Infective endocarditis due to Citrobacter koseri following testicular trauma: case report and literature review.

Infective endocarditis (IE) is a condition with low prevalence but high mortality rates within intensive care units. Microbiologically, most cases are attributed to Gram-positive cocci, while Gram-negative bacilli are less commonly involved. This case report describes a patient with IE caused by Citrobacter koseri (C. koseri) with secondary bacteremia due to blunt testicular trauma and epididymitis. We conducted a review of the literature to assess the clinical and associated risk factors of this underreported condition. Elderly and urinary tract infections could be associated with this entity. Cefazolin was used as the final targeted treatment. The use of precision medicine in IE is required for specific interventions.

Infection of the heart valve from testicular injury: a case study and review of medical literature Infective endocarditis (IE) is a serious but rare infection that can lead to death, especially in intensive care units. Typically, it's caused by certain types of bacteria, but our case study focuses on a patient whose IE was caused by a less common bacterium called Citrobacter koseri (C. koseri). This infection occurred after the patient experienced blunt trauma to the testicles, leading to a bloodstream infection. We looked at other similar cases in medical literature and found that older age and urinary tract infections might increase the risk of this type of IE. In this case, IE caused by this unusual bacteria was treated with cefazolin.

Outcomes of ECMO support with polypropylene membrane during pandemic times: a retrospective cohort study.

BACKGROUND: The SARS-CoV-2 pandemic resulted in shortages of supplies, which limited the use of extracorporeal membrane oxygenation (ECMO) support. As a contingency strategy, polypropylene (PP) oxygenation membranes were used. This study describes the clinical outcomes in patients on ECMO with PP compared to poly-methylpentene (PMP) oxygenation membranes. METHODS: Retrospective cohort of patients in ECMO support admitted between 2020 and 2021. RESULTS: A total of 152 patients with ECMO support were included, 71.05% were men with an average age of 42 (SD 9.91) years. Veno-venous configuration was performed in 75.6% of cases. The PP oxygenation membranes required more changes 22 (63.1%), than the PMP Sorin® 24 (32,8%) and Euroset® 15 (31,9%) (p.0.022). The main indication for membrane change was low oxygen transfer for PP at 56.2%, Sorin® at 50%, and Euroset® at 14.8%. Renal replacement therapy was the most frequent complication with PP membrane in 22 patients (68.7%) Sorin® 25 patients (34.2%), and Euroset® 15 patients (31.9%) (p 0.001) without statistically significant differences in mortality. CONCLUSION: PP oxygenation membranes was a useful and feasible strategy. It allowed a greater disponibility of ECMO support for critically ill in a situation of great adversity during the SARS-CoV-2 pandemic.

Oxygen Debt as Predictor of Mortality and Multiple Organ Dysfunction Syndrome in Severe COVID-19 Patients: A Retrospective Study.

Background: Oxygen debt (DEOx) represents the disparity between resting and shock oxygen consumption (VO2) and is associated with metabolic insufficiency, acidosis, severity, and mortality. This study aimed to assess the reliability of DEOx as an indirect quantitative measure for predicting multiple organ dysfunction syndrome (MODS) and 28-day mortality in patients admitted to the intensive care unit (ICU) with respiratory syndrome severe acute coronavirus type 2 (SARS-CoV-2) infection, in comparison to the Acute Physiology and Chronic Health Evaluation II (APACHE II), sepsis-related organ failure assessment (SOFA), and 4C scores. Methods: A retrospective cohort study was conducted, including ICU patients with SARS-CoV-2 infection between 2020 and 2021. Clinical data were extracted from the EPIMED Monitor Database®. APACHE II, SOFA, and 4C scores were calculated upon ICU admission, and their accuracy in predicting 28-day mortality and MODS was compared to DEOx. Multivariate logistic regression analysis was performed to analyze the outcome variables. Results: 708 patients were included, with a mortality rate of 44.4%. DEOx value was 11.16 ml O2/kg. The mean age was 58.7 years. Multivariate analysis showed that DEOx was independently associated with mortality, intubation, and renal injury. Each point increase in creatinine was associated with a higher risk of MODS. To determine the precision of the scores, area under the receiver operating characteristic curves (AUROC) analysis was performed with weak discrimination and similar behavior for the primary outcomes. The most accurate scale for mortality and MODS was 4C with an AUC of 0.683 and APACHE II with an AUC of 0.814, while that of the AUROC of DEOx was 0.612 and 0.646, respectively. Conclusions: DEOx showed similar predictive value to established scoring systems in critically ill patients with SARS-CoV-2 infection. The correlation of DEOx with these scores may facilitate early intervention in critically ill patients.

Neurological outcomes and quality of life in post-cardiac arrest patients with return of spontaneous circulation supported by ECMO: A retrospective case series.

