Predictive usefulness of qSOFA, NEWS and GYM scores in the elderly patient: EDEN-5 study.

OBJECTIVE: To analyze the prognostic accuracy of the scores NEWS, qSOFA, GYM used in hospital emergency department (ED) in the assessment of elderly patients who consult for an infectious disease. METHODS: Data from the EDEN (Emergency Department and Elderly Need) cohort were used. This retrospective cohort included all patients aged ≥65 years seen in 52 Spanish EDs during two weeks (from 1-4-2019 to 7-4-2019 and 30/3/2020 to 5/4/2020) with an infectious disease diagnosis in the emergency department. Demographic variables, demographic variables, comorbidities, Charlson and Barthel index and needed scores parameters were recorded. The predictive capacity for 30-day mortality of each scale was estimated by calculating the area under the receiver operating characteristic (ROC) curve, and sensitivity and specificity were calculated for different cut-off points. The primary outcome variable was 30-day mortality. RESULTS: 6054 patients were analyzed. Median age was 80 years (IQR 73-87) and 45.3% women. 993 (16,4%) patients died. NEWS score had better AUC than qSOFA (0.765, 95CI: 0.725-0.806, versus 0.700, 95%CI: 0.653-0.746; P < .001) and GYM (0.716, 95%CI: 0.675-0.758; P = .024), and there was no difference between qSOFA and GYM (P = .345). The highest sensitivity scores for 30-day mortality were GYM ≥ 1 point (85.4%) while the qSOFA score ≥2 points showed high specificity. In the case of the NEWS scale, the cut-off point ≥4 showed high sensitivity, while the cut-off point NEWS ≥ 8 showed high specificity. CONCLUSION: NEWS score showed the highest predictive capacity for 30-day mortality. GYM score ≥1 showed a great sensitivity, while qSOFA ≥2 scores provide the highest specificity but lower sensitivity.

Decalogue to promote the implementation and improvement of recommendations for the early diagnosis of HIV in Emergency Departments.

Early diagnosis of HIV is still a challenge. Emergency Departments (EDs) suppose ideal settings for the early detection of HIV, since patients with high prevalence of hidden HIV infection are frequently attending those services. In 2020, the Spanish Society of Emergency and Emergency Medicine (SEMES) published a series of recommendations for the early diagnosis of patients with suspected HIV infection and their referral and follow-up in the EDs as part of its "Deja tu huella" program. However, the application of these recommendations has been very heterogeneous in our country. Considering this, the working group of the HIV hospital network led by the SEMES has motivated the drafting of a decalogue, with the aim of promoting the implementation and improvement of protocols for the early diagnosis of HIV in Spanish EDs.

Recommendations for the early diagnosis of suspected human immunodeficiency virus infection in the emergency department and the referral of patients for follow-up: a consensus statement of the Spanish Society of Emergency Medicine (SEMES). / Recomendaciones dirigidas a los servicios de urgencias para el diagnóstico precoz de pacientes con sospecha de infección por VIH y su derivación para estudio y seguimiento.

Almost half of new diagnoses of human immunodeficiency virus (HIV) infection are made late, leading to increased morbidity and mortality, greater spread of infection, and higher public health care costs. Emergency services care for many patients who share behaviors associated with HIV transmission risk who arrive in clinical situations that are associated with HIV infection. A strategy to increase the rates of early diagnosis by promoting serology for HIV when caring for patients with certain clinical profiles might therefore be the key to improvement. This approach is hardly used at present, however, unless the result of serology would change the management of the acute complaint that led to the visit. These recommendations based on evidence from a search and review of recent publications were developed by a group of experts appointed by the Spanish Society of Emergency Medicine (SEMES). The resulting statement aims to support decision-making by emergency physicians and promote HIV screening and referral to appropriate specialists for follow-up in patients with certain conditions (sexually transmitted infections, herpes zoster, community-acquired pneumonia) or reporting certain scenarios (practice of chemsex, need for post-exposure prophylaxis). These 6 settings were selected because they are often seen in emergency departments and are common in patients with HIV-positive tests. The recommendations address when to order serology for HIV and how to manage the referral process. Included are decision-making tools for emergency physicians.

