Automated Quantification of Pneumonia Infected Volume in Lung CT Images: A Comparison with Subjective Assessment of Radiologists.

OBJECTIVE: To help improve radiologists' efficacy of disease diagnosis in reading computed tomography (CT) images, this study aims to investigate the feasibility of applying a modified deep learning (DL) method as a new strategy to automatically segment disease-infected regions and predict disease severity. METHODS: We employed a public dataset acquired from 20 COVID-19 patients, which includes manually annotated lung and infections masks, to train a new ensembled DL model that combines five customized residual attention U-Net models to segment disease infected regions followed by a Feature Pyramid Network model to predict disease severity stage. To test the potential clinical utility of the new DL model, we conducted an observer comparison study. First, we collected another set of CT images acquired from 80 COVID-19 patients and process images using the new DL model. Second, we asked two chest radiologists to read images of each CT scan and report the estimated percentage of the disease-infected lung volume and disease severity level. Third, we also asked radiologists to rate acceptance of DL model-generated segmentation results using a 5-scale rating method. RESULTS: Data analysis results show that agreement of disease severity classification between the DL model and radiologists is >90% in 45 testing cases. Furthermore, >73% of cases received a high rating score (≥4) from two radiologists. CONCLUSION: This study demonstrates the feasibility of developing a new DL model to automatically segment disease-infected regions and quantitatively predict disease severity, which may help avoid tedious effort and inter-reader variability in subjective assessment of disease severity in future clinical practice.

Mixed Adenoneuroendocrine Carcinoma in the Ampulla of Vater: Case Report

A mixed non-neuroendocrine neuroendocrine neoplasm is a mixed neoplasm with a neuroendocrine component combined with a non-neuroendocrine component. It has a low incidence and limited studies, but with evidence of being an aggressive entity associated with poor survival. We present the case of a 58-year-old woman admitted with clinical symptoms of abdominal pain in the left hypochondrium associated with generalized jaundice and feverish spikes with an imaging diagnosis of bile duct dilation secondary to distal choledocholithiasis. Endoscopic retrograde cholangiopancreatography (ERCP) was performed, finding a significant papilla with a neoplastic appearance, which was biopsied and histopathologically analyzed. The diagnosis of mixed carcinoma with a component of high-grade poorly differentiated neuroendocrine carcinoma and a component of mucinous carcinoma was confirmed. Therefore, we decided to schedule a pancreaticoduodenectomy.

La neoplasia neuroendocrina no neuroendocrina mixta es una neoplasia mixta con un componente neuroendocrino combinado con un componente no neuroendocrino. Esta presenta una incidencia baja y estudios limitados, pero con evidencia de ser una entidad agresiva asociada a una pobre supervivencia. Presentamos el caso de una mujer de 58 años que ingresó por un cuadro clínico de dolor abdominal en el hipocondrio izquierdo asociado a ictericia generalizada y picos febriles con diagnóstico imagenológico de dilatación de la vía biliar secundaria a coledocolitiasis distal, por lo que se realizó una colangiopancreatografía retrógrada endoscópica (CPRE) en la que se encontró una papila mayor de aspecto neoplásico a la cual se le realizó una biopsia analizada histopatológicamente y se confirmó el diagnóstico de carcinoma mixto con componente de carcinoma neuroendocrino pobremente diferenciado de alto grado y componente de carcinoma mucinoso, por lo cual se decidió programar una pancreatoduodenectomía.

Evidence of emotion dysregulation as a core symptom of adult ADHD: A systematic review.

Attention Deficit Hyperactivity Disorder (ADHD) is a developmental disorder, with an onset in childhood, that accompanies the person throughout their life, with prevalence between 3 and 5% in adults. Recent studies point towards a fourth core symptom of the disorder related to the emotional information processing that would explain the repercussions that ADHD has on the social, academic, and professional life of the people affected. This review aims to describe emotion dysregulation features as well as the brain activity associated in adults with ADHD. A search of the scientific literature was launched in specialized databases: PsycInfo, Medline, Eric, PsycArticle, Psicodoc and Scopus, following PRISMA guidelines. Twenty-two articles met the inclusion criteria: (a) an ADHD clinical diagnosis, (b) participants over 18 years old, (c) emotion regulation measurement, (d) empirical studies, and (c) in English. Due to the heterogeneity of the studies included, they were classified into three sections: measures and features of emotion regulation (ER) in people with ADHD, neurological and psychophysiological activity related to ER, and treatments. The studies found that meet the selection criteria are scarce and very heterogeneous both in aims and in sample features. Adults with ADHD show a more frequent use of non-adaptive emotion regulation strategies compared to people without ADHD symptoms. Moreover, emotion dysregulation was associated with symptom severity, executive functioning, psychiatric comorbidities, and even with criminal conviction. Different patterns of brain activity were observed when people with and without ADHD were compared. These results may suggest that psychopharmacological treatments as well as behavioral therapies could be useful tools for improving emotional difficulties in adult ADHD.

