Accelerated Resolution Therapy for Early Maladaptive Grief Study Protocol.

The objective of this manuscript is to present the protocol of a study aiming to test the effects of Accelerated Resolution Therapy® (ART) on pre-loss grief and prolonged grief among older adult family caregivers. This study also aims to better understand predictors of response to ART®, and cognitive processes that occur among grieving individuals following ART®. DESIGN: The study is a double-blinded, randomized clinical trial. SETTING: This study takes place at both inpatient and outpatient palliative care and hospice programs at two Mayo Clinic sites. PARTICIPANTS: Participants include older adult (≥ 60 years) immediate family members who are primary caregivers of someone with an advanced illness and life expectancy of less than 12 months. INTERVENTION: Participants are randomized to either the ART® intervention group or the attention control group. In the ART® intervention, caregivers engage in imaginal exposure, lateral eye movements, and imagery rescripting via 4 sessions lasting 1-1.5 hours each. The attention control group receives a standard social work intervention, including education, resources, and active listening, which is matched for time and attention. Both interventions will longitudinally follow caregivers from active caregiving into bereavement. OUTCOMES MEASURED: The primary outcomes of pre-loss grief and prolonged grief will be measured with the Pre-Loss Grief 12 item (PG-12-R) before the care recipient's death, and with the Prolonged Grief-13 (PG-13-R) afterwards.

Urinary Tract Infection and Neuropathic Bladder.

Urinary tract infections (UTIs) are the most common infection in patients with neurogenic bladder. Diagnosis is fraught with challenges since there is no globally accepted definition for UTI and symptoms can vary widely. Due to the increased risk of morbidity, it is important to have a thorough understanding of the risk of UTI, diagnostic criteria, and to treat aggressively when UTI is confirmed. Prevention of UTI is optimal but more studies are needed to identify the best methods to prevent UTIs in this population.

Multifiller-based polymer composites for shielding high energy ionising radiation.

Polydimethyl silicone rubber-based polymer composites filled with molybdenum and bismuth were fabricated using simple open mold cast technique. The physical and chemical structure and gamma shielding parameters like attenuation coefficient, half-value layer (HVL) thickness and relaxation length have been investigated for the said novel materials using X-ray diffraction (XRD), Fourier transform Infrared spectroscopy (FTIR) and gamma ray spectrometer. XRD study reveals the crystalline nature of the composites. It is evident from FTIR studies that there is no chemical interaction between the polymer matrix and filler particles. The results of attenuation studies reveal that the linear attenuation coefficient increases with addition of Bi and Mo and is found to be 0.653, 1.341 and 1.017, 1.793 and 0.102, 0.152 cm-1 for 1MMB and 2MMB polymer composites at 80, 356 and 662 keV gamma rays, respectively. The HVL thickness of the materials is found to be 1.06, 0.51 and 0.68, 0.38 and 6.73, 4.532 cm for 1MMB (20Mo + 10Bi phr) and 2MMB (40Mo + 20Bi phr) at these energies, respectively. The mass attenuation coefficient of the novel composites 1MMB and 2MMB is found to be higher than the conventional materials like lead and barite for 356 keV gamma rays. In addition, the material is found to be light weight and flexible enabling to be molded in required forms, thus being a substitute for the material lead that is known to be heavy and toxic by nature.

Modulation of a critical period for motor development in Drosophila by BK potassium channels.

Critical periods are windows of heightened plasticity occurring during neurodevelopment. Alterations in neural activity during these periods can cause long-lasting changes in the structure, connectivity, and intrinsic excitability of neurons, which may contribute to the pathology of neurodevelopmental disorders. However, endogenous regulators of critical periods remain poorly defined. Here, we study this issue using a fruit fly (Drosophila) model of an early-onset movement disorder caused by BK potassium channel gain of function (BK GOF). Deploying a genetic method to place robust expression of GOF BK channels under spatiotemporal control, we show that adult-stage neuronal expression of GOF BK channels minimally disrupts fly movement. In contrast, limiting neuronal expression of GOF BK channels to a short window during late neurodevelopment profoundly impairs locomotion and limb kinematics in resulting adult flies. During this critical period, BK GOF perturbs synaptic localization of the active zone protein Bruchpilot and reduces excitatory neurotransmission. Conversely, enhancing neural activity specifically during development rescues motor defects in BK GOF flies. Collectively, our results reveal a critical developmental period for limb control in Drosophila that is influenced by BK channels and suggest that BK GOF causes movement disorders by disrupting activity-dependent aspects of synaptic development.

Second Victim Experiences of Health Care Learners and the Influence of the Training Environment on Postevent Adaptation.

