Validation of the Adolescent Dating Violence Victim-Blaming Attitudes Scale.

Dating violence (DV) is a social problem that affects adolescents worldwide. Prevalence figures show that this type of violence is starting at an increasingly younger age, which is why it is important to study attitudes toward DV, as they are an important risk factor. Victim-blaming attitudes justify this type of violence by excusing perpetrators and blaming victims. The present study aimed to validate an instrument developed to assess victim-blaming attitudes in DV cases among the adolescent population: The Adolescent Dating Violence Victim-Blaming Attitudes Scale (ADV-VBA). Two samples of high school students were recruited using a two-stage stratified sampling by conglomerates, one consisting of 758 adolescents (48% females) and the other of 160 (50% females), whose ages ranged from 12 to 18 years. We found that this instrument presented good reliability and validity evidence, showing good internal consistency, a clear one-factor latent structure, and a close relation to other related constructs, such as ambivalent sexism and perpetration and victimization of DV. We also found that items did not present differential item functioning across gender and the instrument was especially informative for assessing moderate to high levels of victim-blaming attitudes. A short five-item version is also presented for use when time and space constraints exist. Our results indicate that the ADV-VBA scale is a psychometrically sound measure to assess victim-blaming attitudes in cases of adolescent DV.

Association of Muscle Strength, Psychological Factors, and Central Sensitization With Movement-Evoked Pain in Patients With Nonspecific Chronic Low Back Pain: The BACKFIT Project.

BACKGROUND: People with chronic pain might evade certain movements to prevent their experience of pain. Movement-evoked pain (MEP) might induce lower functionality during daily activities. HYPOTHESIS: (1) MEP after physical fitness tests would vary depending on the main musculature involved in the test; (2) physical and psychological factors would be associated with MEP in patients with NSCLBP. STUDY DESIGN: Cross-sectional design. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 104 (69 women) patients aged 51.0 ± 10.3 years with NSCLBP participated. MEP was measured with a visual analog scale (VAS) at baseline and immediately after performing each physical fitness test, that is, the Biering-Sørensen, prone bridging, handgrip, chair-stand, and 8-foot time-up-and-go tests, measuring back extensor, back flexor, upper- and lower-body muscle strength, and motor agility, respectively. Global muscle strength was calculated with normalized index (z-score) procedure. Depression, anxiety, pain catastrophizing, and central sensitization were assessed with the Beck Depression Inventory II, State Trait Anxiety Inventory I, Pain Catastrophizing Scale, and Central Sensitization Inventory (CSI), respectively. RESULTS: Patients showed greater pain after completion of the Biering-Sørensen (mean difference 95% CI, 0.02, 1.11), prone bridging (0.15, 1.21), lower pain after handgrip (-1.46, -0.52), and the 8-foot time-up-and-go (-1.43, 0.46) tests (all P ≤ 0.04). Lower global muscular strength (ß between -0.18 and -0.30), and greater pain catastrophizing (ß = 0.16), and CSI scoring (ß between 0.18 and 0.27) were associated with greater MEP (all P ≤ 0.04). CONCLUSION: Greater MEP was observed after tests measuring core musculature strength than after tests measuring distal (limbs) strength and agility. Greater MEP was overall associated with lower muscle strength, greater pain catastrophizing, and central sensitization. CLINICAL RELEVANCE: Fitness testing might be implemented as a complementary tool for the monitoring of NSCLBP in clinical settings.

Association of Moderate-to-Vigorous Physical Activity, Sedentary Time, Fat Percentage, and Physical Fitness with Gait Parameters in Women with Fibromyalgia: The Al-Ándalus Project.

