2. Selecting Scaling Indicators in Structural Equation Models (SEMs).

Author

Bollen, Kenneth A., Lilly, Adam G., and Luo, Lan

Abstract

It is common practice for psychologists to specify models with latent variables to represent concepts that are difficult to directly measure. Each latent variable needs a scale, and the most popular method of scaling as well as the default in most structural equation modeling (SEM) software uses a scaling or reference indicator. Much of the time, the choice of which indicator to use for this purpose receives little attention, and many analysts use the first indicator without considering whether there are better choices. When all indicators of the latent variable have essentially the same properties, then the choice matters less. But when this is not true, we could benefit from scaling indicator guidelines. Our article first demonstrates why latent variables need a scale. We then propose a set of criteria and accompanying diagnostic tools that can assist researchers in making informed decisions about scaling indicators. The criteria for a good scaling indicator include high face validity, high correlation with the latent variable, factor complexity of one, no correlated errors, no direct effects with other indicators, a minimal number of significant overidentification equation tests and modification indices, and invariance across groups and time. We demonstrate these criteria and diagnostics using two empirical examples and provide guidance on navigating conflicting results among criteria. Structural equation or factor analysis models include latent variables. These are variables that are part of our theories but that we cannot measure without error. Latent variables require a scale or metric. Typically, we assign the latent variable a scale that is similar to one of its indicators. This article provides guidance on how to choose scaling indicators for latent variables. It also includes diagnostics to help assess the quality of scaling indicators. [ABSTRACT FROM AUTHOR]

Abstract

Standardized consensus-based radiological reports for shoulder instability may improve clinical quality, reduce heterogeneity, and reduce workload. Therefore, the aim of this study was to determine important elements for the x-ray, magnetic resonance imaging (MRI) arthrography (MRA), and computed tomography (CT) report, the extent of variability, and important MRI views and settings.

Abstract

To identify trends in the reporting of intraoperative transesophageal echocardiographic (TEE) data in the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) and the Adult Cardiac Anesthesiology (ACA) module by period, practice type, and geographic distribution, and to elucidate ongoing areas for practice improvement. A retrospective study. STS ACSD. Procedures reported in the STS ACSD between July 2017 and December 2021 in participating programs in the United States. None Intraoperative TEE is reported for 73% of all procedures in ACSD. Although the intraoperative TEE data reporting rate increased from 2017 to 2021 for isolated coronary artery bypass graft surgery, it remained low at 62.2%. The reporting of relevant echocardiographic variables across a wide range of procedures has steadily increased over the study period but also remained low. The reporting in the ACA module is high for most variables and across all anesthesia care models; however, the overall contribution of the ACA module to the ACSD remains low. This progress report suggests a continued need to raise awareness regarding current practices of reporting intraoperative TEE in the ACSD and the ACA, and highlights opportunities for improving reporting and data abstraction.

6. Red Blood Cell Transfusion and Pulmonary Complications: The Society of Thoracic Surgeons Adult Cardiac Surgery Database Analysis.

Author

Raphael, Jacob, Chae, Alice, Feng, Xiaoke, Shotwell, Matthew S., Mazzeffi, Michael A., Bollen, Bruce A., Pfeil, Douglas, Feduska, Eric, Shah, Ashish S., and Kertai, Miklos D.

Abstract

Intraoperative packed red blood cell (PRBC) transfusion during cardiac surgery is associated with increased postoperative morbidity and mortality; however, data on the association between PRBC transfusion and postoperative pulmonary complications (PPCs) are somewhat conflicting. Using The Society of Thoracic Surgeons Adult Cardiac Surgery Database, we sought to determine whether intraoperative PRBC transfusion was associated with PPCs as well as with longer intensive care unit (ICU) stay after isolated coronary artery bypass grafting (CABG) surgery. A registry-based cohort study was performed on 751,893 patients with isolated CABG between January 1, 2015, to December 31, 2019. Using propensity score–weighted regression analysis, we analyzed the effect of intraoperative PRBC on the incidence of PPCs (hospital-acquired pneumonia [HAP], mechanical ventilation for >24 hours, or reintubation), ICU length of stay, and ICU readmission. Transfusion of 1, 2, 3, and ≥4 units of PRBCs was associated with increased odds for HAP (odds ratios [ORs], 1.24 [95% CI, 1.21-1.26], 1.28 [95% CI, 1.26-1.32], 1.36 [95% CI, 1.33-1.39], 1.31 [95% CI, 1.28-1.34]), reintubation (ORs, 1.23 [95% CI, 1.21-1.25], 1.38 [95% CI, 1.35-1.40], 1.57 [95% CI, 1.55-1.60], 1.70 [95% CI, 1.67-1.73]), prolonged ventilation (ORs, 1.34 [95% CI, 1.33-1.36], 1.56 [95% CI, 1.53-1.58], 1.97 [95% CI, 1.94-2.00], 2.27 [95% CI, 2.24-2.30]), initial ICU length of stay (mean difference in hours, 6.79 [95% CI, 6.00-7.58], 9.55 [95% CI, 8.71-10.38], 17.26 [95% CI, 16.38-18.15], 22.14 [95% CI, 21.22-23.06]), readmission to ICU (ORs, 1.14 [95% CI, 1.12-1.64], 1.15 [95% CI, 1.12-1.17], 1.15 [95% CI, 1.13-1.18], 1.32 [95% CI, 1.29-1.35]), and additional ICU length of stay (mean difference in hours, 0.55 [95% CI, 0.18-0.92], 0.38 [95% CI, 0.00-0.77], 1.02 [95% CI, 0.61-1.43], 1.83 [95% CI, 1.40-2.26]), respectively. Intraoperative PRBC transfusion was associated with increased incidence of PPCs, prolonged ICU stay, and ICU readmissions after isolated CABG surgery. [ABSTRACT FROM AUTHOR]

Abstract

The Society of Cardiovascular Anesthesiologists (SCA) is committed to improving the quality, safety, and value that cardiothoracic anesthesiologists bring to patient care. To fulfill this mission, the SCA supports the creation of peer-reviewed manuscripts that establish standards, produce guidelines, critically analyze the literature, interpret preexisting guidelines, and allow experts to engage in consensus opinion. The aim of this report, commissioned by the SCA President, is to summarize the distinctions among these publications and describe a novel SCA-supported framework that provides guidance to SCA members for the creation of these publications. The ultimate goal is that through a standardized and transparent process, the SCA will facilitate up-to-date education and implementation of best practices by cardiovascular and thoracic anesthesiologists to improve patient safety, quality of care, and outcomes.

