RESUMO

A comprehensive understanding of gut microbiota in a clearly defined group of healthy individuals is essential when making meaningful comparisons with various diseases. The Mediterranean diet (MD), renowned for its potential health benefits, and the influence of adherence thereto on gut microbiota have become a focus of research. Our aim was to elucidate the impact of adherence to the MD on gut microbiota composition in a well-defined cohort. In this prospective study, healthy volunteers completed a questionnaire to provide demographic data, medical history, and dietary intake. Adherence was evaluated using the Med-DQI. The V4 region of the 16S rRNA gene was sequenced. Analysis of sequencing data and statistical analysis were performed using MOTHUR software and R. The study included 60 patients (51.7% females). Adherence correlated with alpha diversity, and higher values were recorded in good adherers. Good adherers had a higher abundance of Paraprevotella and Bacteroides (p < 0.001). Alpha diversity correlated inversely with fat intake and positively with non-starch polysaccharides (NSPs). Evenness correlated inversely with red meat intake and positively with NSPs. Predicted functional analysis highlighted metabolic pathway differences based on adherence to the MD. In conclusion, our study adds useful information on the relationship between the MD and the gut microbiome.

RESUMO

The incidence and recent trends of candidemia and the contribution of the COVID-19 pandemic to its evolution are not well documented. The catheter is a major focus of Candida spp. infections, but the methods used to confirm the origin of candidemia are still based on the data generated for bacterial infection. The presence of Candida spp. on the tip of a removed catheter is the gold standard for confirmation but it is not always possible to remove it. Conservative methods, without catheter removal, have not been specifically studied for microorganisms whose times of growth are different from those of bacteria and therefore these results are not applicable to candidemia. The different Candida species do not have a particular tropism for catheter colonization and fungal biomarkers have not yet been able to contribute to the determination of the origin of candidemia. Techniques such Candida T2 Magnetic Resonance (T2MR) has not yet been applied for this purpose. Finally, there is not yet a consensus of how to proceed when Candida spp. is isolated from an extracted catheter and blood cultures obtained from simultaneous peripheral veins are negative. In this lack of firm data, a group of experts has formulated a series of questions trying to answer them based on the literature, indicating the current deficiencies and offering their own opinion. All authors agree with the conclusions of the manuscript and offer it as a position and discussion paper. (AU)


La incidencia y las tendencias recientes de la candidemia y la contribución de la pandemia de COVID-19 a su evolución no están bien documentadas. El catéter es uno de los principales focos de infecciones por Candida spp., pero los métodos empleados para confirmar el origen de la candidemia siguen basándose en los datos generados para la infección bacteriana. La presencia de Candida spp. en la punta de un catéter retirado es el método de referencia para la confirmación, pero no siempre es posible proceder a dicha retirada. Los métodos conservadores, sin retirada del catéter, no han sido estudiados específicamente para microorganismos cuyos tiempos de crecimiento son diferentes a los de las bacterias y, por tanto, estos resultados no son aplicables a la candidemia. Las diferentes especies de Candida spp. no tienen un tropismo particular para la colonización del catéter y los biomarcadores fúngicos, aún no han podido contribuir a la determinación del origen de la candidemia. Técnicas como la resonancia magnética T2MR todavía no se ha empleado para este fin. Por último, todavía no existe un consenso sobre cómo proceder cuando se aísla Candida spp. en un catéter extraído y los hemocultivos obtenidos por venas periféricas simultáneas son negativos. Ante esta falta de datos firmes, un grupo de expertos ha formulado una serie de preguntas y ha tratado de responderlas en base a la literatura, indicando las carencias presentes y ofreciendo su propia opinión. Todos los autores están de acuerdo con las conclusiones del manuscrito y lo ofrecen como documento de posición y discusión. (AU)

