Proliferation Patterns of MCF-7 Breast Cancer Cells in Lipoaspirate Conditioned Media.

INTRODUCTION: Autologous fat grafting (AFG) is a common technique used to enhance aesthetic outcomes in postmastectomy breast reconstruction patients. Adipokines are hormones secreted by adipose tissue that play a critical role in regulating metabolic processes and the immune system. However, dysregulated adipokine secretion and signaling can contribute to the development and progression of cancer by promoting angiogenesis, altering the immune response, and inducing the epithelial mesenchymal transition. We aimed to assess how breast cancer cells behave in conditioned media derived from fat grafting lipoaspirates and gain a better understanding of the potential interactions that may occur within the tumor microenvironment. METHODS: Patients who were undergoing AFG as a part of breast reconstruction at NY-Presbyterian/Weill Cornell Medical Center between March 2021 and July 2023 were consented and enrolled in the study. This study was approved by the Weill Cornell Medicine Institutional Review Board (#20-10022850-14). Conditioned media is created using 20% of patient lipoaspirate secretome and 80% starving media. The growth of MCF-7, a human ER/PR+ breast cancer cell line, in conditioned media is assessed using CyQUANT. RESULTS: The breast cancer cells incubated in conditioned media displayed similar growth trends as those in complete media, which is enriched for cell growth (P > 0.05). MCF-7 cell behavior in conditioned media differed significantly from their proliferation patterns when serum starved in 100% starving media (P < 0.05). DISCUSSION: Our results suggest that there may be inherent factors within the lipoaspirate that may promote MCF-7 proliferation. One potential implication is that AFG used for breast reconstruction should be delayed until local-regional disease control has been established. In addition, based on the in vitro proliferation patterns of breast cancer cells in conditioned media, the safety profile of AFG may be enhanced if the procedure is performed after attaining negative margins and the completion breast cancer treatment.

Assessing Long-Term Volume Retention in Breast Fat Grafting: A Comparative Study of Lipoaspirate Processing Techniques.

INTRODUCTION: Autologous fat grafting is a method of improving aesthetic outcomes after both breast reconstruction and aesthetic surgery through volume enhancement and tissue contouring. Long-lasting effects are linked to greater patient satisfaction and more optimal augmentation results. Harvesting, processing, and injection techniques may all affect the longevity of deformity filling. Our objective is to evaluate the effect of lipoaspirate processing modality on longitudinal volume retention after surgery. METHODS: A prospective, single-institution, randomized control trial placed consented postmastectomy fat grafting patients into 1 of 3 treatment arms (active filtration, low-pressure decantation, and standard decantation) in a 1:1:1 ratio. A preoperative 3-dimensional scan of the upper torso was taken as baseline. At the 3-month postoperative visit, another 3D scan was taken. Audodesk Meshmixer was used to evaluate the volume change. RESULTS: The volume of fat injected during the initial procedure did not differ significantly between the treatment arms (P > 0.05). Both active filtration and low-pressure decantation resulted in higher percentage volume retention than traditional decantation (P < 0.05). Active filtration and low-pressure decantation exhibited comparable degrees of fat maintenance at 3 months (P > 0.05). DISCUSSION: Compared with using traditional decantation as the lipoaspirate purification technique, active filtration and low-pressure decantation may have led to higher levels of cell viability by way of reduced cellular debris and other inflammatory components that may contribute to tissue resorption and necrosis. Further immunohistochemistry studies are needed to examine whether active filtration and low-pressure decantation lead to lipoaspirates with more concentrated viable adipocytes, progenitor cells, and factors for angiogenesis.

Cleft Lip and Palate Surgery at a Rural African Hospital: A 13-Year Experience From Western Kenya.

INTRODUCTION: Most studies on the treatment of cleft lip and palate (CLP) in low-income and middle-income countries have reported on the experience of urban centers or surgical mission trips to rural locations. There is a paucity of literature on the experience of local teams providing orofacial cleft surgery in rural Sub-Saharan Africa. This study reports the efficacy and cost-effectiveness of cleft surgery performed by an all-local team in rural Kenya. METHODS: A retrospective chart review was performed on all patients who received CLP repair at Kapsowar Hospital between 2011 and 2023. Information regarding patient age, sex, cleft etiology, surgical management, and home location was retrieved. For the most recent year of study (2023), the authors performed a financial audit of all costs related to the performance of unilateral cleft lip surgery. Descriptive statistics were performed. RESULTS: The authors identified 381 CLP surgeries performed on 311 patients (197 male, 63.3%). The most common etiology of the cleft was left unilateral (28.3%). The average age of primary lip repair decreased from 46.3 months in 2008 to 2009 to 20.2 months in 2022 to 2023 (P<0.001). The average age of primary cleft palate repair decreased from 38.0 months in 2008 to 2009 to 25.3 months in 2022 to 2023 (P<0.001). Patients traveled from 23 districts to receive treatment. Age of treatment was not different when distinguished by sex, county poverty level, or travel time from the hospital. The total costs associated with cleft lip repair was $201.6. CONCLUSIONS: Adequately staffed hospitals in rural locations can meaningfully address a regional CLP backlog more cost-effectively than surgical mission trips.

The Pattern and Profile of Orofacial Clefts in Somaliland: A Review of 40 Consecutive Cleft Lip and Palate Surgical Camps.

