RESUMO
BACKGROUND: This study explored physician anesthesiologists' knowledge, exposure, and perceptions of artificial intelligence (AI) and their associations with attitudes and expectations regarding its use in clinical practice. The findings highlight the importance of understanding anesthesiologists' perspectives for the successful integration of AI into anesthesiology, as AI has the potential to revolutionize the field. METHODS: A cross-sectional survey of 27,056 US physician anesthesiologists was conducted to assess their knowledge, perceptions, and expectations regarding the use of AI in clinical practice. The primary outcome measured was attitude toward the use of AI in clinical practice, with scores of 4 or 5 on a 5-point Likert scale indicating positive attitudes. The anticipated impact of AI on various aspects of professional work was measured using a 3-point Likert scale. Logistic regression was used to explore the relationship between participant responses and attitudes toward the use of AI in clinical practice. RESULTS: A 2021 survey of 27,056 US physician anesthesiologists received 1086 responses (4% response rate). Most respondents were male (71%), active clinicians (93%) under 45 (34%). A majority of anesthesiologists (61%) had some knowledge of AI and 48% had a positive attitude toward using AI in clinical practice. While most respondents believed that AI can improve health care efficiency (79%), timeliness (75%), and effectiveness (69%), they are concerned that its integration in anesthesiology could lead to a decreased demand for anesthesiologists (45%) and decreased earnings (45%). Within a decade, respondents expected AI would outperform them in predicting adverse perioperative events (83%), formulating pain management plans (67%), and conducting airway exams (45%). The absence of algorithmic transparency (60%), an ambiguous environment regarding malpractice (47%), and the possibility of medical errors (47%) were cited as significant barriers to the use of AI in clinical practice. Respondents indicated that their motivation to use AI in clinical practice stemmed from its potential to enhance patient outcomes (81%), lower health care expenditures (54%), reduce bias (55%), and boost productivity (53%). Variables associated with positive attitudes toward AI use in clinical practice included male gender (odds ratio [OR], 1.7; P < .001), 20+ years of experience (OR, 1.8; P < .01), higher AI knowledge (OR, 2.3; P = .01), and greater AI openness (OR, 10.6; P < .01). Anxiety about future earnings was associated with negative attitudes toward AI use in clinical practice (OR, 0.54; P < .01). CONCLUSIONS: Understanding anesthesiologists' perspectives on AI is essential for the effective integration of AI into anesthesiology, as AI has the potential to revolutionize the field.

BACKGROUND: Capsular contracture (CC) is a common complication following implant-based breast surgery, often requiring surgical intervention. Yet, little is known about risk factors and outcomes following CC surgery. METHODS: We reviewed the American College of Surgeons National Surgical Quality Improvement Program database (2008-2021) to identify female patients diagnosed with CC and treated surgically. Outcomes of interest included the incidence of surgical and medical complications at 30-days, reoperations, and readmissions. Confounder-adjusted multivariable analyses were performed to establish risk factors. RESULTS: 5,057 patients with CC were identified (mean age: 55 ± 12 years and mean body mass index [BMI]: 26 ± 6 kg/m2). While 2,841 (65%) women underwent capsulectomy, capsulotomy was performed in 742 patients (15%). Implant removal and replacement were recorded in 1,160 (23%) and 315 (6.2%) cases, respectively. 319 (6.3%) patients experienced postoperative complications, with 155 (3.1%) reoperations and 99 (2.0%) readmissions. While surgical adverse events were recorded in 139 (2.7%) cases, 86 (1.7%) medical complications occurred during the 30 day follow-up. In multivariate analyses, increased BMI (OR: 1.04; p = 0.009), preoperative diagnosis of hypertension (OR: 1.48; p = 0.004), and inpatient setting (OR: 4.15; p < 0.001) were identified as risk factors of complication occurrence. CONCLUSION: Based on 14 years of multi-institutional data, we calculated a net 30 day complication rate of 6.3% after the surgical treatment of CC. We identified higher BMI, hypertension, and inpatient setting as independent risk factors of postoperative complications. Plastic surgeons may wish to integrate these findings into their perioperative workflows, thus optimizing patient counseling and determining candidates' eligibility for CC surgery.

