RESUMO
Major depressive disorder is the psychiatric disease with the highest global prevalence, impacting social functioning and decreasing the quality of life. The partial pathophysiological knowledge of the disease, the economic burden and the low remission rates are sufficient justification to carry out an update on the subject in the search for new therapeutic approaches and targets. The endocannabinoid system has been linked to the development of depression, and its stimulation or antagonism is a promising approach in the treatment of major depressive disorder. Cannabidiol (CBD) and its properties have been widely studied recently; its analgesic, anti-inflammatory, antineoplastic and neuroprotective roles have even been reported in animal models and clinical trials, achieving its approved use for certain neurodegenerative pathologies. The use of CBD in depression biomodels and clinical trials has not been the exception, and here we contrast the current evidence of its administration and pharmacology against the pathological mechanisms of major depressive disorder.
RESUMO
BACKGROUND: Chile presents one of the lowest organ donation rates, resulting in pediatric liver waitlist mortality rates up to 38.1%. Live donor liver transplantation is one of the main alternatives to decrease waitlist mortality, mostly utilized in our country for small children up to 20 kg. AIMS: The aim of this study was to report a three-case series of adult-to-pediatric living donor liver transplantation using a full left lobe graft. METHODS: We report three cases of children with more than 20 kg who received complete left hemi-grafts in different clinical scenarios. The indications and techniques adopted are discussed. RESULTS: Three children, two girls and one boy, aged 11, 7, and 3 years, were transplanted. The indications for transplant were fulminant hepatitis of autoimmune etiology, hepatoblastoma, and chronic liver failure due to autoimmune hepatitis, respectively. The evolution was satisfactory in all three children, and to date, all are well, approximately 12-24 months after the transplant. CONCLUSIONS: The use of a living donor left lateral segment (segments 2 and 3) has been successfully employed in pediatric liver transplantation. However, it is only suitable for infants and low-weight children. This approach using the whole left hemi-liver graft contributes to the reduction of small-for-size syndrome, mortality rate, and waiting times associated with deceased donors.

Acellular dermal matrix (ADM) is a useful adjunct in implant-based breast reconstruction. The benefits of using ADM with an expander as a temporary bridge to delayed autologous reconstruction are unknown. Placing prepectoral tissue expanders, without ADM, as a bridge to delayed autologous reconstruction could yield cost savings, shorten operating time and decrease complications. This investigation seeks to demonstrate the safety of placing prepectoral tissue expanders without ADM at the time of mastectomy as the first stage of autologous breast reconstruction. A retrospective, chart review was performed at our major academic institution between 2015 and 2020. Included were female patients, 18 years or older at the time of reconstruction, who underwent mastectomy with prepectoral tissue expander placement followed by autologous breast reconstruction at a delayed second stage. Excluded were patients of male gender, younger than 18, patients with lumpectomy only, subpectoral reconstruction, or immediate autologous reconstruction. Data on ADM, patient demographics, comorbidities, and cancer treatment were collected. There were 189 reconstructed breasts of which 56 (29.6 %) used ADM, 131 (69.3 %) did not use ADM, and 2 patients (1.1 %) of unknown ADM use. Expanders were in place for a mean time of 8.9±6.2 months. There was no statistically significant difference in complication rates between the ADM and no-ADM groups. Therefore, not wrapping prepectoral tissue expanders in ADM, at the time of mastectomy, has an equivalent rate of complications compared to ADM wrapping among patients who go on to have second stage autologous breast reconstruction.
