RESUMO
Abstract In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals. Furthermore, there is a lack of adequate regulation (and enforcement), public policies, and strategies to protect the kidney health of workers, considering the main risk factors. CKDnt is likely to be a significant cause of CKD in Brazil, since CKD's etiology is unknown in many patients and several conditions for its development are present in the country. Further epidemiological studies may be conducted to explore causal associations and estimate the impact of heat, pesticides, and metals on CKDnt in Brazil. Moreover, public policies should prioritize reducing workers´ exposure and promoting their health and safety.
Resumo Nas últimas décadas, uma epidemia de doença renal crônica (DRC) tem sido associada a fatores ambientais e ocupacionais (estresse térmico decorrente de cargas de trabalho elevadas em altas temperaturas e exposição a produtos químicos, como agrotóxicos e metais), denominada DRC de origem não tradicional (DRCnt). Esta revisão descritiva tem como objetivo apresentar evidências recentes sobre estresse térmico, agrotóxicos e metais como possíveis causas de DRCnt e fornecer uma visão geral das estratégias brasileiras de regulamentação, fiscalização e vigilância sanitária relacionadas. Os trabalhadores brasileiros são comumente expostos a condições extremas de calor e outros fatores de risco de DRCnt, incluindo o aumento da exposição a agrotóxicos e metais. Além disso, há uma falta de regulamentação e fiscalização, políticas públicas e estratégias adequadas para proteger a saúde renal dos trabalhadores em relação aos principais fatores de risco. É provável que a DRCnt seja uma causa significativa de DRC no Brasil, uma vez que a etiologia da doença é desconhecida em muitos pacientes e diversas condições para seu desenvolvimento estão presentes no país. Estudos epidemiológicos devem ser realizados para explorar associações causais e estimar o impacto do calor, dos agrotóxicos e dos metais na DRCnt no Brasil. Além disso, as políticas públicas devem priorizar a redução da exposição dos trabalhadores e a promoção de sua saúde e segurança.
RESUMO
Las duplicaciones del tracto alimentario son un conjunto heterogéneo de anomalías congénitas del tubo digestivo. Su forma de presentación es variada, y pueden desarrollar distintas complicaciones libradas a su evolución natural. La infección es una complicación poco frecuente, pero que no puede desconocerse por la gravedad que implica. Se presenta el caso de una paciente de 2 años de edad, previamente sana, con una complicación atípica de una duplicación del tracto alimentario: un shock séptico. Consultó inicialmente por distensión y dolor abdominal asociado a una masa abdominal palpable. Los estudios imagenológicos evidenciaron una formación líquida parcialmente tabicada en el hemiabdomen derecho. Durante la internación, se presentó una infección intratumoral, que evolucionó al shock séptico. Respondió favorablemente al tratamiento médico del shock, y se realizó la exéresis quirúrgica posteriormente. La anatomía patológica confirmó la duplicación del tracto alimentario.
Alimentary tract duplications are heterogenous congenital anomalies of the digestive tract. Their form of presentation is varied, and they may lead to different complications, depending on their natural course. Infection is a rare complication, but it cannot be ignored because of its severity. Here we describe the case of an otherwise healthy 2-year-old girl with an atypical complication of alimentary tract duplication: septic shock. She initially consulted due to abdominal distension and pain associated with a palpable abdominal mass. The imaging studies showed a partial fluid septation in the right side of the abdomen. During hospitalization, an intratumoral infection developed, which progressed to septic shock. The patient responded favorably to medical treatment for shock, and surgical resection was subsequently performed. The pathology report confirmed the presence of alimentary tract duplication.

