Abstract
BACKGROUND The Scale of Emotional Development - Short (SED-S) captures the level of emotional development in persons with a disorder of intellectual development (DID) with 200 items on five developmental levels. The study aims to develop a brief version of the SED-S. METHODS Based on item analysis (proportions, χ2 -test, Spearman's ρ and corrected item-total correlation), a brief version of the SED-S was developed in a sample of 224 adults with a DID (n1 ) and validated in a second independent matched sample (n2 = 223). RESULTS Item reliability ranged per item set from Cronbach's α = 0.835 to 0.924. Weighted kappa resulted in κω = 0.743 (P < 0.001, 95% confidence interval = 0.690-0.802). Overall agreement of the brief version with the original SED-S was PO = 0.7. The brief version of the SED-S showed weaknesses in distinguishing level 2 from the adjacent levels. CONCLUSIONS The brief version of the SED-S showed good reliability and moderate to good validity results. Items of phase 2 and, to some degree, of phase 5 should be revised to further improve the psychometric properties of the scale.

Abstract
Personalized cancer vaccines aim to activate and expand cytotoxic antitumor CD8+ T cells to recognize and kill tumor cells. However, the role of CD4+ T cell activation in the clinical benefit of these vaccines is not well defined. We previously established a personalized neoantigen vaccine (PancVAX) for the pancreatic cancer cell line Panc02, which activates tumor-specific CD8+ T cells but required combinatorial checkpoint modulators to achieve therapeutic efficacy. To determine the effects of neoantigen-specific CD4+ T cell activation, we generated a vaccine (PancVAX2) targeting both major histocompatibility complex class I- (MHCI-) and MHCII-specific neoantigens. Tumor-bearing mice vaccinated with PancVAX2 had significantly improved control of tumor growth and long-term survival benefit without concurrent administration of checkpoint inhibitors. PancVAX2 significantly enhanced priming and recruitment of neoantigen-specific CD8+ T cells into the tumor with lower PD-1 expression after reactivation compared with the CD8+ vaccine alone. Vaccine-induced neoantigen-specific Th1 CD4+ T cells in the tumor were associated with decreased Tregs. Consistent with this, PancVAX2 was associated with more proimmune myeloid-derived suppressor cells and M1-like macrophages in the tumor, demonstrating a less immunosuppressive tumor microenvironment. This study demonstrates the biological importance of prioritizing and including CD4+ T cell-specific neoantigens for personalized cancer vaccine modalities.

Abstract
This project explored the selection process of commercially available virtual reality (VR) games for traumatic brain injury rehabilitation. Occupational therapy practitioners (OTPs) developed a classification framework that they used to evaluate VR games. The classification framework focused on movements required to effectively play the game, cognitive demand, position for game play, ease in menu navigation, and perceived therapeutic applications. OTPs used the ratings to aid in game selection and identified relevant game examples that allowed customizable settings and basic navigation with a game focus on functional activities. The OTPs and the research team identified the need for further work on accessibility and adaptability of game features (e.g., difficulty and limb usage) allowing for more individualization to optimize outcomes of VR-enhanced rehabilitation. The classification framework was useful in evaluating the potential therapeutic benefit of commercially available VR games. However, trial of the game by clinicians prior to use was still warranted.

Abstract
BACKGROUND Intellectual disability (ID) is often associated with delays in emotional development (ED). The Scale of Emotional Development - Short (SED-S) was developed to assess the level of ED and to adapt treatment and care accordingly. METHODS In a sample of 724 adults from five study sites in three countries, a confirmatory factor analysis with a one-factor model was conducted on the entire dataset as well as in different subgroups. Furthermore, internal consistency was investigated using Cronbach's alpha. RESULTS The confirmatory factor analysis indicated that a single-factor model fits the SED-S data well. The subgroup analyses revealed good model fit, regardless of the severity of ID and irrespective of sex or the presence of autism spectrum disorder or psychiatric disorders. Internal consistency was excellent for the entire sample (Cronbach's alpha = 0.93) and various subgroups (0.869-0.938). CONCLUSION The results of this study suggest that the SED-S is psychometrically sound and can be used to assess the level of ED in adults with ID.

