Abstract
Neuroimaging markers based on Magnetic Resonance Imaging (MRI) combined with various other measures (such as genetic covariates, biomarkers, vascular risk factors, neuropsychological tests etc.) might provide useful predictions of clinical outcomes during the progression towards Alzheimer's disease (AD). The use of multiple features in predictive frameworks for clinical outcomes has become increasingly prevalent in AD research. However, many studies do not focus on systematically and accurately evaluating combinations of multiple input features. Hence, the aim of the present work is to explore and assess optimal combinations of various features for MR-based prediction of (1) cognitive status and (2) biomarker positivity with a multi-kernel learning Gaussian process framework. The explored features and parameters included (A) combinations of brain tissues, modulation, smoothing, and image resolution; (B) incorporating demographics & clinical covariates; (C) the impact of the size of the training data set; (D) the influence of dimensionality reduction and the choice of kernel types. The approach was tested in a large German cohort including 959 subjects from the multicentric longitudinal study of cognitive impairment and dementia (DELCODE). Our evaluation suggests the best prediction of memory performance was obtained for a combination of neuroimaging markers, demographics, genetic information (ApoE4) and CSF biomarkers explaining 57% of outcome variance in out-of-sample predictions. The highest performance for Aβ42/40 status classification was achieved for a combination of demographics, ApoE4, and a memory score while usage of structural MRI further improved the classification of individual patient's pTau status.

Abstract
Abstract
Aim
Bowel incarceration is common complication in incarcerated hernias, which involves one of the most frequent emergent surgical pathologies.
Real-time fluorescence angiography with ICG is a reliable technique that allows surgeons to assess intestinal blood flow. However, this technique is rarely used in emergency surgery such as incarcerated hernia repair.
Materials & methods
We present the case of a 64-year-old patient with medical history of high blood pressure, atrial fibrillation and hepatitis C, complaining of abdominal pain and vomiting associated to painful inguinal hernia in the past 12 hours. The patient presented inguinal incarcerated hernia without any signs of external complication or elevation of infection and inflammatory parameters in blood test.
Results
We decided to carry out an urgent hernia repair performing transabdominal preperitoneal (TAPP) approach.
Once the hernia was repaired, intraoperative ICG fluorescence angiography was performed in order to evaluate intestinal viability. ICG fluorescence revealed the presence of irreversible ileal ischemia (12 cm) needing resection. Through mini-Pfannenstiel incision we performed the resection and a side to side stapled anastomosis. Postoperative course was uneventful and the patient was discharged 3 days after the surgery.
Conclusions
The combination of laparoscopic approach and ICG fluorescence angiography seems to be an actual useful solution, combining the advantages of minimally invasive surgery and avoiding the risk of bowel perforation due to unnoticed ischemia thanks to the assess of intestinal perfusion.

Abstract
Abstract
Aim
The use of tackers for peritoneal closure in TAPP (transabdominal preperitoneal approach) is controversial because of the associated risk of vasculo-nerve injury. We present the case of a 56 years old male who came for hypovolemic shock due to hemoperitoneum after TAPP hernia repair in another center 72 hours earlier.
Material & Methods
We opted for an exploratory laparoscopy showing a massive hemoperitoneum due to a bleeding from the left epigastric artery at the site of placement of a tacker. Hemostasis was performed with bipolar energy and peritoneal approximation with glue after washing and aspiration.
Results
The patient was discharged on the third day without any complications.
Conclusions
Peritoneal flap closure in TAPP remains a controversial issue despite finding no significant differences between the different closure methods in the literature. Blind placement may injure vessels and nerves that require subsequent urgent surgery.
In selected patients, if the patient is stable, laparoscopy through the same trocars is a safe and reliable option to resolve hemoperitoneum after epigastric artery injury.

