Background: The objective was to determine the effectiveness of Doppler velocimetry results in the management of high-risk pregnancy.
Materials And Methods: This cohort study was conducted from January 2005 to December 2006 in Obstetrics and Gynecology Department of Alnoor Specialist Hospital, Makkah, Saudi Arabia. A total of 200 high-risk pregnant women with gestational age >28 weeks were selected for the study and divided into group A (100) subjected to Doppler velocimetry and group B (100) without Doppler velocimetry. Standard management protocols were followed in all cases. The primary outcome measures were mode of delivery and gestational age at the time of delivery. The secondary outcome measures were prenatal and neonatal complications. Data were analyzed using SPSS version 16 (SPSS Inc., Chicago, IL, USA).
Results: Preterm deliveries, preterm as well as full-term neonatal admissions were more frequent in group A than those in group B, i.e., (39% vs. 26%), (56% vs. 88%) (OR 0.2, 95% CI 0.04-0.7), and (30% vs. 57%) (OR 0.3, 95% CI 0.2-0.7), respectively. Similarly preterm and full-term neonatal deaths were rare in group A than those in group B, i.e., (9% vs. 78%) (OR 0.1, 95% CI 0.02-0.7), and (6% vs. 29%) (OR 0.2, 95% CI 0.03-1.8), respectively. Emergency caesarean section rate was rare in the subjects with normal Doppler than those with abnormal Doppler (48% vs. 100%) (OR 0.1, 95% CI 0.03-0.4) as well as in group B (48% vs. 82%) (OR 0.2, 95% CI 0.1-0.4).
Conclusion: Doppler studies in high-risk pregnancies are more beneficial in the management of perinatal as well as neonatal management.

Objective: Evaluation of the effectiveness of vestibuloplasty according to microhemodynamics and oxygenation in the mucous membrane of the alveolar ridge.
Materials And Methods: To achieve this goal, a clinical and functional study was carried out in the mucous membrane of the alveolar ridge after vestibuloplasty in 80 patients (35 men and 45 women) aged from 18 to 65 years, average age 41.5±1.
Objective: To analyze the dynamics of the condition of the mucous membrane in patients with metabolic syndrome at the stage of preparation for dental prosthetics using dental implants.
Material And Methods: 255 patients (151 women and 104 men) aged from 35 to 65 years were examined. 3 groups were formed: 2 study groups and a comparison group.

Objective: The objective of this study was to conduct a longitudinal assessment of inter-twin growth and Doppler discordance, to identify possible distinct patterns, and to investigate the predictive value of longitudinal discordance patterns for adverse perinatal outcomes in twin pregnancies.
Methods: This retrospective cohort study included twin pregnancies followed and delivered at a tertiary University Hospital in London (UK), between 2010 and 2023. We included pregnancies with at least three ultrasound assessments after 18 weeks and delivery after 34 weeks' gestation.

In preeclampsia, there occurs a defective trophoblastic invasion of spiral arteries, which is characterized by abnormal uterine artery wave parameter such as increased pulsatility index (PI) and early diastolic notch. This increased uterine artery PI is a good predictor of hypertensive disorder and small for gestational-age babies. Maternal hypertension and proteinuria resolve in the puerperium.

We present a technique called photoacoustic vector-flow (PAVF) to quantify the speed and direction of flowing optical absorbers at each pixel from acoustic-resolution PA images. By varying the receiving angle at each pixel in post-processing, we obtain multiple estimates of the phase difference between consecutive frames. These are used to solve the overdetermined photoacoustic Doppler equation with a least-squares approach to estimate a velocity vector at each pixel.
