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.

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.

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.

Diffuse Large B-Cell Lymphoma in Chile: The Impact of Combined CHOP Plus Rituximab in the Public Health System.

PURPOSE: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma subtype. The purpose of this study was to evaluate the clinical features, prognostic factors, and results of DLBCL that was treated in the cancer centers of the public health system in Chile and compare cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). PATIENTS AND METHODS: Patients age > 15 years who were treated in 18 cancer centers in the country between 2001 and 2017 were included. The Kaplan-Meier method was used to calculate overall survival (OS), and Cox proportional hazard regression modeling was used to evaluate the effect of the addition of rituximab to CHOP on OS. RESULTS: A total of 1,807 patients were evaluated. The median age at diagnosis was 62 (range, 15-95) years, with a female predominance (53%). Half of the patients were age ≥ 60 years. Serology for HIV infection was positive in 5% of cases (96 cases). International Prognostic Index scores were available for 90% of patients, of which 45% had low-risk, 25% low-intermediate-risk, 18% high-intermediate-risk, and 11% high-risk scores. CHOP was administered to 986 patients (55%; median follow-up, 13.2 years) and R-CHOP to 821 patients (45%; median follow-up, 8.4 years). R-CHOP was associated with superior OS compared with CHOP (5-year 66% v 48%, and 10-year 53% v 35%; P < .001). CONCLUSION: Rituximab improved the survival of patients with DLBCL diagnosed and treated in Chile. The benefit was sustained over time, with curative rates of > 50%. This intervention shows that the inclusion of this biological drug justified the expenses incurred by the Ministry of Health in the National Lymphoma Protocols in Chile.

Overall survival in Chilean patients with lymphoma and human immunodeficiency virus: A retrospective cohort study

ABSTRACT Introduction: People living with human immunodeficiency virus (PLWH) still face high morbidity and mortality resulting from lymphoma. Aim: To describe a population of PLWH and lymphoma in a Chilean public hospital and compare the overall survival (OS) with a previously reported cohort from the same institution. Methods: Retrospective single-center cohort study. All the patients diagnosed between 2010 and 2017 were included. Demographic and clinical variables were obtained from medical records. The overall survival (OS) was estimated in treated patients from diagnosis until death or October 2020. The OS was then compared with a cohort of patients diagnosed between 1992 and 2008. Main Results: Eighty-four patients were included. The most common histological types were Burkitt's lymphoma (BL), diffuse large B-cell lymphoma (DLBCL), Hodgkin's lymphoma (HL) and plasmablastic lymphoma (PBL) at 31%, 27%, 21% and 14%, respectively. The three-year OS for the whole cohort of BL, DLBCL, HL and PBL was 58.9%, 65.2%, 47.4%, 76.4% and 50%, respectively. Compared to the cohort of 1992 to 2008, a global increase in the OS was found after excluding HL and adjusting for age and clinical stage (HR 0.38, p = 0.002). However, when the main types were analyzed individually, the increase in the OS was statistically significant only in DLBCL (HR 0.29, p = 0.007). Most patients with DLBCL received CHOP chemotherapy, as in the previous cohort. Conclusion: The OS has improved in this population, despite no major changes in chemotherapy regimens, mainly due to the universal access to antiretroviral therapy.

Characteristics and clinical outcomes of patients with ALK-positive anaplastic large cell lymphoma: Report from the prospective international T-cell lymphoma project.

The T-cell Lymphoma Project is an international registry prospective study that enrolled patients with newly diagnosed peripheral T-cell and NK-cell lymphomas (PTCL). The main objective was to define the clinical features and outcomes, establishing a robust benchmark for future clinical trials. Seventy-four institutions from 14 countries in North America, South America, Europe, and Asia collected data on patients diagnosed and treated at their respective centers between September 2006 and February 2018. Among 1553 PTCL patients, 131 (8.4% of the total cohort) were confirmed to have anaplastic large cell lymphoma - kinase positive (ALCL, ALK+). The median age of the patients was 39 years (18-84). Sixty-five patients (66%) had advanced-stage disease, although majority (45 patients, 54%) had a low-risk International Prognostic Index (IPI) score (0-1). Of 97 patients treated with chemotherapy, 97% received anthracycline-containing regimens. The overall response rate was 81%, with 69 patients (70%) achieving complete remission. Estimated OS and PFS at 3 years were 77% (95% CI: 54%-99%) and 68% (95% CI: 46%-90%), respectively, and at 5 years were very similar, 77% of OS (95% CI: 62%-92%) and 64% of PFS (95% CI: 34%-94%). Multivariate analysis for PFS showed advanced stage (hazard ratios [HR]: 4.72, 95% CI: 1.43-23.9, p = 0.015), elevated lactate dehidrogenade (LDH) (HR 4.85; 95% CI: 1.73-13.60, p = 0.001), and Eastern Cooperative Oncology Group Performance Status scale (ECOG-PS) ≥2 (HR: 5.25; 95% CI: 1.68-16.4, p = 0.024). For OS, elevated LDH (HR: 3.77; 95% CI: 1.98-14.17, p = 0.014) and ECOG-PS ≥2 (HR: 4.59; 95% CI: 1.46-14.39, p = 0.004) were identified. In summary, although the outcome of ALK+ ALCL is superior to that of other PTCLs, it remains sufficiently favorable, given the young median age of the patients. Our results confirm the usefulness of both IPI and Prognostic Index for T-cell Lymphoma (PIT) in identifying groups of patients with different outcomes. Clinical Trials ID: NCT01142674.

