RESUMEN
PURPOSE: Although the most recent systematic review and meta-analyses on acute respiratory distress syndrome (ARDS) have shown that the use of steroids decreases mortality in adult patients, its benefits and risks may differ depending on the type and dosage of the steroid. Therefore, we conducted a network meta-analysis (NMA) to compare the differences in the efficacy among different doses and types of steroids. METHODS: We searched MEDLINE, CENTRAL, ICHUSHI, ClinicalTrials.gov, and WHO ICTRP databases from the earliest records to March 2021 for randomized control trials, which compared steroids with placebo or conventional therapy for ARDS. Using the random-effects model, we compared various categories of steroids (high-dose methylprednisolone, low-dose methylprednisolone, hydrocortisone, dexamethasone, and no steroid) concerning hospital mortality, incidence of infection, and ventilator-free days (VFD). RESULTS: We analyzed nine studies involving adult patients (n = 1212). Although there were no significant differences between the groups in terms of the mortality and incidence of infection, the number of VFD were greater when using low-dose methylprednisolone than when not using any steroids (Mean difference: 6.06; 95% confidence intervals: [2.5, 10.5]). Moreover, the rank probability showed that low-dose methylprednisolone might be the optimal treatment, whereas using no steroid or high-dose methylprednisolone may be inferior to other treatments in terms of mortality, infection, and VFD. CONCLUSION: This NMA suggested that the effect of steroids on the outcome in patients with ARDS might depend on the type of the steroid drug administered. Moreover, further studies are needed to identify the optimal type and dosage.

BACKGROUND: Serum neutrophil gelatinase-associated lipocalin (NGAL) is a well-known biomarker of acute kidney injury. Serum NGAL was recently proposed as a potential predictor of mortality in post cardiac arrest syndrome (PCAS) patients following out-of-hospital cardiac arrest (OHCA). However, the potential predictive value of NGAL for neurological outcomes is unknown. Therefore, we assessed the potential predictive value of NGAL for neurological outcomes after OHCA. We also compared its predictive value with that of neuron-specific enolase (NSE) as an established biomarker. METHODS: Blood samples were prospectively collected from 43 PCAS patients following OHCA. Serum NGAL was measured on days 1 and 2, and NSE was measured on day 2. These biomarkers were compared between patients with favourable (cerebral performance category [CPC] 1-2) and unfavourable (CPC 3-5) outcomes. Receiver operating characteristic (ROC) curve analysis was performed. RESULTS: Serum NGAL and NSE on day 2 (both P < 0.001), but not NGAL on day 1 (P = 0.609), were significantly different between the favourable and unfavourable groups. In ROC curve analysis, the sensitivity and specificity were 83% and 85%, respectively, for NGAL (day 2) at a cutoff value of 204 ng/mL and were 84% and 100% for NSE (day 2) at a cutoff value of 28.8 ng/mL. The area under the ROC curve of NGAL (day 2) was equivalent to that of NSE (day 2) (0.830 vs. 0.918). Additionally, the area under the ROC curve in subgroup of estimated glomerular filtration rate (eGFR) > 20 mL/min/1.73 m2 (n = 38, 0.978 vs. 0.923) showed the potential of NGAL predictability. CONCLUSIONS: Serum NGAL might predict the neurological outcomes of PCAS patients, and its predictive value was equivalent to that of NSE.

INTRODUCTION: The Berlin definition divides acute respiratory distress syndrome (ARDS) into three severity categories. The relationship between these categories and pulmonary microvascular permeability as well as extravascular lung water content, which is the hallmark of lung pathophysiology, remains to be elucidated. The aim of this study was to evaluate the relationship between extravascular lung water, pulmonary vascular permeability, and the severity categories as defined by the Berlin definition, and to confirm the associated predictive validity for severity. METHODS: The extravascular lung water index (EVLWi) and pulmonary vascular permeability index (PVPI) were measured using a transpulmonary thermodilution method for three consecutive days in 195 patients with an EVLWi of ≥10 mL/kg and who fulfilled the Berlin definition of ARDS. Collectively, these patients were seen at 23 ICUs. Using the Berlin definition, patients were classified into three categories: mild, moderate, and severe. RESULTS: Compared to patients with mild ARDS, patients with moderate and severe ARDS had higher acute physiology and chronic health evaluation II and sequential organ failure assessment scores on the day of enrollment. Patients with severe ARDS had higher EVLWi (mild, 16.1; moderate, 17.2; severe, 19.1; P <0.05) and PVPI (2.7; 3.0; 3.2; P <0.05). When categories were defined by the minimum PaO2/FIO2 ratio observed during the study period, the 28-day mortality rate increased with severity categories: moderate, odds ratio: 3.125 relative to mild; and severe, odds ratio: 4.167 relative to mild. On independent evaluation of 495 measurements from 195 patients over three days, negative and moderate correlations were observed between EVLWi and the PaO2/FIO2 ratio (r = -0.355, P<0.001) as well as between PVPI and the PaO2/FIO2 ratio (r = -0.345, P <0.001). ARDS severity was associated with an increase in EVLWi with the categories (mild, 14.7; moderate, 16.2; severe, 20.0; P <0.001) in all data sets. The value of PVPI followed the same pattern (2.6; 2.7; 3.5; P <0.001). CONCLUSIONS: Severity categories of ARDS described by the Berlin definition have good predictive validity and may be associated with increased extravascular lung water and pulmonary vascular permeability.

