Efficacy of dietary supplements on mortality and clinical outcomes in adults with sepsis and septic shock: A systematic review and network meta-analysis.

AIM: The aim of this network meta-analysis (NMA) was to investigate the effects of different dietary supplements on the mortality and clinical status of adults with sepsis. METHODS: We searched PubMed, EMBASE, and the Cochrane Library Central Register of Controlled Trials until February 2023. The inclusion criteria were: 1) randomized controlled trials (RCT)s; 2) adults suffering sepsis or septic shock; 3) evaluation of short- or long-mortality; and 4) publications between 1994 and 2023. The general information of studies and details of interventions were extracted. The primary outcome was short-term mortality (<90 days), and the secondary outcomes were long-term mortality (≥90 days), length of ICU and hospital stays, and duration of mechanical ventilation (MV). The risk of bias of RCTs was assessed using the Cochrane risk of bias tool 2 (ROB2). A random effect NMA was performed to rank the effect of each intervention using a frequentist approach. RESULTS: Finally, 56 RCTs with 5957 participants met the criteria. Approximately, one-third of RCTs were low risk of bias. NMA analysis revealed that there was no treatment more effective in short- or long-term mortality than control or other interventions, except for magnesium (RR: 0.33, 95% CI: 0.14, 0.79; GRADE = low) and vitamin C (RR: 0.81, 95% CI: 0.67, 0.99; low certainty evidence), which had beneficial effects on short-term mortality. Moreover, eicosapentaenoic acid, gamma-linolenic acid, and antioxidants (EPA + GLA + AOs) combination was the most effective, and magnesium, vitamin D and vitamin C were the other effective approaches in terms of duration of MV, and ICU length of stay. There was no beneficial dietary supplement for hospital stay in these patients. CONCLUSIONS: In septic patients, none of the dietary supplements had a substantial effect on mortality except for magnesium and vitamin C, which were linked to lower short-term mortality with low certainty of evidence. Further investigation into high-quality studies with the use of dietary supplements for sepsis should be highly discouraged.

Nursing Based on Humanistic Care Concept for Continuous Blood Purification for Patients with Severe Sepsis in the Intensive Care Unit.

Context: Mortality from severe sepsis has been declining in recent years but remains a challenge worldwide because it remains the most frequent cause of death in ICUs. High-quality nursing care during a patient's CBP can play an important role in promoting a patient's physical condition. Objective: The study intended to explore the effects of nursing based on a humanistic care concept on continuous blood purification (CBP) treatment for patients with severe sepsis in an intensive care unit (ICU). Design: The research team performed a prospective randomized controlled study. Setting: The study took place at Minhang Hospital at Fudan University in Shanghai, China. Participants: Participants were 80 patients with severe sepsis who had been admitted to the ICU of the hospital and who were receiving CBP between April 2021 and December 2022. Intervention: The research team randomly divided participants into two groups according to their admission sequence, with 40 participants in each group: (1) an intervention group, the humanistic care group, who received CBP under humanistic care, and (2) a control group who received CBP under routine nursing. Outcome Measures: At baseline and postintervention, the research team: (1) measured participants' negative emotions using the Self-rating Anxiety Scale (SAS) and the Self-rating Depression scale (SDS), (2) assessed participants' hope levels using the Herth Hope Index (HHI), and (3) evaluated participants' health statuses using the Acute Physiology and Chronic Health Evaluation (APACHE-II). The team also measured the complication rate and determined participants' treatment compliance. Results: Postintervention compared to the control group, the humanistic care group's: (1) SAS and SDS scores were significantly lower, with P < .001 and P < .001, respectively; (2) HHI score was significantly higher, with P < .001; (3) APACHE-II scores and complication rate were significantly lower, with P < .001 and < .001, respectively; and (4) treatment compliance was significantly higher, with P = .0186. Conclusions: Nursing based on a humanistic care concept in ICUs can effectively alleviate the negative mood of patients with severe sepsis receiving CBP, enhance their hope levels and the treatment effect, improve their health statuses and treatment compliance, and reduce the occurrence of complications.

Complementary and alternative medicine on cognitive defects and neuroinflammation after sepsis.