The radiographic assessment of lung edema score of lung edema severity correlates with inflammatory parameters in patients with coronavirus disease 2019-Potential new admission biomarkers to predict coronavirus disease 2019 worsening.

Background: Coronavirus disease 2019 (COVID-19) has placed enormous pressure on intensive care units (ICUs) and on healthcare systems in general. A deeper understanding of the pathophysiology of the most severe forms of COVID-19 would help guide the development of more effective interventions. Herein, we characterized the inflammatory state of patients with COVID-19 of varying degrees of severity to identify admission biomarkers for predicting COVID-19 worsening. Design: Admission blood samples were obtained from 78 patients with COVID-19. Radiographic assessment of lung edema (RALE) scoring was calculated by imaging. Platelet and leukocyte counts were measured by flow cytometry, and plasma levels of C-reactive protein were assessed by immunoturbidimetry, and interleukin (IL)-8/CXCL8, IL-10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, and monocyte chemoattractant protein-1 (MCP-1/CCL2) levels by enzyme-linked immunosorbent assay (ELISA). Results: The RALE score correlated with several admission hemogram (platelets, neutrophils, and lymphocytes) and inflammatory (IL-8/CXCL8, MCP-1/CCL2, IL-10, and C-reactive protein) parameters. COVID-19 worsening, based on the need for oxygen (Δoxygen supply) during hospitalization, correlated negatively with admission lymphocyte counts but positively with neutrophil-to-lymphocyte ratio and with plasma levels of the inflammatory parameters correlating with RALE score. Conclusion: Our data indicate a correlation between the RALE score and Δoxygen supply and admission inflammatory status. The identification of a panel of biomarkers that reflect COVID severity might be useful to predict disease worsening during hospitalization and to guide clinical management of COVID-19-related complications. Finally, therapies targeting IL-8/CXCL8- or IL-10 activity may offer therapeutic approaches in COVID-19 treatment.

Directional DBS of the Fornix in Alzheimer's Disease Achieves Long-Term Benefits: A Case Report.

Background: Current treatments for Alzheimer's disease (AD) modulate global neurotransmission but are neither specific nor anatomically directed. Tailored stimulation of target nuclei will increase treatment efficacy while reducing side effects. We report the results of the first directional deep brain stimulation (dDBS) surgery and treatment of a patient with AD in an attempt to slow the progression of the disease in a woman with multi-domain, amnestic cognitive status. Methods: We aimed to assess the safety of dDBS in patients with AD using the fornix as stimulation target (primary objective) and the clinical impact of the stimulation (secondary objective). In a registered clinical trial, a female patient aged 81 years with a 2-year history of cognitive decline and diagnoses of AD underwent a bilateral dDBS surgery targeting the fornix. Stimulation parameters were set between 3.9 and 7.5 mA, 90 µs, 130 Hz for 24 months, controlling stimulation effects by 18F-fluoro-2-deoxy-D-glucose (18F-FDG) scans (baseline, 12 and 24 months), magnetoencephalography (MEG) and clinical/neuropsychological assessment (baseline, 6, 12, 18, and 24 months). Results: There were no important complications related to the procedure. In general terms, the patient showed cognitive fluctuations over the period, related to attention and executive function patterns, with no meaningful changes in any other cognitive functions, as is shown in the clinical dementia rating scale (CDR = 1) scores over the 24 months. Such stability in neuropsychological scores corresponds to the stability of the brain metabolic function, seen in PET scans. The MEG studies described low functional connectivity at baseline and a subsequent increase in the number of significant connections, mainly in the theta band, at 12 months. Conclusion: The dDBS stimulation in the fornix seems to be a safe treatment for patients in the first stage of AD.

