Two crystal structures of chalcones, or 1,3-diarylprop-2-en-1-ones, are presented; both contain a p-methyl substitution on the 3-Ring, but differ with respect to the m-substitution on the 1-Ring. Their systematic names are (2E)-3-(4-methylphenyl)-1-(3-{[(4-methylphenyl)methylidene]amino}phenyl)prop-2-en-1-one (C24H21NO) and N-{3-[(2E)-3-(4-methylphenyl)prop-2-enoyl]phenyl}acetamide (C18H17NO2), which are abbreviated as 3′-(N=CHC6H4-p-CH3)-4-methylchalcone and 3′-(NHCOCH3)-4-methylchalcone, respectively. Both chalcones represent the first reported acetamide-substituted and imino-substituted chalcone crystal structures, adding to the robust library of chalcone structures within the Cambridge Structural Database. The crystal structure of 3′-(N=CHC6H4-p-CH3)-4-methylchalcone exhibits close contacts between the enone O atom and the substituent arene ring, in addition to C...C interactions between the substituent arene rings. The structure of 3′-(NHCOCH3)-4-methylchalcone exhibits a unique interaction between the enone O atom and the 1-Ring substituent, contributing to its antiparallel crystal packing. In addition, both structures exhibit π-stacking, which occurs between the 1-Ring and R-Ring for 3′-(N=CHC6H4-p-CH3)-4-methylchalcone, and between the 1-Ring and 3-Ring for 3′-(NHCOCH3)-4-methylchalcone.

Background Humans display an age-related decline in cerebral blood flow and increase in blood pressure (BP), but changes in the underlying control mechanisms across the lifespan are less well understood. We aimed to; (1) examine the impact of age, sex, cardiovascular disease (CVD) risk, and cardio-respiratory fitness on dynamic cerebral autoregulation and cardiac baroreflex sensitivity, and (2) explore the relationships between dynamic cerebral autoregulation (dCA) and cardiac baroreflex sensitivity (cBRS). Methods 206 participants aged 18–70 years were stratified into age categories. Cerebral blood flow velocity was measured using transcranial Doppler ultrasound. Repeated squat-stand manoeuvres were performed (0.10 Hz), and transfer function analysis was used to assess dCA and cBRS. Multivariable linear regression was used to examine the influence of age, sex, CVD risk, and cardio-respiratory fitness on dCA and cBRS. Linear models determined the relationship between dCA and cBRS. Results Age, sex, CVD risk, and cardio-respiratory fitness did not impact dCA normalised gain, phase, or coherence with minimal change in all models (P > 0.05). cBRS gain was attenuated with age when adjusted for sex and CVD risk (young–older; β = − 2.86 P β = − 0.44, P Conclusion Ageing was associated with a decreased cBRS, but dCA appears to remain unchanged. Additionally, our data suggest that sex, CVD risk, and cardio-respiratory fitness have little effect.

Significance IgG antibodies are a key component of adaptive humoral immunity but can cause organ damage if they bind self-antigen, as occurs in the autoimmune disease systemic lupus erythematosus (SLE). Many of the proinflammatory effects of IgG are mediated by ligating Fcγ receptors (FcγRs) expressed by tissue-resident leukocytes such as macrophages. One of the most serious complications of SLE is kidney inflammation: lupus nephritis. Here we show that IgG ligation of FcγRs on macrophages in the kidney leads to a change in their metabolism, resulting in a switch toward glycolysis. Administration of a glycolysis inhibitor attenuated IgG-associated kidney macrophage activation, proinflammatory cytokine secretion, and kidney inflammation. Therefore, manipulating macrophage metabolism may be a useful therapeutic strategy in lupus nephritis., IgG antibodies cause inflammation and organ damage in autoimmune diseases such as systemic lupus erythematosus (SLE). We investigated the metabolic profile of macrophages isolated from inflamed tissues in immune complex (IC)-associated diseases, including SLE and rheumatoid arthritis, and following IgG Fcγ receptor cross-linking. We found that human and mouse macrophages undergo a switch to glycolysis in response to IgG IC stimulation, mirroring macrophage metabolic changes in inflamed tissue in vivo. This metabolic reprogramming was required to generate a number of proinflammatory mediators, including IL-1β, and was dependent on mTOR and hypoxia-inducible factor (HIF)1α. Inhibition of glycolysis, or genetic depletion of HIF1α, attenuated IgG IC-induced activation of macrophages in vitro, including primary human kidney macrophages. In vivo, glycolysis inhibition led to a reduction in kidney macrophage IL-1β and reduced neutrophil recruitment in a murine model of antibody-mediated nephritis. Together, our data reveal the molecular mechanisms underpinning FcγR-mediated metabolic reprogramming in macrophages and suggest a therapeutic strategy for autoantibody-induced inflammation, including lupus nephritis.

The structures of three iodochalcones, functionalized with fluorine or a nitro group, have been investigated to explore the impact of different molecular electrostatic distributions on the halogen bonding within each crystal structure. The strongly withdrawing nitro group presented a switch of the halogen bond from a lateral to a linear motif. Surprisingly, this appears to be influenced by a net positive shift in charge distribution around the lateral edges of the σ-hole, making the lateral I...I bonding motif less preferable. A channel of amphoteric I...I type II halogen bonds is observed for a chalcone molecule, which was not previously reported in chalcones, alongside an example of the common synthon involving extended linear chains of I...O2N donor–acceptor halogen bonds. This work shows that halogenated chalcones may be an interesting target for developing halogen bonding as a significant tool within crystal engineering, a thus far underexplored area for this common structural motif.

IgG antibodies form immune complexes (IC) that propagate inflammation and tissue damage in autoimmune diseases such as systemic lupus erythematosus. IgG IC engage Fcγ receptors (FcγR) on mononuclear phagocytes (MNP), leading to widespread changes in gene expression that mediate antibody effector function. Bromodomain and extra-terminal domain (BET) proteins are involved in governing gene transcription. We investigated the capacity of BET protein inhibitors (iBET) to alter IgG FcγR-mediated MNP activation. We found that iBET dampened IgG IC-induced pro-inflammatory gene expression and decreased activating FcγR expression on MNPs, reducing their ability to respond to IgG IC. Despite FcγR downregulation, iBET-treated macrophages demonstrated increased phagocytosis of protein antigen, IgG IC, and apoptotic cells. iBET also altered cell morphology, generating more amoeboid MNPs with reduced adhesion. iBET treatment impaired chemotaxis towards a CCL19 gradient in IC-stimulated dendritic cells (DC) in vitro, and inhibited IC-induced DC migration to draining lymph nodes in vivo, in a DC-intrinsic manner. Altogether, our data show that iBET modulates FcγR-mediated MNP activation and migration, revealing the therapeutic potential of BET protein inhibition in antibody-mediated diseases.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections have a devastating effect on patients receiving hemodialysis. To what extent infection-induced antibody responses are maintained, or protective, is unknown. This study describes the evolution of antibodies against the SARS-CoV-2 spike protein in a cohort of 990 patients on hemodialysis. During the first wave of the pandemic, 26% of patients had developed antispike SARS-CoV-2 antibodies. Fewer PCR-confirmed second-wave infections were observed in patients with pre-existing antibodies (4.2%) than those without antibodies (11.4%). This study shows that SARS-CoV-2 antibodies in patients on hemodialysis are well maintained and associate with reduced risk of subsequent SARS-CoV-2 infection.