Abstract
The objective of this study is to describe the frequency and the clinical, paraclinical, and treatment profile of patients with lupus psychosis in a Colombian cohort of patients with systemic lupus erythematosus (SLE). This retrospective cohort study evaluated epidemiological and clinical characteristics, results of neuroimaging, analysis of the cerebrospinal fluid, treatment, and disease evolution in patients with lupus psychosis. Among 2,479 patients with SLE, six female patients aged between 20 and 50 years with a diagnosis of lupus psychosis were identified. In two patients, psychosis was present at disease onset and in the other four, SLE was already present, although the majority of them were diagnosed less than two years prior to the onset of psychosis. The entire cohort had high disease activity as measured by SLEDAI-2K. We found concomitant cutaneous, joint, and hematological alterations. Cerebrospinal fluid data were obtained in half of the patients and were normal. We performed brain tomography on most of our patients, which was almost always described as normal. In 5 out of 6 patients, the induction therapy to treat psychosis was based on steroids, and in the majority of them, a resolution of psychiatric symptoms was observed after initiating treatment. Lupus psychosis is a rare event that usually occurs early in the course of the disease and is associated with other manifestations of SLE. This investigation mainly found concomitant cutaneous, joint, and hematological manifestations, with a favorable outcome after treatment, as described in the literature.

Abstract
BACKGROUND Frailty is a complex geriatric syndrome arising from a combination of genetic and environmental factors and is associated with adverse health outcomes and mortality. A recent study reported an association between variants of the 9p21-23 locus, associated with a number of age-related disorders, including Alzheimer's disease (AD), and frailty. Frailty has been associated with increased risk of developing AD and it has been proposed that frailty burden may modify AD clinical presentation. In view of the overlapping genetic architecture between the two disorders, it is noteworthy to conduct studies to uncover risk variants that contribute to both AD and frailty. The purpose of this study is to test the reproducibility of the association of 9p21-23 locus with frailty in a population that is ethnically different from previous work and in the context of multidimensional definitions of frailty that will allow us to examine the potential impact to domains pertaining to AD pathology. METHODS We operationalized frailty according two definitions and the corresponding instruments, the Frailty Index (FI) and the Tilburg Frailty Indicator (TFI) and we determined genotypes of eight alleles previously identified as risk increasing for frailty in 1172 community-dwelling older participants (57% females) from the HELIAD study with a mean age of 74 years old. We cross-sectionally investigated the association between risk alleles and frailty, as well as with specific components of each definition using linear regression analyses adjusted for age, sex and years of education. RESULTS Compared to non-carriers, carriers of rs7038172 C risk allele, were associated with a higher FI Score (β=0.089, p=0.002). Similarly, we found a positive association between the presence of at least one rs7038172 C variant and TFI score (β=0.053, p=0.04). Moreover, the rs7038172 variant was associated, irrespectively of dementia status, with the memory and psychological domain of FI and TFI, respectively. CONCLUSION Our study confirms the association of the rs7038172 C allele with the frailty syndrome in a Greek population and in the context of multidimensional definitions of frailty. Furthermore, we report novel associations between this allele and the memory domain of FI and the psychological domain of TFI, that includes memory problems on its components. Given that frailty burden has been shown to modify the AD clinical presentation, it is likely that rs7038172 C allele may accelerate the transition of AD or frailty to dementia Overall, our study corroborates the role of the 9p21-23 region in frailty development and draw potential links with AD pathology.

Abstract
Recently, there has been an increase in the use of compounded topical pain preparations, raising concerns that clinicians and patients may not be aware of the potential safety risks. Topical diclofenac is one of the most widely used pain medications, often used for joint ailments such as osteoarthritis and other musculoskeletal pain. Systemic exposure to diclofenac has a dose-related risk for gastrointestinal, cardiovascular, and renal adverse events, particularly in elderly patients. Topical diclofenac preparations are frequently compounded in pharmacies at the concentrations of 1% to 10% (or higher) with or without other active ingredients such as camphor. Considering the significantly higher strengths of the compounded preparations as compared to the commercially available products (1% to 3%) and the frequency of application (sometimes up to six times a day), concerns arise as to the levels of absorption with these formulations and their potential toxicity. The objective of this initial study was formulated in an attempt to shed light on safety concerns of topical diclofenac preparations. A study was designed to evaluate the in vitro release, irritability, and permeability of three different concentrations of compounded diclofenac gels (1%, 5%, and 10%) in PLO GEL MEDIFLO and VersaPro Gel bases. Using MatTek's EpiDerm system, skin irritability and the in vitro permeation of compounded diclofenac gels were evaluated. Additionally, the in vitro release profile, drug content, content uniformity, and physical properties of the compounded gels (pH, homogeneity) were assessed. In all cases, the drug content, content uniformity, physical properties, and preparation stability during the recommended beyond-use dating (90 days) were acceptable. The release profiles of all tested preparations followed the Higuchi model. The in vitro skin irritation evaluation of the tested formulations indicated no irritant preparation. The permeability assessment of the formulated gels revealed that there is a correlation between drug release and percutaneous absorption. VersaPro Gelbased preparations, which showed a lower percentage of drug release over the experiment time, showed a significantly lower average flux at steady-state and the average percentage of absorbed dose after 24 hours. The percentage absorption (%abs) from different formulations ranged from 11.18% to 19.6% depending on the gel base. The permeability coefficient, kp, (cm/hr) ranged from 0.019 to 0.037, and the average flux (µg/cm2/hr) ranged from 8.7 to 103 depending on the gel base and the diclofenac concentration. Based on our findings and previously reported data, the possibility exists that higher diclofenac concentrations in compounded topical preparations may lead to significantly higher blood concentrations as compared to commercially available products, which in turn may also lead to serious side effects. Accordingly, there is a need for clinical studies to evaluate the safety of compounded diclofenac preparations with higher diclofenac contents than United States Food and Drug Administrationapproved formulations.