INTRODUCTION: Somaliland is an autonomously run country that is not internationally recognized. As such, it has been largely excluded by global health development programs despite being the world's fourth poorest country. The purpose of this study was to provide the first known description of the pattern and clinical profile of patients with cleft lip and palate from this nation. METHODS: The authors performed a retrospective chart review on all patients who received cleft lip and palate repair by a single surgeon in 40 separate surgical camps at Edna Adan University Hospital in Hargeisa, Somaliland, between 2011 and 2024. Information regarding patient age, sex, cleft etiology, surgical management, and home location was retrieved. Descriptive statistical analysis was performed. RESULTS: A total of 767 patients (495 male, 64.5%) received 787 surgical procedures. The average age of primary surgery was 73.7 months. The most common chief complaint was left cleft lip with cleft palate (316, 41.2%). Males received primary surgery 19.2 months later than did females (73.7 and 54.6 mo, respectively, P<0.001). Patients residing in Hargeisa received their initial procedure an average of 17.8 months younger than those who lived elsewhere in Somaliland (62.9 and 80.7 mo, respectively, P=0.004). CONCLUSIONS: In this severely economically depressed region, patients received treatment at ages that lagged far beyond recommended guidelines. Our finding of earlier treatment for females than males is rare in the literature and likely relates to cultural sex expectations. Patients from rural locations were especially vulnerable to receiving delayed treatment. Further efforts to decrease the burden of craniofacial deformities in Somaliland should be pursued in earnest.

Assessment of diversity in skin colour in dermatology medical education resources.

One hundred and fifty-three patient images from the general resources and 3583 images from Dermatology were evaluated. The majority of images were Fitzpatrick Type II (54%), followed by Type III (27%). Our findings demonstrate the lack of skin diversity continues across many medical school resources, with fair skin (Fitzpatrick Type II) accounting for the majority of images.

Clinical Characteristics and Surgical Outcomes of 2542 Patients with Spinal Schwannomas: A Systematic Review and Meta-Analysis.

OBJECTIVE: This study was conducted to systematically analyze the data on the clinical features, surgical treatment, and outcomes of spinal schwannomas. METHODS: We conducted a systematic review and meta-analysis under the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of bibliographic databases from January 1, 2001, to May 31, 2021, yielded 4489 studies. Twenty-six articles were included in our final qualitative systematic review and quantitative meta-analysis. RESULTS: Analysis of 2542 adult patients' data from 26 included studies showed that 53.5% were male, and the mean age ranged from 35.8 to 57.1 years. The most common tumor location was the cervical spine (34.2%), followed by the thoracic spine (26.2%) and the lumbar spine (18.5%). Symptom severity was the most common indicator for surgical treatment, with the most common symptoms being segmental back pain, sensory/motor deficits, and urinary dysfunction. Among all patients analyzed, 93.8% were treated with gross total resection, which was associated with better prognosis and less chance of recurrence than subtotal resection. The posterior approach was the most common (87.4% of patients). The average operative time was 4.53 hours (95% confidence interval [CI], 3.18-6.48); the average intraoperative blood loss was 451.88 mL (95% CI, 169.60-1203.95). The pooled follow-up duration was 40.6 months (95% CI, 31.04-53.07). The schwannoma recurrence rate was 5.3%. Complications were particularly low and included cerebrospinal fluid leakage, wound infection, and the sensory-motor deficits. Most of the patients experienced complete recovery or significant improvement of preoperative neurological deficits and pain symptoms. CONCLUSIONS: Our analysis suggests that segmental back pain, sensory/motor deficits, and urinary dysfunction are the most common symptoms of spinal schwannomas. Surgical resection is the treatment of choice with overall good reported outcomes and particularly low complication rates. gross total resection offers the best prognosis with the slightest chance of tumor recurrence and minimal risk of complications.

Association of baseline frailty and age with postoperative outcomes in metastatic brain tumor patients.

BACKGROUND: The impact of baseline frailty status versus that of chronological age on surgical outcomes of metastatic brain tumor patients remains largely unknown. The present study aimed to evaluate this relationship for preoperative risk stratification using a large national database. METHODS: The National Surgical Quality Improvement Program database was queried to extract data of metastatic brain tumor patients who underwent surgery between 2015 and 2019 (n=5,943). Univariate and multivariate analyses were performed to assess the effect of age and modified frailty index-5 (mFI-5) on mortality, major complications, unplanned readmission and reoperation, extended length of stay (eLOS), and non-home discharge. RESULTS: Both univariate and multivariate analyses demonstrated that frailty status was significantly predictive of 30-day mortality, major complications, eLOS, and non-home discharge. Although increasing age was also a significant predictor of eLOS and discharge to non-home destination, effect sizes were smaller compared with frailty. CONCLUSIONS: The present study, based on analysis of data from a large national registry, shows that frailty, when compared with age, is a superior predictor of postoperative outcomes in metastatic brain tumor patients. A future prospective study, namely a randomized controlled trial, would be beneficial in helping to corroborate the findings of this retrospective study.

Multinodular and Vacuolating Neuronal Tumor: Incidental Diagnosis of a Rare Brain Lesion.

Multinodular and vacuolating neuronal tumor (MVNT) is a rare benign brain lesion, commonly found in middle-aged adults. The patients experience a range of symptoms from being asymptomatic to epileptic seizures, with headache being the most common symptom. Here we report a case of an incidental diagnosis of MVNT in a young female. A 25-year-old female with a past medical history of occasional headaches without seizures or any focal neurological deficit presented after a motor vehicle rollover. The MRI brain revealed an incidental finding of a subcortical lesion in the right parietal lobe with T2-FLAIR (fluid-attenuated inversion recovery) hyperintensity between the cystic portions, indicative of a possible MVNT, with a less probable chance of dysembryoplastic neuroepithelial tumor based on the subcortical location of the lesion. No neurosurgical intervention was recommended. With one-year follow-up, no changes were noted on neuroimaging, and the patient remained stable without any neurological symptoms. The MVNT is a rare brain lesion that presents with benign features. In patients with epileptic symptoms, surgical resection of the lesion can be curative. However, in asymptomatic patients, careful monitoring may be sufficient, as described in this case.