RESUMO
OBJECTIVE: Dedicated research time is a component of certain plastic surgery programs, and yet, there is limited research examining its impact on academic productivity and career outcomes. This study aimed to assess the effect of dedicated research time on the academic productivity of residents and the likelihood of pursuing an academic career. METHODS: We conducted a cross-sectional study that examined bibliometric indices of integrated plastic surgery residency graduates from 2010 to 2020. Academic productivity was determined by the number of peer-reviewed publications and h-index 1 year after residency graduation. Results were analyzed using descriptive statistics, χ2 test, t test, and logistic regression. RESULTS: Data on plastic surgery residency graduates were analyzed (N = 490 from 46 programs). The mean numbers of publications and h-index per research track graduate were 26.1 and 8.23, respectively. The mean numbers of publications and h-index per nonresearch track graduate were 15.9 and 5.97, respectively. After controlling for the University of Alabama research ranking through multilinear regression analysis, we found that pursuing dedicated research time was an independent predictor of increased h-index and publication output, although it did not predict an increased likelihood of pursuing an academic career. CONCLUSIONS: Participating in dedicated research during residency increases academic productivity, irrespective of the residency program's research rank. Given this finding, offering research years can help support the mission of fostering academic opportunities within plastic surgery.

ABSTRACT: An increasing number of plastic and reconstructive surgery (PRS) units have transitioned from divisions to departments in recent years. This study aimed to identify quantifiable differences that may reflect challenges and benefits associated with each type of unit. We conducted a cross-sectional analysis of publicly-available data on characteristics of academic medical institutions housing PRS units, faculty size of surgical units within these institutions, and academic environments of PRS units themselves. Univariate analysis compared PRS divisions versus departments. Matched-paired testing compared PRS units versus other intra-institutional surgical departments. Compared to PRS divisions (nâ=â64), departments (nâ=â22) are at institutions with more surgical departments overall (Pâ=â0.0071), particularly departments that are traditionally divisions within the department of surgery (ie urology). Compared to PRS divisions, PRS departments have faculty size that more closely resembles other intra-institutional surgical departments, especially for full-time surgical faculty and faculty in areas of clinical overlap with other departments like hand surgery. Plastic and reconstructive surgery departments differ from PRS divisions by certain academic measures, including offering more clinical fellowships (Pâ=â0.005), running more basic science laboratories (Pâ=â0.033), supporting more nonclinical research faculty (Pâ=â0.0417), and training residents who produce more publications during residency (Pâ=â0.002). Institutions with PRS divisions may be less favorable environments for surgical divisions to become departments, but other recently-transitioned divisions could provide blueprints for PRS to follow suit. Bolstering full-time surgical faculty numbers and faculty in areas of clinical overlap could be useful for PRS divisions seeking departmental status. Transitioning to department may yield objective academic benefits for PRS units.

