Unexpected appetitive events promote positive affective state in juvenile European sea bass.

Some animal species exhibit considerable physiological and behavioural alterations in response to captivity. It has been hypothesized, but rarely tested, that such changes reflect a negative affective state that is associated to this specific context. In the last years, judgement bias measures have emerged as reliable indicators of animal affective state, under the assumption that individuals in a negative affective state are more likely to evaluate ambiguous stimuli as negative and display therefore pessimistic behaviours. Here, we have developed a judgement bias task for juvenile European sea bass (Dicentrarchus labrax) aiming to measure optimism/pessimism in this marine species, which have previously been reported to show important dysregulations in captive settings. Our results show that juvenile sea bass exhibit a considerable bias towards pessimistic behaviours in laboratory settings. Furthermore, juveniles that received an unexpected positive event during the judgement bias test displayed more optimistic responses toward ambiguous stimuli as compared to control fish, indicating a positive change in their affective state induced by the appetitive experience. These results reveal a direct interaction of the internal affective state with decision-making processing under ambiguity in juvenile European sea bass, highlighting therefore the potential of judgement bias tests as a tool for the advancement and improvement of our understanding of welfare in finfish aquaculture.

Dataset for Sun dynamics from topological features.

The present study presents an extensive dataset meticulously curated from solar images sourced from the Solar and Heliospheric Observatory (SOHO), encompassing a range of spectral bands. This collaborative effort spans multiple disciplines and culminates in a robust and automated methodology that traverses the entire spectrum from solar imaging to the computation of spectral parameters and relevant characteristics. The significance of this undertaking lies in the profound insights yielded by the dataset. Encompassing diverse spectral bands and employing topological features, the dataset captures the multifaceted dynamics of solar activity, fostering interdisciplinary correlations and analyses with other solar phenomena. Consequently, the data's intrinsic value is greatly enhanced, affording researchers in solar physics, space climatology, and related fields the means to unravel intricate processes. To achieve this, an open-source Python library script has been developed, consolidating three pivotal stages: image acquisition, image processing, and parameter calculation. Originally conceived as discrete modules, these steps have been unified into a single script, streamlining the entire process. Applying this script to various solar image types has generated multiple datasets, subsequently synthesised into a comprehensive compilation through a data mining procedures. During the image processing phase, conventional libraries like OpenCV and Python's image analysis tools were harnessed to refine images for analysis. In contrast, image acquisition utilised established URL libraries in Python, facilitating direct access to original SOHO repository images and eliminating the need for local storage. The computation of spectral parameters involved a fusion of standard Python libraries and tailored algorithms for specific attributes. This approach ensures precise computation of a diverse array of attributes crucial for comprehensive analysis of solar images.

A review from 1996 to 2021 of tuning methodologies and controller structures applied for an unstable/stable (bio)reactor with imperfect mixing and bypass.

This paper presents a critical review of tuning methodologies and controller structures applied to the Cholette bioreactor. This (bio)reactor has been studied extensively by the automatic control community from the point of view of controller structures and tuning methodologies, from controllers with a single structure to nonlinear controllers, and from the synthesis method to the frequency response. Therefore, new trends and opportunities of study have been detected with regard to their operating points, controller structures and tuning methodologies which could be addressed for this system.

[Functional status and mortality in the elderly 3 months after hip fracture: when resources are limited]. / Estado funcional y mortalidad en el adulto mayor a tres meses de la fractura de cadera: cuando los recursos son limitados.

INTRODUCTION: hip fracture is the most common fracture in the elderly and its negative impact in functionality, life quality and expectancy are widely described. In Mexico, resources, infrastructure and programs for its attention are few and deficient. Associated factors to a better functional and life prognosis had been described in heterogeneous ways. The main objective of this work is to determine the associated factors to a better functional recovery and less mortality three months after hip fracture in the elderly. MATERIAL AND METHODS: geriatric assessment was performed in all older adult patients admitted to the hospital with hip fracture. Telephone monitoring was done three months after hospital discharge. Survival, Barthel index, and March Capacity Evaluation Scale (FAC) was interrogated. Descriptive analysis of the variables was performed. For outcomes measures, univariate analysis was done, since data didn't have normal distribution. Age and Barthel index before fracture were included in linear regression model to evaluate impact over mortality and march capacity. RESULTS: three-month mortality was of 26.3% of the patients, with in- hospital hyponatremia as a risk factor (OR, 3.87, p = 0.03). The median difference in pre fracture and post fracture Barthel index was -25 points (-5010). The variables associated with worse functional outcome was patient´s expressed fear to walk again (p = 0.05) and cognitive impairment (p = 0.032). 47.4% of the patients could walk, most of them classified in FAC 4. 28% of the patients, reported walking impairment. Living in urbanity, fear to walk (OR, 4.83, p = 0.031) and malnutrition (OR, 5.52, p = 0.016) were significantly associated with walking impairment. CONCLUSIONS: multifactorial intervention for better functional and survival outcomes three-months after hip fracture are needed, even more in middle-income countries.

