Osteosarcoma: fisiopatología, diagnóstico y tratamiento
Osteosarcoma is a rare malignant tumor that affects the bone. It has mesenchymal origin, and its incidence is higher during childhood and adolescence. In most cases, it develops in the metaphysis of long bones and clinically manifests with episodes of bone pain that may be accompanied by constitutional symptoms. It can be classified according to its grade, location and histological pattern; high-grade OS accounts for 90% of all cases and presents accelerated growth and grater aggressiveness. A bone biopsy is necessary to make a definitive diagnosis. Its definitive treatment includes surgery along with neoadjuvant and adjuvant chemotherapy, using the MAP regimen, which combines three chemotherapeutic agents and has proven to be the most effective, with an overall survival increase from 20% to 70%. Despite the efforts of the scientific community to develop new therapies that offer a better response, none of these has shown better results yet.El osteosarcoma (OS) es un tumor maligno infrecuente que afecta el hueso. Tiene origen mesenquimatoso y predomina en la infancia y adolescencia. Se localiza en la gran mayoría de los casos en metáfisis de huesos largos, y clínicamente debuta con episodios de dolor óseo que pueden estar o no acompañados de síntomas constitucionales. Se puede clasificar de acuerdo a su grado, localización y patrón histológico; el OS de alto grado abarca el 90% del total de casos y presenta crecimiento acelerado y mayor agresividad. Es necesaria una biopsia ósea para realizar el diagnóstico definitivo. Su tratamiento definitivo incluye la cirugía, en conjunto con quimioterapia neoadyuvante y adyuvante, mediante el esquema MAP, el cual combina tres quimioterapéuticos y ha demostrado ser el más eficaz, con un incremento de la sobrevida global de un 20% a un 70%. Pese al esfuerzo de la comunidad científica por desarrollar nuevas terapias que ofrezcan una mejor respuesta, ninguna de estas ha mostrado mejores resultados hasta el momento
COVID-19 pandemic control measures and their impact on university students and family members in a central region of Spain
Producción CientíficaThe first waves of the COVID-19 pandemic were times of great change in the lives of university students and their families in Spain. The aim of this study was to explore the psychosocial aspects and preventive measures carried out during the COVID-19 pandemic by students and family members of the nursing degree students of the University of Valladolid (Spain). The number of people surveyed was 877, by means of an ad hoc questionnaire. Relationships between variables were established by means of the Chi-square test and Student’s t-test. In addition, multivariate logistic regression was generated. The significance level used was 0.05. Students and family members maintained preventive measures= such as hand washing, correct use of masks =in closed places, avoiding crowds and maintaining social distance, but at low rates (close to 20% in all cases). Regarding psychosocial aspects, 41.07% of the participants suffered from anxiety and loneliness, while 5.2% needed to take drugs to reduce anxiety or sleep and 66.07% were dependent on technology. Suicidal behavior is related to stress, anxiety, loneliness, poor family relationships, psychotropic drug use and technology abuse. The pandemic has caused life changes in university students and their families at the psychosocial level, generating high figures of suicidal ideation regardless of age. Preventive measures adopted to control the pandemic have not been followed for the most part
Symptomatology Heterogeneity. Profiles Of Patients Diagnosed With Alzheimer's Type Dementia In Antioquia (Colombia)
Objetivo: Describir y contrastar la variabilidad sintomatológica de los casos con demencia tipo Alzheimer esporádico
(DTA+E) con los datos obtenidos de los casos con demencia tipo Alzheimer familiar precoz causado por la mutación E280A
del Neurobanco del Grupo de Neurociencias de Antioquia (GNA). Materiales y Método: Este estudio fue de tipo exploratoriodescriptivo y correlacional, se tomaron 83 casos de donantes con DTA almacenados en el Neurobanco del GNA. Estos casos se
dividen en dos grupos, i) un grupo definido genéticamente como portador de la mutación E280A en el gen de la Presenilina1;
y ii) otro grupo no portador de la mutación diagnosticado con Demencia Tipo Alzheimer Esporádico (DTA+E); se contrastaron
los marcadores y/o características neuropsiquiatricas, neuropsicológicas, neurológicas y neuropatológicas de ambos grupos.
