Extensive application of methylene blue (MB) for therapeutic and diagnostic purposes, and reports for unwanted side effects, demand better understanding of the mechanisms of biological action of this thiazine dye. Because MB is redox-active, its biological activities have been attributed to transfer of electrons, generation of reactive oxygen species, and antioxidant action. Results of this study show that MB is more toxic to a superoxide dismutase-deficient Escherichia coli mutant than to its SOD-proficient parent, which indicates that superoxide anion radical is involved. Incubation of E. coli with MB induced the enzymes fumarase C, SOD, nitroreductase A, and glucose-6-phosphate dehydrogenase, all controlled by the soxRS regulon. Induction of these enzymes was prevented by blocking protein synthesis with chloramphenicol and was not observed when soxRS-negative mutants were incubated with MB. These results show that MB is capable of inducing the soxRS regulon of E. coli, which plays a key role in protecting bacteria against oxidative stress and redox-cycling compounds. Irrespective of the abundance of heme-containing proteins in living cells, which are preferred acceptors of electrons from the reduced form of MB, reduction of oxygen to superoxide radical still takes place. Induction of the soxRS regulon suggests that in humans, beneficial effects of MB could be attributed to activation of redox-sensitive transcription factors like Nrf2 and FoxO. If defense systems are compromised or genes coding for protective proteins are not induced, MB would have deleterious effects.
In patients requiring emergency rapid sequence intubation (RSI), 100% oxygen is often delivered for preoxygenation to replace alveolar nitrogen with oxygen. Sometimes, however, preoxygenation devices are prematurely removed from the patient prior to the onset of apnea, which can lead to rapid loss of preoxygenation.

We sought to determine the elapsed time, on average, between removing the oxygen source and the loss of preoxygenation among non-critically ill patients in the emergency department (ED).

We conducted a prospective, crossover study of non-critically ill patients in the ED. Each patient received two identical preoxygenation trials for 4min using a non-rebreather mask with oxygen flow at flush rate and a nasal cannula with oxygen flow at 10L/min. After each preoxygenation trial, patients underwent two trials in random order while continuing spontaneous breathing 1) removal of both oxygen sources and 2) removal of non-rebreather mask with nasal cannula left in place. We defined loss of preoxygenices should be left in place until the patient is completely apneic.
Falls into small water bodies can cause drowning and trauma. Such falls, especially into irrigation canals, and the subsequent trauma are common in Japan. However, few studies have investigated their characteristics, costs, and prognosis.

Our aim was to clarify the characteristics, prognosis, and economic burden of trauma due to falls into irrigation canals in Kurashiki City, Japan.

This 4-year, single-center, retrospective cohort study was conducted at a Japanese tertiary care hospital between January 1, 2013 and December 31, 2016. We enrolled patients who had fallen into irrigation canals constructed more than 300years ago, and transported to our hospital by ambulance. The study outcomes included the characteristics, prognosis, and health care costs of such trauma.

We enrolled 266 patients with a median age of 66years (range 19-64years). Most patients fell into irrigation canals while walking (49.3%), riding a bicycle (35.0%), or driving or riding in a car (7.1%). Extremities were the most frequently affected body parts, and the head and chest were less frequently affected. Four patients (1.5%) died in the emergency department (ED), and 121 (45.5%) were hospitalized (109 in our hospital and 12 transferred to other hospitals). The total costs of ED and hospital stays were 777,625 US dollars (266 patients) and 712,059 US dollars (109 patients hospitalized in our hospital), respectively.

Trauma due to falls into irrigation canals can be severe and even fatal, and the related costs are high. Our study highlights the importance of implementing appropriate measures to prevent falls into irrigation canals and of promoting awareness among citizens.

The LUCAS (Lund University Cardiopulmonary Assist System; Physio-Control Inc./Jolife AB, Lund, Sweden) was developed for automatic chest compressions during cardiopulmonary resuscitation (CPR). Evidence on the use of this device in out-of-hospital cardiac arrest (OHCA) suggests that it should not be used routinely because it has no superior effects.

The aim of this study was to compare the effect of CPR for OHCA with and without LUCAS via a regional nonurban emergency medical service (EMS) physician-present prehospital medical system.

We analyzed a prospective registry of all consecutive OHCA patients in four EMS stations. Two of them used a LUCAS device in all CPR, and the EMS crews in the other two stations used manual CPR. Individuals with contraindication to LUCAS or with EMS-witnessed arrest were excluded.

Data from 278 patients were included in the analysis, 144 with LUCAS and 134 with manual CPR. There were more witnessed arrests in the LUCAS group (79.17% vs. 64.18%; p=0.0074) and patients in the LUCAS group were older (p = 0.03). We found no significant difference in return of spontaneous circulation (30.6% in non-LUCAS vs. 25% in LUCAS; p=0.35). In the LUCAS group, we observed significantly more conversions from nonshockable to shockable rhythm (20.7% vs. 10.10%; p=0.04). The 30-day survival rate was significantly lower in the LUCAS group (5.07% vs. 16.31% in the non-LUCAS group; p=0.044). At 180-day follow-up, we observed no significant difference (5.45% in non-LUCAS vs. AUNP-12 nmr 9.42% in LUCAS; p=0.25).

