RESUMO

OBJECTIVE: To estimate the annual percentage of patients with epithelial ovarian cancer (EOC) who could be eligible for and benefit from PARP inhibitor therapy amidst changing US Food and Drug Administration (FDA)-approved indications. METHODS: This is a simulated retrospective observational study using publicly available data on patients with advanced-stage EOC. PARPi eligibility is based on FDA approvals and withdrawals from 2014 through 2023, along with published demographic and genomic data. Clinical trial data is used to estimate treatment benefit. PARPi including olaparib, niraparib, and rucaparib are analyzed in aggregate with sub-analyses by molecular classification and treatment timing. Results are reported as the percentage of EOC patients appropriate for any cancer-directed therapy. RESULTS: PARPi were approved for 9 different indications in EOC between 2014 and 2021; reduced to 6 indications by 2023. Eligibility increased from 2.0% (95% CI,1.3%-1.6%) in 2014 to a maximum of 93.4% (95% CI,90.1%-94.6%) in 2021. The maximum percentage of patients with 2-year PFS benefit was 22.0% (95% CI, 17.2%-26.8%) in 2021, projected to decrease to 13.0% (95% CI, 9.9%-15.9%) in 2024. Most of this decrease was seen in the homologous recombination deficient, BRCA wild-type population (8.4% to 4.0%). CONCLUSIONS: PARPi eligibility increased at a greater rate than benefit resulting in a low population-level benefit-to-eligibility ratio until 2021. Recent FDA withdrawals improved this ratio with an accompanied decrease in the absolute number of patients benefiting. To further optimize population-level benefit-to-eligibility ratio of targeted therapies in ovarian cancer, we need to identify better biomarkers, treatment combinations, and novel therapeutic targets.

RESUMO

BACKGROUND: Patients may use crowdfunding to solicit donations, typically from multiple small donors using internet-based means, to offset the financial toxicity of cancer care. OBJECTIVE: To describe crowdfunding campaigns by gynecologic cancer patients and to compare campaign characteristics and needs expressed between patients with cervical, uterine, and ovarian cancer. STUDY DESIGN: We queried the public crowdfunding forum GoFundMe.com for "cervical cancer," "uterine cancer," and "ovarian cancer." The first 200 consecutive posts for each cancer type fundraising within the United States were analyzed. Data on campaign goals and needs expressed were manually extracted. Descriptive statistics and bivariate analyses were performed. RESULTS: Among the 600 fundraising pages, the median campaign goal was $10,000 [IQR $5000-$23,000]. Campaigns raised a median of 28.6% of their goal with only 8.7% of campaigns reaching their goal after a median of 54 days online. On average, ovarian cancer campaigns had higher monetary goals, more donors, and larger donation amounts than cervical cancer campaigns and raised more money than both cervical and uterine cancer campaigns. Campaigns were fundraising to support medical costs (80-85%) followed by lost wages (36-56%) or living expenses (27-41%). Cervical cancer campaigns reported need for non-medical costs more frequently than uterine or ovarian cancer campaigns. States without Medicaid expansions (31% of the national population) were over-represented among cervical cancer and uterine cancer, but not ovarian cancer campaigns. CONCLUSIONS: Crowdfunding pages reveal patients fundraising for out-of-pocket costs in the thousands of dollars and a wide range of unmet financial needs based on cancer type.

RESUMO

OBJECTIVE: To identify correlations between disease recurrence and adherence to NCCN posttreatment surveillance guidelines in patients who develop recurrent uterine cancer. METHODS: Retrospective analysis identified patients (n = 60) with recurrent uterine cancer and at least one surveillance visit with a gynecologic oncologist between 2011 and 2020. Adherence to NCCN guidelines and details of recurrence were recorded. RESULTS: Recurrent uterine cancer was identified in 60 patients with an average time to recurrence (TTR) of 25 months. Of those, 39 (65%) were adherent to NCCN surveillance guidelines and 36 (60%) were symptomatic at the time of recurrence diagnosis. Asymptomatic recurrence was diagnosed by imaging in 11 (46%), physical exam in 7 (29%), and blood work in 6 (25%) patients. Patients who were adherent to NCCN guidelines were diagnosed with recurrence on average 11 months earlier (p = 0.0336). Adherence was an independent predictor of TTR for all patients regardless of symptoms. There was no significant effect of age, race, primary language, or stage of disease on adherence. CONCLUSION: Adherence to NCCN posttreatment surveillance guidelines for uterine cancer is independently associated with an earlier diagnosis of recurrence.

