[Antibiotic stewardship programs in the Spanish emergency services: PROA-URG Study]. / Programas de optimización del uso de antimicrobianos en los servicios de urgencias españoles: Estudio PROA-URG.

OBJECTIVE: Antimicrobial stewardship programs (ASP) have become a key tool in the adaptation of these drugs to the health system. The information available on the application and indicators used in these programs in emergency departments is scarce. The objective of this study is to know the extent of ASP implementation in the emergency departments, as well as the use of antimicrobials in these units. METHODS: Multicenter retrospective study. An invitation was sent to all participants of the REDFASTER-SEFH emergency pharmacist working group. A questionnaire was used consisting of 21 items, answered by a team made up of a pharmacist, emergency room specialist, infectious disease specialist and microbiologist. RESULTS: Eighteen hospitals completed the survey. Fourteen (77.8%) had an ASP manager. The DDD value per 1000 admissions ranged between 36.5 and 400.5 (median: 100.4 [IQR:57.2-157.3]). Both carbapenem and macrolide group presented wide variability in use. Six (33.3%) hospitals had an annual report on the specific resistance profile for urine and blood cultures. The percentage of multi-drug resistant strains in urine cultures was 12.5% and in blood cultures 12.2%. The percentage of adequacy in the bacteremia treatment was 81.0% (IQR:74.6-85.0%), while in urinary tract infections was 78.0% (IQR:71.5-88.0). CONCLUSIONS: Despite the existence of ASP members in emergency services, as well as the training activity and local guidelines is common. knowledge of the use of antimicrobials and resistances is limited. Future activities must be aimed at improving information about the ASP results in these units.

A prospective ecological risk assessment of high-efficiency III-V/silicon tandem solar cells.

III-V/Silicon tandem solar cells offer one of the most promising avenues for high-efficiency, high-stability photovoltaics. However, a key concern is the potential environmental release of group III-V elements, especially arsenic. To inform long-term policies on the energy transition and energy security, we develop and implement a framework that fully integrates future PV demand scenarios with dynamic stock, emission, and fate models in a probabilistic ecological risk assessment. We examine three geographical scales: local (including a floating utility-scale PV and waste treatment), regional (city-wide), and continental (Europe). Our probabilistic assessment considers a wide range of possible values for over one hundred uncertain technical, environmental, and regulatory parameters. We find that III-V/silicon PV integration in energy grids at all scales presents low-to-negligible risks to soil and freshwater organisms. Risks are further abated if recycling of III-V materials is considered at the panels' end-of-life.

Oral feeding trajectories and neurodevelopmental outcomes at 12 and 24 month follow-up for preterm infants.

BACKGROUND: Few studies characterize feeding performance in the NICU when predicting neurodevelopmental outcomes. Our objective was to investigate the relationship between time to full oral feeds (FULL-PO) and neurodevelopmental and feeding outcomes in the first 2 years in preterm infants admitted to the NICU. METHODS: This retrospective study included infants born between 01/01/2014-07/31/2017, gestational age < 32 weeks and/or birth weight < 1500 g. We examined feeding difficulties, cerebral palsy, and Bayley scores for those reaching FULL-PO at a post menstrual age (PMA)≤38.0 weeks (EARLY) vs.>38.0 weeks (LATE). Additionally, the oral feeding achieved at various timepoints between 36- and 42-weeks postmenstrual age (PMA) was measured to construct a timeline of oral feeding acquisition. RESULTS: Of 192 infants, 147(77%) achieved FULL-PO EARLY and 45(23%) LATE. Comorbidities and length of stay were higher and unadjusted Bayley scores were lower at 12 months corrected age (CA) and 24 months chronological age (CH) in the LATE group. Feeding difficulties were higher in the LATE group at 24 months CH. Infants born < 27-28 weeks GA were more likely to achieve oral feeding at a later PMA. Infants with bronchopulmonary dysplasia (BPD) had significant feeding and developmental delays. CONCLUSIONS: Establishing full oral feeds by 38.0 weeks PMA may be used as a predictor for feeding difficulties at 24 months CH. Infants born < 27-28 weeks GA and those with BPD are more likely to take extended amounts of time to achieve full oral feeding and need additional feeding support. Infants with BPD are high risk for neurodevelopmental delays.

