Purpose: Conventional hemodialysis (HD) treatment has an acceptable removal of small uremic molecules, but so-called middle molecules in the range of 0.5-60 kDa are poorly cleared with HD compared to a native kidney, which may contribute to morbidity in the dialysis population. Hemodiafiltration (HDF) has a better removal of middle molecules compared to HD but is technically demanding and requires well-functioning dialysis access. The newly introduced medium cutoff (MCO) filters have been developed to enhance middle molecule clearance in HD-mode. The aim of this study was to compare reduction ratios (RRs) of molecules with different molecular weights (0.06-150 kDa) during dialysis with MCO dialyzer (used in HD-mode) compared to online-hemodiafiltration (ol-HDF) treatment with a conventional high-flux dialyzer. Patients and Methods: This is a prospective controlled single-center cross-over study, including 16 patients in Malmo, Sweden. All patients had ongoing post-dilution ol-HDF treatment before the study. The study compared reduction ratios of small-, middle-, and large-sized molecules during a single 4h dialysis treatment with post-dilution ol-HDF (Polyflux 210H) to a 4h dialysis treatment with MCO dialyzer (Theranova 500) in HDmode. Between treatments, the patients had a washout period of at least two weeks of their ordinary HDF treatment to reach their ordinary steady state. Results: Ol-HDF had significantly higher RR for cystatin C (13 kDa), compared to MCO (RR 68.1 vs 65.8, p=0.003), during a 4h dialysis treatment (mean convection volume of 24.5 L for HDF, and mean Qb of 324 mL/min for HDF and 323 mL/min for MCO). There was no significant difference in the RR for other middle molecules, or for smaller or larger molecules. Conclusion: Overall, the RRs were comparable for ol-HDF and MCO-HD. There was a slightly higher RR of cystatin C (a small middle molecule) for HDF compared to MCO but no difference in other measured molecules. (Less)

Aim: To develop a high sensitivity and specific analytical method to measure endogenous levels of leukotriene B4 (LTB4) in human plasma. Methodology: LC–MS/MS and ELISA. Results: An LC–MS/MS method was developed with a sensitivity of 1.0 pg/ml, and within and between batch precision of 4 in human plasma. The LC–MS/MS method displayed correlation with a commercial LTB4 ELISA when analyzing in ex vivo ionophore-stimulated blood samples. For untreated plasma this correlation was lost. Endogenous LTB4 was shown to be unstable in plasma during storage at -20°C and subject to stereoisomer formation. Neither of the assays could quantify endogenous plasma LTB4 in samples stored for long term.

This paper describes the design, fabrication, and feasibility of paper-based optode devices (PODs) for sensing potassium selectively in biological fluids. PODs operate in exhaustive mode and integrate with a handheld, smartphone-connected optical reader. This integrated measuring system provides significant advantages over traditional optode membranes and other paper-based designs, by obtaining a linear optical response to potassium concentration via a simple, stackable design and by harnessing a smartphone to provide an easy-to-use interface, thus enabling remote monitoring of diseases.

Lymphocytes play a central role in the pathology of a range of chronic conditions such as autoimmune disease, transplant rejection, leukemia, lymphoma HIV/AIDs and cardiometabolic diseases such as atherosclerosis. Current treatments for lymphocyte-associated conditions are incompletely effective and/or complicated by a range of off-target toxicities. One major challenge is poor drug access to lymphocytes via the systemic blood and this may be attributed, at least in part, to the fact that lymphocytes are concentrated within lymph fluid and lymphoid tissues, particularly in gut-associated lymphatics. Here we demonstrate that promoting drug uptake into the intestinal lymphatics with a long chain fatty acid, thereby increasing lymphocyte access, enhances the pharmacodynamic effect of a highly lipophilic liver X receptor (LXR) agonist, WAY-252623, that has been suggested as a potential treatment for atherosclerosis. This has been exemplified by: (1) increased mRNA expression of key markers of LXR activation (ABCA1) and regulatory T cells (Foxp3) in local lymphatic lymphocytes and (2) enhanced numbers of CD4+CD25+Foxp3+ regulatory T cells in the systemic circulation, after administration of a 5-fold lower dose with a lymph directing lipid formulation when compared with a non-lipid containing formulation. These data suggest that combining lipophilic, lymphotropic drug candidates such as WAY-252,623, with lymph-directing long chain lipid based formulations can enhance drug targeting to, and activity on, lymphocytes in lymph and that this effect persists through to the systemic circulation. This presents a promising approach to achieve more selective and effective therapeutic outcomes for the treatment of lymphocyte associated diseases.

Problem: Emergency care in child and adolescent psychiatry often lacks a coherent treatment model. This study reports on the development and implementation of a salutogenic treatment model at the Child & Adolescent Psychiatric Emergency Unit in Malmo, Sweden. Methods: The development and implementation involved all staff categories and was guided by a recognized authority on salutogenesis. Generalized resistance resources (GRR) were identified that could be implemented at the unit to improve patients’ sense of coherence. Findings: Eight GRR were developed and implemented at the unit. During the 6-month period following the implementation, patients (n = 41) and parents reported satisfaction with the treatment, while mental health improved between admission and discharge, and both treatment length and readmission rates were reduced. Conclusion: A salutogenic treatment model involving GRR seems to be a promising approach in child and adolescent psychiatric emergency treatment.

