Abstract
Background Documentation burden is one of the largest contributors to physician burnout. Evaluation and Management (E&M) coding changes were implemented in 2021 to alleviate documentation burden.
Objectives We used this opportunity to develop documentation best practices, implement new electronic health record (EHR) tools, and study the potential impact on provider experiences with documentation related to these 2021 E&M changes, documentation length, and time spent documenting at an academic medical center.
Methods Five actionable best practices, developed through a consensus-driven, multidisciplinary approach in November 2020, led to the creation of two new ambulatory note templates, one for E&M visits (implemented in January 2021) and another for preventative visits (implemented in May 2021). As part of a quality-improvement initiative at nine faculty primary care clinics, surveys were developed utilizing a 5-point Likert scale to assess provider perceptions and deidentified EHR metadata (Signal, Epic Systems) were analyzed to measure changes in EHR use metrics between a pre-E&M changes timeframe (August 2020–December 2020) and a post-E&M change timeframe (August 2021–December 2021). A subgroup analysis was conducted comparing EHR use metrics among note template utilizers versus nonutilizers. Any provider who used one of the note templates at least once was categorized as a utilizer.
Results Between January 2021 and December 2021, the adoption of the E&M visit template was 31,480 instances among 120 unique ambulatory providers, and adoption of the preventative visit template was 1,464 instances among 22 unique ambulatory providers. Survey response rate among faculty primary care providers was 82% (88/107): 55% (48/88) believed the 2021 E&M changes provided an opportunity to reduce documentation burden, and 28% reported favorable satisfaction with time spent documenting. Among providers who reported using one or both of the new note templates, 81% (35/43) of survey respondents reported favorable satisfaction with new note templates. EHR use metric analyses revealed a small, yet significant reduction in time in notes per appointment (p = 0.004) with no significant change in documentation length of notes (p = 0.45). Note template utilization was associated with a statistically significant reduction in documentation length (p = 0.034).
Conclusion This study shows modest progress in improving EHR use measures of documentation length and time spent documenting following the 2021 E&M changes, but without great improvement in perceived documentation burden. Additional tools are needed to reduce documentation burden and further research is needed to understand the impact of these interventions.

Abstract
Purpose The most important cause of mortality and morbidity in acute
rheumatic fever (ARF) is carditis and rheumatic heart disease (RHD). The aim of
this study was to identify markers that may be indicators of chronic
inflammation in whole blood analyses in pediatric patients with RHD who
regularly received secondary deposilin prophylaxis.
Methods In our study, 100 children with ARF aged between 4 and 18 years
were followed up in the pediatric cardiology outpatient clinic of the patient
group. The control group consisted of 100 healthy children of the same sex and
age as the patient group. All children in the patient group regularly received
deposilin prophylaxis every 21 days. Our study included many whole blood
parameters that are reported in the literature to represent changes in chronic
inflammatory diseases. These parameters were CRP, RDW, PDW, MPV and leukocyte
subtypes, neutrophil, lymphocyte, monocyte counts and their ratios
(neutrophil/lymphocyte, platelet/lymphocyte and monocyte/lymphocyte).
Results Leukocyte count, lymphocyte count, basophil count, MLR and
basophil count were significantly lower in the patient group than in the control
group (p: 0.047, p: 0.023, p: 0.006). In addition, eosinophil count and RDW
value were significantly higher in the patient group than in the control group
(p: 0.043; p: 0.001).
Conclusion In our study, low leukocyte, lymphocyte, basophil, MLR and
higher eosinophil counts indicated that RDW could be effectively used as a
marker for regular depositilin prophylaxis in pediatric patients with RHD.

AbstractThe purpose of this study was to investigate factors that influence clinical outcomes after anterior cruciate ligament (ACL) reconstruction in patients aged ≥40 years. We studied 264 patients aged ≥40 and 154 patients aged ≤20 years who underwent ACL reconstruction at several surgical centers. A logistic regression analysis was conducted to identify factors that influenced the Knee Injury and Osteoarthritis Outcome Score (KOOS) at 1 year post-ACL reconstruction. In the older patient group, cartilage damage in the patellofemoral compartment at surgery was a significant risk factor for poor postoperative KOOS subscores (pain, activities of daily living [ADL], sports, and quality of life [QOL]). Articular cartilage damage in the lateral compartment also significantly influenced one of the postoperative KOOS subscores (symptoms). In the younger patient group, articular cartilage damage in any compartments did not influence the postoperative KOOS subscores; only two preoperative KOOS subscores (symptoms and QOL) significantly influenced their postoperative KOOS subscores. We concluded that the articular cartilage damage in the patellofemoral compartment at ACL reconstruction predicts poor KOOS subscores at the 1-year follow-up in patients aged ≥40 years.