INTRODUCCIÓN: la fractura de cadera es la más común en el adulto mayor y tiene gran impacto negativo en funcionalidad, calidad y sobrevida. En México la infraestructura, recursos y programas para su atención son escasos. Los factores asociados, mejor pronóstico funcional y de vida han sido descritos de forma heterogénea. El objetivo principal del estudio fue determinar los factores asociados con mayor recuperación funcional y menor mortalidad a tres meses de la fractura de cadera en el adulto mayor. MATERIAL Y MÉTODOS: se realizó valoración geriátrica integral a todos los pacientes mayores hospitalizados por fractura de cadera. Se dio seguimiento telefónico a tres meses del egreso hospitalario para revaloración de funcionalidad. Se interrogó sobrevida, escala de Barthel y FAC. Se realizó un análisis descriptivo de las variables. Para la valoración de desenlaces se hizo análisis univariado, ya que los datos no presentaron una distribución normal. Se incluyó edad y Barthel previo a fractura en un modelo de regresión lineal para valorar impacto en mortalidad y deambulación. RESULTADOS: la mortalidad a tres meses fue de 26.3%, con hiponatremia intrahospitalaria como factor de riesgo (OR, 3.87, p = 0.03). La mediana de diferencia en puntaje de Barthel preoperatorio y postoperatorio fue -25 puntos (-5010). Las variables asociadas a un peor desenlace funcional fue el miedo a volver a caminar (p = 0.05) y deterioro cognitivo (p = 0.032). De los pacientes, 47.4% lograba deambular, la mayoría clasificados con FAC 4; 28% de los pacientes no lograron deambulación. Vivir en urbanidad, el miedo a volver a caminar (OR, 4.83, p = 0.031) y un tamizaje positivo para malnutrición (OR, 5.52, p = 0.016) se asociaron a mayor incapacidad. CONCLUSIONES: es importante la intervención multifactorial para lograr mejores resultados funcionales y de sobrevida tres meses posteriores a la fractura de cadera.

Making integration foundational in population health intervention research: why we need 'Work Package Zero'.

OBJECTIVES: We aimed to identify when and how integration should take place within evaluations of complex population health interventions (PHIs). STUDY DESIGN: Descriptive analytical approach. METHODS: We draw on conceptual insights that emerged through (1) a working group on integration and (2) a diverse range of literature on case studies, small-n evaluations and mixed methods evaluation studies. RESULTS: We initially sought techniques to integrate analyses at the end of a complex PHI evaluation. However, this conceptualization of integration proved limiting. Instead, we found value in conceptualizing integration as a process that commences at the beginning of an evaluation and continues throughout. Many methods can be used for this type of integration, including process tracing, realist evaluation, congruence analysis, general elimination methodology/modus operandi, pattern matching and contribution analysis. Clearly signposting when integrative methods should commence within an evaluation should be of value to the PHI evaluation community, as well as to funders and related stakeholders. CONCLUSIONS: Rather than being a tool used at the end of an evaluation, we propose that integration is more usefully conceived as a process that commences at the start of an evaluation and continues throughout. To emphasize the importance of this timing, integration can be described as comprising 'Work Package Zero' within evaluations of complex PHIs.

Increased frequency of CD14+HLA-DR-/low cells in type 2 diabetes patients with poor glycemic control.

