RESUMO

IMPORTANCE: There are no current data investigating the relationship between mesh-exposure complications after midurethral sling surgery and antiestrogen therapy. OBJECTIVES: We sought to determine if there are increased mesh-exposure complications between a breast cancer population versus a noncancer population particularly in conjunction with hormone suppression (HS) therapy. STUDY DESIGN: A retrospective chart review was performed on patients with a history of breast cancer undergoing tension-free vaginal tape (TVT) surgery at our institution between 2013 and 2021. A group of patients who underwent TVT surgery without a history of cancer served as our control. Univariate and multivariate logistic regression analyses were performed to identify predictors of mesh exposure complications. RESULTS: One hundred twenty-one patients with breast cancer had TVT surgery. Two hundred ninety-seven patients without cancer had TVT surgery during the same period. Baseline characteristics across all groups were similar. Twenty-nine patients (6.9%) experienced mesh exposure. This occurred at a higher rate in our cancer (15.7%) versus the noncancer population (3.4%). Women with breast cancer taking HS therapy had a higher rate of mesh exposure complications compared with those not taking HS therapy (25.0% versus 6.6%; P = 0.005). The highest rate of mesh exposure complications occurred in the cohort taking estrogen receptor modulators, selective estrogen receptor modulator (10/36 [27.8%]) versus aromatase inhibitors (5/24 [20.8%]) versus no HS therapy (4/61 [6.6%]; P = 0.014). On multivariate analysis, HS therapy use (odds ratio, 1.57; P = 0.007) and diabetes mellitus (odds ratio, 4.53; P = 0.018) were associated with increased TVT-related complications. CONCLUSION: Women with breast cancer had a higher rate of mesh exposure complications from TVT surgery compared with women without cancer, particularly those taking antiestrogenic therapy.

RESUMO

BACKGROUND: Interstitial mycosis fungoides (IMF) is a rare subtype of mycosis fungoides (MF) characterized by atypical lymphocytes infiltrating the reticular dermis between collagen bundles with limited epidermotropism and variable granulomatous features. METHODS: Retrospective single institution review of 31 cases of IMF including clinical characteristics, disease course and pathological features. RESULTS: Our cohort was predominately male (19; 61%, M:F 1.6:1) with a mean age at diagnosis of 43 years (range 11-85), mean signs/symptoms duration of 7 years prior to diagnosis, and 6 years mean follow-up duration. Clinically, patients often exhibited symmetric ill-defined patches/plaques involving intertriginous regions with tan-yellow hyperpigmentation and follicular-based papules, wrinkling, and alopecia. Lymphadenopathy was noted in seven patients. Fifteen (52%) patients were in near or complete clinical remission at the latest follow-up. T-cell receptor gene rearrangement was positive in 23/24 (96%) cases. Histopathologically, atypical cells were small-medium, CD4+ (29; 94%) or rarely CD4+/CD8+ (1; 3%) lymphocytes infiltrating the reticular dermis with thickened collagen bundles (27; 87%), multinucleated giant cells (12; 39%), and often tracing along adnexa with subtle folliculotropism (12/20; 60%). CONCLUSIONS: Our study demonstrates IMF is an indolent subtype of MF with distinct features, including frequent granulomatous and subtle follicular involvement resulting in alopecia.

RESUMO

ABSTRACT: Epstein-Barr virus (EBV)-positive lymphoproliferative disorders associated with immunodeficiency constitute a spectrum of lymphoid and plasma cell proliferations that vary in cytomorphology, immunophenotype, and clinical behavior. CD30-positive cutaneous lymphocytic infiltrates with EBV expression and lymphomatoid papulosis-like presentations have been rarely reported. This retrospective study assessed the clinical and histopathological characteristics of EBV-positive cases with papulonodular morphologies and CD30 positivity seen by Northwestern Medicine Dermatopathology. Twelve patients (7M:5F, mean age 69 years) were presented with papular cutaneous lesions without antecedent patch/plaque disease. Nine cases were associated with known immunosuppression in the setting of transplant-related therapies (n = 4), hematopoietic malignancy (n = 2), post-transplant hematopoietic malignancy (n = 1), and autoimmune disease treatment (n = 2). Two patients had age-related immunosenescence. Four patients demonstrated EBV viremia; for 2 patients, this finding comprised the first sign of immunosuppression. Workup was negative for systemic lymphoma in all patients. Various treatment strategies were used, including observation (n = 3), discontinuation/reduction of immunosuppression (n = 3), rituximab (n = 4), and steroids (n = 4). At mean 30-month follow-up, 4 patients (33.3%) were alive, 3 with and 1 without disease. Eight patients (67.6%) had died, 3 after lesional resolution and 5 with recurrent disease. Biopsies revealed mixed lymphoid infiltrates composed of atypical CD30-positive T cells (n = 5) or B cells (n = 7) with variable EBV-encoded small RNA expression. These cases suggest clinicopathologic presentations resembling lymphomatoid papulosis with atypical, large CD30-positive, EBV-positive cells could comprise first sign of potentially serious immunodeficiency and should prompt evaluation for EBV viremia. These cases also broaden the current picture of immunodeficiency-associated lymphoproliferative disorders to include lymphomatoid papulosis-like clinical presentations.

