Unspoken expectations and situational participation: a qualitative study exploring the instantiation of next of kin involvement within the trust model.

BACKGROUND: Demographic changes, such as an increase in older adults, present a challenge to the healthcare service's current capacity. Moreover, the need for healthcare personnel is rising, while the availability of labour is dwindling, leading to a potential workforce shortage. To address some of these challenges, enhanced collaboration between home-based healthcare frontline workers, service users, and next of kin is a necessity. The trust model is an organisational model where home-based healthcare services are organised into smaller interdisciplinary teams aiming to tailor the services in collaboration with service-users and their next of kin'. This study explores how the next of kin and frontline workers perceive and perform involvement in making decisions regarding tailoring the services for the users of home-based healthcare services organised after the trust model. METHODS: Four in-depth interviews and 32 observations were conducted, and thematic analysis was employed to identify meaningful patterns across the datasets. RESULTS: The results are presented as two themes: (i) unspoken expectations and (ii) situational participation. The results highlight the complex nature of next-of-kin involvement and shared decision making, raising questions about meeting expectations, evaluating available resources, and developing sustainable involvement processes. CONCLUSION: This study indicates that despite of an interdisciplinary organisational model aiming for shared decision making as the trust model, the involvement of next of kin continues to be a challenge for frontline workers in home-based healthcare services. It also points to the importance of transparent communication and how it is deemed essential for clarifying implicit expectations.

Interdisciplinary frontline teams in home-based healthcare services-paradoxes between organisational work structures and the trust model: a qualitative study.

BACKGROUND: Achieving access to quality healthcare services to ensure healthy lives and promote well-being for all at all ages is one of the United Nation's Sustainable Developments Goals. In view of this goal, sustainable community healthcare services in Norway need to be urgently restructured in light of demographic changes, including an increase in the percentage of older adults in the country. National healthcare policies recommend finding new ways to organise and perform services using new technology, new methods and new solutions. The goal is to ensure greater continuity in the provision of services and softer transitions that enable service users to deal with a smaller number of people. The trust model is one such suggested organisational approach. The goal of the trust model is to involve service users and their next of kin in decisions that concern them while also trusting frontline workers' professional judgement in assessing the need for services and adjusting them to address changes in the health of the users, thus making the services individually tailored and more flexible. This study aims to explore how organisational work structures influence the delivery of interdisciplinary home-based healthcare services. METHODS: Observations, individual-, and focus groups interviews were conducted within community home-based healthcare services in a large Norwegian city with managers at different levels, nurses, occupational therapists, physiotherapists, purchaser-unit employees and other healthcare workers. Data was analysed thematically. RESULTS: The results are presented in terms of themes- "Balancing on the margins: Negotiations between the time available, users' needs, unforeseen events and administrative tasks" and "One gathered unit, but with different work structures". The results identify organisational work structures that influence the performance of the trust model with regard to its intention of making flexible and individually tailored services available. However, these structures are different for the members of the interdisciplinary team, thus creating several paradoxes that need to be negotiated while fulfilling their daily responsibilities. CONCLUSION: This study suggests that it is crucial to pay attention to paradoxes and structures experienced by interdisciplinary frontline workers in home-based healthcare services, since they are unavoidable factors that need to be acknowledged when designing approaches for addressing the changes expected in community healthcare services.

Occupational Therapy Interventions for Persons with Cognitive Impairments Living in the Community.

This study describes interventions provided by community occupational therapists for persons with cognitive impairments. Using an online questionnaire, a cross-sectional study was conducted, collecting data from 497 of the 1367 occupational therapists in Norwegian community-based services. The most common interventions provided were environmental modifications (87%), implementation of assistive devices (85%), and training of activities of daily life (ADL) (77%). Two main reasons to carry out these interventions were identified as the initial assessment of clients (89%) and expectations of others. The most preferred interventions were ADL training (77%), cognitive training (63%), and environmental modifications (56%). Chi-squared tests identified a significant difference (p < 0.001) between interventions provided and preferred interventions on all interventions except environmental modifications. The findings provide an insight into interventions provided for persons with cognitive impairments in community services.

Associations between unmet needs for daytime activities and company and scores on the Neuropsychiatric Inventory-Questionnaire in people with dementia: a longitudinal study.

