    Get PDF
    En la actualidad, la endocarditis infecciosa es una enfermedad poco frecuente, con una incidencia estimada entre 3,1 y 3,7 episodios cada 100.000 habitantes/año. Pese a los progresos en el tratamiento médico-quirúrgico, la mortalidad hospitalaria de los pacientes con endocarditis es alta. La endocarditis infecciosa es un proceso que se debe a una infección microbiana localizada en el endocardio. La zona afectada con más frecuencia es la superficie de las válvulas y, en la mayor parte de los casos, es de origen bacteriano. Un tipo de endocarditis es el denominado síndrome de Austrian, esta afección tiene un mecanismo diferente a otros tipos de endocarditis y destaca por la agresividad con la que se destruye la región valvular izquierda del corazón. El nombre que da título al caso se debe al médico que publicó la triada de neumonía, endocarditis y meningitis neumocócica. Se presenta el caso clínico de una mujer de 68 años diagnosticada de síndrome de Austrian que ingresó en una Unidad de Cuidados Críticos Cardiológicos con gran inestabilidad hemodinámica, sedoanalgesiada y en tratamiento con ventilación mecánica por una insuficiencia respiratoria. Dada la gravedad del caso está justificado establecer un plan de cuidados basado en el modelo bifocal de Carpenito para resolver las necesidades de salud reales y potenciales en un paciente diagnosticado de síndrome de Austrian, apoyándonos en la taxonomía North American Nursing Diagnosis Association, así como en la Nursing Outcomes Classification y Nursing Interventions Classification para delimitar objetivos e intervenciones enfermeras, respectivamente.Infective endocarditis is currently an uncommon disease, with an estimated incidence of between 3.1 and 3.7 episodes per 100,000 inhabitants/year. Despite the progress in medical-surgical treatment, hospital mortality of patients with endocarditis is high. Infective endocarditis is a process that is due to a microbial infection localized in the endocardium. The area most often affected is the surface of the valves and in most cases it has a bacterial origin. A type of endocarditis is the so-called Austrian syndrome; this condition has a different mechanism from other types of endocarditis and stands out for the aggressiveness with which the left valvular region of the heart is destroyed. The name that entitles the case is due to the doctor who published the triad of pneumonia, endocarditis and pneumococcal meningitis. We present the case of a 68-year-old woman, diagnosed with Austrian syndrome, who was admitted into a Cardiac Intensive Care Unit with a serious hemodynamic instability, under sedation and analgesia and on treatment with mechanical ventilation due to respiratory failure. Considering the seriousness of the case, there is a justification for establishing a care plan based on Carpenito?s bifocal model so as to meet the real and potential health needs in a patient diagnosed with Austrian Syndrome, relying on the North American Nursing Diagnosis Association taxonomy, as well as on the Nursing Outcomes Classification and the Nursing Interventions Classification, in order to define objectives and nursing interventions, respectively

    Student Perceptions of the Resilience in a Confinement Due to COVID-19 in University of A Coruña: A Qualitative Research

    Get PDF
    [Abstract] The home confinement caused by COVID-19 has caused university students to express feelings, negative experiences, and concerns about the confinement situation they were experiencing. This prompted the development of research on resilience, which shows that it is closely related to well-being. The general objective is to determine if resilience acts as a guarantor of personal growth and, therefore, of the self-perception of well-being. The research is developed with qualitative methodology and is framed in the interpretative phenomenological analysis approach and is framed in the hermeneutic-dialectical method. The selection of participants was carried out through an intentional sampling, by non-random methods, among university students. Fifty-two students participated, 41 are women (78.84%) and 11 men (21.15%), with an average age of 20.7 years. The information was collected through a diary card in which they had to collect their experiences and prepare a short speech identifying three temporal moments of confinement: beginning, during, and end. The information was collected between 16 April and 15 May 2020. An inductive analysis was carried out, and the emerging categories were defined: personal growth, resilience, and well-being. Personal growth materializes through three subcategories: personal changes, interpersonal changes, and changes in the philosophy of life. The university students showed that the vital transformation related with resilience acts as a guarantor of personal growth and self-perception of well-being. A voluntary, conscious, and intelligent evolution of people is detected, and personal changes, interpersonal changes, and changes in the philosophy of life are identified as factors of personal growth

