Norovirus infection as a model of chronic or recurrent infection in common variable immunodeficiency.

Common variable immunodeficiency (CVID) is the most frequent symptomatic primary immunodeficiency (PID) in general population. PID are genetic diseases that share a dysfunction in the immune system entailing a greater risk of both chronic and recurrent infections. These patients can also develop chronic gastrointestinal infections caused by norovirus with persistent viral dissemination, which can be detected months after primoinfection. Additionally, a proportion of CVID patients show a typical severe enteropathy presenting with recurrent diarrhoea, intestinal malabsorption, inflammatory lesions, and villous atrophy. Some studies have related this enteropathy with chronic intestinal infection caused by norovirus.

Schwannoma de plexo braquial y toxina botulínica: a propósito de un caso / Brachial plexus schwannoma and botulinum toxin: a case report

Los schwannomas de plexo braquial son tumoraciones desarrolladas a partir de las vainas neurales de rara presentación, pero evolución benigna. Pueden ocasionar clínica, generalmente de tipo neuropático, por crecimiento local con el consiguiente efecto compresivo de estructuras neurales nobles como las raíces del plexo braquial. La toxina botulínica es una neurotoxina sintetizada por la bacteria clostridium botulinum. Su mecanismo de acción consiste en bloquear selectivamente los receptores colinérgicos de la unión neuromuscular, produciendo una parálisis neuromuscular temporal y reversible, recuperando la función en aproximadamente tres a seis meses. Presentamos el caso de un paciente diagnosticado de schwannoma de plexo braquial con efecto compresivo creciente, a quien se le plantea tratamiento con toxina botulínica en los músculos escalenos.(AU)

Brachial plexus schwannomas are tumors developed from the neural sheaths of rare presentation, but benign evolution. They can cause symptoms, generally of the neuropathic type, due to local growth with the consequent compressive effect of noble neural structures such as the roots of the brachial plexus. Botulinum toxin is a neurotoxin synthesized by the bacterium Clostridium Botulinum. Its mechanism of action consists of selectively blocking the cholinergic receptors of the neuromuscular junction, producing a temporary and reversible neuromuscular paralysis, recovering function in approximately three to six months. We present the case of a patient diagnosed with brachial plexus schwannoma with increasing compre­ssive effect who was treated with botulinum toxin in the scalene muscles.(AU)

Pointing Out Some Issues Regarding Reproduction Management in Murciano-Granadina Goats.

Two of the most important problems in high-yielding dairy goat farms are early and accurate pregnancy diagnosis and the appropriate dry off of lactating does before the next kidding. The hypothesis posits that it could be possible to identify pregnant does through maximum progesterone milk levels at any time during the pregnancy, and that there is an optimal time to apply a lactation inhibitor to help dry off lactating does. Therefore, 114 Murciano-Granadina breed goats were used, from which 74 goats were inseminated at week 20 of lactation and samples of milk from pregnant and non-pregnant goats were taken at two-week intervals. The average maximum progesterone milk levels were higher outside the natural breeding season (40° latitude) than in the breeding season (11.6 ± 1.13 vs. 8.6 ± 1.02 ng/mL), although the levels from pregnant and non-pregnant goats were similar (10.85 ± 1.3 vs. 9.74 ± 1.6 ng/mL), except in the case of pregnancy with four foetuses (12.5 ± 1.3 ng/mL). Milk yield at mating does not affect fertility until a value of at least 3250 mL/day. Pregnancy started to affect milk yield up to the +7th week and was 59.9% lower in the +10th week after mating, so the use of lactation inhibitors could be more effective from this latter week. In conclusion, the results show that it is not possible to detect gestation in goats reliably through the maximum concentration of progesterone in milk at any time during lactation, except in the case of goats gestating four foetuses, that the milk yield of goats at mating does not affect fertility until a value of at least 3250 mL/day, and that from the 10th week post-mating, the application of lactation inhibitors would be optimal.

Consensus on basic conduct during the hospital admission of patients with acute heart failure.