BACKGROUND: We evaluated metrics between academic plastic surgeons that were and were not presidents of national organizations to determine predictors of becoming a president. METHODS: A cross-sectional retrospective review was performed. Websites were queried of 99 Accreditation Council for Graduate Medical Education accredited plastic surgery residency programs and 17 national organizations. Demographic, academic and scholarly variables we collected from 951 full-time plastic surgery faculty affiliated with the US residency training programs during the 2020-2021 academic year. Of these full-time plastic surgery faculty, 879 were non-presidents and 72 were presidents of national organizations (2016-2021 = 42, < 2016 = 30). RESULTS: Plastic surgeons were more likely to become president if they were an officer/director of the American Board of Plastic Surgeons (ABPS) (OR: 16.67, 95%CI: 5.83, 47.66; p < 0.001), chief/chair of a division/department (OR: 3.10, 95%CI: 1.09, 8.79; p = 0.033), endowed (OR: 5.45, 95%CI:1.65, 18.04; p = 0.006), National Institutes of Health (NIH) funded (OR: 4.57, 95%CI: 1.24, 16.88; p = 0.023), affiliated with an integrated plastic surgery residency program (OR: 3.96, 95%CI: 1.27, 12.33; p = 0.018), and with a greater number of years in practice (OR: 1.09, 95%CI: 1.04, 1.14; p < 0.001). Additionally, plastic surgeons were more likely to become president between 2016 and 2021 with a research fellowship (OR: 7.41, 95%CI: 1.02, 52.63; p = 0.047), first author publications (OR: 1.72, 95%CI: 1.63, 1.83; p < 0.001), and last author publications (OR: 1.60, 95%CI: 1.56, 1.65; p < 0.001). CONCLUSIONS: Plastic surgeons were more likely to become president of a national organization if they were an officer/director of the ABPS, chief/chair of a division/department, endowed, NIH funded, affiliated with an integrated plastic surgery residency program, greater number of years in practice, research fellowship, and first and last author publications. Predictors may guide those interested in becoming president of a national organization. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

ABSTRACT: Chairs/chiefs of plastic surgery departments/divisions are responsible for directing activities at academic institutions and thus help determine the direction of academic plastic surgery. Other studies have characterized this group but have not shown which characteristics separate them from other surgeons in the field. To study this relationship, a cross-sectional analysis of plastic surgery faculty affiliated with United States residency training programs (nâ=â99) was initiated. Data were collected from public online websites. Univariate and multivariate logistic regression were used to identify factors independently associated with chairs/chief status. Sub-analyses were performed within Tiers stratified by residency program rank of chair/chief's current institution. Among 943 plastic surgeons, 98âchairs/chiefs were identified. In accordance with prior literature, most are male (89%) and fellowship-trained (62%), and they have a median H-index of 17. Compared to other surgeons, chair/chiefs have more years in practice (odds ratio [OR]: 1.026, confidence interval [CI]: 0.002-0.049, Pâ=â0.034), higher H-index (OR: 1.103, CI: 0.048-0.147, Pâ<â0.001), and more citations (OR: 1.000, CI: -0.000 to -0.001, Pâ=â0.006). Chair/chiefs were also more likely to be journal editorial board members (OR: 1.728, CI: -0.033 to 1.127, Pâ=â0.046) and national society/organization presidents (OR: 1.024, CI: 0.008-0.039, Pâ=â0.003). No notable differences were found between department chairs versus division chiefs or across Tiers. Overall, scholarly achievement and significant years of experience distinguish chairs/chiefs in American academic plastic surgery. Criteria for achieving this leadership role may not differ between departments and divisions. Further research is needed to evaluate whether these characteristics translate into more effective leadership.

BACKGROUNDS: Academic plastic surgery has utilized different methods to promote early involvement of trainees in research. Further analysis is needed to characterize the effects of this early emphasis and their impact on long-term academic contributions to the field. METHODS: In October 2020, a cross-sectional study of 949 faculty from US academic plastic surgery programs was conducted using publicly available websites. Training research output for each surgeon was compared to post-training research output and other metrics measuring sustained career scholarship. RESULTS: Increased training publications (P< 0.0001) and citations (P< 0.0001) were associated with fewer years in practice. 727 surgeons (80.0%) had ≥ 1 research article, and this group proceeded to attain significantly higher mean post-training publications per year (3.04 ± 0.14 vs. 1.45 ± 0.13, P< 0.0001) and citations per year (72.12 ± 5.04 vs. 28.39 ± 3.49, P< 0.0001) compared to the 182 (20.0%) surgeons with no training publications. For individuals, total training publications were positively correlated with post-training publications per year (P< 0.0001), a relationship also observed for citations (P< 0.0001). When controlling for years in practice, increased training publications and/or citations were significantly associated with attaining academic professor track (versus clinical professor track) position, endowed professor status, journal board position, and NIH funding (P< 0.05 for all). CONCLUSIONS: There is a trend of increasing research productivity during plastic surgery training, and increased training output is predictive of attaining multiple measures of career academic achievement. Academic plastic surgery should continue to underscore research participation as a valuable part of the training process.