AIMS: Type 2 diabetes (T2DM) is associated with alterations of the immune response and T2DM patients have an increased risk for infections and certain sorts of cancers. Although CD14+HLA-DR-/low cells have emerged as important mediators of immunosuppression in several pathologies, including cancer and non-malignant diseases, the presence of these cells in T2DM is not fully characterized. METHODS: In this study, we evaluated the frequency of CD14+HLA-DR-/low cells in non-obese T2DM patients and their association with glycemic control. Peripheral blood mononuclear cells were isolated from healthy controls (HC, n = 24) and non-obese T2DM patients (n = 25), the population was evaluated by flow cytometry, and an analysis of correlation between cell frequencies and clinical variables was performed. RESULTS: CD14+HLA-DR-/low monocytes were expanded in patients with T2DM compared to HC regardless of weight. Among the subjects with T2DM, the frequency of CD14+HLA-DR-/low was higher in patients with poor glycemic control (HbA1c > 9%) compared to those with better glycemic control (HbA1c < 9%) and, positively correlated with the years since the diagnosis of T2DM, the age of the patients and the glycemic index. CONCLUSIONS: An increased frequency of CD14+HLA-DR-/low cells in the blood of T2DM patients was recorded. The influence of hyperglycemia seems to be independent of obesity, but related to glycemic control and age.

Effect of metabolic control on recurrent major adverse cardiovascular events and cardiovascular mortality in patients with premature coronary artery disease: Results of the Genetics of Atherosclerotic Disease study.

BACKGROUND AND AIMS: Coronary artery disease (CAD) is the leading cause of death around the world, and its rate of presentation is increasing at young ages. Despite the evidence that secondary prevention in CAD reduces the risk of recurrent major adverse cardiovascular events (MACE), no studies have analyzed the composite control of blood pressure, lipids, and glucose control in premature CAD. METHODS AND RESULTS: This was a real-world prospective cohort study of patients with premature CAD. The composite control in blood pressure <140/80 mmHg, LDL-C <70 mg/dL, non-HDL-C <100 mg/dL, and Hemoglobin A1c <8% was considered as metabolic control. The primary endpoint was the occurrence of non-fatal and fatal MACE. The data included 1042 patients with premature CAD. The mean age of the patients was 54.1 ± 8.1 years, 18.5% were women, and had a median follow-up of 59.1 ± 11.8 months. Of them, 7% had non-fatal MACE, and 4% had a fatal MACE. Overall, 21.3% achieved metabolic control, and 3.0% did not achieve any target. Cox regression analysis showed that percutaneous coronary intervention (Hazzard ratio = 1.883 [95% CI, 1.131-3.136]), C-reactive protein (1.046 [1.020-1.073]), blood pressure >140/90 mmHg (2.686 [1.506-4.791]), fibrates (2.032 [1.160-3.562]), calcium channel blockers (2.082 [1.158-3.744]) had greater risk to present a recurrent non-fatal MACE; whereas familial history of premature CAD (2.419 [1.240-4.721]), heart failure (2.139 [1.032-4.433]), LDL-C >70 mg/dL (4.594 [1.401-15.069]), and diuretics (3.328 [1.677-6.605]) were associated with cardiovascular mortality. CONCLUSIONS: The composite goal achievement in lipids, blood pressure and glucose, reduced the risk for recurrent MACE in 80%.

Onset of Nut Allergy in a Pediatric Cohort: Clinical and Molecular Patterns in the AFRUSEN Study.

BACKGROUND AND OBJECTIVE: Nut allergy is a growing problem, yet little is known about its onset in children. Objective: To characterize the onset of nut allergy in children in southern Europe. METHODS: The study population comprised consecutive patients up to 14 years of age who visited allergy departments with an initial allergic reaction to peanut, tree nut, or seed. The allergy work-up included a clinical history, food challenge, skin prick testing, determination of whole-extract sIgE, and ImmunoCAP ISAC-112 assay. RESULTS: Of the 271 children included, 260 were first diagnosed with nut allergy at a mean age of 6.5 years and at a mean (SD) of 11.8 (21.2) months after the index reaction. The most common culprit nuts at onset were walnut (36.5%), peanut (28.5%), cashew (10.4%), hazelnut (8.5%), pistachio (5.4%), and almond (5%). Onset of peanut allergy was more frequent in children ≤6 years and walnut in those aged >6 years (P=.032). In 65% of cases, the allergic reaction occurred the first time the patient consumed the nut, and 35% of reactions were anaphylactic. Overall, polysensitization to nuts was detected by skin prick testing in 64.9% of patients, although this rate was lower among walnut-allergic children (54.7%) and peanut-allergic children (54.1%) (P<.0001). Sensitization to 2S albumins was predominant (75%), especially Jug r 1 (52.8%), whereas sensitization to lipid transfer proteins was less relevant (37%). CONCLUSION: In the population we assessed, the onset of nut allergy occurred around 6 years of age, slightly later than that reported in English-speaking countries. Walnut was the main trigger, followed by peanut. 2S albumin storage proteins, especially Jug r 1, were the most relevant allergens. This study will help guide management and may contribute to preventive strategies in pediatric nut allergy.

