- Purpose To investigate why nurse anesthetists and operating room nurses choose to stay in the same workplace.Design Qualitative design.Methods Individual interviews were conducted with 15 nurse specialists from four hospitals in Sweden. Two men and 13 women aged between 43 and 63 participated. Data were analyzed with systematic text condensation according to Malterud.Findings Three themes were identified. (1) Organizational stability contributed to low staff turnover, with good spirits between colleagues, representing everyone’s equal value and resulting in a feeling of homelikeness. (2) Sustained development in one’s own profession. (3) A humane head nurse who was at hand, who was a facilitator, who knew staff members, and eliminated obstacles for them.Conclusions In a nonhierarchical and stable organization with a head nurse with caritative leadership skills, a welcoming working environment with opportunities for professional development is created. Thus, nurse specialists choose to stay, contributing to organizational development.

- Abstract in UndeterminedInside a tunnel, electromagnetic wave propagation differs strongly from the well understood "open-air" situation. The characterization of the tunnel environment is crucial for deploying vehicular communication systems. In this paper we evaluate vehicle-to-vehicle (V2V) radio channel measurements inside a tunnel. We estimate the time-varying root mean square (rms) delay and Doppler spreads, as well as the excess delay and the maximum Doppler dispersion. The fading process in V2V communications is inherently non-stationary. Hence, we characterize the stationarity time, for which we can consider the fading process to be wide sense stationary. We show that the spreads, excess delay, and maximum Doppler dispersion are larger on average when both vehicles are inside the tunnel compared to the "open-air" situation. The temporal evolution of the stationarity time is highly influenced by the strength of time-varying multipath components and the distance between vehicles. Furthermore, we show the good fit of the rms delay and Doppler spreads to a lognormal distribution, as well as for the stationarity time. From our analysis we can conclude that the IEEE 802.11p standard will be robust towards inter-symbol and inter-carrier interference inside a tunnel.

- Residing with the exponential growth of gastronomy tourism research, a number of review articles have examined the relationship of gastronomy and tourism from distinct thematic and disciplinary perspectives. What remains absent is a comprehensive overview that encapsulates the interdisciplinary dimensions of this area of research. In response, this study comprehensively investigates gastronomy tourism literature utilizing a network and content analysis, with an aim to map the main subject areas concerned with gastronomy tourism and relations between varying subject areas. In doing so, themes determining gastronomy tourism and focus for future exploration are identified. The review findings suggest that the trajectory of gastronomy tourism research is characterized by the dominance of "tourism, leisure, and hospitality management" and "geography, planning, and development." Three recommendations are proposed to assist development of gastronomy tourism research: increased dialogue across subject areas, development of critical and theoretical approaches, and greater engagement with sustainability debates.

- Raman and Fourier transform IR (FTIR) microspectroscopic images of biological material (tissue sections) contain detailed information about their chemical composition. The challenge lies in identifying changes in chemical composition, as well as locating and assigning these changes to different conditions (pathology, anatomy, environmental or genetic factors). Multivariate data analysis techniques are ideal for decrypting such information from the data. This protocol provides a user-friendly pipeline and graphical user interface (GUI) for data pre-processing and unmixing of pixel spectra into their contributing pure components by multivariate curve resolution-alternating least squares (MCR-ALS) analysis. The analysis considers the full spectral profile in order to identify the chemical compounds and to visualize their distribution across the sample to categorize chemically distinct areas. Results are rapidly achieved (usually <30-60 min per image), and they are easy to interpret and evaluate both in terms of chemistry and biology, making the method generally more powerful than principal component analysis (PCA) or heat maps of single-band intensities. In addition, chemical and biological evaluation of the results by means of reference matching and segmentation maps (based on k-means clustering) is possible.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Self-care is an important patient-reported outcome (PRO) for heart failure (HF) patients, which might be affected by disease management and/or telemonitoring (TM). The number of studies reporting the influence of TM on self-care is limited. Aims: This study aimed: to assess whether TM, in addition to information-and-communication-technology (ICT)-guided disease management system (ICT-guided DMS), affects self-care behavior; to evaluate the dynamics of self-care during the study; to investigate factors contributing to self-care changes; and to identify a patient profile that predisposes the patient to improvement in self-care. Methods: In the INnovative ICT-guided-DMS combined with Telemonitoring in OUtpatient clinics for Chronic HF patients (IN TOUCH) study, 177 patients were randomized to either ICT-guided DMS or TM+ICT-guided DMS, with a follow-up of 9 months. The current analysis included 118 participants (mean age: 69 +/- 11.5 years; 70% male) who filled the following PRO instruments: the nine-item European Heart Failure Self-care Behaviour scale (EHFScBs), Hospital Anxiety and Depression scale (HADs), and Minnesota Living with HF Questionnaire (MLHFQ). Results: The baseline level of self-care was better in the TM+ICT-guided-DMS group (n=58) compared to ICT-guided-DMS group (n=60, p=0.023). Self-care behavior improved in the ICT-guided-DMS group (p amp;lt; 0.01) but not in the TM+ICT-guided-DMS group. Factors associated with self-care worsening were as follows: higher physical subscale of MLHFQ (per 10 points, p amp;lt; 0.05), lower left ventricular ejection fraction (LVEF) (per 5%, p amp;lt; 0.05), lower New York Heart Association (NYHA) class (class III vs class II, p amp;lt; 0.05). The subgroups of patients who had an initial EHFScBs total score amp;gt; 28, or from 17 to 28 with concomitant HADs depression subscale (HADs_D) score amp;lt;= 8, demonstrated the greatest potential to improve self-care during the study. Conclusion: TM did not have an advantage on self-care improvement. Poor physical aspect of quality of life. lower LVEF, and lower NYHA class were associated with self-care worsening. The greatest self-care improvement may be achieved in those patients who have low or medium initial self-care level in the absence of depression.