Use of the LUCAS system decreased survival rate in OHCA patients. Significantly higher 30-day mortality was seen in LUCAS-treated patients.

Portal venous gas (PVG) is a rarely observed clinical finding generally associated with intestinal ischemia. The proper clinical response to the finding of PVG depends somewhat on the setting in which it is observed. Here we describe a case in which extensive arterial gas emboli (AGE) were encountered during point-of-care ultrasound (POCUS) and subsequent computed tomography (CT) identified PVG secondary to gastric wall ischemia as the likely source.

A 69-year-old woman with history of metastatic colon cancer presented to the emergency department (ED) with altered mental status. On arrival, she was hypotensive, hypothermic, cachectic, and with abdominal distension. POCUS was performed to evaluate the source of the patient's hypotension, revealing the presence of PVG, as well as gas bubbles in all four chambers of the heart and the aorta. CT scan revealed gastric wall ischemia and confirmed the presence of significant air emboli throughout the portal venous system. Given the overall poor prognosis, the deche heart and the aorta. CT scan revealed gastric wall ischemia and confirmed the presence of significant air emboli throughout the portal venous system. Given the overall poor prognosis, the decision was made to forego further chemotherapy or surgery and the patient died later that week while under hospice care. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? AGE can occur in the setting of PVG. This may cause multi-organ failure by disrupting blood flow to organs, especially in patients with circulatory dysfunction, such as shock. Depending on the setting in which it is diagnosed, early detection of PVG may expedite earlier assessments of a patient's negative prognosis or initiation of attempted life-saving treatment. In this case report, we show that POCUS can be used to obtain an expedited diagnosis in a critically ill patient.
Diversity is an identified priority amongst governing medical bodies. We systematically analyzed public membership diversity data posted by North American radiology societies.

Two independent study members reviewed North American radiology society websites to collect public data on membership diversity, specifically related to gender, race, and sexual orientation or gender identity, and categorized data using a coding system. Supplemental searches were conducted to confirm findings. Study team members created accounts on each society website to identify whether diversity data was collected during member enrollment.

We reviewed a total of 26 society websites, with median 1500 members (range 110-54,600). We categorized five societies as "diversity leaders" based on having diversity statement(s), diversity initiatives, and diversity publication(s). While 62%, 8%, and 0% of societies collected data on gender, race, and sexual orientation or gender identity, respectively, no societies posted membership comporve as models for societies aiming to establish their commitment to diversity.
To review the clinical data, D-dimer level and the ultrasonographic findings from complete venous ultrasound of the lower extremity in deep venous thrombosis (DVT)-unlikely patients with abnormal D-dimer test were compared to DVT-likely patients to ascertain the appropriate ultrasound examination protocol for patients in this group.

A retrospective cohort study was conducted of all patients who underwent a complete (whole leg) venous ultrasound in one 13-month period. The medical history, demographic, clinical risk factors, and ultrasonographic findings of the patients with high clinical probability for deep vein thrombosis (Wells score ≥2), along with patients with a low clinical probability of deep vein thrombosis (Wells score ≤1) but with a D-dimer level higher than the threshold (≥500 ng/ml FEU) were evaluated.

There were 96 patients in the DVT-likely group and 86 patients in the DVT-unlikely group. The indication for ultrasound examination in the DVT-unlikely group was preoperative assessment to avnous ultrasound lower-extremity examinations, the use of a higher D-dimer cut-off level and limiting proximal or thigh vein ultrasound examinations in the preoperative patient is considered.
Develop a deep learning-based algorithm using the U-Net architecture to measure abdominal fat on computed tomography (CT) images.

Sequential CT images spanning the abdominal region of seven subjects were manually segmented to calculate subcutaneous fat (SAT) and visceral fat (VAT). The resulting segmentation maps of SAT and VAT were augmented using a template-based data augmentation approach to create a large dataset for neural network training. Neural network performance was evaluated on both sequential CT slices from three subjects and randomly selected CT images from the upper, central, and lower abdominal regions of 100 subjects.

Both subcutaneous and abdominal cavity segmentation images created by the two methods were highly comparable with an overall Dice similarity coefficient of 0.94. Pearson's correlation coefficients between the subcutaneous and visceral fat volumes quantified using the two methods were 0.99 and 0.99 and the overall percent residual squared error were 5.5% and 8.5%. Manual segmentation of SAT and VAT on the 555 CT slices used for testing took approximately 46 hours while automated segmentation took approximately 1 minute.
