- AimsTo describe assistant nurses' experiences of thirst and ethical challenges in relation to thirst in terminally ill patients in specialized palliative care (PC) units.DesignA qualitative, reflexive thematic design with an inductive analysis was used.MethodsData were collected during November 2021-January 2023. Twelve qualitative interviews with assistant nurses working in five different specialized PC units in different hospitals in Sweden were conducted. The interviews were transcribed verbatim and analysed with a reflexive thematic analysis. The study was guided by the Standards for Reporting Qualitative Research (SRQR).ResultsTwo main themes were found in this study. (1) 'A world of practice for thirst relief' where assistant nurses present a task-oriented world where the knowledge of thirst is an experience-based unspoken knowledge where mainly routines rule. (2) Ethical challenges presents different ethical problems that they meet in their practice, such as when patients express thirst towards the end of their life but are too severely ill to drink or when they watch lack of knowledge in the area among other health professionals.ConclusionThirst in dying patients is a neglected area that assistant nurses work with, without communicating it. Their knowledge of thirst and thirst relief are not expressed, seldom discussed, there are no policy documents nor is thirst documented in the patient's record. There is a need for nurses to take the lead in changing nursing practice regarding thirst.Patient or Public ContributionNo patient or public contribution.ImpactIn palliative care, previous studies have shown that dying patients might be thirsty. Assistant nurses recognize thirst in dying patients, but thirst is not discussed in the team. Nurses must consider the patient's fundamental care needs and address thirst, for example in the nursing process to ensure patients quality of life in the last days of life.Reporting MethodThe study was guided by the SRQR.What does this Article Contribute to the Wider Global Clinical Community?Thirst is a distressing symptom for all humans. However, when a patient is dying, he or she loses several functions and can no longer drink independently. The knowledge from this article contributes to our understanding of current practice and shows an area that requires immediate attention for the improvement of fundamental palliative care delivery.

- BACKGROUND:The current study investigates circulating eosinophils and neutrophils in Alzheimer's (AD) type dementia with respect to density (kg/L). The existence of β-amyloid plaques in the brain is a feature of AD. Sporadic scientific reports indicate that the disease affects circulating neutrophils. In contrast, numerous publications investigate inflammatory reactions in AD brains. Locally, the plaques evoke a substantial inflammatory response involving activated microglia and astrocytes.METHODS:Subjects with probable AD (n = 39) were included and compared with elderly individuals (n = 22) lacking apparent memory problems. We sampled 10 mL venous blood in citrate. Granulocytes were separated according to density in linear Percoll™ gradients. Subsequently, the gradients were divided into density subfractions (n = 16). In every fraction, determination of eosinophil and neutrophil counts was carried out.RESULTS:AD sufferers displayed less granulocytes in fractions nos. 13-15 containing light cells. For these fractions, the P-values proved to be (P < 0·001; not significant; P = 0·03) and (P = 0·01; P = 0·01; not significant), for eosinophils and neutrophils, respectively.CONCLUSIONS:The present work describes that less circulating light granulocytes are a feature of AD demented individuals. It is to hypothesize that it is a sign of impaired granulocyte turnover and cell damage. It is concluded that AD affects inflammatory cells in the periphery and that the behaviour of granulocytes in dementia is worthwhile further studies.

- This work investigates relationships between platelet density and reactivity. 21 individuals subject to coronary angiography were studied. Peak platelet density was analyzed using a newly developed electronic device. The apparatus measures light transmission through test tubes containing density-separated platelets, thus allowing an estimation of the platelet distribution in the gradient. A flow cytometry technique was used for determining platelet reactivity after stimulating with ADP. Platelet counts, mean platelet volumes, peak platelet density and platelet reactivity were determined immediately before (day 1) and 24 h after cardiac catheterization (day 2). For all parameters changes during the day of angiography were compared with platelet density alterations. The subjects were divided into two groups according to density changes at angiography. Group 1 individuals showed density alterations (i.e. day 2 – day 1 value) ≥–8 × 10–5 kg/l. In contrast, group 2 subjects either displayed density changes <–8 × 10–5 kg/l or grossly disturbed platelet density patterns on day 2. Before angiography both groups had similar platelet counts and volumes. Then platelet reactivity when stimulating with ADP did not differ significantly between the two groups. After angiography, the number of fibrinogen-positive cells when stimulating with ADP rose by 6 ± 8% for group 2 patients. The corresponding figure for group 1 was –1 ± 6%. The difference was significant (p = 0.01). No such relationships were found when comparing density alterations and changes of platelet counts and volumes. We conclude that in this study platelet density alterations at coronary angiography are inversely related to variations of platelet reactivity.

