Abstract
Animals face many natural challenges, and humans have added to this burden by applying potentially harmful herbicides and unintentionally introducing competitors. We examine the recently introduced Velarifictorus micado Japanese burrowing cricket which shares the same microhabitat and mating season as the native Gryllus pennsylvanicus field cricket. In this study, we assess the combined effects of Roundup (glyphosate-based herbicide) and a lipopolysaccharide (LPS) immune challenge on both crickets. In both species, an immune challenge reduced the numbers of eggs that the female laid; however, this effect was much larger in G. pennsylvanicus. Conversely, Roundup caused both species to increase egg production, potentially representing a terminal investment strategy. When exposed to both an immune challenge and herbicide, G. pennsylvanicus fecundity was harmed more than V. micado fecundity. Furthermore, V. micado females laid significantly more eggs than G. pennsylvanicus, suggesting that introduced V. micado may have a competitive edge in fecundity over native G. pennsylvanicus. LPS and Roundup each had differing effects on male G. pennsylvanicus and V. micado calling effort. Overall, introduced male V. micado spent significantly more time calling than native G. pennsylvanicus, which could potentially facilitate the spread of this introduced species. Despite the population-level spread of introduced V. micado, in our study, this species did not outperform native G. pennsylvanicus in tolerating immune and chemical challenge. Although V. micado appears to possess traits that make this introduced species successful in colonizing new habitats, it may be less successful in traits that would allow it to outcompete a native species.

Breast Implant Illness: Surgical, Autoimmune, and Breast Reconstruction Associations. SURGERIES 2022.

Abstract
Breast implant illness refers to a combination of different symptoms related to breast implant surgery, including fatigue, brain fog, and arthralgias. This malaise occurs after cosmetic and reconstructive breast surgeries, although it has not been proven to be a disease. Even recent studies have reported concluding statements of the etiology, diagnosis, and treatment as unclear and widely unknown. Therefore, this review aimed to determine the associations between the manifestations of breast implant illness in surgery and breast reconstruction, as well as the autoimmune responses involved. Complications associated with breast implants include breast pain, capsular contracture, infections, as well as other manifestations specific to breast reconstruction. Moreover, patients with implants may present with new-onset systemic sclerosis, Sjögren’s syndrome, and connective tissue diseases. However, the incidence of capsular contracture has steadily decreased with each generation of implants, particularly since the development of textured implants, as well as with the use of antibiotics and antiseptic pocket irrigation. However, the incidence of anaplastic large cell lymphoma has increased with the use of textured implants. Remarkably, the autoimmune response to these implants remains unclear. Therefore, close follow-up, careful observation of any symptom presentation, and evidence-based treatment decisions are necessary for patients with breast implants.
