E-consults between primary care and internal medicine: implementation, accessibility, benefits, and implications.

AIM: This work aims to evaluate whether electronic consultations (e-consults) are a clinically useful, safe tool for assessing patients between primary care and internal medicine. METHODS: This is a retrospective cohort study of all e-consults ordered by the Primary Care Department to the Internal Medicine Department between September 2019 and December 2023. The results of initial consultations, emergency department visits and subsequent admissions, and survival were assessed and complaints and claims filed were reviewed. RESULTS: A total of 11,434 e-consults were recorded (55.4% women) with a mean age of 62.1 (SD19.4) years and a wide range (15-102 years). The mean response time was 2.55 (SD 1.6) days. As a result of the e-consults, 5645 patients (49.4%) were given an in-person appointment. For the remaining 5789 (50.6%), a written response was provided. Among those given appointments, the time between the response and in-person appointment was less than five days (95% of cases). Compared to those not given appointments, in-person appointments were older (p < 0.0001), visited the emergency department more times (one month: p = 0.04; three months: p = 0.001), were admitted to the hospital more times (one month: p = 0.0001; three months: p = 0.0001), and had higher mortality at one year (12.7% vs. 9.8% p = 0.0001). In the Cox analysis, only in-person appointments (RR = 1.11; p = 0.04)) and age (RR = 1.09; p < 0.01) were independent factors of mortality. No complaints or claims of any kind were registered. CONCLUSIONS: These data suggest that e-consults are a clinically useful, safe tool for assessing patients referred from primary care to internal medicine departments.

Genitourinary symptoms and sexual function in women with primary ovarian insufficiency.

OBJECTIVE: There are limited studies on urogenital symptoms in women who experience menopause before the age of 40 years due to primary ovarian insufficiency (POI) or bilateral oophorectomy (surgical POI). This study aimed to compare the urogenital symptoms, including sexuality, of women with POI to those without the condition. METHODS: This cross-sectional study conducted was in seven Latin American countries, in which postmenopausal women (with POI and non-POI) were surveyed with a general questionnaire, the Menopause Rating Scale (MRS) and the six-item Female Sexual Function Index (FSFI-6). The association of premature menopause with more urogenital symptoms and lower sexual function was evaluated with logistic regression analysis. RESULTS: Women with POI experience more urogenital symptoms (MRS urogenital score: 3.54 ± 3.16 vs. 3.15 ± 2.89, p < 0.05) and have lower sexual function (total FSFI-6 score: 13.71 ± 7.55 vs. 14.77 ± 7.57 p < 0.05) than women who experience menopause at a normal age range. There were no significant differences in symptoms when comparing women based on the type of POI (idiopathic or surgical). After adjusting for covariates, our logistic regression model determined that POI is associated with more urogenital symptoms (odds ratio [OR]: 1.38, 95% confidence interval [CI] 1.06-1.80) and lower sexual function (OR: 1.67, 95% CI 1.25-2.25). CONCLUSION: POI, whether idiopathic or secondary to bilateral oophorectomy, is associated with symptoms that affect vaginal and sexual health.

An in silico analysis of the interaction of marine sponge-derived bioactive compounds with type 2 diabetes mellitus targets DPP-4 and PTP1B.