    Background: to evaluate whether the addition of bevacizumab (BVZ) to capecitabine-based chemoradiotherapy in the preoperative treatment of locally advanced rectal cancer (LARC) improves efficacy measured by the pathological complete response (pCR) rate. Methods: a phase II two-step design was performed. Patients received four cycles of therapy consisting of: BVZ 10 mg/kg in first infusion on day 1 and 5 mg/kg on days 15, 29, 43, capecitabine 1800 mg/m2/day 5 days per week during radiotherapy, which consisted of external-beam irradiation (45 Gy in 1.8 Gy dose per session over 5 sessions/week for 5 weeks). Six to eight weeks after completion of all therapies surgery was undergone. To profile the biological behaviour during BVZ treatment we measured molecular biomarkers before treatment, during BVZ monotherapy, and during and after combination therapy. Microvessel density (MVD) was measured after surgery. Results: forty-three patients were assessed and 41 were included in the study. Three patients achieved a pathological complete response (3/40: 7.5%) and 27 (67.5%) had a pathological partial response, (overall pathological response rate of 75%). A further 8 patients (20%) had stable disease, giving a disease control rate of 95%. Downstaging occurred in 31 (31/40: 77.5%) of the patients evaluated. This treatment resulted in an actuarial 4-year disease-free and overall survival of 85.4 and 92.7% respectively. BVZ with chemoradiotherapy showed acceptable toxicity. No correlations were observed between biomarker results and efficacy variables. Conclusion: BVZ with capecitabine and radiotherapy seem safe and active and produce promising survival results in LARC

    The efficacy of licensed direct-acting antiviral (DAA) regimens is assumed to be the same for hepatitis C virus (HCV)–monoinfected patients (HCV-Mono) and HIV/HCV-coinfected patients (HCV-Co). However, the high sustained viral response (SVR) rates of DAA regimens and the small number of HIV-infected patients included in registration trials have made it difficult to identify predictors of treatment failure, including the presence of HIV. Methods. We compared treatment outcomes for ledipasvir/sofosbuvir (LDV/SOF) against HCV G1 in treatment-naïve HCV-Mono and HCV-Co without cirrhosis in a prospective registry of individuals receiving DAAs for HCV. Results. Up to September 2017, a total of 17 269 patients were registered, and 1358 patients (1055 HCV-Mono/303 HCV-Co) met the inclusion criteria. Significant differences between HCV-Mono and HCV-Co were observed for age, gender, and G1 subtype distribution. Among HCV-Co, 99.0% were receiving antiretroviral therapy. SVR rates for LDV/SOF at 8 weeks did not differ significantly between HCV-Mono and HCV-Co (96.9% vs 94.0%; P = .199). However, the SVR rate for LDV/SOF at 12 weeks was significantly higher for HCV-Mono than HCV-Co (97.2% vs 91.8%; P = .001). A multivariable logistic regression model including age, sex, liver stiffness, G1 subtype, HCV-RNA, HIV, and treatment duration showed the factors associated with treatment failure to be male sex (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.27–4.91; P = .008) and HIV infection (aOR, 2.23; 95% CI, 1.13–4.38; P = .020). Conclusions. The results of this large prospective study analyzing outcomes for LDV/SOF against HCV G1 in treatment-naïve noncirrhotic patients suggest that HIV infection is a predictor of treatment failure in patients with chronic hepatitis C.This work was supported by the Spanish AIDS Research Network (RD16/0025/0017), which is included in the Spanish I+D+I Plan and is co-financed by ISCIII-Subdirección General de Evaluacion and European Funding for Regional Development (FEDER), and the Fondo de Investigación de Sanidad en España (FIS)/Instituto de Salud Carlos III (Spanish Health Research Funds; PI17/00657)

    The New Antitumor Drug ABTL0812 Inhibits the Akt/mTORC1 Axis by Upregulating Tribbles-3 Pseudokinase

    Purpose: ABTL0812 is a novel first-in-class, small molecule which showed antiproliferative effect on tumor cells in phenotypic assays. Here we describe the mechanism of action of this antitumor drug, which is currently in clinical development. Experimental design: We investigated the effect of ABTL0812 on cancer cell death, proliferation, and modulation of intracellular signaling pathways, using human lung (A549) and pancreatic (MiaPaCa-2) cancer cells and tumor xenografts. To identify cellular targets, we performed in silico high-throughput screening comparing ABTL0812 chemical structure against ChEMBL15 database. Results: ABTL0812 inhibited Akt/mTORC1 axis, resulting in impaired cancer cell proliferation and autophagy-mediated cell death. In silico screening led us to identify PPARs, PPARα and PPARγ as the cellular targets of ABTL0812. We showed that ABTL0812 activates both PPAR receptors, resulting in upregulation of Tribbles-3 pseudokinase (TRIB3) gene expression. Upregulated TRIB3 binds cellular Akt, preventing its activation by upstream kinases, resulting in Akt inhibition and suppression of the Akt/mTORC1 axis. Pharmacologic inhibition of PPARα/γ or TRIB3 silencing prevented ABTL0812-induced cell death. ABTL0812 treatment induced Akt inhibition in cancer cells, tumor xenografts, and peripheral blood mononuclear cells from patients enrolled in phase I/Ib first-in-human clinical trial. Conclusions: ABTL0812 has a unique and novel mechanism of action, that defines a new and drugable cellular route that links PPARs to Akt/mTORC1 axis, where TRIB3 pseudokinase plays a central role. Activation of this route (PPARα/γ-TRIB3-Akt-mTORC1) leads to autophagy-mediated cancer cell death. Given the low toxicity and high tolerability of ABTL0812, our results support further development of ABTL0812 as a promising anticancer therapy

    Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population.This work was supported in part by the Spanish AIDS Research Network (RD16/0025/0017, RD16/0025/0018), which is included in the Spanish I+D+I Plan and is co-funded by the ISCIII-Subdirección General de Evaluación and European Funding for Regional Development (FEDER).

