[PMID: 38778802 PMCID: PMC11109003 DOI: 10.1016/j.resplu.2024.100660] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 04/18/2024] [Accepted: 04/30/2024] [Indexed: 05/25/2024] Open
Abstract
Background Agonal breathing is a relatively common symptom that follows cardiac arrest when the brainstem function is preserved. Agonal breathing is associated with favorable survival in patients experiencing out-of-hospital cardiac arrest (OHCA). While previous studies focused on agonal breathing observed in the pre-hospital setting for all study subjects, we focused on agonal breathing observed upon hospital arrival. In this multicenter prospective study, we aimed to assess the prognosis of patients exhibiting agonal breathing upon hospital arrival were compared. We hypothesized that agonal breathing at hospital arrival would be associated with favorable neurological outcomes among patients with OHCA. Methods The data on incidence of agonal breathing were prospectively collected for all evaluable participants in a multicenter, observational study in Japan (SOS-KANTO [Survey of Survivors after Out-of-Hospital Cardiac Arrest in Kanto Area] 2017 Study). Groups with and without agonal breathing were compared upon hospital arrival. Propensity-score with inverse probability of treatment weighting (IPTW) analysis was performed to adjust for confounding factors. The primary outcome was a favorable neurological outcome (Cerebral Performance Category 1-2) at 1 month. Results A total of 6,457 participants out of the 9,909 registered in SOS-KANTO 2017 (in which 42 facilities participated) were selected for the current study. There were 128 patients (2.0%) in the with-agonal breathing group and 6,329 (98.0%) in the withoutagonal breathing group. The primary outcome was 1.1% in the with-agonal breathing group and 0.6% in the without-agonal breathing group (risk difference, 0.55; 95% confidence interval, 0.23-0.87) after IPTW analysis. Conclusion In this multicenter prospective study, agonal breathing at hospital arrival was significantly associated with better neurological outcomes and increased survival at 1 month. Thus, agonal breathing at hospital arrival may be a useful prognostic predictor for patients experiencing OHCA.

Abstract
BACKGROUND Repeated triage training is necessary to maintain and improve the accuracy of simple triage and rapid treatment (START), a popular triage method. Virtual reality (VR) may be more effective than conventional training methods. This study aimed to verify the educational usefulness of START using VR originally developed for students. METHODS A VR was initially developed with a function that allowed students to select the triage procedure and its evaluation. Triage was performed using a simple modified START method, and eight scenarios were developed. The participants included 70 paramedic students classified into VR and live lecture groups. They took a 20-question written test that evaluated their academic ability before the course. After the course, a practical test and a 20-question written test were conducted. The total score of the practical test was 43 points. Triage procedure (1 point), observation and evaluation (1-5 points), and triage categories (1 point) were evaluated in this test. RESULTS The VR and live lecture groups consisted of 33 and 29 participants, respectively. No significant differences were observed pre- and post-test. In the practical test, the median (interquartile range) score was 29 (26-32) and 25 (23-29) for the VR and live lecture groups, respectively, with the VR group scoring significantly higher (P=0.03). CONCLUSION Our results confirmed the educational usefulness of selective VR for active learning of START. Therefore, VR combined with live lectures and simulations would be an optimal educational technique.

Abstract
BACKGROUND Trauma is a serious medical and economic problem worldwide, and patients with trauma injuries have a poor survival rate following cardiac arrest. This study aimed to create a prediction model specific to prehospital trauma care and to achieve greater accuracy with techniques of machine learning. METHODS This retrospective observational study investigated data of patients who had blunt trauma injuries due to traffic accident and fall trauma from January 1, 2018, to December 31, 2019, using the National Emergency Medical Services Information System, which stores emergency medical service activity records nationwide in the United States. Random forest was used to develop a machine learning model. RESULTS Per the prediction model, the area under the curve of the predictive model was 0.95 and negative predictive value was 0.99. The feature importance of the predictive model was the highest for the AVPU scale (an acronym from "Alert, Verbal, Pain, Unresponsive"), followed by oxygen saturation (SpO2). Among patients who were progressing to cardiac arrest, the cutoff value was 89% for SpO2 in unalert patients. CONCLUSIONS Patients whose conditions did not progress to cardiac arrest could be identified with high accuracy by machine learning model techniques.