Supervivencia global y libre de enfermedad en mujeres con sobrepeso/obesidad al diagnóstico de cáncer de mama: Un estudio observa-cional de centro único / Overall and disease-free survival in women being over-weight/obesityat the diagnosis of breast cancer. A single-center observationalstudy

Introducción:El objetivo del presente estudio fue evaluar las características clínicas, patológi-cas e histológicas tumorales y su asociación con la recurrencia, metástasis y pronóstico en términos de supervivencia global y libre de enfermedad, de las pacientes que padecen sobre-peso u obesidad al momento del diagnóstico de cáncer de mama.Materiales y métodos:Se condujo un estudio descriptivo,longitudinal,retrospectivo, en un centro oncológico de referencia de Medellín. Se recolectó información de pacientes mayores de 18 años, con cáncer de mama infiltrante temprano y avanzado, entre los años 2012 ­2017, quienes presentaran IMC ≥ 25 kg/m2 al momento del diagnóstico. Las medianas de supervi-vencia se calcularon a través de curvas de Kaplan Meier y las diferencias mediante Log Rank Test.Resultados:Se analizó información de 1.349 pacientes. La mortalidad por todas las causas fue de 13.6% y aumentó proporcionalmente con el IMC (HR = 1.03, IC 1.0-1.05). Se identifica-ron 12.6% de recurrencias y el riesgo con el aumento de IMC no fue estadísticamente signifi-cativo (HR =1.02, IC 0.99 -1.05). Características como mala diferenciación tumoral, invasión linfovascular y estadio tumoral se asociaron de forma univariada con mayor mortalidad.Conclusión:Se demostró una asociación positiva e independiente entre el IMC elevado, la mortalidad y el riesgo de recurrencia en pacientes con cáncer de mama. Así como una aso-ciación con fenotipos tumorales agresivos y características de peor pronóstico. Se sugiere considerar modificaciones en el estilo de vida y un manejo multidisciplinario, como estrate-gias que posiblemente impacten en estos desenlaces

Introduction:The objective of the present study was to evaluate the clinical, pathological, and histological characteristics of tumors and their associations with recurrence, metastasis,and prognosis in terms of overall and disease-free survival inoverweight or obese patients at the time of diagnosis.Materials and methods: A descriptive, longitudinal, retrospective study was conducted at a reference cancer center in Medellin. Information was collected from patients older than 18 years of age with early or advanced infiltrating breast cancer between 2012 and 2017 who had a BMI ≥ 25 kg/m2 at the time of diagnosis. Median survival rates were calculated using Kaplan­Meier curves, and differences were determined using the log-rank test.Results: Information from 1,349 patients was analyzed. All-cause mortality was 13.6% and increased proportionally with BMI (HR = 1.03, CI 1.0-1.05). A total of 12.6% of the recurrences were identified,and the risk with increasing BMI was not significantly different(HR =1.02, CI 0.99 -1.05). Patient characteristicssuch as poor tumor differentiation, lymphovascular inva-sion, and tumor stage were univariately associated with increasedmortality.Conclusion: Positiveand independent associations weredemonstrated between high BMI and mortality and between high BMI and the risk of recurrence in patients with breast cancer. In addition, there wasan association betweenaggressive tumor phenotypes and worse prog-nostic characteristics. Lifestylemodifications and multidisciplinary management should be considered strategies for impactingthese outcomes

[Mental Health Care of Health Workers During Covid-19: Recommendations Based on Evidence and Expert Consensus]. / Cuidado de la salud mental del personal de salud durante COVID-19: recomendaciones basadas en evidencia y consenso de expertos.