Objective: To investigate the experience of medical and graduate learners with second victim experience (SVE) after medical errors or adverse patient outcomes, including impact on training and identification of factors that shape their postevent recovery. Patients and Methods: The validated Second Victim Experience and Support Tool-Revised (SVEST-R), Physician Well-Being Index, and supplemental open-ended questions were administered to multidisciplinary health care learners between April 8, 2022, and May 30, 2022, across a large academic health institution. Open-ended responses were qualitatively analyzed for iterative themes related to impact of SVE on the training experience. Results: Of the 206 survey respondents, 144 answered at least 1 open-ended question, with 62.1% (n=91) reporting at least 1 SVE. Participants discussed a wide range of SVEs and indicated that their postevent response was influenced by their training environment. Lack of support from supervisors and staff exacerbated high stress situations. Some trainees felt blamed and unsupported after a traumatic experience. Others emphasized that positive training experiences and supportive supervisors helped them grow and regain confidence. Learners described postevent processing strategies helpful to their recovery. Some, however, felt disincentivized from seeking support. Conclusion: This multidisciplinary study of learners found that the training environment was influential in postevent recovery. Our findings support the need for the inclusion of education on SVEs and adaptive coping mechanisms as part of health care professional educational curriculums. Educators and health care staff may benefit from enhanced education on best practices to support trainees after stressful or traumatic patient events.

Scintigraphy of Gastrointestinal Motility: Best Practices in Assessment of Gastric and Bowel Transit in Adults.

Various radiologic examinations and other diagnostic tools exist for evaluating gastrointestinal diseases. When symptoms of gastrointestinal disease persist and no underlying anatomic or structural abnormality is identified, the diagnosis of functional gastrointestinal disorder is frequently applied. Given its physiologic and quantitative nature, scintigraphy often plays a central role in the diagnosis and treatment of patients with suspected functional gastrointestinal disorder. Most frequently, after functional gallbladder disease is excluded, gastric emptying scintigraphy (GES) is considered the next step in evaluating patients with suspected gastric motility disorder who present with upper gastrointestinal symptoms such as dyspepsia or bloating. GES is the standard modality for detecting delayed gastric emptying (gastroparesis) and the less commonly encountered clinical entity, gastric dumping syndrome. Additionally, GES can be used to assess abnormalities of intragastric distribution, suggesting specific disorders such as impaired fundal accommodation or antral dysfunction, as well as to evaluate gastric emptying of liquid. More recently, scintigraphic examinations for evaluating small bowel and large bowel transit have been developed and validated for routine diagnostic use. These can be performed individually or as part of a comprehensive whole-gut transit evaluation. Such scintigraphic examinations are of particular importance because clinical assessment of suspected functional gastrointestinal disorder frequently fails to accurately localize the site of disease, and those patients may have motility disorders involving multiple portions of the gastrointestinal tract. The authors comprehensively review the current practice of gastrointestinal transit scintigraphy, with diseases and best imaging practices illustrated by means of case review. ©RSNA, 2024 See the invited commentary by Maurer and Parkman in this issue.

Implementation of an Automated Antibiotic Time-out at a Comprehensive Cancer Center.

Background: Antimicrobial stewardship programs can optimize antimicrobial use and have been federally mandated in all hospitals. However, best stewardship practices in immunocompromised patients with cancer are not well established. Methods: An antimicrobial time out, in the form of an email, was sent to physicians caring for hospitalized patients reaching 5 days of therapy for targeted antimicrobials (daptomycin, linezolid, tigecycline, vancomycin, imipenem/cilastatin, meropenem) in a comprehensive cancer center. Physicians were to discontinue the antimicrobial if unnecessary or document a rationale for continuation. This is a quasi-experimental, interrupted time series analysis assessing antimicrobial use during the following times: period 1 (before time-out: January 2007-June 2010) and period 2 (after time-out: July 2010-March/2015). The primary antimicrobial consumption metric was mean duration of therapy. Days of therapy per 1000 patient-days were also assessed. Results: Implementation of the time-out was associated with a significant decrease in mean duration of therapy for the following antimicrobials; daptomycin: -0.89 days (95% confidence interval [CI], -1.38 to -.41); linezolid: -0.89 days (95% CI, -1.27 to -.52); meropenem: -0.97 days (95% CI, -1.39 to -.56); tigecycline: -1.41 days (95% CI, -2.19 to -.63); P < .001 for each comparison. Days of therapy/1000 patient-days decreased significantly for meropenem (-43.49; 95% CI, -58.61 to -28.37; P < .001), tigecycline (-35.47; 95% CI, -44.94 to -26.00; P < .001), and daptomycin (-9.47; 95% CI, -15.25 to -3.68; P = .002). Discussion: A passive day 5 time-out was associated with reduction in targeted antibiotic use in a cancer center and could potentially be successfully adopted to several settings and electronic health records.

A pilot study on the global practice of informed consent in paediatric dentistry.

