Background: Perceived personal control (PPC) represents the belief that a person can alter his/her own situation or state. Higher PPC has been associated with increased health-related quality of life and helps facilitate healthy behavioral changes. We investigated whether disclosure of coronary heart disease (CHD) genetic risk influences PPC and genetic counseling satisfaction (GCS) in the myocardial infarction genes (MI-GENES) study, a randomized controlled trial of disclosing genetic risk of CHD. Methods: Participants (40-65 year-old, at intermediate 10-year CHD risk, and not on statins) were randomized to receive estimated 10-year risk of CHD based on their Framingham Risk Score (FRS) or FRS plus a 28 SNP genetic risk score (FRS*GRS). CHD risk was disclosed in each arm by a genetic counselor during a 30-minute scripted session that included a discussion of the impact of family history on CHD risk. For FRS*GRS participants, the genetic counselor also reviewed how their genetic risk score altered their FRS. Each participant then met with a physician to engage in shared-decision making regarding the need for statin therapy. Afterwards, study participants were asked to complete validated surveys to assess PPC and GCS. The 9-item PPC questionnaire was scored 0-9, with higher scores indicating greater control beliefs. The 5-item GCS questionnaire was scored 0-10, with greater scores indicating greater satisfaction with the disclosure session. Results: 207 patients (mean age 58.8±5 years, 46.7% males) were randomized to receive either FRS or FRS*GRS. Patients randomized to receive FRS*GRS had higher PPC compared to FRS although the absolute difference was small (8.85±0.77 vs. 8.54±1.31, P=0.016). Patients randomized to receive FRS*GRS also had a higher GCS score than FRS patients (9.08±2.67 vs. 8.3±3.67, P=0.050]. Conclusions: Disclosure of genetic risk for CHD did not adversely affect PPC or GCS. In fact, patients who received CHD genetic risk information had higher PPC and GCS. Our findings suggest that disclosure of CHD genetic risk is appreciated by patients and may empower them to improve health-related behaviors.

Antibiotic use is often the target of interventions in health care organizations that aim to decrease healthcare-associated infections (HAI) such as Clostridioides difficile (CDI); this is particularly important for fluoroquinolones (FQ), which are frequently used in critical care settings. In this study, using a multiple case study research approach, we conduct an in-depth analysis of an intervention aimed at limiting ICU prescriber access to FQ in two ICUs of two hospitals. The data collection and analysis were guided by a human factors engineering approach based on the SEIPS (Systems Engineering Initiative for Patient Safety) model and evidence-based implementation principles. Our results show some differences in the implementation of the FQ intervention between the two ICUs, such as level and method of FQ restriction, and training and communication with physicians and pharmacists. In both ICUs, several organizational learning mechanisms helped to quickly identify problems with the intervention and ensure that changes were made in a just-in-time manner (e.g. just-in-time training, removal of FQ in order set for pneumonia). Despite their organizational differences, both sites developed strategies to successfully implement the FQ intervention.

Background There is heterogeneity in the names and anatomical descriptions of regional anesthetic techniques. This may have adverse consequences on education, research, and implementation into clinical practice. We aimed to produce standardized nomenclature for abdominal wall, paraspinal, and chest wall regional anesthetic techniques. Methods We conducted an international consensus study involving experts using a three-round Delphi method to produce a list of names and corresponding descriptions of anatomical targets. After long-list formulation by a Steering Committee, the first and second rounds involved anonymous electronic voting and commenting, with the third round involving a virtual round table discussion aiming to achieve consensus on items that had yet to achieve it. Novel names were presented where required for anatomical clarity and harmonization. Strong consensus was defined as ≥75% agreement and weak consensus as 50% to 74% agreement. Results Sixty expert Collaborators participated in this study. After three rounds and clarification, harmonization, and introduction of novel nomenclature, strong consensus was achieved for the names of 16 block names and weak consensus for four names. For anatomical descriptions, strong consensus was achieved for 19 blocks and weak consensus was achieved for one approach. Several areas requiring further research were identified. Conclusions Harmonization and standardization of nomenclature may improve education, research, and ultimately patient care. We present the first international consensus on nomenclature and anatomical descriptions of blocks of the abdominal wall, chest wall, and paraspinal blocks. We recommend using the consensus results in academic and clinical practice.

