Ageing male syndrome, andropause, androgen decline or mid-life crisis?

Reports of a “male menopause” have been appearing in the literature since the 1930s [1] [2] . The Heller and Myers paper of 1944 was seen by some as a ’landmark paper where symptoms of age-related low testosterone were shown to be reversed by testosterone replacement, but not by placebo [3] . The “male menopause” has been referred to as the andropause, viropause and the male climacteric [1] [4]...

The State of Election Studies: Mid-Life Crisis or New Youth?

In a number of countries Michigan style national election studies have now been conducted for around 40 years or more. Given their relative inattention to context and difficulties in disentangling cause and effect it might be considered time for radical change to or even abandonment of such studies. However the longevity of the studies coupled with a growing programme of comparative research me...

Physical activity and pre-diabetes—an unacknowledged mid-life crisis: findings from NHANES 2003–2006

The prevalence of pre-diabetes (PD) among US adults has increased substantially over the past two decades. By current estimates, over 34% of US adults fall in the PD category, 84% of whom meet the American Diabetes Association's criteria for impaired fasting glucose (IFG). Low physical activity (PA) and/or sedentary behavior are key drivers of hyperglycemia. We examined the relationship between...

Thermohaline circulation crisis and impacts during the mid-Pleistocene transition.

The mid-Pleistocene transition (MPT) marked a fundamental change in glacial-interglacial periodicity, when it increased from ~41-thousand-year to 100-thousand-year cycles and developed higher-amplitude climate variability without substantial changes in the Milankovitch forcing. Here, we document, by using Nd isotopes, a major disruption of the ocean thermohaline circulation (THC) system during ...