RESUMO

Harnessing the immune system to combat disease has revolutionized medical treatment. Monoclonal antibodies (mAbs), in particular, have emerged as important immunotherapeutic agents with clinical relevance in treating a wide range of diseases, including allergies, autoimmune diseases, neurodegenerative disorders, cancer, and infectious diseases. These mAbs are developed from naturally occurring antibodies and target specific epitopes of single molecules, minimizing off-target effects. Antibodies can also be designed to target particular pathogens or modulate immune function by activating or suppressing certain pathways. Despite their benefit for patients, the production and administration of monoclonal antibody therapeutics are laborious, costly, and time-consuming. Administration often requires inpatient stays and repeated dosing to maintain therapeutic levels, limiting their use in underserved populations and developing countries. Researchers are developing alternate methods to deliver monoclonal antibodies, including synthetic nucleic acid-based delivery, to overcome these limitations. These methods allow for in vivo production of monoclonal antibodies, which would significantly reduce costs and simplify administration logistics. This review explores new methods for monoclonal antibody delivery, including synthetic nucleic acids, and their potential to increase the accessibility and utility of life-saving treatments for several diseases.

RESUMO

INTRODUCTION AND HYPOTHESIS: At our institution, every patient seen by the gynecologic oncology service is screened for pelvic floor dysfunction. This study was aimed at determining if a combined surgical approach by gynecologic oncology and urogynecology services at our institution was feasible and safe for this patient population. METHODS: We performed a retrospective review of patients undergoing combined surgery by gynecologic oncology and urogynecology services at our institution from 2013 to 2021. Perioperative variables, postoperative adverse events, and long-term outcomes were assessed, and descriptive statistics were performed. RESULTS: From 20 December 2013 to 29 January 2021, a total of 102 patients underwent concurrent surgical repair of pelvic organ prolapse and/or stress urinary incontinence. Seventy-three patients (71.6%) had normal/benign pathologic conditions, and 29 (28.4%) had premalignant/malignant pathologic conditions. Ten patients (9.8%) had a postoperative complication, including reoperation for exposed midurethral sling (4.9%), urinary retention requiring midurethral sling release (2.9%), reoperation for hemoperitoneum (1.0%), and anemia requiring blood transfusion (1.0%). Nine complications occurred in patients with benign/normal pathologic conditions (12.3%), and one complication occurred in patients with pre-malignant/malignant pathologic conditions (3.4%). CONCLUSIONS: In our single-institution experience, concurrent gynecologic oncology and pelvic floor reconstructive surgery were safe and feasible in combination with no reported major morbidity events.

RESUMO

BACKGROUND: Patients suffering from advanced cancer often loose contact with their primary care physician (PCP) during oncologic treatment and palliative care is introduced very late. The aim of this pilot study was to test the feasibility and procedures for a randomized trial of an intervention to teach PCPs a palliative care approach and communication skills to improve advanced cancer patients' quality of life. METHODS: Observational pilot study in 5 steps. 1) Recruitment of PCPs. 2) Intervention: training on palliative care competencies and communication skills addressing end-of-life issues. 3) Recruitment of advanced cancer patients by PCPs. 4) Patients follow-up by PCPs, and assessment of their quality of life by a research assistant 5) Feedback from PCPs using a semi-structured focus group and three individual interviews with qualitative deductive theme analysis. RESULTS: Eight PCPs were trained. Patient recruitment was a challenge for PCPs who feared to impose additional loads on their patients. PCPs became more conscious of their role and responsibility during oncologic treatments and felt empowered to take a more active role picking up patient's cues and addressing advance directives. They developed interprofessional collaborations for advance care planning. Overall, they discovered the role to help patients to make decisions for a better end-of-life. CONCLUSIONS: While the intervention was acceptable to PCPs, recruitment was a challenge and a follow up trial was not deemed feasible using the current design but PCPs reported a change in paradigm about palliative care. They moved from a focus on helping patients to die better, to a new role helping patients to define the conditions for a better end-of-life. TRIAL REGISTRATION: The ethics committee of the canton of Geneva approved the study (2018-00077 Pilot Study) in accordance with the Declaration of Helsinki.