Sepsis-associated encephalopathy (SAE) is a common manifestation of sepsis, ranging from mild confusion and delirium to severe cognitive impairment and deep coma. SAE is associated with higher mortality and long-term outcomes, particularly substantial declines in cognitive function. The mechanisms of SAE probably include neuroinflammation that is mediated by systemic inflammation and ischemic lesions in the brain, a disrupted blood-brain barrier, oxidative stress, neurotransmitter dysfunction, and severe microglial activation. Increasing evidence suggests that complementary and alternative medicine, especially Traditional Chinese Medicine (TCM), is favorable in alleviating cognitive decline after sepsis. Here, we summarized the studies of traditional herbal remedies, TCM formulas and acupuncture therapy in animal models of neurological dysfunctions after sepsis in recent decades and reviewed their potential mechanisms.

[Review and prospects of international clinical research in critical care medicine in 2023].

The main clinical research advances of critical care in 2023 includes: new trials of Chinese herbal medicine, hydroxocobalamin (vitamin B12), methylene blue as well glucocorticoids have shown the potential to improve outcomes of patients with sepsis and septic shock; international committees launched new global definition and managing recommendations for acute respiratory distress syndrome (ARDS). Besides, a cluster of new evidences has emerged in many aspects as following: fluid control strategy in sepsis (restrictive/liberative), antibiotic infusion strategy (continuous/intermittent), oxygen-saturation targets for mechanical ventilation (conservative/liberative), blood pressure targets after resuscitation from out-of-hospital cardiac arrest (hypotension/hypertension), blood pressure targets after successful stroke thrombectomy (intensive/conventional), and nutritional support strategies (low protein-calories/conventional protein-calories, fasting/persistent feeding before extubation). Thus, given above progress, carrying out high -quality domestic multi-center clinical registration researches, constructing shareable standardized databases, as well raising public awareness of sepsis, should be the essential steps to improve our level of intensive care medicine.

Neutrophil membrane-engineered Panax ginseng root-derived exosomes loaded miRNA 182-5p targets NOX4/Drp-1/NLRP3 signal pathway to alleviate acute lung injury in sepsis: experimental studies.

BACKGROUND: The purpose of this study was to prepare neutrophil membrane-engineered Panax ginseng root-derived exosomes (N-exo) and investigate the effects of N-exo microRNA (miRNA) 182-5p (N-exo-miRNA 182-5p) on acute lung injury (ALI) in sepsis. METHODS: Panax ginseng root-derived exosomes were separated by differential centrifugation. Neutrophil membrane engineering was performed on exo to obtain N-exo. miRNA182-5p was transmitted into N-exo by electroporation technology to obtain N-exo-miRNA 182-5p. LPS was used to establish an in-vivo and in-vitro model of ALI of sepsis to evaluate the anti-inflammatory effect of N-exo-miRNA 182-5p. RESULTS: The results of transmission electron microscope showed that exo was a double-layer membrane structure like a saucer. Nanoparticle size analysis showed that the average particle size of exo was 129.7 nm. Further, compared with exo, the level of miRNA182-5p was significantly increased in N-exo. The experimental results showed that N-exo-miRNA 182-5p significantly improved ALI via target regulation of NOX4/Drp-1/NLRP3 signal pathway in vivo and in vitro . CONCLUSION: In conclusion, this study prepared a novel engineered exosome (N-exo and N-exo-miRNA 182-5p significantly improved ALI in sepsis via target regulation of NOX4/Drp-1/NLRP3 signal pathway, providing new ideas and methods for treatment of ALI in sepsis.

Long-Term Outcomes in Older Patients with Sepsis in the ICU: A Retrospective Study.

