Breast cancer-related lymphedema: A comprehensive analysis of risk factors.

BACKGROUND: Breast cancer-related lymphedema is a devastating condition that negatively affects the quality of life of breast cancer survivors. We sought to identify risk factors that predicted the timing and development of lymphedema. METHODS: Women with breast cancer that underwent sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) at our institution between 2007 and 2022 were identified and sociodemographic and clinical information was extracted. We used logistic regression analysis to identify risk factors for lymphedema and performed cox-regression analysis to predict the timing of lymphedema presentation after surgery. RESULTS: We identified 1,223 patients, of which 161 (13.2%) developed lymphedema within 1.8 (mean, SD = 2.5) years postoperatively. Patients with SLNB had significantly lower odds for lymphedema development (vs. ALND, OR = 0.29 [0.14-0.57]). Patients between 40 and 49 years of age, and 50-59 (vs. <40 years, OR = 2.14 [1.00-4.60]; OR = 2.42, [1.13-5.16] respectively), African American patients (vs. Caucasian, OR = 1.86 [1.12-3.09]), patients with stage II, III, and IV disease (vs. stage 0, OR = 3.75 [1.36-10.33]; OR = 6.62 [2.14-20.51]; OR = 9.36 [2.94-29.81]), and patients with Medicaid (vs. private insurance, OR = 3.56 [1.73-7.28]) had higher rates of lymphedema. Cox-regression analysis showed that African American (HR = 1.71 [1.08-2.70]), higher BMI (HR = 1.03 [1.00-1.06]), higher stage (stage II, HR = 2.22 [1.05-7.09]; stage III, HR = 5.26 [1.86-14.88]; stage IV, HR = 6.13 [2.12-17.75]), and Medicaid patients (HR = 2.15 [1.12-3.80]) had higher hazards for lymphedema. Patients with SLNB had lower hazards for lymphedema (HR = 0.43 [0.87-2.11]). CONCLUSION: Lymphedema has identifiable risk factors that can reliably be used to predict the chances of lymphedema development and enable clinicians to educate patients better and formulate treatment plans accordingly. LEVEL OF EVIDENCE: III (Retrospective study).

Predicting Reduction Mammaplasty Total Resection Weight With Machine Learning.

BACKGROUND: Machine learning (ML) is a form of artificial intelligence that has been used to create better predictive models in medicine. Using ML algorithms, we sought to create a predictive model for breast resection weight based on anthropometric measurements. METHODS: We analyzed 237 patients (474 individual breasts) who underwent reduction mammoplasty at our institution. Anthropometric variables included body surface area (BSA), body mass index, sternal notch-to-nipple (SN-N), and nipple-to-inframammary fold values. Four different ML algorithms (linear regression, ridge regression, support vector regression, and random forest regression) either including or excluding the Schnur Scale prediction for the same data were trained and tested on their ability to recognize the relationship between the anthropometric variables and total resection weights. Resection weight prediction accuracy for each model and the Schnur scale alone were evaluated based on using mean absolute error (MAE). RESULTS: In our cohort, mean age was 40.36 years. Most patients (71.61%) were African American. Mean BSA was 2.0 m 2 , mean body mass index was 33.045 kg/m 2 , mean SN-N was 35.0 cm, and mean nipple-to-inframammary fold was 16.0 cm. Mean SN-N was found to have the greatest variable importance. All 4 models made resection weight predictions with MAE lower than that of the Schnur Scale alone in both the training and testing datasets. Overall, the random forest regression model without Schnur scale weight had the lowest MAE at 186.20. CONCLUSION: Our ML resection weight prediction model represents an accurate and promising alternative to the Schnur Scale in the setting of reduction mammaplasty consultations.

Crouzon Syndrome Spanning Three Generations: Advances in the Treatment of Syndromic Midface Deficiency.

