Translation, cross-cultural adaptation, reliability, and validity of the Chinese version of the intensive care unit environment stress scale for pediatric patients.

PURPOSE: There is currently a lack of understanding of children's experience in the pediatric intensive care unit (PICU) environment. Additionally, pediatric patients may experience post-PICU syndrome following discharge. Thus, we aimed to adapt and evaluate the psychometric properties of a tool specifically for use with children in the PICU. DESIGN AND METHODS: According to Brislin's Model, the Intensive Care Unit Environment Stress Scale (ICUESS) was translated both forward and backward and adapted cross-culturally. A total of 210 PICU patients were selected from four hospitals in XXX to analyze the final translated version of the questionnaire, the Pediatric Intensive Care Unit Environmental Stress Scale (PICUESS). Content validity, exploratory factor analysis (EFA) and Confirmatory Factor Analysis (CFA) were used to assess the validity, while reliability was assessed using Cronbach's alpha and split-half reliability analysis. RESULTS: For PICUESS, seven of 42 items were modified. Content validity was high (overall = 0.96, item validity = 0.8 to 1.0). Exploratory factor analysis revealed eight common factors (Kaiser-Meyer-Olkin = 0.857, significant Bartlett's test). The results of the CFA indicate that the scale model fits well across the 8 factors. The entire scale demonstrated excellent internal consistency (Cronbach's alpha = 0.934). The overall split-half reliability was 0.935. CONCLUSIONS: The Chinese version of PICUESS demonstrates good reliability and validity, making it suitable for assessing pediatric patients' perceptions of the PICU environment. PRACTICE IMPLICATIONS: The PICUESS can assist healthcare professionals in providing personalized environment care for PICU patients. It has the potential to serve as a tool for further testing and international comparisons of pediatric patients' perceptions of the PICU environment.

OBJECTIVES: To study the value of metagenomic next-generation sequencing (mNGS) in detecting intracranial Epstein-Barr virus (EBV) infection in children with hemophagocytic syndrome (HPS) with central nervous system involvement. METHODS: A retrospective analysis was performed for the cerebrospinal fluid mNGS results of 30 HPS children with central nervous system involvement, which were compared with the results of cerebrospinal fluid EBV-DNA detection and serum EBV antibody profile. The change in serum EBV-DNA copy number after treatment was used to evaluate the efficacy of targeted therapy. RESULTS: The positive rate of EBV in cerebrospinal fluid determined by mNGS was significantly higher than that of EBV-DNA in cerebrospinal fluid (100% vs 10%, P<0.001) and had no significant difference from the positive rate of serum EBV antibody profile (100% vs 93%, P>0.05). The median number of sequences determined by mNGS was 2 400, and serum EBV-DNA copy number before treatment was moderately positively correlated with the number of EBV sequences (rs=0.693, P<0.001). The multiple linear regression analysis showed that the number of sequences determined by mNGS in cerebrospinal fluid increased with the increase in serum EBV-DNA copy number before treatment (P<0.05). CONCLUSIONS: EBV-associated HPS often results in EBV-infected viral encephalitis, and mNGS can significantly increase the detection rate of EBV in cerebrospinal fluid, which may help with clinical diagnosis.

Multiple stress fractures of unilateral femur: A case report.

BACKGROUND: Stress fractures of the femoral neck are not common in clinical practice, and simultaneous stress fractures of the femoral neck and proximal femur of the unilateral femur are even more rare. We introduce a case of this type of fracture that was treated in our department, analyze the causes, and review similar stress fractures reported in the literature to provide references for the diagnosis and treatment of such conditions. CASE SUMMARY: A 62-year-old female, with a free medical history, was admitted to the hospital mainly due to pain in the right hip and worsening pain in the right thigh. The patient had no obvious history of trauma. X-ray and computed tomography showed fracture of the femoral neck and proximal femur. The patient had undergone surgery 1 year prior to address a fracture of the left proximal femur that had occurred in a traffic accident. Our first consideration was stress fracture of the femoral neck; however, simultaneous stress fractures of the femoral neck and proximal femur of the unilateral femur were seen. The femoral neck stress fracture was a tension fracture, with obvious displacement and varus deformity of the hip. Considering that the patient was an elderly female, we performed total hip arthroplasty. Follow-up X-rays showed that the stress fracture of the proximal femur had mostly healed after 3 mo. CONCLUSION: Muscle fatigue and hip varus deformity provide an anatomical basis for the occurrence of femoral neck stress fractures.