RESUMO

Traditional horizontal osteotomies for small and short chins often yield suboptimal results due to limited bone advancement, resulting in deep labiomental folds and heightened bone resorption risks. This study investigates the effectiveness of an innovative inverted V-shaped osteotomy technique in enhancing esthetic outcomes for patients with such chin concerns. Thirty-eight patients who underwent inverted V-shaped osteotomy for recessed chins between January 2018 and June 2022 were included. Excluding cases involving simultaneous mandibular contouring surgery, patients were followed up for a median duration of 1.2±0.5 years. Preoperation and postoperation soft tissue pogonion (Pg') and labiomental fold depth (LMF) changes were measured. IBM SPSS (version 27.0) was used for statistical analysis, with significance defined as P <0.05. Patient satisfaction was assessed using a visual analog scale. Successful advancement genioplasty was performed on all patients without any severe complications. The average change in soft tissue pogonion (Pg') measured 6.2 (1.9) mm, and the mean alteration in labiomental depth was 0.42 (0.4) mm. The procedure achieved a bone to soft tissue movement ratio of 1:0.96. Patient satisfaction was notably high, with a mean VAS score of 8.7. An inverted V-shaped osteotomy enables greater bone advancement for small and short chins, leading to improved esthetic outcomes and offering a mechanically advantageous condition for bone segments.

RESUMO

OBJECTIVE: Alcohol-associated liver disease is accompanied by microbial dysbiosis, increased intestinal permeability and hepatic exposure to translocated microbial products that contribute to disease progression. A key strategy to generate immune protection against invading pathogens is the secretion of IgA in the gut. Intestinal IgA levels depend on the polymeric immunoglobulin receptor (pIgR), which transports IgA across the epithelial barrier into the intestinal lumen and hepatic canaliculi. Here, we aimed to address the function of pIgR during ethanol-induced liver disease. DESIGN: pIgR and IgA were assessed in livers from patients with alcohol-associated hepatitis and controls. Wild-type and pIgR-deficient (pIgR-/- ) littermates were subjected to the chronic-binge (NIAAA model) and Lieber-DeCarli feeding model for 8 weeks. Hepatic pIgR re-expression was established in pIgR-/- mice using adeno-associated virus serotype 8 (AAV8)-mediated pIgR expression in hepatocytes. RESULTS: Livers of patients with alcohol-associated hepatitis demonstrated an increased colocalisation of pIgR and IgA within canaliculi and apical poles of hepatocytes. pIgR-deficient mice developed increased liver injury, steatosis and inflammation after ethanol feeding compared with wild-type littermates. Furthermore, mice lacking pIgR demonstrated increased plasma lipopolysaccharide levels and more hepatic bacteria, indicating elevated bacterial translocation. Treatment with non-absorbable antibiotics prevented ethanol-induced liver disease in pIgR-/- mice. Injection of AAV8 expressing pIgR into pIgR-/- mice prior to ethanol feeding increased intestinal IgA levels and ameliorated ethanol-induced steatohepatitis compared with pIgR-/- mice injected with control-AAV8 by reducing bacterial translocation. CONCLUSION: Our results highlight that dysfunctional hepatic pIgR enhances alcohol-associated liver disease due to impaired antimicrobial defence by IgA in the gut.

RESUMO

Neonatal echovirus infections are characterized by severe hepatitis and neurological complications that can be fatal. Here, we show that expression of the human homologue of the neonatal Fc receptor (hFcRn), the primary receptor for echoviruses, and ablation of type I interferon (IFN) signaling are key host determinants involved in echovirus pathogenesis. We show that expression of hFcRn alone is insufficient to confer susceptibility to echovirus infections in mice. However, expression of hFcRn in mice deficient in type I interferon (IFN) signaling, hFcRn-IFNAR-/-, recapitulate the echovirus pathogenesis observed in humans. Luminex-based multianalyte profiling from E11 infected hFcRn-IFNAR-/- mice revealed a robust systemic immune response to infection, including the induction of type I IFNs. Furthermore, similar to the severe hepatitis observed in humans, E11 infection in hFcRn-IFNAR-/- mice caused profound liver damage. Our findings define the host factors involved in echovirus pathogenesis and establish in vivo models that recapitulate echovirus disease in humans.

