The incidence of metabolically unhealthy obesity is rising nationally. In this study, we compare wound and overall complications between metabolically unhealthy obese and healthy patients undergoing elective plastic surgery and model how operative time influences a complication risk.Patients undergoing elective breast and body plastic surgery procedures in the 2009-2019 National Surgical Quality Improvement Program (NSQIP) dataset were identified. Complications were compared between metabolically unhealthy obese (body mass index [BMI]30 with diabetes and/or hypertension) versus metabolically healthy obese patients (BMI30 without diabetes or hypertension). Logistic regression was used to model the probability of wound complications across operative times stratified by metabolic status.Of 139,352 patients, 13.4% (n = 18,663) had metabolically unhealthy obesity and 23.8% (n = 33,135) had metabolically healthy obesity. Compared to metabolically healthy patients, metabolically unhealthy patients had higher incidence of wound complications (6.9% versus 5.6%; P 0.001) and adverse events (12.4% versus 9.6%; P 0.001), in addition to higher 30-d readmission, returns to the operating room, and length of stay (all P 0.001). After adjustment, BMI (Odds ratio [OR] 7.86), hypertension (OR 1.15), and diabetes (OR 1.25) were independent risk factors for wound complications (all P 0.001). Among metabolically unhealthy patients, the operative time was log-linear with a wound complication risk (OR 1.21; P 0.001).Diabetes and hypertension are additive risk factors with obesity for wound complications in elective plastic surgery. Among patients with metabolically unhealthy obesity, a risk of wound complications increases logarithmically with operative time. This distinction with regard to metabolic state might explain the unclear impact of obesity on surgical outcomes within existing surgical literature.

Although breast reconstruction after bilateral mastectomies including a contralateral prophylactic mastectomy is known to have a higher overall complication profile, whether reconstructive complication rates differ between the therapeutic mastectomy and contralateral prophylactic mastectomy sides remains unclear.Women undergoing bilateral mastectomies with autologous or implant-based breast reconstruction for a unilateral breast cancer at a single institution were identified (2009 to 2019). Postoperative complications were stratified by laterality (therapeutic mastectomy versus contralateral prophylactic mastectomy). Paired data were analyzed to compare the risks of complications between prophylactic and therapeutic reconstruction sides in the same patient.A total of 130 patients (260 reconstructions) underwent bilateral autologous or implant-based reconstruction. Although most women underwent a simple mastectomy, a higher proportion of therapeutic mastectomies were modified radical mastectomies including axillary lymph node dissections compared to contralateral prophylactic mastectomies (15.4 percent versus 0 percent). Forty-four percent of women completed postmastectomy radiation therapy of the therapeutic side before definitive reconstruction. Overall, both therapeutic and prophylactic reconstructions had a similar incidence of reconstructive failure (p = 0.57), return to the operating room (p = 0.44), mastectomy skin flap necrosis (p = 0.32), seroma (p = 0.82), fat necrosis (p = 0.16), wound infection (p = 0.56), and cellulitis (p = 0.56). Nearly one-fifth of patients experienced complications limited to the prophylactic side [contralateral prophylactic mastectomy reconstruction complications, n = 26 (20.0 percent); therapeutic mastectomy reconstruction complications, n = 15 (11.5 percent)].Despite a history of local radiation therapy and more extensive oncologic surgery on the therapeutic side, there are no significant differences in the incidence of postsurgical complications on the therapeutic mastectomy and contralateral prophylactic mastectomy sides after bilateral reconstruction.Risk, II.

ChatGPT and similar generative AI have immense potential to revolutionize health care and the field of microsurgery. We found that when it comes to microsurgical procedures, ChatGPT-generated FAQ sheets tend to be highly accurate but somewhat non-specific. At this stage, microsurgeons should read over any ChatGPT-generated patient materials and briefly addend in more specific information while verifying for general accuracy. Overall, it remains to be seen how microsurgeons respond to this exciting new development, to best incorporate ChatGPT in an advantageous yet ethical manner.