- The prognosis of coronary heart disease (CHD) has changed for the better. Type II diabetes mellitus (T2DM) complicates CHD and is associated with less favorable prospects and higher rates of coronary recurrence.149 individuals below 75 years of age subject to elective coronary angiography to evaluate chest pain were consented. Patients were eligible if they did not have a history of rheumatic disease. 51 individuals treated medically for T2DM were compared with the remaining subjects (n = 98). Blood samples were obtained before elective coronary angiography.A special designed optical apparatus was used to analyze peak platelet density. Platelet bound fibrinogen after provocation reflecting the activation of the GPIIb-IIIa receptor i.e. platelet reactivity was determined with the use of a flow cytometer.T2DM is associated with augmented platelet density (p < 0.001).Diabetic platelets displayed enhanced reactivity when stimulating with higher concentrations ADP (8.5 μmol/l) (p < 0.01) and TRAP-6 (74 μmol/l) (p < 0.001).DTII patients with stable angina pectoris showed enhanced platelet density, augmented platelet reactivity and increased MPV. Platelets are more reactive in DTII. More aggressive platelets may offer a explanation as to why DTII has an impact upon the prognosis of CHD.

- Platelets contain a substantial quantity of amyloid-precursor protein (APP) and β-amyloid. However, despite the large importance of APP and β-amyloid to dementia, little is known about platelets in sporadic Alzheimer dementia (AD). Furthermore, platelet heterogeneity influences human pathology and has been described to affect the progression of AD. This study investigated AD platelets with respect to density diversity and in vivo activity associated with density sub-fractions. We included 39 AD patients and used, as controls, 22 elderly individuals without apparent memory disorder. A continuous Percoll™ gradient covering the density span 1.04–1.09 kg/l provided the basis to divide platelets of whole blood into density fractions (n = 16). All platelet populations were evaluated accordingly. Platelet counts were determined electronically. A flow-cytometer was put to use to measure surface-bound fibrinogen as a measure of platelet in vivo activity. Samples obtained from patients diagnosed with sporadic AD contained platelets (fractions numbers 4–16) that circulated with significantly less surface-bound fibrinogen, i.e., their platelet activation in vivo was reduced, compared with controls. In particular, highly significant differences (p < 0.001) were obtained for the six less dense platelet populations (fractions numbers 11–16) when comparing sporadic AD with controls. In contrast, the densest AD platelets in fractions numbers 1–3 did not differ significantly from control cells with respect to in vivo platelet-bound fibrinogen. It is concluded that sporadic AD is characterized by lower density platelet populations that, while circulating, exhibited reduced activation. The clinical significance of this finding is unclear but these results suggest the importance of platelet heterogeneity in dementia as a topic for further investigation.