8. One-piece versus two-piece ceramic dental implants

Author

Bollen, Curd, Hakobayan, Gagik, and Jörgens, Martin

Abstract

In this narrative review, a structured comparison between one-piece and two-piece zirconia dental implants is highlighted. Ceramic dental implants have long ceased to be hype; on the contrary, they can offer a significant addition to the daily dental implant practice. Not only do their favourable aesthetics play a significant role, but their ability to work completely metal-free is of added value, particularly for patients with a proven allergy for Grade 5 titanium. Furthermore, the fact that peri-implantitis seems to appear only incidentally is an important supporting argument for their use as well. Whereas the original design of zirconia implants was formerly always of a one-piece/one-phase structure (the monobloc design), nowadays, two-piece/two-phase designs (the so-called hybrid concept) are also widely utilised to restore missing teeth. Both concepts have advantages and disadvantages, scientifically as well as clinically.

9. Native Aortic Valve Resection Using a Novel Blade-Based Device

Author

Navarra, Emiliano, Bollen, Xavier, Zito, Francesco, de Kerchove, Laurent, El Khoury, Gebrine, and Parla, Astarci

Abstract

Objective: The aim of this study was to validate the use of a new resection device in patient candidates for surgical aortic valve replacement. We evaluated the efficacy of this new circular blade to resect the aortic valve and the efficacy to collect the debris during the resection.Methods: For this study, a single size instrument was used, with an external diameter of 22 mm, and patients were selected on the basis of the preoperative assessment of the aortic diameters.Results: From October 2018 to June 2019, 10 patient candidates for surgical aortic valve replacement were selected to undergo native aortic valve resection using a new device, before surgical valve implantation. The mean age of the patients was 74 ± 7.6 years, and 8 of 10 were male. The mean aortic annulus diameter, measured before the procedure, was 25.7 ± 1.57 mm. The resection was complete in 9 (90%) patients. In 1 patient, due to an imprecise positioning of the device, the valve resection was partial. None of the patients showed signs or symptoms due to debris embolism. In all patients, the postoperative course was uneventful.Conclusions: These preliminary results show that resection of the aortic valve using a circular foldable blade is feasible. This prototype, used during conventional surgery even through a small incision, provided an efficient tool to easily resect the valve without debris release.

Abstract

ObjectiveTo describe the long-term consequences of necrotising pancreatitis, including complications, the need for interventions and the quality of life.DesignLong-term follow-up of a prospective multicentre cohort of 373 necrotising pancreatitis patients (2005–2008) was performed. Patients were prospectively evaluated and received questionnaires. Readmissions (ie, for recurrent or chronic pancreatitis), interventions, pancreatic insufficiency and quality of life were compared between initial treatment groups: conservative, endoscopic/percutaneous drainage alone and necrosectomy. Associations of patient and disease characteristics during index admission with outcomes during follow-up were assessed.ResultsDuring a median follow-up of 13.5 years (range 12–15.5 years), 97/373 patients (26%) were readmitted for recurrent pancreatitis. Endoscopic or percutaneous drainage was performed in 47/373 patients (13%), of whom 21/47 patients (45%) were initially treated conservatively. Pancreatic necrosectomy or pancreatic surgery was performed in 31/373 patients (8%), without differences between treatment groups. Endocrine insufficiency (126/373 patients; 34%) and exocrine insufficiency (90/373 patients; 38%), developed less often following conservative treatment (p<0.001 and p=0.016, respectively). Quality of life scores did not differ between groups. Pancreatic gland necrosis >50% during initial admission was associated with percutaneous/endoscopic drainage (OR 4.3 (95% CI 1.5 to 12.2)), pancreatic surgery (OR 3.2 (95% CI 1.1 to 9.5) and development of endocrine insufficiency (OR13.1 (95% CI 5.3 to 32.0) and exocrine insufficiency (OR6.1 (95% CI 2.4 to 15.5) during follow-up.ConclusionAcute necrotising pancreatitis carries a substantial disease burden during long-term follow-up in terms of recurrent disease, the necessity for interventions and development of pancreatic insufficiency, even when treated conservatively during the index admission. Extensive (>50%) pancreatic parenchymal necrosis seems to be an important predictor of interventions and complications during follow-up.

13. Bisphosphonates attenuate age‐related muscle decline in Caenorhabditis elegans

Author

Slade, Luke, Bollen, Shelby E., Bass, Joseph J., Phillips, Bethan E., Smith, Kenneth, Wilkinson, Daniel J., Szewczyk, Nathaniel J., Atherton, Philip J., and Etheridge, Timothy

