Sputum-Rheology-Based Strategy for Guiding Azithromycin Prescription in COPD Patients with Frequent Exacerbations: A Randomized, Controlled Study ("COPD CARhE").

(1) Background: We have previously shown that sputum rheology can discriminate between patients with COPD and other muco-obstructive lung diseases, and that it is correlated with mucin content and sputum eosinophilia. We now hypothesize that it could be a more-accurate guide than clinical evaluation for the prescription of azithromycin to prevent exacerbations of COPD and to reduce exposure to antibiotics; (2) Methods: "COPD CaRhe" is a multicentric, randomized, controlled trial comparing outcomes in two parallel arms (36 vs. 36 patients).

Application of an algorithm to analyze patterns of intermittent oral corticosteroid use in asthma.

An algorithm to describe patterns of intermittent oral corticosteroid use in the UK (n = 476,167) found that one-third of patients receiving intermittent oral corticosteroids for asthma only had short gaps (<90 days) between oral corticosteroid prescriptions sometime during follow-up. The increasing frequency pattern was more likely in patients with greater asthma severity and with more short-acting β-agonist use at baseline. Our approach may provide a clinically relevant representation of intermittent oral corticosteroid use in asthma.

Rheology predicts sputum eosinophilia in patients with muco-obstructive lung diseases.

Background: Mucus is known to play a pathogenic role in muco-obstructive lung diseases, but little is known about the determinants of mucus rheology. The purpose of this study is to determine which sputum components influence sputum rheology in patients with muco-obstructive lung diseases.

Methods: We performed a cross sectional prospective cohort study.

Characteristics and Long-term Outcomes of Pulmonary Venoocclusive Disease Induced by Mitomycin C.

Background: Pulmonary venoocclusive disease (PVOD) is an uncommon form of pulmonary hypertension (PH) predominantly characterized by pulmonary vein and capillary involvement. An association between chemotherapy, in particular mitomycin C (MMC), and PVOD has been reported.

Research Question: What are the characteristics of MMC-induced PVOD, and what is the prognosis for patients with MMC-induced PVOD?

Study Design And Methods: We report the clinical, functional, radiologic, and hemodynamic characteristics at diagnosis and outcomes of patients with PVOD from the French PH Registry after exposure to MMC.

International severe asthma registry (ISAR): protocol for a global registry.

Background: Severe asthma exerts a disproportionately heavy burden on patients and health care. Due to the heterogeneity of the severe asthma population, many patients need to be evaluated to understand the clinical features and outcomes of severe asthma in order to facilitate personalised and targeted care. The International Severe Asthma Registry (ISAR) is a multi-country registry project initiated to aid in this endeavour.

Evidence for and against vertical transmission for severe acute respiratory syndrome coronavirus 2.

COVID-19 can severely affect pregnant women Furthermore, issues regarding vertical transmission of severe acute respiratory syndrome coronavirus 2 are emerging. In patients and neonates who are showing symptoms of coronavirus disease 2019, real-time polymerase chain reaction of nasal and throat swabs, sputum, and feces is performed to detect the presence of severe acute respiratory syndrome coronavirus 2. In addition, real-time polymerase chain reaction of vaginal swabs, amniotic fluid, placenta, cord blood, neonatal blood, or breast milk for the detection of severe acute respiratory syndrome coronavirus 2 did not show substantial results.

Matching-adjusted comparison of oral corticosteroid reduction in asthma: Systematic review of biologics.

Background: Oral corticosteroid (OCS) treatment for severe asthma is associated with substantial disease burden. Thus, OCS dosage reduction is desirable. Relative efficacy of biologics in reducing OCS treatment for severe, uncontrolled asthma is not fully characterized.

Population Pharmacokinetics Modelling and Simulation of Mitotane in Patients with Adrenocortical Carcinoma: An Individualized Dose Regimen to Target All Patients at Three Months?

Mitotane is the most effective agent in post-operative treatment of adrenocortical carcinoma. In adults, the starting dose is 2-3 g/day and should be slightly increased to reach the therapeutic index of 14-20 mg/L. This study developed a population PK model for mitotane and to simulate recommended/high dosing regimens.

