RESUMO

BACKGROUND: Age-Related Macular Degeneration (AMD) is an eye disease associated with age that causes progressive and irreversible loss of central vision, while the peripheral visual ability remains. The occurrence of and especially late AMD is estimated to increase extensively to 2040 among persons aged ≥ 65 in Scandinavia, due to an increasing aging population. OBJECTIVES: The present study explored what it means to live with AMD through the eyes of those living with the condition. METHODS: This is an explorative interview study. People who were ≥ 65 years old, living in their own homes, and diagnosed with advanced dry AMD in one or both eyes, causing a visual acuity of no more than 0.3 or worse in the best eye, were invited to participate in the study. The method chosen was the constructivist grounded theory, where reality is seen as fundamentally social and processual and a way of accessing the participants' experiences, thoughts, and feelings. RESULTS: In total, 12 interviews were conducted. Living with dry AMD confronted different problems and challenges. The substantive theory, Perpetuating ability to live life as usual, is characterised by a desire to continue life as usual, which requires an acceptance of the disease's progress, self-acceptance of the new me, and an acceptance that the new life needs to be lived a little more carefully. Moreover, the participants used three strategies to resolve their main concern by maintaining an everyday life 1) Navigating the new normal, 2) Trusting own ability, and 3) Interdepending. CONCLUSION: Maintaining an everyday life is the primary concern among people with AMD. In supporting self-care, gaining information about the subjective experience to support their everyday living is of the utmost importance. This grounded theory captures valuable knowledge of how the older adults resolved their main concern "you got to keep on" despite their affected vision by "facing the fact" live life as usual since since life goes on. Our study also gives rise both to implications for research and practice in order to strengthen older people with AMD facing their future challenges.

RESUMO

INTRODUCTION: The relations between specific ECG patterns and coronary angiographic findings in cardiac arrest patients with different comorbidities are not properly assessed. More evidence is needed to identify patients with the highest risk for acute coronary artery disease as a cause of the cardiac arrest. This study aims to describe the coronary artery findings after cardiac arrest in relation to ECG and comorbidity. METHOD: A retrospective study of out-of-hospital cardiac arrest patients, with coronary angiography performed within 28 days. ECG on admission, comorbidity, PCI attempts and angiographic findings are described. Data were retrieved from national registries in Sweden. RESULTS: Among 1133 patients with available ECG and angiography information the mean age was 64 years. The rate of shockable rhythm was 79%. The total incidence of any significant stenosis in cardiac arrest patients without ST-elevation who underwent coronary angiography within 28 days was 71%. The incidence of any stenosis in patients with normal ECG was 62.1% and in patients with LBBB, 59.3%. In patients with ST-depression or RBBB, PCI attempts were made in 47.1% and 42.4% respectively, compared with 33.3% in patients with normal ECG. Among patients without ST-elevation, those with diabetes mellitus and those with initial shockable rhythm respectively, 84.8% and 71.5 had at least one significant stenosis. CONCLUSION: Our study suggests, that evaluation of ECG patterns and comorbidities in out-of-hospital cardiac arrest patients without ST-segment elevation may be important to identify those with a high risk of coronary artery lesions that could benefit from early revascularization.

RESUMO

BACKGROUND AND PURPOSE: Anaemia is associated with poor clinical outcome after ischaemic and haemorrhagic stroke. The association between anaemia and outcome in patients with cerebral venous thrombosis (CVT) was examined. METHODS: Consecutive adult patients with CVT were included from seven centres. Anaemia at admission was scored according to World Health Organization definitions. Poor clinical outcome was defined as a modified Rankin Scale score 3-6 at last follow-up. A multiple imputation procedure was applied for handling missing data in the multivariable analysis. Using binary logistic regression analysis, adjustments were made for age, sex, cancer and centre of recruitment (model 1). In a secondary analysis, adjustments were additionally made for coma, intracerebral haemorrhage, non-haemorrhagic lesion and deep venous system thrombosis (model 2). In a sensitivity analysis, patients with cancer were excluded. RESULTS: Data for 952 patients with CVT were included, 22% of whom had anaemia at admission. Patients with anaemia more often had a history of cancer (17% vs. 7%, P < 0.001) than patients without anaemia. Poor clinical outcome (21% vs. 11%, P < 0.001) and mortality (11% vs. 6%, P = 0.07) were more common amongst patients with anaemia. After adjustment, anaemia at admission increased the risk of poor outcome [adjusted odds ratio (aOR) 2.4, 95% confidence interval (CI) 1.5-3.7, model 1]. Model 2 revealed comparable results (aOR 1.9, 95% CI 1.2-3.2), as did the sensitivity analysis excluding patients with cancer (aOR 2.3, 95% CI 1.3-3.8, model 1). CONCLUSION: The risk of poor clinical outcome is doubled in CVT patients presenting with anaemia at admission.

