    Objectives: Genetic variations in TNFAIP3 (A20) de-ubiquitinase (DUB) domain increase the risk of systemic lupus erythematosus (SLE) and rheumatoid arthritis. A20 is a negative regulator of NF-κB but the role of its DUB domain and related genetic variants remain unclear. We aimed to study the functional effects of A20 DUB-domain alterations in immune cells and understand its link to SLE pathogenesis. Methods: CRISPR/Cas9 was used to generate human U937 monocytes with A20 DUB-inactivating C103A knock-in (KI) mutation. Whole genome RNA-sequencing was used to identify differentially expressed genes between WT and C103A KI cells. Functional studies were performed in A20 C103A U937 cells and in immune cells from A20 C103A mice and genotyped healthy individuals with A20 DUB polymorphism rs2230926. Neutrophil extracellular trap (NET) formation was addressed ex vivo in neutrophils from A20 C103A mice and SLE-patients with rs2230926. Results: Genetic disruption of A20 DUB domain in human and murine myeloid cells did not give rise to enhanced NF-κB signalling. Instead, cells with C103A mutation or rs2230926 polymorphism presented an upregulated expression of PADI4, an enzyme regulating protein citrullination and NET formation, two key mechanisms in autoimmune pathology. A20 C103A cells exhibited enhanced protein citrullination and extracellular trap formation, which could be suppressed by selective PAD4 inhibition. Moreover, SLE-patients with rs2230926 showed increased NETs and increased frequency of autoantibodies to citrullinated epitopes. Conclusions: We propose that genetic alterations disrupting the A20 DUB domain mediate increased susceptibility to SLE through the upregulation of PADI4 with resultant protein citrullination and extracellular trap formation

    A good death from the perspective of patients with severe illness and advance care planning (ACP) in patients near end-of-life

    Previous research has indicated that what constitutes a good death is heterogenic and complex although there are some recurrent themes and similarities regardless individual background factors. Studies on advance care planning (ACP), i.e. making proactive plans regarding content of care and treatment limitations, on nursing home (NH) patients are rare. Positive effects of ACPs are shown, but also that these often are lacking. The overall aim with this thesis was to explore the perceptions of a good death from the perspective of patients with severe illness and to investigate, from different perspectives, experiences of ACP in a NH context.  In paper I, patients with cancer in a palliative phase were interviewed on their perceptions of a good death. Death was viewed as a process and previous experiences on the death of others influenced their own perceptions. A good death was associated with living with the prospect of imminent death, preparing oneself and others for one’s death and dying comfortably, e.g. without suffering, with independence and with social relations intact. Some were comforted by their belief that death is predetermined, and that after death, there is something else. Others felt uncomfortable when they viewed death as the end of the existence.  In paper II, nurses and physicians were interviewed on their experiences of the factors that shape the ACP process in NHs. Exploration of the patient’s preferences regarding content of care and treatment limitations was important, as well as integration of the patient’s preferences and the views of the family members and staff concerning these questions. ACP documentation had to be clear, updated and available for staff and the implementation and reevaluation of ACP were also considered important, according to the participants. Significance of clinicians’ perceiving beneficence as well as fear of accusations of maleficence were shown to be essential factors to contemplate.  In a retrospective chart review (paper III), medical records of 367 deceased NH patients were analysed. A high prevalence of ACP was shown, using two different definitions of ACP (ACP I and ACP II). Moreover, adherence to the ACP content was strong and positive associations were seen between ACP and variables of the three research aims, such as: diagnosis (dementia), physician attendance at NH and end-of-life (EOL) care.  In paper IV, family members of deceased NH patients were interviewed on their experiences of ACP in NHs. EOL issues were challenging to talk about, although the family members appreciated staff raising these questions. The patient’s preferences were sometimes explicitly or implicitly communicated. However, in some cases, family members had a feeling of the patient’s preferences, although they had not been clearly communicated. Everyday details symbolised staff commitment. The family members viewed the nurse as central. The physician was described as absent and ACP meetings often went unnoticed. Both involvement and lack of involvement could cause the family members feelings of guilt.  In conclusion, we found that what constitutes a good death is highly individual, although recurrent themes are seen. EOL conversations are important and challenging and need staff training and experience. It seems important to support healthcare staff not only to initiate ACP in NH patients, but also to involve the patient and family members in the ACP and planning EOL care. Making proactive plans regarding content of care including treatment limitations, could enable patient autonomy, optimise the chances for the patient to experience a good death and enhance for the family members during the dying trajectory and after the patient’s death.

