Abstract
BACKGROUND People who inject drugs are disproportionately affected by HIV and hepatitis C virus (HCV) infections, while there is little global data on HIV and HCV testing and treatment coverage of this population. We conducted a systematic review to evaluate country-level, regional, and global coverage of HIV and HCV testing and treatment among people who inject drugs. METHODS We did a systematic review, and searched bibliographic databases (MEDLINE, Embase, and PsycINFO) and grey literature for studies published between Jan 1, 2017, and April 30, 2022, that evaluated the proportion of people who inject drugs who received testing or treatment for HIV or HCV. For each country, we estimated the proportion of people who inject drugs tested for HIV antibodies in the past 12 months (recent), people who inject drugs ever tested for HCV antibodies and HCV RNA, people who inject drugs with HIV currently receiving antiretroviral therapy, and people who inject drugs with HCV ever receiving HCV antiviral treatment. Regional and global estimates, weighted by the population size of people who inject drugs, were generated where sufficient data were available. This study is registered with PROSPERO (CRD42020173974). FINDINGS 512 documents reported data eligible for analyses, including 337 peer-reviewed articles, 27 conference abstracts or presentations, and 148 documents from grey literature or supplementary searches. Data of recent HIV antibody testing were available for 67 countries and ever having had HCV antibody testing were available for 49 countries. Globally, an estimated 48·8% of people who inject drugs were recently tested for HIV antibodies (95% uncertainty interval [UI] 43·3-54·2%; range 0·9-86·0%), and 47·1% had ever been tested for HCV antibodies (95% UI 43·4-51·0%; range 0·0-93·3%). HCV RNA testing data were available from three countries. Coverage of HIV antibody testing was high (>75%) in four countries and for HCV antibody testing in 15 countries. The estimated uptake of current HIV treatment (18 countries) ranged from 2·6% to 81·9%, and the estimated uptake of ever having HCV treatment (23 countries) ranged from 1·8% to 88·6% across countries. Uptake of HIV treatment was high in two countries, and of HCV treatment in one country. INTERPRETATION HIV and HCV testing and treatment uptake among people who inject drugs was highly variable, and suboptimal in most countries. Strategies to improve access to HIV and HCV care among people who inject drugs and the availability of public health surveillance are urgently required.

Abstract
BACKGROUND People who inject drugs are exposed to various and changing risk environments and are at risk of multiple harms related to injecting drug use (IDU). We aimed to undertake a global systematic review of the prevalence of IDU, key IDU-related harms (including HIV, hepatitis C virus [HCV], and hepatitis B virus [HBV] infection and overdose), and key sociodemographic characteristics and risk exposures for people who inject drugs. METHODS We systematically searched for data published between Jan 1, 2017, and March 31, 2022, in databases of peer-reviewed literature (MEDLINE, Embase, and PsycINFO) and grey literature as well as various agency or organisational websites, and disseminated data requests to international experts and agencies. We searched for data on the prevalence, characteristics, and risks of people who inject drugs, including gender, age, sexuality, drug-use patterns, HIV, HCV, and HBV infections, non-fatal overdose, depression, anxiety, and injecting-related disease. Additional data were extracted from studies identified in our previous review. Meta-analyses were used to pool the data where multiple estimates were available for a country. We present country, regional, and global estimates for each variable examined. FINDINGS We screened 40 427 reports published between 2017 and 2022, and the 871 eligible reports identified were added to the 1147 documents from the previous review. Evidence of IDU was documented in 190 of 207 countries and territories, and 14·8 million people (95% uncertainty interval [UI] 10·0-21·7) aged 15-64 years globally were estimated to inject drugs. Existing evidence suggests that there might be 2·8 million (95% UI 2·4-3·2) women and 12·1 million (95% UI 11·0-13·3) men who inject drugs globally, and that 0·4% (95% CI 0·3-1·3) of people who inject drugs identify as transgender. The amount of available data on key health and social risks among people who inject drugs varied widely across countries and regions. We estimated that 24·8% (95% CI 19·5-31·6) of people who inject drugs globally had experienced recent homelessness or unstable housing, 58·4% (95% CI 52·0-64·8) had a lifetime history of incarceration, and 14·9% (95% CI 8·1-24·3) had recently engaged in sex work, with substantial geographical variation. Injecting and sexual risk behaviour varied considerably geographically, as did risks of harms. Globally, we estimated that 15·2% (95% CI 10·3-20·9) of people who inject drugs are living with HIV, 38·8% (95% CI 31·4-46·9) have current HCV infection, 18·5% (95% CI 13·9-24·1) have recently overdosed, and 31·7% (95% CI 23·6-40·5) have had a recent skin or soft tissue infection. INTERPRETATION IDU is being identified in a growing number of countries and territories that comprise more than 99% of the global population. IDU-related health harms are common, and people who inject drugs continue to be exposed to multiple adverse risk environments. However, quantification of many of these exposure and harms is inadequate and must be improved to allow for better targeting of harm-reduction interventions for these risks.