RESUMO

This report presents our experience in performing prolapse repair after anterior exenteration. The patient had a history of invasive bladder cancer and underwent a robotically assisted laparoscopic anterior exenteration with extended bilateral pelvic lymph node dissection and creation of an Indiana pouch continent diversion. Her pelvic organ prolapse progressed over time despite multiple pessary fittings. She eventually decided to proceed with pelvic reconstructive surgery 6 years after her cancer surgery. She underwent a successful vaginal native tissue reconstruction with uterosacral ligament suspension, posterior repair and reconstruction of the anterior compartment. The patient has been followed for 16 months without recurrent prolapse. Vaginal native tissue pelvic reconstruction is feasible in a patient with a history of pelvic exenteration.

RESUMO

In the MAPK pathway, an oncogenic V600E mutation in B-Raf kinase causes the enzyme to be constitutively active, leading to aberrantly high phosphorylation levels of its downstream effectors, MEK and ERK kinases. The V600E mutation in B-Raf accounts for more than half of all melanomas and ∼3% of all cancers, and many drugs target the ATP binding site of the enzyme for its inhibition. Because B-Raf can develop resistance against these drugs and such drugs can induce paradoxical activation, drugs that target allosteric sites are needed. To identify other potential drug targets, we generated and kinetically characterized an active form of B-RafV600E expressed using a bacterial expression system. In doing so, we identified an α-helix on B-Raf, found at the B-Raf-MEK interface, that is critical for their interaction and the oncogenic activity of B-RafV600E. We assessed the binding between B-Raf mutants and MEK using pull downs and biolayer interferometry and assessed phosphorylation levels of MEK in vitro and in cells as well as its downstream target ERK to show that mutating certain residues on this α-helix is detrimental to binding and downstream activity. Our results suggest that this B-Raf α-helix binding site on MEK could be a site to target for drug development to treat B-RafV600E-induced melanomas.

RESUMO

BACKGROUND: Among breast cancer survivors, urinary incontinence (UI) is often attributed to cancer therapy. We prospectively assessed urinary symptoms before and after (neo)adjuvant treatment of early-stage breast cancer. METHODS: With consent, women with stage I-III breast cancer completed the Urogenital Distress Inventory and the Incontinence Impact Questionnaire before and 3 months after initiating (neo)adjuvant therapy. Patients with UI were at least slightly bothered by urinary symptoms. If UI was present pretreatment, it was considered prevalent; if UI was new or worse at 3 months posttreatment, it was considered incident; if prevalent UI was no worse at 3 months posttreatment, it was considered stable. Ordinal logistic regression models identified characteristics associated with the level of prevalent UI and with the degree of UI impact on quality of life (QoL). RESULTS: On pretreatment surveys, participants (N=203; age 54.5 ± 11.4 years) reported 79.8% prevalence of UI, including overactive bladder (29.1%), stress incontinence (10.8%), or both (39.9%). The level of prevalent UI increased with body mass index (BMI; P<.05). Of 163 participants assessed at both time points, incident UI developed in 12 of 32 patients without prevalent UI and 27 of 131 patients with prevalent UI. Regardless of whether UI was prevalent (n=162), incident (n=39), or stable (n=94) at QoL assessment, the impact of UI increased (P<.01) with the number and severity of UI symptoms, subjective urinary retention, and BMI. Adjusted for those characteristics, incident UI had less impact on QoL (P<.05) than did prevalent or stable UI. CONCLUSIONS: We found that UI is highly prevalent at breast cancer diagnosis and that new or worsened UI is common after (neo)adjuvant therapy. Because UI often impairs QoL, appropriate treatment strategies are needed.

RESUMO

BACKGROUND: The response to COVID-19 catalyzed the adoption and integration of digital health tools into the health care delivery model for musculoskeletal patients. The change, suspension, or relaxation of Medicare and federal guidelines enabled the rapid implementation of these technologies. The expansion of payment models for virtual care facilitated its rapid adoption. The authors aim to provide several examples of digital health solutions utilized to manage orthopedic patients during the pandemic and discuss what features of these technologies are likely to continue to provide value to patients and clinicians following its resolution. CONCLUSION: The widespread adoption of new technologies enabling providers to care for patients remotely has the potential to permanently change the expectations of all stakeholders about the way care is provided in orthopedics. The new era of Digital Orthopaedics will see a gradual and nondisruptive integration of technologies that support the patient's journey through the successful management of their musculoskeletal disease.

