RESUMEN
INTRODUCTION: Mild traumatic brain injuries (mTBI) are common, but their outcomes are not very well known. A prospective study was conducted in Annecy hospital, France (CHRA), to assess the incidence of disorders 6 months after the injury and to identify risk factors for persistent disorders. METHOD: All patients admitted to the emergency department after a mild brain injury between February 2006 and July 2007 were included. They were contacted by telephone 6 months later to detect (by questionnaire) the presence of persistent disorders. Patients reporting disorders were referred to the l ocal brain injury centre for a follow-up check-up. RESULTS: Ninety three of the 795 patients contacted reported disorders: memory disorders (80%), sleep disorders (79%), headaches (65%), irritability (64%), speech disorders (64%) and concentration disorders (62%). Disorders at 6 months were independently associated with age, female gender, presence of headache at the initial examination and CT scan performed in the emergency department. DISCUSSION: The disorders reported in this study were consistent with the results of previous studies. As these disorders are usually nonspecific, a case-control study or an exposed-unexposed study would be necessary to determine whether or not these disorders are linked to mTBI.

OBJECTIVES: The diffusion of the SARS-CoV-2 Delta (B.1.617.2) variant and the waning of immune response after primary Covid-19 vaccination favoured the breakthrough SARS-CoV-2 infections in vaccinated subjects. To assess the impact of vaccination, we determined the severity of infection in hospitalised patients according to vaccine status. METHODS: We performed a retrospective observational study on patients hospitalised in 10 centres with a SARS-CoV-2 infection (Delta variant) from July to November 2021 by including all patients who had completed their primary vaccination at least 14 days before hospital admission and the same number of completely unvaccinated patients. We assessed the impact of vaccination and other risk factors through logistic regression. RESULTS: We included 955 patients (474 vaccinated and 481 unvaccinated). Vaccinated patients were significantly older (75.0 [63.25-84.0] vs. 55.0 [38.0-73.0]; p < 0.001), more frequently males (55.1% (261/474) vs. 46.4% (223/481); p = 0.009), and had more comorbidities (2.0 [1.0-3.0] vs. 1.0 [0.0-2.0]; p < 0.001). Vaccinated patients were less often admitted for Covid-19 (59.3% (281/474) vs. 75.1% (361/481); p < 0.001), had less extended lung lesions (≤25%: 64.3% (117/182) vs. 38.4% (88/229); p < 0.001), required oxygen less frequently (57.5% (229/398) vs. 73.0% (270/370); p < 0.001), at a lower flow (3.0 [0.0-8.7] vs. 6.0 [2.0-50.0] L/min, p < 0.001), and for a shorter duration (3 [0.0-8.0] vs. 6 [2.0-12.0] days, p < 0.001)., and required less frequently intensive care unit admission (16.2% (60/370) vs. 36.0% (133/369); p < 0.001) but had comparable mortality in bivariate analysis (16.7% (74/443) vs. 12.2% (53/433); p = 0.075). Multivariate logistic regression showed that vaccination significantly decreased the risk of death (0.38 [0.20-0.70](p = 0.002), ICU admission (0.31 [0.21-0.47](p < 0.001) and oxygen requirement (0.16 [0.10-0.26](p < 0.001), even among older patients or with comorbidities. CONCLUSIONS: Among patients hospitalised with a delta variant SARS-CoV-2 infection, vaccination was associated with less severe forms, even in the presence of comorbidities.

OBJECTIVES: Current guidelines recommend utilization of prehospital emergency medical services (EMSs) by patients with ST-elevation myocardial infarction (STEMI). The aims of this study were to estimate the percentage of inappropriate initial dispatcher decisions and determine their impact on delays in reperfusion therapy for EMS users with STEMI. METHODS: As part of a prospective regional registry of patients with STEMI, we analyzed the original data for 245 patients who called a university hospital-affiliated EMS call center in France. The primary study outcome was time to reperfusion therapy calculated from the documented date and time of the first patient call. RESULTS: The initial EMS dispatcher's decision was appropriate (ie, dispatching a mobile intensive care unit staffed by an emergency or critical care physician) for 171 (70%) patients and inappropriate for 74 (30%) patients. Inappropriate decisions included referring the patient to a family physician (n = 59), providing medical advice (n = 9), and dispatching an ambulance (n = 6). Inappropriate initial decisions resulted in increased median time to reperfusion for 140 patients receiving fibrinolysis (95 vs 53 minutes; P < .001) and 91 patients undergoing primary percutaneous coronary intervention (170 vs 107 minutes; P < .001). In-hospital mortality was not different between the 2 study groups (6.8% vs 9.9%; P = .42). CONCLUSION: The initial dispatcher's decision is inappropriate for 30% of EMS users with STEMI and results in substantial delays in time to reperfusion therapy. Accuracy of telephone triage should be improved for patients who activate EMSs in response to symptoms suggestive of acute coronary syndrome.

