Superior prognostic accuracy of FIGO staging system in primary female genital tract lymphomas: A retrospective study (IELSG35).

Primary lymphoma of the female genital tract (PLFGT) is a rare type of extranodal lymphoma. In this retrospective study from the International Extranodal Lymphoma Study Group, we analyzed clinical data from 60 women diagnosed with PLFGT between 1982 and 2012. The median age was 52 years. Limited stage, as defined by the Ann Arbor and FIGO staging systems, was observed in 55% and 63% of cases, respectively. The uterus was the primary site of lymphoma in 25 cases, with the ovaries as the second most common site (n = 24). The most common histological subtype was diffuse large B-cell lymphoma (DLBCL, n = 44), followed by follicular lymphoma and marginal zone lymphoma (6 patients each). Two patients received surgery alone as first-line therapy, while 58 underwent systemic therapy, 16 following major surgery. Thirteen patients received consolidation radiotherapy and six were given central nervous system (CNS) prophylaxis. Twenty patients had disease progression or recurrence. Six patients with DLBCL (14%) experienced CNS relapse, which was the only site of recurrence in five of them. All but one patient with CNS relapse had primary ovarian involvement, and three had bulky disease; none of these patients had received CNS prophylaxis. With a median follow-up of 60 months, the median overall survival of the DLBCL cohort was approximately 13 years, with a 5-year survival rate of 77%. In multivariable analysis, advanced disease according to the FIGO system was the only parameter significantly associated with shorter overall, cause-specific, and progression-free survival in patients with DLBCL.

Follicular Lymphoma in Chile in the Adult Public Cancer Program: The Impact of Chemoimmunotherapy.

BACKGROUND: Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma (NHL) in the United States and Europe. However, data on FL from Latin America are scant. AIMS: This study aims at better understand the clinical features, treatment patterns and outcomes of patients with FL in Chile. Of special interest was to evaluate POD24 as an adverse marker. METHODS AND RESULTS: We collected retrospective data from 722 patients 15 years or older diagnosed with FL and treated in 17 cancer centers in Chile between 2000 and 2019. Time to first treatment (TTFT), progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Cox proportional-hazard regression models were fitted to investigate prognostic factor. The median age at diagnosis was 62 with a female predominance (63%); 73% of patients had advance stage disease and 68% had bone marrow involvement; 63% had intermediate or high FLIPI scores. The 1-year TTFT rate was 96%, and 30% of patients received chemoimmunotherapy. Adding rituximab to chemotherapy was associated with a higher complete response (69% vs. 60%; p < 0.001) and superior median OS (16 vs. 8 years; p < 0.001). Patients who experience POD24 had an inferior median OS (2.4 vs. 15 years). CONCLUSION: Our study shows a female predominance in patients with FL in Chile and confirms superior response and survival outcomes with adding rituximab to chemotherapy. Our study also confirms a poor OS in patients who experience POD24.

[Cardiotoxicity from anti-HER-2 therapies in patients with HER-2 positive breast cancer]. / Cardiotoxicidad por terapias anti-HER-2 en pacientes con cáncer de mama HER-2 positivo.

Background: HER-2 positive (+) breast cancer (BC) accounts for 20-25% of BC, it is more aggressive, and it has a lower survival rate. Since the approval of trastuzumab in 1998, other HER-2-targeted therapies such as pertuzumab and trastuzumab emtansine (TDM1) have been introduced, improving patient survival. However, cardiotoxicity is an adverse effect of these treatments. Objective: To estimate the incidence of cardiotoxicity with trastuzumab, trastuzumab/pertuzumab, and TDM1 in women with HER-2 + BC treated over a 6-year period at the Hospital de Clínicas and the Hospital Departamental de Soriano. Material and methods: Observational, descriptive, and retrospective study which included patients with HER-2 + BC treated with trastuzumab, trastuzumab/pertuzumab, or TDM1. Results: 81 patients were included, with a cardiotoxicity incidence of 23.4%. Cardiotoxicity was determined by a > 10% decrease in left ventricular ejection fraction (LVEF) (57.9%) and a LVEF < 50% evident during treatment (42.1%). Only 1 patient presented symptomatic heart failure. 63.1% of those who discontinued treatment due to cardiotoxicity managed to resume it. No relationship was evident between cardiovascular history or the administration regimen and the development of cardiotoxicity. Conclusion: The study showed a cardiotoxicity incidence similar to the international one. Most did not present cardiac toxicity, and if they did, it was asymptomatic and reversible.