Aims: BEAWARE investigated the pattern of first-line bevacizumab early interruption in the Italian real-world setting of metastatic colorectal cancer. Methods: A total of 386 patients were followed for 15 months after first-line chemotherapy + bevacizumab start. The rate of bevacizumab interruption for progression or adverse drug reactions (ADRs) constituted the primary endpoint. Results: A total of 78.2% of patients interrupted bevacizumab: 56.6% for progression, 7.3% for ADRs, and 36.1% for other reasons. Median treatment duration was 6.7, 2.5, and 4.6 months, respectively. Median progression-free survival was 10.3 months; however, 35.8% of patients were not progressed and were thus censored at the data cutoff of 15 months, while 21.8% were still receiving bevacizumab. Patients discontinuing for progression/ADRs more frequently had metastases in >1 site ( p = .0001), and a shorter median progression-free survival (6.9 vs 13.9 months, p < .0001). Conclusions: In Italy, first-line bevacizumab is interrupted mainly for progression, only 7.3% due to adverse events, and about one third of cases for other reasons. In clinical practice, the attitude to treat until progression as per guidelines might be implemented. ClinicalTrials.gov Identifier: NCT01609075

Background Older adults, including those with long-term conditions (LTCs), are vulnerable to social isolation. They are likely to have become more socially isolated during the Coronavirus Disease 2019 (COVID-19) pandemic, often due to advice to “shield” to protect them from infection. This places them at particular risk of depression and loneliness. There is a need for brief scalable psychosocial interventions to mitigate the psychological impacts of social isolation. Behavioural activation (BA) is a credible candidate intervention, but a trial is needed. Methods and findings We undertook an external pilot parallel randomised trial (ISRCTN94091479) designed to test recruitment, retention and engagement with, and the acceptability and preliminary effects of the intervention. Participants aged ≥65 years with 2 or more LTCs were recruited in primary care and randomised by computer and with concealed allocation between June and October 2020. BA was offered to intervention participants (n = 47), and control participants received usual primary care (n = 49). Assessment of outcome was made blind to treatment allocation. The primary outcome was depression severity (measured using the Patient Health Questionnaire 9 (PHQ-9)). We also measured health-related quality of life (measured by the Short Form (SF)-12v2 mental component scale (MCS) and physical component scale (PCS)), anxiety (measured by the Generalised Anxiety Disorder 7 (GAD-7)), perceived social and emotional loneliness (measured by the De Jong Gierveld Scale: 11-item loneliness scale). Outcome was measured at 1 and 3 months. The mean age of participants was aged 74 years (standard deviation (SD) 5.5) and they were mostly White (n = 92, 95.8%), and approximately two-thirds of the sample were female (n = 59, 61.5%). Remote recruitment was possible, and 45/47 (95.7%) randomised to the intervention completed 1 or more sessions (median 6 sessions) out of 8. A total of 90 (93.8%) completed the 1-month follow-up, and 86 (89.6%) completed the 3-month follow-up, with similar rates for control (1 month: 45/49 and 3 months 44/49) and intervention (1 month: 45/47and 3 months: 42/47) follow-up. Between-group comparisons were made using a confidence interval (CI) approach, and by adjusting for the covariate of interest at baseline. At 1 month (the primary clinical outcome point), the median number of completed sessions for people receiving the BA intervention was 3, and almost all participants were still receiving the BA intervention. The between-group comparison for the primary clinical outcome at 1 month was an adjusted between-group mean difference of −0.50 PHQ-9 points (95% CI −2.01 to 1.01), but only a small number of participants had completed the intervention at this point. At 3 months, the PHQ-9 adjusted mean difference (AMD) was 0.19 (95% CI −1.36 to 1.75). When we examined loneliness, the adjusted between-group difference in the De Jong Gierveld Loneliness Scale at 1 month was 0.28 (95% CI −0.51 to 1.06) and at 3 months −0.87 (95% CI −1.56 to −0.18), suggesting evidence of benefit of the intervention at this time point. For anxiety, the GAD adjusted between-group difference at 1 month was 0.20 (−1.33, 1.73) and at 3 months 0.31 (−1.08, 1.70). For the SF-12 (physical component score), the adjusted between-group difference at 1 month was 0.34 (−4.17, 4.85) and at 3 months 0.11 (−4.46, 4.67). For the SF-12 (mental component score), the adjusted between-group difference at 1 month was 1.91 (−2.64, 5.15) and at 3 months 1.26 (−2.64, 5.15). Participants who withdrew had minimal depressive symptoms at entry. There were no adverse events. The Behavioural Activation in Social Isolation (BASIL) study had 2 main limitations. First, we found that the intervention was still being delivered at the prespecified primary outcome point, and this fed into the design of the main trial where a primary outcome of 3 months is now collected. Second, this was a pilot trial and was not designed to test between-group differences with high levels of statistical power. Type 2 errors are likely to have occurred, and a larger trial is now underway to test for robust effects and replicate signals of effectiveness in important secondary outcomes such as loneliness. Conclusions In this study, we observed that BA is a credible intervention to mitigate the psychological impacts of COVID-19 isolation for older adults. We demonstrated that it is feasible to undertake a trial of BA. The intervention can be delivered remotely and at scale, but should be reserved for older adults with evidence of depressive symptoms. The significant reduction in loneliness is unlikely to be a chance finding, and replication will be explored in a fully powered randomised controlled trial (RCT). Trial registration ISRCTN94091479., In a pilot randomised controlled trial, Simon Gilbody and colleagues present preliminary findings from a telephone delivered intervention (behavioural activation) designed to prevent depression and loneliness among socially isolated older people with long term conditions., Author summary Why was this study done? Older people with long-term conditions (LTCs) have been impacted by the Coronavirus Disease 2019 (COVID-19) pandemic and its restrictions. They are at risk of social isolation and, in turn, this could cause depression and loneliness, which are bad for health. Psychological approaches, such as behavioural activation (BA), could be helpful. A fair test is needed to demonstrate if BA can prevent the onset of depression and loneliness, but before we can do this, it is important to test this out in a smaller scale study. What did the researchers do and find? We designed a brief telephone-delivered intervention based on sound psychological principles known as BA. Here, we present the result of a pilot trial. We demonstrate that the intervention is acceptable to older people who are socially isolated as a consequence of the pandemic. We tested whether it is possible to collect important outcomes in the short term. There was some preliminary evidence that levels of loneliness were reduced at 3 months when BA is offered. What do these findings mean? This was a smaller scale pilot study, and our procedures worked well. If BA is shown to work, then this will be useful for policymakers in offering support to people who are socially isolated. This will also be useful once the COVID-19 pandemic has passed, since loneliness is common in older populations, and effective scalable solutions will be needed even after COVID-19. The Behavioural Activation in Social Isolation (BASIL) pilot trial was not designed to test differences in outcomes between the 2 groups. We will now test this in a much larger study.

