Does vitamin D cut lung infection risk in older adults?

Conclusion This randomised controlled trial assessed high dose supplementation with vitamin D for a period of 12 months as a way of preventing acute respiratory infections in older adults in long term care. This study was well designed and reduced risk of bias where possible. However, there are some important limitations which affect the reliability of the findings: The study has a small sample size and the authors state they did not manage to reach their target recruitment level; this means the study did not have the statistical power required for certainty in the findings. There were some differences in the characteristics of the participants at the start of the study, including differences in body mass index, smoking status, heart disease and respiratory diseases. Ideally, differences of these types should be minimised in a randomised study. But they were present in this case – possibly as a result of the small sample size – and may have affected findings. The study only included participants who are in long term care and this may not be representative of the effect in all older adults, including those with serious illnesses or contraindications to taking high doses of vitamin D. The study did appear to find that supplementation reduced the chance of respiratory events – though this seemed only due to a reduction in upper respiratory infections such as coughs and colds rather than more serious infections. It didn't find the increased dos...

AM Abstract Adoptive transfer of T cells transgenic for tumor-reactive T-cell receptors (TCR) is an attractive immunotherapeutic approach. However, clinical translation is so far limited due to challenges in the identification of suitable target antigens as well as TCRs that are concurrent safe and efficient. Definition of key characteristics relevant for effective and specific tumor rejection is essential to improve current TCR-based adoptive T-cell immunotherapies. We here characterized in-depth two TCRs derived from the human leukocyte antigen (HLA)-mismatched allogeneic repertoire targeting two different myel...

Obesity and alcohol consumption have been identified as two modifiable risk factors for breast cancer, while physical activity may offer protection. Little however is known abo...

Introduction: The gold standard for unresectable solid tumours and advanced forms of leukemia is represented by chemo-radiation. However, therapeutic options are limited and patients undergo systemic cytotoxicity. Vitamin D insufficiency is a widespread problem and its low serum levels are linked to higher cancer incidence. Previous studies showed a strong correlation between serum concentration of vitamin D and time of first treatment in chronic lymphocytic leukemia (CLL). Other studies demonstrated that vitamin D and its ipocalcemic analogue EB1089 are able to bypass radio-resistance in breast and lung cancer cell lines ...
