Comparisons of recycled manure solids and wood shavings/sawdust as bedding material -implications for animal welfare, herd health, milk quality and bedding costs in Swedish dairy herds. J Dairy Sci 2024:S0022-0302(24)00630-1.

Abstract
Increasing shortages and costs of common bedding materials have led dairy farmers in Sweden to consider using recycled manure solids (RMS), which are readily available and low-cost, as an alternative bedding material. The main risks are effects on udder health and milk quality, but RMS could also affect animal welfare and claw health. The advantages and disadvantages of using RMS bedding have not been fully investigated, and findings in other countries cannot be directly applied to Swedish conditions and climate. This observational cross-sectional study investigated the use of RMS as bedding regarding associations with certain aspects of animal welfare, herd health, milk quality, and bedding costs in Swedish dairy herds. Thirty-four dairy farms using RMS or wood shavings/sawdust (each n = 17) were compared. Each farm was visited 2 times during the housing period 2020-2021, once in October-December and once in March-May. Dairy barns were observed, animal welfare was assessed, and free-stall dimensions were measured. Farm owners were interviewed about housing system characteristics, herd performance, and herd management. Data on milk production and herd health were obtained from the Swedish official milk recording scheme for the indoor period October-March. The prevalence of claw disorders and abnormal claw conformation were collected from the national claw health database for the period, October-May. On each farm visit, composite samples of unused bedding outside the barn and used bedding material from the free stalls, respectively, were taken for total bacterial count and dry matter analysis. Samples of bulk tank milk for determination of total bacterial count were taken in connection to the visits. In addition, samples of unused and used bedding material and manure from alleys for analysis of 3 Treponema species associated with digital dermatitis (DD) were gathered and analyzed. Total bacterial count was significantly higher in unused (8.50 log10 cfu/g) and used RMS bedding (9.75 log10 cfu/g) than in wood shavings/sawdust (used 4.74; unused 8.63 log10 cfu/g), but there were no significant differences in bulk milk total bacterial count (median 4.07 versus 3.89 log10 cfu/mL) or somatic cell count (median 243,800 versus 229,200 cells /mL). The aspects of animal welfare that were assessed did not differ significantly between the 2 bedding systems, while the prevalence of total claw disorders (25.9 versus 38.0% of trimmed cows), dermatitis (6.9 versus 16.2% of trimmed cows) and sole ulcers (2.0 versus 4.0% of trimmed cows) were significantly lower in the RMS herds. Treponema spp. were not detected in unused RMS material, but all RMS herds had presence of DD recorded at foot trimming. An economic assessment based on the interview results and price level from winter 2021 revealed that the costs of RMS bedding varied with amount of RMS produced. Thus, RMS is a potential alternative bedding material for dairy cows in Sweden and can be a profitable option for large dairy herds. However, the high level of total bacteria in the material requires attention to bedding and milking routines as well as regular monitoring of herd health.

Ventricular-arterial coupling (VAC) in a population-based cohort of middle-aged individuals: The STANISLAS cohort. Atherosclerosis 2023; 374:11-20. [PMID: 37159989 DOI: 10.1016/j.atherosclerosis.2023.04.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 04/15/2023] [Accepted: 04/21/2023] [Indexed: 05/11/2023]
Abstract
BACKGROUND AND AIMS Data exploring normal values of different ventricular-arterial coupling (VAC) parameters and their association with anthropometric and cardiovascular (CV) factors are scarce. We aim to report values of two different methods of VAC assessment according to age and sex and explore their association with CV factors within a large population-based cohort of middle-aged individuals. METHODS For 1333 (mean age 48 ± 14) individuals participating in the 4th visit of the STANISLAS cohort, VAC was assessed by two methods [1]: arterial elastance (Ea)/end-systolic elastance (Ees) and [2] Pulse wave velocity (PWV)/Global longitudinal strain (GLS). RESULTS The mean values of Ea/Ees and PWV/GLS were 1.06 ± 0.20 and 0.42 ± 0.12, respectively. The two methods of VAC assessment were poorly correlated (Pearson's correlation coefficient r = 0.14 (0.08; 0.19)). Increased PWV/GLS was associated with older age and a higher degree of cardiovascular risk factors (i.e., BMI, blood pressure, LDL, diabetes, hypertension) in the whole population as well as in the parent generation. In contrast, higher Ea/Ees were associated with decreasing age, and lower prevalence of risk factors in the whole cohort but neutrally associated with risk factors in the parent generation. CONCLUSIONS Higher PWV/GLS is significantly associated with CV factors regardless of age. In contrast, worse Ea/Ees is associated with a better CV risk profile when considering individuals aged 30 to 70 but neutrally associated with CV factors when considering only older patients. These results may suggest that PWV/GLS should preferably be used to explore VAC. In addition, age-individualized threshold of Ea/Ees should be used.

Abstract
Unhealthy food habits are included in the factors behind several severe health conditions. Their unequal distribution in the population has a complex background. Putting the problem “How can we make our resources more reachable?” instead of “How can we reach these groups?” changes focus from individual to organisational health literacy which opens windows of opportunity. A public health unit with commission to contribute to close health gaps identified a need to systematically develop its own health literacy. Critical examining was conducted by the quan/qual tool Health equlibrium methodology. Reflections on accessability and acceptability of resources offered by the unit were documented and used for methodolocigal development. Aims were to develop professional judgment on how to contribute to fair health outcome and to improve support for healthy habits. Data used were collected 2019-2021.What hinders people from healthier food habits? How can we adjust our practice? Documentation included organised breakfast-talks, food-talk with cultural interpreters, lectures with sports-club health ambassadors, health groups with people of different maternal language, meetings with parents at open pre-school, staff in health promotion commissions and elderly. Problems identified were high costs on healthy food and on travels to vending points, traditional large sugar-intake, marketing of unhealthy food to children, failure to understand information from Swedish Food Agency (except the Keyhole food labelling which was much appreciated). A model for shop-walks with cultural interpreters, more accessible versions of leaflet-materials and dialogue-meetings about food in different settings were developed. Reflections on the unit's communication lead to change of settings for meetings and refined ways to talk about parenthood, women's role and aspects of ethnicity. Systematic self-reflection strenghtens organisational health literacy and may contribute to fair health outcomes Key messages

Abstract
Abstract
Background
Patients with myocardial infarction (MI) have a high prevalence of diabetes mellitus (DM). Prognosis in patients with MI and DM is substantially worse than for those without DM. An unacceptably high proportion of patients with DM remain both undiagnosed and undertreated despite follow-up at cardiac rehabilitation (CR) centres.
Purpose
Using nationwide survey and registry data to investigate associations of clinical routines for DM screening and treatment at CR centres in Sweden with detection and treatment of DM at one-year post-MI.
Methods
Data on CR clinical routines were derived from the Perfect-CR survey, evaluating structures and follow-up processes at CR centres in Sweden (n=78). The response rate was 100% and missing data was minimal. Clinical routines for DM screening and treatment during CR (exposures) included the following: 1) laboratory assessments of fasting glucose and/or HbA1c as a part of initial patient assessment by a nurse, 2) routine use of oral glucose tolerance test (OGTT), 3) joint case rounds with diabetologists, and 4) whether diabetes medication is adjusted by cardiologists. Patient baseline and outcome data was derived from the national quality registry SWEDEHEART (n=7549). Primary outcome was DM incidence at one-year post-MI. Secondary outcome was the proportion of patients receiving diabetes medication other than insulin (secondary outcome). The association between exposures (for each clinical routine and cumulatively [0–4 work routines]) and outcomes was estimated using unadjusted and adjusted logistic regression, adjusting for relevant covariates.
Results
Number (%) of CR centres applying each of the clinical routines is shown in Table 1. The most common routine applied was fasting glucose and/or HbA1c being routinely evaluated at initial patient assessment (n=48 (62%)), while the least common was CR centres having joint case rounds with diabetologists (n=7 (9%)). Twenty (26%) CR centres did not apply any of the clinical routines while 7 (9%) centres applied 3 or 4 routines. Unadjusted and adjusted odds ratios (OR) with 95% confidence intervals (CI) for incident DM are shown in Figure 1. Compared to not applying any routines, 1) applying one or more routines was positively associated higher DM incidence at one-year post-MI (p for trend in unadjusted and adjusted models <0.001. Figure 1), and 2) at centres where all four working routines were applied, the odds for patients being treated with diabetes medication was significantly higher (crude OR 2.37 [1.80–3.13], adjusted OR 1.78 [1.19–2.66]).
Conclusion
Applying structured clinical routines for DM screening and treatment within CR can improve detection and treatment of DM in patients with MI

Cerebral saturation is associated with physical activity and post-discharge mortality in heart failure patients. Eur Heart J 2022.