RESUMO
Background: Implant-based breast reconstruction following radiotherapy can lead to significant postoperative complications. Closed-incision negative pressure wound therapy (ciNPWT) has emerged as a potential intervention to reduce these complications. Objectives: To assess the effectiveness of ciNPWT in reducing postoperative complications in patients undergoing implant-based breast reconstruction after radiotherapy. Methods: A retrospective single-center cohort study was conducted, including patients who underwent implant-based breast reconstruction after mastectomy and radiotherapy between January 1, 2015, and December 31, 2022. We utilized a procedure-level analysis model with patients contributing distinct observations for multiple procedures. Our primary outcome measures included fluid collection, infection, and wound complications. Propensity score analysis was employed to adjust for potential confounders, such as BMI, smoking history, and diabetes history, creating a balanced comparison between the ciNPWT-treated and untreated groups. Results: In our study of 301 breast reconstructions postradiotherapy from 2015 to 2022, encompassing 218 unique patients, we found significant benefits of ciNPWT. During an average of 2.2-year follow-up, the ciNPWT group demonstrated no infections, contrasting with a 10.4% rate in the non-ciNPWT group (P < .0001). Wound complications were also significantly lower in the ciNPWT group (1.9% vs 11.2%; P = .00848). Demographic differences were adjusted using inverse probability of treatment weights. The findings suggest ciNPWT's promising role in enhancing postoperative outcomes in breast reconstruction postradiotherapy. Conclusions: Our study suggests that the use of ciNPWT in implant-based breast reconstruction postradiotherapy can potentially reduce postoperative complications. This intervention can improve patient outcomes and may offer cost-saving benefits in the long run.
RESUMO
Introduction: For patients with drug-resistant epilepsy, successful localization and surgical treatment of the epileptogenic zone (EZ) can bring seizure freedom. However, surgical success rates vary widely because there are currently no clinically validated biomarkers of the EZ. Highly epileptogenic regions often display increased levels of cortical excitability, which can be probed using single-pulse electrical stimulation (SPES), where brief pulses of electrical current are delivered to brain tissue. It has been shown that high-amplitude responses to SPES can localize EZ regions, indicating a decreased threshold of excitability. However, performing extensive SPES in the epilepsy monitoring unit (EMU) is time-consuming. Thus, we built patient-specific in silico dynamical network models from interictal intracranial EEG (iEEG) to test whether virtual stimulation could reveal information about the underlying network to identify highly excitable brain regions similar to physical stimulation of the brain. Methods: We performed virtual stimulation in 69 patients that were evaluated at five centers and assessed for clinical outcome 1 year post surgery. We further investigated differences in observed SPES iEEG responses of 14 patients stratified by surgical outcome. Results: Clinically-labeled EZ cortical regions exhibited higher excitability from virtual stimulation than non-EZ regions with most significant differences in successful patients and little difference in failure patients. These trends were also observed in responses to extensive SPES performed in the EMU. Finally, when excitability was used to predict whether a channel is in the EZ or not, the classifier achieved an accuracy of 91%. Discussion: This study demonstrates how excitability determined via virtual stimulation can capture valuable information about the EZ from interictal intracranial EEG.
RESUMO
BACKGROUND: One of the main limitations to achieving a complete tumor resection in patients with technically resectable liver tumors is the presence of a small future liver remnant (FLR). Portal vein embolization (PVE) allows hypertrophy of the non-embolized lobe, reducing the risk of postoperative liver failure. AIM: To describe the experience of portal embolization prior to hepatectomy and its effectiveness in converting advanced unresectable liver tumors into resectable tumors. METHODS: Non-concurrent cohort study. All patients who underwent PVE before hepatectomy between 2016 and 2020 in our center were included. Demographic and diagnostic variables, pre and post-PVE volumes, perioperative variables, and global and disease-free survival were analyzed. RESULTS: Nineteen patients were included. Median age 66 (54-72) years and 57.9% (n= 11) were women. Bilateral metastases were present in 78.9% (n= 15). Sixteen patients (84.2%) received neoadjuvant chemotherapy. One patient (5.3%) had a complication after PVE. The median time between embolization and volumetry was 5.3 weeks (4.7-7.1). Median FLR before and after PVE were 19.8% (16.2-27.7) and 30% (25.2-40.5), respectively. The median percentage of hypertrophy was 48% (40.4-76.5). Fifteen patients (78.9%) underwent hepatectomy. Significant complications occurred in 26.6% (n= 4); among them, three patients (20%) presented postoperative liver failure. CONCLUSIONS: PVE is safe and effective in promoting FLR hypertrophy in the presence of chemotherapy, allowing patients with advanced liver tumors to undergo surgery with curative intent.