Abstract
Abstract
Pancreatic ductal adenocarcinoma (PDAC) is most often diagnosed at an advanced stage. Newly diagnosed patients therefore have a dismal five-year survival rate of 11%. However, PDAC progresses from pre-invasive pancreatic intraepithelial neoplasia (PanIN) over at least a decade. Throughout this transition, the tissue microenvironment becomes increasingly immunosuppressive. Early PanINs may therefore be more amenable to immune-based interception strategies; however, little is known about the pre-malignant lesion immune microenvironment in PDAC. We hypothesized that the identification of the immune landscape of PanINs will elucidate the immuno-dynamic changes that occur during PanIN-to-PDAC progression and identify novel strategies for intercepting PDAC. Here, we use an inducible mouse model to study the evolution of immunosuppression from PanINs to PDAC. We pair spatial molecular profiling of our mouse model with profiling of human tissue in a cohort of patients with normal tissue, chronic pancreatitis, PanIN, and PDAC. To examine the evolution of the immune microenvironment throughout PanIN-to-PDAC progression, we first optimized a tamoxifen-inducible Pdx1-CreERT2 mouse that controls KRASG12D expression and knocks out p53. The impact of KRASG12D expression on the immune cell landscape in PanIN and PDAC lesions was examined by immunohistochemistry (IHC) and RNA in situ hybridization on mouse pancreas. We used imaging mass cytometry (IMC) of 35 immune markers to better classify and quantify the immune cell subtypes. Our analyses thus far reveal increased Tregs as PanINs progress to PDAC. Furthermore, although CD3+ T cells are recruited to tumors, these immune cells are strictly restricted to the immediate edge of the tumor and predominantly consist of Tregs. For our human analyses, FFPE pancreas sections from treatment naïve patients who had undergone surgical resection without neoadjuvant chemotherapy were evaluated. Each section contained regions of normal tissue, chronic pancreatitis, PanIN and PDAC. These were evaluated using IHC, IMC, and spatial transcriptomics to allow us to spatially evaluate the immune populations associated with lesions and PDAC. The relative density and localization of myeloid and lymphoid cell types in both PanIN and PDAC regions revealed an initial influx of CD8+ and CD4+ T cells to PanINs and a progressively immunosuppressive microenvironment in subsequent stages. While PanINs and PDAC both recruited immune cells, the phenotypes of the immune infiltrates were distinct and revealed unique immune pathways that could contribute to immunosuppression as PanINs develop into PDACs. Our proteomic and transcriptomic data from mouse and human pancreas show that mutant KRAS driven premalignant lesions recruit an evolving immune response that readily becomes immunosuppressive as progression to PDAC occurs.

Abstract
Abstract
Study question
Does rapid or delayed insemination after egg retrieval affect fertilization, blastocyst development and live birth rates in CI and ICSI cycles?
Summary answer
When performing CI or ICSI <1.5h and >6.5h after retrieval, detrimental effects are moderate on fertilization but do not impact blastocyst usage and birth rates.
What is known already
Several studies have shown that CIor ICSI performed between 3 to 5 h after oocyte retrieval has improved laboratory outcomes. However, some studies indicate that insemination of oocytes, by either CI or ICSI, within 2 hours or more than 8 hours after oocyte retrieval has a detrimental effect on the reproductive outcome. With some ART centres experiencing an increase in workload, respecting these exact time intervals is frequently challenging.
Study design, size, duration
A single-center retrospective cohort analysis was performed on 6559 patients (9575 retrievals and insemination cycles) between January 1st2017 to July 31st2019. The main outcome measures were live-birth rates. Secondary outcomes included analysis of fertilization per all oocytes retrieved, blastocyst utilization, clinical pregnancy, and miscarriage rates. All analyses used time of insemination categorized in both CI and ICSI cycles. Fertilization rates across categories was analyzed by ANOVA and pregnancy outcomes compared using Chi-square tests.
Participants/materials, setting, methods
As part of laboratory protocol, oocyte retrieval was performed 36 h post-trigger. Cycles involving injection with testicular/epidydimal sperm, donor or frozen oocytes were excluded. The time interval between oocyte retrieval and insemination was analyzed in eight categories: 0 (0- <0.5h), 1 (0.5-<1.5h), 2 (1.5-<2.5h), 3 (2.5-<3.5h), 4 (3.5-<4.5), 5 (4.5-<5.5), 6 (5.5-<6.5) and 7 (6.5-<8h). The number of retrievals in each group (0–7) was 586, 1594, 1644, 1796, 1836, 1351, 641 and 127 respectively.
Main results and the role of chance
This study had a mean patient age of 36.0 years and mean of 12.2 oocytes per retrieval in each category. There were 4,955 CI and 4,620 ICSI retrievals. The smallest groups were time category 7 and 0 for CI and ICSI respectively. The results showed that the mean fertilization rate per egg retrieved for CI ranged from 54.1 to 64.9% with a significant difference between time category 0 and 5 (p < 0.001) and category 1 and 5 (p < 0.0.001). Mean fertilization rate for ICSI per egg retrieved ranged from 52.8 to 67.3% with no significant difference between time categories compared to category 5. Blastocyst utilization rate for CI and ICSI were not significantly different for all time categories. In the CI and ICSI groups there were 6,540 and 6,178 total fresh and frozen transfers. The miscarriage and clinical pregnancy rate in CI and ICSI were not significantly different across time categories. The overall mean live birth rate for CI was 32.4% (range: 23.1 to 35.5%). Live-birth rates differed significantly (p = 0.04) in CI with time categories 0 and 7 the lowest. In the ICSI group, the overall mean live birth rate was 30.8% (range: 29.1 to 35.7%),with no significant differences between time categories.
Limitations, reasons for caution
As this is a retrospective study, the influence of uncontrolled variables cannot be excluded. The group spread was uneven with the early and late time categories having the lowest number of representative retrievals and this could have affected the results obtained.
Wider implications of the findings: Our results indicate that both CI and ICSI are optimal when performed between 1.5–6.5 hours after oocyte retrieval. Further prospective studies on reproductive outcomes related to time of insemination are warranted. This data indicates a minimal detrimental effect when it is untenable to follow strict insemination time intervals.