Objetivo: A síndrome do choque tóxico (SCT) é uma condição multissistêmica grave, causada por Staphylococcus aureus ou Streptococcus pyogenes,e o manejo inicial e contínuo das lesões de pele é essencial para o controle da infecção. Este relato teve o objetivo de descrever os cuidados com a pele nessa síndrome. Relato do caso: Paciente do sexo masculino com abscesso no quadril que evoluiu com febre e hipotensão e consequente transferência para a Unidade de Terapia Intensiva (UTI). Foi diagnosticado com choque séptico de provável foco no quadril, imediatamente abordado cirurgicamente para tratamento local da infecção. Apresentou insuficiência renal, além de disfunção multissistêmica (hepática e cardíaca), instabilidade hemodinâmnica e lesões disseminadas de pele. Com o isolamento do Staphylococcus aureus, iniciou-se clindamicina e o diagnóstico foi de SCT, uma vez que apresentou lesões epidermolíticas desde o início do quadro. Foram iniciadas medidas de recuperação cutânea com a sulfadiazina de prata e, posteriormente, com hidrofibra com prata com restauração do epitélio em 8 dias. Após 10 dias da pele restaurada, o paciente recebeu alta da UTI para enfermaria com manutenção do tratamento proposto. Conclusão: Neste caso, o uso da hidrofibra obteve uma performancesatisfatória, contudo ainda há necessidade de estudos robustos que comprovem tal eficácia. (AU)
Objective: Toxic shock syndrome (TSS) is a severe multisystemic condition caused by Staphylococcus aureus or Streptococcus pyogenes, and initial management of skin lesions is essential for infection control. This article aimed to describe skin care for TSS. Case report: We report a man with a hip abscess who developed fever and hypotension and was subsequently transferred to an intensive care unit (ICU). He was diagnosed with septic shock, probably of hip origin, and was immediately treated surgically for local infection control. He presented with renal failure besides multiple organ dysfunction (hepatic and cardiac), hemodynamic instability, and disseminated skin lesions. With the isolation of Staphylococcus aureus, clindamycin was initiated, and the diagnosis was TSS due to epidermolytic lesions since the onset of the condition. Cutaneous recovery measures were initiated with silver sulfadiazine, followed by silver hydrofiber with skin recovery in 8 days. After 10 days of skin recovery, the patient was discharged from the ICU to the ward with maintenance of the proposed treatment. Conclusion: In this case, the use of hydrofiber showed satisfactory performance; however, robust studies are needed to confirm such efficacy. (AU)

La sepsis es un problema global de salud y la progresión hacia el shock séptico se asocia con un incremento marcado de la morbimortalidad. En este escenario, el aumento del lactato plasmático demostró ser un indicador de gravedad y un predictor de mortalidad, y suele interpretarse casi exclusivamente como marcador de baja perfusión tisular. Sin embargo, últimamente se produjo un cambio de paradigma en la exégesis del metabolismo y propiedades biológicas del lactato. En efecto, la adaptación metabólica al estrés, aun con adecuado aporte de oxígeno, puede justificar la elevación del lactato circulante. Asimismo, otras consecuencias fisiopatológicas de la sepsis, como la disfunción mitocondrial, se asocian con el desarrollo de hiperlactatemia sin que necesariamente se acompañen de baja perfusión tisular. Interpretar el origen y la función del lactato puede resultar de suma utilidad clínica en la sepsis, especialmente cuando sus niveles circulantes fundamentan las medidas de reanimación.
Sepsis is a global health problem; progression to septic shock is associated with a marked increase in morbidity and mortality. In this setting, increased plasma lactate levels demonstrated to be an indicator of severity and a predictor of mortality, and are usually interpreted almost exclusively as a marker of low tissue perfusion. However, a recent paradigm shift has occurred in the exegesis of lactate metabolism and its biological properties. Indeed, metabolic adaptation to stress, even with an adequate oxygen supply, may account for high circulating lactate levels. Likewise, other pathophysiological consequences of sepsis, such as mitochondrial dysfunction, are associated with the development of hyperlactatemia, which is not necessarily accompanied by low tissue perfusion. Interpreting the origin and function of lactate may be of great clinical utility in sepsis, especially when circulating lactate levels are the basis for resuscitative measures.

Introducción. El objetivo del estudio fue analizar el impacto del uso de la tomografía corporal total en la evaluación de los pacientes con trauma penetrante por proyectil de arma de fuego y hemodinámicamente inestables atendidos en un centro de referencia de trauma. Métodos. Se realizó un estudio analítico, retrospectivo, con base en un subanálisis del registro de la Sociedad Panamericana de Trauma Fundación Valle del Lili. Se incluyeron los pacientes con trauma penetrante por proyectil de arma de fuego atendidos entre 2018 y 2021. Se excluyeron los pacientes con trauma craneoencefálico severo, trauma leve y en condición in extremis. Resultados. Doscientos pacientes cumplieron los criterios de elegibilidad, 115 fueron estudiados con tomografía corporal total y se compararon con 85 controles. La mortalidad intrahospitalaria en el grupo de tomografía fue de 4/115 (3,5 %) vs 10/85 (12 %) en el grupo control. En el análisis multivariado se identificó que la tomografía no tenía asociación significativa con la mortalidad (aOR=0,46; IC95% 0,10-1,94). El grupo de tomografía tuvo una reducción relativa del 39 % en la frecuencia de cirugías mayores, con un efecto asociado en la disminución de la necesidad de cirugía (aOR=0,47; IC95% 0,22-0,98). Conclusiones. La tomografía corporal total fue empleada en el abordaje inicial de los pacientes con trauma penetrante por proyectil de arma de fuego y hemodinámicamente inestables. Su uso no se asoció con una mayor mortalidad, pero sí con una menor frecuencia de cirugías mayores.