Type 2 diabetes is a medical condition involving elevated blood glucose levels resulting from impaired or improper insulin utilization. As the number of type 2 diabetes cases increases each year, there is an urgent need to develop novel drugs having new targets and/or complementing existing therapeutic protocols. In this regard, marine sponge-derived compounds hold great potential due to their potent biological activity and structural diversity. In this study, a small library of 50 marine sponge-derived compounds were examined for their activity towards type 2 diabetes targets, namely dipeptidyl peptidase-4 (DPP-4) and protein tyrosine phosphatase 1B (PTP1B). The compounds were first subjected to molecular docking on protein models based on their respective co-crystal structures to assess binding free energies (BFE) and conformations. Clustering analysis yielded BFE that ranged from 24.54 kcal/mol to -9.97 kcal/mol for DPP-4, and from -4.98 kcal/mol to -8.67 kcal/mol for PTP1B. Interaction analysis on the top ten compounds with the most negative BFE towards each protein target showed similar intermolecular interactions and key interacting residues as in the previously solved co-crystal structure. These compounds were subjected to absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiling to characterize drug-likeness and combining the results from these analyses, (S)-6'-debromohamacanthin B was identified as a potential multi-target inhibitor of DPP-4 and PTP1B, having favorable protein interaction, no Lipinski violations, good gastrointestinal (GI) tract absorption, blood-brain barrier (BBB) penetration, and no predicted toxicity. Finally, the interaction of (S)-6'-debromohamacanthin B with the two proteins was validated using molecular dynamics simulations over 100 ns through RMSD, radius of gyration, PCA, and molecular mechanics Poisson-Boltzmann surface area (MMPBSA) confirming favorable interactions with the respective proteins.Communicated by Ramaswamy H. Sarma.

A 50-compound library previously reported from marine sponges was docked to putative T2DM targets, DDP-4 and PTP1B.(S)-6'-debromohamacanthin B was identified as a probable dual-targeting compound based on binding interactions and ADMET evaluation.Interaction of (S)-6'-debromohamacanthin B with DPP-4 and PTP1B was validated by MD simulations.

Caracterización metabólica de los cambios pulmonares estructurales en pacientes con hallazgos incidentales sugestivos de neumonía por COVID-19 en estudios 18F-FDG PET/CT. Perspectivas fisiopatológicas de imágenes multimodales obtenidas durante la pandemia / Metabolic characterization of structural lung changes in patients with findings suggestive of incidental COVID-19 pneumonia on 18F-FDG PET/CT: Pathophysiological insights from multimodal images obtained during the pandemic

Objetivo Evaluar la captación metabólica de diferentes signos tomográficos observados en pacientes con hallazgos estructurales incidentales sugestivos de neumonía por COVID-19 mediante PET/TC con 18F-FDG. Material y métodos Se analizaron retrospectivamente 596 estudios PET/TC realizados desde el 21 de febrero de 2020 hasta el 17 de abril de 2020. Tras excluir 37 exploraciones (trazadores PET diferentes a la 18F-FDG y estudios cerebrales), se evaluó la actividad metabólica de varios cambios estructurales integrados en la puntuación CO-RADS mediante el SUVmáx de estudios multimodales con 18F-FDG. Resultados Se incluyeron 43 pacientes r COVID-19 en la 18F-FDG PET/TC (edad media: 68±12,3 años, 22 varones). Los valores de SUVmáx fueron mayores en los pacientes con categorías CO-RADS 5-6 respecto a los de categorías CO-RADS inferiores (6,1±3,0 vs. 3,6±2,1, p=0,004). En los pacientes con CO-RADS 5-6, las opacidades en vidrio deslustrado, la bilateralidad y las consolidaciones mostraron valores de SUVmáx más elevados (valores de la p de 0,01, 0,02 y 0,01, respectivamente). La distribución parcheada y el patrón crazy paving también se asociaron a valores de SUVmáx más elevados (valores de p de 0,002 y 0,01). Tras el análisis multivariable, el SUVmáx se asoció significativamente con un diagnóstico estructural positivo de neumonía por COVID-19 (odds ratio=0,63, intervalo de confianza del 95%=0,41-0,90; p=0,02). La curva ROC del modelo de regresión destinado a confirmar o descartar el diagnóstico estructural de neumonía por COVID-19 mostró un AUC de 0,77 (error estándar=0,072; p=0,003). Conclusiones En aquellos pacientes remitidos a 18F-FDG PET/TC por indicaciones oncológicas y no oncológicas estándar (43/559; 7,7%) durante la pandemia, la obtención de imágenes multimodales es una herramienta útil durante la detección incidental de neumonía (AU)

