Implementation of lung ultrasonography by general practitioners for lower respiratory tract infections: a feasibility study.

OBJECTIVE: To evaluate the feasibility of lung ultrasonography (LUS) performed by novice users' general practitioners (GPs) in diagnosing lower respiratory tract infections (LRTIs) in primary health care settings. DESIGN: A prospective interventional multicenter study (December 2019-March 2020). SETTINGS AND SUBJECTS: Patients aged >3 months, suspected of having LRTI consulting in three different general practices (GPs) (rural, semirural and urban) in France. MAIN OUTCOME MEASURES: Feasibility of LUS by GPs was assessed by (1) the proportion of patients where LUS was not performed, (2) technical breakdowns, (3) interpretability of images by GPs, (4) examination duration and (5) patient perception and acceptability. RESULTS: A total of 151 patients were recruited, and GPs performed LUS for 111 (73.5%) patients (LUS group). In 99.1% (n = 110) of cases, GPs indicated that they were able to interpret images. The median [IQR] exam duration was 4 [3-5] minutes. LRTI was diagnosed in 70.3% and 60% of patients in the LUS and no-LUS groups, respectively (p = .43). After LUS, GPs changed their diagnosis from 'other' to 'LRTI' in six cases (+5.4%, p < .001), prescribed antibiotics for five patients (+4.5%, p = .164) and complementary chest imaging for 10 patients (+9%, p < .001). Patient stress was reported in 1.8% of cases, 81.7% of patients declared that they better understood the diagnosis, and 82% of patients thought that the GP diagnosis was more reliable after LUS. CONCLUSIONS: LUS by GPs using handheld devices is a feasible diagnostic tool in primary health care for LRTI symptoms, demonstrating both effectiveness and positive patient reception.

Evaluation of Iodine Supplementation in Pregnant Women with Gestational Diabetes: IODIAB Study.

BACKGROUND: Iodine supplementation is indicated by the French National Authority for Health (HAS) and the World Health Organization (WHO) during pregnancy. This study investigates whether this supplementation is consistently prescribed in line with WHO recommendations in pregnant women diagnosed with gestational diabetes mellitus. METHOD: A total of 99 women with a diagnosis of gestational diabetes were included in the study and were all closely monitored. RESULTS: Only 17 (17.2%) patients received the recommended iodine supplementation. The follow-up, whether conducted by a gynecologist or midwife, did not influence the prescription of iodine supplements. By contrast, 72 (72.7%) of patients received folic acid supplementation. CONCLUSIONS: The prescription of iodine supplementation for the pregnant women included in our study is insufficient. Few practitioners seem aware of the recommendations, even when the pregnancy is complicated by gestational diabetes.

Treatment times, functional outcome, and hemorrhage rates after switching to tenecteplase for stroke thrombolysis: Insights from the TETRIS registry.

Introduction: The encouraging efficacy and safety data on intravenous thrombolysis with tenecteplase in ischemic stroke and its practical advantages motivated our centers to switch from alteplase to tenecteplase. We report its impact on treatment times and clinical outcomes. Methods: We retrospectively analyzed clinical and procedural data of patients treated with alteplase or tenecteplase in a comprehensive (CSC) and a primary stroke center (PSC), which transitioned respectively in 2019 and 2018. Tenecteplase enabled in-imaging thrombolysis in the CSC. The main outcomes were the imaging-to-thrombolysis and thrombolysis-to-puncture times. We assessed the association of tenecteplase with 3-month functional independence and parenchymal hemorrhage (PH) with multivariable logistic models. Results: We included 795 patients, 387 (48.7%) received alteplase and 408 (51.3%) tenecteplase. Both groups (tenecteplase vs alteplase) were similar in terms of age (75 vs 76 years), baseline NIHSS score (7 vs 7.5) and proportion of patients treated with mechanical thrombectomy (24.1% vs 27.5%). Tenecteplase patients had shorter imaging-to-thrombolysis times (27 vs 36 min, p < 0.0001) mainly driven by patients treated in the CSC (22 vs 38 min, p < 0.001). In the PSC, tenecteplase patients had shorter thrombolysis-to-puncture times (84 vs 95 min, p = 0.02), reflecting faster interhospital transfer for MT. 3-month functional independence rate was higher in the tenecteplase group (62.8% vs 53.4%, p < 0.01). In the multivariable analysis, tenecteplase was significantly associated with functional independence (ORa 1.68, 95% CI 1.15-2.48, p < 0.01), but not with PH (ORa 0.68, 95% CI 0.41-1.12, p = 0.13). Conclusion: Switch from alteplase to tenecteplase reduced process times and may improve functional outcome, with similar safety profile.

