BACKGROUND It is unclear whether estrogen receptor (ER)-status of first primary breast cancer is associated with risk of metachronous (non-simultaneous) contralateral breast cancer (CBC), and to what extent endocrine therapy affects this association. METHODS We studied the effect of ER-status of the first cancer on the risk of CBC overall, and for(More)
AIM To investigate whether overweight/obesity at diagnosis affects the chances of decrease in disease activity and pain in early rheumatoid arthritis (RA). METHOD We investigated incident RA cases from the population-based Epidemiological Investigation of risk factors for Rheumatoid Arthritis (EIRA) study (2006-2009, N=495) with clinical follow-up in the(More)
Estrogen receptor (ER) status is important for breast cancer survival, it is however unclear how prognosis of contralateral breast cancer (CBC) is affected by ER-status of the two tumors. We conducted a large, population-based study of ER-status of both tumors in CBC patients and its influence on prognosis. The cohort consisted of all women diagnosed with(More)
Mammographic density is a strong risk factor for breast cancer, but it is unknown whether density at first breast cancer diagnosis and changes during follow-up influences risk of non-simultaneous contralateral breast cancer (CBC). We collected mammograms for CBC-patients (cases, N = 211) and unilateral breast cancer patients (controls, N = 211),(More)
OBJECTIVES Physical activity has been shown to decrease inflammatory markers; here we investigate the effect on the clinical presentation of rheumatoid arthritis (RA). METHODS We used the cases from the population-based EIRA study (N=617), followed in the Swedish Rheumatology Quality Register, calculating the odds of having above median level of 28-joint(More)
OBJECTIVES Do recent infections affect the risk of rheumatoid arthritis (RA)? METHODS We used the population-based case-control study EIRA (N=6401) on incident RA and healthy controls, matched for sex, age, calendar period and area of residence. Gastroenteritis, urinary tract infection, genital infection, prostatitis, sinusitis, tonsillitis and pneumonia(More)
Women with contralateral breast cancer (CBC) have significantly worse prognosis compared to women with unilateral cancer. A possible explanation of the poor prognosis of patients with CBC is that in a subset of patients, the second cancer is not a new primary tumor but a metastasis of the first cancer that has potentially obtained aggressive characteristics(More)
Women who have been treated for breast cancer are typically followed up with regular mammography and palpation, with the aim of detecting recurrences and contralateral breast cancer (CBC). This study aims to investigate if the diagnostic work-up of breast cancer patients has improved over the last 25 years and resulted in earlier diagnoses of CBC. Two(More)
INTRODUCTION Oral anticoagulants in patients with atrial fibrillation (AF) with moderate-to-high stroke risk are strongly recommended by the current guidelines. MATERIALS AND METHODS Population-based register study of all 13,837 patients with incident non-valvular AF diagnosed during 2011-2014 in primary and secondary care (including all in- and(More)
