RESUMO

BACKGROUND: Cell phenotype switching is increasingly being recognized in atherosclerosis. However, our understanding of the exact stimuli for such cellular transformations and their significance for human atherosclerosis is still evolving. Intraplaque hemorrhage is thought to be a major contributor to plaque progression in part by stimulating the influx of CD163+ macrophages. Here, we explored the hypothesis that CD163+ macrophages cause plaque progression through the induction of proapoptotic endothelial-to-mesenchymal transition (EndMT) within the fibrous cap. METHODS: Human coronary artery sections from CVPath's autopsy registry were selected for pathological analysis. Athero-prone ApoE-/- and ApoE-/-/CD163-/- mice were used for in vivo studies. Human peripheral blood mononuclear cell-induced macrophages and human aortic endothelial cells were used for in vitro experiments. RESULTS: In 107 lesions with acute coronary plaque rupture, 55% had pathological evidence of intraplaque hemorrhage in nonculprit vessels/lesions. Thinner fibrous cap, greater CD163+ macrophage accumulation, and a larger number of CD31/FSP-1 (fibroblast specific protein-1) double-positive cells and TUNEL (terminal deoxynucleotidyl transferase-dUTP nick end labeling) positive cells in the fibrous cap were observed in nonculprit intraplaque hemorrhage lesions, as well as in culprit rupture sections versus nonculprit fibroatheroma sections. Human aortic endothelial cells cultured with supernatants from hemoglobin/haptoglobin-exposed macrophages showed that increased mesenchymal marker proteins (transgelin and FSP-1) while endothelial markers (VE-cadherin and CD31) were reduced, suggesting EndMT induction. Activation of NF-κB (nuclear factor kappa ß) signaling by proinflammatory cytokines released from CD163+ macrophages directly regulated the expression of Snail, a critical transcription factor during EndMT induction. Western blot analysis for cleaved caspase-3 and microarray analysis of human aortic endothelial cells indicated that apoptosis was stimulated during CD163+ macrophage-induced EndMT. Additionally, CD163 deletion in athero-prone mice suggested that CD163 is required for EndMT and plaque progression. Using single-cell RNA sequencing from human carotid endarterectomy lesions, a population of EndMT was detected, which demonstrated significant upregulation of apoptosis-related genes. CONCLUSIONS: CD163+ macrophages provoke EndMT, which may promote plaque progression through fibrous cap thinning.

RESUMO

HELIX syndrome (Hypohidrosis-Electrolyte disturbances-hypoLacrimia-Ichthyosis-Xerostomia) (MIM#617671) (ORPHA:528105), described in 2017, is due to an abnormal claudin 10 b protein, secondary to pathogenic CLDN10 variants. So far, only ten families have been described. We aim to describe the phenotype in the first Spanish family identified, highlight the skin anomalies as an important clue, and expand the genotypic spectrum. Two adult brothers from consanguineous parents with suspected ectodermal dysplasia (ED) since early childhood were re-evaluated. A comprehensive phenotypic exam and an aCGH + SNP4 × 180 K microarray followed by Sanger sequencing of the CLDN10 gene were performed. They presented hypohidrosis, xerosis, mild ichthyosis, plantar keratosis, palm hyperlinearity, alacrima, and xerostomia. In adulthood, they also developed a salt-losing nephropathy with hypokalemia and hypermagnesemia. The molecular study in both patients revealed a novel pathogenic homozygous deletion of 8 nucleotides in exon 2 of the CLDN10 gene [CLDN10 (NM_0006984.4): c.322_329delGGCTCCGA, p.Gly108fs*] leading to a premature truncation of the protein. Both parents were heterozygous carriers. Hypohidrosis, ichthyosis, and plantar keratosis associated with alacrima and xerostomia should raise suspicion for HELIX syndrome, which also includes nephropathy and electrolyte disturbances in adults. Given the potential for ED misdiagnosis in infancy, it is important to include the CLDN10 gene in a specific genodermatosis next-generation sequencing (NGS) panel to provide early diagnosis, accurate management, and genetic counseling.

