Background: Pseudomonas aeruginosa healthcare-associated infections are one of the top antimicrobial resistance threats world-wide. In order to analyze the current trends, we performed a Spanish ...nation-wide high-resolution analysis of the susceptibility profiles, the genomic epidemiology and the resistome of P. aeruginosa over a five-year time lapse. Methods: A total of 3.180 nonduplicated P. aeruginosa clinical isolates from two Spanish nation-wide surveys performed in October 2017 and 2022 were analyzed. MICs of 13 antipseudomonals were determined by ISO-EUCAST. Multidrug resistance (MDR)/extensively drug resistance (XDR)/difficult to treat resistance (DTR)/pandrug resistance (PDR) profiles were defined following established criteria. All XDR/DTR isolates were subjected to whole genome sequencing (WGS). Findings: A decrease in resistance to all tested antibiotics, including older and newer antimicrobials, was observed in 2022 vs 2017. Likewise, a major reduction of XDR (15.2% vs 5.9%) and DTR (4.2 vs 2.1%) profiles was evidenced, and even more patent among ICU isolates XDR (26.0% vs 6.0%) and DTR (8.9% vs 2.6%) (p < 0.001). The prevalence of Extended-spectrum β-lactamase/carbapenemase production was slightly lower in 2022 (2.1%. vs 3.1%, p = 0.064). However, there was a significant increase in the proportion of carbapenemase production among carbapenem-resistant strains (29.4% vs 18.1%, p = 0.0246). While ST175 was still the most frequent clone among XDR, a slight reduction in its prevalence was noted (35.9% vs 45.5%, p = 0.106) as opposed to ST235 which increased significantly (24.3% vs 12.3%, p = 0.0062). Interpretation: While the generalized decrease in P. aeruginosa resistance, linked to a major reduction in the prevalence of XDR strains, is encouraging, the negative counterpart is the increase in the proportion of XDR strains producing carbapenemases, associated to the significant advance of the concerning world-wide disseminated hypervirulent high-risk clone ST235. Continued high-resolution surveillance, integrating phenotypic and genomic data, is necessary for understanding resistance trends and analyzing the impact of national plans on antimicrobial resistance.

The objective of the study was to evaluate the effects of a multidisciplinary intervention on the outcomes of polypathological patients (PP).
A multicenter quasi-experimental pre-post study with a ...12-month follow up was performed. In-hospital, at discharge and outpatient clinics patients who met criteria of PP between March 2012 and October 2013 were included. The multidisciplinary approach was defined by 11 interventions performed by general practitioners, internal medicine physicians, team care nurses and hospital pharmacists. The primary outcome was reduction in the number of hospital admissions and days of hospitalization. Secondary outcomes included mortality and the effects of 11 interventions on mortality.
420 patients were included. Mean patient age was 77.3 (SD: 8.90) and average number of PP defining categories was 2.99 (SD: 1.00). Number of hospital admissions and days of hospitalization decreased significantly after intervention: 1.52 (SD: 1.35) versus 0.82 (SD: 1.29), p<0.001, and 13.77 (SD: 15.20) versus 7.21 (SD: 12.90), p<0.001 respectively. 12-month mortality was 37.7%. PP who failed to receive a structured medical visit from the internal medicine physician and educational workshops from the team care nurses had a higher risk of exitus in the next 12 months, HR: 1.68; 95% CI: 1.15–2.46, p=0.007 and HR: 2.86; 95% CI: 1.92–4.27, p<0.001, respectively.
This multidisciplinary intervention reduced the risk of PP hospital admission and days of hospitalization. Educational workshop programs for PP and their caregivers and structured IM medical visits were associated with improvements of survival.
El objetivo del estudio fue evaluar los resultados en salud tras la implantación de una intervención multidisciplinar a pacientes pluripatológicos (PP).
Se realizó un estudio multicéntrico antes-después cuasi-experimental, con seguimiento a 12 meses. Se incluyeron pacientes que cumplían los criterios de PP entre marzo de 2012 y octubre de 2013, tanto en el ámbito hospitalario como en atención primaria. El enfoque multidisciplinar fue definido por 11 intervenciones realizadas por médicos de familia, médicos internistas, enfermeras y farmacéuticos hospitalarios. El resultado fundamental fue la reducción en el número de ingresos hospitalarios y días de hospitalización al año de seguimiento. Los resultados secundarios incluyeron la mortalidad y los efectos de las intervenciones sobre la misma.
Se incluyeron 420 pacientes. La edad media de los pacientes fue de 77,3 (DE: 8,90) y la media de categorías definitorias de PP fue de 2,99 (DE: 1,00). El número de ingresos hospitalarios y los días de hospitalización disminuyeron significativamente después de la intervención: 1,52 (DE: 1,35) versus 0,82 (DE: 1,29), p<0,001 y 13,77 (DE: 15,20) versus 7,21 (DE: 12,90), p<0,001, respectivamente. La mortalidad a los 12 meses fue del 37,7%. Los PP que no recibieron la visita médica estructurada del médico internista tras la inclusión y los talleres educativos de las enfermeras tuvieron un mayor riesgo de exitus en los 12 meses de seguimiento, HR: 1,68; IC del 95%: 1,15-2,46, p=0,007 y HR: 2,86; IC del 95%: 1,92-4,27, p<0,001, respectivamente.
Esta intervención multidisciplinaria reduce el riesgo de ingreso y los días de ingreso hospitalario en PP. Los programas de talleres educativos para PP y sus cuidadores, y las visitas médicas estructuradas por parte de medicina interna se asociaron con una mayor supervivencia.
Public health officials are responding to an outbreak of fungal meningitis among patients who received procedures under epidural anesthesia at two clinics (River Side Surgical Center and Clinica K-3) ...in Matamoros, Mexico, during January 1-May 13, 2023. This report describes outbreak epidemiology and outlines interim diagnostic and treatment recommendations.
Interim recommendations for diagnosis and management were developed by the Mycoses Study Group Research Education and Consortium (MSGERC) based on the clinical experience of clinicians caring for patients during the current outbreak or during previous outbreaks of healthcare-associated fungal meningitis in Durango, Mexico, and the United States.
As of July 7, 2023, the situation has evolved into a multistate and multinational fungal meningitis outbreak. A total of 185 residents in 22 U.S. states and jurisdictions have been identified who might be at risk of fungal meningitis because they received epidural anesthesia at the clinics of interest in 2023. Among these patients, 11 suspected, 10 probable, and 10 confirmed U.S. cases have been diagnosed, with severe vascular complications and eight deaths occurring. Fusarium solani species complex has been identified as the causative agent, with antifungal susceptibility testing of a single isolate demonstrating poor in vitro activity for most available antifungals. Currently, triple therapy with intravenous voriconazole, liposomal amphotericin B, and fosmanogepix is recommended.
Efforts to understand the source of this outbreak and optimal treatment approaches are ongoing, but infectious diseases physicians should be aware of available treatment recommendations. New information will be available on CDC's website.
