Abstract
BACKGROUND There exists an increasing array of treatments proposed to prevent, alleviate, and abort symptoms of a migraine; however, for patients who undergo reconstructive microsurgery, caution must be taken to preserve vascular integrity. This study is the first-to-date scoping review of vascular and bleeding risk of current migraine therapies, with the purpose of identifying potential therapeutic agents for postoperative migraine management appropriate for microsurgical patients. METHODS Currently available migraine therapeutics were compiled from the UpToDate software system and the American Academy of Family Physicians. A PubMed literature review was performed for each therapeutic's effect on bleeding or vascular involvement. Data were compiled into tables of abortive, symptom-controlling and prophylactic, and nonpharmacologic treatments. Expert microsurgeons reviewed the data to provide recommendations for optimized patient care. RESULTS Triptans and other ergot derivatives demonstrated strong evidence of vasoconstriction and were greatly advised against for immediate postmicrosurgical use. Novel pharmaceutical therapies such as lasmiditan and calcitonin gene-related peptide antagonists have no literature indicating potential for vasoconstriction or hematoma and remain an investigational option for abortive medical treatment. For symptom control, acetaminophen appears the safest option, with clinical judgment and further research needed for use of nonsteroidal antiinflammatory drugs. Alternative treatment techniques may include migraine prophylaxis with botulinum toxin injection or nutraceutical treatment by means of magnesium supplementation or coenzyme Q10 administration, minimizing the need for additional medication in the postoperative setting. CONCLUSIONS Patients undergoing reconstructive microsurgery have a unique medical profile limiting the therapeutic options available to treat migraines. This review provides preliminary evidence to be considered as a guide for prescribing therapeutics for migraine in the postoperative setting.

Abstract
A vascular anastomosis is a critical surgical skill that involves connecting blood vessels. Traditional handsewn techniques can be challenging and resource intensive. To address these issues, we have developed a unique sutureless anastomotic device called Vaso-Lock. This intraluminal device connects free vascular ends using anchors to maintain traction and enable a rapid anastomosis. We tested the anastomotic capability of Vaso-Locks in a pig common carotid-internal jugular arteriovenous model. The use of Vaso-Lock allowed us to accomplish this procedure in less than 10 min, in contrast to the approximately 40 min required for a handsewn anastomosis. The Vaso-Lock effectively maintained patency for at least 6 weeks without causing significant tissue damage. Histological analysis revealed that the device was successfully incorporated into the arterial wall, promoting a natural healing process. Additionally, organ evaluations indicated no adverse effects from using the Vaso-Lock. Our findings support the safety and effectiveness of the Vaso-Lock for arteriovenous anastomosis in pigs, with potential applicability for translation to humans. Our novel sutureless device has the potential to advance surgical practice and improve patient outcomes.

Abstract
BACKGROUND Recent literature has established outpatient breast reconstruction (BR) to be a safe alternative to inpatient BR. However, the impact of race and ethnicity on BR patient decision-making and postsurgical outcomes remains unexplored. This study aims to assess the impact of race and ethnicity on outpatient BR timing and postoperative complication rates. METHODS The 2013-2020 ACS-NSQIP database was utilized to identify women undergoing outpatient BR. Propensity score-matched analysis was conducted to generate balanced cohorts based on race and ethnicity. t-tests and Fisher's exact tests were used to assess group differences. Logistic regressions were modeled to evaluate differences in complications between groups. RESULTS A total of 63,526 patients underwent outpatient BR. After propensity score matching, 7664 patients and 3948 patients were included in the race and ethnicity-based analysis, respectively. There were statistically significant differences in the timing of BR patients received across cohorts. NW patients had lower rates of immediate BR (IBR) compared with White patients (47% vs. 53%, p < 0.001), and this also was seen in Hispanic patients (97% vs. 3%, p = 0.018). Subsequently, there were higher rates of delayed BR (DBR) in the NW cohort (55% vs. 45%, p < 0.001) and in the Hispanic cohort (95% vs. 5%, p = 0.018). There were no significant differences in the rates of 30-day postoperative complications across cohorts. CONCLUSIONS Ultimately, our findings suggest that minority patients are more likely to undergo DBR than nonminority patients. However, there were no differences in 30-day postoperative outcomes across race or ethnicity. Future studies to elucidate patients' decision-making process in choosing optimal BR types and timing are necessary to better understand the impact of the observed differences in patient care.

Abstract
BACKGROUND This study aims to pioneer in evaluating women's representation in plastic surgery innovations, focusing on mammary prosthesis devices' inventorship. Despite growing gender parity in the field, women's involvement in innovation remains underexplored. This is especially crucial, as the predominant recipients of these innovative technologies are women, urging a necessity for broader female engagement in pioneering surgical advancements. METHOD Patents under the "A61F2/12: Mammary prostheses and implants" classification between the dates January 1, 2011, to December 31, 2020, were identified using Google Patents Advanced. Inclusion criteria included patents (not designs) in English and applications (not grants), with no litigation limitations. Data collected included ID, title, assignee (categorized as industry, academic, private, individual), inventors, and dates (priority, filing, and publication). Sex of inventors was identified with the literature validated gender API, with manual resolution of unresolved genders or with ga_accuracy scores of less than 75%. Data were analyzed using 2-tailed Student t tests, χ2 analysis, and Pearson correlation coefficient (significance set at P ≤ 0.05). RESULTS Of the more than 130,000 plastic surgery patents in English identified between the 10-year period, 1355 were classified as A61F2/12. A total of 374 unique patents were included for analysis (841 duplicates were removed, and 140 patents were excluded because of non-English character author names). There was a significant increase in patents over the decade (from 15 in 2011 to 88 in 2020, R2 = 0.74, P < 0.05), with a decrease in number of inventors per patent (R2 = 0.12, P < 0.05). Of the 1102 total inventors, 138 were female (11.2%), with a 4-fold increase in representation over the decade (R2 = 0.58, P < 0.05), including increase in patents filed with a woman first inventor (0%-14.8%). Women were equally likely to be first 3 inventors versus middle to last inventors (12.8% vs 11.1%, respectively). CONCLUSIONS Over a decade, mammary device innovations rose significantly. Although women inventors' representation improved, it remains disproportionate compared with women in residency/practice. Hence, interventions should aim to align inventor representation with training ratios, through institutional optimization, reducing gender segmentation, and enhancing funding opportunities.

Abstract
BACKGROUND Online resources are commonly used by patients to obtain information on breast reconstruction. Despite the key role of these resources in patient decision-making, their visual content has not yet been evaluated. This study sought to 1) characterize the presence and content of visual aids in online patient education breast reconstruction resources and 2) determine if the women represented in these visual aids reflect the breast reconstruction patient population in the United States. METHODS The top 10 Google websites and the first 400 Google Images containing photographs/graphics depicting human skin for the search phrase "breast reconstruction" were analyzed. Images were categorized by content as "Before/After," "Surgical/Anatomical," "Step-by-Step," or "Breast-Centric Stock Images." Image subjects were classified by skin tone into "White" or "Non-White" using the Fitzpatrick scale and by body type into "Lean" or "Full-Figured." RESULTS In total, 471 images were analyzed. These were predominantly "Before/After" images (43.9%), followed by "Breast-Centric Stock Images" (27.4%), "Surgical/Anatomical" (24.2%), and "Step-by-Step" (4.5%). The majority of all images depicted "White" skin types (90.7%) and "Lean" body types (73.0%). "Before/After" images were more likely to show "Full-Figured" women than the other content categories (p < 0.0001) and had the highest percentage of "Non-White" skin types (35.3%). CONCLUSIONS Our findings demonstrate that breast reconstruction online resources are not reflective of the patient population seeking reconstruction. Improving the diversity of online image resources can both better represent our diverse patient population as well as better align patient expectations with postoperative outcomes, likely improving patient satisfaction.