OBJECTIVE: Plastic surgery is one of the most competitive and innovative fields in medicine. The role of the academic plastic surgeon continues to grow beyond clinical care, and many surgeons have pursued advanced degrees (AD) to expand their professional skillset. We present an analysis of ADs of academic plastic surgery faculty in the USA, with consideration of timing of AD attainment. METHODS: All academic plastic surgery faculty members were identified from plastic surgery program websites, as recognized by the American Council of Academic Plastic Surgeons. ADs were defined as additional degrees beyond the primary medical degree. Outcomes included timing of AD attainment, residency rankings, institutional standings, and research productivity. RESULTS: 949 faculty members were identified, and 167 had ADs. The most common ADs were PhD (30%), MS/MSc (18%), and MBA/EMBA (17%). Timing of AD attainment was available for 146 faculty members (84.7%). Having an AD before residency was associated with matching into higher-tiered and integrated residency programs (both p < 0.05). For attending physicians, having an AD was associated with more journal editorial board positions, more publications, higher H-index, receiving NIH funding, and median number of NIH grants (adjusted for years in practice, all p<0.05). Institutional analysis revealed that employing more faculty with an AD was associated with having an integrated residency program, higher residency research ranking, and higher tier integrated residency (all p < 0.05). CONCLUSION: ADs are growing in popularity in academic plastic surgery and are temporally associated with specific advantages in terms of residency placement, research productivity, and institutional standing. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable. This excludes Review Articles, Book Reviews, and manuscripts that concern Basic Science, Animal Studies, Cadaver Studies, and Experimental Studies.

Adeno-associated virus-mediated gene replacement is emerging as a safe and effective means of correcting single-gene mutations affecting the CNS. AAV-mediated progranulin gene (GRN) delivery has been proposed as a treatment for GRN-deficient frontotemporal dementia and neuronal ceroid lipofuscinosis, and recent studies using intraparenchymal AAV-Grn delivery to brain have shown moderate success in histopathologic and behavioral rescue in mouse models. Here, we used AAV9 to deliver GRN to the lateral ventricle to achieve widespread expression in the Grn null mouse brain. We found that, despite a global increase in progranulin, overexpression resulted in dramatic and selective hippocampal toxicity and degeneration affecting neurons and glia. Hippocampal degeneration was preceded by T cell infiltration and perivascular cuffing. GRN delivery with an ependymal-targeting AAV for selective secretion of progranulin into the cerebrospinal fluid similarly resulted in T cell infiltration, as well as ependymal hypertrophy. Interestingly, overexpression of GRN in wild-type animals also provoked T cell infiltration. These results call into question the safety of GRN overexpression in the CNS, with evidence for both a region-selective immune response and cellular proliferative response. Our results highlight the importance of careful consideration of target gene biology and cellular response to overexpression prior to progressing to the clinic.

We examined the origins and functional evolution of the Shaker and KCNQ families of voltage-gated K(+) channels to better understand how neuronal excitability evolved. In bilaterians, the Shaker family consists of four functionally distinct gene families (Shaker, Shab, Shal, and Shaw) that share a subunit structure consisting of a voltage-gated K(+) channel motif coupled to a cytoplasmic domain that mediates subfamily-exclusive assembly (T1). We traced the origin of this unique Shaker subunit structure to a common ancestor of ctenophores and parahoxozoans (cnidarians, bilaterians, and placozoans). Thus, the Shaker family is metazoan specific but is likely to have evolved in a basal metazoan. Phylogenetic analysis suggested that the Shaker subfamily could predate the divergence of ctenophores and parahoxozoans, but that the Shab, Shal, and Shaw subfamilies are parahoxozoan specific. In support of this, putative ctenophore Shaker subfamily channel subunits coassembled with cnidarian and mouse Shaker subunits, but not with cnidarian Shab, Shal, or Shaw subunits. The KCNQ family, which has a distinct subunit structure, also appears solely within the parahoxozoan lineage. Functional analysis indicated that the characteristic properties of Shaker, Shab, Shal, Shaw, and KCNQ currents evolved before the divergence of cnidarians and bilaterians. These results show that a major diversification of voltage-gated K(+) channels occurred in ancestral parahoxozoans and imply that many fundamental mechanisms for the regulation of action potential propagation evolved at this time. Our results further suggest that there are likely to be substantial differences in the regulation of neuronal excitability between ctenophores and parahoxozoans.

