Resolution of severe hyponatraemia is associated with improved survival in patients with cancer

© Balachandran et al.Background: Hyponatraemia is a common finding in patients with cancer, and has been shown to be associated with poor prognosis in different settings. We have analysed the impact of severe hyponatraemia in patients with cancer. Methods: A retrospective review of all patients admitted to a specialist cancer hospital with a plasma sodium of less than 115 mmol/l and a diagnosis of malignancy was undertaken. Patient and tumour characteristics were analysed as well as impact of hyponatraemia management on overall survival and number of lines of cancer treatment received. Results: 57 patients were identified. 84% had advanced Stage 3 or 4 cancer and approximately 85% with data available had symptoms attributable to hyponatraemia. Mean length of hospital stay was 12 days, and overall survival (OS) was 5.1 months. Plasma sodium level corrected in 56% of patients and here OS was 13.6 months compared to 16 days in those whose sodium did not correct (p < 0.001). Those whose sodium corrected were more likely to receive further lines of anti-cancer treatment. Conclusions: Severe hyponatraemia in cancer is associated with very poor survival, but correction of the sodium level leads to additional treatment and significantly greater overall survival (although it is not possible to determine if this is due to specific therapy of the hyponatraemia or the resolving hyponatraemia reflects an improvement in the clinical condition). Aggressive treatment of hyponatraemia may allow more anti-cancer treatment and improve survival

Histologically proven myocardial carcinoid metastases: the value of multimodality imaging

We present a case of a patient with intramyocardial metastases from a carcinoid tumor. These findings were detected using cardiovascular magnetic resonance imaging, with functional metabolic activity analyzed using nuclear imaging and confirmed by histologic findings at surgical biopsy. This case highlights the value of cardiovascular magnetic resonance imaging and the importance of multimodality imaging

A functional interaction between RIP140 and PGC-1α regulates the expression of the lipid droplet protein CIDEA

Nuclear receptors activate or repress target genes depending on the recruitment of coactivators or corepressors. The corepressor RIP140 and the PPAR coactivator 1α (PGC-1α) both play key roles in the regulated transcription of genes involved in energy homeostasis. We investigated the roles of RIP140 and PGC-1α in controlling the expression of CIDEA, an important regulatory factor in adipose cell function and obesity. Ectopically expressed CIDEA surrounded lipid droplets in brown adipocytes and induced the formation of lipid droplets in nonadipogenic cell lines. The expression and promoter activity of CIDEA was repressed by RIP140 and induced by PGC-1α, mediated through the binding of estrogen-related receptor α and NRF-1 to their cognate binding sites. Importantly, we demonstrate that RIP140 interacts directly with PGC-1α and suppresses its activity. The direct antagonism of PGC-1α by RIP140 provides a mechanism for regulating target gene transcription via nuclear receptor-dependent and -independent pathways