INTRODUCTION: The crisis situation generated by COVID-19 and the measures adopted have generated social changes in the normal dynamics of the general population and especially for health workers, who find themselves caring for patients with suspected or confirmed infection. Recent studies have detected in them depression and anxiety symptoms and burnout syndrome, with personal and social conditions impacting their response capacity during the health emergency. Our aim was to generate recommendations for the promotion and protection of the mental health of health workers and teams in the first line of care in the health emergency due to COVID-19. METHODS: A rapid literature search was carried out in PubMed and Google Scholar, and an iterative expert consensus and through electronic consultation, with 13 participants from the areas of psychology, psychiatry and medicine; the grading of its strength and directionality was carried out according to the international standards of the Joanna Briggs Institute. RESULTS: Thirty-one recommendations were generated on self-care of health workers, community care among health teams, screening for alarm signs in mental health and for health institutions. CONCLUSIONS: The promotion and protection activities in mental health to face the health emergency generated by COVID-19 worldwide can include coordinated actions between workers, health teams and health institutions as part of a comprehensive, community care, co-responsible and sustained over time.

Pharmacogenetic polymorphisms affecting bisoprolol response.

ß-blockers are commonly prescribed to treat multiple cardiovascular (CV) diseases, but, frequently, adverse drug reactions and intolerance limit their use in clinical practice. Interindividual variability in response to ß-blockers may be explained by genetic differences. In fact, pharmacogenetic interactions for some of these drugs have been widely studied, such as metoprolol. But studies that explore genetic variants affecting bisoprolol response are inconclusive, limited or confusing because of mixed results with other ß-Blockers, different genetic polymorphisms observed, endpoint studied etc. Because of this, we performed a systematic review in order to find relevant genetic variants affecting bisoprolol response. We have found genetic polymorphism in several genes, but most of the studies focused in ADRB variants. The ADRB1 Arg389Gly (rs1801253) was the most studied genetic polymorphism and it seems to influence the response to bisoprolol, although studies are inconclusive. Even, we performed a meta-analysis about its influence on systolic/diastolic blood pressure in patients treated with bisoprolol, but this did not show statistically significant results. In conclusion, many genetic polymorphisms have been assessed about their influence on patients´ response to bisoprolol and the ADRB1 Arg389Gly (rs1801253) seems the most relevant genetic polymorphism in this regard but results have not been confirmed with a meta-analysis. Our results support the need of further studies about the impact of genetic variants on bisoprolol response, considering different genetic polymorphisms and conducting single and multiple SNPs analysis, including other clinical parameters related to bisoprolol response in a multivariate study.

Mental health interventions for college and university students during the COVID-19 pandemic: A critical synthesis of the literature.

BACKGROUND: The aim of the study is to compare the emotional effects of COVID-19 among three different groups, namely: health personnel, medical students, and a sample of the general population. METHODS: 375 participants were recruited for this study, of which 125 were medical students (preclinical studies, 59; clinical studies, 66), 125 were health personnel (COVID-19 frontline personnel, 59; personnel not related with COVID-19, 66), and 125 belonged to the general population. The PHQ-9, GAD-7, and CPDI scales were used to assess the emotional impact. A multinomial logistic regression was performed to measure differences between groups, considering potential confounding factors. RESULTS: Regarding CPDI values, all other groups showed reduced values compared to COVID-19 frontline personnel. However, the general population, preclinical and clinical medical students showed increased PHQ-9 values compared to COVID-19 frontline personnel. Finally, confounding factors, gender and age correlated negatively with higher CPDI and PHQ-9 scores. CONCLUSIONS: Being frontline personnel is associated with increased COVID-19-related stress. Depression is associated, however, with other groups not directly involved with the treatment of COVID-19 patients. Female gender and younger age correlated with COVID-19-related depression and stress.

Mental health care of health workers during Covid-19: Recommendations based on evidence and expert consensus.