AbstractA substantial proportion of Hong Kong's aging population suffers from osteoarthritis in both knees. Bilateral total knee arthroplasty (BTKA) is a surgical option for addressing this condition and can be performed via two approaches: simultaneous BTKA (SimBTKA) and staged BTKA (StaBTKA). We compared the cost-effectiveness and safety of these two methods in our institution. We retrospectively reviewed 2,372 patients (SimBTKA, 772; StaBTKA, 1,600; females, 1,780; males, 592; mean age at SimBTKA, 70.4 ± 7.99 years; mean age at StaBTKA, 66.4 ± 7.50 years; p < 0.001) who underwent BTKA in our institution from 2001 to 2022. Patients were categorized according to the surgical approach. Patients undergoing BTKA in our institution were included. Particularly for SimBTKA, patients were assessed by anesthetists to be medically fit before undergoing the procedure according to their age, American Society of Anesthesiologists status, and osteoarthritis severity. The primary outcome was the length of stay (LOS) after surgery. The secondary outcomes were the 30-day unintended readmission, intensive care unit (ICU) admission, and death. SimBTKA had a shorter mean total LOS (acute hospital + rehabilitation center; SimBTKA, 13.09 days; StaBTKA, 18.12 days; p < 0.001) and mean LOS in acute hospital (SimBTKA, 7.70 days; StaBTKA, 10.42 days; p < 0.001). However, no significant difference was found in the mean LOS in rehabilitation centers (SimBTKA, 5.47 days; StaBTKA, 6.32 days; p > 0.05) between the two approaches. The 30-day unintended readmission rate was lower in SimBTKA (SimBTKA, 2.07%; StaBTKA, 3.30%; odds ratio [OR] = 1.60; p > 0.05) but statistically insignificant. SimBTKA was less costly than StaBTKA by US$ 8,422.22 per patient. No significant differences in ICU admission and death rates were found (p > 0.05) between the two groups. SimBTKA had a shorter LOS and lower cost than StaBTKA and comparable complication rates. Therefore, SimBTKA should be indicated in medically stable patients.

AbstractCerebral palsy (CP) is a neurodevelopmental condition that can result in altered gait biomechanics, joint dysfunction, and imbalance. The complications associated with total knee arthroplasty (TKA) in patients with CP have not yet been well described. Therefore, our analysis sought to compare the 90-day and 2-year complications following TKA in patients with and without CP. The PearlDiver Mariner database was utilized to identify patients with CP undergoing primary TKA between 2010 and 2020. This cohort was matched 1:4 to a control cohort without neurodegenerative disorders based on age, sex, Elixhauser Comorbidity Index (ECI), tobacco use, obesity, and diabetes. A total of 3,257 patients (657 CP patients 2,600 controls) were included in our final analysis. A multivariable logistic regression analysis was utilized to determine the risk of CP on medical and surgical complications at 90 days and all-cause revision rates at 2 years. Patients with CP had an increased risk of acute kidney injury (odds ratio [OR]: 1.66; 95% confidence interval [CI]: 1.07–2.5; p = 0.019), pneumonia (OR: 5.63; 95% CI: 3.69–8.67; p < 0.001), urinary tract infection (OR: 5.01; 95% CI: 3.85–6.52; p < 0.001), and transfusion (OR: 2.21; 95% CI: 1.50–3.23; p < 0.001). CP patients additionally had a higher incidence of emergency department (ED) visits (OR: 5.24; 95% CI: 3.76–7.32; p < 0.001) and readmissions (OR: 5.24; 95% CI: 2.57–4.96; p < 0.001). There were no differences in rates of periprosthetic joint infection (PJI; OR: 1.23; 95% CI: 0.69–2.10; p = 0.463), surgical site infection (SSI; OR: 0.51; 95% CI: 0.12–1.46; p = 0.463), and reoperation (OR: 1.35; 95% CI: 0.71–2.43; p = 0.339) at 90 days postoperatively. The all-cause revision rates at 2 years were comparable (OR: 1.02; 95% CI: 0.67–1.51; p = 0.927). In this database review, we found that CP patients have a higher risk of medical complications in the acute postoperative period following TKA. The 90-day surgical complication and 2-year revision rates in CP patients were comparable to matched controls.