Abstract
Abstract
Background
The cross-sectional relationship between heart failure (HF) and cerebral oxygenation has been studied in the past but the prognostic significance of this relationship has been limited. Here, we aimed to assess the role of cerebral tissue oxygen saturation (SctO2) as a risk factor for HF mortality and rehospitalization as well as evaluate the association between SctO2 with physical activity in a Swedish prospective HF cohort.
Methods
Ninety-five patients hospitalized for HF (mean age 70 years; 21% women) were examined with near-infrared spectroscopy (NIRS) and screened for physical activity derived from questionnaires in the Swedish national public health survey. The median follow-up time to death and re-hospitalization was 1377 (interquartile range, 245–2392) and 293 (14–2363) days, respectively. Associations between SctO2 at rest, post-discharge mortality and re-hospitalization were analyzed using multivariable Cox regression analysis adjusted for age, sex, body-mass index, smoking, prevalence of atrial fibrillation, prevalence of diabetes and systolic blood pressure. The associations between SctO2 and self-reported physical activity were explored by using logistic regression analysis adjusted for the aforementioned risk factors.
Results
A total of 25 patients (26%) reported to be engaged in physical activity less than one hour throughout the week. In the fully adjusted Cox regression model, low SctO2 at rest was associated with post-discharge mortality (HR, 0.77; CI, 0.66–0.91; p=0.002). However, low SctO2 was not associated with post-discharge rehospitalization risk (HR, 0.94; CI, 0.88–1.01; p=0.092). In the fully adjusted logistic regression models, low SctO2 at rest was associated with decreased physical activity (<1h per week), (OR 1.22; CI, 1.05–1.42; p=0.01).
Conclusion
We have demonstrated that low cerebral tissue oxygen saturation at rest is associated with post-discharge mortality in patients hospitalized for HF, independently of traditional risk factors. In addition, low cerebral tissue oxygen saturation at rest is associated with low physical activity. These findings highlight the role of cerebral saturation as a risk factor for cardiovascular prognosis, as well as underline the potential importance of taking cerebral perfusion into account when treating for heart failure.

Abstract
Abstract
Background
Selenium deficiency has been associated with all-cause and cardiovascular mortality, incident cardiovascular disease (coronary artery disease, myocardial infarction and stroke), and with poor prognosis in patients with acute heart failure (HF). Furthermore, high selenium levels were recently shown to be associated with reduced mortality and reduced incidence of HF in non-smokers.
Purpose
To examine if selenoprotein-P (SELENOP), a main carrier protein of selenium, is associated with incident HF.
Methods
SELENOP concentrations were measured in 5060 randomly selected subjects from the population-based prospective cohort study “the Malmö Preventive Project” (n=18240) using a validated ELISA approach. After exclusion of subjects with prevalent HF (n=230), complete data on all co-variates was available in 4803 subjects (1400 women (29.1%), mean age 69.6±6.2 years, 885 (19.7%) current smokers). SELENOP was continously related to risk of incident HF using Cox regression models adjusted for age, sex, body mass index, systolic blood pressure, anti-hypertensive treatment, smoking status, diabetes status, low-density lipoprotein cholesterol levels, and prevalent coronary events. Further, subjects within the lowest SELENOP quintile were compared to subjects in the remaining four quintiles in an adjusted model.
Results
Each 1 SD increment in SELENOP levels was associated with lower risk of incident HF (n=436) during a median follow-up period of 14.7 years (interquartile range 10.9–15.7 years, hazard ratio (HR) 0.92, 95% confidence interval (95% CI) 0.84–0.99; p=0.049 in a model adjusted for cardiovascular risk factors. Multivariate quintile analyses revealed that the subjects in the lowest SELENOP quintile were at the highest risk of incident HF in an adjusted model (HR 1.46; 95% CI: 1.17–1.83 for incident HF; p for trend 0.039) illustrated in a Kaplan-Meier survival analysis (Figure 1). No interaction effect was seen for sex or smoking.
Conclusion
Low SELENOP levels are associated with a higher risk of incident HF supporting recent studies, which further emphasizes the need for randomly controlled trials to examine if supplementation with selenium improves prognosis.

Abstract
Abstract
Background
Globally, hypertension represents an enormous health issue as it is a major, yet modifiable risk factor for developing cardiovascular disease. Recently, chitinase-3-like protein 1 (CHI3L1) was shown to be positively associated with the incidence of hypertension among prehypertensive subjects, and variants of CHI3L1 gene were associated with both CHI3L1-levels and hypertension.
Purpose
To explore associations between prevalent hypertension and blood pressure, and 92 proteins with involvement in inflammation and cardiovascular disease.
Methods
Plasma samples from 1713 individuals from a Swedish population-based cohort (mean age 67.3±6.0 years; 28.9% women) were analysed with a proximity extension assay panel, consisting of 92 proteins. Prior to all analyses, subjects with prevalent cardiovascular disease, defined as having a history of prevalent coronary or stroke event, were excluded (n=189). Univariate logistic regression models were carried out exploring associations between each of the 92 proteins and prevalent hypertension, defined as systolic blood pressure ≥140 mmHg and/or a diastolic blood pressure ≥90 mmHg, or use of antihypertensive treatment (n=1168, 76.4%). Bonferroni-corrected significant associations between proteins and hypertension were further analysed using stepwise selection of covariates, namely age, body mass index, diabetes status, and cystatin C, in logistic regression models. Proteins with significant adjusted associations with prevalent hypertension were further analysed for associations with systolic and diastolic blood pressure individually in stepwise linear regression models. Complete data on all variables were available in 1527 subjects.
Results
Sixteen proteins were significantly associated with prevalent hypertension in univariate analyses. After adjustment, three proteins remained significantly associated with prevalent hypertension (i.e., CHI3L1, low-density lipoprotein receptor (LDL receptor) and tissue plasminogen activator (tPA); Table 1). In analyses of associations with systolic blood pressure, CHI3L1 and LDL receptor showed significant associations. In analyses of associations with diastolic blood pressure, CHI3L1, LDL receptor and tPA showed significant associations (Table 1).
Conclusions
Higher CHI3L1, tPA and LDL receptor levels were positively associated with prevalent hypertension after multivariable adjustment, among 1527 elderly subjects without established cardiovascular disease. Furthermore, higher CHI3L and LDL receptor levels were positively associated with mean systolic, as well as mean diastolic blood pressure in multivariable analyses.

Left ventricular kinetic energy across heart failure subgroups and subclinical diastolic dysfunction. Eur Heart J 2022.

Abstract
Abstract
Background
Diastolic dysfunction is a common finding in heart failure with preserved ejection fraction (HFpEF) and is considered a key mechanism for limiting exercise performance. Meanwhile, subclinical diastolic dysfunction (SDD) without heart failure is a growing concern and may be common in the general population [1,5[. The kinetic energy (KE) of intracardiac blood flow reflects the work spent on accelerating blood [3] and may provide a novel window into diastolic filling dynamics [2,4]. Our aim was therefore to quantify left ventricular KE in HFpEF patients and compare with healthy controls, subjects with SDD, and heart failure patients with moderately reduced (HFmrEF) or reduced ejection fraction (HFrEF).
Methods
We studied 12 healthy controls, 22 healthy subjects with 1–2 echocardiographic criteria of diastolic dysfunction (SDD), 16 HFpEF, 9 HFmrEF, and 16 HFrEF patients. All subjects underwent CMR imaging at 1.5T with acquisition of anatomical cines and 4D flow from a box covering the heart. The LV was delineated over the cardiac cycle and KE inside the segmentation calculated as 0.5 × m × v2, where v is the instantaneous velocity vector magnitude and m is blood mass. Group comparisons of peak and average values were performed using Kruskal-Wallis test with Dunn's uncorrected post hoc test. Significance was assigned at p<0.05. Median values are given.
Results
Groups were similar with regard to sex, blood pressure, and body surface area. HFpEF (median 72 years) and HFrEF patients (67 years) were significantly older than subjects with SDD (62 years, p=0.001). Examples of KE are shown in Fig. 1. Systolic peak and average KE did not differ between groups (p=0.81 and p=0.54 respectively, Fig. 2). Diastolic peak KE was higher in all groups of heart failure compared to controls (p<0.03 for all) and diastolic average KE was higher in HFmrEF and HFrEF compared to controls (p<0.02). The standard deviation for SDD was wider than in controls (1.6 mJ vs 0.8 mJ for systolic peaks, 2.7 mJ vs 1.1 mJ for diastolic peaks) and more closely resembled the HFpEF group (2.1 mJ in systole, 2.3 mJ in diastole).
Conclusions
Systolic kinetic energy expenditures are on average similar between controls, subjects with subclinical diastolic dysfunction, and heart failure patients, indicating that cardiac pumping involves approximately the same amount of systolic acceleration for a given afterload. Conversely, diastolic KE was found more dispersed both in heart failure and in asymptomatic individuals with subclinical diastolic dysfunction. Higher peak values of KE were seen in diastole for all types of heart failure including HFpEF, indicating more work is spent filling the ventricle. Measurements of KE in diastole could potentially be a new tool for assessment of heart failure, including early stages of disease development in some individuals with subclinical diastolic dysfunction.