RESUMO

INTRODUCTION: The epidemiological evolution of bloodstream infections (BSIs) in the last decade is not clearly defined. Our aim was to analyze the changes in the workload in our institution and to describe the evolution of the incidence and etiology of BSIs in a 12-year period, including the COVID-19 pandemic. METHODS: All blood cultures received in the laboratory of a tertiary general hospital between 2010 and 2021 were analyzed. Bloodstream infection episodes refer to each episode of bacteremia or fungemia in each patient. Incidence rates per 1000 admissions and per 100,000 population were calculated. RESULTS: No significant changes in the incidence of BSI episodes/1000 admissions were observed (mean, 31.1), while estimated population-based incidences showed declining trends (mean, 182.8/100,000 inhabitants). There was a slight increase in BSI episodes per 1000 admissions caused by Gram-negatives (mean, 16.6/1000 admissions) and E. coli was the most frequent pathogen (mean, 8.5/1000 admissions). There was no significant rise in episodes caused by ESBL- and carbapenemase-producing E. coli or K. pneumoniae, with a decline in those caused by methicillin-resistant S. aureus. A spike in BSI episodes, fungal BSIs and catheter-related infections was detected in 2020, during the COVID-19 outbreak. CONCLUSIONS: No clear increase in the incidence of BSI episodes was detected in our center over this period. Gram-negatives are the most frequent etiology, with no clear rise in antimicrobial resistance phenotypes. The COVID-19 pandemic accounted for a small increase in BSI episodes in 2020, probably related to the increase of catheter-related infections.

RESUMO

PURPOSE OF REVIEW: There are aspects of skin and soft tissue infections (SSTIs) that remain unresolved, such as current numbers, classification criteria, how best to define severity and predict the outcome, what diagnostic tests to perform, what new treatment options are available, or what the duration of antibiotic treatment should be. We have reviewed the literature over the last 18 months to clarify these issues and provide our opinion. RECENT FINDINGS: SSTIs are common and among the top 10 most frequent infections worldwide. They represent a burden on the healthcare system and have a major impact on the quality of life of patients. Regarding classification, the Infectious Diseases Society of America (IDSA) provides a practical guide that distinguishes between uncomplicated and complicated infections, acute and chronic wound infections, and necrotising and nonnecrotizing infections based on skin extension and tissue necrosis. With new microbiological and imaging diagnostic techniques, SSTIs can now be better diagnosed. New PCR techniques are available, and mass spectrometry can be applied to samples collected in liquid transport media. Moreover, new treatment methods such as photodynamic therapy, reactive oxygen, and phages are emerging. SSTI patients can be treated with shorter antibiotic courses if they receive an active drug with good tissue penetration. Antibiotic treatment in necrotizing infections can be shortened to 48 h after the last debridement. SUMMARY: SSTIs remain a challenge regarding rapid and accurate diagnosis and clinical management.

RESUMO

Clostridioides difficile infection (CDI) remains a considerable challenge to healthcare systems worldwide. Although CDI represents a significant burden on healthcare systems in Europe, few studies have attempted to estimate the consumption of resources associated with CDI in Europe. The reported extra costs attributable to CDI vary widely according to the definitions, design, and methodologies used, making comparisons difficult to perform. In this chapter, the economic burden of healthcare facility-associated CDI in Europe will be assessed, as will other less explored areas such as the economic burden of recurrent CDI, community-acquired CDI, pediatric CDI, and CDI in outbreaks.

RESUMO

BACKGROUND: At some point in their lives, many people will require major heart surgery (MHS). Patients are generally older adults with various risk factors for infection. However, the incidence of infection after MHS is poorly known, as reported infection data are frequently biased due to different factors like the surgical procedure, postoperative timing, and infectious syndromes or etiologic agents, among others. In addition, most patient data are retrospectively obtained. PURPOSE AND METHODS: Data were prospectively collected regarding the incidence of all nosocomial infections produced from the time of surgery to hospital discharge in a cohort of 800 adults consecutively undergoing a MHS procedure. RESULTS: During postoperative hospitalization, 124 of the 800 participants developed one or more infections (15.5%): during their ICU stay in 68 patients (54.8%), during their stay on the general ward post ICU in 50 (40.3%), and during their stay in both wards in 6 (4.8%). The most common infections were pneumonia (related or not to mechanical ventilation), surgical site and bloodstream. As etiological agents, 193 pathogens were isolated: mostly Gram-negative bacilli (54.4%), followed by Gram-positive bacteria (30%), viruses (4.6%) and fungi (1.5%). In our cohort, all-cause mortality was recorded in 33 participants (4.1%) and 9 infection-related deaths (1.1%) were produced. Among subjects who developed infections, overall mortality was 13.7% and in those who did not, this was only 2.3%. CONCLUSION: Infection following MHS remains frequent and severe. Our data suggest that hospital-acquired infection studies should consider episodes of infection in all populations during their entire hospital stay and not only those related to specific clinical syndromes or acquired while the patient is in intensive care.