A 60-year-old man was admitted to our hospital because of right flank pain. An irregular cystic mass region with calcification was detected in his right abdomen on computed tomography( CT). On the fifth day after admission, the patient's abdominal pain suddenly worsened. Based on a diagnosis of panperitonitis, we performed an urgent laparotomy on the same day. A bulky tumor involving the right colon, duodenum, and retroperitoneum was found in his abdominal cavity. We performed right hemicolectomy and partial resection of the duodenum but could not completely excise the tumor. The manipulation caused a serious duodenal injury; and therefore, pyloric antrum transection, gastrojejunostomy, and cholecystostomy were performed to reduce the inflow of gastric content and bile. Histological examination of the surgical specimens revealed a moderately differentiated adenocarcinoma that originated from the ascending colon. Many cancer cells were detected in the excised margin; thus, the surgical maneuver of choice was absolute noncurative resection. If peritonitis had not been observed, preoperative chemotherapy would have been more appropriate.

We present the case of a patient who was admitted because of acute pan-peritonitis but was found to have locally advanced rectal cancer that was successfully excised after preoperative chemotherapy. A 68-year-old man was transferred to our hospital via an ambulance because of severe lower abdominal pain. His abdominal computed tomography scan showed a huge tumor in the pelvis. An emergency sigmoid colostomy was performed because of panperitonitis. However, his postoperative examinations indicated locally advanced rectal cancer accompanied with extensive urinary bladder invasion but without distant metastasis, and chemotherapy was started. Eventually, the tumor reduced to 47% of its maximum size after 4 courses of FOLFOX6 and 2 courses of FOLFOX6+panitumumab, and radical excision( low anterior rectal resection, partial urinary bladder resection, D3 lymph node dissection, and total mesorectal excision) was performed on the 154th day since the first operation. No cancer cells were detected on microscopic analysis of the margins of the excised specimen. Thus, preoperative chemotherapy is useful for treating locally advanced rectal cancer.

A 64-year-old man with sudden upper abdominal pain and emesis was admitted to our hospital. Forty years ago, he had undergone distal gastrectomy and reconstruction by Billroth II anastomosis for gastric cancer. Abdominal computed tomography revealed a dilated afferent loop and anastomotic tumor. Gastrofiberscopy showed crookedness and edematization of the afferent loop anastomosis. A biopsy revealed a poorly differentiated adenocarcinoma. He was operated on under the diagnosis of remnant gastric cancer. Left upper exenteration was performed because the transverse colon, lateral segment of the liver, pancreas, and left renal hilus were involved. Liver metastasis and abdominal dissemination were not observed. Histopathological findings revealed severe invasion of poorly differentiated adenocarcinoma to other organs, and intraoperative peritoneal lavage cytology was positive. He was discharged from our hospital; however, adjuvant chemotherapy was impossible because of his poor condition. Four months after the operation, he died from peritoneal carcinomatosis. Remnant gastric cancer with afferent loop syndrome has a poor prognosis. Therefore, it is necessary to select surgical resection or palliative care after immediate chemotherapy, considering each patient's condition and cancer stage.

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.
RESUMEN
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.