Abstract
PURPOSE Coronavirus 2019 (COVID-19) was first identified in December 2019 with millions of cases reported globally in the succeeding months. Initial hospitalisation strives to minimise multisystem organ failure and of those that survive, individuals can present with profound rehabilitation needs. The purpose of this case series is to describe occupational therapy (OT) and special technology considerations for three male Veteran patients hospitalised with suspected or confirmed COVID-19. Methods: This is a descriptive case series using a retrospective electronic health record review at a Veterans Administration hospital. The case series includes three male Veterans with confirmed or suspected COVID-19 (ages 69-78) who were referred to OT. The cases were selected to demonstrate the novel use of technology and strategies to reduce the risk of transmission. In two of three of our cases, we describe acute rehabilitation with a focus on activity tolerance, participation in occupations, and discharge planning. In all cases, we measured vital signs and activity tolerance as primary outcomes. Results and conclusions: The findings suggest that outcome measures focussing on activity tolerance to maintain stable vital signs during the recovery phase is central to the progression of activities. We observed in our cases that the Person-Environment-Occupation-Performance (PEOP) model can guide practice and complement the medical model in management of these patients. We utilised technology to engage family members in the rehabilitation care and minimise exposure risks.IMPLICATIONS FOR REHABILITATIONAcute occupational therapy for rehabilitation early in the recovery of Cornavirus-2019 can be guided by the Person-Occupation-Environment-Performance model as seen in this case series of three Veteran patients.Assistive technology can serve dual roles in supporting the rehabilitation of individuals with Cornavirus-2019 and lowering the risk of virus transmission to staff.

Abstract
Introduction The Veterans Health Administration (VHA) registered nurse (RN) Transition to Practice (TTP) program is a 1-year comprehensive, standardized curriculum taught for entry-level nurses to assist them in transitioning to VA-trained, competent, professional RNs. The TTP program includes revised modules on Evidence-Based Practice (EBP) clinical decision making. The revised curriculum emphasizes EBP as a problem-solving approach to clinical decision making rather than a project-based approach to implement practice changes. The goal of this quality improvement project was to evaluate the content, delivery, and outcomes of a revised Evidence-Based Practice Curriculum (EBPC) for use in the VHA RN TTP program. Methods Focus groups were conducted with TTP coordinators, who teach the program and facility EBP content experts from 32 VHA Medical Centers. All attended a three-day face-to-face training at a central location. Qualitative data were managed and analyzed with a rapid assessment process. Discussion Leaders within and outside of organizations are commonly believed to affect the success of implementing and sustaining any program or initiative through their influence on organizational climate, leadership processes, and leadership alignment across multiple levels of leadership. Our findings were in line with other research showing that leaders should prioritize EBP and fuel it with resources to create sustainable change. Conclusions In conclusion, the EBPC was reviewed very favorably by all who planned to use it in their facilities in teaching the content to practicing registered nurses. Future evaluation will focus on the degree to which faculty use the program, how they use the modules, and what feedback nurses provide after exposure to EBPC.

Abstract
Background Using personal experience stories as teaching tools, clinical narratives are an effective means for sharing the art of nursing practice and provide insight into nurses' critical thinking and clinical proficiency. Using clinical narratives to assess curriculum effectiveness provides important insights into changed practice and learning beyond the classroom. Aim This article provides an example of using clinical narratives in the evaluation of the Department of Veterans Health Affairs Office of Nursing Services (ONS) Evidence Based Practice Curriculum (EBPC). Methods As part of a larger mixed-method evaluation of the EBPC, clinical narrative methods were employed to describe one incident where participants (n=3) applied at least two of three evidence based practice components (best available evidence; clinical expertise; patient preference). Results Examination of clinical narratives demonstrated successful application of key components of evidence based practice and an integration into individual nursing practice beyond data obtained from other evaluation methods. Conclusions Incorporating rich clinical narratives into a rigorous mixed-method program evaluation protocol provides insights beyond information uptake, satisfaction, efficacy, or competency assessment scores.

Abstract
We report on the all-optical production of Bose-Einstein condensates in microgravity using a combination of grey molasses cooling, light-shift engineering and optical trapping in a painted potential. Forced evaporative cooling in a 3-m high Einstein elevator results in 4×10^{4} condensed atoms every 13.5 s, with a temperature as low as 35 nK. In this system, the atomic cloud can expand in weightlessness for up to 400 ms, paving the way for atom interferometry experiments with extended interrogation times and studies of ultracold matter physics at low energies on ground or in Space.

Abstract
We propose new multidimensional atom optics that can create coherent superpositions of atomic wave packets along three spatial directions. These tools can be used to generate light-pulse atom interferometers that are simultaneously sensitive to the three components of acceleration and rotation, and we discuss how to isolate these inertial components in a single experimental shot. We also present a new type of atomic gyroscope that is insensitive to parasitic accelerations and initial velocities. The ability to measure the full acceleration and rotation vectors with a compact, high-precision, low-bias inertial sensor could strongly impact the fields of inertial navigation, gravity gradiometry, and gyroscopy.

