Abstract
5 Boroughs Partnership NHS Foundation Trust, in the Northwest of England, has trained over 500 staff in the Knowledge and Understanding Framework, level 1 personality disorder awareness training. This is a 3-day nationally devised training programme delivered via an innovative co-production model (i.e. co-delivery and partnership working with service users who have lived experience). This paper provides quantitative and qualitative information on the effectiveness of training delivery and also serves to provide some insight into the impact of service-user involvement via such a co-production model. Information on 162 participants using the Knowledge and Understanding Framework bespoke questionnaire (Personality Disorder Knowledge, Attitudes and Skills Questionnaire) suggests that the training can be effectively delivered by and within a local NHS Mental Health Trust. Results immediately post-training suggest an improvement in levels of understanding and capability efficacy and a reduction in negative emotional reactions. Indications from a 3-month follow-up suggest that while understanding and emotional reaction remain improved, capability efficacy regresses back to pre-training levels, suggesting the need for ongoing supervision and/or support to consolidate skills. Discussion includes guidelines for the implementation of a truly integrated co-production model of training provision, as well as advice relating to the maximization of long-term benefits.

Abstract
Warfarin is an oral anticoagulant that requires frequent therapeutic drug monitoring due to a narrow therapeutic window, considerable interindividual variability in drug response, and susceptibility to drug-drug and drug-diet interactions. Enantiomeric separation and quantification of warfarin enantiomers and clinically important major hydroxylation metabolites are essential for drug interaction studies and phenotypic characterization of CYP2C9 and CYP3A4, the major cytochrome P450 (CYP) enzymes involved in warfarin metabolism. Here, we describe the development and validation of a chiral high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)-based quantification of R-warfarin, S-warfarin, S-7-hydroxywarfarin (the major CYP2C9 metabolite) and (9R;10S)-10-hydroxywarfarin (the CYP3A4 metabolite) in human plasma. Simple protein precipitation-based extraction showed good recovery of analytes (82.9 - 96.9%). The developed method exhibited satisfactory intra-day and inter-day accuracy and precision. The lower limits of detection were 0.25 nM (or ~0.08 ng/mL) for the warfarin enantiomers and 0.1 nM (or ~0.04 ng/mL) for S-7-hydroxywarfarin and (9R;10S)-10-hydroxywarfarin using only 50 µL plasma during extraction. The validated method was successfully applied to analyze plasma samples obtained from a healthy human subject who enrolled in a clinical drug interaction study involving warfarin.

Abstract
The pattern of changes in cerebral glucose metabolism occurring with normal aging has been unclear. Advances in imaging technology, such as improved resolution and anatomical referencing, allow for more precise regional measurement than previously possible. This study explored cerebral glucose metabolism in 17 normal controls ranging in age from 20 to 74 years. High resolution PET scanning, with MRI-based regions of interest correcting for partial volume and atrophy effects, revealed a linear association between advancing age and declining cerebral glucose metabolism. The decline averaged 8% per decade for the whole brain. Changes were most pronounced in limbic structures, and could be implicated in age-associated memory loss.

Abstract
Mutations in the gene encoding muscle-specific calpain 3 protease cause limb girdle muscular dystrophy type 2A. Calpainopathy is characterised by progressive symmetrical atrophy of pelvic, scapular and trunk muscles with an elevated creatine kinase. Most patients develop symptoms in childhood and lose the ability to walk by the age of 40 years. We describe a man who presented with foot drop at the age of 41 years, together with neurophysiological, histopathological and genetic data. This is the first report of calpainopathy presenting as foot drop, and widens the phenotype associated with this disease.

Abstract
In the late 19th century, Charles Egeson, a map compiler at the Sydney Observatory, carried out some of the earliest research on climatic cycles, linking them to about 33-year cycles in solar activity, and predicted that a devastating drought would strike Australia at the turn of the 20th century. Eduard Brückner and William J. S. Lockyer, who, like Egeson, found similar cycles, with notable exceptions, are also, like the map compiler, mostly forgotten. But the transtridecadal cycles are important in human physiology, economics and other affairs and are particularly pertinent to ongoing discusions of climate change. Egeson's publication of daily weather reports preceded those officially recorded. Their publication led to clashes with his superiors and his personal life was marked by run-ins with the law and, possibly, an implied, but not proven, confinement in an insane asylum and premature death. We here track what little is known of Egeson's life and of his bucking of the conventional scientific wisdom of his time with tragic results.

