RESUMEN

BACKGROUND: This study aims to compare perfusion dynamics using indocyanine green videoangiography before and after the creation of a second venous anastomosis between the superficial inferior epigastric vein and the retrograde internal mammary vein (IMV) in deep inferior epigastric perforator (DIEP) flap breast reconstructions. METHODS: Indocyanine green videoangiography performed during DIEP flap reconstructions was analyzed prospectively. The areas of interest were above the perforators with the highest intensity (complete perfusion), the most distal lateral edge of the flap (partial perfusion), and the next lowest intensity (ischemic). We compared the zone intensities before and after the second venous anastomosis, assessing venous drainage patency and functionality. Patient characteristics, operative details, and complications were collected. RESULTS: Seven patients (10 breasts) underwent DIEP reconstruction. Mean age was 54.5 ± 12.4 years. Mean operative duration was 575.5 ± 172.6 minutes. Donors included DIEV (n = 10, 100.0%), superficial inferior epigastric vein (n = 9, 90.0%), and superficial circumflex epigastric vein (n = 1, 10.0%). All DIEVs were anastomosed to the antegrade IMV (n = 10, 100.0%). Superficial inferior epigastric veins were anastomosed to the retrograde IMV (n = 10, 100.0%). Mean peak intensities of the complete perfusion zone before and after the second venous anastomosis were 160.7 ± 42.1 and 188 ± 42.1, respectively (P = 0.163). Mean peak intensities of the partial perfusion zone were 100.8 ± 21.5 and 152 ± 31.5, respectively (P < 0.001). Mean peak intensities of the ischemic zone were 90.4 ± 37.4 and 143.4 ± 45.3, respectively (P = 0.012). CONCLUSION: These findings highlight the potential benefits of the super drainage technique in enhancing perfusion and reducing complications, emphasizing the need for further investigation and consideration of this technique in clinical practice.

RESUMEN

BACKGROUND: Acellular dermal matrices (ADMs) are frequently employed in immediate prosthesis-based breast reconstruction (iPBR) to provide structural support. Despite differences in ADM derivatives, few studies directly compare their outcomes in the setting of iPBR. We sought to conduct a large head-to-head study comparing 3 ADMs used across our institution. METHODS: A multicenter retrospective review of patients undergoing iPBR with SurgiMend PRS (fetal bovine-derived; Integra Lifesciences, Princeton, NJ), AlloDerm (human-derived; LifeCell Corp, Bridgewater, NJ), or DermACELL (human-derived; Stryker Corp, Kalamazoo, MI) between January 2014 to July 2022 was performed. Primary outcomes included rates of unplanned explantation and total reconstructive failure. Secondary outcomes included 90-day postoperative complications and long-term rates of capsular contracture development. RESULTS: A total of 738 patients (1228 breasts) underwent iPBR during the study period; 405 patients received DermACELL (54.9%), 231 received AlloDerm (31.3%), and 102 received SurgiMend PRS (13.8%). Rates of short-term complications, total reconstruction failure, reoperation within 90 days, capsular contracture, and unplanned explantation were comparable. These findings remained true upon multivariate analysis accounting for baseline differences between cohorts, whereby ADM type was not an independent predictor of any outcome of interest. Conversely, factors such as body mass index, diabetes mellitus, smoking history, neoadjuvant and adjuvant chemotherapy, adjuvant radiation, skin-sparing mastectomy, Wise pattern and periareolar incisions, use of tissue expanders, and a subpectoral plane of insertion were significant predictors of postoperative complications. CONCLUSION: Low rates of complications support the equivalency of fetal bovine and human-derived ADMs in iPBR. Patient characteristics and operative approach are likely more predictive of postoperative outcomes than ADM derivative alone.

