ABSTRACT

When people interact, their behavior tends to become synchronized, a mutual coordination process that fosters short-term adaptations, like increased affiliation, and long-term adaptations, like increased bonding. This paper addresses for the first time how such short-term and long-term adaptivity induced by synchronization can be modeled computationally by a second-order multi-adaptive neural agent model. It addresses movement, affect and verbal modalities and both intrapersonal synchrony and interpersonal synchrony. The behavior of the introduced neural agent model was evaluated in a simulation paradigm with different stimuli and communication-enabling conditions. Moreover, in this paper, mathematical analysis is also addressed for adaptive network models and their positioning within the landscape of adaptive dynamical systems. The first type of analysis addressed shows that any smooth adaptive dynamical system has a canonical representation by a self-modeling network. This implies theoretically that the self-modeling network format is widely applicable, which also has been found in many practical applications using this approach. Furthermore, stationary point and equilibrium analysis was addressed and applied to the introduced self-modeling network model. It was used to obtain verification of the model providing evidence that the implemented model is correct with respect to its design specifications.

ABSTRACT

BACKGROUND: Pericoronary adipose tissue (PCAT) and Coronary Artery Disease Reporting and Data System (CAD-RADS) category had prognostic values for major adverse cardiovascular events (MACEs). However, little is known about the difference between CAD-RADS and PCAT computed tomography (CT) attenuation for predicting MACEs. This study was to compare the prognostic value of PCAT and CAD-RADS for MACEs in patients with acute chest pain.

METHODS: Between January 2010 and December 2021, all consecutive emergency patients with acute chest pain referred for coronary computed tomography angiography were enrolled in this retrospective study. MACEs included unstable angina requiring hospitalization, coronary revascularization, nonfatal myocardial infarction, and all-cause death. Patients’ clinical characteristics, CAD-RADS, and PCAT CT attenuation were used to evaluate risk factors of MACEs using multivariable Cox regression analysis.

RESULTS: A total of 1313 patients were evaluated (mean age, 57.13±12.57 years; 782 men). During a median follow-up of 38 months, 142 of the 1313 patients (10.81%) experienced MACEs. Multivariable Cox regression analysis showed that CAD-RADS categories 2, 3, 4, 5 (hazard ratio range, 2.286-8.325; all P<0.005) and right coronary artery PCAT CT attenuation (hazard ratio, 1.033; P=0.006) were independent predictors of MACEs after adjusting for clinical risk factors. The C statistics revealed that CAD-RADS improved risk stratification compared with PCAT CT alone (C-index, 0.760 versus 0.712; P=0.036). However, the benefit of right coronary artery PCAT CT attenuation combined with CAD-RADS was not significant compared with CAD-RADS alone (0.777 versus 0.760; P=0.129).

CONCLUSIONS: Right coronary artery PCAT CT attenuation and CAD-RADS were independent predictors of MACEs. However, no incremental prognostic value of right coronary artery PCAT CT attenuation beyond CAD-RADS was detected for MACEs in patients with acute chest pain.

ABSTRACT

BACKGROUND AND OBJECTIVES: Canadian blood donations declined during the start of the COVID-19 pandemic. Conversely, vaccine demand outpaced supply during the initial stages of the COVID-19 vaccine rollout in Canada. This study investigates public perceptions regarding vaccine-incentivized blood donation, among COVID-19 and future pandemics, in Canada.

MATERIALS AND METHODS: A 19-question survey was developed and distributed in person and online to Canadians during the third wave of the COVID-19 pandemic. Participants were asked questions about demographics, blood donation eligibility, previous donations and sentiments towards vaccine-incentivized blood donation. Data were analysed using descriptive statistics.

