The Journal of toxicological sciences 50(2) 69-73 2025年 筆頭著者Acute carbon monoxide poisoning (ACOP) is a cause of accidental or deliberate deaths worldwide. Subsequent complications, particularly delayed neurological sequelae (DNS), are preventable and treatable based on their pathophysiology. Hyperbaric oxygenation therapy (HBO) is a potential procedure for preventing and treating DNS; however, the effects of HBO on DNS are unclear and debated. In the present study, we investigated which factors are associated with the development of DNS and the effects of HBO in patients with ACOP. We performed retrospective subanalyses of the COP-J registry, focusing on adults who underwent HBO, regardless of whether they developed DNS. The multivariable analysis showed that the Glasgow coma scale (GCS) on admission was significantly associated with DNS (odds ratio 0.736; 95% confidence interval 0.608-0.892; P = 0.002). The receiver operating characteristic curve analysis of GCS for DNS revealed a cutoff value of 12.5 according to Youden's index (sensitivity 80.8%, specificity 76.9%). This retrospective analysis of a nationwide Japanese registry of ACOP showed that low GCS scores on admission could be a predictive factor for DNS, with a possible cutoff value of ≤12, in patients who undergo HBO.

Cureus 15(2) e35233 2023年4月BACKGROUND: Positive end-expiratory pressure (PEEP), especially continuous high PEEP, is thought to be a risk factor for worsening renal function (WRF) due to impaired venous return and the development of renal interstitial edema. In this study, we investigated whether PEEP is a risk factor for WRF in patients with acute respiratory distress syndrome (ARDS), a representative pathology that requires continuous high PEEP for respiratory management. METHODS: We performed retrospective sub-analyses of the Japanese Association for Acute Medicine, a nationwide prospective observational registry of ARDS (FORECAST ARDS registry) prospective multicenter cohort study. WRF was defined on the basis of a worsening renal Sequential Organ Failure Assessment (SOFA) score. We performed univariate and multivariable analyses to identify possible risk factors for WRF, and propensity score analyses to compare the frequency of WRF according to cutoff values for the difference in PEEP between day 1 and day 4. RESULTS: We analyzed 151 cases. Multivariable analysis showed that the difference in PEEP (odds ratio (OR) 1.123 (95% confidence interval (CI) 1.017-1.240), P = 0.022) and male sex (OR 3.287 (95% CI 1.029-10.502), P = 0.045) were risk factors for WRF. Propensity score analysis showed trends towards an increased risk for WRF in each cutoff value for the difference in PEEP: -5 cmH2O (OR 0.389 (95% CI 0.084-1.799), P = 0.229), 0 cmH2O (OR 2.222 (95% CI 0.755-6.540), P = 0.150), and 5 cmH2O (OR 3.277 (95% CI 0.940-11.425), P = 0.065). CONCLUSIONS: This study revealed that the difference in PEEP between days 1 and 4 was positively associated with WRF. However, a significant cutoff value for the difference in PEEP was not determined.

PloS one 18(5) e0285525 2023年BACKGROUND: The purpose of this study was to examine whether the temperature difference between the jugular bulb and pulmonary artery (ΔTjb-pa) is associated with the neurological outcome of patients with severe traumatic brain injury (TBI). METHODS: We conducted a post hoc analysis of a multicenter randomized controlled trial of mild therapeutic hypothermia (TH, 32.0-34.0°C) or fever control (FC, 35.5-37.0°C) for the patients with severe TBI. ΔTjb-pa averaged every 12 h and the variation in ΔTjb-pa were compared between patients with favorable (n = 39) and unfavorable (n = 37) neurological outcomes. These values were also compared in the TH and FC subgroups. RESULTS: The average ΔTjb-pa values in patients with favorable and unfavorable outcomes were 0.24 ± 0.23 and 0.06 ± 0.36°C, respectively (P < 0.001). ΔTjb-pa trended significantly higher in the favorable outcome patients than in the unfavorable outcome patients throughout the 120 h after onset of severe TBI (P < 0.001). The variation in ΔTjb-pa from 0 to 72 h was significantly lower in the favorable outcome patients than in the unfavorable outcome patients (0.8 ± 0.8 vs 1.8 ± 2.5°C, respectively, P = 0.013). From 72 to 120 h, there was no significant difference in the variation in ΔTjb-pa. Significant differences between patients with favorable and unfavorable outcomes in ΔTjb-pa and the variation in ΔTjb-pa were similar in the TH subgroup, but not evident in the FC subgroup. CONCLUSIONS: A reduction in ΔTjb-pa and greater variation in ΔTjb-pa were associated with an unfavorable outcome in patients with severe TBI, especially those treated with TH. When treating severe TBI patients, it is important to understand that there will be differences in temperature reflecting the brain environment and the systemic temperature, depending on the severity and outcome of TBI during TH.