RESUMO

Chronic inflammation drives the growth of colorectal cancer through the dysregulation of molecular pathways within the immune system. Infiltration of immune cells, such as macrophages, into tumoral regions results in the release of proinflammatory cytokines (IL-6; IL-17; TNF-α), fostering tumor proliferation, survival, and invasion. Tumors employ various mechanisms to evade immune surveillance, effectively 'cloaking' themselves from detection and subsequent attack. A comprehensive understanding of these intricate molecular interactions is paramount for advancing novel strategies aimed at modulating the immune response against cancer.

RESUMO

PURPOSE OF REVIEW: The aim of this systematic review was to investigate the effects of whole grain Avena sativa and Hordeum vulgare L., or their isolated fractions, on immune and inflammatory functions, as well as their influence on gut microbiota. A structured literature search was undertaken in line with PRISMA guidelines. Randomized controlled trials (RCTs) that investigated the effects of oats or barley consumption in adults and reported ≥ 1 of the following: C-reactive protein (CRP), tumor necrosis factor (TNF-α), interleukin-6 (IL-6), IL-2, IL-8, IL-18, lipopolysacharide binding protein (LBP) or gut microbiota-related outcomes, were included. RECENT FINDINGS: A total of 16 RCTs were included, among which 6 studies recruited metabolically at-risk population, including individuals with overweight and obesity, metabolic syndrome or hypercholesterolemia. Additionally, 3 trials involved young healthy population, 5 trials targeted older individuals (aged over 50 years), and 2 studies encompassed populations with other disease states. A total of 1091 individuals were included in the evaluation of short-term (up to 14 days) and long-term (beyond 14 days, up to 90 days) supplementation with oats or barley-based products. 9 studies measured inflammatory biomarkers and 5 of them reported significant reductions, specifically in long-term studies. Notably, no evidence of anti-inflammatory benefits was found in healthy individuals, whereas studies involving metabolically at-risk populations showed promising reductions in inflammation. 13 studies measured the impact on gut microbiota, and collectively suggest that oats and barley food products can influence the composition of gut microbiota, associated in some cases with metabolic improvements. Oats and barley consumption may confer anti-inflammatory effects in metabolically at-risk populations and influence gut microbiota outcomes. However, no anti-inflammatory benefits were observed in healthy individuals. Results from this systematic review suggests caution in interpreting findings due to limited trials and variations in interventions and health conditions.

RESUMO

BACKGROUND AND OBJECTIVES: Intracranial dissection is an important cause of stroke often with nonspecific angiographic features. Vessel wall imaging (VWI) can detect dissections, but intracranial applications remain unvalidated by pathologic specimens. We sought to determine the ability of VWI to identify the rarely reported spontaneous intracranial carotid dissection (sICD) guided by postmortem validation. METHODS: VWI features of sICD, validated by postmortem specimen analysis in 1 patient, included luminal enhancement within a hypoenhancing outer wall, narrowing the mid to distal ophthalmic (C6) segment, relatively sparing the communicating (C7) segment. VWI examinations were reviewed to identify patients (1) with matching imaging features, (2) no evidence of other vasculopathies (i.e., inflammatory, intracranial atherosclerotic disease [ICAD]), and (3) adequate image quality. These sICD VWI features were compared with those in patients with known ICAD causing similar narrowing of C6 and relative sparing of C7 by a Fisher exact test accounting for multiple samples. RESULTS: Among 407 VWI examinations, 8 patients were identified with 14 sICDs, all women aged 30-56 years, 6 (75%) bilateral. All patients with sICD had risk factors of dissection (e.g., recently postpartum, fibromuscular dysplasia, and hypertension) and 3 (37.5%) had intracranial dissections elsewhere. Seven (87.5%) were diagnosed as moyamoya syndrome on initial angiography. Enhancing lesions varied from thin flap-like defects (n = 6) to thick tissue along the superolateral wall of the internal carotid artery, within the hypoenhancing outer wall. Compared with 10 intracranial carotid plaques in 8 patients with ICAD, sICD demonstrated stronger (84.6% vs 20.0%, p = 0.003-0.025) and more homogeneous (61.5% vs 0.0%, p = 0.005-0.069) enhancement and less positive remodeling (0.0% vs 60.0%, p = 0.004-0.09). T1 hyperintensity was identified in 5 sICDs in 3 patients but not identified in ICAD. Three patients with serial imaging (8- to 39.8-month maximum intervals) revealed little to no changes in stenosis, wall thickening, or enhancement. DISCUSSION: sICD is distinguishable on VWI from ICAD by enhancement characteristics, less positive remodeling, and clinical parameters. These VWI features should raise suspicion especially in young women with risk factors of dissection. Temporal stability and a lack of T1 hyperintensity should not discourage diagnosing sICD.