The ocean and any form of bodies of water must be protected and secure from any intruders and to monitor our ocean, technology must be used and integrated for more efficient monitoring. Automatic boat detection plays an important role in maritime surveillance. However, the maritime environment represents lots of challenges such as the wave of water, boat movements, and weather condition. This paper presents a method for detecting moving boats from a sequence of images using a deep learning approach. In this study, the researchers proposed a detection system for the boats in the ocean using optical aerial images. The researchers conducted testing and the results were favorable. Upon testing the researchers obtained a 90% accuracy of detection of the ship in the ocean using the single images, video feeds, and live feeds. The experiments show promising results.

Nitrous oxide at 50% inhaled concentration has been shown to improve depressive symptoms in patients with treatment-resistant major depression (TRMD). Whether a lower concentration of 25% nitrous oxide provides similar efficacy and persistence of antidepressant effects while reducing the risk of adverse side effects is unknown. In this phase 2 clinical trial (NCT03283670), 24 patients with severe TRMD were randomly assigned in a crossover fashion to three treatments consisting of a single 1-hour inhalation with (i) 50% nitrous oxide, (ii) 25% nitrous oxide, or (iii) placebo (air/oxygen). The primary outcome was the change on the Hamilton Depression Rating Scale (HDRS-21). Whereas nitrous oxide significantly improved depressive symptoms versus placebo (P = 0.01), there was no difference between 25 and 50% nitrous oxide (P = 0.58). The estimated differences between 25% and placebo were -0.75 points on the HDRS-21 at 2 hours (P = 0.73), -1.41 points at 24 hours (P = 0.52), -4.35 points at week 1 (P = 0.05), and -5.19 points at week 2 (P = 0.02), and the estimated differences between 50% and placebo were -0.87 points at 2 hours (P = 0.69), -1.93 points at 24 hours (P = 0.37), -2.44 points at week 1 (P = 0.25), and -7.00 points at week 2 (P = 0.001). Adverse events declined substantially with dose (P < 0.001). These results suggest that 25% nitrous oxide has comparable efficacy to 50% nitrous oxide in improving TRMD but with a markedly lower rate of adverse effects.

The Coordinated Ionospheric Reconstruction Cubesat Experiment (CIRCE) is a collaborative space mission between the UK Defence Science and Technology Laboratory (Dstl), and the US Naval Research Laboratory (NRL) in developing small satellite ionospheric physics capability. CIRCE will characterise space weather effects on a regional scale in the ionosphere/thermosphere system. Properly characterising the dynamic ionosphere is important for a wide range of both civil and defence applications such as GPS, communications, and sensing technology. Consisting of two near-identical 6U (2x3U) CubeSat buses, the CIRCE nanosatellites will fly in a lead-follow tandem configuration in co-planar near-polar orbits at 500km altitude. Provided by Blue Canyon Technologies (BCT), the two buses will use differential drag to achieve and maintain an in-track separation of between 250 and 500km, allowing short time-scale dynamics to be observed in-situ. These nanosatellites each carry a complement of 5 individual scientific instruments, contributed from academic, industrial, and government partners across the UK and US. Scheduled to launch in 2021 via the US Department of Defence Space Test Program, the two CIRCE satellites will provide observations to enable a greater understanding of the driving processes of geophysical phenomena in the ionosphere/thermosphere system, distributed across a wide range of latitudes, and altitudes, as the mission progresses.

This work has the aim of reducing these differences in 4 use cases: Women as users of railway stations, bike sharing and autonomous vehicles and women as jobholders.

Smoking cessation treatment outcomes may be heavily influenced by genetic variations among smokers. Therefore, identifying specific variants that affect response to different pharmacotherapies is of major interest to the field. In the current study, we systematically review all studies published in or after the year 1990 which examined one or more gene–drug interactions for smoking cessation treatment. Out of 644 citations, 46 articles met the inclusion criteria for the systematic review. We summarize evidence on several genetic polymorphisms (CHRNA5-A3-B4, CYP2A6, DBH, CHRNA4, COMT, DRD2, DRD4 and CYP2B6) and their potential moderating pharamacotherarpy effects on patient cessation efficacy rates. These findings are promising and call for further research to demonstrate the effectiveness of genetic testing in personalizing treatment decision-making and improving outcome.

An estimated 30% of patients accessing community weight management services experience symptoms of binge eating disorder (BED). Guided self-help (GSH) is the recommended first line of treatment for BED. This study is a preliminary investigation into the effectiveness of GSH delivered by dietitians for patients with binge eating within a weight management service and a consideration of the association between wellbeing, therapeutic relationship and outcomes. The study was conducted as a single group, pre- and post-intervention study with 24 patients reporting symptoms of binge eating who completed the self-help manual with guidance from a trained community dietitian. Primary outcomes were eating disorder psychopathology and behaviours (Eating Disorder Evaluation Questionnaire), depression and anxiety. Principle results showed a significant reduction on all subscales of eating disorder psychopathology, anxiety and depression. There was a reduction in loss of control over eating but the 40% reduction in binge episodes was not statistically significant. Mid-treatment sessional ratings were positively associated with outcome. In conclusion, the GSH intervention was appropriate for dietitian delivery to patients with obesity and binge eating behaviour. This research indicates potential for other dietetic-led weight management services to deliver such interventions and support patients with binge eating accessing their service.