A choledochal cyst is a rare condition that requires surgical treatment to prevent complications, such as obstructive jaundice, cyst rupture, cholangitis, and the risk of malignancy. Complete cyst excision is considered the best option, as it reduces the risk of inflammation and the development of cholangiocarcinoma. Therefore, cholecystectomy and complete cyst resection followed by reconstruction with a Roux-en-Y hepaticojejunostomy is the treatment of choice. We present a case (with video) that shows the complete resection of a type I choledochal cyst with Roux-en-Y reconstruction of two separate ducts since the right posterior duct reached the cyst independently. The laparoscopic approach offers all the advantages of mini-invasive surgery and better visualization of the structures; however, biliary reconstruction to fine ducts implies a surgical challenge that requires high training in mini-invasive surgery.
RESUMO
Introduction: Fanconi anemia (FA) is an inherited disorder characterized by bone marrow failure, congenital malformations, and predisposition to malignancies. Alterations in hematopoietic stem cells (HSC) have been reported, but little is known regarding the bone marrow (BM) stroma. Thus, the characterization of Mesenchymal Stromal Cells (MSC) would help to elucidate their involvement in the BM failure. Methods: We characterized MSCs of 28 FA patients (FA-MSC) before and after treatment (hematopoietic stem cell transplantation, HSCT; or gene therapy, GT). Phenotypic and functional properties were analyzed and compared with MSCs expanded from 26 healthy donors (HD-MSCs). FA-MSCs were genetically characterized through, mitomycin C-test and chimerism analysis. Furthermore, RNA-seq profiling was used to identify dysregulated metabolic pathways. Results: Overall, FA-MSC had the same phenotypic and functional characteristics as HD-MSC. Of note, MSC-GT had a lower clonogenic efficiency. These findings were not confirmed in the whole FA patients' cohort. Transcriptomic profiling identified dysregulation in HSC self-maintenance pathways in FA-MSC (HOX), and was confirmed by real-time quantitative polymerase chain reaction (RT-qPCR). Discussion: Our study provides a comprehensive characterization of FA-MSCs, including for the first time MSC-GT and constitutes the largest series published to date. Interestingly, transcript profiling revealed dysregulation of metabolic pathways related to HSC self-maintenance. Taken together, our results or findings provide new insights into the pathophysiology of the disease, although whether these niche defects are involved in the hematopoietic defects seen of FA deserves further investigation.
RESUMO
While cytostatic chemotherapy targeting DNA is known to induce genotoxicity, leading to cell cycle arrest and cytokine secretion, the impact of these drugs on fibroblast-epithelial cancer cell communication and metabolism remains understudied. Our research focused on human breast fibroblast RMF-621 exposed to nonlethal concentrations of cisplatin and doxorubicin, revealing reduced proliferation, diminished basal and maximal mitochondrial respirations, heightened mitochondrial ROS and lactate production, and elevated MCT4 protein levels. Interestingly, RMF-621 cells enhanced glucose uptake, promoting lactate export. Breast cancer cells MCF-7 exposed to conditioned media (CM) from drug-treated stromal RMF-621 cells increased MCT1 protein levels, lactate-driven mitochondrial respiration, and a significantly high mitochondrial spare capacity for lactate. These changes occurred alongside altered mitochondrial respiration, mitochondrial membrane potential, and superoxide levels. Furthermore, CM with doxorubicin and cisplatin increased migratory capacity in MCF-7 cells, which was inhibited by MCT1 (BAY-8002), glutamate dehydrogenase (EGCG), mitochondrial pyruvate carrier (UK5099), and complex I (rotenone) inhibitors. A similar behavior was observed in T47-D and ZR-75-1 breast cancer cells. This suggests that CM induces metabolic rewiring involving elevated lactate uptake to sustain mitochondrial bioenergetics during migration. Treatment with the mitochondrial-targeting antioxidant mitoTEMPO in RMF-621 and the addition of an anti-CCL2 antibody in the CM prevented the promigratory MCF-7 phenotype. Similar effects were observed in THP1 monocyte cells, where CM increased monocyte recruitment. We propose that nonlethal concentrations of DNA-damaging drugs induce changes in the cellular environment favoring a promalignant state dependent on mitochondrial bioenergetics.