Abstract
Although the equine sarcoid is the most common skin neoplasm in domesticated horses, histopathological characteristics have not previously been evaluated for association with recurrence. The aim of this retrospective cohort study was to investigate clinical and histopathological features of excised equine sarcoids and to evaluate their association with recurrence at the original surgical site and at new sites. Clinical records and excisional biopsies from 106 equine sarcoids from 64 horses referred to Leahurst Equine Hospital, University of Liverpool, between March 2010 and February 2015 were retrieved. Biopsies were re-evaluated histologically. Clinical data were obtained from hospital records, and owner-reported follow-up data were obtained by telephone questionnaire. Associations between clinical and histopathological features of sarcoids and their recurrence at the surgical site were determined using uni- and multivariable mixed effects logistic regression. Recurrence of sarcoids at the surgical site occurred in 30 horses (46.9%). Sarcoids developed at a distant site in 21 horses (32.8%). In the final mixed effects logistic regression model, only superficial inflammation was associated with reduced odds of recurrence at the surgical site (adjusted odds ratio, 0.32; 95% confidence intervals, 0.10-0.96; P = 0.04). This suggests that the inflammatory process may play a role in protecting horses against the recurrence of sarcoids.

Abstract
The causes of the inherently high variation in number of follicles and oocytes in ovaries of mammals are unknown. Evidence suggests that the ovarian reserve (total number of healthy follicles and oocytes in ovaries) can be programmed by events occurring during fetal life. For instance, maternal nutritional restriction during the first trimester of pregnancy negatively affects the size of the ovarian reserve in calves. The aim of the present study was to establish whether exposure of pregnant dairy cows to high environmental temperatures from conception to the end of the first trimester of pregnancy impairs establishment of the ovarian reserve in their offspring. This work was conducted in four commercial dairy farms with similar nutrition and farming systems located in Sardinia, Italy, on a total of 310 Holstein-Friesian dairy heifers (16 months old) that were conceived and born at different times of year coincident with different environmental temperatures. We tested whether exposure of the heifer's dams to a mean temperature-humidity index (THI) >68 from conception to the end of the first trimester of pregnancy resulted in a diminished ovarian reserve in their offspring. To estimate the size of the ovarian reserve, a single blood sample was collected to measure serum anti-Müllerian hormone (AMH; n=310), and the number of follicles >3mm (antral follicle count, AFC) was assessed using transrectal ovarian ultrasonography (n=258) on a random day of the oestrous cycle (16.09±0.07 months of age). Relations among variables were analysed with Pearson correlation with SAS (SAS Institute Inc.). Anti-Müllerian hormone and AFC were analysed with a mixed model (PROC MIXED of SAS) considering the main effects of season during the first trimester of fetal life and age at sampling; the effect of farm was included as a random effect. Tukey's test was used for comparisons. Circulating AMH concentrations and AFC were highly positively correlated (P<0.0001), as previously reported. The results also showed that both AMH concentrations and AFC were lower (419.27±22.81 pgmL−1, 9.32±0.42 follicles; P<0.0001) in young adult heifers of the dams exposed to a THI >68 compared with dams exposed to an average THI of 55 (634.91±47.60 pgmL−1, 11.84±0.46 follicles). Neither AMH nor AFC were influenced by farm and age at sampling of the daughters. In conclusion, maternal exposure to THI >68 (typical high temperatures during summers in Sardinia) during the first trimester of pregnancy has a negative effect on the development of the ovarian reserve in female fetuses, which may subsequently impair their reproductive performance as adults.

Abstract
Published information on the pharmacokinetic and pharmacodynamic properties of pergolide is limited. The aim of this study was to investigate the pharmacokinetic and pharmacodynamic properties of oral pergolide in horses with pituitary pars intermedia dysfunction (PPID). The study design was a nonrandomized clinical trial. Six horses with PPID diagnosed by thyrotropin-releasing hormone (TRH) stimulation tests received pergolide at 4 μg/kg for 18 d. Plasma samples for determination of pergolide and ACTH concentration were collected 0.5 h before and 2 and 12 h after each administration of pergolide. Maximum plasma concentrations after the first oral dose of pergolide (0.104-0.684 ng/mL; median 0.261 ng/mL; interquartile range [IQR] 0.184-0.416 ng/mL) were not significantly different to the maximum steady-state concentration at day 18 (0.197-0.628 ng/mL; median 0.274; IQR 0.232-0.458 ng/mL). Chronic administration was not associated with drug accumulation (R = 1.09) and pergolide concentration reached steady state within 3 d. Throughout, concentrations of pergolide fluctuated considerably, with median plasma peak concentrations more than four times higher than median trough concentrations. Plasma ACTH concentration reduced significantly within 12 h of administration with further reductions occurring up to 10 d after the initiation of treatment. Although there were parallel fluctuations in the concentrations of pergolide and ACTH, timing of ACTH measurement in relation to the administration of pergolide did not have a significant effect. Alterations in the response to TRH were identified at 8 d with no further change being identified at 18 d. A small number of horses were studied. Oral pergolide results in significant suppression of pars intermedia activity within hours. Pergolide and ACTH concentrations fluctuated in tandem although correlation was poor. Fluctuations in pergolide concentration were consistent with a terminal elimination half-life of less than 12 h. To reduce the level of fluctuation of ACTH, twice-daily dosing of pergolide may be more appropriate.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

