    Seals and humans often target the same food resource, leading to competition. This is of mounting concern with fish stocks in global decline. Grey seals were tracked from southeast Ireland, an area of mixed demersal and pelagic fisheries, and overlap with fisheries on the Celtic Shelf and Irish Sea was assessed. Overall, there was low overlap between the tagged seals and fisheries. However, when we separate active (e.g. trawls) and passive gear (e.g. nets, lines) fisheries, a different picture emerged. Overlap with active fisheries was no different from that expected under a random distribution, but overlap with passive fisheries was significantly higher. This suggests that grey seals may be targeting the same areas as passive fisheries and/or specifically targeting passive gear. There was variation in foraging areas between individual seals suggesting habitat partitioning to reduce intra-specific competition or potential individual specialisation in foraging behaviour. Our findings support other recent assertions that seal/fisheries interactions in Irish waters are an issue in inshore passive fisheries, most likely at the operational and individual level. This suggests that seal population management measures would be unjustifiable, and mitigation is best focused on minimizing interactions at nets

    Supporting autonomy for people with dementia living in nursing homes:A rapid realist review

    Get PDF
    Background For people with dementia living in nursing homes, autonomy is important. However, they experience difficulty with being heard as an autonomous person, as well as with expressing their preferences and choices. The question is how to support their autonomy. Objective Despite extensive efforts to support autonomy in daily care for people with dementia living in nursing homes, we do not know exactly what works for whom, in which context, how and why. The objective of this realist review is to explore what is known in literature on autonomy support interventions for people with dementia in nursing homes. Design A rapid realist review of literature. Review methods To understand how autonomy is supported, a realist approach was applied that entailed identifying the research question, searching for information, performing a quality appraisal, extracting data, synthesizing the evidence and validating the findings with a panel of experts. Causal assumptions were derived from articles found in four bibliographic databases (PubMed, PsychInfo, Cochrane and CINAHL) leading to context (C)–mechanism (M)–outcome (O) configurations. Results Data extraction from the included articles ultimately resulted in sixteen CMO configurations on four themes: a. preferences and choice: interventions for supporting autonomy in nursing homes and their results, b. personal characteristics of residents and family: people with dementia and their family being individuals who have their own character, habits and behaviors, c. competent nursing staff each having their own level of knowledge, competence and need for support, and d. interaction and relationships in care situations: the persons involved are interrelated, continuously interacting in different triangles composed of residents, family members and nursing staff. Conclusion The findings showed that results from interventions on autonomy in daily-care situations are likely to be just as related not only with the characteristics and competences of the people involved, but also to how they interact. Autonomy support interventions appear to be successful when the right context factors are considered

    Objective To construct a patient- and user-friendly shortened version of the Geriatric Depression Scale (GDS) that is especially suitable for nursing home patients. Methods The study was carried out on two different data bases including 23 Dutch nursing homes. Data on the GDS (n¼410), the Mini Mental State Examination (n¼410) and a diagnostic interview (SCAN; n¼333), were collected by trained clinicians. Firstly, the items of the GDS-15 were judged on their clinical applicability by three clinical experts. Subsequently, items that were identified as unsuitable were removed using the data of the Assess project (n¼77), and internal consistency was calculated. Secondly, with respect to criterion validity (sensitivity, specitivity, area under ROC and positive and negative predictive values), the newly constructed shortened GDS was validated in the AGED data set (n¼333), using DSM-IV diagnosis for depression as measured by the SCAN as ‘gold standard’. Results The eight-item GDS that resulted from stage 1 showed good internal consistency in both the Assess data set (a¼0.86) and the AGED dataset (a¼0.80). In the AGED dataset, high sensitivity rates of 96.3% for major depression and 83.0% for minor depression were found, with a specificity rate of 71.7% at a cut-off point of 2/3. Conclusion The GDS-8 has good psychometric properties. Given that the GDS-8 is less burdening for the patient, more comfortable to use and less time consuming, it may be a more feasible screening test for the frail nursing home population

