Electronic Medication Regimen Complexity Index at admission and complications during hospitalization in medical wards: a tool to improve quality of care?

OBJECTIVE: Adverse events during hospitalization are a major worry considering their frequency and their burden. Many could be avoided by immediate identification of at-risk patients at admission and adapted prevention. The complexity of a patient's medication regimen immediately available at admission is a good indicator of the complexity of the patient's condition. This study aims to determine whether the electronic Medication Regimen Complexity Index (MRCI) at admission is associated with complications during hospitalization. DESIGN: We performed a multilevel logistic regression model, adjusted for age and sex. SETTING: Premier Perspective™ database, a clinical and financial information system from 417 US hospitals. PARTICIPANTS: Adults hospitalized for more than 3 days in a medical ward and included in Premier's Perspective™ database for 2006. INTERVENTION(S): Multilevel logistic regression. MAIN OUTCOME MEASURE: Association of the MRCI and complications during hospitalization, defined as in-hospital death, hospital-acquired infection, pressure ulcers; and need for highly technical healthcare, identified as the secondary introduction of catecholamines. RESULTS: In total, 1 592 383 admissions were included. The median MRCI at admission was 13 [interquartile range: 9-19]. The higher the MRCI, the higher the adjusted odds ratio of the following: in-hospital mortality, hospital-acquired infections, pressure ulcers and the secondary introduction of catecholamines. CONCLUSIONS: Our results suggested that the MRCI at admission was correlated with patient complexity, independent of age. Considering that patients with complex conditions pose a heavier workload for staff, measuring MRCI at admission could be used to allocate resources in medical wards at an institutional level. The MRCI might be a useful tool to assess the management of care.

Is contrast enhanced ultrasonography a useful tool for the evaluation of muscular microcirculation in patients with critical limb ischaemia?

BACKGROUND: Evaluation of skin microcirculation in patients with critical limb ischemia (CLI) may be achieved by the measurement of transcutaneous oxygen pressure or skin perfusion pressure, but there is no practical method available for the evaluation of muscle microcirculation. Contrast enhanced ultrasonography (CEUS) has been used to assess muscle perfusion in patients with peripheral arterial disease. We conducted a monocentric pilot study evaluating the ability of CEUS to assess the impact of arterial revascularization on the perfusion of the calf muscle in patients with CLI. PATIENTS AND METHODS: Patients with CLI (TASC II criteria) and a possibility of proximal or medial revascularization were included. In addition to TcPO2 and toe systolic blood pressure measurements, CEUS of the calf muscle was performed just before and one month after the therapeutic procedure. Parameters derived from muscular perfusion curves were evaluated in a blinded fashion and compared with the clinical outcome. RESULTS: Thirty eight patients were included (74 % men, median age 71 years, 53 % diabetics). Thirty benefited from revascularization with a clinical success rate of 70 %. Twenty three patients could benefit from analysis before and after revascularization. No significant difference was shown in time to peak (22.3 s vs 24.0 s, P = 0.61) nor in peak intensity (2.30 dB vs 1.27 db, P = 0,26), contrasting with significant improvements of TcPO2 (43 mm Hg vs 20 mm Hg, P = 0.007) and toe systolic blood pressure (54 mm Hg vs 32 mm Hg, P = 0.002). CONCLUSIONS: The evaluation of muscular microvascular perfusion by CEUS as performed in this study is not enough sensitive to change to allow a clinically relevant evaluation of the improvement in muscle microvascular perfusion in patients with CLI benefiting from revascularization procedures.

Critical limb ischaemia and the response to bone marrow-derived cell therapy according to tcPO2 measurement.