Abstract
BACKGROUND In Japan, increasing the number of ambulance requests, the case with the use of respiratory assistance devices in prehospital care by paramedics is also increasing. When patient experiences respiratory failure, the first responders frequently select a respiratory assist device (RAD) such as Bag Valve Mask (BVM), Jackson Rees (JR), or BVM with Gas Supply Valve® (BVM+GSV). This is based on both evaluation and experience as there is no study indicating which RAD is the best choice at the pre-hospital emergency site. This study clarified the precautions when using BVM, JR, and BVM+GSV in pre-hospital emergency medical care with healthy volunteers. METHODS Twenty healthy adults were fitted with a RAD while breathing spontaneously, and changes in vital signs and ETCO2 were observed. RESULTS The level of ETCO2 became elevated after each RAD was attached. The value was significantly higher in the JR group than in the others. CONCLUSIONS The study showed that even in the presence of spontaneous breathing, ETCO2 increased markedly with the application of respiratory assist devices that are used in pre-hospital care for conditions such as hypoxemia and ventilatory disturbance. The increase in ETCO2 was particularly significant in the JR group, suggesting the need for caution when selecting JRs for pre-hospital care. As the number of subjects was only 20 for each RAD, studies with a larger sample size are needed.

Evaluation of outcomes after EMS-witnessed traumatic out-of-hospital cardiac arrest caused by traffic collisions. Resuscitation 2021; 171:64-70. [PMID: 34958879 DOI: 10.1016/j.resuscitation.2021.12.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 12/02/2021] [Accepted: 12/21/2021] [Indexed: 10/19/2022]
Abstract
AIM The survival rate of patients with traumatic cardiac arrest is 3 % or lower. Cardiac arrest witnessed by emergency medical services (EMS) accounts for approximately 16% of prehospital traumatic cardiac arrests, but the prognosis is unknown. We aimed to compare the 1-month survival rate of cardiac arrest witnessed by EMS with that of cardiac arrest witnessed by bystanders and unwitnessed cardiac arrest in traffic trauma victims; further, the time from injury to cardiac arrest was assessed. METHODS This analysis used the Utstein Registry in Japan and included data of 3883 patients with traumatic cardiac arrest caused by traffic collisions registered between 2014 and 2019 in Japan. RESULTS The 1-month survival rate was 10.9 % in the EMS-witnessed cardiac arrest group; this was significantly higher than that in the bystander-witnessed (7.2 %) and unwitnessed (5.6 %) cardiac arrest groups (P<0.01). The median time from injury to cardiac arrest was 18 min (25% quartile: 12, 75% quartile: 26). CONCLUSION The 1-month survival rate was significantly higher in the EMS-witnessed cardiac arrest group than in the bystander-witnessed and unwitnessed cardiac arrest groups. It is important to prevent progression to cardiac arrest in trauma patients with intact respiratory function and pulse rate at the time of contact with EMS. A system for early recognition of severe trauma is needed, and a doctor's car or helicopter can be requested as needed. We believe that early recognition and prompt intervention will improve the prognosis of prehospital traumatic cardiac arrest.

Abstract
Abstract
Background: In recent years, anti-PD-1 antibody, an immune checkpoint inhibitor, has been developed for the treatment of various types of cancer, including breast cancer. Synergistic effects of nivolumab, paclitaxel and bevacizumab are expected, based on various preclinical data, when these drugs are administered in combination. A biomarker study is ongoing to evaluate the immune status of patients participating in the NEWBEAT trial, which is a phase II trial of nivolumab + paclitaxel + bevacizumab therapy as first-line treatment for patients with metastatic or recurrent HER2-negative breast cancer. Methods: HER2-negative breast cancer patients from the WJOG9917B (NEWBEAT) trial are enrolled in this biomarker study. To explore new biomarkers for combined treatment of breast cancer with immune-checkpoint inhibitors and anti-vascular endothelial growth factor antibodies, we propose to conduct multicolor immunohistochemistry (IHC) assays for immunomonitoring of the intra-tumor environment, such as the expressions of PD-L1, CD4 and CD8. Blood samples are collected before the start of treatment and at four time-points during the treatment, to determine, using a multicolor flow cytometry panel, the numbers of circulating immunosuppressive cells, such as regulatory T cells, myeloid-derived suppressor cells and tumor-associated macrophages (M2). In the NEWBEAT trial, patients receive nivolumab 240 mg/body on days 1 and 15, paclitaxel 90 mg/m2 on days 1, 8 and 15, and bevacizumab 10 mg/kg on days 1 and 15 every 4 weeks until disease progression. The primary endpoint is the objective response rate, and the key secondary endpoints include progression-free survival, overall survival, and toxicity of the protocol treatment. A total of 51 patients will be enrolled and the enrollment period will be one year. This trial opened to accrual in February 2018. Clinical trial registry number: UMIN000029590