RESUMO

INTRODUCTION AND IMPORTANCE: The incidence of acute pancreatitis varies globally, and its rates are increasing. Timely intervention in cases of infected necrosis is crucial to effective management. The landscape of acute pancreatitis management has undergone transformation through adopting a "step-up" strategy, accentuating the shift towards minimally invasive techniques. CASE PRESENTATION: A 63-year-old patient with acute pancreatitis and infected pancreatic necrosis underwent a challenging yet successful treatment using video-assisted retroperitoneal debridement employing a two-port approach facilitated access for an intricate area. The procedure, performed 45 days after admission, effectively reduced peripancreatic collections, demonstrating the efficacy of this approach in managing complex cases of infected pancreatic necrosis. CLINICAL DISCUSSION: The management of acute pancreatitis has evolved towards a comprehensive strategy involving early hydration, nutritional support, effective pain management, and interventions. Infected pancreatic necrosis poses a serious complication, with minimally invasive techniques such as video-assisted retroperitoneal debridement (VARD) emerging as preferred options. The efficacy and safety of VARD in complex cases are highlighted, although challenges persist, especially in extensive necrosis. CONCLUSION: The VARD procedure, a key component of the step-up approach, exhibits a remarkable safety profile, substantially reducing postoperative complications and mortality compared to open surgical counterparts. However, challenges persist in managing cases of infected Walled-Off Necrosis with deep extension, necessitating carefully considering a minimal-access approach. We report our experience using the VARD in a two-port approach.

RESUMO

OBJECTIVE: The aim of this study was to demonstrate that an adipocyte tissue-derived conditioned medium (ACM) contains inflammatory molecules that induce senescence in B cells. METHODS: We incubated blood-derived B cells from lean donors with ACM obtained from the adipose tissue of adult female donors with obesity undergoing weight reduction surgery or with medium as control. After 24 h, cells were harvested, and the expression of transcripts for proinflammatory cytokines (TNF/IL-6), chemokines (IL-8), and for markers of the senescence-associated secretory phenotype (SASP) was measured by quantitative polymerase chain reaction. B cells were also stained with the marker of immunosenescence ß-galactosidase, and their metabolic status was evaluated in Seahorse using a Mito Stress Test. RESULTS: We show that the incubation of B cells from lean donors with ACM induces the expression of transcripts for inflammatory and SASP transcripts, increases the amount of ß-galactosidase staining, and induces a metabolic phenotype characterized by higher basal and maximal oxygen consumption, spare respiratory capacity (difference between maximal and basal respiration), nonmitochondrial oxygen consumption, ATP production, and proton leak. CONCLUSIONS: These results demonstrate that B cells from lean individuals, after incubation with ACM, become inflammatory and senescent, and this occurs through metabolic pathways needed to support their secretory phenotype.

