Secondary syphilis presenting as pseudolymphoma of the skin.

Secondary syphilis most commonly presents with a papulosquamous eruption that involves the palms, soles, and mucous membranes. The papulonodular variant has only been described 11 times in the literature. We describe a case of papulonodular secondary syphilis presenting as an atypical lymphoid hyperplasia suggestive of cutaneous lymphoma

Mechanisms of Polymer-Templated Nanoparticle Synthesis: Contrasting ZnS and Au

We combine solution small-angle X-ray scattering (SAXS) and high-resolution analytical transmission electron microscopy (ATEM) to gain a full mechanistic understanding of substructure formation in nanoparticles templated by block copolymer reverse micelles, specifically poly­(styrene)-<i>block</i>-poly­(2-vinylpyridine). We report a novel substructure for micelle-templated ZnS nanoparticles, in which small crystallites (∼4 nm) exist within a larger (∼20 nm) amorphous organic–inorganic hybrid matrix. The formation of this complex structure is explained via SAXS measurements that characterize <i>in situ</i> for the first time the intermediate state of the metal-loaded micelle core: Zn²⁺ ions are distributed throughout the micelle core, which solidifies as a unit on sulfidation. The nanoparticle size is thus determined by the radius of the metal-loaded core, rather than the quantity of available metal ions. This mechanism leads to particle size counterintuitively decreasing with increasing metal content, based on the modified interactions of the metal-complexed monomers in direct contrast to gold nanoparticles templated by the same polymer

Seminar on Adjustment and its Problems in Southern Iowa

This publication includes seminar papers presented and discussed by staff members of Iowa State University during the winter quarter of 1959. The seminar was sponsored by the Center for Agricultural and Economic Adjustment and met for two hours per week over a period of nearly three months. The seminar was organized to include a group of about 70 members designated by the committee listed below. The formal seminar group discus sed each paper after its presentation. The papers were revised in line with these discussions by the seminar group and recommendations by the seminar committee.</p

National survey of indigenous primary healthcare capacity and delivery models in Canada: the TransFORmation of IndiGEnous PrimAry HEAlthcare delivery (FORGE AHEAD) community profile survey

Background: There is a significant deficiency of national health information for Indigenous peoples in Canada. This manuscript describes the Community Profile Survey (CPS), a community-based, national-level survey designed to identify and describe existing healthcare delivery, funding models, and diabetes specific infrastructure and programs in Indigenous communities. Methods: The CPS was developed collaboratively through FORGE AHEAD and the First Nations and Inuit Health Branch of Health Canada. Regional and federal engagement and partnerships were built with Indigenous organizations to establish regionally-tailored distribution of the 8-page CPS to 440 First Nations communities. Results were collected (one survey per community) and reported in strata by region, with descriptive analyses performed on all variables. Results were shared with participating communities and regional/federal partners through tailored reports. Results: A total of 84 communities completed the survey (19% response rate). The majority of communities had a health centre/office to provide service to their patients with diabetes, with limited on-reserve hospitals for ambulatory or case-sensitive conditions. Few healthcare specialists were located on-site, with patients frequently travelling off-site (> 40 km) for diabetes-related complications. The majority of healthcare professionals on-site were Health Directors, Community Health Nurses, and Home Care Nurses. Many communities had a diabetes registry but few reported a diabetes surveillance system. Regional variation in healthcare services, diabetes programs, and funding models were noted, with most communities engaging in some type of innovative strategy to improve care for patients with diabetes. Conclusions: The CPS is the first community-based, national-level survey of its kind in Canada. Although the response rate was low, the CPS was distributed and successfully administered across a broad range of First Nations communities, and future considerations would benefit from a governance structure and leadership that strengthens community engagement, and a longitudinal research approach to increase the representativeness of the data. This type of information is important for communities and regions to inform decision making (maintain successes, and identify areas for improvement), strengthen health service delivery and infrastructure, increase accessibility to healthcare personnel, and allocate funding and/or resources to build capacity and foster a proactive chronic disease prevention and management approach for Indigenous communities across Canada.
