Eating while viewing TV may impair memory of food intake and promote over-consumption on a later meal. In Experiment 1, females ate a similar amount of snack-food either with or without TV. Later, participants who had snacked with TV ate more food on a TV-free lunch and were less accurate in recalling their earlier snack-food intake. Experiment 2 explored whether the nature of the TV content might alter these effects. Using a similar design, females watched boring, sad or funny TV, or no-TV at all. Relative to the no-TV control, all TV while snacking conditions ate a similarly greater amount on the later TV-free test lunch. Recall accuracy for the snack phase was also similarly poorer in all TV conditions. These findings suggest that eating with TV per se impacts on later food intake, and a mnemonic-based explanation seems to be the best account for these findings.
Extracorporeal life support has evolved to become a viable support option in patients with acute cardiac failure. Tailored mechanical circulatory support (MCS) can now be provided to patients using existing extracorporeal life support devices. 1 We report the successful use of peripheral venoarterial extracorporeal membrane oxygenation (ECMO) to provide MCS to a patient with acute 5-flurouracil (5-FU)-induced cardiomyopathy. 5-FU is a key component of adjuvant chemotherapy for colorectal cancer. It is also frequently used in the treatment of gastric, esophageal, pancreatic, breast, bladder, and prostate cancer. There is a wide range of cardiotoxicity with this 5-FU, including ischemia, vasospasm, arrhythmia, hypertension, Q-T interval prolongation, and acute cardiomyopathy and 5-FU-induced cardiac complications are not rare.2 This case illustrates the crucial place of ECMO as a bridge to recovery in chemotherapy, cardiomyopathy, or decision making. Case ReportA 32-year-old man began adjuvant treatment for colorectal adenocarcinoma with 5-FU continuous infusion after presumed curative bowel resection. He experienced stuttering chest pain from day 1 of therapy with progressive shortness of breath. His risk factors for cardiovascular disease included a positive family history of ischemic heart disease and previous methamphetamine use. He presented to the emergency department in a peripheral hospital on completion of his first cycle, where he was noted to be in paroxysmal atrial fibrillation with rapid ventricular response alternating with sinus tachycardia with inferolateral ST elevation. Cardiac troponin was mildly elevated and a presumptive diagnosis of 5-FU-induced cardiotoxicity was made. Sublingual glyceryl trinitrate, oral atenolol, and amlodipine were administered. After this, the patient became hypotensive, with cool and clammy peripheries. He was commenced on dobutamine and noradrenaline infusions and transferred to our center.Urgent cardiac catheterization confirmed angiographically normal coronary arteries (Figure 1). His left ventricular enddiastolic pressure was elevated at 30 mm Hg. An intra-aortic balloon pump was inserted through the left femoral artery. Transthoracic echocardiogram revealed severe global dysfunction with an ejection fraction of 10% to 15% with normal valves and no pericardial effusion. There was no evidence of significant dilation or thinning of ventricular chambers, thus inferring an acute and potentially reversible process (Figure 2).The patient was transferred to the intensive care unit with severe cardiogenic shock despite intra-aortic balloon counterpulsation and high doses of dobutamine (10 μg/kg per minute), noradrenaline (0.25 μg/kg per minute), and adrenaline (0.25 μg/kg per minute). There was evidence of end-organ malperfusion with increasing lactate, altered mentation, and early hepatic and renal dysfunction. In the face of impending circulatory collapse, peripheral venoarterial ECMO was instituted as a bridge to recovery. He was deemed unsuitable for cardiac transplanta...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
