In response to maternal deaths being three-fold higher for black.women than other races in New York.City, Governor Andrew M. Cuomo created a task.orce which met for a year. In March 2019, the task.orce published ten recommendations to address the current healthcare disparities. The task.orce recommended utilizing medical simulation training to improve sk.lls and communication. Peer-reviewed literature was explored for evidentiary support for embedding a simulation program in a NYC public hospital. In addition, obstacles to and advantages of in-situ simulation programs were discussed. Steps for garnering executive leadership support, improving teamwork. defining outcome measures, and identifying beneficiaries of in-situ simulation programs were explored.

AIM： To investigate the proximal gastric motor response to duodenal nutrients in critically ill patients with longstanding type 2 diabetes ***： Proximal gastric motility was assessed （using a barostat） in 10 critically ill patients with type 2 diabetes mellitus （59±3 years） during two 60-min duodenal infusions of Ensure （1 and 2 k.al/min）, in random order, separated by 2h fasting. Data were compared with 15 non-diabetic critically ill patients （48 ± 5 years） and 10 healthy volunteers （28 ±3 years）. RESULTS： Baseline proximal gastric volumes were similar between the three groups. In diabetic patients, proximal gastric relaxation during I k.al/min nutrient infusion was similar to non-diabetic patients and healthy controls. In contrast, relaxation during 2 k.al/ min infusion was initially reduced in diabetic patients （P 〈 0.05） but increased to a level similar to healthy humans, unlik. non-diabetic patients where relaxation was impaired throughout the infusion. Duodenal nutrient stimulation reduced the fundic wave frequency in a dose-dependent fashion in both the critically ill diabetic patients and healthy subjects, but not in critically ill patients without diabetes. Fundic wave frequency in diabetic patients and healthy subjects was greater than in non-diabetic ***： In patients with diabetes mellitus, proximal gastric motility is less disturbed than nondiabetic patients during critical illness, suggesting that these patients may not be at greater risk.of delayed gastric emptying.

Back.round: Uterine Didelphys is a rare congenital condition and it can affect both mother and fetus. A 24 year-old patient presented to the emergency room with pelvic pain and a pelvic ultrasound confirmed the presence of Uterine Didelphys. She subsequently became pregnant and was first seen at 21 week. gestation. She was designated as a high-risk.patient during the second trimester when she experienced irregular contractions. She was monitored week.y with Non-Stress Tests and eventually was delivered by Cesarean Section. Uterine Didelphys can be detected in-utero in affected individuals, and clinical findings vary among individuals. Some may be asymptomatic, whereas others will experience dyspareunia, and still others may present with concurrent renal agenesis. Serial sonograms are performed throughout their pregnancy to evaluate fetal growth and well-being, as well as cervical length. Unlik. many uterine anomalies, Uterine Didelphys does not affect fertility but can affect labor, fetal growth, placentation, fetal viability and fetal outcome. Uterine Didelphys frequently results in recurrent miscarriages and may cause preterm labor and necessitate cesarean section. The presentation, associated symptoms, methods of detection and management options for Uterine Didelphys will be discussed.

AIM: To assess the impact of bolus volume on the characteristics of small intestinal (SI) impedance ***: Concurrent SI manometry-impedance measurements were performed on 12 healthy volunteers to assess the pattern of proximal jejunal fluid bolus movement over a 14 *** subject was given 34 boluses of normal saline (volume from 1 to 30 mL) via the feeding tube placed immediately above the proximal margin of the studied segment.A bolus-induced impedance event occurred if there was > 12% impedance drop from baseline,over ≥ 3 consecutive segments within 10 s of bolus injection.A minor or major imped-ance event was defined as a duration of impedance drop < 60 s or ≥ 60 s,***: The minimum volume required for a detectable SI impedance event was 2 mL.A direct linear relationship between the SI bolus volume and the occurrence of impedance events was noted until SI bolus volume reached 10 mL,a volume which always produced an impedance flow *** was a moderate correlation between the bolus volume and the duration of impedance drop (r = 0.63,P < 0.0001) and the number of propagated channels (r = 0.50,P < 0.0001).High volume boluses were associated with more major impedance events (≥ 10 mL boluses = 63%,3 mL boluses = 17%,and < 3 mL boluses = 0%,P = 0.02).CONCLUSION: Bolus volume had an impact on the type and length of propagation of SI impedance events and a threshold of 2 mL is required to produce an event.
