Background: Transradial access for angioplasty and percutaneous intervention (PCI) has become more popular across the world due to lower risk of bleeding and better patient comfort. It has been shown to be effective and feasible in the Western population. However, there is a relative paucity of similar data for small-statured females, especially from Asian countries. Given the increased theoretical risk of local complications due to smaller-sized radial arteries in such females, feasibility and safety of transradial PCI (rPCI) needs to be better established in this group.
Methods: We present observational data for rPCI from a 3-year period at a single tertiary care center in South Asia. Data were collected on all female patients who underwent rPCI from January 2005 to December 2007. Primary outcomes assessed were procedure failure rate and complication rate. Secondary outcomes included death, recurrence of myocardial infarction, anginal symptoms or other complaints. Outcomes were recorded post-procedurally in the hospital and after discharge for up to 6 months.
Results: A total of 93 patients were included for final data analysis. Average patient age was 57.5 ± 10.3 years, with average height of 151.7 ± 8.4 cm and average weight of 58.1 ± 12.5 kg. Seventy patients (75.3%) underwent angioplasty or percutaneous intervention (PCI) for ACS and 23 (24.7%) for chronic stable angina refractory to medical therapy. A total of 118 lesions were treated in 90 patients. Ninety-one lesions (77.1%) were classified as Type B2 and Type C according to modified American College of Cardiology/American Heart Association lesion morphology criteria. Three cases of procedure failure accounted for a failure rate of 3.23%. No specified complications were noted in any of the patients. At 6-month follow-up, no deaths were observed. Two patients developed acute myocardial infarction and 16 patients (17.7%) had recurrence of anginal symptoms.
Conclusion: Radial artery angioplasty and stenting is feasible and safe in Asian females. Increased theoretical risk of complication due to small-sized radial arteries in this subgroup is unlikely to be true. Success rates are likely to be good even with complex coronary inventions performed with transradial access.

Background: Therapeutic advancements for the polyglutamine diseases, particularly spinocerebellar degeneration, are eagerly awaited. We evaluated the safety, tolerability, and therapeutic effects of L-arginine, which inhibits the conformational change and aggregation of polyglutamine proteins, in patients with spinocerebellar ataxia type 6 (SCA6).
Methods: A multicenter, randomized, double-blind, placebo-controlled phase 2 trial (clinical trial ID: AJA030-002, registration number: jRCT2031200135) was performed on 40 genetically confirmed SCA6 patients enrolled between September 1, 2020, and September 30, 2021.
The role of brainstem biopsy and targeted therapies in pediatric diffuse midline glioma/diffuse intrinsic pontine glioma.

Pediatric diffuse midline glioma (DMG), including diffuse intrinsic pontine glioma (DIPG), are aggressive brainstem tumors with a dire prognosis, traditionally diagnosed based on MRI characteristics. The recognition that molecular characteristics may determine prognosis and response to therapy has led to a reevaluation of biopsy necessity. This comprehensive review addresses the evolving role of brainstem biopsies in diagnosing and managing these tumors - both within the context of a clinical trial and in routine clinical care.

Developing small organic molecular phototheranostic agents with second near-infrared (NIR-II) aggregation-induced emission (AIE) is paramount for the phototriggered diagnostic imaging and synchronous in situ therapy of cancer via an excellent balance of the excited states energy dissipations. In this study, a multifunctional iridium(III) complex is exploited by the coordination of an AIE-active N^N ancillary ligand with a trivalent iridium ion. The resultant complex DPTPzIr significantly outperforms its parent ligand in terms of absorption/emission wavelengths, reactive oxygen species (ROS) production, and photothermal conversion, which simultaneously endow DPTPzIr nanoparticles with matched absorption peak to commercial 808 nm laser, the longest NIR-II emission peak (above 1100 nm) among those previously reported AIE iridium(III) complexes, potentiated type-I ROS generation, and as high as 60.