BACKGROUND: Cell therapy is an emerging potential biotherapy for critical limb ischaemia (CLI) patients who are not eligible for revascularization. However, the findings on this technique's efficacy are inconsistent. Trials investigating this topic focused on the more severe CLI patients who were often beyond any therapy. Therefore, identifying those who may truly benefit from cell transplantation is now warranted. To this end, we studied the prognostic value of tcPO2 for major amputation after 1 year in patients treated with bone marrow-derived cells. PATIENTS AND METHODS: CLI patients ineligible for revascularization were included in a cell-therapy pilot study. On inclusion, patients underwent tcPO2 measurement in supine and sitting positions. For a tcPO2 < 10 mmHg in the supine position, the vascular reserve was defined by tcPO2 > 30 mmHg in the sitting position. Patients were administered intramuscular injections of mononuclear cells derived from aspirated bone marrow. RESULTS: In total, 25 patients (a lower limbs) were included for analysis. At inclusion, 11 lower limbs had tcPO2 at rest > 10 mmHg, and 16 lower limbs had a tcPO2 < 10 mmHg. The success probability for cell therapy was 0.79 (95 % CI 0.38-0.94) and 0.44 (95 % CI 0.18-0.67), respectively (p = 0.1). Of the 16 limbs with tcPO2 < 10 mmHg, the success rate was considerably higher in patients demonstrating a tcPO2 increase in a sitting position of over 30 mmHg (6/8, success probability 0.71, 95 % CI 0.26-0.92) compared to those without (2/8, success probability 0.15, 95 % CI 0.01-0.48, p = 0.03). CONCLUSIONS: For patients with chronic CLI for whom cellular therapy is a therapeutic option, a tcPO2 < 10 mmHg at rest, without vascular reserve (i. e. < 30 mmHg when sitting), is a prognostic indicator for poor outcome.

Active tuberculosis and venous thromboembolism: association according to international classification of diseases, ninth revision hospital discharge diagnosis codes.

BACKGROUND: Infections are risk factors for venous thromboembolism (VTE), especially if severe and acute. The role of chronic infections such as active tuberculosis is ill defined, although several case reports and small series have suggested an association between tuberculosis and VTE. METHODS: Using data from the Premier Perspective database (27 659 947 admissions), we performed a multivariate analysis to assess the specific VTE risk associated with tuberculosis. The analysis was adjusted on classic risk factors for VTE. RESULTS: The prevalence of VTE among patients with active tuberculosis was 2.07% (95% confidence interval [CI], 1.62%-2.59%). In a multivariate analysis model, adults with active tuberculosis had a greater risk of VTE than those without (odds ratio, 1.55 [95% CI, 1.23-1.97], P < .001), close to the previously reported risk associated with neoplasia. No particular link was found between pulmonary tuberculosis and pulmonary embolism, or between extrapulmonary tuberculosis and deep vein thrombosis. This may suggest the preponderant role of a systemic hypercoagulable state over an intrathoracic venous compression mechanism. In-hospital mortality of patients with both active tuberculosis and VTE (11/72 [15%]) was higher than mortality of patients with only active tuberculosis (92/3413 [2.7%]) or only VTE (5062/199 480 [2.5%]) (P < .001). Pulmonary embolism was more frequent in black patients, suggesting that this population, which is also more likely to suffer from tuberculosis, should be followed carefully. CONCLUSIONS: Tuberculosis must be considered as a pertinent risk factor for VTE and should be included in thromboembolism risk evaluation similar to any acute and severe infection.

A multicenter randomized controlled trial evaluating balneotherapy in patients with advanced chronic venous insufficiency.

BACKGROUND: Apart from compression therapy, physical therapy has scarcely been evaluated in the treatment of chronic venous disorders (CVDs). Spa treatment is a popular way to administer physical therapy for CVDs in France, but its efficacy has not yet been assessed in a large trial. The objective was to assess the efficacy of spa therapy for patients with advanced CVD (CEAP clinical classes C4-C5). METHODS: This was a single-blind (treatment concealed to the investigators) randomized, multicenter, controlled trial (French spa resorts). Inclusion criteria were primary or post-thrombotic CVD with skin changes but no active ulcer (C4a, C4b, or C5). The treated group had the usual 3-week spa treatment course soon after randomization; the control group had spa treatment after the 1-year comparison period. All patients continued their usual medical care including wearing compression stockings. Treatment consisted of four balneotherapy sessions per day for 6 days a week. Follow-up was performed at 6, 12 and 18 months by independent blinded investigators. The main outcome criterion was the incidence of leg ulcers at 12 months. Secondary criteria were a modified version of the Venous Clinical Severity Score, a visual analog scale for leg symptoms, and the Chronic Venous Insufficiency Questionnaire 2 and EuroQol 5D quality-of-life autoquestionnaires. RESULTS: Four hundred twenty-five subjects were enrolled: 214 in the treatment group (Spa) and 211 in the control group (Ctr); they were similar at baseline regarding their demographic characteristics, the severity of the CVD, and the outcome variables. At 1 year, the incidence of leg ulcers was not statistically different (Spa: +9.3%; 95% confidence interval [CI], +5.6 - +14.3; Ctr: +6.1%; 95% CI, +3.2 - +10.4), whereas the Venous Clinical Severity Score improved significantly in the treatment group (Spa: -1.2; 95% CI, -1.6 - -0.8; Ctr: -0.6; 95% CI, -1.0 - -0.2; P = .04). A significant difference favoring spa treatment was found regarding symptoms after 1 year (Spa: -0.03; 95% CI, -0.57 - +0.51; Ctr: +0.87; 95% CI,+0.46 - +1.26; P = .009). EuroQol 5D improved in the treatment group (Spa: +0.01; 95% CI, -0.02 - +0.04) while it worsened (Ctr: -0.07; 95% CI, -0.10 - -0.04) in the control group (P < .001). A similar pattern was found for the Chronic Venous Insufficiency Questionnaire 2 scale (Spa: -2.0; 95% CI, -4.4 - +0.4; Ctr: +2.4; 95% CI, +0.2 - +4.7; P = .008). The control patients showed similar improvements in clinical severity, symptoms, and quality of life after their own spa treatment (day 547). CONCLUSIONS: In this study, the incidence of leg ulcers was not reduced after a 3-week spa therapy course. Nevertheless, our study demonstrates that spa therapy provides a significant and substantial improvement in clinical status, symptoms, and quality of life of patients with advanced venous insufficiency for at least 1 year.

