Background: Access site complications are reduced using radial percutaneous coronary intervention (PCI). There is concern that technical difficulties using this approach can delay achievement of reperfusion during primary or rescue PCI for acute myocardial infarction (AMI) especially in elderly patients.
Methods And Results: We studied 155 patients (pts) > or = 70 years who underwent primary or rescue PCI for AMI; radial (Group1; 87 pts) or femoral (Group2; 68 pts). Baseline characteristics, the amount of IIB/IIIA inhibitor, contrast and heparin used, and TIMI flow pre and post PCI were similar in both groups (P>0.05). Time from arrival in the catheterization laboratory to the first balloon inflation (Group 1: 44.0+/-21.5 versus Group 2 38.8+/-18.7 min) was also similar, but was significantly longer (61.2+/-11.1 min) compared to both groups in patients with a failed radial approach (7 pts, 8%). Angiographic success, and in-hospital MACE were also similar in the two groups, but vascular access site complications were significantly higher in Group 2 (0 versus 2.9%, P<0.05).
Conclusion: The use of the radial approach in elderly patients undergoing primary and rescue PCI, when successful, is safe and effective as the femoral approach, and leads to fewer vascular complications.

Purpose: Postherpetic neuralgia (PHN) is a type of refractory neuropathic pain that causes significant suffering, disability, economic loss, and medical burden. In this study, we aim to evaluate the efficacy and safety of interferon (IFN)-α1b injection into the intervertebral foramen of patients with PHN.
Patients And Methods: This is a study protocol for a randomized, double-blind placebo-controlled multicenter clinical trial.

Introduction: Breast cancer is the most common cancer in females. Surgery is the gold standard therapy, with modified radical mastectomy (MRM) being the most commonly performed procedure for breast cancer. Management of postoperative pain after MRM poses a clinical challenge and hence receives utmost priority.

Background: Our previous studies have established that the broad-spectrum anti-epileptic drug lamotrigine (LTG) confers protection against cognitive impairments, synapse and nerve cell damage, as well as characteristic neuropathologies in APP/PS1 mice, a mouse model of Alzheimer's disease (AD). However, the precise molecular mechanisms responsible for this protective effect induced by LTG remain largely elusive.
Objective: In this study, we aimed to investigate the mechanisms underlying the beneficial effects of LTG against AD.

Background: Laparoscopic sleeve gastrectomy (LSG) causes significant postoperative pain, necessitating effective multimodal analgesia strategies. This study evaluated the efficacy of the external oblique intercostal block (EOIB) in this context.
Methods: This prospective, randomized, controlled, single-blind study conducted between April and December 2023 included 60 patients who underwent LSG.
Lupus Nephritis Renal Response in a Real-World Setting in Argentina.

Objective: To identify the percentage of patients with incident lupus nephritis who achieved primary efficacy renal response (PERR) and complete renal response (CRR) after 2 years of treatment at a university hospital.
Methods: An observational study including patients with lupus with a first renal biopsy with nephritis class III, IV, or V, or combined, performed between years 2000 and 2018 and follow-up for over 2 years at a university hospital in Argentina. The proportion of patients with PERR and CRR at 1 and 2 years and the proportion of patients requiring rescue therapy were calculated.