Acute heart failure (AHF) is a highly prevalent clinical entity in individuals older than 45 years in Spain. AHF is associated with significant morbidity and mortality and is the leading cause of hospitalisation for individuals older than 65 years in Spain, a quarter of whom die within 1 year of the hospitalisation. In recent years, there has been an upwards trend in hospitalisations for AHF, which increased 76.7% from 2003 to 2013. Readmissions at 30 days for AHF have also increased (from 17.6% to 22.1%), at a relative mean rate of 1.36% per year, with the consequent increase in the use of resources and the economic burden for the healthcare system. The aim of this document (developed by the Heart Failure and Atrial Fibrillation Group of the Spanish Society of Internal Medicine) is to guide specialists on the most important aspects of treatment and follow-up for patients with AHF during hospitalisation and the subsequent follow-up. The main recommendations listed in this document are as follows: 1) At admission, perform a comprehensive assessment, considering the patient's standard treatment and comorbidities, given that these determine the disease prognosis to a considerable measure. 2) During the first few hours of hospital care, decongestive treatment is a priority, and a staged diuretic therapeutic approach based on the patient's response is recommended. 3) To manage patients in the stable phase, consider starting and/or adjusting evidence-based drug treatment (e.g., sacubitril/valsartan or angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, beta blockers and aldosterone antagonists). 4) At hospital discharge, use a checklist to optimise the patient's management and identify the most efficient options for maintaining continuity of care after discharge.

Consenso de actuación básica durante el ingreso hospitalario por insuficiencia cardiaca aguda / Consensus on basic conduct during the hospital admission of patients with acute heart failure

La insuficiencia cardiaca aguda (ICA) es una entidad clínica con una elevada prevalencia en la población de más de 45años en España. Está asociada a una importante morbimortalidad, constituyendo la primera causa de hospitalización en mayores de 65años en nuestro país, de los cuales una cuarta parte fallecen al año del ingreso. En los últimos años se ha observado una tendencia al alza en las hospitalizaciones por ICA, que aumentaron un 76,7% en el período de 2003 a 2013. Los reingresos a los 30días por ICA también aumentaron (del 17,6 al 22,1%) a un ritmo medio relativo del 1,36% por año, con el consiguiente incremento en el uso de recursos y en la carga económica para el sistema sanitario. Este documento, elaborado por el grupo de Insuficiencia Cardiaca y Fibrilación Auricular de la Sociedad Española de Medicina Interna, tiene como objetivo orientar al especialista en los aspectos más importantes del tratamiento y seguimiento de los pacientes con ICA durante el ingreso y el seguimiento posterior. Las principales recomendaciones recogidas son: 1)en el momento del ingreso, realizar una evaluación integral, considerando el tratamiento habitual y comorbilidades del paciente, ya que condicionan en gran medida el pronóstico de la enfermedad; 2)en las primeras horas de atención hospitalaria, el tratamiento descongestivo es prioritario y se recomienda un abordaje terapéutico diurético escalonado en función de la respuesta; 3)en el manejo de la fase estable, considerar el inicio y/o ajustar el tratamiento con fármacos basados en la evidencia, es decir, sacubitrilo/valsartán o IECA/ARAII, betabloqueantes y antialdosterónicos; 4)en el momento del alta hospitalaria, utilizar un checklist para optimizar el manejo del paciente hospitalizado e identificar las opciones más eficientes para mantener la continuidad de cuidados tras el alta (AU)

Enhancing the Capacity of Local Health Departments to Address Birth Equity: The Institute for Equity in Birth Outcomes.

INTRODUCTION: Significant and persistent racial and ethnic disparities exist related to infant mortality and other birth outcomes. Few models exist that aim to prepare organizations to implement essential features, such as community engagement or intervening on social determinants of health. METHODS: Between 2013 and 2015, teams from seven local health departments participated in the Institute for Equity in Birth Outcomes (EI) with the goals of building capacity and implementing changes to address equity in birth outcomes. Four of the teams enrolled in the first cohort (2013-2015), and three enrolled in cohort two (2014-2015). To examine the EI effort and its impact on capacity and implementation of changes, two types of assessments were completed. Capacities of the teams in specific key areas were assessed using "Best Change Process" instruments at the completion of participation in the EI. Teams also documented on an ongoing basis implementation of interventions. The data were analyzed using descriptive statistics and Pearson Correlation tests. RESULTS: Best Change Process capacity scores were higher in the first cohort than in the second and were highly correlated with implementation of changes (Pearson's Correlation = 0.838, p = 0.037). Collectively, the teams implemented about 32 new programs, policies, practices, and systems changes aimed at addressing equity in birth outcomes. Most interventions were based on scientific recommendations and local epidemiologic data. DISCUSSION: The results of the study suggest the EI is a promising approach that may result in strong capacity and ability to implement interventions aimed at addressing equity in birth outcomes.