We aim to develop a deep-learning-based method for automatic proximal femur segmentation in quantitative computed tomography (QCT) images. We proposed a spatial transformation V-Net (ST-V-Net), which contains a V-Net and a spatial transform network (STN) to extract the proximal femur from QCT images. The STN incorporates a shape prior into the segmentation network as a constraint and guidance for model training, which improves model performance and accelerates model convergence. Meanwhile, a multi-stage training strategy is adopted to fine-tune the weights of the ST-V-Net. We performed experiments using a QCT dataset which included 397 QCT subjects. During the experiments for the entire cohort and then for male and female subjects separately, 90% of the subjects were used in ten-fold stratified cross-validation for training and the rest of the subjects were used to evaluate the performance of models. In the entire cohort, the proposed model achieved a Dice similarity coefficient (DSC) of 0.9888, a sensitivity of 0.9966 and a specificity of 0.9988. Compared with V-Net, the Hausdorff distance was reduced from 9.144 to 5.917 mm, and the average surface distance was reduced from 0.012 to 0.009 mm using the proposed ST-V-Net. Quantitative evaluation demonstrated excellent performance of the proposed ST-V-Net for automatic proximal femur segmentation in QCT images. In addition, the proposed ST-V-Net sheds light on incorporating shape prior to segmentation to further improve the model performance.
RESUMEN
INTRODUCTION: Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is characterized by features other than increased pulmonary vascular permeability. Pulmonary vascular permeability combined with increased extravascular lung water content has been considered a quantitative diagnostic criterion of ALI/ARDS. This prospective, multi-institutional, observational study aimed to clarify the clinical pathophysiological features of ALI/ARDS and establish its quantitative diagnostic criteria. METHODS: The extravascular lung water index (EVLWI) and the pulmonary vascular permeability index (PVPI) were measured using the transpulmonary thermodilution method in 266 patients with PaO2/FiO2 ratio ≤ 300 mmHg and bilateral infiltration on chest radiography, in 23 ICUs of academic tertiary referral hospitals. Pulmonary edema was defined as EVLWI ≥ 10 ml/kg. Three experts retrospectively determined the pathophysiological features of respiratory insufficiency by considering the patients' history, clinical presentation, chest computed tomography and radiography, echocardiography, EVLWI and brain natriuretic peptide level, and the time course of all preceding findings under systemic and respiratory therapy. RESULTS: Patients were divided into the following three categories on the basis of the pathophysiological diagnostic differentiation of respiratory insufficiency: ALI/ARDS, cardiogenic edema, and pleural effusion with atelectasis, which were noted in 207 patients, 26 patients, and 33 patients, respectively. EVLWI was greater in ALI/ARDS and cardiogenic edema patients than in patients with pleural effusion with atelectasis (18.5 ± 6.8, 14.4 ± 4.0, and 8.3 ± 2.1, respectively; P < 0.01). PVPI was higher in ALI/ARDS patients than in cardiogenic edema or pleural effusion with atelectasis patients (3.2 ± 1.4, 2.0 ± 0.8, and 1.6 ± 0.5; P < 0.01). In ALI/ARDS patients, EVLWI increased with increasing pulmonary vascular permeability (r = 0.729, P < 0.01) and was weakly correlated with intrathoracic blood volume (r = 0.236, P < 0.01). EVLWI was weakly correlated with the PaO2/FiO2 ratio in the ALI/ARDS and cardiogenic edema patients. A PVPI value of 2.6 to 2.85 provided a definitive diagnosis of ALI/ARDS (specificity, 0.90 to 0.95), and a value < 1.7 ruled out an ALI/ARDS diagnosis (specificity, 0.95). CONCLUSION: PVPI may be a useful quantitative diagnostic tool for ARDS in patients with hypoxemic respiratory failure and radiographic infiltrates. TRIAL REGISTRATION: UMIN-CTR ID UMIN000003627.

We report 2 cases of retroperitoneal liposarcoma. Case 1: A 53-year-old woman with severe abdominal distension and dyspnea was admitted to our hospital. Abdominal computed tomography(CT) and magnetic resonance imaging(MRI) revealed a large mass that occupied almost the entire abdominal cavity. She underwent surgery under the diagnosis of retroperitoneal liposarcoma. The tumor originated from the left lower pelvis. The tumor weighed 18 kg, and the histopathological diagnosis was well-differentiated liposarcoma. Seven years after the operation, local recurrence was found without any complaints. The operation was performed again. The tumor weighed 750 g, and it originated from the same area as observed in the first operation. The histopathological diagnosis was well-differentiated liposarcoma. Case 2: An 82-year-old woman complained of abdominal distension. A new dumbbell-like solid tumor was identified as retroperitoneal liposarcoma by CT and MRI findings, and it was growing rapidly. The tumor was removed with the cecum and right kidney in a curative operation. The tumor weighed 2.6 kg, and the histopathological diagnosis was dedifferentiated liposarcoma. The best treatment for retroperitoneal liposarcoma is curative resection. However, dedifferentiation occasionally occurs over time and in recurrent cases. It is important to follow-up strictly for retroperitoneal liposarcoma.

