    Abstract Background: Nipple-sparing mastectomy is associated with greater patient satisfaction than non-nipple-sparing approaches. Although various nipple-sparing mastectomy incisions have been described, the authors hypothesized that incision location would impact the rate and location of ischemic complications to the mastectomy skin flap.
    Methods: A prospectively maintained database was queried to identify patients who underwent nipple-sparing mastectomy with immediate microsurgical reconstruction with a minimum postoperative follow-up of 12 months. The impact of incision location on postoperative ischemic complications was investigated. Major complications were defined as those that required reexploration in the operating room or inpatient management; minor complications were amenable to outpatient management. Multivariable logistic and linear regression were performed to investigate risk factors for postoperative complications following breast reconstruction.
    Results: Eighty-seven patients met inclusion criteria. The following nipple-sparing mastectomy incisions were used: radial with a periareolar extension (39 percent), inframammary fold (31 percent), vertical with a periareolar extension (22 percent), vertical (6 percent), and radial (2 percent). Seven patients (8 percent) had major complications, whereas twenty-six patients (29.9 percent) developed minor postoperative complications. Inframammary fold incisions were associated with significantly greater rates of mastectomy skin flap necrosis (p = 0.002), whereas periareolar incisions were associated with significantly greater rates of postoperative nipple-areola complex necrosis (p = 0.04).
    Conclusions: The authors report a significant association between incision location and ischemic complications to the breast skin envelope in microsurgical breast reconstruction. The authors observed a significant association of inframammary fold and periareolar incisions with mastectomy skin flap and nipple-areola complex necrosis, respectively.

    Abstract Radiation-induced breast angiosarcoma, or secondary angiosarcoma (SAS), is a rare entity with a high risk of metastatic recurrence. Herein, we describe the use of intraoperative fluorescence-based skin angiography to guide surgical resection following a novel immunotherapy-based regimen for SAS resulting in a complete pathological response.

    Abstract Staged expander-based breast reconstruction represents the most common reconstructive modality in the United States. The introduction of a novel tissue expander with an integrated drain (Sientra AlloX2) holds promise to further improve clinical outcomes.
    Methods: Patients who underwent immediate expander-based pre-pectoral breast reconstruction were identified. Two cohorts were created, that is, patients who underwent placement of a conventional tissue expander [133MX (Allergan)] (Group 1) versus AlloX2 (Sientra) (Group 2). The study endpoint was successful completion of expansion with the objective being to investigate differences in outcome following expander placement.
    Results: Fifty-eight patients underwent 99 breast reconstructions [Group 1: N = 24 (40 breasts) versus Group 2: N = 34 (59 breast)]. No differences were noted for age (
    Conclusion: The unique feature of the AlloX2 provides surgeons easy access to the peri-prosthetic space without altering any of the other characteristics of a tissue expander. This resulted in a reduced time to drain removal and facilitated management of postoperative seroma and infection.

    Abstract While surgical options exist to treat lymphedema after axillary lymph node dissection (ALND), the lymphatic microsurgical preventive healing approach (LYMPHA) has been introduced as a preventive measure performed during the primary surgery, thus avoiding the morbidity associated with lymphedema. Here, we highlight details of our operative technique and review postoperative outcomes. For our patients, limb measurements and body composition analyses were performed pre- and postoperatively. Intraoperatively, axillary reverse lymphatic mapping was performed with indocyanine green (ICG) and lymphazurin. SPY-PHI imaging was used to visualize the ICG uptake into axillary lymphatics. Cut lymphatics from excised nodes were preserved for lymphaticovenous anastomosis (LVA). At the completion of the microanastomosis, ICG was visualized draining from the lymphatic through the recipient vein. A retrospective review identified nineteen patients who underwent complete or partial mastectomy with ALND and subsequent LYMPHA over 19 months. The number of LVAs performed per patient ranged between 1–4 per axilla. The operating time ranged from 32–95 min. There were no surgical complications, and thus far one patient developed mild lymphedema with an average follow up of 10 months. At the clinic follow up, ICG and SPY angiography were used to confirm intact lymphatic conduits with an uptake of ICG across the axilla. This study supports LYMPHA as a feasible and effective method for lymphedema prevention.