Matching-adjusted indirect comparison of benralizumab interleukin-5 inhibitors for the treatment of severe asthma: a systematic review.

Benralizumab is an interleukin-5 receptor α-directed cytolytic monoclonal antibody that directly depletes eosinophils. Its relative efficacy other IL-5-targeted treatments for patients with severe, uncontrolled asthma is not yet fully characterised.We performed a matching-adjusted indirect comparison (MAIC) of benralizumab mepolizumab and reslizumab.

Impact of psychological factors on the health-related quality of life of patients treated for pulmonary arterial hypertension.

Objective: Pulmonary arterial hypertension (PAH) is a rare and life-threatening disease well-marked by under diagnosis, delayed diagnosis and atypical treatments. Few data are available on the quality of life (QoL) and psychosocial characteristics of patients with PAH. Our aim is to describe the impact of psychological factors on the health-related quality of life (HRQoL) of treated PAH patients in a cross-sectional study.

Subsolid Lung Nodule Classification: A CT Criterion for Improving Interobserver Agreement.

Purpose To evaluate an objective computed tomographic (CT) criterion for distinguishing between part-solid (PS) and nonsolid (NS) lung nodules. Materials and Methods This study received institutional review board approval, and patients gave informed consent. Preoperative CT studies in all patients who underwent surgery for subsolid nodules between 2008 and 2015 were first reviewed by two senior radiologists, who subjectively classified the nodules as PS or NS.

Renal graft intolerance syndrome in late graft failure patients: efficacy and safety of embolization as first-line treatment compared to surgical removal.

Although renal graft percutaneous embolization was introduced to avoid the risk associated with graft nephrectomy, there is no universal consensus about its indications and results. In order to evaluate the efficacy of graft embolization in the treatment of graft intolerance syndrome as well as its safety compared to surgical removal with respect to complications and other morbidity measures, We performed a retrospective observational study comparing two groups of patients treated for graft intolerance syndrome: Group 1: patients who had embolization as first-line treatment and Group 2: patients directly treated by surgical removal. 72 patients were included, (32 in Group 1 and 40 in Group 2); the postintervention follow-up continued for 12 months.

Normal postoperative appearances of lung cancer.

The major lung resections are the pneumonectomies and lobectomies. The sublobar resections are segmentectomies and wedge resections. These are performed either through open surgery through a thoracotomy or by video-assisted mini-invasive surgery for lobectomies and sublobar resections.

Complications and follow up of subarachnoid hemorrhages.

Complications of subarachnoid hemorrhage are the major life threatening and functional components of the follow up of a ruptured aneurysm. Knowing how to identify these is a key challenge. They vary in type throughout the postoperative follow up period.

Utility of reassessment after neoadjuvant therapy and difficulties in interpretation.

We describe the main tools for MR assessment of the response of rectal cancer tumors after chemotherapy, before surgery. In locally advanced cases of rectal and lower rectal cancer, MR is useful in allowing the treatment strategy to be adjusted, enabling conservative surgery to be performed if the patient responds well. The different types of response (fibrous, desmoplastic and colloid), their appearances and difficulties in MR interpretation are described.

Correlation between MR imaging - prognosis factors and molecular classification of breast cancers.

The molecular classification of breast cancers defines subgroups of cancer with different prognoses and treatments. Each molecular type representing the intrinsic signature of the cancer corresponds to a histological profile incorporating hormone receptors, HER2 status and the proliferation index. This article describes the correlations between this molecular classification obtained in routine clinical practice using histological parameters and MRI.

Infectious chest complications in haematological malignancies.

The management of infections in haematology is dictated by the patient's type of acquired or induced immune deficiency (neutropenia, deficiency in cell-mediated or antibody-mediated immunity), and findings from clinical examination, laboratory studies, or morphologic investigations. The CT scan dominates in the initial management and follow-up of these patients, since clinical features very often appear to be non-specific. The radiologist's role is to guide the clinician towards a specific diagnosis such as aspergillosis or pneumocystosis, or to point them towards a non-infectious cause: tumour localisation, hypervolaemia, bronchiolitis obliterans suggestive of GVH disease, drug toxicity, or embolism.