- Stroke is worldwide a leading cause of death and disability. Its etiology is regarded as heterogeneous. Platelets are implicated in its pathophysiology, but our understanding of their specific role is incomplete. Only sparse and conflicting information exists about platelet reactivity and activity in acute stroke. Some scientists take the view that platelets activate in conjunction with acute cerebral infarctions. Others put forward evidence corroborating the contrary notion. Increased soluble P-selectin as a sign of platelet and/or endothelial activity seems to be a feature of the disease. The latter point of view is opposed by other researchers. Due to these conflicting opinions, this study is devoted to platelet characteristics in acute cerebral infarctions. We studied subjects (n = 72; age 74 +/- 10(SD) years; 31 females) having acute stroke. As controls served atrial fibrillation (AF) patients (n = 58; age 69 +/- 7(SD) years; 12 females) subject to electrical cardioversion, a flow cytometer was put to use for measuring platelet reactivity and activity. After agonist provocation, both platelet bound P-selectin and fibrinogen were employed as estimates of platelet reactivity. Dilutions of a thrombin-receptor-activating peptide (TRAP-6) (74 and 57 mmol/l) (P-selectin and fibrinogen) and ADP (8.5 and 1.7 mmol/l) (fibrinogen only) were put to use as platelet agonists. Membrane-bound P-selectin without agonist stimulation served as a measure of in vivo platelet activation. Soluble P-selectin, as determined from a commercial ELISA, was used to assess platelet and/or endothelial activity. In acute stroke neither platelet-bound P-selectin nor fibrinogen after stimulation, i.e. reactivity, differed from AF controls. In contrast, lower platelet activity as judged from surface attached and circulating P-selectin without agonist stimulation proved to be a feature of cerebral infarctions. The p-values were p < 0.001 and p < 0.01, respectively. It is concluded that acute stroke is not associated with platelet reactivity platelets circulate less activated during the disease. It is evident that the mechanisms reflecting platelet reactivity and activity being investigated in this study play minor roles in stroke pathophysiology. New powerful platelet inhibitory drugs are currently introduced. To avoid major bleeding studies on platelet, behavior in acute stroke are necessary before including these medications in stroke treatment protocols.

- RationaleAccording to literature, the inflammatory response and platelets are associated with coronary heart disease mortality. In this study, we examine if similar relationships exist after acute cerebral infarctions.DesignBetween 2005 and 2007, individuals (n = 61) hospitalized with acute stroke were investigated 2.1 ± .3 (SD) days after hospital admission. After 9.3 ± .7 (SD) years, 29 patients (age 79 ± 8 [SD]; 12 women) had died. They were compared with survivors (age 69 ± 9 [SD]; 9 women) with respect to inflammatory parameters and platelet features such as activity and reactivity.Results and conclusionInflammation and platelets at the acute event do not forecast long-term survival of stroke sufferers

- ObjectivePlatelets may well be significant in the pathogenesis of cerebral infarction. Platelets vary substantially according to gender. The scope of our current work is to establish if female and male stroke sufferers differ regarding platelet reactivity.Patients and methods73 Consecutive individuals stricken by acute ischemic cerebral infarction (31 females, 42 males) participated. All stroke subtypes were included. Platelet counts was determined electronically. Platelet reactivity i.e. the presence of surface-bound fibrinogen following provocation was analyzed with a flow cytometer. ADP (1.7 μmol/L) and a thrombin receptor agonist (TRAP-6) (57 μmol/L) were the agonists used.ResultsFemale stroke sufferers had higher platelet counts (p = 0.013) but their platelets were less reactive. The p values were (p = 0.038) and (p = 0.016) for ADP and TRAP-6, respectively.ConclusionThe current study demonstrates that women suffering acute cerebral infarction have less reactive platelets. It is concluded that gender affects platelets. Our study indicates that it may be beneficial to individualize platelet inhibition of stroke sufferers according to gender.