Background Timing of surgical intervention is controversial among patients seeking correction of congenital breast deformities. Objectives This study aimed to assess the influence of age on 30-day complications and unplanned healthcare utilization after reconstruction of congenital breast deformities. Methods Female patients undergoing breast reconstruction for congenital breast deformities and Poland syndrome were identified based on International Classification of Diseases (ICD) codes in the 2012 to 2021 pediatric and adult National Surgical Quality Improvement Project (NSQIP) datasets. Complications based on age at correction were compared, and multivariate logistic regression was used to identify predictors of overall and wound healing complications. Results Among 528 patients meeting inclusion criteria, mean (SD) age at surgical correction was 30.2 (13.3) years. Patients most commonly underwent implant placement (50.5%), mastopexy (26.3%), or tissue expander placement (11.6%). Across the cohort, overall incidence of post-operative complications was 4.4%, most commonly superficial surgical site infection (1.0%), reoperation (1.1%) or readmission (1.0%). After multivariate adjustment, increasing age at time of correction was associated with higher incidence of wound complications [odds ratio (OR) 1.001; 95% Confidence Interval (CI) 1.0003-1.002; p = 0.009], in addition to BMI (OR 1.002; 95% CI 1.0007-1.004; p = 0.006) and tobacco use (OR 1.06; 95% CI 1.02-1.11; p = 0.003]. Conclusions Breast reconstruction for congenital breast deformities may be safely undertaken at a young age with a low associated risk of post-operative complications. Large, multi-institutional studies are needed to assess the influence of surgical timing on psychosocial outcomes in this population.

Background Rates of postmastectomy breast reconstruction have been shown to vary by racial, ethnic, and socioeconomic factors. In this study, we evaluated disparities across pathways toward breast reconstruction. Methods All women who underwent mastectomy for breast cancer at a single institution from 2017 to 2018 were reviewed. Rates of discussions about reconstruction with breast surgeons, plastic surgery referrals, plastic surgery consultations, and ultimate decisions to pursue reconstruction were compared by race/ethnicity. Results A total of 218 patients were included, with the racial/ethnic demographic of 56% white, 28% Black, 1% American Indian/Native Alaskan, 4% Asian, and 4% Hispanic/Latina. The overall incidence of postmastectomy breast reconstruction was 48%, which varied by race (white: 58% vs. Black: 34%; p Conclusion Despite statistically equivalent rates of plastic surgery discussions and referrals, black women had lower breast reconstruction rates versus white women. Lower rates of breast reconstruction in Black women likely represent an amalgamation of barriers to care; further exploration within our community is warranted to better understand the racial disparity observed.

Surgical delay is a well-described technique to improve survival of random and pedicled cutaneous flaps. The aim of this study was to test the topical agents minoxidil and iloprost as agents of pharmacologic delay to induce vascular remodeling and decrease overall flap necrosis as an alternative to surgical delay.Seven groups were studied (n = 8 in each group), including the following: vehicle, iloprost, or minoxidil before treatment only; vehicle, iloprost, or minoxidil before and after treatment; and a standard surgical delay group as a positive control. Surgical flaps (caudally based modified McFarlane myocutaneous skin flaps) were elevated after 14 days of pretreatment, reinset isotopically, and observed at various time points until postoperative day 7. Gross viability, histology, Doppler blood flow, perfusion imaging, tissue oxygenation measurement, and vascular casting were performed for analysis.Pharmacologic delay with preoperative application of topical minoxidil or iloprost was found to have comparable flap viability when compared to surgical delay. Significantly increased viability in all treatment groups was observed when compared with vehicle. Continued postoperative treatment with topical agents had no effect on flap viability. The mechanism of improved flap viability was inducible increases in flap blood volume and perfusion rather than the acute vasodilatory effects of the topical agents or decreased flap hypoxia.Preoperative topical application of the vasodilators minoxidil or iloprost improved flap viability comparably to surgical delay. Noninvasive pharmacologic delay may reduce postoperative complications without the need for an additional operation.Preoperative use of topical vasodilators may lead to improved flap viability without the need for a surgical delay procedure. This study may inform future clinical trials examining utility of preoperative topical vasodilators in flap surgery.