Abstract
INTRODUCTION Vascular reconstruction requires technical expertise and is often time consuming. As a novel alternative to traditional hand-sewn vascular anastomoses, the VasoLock (VL), is a nonabsorbable, sutureless anastomosis device with traction anchors designed to hold free artery ends together. These anchors do not penetrate the vessel wall but adhere by leveraging the elasticity of the vessels to fasten blood vessels together. This pilot study assesses the performance and patency of this novel device in a porcine model of femoral artery injury. METHODS Female swine (n = 7) underwent femoral artery exposure for a total of 10 VL implanted. Study animals underwent hemodilution to a target hematocrit of 15% and ROTEM was used to assess coagulopathy, followed by an arterial injury via transection. The VL was inserted without any sutures. Flow-probe monitors were positioned proximal and distal to the device and flow rates were measured continuously for a total of 90 min. Flow was analyzed and presented as a ratio of distal to proximal flow with the slope of this ratio across time subsequently determined. Angiographic assessment was completed to evaluate for patency and technical complications after 90 min of implant. RESULTS The average animal weight was 44.1 ± 3.2 kg. The average mean arterial pressure at the time of implant was 51.2 ± 7.8 mmHg, median heart rate was 77.4 (IQR = 77.25-157.4) beats per minute, and average temperature was 36.1 ± 1.5°C. The baseline hematocrit was 13.5 ± 3.0%, average pH was 7.20 ± 0.1, average clotting time was 154.1 ± 58.7 s and average clot formation time was 103.4 ± 10.9 s all demonstrating the acidotic, hypothermic, and coagulopathic state of the swine at the time of insertion. During the 90-min observation period, the average flow gradient identified across the VL was 0.99 ± 0.24, indicating no significant change in flow across the VL. The average slope of the gradients was 0.0005 (P = 0.22), suggesting the ratio of proximal and distal flow did not change over the 90 min. Following 90 min of dwell time, all VL were patent without technical complication. Angiographic assessment at 90 min demonstrated no evidence of dissection, device migration, arterial extravasation, or thromboembolism with any of the 10 devices. CONCLUSIONS This pilot study demonstrated technical feasibility of the novel VL device over a 90-min observation period. All VL were patent and no negative events or complications were identified. This technology demonstrated significant promise in a coagulopathic state: additional investigation, involving long-term survival, is warranted for further validation.

Abstract
BACKGROUND Successful intraoperative microvascular anastomoses are essential for deep inferior epigastric perforator (DIEP) flap survival. This study identifies factors associated with anastomotic failure during DIEP flap reconstruction and analyzes the impact of these anastomotic failures on postoperative patient outcomes and surgical costs. METHODS A retrospective cohort study was conducted of patients undergoing DIEP flap reconstruction at two high-volume tertiary care centers from January 2017 to December 2020. Patient demographics, intraoperative management, anastomotic technique, and postoperative outcomes were collected. Data were analyzed using Student's t-tests, Chi-square analysis, and multivariate logistic regression. RESULTS Of the 270 patients included in our study (mean age 52, majority Caucasian [74.5%]), intraoperative anastomotic failure occurred in 26 (9.6%) patients. Increased number of circulating nurses increased risk of anastomotic failure (odds ratio [OR] 1.02, 95% confidence Interval [CI] 1.00-1.03, p <0.05). Presence of a junior resident also increased risk of anastomotic failure (OR 2.42, 95% CI 1.01-6.34, p <0.05). Increased surgeon years in practice was associated with decreased failures (OR 0.12, CI 0.02-0.60, p <0.05). Intraoperative anastomotic failure increased the odds of postoperative hematoma (OR 8.85, CI 1.35-59.1, p <0.05) and was associated with longer operating room times (bilateral DIEP: 2.25 hours longer, p <0.05), longer hospital stays (2.2 days longer, p <0.05), and higher total operating room cost ($28,529.50 vs. $37,272.80, p <0.05). CONCLUSION Intraoperative anastomotic failures during DIEP flap reconstruction are associated with longer, more expensive cases and increased rates of postoperative complications. Presence of increased numbers of circulators and junior residents was associated with increased risk of anastomotic failure. Future research is necessary to develop practice guidelines for optimizing patient and surgical factors for intraoperative anastomotic success.

Abstract
BACKGROUND There has been an increasing focus on gender disparities in the medical field and in the field of vascular surgery specifically. We aimed to characterize gender representation in vascular surgery innovation over the past 10 years, using metrics of patents and National Institutes of Health (NIH) support. METHODS We performed a retrospective review of all vascular-related patent filings (Google Scholar) and NIH-funded grants (NIH RePORTER) over a 10-year period (January 1st, 2012, to December 31st, 2021). Gender-API (Application Programming Interface) was used to identify the gender of the inventors, with manual confirmation of a 10% random sample. Gender representation for patent inventors and grant principal investigators (PIs) were compared using Chi-squared and Student's t-tests as appropriate. Yearly temporal changes in representation were analyzed using Wilcoxon signed-rank tests and linear regression analyses. RESULTS We identified 2,992 unique vascular device patents with 6,093 associated inventors over 10 years. Women were underrepresented in patent authorship overall (11.5%), and were least likely to be listed as first inventor (8.9%) and most commonly fourth and fifth inventors (15.5% and 14.1%, respectively) compared to men. There was no significant change in representation of women inventors over time (-0.2% females per year, 95% confidence interval (CI) -0.54 to 0.10). We identified 1736 total unique NIH grants, with 23.8% of funded projects having women PIs. There was an increase in the proportion of women PIs over time (+1.31% per year, 95% CI 0.784 to 1.855; P < 0.001). Projects with women PIs received mean total awards that were significantly lower than projects with men PIs ($350,485 ± $220,072 vs. $451,493 ± $411,040; P < 0.001), but the overall ratio of funding:women investigators improved over time (+$11,531 per year, 95% CI $6,167 to $16,895; P = 0.0011). CONCLUSIONS While we have made strides in increasing the number of women in the surgical research space, there is still room for improvement in funding parity. In addition, we found substantial and persistent room for improvement in representation of women in surgical innovation. As we enter a new frontier of surgery hallmarked by equalizing gender representation, these data should serve as a call-to-action for initiative aimed at rebuilding the foundation of surgical innovations upon equal gender representation.

