[Approaching patient experience following pulmonary embolism: A systematic review]. / Approche de l'expérience du patient suite à une embolie pulmonaire : une revue systématique de la littérature.

INTRODUCTION: Pulmonary embolism (PE) is the major complication of thromboembolic disease. While a few qualitative studies have explored patient experience after PE, to our knowledge no literature review is available to date. The aim of this work was to explore patient experience after a PE episode through a systematic review of the literature comprising: patient experience, clinicians' perception of the patients' attitude and knowledge, and the patients' perception of VTE prevention strategies. METHODS: A search of PubMed, Web of science, Cochrane and EMBASE databases. The search was conducted without filters. Search results were combined and duplicates were removed. The selection was blinded by two independent researchers using the Rayyan application. RESULTS: Fifty studies were assessed for quality and 23 were included. Individual semi-structured interviews and focus groups were widely used to explore patient experience after a PE episode. Patients described deterioration in their quality of life, their psychological state and an initial feeling of carer abandonment. The trends observed appear to be more pronounced in patients with an episode characterized as unprovoked. CONCLUSION: These preliminary results call for further longitudinal studies, the objective being to better understand the evolution of these factors in the short and long terms.

Incidence and impact of anticoagulation-associated abnormal menstrual bleeding in women after venous thromboembolism.

Preliminary data and clinical experience have suggested an increased risk of abnormal uterine bleeding (AUB) in women of reproductive age treated with anticoagulants, but solid data are lacking. The TEAM-VTE study was an international multicenter prospective cohort study in women aged 18 to 50 years diagnosed with acute venous thromboembolism (VTE). Menstrual blood loss was measured by pictorial blood loss assessment charts at baseline for the last menstrual cycle before VTE diagnosis and prospectively for each cycle during 3 to 6 months of follow-up. AUB was defined as an increased score on the pictorial blood loss assessment chart (>100 or >150) or self-reported AUB. AUB-related quality of life (QoL) was assessed at baseline and the end of follow-up using the Menstrual Bleeding Questionnaire. The study was terminated early because of slow recruitment attributable to the COVID-19 pandemic. Of the 98 women, 65 (66%) met at least one of the 3 definitions of AUB during follow-up (95% confidence interval [CI], 57%-75%). AUB occurred in 60% of women (36 of 60) without AUB before VTE diagnosis (new-onset AUB; 95% CI, 47%-71%). Overall, QoL decreased over time, with a mean Menstrual Bleeding Questionnaire score increase of 5.1 points (95% CI, 2.2-7.9), but this decrease in QoL was observed only among women with new-onset AUB. To conclude, 2 of every 3 women who start anticoagulation for acute VTE experience AUB, with a considerable negative impact on QoL. These findings should be a call to action to increase awareness and provide evidence-based strategies to prevent and treat AUB in this setting. This was an academic study registered at www.clinicaltrials.gov as #NCT04748393; no funding was received.

[Patient expectations in asthma care]. / Attentes des patients asthmatiques vis-à-vis de leur prise en charge.

Asthma, a common chronic disease characterized by variable levels of severity, requires patient-centered management to achieve the best health outcomes. Studies have highlighted the gap between consensus management recommendations and patient goals, which represent a potential source of therapeutic wandering and of poor compliance. Patient expectations are continually evolving and are dependent on knowledge, feelings and individual experience. From this perspective, listening carefully to patients and caregivers makes it easier to exchange views and define common goals. The active participation of patients at all levels of decision-making and transmission of information may improve asthma control and other quality of life parameters.

[Diagnostic and therapeutic management of venous thromboembolic disease in obese patients]. / Prise en charge diagnostique et thérapeutique de la maladie veineuse thromboembolique chez le patient obèse.