Introducción: el cáncer de mama (CM) HER-2 positivo (+) representa el 20-25% de los CM, es más agresivo y tiene menor sobrevida. Desde la aprobación del trastuzumab en 1998, se han introducido otras terapias dirigidas al HER-2 como pertuzumab y trastuzumab emtansina (TDM1), con lo cual ha mejorado la supervivencia de las pacientes. Sin embargo, la cardiotoxicidad representa un efecto adverso de estos tratamientos. Objetivo: estimar la incidencia de cardiotoxicidad con trastuzumab, trastuzumab/pertuzumab y TDM1 en mujeres con CM HER-2 +, tratadas en un periodo de 6 años en el Hospital de Clínicas y el Hospital Departamental de Soriano. Material y métodos: estudio observacional, descriptivo y retrospectivo que incluyó pacientes con CM HER-2 +, tratadas con trastuzumab, trastuzumab/pertuzumab o TDM1. Resultados: se incluyeron 81 pacientes. La incidencia de cardiotoxicidad fue del 23.4%. La cardiotoxicidad se determinó por una disminución > 10% de la fracción de ejección del venticulo izquierdo (FEVI) (57.9%) y por una FEVI < 50%, evidenciada durante el tratamiento (42.1%). Únicamente una paciente presentó insuficiencia cardiaca sintomática. El 63.1% de quienes suspendieron el tratamiento por cardiotoxicidad logró reanudarlo. No se evidenció una relación entre los antecedentes cardiovasculares ni con el esquema de administración y el desarrollo de cardiotoxicidad. Conclusión: el estudio mostró una incidencia de cardiotoxicidad similar a la internacional. La mayoría no tuvo toxicidad cardiaca y si la hubo fue asintomática y reversible.

Molecular mechanisms of cancer cachexia. Role of exercise training.

Cancer-associated cachexia represents a multifactorial syndrome mainly characterized by muscle mass loss, which causes both a decrease in quality of life and anti-cancer therapy failure, among other consequences. The definition and diagnostic criteria of cachexia have changed and improved over time, including three different stages (pre-cachexia, cachexia, and refractory cachexia) and objective diagnostic markers. This metabolic wasting syndrome is characterized by a negative protein balance, and anti-cancer drugs like chemotherapy or immunotherapy exacerbate it through relatively unknown mechanisms. Due to its complexity, cachexia management involves a multidisciplinary strategy including not only nutritional and pharmacological interventions. Physical exercise has been proposed as a strategy to counteract the effects of cachexia on skeletal muscle, as it influences the mechanisms involved in the disease such as protein turnover, inflammation, oxidative stress, and mitochondrial dysfunction. This review will summarize the experimental and clinical evidence of the impact of physical exercise on cancer-associated cachexia.

Dietary supplementation with plant extracts for amelioration of persistent myofascial discomfort in the cervical and back regions: a randomized double-blind controlled study.