    Objective: To investigate clinicians perspectives on the factors that shape the process of advance care planning in a nursing home context. Design: Interviews. Latent qualitative content analysis. Setting: Nine nursing homes in Sweden. Subjects: 14 physicians and 11 nurses working at nursing homes. Main outcome measures: Participants views on advance care planning (ACP) at nursing homes. Results: The analysis of the interviews resulted in four manifest categories: Exploration of preferences and views, e.g. exploring patient wishes regarding end-of-life issues and restrictions in care at an early stage, and sensitivity to patients readiness to discuss end-of-life issues; Integration of preferences and views, e.g. integration of patients preferences and staffs and family members views; Decision amp; documentation of the ACP, e.g. clear documentation in patients medical records that are up-to-date and available for staff caring for the patient, and Implementation amp; re-evaluation of the ACP, e.g. nurse following up after ACP-appointment to confirm the content of the documented ACP. The latent theme, Establishing beneficence - defending oneself against tacit accusations of maleficence, emerged as a deeper meaning of all the four (manifest) parts of the ACP-process Conclusion: This study stresses the importance of involving patients, family members, and the team in the work with advance care planning in nursing homes. In addition, clear medical record documentation and proficiency in end-of-life communication related to advance care planning for physicians as well as nurses may also be factors that significantly shape advance care planning in a nursing home context

    Objective To explore family members experiences of advance care planning in nursing homes. Design Individual interviews. Thematic analysis. Setting Four nursing homes in Sweden. Subjects Eighteen family members of deceased nursing home patients. Main outcome measures Family members experiences of advance care planning in nursing homes. Results Family members experiences of advance care planning in a nursing home context involved five themes: Elephant in the room, comprising end-of-life issues being difficult to talk about; Also silent understanding, e.g. patients preferences explicitly communicated, but also implicitly conveyed. In some cases family members had a sense of the patients wishes although preferences had not been communicated openly; Significance of small details, e.g. family members perceive everyday details as symbols of staff commitment; Invisible physician, supporting nurse, e.g. nurse being a gatekeeper, providing a first line assessment in the physicians absence; and Feeling of guilt, e.g. family members wish to participate in decisions regarding direction of care and treatment limits, and need guidance in the decisions. Conclusion Our study stresses the significance of staff involving the patient and family members in the advance care planning process in nursing homes, thereby adapting the care in line with patients wishes, and for the patient to share these preferences with family members. Education in communication related to the subject may be important to shape advance care planning

    Association between vaccination and preventive routines on COVID-19-related mortality in nursing home facilities : a population-based systematic retrospective chart review

    Background:Older and frail individuals are at high risk of dying from COVID-19, and residents in nursing homes (NHs) are overrepresented in death rates. We explored four different periods during the COVID-19 pandemic to analyze the effects of improved preventive routines and vaccinations, respectively, on mortality in NHs. Methods:We undertook a population-based systematic retrospective chart review comprising 136 NH facilities in southeast Sweden. All residents, among these facilities, who died within 30 days after a laboratory-verified COVID-19 diagnosis during four separate 92-day periods representing early pandemic (second quarter 2020), middle of the pandemic (fourth quarter 2020), early post-vaccination phase (first quarter 2021), and the following post-vaccination phase (second quarter 2021). Mortality together with electronic chart data on demographic variables, comorbidity, frailty, and cause of death was collected. Results:The number of deaths during the four periods was 104, 120, 34 and 4, respectively, with a significant reduction in the two post-vaccination periods (P < 0.001). COVID-19 was assessed as the dominant cause of death in 20 (19%), 19 (16%), 4 (12%) and 1 (3%) residents in each period (P < 0.01). The respective median age in the four studied periods varied between 87and 89 years, and three or more diagnoses besides COVID-19 were present in 70-90% of the respective periods study population. Considerable or severe frailty was found in all residents. Conclusions:Vaccination against COVID-19 seems associated with a reduced number of deaths in NHs. We could not demonstrate an effect on mortality merely from the protective routines that were undertaken

    Objective Studies on advance care planning in nursing homes are rare, and despite their demonstrated favourable effects on end-of-life care, advance care plans are often lacking. Therefore, we wished to explore: (i) the prevalence of advance care plans in a Swedish nursing home setting using two different definitions, (ii) the content of advance care plans, (iii) adherence to the content of care plans and (iv) possible associations between the presence of advance care planning and background characteristics, physician attendance and end-of-life care. Design Retrospective chart review. Setting Twenty-two nursing homes in Sweden. Subjects A total of 367 deceased patients (included between 1 June 2018 and 23 May 2020) who had lived in nursing homes. Main outcome measures Electronic health record data on the prevalence of advance care plans with two different definitions and variables regarding background characteristics, physician attendance and end-of-life care, were collected. Results Of the study population, 97% had a limited care plan (ACP I) documented. When using the comprehensive definition (ACP II), also including patients preferences and involvement of family members in advance care planning, the prevalence was 77%. Patients with dementia more often had care plans, and a higher physician attendance was associated with presence of advance care plans. Prescription of palliative drugs and information to family members of the patients deterioration and impending death were more common in patients with care plans compared to those where such plans were missing. There was adherence to the care plan content. Conclusion In contrast to previous research, this study showed a high prevalence of advance care plans in nursing home patients. Patients with care plans more frequently received prescriptions of palliative drugs and their family members were informed to a greater extent about the patients deterioration and impending death compared to those without care plans. These aspects are often seen as vital components of good palliative care.Funding Agencies|Medical Research Council of Southeast SwedenUK Research &amp; Innovation (UKRI)Medical Research Council UK (MRC) [FORSS-930962, FORSS-940756]; County Council of Ostergotland [RO-938269]</p

