Effect of blood sample storage period on d-ROMs and BAP test data.

The Diacron-reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) tests can easily and rapidly measure the state of oxidative stress in the blood; they have been used to determine the relationship between oxidative stress and various diseases. However, the extent to which the blood storage period affects the analyzed data remains unclear. In clinical practice, the storage conditions for samples after blood collection vary.

Analysis of Maternal and Fetal Oxidative Stress During Delivery with Epidural Analgesia.

Childbirth is a stressful event for mothers, and labor epidural analgesia (LEA) may reduce mental stress. Mental stressors include labor pain, fear, and anxiety, which induce oxidative stress. In this study, we focused on oxidative stress during delivery and conducted a cross-sectional analysis of maternal and fetal oxidative stress.

Outcomes of severe peripartum cardiomyopathy and mechanical circulatory support: a case series.

Background: We present three cases of severe peripartum cardiomyopathy (PPCM) that required mechanical circulatory supports.

Case Presentation: Case 1: A 33-year-old woman developed acute heart failure (AHF) after normal spontaneous delivery. Intra-aortic balloon pump (IABP) was inserted on postpartum day (PD) 10 with a peripartum cardiomyopathy (PPCM), which was withdrawn on PD 30 after medical treatment including anti-prolactin drugs.

Use of Continuous Electrical Impedance Measurement for Accurate Nerve Block in Rabbits.

Objective: To perform an effective and safe nerve block, the needle must be placed near the target nerve while avoiding nerve damage. Our objective was to conduct an animal study to determine whether changes in electrical impedance (EI) could be used to guide the needle and achieve a safe and accurate nerve block.

Methods: We measured the EI of rabbit tissues during ultrasound-guided sciatic nerve block using a bipolar needle via the in-plane needle approach.