Post-healing follow-up study of patients in remission for diabetic foot ulcers Pied-REM study.

The rate of recurrence for diabetic foot ulcer (DFU) is 50% at 2 years Armstrong DG, 2017. International recommendations call for regular monitoring to prevent DFU recurrence. We aim to investigate the relation between post-healing follow-up and recurrence rates. The study will begin in November 2021 and end in April 2022; final study results are scheduled for December 2022. The purpose of the study is to evaluate the benefit of the multidisciplinary follow-up of healed DFU patients at the rate of two annual consultations and its impact on foot wound recurrence.

Impact of the Rapid Normalization of Chronic Hyperglycemia on the Receptor Activator of Nuclear Factor-Kappa B Ligand and the Osteoprotegerin System in Patients Living with Type 2 Diabetes: RANKL-GLYC Study.

The RANKL-GLYC study aims to explore the impact of the rapid correction of chronic hyperglycemia on the receptor activator of nuclear factor-kappa B ligand (RANKL) and its antagonist osteoprotegerin (OPG). RANKL and OPG are considered the main factors in the pathophysiology of Charcot neuroarthropathy, a devastating complication of the joints that remains poorly understood. The study began recruiting patients in September 2021 and ends in June 2022; the final study results are scheduled for January 2023.

Comparison of Biological Agent Monotherapy and Associations Including Disease-Modifying Antirheumatic Drugs for Rheumatoid Arthritis: Literature Review and Meta-Analysis of Randomized Trials.

OBJECTIVE: Update the available evidence comparing biologic disease-modifying antirheumatic drugs (bDMARDs) in combination with conventional synthetic disease-modifying antirheumatic drugs (CsDMARDs) to bDMARDs in monotherapy in patients with rheumatoid arthritis. METHODS: Research was limited to randomized controlled trials. Major outcome: ACR 20 response criteria at 24 weeks. SECONDARY OUTCOMES: clinical and radiographic criteria at week 24, 52 and 104. RESULTS: 23 trials (6358 patients), including seven bDMARDs and one other molecule: Anbainuo (anti-TNF-R). No study satisfied our search criteria for anakinra, certolizumab and infliximab. Compared to bDMARD monotherapy, combination therapy gives a better ACR 20 at 24 weeks (RR: 0.88 (0.84-0.94)) in fixed and random effect models, and this result is sustained at 52 and 104 weeks. The results were mostly similar for all other outcomes without increasing the risk of adverse effects. CONCLUSION: This meta-analysis confirms the superiority of combination therapy over monotherapy in rheumatoid arthritis, in accordance to the usual guidelines.

Functional Outcome, Recanalization, and Hemorrhage Rates After Large Vessel Occlusion Stroke Treated With Tenecteplase Before Thrombectomy.

