Abstract
Acral melanoma (AM) is the most common histologic subtype of melanoma in dark-skinned patients and is associated with a worse prognosis and a high mortality rate, largely due to the inconspicuous nature of early-stage lesions, which can lead to late diagnosis. Because of the overlapping clinical and histopathological features of AM with other forms of cutaneous melanomas, early detection of AM requires a multidisciplinary approach that integrates various diagnostic modalities, including clinical examination, dermoscopy, histopathology, molecular testing, radiological imaging, and blood tests. While surgery is the preferred method of treatment for AM, other therapeutic options may be employed based on the stage and underlying etiology of the disease. Immune checkpoint inhibitors, molecular targeted therapy, radiotherapy, chemotherapy, and oncolytic virotherapy represent promising advanced treatment options for AM. In this review, we provide an overview of the latest advancements in diagnostic and therapeutic methods for AM, highlighting the importance of early detection and the prompt, individualized management of this challenging disease.

Abstract
Although there is a higher incidence of melanoma among non-Hispanic White individuals, melanoma is diagnosed at more advanced stages and associated with worse survival rates among individuals with skin of color (SOC). The proportions of melanoma subtypes differ across racial groups, with acral lentiginous melanoma and mucosal melanoma representing higher proportions of melanoma diagnoses in individuals with SOC compared to White individuals. The recognition of distinct differences in anatomic locations and dermatoscopic patterns may facilitate the appropriate differentiation of physiologic from pathologic pigmentation. The first article of this continuing medical education series will focus on the epidemiology and clinical presentation of melanoma in individuals with SOC, with the aim of improving early diagnoses and clinical outcomes.

Clinical Analysis of the Renal Protective Effect of GLP-1 on Diabetic Patients Based on Edge Detection. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:6504006.

Abstract
With the rapid development of IoT technology, it is a new trend to combine edge computing with smart medicine in order to better develop modern medicine, avoid the crisis of information “sibling,” and meet the requirements of timeliness and computational performance of the massive data generated by edge devices. However, edge computing is somewhat open and prone to security risks, so the security and privacy protection of edge computing systems for smart healthcare is receiving increasing attention. The two groups were compared before and after treatment for blood glucose, blood lipids, blood pressure, renal function, serum advanced glycosylation end products (AGEs) and cyclic adenosine monophosphate (cAMP), serum oxidative stress indicators, and levels of cAMP/PKA signalling pathway-related proteins in peripheral blood mononuclear cells. The results of this study show that the reduction of AGEs, the improvement of oxidative stress, and the regulation of the cAMP/PKA signalling pathway may be associated with a protective effect against early DKD. By introducing the edge computing system and its architecture for smart healthcare, we describe the security risks encountered by smart healthcare in edge computing, introduce the solutions proposed by some scholars to address the security risks, and finally summarize the security protection framework and discuss the specific solutions for security and privacy protection under this framework, which will provide some help for the credible research of smart healthcare edge computing.

Abstract
Melanomas only account for 4% of all dermatologic cancers yet are responsible for 80% of deaths. Notably, melanomas of the hand and foot have a worse prognosis when compared with melanomas of other anatomic regions. Likely this is due to intrinsic biologic characteristics, delayed diagnosis, difficult surgical excision due to delicate anatomy, and lack of definitive diagnostic and therapeutic guidelines. The most common locations of melanoma of the hand, in order of decreasing frequency, are subungual area, dorsal surface, and palmar surface. The most common locations of melanoma of the foot are the plantar surface, dorsal surface, and subungual area, in decreasing frequency. Diagnosis of melanoma of the hand and foot can be difficult because the traditional "ABCDE" (asymmetric shape, border, color, diameter, evolution) rules do not apply. Newer acronyms have been proposed in literature including "CUBED" (colored, uncertain, bleeding, enlarged, delayed) and "ABC rule for Subungual Melanoma." Once diagnosed, treatment is primarily surgical excision and reconstruction. The goal for the surgeon is to maintain the function and anatomy of the hand or foot.

Abstract
Acral lentiginous melanoma is a histological subtype of cutaneous melanoma that occurs in the glabrous skin of the palms, soles and the nail unit. Although in some countries, particularly in Latin America, Africa and Asia, it represents the most frequently diagnosed subtype of the disease, it only represents a small proportion of melanoma cases in European-descent populations, which is partially why it has not been studied to the same extent as other forms of melanoma. As a result, its unique genomic drivers remain comparatively poorly explored, as well as its causes, with current evidence supporting a UV-independent path to tumorigenesis. In this review, we discuss current knowledge of the aetiology and diagnostic criteria of acral lentiginous melanoma, as well as its epidemiological and histopathological characteristics. We also describe what is known about the genomic landscape of this disease and review the available biological models to explore potential therapeutic targets.