Abstract

Age‐related muscle decline (sarcopenia) associates with numerous health risk factors and poor quality of life. Drugs that counter sarcopenia without harmful side effects are lacking, and repurposing existing pharmaceuticals could expedite realistic clinical options. Recent studies suggest bisphosphonates promote muscle health; however, the efficacy of bisphosphonates as an anti‐sarcopenic therapy is currently unclear. Using Caenorhabditis elegansas a sarcopenia model, we treated animals with 100 nM, 1, 10, 100 and 500 μM zoledronic acid (ZA) and assessed lifespan and healthspan (movement rates) using a microfluidic chip device. The effects of ZA on sarcopenia were examined using GFP‐tagged myofibres or mitochondria at days 0, 4 and 6 post‐adulthood. Mechanisms of ZA‐mediated healthspan extension were determined using combined ZA and targeted RNAi gene knockdown across the life‐course. We found 100 nM and 1 μM ZA increased lifespan (P< 0.001) and healthspan [954 ± 53 (100 nM) and 963 ± 48 (1 μM) vs. 834 ± 59% (untreated) population activity AUC, P< 0.05]. 10 μM ZA shortened lifespan (P< 0.0001) but not healthspan (758.9 ± 37 vs. 834 ± 59, P> 0.05), whereas 100 and 500 μM ZA were larval lethal. ZA (1 μM) significantly improved myofibrillar structure on days 4 and 6 post‐adulthood (83 and 71% well‐organized myofibres, respectively, vs. 56 and 34% controls, P< 0.0001) and increased well‐networked mitochondria at day 6 (47 vs. 16% in controls, P< 0.01). Genes required for ZA‐mediated healthspan extension included fdps‐1/FDPS‐1 (278 ± 9 vs. 894 ± 17% population activity AUC in knockdown + 1 μM ZA vs. untreated controls, respectively, P< 0.0001), daf‐16/FOXO (680 ± 16 vs. 894 ± 17%, P< 0.01) and agxt‐2/BAIBA (531 ± 23 vs. 552 ± 8%, P> 0.05). Life/healthspan was extended through knockdown of igdb‐1/FNDC5 (635 ± 10 vs. 523 ± 10% population activity AUC in gene knockdown vs. untreated controls, P< 0.01) and sir‐2.3/SIRT‐4 (586 ± 10 vs. 523 ± 10%, P< 0.05), with no synergistic improvements in ZA co‐treatment vs. knockdown alone [651 ± 12 vs. 635 ± 10% (igdb‐1/FNDC5) and 583 ± 9 vs. 586 ± 10% (sir‐2.3/SIRT‐4), both P> 0.05]. Conversely, let‐756/FGF21 and sir‐2.2/SIRT‐4 were dispensable for ZA‐induced healthspan [630 ± 6 vs. 523 ± 10% population activity AUC in knockdown + 1 μM ZA vs. untreated controls, P< 0.01 (let‐756/FGF21) and 568 ± 9 vs. 523 ± 10%, P <0.05 (sir‐2.2/SIRT‐4)]. Despite lacking an endoskeleton, ZA delays Caenorhabditis eleganssarcopenia, which translates to improved neuromuscular function across the life course. Bisphosphonates might, therefore, be an immediately exploitable anti‐sarcopenia therapy.

Abstract

Childhood trauma is a known risk factor for trauma and stress-related disorders in adulthood. However, limited research has investigated the impact of childhood trauma on brain structure linked to later posttraumatic dysfunction. We investigated the effect of childhood trauma on white matter microstructure after recent trauma and its relationship with future posttraumatic dysfunction among trauma-exposed adult participants (n= 202) recruited from emergency departments as part of the AURORA Study. Participants completed self-report scales assessing prior childhood maltreatment within 2-weeks in addition to assessments of PTSD, depression, anxiety, and dissociation symptoms within 6-months of their traumatic event. Fractional anisotropy (FA) obtained from diffusion tensor imaging (DTI) collected at 2-weeks and 6-months was used to index white matter microstructure. Childhood maltreatment load predicted 6-month PTSD symptoms (b = 1.75, SE = 0.78, 95% CI = [0.20, 3.29]) and inversely varied with FA in the bilateral internal capsule (IC) at 2-weeks (p= 0.0294, FDR corrected) and 6-months (p= 0.0238, FDR corrected). We observed a significant indirect effect of childhood maltreatment load on 6-month PTSD symptoms through 2-week IC microstructure (b = 0.37, Boot SE = 0.18, 95% CI = [0.05, 0.76]) that fully mediated the effect of childhood maltreatment load on PCL-5 scores (b = 1.37, SE = 0.79, 95% CI = [−0.18, 2.93]). IC microstructure did not mediate relationships between childhood maltreatment and depressive, anxiety, or dissociative symptomatology. Our findings suggest a unique role for IC microstructure as a stable neural pathway between childhood trauma and future PTSD symptoms following recent trauma. Notably, our work did not support roles of white matter tracts previously found to vary with PTSD symptoms and childhood trauma exposure, including the cingulum bundle, uncinate fasciculus, and corpus callosum. Given the IC contains sensory fibers linked to perception and motor control, childhood maltreatment might impact the neural circuits that relay and process threat-related inputs and responses to trauma.

16. Association of Intraoperative Red Blood Cell Transfusions With Venous Thromboembolism and Adverse Outcomes After Cardiac Surgery.

Author

Raphael, Jacob, Feng, Xiaoke, Shotwell, Matthew S., Mazzeffi, Michael A., Bollen, Bruce A., Shah, Ashish S., and Kertai, Miklos D.

Abstract

Objective: We determined whether intraoperative packed red blood cell (PRBC) transfusion was associated with a higher incidence of hospital-acquired venous thromboembolic (HA-VTE) complications and adverse outcomes after isolated coronary artery bypass grafting (CABG) surgery. Background: Intraoperative PRBC has been associated with increased risk for postoperative deep venous thrombosis after cardiac surgery, but validation of these findings in a large, multi-institutional, national cohort of cardiac surgery patients has been lacking. Methods: A registry-based cohort study of 751,893 patients with isolated CABG between January 1, 2015, to December 31, 2019. Using propensity score-weighted regression analysis, we analyzed the effect of intraoperative PRBC on the incidence of HA-VTE and adverse outcomes. Results: Administration of 1, 2, 3, and ≥4 units of PRBC transfusion was associated with increased odds for HA-VTE [odds ratios (ORs): 1.27 (1.22–1.32), 1.21 (1.16–1.26), 1.93 (1.85–2.00), 1.82 (1.75–1.89)], deep venous thrombosis [ORs: 1.39 (1.33–1.46), 1.38 (1.32–1.44), 2.18 (2.09–2.28), 1.82 (1.74–1.91], operative mortality [ORs: 1.11 (1.08–1.14), 1.16 (1.13–1.19), 1.29 (1.26–1.32), 1.47 (1.43–1.50)], readmission within 30 days [ORs: 1.05 (1.04–1.06), 1.16 (1.13–1.19), 1.29 (1.26–1.32), 1.47 (1.43–1.50)], and a prolonged postoperative length of stay [mean difference in days, 0.23 (0.19–0.27), 0.34 (0.30–0.39), 0.69 (0.64–0.74), 0.77 (0.72–0.820]. The odds of pulmonary venous thromboembolism were lower for patients transfused with 1 or 2 units [ORs: 0.98 (0.91–1.06), 0.75 (0.68–0.81)] of PRBC but remained significantly elevated for those receiving 3 and ≥4 units [ORs: 1.19 (1.09–1.29), 1.35 (1.25–1.48)]. Conclusions: Intraoperative PRBC transfusion was associated with HA-VTE and adverse outcomes after isolated CABG surgery. [ABSTRACT FROM AUTHOR]

