Pharmacokinetics, efficacy, and safety of subcutaneous versus intravenous rituximab in previously untreated Chinese patients with CD20+ diffuse large B-cell lymphoma: a phase II randomized controlled trial.

Subcutaneous (SC) rituximab has demonstrated advantages over intravenous (IV) administration; however, insufficient data exist on its use with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in Chinese patients with diffuse large B-cell lymphoma (DLBCL). This multicenter, phase II, randomized, controlled study was conducted across China between February 2021 and October 2022. Fifty adult patients with previously untreated CD20-positive DLBCL were randomized to receive one cycle of IV rituximab and seven cycles of SC rituximab (R-CHOP;  = 26), or eight cycles of IV rituximab (R-CHOP;  = 24), combined with six or eight cycles of CHOP.

The Reinforced Cementoplasty with Spindles Technique.

Reinforced cementoplasty with spindles is a recently introduced technique that is mainly used for pathological fractures or for bone metastases at risk of fracture in locations with shear stresses. The technique is less challenging to perform than percutaneous screw insertion and does not require equipment sterilization. No general anesthetic is required.

Evaluation of T Cell Response to SARS-CoV-2 in Kidney Transplant Recipients Receiving Monoclonal Antibody Prophylaxis and the Utility of a Bivalent mRNA Vaccine Booster Dose.

Monoclonal antibodies have been administered to kidney transplant recipients (KTRs) with a poor or non-responder status to SARS-CoV-2 vaccination. The cellular response to SARS-CoV-2 has been poorly studied in this context. We assessed the T cell response to SARS-CoV-2 in 97 patients on the day of the injection of tixagevimab/cilgavimab using an IFNγ enzyme-linked immunospot assay (ELISPOT).

Carfilzomib-associated thrombotic microangiopathy: clinical features and outcomes.

Background: Carfilzomib, a new proteasome inhibitor indicated for patients with relapsed/refractory myeloma, has been associated with cases of thrombotic microangiopathy (CFZ-TMA). The role of variants in the complement alternative pathway and therapeutic potential of complement blockade with eculizumab remain to be determined.

Methods: We report 37 cases of CFZ-TMA recorded in the French reference center for TMA with their clinical characteristics, genetic analysis and outcome according to treatments.

Endovascular retrieval of a migrated contraceptive implant into the pulmonary artery : case report and review of literature.

Background: The migration of contraceptive devices into pulmonary arteries is extremely rare, reported to be 1 in 100,000.

Case Presentation: A 19-year-old female presented no sensation of a contraceptive implant in her arm which had been placed one year prior. A CT scan confirmed that the implant had migrated into the left lower segmentary pulmonary artery.

Anti SARS-CoV-2 Monoclonal Antibodies in Pre-Exposure or Post-Exposure in No- or Weak Responder to Vaccine Kidney Transplant Recipients: Is One Strategy Better than Another?

Kidney transplant recipients (KTRs) are likely to develop severe COVID-19 and are less well-protected by vaccines than immunocompetent subjects. Thus, the use of neutralizing anti-SARS-CoV-2 monoclonal antibodies (mAbs) to confer a passive immunity appears attractive in KTRs. This retrospective monocentric cohort study was conducted between 1 January 2022 and 30 September 2022.

Biliary atresia: The profile, management and outcome of patients treated at a tertiary hospital in central South Africa.

Background: Biliary atresia (BA) is an obstructive inflammatory disease of the bile ducts. Without intervention, the disease rapidly progresses to liver cirrhosis and fibrosis, with end-stage liver failure and death occurring within the first 3 years of life. It is the most common indication for liver transplantation (LT) in the paediatric population.

Assessment of epidemiology and outcomes of adult patients with kidney-limited thrombotic microangiopathies.

Thrombotic microangiopathies (TMA) are usually associated with hematological features (RH-TMA). The epidemiology of TMA limited to kidneys (RL-TMA) is unclear Therefore, patients with TMA and native kidney biopsies were identified during 2009-2022 in 20 French hospitals and results evaluated. RL-TMA was present in 341/757 (45%) patients and associated with lower creatinine levels (median 184 vs 346 μmol/L) than RH-TMA.

Renal replacement therapy initiation strategies in comatose patients with severe acute kidney injury: a secondary analysis of a multicenter randomized controlled trial.

Purpose: The effect of renal replacement therapy (RRT) in comatose patients with acute kidney injury (AKI) remains unclear. We compared two RRT initiation strategies on the probability of awakening in comatose patients with severe AKI.

Methods: We conducted a post hoc analysis of a trial comparing two delayed RRT initiation strategies in patients with severe AKI.

ROX index performance to predict high-flow nasal oxygen outcome in Covid-19 related hypoxemic acute respiratory failure.

Background: Given the pathophysiology of hypoxemia in patients with Covid-19 acute respiratory failure (ARF), it seemed necessary to evaluate whether ROX index (ratio SpO/FiO to respiratory rate) could accurately predict intubation or death in these patients initially treated by high-flow nasal oxygenation (HFNO). We aimed, therefore, to assess the accuracy of ROX index to discriminate between HFNO failure (sensitivity) and HFNO success (specificity).

Methods: We designed a multicentre retrospective cohort study including consecutive patients with Covid-19 ARF.

Evaluation of preventive tract embolization with standardized gelatin sponge slurry on chest tube placement rate after CT-guided lung biopsy: a propensity score analysis.

Background: To evaluate the effect of tract embolization (TE) with gelatin sponge slurries during a percutaneous lung biopsy on chest tube placement and to evaluate the predictive factors of chest tube placement.

Methods: Percutaneous CT-guided lung biopsies performed with (TE) or without (non-TE) tract embolization or between June 2012 and December 2021 at three referral tertiary centers were retrospectively analyzed. The exclusion criteria were mediastinal biopsies, pleural tumors, and tumors adjacent to the pleura without pleural crossing.
