Second Trimester Antenatal Umbilical Coiling Index and Its Doppler Flow Characteristics and Perinatal Outcome: A Prospective study

OBJECTIVE: To study correlation between antenatal Umbilical Cord Coiling Index (UCI) and umbilical vein blood flow and perinatal outcome. METHODS: UCI and umbilical vein blood flow were determined in 200 antenatal women with by ultrasonography and colour doppler between 20 to 28 weeks gestation. Results were correlated with following factors: gestational age of delivery, mode of delivery, meconium stained liquor, abnormal heart rate, birth weight, APGAR score and statistically analysed by Chi-square test. RESULTS: Hypocoiling was associated with preterm deliveries, LBW, low APGAR, abnormal heart rate and NICU admissions. Hypercoiling was associated with SGA, caesarean sections, meconium staining of liquor, low APGAR and NICU admissions. Increased umbilical vein blood flow was associated with SGA, meconium stained liquor and abnormal foetal heart rate. Decreased umbilical vein blood flow was associated with preterm deliveries, low birth weight, low APGAR. Positive correlation was observed between UCI and umbilical vein blood flow. UCI and umbilical vein blood flow also had positive correlation with birth weight and low APGAR. CONCLUSION: Abnormal coiling and abnormal umbilical vein blood flow can be used as a predictor of birth weight and low APGAR

IMPLEMENTATION OF MODEL PREDICTIVE CONTROL AND AUTO TUNING BASED PID FOR EFFECTIVE TEMPERATURE CONTROL IN CSTR

Continuous Stirrer Tank Reactor (CSTR) is an important topic in process control and offering a diverse range of researches in the area of chemical and control engineering. A simulation on mathematical model has several advantages over the experiment on a real model or system, which is used for steady state analysis and dynamic state analysis. The main objective is to control the temperature of CSTR in the presence of disturbance. Various control approaches have been applied on CSTR to control its parameters through PID control and MODEL PREDICTIVE CONTROL (MPC). Model design and simulation are done in MATLAB SIMULIN

Coronary Sinus to Left Atrial Communication

Congenital coronary sinus anomalies are rare in clinical practice, partly due to the lack of symptoms. We present a case of coronary sinus anomaly causing a right-to-left intracardiac shunt in a 46 years/old African American female with a past medical history of obstructive sleep apnea, diabetes mellitus, hypertension, coronary artery disease, and ischemic cardiomyopathy who presented with hypoxia. In the months prior to her presentation, she had suffered an inferior myocardial infarction with right ventricular involvement, as well as resulting severe tricuspid regurgitation. In conclusion, further investigations revealed a communication between the coronary sinus (CS) and left atrium (LA)

CYTO-HISTOLOGICAL CORRELATION OF BRONCHIAL BRUSH AND BRONCHIAL BIOPSY IN LUNG MALIGNANCIES

BACKGROUND:Lung cancer is one of the most common cancer and cause of cancer related deaths in about 29% of males and 26% of females all over the world. Fiberoptic bronchoscopy has an excellent result in diagnosis of lung cancer when combined with brushing cytology and biopsy. The Aim of the study is to correlate AIM: cytological and histological ndings in diagnosing lung carcinomas. This study was done in Department of Pathology, Government General MATERIALS AND METHODS: and Chest Hospital, Erragada, Hyderabad, Telangana from June 2018 to May 2020. 240 clinically suspected cases of lung malignancies underwent both bronchial brush and bronchial biopsy and were included in this study.RESULTS: Out of 240 cases, malignancy was conrmed in 194 cases by histopathology of bronchial biopsy, in which 152 cases were well correlated with brush cytology. Bronchial brush cytology showed sensitivity of 78.35% , specicity of 100% and accuracy of 82.5%. Bronchial biopsy has better detection rate t CONCLUSION han bronchial brush cytology in this study. However combination of brush cytology and biopsy can be considered as the best procedures for the diagnosis of lung malignancies.</jats:p