Gait impairments have been found in women with fibromyalgia, reducing the physical activity possibilities in this population and leading to a negative correlation with fibromyalgia impact. The aim of this study was to analyze the individual and independent associations of moderate-to-vigorous physical activity (MVPA), sedentary time, fat percentage, and physical fitness with gait parameters in women with fibromyalgia. A total of 84 women with fibromyalgia were included. MVPA and sedentary time were assessed with accelerometry, fat percentage with bioimpedance analysis, and physical fitness with field-based fitness tests. Gait was assessed during a "6 min walk test" and categorized in velocity, cadence, step length, step cycle duration, unipedal stance phase, and bipedal stance phase. Individual relationships were analyzed by partial correlations and independent relationships by linear regressions, adjusting by age and height. MVPA, sedentary time, fat percentage, and physical fitness were correlated with most gait parameters (rpartial between |0.842| and |0.219|; p ≤ 0.05). Physical fitness was independently associated with all gait parameters (ß between |0.346| and |0.761|; p ≤ 0.002). In addition, MVPA was independently associated with velocity and step length (ß = 0.241 and 0.292; both p = 0.004), and fat percentage was associated with bipedal stance phase (ß = 0.242; p = 0.049). Good levels of MVPA, physical fitness, and adequate weight balance are associated with improved gait parameters in women with fibromyalgia.

Identifying Adolescents at Risk for Emotional Disorders with Latent Profile Analysis: A Personalized, Transdiagnostic Preventive Intervention.

It can be challenging to assign patients to the appropriate intervention programs, as risk and protective factors for developing emotional disorders are multiple and shared across disorders. This study aimed to provide a theoretical and empirical approach to identify and categorise adolescents into different levels of severity. The risk of developing emotional symptoms was assessed in 1425 Spanish adolescents (M = 14.34, SD = 1.76; 59.9% women). Latent Profile Analysis (LPA) was conducted to identify subgroups based on their emotional symptom severity, risk, and resilience factors. Results revealed four profiles: at low risk (emotionally healthy), moderate risk (for selective interventions), high risk (for indicated interventions), and severe risk (for clinical referral). Older age and especially female gender were predictors of higher risk clusters, and there were differences in the levels of psychopathology and health-related quality of life across clusters. Identification of at-risk adolescents for emotional disorders by means of LPA may contribute to designing personalised and tailored prevention programs that match adolescents' specific needs.

Compositional and functional analysis of the bacterial community of Mediterranean Leptosols under livestock grazing.

The composition and functioning of soil bacterial communities, as well as their responses to multiple perturbations, are not well understood in the terrestrial ecosystems. Our study focuses on the bacterial community of erosive and poorly developed soils (Haplic Leptosols) in Mediterranean rangelands of Extremadura (W Spain) with different grazing intensities. Leptosols from similar natural conditions were selected and sampled at two depths to determine the soil properties as well as the structure and activity of bacterial communities. As grazing intensified, the soil C and N content increased, as did the number and diversity of bacteria, mainly of fast-growing lineages. Aridibacter, Acidobacteria Gp6 and Gp10, Gemmatimonas, and Segetibacter increased their abundance along the grazing-intensity gradient. Firmicutes such as Romboutsia and Turicibacter from livestock microbiome also increased. In functional terms, the KEGG pathways enriched in the soils with moderate and high grazing intensity were ABC transporters, DNA repair and recombination proteins, the two-component system, and the degradation of xenobiotics. All of these proved to be related to stronger cell division and response mechanisms to environmental stressors such as drought, warming, toxic substances, and nutrient deprivation. Consequently, the bacterial community was affected by grazing, but appeared to adapt and counteract the effects of a high grazing intensity. Therefore, a clearly detrimental effect of grazing was not detected in the bacterial community of the soils studied.

Fiber-optic spectrum monitoring of wavelength-division-multiplexed telecommunication signals with MHz update rates.

We propose a novel (to our knowledge) and simple real-time optical monitoring (RTOM) system for dynamic spectral analysis of telecommunication signals, involving electro-optic (EO) temporal sampling followed by dispersion-induced frequency-to-time mapping and high-speed photodetection. This system enables tracking of the presence and relative intensity of multiple wavelength-division-multiplexed (WDM) data streams that span over a broad frequency band with high resolution, accuracy, and fast measurement update rates. We derive the design conditions and trade-offs of the proposed scheme and report proof-of-concept experiments and a numerical result that demonstrate successful spectral monitoring of dense-WDM signals with different modulation formats and bit rates, over the full C-band, with the needed resolution to discern channels separated by a few tens of GHz, and with an unprecedented fast measurement update rate in the MHz range.