Abstract

Objective: The aim of this study was to explore the incidence, risk factors, clinical course and treatment of perforation and fistula of the gastrointestinal (GI) tract in a large unselected cohort of patients with necrotizing pancreatitis. Background: Perforation and fistula of the GI tract may occur in necrotizing pancreatitis. Data from large unselected patient populations on the incidence, risk factors, clinical outcomes, and treatment are lacking. Methods: We performed a post hoc analysis of a nationwide prospective database of 896 patients with necrotizing pancreatitis. GI tract perforation and fistula were defined as spontaneous or iatrogenic discontinuation of the GI wall. Multivariable logistic regression was used to explore risk factors and to adjust for confounders to explore associations of the GI tract perforation and fistula on the clinical course. Results: A perforation or fistula of the GI tract was identified in 139 (16%) patients, located in the stomach in 23 (14%), duodenum in 56 (35%), jejunum or ileum in 18 (11%), and colon in 64 (40%). Risk factors were high C-reactive protein within 48 hours after admission [odds ratio (OR): 1.19; 95% confidence interval (CI): 1.01–1.39] and early organ failure (OR: 2.76; 95% CI: 1.78–4.29). Prior invasive intervention was a risk factor for developing a perforation or fistula of the lower GI tract (OR: 2.60; 95% CI: 1.04–6.60). While perforation or fistula of the upper GI tract appeared to be protective for persistent intensive care unit-admission (OR: 0.11, 95% CI: 0.02–0.44) and persistent organ failure (OR: 0.15; 95% CI: 0.02–0.58), perforation or fistula of the lower GI tract was associated with a higher rate of new onset organ failure (OR: 2.47; 95% CI: 1.23–4.84). When the stomach or duodenum was affected, treatment was mostly conservative (n=54, 68%). Treatment was mostly surgical when the colon was affected (n=38, 59%). Conclusions: Perforation and fistula of the GI tract occurred in one out of six patients with necrotizing pancreatitis. Risk factors were high C-reactive protein within 48 hours and early organ failure. Prior intervention was identified as a risk factor for perforation or fistula of the lower GI tract. The clinical course was mostly affected by involvement of the lower GI tract. [ABSTRACT FROM AUTHOR]

Abstract

Cohort studies in adults with HIV showed that dolutegravir was associated with neuropsychiatric adverse events and sleep problems, yet data are scarce in children and adolescents. We aimed to evaluate neuropsychiatric manifestations in children and adolescents treated with dolutegravir-based treatment versus alternative antiretroviral therapy.

Abstract

Background: Clinicians and patients have reported fragmentation in the primary and tertiary healthcare interface. However, perspectives of service navigation and the impacts of fragmentation are not well defined, particularly for patients transitioning to dialysis. This study aimed to define patient perspectives of the functioning of the health service interface and impacts on healthcare experiences and engagement, informing patient-centred and outcomes-focused service models. Methods: A qualitative study was conducted through semi-structured interviews with 25 dialysis patients (16 males) aged 34–78 receiving dialysis across a multi-site tertiary service. Transcripts were analysed thematically. Results: Three main themes were identified: (1) The Changing Nature of General Practitioner (GP) Patient Relationships; (2) Ownership and Leadership in Kidney Care; and (3) The Importance of Nephrologist—GP Communications. Patients perceived an unreliable primary-tertiary service interface which lacked coordinated care and created challenges for primary care continuity. These impacted perceptions of healthcare provider expertise and confidence in healthcare systems. Patients subsequently increased the healthcare sought from tertiary kidney clinicians. The fractured interface led some to coordinate communication between health sectors, to support care quality, but this caused additional stress. Conclusions: A fragmented primary-tertiary healthcare interface creates challenges for patient service navigation and can negatively impact patient experiences, leading to primary care disengagement, reduced confidence in health care quality and increased stress. Future studies are imperative for assessing initiatives facilitating health system integration, including communication technologies, healthcare provider training, patient empowerment, and specific outcomes in health, economic and patient experience measures, for patients transitioning to dialysis.