Purpose To evaluate the metabolic uptake of different tomographic signs observed in patients with incidental structural findings suggestive of COVID-19 pneumonia through 18F-FDG PET/CT. Material and methods We retrospectively analyzed 596 PET/CT studies performed from February 21, 2020 to April 17, 2020. After excluding 37 scans (non-18F-FDG PET tracers and brain studies), we analyzed the metabolic activity of several structural changes integrated in the CO-RADS score using the SUVmax of multimodal studies with 18F-FDG. Results Forty-three patients with 18F-FDG PET/CT findings suggestive of COVID-19 pneumonia were included (mean age: 68±12.3 years, 22 male). SUVmax values were higher in patients with CO-RADS categories 5–6 than in those with lower CO-RADS categories (6.1±3.0 vs. 3.6±2.1, p=0.004). In patients with CO-RADS 5–6, ground-glass opacities, bilaterality and consolidations exhibited higher SUVmax values (p-values of 0.01, 0.02 and 0.01, respectively). Patchy distribution and crazy paving pattern were also associated with higher SUVmax (p-values of 0.002 and 0.01). After multivariate analysis, SUVmax was significantly associated with a positive structural diagnosis of COVID-19 pneumonia (odds ratio=0.63, 95% confidence interval=0.41–0.90; p=0.02). The ROC curve of the regression model intended to confirm or rule out the structural diagnosis of COVID-19 pneumonia showed an AUC of 0.77 (standard error=0.072, p=0.003). Conclusions In those patients referred for standard oncologic and non-oncologic indications (43/559; 7.7%) during pandemic, imaging with 18F-FDG PET/CT is a useful tool during incidental detection of COVID-19 pneumonia. Several CT findings characteristic of COVID-19 pneumonia, specifically those included in diagnostic CO-RADS scores (5–6), were associated with higher SUVmax values (AU)

Building back better: resilient environmental and occupational health systems for the next global crisis

@#Even after two years, the COVID-19 pandemic still disrupts public activities and services as it exposes vulnerabilities among the population and negatively impacts environmental conditions. The crisis also impeded global progress toward achieving Sustainable Development Goals (SDG). The Fourth Environmental and Occupational Health (EOH) Forum held virtually on November 25 to 26, 2021 provided a venue for learning about local and international COVID-19 responses to help prepare for the next global crisis. Through the systems thinking approach, the discussions prioritized analyses of leadership and governance, financing, human resource, technologies, information management, and service delivery. These analyses focused on community and/or workplace programs and services linked to air quality, waste management, psychosocial wellness, and COVID-19 vaccination. The forum amplified calls for climate actions and public health improvement and emphasized the significance of a collaborative, evidence-based, integrated public health response to a crisis underscoring the apparent interdependence of the SDGs.

COVID-19 in donation and transplant.

SARS-CoV-2 infection has had a major impact on donation and transplantation. Since the cessation of activity two years ago, the international medical community has rapidly generated evidence capable of sustaining and increasing this neccesary activity. This paper analyses the epidemiology and burden of COVID-19 in donation and transplantation, the pathogenesis of the infection and its relationship with graft-mediated transmission, the impact of vaccination on donation and transplantation, the evolution of donation in Spain throughout the pandemic, some lessons learned in SARS-CoV-2 infected donor recipients with positive PCR and the applicability of the main therapeutic tools recently approved for treatment among transplant recipients.

Impact of acetaminophen on the efficacy of immunotherapy in cancer patients.

