RESUMO

Introducción: Streptococcus pneumoniae causa enfermedades graves en la población susceptible. La vacuna neumocócica conjugada (PCV) 13-valente (PCV13) se incluyó en el calendario infantil en 2011. Este estudio analiza la evolución de los serotipos de neumococo y de sus resistencias tras la PCV13. Métodos: Se incluyeron los neumococos serotipados en Galicia en 2011-2021. Se estudió la sensibilidad antibiótica siguiendo criterios EUCAST. Se analizaron los datos en 3 subperíodos: inicial (2011-2013), medio (2014-2017) y final (2018-2021). Se calcularon las prevalencias de los serotipos y el porcentaje de resistencia a los antibióticos más representativos. Resultados: Se incluyeron 2.869 aislados. Inicialmente el 42,7% presentaba tipos capsulares incluidos en la PCV13, frente al 15,4% al final. Los incluidos en la PCV20 y no en la PCV13 y PCV15 fueron el 12,5% inicialmente y el 41,3% al final. El 26,4% de los serotipos a lo largo del estudio no estaban incluidos en ninguna vacuna. La prevalencia del serotipo 8 se multiplicó casi por 8 y la del 12F se triplicó. El serotipo 19A fue el más resistente inicialmente. La resistencia de los serotipos 11A y 15A aumentó a lo largo del estudio. Conclusiones: La introducción de la PCV13 en la población infantil determinó un cambio en los serotipos de neumococo hacia los incluidos en la PCV20 y los no incluidos en ninguna vacuna. El serotipo 19A inicialmente fue el más resistente, y el 15A, no incluido en ninguna vacuna, merece un especial seguimiento. El serotipo 8, que fue el que más se incrementó, no mostró resistencia destacable.(AU)


Introduction: Streptococcus pneumoniae causes serious diseases in the susceptible population. The 13-valent pneumococci conjugate vaccine (PCV13) was included in the children's calendar in 2011. The objective of the study was to analyze the evolution of pneumococcal serotypes and their resistance after PCV13. Methods: This study included the pneumococci serotyped in Galicia in 2011-2021. Antibiotic susceptibility was analyzed following EUCAST criteria. The data was analyzed in 3 sub-periods: initial (2011-2013), middle (2014-2017) and final (2018-2021). The prevalence of serotypes and their percentage of resistance to the most representative antibiotics were calculated. Results: A total of 2.869 isolates were included. Initially, 42.7% isolates presented capsular types included in PCV13, compared to 15.4% at the end. Those included in PCV20 and not in PCV13 and PCV15 were 12.5% at baseline and 41.3% at the end; 26.4% of the isolates throughout the study had serotypes not included in any vaccine. The prevalence of serotype 8 multiplied almost by 8 and that of 12F tripled. The 19A serotype was initially the most resistant, while the resistance of serotypes 11A and 15A increased throughout the study. Conclusions: The introduction of PCV13 in the pediatric population determined a change in pneumococcal serotypes towards those included in PCV20 and those not included in any vaccine. Serotype 19A was initially the most resistant and the 15A, not included in any vaccine, deserves special follow-up. Serotype 8, which increased the most, did not show remarkable resistance.(AU)

RESUMO

Infection of a native joint, commonly referred to as septic arthritis, is a medical emergency because of the risk of joint destruction and subsequent sequelae. Its diagnosis requires a high level of suspicion. These guidelines for the diagnosis and treatment of septic arthritis in children and adults are intended for use by any physician caring for patients with suspected or confirmed septic arthritis. They have been developed by a multidisciplinary panel with representatives from the Bone and Joint Infections Study Group (GEIO) belonging to the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), the Spanish Society of Paediatric Infections (SEIP) and the Spanish Society of Orthopaedic Surgery and Traumatology (SECOT), and two rheumatologists. The recommendations are based on evidence derived from a systematic literature review and, failing that, on the opinion of the experts who prepared these guidelines. A detailed description of the background, methods, summary of evidence, the rationale supporting each recommendation, and gaps in knowledge can be found online in the complete document.(AU)

