RESUMEN
CAPA (COVID-19 associated pulmonary aspergillosis) is an important complication of COVID-19. It has been reported that the incidence of CAPA is as high as 19%-33% worldwide. However, its onset has not been reported in Japan. A 72-year-old Japanese man was diagnosed with COVID-19 and was transferred to our hospital due to deterioration of respiratory condition. Treatment with remdesivir, dexamethasone (DEXA), and antibiotics was performed under mechanical ventilation. Although the condition improved temporarily, a new shadow appeared in the lung, and Aspergillus fumigatus was cultured from sputum. The patient was clinically diagnosed with CAPA and treated with voriconazole. However, his progress deteriorated and he died. High-risk COVID-19 patients should be tested for Aspergillus to ensure early diagnosis of CAPA.

Aim: Coronavirus disease (COVID-19) spread worldwide, and was declared as a pandemic by the World Health Organization. Despite numerous studies in the last few years, the factors associated with the outcomes of patients with COVID-19 requiring mechanical ventilation remain unclear. The prediction of ventilator weaning and mortality using the data obtained at the time of intubation could be beneficial for establishing appropriate treatment strategies and obtaining informed consent. In this study, we aimed to clarify the association between patient information at the time of intubation and the outcomes of intubated COVID-19 patients. Methods: This retrospective observational study used single-center data from patients with COVID-19. Patients with COVID-19 who were admitted to Osaka Metropolitan University Hospital from April 1, 2020, to March 31, 2022, and under mechanical ventilation were included. The main outcome was defined as the factors related to ventilator weaning; a multivariate analysis was carried out to evaluate the association between patient information at the time of intubation and the outcome. Results: In total, 146 patients were included in this study. The factors significantly associated with ventilator weaning were age (65-74 years old, adjusted odds ratio [OR], 0.168; 75 years and older, adjusted OR, 0.121), vaccination history (adjusted OR, 5.655), and Sequential Organ Failure Assessment (SOFA) respiration score (adjusted OR, 0.007) at the time of intubation. Conclusion: Age, SOFA respiration score, and COVID-19 vaccination history at the time of intubation could be associated with outcomes in patients with COVID-19 requiring mechanical ventilation.
RESUMEN
Introduction: The telephone triage service is an emergency medical system through which citizens consult telephone triage nurses regarding illness, and the nurses determine the urgency and need for an ambulance. Despite being introduced in several countries, its impact on emergency patients has not been reported. We aimed to determine the effect of the telephone triage service on the outcomes of hospitalized patients diagnosed with cerebrovascular disease upon arrival after being transported by an ambulance. Methods: This retrospective study included patients with cerebrovascular disease who were transported by ambulance between January 2016 and December 2019. The primary outcome was discharge to home by day 21 of hospitalization. A total of 344 patients who used the telephone triage service were propensity score-matched to 344 patients who directly called for an ambulance. Results: Telephone triage service use was associated with discharge to home by hospital day 21 (crude odd ratio: 1.8; 95% confidence interval: 1.3-2.4) and was not significantly associated with survival on hospital day 21 in multivariate regression analysis. Conclusion: The prognoses of cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage depend on the time from symptom onset to treatment. Telephone triage services may allow patients to receive treatment more rapidly than traditional ambulance requests, resulting in improved patient outcomes. The findings of this study suggest that the use of telephone triage services is associated with improved outcomes in patients with cerebrovascular disease and indicate that the costs for medical expenses and disability may be greatly reduced in an aging society.

