Resource Management Challenges in Rural Dermatological Care: A Mapping Review.

Skin cancer prevalence in the United States is rapidly on the rise, particularly in rural communities where individuals are subjected to heavy sunlight exposure through occupations such as agricultural work and construction. These geographic regions are often lacking in dermatologic specialty care, thus increasing the disease burden of skin conditions in primary care settings. Access barriers to specialized dermatology care are exacerbated by prolonged wait times to schedule an appointment, travel demands, and a relative paucity of dermatology providers in rural areas as compared to urban areas.

Investigation of silver salt metathesis: preparation of cationic germanium(II) and Tin(II) complexes, and silver adducts containing unsupported silver-germanium and silver-tin bonds.

Syntheses of halide derivatives of germanium(II) and tin(II) aminotroponiminate (ATI) complexes and their silver salt metathesis reactions have been investigated. The treatment of GeCl(2) x (1,4-dioxane), SnCl(2), or SnI(2) with [(n-Pr)(2)ATI]Li in a 1:1 molar ratio affords the corresponding germanium(II) or tin(II) halide complex [(n-Pr)(2)ATI]MX (where [(n-Pr)(2)ATI](-) = N-(n-propyl)-2-(n-propylamino)troponiminate; M = Ge or Sn; X = Cl or I). As usually expected, [(n-Pr)(2)ATI]GeCl and [(n-Pr)(2)ATI]SnCl undergo rapid metathesis with CF(3)SO(3)Ag, leading to trifluoromethanesulfonate salts, [[(n-Pr)(2)ATI]Ge][SO(3)CF(3)] and [[(n-Pr)(2)ATI]Sn][SO(3)CF(3)], and silver chloride.