The Perceived Severity of Adolescent Dating Violence (PS-ADV) Scale: A Validation Study / Escala de Percepción de la Gravedad de la Violencia en el Noviazgo en Adolescentes: un estudio de validación

Objectives: Dating violence is a widespread social problem with increasing prevalence among adolescents. The perceived severity of dating violence is an important factor related to key aspects of this type of violence, such as acceptability, justification, attitudes toward intervention, and victims’ willingness to seek help. The aim of this study was to validate an instrument to assess the perceived severity of dating violence in a sample of adolescents: the Perceived Severity of Adolescent Dating Violence (PS-ADV) scale. Method: Two groups of high school students, one with 621 adolescents (47.2% females) and another with 300 (50% females), aged 13-18 years were selected by a two-stage stratified sampling procedure. Results: The results indicated that the PS-ADV scale has excellent internal consistency (α = .89) and a clear one-factor latent structure (CFI = .96, TLI = .94, RMSEA [90% CI] = .074 [.062, .087]). For validity, the PS-ADV scores were related negatively to victim-blaming attitudes and ambivalent sexism (hostile and benevolent sexism), and positively to empathy (empathic concern, perspective taking, fantasy). Conclusions: This study provides evidence that the PS-ADV scale is a psychometrically sound measure for assessing the perceived severity of dating violence among adolescents. (AU)

Objetivos: La violencia en el noviazgo es un problema social generalizado con una prevalencia cada vez mayor entre los adolescentes. La gravedad percibida de la violencia en el noviazgo es un factor importante relacionado con aspectos clave de este tipo de violencia, como la aceptabilidad, la justificación, las actitudes hacia la intervención y la disposición de las víctimas a buscar ayuda. El objetivo de este estudio fue validar un instrumento para evaluar la gravedad percibida de la violencia en el noviazgo en una muestra de adolescentes: la escala de Percepción de la Gravedad de la Violencia en el Noviazgo en Adolescentes (PS-ADV). Método: Se seleccionaron dos grupos de estudiantes de secundaria, uno con 621 adolescentes (47.2% mujeres) y otro con 300 (50% mujeres), en edades comprendidas entre los 13 y los 18 años, mediante un procedimiento de muestreo estratificado en dos etapas. Resultados: Los resultados indicaron que la escala PS-ADV tiene una excelente consistencia interna (α = .89) y una clara estructura latente de un factor (CFI = .96, TLI = .94, RMSEA [90% CI] = .074 [.062, .087]). En cuanto a la validez, las puntuaciones del PS-ADV se relacionaron negativamente con las actitudes de culpabilización de la víctima y el sexismo ambivalente (sexismo hostil y benevolente) y positivamente con la empatía (preocupación empática, toma de perspectiva, fantasía). Conclusiones: El estudio demuestra que la escala PS-ADV es una medida psicométricamente sólida para evaluar la gravedad percibida de la violencia en el noviazgo entre los adolescentes. (AU)

Kinematic parameters related to functional capacity, fatigue, and breathlessness during the 6-min walk test in older adults with heart failure with preserved ejection fraction.

AIMS: This paper aims to assess kinematic parameters related to functional capacity, fatigue, and breathlessness during the 6-min walk test (6MWT) in patients with heart failure with preserved ejection fraction (HFpEF). METHODS AND RESULTS: A cross-sectional study was conducted in which adults 70 years or older with HFpEF were voluntarily recruited between April 2019 and March 2020. An inertial sensor was placed at the L3-L4 level and another on the sternum to assess kinematic parameters. The 6MWT was divided into two 3-min phases. Leg fatigue and breathlessness, assessed by the Borg scale, the heart rate (HR), and the oxygen saturation (SpO2), were measured at the beginning and the end of the 6MWT. The difference in kinematic parameters between the 6MWT two 3-min phases was also calculated. Bivariate Pearson correlations and subsequent multivariate linear regression analysis were performed. Seventy older adults with HFpEF (mean = 80.74 years old) were included. Kinematic parameters explained 81.00% of the functional capacity, 45.50% of the leg fatigue and 66.10% of the breathlessness variance. Moreover, kinematic parameters could explain 30.90% of the SpO2 variance at the end of the 6MWT. Kinematic parameters also explained 33.10% of the SpO2 difference between the beginning and end of 6MWT. Kinematic parameters explained neither the HR variance at the end of 6MWT nor the HR difference between the beginning and end. CONCLUSION: Gait kinematics from L3-L4 and sternum explain a part of the variance in subjective outcomes, assessed by the Borg scale, and objective outcomes such as functional capacity and SpO2. The kinematic assessment allows clinicians to quantify fatigue and breathlessness through objective parameters related to the patient's functional capacity.