Abstract
BACKGROUND Outcomes following admission to residential alternatives to standard in-patient mental health services are underresearched. AIMS To explore short-term outcomes and costs of admission to alternative and standard services. METHOD Health of the Nation Outcome Scales (HoNOS), Threshold Assessment Grid (TAG), Global Assessment of Functioning (GAF) and admission cost data were collected for six alternative services and six standard services. RESULTS All outcomes improved during admission for both types of service (n = 433). Adjusted improvement was greater for standard services in scores on HoNOS (difference 1.99, 95% CI 1.12-2.86), TAG (difference 1.40, 95% CI 0.39-2.51) and GAF functioning (difference 4.15, 95% CI 1.08-7.22) but not GAF symptoms. Admissions to alternatives were 20.6 days shorter, and hence cheaper (UK pound3832 v. pound9850). Standard services cost an additional pound2939 per unit HoNOS improvement. CONCLUSIONS The absence of clear-cut advantage for either type of service highlights the importance of the subjective experience and longer-term costs.

Abstract
The study of exclusive π(±) electroproduction on the nucleon, including separation of the various structure functions, is of interest for a number of reasons. The ratio RL=σL(π-)/σL(π+) is sensitive to isoscalar contamination to the dominant isovector pion exchange amplitude, which is the basis for the determination of the charged pion form factor from electroproduction data. A change in the value of RT=σT(π-)/σT(π+) from unity at small -t, to 1/4 at large -t, would suggest a transition from coupling to a (virtual) pion to coupling to individual quarks. Furthermore, the mentioned ratios may show an earlier approach to perturbative QCD than the individual cross sections. We have performed the first complete separation of the four unpolarized electromagnetic structure functions above the dominant resonances in forward, exclusive π(±) electroproduction on the deuteron at central Q(2) values of 0.6, 1.0, 1.6 GeV(2) at W=1.95 GeV, and Q(2)=2.45 GeV(2) at W=2.22 GeV. Here, we present the L and T cross sections, with emphasis on RL and RT, and compare them with theoretical calculations. Results for the separated ratio RL indicate dominance of the pion-pole diagram at low -t, while results for RT are consistent with a transition between pion knockout and quark knockout mechanisms.

Abstract
PURPOSE Acute upper respiratory infections (URI) are the second most common diagnosis in primary care offices. As treatments have limited effectiveness, patient counseling regarding expectations for the course of the URI is an important aspect of care. It is unknown how accurate patients, clinicians or questionnaires such as the Wisconsin Upper Respiratory Symptom Survey (WURSS) instrument are at predicting URI severity and duration, and whether these predictions should be used to counsel patients. METHODS Seven hundred and nineteen individuals with recent onset cold in community clinic settings participated. Participants and clinicians predicted the severity and duration of the URI and participants completed the WURSS instrument at initial visit. Subsequent URI global severity was calculated as area under the curve using an average of twice-daily WURSS-21 self-reports as the y-axis and illness duration as the x-axis. URI duration was determined by self-report of beginning and end of illness. Linear regression analysis was used to correlate baseline predictions with subsequent outcomes. Analyses by gender, age and income were also performed. RESULTS There was no significant association between participant and clinician predictions of severity or duration. Initial WURSS values explained 0.119 (95% CI: 0.074-0.163) of the variance in subsequent severity outcomes. There were no significant differences in associations by age, gender or income. CONCLUSIONS Clinicians should not use their predictive assessments or their patients' predictions when advising patients on the expected course of a URI. This study also suggests that the WURSS instrument could give some predictive information, but whether this is clinically useful is uncertain.

Abstract
Lifetime risk of developing endometrial cancer in Lynch syndrome carriers is very high and females are also at an increased risk of developing ovarian cancer. The aim of the study was to determine the impact of gynecological screening in MSH2 mutation carriers. Gynecological cancer incidence and overall survival was compared in female mutation carriers who received gynecological screening (cases) and in matched controls. Controls were randomly selected from non-screened mutation carriers who were alive and disease-free at the age the case entered the screening program. Median age to diagnosis of gynecological cancer was 54 years in the screened group compared to 56 years in controls (p = 0.50). Stage I or II cancer was diagnosed in 92% of screened patients compared to 71% in the control group (p = 0.17). Two of three deaths in the screened group were the result of ovarian cancer. Mean survival in the screened group was 79 years compared to 69 years in the control group (p = 0.11), likely associated with concomitant colonoscopy screening. Gynecological screening did not result in earlier gynecologic cancer detection and despite screening two young women died from ovarian cancer suggesting that prophylactic hysterectomy with bilateral salpingo-oophorectomy be considered in female mutation carriers who have completed childbearing.