Post-cardiac arrest brain injury constitutes a significant contributor to morbidity and mortality, leading to cognitive impairment and subsequent disability. Individuals within this patient cohort grapple with uncertainty regarding the potential advantages of extracorporeal life support (ECMO) cannulation. This study elucidates the neurological outcomes and quality of life of post-cardiac arrest patients who attained spontaneous circulation and underwent ECMO cannulation. This is a retrospective case study within a local context, the research involved 32 patients who received ECMO support following an intrahospital cardiac arrest with return of spontaneous circulation (ROSC). An additional 32 patients experienced cardiac arrest with ROSC before undergoing cannulation. The average age was 41 years, with the primary causes of cardiac arrest identified as acute coronary syndrome (46.8%), pulmonary thromboembolism (21.88%), and hypoxemia (18.7%). The most prevalent arrest rhythm was asystole (37.5%), followed by ventricular fibrillation (34.4%). The mean SOFA score was 7 points (IQR 6.5-9), APACHE II score was 12 (IQR 9-16), RESP score was -1 (IQR -1 to -4) in cases of respiratory ECMO, and SAVE score was -3 (IQR -5 to 2) in cases of cardiac ECMO. Overall survival was 71%, and at 6 months, the Barthel score was 75 points, modified Rankin score was 2, cerebral performance categories score was 1, and the SF-12 had an average score of 30. Notably, there were no significant associations between the time, cause, or rhythm of cardiac arrest and neurological outcomes. Importantly, cardiac arrest is not a contraindication for ECMO cannulation. A meticulous assessment of candidates who have achieved spontaneous circulation after cardiac arrest, considering the absence of early signs of poor neurological prognosis, is crucial in patient selection. Larger prospective studies are warranted to validate and extend these findings.

Lesión cerebral post paro cardiaco: aspectos médicos, éticos y legales / Brain injury after cardiac arrest: Medical, ethical and legal issues disorder

RESUMEN Los sobrevivientes de la reanimación cardiopulmonar posterior a un paro cardiaco pueden tener un amplio rango de desenlaces y van desde recuperación neurológica completa, estado de vigilia sin respuesta, compromiso cognoscitivo diverso o la muerte. La lesión del tejido cerebral se presenta inmediatamente después del paro cardíaco, durante la reanimación y al retornar la circulación espontánea. La severidad y duración de la noxa isquémica determinarán el devenir neurológico. El examen clínico es el punto de partida en el abordaje multimodal del neuropronóstico. Se debe complementar con electroencefalograma, potenciales evocados somatosensoriales, neuroimágenes y biomar-cadores séricos. Entre un 10 a 15% de los pacientes con lesión cerebral posterior al paro cardiaco evolucionan hacia muerte por criterios neurológicos y son potenciales candidatos a la donación de órganos. Un retiro temprano de las terapias de sostenimiento de vida puede malograr la posibilidad de un potencial donante de órganos. Se puede estimar de manera temprana qué pacientes tienen mayor riesgo de evolucionar a muerte por criterios neurológicos. El neurólogo tiene un papel protagónico en el manejo de pacientes con lesión cerebral post paro cardiaco y sus decisiones tienen implicaciones éticas y legales.

ABSTRACT People who survive cardiopulmonary resuscitation (CPR) after cardiac arrest, have a wide range of outcomes including complete neurological recovery, coma, compromised cognitive function and death. Injury of the brain parenchyma starts immediately after a cardiac arrest, during CPR and return of spontaneous circulation. The severity of the ischemic injury will define the neurological outcome. The first step needed to determine a neurological prognosis is the clinical exam, with the help of electroencephalography, somatosensory evoked potentials, neuroimaging, and serum biomarkers. Between 10 and 15% of patients with brain injury after a cardiac arrest, develop brain death and become potential candidates for organ donation. A premature withdrawal of vital support can hamper the possibility of organ donation. The patients with higher risk of developing brain death can be identified early based on neurological criteria. The neurologist has a major role in the approach of patients with brain injury after cardiac arrest and the decision making with legal and ethical consequences.

Severe gastrointestinal injury associated with SARS-CoV-2 infection: Thrombosis or Inflammation?: A retrospective case series study.

OBJECTIVES: Acute gastrointestinal injury (AGI) associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has a low incidence of complications in patients admitted to the intensive care unit (ICU). Pathophysiological knowledge related to AGI is limited, as few studies have been published on this topic. Therefore, this study was carried out to identify the clinical and histopathological features of patients with SARS-CoV-2 infection and grade IV AGI. METHODS: This is a retrospective case study of fifteen patients with SARS-CoV-2 infection and grade IV AGI who underwent emergency surgery. RESULTS: This study revealed a mortality rate of 62.5%. The most frequent gastrointestinal symptoms were abdominal distension (100%) and increased gastric residual volume (93.3%). Distended bowel loops on plain abdominal radiography (90%) and intestinal pneumatosis on computed tomography (50%) were the most frequent imaging findings. Surgical exploration revealed intestinal ischemia (66.6%) and necrosis (46.6%), and histopathology showed ischemic and liquefactive necrosis with mixed inflammatory involvement and absence of thrombosis as the cause of AGI. CONCLUSIONS: AGI associated with severe SARS-CoV-2 infection has a high mortality rate and poses a diagnostic challenge in the ICU. The complex pathophysiology and histopathological findings indicate an associated inflammatory phenomenon as the main alteration in the absence of thrombosis, as per the intestinal biopsies of the cases studied. Further clinical studies are required to gain a better understanding of this pathology.