Role of proton pump inhibitors dosage and duration in Helicobacter pylori eradication treatment: Results from the European Registry on H. pylori management.

BACKGROUND: Management of Helicobacter pylori (H. pylori) infection requires co-treatment with proton pump inhibitors (PPIs) and the use of antibiotics to achieve successful eradication. AIM: To evaluate the role of dosage of PPIs and the duration of therapy in the effectiveness of H. pylori eradication treatments based on the 'European Registry on Helicobacter pylori management' (Hp-EuReg). METHODS: Hp-EuReg is a multicentre, prospective, non-interventionist, international registry on the routine clinical practice of H. pylori management by European gastroenterologists. All infected adult patients were systematically registered from 2013 to 2022. RESULTS: Overall, 36,579 patients from five countries with more than 1000 patients were analysed. Optimal (≥90%) first-line-modified intention-to-treat effectiveness was achieved with the following treatments: (1) 14-day therapies with clarithromycin-amoxicillin-bismuth and metronidazole-tetracycline-bismuth, both independently of the PPI dose prescribed; (2) All 10-day (except 10-day standard triple therapy) and 14-day therapies with high-dose PPIs; and (3) 10-day quadruple therapies with clarithromycin-amoxicillin-bismuth, metronidazole-tetracycline-bismuth, and clarithromycin-amoxicillin-metronidazole (sequential), all with standard-dose PPIs. In first-line treatment, optimal effectiveness was obtained with high-dose PPIs in all 14-day treatments, in 10- and 14-day bismuth quadruple therapies and in 10-day sequential with standard-dose PPIs. Optimal second-line effectiveness was achieved with (1) metronidazole-tetracycline-bismuth quadruple therapy for 14- and 10 days with standard and high-dose PPIs, respectively; and (2) levofloxacin-amoxicillin triple therapy for 14 days with high-dose PPIs. None of the 7-day therapies in both treatment lines achieved optimal effectiveness. CONCLUSIONS: We recommend, in first-line treatment, the use of high-dose PPIs in 14-day triple therapy and in 10-or 14-day quadruple concomitant therapy in first-line treatment, while standard-dose PPIs would be sufficient in 10-day bismuth quadruple therapies. On the other hand, in second-line treatment, high-dose PPIs would be more beneficial in 14-day triple therapy with levofloxacin and amoxicillin or in 10-day bismuth quadruple therapy either as a three-in-one single capsule or in the traditional scheme.

Effectiveness of Mepolizumab in Patients with Severe Eosinophilic Asthma with/without Nasal Polyposis: A Real-Life Study.

INTRODUCTION: Asthma is one of the most common chronic diseases and affects around 334 million people worldwide. The estimated prevalence of severe asthma is 3-10% of the asthmatic population. Mepolizumab has demonstrated efficacy in reducing exacerbations, oral corticosteroid use, and improving quality of life, asthma control, and lung function in patients with severe eosinophilic asthma (SEA). Our study aimed to check the response to mepolizumab in a series of severe asthma patients regarding exacerbations, oral corticosteroid use, asthma control, quality of life, and lung function and to compare the response between patients with and without nasal polyps. METHOD: This is a retrospective, multicenter study of RE-ASGRAMUR (Register of Severe Asthma of the Region of Murcia) performed in eight hospitals of the Region of Murcia (Spain) under routine clinical practice conditions. We included patients diagnosed with SEA who completed at least 1 year of treatment with mepolizumab. We analyzed clinical characteristics, drug tolerance, and effectiveness: exacerbations, ACT, miniAQLQ, forced expiratory volume in 1 s (FEV1), and use of oral corticosteroids. We also compared the results between patients with and without nasal polyps. RESULTS: The median of exacerbations before treatment was 3 and decreased to 0 after treatment (mean decrease of 77.4%). The median diary oral prednisone intake was 15 mg before treatment and 5 mg after treatment (mean 56% reduction). We have obtained a significant improvement in other variables: ED visits and hospitalizations, asthma control (ACT), quality of life (miniAQLQ), and lung function (FEV1). Thirty-four out of 70 patients (48.57%) fulfilled the criteria of super-responder, and 17 out of 70 (24.29%) had a complete response. More patients in the group with nasal polyps fulfilled the criteria of super-responder and complete response to mepolizumab. CONCLUSIONS: Mepolizumab is a safe and effective treatment for SEA patients, improving exacerbations, oral corticosteroid intake, asthma control, quality of life, and lung function. In patients with associated nasal polyposis, there is a statistically significant higher proportion of super-responders and complete responders.

