Purpose: To investigate the correlation between the presence of the Koebner phenomenon (KP) and clinical features of patients with vitiligo.
Patients And Methods: The clinical characteristic data, including age, age of onset, disease duration, gender, clinical stage, clinical type, family history, and comorbid immune-related diseases, of 1472 patients with/without KP were analyzed with SPSS 17.0 software.
Results: Of the 1472 patients, 290 (19.70%) were positive for KP. The clinical course (6.95 vs 5.62, P = 0.015), percentage of patients with progressive stage (78.97% vs 70.05%, P = 0.002), the acrofacial type (4.49% vs 1.69%, P = 0.004), comorbid immune-related diseases (28.29% vs 19.04%, P = 0.001) and lesion area ≥2% (47.24% vs 38.24%, P = 0.005) in KP-positive group were significantly greater than those in KP-negative group. Binary logistic regression analysis found that progressive stage (P = 0.003, OR = 1.60, 95% confidence interval (CI): 1.17-2.18), area of skin lesion ≥2% (P = 0.008, OR = 1.44, 95% CI: 1.10-1.88) and comorbid immune-related diseases (P = 0.001, OR = 1.63, 95% CI: 1.21-2.20) were significantly associated with KP.
Conclusion: The presence of KP in patients with vitiligo is associated with clinical progression, the acrofacial type, comorbid immune-related disease and a larger lesion area. This study suggested the presence of KP may be an indicator of disease activity and aggression, and underlay its importance in the management of disease.

Purpose: To investigate the correlation between the presence of the Koebner phenomenon (KP) and clinical features of patients with vitiligo.
Patients And Methods: The clinical characteristic data, including age, age of onset, disease duration, gender, clinical stage, clinical type, family history, and comorbid immune-related diseases, of 1472 patients with/without KP were analyzed with SPSS 17.0 software.
Background: Dupilumab has been added to National Cancer Comprehensive Network (NCCN) guidelines as a therapeutic strategy for managing certain cutaneous immune-related adverse events (cirAEs) from immune checkpoint inhibitor (ICI) therapy. However, little is known about the implications of dupilumab for cancer outcomes in this population. In this multi-institutional study, we evaluate the impact of dupilumab treatment on survival among ICI recipients.

Background: Selective serotonin reuptake inhibitors (SSRIs) are the primary choice for antidepressant therapy in cancer patients with depression. Programmed death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) play a critical role in immune checkpoint inhibitors. To date, there have been no studies reporting adverse events (AEs) associated with the real-world use of PD-1/PD-L1 inhibitors-SSRIs combination.

Background: Anxiety is a common psychological comorbidity in patients undergoing dialysis, yet its impact on treatment adherence and complication rates remains understudied. We designed a longitudinal observational study to investigate these relationships, based on the hypothesis that higher anxiety symptoms would be associated with increased complication rates and negatively associated with adherence to the dialysis regimen.
Aim: To investigate the relationship between anxiety symptoms, dialysis adherence, and complication rates in patients undergoing dialysis over a 24-month period.
Shared Genetics of Migraine and Gastrointestinal Disorders Implicates Underlying Neurologic Mechanisms Yet Heterogeneous Etiologies.

Background And Objectives: Migraine is strongly comorbid with irritable bowel syndrome (IBS), one of several gastrointestinal (GI) conditions that are distinguished by symptomatic profiles that are partly overlapping. Potential shared mechanisms of migraine and the GI conditions were investigated by assessing shared genetics on a genome-wide basis.
Methods: Analyses leveraged genome-wide summary statistics from large-scale genetic studies for migraine, including by aura status, IBS, peptic ulcer disease (PUD), gastrointestinal reflux (GERD), functional dyspepsia (FD), diverticular disease (DD), and the immune-related inflammatory bowel disease (IBD) or its constituents, ulcerative colitis (UC) and Crohn disease (CD).
