Abstract
Disturbances in the sleep-wake cycle are a debilitating, yet rather common condition not only in humans, but also in family dogs. While there is an emerging need for easy-to-use tools to document sleep alterations (in order to ultimately treat and/or prevent them), the veterinary tools which yield objective data (e.g. polysomnography, activity monitors) are both labor intensive and expensive. In this study, we developed a modified version of a previously used sleep questionnaire (SNoRE) and determined criterion validity in companion dogs against polysomnography and physical activity monitors (PAMs). Since a negative correlation between sleep time and cognitive performance in senior dogs has been demonstrated, we evaluated the correlation between the SNoRE scores and the Canine Dementia Scale (CADES, which includes a factor concerning sleep). There was a significant correlation between SNoRE 3.0 questionnaire scores and polysomnography data (latency to NREM sleep, ρ = 0.507, p < 0.001) as well as PAMs' data (activity between 1:00 and 3:00 AM, p < 0.05). There was a moderate positive correlation between the SNoRE 3.0 scores and the CADES scores (ρ = 0.625, p < 0.001). Additionally, the questionnaire structure was validated by a confirmatory factor analysis, and it also showed an adequate test-retest reliability. In conclusion the present paper describes a valid and reliable questionnaire tool, that can be used as a cost-effective way to monitor dog sleep in clinical settings.

Abstract
BackgroundVaccination is considered efficient in controlling infections incl. SARS-CoV-2. Prior studies showed that patients receiving rituximab (RTX) with low B cell counts are at increased infectious risk (1) and risk of inadequate vaccination responses (2, 3). Thus, the ability to further define and predict vaccination responses in these patients may guide their optimal protection.ObjectivesTo assess predictive biomarkers of vaccination responses upon SARS-CoV-2 vaccination in RTX treated patients.MethodsB cell characteristics before vaccination were evaluated to predict responses in 15 patients with autoimmune inflammatory rheumatic diseases receiving RTX. 11 patients with rheumatoid arthritis on other therapies (RA), 11 kidney transplant recipients (KTR) and 15 healthy volunteers (HC) served as controls. A multidimensional analysis of B cell subsets and a correlation matrix were performed to identify predictive biomarkers.ResultsSignificant differences regarding absolute B cell counts and specific subset distribution pattern between the groups were validated at baseline. Here, the majority of B cells from vaccination responders of the RTX group (RTX IgG+) comprised naïve and transitional B cells, whereas vaccination non-responders (RTX IgG-) carried preferentially plasmablasts and double negative (CD27-IgD-) B cells (Figure 1). Moreover, there was a positive correlation between neutralizing antibodies and absolute B cell numbers with B cells expressing HLA-DR and CXCR5 (involved in antigen presentation and germinal center formation) as well as an inverse correlation with CD95 expression and CD21low expression (marker for activation and exhaustion) on B cells.ConclusionSubstantial repopulation of naïve B cells upon RTX therapy appears to be essential for an adequate vaccination response requiring germinal center formation. In contrast, expression of exhaustion markers (CD21low, CXCR5-, CD95+) indicate negative predictors of vaccination responses. These results may guide optimized vaccination strategies in RTX treated patients clearly requiring antigen-inexperienced B cells for appropriate protection.References[1]Sparks JA, Wallace ZS, Seet AM, Gianfrancesco MA, Izadi Z, Hyrich KL, et al.

Abstract
Introduction Schizoaffective disorder is a psychotic disorder of controversial nosological entity. Affective symptomatology and psychotic features of varying intensity coexist simultaneously in him throughout evolution. The lack of consensus on the existence of this entity determines its diagnostic delay and the absence of specific treatment guidelines. Objectives To review the diagnostic criteria for schizoaffective disorder and the published scientific evidence on the efficacy and safety of the different therapeutic options available. To analyze the efficacy of a multidisciplinary treatment plan implemented in an intensive follow-up program, presenting the evolution of a clinical case. Methods To review the psychiatric history and psychopathological evolution of a patient diagnosed with schizoaffective disorder from the beginning of an intensive follow-up program in a day center to the present. Review the existing scientific evidence on the usefulness of the treatments used in this nosological entity. Results This is a longitudinal and retrospective study of a clinical case in which the areas for improvement are analyzed before implementing a multidisciplinary therapeutic program and the favorable results obtained today. Currently, the patient is euthymic and attenuated and chronic positive and negative symptoms persist that do not interfere with his functionality. Conclusions From the implementation of an individualized, personalized and multidisciplinary maintenance treatment plan, an overall improvement in psychopathological stability and functional recovery is observed. Among the psychopharmacological options in this patient, Paliperidone Long Acting Injection (PLAI) stands out for its long-term efficacy and safety.