RESUMO

The objective of this study was to identify bacteria from the rhizosphere of the black saxaul (Haloxylon ammodendron) and test the possibility of using the bacteria for enhancement of drought and/or salt tolerance in the model plant, Arabidopsis thaliana. We collected rhizosphere and bulk soil samples from a natural habitat of H. ammodendron in Iran and identified 58 morphotypes of bacteria that were enriched in the rhizosphere. From this collection, we focused our further experiments on eight isolates. Microbiological analyses showed that these isolates have different levels of tolerance to heat, salt, and drought stresses, and showed different capabilities of auxin production and phosphorous solubilization. We first tested the effects of these bacteria on the salt tolerance of Arabidopsis on agar plate assays. The bacteria substantially influenced the root system architecture, but they were not effective in increasing salt tolerance significantly. Pot assays were then conducted to evaluate the effects of the bacteria on salt or drought tolerance of Arabidopsis on peat moss. Results showed that three of these bacteria (Pseudomonas spp. and Peribacillus sp.) effectively enhanced drought tolerance in Arabidopsis, so that while none of the mock-inoculated plants survived after 19 days of water withholding, the survival rate was 50–100% for the plants that were inoculated with these bacteria. The positive effects of the rhizobacteria on a phylogenetically-distant plant species imply that the desert rhizobacteria may be used to enhance abiotic stress in crops.(AU)

RESUMO

As a consequence of alcoholic fermentation (AF) in wine, several compounds are released by yeasts, and some of them are linked to the general quality and mouthfeel perceptions in wine. However, others, such as succinic acid, act as inhibitors, mainly of malolactic fermentation. Succinic acid is produced by non-Saccharomyces and Saccharomyces yeasts during the initial stages of AF, and the presence of some amino acids such as γ-aminobutyric acid (GABA) and glutamic acid can increase the concentration of succinic acid. However, the influence of these amino acids on succinic acid production has been studied very little to date. In this work, we studied the production of succinic acid by different strains of non-Saccharomyces and Saccharomyces yeasts during AF in synthetic must, and the influence of the addition of GABA or glutamic acid or a combination of both. The results showed that succinic acid can be produced by non-Saccharomyces yeasts with values in the range of 0.2–0.4 g/L. Moreover, the addition of GABA or glutamic acid can increase the concentration of succinic acid produced by some strains to almost 100 mg/L more than the control, while other strains produce less. Consequently, higher succinic acid production by non-Saccharomyces yeast in coinoculated fermentations with S. cerevisiae strains could represent a risk of inhibiting Oenococcus oeni and therefore the MLF.(AU)

RESUMO

The objective of this study was to investigate for the first time the role of S. cerevisiae natural barriers and endogenous cytoplasmatic bodies on the stabilization of fisetin encapsulated via sonoprocessing coupled to freeze-drying (FD) or spray drying (SD). Both protocols of encapsulation improved the resistance of fisetin against thermal treatments (between 60 and 150 °C) and photochemical-induced deterioration (light exposition for 60 days) compared to non-encapsulated fisetin (antioxidant activity retention of approximately 55% and 90%, respectively). When stored under constant relative humidity (from 32.8 to 90%) for 60 days, yeast carriers improved the half-life time of fisetin by up to 4-fold. Spray dried particles were smaller (4.9 μm) and showed higher fisetin release after simulated gastrointestinal digestion (55.7%) when compared to FD. Freeze-dried particles, in turn, tended to agglomerate more than SD (zeta potential −19.7 mV), resulting in reduced loading features (6.3 mg/g) and less efficient protection of fisetin to heat, photo, and moisture-induced deterioration. Overall, spray-dried sonoprocessed fisetin capsules are an efficient way to preserve fisetin against harsh conditions. Altogether, this report shows that sonoprocessing coupled to drying is an efficient, creative, and straightforward route to protect and deliver lipophilic fisetin using yeast capsules for food applications.(AU)

