Hazard assessment of nanoplastics is driven by their surface-functionalization. Effects in human-derived primary endothelial cells.

During plastic waste degradation into micro/nanoplastics (MNPLs) their physicochemical characteristics including surface properties (charge, functionalization, biocorona, etc.) can change, potentially affecting their biological effects. This paper focuses on the surface functionalization of MNPLs to determine if it has a direct impact on the toxicokinetic and toxicodynamic interactions in human umbilical vein endothelial cells (HUVECs), at different exposure times. Pristine polystyrene nanoplastics (PS-NPLs), as well as their carboxylated (PS-C-NPLs) and aminated (PS-A-NPLs) forms, all around 50 nm, were used in a wide battery of toxicological assays. These assays encompassed evaluations on cell viability, cell internalization, induction of intracellular reactive oxygen species (iROS), and genotoxicity. The experiments were conducted at a concentration of 100 µg/mL, chosen to ensure a high internalization rate across all treatments while maintaining a sub-toxic concentration. Our results show that all PS-NPLs are internalized by HUVECs, but the internalization dynamic depends on the particle's functionalization. PS-NPLs and PS-C-NPLs internalization modify the morphology of the cell increasing its inner complexity/granularity. Regarding cell toxicity, only PS-A-NPLs reduced cell viability. Intracellular ROS was induced by the three different PS-NPLs but at different time points. Genotoxic damage was induced by the three PS-NPLs at short exposures (2 h), but not for PS-C-NPLs at 24 h. Overall, this study suggests that the toxicological effects of PSNPLs on HUVEC cells are surface-dependent, highlighting the relevance of using human-derived primary cells as a target.

[Consultations to Emergency Departments for acute psychosis associated with illycit drugs use in Spain (REDUrHE Registry)]. / Consultas a Urgencias hospitalarias por psicosis aguda asociada al consumo de drogas ilegales en España (Registro REDUrHE).

OBJECTIVE: Mental health problems are increasing in Spain, and those related to drug use are a preventable aspect of public health. In Spain there are few studies on the incidence and characteristics of acute psychosis due to illegal drug use, especially at national and multicenter level, reason that motivated this paper. METHODS: A prospective multicentre study was carried out in eleven hospital Emergency Departments in Spain, lasting twenty-four months (REDUrHE Registry). Patients with acute psychosis were compared with those with organic pathology, analysing demographic aspects, drugs involved, associated clinical manifestations and evolution Quantitative variables were compared using Student's t-test and qualitative variables were compared using the chi-squared test (or Fisher's exact test as appropriate) and the magnitude of the association with the presence of psychosis using logistic regression. A p-value of less than 0.05 was considered statistically significant or if the 95%CI of the OR excluded the value 1. RESULTS: Of the 4,487 patients in the registry, 9.5% presented acute psychosis, with a median age of thirty-two years and 79% male. The main clinical features were agitation (53%, p=0.001), hallucinations (43.2%, p=0.001) and anxiety (40%, p=0.00). Psychosis was more frequent with cannabis (57.7%), cocaine (42%) and amphetamines and derivatives (26.4%), although in the analysis adjusted for co-drug use (39.5%), or in association with ethyl alcohol (57.7%), it was only statistically significant for cannabis (p=0.0). Patients with psychosis required more hospital admissions (38.1% vs. 10%, p=0.001), mainly in psychiatric units (34.1% vs. 4.2%, p=0.001), with hardly any intensive care unit admissions (0.4% vs. 2.1%, p=0.01). ED stay was high (29.3±73.8 hours vs 10.5±58.8 hours, p=0.001). CONCLUSIONS: In Spain, cannabis is the drug most associated with psychosis. This clinical condition produces more hospital admissions, although with a low risk at an organic level.