Objective To investigate the frequency of physical activity among female pelvic cancer survivors (i.e., gynecological, rectal, and anal cancer survivors) and to investigate if survivors who practiced physical activity less than once a week differed from survivors practicing physical activity at least once a week with respect to urinary and fecal leakage, clinical and sociodemographic characteristics, quality of life (QoL), and depressed and anxious mood. Methods Female pelvic cancer survivors (n = 578, mean age 64 years) answered a questionnaire 6–48 months after radiotherapy. A multivariable regression model analyzed factors covarying with frequency of physical activity. We compared QoL and depressed and anxious mood between women practicing physical activity at least or less than once a week. Results Of 568 women delivering data, 186 (33%) practiced physical activity less than once a week while 382 (67%) practiced physical activity at least weekly. Women who leaked a large or all volume of stools (p = 0.01), had just elementary school level of education (p p = 0.049), or had lymphedema without receiving lymphedema treatment (p = 0.030) were more likely to practice physical activity less than weekly (50%, 45%, 45%, and 37%, respectively) compared with other women. Women practicing physical activity at least weekly reported better QoL (p p = 0.044) compared with the others. Conclusions Female cancer survivors experiencing fecal leakage were less likely to practice weekly physical activity than survivors without leakage. The survivors practicing weekly physical activity experienced better QoL and experienced depressed mood less frequently than the others.

This article describes a qualitative research study undertaken as a collaboration between museum and occupational therapy (OT) researchers to better understand museum experiences for families with a child or children impacted by autism spectrum disorder (ASD). Inclusion for visitors with ASD is an issue that museums are increasingly considering, and the social dimension of inclusion can be particularly relevant for this audience. The construct of social participation, used in OT, provides a promising avenue for museum professionals to think about inclusion. Social participation situates social and community experiences within the context of peoples’ diverse motivations and the strategies they use to navigate environments. This study took these multiple factors into account when observing families’ museum visits—including analysis of their motivations for visiting, environmental features that influenced their visit, family strategies used before and during the visit, and the families’ definitions o...

To investigate child healthcare nurses' experiences of asking mothers of 8-month-old children about intimate partner violence using a two-step questionnaire.Exposure to intimate partner violence is detrimental to women and to their children, and its early detection is vital. Child health care is a promising setting for detecting intimate partner violence.The overall project had a quasi-experimental design and was employed in 2015 at 12 child healthcare centres in Sweden. The project aimed to test a two-step method for talking about intimate partner violence with mothers (n = 198) at the child healthcare centre. In this article, we disclose the experiences of the intervention from the perspective of the nurses (n = 13) who were educated and involved in the intervention.Data were collected by semi-structured interviews, analysed by thematic analysis.Five categories emerged: using the two-step questionnaire method, asking about IPV as an important issue, being comfortable in the professional role and with asking about IPV, the importance of time and place in asking about IPV and spillover effects.Asking mothers visiting the child health clinic about their experiences of intimate partner violence was seen as an important task. Using a questionnaire could facilitate asking, but the questionnaire must be short and easy to use. Furthermore, the time and place for initiating a talk about this sensitive topic must be carefully chosen.The Violence in Families questionnaire was regarded as a useful tool and could thus be implemented in practice. However, it is important to offer education to the nurses prior to implementing a routine of asking about intimate partner violence in the child healthcare setting.

The Diabetes Incidence in Kronoberg (DIK) study of adult-onset diabetes used serological classification. Standard Mortality Rates (SMR) and Years of Life Lost (YLL) 15 years after adult-onset (18-100 years) of diabetes were compared to the population of Kronoberg.Of 1609/1660 (97%) patients, 112 (7%) had type 1 (T1D) (GADAFor T1D SMR did not differ from the Kronoberg population in any age group. In T2D SMR was 1.20 (1.12-1.29). After 15 years 26% (29/112) T1D and 52% (785/1497) T2D patients had died, p 0.0001. In T2D SMR was 5.6 (30-39 years), 2 (40-59 years), 1.4 (60-69 years), and thereafter no difference. There were no significant sex differences in mortality, and no YLL to adult-onset T1D, but five YLL to T2D for onset at ages 20-60 years.For adult-onset T1D SMR did not differ from the general population, in contrast to previous findings in childhood-onset (30 years of age) T1D. The difference in mortality between persons with diabetes and the general population was due to higher mortality in T2D.

The purpose of the present study is to describe how gynaecological cancer survivors (GCS) experience incontinence in relation to quality of life, their possibilities for physical activity and exercise and their perceptions and experiences of pelvic floor muscle training. This qualitative interview content analysis study included 13 women (48-82 age) with urinary (n = 10) or faecal (n = 3) incontinence after radiation therapy (n = 2), surgery (n = 5) and surgery and radiation therapy (n = 6) for gynaecological cancer, 0.5-21 years ago. Symptoms related to incontinence and restrictions in daily activities reduced physical quality of life. Emotions related to incontinence reduced psychological quality of life and social and existential quality of life, due to restrictions in activity and feelings of exclusion. Practical and mental strategies for maintaining quality of life were described, such as always bringing a change of clothes and accepting the situation. Possibilities for sexual and physical activity as well as exercise were also restricted by incontinence. The women had little or no experience of pelvic floor muscle training but have a positive attitude towards trying it. They also described a lack of information about the risk of incontinence. The women were willing to spend both money and time on an effective treatment for their incontinence. Nine out of 10 were willing to spend at least 7 h a week. GCS experienced that incontinence reduced quality of life and limited possibilities for sexual and physical activity as well as exercise. Coping strategies, both practical and emotional, facilitated living with incontinence. The women had a positive attitude towards pelvic floor muscle training. Lack of information had a negative impact on their way of dealing with the situation.