Abstract Most patients with coronavirus disease 2019 (COVID-19) have mild to moderate illness not requiring hospitalization. However, no study has detailed the evolution of symptoms in the first month of illness. At our institution, we conducted remote (telephone and video) visits for all adult outpatients diagnosed with COVID-19 within 24 h of a positive nasopharyngeal polymerase chain test for SARS-CoV-2. We repeated regular video visits at 7, 14, and 28 days after the positive test, retrospectively reviewed the prospective data collected in the remote visits, and constructed a week by week profile of clinical illness, through week 4 of illness. We reviewed the courses of 458 symptomatic patients diagnosed between March 12, 2020, and June 22, 2020, and characterized their weekly courses. Common initial symptoms included fever, headache, cough, and chest pain, which frequently persisted through week 3 or longer. Upper respiratory or gastrointestinal symptoms were much shorter lived, present primarily in week 1. Anosmia/ageusia peaked in weeks 2 to 3. Emergency department visits were frequent, with 128 visits in the 423 patients who were not hospitalized and 48 visits among the 35 outpatients (7.6%) who were eventually hospitalized (2 subsequently died). By the fourth week, 28.9% said their illness had completely resolved. After the 4-week follow up, 20 (4.7%) of the 423 nonhospitalized patients had further medical evaluation and management for subacute or chronic COVID-19 symptoms. Mild to moderate outpatient COVID-19 is a prolonged illness, with evolving symptoms commonly lasting into the fourth week of illness.

Abstract Background/Objective: Changes in speech can be detected objectively before and during migraine attacks. The goal of this study was to interrogate whether speech changes can be detected in subjects with post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI) and whether there are within-subject changes in speech during headaches compared to the headache-free state. Methods: Using a series of speech elicitation tasks uploaded via a mobile application, PTH subjects and healthy controls (HC) provided speech samples once every three days, over a period of 12 weeks. The following speech parameters were assessed: vowel space area, vowel articulation precision, consonant articulation precision, average pitch, pitch variance, speaking rate and pause rate. Speech samples of subjects with PTH were compared to HC. To assess speech changes associated with PTH, speech samples of subjects during headache were compared to speech samples when subjects were headache-free. All analyses were conducted using a mixed-effect model design.Results: Longitudinal speech samples were collected from nineteen subjects with PTH (mean age=42.5, SD=13.7) who were an average of 14 days (SD=32.2) from their mTBI at the time of enrollment and thirty-one HC (mean age=38.7, SD=12.5). Regardless of headache presence or absence, PTH subjects had longer pause rates and reductions in vowel and consonant articulation precision relative to HC. On days when speech was collected during a headache, there were longer pause rates, slower sentence speaking rates and less precise consonant articulation compared to the speech production of HC. During headache, PTH subjects had slower speaking rates and altered vowel articulation compared to when they were headache-free. Conclusions: Compared to HC, subjects with acute PTH demonstrate altered speech as measured by objective features of speech production. For individuals with PTH, speech was altered during headache vs. when they were headache-free, suggesting that speech alterations were related to PTH and not solely due to the underlying mTBI.

