No full textBackground:
Pregnancy is the physiological process in a woman's reproductive life. Though all pregnancies carry a risk, almost all pregnancies go uneventfully. In normal pregnancy, as the gestation advances, there is a physiological rise in triglycerides and cholesterol. Hypertriglyceridemia and hypercholesterolemia are markers of preterm labor, as atherosis of uteroplacental spiral arteries can result in preterm labor.
Aims & objectives:
To evaluate the correlation of increased levels of fats in uncomplicated gestation with preterm delivery
Materials & methods:
An observational study was conducted prospectively in the Department of Obstetrics & Gynaecology in Sree Balaji Medical College & Hospital, Chennai from Jan 2021 to July 2022, which included all Antenatal women between 14 to 32 weeks with no complications and who are planning to deliver in SBMCH.
Results:
Out of 290 Pregnant Women, 90.7% delivered at full term, whereas 9.3% had preterm deliveries. 12% had high serum cholesterol levels & 7.5% of them had hypertriglyceridemia. In this study, women who had preterm deliveries had elevated levels of lipids such as LDL and triglycerides, which is statistically significant.
Conclusion:
Early births are connected with high neonatal and infant mortality. According to statistical analysis of this study, women with intermediate or higher total, LDL, and triglyceride levels were more likely to deliver before 37 weeks of gestation than those with normal lipid profiles. Pregnancy dyslipidemia was also linked to BMI > 25 kg/m2 and advanced age.
Recommendation:
Based on these observations, we could recommend routine lipid profile assessment and management of dyslipidemia during pregnancy and in those planning to conceive, especially in relatively older women and those with obesity
Security Enhanced Clustering Scheme for Routing in Cognitive Radio Sensor Networks
No full textDue to the scarcity of wireless spectrum, it entails the utilization of dynamic shared spectrum solutions, which can be availed with an intelligent wireless communication technology called Cognitive Radio (CR). Wireless sensor nodes equipped with CR reconfigure dynamically to utilize the vacant spectrum holes, forming a Cognitive Radio Sensor Network (CRSN), which has high demand in Internet of Things (IoT) applications. Despite of attaining high spectrum utilization via CR capabilities, CR based sensor networks require energy efficient solutions due to their resource-constrained behavior. Therefore, a clustered architecture becomes suitable for maintaining opportunistically available radio resources and energy efficiency in CRSNs. In this paper, a trust-based secure clustering scheme is introduced for routing in CRSNs, where both direct and indirect/recommended trust are considered, along with an aging method for updating trust. This scheme accumulates the history of trust values to detect and eliminate malicious nodes from the network. Additionally, during cluster formation, two parameters weight value and neighbor set of each node are taken into consideration. These parameters are obtained through the suggested neighbor selection scheme. The neighbor selection approach considers the neighbor’s requirements in terms of transmission time and the availability of a common channel between the Cognitive Sensor (CS) node and the associated neighbor set. Thereafter, the proposed secure clustering approach will incorporate cluster head rotation to ensure an even distribution of energy consumption among the nodes in a cluster. Simulation based study demonstrates that the proposed scheme enhances detection efficiency, detection ratio, the network’s relative average packet delivery ratio, relative average packet drop ratio, average end-to-end delay, and average energy consumption of the network for selective forwarding, blackhole, and ON-OFF attacks in comparison with an existing method. Moreover, the correctness of the proposed scheme is evaluated in terms of precision and F1-Score
