SREs

BACKGROUND: Bone-targeted therapy (BTT) including zoledronic acid (ZA) and denosumab decreases the risk of skeletal-related events (SREs) in patients with metastatic breast cancer (MBC) and bone metastasis. The impacts from prolonged BTT on SREs and BTT-associated harms are unknown and are becoming important to understand as these patients survive for longer periods. METHODS AND MATERIALS: We conducted a retrospective study of 224 patients with MBC and bone metastasis who survived for more than 2 years after diagnosis and received treatment at our institution between 2016 and 2021...

During the course of lung cancer progression, bone metastases occur in about 40% of patients. Common complications associated with bone metastases in lung cancer patients include musculoskeletal pain, pathologic fractures, spinal cord compression, and hypercalcemia. We discuss the efficacy of bone-modifying agents (BMAs) in reducing skeletal-related events (SREs) and improving cancer-related outcomes, particularly in patients with stage IV non-small-cell lung cancer with bone metastases. In addition, the combined effects of BMAs with radiotherapy or immunotherapy in reducing SREs in patients with lung cancer and bone metastases are explored...

It is difficult to perfectly analyze the enhancement mechanism of two-dimensional (2D) materials and their combination with precious metals as surface enhanced Raman scattering (SERS) substrates using chemical enhancement mechanisms. Here, we propose a new mentality based on the coupling effect of neighboring electron orbitals to elucidate the electromagnetic field enhancement mechanism of single-atom-layer Au clusters embedded in double-layer 2H-TaS2 for SRES sensing. The insertion of Au atoms into the 2H-TaS2 interlayer was verified by XRD, AFM, and HRTEM, and a SERS signal enhancement of 2 orders of magnitude was obtained compared to the pure 2H-TaS2 ...

BACKGROUND: Robot-assisted gait training is incorporated into guidelines for stroke rehabilitation. It is a promising tool combined with conventional therapy for low ambulatory patients. The heavy weight and bulky appearance of a robotic exoskeleton limits its practicality. On the other hand, soft robotic exosuit (SRE) based on its light weight and inconspicuous property, is better tolerated by patients in daily life. The aim of this study is to review the efficacy of the SRE with regard to walking ability and biomechanical properties in stroke patients...

Pre-mRNA splicing, a key process in gene expression, can be therapeutically modulated using various drug modalities, including antisense oligonucleotides (ASOs). However, determining promising targets is impeded by the challenge of systematically mapping splicing-regulatory elements (SREs) in their native sequence context. Here, we use the catalytically dead CRISPR- Rfx Cas13d RNA-targeting system (dCas13d/gRNA) as a programmable platform to bind SREs and modulate splicing by competing against endogenous splicing factors...

In order to improve the detection performance of surface-enhanced Raman scattering (SERS), a low-cost Au@Ag nanorods (Au@Ag NRs) substrate with a good SERS enhancement effect was developed and applied to the detection of malachite green (MG) in aquaculture water and crayfish. By comparing the SERS signal enhancement effect of five kinds of Au@Ag NRs substrates with different silver layer thickness on 4-mercaptobenzoic acid (4-MBA) solution, it was found that the substrate prepared with 100 µL AgNO3 had the smallest aspect ratio (3...

The clinical relevance of bone metastases (BM) in advanced pancreatic neuroendocrine tumours (PanNETs) is poorly described. We analysed 314 consecutive PanNET patients treated at the European Neuroendocrine Tumour Society (ENETS) Center Essen between 2009 and 2021 in terms of the occurrence and clinical and prognostic impact of BM using hybrid imaging with 68Ga-DOTATOC PET/CT. According to UICC staging, 171/314 (54.5%) patients had stage IV PanNETs. BM was diagnosed in 62/171 (36.3%) patients. Initially, 35% of BMs were visible by pathological tracer uptake only...

This study aimed to evaluate the efficacy of combining immune checkpoint inhibitors (ICIs) and anti-angiogenic agents in treating lung cancer patients with bone metastases (BMs), as it is unclear whether this combination is effective for this condition. Non-small cell lung cancer patients with BMs receiving ICIs were divided into experimental and control groups based on anti-angiogenic treatment. Progression-free survival (PFS) and overall survival (OS) were evaluated using the Kaplan-Meier method, with log-rank test for comparisons...

Introduction  Skeletal metastasis is catastrophic in patients with renal cell carcinoma (RCC), leading to skeletal-related events (SRE) such as nerve entrapment, hypercalcemia and even pathological fractures, which may require surgical intervention. The nature of the bone metastasis in advanced RCC is large, destructive, hyper-vascular and mostly lytic. The present retrospective analysis aims to identify potential risk factors for predicting SREs in advanced RCC with bone metastasis. Methods The clinical data of 42 patients with RCC and bone metastasis and at least one episode of SRE were reviewed, and the correlations between erythrocyte sedimentation rate (ESR), alkaline phosphatase (ALP), C-reactive protein (CRP), haemoglobin (Hb), carcinoembryonic antigen (CEA) and bone metastases were analysed...

