Abstract

Background: The preeclampsia/eclampsia is one of the most serious condition peculiar to pregnancy, which defined as occurrence of hypertension, proteinuria in pregnancy and convulsion in eclamptic women. There are major risk for eclamptic and pre eclamptic women due to maternal and fetal complications.

Materials and Methods: In a prospective study, preeclamptic and eclamptic patients who were visited at Shariati hospital were divided into two groups due to having proper prenatal care or not. Maternal and fetal complication were studied in that two group. Maternal variables were included: incidence of preterm labor, eclampsia, mode of delivery, long term hospitalization, need for ICU, need to antihypertensive drugs over postportum, insistence of hypertension up to 6 weeks, postpartum trombocytosis, incidence of cesarean section due to abruptio placenta and IUGR, elevation of serum creatinine, incidence of HELLP syndrome and death of mother fetal variables were included incidence of IUGR and IUFD, pre term delivery and for need NICU. Relationship of demographic characteristics such as maternal age, parity, educational level, mode of delivery, presence of underlying disease, and educational level of person who referred the patient were studied.

Results: These variables except of educational level, and referral level were there was statistically significant difference between incidence of all of variables, in exception of mode of delivery. That means incidence of complications is lower in group with adequate prenatal care. Conclusion: It seems that adequate pernatal care can reduce or obligate maternal and fetal complication in hypertensive disorders in pregnancy.

Abstract

Background: Nuclear medicine imaging has shown high accuracy in evaluating the metabolism of colon cancer lesions. The aim of this study was to investigate the ability of radiomics features extracted from nuclear medicine images as non-invasive biomarkers of lesion metabolism in patients with colon cancer by examining the correlation of these features with SUV (standardized uptake value) max values.
Methods: The current study was a cross-sectional study that was conducted from July 2022 to July 2023 in the nuclear medicine department of Tehran University of Medical Sciences. In this study, PET/CT (positron emission tomography/computed tomography) images of 60 patients with primary colon cancer were used. Colon cancer lesions were manually delineated on PET images by an experienced physician and saved as VOIs (volumes of interest). Thirty-two textural radiomics features were extracted from each VOI, including feature groups of gray-level co-occurrence matrix (GLCM), gray-level run-length matrix (GLRLM), neighborhood grey-level difference matrix (NGLDM), and gray-level zone length matrix (GLZLM). Then, the correlation of these features with SUVmax values was investigated using the Spearman correlation coefficient statistical test. Also, the value of p<0.05 was considered as the significance level of the test.
Results: A comprehensive analysis revealed that more than 96% of the examined radiomics features specifically, 31 out of 32 exhibited a statistically significant correlation with lesion metabolism values, as indicated by p-values less than 0.05. Among these features, GLZLM_HGZE stood out with a high correlation coefficient of 0.9881, alongside a significance level of less than 0.0001. Similarly, GLZLM_SZHGE also demonstrated a strong correlation, with a coefficient of 0.9723 and a significance level below 0.0001, indicating a robust relationship with SUVmax values. In contrast, GLZLM_LZHGE was the only feature that failed to show a significant correlation with lesion metabolism values (p>0.05).
Conclusion: The radiomics method has the potential to be used as a completely non-invasive method to evaluate the metabolism of colon cancer lesions and facilitate the monitoring and treatment of patients with colon cancer.
