Tidskriftsartikel (refereegranskat)abstract
- Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Despite the increasing longevity of the world's population, with an unprecedented rise in the number of people who need palliative care (PC), there has been sparse research regarding palliative care for older people, especially when it comes to comparison of PC between healthcare systems and cultures. The aim of this systematic scoping review was to identify the characteristics of the body of literature and to examine the knowledge gaps concerning PC research for older people (> 60 years) in two healthcare systems and cultures, mainland China and Sweden.METHODS: The guidelines PRISMA (Preferred Reporting Items for Systematic Reviews), and PICOS (Patient/population, Intervention, Comparison/control, and Outcome) were used. Empirical studies on patients 60 years or older, next of kin or staff participating in a palliative care intervention or setting were included. They were conducted in mainland China or in Sweden during 2007-2019, were published in English and were extracted from seven databases: Embase, PubMed, Scopus, Cinahl, PsycInfo, Academic Search Complete and Cochrane Library. Two independent researchers conducted the selection of studies, data extraction and methodological evaluation. Any disagreements were resolved in consultation with a third researcher. The analysis was manifest directed content analysis based on PICOS domains.RESULTS: Of the 15 studies, four were from mainland China and 11 from Sweden. Both countries included older patients with cancer but also other end-stage diseases such as heart failure and dementia. The studies differed in design, method and the content of the interventions. The study in China based on traditional Chinese medicine concerns traditional Chinese folk music. The six qualitative studies from Sweden were evaluations of five interventions.CONCLUSIONS: Despite the high age of the participating patients, there was no focus on an ageing perspective concerning palliative care. To adapt to the changes taking place in most societies, future research should have increased focus on older persons' need for palliative care and should take account of issues concerning research ethics, ethnicity and culture.REGISTERED IN PROSPERO: CRD42020078685 , available from.

Ny definition av palliativ vård med fokus på lidande
- 2020

Ingår i: Lakartidningen. - 0023-7205 .- 1652-7518. ; 117

Tidskriftsartikel (refereegranskat)abstract
- Palliative care was initially developed for patients with a cancer diagnosis and severe symptoms. Despite the ambition to broaden the palliative care approach to include other groups, patients with cancer are still a majority in specialised palliative care. The broader view and development of palliative care has led to an intense debate on existing definitions. Following a request from The Lancet Commission on global palliative care, the International Association of Hospice and Palliative Care (IAHPC) has presented a new definition. The proposal was developed in several stages, in collaboration with specialists in palliative care from a total of 88 countries. The IAHPC's definition differs from the WHO's definition in several aspects. Most importantly, the IAHPC's definition takes a reversed perspective and instead of focusing on life-threatening illness as motivating palliative care, the new proposal focuses on serious suffering of a person with severe illness.

Nurses' experiences of using the Integrated Palliative care Outcome Scale with patients in specialized palliative care : A qualitative focus group study
- 2023

- AIM : To explore nurses' experiences of using the Integrated Palliative care Outcome Scale (IPOS) as a communication tool in specialized palliative care. DESIGN : This study employed a qualitative inductive approach. The Standards for Reporting Qualitative Research were followed for reporting. METHODS : Five focus groups were conducted with nurses from four specialized palliative care units, and the discussions were analysed with quality content analysis. RESULTS : Using IPOS for communication with the patient gave an opportunity to understand the patient's care needs and to let these care needs guide care interventions. Prerequisites in terms of relation, atmosphere, skills and flexibility were needed to establish an interactive communication. It was challenging to communicate about issues that evoked emotional reactions in the patient. There was a balancing act between the use of a structured scale and overcoming communication challenges. Nonetheless, when the two complemented each other, IPOS was a useful tool for nurses to promote person-centred care.

Sensations, symptoms, and then what? : Early bodily experiences prior to diagnosis of lung cancer
- 2021
-
Ingår i: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 16:3