RESUMO

Anetoderma or macular atrophy is a rare skin condition of unclear pathogenesis, often associated with autoimmune diseases and skin damage from various infections. Human immunodeficiency virus (HIV), syphilis, and poxviruses have been implicated in the development of anetoderma. A 37-year-old male patient with HIV and recent unprotected sexual encounters presented with more than 400 skin lesions, consistent with Mpox. Symptomatic treatment for Mpox resulted in acute symptom resolution. However, 8 months later he developed papular anetoderma lesions in areas previously affected by Mpox. Biopsy confirmed the loss of elastic fibers in the affected skin areas, leading to the diagnosis of Mpox-induced anetoderma. This report presents a unique case of anetoderma following Mpox in an HIV-positive patient.

RESUMO

Chronic myelomonocytic leukaemia (CMML) is a rare haematological disorder characterized by monocytosis and dysplastic changes in myeloid cell lineages. Accurate risk stratification is essential for guiding treatment decisions and assessing prognosis. This study aimed to validate the Artificial Intelligence Prognostic Scoring System for Myelodysplastic Syndromes (AIPSS-MDS) in CMML and to assess its performance compared with traditional scores using data from a Spanish registry (n = 1343) and a Taiwanese hospital (n = 75). In the Spanish cohort, the AIPSS-MDS accurately predicted overall survival (OS) and leukaemia-free survival (LFS), outperforming the Revised-IPSS score. Similarly, in the Taiwanese cohort, the AIPSS-MDS demonstrated accurate predictions for OS and LFS, showing superiority over the IPSS score and performing better than the CPSS and molecular CPSS scores in differentiating patient outcomes. The consistent performance of the AIPSS-MDS across both cohorts highlights its generalizability. Its adoption as a valuable tool for personalized treatment decision-making in CMML enables clinicians to identify high-risk patients who may benefit from different therapeutic interventions. Future studies should explore the integration of genetic information into the AIPSS-MDS to further refine risk stratification in CMML and improve patient outcomes.

RESUMO

Introducción. La resección segmentaria del intestino y su derivación temporal o definitiva es un procedimiento frecuente en la práctica quirúrgica, que implica la construcción de un estoma. La enfermedad que lleva a la cirugía, las condiciones clínicas del paciente y los aspectos técnicos en la construcción de la ostomía son puntos claves en la evolución posoperatoria. Métodos. Se realizó una revisión de la literatura identificando las complicaciones asociadas a la construcción de estomas, con el objetivo de ofrecer herramientas de tratamiento y toma de decisiones al personal médico involucrado en la atención de estos pacientes. Resultados. La cirugía de urgencia, la inmunosupresión, la obesidad y la técnica en la apertura del orificio en la pared abdominal, favorecen la aparición de complicaciones tempranas que requieren manejo médico o reintervención quirúrgica. Conclusiones. Todo paciente con estoma debe ser valorado minuciosamente por el cirujano y la terapista enterostomal en las primeras 72 horas luego de la cirugía.


Introduction. Segmental resection of the intestine and its temporary or permanent bypass is a frequent procedure in surgical practice, which involves the construction of a stoma. The disease that leads to surgery, the clinical conditions of the patient and the technical aspects in the construction of the ostomy are key points in the postoperative evolution. Methods. A review of the literature was performed, identifying the complications associated with the construction of stomas, with the aim of offering treatment and decision-making tools to the medical personnel involved in the care of these patients. Results. Emergency surgery, immunosuppression, obesity, and the technique used to open the orifice in the abdominal wall favor the appearance of early complications that require medical management or surgical reintervention. Conclusions. Every patient with a stoma must be carefully evaluated by the surgeon and the enterostomal therapist in the first 72 hours after surgery.

