- Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5 < P-T,P-assoc < P-T,P-trig < 4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and p(T) bins, and the widths show no significant evolution with event multiplicity or p(T). These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge. (c) 2013 CERN. Published by Elsevier B.V. All rights reserved.

Journal article (peer-reviewed)abstract
- The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

Journal article (peer-reviewed)abstract
- Sheltered housing is a housing model that provides accessible apartments with elevated social possibilities for older people, which is expected to increase resident health and independence, reducing the need for care. As previous research on sheltered housing is scarce, the aim of this study was to explore the characteristics, health status and social participation of older people living in sheltered housing, compared to ageing in place. The study utilised baseline data from a matched cohort study survey on a nationally representative total population of residents in all sheltered housings in Sweden, and a matched control group (n = 3,805). The data collection took place between October 2016 and January 2017. The survey assessed functional capability using the Katz ADL and Lawton IADL scale, self-rated health using the EQ5D scale, and depressive mood using the GDS-4 scale. Descriptive statistics, frequencies, mean scores, independent t tests, p-values and effect sizes were utilised to compare the two groups. The results of the study show that older people living in sheltered housing, compared to ageing in place, had lower self-reported health (M = 64.68/70.08, p = <0.001), lower self-reported quality of life (M = 0.73/0.81, p = <0.001), lower functional status concerning activities of daily living (M = 5.19/5.40, p = <0.001), lower functional status concerning instrumental activities of daily living (M = 4.98/5.42 p = <0.001,), and higher probability of depressive mood (M = 0.80/0.58, p = <0.001). The results imply that residents in sheltered housing may have more care needs than those ageing in place. Further longitudinal comparative studies are needed to explore the impact residence in sheltered housing has on resident health and well-being.

Journal article (peer-reviewed)abstract
- Aims: To explore to what extent type of residence (sheltered housing or ageing in place) contributes to thriving and well-being in older adults, when controlling for age, sex, living alone, being a widow and adjusting for functional status, self-rated health, and depressive mood.Design: A matched cohort study.Methods A self-report survey was sent out to a total population of residents in all sheltered housings in Sweden and a matched control group ageing in place (N = 3,805). The data collection took place between October 2016-January 2017.Results: The interaction analyses related to thriving showed that with increasing level of depressive mood and decreasing levels of self-rated health and functional status, those residing in sheltered housing generally reported higher levels of thriving, as compared with those ageing in place. Well-being was not found to be significantly associated with type of accommodation.Conclusion: There may be features in sheltered housing that are associated with resident thriving especially among individuals with impairments of function, health or mood, although further studies are required to identify these specific features.Impact: This study informs staff and policymakers about thriving and well-being in sheltered housing accommodations. These findings may be used to further the development of sheltered housing accommodations.

The Umeå Ageing and health research programme (U-age) : exploring person-centred care and health promoting living conditions for an ageing population
- 2016
-
In: Nordic journal of nursing research. - : Sage Publications. - 2057-1585 .- 2057-1593. ; 36:3, s. 168-174

Journal article (peer-reviewed)abstract
- The aim of this article is to describe the Umeå ageing and health research programme that explores person-centred care and health-promoting living conditions for an ageing population in Sweden, and to place this research programme in a national and international context of available research evidence and trends in aged care policy and practice. Contemporary trends in aged care policy includes facilitating ageing in place and providing person-centred care across home and aged care settings, despite limited evidence on how person-centred care can be operationalised in home care services and sheltered housing accommodation for older people. The Umeå ageing and health research programme consists of four research projects employing controlled, cross-sectional and longitudinal designs across ageing in place, sheltered housing, and nursing homes. The research programme is expected to provide translational knowledge on the structure, content and outcomes of person-centred care and health-promoting living conditions in home care, sheltered housing models, and nursing homes for older people and people with dementia.

