ABSTRACT
Sepsis-induced thrombocytopenia-associated multiple organ failure(TAMOF)is a severe subtype of sepsis-related organ dysfunctions,which has high mortality and poor prognosis.The main clinical characteristics are thrombocytopenia caused by infection and multiple organ dysfunction.However,the exact molecular mechanism of TAMOF remains unclear.The current studies have shown ADAMTS-13,which is a von Willebrand factor lyase,plays an important role during the disease.Plasma exchange could be a treatment method,but still need more large-scale randomized controlled trials to verify.In the future,von Willebrand factor and ADAMTS-13 could become the therapeutic targets for new drug development.
ABSTRACT
Objective To investigate changes in coagulation function and inflammation levels during sepsis.Methods A rat model of sepsis was established using the multiple infection sepsis model(MIM)based on cecal ligation and puncture.Forty-eight male Sprague-Dawley rats were assigned randomly to the following groups:control group,sham group,4 h sepsis group,8 h sepsis group,12 h sepsis group,and 16 h sepsis group(n=8 per group).Inflammatory markers and coagulation-related indicators were measured by enzyme-linked immunosorbent assay and coagulation analysis.Results(1)Lipopolysaccharide(LPS)and interleukin-6(IL-6)levels were significantly higher in the model rats at all time points compared with the sham group(P<0.001).LPS and IL-6 levels increased gradually with disease progression,with no further changes in LPS after 12 hours.(2)Prothrombin time(PT)was significantly prolonged in the middle and late stages of the sepsis model,starting from 8,compared with the sham group(P<0.01).(3)Partially activated prothrombin time(APTT)time was significantly prolonged in the 8,12,and 16 h groups compared with the sham group(P<0.05,P<0.01).APTT gradually lengthened from 8 h,but approached control levels thereafter.(4)Fibrinogen(Fbg)content was significantly higher in all sepsis groups,except for the 8 h group,compared with the sham group(P<0.01).(5)Fibrin degradation products(FDP)differed significantly between the control and sham groups(P<0.01),but not between the sham and sepsis groups.(6)Antithrombin-Ⅲ(AT-Ⅲ)levels decreased significantly throughout each stage of sepsis progression compared with the sham group(P<0.01),and AT-Ⅲ showed a downward trend with the course of disease,with significant differences among the 4,8,and 16 h groups.Conclusions The MIM rat model can reflect the development of inflammatory and blood coagulation disorders and their relationship during the course of sepsis,and may thus provide a good foundation for further research into the disease course of sepsis.
ABSTRACT
La isquemia intestinal aguda es una emergencia vascular provocada por fenómenos oclusivos y no oclusivos de la circulación mesentérica arterial y venosa, de difícil diagnóstico y pronóstico ominoso. Su incidencia va en aumento paulatino con el decurso de los años, asociada fundamentalmente al envejecimiento de la población. La tasa de mortalidad es elevada a pesar de los avances en el campo de la imagenología. Suele diagnosticarse de forma tardía, cuando está establecido el daño isquémico intestinal de carácter irreversible. El elemento imprescindible e indispensable lo constituye el tiempo que trascurre hasta la cirugía, por lo que su diagnóstico sigue siendo un reto clínico. El tratamiento exige medidas médicas intensivas, al igual que cirugía de revascularización y resección del intestino necrosado. Por desdicha, el examen físico y los hallazgos de laboratorio no son sensibles ni específicos para su diagnóstico. Teniendo en cuenta estos elementos, se presenta el caso de una paciente de 38 años con clínica difusa de vómitos, diarrea y dolor abdominal progresivo, que requirió intervención quirúrgica de urgencia con diagnóstico transoperatorio de isquemia mesentérica aguda. Durante su estancia hospitalaria se relaparotomizó en dos ocasiones, mantuvo soporte ventilatorio e inotrópico por fallo multiorgánico en la Unidad de Cuidados Intensivos, mostrando una adecuada evolución posquirúrgica. El objetivo de esta presentación es enfatizar en la clínica como elemento fundamental para abordar de forma correcta esta entidad en un medio hospitalario de limitados recursos diagnósticos imagenológicos, al abordar conceptos teóricos recientes y facilitar una adecuada actuación en la toma de decisiones.