STATIN trial: predictive performance of competing-risks model in screening for pre-eclampsia at 35-37 weeks' gestation.

OBJECTIVE: To examine the predictive performance of a previously reported competing-risks model of screening for pre-eclampsia (PE) at 35-37 weeks' gestation by combinations of maternal risk factors, mean arterial pressure (MAP), uterine artery pulsatility index (UtA-PI), serum placental growth factor (PlGF) and serum soluble fms-like tyrosine kinase-1 (sFlt-1) in a validation dataset derived from the screened population of the STATIN study. METHODS: This was a prospective third-trimester multicenter study of screening for PE in singleton pregnancies by means of a previously reported algorithm that combines maternal risk factors and biomarkers. Women in the high-risk group were invited to participate in a trial of pravastatin vs placebo, but the trial showed no evidence of an effect of pravastatin in the prevention of PE. Patient-specific risks of delivery with PE were calculated using the competing-risks model, and the performance of screening for PE by maternal risk factors alone and by various combinations of risk factors with MAP, UtA-PI, PlGF and sFlt-1 was assessed. The predictive performance of the model was examined by, first, the ability of the model to discriminate between the PE and no-PE groups using the area under the receiver-operating-characteristics curve (AUC) and the detection rate at a fixed false-positive rate of 10%, and, second, calibration by measurements of calibration slope and calibration-in-the-large. RESULTS: The study population of 29 677 pregnancies contained 653 that developed PE. In screening for PE by a combination of maternal risk factors, MAP, PlGF and sFlt-1 (triple test), the detection rate at a 10% false-positive rate was 79% (95% CI, 76-82%) and the results were consistent with the data used for developing the algorithm. Addition of UtA-PI did not improve the prediction provided by the triple test. The AUC for the triple test was 0.923 (95% CI, 0.913-0.932), demonstrating very high discrimination between affected and unaffected pregnancies. Similarly, the calibration slope was 0.875 (95% CI, 0.831-0.919), demonstrating good agreement between the predicted risk and observed incidence of PE. CONCLUSION: The competing-risks model provides an effective and reproducible method for third-trimester prediction of term PE. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Antecedentes: La alergia a frutos secos es un problema creciente. Sin embargo, existe poca información relativa al inicio de su establecimiento en la población infantil. Objetivos: Describir el debut de alergia a frutos secos en niños del sur de Europa. Métodos: Se incluyeron pacientes de hasta 14 años que acudieron de forma consecutiva a la consulta de alergia debido a una reacción inicial con cacahuete, frutos secos o semillas. El estudio alergológico incluyó realización de historia clínica, provocación oral, prueba intraepidérmica (SPT), determinación de IgE específica para extracto completo y mediante ImmunoCAP ISAC-112. Resultados: De los 271 niños incluidos, 260 se diagnosticaron de alergia a frutos secos por primera vez a los 6,5 años de media, habiendo tenido la reacción índice 11,8 (±21,2SD) meses antes. Los frutos secos responsables en el debut fueron nuez (36,5%), cacahuete (28,5%), anacardo (10,4%), avellana (8,5%), pistacho (5,4%) y almendra (5%). La instauración de la alergia a cacahuete fue más frecuente en niños ≤6 años y para nuez en >6 años (p=0,032). En el 65% de los casos, la reacción alérgica sucedió en la primera vez en que el paciente consumía el fruto seco, y el 35% de las reacciones fueron anafilaxia. En conjunto, la polisensibilización a frutos secos se identificó en el 64,9% de los pacientes, aunque este porcentaje fue significativamente inferior en niños alérgicos a nuez (54,7%) y cacahuete (54,1%) (p<0,0001). La sensibilización a albúminas 2S fue predominante (75%), especialmente a Jug r 1 (52,8%), mientras que la identificación de LTP fue menos relevante (37%). Conclusión: En nuestra población, el debut de alergia a frutos secos sucedió alrededor de los 6 años de edad, ligeramente más tardío al reportado en países anglosajones. La nuez fue el principal desencadenante, seguido de cacahuete, y las albúminas de almacenamiento 2S, especialmente Jug r 1, fueron los alérgenos más relevantes (AU)

Conventional and advanced echocardiographic assessment of systolic function in dogs sedated with dexmedetomidine or acepromazine.