Abstract

Key Points: Question: Can 24-hour rest-activity characteristics from wrist-wearable devices predict adverse posttraumatic neuropsychiatric symptoms following traumatic stress exposure? Findings: In this cohort study including 2021 participants observed over time after traumatic stress exposure, reduced 24-hour activity variance based on wrist accelerometry identified individuals with greater pain severity. Changes in several rest-activity measures were associated with changes in pain, sleep, and anxiety over time, and simple thresholds for these biomarkers identified individuals with good recovery for pain, sleep, and anxiety with high predictive value. Meaning: These findings suggest that wrist-activity biomarkers may have utility as screening tools for adverse pain, sleep, and anxiety symptom outcomes after trauma exposure. This cohort study evaluates whether wrist-wearable devices can provide useful biomarkers for recovery after traumatic stress exposure. Importance: Adverse posttraumatic neuropsychiatric sequelae after traumatic stress exposure are common and have higher incidence among socioeconomically disadvantaged populations. Pain, depression, avoidance of trauma reminders, reexperiencing trauma, anxiety, hyperarousal, sleep disruption, and nightmares have been reported. Wrist-wearable devices with accelerometers capable of assessing 24-hour rest-activity characteristics are prevalent and may have utility in measuring these outcomes. Objective: To evaluate whether wrist-wearable devices can provide useful biomarkers for recovery after traumatic stress exposure. Design, Setting, and Participants: Data were analyzed from a diverse cohort of individuals seen in the emergency department after experiencing a traumatic stress exposure, as part of the Advancing Understanding of Recovery After Trauma (AURORA) study. Participants recruited from 27 emergency departments wore wrist-wearable devices for 8 weeks, beginning in the emergency department, and completed serial assessments of neuropsychiatric symptoms. A total of 19 019 patients were screened. Of these, 3040 patients met study criteria, provided informed consent, and completed baseline assessments. A total of 2021 provided data from wrist-wearable devices, completed the 8-week assessment, and were included in this analysis. The data were randomly divided into 2 equal parts (n = 1010) for biomarker identification and validation. Data were collected from September 2017 to January 2020, and data were analyzed from May 2020 to November 2022. Exposures: Participants were recruited for the study after experiencing a traumatic stress exposure (most commonly motor vehicle collision). Main Outcomes and Measures: Rest-activity characteristics were derived and validated from wrist-wearable devices associated with specific self-reported symptom domains at a point in time and changes in symptom severity over time. Results: Of 2021 included patients, 1257 (62.2%) were female, and the mean (SD) age was 35.8 (13.0) years. Eight wrist-wearable device biomarkers for symptoms of adverse posttraumatic neuropsychiatric sequelae exceeded significance thresholds in the derivation cohort. One of these, reduced 24-hour activity variance, was associated with greater pain severity (r = −0.14; 95% CI, −0.20 to −0.07). Changes in 6 rest-activity measures were associated with changes in pain over time, and changes in the number of transitions between sleep and wake over time were associated with changes in pain, sleep, and anxiety. Simple cutoffs for these biomarkers identified individuals with good recovery for pain (positive predictive value [PPV], 0.85; 95% CI, 0.82-0.88), sleep (PPV, 0.63; 95% CI, 0.59-0.67, and anxiety (PPV, 0.76; 95% CI, 0.72-0.80) with high predictive value. Conclusions and Relevance: These findings suggest that wrist-wearable device biomarkers may have utility as screening tools for pain, sleep, and anxiety symptom outcomes after trauma exposure in high-risk populations.

26. Efficient Calculation of Switching Overvoltages Considering Corona Attenuation

Author

Lennerhag, Oscar, Lundquist, Jan, and Bollen, Math H. J.

Abstract

This article applies the Unscented Transform to calculate the 2%-value of switching overvoltages when considering the impact of trapped charge and corona attenuation. Simulations were performed using a piecewise linear corona model for twin- and triple-conductor lines. The proposed method was compared to Monte Carlo methods through simulations in PSCAD. The method is shown to be able to estimate the 2%-value with comparable accuracy to methods used in industry today, but with only one fifth of the number of calculations.

Abstract

Considerable racial/ethnic disparities persist in exposure to life stressors and socioeconomic resources that can directly affect threat neurocircuitry, particularly the amygdala, that partially mediates susceptibility to adverse posttraumatic outcomes. Limited work to date, however, has investigated potential racial/ethnic variability in amygdala reactivity or connectivity that may in turn be related to outcomes such as post-traumatic stress disorder (PTSD). Participants from the AURORA study (n= 283), a multisite longitudinal study of trauma outcomes, completed functional magnetic resonance imaging and psychophysiology within approximately two-weeks of trauma exposure. Seed-based amygdala connectivity and amygdala reactivity during passive viewing of fearful and neutral faces were assessed during fMRI. Physiological activity was assessed during Pavlovian threat conditioning. Participants also reported the severity of posttraumatic symptoms 3 and 6 months after trauma. Black individuals showed lower baseline skin conductance levels and startle compared to White individuals, but no differences were observed in physiological reactions to threat. Further, Hispanic and Black participants showed greater amygdala connectivity to regions including the dorsolateral prefrontal cortex (PFC), dorsal anterior cingulate cortex, insula, and cerebellum compared to White participants. No differences were observed in amygdala reactivity to threat. Amygdala connectivity was associated with 3-month PTSD symptoms, but the associations differed by racial/ethnic group and were partly driven by group differences in structural inequities. The present findings suggest variability in tonic neurophysiological arousal in the early aftermath of trauma between racial/ethnic groups, driven by structural inequality, impacts neural processes that mediate susceptibility to later PTSD symptoms.

Abstract

Pain after thoracic surgery is of moderate-to-severe intensity and can cause increased postoperative distress and affect functional recovery. Opioids have been central agents in treating pain after thoracic surgery for decades. The use of multimodal analgesic strategies can promote effective postoperative pain control and help mitigate opioid exposure, thus preventing the risk of developing persistent postoperative pain. This practice advisory is part of a series developed by the Society of Cardiovascular Anesthesiologists (SCA) Quality, Safety, and Leadership (QSL) Committee’s Opioid Working Group. It is a systematic review of existing literature for various interventions related to the preoperative and intraoperative pain management of thoracic surgical patients and provides recommendations for providers caring for patients undergoing thoracic surgery. This entails developing customized pain management strategies for patients, which include preoperative patient evaluation, pain management, and opioid use–focused education as well as perioperative use of multimodal analgesics and regional techniques for various thoracic surgical procedures. The literature related to this field is emerging and will hopefully provide more information on ways to improve clinically relevant patient outcomes and promote recovery in the future.

31. The impact of managers' personality on task and relationship conflict: The moderating role of family and non-family business status.

Author

Guerrero Calle, Maria Bernarda, Bollen, Katalien, Sucozhañay, Dolores, and Euwema, Martin

Abstract

When it comes to organizational conflict in (small) family businesses, managers' personality has received little attention. We investigated the relationship between managers' personality traits (Big Five) and their perceptions of task conflict and relationship conflict in two types of firms (family vs. non-family business). We collected data from 103 managers in small firms (56 family firms and 47 non-family firms) in Ecuador. Our findings show that family firms have less relationship conflict compared to non-family firms. Managers' personality seems to play a key role in perceiving conflicts. Particularly, managers' openness and extraversion are related to less perceived conflict. Introverted managers in non-family businesses perceive more relationship conflict than those in family businesses. Implications for theory and practice are discussed. • There is less relationship conflict perceived in family firms than in non-family firms. • Personality of managers relates to perceived task and relationship conflict. • By including firm type and personality, we offer a comprehensive picture of small firms. • Promote training for a greater self-awareness for managers in small firms.

33. An introduction to model implied instrumental variables using two stage least squares (MIIV-2SLS) in structural equation models (SEMs).