Abstract
BACKGROUND In breeding herds, porcine reproductive and respiratory syndrome (PRRS) clinically manifests as increased abortions, number of stillbirths, and pre-weaning mortality, and as a direct consequence, results in a decrease of the number of piglets weaned per sow per year. Breeding farm classification according the PRRS virus (PRRSV) status (unstable or stable) is a key control strategy for this disease. The aim of this study was to evaluate the production improvement related to achieving a PRRSV stable status in breeding herds in Spain. For this purpose, epidemiological and productivity data were collected from a systematic PRRSV monitoring program in 35 breeding herds from a large integrated swine group in Spain. A comparative statistical analysis was conducted using four key production indicators (KPI) between different PRRSV status and a generalized linear mixed model: weekly abortions/1000 sows (ABTHS), born-alive rate (BAR), pre-weaning mortality rate (PWMR), and number of weaned piglets per 1000 sows (WPTHS). RESULTS From the 35 monitored farms during a total period of 58 weeks, we collected 49 to 58 weeks of production data and PRRSV classification status for each study farm. This represented a total of 1997 (741 unstable and 1256 stable) weekly data collected that was eligible for the KPI comparative study. PRRSV stability was associated with significant improvement in BAR (+ 1.10 %, p < 0.001), PWMR (-0.88 %, p < 0.002) and WPTHS (+ 24.52, p < 0.0001). CONCLUSIONS These results demonstrate for the first time the improved production due to achieving PRRSV stability in breeding herds under field conditions in a European country. Increased number of born-alive piglets and a reduction of piglet pre-weaning mortality represents an increase of 1.28 weaned piglets per sow per year if PRRSV stability was achieved and maintained for one-year period in a breeding farm.

Abstract
OBJECTIVE Obsessive-compulsive disorder (OCD) is a complex psychiatric disorder with a substantial genetic contribution. While the specific variants underlying OCD's heritability are still unknown, findings from genome-wide association studies (GWAS) corroborate the importance of common SNPs explaining the phenotypic variance in OCD. Investigating associations between the genetic liability for OCD, as reflected by a polygenic risk score (PRS), and potential endophenotypes of the disorder, such as the personality trait harm avoidance, may aid the understanding of functional pathways from genes to diagnostic phenotypes. METHODS We derived PRS for OCD at several P-value thresholds based on the latest Psychiatric Genomics Consortium OCD GWAS (2688 cases, 7037 controls) in an independent sample of OCD patients (n = 180), their unaffected first-degree relatives (n = 108) and healthy controls (n = 200). Using linear regression, we tested whether these PRS are associated with the personality trait harm avoidance. RESULTS Results showed that OCD PRS significantly predicted OCD status, with patients having the highest scores and relatives having intermediate scores. Furthermore, the genetic risk for OCD was associated with harm avoidance across the entire sample, and among OCD patients. As indicated by mediation analyses, harm avoidance mediated the association between the OCD PRS and OCD caseness. These results were observed at multiple P-value thresholds and persisted after the exclusion of patients with a current comorbid major depressive or anxiety disorder. CONCLUSION Our findings support the polygenic nature of OCD and further validate harm avoidance as a candidate endophenotype and diathesis of OCD.