Despite the high proportion of obese patients this population remains understudied in the field of venous thromboembolic disease (VTE). Obesity is a risk factor for pulmonary embolism and/or deep vein thrombosis, especially when it is associated with other risk factors for VTE. Currently there is no validated diagnostic algorithm for VTE in the population of obese patients. Moreover, imaging examinations can be of poor quality and inconclusive. In the prevention of VTE, data concerning obese patients are mainly based on low-level studies. Apart from the context of bariatric surgery, an adjustment of heparin doses according to the weight of the patient is proposed only on a case-by-case basis. According to the current guidelines, therapeutic fixed dose oral anticoagulants should not be prescribed for patients with weights exceeding 120kg or a body mass index>40kg/m2. Heparin doses should be weight adjusted and monitored with anti-Xa activity. Anti vitamin K can be prescribed but require INR monitoring. Therefore, new studies specifically dedicated to obese patients are required in the field of VTE for better diagnostic and therapeutic management.

[Azithromycine and chronic bronchial diseases: For which patients? For which benefits? With what modalities?] / Azithromycine et pathologies bronchiques chroniques : quels patients ? Quels bénéfices ? Quelles modalités ?

Azithromycin is a macrolide widely used in chronic bronchial diseases due to its anti-inflammatory properties. This treatment is prescribed to patients with bronchiectasis, asthma and severe chronic obstructive pulmonary disease who present more than 3 exacerbations per year or a deterioration of respiratory function despite an optimal treatment. Macrolides decrease the number of exacerbation but azythromycine must be prescribed carefully. Indeed, it involves potential cardiovascular and otological toxicities and the emergence of resistant bacteria. In addition, studies remain insufficient to establish the optimal dosage and duration of azithromycine.

[Risk factors for thromboembolic disease in young women-the role of hormones]. / Facteurs de risque de maladie veineuse thromboembolique chez les jeunes femmes en contexte hormonal: Risque de survenue d'une maladie thromboembolique veineuse chez les membres de la famille au 1er degré de femmes ayant une maladie veineuse thromboembolique en contexte hormonal : étude « FIT ­ H ¼.

Hormonal exposure in young women increases the risk of venous thromboembolic disease (VTE). Thrombophilia testing is often proposed in women of childbearing age before the initiation of contraception. However, the presence of a familial history of VTE has the potential to be more accurate than the presence of inherited thrombophilia. OBJECTIVE: To demonstrate an association between the risk of VTE in young women with hormonal exposure (pregnancy or oral contraceptive use) and the presence of a previous episode of VTE in their first-degree relatives, according to whether or not a detectable inherited thrombophilia was present. METHODS: We will perform a multicenter case-control cross-sectional study. The main risk factor is defined by the presence of a symptomatic VTE in young women with hormonal exposure. The principle variable is the presence of an objectively diagnosed episode of VTE in first-degree relatives. We will need to include 2,200 family members in 440 cases. EXPECTED RESULTS: We expect to improve understanding of the thrombotic risk in first-degree relatives of patients in hormonal context with or without a past history of VTE.

[A very unusual pleural presentation]. / Une pleurésie très inhabituelle.

Urinothorax refers to the presence of urine in the pleural space. Urinothorax is an infrequent and underdiagnosed pathology, with few cases reported, and these often suspected only with hindsight. It is usually a transudative pleural effusion. We report a case of urinothorax presenting as a purulent pleural effusion. Management of the urinothorax required antibiotics and surgical unblocking of the urinary tract. Currently, no test is available to confirm the diagnosis. The ratio of serum creatinine/pleural creatinine could suggest the presence of urinothorax but this parameter needs to be validated by complementary studies. Urinothorax should be suspected in the context of pleural effusion occurring after a recent urologic surgery.

Antipsychotic drugs and the risk of recurrent venous thromboembolism: A prospective cohort study.