Mammalian Ether-a-go-go related gene (Erg) family voltage-gated K(+) channels possess an unusual gating phenotype that specializes them for a role in delayed repolarization. Mammalian Erg currents rectify during depolarization due to rapid, voltage-dependent inactivation, but rebound during repolarization due to a combination of rapid recovery from inactivation and slow deactivation. This is exemplified by the mammalian Erg1 channel, which is responsible for IKr, a current that repolarizes cardiac action potential plateaus. The Drosophila Erg channel does not inactivate and closes rapidly upon repolarization. The dramatically different properties observed in mammalian and Drosophila Erg homologs bring into question the evolutionary origins of distinct Erg K(+) channel functions. Erg channels are highly conserved in eumetazoans and first evolved in a common ancestor of the placozoans, cnidarians, and bilaterians. To address the ancestral function of Erg channels, we identified and characterized Erg channel paralogs in the sea anemone Nematostella vectensis. N. vectensis Erg1 (NvErg1) is highly conserved with respect to bilaterian homologs and shares the IKr-like gating phenotype with mammalian Erg channels. Thus, the IKr phenotype predates the divergence of cnidarians and bilaterians. NvErg4 and Caenorhabditis elegans Erg (unc-103) share the divergent Drosophila Erg gating phenotype. Phylogenetic and sequence analysis surprisingly indicates that this alternate gating phenotype arose independently in protosomes and cnidarians. Conversion from an ancestral IKr-like gating phenotype to a Drosophila Erg-like phenotype correlates with loss of the cytoplasmic Ether-a-go-go domain. This domain is required for slow deactivation in mammalian Erg1 channels, and thus its loss may partially explain the change in gating phenotype.

We examined the evolutionary origins of the ether-à-go-go (EAG) family of voltage-gated K(+) channels, which have a strong influence on the excitability of neurons. The bilaterian EAG family comprises three gene subfamilies (Eag, Erg and Elk) distinguished by sequence conservation and functional properties. Searches of genome sequence indicate that EAG channels are metazoan specific, appearing first in ctenophores. However, phylogenetic analysis including two EAG family channels from the ctenophore Mnemiopsis leidyi indicates that the diversification of the Eag, Erg and Elk gene subfamilies occurred in a cnidarian/bilaterian ancestor after divergence from ctenophores. Erg channel function is highly conserved between cnidarians and mammals. Here we show that Eag and Elk channels from the sea anemone Nematostella vectensis (NvEag and NvElk) also share high functional conservation with mammalian channels. NvEag, like bilaterian Eag channels, has rapid kinetics, whereas NvElk activates at extremely hyperpolarized voltages, which is characteristic of Elk channels. Potent inhibition of voltage activation by extracellular protons is conserved between mammalian and Nematostella EAG channels. However, characteristic inhibition of voltage activation by Mg(2+) in Eag channels and Ca(2+) in Erg channels is reduced in Nematostella because of mutation of a highly conserved aspartate residue in the voltage sensor. This mutation may preserve sub-threshold activation of Nematostella Eag and Erg channels in a high divalent cation environment. mRNA in situ hybridization of EAG channels in Nematostella suggests that they are differentially expressed in distinct cell types. Most notable is the expression of NvEag in cnidocytes, a cnidarian-specific stinging cell thought to be a neuronal subtype.