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
OBJECTIVES To evaluate the effect of syringe size, needle size, number of needle passes and operator experience on cell yield from tumour fine-needle aspirates, and the quantity and quality of extractable RNA. MATERIALS AND METHODS Fine-needle aspirates were collected from canine lymphoma, cutaneous mast cell tumour, anal gland adenocarcinoma, fibrosarcoma and oral malignant melanoma using nine different techniques. RESULTS There was a significant difference in cell yield between fine-needle aspirate techniques for melanoma, lymphoma and anal gland adenocarcinoma. The application of suction yielded the largest number of cells. Cell numbers in lymphoma and fibrosarcoma aspirates collected by different veterinary surgeons were not significantly different. Use of a smaller gauge needle and suction increased the quantity of RNA isolated from fibrosarcoma and anal gland adenocarcinoma aspirates, but did not influence RNA integrity. CLINICAL SIGNIFICANCE Suction during fine-needle aspiration increases cell numbers obtained from five common canine tumours. Suction increases the quantity of RNA isolated from anal gland adenocarcinoma and fibrosarcoma aspirates without affecting RNA quality. Junior veterinary surgeons gain comparable cell numbers to senior staff.

Abstract
Lameness in beef and dairy cattle is responsible for economic losses and has significant animal welfare implications. It has been proposed that early treatment with analgesics not only reduces acute pain but also leads to reduced long-term sensitization. Fifty-three cattle (309–954 kg body weight [BW], mean: 656 kg) with musculoskeletal lameness were scored for lameness and inflammation, then randomly assigned to a single oral treatment with meloxicam oral suspension (MOS) (28 animals) at 1 mg/kg or saline at 1 mL/15 kg BW. Lameness and inflammation were reevaluated 3 days after treatment, and 26 of 28 (92.8%) MOS-treated animals had a reduced lameness score, while only three of 25 control animals had a reduced lameness score. MOS was effective in treating musculoskeletal disease in cattle. In an accompanying residue depletion study, 22 lactating Holstein cows (BW: 553–927 kg, mean: 713 kg) were used in the study. All 22 animals received MOS at the dose of 1 mg/kg BW once. Milk (500 mL sample from the full milking volume) was collected at approximately 48, 72, 96, and 120 hours after the treatment. Samples were subjected to in vitro analysis for quantification of meloxicam by liquid chromatography and mass spectroscopy. The mean meloxicam concentration at 48 and 72 hours were 30.75 and 2.82 ng/mL, respectively. The meloxicam milk concentration was below the limit of quantification (1 ng/mL) in 15 of 22 animals at 96 hours and in 22 of 22 animals at 120 hours. The milk meloxicam levels in all animals were below the maximum residue limit (Canada: 35 ng/mL; Europe: 15 ng/mL) at the 72-hour sampling.

Abstract
Equine herpesvirus type 1 (EHV-1) and type 4 (EHV-4) have a worldwide distribution and cause respiratory disease, abortion, neonatal death and myeloencephalopathy in susceptible horses. Given the scarcity of serological EHV-1/EHV-4 data in Spain, the objective of this cross-sectional study was to estimate the seroprevalence of EHV-1/EHV-4 and to identify potential horse-level and stud farm-level factors associated with EHV-1/EHV-4 in the breeding Spanish Purebred (SP) horse population in central Spain. Serum samples from 334 SP unvaccinated horses, collected between September 2011 and November 2013 at 30 stud farms, were tested using a commercially available EHV-1/EHV-4 antibody ELISA and seroneutralisation as the World Organisation for Animal Health reference confirmation test. Data on factors putatively associated with seropositivity to EHV-1/EHV-4 were collected via a questionnaire and examined using logistic regression analysis. EHV-1/EHV-4 seroprevalence in the SP breeding population in central Spain, standardised for the sex distribution of the reference horse population, was 53.9 per cent (95 per cent confidence interval 44.0 per cent to 63.8 per cent). Increasing age, southern location of the stud farm, temperate climate during the summer, and a smaller surface area used for breeding activities in the farm were associated with increased odds for EHV-1/EHV-4 seropositivity, whereas EHV-1/EHV-4 vaccination of other resident horses and separation of breeding mares from youngsters were protective factors.

Abstract
REASONS FOR PERFORMING STUDY Equine viral arteritis (EVA), a disease caused by infection with the equine arteritis virus (EAV), is present in many European countries. In Spain, the last confirmed outbreak was reported in 1992 and there is a paucity of seroprevalence studies. The disease has a major impact on the equine breeding industry, which is mainly represented by Spanish Purebred (SP) horses in Spain. OBJECTIVES To estimate the seroprevalence of EAV in the breeding SP horse population in central Spain and identify potential horse and studfarm level factors associated with seropositivity to EAV. STUDY DESIGN Cross-sectional study. METHODS Individual serum samples from 555 SP horses, collected between September 2011 and November 2013 at 35 studfarms, were tested using a commercially available EAV antibody ELISA and seroneutralisation as the World Organisation for Animal Health reference confirmation test for samples with positive and equivocal results. Data on factors putatively associated with seropositivity to EAV were collected via a questionnaire and examined using random effects logistic regression for analysis of clustered data. RESULTS Equine arteritis virus seroprevalence in the SP breeding population in central Spain standardised for the sex distribution of the reference horse population, was estimated to be 16.8% (95% confidence interval 5.2-28.5%). Increasing numbers of breeding mares on the studfarm and increasing percentage of mares with reproductive problems during the last 12 months were identified as being positively associated with EAV seropositivity. Mares vaccinated against Equine herpesvirus-1 (EHV-1) and/or -4 (EHV-4) were also positively associated with EAV seropositivity. CONCLUSIONS These findings are of importance to ensure appropriate biosecurity measures for studfarms are carried out and may help facilitate the development of an EVA surveillance programme in the SP breeding horse population.

