Fatal Haemorrhage from a Varicose Vein: A Case Report from 50 Years Ago

A 55-year old woman died of haemorrhage from a superficial varicose vein on her right leg. She had been in good health and had never been hospitalised. The author discusses the circumstances leading to this tragic event, which happened 50 years ago, and could have been avoided with simple measures. In fact, the actions taken by her relatives before they called for a doctor probably contributed to her death. A brief review of the literature describing such cases is included

Religious perspectives on human suffering: Implications for medicine and bioethics

The prevention and relief of suffering has long been a core medical concern. But while this is a laudable goal, some question whether medicine can, or should, aim for a world without pain, sadness, anxiety, despair or uncertainty. To explore these issues, we invited experts from six of the world’s major faith traditions to address the following question. Is there value in suffering? And is something lost in the prevention and/or relief of suffering? While each of the perspectives provided maintains that suffering should be alleviated and that medicine’s proper role is to prevent and relieve suffering by ethical means, it is also apparent that questions regarding the meaning and value of suffering are beyond the realm of medicine. These perspectives suggest that medicine and bioethics has much to gain from respectful consideration of religious discourse surrounding suffering. Keywords Suffering; religion; medicine; bioethic

Interacting mindreaders

Could interacting mindreaders be in a position to know things which they would be unable to know if they were manifestly passive observers? This paper argues that they could. Mindreading is sometimes reciprocal: the mindreader's target reciprocates by taking the mindreader as a target for mindreading. The paper explains how such reciprocity can significantly narrow the range of possible interpretations of behaviour where mindreaders are, or appear to be, in a position to interact. A consequence is that revisions and extensions are needed to standard theories of the evidential basis of mindreading. The view also has consequences for understanding how abilities to interact combined with comparatively simple forms of mindreading may explain the emergence, in evolution or development, of sophisticated forms of social cognition

Long-Term IGF-I Exposure Decreases Autophagy and Cell Viability

A reduction in IGF-I signaling has been found to increase lifespan in multiple organisms despite the fact that IGF-I is a trophic factor for many cell types and has been found to have protective effects against multiple forms of damage in acute settings. The increase in longevity seen in response to reduced IGF-I signaling suggests that there may be differences between the acute and chronic impact of IGF-I signaling. We have examined the possibility that long-term stimulation with IGF-I may have a negative impact at the cellular level using quiescent human fibroblasts. We find that fibroblast cells exposed to IGF-I for 14 days have reduced long-term viability as judged by colony forming assays, which is accompanied by an accumulation of senescent cells. In addition we observe an accumulation of cells with depolarized mitochondria and a reduction in autophagy in the long-term IGF-I treated cultures. An examination of mice with reduced IGF-I levels reveals evidence of enhanced autophagy and fibroblast cells derived from these mice have a larger mitochondrial mass relative to controls indicating that changes in mitochondrial turnover occurs in animals with reduced IGF-I. The results indicate that chronic IGF-I stimulation leads to mitochondrial dysfunction and reduced cell viability