INTRODUCTION: Anatomic and reverse total shoulder arthroplasties (TSAs) are effective treatment options for end-stage glenohumeral osteoarthritis. Those undergoing TSA may also have fibromyalgia, a musculoskeletal condition. However, the association of fibromyalgia with shorter and longer term outcomes after TSA has not been well characterized. METHODS: Patients undergoing TSA for osteoarthritis indications were identified in the PearlDiver M165 database from January 2016 to October 2022. Exclusion criteria included age younger than 18 years, shoulder infection, neoplasm, or trauma within 90 days before surgery, and inactivity in the database within 90 days of surgery. Patients with fibromyalgia were matched in a 1:4 ratio to patients without based on age, sex, and Elixhauser Comorbidity Index. Ninety-day adverse events were compared using univariable and multivariable analyses. Five-year revision-free survival was compared using the log-rank test. RESULTS: Of 163,565 TSA patients, fibromyalgia was identified for 9,035 (5.52%). After matching, cohorts of 30,770 non-fibromyalgia patients and 7,738 patients with fibromyalgia were identified. Multivariable analyses demonstrated patients with fibromyalgia were at independently increased odds ratios (ORs) for the following 90-day complications (decreasing OR order): urinary tract infection (OR = 4.49), wound dehiscence (OR = 3.63), pneumonia (OR = 3.46), emergency department visit (OR = 3.45), sepsis (OR = 3.15), surgical site infection (OR = 2.82), cardiac events (OR = 2.72), acute kidney injury (OR = 2.65), deep vein thrombosis (OR = 2.48), hematoma (OR = 2.03), and pulmonary embolism (OR = 2.01) (P < 0.05 for each). These individual complications contributed to the increased odds of aggregated minor adverse events (OR = 3.68), all adverse events (OR = 3.48), and severe adverse events (OR = 2.68) (P < 0.05 for each). No statistically significant difference was observed in 5-year revision-free survival between groups. DISCUSSION: This study found TSA patients with fibromyalgia to be at increased risk of adverse events within 90 days of surgery. Proper surgical planning and patient counseling are crucial to this population. Nonetheless, it was reassuring that those with fibromyalgia had similar 5-year revision-free survival compared with those without.

BACKGROUND: Breast fat necrosis (BFN) is a non-cancerous condition affecting the adipose tissue. Despite incidence rates of up to 25% after breast surgery, little is known about risk factors and postoperative outcomes following the surgical treatment of BFN. METHODS: The National Surgical Quality Improvement Program of the American College of Surgeons (2008-2021) was queried to identify female patients diagnosed with and surgically treated for BFN. Outcomes of interest included 30-day surgical and medical complications, reoperation, and readmission. We performed confounder-adjusted multivariable analyses to determine risk factors. RESULTS: The study population included 1179 female patients (mean age: 55.8 ± 13.8 years), of whom 96% (n = 1130) underwent direct excision and 4.2% (n = 49) received debridement of necrotic tissue. The majority of cases were operated on by general surgeons (n = 867; 74%) in the outpatient setting (n = 1107; 94%). Overall, 74 patients (6.3%) experienced postoperative adverse events, most of which were surgical complications (n = 43; 3.7%). Twenty-one (1.8%) women had to return to operating room, while readmission was reported in 18 (1.5%) cases. Adverse events were significantly more likely to occur in patients with chronic heart failure (p = 0.002) and higher wound classes (p = 0.033). CONCLUSION: Complication rates following the surgical management of BFN were found to be relatively high and seen to correlate with the setting. We identified chronic heart failure and wound contamination as risk factors for complication occurrence. These evidence-based insights may sensitize surgeons to critically balance patients' eligibility for BFN surgery and refine perioperative algorithms.