RESUMO

The aim of this study was to evaluate the impact of metal-tolerant plant growth-promoting bacteria (PGPB) isolated from the chloragogenous tissue of Aporrectodea molleri, which represents a unique habitat. Our objectives were to investigate their effects on the growth of Spinacia oleracea under heavy metal stress and assess their potential for enhancing phytoremediation capabilities. The experiment was conducted in an alkaline soil contaminated with 7 mg kg-1 of cadmium, 100 mg kg-1 of nickel, 150 mg kg-1 of copper, 300 mg kg-1 of Zinc, and mg kg-1 of 600 Manganese. The results showed that heavy metal stress considerably diminished root (42.8%) and shoot length (60.1%), biomass (80%), chlorophyll content (41%), soil alkaline (45%), and acid (51%) phosphatases (42%) and urease (42%). However, soil inoculation with bacterial isolates remarkably improved plant growth. Soil bioaugmentation increased spinach growth (up to 74.5% for root length, up to 106.3% for shoot length, and up to 5.5 folds for fresh biomass) while significantly increasing soil enzyme activity and NPK content. Multivariate data analysis indicated that soil inoculation with Bacillus circulans TC7 promoted plant growth while limiting metal bioaccumulation, whereas Pseudomonas sp. TC33 and Bacillus subtilis TC34 increased metal bioaccumulation in spinach tissues while minimizing their toxicity. Our study confirms that earthworms are a reservoir of multi-beneficial bacteria that can effectively improve phytoremediation efficiency and mitigate the toxic effects of heavy metals on plant growth. Further studies are needed to investigate the long-term effects and feasibility of using these isolates as a consortium in field applications.(AU)

RESUMO

How did Louis Pasteur, born in a small town in the Jura-Dole, still little known to the world today, become a man of global recognition and fame? The answer to this question is guided by two pivotal considerations. First is Pasteur's relationship to the representation of reality. This relationship was seeded and steadily developed since his juvenile years through practicing different forms of artistic expression, the most famous of which were subtle pastels portraying Pasteur's parents and neighbors. This genuine attraction towards art gradually became «scientificized¼ at the same time, when new means of reproducing the reality were invented, such as photography. The second consideration, critical to understand the phenomenon of Pasteur's celebrity, is a strong linkage of his research with nature-based agricultural production. Here again, deeply rooted in his youth and home environment, permeated with the taste of wine and the smell of tanned leather, Pasteur's interests necessitated the processes of communication, not only at the scientific level, but also on a daily life basis, with numerous «social actors¼ at play (ferments, silkworms etc.). Throughout his work, Pasteur had to provide himself with the means to set up these interdisciplinarity and communication. The final result was the Pasteur Institute, or rather the Pasteur Institutes and the global Pasteur network.

RESUMO

Introducción: Los programas de optimización de antimicrobianos (PROA) son herramientas clave en la adecuación de estos fármacos. La información disponible sobre la aplicación e indicadores para monitorizar estos programas en urgencias es limitada. El objetivo del estudio es conocer el grado de implantación de programas PROA en los servicios de urgencias, así como el uso de antimicrobianos en estas unidades. Material y métodos. Estudio multicéntrico retrospectivo. Se envió una invitación a todos los participantes del grupo de trabajo de farmacéuticos de urgencias REDFASTER-SEFH. Se utilizó un cuestionario de 21 ítems, contestado por un equipo formado por especialistas en los servicios de farmacia hospitalaria, urgencias, enfermedades infecciosas y microbiología. Resultados. 18 hospitales completaron la encuesta. Catorce (77,8%) disponían de un responsable PROA en la unidad. El valor de DDD por 1000 ingresos osciló entre 36,5 y 400,5 (mediana 100,4 [RIQ:57,2-157,3]). El grupo de carbapenémicos y macrólidos presentó una amplia variabilidad. Únicamente seis (33,3%) hospitales disponían de informe anual de resistencias específico para urocultivos y hemocultivos en urgencias. El porcentaje de multirresistentes en urocultivos fue del 12,5% y en hemocultivos del 12,2%. El porcentaje de adecuación en bacteremia de acuerdo con el resultado del hemocultivo fue del 81,0% (RIQ:74,6-85,0%), y en infección urinaria del 78,0% (RIQ:71,5-88,0%). Conclusiones. Pese a la existencia de responsables PROA, actividades formativas y guías de tratamiento en urgencias, la información sobre el uso de antimicrobianos y el perfil de resistencias en estas unidades es limitado. Futuras actividades han de ir encaminadas a mejorar la información sobre los resultados PROA propios para estas unidades. (AU)