Abstract
Background This meta-regression aims to investigate risk factors for abdominal hernia and bulge in patients undergoing deep inferior epigastric perforator (DIEP) flaps and the effect of prophylactic mesh placement on postoperative complications.
Methods A systematic search was conducted in July of 2022 in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Seventy-four studies published between 2000 and 2022 met the inclusion criteria. Sixty-four studies were included in the analysis for bulge and 71 studies were included in the analysis for hernia. Meta-regressions were run on the proportion of patients experiencing hernia or bulge to assess for patient risk factors and the role of prophylactic mesh placement. Proportions were transformed using the Freeman–Tukey double arcsine method.
Results The average rates of hernia and bulge after DIEP flaps were found to be 0.18% and 1.26%, respectively. Increased age (β = 0.0059, p = 0.0117), prior abdominal surgery (β = 0.0008, p = 0.046), and pregnancy history (β = −0.0015, p = 0.0001) were significantly associated with hernia. Active smoking (β = 0.0032, p = 0.0262) and pregnancy history (β = 0.0019, p < 0.0001) were significantly associated with bulge. Neither the perforator vessel laterality nor the number of perforator vessels harvested had any association with hernia or bulge. Prophylactic mesh placement was not associated with hernia or bulge.
Conclusion Understanding the comorbidities associated with hernia or bulge following DIEP flap breast reconstruction, such as advanced age, prior abdominal surgery, pregnancy history, and active smoking status, allows surgeons to proactively identify and educate high-risk patients. Future studies may further explore whether prophylactic mesh placement offers patients any benefit.

Abstract
Purpose The purpose of this article is to classify hepatocellular carcinoma (HCC) based on imaging and to evaluate the role of ultrasound-guided microwave ablation (MWA) in the management of type 2 exophytic HCC.
Materials and Methods A retrospective study was performed at our institution after approval by the Institutional Review Board. The study was undertaken from January 2017 to May 2022. Based on the location, HCC was classified and categorized on cross-sectional imaging into four types. All MWA procedures were performed using ultrasound guidance. Patients were followed up every 3 months with cross-sectional imaging.
Results During the study period, 225 lesions were reviewed. MWA was performed in 13 type 2 exophytic HCC patients. Segment 3 (38%) was the most common site when categorized as per Couinaud classification and segment 6 was the next common site. Technical success of complete ablation, evaluated by postprocedure contrast-enhanced computed tomography scan, was 100%. The median follow-up period was 24 months (range: 9–24 months). One patient presented with a residual lesion on the first follow-up at 30 days. Two other patients followed up to 9 months were free of HCC. Ten patients followed up at 1 year showed no recurrence, while 7 of them were followed up for 24 months, and 1 of whom showed multicentric recurrence which was treated by selective intra-arterial radiation therapy.
Conclusion A classification system for exophytic lesions can allow for better patient selection, planning, and reporting of ablative outcomes. MWA has performed well when ablating these technically challenging lesions with a certain degree of planning.

Published: July 2024

AbstractPeople’s negative attitudes to vaccines can be motivated by psychological factors—such as fears, ideological beliefs, and cognitive patterns—known as ‘attitude roots’. This study had two primary objectives: (1) to identify which of 11 known attitude roots are featured in individuals’ self-expressed reasons for negative vaccine attitudes (i.e., a linguistic analysis); (2) to explore how attitude roots present in self-expressed texts are linked to specific psychological measures. To achieve Objective 1, our study collected data from December 2022 to January 2023 from 556 participants from the US, who wrote texts to explain the reasons for their negative vaccine attitudes. The texts encompassed 2327 conceptually independent units of anti-vaccination argumentation, that were each coded for its attitude root(s) by at least two psychological experts. By allowing participants to spontaneously express their attitudes in their own words, we were able to observe how this differed from what participants reported to endorse when presented with a list of arguments. We found that there were four groups of attitude roots based on linguistic similarity in self-expression. In addition, latent class analysis of participants’ coded texts identified three distinct groups of participants that were characterised by their tendency to express combinations of arguments related to (1) fears, (2) anti-scientific conceptions, and (3) politicised perspectives. To achieve Objective 2, we collected participants’ responses to 11 validated measures of psychological constructs expected to underlie the respective 11 attitude roots, and used a correlational design to investigate how participants’ self-expressed attitude roots were linked to these measures. Logistic regressions showed that an expected psychological construct was the strongest, and significant, predictor for expression of three out of the four attitude root groups. We discuss the implications of these findings for health communicators and practitioners.
Methods for aggregating investor sentiment from social media
Authors: Liu Qing , Son Hosung 
Published: July 2024