Abstract
OBJECTIVE To examine the clinical effectiveness and cost-effectiveness of referral to group art therapy plus standard care, compared with referral to an activity group plus standard care and standard care alone, among people with schizophrenia. DESIGN A three-arm, parallel group, single-blind, pragmatic, randomised controlled trial. Participants were randomised via an independent and remote telephone randomisation service using permuted blocks, stratified by study centre. SETTING Study participants were recruited from secondary care mental health and social services in four UK centres. PARTICIPANTS Potential participants were aged 18 years or over, had a clinical diagnosis of schizophrenia, confirmed by an examination of case notes, and provided written informed consent. We excluded those who were unable to speak sufficient English to complete the baseline assessment, those with severe cognitive impairment and those already receiving arts therapy. INTERVENTIONS Group art therapy was delivered by registered art therapists according to nationally agreed standards. Groups had up to eight members, lasted for 90 minutes and ran for 12 months. Members were given access to a range of art materials and encouraged to use these to express themselves freely. Activity groups were designed to control for the non-specific effects of group art therapy. Group facilitators offered various activities and encouraged participants to collectively select those they wanted to pursue. Standard care involved follow-up from secondary care mental health services and the option of referral to other services, except arts therapies, as required. MAIN OUTCOME MEASURES Our co-primary outcomes were global functioning (measured using the Global Assessment of Functioning Scale - GAF) and mental health symptoms (measured using the Positive and Negative Syndrome Scale - PANSS) at 24 months. The main secondary outcomes were level of group attendance, social functioning, well-being, health-related quality of life, service utilisation and other costs measured 12 and 24 months after randomisation. RESULTS Four hundred and seventeen people were recruited, of whom 355 (85%) were followed up at 2 years. Eighty-six (61%) of those randomised to art therapy and 73 (52%) of those randomised to activity groups attended at least one group. No differences in primary outcomes were found between the three study arms. The adjusted mean difference between art therapy and standard care at 24 months was -0.9 [95% confidence interval (CI) -3.8 to 2.1] on the GAF Scale and 0.7 (95% CI -3.1 to 4.6) on the PANSS Scale. Differences in secondary outcomes were not found, except that those referred to an activity group had fewer positive symptoms of schizophrenia at 24 months than those randomised to art therapy. Secondary analysis indicated that attendance at art therapy groups was not associated with improvements in global functioning or mental health. Although the total cost of the art therapy group was lower than the cost of the two comparison groups, referral to group art therapy did not appear to provide a cost-effective use of resources. CONCLUSIONS Referring people with established schizophrenia to group art therapy as delivered in this randomised trial does not appear to improve global functioning or mental health of patients or provide a more cost-effective use of resources than standard care alone.

Abstract
OBJECTIVE To examine the effectiveness and cost-effectiveness of group therapy for self harm in young people. DESIGN Two arm, single (assessor) blinded parallel randomised allocation trial of a group therapy intervention in addition to routine care, compared with routine care alone. Randomisation was by minimisation controlling for baseline frequency of self harm, presence of conduct disorder, depressive disorder, and severity of psychosocial stress. PARTICIPANTS Adolescents aged 12-17 years with at least two past episodes of self harm within the previous 12 months. Exclusion criteria were: not speaking English, low weight anorexia nervosa, acute psychosis, substantial learning difficulties (defined by need for specialist school), current containment in secure care. Setting Eight child and adolescent mental health services in the northwest UK. INTERVENTIONS Manual based developmental group therapy programme specifically designed for adolescents who harm themselves, with an acute phase over six weekly sessions followed by a booster phase of weekly groups as long as needed. Details of routine care were gathered from participating centres. MAIN OUTCOME MEASURES Primary outcome was frequency of subsequent repeated episodes of self harm. Secondary outcomes were severity of subsequent self harm, mood disorder, suicidal ideation, and global functioning. Total costs of health, social care, education, and criminal justice sector services, plus family related costs and productivity losses, were recorded. RESULTS 183 adolescents were allocated to each arm (total n = 366). Loss to follow-up was low (<4%). On all outcomes the trial cohort as a whole showed significant improvement from baseline to follow-up. On the primary outcome of frequency of self harm, proportional odds ratio of group therapy versus routine care adjusting for relevant baseline variables was 0.99 (95% confidence interval 0.68 to 1.44, P = 0.95) at 6 months and 0.88 (0.59 to 1.33, P = 0.52) at 1 year. For severity of subsequent self harm the equivalent odds ratios were 0.81 (0.54 to 1.20, P = 0.29) at 6 months and 0.94 (0.63 to 1.40, P = 0.75) at 1 year. Total 1 year costs were higher in the group therapy arm (£21,781) than for routine care (£15,372) but the difference was not significant (95% CI -1416 to 10782, P = 0.132). CONCLUSIONS The addition of this targeted group therapy programme did not improve self harm outcomes for adolescents who repeatedly self harmed, nor was there evidence of cost effectiveness. The outcomes to end point for the cohort as a whole were better than current clinical expectations. Trial registration ISRCTN 20496110.