OBJETIVO: Los problemas de salud mental van en aumento en España, siendo los relacionados con el consumo de drogas una faceta prevenible en el ámbito de la Salud Pública. En España existen pocos estudios sobre la incidencia y características de la psicosis aguda por consumo de drogas ilegales, sobre todo de ámbito nacional y multicéntrico, razón que motivó este trabajo. METODOS: Se realizó un estudio multicéntrico prospectivo, de veinticuatro meses de duración, en once servicios de Urgencias hospitalarias de España (Registro REDUrHE). Se compararon los pacientes con psicosis aguda respecto a los que presentaban patología orgánica, analizando aspectos demográficos, drogas involucradas, clínica asociada y evolución. Las variables cuantitativas se compararon mediante la t de Student y cualitativas con la prueba ji al cuadrado (o el test exacto de Fisher según procediera) y la magnitud de la asociación con la presencia de psicosis mediante regresión logística. Se consideró estadísticamente significativo un valor de p menor de 0,05 o si el IC95% de la OR excluía el valor 1. RESULTADOS: De los 4.487 pacientes del registro, el 9,5% presentó psicosis aguda, con una mediana de edad de treinta y dos años y un 79% de varones. La clínica principal consistió en agitación (53%, p=0,001), alucinaciones (43,2%, p=0,001) y ansiedad (40%, p=0,00). La psicosis fue más frecuente con el consumo de cannabis (57,7%), de cocaína (42%) y de anfetaminas y derivados (26,4%), aunque en el análisis ajustado por coingesta de varias drogas (39,5%), o asociado a alcohol etílico (57,7%), sólo resultó estadísticamente significativo para el cannabis (p=0,0). Los pacientes con psicosis precisaron más ingreso hospitalario (38,1% frente a 10%, p=0,001), fundamentalmente en Unidades de psiquiatría (34,1% frente a 4,2%, p=0,001), sin apenas ingresar en unidades de cuidados intensivos (0,4% frente a 2,1%, p=0,01). La estancia en Urgencias fue más elevada (29,3±73,8 horas frente a 10,5±58,8 horas, p=0,001). CONCLUSIONES: En España, el cannabis es la droga que se relaciona en mayor medida con los casos de psicosis atendidas en Urgencias hospitalarias. Ésta clínica produce más ingresos hospitalarios, aunque con bajo riesgo a nivel orgánico.

Objectives: To describe the sociodemographic characteristics, drug use patterns, and the severity of drug overdoses treated in hospital emergency departments according to the registry of the Spanish Research Network on Drugs in Hospital Emergency Departments (REDUrHE project), and to identify differences between patterns on weekdays and weekends/national holidays. Material and methods: Eleven hospitals participated in the REDUrHE project, studying consecutive patients with symptoms of drug overdose over a 24-month period. The drugs implicated were extracted from clinical records or toxicology reports. An overdose was considered severe if management required intubation, cardiopulmonary resuscitation, or admission to the intensive care unit, or if in-hospital death occurred (composite event). Each of these variables was also analyzed by itself. (AU)

Spanish Research Network on Drugs in Hospital Emergency Departments - the REDUrHE registry: general analysis and comparisons between weekend and weekday poisonings. / Red de Estudio de Drogas en Urgencias Hospitalarias en España (Registro REDUrHE): análisis general y comparación según asistencia en día laborable o festivo.

OBJECTIVES: To describe the sociodemographic characteristics, drug use patterns, and the severity of drug overdoses treated in hospital emergency departments according to the registry of the Spanish Research Network on Drugs in Hospital Emergency Departments (REDUrHE project), and to identify differences between patterns on weekdays and weekends/national holidays. MATERIAL AND METHODS: Eleven hospitals participated in the REDUrHE project, studying consecutive patients with symptoms of drug overdose over a 24-month period. The drugs implicated were extracted from clinical records or toxicology reports. An overdose was considered severe if management required intubation, cardiopulmonary resuscitation, or admission to the intensive care unit, or if in-hospital death occurred (composite event). Each of these variables was also analyzed by itself. RESULTS: A total of 4526 patients were studied (2218 [49%] on weekends/holidays; 2308 [51%] on workdays). The mean (SD) age was 33 (11) years, and 75.5% were men. The most commonly used drugs were cocaine (47.8%), paciencannabis (44.4%), amphetamine derivatives (25.5%), benzodiazepines (8.8%), and opioids (7.3%). Patients treated on weekends/holidays were younger (32.1 vs 33.1 years on weekdays, P = .006), and they were more often taken to the hospital in an ambulance (60.5% vs 57.3%, P = .035). Hospitals in large cities (Barcelona and Madrid) saw more patients on weekends/holidays (55.8%). Major tourist destinations (the Balearic and Canary Islands) saw fewer patients on weekends/holidays (44.7%, P .001). Alcohol was ingested along with a drug by 58.2%; this combination was more common on weekends/holidays (in 63.3% vs 52.9% on weekdays, P .001), and 39.4% used more than 1 drug. Use of more than 1 drug was less common on weekends (in 37.6% vs 41.2%, P = .013). Opioid emergencies were also less frequent on weekends (6.0% vs 8.6%, P = .001), when gamma-hydroxybutyrate (GHB) overdoses were more common (5.8% vs 3.6%, P .001). Severity indicators were present (the composite event) more often on weekends (in 3.6% vs 2.2%, P = .006). Likewise, weekends saw more intubations (in 2.3% vs 1.0%, P = .001) and intensive care unit admissions (2.4% vs 1.6%, P = .047). Twelve patients (0.3%) died; mortality was similar on weekends (0.2%) and weekdays (0.3%) (P = .826). After adjusting for age, sex, combined use of alcohol, and type of drug, the risk of the severe-event composite was greater on weekends (odds ratio, 1.569; 95% CI, 1.088-2.263). CONCLUSION: Weekend and holiday emergencies due to drug overdoses are more frequent in large city hospitals. Weekend emergencies share certain distinctive characteristics: patients are younger, alcohol more often is ingested with drugs but multiple-drug combinations are less common, and GHB is used more often while opioids are used less often. Severe poisonings occur more often on weekends and holidays.