Abstract
Background:In patients with the antiphospholipid syndrome (APS), concomitant systemic autoimmune rheumatic diseases (SARD) are common and often associated with more disease associated damage.Less is known about the prevalence of non-rheumatic autoimmune diseases (NRAID) in patients with APS.Objectives:To evaluate the incidence and prevalence of concomitant autoimmune diseases (AID) in a cohort of APS patients. The risk of AID was also evaluated with respect to the antiphospholipid antibodies (aPL) profiles.Methods:This retrospective cohort study comprises consecutive patients identified with APS through review of electronic medical records at Karolinska University Hospital, Sweden between 2014 and 2020. Exclusion criteria were misdiagnosis and age <18. Descriptive statistics was used for baseline data and multivariable Cox proportional hazard regression analysis to investigate the risk factors to develop new onset AID. Ethical approval was obtained from the Swedish Ethical Review Authority (2020-02333).Results:Of 271 included patients, 66% were women and the median age at diagnosis of APS was 43 years (IQR 31–55). At inclusion, 130 (48%) patients presented with other AID; 101 (37%) of them had a concomitant SARD while 54 (19%) had a NRAID. Systemic lupus erythematosus (SLE) was the most frequent in 30% of patients, followed by autoimmune thyroid disease (ATD) in 10% of patients.In addition, 35 (13%) APS-patients developed AID during the study period, corresponding to an incidence rate of 28.4 (95% CI; 19.3-40.3) per 1.000 person-years with mean time at risk of 4 (±2) years. Twenty-one (8%) patients developed a SARD and further 14 (5%) were diagnosed with a NRAID.The cumulative incidence for AID was significantly higher in patients with high titers of IgG aPL. Patients that developed SARD had significantly higher median titers of a-β2GPI IgG isotype, p=0.05. In the NRAID group, median a-β2GPI and aCL IgG isotypes were significantly increased, p=0.02 and p=0.04, respectively. The hazard ratio to develop diagnosis of AID was significantly increased in patients with high titers of the IgG isotype aPL (HR 2.4 95% CI; 1.1-5.3). Obstetric APS manifestations were associated with a significantly increased hazard ratio of 2.8 (95% CI; 1.1-7.7) to develop SARD, and also trendwise for AID, as a compound variable.During the study period, 52 patients had at least one new APS manifestation, as defined by the Sydney criteria (1). In comparison to patients without new manifestations, these patients had significantly higher median titers of aPL of the IgG isotype, and concomitant AID at first visit (p=0.01, p=0.02, respectively).Conclusion:APS patients are at high risk to develop other AID, and APS patients with concomitant AID had an increased risk to develop new clinical APS manifestations. These findings might be helpful when considering risk stratification and alternate treatment options in this patient group.References:[1]Miyakis S, Lockshin MD, Atsumi T et al.

Abstract
METHOD Associations between different biomarkers (proteomics, lipidomics, and metabolomics) coupled to either MHO or metabolically unhealthy obese (MUO) individuals were analyzed through principal component analysis (PCA). Subjects were identified from a subsample of 416 obese individuals, selected from the Malmö Diet and Cancer study-Cardiovascular arm (MDCS-CV, n = 3,443). They were further divided into MHO (n = 143) and MUO (n = 273) defined by a history of hospitalization, or not, at baseline inclusion, and nonobese subjects (NOC, n = 3,027). Two distinctive principle components (PL2, PP5) were discovered with a significant difference and thus further investigated through their main loadings. RESULTS MHO individuals had a more metabolically favorable lipid and glucose profile than MUO subjects, that is, lower levels of traditional blood glucose and triglycerides, as well as a trend of lower metabolically unfavorable lipid biomarkers. PL2 (lipidomics, p=0.02) showed stronger associations of triacylglycerides with MUO, whereas phospholipids correlated with MHO. PP5 (proteomics, p=0.01) included interleukin-1 receptor antagonist (IL-1ra) and leptin with positive relations to MUO and galanin that correlated positively to MHO. The group differences in metabolite profiles were to a large extent explained by factors included in the metabolic syndrome. CONCLUSION Compared to MUO individuals, corresponding MHO individuals present with a more favorable lipid metabolic profile, accompanied by a downregulation of potentially harmful proteomic biomarkers. This unique and extensive biomarker profiling presents novel data on potentially differentiating traits between these two obese phenotypes.

Abstract
Abstract
Background
Hemodynamic force analysis has been proposed as a noninvasive marker of cardiac function. In a recent study, longitudinal (apical-to-basal) hemodynamic forces were derived from anatomical MRI images and found decreased in heart failure with preserved ejection fraction (HFpEF) patients compared to controls, indicating a potential use for prognostication and testing of therapeutic response. This issue has not been investigated using the reference method of measurement.
Purpose
To investigate whether intraventricular hemodynamic forces computed using gold-standard cardiac magnetic resonance flow maps can reproducibly differentiate between healthy controls and HFpEF patients.
Methods
4D flow data were acquired in 59 subjects through cardiac magnetic resonance imaging using a 1.5T scanner (Siemens Healthcare, Erlangen, Germany). Hemodynamic forces within the LV were computed across the cardiac cycle using the Navier-Stokes equation to find the global pressure gradient, which was then integrated over the LV volume to produce the instantaneous hemodynamic force (unit: Newton) and subsequently normalized to ventricular volume, resulting in a force-volume index (N/l). Average longitudinal forces (root mean square, FRMS) were quantified over the entire cardiac cycle, with and without volume normalization.
Results
We studied 33 healthy subjects, 14 patients with HFpEF, 6 patients with HFmEF and 6 patients with HFrEF. Groups were similar with regards to sex, cardiac output, heart rate, systolic and diastolic blood pressure, and body surface area.
Volume-normalized FRMS did not differ between controls and HFpEF (0.86±0.19 vs. 0.75±0.19 N/l, p=0.08) while lower values were found in HFmEF (0.60±0.19 N/l, p=0.004) and HFrEF (0.38±0.15 N/l, p<0.0001) compared to controls (Figure 1A). There was a significant positive correlation between EF and FRMS, both for the entire population (R2 = 0.54, Figure 1B) and for patients (R2 = 0.67, p<0.0001 for both). Importantly, non-normalized FRMS did not differ between controls (Figure 1C, 0.10±0.03 N) and HFpEF (0.09±0.03 N, p=0.25), HFmEF (0.11±0.02 N, p=0.18) or HFrEF (0.09±0.02 N, p=0.67). Moreover, no correlation was seen between non-normalized FRMS and EF (Figure 1D).
Conclusions
Hemodynamic forces computed from reference standard 4D flow CMR data do not differentiate between healthy controls and HFpEF patients regardless of whether volume normalization is used or not. Our findings do not support a role for hemodynamic forces in HFpEF assessment.

Abstract
Abstract
Globally, many deaths and DALY:s are attributed to unhealthy diets. Short education, low income and migration are risk factors. Healthy food cost more and is less available while unhealthy food is cheaper and heavily advertised. Health guides (HG) speak Swedish and at least one more language and have networks among migrants. Their work draw on the Right to health framework - availability, accessibility, acceptability and quality for all (AAAQ). HG transfer viewpoints from their groups to health care and contribute to culturally accessible and acceptable information and support.
Public Health Unit of a local hospital initiated a project with the aim to develop a method to make information about healthy food accessible for a wider range of people. How to make food based dietary guidelines useful for recent migrants? How to avoid that official guidelines, when transferred by laymen, become distorted by personal experiences rather than being enriched by them? Systematic collection of viewpoints from inhabitants, helped of HG, implied that “shop walks” have potential to increase health equity. During a shop walk the guide shows healthy alternatives and transfers knowledge on different options. The intervention was developed during 2019. The first shop walks were conducted in February 2020.
Dietary guidelines were made useful by a process including cooperation between HG, nutritionally skilled staff and the communication department. A detailed manuscript and a participant folder were developed together with a mandatory education including theory and practice. 14 HG speaking six languages were included. During the first three weeks six shop walks were conducted. Qualitative evaluation implies that shop walks are functional arenas for strengthening AAAQ.
By structured shop walks HG can contribute to making dietary guidelines relevant for recent migrants. AAAQ is supported by participation of stakeholders in the population in collaboration with professional expertise.
Key messages
If food based dietary guidelines are to be made useful outside the majority population, methods that allow those most concerned to participate in planning, execution and evaluation should be used. Availability, accessibility, acceptability and quality - The Right to health framework – should be used when developing public health interventions that aim at health equity.