Background: Back pain is a common health problem that affects both workers and older people, reducing their quality of life. The primary objective was to assess the effect of dietary supplementation with plant extracts of rosemary, ashwagandha, and sesame consumed for 12 weeks on the intensity of back pain. Methods: A single-center randomized double-blind study with three parallel arms depending on the product consumed. The duration of treatment was 12 weeks. The investigational product, Berelief®, contained a blend of three polyphenolic standardized extracts: rosemary (Rosmarinus officinalis L.), ashwagandha (Withania somnifera L.), and sesame (Sesamum indicum L.) seed. Two doses were tested: low dose (400 mg) and high dose (800 mg). There were 42 subjects in the placebo group, 39 in the low dose and 42 in the high dose groups. Study variables included back pain intensity [VAS score, Patient-Reported Outcomes Measurement Information System (PROMIS-29), and Cornell Musculoskeletal Discomfort Questionnaire; functionality Roland-Morris Disability (RMD) questionnaire]; quality of life (QoL) [36-item Short Form Survey (SF-36), the Beck Depression Inventory-II (BDI-II), the State-Trait Anxiety Inventory (STAI), and the Perceived Stress Scale (PSS)]; sleep quality [accelerometer and Pittsburgh Sleep Quality Index (PSQI)]. Results: The improvement in back pain recorded by the visual analogue scale (VAS) at the study visits after the beginning of treatment, as well as on a weekly basis recorded in the diary card was significantly higher in the intervention group than in the placebo group (p < 0.044 dose-low; p < 0.005 dose-high). Significant differences in pain intensity of the PROMIS-29 (p = 0.002) and upper back pain in the Cornell questionnaire (p = 0.011) in favour of the investigational product were found. Furthermore, benefits in improving health-related quality of life, mood and sleep quality were also detected. Conclusion: Dietary supplementation for 12 weeks of a blend of polyphenolic standardized extracts of rosemary, ashwagandha, and sesame was effective in reducing the intensity of pain in subjects with chronic myofascial cervical and back pain.

Update of the guidelines for the pharmacological treatment of rheumatoid arthritis by the Mexican College of Rheumatology 2023.

OBJECTIVE: To develop updated guidelines for the pharmacological management of rheumatoid arthritis (RA). METHODS: A group of experts representative of different geographical regions and various medical services catering to the Mexican population with RA was formed. Questions based on Population, Intervention, Comparison, and Outcome (PICO) were developed, deemed clinically relevant. These questions were answered based on the results of a recent systematic literature review (SLR), and the evidence's validity was assessed using the GRADE system, considered a standard for these purposes. Subsequently, the expert group reached consensus on the direction and strength of recommendations through a multi-stage voting process. RESULTS: The updated guidelines for RA treatment stratify various therapeutic options, including different classes of DMARDs (conventional, biologicals, and JAK inhibitors), as well as NSAIDs, glucocorticoids, and analgesics. By consensus, it establishes the use of these in different subpopulations of interest among RA patients and addresses aspects related to vaccination, COVID-19, surgery, pregnancy and lactation, and others. CONCLUSIONS: This update of the Mexican guidelines for the pharmacological treatment of RA provides reference points for evidence-based decision-making, recommending patient participation in joint decision-making to achieve the greatest benefit for our patients. It also establishes recommendations for managing a variety of relevant conditions affecting our patients.

The effect of antipsychotic medications on QTc and delirium in paediatric cardiac patients with ICU delirium.

OBJECTIVE: Children with prolonged hospital admissions for CHD often develop delirium. Antipsychotic medications (APMs) have been used to treat delirium but are known to prolong the QTc duration. There is concern for prolongation of the QTc interval in cardiac patients who may be more vulnerable to electrocardiogram (ECG) changes and may have postoperative QTc prolongation already. The goal of this study was to determine the effect of APM on QTc duration in postoperative paediatric cardiac patients and determine the effect of quetiapine and risperidone in treating delirium and QTc prolongation. DESIGN: Retrospective study, July 1, 2017-May 31, 2022. SETTING: Tertiary children's hospital. PATIENTS: Included were patients admitted to the paediatric cardiac ICU at Children's Healthcare of Atlanta. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: ECGs, delirium scores, and drug information were collected. Delirium was defined as Cornell Assessment of Pediatric Delirium (CAPD) score >9. Mixed effect models were performed to evaluate the effect of surgery on QTc change and the effect of antipsychotics on QTc and CAPD changes. There were 139 children, 55% male and 67% surgical admissions. Median age was 5.9 months. Mean QTc increased after cardiac surgery by 18 ms (p = 0.014, 95% CI 3.65-32.4). There was no significant change in QTc after antipsychotic administration (p = 0.064). The mean CAPD score decreased (12.5-7.2; p < 0.001). Quetiapine had the most improvement in delirium, and risperidone had the least improvement (77.8%, n = 14; 37.8%, n = 34, respectively; p = 0.002). CONCLUSIONS: The QTc interval did not have a statistically significant change after the administration of antipsychotics, while there was improvement in the CAPD score. APMs may be administered safely without significant prolongation of the QTc and are an effective treatment for delirium.