Abstract
Study Design Survey study. Objective Facial vascularized composite allotransplantation (FVCA) can cost over 1 million dollars per procedure and is usually not covered by insurance, yet this financial burden and public opinion surrounding this procedure are not well understood. This study is the first to evaluate the layperson's opinions on the allocation of financial responsibility for FVCA and its inclusion in organ donation registries. Methods Eight hundred and fifteen laypersons were surveyed through MTurk to assess their agreement with 11 statements about FVCA perceptions, funding, and inclusion on organ donation registries. Responses were analyzed with the Wilcoxon Signed-Rank test, the Kruskal-Wallis test, and the Dunn's test. Results The majority of respondents were supportive of FVCA in 10 out of 11 statements (P < 0.0001). They would be willing to undergo FVCA if they suffered from facial disfigurement; believe FVCA is as important as other organ transplants; believe faces should be included on the organ donation registry; support insurance companies providing coverage for FVCA regardless of trauma etiology; support tax dollars funding the procedure; and believe FVCA improves physical appearance and quality of life. Although respondents generally supported their tax dollars funding the procedure, fewer supported this for self-inflicted trauma (P > 0.01). Conclusions This study highlights a disconnect between public preference for insurance coverage of FVCA and current lack of coverage in practice. Respondents' acceptance of including faces in organ donation registries may help alleviate the issue of locating a donor, and increasing financial coverage may broaden this procedure's accessibility to a wider range of individuals.

Abstract
Abstract
Background
Mechanical ventilators are essential to patients who become critically ill with acute respiratory distress syndrome (ARDS), and shortages have been reported due to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Methods
We utilized 3D printing (3DP) technology to rapidly prototype and test critical components for a novel ventilator multiplexer system, Vent-Lock, to split one ventilator or anesthesia gas machine between two patients. FloRest, a novel 3DP flow restrictor, provides clinicians control of tidal volumes and positive end expiratory pressure (PEEP), using the 3DP manometer adaptor to monitor pressures. We tested the ventilator splitter circuit in simulation centers between artificial lungs and used an anesthesia gas machine to successfully ventilate two swine.
Results
As one of the first studies to demonstrate splitting one anesthesia gas machine between two swine, we present proof-of-concept of a de novo, closed, multiplexing system, with flow restriction for potential individualized patient therapy.
Conclusions
While possible, due to the complexity, need for experienced operators, and associated risks, ventilator multiplexing should only be reserved for urgent situations with no other alternatives. Our report underscores the initial design and engineering considerations required for rapid medical device prototyping via 3D printing in limited resource environments, including considerations for design, material selection, production, and distribution. We note that optimization of engineering may minimize 3D printing production risks but may not address the inherent risks of the device or change its indications. Thus, our case report provides insights to inform future rapid prototyping of medical devices.

Abstract
BACKGROUND One of the best methods for protection against respiratory diseases is the use of an N95 mask. Supply shortages have demonstrated a significant need for effective alternatives to N95 masks. Benefits of 3D-printed respirators over N95s include reduced cost and ease of production, widespread availability, reusability/sterilizability, and customizability. 3D-printed mask designs have been downloaded thousands of times; however, there is little to no data on the efficacy of these potential alternatives. METHODS Three of the most popular 3D-printed respirator designs were modified to allow for the Occupational Safety and Health Administration (OSHA) quantitative fit testing that disperses saline into the ambient air and determines concentrations within the mask during multiple trials. Five volunteers conducted standardized fit tests of these masks, as well as an N95 and a KN95, and the results were compared. RESULTS One of the 3D-printed respirators, low poly COVID-19 face mask respirator (mask 2), achieved a fit factor greater than 100 in every trial, representing sufficient fit according to OSHA protocols. The N95 mask achieved a sufficient fit in 60% of the trials, and none of the remaining masks provided a suitable fit factor reliably according to the OSHA fit test. Further trials showed no change in fit factor when different 3D-printable plastics are used or when a widely available high efficiency particulate air (HEPA) filter was used. CONCLUSION 3D-printed respirators provide a possible alternative to N95 masks to protect against respiratory pathogens such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Fit testing results demonstrate that certain 3D-printed mask designs may exceed the fit of N95 masks.

Abstract
BACKGROUND Microsurgery is a foundational plastic surgery principle. However, public unawareness of microsurgery and its associated rigorous training in the USA, may contribute to current misconceptions and undervaluing of plastic and reconstructive surgeons (PRS). This study aims to characterize public knowledge of microsurgery. METHODS A cross-sectional survey was conducted from August to September 2021 using Amazon Mechanical Turk to assess baseline public knowledge of microsurgery. A multivariable logistic regression model was constructed to evaluate the association between baseline knowledge and demographic characteristics. Significance was set to a p<0.05. RESULTS A total of 516 responses were analyzed. The mean age was 36.7 SD 16.04 years (White 84%, and non-Hispanic 70%). Of those surveyed, 52% agreed that general surgeons perform microsurgery, while only 28% agreed that PRS perform microsurgery. When asked if head and neck reconstruction, breast reconstruction, and finger replantation required microsurgery, only 28%, 41%, and 41% of respondents agreed, respectively. When controlled for sociodemographic factors, Hispanics had significantly more odds to mistake that head and neck reconstruction did not require microsurgery (OR 0.49, 0.30-0.80, p 0.004) and less odds to consider PRS for reconstruction (OR 0.51, 0.32-0.84, p 0.008). Females had 1.63 more odds of considering PRS for reconstruction (1.09-2.43 p 0.017). Low-educated subjects had significantly more odds to consider general surgeons as those who performed reconstructive microsurgery (OR 8.70, 1.09-69.40, p 0.041) Conclusions: Misconceptions of microsurgery as a foundational principle of plastic surgery persist and correlate with undervaluing the specialty. Knowledge differs by ethnicity, level of education, and gender. Therefore, patient counseling should use culturally appropriate elements to demystify microsurgery, build value, and better inform risks and benefits.

Abstract
Purpose During the COVID-19 pandemic, virtual events led by residency programs have eased deficits formed by the lack of in-person opportunities. Despite their anecdotal success, there is yet a study on their utility and value, as perceived by attendees. Therefore, we sought to investigate engagement rates of virtual opportunity posts via Instagram, equipping residency programs with recommendations for future virtual event planning. Methods The 40 PRS residency programs with the highest number of followers on Instagram were inspected for posts regarding virtual opportunities. The virtual opportunities were classified by type, medium, and intended audience. The number of opportunities within each classification was analyzed, along with the like/comment to follower ratios, and compared via ANOVA tests. Results A total of 141 virtual opportunities were evaluated, with the most events occurring in August (21.6%). The highest engagement rates occurred in May and June, with the most common virtual opportunity being meet and greets with residents (39.2%). The most prevalent medium for virtual events was Zoom, used in 84.7% of events. The intended audience was frequently medical students (80.6%), with a significant difference in engagement between audience groups (p < 0.05). Conclusion The pandemic has disrupted the status quo of resident recruitment. In light of these findings, residency programs should consider instilling virtual opportunities for medical students as a standard practice. Peak times to broadcast events are May or June due to higher engagement. To address attendee burnout, programs should limit events to familiar ones, such as Zoom meet and greets with residents.