Impact of information leaflets on behavior of patients with gastroenteritis or tonsillitis: a cluster randomized trial in French primary care.

OBJECTIVE: To assess the impact of four patient information leaflets on patients' behavior in primary care. DESIGN: Cluster randomized multicenter controlled trial between November 2009 and January 2011. PARTICIPANTS: French adults and children consulting a participating primary care physician and diagnosed with gastroenteritis or tonsillitis. Patients were randomized to receive patient information leaflets or not, according to the cluster randomization of their primary care physician. INTERVENTION: Adult patients or adults accompanying a child diagnosed with gastroenteritis or tonsillitis were informed of the study. Physicians in the intervention group gave patients an information leaflet about their condition. Two weeks after the consultation patients (or their accompanying adult) answered a telephone questionnaire on their behavior and knowledge about the condition. MAIN MEASURES: The main and secondary outcomes, mean behavior and knowledge scores respectively, were calculated from the replies to this questionnaire. RESULTS: Twenty-four physicians included 400 patients. Twelve patients were lost to follow-up (3 %). In the group that received the patient information leaflet, patient behavior was closer to that recommended by the guidelines than in the control group (mean behavior score 4.9 versus 4.2, p < 0.01). Knowledge was better for adults receiving the leaflet than in the control group (mean knowledge score 4.2 versus 3.6, p < 0.01). There were fewer visits for the same symptoms by household members of patients given leaflets (23.4 % vs. 56.2 %, p < 0.01). CONCLUSION: Patient information leaflets given by the physician during the consultation significantly modify the patient's behavior and knowledge of the disease, compared with patients not receiving the leaflets, for the conditions studied.

Pupillometry to detect pain response during general anaesthesia following unilateral popliteal sciatic nerve block: a prospective, observational study.

CONTEXT: Pupillary reflex dilation appears to be a reliable indicator of response to noxious stimulation even under general anaesthesia. The ability of pupillometry to detect the effects of extremity blocks during continuous infusion of opioids remains unknown. OBJECTIVE: To explore the performance of pupillometry to detect differences in pupillary reflex dilation response to a standardised noxious stimulus applied to each leg following unilateral popliteal sciatic nerve block during continuous infusion of remifentanil. DESIGN: Prospective, observational study. SETTING: University hospital anaesthesia department, between June 2010 and December 2010. PATIENTS: Twenty-four adult patients undergoing elective foot or ankle surgery under general anaesthesia who requested a peripheral nerve block. Unilateral popliteal sciatic nerve block with 0.75% ropivacaine and 1% lidocaine was performed awake. General anaesthesia was maintained with steady-state infusions of propofol and remifentanil. MAIN OUTCOME MEASURE: Video-based pupillometer was used to determine pupillary reflex dilation during tetanic stimulation (60 m, 100 Hz) applied to the skin area innervated by the sciatic nerve for 5 s after the onset of general anaesthesia. RESULTS: Sensory nerve block led to a blunted maximal pupillary reflex dilation response to noxious stimulation compared with the non-blocked leg: median (interquartile range) change from baseline 2% (1 to 4%) versus 17% (13 to 24%), respectively (P < 0.01). The differences in the response persisted throughout the 5-s stimulus and the recovery phase. CONCLUSION: These results are a proof of concept. The effects of peripheral nerve block can be detected via the measurement of pupillary reflex dilation response to noxious stimulation of the skin in patients receiving remifentanil.