Abstract
REASONS FOR PERFORMING STUDY There have been no detailed descriptions of the radiological appearance of the centrodistal joint interosseous ligament region in horses with and without distal tarsal joint pain. OBJECTIVES To describe the normal radiological appearance of the centrodistal joint interosseous ligament region; to determine the prevalence of mineralisation or ossification of the interosseous ligament; and to describe radiological abnormalities surrounding the interosseous space and concurrent radiological abnormalities in the tarsus. The association between interosseous ligament region abnormalities and radiological evidence of osteoarthritis of the centrodistal joint was assessed. STUDY DESIGN Retrospective study. METHODS Case records and radiographs of all horses/ponies (n = 700) that underwent radiographic examination of one/both tarsi over 7 years were reviewed. Case history, height, bodyweight and cause(s) of lameness were recorded. Factors associated with abnormalities of the centrodistal interosseous ligament region were assessed using logistic regression analysis. RESULTS The normal interosseous space was an oval or circular-shaped radiolucent area bordered proximally and distally by a rim of bone of uniform opacity and thickness, which varied in thickness among animals. Abnormalities of the interosseous ligament region of the lame(r) limb were evident in 121/700 (17.3%; 95% confidence interval 14.5-20.1%) animals. Increasing bodyweight was associated with decreased odds of interosseous ligament region abnormalities. Forty-seven animals (6.7%; 95% confidence interval 4.9-8.6%) had radiological evidence of osteoarthritis of the centrodistal joint. A greater proportion of animals with interosseous ligament region abnormalities (36.4%) had radiological evidence of osteoarthritis of the centrodistal joint, compared to those with normal interosseous ligament regions (0.5%; P<0.001). Interosseous ligament region abnormalities and osteoarthritis of the centrodistal joint were not necessarily associated with distal tarsal joint pain. CONCLUSIONS There is an association between abnormalities of the centrodistal joint interosseous ligament region and osteoarthritis. Radiological evidence of abnormalities of the centrodistal intertarsal ligament region alone or in association with osteoarthritis may be present asymptomatically.

Abstract
Correlating magnetic resonance (MR) imaging and histopathological findings is essential to validate low field MR imaging in lame horses. This study aimed to compare signal changes in the deep digital flexor tendon (DDFT) of the distal limb on low field MR imaging with macroscopical and histological findings. Cadaver limbs from lame horses with DDFT lesions were selected. The DDFT MR imaging findings and histopathological results were graded, and macroscopical abnormalities were recorded. There was a strong correlation between MR imaging and histopathology grades (rs = 0.76, p < 0.001) in the foot. There was moderate agreement (Kappa statistic 0.52) between the MR and histopathology grades; agreement was superior further proximal in the foot. The presence and severity of pathology in the DDFT are well represented by the presence and severity of MR imaging signal changes. The study supports the use of low field MR imaging for diagnosis of equine distal limb DDFT lesions.

Abstract
On reading the title of an article the reader can sometimes wonder what the author is trying to say, as the title seems so far removed from the research covered in the article. Do such authors forget that many readers of health and medical journals browse the list of contents (in a paper or electronic format) and use titles to select the article that attracts attention? Academic authors are often not clear enough in the titles of their articles, and hence may not attract as large a readership as possible. Any author would want their article to be read and cited, and to stand out in a crowded Table of Contents or a list of papers found in a search on electronic databases.DOI: http://dx.doi.org/10.3126/nje.v4i1.10138 Nepal Journal of Epidemiology 2014;4 (1): 344-347