Dexmedetomidine and acepromazine, sedatives commonly used in dogs have opposite vascular effects, resulting in afterload increase and decrease, respectively. This could variably affect systolic myocardial function. Previous echocardiographic studies assessing the cardiovascular effects of these drugs used conventional echocardiography, while advanced techniques such as speckle tracking echocardiography (STE) and tissue Doppler imaging (TDI), which are known to provide a more accurate assessment of systolic function, have been rarely used for this aim. Moreover, in the few studies using advanced techniques, the drugs where combined with opioids. Therefore, the main objective of this prospective study was to assess systolic myocardial function by conventional and advanced echocardiography (STE and TDI), in dogs sedated exclusively with dexmedetomidine or acepromazine not combined with other drugs. Twenty healthy dogs were randomly divided into two groups, Group A (acepromazine, 20 µg/kg IM), and Group D (dexmedetomidine, 5 µg/kg IM), cardiovascular parameters were assessed before sedation (T0), and thirty minutes afterwards (T1). Systolic arterial pressure and heart rate decreased in both groups at T1 as compared to T0. Only one conventional echocardiographic raw variable (left ventricular internal dimension in systole) and three out of five advanced echocardiographic variables (radial TDI systolic velocities at the epicardial region of the left ventricular free wall, longitudinal TDI systolic velocities of the septal mitral valve annulus and the STE-derived left ventricular global strain), were affected in Group D. A systolic impairment was observed in Group D and better estimated by advanced echocardiography. In Group A, only the end diastolic voume index (conventional echocardiography) was decreased. Both protocols seem to induce echocardiographic changes more likely secondary to their vascular action.

Experiencias luego del diagnóstico de demencia: aportes desde la perspectiva de los pacientes / Experiences following the diagnosis of dementia: contributions from the patients' perspective

INTRODUCCIÓN: Comunicar el diagnóstico de demencia es un importante desafío médico, por lo que tiende a ser una práctica poco frecuente no obstante el derecho de los pacientes a ser informados de sus diagnósticos. En Chile, existe investigación que describe las implicancias del diagnóstico de demencia en el sistema familiar y cuidadores informales, pero no se ha abordado esta experiencia desde la perspectiva de los pacientes, por lo que sus implicancias son también desconocidas. OBJETIVO: Describir las experiencias luego del diagnóstico de demencia desde la perspectiva de los pacientes. MATERIAL Y MÉTODO: Estudio cualitativo. Se realizó entrevistas a 11 personas, 6 hombres y 5 mujeres, con edad promedio 70 años (64-82), quienes recibieron el diagnóstico de demencia tipo Alzheimer en etapa leve y fueron informados de su diagnóstico por Neuróloga tratante. Las entrevistas transcritas fueron analizadas mediante análisis de contenido con codificación abierta, usando software NVivo 11.0 Pro. RESULTADOS: Las siguientes cinco categorías temáticas genéricas fueron producidas a partir del análisis de las entrevistas, describiendo la experiencia de los pacientes luego de recibir el diagnóstico: rol capacitante de la familia, ser informado/a sobre la demencia, autoestigma, ambivalencia en contar el diagnóstico, y estrategias de adaptación al diagnóstico. CONCLUSIONES: Los resultados de este estudio informan de necesidades específicas de los pacientes luego de ser informados del diagnóstico de demencia tipo Alzheimer. Se presentan consideraciones para el abordaje local del diagnóstico por equipos de salud y apoyo social que enfrentan el desafío de planificar la atención de personas con trastornos cognitivos y sus familias.

INTRODUCTION: Communicating the diagnosis of dementia is a medical challenge. Despite the the patients' right to be informed of their diagnosis, diagnostic disclosure is globally underperformed. In Chile, previous research has addressed the implications of diagnosis from the perspectives of families and family caregivers, but the perspectives and implications from the patients' perspectives remain unknown. OBJECTIVE: To describe the experiences of patients following the diagnosis of dementia. MATERIAL AND METHODS: Qualitative study. Interviews were performed to 11 individuals who had received the diagnosis of early-stage dementia of the Alzheimer's type, 5 women and 6 men, average age 70 years old (64-82). Interviews transcripts were analyzed using content analysis with open coding, using software NVivo 11.0 Pro. RESULTS: The following five generic categories were produced from the interpretation of interviews to describe the experience of patients after being informed of a diagnosis of dementia: the enabling role of families, being informed about dementia, self-stigma, ambivalence on sharing the diagnosis, and coping strategies. CONCLUSIONS: Findings report specific unmet needs of patients who have been communicated of the diagnosis of dementia of the Alzheimer's type. Suggestions are presented to inform local health care and social support teams that face the challenge of developing interventions to support people with dementia and their families.

