Study Objective: To explore the association between gabapentin use and the risk of dementia in patients with chronic pain, considering the rising concerns of dementia in an aging population and the potential cognitive impacts of chronic pain management.
Design: A nested case-control study utilizing data from a longitudinal health insurance database.
Setting: The study is based on a longitudinal health insurance database spanning 2000-2019 in Taiwan.
Patients: A total of 201,492 patients aged 50 years and older diagnosed with chronic pain between 2001 and 2017 were included. The study focused on individuals with chronic pain, excluding those diagnosed with dementia a year before or after their chronic pain diagnosis.
Intervention: Analysis of gabapentin prescription history was conducted, considering the cumulative dose from the chronic pain diagnosis date to the dementia diagnosis date or equivalent period for controls.
Measurement: Data included demographics, gabapentin prescription history, and comorbidities. Logistic regression was used to estimate odds ratios for dementia risk.
Main Results: No significant difference in the risk of dementia was found between low and high cumulative doses of gabapentin. The adjusted odds ratio for dementia risk associated with gabapentin use was 0.91 (95 % C.I. 0.83-1.01), indicating no substantial increase in risk.
Conclusion: Long-term Gabapentin therapy for chronic pain is not associated with a differential risk of dementia across dosage levels, irrespective of age or gender. Further study into its potential cognitive impacts is essential.

The trend of an annual increase in the detection of new cases of osteoarthritis (OA) and an increase in the number of patients with chronic lower back pain (LBP) calls for the search for new drugs and pharmaconutraceuticals with anti-inflammatory and chondroprotective properties. In 2019, approaches to the treatment of pain in OA significantly changed. In international and Russian clinical guidelines (CG), pharmaconutraceutical chondroitin sulfate (CS) and glucosamine sulfate (GS) are recommended for OA of different localization as a basic therapy.

BACKGROUND Arterioportal fistulas (APFs) are abnormal connections between the arterial and portal venous systems, leading to portal hypertension (PH) and symptoms such as gastrointestinal bleeding, splenomegaly, and hepatic pain. Symptoms typically appear by the age of 2 years in about 75% of cases. CASE REPORT A 7-year-old boy with an asymptomatic APF developed life-threatening complications following a Clostridium difficile infection.

Background: Lung cancer surgery is associated with a high incidence of chronic postsurgical pain (CPSP), which necessitates long-term analgesic prescriptions. However, while essential for managing pain, these have shown various adverse effects. Current guidelines recommend using peripheral nerve blocks over epidural anaesthesia for perioperative analgesia in minimally invasive thoracic surgery (MITS).

Background: Juvenile Idiopathic Arthritis (JIA) is a chronic pediatric illness, whereby youth experience physical, emotional and psychosocial challenges that result in reduced health related quality of life (HRQL). Peer mentoring has been shown to improve disease self-management in adults with chronic conditions, with mixed results in younger populations. Building on our pilot work - which supported the feasibility and initial effectiveness of the iPeer2Peer program - the objective of this study was to assess the clinical effectiveness of the program in youth with JIA through a waitlist randomized controlled trial.