RESUMO

OBJECTIVE: To determine whether Black race is associated with treatment and survival among women with low-risk endometrial cancer. METHODS: Black and White women with Stage IA grade 1-2 endometrioid endometrial carcinoma diagnosed from 2010 to 2016 in the SEER 18 dataset were identified (n = 23,431), and clinical and socioeconomic attributes obtained. Five-year cancer-specific survival (CSS) and relative survival (RS) were calculated using SEER*Stat 8.3.9. Cox proportional hazards model was used to determine predictors of overall survival (OS) and CSS. RESULTS: There was a significantly higher proportion of Black women who did not have surgery compared to White women (3% vs 1%, respectively; p < 0.0001). Residing in the South, being insured with Medicaid, and residing in a county with low median income were also associated with non-receipt of surgery. Black women remained less likely to undergo hysterectomy on multivariable analysis (OR 0.44, 95% CI 0.32-0.60). Non-receipt of hysterectomy was predictive of decreased CSS (HR 0.14, 95% CI 0.09-0.21) and OS (HR 0.18, 95% 0.14-0.23) on adjusted analysis. Black race was also an independent predictor of increased cancer-specific death (HR 2.07, 95% CI 1.50-2.86) as well as death from any cause (HR 1.74, 95% CI 1.44-2.09) on adjusted analysis. CONCLUSIONS: Black women with low-risk endometrial cancer were less likely to undergo hysterectomy and experienced decreased survival relative to White women. Further investigation is warranted to better understand the socioeconomic, geographic, and biologic factors that influence this disparity.

RESUMO

BACKGROUND: In our prior study, the authors determined that pulling on the superficial adipose layer is more effective in lifting the skin than pulling on the superficial musculoaponeurotic system (SMAS). Applying this concept of using the superficial adipose layer to transmit the lifting force to the skin, this study examined improvements in patients who underwent lateral midface lifting using our minimally invasive multilayer lifting technique and measured the duration of those improvements. METHODS: Along the hairline in front of the sideburns, a W-shaped zigzag incision of 3 to 8 mm in width and 3 to 4 cm in length was made. On the temporal scalp, 3 to 4 cm away from the first incision, a second incision was made more lateral/posterior to the first incision, and an elliptical excision of 3 to 5 mm in width and 3 to 4 cm in length was made. From the medial cut margin of the anterior first incision, the superficial temporal fascia/SMAS (the deep layer), and the superficial adipose layer (the superficial layer) were purchased with 3-0 polyester sutures, tunneled under the soft tissue, and fixed to the deep temporal fascia of the second posterior temporal incision. Prior to the excised temporal scalp closure, the dermis in the medial cut margin of the second incision was pulled to the rear as much as possible and fixed to the deep temporal fascia. RESULTS: The effects of surgery were monitored for 6 to 42 months after surgery. The nasolabial folds were improved. Skin elasticity also showed significant improvements, which lasted throughout the follow-up period (up to 42 mo). CONCLUSIONS: Unlike traditional wide dissection SMAS facelift, our method requires minimal incisions and does not require skin undermining. Therefore, the operating time is shorter, and postoperative swelling is minimized. In our technique, the superficial adipose layer, the superficial temporal fascia/SMAS, and the dermis were pulled individually to lift all layers of the lateral midface soft tissues. This results in a significant and long-lasting lateral midface rejuvenation.

RESUMO

Neonatal life marks the apogee of murine thymic growth. Over the first few days after birth, growth slows and the murine thymus switches from fetal to adult morphology and function; little is known about the cues driving this dramatic transition. In this study, we show for the first time (to our knowledge) the critical role of vascular endothelial growth factor (VEGF) on thymic morphogenesis beyond its well-known role in angiogenesis. During a brief window a few days after birth, VEGF inhibition induced rapid and profound remodeling of the endothelial, mesenchymal and epithelial thymic stromal compartments, mimicking changes seen during early adult maturation. Rapid transcriptional changes were seen in each compartment after VEGF inhibition, including genes involved in migration, chemotaxis, and cell adhesion as well as induction of a proinflammatory and proadipogenic signature in endothelium, pericytes, and mesenchyme. Thymocyte numbers fell subsequent to the stromal changes. Expression patterns and functional blockade of the receptors VEGFR2 and NRP1 demonstrated that VEGF mediates its pleiotropic effects through distinct receptors on each microenvironmental compartment of the developing mouse thymus.