BACKGROUND AND OBJECTIVES: To investigate in routine care the efficacy and safety of IV thrombolysis (IVT) with tenecteplase prior to mechanical thrombectomy (MT) in patients with large vessel occlusion acute ischemic strokes (LVO-AIS), either secondarily transferred after IVT or directly admitted to a comprehensive stroke center (CSC). METHODS: We retrospectively analyzed clinical and procedural data of patients treated with 0.25 mg/kg tenecteplase within 270 minutes of LVO-AIS who underwent brain angiography. The main outcome was 3-month functional independence (modified Rankin Scale score ≤2). Recanalization (revised Treatment in Cerebral Ischemia score 2b-3) was evaluated before (pre-MT) and after MT (final). RESULTS: We included 588 patients (median age 75 years [interquartile range (IQR) 61-84]; 315 women [54%]; median NIH Stroke Scale score 16 [IQR 10-20]), of whom 520 (88%) were secondarily transferred after IVT. Functional independence occurred in 47% (n = 269/570; 95% confidence interval [CI] 43.0-51.4) of patients. Pre-MT recanalization occurred in 120 patients (20.4%; 95% CI 17.2-23.9), at a similar rate across treatment paradigms (direct admission, n = 14/68 [20.6%]; secondary transfer, n = 106/520 [20.4%]; p > 0.99) despite a shorter median IVT to puncture time in directly admitted patients (38 [IQR 23-55] vs 86 [IQR 70-110] minutes; p < 0.001). Final recanalization was achieved in 492 patients (83.7%; 95%CI 80.4-86.6). Symptomatic intracerebral hemorrhage occurred in 2.5% of patients (n = 14/567; 95% CI 1.4-4.1). DISCUSSIONS: Tenecteplase before MT is safe, effective, and achieves a fast recanalization in everyday practice in patients secondarily transferred or directly admitted to a CSC, in line with published results. These findings should encourage its wider use in bridging therapy. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that tenecteplase within 270 minutes of LVO-AIS increases the probability of functional independence.

Rapid glycemic regulation in poorly controlled patients living with diabetes, a new associated factor in the pathophysiology of Charcot's acute neuroarthropathy.

OBJECTIVE: Aggressive antidiabetic therapy and rapid glycemic control are associated with diabetic neuropathy. Here we investigated if this is also the case for Charcot neuroarthropathy. RESEARCH DESIGN AND METHODS: HbA1c levels and other relevant data were extracted from medical databases of 44 cases of acute Charcot neuroarthropathy. RESULTS: HbA1c levels significantly declined from 8.25% (67mmol/mol) [7.1%-9.4%](54-79mmol/mol), at -6 months (M-6), to 7.40%(54mmol/mol) [6.70%-8.03%] (50-64 mmol/mol) during the six months preceding the diagnosis of Charcot neuroarthropathy (P <0.001). CONCLUSIONS: HbA1c levels significantly declined during the six months preceding the onset of Charcot neuroarthropathy. This decline seems to be a associated factor with the appearance of an active phase of Charcot neuroarthropathy in poorly controlled patients with diabetic sensitive neuropathy.

Multifocal (tarsus and knee) activation of neuroarthropathy following rapid glycaemic correction.

OBJECTIVE: To report a case of neuroarthropathy in the tarsus and knee following rapid glycaemic normalisation in a female patient with type I diabetes. METHODS: A retrospective review of case notes. RESULTS: We describe the case of a female patient with type I diabetes who had developed a multifocal neuroarthropathy in only six months, probably due to a rapid glycaemic normalisation. The onset of this neuroarthropathy was not only fast but mostly multifocal affecting two levels of joints. CONCLUSION: The link between the onset of multifocal neuroarthropathy and the rapid correction of chronic hyperglycaemia is probably proven in our case. Patients with chronic hyperglycaemia with sensitive neuropathy should benefit from a gradual correction of their glycaemic imbalance in order to avoid the apparition of neuroarthropathy.

Decision to deploy coronary reperfusion is not affected by the volume of ST-segment elevation myocardial infarction patients managed by prehospital emergency medical teams.