BACKGROUND: Breast cancer mortality and treatment differ across racial groups. It remains unclear whether such disparities are also reflected in perioperative outcomes of breast cancer patients undergoing mastectomy. STUDY DESIGN: The authors reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2008-2021) to identify female patients who underwent mastectomy for oncological purposes. The outcomes were stratified by five racial groups (white, Black/African American, Asian, American Indian/Alaska Native, and Native Hawaiian/Pacific Islander) and included 30-day mortality, reoperation, readmission, surgical and medical complications, and non-home discharge. RESULTS: The study population included 222 947 patients, 68% ( n =151 522) of whom were white, 11% ( n =23 987) Black/African American, 5% ( n =11 217) Asian, 0.5% ( n =1198) American Indian/Alaska Native, and 0.5% ( n =1018) Native Hawaiian/Pacific Islander. While 136 690 (61%) patients underwent partial mastectomy, 54 490 (24%) and 31 767 (14%) women received simple and radical mastectomy, respectively. Overall, adverse events occurred in 17 222 (7.7%) patients, the largest portion of which were surgical complications ( n =7246; 3.3%). Multivariable analysis revealed that being of Asian race was protective against perioperative complications [odds ratio (OR)=0.71; P <0.001], whereas American Indian/Alaska Native women were most vulnerable to the complication occurrence (OR=1.41; P <0.001). Black/African American patients had a significantly lower risk of medical (OR=0.59; P <0.001) and surgical complications (OR=0.60; P <0.001) after partial and radical mastectomy, respectively, their likelihood of readmission (OR=1.14; P =0.045) following partial mastectomy was significantly increased. CONCLUSION: The authors identified American Indian/Alaska Native women as particularly vulnerable to complications following mastectomy. Asian patients experienced the lowest rate of complications in the perioperative period. The authors' analyses revealed comparable confounder-adjusted outcomes following partial and complete mastectomy between Black and white races. Their findings call for care equalization in the field of breast cancer surgery.

Balancing the immune response after solid organ transplantation (SOT) and vascularized composite allotransplantation (VCA) remains an ongoing clinical challenge. While immunosuppressants can effectively reduce acute rejection rates following transplant surgery, some patients still experience recurrent acute rejection episodes, which in turn may progress to chronic rejection. Furthermore, these immunosuppressive regimens are associated with an increased risk of malignancies and metabolic disorders. Despite significant advancements in the field, these IS related side effects persist as clinical hurdles, emphasizing the need for innovative therapeutic strategies to improve transplant survival and longevity. Cellular therapy, a novel therapeutic approach, has emerged as a potential pathway to promote immune tolerance while minimizing systemic side-effects of standard IS regiments. Various cell types, including chimeric antigen receptor T cells (CAR-T), mesenchymal stromal cells (MSCs), regulatory myeloid cells (RMCs) and regulatory T cells (Tregs), offer unique immunomodulatory properties that may help achieve improved outcomes in transplant patients. This review aims to elucidate the role of cellular therapies, particularly MSCs, T cells, Tregs, RMCs, macrophages, and dendritic cells in SOT and VCA. We explore the immunological features of each cell type, their capacity for immune regulation, and the prospective advantages and obstacles linked to their application in transplant patients. An in-depth outline of the current state of the technology may help SOT and VCA providers refine their perioperative treatment strategies while laying the foundation for further trials that investigate cellular therapeutics in transplantation surgery.

Injuries to our skin trigger a cascade of spatially- and temporally-synchronized healing processes. During such endogenous wound repair, the role of fibroblasts is multifaceted, ranging from the activation and recruitment of innate immune cells through the synthesis and deposition of scar tissue to the conveyor belt-like transport of fascial connective tissue into wounds. A comprehensive understanding of fibroblast diversity and versatility in the healing machinery may help to decipher wound pathologies whilst laying the foundation for novel treatment modalities. In this review, we portray the diversity of fibroblasts and delineate their unique wound healing functions. In addition, we discuss future directions through a clinical-translational lens.