RESUMEN

Hypercholesterolemia is frequently intertwined with hepatosteatosis, hypertriglyceridemia, and hyperglycemia. This study is designed to assess the therapeutic efficacy of miR-206 in contrast to statins in the context of managing hypercholesterolemia in mice. We previously showed that miR-206 is a potent inhibitor of de novo lipogenesis (DNL), cholesterol synthesis and gluconeogenesis in mice. Given that these processes occur within hepatocytes, we employed a mini-circle (MC) system to deliver miR-206 specifically to hepatocytes (designated as MC-miR-206). A single intravenous injection of MC-miR-206 maintained high levels of miR-206 in the liver for at least two weeks, thereby maintaining suppression of hepatic DNL, cholesterol synthesis and gluconeogenesis. MC-miR-206 significantly reduced DNA damage, endoplasmic reticulum and oxidative stress, and hepatic toxicity. Therapeutically, both MC-miR-206 and statins significantly reduced total serum cholesterol and triglycerides as well as LDL cholesterol and VLDL cholesterol in mice maintained on the normal chow and high-fat high-cholesterol diet. MC-miR-206 reduced liver weight, hepatic triglycerides and cholesterol and blood glucose, while statins slightly increased hepatic cholesterol and blood glucose and failed to affect levels of liver weight and hepatic triglycerides. Mechanistically, miR-206 alleviated hypercholesterolemia by inhibiting hepatic cholesterol synthesis, while statins increased HMGCR activity, hepatic cholesterol synthesis and fecal neutral steroid excretion. CONCLUSIONS: MiR-206 facilitates the regression of hypercholesterolemia, hypertriglyceridemia, hyperglycemia, and hepatosteatosis. MiR-206 outperforms statins by reducing hyperglycemia, hepatic cholesterol levels, and hepatic toxicity.

RESUMEN

BACKGROUND: Anemia is associated with worse clinical outcomes in cardiac patients. We aim to investigate the clinical outcomes and readmission rates in anemic patients undergoing transcatheter edge-to-edge repair (TEER) for severe mitral valve regurgitation (MR). METHODS: The National Readmissions Database (NRD) from 2015 to 2018 was queried using the ICD-10 codes to identify patients admitted for TEER. Patients were divided into anemic and non-anemic sub-groups. Univariate and multivariate analyses were performed. Cardiovascular outcomes were assessed between cohorts at index admission and readmissions at 30, 90, and 180 days. STATA v.17 was used for analysis (StataCorp LLC, Texas, USA). RESULTS: Our final cohort included 28,995 patients who had undergone TEER in the United States between 2016 and 2019. About 1,434 (4.9%) had a diagnosis of anemia. The mean age of patients who had TEER with anemia and TEER without anemia was 76.9 ± 10.8 vs. 77.7 ± 10.2, respectively. In the adjusted model, anemic patients had higher odds of acute kidney injury (AKI) (aOR 2.21; 95% [CI 1.81-2.6; p<0.001]), HF (aOR 1.75; 95% [CI 1.28-2.3; p<0.001]), myocardial infarction (MI) (aOR 1.54; 95% [CI 1.01-2.33; p<0.041]), major adverse cardiac and cerebrovascular events (MACCE) (aOR 1.72; 95% [CI 1.2-9-2.3; p<0.001]), and net adverse event (aOR 1.85; 95% [CI 1.32-2.59; p<0.001]). The anemic group's readmission rate was overall higher at 30, 90, and 180 days from 2016 to 2019. CONCLUSION: Anemia was associated with increased adverse clinical outcomes and more extended hospital stays in patients with anemia who had undergone TEER procedures compared to the non-anemic group.