Background: Crouzon syndrome is an autosomal dominant genetic disorder characterized by craniosynostosis, midface retrusion, and exophthalmos. Over the past century, the treatment of craniofacial disorders like Crouzon syndrome has evolved significantly. Methods: An institutional review board-approved retrospective study was conducted to ascertain the treatment of three individuals with Crouzon syndrome from one family, complemented with a series of literature searches to examine the evolution of craniofacial surgical history. Results: Dr. David Williams Cheever developed the Le Fort I level to correct malocclusion, maxillomandibular malformations, and midface hypoplasia. Later, Dr. Paul Tessier introduced the Le Fort II and III osteotomies to treat syndromic midface hypoplasia. In 1978, Dr. Fernando Ortiz-Monasterio and Dr. Antonio Fuente del Campo published the first series of monobloc osteotomies, allowing for simultaneous correction of supraorbital and midface malformations, although complicated by blood loss and high infection rates. In 1992, McCarthy et al introduced the concept of gradual distraction to the craniofacial skeleton. In 1995, Polley et al performed the first monobloc advancement using external distraction. Subsequently, in 1997, Polley and Figueroa introduced a rigid external distraction device with multiple vector control to manage severe cleft maxillary hypoplasia. The technique was further refined and applied to treat syndromic midface hypoplasia, reducing complication rates. Currently, either external or internal distraction approaches are used to safely treat this challenging group of patients. Conclusion: The treatment of syndromic midface deficiency has significantly evolved over the past 50 years, as evidenced by this report of three generations of Crouzon syndrome.

Chondrolaryngoplasty with Endoscopic Direct Visualization of the Vocal Cords: Demonstration of Technique.

SUMMARY: Chondrolaryngoplasty is a surgical procedure that reduces a prominent thyroid cartilage. Demand for chondrolaryngoplasty has significantly increased over recent years in transgender women and nonbinary individuals and has been shown to alleviate gender dysphoria and improve quality of life. When performing chondrolaryngoplasty, surgeons must carefully balance the desire for maximal cartilage reduction with the potential for damage to surrounding structures (ie, the vocal cords) that may result because of overaggressive or imprecise resection. Our institution has adopted the technique of direct vocal cord endoscopic visualization using a flexible laryngoscope for increased safety. Briefly, surgical steps include dissection and preparation for translaryngeal needle placement, endoscopic visualization of the needle placed above the level of the vocal cords, marking of the corresponding level, and resection of the thyroid cartilage. The following article and supplemental video provide further detailed descriptions of these surgical steps as a resource for training and technique refinement.

The Burden of COVID-19 on Surgeons' Financial Relationship with the Industry.

The healthcare system has been greatly affected by the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to compare pre-COVID-19 and post-COVID-19 payments between industry and medical providers for all surgeons and subspecialized surgeons. Payment information was obtained from the Open Payments Program database for the 2019 and 2020 reported periods for three physician groups: all physicians, all surgeons, and each surgical subspecialty. Comparison and analysis of payment amount and type between these years was performed for each cohort. Physicians experienced a 36% decrease in industry payments with surgeons experiencing a 30.4% decrease. All surgical subspecialties, including plastic surgery (-30.5%; P < 0.01), experienced a significant decrease in industry payments except for transplant surgery, trauma surgery, and neurological surgery. Charitable contributions and compensation for services other than consulting were the only payment types that increased from 2019 to 2020. The COVID-19 pandemic has significantly impacted industry physician payments across all medical and surgical fields with payment decreases across almost all surgical subspecialties.

Associations between SARS-CoV-2 infections and thrombotic complications necessitating surgical intervention: A systematic review.