RESUMO

INTRODUCTION: Despite improvement in progression-free survival with poly (ADP-ribose) polymerase inhibitors (PARPi) as maintenance therapy for ovarian cancer, many patients will eventually progress on therapy. Oligoprogression is uniquely suited to considerations of local consolidation therapy in this setting, but not commonly used in ovarian cancer. In this study we evaluated the proportion of patients on PARPi maintenance who developed limited sites of disease, the location of progression, and their natural history. METHODS: From January 2006 to December 2020, natural language processing software (DEEP6AI) was used to identify 58 patients with ovarian cancer treated with PARPi maintenance after complete or partial response after surgery and platinum-based chemotherapy at our institution. Patients were assessed for presence and location of recurrence based on radiologic findings. RESULTS: The median patient age was 65 (IQR 57-71) years. Patients had a median of two lines of chemotherapy prior to starting PARPi. With a median follow-up of 48 (range 12-149) months, 32 (55%) patients had a recurrence on maintenance olaparib and 11 (34%) patients developed oligoprogression (≤3 sites). For the 11 patients with oligoprogression, three patients developed recurrence in one site, five in two sites, and three in three sites. The sites of oligoprogression were pelvic/periaortic nodal (27%), peritoneal (27%), liver (27%), lung/mediastinal (14%), and brain (5%). The median progression-free survival for the entire cohort was 6.0 months (95% CI 4.2 to 7.8); median overall survival was not met. There were no significant differences in overall survival (p=0.81) or progression-free survival (p=0.95) between patients with and without oligoprogression. CONCLUSIONS: One-third of patients on PARPi maintenance experienced oligoprogression defined as limited to ≤3 sites. These patients may benefit from local consolidation therapy. A larger dataset is needed to validate these findings to assess if trials investigating local therapy for these patients is of value.

RESUMO

BACKGROUND: Influenza places a significant burden on global health and economics. Individual case management and public health efforts to mitigate the spread of influenza are both strongly impacted by our ability to accurately and efficiently detect influenza viruses in clinical samples. Therefore, it is important to understand the performance characteristics of available assays to detect influenza in a variety of settings. We provide the first report of relative performance between two products marketed to streamline detection of influenza virus in the context of a highly controlled volunteer influenza challenge study. METHODS: Nasopharyngeal swab samples were collected during a controlled A/California/2009/H1N1 influenza challenge study and analyzed for detection of virus shedding using a validated qRT-PCR (qPCR) assay, a sample-to-answer qRT-PCR device (BioMerieux BioFire FilmArray RP), and an immunoassay based rapid test kit (Quidel QuickVue Influenza A + B Test). RESULTS: Relative to qPCR, the sensitivity and specificity of the BioFire assay was 72.1% [63.7-79.5%, 95% confidence interval (CI)] and 93.5% (89.3-96.4%, 95% CI) respectively. For the QuickVue rapid test the sensitivity was 8.5% (4.8-13.7%, 95% CI) and specificity was 99.2% (95.6-100%, 95% CI). CONCLUSION: Relative to qPCR, the BioFire assay had superior performance compared to rapid test in the context of a controlled influenza challenge study.

RESUMO

OBJECTIVES: Poly(ADP-ribose) polymerase (PARP) inhibitors are expensive and their use is expanding. We aimed to evaluate cost sharing patterns between patients, payors, and financial assistance programs. METHODS: We identified ovarian cancer patients prescribed a PARP inhibitor from 5/2015-9/2019 using our pharmacy database. Cost information was collected for patients who filled their prescription at our specialty pharmacy. We calculated descriptive statistics for monthly PARP inhibitor costs for patients, payors, and financial assistance programs. We used Wilcoxon rank sum tests to evaluate monthly costs based on insurance characteristics. RESULTS: Seventy-six patients filled 94 different PARP inhibitor prescriptions with 42 (45%) prescriptions obtained using any type of financial assistance program. We analyzed 232 prescription months for the 41 prescriptions with available cost data. This included 18 (44%) prescriptions for rucaparib, 18 (44%) for niraparib, and 5 (12%) for olaparib. The total monthly drug cost was average $12,422 and median $13,700. The monthly out-of-pocket (OOP) cost for patients was average $46 and median $0 (IQR $0-4). Payors had the highest monthly costs with average $12,019 and median $13,662 (IQR $9914-14,709). Financial assistance programs contributed average $358 and median $0 per month (IQR $0-150). Patients with public (p<0.01) or Medicare insurance (p<0.01) had higher OOP costs than without. CONCLUSIONS: OOP costs were generally low with 75% of patients paying <$5 per month. While limited by small sample size at a single institution, financial assistance programs appear to play a critical role to ensure access to PARP inhibitors as nearly 50% of patients utilized these programs.