Summary Background B cells produce alloantibodies and activate alloreactive T cells, negatively affecting kidney transplant survival. By contrast, regulatory B cells are associated with transplant tolerance. Immunotherapies are needed that inhibit B-cell effector function, including antibody secretion, while sparing regulators and minimising infection risk. B lymphocyte stimulator (BLyS) is a cytokine that promotes B-cell activation and has not previously been targeted in kidney transplant recipients. We aimed to determine the safety and activity of an anti-BLyS antibody, belimumab, in addition to standard-of-care immunosuppression in adult kidney transplant recipients. We used an experimental medicine study design with multiple secondary and exploratory endpoints to gain further insight into the effect of belimumab on the generation of de-novo IgG and on the regulatory B-cell compartment. Methods We undertook a double-blind, randomised, placebo-controlled phase 2 trial of belimumab, in addition to standard-of-care immunosuppression (basiliximab, mycophenolate mofetil, tacrolimus, and prednisolone) at two centres, Addenbrooke's Hospital, Cambridge, UK, and Guy's and St Thomas' Hospital, London, UK. Participants were eligible if they were aged 18–75 years and receiving a kidney transplant and were planned to receive standard-of-care immunosuppression. Participants were randomly assigned (1:1) to receive either intravenous belimumab 10 mg per kg bodyweight or placebo, given at day 0, 14, and 28, and then every 4 weeks for a total of seven infusions. The co-primary endpoints were safety and change in the concentration of naive B cells from baseline to week 24, both of which were analysed in all patients who received a transplant and at least one dose of drug or placebo (the modified intention-to-treat [mITT] population). This trial has been completed and is registered with ClinicalTrials.gov, NCT01536379, and EudraCT, 2011–006215–56. Findings Between Sept 13, 2013, and Feb 8, 2015, of 303 patients assessed for eligibility, 28 kidney transplant recipients were randomly assigned to receive belimumab (n=14) or placebo (n=14). 25 patients (12 [86%] patients assigned to the belimumab group and 13 [93%] patients assigned to the placebo group) received a transplant and were included in the mITT population. We observed similar proportions of adverse events in the belimumab and placebo groups, including serious infections (one [8%] of 12 in the belimumab group and five [38%] of 13 in the placebo group during the 6-month on-treatment phase; and none in the belimumab group and two [15%] in the placebo group during the 6-month follow-up). In the on-treatment phase, one patient in the placebo group died because of fatal myocardial infarction and acute cardiac failure. The co-primary endpoint of a reduction in naive B cells from baseline to week 24 was not met. Treatment with belimumab did not significantly reduce the number of naive B cells from baseline to week 24 (adjusted mean difference between the belimumab and placebo treatment groups −34·4 cells per μL, 95% CI −109·5 to 40·7). Interpretation Belimumab might be a useful adjunct to standard-of-care immunosuppression in renal transplantation, with no major increased risk of infection and potential beneficial effects on humoral alloimmunity.

Instructional videos have been prepared using Adobe Captivate software to create animated tutorials to capture instrument and molecular modeling software simulations and to allow for increased independent hands-on instrument use by students and faster training for instructors and teaching assistants. The videos are available on YouTube and can be viewed prior to or synchronously as students are acquiring an IR spectrum, processing an 1H NMR spectrum, or performing specific calculations using GaussView. Student surveys indicate preference for the animated tutorials over conventional paper instructions and general favorability of the videos.

Background Evidence-based self-help is a recommended first stage of treatment for mild–moderate eating disorders. The provision of guidance enhances outcome. The literature evaluating exclusively ‘guided’ self-help (GSH) has not been systematically reviewed. Methods The aim was to establish the effectiveness of GSH for reducing global eating disorder psychopathology and abstinence from binge eating, compared with controls. Results were pooled using random effects meta-analysis and heterogeneity explored using metaregression. Results Thirty randomised controlled trials met the inclusion criteria. Results showed an overall effect of GSH on global eating disorder psychopathology (−0.46) and binge abstinence (−0.20). There was strong evidence for an association between diagnosis of binge eating disorder and binge abstinence. Discussion Current interventions need to be adapted to address features other than binge eating. Further research is required to help us understand the effectiveness of GSH in children and young people, invariably high dropout rates and how technology can enhance interventions.

It is well known that recruitment into general practice (GP) is low, particularly in deprived areas. Undergraduate medical students are encouraged to learn about health inequalities.However, teaching on this area has been perceived by some as uninspiring. Innovative teaching opportunities can engage students but more research is needed regarding exposure to deprived inner-city settings. Street Medics is an extra-curricular, educational initiative which enables students to join GPs doing street-outreach work. The aim of the study was to understand what motivates undergraduate medical students to engage with Street Medics and the impact of the experience. Focus group data were collected and thematically analysed. Motivating factor themes: appetite to explore; previous exposure including observation of perceived sub-optimal care to marginalised patients; perceived lack of exposure personally and in undergraduate teaching. Experience and impact themes: increased understanding of social determinants of health; change in perception; influence on career intentions; desire to incorporate into curriculum. Opportunities like Street Medics can supplement the undergraduate curriculum and not only challenge students' perceptions of marginalised patients but also ignite their enthusiasm for pursuing GP. By understanding the factors driving students' engagement in innovative educational opportunities, effective methods can be shared across undergraduate courses.

Cat ownership is increasing globally, representing a growing threat to urban wildlife. Although some cities have policies and strategies for managing owned cats, the companionship value placed on cats makes such management contentious. Prioritizing cat management in urban residential zones adjacent to large significant ecological areas (SEAs; areas designated on the basis of representativeness, threat status or rarity, diversity, connectedness, or uniqueness) could maximize return on management effort. Residents in these areas may place a relatively higher value on nature than residents in suburbs with minimal or no SEAs, and therefore may be comparatively more likely to perceive cats' wildlife impacts as important. We used a quantitative survey to compare SEA and non-SEA suburbs' residents' attitudes towards cat impacts and management in Tāmaki Makaurau-Auckland, Aotearoa-New Zealand. Participants were asked to rate the importance of different feral and owned cat impacts, the importance of feral-cat control in different locations, and various ownership behaviors in terms of acceptability and best practice. SEA suburb residents placed more importance on wildlife predation impacts of feral cats and were more likely to regard 24-h cat confinement as best practice than non-SEA suburb residents. However, we also found that cat ownership and youth were negatively associated with perception of cat impacts, and owners were less likely to accept belled collars and cat confinement than nonowners. Therefore, although targeting SEA adjacent areas for cat management holds promise for reducing resident contention, proximity to such areas is a relatively minor influence for cat owners.