Objective: The primary objectives of this study were to compare the characteristics of older and younger patients with sepsis and to analyze risk factors associated with 28-day and 90-day mortality in critically ill patients. Our study aimed to explore whether there are significant differences between sepsis patients in different age groups and whether these differences are related to the association between disease severity and mortality. Methods: We conducted a single-center, retrospective study of 5783 critically ill patients over 18 years of age from the Medical Information Mart for Intensive Care III database diagnosed with sepsis and admitted to the intensive care unit between 2008 and 2012. We performed a retrospective analysis, selected the Critical Care Medicine Information Mart III database, and collected data on patients with sepsis. We then collated and analyzed these data to compare differences in characteristics between older and younger patients and identify associated risk factors, which can help understand patient mortality. This approach leverages existing clinical data and avoids new experiments or data collection. Kaplan-Meier survival curve was used to assess 28-day and 90-day mortality, and a Cox proportional hazards regression model was used to evaluate the associated risk factors with 28-day and 90-day mortality. Results: Our study identified significant differences in mortality between older and younger patients with sepsis, finding that older patients had significantly higher mortality than younger patients. Furthermore, we successfully identified risk factors associated with mortality, results that have important implications for optimizing patient care and making clinical decisions. Of 5783 patients with sepsis, 2044 (35.3%) were younger than 60 years, and 3739 (64.7%) were aged 60 years or older. The 28-day mortality rate was 11.8% and 21.2% in the younger and older cohorts, respectively (P < .01). In the age-stratified analysis, the 28-day mortality was the highest in patients aged over 80 years (14.6% vs. 21.2% vs. 26.8%, P < .001). Factors associated with 28-day and 90-day mortality in patients with sepsis included age, weight, the need for mechanical ventilation, congestive heart failure, chronic pulmonary disease, malignancy, and Sequential Organ Failure Assessment score. Higher mortality in older patients with sepsis suggests the need for more aggressive treatment and monitoring. We also identified risk factors associated with mortality, helping to develop individualized treatment strategies. In addition, the different clinical characteristics of patients in different age groups emphasize the need for refined care pathways to meet their special needs. These results will help improve the treatment effect and quality of life of patients with sepsis. Conclusions: Our study fills the knowledge gap on the manifestations of sepsis patients in different age groups and helps medical staff better predict and manage disease progression in these two groups and provide personalized treatment. This lays the foundation for future in-depth research on age-related sepsis factors and is expected to improve patient survival and recovery rates. Older patients with sepsis had higher mortality rates and adverse outcomes. The mortality rate in patients with sepsis gradually increased with age. The importance of these findings is that they can help guide patient care and clinical decision-making, particularly when dealing with older and younger patients with sepsis, to improve treatment outcomes and reduce mortality. We would like to acknowledge that there are several limitations to the study, including the selectivity of the database and the retrospective nature, which preclude inference of causal relationships. In addition, some unconsidered variables may affect the results, and missing information in the data may also have an impact on the study. Future research could further explore these issues.This study highlights the critical role of age in sepsis patient outcomes and provides a strong basis for more sophisticated care and treatment. Our findings will help save more lives and improve patients' chances of recovery, which has profound implications for future research and clinical practice in the field of sepsis.

Intragastric infusion of a liquid diet with low-methoxyl pectin alleviates fecal inconsistency and local proinflammatory cytokine expression in lipopolysaccharide-septic rats.

OBJECTIVE: Diarrhea interrupts enteral nutrition management in hospitalized patients with severe illnesses, such as sepsis. Pectin, a water-soluble dietary fiber, has the potential to maintain intestinal function and may reduce inflammatory reactions. The aim of this study was to demonstrate that the addition of low-methoxyl (LM) pectin to a liquid diet suppresses softening of stool texture and reduces tissue inflammatory responses in enteral nutrition management during sepsis. METHODS: A fat-enriched liquid diet with LM pectin (P-EN) or a liquid diet without dietary fiber (FF-EN) was given continuously to rats through a gastric catheter. Lipopolysaccharide (LPS; 10 mg/kg) was injected intraperitoneally 24 h (study 1) and 7 h (study 2) before sacrifice. RESULTS: LPS injection significantly worsened fecal property scores in rats infused with FF-EN compared with the rats given P-EN in study 1. Whereas many myeloperoxidase-positive cells infiltrated the liver, and the hepatic expressions of chemokine genes were markedly elevated 24 h after LPS administration, these findings were clearly alleviated in the LM pectin-containing liquid diet group. In study 2, protein expressions of proinflammatory cytokines, such as small intestinal tumor necrosis factor-α and hepatic interleukin-1ß, and interleukin-6, were significantly downregulated in the P-EN LPS group compared with the FF-EN LPS group. CONCLUSIONS: A liquid diet containing LM pectin allows enteral nutrition management with a low risk for diarrhea and reduces local inflammation under septic conditions.

Key pathways and genes that are altered during treatment with hyperbaric oxygen in patients with sepsis due to necrotizing soft tissue infection (HBOmic study).