RESUMO

There is a strong rationale to consider future cell therapeutic approaches for cystic fibrosis (CF) in which autologous proximal airway basal stem cells, corrected for CFTR mutations, are transplanted into the patient's lungs. We assessed the possibility of editing the CFTR locus in these cells using zinc-finger nucleases and have pursued two approaches. The first, mutation-specific correction, is a footprint-free method replacing the CFTR mutation with corrected sequences. We have applied this approach for correction of ΔF508, demonstrating restoration of mature CFTR protein and function in air-liquid interface cultures established from bulk edited basal cells. The second is targeting integration of a partial CFTR cDNA within an intron of the endogenous CFTR gene, providing correction for all CFTR mutations downstream of the integration and exploiting the native CFTR promoter and chromatin architecture for physiologically relevant expression. Without selection, we observed highly efficient, site-specific targeted integration in basal cells carrying various CFTR mutations and demonstrated restored CFTR function at therapeutically relevant levels. Significantly, Omni-ATAC-seq analysis revealed minimal impact on the positions of open chromatin within the native CFTR locus. These results demonstrate efficient functional correction of CFTR and provide a platform for further ex vivo and in vivo editing.

RESUMO

STUDY OBJECTIVE: Determine near-optimal dose, safety, and efficacy of nerindocianine in pelvic ureter detection with near-infrared fluorescence imaging in women undergoing minimally invasive pelvic surgery with 3 Food and Drug Administration-cleared imaging systems. DESIGN: Open label, phase 1/2a study. SETTING: University of Alabama at Birmingham. PATIENTS: Forty-one female subjects undergoing minimally invasive gynecologic surgery. INTERVENTIONS: Subjects received a single dose of nerindocianine sodium, starting at 0.06-mg/kg body weight and increased/decreased until the near-optimal dose was determined (part A). Examine the degree of concordance between endoscopic and robotic devices (part B). MEASUREMENTS AND MAIN RESULTS: In part A, composite scores were collected every 10 minutes for 30 minutes and then every 15 minutes through 90 minutes using a scale measuring the anatomy/laterality of ureter visualization. In part B (paired imaging system efficacy), 2 cohorts of 8 subjects each received the near-optimal dose. Composite scores for visualization of the ureter were collected at 10 and 30 minutes postinfusion with the Firefly Imaging System and either the PINPOINT or 1588 AIM endoscope. Composite scores were compared to examine the degree of concordance between devices. Part A comprised 25 total subjects enrolled in dosing groups 1, 2, and 3 (0.06-, 0.12-, and 0.045-mg/kg, respectively). Median time to first ureter visualization was 10 minutes (all groups). The nerindocianine 0.06-mg/kg and 0.12-mg/kg groups had longer length of time of visualization than the 0.045-mg/kg group, resulting in the selection of 0.06 mg/kg as the near-optimal dose. Part B enrolled 16 total subjects in 2 groups dosed at 0.06 mg/kg. Efficacy analysis showed no statistically significant difference in composite scores with Firefly versus PINPOINT or 1588 AIM. CONCLUSION: Nerindocianine was well tolerated with visualization of the ureter demonstrated in 88.9% of the subjects through 90 minutes postdosing. No meaningful visualization differences were observed among the Food and Drug Administration-cleared surgical imaging systems used.