Abstract
Abstract
INTRODUCTION:Rates of CPM are reported to be increasing, yet factors driving this trend are unclear. We performed this analysis to determine if increasing rates of CPM are being driven by increased recognition of risk factors for contralateral breast cancer (CBC) or by treatment factors related to the index lesion.METHODS:From 1997-2005, 2967 patients with Stage 0-III primary unilateral breast cancer underwent mastectomy at MSKCC and were entered into a prospectively maintained database. Demographic, tumor and treatment factors were abstracted and comparisons made between patients who did and did not undergo CPM within one year of treatment for their index cancer. Generalized estimating equations were used to fit logistic regression models to identify independent predictors of CPM.RESULTS:The overall rate of CPM was 13.8%(n=408), increasing from 6.7% in 1997 to 24.4% in 2005 (p<0.0001). The median age of CPM pts was 44.9 vs 53.2 in the non-CPM group (p<.001) and only 7% of CPM pts were non-white compared to 25% of non-CPM pts (p<.001). Although 69% of CPM pts had a family history (FH) of breast cancer (vs 40% non-CPM; p<.001) only 8% had 2 or more first degree relatives affected. Genetic testing was performed in 29% of CPM pts; of those 37 (31%) were positive. The use of MRI increased from 1.3% to 36.3%of cases over the study period. MRI at diagnosis (43% vs 16%) and MRI generated biopsy in the contralateral or bilateral breasts (29% vs 4%) were strongly associated with CPM (p<.0001). Prior attempts at breast conservation (BCT) (28% vs 16%; p<.001) were more common in the CPM group, but number of attempts did not differ between groups. Patients undergoing CPM were more likely to have DCIS versus an invasive histology (p<0.0001), and of those with invasive disease, CPM patients had smaller tumors (1.2cm vs. 1.8cm, p<0.0001) and were more likely to be node negative (53% vs 43%, p<0.0001). ER, PR, and HER2 status were not associated with CPM. CPM rates among surgeons ranged from 9.8% to 26%. Multivariate analysis of predictors of CPM for 2387 patients with complete data is shown in the Table.VariableORp95%CIWhite race3.6<0.00012.4-5.4Age<502.3<0.00011.8-3.1FH breast cancer2.9<0.00012.3-3.7MRI at Dx2.2<0.00011.7-2.8BCT attempted1.60.000081.2-2.1Reconstruction3.2<0.00012.3-4.5DCIS histology1.40.021.1-1.9*adjusted for surgeonCONCLUSIONS: Factors associated with clinical management of the index cancer such as preoperative MRI with the potential for additional biopsy, failed attempt at BCT, and breast reconstruction were strongly associated with CPM. Age and FH were also independent predictors; however the FH profiles of CPM pts in this series do not support increased recognition of mutation carriers and truly high risk FH as a major cause of increasing rates of CPM. The lack of association with ER status, which results in treatment that decreases the risk of CBC, provides additional support that patients may be choosing CPM for reasons other than future risk. These data suggest that the need for additional procedures during management of the index cancer may be contributing to the increasing use of CPM among a relatively moderate risk patient population. Efforts to optimize BCT and minimize unnecessary tests may help to curb this trend.

Abstract
BACKGROUND Systematic reviews are most helpful if they are up-to-date. We did a systematic review of strategies and methods describing when and how to update systematic reviews. OBJECTIVES To identify, describe and assess strategies and methods addressing: 1) when to update systematic reviews and 2) how to update systematic reviews. SEARCH STRATEGY We searched MEDLINE (1966 to December 2005), PsycINFO, the Cochrane Methodology Register (Issue 1, 2006), and hand searched the 2005 Cochrane Colloquium proceedings. SELECTION CRITERIA We included methodology reports, updated systematic reviews, commentaries, editorials, or other short reports describing the development, use, or comparison of strategies and methods for determining the need for updating or updating systematic reviews in healthcare. DATA COLLECTION AND ANALYSIS We abstracted information from each included report using a 15-item questionnaire. The strategies and methods for updating systematic reviews were assessed and compared descriptively with respect to their usefulness, comprehensiveness, advantages, and disadvantages. MAIN RESULTS Four updating strategies, one technique, and two statistical methods were identified. Three strategies addressed steps for updating and one strategy presented a model for assessing the need to update. One technique discussed the use of the "entry date" field in bibliographic searching. Statistical methods were cumulative meta-analysis and predicting when meta-analyses are outdated. AUTHORS' CONCLUSIONS Little research has been conducted on when and how to update systematic reviews and the feasibility and efficiency of the identified approaches is uncertain. These shortcomings should be addressed in future research.