Effectiveness of Helicobacter pylori Treatments According to Antibiotic Resistance.

INTRODUCTION: Antibiotic resistance is one of the main factors that determine the efficacy of treatments to eradicate Helicobacter pylori infection. Our aim was to evaluate the effectiveness of first-line and rescue treatments against H. pylori in Europe according to antibiotics resistance. METHODS: Prospective, multicenter, international registry on the management of H. pylori (European Registry on H. pylori Management). All infected and culture-diagnosed adult patients registered in the Spanish Association of Gastroenterology-Research Electronic Data Capture from 2013 to 2021 were included. RESULTS: A total of 2,852 naive patients with culture results were analyzed. Resistance to clarithromycin, metronidazole, and quinolones was 22%, 27%, and 18%, respectively. The most effective treatment, regardless of resistance, were the 3-in-1 single capsule with bismuth, metronidazole, and tetracycline (91%) and the quadruple with bismuth, offering optimal cure rates even in the presence of bacterial resistance to clarithromycin or metronidazole. The concomitant regimen with tinidazole achieved an eradication rate of 99% (90/91) vs 84% (90/107) with metronidazole. Triple schedules, sequential, or concomitant regimen with metronidazole did not achieve optimal results. A total of 1,118 non-naive patients were analyzed. Resistance to clarithromycin, metronidazole, and quinolones was 49%, 41%, and 24%, respectively. The 3-in-1 single capsule (87%) and the triple therapy with levofloxacin (85%) were the only ones that provided encouraging results. DISCUSSION: In regions where the antibiotic resistance rate of H. pylori is high, eradication treatment with the 3-in-1 single capsule, the quadruple with bismuth, and concomitant with tinidazole are the best options in naive patients. In non-naive patients, the 3-in-1 single capsule and the triple therapy with levofloxacin provided encouraging results.

Evolución a largo plazo y factores influyentes de los pacientes que ingresan con FANV en los servicios de Medicina Interna de Galicia / Long-term evolution and influential factors of patients admitted with NVAF in the Internal Medicine services of Galicia

Objectives: The objective of this study was to investigate the longterm evolution and influencing factors of patients with non-valvular atrial fibrillation (NVAF) admitted to internal medicine services. Patients and method: This is an observational and retrospective study of the evolution during five years of the patients admitted, between January-2016 and January-2017, with FANV in the Galician Internal Medicine services. For this end, it was quantified the emergency room visits, hospital admissions and survival. The factors with more influence over these variables were studied. Results: It was included 1.342 patients and followed for 5 years. There were 3.691 hospital admissions, and 8.687 visits to the emergency department (ED). They had a survival of 66,6%, with a median survival of 1.034,57 days. The univariate analysis found that age, antithrombotic treatment at discharge and Barthel's index influenced survival, but not sex. However, in the multivariate analysis only Barthel’s index was found to be independent variable that influence survival. Conclusions: Patients with NVAF admitted to internal medicine services constitute a subpopulation at high risk of hospital readmission and visits to the ED. A change in the model of transition to discharge and outpatient follow-up is necessary, through adapted proactive programs, capable of reducing hospital events and improving the quality of life of these patients and their caregivers. (AU)