BACKGROUND: Acetaminophen (APAP) use has been associated with blunted vaccine immune responses. This study aimed to assess APAP impact on immunotherapy efficacy in patients with cancer. PATIENTS AND METHODS: Exposure to APAP was assessed by plasma analysis and was correlated with clinical outcome in three independent cohorts of patients with advanced cancer who were treated with immune checkpoint blockers (ICBs). The immunomodulatory effects of APAP were evaluated on a preclinical tumor model and on human peripheral blood mononuclear cells (PBMCs) from healthy donors. RESULTS: Detectable plasma APAP levels at treatment onset were associated with a significantly worse clinical outcome in ICB-treated cancer patients, independently of other prognostic factors. APAP significantly reduced ICB efficacy in the preclinical MC38 model, as well as the production of PD-1 blockade-related interferon-γ secretion by human PBMCs. Moreover, reduction of ICB efficacy in vivo was associated with significantly increased tumor infiltration by regulatory T cells (Tregs). Administration of APAP over 24 h induced a significant expansion of peripheral Tregs in healthy individuals. In addition, interleukin-10, a crucial mediator of Treg-induced immune suppression, was significantly up-regulated upon treatment with ICB in cancer patients taking APAP. CONCLUSIONS: This study provides strong preclinical and clinical evidence of the role of APAP as a potential suppressor of antitumor immunity. Hence, APAP should be used with caution in patients treated with ICB.

Pembrolizumab in soft-tissue sarcomas with tertiary lymphoid structures: a phase 2 PEMBROSARC trial cohort.

Immune checkpoint inhibitors (ICIs) show limited clinical activity in patients with advanced soft-tissue sarcomas (STSs). Retrospective analysis suggests that intratumoral tertiary lymphoid structures (TLSs) are associated with improved outcome in these patients. PEMBROSARC is a multicohort phase 2 study of pembrolizumab combined with low-dose cyclophosphamide in patients with advanced STS (NCT02406781). The primary endpoint was the 6-month non-progression rate (NPR). Secondary endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and safety. The 6-month NPR and ORRs for cohorts in this trial enrolling all comers were previously reported; here, we report the results of a cohort enrolling patients selected based on the presence of TLSs (n = 30). The 6-month NPR was 40% (95% confidence interval (CI), 22.7-59.4), so the primary endpoint was met. The ORR was 30% (95% CI, 14.7-49.4). In comparison, the 6-month NPR and ORR were 4.9% (95% CI, 0.6-16.5) and 2.4% (95% CI, 0.1-12.9), respectively, in the all-comer cohorts. The most frequent toxicities were grade 1 or 2 fatigue, nausea, dysthyroidism, diarrhea and anemia. Exploratory analyses revealed that the abundance of intratumoral plasma cells (PCs) was significantly associated with improved outcome. These results suggest that TLS presence in advanced STS is a potential predictive biomarker to improve patients' selection for pembrolizumab treatment.

Endoscopic nipple-sparing mastectomy for early breast cancer: A case series of a minimally-invasive technique

@#This study aimed to share the authors’ preliminary experience with endoscopic nipple-sparing mastectomy in the Philippines. All medical records of patients who underwent endoscopic mastectomy done by the same surgeons in two institutions from March to October 2019 were collected and analyzed. Surgical margin, operating time, blood loss volume, and post-operative complications were noted. Three cases were recorded during the study period. The mean operative time was 341 minutes and the mean blood loss volume was < 20 mL. All cases had negative margins of resection on final histopathology. One patient developed ecchymosis on the axilla, while the other patients had unremarkable post-operative courses. Endoscopic nipplesparing mastectomy is a potentially safe and feasible alternative in breast cancer management. Further evaluation of the procedure is recommended.

Predictive Chromatography of Leaf Extracts Through Encoded Environmental Forcing on Phytochemical Synthesis.

Environment fluctuations can influence a plant's phytochemical profile via phenotypic plasticity. This adaptive response ensures a plant's survival under fluctuating growth conditions. However, the resulting plant extract composition becomes unpredictable, which is a problem for highly standardized medicinal applications. Here we demonstrate, for the first time, the feasibility of tracking the changes in the phytochemical profile based on real-time measurements of a few environment and extract-preparation variables. As a result, we predicted the chromatograms of Blumea balsamifera extracts through an imputation-augmented convolutional neural network, which uses the image-transformed temporal measurements of the variables. We developed a sensor network that collected data in a greenhouse and a training algorithm that concurrently generated a data representation of the implicit plant-environment interactions leading to the mutable chromatograms of leaf extracts. We anticipate the generic applicability of the method for any plant and recognize its potential for addressing the standardization problems in plant therapeutics.