Abstract
Background Caregivers provide critical support for patients with chronic diseases, including heart disease, but often experience caregiver stress that negatively impacts their health, quality of life, and patient outcomes. We aimed to inform health care teams on an evidence‐based approach to supporting the caregivers of patients with heart disease. Methods and Results We conducted a systematic review and meta‐analysis of randomized controlled trials written in English that evaluated interventions to support caregivers of patients with heart disease. We identified 15,561 articles as of April 2, 2020 from 6 databases; of which 20 unique randomized controlled trials were evaluated, representing a total of 1570 patients and 1776 caregivers. Most interventions focused on improving quality of life, and reducing burden, depression, and anxiety; 85% (17 of 20) of the randomized controlled trials provided psychoeducation for caregivers. Interventions had mixed results, with moderate non‐significant effects observed for depression (Hedges’ g=−0.64; 95% CI, −1.34 to 0.06) and burden (Hedges’ g=−0.51; 95% CI, −2.71 to 1.70) at 2 to 4 months postintervention and small non‐significant effects observed for quality of life and anxiety. These results were limited by the heterogeneity of outcome measures and intervention delivery methods. A qualitative synthesis of major themes of the interventions resulted in clinical recommendations represented with the acronym “CARE” (Caregiver‐Centered, Active engagement, Reinforcement, Education). Conclusions This systematic review highlights the need for greater understanding of the challenges faced by caregivers and the development of guidelines to help clinicians address those challenges. More research is necessary to develop clinical interventions that consistently improve caregiver outcomes.

Abstract
Vascular anastomoses typically involve a handsewn technique requiring significant surgical training, expertise, and time. The aim of our systematic review was to identify and describe sutureless vascular anastomosis techniques. We performed a systematic review of all sutureless vascular anastomosis technologies published in MEDLINE, PubMed, Embase, CINAHL, Cochrane, Web of Science, and Scopus Library databases and a patent review using US Patent and Trade Office Application, US Patent and Trademark Office Patent, Google Patents, Lens, Patent Quality Through Artificial Intelligence, SureChEMBL, and E-Space Net. Data from inclusion studies and patents published between January 1, 1980 and July 15, 2021 were abstracted to describe their category, anastomosis type and configuration, study types, and advantages and disadvantages encountered with each technology. Two hundred eleven original studies and 475 patents describing sutureless vascular anastomosis technologies were identified. In the literature, stents/stent-grafts/grafts (n = 61), lasers (n = 53), and couplers (n = 27) were the predominant device categories. In the patent review, adhesive technologies (n = 103), stents/stent-grafts/grafts (n = 68), and mechanical connectors (n = 61) predominated. The majority of studies involved in vivo animal studies (n = 193); 32.2% (n = 68) of investigations involved human trials; and 17.9% (n = 85) of patent technologies were approved by the US Food and Drug Administration. The main advantages described for sutureless anastomosis technologies included faster procedure time and greater patency rates compared with handsewn anastomoses. The main disadvantages included reduced vessel compliance, stenosis, leakage, and device costs. The appeal of sutureless technology is substantiated by numerous animal trials, but their use in humans remains limited. This may be a reflection of strict regulatory criteria and/or vascular complications associated with currently available technologies.

Abstract
BACKGROUND Acute myocardial infarction (AMI) is a common cause of hospital admissions, readmissions, and mortality worldwide. Digital health interventions (DHIs) that promote self-management, adherence to guideline-directed therapy, and cardiovascular risk reduction may improve health outcomes in this population. The "Corrie" DHI consists of a smartphone application, smartwatch, and wireless blood pressure monitor to support medication tracking, education, vital signs monitoring, and care coordination. We aimed to assess the cost-effectiveness of this DHI plus standard of care in reducing 30-day readmissions among AMI patients in comparison to standard of care alone. METHODS A Markov model was used to explore cost-effectiveness from the hospital perspective. The time horizon of the analysis was 1 year, with 30-day cycles, using inflation-adjusted cost data with no discount rate. Currencies were quantified in US dollars, and effectiveness was measured in quality-adjusted life-years (QALYs). The results were interpreted as an incremental cost-effectiveness ratio at a threshold of $100,000 per QALY. Univariate sensitivity and multivariate probabilistic sensitivity analyses tested model uncertainty. RESULTS The DHI reduced costs and increased QALYs on average, dominating standard of care in 99.7% of simulations in the probabilistic analysis. Based on the assumption that the DHI costs $2750 per patient, use of the DHI leads to a cost-savings of $7274 per patient compared with standard of care alone. CONCLUSIONS Our results demonstrate that this DHI is cost-saving through the reduction of risk for all-cause readmission following AMI. DHIs that promote improved adherence with guideline-based health care can reduce hospital readmissions and associated costs.

Abstract
BACKGROUND Uterine allotransplantation (UTx) is a novel therapy to allow women with uterine factor infertility (UFI) to bear their own children. To date, over 60 UTx have been performed, resulting in 15 live births. Our study investigates the attitudes, perspectives, and interests of women with UFI towards UTx. METHODS Anonymous questionnaires were distributed electronically to women diagnosed with UFI at Johns Hopkins Hospital between the years 2003 and 2018. RESULTS Thirty-one women with UFI were identified, resulting in 10 completed surveys. The average age was 31.7 ± 6.31 years, and the average age of diagnosis was 20 years (range 14-31); all 10 surveyed women had congenital UFI. Of note, 80% of women agreed that UTx should be an option for women with UFI, and 90% would consider receiving a UTx. The majority of the nine (90%) women who had previously heard of UTx learned about it from the news (5, 50%). When asked to rank the risks related to UTx in order of personal importance, only two women ranked themselves most important; the other woman ranked fetus and donor as more important. All women had health insurance (70% had private insurance), and 90% believed that UTx should be covered by health insurance. CONCLUSIONS We surveyed women with UFI and found that the majority are willing to have UTx, despite the associated risks of the procedure. Taking into consideration the responses for ranking the importance of risks of the procedure, women with UFI should be considered a vulnerable population, requiring special considerations for UTx informed consents.

Abstract
Background Using mobile health, vital signs such as heart rate (HR) can be used to assess a patient’s recovery process from acute events including acute myocardial infarction (AMI). Objective We aimed to characterize clinical correlates associated with HR change in the subacute period among patients recovering from AMI. Methods HR measurements were collected from 91 patients (4447 HR recordings) enrolled in the MiCORE study using the Apple Watch and Corrie smartphone application. Mixed regression models were used to estimate the associations of patient-level characteristics during hospital admission with HR changes over 30 days postdischarge. Results The mean daily HR at admission was 78.0 beats per minute (bpm) (95% confidence interval 76.1 to 79.8), declining 0.2 bpm/day (-0.3 to -0.1) under a linear model of HR change. History of coronary artery bypass graft, history of depression, or being discharged on anticoagulants was associated with a higher admission HR. Having a history of hypertension, type 2 diabetes mellitus (T2DM), or hyperlipidemia was associated with a slower decrease in HR over time, but not with HR during admission. Conclusion While a declining HR was observed in AMI patients over 30 days postdischarge, patients with hypertension, T2DM, or hyperlipidemia showed a slower decrease in HR relative to their counterparts. This study demonstrates the feasibility of using wearables to model the recovery process of patients with AMI and represents a first step in helping pinpoint patients vulnerable to decompensation.

