A Comparative Study of Ultrasmall Calcium Carbonate Nanoparticles for Targeting and Imaging Atherosclerotic Plaque
ACS Nano. 2023 Jul 3. doi: 10.1021/acsnano.3c03523. Online ahead of print.ABSTRACTAtherosclerosis is a complex disease that can lead to life-threatening events, such as myocardial infarction and ischemic stroke. Despite the severity of this disease, diagnosing plaque vulnerability remains challenging due to the lack of effective diagnostic tools. Conventional diagnostic protocols lack specificity and fail to predict the type of atherosclerotic lesion and the risk of plaque rupture. To address this issue, technologies are emerging, such as noninvasive medical imaging of atherosclerotic plaque with customized nanotechnologic...

Inflammation May Be the Culprit Behind Our Deadliest Diseases
In the early days of my medical residency, I met a man whom we’ll call Jason. He arrived to our emergency room on a holiday, nonchalant yet amiable, and complained of mild chest pain. Jason was tall and trim, with a strong South Boston accent and fingertips still faintly stained from his last home-improvement project. He was only 45 years old, but he looked much younger. He didn’t smoke, barely drank alcohol, and his cholesterol levels had always been normal. No one in his family had a history of heart disease. He asked us if we could work quickly—he wanted to be home for dinner with his daughters. [time-...

Stroke and cancer
Rev Neurol (Paris). 2023 Apr 4:S0035-3787(23)00891-3. doi: 10.1016/j.neurol.2023.03.009. Online ahead of print.ABSTRACTAssociation between stroke and cancer is well-established and has led to a growing literature over the past decades. Risk of ischemic and hemorrhagic stroke is increased among patients with newly diagnosed cancer and 5-10% of stroke patients bear an active cancer. All cancers are concerned, but hematological malignancy in childhood and adenocarcinoma from lung, digestive tract and pancreas in adults are most usually identified. Unique stroke mechanisms are dominated by hypercoagulation, a condition that ma...

Neuroimaging findings and neurological manifestations in hospitalized COVID-19 patients: Impact of cancer and ventilatory support status
This study suggests COVID-19 is associated with neurological manifestations that may be visible with brain imaging techniques such as MRI. In our COVID-19 cohort, there was no association between cancer status and neuroimaging findings. Future studies might include more prospectively enrolled systematically characterized patients, allowing for more rigorous statistical analysis.

A survey of deep learning for MRI brain tumor segmentation methods: Trends, challenges, and future directions
ConclusionThis review's objective is to increase scholars' interest in this difficult field and familiarize them with current advancements in it. To create CAD systems aimed at brain tumor identification using MR images, digital image processing approaches, such as preprocessing, segmentation, and classification, are applied. The classic machine learning and deep learning approaches for brain tumor identification are deliberated in this work. This paper provides a summary of commonly used MR image datasets. For classification, various machine learning and deep learning algorithms have been used. This survey examines curren...

How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss. Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

Analysis of Epidemiological Characteristics of New Cardiovascular Diseases in Cancer Patients with Cardiovascular Disease
J Oncol. 2022 Aug 31;2022:5157398. doi: 10.1155/2022/5157398. eCollection 2022.ABSTRACTIn cancer patients, a cardiovascular disease (CVD) is a prevalent occurrence. When a patient has both heart disease and cancer, the treatment can be complicated because treatment for one condition can have an adverse effect on the outcome of the other. A cardiovascular disease that involves heart failures, coronary artery disease (CAD), stroke, pericardial diseases, arrhythmias, and valve and vascular dysfunction is a serious worry for long-term cancer patients. Because preclinical research is limited, it is critical to comprehend the pa...

Assessing radiation-induced carotid vasculopathy using ultrasound after unilateral irradiation: a cross-sectional study
CONCLUSIONS: Increased CCA-IMT and SWV in some segments were seen in irradiated carotids. These alterations, even in young patients, mark the need for surveillance of radiation-induced vasculopathy.TRIAL REGISTRATION: clinicaltrials.gov ( https://clinicaltrials.gov/ct2/show/NCT04257968 ).PMID:35871069 | DOI:10.1186/s13014-022-02101-7