BACKGROUND: Denosumab entered the Chinese market for the first time in 2020. Since it is a short period of time, there is a lack of data on its effectiveness and safety in Chinese people. The objective of this study was to evaluate the effectiveness and safety of denosumab in delaying skeletal-related events (SREs) in patients with breast cancer metastatic to bone. METHODS: The study retrospectively analyzed data from breast cancer patients with bone metastases (BM) who were treated with denosumab in the First Affiliated Hospital of Nanjing Medical University from September 2020 to January 2022...

The clinical manifestations of bone metastases are diversified while many sites remain asymptomatic at early stage. As the early diagnosis method is not perfect and the early symptoms of tumor bone metastasis are not typical, bone metastasis is not easy to be detected. Therefore, the search for bone metastasis-related markers is effective for timely detection of tumor bone metastases and the development of drugs to inhibit bone metastases. As a result, bone metastases can only be diagnosed when symptoms are found, increasing the risk of developing skeletal-related event (SREs), which significantly impairs the patient's quality of life...

BACKGROUND: Real-world data on optimal cancer pain management remain scarce. We describe prescription patterns of analgesics in Japanese cancer patients with bone metastases. METHODS: National hospital-based claims data were analyzed. Adults with first diagnosis of cancer during 2015-2019 and first diagnosis of bone metastasis after the initial cancer diagnosis were included. Skeletal-related events (SREs) were identified with disease and receipt codes. RESULTS: Among the 40,507 eligible patients (age [mean ± SD], 69...

Islet transplantation stabilizes glycemic control in patients with complicated diabetes mellitus. Rapid functional decline could be due to islet allograft rejection. However, there is no reliable method to assess rejection and treatment protocols are absent. We aimed to characterize diagnostic features of islet allograft rejection and assess effectiveness of high-dose methylprednisolone treatment. Over a median follow-up of 61.8 months 22% (9/41) of islet transplant recipients experienced 10 suspected rejection episodes (SREs)...

BACKGROUND: Zoledronic acid (ZA) reduces the incidence of skeletal-related events (SREs) in patients with bone metastases from solid tumors. However, the optimal dosing interval of ZA for patients with lung cancer is uncertain. METHODS: We conducted a randomized, open-label, feasibility phase 2 trial at eight Japanese hospitals. Patients with bone metastases from lung cancer were randomly assigned to receive either 4 mg of ZA every four weeks (4wk-ZA) or every eight weeks (8wk-ZA)...

BACKGROUND: Sleep, particularly rapid eye movement (REM) sleep, has been found to be associated with Sleep-related erections (SREs). While Rigiscan is currently a more accurate method for monitoring nocturnal erectile events, the Fitbit, a smart wearable device, shows great potential for sleep monitoring. OBJECTIVES: To analyze the relationship between SREs and sleep by recruiting sexually active, healthy men for simultaneous monitoring of sleep and nocturnal penile tumescence and rigidity (NPTR)...

Bone is a preferred metastatic site of advanced breast cancer and the 5-year overall survival rate of breast cancer patients with bone metastasis is only 22.8%. Targeted inhibition of osteoclasts can treat skeletal-related events (SREs) in breast cancer patients. Polyphyllin VII (PP7), a pennogenyl saponin isolated from traditional Chinese herb Paris polyphylla, exhibits strong anti-inflammatory and anti-cancer activities. In this study, we evaluated the effect of PP7 on metastatic breast cancer-induced bone destruction in vivo and the underlying mechanisms...

Flexible surface enhanced Raman spectroscopy (SERS) nanosensors, constructed by integration of plasmonic nanostructures with polymeric substrates, have received increasing research interests for recent decades. When compared to abundant works on optimization of the plasmonic nanostructures, the research involving the influence of polymeric substrates on analytical performance of resultant flexible SESR nanosensors is unexpectedly limited. Herein, the ultra-thin silver layer has been deposited on the electrospun polyurethane (ePU) nanofibrous membranes via vacuum evaporation to prepare the flexible SRES nanosensors...

Denosumab, an inhibitor of receptor activator of nuclear factor kappa-B ligand, reduces skeletal-related events (SREs) and is approved for solid tumors with bone metastases. We studied long-term denosumab efficacy and safety because real-world data is scarce. This single-arm, single-center retrospective study included denosumab-treated breast cancer patients with bone metastases. Kaplan-Meier survival curves assessed exposure, SREs, osteonecrosis of the jaw (ONJ), and death. 132 patients were enrolled. The median denosumab exposure was 28...
