Evaluation of age-specific causes of death in the context of the Italian longevity transition.

In many low-mortality countries, life expectancy at birth increased steadily over the last century. In particular, both Italian females and males benefited from faster improvements in mortality compared to other high-income countries, especially from the 1960s, leading to an exceptional increase in life expectancy. However, Italy has not become the leader in longevity.

Effect of the number of removed lymph nodes on prostate cancer recurrence and survival: evidence from an observational study.

Background: The aim of this article is to analyze the effect on biochemical recurrence and on overall survival of removing an extensive number of pelvic lymph nodes during prostate cancer surgery. The lack of evidence from randomized clinical trials to address this specific question has hampered the ability to determine the true effect of the number of nodes removed.

Results: Our analysis is based on a large observational study, and this can lead unadjusted estimates to be very sensitive to confounding bias due to the different prognosis of individuals.

Psychological distress of marital and cohabitation breakups.

Using data from a large survey, the British Household Panel Survey (BHPS), this paper explores the extent to which marital and cohabiting unions differ with respect to the short-term effects of union dissolution on mental health. We compare married individuals who divorced or separated with cohabitors whose first union ended and test the hypothesis that married individuals experience larger negative effects. Results show that initial differences are not statistically significant once the presence of children is controlled for, suggesting that the presence of children is a particularly significant source of increased psychological distress in union dissolutions.