- The lack of specialist nurses in operating theatres is a serious problem. The aim of this study was to describe reasons why specialist nurses in perioperative care chose to leave their workplaces and to describe the process from the thought to the decision. Twenty specialist nurses (i.e. anaesthesia, NA, and operating room nurses) from seven university- and county hospitals in Sweden participated in qualitative individual in-depth interviews. Data were analysed by systematic text condensation. We identified four themes of reasons why specialist nurses quitted their jobs: the head nurses' betrayal and dismissive attitude, and not feeling needed; inhumane working conditions leading to the negative health effects; not being free to decide about one's life and family life being more important than work; and, colleagues' diminishing behaviour. Leaving one's job was described as a process and specialist nurses had thought about it for some time. Two main reasons were described; the head nurse manager's dismissive attitude and treatment of their employees and colleagues' mistreatment and colleagues' diminishing behaviour. Increasing knowledge on the role of the head nurse managers in specialist nurses' decision making for leaving their workplace, and creating a friendly, non-violent workplace, may give the opportunity for them to take action before it is too late.

- BACKGROUND: Shortage of health-care workers e.g. in operating theatres is a global problem. A shortage of staff negatively affects patient outcomes, making it important to keep the employees from quitting. The aim of this survey was to study if well-being, zest for work, and thoughts about leaving work in an operating theatre can be related to the psychosocial work environment, as described by the job demand-control-support (JDCS) model.METHODS: A questionnaire was provided to personnel in operating theatres of seven Swedish hospitals (n = 1405, with a response rate of 68%) that included the JDCS model, personal factors, work ability, well-being, zest for work, and thoughts about leaving their position. Ordinal scale regression was used for analyses.RESULTS: A majority reported moderate to high zest for work (76%). A minority (30%) had sometimes thought during at least one month in the last year of leaving their position. Lower social support scores and high demands together with low control (high-strain) scores were related to lower well-being, lower zest for work, and more thoughts about leaving the position. Anaesthetists scored in the low-strain field, nurse anaesthetists and assistant nurses in the passive field, and operating nurses in the active field, in comparison to all personnel.CONCLUSION: According to the JDCS model, both lower social support and high strain were related to lower well-being and negative thoughts about the position. Social support scores were about the same for different occupational groups in the operating theatre, and no occupation scored on average in the high-strain field.

A subset of type-II collagen-binding antibodies prevents experimental arthritis by inhibiting FCGR3 signaling in neutrophils

Tidskriftsartikel (refereegranskat)abstract
- Rheumatoid arthritis (RA) involves several classes of pathogenic autoantibodies, some of which react with type-II collagen (COL2) in articular cartilage. We previously described a subset of COL2 antibodies targeting the F4 epitope (ERGLKGHRGFT) that could be regulatory. Here, using phage display, we developed recombinant antibodies against this epitope and examined the underlying mechanism of action. One of these antibodies, R69-4, protected against cartilage antibody- and collagen-induced arthritis in mice, but not autoimmune disease models independent of arthritogenic autoantibodies. R69-4 was further shown to cross-react with a large range of proteins within the inflamed synovial fluid, such as the complement protein C1q. Complexed R69-4 inhibited neutrophil FCGR3 signaling, thereby impairing downstream IL-1β secretion and neutrophil self-orchestrated recruitment. Likewise, human isotypes of R69-4 protected against arthritis with comparable efficiency. We conclude that R69-4 abrogates autoantibody-mediated arthritis mainly by hindering FCGR3 signaling, highlighting its potential clinical utility in acute RA.