Resultados: El síntoma que mostró mayores diferencias entre ambos grupos fue la repetidera (DTAF E280A fue de 1.2% y el
grupo de DTA+E fue 18.4%). Otros síntomas como la depresión o el tiempo de aparición de pérdida progresiva de memoria
no mostraron grandes diferencias entre grupos (DTAF E2080A=55.9%; DTA+E =53.1%) y (DTAF E2080A=55.9%; DTA+E
=53.1%). Los trastornos del lenguaje que se observaron con mayor frecuencia entre los donantes fueron la pérdida del lenguaje,
mutismo, anomia y afasia. El signo de mayor frecuencia en ambos grupos fue descontrol de esfínteres. La atrofia se registró
con mayor intensidad en los lóbulos temporales de los cerebros de los donantes con DTA +E (83.3%). Los pesos del cerebro y
del contenido de la fosa posterior, tienen una relación moderada, directamente proporcional y altamente significativa desde el
punto de vista estadístico. Conclusiones: Existen diferencias neuropatológicas entre DTA+E y E280A que pueden estar asociadas a la fisiopatología de la forma hereditaria de E280A.
Palabras claves: Demencia, AlzheimerObjective: To describe and contrast the symptomatic variability of cases with sporadic or non-sporadic Alzheimer's
dementia (DTA + E) with the data obtained from the cases with early familial Alzheimer's dementia caused by the E280A of
the Neurobank of the Neurosciences Group of Antioquia (GNA). Materials and Method: This study was of exploratory - descriptive and correlacional type, 83 donors' cases were taken with DTA stored in the Neurobank. These cases were divided in
two groups, i) a group defined genetically like E280A; and ii) another not carrying group of the mutation (DTA+E); the scoreboards and / or characteristics neuropsychiatric, neuropsychological, neurological and neuropathological of both groups were
confirmed. Results: The symptom that showed higher differences between both groups was iteration iteration (DTAF E280A
with 1.2% and 18.4% for the DTA+E group). Other symptoms as depression or the time of appearance of progressive loss of
memory did not show big differences among groups (DTAF E2080A=55.9%; DTA+E =53.1%) and (DTAF E2080A=55.9%;
DTA+E =53.1%). The language disorders that were observed with major frequency among the donors were the loss of the language, mutism, anomia and aphasia. The sign with higher frequency in both groups was lost of sphincter control. The atrophy
was with more intensity in the temporary lobes of the brains of the donors with DTA+E (83.3%). The weight of the brain and of
the posterior fosse content, they have a moderate, directly proportional and highly significant relation from the statistical point
of view. Conclusions: DTA +E has neuropathological differences with DTAF E280A that can be associated with the physiology
hereditary from of DTAF E280A.

Analyzing the Impact of COVID-19 Trauma on Developing Post-Traumatic Stress Disorder among Emergency Medical Workers in Spain
Producción CientíficaThe early stages of the COVID-19 pandemic presented the characteristics of a traumatic event that could trigger post-traumatic stress disorder. Emergency Medical Services workers are already a high-risk group due to their professional development. The research project aimed to analyse the impact of the COVID-19 pandemic on EMS professionals in terms of their mental health. For this purpose, we present a descriptive crosssectional study with survey methodology. A total of 317 EMS workers (doctors, nurses, and emergency medical technicians) were recruited voluntarily. Psychological distress, post-traumatic stress disorder, and insomnia were assessed. The instruments were the General Health Questionnaire-12 (GHQ-12), the Davidson Trauma Scale (DTS-8), and the Athens Insomnia Scale (AIS-8). We found that 36% of respondents had psychological distress, 30.9% potentially had PTSD, and 60.9% experienced insomnia. Years of work experience were found to be positively correlated, albeit with low effect, with the PTSD score (r = 0.133). Finally, it can be stated that the COVID-19 pandemic has been a traumatic event for EMS workers. The number of professionals presenting psychological distress, possible PTSD, or insomnia increased dramatically during the early phases of the pandemic. This study highlights the need for mental health disorder prevention programmes for EMS workers in the face of a pandemic.Departamento de Enfermería de la Universidad de Valladoli
Crustal velocity field in Baza and Galera faults: A new estimation from GPS position time series in 2009 - 2018 time span