RESUMO

Nursing homes (NH) conceptually should look as much like a home as possible. However NH have unquestionable similar ities with a nosocomium as they are places where many pa tients with underlying diseases and comorbidities accumulate. There is evidence of transmission of microorganisms between residents and between residents and caregivers. We have not found any recommendations specifically aimed at the prevention of nosocomial infections in NH by the major Public Health Agencies and, therefore, the Health Sciences Foundation (Fundación de Ciencias de la Salud) has convened a series of experts and 14 Spanish scientific societies to discuss recommendations that could guide NH personnel in establishing written programs for the control and reduction of these infections. The present document is the result of these deliberations and contains suggestions for establishing such control programs on a voluntary and flexible basis in NH. We also hope that the document can help the health authorities to encourage this control activity in the different territorial areas of Spain. In our opinion, it is necessary to draw up a written plan and establish the figure of a coordinator or person respon sible for implementing these projects. The document includes measures to be implemented and ways of quantifying the real ity of different problems and of monitoring the impact of the measures established (AU)


Las residencias de ancianos (NH) aunque conceptualmente deberían parecerse lo más posible a un hogar, tienen induda bles similitudes con un nosocomio ya que son lugares donde se acumulan muchos pacientes con enfermedades de base y comorbilidades y donde la transmisión de microorganismos en tre residentes y entre residentes y cuidadores es frecuente. No hemos encontrado recomendaciones específicamente dirigidas a la prevención de las infecciones nosocomiales en NH por parte de las principales Agencias de Salud Pública y, por ello, la Fundación de Ciencias de la Salud ha convocado a una serie de expertos y a 14 sociedades científicas españolas para de batir recomendaciones que puedan orientar al personal de las NH en el establecimiento de programas escritos para el control y reducción de estas infecciones. El presente documento es el resultado de estas deliberaciones y contiene sugerencias para establecer dichos programas de control de forma voluntaria y flexible. También esperamos que el documento pueda ayudar a las autoridades sanitarias a fomentar esta actividad de control en los distintos ámbitos territoriales de España. En nuestra opi nión, es necesario elaborar un plan por escrito y establecer la figura de un coordinador o responsable de la ejecución de estos proyectos. El documento incluye las medidas a implantar y las formas de cuantificar la realidad de los diferentes problemas y de monitorizar el impacto de las medidas establecidas (AU)

RESUMO

PURPOSE OF REVIEW: To update the management of severe Acinetobacter baumannii infections (ABI), particularly those caused by multi-resistant isolates. RECENT FINDINGS: The in vitro activity of the various antimicrobial agents potentially helpful in treating ABI is highly variable and has progressively decreased for many of them, limiting current therapeutic options. The combination of more than one drug is still advisable in most circumstances. Ideally, two active first-line drugs should be used. Alternatively, a first-line and a second-line drug and, if this is not possible, two or more second-line drugs in combination. The emergence of new agents such as Cefiderocol, the combination of Sulbactam and Durlobactam, and the new Tetracyclines offer therapeutic options that need to be supported by clinical evidence. SUMMARY: The apparent limitations in treating infections caused by this bacterium, the rapid development of resistance, and the serious underlying situation in most cases invite the search for alternatives to antibiotic treatment, the most promising of which seems to be bacteriophage therapy.