RESUMO

BACKGROUND: Cryopreserved human peripheral blood mononuclear cells (PBMCs) are a commonly used sample type for a variety of immunological assays. Many factors can affect the quality of PBMCs, and careful consideration and validation of an appropriate PBMC isolation and cryopreservation method is important for well-designed clinical studies. A major point of divergence in PBMC isolation protocols is the collection of blood, either directly into vacutainers pre-filled with density gradient medium or the use of conical tubes containing a porous barrier to separate the density gradient medium from blood. To address potential differences in sample outcome, we isolated, cryopreserved, and compared PBMCs using parallel protocols differing only in the use of one of two common tube types for isolation. METHODS: Whole blood was processed in parallel using both Cell Preparation Tubes™ (CPT, BD Biosciences) and Lymphoprep™ Tubes (Axis-Shield) and assessed for yield and viability prior to cryopreservation. After thawing, samples were further examined by flow cytometry for cell yield, cell viability, frequency of 10 cell subsets, and capacity for stimulation-dependent CD4+ and CD8+ T cell intracellular cytokine production. RESULTS: No significant differences in cell recovery, viability, frequency of immune cell subsets, or T cell functionality between PBMC samples isolated using CPT or Lymphoprep tubes were identified. CONCLUSION: CPT and Lymphoprep tubes are effective and comparable methods for PBMC isolation for immunological studies.

RESUMO

Studies of human T cell development require robust model systems that recapitulate the full span of thymopoiesis, from hematopoietic stem and progenitor cells (HSPCs) through to mature T cells. Existing in vitro models induce T cell commitment from human HSPCs; however, differentiation into mature CD3+TCR-αß+ single-positive CD8+ or CD4+ cells is limited. We describe here a serum-free, artificial thymic organoid (ATO) system that supports efficient and reproducible in vitro differentiation and positive selection of conventional human T cells from all sources of HSPCs. ATO-derived T cells exhibited mature naive phenotypes, a diverse T cell receptor (TCR) repertoire and TCR-dependent function. ATOs initiated with TCR-engineered HSPCs produced T cells with antigen-specific cytotoxicity and near-complete lack of endogenous TCR Vß expression, consistent with allelic exclusion of Vß-encoding loci. ATOs provide a robust tool for studying human T cell differentiation and for the future development of stem-cell-based engineered T cell therapies.

RESUMO

OBJECTIVES: Trainee well-being is a core component of ACGME program requirements and the SGO has recognized the high incidence of burnout among gynecologic oncologists and its negative impact. To foster a culture of wellness throughout the SGO community we sought to engage current fellows along with fellowship directors in a structured didactic program designed to teach wellness. We evaluated the feasibility of and preliminary responses to a pilot curriculum designed to teach skills that promote wellness and prevent burnout. METHODS: The SGO Wellness Taskforce developed a curriculum with topics based on established evidence as well as specialty specific stressors such as end of life discussions. Faculty leaders from 15 pilot-sites attended a full-day training course and then taught four modules over four months. Interactive modules engaged fellows through reflective writing, guided discussion, and multimedia presentations. Fellows completed the Perceived Stress Scale pre- and post-implementation and provided feedback regarding attitudes toward wellness and the individual modules. Faculty curriculum leaders completed surveys regarding their attitudes toward the curriculum as well as their trainees' reactions. RESULTS: Among 73 participating gynecologic oncology fellows, 95% (69/73) and 52/73 (71%) completed the pre-and post-surveys, respectively. Only 34/73 (49%) respondents reported that there was wellness programming at their institution prior to the initiation of the SGO curriculum. At institutions where such programming was available, 35% (12/34) reported not utilizing them. Fifty-five (80%) fellows had PSS scores greater than 12 compared to 39 (75%) post-intervention. After the curriculum, the percentage of fellows comfortable discussing wellness topics increased from 63 to 74%. Prior to the curriculum, 75% felt they could identify symptoms of burnout or psychosocial distress. This increased to 90% post-intervention. The modules were well received by fellows, and the time spent addressing wellness was widely appreciated. CONCLUSIONS: A structured curriculum to promote wellness among gynecologic oncology fellows is feasible and was associated with observed decreased reported stress among fellows at participating programs. This curriculum addresses ACGME requirements regarding trainee well-being, and showed potential for more programmatic, nationwide implementation. Fellowship culture change was not directly measured, but may have been one of the most significant positive outcomes of the wellness program. Further longitudinal studies will be necessary to understand the natural course of fellow burnout and the impact of structured wellness programming.

