CONCLUSION Anxiety symptoms are common in cancer patients. Screening by questionnaire seems to assess anxiety symptoms adequately but discriminates abnormal anxiety inadequately. To improve this, we may need to use criteria such as disruption from anxiety, as illustrated by the impact of anxiety disorders on QOL. There seem to be few oncologic variables that could target screening for anxiety disorders.

Abstract
Development of effective treatments for patients following deliberate self-harm (self-poisoning or self-injury) is a very important element in suicide prevention. The randomized controlled trial (RCT) is the mainstay of evaluation of treatments. In a systematic review of the literature, the effectiveness of treatments based on RCTs was examined and the quality of the RCTs was assessed. Twenty trials were identified, and where possible, these were grouped on the basis of similarities among the types of treatment. In this paper, we examine the methodological aspects of the trials and consider what may be learned that will assist in the design of future studies in this field. The methodological quality of the trials was reasonable, but most trials included too few participants to detect clinically important differences in rates of repeated self-harm. In planning future trials, the following major issues should be addressed: investigators should perform power calculations to determine the number of subjects necessary to detect clinically important effects, provide information on method of randomization and interventions, use standard measures of outcome, and focus on homogeneous subgroups of patients. Improving the methodology of future studies in this field will be essential if sound evidence is to be obtained which can inform effective service provision for deliberate self-harm patients.

Abstract
The aim of the study was to confirm the validity of using touchscreen computers for screening for clinically significant levels of distress among cancer patients in routine oncology practice. The Hospital Anxiety and Depression Scale (HADS), EORTC Quality of Life questionnaire (QLQ-C30), Mental Health Inventory-MHI5 and a Concerns Checklist were administered via touchscreen computer to 172 chemotherapy out-patients, twice, 2-4 weeks apart. A standard psychiatric interview (Present State Examination - PSE) was conducted within a week of the second assessment. On interview, 23% of patients were identified as 'cases'. Using the available data (questionnaires, sociodemographic details, self-reported past psychiatric history), the best screening strategy combined scores from MHI-5 and HADS from a single time-point with the following rules: if MHI-5 < 11 = non-case; if MHI-5 > or = 11 then use HADS; then, if HADS > or = 9 = 'case' (sensitivity 85%; specificity 71%; misclassification rate 26%; positive predictive value 47%). The computerized screening system enabled data to be collected, scored, collated and reported in real time to identify patients who warrant further clinical assessment. It offers the potential for improving 'case' detection in routine oncology practice while reducing the burden of questions put to 'non-cases'. Further work is needed to develop optimal choice of screening questions for this purpose.

Abstract
BACKGROUND Brief problem-solving therapy is regarded as a pragmatic treatment for deliberate self-harm (DSH) patients. A recent meta-analysis of randomized controlled trials (RCTs) evaluating this approach indicated a trend towards reduced repetition of DSH but the pooled odds ratio was not statistically significant. We have now examined other important outcomes using this procedure, namely depression, hopelessness and improvement in problems. METHOD Six trials in which problem-solving therapy was compared with control treatment were identified from an extensive literature review of RCTs of treatments for DSH patients. Data concerning depression, hopelessness and improvement in problems were extracted. Where relevant statistical data (e.g. standard deviations) were missing these were imputed using various statistical methods. Results were pooled using meta-analytical procedures. RESULTS At follow-up, patients who were offered problem-solving therapy had significantly greater improvement in scores for depression (standardized mean difference = -0.36; 95% CI -0.61 to -0.11) and hopelessness (weighted mean difference =-3.2; 95% CI -4.0 to -2.41), and significantly more reported improvement in their problems (odds ratio = 2.31; 95% CI 1.29 to 4.13), than patients who were in the control treatment groups. CONCLUSIONS Problem-solving therapy for DSH patients appears to produce better results than control treatment with regard to improvement in depression, hopelessness and problems. It is desirable that this finding is confirmed in a large trial, which will also allow adequate testing of the impact of this treatment on repetition of DSH.

Abstract
INTRODUCTION This study describes a method to measure the cough reflex in dogs that is simple to perform, requires no surgical intervention and can be used to profile efficacy and side-effect liabilities of antitussive drugs. METHODS Experiments were performed in propofol-anesthetized dogs in which cardiopulmonary functions were non-invasively monitored before and after the induction of cough produced by spraying 0.75 ml of distilled water into the trachea. RESULTS The magnitude of the cough response, measured by the frequency and amplitude was not different for individual dogs performed with repeated trials on different days. Treatment with the opioid antitussive drug, torbutrol (0.055-0.0055 mg/kg, s.c.) inhibited the cough frequency but not the amplitude induced by the water challenge. Furthermore, side effects of torbutrol were identified as mild respiratory depression and an anesthetic-sparing effect with propofol. DISCUSSION This method offers many distinct advantages to evaluate efficacy of antitussive drugs including the fact that no surgery is required, it takes only 15-20 min to complete an experiment, and it can be used to simultaneously profile antitussive and side effect liabilities of drugs developed for the treatment of cough.