Abstract
Mitochondria play a central role in the secretion of insulin by pancreatic beta-cells, and pathogenic mutations of mitochondrial DNA (mtDNA) can cause diabetes. The aetiology of type 2 diabetes has a strong genetic component, raising the possibility that genetic variants of mtDNA alter the risk of developing the disorder. Recent studies have produced conflicting results. By studying 897 UK cases of type 2 diabetes and 1010 population-matched controls, it is shown that European mtDNA haplogroups are unlikely to play a major role in the risk of developing the disorder.

Abstract
AIMS A subset of patients who present as if they have Type 2 diabetes have positive pancreatic autoantibodies, and have been referred to as having latent autoimmune diabetes in adults (LADA). We assessed the prevalence and clinical characteristics of patients with glutamic acid decarboxylase antibodies (GADA) in a cohort clinically selected for Type 2 diabetes and determined the presence of diabetes and GADA in their first-degree relatives. METHODS GADA were measured in 2059 subjects, not known to be related, and clinically selected as having Type 2 diabetes for genetic studies. Clinical characteristics were compared in GADA positive and GADA negative subjects. Diabetes and GAD antibody status were compared in 208 first-degree relatives of GADA positive and GADA negative probands. RESULTS Of the subjects, 136 (7%) were GADA positive. Compared with the GADA negative subjects, they were slimmer (P < 0.001), diagnosed at a younger age (P = 0.011) and progressed to insulin faster (P < 0.001). Thirty-three per cent of GADA positive subjects had a first-degree relative with diabetes compared with 42% of GADA negative subjects (P = 0.034). The overall prevalence of GADA was similar in the first-degree relatives of GADA positive and GADA negative probands (4 v 5%), and 19 of 22 (86%) diabetic relatives of GADA positive probands were GADA negative. CONCLUSION Despite clinically selecting a Type 2 diabetes cohort, 7% were GADA positive with an altered phenotype. These GADA positive patients had a strong family history of non-autoimmune diabetes. This suggests that, in this subgroup of patients, autoimmune pancreatic beta-cell destruction occurs on a background of Type 2 diabetes genetic susceptibility.

Abstract
AIMS/HYPOTHESIS Animal models indicate that even exposure to mild maternal hyperglycaemia in utero is detrimental to the beta cell function of the offspring, but evidence of this in humans is limited. In Europids who are diagnosed with type 2 diabetes before the age of 50 years, the risk of diabetes in the offspring of the diabetic mothers is greatly increased compared with the risk in those born to diabetic fathers. We hypothesised that offspring born to mothers with young-onset type 2 diabetes would have been exposed to mild hyperglycaemia in utero, so we studied the impact of this on their beta cell function. SUBJECTS AND METHODS We measured beta cell function using early insulin response (EIR) after oral glucose; insulin resistance using HOMA; and HbA(1c) in 568 non-diabetic adult offspring born to parents with type 2 diabetes (mean age 55.8 years), split according to which parent was affected (in 327 it was the mother) and parental age of diagnosis: <50 years (n=117) or > or =50 years. To reduce the impact of genetic susceptibility, the offspring of affected fathers were used as control subjects. RESULTS Offspring of mothers with young-onset type 2 diabetes had lower EIR (log EIR 4.32, 95% CI [4.14-4.51] vs 4.63 [4.43-4.83] p=0.02) and higher HbA(1c) (4.89% [4.79-4.99] vs 4.68% [4.57-4.79] p=0.02) than the offspring of fathers with young-onset type 2 diabetes. Insulin sensitivity was similar in the two groups. There were no differences in EIR or HbA(1c) between the offspring born to mothers and fathers who were diagnosed after the age of 50 years. CONCLUSIONS/INTERPRETATION We conclude that the offspring of mothers with young-onset type 2 diabetes have a reduction in beta cell function. This is consistent with exposure to mild maternal hyperglycaemia programming beta cell function.