BACKGROUND: Female childhood cancer survivors are at risk of ovarian failure and premature ovarian insufficiency. We hereby present an interim analysis of a prospective observational study of ovarian function during cancer treatment of young females in relation to clinical factors. PROCEDURE: Thirty-four consecutive female cancer patients aged 0-18 year were included after informed consent. Serum/Plasma levels of anti-Mullerian hormone (AMH), inhibin B, FSH, LH, and oestradiol (E2) were measured at diagnosis and every 3-4 months during and after treatment. RESULTS: All patients had detectable AMH levels at diagnosis. Eleven patients had reached menarche (mean age 14½ years) and the remaining patients had a mean age of 6½ years. They all showed a rapid decline in AMH after 3 months of treatment, regardless of AMH at diagnosis, age, menarche, or treatment given. Those given radiotherapy below the diaphragm and/or stem cell transplantation (SCT) (n = 9) had no ovarian recovery during or 1½-year after treatment. However, recovery was observed in those given standard treatment for acute lymphatic leukemia (n = 7) already during maintenance chemotherapy. For the remaining patients, longer follow-up is required for analysis of ovarian recovery after treatment. CONCLUSIONS: Rapid ovarian dysfunction is observed in all females after initiation of cancer treatment as measured by AMH and inhibin B. Our data regarding those who require abdominal radiotherapy and/or SCT confirms the recommendations in the Nordic countries where these patients are eligible for cryopreservation of ovarian cortical tissue before start of cancer treatment.

We describe a new method for analysis of change in glaucomatous visual fields with the object to differentiate between changes caused by glaucoma from those caused by cataract. New pattern deviation change probability maps were developed from a prospectively collected glaucoma material and designed to be sensitive to changes in localized field loss, but to be unaffected by media-induced perimetric change. We compared the new change probability maps with the commercially available total deviation change probability maps in series of Humphrey perimetric tests in a glaucoma material of 43 eyes of 35 patients, who had undergone cataract surgery. When using the total deviation maps, considerable differences were seen between fields obtained before and after cataract surgery. Much smaller differences were seen when using the new change probability maps, that almost eliminated the common and disturbing effect of increasing cataract. This new tool could be of considerable help in differentiation between progressive glaucomatous visual field loss and deterioration caused by increasing media opacities.

This article reports on a study designed to explore how digital and physical reproductions of original artifacts could be incorporated into museum programs that teach visitors about mechanical motion. Museum visitors were introduced to 3 different types of models through 2 different programs: an engineering design challenge and an exhibit interpretation exploring mechanical motion in every-day objects. Research, based on visitor observation and interviews (n = 79), explored how user interaction with the digital and physical models compared with interactions with the original artifacts, assessed what effect the integration of digital and physical models had on learning, and examined what the learning experience looked like for learners using the mechanisms in the museum activities. Analysis of the learning conversations in additional in-depth case studies (n = 8) for both programs provides a detailed look at how visitors integrated the 3 different model types into their group's experience.

The two aims of this study were to analyse the impact of methadone on outcome, and to confirm the results from previous meta-analyses by using a different methodology. The literature on randomized controlled trials (RCT) of methadone as maintenance treatment for opioid dependence was systematically reviewed. Eight studies involving 1511 patients were included. Both dichotomous and continuous variables were transformed into the standardized effect size (d). Homogeneity was analysed. A random effect model was used in all calculations. The combined analyses for retention, abuse and criminality were all significant: d=0.90, d=0.61, and d=0.35, respectively. A test of heterogeneity was significant for all three outcomes: P0.01 for all comparisons. The type of study design was a significant moderator in five of nine comparisons: for retention in all three comparisons, concerning abuse in gradual detoxification vs. untreated controls and concerning criminality in placebo vs. untreated controls. In these sub-groups, three of six studies were homogeneous. In one study, methadone maintenance treatment reduced abuse of illegal opioids in prisoners. We conclude that methadone maintenance treatment in opioid dependence shows positive effects on retention, opioid abuse and criminality compared with non-active controlled conditions. Type of study design could explain some of the heterogeneity found. A different meta-analytical approach made it possible to confirm effects of methadone on retention and opioid abuse from previous studies and document effect on criminality.

Background Epidemiologic studies have shown conflicting results regarding the role of traffic pollution in the development of allergic disease. This study investigated the relationship between living close to traffic and ever dispense of prescribed oral antihistamines or nasal anti-allergic medication, among young children. The underlying aim was to investigate if children growing up close to traffic pollution are at higher risk of developing allergy in early childhood. Methods We investigated a birth cohort in southern Sweden, consisting of N = 26 128 children (0–6 years) with health outcome and exposure data. Of these children, N = 7898, had additional covariate information. Traffic intensity and yearly averages of dispersion-modeled concentrations of NOX (100 × 100 m grid) at residential addresses, were linked with registry data on dispensed allergy medication (the Swedish Prescribed Drug Register). Individual level covariate information was obtained from questionnaires distributed to parents at Child Health Care-center visits, eight months after birth. Cox proportional hazards regression was used for the statistical analyses. Results Living in close proximity to a road with equal to or greater than 8640 cars/day (compared to 0–8639 cars/day), was not associated with higher incidence of ever dispensed oral antihistamine or nasal anti-allergic medication, with or without adjustment for confounders (sex, breastfeeding, parental allergy, parental origin, season, and year of birth). Similar results were found in relation to NOX. Conclusions Traffic-related exposure was not associated with higher incidence of ever dispensed medication against allergy, in children 0–6 years in southern Sweden. These results indicates that traffic-related exposure may not be a risk factor for early onset allergy in children in southern Sweden. However, children with dispense of prescribed allergy medication may be a selected subgroup, and the results for this group may not be generalizable to all children with allergy.