Affectivity and physical habits in adolescents: A systematic review / Afectividad y hábitos físicos en adolescentes: una revisión sistemática

Introduction: Affectivity has a fundamental role in educational systems' training process. However, there are no updated studies that show the different socio-affective agents used in the creation of physical habits in the child and adolescent population in school systems. Objective: To review and analyze previously published research that studied the influence of affectivity on children and adolescents' physical habits in school systems. Materials and methods: A systematic review was conducted with articles published between 2010 and 2020, which connected affectivity and physical habits. The electronic search was performed through Web of Science, Scopus, and Scielo databases. All articles that studied the influence of affectivity on the population's physical habits were included. Results: Three studies that analyzed the influence of affectivity on children and adolescents' physical habits were found. Conclusions: At the end of the systematic review, it was demonstrated that there is a significant relationship between affectivity and the physical habits in child and adolescent populations. It was also possible to observe that this influence, positive or negative, determines the child and adolescent population's interest in physical activity and sports in adult life.

Introducción: La afectividad tiene un papel fundamental dentro del proceso de formación en los sistemas educativos. Sin embargo, no existen estudios actualizados que evidencien los diversos agentes socioafectivos utilizados en la creación de hábitos físicos en la población infantil y adolescente de los sistemas escolares. Objetivo: Analizar investigaciones previamente publicadas que estudiaron la influencia de la afectividad en los hábitos físicos de niños y adolescente de los sistemas escolares. Materiales y métodos: El estudio corresponde a una revisión sistemática. Se evaluaron artículos publicados entre 2010 y 2020 que relacionaron afectividad y hábitos físicos. La búsqueda electrónica se realizó a través de las bases Web of Science, Scopus y Scielo. Se incluyeron todos los artículos que utilizaron la afectividad sobre los hábitos físicos de la población. Resultados: Se encontraron tres artículos que utilizaron la afectividad sobre los hábitos físicos de niños y adolescentes. Conclusiones: Al término de la revisión sistemática, se demostró que existe una tremenda influencia entre la afectividad y los hábitos físicos de la población infantil y adolescente. También se pudo observar que esta influencia, positiva o negativa, condiciona el interés de la población infantil y juvenil por la actividad física y el deporte en la vida adulta.

Epidemiology of chronic lymphocytic leukemia in Chilean and Amerindian population in Chile.

The study aim was to analyze incidence and presentation features of chronic lymphocytic leukemia (CLL) in Chile, in Amerindian population and in non-Native. Between 2012 and 2019, 912 patients were diagnosed, and 13 (1.4%) were Amerindian. The estimated incidence in Chilean population was 1.17/100,000 person per year, while in Amerindian, 0.09/100,000 person per year. Median age was 73 years. At diagnosis, 48, 27, and 25%, had low (0), intermediate (I/II) and high-risk (III/IV) disease on Rai classification. Diagnostic immunophenotypic Matutes score was ≥4 in 90%. Median follow-up was 37 months (range 2-87). 5-year OS was 56%, with median overall survival (OS) not reached. It was worse in men, ≥65 years, high-risk and those with increased prolymphocytes (CLL/PL). This study shows low incidence and worse OS in Chilean CLL patients, compared to those from European countries, despite similar clinical features. It also demonstrates that CLL is very uncommon in Amerindian population.

Overall survival in Chilean patients with lymphoma and human immunodeficiency virus: A retrospective cohort study.

INTRODUCTION: People living with human immunodeficiency virus (PLWH) still face high morbidity and mortality resulting from lymphoma. AIM: To describe a population of PLWH and lymphoma in a Chilean public hospital and compare the overall survival (OS) with a previously reported cohort from the same institution. METHODS: Retrospective single-center cohort study. All the patients diagnosed between 2010 and 2017 were included. Demographic and clinical variables were obtained from medical records. The overall survival (OS) was estimated in treated patients from diagnosis until death or October 2020. The OS was then compared with a cohort of patients diagnosed between 1992 and 2008. MAIN RESULTS: Eighty-four patients were included. The most common histological types were Burkitt´s lymphoma (BL), diffuse large B-cell lymphoma (DLBCL), Hodgkin´s lymphoma (HL) and plasmablastic lymphoma (PBL) at 31%, 27%, 21% and 14%, respectively. The three-year OS for the whole cohort of BL, DLBCL, HL and PBL was 58.9%, 65.2%, 47.4%, 76.4% and 50%, respectively. Compared to the cohort of 1992 to 2008, a global increase in the OS was found after excluding HL and adjusting for age and clinical stage (HR 0.38, p = 0.002). However, when the main types were analyzed individually, the increase in the OS was statistically significant only in DLBCL (HR 0.29, p = 0.007). Most patients with DLBCL received CHOP chemotherapy, as in the previous cohort. CONCLUSION: The OS has improved in this population, despite no major changes in chemotherapy regimens, mainly due to the universal access to antiretroviral therapy.