RESUMO

Background: This study aimed to identify and describe indicators of depression, anxiety, body dissatisfaction, and risk of an eating disorder in patients who undergo plastic surgery. Methods: The sample was made up of 90 patients from a private clinic in Lima, Peru, with ages between 20 and 50 years. The participants were asked to answer the Aaron Beck Depression Inventory (BDI-II), the Aaron Beck Anxiety Inventory, the Body Shape Questionnaire, and the Abbreviated and Modified Eating Attitudes Scale (EAT - 26M). Results: Through data analysis with the SPSS statistical program, it was found that 80% of patients who access plastic surgery are women, and the average age is 32.4 years. Likewise, of the total sample, no anxiety traits have been identified; however, 3.3% present traits of moderate depression, pathological body discomfort, and risk of an eating disorder. Conclusion: The presurgical psychological evaluation in plastic surgery patients is crucial because it allows for the identification of predisposing factors to mental health problems and proposes support if needed.

RESUMO

The goal of our study is to compare the stability of the anatomic reconstruction of the anterior talofibular ligament (ATFL) with direct repair of the ATFL, in a cadaver model. We performed the following techniques in 18 cadaveric ankles: the intact ATFL was cut, after which a direct repair using 2 anchors was performed. The repair was sectioned, and anatomic reconstruction was then performed with a tendon autograft. We measured angular displacement in 3 anatomic planes (axial, coronal, sagittal) for each situation in response to the anterior drawer test (ADT), talar tilt test (TTT) and pivot test (PT), using a specifically constructed arthrometer. The sectioned ATFL was inferior to the intact ATFL in the axial plane with the ADT (p = .012), in the axial plane with the PT (p = .001) and in the axial and coronal planes with the TTT (p = .013 and p = .016, respectively). Direct anatomic repair was inferior to the intact ATFL in the axial plane upon the PT (p = .009). No differences could be found between anatomic graft reconstructions and the intact ATFL with any manoeuver, nor when comparing anatomic graft reconstruction and direct repair with 2 anchors. We were able to conclude that anatomic graft reconstruction of the ATFL reproduces angular stability of the native ligament in a cadaver model. While we could not detect if anatomic graft reconstruction was superior to direct repair, the latter proved to be less stable in the axial plane upon internal rotation (pivot test) versus the intact ATFL.

RESUMO

Introduction: People living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) often experience discrimination from both other individuals and the health personnel who care for them. Chile has experienced a marked increase in the number of new HIV cases.Methods: Prospective cross-sectional study. The HIV/AIDS questionnaire for providers and health personnel was obtained from the International Planned Parenthood Federation, initially carrying out a pilot test and evaluating its validity.Results: A total of 784 health professionals answered the questionnaire correctly. Among them, 68.4% (n = 536) were women, and 36.2% (n = 284) were physicians. The study revealed that more than 90% of respondents had a positive attitude towards caring for people living with HIV, and more than 75% did not mind buying food from them or sharing services with them. Furthermore, more than 99% rejected the religiously endorsed labeling of people living with HIV/AIDS as immoral. Additionally, 95.5% (n = 749) mentioned that they did not feel anxious about knowing whether the next patient on their care list was living with HIV, and 76.9% (n = 603) of the respondents felt safe taking blood samples.Conclusions: Chilean health professionals have good knowledge about HIV infection and its mode transmission. Their attitudes towards people living with HIV are also generally positive.