Long-term outcome of peripheral T-cell lymphomas: Ten-year follow-up of the International Prospective T-cell Project.

Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of haematological cancers with generally poor clinical outcomes. However, a subset of patients experience durable disease control, and little is known regarding long-term outcomes. The International T-cell Lymphoma Project (ITCLP) is the largest prospectively collected cohort of patients with PTCLs, providing insight into clinical outcomes at academic medical centres globally. We performed a long-term outcome analysis on patients from the ITCLP with available 10-year follow-up data (n = 735). The overall response rate to first-line therapy was 68%, while 5- and 10-year overall survival estimates were 49% and 40% respectively. Most deaths occurred prior to 5 years, and for patients alive at 5 years, the chance of surviving to 10 years was 84%. However, lymphoma remained the leading cause of death in the 5- to 10-year period (67%). Low-risk International Prognostic Index and Prognostic Index for T-cell lymphoma scores both identified patients with improved survival, while in multivariate analysis, age >60 years and Eastern Cooperative Oncology Group performance status 2-4 were associated with inferior outcomes. The favourable survival seen in patients achieving durable initial disease control emphasizes the unmet need for optimal front-line therapeutic approaches in PTCLs.

Diagnóstico y tratamiento de extravasación salival asociado a glándulas salivales BlandinNuhn: Reporte de caso clínico y revisión de la literatura / Diagnosis and treatment of salivary extravasation associated with BlandinNuhn salivary glands: Clinical case report and literature review

Los mucoceles son lesiones de extravasación salival asociados a la ruptura de los conductos que generalmente se asocian con trauma. Son azuláceos, con aspecto traslúcido, fluctuantes a la palpación, expansivos y de crecimiento rápido. Mayoritariamente se manifiestan en población joven. El sitio más común de localización es la mucosa de labio inferior, sin embargo, pueden presentarse en cualquier zona que contenga glándulas salivales menores, como vientre de lengua, donde se encuentran las glándulas Blandin-Nuhn. La frecuencia de las lesiones asociadas a éstas glándulas es del 2.25% reportándose aproximadamente 400 casos hasta la fecha. La finalidad de ésta publicación es la descripción de una patología infrecuente, así como realizar una revisión a la literatura. Se presenta el caso de una niña de tres años con historia de aumento de volumen congénito en el dorso de la lengua sin síntomas compatibles con mucocele, se realiza biopsia excisional bajo anestesia general. El resultado del estudio histopatológico reporta: fenómeno de extravasación de mucosa. Paciente evoluciona satisfactoriamente. Estas lesiones expansivas pueden repercutir en el desenvolvimiento normal de la vida de las personas causando dislalia, disfagia y disnea. El tratamiento de este tipo de lesiones en la infancia favorece a un adecuado desarrollo del habla y mejora las condiciones de alimentación.

Mucoceles are salivary extravasation lesions associated with rupture of ducts that are generally associated with trauma. They are bluish, translucent in appearance, fluctuating on palpation, expansive and fast growing. They mostly occur in young people. The most common site of location is the mucosa of the lower lip, however, they can occur in any area that contains minor salivary glands, such as the belly of the tongue, where the Blandin-Nuhn glands are located. The frequency of lesions associated with Blandin-Nuhn's glands is 2.25%, with approximately 400 cases reported to date. The purpose of this publication is the description of an uncommon pathology, as well as a review of the literature. The case of a three-year-old female with a history of congenital volume increase at the dorsum of the tongue without symptoms compatible with mucocele is reported, an excisional biopsy was performed under general anesthesia. The result of the histopathological study reports: extravasation mucus phenomenon. Patient evolves satisfactorily. These expansive lesions can affect the normal development of people's lives, causing dyslalia, dysphagia and dyspnea. Treatment of this type of injuries in childhood favors adequate speech development and improves feeding conditions.

