To investigate whether modifications of prostate-specific membrane antigen (PSMA)-targeted radiolabeled urea-based inhibitors could reduce salivary gland uptake and thus improve tumor-to-salivary gland ratios, several analogs of a high affinity PSMA ligand were synthesized and evaluated in in vitro and in vivo studies.
 
  Binding motifs were synthesized 'on-resin' or, when not practicable, in solution. Peptide chain elongations were performed according to optimized standard protocols via solid-phase peptide synthesis. In vitro experiments were performed using PSMA
  LNCaP cells. In vivo studies as well as μSPECT/CT scans were conducted with male LNCaP tumor xenograft-bearing CB17-SCID mice.
 
  PSMA ligands with A) modifications within the central Zn
  -binding unit, B) proinhibitor motifs and C) substituents & bioisosteres of the P1'-γ-carboxylic acid were synthesized and evaluated. Modifications within the central Zn
  -binding unit of PSMA-10 (Glu-urea-Glu) provided three compounds. Thereof, only 
  Lu-carbased PSMA inhibitor [
  Lu]Lu-PSMA-10. Although two derivatives (3 and 11) were found to exhibit high affinities towards LNCaP cells, tumor uptake at 24 h p.i. was considerably low, while uptake in salivary glands remained unaffected. Optimization of the established animal model should be envisaged to enable a clear identification of PSMA-targeting radioligands with improved tumor-to-salivary gland ratios in future studies.
 The investigated compounds could not compete with the in vivo characteristics of the EuE-based PSMA inhibitor [177Lu]Lu-PSMA-10.

Surveys were collected at baseline, 6-months, and 12-months. Semi-structured interviews and focus groups were conducted during site visits, and a stakeholder roundtable was facilitated to address broader themes. Data were analyzed using qualitative thematic analysis. Practices reported successful engagement with the framework and actively participated in planning and advancing BHI operations. Greater success was observed in practices with existing on-site BHI services, identified champions for BHI, early and sustained training and involvement of providers and administrators, use of collaborative agreements with external behavioral health providers, and capacity to successfully receive reimbursements for BHI services. Advancing health information technologies was a challenge across sites. Financing and policy factors were viewed as critically important to advance integration efforts. The pilot of a continuum framework offers lessons for primary care practices and policymakers to advance integrated BH care.A disproportionate number of people with mental illness are involved in critical police encounters resulting in arrest and/or excessive use of force. In response, many jurisdictions have implemented Crisis Intervention Team training. This mixed method study used survey and focus group interview data to investigate Crisis Intervention Teams in rural communities in a Northeastern state in the U.S. Findings indicate that unique situational realities prevent optimal effectiveness of Crisis Intervention Teams in rural jurisdictions. Three themes emerged as clear barriers to effectiveness (a) time and money; (b) buy-in and support for Crisis Intervention Teams; and (c) systemic barriers to adequate care. Rural-specific impediments affect each aspect and member of Crisis Intervention Teams in rural jurisdictions. Efforts to develop a specialized police response training program for rural jurisdictions should be developed and examined.
  The purpose of our study was to determine the usability of lung ultrasonography (LUS) in the diagnosis of COVID-19, and to match the morphological features of lesions detected on computed tomography (CT) with the findings observed on LUS.
 
  Sixty patients with COVID-19 were included in this prospective study. Patients were examined by radiology and anesthesia clinic specialists for a visual CT score. A LUS 12-zone ultrasonography protocol was applied by the investigator blinded to the CT and PCR test results. The characteristics of abnormal findings and the relationship of lesions to the pleura and the distance to the pleura were investigated.
 
  Forty-five males and 25 females evaluated within the scope of the study had an average age of 61.2 ± 15.3years. The total CT score was calculated as 14.3 ± 5.3, and the LUS score was found to be 19.9 ± 7.6. There was a statistically significant positive correlation between the measured LUS and CT scores (r = 0.857, p < 0.001). The mean distance of these lesions to the pleura was 5.2 ± 1.76cm. LUS findings in 51 areas corresponded to non-pleural lesions on CT. There was a negative correlation between the measured distance to the pleura and the LUS scores (p < 0.001, r = - 0.708).
 
  The results of this study showed that the correlation between CT and LUS findings may be used in the diagnosis of COVID-19 pneumonia, although there are some limitations. ClinicalTrials.gov identifier NCT04719234.

  Immune checkpoint inhibitors promote the antitumor activity of T cells; however, there is a risk of side effects. The aim of this study was to characterize the computed tomography (CT) findings of one such side effect, anti-programmed cell death-1 antibody-related enterocolitis (αPD-1-EC).
 
  This single-institution retrospective study included 21 patients with αPD-1-EC who underwent CT between January 2015 and April 2020. Two board-certified radiologists independently evaluated the CT findings, including the pattern of intestinal wall enhancement, maximum bowel wall thickness, maximum appendiceal diameter, and involvement of enterocolitis in each intestinal segment. Symptoms and their severity were also investigated.
 
  Pancolitis and skip lesions involving both the rectosigmoid colon and the cecum were found in 9 patients each (42.9%). The rectum was the most frequently involved lesion (18/21, 85.7%), and appendiceal involvement was found in 11 patients (52.4%). The most frequent wall enhancement pattern was the gray pattern (i.