RESUMEN

Ribonucleotide reductases (RNRs) are essential enzymes that catalyze the de novo transformation of nucleoside 5'-di(tri)phosphates [ND(T)Ps, where N is A, U, C, or G] to their corresponding deoxynucleotides. Despite the diversity of factors required for function and the low sequence conservation across RNRs, a unifying apparatus consolidating RNR activity is explored. We combine aspects of the protein subunit simplicity of class II RNR with a modified version of Escherichia coli class la photoRNRs that initiate radical chemistry with light to engineer a mimic of a class II enzyme. The design of this RNR involves fusing a truncated form of the active site containing α subunit with the functionally important C-terminal tail of the radical-generating ß subunit to render a chimeric RNR. Inspired by a recent cryo-EM structure, a [Re] photooxidant is located adjacent to Y356[ß], which is an essential component of the radical transport pathway in class I RNRs. Combination of this RNR photochimera with cytidine diphosphate (CDP), adenosine triphosphate (ATP), and light resulted in the generation of Y356• along with production of deoxycytidine diphosphate (dCDP) and cytosine. The photoproducts reflect an active site chemistry consistent with both the consensus mechanism of RNR and chemistry observed when RNR is inactivated by mechanism-based inhibitors in the active site. The enzymatic activity of the RNR photochimera in the absence of any ß metallocofactor highlights the adaptability of the 10-stranded αß barrel finger loop to support deoxynucleotide formation and accommodate the design of engineered RNRs.

RESUMEN

Purpose: This study investigates gender-based disparities in health-related quality of life (HRQOL) outcomes among kidney stone patients and explores potential contributing factors. Methods: A retrospective review of medical records at the University of Rochester Medical Center was conducted on 2199 new urolithiasis patients who completed the Wisconsin Stone Quality of Life Questionnaire (WISQOL) standardized on a 0 to 100 scale. Demographic and clinical data were collected. Statistical analyses included univariate tests, chi-squared tests, and multivariate linear regression. Results: Of the 2199 kidney stone patients, 1085 (49.3%) were women. Women reported significantly lower quality of life (QoL) scores compared with men (71.6 vs 80.7; p < 0.001), and this persisted across all domains, including social impact (80.2 vs 86.9; p < 0.001), emotional impact (67.3 vs 77.1; p < 0.001), disease impact (67.3 vs 77.1; p < 0.001), and impact vitality (62.6 vs 72.9; p < 0.001). Female gender was identified as an independent predictor of diminished QoL scores, along with younger age, symptomatic status, number of surgeries, and presence of a psychosocial comorbidity. Conclusions: Our findings suggest that women with kidney stones experience lower HRQOL compared with men, even accounting for clinical and demographic factors. Although this study provides preliminary insights, additional research is needed to validate these findings in broader and more varied populations.

RESUMEN

Papillary muscle rupture is usually caused by myocardial infarction although rare cases of non-ischemic etiology have also been described. Among these, infective endocarditis represents an important cause. Herein, we report a case due to Streptococcus agalactiae involving the posteromedial papillary muscle. Learning objective: Non-ischemic papillary muscle rupture should be suspected when there is no evidence of atherosclerotic coronary artery disease. In the febrile patient, infective endocarditis should be considered in the differential diagnosis.

RESUMEN

BACKGROUND: Autologous breast reconstruction confers favorable patient reports of satisfaction and quality of life compared to implant-based reconstruction over a lifetime. The latissimus dorsi with immediate fat transfer (LIFT) is an alternative approach to abdominally based free flaps (Ab-FF), which expands fully autologous reconstruction to non-microsurgeons. This study aims to compare the two procedures concerning their clinical and patient-reported outcomes one year postoperatively. METHODS: We conducted a retrospective review of LIFTs and Ab-FFs performed between March 2017 and August 2022. The primary outcomes were postoperative complications, reoperations, and longitudinal BREAST-Q scores. BREAST-Q modules included Satisfaction with Breasts, Abdomen, Back, Psychosocial Well-being, Physical Well-being: Chest, Abdomen, Back, and Sexual Well-being. RESULTS: Of the 281 included patients (408 breasts), 211 received Ab-FF, and 70 received LIFT. One-year follow-up (median [IQR]: 12 [12] months) demonstrated that Ab-FF independently predicted dehiscence, reoperation procedures, and revisional surgery. LIFT independently increased the odds of seroma. In addition, obesity predicted dehiscence, while bilateral reconstructions predicted revisional fat grafting. BREAST-Q scores fluctuated over time but were similar across all measured domains by one year postoperatively. CONCLUSIONS: Although Ab-FF is the gold-standard approach for fully autologous reconstruction, LIFT procedures may be associated with a less complicated postoperative course while eliciting similar patient-reported outcomes. LIFT may subsequently be preferred to limit postoperative complications, particularly in patients with obesity. LIFT can also be utilized by more plastic surgeons who are either not microsurgically trained or do not have an environment that fosters Ab-FF.