Edema pulmonar por reexpansión. Reporte de Caso / Pulmonary edema due to re-expansion. Case Report

Introducción. El edema pulmonar por reexpansión es una complicación poco frecuente, secundaria a una rápida reexpansión pulmonar posterior al drenaje por toracentesis o toracostomía cerrada. Al día de hoy, se ha descrito una incidencia menor al 1 % tras toracostomía cerrada, con mayor prevalencia en la segunda y tercera década de la vida. Su mecanismo fisiopatológico exacto es desconocido; se ha planteado un proceso multifactorial de daño intersticial pulmonar asociado con un desequilibrio de las fuerzas hidrostáticas. Caso clínico. Presentamos el caso de un paciente que desarrolló edema pulmonar por reexpansión posterior a toracostomía cerrada. Se hizo una revisión de la literatura sobre esta complicación. Resultados. Aunque la clínica sugiere el diagnóstico, la secuencia de imágenes desempeña un papel fundamental. En la mayoría de los casos suele ser autolimitado, por lo que su manejo es principalmente de soporte; sin embargo, se han reportado tasas de mortalidad que alcanzan hasta el 20 %, por tanto, es importante conocer los factores de riesgo y las medidas preventivas. Conclusión. El edema pulmonar de reexpansión posterior a toracostomía es una complicación rara en los casos con neumotórax, aunque es una complicación que se puede presentar en la práctica diaria, por lo cual debe tenerse en mente para poder hacer el diagnóstico y un manejo adecuado.

Introduction. Re-expansion pulmonary edema is a rare complication secondary to rapid pulmonary re-expansion after drainage by thoracentesis and/or closed thoracostomy. As of today, an incidence of less than 1% has been described after closed thoracostomy, with a higher prevalence in the second and third decades of life. Its exact pathophysiological mechanism is unknown; a multifactorial process of lung interstitial damage associated with an imbalance of hydrostatic forces has been proposed. Clinical case. We present the case of a patient who developed pulmonary edema due to re-expansion after closed thoracostomy, conducting a review of the literature on this complication. Results. Although the clinic suggests the diagnosis, the sequence of images plays a fundamental role. In most cases, it tends to be a self-limited disease, so its management is mainly supportive. However, mortality rates of up to 20% have been recorded. Therefore, it is important to identify patients with major risk factors and initiate preventive measures in these patients. Conclusions. Re-expansion pulmonary edema after thoracostomy is a rare complication in cases with pneumothorax; however, it is a complication that can occur in daily practice. Therefore, it must be kept in mind to be able to make the diagnosis and an adequate management.

Influence of mesh nebulizer characteristics on aerosol delivery in non-human primates.

Non-Human Primates (NHPs) are particularly relevant for preclinical studies during the development of inhaled biologics. However, aerosol inhalation in NHPs is difficult to evaluate due to a low lung deposition fraction and high variability. The objective of this study was to evaluate the influence of mesh nebulizer parameters to improve lung deposition in macaques. We developed a humidified heated and ventilated anatomical 3D printed macaque model of the upper respiratory tract to reduce experiments with animals. The model was compared to in vivo deposition using 2D planar scintigraphy imaging in NHPs and demonstrated good predictivity. Next, the anatomical model was used to evaluate the position of the nebulizer on the mask, the aerosol particle size and the aerosol flow rate on the lung deposition. We showed that placing the mesh-nebulizer in the upper part of the mask and in proximal position to the NHP improved lung delivery prediction. The lower the aerosol size and the lower the aerosol flow rate, the better the predicted aerosol deposition. In particular, for 4.3 ± 0.1 µm in terms of volume mean diameter, we obtained 5.6 % ± 0.2 % % vs 19.2 % ± 2.5 % deposition in the lung model for an aerosol flow rate of 0.4 mL/min vs 0.03 mL/min and achieved 16 % of the nebulizer charge deposited in the lungs of macaques. Despite the improvement of lung deposition efficiency in macaques, its variability remained high (6-21 %).

Association between use of enhanced recovery after surgery protocols and postoperative complications after gastric surgery for cancer (POWER 4): a nationwide, prospective multicentre study.