BACKGROUND: Numerous studies have suggested that antipsychotic drugs are associated with an increased risk for a first episode of venous thromboembolism (VTE). However, after anticoagulation discontinuation, the impact of antipsychotic drugs on the risk of recurrent VTE (rVTE) remains unknown. OBJECTIVE: To estimate the risk of rVTE in association with antipsychotic drugs. METHODS: Between May 2000 and December 2012, we included all consecutive patients with a first unprovoked symptomatic VTE and who discontinued anticoagulation. During follow-up, exposure to antipsychotic drugs was systematically assessed. RESULTS: A total of 736 patients with a first unprovoked symptomatic VTE were followed-up during a median period of 27.0 months (interquartile range (IQR) 6.2-60.0). Patients' median age was 66.0 years (IQR 49.0-76.0), 404 (54.9%) were men, and 61 (8.3%) were exposed to antipsychotics during follow-up. The incidence rate of r VTE was 12.1% person-year (95% CI 7.2-20.5) in antipsychotics users compared with 8.3% person-year (95% CI 7.1-9.8) in non-users (p = 0.20). Multivariate analysis showed a significant increased risk of recurrence associated with antipsychotic exposure (adjusted hazard ratio 1.9, 95% CI 1.1-3.3). CONCLUSIONS: In this cohort study, exposure to antipsychotic drugs was found to be associated with an increased risk of rVTE among patients with a previous first unprovoked symptomatic VTE and who discontinued anticoagulation. Larger studies are needed to confirm and further explore this association.

The YEARS algorithm for suspected pulmonary embolism: shorter visit time and reduced costs at the emergency department.

Essentials The YEARS algorithm was designed to simplify the diagnostic workup of suspected pulmonary embolism. We compared emergency ward turnaround time of YEARS and the conventional algorithm. YEARS was associated with a significantly shorter emergency department visit time of ˜60 minutes. Treatment of pulmonary embolism was initiated 53 minutes earlier with the YEARS algorithm SUMMARY: Background Recently, the safety of the YEARS algorithm, designed to simplify the diagnostic work-up of pulmonary embolism (PE), was demonstrated. We hypothesize that by design, YEARS would be associated with a shorter diagnostic emergency department (ED) visit time due to simultaneous assessment of pre-test probability and D-dimer level and reduction in number of CT scans. Aim To investigate whether implementation of the YEARS diagnostic algorithm is associated with a shorter ED visit time compared with the conventional algorithm and to evaluate the associated cost savings. Methods We selected consecutive outpatients with suspected PE from our hospital included in the YEARS study and ADJUST-PE study. Different time-points of the diagnostic process were extracted from the to-the-minute accurate electronic patients' chart system of the ED. Further, the costs of the ED visits were estimated for both algorithms. Results All predefined diagnostic turnaround times were significantly shorter after implementation of YEARS: patients were discharged earlier from the ED; 54 min (95% CI, 37-70) for patients managed without computed tomography pulmonary angiography (CTPA) and 60 min (95% CI, 44-76) for the complete study population. Importantly, patients diagnosed with PE by CTPA received the first dose of anticoagulants 53 min (95% CI, 22-82) faster than those managed according to the conventional algorithm. Total costs were reduced by on average €123 per visit. Conclusion YEARS was shown to be associated with a shorter ED visit time compared with the conventional diagnostic algorithm, leading to faster start of treatment in the case of confirmed PE and savings on ED resources.

[Pulmonary granuloma in an immunodepressed patient]. / Un granulome pulmonaire chez une patiente immunodéprimée.

INTRODUCTION: Pulmonary alveolar echinococcosis is a rare but potentially severe condition. CASE REPORT: We report the case of a 50-year-old woman suffering from pulmonary alveolar echinococcosis who had had a renal transplant for polycystic liver and kidney disease. A lung opacity was identified radiologically in May 2013. Both broncho-alveolar lavage and bronchial biopsy were uninformative. In January 2014, a follow up CT-scan showed the opacity to be enlarging. A surgical biopsy revealed a giant cell epithelioid granuloma with caseous necrosis suggesting a diagnosis of pulmonary tuberculosis. Antituberculous treatment was started but cultures remained negative. A histological revue was therefore requested in March 2014. This suggested bronchocentric granulmatosis, possibly associated with echinococcosis. This hypothesis was finally confirmed serologically. Treatment for alveolar echinococcosis was begun in June 2014 after consultation with the national reference centre for parasitology. CONCLUSION: Outside endemic areas and in the absence of hepatic involvement pulmonary alveolar echinococcosis can be difficult to diagnose. This case report focuses on the diagnostic criteria and treatment.