Introduction. This study aims to assess the impact of whole-body computed tomography (WBCT) in the evaluation of patients with penetrating gunshot wounds (GSW) who are hemodynamically unstable and treated at a trauma referral center. Methods. An analytical, retrospective study was conducted based on a subanalysis of the Panamerican Trauma Society-FVL registry. Patients with GSW treated between 2018 and 2021 were included. Patients with severe cranioencephalic trauma, minor trauma, and those in extremis were excluded. Patients with and without WBCT were compared. The primary outcome was in-hospital mortality, and the secondary outcome was the frequency of major surgeries (thoracotomy, sternotomy, cervicotomy, and/or laparotomy) during initial care. Results. Two hundred eligible patients were included, with 115 undergoing WBCT and compared to 85 controls. In-hospital mortality in the WBCT group was 4/115 (3.5%) compared to 10/85 (12%) in the control group. Multivariate analysis showed that WBCT was not significantly associated to mortality (aOR: 0.46; 95% CI 0.10-1.94). The WBCT group had a relative reduction of 39% in the frequency of major surgeries, with an associated effect on reducing the need for surgery (aOR: 0.47; 95% CI 0.22-0.98). Conclusions. Whole-body computed tomography was employed in the initial management of patients with penetrating firearm projectile injuries and hemodynamic instability. The use of WBCT was not associated with mortality but rather with a reduction in the frequency of major surgery.

Resumo Fundamento A infecção concomitante por coronavírus 2019 (COVID-19) e o infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) estão associados ao aumento de desfechos adversos hospitalares. Objetivos O estudo teve como objetivo avaliar as diferenças angiográficas, de procedimentos, laboratoriais e prognósticas em pacientes positivos e negativos para COVID-19 com IAMCSST submetidos à intervenção coronária percutânea primária (ICP). Métodos Realizamos um estudo observacional retrospectivo e unicêntrico entre novembro de 2020 e agosto de 2022 em um hospital de nível terciário. De acordo com o seu estado, os pacientes foram divididos em dois grupos (positivo ou negativo para COVID-19). Todos os pacientes foram internados por IAMCSST confirmado e foram tratados com ICP primária. Os desfechos hospitalares e angiográficos foram comparados entre os dois grupos. P-valores bilaterais <0,05 foram aceitos como estatisticamente significativos. Resultados Dos 494 pacientes com IAMCSST inscritos nesse estudo, 42 foram identificados como positivos para COVID-19 (8,5%) e 452, como negativos. Os pacientes que testaram positivos para COVID-19 tiveram um tempo isquêmico total maior do que os pacientes que testaram negativos para COVID-19 (p = 0,006). Além disso, esses pacientes apresetaram um aumento na trombose de stent (7,1% vs. 1,7%, p = 0,002), no tempo de internação (4 dias vs. 3 dias, p = 0,018), no choque cardiogênico (14,2% vs. 5,5%, p = 0,023) e na mortalidade hospitalar total e cardíaca (p <0,001 e p = 0,032, respectivamente). Conclusões Pacientes com IAMCSST com infecções concomitantes por COVID-19 foram associados ao aumento de eventos cardíacos adversos maiores. Mais estudos são necessários para compreender os mecanismos exatos dos desfechos adversos nesses pacientes.
Abstract Background Concomitant coronavirus 2019 (COVID-19) infection and ST-segment elevation myocardial infarction (STEMI) are associated with increased adverse in-hospital outcomes. Objectives This study aimded to evaluate the angiographic, procedural, laboratory, and prognostic differences in COVID-19-positive and negative patients with STEMI undergoing primary percutaneous coronary intervention (PCI). Methods A single-center, retrospective, observational study was conducted between November 2020 and August 2022 in a tertiary-level hospital. According to their status, patients were divided into two groups (COVID-19 positive and negative). All patients were admitted due to confirmed STEMI and treated with primary PCI. In-hospital and angiographic outcomes were compared between the two groups. Two-sided p-values < 0.05 were accepted as statistically significant. Results Of the 494 STEMI patients enrolled in this study, 42 were identified as having a positive dagnosis for COVID-19 (8.5%), while 452 were negative. The patients who tested positive for COVID-19 had a longer total ischemic time than did those who tested negative for COVID-19 (p=0.006). Moreover, these patients presented an increase in stent thrombosis (7.1% vs. 1.7%, p=0.002), length of hospitalization (4 days vs. 3 days, p= 0.018), cardiogenic shock (14.2% vs. 5.5 %, p= 0.023), and in-hospital total and cardiac mortality (p<0.001 and p=0.032, respectively). Conclusions Patients with STEMI with concomitant COVID-19 infections were associated with increased major adverse cardiac events. Further studies are needed to understand the exact mechanisms of adverse outcomes in these patients.