Pediatric chest x-ray in covid-19 infection.

BACKGROUND: The outbreak of COVID-19 has become pandemic. Pediatric population has been less studied than adult population and prompt diagnosis is challenging due to asymptomatic or mild episodes. Radiology is an important complement to clinical and epidemiological features. OBJECTIVE: To establish the most common CXR patterns in children with COVID-19, evaluate interobserver correlation and to discuss the role of imaging techniques in the management of children. MATERIALS AND METHODS: Forty-four patients between 0 and 16 years of age with confirmed SARS-Cov-2 infection and CXR were selected. Two paediatric radiologists independently evaluated the images and assessed the type of abnormality, distribution and evolution when available. RESULTS: Median age was 79.8 months (ranging from 2 weeks to 16 years of age). Fever was the most common symptom (43.5 %). 90 % of CXR showed abnormalities. Peribronchial cuffing was the most common finding (86.3 %) followed by GGOs (50 %). In both cases central distribution was more common than peripheral. Consolidations accounted for 18.1 %. Normal CXR, pleural effusion, and altered cardiomediastinal contour were the least common. CONCLUSION: The vast majority of CXR showed abnormalities in children with COVID-19. However, findings are nonspecific. Interobserver correlation was good in describing consolidations, normal x-rays and GGOs. Imaging techniques have a role in the management of children with known or suspected COVID-19, especially in those with moderate or severe symptoms or with underlying risk factors.

Should IgM/IgG rapid test kit be used in the diagnosis of COVID-19?

Key Findings@# Current evidence does NOT support use of IgM/IgG rapid test kits for the definitive diagnosis of COVID-19 in currently symptomatic patients. • The present standard for diagnosis of COVID-19 is through qualitative detection of COVID-19 virus nucleic acid via reverse transcription polymerase chain reaction (RT-PCR). • Due to long turnaround times and complicated logistical operations, a rapid and simple field test alternative is needed to diagnose and screen patients. • An alternative to the direct detection and measurement of viral load (RT-PCR) is the qualitative detection of specific antibodies to COVID-19. ELISA (discussed in a separate rapid review) and lateral flow immunoassay (LFIA) IgM/IgG rapid test kits are two currently available, qualitative, antibody tests for COVID-19. • Two low quality clinical trials showed that there is insufficient evidence to support the use of IgM/IgG rapid test kits for the definitive diagnosis of COVID-19. Diagnostic accuracy varies greatly depending on the timing of the test. The test performed very poorly during the early phase of the disease (i.e., less than eight days from onset of symptoms). • Existing guidelines do not recommend serologic antibody tests for the diagnosis of COVID-19 in currently symptomatic patients.

Safety of aerosol therapy in children during noninvasive ventilation with helmet and total face mask / Seguridad de la aerosolterapia durante la ventilación mecánica no invasiva con helmet y mascarilla facial total en población pediátrica

