Post-induction hypotension and intraoperative hypotension as potential separate risk factors for the adverse outcome: a cohort study.
Intraoperative hypotension (IOH) is associated with organ hypoperfusion. There are different underlying causes of IOH depending on the phase of surgery. Post-induction hypotension (PIH) and early-intraoperative hypotension tend to be frequently differentiated. We aimed to explore further different phases of IOH and verify whether they are differently associated with postoperative complications. ⋯ The presence of IOH defined as MAP ≤ 65 mmHg is relevant to post-operative organ complications, the presence of PIH does not appear to be of such significance. Because cumulative duration of PIH and IOH differs significantly, especially in long-lasting procedures, direct comparison of the influence of PIH and IOH on outcome separately may be biased and should be taken into account in data interpretation. Further research is needed to deeply investigate this phenomenon.

Observational StudyEffects of preoperative nutritional status on disability-free survival after cardiac and thoracic aortic surgery: a prospective observational study.
Preoperative malnutrition is associated with postoperative complications, prolonged intensive care unit stay, and mortality, leading to functional disability after non-cardiac surgery. However, its effects on cardiac and thoracic aortic surgery outcomes remain unknown. We examined the effects of preoperative malnutrition on disability-free survival after surgery and assessed the perioperative 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS2.0) score based on the preoperative nutritional status. ⋯ Patients with a poor preoperative nutritional status had less likely to show disability-free survival 1 year after cardiac and thoracic aortic surgery.

Observational StudyPredictors of early postoperative cognitive dysfunction in middle-aged patients undergoing cardiac surgery: retrospective observational study.
This study aimed to identify the incidence and risk factors of early post-operative cognitive dysfunction (POCD) in middle-aged patients undergoing cardiac surgery. ⋯ More than one-third of middle-aged patients undergoing cardiac surgery developed POCD. Our findings suggested preoperative MCI and infarcts detected by MRI were risk factors for POCD in these middle-aged patients.

Authorship by gender in anesthesiology journals: a retrospective cross-sectional study for Japan.
Although it is important to recognize gender disparities in publishing to achieve gender diversity, women's authorship in Japan remains unclear. Therefore, this study aimed to investigate the percentage and analyze the trends of articles authored and published in anesthesiology journals by Japanese female authors. ⋯ The percentage of female first authors has increased, commensurate with the percentage of female anesthesiologists. However, the percentage of female last authors has not increased and remains low in Japan.

Efficacy of prophylactic high-flow nasal cannula therapy for postoperative pulmonary complications after pediatric cardiac surgery: a prospective single-arm study.
This study investigated the incidence of postoperative pulmonary complications (PPC) when high-flow nasal cannula therapy (HFNC) is used prophylactically after pediatric cardiac surgery, and evaluated its efficacy. ⋯ We found the incidence of PPC with prophylactic HFNC after planned extubation after pediatric cardiac surgery. However, the incidence was > 10%; therefore, we could not demonstrate its efficacy in this single-arm study. Further studies are needed to investigate whether the HFNC could be adapted as first-line oxygen therapy after pediatric cardiac surgery.
