RESUMO

PURPOSE: The primary objective was to demonstrate the relationship between lung ultrasound (LUS) manifestations and the outcomes of intensive care unit (ICU) patients. The secondary objective was to determine the characteristics of LUS manifestations in different subgroups of ICU patients. METHODS: This prospective multi-center cohort study was conducted in 17 ICUs. A total of 1702 patients admitted between August 31, 2017 and February 16, 2019 were included. LUS was performed according to the bedside lung ultrasound in emergency (BLUE)-plus protocol, and LUS scores were calculated. Data on the outcomes and oxygenation indices were analyzed and compared between different primary indication groups. RESULTS: The LUS scores were significantly higher for non-survivors than for survivors and were significantly different between the oxygenation index groups, with higher scores in the lower oxygenation index groups. The LUS score was an independent risk factor for the 28-day mortality. The area under the receiver operating characteristic curve was 0.663 for prediction of the 28-day mortality and 0.748 for prediction of an oxygenation index ≤100. CONCLUSIONS: The LUS score based on the BLUE-plus protocol was an independent risk factor for the 28-day mortality and was important for the prediction of an oxygenation index ≤100. An early LUS score within 24 hours of ICU admission helps predicting the outcome of ICU patients.

RESUMO

BACKGROUND: Sepsis and sepsis-associated encephalopathy (SAE) are common intensive care unit (ICU) diseases; the morbidity and mortality are high. The present study analyzed the sensitivity of different diagnostic criteria of sepsis 1.0 and 3.0, epidemiological characteristics of sepsis and SAE, and explored its risk factors for death, short-term, and long-term prognosis. METHODS: The retrospective study included patients in ICU from January 2015 to June 2016. After excluding 58 patients, 175 were assigned to either an SAE or a non-SAE group (patients with sepsis but no encephalopathy). The sensitivity of the diagnostic criteria was compared between sepsis 1.0 and 3.0, respectively. Between-group differences in baseline data, Acute Physiology and Chronic Health Evaluation II score (APACHE II score), Sequential Organ Failure Assessment score (SOFA score), etiological data, biochemical indicators, and 28-day and 180-day mortality rates were analyzed. Survival outcomes and long-term prognosis were observed, and risk factors for death were analyzed through 180-day follow-up. RESULTS: The sensitivity did not differ significantly between the diagnostic criteria of sepsis 1.0 and 3.0 (P = .286). The 42.3% incidence of SAE presented a significantly high APACHE II and SOFA scores as well as 28-day mortality and 180-day mortality (all P < .001). The incidence of death was 37.1%. The multivariate stepwise regression analysis demonstrated that the risk of death in SAE group was significantly higher than the non-SAE group (P < .001). Sepsis-associated encephalopathy is a risk factor for sepsis-related death (relative risk [RR] = 2.868; 95% confidence interval: 1.730-4.754; P < .001). Although males showed a significantly high rate of 28-day and 180-day mortality (P = .035 and .045), it was not an independent risk factor for sepsis-related death (P = .072). The long-term prognosis of patients with sepsis was poor with decreased quality of life. No significant difference was observed in prognosis between the SAE and non-SAE groups (P > .05). CONCLUSION: Both diagnostic criteria cause misdiagnosis, and the sensitivity did not differ significantly. The incidence of SAE was high, and 28-day and 180-day mortality rates were significantly higher than those without SAE. Sepsis-associated encephalopathy is a risk factor for poor outcome. The overall long-term prognosis of patients with sepsis was poor, and the quality of life decreased.

RESUMO

BACKGROUND: The CD38/cADPR pathway has been found to play roles in various inflammatory conditions. However, whether CD38 plays a protective or detrimental effect in the central nervous system (CNS) is controversial. The aim of this study was to determine the effect of CD38/cADPR pathway in sepsis associated brain injury. MATERIALS AND METHODS: Male Sprague-Dawley rats were undergone cecal ligation and puncture (CLP) or sham laparotomies. NAD+, cADPR and CD38 were measured in the hippocampus of septic rats at 0, 6, 12, 24, and 48h after CLP surgery. Rats were divided into the sham, CLP group, CLP+ CD38 expression lentivirus (CLP+ CD38 LV), CLP+ CD38 interference lentivirus (CLP+ CD38 Ri), CLP+ negative control lentivirus (CLP+NC) and the CLP+8-Br-cADPR groups. The Western blots of Bcl-2, Bax and iNOS, TUNEL assays, malondialdehyde (MDA) and superoxide dismutase (SOD) assays, transmission electron microscope analysis were performed in the hippocampus of rats. RESULTS: NAD+, cADPR and CD38 levels increased significantly in the hippocampus of septic rats as early as 12-24h after CLP surgery. CD38 knockdown or blocking cADPR with 8-Br-cADPR significantly reduced apoptosis, MDA and SOD activity, iNOS expression and ultrastructural morphology damages in the hippocampus of septic rats. CONCLUSIONS: In this study, we found that the CD38/cADPR pathway was activated in sepsis associated brain injury. Blocking this pathway protected the hippocampus from apoptosis, oxidative stress and ultrastructural morphology damages in septic rats.