Intervenciones para la salud mental de estudiantes universitarios durante la pandemia por COVID-19: una síntesis crítica de la literatura / Mental health interventions for college and university students during the COVID-19 pandemic: a critical synthesis of the literature

RESUMEN Introducción: Los estudiantes de educación superior son una población vulnerable a los trastornos mentales, más aún durante la pandemia por COVID-19. Su salud mental se ha visto afectada por el confinamiento, las dificultades en el desarrollo de las actividades académicas y las exigencias de las nuevas modalidades pedagógicas. Se planteó entonces la pregunta: en las instituciones de educación superior, ¿cuáles acciones en torno a a) promoción y prevención, b) atención a síntomas mentales y c) adaptaciones pedagógicas pueden desarrollarse con el fin de mejorar la salud mental de sus estudiantes? Métodos: Síntesis crítica a partir de la revisión sistemática de la literatura. Se realizó la búsqueda de artículos científicos de alcance descriptivo, analítico, experimental o evaluativo, así como recursos web de organizaciones relacionadas con el tema. Se realizó una síntesis en función de los 3 focos de la pregunta mediante comparación constante, hasta realizar la agrupación de acciones por similitud en los actores que las ejecutarían y recibirían. Se anticipó una baja calidad de la evidencia, por lo que no se realizó evaluación estandarizada. Resultados: Se exploraron 68 artículos y 99 recursos web. Después de la revisión del texto completo se incluyeron 12 artículos científicos y 11 recursos web. Como lineamentos generales, se encontró que la propuesta más frecuente es el diseño de un programa estructurado específico para el tema de salud mental en las instituciones educativas, que sea multidisciplinario, incluyente, dinámico y sensible a la cultura. Las acciones deben ser divulgadas periódicamente para que los estudiantes y demás miembros de la comunidad educativa las tengan claras, e idealmente se propone mantenerlas hasta el periodo pospandémico e incluir a los egresados. Para a) la promoción y prevención, se encontró la psicoeducación por vía electrónica, donde se expliquen estilos de vida saludable, reacciones emocionales en pandemia, estrategias de afrontamiento y signos de alarma. Se propone la participación de los pares como estrategia de apoyo y espacios de interacción social que no se enfoquen únicamente en aspectos académicos. Se reporta la necesidad de cribar síntomas mentales por medio de envío frecuente de formularios en línea o aplicaciones móviles, donde también se indague por la satisfacción de las necesidades básicas y tecnológicas. En cuanto a b) atención de síntomas mentales, una de las acciones que se encontró con mayor frecuencia es disponer de un centro de consultoría que sea capaz de realizar atención en salud mental por vía telefónica, por tecnologías e incluso presencial, con atención permanente las 24 h o equipos de respuesta rápida ante una situación de crisis, como la conducta suicida y la violencia doméstica. Para c) las adaptaciones pedagógicas, se señala como requisito indispensable la comunicación fluida para tener instrucciones claras sobre el desarrollo de las actividades académicas para disminuir la incertidumbre y, por ende, la ansiedad y favorecer la gestión del tiempo por el estudiante. Los profesores y pedagogos de la institución pueden ofrecer asesorías directas (por videollamadas o reuniones de grupos en línea) para proveer apoyo en hábitos de estudios, materias propias de cada carrera y salud mental. Conclusiones: Los recursos incluidos proponen que la institución educativa cree un programa que aborde específicamente la salud mental de los estudiantes. Esta síntesis puede proveer lineamientos que faciliten la toma de decisiones, sin perder de vista que la institución y el estudiante están inmersos en un contexto complejo, con circunstancias y otros actores en varios niveles que también intervienen en la salud mental. Se requieren investigaciones sobre la evolución de la situación de salud mental y el efecto de las acciones que se vayan tomando.