RESUMO
Resumen Introducción: La polifarmacia inapropiada en adultos mayores con demencia es un problema de salud pública global. En este artículo se describen las indicaciones y se dan pautas para la deprescripción de potenciadores cognitivos (inhibidores de acetilcolinesterasa y memantina) y psicofármacos en pacientes con demencia. Materiales y métodos: Esta es una revisión narrativa a partir del estado del arte sobre la deprescripción en el anciano con demencia. Resultados: La deprescripción no significa limitar esfuerzos terapéuticos, por el contrario, consiste en una estrategia de prevención cuaternaria para reducir el riesgo de reacciones adversas e identificar escenarios donde el beneficio clínico es marginal. Para esto, es necesario rastrear activamente a pacientes con demencia con indicación de deprescripción (falta de respuesta clínica adecuada, desaparición del beneficio con el uso prolongado, estadio de demencia grave o fase terminal). Discusión: Los procesos de deprescripción varían según el grupo farmacológico e incluyen disminuciones progresivas de la medicación, así como el seguimiento y la monitorización para evitar el empeoramiento clínico. Se requiere de programas de educación médica en deprescripción para estudiantes y profesionales en ejercicio, especialmente en servicios de atención primaria en áreas rurales o dispersas, lo cual configura un llamado urgente a la neurología, la psiquiatría y la geriatría. Conclusión: El proceso de deprescripción en el paciente con demencia puede implementarse bajo criterios específicos y de una forma organizada.
Abstract Introduction: Inappropriate polypharmacy in older adults with dementia is a global public health problem. This article describes the indications and gives guidelines for the deprescription of cognitive enhancers (acetylcholinesterase inhibitors and memantine), and psychotropic drugs in patients with dementia. Materials and methods: This is a narrative review article based on the state of the art on deprescribing in the elderly with dementia. Results: Deprescribing does not mean limiting therapeutic efforts; on the contrary, it consists of a quaternary prevention strategy to reduce the risk of adverse reactions and identify scenarios where the clinical benefit is marginal. For this, it is necessary to actively track patients with dementia with an indication for deprescription (lack of adequate clinical response, disappearance of benefit with prolonged use, severe dementia, or palliative phase). Discussion: Deprescribing processes vary depending on the pharmacological group and include progressive reductions in medication, as well as follow-up and monitoring to avoid clinical worsening. Medical education programs in deprescribing are required for students and practicing professionals, especially in primary care services in rural or dispersed areas, which constitutes an urgent call for neurology, psychiatry, and geriatrics. Conclusion: The deprescription process in patients with dementia can be implemented under specific criteria and in an organized manner.