- Background: Depression exists in mild, moderate, and severe depressive attacks.Evidence suggests that depression is linked to anemia. Several studies have establisheda correlation between depression and anemia. In previous studies, a venous blood samplewas normally used to analyze the average value of hemoglobin and parameters oferythrocytes. The current study examined full blood count (FBC) in different populationsof erythrocytes in individuals with depression (DE) compared to a healthy control group(CON).Material and Methods: All DE, n=24 were diagnosed with DSM-IV and ICD-10. CON,n=54 served as controls. A Percoll™ gradient was used to separate erythrocytes intodifferent density fractions. In all fractions, FBC, i.e., red blood cell count (RBC),hemoglobin concentration (Hb), mean corpuscular hemoglobin (MCH), mean bodyhemoglobin concentration (MCHC) and mean body volume (MCV) were analyzed usinga CELL-DYN 4000. As a comparison, a second blood sample was also taken, where themean values of FBC were analyzed.Results: When the mean value of FBC was analyzed, no significant difference was foundbetween the groups. In contrast, when erythrocytes were separated by density, a lesseramount of Hb was found amongst the smaller erythrocytes, i.e. fractions nos. 8-17 (p <0.05). No significant difference was found when measuring MCH and MCHC in the samedensity fractions.Conclusion: The current study provides evidence that smaller erythrocytes that weredivided by density have less hemoglobin. However, erythrocytes which were notseparated by density i.e. mean values of hemoglobin showed no difference between thegroups. For that reason, it may be of value to perform an extended analysis oferythrocytes and hemoglobin as a complement to the average value of hemoglobin. Thismay be of value when DE patients are investigated for anemia.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Fibromyalgia (FMS) is a pain syndrome characterized by chronic widespread pain and hyperalgesia/allodynia. Many affected are women and risk factors are unidentified. Today, a certain number of set criteria of disease signs and symptoms must be met for the diagnosis to be made. These criteria are used because of the lack of reliable biomarkers or other medical examination. The current study examines if in vivo platelet activity varies between FMS and controls without FMS.Material and Methods: The study involves 24 females (age 38 + 9 (SD) years) with diagnosed FMS. 25 healthy females (age 50 + 12 (SD) years) without FMS served as controls. After sampling the whole platelet population was separated according to density with a linear Percoll™, into 17 density fractions. Platelet counts was carried out in all fractions using a routine cell counter. In addition, a flow cytometer was used to measure platelet bound fibrinogen without platelet agonist, reflecting in vivo platelet activity.Results: The study groups did not differ with respect to the distribution of platelets in the gradient. FMS sufferers demonstrated a significant higher platelet bound fibrinogen in most of the platelet density fractions. In particular, significant differences (p < 0.05) were obtained in fractions numbers 2-14 and 16. In difference, fractions numbers 1, 15 and 17 did not show any significant variance.Discussion: This is the first study to examine in vivo platelet activity in FMS. The results indicate that FMS is associated with elevated in vivo platelet activity compared to individuals without FMS. The clinical significance and the biochemical mechanisms regarding platelet heterogeneity are still uncertain. The results stimulate further research to elucidate the importance of platelet diversity in FMS

- This study investigates relationships between platelet reactivity and coronary blood flow obstruction in stable angina pectoris. Consented were 36 patients with single-vessel disease. The subjects were divided into two groups. One group (n = 14) had less severe (< = 80%) and the second group (n = 22) had severe coronary flow impairment (90%). Before elective coronary angiography platelet in vitro reactivity in venous whole blood was determined using a flow cytometry technique. A thrombin-receptor activating peptide (TRAP-6) (0.77 and 0.06 g/l) and ADP (8.5 and 1.7 µmol/l) were used to activate platelets. The number of fibrinogen positive cells (%) i.e., activated platelets after stimulation was employed as experimental parameter. Less severe flow obstruction was associated with more reactive platelets. When stimulating with 0.77 g/l TRAP-6 the number of activated platelets was 64 ± 15 (SD)%. The corresponding value for the group with severe flow obstruction was 40 ± 17(SD)%. The difference is significant (P < 0.001). 0.06 g/l TRAP-6 yielded similar results (P < 0.01). Also when using 8.5 µmol/l ADP to challenge platelets less severe flow obstruction was associated with enhanced reactivity (P < 0.01). 1.7 µmol/l ADP generated comparable results (P < 0.05). Thus, in stable angina pectoris coronary flow obstruction is inversely related to platelet reactivity.

- BACKGROUND: The impact of atrial fibrillation (AF) upon platelet reactivity has not been investigated. METHODS: Subjects were 33 individuals with AF who consented to elective electrical cardioversion (ECV) immediately before ECV determination of surface-bound fibrinogen after stimulation i.e. platelet reactivity was carried out. A flow cytometer was employed. ADP (1.7 and 8.5mumol/L) and a thrombin receptor activating peptide (54 and 74mumol/L) were used as agonists. The analyses were repeated after 26+/-8(SD) months. RESULTS: Compared to day 1 subjects with AF (n=18) had a trend towards lower platelet reactivity at study end. It reached significance when using 1.7mumol/L ADP. In contrast, after 26+/-8(SD) months sinus rhythm (SR) (n=15) was associated with significant lower reactivity with all agonists. CONCLUSION: After 26+/-8(SD) months patients returning with AF had higher platelet reactivity than those who remained with SR.

