{"title":"Death and taxes: Lactate and the Laffer curve","authors":"Rose D. Nolen-Walston, Michael J. Mandel","doi":"10.1111/vcp.13387","DOIUrl":"10.1111/vcp.13387","url":null,"abstract":"<p>In 1980, Ronald Reagan was elected as a president on a simple platform: the need for tax cuts to revive the economy, which was struggling at the time. His theory, and the theory of the supply-side economists who supported him, was simple. Business owners are more likely to hire new workers and invest in new equipment if their after-tax income goes up. The supply-siders of the day believed that if federal tax rates were cut, especially at the top end, business owners would expand, boosting both employment and investment, increasing growth, and potentially even reducing inflation, which was a big problem at the time. Thus, the benefits of the tax cut would “trickle down” to all Americans. One of the main proponents of this theory was an economist called Arthur Laffer, who, in 1974, had been enjoying a late-night supper with a few Republican policy wonks (including Dick Cheney and Donald Rumsfeld, as it happened). The topic of conversation was tax rate and government income and whether President Ford's tax hikes would spur increases in federal revenue. Not necessarily, suggested Laffer, who reportedly whipped out a pen and made the following sketch on his napkin (Figure 1).<span><sup>1</sup></span>\u0000 </p><p>On the x-axis, we see tax rates ranging from 0% to 100%, and on the y-axis, there is government revenue. It is clear that a tax rate of 0% results in zero income, and the coffers are dry. Conversely, though, Laffer pointed out that a tax rate of 100% would result in the same thing. If the government takes every cent of your salary, you are clearly not going to work at all. So, what if, suggests Laffer's curve, we are here, point A in Figure 2, on the tax curve?</p><p>In this case, high tax rates are actually suppressing taxpayer's capitalist urges. A reduction in the tax rate to point B will paradoxically result in an increase in revenue, not a decrease, as shown here in Figure 3.</p><p>This was an odd thought. Could a drop in the tax rate really increase the amount of money the government collected? We avoid political commentary and allow readers their own interpretation of history as to the results of this experiment.<span><sup>2</sup></span> However, this concept has an interesting application in the consideration of physiology.</p><p>Take lactate, for example. L-lactate is produced by the mammalian cell as a product of anaerobic metabolism,<span><sup>3</sup></span> and is often used clinically as a measure of tissue perfusion. Blood lactate concentration not only assesses both the rate of production as well as clearance,<span><sup>4</sup></span> but also, in the very end, it is limited by the capacity of the heart and peripheral vasculature to mobilize the tissue-produced lactate and carry venous blood back to the sampling point. As such, lactate acts as the scorecard of the body; though blood lactate levels cannot tell you what is wrong or how to fix it, it provides useful information to clinicians as to whether they are winning","PeriodicalId":23593,"journal":{"name":"Veterinary clinical pathology","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/vcp.13387","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142308623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hematologic assessment revealed nonregenerative anemia, thrombocytopenia, and high numbers of neoplastic mononuclear cells with a variable degree of maturation. The mononuclear neoplastic cells, with nuclei measuring 10–20 microns in diameter, accounted for 57% of the nucleated blood cells. In addition, the blood contained increased numbers of mature neutrophils and monocytes with atypical morphology. Cytologic examination of the right popliteal lymph node found high numbers of large mononuclear cells with similar morphology to those in the peripheral blood. Flow cytometry of peripheral blood revealed expression by the mononuclear neoplastic cells of the pan‐leukocyte marker CD45 and myeloid markers CD14, MAC387, and myeloperoxidase (MPO). These results confirmed a diagnosis of acute myeloid leukemia (AML). Computed tomography found moderate nodular hepatosplenomegaly and multifocal bi‐cavitary lymphadenopathy. Histopathologic examination of biopsies from the cutaneous lesions identified infiltration of the dermis by intermediate to large neoplastic round cells. Further treatment was declined, and the owners elected euthanasia. Postmortem examination confirmed AML involvement in the bone marrow, peripheral and intracavitary lymph nodes, heart, liver, kidney, and skin.
