Effects of high-energy photon beam radiation therapy on Jarvik 2000 LVAD: in vitro evaluation

ConclusionThe Jarvik 2000 resulted stable under direct X-ray beam of 10-MV energy. Its strong attenuation, however, can affect dose deposition in the pump in TPS, and it must be taken into account.

AbstractPurpose of ReviewCancer treatment –related cardiotoxicity (CTRC) represents a significant cause of morbidity and mortality worldwide. The purpose of our review is to summarize the epidemiology, natural history, and pathophysiology of cardiotoxicity-related to cancer treatment. We also summarize appropriate screening, surveillance, and management of CTRC. While cardiotoxicity is characteristically associated with anthracyclines, HER2-B antagonists, and radiation therapy (XRT), there is growing recognition of toxicity with immune checkpoint inhibitors (ICI), tyrosine kinase inhibitors, and proteasome inhibitors...

The field of medical AI is buzzing. More and more companies set the purpose to disrupt healthcare with the help of artificial intelligence. Given how fast these companies come and go, it can prove to be hard to stay up-to-date with the most promising ones. Here, I collected the biggest names currently on the market ranging from start-ups to tech giants to keep an eye on in the future. To further help you keep up with what A.I. brings to medicine, The Medical Futurist team made an easy-to-digest e-book about just that. I highly encourage you to read it and would love to hear about your thoughts! Artificial Intelligence has ...

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

Conclusions: The rate of asymptomatic LVEF decline in patients receiving concurrent trastuzumab and Hypo-RT was low (7%) and was similar to the rate observed in patients receiving Conv-RT. Longer follow-up is warranted to assess late cardiotoxicity.

AbstractA large intra-cardiac tumor from the right ventricle to pulmonary trunk was detected by contrast-enhanced computed tomography and transthoracic echocardiography in a 59-year-old woman with progressive dyspnea on effort and acute congestive right-sided heart failure. Emergent surgical management was performed with cardiopulmonary bypass under cardiac arrest, however, tumor resection was incomplete, because it originated from the interventricular septum. Concomitant tricuspid valve replacement using a bioprosthesis was required due to the involvement of the septal leaflet of the tricuspid valve. Although large pulmon...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

In this study, analysis of antioxidant defense was performed on the blood samples from 184 "aged" individuals aged 65-90+ years, and compared to the blood samples of 37 individuals just about at the beginning of aging, aged 55-59 years. Statistically significant decreases of Zn,Cu-superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were observed in elderly people in comparison with the control group. Moreover, an inverse correlation between the activities of SOD-1, CAT, and GSH-Px and the age of the examined persons was found. No age-related changes in glutathione reductas...

Opinion statementThe past 5 decades have seen significant improvements in outcomes for pediatric patients with cancer. Unfortunately, children and adolescents who have been treated for cancer are five to six times more likely to develop cardiovascular disease as a result of their therapies. Cardiovascular disease may manifest in a plethora of ways, from asymptomatic ventricular dysfunction to end-stage heart failure, hypertension, arrhythmia, valvular disease, early coronary artery disease, or peripheral vascular disease. A number of treatment modalities are implicated in pediatric and adult populations, including anthracy...
