RESUMO
Streptococcus agalactiae or Group B Streptococcus (GBS) infections are commonly associated with infections in neonates and pregnant women. However, there has been a rising incidence in nonpregnant adults. The risk of GBS infection in nonpregnant adults is increased for patients of advanced age and those with underlying medical conditions such as diabetes mellitus and cancer. We present a 77-year-old female with type-2 diabetes mellitus, hypertension, and bilateral foot ulcers that presented in probable septic shock with necrotic foot ulcers and necrotizing fasciitis and underwent bilateral lower limb amputations. The patient fulfilled the Streptococcal Toxic Shock Syndrome (STSS) criteria as defined by The Working Group on Severe Streptococcal Infections. These criteria were created for group A Streptococcus (Streptococcus pyogenes). Our patient fulfilled the Working Group's criteria, except that the blood culture was positive for group B Streptococcus (Streptococcus agalactiae). Numerous studies demonstrate the importance of early detection and antibiotic treatment for GBS infections in general and early surgical management for necrotizing soft tissue infections (NSTIs) such as necrotizing fasciitis.

RESUMO
INTRODUCCIÓN. La paradoja de la obesidad propone que, en determinadas enfermedades, los enfermos con obesidad tienen menor mortalidad. OBJETIVO. Asociar el índice de masa corporal con la mortalidad a 30 días en adultos con choque séptico. MATERIALES Y MÉTODOS. Estudio observacional, analítico, retrospectivo, multicéntrico. Se analizaron 673 pacientes con choque séptico, ingresados en terapia intensiva de dos hospitales de la ciudad de la ciudad de Quito Ecuador, durante enero 2017 - diciembre 2019. Criterios de inclusión: Mayores a 18 años, choque séptico, registro de peso, talla y condición vital al día 30. Criterios de exclusión: Orden de no reanimación, embarazadas, protocolo de donación de órganos, cuidados paliativos. Las variables se recolectaron a partir de las historias clínicas digitales y físicas de los centros participantes. Las estimaciones de riesgo calculadas se presentaron como OR (Odds Ratio) en el análisis bivariado y OR Adj (OR ajustado) para el análisis multivariado. Un valor de p <0.05 se consideró estadísticamente significativo. Todos los análisis estadísticos se realizaron usando el software estadístico R® (Versión 4.1.2). RESULTADOS. La edad promedio fue de 65 años, índice de masa corporal promedio 25,9 Kg/m2 (+4,9 Kg/m2). El 54,3% tuvo índice de masa corporal > 25 Kg/m2. La mortalidad general fue 49.2%. Sujetos con sobrepeso y obesidad tuvieron menor mortalidad, OR: 0,48 (IC 95%: 0.34, 0.68; p <0.0001) y OR 0.45 (IC 95 %: 0.28, 0.70; p =0.001) respectivamente, con similar tendencia en el análisis multivariado. Los sujetos con peso bajo tuvieron la mayor mortalidad (OR: 2.12. IC 95%: 0.91 - 5.54. p: 0.097). DISCUSIÓN. Los resultados obtenidos apoyan la teoría de paradoja de obesidad, sin embargo, no se realizó evaluación según los niveles de obesidad. CONCLUSIÓN. La mortalidad en choque séptico es menor en sujetos con sobrepeso y obesidad comparada con sujetos con peso normal o bajo peso.
The obesity paradox proposes that, in certain diseases, patients with obesity have lower mortality. OBJECTIVE. To associate body mass index with 30-day mortality in adults with septic shock. MATERIALS AND METHODS. Observational, analytical, retrospective, multicenter, retrospective study. We analyzed 673 patients with septic shock, admitted to intensive care in two hospitals in the city of Quito - Ecuador, during January 2017 - December 2019. Inclusion criteria: older than 18 years, septic shock, weight, height and vital condition at day 30. Exclusion criteria: Do not resuscitate order, pregnant women, organ donation protocol, palliative care. Variables were collected from the digital and physical medical records of the participating centers. Calculated risk estimates were presented as OR (Odds Ratio) in bivariate analysis and OR Adj (adjusted OR) for multivariate analysis. A p value <0.05 was considered statistically significant. All statistical analyses were performed using R® statistical software (Version 4.1.2). RESULTS. The mean age was 65 years, mean body mass index 25.9 kg/m2 (+4.9 kg/m2). Body mass index > 25 kg/m2 was 54.3%. Overall mortality was 49.2%. Overweight and obese subjects had lower mortality, OR: 0.48 (95% CI: 0.34, 0.68; p<0.0001) and OR 0.45 (95 % CI: 0.28, 0.70; p=0.001) respectively, with similar trend in multivariate analysis. Underweight subjects had the highest mortality (OR: 2.12. 95% CI: 0.91 - 5.54. p: 0.097). DISCUSSION. The results obtained support the obesity paradox theory, however, assessment according to obesity levels was not performed. CONCLUSIONS. Mortality in septic shock is lower in overweight and obese subjects compared to normal weight or underweight subjects.