RESUMO

Introduction: Clostridioides difficile infection (CDI) is the main cause of nosocomial diarrhoea in developed countries. Recurrent CDI (R-CDI), which affects 20%-30% of patients and significantly increases hospital stay and associated costs, is a key challenge. The main objective of this study was to explore the role of the microbiome and calprotectin levels as predictive biomarkers of R-CDI. Methods: We prospectively (2019-2021) included patients with a primary episode of CDI. Clinical data and faecal samples were collected. The microbiome was analysed by sequencing the hypervariable V4 region of the 16S rRNA gene on an Illumina Miseq platform. Results: We enrolled 200 patients with primary CDI, of whom 54 developed R-CDI and 146 did not. We analysed 200 primary samples and found that Fusobacterium increased in abundance, while Collinsella, Senegalimassilia, Prevotella and Ruminococcus decreased in patients with recurrent versus non-recurrent disease. Elevated calprotectin levels correlated significantly with R-CDI (p=0.01). We built a risk index for R-CDI, including as prognostic factors age, sex, immunosuppression, toxin B amplification cycle, creatinine levels and faecal calprotectin levels (overall accuracy of 79%). Discussion: Calprotectin levels and abundance of microbial genera such as Fusobacterium and Prevotella in primary episodes could be useful as early markers of R-CDI. We propose a readily available model for prediction of R-CDI that can be applied at the initial CDI episode. The use of this tool could help to better tailor treatments according to the risk of R-CDI.

RESUMO

BACKGROUND: Little is known about the incidence of influenza among admissions to the cardiac intensive care unit (C-ICU), accuracy of clinical suspicion, and influenza vaccination uptake. We evaluated the incidence of influenza at C-ICU admission during the influenza season, potential underdiagnosis, and vaccination uptake. METHODS: Prospective study at five C-ICUs during the 2017-2020 influenza seasons. A nasopharyngeal swab was collected at admission from patients who consented (n = 788). Testing was with Xpert®XpressFlu/RSV. RESULTS: Influenza was detected in 43 patients (5.5%) (40 FluA; 3 FluB) and clinically suspected in 27 (62.8%). Compared to patients without influenza, patients with influenza more frequently had heart failure (37.2% vs 22.8%, P = 0.031), previous contact with relatives with influenza-like illnesses (23.3% vs 12.5%, P = 0.042), antimicrobial use (67.4% vs 23.2%, P <0.01), and need for mechanical ventilation (25.6% vs 14.5%, P = 0.048). Patients received oseltamivir promptly. We found no differences in mortality (11.6% vs 5.2%, P = 0.076). Patients with influenza more frequently had myocarditis (9.3% vs 0.9%, P <0.01) and pericarditis (7.0% vs 0.8%, P = 0.01). Overall, 43.0% of patients (339/788) were vaccinated (51.9% of those with a clear indication [303/584]). CONCLUSION: Influenza seems to be a frequently underdiagnosed underlying condition in admissions to the C-ICU. Influenza should be screened for at C-ICU admission during influenza epidemics.

RESUMO

IMPORTANCE: This study on bacteremic nosocomial pneumonia (bNP) demonstrates the importance of this condition both in patients undergoing and not undergoing mechanical ventilation. Staphylococcus aureus, Enterobacterales, and non-fermenting Gram-negative bacilli are all causative agents in ventilator-associated pneumonia (VAP) and hospital-acquired pneumonia (HAP), with a predominance of S. aureus in HAP and of Pseudomonas aeruginosa in VAP. Mortality in this condition is very high. Therefore, new therapeutic and preventive approaches should be sought.