BACKGROUND: Several unique clinical features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease 2019 (COVID-19) infection, have been identified and characterized. One such feature, mostly among patients with severe COVID-19 infection, has become known as COVID-19-induced coagulopathy. Surgical patients with a history of or active COVID-19 infection bear a significantly higher risk for postoperative thrombotic complications. These patients may require surgical intervention to treat severe thrombotic complications. Few studies have been carried out to better characterize this association. The purpose of this study was to perform a systematic review and meta-analysis of the literature on COVID-19 infections that led to thrombotic complications necessitating surgical intervention. We hypothesized that patients with recent or active COVID-19 infection would have high rates of thromboembolic complications both arterial and venous in origin. AIM: To perform a systematic review and meta-analysis of the literature on COVID-19 infections that led to thrombotic complications necessitating surgical intervention. METHODS: The current systematic review implemented an algorithmic approach to review all the currently available English medical literature on surgical interventions necessitated by COVID-19 thrombotic complications using the preferred reporting items for systematic reviews and meta-analysis principles. A comprehensive search of the medical literature in the "PubMed", "Scopus", "Google Scholar" top 100 results, and archives of Plastic and Reconstructive Surgery was performed using the key words "COVID-19" AND "surgery" AND "thromboembolism" AND "complication". The search string was generated and the records which were not specific about surgical interventions or thrombotic complications due to COVID-19 infection were excluded. Titles and abstracts were screened by two authors and full-text articles were assessed for eligibility and inclusion. Finally, results were further refined to focus on articles that focused on surgical interventions that were necessitated by COVID-19 thrombotic complications. RESULTS: The database search resulted in the final inclusion of 22 retrospective studies, after application of the inclusion/exclusion criteria. Of the included studies, 17 were single case reports, 3 were case series and 2 were cross sectional cohort studies. All studies were retrospective in nature. Twelve of the reported studies were conducted in the United States of America, with the remaining studies originating from Italy, Turkey, Pakistan, France, Serbia, and Germany. All cases reported in our study were laboratory confirmed SARS-CoV-2 positive. A total of 70 cases involving surgical intervention were isolated from the 22 studies included in this review. CONCLUSION: There is paucity of data describing the relationship between COVID-19 infection and thrombotic complications necessitating the need for surgical intervention. Intestinal ischemia and acute limb ischemia are amongst the most common thrombotic events due to COVID-19 that required operative management. An overall postoperative mortality of 30% was found in those who underwent operative procedures for thrombotic complications, with most deaths occurring in those with bowel ischemia. Physicians should be aware that despite thromboprophylaxis, severe thrombotic complications can still occur in this patient population, however, surgical intervention results in relatively low mortality apart from cases of ischemic bowel resection.

Impact of gender-affirming hormone therapy on the development of COVID-19 infections and associated complications: A systematic review.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can produce a wide range of clinical manifestations from asymptomatic to life-threatening. Various researchers have worked to elucidate the pathogenic mechanisms underlying these variable presentations. Differences in individual responses to systemic inflammation and coagulopathy appear to be modulated by several factors, including sex steroid hormones. Transgender men or non-binary individuals who undergo gender-affirming hormone therapy (GAHT) are a unique population of interest for exploring the androgen-mediated coronavirus disease 2019 (COVID-19) hypothesis. As the search for reliable and effective COVID-19 treatments continues, understanding the risks and benefits of GAHT may mitigate COVID-19 related morbidity and mortality in this patient population. AIM: To investigate the potential role of GAHT in the development of COVID-19 infections and complications. METHODS: This systematic review implemented an algorithmic approach using PRISMA guidelines. PubMed, Scopus, Google Scholar top 100 results, and archives of Plastic and Reconstructive Surgery was on January 12, 2022 using the key words "gender" AND "hormone" AND "therapy" AND "COVID-19" as well as associated terms. Non-English articles, articles published prior to 2019 (prior to COVID-19), and manuscripts in the form of reviews, commentaries, or letters were excluded. References of the selected publications were screened as well. RESULTS: The database search resulted in the final inclusion of 14 studies related to GAHT COVID-19. Of the included studies, only two studies directly involved and reported on COVID-19 in transgender patients. Several clinical trials looked at the relationship between testosterone, estrogen, and progesterone in COVID-19 infected cis-gender men and women. It has been proposed that androgens may facilitate initial COVID-19 infection, however, once this occurs, testosterone may have a protective effect. Multiple clinical studies have shown that low baseline testosterone levels in men with COVID-19 are associated with worsening outcomes. The role of female sex hormones, including estrogen and progesterone have also been proposed as potential protective factors in COVID-19 infection. This was exemplified in multiple studies investigating different outcomes in pre- and post-menopausal women as well as those taking hormone replacement therapy. Two studies related specifically to transgender patients and GAHT found that estrogen and progesterone could help protect men against COVID-19, and that testosterone hormone therapy may increase the risk of contracting COVID-19. CONCLUSION: Few studies were found related to the role of GAHT in COVID-19 infections. Additional research is necessary to enhance our understanding of this relationship and provide better care for transgender patients.

Is There a Role for Comfort Care in Neonates With Severe Craniofacial Anomalies? Case Report and Review of Quality-of-Life Literature.