We examined oxidative stress markers of 31 patients suffering from ALS, 24 patients suffering from PD and 30 healthy subjects were included. We determined the plasma levels of lipid peroxidation (malondialdehyde, MDA), of protein oxidative lesions (plasma glutathione, carbonyls and thiols) and the activity of antioxidant enzymes i.e. erythrocyte Cu,Zn-Superoxide dismutase (SOD), Glutathione peroxidase (GSH-Px) and catalase. MDA and thiols were significantly different in both neurodegenerative diseases versus control population. A trend for an enhancement of oxidized glutathione was noted in ALS patients. Univariate analysis showed that SOD activity was significantly decreased in ALS and GSH-Px activity was decreased in PD. After adjusting for demographic parameters and enzyme cofactors, we could emphasize a compensatory increase of SOD activity in PD. Different antioxidant systems were not involved in the same way in ALS and PD, suggesting that oxidative stress may be a cause rather than a consequence of the neuronal death.

Evidence on the safety of complete compression ultrasound for ruling out deep venous thrombosis (DVT) is derived from studies conducted in tertiary care centers, although most patients with suspected DVT are managed in the ambulatory office setting. It was the objective of this study to estimate the rate of venous thromboembolism when anticoagulant therapy is withheld from ambulatory patients with normal findings on a single complete compression ultrasound. As part of a prospective cohort study, 3,871 ambulatory patients with clinically suspected DVT were enrolled by 255 board-certified vascular medicine physicians practicing in private offices in France. Compression ultrasound of the entire lower extremities was performed using a standardised examination protocol. Anticoagulant therapy was withheld from patients with negative findings on compression ultrasound, and 1,254 of them were randomly selected for follow-up. The main outcome measure was the three-month incidence of symptomatic venous thromboembolic events confirmed by objective testing. DVT was detected in 1,023 patients (26.4%), including 454 (11.7%) and 569 (14.7%) cases of proximal and isolated distal DVT, respectively. Of the 1,254 patients with negative results sampled for follow-up, six received anticoagulant therapy during follow-up and five were lost to follow-up. Five of 1,243 patients (0.4%, 95% confidence interval [CI], 0.1-0.9) experienced non-fatal symptomatic venous thromboembolic events (pulmonary embolism in two patients and DVT in three patients) and eight of 1,254 patients (0.6%, 95% CI, 0.3-1.2) died during the three-month follow-up. In conclusion, anticoagulant therapy can be safely withheld after negative complete compression ultrasound without further testing in the ambulatory office setting.

OBJECTIVE: To evaluate the functional, clinical, radiological and quality of life outcomes of a 4-week dynamic exercise programme (DEP) in RA. METHODS: Patients matched on the principal medico-social parameters were randomly assigned to either the DEP or the conventional joint rehabilitation group. Primary end point for judging effectiveness was functional status assessed by HAQ. Secondary outcomes included Nottingham Health Profile (NHP), Arthritis Impact Measurement Scale 2-Short Form (AIMS2-SF) and radiological worsening measured by Simple Narrowing Erosion Score (SENS). Clinical evaluation consisted of disease activity score (DAS 28), cycling aerobic fitness and dexterity. Dexterity was measured using Sequential Occupational Dexterity Assessment (SODA) and Duruoz Hand Index (DHI). Data were collected at baseline 1, 6 and 12 months. RESULTS: Fifty patients were enrolled. HAQ improved throughout the length of the trial in the DEP group. This improvement was greater in DEP than in the standard joint rehabilitation group at 1 month (-0.2 vs no variation from baseline, P = 0.04), but not at 6 months (-0.2 vs -0.1 in control group, P = 0.25) or 12 months (-0.1 vs no variation in control group, P = 0.51). DEP improved NHP (-23 vs + 7% in control group, P = 0.01) and aerobic fitness (+0.3 vs + 0.1 km per 5 min in control group, P = 0.02) at 1 month but the progress was not statistically significant thereafter. DEP also improved DHI, SODA, DAS 28 and AIMS2-SF, although not significantly. CONCLUSION: DEP was effective on functional status assessed by HAQ, quality of life and aerobic fitness at 1 month.

We introduce a new approach to hospital-acquired disease risk assessment from public health databases. In a spirit similar to actuarial risk theory, we define an adjustment coefficient that can quantify the risk associated with a hospital department, allowing comparisons of similar departments. The adjustment coefficient characterizes the tail of the distribution of the total patient length of stay in a department before the first disease event occurs. We show that this coefficient is the solution of a Lundberg-like equation, and we provide a nonparametric estimation procedure for this measure, based on a Cramér-Lundberg approximation for the tail of the distribution. Using simulations, we provide evidence of the robustness of the approximation to various individual risk models. In addition, we illustrate the relevance of this approach by evaluating the risk associated with a standard patient safety indicator in 20 hospitals of southeastern France.