Abstract
BACKGROUND Somatoform disorders have few peers in terms of personal morbidity and cost to the health service, yet many psychiatrists train without any experience of them. AIMS To review the prevalence, disability and economic burden of somatoform disorders, and to explore the reasons why they are neglected by psychiatrists. METHOD A selective review of the key literature. RESULTS Psychiatrists' current preoccupation with so-called 'serious mental illness' gives somatoform disorders low priority. Some health planners have erroneously equated severity with diagnosis rather than level of need and disability. As a consequence the development of psychiatric services has been neglected. CONCLUSIONS Greater recognition of the importance of somatoform disorders will only occur if high quality research and teaching receive priority, and if the Royal Colleges continue to press for increasing public awareness of their importance. Services should be driven by clinical need rather than diagnosis.

Abstract
Airway hyperresponsiveness to neurokinin A (NKA) occurs in inflammatory airway diseases like asthma. In this study, bronchoconstrictor reactivity to NKA was measured in beagle dogs neonatally sensitized to and challenged with ragweed. Comparisons were made to histamine and methacholine. Lung resistance (R(L)) and dynamic lung compliance (C(Dyn)) were measured in anesthetized, spontaneously breathing dogs before and after aerosol challenge with NKA, histamine or methacholine. The concentration of these agents increasing R(L)by 25% above baseline (PC(25)) was calculated before and 24 h after aerosolized ragweed challenge. Before ragweed, the bronchoconstrictor reactivity to NKA was four-fold higher in ragweed-sensitized dogs (PC(25)=0.036+/-0.006%) compared to non-sensitized controls (PC(25)=0.177+/-0.030%, P<0.05). On the other hand, there was no difference in the bronchoconstrictor reactivity to histamine or methacholine between these two groups. Twenty-four hours after ragweed challenge to sensitized dogs, NKA reactivity was unchanged from pre-ragweed values but histamine and methacholine reactivity was increased by 2-3-fold. These results demonstrate airway hyperresponsiveness to NKA, histamine and methacholine in allergic beagle dogs although hyperresponsiveness to NKA exists in these allergic dogs before an antigen challenge. This animal model may prove to be useful to evaluate the role of tachykinins in hyperractive airway diseases.

Abstract
Tachykinins have been implicated as important mediators of asthma. This study used neurokinin A (NKA) and substance P (SP) to evaluate the effect of tachykinins on airway mechanics in cynomolgus monkeys. NK(1)-(CP 99,994) and NK(2)-(SR 48968) receptor antagonists were used to evaluate the role of NK(1)and NK(2)receptors on responses to NKA and SP. Lung resistance (R(L)) and dynamic lung compliance (C(Dyn)) were measured in anesthetized, mechanically ventilated cynomolgus monkeys following aerosol or intravenous challenge with NKA, SP or the standard bronchoconstrictor, histamine. Inhaled NKA or SP had variable effects on R(L)and C(Dyn)whereas aerosolized histamine (0.01-1 mg/ml) dose-dependently increased R(L)and decreased C(Dyn). Intravenous NKA (1-100 microg/kg), SP (1-30 microg/kg) or histamine (1-100 microg/kg) increased R(L)and decreased C(Dyn). Pretreatment with SR 48968 (0.1 and 1 mg/kg, i.v.) blocked bronchoconstrictor responses to i.v. NKA, whereas CP 99,994 (0.1 and 1 mg/kg, i.v.) was without effect. Bronchoconstrictor responses to i.v. SP were partially blocked by SR 48968 and CP 99,994. In conclusion, both NKA and SP produce bronchonconstriction in cynomolgus monkeys and this effect is more pronounced when they are given by the iv route. Furthermore, both NK(1)and NK(2)receptors are involved in the bronchonconstrictor response to exogenously administered tachykinins in cynomolgus monkeys.

Abstract
We investigated the kinds of instructional and assessment accommodations students with disabilities receive, and the extent to which instructional accommodations match assessment accommodations. Most students who had IEPs in specific content areas received instructional accommodations in those areas, and there were no differences by disability type. We provide data on the specific types of accommodations used. Overall, students' assessment accommodations matched their instructional accommodations, though many students received testing accommodations that had not been received in instruction. Implications are discussed for IEP teams who make decisions about instructional and assessment accommodations.

Abstract
People with dementia or delirium have increased mortality in the 6 months after hip fracture, but depression might take longer to have an effect. We assessed the psychiatric status of 731 participants with hip fracture and analysed the effect of psychiatric illness on mortality during the next 2 years. We found that dementia, delirium, and depression all increased the risk of mortality (p<0.0001, p<0.0001, and p=0.0359, respectively), and that mortality differed significantly between hospitals (p=0.0003). We suggest that psychiatric interventions should be asssessed in hip-fracture patients with adequate follow up of outcome measures.
