This study aimed to propose a revised ypN (r-ypN) classification based on lymph node ratio (LNR) and to examine its prognostic value in postneoadjuvant esophageal cancer. ⋯ LNR showed better performance than ypN in predicting OS of esophageal cancer patients after neoadjuvant chemoradiation and may be an improvement on the current staging system.

ReviewCurrent hemoglobin thresholds in pediatric anesthesia - guidelines and studies.
The use of restrictive transfusion triggers to avoid unnecessary transfusions is one important pillar of Patient Blood Management (PBM). For the safe application of this principle in pediatric patients, anesthesiologists need evidence-based guidelines for hemoglobin (Hb) transfusions thresholds in this specially vulnerable age-group. ⋯ Two high-quality studies confirmed that the use of restrictive transfusion triggers in preterm infants in the intensive care unit (ICU) is reasonable and feasible. Unfortunately, no recent prospective study could be found investigating intraoperative transfusion triggers. Some observational studies showed wide variability in Hb levels before transfusion, a tendency toward restrictive transfusion practices in preterm infants, and liberal transfusion practices in older infants. Although there are comprehensive and useful guidelines for clinical practice in pediatric transfusion, most of them do not cover the intraoperative period in particular because of a lack of high-quality studies. This lack of prospective randomized trials focusing on intraoperative transfusion management remains a major problem for the application of pediatric PBM.

Controlled Clinical Trial
Aftereffects of alpha transcranial alternating current stimulation over the primary sensorimotor cortex on cortical processing of pain.
Transcranial alternating current stimulation (tACS) is believed to modulate brain oscillations in a frequency-specific manner. Given the correlation between sensorimotor α-oscillations and pain perception, tACS that targets sensorimotor α-oscillations has the potential to reduce pain. Therefore, this study sought to determine the aftereffects of α-tACS over unilateral primary sensorimotor cortex (SM1) on the perceptual and neural responses to noxious painful stimulation of the contralateral hand. ⋯ Moreover, α-tACS decreased the functional connectivity between the targeted SM1 and a network of regions that are crucially involved in pain processing, including the middle cingulate cortex, contralateral somatosensory cortex, and dorsolateral prefrontal cortex. These results demonstrated that after α-tACS applied over the unilateral SM1 does attenuate subsequent neural processing of pain within bilateral sensorimotor regions as well as sensorimotor functional connectivity. The findings provide evidence that sensorimotor α-oscillations directly affect pain processing and support the application of sensorimotor α-tACS for inducing pain analgesia.

Randomized Controlled TrialUltrasonographic assessment of metoclopramide effect on gastric volume in parturients females undergoing Caesarean section: a randomized double blind study.
The prokinetic effect of metoclopramide promotes gastric emptying and decreases stomach capacity. The aim of the present study was to assess the efficacy of metoclopramide in reducing gastric contents and volume using gastric point-of-care ultrasonography (PoCUS) in parturients females prepared for elective Cesarean section under general anesthesia. ⋯ Metoclopramide decreases gastric volume, reduces postoperative nausea and vomiting, and may lower the risk of aspiration when used as premedication before obstetric surgery. Preoperative gastric PoCUS has utility in objectively assessing stomach volume and contents.