RESUMO
RESUMEN Antecedentes: El accidente ofídico es una enfermedad desatendida que afecta a los países tropicales. América Latina es la segunda región después de África, con mayor número de casos a nivel mundial. Su curso clínico incluye lesiones locales hasta afectaciones sistémicas como lesiones renales, hematológicas y neurológicas. Las complicaciones cardiacas son raras, especialmente en pacientes que no tienen factores de riesgo cardiovascular. Hay reportes de infarto agudo de miocardio, pero existe poca información sobre la insuficiencia cardíaca debida a Bothrops spp. Reporte de caso: Presentamos el caso de un hombre de 25 años sin factores de riesgo cardiovascular que fue admitido en la unidad de cuidados intensivos y desarrolló insuficiencia cardíaca con choque cardiogénico y fallo multiorgánico secundario a una mordedura de serpiente. Conclusiones: Aunque el curso clínico característico de un accidente ofídico bothrópico y sus manifestaciones sistémicas están principalmente relacionadas con anomalías de la coagulación, hay complicaciones cardiovasculares dentro de su presentación clínica que, aunque raras, si no se detectan prontamente y no se manejan adecuadamente, están asociadas con alta morbilidad y mortalidad.
ABSTRACT Background: Ophidic accident is a neglected disease that affects tropical countries. Latin America is the second region after Africa, with the most cases worldwide. Local lesions accompany its clinical course up to systemic affectations such as renal, hematological, and neurological lesions. Cardiac complications are rare, especially in patients who do not have cardiovascular risk factors. There are reports of acute myocardial infarction, but there is little information about heart failure due to Bothrops spp. Case report: We present the case of a 25-year-old man without cardiovascular risk factors who was admitted to the intensive care unit and developed heart failure with cardiogenic shock and multi-organ failure secondary to a snake bite. Conclusions: Although the characteristic clinical course of a bothropic ophidian accident and its systemic manifestations are mainly related to coagulation abnormalities, there are cardiovascular complications within its clinical presentation that, although rare, if not detected promptly and not adequately managed, are associated with high morbidity and mortality.
RESUMO
RESUMEN El megacolon tóxico es una enfermedad mortal, que se presenta, con mayor frecuencia, como una complicación de la inflamación intestinal, infecciones e isquemia intestinal. Se caracteriza por la presencia de diarrea sanguinolenta, distensión abdominal, signos de toxicidad sistémica y, en estudios de imagen, se observa dilatación colónica segmentaria. Para el diagnóstico, según los criterios de Jalan, se tiene en cuenta la dilatación colónica más de 6 cm, tres de los siguientes: fiebre, taquicardia, leucocitosis o anemia, y cualquiera de los siguientes criterios: hipotensión, hipovolemia, trastorno electrolítico y estado mental alterado. En este artículo, se presenta el caso de una paciente mujer que ingresa por cuadro de dolor abdominal y diarrea crónica con estudio de imagen, en la que se visualiza dilatación de todo el marco colónico. Se realizan los estudios correspondientes y se diagnostica megacolon tóxico por colitis ulcerativa, por lo que recibe tratamiento médico con evolución favorable. Es dado de alta y reingresa por shock séptico, se realizan estudios y se identifica infección por Clostridium difficile. Se inicia tratamiento antibiótico, pero presenta evolución desfavorable, lo que ocasionó el fallecimiento de la paciente. El presente caso representa la alta mortalidad de esta enfermedad.
ABSTRACT Toxic megacolon is a fatal disease, most commonly occurring as a complication of inflammatory bowel disease, infections, and intestinal ischemia. It is characterized by the presence of bloody diarrhea, abdominal distension, signs of systemic toxicity, and segmental colonic dilation is observed in imaging studies. For the diagnosis, according to the Jalan criteria, colonic dilation of more than 6 cm is taken into account, three of the following: fever, tachycardia, leukocytosis or anemia, and any of the following criteria: hypotension, hypovolemia, electrolyte disorder and altered mental status. This article presents the case of a female patient who was admitted with abdominal pain and chronic diarrhea with an imaging study showing dilation of the entire colonic framework. The corresponding studies were carried out which indicated that she had a toxic megacolon due to colitis. ulcerative, receives medical treatment with favorable evolution, is discharged and readmitted for septic shock, studies are performed and Clostridium difficile infection is identified, antibiotic treatment is started but the evolution is unfavorable, which caused the death of the patient. The present case represents the high mortality of this disease.