OBJECTIVE: Mortality in patients with ST-segment elevation myocardial infarction (STEMI) has been associated with the volume of activity of percutaneous coronary intervention (PCI) facilities. This observational study investigated whether the coronary reperfusion-decision rate is associated with the volume of activity in a prehospital emergency setting. METHODS: Prospectively collected data for the period 2003-2013 were extracted from a regional registry of all STEMI patients handled by eight dispatch centers (SAMUs) in and around Paris [41 mobile ICU (MICUs)]. A possible association between volume of activity (number of STEMIs) and coronary reperfusion-decision rate, and subsidiarily between volume of activity and choice of technique (fibrinolysis vs. primary PCI), were investigated. Explanatory factors (patient age, sex, delay between pain onset and first medical contact, and access to a PCI facility) were analyzed in a multivariate analysis. RESULTS: Overall, 18 162 patients; male/female 3.5/1; median age 62 (52-72) years were included in the analysis. The median number of STEMIs per MICU was 339 (IQ 220-508) and that of reperfusion-decisions was 94% (91-95). There was no association between the decision rate and the number of STEMIs (P = 0.1). However, the decision rate was associated with age, sex, delay, and access to a PCI facility (P < 0.0001) in a highly significant way. Fibrinolysis was a more frequent option for low-volume (remoter PCI facilities) than high-volume MICUs (30 vs. 16%). CONCLUSION: The decision of coronary reperfusion in a prehospital emergency setting depended on patient characteristics, delay between pain onset and first medical contact, and access to a PCI facility, but not on volume of activity. Promoting fibrinolysis use in underserved areas might help increase the reperfusion-decision rate.

Pattern of improvement in upper limb pointing task kinematics after a 3-month training program with robotic assistance in stroke.

BACKGROUND: When exploring changes in upper limb kinematics and motor impairment associated with motor recovery in subacute post stroke during intensive therapies involving robot-assisted training, it is not known whether trained joints improve before non-trained joints and whether target reaching capacity improves before movement accuracy. METHODS: Twenty-two subacute stroke patients (mean delay post-stroke at program onset 63 ± 29 days, M2) underwent 50 ± 17 (mean ± SD) 45-min sessions of robot-assisted (InMotion™) shoulder/elbow training over 3 months, in addition to conventional occupational therapy. Monthly evaluations (M2 to M5) included Fugl-Meyer Assessment (FM), with subscores per joint, and four robot-based kinematic measures: mean target distance covered, mean velocity, direction accuracy (inverse of root mean square error from straight line) and movement smoothness (inverse of mean number of zero-crossings in the velocity profile). We assessed delays to reach statistically significant improvement for each outcome measure. RESULTS: At M5, all clinical and kinematic parameters had markedly improved: Fugl-Meyer, +65% (median); distance covered, +87%; mean velocity, +101%; accuracy, +134%; and smoothness, +96%. Delays to reach statistical significance were M3 for the shoulder/elbow Fugl-Meyer subscore (+43%), M4 for the hand (+80%) and M5 for the wrist (+133%) subscores. For kinematic parameters, delays to significant improvements were M3 for distance (+68%), velocity (+65%) and smoothness (+50%), and M5 for accuracy (+134%). CONCLUSIONS: An intensive rehabilitation program combining robot-assisted shoulder/elbow training and conventional occupational therapy was associated with improvement in shoulder and elbow movements first, which suggests focal behavior-related brain plasticity. Findings also suggested that recovery of movement quantity related parameters (range of motion, velocity and smoothness) might precede that of movement quality (accuracy). TRIAL REGISTRATION: EudraCT 2016-005121-36 . Date of Registration: 2016-12-20. Date of enrolment of the first participant to the trial: 2009-11-24 (retrospective data).

Identifying Patients at Risk for Prehospital Sudden Cardiac Arrest at the Early Phase of Myocardial Infarction: The e-MUST Study (Evaluation en Médecine d'Urgence des Stratégies Thérapeutiques des infarctus du myocarde).

