  • Change in paternal grandmothers' early food supply influenced cardiovascular mortality of the female grandchildren
  • 2014
  • Ingår i: BMC Genetics. - : BioMed Central. - 1471-2156. ; 15, s. 12-
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: This study investigated whether large fluctuations in food availability during grandparents' early development influenced grandchildren's cardiovascular mortality. We reported earlier that changes in availability of food - from good to poor or from poor to good - during intrauterine development was followed by a double risk of sudden death as an adult, and that mortality rate can be associated with ancestors' childhood availability of food. We have now studied transgenerational responses (TGR) to sharp differences of harvest between two consecutive years' for ancestors of 317 people in Overkalix, Sweden. Results: The confidence intervals were very wide but we found a striking TGR. There was no response in cardiovascular mortality in the grandchild from sharp changes of early exposure, experienced by three of the four grandparents (maternal grandparents and paternal grandfathers). If, however, the paternal grandmother up to puberty lived through a sharp change in food supply from one year to next, her sons' daughters had an excess risk for cardiovascular mortality (HR 2.69, 95% confidence interval 1.05-6.92). Selection or learning and imitation are unlikely explanations. X-linked epigenetic inheritance via spermatozoa seemed to be plausible, with the transmission, limited to being through the father, possibly explained by the sex differences in meiosis. Conclusion: The shock of change in food availability seems to give specific transgenerational responses.

  • Hyperarousal, depression and quality of life - Validity and reliability of the Swedish version of the Hyperarousal Scale
  • 2006
  • Ingår i: Scandinavian Journal of Caring Sciences. - : Wiley. - 0283-9318 .- 1471-6712. ; 20:1, s. 58-67
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: Research focusing on hyperarousability in association with general sensitivity to stress has increased. This study aimed to: (i) describe values for self-reported hyperarousal behaviour traits, depression, sleeplessness behaviour and health-related quality of life [The Short Form 36 Health Survey Questionnaire (SF-36)] in a gender-stratified random sample from the Swedish population, and (ii) test the validity and reliability of the Swedish version of the Hyperarousal Behavioural Trait Scale (H-scale). Methods: In this study, 402 women and 391 men from Sweden were included. A test-retest study was performed on 297 subjects. Results: The total mean score on the H-scale was 29.5 (SD 10.0, 95% CI 28.8-30.2). Compared to men, women scored higher on the H-scale (total score, sub-scales and many items), whereas no evidence of an age trend was seen. The H-scale has proven to be a valid and reliable scale. Pearson's correlation coefficient showed similar magnitude and direction between the H-scale and the Zung's Self-rating Depression Scale, as between the H-scale and the Vicious Cycle of Sleeplessness Behaviour Scale, Vitality, Mental Health and the Mental Component Summary index on the SF-36 respectively. The Cronbach's alpha for the H-scale was 0.84 and estimated stability test-retest point of time varies between 0.73 and 0.80. Conclusions: This study indicates gender differences in response style in association with altered health-related quality of life. The H-scale is a valid and reliable self-reported scale for measuring hyperarousal behavioural trait research outcome in clinical practice. © 2006 Nordic College of Caring Science.