RESUMO

Background: Patients who acquire infective endocarditis (IE) following contact with the healthcare system, but outside the hospital, are classified as having non-nosocomial healthcare-associated IE (HCIE). Our aim was to characterize HCIE and establish whether its etiology, diagnosis, and therapeutic approach suggest it should be considered a distinct entity. Methods: This study retrospectively analyzes data from a nationwide, multicenter, prospective cohort including consecutive cases of IE at 45 hospitals across Spain from 2008 to 2021. HCIE was defined as IE detected in patients in close contact with the healthcare system (eg, patients receiving intravenous treatment, hemodialysis, or institutionalized). The prevalence and main characteristics of HCIE were examined and compared with those of community-acquired IE (CIE) and nosocomial IE (NIE) and with literature data. Results: IE was diagnosed in 4520 cases, of which 2854 (63%) were classified as CIE, 1209 (27%) as NIE, and 457 (10%) as HCIE. Patients with HCIE showed a high burden of comorbidities, a high presence of intravascular catheters, and a predominant staphylococcal etiology, Staphylococcus aureus being identified as the most frequent causative agent (35%). They also experienced more persistent bacteremia, underwent fewer surgeries, and showed a higher mortality rate than those with CIE (32.4% vs 22.6%). However, mortality in this group was similar to that recorded for NIE (32.4% vs 34.9%, respectively, P = .40). Conclusions: Our data do not support considering HCIE as a distinct entity. HCIE affects a substantial number of patients, is associated with a high mortality, and shares many characteristics with NIE.

RESUMO

A progressively increasing percentage of the elderly live during the last years of their lives in nursing homes. Although these institutions are intended to mimic life at home as much as possible, they have characteristics that make them quite similar to a “nosocomiun”, i.e. an establishment for the treatment of the sick. The very coexistence among the elderly, the fact of sharing caregivers and the very significant exposure to third parties, together with the frequent predisposing diseases to infection in this population, make infection frequent among residents and also easily transmissible. This leads us to ask what can be done to prevent infection in this environment and more specifically what is the state of the art of the matter in a Western European nation such as ours. The Board of Trustees of the Health Sciences Foundation has asked itself a series of questions on the subject of infection prevention in Nursing Homes, the structure of procedures, the legislation available, compliance with the measures indicated, the best indicators of the processes and therefore, the need to promote in Spain a document of recommendations to avoid infections in this poplation whose morbidity and mortality need not be highlighted. To this end, a multidisciplinary group of experts in different aspects of this problem has been convened and asked the proposed questions. The questions were discussed by the group as a whole and led to a series of conclusions agreed upon by the participants. The results of the meeting are reported below (AU)


Un porcentaje progresivamente creciente de las personas mayores viven durante los últimos años de su vida en residencias de ancianos. Dichas instituciones, aunque pretenden remedar lo más posible la vida en el hogar, tienen características que las hace bastante parecidas a un nosocomio, es decir a un establecimiento destinado al tratamiento de enfermos. La propia convivencia entre los ancianos, el hecho de compartir cuidadores y la exposición muy importante a terceras personas, junto con las frecuentes enfermedades predisponentes a la infección de esta población, hacen que la infección sea frecuente entre los residentes y que además sea fácilmente transmisible. Esto nos lleva a preguntarnos qué puede hacerse para prevenir la infección en este medio y más concretamente cuál es el estado del arte de la cuestión en una nación de Europa Occidental como la nuestra. El patronato de la Fundación de Ciencias de la Salud se ha formulado una serie de preguntas sobre el tema de la prevención de la infección en las Residencias de Mayores, la estructura de la misma, la legislación vigente, el cumplimiento de las medidas indicadas, los indicadores de los procesos y por ende, la necesidad de fomentar en España un documento de recomendaciones para evitar infecciones en esta población cuya morbilidad y mortalidad no necesitan ser resaltadas. Para ello, se ha convocado a un grupo multidisciplinar de expertos en distintos aspectos de este problema a los que se les han formulado las preguntas propuestas. Las preguntas han sido discutidas por el grupo en su conjunto y han conducido a una serie de conclusiones consensuadas entre los participantes. Pasamos, a continuación a relatar los resultados de la reunión (AU)