BACKGROUND: In-hospital mortality of ST-segment-elevation myocardial infarction (STEMI) has decreased drastically. In contrast, prehospital mortality from sudden cardiac arrest (SCA) remains high and difficult to reduce. Identification of the patients with STEMI at higher risk for prehospital SCA could facilitate rapid triage and intervention in the field. METHODS: Using a prospective, population-based study evaluating all patients with STEMI managed by emergency medical services in the greater Paris area (11.7 million inhabitants) between 2006 and 2010, we identified characteristics associated with an increased risk of prehospital SCA and used these variables to build an SCA prediction score, which we validated internally and externally. RESULTS: In the overall STEMI population (n=8112; median age, 60 years; 78% male), SCA occurred in 452 patients (5.6%). In multivariate analysis, younger age, absence of obesity, absence of diabetes mellitus, shortness of breath, and a short delay between pain onset and call to emergency medical services were the main predictors of SCA. A score built from these variables predicted SCA, with the risk increasing 2-fold in patients with a score between 10 and 19, 4-fold in those with a score between 20 and 29, and >18-fold in patients with a score ≥30 compared with those with scores <10. The SCA rate was 28.9% in patients with a score ≥30 compared with 1.6% in patients with a score ≤9 (P for trend <0.001). The area under the curve values were 0.7033 in the internal validation sample and 0.6031 in the external validation sample. Sensitivity and specificity varied between 96.9% and 10.5% for scores ≥10 and between 18.0% and 97.6% for scores ≥30, with scores between 20 and 29 achieving the best sensitivity and specificity (65.4% and 62.6%, respectively). CONCLUSIONS: At the early phase of STEMI, the risk of prehospital SCA can be determined through a simple score of 5 routinely assessed predictors. This score might help optimize the dispatching and management of patients with STEMI by emergency medical services.

Preparing Drugs for Infusion Via Syringe Pump: A Key Step to Ensure Homogeneous Concentration.

OBJECTIVE: Preparation of drug solutions used with electronic syringe infusion pumps plays a crucial role in the delivery of an accurate drug concentration. Is there a correlation between drug concentrations during syringe pump infusion and preparation protocols? METHOD: Norepinephrine, insulin, and sufentanil were prepared in 3 different ways: (1) the drug was taken from the vial, then the solvent was added followed by an air bubble, and mixing was performed by turning the syringe top-to-bottom in a 180° shaking movement 5 consecutive times; (2) the drug was taken from the vial, then the solvent was added and not mixed; and (3) the solvent was taken from a stock solution, then the drug was added and not mixed. Concentrations of drugs were determined at different times during administration by reverse-phase high-performance liquid chromatography with ultraviolet detection. All analyses were performed in triplicate and were based on measurement of peak areas. RESULTS: With no shaking of the syringe, the concentration of the injected drugs varies widely. In any case, mixing of the syringe contents by turning the syringe in a top-to-bottom 180° shaking movement 5 times with an air bubble would ensure administration of the drug at a constant concentration. CONCLUSIONS: Without mixing, the concentrations of all drug solutions varied widely when administered via an electronic syringe infusion pump. Mixing syringe contents should be made part of the compulsory curriculum for administering medications at all levels of medical education. (Critical Care Nurse. 2016;36[4]:36-45).

Longer pre-hospital delays and higher mortality in women with STEMI: the e-MUST Registry.

AIMS: The mortality rate in patients with STEMI is higher in women than in men. This higher mortality rate is partly accounted for by certain known characteristics inherent in the female population (age, diabetes). Using data from the e-MUST registry on STEMI patients in the Greater Paris area, we assessed the differences between men and women treated with reperfusion strategies. METHODS AND RESULTS: Patients presenting within 24 hours of pain onset between 2006 and 2010 were included in the study. The male and female subpopulations were compared according to their baseline characteristics, their management delays and their early outcomes. Five thousand eight hundred and forty males (78.9%) and 1,557 females (21.1%) were included in the study. In-hospital mortality was significantly higher in women than in men, 143 (9.4%) vs. 254 (4.4%), p<0.0001, with a longer time to treatment initiation, symptoms to call (2.7±3.6 vs. 2.2±3.4 hours, p<0.0001), symptoms to first medical contact (FMC) (3.1±3.7 vs. 2.6±3.4 hours, p<0.0001), and call to FMC (25.6±23.5 vs. 23.6±18.3 min, p=0.02). After adjustment for clinical factors, severity criteria, myocardial infarction (MI) location and delays, mortality remained higher in women than in men with an odds ratio of 1.40 [1.06-1.84], p=0.017. CONCLUSIONS: We demonstrated longer pre-hospital delays and higher in-hospital mortality in women. The increase in the time to treatment alone does not completely explain the persistent increase in mortality. Further studies, public awareness programmes and physician education are necessary to reduce delays and improve the prognosis of STEMI in women.