    Dental Laboratory Production of Prosthetic Restorations in a Population in Sofia, Bulgaria: A Descriptive Study

    Get PDF
    Objective. To describe prosthodontic production related to mutilated dentitions in Sofia, Bulgaria. Methods. Prosthodontic production from 5 dental laboratories was recorded during a 14-day period. Production was related to dentitions as noted from casts. Dentitions were classified as edentulous, interrupted/reduced, slightly interrupted, shortened, and complete. The representativeness of the laboratory sample was verified trough comparison with a Sofia population sample using proportions of crowned or replaced teeth per dental region. Results. The total production consisted of 243 crowns, 16 post and cores, 82 fixed dental prostheses, and 41 removable dentures. Proportions of crowned teeth were significantly different between the samples; proportions of replaced teeth were not. Of the 58 incomplete dentitions analyzed, 19 were restored to the level of completeness, 15 resulted in slightly interrupted, and 24 in shortened dentitions. Conclusions. Predominantly fixed restorations were provided to restore mutilated dentitions to a functional level and not necessarily to complete dentitions

    Breath of Life: The Respiratory Vagal Stimulation Model of Contemplative Activity

    Get PDF
    Contemplative practices, such as meditation and yoga, are increasingly popular among the general public and as topics of research. Beneficial effects associated with these practices have been found on physical health, mental health and cognitive performance. However, studies and theories that clarify the underlying mechanisms are lacking or scarce. This theoretical review aims to address and compensate this scarcity. We will show that various contemplative activities have in common that breathing is regulated or attentively guided. This respiratory discipline in turn could parsimoniously explain the physical and mental benefits of contemplative activities through changes in autonomic balance. We propose a neurophysiological model that explains how these specific respiration styles could operate, by phasically and tonically stimulating the vagal nerve: respiratory vagal nerve stimulation (rVNS). The vagal nerve, as a proponent of the parasympathetic nervous system (PNS), is the prime candidate in explaining the effects of contemplative practices on health, mental health and cognition. We will discuss implications and limitations of our model

    Evaluation of two strategies to implement physical cancer rehabilitation guidelines for survivors of abdominopelvic cavity tumors:a controlled before-and-after study

    PURPOSE: This study evaluates the effectiveness and feasibility of two strategies to implement physical cancer rehabilitation (PCR) guidelines for patients who have survived abdominopelvic cavity malignancies. METHODS: We tested and compared two tailored strategies to implement PCR guidelines for survivors of gastrointestinal, female organ and urogenital organ malignancies, in a clustered controlled before-and-after study. A patient-directed (PD) strategy was tested in five cancer centers, aiming to empower survivors. A multifaceted (MF) strategy was tested in four cancer centers, aiming additionally to influence healthcare professionals and the healthcare organization. Data were collected from existing registration systems, patient questionnaires and professional questionnaires. We measured both implementation- and client outcomes. For insight into the effectiveness we measured indicators related to PCR guidelines: (1) screening with the Distress Thermometer (DT) (=primary outcome measure), (2) information provision concerning physical activity (PA) and physical cancer rehabilitation programs (PCRPs), (3) advice to take part in PA and PCRPs, (4) referral to PCRPs, (5) participation in PCRPs, (6) PA uptake (PAU); and patient reported outcomes (PROs) such as (7) quality of life, (8) fatigue, and (9) empowerment. Furthermore, survivor and center determinants were assessed as possible confounders. Multilevel analyses were performed to compare the scores of the indicators of the PD and MF strategies, as well as the differences between the characteristics of these groups. The use of and experiences with both strategies were measured using questionnaires and Google Analytics to assess feasibility. RESULTS: In total, 1326 survivors participated in the study, 673 in the before- and 653 in the after-measurement. Regarding our primary outcome measure, we found a significant improvement of screening with the DT between the before- and after-measurement for both strategies, respectively from 34.2 to 43.1% (delta=8.9%; odds ratio (OR)=1.6706; p=0.0072) for the PD strategy and from 41.5 to 56.1% (delta=14.6%; OR=1.7098; p=0.0028) for the MF strategy. For both the primary and secondary outcomes, no statistically significant effect of the MF strategy compared to the PD strategy was observed. We found good use of and positive experiences with both strategies. CONCLUSION: Implementation strategies containing tools enhancing patient empowerment seem to be effective in increasing the systematic screening with the DT for survivors of abdominopelvic cavity malignancies. Further research is needed to assess the additional effectiveness of strategies that stimulate compliance among healthcare professionals and healthcare organizations. IMPLICATIONS FOR CANCER SURVIVORS: Using implementation strategies containing tools enhancing patient empowerment seem to be effective in increasing the systematic screening with the DT and might improve the quality of care of patients who have survived abdominopelvic cavity malignancies.

