The most critical complication to watch out for after receiving a lung transplant is Chronic Lung Allograft Dysfunction (CLAD). Once CLAD develops, there are no universally effective treatments available. Therefore, preventing this complication takes top priority for those who have undergone a lung transplant. One of the primary immunosuppressing medications used in lung transplant recipients is calcineurin inhibitors.

There are only two calcineurin inhibitors: cyclosporine and tacrolimus. Each has different formulations, such as once-daily slow-release tacrolimus, twice-daily immediate-release tacrolimus, and twice-daily cyclosporine. While these medications share the same goal of preventing rejection, it is unclear whether they are equally effective. CLAD encompasses a range of clinical manifestations that ultimately lead to the transplanted lung losing its normal function.

The presentation of CLAD can vary among patients, with some experiencing an obstructive ventilatory defect, others having a restrictive defect, and some exhibiting a combination of both. Unfortunately, once CLAD develops, lung function does not improve. In the absence of effective treatments, strategies to prevent CLAD are crucial.

A recent study published in the International Society for Heart and Lung Transplantation Thoracic Organ Transplant Registry data found a significant survival benefit between using tacrolimus versus cyclosporine after lung transplantation. Out of 22,222 individuals with data on chronic lung allograft dysfunction treatment, 88.6% received immediate-release tacrolimus. The participants taking immediate-release tacrolimus had a much lower rate of experiencing CLAD than those who took twice-daily cyclosporine.

Michael Combs, an assistant professor of pulmonary diseases and internal medicine at Michigan Medicine, led the research team conducting this study. Combs highlighted the positive findings for twice-daily immediate-release tacrolimus in this study, stating that it should reassure transplant patients and providers that using this formulation is the superior treatment to cyclosporine.

“This present study should reassure transplant patients and providers twice-daily tacrolimus — and not only once-daily tacrolimus — is the superior treatment to cyclosporine,” said Combs. “Importantly, in our study we found that twice-daily tacrolimus not only resulted in lower rates of CLAD relative to cyclosporine, but it was also associated with improved overall survival after lung transplantation. This is an important, patient-centered finding which has not been previously demonstrated.”

In conclusion, the most effective prevention method for complications post-lung transplant is using tacrolimus, regardless of its formulation. This treatment offers a significant advantage over cyclosporine in preventing CLAD and improving overall survival after lung transplantation. Future research will need to investigate whether once-daily medication regimens are superior to twice-daily formulations.

The University of Stuttgart has made a groundbreaking discovery in the field of physics, where researchers have successfully manipulated light to exhibit extraordinary properties. By interacting with a metal surface, they have created “skyrmion bags” of light that demonstrate entirely new behaviors. This achievement was published in Nature Physics and marks another significant chapter in the emerging field of skyrmion research.

Skyrmions are mathematical descriptions of vortex-like structures that help researchers better understand fundamental physical relationships. In recent years, this theoretical concept has been confirmed experimentally across various areas, including magnetic solids and material surfaces. Prof. Harald Giessen’s team at the University of Stuttgart has now investigated whether light impinging on a structured gold surface can behave like skyrmion bags with specific symmetries.

The researchers etched fine grooves in the shape of two twisted hexagons into the gold surface, generating a skyrmion light field for each hexagon. When they observed a superposition of these skyrmion light fields, the skyrmion bags formed. What’s even more striking is that the researchers were able to vary the number of skyrmions gathered within the skyrmion bags by adjusting the degree to which the light fields were twisted relative to one another.

This breakthrough has sparked imagination in terms of potential technical applications. While still fundamental physics, these light-field skyrmions exhibit extraordinary properties that could lead to innovations in microscopy. With a suitable material, researchers may be able to achieve resolutions with specialized microscopes that would otherwise be impossible due to the limits set by the wavelength of light.

Giessen’s team collaborated with researchers at the University of Duisburg-Essen for experimental verification and the Technion in Haifa for theoretical description. As research continues to unfold, it will be exciting to see the potential applications of this discovery and how it can shape our understanding of physical phenomena.

The article discusses how a study conducted by researchers at Johns Hopkins Kimmel Cancer Center found that older adults with cancer respond just as well to immune checkpoint inhibitors as younger patients. The study examined immune cells and proteins in the blood of about 100 patients treated with these therapies, finding equal benefits in both age groups but differences in their immune responses.

The researchers discovered that T cells, which help destroy damaged cells or bacteria, looked like they’d been “around the block” in older patients, suggesting they may be less ready to respond to threats without additional treatments. These differences may make immune checkpoint inhibitors even more beneficial for older patients.

The study aims to understand age-related differences in immune responses to cancer therapies and develop new strategies to personalize treatments based on patient-level factors. This research has the potential to improve treatment outcomes for older adults, who often have worse cancer treatment outcomes than their younger peers.

The article also highlights the importance of considering age-related changes when developing cancer therapies, as this can help identify new strategies and tailor treatments more effectively to individual patients’ needs.

Overall, this study provides encouraging evidence that immunotherapy can be effective across age groups, despite age-related immune system differences. The findings have significant implications for improving treatment outcomes in older adults with cancer.