Diagnóstico por imagen de las metástasis vertebrales / Imaging diagnosis of vertebral metastasis

La columna vertebral es la tercera ubicación más frecuente para la enfermedad metastásica, después del pulmón y el hígado. Por otra parte, los tumores óseos más recurrentes son las metástasis, siendo la columna su principal lugar de localización. En este trabajo se realiza una revisión de las diferentes técnicas de imagen disponibles, tanto radiológicas como de medicina nuclear, y de la apariencia morfológica de las metástasis de columna en cada una de ellas. La resonancia magnética (RM) es la mejor modalidad de imagen para la detección de metástasis en la columna. Es importante efectuar el diagnóstico diferencial entre fractura vertebral de causa osteoporótica y patológica. La compresión medular es una complicación grave de la enfermedad metastásica y su valoración mediante imagen a través de escalas objetivas es determinante para la estimación de la estabilidad de la columna y, por consiguiente, para establecer el tratamiento. Por último, se comentan brevemente las técnicas de intervencionismo percutáneo.(AU)

The Effectiveness of Guselkumab in Patients With Hidradenitis Suppurativa Under Clinical Practice Conditions: A Spanish Multicentre Retrospective Study / fectividad de guselkumab en pacientes con hidradenitis supurativa en condiciones de práctica clínica: estudio retrospectivo y multicéntrico en España

Background Hidradenitis suppurativa (HS) is a chronic skin condition causing lesions in which high levels of interleukin (IL)-23 and T-helper 17 cells are found. Adalimumab remains the only approved treatment. Guselkumab, an antibody targeting the p19 protein subunit of extracellular IL-23, is approved for the treatment of moderate–severe psoriasis, but evidence on its efficacy in treating HS is limited.Objectives To assess the effectiveness and safety of guselkumab in treating moderate–severe HS under clinical practice conditions. Methods A multicentre retrospective observational study was carried out in 13 Spanish Hospitals including adult HS patients treated with guselkumab within a compassionate use programme (March 2020–March 2022). Data referred to patient demographic and clinical characteristics at treatment initiation (baseline), patient-reported outcomes (Numerical Pain Rating Scale [NPRS] and Dermatology Life Quality Index [DLQI]), physician scores (International Hidradenitis Suppurativa Severity Score System [IHS4], HS Physical Global Score [HS-PGA] and Hidradenitis Suppurativa Clinical Response [HiSCR]) were recorded at baseline and at 16, 24, and 48 weeks of treatment. Results A total of 69 patients were included. Most (84.10%) had severe HS (Hurley III) and had been diagnosed for over ten years (58.80%). The patients had been subjected to multiple non-biological (mean 3.56) or biological (mean 1.78) therapies, and almost 90% of those treated with biologics had received adalimumab (AU)

Antecedentes La hidradenitis supurativa (HS) es una situación cutánea crónica que causa lesiones en las que se encuentran altos niveles de interleucina (IL)-23 y células TH-17 colaboradoras, siendo adalimumab el único tratamiento aprobado. Guselkumab, un anticuerpo que focaliza la subunidad de la proteína p19 de IL-23 extracelular, ha sido aprobado para tratar la psoriasis de moderada a severa, siendo limitada la evidencia sobre su eficacia en el tratamiento de la HS. Objetivos Evaluar la efectividad y seguridad de guselkumab para el tratamiento de la HS de moderada a severa, en condiciones de práctica clínica. Métodos Se llevó a cabo un estudio observacional retrospectivo y multicéntrico en 13 hospitales españoles, que incluyó pacientes adultos de HS tratados con guselkumab, dentro de un programa de uso compasivo (de marzo de 2020 a marzo de 2022). Se registraron al inicio y a las 16, 24 y 48 semanas de tratamiento los datos referentes a las características demográficas y clínicas de los pacientes, los resultados reportados por el paciente (Numerical Pain Rating Scale [NPRS] y Dermatology Life Quality Index [DLQI]), puntuaciones del facultativo (International Hidradenitis Suppurativa Severity Score System [IHS4], HS Physical Global Score [HS-PGA] e Hidradenitis Suppurativa Clinical Response [HiSCR]). Resultados Se incluyó un total de 69 pacientes, de los cuales la mayoría (84,10%) tenían HS severa (Hurley III) y habían sido diagnosticados hacía más de 10 años (58,80%). Dichos pacientes habían sido sometidos a múltiples terapias no biológicas (media 3,56) o biológicas (media 1,78), y casi el 90% de los tratados con biológicos habían recibido adalimumab. Se observó una reducción significativa de las puntuaciones IHS4, HS-PGA, NPRS y DLQI desde el inicio hasta las 48 semanas del tratamiento con guselkumab (total p<0,01).