ABSTRACT Background: College and university students are a population vulnerable to mental disorders, especially during the COVID-19 pandemic. Their mental health has been affected by confinement, difficulties in the development of academic activities, and the demands of new pedagogical modalities. We aimed to respond to the question: what are the actions around a) promotion and prevention, b) mental symptoms care, and c) pedagogical adaptations that can be developed in order to improve the mental health of college and university students? Methods: We conducted a critical synthesis from a systematic review of the literature. A search was made for scientific articles with descriptive, analytical, empirical or evaluative designs, as well as web resources of organizations related to the topic. A synthesis was carried out based on the three aspects of the question by means of a constant comparative method, until the aggregation of actions by similarity in the actors. We anticipated low evidence quality; therefore, a standardized evaluation was not performed. Results: We explored 68 articles and 99 web resources. After reviewing the full text, 12 scientific articles and 11 web resources were included. As general guidelines, we found that the most frequent suggestion is the design of a specific structured mental health program within universities, one that should be multidisciplinary, inclusive, dynamic and culturally sensitive. All actions taken by the university should be reported and published periodically so that students and other members of the university community are clear about them. Ideally, it is suggested to keep them until the post-pandemic period and include alumni. Regarding a) promotion and prevention, digital psychoeducation was recommended, with information about healthy lifestyles, common emotional reactions to epidemics, coping strategies and warning signs. Peer participation is suggested as a support strategy, as well as spaces for social interaction that focus not only on academic aspects but also on leisure. Screening for mental symptoms is suggested through frequent submission of online forms or mobile applications. In addition to mental health, it is important to inquire about the degree of satisfaction of basic and technology-related needs. For b) the care of mental symptoms, one of the actions commonly identified was a consulting centre that can provide mental health care by telephone, by technology, and even in person -if required -, with permanent availability with rapid response teams for crisis situations, such as suicidal behavior and domestic violence. For c) pedagogical adaptations, fluent communication is an indispensable requirement; having clear instructions on academic activities can reduce uncertainty and therefore anxiety. The teaching and pedagogical staff at the institution can offer direct advice (via video calls or online group meetings) to provide support in study habits, degree-specific material and mental health. Conclusions: Included resources suggest the creation of a program that specifically addresses the mental health of students. This synthesis can provide guidelines that facilitate decision-making by the university, without losing sight of the fact that the institution and the student are immersed in a complex context, with circumstances and other actors at various levels that also intervene in mental health. Research is required on the evolution of the mental health situation and the effect of the actions that are being taken.

Cuidado de la salud mental del personal de salud durante COVID-19: recomendaciones basadas en evidencia y consenso de expertos / Mental Health Care of Health Workers During Covid-19: Recommendations Based on Evidence and Expert Consensus

RESUMEN Introducción: La situación de crisis generada por la COVID-19 y las medidas adoptadas han generado cambios sociales en las dinámicas normales de la población general y en especial para los trabajadores de la salud, que se encuentran en atención del paciente con infección sospechada o confirmada. Estudios recientes han detectado en ellos síntomas depresivos y ansiosos y síndrome de burnout, afecciones personales y sociales que alteran su capacidad de respuesta durante la emergencia sanitaria. El objetivo es generar recomendaciones de promoción y protección de la salud mental de los trabajadores y equipos de salud dispuestos como primera línea de atención en la emergencia sanitaria por COVID-19. Métodos: Se realizó una búsqueda rápida de literatura en PubMed y Google Scholar, y un consenso de expertos iterativo y mediante consulta electrónica, con 13 participantes de las áreas de psicología, psiquiatría y medicina; la gradación de su fuerza y direccionalidad se realizó según las normas internacionales del Joanna Briggs Institute. Resultados: Se generaron 31 recomendaciones sobre el autocuidado del trabajador de la salud, el cuidado comunitario entre los equipos de salud, el cribado de signos de alarma en salud mental y para las instituciones sanitarias. Conclusiones: Las actividades de promoción y protección en salud mental para el afrontamiento de la emergencia sanitaria generada por la COVID-19 en todo el mundo pueden abarcar acciones articuladas entre el trabajador, los equipos de salud y las instituciones sanitarias como parte de un cuidado integral, comunitario, corresponsable y sostenidas en el tiempo.

Risk Factors for Mortality in Colombian Patients with Candidemia.

The aim of the study was to describe the microbiology and susceptibility profile of candidemia and to identify the risk factors associated with mortality in Colombia. A cohort of patients was followed for 30 days during 2008 to 2010. Microbiological identification and susceptibility assessments were performed in a reference centre. Demographic, clinical and treatment variables were evaluated for their associations with mortality. A parametric survival regression analysis was used to identify the risk factors associated with mortality. A total of 109 patients with candidemia in four hospitals in Colombia were identified, with a median age of 30 years old. C. parapsilosis was the most frequently identified microorganism (38.5%); the susceptibility of all isolates was high to fluconazole and anidulafungin, except for C. glabrata isolates. The overall mortality was 35.7%, and the risk factors associated with mortality included lack of antifungal treatment (HR 5.5, 95% CI 3.6-11.4), cancer (HR 3.9, 95% CI 2.3-8.0), diabetes (HR 2.5, 95% CI 1.03-6.4), and age (HR 1.13 per every 10 years, 95% CI 1.02-1.24). Catheter removal was associated with a low mortality rate (HR 0.06, 95% CI 0.00-0.49). Prompt antifungal treatment, better glycemic control and catheter removal should be prioritized in the management of candidemia.