El indicador primario de gravedad fue el evento adverso combinado formado por intubación, parada cardiorrespiratoria, ingreso en cuidados intensivos o muerte intrahospitalaria y los indicadores secundarios cada uno de estos eventos adversos considerado individualmente. RESULTADOS: Se incluyeron 4.526 pacientes (festivo: 2.218, 49%; laborables: 2.308, 51%), con edad media de 33 años (DE 11) y 75,5% hombres. Las drogas más frecuentemente involucradas fueron cocaína (47,8%), cannabis (44,4%), derivados anfetamínicos (25,5%), benzodiacepinas (8,8%) y opiáceos (7,3%). Los pacientes atendidos en festivos eran más jóvenes (32,1 vs 33,1 años, p = 0,006) y más frecuentemente traídos al SUH en ambulancia (60,5% vs 57,3%, p = 0,035). Los SUH de grandes ciudades (Barcelona, Madrid) tuvieron la mayor afluencia en festivo (55,8%) y los de zonas de alto turismo lúdico (Baleares, Canarias) los de menor afluencia (44,7%; p 0,001). El 58,2% ingirió simultáneamente etanol (más en festivos, 63,3% vs 52,9%, p 0,001) y el 39,4% más de una droga (menos en festivos, 37,6% vs 41,2%, p = 0,013). En festivo, los opiáceos fueron menos frecuentes (6,0% vs 8,6%, p = 0,001) y el gamma- hidroxibutirato más (5,8% vs 3,6%, p 0,001). También en festivo, hubo más eventos combinados adversos (3,6% vs 2,2%; p = 0,006), más intubaciones (2,3% vs 1,0%, p = 0,001) y más ingresos en cuidados intensivos (2,4% vs 1,6%, p = 0,047). Fallecieron 12 pacientes (0,3%), sin diferencias entre grupos (0,2% vs 0,3%, p = 0,826). Al ajustar por edad, sexo, ingesta combinada de etanol y tipos de drogas implicadas, los pacientes atendidos en festivos tuvieron más riesgo de evento adverso combinado, con OR = 1,569 (IC 95% = 1,088-2,263). CONCLUSIONES: Las intoxicaciones por drogas atendidas en SUH en día festivo suceden con mayor frecuencia en grandes ciudades y presentan ciertas características distintivas (pacientes más jóvenes, más ingesta conjunta con etanol, menos combinación de drogas, más frecuente gamma-hidroxibutirato y menos frecuente piáceos). Durante los festivos, las intoxicaciones atendidas son de mayor gravedad.

Characteristics of COVID-19 in cancer patients: a cross-sectional study in Peru.