Abstract
BACKGROUND Benchtop microsurgical training models that use digital tools (smartphones, tablets, and virtual reality [VR]) for magnification are allowing trainees to practice without operating microscopes. This systematic review identifies existing microscope-free training models, compares models in their ability to enhance microsurgical skills, and presents a step-by-step protocol for surgeons seeking to assemble their own microsurgery training model. METHODS We queried PubMed, Embase, and Web of Science databases through November 2020 for microsurgery training models and performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We collected data including training model characteristics (cost, magnification, and components) and outcomes (trainee satisfaction, image resolution, and faster suturing speed). We also conducted a complimentary Google search to identify commercially available microscope-free microsurgical training models or kits not reported in peer-reviewed literature. RESULTS Literature search identified 1,805 publications; 24 of these met inclusion criteria. Magnification tools most commonly included smartphones (n = 10), VR simulators (n = 4), and tablets (n = 3), with magnification ranging up to ×250 magnification on digital microscopy, ×50 on smartphones, and ×5 on tablets. Average cost of training models ranged from $13 (magnification lens) to $15,000 (augmented reality model). Model were formally assessed using workshops with trainees or attendings (n = 10), surveys to end-users (n = 5), and single-user training (n = 4); users-reported satisfaction with training models and demonstrated faster suturing speed and increased suturing quality with model training. Five commercially available microsurgery training models were identified through Google search. CONCLUSION Benchtop microsurgery trainers using digital magnification successfully provide trainees with increased ease of microsurgery training. Low-cost yet high magnification setups using digital microscopes and smartphones are optimal for trainees to improve microsurgical skills. Our assembly protocol, "1, 2, 3, Microsurgery," provides instructions for training model set up to fit the unique needs of any microsurgery trainee.

Abstract
BACKGROUND Thirty-day readmissions among patients with acute myocardial infarction (AMI) contribute to the US health care burden of preventable complications and costs. Digital health interventions (DHIs) may improve patient health care self-management and outcomes. We aimed to determine if patients with AMI using a DHI have lower 30-day unplanned all-cause readmissions than a historical control. METHODS This nonrandomized controlled trial with a historical control, conducted at 4 US hospitals from 2015 to 2019, included 1064 patients with AMI (DHI n=200, control n=864). The DHI integrated a smartphone application, smartwatch, and blood pressure monitor to support guideline-directed care during hospitalization and through 30-days post-discharge via (1) medication reminders, (2) vital sign and activity tracking, (3) education, and (4) outpatient care coordination. The Patient Activation Measure assessed patient knowledge, skills, and confidence for health care self-management. All-cause 30-day readmissions were measured through administrative databases. Propensity score-adjusted Cox proportional hazard models estimated hazard ratios of readmission for the DHI group relative to the control group. RESULTS Following propensity score adjustment, baseline characteristics were well-balanced between the DHI versus control patients (standardized differences <0.07), including a mean age of 59.3 versus 60.1 years, 30% versus 29% Women, 70% versus 70% White, 54% versus 54% with private insurance, 61% versus 60% patients with a non ST-elevation myocardial infarction, and 15% versus 15% with high comorbidity burden. DHI patients were predominantly in the highest levels of patient activation for health care self-management (mean score 71.7±16.6 at 30 days). The DHI group had fewer all-cause 30-day readmissions than the control group (6.5% versus 16.8%, respectively). Adjusting for hospital site and a propensity score inclusive of age, sex, race, AMI type, comorbidities, and 6 additional confounding factors, the DHI group had a 52% lower risk for all-cause 30-day readmissions (hazard ratio, 0.48 [95% CI, 0.26-0.88]). Similar results were obtained in a sensitivity analysis employing propensity matching. CONCLUSIONS Our results suggest that in patients with AMI, the DHI may be associated with high patient activation for health care self-management and lower risk of all-cause unplanned 30-day readmissions.

Abstract
BACKGROUND In 2018, the Northeastern Society of Plastic Surgeons first Women in Plastic Surgery was established, reflecting the national trend to address the gender gap between men and women in surgery. Conferences, such as the annual NESPS, are important opportunities to increase visibility of female role models and resources to address deterrents to surgical careers. We thus sought to examine the participation and visibility of women in the NESPS over the last decade. METHODS Abstracts and programs from the NESPS regional conferences between 2013 and 2019 were accessed via the publicly available past meetings archives, and registration lists were provided by the NESPS. Registrants, panelists, speakers, moderators, and first author and senior author listed for each poster presentation, podium presentation was listed, sex was determined (male or female), and sex were aggregated by category of participation. Significance was set at a P value of less than 0.05. RESULTS Registration of women for the NESPS annual conferences was constant for 5 years (2013-2017), followed by an increase in female registrants from 27.1% in 2017 to 42.3% in 2019. Female representation among poster and podium presentations also increased from 2017 to 2019 (7.7%-23.3% poster presentations and 11.1%-23.4% podium presentations). Invited positions (speakers, panelists, and moderators) had a peak of 32.2% in 2017, but otherwise, there is no clear evidence of improved representation of women. CONCLUSIONS We found an increase in the proportion of female registrants at the annual NESPS conferences from 2013 to 2019. However, visibility of female participants fluctuated over the same period; addressing this represents one opportunity for closing the gender gap at the NESPS. As the percentage of female trainees continues to rise, we look to female faculty to continue to participate in educational events, such as the NESPS meeting, and to be present as role models for the growing new generation of female plastic surgeons.

Abstract
IMPORTANCE In recent years, casual physician attire (fleece jackets and softshell jackets) has become increasingly popular, but to our knowledge, public perceptions of these garments have not been studied. Furthermore, gender biases may result in differing expectations and perceptions of female and male physicians and may be associated with patient rapport and trust building. OBJECTIVE To characterize public perceptions of casual physician attire and implicit gender biases in public assessment of physicians' professional attire. DESIGN, SETTING, AND PARTICIPANTS This survey study used a population-based survey administered via Amazon Mechanical Turk from May to June 2020 among individuals aged 18 years or older who were US residents and for whom English was the primary language. INTERVENTION Survey featuring photographs of a male or female model wearing various types of physician attire (white coat, business attire, and scrubs). MAIN OUTCOMES AND MEASURES Respondents' ratings of professionalism, experience, and friendliness of the male and female models in various attire and perceptions of the models' most likely health care profession. Preference scores for various outfits were calculated as the difference between the preference score for an outfit and the mean preference score for the outfit-role pairing. RESULTS Of 522 surveys completed, 487 were included for analysis; the mean (SD) age of respondents was 36.2 (12.4) years, 260 (53.4%) were female, and 372 (76.4%) were White individuals. Respondents perceived models of health care professionals wearing white coats vs those wearing fleece or softshell jackets as significantly more experienced (mean [SD] experience score: white coat, 4.9 [1.5]; fleece, 3.1 [1.5]; softshell, 3.1 [1.5]; P < .001) and professional (mean [SD] professionalism score: white coat, 4.9 [1.6]; fleece, 3.2 [1.5]; softshell, 3.3 [1.5]; P < .001). A white coat with scrubs attire was most preferred for surgeons (mean [SD] preference index: 1.3 [2.3]), whereas a white coat with business attire was preferred for family physicians and dermatologists (mean [SD] preference indexes, 1.6 [2.3] and 1.2 [2.3], respectively; P < .001). Regardless of outerwear, female models in business attire as inner wear were rated as less professional than male counterparts (mean [SD] professionalism score: male, 65.8 [25.4]; female, 56.2 [20.2]; P < .001). Both the male and the female model were identified by the greater number of respondents as a physician or surgeon; however, the female model vs the male model was mistaken by more respondents as a medical technician (39 [8.0] vs 16 [3.3%]; P < .005), physician assistant (56 [11.5%] vs 11 [2.3%]; P < .001), or nurse (161 [33.1%] vs 133 [27.3%]; P = .050). CONCLUSIONS AND RELEVANCE In this survey study, survey respondents rated physicians wearing casual attire as less professional and experienced than those wearing a white coat. Gender biases were found in impressions of professionalism, with female physicians' roles being more frequently misidentified. Understanding disparate public perceptions of physician apparel may inform interventions to address professional role confusion and cumulative career disadvantages for women in medicine.