The diagnosis and prognosis for 135 women with breast cancer and 99 women with ovarian cancer in a well-defined geographical area, and a follow-up of 7-15 years are described, based on patients' records. Diagnosis was initiated in primary care for 53% of women with breast cancer, and for 57% of women with ovarian cancer. Median patient delay was 1 week for breast cancer, and 3.5 weeks for ovarian cancer patients, and median provider delay was 3 weeks for both groups. Crude, relative, and corrected 5-year survival was 73%, 91%, and 82% in breast cancer, and 40%, 49%, and 43% in ovarian cancer. Cox multiple regression analyses showed that stage IIIA and IV, and young age were associated with impaired disease-related survival in breast cancer. In patients with ovarian cancer, stages III and IV at diagnosis, old age, and systemic symptoms dominating at presentation were predictive of reduced disease-related survival while a family history of cancer was predictive of increased survival.

Background Unaccompanied refugee minors (URMs) have high levels of psychiatric symptoms, and concerns for their access to mental health services have been raised. From the mid-2000s, an increasing number of asylum-seeking URMs, mainly adolescent boys from Afghanistan, have been referred to the Child & Adolescent Psychiatry emergency unit in Malmö, Sweden. The aim of the study was to compare inpatient psychiatric care between URMs and non-URMs. Findings All admissions in 2011 at the emergency unit were identified and divided into URMs (n = 56) and non-URMs (n = 205). On the basis of unique patients’ first treatment occasion, a group level analysis was performed on gender, age, treatment duration, additional treatment occasions/patient, involuntary care, involuntary care by gender, and ICD-10 principal diagnosis. To retrieve further sample characteristics, a questionnaire was administered to the physicians responsible for admitting patients in 2011. More URMs than non-URMs exhibited self-harm or suicidal behaviour in conjunction with referral. 86% of URMs were admitted with symptoms relating to stress in the asylum process. In the catchment area, 3.40% of the URM population received inpatient care and 0.67% inpatient involuntary care, compared to 0.26% and 0.02% respectively of the non-URM population, both comparisons p Conclusion From an epidemiological perspective, URMs were overrepresented in inpatient psychiatric care.

The Narodichesky region, Zhitomir Oblast, Ukraine, is situated ∼80 km from the Chernobyl Nuclear Power Plant, which exploded in 1986 and polluted the environment. A previous study found that children living in villages with high activity of (137)Cesium (Cs) in the soil had decreased levels of hemoglobin, erythrocytes and thrombocytes. These findings motivated the present study that used a more comprehensive exposure assessment, including individual whole-body concentrations (WBC) of (137)Cs (Bq/kg). This cross-sectional sample examined between 2008-2010, included 590 children in the age 0-18 years. Children with higher individual log(WBC) activity in the body had significantly decreased hemoglobin, erythrocyte and thrombocyte counts. The effect of log(WBC) on decreased thrombocyte count was only seen in children older than 12 years. The average village activity of (137)Cs (kBq/m(2)) in soil was associated with decreased blood counts only indirectly, through (137)Cs in the body as an intermediate variable. Children in this study were born at least 4 years after the accident and thus exposed to low doses of ionizing radiation from (137)Cs. This cross-sectional study indicates that low levels may be associated with decreased blood counts, but we cannot exclude that these results are due to residual confounding factors.Journal of Exposure Science and Environmental Epidemiology advance online publication, 25 September 2013; doi:10.1038/jes.2013.60.

Assessing the results of modern cystic fibrosis (CF)-care and estimating the future population and its demography is important to evaluate the treatment regimens and to calculate the future needs of health-care resources.This paper updates previous incidence calculations. It assesses the results of modern CF-care in terms of survival and changing demography in Sweden. The incidence of CF in Sweden was calculated as 1/5600 live-births. Of the CF-population alive in 1999, 45% were > or = 18 years old. The mean annual mortality rate since 1991 was 0.9% (+/-0.4) and the median age at death 26 years (range 0-72). Of those born > or = 1991, 95% were estimated to survive their 25th birthday. The incidence of CF in Sweden is low. Modern CF-care in Sweden shows good results. The CF-population is growing rapidly and the adult part of the population will soon be larger than the paediatric. Continuously adapted resources are required to assure the future treatment quality especially for the growing adult CF-population. (Less)

Clinical decisions often entail in intertemporal trade-off. Moreover, they often involve physicians of different specialities. In an experiment dealing with the management of small asymptomatic abdominal aortic aneurysms (a clinically relevant problem) we find that specialists in internal medicine exhibit higher implicit discount rates than vascular surgeons, general practitioners, and actual and prospective patients. Several personal characteristics expected to be directly related to pure time-preference and risk aversion (gender, smoking habits, age, place of employment) have the hypothesised effects. Additionally, financial incentives appear to affect the estimated implicit discount rates of physicians, but are unlikely to have caused the inter-group differences. Differences in discount rates could lead to variations in clinical practice, which may conflict with equality of treatment or equal access to health care. Copyright © 2002 John Wiley & Sons, Ltd.