    BackgroundNovel second-line treatments are needed for patients with advanced urothelial cancer (UC). Interim analysis of the phase III KEYNOTE-045 study showed a superior overall survival (OS) benefit of pembrolizumab, a programmed death 1 inhibitor, versus chemotherapy in patients with advanced UC that progressed on platinum-based chemotherapy. Here we report the long-term safety and efficacy outcomes of KEYNOTE-045.Patients and methodsAdult patients with histologically/cytologically confirmed UC whose disease progressed after first-line, platinum-containing chemotherapy were enrolled. Patients were randomly assigned 1 : 1 to receive pembrolizumab [200 mg every 3 weeks (Q3W)] or investigator's choice of paclitaxel (175 mg/m2 Q3W), docetaxel (75 mg/m2 Q3W), or vinflunine (320 mg/m2 Q3W). Primary end points were OS and progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) by blinded independent central radiology review (BICR). A key secondary end point was objective response rate per RECIST v1.1 by BICR.ResultsA total of 542 patients were enrolled (pembrolizumab, n = 270; chemotherapy, n = 272). Median follow-up as of 26 October 2017 was 27.7 months. Median 1- and 2-year OS rates were higher with pembrolizumab (44.2% and 26.9%, respectively) than chemotherapy (29.8% and 14.3%, respectively). PFS rates did not differ between treatment arms; however, 1- and 2-year PFS rates were higher with pembrolizumab. The objective response rate was also higher with pembrolizumab (21.1% versus 11.0%). Median duration of response to pembrolizumab was not reached (range 1.6+ to 30.0+ months) versus chemotherapy (4.4 months; range 1.4+ to 29.9+ months). Pembrolizumab had lower rates of any grade (62.0% versus 90.6%) and grade ≥3 (16.5% versus 50.2%) treatment-related adverse events than chemotherapy.ConclusionsLong-term results (>2 years' follow-up) were consistent with those of previously reported analyses, demonstrating continued clinical benefit of pembrolizumab over chemotherapy for efficacy and safety for treatment of locally advanced/metastatic, platinum-refractory UC.Trial registrationClinicalTrials.gov: NCT02256436

    Variation in pathogenicity of recombinations of Heterarhabditis and Xenarhabdus luminescens strains

    Surnrnary -Xeoorhabdus luminescens isolates were exchanged between four insect pathogenic nematode strains : two different Heterorhabditis isolates from the Netherlands and two different Heterorhabditis baeteriophora isolates. Of the sixteen possible combinations three combinations, ofDutch nematodes with bacteria of H. bacteriophora, were not able to grow and multiply. Of the thirteen combinations that could be propagated the four combinations of H. bacteriopJwra nematodes with bacteria from the Dutch nematodes were not pathogenic. When waxmoth larvae were in;ected with bacteria, the four non-pathogenic combinations were able to penetrate and multiply in these larvae. This showed that the lack of pathogeniciry of these four combinations was due to the absence ofbacteria. Both H. bacteriophora strains penetrated insect larvae in lower numbers than both Dutch Heterorhabditis strains, independent what bacteriurn they were carrying. Résumé