Author

Bollen, Kenneth A., Fisher, Zachary F., Giordano, Michael L., Lilly, Adam G., Lan Luo, and Ai Ye

Abstract

Structural equation models (SEMs) are widely used to handle multiequation systems that involve latent variables, multiple indicators, and measurement error. Maximum likelihood (ML) and diagonally weighted least squares (DWLS) dominate the estimation of SEMs with continuous or categorical endogenous variables, respectively. When a model is correctly specified, ML and DWLS function well. But, in the face of incorrect structures or nonconvergence, their performance can seriously deteriorate. Model implied instrumental variable, two stage least squares (MIIV-2SLS) estimates and tests individual equations, is more robust to misspecifications, and is noniterative, thus avoiding nonconvergence. This article is an overview and tutorial on MIIV-2SLS. It reviews the six major steps in using MIIV-2SLS: (a) model specification; (b) model identification; (c) latent to observed (L2O) variable transformation; (d) finding MIIVs; (e) using 2SLS; and (f) tests of overidentified equations. Each step is illustrated using a running empirical example from Reisenzein's (1986) randomized experiment on helping behavior. We also explain and illustrate the analytic conditions under which an equation estimated with MIIV-2SLS is robust to structural misspecifications. We include additional sections on MIIV approaches using a covariance matrix and mean vector as data input, conducting multilevel SEM, analyzing categorical endogenous variables, causal inference, and extensions and applications. Online supplemental material illustrates input code for all examples and simulations using the R package MIIVsem. [ABSTRACT FROM AUTHOR]

35. Computing a Stable Distance on Merge Trees

Author

Bollen, Brian, Tennakoon, Pasindu, and Levine, Joshua A.

Abstract

Distances on merge trees facilitate visual comparison of collections of scalar fields. Two desirable properties for these distances to exhibit are 1) the ability to discern between scalar fields which other, less complex topological summaries cannot and 2) to still be robust to perturbations in the dataset. The combination of these two properties, known respectively as stability and discriminativity, has led to theoretical distances which are either thought to be or shown to be computationally complex and thus their implementations have been scarce. In order to design similarity measures on merge trees which are computationally feasible for more complex merge trees, many researchers have elected to loosen the restrictions on at least one of these two properties. The question still remains, however, if there are practical situations where trading these desirable properties is necessary. Here we construct a distance between merge trees which is designed to retain both discriminativity and stability. While our approach can be expensive for large merge trees, we illustrate its use in a setting where the number of nodes is small. This setting can be made more practical since we also provide a proof that persistence simplification increases the outputted distance by at most half of the simplified value. We demonstrate our distance measure on applications in shape comparison and on detection of periodicity in the von Kármán vortex street.

Abstract

ObjectiveRoutine urgent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic biliary sphincterotomy (ES) does not improve outcome in patients with predicted severe acute biliary pancreatitis. Improved patient selection for ERCP by means of endoscopic ultrasonography (EUS) for stone/sludge detection may challenge these findings.DesignA multicentre, prospective cohort study included patients with predicted severe acute biliary pancreatitis without cholangitis. Patients underwent urgent EUS, followed by ERCP with ES in case of common bile duct stones/sludge, within 24 hours after hospital presentation and within 72 hours after symptom onset. The primary endpoint was a composite of major complications or mortality within 6 months after inclusion. The historical control group was the conservative treatment arm (n=113) of the randomised APEC trial (Acute biliary Pancreatitis: urgent ERCP with sphincterotomy versus conservative treatment, patient inclusion 2013–2017) applying the same study design.ResultsOverall, 83 patients underwent urgent EUS at a median of 21 hours (IQR 17–23) after hospital presentation and at a median of 29 hours (IQR 23–41) after start of symptoms. Gallstones/sludge in the bile ducts were detected by EUS in 48/83 patients (58%), all of whom underwent immediate ERCP with ES. The primary endpoint occurred in 34/83 patients (41%) in the urgent EUS-guided ERCP group. This was not different from the 44% rate (50/113 patients) in the historical conservative treatment group (risk ratio (RR) 0.93, 95% CI 0.67 to 1.29; p=0.65). Sensitivity analysis to correct for baseline differences using a logistic regression model also showed no significant beneficial effect of the intervention on the primary outcome (adjusted OR 1.03, 95% CI 0.56 to 1.90, p=0.92).ConclusionIn patients with predicted severe acute biliary pancreatitis without cholangitis, urgent EUS-guided ERCP with ES did not reduce the composite endpoint of major complications or mortality, as compared with conservative treatment in a historical control group.Trial registration numberISRCTN15545919.

Abstract

ObjectiveLumen-apposing metal stents (LAMS) are believed to clinically improve endoscopic transluminal drainage of infected necrosis when compared with double-pigtail plastic stents. However, comparative data from prospective studies are very limited.DesignPatients with infected necrotising pancreatitis, who underwent an endoscopic step-up approach with LAMS within a multicentre prospective cohort study were compared with the data of 51 patients in the randomised TENSION trial who had been assigned to the endoscopic step-up approach with double-pigtail plastic stents. The clinical study protocol was otherwise identical for both groups. Primary end point was the need for endoscopic transluminal necrosectomy. Secondary end points included mortality, major complications, hospital stay and healthcare costs.ResultsA total of 53 patients were treated with LAMS in 16 hospitals during 27 months. The need for endoscopic transluminal necrosectomy was 64% (n=34) and was not different from the previous trial using plastic stents (53%, n=27)), also after correction for baseline characteristics (OR 1.21 (95% CI 0.45 to 3.23)). Secondary end points did not differ between groups either, which also included bleeding requiring intervention—5 patients (9%) after LAMS placement vs 11 patients (22%) after placement of plastic stents (relative risk 0.44; 95% CI 0.16 to 1.17). Total healthcare costs were also comparable (mean difference −€6348, bias-corrected and accelerated 95% CI −€26 386 to €10 121).ConclusionOur comparison of two patient groups from two multicentre prospective studies with a similar design suggests that LAMS do not reduce the need for endoscopic transluminal necrosectomy when compared with double-pigtail plastic stents in patients with infected necrotising pancreatitis. Also, the rate of bleeding complications was comparable.

