OBJECTIVE: To assess the morbidity associated with continuing the second-stage duration of labor, weighing the probability of spontaneous vaginal birth without morbidity compared with birth with serious maternal or neonatal complications. METHODS: In a retrospective cohort, we analyzed singleton, vertex births at 36 weeks of gestation or greater without prior cesarean delivery (n=43,810 nulliparous and 59,605 multiparous women). We calculated rates of spontaneous vaginal birth and composite serious maternal or neonatal complications...

BACKGROUND: Persistently high rates of cesarean deliveries are cause for concern for physicians, patients, and health systems. Prelabor assessment might be refined by identifying factors that help predict an individual patient's risk of cesarean delivery. Such factors may contribute to patient safety and satisfaction as well as health system planning and resource allocation. In an earlier study, neonatal head circumference was shown to be more strongly associated with delivery mode and other outcome measures, than neonatal birth weight...

BACKGROUND: The dramatic rise in cesarean delivery (CD) rates worldwide in recent decades, without evidence of a concomitant decrease in cerebral palsy rates, has raised concerns about its potential negative consequences for maternal and infant health. In 2014, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine jointly published an Obstetric Care Consensus for safe prevention of the primary cesarean delivery. OBJECTIVE: We sought to assess whether modification of our protocol to implement these recommendations helped to decrease our primary CD rate safely...

BACKGROUND: Neonatal encephalopathy (NE) affects 2-4/1000 live births with outcomes ranging from negligible neurological deficits to severe neuromuscular dysfunction, cerebral palsy and death. Hypoxic ischemic encephalopathy (HIE) is the sub cohort of NE that appears to be driven by intrapartum events. Our objective was to identify antepartum and intrapartum factors associated with the development of neonatal HIE. METHODS: Hospital databases were searched using relevant diagnosis codes to identify infants with neonatal encephalopathy...

BACKGROUND: Postpartum fatigue is a very common complaint among postpartum women. Although current evidence indicates that several factors (e.g., parity, epidural analgesia, perineal trauma, perineal pain, and longer second stage of labor) are associated with postpartum, not enough is known about the relationships among these physical factors simultaneously and how they contribute to the development of postpartum fatigue. Increased awareness of the complex relationships among these factors will help nurses assess, prevent, and alleviate postpartum fatigue...

The main complication of diabetes is Diabetic retinopathy (DR), retinal vascular disease and it leads to the blindness. Regular screening for early DR disease detection is considered as an intensive labor and resource oriented task. Therefore, automatic detection of DR diseases is performed only by using the computational technique is the great solution. An automatic method is more reliable to determine the presence of an abnormality in Fundus images (FI) but, the classification process is poorly performed...

Episiotomy is obstetric procedure during which the incision extends the vestibule of the vagina during the second stage of labor. Episiotomy was extensively spread with gradual increase of rates in the first half of the 20th century and was performed medio-laterally in all nulliparous women with the idea to protect fetal head from trauma and pelvic floor from injuries. However, reports claiming that episiotomy had no such benefits were published. It was shown that routine medio-lateral episiotomy did not protect against the appearance of urinary incontinence after vaginal delivery, while the risk of anal incontinence could be increased...