BACKGROUND Major depressive disorder (MDD) is highly recurrent and has a significant disease burden. Although the effectiveness of internet-based interventions has been established for the treatment of acute MDD, little is known about their cost effectiveness, especially in recurrent MDD. OBJECTIVES Our aim was to evaluate the cost effectiveness and cost utility of an internet-based relapse prevention program (mobile cognitive therapy, M-CT). METHODS The economic evaluation was performed alongside a single-blind parallel group randomized controlled trial. Participants were recruited via media, general practitioners, and mental health care institutions. In total, 288 remitted individuals with a history of recurrent depression were eligible, of whom 264 were randomly allocated to M-CT with minimal therapist support added to treatment as usual (TAU) or TAU alone. M-CT comprised 8 online lessons, and participants were advised to complete 1 lesson per week. The economic evaluation was performed from a societal perspective with a 24-month time horizon. The health outcomes were number of depression-free days according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, (DSM-IV) criteria assessed with the Structured Clinical Interview for DSM-IV axis I disorders by blinded interviewers after 3, 12, and 24 months. Quality-adjusted life years (QALYs) were self-assessed with the three level version of the EuroQol Five Dimensional Questionnaire (EQ-5D-3L). Costs were assessed with the Trimbos and Institute for Medical Technology Assessment Questionnaire on Costs Associated with Psychiatric Illness (TiC-P). Incremental cost-effectiveness ratios were calculated and cost-effectiveness planes and cost-effectiveness acceptability curves were displayed to assess the probability that M-CT is cost effective compared to TAU. RESULTS Mean total costs over 24 months were €8298 (US $9415) for M-CT and €7296 (US $8278) for TAU. No statistically significant differences were found between M-CT and TAU regarding depression-free days and QALYs (P=.37 and P=.92, respectively). The incremental costs were €179 (US $203) per depression-free day and €230,816 (US $261,875) per QALY. The cost-effectiveness acceptability curves suggested that for depression-free days, high investments have to be made to reach an acceptable probability that M-CT is cost effective compared to TAU. Regarding QALYs, considerable investments have to be made but the probability that M-CT is cost effective compared to TAU does not rise above 40%. CONCLUSIONS The results suggest that adding M-CT to TAU is not effective and cost effective compared to TAU alone. Adherence rates were similar to other studies and therefore do not explain this finding. The participants scarcely booked additional therapist support, resulting in 17.3 minutes of mean total therapist support. More studies are needed to examine the cost effectiveness of internet-based interventions with respect to long-term outcomes and the role and optimal dosage of therapist support. Overall, more research is needed on scalable and cost-effective interventions that can reduce the burden of recurrent MDD.

Symptoms of distress during pregnancy are common and often go unnoticed. There is a well-established relation between life events and depression. The current study aims to explore the association between life events and difficulties, and symptoms of emotional and somatic distress during pregnancy in White and South Asian women in the UK.100 pregnant women attending routine antenatal appointments were interviewed using the Life Events and Difficulties Schedule (LEDS). We investigated the frequency and type of events experienced in the year prior to conception and during pregnancy, as predictors for somatic and emotional distress, measured using the GHQ-28.Non-severe stressors accounted for over 90 % of those reported, half of which (43-53 %) were health and reproduction-related. Somatic symptoms were associated with the number of non-severe events, and number of children and emotional symptoms were associated with non-marked difficulties. There was little evidence of an association between severe events and distress. Ethnicity had little effect on any associations although South Asian women were at slightly higher odds of experiencing emotional symptoms, which appear to be buffered by social support.In routine antenatal care it is important to assess both emotional and somatic symptoms. Health professionals need to be sensitive to the health, social, cultural and environmental circumstances of women during pregnancy and ensure appropriate support is in place, particularly for multi-parous women. Regression models explained a small but significant amount of the variance in distress symptoms. Further work is necessary to explore other contributory factors and also the mechanisms through which stressors have their effect.

Objectives. This study aimed to explore how guidance contributes to the outcome of self-help for disordered eating. Method. A sample of guides and clients with a range of disordered eating was interviewed on completion of a randomized control trial and analysed using thematic framework analysis. Results. Four themes emerged; the necessity of having a guide as a facilitator, features of the therapeutic relationship in clients with positive outcomes, features of the therapeutic relationship in clients with poor outcomes, and client suitability. Conclusions. These findings have implications for the delivery of guided self-help interventions for disordered eating. They suggest the value of assessing clients’ readiness to change, working with clients with less severe and complex conditions, and the importance of guide qualities and skills.

Current treatment of depression is a waste of money Depression is a chronic illness with a highly recurrent course, since relapse rates rise up to 90%after multiple previous episodes. In the Netherlands the costs originating from depression are high. The current treatment costs accumulate up to 660 million euro’s, and the costs related to loss of productivity rise to 950 million euro’s each year. The guidelines of the American Psychiatric Association advices therapists to continue treatment until a patient is completely symptom free, since residual symptoms are a known predictor of relapse. However, due to changes in financing the mental healthcare system therapists are stimulated to end treatment soon. By neglecting the risk of relapse, the current treatment of depression is a waste of money. Currently, the most used strategy to prevent relapse in depression is continuation of antidepressants after remission. However,most patients are not able or willing to continue antidepressants lifelong. Cognitive therapy has prophylactic effects beyond the acute phase of depression. Specific preventive cognitive therapy offered after remission, either in group format or via the internet could prove to be a cost-effective alternative for antidepressants in preventing relapse, since it has shown to prevent relapse in previous studies.

Treatment guidelines recommend evidence-based guided self-help (GSH) as the first stage of treatment for bulimia nervosa and binge eating disorder. The current randomised control trial evaluated a cognitive behavioural therapy-based GSH pack, 'Working to Overcome Eating Difficulties,' delivered by trained mental health professionals in 6 sessions over 3 months. It was congruent with the transdiagnostic approach and so was intended as suitable for all disordered eating, except severe anorexia nervosa. Eighty one clients were randomly allocated to either a GSH or waiting list condition. Eating disorder psychopathology (EDE-Q), key behavioural features and global distress (CORE) were measured at pre- and post-intervention, and 3- and 6-month follow-up. Results showed significant improvements in eating disorder psychopathology, laxative abuse, exercise behaviours, and global distress, with the GSH condition being superior to the waiting list on all outcomes. Treatment gains were maintained at 3 and 6 months. This study adds to the evidence supporting GSH for disordered eating, including EDNOS. However, further work is needed to establish the factors that contribute to observed therapeutic improvements and determine for whom GSH is most suitable.

Three related courses examining the connection between chemistry and art have been developed for study-abroad programs in Florence, Italy, by faculty members at Gonzaga University and Mount Saint Mary’s University. These courses are described with the intent of providing a general framework for the development of chemistry and art courses in other locations. Course descriptions, syllabi, relevant resources, and methods of evaluation for all three courses have been included in the online supporting information.

Lesbian and bisexual women from diverse backgrounds possess unique viewpoints regarding the meanings and functions of “community.” Despite this, few studies have explored sexual minority women's understanding of and relationship to their communities. The present study employed qualitative research methods to investigate the meanings and functions of community among a sample of ethnically diverse lesbian and bisexual women (N=49). From the participants' responses in semistructured focus groups and key informant interviews, three core constructs emerged: community concepts (relevance, meaning), community-based strain (racism, homophobia, biphobia, classism), and community-based action (fluidity, exclusivity). Implications of these findings for future research and practice with this population of women will be discussed. © 2009 Wiley Periodicals, Inc.