BACKGROUND: For decades, the basic treatment strategies of necrotizing soft tissue infections (NSTI) have remained unchanged, primarily relying on aggressive surgical removal of infected tissue, broad-spectrum antibiotics, and supportive intensive care. One treatment strategy that has been proposed as an adjunctive measure to improve patient outcomes is hyperbaric oxygen (HBO2) treatment. HBO2 treatment has been linked to several immune modulatory effects; however, investigating these effects is complicated due to the disease's acute life-threatening nature, metabolic and cell homeostasis dependent variability in treatment effects, and heterogeneity with respect to both patient characteristics and involved pathogens. To embrace this complexity, we aimed to explore the underlying biological mechanisms of HBO2 treatment in patients with NSTI on the gene expression level. METHODS: We conducted an observational cohort study on prospective collected data, including 85 patients admitted to the intensive care unit (ICU) for NSTI. All patients were treated with one or two HBO2 treatments and had one blood sample taken before and after the intervention. Total RNAs from blood samples were extracted and mRNA purified with rRNA depletion, followed by whole-transcriptome RNA sequencing with a targeted sequencing depth of 20 million reads. A model for differentially expressed genes (DEGs) was fitted, and the functional aspects of the obtained set of genes was predicted with GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of genes and Genomes) enrichment analyses. All analyses were corrected for multiple testing with FDR. RESULTS: After sequential steps of quality control, a final of 160 biological replicates were included in the present study. We found 394 protein coding genes that were significantly DEGs between the two conditions with FDR < 0.01, of which 205 were upregulated and 189 were downregulated. The enrichment analysis of these DEGs revealed 20 GO terms in biological processes and 12 KEGG pathways that were significantly overrepresented in the upregulated DEGs, of which the term; "adaptive immune response" (GO:0002250) (FDR = 9.88E-13) and "T cell receptor signaling pathway" (hsa04660) (FDR = 1.20E-07) were the most significant. Among the downregulated DEGs two biological processes were significantly enriched, of which the GO term "apoptotic process" (GO:0006915) was the most significant (FDR = 0.001), followed by "Positive regulation of T helper 1 cell cytokine production" (GO:2000556), and "NF-kappa B signaling pathway" (hsa04064) was the only KEGG pathway that was significantly overrepresented (FDR = 0.001). CONCLUSIONS: When one or two sessions of HBO2 treatment were administered to patients with a dysregulated immune response and systemic inflammation due to NSTI, the important genes that were regulated during the intervention were involved in activation of T helper cells and downregulation of the disease-induced highly inflammatory pathway NF-κB, which was associated with a decrease in the mRNA level of pro-inflammatory factors. TRIAL REGISTRATION: Biological material was collected during the INFECT study, registered at ClinicalTrials.gov (NCT01790698).

[Clinical study of evaluating the clinical effect of Dachengqi decoction in the treatment of sepsis complication with gastrointestinal dysfunction via gastric antrum cross-sectional area measured by bedside ultrasound].