RESUMO
Background: Advances in multiple myeloma (MM) treatment have shifted the therapeutic landscape. Understanding patients' perspectives can assist physicians in helping patients make informed decisions. This study aimed to understand the patient decision-making process and gain insights into patient perspectives on B-cell maturation antigen (BCMA)-targeted therapies for MM. Methods: An 18-question survey was completed by patients with MM enrolled in HealthTree® Cure Hub, an online portal helping patients with plasma cell dyscrasias navigate their disease. Results: From October 28, 2022, to January 12, 2023, 325 patients with MM participated in the survey. The mean age (standard deviation) of the respondents was 66 (8) years; 54% were female and 90% were White. Among 218 patients with complete clinical records in the database, the median (min, max) lines of therapy (LOT) was 2 (1,16). Among 61 (28%) patients who had received ≥4 LOTs, 55 (90%) were triple-class exposed. Of the 290 patients who responded to the question about openness to new therapies, 76 (26%) were open to trying a new therapy immediately and 125 (43%) wanted more information on safety and efficacy. Most respondents reported likely or very likely to try a BCMA CAR T-cell therapy (60%) or a bispecific antibody (74%) and some needed more information to decide (16% for CAR T-cell therapy and 13% for bispecific antibody). The most requested information included efficacy, side effects (SEs), eligibility, and administration process for both CAR T-cell and bispecific therapies. When 2 therapies with the same efficacy and duration of response were offered, 69% of respondents would prefer the therapy with a lower risk of severe SEs but requires continuous dosing with no treatment-free interval, and 31% preferred a therapy given once followed by a treatment-free interval but with a potentially higher risk of severe SEs. To receive an effective therapy, the top acceptable trade-offs included frequent monitoring of SEs and initiating a new therapy in a hospital setting, and the least acceptable compromise was caregiver burden. Conclusions: This study found a high level of openness in patients with MM to try BCMA-targeted therapies. Information on efficacy, safety, availability, and eligibility may assist patients on decision-making.
RESUMO
Background: Implant-based breast augmentation is a gold standard procedure for transfeminine patients to create a more feminine-appearing chest. In many cases, ancillary procedures are performed simultaneously to achieve an optimal aesthetic result. Objectives: To determine the clinical outcomes of patients undergoing feminizing gender-affirming breast surgery in a single academic institution. Methods: A retrospective electronic chart review of feminizing gender-affirming breast surgery patients at Mayo Clinic, Rochester, from 2017 to 2022 was conducted. Patients' demographics and surgical outcomes were gathered. A survival analysis was performed to obtain the time-to-event complication rate. Results: Over 5 years, 46 patients (92 breasts) were included. The mean age was 39 years (standard deviation [SD] ±15), and most had an above-normal body mass index (BMI) (58.7%). Thirty (65%) had previous gender-affirming surgeries. The mean implant volume was 289â mL (SD ±95; 140-520). Most implants were placed in a subglandular plane (81%) with an inframammary fold incision (91.3%). All implants used were smooth, round cohesive silicone gel implants. Ancillary procedures were performed in 32 patients (69.57%). Eight patients presented complications (4 major vs 4 minor) in a median postoperative follow-up of 372 vs 392 days; at 1-month follow-up, the probability of a complication having occurred is 2.17% (95% CI: 0%-6.3%) vs 5% (95% CI: 0%-11.5%), and at 1 year, the probability is 10.21% (95% CI: 0%-20.9%) vs 12.5% (95% CI: 0%-23.4%), which remains the same up to 4 years. Conclusions: Breast augmentation with implants is a safe procedure to achieve feminization of the breast with a low rate of complications.
RESUMO
Cytogenetic studies are essential in the diagnosis and follow up of patients with bone marrow failure syndromes (BMFSs), but obtaining good quality results is often challenging due to hypocellularity. Optical Genome Mapping (OGM), a novel technology capable of detecting most types chromosomal structural variants (SVs) at high resolution, is being increasingly used in many settings, including hematologic malignancies. Herein, we compared conventional cytogenetic techniques to OGM in 20 patients with diverse BMFSs. Twenty metaphases for the karyotype were only obtained in three subjects (15%), and no SVs were found in any of the samples. One patient with culture failure showed a gain in chromosome 1q by fluorescence in situ hybridization, which was confirmed by OGM. In contrast, OGM provided good quality results in all subjects, and SVs were detected in 14 of them (70%), mostly corresponding to cryptic submicroscopic alterations not observed by standard techniques. Therefore, OGM emerges as a powerful tool that provides complete and evaluable results in hypocellular BMFSs, reducing multiple tests into a single assay and overcoming some of the main limitations of conventional techniques. Furthermore, in addition to confirming the abnormalities detected by conventional techniques, OGM found new alterations beyond their detection limits.