Abstract
BACKGROUND Physicians are at the forefront of identifying innovative targets to address current medical needs. 3D printing technology has emerged as a state-of-the-art method of prototyping medical devices or producing patient-specific models that is more cost-efficient, with faster turnaround time, in comparison to traditional prototype manufacturing. However, initiating 3D printing projects can be daunting due to the engineering learning curve, including the number of methodologies, variables, and techniques for printing from which to choose. To help address these challenges, we sought to create a guide for physicians interested in venturing into 3D printing. STUDY DESIGN All commercially available, plug-and-play, material and stereolithography printers costing less than $15,000 were identified via web search. Companies were contacted to obtain quotes and information sheets for all printer models. The qualifying printers' manufacturer specification sheets were reviewed, and pertinent variables were extracted. RESULTS We reviewed 309 commercially available printers and materials and identified 118 printers appropriate for clinicians desiring plug-and-play models for accelerated device production. We synthesized this information into a decision-making tool to choose the appropriate parameters based on project goals. CONCLUSIONS There is a growing clinical need for medical devices to reduce costs of care and increase access to personalized treatments; however, the learning curve may be daunting for surgeons. In this review paper, we introduce the "3Ms of 3D printing" for medical professionals and provide tools and data sheets for selection of commercially available, affordable, plug-and-play 3D printers appropriate for surgeons interested in innovation.

Abstract
BACKGROUND Strict social distancing measures owing to the COVID-19 pandemic have led people to rely more heavily on social media, such as Facebook groups, as a means of communication and information sharing. Multiple Facebook groups have been formed by medical professionals, laypeople, and engineering or technical groups to discuss current issues and possible solutions to the current medical crisis. OBJECTIVE This study aimed to characterize Facebook groups formed by laypersons, medical professionals, and technical professionals, with specific focus on information dissemination and requests for crowdsourcing. METHODS Facebook was queried for user-created groups with the keywords "COVID," "Coronavirus," and "SARS-CoV-2" at a single time point on March 31, 2020. The characteristics of each group were recorded, including language, privacy settings, security requirements to attain membership, and membership type. For each membership type, the group with the greatest number of members was selected, and in each of these groups, the top 100 posts were identified using Facebook's algorithm. Each post was categorized and characterized (evidence-based, crowd-sourced, and whether the poster self-identified). STATA (version 13 SE, Stata Corp) was used for statistical analysis. RESULTS Our search yielded 257 COVID-19-related Facebook groups. Majority of the groups (n=229, 89%) were for laypersons, 26 (10%) were for medical professionals, and only 2 (1%) were for technical professionals. The number of members was significantly greater in medical groups (21,215, SD 35,040) than in layperson groups (7623, SD 19,480) (P<.01). Medical groups were significantly more likely to require security checks to attain membership (81% vs 43%; P<.001) and less likely to be public (3 vs 123; P<.001) than layperson groups. Medical groups had the highest user engagement, averaging 502 (SD 633) reactions (P<.01) and 224 (SD 311) comments (P<.01) per post. Medical professionals were more likely to use the Facebook groups for education and information sharing, including academic posts (P<.001), idea sharing (P=.003), resource sharing (P=.02) and professional opinions (P<.001), and requesting for crowdsourcing (P=.003). Layperson groups were more likely to share news (P<.001), humor and motivation (P<.001), and layperson opinions (P<.001). There was no significant difference in the number of evidence-based posts among the groups (P=.10). CONCLUSIONS Medical professionals utilize Facebook groups as a forum to facilitate collective intelligence (CI) and are more likely to use Facebook groups for education and information sharing, including academic posts, idea sharing, resource sharing, and professional opinions, which highlights the power of social media to facilitate CI across geographic distances. Layperson groups were more likely to share news, humor, and motivation, which suggests the utilization of Facebook groups to provide comedic relief as a coping mechanism. Further investigations are necessary to study Facebook groups' roles in facilitating CI, crowdsourcing, education, and community-building.

Abstract
BACKGROUND Persistent public misconceptions of plastic and reconstructive surgery (PRS), ambiguity between cosmetic versus reconstructive surgical procedures, and subjective interpretation of aesthetics can result in undervaluing of the field. Our study analyzes how patient context (cosmetic or reconstructive/restorative cues) affect public perception of outcomes and value of surgery. METHODS We distributed Qualtrics™ surveys to laypersons via Amazon Mechanical Turk. Demographics were self-reported. The survey presented a series of pre- and post-operative photographs of PRS surgeries alongside either a cosmetic or reconstructive/restorative cue, followed by questions on values of procedure. Survey responses were analyzed using two-tailed Student's t tests and chi square analyses, univariate and multivariate analysis, and linear regression. RESULTS Of the 459 respondents, the mean age was 38.5 ± 12.1 years, and was 50.5% (232) male. The majority of respondents classified breast reconstruction as a cosmetic surgery (243, 66.8%), and was rated more attractive (p < 0.0005), higher impact on self-esteem (p < 0.001), and to be covered by health insurance (p < 0.0001) compared to breast augmentation. Reconstructive cued breast and facial procedures were viewed more favorably; the exception was gynecomastia reduction. Reconstructive classification had significant positive correlation with support for insurance coverage (R2 = 0.8268) and willingness to pursue (R2 = 0.5328). CONCLUSIONS This study revealed more public support for reconstructive/restorative cued PRS cases over cosmetic cued PRS cases, and persistent misconceptions of breast reconstruction as a cosmetic procedure. Reconstructive or restorative cues can be used to educate the public and address skewed perceptions on the roles and value of PRS.

Abstract
Background: The COVID-19 pandemic has resulted in unpreceded changes to medical education. Medical students interested in urology and neurosurgery have reported concerns regarding COVID-19’s effects on clinical experience and the residency application process; however, the impact amongst students interested in plastic surgery is unknown. We hypothesized that students applying into plastic surgery may experience much distress as a result of the COVID-19 pandemic. Methods: An electronic survey was developed by 3 plastic surgery residents and 2 academic plastic surgeons and later refined by 4 fourth-year medical students. Questions focused on medical education curricular changes, perceived impact on medical education, and demographics. From April–May 2020 the survey was distributed to medical students who were interested in plastic surgery. Participants were identified through plastic surgery residency program personnel and social media platforms. Results: In total, 130 of the 140 respondents reported interest in plastic surgery careers. An estimated 67% were in their clinical years or completing research year(s) before residency applications. Of the respondents, 80% believed that the COVID-19 pandemic had a negative impact on their medical education. Clinical-level students compared with preclinical-level students, and students applying to residency during the 2020–2021 match cycle compared with students not applying during the 2020–2021 match cycle were significantly more likely to perceive the COVID-19 pandemic as having a negative impact on their medical education (P = 0.04 and 0.03, respectively). Conclusion: Medical students interested in plastic surgery perceive the COVID-19 pandemic as having a negative impact on their education, likely due to a reduction in clinical exposure.