Acute intestinal ischemia is a vascular emergency caused by occlusive and non-occlusive phenomena of the mesenteric arterial and venous circulation of difficult diagnosis and ominous prognosis. Its incidence is gradually increasing over the years, mainly associated with the ageing of the population. The mortality rate is high despite advances in the field of imaging. It is usually diagnosed late, when irreversible ischemic intestinal damage is established. The essential and indispensable element is the time that elapses until surgery, so its diagnosis continues to be a clinical challenge. Treatment requires intensive medical measures, as well as revascularization surgery and resection of the necrotic intestine. Unfortunately, physical examination and laboratory findings are neither sensitive nor specific for its diagnosis. Taking these elements into account, the authors present the case of a 38-year-old female patient with diffuse symptoms of vomiting, diarrhea and progressive abdominal pain that required emergency surgery with intraoperative diagnosis of acute mesenteric ischemia. During her hospital stay, she underwent re-laparotomy twice, maintained ventilatory and inotropic support due to multi-organ failure in the Intensive Care Unit, showing an adequate post-surgical evolution. The objective of this presentation is to emphasize in the clinic as a fundamental element to correctly address this entity in a hospital environment with limited imaging diagnostic resources by addressing recent theoretical concepts and facilitating adequate action in decision-making.
ABSTRACT
ABSTRACT CONTEXT: Scrub typhus, caused by Orientia tsutsugamushi, has a wide range of clinical manifestations, including meningoencephalitis, acute renal failure, pneumonitis, myocarditis, and septic shock. However, there are no documented cases of scrub typhus with hypokalemia. In this report, we present a case of scrub typhus with hypokalemia and multiple organ failure syndrome, highlighting the importance of electrolyte imbalance in patients with scrub typhus. CASE REPORT: A 59-year-old woman presented to the emergency department with abdominal pain that had been present for 1 day. On admission, the physical examination and laboratory test results indicated that the patient had renal, liver, and circulatory failure, and hypokalemia. She developed meningitis and disseminated intravascular coagulation during hospitalization. She recovered with appropriate management, and was discharged on day 17. CONCLUSION: This report highlights the potential for atypical presentations of scrub typhus, including a previously undocumented association with hypokalemia. Although the contribution of hypokalemia to the patient's clinical course remains uncertain, this case underscores the importance of considering electrolyte imbalance in the management of patients with scrub typhus. Further research is warranted to better understand the relationship between scrub typhus and electrolyte imbalance.
ABSTRACT
Resumo Objetivo Mapear as evidências disponíveis sobre as ações do óxido nítrico na fisiopatologia da sepse e sua relação com a gravidade de pacientes sépticos. Método Revisão de escopo de acordo com a metodologia do Joanna Briggs Institute. Realizou-se busca por estudos que evidenciaram as ações do óxido nítrico na sepse e se o seu aumento está associado à gravidade de pacientes sépticos. Dois revisores independentes fizeram o mapeamento das informações utilizando um instrumento de extração de dados previamente elaborado. Os dados foram analisados quanto à sua relevância, sendo posteriormente extraídos e sintetizados. Resultados De 1342 estudos, 11 foram incluídos na revisão. O primeiro foi publicado em 2017 e o último, em 2022. A maioria foi desenvolvida nos Estados Unidos, na China e na Alemanha. Os estudos apresentaram informações referentes as ações do óxido nítrico, sintetizando sua biodisponibilidade e os inibidores endógenos relacionados a sua produção, além de abordarem a relação do óxido nítrico com a gravidade da sepse. Conclusão A produção de óxido nítrico fisiológico durante a sepse atua como protetor vascular, principalmente na microcirculação, porém, em altas concentrações, contribui para a disfunção vascular, que subverte a fisiologia da regulação da pressão arterial, causando profunda vasodilatação e hipotensão refratária e aumentando a gravidade de pacientes sépticos.

Abstract Objective Map the available evidence on the actions of nitric oxide in the pathophysiology of sepsis and its relationship with the severity of sepsis in patients. Method Scoping review following the Joanna Briggs Institute methodology. A search was carried out for studies that highlighted the actions of nitric oxide in sepsis, informing whether its increase is associated with the severity of sepsis in patients. Two independent reviewers mapped the information using a previously designed data extraction instrument. The data was analyzed for its relevance and then extracted and synthesized. Results Eleven of 1342 studies were included in the review. The first of them was published in 2017 and the last in 2022. Most of them were developed in the USA, China, and Germany. Studies have reported the actions and bioavailability of nitric oxide and endogenous inhibitors related to its production, and related nitric oxide to the severity of sepsis. Conclusion The physiological production of nitric oxide during sepsis acts as a vascular protector, mainly in the microcirculation but contributes to vascular dysfunction in high concentrations, subverting the regulation of blood pressure, causing deep vasodilation and refractory hypotension, and increasing the severity of sepsis in patients.