Breast cancer is the most common invasive neoplasm and the leading cause of cancer death in women worldwide. The main cause of mortality in cancer patients is invasion and metastasis, where the epithelial-mesenchymal transition (EMT) is a crucial player in these processes. Pharmacological therapy has plants as its primary source, including isoflavonoids. Brazilin is an isoflavonoid isolated from Haematoxilum brasiletto that has shown antiproliferative activity in several cancer cell lines. In this study, we evaluated the effect of Brazilin on canonical markers of EMT such as E-cadherin, vimentin, Twist, and matrix metalloproteases (MMPs). By Western blot, we evaluated E-cadherin, vimentin, and Twist expression and the subcellular localization by immunofluorescence. Using gelatin zymography, we determined the levels of secretion of MMPs. We used Transwell chambers coated with matrigel to determine the in vitro invasion of breast cancer cells treated with Brazilin. Interestingly, our results show that Brazilin increases 50% in E-cadherin expression and decreases 50% in vimentin and Twist expression, MMPs, and cell invasion in triple-negative breast cancer (TNBC) MDA-MB-231 and to a lesser extend in MCF7 ER+ breast cancer cells. Together, these findings position Brazilin as a new molecule with great potential for use as complementary or alternative treatment in breast cancer therapy in the future.

CONTEXT: Transgender and gender diverse (TGD) individuals have greater access to genital surgery (GS) with improved insurance coverage and access to trained surgeons and interdisciplinary gender-affirming providers. OBJECTIVE: To determine perioperative medical and behavioral health outcomes in transfeminine (TF) individuals undergoing GS, with use of a specific gender-affirming hormone therapy (GAHT) algorithm based on individualized risk factor assessment. METHODS: In this retrospective observational cohort study, we collected preoperative and postoperative data from 183 TF individuals at a single tertiary referral center from 2017 to 2022, grouping patients by those who continued estradiol (Group 1) vs those who had temporarily discontinued estradiol for 2 to 6 weeks preoperatively (Group 2). Data included clinical and biochemical assessment, GAHT regimens, validated behavioral health measures, and postoperative complications. Main outcomes included venous thromboembolism (VTE) incidence, non-VTE postoperative complication incidence, and change in behavioral health assessments. RESULTS: The majority of individuals continued estradiol perioperatively (Group 1; 138 [75.4%]). Individuals who temporarily held estradiol preoperatively (Group 2; 45 [24.6%]) were statistically older (P < .01), had higher incidence of cardiometabolic comorbidities (P < .01), and higher Caprini scores (P < .01). Group 1 was statistically more likely to use oral estradiol (P < .01). One episode (0.05%) of VTE occurred (Group 1). There was no significant difference in postoperative complications or behavioral health measures between groups. CONCLUSION: An individualized algorithm for preoperative hormone management for TF GS resulted in perioperative continuation of GAHT for the majority of individuals without significantly increasing the risk for postoperative surgical complications, while maintaining stable behavioral health measures perioperatively.

Pediatric optic pathway/hypothalamic gliomas (OPHG) pose challenges in treatment due to their location and proximity to vital structures. Surgical resection plays a key role in the management of OPHG especially when the tumor exhibits mass effect and causes symptoms. However, data regarding outcomes and complications of surgical resection for OPHG remains heterogenous. The authors performed a systematic review on pediatric OPHG in four databases: PubMed, EMBASE, Cochrane Library, and Google Scholar. We included studies that reported on the visual outcomes and complications of OPHG resection. A meta-analysis was performed and reported per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A total of 26 retrospective studies were included. Seven hundred ninety-seven pediatric patients with OPHG undergoing surgical resection were examined. A diagnosis of NF1 was confirmed in 9.7%. Gross total resection was achieved in 36.7%. Intraorbital optic pathway gliomas showed a significantly higher gross total resection rate compared to those located in the chiasmatic/hypothalamic region (75.8% vs. 9.6%). Postoperatively, visual acuity improved in 24.6%, remained unchanged in 68.2%, and worsened in 18.2%. Complications included hydrocephalus (35.4%), anterior pituitary dysfunction (19.6%), and transient diabetes insipidus (29%). Tumor progression post-resection occurred in 12.8%, through a mean follow-up of 53.5 months. Surgical resection remains an essential strategy for treating symptomatic and large pediatric OPHG and can result in favorable vision outcomes in most patients. Careful patient selection is critical. Patients should be monitored for hydrocephalus development postoperatively and followed up to assess for tumor progression and adjuvant treatment necessity.