Causas de muerte fetal: Un revisión de 38 pacientes / Causes associated to fetal death: A review study of 38 women

INTRODUCCIÓN: La pérdida del embarazo que ocurre tras las veinte semanas de gestación, se denomina muerte fetal (MF); es un evento que causa un gran impacto psicoemocional en la pareja afectada. La literatura médica afirma que, en casi la mitad de estos casos, no hay una causa conocida. Las causas principales están relacionadas son: síndrome antifosfolípido obstétrico (SAF), otras alteraciones inmunológicas (OIA), otros factores que pueden causar infarto placentario por coagulación, rotura prematura de membranas, preeclampsia y trombosis en la circulación útero-placentaria. MÉTODOS: Revisamos cuidadosamente la historia clínica y los estudios inmunológicos de una cohorte de 38 pacientes que han sufrido MF. RESULTADOS: Treinta y ocho pacientes (edades 36-42 años) fueron estudiadas. En más de la mitad de los pacientes (57 %) se diagnosticó SAF. El hipotiroidismo autoinmune (26 %), el anticuerpo antinuclear (24 %) comprendió el grupo de OIA. Once de 38 pacientes mostraron diferentes mutaciones de trombofilias. La hiperhomocisteinemia estuvo presente en el 53 % de los pacientes. CONCLUSIÓN: Las alteraciones inmunológicas y la trombofilia se asociaron con una proporción significativa de nuestros casos de MF. El diagnóstico de las causas evitables es necesario para evitar complicaciones obstétricas en embarazos futuros

INTRODUCTION: Pregnancy loss that occurs after the twenty weeks of gestation, termed foetal death (FD), is a rare event of pregnancy causing great psycho-emotional impact on the affected couple. Medical literature states that in nearly half of these cases, there is no known cause. Leading, causes are related to obstetric antiphospholipid syndrome (APS), other immunological alterations (OIA), other factors that may cause clotting placental infarction, premature rupture of membranes, preeclampsia, and thrombosis in the utero-placental circulation with subsequent FD. METHODS: We carefully reviewed the complete medical records and immunological studies of a cohort of 38 patients that have suffered FD. RESULTS: Thirty-eight patients (ages 36 - 42 years) were studied. In more than half of the patients (57%) APS was diagnosed. Autoimmune hypothyroidism (26%), antinuclear antibody (24%) comprised the group of OIA. Eleven out of 38 patients showed different thrombophilia mutations. Hyperhomocysteinemia was present in 53% of patients. CONCLUSION: Immunological alterations and thrombophilia were associated with a significant proportion of our FD cases. Diagnosis of preventable causes of FD is necessary in order to avoid any obstetric complications in future pregnancies

Prevalencia de hipertrigliceridemia en adultos y factores cardiometabólicos asociados. Estudio SIMETAP-HTG / Prevalence of hypertriglyceridemia in adults and related cardiometabolic factors. SIMETAP-HTG study

OBJETIVO: Determinar en la población adulta las tasas de prevalencia brutas y ajustadas por edad y sexo de hipertrigliceridemia (HTG) y valorar su asociación con factores de riesgo cardiovascular, enfermedad renal crónica y enfermedades cardiovasculares y cardiometabólicas. MÉTODOS: Estudio observacional transversal realizado en Atención Primaria, con 6.588 sujetos de estudio adultos, seleccionados aleatoriamente con base poblacional. Los pacientes tenían HTG si la concentración de triglicéridos era≥150mg/dL (≥1,7mmol/L) o estaban en tratamiento hipolipidemiante para reducir los triglicéridos. Se valoraron las asociaciones mediante análisis univariado y multivariante, y se determinaron las prevalencias brutas y ajustadas por edad y sexo. RESULTADOS: Las medias aritméticas y geométricas de las concentraciones de triglicéridos fueron respectivamente 120,5 y 104,2mg/dL en la población global, 135,7 y 116,0mg/dL en hombres, y 108,6 y 95,7mg/dL en mujeres. Las prevalencias brutas de HTG fueron 29,6% en población global, 36,9% en hombres y 23,8% en mujeres. Las prevalencias ajustadas por edad y sexo de HTG fueron 27,0% en población global, 34,6% en hombres y 21,4% en mujeres. Las variables independientes que más se asociaban con la HTG fueron hipercolesterolemia (OR: 4,6), c-HDL bajo (OR: 4,1), esteatosis hepática (OR: 2,8), diabetes (OR: 2,0) y obesidad (OR: 1,9). CONCLUSIONES: Las medias de triglicéridos y las prevalencias de HTG se encuentran intermedias entre las de otros estudios nacionales e internacionales. La quinta parte de la población adulta femenina y más de un tercio de la masculina presentaba HTG. Los factores independientes asociados con HTG fueron hipercolesterolemia y c-HDL bajo, y las variables cardiometabólicas diabetes, esteatosis hepática y obesidad