Abstract
Abstract
The Right to health framework supports available, accessible and acceptable health care of high quality for all (AAAQ). Health of migrants often worsen in the new country. AAAQ may be hindered by poverty, discrimination, health cares' shortcomings and misunderstandings, respectively. Advocating for marginalised groups' Right to health include action. Interventions based on shared influence, participation and control need to be launched. Cultural mediators (CM), i.e. persons that are knowledgeable in both cultures and with networks in migrant groups help overcome lingual problems, lack of trust and uneven power relations. This resource needs to be further examined.
How can a CM strengthen AAAQ in a public health setting? Women with Somalian origin living in an underserved neighborhood in Sweden contacted the Public Health Unit of a local hospital, asking for support for a health focused group-activity. Weight loss after delivery was a primary concern. Women gathered monthly 2018-19. The objective was to support healthy life style habits drawing on issues raised by the women. The intervention was conducted by group talks, led by the CM and a public health planner. Methods were based on Social Cognitive Theory focusing on self-efficacy.
The CM recruited women, helped them to find the venue, encouraged them to trust the public health planner and broadened perspectives to include female genital mutilation, children's food, how to seek care and workforce issues. Trust developed over time. 70 women participated. Reported gains were raised awareness of ones' rights, increased self-efficacy in relation to food, physical activity and how to support children to a healthy life style. Support for a healthy lifestyle was made more available, accessible and acceptable by the cooperation with the CM, as was the quality of the support.
A CM bridges distances regarding spoken language, trust and cultural understanding. S/he puts forward perspectives and needs from the group in question
Key messages
The Right to health framework highlights areas that need to be in focus when advocating for health equity. Health care workers in settings with many migrants should strive to include cultural mediators in planning, execution and evaluation of interventions.

Abstract
Abstract
Health inequity is a global concern. The Public Health Unit (PHU) of a local hospital conducts activities in partnership with many actors, aiming at decreasing the health gap. This commission highlights the need to advocate for shared participation, influence and control and for methods that make health care available, accessible and acceptable for all. A platform for such advocacy includes analysis of interventions based on evidence-informed strategies.
How may PHU:s activities (2019) have contributed to health equity? Analyses build on documentation in the Health Equilibrium Methodology system which draw on Social Cognitive Theory, critical reflection and quantitative measurements.
PHU participated in 81 meetings on the strategic level. Common values and trust, more stable in long-term partnership, facilitated development of population-focused activities that could support marginalised groups. On the population level the Unit participated in 170 activities. Examples were bicycle courses, family centred talks with dietician, tobacco talks with youths and groups for mothers of Somalian origin. Common strategies were to support self-efficacy by confirming and communicating knowledge, to use reciprocal determination by drawing attention to environmental factors, to affect outcome expectations by highlighting links between lifestyle and health and to facilitate healthy habits by making guidelines accessible. Critical reflection highlighted barriers for making use of general advice. Data indicate that professional reflection is needed to implement shared participation, influence and control and that trust-building is dependent on stable presence.
Professional reflection, systematically documented and taken into account is needed to fully use health care potential to ensure Right to health for all.
Trust takes time to build but creates possibilities for inhabitants to raise health issues from their perspective, enabling meaningful support
Key messages
To take the full potential of public health work into account actors should use systematic documentation focusing on processes, avoiding to reduce evaluation to numerical reports. Health care professionals that aim at closing the health gap need to distance themselves from their personal perspectives by using systematic critical reflection of their practice.

Comparison of quality of urinary bladder filling in CT urography with different doses of furosemide in the work-up of patients with macroscopic hematuria. Radiography (Lond) 2020; 27:136-141. [PMID: 32727709 DOI: 10.1016/j.radi.2020.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 07/02/2020] [Accepted: 07/03/2020] [Indexed: 11/30/2022]
Abstract
INTRODUCTION The protocol for preparation of computed tomography urography (CTU) examinations at our hospital was changed in 2013 to improve the quality of urinary bladder filling in the excretory phase. The aim of this study was to evaluate the quality of urinary bladder filling on CTU after different doses of furosemide were administered to patients with macroscopic hematuria. METHODS The cohort was 215 patients who underwent elective CTU due to macroscopic hematuria between 2014 and 2018. 5 mg furosemide were administrated to 100 patients, 2.5 mg to 100 patients and 0 mg to 15 patients. Contrast medium layered bladders were excluded, leaving 193 patients: 92, 89 and 12 in each group. Urinary bladder volume was calculated in corticomedullary (CMP) and excretory phase (EP). Bladder distension was classified as satisfactory or not. Attenuation of bladder content in EP was noted. RESULTS Average volume in EP was 370 ± 224 ml (28-1052) after 5 mg furosemide, 274 ± 120 ml (43-628) after 2.5 mg and 180 ± 104 ml (53-351) after 0 mg. 85% of the bladders were satisfactory distended after 5 mg, 80% after 2.5 mg and 58% after 0 mg. Average attenuation was 266 ± 89 HU (103-524) after 5 mg, 362 ± 156 HU (118-948) after 2.5 mg and 761 ± 331 HU (347-1206) after 0 mg. The differences in volume and attenuation were significant. CONCLUSION 5 mg furosemide is preferred rather than 2.5 mg in preparation for CTU examinations of patients with macroscopic hematuria. There was no difference between the doses concerning rate of satisfactory bladder distension, but the higher dose resulted in larger bladder volume and more suitable attenuation of bladder content. IMPLICATIONS FOR PRACTICE Development of CTU-image quality could improve bladder cancer diagnostics.

Abstract
Aim: The aim of the study was to analyse the impact of delivery on breastfeeding at 6 months, with special focus on caesarean section combined with established breastfeeding at 2 months. Methods: Delivery mode and breastfeeding at 2 and 6 months were studied in a database of 130,993 infants from two Swedish counties between 1990-2011. Results: The difference in breastfeeding rates at 6 months between children delivered by caesarean section and children delivered vaginally was smaller in a subpopulation of children with established breastfeeding at 2 months compared to all children. The impact of delivery method on breastfeeding at 6 months was independent of child gender, mother's first child, maternal smoking and maternal education. Conclusions: Breastfeeding in mothers giving birth by caesarean section is more likely to continue until (at least) 6 months if established early (at 2 months). It may be worthwhile to promote breastfeeding for mothers who deliver by caesarean section.

Abstract
Midregional Pro-enkephalin A (MR-PENK A) and N-terminal Protachykinin A (NT-PTA) have been associated with vascular dementia. However, the longitudinal relationship between these biomarkers and incident dementia has not been fully investigated. In the population-based Malmö Preventive Project, circulating levels of MR-PENK A and NT-PTA were determined in a random sample of 5,323 study participants (mean age: 69 ± 6 years) who were followed-up over a period of 4.6 ± 1.6 years. The study sample included 369 patients (7%) who were diagnosed in the same period with dementia. We analyzed relationship of MR-PENK A and NT-PTA with the risk of developing dementia by using multivariable-adjusted Cox regression models adjusted for traditional risk factors. Increased plasma levels of MR-PENK A were associated with higher risk of incident vascular dementia whereas no associations were found with all-cause or Alzheimer dementia. The risk of vascular dementia was mainly conferred by the highest quartile of MR-PENK as compared with lower quartiles. Elevated levels of NT-PTA yielded significant association with all-cause dementia or dementia subtypes. Elevated plasma concentration of MR-PENK A independently predicts vascular dementia in the general population. MR-PENK A may be used as an additional tool for identifying vascular subtype in ambiguous dementia cases.

Abstract
Abstract
Background
For an intervention to contribute to decreased health gaps, people living in underserved areas must participate in the research-to-action process during the development of the intervention.
Methods for increased engagement and participation have been developed within the community-based participatory research (CBPR) paradigm. Group Level Assessment (GLA) is a qualitative, participatory methodology that is designed for a large group to generate and evaluate relevant needs and priorities within a lens of action for positive social change. Influence of researchers is tuned down in favour of partnership and impact from the community. Ideally, the process results in participant-driven data and relevant action plans. The aim was to apply GLA to generate reflections on the situation in the community, aligning towards action for change.
Methods
We applied GLA together with people living in Gårdsten, an underserved Swedish suburb where obesity, caries and other illnesses are prevalent. Residents were recruited by posters and post cards at a community center and by snowball sampling. In total, 47 residents attended at least one of eight GLA sessions held over a five-month time period. The majority were women. Outcomes were reflections, suggestions and actions for change.
Results
Themes were: resident pride of the area, the importance of communication and of places to meet, a feeling of being abandoned by society, and a desire for more collaboration between schools and parents. Immediate results were a language café and inquiries from the community about information regarding teeth, food and health. When the results were presented for stakeholders in a report and an exhibition, new collaborations were founded and old were refreshed.
Conclusions
GLA helped residents identify what they thought valuable and relevant concerning health issues and supported them in taking actions to achieve change.
Key messages
Participatory processes that directly engage community residents can result in fruitful discussions and actions. Methodologies like GLA that support such processes may contribute to closing the health gap.