RESUMO

BACKGROUND: The CD38/cyclic ADP-ribose (cADPR) pathway plays a role in various central nervous system diseases and in morphine tolerance, but its role in local anesthetic intoxication is unknown. The aim of this study was to determine the role of the CD38/cADPR pathway in ropivacaine-induced convulsion. METHODS: Forty male Sprague-Dawley rats were randomly divided into five groups (n = 8 per group): sham group, ropivacaine group, ropivacaine+8-Br-cADPR (5 nmol) group, ropivacaine+8-Br-cADPR (10 nmol) group, and ropivacaine+8-Br-cADPR (20 nmol) group (no rats died). Rats were intracerebroventricularly injected with normal saline or 8-Br-cADPR 30 min before receiving an intraperitoneal injection of ropivacaine. Electroencephalography and convulsion behavior scores were recorded. The hippocampus was harvested from each group and subjected to nicotinamide adenine dinucleotide and cADPR assays, Western blotting analysis, and malondialdehyde (MDA) and superoxide dismutase (SOD) assays. RESULTS: Intraperitoneal injection of ropivacaine (33.8 mg/kg) induced convulsions in rats. CD38 and cADPR levels increased significantly following ropivacaine-induced convulsion (P = 0.031 and 0.020, respectively, compared with the sham group). Intraventricular injection of 8-Br-cADPR (5, 10, and 20 nmol) significantly prolonged convulsion latency (P = 0.037, 0.034, and 0.000, respectively), reduced convulsion duration (P = 0.005, 0.005, and 0.005, respectively), and reduced convulsion behavior scores (P = 0.015, 0.015, and 0.000, respectively). Intraventricular injection of 8-Br-cADPR (10 nmol) also increased the B-cell lymphoma-2 (Bcl-2)/Bcl-2-associated X protein ratio (P = 0.044) and reduced cleaved Caspase 3/Caspase 3 ratio, inducible nitric oxide synthase, MDA and SOD levels (P = 0.014, 0.044, 0.001, and 0.010, respectively) compared with the ropivacaine group. CONCLUSIONS: The CD38/cADPR pathway is activated in ropivacaine-induced convulsion. Inhibiting this pathway alleviates ropivacaine-induced convulsion and protects the brain from apoptosis and oxidative stress.

RESUMO

Whether the CD38/cyclic ADP-ribose (cADPR) pathway plays a protective or detrimental role in neuroinflammation remains controversial. This study aimed to determine the role of CD38 in neuroinflammation using lipopolysaccharide (LPS)-stimulated BV2 microglial cells and co-cultured Neuro-2a (N2a) cells. In monoculture experiments, BV2 cells were divided into control, CD38 interference (CD38Ri), negative control (NC), LPS, CD38Ri+LPS, NC+LPS and 8-Br-cADPR+LPS groups. In co-culture experiments, N2a cells were co-cultured with BV2 cells for 48h. Nicotinamide adenine dinucleotide (NAD+), cADPR and intracellular Ca2+ levels and CD38 expression increased significantly in LPS-stimulated BV2 cells. CD38 knockdown or 8-Br-cADPR treatment significantly reduced NAD+, cADPR and intracellular Ca2+ levels. CD38 knockdown increased iNOS and NO levels in BV2 cells without LPS treatment; however, CD38 knockdown or 8-Br-cADPR treatment reduced iNOS and NO levels in BV2 cells with LPS treatment. CD38 knockdown increased the ratio of TUNEL-positive cells and cleaved Caspase 3/Caspase 3 ratio, and decreased the Bcl-2/Bax ratio in BV2 cells without LPS treatment; however, CD38 knockdown reduced the TUNEL positivity in BV2 cells with LPS treatment. CD38 knockdown or 8-Br-cADPR inhibited TNF-α, IL-6 (interleukin-6) and IL-1ß levels in LPS-stimulated BV2 cells. Co-culture with CD38 knockdown or 8-Br-cADPR-treated BV2 cells did not influence apoptosis or iNOS expression in N2a cells. In conclusion, our results indicate that blocking the CD38/cADPR pathway reduces intracellular Ca2+, NO and the secretion of proinflammatory cytokines. CD38 knockdown exerted a detrimental effect in apoptosis and NO production in normal microglia, but played a protective role in apoptosis and NO production in LPS-stimulated microglia.

