Efficacy of an asynchronous telerehabilitation program in post-COVID-19 patients: A protocol for a pilot randomized controlled trial

Background: About 40% of patients who have had COVID-19 still have symptoms three months later whereas a 10% may experience physical and/or psychological consequences two years later. Therefore, it is necessary to perform preventive interventions when patients are discharged from the hospital to decrease the aforementioned sequelae. The purpose of this pilot-controlled trial will be to determine the efficacy of a rehabilitation program on functional status and psychosocial factors for post-COVID-19 patients when it is delivered through a tele-care platform versus a booklet-based rehabilitation. Methods: The estimated sample size will be of 50 participants who have been discharged after COVID-19 and have a level of fatigue equal or greater than 4 on the Fatigue Severity Scale. The primary outcome will be the severity of fatigue. Participants will be randomly allocated to an "asynchronous telerehabilitation group"or to a "booklet-based rehabilitation group". Treatment in both groups will be the same and will consist of a combination of therapeutic exercise and an educative program. Treatment outcomes will be evaluated the last day of the intervention and at three- and six-months follow-up. Discussion: The telerehabilitation intervention appears to be a viable and efficacy option in decreasing severe fatigue and other fitness variables such as strength and aerobic capacity, similar to other traditional rehabilitation formats such as through an explanatory booklet

Evolución de la conductividad en la Albufera de Valencia entre 1985 y 2018

La laguna costera de la Albufera de Valencia es una masa de agua oligohalina rodeada de un antiguo marjal, transformado en cultivo del arroz desde hace más de 200 años. La presión de las aportaciones superficiales mantiene la conductividad en valores estables en torno a la media anual, modificada puntualmente al alza sólo en los periodos de sequía. La concentración de cloruros es la variable más relacionada con la conductividad. En el estudio de la serie temporal se observa que en el último decenio hay una tendencia significativa al aumento de los valores mínimos de la conductividad, lo cual indicaría una disminución de la cantidad de agua dulce que llega a la laguna. La medida de esa variable sería un buen indicador de las alteraciones que se pueden producir en un escenario previsible de cambio climático con descenso de las precipitaciones y de las aportaciones de agua dulce

Sensibilidad de microorganismos gramnegativos de infecciones intraabdominales y evolución de los aislados con ß-lactamasas de espectro extendido en el estudio smart en españa (2002-2010)

