RESUMO

BACKGROUND: Health care providers play an important role in the national opioid crisis with 40% of opioid-related deaths being attributed to prescription medications (Centers for Disease Control and Prevention, U.S. Department of Health and Human Services. 2018) and as many as half of the opioid pills prescribed after outpatient plastic surgery may go unused (Plast Reconstr Surg 2019;143:929-938). The purpose of this study was to provide broad foundational data regarding postoperative analgesic prescribing patterns among members of the American Society of Plastic Surgeons (ASPS) to facilitate inclusion of opioid data fields in the ASPS Tracking Operations and Outcomes for Plastic Surgeons database for longitudinal evaluation. METHODS: A survey regarding opioid prescribing practices was electronically distributed to a representative cohort of 2555 ASPS members. Two hundred seventy-nine responses (11% response rate) were received. RESULTS: The majority of respondents reported prescribing opioids following 1 or more types of cosmetic and reconstructive procedures (90.2% and 81.7%, respectively; p = 0.0057), most commonly oxycodone and hydrocodone. Most (61.9%) reported less than 5% of patients request an opioid refill. Nonopioid medications, most commonly acetaminophen and ibuprofen/naproxen, were also prescribed but less commonly so for cosmetic (80.7-85.8%) than reconstructive (86.3-91.5%) procedures. Local anesthetic was less commonly used for mastopexy (83.7%) than augmentation (91.8%, p = 0.02). CONCLUSIONS: Based on survey responses, potential areas of improvement to reduce opioid prescribing and use include provider education on the use of multimodal pain regimens including nonopioid medication and "as needed" rather than scheduled dosing, use of local anesthetic blocks, as well as patient education on opioid safety and proper disposal of unused medication.

RESUMO

C-Glycosylation reactions of glycosyl picolinates with allyltrimethylsilane or silyl enol ethers were developed. Picolinate as a chelation-assisted leaving group could be activated by Cu(OTf)2 and avoided the use of harsh Lewis acids. The glycosylations were operated under mild neutral conditions and gave the corresponding C-glycosides in up to 95% yield with moderate to excellent stereoselectivities.

RESUMO

Glycosyl isoquinoline-1-carboxylate was developed as a novel benchtop stable and readily available glycosyl donor. The glycosylation reaction was promoted by the inexpensive Cu(OTf)2 salt under mild reaction conditions. The copper isoquinoline-1-carboxylate salt was precipitated from the solution and thus rendered a traceless leaving group. Surprisingly, the proton from the acceptor was absorbed by the precipitated metal complex and the reaction mixture remained at neutral pH. The copper-promoted glycosylation was also proven to be completely orthogonal to the gold-promoted glycosylation, and an iterative synthesis of oligosaccharides from benchtop stable anomeric ester building blocks becomes possible under mild reaction conditions.

RESUMO

Polyrotaxanes, a family of rod-shaped nanomaterials comprised of noncovalent polymer/macrocycle assemblies, are being used in a growing number of materials and biomedical applications. Their physiochemical properties can vary widely as a function of composition, potentially leading to different in vivo performance outcomes. We sought to characterize the pharmacokinetic profiles, toxicities, and protein corona compositions of 2-hydroxypropyl-ß-cyclodextrin polyrotaxanes as a function of variations in macrocycle threading efficiency, molecular weight, and triblock copolymer core structure. We show that polyrotaxane fate in vivo is governed by the structure and dynamics of their rodlike morphologies, such that highly threaded polyrotaxanes are long circulating and deposit in the liver, whereas lung deposition and rapid clearance is observed for species bearing lower 2-hydroxypropyl-ß-cyclodextrin threading percentages. Architecture differences also promote recruitment of different serum protein classes and proportions; however, physiochemical differences have little or no influence on their toxicity. These findings provide important structural insights for guiding the development of polyrotaxanes as scaffolds for biomedical applications.

RESUMO

We have developed a versatile synthetic strategy for the synthesis of the natural product diptoindonesin G and its analogues as selective modulators of estrogen receptors. The strategy involves a regioselective dehydrative cyclization of arylacetals, a regioselective bromination of benzofurans, a sequential cross-coupling of bromo-benzofurans with aryl boronic acids, and a BBr3-mediated tandem cyclization and demethylation. Preliminary biological studies uncovered the critical and dispensable phenolic hydroxyl groups in the natural product and also revealed unexpected selectivity for isoforms of estrogen receptor.