IntroductionBreast reconstruction plays an important role for many in restoring form and function of the breast after mastectomy. However, rates of breast reconstruction in the USA vary significantly by race, ethnicity and socioeconomic status. The lower rates of breast reconstruction in non-white women and in women of lower socioeconomic status may reflect a complex interplay between patient and physician factors and access to care. It remains unknown what community-specific barriers may be impacting receipt of breast reconstruction.Methods and analysisThis is a mixed-methods study combining qualitative patient interview data with quantitative practice patterns to develop an actionable plan to address disparities in breast reconstruction in the local community. The primary aims are to (1) capture barriers to breast reconstruction for patients in the local community, (2) quantitatively evaluate practice patterns at the host institution and (3) identify issues and prioritise interventions for change using community-based engagement.Ethics and disseminationEthics approval was obtained at the investigators’ institution. Results from both the quantitative and qualitative portions of the study will be circulated via peer-review publication. These findings will also serve as pilot data for extramural funding to implement and evaluate these proposed solutions.

Breast reconstruction is associated with improved patient well-being after mastectomy; however, factors that contribute to post-surgical dissatisfaction remain poorly characterized. Adult women who underwent post-mastectomy implant-based or autologous breast reconstruction between 2015 and 2019 were recruited to participate in semi-structured interviews regarding their lived experiences with reconstructive care. Participants completed the BREAST-Q, and tabulated scores were used to dichotomize patient-reported outcomes as satisfied or dissatisfied (high or low) for each BREAST-Q domain. A convergent mixed-methods analysis was used to evaluate interviews for content related to satisfaction or dissatisfaction with breast reconstruction. Overall, we interviewed 21 women and identified 17 subcodes that corresponded with the five BREAST-Q domains. Sources of dissatisfaction were found to be related to the following domains: (a) low breast satisfaction due to asymmetry, cup size, and lack of sensation and physical feeling (n = 8, 38%); (b) poor sexual well-being due to shape, look and feel (n = 7, 78% [of 9 who discussed sexual well-being]); (c) reduced physical well-being of the chest due to persistent pain and weakness (n = 11, 52%); (d) reduced abdominal well-being due to changes in abdominal strength, numbness, and posture (n = 6, 38% [of 16 who underwent abdominally based reconstruction]); and (e) low psychosocial well-being impacted by an unexpected appearance that negatively influenced self-confidence and self-identity (n = 13, 62%). Patients may be unprepared for the physical, sexual, and psychosocial outcomes of breast reconstruction. Targeted strategies to improve preoperative education and shared decision making are needed to mitigate unexpectedness associated with breast reconstruction and related outcomes.

BACKGROUND Given the competition in the integrated plastic surgery Match, away rotations are ubiquitous among plastic surgery applicants to differentiate their applications. This study aimed to characterize how performing an away rotation affects rank order and Match outcomes for integrated plastic surgery programs. METHODS An online survey was designed and distributed to the top 25 integrated plastic surgery programs in the United States as determined by Doximity. Programs were polled about away rotation structure, position of rotators on their 2018 to 2019 rank list, and composition of current resident classes. RESULTS Twenty-five programs completed the survey (response rate, 100 percent). On average, programs interviewed 34.9 applicants (range, 22 to 50 applicants) and ranked 32.8 applicants (range, 10 to 50 applicants). Most "ranked-to-match" positions were occupied by home students or away rotators (60.9 percent). Rank order of home students, away rotators, and nonrotators varied significantly (p < 0.001), with median rank order of home students [5 (interquartile range, 1 to 9)] and rotators [14 (interquartile range, 6 to 27)] higher than nonrotators [17 (interquartile range, 10 to 29)]. Rank orders of away rotators tended to follow a bimodal distribution. Furthermore, 64.4 percent of integrated residents were either a home student or away rotator at their matched integrated program, with 20 percent of residency programs composed of greater than 70 percent of away rotators/home students across postgraduate years 1 through 6 classes. CONCLUSIONS For integrated plastic surgery programs, the majority of ranked-to-match students on rank lists and current residents were either home students or away rotators at their respective program. Performing well on an away rotation appears to confer significant benefit to the applicant applying in the integrated plastic surgery Match.