Casi la mitad de los nuevos diagnósticos de infección por el virus de la inmunodeficiencia humana (VIH) se realizan de forma tardía, lo cual provoca un aumento en la morbimortalidad, una mayor expansión de la epidemia y un incremento en los costes sanitarios públicos. En los servicios de urgencias se atiende a muchos de los pacientes que presentan situaciones indicadoras de infección por VIH o que comparten su misma vía de transmisión. Por lo tanto, pueden ser clave en una estrategia que mejore las tasas de diagnóstico precoz mediante la promoción de la solicitud de serologías frente al VIH durante la atención de determinados perfiles clínicos. Sin embargo, esto en la actualidad se produce escasamente a no ser que el resultado de la serología vaya a modificar el manejo del proceso agudo que ha motivado la consulta en urgencias. Las presentes recomendaciones se han desarrollado por un grupo de expertos designados por la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES) en base a la identificación y revisión de la evidencia científica más reciente. El objetivo de este documento es dar soporte a los médicos de urgencias en la toma de decisiones, promoviendo el cribado del VIH y la derivación de los pacientes al especialista adecuado para su seguimiento posterior en seis entidades clínicas seleccionadas por su elevada prevalencia en pacientes VIH positivos y la alta frecuencia con la que son atendidas en urgencias: 1) infecciones de transmisión sexual; 2) profilaxis post exposición; 3) herpes zoster; 4) práctica del chemsex; 5) neumonía adquirida en la comunidad, y 6) síndrome mononucleósico. Las recomendaciones incluyen indicaciones sobre en qué pacientes debe realizarse una serología, el proceso de derivación y herramientas para ayudar a los médicos de urgencias en la toma de decisiones.

Prognostic capability of the Maximum Acute Gastrointestinal Injury Score and of caloric intake in patients requiring vasopressors: A multicenter prospective cohort study.

PURPOSE: Our main objective was to use the Maximum Acute Gastrointestinal Injury Score (AGImax) to evaluate the prognostic capability of gastrointestinal dysfunction (GID), on hospital mortality in patients on mechanical ventilation (MV) requiring vasopressors. A secondary goal was to analyze the relationship between AGImax and vasopressor dosage with increasing caloric intake. MATERIALS AND METHODS: Prospective multicenter cohort study in ten ICUs across Argentina. Consecutive adult patients on MV, requiring vasopressors and receiving enteral nutrition (EN) were included. AGImax was identified (I-IV) using a modified AGI score. Comparisons of clinical and outcome variables were performed in 3 predetermined EN-groups: <10 kcal/kg/d, ≥10 to <20 kcal/kg/d, or ≥ 20 kcal/kg/d. RESULTS: A total of 494 patients met all inclusion criteria. Forty-four percent of patients had severe AGImax and 17% received <10 kcal/kg/day, indicating more severity and higher mortality. Notable independent predictors of mortality were AGImax, vasopressors, and caloric intake. PN was the only factor which had an inverse relationship to mortality. CONCLUSIONS: In this population, patients with AGImax III-IV were significantly associated with lower caloric intake and greater hospital mortality, highlighting the importance of AGI as a prognostic tool. As PN was linked with lower mortality, it could be an option to explore in further studies.