Predicting the risk of cancer after unprovoked venous thromboembolism: external validation of the RIETE score.

Essentials Patients at high-risk of occult cancer may benefit from extensive screening. We validated the RIETE cancer score in the MVTEP study. One in three patients were classified as high-risk, 10% of whom had cancer diagnosed. The RIETE score identifies a subgroup at high risk for cancer. SUMMARY: Background Most recent trials evaluating extensive screening strategies for occult cancer in patients with unprovoked venous thromboembolism have failed, because, among other reasons, of an overall low rate of occult cancer. The RIETE investigators recently proposed a score aimed at identifying a subgroup at higher risk. Methods We retrospectively computed the RIETE score for all patients included in the MVTEP study, which evaluated the accuracy of [¹8F]fluorodeoxyglucose-positron emission tomography in the screening of occult cancer in patients with unprovoked venous thromboembolism. Performance of the RIETE score was assessed according to the proportion of patients classified in each risk group, and the corresponding rates of cancer diagnosis. Results Among the 386 patients included in the analysis, 136 patients (35.3%) were classified as high risk by the RIETE score. Cancer was diagnosed in 16 (11.8%) of them, whereas it was diagnosed in nine (3.6%) of the 250 patients with a low RIETE cancer score: odds ratio of 3.6 (95% confidence interval [CI] 1.53-8.32). The area under the receiver operating characteristic curve was 0.63 (95% CI 0.51-0.74). Conclusion The RIETE score seems to be able to identify a subgroup at high risk for cancer (10%) in our specific dataset of patients with unprovoked venous thromboembolism.

Use of clinical prediction rules and D-dimer tests in the diagnostic management of pregnant patients with suspected acute pulmonary embolism.

Because pregnant women have an increased risk of venous thromboembolism (VTE) and at the same time normal pregnancy is associated with symptoms, mimicking those present in the setting of acute pulmonary embolism (PE), the latter diagnosis is frequently suspected in this patient category. Since imaging tests expose both mother and foetus to ionizing radiation, the ability to rule out PE based on non-radiological diagnostic tests is of paramount importance. However, clinical decision rules have only been scarcely evaluated in the pregnant population with suspected PE, while D-dimer levels lose diagnostic accuracy due to a physiological increase during normal pregnancy. Consequently, clinical guidelines provide contradicting and weak recommendations on this subject and the optimal diagnostic strategy remains highly debated. With this systematic review, we aimed to summarize current evidence on the safety and efficacy of clinical decision rules and biomarkers used in the diagnostic management of suspected acute PE in pregnant patients.

[Cannabis "bong": A frequent, original and dangerous way of consumption]. / Le « bang ¼ de cannabis, un mode de consommation original, fréquent et dangereux.

The bong is a water pipe craft, used to smoke tobacco or cannabis. The benefit of consuming cannabis as a "bang" is based on the intensity and speed of the effect. The cannabis intoxication can then be associated with disorders of sensory functions, the type of distortion of perceptions or hallucinations, often accompanied by intense anxiety. Bong cannabis consumption appears to be responsible for specific side effects (especially hemoptysis), possibly related to the importance of inhalation of products of combustion of cannabis and combustion of plastic parts used in its manufacture.

Body mass index, a major confounder to insulin resistance association with unprovoked venous thromboembolism. Results from the EDITH case-control study.

