Comparative meta-analysis of cold snare polypectomy and endoscopic mucosal resection for colorectal polyps: assessing efficacy and safety.

Colorectal polyps are commonly treated with surgical procedures, with cold snare polypectomy (CSP) and endoscopic mucosal resection (EMR) being the two most prevalent techniques. This meta-analysis (PROSPERO ID: CRD42022336152) aimed to compare the efficacy and safety of CSP and EMR in the management of colorectal polyps. Comprehensive searches were conducted in PubMed, Embase, CINAHL, Web of Science, and Cochrane Library databases, covering publications up until June 2024.

Balanced Miscibility and Crystallinity by 2D Acceptors Enabled Halogen-Free Solvent-Processed Organic Solar Cells to Achieve 19.28% Efficiency.

Two highly crystalline 2D acceptors, ATIC-C11 and ATIC-BO, with acenaphthene-expanded quinoxaline central cores, have been demonstrated with very different characteristics in ternary organic solar cells (OSCs). The difference in side chains induces their distinctive molecular packing mode and unique crystal structure, in which ATIC-C11 displays a 3D structure with an elliptical framework, and ATIC-BO gives a rectangular framework. Their high crystallinity contributes to organized molecular packing in ternary devices, thus low energetic disorder and suppressed energy loss.

Clinical Efficacy of Virtual Reality Cave Automatic Virtual Environments (CAVE) for Chronic Musculoskeletal Pain in Older Adults: A Randomized Controlled Trial.

Objectives: To assess whether tai chi assisted by the Cave Automatic Virtual Environment (CAVE), a novel virtual reality (VR) technology, was superior to tai chi alone in managing chronic pain in older adults. CAVE may offer a promising alternative to head-mounted displays in chronic pain treatment.

Design: The study was a 12-week, 2-arm, parallel, randomized controlled trial implemented in VR and non-VR groups (N = 80, each arm = 40).

Histopathological Prognostic Factors of Surgically Treated HPV-Associated Oropharyngeal Squamous Cell Carcinoma: A Systematic Review and Meta-analysis.

Background: Human papilloma virus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) is rising in prevalence and is associated with better survival than HPV-negative OPSCC. In surgically treated HPV-negative OPSCCs, adverse pathologic features such as positive surgical margins, extra-nodal extension (ENE) and perineural invasion are well described to portend worse clinical outcomes. These adverse pathological features, however, are not validated prognostic markers among surgically treated HPV-positive OPSCCs.