Abstract
OBJECTIVE To evaluate the clinical effectiveness and cost-effectiveness of inpatient compared with outpatient treatment and general (routine) treatment in Child and Adolescent Mental Health Services (CAMHS) against specialist treatment for young people with anorexia nervosa. In addition, to determine young people's and their carers' satisfaction with these treatments. DESIGN A population-based, pragmatic randomised controlled trial (RCT) was carried out on young people age 12 to 18 presenting to community CAMHS with anorexia nervosa. SETTING Thirty-five English CAMHS in the north-west of England co-ordinated through specialist centres in Manchester and Liverpool. PARTICIPANTS Two hundred and fifteen young people (199 female) were identified, of whom 167 (mean age 14 years 11 months) were randomised and 48 were followed up as a preference group. INTERVENTIONS Randomised patients were allocated to either inpatient treatment in one of four units with considerable experience in the treatment of anorexia nervosa, a specialist outpatient programme delivered in one of two centres, or treatment as usual in general community CAMHS. The outpatient programmes spanned 6 months of treatment. The length of inpatient treatment was determined on a case-by-case basis on clinical need with outpatient follow-up to a minimum of 6 months. MAIN OUTCOME MEASURES Follow-up assessments were carried out at 1, 2 and 5 years. The primary outcome measure was the Morgan-Russell Average Outcome Scale (MRAOS) and associated categorical outcomes. Secondary outcome measures included physical measures of weight, height, body mass index (BMI) and % weight for height. Research ratings included the Health of the National Outcome Scale for Children and Adolescents (HoNOSCA). Self report measures comprised the user version of HoNOSCA (HoNOSCA-SR), the Eating Disorder Inventory 2 (EDI-2), the Family Assessment Device (FAD) and the recent Mood and Feelings Questionnaire (MFQ). Information on resource use was collected in interview at 1, 2 and 5 years using the Child and Adolescent Service Use Schedule (CA-SUS). Satisfaction was measured quantitatively using a questionnaire designed for the study and qualitative (free) responses on it. The questionnaire data were supplemented by qualitative analysis of user and carer focus groups. RESULTS Of the 167 patients randomised, 65% adhered to the allocated treatment. Adherence was lower for inpatient treatment (49%) than for general CAMHS (71%) or specialist outpatient treatment (77%) (p = 0.013). Every subject was traced at both 1 and 2 years, with the main outcome measure completed (through contact with the subject, family members or clinicians), by 94% at 1 year, 93% at 2 years, but only 47% at 5 years. A validated outcome category was assigned for 98% at 1 year, 96% at 2 years and 60% at 5 years. There was significant improvement in all groups at each time point, with the number achieving a good outcome being 19% at 1 year, 33% at 2 years and 64% (of those followed up) at 5 years. Analysis demonstrated no difference in treatment effectiveness of randomisation to inpatient compared with outpatient treatment, or, specialist over generalist treatment at any time point, when baseline characteristics were taken into account. Generalist CAMHS treatment was slightly more expensive over the first 2 years of the study, largely because greater numbers were subsequently admitted to hospital after the initial treatment phase. The specialist outpatient programme was the dominant treatment in terms of incremental cost-effectiveness. Specialist treatments had a higher probability of being more cost-effective than generalist treatments and outpatient treatment had a higher probability of being more cost-effective than inpatient care. Parental satisfaction with treatment was generally good, though better with specialist than generalist treatment. Young people's satisfaction was much more mixed, but again better with specialist treatment, including inpatient care. CONCLUSION Poor adherence to randomisation (despite initial consent to it), limits the assessment of the treatment effect of inpatient care. However, this study provides little support for lengthy inpatient psychiatric treatment on clinical or health economic grounds. These findings are broadly consistent with existing guidelines on the treatment of anorexia nervosa, which suggest that outpatient treatments should be offered to the majority, with inpatient treatment offered in rare cases, though our findings lend little support to a stepped-care approach in which inpatient care is offered to outpatient non-responders. Outpatient care, supported by brief (medical) inpatient management for correction of acute complications may be a preferable approach. The health economic analysis and user views both support NICE guidelines, which suggest that anorexia nervosa should be managed in specialist services that have experience and expertise in its management. Comprehensive general CAMHS might, however, be well placed to manage milder cases. Further research should focus on the specific components of outpatient psychological therapies. Although family-based treatments are well established, trials have not established their effectiveness compared with good-quality individual psychological therapies and the combination of individual and family approaches is untested. Further research is needed to establish which patients (if any) might respond to inpatient psychiatric treatment when unresponsive to outpatient care, the positive and negative components of it and the optimum length of stay.

Abstract
BACKGROUND Preimplantation genetic screening (PGS) has been used in an attempt to determine embryonic aneuploidy. Techniques that use new molecular methods to determine the karyotype of an embryo are expanding the scope of PGS. METHODS We introduce a new method for PGS, termed 'parental support', which leverages microarray measurements from parental DNA to 'clean' single-cell microarray measurements on embryonic cells and explicitly computes confidence in each copy number call. The method distinguishes mitotic and meiotic copy errors and determines parental source of aneuploidy. RESULTS Validation with 459 single cells of known karyotype indicated that per-cell false-positive and false-negative rates are roughly equivalent to the 'gold standard' metaphase karyotype. The majority of the cells were run in parallel with a clinical commercial PGS service. Computed confidences were conservative and roughly concordant with accuracy. To examine ploidy in human embryos, the method was then applied to 26 disaggregated, cryopreserved, cleavage-stage embryos for a total of 134 single blastomeres. Only 23.1% of the embryos were euploid, though 46.2% of embryos were mosaic euploid. Mosaicism affected 57.7% of the embryos. Counts of mitotic and meiotic errors were roughly equivalent. Maternal meiotic trisomy predominated over paternal trisomy, and maternal meiotic trisomies were negatively predictive of mosaic euploid embryos. CONCLUSIONS We have performed a major preclinical validation of a new method for PGS and found that the technology performs approximately as well as a metaphase karyotype. We also directly measured the mechanism of aneuploidy in cleavage-stage human embryos and found high rates and distinct patterns of mitotic and meiotic aneuploidy.

