Real-time breath recognition by movies from a small drone landing on victim's bodies.

In local and global disaster scenes, rapid recognition of victims' breathing is vital. It is unclear whether the footage transmitted from small drones can enable medical providers to detect breathing. This study investigated the ability of small drones to evaluate breathing correctly after landing on victims' bodies and hovering over them.

Comparison of Chest Compression Quality Using Wing Boards versus Walking Next to a Moving Stretcher: A Randomized Crossover Simulation Study.

Background: When a rescuer walks alongside a stretcher and compresses the patient's chest, the rescuer produces low-quality chest compressions. We hypothesized that a stretcher equipped with wing boards allows for better chest compressions than the conventional method.

Methods: In this prospective, randomized, crossover study, we enrolled 45 medical workers and students.

Sensitive quantification of BB-22 and its metabolite BB-22 3-carboxyindole, and characterization of new metabolites in authentic urine and/or serum specimens obtained from three individuals by LC-QTRAP-MS/MS and high-resolution LC-Orbitrap-MS/MS.

Purpose: A synthetic cannabinoid BB-22 and its metabolite BB-22 3-carboxyindole have not yet been quantified in human urine. The aim of this study is to establish a sensitive analytical method for the quantification of BB-22 and its 3-carboxyindole in human serum and urine specimens, and the characterization of the unreported metabolites of BB-22 in authentic urine specimens from three individuals.

Methods: These compounds were extracted from β-glucuronide-hydrolyzed and unhydrolyzed urine and/or serum via liquid-liquid extraction.

Factors associated with fluorine-18-fluorodeoxyglucose uptake in benign thyroid nodules.

Thyroid nodules that exhibit focal uptake of fluorine-18 ((18)F)-fluorodeoxyglucose (FDG) are relatively frequent. Although the clinical features and associated mechanisms of FDG-avid lesions in both thyroid cancer and cytologically indeterminate nodules have been extensively studied, not much information is available on benign nodules. Therefore, in this retrospective study, the clinical, serological, and sonographic features of 15 benign FDG-avid nodules were compared with those of 17 non-avid lesions.

Non-islet cell tumor-induced hypoglycemia associated with macronodular pulmonary metastases from poorly differentiated thyroid carcinoma.

Background: Non-islet cell tumor-induced hypoglycemia (NICTH), a major cause of fasting hypoglycemia, is caused by the overproduction of incompletely processed, high molecular-weight insulin-like growth factor-II (IGF-II), termed "big" IGF-II. To the best of our knowledge, only two cases of thyroid carcinoma associated with NICTH have been documented.

Patient Findings: We report the case of a 72-year-old woman who was brought to the emergency department with impaired consciousness.

A comparison of Ringer's lactate and acetate solutions and resuscitative effects on splanchnic dysoxia in patients with extensive burns.

We compared the effects of Ringer's lactate (RL) and acetate (RA) solutions on parameters of splanchnic dysoxia such as PgCO(2) (PCO(2) of gastric mucosa) and pH(i) (pH of gastric mucosa) using a gastric tonometer, in addition to blood markers such as the serum arterial level of lactate, base excess, ketone body ratio, and antithrombin during the first 72h of the resuscitation period in patients with burns covering 30% or more of their body surface. A prospective study was conducted in the university tertiary referral centers. There were no significant differences in the average age, TBSA (total burn surface area), and resuscitative fluid volume during the first and second 24h between the two groups.

[Neuroendocrine response to critical illness and nutritional pharmacology].

Injury and infection produce significant alterations in metabolic homeostasis. Host humoral factors, such as the counterregulatory hormones epinephrine, cortisol, and glucagons, play important roles in metabolic changes postinjury. Hyperglycemia associated with insulin resistance is common in critically ill patients, even those who have an uneventful course postinjury.

Enhanced secretion of tissue plasminogen activator by simultaneous use of retinoic acid and ascorbic acid from tissue cultured gastroepiploic artery.

Tissue-type plasminogen activator (tPA) is a key enzyme in the fibrinolysis system and the regulation of its expression has been extensively studied in cultured vascular endothelial cells. Many kinds of supplements including growth factors are needed, however, to keep endothelial cells viable, which leads the culture condition far from the physiological milieu. Using a new device of amorphous calcium phosphate coated culture plate, we succeeded in culturing ring-cut gastroepiploic artery in a basic medium of RPMI 1640 containing 10% fetal calf serum.