RESUMO

OBJECTIVES: This study was designed to test the effectiveness of common carotid artery sonography in comparison with transthoracic echocardiography (TTE) for cardiac output measurements to provide an easier alternative for cardiac output monitoring in the intensive care unit. METHODS: This study included 148 patients who had common carotid artery Doppler examinations and TTE performed within 8 hours of each other, and the cardiac output measurement results were compared with each other. RESULTS: The mean age of the participants ± SD was 56.8 ± 16.2 years, with male patients composing 54.7% of the cohort. There was no significant difference in carotid and TTE cardiac output between different sexes, age groups, patients with and without mechanical ventilation, and primary indication groups. The overall intraclass correlation coefficient between the carotid and TTE cardiac output was 0.537. In patients with septic shock, multiple trauma, and respiratory failure, the intraclass correlation coefficients between TTE and carotid cardiac output were 0.241, 0.061, and 0.095, respectively. CONCLUSIONS: Carotid cardiac output shows moderate agreement with TTE cardiac output; thus, its use may be considered as an alternative for estimating cardiac output in emergencies and when TTE cardiac output is unobtainable. However, in patients with septic shock, multiple trauma, and respiratory failure, the use of carotid cardiac output is not recommended.

RESUMO

This study aimed to investigate the mechanism underlying the neuroprotective effect of hemin in oxygen-glucose deprivation (OGD)-treated neurons. OGD-treated SH-SY5Y cells (human neuroblastoma cells) were used in the study. The cellular viability of SH-SY5Y cells was assessed by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and the cell apoptosis rate was determined by flow cytometry analysis with Annexin V-fluorescein isothiocyanate and propidium iodide staining with or without hemin pretreatment. Cell viability and apoptotic activation were detected after hemin administration combined with neuroglobin (Nqb), thioredoxin-1, peroxiredoxin-2, or heme oxygenase-1 siRNA transient transfection. The release of cytochrome c from mitochondria and the interaction between Ngb and cytochrome c were examined with hemin pretreatment. Hemin had a neuroprotective effect in OGD-treated SH-SY5Y cells, which was mainly mediated by the upregulation of Ngb. Moreover, the release of cytochrome c from mitochondria was inhibited by hemin-induced Ngb expression through facilitating the interaction of Ngb with cytochrome c in mitochondria. The present findings provided new insights into the neuroprotective mechanisms of hemin. It was concluded that low-dose hemin pretreatment had a neuroprotective effect in OGD-treated SH-SY5Y cells, through inhibiting cell apoptosis. The neuroprotective effects of hemin following hypoxic-ischemic neuronal damage were mainly mediated by Ngb. One underlying mechanism was hemin-induced overexpression of mitochondrial Ngb, which inhibited endogenous apoptosis via the association with cytochrome c.

RESUMO

BACKGROUND: Despite its high prevalence, morbidity, and mortality, sepsis-associated encephalopathy (SAE) is still poorly understood. The aim of this prospective and observational study was to investigate the clinical significance of calcium-binding protein A8 (S100A8) in serum and tumor necrosis factor receptor-associated factor 6 (TRAF6) in peripheral blood mononuclear cells (PBMCs) in diagnosing SAE and predicting its prognosis. METHODS: Data of septic patients were collected within 24 h after Intensive Care Unit admission from July 2014 to March 2015. Healthy medical personnel served as the control group. SAE was defined as cerebral dysfunction in the presence of sepsis that fulfilled the exclusion criteria. The biochemical indicators, Glasgow Coma Scale, Acute Physiology and Chronic Health Evaluation score II, TRAF6 in PBMC, serum S100A8, S100ß, and neuron-specific enolase were evaluated in SAE patients afresh. TRAF6 and S100A8 were also measured in the control group. RESULTS: Of the 57 enrolled patients, 29 were diagnosed with SAE. The S100A8 and TRAF6 concentrations in SAE patients were both significantly higher than that in no-encephalopathy (NE) patients, and higher in NE than that in controls (3.74 ± 3.13 vs. 1.08 ± 0.75 vs. 0.37 ± 0.14 ng/ml, P < 0.01; 3.18 ± 1.55 vs. 1.02 ± 0.63 vs. 0.47 ± 0.10, P < 0.01). S100A8 levels of 1.93 ng/ml were diagnostic of SAE with 92.90% specificity and 69.00% sensitivity in the receiver operating characteristic (ROC) curve, and the area under the curve was 0.86 (95% confidence interval [CI]: 0.76-0.95). TRAF6-relative levels of 1.44 were diagnostic of SAE with 85.70% specificity and 86.20% sensitivity, and the area under the curve was 0.94 (95% CI: 0.88-0.99). In addition, S100A8 levels of 2.41 ng/ml predicted 28-day mortality of SAE with 90.00% specificity and 73.70% sensitivity in the ROC curve, and the area under the curve was 0.88. TRAF6 relative levels of 2.94 predicted 28-day mortality of SAE with 80.00% specificity and 68.40% sensitivity, and the area under the curve was 0.77. Compared with TRAF6, the specificity of serum S100A8 in diagnosing SAE and predicting mortality was higher, although the sensitivity was low. In contrast, the TRAF6 had higher sensitivity for diagnosis. CONCLUSIONS: Peripheral blood levels of S100A8 and TRAF6 in SAE patients were elevated and might be related to the severity of SAE and predict the outcome of SAE. The efficacy and specificity of S100A8 for SAE diagnosis were superior, despite its weak sensitivity. S100A8 might be a better biomarker for diagnosis of SAE and predicting prognosis.

