Self-Assessment of Health Professionals’ Cultural Competence:Knowledge, Skills, and Mental Health Concepts for Optimal Health Care

Current research often refers to cultural competence to improve health care delivery. In addition, it focuses on the cultural uniqueness of each health service user for optimal personalized care. This study aimed to collect self-assessment data from health professionals regarding their cultural competence and to identify their development needs. A mixed methods design was adopted using the Cultural Competence Self-assessment Checklist of the Central Vancouver Island Multicultural Society. This was translated into Greek, validated, and then shared with health professionals in Cyprus. Subsequently, a semi-structured interview guide was designed and utilized. This was structured in exactly the same question categories as the questionnaire. Data collection took place between October 2021 and May 2022, and convenience sampling was used to recruit 499 health scientists in Cyprus. The sample comprised doctors, nurses, psychologists, midwives, social workers, and physiotherapists. Subsequently, 62 interviews were conducted with participants from the same specialties. The results showed that (compared to other health professionals) nurses and psychologists are more sensitive to issues of cultural competence. It would appear that the more socially oriented sciences had better-prepared healthcare staff to manage diversity in context. However, there is a gap between knowledge and skills when comparing doctors to nurses; they seem to be more skilled and willing to intervene actively in cases of racist behavior or problem-solving. In conclusion, participants identified the importance of their cultural competence; they also realized the importance of optimal planning of personalized health care. There is a significant need for continuous and specialized cultural competence training for all health professions

Translational assessment of a DATA-functionalized FAP inhibitor with facile 68Ga-labeling at room temperature.

PURPOSE The present study aims at evaluating the preclinical and the clinical performance of [68Ga]Ga-DATA5m.SA.FAPi, which has the advantage to be labeled with gallium-68 at room temperature. METHODS [68Ga]Ga-DATA5m.SA.FAPi was assessed in vitro on FAP-expressing stromal cells, followed by biodistribution and in vivo imaging on prostate and glioblastoma xenografts. Moreover, the clinical assessment of [68Ga]Ga-DATA5m.SA.FAPi was conducted on six patients with prostate cancer, aiming on investigating, biodistribution, biokinetics, and determining tumor uptake. RESULTS [68Ga]Ga-DATA5m.SA.FAPi is quantitatively prepared in an instant kit-type version at room temperature. It demonstrated high stability in human serum, affinity for FAP in the low nanomolar range, and high internalization rate when associated with CAFs. Biodistribution and PET studies in prostate and glioblastoma xenografts revealed high and specific tumor uptake. Elimination of the radiotracer mainly occurred through the urinary tract. The clinical data are in accordance with the preclinical data concerning the organ receiving the highest absorbed dose (urinary bladder wall, heart wall, spleen, and kidneys). Different to the small-animal data, uptake of [68Ga]Ga-DATA5m.SA.FAPi in tumor lesions is rapid and stable and tumor-to-organ and tumor-to-blood uptake ratios are high. CONCLUSION The radiochemical, preclinical, and clinical data obtained in this study strongly support further development of [68Ga]Ga-DATA5m.SA.FAPi as a diagnostic tool for FAP imaging

Anxiety and Depression in Patients with Permanent Atrial Fibrillation: Prevalence and Associated Factors

Atrial fibrillation (AF) is an important public health problem that is increasing at an alarming rate, worldwide. The most common type is permanent AF followed by the paroxysmal and persistent AF. Purpose. This study was aimed at exploring anxiety and depression and the associated factors in patients with permanent AF. Materials and Methods. The sample of the study included 170 AF patients. Data collection was performed by the method of interview using the “Hospital Anxiety and Depression Scale” (HADS) to assess anxiety and depression and a questionnaire including patients’ characteristics. Results. 70% of the participants were men, and 32.4% were above 70 years old. Furthermore, 34.9% of the patients had high levels of anxiety, and 20.2% had high levels of depression. Anxiety levels were statistically significantly associated with gender p=0.022, age p=0.022, educational level p=0.025, years having the disease p=0.005, and relations with nursing staff p=0.040. Depression levels were statistically significantly associated with age p=0.037, degree of information of the state of health p<0.001, years having the disease p<0.001, and relations with medical staff p=0.041. Conclusions. Patients’ characteristics are associated with anxiety and depression and need to be evaluated when treating this frequently encountered arrhythmia

PET Molecular Targets and Near-Infrared Fluorescence Imaging of Atherosclerosis

PURPOSE OF REVIEW: With this review, we aim to summarize the role of positron emission tomography (PET) and near-infrared fluorescence imaging (NIRF) in the detection of atherosclerosis. RECENT FINDINGS: (18)F-FDG is an established measure of increased macrophage activity. However, due to its low specificity, new radiotracers have emerged for more specific detection of vascular inflammation and other high-risk plaque features such as microcalcification and neovascularization. Novel NIRF probes are engineered to sense endothelial damage as an early sign of plaque erosion as well as oxidized low-density lipoprotein (oxLDL) as a prime target for atherosclerosis. Integrated NIRF/OCT (optical coherence tomography) catheters enable to detect stent-associated microthrombi. Novel radiotracers can improve specificity of PET for imaging atherosclerosis. Advanced NIRF probes show promise for future application in human. Intravascular NIRF might play a prominent role in the detection of stent-induced vascular injury

Radiochemistry and Preclinical PET Imaging of 68Ga-Desferrioxamine Radiotracers Targeting Prostate-Specific Membrane Antigen

Radiotracers incorporating the urea-based Glu-NH-C(O)-NH-Lys group have gained prominence due to their role in targeting prostate-specific membrane antigen (PSMA)—a clinical biomarker of prostate cancer. Here, the synthesis, radiolabeling, and in vitro and in vivo characterization of two 68Ga-radiolabeled Glu-NH-C(O)-NH-Lys radiotracers conjugated to the desferrioxamine B (DFO) chelate were evaluated. Two linker groups based on amide bond and thiourea coupling chemistries were employed to develop 68Ga-DFO-Nsucc-PSMA (68Ga-4) and 68Ga-DFO-pNCS-Bn-PSMA (68Ga-7), respectively. Radiosynthesis proceeded quantitatively at room temperature with high radiochemical yields, chemical/radiochemical purities, and specific activities. Pharmacokinetic profiles of 68Ga-4 and 68Ga-7 were assessed using positron-emission tomography (PET) in mice bearing subcutaneous LNCaP tumors. Data were compared to the current clinical benchmark radiotracer 68Ga-HBED-CC-PSMA (68Ga-1) (HBED ¼ N,N0-Bis(2-hydroxy-5-(ethylene-beta-carboxy)benzyl)ethylenediamine N,N0-diacetic acid). Results indicated that the target binding affinity, protein association, blood pool and background organ clearance properties, and uptake in PSMApositive lesions are strongly dependent on the nature of the chelate, the linker, and the spacer groups. Protein dissociation constants (Kd values) were found to be predictive of pharmacokinetics in vivo. Compared to 68Ga-1, 68Ga-4 and 68Ga-7 resulted in decreased tumor uptake but enhanced blood pool clearance and reduced residence time in the kidney. The study highlights the importance of maximizing protein binding affinity during radiotracer optimization