Percepción y prioridades respecto al proceso de consentimiento informado quirúrgico; un análisis mediante métodos mixtos

Objetivo: Identificar las principales preocupaciones antes y después de realizarse un procedimiento quirúrgico, e identificar diferencias basadas en género, edad y nivel de escolaridad. Material y Método: Mediante un muestreo no probabilístico incidental se aplicaron 201 encuestas semiestructuradas a personas en la sala de espera del HSJD. Las respuestas fueron procesadas mediante un análisis mixto donde se organizaron categorías por unidades de significancia y se ordenaron de forma decreciente para luego comparar según edad, género y escolaridad. Resultados: Respecto a los aspectos que las personas consideran relevante conocer previo a la cirugía, 4 categorías concentran el 71 % del total: 1. Riesgos, complicaciones y secuelas, 2. Explicación del procedimiento, 3. Beneficios y pronóstico, 4. Cuidados y evaluaciones previas. En relación con lo que le gustaría que le explicaran después, se prioriza: 1. Conocer los resultados del procedimiento (19,3%), 2. Control, derivaciones y cuidados paliativos (15%), 3. Tiempo de recuperación (13,7%). Diferencias significativas: una mayor necesidad de acompañamiento y explicación de la patología expresada por hombres, el interés por conocer y los aspectos relacionados con funcionalidad postoperatoria en personas entre 18-65 años, el interés de conocer los cuidados y evaluaciones previas, conocer los resultados del procedimiento, los cuidados de la herida y la funcionalidad posoperatoria según nivel educacional. Discusión y conclusión: Existen variaciones significativas en contenido prioritario según edad, género y nivel educacional. Finalmente, el presente artículo proporciona evidencia en cuanto a las principales prioridades de pacientes en el sistema público chileno para el consentimiento informado.

Aim: To identify the main concerns before and after undergoing a surgical procedure, and to identify differences based on gender, age and level of education. Material and Method: 201 semi-structured surveys were administered to people in the waiting room of the HSJD by means of incidental non-probabilistic sampling. The responses were processed by means of a mixed analysis in which categories were organized by units of significance and ordered in decreasing order to then compare according to age, gender and schooling. Results: Regarding the aspects that people considered relevant to know before surgery, 4 categories accounted for 71% of the total: 1. Risks, complications and sequels, 2. Explanation of the procedure, 3. Benefits and prognosis, 4. Prior care and evaluations. In relation to what you would like to have explained to you afterwards, priority is given to: 1. knowing the results of the procedure (19.3%), 2. Monitoring, referrals and palliative care (15%), 3. Recovery time (13.7%). Significant differences: a greater need for accompaniment and explanation of the pathology expressed by men, interest in knowing and aspects related to postoperative functionality in persons between 18-65 years of age, interest in knowing the previous care and evaluations, knowing the results of the procedure, wound care and postoperative functionality according to educational level. Discussion and conclusion: There are significant variations in priority content according to age, gender and educational level. Finally, the present article provides evidence regarding the main priorities of patients in the chilean public system for informed consent.

Clinical and neurodevelopmental outcomes in premature infants exposed to intravenous fish- and soybean oil-based lipid emulsions.