RESUMO

BACKGROUND: Acute lung injury (ALI) is a common complication of sepsis that is associated with high mortality. Intracellular Ca2+ overload plays an important role in the pathophysiology of sepsis-induced ALI, and cyclic adenosine diphosphate ribose (cADPR) is an important regulator of intracellular Ca2+ mobilization. The cluster of differentiation 38 (CD38)/cADPR pathway has been found to play roles in multiple inflammatory processes but its role in sepsis-induced ALI is still unknown. This study aimed to investigate whether the CD38/cADPR signaling pathway is activated in sepsis-induced ALI and whether blocking cADPR-mediated calcium overload attenuates ALI. METHODS: Septic rat models were established by cecal ligation and puncture (CLP). Rats were divided into the sham group, the CLP group, and the CLP+ 8-bromo-cyclic adenosine diphosphate ribose (8-Br-cADPR) group. Nicotinamide adenine dinucleotide (NAD+), cADPR, CD38, and intracellular Ca2+ levels in the lung tissues were measured at 6, 12, 24, and 48 h after CLP surgery. Lung histologic injury, tumor necrosis factor (TNF)-µ, malondialdehyde (MDA) levels, and superoxide dismutase (SOD) activities were measured. RESULTS: NAD+, cADPR, CD38, and intracellular Ca2+ levels in the lungs of septic rats increased significantly at 24 h after CLP surgery. Treatment with 8-Br-cADPR, a specific inhibitor of cADPR, significantly reduced intracellular Ca2+ levels (P = 0.007), attenuated lung histological injury (P = 0.023), reduced TNF-µ and MDA levels (P < 0.001 and P = 0.002, respectively) and recovered SOD activity (P = 0.031) in the lungs of septic rats. CONCLUSIONS: The CD38/cADPR pathway is activated in the lungs of septic rats, and blocking cADPR-mediated calcium overload with 8-Br-cADPR protects against sepsis-induced ALI.

RESUMO

BACKGROUND: Although the nicotinamide adenine dinucleotide (NAD(+))/CD38/cyclic ADP ribose (cADPR)/Ca(2+) signaling pathway has been shown to regulate intracellular calcium homeostasis and functions in multiple inflammatory processes, its role in sepsis remains unknown. The aim of this study was to determine whether the NAD(+)/CD38/cADPR/Ca(2+) signaling pathway is activated during sepsis and whether an inhibitor of this pathway, 8-Br-cADPR, protects the organs from sepsis-induced damage. MATERIALS AND METHODS: Male Sprague-Dawley rats were subjected to cecal ligation and puncture (CLP) or sham laparotomies. NAD(+), cADPR, CD38, and intracellular Ca(2+) levels were measured in the hearts, livers, and kidneys of septic rats at 0, 6, 12, 24, and 48 h after CLP surgery. Rats were also divided into sham, CLP, and CLP+8-Br-cADPR groups, and the hearts, livers, and kidneys were hematoxylin-eosin-stained and assayed for malondialdehyde and superoxide dismutase activities. RESULTS: NAD(+), cADPR, CD38, and intracellular Ca(2+) levels increased in the hearts, livers, and kidneys of septic rats as early as 6-24 h after CLP surgery. Treatment with 8-Br-cADPR inhibited sepsis-induced intracellular Ca(2+) mobilization, attenuated tissue injury, reduced malondialdehyde levels, and increased superoxide dismutase activity in septic rats. CONCLUSIONS: The NAD(+)/CD38/cADPR/Ca(2+) signaling pathway was activated during sepsis in the CLP rat model. Blocking this pathway with 8-Br-cADPR protected hearts, livers, and kidneys from sepsis-induced damage.

RESUMO

Sarcophagus beetles, which can not be replaced by Diptera, play a pivotal role not only in estimating PMI of dry human skeletal remains in the later stages decomposition of carcasses, but also the corruption, destruction, decomposition and posture changes of carcasses. This article explicates the succession of sarcophagus beetles on carrion and its influencing factors, and introduces the application and prospects of sarcophagus beetles in forensic entomology. Although few researches focus on sarcophagus beetles at present, it is believed that more and more forensic scientists will pay attention to sarcophagus beetles' application in forensic identification.