Abstract
Abstract
Problem
Angered Hospital is situated in the northeast of Gothenburg, Sweden, serving municipalities with high prevalence of ill health. Dedicated to increase health equity, the hospital has established a Public Health Unit (PHU) to support residents to healthier lives. PHU found that lack of transparency concerning strategies, reflections and results hindered knowledge-exchange between public health practitioners. Also, information from the execution of public health interventions and programs needed to be more accessible for policy-makers and researchers.
Description
PHU developed a digitalized methodology for systematic steering. It draws on control, influence and participation, using Social Cognitive Theory to plan for strategies. The evaluation build on norm-critical reflections of structured reports. Themes include: How to improve efforts on the structural level? What measures do we plan for and conduct to enhance participation from residents? Quantitative goals were set.
Results
222 activity reports were launched and discussed by team members, leading to professional development. Strategies to support self-efficacy were used throughout. The strategy “reciprocal determinism” was planned for more than used, due to giving floor to participants to raise their issues. Methods that draw on transparency, sound evidence and continous collaboration allow for residents to rethink their lifestyle and strive for change. Issues for future development included the importance og giving time for trust and shared values to emerge. Quantitive goals were reached.
Lessons
Quality assurance of public health work enables formative and summative evaluation, increases potential to close the health gap, provides policy-makers with valuable knowledge and opens for research. Trust and shared values are vital at all levels. The methodology allows for organizations to develop their health literacy in order to include and give voice to people in underserved areas.
Key messages
Public health units aiming at health equity should use tailored evidence based methods, including norm-critical reflections. Digitalizing a methodological instrument increases accessability and transparency which enables common knowledge development.

Abstract
Abstract
HEM draws on theories for health behavior and power relations. The methodology contains a structured documentation for formative and summative purposes. Strive for a high level of participation, control and influence from individuals and community members is a foundation pillar. Systematic use of theories allows for answering the fundamental question “in what way do we anticipate the planned intervention to contribute to closing the health gap?” Social Cognitive Theory (SCT) considers social and physical environment. HEM currently involve several SCT determinants in planning and evaluation; self- efficacy, observational learning, facilitating, expectations of outcome, reciprocal determination. The qualitative procedure is described below. Numeric data are also collected.
Step one (before action, e.g. a dialogue-meeting): Consider which determinant(s) may be affected by the planned action, and by what mechanisms.
Step two: Carry out the action.
Step three: Describe what happened, based on input from the participants and the anticipated determinants and mechanisms.
Step four: Systematic self-critical review based on common grounds for discrimination. Examples: Was it difficult to engage or include participants because of language, gender, function variation, national background or other factor? In retrospect, can you identify stereotypes in the examples you used? Did anybody else at the event act to maintain prejudice or exclusion?
Step five: consider implications for methodological development.
Step six: Formative collective evaluation based on reflections from step four and implications from step five.
Stakeholders using HEM gather regularly for workshops based on their HEM-reports, aiming at developing tools for increasing health equity. HEM is implemented in public health work of Angered Hospital and the Dental Public Health, Region Västra Götaland, and is used by 20 different stakeholders. A web-application has been developed to facilitate documentation and spread.

Abstract
Abstract
The aim was to, in an oral health promoting setting in low socioeconomic areas, implement a method aiming at improving quality of work by assessing both formative and summative results. The overall aim is to decrease health inequity.
Methods
Five teams of dental hygienists (n = 5) and dental nurses (n = 3), who operated in socioeconomic low-status areas, participated. The teams were performing health promoting activities on arenas as for example family-centrals. These teams were introduced on how to report health promoting activities according to the Health Equilibrium Methodology (HEM), which is based on Social Cognitive Theory. Following questions were put and answered in every report: Which health determinants were targeted? Did any person seem to perceive him-/herself excluded? Did anything unexpected happen? What to think about next time? Quantitative data were also documented: Almost six-hundred individuals were included in a total of 36 reports. Of these 50% were adults/parents and the rest children, most of them between 1-6 years old. The reports were written directly into a database after every activity and then processed by a facilitator and later discussed with the teams in workshops every third month.
Results
Analysis of the reports shows that the implementation of health promoting activities according to HEM included the following: -Identification of important health determinants. - Attention on how to get everyone involved and if anything unexpected happened. - Suggestions for change for the next time. Throughout the workshops the team-members exchanged experiences.
Conclusions
The HEM-method facilitates depicting and discussing the process of health promotion with focus on health equity. Thereby the method has a potential to support development of high-quality health-promoting activities in populations with low socioeconomic status. It may also lead to a better professional self-confidence.

Abstract
Abstract
Issue
At the center of the concept “Health” is self efficacy. Communication has potential to increase or decrease individuals/groups conception of themselves as valuable beings. In communities haunted by territorial stigmatization this aspect is crucial. Respectful communication, building on a true belief that competencies and resources dwell in every human being, evoke trust which is an important aspect of public health. Angered Hospital is situated in an area with high prevalence of illness. To allow for residents to exert influence over interventions and programs, the Public Health Unit of the hospital need access to skills not only in the area of public health but also in communication design.
Description of the problem
The aim was to develop a trusting cooperation between the Public Health and Communication Units in a hospital, building on adherence to the Declaration on Human Rights and on expert knowledge. Focus is on increased health equity. Given barriers of spoken language and different perspectives, how can we set the scene for merging lay and expert knowledge on conditions for healthy habits and prerequisites for change, on individual and structural levels? How can residents be encouraged to seek help when needed? During two years, collaboration developed by intertwining theory and practice in continous discussions on planned and produced objects. Knowledge in communication design and in determinants of health equity, respectively, enriched both parties.
Changes
A trusting relationship developed, resulting in the objects “Heroes of Awngaryd”. The Heroes appear in many contexts; transfering knowledge, encouraging residents to use their competencies, inviting them to participate, and guiding to adequate care.
Lessons
Sharing of the vision of health equity, active embracing of the Declaration of Human Rights and mutual respect for each others expert knowledge form the base for a successful and transparent cooperation between Public Health and Communication.
Key messages
In this setting, expert knowledge in both communication design and public health are needed to contribute to increased health equity. Common values, trust and specific skills optimize the work.

Abstract
Abstract
Socioeconomic position, expressed in terms like educational level, income, wealth or origin, is a strong predictor of most health outcomes. Sustainable efforts for good and equitable health need to draw on theories that consider power relations as well as scientific methods for health promotion, prevention and /or treatment. Systematic planning and documentation is required. The perspective should include not only life style habits but also issues like discrimination and stigmatization. Control and influence from participants are necessary to assure that goal-setting and measures taken are adequate.
Health inequity emerges from structural issues and is mediated by mechanisms on different levels, mechanisms of which some are difficult to describe and analyze. Regrettably, health care systems, including public health interventions, in many cases reinforce this inequity. Health care staff’s personal perspectives and prerequisites (e.g regarding education and income) often differ from the corresponding ones in groups with the less favorable health outcomes. That is one reason why efforts for equitable health need to involve perspectives, prerequisites and health motives of “targeted” individuals and groups as salient parts of interventions, from the planning stage and throughout. A complementary way to prevent intervention procedures from consolidating current positions of power is to allow for professionals to continuously perform critical reflection of their own presuppositions and prejudices in relation to actions and results.
The use of determinants from Social Cognitive Theory (SCT) (self- efficacy, observational learning, facilitating, expectations of outcome, reciprocal determination) enables planning that consider not only individuals and groups but also their social context. Systematic use of strategies from SCT, critical reflection and formative as well as summative evaluations allow for quality assurance and knowledge development.