Shared risk factors help explain the association between venous thromboembolism (VTE) and atherothrombosis. The potential association between insulin resistance and VTE has been poorly evaluated. Thus, we aimed to assess the association between insulin resistance and VTE in the EDITH hospital-based case-control study. Between May 2000 and December 2004, 677 patients with unprovoked VTE and their age- and sex-matched controls were included. Fasting glycaemia and insulinaemia were measured and insulin resistance was estimated with the homeostasis model assessment of insulin resistance (HOMA-IR) equation. The association between HOMA-IR and VTE was determined in non-diabetic patients in a quintile-based analysis. A total of 590 non-diabetic cases (median age 73.0 years, 255 men) and 581 non-diabetic controls (median age 72.0 years, 247 men) were analysed. There was a trend for a higher median level of HOMA-IR index in cases than in controls (1.21 [interquartile range 0.84-2.10] vs1.19 [interquartile range 0.72-2.02], p=0.08). The unadjusted analysis showed an increased risk of unprovoked VTE associated with increasing HOMA-IR (odds ratio [OR] 1.53; 95% confidence interval [CI] 1.00-2.34 for the highest quintile of HOMA-IR compared with the first quintile). Adjustment for lipid lowering drugs and antiplatelet agents use slightly modified the association (OR 1.51; 95% CI 0.97-2.34). When body mass index was added in the adjusted model, HOMA-IR was no longer associated with VTE (OR 1.08; 95% CI 0.67-1.73). Our results highlight the role of body mass index in the association between cardiovascular risk factors and VTE.

[Evaluation of preoperative non-invasive ventilation in thoracic surgery for lung cancer: the preOVNI study GFPC 12-01]. / Évaluation de la ventilation non invasive préopératoire avant chirurgie de résection pulmonaire. Étude préOVNI GFPC 12-01.

BACKGROUND: Surgical resection is the best treatment for stage I and II non-small cell lung cancer. Despite an improvement in the perioperative management of cancer patients and specialization of surgical teams, morbidity and mortality remains significant. Non-invasive ventilation (NIV) is an effective therapeutic option in hypercapnic respiratory failure. It also improves functional and gasometric parameters when undertaken before surgery. The objective of the preOVNI study is to demonstrate that preoperative non-invasive ventilation for 7 days, at home, reduces the postoperative respiratory and cardiovascular complications of lung resection surgery, in a high-risk population. METHODS: A prospective, randomized, controlled open-labelled multicentric French study, under the supervision of the Groupe Français de Pneumocancérologie (GFPC), comparing 7 days of preoperative non-invasive ventilation with standard treatment. Inclusion criteria are: patients suitable for lobectomy or segmentectomy for primary bronchial carcinoma and presenting with obstructive or restrictive lung disease, obesity or chronic cardiac insufficiency. The primary criterion is a composite one, including all respiratory and cardiac complications. The number of patients is 150 in each treatment arm, 300 in total. EXPECTED RESULTS: We think that preoperative NIV will be able to reduce the rate of postoperative complications. If this objective is achieved, the management of these patients could be changed.

[Pulmonary sarcomatoid carcinoma: Clinical and prognostic characteristics, a case report]. / Particularités cliniques et évolutives des carcinomes sarcomatoïdes du poumon: à propos d'un cas.

Sarcomatoid carcinoma is a rare malignancy in the family of non-small-cell lung cancer. They belong to a mixed group of poorly differenciated neoplasia, including sarcomatous cells or sarcomatoid-like cells with giant or spindle cells. We report the case of a 69-year-old man with sarcomatoid carcinoma. We describe the main characteristics of these tumors. Diagnosis is frequently delayed and lesions are locally advanced. The prognostic is poorer than other non-small-cell lung cancer. Chemotherapy is often not efficient.

[A case of a carcinoid tumour presenting as an "upper lobe syndrome"]. / Un cas de tumeur carcinoïde typique diagnostiqué sur un « syndrome du lobe supérieur ¼

A 53-year-old woman presented with progressive cough related to an endobronchial carcinoid tumour. The location of the tumour in the right upper lobe bronchus could be described as an "upper lobe syndrome" by analogy with the "middle lobe syndrome" or Brock's syndrome. Surgical management consisted of lobectomy and lymph node dissection. This established the diagnosis of typical carcinoid tumour. There was no mediastinal nodal invasion. Three months after surgery all symptoms had disappeared.
