This study investigated whether pain and pain-related unpleasantness ratings were altered by blood testosterone levels. We also investigated whether activation of brain regions that represent pain intensity [primary somatosensory cortex (S1)] and pain-related unpleasantness [perigenual ACC (pACC) and orbitofrontal cortex (OFC)] were affected by blood testosterone levels. ⋯ Compared to the high testosterone group, the low testosterone group had significant activation in the pACC and OFC, regions that represent pain-related unpleasantness, but not in S1 that represents pain intensity, leading to higher pain ratings. These findings emphasize the importance of considering the effects of testosterone levels when treating patients.

Randomized Controlled Trial Comparative StudyUltrasound-guidance outperforms the palpation technique for peripheral venous catheterisation in anaesthetised toddlers: a randomised study.
Traditional palpation technique for peripheral venous catheter (PVC) placement can be challenging. We aimed to compare the Dynamic Needle Tip Positioning (DNTP) ultrasound technique with the palpation technique for PVC placement in anaesthetised toddlers undergoing elective, low-risk procedures. ⋯ Ultrasound-guidance outperforms the traditional palpation technique for peripheral venous catheterisation in anaesthetised toddlers undergoing elective, low-risk procedures.

Does obesity complicate regional anesthesia and result in longer decision to delivery time for emergency cesarean section?
Maternal obesity can cause problems with anesthesia and surgery which may be reflected in emergency cesarean sections (CS) as an increased decision-to-delivery interval (DDI). ⋯ Higher BMI was associated with longer DDI and more regional anesthesia failures. Epidural top-up was faster than CSE for establishing CS anesthesia.

Observational StudyHypophosphatemia after nontraumatic intracranial hemorrhage.
The aim of this study was to assess the incidence and contributing factors of hypophosphatemia and the association with poor long-term outcome after nontraumatic intracranial hemorrhage. ⋯ Hypophosphatemia was common in this patient population. The outcome was similar between hypophosphatemic and normophosphatemic patients. Chronic hypertension, acute hydrocephalus, diffuse brain edema and higher SOFA scores were more common in patients with hypophosphatemia.