BACKGROUND: Target temperature management (TTM) is an effective component of treating out-of-hospital cardiac arrest (OHCA) after return of spontaneous circulation in conventional cardiopulmonary resuscitation. However, therapeutic hypothermia (32-34 °C TTM) is not recommended based on the results of recent studies. Extracorporeal cardiopulmonary resuscitation (ECPR) with veno-arterial extracorporeal membrane oxygenation is another promising therapy for OHCA, but few studies have examined the effectiveness of ECPR with TTM. Therefore, we hypothesized that ECPR with TTM could have the effectiveness to improve the neurological outcomes for adults following witnessed OHCA, in comparison to ECPR without TTM. METHODS: We performed retrospective subanalyses of the Japanese Association for Acute Medicine OHCA registry. We focused on adults who underwent ECPR for witnessed OHCA. We performed univariate (the Mann-Whitney U test and Fisher's exact test), multivariable (logistic regression analyses), and propensity score analyses (the inverse probability of the treatment-weighting method) with to compare the neurological outcomes between patients with or without TTM, among all eligible patients, patients with a cardiogenic cause, and patients divided into subgroups according to the interval from collapse to pump start (ICPS) (> 30, > 45, or > 60 min). RESULTS: We analyzed data for 977 patients. Among 471 patients treated with TTM, the target temperature was therapeutic hypothermia in 70%, and the median interval from collapse to target temperature was 249 min. Propensity score analysis showed a positive association between TTM and favorable neurological outcomes in all patients (odds ratio 1.546 [95% confidence interval 1.046-2.286], P = 0.029), and in patients with ICPS of > 30 or > 45 min, but not in those with ICPS of > 60 min. The propensity score analysis also showed a positive association between TTM and favorable neurological outcomes in patients with a cardiogenic cause (odds ratio 1.655 [95% confidence interval 1.096-2.500], P = 0.017), including in all ICPS subgroups (> 30, > 45, and > 60 min). CONCLUSION: Within patients who underwent ECPR following OHCA, ECPR with TTM could show the potential of improvement in the neurological outcomes, compared to ECPR without TTM.
RESUMEN
Bromvalerylurea is included in over-the-counter analgesics and is known to cause chronic bromism. Patients can also present acute intoxication because of suicide attempts. The treatment consists of drug cessation and intravenous drip with furosemide. Few reports have described the efficacy of blood purification therapy in a critical case. We report a 21-year-old Japanese woman who was admitted to our hospital in an unconscious state after she had taken 388 tablets of NARON ACE. She was intubated and high flow continuous hemodiafiltration was initiated because her blood pressure remained low, despite continuous intravenous drip infusion. To remove unknown drugs, direct hemoperfusion was performed twice. NARON ACE contains bromvalerylurea, ibuprofen, ethenzamide, and anhydrous caffeine; only the amount of bromvalerylurea was thought to exceed a lethal dose. The plasma concentrations of bromvalerylurea on the first, second, third, and fourth days were 118.9, 45.1, 30.2, and 12.6 µg/mL, respectively. Her level of consciousness improved on the third day and she was extubated. She became stable and was transferred to the psychiatric department to continue medication on day 14. Her clinical course improved, and she was discharged on day 89. In a potentially fatal case, direct hemoperfusion combined with intravenous drip should be considered.

We herein report a 61-year-old man who sustained injury after a 2-m fall and developed mediastinitis. He presented to another hospital two days after the fall and was transferred to our hospital four days after the fall with a fever and dysphagia. Computed tomography revealed osteophytes on the second and third thoracic vertebrae and free air in the mediastinum, indicating esophageal perforation. Emergent surgery was performed. Intraoperatively, a longitudinal esophageal tear was identified. We stress the importance of being aware of the possibility of osteophyte-related esophageal perforation in patients with a history of a fall. A delayed diagnosis affects the prognosis.

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.
RESUMEN
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.