STUDY OBJECTIVE—To assess whether in an urban population stage at breast cancer diagnosis is related to area of living and to what extent intra-urban differences in breast cancer mortality are related to incidence respectively stage at diagnosis. DESIGN—National registries were used to identify cases. Mortality in 17 residential areas was studied in relation to incidence and stage distribution using linear regression analysis. Areas with high and low breast cancer mortality, incidence and proportion of stage II+ tumours at diagnosis were also compared in terms of their sociodemographic profile. SETTING—City of Malmo in southern Sweden. PATIENTS—The 1675 incident breast cancer cases and 448 deaths that occurred in women above 45 years of age in Malmo 1986-96. MAIN RESULTS—Average annual age standardised breast cancer mortality ranged between residential areas, from 35/105 to 107/105, p=0.04. Mortality of breast cancer was not correlated to incidence, r= 0.22, p=0.39. The ratio of stage II+/0-I cancer incidence varied between areas from 0.45 to 1.99 and was significantly correlated to breast cancer mortality, r= 0.53, p=0.03. Areas with high proportion of stage II+ cancers and high mortality/incidence ratio were characterised by a high proportion of residentials receiving income support, being foreigners and current smokers. CONCLUSIONS—Within this urban population there were marked differences in breast cancer mortality between residential areas. Stage at diagnosis, but not incidence, contributed to the pattern of mortality. Areas with high proportion of stage II+ tumours differed unfavourably in several sociodemographic aspects from the city average. Keywords: breast cancer mortality; tumour stage; sociodemographic factors

Objective To test the stress hypothesis that women who give birth to small for gestational age infants lack important psychosocial coping resources, such as a sufficient social network, social support and control in daily life. Design A prospective cohort study of nulliparous pregnant women. Setting Antenatal care units in the city of Malmo, Sweden. Population All women (n = 994) during a one year period (1991-1992) were invited, and 872 (8707%) participated. This study was restricted to pregnancies resulting in singleton live birth (n = 826); 6.7% of infants were classified as small for their gestational age. Methods Self-administered questionnaires were given to all women at the time of their first antenatal visit. Main outcome measures The classification of small for gestational age was based on a gender-specific intrauterine growth reference curve. Newborn babies were classified as being small for gestational age if their birthweight was > 2 SD below the mean weight for gestational age. Lack of psychosocial resources, such as social stability, social participation, emotional and instrumental support, all increased the likelihood of delivering an infant that was small for gestational age. The odds ratios when controlled for demographic background factors, lifestyle factors and anthropomorphic measures were: OR 1.7 (95% CI 0-9-3.3) for women with poor social stability; OR 2.2 (95% CI 1.144) for women with poor social participation; OR 2.6 (95% CI 1.2-5.7) for women with poor instrumental support; and OR 1.5 (95% CI 04-24) for women with poor emotional support. Simultaneous exposure to a poor total network index, as well as a poor total support index showed a significantly increased odds ratio for having a small for gestational age baby: OR 3.3 (95% CI 16-67) and OR 2-7 (95% CI 1.3-5.6), respectively. A synergy index of 9.0 and 6.8 supported the assumption of an interaction between immigrant status and poor total network or poor total support, in a synergistic direction. The findings support the stress-hypothesis that a lack of psychosocial resources might increase the risk of giving birth to a baby that is small for gestational age. Results

The present paper presents the relationship between the total body-pain (TBP) score, defined as the total number of areas shaded on a pain drawing, and the pain from one area, the Shoulder-Neck (SN), among subjects in or out of full-time gainful work respectively. Furthermore, relationships between pain-score, self-experienced health (SEH) and level of mental distress, measured with the General Health Questionnaire (GHQ) were investigated. The analyses is based on a general population sample of 8,116 men and women, 45-60 years of age, completing a questionnaire in the Malmo Shoulder Neck Study. The TBP-score was higher with increasing pain from the SN area, being out of full-time work and among women. Independently of working status, the SEH decreased with increasing pain in the SN area, which was enhanced, by increasing TBP-score. The proportion of women out of full-time gainful work was twice as high as for men. Women showed the same SEH levels with regard to their pain status, independently of their working status while men working full-time scored higher than women did. Oppositely, men out of full-time work had the lowest SEH in relation to their pain status. The GHQ scores of mental distress varied essentially in the same way as the SEH did. The results emphasize the need for an assessment of the number of pain locations and which one that first gave symptoms when studying possible causal relationships between low force musculoskeletal load and development of localized pain. If such data are not collected in epidemiological studies on causes for musculoskeletal pain it will at best lead to unnoticed effect modifications. At worst a potential confounding situation may occur. The relationship between the self-experienced health, mental distress and chronic pain identifies chronic pain as a major public-health problem and suggests a multidisciplinary approach in the treatment and rehabilitation already before work capacity is lost.

Every child with severe or moderate haemophilia A or B, born in Sweden during the period 1970-1990, was treated in the national haemophilia register, all 117 case records being surveyed for mode of delivery and perinatal complications. Of the 117 deliveries, 13 were by caesarean section and the remaining 104 vaginal. Of the 13 caesarean sections, 2 were performed because the woman was a haemophilia carrier, the remaining 11 (5 emergency, 6 elective) for other reasons. Neonatal complications were: subgaleal or cephalic haematoma (n = 12), intracranial haemorrhage (n = 4), umbilical bleeding (n = 4), haematuria (n = 1), retro-orbital bleeding (n = 1) and abnormal bleeding after surgery, injection or venepuncture (n = 28). Of the 12 infants with subgaleal/cephalic haematoma, 10 were delivered by vacuum extraction. Seven more infants were delivered by vacuum extraction and another 11 were born without abnormal bleedings after laborious (> 24 h) delivery. Of the 4 children with intracranial haemorrhage, all were sporadic cases of haemophilia, 1 was a premature birth by caesarean section in the 27th week, I was delivered by vacuum extraction and the remaining 2 vaginally. In these 4 cases there were no sequelae or only minor ones. We conclude that the risk of serious bleeding in conjunction with normal vaginal delivery is small, but that vacuum extraction should be avoided when delivering offspring of haemophilia carriers.