Tidskriftsartikel (refereegranskat)abstract
- Lung cancer (LC) generally lacks unique core symptoms or signs. However, there are a multitude of bodily sensations that are often non-specific, not easily understood, and many times initially not recognized as indicative of LC by the affected person, which often leads to late diagnosis. In this international qualitative study, we inductively analyzed retrospective accounts of 61 people diagnosed with LC in Denmark, England and Sweden. Using the bodily sensations they most commonly spoke about (tiredness, breathlessness, pain, and cough), we constructed four sensation-based cases to understand the pre-diagnostic processes of reasoning and practice triggered by these key indicators of LC. We thereafter critically applied Hay's model of sensations to symptoms transformation, examining its central concepts of duration, disability and vulnerability, to support understanding of these processes. We found that while duration and disability are clearly relevant, vulnerability is more implicitly expressed in relation to perceived threat. Tiredness, even when of long duration and causing disability, was often related to normal aging, rather than a health threat. Regardless of duration, breathlessness was disturbing and threatening enough to lead to care-seeking. Pain varied by location, duration and degree of disability, and thus also varied in degree of threat perceived. Preconceived, but unmet expectations of what LC-related cough and pain would entail could cause delays by misleading participants; if cough lasted long enough, it could trigger health care contact. Duration, disability, and sense of threat, rather than vulnerability, were found to be relevant concepts for understanding the trajectory to diagnosis for LC among these participants. The process by which an individual, their family and health care providers legitimize sensations, allowing them to be seen as potential symptoms of disease, is also an essential, but varying part of the diagnostic processes described here.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundEven when palliative care is an integrated part of the healthcare system, the quality is still substandard for many patients and often initiated too late. There is a lack of structured guidelines for identifying and caring for patients; in particular for those with early palliative care needs. A care guide can act as a compass for best practice and support the care of patients throughout their palliative trajectory. Such a guide should both meet the needs of health care professionals and patients and families, facilitating discussion around end-of-life decision-making and enabling them to plan for the remaining time in life. The aim of this article is to describe the development and pilot testing of a novel Swedish palliative care guide.MethodsThe Swedish Palliative Care Guide (S-PCG) was developed according to the Medical Research Council framework and based on national and international guidelines for good palliative care. An interdisciplinary national advisory committee of over 90 health care professionals together with patient, family and public representatives were engaged in the process. The feasibility was tested in three pilot studies in different care settings.ResultsAfter extensive multi-unit and interprofessional testing and evaluation, the S-PCG contains three parts that can be used independently to identify, assess, address, follow up, and document the individual symptoms and care-needs throughout the whole palliative care trajectory. The S-PCG can provide a comprehensive overview and shared understanding of the patients’ needs and possibilities for ensuring optimal quality of life, the family included.ConclusionsBased on broad professional cooperation, patients and family participation and clinical testing, the S-PCG provides unique interprofessional guidance for assessment and holistic care of patients with palliative care needs, promotes support to the family, and when properly used supports high-quality personalised palliative care throughout the palliative trajectory. Future steps for the S-PCG, entails scientific evaluation of the clinical impact and effect of S-PCG in different care settings – including implementation, patient and family outcomes, and experiences of patient, family and personnel.

- Purpose: Getting an incurable oesophageal or gastric cancer diagnosis is a major stressful life event associated with severe physical, psychosocial and existential challenges. To provide timely and efficient support, based on patients' experiences, the aim of the study was to explore how patients newly diagnosed with incurable oesophageal and gastric cancer manage everyday life. Method: Semi-structured interviews were conducted with 12 patients 1–3 months after being diagnosed with incurable oesophageal or gastric cancer. Four participants were interviewed twice, which resulted in 16 interviews. Data were analysed with qualitative content analysis. Results: An overall theme, “Striving towards normality in an unpredictable situation”, with three related themes – “Trying to comprehend the disease”, “Dealing with the consequences of illness” and “Re-evaluating what is important in everyday life” – and seven sub-themes were identified. The participants described an unexpected and unpredictable situation, in which they strived to maintain their normal life. Amidst struggling to manage problems related to eating, fatigue and an incurable diagnosis the participants talked about the importance of focusing on the positive and normal aspects of life. Conclusions: The findings in this study point to the importance of supporting patients’ confidence and skills, particularly with regard to managing eating, so that they can hold on to their normal life as much as possible. The findings further point to the possible benefit of integrating an early palliative care approach and could provide guidance for nurses and other professionals on how to support patients post diagnosis.

Symptoms, problems and quality of life in patients newly diagnosed with oesophageal and gastric cancer - a comparative study of treatment strategy
- 2022
-
Ingår i: BMC Cancer. - : Springer Science and Business Media LLC. - 1471-2407. ; 22, s. 1-14

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with oesophageal and gastric cancer have a low likelihood of being cured and suffer from a broad spectrum of symptoms and problems that negatively affect their quality-of-life (QOL). Although the majority (67-75%) of patients at the time of diagnosis suffer from an incurable disease, research has primarily focused on the pre- and postoperative phase among patients treated with curative intent, with little attention to symptoms and problems in the diagnostic phase, especially in those who cannot be offered a cure.METHODS: In this cross-sectional study 158 patients newly diagnosed with oesophageal and gastric cancer visiting the surgical outpatient department for a preplanned care visit were included consecutively during 2018-2020. The validated instruments QLQ-C30 and QLQ-OG25, developed by the European Organization for Research and Treatment of Cancer (EORTC), and selected items from the Integrated Patient Outcome Scale (IPOS) were used to assess QOL, symptoms and problems. Differences between patients with a curative and a palliative treatment strategy were analysed using t-test and Mann-Whitney U test. The QLQ-C30 and QLQ-OG25 scores were compared to published reference data on the general Swedish population.RESULTS: Among all, the QOL was markedly lower, compared with general Swedish population (mean ± SD, 55.9 ± 24.7 vs 76.4 ± 22.8, p < 0.001). Compared to general population, the patients had significant impairment in all QOL aspects, particularly for role and emotional functioning and for symptoms such as eating-related problems, fatigue, insomnia and dyspnea. Majority of patients also reported severe anxiety among family and friends. Among patients with oesophageal cancer those with a palliative treatment strategy, compared with curative strategy, reported significantly lower QOL (mean ± SD, 50.8 ± 28.6 vs 62.0 ± 22.9 p = 0.030), physical (65.5 ± 22.6 vs 83.9 ± 16.5, p < 0.001) and role functioning (55.7 ± 36.6 vs 73.9 ± 33.3, p = 0.012), and a higher burden of several symptoms and problems. No significant differences between treatment groups were shown among patients with gastric cancer.CONCLUSIONS: Patients newly diagnosed with oesophageal and gastric cancer, and especially those with incurable oesophageal cancer, have a severely affected QOL and several burdensome symptoms and problems. To better address patients' needs, it seems important to integrate a palliative approach into oesophageal and gastric cancer care.