  • Predictive factors for 1-year and 5-year outcome for disability in a working population of patients with low back pain treated in primary care
  • 2006
  • Ingår i: Pain. - : Ovid Technologies (Wolters Kluwer Health). - 0304-3959 .- 1872-6623. ; 122:1-2, s. 137-144
  • Tidskriftsartikel (refereegranskat)abstract
    • Many patients seeking primary care for low back pain continue to report disability several years after their initial visit. The aims of this study were to assess the independent predictive value of a number of potential predictive factors for disability at the 1-year and 5-year follow-ups, and to examine whether prediction models were improved by replacing baseline health-state-related variables with corresponding variables after treatment. A further aim was to describe possible differences between those on sick leave, early retirement or disability pension, and those who were not. Baseline factors were age, gender, self-reported physical-activity-related and work-related factors, expectations of treatment, similar problems previously, duration of episode, more than one localization, sick leave, pain frequency, disability, and well-being. The study sample comprised 148 participants in a previous randomized trial who were eligible for sick-leave benefits. Multiple logistic regression was used to identify predictive factors. At the 5-year follow-up, 37% (n = 19/52) of the patients with disability were on sick leave or were receiving early retirement or disability pension. For those without disability the corresponding figure was 9% (n = 8/92). Being a woman, duration of the current episode, similar problems during the previous 5 years, exercise level before the current episode, pain frequency at baseline, and disability after treatment emerged as predictive factors for disability at the 5-year follow-up. Replacing baseline health-state-related measures with corresponding measures after the treatment period, and adding physical-activity-related and possibly work-related factors might improve the likelihood of predicting future disability.

  • Long-term prognostic and predictive factors in hormone receptor positive breast cancer
  • 2018
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • The breast cancer survival in Sweden is good (almost 90 % 5-year relative survival) and has increased over time. For women with hormone receptor negative tumors, most relapses occur within the first 5 years after diagnosis. Thereafter the recurrence risk decreases rapidly. For women with estrogen receptor positive (ER+) tumors the annual risk for late recurrences is 1 – 2 %, even after 5 years of endocrine therapy. This risk accumulates so that approximately 25 % of the patients that are recurrence-free after five years from diagnosis may experience a relapse within further 15 years of follow-up. The relatively high long-term risk calls for identification of prognostic and predictive markers with long-term effect. Though, the number of such markers with proven significance is limited. Of the clinical characteristics, only nodal status and to some extent tumor size and tumor grade have been shown to have long-term prognostic value. In this thesis, we propose long-term prognostic and predictive markers for breast cancer.In paper I, we suggest the protein v-akt murine thymoma viral oncogene homologue 2 (AKT2) as a long-term prognostic marker among patients with ER+ tumors. In our study, besides nodal status, AKT2 was the only factor with long-term prognostic value. This is in accordance with some other studies, though we also showed that the significance of AKT2 was limited to ER+ tumors and that the impact increased with higher ER expression.Approximately 75 – 85 % of the ER+ tumors are also progesterone receptor positive (PR+). ER+/progesterone receptor negative (PR-) tumors are considered to be more aggressive and patients with such tumors are often treated with chemotherapy. In this group, more specific subgroups for targeted therapy are needed.Whereas ER has long been established as a predictive factor regarding tamoxifen benefit, the role of PR has not been clarified to date. In paper II, we showed that PR status adds predictive value to ER considering the long-term benefit from tamoxifen.In paper III, we aimed to identify new prognostic markers among patients with ER+ tumors. Systemically untreated patients with ER+/PR- tumors and high expression of the Ras-related protein RAB6C (RAB6C) had reduced distant recurrence rate. Therefore, we suggest RAB6C as a candidate marker for subgroup division among patients with ER+/PR- tumors.According to the results from paper II, there might be subgroups of patients with ER+/PRtumors that do benefit from tamoxifen. The aim of paper IV was to identify such subgroups. Here, we suggest that patients with ER+/PR- tumors and low RAB6C expression do benefit from tamoxifen.The results from this thesis may encourage further studies for more specific subgroup divisions. Such studies may lead to changes in the management program, where some patients with ER+ tumors should receive prolonged or more intense treatment and others reduced treatment based on the pathological markers AKT2, PR and RAB6C.

