One of the earliest reported cases of autologous fat grafting (AFG) was by Neuber in 1893 and consisted of the transfer of small lobules of fat from the upper arm for cicatrical depression of the face. He advocated the use of smaller grafts, noting that pieces larger than the size of a bean would form cysts. In 1895, Czerny excised a lumbar lipoma and transplanted it to the chest for breast reconstruction. Since these early reports, the knowledge base around AFG has expanded exponentially, as illustrated by the other papers within this special topic. As we embark on the next phase of AFG in the clinical setting, there are several directions which are near-clinical translation. This paper discusses future directions in fat grafting that build on optimization of our current techniques as clinical indications expand, such as supplementing purified lipoaspirate and the associated regulatory burden, or deconstructing adipose tissue to selectively use adipose graft components for a variety of regenerative indications.Autologous fat grafting for buttock augmentation is one of the fastest growing plastic surgery procedures, but has also received significant publicity for the relatively high mortality rate secondary to fat emboli. The literature has grown exponentially in the past 5 years on this subject, helping to clarify our knowledge and providing recommendations to minimize risks, including avoiding intramuscular injections, placing the patient in the jackknife position, and utilizing larger-bore cannulas. Since the application of these recommendations, the rate of pulmonary fat embolism has decreased from 0.097% to 0.04%, with a current mortality of 1 in 14,921, making it statistically safer than abdominoplasty. Despite the evolution in our knowledge, techniques, and outcomes, it remains of utmost importance to properly select and educate patients about the safety of fat grafting for buttock augmentation. Level of Evidence 4.Autologous fat grafting is an important tool in plastic surgery and is widely used for a variety of applications, both aesthetic and reconstructive. Despite an ever-increasing list of indications and extensive research over many years into improving outcomes, fat grafting remains plagued by incomplete and often unpredictable graft survival. Decisions made at each stage of surgery can potentially contribute to ultimate success, including donor site selection and preparation, fat harvest, processing, and purification of lipoaspirate, recipient site preparation, and delivery of harvested fat to the recipient site. In this review, we examine the evidence for and against proposed techniques at each stage of fat grafting. Areas of consensus identified include use of larger harvesting and grafting cannulas and slow injection speeds to limit cell damage due to shearing forces, grafting techniques emphasizing dispersion of fat throughout the tissue with avoidance of graft pooling, and minimizing exposure of the lipoaspirate to the environment during processing. Safety considerations include use of blunt-tipped needles or cannulas to avoid inadvertent intravascular injection as well as awareness of cannula position and avoidance of danger zones such as the subgluteal venous plexus. We believe that using the evidence to guide surgical decision-making is the key to maximizing fat grafting success. Level of Evidence 4.Autologous fat grafting (AFG) serves as an effective method to address volume defects, contour irregularities, and asymmetry in both aesthetic and reconstructive procedures. In recent years, there has been growing concern about the potential of cancer recurrence and interference with cancer surveillance in oncologic patients receiving AFG. The adipose tissue contains adipose-derived stem cells (ASCs), a specific type of mesenchymal stem cells, that facilitate secretion of numerous growth factors which in turn stimulate tissue regeneration and angiogenesis. As such, it has been theorized that ASCs may also have the potential to stimulate cancer cell proliferation and growth when used in oncologic patients. Multiple research studies have demonstrated the ability of ACSs to facilitate tumor proliferation in animal models. However, clinical research in oncologic patients has yielded contradictory findings. Although the literature pertaining to oncologic safety in head and neck, as well as sarcoma, cancer patients remains limited, studies demonstrate no increased risk of tumor recurrence in these patient populations receiving AFG. Similarly, both the efficacy and safety of AFG have been well established in breast cancer patients through numerous clinical studies. More recently, preclinical research in animal models has shown that AFG has the potential to facilitate tissue regeneration and improve joint contracture following irradiation. Ultimately, further research is needed to elucidate the safety of AFG in a variety of oncologic patients, as well as explore its use in tissue regeneration, particularly in the setting of radiotherapy. Level of Evidence 4.Prior to 2017, heroin and other prescription opioids were the most prevalent opioids implicated in driving under the influence of drugs (DUID) investigation cases and fentanyl was rarely included in the scope of toxicological analysis. Fentanyl has become the most frequently identified opioid in DUID cases with many suspected heroin cases turning out to be only fentanyl. A review of fentanyl positive DUID cases at NMS Labs was performed to provide prevalence information, change in concentration, patterns of combined drug use, indicators of impairment, and driving behavior in order to assist with toxicological interpretation of DUID scenarios involving fentanyl. Fentanyl positive DUID cases received between January 2010 and December 2020 were examined. Blood results were confirmed and quantitated for fentanyl, norfentanyl and acetylfentanyl using a liquid chromatography-tandem mass spectrometry (LC-MS-MS) analysis with a limit of quantitation (LOQ) of 0.10, 0.20 and 0.10 ng/mL, respectively. Lanifibranor clinical trial Of 153,234 blood cases examined for DUID over 11 years, fentanyl confirmed positive in 6,779 (4.4%) cases. However, there were significant changes in positivity over time. Fentanyl percent positivity increased from 0.60% in 2010 to 12% in 2020. Of 5,976 confirmed fentanyl positive cases in 2018 through 2020, blood concentrations greater than 4.0 ng/mL were observed in 44% (2018), 55% (2019), and 59% (2020) of cases. Polypharmacy was common with 87% of blood samples confirming positive for fentanyl and at least one other compound. Stimulants was the most commonly identified drug class in cases where at least one additional drug class was present. This study illustrates the importance of including fentanyl in a routine blood DUID panel.