Prediction of pre-eclampsia in twin pregnancy by maternal factors and biomarkers at 11-13 weeks' gestation: data from EVENTS trial.

OBJECTIVES: First, to validate a previously developed model for screening for pre-eclampsia (PE) by maternal characteristics and medical history in twin pregnancies; second, to compare the distributions of mean arterial pressure (MAP), uterine artery pulsatility index (UtA-PI), serum placental growth factor (PlGF) and serum pregnancy-associated plasma protein-A (PAPP-A) in twin pregnancies that delivered with PE to those in singleton pregnancies and to develop new models based on these results; and, third, to examine the predictive performance of these models in screening for PE with delivery at < 32 and < 37 weeks' gestation. METHODS: Two datasets of prospective non-intervention multicenter screening studies for PE in twin pregnancies at 11 + 0 to 13 + 6 weeks' gestation were used. The first dataset was from the EVENTS (Early vaginal progesterone for the preVention of spontaneous prEterm birth iN TwinS) trial and the second was from a previously reported study that examined the distributions of biomarkers in twin pregnancies. Maternal demographic characteristics and medical history from the EVENTS-trial dataset were used to assess the validity of risks from our previously developed model. The combined data from the first and second datasets were used to compare the distributional properties of log10 multiples of the median (MoM) values of UtA-PI, MAP, PlGF and PAPP-A in twin pregnancies that delivered with PE to those in singleton pregnancies and develop new models based on these results. The competing-risks model was used to estimate the individual patient-specific risks of delivery with PE at < 32 and < 37 weeks' gestation. Screening performance was measured by detection rates (DR) and areas under the receiver-operating-characteristics curve. RESULTS: The EVENTS-trial dataset comprised 1798 pregnancies, including 168 (9.3%) that developed PE. In the validation of the prior model based on maternal characteristics and medical history, calibration plots demonstrated very good agreement between the predicted risks and the observed incidence of PE (calibration slope and intercept for PE < 32 weeks were 0.827 and 0.009, respectively, and for PE < 37 weeks they were 0.942 and -0.207, respectively). In the combined data, there were 3938 pregnancies, including 339 (8.6%) that developed PE and 253 (6.4%) that delivered with PE at < 37 weeks' gestation. In twin pregnancies that delivered with PE, MAP, UtA-PI and PlGF were, at earlier gestational ages, more discriminative than in singleton pregnancies and at later gestational ages they were less so. For PAPP-A, there was little difference between PE and unaffected pregnancies. The best performance of screening for PE was achieved by a combination of maternal factors, MAP, UtA-PI and PlGF. In screening by maternal factors alone, the DR, at a 10% false-positive rate, was 30.6% for delivery with PE at < 32 weeks' gestation and this increased to 86.4% when screening by the combined test; the respective values for PE < 37 weeks were 24.9% and 41.1%. CONCLUSIONS: In the assessment of risk for PE in twin pregnancy, we can use the same prior model based on maternal characteristics and medical history as reported previously, but in the calculation of posterior risks it is necessary to use the new distributions of log10 MoM values of UtA-PI, MAP and PlGF according to gestational age at delivery with PE. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Estimación de costos unitarios directos de atención curativa de dengue en Ecuador 2020 / Estimate of direct unit costs of curative Dengue care in Ecuador 2020

