How we do it: evaluation of dyspnea and exercise intolerance after acute pulmonary embolism
Chest. 2022 Jul 2:S0012-3692(22)01215-6. doi: 10.1016/j.chest.2022.06.036. Online ahead of print.ABSTRACTLong-term dyspnea and exercise intolerance are common clinical problems after acute PE. Unfortunately, no single test can distinguish among the range of potential pathological outcomes after PE. We illustrate a stepwise approach to post-PE evaluation that uses a hierarchical series of clinically validated diagnostic tests. The algorithm is represented by the acronym SEARCH, which stands for symptom screening, exercise testing, arterial perfusion, resting echocardiography, confirmatory chest imaging and (right) heart cat...

Intracranial pressure: current perspectives on physiology and monitoring
AbstractIntracranial pressure (ICP) monitoring is now viewed as integral to the clinical care of many life-threatening brain insults, such as severe traumatic brain injury, subarachnoid hemorrhage, and malignant stroke. It serves to warn of expanding intracranial mass lesions, to prevent or treat herniation events as well as pressure elevation which impedes nutrient delivery to the brain. It facilitates the calculation of cerebral perfusion pressure (CPP) and the estimation of cerebrovascular autoregulatory status. Despite advancements in our knowledge emanating from a half century of experience with this technology, impor...

Is there a role of proinflammatory cytokines on degenerin ‐mediated cerebrovascular function in preeclampsia?
This brief review summarises studies showing the effect of proinflammatory cytokines on vascular degenerin expression and cerebral blood flow autoregulation to the pathological cerebral consequences of preeclampsia. We propose a mechanism by which cytokines may inhibit one autoregulatory mechanism, referred to as myogenic, or pressure induced, vasoconstriction, which is a common mechanism underlying the cerebrovascular disorders of preeclampsia. AbstractPreeclampsia (PE) is associated with adverse cerebrovascular effects during and following parturition including stroke, small vessel disease, and vascular dementia. A poten...

Expanded Criteria Donors
Exp Clin Transplant. 2022 Aug;20(Suppl 4):13-19. doi: 10.6002/ect.DonorSymp.2022.L13.ABSTRACTThe expanded criteria donor is any donor over the age of 60 years or a donor over the age of 50 years with 2 of the following 3 items: (1) history of high blood pressure, (2) serum creatinine ≥1.5 mg/dL, and (3) death due to stroke. To accept an expanded criteria donor kidney may significantly decrease the amount of time a person waits for transplant but requires written informed consent from the recipient. Although expanded criteria donor kidneys have predictably shorter outcomes than standard criteria donors, the exact risk is ...