This article aims to determine how quality of life (QoL) is defined and assessed in cases of severe craniofacial anomalies, as well as the impact such considerations may have on the treatment of a neonate with these conditions with respect to palliative neonatal care. Our literature review found insufficient evidence to suggest that craniofacial anomalies result in consistently poor QoL. Based on these findings and in line with the current acceptable standards for the ethical care of neonates, with the exception of rare cases, resuscitative efforts should always be performed on patients with isolated craniofacial anomalies, as demonstrated in the management of this reported patient.

Plastic Surgeons and their Financial Relationships with the Industry in the era of COVID: Insights from the Physician Payments Sunshine Act.

BACKGROUND: The impact of the COVID-19 pandemic on physician relationships with industry and subsequent financial implications has not been previously assessed. The aim of this study is to compare pre- and post-COVID-19 payments between industry and medical providers for all plastic surgeons. METHODS: Payment information was collected for the 2019 and 2020 reporting periods from the Open Payments Program (OPP) database for plastic surgeons and plastic surgeon subspecialists. An analysis was performed of trends and comparison of payments for each year for all plastic surgeons and each subspecialty cohort. RESULTS: For all plastic surgeons, there was a decrease in industry payments between 2019 and 2020 (- 30.5%). All plastic surgery subspecialties had a decrease in payments with general plastic and reconstructive surgery affected the most (- 56%) and craniofacial surgery affected the least (- 9%). Payments for almost all categories for plastic surgeons decreased along with compensation as faculty or as speakers. Total charitable contributions and grant payments increased by 61 and 273%, respectively. CONCLUSION: Analysis of industry-physician payments available through the Sunshine Act shows that the COVID-19 pandemic has significantly impacted industry payments to plastic surgery and its subspecialties. While this study demonstrates the economic impact of the current pandemic, only time will tell whether these trends will persist in the coming years.

Citation impact was highly variable for reporting guidelines of health research: a citation analysis.

OBJECTIVES: Over 400 reporting guidelines are currently published, but the frequency of their use by authors to accurately and transparently report research remains unclear. This study examined citation counts of reporting guidelines and characteristics contributing to their citation impact. STUDY DESIGN AND SETTING: Web of Science database was searched for citation counts of all reporting guidelines with a minimum citation age of 5 years. The total citation impact, mean citation impact and the factors contributing to 2- and 5-year citation rate were established. RESULTS: The search identified 296 articles of reporting guidelines from 1995 to 2013. The mean citations per year was 32.4 (95% confidence interval, 22.3-42.4 citations). The factors associated with 2- and 5-year citation performance of reporting guidelines included the following: open access to the reporting guideline, field of the publishing journal (general vs. specialized medical journal), impact factor of the publishing journal, simultaneous publication in multiple journals, and a male first author. CONCLUSION: The citation rate across reporting guidelines varied with journal impact factor, open access publication, field of the publishing journal, simultaneous publications, and a male first author. Gaps in citations highlight opportunities to increase visibility and encourage author use of reporting guidelines.

Reporting guidelines of health research studies are frequently used inappropriately.

OBJECTIVES: Appropriate use of reporting guidelines of health research ensures that articles present readers with a consistent representation of study relevance, methodology, and results. This study evaluated the use of major reporting guidelines. STUDY DESIGN AND SETTING: A cross-sectional analysis of health research articles citing four major reporting guidelines indexed in the Web of Science Core Collection (up to June 24, 2018). Two independent reviews were performed in a random sample of 200 articles, including clinical trials (N = 50), economic evaluations (N = 50), systematic reviews (N = 50), and animal research studies (N = 50). The use of reporting guidelines to guide the reporting of research studies was considered appropriate. Inappropriate uses included the use of the reporting guidelines as a tool to assess the methodological quality of studies or as a guideline on how to design and conduct the studies. RESULTS: Across all selected reporting guidelines, appropriate use of reporting guidelines was observed in only 39% (95% CI: 32-46%; 78/200) of articles. By contrast, inappropriate use was observed in 41% (95% CI: 34-48%; 82/200), and unclear/other use was observed in 20% (95% CI: 15-26%; 40/200). CONCLUSIONS: Reporting guidelines of health research studies are frequently used inappropriately. Authors may require further education around appropriate use of the reporting guidelines in research reporting.
