Background: In the United States, patients aged >75 years are the most rapidly growing segment in the population, with an expected increase of 126% by 2050. These patients account for >70% of the pacemakers and up to two thirds of the implantable cardioverter-defibrillators implanted annually. Our aim was to explore the clinical outcomes of device complications in the octogenarian population.
Methods And Results: We performed a retrospective chart review of 506 patients undergoing laser lead extraction from January 2004 to September 2009. This population was divided into the following 2 groups based solely on age: octogenarians and nonoctogenarians. These 2 groups were compared on the basis of several characteristics and clinical outcomes. There were 118 patients in the octogenarian group (78 men) and 388 in the nonoctogenarians group (301 men) aged 85±3.8 and 64.2±12.4 years, respectively. A total of 253 leads (atrial, 99; ventricular, 145; coronary sinus, 9) were removed from the patients in the octogenarian group, and 814 leads (atrial, 295; ventricular, 442; coronary sinus, 77) were removed from the patients in the nonoctogenarian group. The main indication for extraction for both groups was infection. The lead implant duration was 59.6±52.8 and 38.6±43.9 months for octogenarians and nonoctogenarians, respectively. There was no significant difference with respect to the proportion of minor (P=0.65), major (P=0.56), and total (P=0.50) complications.
Conclusions: Laser lead extraction is demonstrated to be a safe and effective treatment method in octogenarian patients with multiple comorbidities.

Background: Caesarean section (CS) is the most common inpatient surgical procedure performed in Canada. CS is known to cause moderate-to-severe pain, which is suggested to be associated with postpartum depression and persistent pain. Existing limitations in multimodal analgesia and conscious attempts to avoid opioids highlight the need for non-pharmacological strategies.

The effects that arise in this context can lead to the modulation of individual field components and the transformation of the overall light field. In this study, we investigate the impact of phase and polarization distributions with radial dependencies in polar coordinates on the longitudinal component of laser beams passing through a transmissive spatial light modulator (SLM) based on twisted nematic liquid crystals.

The evolution of photosynthetic reaction centers (RCs) from anoxygenic bacteria to higher-order oxygenic cynobacteria and plants highlights a remarkable journey of structural and functional diversification as an adaptation to environmental conditions. The role of chirality in these centers is important, influencing the arrangement and function of key molecules involved in photosynthesis. Investigating the role of chirality may provide a deeper understanding of photosynthesis and the evolutionary history of life on Earth.

Transition metal carbides, nitrides, and carbonitrides (MXenes) have emerged as a promising class of 2D materials that can be used for various applications. Recently, a new form of high-entropy MXenes has been reported, which contains an increased number of elemental species that can increase the configurational entropy and reduce the Gibbs free energy. The unique structure and composition lead to a range of intriguing and tunable characteristics.

Chiral hybrid organic-inorganic metal halides (HOMHs) hold great promise in broad applications ranging from ferroelectrics, spintronics to nonlinear optics, owing to their broken inversion symmetry and tunable chiroptoelectronic properties. Typically, chiral HOMHs are constructed by chiral organic cations and metal anion polyhedra, with the latter regarded as optoelectronic active units. However, the primary design approaches are largely constrained to regulation of general components within structural formula.