Effect of temperature and relative humidity on the stability of betalains encapsulated in cryogels from protein and polysaccharide.

The stability of betalains (Bet) encapsulated in cryogels made with a mixture of albumin (ALB) and albumin-pectin (ALB-PEC) as wall materials were evaluated during storage at 32% and 83% relative humidity (RH) at several different temperature conditions (4 °C, 30 °C and 40 °C). The retention of betalains (betanin + isobetanin) and phenolic compounds and the antioxidant activity were determined by high-performance liquid chromatography, the Folin-Ciocalteu method and radical ABTS*+ capture methodology. The color parameters and images of the encapsulated betalains were obtained. Cryogels prepared with ALB at 32% RH and at 4 °C provided betanin and isobetanin retention of 72% and 82%, with half-life times of 108 and 165 days, respectively. The antioxidant activity and phenolic compounds showed retention greater than 70% during storage at 32% RH at all temperatures. Cryogels prepared with ALB-PEC also conferred high retention percentages of phenolic compounds at 83% RH, but this high RH caused a significant decrease in the retention of betalains. Both ALB and ALB-PEC improved betalain stability during storage compared with the extracts without encapsulating. Therefore, cryogels could be used as protection matrices for betalains.

Genetic Variants Affecting Anti-VEGF Drug Response in Polypoidal Choroidal Vasculopathy Patients: A Systematic Review and Meta-Analysis.

Polypoidal choroidal vasculopathy (PCV) is usually regarded as a subtype of choroidal neovascularization (CNV) that is secondary to age-related macular degeneration (AMD) characterized by choroidal vessel branching, ending in polypoidal lesions. Despite their close association, PCV and neovascular AMD have shown differences, especially regarding patients' treatment response. Currently, antivascular endothelial growth factor (anti-VEGF) drugs, such as ranibizumab, bevacizumab and aflibercept, have demonstrated their efficacy in CNV patients. However, in PCV, anti-VEGF treatments have shown inconclusive results. Many genetic polymorphisms have been associated with a variable response in exudative/wet AMD patients. Thus, the aim of this study is to explore the genetic variants affecting anti-VEGF drug response in PCV patients. In this regard, we performed a systematic review and meta-analysis. We found four variants (CFH I62V, CFH Y402H, ARMS2 A69S, and HTRA1-62A/G) that have been significantly related to response. Among them, the ARMS2 A69S variant is assessed in our meta-analysis. In conclusion, in order to implement anti-VEGF pharmacogenetics in clinical routines, further studies should be performed, distinguishing physio-pathogenic circumstances between PCV and exudative AMD and the combined effect on treatment response of different genetic variants.

Analytical characterization of trace elements (zinc, copper, cadmium, lead and selenium) in saliva of pigs under common pathological conditions in the field: a pilot study.

BACKGROUND: This study is focused on the measurement of trace elements (zinc, copper, cadmium, lead and selenium) in the saliva of pigs in order to study their levels on different porcine pathological conditions in the field. The experiment involved 15 pigs without clinical signs of disease and 42 diseased pigs (suffering from lameness, rectal prolapse, fatigue or growth rate retardation). Individual saliva samples were collected, allowing the pigs to chew a sponge each for trace element quantifications through atomic absorption spectrometry (AAS). Since this is the first report on the measurements of trace elements in porcine saliva, a routine analytical validation study was performed for the quantification of all the studied elements. Moreover, the acute phase proteins C-reactive protein (CRP) and haptoblobin (Hp), the total antioxidant capacity (TAC) and adenosine deaminase (ADA) were quantified in the saliva samples for the animal's health status assessment. RESULTS: Modifications in the levels of acute phase proteins or ADA were only recorded in animals with lameness and rectal prolapse and those with fatigue respectively. Moreover, TAC level changes were observed in pigs with growth-rate retardation. However, alterations in the levels of two or more trace elements were reported for all the different groups of diseased pigs with evident variations within pathologies. CONCLUSIONS: The salivary quantification of trace elements could be considered as a complementary tool to acute phase proteins, TAC and ADA determinations for disease detection and differentiation in the pig and should be explored in greater depth.