OBJECTIVES: To examine prospectively the association between unmet needs for daytime activities and company and behavioural and psychological symptoms of dementia. METHODS: We included 451 people with mild or moderate dementia, from eight European countries, who were assessed three times over 12 months. Unmet needs were measured with the Camberwell Assessment of Need for the Elderly. Three sub-syndromes of the Neuropsychiatric Inventory-Questionnaire were regressed, one-by-one, against unmet needs for daytime activities and company, adjusting for demographic and clinical-functional covariates. RESULTS: Unmet needs for daytime activities were associated with more affective symptoms at baseline, six and twelve months, mean 0.74 (p < 0.001), 0.76 (p < 0.001) and 0.78 (p = 0.001) points higher score respectively, and with more psychotic symptoms at baseline (mean 0.39 points, p = 0.007) and at six months follow-up (mean 0.31 points, p = 0.006). Unmet needs for company were associated with more affective symptoms at baseline, six and twelve months, mean 0.44 (p = 0.033), 0.67 (p < 0.001) and 0.91 (p < 0.001) points higher score respectively, and with more psychotic symptoms at baseline (mean 0.40 points, p = 0.005) and at six months (mean 0.35 points, p = 0.002) follow-up. CONCLUSION: Interventions to reduce unmet needs for daytime activities and company could reduce affective and psychotic symptoms in people with dementia.

A vulnerable journey towards professional empathy and moral courage.

Background: Empathy and moral courage are important virtues in nursing and nursing ethics. Hence, it is of great importance that nursing students and nurses develop their ability to empathize and their willingness to demonstrate moral courage. Research aim: The aim of this article is to explore third-year undergraduate nursing students' perceptions and experiences in developing empathy and moral courage. Research design: This study employed a longitudinal qualitative design based on individual interviews. Participants and research context: Seven undergraduate nursing students were interviewed during or immediately following their final clinical placement. Ethical considerations: The Norwegian Social Science Data Services (NSD) approved the study. Participants were informed that their participation was voluntary and were assured confidentiality. They were informed that they could withdraw from the study at any time, without providing reasons. Findings: Affective empathy seemed to be strong among third-year undergraduate nursing students. However, they tried to handle the situations in a 'professional' way, and to balance their emotions. At the same time, they expressed how difficult it can be to show moral courage when confronted with poor patient care. In addition, they spoke about a lack of role models during clinical practice and supervision. Conclusions: Undergraduate nursing students are in a vulnerable position throughout their journey to become professional and to develop empathy and moral courage. The professional socialisation and forming of professional empathy and moral courage among nursing students, may be seen as a complex interaction of formal and hidden curriculum, where role models play an important role. We argue that the main theme 'Vulnerable students - a journey towards professional empathy and moral courage' may cover the longitudinal project as a whole. This vulnerability is something both teachers and supervisors should be aware of when following up with students in their clinical placements.

Intake of whole grain and associations with lifestyle and demographics: a cross-sectional study based on the Danish Diet, Cancer and Health-Next Generations cohort.

PURPOSE: The aim was to analyze the intake of whole grain (WG) and associations with lifestyle and demographics in a newly established cohort of Danish adults. METHODS: Between 2015 and 2019, Danes were enrolled into The Diet, Cancer and Health-Next Generations cohort. A total of 38,553 persons were included in the current cross-sectional study, where all completed a 376-item food frequency questionnaire, a lifestyle questionnaire, and a physical examination in a study center where physical measurements and biological samples were collected. RESULTS: The median intake of WG was 79 g/10 mega joule (MJ) and 54% of the participants consumed the amount of WG recommended in Denmark, which is 75 g/10 MJ. The probability of consuming the recommended amount of WG was highest among men, persons < 30 years, students, persons with body mass index (BMI) < 25 kg/m2, persons participating in sports, who did not exceed the recommended maximum intake of alcohol and did not smoke. The probability of having a low intake of WG defined as < 25 g/10 MJ was highest among persons with short education, BMI ≥ 25 kg/m2, persons not participating in sports, persons having an alcohol intake above the recommended maximum level and persons being active smokers. CONCLUSION: The median intake of WG was 79 g/10 MJ. The probability of consuming at least 75 g WG/10 MJ was highest among persons who also adhered to healthy lifestyle measured by other factors. Only 6% of the cohort participants consumed < 25 g WG/10 MJ, these persons were more likely to have a general less healthy lifestyle.