Abstract
OBJECTIVES To determine if, in the short term, depressed adolescents attending routine NHS Child and Adolescent Mental Health Services (CAMHS), and receiving ongoing active clinical care, treatment with selective serotonin reuptake inhibitors (SSRIs) plus cognitive behaviour therapy (CBT) compared with SSRI alone, results in better healthcare outcomes. DESIGN A pragmatic randomised controlled trial (RCT) was conducted on depressed adolescents attending CAMHS who had not responded to a psychosocial brief initial intervention (BII) prior to randomisation. SETTING Six English CAMHS participated in the study. PARTICIPANTS A total of 208 patients aged between 11 and 17 years were recruited and randomised. INTERVENTIONS All participants received active routine clinical care in a CAMHS outpatient setting and an SSRI and half were offered CBT. MAIN OUTCOME MEASURES The duration of the trial was a 12-week treatment phase, followed by a 16-week maintenance phase. Follow-up assessments were at 6, 12 and 28 weeks. The primary outcome measure was the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA). Secondary outcome measures were self-report depressive symptoms, interviewer-rated depressive signs and symptoms, interviewer-rated psychosocial impairment and clinical global impression of response to treatment. Information on resource use was collected in interview at baseline and at the 12- and 28-week follow-up assessments using the Child and Adolescent Service Use Schedule (CA-SUS). RESULTS Of the 208 patients randomised, 200 (96%) completed the trial to the primary end-point at 12 weeks. By the 28-week follow-up, 174 (84%) participants were re-evaluated. Overall, 193 (93%) participants had been assessed at one or more time points. Clinical characteristics indicated that the trial was conducted on a severely depressed group. There was significant recovery at all time points in both arms. The findings demonstrated no difference in treatment effectiveness for SSRI + CBT over SSRI only for the primary or secondary outcome measures at any time point. This lack of difference held when baseline and treatment characteristics where taken into account (age, sex, severity, co-morbid characteristics, quality and quantity of CBT treatment, number of clinic attendances). The SSRI + CBT group was somewhat more expensive over the 28 weeks than the SSRI-only group (p=0.057) and no more cost-effective. Over the trial period there was on average a decrease in suicidal thoughts and self-harm compared with levels recorded at baseline. There was no significant increase in disinhibition, irritability and violence compared with levels at baseline. Around 20% (n=40) of patients in the trial were non-responders. Of these, 17 (43%) showed no improvement by 28 weeks and 23 (57%) were considered minimally (n=10) or moderately to severely worse (n=13). CONCLUSIONS For moderately to severely depressed adolescents who are non-responsive to a BII, the addition of CBT to fluoxetine plus routine clinical care does not improve outcome or confer protective effects against adverse events and is not cost-effective. SSRIs (mostly fluoxetine) are not likely to result in harmful adverse effects. The findings are broadly consistent with existing guidelines on the treatment of moderate to severe depression. Modification is advised for those presenting with moderate (6-8 symptoms) to severe depressions (>8 symptoms) and in those with either overt suicidal risk and/or high levels of personal impairment. In such cases, the time allowed for response to psychosocial interventions should be no more than 2-4 weeks, after which fluoxetine should be prescribed. Further research should focus on evaluating the efficacy of specific psychological treatments against brief psychological intervention, determining the characteristics of patients with severe depression who are non-responsive to fluoxetine, relapse prevention in severe depression and improving tools for determining treatment responders and non-responders.

Abstract
OBJECTIVES To compare the health-related quality of life among adult males affected with mild hemophilia A due to the same mutation (Val2016ala) to that of unaffected age and sex matched controls from the same general population. METHODS The Short-Form 36 (SF-36) and Health Assessment Questionnaire (HAQ) were used to measure health-related quality of life and physical function. Other measures included bleeding history, a measure of joint damage, body mass index, age, and viral infection status. Cross-sectional data were collected through research clinics and a retrospective chart audit over a two-year period. RESULTS AND CONCLUSIONS The study included 47 affected males and 33 controls. The affected males had a higher level of co-morbidity, prior bleeding, and existing joint damage than controls. With the exception of the social function and health transition scales, mean scores for each of the SF-36 domains were worse among affected males. Mean differences were more than a clinically important five points in five of eight domains, with the general health scale showing more than a 10-point difference. Despite the degree of difference noted, only two of the differences were statistically significant (general health and role emotional scales) because of the small sample size and considerable individual variation in SF-36 scale scores. Multiple regression analyses suggested existing joint damage and presence of heart disease as the strongest associates of lower physical health-related quality of life. Joint damage in turn was partly related to prior hemarthroses. Compared to the Canadian population, affected males had lower scores in six out of eight SF-36 domains as well as the physical component summary score. There were no significant differences found in the HAQ scores between the two groups. So-called mild hemophilia A was associated with a negative effect on physical health-related quality of life, contributed to by joint damage as a result of prior bleeding.