Abstract
There is growing interest in harnessing the genetic and adaptive diversity of crop wild relatives to improve drought resilience of elite cultivars. Rainfall gradients exert strong selection pressure on both natural and agricultural ecosystems. Understanding plant responses to these facilitates crop improvement. Wild and domesticated narrow-leafed lupin (NLL) collected along Mediterranean terminal drought stress gradients was evaluated under contrasting reproductive phase water supply in controlled field, glasshouse and cabinet studies. Plant phenology, growth and productivity, water use and stress responses were measured over time. There is an integrated suite of adaptive changes along rainfall gradients in NLL. Low rainfall ecotypes flower earlier, accumulate lower seed numbers, biomass and leaf area, and have larger root:shoot ratios than high rainfall ecotypes. Water-use is lower and stress onset slower in low compared to high rainfall ecotypes. Water-use rates and ecotypic differences in stress response (Ψleaf decline, leaf loss) are lower in NLL than yellow lupin (YL). To mitigate the effects of profligate water use, high rainfall YL ecotypes maintain higher leaf water content over declining leaf water potential than low rainfall ecotypes. There is no evidence for such specific adaptation in NLL. The data suggests that appropriate phenology is the key adaptive trait to rainfall gradients in NLL because of the flow-on effects on biomass production, fitness, transpiration and stress onset, and the lack of physiological adaptations as in YL. Accordingly, it is essential to match phenology with target environment in order to minimize risk and maximize yield potential.

Abstract
The treatment of tracheopleural and bronchopleural fistulas at an anastomosis after sleeve resection is complex and fraught with complications. Morbidity and mortality are very high. Therefore, great care must be taken to avoid such complications. The clinical signs and the early diagnosis of a potentially critical anastomosis or anastomotic leakage as well as the treatment, including secondary pneumonectomy are presented.

Abstract
Introduction The pan-Canadian Oncology Symptom Triage and Remote Support (costars) team is studying how to improve the quality and consistency of cancer symptom management. Methods A 1-day invitational meeting was held 24 October 2017 in Ottawa, Ontario, to review the current evidence from costars projects and to establish research priorities for a future largescale implementation study. The meeting included 36 participants who were clinicians from adult oncology, pediatric oncology, and homecare; policymakers from national, provincial, and regional organizations; researchers; and a patient. Half the day involved summarizing evidence from four costars studies and experiences with implementing the costars symptom practice guides. The second half of the day used a modified nominal group technique to generate research questions within small groups, presentation of research questions to all participants, and two rounds of voting to reach consensus on research priorities. Results Participants proposed 4 research categories:■ User-centred augmentation to enhance usability (for example, designing a mobile costars solution)■ Outcome measurement (for example, determining key competencies for clinicians)■ Regular renewal of costars to keep pace with evolving evidence (for example, updates for novel therapies)■ Integration into clinical practice (for example, meaningful engagement of patients and caregivers in study design). Conclusions Across categories, the top 3 priorities were effect on health services use, competency development, and a mobile costars solution. Future research will address identified priorities, reflecting the needs and perspectives of diverse stakeholders. Stakeholder collaboration will continue to guide our approach to operationalizing this priority research agenda.

