Brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. [5] BNP is one of the three natriuretic peptides, in addition to atrial natriuretic peptide and C-type natriuretic peptide ( CNP). [6]
There is no level of BNP that perfectly separates patients with and without heart failure. [14] In screening for congenital heart disease in pediatric patients, an NT-proBNP cut-off value of 91 pg/mL could differentiate an acyanotic heart disease (ACNHD) patient from a healthy patient with a sensitivity of 84% and specificity of 42%. [15]
Although the causes and existence of post-chemotherapy cognitive impairment have been a subject of debate, recent studies have confirmed that post-chemotherapy cognitive impairment is a real, measurable side effect of chemotherapy that appears in some patients. [3] While any cancer patient may experience temporary cognitive impairment while ...
Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.

However, it is an option only for patients with surgically resectable tumours; it cannot be used to treat DIPG. [22] Osmotic blood–brain barrier disruption (BBBD): The cells of the blood–brain barrier are shrunk by a concentrated sugar solution . This opens the barrier and allows 10 to 100 times more chemotherapy to enter the brain.
It can be due to direct injury to the brain, or illness remote from the brain. The individual findings that cause a clinician to refer to a person as having encephalopathy include intellectual disability, irritability, agitation, delirium, confusion, somnolence, stupor, coma and psychosis.