RESUMO

Introduction: Clostridioides difficile infection (CDI) is the main cause of nosocomial diarrhea in developed countries. A key challenge in CDI is the lack of objective methods to ensure more accurate diagnosis, especially when differentiating between true infection and colonization/diarrhea of other causes. The main objective of this study was to explore the role of the microbiome as a predictive biomarker of CDI. Methods: Between 2018 and 2021, we prospectively included patients with CDI, recurrent CDI (R-CDI), non-CDI diarrhea (NO-CDI), colonization by C. difficile, and healthy individuals. Clinical data and fecal samples were collected. The microbiome was analyzed by sequencing the hypervariable V4 region of the 16S rRNA gene on an Illumina Miseq platform. The mothur bioinformatic pipeline was followed for pre-processing of raw data, and mothur and R were used for data analysis. Results: During the study period, 753 samples from 657 patients were analyzed. Of these, 247 were from patients with CDI, 43 were from patients colonized with C. difficile, 63 were from healthy individuals, 324 were from NOCDI, and 76 were from R-CDI. We found significant differences across the groups in alpha and beta diversity and in taxonomic abundance. We identified various genera as the most significant biomarkers for CDI (Bacteroides, Proteus, Paraprevotella, Robinsoniella), R-CDI (Veillonella, Fusobacterium, Lactobacillus, Clostridium sensu stricto I), and colonization by C. difficile (Parabacteroides, Faecalicoccus, Flavonifractor, Clostridium XVIII). Discussion: We observed differences in microbiome patterns between healthy individuals, colonized patients, CDI, R-CDI, and NOCDI diarrhea. We identified possible microbiome biomarkers that could prove useful in the diagnosis of true CDI infections. Further studies are warranted.

RESUMO

With the approval and development of narrow-spectrum antibiotics for the treatment of Clostridioides difficile infection (CDI), the primary endpoint for treatment success of CDI antibiotic treatment trials has shifted from treatment response at end of therapy to sustained response 30 days after completed therapy. The current definition of a successful response to treatment (three or fewer unformed bowel movements [UBMs] per day for 1-2 days) has not been validated, does not reflect CDI management, and could impair assessments for successful treatment at 30 days. We propose new definitions to optimise trial design to assess sustained response. Primarily, we suggest that the initial response at the end of treatment be defined as (1) three or fewer UBMs per day, (2) a reduction in UBMs of more than 50% per day, (3) a decrease in stool volume of more than 75% for those with ostomy, or (4) attainment of bowel movements of Bristol Stool Form Scale types 1-4, on average, by day 2 after completion of primary CDI therapy (ie, assessed on day 11 and day 12 of a 10-day treatment course) and following an investigator determination that CDI treatment can be ceased.

RESUMO

The use of venoarterial (VA) extracorporeal membrane oxygenation therapy (ECMO) in patients admitted to cardiac intensive care units (CICU) has increased. Data regarding infections in this population are scarce. In this retrospective study, we analyzed the risk factors, outcome, and predictors of in-hospital mortality due to nosocomial infections in patients with ECMO admitted to a single coronary intensive care unit between July 2013 and March 2019 treated with VA-ECMO for >48 h. From 69 patients treated with VA-ECMO >48 h, (median age 58 years), 29 (42.0%) patients developed 34 episodes of infections with an infection rate of 0.92/1000 ECMO days. The most frequent were ventilator-associated pneumonia (57.6%), tracheobronchitis (9.1%), bloodstream infections (9.1%), skin and soft tissue infections (9.1%), and cytomegalovirus reactivation (9.1%). In-hospital mortality was 47.8%, but no association with nosocomial infections was found (p = 0.75). The number of days on ECMO (OR 1.14, 95% CI 1.01-1.30, p = 0.029) and noninfectious complications were higher in the infected patients (OR: 3.8 95% CI = 1.05-14.1). A higher baseline creatinine value (OR: 8.2 95% CI = 1.12-60.2) and higher blood lactate level at 4 h after ECMO initiation (OR: 2.0 95% CI = 1.23-3.29) were significant and independent risk factors for mortality. Conclusions: Nosocomial infections in medical patients treated with VA-ECMO are very frequent, mostly Gram-negative respiratory infections. Preventive measures could play an important role for these patients.

