The Direct and Indirect Costs of Treating the Victims of the 2016 Nice Terror Attacks in a Single Pediatric Hospital.

OBJECTIVE: To analyze the cost of the terror attack in Nice in a single pediatric institution. METHODS: We carried out descriptive analyses of the data coming from the Lenval University Children's Hospital of Nice database after the July 14, 2016 terror attack. The medical cost for each patient was estimated from the invoice that the hospital sent to public insurance. The indirect costs were calculated from the hospital's accounting, as the items that were previously absent or the difference between costs in 2016 versus the previous year. RESULTS: The costs total 1.56 million USD, corresponding to 2% of Lenval Hospital's 2016 annual budget. Direct medical costs represented 9% of the total cost. The indirect costs were related to human resources (overtime, sick leave), revenue shortfall, and security and psychiatric reinforcement. CONCLUSION: Indirect costs had a greater impact than did direct medical costs. Examining the level and variety of direct and indirect costs will lead to a better understanding of the consequences of terror acts and to improved preparation for future attacks.

Tenofovir alafenamide does not inhibit mitochondrial function and cholesterol biosynthesis in human T lymphoblastoid cell line.

In clinical trials, the concentration of tenofovir diphosphate (TFV-DP) in peripheral mononuclear cells was 4 to 5-fold higher in individuals treated with tenofovir alafenamide (TAF) compared to individuals treated with tenofovir disoproxil fumarate (TDF). We hypothesized that the higher intracellular accumulation of TFV-DP could cause mitochondrial toxicity from either polymerase gamma (Pol-γ)-dependent or Pol-γ-independent mechanism(s). To test this hypothesis, we cultured human T lymphoblastoid cell line (CEM cells) for up to 12 days with TAF or TDF (multiplicities of Cmax) to investigate the effects on mitochondrial function and respiration, and cholesterol biosynthesis. Both TAF and TDF treatments had no significant effect on cell growth, mitochondrial potential (ΔΨ), production of reactive oxygen species (ROS), and mitochondrial respiratory parameters. TAF had no statistically significant effect on expression of Pol-γ mRNA, mitochondria DNA (mtDNA) content, expression of proteins of the electron transport chain (ETC), and key genes of cholesterol biosynthesis. TDF had significant reduction in mtDNA content at 8xCmax, and statistically significant reduction in mRNA expression of squalene epoxidase (SQLE). Our findings do not support our hypothesis that the higher intracellular accumulation of TFV-DP in cells treated with TAF could cause mitochondrial dysfunction. In conclusion, our findings add to the emerging data that TAF may have a low potential for causing mitochondrial toxicity in HIV-infected individuals on TAF-containing regimens.

Conservative treatment of a pathologic fracture of the scaphoid bone in a child: A case report.

RATIONALE: Tumors of the scaphoid are rare, and some can cause pathological fractures. No cases of pathological fractures of the scaphoid have been reported in children. The most common treatment for pathologic fractures of the scaphoid bone associated with a benign lesion in adults is surgical, with intralesional curettage associated with autologous bone grafting and internal fixation. PATIENT CONCERNS: A 10-year-old boy presented with wrist pain after falling from his height. DIAGNOSES: X-ray, CT-scan and MRI showed a pathological undisplaced fracture of the scaphoid on a benign lytic lesion. INTERVENTIONS: The arm was immobilized in a below-elbow cast. OUTCOMES: The fracture healed within 4 months of immobilization. 3 years after the fracture, the functional status was normal, and the lytic lesion could not be seen on radiographs. LESSONS: Retrospectively, the most probable etiology was a ganglion cyst. Our case suggests that some pathological fractures of the scaphoid may not need surgery, especially not in children.

Why a P-Value is Not Enough.

BACKGROUND: All doctors know that P-value<0.05 is "the Graal," but publications require further parameters [odds ratios, confidence interval (CI), etc.] to better analyze scientific data. AIM: The aim of this study was to present P-values, CI, and common effect-sizes (Cohen d, odds ratio, and various coefficients) in a simple way. DESCRIPTION: The P-value is the probability, when the null hypothesis is true (eg, no difference or no association), of obtaining a result equal to or more extreme than what we actually observed. Simplistically, P-value quantifies the probability that the result is due to chance. It does not measure how big the association or the difference is. The CI on a value describes the probability that the true value is within a given range. A 95% CI means that the CI covers the true value in 95 of 100 performed studies. The test is significant if the CI does not include the null hypothesized difference or association (eg, 0 for difference). The effect-sizes are quantitative measures of the strength of a difference or association. If the P-value is <0.05 but the effect size is very low, the test is statistically significant but probably, clinically not so. CONCLUSIONS: Scientific publications require more parameters than a P-value. Statistical results should also include effect sizes and CIs to allow for a more complete, honest, and useful interpretation of scientific findings.

Validation of a Clinical Prediction Model for the Development of Neuromuscular Scoliosis: A Multinational Study.

BACKGROUND: The objective of this study was to evaluate the performance of a clinical prediction model of neuromuscular scoliosis via external validation. METHODS: We analyzed a series of 120 patients (mean age ± standard deviation, 15.7 ± 1.8 years; range: 12 to 18 years) with cerebral palsy, severe motor disorders, and cognitive impairment with and without neuromuscular scoliosis treated in two specialized units (70 patients from Nice, France, and 50 patients from Lublin, Poland) in a cross-sectional, double-blind study. Data on etiology, diagnosis, functional assessments, type of spasticity, epilepsy, scoliosis, and clinical history were collected prospectively between 2005 and 2015. Fisher's exact test and multiple logistic regressions were used to identify influential factors for developing spinal deformity. Thus, we applied a predictive model based on a logistic regression algorithm to predict the probability of scoliosis onset for new patients. RESULTS: Children with truncal tone disorders (P = Multivariate logistic regression highlighted previous hip surgery (P = 0.002 ≈ 0.005), intractable epilepsy (P = 0.01 ≈ 0.04) and female gender (0.07) as influent factors in the two cohorts. Average accuracy, sensitivity, and specificity of the predictive model were 74%. CONCLUSIONS: We validated a prediction model of neuromuscular scoliosis. In cerebral palsy subjects with the previouslymentioned predictors of scoliosis, the frequency of clinical examinations of spine and spinal x-ray should be increased to easily identify candidates for treatment.