Displasia mesenquimal placentaria. Revisión placentaria / Placental mesenchymal dysplasia. Placental review

La displasia mesenquimal placentaria (DMP) es una anomalía cada vez más reconocible, que cursa con diversos signos, como placentomegalia, vasos tortuosos y vesículas quísticas en la placenta. Su repercusión sobre la madre y el recién nacido requiere una precisa valoración placentaria por parte de la matrona para el seguimiento de ambos. En el presente artículo se expone un caso clínico en el que la revisión pormenorizada de la placenta puso en marcha el correcto seguimiento de una madre y su recién nacido a partir del diagnóstico de DMP. La DMP es una entidad cuyo diagnóstico, aunque poco frecuente, no debe infraestimarse, dadas las repercusiones que pudiera tener tanto en la madre como en el desarrollo de su hijo. La revisión placentaria es una herramienta fundamental en el trabajo diario de la matrona. Esta práctica permite evitar sangrados e infecciones en el puerperio precoz e inmediato

Placental mesenchymal dysplasia (PMD) is an increasingly recognizable anomaly, with data such as placentomegaly, tortuous vessels and cystic vesicles in the placenta. Its repercussion on the mother and newborn makes the accurate placental assessment on the part of the matron is a necessary tool for the follow-up of both. This article presents a clinical case in which the detailed review of the placenta initiated the correct follow-up of a mother and her newborn due to the diagnosis of PMD. PMD is an entity that, although infrequent, should not be underestimated when it comes to diagnosing it, due to the repercussions it may have on both the mother and the development of her child. The placental revision is a fundamental tool in the daily work of the midwife. This practice allows bleeding and infection to be prevented in the early and immediate postpartum period

Reducing pressure ulcers in patients with prolonged acute mechanical ventilation: a quasi-experimental study. / Diminuição das úlceras por pressão em pacientes com ventilação mecânica aguda prolongada: um estudo quasi-experimental.

OBJECTIVE:: To determine the effectiveness of a quality management program in reducing the incidence and severity of pressure ulcers in critical care patients. METHODS:: This was a quasi-experimental, before-and-after study that was conducted in a medical-surgical intensive care unit. Consecutive patients who had received mechanical ventilation for ≥ 96 hours were included. A "Process Improvement" team designed a multifaceted interventional process that consisted of an educational session, a pressure ulcer checklist, a smartphone application for lesion monitoring and decision-making, and a "family prevention bundle". RESULTS:: Fifty-five patients were included in Pre-I group, and 69 were included in the Post-I group, and the incidence of pressure ulcers in these groups was 41 (75%) and 37 (54%), respectively. The median time for pressure ulcers to develop was 4.5 [4 - 5] days in the Pre-I group and 9 [6 - 20] days in the Post-I group after admission for each period. The incidence of advanced-grade pressure ulcers was 27 (49%) in the Pre-I group and 7 (10%) in the Post-I group, and finally, the presence of pressure ulcers at discharge was 38 (69%) and 18 (26%), respectively (p < 0.05 for all comparisons). Family participation totaled 9% in the Pre-I group and increased to 57% in the Post-I group (p < 0.05). A logistic regression model was used to analyze the predictors of advanced-grade pressure ulcers. The duration of mechanical ventilation and the presence of organ failure were positively associated with the development of pressure ulcers, while the multifaceted intervention program acted as a protective factor. CONCLUSION:: A quality program based on both a smartphone application and family participation can reduce the incidence and severity of pressure ulcers in patients on prolonged acute mechanical ventilation.

Stoppering/unstoppering of a rotaxane formed between an N-hetorycle ligand containing surfactant: ß-cyclodextrin pseudorotaxane and pentacyanoferrate(II) ions.

The assembly of a surfactant-based rotaxane by adding the labile aquopentacyanoferrate(II) ion to the previously formed pseudorotaxane between the surfactant 11-(isonicotinoyloxy)-N,N,N-triethyl-1-undecanaminium bromide and ß-cyclodextrin was investigated by 1H NMR and kinetic measurements. NMR spectroscopy has showed that the rotaxane can be formed through two different mechanisms. The rotaxane can be unstoppered by using the pyridine ligand substitution reaction by the high-field cyanide ligand. In this work a new method is developed for the preparation of several new surfactant-based rotaxanes by changing the hydrophilic and hydrophobic regions of the surfactants and the nature of the macrocycle.