  • Low RAB6C expression is a predictor of tamoxifen benefit in estrogen receptor-positive/progesterone receptor-negative breast cancer
  • 2020
  • Ingår i: Molecular and clinical oncology. - : SPANDIDOS PUBL LTD. - 2049-9450 .- 2049-9469. ; 12:5, s. 415-420

    • Over the last few decades, improved and more individualized treatment has contributed to the increased survival rate of patients with breast cancer. However, certain patients may receive excessive treatment resulting in undesired side effects. In a previous study, it was demonstrated that systemically untreated patients with estrogen receptor (ER)-positive/progesterone receptor (PR)-negative tumors with high Ras-related protein Rab-6C (RAB6C) expression levels (RAB6C(+)) had prolonged distant recurrence-free survival compared with that of patients exhibiting low RAB6C (RAB6C(-))-expressing tumors. The aim of the present study was to investigate whether RAB6C predicts the effectiveness of tamoxifen treatment. The present study used a dataset comprising 486 female patients with ER+ tumors from a randomized study conducted by the Stockholm Breast Cancer Study Group between November 1976 and August 1990. The patients were considered as low-risk if their tumor size was <= 30 mm and their lymph node status was negative. Patients were followed up until distant recurrence, mortality or when 25 years after randomization was achieved, whichever occurred first. For patients with ER+/PR-/RAB6C(+) tumors, prolonged distant recurrence-free survival could not be observed if the patients were treated with tamoxifen [hazard ratio (HR), 1.82; 95% confidence interval (CI), 0.69-4.79; P=0.23], whereas patients with ER+/PR-/RAB6C(-) tumors had 75% reduced distant recurrence risk (HR, 0.25; 95% CI, 0.09-0.70; P=0.008). In the ER+/PR+ subgroup, patients with RAB6C(-) and RAB6C(+) tumors benefited from tamoxifen treatment, though it was most evident in the RAB6C(+) group (HR, 0.27; 95% CI, 0.13-0.58; P=0.001). The results of the present study indicated that, for patients with ER+/PR- tumors, those with low RAB6C expression benefited from tamoxifen treatment, whereas no benefit was observed in patients with high RAB6C levels.

  • Association of NFKBIA polymorphism with colorectal cancer risk and prognosis in Swedish and Chinese populations
  • 2007
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 42:3, s. 345-350
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. The inhibitory proteins, IκBs, regulate the activity of nuclear factor kappa-beta (NF-κB), which is implicated in tumorigenesis by regulating expression of a variety of genes involved in cellular transformation, proliferation, invasion, angiogenesis and metastasis. Variants in the genes encoding IκBs may be involved in cancer development through the activation of NF-κB. The objective of this study was to investigate the susceptibility of an A to G variation (rs696) in the 3′ UTR of NFKBIA (encoding IκBα) to colorectal cancer (CRC) and the association of this polymorphism with clinicopathologic variables in CRC patients. Material and methods. A case-control study was carried out on a Swedish (155 CRCs, 438 controls) and a Chinese population (199 CRCs, 577 controls). The genotype of NFKBIA was determined by PCR-restriction fragment length polymorphism. Results. The frequency of the AG genotype was increased in the Chinese patients ≥50 years of age compared with the Chinese controls (odds ratio (OR) = 3.06, 95% confidence interval (CI) = 1.55-6.02, p=0.001), even when adjusted for age (OR = 3.20, 95% CI = 1.61-6.38, p=0.001). The GG genotype of NFKBIA was related to a poorer survival rate in the Swedish patients, independent of gender, age, tumour location, Dukes' stage and differentiation (hazard ratio = 3.10, 95% Cl = 1.28-7.60, p=0.01). Conclusions. Chinese individuals ≥50 years of age carrying the AG genotype of NFKBIA may be at an increased risk of developing CRC, and the GG genotype of NFKBIA may be considered as a prognostic factor for Swedish CRC patients. © 2007 Taylor & Francis.