INTRODUCTION: The effectiveness of the Enhanced Recovery After Surgery (ERAS) protocols in gastric cancer surgery remains controversial. METHODS: Multicentre prospective cohort study of adult patients undergoing surgery for gastric cancer. Adherence with 22 individual components of ERAS pathways were assessed in all patients, regardless of whether they were treated in a self-designed ERAS centre. Each centre had a three-month recruitment period between October 2019 and September 2020. The primary outcome was moderate-to-severe postoperative complications within 30 days after surgery. Secondary outcomes were overall postoperative complications, adherence to the ERAS pathway, 30 day-mortality and hospital length of stay (LOS). RESULTS: A total of 743 patients in 72 Spanish hospitals were included, 211 of them (28.4 %) from self-declared ERAS centres. A total of 245 patients (33 %) experienced postoperative complications, graded as moderate-to-severe complications in 172 patients (23.1 %). There were no differences in the incidence of moderate-to-severe complications (22.3% vs. 23.5%; OR, 0.92 (95% CI, 0.59 to 1.41); P = 0.068), or overall postoperative complications between the self-declared ERAS and non-ERAS groups (33.6% vs. 32.7%; OR, 1.05 (95 % CI, 0.70 to 1.56); P = 0.825). The overall rate of adherence to the ERAS pathway was 52% [IQR 45 to 60]. There were no differences in postoperative outcomes between higher (Q1, > 60 %) and lower (Q4, ≤ 45 %) ERAS adherence quartiles. CONCLUSIONS: Neither the partial application of perioperative ERAS measures nor treatment in self-designated ERAS centres improved postoperative outcomes in patients undergoing gastric surgery for cancer.

Conclusions: major ambulatory surgery is a care modality well accepted by patients and their accompanying families.

Incidence and clinical significance of FLT3 and nucleophosmin mutation in childhood acute myeloid leukemia in Chile

Abstract Introduction Acute myeloid leukemia (AML) is a heterogeneous disease and approximately one-third of its carriers do not have evident genetic abnormalities. The mutation of specific molecular markers, such as fms-like tyrosine kinase 3 (FTL3) internal tandem duplication (ITD), FLT3 tyrosine kinase domain (TKD) and nucleophosmin (NPM1), are associated with an adverse and favorable prognosis, respectively. Objective The objective was to determine the prevalence of FLT3/ITD and NPM1 in Chilean patients and their association with clinical data and prognosis. Method and Results Two hundred and thirty-two children were studied between 2011 and 2017, the median being 8.6 years (ranging from 1 to 18 months). Acute promyelocytic leukemia (APL) was diagnosed in 29%. The FLT3/ITD-mutated in non-promyelocytic AML was at 10% (14/133) and the FLT3/TKD, at 3.7% (2/54). In APL, it was at 25.4% (16/63). In non-promyelocytic AML, the FLT3/ITD-mutated was associated with a high leucocyte count, the median being 28.5 x mm3 (n= 14) versus 19.4 x mm3 (n= 119), (p= 0.25), in non-mutated cases. In APL, the median was 33.6 x mm3 (n= 15) versus 2.8 x mm3 (n= 47), (p < 0.001). The five-year overall survival (OS) in non-promyelocytic AML with non-mutated and mutated FLT3/ITD were 62.7% and 21.4%, respectively, (p < 0.001); the 5-year event-free survival (EFS) were 79.5% and 50%, respectively, (p < 0.01). The five-year OS in APL with non-mutated and mutated FLT3/ITD was 84.7% and 62.5%, respectively, (p= 0.05); the 5-year EFS was 84.7% and 68.8%, respectively, (p= 0.122). The NPM1 mutation was observed in 3.2% (5/155), all non-promyelocytic AML with the normal karyotype. Conclusion The FLT3/ITD mutation was observed more frequently in APL and associated with a higher white cell count at diagnosis. However, the most important finding was that the FLT3/ITD mutation was associated with a shorter survival in non-promyelocytic AML.

Long-term follow-up of an IgA nephropathy cohort: outcomes and risk factors.