39. Occlusal contact changes in patients treated with clear aligners: A retrospective evaluation using digital dental models.

Author

Frenkel, Erica Shapiro, Mustafa, Mariam, Khosravi, Roozbeh, Woloshyn, Heather, Mancl, Lloyd, and Bollen, Anne-Marie

Abstract

This study used digital intraoral scans to evaluate how clear aligner treatment affects occlusal contacts and to determine the influence of sex and age on contact changes. Results were compared with contact changes that occur during fixed appliance therapy. Patients included in this study were treated in a University setting and private practice. Inclusion criteria were a Class I malocclusion treated nonextraction with clear aligners and the presence of pretreatment and posttreatment digital intraoral scans. Scans were imported into specialized software, and occlusal contacts were analyzed. The effects of age and sex on contact changes during clear aligner treatment were determined. Changes in occlusal contacts were compared with changes that occur during nonextraction treatment of patients with a Class I relationship using fixed edgewise appliances. A total of 45 clear aligner patients fit the eligibility criteria. Clear aligner treatment reduced the percentage of tight, near, and approximating contacts, whereas the percentage of open and no contacts increased. These changes in occlusal contacts were greater for the older age group studied. Genderinfluenced occlusal contact changes in the anterior dentition only where the decrease in near contacts and increase in open contacts were greater for males. These results for patients treated with clear aligners were similar to those for patients treated with fixed appliances; both treatment modalities reduced close occlusal contacts at the time active treatment was completed. These results indicated that when clear aligners or fixed appliances are used to treat a Class I malocclusion, the resulting occlusion immediately after debonding is not as "tight" as it was at pretreatment. • Digital intraoral scans were used to determine occlusal contact changes during clear aligner treatment. • Clear aligners reduced near contacts and increased open contacts. • Occlusal contact changes during clear aligner therapy were greater in older patients. • Clear aligners and fixed appliances have similar effects on occlusal contacts.

Abstract

Purpose: Older critically ill patients with COVID-19 have been the most vulnerable during the ongoing pandemic, with men being more prone to hospitalization and severe disease than women. We aimed to explore sex-specific differences in treatment and outcome after intensive care unit (ICU) admission in this cohort. Methods: We performed a sex-specific analysis in critically ill patients ≥ 70 yr of age with COVID-19 who were included in the international prospective multicenter COVIP study. All patients were analyzed for ICU admission and treatment characteristics. We performed a multilevel adjusted regression analysis to elucidate associations of sex with 30-day mortality. Results: A total of 3,159 patients (69.8% male, 30.2% female; median age, 75 yr) were included. Male patients were significantly fitter than female patients as determined by the Clinical Frailty Scale (fit, 67% vs54%; vulnerable, 14% vs19%; frail, 19% vs27%; P&lt; 0.001). Male patients more often underwent tracheostomy (20% vs14%; odds ratio [OR], 1.57; P&lt; 0.001), vasopressor therapy (69% vs62%; OR, 1.25; P= 0.02), and renal replacement therapy (17% vs11%; OR, 1.96; P&lt; 0.001). There was no difference in mechanical ventilation, life-sustaining treatment limitations, and crude 30-day mortality (50% male vs49% female; OR, 1.11; P= 0.19), which remained true after adjustment for disease severity, frailty, age and treatment limitations (OR, 1.17; 95% confidence interval, 0.94 to 1.45; P= 0.16). Conclusion: In this analysis of sex-specific treatment characteristics and 30-day mortality outcomes of critically ill patients with COVID-19 ≥ 70 yr of age, we found more tracheostomy and renal replacement therapy in male vsfemale patients, but no significant association of patient sex with 30-day mortality.

Abstract

Cardiac surgery-associated acute kidney injury (CS-AKI) is common and is associated with increased risk for postoperative morbidity and mortality. Our recent survey of the Society of Cardiovascular Anesthesiologists (SCA) membership showed 6 potentially renoprotective strategies for which clinicians would most value an evidence-based review (ie, intraoperative target blood pressure, choice of specific vasopressor agent, erythrocyte transfusion threshold, use of alpha-2 agonists, goal-directed oxygen delivery on cardiopulmonary bypass [CPB], and the “Kidney Disease Improving Global Outcomes [KDIGO] bundle of care”). Thus, the SCA’s Continuing Practice Improvement Acute Kidney Injury Working Group aimed to provide a practice update for each of these strategies in cardiac surgical patients based on the evidence from randomized controlled trials (RCTs). PubMed, EMBASE, and Cochrane library databases were comprehensively searched for eligible studies from inception through February 2021, with search results updated in August 2021. A total of 15 RCTs investigating the effects of the above-mentioned strategies on CS-AKI were included for meta-analysis. For each strategy, the level of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. Across the 6 potentially renoprotective strategies evaluated, current evidence for their use was rated as “moderate,” “low,” or “very low.” Based on eligible RCTs, our analysis suggested using goal-directed oxygen delivery on CPB and the “KDIGO bundle of care” in high-risk patients to prevent CS-AKI (moderate level of GRADE evidence). Our results suggested considering the use of vasopressin in vasoplegic shock patients to reduce CS-AKI (low level of GRADE evidence). The decision to use a restrictive versus liberal strategy for perioperative red cell transfusion should not be based on concerns for renal protection (a moderate level of GRADE evidence). In addition, targeting a higher mean arterial pressure during CPB, perioperative use of dopamine, and use of dexmedetomidine did not reduce CS-AKI (a low or very low level of GRADE evidence). This review will help clinicians provide evidence-based care, targeting improved renal outcomes in adult patients undergoing cardiac surgery.

Abstract

Situated in a Japanese university ELT context, this qualitative exploratory interview-based study offers insights into how ten teachers responded to the challenges of transitioning to emergency remote teaching (ERT). The research was conducted to understand the implications of pandemic-instigated educational changes on teaching practices and perspectives towards effective teaching. An activity theory perspective accounts for the complex interlinking internal and external factors influencing teachers' experiences during and since the ERT. Data were obtained through semi-structured interviews with the ten teachers following the initial period of ERT and through reflective writing by the same teachers 12 months later. Key findings from a content analysis were that perspectives towards effective teaching were generally reinforced and that following reflection on pedagogical practices and professional learning directions many teachers were able to respond effectively to ongoing educational changes. We argue that the implications of the study may reveal important areas of comparison with other systems of activity in heightened states of transition and reveal pathways to the development of new practices.