Abstract
Background Cardiovascular disease (CVD) is the leading cause of death worldwide. Despite strong evidence supporting the benefits of cardiac rehabilitation (CR), over 80% of eligible patients do not participate in CR. Digital health technologies (ie, the delivery of care using the internet, wearable devices, and mobile apps) have the potential to address the challenges associated with traditional facility-based CR programs, but little is known about the comprehensiveness of these interventions to serve as digital approaches to CR. Overall, there is a lack of a systematic evaluation of the current literature on digital interventions for CR. Objective The objective of this systematic literature review is to provide an in-depth analysis of the potential of digital health technologies to address the challenges associated with traditional CR. Through this review, we aim to summarize the current literature on digital interventions for CR, identify the key components of CR that have been successfully addressed through digital interventions, and describe the gaps in research that need to be addressed for sustainable and scalable digital CR interventions. Methods Our strategy for identifying the primary literature pertaining to CR with digital solutions (defined as technology employed to deliver remote care beyond the use of the telephone) included a consultation with an expert in the field of digital CR and searches of the PubMed (MEDLINE), Embase, CINAHL, and Cochrane databases for original studies published from January 1990 to October 2018. Results Our search returned 31 eligible studies, of which 22 were randomized controlled trials. The reviewed CR interventions primarily targeted physical activity counseling (31/31, 100%), baseline assessment (30/31, 97%), and exercise training (27/31, 87%). The most commonly used modalities were smartphones or mobile devices (20/31, 65%), web-based portals (18/31, 58%), and email-SMS (11/31, 35%). Approximately one-third of the studies addressed the CR core components of nutrition counseling, psychological management, and weight management. In contrast, less than a third of the studies addressed other CR core components, including the management of lipids, diabetes, smoking cessation, and blood pressure. Conclusions Digital technologies have the potential to increase access and participation in CR by mitigating the challenges associated with traditional, facility-based CR. However, previously evaluated interventions primarily focused on physical activity counseling and exercise training. Thus, further research is required with more comprehensive CR interventions and long-term follow-up to understand the clinical impact of digital interventions.

Abstract
Mobile health (mHealth) interventions have demonstrated promise in improving outcomes by motivating patients to adopt and maintain healthy lifestyle changes as well as improve adherence to guideline-directed medical therapy. Early results combining behavioral economic strategies with mHealth delivery have demonstrated mixed results. In reviewing these studies, we propose that the success of a mHealth intervention links more strongly with how well it connects patients back to routine clinical care, rather than its behavior modification technique in isolation. This underscores the critical role of clinician-patient partnerships in the design and delivery of such interventions, while also raising important questions regarding long-term sustainability and scalability. Further exploration of our hypothesis may increase opportunities for multidisciplinary clinical teams to connect with and engage patients using mHealth technologies in unprecedented ways.

Abstract
Background The American College of Surgeons reports 88,320 intraoperative needlestick injuries (NSIs) per year, resulting in US $376 to US $2456 in costs per NSI. Engineered sharps injury prevention (ESIP) devices protect against NSIs. To our knowledge, no study has been published to date to demonstrate clinical effectiveness of an intraoperative ESIP device. Operative Armour is a wearable arm cuff that can be donned during surgical closure to allow surgeons to keep a suture pack and sharps protection container on their forearm. Objective We characterize Operative Armour’s ESIP device effectiveness in a tertiary hospital, hypothesizing that this device will decrease NSI risk by decreasing behaviors associated with NSIs: needle passing and handling. Methods A prospective case-control study was conducted with institutional review board quality improvement designation in which authors observed skin closures of plastic surgery procedures. To ensure accuracy, one surgeon was observed at a time. Control surgeries were purely observational; intervention cases involved surgeon use of the device during skin closure. Outcomes of interest included needle passing, needle handling, lost needles, and loaded waiting needles. Results Surgeons were observed in 50 control and 50 intervention cases. Operative Armour eliminated needle passing during skin closure. One NSI occurred in one control case; no NSIs were observed in intervention cases (P=.36). The mean number of loaded and unprotected waiting needles was also significantly decreased in the intervention group from 2.3 to 0.2 (P<.001). Furthermore, a multivariable linear regression established that Operative Armour significantly decreased the number of needle adjustments by hand per stitch observed (F4, 21.68=3.72; P=.01). In fact, needle adjustments by hand decreased overall (1 adjustment per 10 stitches vs 1 adjustment per 5 stitches, P=.004), and adjustments occurred half as frequently with use of Operative Armour in free flap reconstruction (1 adjustment per 10 stitches vs 1 adjustment per 5 stitches, P=.03) and a quarter as frequently in other breast reconstruction cases such as mastopexy (1 adjustment per 20 stitches vs 1 adjustment per 5 stitches, P=.002). Conclusions Operative Armour effectively functions as an ESIP device by decreasing intraoperative needle passing and handling. Although sample size prohibits demonstrating a decrease in NSIs during observed cases, by decreasing behaviors that drive NSI risk, we anticipate an associated decrease in NSIs with use of the device.

Abstract
BACKGROUND This study aims to understand how sociodemographic factors influence perceptions of "Brazilian Butt Lift" (BBL), the cosmetic procedure with the highest reported mortality rate, among adult women. We also investigate whether education about risks changes willingness to receive this procedure. METHODS A Qualtrics© survey including education about BBL was administered on Amazon Mechanical Turk, with inclusion criteria of female sex. RESULTS Survey data from 489 female participants were included. 78.1% of participants found the BBL mortality rate to be higher than expected. 70.1% of the original 177 willing or neutral participants became unwilling to undergo a BBL after education. Multivariate logistic regression indicated that individuals who were more willing to undergo BBL after education were individuals who have a diagnosis of body dysmorphic disorder (OR 60.5, p = 0.02) or have an acquaintance who received a BBL (OR 230.2, p < 0.01). CONCLUSIONS Overall, survey participants were less willing to undergo BBL after learning its risks, indicating the critical role of patient education during informed consent. Additionally, individuals who are unhappy with their body shape, or who feel cultural or social pressure to attain a certain body shape, may accept higher levels of risk to improve their looks, suggesting patient motivation for the procedure may limit even the most effective informed consent process. In light of these findings, the surgical community may consider regulating the BBL procedure and improving safety using evidence-based risk reduction techniques. Ensuring that patients fully understand the risks associated with the BBL procedure is critical for both surgeon and patient.

Abstract
BACKGROUND Unplanned readmissions after hospitalization for acute myocardial infarction are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions could be an effective tool in promoting self-management, adherence to guideline-directed therapy, and cardiovascular risk reduction. A digital health intervention developed at Johns Hopkins-the Corrie Health Digital Platform (Corrie)-includes the first cardiology Apple CareKit smartphone application, which is paired with an Apple Watch and iHealth Bluetooth-enabled blood pressure cuff. Corrie targets: (1) self-management of cardiac medications, (2) self-tracking of vital signs, (3) education about cardiovascular disease through articles and animated videos, and (4) care coordination that includes outpatient follow-up appointments. METHODS AND RESULTS The 3 phases of the MiCORE study (Myocardial infarction, Combined-device, Recovery Enhancement) include (1) the development of Corrie, (2) a pilot study to assess the usability and feasibility of Corrie, and (3) a prospective research study to primarily compare time to first readmission within 30 days postdischarge among patients with Corrie to patients in the historical standard of care comparison group. In Phase 2, the feasibility of deploying Corrie in an acute care setting was established among a sample of 60 patients with acute myocardial infarction. Phase 3 is ongoing and patients from 4 hospitals are being enrolled as early as possible during their hospital stay if they are 18 years or older, admitted with acute myocardial infarction (ST-segment-elevation myocardial infarction or type I non-ST-segment-elevation myocardial infarction), and own a smartphone. Patients are either being enrolled with their own personal devices or they are provided an iPhone and/or Apple Watch for the duration of the study. Phase 3 started in October 2017 and we aim to recruit 140 participants. CONCLUSIONS This article will provide an in-depth understanding of the feasibility associated with implementing a digital health intervention in an acute care setting and the potential of Corrie as a self-management tool for acute myocardial infarction recovery.

