Treatment of two or more metatarsal fractures.

Introduction: Metatarsal fractures are the most common type of foot fracture. When surgical treatment is needed, pinning is typically used, either percutaneous or open. However, this fixation method has been criticized by some authors who lament residual malunion and prefer to use plate and/or screws.

Does early disease progression predict survival after first line-treatment of Waldenström macroglobulinemia?

In symptomatic Waldenström macroglobulinemia (sWM) patients, prognosis is assessed with the international prognostic scoring system (IPSSWM). In follicular lymphoma and other B-cell and T-cell lymphomas, disease progression within 24 months (POD24) or (in patients without POD24) after 24 months has been proposed as the start date for stratifying subsequent survival. In the present report, we assessed in a large series of 472 sWM patients, the prognostic value of this new dynamic endpoint already reported in many other lymphomas subtypes.

Impact of targeted hypothermia in expanded-criteria organ donors on recipient kidney-graft function: study protocol for a multicentre randomised controlled trial (HYPOREME).

Introduction: Expanded-criteria donors (ECDs) are used to reduce the shortage of kidneys for transplantation. However, kidneys from ECDs are associated with an increased risk of delayed graft function (DGF), a risk factor for allograft loss and mortality. HYPOREME will be a multicentre randomised controlled trial (RCT) comparing targeted hypothermia to normothermia in ECDs, in a country where the use of machine perfusion for organ storage is the standard of care.

Use of a Smartphone Self-assessment App for a Tobacco-Induced Disease (COPD, Cardiovascular Diseases, Cancer) Screening Strategy and to Encourage Smoking Cessation: Observational Study.

Background: Patient self-assessment via a mobile app detects actionable symptoms and has been shown to detect lung cancer relapses early, thereby lengthening survival.

Objective: The purpose of this study was to assess the incidence of chief symptoms associated with the main tobacco-induced pathologies in both current and ex-smokers through a self-assessment smartphone app and to evaluate the app's capacity to encourage users to quit smoking or reduce consumption, as well as its impact on early lung cancer stages at the time of diagnosis.

Methods: Current and ex-smokers were recruited through an advertising campaign in Sarthe county (France) proposing the free download of a smartphone app.

Factors associated with acute mesenteric ischemia among critically ill ventilated patients with shock: a post hoc analysis of the NUTRIREA2 trial.

Purpose: Acute mesenteric ischemia (AMI) is a rare, but life-threatening condition occurring among critically ill patients. Several factors have been associated with AMI, but the causal link is debated, most studies being retrospective. Among these factors, enteral nutrition (EN) could be associated with AMI, in particular among patients with shock.

Combination of Trastuzumab, Pertuzumab, and Docetaxel in Patients With Advanced Non-Small-Cell Lung Cancer Harboring Mutations: Results From the IFCT-1703 R2D2 Trial.

Purpose: exon 20 insertions and point mutations are oncogenic drivers found in 1%-2% of patients with non-small-cell lung cancer (NSCLC). No targeted therapy is approved for this subset of patients. We prospectively evaluated the effectiveness of the combination of two antibodies against human epidermal growth factor 2 (HER2 [HER2] trastuzumab and pertuzumab with docetaxel; trastuzumab and pertuzumab) and docetaxel.

Recurrence of Anti-Semaphorin 3B-Mediated Membranous Nephropathy after Kidney Transplantation.

Background: Membranous nephropathy (MN) is rare in pediatric patients, although its diagnosis may be underestimated in children who are responsive to corticosteroid therapy prescribed for a suspicion of minimal change disease. It is most often associated with an autoimmune disease, predominantly lupus. We previously reported the occurrence of early-onset MN associated with semaphorin 3B in nine children and two adults.

IFCT-1502 CLINIVO: real-world evidence of long-term survival with nivolumab in a nationwide cohort of patients with advanced non-small-cell lung cancer.

Background: Immunotherapy using inhibitors targeting immune checkpoint programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) is currently the standard of care in patients with advanced non-small-cell lung cancer (NSCLC).

Materials And Methods: We carried out a nationwide cohort retrospective study of consecutive patients with advanced, refractory NSCLC who received nivolumab as second to later lines of treatment as part of the expanded access program. Key objectives were to assess the efficacy and safety of nivolumab and the efficacy of first post-nivolumab treatment.

The role of PLA2R antibody monitoring: what we know and what we do not know.