Abstract
Ordered mesoporous thin films of TiO2 and CexZr1-xO2 (x = 0, 0.5, 1) were prepared via an evaporation-induced self-assembly (EISA) process and subsequently investigated in terms of the developing intrinsic and residual in-plane stress. These mechanical properties were determined by the curvature method, which is based on the determination of the deflection of light due to concave or convex bending of the films on a substrate. The films were investigated with regard to the intrinsic stress during heat treatment up to 500 °C and to the residual stress at room temperature for several annealing temperatures. Following this strategy, the influence of the decomposition of a block copolymer template on the intrinsic stress as well as the pore collapsing on the residual stress was analyzed. Nanoporous TiO2 thin films were prepared using two different block copolymers (PIB50-b-PEO45 and Pluronic® F127). A comparison between the templated and non-templated TiO2 films showed the lowest intrinsic and residual stress for the ordered mesoporous material prepared with PIB50-b-PEO45 indicating that the distributed polymer and the corresponding mesopores act as relaxing agents for the system. This was verified by mesoporous CexZr1-xO2 (x = 0, 0.5, 1) thin films showing a comparable behavior in terms of the experienced intrinsic stress. This work reveals an increase in the residual in-plane stress during pore collapse, which lays the foundation for further understanding of the stress-related mechanical properties of mesoporous thin films.

Abstract
BACKGROUND Mogamulizumab (Mog) is a defucosylated, therapeutic monoclonal antibody, targeting CCR4 and was first approved in Japan for the treatment of adult T-cell leukaemia/lymphoma (ATLL), followed by cutaneous T-cell lymphoma and peripheral T-cell lymphoma. OBJECTIVE To retrospectively investigate development of photosensitivity in patients with mycosis fungoides and other T-cell neoplasms after treatment with Mog. METHODS We treated seven cutaneous lymphoma patients with Mog. Upon combination treatment with narrow-band UVB, we noticed that four patients developed photosensitivity dermatitis following Mog therapy, including two cases of mycosis fungoides, one case of adult T-cell leukaemia/lymphoma and one case of EB virus-associated T-cell lymphoproliferative disorder. Phototest was performed with UVA and UVB, and immunohistochemical staining for CD4, CD8 and Foxp3 was conducted in both photosensitivity and lymphoma lesions. RESULTS Phototest revealed that the action spectrum of the photosensitivity was UVB in three cases and both UVB and UVA in one case. Histopathologically, the photosensitive lesions were characterized by a lichenoid tissue reaction with a CD8+ T cell-dominant infiltrate, sharing the feature with chronic actinic dermatitis, an autoreactive photodermatosis with a cytotoxic T-cell response. Foxp3+ regulatory T cells (Tregs) were decreased in the photosensitivity lesions compared with the lymphoma lesions. CONCLUSION Increased incidence of photosensitivity reaction was observed during Mog treatment. Decreased number of Tregs in the lesional skin suggests that this reaction is possibly induced by autoreactive cytotoxic T cells.