The Baza and Galera faults are two active geologic structures located in the central area of the Betic Cordillera (Southern Spain). The goal of our research is to constrain the activity of this faults from high quality GPS measurements to obtain precise deformation rates. In 2008 a GPS survey – mode network was installed to monitor this area. In previous works, we presented a velocity field based on the analysis of some GPS campaigns. Here we show the new results computed from nine GPS campaigns in the timespan 2009-2018. The measurements were done in September 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2017 and 2018. The data process and analysis were performed in Precise Point Positioning by using GIPSYX 1.6 software. GIPSY is a GNSS-inferred positioning software developed by the Jet Propulsion Laboratory. Then, the new estimation of the crustal velocity field is computed from the IGb14 time series by SARI software. The model applied to the original time series, using weighted least squares, consists of an intercept, a site rate and an offset to account for an antenna change. The error term is composed of white noise and temporally correlated random error. The colored noise is described by a random-walk process. We have assumed a typical magnitude for this process of 1.0 mm/√yr. Finally, we discuss the implications of the new results for the tectonic setting and seismic hazard assessment of this key tectonic area of the Betic Cordillera.This work has been funded by Programa Operativo FEDER Andalucía 2014-2020 - call made by University of Jaen in 2018, Ref. 1263446, POAIUJA 2021/2022, CEACTEMA, and RNM148 and RNM282 research groups of Junta de Andalucía
How does neighbourhood socio-economic status affect the interrelationships between functioning dimensions in first episode of psychosis? A network analysis approach
The links between psychosis and socio-economic disadvantage have been widely studied. No previous study has analysed the interrelationships and mutual influences between functioning dimensions in first episode of psychosis (FEP) according to their neighbourhood household income, using a multidimensional and transdiagnostic perspective. 170 patients and 129 controls, participants in an observational study (AGES-CM), comprised the study sample. The WHO Disability Assessment Schedule (WHODAS 2.0) was used to assess functioning, whereas participants' postcodes were used to obtain the average household income for each neighbourhood, collected by the Spanish National Statistics Institute (INE). Network analyses were conducted with the aim of defining the interrelationships between the different dimensions of functioning according to the neighbourhood household income. Our results show that lower neighbourhood socioeconomic level is associated with lower functioning in patients with FEP. Moreover, our findings suggest that “household responsibilities” plays a central role in the disability of patients who live in low-income neighbourhoods, whereas “dealing with strangers” is the most important node in the network of patients who live in high-income neighbourhoods. These results could help to personalize treatments, by allowing the identification of potential functioning areas to be prioritized in the treatment of FEP according to the patient's neighbourhood characteristic
A neurodegenerative disease landscape of rare mutations in Colombia due to founder effects
Background
The Colombian population, as well as those in other Latin American regions, arose from a recent tri-continental admixture among Native Americans, Spanish invaders, and enslaved Africans, all of whom passed through a population bottleneck due to widespread infectious diseases that left small isolated local settlements. As a result, the current population reflects multiple founder effects derived from diverse ancestries.
Methods
We characterized the role of admixture and founder effects on the origination of the mutational landscape that led to neurodegenerative disorders under these historical circumstances. Genomes from 900 Colombian individuals with Alzheimer’s disease (AD) [n = 376], frontotemporal lobar degeneration-motor neuron disease continuum (FTLD-MND) [n = 197], early-onset dementia not otherwise specified (EOD) [n = 73], and healthy participants [n = 254] were analyzed. We examined their global and local ancestry proportions and screened this cohort for deleterious variants in disease-causing and risk-conferring genes.
Results
We identified 21 pathogenic variants in AD-FTLD related genes, and PSEN1 harbored the majority (11 pathogenic variants). Variants were identified from all three continental ancestries. TREM2 heterozygous and homozygous variants were the most common among AD risk genes (102 carriers), a point of interest because the disease risk conferred by these variants differed according to ancestry. Several gene variants that have a known association with MND in European populations had FTLD phenotypes on a Native American haplotype. Consistent with founder effects, identity by descent among carriers of the same variant was frequent.