Abstract
Purpose To investigate cross-sectional associations between dietary patterns and cognitive functioning in elderly free of dementia. Methods Data of 389 participants from the German DELCODE study (52% female, 69 ± 6 years, mean Mini Mental State Score 29 ± 1) were included. The sample was enriched with elderly at increased risk for Alzheimer’s disease (AD) by including participants with subjective cognitive decline, mild cognitive impairment (MCI) and siblings of AD patients. Mediterranean and MIND diets were derived from 148 Food Frequency Questionnaire items, and data-driven patterns by principal component analysis (PCA) of 39 food groups. Associations between dietary patterns and five cognitive domain scores were analyzed with linear regression analyses adjusted for demographics (model 1), and additionally for energy intake, BMI, other lifestyle variables and APOe4-status (model 2). For PCA-derived dietary components, final model 3 included all other dietary components. Results In fully adjusted models, adherence to Mediterranean and MIND diet was associated with better memory. The ‘alcoholic beverages’ PCA component was positively associated with most cognitive domains. Exclusion of MCI subjects (n = 60) revealed that Mediterranean and MIND diet were also related to language functions; associations with the alcoholic beverages component were attenuated, but most remained significant. Conclusion In line with data from elderly population samples, Mediterranean and MIND diet and some data-derived dietary patterns were related to memory and language function. Longitudinal data are needed to draw conclusions on the putative effect of nutrition on the rate of cognitive decline, and on the potential of dietary interventions in groups at increased risk for AD.

Abstract
Modern society benefits from the improvement of life quality and life expectancy compared to society 50 or 100 years ago (1). However, living longer is also accompanied by negative developments which include an increase in the incidence of non-communicable chronical diseases (NCDs), such as diabetes, cardiovascular diseases, neurodegenerative disorders, cancer. In fact, NCDs are becoming one of the greatest threats of our time (2). Why is that? because NCDs have a deep impact at key levels of our society, including the individuum level and the economic level, though often both levels are interconnected and influenced by each other. At the personal level, NCDs have a profound effect on the quality of life of the affected person, as well as on the person’s family and on caregivers. As an example, we can consider a person who is diagnosed with dementia. For this patient begins an irreversible and unstoppable journey in the complete dependency from others and, after a given time of progression, to death, even if the patient is treated with the best disease-modifying therapies. For the patient self, this diagnose means early retirement from working life reducing consequently familial income. Given the limitation of dementia patients in their daily life activities, one or more family members will need to reduce time at work or completely take time off to care for the patient. However, increasing dependency developed by the patient will lead, sooner or later, to deep changes in the familial routine to take care of the patient that will also be associated with threatening financial problems for the complete family. Moreover, the emotional and physical drain produced while dementia progresses can be overwhelming for family and caregivers leading, sometimes, to depression and chronical stress which could last for years and incur additional cost for the family. Hence, dementia diagnosis has an enormous emotional, physical and financial burden for patients, as well as for families. From a financial perspective, the lifetime cost, in 2017, for caring for a patient with Alzheimer’s disease in the USA has been estimated in 341,840 U$ dollars (3). If we take this figure as reference, we can obtain a rough figure for the financial burden produced through the lifetime cost for the 10 million of new dementia patients diagnosed every year worldwide as reported by the world health organization in 2019 (www.who.int/news-room/fact-sheets/detail/dementia). In fact, dementia care already costs around 1% of the world’s gross domestic product, and it is estimated that by the year 2050 the cost of dementia care will go up to 1.1 trillion U$ dollars (3). Importantly, dementia is one among several NCDs that will cost the world in terms of treatment, over the next two decades (2010-2030), about 47 trillion U$ dollars (4). In consequence, identifying factors and pathways involved in NCDs leading to prevention or delaying of disease onset will likely have a major impact on care cost and governmental prevention policies.