Platelet Density Distribution in Essential Thrombocythemia
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Essential thrombocythemia (ET) is characterized by high platelet counts and a slightly increased bleeding risk. Why severe hemorrhage does not occur more frequently is not known. Variations of platelet density (kg/l) depend mainly on cell organelle content in that high-density platelets contain more alpha and dense granules. This study compares ET patients (n = 2) and healthy volunteers (n = 2) with respect to platelet density subpopulations. A linear Percoll gradient containing prostaglandin E(1) was employed to separate platelets according to density. The platelet population was subsequently divided by density into 16 or 17 subpopulations. Determination of platelet counts was carried out. In each density fraction, platelet in vivo activity, i.e. platelet-bound fibrinogen, was measured using a flow cytometer. To further characterize platelet subpopulations, we determined intracellular concentrations of CD40 ligand (CD40L) and P-selectin in all fractions. Patients and controls demonstrated similar density distributions, i.e. 1 density peak. High-density platelets had more surface-bound fibrinogen in conjunction with signs of platelet release reactions, i.e. with few exceptions they contained less CD40L and P-selectin. Peak density platelets showed less surface-bound fibrinogen. These platelets contained less CD40L and P-selectin than nearby denser populations. The light platelets had more surface-bound fibrinogen than peak platelets together with elevated concentrations of CD40L. In ET, the malignant platelet production could exist together with platelets originating from normal megakaryocytes. It is also possible that clonal megakaryocytes produce platelets covering the entire density span. The 'normal' density distribution offers a tenable explanation as to why serious bleedings do not occur more frequently.

Platelets : with special reference to platelet density subpopulations, stable coronary heart disease and atrial fibrillation
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The current thesis was divided into two parts. Basic platelet research is the topic of the first section. The subsequent clinical part examines platelet reactivity in stable angina pectoris (AP) and in atrial fibrillation.Platelet heterogeneity was investigated in the first section (papers 1 and 2). The cells were separated according to density using linear Percoll™ (a density medium) gradients. The latter contained EDTA, prostaglandin E1 and theophylline to prevent platelet in vitro activity. The platelet population was then divided into density subpopulations (n = 16 - 20). Membrane attached fibrinogen was determined with a flow cytometer technique and used as a marker reflecting platelet in vivo activity. Platelet P-Selectin content was employed to estimate the quantity of platelet α-granules. Paper I examined healthy blood donors (n = 3). The second report (paper II) compared healthy volunteers (n = 2) and subjects with essential thrombocythemia (ET) (n = 2). The latter is a clonal disease being characterized by an excessive platelet production. Platelet counts were determined in all fractions. In manuscripts I and II determination of surface bound fibrinogen and intracellular P-Selectin was carried out in 12 and 16 platelet density fractions, respectively.High density platelets displayed more surface bound fibrinogen indicating in vivo activity. They also contained less P-Selectin. The latter finding implies platelet in vivo release reactions. Low density platelets circulated with more surface bound fibrinogen as well. Compared with peak density platelets, lighter cells contained more P-Selectin. ET was characterized by a similar platelet density pattern in that high and low density platelets displayed more surface bound fibrinogen. The similarity may explain why severe bleedings do not occur more frequently in ET. It is also obvious from the current thesis that the significance of platelet heterogeneity remains unclear and stimulates to further research. In particular, future work must involve more patients.The second part (papers III-VI) of the thesis was devoted to stable AP and atrial fibrillation. Determination of platelet reactivity i.e. platelet bound fibrinogen after stimulation was carried out in whole blood. A flow cytometer technique was employed (papers III-VI). Adenosine diphosphate (ADP) (1.7 and 8.5 μmol/L) and a thrombin-receptor activating peptide (TRAP-6) (57 and 74 μmol/L) were used as stimulating agents. Determination of peak platelet density (kg/L) was utilized as a further measure reflecting platelet reactivity (paper V). Surface bound and soluble P-Selectin were employed as platelet activity markers (paper VI).Gender differences with respect to platelet reactivity were investigated in paper III. Paper IV examined platelets in stable AP without significant coronary flow obstruction(s) as determined by coronary angiography. In a following study platelet reactivity was analysed in diabetes type II complicated by stable AP (paper V). Finally, long-term (more than 2 years) outcome of atrial fibrillation was related to platelet reactivity and activity (paper VI). In this study the subjects were investigated at the initial electrical cardioversion and the analysis were repeated after more than 2 years.Postmenopausal women with stable AP demonstrated more reactive platelets when stimulating with TRAP-6. They had higher platelet counts (paper III) as well. Stable AP without significant coronary flow obstruction(s) was associated with elevated platelet reactivity (paper IV). Diabetes type II was linked to higher peak platelet density and elevated platelet reactivity (paper V). Augmented platelet reactivity proved to be a feature of subjects remaining in atrial fibrillation more than 2 years after the electrical cardioversion (paper VI). In contrast, the irregular heart rhythm did not affect platelet activity.It is to assume that platelets at least partly are responsible for the sometimes atypical symptoms of females with stable AP. It is also conceivable to speculate that platelets contribute to chest pain in AP free from significant coronary flow obstruction(s). Theoretically, enhanced platelet reactivity could at least partly explain why diabetes type II affects the prognosis of coronary heart disease. The thesis further shows a possible theoretical link between atrial fibrillation, increased platelet reactivity and clot formation.

