Meta Analysis
Effect of Sleeve Gastrectomy on Ghrelin, GLP-1, PYY, and GIP Gut Hormones: A Systematic Review and Meta-analysis.
To perform a structured systematic review and meta-analysis to evaluate changes in ghrelin, glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and gastric inhibitory peptide (GIP) gut hormone levels in patients after sleeve gastrectomy. ⋯ Fasting ghrelin levels decreased, whereas postprandial GLP-1 and PYY increased after sleeve gastrectomy. Fasting GIP levels remained unchanged. Future studies are needed to assess the role of these gut hormones and relationship to weight loss and metabolic outcomes.

Unspecified kidney donation (UKD) describes living donation of a kidney to a stranger. The practice is playing an increasingly important role within the transplant programme in the United Kingdom, where these donors are commonly used to trigger a chain of transplants; thereby amplifying the benefit derived from their donation. The initial reluctance to accept UKD was in part due to uncertainty about donor motivations and whether the practice was morally and ethically acceptable. ⋯ We believe UKD is an ethically acceptable practice which should continue to grow, despite its controversies. In our experience, these donors are primarily motivated by a desire to help others and utilization of their kidney as part of a sharing scheme means that many more people seek to benefit from their very generous donation.