  • Space-time clustering of childhood lymphatic leukaemias and non-Hodgkin's lymphomas in Sweden
  • 2000
  • Ingår i: European Journal of Epidemiology. - 0393-2990 .- 1573-7284. ; 16:12, s. 1111-1116
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The discussion concerning clusters of childhood leukaemia has mainly been focused on their relation to the time and place of diagnosis. Recently some studies have indicated clustering not only at diagnosis, but also around time and place of birth. Space-time clustering at time of birth could be of special interest if the aetiological agent is of infectious origin and the induction of leukaemia either occurs pre- or perinatally or an infection at that time favours a poor subsequent immune response to the agent. Methods: To identify possible space-time clustering we have used the close-pair method of Knox. One-thousand-twenty recorded cases (0-14 years) of childhood acute lymphatic leukaemia and 293 cases (0-14 years) of malignant non-Hodgkin's lymphoma from Sweden between 1973-1996 were analysed. The records include date of birth and of diagnosis as well as addresses at birth and at diagnosis. Results: A significant excess of case-pairs (25 observed, 14.9 expected, p = 0.01) was observed close in date and place of birth in the 4-14 year age group with acute lymphatic leukaemia (ALL). However there was no statistically significant clustering found around time of diagnosis. When the cases of leukaemia and the non-Hodgkin's lymphomas were combined no statistically significant clustering was obtained neither at birth nor at diagnosis. Conclusions: This study strengthens the evidence of space-time clustering around the birth date in children whom later developed ALL. This observation is in support of the hypothesis that pre- or perinatal infections can induce a process leading to ALL.

  • Caring externalities in health economic evaluation : How are they related to severity of illness?
  • 2005
  • Ingår i: Health Policy. - : Elsevier BV. - 0168-8510 .- 1872-6054. ; 73:2, s. 172-182
  • Tidskriftsartikel (refereegranskat)abstract
    • In health economic evaluations, altruistic preferences in the form of caring externalities, i.e. that people care about others' health, is usually not taken into account. In this study we examined how people value their own and others' health. This pilot study was carried out by letting people answer willingness to pay (WTP) questionnaires where internal WTP (own health) and altruistic WTP (others' health) were isolated and examined. A common method used in health economic evaluations is cost-utility analysis, which is based on the maximisation of QALYs. QALY maximisation may be appropriate if altruistic preferences are non-existent or if they are linear in relation to internal preferences (QALYs gained). We found evidence for the existence of altruistic preferences and that these preferences were relatively higher for severe health states (and lower for mild states of health) compared to internal preferences, i.e. when severity of illness increased, the relative increase in caring was higher concerning others than oneself. The difference was statistically significant (P < 0.001). Our results indicate that more attention and resources should be directed to severe health states, as compared to mild health states, than advocated by internal preferences in order to obtain more efficient resource allocation in the health care sector. © 2004 Elsevier Ireland Ltd.

  • Attitude towards remission induction for elderly patients with acute myeloid leukemia influences survival.
  • 2006
  • Ingår i: Leukemia. - : Springer Science and Business Media LLC. - 1476-5551 .- 0887-6924. ; 20:1, s. 42-47
  • Tidskriftsartikel (refereegranskat)abstract
    • Combination chemotherapy may induce remission from acute myeloid leukemia (AML), but validated criteria for treatment of elderly are lacking. The remission intention ( RI) rate for elderly patients, as reported to the Swedish Leukemia Registry, was known to be different when comparing the six health care regions, but the consequences of different management are unknown. The Leukemia Registry, containing 1672 AML patients diagnosed between 1997 and 2001, with 98% coverage and a median follow-up of 4 years, was completed with data from the compulsory cancer and population registries. Among 506 treated and untreated patients aged 70-79 years with AML (non-APL), there was a direct correlation between the RI rate in each health region ( range 36-76%) and the two-year overall survival, with no censored observations (6-21%) ( v 2 for trend = 11.3, P < 0.001; r(2) = 0.86, P < 0.02, nonparametric). A 1-month landmark analysis showed significantly better survival in regions with higher RI rates ( P = 0.003). Differences could not be explained by demographics, and was found in both de novo and secondary leukemias. The 5-year survival of the overall population aged 70-79 years was similar between the regions. Survival of 70-79-year-old AML patients is better in regions where more elderly patients are judged eligible for remission induction.