Purpose: To evaluate the consequences of using nebulized drugs in patients subjected to noninvasive ventilation (NIV) with total face mask (TFM) and helmet. Design: A descriptive analytical study of a prospective patient cohort was carried out. Ambit: Pediatric intensive care unit (PICU) of a tertiary hospital. Patients: Consecutive sampling was used to include all patients admitted to the PICU and requiring NIV with helmet or TFM over a period of 29 months. No patients were excluded. Interventions: Nebulized treatment was added according to medical criteria. Variables of interest: Independent variables were age, sex, diagnosis, disease severity, ventilation parameters and nebulized drugs (if administered). Secondary outcomes were duration and failure of NIV, and length of PICU stay. Results: The most frequent diagnoses were bronchiolitis (60.5%) and asthma (23%). Patients received NIV for a median of 43h. Nebulized drugs were administered in 40% of the cases during NIV, and no adverse effects were registered. Using Bayesian statistics, the calculated probability of suffering an adverse effect was 1.3% with helmet and 0.5% with TFM (high density 95% probability intervals). Patients with helmet and nebulized therapy were in more serious condition than those who did not receive nebulization; nevertheless, no differences were observed regarding the need to change to bilevel modality. With TFM, PICU stay was shorter for the same degree of severity (p=0.033), and the NIV failure rate was higher in patients who did not receive inhaled drugs (p=0.024). Conclusions: The probability of suffering an adverse effect related to nebulization is extremely low when using a helmet or TFM. Inhaled therapy with TFM may shorten PICU stay in some patients

Objetivo: Evaluar las consecuencias de la medicación nebulizada en pacientes con ventilación no invasiva (VNI) con mascarilla facial total (MFT) y casco. Diseño: Estudio analítico descriptivo sobre una cohorte prospectiva de pacientes. Ámbito: UCIP de hospital de tercer nivel. Pacientes: Todos los pacientes ingresados en UCIP (muestreo consecutivo) con VNI con casco o MFT durante 29 meses. No se excluyeron pacientes. Intervenciones: Se añadió tratamiento nebulizado según criterio médico. Variables de interés: Independientes: edad, sexo, diagnóstico, gravedad, parámetros ventilatorios y medicación nebulizada (si se utilizaba). Secundarias: duración, fallo de VNI y estancia en UCIP. Resultados: Los diagnósticos más frecuentes fueron bronquiolitis (60,5%) y asma (23%). La mediana de conexión a VNI fue de 43 horas. Se administraron nebulizaciones durante la VNI en un 40% sin registrarse efectos adversos. La probabilidad calculada de tener un efecto adverso fue 1,3% con casco y 0,5% con MFT (estadística bayesiana, intervalo de probabilidad 95%). Los pacientes con casco y aerosolterapia tenían mayor gravedad que los que no recibieron nebulizaciones, sin encontrarse diferencias en la necesidad de cambiar a modalidad con doble nivel de presión. En los pacientes con MFT la estancia en UCIP fue menor (p=0,033) a pesar de no existir diferencias en el nivel de gravedad; la tasa de fallo de VNI fue mayor en los que no recibieron nebulizaciones (p=0,024). Conclusiones: La probabilidad de tener un efecto adverso relacionado con la nebulización es baja utilizando casco o MFT. La terapia inhalada con MFT puede disminuir la estancia en UCIP en algunos pacientes

Analyses of seven new whole genome sequences of cassava brown streak viruses in Mozambique reveals two distinct clades: evidence for new species.

Cassava brown streak disease (CBSD) caused by Cassava brown streak virus (CBSV) and Uganda cassava brown streak virus (UCBSV) is a major constraint to cassava production in Mozambique. Full genome sequences of CBSD-associated virus isolates contribute to the understanding of genetic diversity and the development of new diagnostic primers that can be used for early detection of the viruses for sustainable disease management. This study determined seven new whole CBSV genomes from total RNA isolated from cassava leaves with CBSD symptoms collected from Nampula and Zambezia in Mozambique. Phylogenetic analyses of the new genomes with published CBSV and UCBSV sequences in GenBank grouped the CBSV isolates from Mozambique into two distinct clades together with CBSV isolates from Tanzania. Clade 1 and 2 isolates shared low nucleotide (79.1-80.4%) and amino acid (86.5-88.2%) sequence identity. Further, comparisons within the seven new CBSV isolates, and between them and the single published complete CBSV sequence (CBSV_MO_83_FN434436) from Mozambique, revealed nucleotide sequence identities of 79.3-100% and 79.3-98%, respectively, and amino acid identities of 86.7-100% and 86.7-98.8%. In addition, using RDP4, a recombination analysis comprising all CBSV and UCBSV genome sequences from GenBank detect 11 recombination events. Using several comprehensive evolutionary models and statistical programs, it was confirmed that CBSV and UCBSV are distinct virus species, with an additional probable new species (clade 2).