RESUMEN

The global epidemiological transition of atherosclerotic vascular diseases is witnessing a rapid redistribution of its burden, shifting from high-income to low- and middle-income countries. With a wide clinical spectrum, spanning from intermittent claudication to more complex critical limb threatening ischemia, nonhealing ulcers, gangrene as well as acute limb ischemia, peripheral artery disease is often faced with the challenges of under-diagnosis and under-treatment despite its high prevalence. The management of peripheral arterial disease in patients with multiple comorbidities presents a formidable challenge and remains a pressing global health concern. In this review, we aim to provide an in-depth overview of the pathophysiology of peripheral artery disease and explore evidence-based management strategies encompassing pharmacological, lifestyle, interventional, and surgical approaches. By addressing these challenges, the review contributes to a better understanding of the evolving landscape of peripheral artery disease, offering insights into effective and holistic management strategies.

RESUMEN

INTRODUCTION: Although nipple-sparing mastectomy (NSM) and immediate breast reconstruction (IBR) have long been praised for excellent cosmetic results and the resultant psychosocial benefits, the feasibility and safety of these procedures in patients older than 60 years have yet to be demonstrated in a large population. METHODS: Patients undergoing NSM with or without IBR at the MedStar Georgetown University Hospital between 1998 and 2017 were included. Patient demographics, surgical intervention, and complication and recurrence events were retrieved from electronic medical records. Primary outcomes were recurrence and complication rates by age groups older and younger than 60 years. RESULTS: There were 673 breasts from 397 patients; 58 (8.6%) older than 60 years and 615 (91.4%) younger than 60 years with mean follow-up of 5.43 (0.12) years. The mean age for those older than 60 was 63.9 (3.3) years, whereas that for those younger than 60 was 43.1 (7.9) years (P < 0.001). The older than 60 group had significantly higher prevalence of diabetes, rates of therapeutic (vs prophylactic) and unilateral (vs bilateral) NSM, and mastectomy weight. However, there were no significant differences by age group in complication rates or increased risk of locoregional or distant recurrence with age. CONCLUSIONS: Based on similar complication profiles in both age groups, we demonstrate safety and feasibility of both NSM and IBR in the aging population. Despite increased age and comorbidity status, appropriately selected older women were able to achieve similar outcomes to younger women undergoing NSM with or without IBR.

RESUMEN

BACKGROUND: Aspiration thrombectomy has gained popularity in patients with massive and sub-massive pulmonary embolism (PE) and having contraindications to thrombolysis. METHODS: A meta-analysis was conducted including studies on aspiration thrombectomy in patients with high-risk and intermediate-risk PE. The pooled odds ratio for efficacy parameters, including change in heart rate, blood pressure and right ventricle/left ventricle (RV/LV) ratio, and safety parameters including major bleeding and stroke, was calculated using a random effects model. RESULTS: The meta-analysis of 24 selected studies revealed that intermediate and high-risk pulmonary embolism (PE) patients demonstrated significant improvements: modified Miller score odds ratio of 10.60, mean pulmonary artery pressure reduction by 0.04 mm Hg, and an overall all-cause mortality odds ratio of 0.10. Considerable heterogeneity was observed in various outcomes. CONCLUSION: Aspiration thrombectomy has success rates in both high-risk and intermediate-risk PE, however, procedural risks, including bleeding, must be anticipated.

