Prevalence of undernutrition in surgical patients and the effect on length of hospital stay.
Low nutritional status is common among surgical patients. A low nutrition profile is related to muscle weakness and immune suppression, which may be associated with negative outcomes. In this study, we evaluated the prevalence of low nutrition and assessed the relationship between nutritional status and length of hospital stay in surgical patients. ⋯ Our results suggest that a low nutrition profile before surgery is associated with a prolonged hospital stay.

Randomized Controlled TrialSafety and efficacy of an automated anesthesia delivery system for total intravenous anesthesia with propofol, remifentanil, and rocuronium: a non-inferiority randomized controlled trial versus manually controlled anesthesia.
We have developed an automated anesthesia control system that uses biological information to provide closed-loop control of drug administration for total intravenous anesthesia with propofol, remifentanil, and rocuronium. In this study, we investigated whether the control of sedatives, analgesics, and muscle relaxants delivered by this system is non-inferior to that delivered by anesthesiologists. ⋯ The clinical use of our automated anesthesia control system should allow for the maintenance of adequate anesthesia by adjusting the doses of intravenous anesthetics in the same way as anesthesiologists do.

Randomized Controlled TrialInvestigation of the optimal method of oxygen administration with simultaneous use of a surgical mask: a randomized control study.
From the perspective of infection prevention during the Coronavirus disease 2019 (COVID-19) pandemic, a recommendation was made to use surgical masks after extubation in patients in the operating room. For compliance with this recommendation, anesthesiologists need to administer oxygen to the patient with an oxygen mask over the surgical mask. However, no studies have investigated whether this method allows good maintenance of oxygenation in patients. This study aimed to investigate which method of oxygen administration lends itself best to use with a surgical mask in terms of oxygenation. ⋯ Wearing a surgical mask over the nasal cannula during oxygen administration is beneficial for oxygenation and might help prevent aerosol dispersal.

Quantitative and qualitative analyses of urinary L-FABP for predicting acute kidney injury after emergency laparotomy.
The aim of this study was to explore the clinical utility of urinary L-FABP for earlier prediction of acute kidney injury (AKI) after emergency laparotomy, and to assess the clinical utility of a point-of-care (POC) kit for urinary L-FABP. ⋯ Quantitative L-FABP analyses is suitable for predicting postoperative AKI earlier in the perioperative period of emergency laparotomy. Conversely, the higher specificity of qualitative L-FABP analysis suggests that it may be useful for excluding the risk of AKI but its overall clinical validity should be further investigated.