Prácticas de analgosedación y delirium en Unidades de Cuidados Intensivos españolas: Encuesta 2013-2014 / Management of analgesia, sedation and delirium in Spanish Intensive Care Units: A national two-part survey

Objetivo: Conocer la práctica clínica real de las UCI españolas en relación con la analgosedación y delirium, y valorar cómo se ajusta a las recomendaciones actuales. Diseño: Estudio transversal descriptivo elaborado mediante encuesta nacional sobre prácticas de analgosedación y delirium de los pacientes ingresados en UCI los días 16 de noviembre de 2013 y 16 de octubre de 2014. Se envió un cuestionario a través de Internet con el aval de la SEMICYUC. Ámbito: UCI tanto públicas como privadas de todo el territorio nacional. Resultados: Se incluyeron un total de 166 UCI y a 1.567 pacientes. El 61,4% de las UCI contaban con un protocolo de sedación. El 75% de las UCI monitorizaban la sedación y agitación, con RASS como la escala empleada con mayor frecuencia. El dolor se monitorizaba en algo más de la mitad de las UCI, pero las escalas conductuales eran de muy baja implantación. El delirium también presentaba un bajo nivel diagnóstico. Entre los pacientes en ventilación mecánica el midazolam continuaba siendo un sedante de muy amplio uso. Conclusiones: Esta encuesta es la primera realizada en España sobre analgosedación y delirium y nos muestra una fotografía sobre estas prácticas, señala algunos aspectos como los relacionados con la monitorización y usos de escalas, junto con el manejo del delirium, en los que los resultados del estudio animan a desarrollar proyectos docentes que acerquen la práctica clínica real a las recomendaciones nacionales e internacionales

Objective: To know the real clinical practice of Spanish ICUs in relation to analgesia, sedation and delirium, with a view to assessing adherence to current recommendations. Design: A descriptive cross-sectional study was carried out based on a national survey on analgesia, sedation and delirium practices in patients admitted to intensive care on 16 November, 2013 and 16 October, 2014. An on-line questionnaire was sent with the endorsement of the SEMICYUC. Setting: Spanish ICUs in public and private hospitals. Results: A total of 166 ICUs participated, with the inclusion of 1567 patients. The results showed that 61.4% of the ICUs had a sedation protocol, and 75% regularly monitored sedation and agitation - the RASS being the most frequently used scale. Pain was monitored in about half of the ICUs, but the behavioral scales were very little used. Delirium monitoring was implemented in few ICUs. Among the patients on mechanical ventilation, midazolam remained a very commonly used agent. Conclusions: This survey is the first conducted in Spain on the practices of analgesia, sedation and delirium. We identified specific targets for quality improvement, particularly concerning the management of sedation and the assessment of delirium

Investigation of reverse ionic diffusion in forward-osmosis-aided dewatering of microalgae: A molecular dynamics study.

This study aimed to investigate the transport mechanisms of ions during forward-osmosis-driven (FO-driven) dewatering of microalgae using molecular dynamics (MD) simulations. The dynamical and structural properties of ions in FO systems of varying NaCl or MgCl2 draw solution (DS) concentrations were calculated and correlated. Results indicate that FO systems with higher DS concentration caused ions to have lower hydration numbers and higher coordination numbers leading to lower diffusion coefficients. The higher hydration number of Mg2+ ions resulted in significantly lower ionic permeability as compared to Na+ ions at all concentrations (p = 0.002). The simulations also revealed that higher DS concentrations led to higher accumulation of ions in the membrane. This study provides insights on the proper selection of DS for FO systems.