ABSTRACT
Background: The novel coronavirus had a severe impact on India, with cases ranging from mild disease to severe multiple-organ failure syndrome. Caregivers of high-risk individuals face additional responsibilities that have detrimental effects on their mental and physical health. This study aimed to assess the quality of life of family caregivers, the impact on health expenditure, and the role of home-based medical devices during the pandemic in India. Methods: This retrospective study collected data from 358 participants using a validated caregiver self-assessment questionnaire and demographic details. The data were processed using the statistical tool chi-square, with p-value <0.05 considered significant, and analyzed using SPSS 11. The data is depicted using pie charts and bar diagrams. Results: 93.02% of our participants assumed a caregiver role. Among these, 58.26% reported mental distress. 7.21% of caregivers reported using telemedicine facilities, and 32% reported an increase in health-related expenditure in an attempt to provide better medical care to their loved one. More than 80% of the participants reported having a family member suffering from diabetes, while 70% reported old age or hypertension. Less than 10% had a loved one who was a pregnant woman or a frontline worker. Conclusions: The study highlights the significant impact of the COVID-19 pandemic on the mental health of family caregivers of chronically ill patients in India. The use of telemedicine facilities and the increase in health-related expenditure reflect the need for advancement in healthcare infrastructure in India.
ABSTRACT
Background: Septic complications in traumatic brain injury causes short- and long-term cerebral dysregulation by disruption of blood brain barrier, reduced brain perfusion, neuroinflammation and deposition of amyloid. Materials and methods: The present study attempted to observe patients of traumatic brain injury for the development of septic complications during the hospital stay. 89 patients were included in the study with different grades of brain injury (Injury Severity Score (ISS) range, 9-72). The patients were managed according to the trauma protocol and classified into 3 groups based on the severity of trauma (ISS 9-17 (moderate), 18-30 (severe), and >32 (most severe)). The patients were observed for the development of major septic complications during the course of their hospital stay, which impacted on the morbidity and mortality while determining the clinical and functional outcome at the end. Results: Mean age of the study population was 33.5 years. TBI was more common in younger age groups with severe grades of injury, those with multiplicity of head injuries, sepsis with a pulmonary focus, prolonged ICU and in-hospital stay together with high mortality. Septic complications were also more common in cases with higher grades of TBI and more prolonged hospital stay. Patients requiring intubation had a higher risk of developing infectious complications. 69 patients (77.5%) required intubation and mechanical ventilation. Pneumonia was the most common source of sepsis leading to the respiratory failure while the most common cause being aspiration at the time of injury Genitourinary complications were also common leading to urosepsis. Most common organisms isolated were Staphylococcus aureus, Acinetobacter, klebsiella and Pseudomonas. Conclusion: Traumatic brain injury (TBI) when complicated by sepsis and multi organ failure increases the mortality and morbidity with less favorable clinical and functional outcome together with increased duration of ICU and hospital stay.
ABSTRACT
The coronavirus disease 2019 (COVID-19) has been a global epidemic for more than three years, causing more than 6.9 million deaths. COVID-19 has the clinical characteristics of strong infectivity and long incubation period, and can cause multi-system damage, mainly lung damage, clinical symptoms of acute respiratory distress syndrome (ARDS) and systemic multiple organ damage. The SARS-CoV-2 virus is still constantly mutating. At present, there is no global consensus on the pathological changes of COVID-19 associated deaths and even no consensus on the criteria for determining the cause of death. The investigation of the basic pathological changes and progression of the disease is helpful to guide the clinical treatment and the development of therapeutic drugs. This paper reviews the autopsy reports and related literature published worldwide from February 2020 to June 2023, with a clear number of autopsy cases and corresponding pathological changes of vital organs as the inclusion criteria. A total of 1 111 autopsy cases from 65 papers in 18 countries are included. Pathological manifestations and causes of death are classified and statistically analyzed, common pathological changes of COVID-19 are summarized, and analytical conclusions are drawn, suggesting that COVID-19 infection can cause life-threatening pathological changes in vital organs. On the basis of different health levels of infected groups, the direct cause of death is mainly severe lung damage and secondary systemic multiple organ failure.