Introduction: The purpose of this study is to produce a bibliometric review of the 30 most cited articles related to 6 major domains of body contouring-abdominoplasty, thighplasty, brachioplasty, gluteoplasty, body lift, and liposuction-for resident and fellow education. Methods: The authors utilized the Web of Science Citation Index to identify the 30 most cited articles related to surgery for body contouring published from 1975 to 2020. Articles were classified according to their level of evidence, type of study, and country of publication. Results: A total of 336 articles were reviewed to compile our list. The mean number of citations across the articles was 114.7 ± SD 86.1. The highest prevalence of the papers was published between 2000 and 2009 (n = 15, 50%). The country with the highest number of contributions was the United States (n = 22, 73%). Plastic and Reconstructive Surgery served as the main journal of publication for these papers (n = 22, 73.3%). The majority of articles were designated for clinical-type studies (n = 26, 86.7%). No basic science or prevalence study design papers were listed. In terms of level of evidence (LoE), most papers were assigned IV (n = 11, 36.7%) and III (n = 7, 23.3%). Conclusions: Our study reveals that the most cited papers in body contouring are of LoE III and IV. Although the LoE of plastic surgery research, in general, has improved, in the past decade, a call for higher quality papers remains. Overall, this analysis provides an easy, electronic starting point for residents and fellows interested in understanding the field's evolution.

Les articles contenaient un nombre moyen de 114,7± ÉT 86,1 citations. La plus forte prévalence d'articles a été publiée entre 2000 et 2009 (n = 15, 50 %). La majorité des articles provenaient des États-Unis d'Amérique (n = 22, 73 %), et c'est la revue Plastic and Reconstructive Surgery© qui en a publié le plus (n = 22, 73,3 %). La plupart des articles prenaient la forme d'études de type clinique (n = 26, 86,7 %). Aucun article de science fondamentale ni étude de prévalence n'a été répertorié. Pour ce qui est de la qualité des preuves, la plupart des articles ont obtenu un classement de IV (n = 11, 36,7 %) et de III (n = 7, 23,3 %). Conclusions : L'étude révèle que la qualité de preuve de la plupart des articles dans ce domaine était de III et IV. Même si la chirurgie plastique se prête moins bien aux études randomisées et contrôlées que la médecine, elle mérite des articles comportant une meilleure qualité de preuves. Grâce à la présente analyse, les résidents et les étudiants en stage de perfectionnement peuvent accéder rapidement et facilement à des concepts influents pour comprendre l'évolution du domaine par voie électronique. Termes MeSH : abdominoplastie, bibliométrie, chirurgie plastique, études transversales, liposuccion, remodelage corporel.
RESUMO
Portal vein thrombosis is a rare complication after laparoscopic sleeve gastrectomy, a widely performed bariatric surgery procedure. Occasionally, the development of portal vein thrombosis can progress to more severe conditions, including portal hypertension and cavernomatosis, thereby presenting a complex and challenging clinical scenario. The management of such complications often requires careful consideration; however, surgical intervention in the form of a splenorenal shunt is an exceptional indication. We present the case of a 33-year-old female patient who had previously undergone laparoscopic sleeve gastrectomy in 2014 and subsequently developed portal thrombosis, followed by cavernomatosis and associated complications of portal hypertension. A proximal splenorenal shunt procedure and splenectomy were successfully performed to manage portal hypertension. The presentation of this clinical case aims to contribute to the available evidence and knowledge surrounding this rare and challenging pathology.
