Is congestive heart failure a risk factor for venous thromboembolism in bariatric surgery?
CHF is a significant risk factor for VTE in bariatric surgery. Surgeons should consider aggressive screening and VTE prophylaxis in patients with CHF and other known risk factors to decrease postoperative morbidity from VTE.
In conclusion, immunological factors may play a hitherto underestimated role in suicide. First, microglial activation might be interpreted as a consequence of presuicidal stress. Second, one might speculate a causal link between microglial activation and suicidal behaviour, such as neuroendocrine factors, cytokines, and nitric oxide, which are released from microglial cells and are known to modulate noradrenergic or serotonergic neurotransmission and thus may trigger suicidality.
