cohort than in both arms of the ARRIVE trial (2.1 vs. 5.4% in the expectant group and 4.3% in the induction group). We did not record cases with an Apgar score ≤ 3 or hypoxic-ischemic encephalopathy.
In our cohort, expectant management in low-risk pregnancies with late preterm screening of feto-maternal well-being seemed to achieve better maternal and perinatal outcomes than a universal policy of induction at 39 weeks. read more The results of the ARRIVE trial should be carefully evaluated in different demographic and clinical settings and cannot be extended to the general population.

Due to a nationwide shortage of Ringer’s lactate, normal saline became the intravenous fluid of choice at our institution in May 2018. Recent studies have shown that the administration of normal saline in critically ill patients may have adverse renal effects.
Our objective was to evaluate the renal function effects; if any, of normal saline administered to women with preeclampsia receiving magnesium sulfate.
This is a prospective observational study of women identified with preeclampsia with severe features, requiring magnesium sulfate prophylaxis. The amount of normal saline administered was calculated and a basic metabolic panel was surveyed 12 h after initiation of magnesium sulfate prophylaxis. Laboratory analytes were examined according to the volume of intravenous normal saline received, including a comparison to those women who did not receive normal saline, to determine the impact of parameters after 12 h of magnesium sulfate prophylaxis.
From May 2018 to November 2018, a total of 233 patientRenal function indices were preserved despite the introduction of normal saline with oxytocin into routine practice. No dose-response relationship was identified when serum chloride and creatinine were analyzed across quartiles of normal saline received. Interestingly, serum calcium levels were noted to decline with both the amount of intravenous fluid received as well as with increasing serum magnesium levels.
To characterize the biometric parameters in ultrasound and brain MRI of fetuses with isolated mega cisterna magna (MCM).
Cross-sectional historical cohort study conducted at a single tertiary medical center between 2011 and 2018. All fetuses underwent US and brain MRI scans. Matching analysis was performed according to gender and gestational age.
The study included a total of 103 fetuses; 44 fetuses with isolated MCM in the study group, and a control group of 59 fetuses with normal CNS. The study group had larger biparietal diameter (BPD) (86 vs. 79.8 mm,
= .001) and head circumference (HC) (318 vs. 292 mm,
< .001) on ultrasound. On MRI, study group had larger occipitofrontal diameter (OFD) (99 vs. 92 mm,
< .001) and BPD (77 vs. 72 mm,
< .001). Male fetuses’ prevalence was higher in the study group (77.3% vs. 47.5%). After matching 20 fetuses from each group, the study group had larger HC (310.1 versus 300.7 mm,
= .029) and OFD (113.4 versus 108.3 mm,
= .009) on ultrasound, and larger OFD (97.4 versus 94.6,
= .013) on brain MRI.
Isolated MCM may be related to other large fetal CNS biometric measurements in both ultrasound and MRI and might be influenced by fetal gender.

Retrospective study at a unique center.
The aim of this study is twofold, to develop a virtual patients model for lumbar decompression surgery and to evaluate the precision of an artificial neural network (ANN) model designed to accurately predict the clinical outcomes of lumbar decompression surgery.
We performed a retrospective study of complete Electronic Health Records (EHR) to identify potential unfavorable criteria for spine surgery (predictors). A cohort of synthetics EHR was created to classify patients by surgical success (green zone) or partial failure (orange zone) using an Artificial Neural Network which screens all the available predictors.
In the actual cohort, we included 60 patients, with complete EHR allowing efficient analysis, 26 patients were in the orange zone (43.4%) and 34 were in the green zone (56.6%). The average positive criteria amount for actual patients was 8.62 for the green zone (SD+/- 3.09) and 10.92 for the orange zone (SD 3.38). The classifier (a neural network) was trained using 10,000 virtual patients and 2000 virtual patients were used for test purposes. The 12,000 virtual patients were generated from the 60 EHR, of which half were in the green zone and half in the orange zone. The model showed an accuracy of 72% and a ROC score of 0.78. The sensitivity was 0.885 and the specificity 0.59.
Our method can be used to predict a favorable patient to have lumbar decompression surgery. However, there is still a need to further develop its ability to analyze patients in the “failure of treatment” zone to offer precise management of patient health before spinal surgery.

Hymenin showed highest cytotoxic activity against HCT-116, A-549, and MCF-7 cell lines (IC50= 3.83 ± 0.2, 5.48 ± 0.3, 10.1 ± 0.6 µg/mL, respectively). Damsin has significant COX-2 inhibitory activity (IC50=33.97 ± 1.62 µg/mL) while hymenin showed highest selectivity to COX-1 (IC50 = 18.21 µg/mL) and significant inhibition of NO (IC50=18.19 ± 0.75 µg/mL). The docking study revealed nice fitting into COX-1/2 and a higher binding affinity for maritimolide towards human Src kinase compared to the native ligand, Bosutinib. Results suggested that both COXs/Src kinase inhibition could contribute even partially to the overall mechanism of cytotoxic activity of the five compounds. The structure-activity relationship revealed that α-methylene-γ-lactone moiety enhances the cytotoxic activity, OH group at C-1 increase activity of hymenin. However, the reduction of the double bond at C-2 as in damsin resulted in a significant decrease in activity against HCT-116 and MCF-7 cells.
