Fetal asphyxia, a condition resulting from the combined effects of hypoxia and hypercapnia, leads to approximately 900,000 annual deaths worldwide. One cause is umbilical cord compression during labor-induced uterine contractions, disrupting the transport of metabolites to and from the placenta, and resulting in asphyxia. Current fetal well-being assessment relies on monitoring fetal heart rate and uterine contractions as indicators of oxygen delivery to the brain.

The patient with heart failure (HF) is a frequent scenario in primary care consultations. The presence of subclinical congestion is a predictor of rehospitalization and adverse events in these patients. The assessment of congestion is complex due to the low sensitivity of classic symptoms and signs, which leads to underdiagnosis, delayed initiation of treatment and a greater likelihood of complications.

As customized artistic commodities, export paintings mirrored Guangzhou's unique overseas trade culture and social power in a microscopic view, nevertheless, few researchers have delved into the cultural relationship between the use of the painting techniques and the characters of the export paintings. Based on an iconographic approach, this article aims to analyze the historical iconography information of the Qing dynasty export paintings from the perspective of the trade development and cultural exchange between the East and West during the 18th century by the study of the export paintings' characters expressions and costumes colors, providing insights into the exploration of the value of tangible cultural heritage. In the process of our research, shows that: 1) the dominant laboring characters in the export paintings present standing postures, and most of them demonstrate negative emotions; 2) many of the characters of the export paintings show high similarities due to the assembly-line mode of painting during manufacture; 3) the portrayal of the characters in the export paintings reflects a return of a sense of humanity.

Article Synopsis
- * Using patient data, the CFD model simulated blood flow dynamics in the connection between the pulmonary veins and the left atrium while analyzing various anastomosis sizes for their impact on flow velocity, pressure, and energy loss.
- * Results showed that larger anastomotic sizes led to lower energy loss and pressure, but sizes above 18 mm provided no additional efficiency gains, helping surgeons better plan preoperative procedures for TAPVC.