Abstract
Abstract
Introduction
The evolving use of multiplex proteomic platforms provides an excellent tool for investigating associations between multiple proteins and subclinical atherosclerotic disease. In this study, we evaluated the impact of a multiplex protein panel, on carotid intima-media thickness (cIMT) as a marker of subclinical atherosclerosis.
Purpose
We used a multiplex proteomic platform to identify possible associations between proteins and subclinical carotid atherosclerosis as measured by carotid ultrasound in an African population.
Methods
In the Sympathetic Activity and Ambulatory Blood Pressure in Africans (SABPA) study, 92 proteins from the Proseek Multiplex CVD III 96×96 (Olink Bioscience, Sweden) were analyzed in 378 participants (mean age 44.7±9.6 years, 50.6% women, 10.8% with known cardiovascular disease). Carotid ultrasound was performed for measurements of the carotid intima-media thickness (cIMT, mean 0.663±0.127 mm) and calculation of cross-sectional wall area (CSWA, mean 13.5±4.4mm2), a measure of target organ damage. Possible associations between the proteins, and cIMT and CSWA, respectively, were explored using linear regression models. A two-sided Bonferroni corrected P-value of 0.05/92=5.4x10–4 was considered statistically significant in the crude analysis.
Results
Of 18 proteins (1 standard deviation of change of ln-transformed values) that were Bonferroni-corrected (p≤5.4x10–4) significantly associated with cIMT and/or CWAS in crude analyses, the following remained significant after further adjustment for age, sex, waist circumference, systolic blood pressure, smoking and total cholesterol: growth-differentiation factor-15 (GDF15; β 0.017, p=0.050), E-selectin (SELE; β 0.019, p=0.017), carboxypeptidase A1 (CPA1; β 0.019, p=0.019), C-C motif chemokine 15 (CCL15; β 0.031, p<0.001), chitinase-3-like protein 1 (CHI3L1; β 0.021, p=0.007), the hemoglobin scavenger receptor (CD163; β 0.021, p=0.008) and osteoprotegerin (OPG; β 0.022, p=0.004). As for target-organ damage defined by CSWA, SELE (β 0.459, p=0.018), CCL15 (β 0.398; p=0.032) and CD163 (β 0.541, p=0.005) showed multivariate adjusted significant associations.
Conclusion
In an African population, we could confirm five proteins (GDF15, SELE, CHI3L1, CD163 and OPG) associated with cIMT, but in addition identified two proteins (CPA1 and CCL15) with novel associations with cIMT and/or CSWA.

Abstract
Abstract
Introduction
Cerebral side effects have long been recognized as complications to beta-blocker treatment. However, evidence of a longitudinal relationship between the use of beta-blockers and incident dementiais still controversial.
Objective
To evaluate the longitudinal relationship between use of beta-blockers, as a class, and incident risk of all-cause dementia, vascular dementia, Alzheimer and mixed dementia.
Methods
From the prospective, population-based, Malmö Preventive Project, 18,063 individuals (mean age 68.2, males 63.4%) were included at baseline and followed for 84,506 person-years. Patients with prevalent cerebrovascular disease and dementia were excluded. In order to weight the risk of incident dementia associated with beta-blocker consumption, we performed propensity score matching analysis, resulting in 3,720 matched pairs of beta-blocker users and non-users at baseline, and multivariable Cox proportional-hazardsregression.
Results
Overall, 122 study participants (1.6%) were diagnosed with dementia over the course of follow-up. Use of beta-blockers was independently associated with increased risk of developing vascular dementia, regardless of confounding factors (HR: 1.72, 95% CI 1.01–3.78; p=0.048). Conversely, treatment with BB was not associated with increased risk of all-cause, Alzheimer and mixed dementia (HR: 1.15; 95% CI 0.80–1.66; p=0.44; HR: 0.85; 95% CI 0.48–1.54; P=0.59 and HR: 1.35; 95% CI 0.56–3.27; p=0.50, respectively).
Conclusions and relevance
We observed that use of beta-blockers, as a class, is associated with increased longitudinal risk of vascular dementia in the general elderly population, regardless of cardiovascular risk factors, prevalent or incident history of atrial fibrillation, stroke, coronary events and heart failure. Further studies are needed to confirm our findings in the general population and to explore the mechanisms underlying the relationship between use of beta-blockers and increased risk of vascular dementia.

Abstract
Abstract
Background
Although Azurocidin-1 (Azu-1), also known as heparin binding protein, has been associated with myocardial infarction, possible associations of Azu-1 with congestive heart failure (CHF) remains unknown. Here we tested the possible association of Azu-1 with prevalent diastolic dysfunction and/or incident CHF in a large Swedish prospective population based cohort.
Methods
Azu-1 was analyzed using the Proseek Multiplex CVD III panel in 1737 participants from a subsample of the population (mean age 67 years, 29% women) who underwent a complete echocardiographic examination. All biomarkers were logarithmized and standardized prior to statistical analysis.
Logistic and linear regression were adjusted for age, sex, BMI, diabetes, systolic and diastolic blood, anti-hypertensive treatment and subjects with an ejection fraction below 50% were excluded for the analysis of prevalent diastolic dysfunction and Azu-1. For the linear regression model, we used E/é ratio as a key functional variable in assessing diastolic function according to ESC 2016 Guidelines for Acute and Chronic Heart Failure. Furthermore, we dichotomized the E/é ratio at >13 in another logistic regression model. Finally, in line with ESC Guidelines 2016, we combined the key functional (E/é >13) and key structural (left ventricular mass index (LVMI) ≥115 g/m2 for males and ≥95 g/m2 for females) alterations for diastolic dysfunction and used this variable in both logistic regression for association with Azu-1 and for Cox regression analysis of incident CHF. 1439 subjects (938 cases with some degree of diastolic dysfunction and 501 controls) remained for the analysis.
For the analysis of incident CHF, Cox regression was used excluding subjects with ejection fraction below 50% and prevalent CHF and further adjusted for prevalent coronary disease on top of age, sex, BMI, diabetes, systolic and diastolic blood and anti-hypertensive treatment. 1,511 subjects (64 incident cases of CHF vs 1447 controls; median follow up time 8.9 years) remained.
Results
After adjustment for above mentioned risk factors, each 1 standard deviation (SD) of increase in Azu-1 was associated with any degree of prevalent diastolic dysfunction (odds ratio (OR) 1.13, p=0.048), E/é >13 OR 1.21, p=0.028 and for combined LVMI and E/é OR 1.17, p=0.015. In fully adjusted linear regression Azu-1 was associated with E/é with a β-coefficient of 0.056, p=0.018.
In a fully adjusted Cox regression models Azu-1 was associated with incident CHF (hazard ratio (HR) 1.32, p=0.025). As expected and as proof of concept E/é >13 and combined LVMI with E/é were also associated with incident CHF; HR 2.84, p<0.001 and HR 2.12, p=0.006, respectively.
Conclusion
An inflammatory mediator, Azurocidin-1, is associated with prevalent diastolic dysfunction, E/é, E/é combined with LVMI as well as incident congestive heart failure in a population-based cohort.

Abstract
Background/Aims
Metabolically healthy obesity (MHO) is a controversial topic, since the underlying mechanisms and contributing factors behind this phenotype remain unclear. Here we aimed to investigate the characteristics of MHO, as well as prospective mortality risk.
Method
A cross-sectional analysis was carried out in a subsample of 3,812 obese subjects (BMI ≥30 kg/m2) selected from the Malmo Diet Cancer Study (MDCS) cohort (n=28,403). Subjects with MHO (n=1182; mean age 58±7 years) were defined by having no records of hospitalization in the national Swedish Hospital Discharge Register prior to the baseline examination, other than hospitalization due to normal deliveries or external injuries. MHO subjects were further compared to subjects with metabolically unhealthy obesity, MUO (n=2,630; mean age 60±7 years), and all non-obese individuals (n=24,591; mean age 58±8 years) in the cohort study. Moreover, prospective risk analyses for incident morbidity and mortality were carried out by Cox regression.
Results
Compared to MOU individuals (one-way ANOVA), MHO individuals were younger (58±7 years vs. 60±7 years, p=0.001) and more likely to be male (41.2% vs 37.1%, p=0.016). MHO individuals reported a significantly lower proportion of sedentary life style than MUO (17.4% vs. 21.9%, p=0.009), and were more likely to hold a university degree (13.4% vs. 9.4%, p=0.003). Furthermore, MHO individuals had significantly lower HbA1c (p=0.012), fasting plasma glucose (p=0.001) and triglyceride levels (p=0.011) as compared to their MOU counterparts. Cox-regression analysis adjusted for age, sex, smoking and blood pressure (follow-up time 20±6 years) showed both a significantly lower all-cause mortality risk for MHO individuals as compared to MUO (HR 0.74, 95% CI: 0.66–0.82; p=0.001), as well as lower total incident cardiovascular (CV) morbidity risk (HR 0.69, 95% CI: 0.60–0.80; p=0.001). Interestingly, when comparing MHO individuals to all non-obese individuals in the MDCS, there were no significant differences in neither mortality risk (p=0.9), nor incident CV morbidity risk (p=0.7).
All-cause mortality risk
Conclusion
Compared to MUO individuals, MHO individuals presented with a higher level of education- and physical activity together with a more favorable lipid- and glucose profile. MHO individuals were at significantly lower prospective risk of total- and cardiovascular mortality during 20-years follow-up, as compared to MOU individuals. Notably, no significant differences could be seen in mortality and CV morbidity risks when comparing MHO subjects to all non-obese individuals in the total cohort.