OBJECTIVE: To evaluate the clinical value of Dachengqi decoction in the treatment of sepsis complication with gastrointestinal dysfunction via gastric antrum cross-sectional area (CSA) measured by bedside ultrasound. METHODS: A parallel group randomized controlled trial was conducted. A total of 80 patients with sepsis with gastrointestinal dysfunction admitted to the Second Affiliated Hospital of Nanjing University of Chinese Medicine from January 2021 to October 2022 were enrolled. According to whether patients agree to use Dachengqi decoction after admission, all patients were divided into Dachengqi decoction group (observation group) and conventional treatment group (control group) by 1 : 1 randomization, each group has 40 patients. Both groups were treated with fluid resuscitation, anti-infection, maintaining stable respiratory circulation, early nourishing feeding, promoting gastrointestinal motility, and regulating intestinal flora. The observation group was treated with Dachengqi decoction on the basis of western medicine, 30 mL decoction was taken in the morning and evening. Both groups were treated for 7 days. The CSA of the two groups was measured by bedside ultrasound before and after treatment. The gastric residual volume (GRV1 and GRV2) were calculated by formula and traditional gastric tube withdrawal method. The gastrointestinal dysfunction score, acute physiology and chronic health evaluation II (APACHE II), intraperitoneal pressure (IAP), serum preprotein (PA), albumin (Alb), white blood cell count (WBC), procalcitonin (PCT), hypersensitivity C-reactive protein (hs-CRP), length of intensive care unit (ICU) stay and incidence of aspiration were detected to evaluate the clinical efficacy of Dachengqi decoction, the correlation and advantages and disadvantages between CSA measured by bedside ultrasound and other evaluation indicators of gastrointestinal dysfunction in sepsis were also analyzed. RESULTS: There were no significant differences in the indicators before treatment between the two groups, which were comparable. In comparison with the pre-treatment period, CSA, GRV, gastrointestinal dysfunction score, APACHE II score, IAP, WBC, PCT, and hs-CRP of the two groups after treatment were significantly decreased, PA and Alb were significantly increased, and the observation group decreased or increased more significantly than the control group [CSA (cm2): 4.53±1.56 vs. 6.04±2.52, GRV1 (mL): 39.85±8.21 vs. 53.05±11.73, GRV2 (mL): 29.22±5.20 vs. 40.91±8.97, gastrointestinal dysfunction score: 0.87±0.19 vs. 1.35±0.26, APACHE II score: 11.54±3.43 vs. 14.28±3.07, IAP (cmH2O, 1 cmH2O ≈ 0.098 kPa): 9.79±2.01 vs. 13.30±2.73, WBC (×109/L): 9.35±1.24 vs. 12.35±1.36, PCT (µg/L): 3.68±1.12 vs. 6.43±1.45, hs-CRP (mg/L): 24.76±5.41 vs. 46.76±6.38, PA (mg/L): 370.29±45.89 vs. 258.33±34.58, Alb (g/L): 38.83±5.64 vs. 33.20±4.98, all P < 0.05]. The length of ICU stay (days: 10.56±3.19 vs. 14.24±3.45) and incidence of aspiration (12.5% vs. 25.0%) were lower than those in the control group (both P < 0.05). Correlation analysis showed that CSA measured by bedside ultrasound was positively correlated with GRV2, gastrointestinal dysfunction score, APACHE II score, and IAP (r values were 0.84, 0.78, 0.75, 0.72, all P < 0.01) and negatively correlated with PA and Alb (r values were -0.64 and -0.62, both P < 0.01). CONCLUSIONS: The Dachengqi decoction can significantly improve the clinical symptoms of septic patients with gastrointestinal dysfunction, reduce systemic inflammatory response, improve nutritional status, and shorten ICU hospital stay. Bedside ultrasound monitoring of CSA is a simple, accurate and effective means to evaluate gastrointestinal dysfunction, which is worthy of further clinical promotion.

Unmasking the complex roles of hypocalcemia in cancer, COVID-19, and sepsis: Engineered nanodelivery and diagnosis.

Calcium (Ca2+) homeostasis is essential for maintaining physiological processes in the body. Disruptions in Ca2+ signaling can lead to various pathological conditions including inflammation, fibrosis, impaired immune function, and accelerated senescence. Hypocalcemia, a common symptom in diseases such as acute respiratory distress syndrome (ARDS), cancer, septic shock, and COVID-19, can have both potential protective and detrimental effects. This article explores the multifaceted role of Ca2+ dysregulation in inflammation, fibrosis, impaired immune function, and accelerated senescence, contributing to disease severity. Targeting Ca2+ signaling pathways may provide opportunities to develop novel therapeutics for age-related diseases and combat viral infections. However, the role of Ca2+ in viral infections is complex, and evidence suggests that hypocalcemia may have a protective effect against certain viruses, while changes in Ca2+ homeostasis can influence susceptibility to viral infections. The effectiveness and safety of Ca2+ supplements in COVID-19 patients remain a subject of ongoing research and debate. Further investigations are needed to understand the intricate interplay between Ca2+ signaling and disease pathogenesis.

The Mechanisms of Action of Hyperbaric Oxygen in Restoring Host Homeostasis during Sepsis.