RESUMO
@#Objective To express the molecular chaperone Acr2 protein of Mycobacterium tuberculosis(Mtb)in E.coli and analyze the function. Methods The recombinant plasmid pET-28a-Acr2 was transformed into competent E. coli BL21(DE3),and induced by IPTG. The expressed His-Acr2 protein was purified by Ni-NTA chromatography and SuperdexTM200 10/300 GL gel filtration chromatography to obtain Acr2 protein. The Acr2 protein was refolded by spontaneous refolding and reassembly after thermal denaturation(100 ℃ for 15 min)and chemical denaturation(8 mol/L urea,37 ℃ for 4 h).The secondary structure of Acr2 protein before and after denaturation-renaturation was detected by circular dichroism spectroscopy and non-denaturing SDS-PAGE,and the molecular chaperone function of Acr2 protein in vitro was detected by substrate binding assay. Results The purified Acr2 protein had the relative molecular mass of about 232 000,the purity of over 90%,and the concentration of about 2 mg/mL,which recovered its natural secondary structure after denaturationrenaturation,and formed stable complexes with the denatured malate dehydrogenase(MDH)at 48 ℃. Conclusion The Acr2protein can restore its natural molecular conformation with molecular chaperone activity in vitro after denaturation-renaturation treatment,providing a new strategy for the preparation of Mtb protein antigen with natural activity.
RESUMO
As one of the important causes of death in critically ill patients,septic shock has always been the focus of research in the field of critical care medicine.Correct and rational use of vasoactive drug is an important treatment for septic shock.The hemodynamic changes of septic shock in children and adults are different,which lead to the different use of vasoactive drugs.This review summarized the similarities and differences of the application of vasoactive drugs between children and adults with septic shock,thus could provide a reference for clinical practice.
RESUMO
The mortality rate of septic shock in children is high,and the number of cases has been increasing year by year.In recent years,the number of deaths has decreased with the development of medical technology.With the increasing number of surviving children with septic shock,the prognosis regarding these patients is gaining more attention of PICU physicians than before.The long-term sequelae of patients with septic shock,which often leads to multiple organ dysfunction and complications,severely affects the quality of children life after discharge from the hospital.Notably,the meaningful outcomes mainly include physical,mental,emotional,and social functioning.Currently,few studies focusing on quality of life in children surviving from septic shock have been reported in China.Herein,this review summarized the progress of research on the long-term prognosis of patients with septic shock.
RESUMO
Objective:To explore the clinical characteristics of children with septic shock and analyze the drug resistance of blood culture positive bacteria.Methods:The clinical data,positive blood culture strains and drug sensitivity results of 127 children with septic shock admitted to the Department of Intensive Care Medicine of Hunan Children's Hospital from September 2015 to August 2021 were retrospectively analyzed.Results:A total of 134 strains of bacteria or fungi were isolated from the blood culture samples of 127 children with septic shock,and gram-negative strains were the main ones,accounting for 67.16% (90/134).Haemophilus influenzae and Escherichia coli were the main gram-negative bacteria,accounting for 38.81% (52/134) and 20.15% (27/134),respectively,while Streptococcus pneumoniae was the main gram-positive bacteria,accounting for 8.21% (11/134),and Candida albicans was the main fungus,accounting for 10.45% (14/134).The number of white blood cells,the levels of serum C-reactive protein,procalcitonin,venous blood sugar and arterial blood lactic acid in patients were all significantly higher than normal values,and the white blood cells count and neutrophil percentage in gram-positive bacterial infections were significantly higher than those with gram-negative bacterial infections and fungal infections( P<0.05).Procalcitonin increased most obviously when infected by gram-negative bacteria,and the difference was statistically significant ( P<0.05).Gram-positive strains were sensitive to vancomycin,teicoplanin,and linezolid,but only 50% of Streptococcus pneumoniae were sensitive to penicillin.Gram-negative strains had relatively high drug resistance,among which Klebsiella pneumoniae were only highly resistant to imipenem,cilastatin and levofloxacin,reaching 50%.Haemophilus influenzae was resistant to cephalosporins and β-amides enzyme antibiotic,and the drug sensitivity rate of lactamase antibiotics was high,with a resistance rate of 50% only to ampicillin,cefuroxime,amikacin,and compound sulfamethoxazole.There were not many fungal strains,and most antifungal drugs were effective against blood culture-positive fungi. Conclusion:The main pathogens of infection in children with septic shock are gram-negative bacteria,and have high resistance to general antibiotics.We should pay attention to their drug resistance when using antibiotics empirically.