Background While bipedicled free flaps enable increased soft tissue volume and potential for contralateral symmetry in unilateral breast reconstruction, the influence of bipedicled flap reconstruction on patient-reported outcomes remains unclear. Methods Patients undergoing unilateral free flap breast reconstruction at a single institution from 2014 to 2019 were retrospectively reviewed and sent the BREAST-Q and Decision Regret Scale. Complication rates and the BREAST-Q and Decisional Regret Scale scores (0–100) were compared between patients receiving bipedicled total abdominal and unipedicled hemiabdominal free flaps. Results Sixty-five patients undergoing unilateral breast reconstruction completed the BREAST-Q and Decision Regret Scale with median (interquartile range [IQR]) follow-up time of 32 [22–55] months. Compared with bipedicled flaps, patients receiving unipedicled hemiabdominal flaps had higher mean body mass index (BMI; p = 0.009) and higher incidence of fat grafting (p = 0.03) and contralateral reduction mammaplasties (p = 0.03). There was no difference in incidence of major or minor complications, abdominal hernias or bulges, or total operative time between bipedicled and unipedicled flaps (p > 0.05). Overall, BREAST-Q scores for satisfaction with breast, sexual wellbeing, psychosocial wellbeing, physical wellbeing (chest), and physical wellbeing (abdomen) and the Decision Regret Scale scores did not significantly vary between bipedicled and unipedicled reconstructions (all p > 0.05). However, among large-breasted patients (≥C cup), mean (standard deviation [SD]) sexual wellbeing was significantly higher after bipedicled total abdominal free flap reconstruction ([60.2 (23.3) vs. 46.2 (22.0)]; p = 0.04), though this difference did not reach significance after multivariate adjustment. Conclusion Unilateral breast reconstruction with bipedicled total abdominal free flaps results in similar complication risk, patient satisfaction, and decisional regret without the need for as many contralateral reduction procedures.

There is a lack of consensus detailing the optimal approach to free-flap breast reconstruction when considering immediate, delayed, or staged techniques. This study compared costs, complications, and healthcare resource utilization (HCRU) across staged, delayed, and immediate free-flap breast reconstruction.Retrospective study using MarketScan databases to identify women who underwent mastectomies and free-flap reconstructions between 2014 and 2018. Complications, costs, and HCRU [readmission, reoperation, emergency department (ED) visits] occurring 90 days after mastectomy and 90 days after free flap were compared across immediate, delayed, and staged reconstruction.Of 3310 women identified, 69.8% underwent immediate, 11.7% underwent delayed, and 18.5% underwent staged free-flap reconstruction. Staged reconstruction was associated with the highest rate (57.8% staged, 42.3% delayed, 32.0% immediate; p0.001) and adjusted relative risk [67% higher than immediate (95% CI: 49-87%; p0.001)] of surgical complications. Staged displayed the highest HCRU (staged 47.9%, delayed, 38.4%, immediate 25.2%; p0.001), with 16.5%, 30.7%, and 26.5% of staged patients experiencing readmission, reoperation, or ED visit, respectively. The adjusted probability of HCRU was 206% higher (95% CI: 156-266%; p0.001) for staged compared with immediate. Staged had the highest mean total cost (staged $106,443, delayed $80,667, immediate $76,756; p0.001) with regression demonstrating the adjusted mean cost for staged is 31% higher (95% CI: 23-39%; p0.001) when compared with immediate.Staged free-flap reconstruction is associated with increased complications, costs, and HCRU, while immediate demonstrated the lowest. The potential esthetic benefits of a staged approach should be balanced with the increased risk for adverse events after surgery.

Targeted muscle reinnervation has emerged as a technique to reduce neuroma and phantom limb pain after below-knee amputation; however, the incidence of postoperative complications remains unknown. This multi-institutional study assessed the risk of postoperative complications among patients who underwent targeted muscle reinnervation at the time of below-knee amputation.Patients who underwent below-knee amputation with targeted muscle reinnervation were propensity score-matched 1:3 to patients who underwent below-knee amputation alone. Study outcomes included the incidence of major or minor complications within 60 days. Regression models were used to estimate the relative risk of major and minor complications.Overall, 96 patients were matched, including 31 patients who had below-knee amputation with targeted muscle reinnervation and 65 who had below-knee amputation alone. In the matched sample, a higher incidence of major complications (29 percent versus 24.6 percent), readmission (25.8 percent versus 18.5 percent), and reoperation (19.4 percent versus 10.8 percent) was seen after both procedures compared with below-knee amputation alone. Patients who underwent both procedures displayed a higher incidence of minor complications (25.8 percent versus 20.0 percent), blood transfusion (22.6 percent versus 18.5 percent), and wound healing complications (45.2 percent versus 33.8 percent) and longer operative time (mean ± SD, 188.5 ± 63.6 minutes versus 88 ± 28.2 minutes). There was no statistically significant difference in the risk of major (relative risk, 1.20; 90 percent CI, 0.68, 2.11) or minor (relative risk, 1.21; 90 percent CI, 0.61, 2.41) complications between the two cohorts.Despite an increased incidence of postoperative complications, undergoing below-knee amputation with targeted muscle reinnervation does not confer a statistically significant increased risk of major or minor complications. Future studies are needed to delineate patient selection criteria when assessing the suitability of targeted muscle reinnervation at the time of major limb amputation.Therapeutic, III.