This case involved a 27-year-old man with extreme obesity (body mass index 45.6 kg/m2) who had a history of fulminant hepatitis and living-donor liver transplantation at 11 years of age. He had been receiving oral sustained-release tacrolimus (TAC) 1.5 mg daily, and the trough concentration in the blood was below 2.0 ng/mL. He has an intrinsic cytochrome P450 3A5 (CYP3A5)*3/*3 (G/G) genotype and graft liver with CYP3A5*3 allele donated by his biological father. Additionally, there were no data on the phenotype of P-glycoprotein. He did not take medications, grapefruit, or St. John's wort, which interact with CYP3A4 and P-glycoprotein. He intentionally took 30 mg of TAC and presented with symptoms of general malaise and poisoning. On the day of hospitalization (day 0), TAC was discontinued due to an elevated blood TAC concentration of > 60 ng/mL. Additionally, the blood TAC concentration exceeded 10 ng/mL for more than 3 days. He exhibited mild elevation of alanine aminotransferase, aspartate aminotransferase, and creatinine phosphokinase without apparent clinical symptoms. After discharge, blood TAC concentration decreased to 7.4 and 3.7 ng/mL on days 14 and 28, respectively, from the day of excessive TAC intake. Finally, the blood TAC concentration fell below 2.0 ng/mL on day 66. This case report showed that extreme obesity and the liver CYP3A5*3 allele delayed the elimination of TAC after excessive intake of the drug.

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.
RESUMEN
INTRODUCTION: Sepsis is not only the leading cause of death in the intensive care unit (ICU) but also a major risk factor for physical and cognitive impairment and mental disorders, known as postintensive care syndrome (PICS), reduced health-related quality of life (HRQoL) and even mental health disorders in patient families (PICS-family; PICS-F). The ABCDEF bundle is strongly recommended to overcome them, while the association between implementing the bundle and the long-term outcomes is also unknown. METHODS AND ANALYSIS: This is a multicentre prospective observational study at 26 ICUs. All consecutive patients between 1 November 2020 and 30 April 2022, who are 18 years old or older and expected to stay in an ICU for more than 48 hours due to sepsis or septic shock, are enrolled. Follow-up to evaluate survival and PICS/ PICS-F will be performed at 3, 6 and 12 months and additionally every 6 months up to 5 years after hospital discharge. Primary outcomes include survival at 12 months, which is the primary outcome, and the incidence of PICS defined as the presence of any physical impairment, cognitive impairment or mental disorders. PICS assessment scores, HRQoL and employment status are evaluated. The association between the implementation rate for the ABCDEF bundle and for each of the individual elements and long-term outcomes will be evaluated. The PICS-F, defined as the presence of mental disorders, and HRQoL of the family is also assessed. Additional analyses with data up to 5 years follow-up are planned. ETHICS AND DISSEMINATION: This study received ethics approvals from Saiseikai Utsunomiya Hospital (2020-42) and all other participating institutions and was registered in the University Hospital Medical Information Network Clinical Trials Registry. Informed consent will be obtained from all patients. The findings will be published in peer-reviewed journals and presented at scientific conferences. TRIAL REGISTRATION NUMBER: UMIN000041433.

Extracorporeal cardiopulmonary resuscitation (ECPR) with extracorporeal membrane oxygenation is a more promising treatment for out-of-hospital cardiac arrest (OHCA) than conventional cardiopulmonary resuscitation (CCPR). However, previous studies that compared ECPR and CCPR included mixed groups of patients with or without target temperature management (TTM). In this study, we compared the neurological outcomes of OHCA between ECPR and CCPR with TTM in all patients. We performed retrospective subanalyses of the Japanese Association for Acute Medicine OHCA registry. Witnessed adult cases of cardiogenic OHCA treated with TTM were eligible for this study. We used univariate and multivariable analyses in all eligible patients to compare the neurological outcomes after ECPR or CCPR. We also conducted propensity score analyses of all patients and according to the interval from witnessed OHCA to reaching the target temperature (IWT) of ≤600, ≤480, ≤360, ≤240, and ≤120 minutes. We analyzed 1146 cases. The propensity score analysis did not show a significant difference in favorable neurological outcomes (defined as a Glasgow-Pittsburgh Cerebral Performance Category of 1-2 at 1 month after collapse) between EPCR and CCPR (odds ratio: OR 4.683 [95% confidence interval: CI 0.859-25.535], p = 0.747). However, ECPR was associated with more favorable neurological outcomes in patients with IWT of ≤600 minutes (OR 7.089 [95% CI 1.091-46.061], p = 0.406), ≤480 minutes (OR 10.492 [95% CI 1.534-71.773], p = 0.0168), ≤360 minutes (OR 17.573 [95% CI 2.486-124.233], p = 0.0042), ≤240 minutes (OR 38.908 [95% CI 5.045-300.089], p = 0.0005), and ≤120 minutes (OR 200.390 [95% CI 23.730-1692.211], p < 0.001). This study revealed significant differences in the neurological outcomes between ECPR and CCPR in patients with TTM whose IWT was ≤600 minutes.