Abstract
262 Background: Treatment options for pts with BCG-refractory NMITCC are limited and there is no established role for systemic chemotherapy in this setting. While cystectomy remains the gold standard, the vast majority of pts are unable or unwilling to have surgery. Sunitinib is an oral tyrosine kinase inhibitor of VEGFR-2, PDGFR, KIT and FLT3 with demonstrated antitumor activity in advanced TCC. To determine the clinical and biologic effects of sunitinib in BCG-refractory NMITCC pts a prospective phase II study was conducted. Methods: Pts with biopsy proven BCG- refractory NMITCC received three 28-day cycles of continuous sunitinib (37.5 mg PO). Subsequently, pts underwent cystoscopic evaluation. If no tumor was found, pts continued with standard cystoscopic surveillance. A single stage design was employed to test the hypothesis of a 25% improvement in the 12-month CR rate over the 20% CR historically observed in this setting. Overall response rate (ORR), disease-free recurrence (DFR) and safety were recorded. Exploratory endpoints included treatment effect on CTCs, type-1 response and immunosuppressive Treg cells. Results: To date 17 of a planned 31 pts are enrolled. Median age is 72 years (range, 54-82); 94% of pts were ECOG 0; 6 pts had received additional intravesical therapy other than BCG. Fourteen pts have already completed 3 cycles of treatment and 13 pts had at least once cystoscopic assessment. Among these, 8 pts (62%) were NED in their first cystoscopic evaluation. Most common treatment-related toxicity observed in both studies included fatigue, HTN, stomatitis, PPE, diarrhea and thrombocytopenia. Treatment with sunitinib also resulted in a sustained increase (compared to pre-treatment) in CD3+ and CD4+ IFN-g producing T-cells (p < 0.07). In addition there was a significant decrease in CD33+ MDSC following 2 and 3 cycles of therapy (p < 0.04). There was also a significant decrease in T regulatory cells following 2 cycles of therapy (p = 0.04); however it was not maintained during cycle 3 (p = 0.36). Conclusions: Sunitinib has modest clinical activity in pts with BCG-refractory NMITCC. Early immune studies also denote the ability of sunitinib to restore the balance of type-1 and type-2 immune response in bladder cancer. [Table: see text]

Abstract
BACKGROUND Lengthy social separation and prolonged fasting time contribute to increased risks associated with anesthesia in captive primates. This study is an initial attempt to identify a safe pre-anesthetic fasting procedure by identifying gastric emptying time (GET) and gastrointestinal transit time (GTT) of captive chimpanzees, Pan troglodytes. METHODS Seven adult chimpanzees at the North Carolina Zoo immobilized for annual physical examinations were fed barium-impregnated polyethylene spheres to measure GET. Eleven animals were individually fed a color dye marker and fecal passage was observed to determine GTT. RESULTS Gastric emptying time (GET) was approximated to be >3 hours but <16 hours. The mean GTT was 16.5 hours. CONCLUSIONS This study indicates that a fasting time of 3 hours would allow for complete gastric emptying and could potentially replace the current overnight fast (≥16 hour) to help minimize complications associated with pre-anesthetic fasting in captive primates.

Abstract
AbstractThe RNiSb compounds (R=Ho, Er, Tm, Yb and Y) and some selected solid solution members such as (Zr1-xErx)Ni(Sn1-xSbx) and ErNiSb1-xPnx (Pn=As, Sb, Bi) have been studied. They all crystallize in the MgAgAs structure type, which can be considered as a NaCI structure type in which half of the interstitial tetrahedral sites are occupied by Ni atoms. The measured values of the Seebeck coefficients, at room temperature, are positive for RNiSb (R=Ho, Er, Yb and Y) compounds and ErNiSb1-xPnx (Pn=As, Sb, Bi) solid solutions, but for (Zr1-xErx)Ni(Sn1-xSbx) members vary from negative to positive values when 0 < x < 1. Some of these compounds show metallic conductivity while others exhibit thermally activated charge transport. Solid solutions of these materials have lower thermal conductivities than the pure members, RNiSb (R=Ho, Er, Yb and Y) and ZrNiSn. The electronic structures of RNiSb compounds, where R is Y, La, Lu, and Yb, have been studied with density functional theory. The results of the calculations for these systems, except for the Yb compound, indicate narrow gap semiconductors with large effective masses near the conduction band extrema. The Yb system is expected to show heavy fermion characteristics.

Abstract
AbstractThe AgPbBiQ3 class of compounds and their solid solution members are related to the NaCl structure type, where Ag, Pb and Bi atoms are statistically disordered on the Na site and Q atoms occupy the Cl site. These compounds were synthesized by combining the elements in the appropriate ratio and heating under static vacuum at 900° C for 3 days. They are narrow gap semiconductors with band gaps in the range of 0.6 to 0.28 eV. The charge-transport properties were measured on ingots as a function of temperature. The compounds AgPbBiTe3, AgPbBiSe3, AgPbBiTe2.75Se0.25and AgPbBiTe2Se, undoped, possess an electrical conductivity in the range of 70 S/cm to 400 S/cm. These materials exhibit negative thermopower ranging from -40 μV/K to -160 μV/K at room temperature and thermal conductivity less than 1.30 W/mK.

Abstract
BACKGROUND Sarcoidosis is a chronic multisystem disease with a high prevalence of depression although this is often not recognised. It is not known how patients perceive their disease or the medications required for treatment. We hypothesised that perceptions of illness and beliefs about medications may relate to psychological distress in this condition. METHODS 81(42 female) patients with sarcoidosis completed the following: Hospital Anxiety and Depression Scale, Illness Perception Questionnaire, Beliefs about Medications Questionnaire. Demographic and clinical data were collected and the physician's perception of symptom severity and relationship to sarcoidosis recorded. RESULTS The prevalence of depression (23%) and anxiety (33%) was high and related to self reported symptoms of sarcoidosis. Those on current treatment reported different illness perceptions than those not, and illness perceptions related to anxiety and depression scores. The majority of the sample felt that sarcoid medications were unnecessary but few patients reported concerns about potential adverse consequences of taking them. Beliefs about medications were related to illness perceptions but not associated with anxiety or depression scores or with clinical perception of disease state. There were significant gender differences in perceptions of illness and beliefs about medications. CONCLUSIONS These data confirm earlier reports that anxiety and depression are common in patients with sarcoidosis and in turn perceptions of illness impact on emotional wellness in this disorder. Use of the Illness Perceptions Questionnaire in clinical practice may help to identify those patients who would benefit from interventions to change their perceptions of illness.

