In this paper, the equations-of-motion method, which has been successfully applied to the prediction of electronic excitation energies, is used to derive a physically clear and computationally tractable theory of molecular electron affinities. The contributions to the calculated electron affinities made by the ion-neutral correlation energy difference and by the Hartree-Fock energy change can be computed separately in this theory. In addition, the change in the correlation energy of the parent molecule's electrons, which is caused by adding an ``extra'' electron, can be quantitatively assessed. The physical content of this theory is discussed in considerable detail, and a connection is made with the many-body Green Function theory. The technique is shown to have important advantages over the variational wavefunction approach, the most attractive feature being the small size of the matrices occurring in computational applications.

OLTPs can be challenging to treat. Arthroscopic treatment can lead to improved outcomes. However, the higher incidence of poor outcomes in our series may indicate less predictability in the treatment of OLTPs and that outcomes may not be equivalent to previous reported studies on OLTPs or osteochondral lesions of the talus.

The treatment of osteochondral lesions of the talus remains a challenge to the foot and ankle surgeon. Arthroscopic debridement and drilling will often provide satisfactory results. However, larger lesions and uncontained lesions are often associated with inferior functional outcomes and may require a more extensive initial procedure.

A search of the literature suggests that normal scapular rest position is neither agreed upon nor entirely described. A~~thoritic-s differ in their anatomical representation (1 ,.5,8,9, 1 1-1 4.17) and written description (9,ll-13) of normal scapular rest position. Kendall et a1 (12) make the distinction that normal scapular rest position is influenced by hand dominance, with the dominant hand having the lower scapula. They, as well as Netter (14). describe the medial borders of the scapulae as being essentially parallel, with Kendall et al (12) further describing the distance between these medial borders as being 7.62-1 0.16 cm (.%4 inches). Hoppenfeld (1 1) suggests that the posterior midline of the body lies midway between the scapulae and that the medial borders are 5.08 cm (2 inches) from the spinous processes. Gray (9) and H o p penfeld (1 1) each describe the superior angle of the scapula at the level of the second rib and the inferior angle of the scapula at the level of the seventh rib. Hoppenfeld (1 1) further adds that the root of the scapular spine (ie., the medial end of the spine of the scapula along its medial border) is at the level of the spinous

BACKGROUND: Lack of healthcare access to due to physician shortages is a significant driver of telemedicine expansion in rural areas. Telemedicine is effective for management of chronic conditions such as diabetes but its effectiveness in primary care settings is unknown. OBJECTIVE: To evaluate differences in diabetes care before and after implementation of a longitudinal virtual primary care program. DESIGN: Propensity score-matched cohort study utilizing difference-in-differences analysis. PARTICIPANTS: Patients with diabetes who received care at VA primary care clinics between January 2018 and December 2019 where the Virtual Integrated Multisite Patient Aligned Care Teams (V-IMPACT) program was implemented. EXPOSURE: Patient participation in at least one V-IMPACT visit while usual care patients did not participate in V-IMPACT. MAIN MEASURES: The primary outcome was change in hemoglobin A1C (HbA1C) and secondary outcomes included change in the proportion of patients meeting diabetes quality indicators: blood pressure control, statin use, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACEi/ARB) use, and annual microalbuminuria testing. KEY RESULTS: Our propensity-matched cohort included 9010 patients split evenly between those who participated in V-IMPACT and those who remained in usual in-person care. Among individuals with diabetes who participated in V-IMPACT, the change in mean HbA1C was − 0.055% (95% CI − 0.088 to − 0.022%) while those in usual care had a − 0.047% (95% CI − 0.080 to − 0.014%) change before and after program implementation. We observed a 5.1% (95% CI 2.4 to 7.7%) absolute increase in the proportion prescribed statins in the V-IMPACT group, a 5.3% (95% CI 2.5 to 8.2%) increase prescribed ACE/ARBs, and a 4.6% (95% 1.7 to 7.5%) increase in completed yearly microalbuminuria testing. V-IMPACT was not associated with a significant difference in the proportion with controlled blood pressure at < 140/90 or < 130/90 mmHg thresholds. CONCLUSIONS: Quality of diabetes care delivered by a longitudinal virtual primary care model was similar if not better than traditional in-person care.