Objetivos: Estudiar la evolución a lo largo plazo, así como los factores que influyen en la misma, de la población con fibrilación auricular no valvular (FANV) que ingresa en los servicios de Medicina Interna. Pacientes y método: Estudio observacional y retrospectivo de la evolución durante cinco años, de los pacientes ingresados con FANV en los servicios de Medicina Interna gallegos, entre enero-2016 y enero-2017. Para este fin se cuantificaron las visitas a urgencias, los ingresos hospitalarios y la supervivencia. Se estudiaron los factores que más influyeron en estas variables. Resultados: Se incluyeron 1.342 pacientes y se realizó un seguimiento durante 5 años. Se contabilizaron 3.691 ingresos hospitalarios, y 8.687 visitas al servicio de urgencias (SU). Tuvieron una supervivencia del 66,6%, con una mediana de supervivencia de 1.034,57 días. En el análisis univariante, la edad, el tratamiento antitrombótico al alta y el índice de Barthel influyeron en la supervivencia, no así el sexo. En el análisis multivariante, el índice de Barthel fue la única variable independiente que influyó en la supervivencia. Conclusiones: Los pacientes con FANV ingresados en los servicios de Medicina Interna, suponen una subpoblación de alto riesgo de reingreso hospitalario y visitas al SU. Es necesario un cambio en el modelo de transición al alta y de seguimiento ambulatorio, mediante programas proactivos adaptados, capaces de reducir eventos hospitalarios y mejorar la calidad de vida de estos pacientes y sus cuidadores.

Validación de la escala de gravedad percibida de la violencia de pareja contra la mujer en población ecuatoriana

Introducción: La violencia de pareja contra la mujer (VPM) es un problema de salud pública a nivel global cuya prevalencia en Ecuador es de las más elevadas de Latinoamérica. La gravedad percibida de la VPM influye en las actitudes públicas hacia la VPM, como la aceptabilidad, el sentido de responsabilidad personal o la disposición a intervenir en casos de VPM. Método: En este estudio se presenta la adaptación de la escala española de gravedad percibida de la VPM (PS-IPVAW) al contexto cultural ecuatoriano, en una muestra de 652 participantes. Resultados: Los resultados mostraron que la escala PS-IPVAW tiene una buena consistencia interna, que sus ítems tienen una baja carga de deseabilidad social, que es invariante entre géneros y que se relaciona con la culpabilidad a la víctima, la aceptabilidad de la VPM y el sexismo hostil. Discusión: La escala PS-IPVAW es un instrumento con suficientes evidencias de fiabilidad y validez para evaluar la gravedad percibida de la VPM en Ecuador y representa un importante aporte para mejorar las estrategias de prevención, intervención y erradicación de este tipo de violencia en el contexto ecuatoriano.

Introduction: Intimate partner violence against women (IPVAW) is a global public health problem whose prevalence in Ecuador is among the highest in Latin America. The perceived severity of IPV influences public attitudes toward IPVAW, such as acceptability, sense of personal responsibility, or willingness to intervene in cases of IPV. Method: This study presents the adaptation of the Spanish scale of perceived severity of IPVAW (PS-IPVAW) to the Ecuadorian cultural context, in a sample of 652 participants. Results: Our results showed that the PS-IPVAW scale has good internal consistency, its items presented low loadings of social desirability, that it is invariant across genders and that it is related to victim blaming, acceptability of IPV and hostile sexism. Discussion: The PS-IPVAW scale showed adequate evidence.

A 12-Month Follow-Up of PROCARE+, a Transdiagnostic, Selective, Preventive Intervention for Adolescents At-Risk for Emotional Disorders.

Few studies have reported long-term follow-up data on selective preventive interventions for adolescents. No follow-up selective preventive transdiagnostic studies for adolescents at-risk for emotional disorders, such as anxiety and depression, have been reported. To fill this gap, this study aims to provide the first follow-up assessment of a randomized controlled trial (RCT) studying selective transdiagnostic prevention in at-risk adolescents. A 12-month follow-up assessment was conducted with subjects who originally received either PROCARE (Preventive transdiagnostic intervention for Adolescents at Risk for Emotional disorders), PROCARE+, which includes the PROCARE protocol along with personalized add-on modules or an active control condition (ACC) based on emotional psychoeducation, and their respective booster session for each experimental condition. 80 subjects (47.5% girls) aged between 12 and 18 years (M = 14.62; SD 1.43) who completed these treatment conditions were available for the 12-month follow-up. The results demonstrate the superior long-term efficacy of the PROCARE+ intervention in mitigating emotional symptoms and obsessive-compulsive symptomatology compared to the PROCARE and ACC conditions, with effect sizes notably exceeding those commonly observed in preventive programs. While the three treatments demonstrated beneficial impacts, the pronounced results associated with PROCARE+ at the 12-month follow-up emphasized the importance of personalized treatment modules and the sustained benefits of booster sessions in the realm of preventive psychological interventions. The findings also highlight the potential role of add-on modules in enhancing the effects of the PROCARE+ condition.

