Enduring inequality: educational disparities in health among the oldest old in Sweden 1992–2011

Objectives

Although the past two decades have involved changes in the living conditions of the oldest old in Sweden, little is known about how health inequalities have developed in this group during the period. This study explores the educational disparities in a wide range of health outcomes among the oldest old in Sweden between 1992 and 2011.

Methods

The study uses the repeated cross-sectional design of the SWEOLD survey, a nationally representative survey of the oldest old in Sweden with comparable data from 1992, 2002, and 2011. The development of educational disparities in health was tracked across the three waves.

Results

The results show that although the prevalence of most health problems increased during the period, the prevalence of disability in activities of daily living decreased. Despite these changes, educational disparities in health remained largely unaffected.

Conclusions

The results of the study suggest that the association between education and health is remarkably robust. It prevailed into the oldest age groups, was consistently found for a wide range of health problems, and tended to be stable over extended periods of time.

     

ESC Study Group of Sports Cardiology: recommendations for participation in leisure-time physical activity and competitive sports for patients with ischaemic heart disease.

BACKGROUND: Evidence for the proper management of ischemic heart disease (IHD) in the general population is well established, but recommendations for physical activity and competitive sports in these patients are scarce. The aim of the present paper was to provide such recommendations to complement existing ESC and international guidelines on rehabilitation and primary/secondary prevention. DESIGN AND METHODS: Due to the lack of studies in this field, the current recommendations are the result of consensus among experts. Sports are classified into low/moderate/high dynamic and low/moderate/high static, respectively. RESULTS: Patients with a definitive IHD and higher probability of cardiac events are not eligible for competitive sports (CS) but for individually designed leisure time physical activity (LPA); patients with definitive IHD and lower probability of cardiac events as well as those with no IHD but with a positive exercise test and high risk profile (SCORE > 5%) are eligible for low/moderate static and low dynamic (IA-IIA) sports and individually designed LPA. Patients without IHD and a high risk profile+ a negative exercise-test and those with a low risk profile (SCORE < 5%) are allowed all LPA and competitive sports with a few exceptions. CONCLUSIONS: Individually designed LPA is possible and encouraged in patients with and without established IHD. Competitive sports may be restricted for patients with IHD, depending on the probability of cardiac events and the demands of the sport according to the current classification.     

An association between human leucocyte antigen alleles and acute and chronic graft-versus-host disease after allogeneic haematopoietic stem cell transplantation

The association between various human leucocyte antigen (HLA) alleles and the occurrence of acute and chronic graft-versus-host disease (GVHD) was evaluated in 493 haematopoietic stem-cell transplant (HSCT) patients with HLA identical sibling donors. There were 307 men and 186 women with a median age of 30 years (0.2-77). Most of the patients had a haematological malignancy and received total body irradiation or busulphan combined with cyclophosphamide as conditioning before transplantation. GVHD prophylaxis consisted of monotherapy with methotrexate (MTX) or cyclosporin (CsA) in 118 patients, MTX + CsA in 323, T-cell depletion in 28 and other combinations in 24. In total, 84 patients (17%) received a peripheral blood stem-cell graft, whereas the rest received bone marrow. The cumulative incidence of acute GVHD grades II-IV was 20%, and chronic GVHD 46%. In the multivariate analysis, HLA-A10 (OR 2.14, CI 1.04-4.41, P = 0.03) and HLA-B7 (OR 1.80, CI 1.04-3.12, P = 0.03) correlated with an increased risk of acute GVHD grades II-IV. We also found an association between HLA-B27 (RR 0.60, CI 0.37-0.95, P = 0.04) and a lower incidence of chronic GVHD. These HLA alleles were independent of other known risk factors for acute or chronic GVHD, as shown by multivariate analysis. These results show that major histocompatibility comlex (MHC) alleles may influence the incidence of GVHD in HSCT with HLA identical sibling donors.     

Global microRNA profiling in favorable prognosis subgroups of cancer of unknown primary (CUP) demonstrates no significant expression differences with metastases of matched known primary tumors

No data exist on biologic differences between Cancer of unknown primary (CUP) and metastatic solid tumors of known primary site. We assigned a primary tissue of origin in 40 favorable CUP patients (A: serous peritoneal carcinomatosis n = 14, B: axillary adenocarcinoma n = 8, C: upper squamous cervical adenopathy n = 18) by means of a 64-microRNA assay. Subsequently, we profiled the expression of 733 microRNAs (miRs) in the CUP cases and compared results with metastases from 20 ovarian carcinomas, 10 breast adenocarcinomas, 20 squamous head neck or lung tumors. In the Peritoneal CUP versus Ovarian (Known Primary Metastases) KPM comparison, a total of 12 miR were significantly differentially expressed: higher than twofold expression difference in CUP was seen only for miR-513a-5p (3.7-fold upregulated) and miR-483-5p (2.5-fold upregulated), while miR-708 exhibited a twofold downregulation. In the Breast CUP versus Breast KPM comparison, only miR-29c that were downregulated in CUP by 2.7-fold satisfied the FDR threshold. miR-30e and miR-27b, downregulated in ovarian CUPs versus KPMs, were also non-significantly downregulated in breast CUP by 2.0- and 1.4-fold respectively. Six miRs, which belong to the 17–92 oncocluster showed a trend of upregulation in Breast CUP versus Breast KPM cases. A CUP signature remains elusive.     