RESUMEN

Limited data are available regarding in-hospital outcomes of transcatheter aortic valve implantation (TAVI) in the octogenarian population with chronic kidney disease (CKD). We sought to study the cardiovascular outcomes of TAVI in CKD hospitalization with different stages at the national cohort registry. We used the National Inpatient Sample database to compare TAVI CKD low-grade (LG) (stage I to IIIa, b) versus TAVI CKD high-grade (HG) (stage IV to V) in octogenarians. Outcomes such as inpatient mortality, cardiogenic shock, new permanent pacemaker implantation, acute kidney injury), sudden cardiac arrest, mechanical circulatory support, major bleeding, transfusion, and resource utilization were compared between the 2 cohorts. A total of 74,766 octogenarian patients (TAVI CKD-HG n = 12,220; TAVI CKD-LG n = 62,545) were included in our study. On matched analysis, TAVI CKD-HG had higher odds of in-hospital mortality (adjusted odds ratio [aOR] 2.18, 95% confidence interval [CI] 1.0-2.5, p <0.0001), cardiogenic shock (aOR 1.22, 95% CI 1.07 to 1.39, p = 0.0019), permanent pacemaker implantation (aOR 1.14, 95% CI 1.06 to 1.23, p = 0.0006), acute kidney injury (aOR 1.19, 95% CI 1.13 to 1.27, p <0.0001), sudden cardiac arrest (aOR 1.32, 95% CI 1.09 to 1.61, p = 0.004), major bleeding (aOR 1.1, 95% CI 1.006 to 1.22, p <0.0368) and higher rates of blood transfusion (aOR 1.62, 95% CI 1.5 to 1.75, p <0.0001) when compared with the TAVI CKD-LG cohort. However, there was no statistically significant difference in the odds of cerebrovascular accident and mechanical circulatory support use between the 2 groups.

RESUMEN

INTRODUCTION: This study aimed to investigate the association between social vulnerability, as measured by the Centers for Disease Control and Prevention's Social Vulnerability Index (SVI), and the quality of life (QoL) of kidney stone patients using the validated Wisconsin Stone Quality of Life Questionnaire (WISQOL). METHODS: A retrospective analysis was conducted on medical records of new urolithiasis patients who completed the WISQOL at the University of Rochester Medical Center kidney stone clinic. The primary outcome was WISQOL score, which was measured across multiple domains. SVI was used to assess social vulnerability. Neighborhoods with high SVI were defined by a threshold greater than or equal to the 75th percentile nationally. Demographic and clinical data were collected. Statistical analyses, including univariate tests and multivariate linear regression, were performed to evaluate the relationships between social vulnerability and disease-specific QoL. RESULTS: A total of 1718 patients were included in the study. One hundred five subjects (6.1%) were from neighborhoods of high social vulnerability. Patients residing in neighborhoods with high social vulnerability (SVI quartile) reported significantly lower QoL scores (69.1 vs 77.2; P = .001) and this persisted across all domains, including social impact (32.6 vs 35.1; P = .002), emotional impact (25.2 vs 27.5; P = .006), disease impact (28.5 vs 31.4; P = .001), and vitality (10.3 vs 11.2; P = .015). Younger age, female sex, and higher number of comorbidities were identified as independent predictors of lower QoL scores. However, non-White race and Latinx ethnicity did not exhibit a significant association with QoL scores. CONCLUSIONS: These findings highlight the negative impact of high social vulnerability on QoL, emphasizing the importance of considering socioeconomic factors in patient care. These results emphasize the need for targeted interventions to support vulnerable populations. While this study offers initial insights, further research is essential to corroborate these outcomes across larger and more diverse populations.