Introduction: 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 theextent of ASP implementation in the emergency departments, as well as the use of antimicrobials in these units. Material and 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. (AU)

RESUMO

Objectives. Our observational, retrospective study aimed to determine the correlation between bacteria isolated from bronchial aspirates of pediatric ICU patients (PICU) with respiratory infections and those obtained from conjunctival swabs of the same patients exhibiting clinical conjunctivitis. Material and methods. Throughout the period from 2015 to 2022, we reviewed all clinically significant bronchial aspirates (≥105 CFU/mL) and positive conjunctival swabs obtained from PICU patients. These records were retrieved from the microbiology database, cross-referencing the data to identify patients who tested positive for both during the same clinical episode. Results. The median age of the patients was 5 months (interquartile range: 1-7). Among the cohort, twenty-one patients exhibited positivity in both bronchial aspirate and conjunctival swab samples, showcasing a microbial match in 85.71% of cases (18 out of 21). The most frequently isolated microorganisms were Haemophilus influenzae (55.6%), followed by Pseudomonas aeruginosa (14.3%), Klebsiella aerogenes (9.5%), and Escherichia coli, Stenotrophomonas maltophilia, and Enterobacter cloacae, each accounting for 4.8% of the isolates. Conclusions. Our study demonstrates a strong concordance between the isolated microorganisms from both samples in patients presenting clear symptoms of clinical conjunctivitis. These findings provide a basis for future prospective studies that may leverage conjunctival swabs as a predictive tool for identifying microorganisms involved in respiratory infections. (AU)


Objetivos. Nuestro estudio observacional y retrospectivo tuvo como objetivo determinar la correlación entre las bacterias aisladas de aspirados bronquiales de pacientes de UCI pediátrica (UCIP) con infecciones respiratorias y las obtenidas de hisopos conjuntivales de los mismos pacientes que presentaban conjuntivitis clínica. Material y métodos. A lo largo del periodo comprendido entre 2015 y 2022, se revisaron todos los aspirados bronquiales clínicamente significativos (≥105 UFC/mL) y los hisopos conjuntivalespositivos obtenidos de pacientes de UCIP. Estos registros se recuperaron de la base de datos de microbiología, cruzando los datos para identificar a los pacientes que dieron positivo en ambos durante el mismo episodio clínico. Resultados. La mediana de edad de los pacientes fue de 5 meses (rango intercuartílico: 1-7). Entre la cohorte, veintiún pacientes presentaron positividad tanto en las muestras de aspirado bronquial como en las de hisopo conjuntival, mostrando una coincidencia microbiana en el 85,71% de los casos (18 de 21). Los microorganismos más frecuentemente aislados fueron Haemophilus influenzae (55,6%), seguido de Pseudomonas aeruginosa (14,3%), Klebsiella aerogenes (9,5%) y Escherichia coli, Stenotrophomonas maltophiliay Enterobacter cloacae, cada uno de los cuales representó el 4,8% de los aislamientos. Conclusiones. Nuestro estudio demuestra una fuerte concordancia entre los microorganismos aislados de ambas muestras en pacientes que presentan síntomas claros de conjuntivitis clínica. Estos hallazgos proporcionan una base para futuros estudios prospectivos que podrían aprovechar los hisopos conjuntivales como herramienta predictiva para identificar microorganismos implicados en infecciones respiratorias.

RESUMO

The practice of designating two or more authors as equal contributors (ECs) on a scientific publication is increasingly common as a form of sharing credit. However, EC authors are often unclearly attributed on curriculum vitae (CVs) or citation engines, and it is unclear how research teams determine author order within an EC listing. In response to studies showing that male authors were more likely to be placed first in an EC listing, the American Society for Microbiology (ASM) required that authors explain the reasons for author order beginning in 2020. In this study, we analyze data from over 2,500 ASM publications to see how this policy affected gender bias and how research teams are making decisions on author order. Data on publications from 2018 to 2021 show that gender bias was largely nonsignificant both before and after authors were asked by ASM to provide an EC statement. The most likely reasons for EC order included alphabetical order, seniority, and chance, although there were differences for publications from different geographic regions. However, many research teams used unique methods in order selection, highlighting the importance of EC statements to provide clarity for readers, funding agencies, and tenure committees. IMPORTANCE: First-author publications are important for early career scientists to secure funding and educational opportunities. However, an analysis published in eLife in 2019 noted that female authors are more likely to be placed second even when both authors report they have contributed equally. American Society for Microbiology announced in response that they would require submissions to include a written justification of author order. In this paper, we analyze the resultant data and show that laboratories are most likely to use some combination of alphabetical order, seniority, and chance to determine author order. However, the prevalence of these methods varies based on the research team's geographic location. These findings highlight the importance of equal contributor statements to provide clarity for readers, funding agencies, and tenure committees. Furthermore, this work is critically important for understanding how these decisions are made and provides a glimpse of the sociology of science.

