While cognitive-behavioral therapy for hoarding disorder (HD) has resulted in significant reductions in symptoms, most individuals continue to have significant hoarding symptoms following treatment. This investigation sought to extend the literature on the behavioral treatments for hoarding by examining (1) group cognitive rehabilitation and exposure/sorting therapy (CREST) and (2) group exposure therapy (ET) for hoarding. Participants in both studies reported significant decreases in hoarding symptom severity from baseline to post-treatment on all primary outcome measures using mixed-effects linear regression models with the intent to treat sample. Participants who received group CREST reported statistically significant reductions in anxiety, depression, and overall severity at post-treatment, while participants who received group ET did not. Results provide preliminary evidence for both group CREST and group ET as effective treatments for hoarding disorder. 相似文献

Cardiovascular imaging has significantly evolved since the turn of the century. Progress in the last two decades has been marked by advances in every modality used to image the heart, including echocardiography, cardiac magnetic resonance, cardiac CT and nuclear cardiology. There has also been a dramatic increase in hybrid and fusion modalities that leverage the unique capabilities of two imaging techniques simultaneously, as well as the incorporation of artificial intelligence and machine learning into the clinical workflow. These advances in non-invasive cardiac imaging have guided patient management and improved clinical outcomes. The technological developments of the past 20 years have also given rise to new imaging subspecialities and increased the demand for dedicated cardiac imagers who are cross-trained in multiple modalities. This state-of-the-art review summarizes the evolution of multimodality cardiac imaging in the 21st century and highlights opportunities for future innovation. 相似文献

ObjectiveTo examine the effect of oral dextrose gel and oral feedings on newborns’ blood sugar homeostasis in the first day of life in an effort to decrease transfers to the NICU.DesignEvidence-based practice project.Setting/Local ProblemObstetric service at a large hospital in northeast Ohio with approximately 5,300 births annually. Neonates who experienced hypoglycemia were often transferred to the NICU for management if treatment measures failed, thereby increasing the cost of care and separating mothers from their newborns. During 2018, there were 54 neonates transferred to the NICU for hypoglycemia.ParticipantsPediatricians, neonatologists, neonatal nurse practitioners, clinical nurse specialists, managers, educators, and registered nurses.Intervention/MeasurementsAn interdisciplinary task force created a nurse-driven protocol and associated order set and also created and provided interdisciplinary education to all involved caregivers using a multimodal approach. Neonates’ charts were audited for the time period of April 2019 to April 2020 to evaluate participants’ compliance with the prescribed practice changes.ResultsThe number of neonates who qualified for blood glucose testing per the new protocol totaled 1,369. Of these, 188 (14%) met criteria for and were treated with 40% dextrose gel. Treatment with 40% dextrose gel was unsuccessful for 25 neonates, who were then transferred to the NICU. This is 29 fewer than were transferred in 2018.ConclusionThe use of oral dextrose gel and oral feedings was associated with a decrease in the number of newborns transferred to a higher level of care for treatment of hypoglycemia. 相似文献