The perception of sepsis has shifted over time; however, it remains a leading cause of death worldwide. Sepsis is now recognized as an imbalance in host cellular functions triggered by the invading pathogens, both related to immune cells, endothelial function, glucose and oxygen metabolism, tissue repair and restoration. Many of these key mechanisms in sepsis are also targets of hyperbaric oxygen (HBO2) treatment. HBO2 treatment has been shown to improve survival in clinical studies on patients with necrotizing soft tissue infections as well as experimental sepsis models. High tissue oxygen tension during HBO2 treatment may affect oxidative phosphorylation in mitochondria. Oxygen is converted to energy, and, as a natural byproduct, reactive oxygen species are produced. Reactive oxygen species can act as mediators, and both these and the HBO2-mediated increase in oxygen supply have the potential to influence the cellular processes involved in sepsis. The pathophysiology of sepsis can be explained comprehensively through resistance and tolerance to infection. We argue that HBO2 treatment may protect the host from collateral tissue damage during resistance by reducing neutrophil extracellular traps, inhibiting neutrophil adhesion to vascular endothelium, reducing proinflammatory cytokines, and halting the Warburg effect, while also assisting the host in tolerance to infection by reducing iron-mediated injury and upregulating anti-inflammatory measures. Finally, we show how inflammation and oxygen-sensing pathways are connected on the cellular level in a self-reinforcing and detrimental manner in inflammatory conditions, and with support from a substantial body of studies from the literature, we conclude by demonstrating that HBO2 treatment can intervene to maintain homeostasis.

Biotherapy of experimental acute kidney injury: emerging novel therapeutic strategies.

Acute kidney injury (AKI) is a complex and heterogeneous disease with high incidence and mortality, posing a serious threat to human life and health. Usually, in clinical practice, AKI is caused by crush injury, nephrotoxin exposure, ischemia-reperfusion injury, or sepsis. Therefore, most AKI models for pharmacological experimentation are based on this. The current research promises to develop new biological therapies, including antibody therapy, non-antibody protein therapy, cell therapy, and RNA therapy, that could help mitigate the development of AKI. These approaches can promote renal repair and improve systemic hemodynamics after renal injury by reducing oxidative stress, inflammatory response, organelles damage, and cell death, or activating cytoprotective mechanisms. However, no candidate drugs for AKI prevention or treatment have been successfully translated from bench to bedside. This article summarizes the latest progress in AKI biotherapy, focusing on potential clinical targets and novel treatment strategies that merit further investigation in future pre-clinical and clinical studies.

Cost-Effectiveness of Cell Salvage in Trauma Blood Transfusions.

INTRODUCTION: Despite the increasing amount of evidence supporting its use, cell salvage (CS) remains an underutilized resource in operative trauma care in many hospitals. We aim to evaluate the utilization of CS in adult trauma patients and associated outcomes to provide evidence-based recommendations. METHODS: A systematic review was conducted using PubMed, Google Scholar, and CINAHL. Articles evaluating clinical outcomes and the cost-effectiveness of trauma patients utilizing CS were included. The primary study outcome was mortality rates. The secondary outcomes included complication rates (sepsis and infection) and ICU-LOS. The tertiary outcome was the cost-effectiveness of CS. RESULTS: This systematic review included 9 studies that accounted for a total of 1119 patients that received both CS and allogeneic transfusion (n = 519), vs allogeneic blood transfusions only (n = 601). In-hospital mortality rates ranged from 13% to 67% in patients where CS was used vs 6%-65% in those receiving allogeneic transfusions only; however, these findings were not significantly different (P = .21-.56). Similarly, no significant differences were found between sepsis and infection rates or ICU-LOS in those patients where CS usage was compared to allogeneic transfusions alone. Of the 4 studies that provided comparisons on cost, 3 found the use of CS to be significantly more cost-effective. CONCLUSIONS: Cell salvage can be used as an effective method of blood transfusion for trauma patients without compromising patient outcomes, in addition to its possible cost advantages. Future studies are needed to further investigate the long-term effects of cell salvage utilization in trauma patients.

Hypothermia or hyperthermia, which is associated with patient outcomes in critically ill children with sepsis? -A retrospective study.

OBJECTIVES: In the early stage of sepsis, identifying high-risk paediatric patients with a poor prognosis and providing timely and adequate treatment are critical. This study aimed to evaluate the effect of average body temperature within 24 hours of admission on the short-term prognosis of paediatric patients with sepsis. DESIGN: A retrospective cohort study. SETTING: A single-centre, tertiary care hospital in China, containing patient data from 2010 to 2018. PARTICIPANTS: 1144 patients with sepsis were included. INTERVENTION: None. PRIMARY AND SECONDARY OUTCOME MEASURES: The main outcome measure was in-hospital mortality, which was defined as death from any cause during hospitalisation. The secondary outcome was the length of hospital stay. RESULTS: The LOWESS method showed a roughly 'U'-shaped relationship between body temperature on the first day and in-hospital mortality. Multivariate logistic regression showed that severe hypothermia (OR 14.72, 95% CI 4.84 to 44.75), mild hypothermia (OR 3.71, 95% CI 1.26 to 10.90), mild hyperthermia (OR 3.41, 95% CI 1.17 to 9.90) and severe hyperthermia (OR 5.15, 95% CI 1.84 to 14.43) were independent risk factors for in-hospital mortality. Compared with other variables, the Wald χ2 value of temperature on the first day minus the degree of freedom was the highest. CONCLUSIONS: Whether hypothermic or hyperthermic, the more abnormal the temperature on the first day is, the higher the risk of in-hospital death in children with sepsis.