RESUMO

BACKGROUND: The National Surgical Quality Improvement Program (NSQIP) and the Tracking Operations and Outcomes for Plastic Surgeons (TOPS) registries gather outcomes for plastic surgery procedures. The NSQIP collects hospital data using trained nurses, and the TOPS relies on self-reported data. We endeavored to compare the TOPS and NSQIP data sets with respect to cohort characteristics and outcomes to better understand the strengths and weakness of each registry as afforded by their distinct data collection methods. STUDY DESIGN: The 2008 to 2011 TOPS and NSQIP databases were queried for breast reductions and breast reconstructions. Propensity score matching identified similar cohorts from the TOPS and NSQIP databases. Shared 30-day surgical and medical complications rates were compared across matched cohorts. RESULTS: The TOPS captured a significantly greater number of wound dehiscence occurrences (4.77%-5.47% vs 0.69%-1.17%, all P<0.001), as well as more reconstructive failures after prosthetic reconstruction (2.82% vs 0.26%, P<0.001). Medical complications were greater in NSQIP (P<0.05). Other complication rates did not differ across any procedure (all P>0.05). CONCLUSIONS: The TOPS and NSQIP capture significantly different patient populations, with TOPS' self-reported data allowing for the inclusion of private practices. This self-reporting limits TOPS' ability to identify medical complications; surgical complications and readmissions, however, were not underreported. Many surgical complications are captured by TOPS at a higher rate due to its broader definitions, and others are not captured by NSQIP at all. The TOPS and NSQIP provide complementary information with different strengths and weakness that together can guide evidence-based decision making in plastic surgery.

RESUMO

BACKGROUND: Combined abdominal and breast surgery presents a convenient and relatively cost-effective approach for accomplishing both procedures. OBJECTIVES: This study is the largest to date assessing the safety of combined procedures, and it aims to develop a simple pretreatment risk stratification method for patients who desire a combined procedure. METHODS: All women undergoing abdominoplasty, panniculectomy, augmentation mammaplasty, and/or mastopexy in the TOPS database were identified. Demographics and outcomes for combined procedures were compared to individual procedures using χ(2) and Student's t-tests. Multiple logistic regression provided adjusted odds ratios for the effect of a combined procedure on 30-day complications. Among combined procedures, a logistic regression model determined point values for pretreatment risk factors including diabetes (1 point), age over 53 (1), obesity (2), and 3+ ASA status (3), creating a 7-point pretreatment risk stratification tool. RESULTS: A total of 58,756 cases met inclusion criteria. Complication rates among combined procedures (9.40%) were greater than those of aesthetic breast surgery (2.66%; P < .001) but did not significantly differ from abdominal procedures (9.75%; P = .530). Nearly 77% of combined cases were classified as low-risk (0 points total) with a 9.78% complication rates. Medium-risk patients (1 to 3 points) had a 16.63% complication rate, and high-risk (4 to 7 points) 38.46%. CONCLUSIONS: Combining abdominal and breast procedures is safe in the majority of patients and does not increase 30-day complications rates. The risk stratification tool can continue to ensure favorable outcomes for patients who may desire a combined surgery. LEVEL OF EVIDENCE: 4 Risk.

RESUMO

Background: Evaluation of practice patterns by American Board of Plastic Surgery (ABPS) diplomates allows for a greater understanding as to how the field is progressing. Understanding evolving procedural trends can give insight into plastic surgeons' subspecialty focus and influence resident training to prepare them for future practice. Methods: American Society of Plastic Surgeons member only projections for aesthetic and reconstructive procedures were reviewed from 1999 to 2018 in 5-year increments to identify shifts in frequency between the beginning (1999-2003) and end (2014-2018) of the timeframe. Tracer utilization for all four ABPS modules were also examined between 2014 and 2018. Descriptive statistics were performed to identify significant changes (P < 0.05) in subspecialty focus and procedure trends. Results: Annual procedure incidence between 2014 and 2018 was compared with that between 1999 and 2003. The annual number of procedures more than doubled from 3,244,084 to 6,628,082. Among reconstructive procedures, there was a statistically significant increase in the number of breast reconstruction, breast implant removal, and maxillofacial surgery procedures, and a statistically significant decrease in the number of procedures focused on reconstruction of birth defects, burn injuries, and hand anomalies. In aesthetic surgery, significant increases were seen in the number of augmentation mammoplasty, abdominoplasty, and mastopexy procedures, with significant decreases in the number of blepharoplasty and rhinoplasty procedures. Conclusions: Understanding the changing practice patterns of ABPS diplomates is essential to define the direction that our specialty is taking over time, and to guide program directors in plastic surgery on areas of focus for appropriate training of plastic surgeons.

RESUMO

BACKGROUND: Hidradenitis suppurativa is a chronic inflammatory dermatologic condition occurring most commonly in areas with large numbers of apocrine sweat glands. Surgical excision and wound reconstruction are indicated for severe or refractory disease. This study aims to explore institutional reconstructive outcomes following hidradenitis suppurativa excision and compare these to the nationally recognized Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database to determine best-practice guidelines. METHODS: A retrospective chart review of all patients with surgically treated hidradenitis suppurativa from January of 2004 to January of 2016 was performed. Data on patient characteristics, reconstructive methods, and outcomes were collected. Outcomes for each reconstructive method were analyzed and associations between reconstruction and complications were determined. These results were compared to TOPS data. RESULTS: A total of 382 operative sites for 101 individual patients were reviewed. Overall complication rates were 80, 68.3, and 59.6 percent for simple, intermediate, and complex closure, respectively; 68.3 percent for adjacent soft-tissue rearrangement; and 100 percent for split-thickness skin grafts and perforator flaps. Statistical significance was identified between superficial wound dehiscence and adjacent tissue rearrangement compared to intermediate and complex closure (p = 0.0132). TOPS data revealed similar wound breakdown rates for primary closure methods but much lower rates with negative-pressure wound therapy, split-thickness skin grafts, and muscle flaps. CONCLUSIONS: Primary closure techniques for hidradenitis suppurativa wound reconstruction possess high complication rates, whereas improved outcomes are observed with negative-pressure wound therapy, split-thickness skin grafts, and muscle flaps. The correlation in outcomes between our experience and that reported in the TOPS database provides a level of validation to this national database.