RESUMO

In this paper, we describe and critically reflect on the possibilities and challenges of developing and implementing an empowerment-based school intervention regarding healthy food and physical activity (PA), involving participants from a Swedish multicultural area characterized by low socioeconomic status. The 2-year intervention was continually developed and implemented, as a result of cooperation and shared decision making among researchers and the participants. All 54 participants were seventh graders, and the intervention comprised health coaching, health promotion sessions and a Facebook group. We experienced that participants valued collaborating with peers, and that they took responsibility in codeveloping and implementing the intervention. Participants expressed feeling listened to, being treated with respect and taken seriously. However, we also experienced a number of barriers that challenged our initial intentions of aiding participation and ambition to support empowerment. Moreover, it was challenging to use structured group health coaching and to work with goal-setting in groups of participants with shared, and sometimes competing, goals, wishes and needs related to food and PA. Successful experiences from this intervention was the importance of acquiring a broad and deep understanding of the context and participants, being open to negotiating, as well as adjusting the intervention.

RESUMO

Essentials The risk of cerebral venous thrombosis (CVT) in patients with cancer is not known. We performed a case-control study including 594 patients with CVT and 6278 controls. History of cancer increased the risk of CVT approximately 5-fold. The association was strongest with hematological cancer in the first year after diagnosis. SUMMARY: Background Cancer is an established risk factor for leg vein thrombosis and pulmonary embolism. Controlled studies assessing the risk of cerebral venous thrombosis (CVT) in patients with cancer have not been performed. Objective To assess whether cancer is a risk factor for CVT. Patients/Methods This was a case-control study. We assessed consecutive adult patients with CVT from three academic hospitals from 1987 to 2015, and control subjects from the Dutch MEGA study (Multiple Environmental and Genetic Assessment of risk factors for venous thrombosis). We adjusted for age, sex and oral contraceptive use, and stratified for type of cancer and time since diagnosis of cancer. Results We included 594 cases and 6278 controls. In total, 53 cases (8.9%) and 160 controls (2.5%) had a history of cancer. Cases were younger (median 42 vs. 48 years), more often female (68% vs. 54%) and more often used oral contraceptives (55% vs. 23%) than controls. The risk of CVT was increased in patients with cancer compared with those without cancer (adjusted odds ratio [aOR], 4.86; 95% confidence interval [CI], 3.46-6.81). Patients with a hematological type of cancer had a higher risk of CVT (aOR, 25.14; 95% CI, 11.64-54.30) than those with a solid type of cancer (aOR, 3.07; 95% CI, 2.03-4.65). The association was strongest in the first year after diagnosis of cancer (hematological aOR, 85.57; 95% CI, 19.70-371.69; solid aOR, 10.50; 95% CI, 5.40-20.42). Conclusions Our study indicates that cancer is a strong risk factor for CVT, particularly within the first year of diagnosis and in patients with a hematological type of cancer.