Comparison lecture and concept map methods on the level of learning and satisfaction in puerperal sepsis education of midwifery students: a quasi-experimental study.

BACKGROUND: Education and training about emergency cases are necessary for different medical groups such as midwives. Teaching puerperal sepsis is important for midwives. The teaching method is one of the challenges of the educational system in universities. This study was conducted to compare lecture and concept map methods on the level of learning and satisfaction in puerperal sepsis education of midwifery students. METHOD: This semi-experimental study was conducted in 2022 at Ardabil Nursing and Midwifery School on 50 midwifery students. Students randomly were placed in lecture and concept map teaching groups. To collect data, a 23-question satisfaction questionnaire and a 15-question test taken from the WHO books on the management of puerperal sepsis were used to check students' knowledge and learning. The data were analyzed by using descriptive statistics and independent and paired t-test SPSS software. FINDINGS: The average learning score of the students after teaching in the concept map group was 10.28 ± 1.90 and the lecture group 9.20 ± 1.70, the difference was statistically significant (p = 0.04). The average satisfaction score in the concept map group was 107.92 ± 4.46 and in the lecture group 105.68 ± 6.84, this difference was statistically significant (p = 0.03). CONCLUSION: The teaching of puerperal sepsis with the concept map method had a greater effect on the learning and satisfaction of midwifery students. Therefore, it is recommended to use this educational method.

Efficacy and safety of acupuncture as a complementary therapy for sepsis: a systematic review and meta-analysis.

BACKGROUND: Sepsis is a life-threatening organ dysfunction caused by dysregulation of the host response to infection. Acupuncture is used for treatment of inflammatory diseases; however, its effectiveness and safety as a complementary therapy for sepsis has not been fully explored. METHODS: Data were retrieved from eight databases. Randomized controlled trials (RCTs) that compared acupuncture plus conventional therapies versus conventional therapies alone were included. Pre-specified primary outcomes were mortality at 28 days and Acute Physiologic and Chronic Health Evaluation (APACHE) II scores. RESULTS: A total of 17 studies with 1099 participants were included in this study. In terms of the primary outcomes, acupuncture plus routine therapy reduced mortality at 28 days (risk ratio (RR)): 0.69, 95% confidence interval (CI): 0.52 to 0.91, p < 0.001) and APACHE II scores (mean difference (MD): -2.84, 95% CI: -4.09 to -1.58, p < 0.001) at day 7 after treatment compared with routine therapy alone. In terms of secondary outcomes, acupuncture plus routine therapy reduced white blood cell counts and levels of procalcitonin (PCT), tumor necrosis factor (TNF)-α, interleukin (IL)-6 and lactic acid and intra-abdominal pressure (IAP), and improved CD3+, CD4+ and monocytes of human leukocyte antigen (HLA)-DR at day 7 after treatment compared with routine therapy alone. However, acupuncture plus routine therapy had no significant effects on levels of IL-10, C-reactive protein (CRP), CD8+ and CD4+/CD8+ ratios compared with routine therapy alone. Quality of evidence was low to very low for all parameters (GRADE). CONCLUSION: The available evidence showed that combination of acupuncture and routine therapy may have benefit for sepsis compared with use of routine therapy only. Due to the low degree of certainty regarding its effects, further research is required. TRIAL REGISTRATION NUMBER: ICRD42019141491 (PROSPERO).

Adrenal sympathetic nerve mediated the anti-inflammatory effect of electroacupuncture at ST25 acupoint in a rat model of sepsis.

