Functional safety-oriented hazard analysis and risk assessment for vehicular fuel cell systems.

Functional safety is an emerging trend for safety design in the automobile industry. This study is an innovative exploration of a hazard analysis and quantitative risk assessment (QRA) methodology based on the functional safety of vehicular fuel cell systems. In this study, the potential hazards that fuel cell vehicles may encounter during operation were identified using the automobile generic hazard list.

Risk factors for surgical site infection after patellar fracture surgery in the elderly.

Background: Patellar fractures are a common knee injury among elderly patients, with a high risk of developing surgical site infections (SSI) postoperatively, which severely affects patient prognosis and quality of life. Elderly patients are more susceptible to SSI due to various factors such as decreased immune function and chronic diseases. Therefore, identifying the risk factors for SSI is of great clinical significance for prevention.

Identifying key risk factors for acute compartment syndrome in tibial diaphysis fracture patients.

Acute compartment syndrome (ACS) is a severe orthopedic issue that, if left untreated, can result in lasting nerve and muscle damage or even necessitate amputation. The association between admission laboratory blood test indicators and the occurrence of ACS in patients with tibial diaphysis fractures is currently a subject of debate. The objective of this research was to identify the contributing factors for ACS in individuals suffering from tibial diaphysis fractures.

'Skip' osteoporosis vertebral compression fractures caused by electrical injury: a case report and review of the literature.

Introduction: Electrical injuries rarely result in fractures, such as long bone fractures and spinal fractures. A few articles have reported osteoporosis vertebral compression fractures (OVCFs) caused by electrical injuries. Here, we present a rare case of 37-year-old male suffering from the 9th thoracic (T9) and 5th lumbar (L5) OVCFs after receiving a electric shock.

Risk factors for distal junctional kyphosis after posterior spinal surgery in adolescent idiopathic scoliosis: a meta-analysis.

Introduction: Distal junctional kyphosis (DJK) is a serious complication after posterior spinal surgery in managing adolescent idiopathic scoliosis (AIS). Our study aims to investigate the predictors of DJK in AIS patients.

Methods: We searched the English databases of PubMed, Embase, and the Cochrane Library for clinical research studies on AIS.

Surgical site infection following fasciotomy in patients with acute forearm compartment syndrome: a retrospective analysis of risk factors.

Purpose: Fasciotomy, a standard therapy for acute forearm compartment syndrome (AFCS), can prevent serious complications, but there may be significant postoperative consequences. Surgical site infection (SSI) may cause fever, discomfort, and potentially fatal sepsis. This study aimed to identify risk factors for SSI in AFCS patients who had undergone fasciotomy.

Spontaneous brainstem haemorrhage in a patient with uraemia undergoing initial hemodialysis: A case report.

The present study reports the case of an elderly male inpatient with uraemia who had a sudden onset of numbness and weakness in the right limbs during sleep at night, accompanied by blurred and double vision, during the induction of haemodialysis (HD). Cranial computed tomography and magnetic resonance imaging revealed signs of brainstem haemorrhage. Consequently, a proactive treatment approach was adopted for decreasing the blood and intracranial pressures of the patient, and regular HD was continued.

Distribution Characteristics of Ground Echo Amplitude and Recognition of Signal Grazing Angle.

With the continuous advancement of electronic technology, terahertz technology has gradually been applied on radar. Since short wavelength causes severe ground clutter, this paper studies the amplitude distribution statistical characteristics of the terahertz radar clutter based on the measured data, and provides technical support for the radar clutter suppression. Clutter distribution is the function of the radar glancing angle.
