The impact of childhood parental quality on mental health outcomes in older adults.

OBJECTIVE: Parental bonding is cited as a determinant of mental health outcomes in childhood, adolescence and early-mid adulthood. Examination of the long-term impact for older adults is limited. We therefore examine the long-term risk of perceived poor parental bonding on mental health across the lifespan and into early-old age. METHODS: Participants (N = 1255) were aged 60-64 years of age and drawn from the Australian Life Histories and Health study. Quality of parental bonding was assessed with the Parental Bonding Instrument (PBI). Self-reported history of doctors' mental health diagnoses and current treatment for each participant was recorded. Current depression was assessed with the Centre for Epidemiologic Studies Depression-8 (CESD-8). Due to known gender differences in mental health rates across the lifespan, analyses were stratified by sex. RESULTS: A bi-factor analysis of the PBI in a structural equation framework indicated perceived Poor Parental Quality as a risk for both ever and current depression for both sexes. For males, Over-Protective Fathers were a risk for ever and current depression, whilst overall Poor Parental Quality was a risk for reporting current depression treatment. Whilst a number of the risks associated with current depression and treatment were attenuated when controlling for current mood, parental quality remained a significant risk for having reported a lifetime diagnosis for depression and anxiety for men. CONCLUSION: Our results extend the existing literature base and demonstrate that mental health risk attributed to poor perceived parental quality continues across the life-course and into early-old age.

Persistent organic pollutants and diabetes: a review of the epidemiological evidence.

The prevalence of diabetes and obesity has increased rapidly over the last few decades in both developed and developing countries. While it is intuitively appealing to suggest that lifestyle risk factors such as decreased physical activity and adoption of poor diets can explain much of the increase, the evidence to support this is poor. Given this, there has been an impetus to look more widely than traditional lifestyle and biomedical risk factors, especially those risk factors, which arise from the environment. Since the industrial revolution, there has been an introduction of many chemicals into our environment, which have now become environmental pollutants. There has been growing interest in one key class of environmental pollutants known as persistent organic pollutants (POPs) and their potential role in the development of diabetes. This review will summarise and appraise the current epidemiological evidence relating POPs to diabetes and highlight gaps and flaws in this evidence.

The head-up tilt test -- a cause of myocardial infarction.

INFARCTION: A 74-year-old man with no known ischaemic heart disease presented to the Cardiology Department with a history of multiple episodes of pre-syncope. During a head-up tilt test to investigate a neurocardiogenic cause, after glyceryl trinitrate provocation he became profoundly hypotensive and unwell. Subsequent ECGs and Troponin-T levels confirmed a Non ST-Elevation Myocardial Infarction. Angiography confirmed coronary artery disease. This case highlights a rare complication of tilt testing and emphasises that the test is not without risk.
