BACKGROUND: Prophylactic lymphatic bypass or LYMPHA (LYmphatic Microsurgical Preventive Healing Approach) is increasingly offered to prevent lymphedema following breast cancer treatment, which develops in up to 47% of patients. Previous studies focused on intraoperative and postoperative lymphedema risk factors, which are often unknown preoperatively when the decision to perform LYMPHA is made. This study aims to identify preoperative lymphedema risk factors in the high-risk inflammatory breast cancer (IBC) population. METHODS: Retrospective review of our institution's IBC program database was conducted. The primary outcome was self-reported lymphedema development. Multivariable logistic regression analysis was performed to identify preoperative lymphedema risk factors, while controlling for number of lymph nodes removed during axillary lymph node dissection (ALND), number of positive lymph nodes, residual disease on pathology, and need for adjuvant chemotherapy. RESULTS: Of 356 patients with IBC, 134 (mean age: 51 years, range: 22-89 years) had complete data. All 134 patients underwent surgery and radiation. Forty-seven percent of all 356 patients (167/356) developed lymphedema. Obesity (body mass index > 30) (odds ratio [OR]: 2.7, confidence interval [CI]: 1.2-6.4, p = 0.02) and non-white race (OR: 4.5, CI: 1.2-23, p = 0.04) were preoperative lymphedema risk factors. CONCLUSION: Patients with IBC are high risk for developing lymphedema due to the need for ALND, radiation, and neoadjuvant chemotherapy. This study also identified non-white race and obesity as risk factors. Larger prospective studies should evaluate potential racial disparities in lymphedema development. Due to the high prevalence of lymphedema, LYMPHA should be considered for all patients with IBC.

Dermatologic diseases have a well-documented association with depression and anxiety, which are in turn often comorbid with alcohol use disorder (AUD). Nonethleess, the relationship between dermatologic disease and AUD, and the relative contribution of depression and anxiety, are poorly understood. Here, we utilize the National Insittutes of Health All of Us Research Program to investigate the association between inflammatory and pigmentary dermatologic diseases with AUD. Furthermore, we investigate whether comorbid depression and anxiety mediates this relationship. We employed a matched case-control model with multivariable logistic regression. We also employed a mediation analysis. We found an increased odds of AUD among patients with atopic dermatitis, acne/rosacea, hidradenitis suppurativa, psoriasis, and pigmentary disorders (vitiligo, melasma, and post-inflammatory hyperpigmentation). This was partially mediated by anxiety and depression, especially for diseases with a significant cosmetic component. Overall, these findings highlight the profound psychological and physical health effects that inflammatory and pigmentary disease can have on patients, both independently and in combination with comorbid psychiatric disease.