RESUMO

The Health Sciences Foundation has assembled a multidisciplinary group around a series of questions about the impact of the COVID-19 pandemic on the mental health of the general population and specific groups within that population, particularly healthcare workers.In the general population, the most prevalent mental disorders have been anxiety, sleep disorders and affective disorders, primarily depression. There has been a considerable increase in suicidal behavior, especially in young women and men over 70 years of age. There has been an increase in alcohol abuse and nicotine, cannabis and cocaine use. In contrast, the use of synthetic stimulants during periods of confinement has decreased. With regard to non-substance addictions, gambling was very limited, pornography consumption increased significantly and there was an increase in compulsive shopping and the use of video games.Particularly vulnerable groups include adolescents and patients with autism spectrum disorders. Healthcare workers suffered an increase in depression, anxiety and post-traumatic stress, especially those who were exposed during the early stages of the pandemic. Female sex, being a nurse, proximity to patients with COVID-19, working in a rural environment and having previous psychiatric or organic illnesses were some of the most frequently repeated factors in various studies in this population group.The media have shown a good degree of knowledge about these problems and have dealt with them frequently and from the point of view of ethics, crisis situations, such as the one experienced, have triggered not only physical but also moral claudications.

La Fundación de Ciencias de la Salud ha reunido a un grupo multidisciplinar alrededor de una serie de preguntas sobre el impacto de la pandemia de COVID-19 en la salud mental de la población en general y de grupos específicos de dicha población, particularmente los trabajadores sanitarios.En la población general, los trastornos mentales más prevalentes han sido la ansiedad, los trastornos del sueño y los trastornos afectivos, fundamentalmente la depresión. Se ha producido un aumento considerable de la conducta suicida, especialmente en mujeres jóvenes y varones mayores de 70 años. Se ha incrementado el abuso de alcohol y los consumos de nicotina, cannabis y cocaína.Por el contrario, ha disminuido el consumo de los estimulantes sintéticos durante los periodos de confinamiento. Respecto a las adicciones sin sustancia, el juego de apuestas quedó muy limitado, el consumo de pornografía experimentó un incremento notable y hubo un aumento de la compra compulsiva y del uso de videojuegos.En cuanto a grupos particularmente vulnerables hay que destacar el de los adolescentes y el de los enfermos con trastornos del espectro autista. Los sanitarios han sido un grupo especialmente vulnerable, en particular los que estuvieron expuestos durante las primeras fases de la pandemia. El sexo femenino, el ser enfermera, la proximidad a los pacientes con COVID-19, el ejercicio en un medio rural y padecer enfermedades psiquiátricas u orgánicas previas, fueron algunos de los factores más frecuentemente repetidos en diversos estudios en este grupo de población. Depresión, ansiedad y estrés post-traumático fueron los trastornos más frecuentes.Los medios de comunicación han mostrado un buen grado de conocimiento sobre estos problemas y los han tratado con frecuencia. Desde el prisma de la ética, las situaciones de crisis, como la vivida, han desencadenado claudicaciones no solo físicas sino también morales. (AU)

RESUMO

Background: We aimed to describe the frequency of use and effectiveness of bezlotoxumab (BZX) and fecal microbiota transplantation (FMT) in patients with Clostridioides difficile infection (CDI) in real-world practice. Methods: This was a retrospective study conducted in a university hospital in which adult patients treated with BZX or FMT from January 2018 to April 2021 were included. The primary objective was to evaluate the effectiveness of BZX and FMT in preventing early (within 8 weeks) and late (within 1 year) CDI recurrences (rCDI). A multivariate analysis of risk factors for early recurrence was performed. Results: Of 1377 consecutive CDI episodes, 117 (8.5%) received BZX or FMT, with full information available for 100 of the episodes: 51 received BZX, and 49 received FMT. BZX was used mostly in immunosuppressed patients (66.7%) and in first episodes or first recurrences in 70.6% of the cases. FMT was prescribed only in CDI recurrences. Despite the different conditions of the patients, there were no significant differences between BZX and FMT in preventing early rCDI (19.6% vs 24.5%; P = .55) or late rCDI (9.8% vs 18.4%; P = .31). In the multivariate analysis, risk factors for recurrence were presence of ≥2 previous rCDI episodes (odds ratio [OR], 2.90; 95% CI, 1.03-8.63) and use of non-CDI antibiotics (OR, 3.45; 95% CI, 1.24-9.57). Conclusions: BZX and FMT were infrequently used in real-world practice. Both treatments had similar effectiveness in preventing CDI recurrence despite their application to different populations.