Abstract
The rate of cardiovascular disease (CVD) mortality reduction in the United States has plateaued recently, despite the development of novel preventive pharmacotherapies, increased access to care, and healthcare spending. This is largely due to American's poor dietary patterns and practices causing increasing trends in the prevalence of obesity and type 2 diabetes mellitus. For decades, dietary guidelines on 'healthy diets' to reduce CVD risk, grounded in epidemiological research, have been nationally distributed to Americans. In this review, we highlight landmark events in modern nutrition science and how these have framed past and current understandings of diet and health. We also follow the evolution of dietary recommendations for Americans throughout the years, with an emphasis on recommendations aimed to reduce risk for CVD and mortality. Secondly, we examine how the low-fat ideology came to dominate America in the last decades of the 20th century and subsequently contributed to an excess intake of refined carbohydrates which, in the context of an increasingly sedentary lifestyle, may have fueled the obesity epidemic. We then examine the current major evidence-based dietary patterns and specific dietary approaches to reduce CVD risk, reviewing the literature surrounding nutritional components of the heart-healthy diet and discussing the dietary patterns proven most effective for CVD prevention: the Dietary Approaches to Stop Hypertension (DASH) diet, the Mediterranean diet, and the healthy vegetarian diet. Finally, we discuss emerging dietary trends, considerations for nutrition counseling, and future directions within the important field of nutrition, with the ultimate goal of improving vascular health.

Abstract
Background As smartphone ownership continues to rise, health care systems and technology companies are driven to develop mobile health (mHealth) interventions as both diagnostic and therapeutic tools. An important consideration during mHealth intervention development is how to achieve health equity despite demographic differences in smartphone ownership. One solution is through the recirculation of loaner smartphones; however, best practices for implementing such programs to optimize security, privacy, scalability, and convenience for participants are not well defined. Objective In this tutorial, we describe how we implemented our novel Corrie iShare program, a 30-day loaner iPhone and smartwatch recirculation program, as part of a multi-center mHealth intervention to improve recovery and access to guideline-directed therapy following acute myocardial infarction. Methods We conducted a prospective study utilizing a smartphone app and leveraged iOS enterprise features as well as cellular data service to automate recirculation. Results Our configuration protocol was shortened from 1 hour to 10 minutes. Of 200 participants, 92 (46.0%) did not own an iPhone and would have been excluded from the study without iShare. Among iShare participants, 72% (66/92) returned their loaned smartphones. Conclusions The Corrie iShare program demonstrates the potential for a sustainable and scalable mHealth loaner program, enabling broader population reach while optimizing user experience. Implementation may face institutional constraints and software limitations. Consideration should be given to optimizing loaner returns.

Abstract
A key metabolic adaptation of some species that face hypoxia as part of their life cycle involves an alternative electron transport chain in which rhodoquinone (RQ) is required for fumarate reduction and ATP production. RQ biosynthesis in bacteria and protists requires ubiquinone (Q) as a precursor. In contrast, Q is not a precursor for RQ biosynthesis in animals such as parasitic helminths, and most details of this pathway have remained elusive. Here, we used Caenorhabditis elegans as a model animal to elucidate key steps in RQ biosynthesis. Using RNAi and a series of C. elegans mutants, we found that arylamine metabolites from the kynurenine pathway are essential precursors for RQ biosynthesis de novo Deletion of kynu-1, encoding a kynureninase that converts l-kynurenine (KYN) to anthranilic acid (AA) and 3-hydroxykynurenine (3HKYN) to 3-hydroxyanthranilic acid (3HAA), completely abolished RQ biosynthesis but did not affect Q levels. Deletion of kmo-1, which encodes a kynurenine 3-monooxygenase that converts KYN to 3HKYN, drastically reduced RQ but not Q levels. Knockdown of the Q biosynthetic genes coq-5 and coq-6 affected both Q and RQ levels, indicating that both biosynthetic pathways share common enzymes. Our study reveals that two pathways for RQ biosynthesis have independently evolved. Unlike in bacteria, where amination is the last step in RQ biosynthesis, in worms the pathway begins with the arylamine precursor AA or 3HAA. Because RQ is absent in mammalian hosts of helminths, inhibition of RQ biosynthesis may have potential utility for targeting parasitic infections that cause important neglected tropical diseases.

Abstract
Treatment of arteriovenous malformations (AVMs) should be individualized based on the imaging findings. A total of 117 AVM cases were categorized into three types based on the angio-architectural characteristics: Type I (n=14, no draining vein or diameter of the draining vein <2mm); Type II (n=64, draining vein diameter 2-6mm); and Type III (n=39, draining vein diameter >6mm). Subjects were randomly allocated to one of two treatment groups: Group A (n=59) received multipoint percutaneous ethanol injection (MPEI), while Group B (n=58) received super-selective angiograms followed by embolization with gelfoam (EFAG) plus MPEI. Patients were followed up for 2-6 years. A significant between-group difference with respect to treatment outcomes was observed only for Type III cases (P<0.05). Direct percutaneous puncture digital-subtraction-angiography-guided classification of AVMs provides easy-to-follow guidelines for its clinical management. EFAG plus MPEI with reduced procedure time and the amount of ethanol should be used for Type III AVMs.

Abstract
Cytotoxic and hemolytic activity of Haemophilus (Actinobacillus) pleuropneumoniae serotype 1 strain CM5 was investigated because of the potential role as a virulence determinant. Viable bacteria were toxic for porcine and bovine neutrophils, whereas bacteria killed by heat treatment at 60 C for 1 hour were not. Similarly, bacteria-free culture supernatant was cytotoxic and hemolytic in assays that used porcine neutrophils and erythrocytes, whereas supernatant treated at 60 C for 1 hour had no activity. Erythrocytes from various species were susceptible to the hemolytic activity of bacteria-free culture supernatant, with ovine and bovine erythrocytes being most sensitive. The neutrophil-toxic and hemolytic activity of bacteria-free culture supernatant was inhibited by cholesterol and oxygen and abolished after trypsin digestion. The neutrophil-toxic and hemolytic activity was preserved during storage at or less than 4 C, but was lost rapidly at 56 C or 80 C. Neutralizing antibodies were demonstrated in serum of pigs and rabbits immunized with 10-fold concentrated culture supernatant of strain CM5 and in field pigs that had recovered from natural infection with H pleuropneumoniae serotype 1. Bacteria-free culture supernatants of 18 strains, including H pleuropneumoniae serotypes 1 through 10, Actinobacillus suis, and Haemophilus taxon minor group, were tested for heat-sensitive, neutrophil-toxic, and hemolytic activity. Fifteen strains were neutrophil toxic, but only 10 of these were hemolytic. Haemophilus pleuropneumoniae, serotype 1, strain VLS557; serotype 5, strain K17; and Haemophilus taxon minor group strain 33PN were neither cytotoxic nor hemolytic.