Objective:To investigate the relationship between serum interleukin-6 and interleukin-10 levels and clinical prognosis in patients with severe acute pancreatitis.Methods:Ninety-two patients with severe acute pancreatitis who received treatment in The Second People's Hospital of Liaocheng from August 2018 to July 2021 were included in this study. Serum interleukin (IL)-6 and IL-10 levels were detected. The Bedside Index of Severity in Acute Pancreatitis (BISAP) score was evaluated. Clinical interventions were performed. The relationship between serum IL-6 and IL-10 levels and the clinical prognosis of severe acute pancreatitis was investigated.Results:Serum IL-6 level [(103.75 ± 15.53) ng/L] was highest in patients who died. Serum IL-10 level [(97.33 ± 13.06) ng/L] was highest in patients with local complications. The highest number of patients with a prognostic outcome of death [26 (37.14%)] was found in patients with a BISAP score ≥ 3. Serum IL-6 level in patients with severe acute pancreatitis was positively correlated with the BISAP score ( r = 0.62, P < 0.05), and serum IL-6 level and BISAP score were negatively correlated with serum IL-10 level ( r = -0.57, -0.61, both P < 0.05). Conclusion:Increased or decreased serum IL-6 and IL-10 levels in patients with severe acute pancreatitis indicate that the patient's condition tends to worsen, and timely intervention according to serum IL-6 and IL-10 levels can improve the clinical prognosis of severe acute pancreatitis.
ABSTRACT
Wasp sting is a common emergency in mountainous areas of China, with rapid onset and progression, high mortality rate, and serious harm to public health. Wasp sting can cause mild local reactions in mild cases, and Anaphylaxis or even multiple organ dysfunction in severe cases, of which Acute kidney injury (AKI) is the most common and serious. Blood purification treatment is commonly used for wasp sting patients to maintain renal function, eliminate toxins, and maintain Internal environment stability. The commonly used clinical methods are Hemoperfusion (HP), plasma exchange (PE), and continuous renal replacement therapy (CRRT). At present, there is no clear recommendation for the blood purification treatment mode of wasp sting in China, and there is no clear guidance for its combined treatment mode. This article will review the single and combined use of blood purification treatment models for wasp stings, based on the latest clinical research.
ABSTRACT
Extracorporeal membrane oxygenation (ECMO) is a technique in which breathing and circulation are supported extracorporeally. Severe trauma may induce cardiopulmonary failure, for which ECMO can play an adjunctive role in the salvage treatment of circulatory and respiratory failure when conventional treatments are ineffective. Bypass with ECMO can rapidly improve the state such as circulatory failure and hypoxemia in critically ill patients in short term and can partially or fully replace their cardiopulmonary function in long term, winning valuable time for normal recovery of cardiopulmonary function. Because of the physical state of severe trauma patients and the ECMO equipment, there are still various complications clinically. Trauma patients show high risk of bleeding, vulnerability to wound infection and probability of combined organ injury and dysfunction, so more comprehensive measures for the prevention and treatment of complications during the use of ECMO therapy are required. The authors review the research progress in complications and corresponding prevention and treatment strategies during ECMO support for severe trauma, aiming to provide a reference to prevent and treat these complications.
ABSTRACT
Acute-on-chronic liver failure (ACLF) refers to acute liver function decompensation on the basis of chronic liver diseases and is a complex clinical syndrome characterized by organ failure and high short-term mortality. ACLF is reversible and has diverse long-term outcomes and prognoses. The clinical classification of ACLF based on disease characteristics is of great significance for optimizing the management pathways for ACLF. With reference to the definition and clinical features of ACLF in the East and the West, this article redefines ACLF from the new perspective of onset manifestations and dynamic outcomes and proposes a new clinical classification of ACLF. The first classification of ACLF is based on the clinical features of intrahepatic and extrahepatic organ failure at disease onset, i.e., type Ⅰ ACLF (liver failure on the basis of chronic liver diseases) and type Ⅱ ACLF (acute decompensation on the basis of chronic liver diseases comorbid with multiple organ failure). The second classification is the dynamic clinical classification of ACLF based on clinical outcome, i.e., type A (rapid progression), type B (rapid recovery), type C (slow progression), type D (slow recovery), and type E (slow persistence). The proposed clinical classification of ACLF from the new perspective expects Eastern and Western scholars to have a more inclusive understanding of ACLF, narrow differences, optimize disease management paths, and rationally use medical resources, thereby providing a reference for clinicians.