Abstract
OBJECTIVE To explore women's perceptions of "choice" of place of delivery in remote and rural areas where different models of maternity services are available. SETTING AND METHODS Remote and rural areas of the North of Scotland. A qualitative study design involved focus groups with women who had recent experience of maternity services. RESULTS Women had varying experiences and perceptions of choice regarding place of delivery. Most women had, or perceived they had, no choice, though some felt they had a genuine choice. When comparing different places of birth, women based their decisions primarily on their perceptions of safety. Consultant-led care was associated with covering every eventuality, while midwife-led care was associated with greater quality in terms of psycho-social support. Women engaged differently in the choice process, ranging from "acceptors" to "active choosers." The presentation of choice by health professionals, pregnancy complications, geographical accessibility and the implications of alternative places of delivery in terms of demands on social networks were also influential in "choice." CONCLUSIONS Provision of different models of maternity services may not be sufficient to convince women they have "choice." The paper raises fundamental questions about the meaning of "choice" within current policy developments and calls for a more critical approach to the use of choice as a service development and analytical concept.

Abstract
5116 Background: Cyclooxygenase-2 (COX-2) has been correlated with RCC stage and grade, and overexpression can lead to dysregulation of dendritic cells (DC) and CD4+/CD25+/FOXP3+ regulatory T cells (Treg). A previous trial of celecoxib in combination with IFNα2b in RCC (Rini et al, Cancer. 2006) demonstrated an association between more intense COX-2 RCC tumor staining and clinical response. Methods: Pts with cytokine-naïve mRCC with at least 10% maximal COX-2 tumor staining received IFNα2b MU five times/week plus celecoxib 400 mg BID continuously. Baseline tumor tissue was stained for COX-2, CD4+ and CD8+ T cells, Treg and DC (s100 and CD208). Peripheral blood prostaglandin E2 (PGE2), DC and Treg number/function and intracellular T cell cytokine production were measured at baseline, at the end of cycles 2 and 4 and at end of treatment. Activation of DC was assessed by IL-12 and IL-10 mRNA and protein production by ELISA. The primary endpoint was objective response rate (ORR). Secondary endpoints were DC / Treg number and cytokine production changes with therapy. The trial tested a null hypothesis of ORR <20% vs. alternative hypothesis of ORR >40%; beta = 0.8 and alpha = 0.05 (n = 34). Immune parameters were analyzed using non-parametric methods. Results: Fourteen pts have been enrolled; 79% male, median age 62 (range, 43–74) and 64% ECOG performance status 0. All pts had prior nephrectomy and 36% had received prior tyrosine kinase inhibitors (TKI); MSKCC Risk Group was favorable 14%, intermediate 71%, and unfavorable 14%. The ORR was 21% and 69% of pts experienced tumor shrinkage. Median PFS is 4.4 months. Toxicity was as expected for IFN therapy. Baseline 3+ COX-2 staining was associated with elevated peripheral blood PGE2 levels (p = 0.02), reduced DC IL-12 expression (p = 0.04) and reduction in IFN gamma-producing CD3+CD4+ T-cells (p = 0.04) compared to a control group of RCC pts with <10% 3+ COX-2 staining (n = 21). No significant changes in immunomodulatory cells were observed with therapy. Conclusions: COX-2 inhibition in combination with IFNα2b in maximal COX-2-expressing mRCC pts has clinical activity. COX-2 RCC tumor expression promotes an immunosuppressive phenotype. [Table: see text]

Abstract
OBJECTIVE To explore women's preferences for, and trade-offs between, key attributes of intrapartum care models. DESIGN Mixed-methods study using discrete choice experiments (DCEs) and focus groups. SETTING The North of Scotland. POPULATION Women from the catchment areas of eight rural maternity units in the North of Scotland. METHODS Based on current policy, 'model of care' and 'time travelled' were selected as key attributes of intrapartum care in remote and rural settings. A DCE questionnaire explored women's preferences for and trade-offs between these attributes. Focus groups validated the DCE attributes and provided valuable information about the drivers of women's preferences for place of delivery. MAIN OUTCOME MEASURES Preferences for attributes of intrapartum care. RESULTS Eight focus groups were conducted, and 877 eligible women completed the questionnaire. Overall, the DCE results found women preferred delivery in a unit to home birth and consultant-led care (CLC) to midwife-managed care (MMC). Women preferring CLC associated it with covering every eventuality and increased safety. Although women preferred shorter travel times, trade-offs indicated a willingness to travel for approximately 2 hours to get one's preferred choice. Focus group findings and subgroup DCE analysis showed heterogeneity of preferences related to experience, risk status, geographic location, perception of care and family circumstances. CONCLUSIONS In contrast to service redesign offering local midwife-managed intrapartum care, most rural women in our study expressed a preference to give birth in hospital and have CLC because they felt safer. Women were willing to travel for this but within limits. Qualitative results showed that women's preferences were influenced by their home and family context, beliefs and previous pregnancy experiences. Challenges for service redesign are to provide comprehensive obstetric services within acceptable travel time, while responding to the heterogeneity of women's preferences.

