Prospective observational study to evaluate the efficacy of labetalol versus nifedipine in the management of preeclampsia

Background: Hypertensive disorders of pregnancy are the common medical disorders in pregnancy. It has effects both on expectant mother and fetus. Pre-eclampsia is a pregnancy specific multisystem disorder of unknown etiology, and accounts for 12-18% of maternal mortality. There is general consensus that maternal risk is decreased by antihypertensive treatment that lowers very high blood pressure. Objective of this study was to study the efficacy of oral labetalol versus oral Nifedipine in the management of preeclampsia in the antepartum and intrapartum period.Methods: The present study was conducted in a tertiary care centre, Chennai from October 2013 to September 2014. It was a prospective observational study done in antenatal ward and labor ward. All antenatal women diagnosed to have pre-eclampsia, irrespective of gestation are included in this study.Results: Age distribution of PIH patients and the maximum number of patients were 20-25 years of age. maximum patients of severe preeclampsia were primigravida. Both systolic and diastolic BP in the two groups (oral labetalol and oral Nifedipine groups) were not statistically significant as the p value is >0.005.Conclusions: From this study, authors found that both oral labetalol and oral nifedipine are effective and well tolerated when used for rapid control of blood pressure in severe hypertension of pregnancy

End to End Encrypted Smart Lock Using RSA based on Opinion from Social Media Review Comments

In the modern era, from big apartments to small houses, startups to corporate buildings, protecting assets or preventing unauthorized persons are crucial problems. Often traditional locks like padlocks are prone to security risks since they can be easily bypassed. Existing smart lock systems are prone to Man in middle Attacks where digital keys can easily be duplicated. The review comments about prevailing smart locks technologies have been collected from various sources such as blogs and microblogs.  The data set is analyzed to discover the opinion of the people about the smartlock product. In this proposed system, an innovative smartlock system prototype is designed using current technologies. A smart lock system has been proposed which is encrypted end-to-end using the RSA algorithm. This system uses a one-time password sent to registered users combined with the master code to unlock the door. This system is designed as such only the users who are connected to a wireless local area network are able to access the smart lock system, this adds an additional layer of security. It is connected to the cloud and logs all the activity from booting to shutting down. The breach detection system along with image capture is also included to detect forced intrusions. The client functionality can be easily ported to any platform which supports HTTP protocol which tends to be the major advantage of the proposed work