    Background: We assessed the prevalence of antibodies against hepatitis C virus (HCV-Abs) and active HCV infection in patients infected with human immunodeficiency virus (HIV) in Spain in 2016 and compared the results with those of similar studies performed in 2002, 2009, and 2015. Methods: The study was performed in 43 centers during October-November 2016. The sample was estimated for an accuracy of 2% and selected by proportional allocation and simple random sampling. During 2016, criteria for therapy based on direct-acting antiviral agents (DAA) were at least significant liver fibrosis, severe extrahepatic manifestations of HCV, and high risk of HCV transmissibility. Results: The reference population and the sample size were 38904 and 1588 patients, respectively. The prevalence of HCV-Abs in 2002, 2009, 2015, and 2016 was 60.8%, 50.2%, 37.7%, and 34.6%, respectively (P trend <.001, from 2002 to 2015). The prevalence of active HCV in 2002, 2009, 2015, and 2016 was 54.0%, 34.0%, 22.1%, and 11.7%, respectively (P trend <.001). The anti-HCV treatment uptake in 2002, 2009, 2015, and 2016 was 23.0%, 48.0%, 59.3%, and 74.7%, respectively (P trend <.001). In 2016, HCV-related cirrhosis was present in 7.6% of all HIV-infected individuals, 15.0% of patients with active HCV, and 31.5% of patients who cleared HCV after anti-HCV therapy. Conclusions: Our findings suggest that with universal access to DAA-based therapy and continued efforts in prevention and screening, it will be possible to eliminate active HCV among HIV-infected individuals in Spain in the short term. However, the burden of HCV-related cirrhosis will continue to be significant among HIV-infected individuals.This work was funded by grant Ref. no.

    Vigilancia epidemiológica de parasitosis zoonóticas en un área centinela desde la perspectiva de Una Salud

    Get PDF
    El abordaje de las enfermedades zoonóticas debe realizarse desde un enfoque multisectorial. Desde el concepto de Una Salud, las acciones realizadas por un solo sector no resultan eficaces para controlar este tipo de infecciones. En ese sentido, los distintos agentes de enfermedades transmisibles zoonóticas, afectan tanto a animales como a humanos y habitualmente el ecosistema actúa como reservorio o transmisor directo o indirecto, en la interfaz hombre-animal-ambiente. Los caninos pueden diseminar con sus heces enteroparásitos transmisibles a humanos y como animales centinela, pueden utilizarse para realizar vigilancia de la circulación de patógenos. Algunas helmintiasis, varias protozoosis y el alga parásita Blastocystis sp., son comunes en caninos y humanos. Nematodes del género Toxocara spp., enteroparásito de animales, ocasionan en personas toxocarosis, enfermedad de elevada seroprevalencia en la ciudad de La Plata y otras regiones. Sus formas neurológica y ocular tienen generalmente serias consecuencias. Su presencia en humanos se ve influenciada favorablemente por el lugar de residencia y su tejido suburbano. Giardia lamblia, enteroparásito zoonótico, ocasiona síndrome de malabsorción y modificación de moléculas de fármacos, también se correlaciona giardiasis con enfermedad de Whipple y otros disturbios gastroentéricos. El enfoque "Una salud" tiene en su estructura elementos esenciales, ellos son voluntad política (compromiso con las normas internacionales y los Objetivos de Desarrollo Sostenible), planes de financiación sostenibles; comunicación (entre sectores y disciplinas a nivel internacional, regional, nacional y subnacional). Los aprendizajes socialmente productivos y significativos “resignifica el papel social, cultural y económico social del conocimiento” y son aquellos “modifican a los sujetos enseñándoles a transformar su naturaleza y su cultura, enriqueciendo el capital cultural de la sociedad y de las comunidades” (Orozco B, 2009: 88). Los objetivos de este trabajo fueron: Realizar vigilancia y alertas tempranas en cuanto a parasitosis humanas animales y zoonóticas. Ejecutar acciones tendientes a su control. Implementar aprendizajes socialmente significativos.Facultad de Ciencias Veterinaria

    Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

    Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