OBJECTIVE: To perform an ecological study in an effort to generate questions concerning the preventive impact of various cardiovascular drugs on mortality from stroke and ischaemic heart disease (IHD) in the community, and to explore the association between sales of nitrates and mortality from stroke and IHD. METHODS: Out-patient drug utilization (sales) of blood pressure lowering drugs, lipid lowering drugs and nitrates were categorized in four groups of equal size by quartiles and compared with mortality from IHD and stroke, using the group of municipalities with the lowest utilization as reference, from 1989 to 1993 in 283 of Sweden's 288 municipalities, by Poisson regression. Adjustments were made for population size, age and gender proportions, the utilization rate of cardiovascular drugs other than the tested drug group and location of the municipality. RESULTS: Compared with the group of municipalities with the lowest sales and adjusting only for population size, mortality from IHD and stroke increased with the extent of utilization of blood pressure lowering drugs and nitrates. In contrast, mortality decreased with increased utilization of lipid lowering drugs. After further adjustments by percentage of men, age structure, geographical location (mid-points) of the municipalities, and, as a proxy for cardiovascular disease, the sales of cardiovascular drugs other than the tested drug group, the increased risk associated with blood pressure lowering drugs disappeared, and there was a dose-response association between sales of diuretics and old antihypertensives and decreasing mortality, sales of nitrates continued to be associated with an increased risk, and the low mortality risk associated with sales of lipid lowering drugs persisted. CONCLUSION: Lipid lowering drugs may have a preventive impact in the general population, but the preventive impact of blood pressure lowering drugs, with the exception of diuretics and old antihypertensives, may be low in many municipalities.

Background Previous studies have indicated that survivors of childhood acute lymphoblastic leukemia (ALL) have an increased morbidity measured in terms of health care utilization. However, earlier studies have several potentially important limitations. To overcome some of these, we investigated hospital contact rates, and predictors thereof, among 5-year survivors of ALL in a population-based setting, and compared them to a control cohort regarding outcome measures from a comprehensive nation-wide health register. Methods All individuals diagnosed with ALL before the age of 18 in Southern Sweden during 1970–1999 and alive January 2007 (n = 213; male = 107) were identified through the Swedish Cancer Register. Each subject was matched to fifty controls, identified in the Swedish Population Register. All study subjects were linked to the National Hospital Register and detailed information was obtained on all hospital contacts (hospital admissions and outpatients visits) starting five years after cancer diagnosis, and the corresponding date for the controls, until 2009. Results The median follow-up among the 5-year survivors of ALL was 16 years (range 5–33), accruing a total of 3,527 person-years. Of the 213 5-year survivors, 105 (49.3%) had at least one hospital contact compared to 3,634 (34.1%) of the controls (p

Background . Genuine Euro-Collins solution is calcium free. The aim of this study was to investigate whether the addition of calcium would improve its capacity to preserve the vasculature. Methods . The infrarenal aorta of Sprague-Dawley rats was investigated in organ baths: as fresh controls, after 24 hours of cold (4°C) storage in Euro-Collins solution, or in Euro-Collins solution with the addition of calcium in amounts ranging from 0.05 to 1.5 mmol/L. The thromboxane analogue U-46619 was used to investigate contractility. Endothelium-dependent relaxation was tested by cumulative addition of acetylcholine. Papaverine was used to elicit endothelium-independent relaxation. Investigation by transmission electron microscopy was also performed. Results . Storage of rat aorta for 24 hours in genuine Euro-Collins solution almost abolished smooth muscle function, and severe edema was found in the endothelial cells. However, if calcium was added, the rat aorta could be stored for 24 hours without affecting smooth muscle function, and endothelium-dependent relaxation was only slightly reduced. Furthermore, only slight edema could be demonstrated in the endothelial cells. Conclusions . If calcium is added to Euro-Collins solution in amounts ranging from 0.4 to 1.5 mmol/L, it allows good preservation of rat aorta for 24 hours. Without calcium, this solution destroys both the function and morphology of the vessels. (Ann Thorac Surg 1997;63:408–13)

We propose a way to estimate a parametric quantile function when the dependent variable, e.g. the survival time, is censored. We discuss one way to do this, transforming the problem of finding the p-quantile for the true, uncensored, survival times into a problem of finding the q-quantile for the observed, censored, times. The q-value involves the distribution of the censoring times, which is unknown. The estimation of the quantile function is done using the asymmetric L1 technique with weights involving local Kaplan-Meier estimates of the distribution of the censoring limit.