Characteristics of patients assessed for cognitive decline in primary healthcare, compared to patients assessed in specialist healthcare.

Objective: The aim of this study was to describe patients assessed for cognitive decline in primary healthcare, compared to patients assessed in specialist healthcare and to examine factors associated with depression.Design: This was an observational study.Setting: Fourteen outpatient clinics and 33 general practitioners and municipality memory teams across Norway.Subjects: A total of 226 patients assessed in primary healthcare and 1595 patients assessed in specialist healthcare outpatient clinics.Main outcome measures: Cornell scale for depression in dementia (CSDD), Mini-Mental Status Examination (MMSE), Clock drawing test, Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Instrumental Activities of Daily Living, Personal Self-Maintenance Scale, Relatives' stress scale (RSS), and Neuropsychiatric Inventory Questionnaire (NPI-Q)Results: Patients assessed in primary healthcare were older (mean age 81.3 vs 73.0 years), less educated, had poorer cognition (MMSE median 22 vs 25), more limitations in activities of daily living (ADL), more behavioural and psychological symptoms of dementia (BPSD), more depressive symptoms (CSDD median 7 vs 5), more often lived alone (60% vs 41%) and were more often diagnosed with dementia (86% vs 47%) compared to patients diagnosed in specialist healthcare. Depression was associated with female gender, older age, more severe decline in cognitive functioning (IQCODE, OR 1.65), higher caregiver burden (RSS, OR 1.10) and with being assessed in primary healthcare (OR 1.53).Conclusion: Post-diagnostic support tailored to patients diagnosed with dementia in primary healthcare should consider their poor cognitive function and limitations in ADL and that these people often live alone, have BPSD and depression.Key pointsPeople diagnosed in Norwegian primary healthcare had more needs than people diagnosed in specialist healthcare. • They were older, less educated, had poorer cognitive functioning and activity limitations, more often lived alone, and had more BPSD and depression. • Depression was associated with being female, older, having cognitive decline, being assessed in primary care and the caregiver experiencing burden • Post diagnostic support for people with dementia should be tailored to the individual's symptoms and needs.

A four-stage process for intervention description and guide development of a practice-based intervention: refining the Namaste Care intervention implementation specification for people with advanced dementia prior to a feasibility cluster randomised trial.

BACKGROUND: Some interventions are developed from practice, and implemented before evidence of effect is determined, or the intervention is fully specified. An example is Namaste Care, a multi-component intervention for people with advanced dementia, delivered in care home, community, hospital and hospice settings. This paper describes the development of an intervention description, guide and training package to support implementation of Namaste Care within the context of a feasibility trial. This allows fidelity to be determined within the trial, and for intervention users to understand how similar their implementation is to that which was studied. METHODS: A four-stage approach: a) Collating existing intervention materials and drawing from programme theory developed from a realist review to draft an intervention description. b) Exploring readability, comprehensibility and utility with staff who had not experienced Namaste Care. c) Using modified nominal group techniques with those with Namaste Care experience to refine and prioritise the intervention implementation materials. d) Final refinement with a patient and public involvement panel. RESULTS: Eighteen nursing care home staff, one carer, one volunteer and five members of our public involvement panel were involved across the study steps. A 16-page A4 booklet was designed, with flow charts, graphics and colour coded information to ease navigation through the document. This was supplemented by infographics, and a training package. The guide describes the boundaries of the intervention and how to implement it, whilst retaining the flexible spirit of the Namaste Care intervention. CONCLUSIONS: There is little attention paid to how best to specify complex interventions that have already been organically implemented in practice. This four-stage process may have utility for context specific adaptation or description of existing, but untested, interventions. A robust, agreed, intervention and implementation description should enable a high-quality future trial. If an effect is determined, flexible practice implementation should be enabled through having a clear, evidence-based guide.

The Validity of the Norwegian Version of the Cognitive Function Instrument.

