A People’s History of Leisure Studies : Old Knowledge, New Knowledge and The Philadelphia Negro as a Foundational Text

There is a great realization that a professor teaching an introductory or philosophical foundations course in the field of leisure studies comes to, if that professor may not be from the dominant culture of most Western societies. This realization is as stark as their numerical presence in their respective departments. Why are the philosophical foundations of the field devoid of the experiences, voices, and perspectives populations of color, or even more broadly, the populations of the global majority? And, why is there an absence of historical discussions on the field’s role in perpetrating or condoning activities that hindered or constrained populations of color full access, enjoyment, and articulation of leisure? As we move forward in the field more globally, thinking and discussing the new and progressive ways that we can conceive the sociology of leisure, it is imperative that we rethink our philosophical foundations in reconciliation of the potential harm it may have caused (and may continue to harm) and the actual good it can invoke in assisting the myriad of scholars who are pushing more progressive efforts for a critical leisure paradigm (Spracklen, Lashua, Sharpe and Swain, 2017). The objectives of this manuscript are: 1) to briefly categorize the research in the field on Race and ethnicity; 2) to outline the key canonical texts of the field; 3) to consider and reconceptualize a racially and ethnically inclusive foundation for the field utilizing The Philadelphia Negro: A Social Study as an example; and, 4) to identify some of the specific areas that this change and inclusion would impact or realign the field’s history

Physiology and Pathophysiology of Wound Healing in Diabetes

Wound healing is a dynamic process comprising of overlapping phases of hemostasis, inflammation, proliferation, and remodeling that involve multiple cell types. This highly organized and coordinated series of processes result in the restoration of tissue integrity. Deregulation in any of these processes leads to a delayed or nonhealing phenotype as seen in diabetic foot ulcers (DFUs). The functions and cell-to-cell communication between different cell types contributing to wound healing (keratinocytes, fibroblasts, endothelial cells, neutrophils, and macrophages) and their deregulation in chronic nonhealing ulcers are discussed in detail. The balance of signaling factors, including growth factors and gene expression regulators such as microRNA, and their spatiotemporal control is indispensable for successful wound healing, while their dysregulation contributes to pathophysiology of DFUs. Additional factors that contribute to the delayed healing seen in diabetes include macro- and microvascular, neuropathic, immune functions, and microbiome abnormalities. Novel therapeutic approaches including cell therapy, stem cells, and micrografting that provide perspective on how to efficiently treat patients with DFUs are also discussed