Abstract
Acral lentiginous melanoma is a distinct subtype of melanoma on acral skin. Patient presentation at later stages and delayed diagnosis by physicians contribute to a worse associated prognosis and survival rate. Despite our progress in understanding the key features of this disease, the diagnosis of early-stage acral melanoma is still challenging. It is essential to integrate clinical, dermoscopic, and histologic findings in the diagnosis of acral lentiginous melanoma. In addition, molecular studies can be helpful. In this review, we have summarized our current understanding of this disease entity from articles that were published between 1969 and 2018. We have outlined clinical and dermoscopic features as well as pathologic and molecular findings regarding acral melanoma and have presented an algorithm for diagnosis. Understanding and integrating these characteristics may assist clinicians in the early detection of acral melanomas.

Improvement of ursolic and oleanolic acids' antitumor activity by complexation with hydrophilic cyclodextrins. Biomed Pharmacother 2016; 83:1095-1104. [PMID: 27551755 DOI: 10.1016/j.biopha.2016.08.030] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Revised: 08/01/2016] [Accepted: 08/09/2016] [Indexed: 12/13/2022] Open
Abstract
Ursolic and oleanolic acids have been brought into the spotlight of research due to their chemopreventive, anti-inflammatory and immunomodulatory properties. The most important disadvantage of ursolic and oleanolic acids is their weak water solubility which limits their bioavailability. Pentacyclic triterpenes can form inclusion complexes with different types of cyclodextrins which provide the hydrophilic matrix requested for the molecular dispersion of drugs in order to become more water soluble. The aim of the current study is the complexation of ursolic and oleanolic acids with hydrophilic cyclodextrins in order to achieve an improvement of their pharmacological effect. After the virtual screening of the binding affinities between ursolic and oleanolic acids and various cyclodextrins, 2-hydroxypropyl-β-cyclodextrin and 2-hydroxypropil-γ-cyclodextrin were selected as host-molecules for the inclusion complexation. Using the scanning electron microscopy, differential scanning calorimetry and X-ray diffraction the formation of real inclusion complexes between ursolic and oleanolic acids and the two cyclodextrins was confirmed. The anti-proliferative potential of the complexes was tested in vitro on several melanoma cell lines, using the pure compounds as reference. The complexes exhibited higher in vitro anti-proliferative activity as compared to the pure compounds; this improvement was significant for ursolic acid complexes, the highest activity being reported for the 2-hydroxypropil-γ-cyclodextrin complex. Weaker results were recorded for the oleanolic acid complexes where 2-hydroxypropyl-β-cyclodextrin proved to be the most fitted inclusion partner. The entrapment of the two active compounds inside ramified hydrophilic cyclodextrins proved to be a suitable option to increase their anti-proliferative activity.

Abstract
The incidence of cutaneous melanoma is rising faster than that of almost any other cancer in the United States. Acral lentiginous melanoma is a subtype of melanoma that involves the palms, soles, and nail beds. Although it is one of the rarer types of melanoma, it has a poorer prognosis than other more common subtypes. We describe a case of plantar acral melanoma in a 66-year-old woman that was initially misdiagnosed as a traumatic foot ulcer. We highlight this case to emphasize the importance of close observation and biopsy of ulcerative lesions of the foot that have atypical features or are refractory to standard treatment.

Abstract
BACKGROUND Although dermatology, as a medical subject, has been a facet of the training and education of podiatrists for many years, it is, arguably, only in recent years that the speciality of podiatric dermatology has emerged within the profession. Some indication of this gradual development may be identified through a content analysis of the podiatric literature in the UK, spanning a 21 year timeframe. METHOD 6 key professional journals were selected for content analysis in order to provide a picture of the emergence and development of podiatric dermatology over a period extending from 1989 to 2010. Both syntactical and thematic unitization were deployed in the analysis, revealing both manifest and latent content. Categories were devised using a prior coding, a codebook produced to define relevant concepts and category characteristics, and the coding scheme subject to an assessment of reliability. RESULTS 1611 units appeared in the 6 journals across a 21 year timeframe. 88% (n = 1417) occurred in one journal (Podiatry Now and its predecessors). Modal categories within all journals included course adverts (n = 673), commercial adverts (n = 562) and articles by podiatrists (n = 133). There was an overall rise from 40 per annum in 1989, to over 100 in 2010. A wider range of dermatological topics were addressed, ranging from fungal nail infections to melanoma. CONCLUSIONS It is evident from this analysis that there has been an increasing focus on dermatology as a topic within the main podiatric journals in the UK over the last 21 years, primarily reflecting a rise in commercial advertising and an increase in academic dermatology related publications. Whilst earlier publications tended to focus on warts and fungal infections, more recent publications address a broader spectrum of topics. Changes in prescribing rights may be relevant to these findings, as may the enhanced professional and regulatory body requirements on continuing professional development.