RESULTS: In total, 787 respondents completed the survey with representation from all sexes, ages, races, locations of residence and work employment. Overall, 176 (22%) participants self-identified as working or living in healthcare settings, 511 (65%) were currently able to donate blood products, 247 (31%) previously donated blood and 48 (6%) donated blood during the COVID-19 pandemic. With the exception of ineligible blood donors, many Canadians, particularly previous blood donors, were agreeable with this incentivization proposal. Many participants claimed they would donate blood products for vaccines during COVID-19 and future pandemics but raised concerns about the equitableness of such approach.

CONCLUSION: Vaccine-incentivized blood donation was viewed positively by many Canadians in our study. Future research must investigate the equity and feasibility of this strategy. In the interim, further strategies should be explored to encourage blood donation in Canada.

ABSTRACT

OBJECTIVE: To identify characteristics of antifungal prospective audit and feedback (PAF) and to compare rates of PAF recommendation and acceptance between antifungal and antibiotic agents.

DESIGN: Retrospective cohort study of antifungal and antibiotic audits by a children’s hospital antimicrobial stewardship program (ASP) from November 1, 2020, to October 31, 2022.

METHODS: Antimicrobial audit data were retrieved from the ASP data warehouse. We characterized antifungal PAF using descriptive statistics. We then compared the overall rates of PAF recommendation and recommendation acceptance between antifungals and antibiotics. We also compared the differences in antifungal and antibiotic PAF recommendation and acceptance rates across various factors, including infectious problem, medical service, and recommendation type.

RESULTS: Of 10,402 antimicrobial audits identified during the study period, 8,599 (83%) were for antibiotics and 1,803 (17%) were for antifungals. The highest antifungal recommendation rates were for liposomal amphotericin B, antifungals used for sepsis or respiratory tract infection, and antifungals prescribed in the cardiovascular intensive care unit. The rate of PAF recommendation was higher for antibiotics than for antifungals (29% vs 21%; P < .001); however, the rates of recommendation acceptance were similar. Recommendations to discontinue or for medication monitoring were more common for antifungals.

CONCLUSIONS: Our analysis of antifungal PAF identified key opportunities to improve antifungal use, including the optimized use of specific agents and targeted use by certain medical services. Moreover, antifungal PAF, despite identifying fewer recommendations compared to antibiotic PAF, were associated with similarly high rates of acceptance, highlighting a promising opportunity for antifungal stewardship.

ABSTRACT

INTRODUCTION: Regular blood glucose/A1c, blood pressure (BP), and cholesterol (ABC) testing is important for diabetes management. It is unknown whether pandemic-related disruptions in medical care were negatively associated with ABC testing among US adults with diagnosed diabetes.

RESEARCH DESIGN AND METHODS: A cross-sectional analysis was conducted among adults ≥18 years with diagnosed diabetes who participated in the 2019 or 2021 National Health Interview Survey (n=3355 and n=3127, respectively). Adults with diabetes self-reported sociodemographic and diabetes-related characteristics, ABC testing in the past year, and delays or not getting medical care due to the pandemic (2021 only). Descriptive statistics were used to determine differences in ABC testing in 2019 vs 2021. Logistic regression models were used to assess the association between delays or not getting medical care due to the pandemic and ABC testing, adjusting for sociodemographic characteristics, diabetes duration, and diabetes medication use.

RESULTS: Overall, the prevalence of having a blood glucose/A1c or a BP test in the past year was high (>90%) but it was significantly lower in 2021 compared with 2019 (A1c: 94.2% vs 96.8%, p<0.001; BP: 96.8% vs 98.4%, p=0.002, respectively). Cholesterol testing remained stable (93.0% in 2021 vs 94.5% in 2019, p=0.053). In logistic regression analysis, after full adjustment, adults who reported delaying or not getting medical care when needed due to the pandemic were 50% less likely to get an ABC test in the past year compared with those who promptly received medical care (A1c: adjusted OR (aOR)=0.44, 95% CI 0.29-0.68; BP: aOR=0.48, 95% CI 0.27-0.85; cholesterol: aOR=0.48, 95% CI 0.31-0.75).