Abstract PURPOSE: Ovarian cancer remains the most lethal gynecological malignancy in the United States even though there are a number of treatment options. For the newly diagnosed ovarian cancer patient, treatment is standard with the majority of patients receiving first-line platinum/taxol treatment following surgical debulking or as part of a neo-adjuvant treatment regimen. Standard response assessment to this chemotherapy combination depends on lengthy clinical follow-up of at least 6 months following the conclusion of the chemotherapy. This course is initially effective in 70-80% of patients, but 20-30% will relapse within the 6 months post-chemotherapy or not respond at all. Additionally, most of the initial responders will also relapse. Early prediction of the patients whose cancers do not respond could lead to earlier intervention with more effective therapy. RESULTS: To perform this prediction, we developed a test utilizing live tumor tissue and 3D cell culture to predict the response of ovarian cancer patients to standard platinum and taxol chemotherapy along with the standard agents used for relapse patients. To validate the assay, we performed a prospective trial involving 86 women with newly diagnosed ovarian cancer from whom live tumor tissue was recovered at surgical resection prior to chemotherapy. Of the 79 patients whose tissues yielded a successful assay result, 27 had sufficient clinical follow-up to determine the accuracy of the response predictions made by the assay. Assay response predictions were made within 7 days following surgery while clinical response was not determined until 6 months or more following the conclusion of first-line chemotherapy. Assay results predicted first-line chemotherapy response in 100% of clinical responders (19 of 19) and first-line chemotherapy non-response in 62.5% of clinical non-responders (5 of 8) as defined by CA-125 and radiographic surveillance. This response prediction was statistically significant by Fisher's Exact test, p < 0.001. The sensitivity of the assay was 86% while the specificity was 100%. When the assay results were examined in terms of progression free survival, 19 of 19 patients identified as responders by the assay remained progression free at least 6 months post-chemotherapy with 14 remaining progression free 10 or more months post-chemotherapy. In contrast, of the 8 assay non-responders, 3 were refractory with progression within 3 months of chemotherapy conclusion and 2 progressed less than 6 months post-chemotherapy with a mean progression free survival of 4.5 months. CONCLUSIONS: Our rapid, ex vivo, 3D cellular assay is capable of accurate patient specific response prediction of first-line combination therapy in newly diagnosed ovarian cancer patients and can serve as a prognostic indicator of progression free survival. This preliminary clinical validation shows the significant potential of this assay as a future tool in personalized cancer care for ovarian cancer patients.

AbstractBackgroundBamlanivimab and casirivimab-imdevimab are authorized for emergency use treatment of mild to moderate coronavirus disease 2019 (COVID-19) in patients at high risk for developing severe disease or hospitalization. Their safety and efficacy have not been specifically evaluated in solid organ transplant recipients.MethodsWe retrospectively reviewed solid organ transplant recipients who received monoclonal antibody infusion for COVID-19 at Mayo Clinic sites through January 23, 2021. Outcomes included emergency department visit, hospitalization, mortality, and allograft rejection.ResultsSeventy-three patients were treated, most commonly with bamlanivimab (75.3%). The median age was 59 years, 63% were male, and the median Charlson comorbidity index was 5. Transplant type included 41 kidney (56.2%), 13 liver (17.8%), 11 heart (15.1%), 4 kidney-pancreas (5.5%), 2 lung (2.7%), 1 heart-liver, and 1 pancreas. Eleven (15.1%) patients had an emergency department visit within 28 days of infusion, including 9 (12.3%) who were hospitalized for a median of 4 days. One patient required intensive care unit admission for a nonrespiratory complication. No patients required mechanical ventilation, died, or experienced rejection. Ten adverse events occurred, with 1 seeking medical evaluation. Hypertension was associated with hospital admission (P < .05), while other baseline characteristics were similar. The median time from symptom onset to antibody administration was 4 days in nonhospitalized patients compared with 6 days among hospitalized patients (P < .05).ConclusionsMonoclonal antibody treatment has favorable outcomes with minimal adverse effects in solid organ transplant recipients with mild to moderate COVID-19. Earlier administration of monoclonal antibody therapy appears to be more efficacious.