ABSTRACT
Abstract Objective: This study aimed to describe the clinical characteristics and the different phenotypes of children with multisystem inflammatory syndrome in children (MIS-C) temporally related to COVID-19 and to evaluate the risk conditions that favored a greater severity of the disease during a 12-month period at a pediatric reference hospital in Colombia. Methods: A 12-month retrospective observational study of children under the age of 18 years who met criteria for MIS-C. Results: A total of 28 children presented MIS-C criteria. The median age was 7 years. Other than fever (100%) (onset 4 days prior to admission), the most frequent clinical features were gastrointestinal (86%) and mucocutaneous (61%). Notably, 14 (50%) children had Kawasaki-like symptoms. The most frequent echocardiographic abnormalities were pericardial effusion (64%), valvular involvement (68%), ventricular dysfunction (39%), and coronary artery abnormalities (29%). In addition, 75% had lymphopenia. All had at least one abnormal coagulation test. Most received intravenous immunoglobulin (89%), glucocorticoids (82%), vasopressors (54%), and antibiotics (64%). Notably, 61% had a more severe form of the disease and were admitted to an intensive care unit (median 4 days, mean 6 days); the severity predictors were patients with the inflammatory/MIS-C phenotype (OR 26.5; 95%CI 1.40-503.7; p=0.029) and rash (OR 14.7; 95%CI 1.2-178.7; p=0.034). Two patients had macrophage activation syndrome. Conclusions: Coronary artery abnormalities, ventricular dysfunction, and intensive care unit admission were frequent, which needs to highlight the importance of early clinical suspicion.
Resumo Objetivo: Descrever as características clínicas e os diferentes fenótipos de crianças com síndrome inflamatória multissistêmica na criança temporalmente relacionada com a COVID-19 (do inglês multisystem inflammatory syndrome in children — MIS-C) e avaliar as condições de risco que favorecem a maior gravidade da doença durante um período de 12 meses em um hospital pediátrico de referência na Colômbia. Métodos: Estudo retrospectivo de 12 meses de observação de crianças menores de 18 anos que cumprem os critérios para o MIS-C. Resultados: Vinte e oito crianças foram apresentadas com os critérios do MIS-C. A idade média era de sete anos, e 54% eram do sexo masculino. Para além da febre (100%) (com início quatro dias antes da admissão), as características clínicas mais frequentes eram gastrointestinais (86%) e mucocutâneas (61%). Quatorze crianças (50%) apresentavam sintomas semelhantes aos de Kawasaki. As anomalias ecocardiográficas mais frequentes foram derrame pericárdico (64%), envolvimento valvar (68%), disfunção ventricular (39%) e anomalias coronárias (29%). Tinham linfopenia 75% das crianças. Todas tinham algum teste de coagulação anormal. A maioria recebeu imunoglobulina intravenosa (89%), glucocorticoides (82%), vasopressores (54%) e antibióticos (64%). Tiveram envolvimento mais grave 61% dos pacientes, que precisaram ser internados em unidade de terapia intensiva (mediana de quatro dias, média de seis dias); os preditores de gravidade foram pacientes com fenótipo inflamatório/ MIS-C (odds ratio — OR 26,5; intervalo de confiança — IC95% 1,4-503,7; p=0,029) e erupção cutânea (OR 14,7; IC95% 1,2-178,7; p=0,034). Dois pacientes (7%) apresentavam síndrome de ativação macrofágica. Conclusões: Alteração da artéria coronária, disfunção ventricular e internação na unidade de terapia intensiva foram frequentes, o que nos alerta sobre a importância da suspeita clínica precoce.

Materiales y método: Serie de casos. Se incluyeron sujetos mayores de 18 años que requirieron una CCV a través de esternotomía, entre julio de 2017 y noviembre de 2018. Se excluyeron sujetos con datos faltantes y se eliminaron quienes fallecieron durante la cirugía. Se llevó a cabo un análisis de regresión logística para determinar las variables predictoras de la ocurrencia de VMP. Resultados: De 70 sujetos analizados, 17,1% requirió VMP, cuya mortalidad fue de 41,7%. En el análisis univariado la obesidad, días de internación, tiempo de cirugía, necesidad de circulación extracorpórea (CEC), desarrollo de complicaciones posoperatorias (POP) y puntaje del score Sequential Organ Failure Assessment (SOFA) en el posquirúrgico inmediato, se asociaron significativamente a VMP. Conclusión: La proporción de sujetos con requerimiento de VMP fue superior a lo reportado en la literatura. El tiempo de cirugía, el SOFA en el POP inmediato, obesidad, necesidad de CEC, días de internación y desarrollo de complicaciones POP se asociaron con VMP.