BACKGROUND: The optimal composition of lipid emulsions in parenteral nutrition (PN) for premature infants remains controversial. This study examined the effects of a combination of soybean oil-based (SoyLE) and fish oil-based (FishLE) lipid emulsions compared to FishLE as monotherapy on the lipid and fatty acid profiles and clinical outcomes of premature infants requiring prolonged PN. METHODS: 42 premature infants received FishLE+SoyLE or FishLE. Serum concentrations of lipoproteins and 29 fatty acids (FA) were measured at baseline, 4, and 8 weeks of PN and growth and neurodevelopmental outcomes were measured at 3, 6, 12, 18, and 24 months of life. RESULTS: Lipid profiles were similar between groups. Plasma concentrations of ω-6 fatty acids tended to decrease over time in both groups. Concentrations of most ω-3 fatty acids, in particular docosapentaenoic acid, eicosapentaenoic acid, and docosahexaenoic acid, were significantly increased over time in the FishLE+SoyLE group whereas they did not change in the FishLE alone group. However, serum concentrations of almost all fatty acids were similar between groups at the end of the study period. No differences in growth parameters including weight, height, fronto-occipital circumference (FOC), and body mass index (BMI) were observed up to two years of age. Similarly, there were no differences in neurodevelopmental test scores at 6, 12, 18, and 24 months of age. CONCLUSIONS: No substantial differences in lipid profiles and short clinical outcomes were found in infants exposed to FishLE+SoyLE when compared to FishLE.

Epigenetic regulation of functional candidate genes for milk production traits in dairy sheep subjected to protein restriction in the prepubertal stage.

BACKGROUND: As the prepubertal stage is a crucial point for the proper development of the mammary gland and milk production, this study aims to evaluate how protein restriction at this stage can affect methylation marks in milk somatic cells. Here, 28 Assaf ewes were subjected to 42.3% nutritional protein restriction (14 animals, NPR) or fed standard diets (14 animals, C) during the prepubertal stage. During the second lactation, the milk somatic cells of these ewes were sampled, and the extracted DNA was subjected to whole-genome bisulfite sequencing. RESULTS: A total of 1154 differentially methylated regions (DMRs) were identified between the NPR and C groups. Indeed, the results of functional enrichment analyses of the genes harboring these DMRs suggested their relevant effects on the development of the mammary gland and lipid metabolism in sheep. The additional analysis of the correlations of the mean methylation levels within these DMRs with fat, protein, and dry extract percentages in the milk and milk somatic cell counts suggested associations between several DMRs and milk production traits. However, there were no phenotypic differences in these traits between the NPR and C groups. CONCLUSION: In light of the above, the results obtained in the current study might suggest potential candidate genes for the regulation of milk production traits in the sheep mammary gland. Further studies focusing on elucidating the genetic mechanisms affected by the identified DMRs may help to better understand the biological mechanisms modified in the mammary gland of dairy sheep as a response to nutritional challenges and their potential effects on milk production.

The patients had been subjected to multiple non-biological (mean: 3.56) or biological (mean: 1.78) therapies, and almost 90% of those treated with biologics had received adalimumab. A significant decrease in IHS4, HS-PGA, NPRS, and DLQI scores was observed from baseline to 48weeks of guselkumab treatment (all P<.01). HiSCR was achieved in 58.33% and 56.52% of the patients at 16 and 24weeks, respectively. Overall, 16 patients discontinued treatment, mostly due to inefficacy (n=7) or loss of efficacy (n=3). No serious adverse events were observed. CONCLUSIONS: Our results indicate that guselkumab may be a safe and effective therapeutic alternative for patients with severe HS that fail to respond to other biologics.

Headache features in people with whiplash associated disorders: A scoping review.