AbstractSocial media-based investor sentiment proxies provide a brand new solution to recognize and measure investor sentiment. Aggregating individual social media text sentiments into public sentiments through a specific aggregation method is a necessary part of constructing an investor sentiment index for social media. The choice or design of the aggregation method directly affects whether or not the researcher can capture the sentiment of the market. This study provides the first systematic review of mainstream methods for aggregating investor sentiment from social media. In addition, we systematically discuss some of the key issues of historical researchers in aggregating investor sentiment, such as neutral sentiment text, simple aggregation of directly aggregated text, etc. The findings suggest that the aggregation method used by researchers directly affects the reliability of investor sentiment indices. Therefore, scholars should carefully choose sentiment aggregation algorithms based on the combination of datasets and sentiment tracking tools and articulate their rationale. This study provides important references for behavioral finance, social media mining, and microinvestor sentiment metrics.

Published: July 2024

We developed impedance-matched metal-powder low-pass filters based on coplanar waveguide design and characterized them at room temperature and 77.4 K. The coplanar waveguide metal-powder (CPW-MP) filters have a return loss better than 9.8 dB at frequencies up to 10 GHz at 77.4 K. We find that the filter attenuation per length scales linearly with frequency from 29 to 220 dB/m within the 1–5 GHz frequency range at 77.4 K, achieving the total attenuation above 100 dB for the 1 m-long CPW-MP filter at frequencies above 2 GHz. The CPW-MP filter integrated with the multipole LC filter demonstrates the low cut-off frequency, the attenuation above 100 dB in the stop band, and the high roll-off of 590 dB per decade. The proposed CPW-MP filter is easy to fabricate, has very good thermal-shock resistance, is flexible for integration with other types of low-pass filters, delivers the same performance as classical cryogenic filters, is more compact compared to 50 Ω coax cables with the same type of lossy dielectric, and provides ample opportunities for further miniaturization.

Published: July 2024

We report the x-ray absorption spectrum (XAS) of the tert-butyl radical, C4H9. The radical was generated pyrolytically from azo-tert-butane, and the XAS of the pure radical was obtained by subtraction of spectra recorded at different temperatures. The bands in the XAS were assigned by ab initio calculations that are in very good agreement with the experimental data. The lowest energy signal in the XAS is assigned to the C1s electron transition from the central carbon atom to the singly occupied molecular orbital (SOMO), while higher transitions correspond to C1s excitations from terminal carbon atoms. Furthermore, we investigated the fragmentation of the radical following resonant C1s excitation by electron–ion-coincidence spectroscopy. Several fragmentation channels were identified. The C1s excitation of the terminal carbons is associated with a stronger fragmentation tendency compared to the lowest C1s excitation of the central carbon into the SOMO. For this core excited state, we still observe an intact parent ion, C4H9+, and a comparatively higher tendency to dissociate into CH3+ + C3H6+.

We investigated the structure of ice under nanoporous confinement in periodic mesoporous organosilicas (PMOs) with different organic functionalities and pore diameters between 3.4 and 4.9 nm. X-ray scattering measurements of the system were performed at temperatures between 290 and 150 K. We report the emergence of ice I with both hexagonal and cubic characteristics in different porous materials, as well as an alteration of the lattice parameters when compared to bulk ice. This effect is dependent on the pore diameter and the surface chemistry of the respective PMO. Investigations regarding the orientation of hexagonal ice crystals relative to the pore wall using x-ray cross correlation analysis reveal one or more discrete preferred orientation in most of the samples. For a pore diameter of around 3.8 nm, stronger correlation peaks are present in more hydrophilically functionalized pores and seem to be connected to stronger shifts in the lattice parameters.

Abstract
Obtaining amorphous alloys with good mechanical and anticorrosion properties is an important problem of modern condensed matter physics. Since the preparation of amorphous alloys involves casting them from liquid state, information on the properties of the melts is needed. Viscosity is one of the most informative structure-sensitive property of melts. In this paper viscosity of some glass-forming Al–Ni–Co–Nd(Sm) melts with different ratio of transition metals was studied using damped oscillation method in a wide temperature range up to 1550 K. Activation energies of the viscous flow were calculated from the experimental data. The hysteresis of viscosity temperature dependences during heating and subsequent cooling was found. It can be associated with a melt transition to a more homogeneous state. The repeated heating and cooling of the melts without crystallization lead to Arrhenius type of viscosity temperature dependences.
