Currently, food insecurity is a lack of access to enough food for a healthy life that impacts approximately 40 million Americans and 821 million people worldwide. These statistics are expected to rise as a result of the COVID-19 pandemic drastically. Studies show that healthcare and nursing curricula are currently deficient in providing education to help healthcare providers combat food security and provide patient education. The purpose of this article is to discuss a curricular framework that can be implemented in both nursing and healthcare curricula to offer appropriate training for food insecurity assessment, care, and patient education., (© 2020 Organization for Associate Degree Nursing.

Vibrational spectroscopic data were collected on the salt [C5H6N]2[Cl3FeOFeCl3] . C5H5N, which has previously been structurally characterized by X-ray crystallography. The modes associated with the oxo bridge were identified by experiments on the 18O-containing species. Spectra for the mu-16O complex contain Raman bands at 870, 458, and 203 cm-1 that shift to 826, 440, and 198 cm-1 in the mu-18O complex. These are respectively assigned to the asymmetric, symmetric, and angle deformations of the bent Fe-O-Fe moiety. A normal mode vibration analysis based on a simple valence force field for the Fe-O-Fe portion of the molecule provides surprisingly good agreement with these experimental frequencies and their assignments. The vibrational data for this simple inorganic complex confirm the assignment of a resonance Raman band around 500 cm-1 in the oxygen-carrying protein hemerythrin and enzyme ribonucleotide reductase as the symmetric stretch of an oxo bridge between two iron(III) centers.

With extra precautions to remove dissolved oxygen, reduction of aquomethemerythrin with dithionite occurs with a stoichiometry very close to 1.0. The aquosemimethemerythrin so produced combines with N3- ion almost on a 1:1 basis per monomer. Resonance Raman spectra of azidosemimethemerythrin differ from those of azidomethemerythrin in the position of the Fe-N stretching frequency and in the absence of a feature corresponding to a mu-oxo bridge, but in both complexes the internal azide stretch occurs at the same frequency and the substitution of isotopically unsymmetrical 15N14N-2 leads to a splitting of the Fe-N band. These observations provide some insight into the structural features of the binuclear functional site.
