Glaucoma remains a leading cause of blindness globally. Minimally invasive treatment techniques are rapidly expanding the availability of therapeutic options for glaucoma. These include devices aimed at enhancing outflow through the subconjunctival space, Schlemm's canal, and suprachoroidal space, sustained-release drug delivery devices, and extraocular devices aiming to reduce glaucomatous progression through other novel means. In this review, we provide an overview of several novel devices either newly available or in development for the medical and surgical management of glaucoma. Further studies are required to determine the long-term efficacy of these devices and how they will integrate into the current landscape of glaucoma management.

Leadless pacing technology now includesdedicated atrial helix-fixation leadless pacemakers (LPs), expanding theapplication of leadless devices for patients with sinus node dysfunction andatrioventricular block during sinus rhythm. This first reportedcase-series of atrial LPs describes and discusses the potential use-casescenarios of recently approved helix-fixation atrial LPs. The article highlights important concepts regarding their use, including implantationtechniques, programming, battery conservation, and the low rate of progressionof AV block in patients implanted with AAI(R) pacemakers.

Reel's syndrome (RS) is an unusual cause of pacemaker lead dislodgement. We present the case of a 59-year-old female patient with Down syndrome (DS) implanted with a dual-chamber endovascular pacemaker due to symptomatic sinus node disfunction, reporting several syncopal episodes in last days and showing abnormal electrical parameters at the 2-months follow-up due to RS. The malfunctioning device was removed and an endocardial leadless pacing system was implanted.

Half-metallic magnetism, characterized by metallic behavior in one spin direction and semiconducting or insulating behavior in the opposite spin direction, is an intriguing and highly useful physical property for advanced spintronics because it allows for the complete realization of 100% spin-polarized current. Particularly, half-metallic antiferromagnetism is recognized as an excellent candidate for the development of highly efficient spintronic devices due to its zero net magnetic moment combined with 100% spin polarization, which results in lower energy losses and eliminates stray magnetic fields compared to half-metallic ferromagnets. However, the synthesis and characterization of half-metallic antiferromagnets have not been reported until now as the theoretically proposed materials require a delicate and challenging approach to fabricate such complex compounds.

Purpose: Achieving precise postoperative alignment is critical for the long-term success of total knee arthroplasty (TKA). Long-leg standing radiograph (LLR) at 6 weeks post-op is the gold standard for assessing alignment, but its reliance on weight-bearing and positioning makes it less practical in the early postoperative period. Supine computed tomography scanogram (CTS) offers a potential alternative.

The nonlinear optical response in graphene is finding increasing applications in nanophotonic devices. The activation and enhancement of second harmonic generation (SHG) in graphene, which is generally forbidden in monolayer and AB-stacked bilayer graphene due to their centrosymmetry, is of urgent need for nanophotonic applications. Here, we present a comprehensive study of SHG performance of twisted multilayer graphene structures based on stacking engineering.