Background Psychosocial distress, depression, or anxiety can occur in up to 50% of women after a breast cancer diagnosis and mastectomy. The purpose of this study was to assess the potential benefit of lavender oil as a perioperative adjunct to improve anxiety, depression, pain, and sleep in women undergoing microvascular breast reconstruction. Methods This was a prospective, single-blinded, randomized, controlled trial of 49 patients undergoing microvascular breast reconstruction. Patients were randomized to receive lavender oil or placebo (coconut oil) throughout their hospitalization. The effect of lavender oil on perioperative stress, anxiety, depression, sleep, and pain was measured using the hospital anxiety and depression scale, Richards–Campbell Sleep Questionnaire, and the visual analogue scale. Results Twenty-seven patients were assigned to the lavender group and 22 patients were assigned to the control group. No significant differences were seen in the perioperative setting between the groups with regard to anxiety (p = 0.82), depression (p = 0.21), sleep (p = 0.86), or pain (p = 0.30) scores. No adverse events (i.e., allergic reaction) were captured, and no significant differences in surgery-related complications were observed. When evaluating the entire cohort, postoperative anxiety scores were significantly lower than preoperative scores (p Conclusion In the setting of microvascular breast reconstruction, lavender oil and aromatherapy had no significant adverse events or complications; however, there were no measurable advantages pertaining to metrics of depression, anxiety, sleep, or pain as compared with the control group.

Limited visibility characteristic of cleft palate repair presents both ergonomic and educational challenges to cleft surgeons. Despite widespread recognition and reporting, posture-related spine disorders continue to represent a significant and potentially career-limiting problem for cleft/craniofacial surgeons. In addition, education and participation during palate repairs is difficult because of visual field constraints. At the authors' institution, a novel videoscope system was designed and implemented to (1) provide visualization for all surgical team members during palate operations, (2) facilitate active resident education, and (3) improve surgeon ergonomics. The authors' prior report demonstrated proof of concept for this method, which is now used in all cleft palate operations at their center. The purpose of this report is to share the detailed methodology to facilitate implementation by others and a retrospective review of the authors' experience before and after implementation. Video demonstration of the videoscope setup and a representative, recorded case are provided. The use of the videoscope was feasible in palatoplasties regardless of palatal phenotype and repair technique and did not have an effect on operative time. Subjectively, the authors report reduced procedure time in cervical flexion and subjectively improved musculoskeletal strain associated with videoscope use. Importantly, use of this system also provided complete visualization for all operating room team members and enabled enhanced resident autonomy during palate operations. Finally, it has facilitated the creation and archive of high-definition educational videos with unparalleled perspective. The equipment required to implement the system is likely already available in many medical centers. Adoption of this system may provide an opportunity to improve posture and teaching capabilities for cleft surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, III.

OBJECTIVE: We aim to identify prognostic groups within a de novo metastatic cohort, incorporating both anatomic and biologic factors. BACKGROUND: Staging for breast cancer now includes anatomic and biologic factors, although the guidelines for stage IV disease do not account for how these factors may influence outcomes. METHODS: Adults with de novo metastatic breast cancer were selected from the National Cancer DataBase (2010–2013). Recursive partitioning analysis was used to group patients with similar overall survival (OS) based on clinical T/N stage, tumor grade, ER, PR, HER2, number of metastatic sites, and presence of bone-only metastases. Categories were created by amalgamating homogeneous groups based on 3-year OS rates (stage IVA: >50%, stage IVB: 30%–50%, stage IVC: 1) as the first stratification point, and ER status as the second stratification point for both resulting groups. Additional divisions were made based on HER2 status, PR status, cT stage, tumor grade, and presence of bone-only metastases. After bootstrapping, significant differences in 3-year OS were noted between the 3 groups [stage IVB vs IVA: HR 1.58 (95% confidence interval 1.50–1.67), stage IVC vs IVA: HR 3.54 (95% confidence interval 3.33–3.77)]. CONCLUSIONS: Both anatomic and biologic factors yielded reliable and reproducible prognostic estimates among patients with metastatic disease. These findings support formal stratification of de novo stage IV breast cancer into 3 distinct prognosis groups.