The authors investigated ethnicity, self-construal, and distress among African American and Asian American college students. African American students expressed more salient independent self-construals, whereas Asian American students expressed more salient interdependent self-construals. As hypothesized, among African American participants, distress was positively related to interdependent self-construal and negatively associated with independent self-construal. Contrary to prediction, the same pattern was found for Asian American participants. Multicultural clinical practice implications are presented. ********** The combination of academic, social, financial, and other adjustment demands that typically are associated with the college transition, occurring at a time when individuals often are developmentally predisposed to the onset of various psychological disorders, can increase a student's vulnerability to distress (Voelker, 2004). For example, national surveys have indicated that symptoms of depression are most prevalent among people who are 18 to 29 years old (Schieman, Van Gundy, & Taylor, 2001) and that nearly 75% of individuals with diagnosable anxiety disorders experienced their first symptoms before they were 21 years old (Kessler et al., 2005). Similarly, Furr, Westefeld, McConnell, and Jenkins (2001) reported that 53% of students had experienced some form of depression when in college, 9% had contemplated committing suicide, and 1% had engaged in at least one suicide attempt. In the American College Health Association's (2007) National College Health Assessment, 93% of students reported feeling overwhelmed during the previous year and 44% reported that they "felt so depressed it was difficult to function" (p. 205). Ethnicity and College Student Distress Researchers have suggested that ethnic minority students, in comparison with their ethnic majority peers, may be even more likely to experience distress and express apprehension about the rigors of college (Jones, Castellanos, & Cole, 2002). Moreover, generally speaking, ethnic minority students tend to encounter unique challenges not experienced by majority students (Marcus et al., 2003). Ethnic minority students may experience heightened distress as a result of experiences with racial discrimination, difficulty adapting to a predominantly White college culture, and community disengagement (Gloria, Hird, & Navarro, 2001). Although extant research has indicated that these types of additional stressors affect various ethnic groups on campus (U.S. Department of Health and Human Services, 2001), we focused only on African American and Asian American college students in the present study. African American students seem more likely than do their White American peers to report unfair treatment on college and university campuses (Fries-Britt & Turner, 2001; Walden, 1994). African American students also have reported experiencing greater social isolation and more difficulties with interpersonal interactions with faculty and peers (Sedlacek, 1987; Swim, Hyers, Cohen, Fitzgerald, & Bylsma, 2003). Furthermore, according to Landrine and Klonoff (1996), 98% of African Americans experienced racial discrimination during the past year, and 100% reported experiencing racial discrimination at some point during their lifetime. In turn, experiences of discrimination and racism are key factors leading to distress and other mental health concerns among racial and ethnic minority students, and among African American learners in particular (R. Clark, Anderson, Clark, & Williams, 1999). Asian American students also tend to report more experiences of depression and social anxiety than do their majority student peers (Okazaki, 1997, 2000; Okazaki & Kallivayalil, 2002; Sue, Ino, & Sue, 1983). Lee, Lei, and Sue (2001) suggested that Asian American students tend to experience considerable stress and anxiety as a result of perceived parental pressures to achieve academically. …

Planar supported lipid bilayers that are stable under ambient atmospheric and ultra-high-vacuum conditions were prepared by cross-linking polymerization of bis-sorbylphosphatidylcholine (bis-SorbPC). X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were employed to investigate bilayers that were cross-linked using either redox-initiated radical polymerization or ultraviolet photopolymerization. The redox method yields a more structurally intact bilayer; however, the UV method is more compatible with incorporation of transmembrane proteins. UV polymerization was therefore used to prepare cross-linked bilayers with incorporated bovine rhodopsin, a light-activated, G-protein-coupled receptor (GPCR). A previous study (Subramaniam, V.; Alves, I. D.; Salgado, G. F. J.; Lau, P. W.; Wysocki, R. J.; Salamon, Z.; Tollin, G.; Hruby, V. J.; Brown, M. F.; Saavedra, S. S. J. Am. Chem. Soc. 2005, 127, 5320–5321) showed that rhodopsin retains photoactivity after incorporation into UV-polymerized bis-SorbPC, but did not address how the protein is associated with the bilayer. In this study, we show that rhodopsin is retained in supported bilayers of poly(bis-SorbPC) under ultra-high-vacuum conditions, on the basis of the increase in the XPS nitrogen concentration and the presence of characteristic amino acid peaks in the ToF-SIMS data. Angle-resolved XPS data show that the protein is inserted into the bilayer, rather than adsorbed on the bilayer surface. This is the first study to demonstrate the use of ultra-high-vacuum techniques for structural studies of supported proteolipid bilayers.

Three-dimensional haptic matrices were pilot-tested as a nonvisual measure of cognitive ability. The results indicated that they correlated with convergent measures, with emphasis on spatial processing and that the participants who described items "visually" completed them more quickly and accurately and tended to have become visually impaired more recently than the other participants. ********** Norm-referenced tests of cognitive abilities often provide information that is useful in developing curricula, behavioral management strategies, and the like for students with special needs, including those with visual impairments (that is, those who are blind or have low vision). Although direct observation of the behavior of students and the evaluation of specific academic skills through testing provides crucial contextual clues to current function or dysfunction, cognitive-neuropsychological testing may provide estimates of broad, less contextual, abilities that underlie a variety of observable behaviors. Testing may both confirm direct observations and explain why behaviors do or do not manifest, often allowing teachers, psychologists, and other professionals to address the "root" of an academic or adjustment problem. Most standardized measures of nonverbal ability are administered and interpreted visually. That is, vision is required for participants to interact with the test materials during the administration of such measures (Wechsler, 1997), and when the results are interpreted, functional vision is assumed; measures of "sensory-motor integration" are, more specifically, measures of the integration of movement and vision (McGrew & Flanagan, 1998). Although tests have been developed to assess various nonverbal cognitive abilities of persons who are visually impaired (Newland, 1971; Reid, 2002), many of them are not made available to assessment professionals (Taylor & Ward, 1990), were never renormed to remain current (see, for example, Shurrager, 1961), or are not as widely used with persons who are visually impaired as are more familiar instruments that were developed for use with sighted people, such as the Wechsler scales (see Bauman & Kropf, 1979; J. Miller & Skillman, 2003). Background TESTS OF NONVERBAL ABILITIES The disuse of specialized instruments is distressing, given the wealth of evidence suggesting that the application of standard verbal tests to persons who are visually impaired is inappropriate. Although the administration of standard verbal tests is not intuitively contraindicated, research has shown an item bias in the Wechsler verbal subscales (Tillman, 1967). Other research has found differences in specific abilities as a function of visual status and history--for example, a greater auditory memory span among people who are blind than among those who are sighted (Vander Kolk, 1977a, 1977b) and among children who are congenitally blind versus those who are adventitiously blind (Hull & Mason, 1995). Because blindness reduces the opportunity for incidental learning, it may skew the performance on verbal tests, which often sample heavily from "crystallized knowledge" (such as vocabulary, the mastery of facts or trivia, and knowledge of social norms). It is likely that test takers with visual impairments display a unique array of verbal-cognitive competencies that are distinct from those of the sighted norming sample (L. R. Miller, 1977). Nonverbal portions of popular test batteries are more obviously suspect. Although most standardized nonverbal tests are inarguably inaccessible to persons without useful vision, severe decrements in performance have also been observed with even modest reductions in visual acuity (Groenveld & Jan, 1992). The absence of nonverbal tests (the use of only verbal tests) reduces the breadth and interpretability of assessment data, lowering the reliability of composite scores (like factor scores and intelligence quotient) or precluding their estimation. …