RESUMO

Despite ethnic differences in allele frequencies of variants in dopaminergic genes associated with dopamine D2/D3 receptor availability (D2R), no study to date has investigated the relationship between genetic ancestry and striatal D2R. Here, we show that ancestry-informative markers significantly predict dorsal striatal D2R in 117 healthy ethnically diverse residents of the New York metropolitan area using Positron Emission Tomography (PET) with [11C]raclopride (P<0.0001), while correcting for age, sex, BMI, education, smoking status, and estimated socioeconomic status (ZIP codes). Effects of ethnicity on D2R were not driven by variation in dopaminergic candidate genes. Instead, candidate gene associations with striatal D2R were diminished when correcting for ancestry. These findings imply that future studies investigating D2 receptor genes should covary for genetic ancestry or study homogeneous populations. Moreover, ancestry studies on human neurobiology should control for socioeconomic differences between ethnic groups.

RESUMO

OBJECTIVES: Few studies have investigated long-term functional outcome in patients with cerebral venous thrombosis (CVT). We aimed to evaluate return to work (RTW) after CVT and its association with self-reported life satisfaction, quality of life, health, participation, fatigue, depression, and anxiety. METHODS: From hospital records, we identified all patients diagnosed with CVT in Sahlgrenska University Hospital between 1996 and 2016 and invited all survivors to a clinical follow-up visit >1 year after onset. Primary outcome was RTW within the follow-up period which was defined as ≥50% of gainful work or equivalent activity. Patients that were >62 years when they developed CVT were excluded. Cox regression analyses identified associated factors to RTW and Mann-Whitney U tests compared distributions of self-reported questionnaires on life satisfaction and health. RESULTS: Of 62 eligible and consenting patients (median age: 41.5 years (28.75-51.0); 61.3% female), 44 (71.0%) did RTW within the follow-up period (median 135 months, IQR 64-197). Median time to RTW was 7.0 months (IQR 1.4-12.7). Female sex (HR = 0.50, 95% CI = 0.25-0.99, P = .049) and parenchymal lesion detected during acute hospital stay (HR = 0.45, 95% CI = 0.24-0.82, P = .009) were significantly associated with no RTW. Patients with RTW reported significantly higher life satisfaction, quality of life, health, participation and lesser impact of fatigue, depression, and anxiety. CONCLUSIONS: Return to work after CVT is associated with higher life satisfaction, participation, and health. Parenchymal lesion in acute phase and female sex were associated with no RTW. Despite the young age of the patients, a significant portion did not regain working ability.

RESUMO

Interacting one-dimensional quantum systems play a pivotal role in physics. Exact solutions can be obtained for the homogeneous case using the Bethe ansatz and bosonisation techniques. However, these approaches are not applicable when external confinement is present. Recent theoretical advances beyond the Bethe ansatz and bosonisation allow us to predict the behaviour of one-dimensional confined systems with strong short-range interactions, and new experiments with cold atomic Fermi gases have already confirmed these theories. Here we demonstrate that a simple linear combination of the strongly interacting solution with the well-known solution in the limit of vanishing interactions provides a simple and accurate description of the system for all values of the interaction strength. This indicates that one can indeed capture the physics of confined one-dimensional systems by knowledge of the limits using wave functions that are much easier to handle than the output of typical numerical approaches. We demonstrate our scheme for experimentally relevant systems with up to six particles. Moreover, we show that our method works also in the case of mixed systems of particles with different masses. This is an important feature because these systems are known to be non-integrable and thus not solvable by the Bethe ansatz technique.

RESUMO

AIM: The reported incidence of injuries due to cardiopulmonary resuscitation using manual chest compressions (manual CPR) varies greatly. Our aim was to elucidate the incidence of CPR-related injuries by manual chest compressions compared to mechanical chest compressions with the LUCAS device (mechanical CPR) in non-survivors after out-of-hospital cardiac arrest. METHODS: In this prospective multicentre trial, including 222 patients (83 manual CPR/139 mechanical CPR), autopsies were conducted after unsuccessful CPR and the results were evaluated according to a specified protocol. RESULTS: Among the patients included, 75.9% in the manual CPR group and 91.4% in the mechanical CPR group (p=0.002) displayed CPR-related injuries. Sternal fractures were present in 54.2% of the patients in the manual CPR group and in 58.3% in the mechanical CPR group (p=0.56). Of the patients in the manual CPR group, there were 64.6% with at least one rib fracture versus 78.8% in the mechanical CPR group (p=0.02). The median number of rib fractures among patients with rib fractures was 7 in the manual CPR group and 6 in the mechanical CPR group. No CPR-related injury was considered to be the cause of death. CONCLUSION: In patients with unsuccessful CPR after out-of-hospital cardiac arrest, rib fractures were more frequent after mechanical CPR but there was no difference in the incidence of sternal fractures. No injury was deemed fatal by the pathologist.