For a long time, kidney biopsy was the only diagnostic means for membranous nephropathy (MN) and proteinuria and serum creatinine were the only markers of disease activity. The discovery of the phospholipase A2 receptor (PLA2R) antibody in 2009 has induced a paradigm shift in both the diagnosis and monitoring of patients. Two serological tests are routinely used: the enzyme-linked immunosorbent assay (ELISA), which is quantitative, and the immunofluorescence assay (IFA), which is more sensitive.

When contactin antibodies hit the podocyte: a new neurorenal syndrome.

Membranous nephropathy can be associated with various etiologies and antigens. In this issue of Kidney International, Le Quintrec et al. described contactin-1 cell adhesion molecule as a novel target antigen shared by the peripheral nerve and podocyte in patients with neurological disease and membranous nephropathy.

Renal involvement in sarcoidosis: histological patterns and prognosis, an Italian survey.

Background: Granulomatous interstitial nephritis in sarcoidosis (sGIN) is generally clinically silent, but in <1% causes acute kidney injury (AKI).

Methods: This Italian multicentric retrospective study included 39 sarcoidosis-patients with renal involvement at renal biopsy: 31 sGIN-AKI, 5 with other patterns (No-sGIN-AKI), 3 with nephrotic proteinuria. We investigate the predictive value of clinical features, laboratory, radiological parameters and histological patterns regarding steroid response.

Membranous nephropathy.

Membranous nephropathy (MN) is a glomerular disease that can occur at all ages. In adults, it is the most frequent cause of nephrotic syndrome. In ~80% of patients, there is no underlying cause of MN (primary MN) and the remaining cases are associated with medications or other diseases such as systemic lupus erythematosus, hepatitis virus infection or malignancies.

Supplemented Low-Protein Diet May Delay the Need for Preemptive Kidney Transplantation: A Nationwide Population-Based Cohort Study.

Background: Although several studies suggest the benefit of a low-protein diet supplemented with amino acids and keto acids (sLPD) in delaying the initiation of hemodialysis, evidence on whether these nutritional approaches could delay the timing of preemptive transplantation is lacking.

Methods: Retrospective nationwide cohort study, from Taiwan's National Health Insurance Research Database. Patients having undergone a first preemptive kidney transplantation between 2001 and 2017 were identified and divided into two groups according to the presence of sLPD treatment or not.

Achieving Expert-Level Interpretation of Serum Protein Electrophoresis through Deep Learning Driven by Human Reasoning.

Background: Serum protein electrophoresis (SPE) is a common clinical laboratory test, mainly indicated for the diagnosis and follow-up of monoclonal gammopathies. A time-consuming and potentially subjective human expertise is required for SPE analysis to detect possible pitfalls and to provide a clinically relevant interpretation.

Methods: An expert-annotated SPE dataset of 159 969 entries was used to develop SPECTR (serum protein electrophoresis computer-assisted recognition), a deep learning-based artificial intelligence, which analyzes and interprets raw SPE curves produced by an analytical system into text comments that can be used by practitioners.

A Fresh Perspective on Monoclonal Gammopathies of Renal Significance.

Monoclonal gammopathies of renal significance (MGRS) encompass a remarkable variety of kidney diseases that result from intrinsic nephrotoxic properties of certain monoclonal Igs or their subunits. Effective disease-modifying treatments rely on the targeting of a malignant B-cell clone that may be demonstrable but often is quite hypothetical. Hence, convincing arguments for the genuine monoclonal character of the causative mono-isotypic Ig tissue deposits is needed for design of appropriate treatment strategies.

Real world data of efficacy and safety of erlotinib as first-line TKI treatment in EGFR mutation-positive advanced non-small cell lung cancer: Results from the EGFR-2013-CPHG study.

Background: Phase III clinical trials have demonstrated the merits of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKI) in the treatment of non-small cell lung cancer (NSCLC) patients with EGFR-activating mutations. Using a cohort of unselected patients treated with erlotinib, we sought to further describe patient and tumour characteristics, and to evaluate their progression-free survival (PFS) and overall survival (OS).

Methods: Overall, 44 pulmonologists included patients with the required characteristics as follows: Stage IIIB-IV NSCLC, EGFR-activating mutation, age≥18 years, and having to start erlotinib therapy or receiving erlotinib therapy as the first-line TKI, regardless of treatment-line.

Leg ulcers in childhood: A multicenter study in France.

Background: Leg ulcers in adults are a major public health concern. Their incidence increases with age and many causes have been identified, predominantly associated with vascular diseases. Leg ulcers in children and teenagers are less frequent.