ABSTRACT Objective: To describe the demographic characteristics and proportion of postoperative cardiovascular subjects who require prolonged mechanical ventilation (PMV) and to analyze associated factors. Materials and method: A case series study was conducted on subjects over 18 years of age who required cardiac surgery via median sternotomy between July 2017 and November 2018. Subjects with missing data were excluded, and subjects who died during surgery were eliminated. A logistic regression analysis was performed to identify predicting factors associated with PMV. Results: Of the 70 subjects analyzed, 17.1% required PMV, with a mortality of 41.7%. In the univariate analysis, obesity, length of hospital stay, duration of surgery, need of extracorporeal circulation, postoperative complications, and sequential organ failure assessment (SOFA) scores in the immediate postoperative period were significantly associated with PMV. Conclusion: The proportion of subjects requiring PMV was higher than the reported in the literature. The duration of surgery, obesity, need of extracorporeal circulation, length of hospital stay, postoperative complications, and SOFA scores in the immediate postoperative period were associated with PMV.
ABSTRACT
Objective:To investigate the effects of sequential organ failure assessment (SOFA) score, Braden Scale score, and nutritional indicators in patients with pressure ulcer after spinal cord injury.Methods:Eighty spinal cord injury patients with pressure ulcer who received treatment in the First People's Hospital of Huzhou, China between January 2019 and February 2020 were included in the patient group. Among these patients, 22 had stage I pressure ulcer, 33 had stage II pressure ulcer, and 25 had stage III pressure ulcer. An additional 140 patients with spinal cord injury but without pressure ulcer who concurrently received treatment in the same hospital were included in the control group. SOFA score, Braden Scale score and nutritional indicators were compared between the two groups. The correlation between SOFA score, Braden scale score and nutritional indicators was analyzed.Results:There were no significant differences in gender, age, hypertension, diabetes, operation condition and American Spinal Injury Association Impairment Scale score between the two groups (all P > 0.05). There were significant differences in body mass index [(24.25 + 1.44) kg/m 2vs. (27.68 + 2.21) kg/m 2, t = 12.44, P < 0.05], use of vasoactive drugs (29.29% vs. 43.75%, χ 2 = 4.71, P < 0.05), length of hospital stay [(10.71 + 2.62) days vs. (16.39 + 3.05) days, t = 14.56, P < 0.05]. SOFA score in the observation group was significantly higher than that in the control group [(9.72 ± 1.18) points vs. (4.51 ± 0.30) points, t = 49.58, P < 0.001]. Braden scale score in the observation group was significantly lower than that in the control group [(10.64 ± 1.05) points vs. (13.49 ± 2.28) points, t = 10.55, P < 0.001]. Serum level of hemoglobin, prealbumin, and albumin in the observation group was (81.03 ± 8.48) g/L, (145.29 ± 14.72) mg/L, (20.24 ± 2.05) g/L, respectively, which were significantly lower than those in the control group [(107.25 ± 10.14) g/L, (170.86 ± 23.75) mg/L, (32.38 ± 4.07) g/L, t = 19.54, 8.71, 24.91, all P < 0.001]. Spearman correlation analysis showed that SOFA score was positively correlated with serum level of hemoglobin, prealbumin, and albumin ( r = 0.50, 0.64, 0.71, all P < 0.05). SOFA score was negatively correlated with Braden Scale score ( r = -0.51, -0.62, -0.75, all P < 0.05). Conclusion:Pressure ulcer in spinal cord injury is caused by combined action of multiple factors. SOFA score, Braden scale score, and combined detection of hemoglobin, prealbumin, and albumin can be used to better evaluate pressure ulcer after spinal cord injury.
ABSTRACT
Acute-on-chronic liver failure (ACLF) is a disease of rapid deterioration of liver function caused by the acute exacerbation of chronic liver diseases, and it is often associated with multiple organ failure and has a poorer prognosis than common liver cirrhosis. Many studies suggest that timely liver transplantation can significantly improve the survival rate of patients with ACLF; however, there are currently no reliable guidelines that point out the indications for liver transplantation in patients with ACLF. This article summarizes recent studies and discusses the indication, timing, and prognosis of liver transplantation in ALCF patients.