Background There is a paucity of research on the nature of life adversity in depressed and non-depressed older adults. Early life events work used in-depth interviews; however, larger epidemiological trials investigate life adversity using brief questionnaires. This study investigates the type of life adversity experienced in later life and its association with depression and compares adversity captured using a brief (LTE-Q) and in-depth (LEDS) measure. Methods 960 participants over 65 years were recruited in UK primary care to complete the PHQ-9 and LTE-Q. A sub-sample (n=19) completed the LEDS and a question exploring the subjective experience of the LTE-Q and LEDS. Results Important life adversity was reported on the LTE-Q in 48% of the sample. In the LTE-Q sample the prevalence of depression (PHQ-9≥10) was 12%. Exposure to recent adversity was associated with doubling of the odds of depression. The LTE-Q only captured a proportion of adversity measured by the LEDS (42% vs 84%). Both measures showed health, bereavement and relationship events were most common. Limitations The cross-sectional design limits the extent to which inferences can be drawn around the direction of causality between adversity and depression. Recall in older adults is questionable. Conclusions UK older adults face adversity in areas of health, bereavement and relationships which are associated with depression. This has clinical relevance for psychological interventions for older adults to consider social context and social support. It helps identify the strengths and weaknesses of a brief adversity measure in large scale research. Further research is needed to explore the mechanisms of onset and direction of causality.

SummaryFree-living individuals have multifaceted diets and consume foods in numerous combinations. In epidemiological studies it is desirable to characterize individual diets not only in terms of the quantity of individual dietary components but also in terms of dietary patterns. We describe the conditional Gaussian mixture model for dietary pattern analysis and show how it can be adapted to take account of important characteristics of self-reported dietary data. We illustrate this approach with an analysis of the 2000–2001 National Diet and Nutrition Survey of adults. The results strongly favoured a mixture model solution allowing clusters to vary in shape and size, over the standard approach that has been used previously to find dietary patterns.

Based on previous research on self-construals, the theory of reasoned action, and persuasive communication, we hypothesized that individual, behavioral-focused information would be more effective in increasing help-seeking intention among college students in the United States, whereas relational, normative-focused information would be more effective among college students in Thailand. Results partially supported these predictions suggesting that differing information can enhance help-seeking intention across cultures.

Direct-care paraprofessionals' recognition of psychopathology of varying severity in persons with mental retardation was evaluated. Factors that may influence paraprofessionals' decisions to initiate referrals for mental health services on behalf of individuals with mental retardation were also evaluated. Results suggest that staff members recognized and differentiated psychopathology of varying levels of clinical severity. Results also suggest that paraprofessionals are more likely to initiate making a referral when professionals are perceived as being competent in treating individuals with mental retardation, and when providers' interventions are consistent with the referring agency's philosophy.

Importance: There is little evidence to guide management of depressive symptoms in older people. Objective: To evaluate whether a collaborative care intervention can reduce depressive symptoms and prevent more severe depression in older people. Design, Setting, and Participants: Randomized clinical trial conducted from May 24, 2011, to November 14, 2014, in 32 primary care centers in the United Kingdom among 705 participants aged 65 years or older with Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) subthreshold depression; participants were followed up for 12 months. Interventions: Collaborative care (n=344) was coordinated by a case manager who assessed functional impairments relating to mood symptoms. Participants were offered behavioral activation and completed an average of 6 weekly sessions. The control group received usual primary care (n=361). Main Outcomes and Measures: The primary outcome was self-reported depression severity at 4-month follow-up on the 9-item Patient Health Questionnaire (PHQ-9; score range, 0-27). Included among 10 prespecified secondary outcomes were the PHQ-9 score at 12-month follow-up and the proportion meeting criteria for depressive disorder (PHQ-9 score ≥10) at 4- and 12-month follow-up. Results: The 705 participants were 58% female with a mean age of 77 (SD, 7.1) years. Four-month retention was 83%, with higher loss to follow-up in collaborative care (82/344 [24%]) vs usual care (37/361 [10%]). Collaborative care resulted in lower PHQ-9 scores vs usual care at 4-month follow-up (mean score with collaborative care, 5.36 vs with usual care, 6.67; mean difference, −1.31; 95% CI, −1.95 to −0.67; P

Elgersma HJ, Bockting CLH, Kok GD. Terugvalpreventie bij depressie. Huisarts Wet 2011;54(2):65–7. Over twintig jaar zal depressie vermoedelijk gestegen zijn naar een tweede plaats op de ranglijst van ziektebeelden die het meeste lijden en kosten met zich meebrengen. Dat komt vooral doordat het een chronische aandoening is terwijl de behandeling zich vooralsnog sterk richt op de acute fase, op ‘cure’ dus. Om een volgende depressieve episode te voorkomen, zijn de meeste patienten nog steeds aangewezen op een ‘onderhoudsbehandeling’ met antidepressiva, hoewel aangetoond is dat psychologische interventies soms meer bescherming bieden. Vanwege de toenemende persoonlijke en maatschappelijke kosten verdient de preventie van recidiverende depressies extra aandacht. Om de vereiste continuiteit van zorg te realiseren, moeten de eerste en de tweede lijn (de GGZ) meer en beter samenwerken. In dit artikel houden wij twee soorten psychologische interventies tegen het licht die ook in de eerste lijn prima toepasbaar zijn: preventieve cognitieve therapie (PCT) en interventies via internet, e-mental-health.

Background: Depression accounts for the greatest disease burden of all mental health disorders, contributes heavily to healthcare costs, and by 2020 is set to become the second largest cause of global disability. Although 10% to 16% of people aged 65 years and over are likely to experience depressive symptoms, the condition is under-diagnosed and often inadequately treated in primary care. Later-life depression is associated with chronic illness and disability, cognitive impairment and social isolation. With a progressively ageing population it becomes increasingly important to refine strategies to identity and manage depression in older people. Currently, management may be limited to the prescription of antidepressants where there may be poor concordance; older people may lack awareness of psychosocial interventions and general practitioners may neglect to offer this treatment option. Methods/design: CASPER Plus is a multi-centre, randomised controlled trial of a collaborative care intervention for individuals aged 65 years and over experiencing moderate to severe depression. Selected practices in the North of England identify potentially eligible patients and invite them to participate in the study. A diagnostic interview is carried out and participants with major depressive disorder are randomised to either collaborative care or usual care. The recruitment target is 450 participants. The intervention, behavioural activation and medication management in a collaborative care framework, has been adapted to meet the complex needs of older people. It is delivered over eight to 10 weekly sessions by a case manager liaising with general practitioners. The trial aims to evaluate the clinical and cost effectiveness of collaborative care in addition to usual GP care versus usual GP care alone. The primary clinical outcome, depression severity, will be measured with the Patient Health Questionnaire-9 (PHQ-9) at baseline, 4, 12 and 18 months. Cost effectiveness analysis will assess health-related quality of life using the SF-12 and EQ-5D and will examine cost-consequences of collaborative care. A qualitative process evaluation will be undertaken to explore acceptability, gauge the extent to which the intervention is implemented and to explore sustainability beyond the clinical trial. Discussion: Results will add to existing evidence and a positive outcome may lead to the commissioning of this model of service in primary care. Trial registration: ISRCTN45842879 (24 July 2012).