El dengue es una enfermedad viral aguda transmitida a través de la picadura del mosquito (artrópodo) Aedes aegypti infectado con cualquiera de los serotipos de virus dengue. Son virus envueltos, de 40 a 50 nm de diámetro, con cápside icosaédrica y genoma de ácido ribonucleico (ARN) monocatenario, no segmentado, de polaridad positiva perteneciente al género flavivirus de la familia Flaviviridae. El análisis filogenético de las distintas cepas del virus dengue indica que la diseminación global ha dado lugar a distintos genotipos dentro de cada serotipo. En el quinquenio 2015-2020, en Ecuador, se notificaron en toda la región 76.085 casos de dengue. La atención unitaria hospitalaria para el tratamiento del dengue de las unidades de atención sanitaria hospitalarias (A, B, C), generaron un costo total promedio de 498,04 $ con una desviación estándar de ± 40,36, en el Ecuador para el año 2020. Cabe considerar, por otra parte, que el costo unitario directo promedio en ($) de la atención sanitaria en las entidades hospitalarias estudiadas en la presente investigación, generanron un gasto total para el tratamiento hospitalario de 9.585.114,02. Al mismo tiempo en los 2.135 pacientes diagnosticados con dengue que presentaron signos de alarma y requirieron cuatro días de hospitalización, señalando un gasto total para el tratamiento de 1.471.385,06. Por su parte los 51 pacientes que fueron diagnosticados con dengue grave, generaron un costo unitario total en las unidades hospitalarias de 134.152,54. Los resultados son conservadores, porque algunos componentes importantes no se incluyeron en los costos relacionados con el dengue.En ausencia de vacunación, y siendo los programas de control del vector la estrategia básica para mitigar la propagación del dengue, esta enfermedad seguirá produciendo una carga económica y social considerable en el Ecuador, lo que se refleja en el costo total de la enfermedad(AU)

Dengue is an acute viral disease transmitted through the bite of the mosquito (arthropod) Aedes aegypti infected with any of the dengue virus serotypes. They are enveloped viruses, 40 to 50 nm in diameter, with an icosahedral capsid and a single-stranded, non-segmented ribonucleic acid (RNA) genome of positive polarity belonging to the genus Flavivirus of the Flaviviridae family. Phylogenetic analysis of the different dengue virus strains indicates that global spread has given rise to different genotypes within each serotype. In the five-year period 2015-2020, in Ecuador, 76,085 cases of dengue were reported throughout the region. The hospital unit care for the treatment of dengue in the hospital health care units (A, B, C), generated an average total cost of $ 498.04 with a standard deviation of ± 40.36, in Ecuador for the year 2020. It should be considered, on the other hand, that the average direct unit cost in ($) of health care in the hospital entities studied in the present investigation, generated a total cost for hospital treatment of 9,585,114.02. At the same time, in the 2,135 patients diagnosed with dengue who presented alarm signs and required four days of hospitalization, indicating a total cost for treatment of 1,471,385.06. On the other hand, the 51 patients who were diagnosed with severe dengue, generated a total unit cost in the hospital units of 134,152.54. The results are conservative, because some important components were not included in the costs related to dengue. In the absence of vaccination, and with vector control programs the basic strategy to mitigate the spread of dengue, this disease will continue to produce an economic burden and considerable social in Ecuador, which is reflected in the total cost of the disease(AU)

Telemedicina con telemonitorización en el seguimiento de pacientes con COVID-19 / Tracing of COVID-19 patients by telemedicine with telemonitoring

OBJETIVO: Evaluar si la telemedicina con telemonitorización es una herramienta clínicamente útil y segura para el seguimiento de pacientes con COVID-19. MÉTODOS: Estudio observacional prospectivo de los pacientes con diagnóstico de COVID-19 por PCR positiva y considerados de alto riesgo que se siguieron con telemedicina y telemonitorización en el Área Sanitaria de Lugo entre el 17 de marzo y el 17 de abril de 2020. Se incluyeron dos grupos de pacientes: seguimiento ambulatorio desde el inicio y tras el alta hospitalaria. Cada paciente remitió un cuestionario clínico al día con su temperatura y saturación de oxígeno 3 veces al día. El seguimiento fue proactivo contactando con todos los pacientes al menos una vez al día. RESULTADOS: Se incluyeron 313 pacientes (52,4% mujeres) con edad media 60,9 (DS 15,9) años. Otros 2 pacientes rehusaron entrar en el programa. Desde el inicio se siguieron ambulatoriamente 224 pacientes y 89 tras su alta hospitalaria. Entre los primeros, 38 (16,90%) se remitieron a Urgencias en 43 ocasiones con 18 (8,03%) ingresos y 2 fallecidos. En los domicilios no hubo fallecimientos ni urgencias vitales. Incluyendo a los pacientes tras hospitalización, el seguimiento se realizó en 304 casos. Un paciente reingresó (0,32%) y otro abandonó (0,32%). El tiempo medio de seguimiento fue 11,64 (SD 3,58) días y en los 30 días del estudio 224 (73,68%) pacientes fueron dados de alta. CONCLUSIONES: Nuestros datos sugieren que la telemedicina con telemonitorización domiciliaria, utilizada de forma proactiva, permite un seguimiento clínicamente útil y seguro en pacientes con COVID-19 de alto riesgo