AIM: IgA nephropathy (IgAN), the most common glomerulopathy worldwide and in Uruguay, raised treatment controversies. The study aimed to analyze long-term IgAN outcomes and treatment. METHODS: A retrospective analysis of a Uruguayan IgAN cohort, enrolled between 1985 and 2009 and followed up until 2020, was performed. The Ethics Committee approved the study. The inclusion criteria were (a) biopsy-proven IgAN; (b) age ≥12 years; and (c) available clinical, histologic, and treatment data. The patients were divided into two groups, with immunosuppressive (IS) or without (NoIS) treatment. Outcomes (end-stage kidney disease/kidney replacement therapy [ESKD/KRT] or all-cause death) were obtained from mandatory national registries. RESULTS: The study population included 241 patients (64.7% men), median age 32 (19.5) years, baseline blood pressure <130/80 mmHg in 37%, and microhematuria in 67.5% of patients. Baseline proteinuria, glomerulosclerosis, and a higher crescent percentage were significantly more frequent in the IS group. Proteinuria improved in both groups. Renal survival at 20 years was 74.6% without difference between groups. In the overall population and in the NoIS group, bivariate Cox regression analysis showed that baseline proteinuria, endocapillary hypercellularity, tubule interstitial damage, and crescents were associated with a higher risk of ESKD/KRT or death, but in the IS group, proteinuria and endocapillary hypercellularity were not. In the multivariate Cox analysis, proteinuria in the NoIS group, crescents in the IS group and tubule interstitial damage in both groups were independent risk factors. CONCLUSION: The IS group had more severe risk factors than the NoIS group but attained a similar outcome.

Incidence and clinical significance of FLT3 and nucleophosmin mutation in childhood acute myeloid leukemia in Chile.

INTRODUCTION: Acute myeloid leukemia (AML) is a heterogeneous disease and approximately one-third of its carriers do not have evident genetic abnormalities. The mutation of specific molecular markers, such as fms-like tyrosine kinase 3 (FTL3) internal tandem duplication (ITD), FLT3 tyrosine kinase domain (TKD) and nucleophosmin (NPM1), are associated with an adverse and favorable prognosis, respectively. OBJECTIVE: The objective was to determine the prevalence of FLT3/ITD and NPM1 in Chilean patients and their association with clinical data and prognosis. METHOD AND RESULTS: Two hundred and thirty-two children were studied between 2011 and 2017, the median being 8.6 years (ranging from 1 to 18 months). Acute promyelocytic leukemia (APL) was diagnosed in 29%. The FLT3/ITD-mutated in non-promyelocytic AML was at 10% (14/133) and the FLT3/TKD, at 3.7% (2/54). In APL, it was at 25.4% (16/63). In non-promyelocytic AML, the FLT3/ITD-mutated was associated with a high leucocyte count, the median being 28.5 x mm3 (n = 14) versus 19.4 x mm3 (n = 119), (p = 0.25), in non-mutated cases. In APL, the median was 33.6 x mm3 (n = 15) versus 2.8 x mm3 (n = 47), (p < 0.001). The five-year overall survival (OS) in non-promyelocytic AML with non-mutated and mutated FLT3/ITD were 62.7% and 21.4%, respectively, (p < 0.001); the 5-year event-free survival (EFS) were 79.5% and 50%, respectively, (p < 0.01). The five-year OS in APL with non-mutated and mutated FLT3/ITD was 84.7% and 62.5%, respectively, (p = 0.05); the 5-year EFS was 84.7% and 68.8%, respectively, (p = 0.122). The NPM1 mutation was observed in 3.2% (5/155), all non-promyelocytic AML with the normal karyotype. CONCLUSION: The FLT3/ITD mutation was observed more frequently in APL and associated with a higher white cell count at diagnosis. However, the most important finding was that the FLT3/ITD mutation was associated with a shorter survival in non-promyelocytic AML.

Intestinal permeability and low-grade chronic inflammation in schizophrenia: A multicentre study on biomarkers. Rationale, objectives, protocol and preliminary results.