Facial vascularized composite allotransplantation (fVCA) represents a valuable surgical option for reconstruction of the most devastating facial defects. There is a mounting body of evidence suggesting that healthcare disparities exist for a variety of other surgical and nonsurgical procedures. We aimed to investigate the potential existence of racial and ethnic disparities in the field of fVCA. Methods: A comprehensive literature review was conducted by the authors of this review on PubMed/MEDLINE, and Embase databases from database inception to December 1, 2022 for studies published in the English and French languages. The search terms were (1) "face" OR "facial" AND (2) "transplant" OR "VCA" OR "vascularized composite allotransplantation" OR "vascularized composite allograft" OR "graft." Results: Upon assessment of the racial and ethnic demographics of the 47 global cases of fVCA between 2005 and 2020, 36 were White, 10 were Asian, and one was Black. Sixteen of the 17 fVCA procedures performed in the United States involved White patients. The other patient self-identified as Black, equaling 6% of all US fVCA recipients. Conclusion: Our analysis showed that the ethnic and racial distribution of fVCA has not proportionally reflected the racial and ethnic demographics of the general US population, underscoring the risk of such healthcare imbalances. Although large-scale studies are needed before drawing definitive conclusions, leaders in the field should take preventive steps to avoid potential disparities. Further investigations into the factors that facilitate or prohibit access to fVCA referral and surgery will be necessary moving forward.
RESUMO
Background Fellowship training is becoming more popular in plastic surgery, with over half of residents pursuing advanced training. Here, we investigate how clinical and research fellowship training impacts career trajectory and scholastic achievement in academic plastic surgery. Methods Plastic surgery faculty members, from programs recognized by the American Council of Academic Plastic Surgeons, were identified using institutional Web sites. Data extracted included faculty demographics, training history, academic positions, and research productivity. Continuous and categorical variables were compared using t -tests and chi-square, respectively. Results In total, 949 faculty members were included, with 657 (69%) having completed fellowship training. Integrated program residents were more likely to complete a fellowship when compared with independent residents ( p < 0.0001). Fellowship trained faculty were more likely to have graduated from a higher ranked residency program, in terms of both overall and research reputation ( p = 0.005 and p = 0.016, respectively). When controlling for years in practice, there was no difference found in number of publications, Hirsch index (h-index), or National Institutes of Health funding between faculty between the two cohorts ( p > 0.05). In a subanalysis comparing hand, craniofacial, microsurgery, and research fellowships, those who completed a research fellowship had higher h-indices and were more likely to reach full professor status ( p < 0.001 and p = 0.001, respectively). Fellowship training had no effect on being promoted to Chief/Chair of departments ( p = 0.16). Conclusion Fellowship training is common among academic plastic surgeons. In this study, both clinical and research fellowships were associated with various aspects of academic success. However, fellowship training alone did not affect attainment of leadership positions.
RESUMO
Background: Lack of female and ethnically underrepresented in medicine (UIM) surgeons remains concerning in academic plastic surgery. One barrier to inclusion may be unequal opportunity to publish research. This study evaluates the extent of this challenge for plastic surgery trainees and identifies potential solutions. Methods: Data were collected on academic plastic surgeons' research productivity during training. Bivariate analysis compared publication measures between genders and race/ethnicities at different training stages (pre-residency/residency/clinical fellowship). Multivariate analysis determined training experiences independently associated with increased research productivity. Results: Overall, women had fewer total publications than men during training (8.89 versus 12.46, P = 0.0394). Total publications were similar between genders before and during residency (P > 0.05 for both) but lower for women during fellowship (1.32 versus 2.48, P = 0.0042). Women had a similar number of first-author publications during training (3.97 versus 5.24, P = 0.1030) but fewer middle-author publications (4.70 versus 6.81, P = 0.0405). UIM and non-UIM individuals had similar productivity at all training stages and authorship positions (P > 0.05 for all). Research fellowship completion was associated with increased total, first-, and middle-author training publications (P < 0.001 for all). Conclusions: Less research productivity for female plastic surgery trainees may reflect a disparity in opportunity to publish. Fewer middle-author publications could indicate challenges with network-building in a predominately male field. Despite comparable research productivity during training relative to non- UIM individuals, UIM individuals remain underrepresented in academic plastic surgery. Creating research fellowships for targeting underrepresented groups could help overcome these challenges.