Abstract
OBJECTIVE This paper describes the ad hoc methodological concepts and procedures developed to improve the comparability of Nutrient databases (NDBs) across the 10 European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). This was required because there is currently no European reference NDB available. DESIGN A large network involving national compilers, nutritionists and experts on food chemistry and computer science was set up for the 'EPIC Nutrient DataBase' (ENDB) project. A total of 550-1500 foods derived from about 37,000 standardized EPIC 24-h dietary recalls (24-HDRS) were matched as closely as possible to foods available in the 10 national NDBs. The resulting national data sets (NDS) were then successively documented, standardized and evaluated according to common guidelines and using a DataBase Management System specifically designed for this project. The nutrient values of foods unavailable or not readily available in NDSs were approximated by recipe calculation, weighted averaging or adjustment for weight changes and vitamin/mineral losses, using common algorithms. RESULTS The final ENDB contains about 550-1500 foods depending on the country and 26 common components. Each component value was documented and standardized for unit, mode of expression, definition and chemical method of analysis, as far as possible. Furthermore, the overall completeness of NDSs was improved (>or=99%), particularly for beta-carotene and vitamin E. CONCLUSION The ENDB constitutes a first real attempt to improve the comparability of NDBs across European countries. This methodological work will provide a useful tool for nutritional research as well as end-user recommendations to improve NDBs in the future.

Abstract
OBJECTIVES To explore staff views on their roles, skills and training to deliver high quality and local intrapartum services in remote and rural settings against national recommendations. DESIGN Interview and postal survey. SETTING A stratified representative sample of remote and rural maternity units in Scotland (December 2002 to May 2003). PARTICIPANTS Staff proportionally representative of professional groups involved in maternity care. RESULTS Staff interviews took place at 11 units (response rate 93%). A subsequent postal survey included the interview sample and staff in a further 11 units (response rate 78%). Medical specialisation, workforce issues, and proposed regulatory evaluation of competencies linked to throughput raised concerns about the sustainability and safety of services, particularly for "generalists" in rural maternity care teams and for medical cover in small district general hospitals with large rural catchments. Risk assessment and decision making to transfer were seen as central for effective rural practice and these were influenced by rural context. Staff self-reported competence and confidence varied according to procedure, but noted service change appeared to be underway ahead of their preparedness. Self-reported competence in managing obstetric emergencies was surprisingly high, with the caveat that they were not independently assessed in this study. Staff with access to video conference technology reported low actual use although there was enthusiasm about its potential use. CONCLUSIONS Considerable uncertainties remain around staffing models and training to maintain maternity care team skills and competencies. Further research is required to test how this will impact on safety, appropriateness, and access and acceptability to rural communities.

Abstract
Localisation of the femoral head centre (FHC) during total knee arthroplasty (TKA) is necessary when assessing the overall alignment of the leg using an extramedullary guide for the femur. On-table radiographs for this purpose are time consuming and inconvenient. We describe a clinical method for estimating the FHC: it is marked 1.5 cm lateral to the point where the femoral artery crosses the line joining the pubic tubercle and the anterior superior iliac spine. Using this method the estimated FHC was within 15 mm of the anatomic centre in 84% of cases, and within 24 mm in 99%. This translates into possible knee alignment errors of 2 degrees and 3 degrees, respectively. As alignment error of up to +/-3 degrees is compatible with satisfactory clinical results of TKA, our method provides useful approximation of the FHC. For greater accuracy however, an on-table radiograph is recommended.

Abstract
Prevention of sexually transmitted infections is a priority in developed and developing countries. One approach to prevention is the use of topical microbicides, and one promising approach is the use of dendrimers, highly branched macromolecules synthesized from a polyfunctional core. Three new dendrimer products developed to provide stable and cost-efficient microbicides were initially evaluated in vitro for anti-herpes simplex virus activity and then in vivo by using a mouse model of genital herpes. From these experiments one product, SPL7013, was chosen for further evaluation to define the dose and duration of protection. Unformulated SPL7013 provided significant protection from genital herpes disease and infection at concentrations as low as 1 mg/ml and for at least 1 h following topical (intravaginal) administration of 10 mg/ml. This compound was then formulated into three vehicles and further evaluated in mouse and guinea pig models of genital herpes infection. In the murine evaluations each of the formulations provided significant protection at concentrations of 10 and 50 mg/ml. Formulated compounds provided protection for at least 1 h at a concentration of 10 mg/ml. From these experiments formulation 2V was chosen for dose ranging experiments using the guinea pig model of genital herpes. The guinea pig evaluations suggested that doses of 30 to 50 mg/ml were required for optimal protection. From these studies a lead compound and formulation (2V of SPL7013) was chosen for ongoing evaluations in primate models of simian immunodeficiency virus and Chlamydia trachomatis infection.