ABSTRACT
Objective:To analyze the effects of infectious complications [infected pancreatic necrosis (IPN) and extra-pancreatic infection (EPI)] on the outcomes of patients with severe acute pancreatitis (SAP), and evaluate the differences in infection time, infection site and infecting species between SAP patients with infections complications.Methods:The clinical data of 66 SAP patients with combined infectious complications admitted to Xuanwu Hospital, Capital Medical University from January 2014 to December 2020 were retrospectively analyzed, and SAP patients were divided into IPN group ( n=7), EPI group ( n=14) and co-infection (EPI+ IPN) group ( n=45) according to the type of infection. Whether the study data conformed to a normal distribution was assessed by the Shapiro-Wilk test, normally distributed measures were expressed as mean ± standard deviation ( ± s), and ANOVA was used for comparison between groups; skewed measures were expressed as median (interquartile range) [ M ( Q1, Q3)], and the rank-sum test was used for comparison between groups. Bonferroni correction was used for multiple group comparisons ( P value significance level reduced to 0.017). Quantitative data were compared between groups using the χ2 test or Fisher's exact probability method. Results:There were no statistical differences between the three groups in terms of baseline data at admission (gender, age, etiology, modified CTSI score, degree of pancreatic necrosis, and number of organ failure) ( P>0.05), patients in the EPI group were referred earlier than the other two groups ( P<0.05). In clinical treatment, patients in the IPN group and co-infection group required multiple minimally invasive interventions compared with those in the EPI group ( P<0.05), and the number of patients requiring combined nutritional support, length of intensive care unit stay, and total length of hospital stay were higher in the co-infection group than in the other two groups ( P<0.05). In addition, 360 strains of pathogenic bacteria were cultured in this study, with Gram-negative bacteria being the most common, and patients with SAP were more likely to have EPI in the early stage of disease onset, with bacteremia and respiratory tract infections in the early stage (≤14 d), and bacteremia, urinary tract infections, and catheter-associated infections in the late stage (>14 d). Conclusions:Among patients with SAP, patients in the co-infection group had higher surgical intervention, nutritional support and length of hospital stay than those in the single infection group. It is advisable to prioritize EPI in SAP patients with suspected infections, and the common infectious strains in SAP patients are still predominantly Gram-negative bacteria, and clinicians need to adjust the treatment plan in a timely manner according to the changes in patients′ conditions.
ABSTRACT
Objective:To investigate the effect of insulin secretion index (HOMA-β) in the evaluation of the condition of patients with acute respiratory distress syndrome (ARDS), multiple organ failure (MOF) and prognosis prediction.Methods:A retrospective analysis of the clinical data of 96 patients with ARDS hospitalized in Hangzhou Hospital of Zhejiang Medical Health Group from January 2019 to February 2021 was divided into MOF group (38 cases) and non-MOF group (58 cases). The baseline HOMA-β, oxygenation index, acute physiology and chronic health score Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA) and 28 d case fatality rate were collected and compared between the two groups. Compare the HOMA-β, oxygenation index, APACHE Ⅱ score, SOFA of ARDS patients with different survival prognosis. Logistic regression model analyzed the influence of HOMA-β, oxygenation index, APACHE Ⅱ, SOFA on the MOF and survival prognosis of ARDS patients. Pearson linear correlation method was used to analyze the relationship between HOMA-β and oxygenation index, APACHE Ⅱ, SOFA in ARDS patients. Receiver operating characteristic (ROC) curve was used to analyze the predictive power of HOMA-β on MOF and prognosis of ARDS patients.Results:The incidence of MOF and 28 d case fatality rate in 96 patients with ARDS were 39.58% (38/96) and 31.25% (31/96), respectively. The HOMA-β and oxygenation index in the MOF group were significantly lower than those in non-MOF group: 126.37 ± 28.75 vs. 178.52 ± 32.66, (125.41 ± 18.77) mmHg (1 mmHg = 0.133 kPa) vs. (153.62 ± 26.42) mmHg, while the APACHE Ⅱ, SOFA and 28 d case fatality rate were significantly higher than those in non-MOF group: (23.61 ± 4.68) points vs. (10.96 ± 2.85) points, (11.24 ± 1.65) points vs. (5.62 ± 0.87) points and 65.79% (25/38) vs. 10.34% (6/58), and there were statistical differences ( P<0.05). The HOMA-β and oxygenation index in dead ARDS patients were significantly lower than those in surviving ARDS patients: 89.62 ± 21.17 vs. 195.43 ± 35.64 and (121.66 ± 21.06) mmHg vs. (158.87 ± 28.71) mmHg, the APACHE Ⅱ and SOFA were significantly higher than those in surviving ARDS patients: (25.78 ± 5.42) points vs. (8.84 ± 2.51) points, (12.38 ± 1.22) points vs. (4.88 ± 0.83) points, and there were statistical differences ( P<0.05). Logistic regression model analysis showed that HOMA-β, oxygenation index, APACHE Ⅱ, SOFA of ARDS patients were all influencing factors of MOF and survival prognosis ( P<0.05). The results of Pearson linear correlation analysis showed that HOMA-β in ARDS patients was positively correlated with its oxygenation index ( P<0.05), and its APACHE Ⅱ and SOFA were negatively correlated ( P<0.05). ROC curve analysis results show that HOMA-β in ARDS patients has a high predictive power for their MOF and prognosis. Conclusions:The level of HOMA-β in ARDS patients is low, and it is closely related to its condition, MOF occurrence and survival prognosis. It can be used as a reference index for disease assessment and MOF and prognosis prediction of ARDS patients.