RESUMO

Recent observed changes in Earth's climate, to which humans have contributed substantially, are affecting various health outcomes. These include altered distributions of some infectious disease vectors (ticks at high latitudes, malaria mosquitoes at high altitudes), and an uptrend in extreme weather events and associated deaths, injuries and other health outcomes. Future climate change, if unchecked, will have increasing, mostly adverse, health impacts - both direct and indirect. Climate change will amplify health problems in vulnerable regions, influence infectious disease emergence, affect food yields and nutrition, increase risks of climate-related disasters and impair mental health. The health sector should assist society understand the risks to health and the needed responses.

RESUMO

PURPOSE: Leadership can positively affect the work environment and health. Communication and dialogue are an important part in leadership. Studies of how dialogue is valued and handled in first-line leadership have not so far been found. The aim of this study is to develop a theoretical understanding of how first-line leaders at hospitals in western Sweden value and handle dialogue in the organisation. DESIGN/METHODOLOGY/APPROACH: The study design was explorative and based on grounded theory. Data collection consisted of interviews and observations. A total of 11 first-line leaders at two hospitals in western Sweden were chosen as informants, and for four of them observation was also used. FINDINGS: One core category emerged in the analysis: leaders' communicative actions, which could be strategically or understanding-oriented, and experienced as equal or unequal and performed equitably or inequitably, within a power relationship. Four different types of communicativeactions emerged: collaborative, nurturing, controlling, and confrontational. Leaders had strategies for creating arenas and relationships for dialogue, but dialogue could be constrained by external circumstances or ignorance of the frameworks needed to conduct and accomplish dialogue. PRACTICAL IMPLICATIONS: First-line leaders should be offered guidance in understanding the consequences of consciously choosing and strengthening the communication component in leadership. ORIGINALITY/VALUE: The positive valuation of dialogue was not always manifest in practical action. One significant consequence of not using dialogue was that information with impact on organisational efficiency and finances was communicated upwards in the management system.

RESUMO

The distributional area of the tick Ixodes ricinus (L.), the primary European vector to humans of Lyme borreliosis spirochaetes (Borrelia burgdorferi sensu lato) and tick-borne encephalitis virus, appears to be increasing in Sweden. It is therefore important to determine which environmental factors are most useful to assess risk of human exposure to this tick and its associated pathogens. The geographical distribution of I. ricinus in Sweden was analysed with respect to vegetation zones and climate. The northern limit of I. ricinus and B. burgdorferi s.l. in Sweden corresponds roughly to the northern limit of the southern boreal vegetation zone, and is characterized climatically by snow cover for a mean duration of 150 days and a vegetation period averaging 170 days. The zoogeographical distribution of I. ricinus in Sweden can be classified as southerly-central, with the centre of the distribution south of the Limes Norrlandicus. Ixodes ricinus nymphs from 13 localities in different parts of Sweden were examined for the presence of B. burgdorferi s.l. and found to be infected with Borrelia afzelii and Borrelia garinii. Tick sampling localities were characterized on the basis of the density of Borrelia-infected I. ricinus nymphs, presence of specific mammals, dominant vegetation and climate. Densities of I. ricinus nymphs and Borrelia-infected nymphs were significantly correlated, and nymphal density can thus serve as a general indicator of risk for exposure to Lyme borreliosis spirochaetes. Analysis of data from this and other studies suggests that high densities of Borrelia-infected nymphs typically occur in coastal, broadleaf vegetation and in mixed deciduous/spruce vegetation in southern Sweden. Ixodes ricinus populations consistently infected with B. burgdorferi s.l. can occur in: (a) biotopes with shrews, rodents, hares and birds; (b) biotopes with shrews, rodents, hares, deer and birds, and (c) island locations where the varying hare (Lepus timidus) is the only mammalian tick host.