CONCLUSIONS: Disruptions in medical care during the pandemic were associated with a decrease in ABC testing. Future research is needed to assess whether blood glucose/A1c and BP testing returns to prepandemic levels and if reductions in these tests result in excess diabetes-related complications.

ABSTRACT

Little is known regarding the shared genetic influences underlying the observed phenotypic association between chronotype and breast cancer in women. Leveraging summary statistics from the hitherto largest genome-wide association study conducted in each trait, we investigated the genetic correlation, pleiotropic loci, and causal relationship of chronotype with overall breast cancer, and with its subtypes defined by the status of oestrogen receptor. We identified a negative genomic correlation between chronotype and overall breast cancer ( $r_g$ = -0.06, p = 3.00 × 10^-4 ), consistent across oestrogen receptor-positive ( $r_g$ = -0.05, p = 3.30 × 10^-3 ) and oestrogen receptor-negative subtypes ( $r_g$ = -0.05, p = 1.11 × 10^-2 ). Five specific genomic regions were further identified as contributing a significant local genetic correlation. Cross-trait meta-analysis identified 78 loci shared between chronotype and breast cancer, of which 23 were novel. Transcriptome-wide association study revealed 13 shared genes, targeting tissues of the nervous, cardiovascular, digestive, and exocrine/endocrine systems. Mendelian randomisation demonstrated a significantly reduced risk of overall breast cancer (odds ratio 0.89, 95% confidence interval 0.83-0.94; p = 1.30 × 10^-4 ) for genetically predicted morning chronotype. No reverse causality was found. Our work demonstrates an intrinsic link underlying chronotype and breast cancer, which may provide clues to inform management of sleep habits to improve female health.

ABSTRACT

BACKGROUND: Melphalan, which is poorly soluble at room temperature, is widely used for the treatment of retinoblastoma by selective ophthalmic artery infusion. Evomela, a propylene glycol-free formulation of melphalan with improved solubility and stability, has recently been used as an alternative.To compare the safety and efficacy of Evomela with standard-formulation melphalan (SFM) in the treatment of retinoblastoma by selective ophthalmic artery infusion.

METHODS: We performed a retrospective case-control study of patients with retinoblastoma undergoing selective ophthalmic artery infusion with SFM or Evomela at a single institution. Cycle-specific percent tumor regression (CSPTR) was estimated by comparing photos obtained during pretreatment examination under anesthesia (EUA) with those obtained during post-treatment EUA 3-4 weeks later. CSPTR, ocular salvage rates, complication rates, operation times (unadjusted and adjusted for difficulty of ophthalmic artery catheterization), and intraprocedural dose expiration rates were compared between Evomela- and SFM-treated groups. Univariate and multivariate analyses were performed.

RESULTS: Ninety-seven operations (melphalan: 45; Evomela: 52) for 23 patients with 27 retinoblastomas were studied. The ocular salvage rate was 79% in the SFM-treated group and 69% in the Evomela-treated group. Multivariate regression controlling for tumor grade, patient age, and treatment history revealed no significant differences in ocular salvage rate, CSPTR, complication rates, or operation times. Although the dose expiration rate was higher for the SFM-treated group, the difference was not statistically significant. Notably, there were no ocular or cerebral ischemic complications.

CONCLUSION: Evomela has non-inferior safety and efficacy relative to SFM when used for the treatment of retinoblastoma by selective ophthalmic artery infusion.

ABSTRACT

AIM: This study aimed to determine the effect of an attachment-based intervention program (ABIP) on attachment, prenatal expectation and stress levels in pregnant women.

METHODS: This randomized controlled study was conducted in the pregnant outpatient clinics of a public hospital in Turkey. The study sample consisted of a total of 154 pregnant women (77 experimental, 77 control) at 28-38 weeks of gestation. The ABIP was applied to the pregnant women in the experimental group for 5-7 days. The ABIP included five interventions: (1) perceiving/counting fetal movements; (2) music therapy; (3) preparation for the baby; (4) writing notes/letters to the baby; and (5) watching images of the fetus/pregnancy.