RESUMO

SUMMARY: The Plastic Surgeries Registry Network supported by the American Society of Plastic Surgeons (ASPS) and the Plastic Surgery Foundation offers a variety of options for procedural data and outcomes assessment and research. The Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database is a registry created for and used by active members of ASPS to monitor all types of procedural outcomes. It functions as a way for individual or group practices to follow surgical outcomes and constitutes a huge research registry available to ASPS members to access for registry-based projects. The TOPS registry was launched in 2002 and has undergone several iterations and improvements over the years and now includes more than 1 million procedure records. Although ASPS member surgeons have proven valuable assets in contributing their data to the TOPS registry, fewer have leveraged the database for registry-based research. This article overviews the authors' experience using the TOPS registry for a database research project to demonstrate the process, usefulness, and accessibility of TOPS data for ASPS member surgeons to conduct registry-based research. This article pairs with the report of the authors' TOPS registry investigation related to 30-day adverse events associated with incision location for augmentation mammaplasty.

RESUMO

A general method has been developed for the formation of glycosyl chlorides and bromides from picolinic esters under mild and neutral conditions. Benchtop stable picolinic esters are activated by a copper(II) halide species to afford the corresponding products in high yields with a traceless leaving group. Rare ß glycosyl chlorides are accessible via this route through neighboring group participation. Additionally, glycosyl chlorides with labile protecting groups previously not easily accessible can be prepared.

RESUMO

A catalytic method is developed for the diastereoselective acylation of the anomeric hydroxyl group in diverse carbohydrates to form either α- or ß-anomeric esters. While exclusive formation of the ß-isomer was observed in most sugar substrates with one enantiomer of the chiral catalyst, moderate to high α-selectivity was obtained by using the other enantiomer of the chiral catalyst. The resulting α- and ß-anomeric esters have very different reactivity toward a reduction reaction.

RESUMO

BACKGROUND: Risk discussion is a central tenet of the dialogue between surgeon and patient. Risk calculators have recently offered a new way to integrate evidence-based practice into the discussion of individualized patient risk and expectation management. Focusing on the comprehensive Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database, we endeavored to add plastic surgical outcomes to the previously developed Breast Reconstruction Risk Assessment (BRA) score. METHODS: The TOPS database from 2008 to 2011 was queried for patients undergoing breast reconstruction. Regression models were constructed for the following complications: seroma, dehiscence, surgical site infection (SSI), explantation, flap failure, reoperation, and overall complications. RESULTS: Of 11,992 cases, 4439 met inclusion criteria. Overall complication rate was 15.9%, with rates of 3.4% for seroma, 4.0% for SSI, 6.1% for dehiscence, 3.7% for explantation, 7.0% for flap loss, and 6.4% for reoperation. Individualized risk models were developed with acceptable goodness of fit, accuracy, and internal validity. Distribution of overall complication risk was broad and asymmetric, meaning that the average risk was often a poor estimate of the risk for any given patient. These models were added to the previously developed open-access version of the risk calculator, available at http://www.BRAscore.org. CONCLUSIONS: Population-based measures of risk may not accurately reflect risk for many individual patients. In this era of increasing emphasis on evidence-based medicine, we have developed a breast reconstruction risk assessment calculator from the robust TOPS database. The BRA Score tool can aid in individualizing-and quantifying-risk to better inform surgical decision making and better manage patient expectations.

RESUMO

SUMMARY: Clinical data registries are commonly used worldwide and are implemented for a variety of purposes ranging from physician or facility clinic logs for tracking patients, to collecting outcomes data, to measuring quality improvement or safety of medical devices. In the United States, the U.S. Food and Drug Administration has used data collected through registries to facilitate the drug and device regulatory process, for ongoing surveillance during the product life cycle, and for disease appraisals. Furthermore, the Centers for Medicare and Medicaid Services, in certain instances, bases registry participation and submitting data to registries as factors for reimbursement decisions. The purpose of this article is to discuss the use of clinical data registries; the role that medical specialty societies, in particular, the American Society of Plastic Surgeons and The Plastic Surgery Foundation, can have in the development and management of registries; and the opportunities for registry use in plastic surgery. As outcomes data are becoming essential measures of quality health care delivery, participation in registry development and centralized data collection has become a critical task for plastic surgery to engage in to proactively participate in the national quality and performance measurement agenda.