Abstract
Abstract
Background
Immune checkpoint therapy only benefits a fraction of patients, thus huge efforts have been made to develop predictive biomarkers to identify those patients. Immune biomarkers like PD-L1 expression are extremely dynamic and the timing of evaluation, on primary or metastatic disease, may be critical. We have already shown that tumour-infiltrating lymphocytes (TILs) decrease during metastatic progression in triple-negative (TN) and human epidermal growth factor-2 positive (HER2+) breast cancers (Ogiya R, ASCO 2015), suggesting that mechanisms of immune escape contribute and favour the metastatic progression. In this work we aimed to characterize the modulation and changes of specific immune markers during the metastatic spread comparing paired samples from primary and recurrent breast cancers.
Methods
We retrospectively identified 25 patients with HER2+ (n = 14) and TN (n = 11) early breast cancer diagnosed between 1990 and 2009 at Tokai University Hospital, and who subsequently experienced a first regional or distant recurrence confirmed by tumour biopsy/resection. Haematoxylin and eosin-stained slides of these paired samples were evaluated for stromal TILs. Immunohistochemical staining was performed using primary antibodies against CD4, CD8, Foxp3, PD-L1, PD-L2, and HLA-class I.
Results
The sites of first recurrence was the skin (n = 7), brain (n = 6), lymph node (n = 4), lung (n = 3), bone (n = 2), and one of each of bone marrow, liver and muscle. Immunohistochemical evaluations could not be performed in 5 primary tumours and 2 recurrent tumours because of the small quantity of the specimens. The percentage of CD8+ T cells staining in the primary tumours was significantly higher (median 16%) than that in recurrent tumours (median 10%) (paired t-test, p = 0.008) Similarly, the percentage of CD4+ T cells staining in the primary tumours was significantly higher (median 40%) than that in recurrent tumours (median 25%) (p = 0.026). The percentage of Foxp3+ T cells was low (<10%) and similar in both primary and recurrent tumours (p = 0.16). PD-L1, PD-L2, and HLA class I antibody expression was not statistically different between primary and recurrent tumours, but conversions from positive to negative and vice versa were observed. PD-L1+ staining (≥1%) was 90% and 85% in primary and metastatic tumours, respectively.

Tumours at first metastatic recurrence in HER2+ and TN breast cancers have a lower percentage of both CD8+ and CD4+ T cells compared to primary tumours, confirming a potential role of immune escape in tumour progression. Other immune markers, including PD-L1, were not found to change significantly, but negative/positive conversions were observed. This suggest that an evaluation of disease at the time of immunotherapy administration might be more informative. These findings warrant larger confirmation studies.

Clinical Utility of Diagnostic Laboratory Tests in Dogs with Acute Pancreatitis: A Retrospective Investigation in a Primary Care Hospital. J Vet Intern Med 2015; 30:116-22.

Abstract
BACKGROUND Acute pancreatitis (AP) occurs frequently in dogs, but most previous studies examining the diagnosis of AP have used data from secondary care hospitals. HYPOTHESIS/OBJECTIVES The aim of this study was to investigate the clinical utility of diagnostic laboratory tests in dogs with AP in a primary care hospital. ANIMALS Sixty-four dogs with clinical signs suggestive of AP diagnosed with nonpancreatic disease (NP) or AP. METHODS Medical records were retrospectively reviewed, including diagnostic laboratory tests considered potentially useful in the diagnosis of AP. The diagnostic accuracy of amylase and FUJI DRI-CHEM lipase (FDC lip) were investigated using receiver operating characteristics (ROC). In addition, we verified whether diagnostic laboratory tests were useful for evaluating duration of hospitalization and as biomarkers for monitoring recovery. RESULTS Activities of amylase and FDC lip were significantly higher in the AP group than in the NP group (P = .001, P < .001, respectively). The sensitivity of FDP lip activity for diagnosing AP was 100% (95% confidence interval [CI], 87.7-100%); the specificity was 89.5% (95% CI, 66.9-98.7%). Area under the ROC curve for FDC lip activity was 0.98 (95% CI, 0.93-1). High alanine aminotransferase (ALT) activity was associated with extended duration of hospitalization (P = .04). A significant difference in C-reactive protein (CRP) concentration before and 5 days after treatment was found (P = .001). CONCLUSIONS AND CLINICAL IMPORTANCE Measurement of FDC lip activity appears useful for diagnosing AP. High ALT activity might be associated with prolonged duration of hospitalization, and CRP might be useful as a biomarker for monitoring recovery from AP.

Abstract
Renal handling of Na and Ca in response to physiological saline infusion (20 ml/kg i.v. for 2 h) was compared between 27 hypertensive (mean +/- SD age 79.8 +/- 9.2 years) and 44 normotensive (79.1 +/- 4.1 years) senile females. Compared to the normotensive group, the hypertensive group showed statistically significant decreases in the basal values of serum Ca and PRA, and significant increases in basal circulating levels of parathyroid hormone and 1,25(OH)2D and in urinary excretions of Na, Ca and Pi in the 2-hour urine specimens during the saline infusion. These results suggest that the excessive excretions of Ca and Pi associated with exaggerated natriuresis may participate in aberration of Ca metabolism in low-renin hypertensive seniles.