Corticosteroid after etomidate in critically ill patients: a randomized controlled trial.

OBJECTIVE: To investigate the effects of moderate-dose hydrocortisone on hemodynamic status in critically ill patients throughout the period of etomidate-related adrenal insufficiency. DESIGN: : Randomized, controlled, double-blind trial (NCT00862381). SETTING: University hospital emergency department and three intensive care units. INTERVENTIONS: After single-dose etomidate (H0) for facilitating endotracheal intubation, patients without septic shock were randomly allocated at H6 to receive a 42-hr continuous infusion of either hydrocortisone at 200 mg/day (HC group; n = 49) or saline serum (control group; n = 50). MEASUREMENTS AND MAIN RESULTS: After completion of a corticotrophin stimulation test, serum cortisol and 11ß-deoxycortisol concentrations were subsequently assayed at H6, H12, H24, and H48. Forty-eight patients were analyzed in the HC group and 49 patients in the control group. Before treatment, the diagnostic criteria for etomidate-related adrenal insufficiency were fulfilled in 41 of 45 (91%) and 38 of 45 (84%) patients in the HC and control groups, respectively. The proportion of patients with a cardiovascular Sequential Organ Failure Assessment score of 3 or 4 declined comparably over time in both HC and control groups: 65% vs. 67% at H6, 65% vs. 69% at H12, 44% vs. 54% at H24, and 34% vs. 45% at H48, respectively. Required doses of norepinephrine decreased at a significantly higher rate in the HC group compared with the control group in patients treated with norepinephrine at H6. No intergroup differences were found regarding the duration of mechanical ventilation, intensive care unit length of stay, or 28-day mortality. CONCLUSION: These findings suggest that critically ill patients without septic shock do not benefit from moderate-dose hydrocortisone administered to overcome etomidate-related adrenal insufficiency.

Antipsychotic drugs and risk of pulmonary embolism.

BACKGROUND: Antipsychotic drugs (APs) expose users to several adverse effects. Some reports describe an increased risk of venous thromboembolism for particular drugs in this family. PURPOSE: To examine the association between the risks of pulmonary embolism (PE) and AP use and assess any dose-effect relationships. METHODS: This is a retrospective analysis of data in 'Premier's Perspective' a large US hospital database for 2006. Adults in the AP group had at least one prescription of AP. Logistic regression analysis was performed to detect association between PE and AP use. The dose-effect relationship was assessed according to quantities and administration routes. Analyses were adjusted for potential confounders: age, sex, the components of the Charlson co-morbidity index, diagnoses of infection, sepsis, inflammatory bowel disease, psychotic disorders and hospital inpatient or outpatient status. RESULTS: Among 28,723,771 adults included in 2006, 450,951 (1.6%) were prescribed AP. Haloperidol was most commonly prescribed (157,667 patients or 35.0%), but atypical APs represented over 78% of prescriptions. The risk of PE was higher in AP users than in the total population (OR = 1.17 [95%CI 1.13-1.21]; p < 0.001) and depended on the type of AP used: clozapine was associated with the highest risk. Risk seemed correlated to higher doses. LIMITATIONS: Non-hospital prescription data were unavailable, potentially underestimating the number of patients exposed. The relative timing of AP prescription and PE was not available. Results did not include deep vein thrombosis. CONCLUSION: This study suggests an increased risk of PE with AP treatment, varying with type of AP and dependent on dose.

Information and Communication Technologies in Lung Transplantation: Perception of Patients and Medical Teams.