Acupuncture plays a vital anti-inflammatory action in sepsis by activating autonomic nerve anti-inflammatory pathways, such as sympathoadrenal medullary pathway, but the mechanism remains unclear. This study aims to explore the optimum parameter of electroacupuncture (EA) stimulation in regulating the sympathoadrenal medullary pathway and evaluate EA's anti-inflammatory effect on sepsis. To determine the optimum parameter of EA at homotopic acupoint on adrenal sympathetic activity, the left adrenal sympathetic nerve firing rate evoked by different intensities of single shock electrical stimulation (ES) at ST25 in healthy male Sprague-Dawley rats were evaluated by in vivo electrophysiological recording, and the levels of norepinephrine (NE) and its metabolites normetanephrine (NMN) were also examined using mass spectrometry. To verify the role of EA at ST25 in sepsis, the rats were given an intraperitoneal injection of lipopolysaccharide (LPS) to induce sepsis model, and survival rate, clinical score, and the level of interleukin (IL)-6, IL-1ß, and IL-10 were evaluated after EA application. We observed that 3 mA is the optimal intensity for activating adrenal sympathetic nerve, which significantly elevated the level of NE in the peripheral blood. For LPS-treated rats, EA at the ST25 apparently increased the survival rate and improved the clinical score compared to the control group. Furthermore, 3 mA EA at ST25 significantly decreased pro-inflammatory cytokines IL-6 and IL-1ß and upregulated anti-inflammatory cytokine IL-10 compared to the LPS-treated group. Overall, our data suggested that 3 mA is the optimal EA intensity at ST25 to activate the sympathoadrenal medullary pathway and exert an anti-inflammatory effect in sepsis.

Sepsis, critical illness, communication, swallowing and Sustainable Development Goals 3, 4, 10.

PURPOSE: Sepsis is a major global health problem with an estimated 49 million cases globally each year causing as many as 11 million deaths. The primary objective of this commentary is to describe the impacts of sepsis and critical illness on communication and swallowing function, and to discuss management strategies considering the Sustainable Development Goals (SDGs). RESULT: Communication and swallowing disabilities can occur with sepsis and critical illness. A holistic framework to optimise function, recovery, and future research priorities across the lifespan can be developed through the SDGs. CONCLUSION: Communication and swallowing disabilities following critical illness associated with sepsis have global impacts. Early multidisciplinary engagement is key to optimising individuals' function. Collaborative research, education, and public awareness is urgently needed to increase equity in health outcomes across populations. This commentary paper supports progress towards good health and well-being (SDG 3), quality education (SDG 4) and reduced inequalities (SDG 10).

Electroacupuncture alleviates cognitive dysfunction and neuronal pyroptosis in septic mice.

BACKGROUND: Sepsis is defined as organ dysfunction caused by an uncontrolled response to infection and is followed by a high incidence of cognitive dysfunction, which can severely affect patients' quality of life. Previous studies have suggested that electroacupuncture (EA) is protective against sepsis-associated cognitive dysfunction and that pyroptosis plays a vital role in cognitive function. The aim of this study was to investigate the effect of EA on cognition and neuronal pyroptosis in a mouse model of sepsis. METHODS: Sepsis was induced by cecal ligation and puncture (CLP) surgery. Mice were randomly divided into three groups (control, CLP and CLP + EA). EA was performed at bilateral ST36 for three consecutive days after the surgery. The 7-day survival rate of each group was observed on the seventh day after the surgery. The Morris water maze (MWM) was used to test cognitive function from the 8th to 12th day after the surgery. We used transmission electron microscopy (TEM) and transferase dUTP nick-end labeling (TUNEL) staining to determine the structural integrity of hippocampal neuronal membranes and the number of surviving neurons in the hippocampal tissues, respectively. Expression of nucleotide-binding domain-like receptor protein 1 (NLRP1), caspase-1 and gasdermin-D (GSDM D) in hippocampal CA1 neurons was detected by Western blotting and real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), and caspase-1 concentrations were measured by enzyme-linked immunosorbent assay. RESULTS: Compared with the CLP group, 7-day survival rates and cognitive function were significantly improved in the CLP + EA group. After EA treatment, the integrity of the hippocampal CA1 neuronal membrane and mortality of hippocampal neurons were significantly decreased, and expression of NLRP1, caspase-1 and GSDM D was downregulated. CONCLUSION: EA can alleviate cognitive dysfunction and neuronal pyroptosis in septic mice.