Diminuição das úlceras por pressão em pacientes com ventilação mecânica aguda prolongada: um estudo quasi-experimental / Reducing pressure ulcers in patients with prolonged acute mechanical ventilation: a quasi-experimental study

RESUMO Objetivo: Determinar a eficácia de um programa de gestão da qualidade para reduzir a incidência e a gravidade de úlceras por pressão em pacientes de terapia intensiva. Métodos: Estudo com metodologia quasi-experimental, antes-e-depois, conduzido em uma unidade de terapia intensiva clínica e cirúrgica. Incluíram-se os pacientes consecutivos que receberam ventilação mecânica por um período igual ou superior a 96 horas. Uma equipe de Melhoria de Processos delineou um processo de intervenção multifacetado, que consistiu de uma sessão educacional, uma lista de verificação de úlcera de pressão, um aplicativo para smartphone para monitoramento de lesões e um conjunto de normas de tomada de decisão, além de prevenção familiar. Resultados: O Grupo Pré-I incluiu 25 pacientes, e o Grupo Pós-I foi constituído por 69 pacientes. A incidência de úlcera de pressão nestes grupos foi de 41 (75%) e 37 (54%), respectivamente. O tempo mediano para o desenvolvimento das úlceras por pressão foi de 4,5 (4-5) dias no Grupo Pré-I e 9 (6-20) dias no Grupo Pós-I após a admissão para cada um dos períodos. A incidência de úlceras por pressão de grau avançado foi de 27 (49%) no Grupo Pré-I e 7 (10%) no Grupo Pós-I. A presença de úlceras por pressão na alta foi de 38 (69%) e 18 (26%), respectivamente, para os Grupos Pré-I e Pós-I (p < 0,05 para todas as comparações). A participação da família totalizou 9% no Grupo Pré-I e aumentou para 57% no Grupo Pós-I (p < 0,05). Utilizou-se um modelo de regressão logística para analisar os preditores de úlcera de pressão com grau avançado. A duração da ventilação mecânica e a presença de falência de órgão associaram-se positivamente com o desenvolvimento de úlceras por pressão, enquanto o programa multifacetado de intervenção atuou como fator de proteção. Conclusão: Um programa de qualidade, com base em um aplicativo para smartphone e na participação da família, pode reduzir a incidência e a gravidade de úlceras por pressão em pacientes com ventilação mecânica aguda prolongada.

La homocisteinemia materna como factor asociado al aborto espontáneo / Maternal homocysteinemia as a factor associated with spontaneous abortion

Introducción. Dentro del concepto de «trombofilia» se agrupan una serie de trastornos hereditarios y/o genéticos del sistema coagulativo capaces de aumentar el riesgo de aborto de repetición. La hiperhomocisteinemia, incluida en este grupo, constituye una de las entidades mejor conocidas. Objetivos. Los objetivos del presente estudio son explorar la asociación de la homocisteinemia materna con el aborto espontáneo (repetido o no), establecer la prevalencia de hiperhomocisteinemia entre las pacientes abortadoras y determinar el efecto que la suplementación preconcepcional y prenatal con folatos y vitamina B12 ejerce sobre la homocisteinemia. Material y métodos. Estudio de casos y controles con apareamiento 1:1 por edad y antecedentes de aborto. Se determinó en todas ellas la homocisteinemia en ayunas, así como aquellas variables que podrían modificarla. Resultados y conclusión. La homocisteinemia es significativamente mayor en abortadoras que en controles, aunque la tasa de pacientes hiperhomocisteinémicas en la serie es muy baja. Los datos sugieren un escaso papel terapéutico para los folatos y la vitamina B12 (AU)