[Evolution since 2002 of the management of patients with ST elevated acute coronary syndrome (STEMI) in Île-de-France. E-MUST survey]. / Augmentation du taux de décision de reperfusion myocardique des patients ayant un syndrome coronaire aigu avec sus-décalage du segment ST. Analyse du registre e-MUST (2002 à 2010) des SAMU/SMUR d'Île-de-France.

INTRODUCTION: ST-segment-elevation acute myocardial infarction (STEMI) is a therapeutic emergency. Early reperfusion is the key to successful reperfusion. Guidelines recommend organizing regional networks. In France, this starts with a call to a medical dispatch center, the SAMU-centre 15. The aim of this study was to evaluate regional STEMI management using data collected from 2002 to 2010. METHODS: Observational, prospective, multicenter survey. STEMI patient with chest pain lasting for less than 24hours managed by 40 mobile emergency and resuscitation service (SMUR) and 8 emergency medical system (SAMU) from the Greater Paris Area (Île-de-France) were analyzed. Demographic data, cardiovascular risk factors, infarction location, decision of reperfusion and delays were collected. The rate of coronary reperfusion was chosen as the primary endpoint. RESULTS: Eleven thousand five hundred and eighty-eight patients enrolled from 2002 to 2010 were analyzed. Median age was 59.9 (51.0 to 72.9) years; 9080 (78.5%) were men. The number of patients included decreased from 1376 in 2002 to 1119 in 2010. Reperfusion was achieved by fibrinolysis in 2644 (23%) cases and primary angioplasty in 7999 (69%) cases. The rate of decision of coronary reperfusion significantly increased from 86.7% in 2002 to 94.8% in 2010 (P<0.0001). Interaction between the increasing decision of reperfusion and all factors studied (demographics, cardiovascular risk factors, infarct location and delays) was significant only for family history of coronary artery disease (P=0.03). In-hospital mortality was 2.8% (321 cases). CONCLUSION: The number of patients with STEMI managed by the SAMU declined slightly over the past decade. The rate of decision of reperfusion progressively increased up to 95%. Entrance into the network by the SAMU-centre 15 is a guarantee of a wide and early access to the coronary reperfusion.

Outcomes of primary percutaneous coronary interventions in nonagenarians with acute myocardial infarction.

BACKGROUND: Few data are available on primary percutaneous coronary intervention (pPCI) in nonagenarians. In a large prospective registry on pPCI for STEMI we compared the demographics, procedural and in-hospital outcomes between nonagenarians (age ≥ 90 years) and patients aged < 90 years. METHODS AND RESULTS: We included 26,157 consecutive patients with pPCI in the Greater Paris Area region between 2003 and 2011. Of these, 418 (1.6%) were ≥ 90 years old. Nonagenarians (versus patients < 90 years) were more likely to be female (62.3% versus 22.5%, p < 0.0001), nonsmokers (81.6% versus 36.7%, p < 0.0001), in cardiogenic shock (Killip IV) upon admission (10.5% versus 4.8%, p < 0.001), and had significant co-morbidities. Over two-thirds of patients underwent procedures via the radial artery (61% versus 72.1%, p = 0.007). Both groups had high and similar angiographic success rates (98.1% versus 98.7%, p = 0.33). Drug-eluting stents were used less often in nonagenarians (4.4% versus 16.7%, p < 0.0001). Hospital mortality was significantly much higher in patients over 90 years old (24.9% versus 5.1%, p < 0.001) in univariate analysis. After adjustment for sex, cardiogenic shock, diabetes, triple vessel disease, drug-eluting stent use and glycoprotein IIb/IIIa inhibitors use, mortality remains higher in nonagenarian patients (OR: 4.31; 95% CI: 3.26-5.71, p < 0.0001). CONCLUSIONS: In a real-world setting, we found important demographic differences in nonagenarian compared to younger patients. Despite achieving a high rate of reperfusion with pPCI using mainly radial access, similar to that achieved in younger patients, hospital mortality was higher in nonagenarians.