Abstract
BACKGROUND Major depression is an important and costly problem among adolescents, yet evidence to support the provision of cost-effective treatments is lacking. AIMS To assess the short-term cost-effectiveness of combined selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioural therapy (CBT) together with clinical care compared with SSRIs and clinical care alone in adolescents with major depression. METHOD Pragmatic randomised controlled trial in the UK. Outcomes and costs were assessed at baseline, 12 and 28 weeks. RESULTS The trial comprised 208 adolescents, aged 11-17 years, with major or probable major depression who had not responded to a brief initial psychosocial intervention. There were no significant differences in outcome between the groups with and without CBT. Costs were higher in the group with CBT, although not significantly so (P=0.057). Cost-effectiveness analysis and exploration of the associated uncertainty suggest there is less than a 30% probability that CBT plus SSRIs is more cost-effective than SSRIs alone. CONCLUSIONS A combination of CBT plus SSRIs is not more cost-effective in the short-term than SSRIs alone for treating adolescents with major depression in receipt of routine specialist clinical care.

Abstract
A validated, highly sensitive and selective high-pressure liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the quantitative determination of quetiapine (QUE) in human Na2EDTA plasma with mass spectrometry (MS) detection. Clozapine (CLO) was employed as an internal standard. Samples were extracted using solid phase extraction (SPE). Oasis HLB cartridges and the concentration of quetiapine was determined by isocratic HPLC-MS/MS. The SRM mode was used for MS/MS detection. The method was validated over a concentration range of 1.0-382.2 ng/mL. Inter- and intra-day precision and accuracy of the proposed method were characterized by relative standard deviation (R.S.D.) and the percentage of deviation, respectively; both were lower than 8%. The developed method was employed in the pharmacokinetic study of quetiapine.

Abstract
The 1H(e,e'pi+)n cross section was measured at four-momentum transfers of Q2=1.60 and 2.45 GeV2 at an invariant mass of the photon nucleon system of W=2.22 GeV. The charged pion form factor (F(pi)) was extracted from the data by comparing the separated longitudinal pion electroproduction cross section to a Regge model prediction in which F(pi) is a free parameter. The results indicate that the pion form factor deviates from the charge-radius constrained monopole form at these values of Q2 by one sigma, but is still far from its perturbative quantum chromodynamics prediction.

Abstract
Cholesterol-reducing statin drugs are the most frequently prescribed agents for reducing morbidity and mortality related to coronary heart disease. In this publication a validated, highly sensitive, and selective isocratic HPLC method is reported for quantitative determination of the major statin drug atorvastatin (ATV) and its metabolite 2-hydroxyatorvastatin (HATV). Detection was performed with an electrospray ionization triple-quadrupole mass spectrometer equipped with an ESI interface operating in positive-ionization mode. Multiple reaction monitoring (MRM) was used for MS-MS detection. The calibration plot was linear in the concentration range 0.10-40.00 ng mL(-1) for both ATV and HATV. Inter-day and intra-day precision and accuracy of the proposed method were characterized by measurement of relative standard deviation (RSD) and percentage deviation, respectively; both were less than 8% for both analytes. The limit of quantitation was 0.02 ng mL(-1) for ATV and 0.07 ng mL(-1) for HATV. The method was used for pharmacokinetic study of ATV and HATV. Pharmacokinetic data for all analytes are also reported.

Abstract
Due to high incidence and quality-of-life impact, upper respiratory infection substantially impacts on population health. To test or compare treatment effectiveness, a well-designed and validated illness-specific quality-of-life instrument is needed. Data reported in the current study were obtained from a trial testing echinacea for induced rhinovirus infection. Laboratory-assessed biomarkers included interleukin (IL)-8, nasal neutrophil count (polymorphonuclear neutrophils (PMN)), mucus weight, viral titre and seroconversion. The questionnaires used included the general health short form (SF)-8 (24-h recall version), the eight-item Jackson cold scale, and the 44-item Wisconsin Upper Respiratory Symptom Survey (WURSS). In total, 399 participants were inoculated with rhinovirus and monitored over 2,088 person-days. Statistically significant associations were found among nearly all variables. Between-questionnaire correlations were: WURSS-Jackson = 0.81; WURSS-SF-8 = 0.62; and Jackson-SF-8 = 0.60. Correlations with laboratory values were as follows: WURSS-mucus weight = 0.53; Jackson-mucus weight = 0.55; WURSS-viral titre = 0.37; Jackson-viral titre = 0.46; WURSS-IL-8 = 0.31; Jackson-IL-8 = 0.36; WURSS-PMN = 0.31; and Jackson-PMN = 0.28. Neither WURSS nor Jackson yielded satisfactory cut-off scores for diagnosis of infection. Symptomatic and biological outcomes of upper respiratory infection are highly variable, with only modest associations. While Wisconsin Upper Respiratory Symptom Survey and Jackson questionnaires both correlate with biomarkers, neither is a good predictor of induced infection. The inclusion of functional and quality-of-life items in the Wisconsin Upper Respiratory Symptom Survey does not significantly decrease the strength of association with laboratory-assessed biomarkers.
