Single-arm clinical trials are useful to evaluate antiretroviral regimens in certain populations of HIV-infected treatment-naive patients for whom a randomized controlled trial is not feasible or desirable. They can also be useful to establish initial estimates of efficacy and safety/tolerability of novel regimens to inform the design of large phase III trials. In this article, we discuss key design considerations for such single-arm studies.

Importance: Retrieval strategies for children, adolescents, and young adults with relapsed classic Hodgkin lymphoma (cHL) aim to maintain efficacy while minimizing long-term toxic effects. Children, adolescents, and young adults with low-risk, relapsed cHL may benefit from replacing high-dose chemotherapy and autologous stem cell transplant with less intensive involved-site radiotherapy (ISRT).

Objective: To evaluate a risk-stratified, response-adapted, transplant-free approach for treatment of children, adolescents, and young adults with low-risk relapsed cHL with nivolumab plus brentuximab vedotin (BV) followed by BV plus bendamustine for patients with suboptimal response and ISRT (30.

Introduction: Water Jet Ablation Therapy (WJAT) and Holmium Laser Enucleation of the Prostate (HoLEP) represent two common surgical treatments for Benign Prostatic Hyperplasia (BPH). Despite their increasing use, there is no study between these two methods. We aim to evaluate their efficacy and safety through a network meta-analysis (NMA), providing critical insights for clinical decision-making in the management of moderate to severe lower urinary tract symptoms (LUTS) due to BPH.

Background: Non-clear cell renal cell carcinoma (nccRCC) represents a heterogeneous group of malignancies with substantial differences in morphology, genetic profiles, clinical behavior, and prognosis. Optimal treatment for nccRCC remains unclear, largely extrapolated from evidence available for clear cell renal cell carcinoma (ccRCC). This study aimed to compare the efficacy of current mainstream drug treatments for nccRCC to provide clinical treatment guidance for advanced cases.

Introduction And Objective: Surface electromyography (sEMG) measurements are a valid method for sublesional muscle activity following spinal cord injury (SCI). In the literature there are few reports evaluating the effect of robotic assisted gait training (RAGT) on the sEMG properties change in SCI patients. The aim of this study was to evaluate the influence of RAGT on observed change of sEMG, and in 64 incomplete SCI patients in the sub-acute stage in relation to functional scales.

The broad spectrum of clinical manifestations caused by peripheral arterial disease [PAD] and the morphologic heterogeneity of associated atherosclerotic lesions present a considerable management challenge. Endovascular interventions are recognized an effective treatment for PAD. Within this revascularization strategy the role of atherectomy debulking modalities continue to evolve.