Prevalence, Characteristics, and Association of Obstructive Sleep Apnea with Blood Pressure Control in Patients with Resistant Hypertension.

Rationale: Obstructive sleep apnea (OSA) is associated with poor blood pressure (BP) control and resistant hypertension (RH). Nevertheless, studies assessing its prevalence, characteristics, and association with BP control in patients with RH are limited.Objectives: The aim of this multicenter study was to assess the prevalence of OSA in a large cohort of subjects with RH and to evaluate the association of OSA with BP control.Methods: We recruited consecutive subjects with RH from three countries. A formal sleep test and blood pressure measurements, including 24-hour ambulatory blood pressure monitoring, were performed in all participants.Results: In total, 284 subjects with RH were included in the final analysis. Of these, 83.5% (95% confidence interval [CI], 78.7-87.3%) had OSA (apnea-hypopnea index ≥ 5 events/h); 31.7% (95% CI, 26.5-37.3%) had mild OSA, 25.7% (95% CI, 21-31.1%) had moderate OSA, and 26.1% (95% CI, 21.3-31.5%) had severe OSA. Patients with severe OSA had higher BP values than subjects with mild to moderate or no OSA. A greater effect was observed on the average nighttime BP, with an adjusted effect of 5.72 mm Hg (95% CI, 1.08-10.35 mm Hg) in severe OSA compared with participants without OSA. A dose-response association between the severity of OSA and BP values was observed. The prevalence of severe OSA was slightly higher in uncontrolled participants (adjusted odds ratio, 1.69; 95% CI, 0.97-2.99) but was not statistically significant.Conclusions: The present study confirms the high prevalence of OSA in participants with RH. Furthermore, it shows a dose-response association between OSA severity and BP measurements, especially in the nighttime.Clinical trial registered with www.clinicaltrials.gov (NCT03002558).

Phosphorylated ATM and H2AX in T and B lymphocytes from rats with moderate and severe malnutrition.

Protein calorie malnutrition (PCM) occurs when insufficient nutrients are consumed to satisfy the biological needs of an organism. The literature supports the relationship between malnutrition and DNA damage, and among the injuries to genetic material, DNA double-strand breaks (DSBs) are the most dangerous. This study aimed to determine whether the ability of splenic and peripheral blood T and B lymphocytes from nursing rats to recognize DSB-induced DNA damage is affected by PCM. Wistar strain rats were used, and experimental malnutrition was induced by creating food competition during lactation by increasing the number of offspring per wet nurse. Due to its high specificity, the phosphorylated H2AX variant histone assay associated with pATM (Ser1981) combined with flow cytometry was herein used to demonstrate the impact of malnutrition on the DNA damage response. Flow cytometry data indicated that splenic T and B lymphocytes from rats with severe PCM have the capacity to detect genetic material damage, as shown by an increased number of pATM + cells and altered signaling pathway continuity. Collectively, these data suggest that severe malnutrition compromises the continuity of the DNA damage response.

Porcine Breed, Sex, and Production Stage Influence the Levels of Health Status Biomarkers in Saliva Samples.

In this study, the influence of several factors such as breed, sex, and production stage over the normal range values of salivary biomarkers of health status was evaluated in pigs. A total of 409 pigs of 2 different breeds (conventional Large White × Duroc and Iberian pigs) were included in the study. Animals were divided into different groups according to their sex (male or female) and the stage of the production cycle they were in (post-weaning, nursery, fattening, and finishing). The levels of an inflammatory marker, adenosine deaminase (ADA), and two acute phase proteins, C-reactive protein (CRP) and haptoglobin (Hp) were measured in saliva samples. Moreover, the total antioxidant capacity level (TAC) was quantified for the first time in porcine saliva; therefore, an analytical validation and stability analysis during storage at -80°C were also performed. Differences according to breed were observed for all the markers studied; thus, the influence of age and sex on the normal range values were studied separately for conventional and Iberian pigs. In Large White × Duroc pigs the overall median values of ADA, CRP, Hp and TAC were 282 U/L, 10.49 ng/mL, 0.88 µg/mL, and 21.73 µM Trolox equivalents, respectively. However, higher values of inflammatory marker and acute phase proteins were observed in males at the initial stages of the production cycle, while females presented higher values when they had reached sexual maturity. In Iberian pigs the overall median values observed were 585 U/L, 4.81 ng/mL, 0.63 µg/mL, and 21.21 µM Trolox equivalents for ADA, CRP, Hp, and TAC respectively with slight differences in the influence of the studied factors. Sex differences were not observed in the levels of acute phase proteins in Iberian pigs, probably due to the castration of males during the first days of life; however, ADA levels were found to be higher in male pigs at the end of the production cycle. It could be concluded that breed, sex, and production stage influence the range values of salivary markers of health status in pigs and should be taken into account to further establish reference intervals.