RESUMO

INTRODUCCIÓN: La seroprevalencia del SARS-CoV-2 en las enfermedades inflamatorias inmunomediadas (IMID) sigue siendo fuente de controversia. OBJETIVO: Comparar la seroprevalencia de anticuerpos (Ac) anti SARS-CoV-2 en pacientes con IMID en tratamientos con fármacos antirreumáticos modificadores de la enfermedad biológicos (FAMEb) o sintéticos dirigidos (FAMEsd) frente a un grupo de personas sin IMID. MÉTODOS: Estudio de pacientes con IMID y tratamientos con FAMEb y FAMEsd y de individuos sin IMID. Mediante la técnica de inmunoensayo por quimioluminiscencia indirecta, se determinaron las serologías IgG frente al SARS-CoV-2 entre octubre/2020 y mayo/2021. RESULTADOS: Se estudiaron 1.100 sujetos, 550 pacientes con IMID y 550 personas sin IMID. Se observó una seroprevalencia de 16% (88/550) en los pacientes frente a 19,3% (106/550) en el grupo de personas sin IMID, sin significación estadística (OR 0,790 [IC 95% 0,558-1,118]). Comparando los tratamientos con FAMEb o FAMEsd, se observó una tendencia a una menor seroprevalencia con rituximab, en relación con los individuos sin IMID (OR 0,296 [IC 95% 0,0871,007]). Asimismo, se encontró menor seroprevalencia en los pacientes que además de su FAMEb recibían tratamiento con metotrexato, en comparación con el grupo de personas sin IMID (OR 0,432 [IC 95% 0,223-0,835]). CONCLUSIONES: Las IMID en tratamiento con FAMEb o FAMEsd no influyen en la seroprevalencia frente al SARS-CoV-2 de los pacientes. El tratamiento concomitante con metotrexato disminuye de forma significativa la seroprevalencia en estos pacientes.


BACKGROUND: The seroprevalence of SARS-CoV-2 in immunemediated inflammatory diseases (IMID) remains controversial. AIM: To compare the seroprevalence of antibodies (Ab) to SARS-CoV-2 in patients with IMID receiving treatment with biological diseasemodifying antirheumatic drugs (bDMARD) or targeted synthetic (tsDMARD) versus a group of people without IMID. METHODS: Study of patients with IMID and treatments with bDMARD and tsDMARD and individuals without IMID. IgG serology against SARS-CoV-2 was measured using the two-step sandwich immunoassay technique by indirect chemiluminescence between October 2020 and May 2021. RESULTS: A total of 1100 subjects were studied, 550 patients with IMID and 550 persons without IMID. A seroprevalence of 16% (88/550) was observed in patients versus 19.3% (106/550) in the group of people without IMID, without statistical significance (OR 0.790 [95% CI 0.558-1.118]). Comparing the treatments with bD- MARD or tsDMARD, there was a tendency to lower seroprevalence with rituximab, in relation to individuals without IMID (OR 0.296 [95% CI 0.087-1.007]). In addition, lower seroprevalence was found in patients who received methotrexate treatment in addition to their bDMARD, compared to the group of individuals without IMID (OR 0.432 [95% CI 0.223-0.835]). CONCLUSIONS: IMIDs in treatment with bDMARDs or tsDMARDs do not influence the seroprevalence against SARS-CoV-2 in patients. Concomitant treatment with methotrexate significantly decreased seroprevalence in these patients.

RESUMO

Background: Rapid deployment aortic valve replacement (RD-AVR) has been recently introduced with encouraging results. Outcomes of isolated RD-AVR include good hemodynamic profile, facilitation of minimally invasive techniques, and reduction of surgical times. However, role of this prosthesis in concomitant surgery is not well known. Methods: In 2016, we formed a registry to monitor the introduction of this prosthesis, RApid Deployment Aortic Replacement (RADAR). We aim to report mid-term outcomes focusing on patients who had RD-AVR combined with other surgical procedures. Results: Between July 2012 and February 2021, 370 patients were included in this registry (mean age, 75.8±8.0 years; 64.32% male; mean EuroSCORE II, 3.5±2.8). Of these, 128 (34.59%) had concomitant procedures including myocardial revascularization surgery in 69 patients (53.91%), surgery on the ascending aorta in 34 (26.56%), and procedures on other valves in 10 patients (7.81%). There were no significant differences between the isolated AVR and concomitant AVR groups in postoperative complications, in-hospital mortality (4.72% vs. 3.32%, P=0.524), or hemodynamic behavior of these prostheses. Three-year survival was 83.73% and 89.89% in the isolated and concomitant AVR group respectively. There was no difference in survival between the two groups (log-rank test, P=0.4124). Conclusions: Our results support the safety and efficacy of the Edwards INTUITY valve system even in complex aortic valve disease with additional cardiac procedures. RD-AVR could become a useful tool for concomitant surgeries where surgical times are expected to be prolonged.