Abstract
Background Radiation therapists play an important role in helping patients to safely manage and triage potentially life-threatening symptoms. The purpose of the present study was to assess factors influencing the use by radiation therapists of evidence-informed symptom practice guides for patients experiencing cancer treatment–related symptoms.Methods In a mixed-methods descriptive study guided by the Knowledge-to-Action framework, interviews and a barriers survey were conducted. Two independent reviewers conducted a content analysis of interview transcripts. Barriers survey data were analyzed using frequency distributions and univariate descriptive statistics. Open-ended data from the surveys underwent content analysis and were triangulated with interview findings.Results Of 90 radiation therapists approached, 58 completed the survey (64%), and 14 were interviewed. Of the 98% who reported providing symptom management to patients undergoing radiation treatment, 53% used evidence-informed practice guidelines. Radiation therapists had moderate moral norms (4.6 of 7) and beliefs about the consequences of using costars (pan Canadian Oncology Symptom Triage and Remote Support) practice guides (4.8), but neutral intention (3.4) and beliefs about their own capabilities (3.9). Environmental barriers included lack of time (2.0), lack of access (2.5), and neutral organizational support (3.0). Radiation therapists identified a need for training (5.5). Common unique barriers to practice guide use were lack of time during radiation treatments, unclear fit with scope of practice, disparate focus on site-specific symptoms, and lack of medication knowledge.Conclusions The symptom practice guides were perceived by the radiation therapists to benefit patients, enhance their own knowledge of symptom management, and promote consistent practice. Additional work is required to identify the scope of practice of radiation therapists within the interprofessional team.

Abstract
PURPOSE Regarding the epidemiology of pain in older adults, data are lacking about the association between pain severity and its impact on health-related quality of life (HRQoL). This study was aimed to investigate pain prevalence and sites, self-reported interferences with daily life activities, and the effect of pain severity on HRQoL in a Swiss community-dwelling population aged ≥ 65 years. METHODS This is a cross-sectional survey conducted with a national sample of individuals randomly selected from population records, stratified by age and gender. Respondents answered a face-face interview addressing pain location, intensity and interferences, and quality-of-life variables. Logit regression models were applied for binary outcomes, linear regression for continuous outcomes, and Poisson regression for count outcomes. For each analysis, Wald Chi square and 95% confidence intervals were used. RESULTS Among the 2995 individuals considered, 36.4% reported pain. The results indicate that pain prevalence and intensity increased from age 80 onwards. Pain intensity was strongly associated with functional health, i.e., all scales involving physical activities were affected in individuals reporting severe pain; it was also associated with the individuals' perception of their overall HRQoL. CONCLUSION Our results point to the importance of devoting attention to pain intensity rather than to the number of pain sites. Because of the demographic transition, the management of pain problems should emphasize early referral and timely treatment to prevent the burden of disease and functional loss associated with pain intensity.

Abstract
PURPOSE The present study aims at investigating the effects of low back pain (LBP), i.e., type of symptoms, activity limitations, frequency, duration, and severity on health-related quality of life (HRQoL) in a sample of 707 community-dwelling men and women aged ≥ 65 years living in Switzerland. METHODS The study is part of a larger survey conducted in Switzerland on a sample of older adults selected randomly from population records, stratified by age and sex. The Standardized Back Pain Definition was used to investigate LBP, and HRQoL was assessed by means of the EQ-5D, including Health Utility Index (HUI) measures. RESULTS For more than half of the sufferers, pain was chronic, occurred most days or every day and induced activity limitations. One-third of the sufferers reported sciatica symptoms. Individuals reporting every day pain, severe pain and more than 3 years since the last episode without pain lost nearly 10 points of HRQoL. Amongst the dimension of HRQoL, Mobility was the most affected by LBP. CONCLUSIONS These results provide further insight into the impact of qualitative aspects of LBP and in particular the importance of radiating leg pain and pain frequency and duration. While LBP-related activity limitations had little impact on both self-rated overall health and HUI, radiating leg pain and pain frequency and duration were associated with significantly decreased scores on both dimensions.