Optimal therapeutic management is a major determinant of patient prognosis and healthcare costs. Information and communication technologies (ICTs) represent an opportunity to enhance therapeutic management in complex chronic diseases, such as lung transplantation (LT). The objective of this study was to assess the preferences of LT patients and healthcare professionals regarding ICTs in LT therapeutic management. A cross-sectional opinion survey was conducted among lung transplant patients and healthcare professionals from the French lung transplantation centers. Five ICTs were defined (SMS, email, phone, internet, and smartphone application) in addition to face-to-face communication. An unsupervised approach by Principal Component Analysis (PCA) identified lung transplant patient profiles according to their preferences for ICTs. Fifty-three lung transplant patients and 15 healthcare professionals of the French LT centers were included. Both expected ICTs for treatment management and communication. Phone call, face-to-face, and emails were the most preferred communication tools for treatment changes and initiation. PCA identified four ICTs-related profiles ("no ICT", "email", "SMS", and "oral communication"). "Email" and "oral communication" profiles are mainly concerned with treatment changes and transmission of new prescriptions. The "SMS" profile expected reminders for healthcare appointments and optimizing therapeutic management. This study provides practical guidance to enhance LT therapeutic management by ICT intervention. The type of ICT used should take into account patient profiles to improve adherence and thereby the prognosis. A combination of strategies including information, education by a multidisciplinary team, and reminders is a promising approach to ensure an optimal management of our patients.

Comparison of the clinical history of symptomatic isolated muscular calf vein thrombosis versus deep calf vein thrombosis.

BACKGROUND: Half of all lower limb deep vein thromboses (DVT) are distal DVT that are equally distributed between muscular calf vein thromboses (MCVT) and deep calf vein thromboses (DCVT). Despite their high prevalence, MCVT and DCVT have never been compared so far, which prevents possible modulation of distal DVT management according to the kind of distal DVT (MCVT or DCVT). METHODS: Using data from the French, multicenter, prospective observational OPTimisation de l'Interrogatoire dans l'évaluation du risque throMbo-Embolique Veineux (OPTIMEV) study, we compared the clinical presentation and risk factors of 268 symptomatic isolated DCVT and 457 symptomatic isolated MCVT and the 3-month outcomes of the 222 DCVT and 390 MCVT that were followed-up. RESULTS: During the entire follow-up, 86.5% of DCVT patients and 76.7% of MCVT patients were treated with anticoagulant drugs (P = .003). MCVT was significantly more associated with localized pain than DCVT (30.4% vs 22.4%, P = .02) and less associated with swelling (47.9% vs 62.7%, P < .001). MCVT and DCVT patients exhibited the same risk factors profile, except that recent surgery was slightly more associated with DCVT (odds ratio, 1.70%; confidence interval, 1.06-2.75), and had equivalent comorbidities as evaluated by the Charlson index. At 3 months, no statistically significant difference was noted between MCVT and DCVT in death (3.8% vs 4.1%), venous thromboembolism recurrence (1.5% vs 1.4%), and major bleeding (0% vs 0.5%). CONCLUSION: Isolated symptomatic MCVT and DCVT exhibit different clinical symptoms at presentation but affect the same patient population. Under anticoagulant treatment and in the short-term, isolated distal DVT constitutes a homogeneous entity. Therapeutic trials are needed to determine a consensual mode of care of MCVT and DCVT.

Epidemiology and 3-year outcomes of combined oral contraceptive-associated distal deep vein thrombosis.

BACKGROUND: Distal deep vein thrombosis (infrapopliteal DVT without proximal DVT or pulmonary embolism [PE]) generally shares the same triggering risks factors as proximal DVT. In women of childbearing age, a frequent triggering risk factor is the use of combined oral contraceptive (COC) pills. However, data on the epidemiology and long-term outcomes of COC-associated distal DVT are lacking. OBJECTIVES: To assess the epidemiology and long-term outcomes of COC-associated distal DVT. METHODS: Using data from the OPTIMEV (Optimisation de l'Interrogatoire dans l'évaluation du risque thrombo-Embolique Veineux [Optimization of Interrogation in the Assessment of Thromboembolic Venous Risk]) multicenter cohort study of patients with objectively confirmed venous thromboembolism (VTE) enrolled between 2004 and 2006, we assessed in nonpregnant or postpartum women aged ≤ 50 years without cancer or history of VTE (i) proportion of COC-associated distal DVTs among women with distal DVTs and among women with COC-associated VTEs (distal DVT, proximal DVT, or PE) and (ii) 3-year incidence of death, bleeding, and VTE recurrence. RESULTS: COC-associated distal DVTs (n = 54) represented 43.9% of all distal DVTs and 51.9% of COC-associated VTEs. All but one woman with a COC-associated distal DVT received therapeutic anticoagulation for a median of 3 months. At 3-year follow-up, all women with COC-associated distal DVTs were alive, and none had bled during anticoagulant treatment or had experienced a DVT or PE recurrence after stopping anticoagulants. Similar results were found in patients with COC-associated proximal DVT and PE: The VTE recurrence rate was 1.7% per patient-year (PY) and 0% PY, respectively, and there were no deaths or major bleeds in either group. CONCLUSIONS: Distal DVT was the most frequent clinical presentation of COC-associated VTE and had similarly favorable long-term outcomes as other COC-associated VTE.