- AIM OF THE STUDY: To investigate platelets and different inflammatory markers in conjunction with a substantial inflammatory reaction. We used individuals with active rheumatoid arthritis (RA) as an experimental cohort.METHODS: We selected 16 patients with active RA having at least one affected joint. On day 1, platelet and neutrophil counts together with C-reactive protein (CRP) were determined. We further analysed platelet volume (MPV) and plasma levels of thrombopoietin (TPO), P-selectin, myeloperoxidase and interleukin 6 (IL-6). After 2 years when all patients failed to show any swollen joints all analyses were repeated.RESULTS AND CONCLUSIONS: As expected platelet count, CRP and IL-6 were elevated in active RA. The measures correlated with each other thus reflecting the same characteristic of the inflammatory response. The neutrophil count, MPV and myeloperoxidase also mirror disease activity. They failed to correlate with other activity markers thus providing unique information. MPV and myeloperoxidase on day 1 correlated with recovery values. Therefore, they could be suitable to use when following the inflammatory reaction over a long period of time.

- Background: Learning in simulated nursing situations with advanced manikin is considered to prepare nursing students for clinical care situations. Collaboration with classmates facilitates the learning process which is described in the literature. The study aimed to investigate whether there are factors that nursing students describe as important for learning in a simulated care situation. Method: A mixed method was used in this study. Data were collected from (n=53) nursing students. At first, a quantitative data collection consisting of questionnaires was conducted one week before the simulation exercise. Thereafter, group interviews were conducted (n=7), which became a basis for the qualitative data collection. Results: The students described that they were well prepared for the skills training. Getting support in their learning from classmates and teachers was described as significant. Conclusion: Reflection of classmates’ processing of the situation work improves the student’s individual learning during the skills education with subsequent reflection with a teacher. In order for the learning to be optimal, collaboration with other fellow students in the base group is necessary.

- IntroductionProvision of mobile care at the home of patients appears to become necessary as the population becomes increasingly older. But there are challenges in moving emergency care from hospitals to the home of patients. The aim of the study was therefore to describe the experiences of the mobile care in Sweden.MethodSemi structured interviews were conducted with 12 persons with experience of mobile care in Sweden, such as nurses, physicians, civil servants and politicians. Qualitative latent content analysis was used as an analysis method.ResultThe results show that cooperation is of utmost importance to achieve functioning mobile care. Cooperation both on an inter-organizational level and on a close team-work is required for all of the involved parties in mobile care to take on a joint responsibility for the patient. As mobile care is primarily provided to elderly multimorbid patients, a comprehensive view on patient care is required in which the patient and their relatives experience security.ConclusionMobile care is seen as a moving care that comes to the seeking person and not the other way around. The resources are distributed where they make the most use, that is, closest to the individual. Mobile care is seen as a complement to the traditional hospital care. This means a different way of working that requires close collaboration between different categories of personnel and organizations, where there should not be any discussions about boundaries, rather, the discussion should include patients needs and situation instead.