OBJECTIVES: Quantitative evaluation of safety after the implementation of a computerized provider order entry (CPOE) system, stratification of residual risks to drive future developments. DESIGN: Comparative risk analysis of the drug prescription process before and after the implementation of CPOE system, according to the Failure Modes, Effects and Criticality Analysis (FMECA) method. MEASUREMENTS: The failure modes were defined and their criticality indices calculated on the basis of the likelihood of occurrence, potential severity for patients, and detection probability. Criticality indices of handwritten and electronic prescriptions were compared, the acceptability of residual risks was discussed. Further developments were proposed and their potential impact on the safety was estimated. RESULTS: The sum of criticality indices of 27 identified failure modes was 3813 for the handwritten prescription, 2930 (-23%) for CPOE system, and 1658 (-57%) with 14 enhancements. The major safety improvements were observed for errors due to ambiguous, incomplete or illegible orders (-245 points), wrong dose determination (-217) and interactions (-196). Implementation of targeted pop-ups to remind treatment adaptation (-189), vital signs (-140), and automatic edition of documents needed for the dispensation (-126) were the most promising proposed improvements. CONCLUSION: The impact of a CPOE system on patient safety strongly depends on the implemented functions and their ergonomics. The use of risk analysis helps to quantitatively evaluate the relationship between a system and patient safety and to build a strategy for continuous quality improvement, by selecting the most appropriate improvements to the system.

BACKGROUND: Ultrasonography is used routinely for ruling out suspected deep vein thrombosis in hospitalized patients, although most evidence supporting this strategy is derived from the outpatient setting. This study aimed to estimate the rate of venous thromboembolism when anticoagulant therapy was withheld from inpatients with normal findings on whole-leg ultrasonography. METHODS: As part of a prospective multicenter cohort study, 1926 medical and surgical inpatients with clinically suspected deep vein thrombosis during their stay were enrolled. Ultrasonography of all lower extremities was performed by board-certified vascular medicine physicians using a standardized examination protocol. Deep vein thrombosis was detected in 395 patients (20%). Anticoagulant therapy was withheld from patients with normal findings, and 523 of them were randomly selected for follow-up. The main outcome measure was 3-month incidence of symptomatic venous thromboembolism. RESULTS: A total of 513 patients with normal findings on ultrasonography successfully completed 3 months of follow-up, 9 patients were lost to follow-up, and 1 patient received anticoagulant therapy during follow-up. Three patients (0.6%) experienced nonfatal symptomatic venous thromboembolic events confirmed by objective testing. The cause of death was judged to be possibly related to pulmonary embolism for 7 other patients (1.3%). Overall, the 3-month rate of venous thromboembolism was 1.9% (10/513; 95% confidence interval, 0.9-3.5). CONCLUSION: Although withholding anticoagulant therapy after a single negative whole-leg ultrasonography seems to be safe, up to 3.5% of inpatients may nevertheless develop venous thromboembolism in the next 3 months. Further study is warranted to determine whether this strategy is equivalent to serial compression ultrasonography limited to proximal veins.

OBJECTIVE: To estimate the sensitivity of International Classification of Diseases, Tenth revision (ICD-10) hospital discharge diagnosis codes for identifying deep vein thrombosis (DVT) and pulmonary embolism (PE). STUDY DESIGN AND SETTING: We compared predefined ICD-10 discharge diagnosis codes with the diagnoses that were prospectively recorded for 1,375 patients with suspected DVT or PE who were enrolled at 25 hospitals in France. Sensitivity was calculated as the percentage of patients identified by predefined ICD-10 codes among positive cases of acute symptomatic DVT or PE confirmed by objective testing. RESULTS: The sensitivity of ICD-10 codes was 58.0% (159 of 274; 95% CI: 51.9, 64.1) for isolated DVT and 88.9% (297 of 334; 95% CI: 85.6, 92.2) for PE. Depending on the hospital, the median values for sensitivity were 57.7% for DVT (interquartile range, IQR, 48.6-66.7; intracluster correlation coefficient, 0.02; P=0.31) and 88.9% for PE (IQR, 83.3-96.3; intracluster correlation coefficient, 0.11; P=0.03). The sensitivity of ICD-10 codes was lower for surgical patients and for patients who developed PE or DVT while they were hospitalized. CONCLUSION: ICD-10 discharge diagnosis codes yield satisfactory sensitivity for identifying objectively confirmed PE. A substantial proportion of DVT cases are missed when using hospital discharge data for complication screening or research purposes.

A 68-year-old woman with a fragility fracture of the fourth lumbar vertebra was treated with a first vertebroplasty using methylmetacrylate with an initial good pain relief. Early painful recurrent vertebral fractures led to iterative vertebroplasties. Furthermore prophylactic treatment with methylmetacrylate of a non-fractured vertebra located between two previously injected ones did not prevent its collapse. This case report underlines the lack of a clear evaluation benefit/risk ratio of these procedures in patients with non-malignant bone fragility.