    Abstract Purpose: Window of opportunity trials (WOT) are increasingly common in oncology research. In WOT participants receive a drug between diagnosis and anti-cancer treatment, usually for the purpose of investigating that drugs effect on cancer biology. This qualitative study aimed to understand patient perspectives on WOT.
    Methods: We recruited adults diagnosed with early-stage breast cancer awaiting definitive therapy at a single-academic medical center to participate in semi-structured interviews. Thematic and content analyses were performed to identify attitudes and factors that would influence decisions about WOT participation.
    Results: We interviewed 25 women diagnosed with early-stage breast cancer. The most common positive attitudes toward trial participation were a desire to contribute to research and a hope for personal benefit, while the most common concerns were the potential for side effects and how they might impact fitness for planned treatment. Participants indicated family would be an important normative factor in decision-making and, during the COVID-19 pandemic, deemed the absence of family members during clinic visits a barrier to enrollment. Factors that could hinder participation included delay in standard treatment and the requirement for additional visits or procedures. Ultimately, most interviewees stated they would participate in a WOT if offered (N = 17/25).
    Conclusion: In this qualitative study, interviewees weighed altruism and hypothetical personal benefit against the possibility of side effect from a WOT. In-person family presence during trial discussion, challenging during COVID-19, was important for many. Our results may inform trial design and communication approaches in future window of opportunity efforts.

    Abstract Recent clinical and experimental findings have reinforced the link among zinc deficiency, malnutrition and diarrheal disease. Because there is a strong association between protein and zinc content in virtually all types of foods, insufficient protein intake may often be the cause of zinc deficiency. Compensatory mechanisms operating in monogastric species during malnutrition are less effective for the absorption of transition divalent elements such as zinc, which remain bound to ligands of dietary or endogenous origin. Both protein and zinc deficiencies are strong negative determinants for normal cellular immunity. In zinc deficiency, the organism is more susceptible to toxin-producing bacteria or enteroviral pathogens that activate guanylate and adenylate cyclases, stimulating chloride secretion, producing diarrhea and diminishing absorption of nutrients, thus exacerbating an already compromised mineral status. In addition, zinc deficiency may impair the absorption of water and electrolytes, delaying the termination of normally self-limiting gastrointestinal disease episodes. The gastrointestinal tract may be one of the first target areas where zinc insufficiency may be manifested. A prolonged low zinc intake deprives the organism of the local potential beneficial effects of zinc, including interactions with oxidative free radicals and nitric oxide metabolism. Nitric oxide is a second messenger that plays an important part in the triggering of diarrheal disease. The possible interrelationship among infection, inflammation, free radical damage and its quenching by potential scavengers, such as zinc, in the intestinal lumen or within the enterocyte should be more extensively studied.

    Abstract The human gastrointestinal system can absorb 30-40% of ingested copper from the typical diets consumed in industrialized countries. Experimental data support the existence of a carrier-mediated transport mechanism with an affinity constant in the micromolar range. Aging probably decreases the efficiency of copper homeostasis, resulting in higher plasma copper concentrations in the elderly. Physiologic differences may account for the higher cupremia of females. Supplements of minerals with similar chemical characteristics could reduce copper absorption. This property has pharmacologic applications in Wilson disease. Manipulation of the fiber content of the diet may have an indirect effect on copper bioavailability by altering the bioavailability of mineral antagonists. Proteins and soluble carbohydrates tend to improve copper absorption and bioavailability by enhancing its solubility and intestinal bulk flow. Organic acids, other than ascorbic acid, or agents that form low-molecular-weight chelates, are likely to have a positive effect on overall copper absorption. Conditions associated with malabsorption of macronutrients and gastrointestinal disease can impair copper uptake and contribute to suboptimal copper status.