El choque séptico es un estado de hipoperfusión tisular definido como subcategoría de la sepsis en la que las alteraciones circulatorias y del metabolismo celular pueden aumentar considerablemente la mortalidad. A nivel mundial, el choque séptico ocupa el segundo lugar como causa de muerte no coronaria en la Unidad de Cuidados Intensivos (UCI), con una incidencia anual del 10%, y con una mortalidad hospitalaria de 18 a 35%. Objetivo: Describir el abordaje del Proceso de Atención de Enfermería en el paciente con choque séptico y desde la perspectiva del déficit de autocuidado. Metodología: El caso clínico se fundamentó en las etapas del Proceso de Atención de Enfermería (PAE), en la Teoría Enfermera del Déficit de Autocuidado (TEDA) de Dorothea Orem y en herramientas taxonómicas para el abordaje individualizado del plan de cuidados. Resultados: Paciente de 68 años en el servicio de Cuidados Intensivos Adultos, cursa la primera hora del posoperatorio por nefrectomía izquierda secundaria a absceso perirenal, que condiciona a choque séptico. Se abordó el PAE con apoyo del TEDA siendo prioritaria la etiqueta diagnóstica disminución del gasto cardiaco. Conclusiones: La aplicación de las teorías y modelos de enfermería proporcionan un marco de referencia para otorgar cuidados de calidad en los diferentes ámbitos de desempeño, incluyendo unidades de atención de cuidados intensivos. Resulta indispensable usar la metodología del PAE que permite dar evidencia de la profesionalización del cuidado, al usar un lenguaje técnico, con el apoyo de la Teoría de Orem y con las herramientas taxonómicas[AU]
Septic shock is a state of tissue hypoperfusion defined as a subcategory of sepsis in which circulatory and cellular metabolism alterations can considerably increase mortality. Worldwide, septic shock ranks second as a cause of non-coronary death in the Intensive Care Unit (ICU), with an annual incidence of 10%, and a hospital mortality of 18 to 35%. Objective: To describe the approach to the Nursing Care Process in patients with septic shock and from the perspective of self-care deficit. Methodology: The clinical case was based on the stages of the Nursing Care Process (PAE), on the Nursing Theory of Self-Care Deficit (TEDA) by Dorothea Orem and on taxonomic tools for the individualized approach to the care plan. Results: A 68-year-old patient, in the Adult Intensive Care service, undergoes the first postoperative hour due to left nephrectomy secondary to perirenal abscess, which conditions septic shock. The PAE was approached with the support of the TEDA, with a priority being the dignostic label reduction of cardiac output. Conclusions: The application of nursing theories and models provide a frame of reference to provide quality care in different areas of performance, including intensive care units. It is essential to use the PAE methodology that allows to give evidence of the professionalization of care, by using technical language, with the support of Orem's Theory and with taxonomic tools[AU]

RESUMO
Sepsis is one of the leading causes of death in critically ill patients with COVID-19 and blood purification therapies have a role to immunomodulate the excessive inflammatory response and improve clinical results. One of the devices designed for these therapies is the oXiris® filter, allowing to perform renal replacement therapy combined with selective adsorption of endotoxins and cytokines. We report a 55-year-old male with COVID who developed a septic shock secondary to a sepsis caused by Pseudomona aeruginosa, refractory to the usual management. A veno-venous continuous hemofiltration was started using the oXiris® filter for 48 hours. Subsequently, there was an improvement in clinical perfusion parameters and a reduction in inflammatory markers. The patient was discharged from the intensive care one month later.