RESUMO

It has previously been shown that engineered zinc finger nucleases (ZFNs) can be packaged into adeno-associated viruses (AAVs) and delivered intravenously into mice, non-human primates, and most recently, humans to induce highly efficient therapeutic genome editing in the liver. Lipid nanoparticles (LNPs) are synthetic delivery vehicles that enable repeat administration and are not limited by the presence of preexisting neutralizing antibodies in patients. Here, we show that mRNA encoding ZFNs formulated into LNP can enable >90% knockout of gene expression in mice by targeting the TTR or PCSK9 gene, at mRNA doses 10-fold lower than has ever been reported. Additionally, co-delivering mRNA-LNP containing ZFNs targeted to intron 1 of the ALB locus with AAV packaged with a promoterless human IDS or FIX therapeutic transgene can result in high levels of targeted integration and subsequent therapeutically relevant levels of protein expression in mice. Finally, we show repeat administration of ZFN mRNA-LNP after a single AAV donor dose results in significantly increased levels of genome editing and transgene expression compared to a single dose. These results demonstrate LNP-mediated ZFN mRNA delivery can drive highly efficient levels of in vivo genome editing and can potentially offer a new treatment modality for a variety of diseases.

RESUMO

BACKGROUND: In order to correct upper lid laxity, upper blepharoplasty, subbrow excision, and forehead lift have been utilized. Our newly developed subbrow excision attaches the orbicularis oculi muscle to the frontalis muscle. This improves the longevity of the result without inhibiting the gliding plane of the periorbita. METHOD: From January 2016 to July 2018, 564 patients were operated on using this technique. Among them, 41 were male and 523 were female with the average age of 59.5 years. The average size of the subbrow excision was 55 mm × 8 mm. From the upper skin incision site, the upper dissection proceeded cephalad in the subcutaneous plane just above the orbicularis oculi muscle to the point where the frontalis muscle was seen. The lower flap was created by incising the orbicularis oculi muscle 5 mm cephalad to the distal skin incision. From this 5-mm orbicularis muscle stump, the dissection proceeded caudally in a plane between the orbicularis muscle and the orbital septum. Once this flap was created, the 5-mm muscle stump was attached to the exposed frontalis muscle in a horizontal mattress fashion in three areas. The skin incision was then closed. Three months after the operation, a satisfaction survey was conducted using the Likert scale. RESULTS: The patients were followed postoperatively for at least 6 months. In all but two cases, the orbital laxity improved. However, in the brow's lateral third where the frontalis muscle does not exist, a slight lowering of the brow had occurred. The incision healed well without any keloid or hypertrophic scars. There were no significant complications such as superior orbital nerve entrapment-related sensory problems. CONCLUSIONS: Subbrow lift utilizing the frontalis muscle attachment to the lower flap orbicularis muscle is a novel method of correcting upper eyelid skin hooding. The technique does not rely on periosteal fixation. Therefore, the eyebrow gliding plane is not violated. Thus, the natural eyebrow movement is maintained. There were no cases of injury to the deep branch of the supraorbital nerve, poor wound healing, or other significant complications.

RESUMO

OBJECTIVE: To compare the perioperative morbidity and survival between abdominal radical hysterectomy (ARH) and robotic radical hysterectomy (RRH). METHODS: A retrospective cohort of patients undergoing radical hysterectomy for cervical cancer from 2010 to 2016 was identified. Patients with stage IB1 cervical cancer were included and were grouped by ARH vs. RRH. Tumor characteristics, perioperative complications, recurrence rate, progression-free survival (PFS), and overall survival (OS) were compared between groups. RESULTS: 105 patients were identified; 56 underwent ARH and 49 underwent RRH. Those who had ARH were more likely to have lesions that were ≥2 cm (62% vs. 39%, p = 0.02) and that were higher grade (p = 0.048). Other tumor characteristics were similar between groups. There was no difference in perioperative complication rates between groups. Additionally, there were no differences in recurrence risk (RR) (14% vs. 24%, p = 0.22), progression-free survival (PFS) (p = 0.28), or overall survival (OS) (p = 0.16). However, in those with tumors ≥2 cm there was a higher risk of recurrence in the overall cohort (30% vs. 8%, p = 0.006), and a shorter PFS in the RRH group (HR 0.31, p = 0.04). On multivariate analysis patients that underwent ARH or had tumors < 2 cm had a lower likelihood of recurrence (HR 0.38, p = 0.04; HR 0.175, p = 0.002) and death (HR 0.21, p = 0.029; HR 0.15, p = 0.02). CONCLUSION: Perioperative morbidity was similar between those undergoing ARH vs. RRH for IB1 cervical cancer. Patients with tumors ≥ 2 cm undergoing RRH had a shorter PFS compared to ARH. On multivariate analysis, RRH and tumor size ≥ 2 cm were independently associated with recurrence and death in this population.