BACKGROUND: Whiplash-associated headache (WAH) is one of the most common symptoms after a whiplash injury, leading to high disability. Nevertheless, the clinical characteristics of WAH have not been well described. OBJECTIVE: To synthesise the existing literature on the clinical characteristics of WAH. DESIGN: Scoping review. METHODS: The protocol for this scoping review was registered in Open Science Framework and the PRISMA extension for Scoping Reviews tool was used to ensure methodological and reporting quality. A systematic search was conducted in PubMed, EMBASE, CINAHL, Web of Science and Scopus. The search was performed by one author and the screening of articles was conducted by two authors independently. RESULTS: A total of 11363 articles were initially identified and finally 26 studies were included in the review. Headache intensity was the most commonly reported feature. Headache duration, frequency and location were also reported in at least four studies. Few studies reported physical impairments that may be related to the presence of WAH. A differentiation with concussion characteristics was only performed in eight studies. CONCLUSION: WAH appears to be of mild to moderate intensity, typically with episodes of short duration which is commonly experienced in the occipital region amongst other regions, and with a tendency to reduce in intensity over time.

Headache production during physical examination in patients with and without headache attributed to a whiplash injury: A case-control study.

BACKGROUND: Provocation of headache on physical examination of the neck may reflect a role of cervical structures in the presence of acute whiplash-associated headache (WAH). OBJECTIVE: To determine differences in headache provocation during physical tests in people with and without WAH after a whiplash injury. DESIGN: Case-control study. METHODS: Forty-seven people with acute whiplash-associated disorders participated, 28 with WAH. Passive accessory intervertebral movement over the tubercle of C1, the spinous processes of C2-C3 and facet joints of C0-C4, the flexion-rotation test (FRT), manual palpation of cranio-cervical muscles and the upper limb neurodynamic test + cranio-cervical flexion were assessed bilaterally twice by a blinded examiner; headache provocation was determined. Cohen's kappa and Chi-squared were determined to evaluate the intra-rater reliability of test results and differences between groups, respectively. A logistic regression model was also performed. RESULTS: Intra-rater reliability of headache provocation was good or excellent for most tests. Significant differences between groups were found with higher positive tests in WAH for the assessment of C2 (68%), the most painful side of C0-C1 (57%), C1-C2 (75%) and C2-C3 (53%), most (79%) and least (25%) restricted sides of the FRT, and manual palpation of the most painful side for the trapezius (53%), masseter (50%) and temporalis (46%) muscles. Provocation of headache during the assessment of C2 and C1-C2 on the most painful side demonstrated the highest association with WAH. CONCLUSION: Mechanical provocation of headache is more frequent in people with WAH than in those without headache soon after a whiplash injury.

Physical testing in patients with acute whiplash-associated disorders: A within session test-retest reliability study.

BACKGROUND: People with whiplash-associated disorders (WAD) commonly present with a variety of physical impairments. However, the reliability of physical tests has not been established for patients with acute WAD. OBJECTIVE: To assess test-retest reliability of different physical tests in acute WAD. DESIGN: Intra-rater test-retest reliability. METHODS: Patients with acute WAD were recruited. Physical tests were used to evaluate articular, muscular and neural systems in two blocks of measurements separated by 10 min. Bland-Altman plots were performed to assess intrarater agreement, which included calculation of the mean difference (d) between rates, the 95% CI for d, the standard deviation of the differences and the 95% limits of agreement. Reliability was calculated via the standard error of measurement, the minimal detectable change, percent of agreement, the intraclass-correlation coefficient, and kappa coefficient. RESULTS: 47 patients participated. Test-retest reliability was excellent or good for almost all measures, except for extension ROM, ULTT for the radial nerve, and active cervical extension and upper cervical rotation performed in 4-point kneeling, which presented moderate reliability. Systematic bias was found in cervical ROM in flexion, left and right lateral-flexion, left and right rotation; left ULTT for radial nerve; right trapezius, suboccipitalis and temporalis muscles, left temporalis; C3, both sides of C1-C2, left C3-C4. CONCLUSION: The majority of physical tests achieved good or excellent test-retest intra-rater reliability when tested in patients with acute WAD. Findings must be considered with caution for those tests which demonstrated systematic bias. Additional research is warranted to evaluate inter-rater reliability.