RESUMO
Objective:To study the early predictors of refractory septic shock (RSS) in neonates.Methods:From July 2020 to December 2021, clinical data of neonates with septic shock admitted to the Neonatal Department of our hospital were retrospectively reviewed. According to the maximum septic shock score (SSS) during clinical course, the neonates were assigned into RSS group and non-RSS group. Perinatal data, laboratory results and hemodynamic parameters at diagnosis were compared between the two groups. Multiple logistic regression analysis was used to identify independent risk factors of RSS and septic shock-related death. Receiver operating characteristic (ROC) curve was constructed to evaluate the early predictors of poor prognosis.Results:A total of 130 neonates were enrolled, including 54 in RSS group and 76 in non-RSS group. Compared with the non-RSS group, the RSS group had significantly lower pH, base excess (BE), stroke volume index (SVI), cardiac output (CO) and cardiac index (CI).Meanwhile, the RSS group had significantly higher mean arterial pressure (MAP) to CI ratio (MAP/CI) and SSS [including bedside SSS (bSSS), computed SSS (cSSS) and modified version of cSSS (mcSSS)] (all P<0.05). Multiple logistic regression analysis showed that increased MAP/CI was an independent predictor of RSS. The cut-off value of MAP/CI was 11.6 [sensitivity 62%, specificity 87%, positive predictive value (PPV) 79% and negative predictive value (NPV) 77%], with an area under the curve (AUC) of 0.734. Increased mcSSS was an independent predictor of septic shock-related death. The cut-off value of mcSSS was 5.8 (sensitivity 83%, specificity 72%, PPV 21% and NPV 97%), with an AUC of 0.845. Conclusions:Increased MAP/CI (≥11.6) and mcSSS (≥5.8) may be early predictors of RSS and septic shock-related death in neonates.
RESUMO
Objective:To explore the application of a role transition shock model based on the teach-back technique in knee arthroplasty nursing teaching.Methods:We assigned 50 nursing student interns practicing in the knee arthroplasty team of Orthopedics Department of Nanjing First Hospital between August 2020 and August 2022 into control group ( n=25, traditional teaching) and observation group ( n=25, teach-back-based role transition shock model teaching) according to the order of admission. At the end of internship, the examination scores, the impact of transition shock on comprehensive abilities, and teaching satisfaction of the students were assessed and analyzed using the t test and Fisher's exact test with the use of SPSS 22.0. Results:Compared with the control group, the observation group scored significantly lower in the physical, psychological, knowledge and skills, and sociocultural and developmental dimensions of the transition shock assessment scale ( P<0.05). The observation group showed significantly higher scores of nurse-patient communication, nursing practice, disease observation, health education, humanistic care, team cooperation, clinical thinking, and emergency response than the control group ( P<0.05). The examination results of the observation group were significantly better than those of the control group ( t=12.31, 11.52, P<0.001). The teaching satisfaction rate of the observation group was significantly higher than that of the control group [100.00% (25/25) vs. 68.00% (17/25), χ2=9.52, P=0.002]. Conclusions:The teach-back-based role transition shock model can help alleviate the transition impact faced by nursing student interns when entering clinical practice, and also improve their comprehensive abilities as well as satisfaction with teaching.
RESUMO
Objective To evaluate the efficacy of vitamin C intravenous injection in the treatment of patients with sepsis.Methods PubMed,Embase,Scopus,Cochrane Library,and Clinical Trial databases were retrieved,with a retrieval period from database establishment to December 2022.English literatures on randomized controlled trial(RCT)of vitamin C intravenous injection for the treatment of sepsis or septic shock were collected.Meta-analysis was conducted using RevMan 5.3 software and Stata 15.0 software after literature screening,extraction,and evalua-tion of the bias risk included in the studies by two researchers independently.Results A total of 16 RCT studies involving 3 301 patients were included in the analysis.In terms of main outcomes,the 28-day mortality of patients in the vitamin C treatment group was slightly lower than that of the control group,but the difference was not statis-tically significant(RR=0.86,95%CI[0.72-1.03],P=0.10;I2=44%,P=0.10).In terms of secondary out-comes,vitamin C intravenous injection can reduce the duration of vasoactive drug usage time(MD=-23.44,95%CI[-30.53--16.35],P<0.01;I2=0,P=0.97),but has no significant effect on the 90-day mortality,inten-sive care unit mortality,hospital mortality,duration of mechanical ventilation,difference in estimated sequential organ failure assessment score at 72 hour,length of stay in ICU,and total length of hospital stay of patients(P>0.05).Conclusion Intravenous vitamin C injection can significantly reduce vasoactive drug usage time,but the available evidence is insufficient to support that intravenous vitamin C can improve the prognosis of patients with sepsis or septic shock.More high-quality,multicenter randomized controlled trial is needed to provide more substantial evidence about the efficacy of vitamin C in treating sepsis or septic shock.