ABSTRACT Objective: To analyze the incidence, complications, and hospital discharge status in newborns with ≥35 weeks of gestational age with early neonatal sepsis. Methods: This is a cross-sectional, retrospective study. Cases of early-onset sepsis registered from January 2016 to December 2019 in neonates with gestational age of 35 weeks or more were reviewed in a level III neonatal unit. The diagnoses were performed based on the criteria by the Brazilian Health Regulatory Agency (Anvisa), and the episodes were classified according to microbiological classification and site of infection. The following complications were evaluated: shock, coagulation disorders, and sequelae of the central nervous system. The conditions at hospital discharge were also assessed. The collected data were analyzed with the descriptive analysis. Results: In the period, early neonatal sepsis occurred in 46 newborns, corresponding to 1.8% of all newborns admitted to the neonatal unit, with a prevalence of 4/1,000 live births. Culture confirmed sepsis ocurred in three patients (0.3/1,000 live births), with the following agents: S. pneumoniae, S. epidermidis and S. agalactiae. As to site of infection, there were 35 cases of primary bloodstream infection, seven cases of pneumonia and four cases of meningitis. Most patients (78.3%) had at least one risk factor for sepsis, and all were symptomatic at admission. There were no deaths. Complications occurred in 28.2% of the cases, especially shock (10 cases - 21.7%). Conclusions: The prevalence of proven early neonatal sepsis was low. Despite the common occurrence of complications, there were no deaths.
RESUMO Objetivo: Analisar a prevalência, as complicações e as condições de alta dos recém-nascidos ≥35 semanas com diagnóstico de sepse neonatal precoce. Métodos: Estudo transversal, com coleta retrospectiva de dados. Incluíram-se todos recém-nascidos com 35 semanas ou mais de idade gestacional, com diagnóstico de sepse precoce em um período de quatro anos (janeiro/2016 a dezembro/2019) em uma unidade neonatal nível III. Os diagnósticos realizaram-se segundo os critérios da Agência Nacional de Vigilância Sanitária e os episódios classificados segundo a confirmação microbiológica e o sítio de infecção. As complicações avaliadas foram: choque, distúrbio de coagulação e sequelas do sistema nervoso central. Também se avaliaram as condições de alta. Os dados coletados foram analisados utilizando estatística descritiva. Resultados: No período, 46 recém-nascidos apresentaram sepse precoce, correspondendo a 1,8% das internações e a uma prevalência de 4/1.000 nascidos vivos. Em três pacientes a sepse foi confirmada por culturas (0,3/1.000 nascidos vivos), respectivamente por S. pneumoniae, S. epidermidis e S. agalactiae. Quanto ao sítio de infecção, foram 35 casos de infecção primária da corrente sanguínea, 7 casos de pneumonia e 4 de meningite. A maior parte dos pacientes (78,3%) possuía pelo menos um fator de risco para sepse, e todos apresentaram-se sintomáticos. Não houve óbito. Complicações ocorreram em 28,2% dos casos, especialmente choque (10 casos - 21,7%). Conclusões: A prevalência de sepse neonatal precoce comprovada foi baixa. Apesar da ocorrência comum de complicações, não houve óbitos.
RESUMO
ABSTRACT Objective To describe the clinical characteristics and treatment of children with sepsis, severe sepsis, and septic shock at a pediatric emergency department of a public hospital. Methods A retrospective, observational study. The medical records of patients included in the hospital Pediatric Sepsis Protocol and patients with discharge ICD-10 A41.9 (sepsis, unspecified), R57 (shock) and A39 (meningococcal meningitis) were evaluated. Results A total of 399 patients were included. The prevalence of sepsis, severe sepsis, and septic shock at the emergency room were 0.41%, 0.14% and 0.014%, respectively. The median age was 21.5 months for sepsis, 12 months for severe sepsis, and 20.5 months for septic shock. Sepsis, severe sepsis, and septic shock were more often associated with respiratory diseases. The Respiratory Syncytial Virus was the most common agent. The median time to antibiotic and fluid administration was 3 hours in patients with sepsis and severe sepsis. In patients with septic shock, the median times to administer antibiotics, fluid and vasoactive drugs were 2 hours, 2.5 hours and 6 hours, respectively. The median length of hospital stay for patients with sepsis, severe sepsis and septic shock were 3 days, 4 days and 1 day, respectively. The overall mortality was 2%. Conclusion Sepsis had a low prevalence. Early diagnosis and recognition are a challenge for the emergency care pediatrician, the first place of admission.