Objectives: Severe pelvic fracture concomitant with massive bleeding is potentially lethal, and intervention for hemorrhage control still depends on institutional supplies. With the recent installation of a CT and C-arm combined resuscitation room system (CTCARM) for treatment of trauma patients in our institution, the strategic process and options for hemorrhage control after pelvic fracture have changed. We retrospectively reviewed the procedures we performed and their outcomes. Methods: The CTCARM was installed in our trauma resuscitation room in April 2020. Patients who were diagnosed as having pelvic fracture and underwent interventional radiology for hemorrhage control within 2.5 hours after arrival were compared before and after CTCARM installation. We reviewed the time process for hemorrhage control, treatment options performed, blood products used and their outcomes. Results: Included in this study were 56 patients treated between 2016 and 2022, of whom 36 patients were treated before (original group) and 20 patients after CTCARM installation (CTCARM group). Patient characteristics and vital signs at admission were not statistically different. Preperitoneal pelvic packing was performed significantly more frequently in the original group (p<0.01), whereas resuscitative endovascular balloon occlusion of the aorta use was much more frequent in the CTCARM group (p=0.02). Although the times from admission to first angiography (p=0.014) and to complete hemostasis (p=0.02) were significantly shorter in the CTCARM group, mortality was not statistically different. Four preventable trauma deaths occurred in the original group, but there were none in the CTCARM group. Six unexpected survivors were observed in the original group and four in the CTCARM group. Conclusions: Although the CTCARM had no direct effects on patient mortality for now, it has allowed us to accelerate the treatment time process, shorten preperitoneal pelvic packing procedural time, and potentially avoid subsequent preventable trauma deaths. Level of evidence: Level IV.
RESUMEN
Background: Telephone triage service in emergency care has been introduced around the world, but the impact of this service on the emergency medical service (EMS) system has not been fully revealed. The aim of this study was to evaluate the effect of telephone triage service for emergency patients on decreasing unnecessary ambulance use by analysis with propensity score (PS) matching. Methods: This study was a retrospective observational study, and the study period was the 4 years from January 2016 to December 2019. We included cases for which ambulances were dispatched from the Osaka Municipal Fire Department (OMFD). The primary outcome of this study was unnecessary ambulance use. We calculated a PS by fitting a logistic regression model to adjust for 10 variables that existed before use of the telephone triage service. To ensure the robustness of this analysis, we used not only PS matching but also a multivariable logistic regression model and regression model with PS as a covariate. Results: This study included 868,548 cases, of which 8,828 (1.0%) used telephone triage services and 859,720 (99.0%) did not use this service. Use of the telephone triage service was inversely associated with the occurrence of unnecessary ambulance use in multivariate logistic regression model (adjusted OR 0.453, 95% CI 0.405-0.506) and multivariate logistic regression model with PS as a covariate (adjusted OR 0.514, 95% CI 0.460-0.574). In the PS matching model, we also revealed same results (crude OR 0.487, 95% CI 0.425-0.588). Conclusions: In this study, we were able to statistically evaluate the effectiveness of telephone triage service already in use by the public using the statistical method with PS. As a result, it was revealed that the use of a telephone triage service was associated with a lower proportion of unnecessary ambulance use in a metropolitan area of Japan.

OBJECTIVE: Telephone triage service in emergency care has been introduced in many countries, and it is important to determine the effect of telephone triage service on the outcome of emergency patients. The aim of this study was to evaluate the effect of telephone triage service on the outcome of emergency patients using propensity score. METHODS DESIGN, SETTINGS, AND PARTICIPANTS: This was a retrospective study with a study period from January 2016 to December 2019. We included all patients transported by ambulances of the Osaka Municipal Fire Department during study period. EXPOSURE: Telephone triage service. OUTCOME MEASURES AND ANALYSIS: The main outcome of this study was unfavorable outcome following use of the telephone triage service. In this study, unfavorable outcome was defined as patients who were admitted, transferred, or died after care in the emergency department. Propensity scores were calculated using a logistic regression model with 12 variables that were present before the telephone triage service was used or were indicative of the patient's condition. Data analyses were not only propensity score matching but also a multivariable logistic regression model and regression model with propensity score as a covariate. MAIN RESULTS: The number of patients eligible for analyses was 707 474. Of these patients, 8008 (1.0%) used the telephone triage services and 699 466 patients (99.0%) did not use it. The number of patients with an unfavorable outcome was 407 568 (57.6%) in the total cohort. Of them, 2305 patients (28.8%) used the telephone triage service and 297 601 patients (42.5%) did not use it. For propensity score matching, 8008 patients were matched from each group. Use of the telephone triage service was inversely associated with unfavorable outcome in a multivariate logistic regression model with propensity score as a covariate [adjusted odds ratio (OR) 0.874; 95% confidence interval (CI), 0.831-0.919] and propensity score matching (crude OR, 0.875; 95% CI, 0.818-0.936). CONCLUSIONS: This study revealed that the use of the telephone triage service in Osaka city, Japan was associated with better outcomes of patients transported by ambulance.

A 73-year-old man previously treated with rituximab for his mucosa-associated lymphoid tissue lymphoma suffered a suboptimal humoral immune response against an acquired SARS-CoV-2 infection. A detailed serological description revealed discrepant antigen-specific humoral immune responses. The titer of spike-targeting, "viral-neutralizing" antibodies remained below the detection level, in contrast to the anti-nucleocapsid, "binding" antibody response, which was comparable in both magnitude and kinetics. Accordingly, viral neutralizability and clearance was delayed, leading to prolonged RNAemia and persistent pneumonia. The present case highlights the need to closely monitor this unique population of recipients of B-cell-targeted therapies for their neutralizing antibody responses against SARS-CoV-2.

While there are no clear indications for body temperature control during viral infections such as COVID-19, if heat stress caused by COVID-19 leads to organ failure, then proactive body temperature regulation may be an effective treatment option.
RESUMEN
Malignant hyperthermia (MH) occurred during anesthesia with volatile inhalation anesthetics in a patient under treatment with multiple oral antipsychotic drugs and with a history of multi-acting receptor-targeted antipsychotic drug (MARTA)-induced elevation of serum creatine kinase (CK). Since the patient was considered to be at high risk for neuroleptic malignant syndrome (NMS) based on this history, differential diagnosis between MH and NMS was difficult at the time of onset. Later, the patient was found to be predisposed to MH based on abnormal high rate of the Ca2+-induced Ca2+ release (CICR). We concluded that MH was induced by the volatile inhalation anesthetics.