RESUMO

Zoonotic tick-borne diseases are an increasing health burden in Europe and there is speculation that this is partly due to climate change affecting vector biology and disease transmission. Data on the vector tick Ixodes ricinus suggest that an extension of its northern and altitude range has been accompanied by an increased prevalence of tick-borne encephalitis. Climate change may also be partly responsible for the change in distribution of Dermacentor reticulatus. Increased winter activity of I. ricinus is probably due to warmer winters and a retrospective study suggests that hotter summers will change the dynamics and pattern of seasonal activity, resulting in the bulk of the tick population becoming active in the latter part of the year. Climate suitability models predict that eight important tick species are likely to establish more northern permanent populations in a climate-warming scenario. However, the complex ecology and epidemiology of such tick-borne diseases as Lyme borreliosis and tick-borne encephalitis make it difficult to implicate climate change as the main cause of their increasing prevalence. Climate change models are required that take account of the dynamic biological processes involved in vector abundance and pathogen transmission in order to predict future tick-borne disease scenarios.

RESUMO

This study investigates how scores on the Social Physique Anxiety Scale (SPAS) and the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) relate to Bratman's orthorexia test (BOT) scores with regard to age, sex, and self-reported exercise frequency and duration in a sample of Swedish participants in fitness center activities. A total of 251 participants (166 women and 85 men) completed the SPAS, the SATAQ, and a questionnaire focusing on exercise frequency and duration. The results indicated that the SATAQ subdomain internalization could itself explain the variation in BOT results. In women, the results indicated that exercise frequency, followed by SPAS score and the SATAQ subdomains internalization and awareness, could together explain the variation in BOT results. Fitness centers could make a point of emphasizing that some physical ideals are neither healthy nor realistic, thus strengthening member self-image and preventing social physique anxiety, eating disorders, and negative attitudes toward appearance.

RESUMO

AIM: We examined whether compensatory changes after adenosine A(1) receptor knockout [A(1)R (-/-)] eliminate the antilipolytic actions mediated by this receptor. METHODS: Lipolysis experiments were performed on adipocytes prepared from the wild type A(1)R (+/+), A(1)R (-/-) and heterozygous mice. Gene expression was assayed with cDNA microarray technique and real-time PCR; protein expression with immunoblotting. RESULTS: The A(1)R was the only adenosine receptor involved in lipolysis. The effects of adenosine deaminase and 2-chloroadenosine were abolished in A(1)R (-/-) mice. The IC(50) value of 2-chloroadenosine doubled from 16.6 to 33.6 nm when half of the A(1)Rs were eliminated. Adrenergic alpha(2) agonists had no effects on lipolysis. Prostaglandin E(2) (PGE(2)) inhibited lipolysis with an IC(50) value of 5.8 nm (4.7-7.2 nm) in the A(1)R (+/+) mice and 10.6 nm (9.0-12.6 nm) in the A(1)R (-/-) mice. Nicotinic acid inhibited lipolysis with an IC(50) value of 0.30 microm (0.19-0.46 microm) in the A(1)R (+/+) mice and 0.24 microm (0.16-0.37 microm) in the A(1)R (-/-) mice. G(i)alpha(1) mRNA was significantly up-regulated in adipose tissue from A(1)R (-/-) mice. However, immunoblotting showed that G(ialpha1) was not up-regulated at the protein level. CONCLUSION: The A(1)R mediates the antilipolytic actions of adenosine. Deletion of the A(1)R in mice does not result in compensatory increases in G-protein-mediated antilipolytic actions of PGE(2) or nicotinic acid.