Adherencia a la guía de manejo de sepsis severa y choque séptico en pacientes mayores de 65 años que ingresan a UCI / Adherence to the guidelines for the management of severe sepsis and septic shock in patients over 65 years of age admitted to the ICU

Introduction: The use of guidelines for goal-oriented resuscitation in patients with severe sepsis and septic shock has a positive impact on multiple organ failure and mortality outcomes. However, in patients over 65, adherence to the guidelines may be less stringent because of considerations of lower functional, cardiac, pulmonary and renal reserve. This study compares adherence to the guidelines and compliance with resuscitation goals by the healthcare staff in populations over and under 65 years of age. Objective: To determine adherence to the guidelines by the healthcare staff in the treatment of severe sepsis and septic shock in the group over 65 years of age, compared with patients under 65. Materials and methods: Observational, analytical, cross-sectional study of patients under and over 65 years of age admitted to the Intensive Care Unit (ICU) after having been diagnosed with severe sepsis and septic shock. Frequency of adherence to the guidelines was determined and a comparison of the different resuscitation goals in relation to adherence to the guidelines was made. Results: Except for adherence to early initiation of antibiotic therapy, there was better adherence to the other goals in the patients under 65 when compared to patients over 65. Adherence to the guidelines declined progressively as the number of goals increased. Conclusions: There was a lower adherence to resuscitation guidelines in the group of patients over 65 with severe sepsis and septic shock when compared with the group of patients under 65.

Introducción: El uso de guías de reanimación por metas en los pacientes con sepsis severa y choque séptico, genera un impacto benéfico en los desenlaces de disfunción orgánica múltiple y de la mortalidad, sin embargo en los pacientes mayores de 65 años, la adherencia a las guías puede ser menor, por la menor reserva funcional, cardíaca, pulmonar y renal. En el presente estudio comparamos la adherencia a la guía y el cumplimiento de las metas de reanimación por parte del personal de salud en la población mayor y menor de 65 años. Objetivo: Determinar la adherencia a las guías para el tratamiento de la sepsis severa y choque séptico por parte del personal de salud en el grupo mayor de 65 años comparado con el grupo de pacientes menores de 65 años.. Materiales y métodos: Estudio observacional analítico de corte transversal de los pacientes menores y mayores de 65 años ingresados a la Unidad de Cuidados Intensivos (UCI), con diagnóstico de sepsis severa y choque séptico, se determinó la frecuencia de adherencia a la guía para cada grupo de edades y se compararon las diferentes metas de reanimación en relación a la adherencia. Resultados: Excepto por la adherencia del inicio temprano de la antibiótico terapia, las demás metas presentaron una mejor adherencia, en el grupo de pacientes menores de 65 años cuando se compararon con los pacientes mayores de 65 años, la adherencia para ambos grupos disminuyo progresivamente a medida que se consideraron mayor número de metas. Conclusiones: Existe una menor adherencia a las guías de reanimación, en el grupo de grupo de pacientes mayores de 65 años con sepsis severa y choque séptico cuando se compara con el grupo de pacientes menores de 65 años.

Infecciones fúngicas emergentes: fungemia por Sporobolomyces salmonicolor. Reporte de un caso / Emerging fungal infections: Sporobolomyces salmonicolor fungemia. Case Report

En los últimos años, la emergencia de infecciones por hongos se ha dado en parte por el aumento en las infecciones por microrganismos que normalmente no son patógenos. El siguiente reporte describe la fungemia y meningoencefalitis por Sporobolomyces salmonicolor, una levadura frecuente en el medio ambiente y las plantas, en un paciente sin factores de riesgo conocidos, con desenlace fatal a pesar del manejo con antifúngicos. Este caso nos recuerda que dentro de las infecciones micóticas emergentes se encuentra el S. salmonicolor y se debe tener en cuenta dentro del diagnóstico diferencial de levaduras en sangre, como causa infrecuente, potencialmente mortal.

The emergence of pathogens, mainly fungi, in recent years has been partly due to overappearance of organisms that normally are not pathogenic in humans. The following report describes Sporobolomyces salmonicolor fungaemia and proven meningoencephalitis in a patient not showing risk factors who suffers a fatal outcome despite management with antifungal agents. The said yeast lives mainly in tree environments and plants. This case reminds us that there is S. salmonicolor within the emerging fungal infections, and this fact should be taken into account in the differential diagnosis of yeasts in blood as a rare and lifethreatening cause.