RESUMO

Introduction: Tuberculous meningitis (TBM), the most serious form of tuberculosis, results in high mortality and long-term disability in low-resource countries. We investigated temporal trends in mortality and sequelae in a high-resource low-incidence country. Methods: We performed a retrospective cohort study of all adult patients with TBM at two third-level teaching hospitals in Barcelona (Spain), between January 1990 and December 2017, assessing temporal trends in mortality and sequelae after 12 months over four consecutive 7-year time windows. Rates observed across the four periods were adjusted for covariates. Results: Of the 135 cases included, all but one started tuberculosis (TB) treatment and 120 (89.6%) received rifampicin, isoniazid, and pyrazinamide, with or without ethambutol. The probability of being alive at month 12 was 81.8%, with no differences among the four periods: in comparison with the 1990–1996 period, the adjusted hazard ratios and 95% confidence intervals (CI) were 2.55 (0.71–9.25), 0.70 (0.13–3.85), and 1.29 (0.28–5.91) for the 1997–2003, 2004–2010, and 2011–2017 periods respectively. Sequelae were present in 28.3% at month 12, with no differences across the four periods in the adjusted analysis: in comparison with the 1990–1996 period, the odds ratios and 95% CIs were 0.80 (0.09–7.22); 1.94 (0.21–17.96), and 2.42 (0.25–23.07) for the 1997–2003, 2004–2010, and 2011–2017 periods respectively. Conclusion: This study shows that TBM still causes high mortality and disability even in a high-resource low-incidence TB setting and without improvement over time.(AU)


Introducción: La meningitis tuberculosa (TBM), la forma más grave de tuberculosis, provoca una alta mortalidad y discapacidad a largo plazo en países con bajos recursos. Nuestro objetivo es investigar la tendencia temporal de la mortalidad y las secuelas en un país con recursos elevados y baja incidencia. Métodos: Hemos realizado un estudio de cohortes retrospectivo de los pacientes adultos con TBM en dos hospitales universitarios de tercer nivel en Barcelona (España), entre 1990 y 2017, evaluando las tendencias temporales de mortalidad y secuelas a los 12 meses, comparando cuatro periodos consecutivos de siete años. Las tasas observadas en los cuatro periodos se han ajustado por covariables. Resultados: De los 135 casos incluidos, todos menos uno inició tratamiento antituberculoso y 120 (89,6%) recibieron rifampicina, isoniazida y pirazinamida, con o sin etambutol. La probabilidad de estar vivo a los 12 meses fue de 81,8%, sin diferencias entre los cuatro periodos: en comparación con el periodo 1990-1996, los coeficientes de riesgo ajustados y los intervalos de confianza (IC) del 95% fueron 2,55 (0,71-9,25), 0,70 (0,13-3,85) y 1,29 (0,28-5,91) para los periodos 1997-2003, 2004-2010 y 2011-2017, respectivamente. Las secuelas estaban presentes en 28,3% en el mes 12, sin diferencias entre los cuatro periodos en el análisis ajustado: en comparación con el periodo 1990-1996, los coeficientes de probabilidad y los IC 95% fueron 0,80 (0,09-7,22); 1,94 (0,21-17,96) y 2,42 (0,25-23,07) para los periodos 1997-2003, 2004-2010 y 2011-2017, respectivamente. Conclusión: Este estudio muestra que la TBM todavía causa una alta mortalidad y discapacidad sin mejoría con el tiempo, incluso en un entorno con baja incidencia de tuberculosis y con elevados recursos.(AU)