Background Limb-threatening lower extremity traumatic injuries can be devastating events with a multifaceted impact on patients. Therefore, evaluating patient-reported outcomes (PROs) in addition to traditional surgical outcomes is important. However, currently available instruments are limited as they were not developed specific to lower extremity trauma patients and lack content validity. The LIMB-Q is being developed as a novel PRO instrument to meet this need, with the goal to measure all relevant concepts and issues impacting amputation and limb-salvage patients after limb-threatening lower extremity trauma. Methods This is a qualitative interview-based study evaluating content validity for the LIMB-Q. Patients aged 18 years and older who underwent amputation, reconstruction, or amputation after failed reconstruction were recruited using purposeful sampling to maximize variability of participant experiences. Expert opinion was solicited from a variety of clinical providers and qualitative researchers internationally. Preliminary items and scales were modified, added, or removed based on participant and expert feedback after each round of participant interviews and expert opinion. Results Twelve patients and 43 experts provided feedback in a total of three rounds, with changes to the preliminary instrument made between each round. One scale was dropped after round one, one scale was added after round two, and only minor changes were needed after round three. Modifications, additions and removal of items, instructions, and response options were made after each round using feedback gathered. Conclusion The LIMB-Q was refined and modified to reflect feedback from patients and experts in the field. Content validity for the LIMB-Q was established. Following a large-scale field test, the LIMB-Q will be ready for use in research and clinical care.

Step 1 will transition to a pass/fail system in 2022. This study aimed to characterize the effects of this change on integrated plastic surgery program directors' selection criteria and assess whether Step 2 Clinical Knowledge (CK) can replace Step 1 as an application selection metric.Online survey that was administered to a collaborative group of ten plastic surgery program directors collecting USMLE Step 1, Step 2 CK, In-Service, and written board scores for 3 years of graduated integrated residents.Ten academic integrated plastic surgery programs.Data from 80 graduated integrated plastic surgery residents.Across 80 included integrated residents, mean (SD) Step 1 score was 247 (13), Step 2 CK was 249 (13), PGY1-6 In-Service percentiles varied from 45 to 53 percentile, and written board pass rate was 98.3%. Both Step 1 and Step 2 CK correlated highly with In-Service percentiles (both p0.001), with Step 2 CK scores correlating similarly with In-Service performance compared to Step 1 (rho 0.359 vs. 0.355, respectively). Across applicant characteristics, program directors reported the highest relative increase in Step 2 CK importance after Step 1 transitions to pass/fail.Step 2 CK correlates similarly with plastic surgery In-Service performance compared to Step 1. While Step scores do not necessarily correlate with residency performance, Step 2 CK may also be used as an application screening metric for programs seeking objective data to differentiate plastic surgery applicants.

OBJECTIVES: Chronic pain affects a significant number of patients following hernia repair, ranging from 11 to 54% in the literature. The aim of this study was to assess the prevalence, overall costs and health care utilization associated with chronic pain after hernia repair. MATERIALS AND METHODS: A retrospective longitudinal study was performed using the Truven MarketScan(®) database to identify patients who develop chronic neuropathic post-hernia repair pain from 2001 to 2012. Patients were grouped into Chronic Pain (CP) and No Chronic Pain (No CP) cohorts. Patients were excluded if they 1) were under 18 years of age 2) had a previous pain diagnosis 3) had chronic pain diagnosed