Osteosarcoma is a rare primary bone tumor for which no significant therapeutic advancement has been made since the late 1980s despite ongoing efforts. Overall, the five-year survival rate remains about 65%, and is much lower in patients with tumors unresponsive to methotrexate, doxorubicin, and cisplatin therapy. Genetic studies have not revealed actionable drug targets, but our group, and others, have reported that epigenomic biomarkers, including regulatory RNAs, may be useful prognostic tools for osteosarcoma. We tested if microRNA (miRNA) transcriptional patterns mark the transition from a chemotherapy sensitive to resistant tumor phenotype. Small RNA sequencing was performed using 14 patient matched pre-chemotherapy biopsy and post-chemotherapy resection high-grade osteosarcoma frozen tumor samples. Independently, small RNA sequencing was performed using 14 patient matched biopsy and resection samples from untreated tumors. Separately, miRNA specific Illumina DASL arrays were used to assay an independent cohort of 65 pre-chemotherapy biopsy and 26 patient matched post-chemotherapy resection formalin fixed paraffin embedded (FFPE) tumor samples. mRNA specific Illumina DASL arrays were used to profile 37 pre-chemotherapy biopsy and five post-chemotherapy resection FFPE samples, all of which were also used for Illumina DASL miRNA profiling. The National Cancer Institute Therapeutically Applicable Research to Generate Effective Treatments dataset, including PCR based miRNA profiling and RNA-seq data for 86 and 93 pre-chemotherapy tumor samples, respectively, was also used. Paired differential expression testing revealed a profile of 17 miRNAs with significantly different transcriptional levels following chemotherapy. Genes targeted by the miRNAs were differentially expressed following chemotherapy, suggesting the miRNAs may regulate transcriptional networks. Finally, an in vitro pharmacogenomic screen using miRNAs and their target transcripts predicted response to a set of candidate small molecule therapeutics which potentially reverse the chemotherapy resistance phenotype and synergize with chemotherapy in otherwise treatment resistant tumors. Importantly, these novel therapeutic targets are distinct from targets identified by a similar pharmacogenomic analysis of previously published prognostic miRNA profiles from pre chemotherapy biopsy specimens.
RESUMO
Many plastic surgery residency programs adapted to the COVID-19 pandemic by implementing virtual grand rounds. This study aimed to assess the impact of virtual grand rounds and how attendees perceived virtual grand rounds to inform future programmatic planning. Methods: This was a quality improvement initiative involving a cross-sectional survey and retrospective review of administrative records for the 2017-2018 (in-person) and 2021-2022 (virtual) academic years for two academic plastic surgery training programs in Boston, MA. Respondents were residents, fellows, and faculty within the two multisite plastic surgery residency training programs. Results: There were 39 respondents (51% faculty, 41% residents, and 8% fellows). There was no evidence of different preferences for the format of future grand rounds (P = 0.08), with most preferring hybrid, defined as in person for speakers and others who could attend. Most respondents indicated a more accessible learning environment (86.8%) and lack of in-person interaction (82.1%) as reasons for liking and not liking virtual grand rounds, respectively. Excluding outliers, attendance in 2021-2022 was on average 7.4% points greater than that in 2017-2018 (P < 0.001), or six to seven more individuals at each session. There were significantly more out-of-state speakers in 2021-2022 (84%) as compared to 2017-2018 (28%) (P = 0.0008). Conclusions: Virtual grand rounds improved attendance and the geographic diversity of speakers. Attendees preferred a hybrid format for future grand rounds, citing advantages and disadvantages to both in-person and virtual formats.
RESUMO
Hidradenitis suppurativa (HS) is a chronic skin disorder characterized by nodules, comedones, and sinus tracts that often leave prominent scarring. In recent years, non-invasive imaging techniques have been used to assess the inflammatory activity, vascularization, and treatment response of lesions. Specifically, fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) scans may aid in identifying systemic inflammation in patients with HS, improving diagnosis. Inflamed hypermetabolic tissues exhibit a greater uptake of FDG due to increased glucose uptake and vascularity. A systematic review was conducted to summarize the utility of nuclear imaging techniques in the diagnosis and treatment follow-up of HS. PubMed, Scopus, and ScienceDirect databases were utilized for relevant articles discussing the utility of PET scans in managing HS. A total of 51 citations were identified in the initial search. Following the review of titles, abstracts, and duplicates, 43 articles were excluded, leaving a total of eight articles for analysis. Data were extracted from each article, encompassing the number of patients, imaging techniques employed, and final results. An analysis of the data demonstrated that FDG-PET showed evidence of identifying subclinical lesions of the disease, improving the visualization of HS, and providing an objective method of assessing severity.
RESUMO
RATIONALE AND OBJECTIVES: To ascertain the perceived obstacles that medical students and Interventional Radiology (IR) residents face performing IR research during training and incorporating research into their future careers. MATERIALS AND METHODS: The study was reviewed and exempt from Institutional Review Board review. Participants' attitudes and perceived barriers toward performing IR research, and experience with mentorship in IR were assessed using a 27-item survey sent to all members of the Society of Interventional Radiology Resident, Fellow and Student (SIR-RFS, n = 445), and Medical Student Council (SIR-MSC, n = 267) sections between July and September 2020. Descriptive statistics were computed for all assessed categorical variables. Fisher's exact tests were performed to measure the significance of association between categorical variables. RESULTS: Of the 712 students and residents surveyed, 151 (â¼21%) responded. Of respondents, 100% reported that conducting research is important to advancing the field of IR. The highest ranked factors and obstacles to performing IR research were increased clinical demands (67.9%), lack of time (46.2%), lack of institutional support (41.5%), and lack of research experience (35.8%). Interestingly, those with a mentor were more likely to report an interest in pursuing a career in IR compared to those without a mentor (98.6% vs 41.0%, p < 0.0001). Furthermore, those with a mentor were more likely to report an interest in pursuing IR research compared to those without a mentor (32.5% vs 14.4%, p < 0.0001). CONCLUSION: There are many obstacles to performing IR research. Strong mentorship is an avenue to address these deterrents. The deployment of mentorship programs in IR is needed to ensure trainees can overcome the barriers outlined in this study and successfully pursue research careers in IR.

Aberrant methylation of genomic DNA has been reported in many cancers. Specific DNA methylation patterns have been shown to provide clinically useful prognostic information and define molecular disease subtypes with different response to therapy and long-term outcome. Osteosarcoma is an aggressive malignancy for which approximately half of tumors recur following standard combined surgical resection and chemotherapy. No accepted prognostic factor save tumor necrosis in response to adjuvant therapy currently exists, and traditional genomic studies have thus far failed to identify meaningful clinical associations. We studied the genome-wide methylation state of primary tumors and tested how they predict patient outcomes. We discovered relative genomic hypomethylation to be strongly predictive of response to standard chemotherapy. Recurrence and survival were also associated with genomic methylation, but through more site-specific patterns. Furthermore, the methylation patterns were reproducible in three small independent clinical datasets. Downstream transcriptional, in vitro, and pharmacogenomic analysis provides insight into the clinical translation of the methylation patterns. Our findings suggest the assessment of genomic methylation may represent a strategy for stratifying patients for the application of alternative therapies.