Abstract
Chronic postoperative pain is common and can have a negative impact on quality of life. Recent studies show that genetic risk factors are likely to play a role, although only gene‐targeted analysis has been used to date. This is the first genome‐wide association study to identify single‐nucleotide polymorphisms associated with the development of chronic postoperative pain based on two independent cohorts. In a discovery cohort, 330 women scheduled for hysterectomy were genotyped. A case–control association analysis compared patients without chronic postoperative pain and the 34 who had severe chronic postoperative pain 3 months after surgery. No single‐nucleotide polymorphisms reached genome‐wide significance, but several showed suggestive associations with chronic postoperative pain (p < 1 × 10−5). Single‐nucleotide polymorphisms with significance p < 1 × 10−5 were followed up in a replication cohort consisting of 203 men and women scheduled for orthopaedic or abdominal surgery. Ten of these patients developed severe chronic postoperative pain. A single‐nucleotide polymorphism in NAV3 was significantly replicated with chronic postoperative pain in the replication cohort (p = 0.009). Meta‐analysis revealed that two loci (IQGAP1 and CRTC3) were significantly associated with chronic postoperative pain at 3 months (IQGAP1 p = 3.93 × 10−6 β = 2.3863, CRTC3 p = 2.26 × 10−6, β = 2.4209). The present genome‐wide association study provides initial evidence for genetic risk factors of chronic postoperative pain and supports follow‐up studies.

Abstract
Aim: The aim of this study was to explore the relevance of asking young psychiatric patients about childhood symptoms of attention deficit hyperactivity disorder (ADHD).Method: A total of 180 young adults (18-25 years of age) from a general psychiatric out-patient clinic in Uppsala filled in the Child and Adolescent Psychiatric Screening Inventory-Retrospect (CAPSI-R) as part of the diagnostic procedure. The study population was divided into groups based on number and subtype of reported ADHD symptoms, inattention (IN) or hyperactivity/impulsivity (HI). The clinical characteristics associated with different symptoms of ADHD were explored.Results: The groups with five or more self-reported ADHD childhood symptoms, of either IN or HI, had more psychiatric comorbid conditions, a significantly higher co-occurrence of substance use disorders and personality disorders, and experienced more psychosocial and environmental problems.Conclusion: High level of self-reported ADHD childhood symptoms in young psychiatric patients identified a group more burdened with psychiatric comorbid conditions and more psychosocial problems. This group should be offered a thorough diagnostic assessment of ADHD.

Abstract
Abstract
Background
Universities around the world are challenged with rising rates of mental health problems among their students. Cumulative evidence demonstrated that aspects of the social environment, including social capital, play an important role in mental health. This study aimed to determine the prevalence of depressive symptoms among university students from across the globe and to investigate whether social capital was associated with depressive symptoms in university students.
Methods
A cross-sectional study was conducted in Albania, Brazil, Germany, Italy, Malaysia Oman, South Korea, Switzerland, Taiwan and the USA in 2018/2019. Data were obtained through self-administered questionnaire, including questions on sociodemographic characteristics and depressive symptoms. The BDI-S was used to assess the presence of depressive symptoms. Multilevel analyses were conducted to assess the relationship between social capital and depressive, adjusting for individual covariates (e.g. perceived stress and health behaviours) and country-level characteristics (e.g. democracy type).
Results
A total 3894 students participated. Out of all participants almost 47% presented clinically relevant depressive symptoms. The prevalence of depressive symptoms was highest among students identifying as other than male or female (48.7%), among students with low socioeconomic status (59.5%) and among students with low levels of cognitive (65.3%) and behavioural social capital (57.0%). Even after adjustment in multilevel logistic regression analyses, depressive symptoms remained significantly associated with low levels of cognitive social capital (OR = 1.49, 95% CI: 1.06 to 2.10) and low level of behavioural social capital (OR = 1.36, 95% CI: 1.08 to 1.71).
Conclusions
Social capital may play an important role in mental health problems in the university setting. The study identified significant opportunities for future research and health promotion strategies among students.
Key messages
Key factors associated with depressive symptoms among university students were low levels of behavioural and cognitive social capital. Health promotion programs targeting young persons with depressive symptoms should include effective components of social epidemiology such as social capital.

