Exposure to air pollutants has been now associated with detrimental effects on a variety of organs, including the heart, lungs, GI tract, and brain. However, recently it has become clear that pollutant exposure can also promote the development/exacerbation of a variety of skin conditions, including premature aging, psoriasis, acne, and atopic dermatitis. Although the molecular mechanisms by which pollutant exposure results in these cutaneous pathological manifestations, it has been noticed that an inflammatory status is a common denominator of all those skin conditions. For this reason, recently, the activation of a cytosolic multiprotein complex involved in inflammatory responses (the inflammasome) that could promote the maturation of proinflammatory cytokines interleukin-1β and interleukin-18 has been hypothesized to play a key role in pollution-induced skin damage. In this review, we summarize and propose the cutaneous inflammasome as a novel target of pollutant exposure and the eventual usage of inflamminterleukin-18 has been hypothesized to play a key role in pollution-induced skin damage. In this review, we summarize and propose the cutaneous inflammasome as a novel target of pollutant exposure and the eventual usage of inflammasome inhibitor as new technologies to counteract pollution-induced skin damage. Possibly, the ability to inhibit the inflammasome activation could prevent cutaneous inflammaging and ameliorate the health and appearance of the skin. The landmark National Aeronautics and Space Administration Twins Study represented an integrated effort to launch human space life science research into the modern age of molecular- and "omics"-based studies. As part of the first One-Year Mission aboard the International Space Station, identical twin astronauts Scott and Mark Kelly were the subjects of this "out of this world" research opportunity. Telomeres, the natural ends of chromosomes that shorten with cell division and a host of lifestyle factors and stresses, are key molecular determinants of aging and aging trajectories. We proposed that telomere length dynamics (changes over time) represent a particularly relevant and integrative biomarker for astronauts, as they reflect the combined experiences and environmental exposures encountered during spaceflight. Telomere length (quantitative polymerase chain reaction and telomere fluorescence in situ hybridization) and telomerase activity (quantitative polymerase chain reaction -telomere repeat amplifice definitive mechanisms underlying such dramatic spaceflight-associated shifts in telomere length remain unclear, improved maintenance of telomere length has important implications for aging science and improving healthspan for those on Earth, as well. Large randomized controlled trials that evaluate the effects of negative-pressure wound therapy with instillation of a topical solution and dwell time (NPWTi-d) are lacking. There is a need to synthesize existing data across multiple studies to provide a more precise estimate of the clinical effects of NPWTi-d. A systematic literature review and a meta-analysis of comparative studies were performed to determine the effects of NPWTi-d versus control therapy in the adjunctive management of complex wounds. Weighted standardized mean difference or odds ratios and 95% confidence intervals were calculated to pool study and control group results in each publication for analysis. Thirteen studies comprising 720 patients were included in the analysis. Significantly fewer surgical debridements were performed in NPWTi-d patients versus control patients (P = 0.01). Wounds in the NPWTi-d group were ready for closure faster than control wounds (P = 0.03). The odds of reducing bacterial count from baseline in the NPWTi-d group was 4.4 times greater than control group wounds (P = 0.003), and percent reduction of bacterial count in NPWTi-d wounds was evident in all studies that captured that endpoint. There was a significantly shorter length of therapy in NPWTi-d patients versus control patients (P = 0.03). Wounds in NPWTi-d group were 2.39 times more likely to close than control group wounds (P = 0.01). Length of hospital stay was not significantly reduced for NPWTi-d patients compared with that for control patients (P = 0.06). Results of this meta-analysis show a positive effect with use of NPWTi-d in various wound types. Results of this meta-analysis show a positive effect with use of NPWTi-d in various wound types. The addition of topical fluid instillation, a programmable "dwell" time and a novel foam-wound interface to the established wound healing benefits of negative-pressure wound therapy (NPWT) works synergistically to benefit patients with complex wounds. https://www.selleckchem.com/ALK.html This engineering breakthrough for wound care has been termed NPWT with instillation and dwell (NPWTi-d), and the new foam dressings are reticulated open cell foam dressings specifically designed for use with NPWTi-d. This combined technology has shown promise in chronic, complex wounds and has potential for the management of sacral and ischial pressure wounds. A qualitative comprehensive review was performed analyzing articles from PubMed and Medline that reported on the use of NPWTi-d in sacral or ischial pressure ulcers. Case series and case reports were predominant, and results of cases specific to sacral and ischial pressure wounds were extracted from larger studies and summarized for presentation. Compared with conventional NPWT alone, NPWTi-d has been shown to help irrigate the wound, remove fibrinous debris, and promote granulation tissue formation. This is associated with a decreased number of operative debridements and decreased hospital length of stay. This technology is rapidly demonstrating expanded utilization in hospitalized patients with chronic sacral and ischial pressure ulcers. When used correctly, NPWTi-d serves as an effective "bridge to defined endpoint" whether that is a flap reconstruction, skin grafting, or discharge home with a stable chronic wound and simplified wound care.