    Trustful conversations: a qualitative interview study on older patients experiences of the intervention Proactive healthcare in a Swedish primary care setting

    No full text
    Aim: To explore older patients experiences of the intervention Proactive healthcare for frail elderly persons. Background: Previous research has indicated that continuity and good access to primary care can improve satisfaction in older people seeking care. However, little is known about the older patients experiences in taking part of interventions aiming to enhance the care. Methods: Individual interviews were conducted with 24 older patients who participated in the intervention Proactive healthcare for frail elderly persons, selected from nine Swedish primary care centres. Interviews were analysed using qualitative content analysis. Findings: Older patients experiences of the intervention involved five manifest categories: Ways of naming the elder care team, covering the older patients lack of understanding regarding their connection to the team, and the need for clarity on this and on how the specialised care provided differed from conventional care; Availability, indicating how older patients associated easy access and a direct telephone number with a team nurse available at certain times with a sense of security; The importance of relations, covering how patients appreciated continuity in their personal and professional conversations with staff; A feeling of safety and trust, stressing the value of older persons attach to being given enough time, to be listened to and being recognised as people; and Finiteness of life, which refers to the difficulty of having end-of-life conversations and the need for experienced staff with personal knowledge of the patients. The latent theme Trustful conversations was created to give a deeper meaning to the content of the categories.Trustful conversations, created through good personal knowledge of patients and continuity of contact, engender a feeling of safety in older patients. Using elder care teams could result in a better quality of care, with increased satisfaction and feelings of security among patients, and a reduction in healthcare needs

    A Comprehensive Evaluation of the Relationship Between Different IgG and IgA Anti-Modified Protein Autoantibodies in Rheumatoid Arthritis

    Seropositive rheumatoid arthritis (RA) is characterized by the presence of rheumatoid factor (RF) and anti-citrullinated protein autoantibodies (ACPA) with different fine-specificities. Yet, other serum anti-modified protein autoantibodies (AMPA), e.g. anti-carbamylated (Carb), -acetylated (KAc), and malondialdehyde acetaldehyde (MAA) modified protein antibodies, have been described. In this comprehensive study, we analyze 30 different IgG and IgA AMPA reactivities to Cit, Carb, KAc, and MAA antigens detected by ELISA and autoantigen arrays in N=1985 newly diagnosed RA patients. Association with patient characteristics such as smoking and disease activity were explored. Carb and KAc reactivities by different assays were primarily seen in patients also positive for anti-citrulline reactivity. Modified vimentin (mod-Vim) peptides were used for direct comparison of different AMPA reactivities, revealing that IgA AMPA recognizing mod-Vim was mainly detected in subsets of patients with high IgG anti-Cit-Vim levels and a history of smoking. IgG reactivity to acetylation was mainly detected in a subset of patients with Cit and Carb reactivity. Anti-acetylated histone reactivity was RA-specific and associated with high anti-CCP2 IgG levels, multiple ACPA fine-specificities, and smoking status. This reactivity was also found to be present in CCP2+ RA-risk individuals without arthritis. Our data further demonstrate that IgG autoreactivity to MAA was increased in RA compared to controls with highest levels in CCP2+ RA, but was not RA-specific, and showed low correlation with other AMPA. Anti-MAA was instead associated with disease activity and was not significantly increased in CCP2+ individuals at risk of RA. Notably, RA patients could be subdivided into four different subsets based on their AMPA IgG and IgA reactivity profiles. Our serology results were complemented by screening of monoclonal antibodies derived from single B cells from RA patients for the same antigens as the RA cohort. Certain CCP2+ clones had Carb or Carb+KAc+ multireactivity, while such reactivities were not found in CCP2- clones. We conclude that autoantibodies exhibiting different patterns of ACPA fine-specificities as well as Carb and KAc reactivity are present in RA and may be derived from multireactive B-cell clones. Carb and KAc could be considered reactivities within the "Cit-umbrella" similar to ACPA fine-specificities, while MAA reactivity is distinctly different
