Breast cancer (BC) is a global concern due to its high incidence worldwide. The alarming increase in BC cases highlights the need for careful management of disease at multiple levels. This study investigated diagnostic value hemoglobin, albumin, lymphocyte and platelet counts (HALP score), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte (PLR) lymphocyte-to-monocyte (LMR) newly diagnosed patients. A total 84 individuals, including 42 healthy volunteers (group I) patients with...

This study aimed to assess the predictive value of Diastolic Deceleration Area (DDA), a novel Doppler ultrasound parameter, in detecting adverse neonatal outcomes fetuses with late-onset fetal growth restriction (FGR). While parameters such as cerebroplacental ratio (CPR), umbilicocerebral (UCR), and cerebralplacentaluterine (CPUR) are commonly used for monitoring, their power varies. Given importance cerebral blood flow redistribution adaptation hypoxia, we investigated whether DDA could...
