knowledge about the clinical significance of v-raf murine sarcoma viral oncogene homolog b1 ( braf ) mutations in colorectal cancer (crc) is growing. braf encodes a protein kinase involved with intracellular signaling and cell division. the gene product is a downstream effector of kirsten ras 1( kras ) within the ras/raf/mapk cellular signaling pathway. evidence suggests that braf mutations, li...

INTRODUCTION Several studies evaluated the relation between colorectal cancer prognosis and various factors such as: depth of tumor invasion, involved lymph nodes size, counts and locations, metastatic nest expansion. We assessed the prognostic significance of the ratio between metastatic nest and involved lymph node diameter in colorectal cancer cases. METHODS A historical cohort study was c...

procalcitonin is widely used as a biomarker for diagnosis and prognosis for sepsis and infection as well as monitoring the response to antibiotic therapy. in this study we systematically reviewed the value of procalcitonin in diagnosis, treatment, and prognosis in patients with sepsis or infection.

Background: Asphyxia is one of the main causes of infant mortality and long-term neurologic complications. This cohort study was aimed to compare the diagnostic value of the hematologic and biochemical factors in prediction of prognosis of asphyxia according to the high prevalence of asphyxia and its complications. Methods: In this cohort with two-year follow up study with availability samplin...

BACKGROUND Obtaining an accurate understanding of a child's cancer prognosis can help parents make informed decisions about treatment. Research has shown that parents tend to overestimate their child's cancer prognosis relative to physicians. Thus, we examined whether the content of physician communication, parent sources of medical information, and parent demographic factors affected the assoc...

Cancer prognosis prediction is typically carried out without integrating scientific knowledge available on genomic pathways, the effect of drugs on cell dynamics, or modeling mutations in the population. Recent work addresses some of these problems by formulating an uncertainty class of Boolean regulatory models for abnormal gene regulation, assigning prognosis scores to each network based on i...