Monitoring of cerebral oximetry during head-up tilt test in adults with history of syncope and orthostatic intolerance. Europace 2019; 20:1535-1542. [PMID: 29036615 DOI: 10.1093/europace/eux298] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2017] [Accepted: 08/31/2017] [Indexed: 11/14/2022] Open
Abstract
Aims We applied near-infrared-spectroscopy (NIRS) to measure absolute frontal cerebral tissue oxygen saturation (SctO2) during head-up tilt test (HUT) in patients investigated for unexplained syncope. Methods and results Synchronized non-invasive beat-to-beat haemodynamic monitoring, ECG, SctO2 (NIRS; normal range: 60-80%), and peripheral oxygen saturation (left hand, SpO2) were applied during HUT in a random sample of patients with unexplained syncope. Tracings of 54 patients (mean-age: 55 ± 19 years, 39% male) with negative HUT, vasovagal syncope (VVS), or orthostatic hypotension (OH) were analysed. In 44 patients HUT was diagnostic, in 10 HUT was negative. Thirty-one experienced VVS. Of these, 6 had spontaneous and 25 nitroglycerin-induced syncope. Thirteen patients had orthostatic hypotension (OH). Although there was no significant change in mean-arterial pressure from baseline to 1 min before syncope or end of passive HUT phase (-1.4 ± 13.9 mmHg; P = 0.45), there was a significant fall in SctO2 during the same period (-3.2 ± 3.2%; P ≤ 0.001). Among patients who experienced syncope, a decrease in SctO2 from 71 ± 5% at baseline to 53 ± 9% (P < 0.001) at syncope was observed. During HUT, there was a significant difference in delta SctO2 between spontaneous VVS (-4.5 ± 3.0%) and negative HUT (-1.3 ± 1.9%; P = 0.021), but not between spontaneous VVS and OH (-5.4 ± 4.2%; P = 0.65). In spontaneous VVS, progressive decrease of SctO2 was independent of mean arterial pressure decrease (P = 0.22). Conclusions Progressive decrease in cerebral tissue oxygenation independent of mean-arterial pressure may precede spontaneous vasovagal reflex during tilt. Patients experience syncope when SctO2 falls below 60%. These data confirm clinical utility of absolute cerebral oximetry monitoring for syncope investigation. We applied NIRS to measure frontal cerebral tissue oxygen saturation (SctO2) during head-up tilt test (HUT) in patients with unexplained syncope. In 44 of 54 patients, HUT was diagnostic. In patients with syncope, a significant SctO2-decrease was observed. Different patterns of SctO2 can be detected.

Abstract
BACKGROUND Cerebral endothelial dysfunction occurs in a spectrum of neurodegenerative diseases. Whether biomarkers of microvascular endothelial dysfunction can predict dementia is largely unknown. We explored the longitudinal association of midregional pro-atrial natriuretic peptide (MR-proANP), C-terminal endothelin-1 (CT-proET-1) and midregional proadrenomedullin (MR-proADM) with dementia and subtypes amongst community-dwelling older adults. METHODS A population-based cohort of 5347 individuals (men, 70%; age, 69 ± 6 years) without prevalent dementia provided plasma for determination of MR-proANP, CT-proET-1 and MR-proADM. Three-hundred-and-seventy-three patients (7%) were diagnosed with dementia (120 Alzheimer's disease, 83 vascular, 102 mixed, and 68 other aetiology) over a period of 4.6 ± 1.3 years. Relations between baseline biomarker plasma concentrations and incident dementia were assessed using multivariable Cox regression analysis. RESULTS Higher levels of MR-proANP were significantly associated with increased risk of all-cause and vascular dementia (hazard ratio [HR] per 1 SD: 1.20, 95% confidence interval [CI], 1.07-1.36; P = 0.002, and 1.52; 1.21-1.89; P < 0.001, respectively). Risk of all-cause dementia increased across the quartiles of MR-proANP (p for linear trend = 0.004; Q4, 145-1681 pmol L-1 vs. Q1, 22-77 pmol L-1 : HR: 1.83; 95%CI: 1.23-2.71) and was most pronounced for vascular type (p for linear trend = 0.005: HR: 2.71; 95%CI: 1.14-6.46). Moreover, the two highest quartiles of CT-proET-1 predicted vascular dementia with a cut-off value at 68 pmol L-1 (Q3-Q4, 68-432 pmol L-1 vs. Q1-Q2,4-68 pmol L-1 ; HR: 1.94; 95%CI: 1.12-3.36). Elevated levels of MR-proADM indicated no increased risk of developing dementia after adjustment for traditional risk factors. CONCLUSIONS Elevated plasma concentration of MR-proANP is an independent predictor of all-cause and vascular dementia. Pronounced increase in CT-proET-1 indicates higher risk of vascular dementia.

Abstract
AIM To study a potential link between breastfeeding in infancy and obesity at age 4. MATERIALS AND METHODS A total of 30,508 infants born during 2002-2007 from the databases of the Preventive Child Health Services in two Swedish counties and from national registers were studied. The outcome variable was obesity at age 4. Analyses were conducted by logistic regression models using the methodology of generalized estimating equations. Analyses were adjusted for child sex and maternal anthropometric and sociodemographic variables. RESULTS In unadjusted analyses, any breastfeeding up to 9 months was linked to successively decreasing odds ratios (ORs) for obesity at age 4 (ORs 0.78-0.33), however, not significantly for 1 week and 2 months of breastfeeding. In adjusted analyses, the same pattern remained statistically significant for breastfeeding for 4 (OR 0.51), 6 (OR 0.55), and 9 (OR 0.47) months. Child sex, maternal education, maternal body mass index, and maternal smoking additionally influenced child obesity. CONCLUSION Breastfeeding duration for at least 4 months may contribute independently to a reduced risk for childhood obesity at 4 years.

Abstract
Essentials Stimulating endogenous fibrinolysis could be a novel antithrombotic strategy. The effect of valproic acid on endothelial tissue plasminogen activator in mice was investigated. Valproic acid increased tissue plasminogen activator expression in vascular endothelium. Valproic acid reduced fibrin deposition and thrombus formation after vascular injury. SUMMARY Background The endogenous fibrinolytic system has rarely been considered as a target to prevent thrombotic disease. Tissue-type plasminogen activator (t-PA) production is potently increased by histone deacetylase (HDAC) inhibitors in endothelial cells in vitro, but whether this translates into increased vascular t-PA production and an enhanced fibrinolytic capacity in vivo is unknown. Objectives To determine whether the HDAC inhibitor valproic acid (VPA) stimulates production of t-PA in the vasculature of mice, and whether VPA pretreatment affects fibrin deposition and clot formation after mechanical vessel injury. Methods Mice were injected with VPA twice daily for up to 5 days. t-PA mRNA, and antigen expression in the mouse aorta and the circulating levels of t-PA were determined. Fibrin and thrombus dynamics after mechanical vessel injury were monitored with intravital confocal microscopy. Potential effects of VPA on platelets and coagulation were investigated. Results and Conclusions We found that VPA treatment increased vascular t-PA production in vivo and, importantly, that VPA administration was associated with reduced fibrin accumulation and smaller thrombi in response to vascular injury, but still was not associated with an increased risk of bleeding. Furthermore, we observed that higher concentrations of VPA were required to stimulate t-PA production in the brain than in the vasculature. Thus, this study shows that VPA can be dosed to selectively manipulate the fibrinolytic system in the vascular compartment and reduce thrombus formation in vivo.

Abstract
Advanced model-based iterative reconstruction algorithms in quantitative computed tomography (CT) perform automatic segmentation of tissues to estimate material properties of the imaged object. Compared with conventional methods, these algorithms may improve quality of reconstructed images and accuracy of radiation treatment planning. Automatic segmentation of tissues is, however, a difficult task. The aim of this work was to develop and evaluate an algorithm that automatically segments tissues in CT images of the male pelvis. The newly developed algorithm (MK2014) combines histogram matching, thresholding, region growing, deformable model and atlas-based registration techniques for the segmentation of bones, adipose tissue, prostate and muscles in CT images. Visual inspection of segmented images showed that the algorithm performed well for the five analysed images. The tissues were identified and outlined with accuracy sufficient for the dual-energy iterative reconstruction algorithm whose aim is to improve the accuracy of radiation treatment planning in brachytherapy of the prostate.

