The aim of this study is to evaluate the role of indocyanine green (ICG) injection in fluorescence-guided lymphatic mapping during laparoscopic colon cancer resection. This is a single-center prospective single-arm pilot clinical study that will include at least 25 patients with resectable colon cancer. All enrolled patients will undergo intraoperative subserosal ICG-guided lymphatic mapping before dissection, and intravenous ICG perfusion assessment before anastomosis. The primary goal is to determine the proportion of analyzable pN+ patients in whom all metastatic lymph nodes identified on final histopathology are located within the ICG-mapped lymphatic basin.

Introduction Diabetic peripheral neuropathy (DPN) is among the most common chronic complications of diabetes mellitus and represents a major cause of morbidity, impaired quality of life, sleep disturbance, chronic pain, and functional disability.(Kurz et al., 2026) The pathogenesis of DPN is multifactorial and involves oxidative stress, chronic inflammation, endothelial dysfunction, mitochondrial injury, and microvascular ischemia, leading to progressive nerve damage.(Yang et al., 2025) Despite the availability of symptomatic therapies such as gabapentin, pregabalin, and duloxetine, many patients continue to experience persistent neuropathic symptoms, poor sleep quality, and impaired daily functioning. Existing pharmacological therapies are often associated with incomplete response, adverse effects, and high economic burden.(Kaye et al., 2025) Recently, vitamin D has attracted attention beyond its classical role in calcium and bone metabolism. Experimental and clinical evidence suggest that vitamin D possesses neuroprotective, anti-inflammatory, immunomodulatory, and antioxidative properties. Vitamin D receptors are widely distributed in neuronal tissues, Schwann cells, and immune cells, suggesting a potential role in nerve repair and modulation of neuropathic pain pathways.(Liu et al., 2025) Several observational studies have demonstrated a high prevalence of vitamin D deficiency among patients with diabetic neuropathy, and low serum vitamin D levels have been associated with increased neuropathic pain severity and poorer quality of life. However, available interventional studies remain limited and have produced inconsistent findings regarding the therapeutic benefit of vitamin D supplementation in DPN.(Ou et al., 2021) Therefore, this study aims to evaluate whether vitamin D supplementation can improve neuropathic pain, sleep quality, and health-related quality of life among patients with diabetic peripheral neuropathy.

It has been proposed that altered scapular muscle function can contribute to alterations in shoulder kinematics, which often lead to SD and are frequently associated with other shoulder pathologies, such as RC tears, labrum tears, impingement syndrome, and glenohumeral joint instability. However, whether SD leads to the development of these diseases or is a consequence has yet to be clarified. Changes in scapular kinematics can be attributed not only to altered scapular recruitment patterns (e.g., altered serratus anterior muscle activity) or muscle performance (e.g., force imbalance in the upper and lower trapezius muscles) but also to flexibility deficits in the soft tissue surrounding the scapula, which may restrict normal scapular movement during daily activities and sport- specific movements. Although many studies have investigated the optimal management method, to date, there is no consensus. Conservative approaches involve not only physiotherapy but also other techniques, such as extracorporeal shockwave therapy.

The primary goal of this cross-sectional study is to assess risk factors/predictors for dysphagia severity in RA. The secondary goals include demonstrating whether flexible fiberoptic pharyngolaryngoscopy can diagnose joint-affection-induced dysphagia in patients with rheumatoid arthritis (RA) and whether both oropharyngeal and esophageal dysphagia are present among these patients. The main questions it aims to answer are * What are the predictors that are associated with dysphagia severity via flexible fiberoptic pharyngolaryngoscopy in rheumatoid arthritis patients? * Whether flexible fiberoptic pharyngolaryngoscopy can diagnose joint-affection-induced dysphagia in patients with RA? * Whether both oropharyngeal and esophageal dysphagia are present in patients with RA?

This study compares the safety and efficacy of three endoscopic enucleation techniques for large prostates (\>100 mL) in patients with benign prostatic hyperplasia (BPH): Thulium Fiber Laser Enucleation (ThuFLEP), Holmium Laser Enucleation (HoLEP), and Bipolar Enucleation (B-TUEP). Ninety male patients with severe lower urinary tract symptoms (IPSS ≥20, Qmax ≤10 mL/s) who failed medical therapy will be randomized 1:1:1 into three groups of 30. Primary outcomes include IPSS, quality of life score, maximum flow rate (Qmax), and post-void residual at 1, 3, and 6 months postoperatively. Secondary outcomes include operative time, enucleation efficiency, blood loss, catheterization duration, hospital stay, and complication rates assessed by the Clavien-Dindo classification.

The goal of this clinical trial is to learn if ultrasound-guided nerve root injections work as well as fluoroscopy (X-ray)-guided injections to treat lower back and leg pain caused by irritated nerves (lumbosacral radiculopathy) in adults aged 18 to 75 years old. The main questions it aims to answer are: * Does ultrasound guidance lower pain as effectively as fluoroscopy guidance after 3 months? * Does one method help participants recover their ability to do daily activities better than the other? * Are ultrasound-guided injections as fast and safe for participants as fluoroscopy-guided injections? Researchers will compare ultrasound-guided nerve root injections to fluoroscopy-guided nerve root injections to see if ultrasound works to treat the pain just as well while allowing participants to avoid radiation exposure. Participants will: * Receive one targeted nerve injection of medication (a steroid and numbing medicine) in their lower back using either ultrasound or fluoroscopy to guide the needle. * Stay at the clinic for 30 to 60 minutes after the procedure so researchers can check their safety. * Attend checkups at 1 week, 1 month, and 3 months to answer survey questions about their pain levels and daily functioning.

This randomized controlled trial will compare three pelvic floor-based treatment modalities in men with lifelong premature ejaculation: electromagnetic pelvic floor stimulation, biofeedback-assisted pelvic floor muscle training, and conventional pelvic floor muscle training. A total of 150 men aged 18 to 50 years with lifelong premature ejaculation and stopwatch-measured intravaginal ejaculatory latency time of less than 1 minute will be randomly assigned to one of the three treatment groups. The primary outcome will be the change in intravaginal ejaculatory latency time from baseline to the end of treatment at 6 weeks. Secondary outcomes will include changes in Premature Ejaculation Diagnostic Tool score, International Index of Erectile Function-5 score, patient-reported ejaculatory control, sexual satisfaction, partner satisfaction, treatment adherence, and adverse events.