Trauma case reports 42 100710-100710 2022年12月Tracheobronchial injury (TBI) associated with penetrating injuries has various clinical symptoms and often requires urgent surgical repair. A tracheal tube and/or placement of a drainage tube combined with multidetector computed tomography (CT) could be used to manage TBI without surgical repair in eligible patients. In this case report, we describe an 86-year-old woman with subcutaneous emphysema and suspected TBI caused by three knife wounds in her neck. After tracheal intubation at a local hospital, she was transferred to our hospital. On admission, she was diagnosed with subcutaneous and mediastinal emphysema due to TBI, as well as bilateral pneumothorax. We adjusted the position of the tracheal tube to a distal location from the TBI, and placed bilateral thoracic drainage tubes by referring to the CT images taken on admission and during the follow-up. The follow-up CT images revealed healing of the TBI. She did not show any worsening of her symptoms and she was successfully extubated on day 10 of her hospital stay. On day 18, she was considered self-reliant and was transferred to her previous hospital. Based on our experience in this case, we believe that ventilation with appropriate sedation, placement of a tracheal tube, and drainage are important conservative therapies for TBI caused by penetrating injuries. CT is also useful for evaluating the status of TBI.

Scientific reports 12(1) 16373-16373 2022年9月30日Heatstroke is a life-threatening event that affects people worldwide. Currently, there are no established tools to predict the outcomes of heatstroke. Although the Sequential Organ Failure Assessment (SOFA) score is a promising tool for judging the severity of critically ill patients. Therefore, in this study, we investigated whether the SOFA score could predict the outcome of patients hospitalized with severe heatstroke, including the classical and exertional types, by using data from a Japanese nationwide multicenter observational registry. We performed retrospective subanalyses of the Japanese Association for Acute Medicine heatstroke registry, 2019. Adults with a SOFA score ≥ 1 hospitalized for heatstroke were analyzed. We analyzed data for 225 patients. Univariate and multivariable analyses showed a significant difference in the SOFA score between non-survivors and survivors in classical and exertional heatstroke cases. The area under the receiver operating characteristic curve were 0.863 (classical) and 0.979 (exertional). The sensitivity and specificity of SOFA scores were 50.0% and 97.5% (classical), 66.7% and 97.5% (exertional), respectively, at a cutoff of 12.5, and 35.0% and 98.8% (classical), 33.3% and 100.0% (exertional), respectively, at a cutoff of 13.5. This study revealed that the SOFA score may predict mortality in patients with heatstroke and might be useful for assessing prognosis.

Neurotrauma reports 3(1) 250-260 2022年Therapeutic hypothermia for severe traumatic brain injury (TBI) has been repeatedly studied, but no past studies have assessed the detailed head computed tomography (CT) findings. We sought to investigate individual CT findings of severe TBI patients treated with targeted temperature management utilizing the head CT database obtained from the Brain Hypothermia study. Enrolled patients underwent either mild therapeutic hypothermia (32.0°C-34.0°C) or fever control (35.5°C-37.0°C). We assessed individual head CT images on arrival and after rewarming and investigated the correlations with outcomes. The initial CT data were available for 125 patients (hypothermia group = 80, fever control group = 45). Baseline characteristics and CT findings, such as hematoma thickness and midline shift, were similar in all aspects between the two groups. The favorable outcomes in the hypothermia and fever control groups were 38 (47.5%) and 24 (53.3%; p = 0.53) for all 125 patients, respectively; 21 (46.7%) vs. 10 (38.5%; p = 0.50) for 71 patients with acute subdural hematoma (SDH), respectively; and 12 (75.0%) vs. 4 (36.4%; p = 0.045) in 27 young adults (≤50 years) with acute SDH, respectively. There was a trend toward favorable outcomes for earlier time to reach 35.5°C (190 vs. 377 min, p = 0.052) and surgery (155 vs. 180 min, p = 0.096) in young patients with acute SDH. The second CT image revealed progression of the brain injury. This study demonstrated the potential benefits of early hypothermia in young patients with acute SDH, despite no difference in CT findings between the two groups. However, the small number of cases involved hindered the drawing of definitive conclusions. Future studies are warranted to validate the results.

Respir Med Case Rep 34 101513-101513 2021年10月 査読有り筆頭著者責任著者Antineutrophil cytoplasmic antibody-associated vasculitis (AAV) is sometimes complicated by diffuse alveolar hemorrhage (DAH), which may cause respiratory failure. Venovenous extracorporeal membrane oxygenation (VV-ECMO) without an anticoagulant because of hemorrhagic status, showed the effectiveness for severe respiratory failure by DAH with AAV. A 44-year-old woman developed DAH with bowel bleeding following the onset of AAV, with positive anti-proteinase-3 (PR3) antibodies. Although ventilator management could not support her respiratory status, VV-ECMO was performed. The patient was given immunosuppressive therapy comprising a steroid pulse, plasma exchange, and cyclophosphamide. After about 10 days of VV-ECMO and immunosuppressive therapy, VV-ECMO was withdrawn, and on day 12, ventilator support was stopped. Although a thrombus developed within the inferior vena cava (IVC), which required IVC filtration, the patient was discharged on day 51. VV-ECMO support was effective for treating DAH in this patient with new-onset AAV, which takes some time to achieve remission with immunosuppressive therapy.