BACKGROUND: Altered intestinal permeability and low-grade chronic inflammation disrupt the integrity of the blood-brain barrier (microbiota-gut-brain axis), probably playing a role in the pathophysiology of schizophrenia-spectrum disorders. However, studies assessing the microbiota-gut-brain axis are inconsistent. This article describes the rationale, objectives, protocol, and presents descriptive results for a new project. METHODS: The sample of this study came from an observational, cross-sectional and multisite study including four centers in Spain (PI17/00246) recruiting adult patients with DSM-5 schizophrenia-spectrum disorders at any stage of the disease. The aims of the project are to assess the interrelation between intestinal permeability and low-grade chronic inflammation in schizophrenia-spectrum disorders and the role of peripheral biomarkers, diet, exercise, metabolic syndrome, disease severity and functioning as well as cognition. Assessments included the following variables: (1) anthropometric, (2) intestinal permeability, diet, and physical exercise, (3) clinical and functional, (4) neuropsychological and cognitive reserve, and (5) peripheral biomarkers from blood. RESULTS: A total of 646 patients were enrolled (257, 39.7% female). Mean age was 43.2±13.6 years, illness duration 15.1±11.5 years. 55.8% consumed tobacco. Positive PANSS score was 13.68±6.55, and 20.38±8.69 in the negative symptoms. CGI was 4.16±2.22 and GAF was 60.00±14.84. CONCLUSION: The results obtained by this project are expected to contribute toward the understanding of the physiopathology of schizophrenia-spectrum disorders. This will likely aid to personalize treatments in real-world clinical practice, potentially including variables related to intestinal permeability and inflammation.

Introducción: Según el Ministerio de Salud las muertes por cáncer constituyen un cuarto del total de las defunciones registradas en Uruguay cada año. Objetivo: Conocer el perfíl epidemiológico de los pacientes diagnosticados de cáncer asistidos en el Hospital Departamental de Soriano. Material y métodos: Estudio observacional, retrospectivo y descriptivo que incluyó a los pacientes diagnosticados de cáncer asistidos en el Hospital Departamental de Soriano durante el 2022. Se mantuvo el anonimato de los pacientes en el análisis estadístico y se contó con la aprobación del Comité de Ética del Hospital de Clínicas. Resultados: Se incluyeron 113 pacientes nuevos; 53.1% fueron hombres, siendo la mediana de edad al diagnóstico de 69 años. Los 4 tumores más frecuentes para ambos sexos reunidos fueron: mama, próstata, pulmón y colo-recto; la distribución por estadio fue la siguiente: E IV 48.6% pacientes; EIII 22.5%; EII 26.5%; y EI 2.6%. En el 79.6% de las pacientes se contaba con la confirmación del diagnóstico mediante anatomía patológica. El tiempo entre el diagnóstico y el primer tratamiento oncológico fue ≤ 3 meses para el 88.2% de los pacientes. El total de los pacientes con EIV fueron contactados con la Unidad de Cuidados Paliativos. Únicamente el 15% de los casos fueron discutidos en Comité de Tumores. Conclusiones: Los datos analizados permitieron caracterizar el perfil epidemiológico del cáncer de los pacientes procedente de Soriano asistidos en el ámbito público y pueden contribuir a la implementación de políticas públicas orientadas a la prevención y por ende a la mejora en la asistencia pacientes asistidos.

Introduction: According to the Ministry of Health, cancer deaths constitute a quarter of the total deaths registered in Uruguay each year. Objective: To identify the epidemiological profile of patients diagnosed with cancer treated at the Departmental Hospital of Soriano. Materials and Methods: An observational, retrospective and descriptive study that included patients diagnosed with cancer attended at the Departmental Hospital of Soriano during 2022. The anonymity of the patients was maintained in the statistical analysis and approval was obtained from the Ethics Committee of the Hospital de Clínicas. Results: A total of 113 new patients were included; 53.1% were men, with a median age at diagnosis of 69 years old. The four most frequent tumors for both sexes were: breast, prostate, lung and colorectal; the distribution by stage was as follows: Stage IV 48.6% patients; Stage III 22.5%; Stage II 26.5%; and Stage I 2.6%. In 79.6% of the patients the diagnosis was confirmed by pathological anatomy. The time between diagnosis and first oncological treatment was ≤ 3 months for 88.2% of patients. The total number of patients with Stage IV were contacted by the Palliative Care Unit. Only 15% of the cases were discussed in the Tumor Committee. Conclusions: The data analyzed made it possible to characterize the epidemiological profile of cancer in patients from Soriano assisted in the public sector and may contribute to the implementation of public policies aimed at prevention and, therefore, at improving patient care.