Abstract

The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) is the world's premier clinical outcomes registry for adult cardiac surgery and a driving force for quality improvement in cardiac surgery. Echocardiographic data provide a wealth of hemodynamic, structural, and functional data and have been part of STS ACSD data collection since its inception. An increasing body of evidence suggests that the use of echocardiography in patients undergoing cardiac surgery has a positive impact on postoperative outcomes. In this report, we describe and summarize the type and rate of reporting of echocardiography-related variables in the STS ACSD, including the Adult Cardiac Anesthesiology Module, from July 2017 to December 2019 for the most frequently performed cardiac surgical procedures. With this review, we aim to increase awareness of the importance of collecting accurate and consistent echocardiography data in the STS ACSD and to highlight opportunities for growth and improvement.

Abstract

Implant loss due to infection is the most devastating complication of implant-based breast reconstruction. The use of negative pressure wound therapy with instillation(NPWTi) for salvage of infected implant-based breast reconstructions has shown promising results allowing early reinsertion of a new implant as an alternative to the current management with delayed reinsertion. This study compares the patient-reported outcome and cost implication of NPWTi to the current management. Twenty cases of infected breast implants treated with NPWTi(V.A.C. VERAFLO™ Therapy), followed by early reinsertion of new implants were compared to 20 cases that had delayed reinsertion(non-NPWTi). Patient satisfaction was evaluated using the BREAST-Q questionnaire. The average cost per patient was calculated using total operative expense, cost of inpatient stay, investigations, antibiotics, and outpatient visits. Treatment with NPWTi allowed earlier reinsertion of a new implant (NPWTi: 10.3 ± 2.77days vs. non-NPWTi: 247.45±111.28days, p <0.001). Patients in the NPWTi group reported higher satisfaction. The average cost per patient for NPWTi and non-NPWTi was £14,343.13±£2,786.70 and £8,920.31±£3,005.73, respectively(p <0.001). All patients treated with NPWTi had one admission and spent 11.9 ± 4.1days as inpatients, while non-NPWTi patients had 2.1 ± 0.3 admissions(p <0.001) and spent 7.1 ± 5.8days(p <0.004) as inpatients. Patients treated with NPWTi had more procedures (NPWTi:3.35±0.81 Vs. non-NPWTi:2.2 ± 0.41, p = 0.006); however, three non-NPWTi cases required flap reconstruction. Patients treated with NPWTi reported higher satisfaction, received a new and earlier implant, and had fewer admissions and outpatient visits; however, they incurred higher average costs, longer inpatient stays, and underwent more procedures. Early implant reinsertion preserves skin envelope; hence avoiding additional cost and stress related to further major autologous reconstruction. [ABSTRACT FROM AUTHOR]

Abstract

We tested the hypothesis that dexmedetomidine was associated with a reduced incidence of postoperative delirium (POD) and adverse outcomes in cardiac surgery patients from The Society of Thoracic Surgeons Adult Cardiac Surgery Database including the Adult Cardiac Anesthesiology subsection. We identified 55,905 patients in The Society of Thoracic Surgeons Adult Cardiac Surgery Database who underwent cardiac surgery between July 2014 and December 2018. Using propensity score–weighted regression analysis, we analyzed the effect of intraoperative dexmedetomidine on the primary (POD) and secondary outcomes (highest pain score on day 3 and at discharge, stroke, prolonged ventilation, postoperative intubation/reintubation, additional postoperative hours ventilated, renal failure, atrial fibrillation, and 30-day mortality). In separate propensity score–weighted analyses, we examined the effect of postoperative dexmedetomidine on the highest postoperative pain score at discharge and 30-day mortality. The rate of intraoperative dexmedetomidine use was 25.5% (n = 13,963), and its administration was associated with increased odds for POD (odds ratio, 1.85; 95% confidence interval [CI], 1.60-2.13), a small higher average pain score on day 3 (mean difference, 0.08; 95% CI, 0.02-0.14), increased odds for postoperative intubation/reintubation (odds ratio, 1.29; 95% CI, 1.12-1.48), and a small lower average pain score at discharge (mean difference, –0.31; 95% CI, –0.21 to–0.41). Postoperative dexmedetomidine was associated with a small higher average pain score at discharge (mean difference, 0.27; 95% CI, 0.21-0.34) and higher odds for 30-day mortality (odds ratio, 1.25, 95% CI, 1.07-1.46). In this registry of cardiac surgical patients dexmedetomidine administration was associated with POD and adverse outcomes. [Display omitted] [ABSTRACT FROM AUTHOR]

Abstract

Composite pleomorphic xanthoastrocytoma-ganglioglioma (PXA-GG) is an extremely rare central nervous system neoplasm with 2 distinct but intermingled components. Whether this tumor represents a “collision tumor” of separate neoplasms or a monoclonal neoplasm with divergent evolution is poorly understood. Clinicopathologic studies and capture-based next generation sequencing were performed on extracted DNA from all available PXA-GG at 2 medical centers. Five PXA-GG were diagnosed in 1 male and 4 female patients ranging from 13 to 25 years in age. Four arose within the cerebral hemispheres; 1 presented in the cerebellar vermis. DNA was sufficient for analysis in 4 PXA components and 3 GG components. Four paired PXA and GG components harbored BRAFp.V600E hotspot mutations. The 4 sequenced PXA components demonstrated CDKN2Ahomozygous deletion by sequencing with loss of p16 (protein product of CDKN2A) expression by immunohistochemistry, which was intact in all assessed GG components. The PXA components also demonstrated more frequent copy number alterations relative to paired GG components. In one PXA-GG, shared chromosomal copy number alterations were identified in both components. Our findings support divergent evolution of the PXA and GG components from a common BRAFp.V600E-mutant precursor lesion, with additional acquisition of CDKN2Ahomozygous deletion in the PXA component as is typically seen in conventional PXA.