Background We aim to determine clinical and pathological stage discordance rates and to evaluate factors associated with discordance. Methods Adults with clinical stages I-III breast cancer were identified from the National Cancer Data Base. Concordance was defined as cTN = pTN (discordance: cTN≠pTN). Multivariate logistic regression was used to identify factors associated with discordance. Results Comparing clinical and pathological stage, 23.1% were downstaged and 8.7% were upstaged. After adjustment, factors associated with downstaging (vs concordance) included grade 3 (OR 10.56, vs grade 1) and HER2-negative (OR 3.79). Factors associated with upstaging (vs concordance) were grade 3 (OR 10.56, vs grade 1), HER2-negative (OR 1.25), and lobular histology (OR 2.47, vs ductal). ER-negative status was associated with stage concordance (vs downstaged or upstaged, OR 0.52 and 0.87). Conclusions Among breast cancer patients, nearly one-third exhibit clinical-pathological stage discordance. This high likelihood of discordance is important to consider for counseling and treatment planning.

Marital status is known to influence quality of life, survival, and treatment decision-making after breast cancer diagnosis. We aimed to determine whether relationship status impacts contemporary patterns of immediate breast reconstruction.Surveillance, Epidemiology, and End Results (SEER)-18 was used to identify females undergoing mastectomy for stage 0-III breast cancer from 1998 to 2014. Multivariate logistic regression was used to estimate the association of relationship status with the likelihood of postmastectomy reconstruction. Patients were grouped by diagnosis year to assess change in the reconstructed population with time. Among younger patients ≤45 years, a generalized logistic model was used to predict reconstruction subtype.Among 346,418 patients, reconstruction after mastectomy was more likely to occur in women with relationship support in the form of a marriage or partner [odds ratio (OR) 1.31; 95% confidence interval (CI), 1.28-1.34; p0.001]. Women who were separated (OR 0.76), single (OR 0.73), or widowed (OR 0.56) were significantly less likely than married women to undergo reconstruction (all p0.001). During the 17-year study period, change in reconstruction rates with time varied by relationship status (interaction p=0.02), with reconstruction rates among divorced patients increasing more slowly than those among married and partnered women. Among younger women, subtype patterns varied by relationship status (p=0.004), with divorced women less likely to receive autologous over implant reconstruction (OR 0.87; p = 0.03).Relationship status may influence decision-making regarding pursuit and type of postmastectomy reconstruction. Consideration of support networks of patients with breast cancer could facilitate tailored preoperative counseling by reconstructive surgeons.

The hypoxia-inducible factor (HIF) pathway, regulated by prolyl hydroxylase, is central to tissue adaptation to ischemia. The authors tested whether the prolyl hydroxylase inhibitor dimethyloxalylglycine reduces skin flap necrosis.Dorsal skin flaps were raised on hairless rats, with dimethyloxalylglycine delivered intraperitoneally and/or topically for 7 days before and after surgery. After 14 treatment days, percentage of flap necrosis was compared grossly and tissue perfusion compared with an in vivo imaging system. Angiogenesis was compared using immunohistochemical CD31 staining and enzyme-linked immunosorbent assay for tissue vascular endothelial growth factor. Expression levels of HIF-1α and terminal deoxynucleotidyl transferase-mediated dUDP end-labeling were compared using immunohistochemical staining. Complete blood counts and gross necropsy specimens were obtained to assess systemic toxicity.Dimethyloxalylglycine administration significantly improved postoperative flap viability, with combined topical and intraperitoneal dimethyloxalylglycine administration leading to reduced necrosis on postsurgical day 7 at 6 mg/kg/day, 12 mg/kg/day, 24 mg/kg/day, and 48 mg/kg/day versus controls (all p0.05). Compared with controls (unperfused, 39.9 ± 3.8 percent), dimethyloxalylglycine treatment led to a dose-dependent decrease in unperfused tissue at 6 mg/kg/day (11.4 ± 1.7 percent), 12 mg/kg/day (9.4 ± 4.2 percent), 24 mg/kg/day (4.7 ± 2.6 percent), and 48 mg/kg/day (1.4 ± 0.9 percent) (all p0.001). Topical dimethyloxalylglycine application alone administered at 48 mg/kg/day was sufficient to improve flap viability (p = 0.005). Dimethyloxalylglycine-treated flaps exhibited higher CD31 staining (p = 0.004), tissue vascular endothelial growth factor (p = 0.007), HIF-1α staining (p0.001), and reduced terminal deoxynucleotidyl transferase-mediated dUDP end-labeling staining (p = 0.045). There were no differences in hematocrit or macroscopic organ changes on gross necropsy.Topical and systemic targeting of the HIF-1 pathway may be a promising therapeutic approach to improve flap resistance to ischemia.