The Impact of MRSA Colonization on Healthcare-Associated Infections in Long-Term Care Facility Residents: A Whole-Genome Sequencing-Based Study.

Methicillin-resistant Staphylococcus aureus (MRSA) colonization has been considered a risk factor for the development of infection, however, there are no studies that have compared the colonizing and infecting strains using whole-genome sequencing (WGS). The aim of this study is to determine the prevalence of and risk factors for MRSA colonization among long-term care facilities (LTCF) residents of Tenerife (Spain), and to analyze the epidemiological relationship between the colonizing and infecting strains using WGS. A point-prevalence study was carried out at 14 LTCFs in Tenerife from October 2020 to May 2021. Nasal swabs were cultured for MRSA. Colonized residents were followed up for two years. A phylogenetic comparison between colonization and infection strains was performed using WGS. A total of 764 residents were included. The prevalence of colonization by MRSA was 28.1% (n = 215), of which 12 (5.6%) subsequently developed infection. A close genetic relationship between colonization and infection isolates was found in three of the four (75%) residents studied. Our study confirms that colonized residents can develop serious MRSA infections from the same nasal colonization strain. Given the high prevalence of MRSA colonization in these centers, it is necessary to implement strategies with preventive measures to avoid the development of infection and the transmission of MRSA.

Effectiveness of a cardiac rehabilitation program on biomechanical, imaging, and physiological biomarkers in elderly patients with heart failure with preserved ejection fraction (HFpEF): FUNNEL + study protocol.

BACKGROUND: Patients with heart failure with preserved ejection fraction (HFpEF) have a low functional status, which in turn is a risk factor for hospital admission and an important predictor of survival in HFpEF. HFpFE is a heterogeneous syndrome and recent studies have suggested an important role for careful, pathophysiological-based phenotyping to improve patient characterization. Cardiac rehabilitation has proven to be a useful tool in the framework of secondary prevention in patients with HFpEF. Facilitating decision-making and implementing cardiac rehabilitation programs is a challenge in public health systems for HFpEF management. The FUNNEL + study proposes to evaluate the efficacy of an exercise and education-based cardiac rehabilitation program on biomechanical, physiological, and imaging biomarkers in patients with HFpEF. METHODS: A randomised crossover clinical trial is presented among people older than 70 years with a diagnosis of HFpEF. The experimental group will receive a cardiac rehabilitation intervention for 12 weeks. Participants in the control group will receive one educational session per week for 12 weeks on HFpEF complications, functional decline, and healthy lifestyle habits. VO2peak is the primary outcome. Biomechanical, imaging and physiological biomarkers will be assessed as secondary outcomes. Outcomes will be assessed at baseline, 12 weeks, and 24 weeks. DISCUSSION: Identifying objective functional parameters indicative of HFpEF and the subsequent development of functional level stratification based on functional impairment ("biomechanical phenotypes") may help clinicians identify cardiac rehabilitation responders and non-responders and make future clinical decisions. In this way, future pharmacological and non-pharmacological interventions, such as exercise, could be improved and tailored to improve quality of life and prognosis and reducing patients' hospital readmissions, thereby reducing healthcare costs.

Identification and antibiogram of Enterobacterales from direct urine samples using matrix assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) technology and disk-plate diffusion technique.

Identification and antibiogram of uropathogenic microorganisms from direct urine samples present a great clinical impact. Here, we present a combined procedure to determine identification (IDd) of bacteria through MALDI-TOF-MS technology and antibiogram (ATBd) using disk-plate diffusion technique, of UTI-producing Enterobacterales against the most used antibiotics. Ninety-four urine samples with presence of pyuria and Gram-negative bacilli were selected. The IDd showed a high success rate (90%). ATBd procedure showed a high correlation for tested antibiotics. This simplified, low cost and reduced work time two-step procedure significantly reduces results turnaround time and benefit the clinical management of patients with UTI.