AIM: To determine in the adult population the crude and the sex- and age-adjusted prevalence rates of hypertriglyceridaemia (HTG) and to assess its association with cardiovascular risk factors, chronic kidney disease, cardiovascular and cardiometabolic diseases. METHODS: Cross-sectional observational study conducted in Primary Care, with 6,588 adult study subjects, randomly selected on base-population. Patients had HTG if the triglyceride level was≥150mg/dL (≥1.7mmol/L), or were on lipid-lowering therapy to lower triglyceride. Associations were assessed by univariate and multivariate analysis, and crude and sex- and age-adjusted prevalence rates were determined. RESULTS: The arithmetic and geometric means of triglyceride levels were respectively 120.5 and 104.2mg/dL in global population, 135.7 and 116.0mg/dL in men, and 108.6 and 95.7mg/dL in women. The crude HTG prevalence rates were 29.6% in global population, 36.9% in men and 23.8% in women. The sex- and age-adjusted HTG prevalence rates were 27.0% in global population, 34.6% in men and 21.4% in women. The independent variables that were most associated with HTG were hypercholesterolemia (OR: 4.6), low HDL-C (OR: 4.1), hepatic steatosis (OR: 2.8), diabetes (OR: 2.0), and obesity (OR: 1.9). CONCLUSIONS: The means of triglyceride levels and HTG prevalence rates are intermediate between those of other national and international studies. A fifth of the female adult population and more than a third of the male population had HTG. The independent factors associated with HTG were hypercholesterolemia and low HDL-C, and the cardiometabolic variables diabetes, hepatic steatosis and obesity

Influence functions for a hysteretic deformable mirror with a high-density 2D array of actuators.

We present modeling and analysis of a hysteretic deformable mirror where the facesheet interacts with a continuous layer of piezoelectric material that can be actuated distributively by a matrix of electrodes through multiplexing. Moreover, a method to calculate the actuator influence functions is described considering the particular arrangement of electrodes. The results are presented in a semi-analytical model to describe the facesheet's deformation caused by a high-density array of actuators, and validated in a simulation. The proposed modeling of an interconnection layout of electrodes is used to determine the optimal pressures the actuators must exert to achieve a desired surface deformation.

Ethanolic extract of Artemisia campestris subsp. glutinosa (Besser) Batt. inhibits HIV-1 replication in vitro through the activity of terpenes and flavonoids on viral entry and NF-κB pathway.

ETHNO-PHARMACOLOGICAL RELEVANCE: The genus Artemisia spp. is well known for its anti-infectious properties and its high content in anti-infectious compounds, like the well-known sweet wormwood (Artemisia annua L.). Another Artemisia species, Artemisia campestris subsp. glutinosa (Besser) Batt., field wormwood, has been traditionally used as medicinal plant in the Mediterranean region. AIM OF THE STUDY: The aim of this study is to investigate the anti-HIV activity of field wormwood, to identify the compounds responsible for this activity and their structure and mechanism of action. MATERIALS AND METHODS: Antiviral activity of isolated compounds and extracts was evaluated in HIV-1 infections of lymphoblastoid cells. We also evaluated the mechanism of action of isolated compounds. Viral entry was studied comparing the inhibitory effect of isolated compounds on wild type HIV-1 and VSV pseudotyped HIV-1. To assess the viral transcriptional effect, plasmids encoding luciferase reporter genes under the control of the whole genome of HIV-1 or NF-κB or Sp1 transcription factors were transfected in the presence of the compounds under evaluation. Finally, antioxidant activity was assessed by quantitation of reduced and total glutathione in treated cell cultures. RESULTS: Ethanolic and aqueous extracts of Artemisia campestris subsp. glutinosa (Besser) Batt. subsp. glutinosa displayed anti-HIV activity in vitro, although ethanolic extract was more powerful (IC50 14.62 µg/mL). Bio-guided ethanolic extract fractionation leads to the isolation and characterization of two terpenes, damsin and canrenone, and four flavonoids, 6, 2', 4'-trimethoxyflavone, acerosin, cardamonin and xanthomicrol. All the isolated compounds inhibited HIV-1 replication in vitro with IC50 values between the middle nanomolar and the low micromolar range. Their anti-HIV mechanism of action is due to the bloking of viral entry and/or transcription inhibition, without correlation with the antioxidant activity, through interference with the cellular transcription factors NF-κB and Sp1, which are targets that are not currently reached by antiretroviral therapy. CONCLUSION: We describe here the anti-HIV activity of field wormwood, Artemisia campestris subsp. glutinosa (Besser) Batt., and the isolation and study of the mechanism of action of two terpenes and four flavonoids, responsible, at least in part, for its activity, through the inhibition of two different cellular targets affecting the HIV replication cycle. The activity of these compounds in cellular targets could explain why plant extracts can be used in the treatment of different diseases. Besides, the presence of several compounds with dual and different mechanisms of action could prove useful in the treatment of HIV-1 infection, since it could aid to overcome drug resistances and simplify drug therapy. This work is a further step in understanding the anti-infectious activity of wormwood species and their use in treating infectious diseases.