BACKGROUND/AIMS: A timely diagnosis of dementia is important, and the Cognitive Function Instrument (CFI) is a newly developed instrument to screen for cognitive decline. The aim of this study was to evaluate the validity and internal consistency of the Norwegian version of the CFI. METHODS: We included 265 participants with dementia, mild cognitive impairment (MCI), subjective cognitive impairment (SCI), and a reference group without subjective or assessed cognitive decline. The participants and their relatives answered the self- and proxy-rated versions of the CFI. RESULTS: The Norwegian CFI had power to discriminate between people with dementia and with MCI, SCI, and the reference group. The proxy version had better power than the self-rated version in our participants (area under the curve [AUC] proxy-rated varying from 0.79 to 0.99, AUC self-rated varying from 0.56 to 0.85). CONCLUSION: The Norwegian CFI was found to be a useful, valid, and robust instrument.

Experiences of attending day care services designed for people with dementia - a qualitative study with individual interviews.

OBJECTIVES: Day care is assumed to promote independence in home-dwelling people with dementia, increase well-being and enhance social stimulation. Few studies have directly engaged people with dementia to better understand the benefits and impacts of such services. The aim of this study was to explore attendees' experiences with day care designed for people with dementia. METHOD: This study had a qualitative descriptive design and included individual interviews with 17 users attending day care. The analysis was undertaken using content analyses. RESULTS: The participants reported that day care had a positive influence on their physical functioning, cognition, well-being, and situation at home because they were provided with social stimulation, meals, and activities. Day care contributed to the maintenance of a rhythm and structure in everyday life. Furthermore, the staff contributed to making the day care a safe place to be and enhanced a sense of belonging. CONCLUSION: This study reveals the positive impact of day care on the daily lives of people with dementia because this service contributes to the enhancement of activities and social support, prevents isolation, and enhances practical and cognitive functioning as experienced by the users. The staff has a major impact on the experience of the participants in the day care.

Undergraduate nursing students' ability to empathize: A qualitative study.

BACKGROUND: Empathy is of great importance in nursing, as it helps us to see and meet the needs of patients and hence to care for patients in an appropriate way. Therefore, it is of great importance that nursing students and nurses develop their ability to empathize. OBJECTIVE: The study aimed at gaining knowledge on what characterizes undergraduate nursing students' ability to empathize with patients during their first practice in a nursing home. In addition, the aim of the study was to investigate what nursing students think is important with regard to upholding their ability to empathize with patients in a professional way. RESEARCH DESIGN: This research has a phenomenological and hermeneutic design, based on qualitative interviews. Participants and research context: A total of 11 undergraduate nursing students participated in interviews during or right after their first practice in a nursing home. Ethical considerations: Norwegian Social Science Data Services approved the study. Participants were informed that their participation was voluntary. The participants were also assured confidentiality, and they were informed that they could withdraw from the study at any time, without providing any reasons. FINDINGS: What the findings show is that affective empathy is strong among undergraduate nursing students in their first practice. They think the emotions are important to be able to empathize, and they are afraid of becoming indifferent. At the same time, they are afraid that the feelings will hinder them from acting in a professional manner. DISCUSSION: The findings are discussed in light of previous theories on empathy, and especially perspectives on empathy, emotions, and morality. CONCLUSION: Affective empathy seems to be strong among nursing students, and this may be of great importance to be sensitive to patients' well-being. However, affective and cognitive empathy should be balanced if nurses will have to meet patients in a professional way.

International multi-site survey on the use of online support groups in bipolar disorder.

BACKGROUND: Peer support is an established component of recovery from bipolar disorder, and online support groups may offer opportunities to expand the use of peer support at the patient's convenience. Prior research in bipolar disorder has reported value from online support groups. AIMS: To understand the use of online support groups by patients with bipolar disorder as part of a larger project about information seeking. METHODS: The results are based on a one-time, paper-based anonymous survey about information seeking by patients with bipolar disorder, which was translated into 12 languages. The survey was completed between March 2014 and January 2016 and included questions on the use of online support groups. All patients were diagnosed by a psychiatrist. Analysis included descriptive statistics and general estimating equations to account for correlated data. RESULTS AND CONCLUSIONS: The survey was completed by 1222 patients in 17 countries. The patients used the Internet at a percentage similar to the general public. Of the Internet users who looked online for information about bipolar disorder, only 21.0% read or participated in support groups, chats, or forums for bipolar disorder (12.8% of the total sample). Given the benefits reported in prior research, clarification of the role of online support groups in bipolar disorder is needed. With only a minority of patients using online support groups, there are analytical challenges for future studies.