Abstract
Background Considerable interest exists in the potential therapeutic value of dietary supplementation with the omega-3 fatty acids. Given the interplay between pro-inflammatory omega-6 fatty acids, and the less pro-inflammatory omega-3 fatty acids, it has been thought that the latter could play a key role in treating or preventing asthma. The purpose was to systematically review the scientific-medical literature in order to identify, appraise, and synthesize the evidence for possible treatment effects of omega-3 fatty acids in asthma. Methods Medline, Premedline, Embase, Cochrane Central Register of Controlled Trials, CAB Health, and, Dissertation Abstracts were searched to April 2003. We included randomized controlled trials (RCT's) of subjects of any age that used any foods or extracts containing omega-3 fatty acids as treatment or prevention for asthma. Data included all asthma related outcomes, potential covariates, characteristics of the study, design, population, intervention/exposure, comparators, and co interventions. Results Ten RCT's were found pertinent to the present report. Conclusion Given the largely inconsistent picture within and across respiratory outcomes, it is impossible to determine whether or not omega-3 fatty acids are an efficacious adjuvant or monotherapy for children or adults. Based on this systematic review we recommend a large randomized controlled study of the effects of high-dose encapsulated omega-3 fatty acids on ventilatory and inflammatory measures of asthma controlling diet and other asthma risk factors. This review was limited because Meta-analysis was considered inappropriate due to missing data; poorly or heterogeneously defined populations, interventions, intervention-comparator combinations, and outcomes. In addition, small sample sizes made it impossible to meaningfully assess the impact on clinical outcomes of co-variables. Last, few significant effects were found.

Abstract
STUDY DESIGN Systematic review. OBJECTIVE To review sexuality in persons with spinal cord injuries (SCIs), and to report the effectiveness of erectile interventions. METHODS Reports from six databases (1966-2003), selected annual proceedings (1997-2002) and manufacturer's information were screened against eligibility criteria. Included reports were abstracted and data pooled from case-series reports regarding intracavernous injections and sildenafil. RESULTS From 2127 unique reports evaluated, 49 were included. Male sexual dysfunction was addressed in these reports of several interventions (behavioural therapy, topical agents, intraurethral alprosatadil, intracavernous injections, vacuum tumescence devices, penile implants, sacral stimulators and oral medication). Penile injections resulted in successful erectile function in 90% (95% CI: 83%, 97%) of men. Sildenafil resulted in 79% (95% CI: 68%, 90%) success; the difference in efficacy was not statistically significant. Five case-series reports involving 363 participants with penile implants demonstrated a high satisfaction rate, but a 10% complication rate. CONCLUSIONS A large body of evidence addressing sexuality in males focuses on erection. Penile injection, sildenafil and vacuum devices generally obviate the need for penile implants to address erectile dysfunction. Interventions may positively affect sexual activity in the short term. Long-term sexual adjustment and holistic approaches beyond erections remain to be studied. Rigorous study design and reporting, using common outcome measures, will facilitate higher quality research. This will positively impact patient care. SPONSORSHIP Agency for Healthcare Research and Quality, US Department of Health and Human Services, 2101 East Jefferson Street, Rockville, MD 20852, USA.

Abstract
STUDY DESIGN Systematic review. OBJECTIVES To review systematically fertility of persons with spinal cord injuries (SCI) and their partners. METHODS Reports from six databases (1966-2003), selected annual proceedings (1997-2002) and manufacturer's information were screened against eligibility criteria. Searches covered female obstetrical issues, and the efficacy of vibration and electroejaculation for males, as well as advanced fertility (AF) treatments for partners of SCI males. Data were pooled from case-series reports on SCI males' ejaculation, and pregnancies and live births for partners of SCI males. RESULTS In all, 2,127 unique reports were evaluated, of which 66 reports were included. No studies investigated fertility in SCI females. Ejaculation interventions in the last decade resulted in response rates of 95% (95% confidence intervals (CI) 91%, 99%), with 100% response rate reported in several recent publications. A total of 13 studies (1993-2001) yielded pregnancy rates of 51% (95% CI 42%, 60%) in partners of SCI males. Of these, 11 studies (1993-2003) yielded live birth rates of 41% (95% CI 33%, 49%). CONCLUSIONS Fertility of SCI males is extensively studied. Semen for fertility purposes can generally be obtained using vibration and electroejaculation. AF techniques are increasing pregnancy rates. Research is needed to improve sperm quality. Freezing of sperm is unlikely to significantly improve fertility rates. Fertility of SCI females is addressed only in case reports and opinion articles. The opinion that female fertility is unaffected by SCI should be further investigated using appropriate research methodology.