Abstract
Obesity is a public health problem present in both developed and developing countries. The white adipose tissue (WAT) is the main deposit of lipids when there is an excess of energy. Its pathological growth is directly linked to the development of obesity and to a wide number of comorbidities, such as insulin-resistance, cardiovascular disease, among others. In this scenario, it becomes imperative to develop new approaches to the treatment and prevention of obesity and its comorbidities. It has been documented that the browning of WAT could be a suitable strategy to tackle the obesity epidemic that is developing worldwide. Currently there is an intense search for bioactive compounds with anti-obesity properties, which present the particular ability to generate thermogenesis in the brown adipose tissue (BAT) or beige. The present study provide recent information of the bioactive nutritional compounds capable of inducing thermogenesis and therefore capable of generate positive effects on health.

Abstract
Research in solid-gas heterogeneous catalytic processes is typically aimed toward optimization of catalyst composition to achieve a higher conversion and, especially, a higher selectivity. However, even with the most selective catalysts, an upper limit is found: Above a certain temperature, gas-phase reactions become important and their effects cannot be neglected. Here, we apply a microwave field to a catalyst-support ensemble capable of direct microwave heating (MWH). We have taken extra precautions to ensure that (i) the solid phase is free from significant hot spots and (ii) an accurate estimation of both solid and gas temperatures is obtained. MWH allows operating with a catalyst that is significantly hotter than the surrounding gas, achieving a high conversion on the catalyst while reducing undesired homogeneous reactions. We demonstrate the concept with the CO2-mediated oxidative dehydrogenation of isobutane, but it can be applied to any system with significant undesired homogeneous contributions.

Abstract
Abstract
Background. The presence and number of circulating tumor cells (CTCs) are prognostic for breast cancer treatment outcome. Direct imaging assays traditionally employ four markers to identify canonical epithelial CTCs: nucleus, exclusion (CD45), and inclusion (EpCAM and cytokeratin). There is intense interest in the ability to phenotype CTCs in order to provide a noninvasive means by which to predict treatment benefit from endocrine therapy and/or HER2-directed therapy in breast cancer. To address this, a 6-parameter assay for detection of ER and HER2 expression on CTCs was developed. We applied this assay to four well characterized breast cancer cell lines representative of various ER and HER2 phenotypes. Methods. BT474, MCF-7, SKBR3, or MDA-MB-231 cells were spiked into peripheral blood from healthy donors and processed using the AccuCyte® sample preparation system; nucleated cells, including CTCs, are captured onto glass slides (8 slides per 7.5 mL blood sample) for subsequent immunofluorescent staining. Slides were stained using the combined epithelial marker and ER/HER2 CTC assay and then analyzed with the CyteFinder® imaging system. CTCs were identified as nucleated cells with positive EpCAM and/or cytokeratin staining, and negative CD45 staining. ER and HER2 expression were assessed as present or absent. Results. All cell lines expressed both cytokeratin and EpCAM, except for MDA-MB-231 which was EpCAM-negative. The ER / HER2 expression patterns observed were consistent with reported phenotype: BT474 (+/+), MCF-7 (+/–), SKBR3 (–/+), and MDA-MB-231 (–/–). Conclusions. Identification of epithelial CTCs and phenotypic characterization of ER and HER2 status are feasible in a combined assay applied to a single blood sample. This approach has implications for efficiency and cost effectiveness, which are of particular importance given the interest in longitudinal testing. Assay evaluation is currently underway using blood samples from breast cancer patients with known receptor status, treatment history, and clinical outcomes. Results will be available for presentation at the meeting.

Abstract
Adjuvant endocrine hormonal therapy (EHT) is highly effective and appropriate for nearly all breast cancer patients with hormone receptor-positive tumors, which represent 75% of all breast cancer diagnoses. Long-term use of EHT reduces recurrence rates and nearly halves the risk of death during the second decade after diagnosis. Despite the proven benefits, about 33% of women receiving EHT do not take their medication as prescribed. This causes an increase in the risk for recurrence and death. To promote adherence to EHT among breast cancer patients, this study will develop and pilot-test an intervention consisting of 1) a bilingual, culturally tailored, personalized, interactive smartphone application (app); and 2) support from a patient navigator. The control group will receive usual care. This 2-group randomized control trial will recruit 120 breast cancer patients receiving EHT at the Mays Cancer Center at UT Health San Antonio. The two-year study will have 3-time assessments (baseline, 3 and 6 months). This theory-based intervention will empower patients' self-monitoring and management. It will facilitate patient education, identification/reporting of side effects, delivery of self-care advice, and simplify communication between the patient and the oncology team. The ultimate goal of this innovative multi-communication intervention is to improve overall survival and life expectancy, enhance quality of life, reduce recurrence, and decrease healthcare cost. The anticipated outcome is a scalable, evidence-based, and easily disseminated intervention with potentially broad use to patients using EHT and other oral anticancer agents.