RESUMO

Background: Incidence of young patients (aged 40 years or younger) diagnosed with gastric carcinoma has increased worldwide. Young GC diagnosis, have clinicopathological features that differ from elderly, and is correlated with bad prognosis factors. The purpose of this work is to describe the prevalence, clinic-pathological features, and prognosis of overall survival (OS) of young Latin-American patients with GC. Methods: Retrospective, observational study. Included patients treated at the National Cancer Institute [2004-2020]. Statistical analysis: χ2 and t-test, Kaplan-Meier, Log-Rank and Cox-Regression. Statistical significance differences were assessed when P was bilaterally <0.05. Results: A total of 2,543 patients fulfilled the inclusion criteria. Young-patients were predominantly female (54%), with diffuse-type adenocarcinoma (68%), signet-ring-cell (72%), poor-differentiation (90%), and metastatic (79%). In OS analysis, patients with metastatic disease, showed differences regarding age, young patients reported a median-OS of 8 versus 13 months for elderly patients (P=0.001). Among young patients, differences were also observed regarding gender, young-female patients had a median-OS of 5 versus 11 months for young-man (P=0.001). Conclusions: This is one of the pioneer studies correlating age with gender and the prognostic features of bad prognosis in Latin-American population. Besides, supports the idea that a global effort is required to improve awareness, prevention, and early diagnosis of GC.

RESUMO

OBJECTIVE: The prevalence of chronic pain in Spain is 17%, which causes suffering and significant loss of quality of life. Therapies should not focus only on pain reduction, to improve function and quality of life are necessary. Currently, it is committed to combining drugs and other therapies such as relaxation, meditation, cognitive behavioral therapy, targeted exercises, healthy lifestyles and techniques to increase self-esteem and motivation for change. These therapies can be used as part of a multimodal approach, forming part of multicomponent programs or workshops. In this paper we proposed to evaluate the effectiveness of a workshop developed from the Hospital San Juan de Dios del Ajarafe, that integrated different non-pharmacological therapies in the control of chronic non-oncologic pain and to analyze patients' perceptions of the techniques applied and how they affected pain and lifestyles. METHODS: An intragroup before-after study (beginning-end of the workshop) was carried out, comparing pain, well-being, drug use, quality of life, and self-esteem. Surveys were conducted to deepen more qualitative aspects and identify improvements. The workshop consisted of psychoeducational action and training for the mental control of pain and emotions, based on the active participation of the patient in the management of his disease, promoting self-care and self-esteem, and aiming to improve well-being and quality of life. It consisted of 5 sessions of 3 hours (1 per week); of a group, interactive and practical nature. Statistical analysis was performed with SPSS vs.27.0. To compare related measures (before-after) we used Student's T tests for paired samples and Wilcoxon's test and to compare independent groups, Student's T and Mann Whitney's U; for the qualitative variables, we used Chi-Square and Fisher's test. RESULTS: Four workshops were evaluated in which 63 patients participated, with a mean age of 57.6 (SD:11.37) years, 60 (95.2%) of them were women. At the end of the workshop pain decreased 1.5 median (-2.0-0) and well-being increased 2.0 (0-2.0); quality of life increased a median of 0.121 (SD: 0.209), health status 16.8 (23.78) and self-esteem 2.74 (4.73); [p<0.001]. The best valued techniques were meditations, mainly mental analgesia, affirmations in the mirror and self-esteem techniques. CONCLUSIONS: Overall satisfaction with the workshop is 9.8 out of 10. There is a pain control and improvement in quality of life, self-perception of health status, well-being and self-esteem.