Background: Recent reviews conclude an association between traffic-related pollution and incidence of asthma in children, but not all studies agree. Studies have almost exclusively relied on parental-reported symptoms or parental-reported diagnoses of asthma and wheeze. Our aim was to investigate if traffic exposure is associated with higher incidence of early onset asthma, using registry-based outcome data. Methods: We investigated a birth cohort in southern Sweden, consisting of N = 26 128 children with outcome and exposure data (born July 2005-2010). Of these children, N = 7898 had additional covariate information. The cohort was followed to the end of 2011. Traffic intensity, and dispersion-modeled concentrations of NOX (100x100 m grid), at residential addresses, were linked with registry data on dispensed asthma medication (the Swedish Prescribed Drug Register), and hospital and primary health care diagnoses of bronchiolitis, obstructive bronchitis and asthma (The Scania Health Care Register). Covariate information was obtained from questionnaires distributed to parents at Child Health Care-centre visits, eight months after birth. Cox proportional hazards regression was used for the statistical analyses. Results: Living in close proximity to a road with >= 8640 cars/day (compared to 0-8640 cars/day), was not associated with higher incidence of first purchase of inhaled beta(2)-agonist (adjusted hazard ratio (adj.HR) = 0.9, 95% CI: 0.8-1.0); third year purchase of inhaled beta(2)-agonist (adj.HR = 0.7, 95% CI: 0.6-0.9); bronchiolitis (adj.HR = 0.7, 95% CI: 0.6-0.9), obstructive bronchitis (adj.HR = 1.0, 95% CI: 0.9-1.2), or asthma (adj.HR = 0.7, 95% CI: 0.6-0.9). Similar results were found for inhaled corticosteroids, and in relation to NOX. Conclusions: Traffic-related exposure was not associated with higher incidence of asthma medication, or diagnoses of asthma, bronchiolitis, or obstructive bronchitis, in children 0-6 years in southern Sweden. This may depend on the low levels of traffic pollution in the area, mainly well below the WHO-guideline for NO2.

The Narodichesky region, Zhitomir Oblast, Ukraine, is situated ∼80 km from the Chernobyl Nuclear Power Plant, which exploded in 1986 and polluted the environment. A previous study found that children living in villages with high activity of (137)Cesium (Cs) in the soil had decreased levels of hemoglobin, erythrocytes and thrombocytes. These findings motivated the present study that used a more comprehensive exposure assessment, including individual whole-body concentrations (WBC) of (137)Cs (Bq/kg). This cross-sectional sample examined between 2008-2010, included 590 children in the age 0-18 years. Children with higher individual log(WBC) activity in the body had significantly decreased hemoglobin, erythrocyte and thrombocyte counts. The effect of log(WBC) on decreased thrombocyte count was only seen in children older than 12 years. The average village activity of (137)Cs (kBq/m(2)) in soil was associated with decreased blood counts only indirectly, through (137)Cs in the body as an intermediate variable. Children in this study were born at least 4 years after the accident and thus exposed to low doses of ionizing radiation from (137)Cs. This cross-sectional study indicates that low levels may be associated with decreased blood counts, but we cannot exclude that these results are due to residual confounding factors.

Follow-up methods must be easy for young people to handle. We examine Interactive Voice Response (IVR) as a method for collecting self-reported data. Sixty inpatients were recruited from a child and adolescent psychiatric emergency unit in Malmö, Sweden and called every second (N = 30) or every fourth (N = 30) day from discharge until first visit in outpatient care. A pre-recorded voice asked them to evaluate their current mood using their mobile phones. Average response rate was 91%, and 71% had a 100% response rate. Gender, age and length of inpatient treatment did not affect response rate, nor did randomisation. Boys estimated their current mood on average as 3.52 units higher than girls, CI = (2.65, 4.48). Automated IVR is a feasible method of collecting follow-up data among adolescents discharged from a psychiatric emergency unit.

Female childhood cancer survivors are at risk of ovarian failure and premature ovarian insufficiency. We hereby present an interim analysis of a prospective observational study of ovarian function during cancer treatment of young females in relation to clinical factors.Thirty-four consecutive female cancer patients aged 0-18 year were included after informed consent. Serum/Plasma levels of anti-Müllerian hormone (AMH), inhibin B, FSH, LH, and oestradiol (E2) were measured at diagnosis and every 3-4 months during and after treatment.All patients had detectable AMH levels at diagnosis. Eleven patients had reached menarche (mean age 14½ years) and the remaining patients had a mean age of 6½ years. They all showed a rapid decline in AMH after 3 months of treatment, regardless of AMH at diagnosis, age, menarche, or treatment given. Those given radiotherapy below the diaphragm and/or stem cell transplantation (SCT) (n = 9) had no ovarian recovery during or 1½-year after treatment. However, recovery was observed in those given standard treatment for acute lymphatic leukemia (n = 7) already during maintenance chemotherapy. For the remaining patients, longer follow-up is required for analysis of ovarian recovery after treatment.Rapid ovarian dysfunction is observed in all females after initiation of cancer treatment as measured by AMH and inhibin B. Our data regarding those who require abdominal radiotherapy and/or SCT confirms the recommendations in the Nordic countries where these patients are eligible for cryopreservation of ovarian cortical tissue before start of cancer treatment.