Abstract
OBJECTIVE To harmonize food classification and food composition databases, allowing comparability of consumption at both food and nutrient levels in Europe. DESIGN To establish the level of comparability at the food level, the EFCOSUM group benefited from the work already carried out within other European projects, which established a Euro Food Groups (EFG) classification system. Four food groups, ie bread, vegetables (excluding potatoes), fruits (excluding fruit juice) and fish and seafood, were judged on their applicability for making food consumption data comparable across countries at the food level. CONCLUSIONS It was concluded that the EFG system could be used but that still much work has to be done. For food consumption data to be collected in the future, the software that will be used should enable conversion of foods 'as consumed' to foods at the 'raw edible' level. With respect to comparability of nutrient intake estimations, EFCOSUM advises waiting for the European Nutrient Composition Database (ENDB) currently being prepared by the EPIC group. Until this is available, comparison of consumption data at the nutrient level cannot be carried out between countries.

Abstract
BACKGROUND Food consumption data are used for monitoring dietary indicators of health. In this context, there is a need for comparable (individual) data at the European level. The preference is to perform a pan-European survey able to generate data collected on the same basis. Until this can be realized, the existing data have to be made as comparable as possible. OBJECTIVE To identify solutions; to make existing food consumption data from nationally representative databases more comparable. METHODS General guidelines for the comparison of food intake data using currently available data were discussed and agreed upon in the EFCOSUM project team. RESULTS AND CONCLUSIONS Criteria were assessed with regard to the population involved, age of the survey, method of data collection, duration of the survey, the food classification system and the food composition tbl Based on these criteria, a maximum of 15 countries could provide food consumption data that can be made comparable at the individual level for the adult population. It is recommended to make data comparable at the food level, starting with vegetables (excluding potatoes), fruits (excluding fruit juices), fish (including shellfish) and bread. Comparability of foods is only possible at the 'raw edible' ingredient level. To achieve this, a large amount of work has to be undertaken. The approach of the EFG (Euro Food Groups) system is considered to be the best compromise between the different classification systems. Comparability at the nutrient level has to wait for the availability of a European Nutrient Database, like the one that is being developed within the EPIC context.

Abstract
OBJECTIVE A retrospective analysis was performed to assess gait in individuals with a long history of posterior knee instability. DESIGN Descriptive study. BACKGROUND There are few studies in the literature concerning evaluation of the biomechanics of the knee in patients with knee posterior instability. METHODS Nine individuals with posterior knee instability and a matched control group of uninjured subjects were tested in regards to knee kinematics and kinetics while walking and ascending and descending stairs. The mean follow up time for the individuals with posterior instability was 11.1 years. Individual satisfaction with the knee was measured by having participants complete the Flandry (also known as Hughston Clinic) self-assessment questionnaire. RESULTS It was found that patients with knee posterior instability who indicated a higher level of satisfaction on the Flandry score walked in a manner that demonstrated greater peak knee extensor torque during stance phase, while less satisfied patients with knee posterior instability demonstrated lower peak knee extensor torque. There was a significant correlation between the self-assessment score and the peak knee extensor torque during level walking (P=0.003). During stair ascent and descent, patients with posterior instability averaged lower knee extensor torque and power than the control subjects, but those differences were only statistically significant in power while descending stairs (P=0.048). CONCLUSIONS Individuals with chronic knee posterior instability modify their gait, and the adaptation can be predicted based upon the individuals self-assessment of their knee using the Flandry questionnaire. RELEVANCE These data suggest that gait retraining may be a valuable addition to the traditional muscle strengthening programs, which are commonly used during conservative management of knee posterior instability.

Abstract
The anterior recurrent branch of the anterior tibial artery is vulnerable during high tibial osteotomy. It may be injured during subperiosteal elevation of soft tissue from the lateral tibia--necessary for visualisation of the osteotomy or for placing the fixation device; or during excision of the infero-medial aspect of the fibular head--necessary to facilitate closure of the osteotomy. Recurrent bleeding from the operation site should draw attention to the possibility of a pseudo-aneurysm. Angiography helps in making an accurate diagnosis. Ligation of the feeding vessels provides effective treatment.

Abstract
With the availability of a dense genome-wide map of single nucleotide polymorphisms (SNPs), a central issue in human genetics is whether it is now possible to use linkage disequilibrium (LD) to map genes that cause disease. LD refers to correlations among neighbouring alleles, reflecting 'haplotypes' descended from single, ancestral chromosomes. The size of LD blocks has been the subject of considerable debate. Computer simulations and empirical data have suggested that LD extends only a few kilobases (kb) around common SNPs, whereas other data have suggested that it can extend much further, in some cases greater than 100 kb. It has been difficult to obtain a systematic picture of LD because past studies have been based on only a few (1-3) loci and different populations. Here, we report a large-scale experiment using a uniform protocol to examine 19 randomly selected genomic regions. LD in a United States population of north-European descent typically extends 60 kb from common alleles, implying that LD mapping is likely to be practical in this population. By contrast, LD in a Nigerian population extends markedly less far. The results illuminate human history, suggesting that LD in northern Europeans is shaped by a marked demographic event about 27,000-53,000 years ago.