Introduction. The concept of "thrombophilia" encompasses a group of genetic and/or inherited disorders of the coagulative system able to increase the risk of recurrent spontaneous abortion. Hyperhomocysteinemia, an entity included in this group, is one of the best known. Objectives. Our objectives were to explore the association between maternal homocysteinemia and spontaneous (recurrent or isolated) abortion, establish the prevalence of hyperhomocysteinemia among patients with abortion, and determine the effect of preconceptional and prenatal supplementation with folate and vitamin B12 on homocysteinemia. Matherial and methods. We performed a case-control study with 1:1 matching based on maternal age and previous abortions. In all participants, fasting homocysteine levels, as well as the factors that could modify them, were determined. Results and conclusions. Homocysteine concentrations were significantly higher in women with abortion than in controls, although the rate of hyperhomocysteinemia in the series was very low. The data do not suggest an important therapeutic role for folates or vitamin B12 in these patients(AU)

Stability and photodynamics of lumichrome structures in water at different pHs and in chemical and biological caging media.

We report on photophysical studies of lumichrome (Lc) in water at different pHs, and interacting with the human serum albumin (HSA) protein and ß-cyclodextrin (ß-CD) in neutral aqueous solutions. We used steady-state and picosecond time-resolved emission spectroscopy to investigate the structural changes of Lc at the ground and excited states, as well as the rotational dynamics of the complexes with HSA and ß-CD. In neutral water, the predominant neutral alloxazine-type structure of Lc coexists with a small population of the anionic form. In the presence of HSA, we observed an increase in the absorption band intensity at 450 nm. This increase is due to a preferential complexation (1:1 stoichiometry, K=8600 M(-1)) of the Lc anion structures within the protein. This change is not observed when ß-CD is added, in which the Lc neutral form is exclusively complexed, giving a 1:1 stoichiometry. The fluorescence lifetimes of Lc in neutral water solutions are 4.2 and 2.3 ns, assigned to anionic and neutral alloxazinic forms, respectively. Using ß-CD, the lifetime of the 1:1 complexes is 0.74 ns, while in the case of HSA complexes we observed two lifetimes (0.83 and 0.14 ns), which we explained in terms of different interactions of the anions with the protein. The rotational relaxation time of free Lc in neutral water is 75 ps. For Lc:ß-CD complexes this time is 0.44 ns, in full agreement with the expected value from the hydrodynamic theory. For HSA solutions, we obtained a distribution of values between ∼1 and 4.5 ns, suggesting a site heterogeneity of complexation and a different strength of binding for the involved Lc anionic forms. Our results give information about the different photorelaxation behavior of Lc within chemical and biological cavities, and might help in a better design of nanosystems for drug carriers and delivery.

Microheterogeneous catalysis.

The catalytic effect of micelles, polymers (such as DNA, polypeptides) and nanoparticles, saturable receptors (cyclodextrins and calixarenes) and more complex systems (mixing some of the above mentioned catalysts) have been reviewed. In these microheterogeneous systems the observed changes in the rate constants have been rationalized using the Pseudophase Model. This model produces equations that can be derived from the Brönsted equation, which is the basis for a more general formulation of catalytic effects, including electrocatalysis. When, in the catalyzed reaction one of the reactants is in the excited state, the applicability (at least formally) of the Pseudophase Model occurs only in two limiting situations: the lifetime of the fluorophore and the distributions of the quencher and the probe are the main properties that define the different situations.

Stirring up the mud: using a community-based participatory approach to address health disparities through a faith-based initiative.

This case study provides a mid-course assessment of the Bronx Health REACH faith-based initiative four years into its implementation. The study uses qualitative methods to identify lessons learned and to reflect on the benefits and challenges of using a community-based participatory approach for the development and evaluation of a faith-based program designed to address health disparities. Key findings concern the role of pastoral leadership, the importance of providing a religious context for health promotion and health equality messages, the challenges of creating a bilingual/bi-cultural program, and the need to provide management support to the lay program coordinators. The study also identifies lessons learned about community-based evaluation and the importance of addressing community concern about the balance between evaluation and program. Finally, the study identifies the challenges that lie ahead, including issues of program institutionalization and sustainability.
