What is POTS? And how is it related to long COVID?

What actually is palliative care? And how is it different to end-of-life care?

In fact, it can be a profound and positive form of care that the World Health Organization (WHO) has recognised as a basic human right. But what does it involve?

Immune cells that fight cancer become exhausted within hours of first encountering tumors – new research

A type of T cell called cytotoxic T cells can recognize the mutated proteins on cancer cells and should therefore be able to kill them. However, in most patients, cancer cells grow unchecked despite the presence of T cells.

The current explanation scientists have as to why T cells fail to eliminate cancer cells is because they become “exhausted.” The idea is that T cells initially function well when they first face off against cancer cells, but gradually lose their ability to kill the cancer cells after repeated encounters.

Australian study links holiday feasting to yo-yo weight gain

Easter, a time of chocolate eggs and hot cross buns, saw a an average gain of about 244g (0.29% of average participant body weight). The Australian summer months associated with Christmas and New Year, feasts and festivities, had an even larger average increase of approximately 546g (0.65% of average participant body weight). We also found a weekly cycle, with weight peaking on the weekend, when many people are likely letting their hair down after a busy work week and may be drinking and eating more.