Background: For complex surgery, intraoperative ketamine administration is readily used to reduce post-operative pain. However, there have been a few studies suggesting that intraoperative ketamine may have deleterious effects and impact post-operative delirium. Therefore, we sought to identify the impact that intraoperative ketamine has on post-operative outcomes after complex spinal surgery involving ≥5 level fusions. Methods: The medical records of 138 adult (≥18 years old) spine deformity patients undergoing elective, primary complex spinal fusion (≥5 level) for deformity correction at a major academic institution from 2010 to 2015 were reviewed. We identified 98 (71.0%) who had intraoperative ketamine administration and 40 (29%) who did not (Ketamine-Use: n=98; No-Ketamine: n=40). Patient demographics, comorbidities, intra- and post-operative complication rates were collected for each patient. The primary outcome investigated in this study was the rate of post-operative delirium. A multivariate nominal-logistic regression analysis was used to determine the independent association between intraoperative ketamine and post-operative delirium. Results: Patient demographics and comorbidities were similar between both cohorts, including age, gender, and BMI. The median number of fusion levels operated, length of surgery, estimated blood loss, and proportion of patients requiring blood transfusions were similar between both cohorts. Postoperative complication profile was similar between the cohorts, except for the Ketamine-Use cohort having significantly higher proportion of patients experiencing delirium (Ketamine-Use: 14.3% vs . No-Ketamine: 2.6%, P=0.047). In a multivariate nominal-logistic regression analysis, intraoperative Ketamine-Use was independently associated with post-operative delirium (OR: 9.475, 95% CI: 1.026–87.508, P=0.047). Conclusions: Our study suggests that the intraoperative use of ketamine may increase the risk of post-operative delirium. Further studies are necessary to understand the physiological effect intraoperative ketamine has on patients undergoing complex spinal fusions in order to better overall patient care and reduce healthcare resources.

OBJECTIVEIn the United States, healthcare expenditures have been soaring at a concerning rate. There has been an excessive use of postoperative radiographs after spine surgery and this has been a target for hospitals to reduce unnecessary costs. However, there are only limited data identifying the rate of instrumentation changes on radiographs after complex spine surgery involving ≥ 5-level fusions.METHODSThe medical records of 136 adult (≥ 18 years old) patients with spine deformity undergoing elective, primary complex spinal fusion (≥ 5 levels) for deformity correction at a major academic institution between 2010 and 2015 were reviewed. Patient demographics, comorbidities, and intra- and postoperative complication rates were collected for each patient. The authors reviewed the first 5 subsequent postoperative and follow-up radiographs, and determined whether revision of surgery was performed within 5 years postoperatively. The primary outcome investigated in this study was the rate of hardware changes on follow-up radiographs.RESULTSThe majority of patients were female, with a mean age of 53.8 ± 20.0 years and a body mass index of 27.3 ± 6.2 kg/m2 (parametric data are expressed as the mean ± SD). The median number of fusion levels was 9 (interquartile range 7–13), with a mean length of surgery of 327.8 ± 124.7 minutes and an estimated blood loss of 1312.1 ± 1269.2 ml. The mean length of hospital stay was 6.6 ± 3.9 days, with a 30-day readmission rate of 14.0%. Postoperative and follow-up change in stability on radiographs (days from operation) included: image 1 (4.6 ± 9.3 days) 0.0%; image 2 (51.7 ± 49.9 days) 3.0%; image 3 (142.1 ± 179.8 days) 5.6%; image 4 (277.3 ± 272.5 days) 11.3%; and image 5 (463.1 ± 525.9 days) 15.7%. The 3rd year after surgery had the highest rate of hardware revision (5.55%), followed by the 2nd year (4.68%), and the 1st year (4.54%).CONCLUSIONSThis study suggests that the rate of instrumentation changes on radiographs increases over time, with no changes occurring at the first postoperative image. In an era of cost-conscious healthcare, fewer orders for early radiographs after complex spinal fusions (≥ 5 levels) may not impact patient care and can reduce the overall use of healthcare resources.