One hundred and twenty families and their 4-year-old children participated in a study on family stories. The participants were primarily White (91%), with the remainder Black (4%), Hispanic (2%), and Asian (2%). The parents were primarily middle class and upper class, with approximately 5% identifying themselves as from a lower socioeconomic background. Parents were asked to tell their son or daughter stories about when the parent was growing up. All parents completed measures of child behavior and a subset of parents completed the Bem Sex Role inventory. Stories were coded for the strength of affiliation, achievement, and autonomy themes. No gender differences were found for parents or child in the strength of affiliation themes. Fathers told stories with stronger autonomy themes than did mothers, and sons were more likely to hear stories with themes of autonomy than were daughters. An interaction was found between gender type of parent and gender of child for strength of achievement theme. Traditional gender-typed parents told stories with stronger achievement themes to their sons, and nontraditional gender-typed parents told stories with stronger achievement themes to their daughters. Exploratory analyses were conducted examining the relations among story theme, parent gender type, and child behavior. Higher levels of externalizing behaviors were found in boys whose fathers endorsed strong masculine attitudes, but told stories with weak achievement themes. Higher levels of internalizing behaviors were found in girls whose mothers told stories with strong affiliation themes, but endorsed weak feminine attitudes. Family stories are proposed to be one aspect of socialization that includes an interaction between child and parent characteristics.

Cytomegalovirus (CMV) infection increases the risk of complications after renal transplantation, but the mechanisms controlling donor-derived infection are not adequately characterized. Here, we assessed the risk of clinically significant CMV disease in donor-seropositive, recipient-seropositive (D+R+) renal transplantation and examined recipients’ CMV antigen-specific cellular immune responses primed directly by donor cells. In a retrospective cohort of 569 patients administered standardized basiliximab-tacrolimus-mycophenolate-corticosteroid immunosuppressive therapy, CMV disease rates increased in D+R+ serostatus pairings compared with D−R+ pairings (hazard ratio [HR], 2.61; 95% confidence interval [CI], 1.36 to 5.01; P=0.004) and associated with increased donor-recipient HLA mismatch in the D+R+ group (HR [per class 1 mismatch], 1.43; 95% CI, 1.12 to 1.82]; P=0.02). D+R+ and D+R− transplants in which the donor and recipient differentially expressed at least one HLA class I allele were followed prospectively from the time of transplantation. During the first year after transplantation, four of eight seropositive recipients and one of three seronegative recipients displayed peripheral blood CD8+ T cell responses to CMV presented by recipient-specific HLA. Notably, no recipients mounted responses to CMV presented by donor-specific HLA, despite the detection of CMV antigen expression in all seropositive donor organs examined (n=10), suggesting that the allograft of Class I HLA-mismatched seropositive donors is inaccessible to CD8+ T cell responses. Finally, pretransplant assays of anti-CMV cellular immunity predicted post-transplant CMV replication less accurately in D+R+ pairings than in D−R+ pairings, possibly reflecting in vitro assay specificity for recipient, rather than donor, HLA. These findings are relevant to the clinical management and immunologic understanding of donor-transmitted viral infection.

Th e exquisite beauty of plants and their fundamental importance to life on Earth has captivated scientists throughout history. During antiquity, Th eophrastus began the systematic characterization of plants according to Aristotle’s principles of taxonomy. Centuries later, Mendel’s studies of the inheritance of traits in pea plants founded the fiof genetics, and much of Darwin’s work on the evolution of forms by natural selection was supported by experiments on plants. By 2000, the seeds of success were sown in the fiof plant genomics with the sequencing of the genome of Arabidopsis thaliana [1], a ubiquitous weed that was adopted as the plant model species in the 1990s due to its many desirable traits, such as a short generation time, small diploid genome, and self­compatibility. Prior to this adoption of Arabidopsis as a model species, studying a panoply of agronomically and economically important species, such as maize, rice, tomato, petunia and snapdragon, had been favored. Th e burgeoning worldwide human population means the pressure to produce sustainable quantities of food and fuel crops, across a relatively constant land area, has never been higher. To improve yields of crops, it will be imperative to understand the genetic mechanisms con­ trolling traits of interest, and genomics approaches will be vital to achieve this. Th us, with the topic of plant genomics at an unprecedented level of importance, we feel it is pertinent to highlight the best of plant research in a special issue.

Background: Alcohol consumption in the student population continues to be cause for concern. Building on the established evidence base for traditional brief interventions, interventions using the Internet as a mode of delivery are being developed. Published evidence of replication of initial findings and ongoing development and modification of Web-based personalized feedback interventions for student alcohol use is relatively rare. The current paper reports on the replication of the initial Unitcheck feasibility trial. Objective: To evaluate the effectiveness of Unitcheck, a Web-based intervention that provides instant personalized feedback on alcohol consumption. It was hypothesized that use of Unitcheck would be associated with a reduction in alcohol consumption. Methods: A randomized control trial with two arms (control=assessment only; intervention=fully automated personalized feedback delivered using a Web-based intervention). The intervention was available week 1 through to week 15. Students at a UK university who were completing a university-wide annual student union electronic survey were invited to participate in the current study. Participants (n=1618) were stratified by sex, age group, year of study, self-reported alcohol consumption, then randomly assigned to one of the two arms, and invited to participate in the current trial. Participants were not blind to allocation. In total, n=1478 (n=723 intervention, n=755 control) participants accepted the invitation. Of these, 70% were female, the age ranged from 17-50 years old, and 88% were white/white British. Data were collected electronically via two websites: one for each treatment arm. Participants completed assessments at weeks 1, 16, and 34. Assessment included CAGE, a 7-day retrospective drinking diary, and drinks consumed per drinking occasion. Results: The regression model predicted a monitoring effect, with participants who completed assessments reducing alcohol consumption over the final week. Further reductions were predicted for those allocated to receive the intervention, and additional reductions were predicted as the number of visits to the intervention website increased. Conclusions: Unitcheck can reduce the amount of alcohol consumed, and the reduction can be sustained in the medium term (ie, 19 weeks after intervention was withdrawn). The findings suggest self-monitoring is an active ingredient to Web-based personalized feedback. © Bridgette M Bewick, Robert M West, Michael Barkham, Brendan Mulhern, Robert Marlow, Gemma Traviss, Andrew J Hill.