Objective:To investigate the risk factors of acute respiratory distress syndrome(ARDS)after traumatic hemorrhagic shock.Methods:This was a retrospective cohort study of 314 patients with traumatic hemorrhagic shock at Trauma Medicine Center,Peking University People's Hospital from De-cember 2012 to August 2021,including 152 male patients and 162 female patients,with a median age of 63.00(49.75-82.00)years.The demographic data,past medical history,injury assessment,vital signs,laboratory examination and other indicators of these patients during hospitalization were recorded.These patients were divided into two groups,ARDS group(n=89)and non-ARDS group(n=225)ac-cording to whether there was ARDS within 7 d of admission.Risk factors for ARDS were identified using Logistic regression.The C-statistic expressed as a percentage[area under curve(AUC)of the receiver operating characteristic(ROC)curve]was used to assess the discrimination of the model.Results:The incidence of ARDS after traumatic hemorrhagic shock was 28.34%.Finally,Logistic regression model showed that the independent risk factors of ARDS after traumatic hemorrhagic shock included male,histo-ry of coronary heart disease,high acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,road traffic accident and elevated troponin Ⅰ.The OR and 95%confidence intervals(CI)were 4.01(95%CI:1.75-9.20),5.22(95%CI:1.29-21.08),1.07(95%CI:1.02-1.57),2.53(95%CI:1.21-5.28),and 1.26(95%CI:1.02-1.57),respectively;the P values were 0.001,0.020,0.009,0.014,and 0.034,respectively.The ROC curve was used to analyze the value of each risk factor in predicting ARDS.It was found that the AUC for predicting ARDS after traumatic hemor-rhagic shock was 0.59(95%CI:0.51-0.68)formale,0.55(95%CI:0.46-0.64)for history of coronary heart disease,0.65(95%CI:0.57-0.73)for APACHE Ⅱ score,0.58(95%CI:0.50-0.67)for road traffic accident,and 0.73(95%CI:0.66-0.80)for elevated troponin Ⅰ,with an overall predictive value of 0.81(95%CI:0.74-0.88).Conclusion:The incidence of ARDS in pa-tients with traumatic hemorrhagic shock is high,and male,history of coronary heart disease,high APACHE Ⅱ score,road traffic accident and elevated troponin Ⅰ are independent risk factors for ARDS after traumatic hemorrhagic shock.Timely monitoring these indicators is conducive to early detection and treatment of ARDS after traumatic hemorrhagic shock.
RESUMO
Objective:To discuss the clinical characteristics,diagnosis processes,and treatment methods of one patient with congenital intrabdominal hernia,and to summarize the potential misconceptions during the diagnostic and treatment processes,and to improve the clinicians'awareness of this disease.Methods:The clinical data and auxiliary examination results of one patient with congenital intrabdominal hernia were collected and analyzed,and the related literatures were reviewed.Results:The patient,a 65-year-old male,sought care at the local hospital due to upper abdominal pain before 2 d;there were no significant abnormalities in the examination results at the cocal hospital;blood glucose>25 mmol·L-1.After receiving hypoglycemic,rehydration,and blood purification treatment,the condition of the patient was worsened,presenting with confusion,hypotension,and respiratory distress;the patient admitted in our hospital for further diagnosis and treatment.After admission,the patient was given despite fluid resuscitation,mechanical ventilation,and supportive treatment,but there was no improvement in the symptoms;interventional radiology was performed angiography of the abdominal artery and right femoral vein,which showed no significant vascular abnormalities in the abdomen.An abdominal paracentesis yielded a mixed bloody fluid,suggesting the concealed intraperitoneal disease;exploratory laparotomy was performed.During operation,the intrabdominal hernia with small intestine necrosis and septic shock were diagnosed,and partial small intestine resection,anastomosis,adhesiolysis,and abdominal irrigation and drainage were carried out.The patient had a good recovery and was discharged on the 14th day after operation.Conclusion:Congenital intrabdominal hernia is a very rare cause of intestinal obstruction in the adults,and high suspicion for intrabdominal hernia is one of the differential diagnosis for atypical acute abdomen;early multidisciplinary intervention can be lifesaving for the patients.