Comparative study on risk factors and early outcome of symptomatic distal versus proximal deep vein thrombosis: results from the OPTIMEV study.

There is a lack of consensus on the value of detecting and treating symptomatic isolated distal deep-vein thrombosis (DVT) of the lower limbs. In our study, we compared the risk factors and outcomes in patients with isolated symptomatic distal DVT with those with proximal symptomatic DVT. We analysed the data of patients with objectively confirmed symptomatic isolated DVT enrolled in the national (France), multicenter, prospective OPTIMEV study. This sub-study outcomes were recurrent venous thromboembolism, major bleeding and death at three months. Among the 6141 patients with suspicion of isolated DVT included between November 2004 and January 2006, DVT was confirmed in 1643 patients (26.8%). Isolated distal DVT was more frequent than proximal DVT (56.8% vs. 43.2%, respectively; p = 0.01). Isolated distal DVT was significantly more often associated with transient risk factors (recent surgery, recent plaster immobilisation, recent travel), whereas proximal DVT was significantly more associated with more chronic states (active cancer, congestive heart failure or respiratory insufficiency, age >75 years). Most patients (96.8%) with isolated distal DVT received anticoagulant therapies. There was no difference in the percentage of recurrent venous thromboembolism and major bleeding in patients with proximal DVT and isolated distal DVT. However, the mortality rate was significantly higher (p < 0.01) in patients with proximal DVT (8.0%) than in those with isolated distal DVT (4.4%). Symptomatic isolated distal DVT differs from symptomatic proximal DVT both in terms of risk factors and clinical outcome. Whether these differences should influence the clinical management of these two events remains to be determined.

Duration of adrenal inhibition following a single dose of etomidate in critically ill patients.

OBJECTIVE: To determine the incidence and duration of adrenal inhibition induced by a single dose of etomidate in critically ill patients. DESIGN: Prospective, observational cohort study. SETTING: Three intensive care units in a university hospital. PATIENTS: Forty critically ill patients without sepsis who received a single dose of etomidate for facilitating endotracheal intubation. MEASUREMENTS AND MAIN RESULTS: Serial serum cortisol and 11beta-deoxycortisol samples were taken at baseline and 60 min after corticotropin stimulation test (250 microg 1-24 ACTH) at 12, 24, 48, and 72 h after etomidate administration. Etomidate-related adrenal inhibition was defined by the combination of a rise in cortisol less than 250 nmol/l (9 microg/dl) after ACTH stimulation and an excessive accumulation of serum 11beta-deoxycortisol concentrations at baseline. At 12 h after etomidate administration, 32/40 (80%) patients fulfilled the diagnosis criteria for etomidate-related adrenal insufficiency. This incidence was significantly lower at 48 h (9%) and 72 h (7%). The cortisol to 11beta-deoxycortisol ratio (F/S ratio), reflecting the intensity of the 11beta-hydroxylase enzyme blockade, improved significantly over time. CONCLUSIONS: A single bolus infusion of etomidate resulted in wide adrenal inhibition in critically ill patients. However, this alteration was reversible by 48 h following the drug administration. The empirical use of steroid supplementation for 48 h following a single dose of etomidate in ICU patients without septic shock should thus be considered. Concomitant serum cortisol and 11beta-deoxycortisol dosages are needed to provide evidence for adrenal insufficiency induced by etomidate in critically ill patients.

Long-term outcomes of isolated superficial vein thrombosis in patients with active cancer.