Abstract
Tylvalosin (TVN) is a water soluble macrolide used in swine production to treat enteric, respiratory, and arthritic pathogens. There is limited data on its distribution to synovial fluid beyond gavage studies, which do not represent field conditions. This study measured water disappearance, TVN concentration in the medicated water, daily dose, and concentrations of TVN and 3-O-acetyltylosin (3AT) in the synovial fluid and plasma of treated pigs over the administration period. The study emphasized understanding variation in tissue TVN concentrations within the context of a field setting. Sixty finisher pigs were housed individually with individual waterers. Six pigs were randomly allocated to the following time points for sample collection: 0, 48, 60, 72, 84, 96, 102, 108, 114, and 120 hr on medication. TVN was administered daily in the water for 5 days. Water disappearance and medicated water concentration were measured daily. At each time point, six pigs were euthanized and plasma and synovial fluid were collected for analysis. Median TVN synovial fluid concentrations ranged between <1 ng/ml (hour 0) to 3.6 ng/ml (hour 84). There was substantial variation between individual pigs for water disappearance (mean 4.36L and range 0-7.84). Median TVN water concentration was 59 ppm (range 38-75 ppm).

Abstract
AIMS AND METHODTo study the presentation, assessment and management of all patients attending St Thomas' accident and emergency (A&E) department with overt mental health problems. The method included a pragmatic definition of ‘overt mental health problems' and a range of strategies to maximise case ascertainment.RESULTSThe department saw 565 presentations in a 3-month period. Patients were predominantly young, male, single, unemployed, housed outside the area served by the local primary care group and presented outside normal working hours.CLINICAL IMPLICATIONSThis study confirms that A&E departments may be the most frequently used setting for urgent mental health assessments in central London. The patients attending differ from those using community mental health teams. It is argued that mental health liaison services based in inner-city A&E departments should be developed.

Abstract
The European Autism Information System project highlighted the lack of systematic and reliable data relating to the prevalence of autism spectrum disorders in Europe. A protocol for the study of ASD prevalence at European level was developed to facilitate a common format for screening and diagnosing children across the EU. This is the first study to operationalise and screen national school children for ASDs using this protocol. National school children 6-11 years (N = 7951) were screened males 54 % (N = 4268) females 46 % (N = 3683). Screening children for ASD implementing the EAIS protocol using the Social Communication Questionnaire (Rutter et al. in Social Communication Questionnaire (SCQ). Western Psychological Services, Los Angeles, ) as a first level screening instrument in a non-clinical setting of Irish national schools was demonstrated.

Abstract
INTRODUCTION Long term noninvasive continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) are increasingly used in children but limited information is available on the criteria and conditions leading to the initiation of these treatments. The aim of the study is to describe the objective overnight respiratory parameters and clinical situations that led to the initiation of CPAP/NIV in a pediatric NIV unit. MATERIAL AND METHODS Retrospective analysis of the data of all the children discharged on home CPAP/NIV over a 1 year period. RESULTS Seventy-six patients were started on CPAP (n = 64) or NIV (n = 12). CPAP/NIV was initiated because of CPAP/NIV weaning failure (Acute group) in 15 patients. None of these patients had an overnight gas exchange or sleep study before CPAP/NIV initiation. In 18 patients, CPAP/NIV was initiated on abnormal nocturnal gas exchange alone (Subacute group). These patients had a median of three of the following five overnight gas exchange abnormalities: minimal pulse oximetry (SpO2 ) <90%, maximal transcutaneous carbon dioxide (PtcCO2 ) >50 mmHg, time spent with SpO2 <90% or PtcCO2 >50 mmHg ≥2% of recording time, oxygen desaturation index >1.4/hr. In the last 43 patients, CPAP/NIV was initiated after an abnormal sleep study (Chronic group) on a mean of four of the aforementioned criteria and an apnea-hypopnea index >10/hr. CONCLUSION In clinical practice, CPAP/NIV was initiated in an acute, subacute and chronic setting with most patients having an association of several abnormal gas exchange or sleep study parameters. Future studies should evaluate the effectiveness and benefits of CPAP/NIV according to the clinical situation and initiation criteria.