OBJETIVO: La prevalencia de dolor crónico en España es del 17% y causa sufrimiento y pérdida significativa de la calidad de vida. Las terapias no deben enfocarse sólo a la reducción del dolor, sino que es necesario mejorar la función y la calidad de vida. Actualmente, se apuesta por combinar fármacos y otras terapias como la relajación, meditación, terapia cognitivo conductual, ejercicios dirigidos, estilos de vida saludable y técnicas de aumento de la autoestima y motivación para el cambio. Estas terapias pueden ser utilizadas como parte de un abordaje multimodal, formando parte de programas o talleres multicomponente. En este trabajo nos planteamos evaluar la efectividad de un taller desarrollado en el Hospital San Juan de Dios del Aljarafe, que integraba distintas terapias no farmacológicas en el control del dolor crónico no oncológico y analizar las percepciones de los pacientes sobre las técnicas aplicadas y cómo afectaban al dolor y a sus estilos de vida. METODOS: Se realizó un estudio intragrupo antes-después (inicio-final del taller), comparando dolor, bienestar, consumo de fármacos, calidad de vida y autoestima. Se realizaron encuestas para profundizar en aspectos más cualitativos e identificar mejoras. El taller consistió en una acción psicoeducativa y de entrenamiento para el control mental del dolor y las emociones, fundamentada en la participación activa del paciente en el manejo de su enfermedad, promoviendo su autocuidado y autoestima, y persiguiendo mejorar el bienestar y calidad de vida. Constó de cinco sesiones de tres horas (una por semana); de carácter grupal, interactivo y práctico. El análisis estadístico se realizó con SPSS vs.27.0. Para comparar medidas relacionadas (antes-después) se realizaron las pruebas T de Student para muestras apareadas y test de Wilcoxon, y para comparar grupos independientes se usó la T de Student y U de Mann Whitney; para las variables cualitativas se empleó Chi-Cuadrado y test de Fisher. RESULTADOS: Se evaluaron cuatro talleres en los que participaron 63 pacientes, con 57,6 (SD:11,37) años de edad media, y de los que 60 (95,2%) fueron mujeres. Al finalizar el taller el dolor disminuyó 1,5 de mediana (-2,0-0) y el bienestar aumentó 2,0 (0-2,0); la calidad de vida aumentó una media de 0,121 (SD: 0,209), el estado de salud 16,8 (23,78) y la autoestima 2,74 (4,73) [p<0,001]. Las técnicas mejor valoradas fueron las meditaciones, principalmente la analgesia mental, las afirmaciones ante el espejo y las técnicas de autoestima. CONCLUSIONES: Hay satisfacción global con el taller con una puntuación de 9,8 sobre 10. Se constata el control del dolor y la mejora de la calidad de vida, la autopercepción del estado de salud, el bienestar y la autoestima.

RESUMO

Sesquiterpene lactones (SLs), plant-derived metabolites with broad spectra of biological effects, including anti-tumor and anti-inflammatory, hold promise for drug development. Primary cilia, organelles extending from cell surfaces, are crucial for sensing and transducing extracellular signals essential for cell differentiation and proliferation. Their life cycle is linked to the cell cycle, as cilia assemble in non-dividing cells of G0/G1 phases and disassemble before entering mitosis. Abnormalities in both primary cilia (non-motile cilia) and motile cilia structure or function are associated with developmental disorders (ciliopathies), heart disease, and cancer. However, the impact of SLs on primary cilia remains unknown. This study evaluated the effects of selected SLs (grosheimin, costunolide, and three cyclocostunolides) on primary cilia biogenesis and stability in human retinal pigment epithelial (RPE) cells. Confocal fluorescence microscopy was employed to analyze the effects on primary cilia formation (ciliogenesis), primary cilia length, and stability. The effects on cell proliferation were evaluated by flow cytometry. All SLs disrupted primary cilia formation in the early stages of ciliogenesis, irrespective of starvation conditions or cytochalasin-D treatment, with no effect on cilia length or cell cycle progression. Interestingly, grosheimin stabilized and promoted primary cilia formation under cilia homeostasis and elongation treatment conditions. Thus, SLs have potential as novel drugs for ciliopathies and tumor treatment.
