Epidemiology and Assessment of Traumatic Spinal Cord Injury With Concomitant Brain Injury: An Observational Study in a Regional Trauma Center.

Objective: : To analyze the epidemiological information of patients with traumatic spinal cord injury (SCI) and concomitant traumatic brain injury (TBI) and to suggest points to be aware of during the initial physical examination of patients with SCI.

Methods: : This study was a retrospective, observational study conducted in a regional trauma center. All the records of patients diagnosed with traumatic SCI between 2016 and 2020 were reviewed.

Effects of Thermal Conductive Materials on the Freeze-Thaw Resistance of Concrete.

To solve the problem of black ice, many studies are being carried out. The key in recent days is enhancing the thermal conductivity of concrete. In this study, to improve the thermal conductivity, silicon carbide was used to substitute 50% and 100% of the fine aggregate.

Evaluation of the Hydration Characteristics and Anti-Washout Resistance of Non-Dispersible Underwater Concrete with Nano-SiO and MgO.

In this paper, the effect of nano-SiO (NS) and MgO on the hydration characteristics and anti-washout resistance of non-dispersible underwater concrete (UWC) was evaluated. A slump flow test, a viscosity test, and setting time measurement were conducted to identify the impacts of NS and MgO on the rheological properties of UWC. The pH and turbidity were measured to investigate the anti-washout performance of UWC mixes.

Identification of acquired tracheoesophageal fistula after tracheostomy decannulation by videofluoroscopic swallowing study: A case report.

Rationale: Videofluoroscopic swallowing study (VFSS) is a noninvasive radiographic procedure that examines the oral, pharyngeal, and cervical esophageal stages of swallowing. Tracheoesophageal fistula (TEF) is difficult to diagnose depending on its size and location. However, how VFSS can be of benefit in the diagnosis of TEF has not been reported yet.

GSTM1 and TNF-alpha gene polymorphisms and relations between blood lead and inflammatory markers in a non-occupational population.

Inflammation is known to be an important underlying condition in the development of a variety of diseases. To investigate whether blood lead induces inflammatory reactions in non-occupationally exposed adults and the effects of genetic susceptibility associated with GSTM1 and TNF-alpha gene polymorphisms on this inflammatory response, we measured blood lead levels in 300 healthy university students. Total serum TNF-alpha and IL-6 levels and WBC counts were determined to evaluate the inflammatory response.

Effect of short-term fasting on urinary excretion of primary lipid peroxidation products and on markers of oxidative DNA damage in healthy women.

The goal of this study was to determine whether short-term fasting changes in urinary biomarkers related to oxidative stress: malondialdehyde (MDA), 8-isoprostaglandin F2alpha (8-isoPGF), 8-hydroxydeoxy-guanosine (8-OHdG) and 1,N6-ethenodeoxyadenosine (epsilondA) among female volunteers participating in the short-term fasting program in South Korea. The study subjects were 52 healthy women (mean age 28, range 15-48 years old) who provided urine samples both before and after the fasting program (average 7.2, range: 3-11 days).