Introducción. El estudio SMART (Study for Monitoring Antimicrobial Resistance Trends) tiene como objetivo monitorizar la sensibilidad a los antimicrobianos de los microorganismos gramnegativos aislados en la infección intraabdominal, con especial seguimiento de los que producen β-lactamasas de espectro extendido (BLEE). Material y métodos. Se han analizado por microdulución los datos de sensibilidad de 8.869 aislados recogidos en el estudio SMART en España entre 2002 y 2010 en el que han participado 16 centros. Resultados. Escherichia coli fue el patógeno más frecuente (60,9% en la infección intraabdominal adquirida en la comunidad y 49,9% en la nosocomial) seguido de Klebsiella pneumoniae (8,9% vs 9,2%). Pseudomonas aeruginosa fue más habitual en la infección nosocomial (5,6% comunitaria y 8,6% nosocomial). La frecuencia de aislados con BLEE fue: E. coli 8,7%, K. pneumoniae 8,4%, Klebsiella oxytoca 1,4% y Proteus mirabilis 1,6%. En los pacientes de mayor edad aumentó la proporción global de aislados con BLEE (6,8% en pacientes >60 años). Ertapenem y meropenem fueron los antimicrobianos más activos en el conjunto de las enterobacterias (rango de sensibilidad con criterios EUCAST, 89-100%) y también entre los aislados con BLEE (95,5-100%). La actividad de amoxicilina/ácido clavulánico y piperacilina/tazobactam fue considerablemente inferior, en particular en los aislados con BLEE. Ertapenem mantuvo una buena actividad (sensibilidad >95%) en los productores de BLEE resistentes a amoxicilina/ácido clavulánico, piperacilina/tazobactam o fluoroquinolonas. Conclusiones. Los datos de sensibilidad del estudio SMART en España avalan las guías terapéuticas actuales de infección intraabdominal que sitúan al ertapenem como tratamiento empírico de elección, teniendo en cuenta sobre todo la elevada frecuencia de aislados con BLEE en nuestro medio. Introduction. The SMART (Study for Monitoring Antimicrobial Resistance Trends) surveillance study records the antimicrobial susceptibility of Gram-negative bacilli obtain from intraabdominal infections with special focus in isolates with extended spectrum ß-lactamases (ESBLs). Material and Methods. The antimicrobial susceptibility of 8,869 isolates was analyzed by microdilution during the SMART study performed in Spain from 2002 to 2010. Isolates were recovered in 16 centres. Results. Escherichia coli was the most prevalent pathogen (60.9% from intraabdominal infections acquired in the community and 49.9% in those from nosocomial origin) followed by Klebsiella pneumoniae (8.9% vs 9.2%). Pseudomonas aeruginosa was more common in intraabdominal infections from nosocomial origin (5.6% community and 8.6% nosocomial). Frequency of ESBL-producing isolates was: E. coli, 8.7%; K. pneumoniae, 8.4%; Klebsiella oxytoca, 1.4%; and Proteus mirabilis, 1.6%. Overall, ESBL-producing isolates were more frequently isolated from elderly patients (6.8% >60 years). Ertapenem and meropenem were the most active antimicrobials (susceptibility range with EUCAST criteria, 89.0-100%) when considering all Enterobacteriaceae isolates and also against ESBL producers (95.5-100%). Susceptibility of amoxicillin/clavulanic acid and piperacillin/tazobactam was lower, particularly among ESBL-producing isolates. Nevertheless, ertapenem maintained a good activity (susceptibility >95%) in ESBL-producers that were resistant to amoxicillin/clavulanic acid, piperacillin/tazobactam or fluoroquinolones. Conclusions. Antimicrobial susceptibility data from the SMART-Spain study reinforce current therapeutic guidelines of intraabdominal infections that include ertapenem as the empirical choice for treatment. This is also supported by the high frequency of ESBL-producers in our geographic area

Recommendations of the Spanish Antibiogram Committee (COESANT) for selecting antimicrobial agents and concentrations for in vitro susceptibility studies using automated systems

Automated antimicrobial susceptibility testing devices are widely implemented in clinical microbiology laboratories in Spain, mainly using EUCAST (European Committee on Antimicrobial Susceptibility Testing) breakpoints. In 2007, a group of experts published recommendations for including antimicrobial agents and selecting concentrations in these systems. Under the patronage of the Spanish Antibiogram Committee (Comité Español del Antibiograma, COESANT) and the Study Group on Mechanisms of Action and Resistance to Antimicrobial Agents (GEMARA) from the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), and aligned with the Spanish National Plan against Antimicrobial Resistance (PRAN), a group of experts have updated this document. The main modifications from the previous version comprise the inclusion of new antimicrobial agents, adaptation of the ranges of concentrations to cover the EUCAST breakpoints and epidemiological cut-off values (ECOFFs), and the inference of new resistance mechanisms. This proposal should be considered by different manufacturers and users when designing new panels or cards. In addition, recommendations for selective reporting are also included. With this approach, the implementation of EUCAST breakpoints will be easier, increasing the quality of antimicrobial susceptibility testing data and their microbiological interpretation. It will also benefit epidemiological surveillance studies as well as the clinical use of antimicrobials aligned with antimicrobial stewardship programs

Ebola: translational science considerations

We are currently in the midst of the most aggressive and fulminating outbreak of Ebola-related disease, commonly referred to as “Ebola”, ever recorded. In less than a year, the Ebola virus (EBOV, Zaire ebolavirus species) has infected over 10,000 people, indiscriminately of gender or age, with a fatality rate of about 50%. Whereas at its onset this Ebola outbreak was limited to three countries in West Africa (Guinea, where it was first reported in late March 2014, Liberia, where it has been most rampant in its capital city, Monrovia and other metropolitan cities, and Sierra Leone), cases were later reported in Nigeria, Mali and Senegal, as well as in Western Europe (i.e., Madrid, Spain) and the US (i.e., Dallas, Texas; New York City) by late October 2014. World and US health agencies declared that the current Ebola virus disease (EVD) outbreak has a strong likelihood of growing exponentially across the world before an effective vaccine, treatment or cure can be developed, tested, validated and distributed widely. In the meantime, the spread of the disease may rapidly evolve from an epidemics to a full-blown pandemic. The scientific and healthcare communities actively research and define an emerging kaleidoscope of knowledge about critical translational research parameters, including the virology of EBOV, the molecular biomarkers of the pathological manifestations of EVD, putative central nervous system involvement in EVD, and the cellular immune surveillance to EBOV, patient-centered anthropological and societal parameters of EVD, as well as translational effectiveness about novel putative patient-targeted vaccine and pharmaceutical interventions, which hold strong promise, if not hope, to curb this and future Ebola outbreaks. This work reviews and discusses the principal known facts about EBOV and EVD, and certain among the most interesting ongoing or future avenues of research in the field, including vaccination programs for the wild animal vectors of the virus and the disease from global translational science perspective