RESUMO

PURPOSE OF REVIEW: Our purpose is to review the state-of-the-art on the management of skin and soft tissue infections (SSTI) in emergency departments (ED).Although the information is scarce, SSTI may account for 3-30% of all cases presenting to an ED, of which 25-40% require hospital admission.SSTI include very different entities in aetiology, location, pathogenesis, extension, and severity. Therefore, no single management can be applied to them all. A simple approach is to classify them as non-purulent, purulent, and necrotising, to which a severity scale based on their systemic repercussions (mild, moderate, and severe) must be added.The initial approach to many SSTIs often requires no other means than anamnesis and physical examination, but imaging tests are an indispensable complement in many other circumstances (ultrasound, computerized tomography, magnetic resonance imaging…). In our opinion, an attempt at etiological filiation should be made in severe cases or where there is suspicion of a causality other than the usual one, with tests based not only on cultures of the local lesion but also molecular tests and blood cultures. RECENT FINDINGS: Recent contributions of interest include the value of bedside ultrasound and the potential usefulness of biomarkers such as thrombomodulin to differentiate in early stages the presence of necrotising lesions not yet explicit.New antimicrobials will allow the treatment of many of these infections, including severe ones, with oral drugs with good bioavailability and for shorter periods. SUMMARY: The ED has an essential role in managing SSTIs, in their classification, in decisions on when and where to administer antimicrobial treatment, and in the rapid convening of multidisciplinary teams that can deal with the most complex situations.

RESUMO

We do not know the precise figure for solid organ tumors diagnosed each year in Spain and it is therefore difficult to calculate whether there has been a decrease in cancer diagnoses as a consequence of the pandemic. Some indirect data suggest that the pandemic has worsened the stage at which some non-hematological neoplasms are diagnosed. Despite the lack of robust evidence, oncology patients seem more likely to have a poor outcome when they contract COVID-19. The antibody response to infection in cancer patients will be fundamentally conditioned by the type of neoplasia present, the treatment received and the time of its administration.In patients with hematological malignancies, the incidence of infection is probably similar or lower than in the general population, due to the better protective measures adopted by the patients and their environment. The severity and mortality of COVID-19 in patients with hematologic malignancies is clearly higher than the general population. Since the immune response to vaccination in hematologic patients is generally worse than in comparable populations, alternative methods of prevention must be established in these patients, as well as actions for earlier diagnosis and treatment.Campaigns for the early diagnosis of malignant neoplasms must be urgently resumed, post-COVID manifestations should be monitored, collaboration with patient associations is indisputable and it is urgent to draw the right conclusions to improve our preparedness to fight against possible future catastrophes.

No conocemos con precisión la cifra nacional de tumores sólidos diagnosticados en España anualmente y por tanto se hace difícil calcular si ha habido una disminución de diagnósticos de cáncer como consecuencia de la pandemia. Algunos datos indirectos permiten sospechar que la pandemia ha empeorado el estadio en que se diagnostican algunas neoplasias no hematológicas. A pesar de no existir una evidencia robusta, los pacientes oncológicos presentan una mayor tendencia a tener una mala evolución cuando contraen COVID-19. La respuesta de anticuerpos frente a la infección en pacientes con cáncer va a estar condicionada fundamentalmente por el tipo de neoplasia presente, el tratamiento recibido y el momento de su administración.En pacientes con hemopatías malignas la incidencia de infección es probablemente similar o inferior a la de la población general, debido a las mejores medidas de protección adoptadas por los pacientes y su entorno. La gravedad y letalidad de la COVID-19 en pacientes con hemopatías malignas es claramente más elevada que en la población general. Dado que la respuesta inmune a la vacunación es peor que en poblaciones comparables, hay que establecer métodos alternativos de prevención en estos pacientes, así como planes de diagnóstico y tratamiento precoces.Hay que retomar las campañas de diagnóstico precoz de neoplasias malignas con urgencia, vigilar las manifestaciones post-COVID, colaborar con las asociaciones de pacientes y hacer planes urgentes para hacer frente con más eficiencia a potenciales catástrofes futuras.