Despite prostate cancer being the most frequent cancer in men in the Western world, tissue biomarkers for predicting disease recurrence after surgery have not been incorporated into clinical practice. Our group has previously identified β-microseminoprotein (MSMB) and cysteine-rich secretory protein-3 (CRISP3) as independent predictors of biochemical recurrence after radical prostatectomy. The purpose of the present study was to use automated image analysis, enabling quantitative determination of MSMB and CRISP3 expressions in a large cohort and to validate the previous findings. MSMB and CRISP3 protein expressions were assessed on tissue microarrays constructed from 3268 radical prostatectomy specimens. Whole-slide digital images were captured, and a novel cytoplasmic algorithm was used to develop a quantitative scoring model for cytoplasmic staining. Classification regression tree analysis was used to group patients, with different risk for biochemical recurrence, depending on level of protein expression. Patients with tumors expressing high levels of MSMB had a significantly reduced risk for biochemical recurrence after radical prostatectomy (HR=0.468; 95% CI 0.394-0.556; P

Background Wnt5a is a non-canonical secreted glycoprotein of the Wnt family that plays an important role in cancer development and progression. Previous studies report that Wnt5a is upregulated in prostate cancer and suggested that Wnt5a affects migration and invasion of prostate tumor cell. This study aimed to evaluate the prognostic value of Wnt5a protein expression in prostate cancer tissue and its potential to predict outcome after radical prostatectomy in patients with localized prostate cancer. Methodology and Results Immunohistochemical analysis of a tissue microarray containing prostate specimens of 503 patients with localized prostate cancer showed significantly higher Wnt5a protein expression in cancer compared to benign cores from the same patients (p

Objective. Prostate cancer antigen 3 in urine (uPCA3) has been shown to perform better than total prostate-specific antigen in serum (tPSA) to predict prostate cancer (PCa) detection. The aim of this study was to validate the diagnostic precision of uPCA3 in a mixed set of patients with no previous history of PCa, including patients with previous negative biopsies. Material and methods. The study included 62 men scheduled for prostate biopsy at Skane University Hospital Malmo, Sweden. Urine samples were obtained according to the Progensa™ uPCA3 assay. Logistic regression and receiver operating characteristic curves were used to test associations between levels of biomarkers and prostate cancer. Results. According to pathological examination of core needle biopsies, PCa was found in 18 out of 62 patients. A one-step increase in uPCA3 was associated with an increase in the odds of cancer of 1.026 (p = 0.005). Differences in the odds ratio between uPCA3 and tPSA were not statistically significant. A model using both markers did not increase prediction of event. Areas under the curve for uPCA3, tPSA and a model combining uPCA3 and tPSA did not differ significantly. No significant correlation was found between uPCA3 and tPSA or prostate volume. Conclusion. In this small set of mixed patients uPCA3 alone and tPSA performed equally well as diagnostic markers for PCa. A combination of the two markers did not improve the diagnostic performance. This study does not support a role for the uPCA3 urine test to replace or be added to tPSA in PCa detection. (Less)

BACKGROUND: The increasing number of survivors after childhood cancer requires characterization of the late complications of these diseases and their treatment. We examined a large number of possible socio-economic late effects following treatment for acute lymphoblastic leukemia (ALL) in order to identify factors leading to a poor outcome. PROCEDURE: All individuals who had been diagnosed with ALL and who were alive in January 2007 (n = 213; men = 107) were identified from a database of all patients with cancer before the age of 18 in Southern Sweden from 1970 to 1999. For each subject, 50 matched controls were identified from the Swedish Population Register. Information on marital status, children, education, employment, income, and support from the community was obtained from Statistics Sweden. RESULTS: At the ages of 25 and 30, survivors of ALL had attained a lower level of education than controls. At the age of 30, they were less often employed (70% vs. 82%, P = 0.019), less often married (19% vs. 32%, P = 0.019), and had children to a lesser extent (31% vs. 47%, P = 0.011) than controls. We identified young age at diagnosis as a risk factor for adverse outcome in the majority of the socio-economic variables studied, apart from the known risk of cranial irradiation treatment. Furthermore, female survivors had a greater risk of achieving a lower level of education than both male survivors and controls. CONCLUSIONS: Young age at diagnosis, as well as treatment with cranial irradiation, is a risk factor for socio-economic late effects after treatment for ALL in childhood.

Background Most epidemiologic studies use traffic at residential address as a surrogate for total traffic exposure when investigating effects of traffic on respiratory health. This study used GIS (Geographical Information Systems) to estimate traffic exposure, not only on residential, but also on workplace address, in addition to survey questions on time spent in traffic during commuting or other daily activities. The aim was to investigate 1) if there is an association between traffic exposure and prevalence of adult asthma and asthma symptoms, and 2) if so, does this association become stronger using more complete traffic exposure information. Methods This study was conducted in two stages: A first cross-sectional survey in Southern Sweden 2004 (n = 24819, 18-80 years, response rate 59%) was followed by a case-control study in 2005 to obtain more detailed exposure and confounder information (n = 2856, asthmatics and controls (1:3), 86% response rate). In the first survey, only residential address was known. In the second survey, questions about workplace addresses and daily time spent in traffic were also included. Residential and workplace addresses were geocoded and linked with GIS to road data and dispersion modelled outdoor concentrations of NOx (annual mean, 250 × 250 m resolution). Results Living within 50 m of a road (measured by GIS) with traffic intensity of >10 cars/minute (compared with no road within this distance) was associated with an increased prevalence of asthma, (OR = 1.8, 95% CI = (1.1-2.8), and with asthma symptoms last 12 months. No statistically significant effects were seen for traffic exposure at workplace address, daily time spent in traffic, or commuting time to work, after adjustment for confounders. A combined total exposure estimate did not give a stronger association with asthma prevalence or asthma symptoms. Conclusions Traffic exposure at close proximity to residential address showed association with asthma prevalence and asthma symptoms last 12 months, among adults in southern Sweden. The associations were not stronger when accounting for total traffic exposure. This could reflect exposure misclassfication at workplace address and for other daily time in traffic, but also that residential address remains the main determinant for traffic exposure among adults.