Abstract
BACKGROUND Penetrating injuries are rare in European populations so their management represents a particular challenge. The aim was to assess early therapeutic aspects that are associated with favourable outcomes in patients with penetrating trauma. METHODS Patients with penetrating injuries documented from 2009 to 2013 in the TraumaRegister DGU® were analysed. Patients with a primary admission and an Injury Severity Score (ISS) of at least 9 were included. The Revised Injury Severity Classification (RISC) II score was used for mortality prediction, and a standardized mortality ratio (SMR) calculated per hospital. Hospitals with favourable outcome (SMR below 1) were compared with those with poor outcome (SMR 1 or more). RESULTS A total of 50 centres had favourable outcome (1242 patients; observed mortality rate 15.7 per cent) and 34 centres had poor outcome (918 patients; observed mortality rate 24.4 per cent). Predicted mortality rates according to RISC-II were 20.4 and 20.5 per cent respectively. Mean(s.d.) ISS values were 22(14) versus 21(14) (P = 0.121). Patients in the favourable outcome group had a significantly shorter time before admission to hospital and a lower intubation rate. They received smaller quantities of intravenous fluids on admission to the emergency room, but larger amounts of fresh frozen plasma, and were more likely to receive haemostatic agents. A higher proportion of patients in the favourable outcome group were treated in a level I trauma centre. Independent risk factors for hospital death following penetrating trauma identified by multivariable analysis included gunshot injury mechanism and treatment in non-level I centres. CONCLUSION Among penetrating traumas, gunshot injuries pose an independent risk of death. Treatment of penetrating trauma in a level I trauma centre was significantly and independently associated with lower hospital mortality.

Abstract
Sleeve resection comprises 3.1 % to 27.7 % of all anatomic lung resections performed in Germany. Anastomotic insufficiency is a feared complication that should be avoided. When anastomotic insufficiency does lead to secondary pneumonectomy, postoperative morbidity and mortality is high (30 % to 80 %). It is therefore very important to standardize the technique of sleeve resection as well as postoperative care. The time-point of postoperative follow-up and the interpretation of endobronchial healing have not yet been defined. In this paper anastomotic healing is described and interpreted with the help of a 5-step classification that allows bronchoscopic evaluation and classification of the anastomosis. The aim is to provide a standardized algorithm for postoperative care after sleeve resection. The basis of this classification and postoperative care measures derived from it are described and illustrated with the help of clinical examples.

Abstract
BACKGROUND The most common long-term complication of tracheotomy is the benign stenosis of the trachea, which is described for up to 20% of the cases. Typically, the stenosis occurs after decannulation in the context of secondary wound healing. This study examined whether the closure of the tracheostomy by surgical procedure reduces stenosis. METHOD With the help of our clinical database a retrospective analysis of 401 surgical tracheotomies was performed. Variables that were recorded were the indication for tracheotomy, the clinical course and complications occurred. RESULTS 155 patients were successfully decannulated. In 92 of these patients the tracheostomy was closed by a surgical procedure, in 63 cases the closure occurred spontaneously by wound healing. After decannulation 3% (n=3) of the surgically closed and 22% (n=14) of the spontaneously closed tracheostomies developed a symptomatic tracheal stenosis (p<0.001). CONCLUSION Secondary wound healing of the tracheostomy often leads to symptomatic tracheal stenosis. The incidence of symptomatic tracheal stenosis was significantly reduced applying closure of the tracheostomy by surgical procedure.

Abstract
Visceral leishmaniasis is an enzootic parasitosis present across the Mediterranean Basin. Some consider it an opportunistic parasite. We report the case of a girl treated with anti-tumour necrosis factor alpha (anti-TNFα) for juvenile idiopathic arthritis who had previously presented with visceral leishmaniasis. Two and a half years later, she presented a tumour-like mass in the nasal mucous membrane caused by Leishmania parasites. Leishmania infantum is classically responsible for visceral leishmaniasis, but pure mucocutaneous leishmaniasis has also been described. To our knowledge, this is the first observation of a recurrence of visceral leishmaniasis in the mucocutaneous form. The occurrence of atypical forms and presentations in those on anti-TNF therapy should be considered.