4069 Background: CCA is a rare cancer for which there are limited effective therapies. IDH1 mutations occur in ̃20% of intrahepatic CCAs, resulting in production of the oncometabolite D-2-hydroxyglutarate, which promotes oncogenesis. IVO (AG-120) is a first-in-class, oral, small-molecule inhibitor of mutant IDH1 (mIDH1). ClarIDHy aimed to demonstrate the efficacy of IVO vs PBO in pts with unresectable or metastatic m IDH1 CCA. The primary endpoint was met with significant improvement in progression-free survival (PFS) by independent radiology center (IRC) with IVO vs PBO (hazard ratio [HR] = 0.37, p < 0.0001). Objective response rate (ORR) and stable disease for IVO were 2.4% (3 partial responses) and 50.8% (n = 63) vs 0% and 27.9% (n = 17) for PBO. IVO pts experienced significantly less decline in physical and emotional functioning domains of quality of life at cycle 2 day 1 vs PBO pts (nominal p < 0.05). Methods: Pts with m IDH1 CCA were randomized 2:1 to IVO (500 mg PO QD) or matched PBO and stratified by prior systemic therapies (1 or 2). Key eligibility: unresectable or metastatic m IDH1 CCA based on central testing; ECOG PS 0–1; measurable disease (RECIST v1.1). Crossover from PBO to IVO was permitted at radiographic progression. Primary endpoint: PFS by IRC. Secondary endpoints included overall survival (OS; by intent-to-treat), ORR, PFS (by investigator), safety, and quality of life. The planned crossover-adjusted OS was derived using the rank-preserving structural failure time (RPSFT) model. Results: As of 31 May 2020, ̃780 pts were prescreened for an IDH1 mutation and 187 were randomized to IVO (n = 126) or PBO (n = 61); 13 remain on IVO. Median age 62 y; M/F 68/119; 91% intrahepatic CCA; 93% metastatic disease; 47% had 2 prior therapies. 70% of PBO pts crossed over to IVO. OS data were mature, with 79% OS events in IVO arm and 82% in PBO. Median OS (mOS) was 10.3 months for IVO and 7.5 months for PBO (HR = 0.79; 95% CI 0.56–1.12; one-sided p = 0.093). The RPSFT-adjusted mOS was 5.1 months for PBO (HR = 0.49; 95% CI 0.34–0.70; p < 0.0001). Common all-grade treatment emergent adverse events (TEAEs, ≥ 15%) in the IVO arm: nausea 41%, diarrhea 35%, fatigue 31%, cough 25%, abdominal pain 24%, decreased appetite 24%, ascites 23%, vomiting 23%, anemia 18%, and constipation 15%. Grade ≥ 3 TEAEs were reported in 50% of IVO pts vs 37% of PBO pts, with grade ≥ 3 treatment-related AEs in 7% of IVO pts vs 0% in PBO. 7% of IVO pts experienced an AE leading to treatment discontinuation vs 9% of PBO pts. There were no treatment-related deaths. Conclusions: IVO was well tolerated and resulted in a favorable OS trend vs PBO despite a high rate of crossover. These data – coupled with statistical improvement in PFS, supportive quality of life data, and favorable safety profile – demonstrate the clinical benefit of IVO in advanced m IDH1 CCA. Clinical trial information: NCT02989857.

The study aim was to test hypotheses informed by self-determination theory (SDT) regarding associations of adolescent motivators for weight loss and family feeding practices on understanding adolescent weight management and dietary behaviors. Adolescents (n = 71) with obesity were recruited from a large medical center in the Midwest USA and completed questionnaire assessments via an online survey. Results supported hypotheses that endorsement of health motivators for weight loss, conceptualized as autonomous (intrinsic) motivation, and positive family support would be associated with healthier weight management practices and dietary behaviors. Nuanced findings related to social- and self-esteem-related motivators for weight loss indicated a need for further understanding of these weight-loss motivators in the context of SDT. The current study findings highlight the importance of addressing motivational factors and family influences in research and practice related to promoting healthy dietary habits and weight management strategies among adolescents with obesity.