RESUMO

A prospective observational cohort of 20 primary total hip arthroplasty (n = 12) and total knee arthroplasty (n = 8) patients (mean age: 63 ± 6 years) was passively monitored with a consumer-level wearable activity sensor before and 6 weeks after surgery. Patients were clustered by minimal change or decreased activity using sensor data. Decreased postoperative activity was associated with greater pain reduction (-5.5 vs -2.0, P = .03). All patients surpassed minimal clinical benefit thresholds of total joint arthroplasty (TJA) (Hip Disability and Osteoarthritis Score Junior 30.5 vs 20.8, P = .23; Knee Injury and Osteoarthritis Outcome Score Junior 23.3 vs 18.2, P = .77) within 6 weeks. Patients who objectively "take it easy" after TJA may experience less pain with no difference in early subjective outcome. Remote, passive analysis of outpatient wearable sensor data may permit real-time detection of early problems after TJA.

RESUMO

PURPOSE: The objective of this study was to investigate the prognostic role of three inflammatory markers: the neutrophil to lymphocyte ratio (NLR), the lymphocyte to monocyte ratio (LMR), and the platelet to lymphocyte ratio (PLR) as prognostic indicators in squamous cell carcinoma of the head and neck (HNSCC). METHODS: Patients with HNSCC treated with primary surgery, with or without adjuvant radiochemotherapy were enrolled. The preoperative NLR, LMR, and PLR were recorded. Confounding variables were also recorded: age, sex, BMI, comorbidities, performance status, AJCC T and N stage and HPV status. Endpoints were overall survival (OS) and event-free survival (EFS). Survival analysis was performed using Kaplan-Meier analysis, and multivariable analysis was performed using Cox proportional hazards regression. Survival models were evaluated using Harrell's concordance index (c-index). RESULTS: NLR (p = 0.2413), PLR (p = 0.1593), and LMR (p = 0.0552) were not significantly associated with OS in the multivariable analysis. With regard to EFS, low LMR (HR = 2.95, 95% CI 1.54-5.65, p = 0.001), high PLR (HR = 2.68, 95% CI 1.42-5.09, p = 0.003), and high NLR (HR = 3.37, 95% CI 1.7-6.69, p < 0.001) were associated with EFS. The multivariable c-index was highest for LMR (0.762), followed by NLR (0.761) and PLR (0.739). CONCLUSION: The LMR, PLR, and NLR were not associated with OS, but were associated with EFS in HNSCC. These markers are easily obtainable, and in the age of individualized patient care and precision medicine, they might represent further risk stratification tools for HNSCC patients.

RESUMO

IMPACT STATEMENT: Extracellular matrix (ECM) biomaterials were used to treat esophageal cancer patients after cancer resection and promoted regrowth of normal mucosa without recurrence of cancer. The present study investigates the mechanisms by which these materials were successful to prevent the cancerous phenotype. ECM downregulated neoplastic esophageal cell function (proliferation, metabolism), but normal esophageal epithelial cells were unaffected in vitro, and suggests a molecular basis (downregulation of PI3K-Akt, cell cycle) for the promising clinical results. The therapeutic effect appeared to be enhanced using homologous esophageal ECM. This study suggests that ECM can be further investigated to treat cancer patients after resection or in combination with targeted therapy.

RESUMO

BACKGROUND AND OBJECTIVE: To assess the relationship between retinal vascular and structural changes in the superficial, middle, and deep capillary plexuses (SCP, MCP, DCP) using optical coherence tomography angiography (OCTA) and en face OCT. PATIENTS AND METHODS: Patients with diabetic retinopathy were imaged using the Cirrus HD-OCT with AngioPlex. Using manual segmentation of the retinal layers, the authors compared OCTA to en face OCT images to examine corresponding patterns in each of the three capillary plexuses. RESULTS: Areas of decreased perfusion and capillary dropout on OCTA were found to be associated with three corresponding lesions on en face OCT: hyporeflectivity, cystic edema, and hard exudates. Vascular changes in individual capillary plexuses corresponded with structural changes in their respective perfused retinal layers. CONCLUSIONS: Using manual segmentation on OCTA, the authors provide a framework to visualize the relationship between vascular pathology on OCTA and structural changes on en face OCT within specific capillary plexuses.