BACKGROUND: Cancer patients who develop a deep-vein thrombosis (DVT) or a pulmonary embolism (PE) are at higher risk of death than similar cancer patients who do not develop DVT or PE. The impact of isolated superficial venous thrombosis (SVT) (i.e. without DVT or PE) on the prognosis of cancer patients is unknown. METHODS: Data from the OPTIMEV, multicentre, observational study, to compare at 3 years the incidences of death, DVT-PE recurrence and bleeding of cancer patients with objectively confirmed SVT vs. cancer patients with DVT (matched 1:2 on age, sex, cancer stage) and vs. patients with SVT without cancer (matched 1:3 on age and sex). RESULTS: Cancer patients with SVT (n = 34) had a high risk of death (23.2%patient-year(PY)), that was similar to that of cancer patients with DVT (aHR = 1.0[0.6-1.9]) and higher to that of SVT patients without cancer (aHR = 9.0[3.5-23.1]). Cancer patients with SVT received anticoagulants for a median duration of 45 days and had a high risk of DVT-PE recurrence (6.0%PY), similar to that of cancer patients with DVT (adjusted cause-specific HR (aCHR) = 1.5[0.4-5.8]) and higher to that of SVT patients without cancer (aCHR = 2.9[0.7-11.9]). In our population, venous thrombosis on varicose veins was associated with a lower risk of death (aHR = 0.6[0.3-1.0]) and DVT-PE recurrence (aCHR = 0.6[0.2-1.7]). CONCLUSION: Our results suggest that cancer patients with SVT have a poor prognosis, similar to that of patients with cancer-related DVT. The high rate of DVT-PE recurrence suggests that such patients may need longer duration of anticoagulant treatment.

Diagnosis Accuracy of Transcutaneous Bilirubinometry in Very Preterm Newborns.

BACKGROUND: Transcutaneous bilirubin (TcB) is a validated test for systematic screening of neonatal hyperbilirubinemia and monitoring term and near-term infants under phototherapy. OBJECTIVES: To evaluate TcB diagnostic accuracy for very preterm neonates. METHODS: Total serum bilirubin (TSB) and TcB measurements were performed prospectively in a multicenter sample of newborns <30 weeks of gestational age (GA). TcB sensitivity, specificity, predictive values, and likelihood ratios for the detection of neonates requiring phototherapy were calculated over the first 15 days of life, with or without phototherapy, with the expectation of achieving a detection rate of hyperbilirubinemia of over 95%. The potential influence of neonatal characteristics on the discordance between TcB and TSB in very preterm newborns was analyzed using multivariate multilevel logistic regression analyses. RESULTS: Altogether, 481 measurements were analyzed in 167 preterm patients. Mean GA was 27.6 ± 1.6 weeks. The rates of newborns requiring phototherapy were 52% in the first 3 days, 16% from the 4th to the 7th day, and 2% during the second week. Diagnostic performance was similar among babies with or without phototherapy. TcB sensitivity decreased over time from 100% (93.9-100.0) to 50% (1.3-98.7). Specificity showed an inverse evolution from 14.8% (7.0-26.2) to 80.7% (72.2-89.2). The best performance was that of negative predictive values which varied from 95.5 to 100.0. False negatives were rare throughout the study (0.8% of measurements). In a multivariate analysis, the only factor significantly influencing discordance between TcB and TSB was postnatal age. We did not find any impact of GA and skin color. CONCLUSION: Among very preterm babies, TcB measurements might be useful for screening for neonatal jaundice in the first 2 weeks of life. In case of a TcB value below the phototherapy threshold, invasive TSB quantification could be unnecessary, with potential avoidance of blood drawing.

RAGE and CYBA polymorphisms are associated with microalbuminuria and end-stage renal disease onset in a cohort of type 1 diabetes mellitus patients over a 20-year follow-up.

AIMS: We investigated the association of polymorphisms of three genes implicated in oxidative stress: CYBA C242T, RAGE -374T/A and -429T/C, and ALOX12 Arg261Gln, with the delay of microalbuminuria onset in patients with type 1 diabetes mellitus (DT1). METHODS: A total of 162 T1D patients presenting with diabetes for 32.9 ± 9 years were included in the study; 53 had persistent microalbuminuria (>30 mg/l) and 109 did not. Onset of diabetes, microalbuminuria and end-stage renal disease (ESRD) were recorded as bio-clinical data. We determined polymorphism association of microalbuminuria with a Cox regression model. RESULTS: All polymorphisms respected the Hardy-Weinberg equilibrium. The Cox regression model validated four significant variables associated with microalbuminuria: RAGE 374AA (HR 4.19 [1.84-9.58] (p = 0.001)), CYBA TT+TC (HR 2.1 [1.16-3.80], p = 0.015), male sex (HR 1.92 [1.07-3.43], p = 0.028) and diabetes diagnosis at the pediatric stage (HR 1.85 [1.03-3.32], p = 0.039). The same association was found with ESRD (p = 0.028 and p = 0.033 for CYBA TC+TT and RAGE 374AA, respectively). CYBA C242T and RAGE 374T/A were not significantly associated with diabetic retinopathy. CONCLUSIONS: CYBA C242T and RAGE -374T/A correlate with microalbuminuria onset in the French DT1 cohort. The same correlation with ESRD onset supports the argument for the involvement of a genetic predisposition involving kidney-specific oxidative stress for diabetic nephropathy.