Abstract
Targeting mitotic kinase monopolar spindle 1 (Mps1) for tumor therapy has been investigated for many years. Although it was suggested that Mps1 regulates cell viability through its role in spindle assembly checkpoint (SAC), the underlying mechanism remains less defined. In an endeavor to reveal the role of high levels of mitotic kinase Mps1 in the development of colon cancer, we unexpectedly found the amount of Mps1 required for cell survival far exceeds that of maintaining SAC in aneuploid cell lines. This suggests that other functions of Mps1 besides SAC are also employed to maintain cell viability. Mps1 regulates cell viability independent of its role in cytokinesis as the genetic depletion of Mps1 spanning from metaphase to cytokinesis affects neither cytokinesis nor cell viability. Furthermore, we developed a single-cycle inhibition strategy that allows disruption of Mps1 function only in mitosis. Using this strategy, we found the functions of Mps1 in mitosis are vital for cell viability as short-term treatment of mitotic colon cancer cell lines with Mps1 inhibitors is sufficient to cause cell death. Interestingly, Mps1 inhibitors synergize with microtubule depolymerizing drug in promoting polyploidization but not in tumor cell growth inhibition. Finally, we found that Mps1 can be recruited to mitochondria by binding to voltage-dependent anion channel 1 (VDAC1) via its C-terminal fragment. This interaction is essential for cell viability as Mps1 mutant defective for interaction fails to main cell viability, causing the release of cytochrome c. Meanwhile, deprivation of VDAC1 can make tumor cells refractory to loss of Mps1-induced cell death. Collectively, we conclude that inhibition of the novel mitochondrial function Mps1 is sufficient to kill tumor cells.

Abstract
Glandular trichomes are specialized tissues on the epidermis of many plant species. On tomato they synthesize, store, and emit a variety of metabolites such as terpenoids, which play a role in the interaction with insects. Glandular trichomes are excellent tissues for studying the biosynthesis of specialized plant metabolites and are especially suitable targets for metabolic engineering. Here we describe the strategy for engineering tomato glandular trichomes, first with a transient expression system to provide proof of trichome specificity of selected promoters. Using microparticle bombardment, the trichome specificity of a terpene-synthase promoter could be validated in a relatively fast way. Second, we describe a method for stable expression of genes of interest in trichomes. Trichome-specific expression of another terpene-synthase promoter driving the yellow-fluorescence protein-gene is presented. Finally, we describe a case of the overexpression of farnesyl diphosphate synthase (FPS), specifically in tomato glandular trichomes, providing an important precursor in the biosynthetic pathway of sesquiterpenoids. FPS was targeted to the plastid aiming to engineer sesquiterpenoid production, but interestingly leading to a loss of monoterpenoid production in the transgenic tomato trichomes. With this example we show that trichomes are amenable to engineering though, even with knowledge of a biochemical pathway, the result of such engineering can be unexpected.

Abstract
Neurotoxicity due to the accumulation of mutant proteins is thought to drive pathogenesis in neurodegenerative diseases. Mutations in superoxide dismutase 1 (SOD1) are linked to familial amyotrophic lateral sclerosis (fALS); these mutations result in progressive motor neuron death through one or more acquired toxicities. Interestingly, SOD1 is not only responsible for fALS but may also play a significant role in sporadic ALS; therefore, SOD1 represents a promising therapeutic target. Here, we report slowed disease progression, improved neuromuscular function, and increased survival in an in vivo ALS model following therapeutic delivery of morpholino oligonucleotides (MOs) designed to reduce the synthesis of human SOD1. Neuropathological analysis demonstrated increased motor neuron and axon numbers and a remarkable reduction in astrogliosis and microgliosis. To test this strategy in a human model, we treated human fALS induced pluripotent stem cell (iPSC)-derived motor neurons with MOs; these cells exhibited increased survival and reduced expression of apoptotic markers. Our data demonstrated the efficacy of MO-mediated therapy in mouse and human ALS models, setting the stage for human clinical trials.