Abstract
Our understanding of within-species annual plant adaptation to rainfall gradients is fragmented. Broad-scale ecological applications of Grime's C-S-R triangle are often superficial, while detailed drought physiology tends to be narrow, focusing on elite cultivars. The former lack the detail to explain how plants respond, while the latter provide little context to investigate trade-offs among traits, to explain where/why these might be adaptive. Ecophysiology, combining the breadth of the former with the detail of the latter, can resolve this disconnect and is applied here to describe adaptive strategies in the Mediterranean legume Lupinus luteus. Wild and domesticated material from low- and high-rainfall environments was evaluated under contrasting terminal drought. These opposing environments have selected for contrasting, integrated, adaptive strategies. Long-season, high-rainfall habitats select for competitive (C) traits: delayed phenology, high above- and below-ground biomass, productivity, and fecundity, leading to high water-use and early stress onset. Terminal drought-prone environments select for the opposite: ruderal (R) traits that facilitate drought escape/avoidance but limit reproductive potential. Surprisingly, high-rainfall ecotypes generate lower critical leaf water potentials under water deficit, maintaining higher relative water content than the latter. Given that L. luteus evolved in sandy, low-water-holding capacity soils, this represents a bet-hedging response to intermittent self-imposed water-deficits associated with a strongly C-selected adaptive strategy that is therefore redundant in R-selected low-rainfall ecotypes. Domesticated L. luteus is even more R-selected, reflecting ongoing selection for early maturity. Introgression of appropriate C-selected adaptive traits from wild germplasm may widen the crop production range.

Abstract
Lung cancer is a leading cause of cancer related death worldwide. Non-small cell lung cancer (NSCLC) represents 85 % of all lung cancer cases and approximately 40 % of all patients impress with a metastatic disease at the time of diagnosis. Stage IV NSCLC has a poor prognosis and is incurable. The recommended standard therapy in this case is a palliative supportive systemic chemotherapy. However, a distinctive subgroup of patients with stage IV NSCLC appear clinically with an oligometastatic disease and may qualify for surgical therapy. There is evidence that patients with synchronous or metachronus solitary satellite nodules, either located intrapulmonary or extrapulmonary, benefit from surgical resection.

Abstract
The non-invasive measurement of adrenocortical function in cheetahs is an important tool to assess stress in captive and free-ranging individuals, because stress has been suggested to be one of the causes of poor reproductive performance of captive cheetahs. We tested four enzyme immunoassays (EIA) in two captive cheetahs in Germany using adrenocorticotropic hormone (ACTH) challenges and identified the corticosterone-3-CMO EIA to be most sensitive to the increase in faecal glucocorticoid metabolite (fGCM) concentrations after the ACTH challenge. This EIA performed also well in five captive cheetahs in South Africa. The fGCM concentrations across all seven cheetahs increased within 24h by 681% compared to the baseline levels prior to ACTH. Storage of faecal samples at 0-4°C did not strongly affect fGCM concentrations within 24h, simplifying sample collection when immediate storage at -20°C is not feasible. The two cheetahs in Germany also received an injection of [(3)H]cortisol to characterise fGCMs in faecal extracts using high-performance liquid chromatography (HPLC) immunograms. HPLC fractions were measured for their radioactivity and immunoreactive fGCM concentrations with the corticosterone-3-CMO EIA, respectively. The results revealed a polar peak of radiolabelled cortisol metabolites co-eluting with the major peak of immunoreactive fGCMs. Thus, our EIA measured substantial amounts of fGCMs corresponding to the radioactive peaks. The peaks were of higher polarity than native cortisol and corticosterone, suggesting that the metabolites were conjugated, which was confirmed by solvolysis of the HPLC fractions. Our results show that the corticosterone-3-CMO EIA is a reliable tool to assess fGCMs in cheetahs.

Abstract
Eleven non-invasive and 24 invasive transitional cell bladder cancers were analysed for molecular alterations to the p53 gene and nuclear accumulation of the p53 protein. 9% (1/11) of non-invasive rumours and 21% (5/24) of invasive tumours revealed nuclear accumulation in more than 50% of the tumour cells. PCR analysis of D17S30 showed loss of heterozygosity (LOH) in invasive tumours (3/24; 12%). Two invasive tumours harboured point mutations in exon 6 and exon 7, respectively (8%). Our results indicate that p53 protein overexpression correlates with tumour progression, p53 gene mutations and LOH detected by PCR.