Cardiorespiratory fitness protects against stress-related symptoms of burnout and depression

Objective

To examine how cardiorespiratory fitness and self-perceived stress are associated with burnout and depression. To determine if any relationship between stress and burnout/depression is mitigated among participants with high fitness levels.

Methods

197 participants (51% men, mean age = 39.2 years) took part in the study. The Åstrand bicycle test was used to assess cardorespiratory fitness. Burnout was measured with the Shirom–Melamed Burnout Questionnaire (SMBQ), depressive symptoms with the Hospital Anxiety and Depression Scale (HAD-D). A gender-matched stratified sample was used to ensure that participants with varying stress levels were equally represented.

Results

Participants with moderate and high fitness reported fewer symptoms of burnout and depression than participants with low fitness. Individuals with high stress who also had moderate or high fitness levels reported lower scores on the SMBQ Tension subscale and the HAD-D than individuals with high stress, but low fitness levels.

Conclusion

Better cardiovascular fitness seems to be associated with decreased symptoms of burnout and a better capacity to cope with stress.

Practical implications

Promoting and measuring cardiorespiratory fitness can motivate employees to adopt a more physically active lifestyle and thus strengthen their ability to cope with stress exposure and stress-related disorders.     

Detecting EGFR alterations in clinical specimens—pitfalls and necessities

We investigated the epidermal growth factor receptor (EGFR) status in early stage lung cancer in Southern Sweden, a population for which there are no previous reports on the EGFR mutation frequency. Three hundred fifty small cell lung cancers, adenocarcinomas (AC), squamous cell carcinomas (SqCC), and large cell carcinomas were analyzed using a combination of techniques for the analysis of protein expression, gene copy numbers, and mutations. Immunohistochemical (IHC) staining with antibodies for the EGFR mutations L858R and del E746-A750 revealed intratumoral heterogeneity and several discrepant cases when compared to mutation-specific polymerase chain reaction (PCR)-based analysis. The frequencies of these two mutations, when considering IHC staining with mutation-specific antibodies in a cohort of 298 cases and subsequent confirmation by PCR, were 10 % in AC and <2 % in SqCC. Furthermore, screening by sequencing of EGFR in a cohort of 52 lung AC and squamous carcinomas demonstrated a more diverse mutation spectrum, not covered by the mutation-specific antibodies. High expression of total EGFR protein was correlated to high gene copy numbers but did not reflect the mutational status of the tumors. We believe that the mutation spectra in a Southern Swedish population is too diverse to be covered by the mutation-specific antibodies, and we also raise some other issues regarding the use of the mutation-specific antibodies, for example concerning heterogeneous expression of the mutated protein, optimal antibody dilution, and discrepancies between staining results and PCR.     

Somatic Alterations Contributing to Metastasis of a Castration‐Resistant Prostate Cancer

Metastatic castration‐resistant prostate cancer (mCRPC) is a lethal disease, and molecular markers that differentiate indolent from aggressive subtypes are needed. We sequenced the exomes of five metastatic tumors and healthy kidney tissue from an index case with mCRPC to identify lesions associated with disease progression and metastasis. An Ashkenazi Jewish (AJ) germline founder mutation, del185AG in BRCA1, was observed and AJ ancestry was confirmed. Sixty‐two somatic variants altered proteins in tumors, including cancer‐associated genes, TMPRSS2‐ERG, PBRM1, and TET2. The majority (n = 53) of somatic variants were present in all metastases and only a subset (n = 31) was observed in the primary tumor. Integrating tumor next‐generation sequencing and DNA copy number showed somatic loss of BRCA1 and TMPRSS2‐ERG. We sequenced 19 genes with deleterious mutations in the index case in additional mCRPC samples and detected a frameshift, two somatic missense alterations, tumor loss of heterozygosity, and combinations of germline missense SNPs in TET2. In summary, genetic analysis of metastases from an index case permitted us to infer a chronology for the clonal spread of disease based on sequential accrual of somatic lesions. The role of TET2 in mCRPC deserves additional analysis and may define a subset of metastatic disease.