A multi-pronged investigation into the effect of glucose starvation and culture duration on fed-batch CHO cell culture.

In this study, omics-based analysis tools were used to explore the effect of glucose starvation and culture duration on monoclonal antibody (mAb) production in fed-batch CHO cell culture to gain better insight into how these parameters can be controlled to ensure optimal mAb productivity and quality. Titer and N-glycosylation of mAbs, as well as proteomic signature and metabolic status of the production cells in the culture were assessed. We found that the impact of glucose starvation on the titer and N-glycosylation of mAbs was dependent on the degree of starvation during early stationary phase of the fed-batch culture. Higher degree of glucose starvation reduced intracellular concentrations of UDP-GlcNAc and UDP-GalNAc, but increased the levels of UDP-Glc and UDP-Gal. Increased GlcNAc and Gal occupancy correlated well with increased degree of glucose starvation, which can be attributed to the interplay between the dilution effect associated with change in specific productivity of mAbs and the changed nucleotide sugar metabolism. Herein, we also show and discuss that increased cell culture duration negatively affect the maturation of glycans. In addition, comparative proteomics analysis of cells was conducted to observe differences in protein abundance between early growth and early stationary phases. Generally higher expression of proteins involved in regulating cellular metabolism, extracellular matrix, apoptosis, protein secretion and glycosylation was found in early stationary phase. These analyses offered a systematic view of the intrinsic properties of these cells and allowed us to explore the root causes correlating culture duration with variations in the productivity and glycosylation quality of monoclonal antibodies produced with CHO cells.

Balancing between dual belongings when organised into interdisciplinary teams, with the trust model as the context: A qualitative study.

BACKGROUND: Home-based healthcare services are facing challenges and pressures of increasing needs due to an ageing population, rising workload for an overburdened workforce, and limited financial resources. The trust model is an approach to address the challenges, by organizing the home-based healthcare services into smaller, autonomous interdisciplinary teams. The aim is to involve users and next of kin in decision-making and trusting frontline workers' professional judgement, thus making the services more flexible and individually tailored. This study explores frontline workers' practices and experiences of working within interdisciplinary teams according to the trust model's goals. METHODS: Observations, individual-, and focus groups interviews were conducted within home-based healthcare service in a Norwegian municipality. The participants were leaders and frontline workers at different levels of the home-based healthcare services, including registered nurses, auxiliary nurses, occupational therapists, physiotherapists, and other unskilled healthcare personnel. Data was analysed thematically. RESULTS: The results are presented in terms of themes: 'We all want the best for service users', 'Belonging to an interdisciplinary team' and 'Maintaining belonging to those with similar work tasks and responsibilities'. The results show a diversity among the participants' experiences of working within interdisciplinary teams. It demonstrates a dilemma between creating belonging to and forming identities within the interdisciplinary team, and at the same time, the importance of maintaining belonging and identity with those in the same profession or with the same tasks and responsibilities. CONCLUSION: This study suggests that the frontline workers need for dual belonging seems to be underestimated within the trust model, and by acknowledging this, organisations and policymakers can create environments that support both. Which in turn can enhance the possibility to deliver flexible and individually tailored services for service users.

Calories and portion sizes in recipes throughout 100 years: an overlooked factor in the development of overweight and obesity?

BACKGROUND: Large portion sizes have been associated with large energy intake, which can contribute to the development of overweight and obesity. Portion sizes of non-home cooked food have increased in the past 20 years, however, less is known about portion sizes of home-cooked food. AIM: The aim of the study was to assess if the portion sizes measured in calories in Danish cookbook recipes have changed throughout the past 100 years. METHODS: Portion size measured in calories was determined by content-analysis of 21 classic Danish recipes in 13 editions of the famous Danish cookbook "Food" from 1909 to 2009. Calorie content of the recipes was determined in standard nutritional software, and the changes in calories were examined by simple linear regression analyses. RESULTS: Mean portion size in calories increased significantly by 21% (ß = 0.63; p < 0.01) over the past 100 years in the analyzed recipes. The mean portion size in calories from a composed homemade meal increased by 77% (ß = 2.88; p < 0.01). The mean portion size in calories from meat increased by 27% (ß = 0.85; p = 0.03), starchy products increased by 148% (ß = 1.28; p < 0.01), vegetables increased by 37% (ß = 0.21; p = 0.13) and sauce increased by 47% (ß = 0.56; p = 0.02) throughout the years. CONCLUSIONS: Portion sizes measured in calories in classical Danish recipes have increased significantly in the past 100 years and can be an important factor in increased energy intake and the risk of developing overweight and obesity.