RESUMEN

Adult-acquired buried penis (AABP) is an acquired clinical entity where a normal sized phallus is concealed by prepubic skin, fat, or subcutaneous tissue, often caused by obesity, lymphedema, or trauma. Surgical repair is the standard of care in management of AABP; however, up to 60% of patients have developed bothersome genital lymphedema postoperatively. Despite the rates of postoperative scrotal lymphedema, and lymphedema itself representing a risk for AABP, very little data exist on the role of lymphatic evaluation in this patient population. We present the previously unreported use of indocyanine green (ICG) for lymphatic mapping as an adjunct to buried penis repair. Using 0.1 mL 25 mg per mL of indocyanine green and SPY Portable Handled Imaging, lymph mapping is performed, identifying lymph channels that seem obstructed as possible targets for lymphovenous bypass. In addition, lymph mapping can be used as an adjunct to surgical resection so as to not disrupt the intact channels, reducing the risk of postoperative lymphedema. Through this article, we offer emerging clinical insight into the possible use of lymphovenous bypass, particularly in patients with AABP due to lymphedema or those who experience lymphedema as a complication of AABP repair.

RESUMEN

INTRODUCTION: Nipple-sparing mastectomy (NSM) offers improved, patient-centered outcomes with demonstrated oncologic safety ( Ann Surg Oncol 2020;27:344-351). Indications for NSM continue to expand to patients outside of the traditional eligibility criteria, including those with prior breast-conserving therapy (BCT) with radiotherapy. Currently, limited data exist evaluating both short- and long-term outcomes in patients proceeding to NSM after prior BCT. METHODS: All patients undergoing bilateral NSM in a single institution from 2002 through 2017 with history of prior BCT were included in the final cohort, without exclusions. A retrospective chart review was performed to identify patient demographics, operative details, and complications. Outcomes assessed included early complications (<30 days from NSM), late complications (>30 days), rates of prosthetic failure, unplanned reoperations, and reconstructive failures, as well as oncologic safety. Student t , χ 2 , and Fisher exact tests were used to analyze outcomes of paired (BCT vs non-BCT) breasts within each patient. RESULTS: A total of 17 patients undergoing 34 NSMs were included. Each had a history of BCT and either ipsilateral breast recurrence (64.7%), risk-reducing NSM (23.5%), or a new contralateral primary cancer (11.8%). The cohort had a mean age of 51.1 years. With regard to acute complications (ischemia, infection, nipple-areolar complex or flap ischemia or necrosis, and wound dehiscence), there was no significant difference noted between breasts with prior BCT versus no prior BCT overall (41.2% vs 35.3%, respectively; P = 0.724). Complications occurring after 30 days postoperatively (capsular contracture, contour abnormality, animation deformity, bottoming out, rotation, and rippling) in prior BCT breasts versus no prior BCT had no significant differences overall (58.8% vs 41.2% respectively; P = 0.303). The mean follow-up was 5.5 years, during which no patients had a reported locoregional or distant recurrence in either breast. CONCLUSIONS: No significant differences in early or late complications were identified between breasts in patients undergoing bilateral NSM with a history of unilateral BCT and XRT. In the 5.5 years of follow-up, there were no recurrences, lending support to NSM for management of recurrent disease in addition to National Comprehensive Cancer Network-recommended total mastectomy. We propose that NSM should not be contraindicated in patients exposed to radiation with BCT.

RESUMEN

BACKGROUND: Textured implants were developed with the goal of reducing rates of capsular contracture and preventing implant malposition (eg., malrotation). Recent evidence has questioned whether textured implants are as resistant to malrotation as previously reported. METHODS: Women presenting to a single healthcare system for removal of textured implants were prospectively enrolled in the study from September 2019 to July of 2022. Patients who underwent removal of an anatomic, textured implant in the operating room were included in the study, while those who did not undergo implant removal, or were found to have a smooth implant, or a round, textured implant were excluded. The degree of implant rotation upon removal of the implant was measured intra-operatively. Implant specific factors, as well as patient demographics, clinical factors, and operative characteristics were collected. RESULTS: A total of 51 patients (80 implants) were included in the study. 45% of implants were malrotated (rotated >30 degrees) and the median degree of rotation was 30. Having more than one previous revision of the breast pocket was predictive of implant rotation (42 degrees) on multivariate linear regression analysis.