Design, construction and operation of the ProtoDUNE-SP Liquid Argon TPC

The ProtoDUNE-SP detector is a single-phase liquid argon time projection chamber (LArTPC) that was constructed and operated in the CERN North Area at the end of the H4 beamline. This detector is a prototype for the first far detector module of the Deep Underground Neutrino Experiment (DUNE), which will be constructed at the Sandford Underground Research Facility (SURF) in Lead, South Dakota, USA. The ProtoDUNE-SP detector incorporates full-size components as designed for DUNE and has an active volume of $7\times 6\times 7.2$~m$^3$. The H4 beam delivers incident particles with well-measured momenta and high-purity particle identification. ProtoDUNE-SP's successful operation between 2018 and 2020 demonstrates the effectiveness of the single-phase far detector design. This paper describes the design, construction, assembly and operation of the detector components

Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Percutaneous electrical nerve stimulation versus dry needling: Effectiveness in the treatment of chronic low back pain

Objetivo: El objetivo de este estudio fue evaluar la efectividad del tratamiento de los puntos gatillo miofasciales [PG] con punción seca [ND] en comparación con la estimulación nerviosa eléctrica percutánea [PENS]. Método: En este ensayo clínico, se trataron 122 sujetos que padecían dolor lumbar crónico inespecífico [CLBP]. Se distribuyeron aleatoriamente en dos grupos de tratamiento: uno que tomó PENS y el otro que tomó DN de PG en los músculos paraespinales lumbares profundos [multífido lumbar], cuadrado lumbar y glúteo medio. Se midieron cuatro variables: dolor percibido y calidad del sueño mediante una escala visual analógica [EVA], umbral de tolerancia al dolor por presión en los PG con un algómetro y calidad de vida evaluada con el índice de discapacidad de Oswestry. Resultados: Se encontró al menos un PG en todos los pacientes, más comúnmente situado en el músculo cuadrado lumbar [97,6 por ciento]. La mejora conseguida para ambos grupos de tratamiento fue similar en todas las variables medidas, aunque el grupo DN realizó menos sesiones que el grupo PENS. Conclusiones: Se podría concluir que la efectividad de la DN es comparable a la del PENS y, por tanto, puede considerarse como otra herramienta útil y con efectos adversos limitados dentro del abordaje multidisciplinar requerido en el manejo del CLBP inespecífico. Objective: The aim of this study was to evaluate the effectiveness of treating myofascial trigger points [TrPs] with dry needling [DN] compared to percutaneous electrical nerve stimulation [PENS]. Method: In this clinical trial, 122 subjects suffering from non-specific chronic low back pain [CLBP] were treated. They were randomly distributed into two treatment groups: one taking PENS and the other taking DN of TrPs on the deep lumbar paraspinal muscles [lumbar multifidi], quadratus lumborum, and gluteus medius. Four variables were measured: perceived pain and sleep quality using a visual analog scale [VAS], pressure-pain tolerance threshold on TrPs with an algometer, and quality of life assessed with the Oswestry Disability Index. Results: At least one TrP was found in all patients, most commonly situated in the quadratus lumborum muscle [97.6 percent]. The improvement achieved for both treatment groups was similar in all the measured variables, although the DN group carried out fewer sessions than the PENS group. Conclusions: It could be concluded that the effectiveness of DN is comparable to that of PENS and, therefore, it may be considered as another useful tool with limited adverse effects within the multidisciplinary approach required in the management of non-specific CLBP
