Previous research has shown considerable marriage premiums in earnings for men, but often penalties for women of being in a union. In this study we extend this research by analyzing how the age difference between spouses affects the earnings profiles by gender. As we follow people over time in advance as well as within their marriage, we can separate premarital from postmarital earnings movements.

The overall tumour incidence and breast cancer incidence related to hormone replacement therapy (HRT) were followed in a population-based cohort of 29 508 women, aged 25-65 when interviewed in 1990-92. By the end of the follow up in December 1999, there were 226 611 person-years of observation. A total of 1145 malignant tumours were recorded (expected 1166.6; SIR = 0.98, 95% CI 0.93-1.04). There w

PURPOSE: Recent studies indicate that BRCA1 breast and ovarian tumors may have an advantageous survival. In this population-based study, the survival of carriers of a mutated BRCA1 gene was investigated.PATIENTS AND METHODS: The survival of 71 BRCA1-associated cancer patients (33 breast cancer, seven breast and ovarian cancer, and 31 ovarian cancer patients from 21 families with BRCA1 germline mut

Clustering of testicular cancer cases in families is well known, although the aetiology is not. We present the results of a segregation analysis performed with the algorithm Pointer on familial data on 978 Scandinavian patients with testicular cancer. The segregation analysis favoured the involvement of major gene effects over models incorporating solely polygenic effects in testicular cancer aeti

Background Fibroblast growth factor (FGF23) is a protein that is produced by osteoblasts and osteocytes. Increased serum levels of FGF23 have been associated with increased risks of osteoporotic fractures and cardiovascular disease, particularly in participants with poor renal function. Serum iron (Fe) has been suggested as a regulator of FGF23 homeostasis. Objective To determine whether Fe and ir

PURPOSE: The purpose of this study was to describe patients' experiences, with a focus on body image, 6 to 12 weeks after a stoma operation.METHOD: Nine patients (8 of whom received preoperative teaching) and who were expected to have their colostomy, ileostomy, or urostomy for at least 6 months were interviewed about their feelings, attitudes, and life experiences after undergoing ostomy surgery.

A negative association between interval length and infant and child mortality has been consistently identified in modern developing countries. The reasons for this association are unclear, however. Leading hypotheses explain these differences as a result of sibling competition, maternal depletion, infection transmission, or unobserved maternal factors, but none has received overwhelming support.