RESUMO
In patients with drug-resistant epilepsy (DRE) who are not candidates for resective surgery, various thalamic nuclei, including the anterior, centromedian, and pulvinar nuclei, have been extensively investigated as targets for neuromodulation. However, the therapeutic effects of different targets for thalamic neuromodulation on various types of epilepsy are not well understood. Here, we present a 32-year-old patient with multifocal bilateral temporoparieto-occipital epilepsy and bilateral malformations of cortical development (MCDs) who underwent bilateral stereoelectroencephalographic (SEEG) recordings of the aforementioned three thalamic nuclei bilaterally. The change in the rate of interictal epileptiform discharges (IEDs) from baseline were compared in temporal, central, parietal, and occipital regions after direct electrical stimulation (DES) of each thalamic nucleus. A significant decrease in the rate of IEDs (33% from baseline) in the posterior quadrant regions was noted in the ipsilateral as well as contralateral hemisphere following DES of the pulvinar. A scoping review was also performed to better understand the current standpoint of pulvinar thalamic stimulation in the treatment of DRE. The therapeutic effect of neuromodulation can differ among thalamic nuclei targets and epileptogenic zones (EZs). In patients with multifocal EZs with extensive MCDs, personalized thalamic targeting could be achieved through DES with thalamic SEEG electrodes.

Introduction: The clinical success of chimeric antigen receptor-modified T cells (CAR-T cells) for hematological malignancies has not been reproduced for solid tumors, partly due to the lack of cancer-type specific antigens. In this work, we used a novel combinatorial approach consisting of a versatile anti-FITC CAR-T effector cells plus an FITC-conjugated neuroblastoma (NB)-targeting linker, an FITC-conjugated monoclonal antibody (Dinutuximab) that recognizes GD2. Methods: We compared cord blood (CB), and CD45RA-enriched peripheral blood leukapheresis product (45RA) as allogeneic sources of T cells, using peripheral blood (PB) as a control to choose the best condition for anti-FITC CAR-T production. Cells were manufactured under two cytokine conditions (IL-2 versus IL-7+IL-15+IL-21) with or without CD3/CD28 stimulation. Immune phenotype, vector copy number, and genomic integrity of the final products were determined for cell characterization and quality control assessment. Functionality and antitumor capacity of CB/45RA-derived anti-FITC CAR-T cells were analyzed in co-culture with different anti-GD2-FITC labeled NB cell lines. Results: The IL-7+IL-15+IL-21 cocktail, in addition to co-stimulation signals, resulted in a favorable cell proliferation rate and maintained less differentiated immune phenotypes in both CB and 45RA T cells. Therefore, it was used for CAR-T cell manufacturing and further characterization. CB and CD45RA-derived anti-FITC CAR-T cells cultured with IL-7+IL-15+IL-21 retained a predominantly naïve phenotype compared with controls. In the presence of the NB-FITC targeting, CD4+ CB-derived anti-FITC CAR-T cells showed the highest values of co-stimulatory receptors OX40 and 4-1BB, and CD8+ CAR-T cells exhibited high levels of PD-1 and 4-1BB and low levels of TIM3 and OX40, compared with CAR-T cells form the other sources studied. CB-derived anti-FITC CAR-T cells released the highest amounts of cytokines (IFN-γ and TNF-α) into co-culture supernatants. The viability of NB target cells decreased to 30% when co-cultured with CB-derived CAR-T cells during 48h. Conclusion: CB and 45RA-derived T cells may be used as allogeneic sources of T cells to produce CAR-T cells. Moreover, ex vivo culture with IL-7+IL-15+IL-21 could favor CAR-T products with a longer persistence in the host. Our strategy may complement the current use of Dinutuximab in treating NB through its combination with a targeted CAR-T cell approach.