The power of observation. Occupational therapists' descriptions of doing observations of people with cognitive impairments in the context of community practice.

BACKGROUND: Observation is an important method for occupational therapists (OTs) to gather information on people's occupational performance; yet, not much research has been conducted on OTs' descriptions of doing observations in their practices. AIMS: This study aimed to explore community OTs descriptions of doing observations during the assessment of persons with cognitive impairments. MATERIAL AND METHODS: Nineteen OTs participated in focus group interviews. Thematic analysis with an inductive approach was performed. RESULTS: Three themes were revealed during analysis, the value of doing unstructured observations, the importance of doing observations in familiar contexts, and the importance of experience, structure and competence when doing observation. CONCLUSIONS AND SIGNIFICANCE: This study showed that the participants regarded observation as one of OTs' core competencies, and they described doing observations in different ways. The results emphasised the importance of doing unstructured observations in persons' familiar contexts when assessing persons with cognitive impairments. However, the participants highlighted the need for increasing OTs structure and competence through implementing more occupation-based standardised assessment tools for OTs in community services to facilitate evidence-based practice.

Perspectives on assistive technology among older Norwegian adults receiving community health services.

INTRODUCTION: The western world is seeking increased implementation of assistive technology (AT) to meet the challenges of an ageing population. The objective of this study is to explore perspectives on AT use among home-dwelling older adults with or without cognitive impairment. METHODS: This study combines findings from a cross-sectional study with a questionnaire package (n = 83) and from qualitative individual interviews (n = 7) and is part of a larger study, the Assisted Living Project. Combining methods promotes complementary inquiries into a phenomenon. RESULTS: The participants already use ATs: TVs, social alarms, mobile phones, stove timers, electronic medical dispensers, PCs and tablet computers. They were both optimistic and skeptical of AT, and expressed different perspectives and expressed different perspectives on ATs in relation to usability, privacy and fear of losing personal face-to-face care. CONCLUSIONS: This study reveals that older adults' perspectives on AT are multifaceted and complex, and can partly be explained by the interacting factors in the HAAT model: person, technology, environment, and context. Further exploration in relation to older adults with health challenges, as well as ethical perspectives on AT implementation, is required for this group. TRIAL REGISTRATION NUMBER: The Norwegian Research Council, Number 47996, funds the Assisted Living Project (ALP).IMPLICATIONS FOR REHABILITATIONThe study was useful in order to inform the health care services about older adults "perspectives on assistive technology".This study reveals the complexity of understanding perspectives towards and the use of assistive technology among older adults with or without cognitive impairment.This study contributes to the understanding of the interactions between the four components: humans, activities, technology and the context.

In vivo effect of rFVIII and rFVIIa in hemophilia A rats evaluated by the Tail Vein Transection Bleeding Model.

BACKGROUND: Preclinical bleeding models increase current hemophilia A (HA) knowledge and aid the development of new pharmacological treatments. There are several well-established mouse bleeding models, but limited options are available for rat models despite their high resemblance to human disease process. OBJECTIVE: To provide a comprehensive description of the tail vein transection (TVT) bleeding model in HA rats and examine the correlation between in vivo pharmacological efficacy and global hemostatic assays. METHODS: The TVT bleeding model was implemented in HA rats and used to perform dose-response studies with recombinant coagulation factors VIIa (rFVIIa) and VIII (rFVIII). After the TVT bleeding model, whole blood and plasma were collected from rats and evaluated with thrombin generation test (TGT) and rotational thromboelastometry (ROTEM). RESULTS: Using the TVT bleeding model, the potency of rFVIII and rFVIIa treatments in HA rats were assessed, and the pharmacological windows established for rFVIII (≤15 U/kg) and rFVIIa (≤2.7 mg/kg). ED50 was estimated to be 1.75 U/kg for rFVIII and 0.37 mg/kg for rFVIIa, whereas complete normalization was observed with 15 U/kg and 2.7 mg/kg respectively. Furthermore, responses to rFVIII and rFVIIa in the TGT and ROTEM assays strongly correlated to in vivo pharmacological efficacy. CONCLUSION: The TVT bleeding model in HA rats is a useful tool to assess the pharmacodynamic effects of hemostatic compounds in vivo, and strongly correlates to results obtained with TGT and ROTEM in HA rats, adding further value to the HA rat model in preclinical research.