Conclusions
Colombian demography with multiple mini-bottlenecks probably enhanced the detection of founder events and left a proportionally higher frequency of rare variants derived from the ancestral populations. These findings demonstrate the role of genomically defined ancestry in phenotypic disease expression, a phenotypic range of different rare mutations in the same gene, and further emphasize the importance of inclusiveness in genetic studies.Q2Q2Antecedentes
La población colombiana, así como la de otras regiones latinoamericanas, surgió de una mezcla tricontinental reciente entre los nativos americanos, los invasores españoles y los africanos esclavizados, todos los cuales pasaron por un cuello de botella poblacional debido a enfermedades infecciosas generalizadas que dejaron a pequeños aislados. asentamientos locales. Como resultado, la población actual refleja múltiples efectos fundadores derivados de diversas ascendencias.
Métodos
Caracterizamos el papel de la mezcla y los efectos fundadores en el origen del paisaje mutacional que condujo a trastornos neurodegenerativos en estas circunstancias históricas. Genomas de 900 individuos colombianos con enfermedad de Alzheimer (EA) [n = 376], continuo degeneración lobar frontotemporal-enfermedad de la motoneurona (FTLD-MND) [n = 197], demencia de inicio temprano no especificada (EOD) [n = 73 ], y participantes sanos [n = 254] fueron analizados. Examinamos sus proporciones de ascendencia global y local y examinamos esta cohorte en busca de variantes nocivas en los genes que causan enfermedades y confieren riesgos.
Resultados
Identificamos 21 variantes patogénicas en genes relacionados con AD-FTLD, y PSEN1 albergaba la mayoría (11 variantes patogénicas). Se identificaron variantes de las tres ascendencias continentales. Las variantes heterocigotas y homocigotas de TREM2 fueron las más comunes entre los genes de riesgo de EA (102 portadores), un punto de interés porque el riesgo de enfermedad conferido por estas variantes difería según la ascendencia. Varias variantes genéticas que tienen una asociación conocida con MND en poblaciones europeas tenían fenotipos FTLD en un haplotipo nativo americano. De acuerdo con los efectos del fundador, la identidad por descendencia entre portadores de la misma variante fue frecuente.
Conclusiones
La demografía colombiana con múltiples mini-cuellos de botella probablemente mejoró la detección de eventos fundadores y dejó una frecuencia proporcionalmente más alta de variantes raras derivadas de las poblaciones ancestrales. Estos hallazgos demuestran el papel de la ascendencia definida genómicamente en la expresión fenotípica de la enfermedad, un rango fenotípico de diferentes mutaciones raras en el mismo gen, y enfatizan aún más la importancia de la inclusión en los estudios genéticos.https://orcid.org/0000-0001-6529-7077https://scholar.google.com/citations?hl=es&user=kaGongoAAAAJ&view_op=list_works&sortby=pubdatehttps://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000055000&lang=esRevista Internacional - Indexad
Effectiveness and Safety of the Sequential Use of a Second and Third Anti-TNF Agent in Patients With Inflammatory Bowel Disease: Results From the Eneida Registry
Background: The effectiveness of the switch to another anti-tumor necrosis factor (anti-TNF) agent is not known. The aim of this study was to analyze the effectiveness and safety of treatment with a second and third anti-TNF drug after intolerance to or failure of a previous anti-TNF agent in inflammatory bowel disease (IBD) patients. Methods: We included patients diagnosed with IBD from the ENEIDA registry who received another anti-TNF after intolerance to or failure of a prior anti-TNF agent. Results: A total of 1122 patients were included. In the short term, remission was achieved in 55% of the patients with the second anti-TNF. The incidence of loss of response was 19% per patient-year with the second anti-TNF. Combination therapy (hazard ratio [HR], 2.4; 95% confidence interval [CI], 1.8-3; P < 0.0001) and ulcerative colitis vs Crohn's disease (HR, 1.6; 95% CI, 1.1-2.1; P = 0.005) were associated with a higher probability of loss of response. Fifteen percent of the patients had adverse events, and 10% had to discontinue the second anti-TNF. Of the 71 patients who received a third anti-TNF, 55% achieved remission. The incidence of loss of response was 22% per patient-year with a third anti-TNF. Adverse events occurred in 7 patients (11%), but only 1 stopped the drug. Conclusions: Approximately half of the patients who received a second anti-TNF achieved remission; nevertheless, a significant proportion of them subsequently lost response. Combination therapy and type of IBD were associated with loss of response. Remission was achieved in almost 50% of patients who received a third anti-TNF; nevertheless, a significant proportion of them subsequently lost response