RESUMO

Chronic heart failure is associated with a bad prognosis with considerably shortened survival and repeated hospitalisations. Patients suffering from heart failure also have symptoms that can affect their food intake, for example, tiredness when strained, breathing difficulties and gastrointestinal symptoms like nausea, loss of appetite and ascites. Pharmacological therapy can lead to a loss of appetite, which will make the intake of food inadequate to fill the required energy and nutritional needs. The nurse's interest in and knowledge of diet issues can improve these patients' nutritional status. The aim of this literature review was to describe the nurse's interventions regarding malnutrition in patients suffering from chronic heart failure. The literature search gave 13 articles, which were analysed, and sentences whose content was related to the aim were identified. Three areas of content appeared; drug treatment and consequences, gastrointestinal effects, and information and education. The results show that the nutritional status of these patients can be significantly improved by means of simple nursing interventions. Future research should focus on controlled experimental studies to evaluate differences in body weight, body mass index and quality of life between patients suffering from chronic heart failure, who are taking part in a fully enriched nutrition intervention, and patients suffering from chronic heart failure, who are eating their normal diet.

RESUMO

BACKGROUND: The incidence of tick-borne encephalitis (TBE) in Sweden has substantially increased since the mid-1980s. During the same period the climate has become milder and ticks have become more abundant. We investigated whether there is a link between the change in climate and the increase in incidence of TBE. METHODS: Since the late 1950s all cases of encephalitis admitted in Stockholm County have been serologically tested for TBE. We analysed the period 1960-98 with multiple regressions. The number of days per season with temperatures of known importance for tick prevalence and pathogen transmission were studied. 2 years of temperature data were related to each TBE incidence rate to account for the tick's long life-span. FINDINGS: Increases in disease incidence was significantly related (R(2)=0.58; p<0.0001) to a combination of two consecutive mild winters, temperatures favouring spring development (8-10 degrees C) and extended autumn activity (5-8 degrees C) in the year prior to the incidence year, and temperatures allowing tick activity (5-8 degrees C) early in the incidence year. INTERPRETATIONS: The findings indicate that the increase in TBE incidence since the mid-1980s is related to the period's change towards milder winters and early arrival of spring. Other factors may have influenced TBE incidence such as more people in endemic locations, and increases in host animal populations; factors which are partly climate related. Access to TBE vaccination since 1986 and increased awareness of ticks might have caused an underestimation of the links found. Our findings also suggest that the incidence of other tick-borne zoonoses might have been affected by the milder climate.

RESUMO

The CREM (cAMP-response-element modulator) gene product ICER (induced cAMP early repressor) has been proposed to function as a tumour (cell proliferation) suppressor. To investigate the generality of this concept, the expression pattern of ICER in brown adipocytes was followed; this was critical because brown adipocytes are one of few cell types in which cAMP is associated positively with cell proliferation but negatively with apoptosis. In response to the physiological stimulus of cold (which induces cell proliferation), ICER mRNA levels were increased in brown adipose tissue in vivo. In brown adipocytes in primary culture, ICER gene expression was induced by noradrenaline (norepinephrine) not only in the mature state (where noradrenaline potentiates differentiation), but also in the proliferative state of the cell cultures (where noradrenaline enhances cell proliferation). The induction was mediated via beta-receptors and the cAMP/protein kinase A pathway. The induced ICER appeared to repress its own expression and that of the beta2-adrenoceptor. It is thus evident that also in cell types in which cAMP induces proliferation, and even when these cells are in the proliferative state, ICER expression is induced by the same agents that stimulate proliferation. This can either mean that ICER is not a general tumour suppressor, or that brown adipocytes temporally or spatially avoid this role of ICER.

RESUMO

The implantable cardioverter-defibrillator (ICD) is today widely used for the treatment of sudden cardiac near-death episodes as a result of malignant ventricular dysrhythmia. After examining the literature, only four descriptive studies, all carried out in the USA, with a qualitative analysis based on ICD-patients' own perspectives on their life situation have been found. The aim of this study was to describe how patients living with an ICD-device in south-western Sweden conceive their life situation. As the focus was on patients' conceptions seen from a holistic perspective, an analysis inspired by phenomenography was employed on a strategic sample of 15 ICD-patients. Six categories emerged: a feeling of safety, a feeling of gratitude, a feeling of being, having a network, having a belief in the future, and gaining awareness. Although the findings cannot be generalized because of the descriptive research design, they illuminate the beneficial as well as intrusive effects of such a device, and emphasize the need for support groups for patients and families as well as further education for personnel in hospital and primary health care.