Comparison of Immediate With Delayed Stenting Using the Minimalist Immediate Mechanical Intervention Approach in Acute ST-Segment-Elevation Myocardial Infarction: The MIMI Study.

BACKGROUND: Delayed stent implantation after restoration of normal epicardial flow by a minimalist immediate mechanical intervention aims to decrease the rate of distal embolization and impaired myocardial reperfusion after percutaneous coronary intervention. We sought to confirm whether a delayed stenting (DS) approach (24-48 hours) improves myocardial reperfusion, versus immediate stenting, in patients with acute ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention. METHODS AND RESULTS: In the prospective, randomized, open-label minimalist immediate mechanical intervention (MIMI) trial, patients (n=140) with ST-segment-elevation myocardial infarction ≤12 hours were randomized to immediate stenting (n=73) or DS (n=67) after Thrombolysis In Myocardial Infarction 3 flow restoration by thrombus aspiration. Patients in the DS group underwent a second coronary arteriography for stent implantation a median of 36 hours (interquartile range 29-46) after randomization. The primary end point was microvascular obstruction (% left ventricular mass) on cardiac magnetic resonance imaging performed 5 days (interquartile range 4-6) after the first procedure. There was a nonsignificant trend toward lower microvascular obstruction in the immediate stenting group compared with DS group (1.88% versus 3.96%; P=0.051), which became significant after adjustment for the area at risk (P=0.049). Median infarct weight, left ventricular ejection fraction, and infarct size did not differ between groups. No difference in 6-month outcomes was apparent for the rate of major cardiovascular and cerebral events. CONCLUSIONS: The present findings do not support a strategy of DS versus immediate stenting in patients with ST-segment-elevation infarction undergoing primary percutaneous coronary intervention and even suggested a deleterious effect of DS on microvascular obstruction size.

[The keys to success in French Medical National Ranking Examination: Integrated training activities in teaching hospital and medical school]. / Les clefs de la réussite à Grenoble aux Épreuves classantes nationales : les formations intégrées hospitalo-universitaire.

INTRODUCTION: The National Ranking Examination (NRE) is the key to the choice of career and specialty for future physicians; it lets them choose their place of employment in a specialty and an hospital for their internship. It seems interesting to model the success factors to this exam for the medical students from Grenoble University. METHODS: For each of the medical students at Grenoble University who did apply to the NRE in 2012, data have been collected about their academic background and personal details from the administration of the University. A simple logistic regression with success set as being ranked in the first 2000 students, then a polytomous logistic regression, have been performed. RESULTS: The 191 students in the models are 59% female, 25 years old in average (SD 1.8). The factors associated to a ranking in the first 2000 are: not repeating the PCEM1 class (odds ratio [OR] 2.63, CI95: [1.26; 5.56]), performing nurse practice during internships (OR=1.27 [1.00; 1.62]), being ranked in the first half of the class for S3 pole (OR=6.04 [1.21; 30.20] for the first quarter, OR=5.65 [1.15; 27.74] for the second quarter) and being in the first quarter at T5 pole (OR=3.42 [1.08; 10.82]). CONCLUSION: Our study finds four factors independently contributing to the success at NRE: not repeating PCEM1, performing nurse practice and being ranked in the top of the class at certain academic fields. The AUC is 0.76 and student accuracy is more than 80%. However, some items, for example repeating DCEM4 or participating in NRE mock exams, have no influence on success. A different motivation should be a part of the explanation… As these analysed data are mainly institutional, they are accurate and reliable. The polytomic logistic model, sharing 3 factors with the simple logistic model, replace a performing nurse practice factor's by a grant recipient factor.
