Between 2008 and 2017, the American Pyrotechnics Association reported a 41% increase in revenue from firework sales, with 2017 showing $885 million US dollars in consumer sales. We sought to evaluate the epidemiology of firework-related upper extremity injuries during this 10-year period, hypothesizing that hand/upper extremity injuries from fireworks were increasing in the United States.

Observational epidemiologic assessment of a weighted cohort of patients via the National Electronic Injury Surveillance System from 2008 to 2017. The National Electronic Injury Surveillance System provides a nationwide probability sample of injuries related to consumer products based on emergency department visits collected from a cohort of about 100 US hospitals.

A total of 1,079 patients representing an estimated 41,195 firework-related upper extremity injuries presented to US emergency departments from 2008 to 2017. The number of injuries increased significantly from 2,576 in 2008 to 5,101 in 2017 (R2 = 0.85, R = 0.92, P < 0.001). A Spearman rank-order correlation determined that there was a strong, positive correlation between the increase in firework sales and the increase in injuries (rs = 0.939, P < 0.01). The overwhelming majority of firework-related injuries were seen in males (77%) aged 11 to 29 years (48%). The hand and fingers accounted for 85.8% of injuries, with the thumb being the most commonly injured body part (51.3%). Burns were the most common injury across all body sites except the wrist, where fractures were most common.

Ten-year firework-related upper extremity injuries increased, corresponding to increased consumer sales across the same period. This study provides previously absent population-level data to provide a framework for discussion among policy makers and physicians alike in an attempt to mitigate the use of fireworks and their associated upper extremity injuries.

Posterior cervical decompression and fusion (PCDF) is a procedure commonly performed to help alleviate symptoms and improve quality of life in patients experiencing cervical spondylotic myelopathy, multilevel stenosis, and cervical deformity. Although various risk factors have been linked to adverse outcomes in patients after PCDF, this is the first study that specifically explores postoperative glycemic variability and its association with adverse outcomes.

A retrospective cohort study was conducted with a total of 264 patients after PCDF procedures that had available postoperative blood glucose measurements. Patients were divided into tertiles based on their coefficient of variation as an indicator of glycemic variability. Outcomes measured included inpatient complications, length of stay (LOS), 90-day readmission, revision, and surgical site infection rates.

Results showed a significant difference in glycemic variability among tertiles with respect to LOS (P = 0.01). The average LOS for the first, serative glycemic variability and LOS, as well as 90-day readmission and surgical site infection rates after PCDF. Our results suggest that limiting fluctuations in blood glucose levels may curtail inpatient healthcare costs related to in-hospital stay. Although immediate postoperative glycemic variability is ultimately acceptable, before discharge, proper glucose management plans should be in place to help prevent adverse patient outcomes.

Severe acute respiratory syndrome coronavirus 2 is transmitted through aerosols and droplets. Nasal high-flow therapy could possibly increase the spreading of exhalates from patients. The aim of this study is to investigate whether nasal high-flow therapy affects the range of the expiratory plume compared with spontaneous breathing.

Videos and images from a schlieren optical system were analyzed during spontaneous breathing and different nasal high-flow rates.

The maximal exhalation spread was 0.99, 2.18, 2.92, and 4.1 m during spontaneous breathing, nasal high-flow of 20 L/min, nasal high-flow of 40 L/min, and nasal high-flow of 60 L/min, respectively. Spreading of the expiratory plume in the sagittal plane can completely be blocked with a surgical mask.

Nasal high-flow therapy increases the range of the expiratory air up to more than 4 meters. The risk to pick up infectious particles could be increased within this range. Attachment of a surgical mask over the nasal high-flow cannula blocks the expiratory airstream.

BTK inhibitor chemical structure Few studies have been reported in preclinical animal models. The similar physiology and anatomy between non-human primates (NHPs) and humans make NHPs valuable models for disease modeling and testing of drugs and devices. In the current study, we aimed to establish a TAC model in NHPs and characterize the structural and functional profiles of the heart after TAC. A non-absorbable suture was placed around the aorta between the brachiocephalic artery and left common carotid artery to create TAC. NHPs were divided into 2 groups according to pressure gradient (PG) the Mild Group (PG=31.01 ± 12.40 mmHg, n=3) and the Moderate Group (PG=53.00 ± 9.37 mmHg, n=4). At 4 weeks after TAC, animals in both TAC groups developed cardiac hypertrophy enlarged myocytes and increased wall thickness of the left ventricular (LV) anterior wall. Although both TAC groups had normal systolic function that was similar to a Sham Group, the Moderate Group showed diastolic dysfunction that was associated with more severe cardiac fibrosis, as evidenced by a reduced A wave velocity, large E wave velocity/A wave velocity ratio, and short isovolumic relaxation time corrected by heart rate. Furthermore, no LV arrhythmia was observed in either animal group after TAC. A diastolic dysfunction model with cardiac hypertrophy and fibrosis was successfully developed in NHPs.