ABSTRACT
ABSTRACT Objective: To evaluate clinical outcomes and factors associated with mortality, focusing on secondary infections, in critically ill patients with COVID-19 in three Brazilian hospitals during the first pandemic wave. Methods: This was a retrospective observational study involving adult patients with COVID-19 admitted to one of the participating ICUs between March and August of 2020. We analyzed clinical features, comorbidities, source of SARS-CoV-2 infection, laboratory data, microbiology data, complications, and causes of death. We assessed factors associated with in-hospital mortality using logistic regression models. Results: We included 645 patients with a mean age of 61.4 years. Of those, 387 (60.0%) were male, 12.9% (83/643) had undergone solid organ transplant, and almost 10% (59/641) had nosocomial COVID-19 infection. During ICU stay, 359/644 patients (55.7%) required invasive mechanical ventilation, 225 (34.9%) needed renal replacement therapy, 337 (52.2%) received vasopressors, and 216 (33.5%) had hospital-acquired infections (HAIs), mainly caused by multidrug-resistant gram-negative bacteria. HAIs were independently associated with a higher risk of death. The major causes of death were refractory shock and multiple organ dysfunction syndrome but not ARDS, as previously reported in the literature. Conclusions: In this study, most of our cohort required invasive mechanical ventilation and almost one third had HAIs, which were independently associated with a higher risk of death. Other factors related to death were Charlson Comorbidity Index, SOFA score at admission, and clinical complications during ICU stay. Nosocomial COVID-19 infection was not associated with death. The main immediate causes of death were refractory shock and multiple organ dysfunction syndrome.
RESUMO Objetivo: Avaliar desfechos clínicos e fatores associados à mortalidade, com foco em infecções secundárias, em pacientes com COVID-19 em estado crítico em três hospitais brasileiros durante a primeira onda da pandemia. Métodos: Estudo observacional retrospectivo envolvendo pacientes adultos com COVID-19 internados nas UTIs participantes entre março e agosto de 2020. Analisaram-se características clínicas, comorbidades, fonte de infecção por SARS-CoV-2, dados laboratoriais, dados microbiológicos, complicações e causas de óbito. Os fatores associados à mortalidade hospitalar foram avaliados por meio de modelos de regressão logística. Resultados: Foram incluídos 645 pacientes com média de idade de 61,4 anos. Desses, 387 (60,0%) eram do sexo masculino, 12,9% (83/643) haviam sido submetidos a transplante de órgão sólido, e quase 10% (59/641) apresentaram infecção nosocomial por COVID-19. Durante a internação na UTI, 359/644 pacientes (55,7%) necessitaram de ventilação mecânica invasiva, 225 (34,9%) necessitaram de terapia renal substitutiva, 337 (52,2%) receberam vasopressores, e 216 (33,5%) apresentaram infecções hospitalares (IHs), causadas principalmente por bactérias Gram-negativas multirresistentes. As IHs associaram-se de forma independente a maior risco de óbito. As principais causas de óbito foram choque refratário e síndrome de disfunção de múltiplos órgãos, mas não SDRA, como relatado anteriormente na literatura. Conclusões: Neste estudo, a maior parte de nossa coorte necessitou de ventilação mecânica invasiva, e quase um terço apresentou IHs, que se associaram de forma independente a maior risco de óbito. Outros fatores relacionados à mortalidade foram Índice de Comorbidade de Charlson, SOFA na admissão e complicações clínicas durante a internação na UTI. A infecção nosocomial por COVID-19 não se associou à mortalidade. As principais causas imediatas de óbito foram choque refratário e síndrome de disfunção de múltiplos órgãos.