RESUMO
Objective To analyze the independent factors impacting the in-hospital prognosis of patients with septic shock,and to construct a simplified scoring system and evaluate its predictive value.Methods A retrospective analysis was carried out on 247 patients with septic shock admitted to the People's Hospital of Xinjiang Uygur Autonomous Region from January 2021 to July 2022,among whom 122 patients survived and 125 died.Univariate analysis and multivariate Cox proportional hazard regression model were used to screen the independent factors affecting in-hospital mortality of septic shock patients.The best cut-off value was ob-tained by using the receiver operating characteristics(ROC)curve,and the continuous variables were conver-ted into binary variables and assigned.Finally,a simplified scoring system was established,and its predictive efficacy for hospital death in septic shock patients was verified.Results The results of multivariate Cox pro-portional hazard regression model showed that the Glasgow coma scale(GCS)score(HR=0.929,95%CI:0.875-0.985,P=0.014),quick sequential organ failure assessment(qSOFA)score(HR=1.475,95%CI:1.094-1.989,P=0.011),lactate level(HR=1.096,95%CI:1.049-1.145,P<0.001),procalcitonin level(HR=1.009,95%CI:1.000-1.018,P=0.048),and albumin level(HR=0.958,95%CI:0.922-0.996,P=0.029)were identified as independent influencing factors for in-hospital mortality in patients with septic shock.The ROC curve showed that the simplified scoring system,based on GCS score,qSOFA score,lactate,procalcitonin,and albumin levels,exhibited an area under the curve and 95%CI of 0.866(0.822-0.910),with an optimal cutoff value of 2.5.The sensitivity and specificity were 80.0%and 78.7%,respectively.Con-clusion The simplified scoring system,based on early assessments of GCS score,qSOFA score,lactate,pro-calcitonin,and albumin levels,demonstrates substantial predictive value for in-hospital mortality in patients with septic shock.
RESUMO
Objective To investigate the expression changes and clinical significance of interleukin-1 recep-tor-associated kinase 1(IRAK1)and tumor necrosis factor receptor-associated factor 6(TRAF6)in patients with septic shock.Methods A total of 142 patients with septic shock admitted from November 2020 to No-vember 2022(septic shock group)were selected as the study subjects,and those who came to the hospital for physical examination during the same period were selected as the control group.Patients with septic shock were divided into survival group(100 cases)and death group(42 cases)according to their survival status after 28 days of hospitalization observation and treatment.The expression changes of IRAK1 and TRAF6 in pa-tients with septic shock were monitored at admission and after 2,4 and 6 days of treatment.The dynamic changes of acute physiology and chronic health evaluation Ⅱ(APACHEⅡ)score and sequential organ failure assessment(SOFA)score were recorded.Spearman correlation analysis was used to evaluate the correlation between IRAK1,TRAF6 and APACHE Ⅱ score and SOFA score in septic shock patients.The correlation be-tween IRAK1 and TRAF6 was analyzed by Pearson correlation analysis.Logistic regression was used to ana-lyze the factors influencing survival status of patients with septic shock.The diagnostic value of IRAK1 and TRAF6 in survival of patients with septic shock was analyzed by the receiver operating characteristic curve.Results The relative expression levels of IRAK1 and TRAF6 in septic shock group were significantly lower than those in control group,and APACHE Ⅱ score and SOFA score were significantly higher than those in control group,with statistical significance(P<0.05).Compared with admission,the relative expression levels of IRAK1 and TRAF6 in 2,4 and 6 days after treatment were significantly increased,while APACHE Ⅱ score and SOFA score were significantly decreased,with statistical significance(P<0.05).Compared with the death group,the relative expression levels of IRAK1 and TRAF6 in the survival group were higher at each corre-sponding time point,and the APACHE Ⅱ score and SOFA score were lower,with statistical significance(P<0.05).Correlation analysis showed that IRAK1 and TRAF6 were negatively correlated with APACHE Ⅱscores and SOFA scores in septic shock patients,while IRAK1 and TRAF6 were positively correlated(r=0.688,P<0.05).IRAK1,TRAF6 and APACHE Ⅱ scores were independent risk factors for survival of septic shock patients(P<0.05).The AUC of the combined diagnosis of IRAK1 and TRAF6 was significantly larger than that of IRAK1 alone(Z=2.044,P=0.041)and that of TRAF6 alone(Z=2.442,P=0.015).Conclusion The expression of IRAK1 and TRAF6 can evaluate the survival and prognosis of patients with septic shock.