Neoadjuvant chemotherapy in locally advanced colon cancer: a systematic review.

BACKGROUND: Preoperative or neoadjuvant chemotherapy (NAC) has emerged as a novel alternative to treat locally advanced colon cancer (LACC), as in other gastrointestinal malignancies. However, evidence of its efficacy and safety has not yet been gathered in the literature. The aim of the present study was to perform an extensive review of the scientific evidence for NAC in patients with LACC. METHODS: PubMed, EMBASE, MEDLINE and Cochrane Library were searched for a systematic review of the literature from 2010 to 2019. Six eligible studies were included, with a total of 27,937 patients, 1232 of them (4.4%) treated with NAC. There were only one randomized controlled trial, three phase II non-randomized single arm studies and two retrospective studies. RESULTS: The baseline computed tomography scan showed that most of patients had a T3 tumor. The completion rate of the planned neoadjuvant treatment ranged from 52.5 to 93.8%. Between 97.2 and 100% of patients had the scheduled surgery. The median tumor volume reduction after NAC ranged from 62.5 to 63.7%. The anastomotic leak rate in the NAC group ranged from 0 to 7%, with no cases of postoperative mortality. There was major pathological tumor regression in 4-34.7% of cases. Between 84 and 100% of NAC patients had R0-surgery. Survival after NAC seems to be encouraging although significant improvement has only been proven in T4b tumours. CONCLUSIONS: According to our systematic review, the NAC may be a safe and effective emerging therapeutic alternative for treating LACC. This approach, which is still being tested, increases the reliance on accurate radiological staging.

Methods: This is a descriptive study on 270 adult, pediatric, and neonatal patients in critical status. The TISS-28, and nursing and patient sociodemographic instruments were used. A descriptive statistical analysis using the sociodemographic and work-related variables was carried out. Bi-variate analysis and logistic regression were calculated in order to analyze the nursing performance by levels of complexity. Results: The interventions provided by the nursing staff in the internal medicine service in Grade II is 9.8 times more than in the rest of the patients, grade III increases by 68 times when the patient has an excess hospital stay. Discussion: Patients in the intensive care or surgical services require more care. Conclusion: The TISS-28 offers an estimate on the evolution and attention time required by patients in critical status as well as the corresponding ideal nurse-patient ratios.

RESUMO Introdução: Atualmente as intervenções terapêuticas são mais especializadas e complexas, identificou-se que o Therapeutic Intervention Scoring System-28 (TISS-28) é um instrumento adequado para planejar as atividades de enfermagem. Objetivo: Determinar mediante a aplicação do instrumento TISS-28, o grau de complexidade das intervenções realizadas na assistência de cuidados de enfermagem a pacientes em estado crítico. Métodos: Estudo descritivo, 270 pacientes (adultos, pediátricos e neonatais) em estado crítico; foi coletada informação sociodemográfica tanto do pessoal de enfermagem quanto dos pacientes através de um instrumento, aplicou-se o TISS-28 para identificar o grau de complexidade das intervenções que foram prestadas ao paciente. A análise estatística foi descritiva para variáveis sociodemográficas e laborais; a análise bivariada e a regressão logística foi utilizada para as ações realizadas por enfermagem mediante níveis de graus de complexidade. Resultados: As intervenções realizadas pela equipe de enfermagem no serviço de clínica médica do Grau II são 9,8 vezes mais do que no restante dos pacientes, o grau III aumenta em 68 vezes quando o paciente tem um tempo de internação excessivo. Discussão: Os pacientes que se encontram nos serviços de cuidados intensivos ou cirúrgicos requerem maiores cuidados. Conclusão: O TISS-28 permite prever do estado do paciente crítico e sua evolução. Determina o tempo de atenção requerido conforme a gravidade deste, aliás facilita a atribuição idónea de enfermeira-paciente.