RESULTS: After the ABIP, pregnant women in the experimental group had higher prenatal maternal attachment and prenatal positive expectation mean scores than those in the control group, and the difference between them was statistically significant in favor of those in the experimental group (P < .001). In addition, pregnant women in the experimental group had lower prenatal negative expectation and prenatal distress mean scores than those in the control group, and the difference between them was statistically significant in favor of those in the experimental group (P < .001).

CONCLUSIONS: The results of this study suggest that ABIP is a unique and pioneering program to increase maternal-antenatal attachment and prenatal positive expectations and reducing prenatal negative expectations and distress through diverse interventions. However, further research is required to assess the effectiveness of ABIP on maternal-fetal attachment, prenatal maternal expectations, and prenatal distress.

ABSTRACT

OBJECTIVE: The objective of the study was to assess the level of pharmacy student well-being during the first 2 years of their didactic education utilizing the Well-being Index (WBI) and 5 Gears assessment.

METHODS: WBI and 5 Gears data were tracked monthly for first- and second-year students enrolled at the Medical University of South Carolina College of Pharmacy from September 2019 to March 2022. Data were collected through monthly RedCap surveys, then de-identified and separated into 4 study cohorts (A-D). Data were analyzed using descriptive statistics.

RESULTS: Responses from 279 students were evaluated. WBI ratings showed variance across the first and second professional years of the program. Students also reported fluctuations in WBI throughout academic years, most often correlating with major events (scheduled breaks, COVID-19 pandemic). Similarly, the 5 Gears assessments results also changed throughout the study period, including variance within and between each academic year.

CONCLUSION: Incorporating well-being assessments into the co-curriculum has allowed us to identify when students are struggling with their well-being, provide tools and resources to help enhance their well-being, and opportunities to discuss struggles with their peers. Colleges of Pharmacy must incorporate holistic approaches to address all aspects of well-being, including consideration of how the curriculum is impacting the student experience as well as institutional approaches to well-being.

ABSTRACT

BACKGROUND: Little is known regarding the risk of cerebrovascular events (CVE) in patients with heart failure and severe secondary mitral regurgitation treated with transcatheter edge-to-edge repair (TEER).

OBJECTIVES: The study sought to examine the incidence, predictors, timing, and prognostic impact of CVE (stroke or transient ischemic attack) in the COAPT (Cardiovascular Outcomes Assessment of the Mitraclip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation) trial.

METHODS: A total of 614 patients with heart failure and severe secondary mitral regurgitation were randomized to TEER plus guideline-directed medical therapy (GDMT) vs GDMT alone.

RESULTS: At 4-year follow-up, 50 CVEs occurred in 48 (7.8%) of the 614 total patients enrolled in the COAPT trial; Kaplan-Meier event rates were 12.3% in the TEER group and 10.2 in the GDMT alone group (P = 0.91). Within 30 days of randomization, CVE occurred in 2 (0.7%) patients randomized to TEER and 0% randomized to GDMT (P = 0.15). Baseline renal dysfunction and diabetes were independently associated with increased risk of CVE, while baseline anticoagulation was associated with a reduction of CVE. A significant interaction was present between treatment group and anticoagulation such that TEER compared with GDMT alone was associated with a reduced risk of CVE among patients with anticoagulation (adjusted HR: 0.24; 95% CI: 0.08-0.73) compared with an increased risk of CVE in patients without anticoagulation (adjusted HR: 2.27; 95% CI: 1.08-4.81; P_interaction = 0.001). CVE was an independent predictor of death within 30 days after the event (HR: 14.37; 95% CI: 7.61, 27.14; P < 0.0001).

CONCLUSIONS: In the COAPT trial, the 4-year rate of CVE was similar after TEER or GDMT alone. CVE was strongly associated with mortality. Whether anticoagulation is effective at reducing CVE risk after TEER warrants further study.