Background: Conducting oral treatment early in the disease course, is encouraged for better health outcomes. Obtaining informed consent is an essential part of medical practice, protecting the legal rights of patients and guiding the ethical practice of medicine. In practice, consent means different things in different contexts. Silver Diamine Fluoride (SDF) and Silver Fluoride (SF) is becoming popular and cost effective methods to manage carious lesions, however, cause black discolouration of lesions treated. Obtaining informed consent and assent is crucial for any dental treatment-and has specific relevance with SDF/ SF treatments. Methods: The aim of this paper is to describe informed consent regulations for dental care in a selection of countries, focusing on children and patients with special health care needs. An online survey was shared with a convenience sample of dental professionals from 13 countries. The information was explored and the processes of consent were compared. Results: Findings suggest that there are variations in terms of informed consent for medical practice. In Tanzania, South Africa, India, Kenya, Malaysia and Brazil age is the determining factor for competence and the ability to give self-consent. In other countries, other factors are considered alongside age. For example, in Singapore, the United Kingdom, and the United States the principle of Gillick Competence is applied. Many countries' laws and regulations do not specify when a dentist may overrule general consent to act in the "best interest" of the patient. Conclusion: It is recommended that it is clarified globally when a dentist may act in the "best interest" of the patient, and that guidance is produced to indicate what constitutes a dental emergency. The insights gathered provide insights on international practice of obtaining informed consent and to identify areas for change, to more efficient and ethical treatment for children and patients with special needs. A larger follow up study is recommended to include more or all countries.

Preliminary Investigation Into the Effectiveness of Group webSTAIR for Trauma-exposed Veterans in Primary Care.

INTRODUCTION: A substantial number of trauma-exposed veterans seen in primary care report significant symptoms of PTSD and depression. While primary care mental health integration (PCMHI) providers have been successful in delivering brief mental health treatments in primary care, few studies have evaluated interventions that combine mobile health resources with PCMHI groups. This pilot study assessed the potential benefits of webSTAIR, a 10-module transdiagnostic treatment for trauma-exposed individuals, supported by 5 biweekly group sessions delivered via telehealth. The transdiagnostic and mobile health nature of the treatment, as well as the therapist and peer support provided through group sessions, may offer an innovative approach to increasing access to patient-centered and trauma-informed treatment in primary care settings. MATERIALS AND METHODS: Thirty-nine male and female veterans with trauma-related symptoms (i.e., PTSD and/or depression) participated in group webSTAIR. Mixed effects analyses were conducted to assess changes in PTSD and depression at pre-, mid-, and post-treatment. Baseline symptom severity was assessed as a predictor of module completion and group attendance. The project was part of a VHA quality improvement project, and IRB approval was waived by the affiliated university. RESULTS: Analyses revealed significant pre-to-post improvement in both PTSD and depression outcomes with a large effect size for PTSD (Hedges' gav = 0.88) and medium to large for depression (Hedges' gav = 0.73). Of participants who completed the baseline assessment, 90% began webSTAIR; of those, 71% completed the program. Baseline symptoms of PTSD and depression did not predict group attendance or module completion. CONCLUSIONS: Good outcomes and a satisfactory retention rate suggest that group webSTAIR may provide easily accessible, high-quality, and effective treatment for patients presenting with trauma-related problems without increasing therapist or system burdens. The results suggest the value of conducting a randomized controlled trial to test the effectiveness of group webSTAIR relative to PCMHI usual care or other evidence-based, disorder-specific (e.g., PTSD) treatments for trauma-exposed individuals in PCMHI.

Proposed revision of the American Association for Surgery of Trauma Renal Organ Injury Scale: Secondary analysis of the Multi-institutional Genitourinary Trauma Study.

BACKGROUND: This study updates the American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) for renal trauma using evidence-based criteria for bleeding control intervention. METHODS: This was a secondary analysis of a multicenter retrospective study including patients with high-grade renal trauma from seven level 1 trauma centers from 2013 to 2018. All eligible patients were assigned new renal trauma grades based on revised criteria. The primary outcome used to measure injury severity was intervention for renal bleeding. Secondary outcomes included intervention for urinary extravasation, units of packed red blood cells transfused within 24 hours, and mortality. To test the revised grading system, we performed mixed-effect logistic regression adjusted for multiple baseline demographic and trauma covariates. We determined the area under the curve (AUC) to assess accuracy of predicting bleeding interventions from the revised grading system and compared this to 2018 AAST OIS. RESULTS: Based on the 2018 OIS grading system, we included 549 patients with AAST grades III to V injuries and computed tomography scans (III, 52% [n = 284]; IV, 45% [n = 249]; and V, 3% [n = 16]). Among these patients, 89% experienced blunt injury (n = 491), and 12% (n = 64) underwent intervention for bleeding. After applying the revised grading criteria, 60% (n = 329) of patients were downgraded, and 4% (n = 23) were upgraded; 2.8% (n = 7) downgraded from grade V to IV, and 69.5% (n = 173) downgraded from grade IV to III. The revised renal trauma grading system demonstrated improved predictive ability for bleeding interventions (2018 AUC, 0.805; revised AUC, 0.883; p = 0.001) and number of units of packed red blood cells transfused. When we removed urinary injury from the revised system, there was no difference in its predictive ability for renal hemorrhage intervention. CONCLUSION: A revised renal trauma grading system better delineates the need for hemostatic interventions than the current AAST OIS renal trauma grading system. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level III.