AIM: To asses if telemedicine with telemonitoring is a clinically useful and secure tool in the tracking of patients with COVID-19. METHODS: A prospective observational study of patients with COVID-19 diagnosis by positive PCR considered high-risk tracked with telemedicine and telemonitoring was conducted in the sanitary area of Lugo between March 17th and April 17th, 2020. Two groups of patients were included: Outpatient Tracing from the beginning and after discharge. Every patient sent a daily clinical questionnaire with temperature and oxygen saturation 3 times a day. Proactive monitoring was done by getting in touch with every patient at least once a day. RESULTS: 313 patients (52.4% female) with a total average age of 60.9 (DS 15.9) years were included. Additionally, 2 patients refused to join the program. Since the beginning, 224 were traced outpatient and 89 after being discharged. Among the first category, 38 (16.90%) were referred to Emergency department on 43 occasions; 18 were hospitalized (8.03%), and 2 deceased. Neither deaths nor a matter of vital emergency occurred at home. When including patients after admissions monitoring was done in 304 cases. One patient re-entered (0.32%) to the hospital, and another one left the program (0.32%). The average time of monitoring was 11.64 (SD 3.58) days, and 224 (73.68%) patients were discharged during the 30 days of study. CONCLUSIONS: Our study suggests that telemedicine with home telemonitoring, used proactively, allows for monitoring high-risk patients with COVID-19 in a clinically useful and secure way

Type 2 diabetes mellitus metabolic control correlates with the phenotype of human monocytes and monocyte-derived macrophages.

AIMS: Monocytes and macrophages express cell-surface markers indicative of their inflammatory and activation status. In this study, we investigated whether these markers are affected or correlated in non-obese T2D subjects, or glycemic/metabolic control variables. METHODS: Clinical data was recorded, and peripheral blood drawn from T2D patients (n = 28) and control subjects (n = 27). Isolated monocytes were evaluated by flow cytometry for the expression of CD14, CD16, and the phenotypic markers for the different states of activation spectrum, such as pro-inflammatory (M1) (HLA-DR, CD86), anti-inflammatory/pro-resolving (M2) (CD163, CD206, MERTK, PD-L1) and metabolically-activated (MMe) (CD36, ABCA-1). From a subset of individuals, monocytes-derived macrophages (MDM) were obtained and evaluated for phenotypic markers. A correlation analysis was performed between the clinical variables and the marker expression. RESULTS: The frequency of CD14++CD16- monocytes was lower in T2D patients and it correlates negatively with poor control in glycemic and metabolic variables. T2D monocytes expressed lower levels of HLA-DR, CD86, PD-L1, and CD163, which correlated negatively with poor metabolic control. In MDM from T2D patients, HLA-DR, CD86 and CD163 expression was lower and it inversely correlated with deficient glycemic or metabolic control parameters. CONCLUSION: The glycemic/metabolic control associated with T2D influences monocyte and MDM phenotypes toward an immune-suppressive phenotype.

A New Genus and Two New Species of the Subfamily Nesomesochorinae Ashmead (Insecta: Hymenoptera: Ichneumonidae).

Nesomesochorinae is a rather small subfamily of Darwin wasps (Insecta: Hymenoptera: Ichneumonidae), only with three described genera. We recognize a fourth nesomesochorine genus from Perú and describe it as a new genus, Bina Shimizu & Alvarado gen. nov. The new genus is distinguished from previously described genera of Nesomesochorinae by the following combination of character states: mandible parallel-sided proximally and abruptly strongly narrowed ventroapically so that its lower apical tooth is much smaller and sharper than upper tooth; propodeum with lateromedian longitudinal carinae between anterior and posterior transverse carinae developed on more than posterior 0.9 so that the area superomedia is more or less enclosed; thyridium of 2nd metasomal tergite sometimes very large; 1st metasomal tergite stout and arched; body highly shiny. Bina gen. nov. comprises two species also described as new to science: B. huayrurae Shimizu & Alvarado sp. nov. (type species of Bina gen. nov.) and B. nigra Shimizu & Alvarado sp. nov. Identification keys to genera of Nesomesochorinae and to species of Bina gen. nov. are provided.