Abstract
New paradigms for parallel programming have been devised to simplify software development on multi-core processors and many-core graphical processing units (GPU). Despite their obvious benefits, the parallelisation of existing computer programs is not an easy task. In this work, the use of the Open Multiprocessing (OpenMP) and Open Computing Language (OpenCL) frameworks is considered for the parallelisation of the model-based iterative reconstruction algorithm DIRA with the aim to significantly shorten the code's execution time. Selected routines were parallelised using OpenMP and OpenCL libraries; some routines were converted from MATLAB to C and optimised. Parallelisation of the code with the OpenMP was easy and resulted in an overall speedup of 15 on a 16-core computer. Parallelisation with OpenCL was more difficult owing to differences between the central processing unit and GPU architectures. The resulting speedup was substantially lower than the theoretical peak performance of the GPU; the cause was explained.

Abstract
OBJECTIVE The objective was to evaluate a manualized theory-driven primary preventive intervention aimed at early childhood obesity. The intervention was embedded in Swedish child health services, starting when eligible children were 9 to 10 months of age and continuing until the children reached age 4. METHODS Child health care centers in 8 Swedish counties were randomized into intervention and control units and included 1355 families with 1369 infants. Over ∼39 months, families in the intervention group participated in 1 group session and 8 individual sessions with a nurse trained in motivational interviewing, focusing on healthy food habits and physical activity. Families in the control group received care as usual. Primary outcomes were children's BMI, overweight prevalence, and waist circumference at age 4. Secondary outcomes were children's and mothers' food and physical activity habits and mothers' anthropometrics. Effects were assessed in linear and log-binominal regression models using generalized estimating equations. RESULTS There were no statistically significant differences in children's BMI (β = -0.11, 95% confidence interval [CI]: -0.31 to 0.08), waist circumference (β = -0.48, 95% CI: -0.99 to 0.04), and prevalence of overweight (relative risk = 0.95, 95% CI: 0.69 to 1.32). No significant intervention effects were observed in mothers' anthropometric data or regarding mothers' and children's physical activity habits. There was a small intervention effect in terms of healthier food habits among children and mothers. CONCLUSIONS There were no significant group differences in children's and mothers' anthropometric data and physical activity habits. There was, however, some evidence suggesting healthier food habits, but this should be interpreted with caution.

Abstract
AIM To study potential socioeconomic differences within the general decline in breastfeeding over time. METHODS Data was collected for 51 415 infants born 2004-2010 from the databases of statistics of the Preventive Child Health Care Services in Uppsala and Orebro counties in Sweden and socioeconomic indicators from Swedish national registers. Breastfeeding data (breastfed/not breastfed) from 1 week, 4 months and 6 months of age were used as the main outcome variables. Educational level of the mother was defined as the highest level on a three-grade scale, low, medium and high. Family type was defined as whether the mother was single or married/cohabiting. Family disposable income was divided into quartiles where quartile 1 included the 25% children in families with the lowest incomes. Analyses were conducted by logistic regression models using the methodology of generalized estimating equations (GEE). An exchangeable correlation structure was used to control for the dependence among infants with the same mother. RESULTS Breastfeeding rate in Sweden has declined gradually since the late 1990s. The results indicated that overall breastfeeding rates over the study period were influenced by socioeconomic status in a gradient manner but no widening socioeconomic gap was detected. Rather the interaction analyses showed a narrowing socioeconomic gap over the study period between high and low educational level and single versus cohabiting mothers at 4 months. The narrowing socioeconomic gap between the educational level categories was also detectable at 6 months. CONCLUSION No increase in socioeconomic gap was detected within the general decline in Swedish breastfeeding. However, there are reasons to maintain and strengthen the overall breastfeeding supportive measures including extended support for vulnerable groups.

Abstract
RATIONALE, AIMS AND OBJECTIVES There is an increasing recognition that early intervention is important for children with motor disorders. The use of standardized assessment methods within the Swedish Child Health Services (CHS) may improve early identification of these children and thereby their development and quality of care. Given the key role of nurses within the CHS, we explored their experiences of using a structured assessment of motor performance (SOMP-I) in a clinical setting, and investigated possible barriers and facilitators for implementation of the method within the CHS. METHODS The study was conducted in 2013 in Uppsala County, Sweden. Ten child health nurses participated in two focus group interviews, which were analysed using systematic text condensation. RESULTS The analysis yielded three themes: (1) increased knowledge and professional pride - nurses described their desire to provide high-quality care for which SOMP-I was a useful tool; (2) improved parent-provider relationship - nurses felt that using SOMP-I involved both the parents and their infant to a greater extent than routine care; and (3) conditions for further implementation - nurses described that the time and effort needed to master new skills must be considered and practical barriers, such as lack of examination space, resource constraints and difficulties in documenting the assessment must be addressed before implementing the SOMP-I method in routine care. CONCLUSION Child health nurses felt that the SOMP-I method fitted well with their professional role and increased the quality of care provided. However, significant barriers to implementing SOMP-I into routine child health care were described.

Abstract
Cervicogenic or cervical dizziness is debated as an entity. However, there exists both a physiologic basis and a multitude of clinical data to make such a disease concept at least possible and worth considering. In addition, the interaction of proprioceptive and vestibular mechanisms may amplify dizziness of other origin. Cervical pain and dizziness are both common symptoms and may coincide, and neck pain or obvious dysfunction does not necessarily cause dizziness or balance disturbances. So far, there is also the lack of a proper diagnostic test for cervicogenic dizziness. On the other hand, there is growing evidence that cervical proprioceptive input is important for balance and postural control not only in animals but also in humans, and that intervention in disorders affecting the human cervical segment may relieve dizziness in some patients. It is advocated that the diagnosis should be used with care and that there is a need for better diagnostic tests. In the absence of such a test, one has to rely on preliminary criteria and a diagnosis ex juvantibus. A possible approach would require patients to present with neck pain before or in close temporal relation with dizziness; that other causes should be made at least unlikely; and that treatment of a cervical dysfunction reduces also dizziness or balance disturbance.

Abstract
Balance control when standing upright is a complex process requiring input from several partly independent mechanisms such as coordination, feedback and feedforward control, and adaptation. Acute alcohol intoxication from ethanol is recognized as a major contributor to accidental falls requiring medical care. This study aimed to investigate if intoxication at 0.06 and 0.10% blood alcohol concentration affected body alignment. Mean angular positions of the head, shoulder, hip, and knee were measured with 3D-motion analysis and compared with the ankle position in 25 healthy adults during standing with or without perturbations, and with eyes open or closed. Alcohol intoxication had significant effects on body alignment during perturbed and unperturbed stance, and on adaptation to perturbations. It induced a significantly more posterior alignment of the knees and shoulders, and a tendency for a more posterior and left deviated head alignment in perturbed stance than when sober. The impact of alcohol intoxication was most apparent on the knee alignment, where availability of visual information deteriorated the adaptation to perturbations. Thus, acute alcohol intoxication resulted in inadequate balance control strategies with increased postural rigidity and impaired adaptation to perturbations. These factors probably contribute to the increased risk of falling when intoxicated with alcohol.

Abstract
RATIONAL, AIMS AND OBJECTIVES Increasing evidence highlights the importance of early interventions for motor disorders in children. Given the key medical role of the nurse within the Swedish Child Health Service (CHS), we aimed to examine if nurses could apply a structured assessment of early motor development at the child health centre to enable early identification of children at risk. METHODS Structured Observation of Motor Performance in Infants (SOMP-I) assesses infant's level of motor development and quality of motor performance using subscales converted to total scores. The total score for both level and quality can then be plotted within the SOMP-I percentile distribution at the child's age for comparison with a reference population. Fifty-five infants (girls: 30) were assessed according to SOMP-I at three child health centres. Assessments were performed by nurses (n = 10) in a clinical setting; one nurse performed the assessment while another nurse and a physiotherapist observed. RESULTS Agreement for the assessment of level as a continuous variable was excellent [intraclass correlation coefficient (ICC) 0.97-0.98], but was lower for quality (ICC 0.02-0.46). When the children were categorized according to the percentile range categories, the assessors were in agreement for the majority of the children, with respect to both level (78-82%) and quality (78-87%). CONCLUSION Despite brief experience with SOMP-I, the agreement was excellent when assessing the level of motor development, but was less satisfactory for the assessment of quality of motor performance. More extensive education and training may be necessary to improve the nurses' ability to assess quality, as this domain was an entirely new concept to the nurses. Further research is warranted to determine the applicability of SOMP-I as a standardized method for nurses to assess motor development within the CHS.