BACKGROUND: Cancer patients are at higher risk of infection and severity of Coronavirus Disease-19 (COVID-19). Management of patients infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is challenging due to the scarce scientific information and treatment guidelines. In this work, we present our Institutional experience with our first 100 patients with oncological malignancies and COVID-19. PATIENTS AND METHODS: We conducted a cross-sectional study of the first 100 patients hospitalised at the Instituto Nacional de Enfermedades Neoplasicas (Lima, Peru) who were positive for SARS-CoV-2 by reverse transcriptase (RT)-PCR during the period 30 March to 20 June. Clinicopathological variables of the oncological disease as well as risk factors, management and outcomes to COVID-19 were evaluated. RESULTS: The mean age was 43.5 years old (standard deviations: ±24.8) where 57% were male patients. In total, 44%, 37% and 19% were adult patients bearing solid tumours, adults with haematologic malignancies and paediatric patients, respectively. Hypertension was the most frequent comorbidity (23%) followed by chronic lung disease (10%). COVID-19-associated symptoms included cough (65%), fever (57%) and dyspnoea (56%). Twelve percent of patients were asymptomatic. Nosocomial infections were more frequent in paediatric patients (84.2%) than in adult patients (16.0%). Patients with uncontrolled oncological disease were most frequent (72%). Anaemia was present in 67% of patients, 68% had lymphopenia, 62% had ferritin value > 500 mcg/L, 85% had elevated lactate dehydrogenase (LDH), 83% D-dimer > 500 ng/mL and 80% C-Reactive Protein > 8 mg/L. The most common complication was acute respiratory failure (42%). Overall fatality rate was 39% where the main cause of mortality was acute respiratory distress syndrome (64.1%). CONCLUSION: Paediatric patients had better outcomes than adult populations, and a high number of asymptomatic carriers and nosocomial infection, early diagnosis are recommended. Considering oncological treatments 30 days before COVID-19 diagnosis, our data did not reveal an increased mortality.

Borderline Intellectual Functioning: Consensus and good practice guidelines

Introducción: El funcionamiento intelectual límite (FIL) se conceptualiza actualmente como la barrera que separa el funcionamiento intelectual «normal» de la discapacidad intelectual (CI 71-85). A pesar de su magnitud, su prevalencia no puede ser cuantificada y no se ha operativizado su diagnóstico. Objetivos: Elaborar un marco conceptual para el FIL y establecer directrices de consenso que permitan la aplicación de una atención integral centrada en la persona. Metodología: Se utilizó una metodología mixta cualitativa que combinaba un análisis del marco conceptual con el desarrollo de grupos nominales. Se realizó una revisión bibliográfica extensiva en bases de datos de evidencia médica, publicaciones científicas y literatura gris. Se estudió la información encontrada y se redactó un documento de marco conceptual sobre el FIL. Resultados: Las publicaciones centradas en el colectivo de personas con FIL son escasas. El término que mayor número de publicaciones arrojó fue «Borderline Intelligence». Se detectaron una serie de temas sobre los que era necesario alcanzar un consenso y se redactó un documento con las conclusiones del grupo de trabajo. Conclusiones: Es necesario establecer un consenso a nivel internacional sobre el constructo del FIL y sus criterios operativos, y desarrollar instrumentos específicos de detección y diagnóstico. También es necesario elaborar criterios que permitan calcular su incidencia y prevalencia. Saber qué intervenciones son las más adecuadas y cuáles son las necesidades de atención que presenta este colectivo es de vital importancia para implementar un modelo de atención integral centrado en la persona(AU)

Introduction: The Borderline Intellectual Functioning (BIF) is conceptualised as the frontier that delimits ‘‘normal’’ intellectual functioning from intellectual disability (IQ 71-85). In spite of its magnitude, its prevalence cannot be quantified and its diagnosis has not yet been defined. Objectives: To elaborate a conceptual framework and to establish consensus guidelines. Method: A mixed qualitative methodology, including frame analysis and nominal groups techniques, was used. The literature was extensively reviewed in evidence based medical databases, scientific publications, and the grey literature. This information was studied and a framing document was prepared. Results: Scientific publications covering BIF are scarce. The term that yields a bigger number of results is ‘‘Borderline Intelligence’’. The Working Group detected a number of areas in which consensus was needed and wrote a consensus document covering the conclusions of the experts and the framing document. Conclusions: It is a priority to reach an international consensus about the BIF construct and its operative criteria, as well as to develop specific tools for screening and diagnosis. It is also necessary to define criteria that enable its incidence and prevalence. To know what interventions are the most efficient, and what are the needs of this population, is vital to implement an integral model of care centred on the individual(AU)