Localization of the neuropeptides pituitary adenylate cyclase-activating polypeptide, vasoactive intestinal peptide, and their receptors in the basal brain blood vessels and trigeminal ganglion of the mouse CNS; an immunohistochemical study.

Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal peptide (VIP) are structurally related neuropeptides that are widely expressed in vertebrate tissues. The two neuropeptides are pleiotropic and have been associated with migraine pathology. Three PACAP and VIP receptors have been described: PAC1, VPAC1, and VPAC2. The localization of these receptors in relation to VIP and PACAP in migraine-relevant structures has not previously been shown in mice. In the present study, we used fluorescence immunohistochemistry, well-characterized antibodies, confocal microscopy, and three-dimensional reconstruction to visualize the distribution of PACAP, VIP, and their receptors in the basal blood vessels (circle of Willis), trigeminal ganglion, and brain stem spinal trigeminal nucleus (SP5) of the mouse CNS. We demonstrated a dense network of circularly oriented VIP fibers on the basal blood vessels. PACAP nerve fibers were fewer in numbers compared to VIP fibers and ran along the long axis of the blood vessels, colocalized with calcitonin gene-related peptide (CGRP). The nerve fibers expressing CGRP are believed to be sensorial, with neuronal somas localized in the trigeminal ganglion and PACAP was found in a subpopulation of these CGRP-neurons. Immunostaining of the receptors revealed that only the VPAC1 receptor was present in the basal blood vessels, localized on the surface cell membrane of vascular smooth muscle cells and innervated by VIP fibers. No staining was seen for the PAC1, VPAC1, or VPAC2 receptor in the trigeminal ganglion. However, distinct PAC1 immunoreactivity was found in neurons innervated by PACAP nerve terminals located in the spinal trigeminal nucleus. These findings indicate that the effect of VIP is mediated via the VPAC1 receptor in the basal arteries. The role of PACAP in cerebral arteries is less clear. The localization of PACAP in a subpopulation of CGRP-expressing neurons in the trigeminal ganglion points toward a primary sensory function although a dendritic release cannot be excluded which could stimulate the VPAC1 receptor or the PAC1 and VPAC2 receptors on immune cells in the meninges, initiating neurogenic inflammation relevant for migraine pathology.

Digital Assistive Technology to Support Everyday Living in Community-Dwelling Older Adults with Mild Cognitive Impairment and Dementia.

Objective: The objective of this review was to explore whether knowledge about and practice of technology for older adults with mild cognitive impairment (MCI) and dementia (D) had developed since our 2017 review. Furthermore, we wanted to explore the usability and acceptability of technology in the newer trials, and how these may impact quality of life, occupational performance and human dignity. Materials and Methods: We searched for primary studies published between 2017 and 2020 reusing medical subject heading (MeSH) terms in five databases - Medline, PsycINFO, Embase, Amed and Cinahl - and obtained 1452 titles. The titles were divided in six piles, two for each of the three authors. The titles were sorted utilizing the Rayyan web tool. Fourteen studies were included in this review. The Mixed Method Appraisal Tool (MMAT) was used to assess the quality of the studies examined. Results: This review included almost twice as many participants as in the 2007-2017 review. Since 2017, a shift seems to have occurred toward technologies that can be worn on the body to monitor body functions and report states, or imbalances. Moreover, research interest is now focused on mobile phone apps and wearables providing reminders and timely support, rather than on separate devices at home. Conclusion: The studies conducted since 2017 report on wearable and environmental digital assistive technologies and often with multiple purposes. Three strategies for support seem evident: prompting and reminding people with dementia, monitoring people with dementia at home using environmental sensors and biosensors and providing safety outdoors. Thus, there is still a need for further research on the impact of technologies promoting occupational performance, quality of life, and human dignity for independent living.