Impact of Diabetes Mellitus and Chronic Kidney Disease on Cardiovascular Outcomes and Platelet P2Y12 Receptor Antagonist Effects in Patients With Acute Coronary Syndromes : Insights From the PLATO Trial
- 2019
-
In: Journal of the American Heart Association. - 2047-9980 .- 2047-9980. ; 8:6
-
Journal article (peer-reviewed)abstract
- Background-There are limited data on how the combination of diabetes mellitus (DM) and chronic kidney disease (CKD) affects cardiovascular outcomes as well as response to different P2Y(12) receptor antagonists, which represented the aim of the present investigation. Methods and Results-In this post hoc analysis of the PLATO (Platelet Inhibition and Patient Outcomes) trial, which randomized acute coronary syndrome patients to ticagrelor versus clopidogrel, patients (n=15 108) with available DM and CKD status were classified into 4 groups: DM+/CKD+ (n=1058), DM+/CKD- (n=2748), DM-/CKD+ (n=2160), and DM-/CKD- (n=9142). The primary efficacy end point was a composite of cardiovascular death, myocardial infarction, or stroke at 12 months. The primary safety end point was PLATO major bleeding. DM+/CKD+ patients had a higher incidence of the primary end point compared with DM-/CKD- patients (23.3% versus 7.1%; adjusted hazard ratio 2.22; 95% CI 1.88-2.63; P<0.001). Patients with DM+/CKD- and DM-/CKD+ had an intermediate risk profile. The same trend was shown for the individual components of the primary end point and for major bleeding. Compared with clopidogrel, ticagrelor reduced the incidence of the primary end point consistently across subgroups (P-interaction=0.264), but with an increased absolute risk reduction in DM+/CKD+. The effects on major bleeding were also consistent across subgroups (P-interaction=0.288). Conclusions-In acute coronary syndrome patients, a gradient of risk was observed according to the presence or absence of DM and CKD, with patients having both risk factors at the highest risk. Although the ischemic benefit of ticagrelor over clopidogrel was consistent in all subgroups, the absolute risk reduction was greatest in patients with both DM and CKD.

Venous hemodynamic changes in lower limb venous disease : the UIP consensus according to scientific evidence
- 2016
-
In: International Journal of Angiology. - : Springer. - 0392-9590 .- 1827-1839. ; 35:3, s. 236-352

Journal article (peer-reviewed)abstract
- There are excellent guidelines for clinicians to manage venous diseases but few reviews to assess their hemodynamic background. Hemodynamic concepts that evolved in the past have largely remained unchallenged in recent decades, perhaps due to their often complicated nature and in part due to emergence of new diagnostic techniques. Duplex ultrasound scanning and other imaging techniques which evolved in the latter part of the 20th century have dominated investigation. They have greatly improved our understanding of the anatomical patterns of venous reflux and obstruction. However, they do not provide the physiological basis for understanding the hemodynamics of flow, pressure, compliance and resistance. Hemodynamic investigations appear to provide a better correlation with post-treatment clinical outcome and quality of life than ultrasound findings. There is a far better prospect for understanding the complete picture of the patient's disability and response to management by combining ultrasound with hemodynamic studies. Accordingly, at the instigation of Dr Angelo Scuderi, the Union Internationale de Phlebologie (UIP) executive board commissioned a large number of experts to assess all aspects of management for venous disease by evidence-based principles. These included experts from various member societies including the European Venous Forum (EVF), American Venous Forum (AVF), American College of Phlebology (ACP) and Cardiovascular Disease Educational and Research Trust (CDERT). Their aim was to confirm or dispel long-held hemodynamic principles and to provide a comprehensive review of venous hemodynamic concepts underlying the pathophysiology of lower limb venous disorders, their usefulness for investigating patients and the relevant hemodynamic changes associated with various forms of treatment. Chapter 1 is devoted to basic hemodynamic concepts and normal venous physiology. Chapter 2 presents the mechanism and magnitude of hemodynamic changes in acute deep vein thrombosis indicating their pathophysiological and clinical significance. Chapter 3 describes the hemodynamic changes that occur in different classes of chronic venous disease and their relation to the anatomic extent of disease in the macrocirculation and microcirculation. The next four chapters (Chapters 4-7) describe the hemodynamic changes resulting from treatment by compression using different materials, intermittent compression devices, pharmacological agents and finally surgical or endovenous ablation. Chapter 8 discusses the unique hemodynamic features associated with alternative treatment techniques used by the CHIVA and ASVAL. Chapter 9 describes the hemodynamic effects following treatment to relieve pelvic reflux and obstruction. Finally, Chapter 10 demonstrates that contrary to general belief there is a moderate to good correlation between certain hemodynamic measurements and clinical severity of chronic venous disease. The authors believe that this document will be a timely asset to both clinicians and researchers alike. It is directed towards surgeons and physicians who are anxious to incorporate the conclusions of research into their daily practice. It is also directed to postgraduate trainees, vascular technologists and bioengineers, particularly to help them understand the hemodynamic background to pathophysiology, investigations and treatment of patients with venous disorders. Hopefully it will be a platform for those who would like to embark on new research in the field of venous disease.