Rationale and Methodology of the SARAH Trial: Long-Term Cardiovascular Outcomes in Patients With Resistant Hypertension and Obstructive Sleep Apnea / Justificación y metodología del ensayo clínico SARAH: evolución cardiovascular a largo plazo en pacientes con hipertensión resistente y apnea obstructiva del sueño

Introduction: Patients with resistant hypertension (RH) have a high risk of developing cardiovascular events; therefore, new therapeutic approaches to better control blood pressure may be useful in improving cardiovascular outcomes. The prevalence of obstructive sleep apnea (OSA) is very high among patients with RH. Continuous positive airway pressure (CPAP) has been shown to be an effective treatment for reducing blood pressure in patients with RH. Nevertheless, the long-term effect of CPAP treatment on cardiovascular outcomes has not been explored. The main objective of the SARAH study is to assess the impact of OSA and its treatment on cardiovascular outcomes (morbidity and mortality) in patients with RH. Methods: This study is a multi-center, prospective, observational cohort study. A total of 1371 patients with RH will be enrolled in the study and followed once a year for five years. At inclusion, ambulatory blood pressure monitoring (ABPM) and a sleep study will be performed in all subjects. Socio-demographic, clinical and cardiovascular variables will be collected at baseline and follow-up. Subsequently, subjects with OSA will be managed according to local standard practice. Based on the OSA diagnosis and its treatment, three cohorts of subjects with RH will be defined: non-OSA, treated OSA and non-treated OSA. Conclusions: This study will contribute to elucidating the long-term impact of OSA treatments on blood pressure control and cardiovascular outcomes in patients with RH. These results will contribute to improve the cardiovascular prognosis of patients with RH

Introducción: Los pacientes con hipertensión resistente (HR) tienen un elevado riesgo de desarrollar eventos cardiovasculares; así, las nuevas estrategias terapéuticas para el control de la presión arterial podrían ser útiles para mejorar los resultados cardiovasculares. La prevalencia de la apnea obstructiva del sueño (AOS) es muy elevada entre los pacientes con HR. Se ha demostrado que la presión positiva continua en la vía aérea (CPAP) constituye un tratamiento efectivo para reducir la presión arterial en pacientes con HR. Sin embargo, todavía no se han estudiado los efectos a largo plazo del tratamiento con CPAP sobre los resultados cardiovasculares. El principal objetivo del estudio SARAH es evaluar el impacto de la AOS y su tratamiento en los resultados cardiovasculares (morbilidad y mortalidad) en pacientes con HR. Métodos: Este es un estudio observacional prospectivo multicéntrico en el que se incluirán 1.371 pacientes con HR, a los cuales se les realizará seguimiento una vez al año durante 5 años. En el momento de la inclusión se realizará a todos los pacientes monitorización ambulatoria de la presión arterial (MAPA), así como un estudio de sueño. Se recogerán las variables sociodemográficas, clínicas y cardiovasculares tanto al inicio del estudio como durante el seguimiento. Posteriormente, los individuos con AOS serán tratados de acuerdo con la práctica clínica estándar de cada centro. Se definirán 3 grupos en función del diagnóstico de AOS y su tratamiento: sin AOS, con AOS en tratamiento, con AOS sin tratar. Conclusiones: Este estudio contribuirá a averiguar el impacto a largo plazo del tratamiento de la AOS en el control de la presión arterial y los resultados cardiovasculares en pacientes con HR. Asimismo, estos resultados contribuirán a mejorar el pronóstico cardiovascular de los pacientes con HR
