Unveiling the Causal Association between Non-Infectious Respiratory Disorders and Sepsis through Mendelian Randomization Analysis.

BACKGROUND: The association between sepsis and non-infectious respiratory diseases is well-documented, yet the specific causal link between the two remains unclear. In order to explore this relationship further, we employed a Mendelian randomization (MR) analysis utilizing data from the UK Biobank and FinnGen Biobank. METHODS: We analyzed the summary statistics of a genome-wide association study (GWAS) summary statistics for chronic obstructive pulmonary disease (COPD), asthma, pulmonary embolism (PE), idiopathic pulmonary fibrosis (IPF), obstructive sleep apnea (OSA), lung cancer, sepsis, and sepsis-related mortality. We employed the inverse-variance weighted (IVW) method and four additional MR methods. Heterogeneity and horizontal pleiotropy were assessed using the Cochrane's Q test, MR-Egger intercept, and MR-PRESSO test. A sensitivity analysis was also performed. RESULTS: MR analysis showed associations between COPD and lung cancer with increased sepsis risk (odds ratio (OR)IVW 1.138, P = 0.006; (OR)IVW 1.123, P = 0.031; respectively) and sepsis mortality ((OR)IVW 1.350, P = 0.022; (OR)IVW 1.312, P = 0.022; respectively). Asthma exhibited a potential protective effect against sepsis mortality((OR)IVW = 0.300, P = 0.039), while PE demonstrated a risk effect ((OR)IVW = 1.148, P = 0.032). No causal association was observed between asthma, PE, and sepsis (P > 0.05). IPF and OSA were not significantly associated with sepsis or sepsis-related mortality (P > 0.05). Heterogeneity and horizontal pleiotropy were not evident for asthma or lung cancer (P > 0.05). However, horizontal pleiotropy was suggested for COPD by the MR-Egger regression (P < 0.05), but not by the MR-PRESSO test (P > 0.05). IPF and OSA were not significantly associated with sepsis or sepsis-related mortality (P > 0.05). CONCLUSIONS: Our MR analysis offers new insights into potential links between noninfectious respiratory diseases and the risk of sepsis. However, additional investigation into the underlying mechanisms and clinical studies are necessary to confirm these findings.

Obstructive Fibrinous Tracheal Pseudomembrane Following Repeated Intratracheal Interventions.

Obstructive fibrinous tracheal pseudomembrane (OFTP) is a relatively rare complication of endotracheal intubation. Despite being well documented, the exact pathogenesis of OFTP remains unclear. Some studies suggest that it may arise from the early stage of ischemic tracheal wall injury caused by the cuff pressure during intubation. Diagnosis and treatment of OFTP can be facilitated through therapeutic bronchoscopy. In this case report, we describe a patient who presented with dyspnea following repeated intratracheal interventions and was diagnosed with OFTP. The patient was successfully treated with bronchoscopic cryotherapy and was subsequently discharged from the hospital.

Proteomic characteristics of the treatment trajectory of patients with COVID-19.

The ongoing COVID-19 pandemic caused by SARS-CoV-2 has prompted global concern due to its profound impact on public health and the economy. Effective treatment of COVID-19 patients in the acute phase or of those with long COVID is a major challenge. Using data-independent acquisition (DIA) technology, we performed proteomic profiling on plasma samples from 22 COVID-19 patients and six healthy controls at Dazhou Central Hospital. Random forest and least absolute shrinkage and selection operator algorithms were used for analysis at various COVID-19 treatment stages. We identified 79 proteins that were differentially expressed between COVID-19 patients and healthy controls, mainly involving pathways associated with cell processes and binding. Across different treatment stages of COVID-19, five proteins-PI16, GPLD1, IGFBP3, KRT19, and VCAM1-were identified as potential molecular markers for dynamic disease monitoring. Furthermore, the proteins BTD, APOM, IGKV2-28, VWF, C4BPA, and C7 were identified as candidate biomarkers for distinguishing between SARS-CoV-2 positivity and negativity. Analysis of protein change profiles between the follow-up and healthy control groups highlighted cardiovascular changes as a concern for patients recovering from COVID-19. Our study revealed the infection profiles of SARS-CoV-2 at the protein expression level comparing different phases of COVID-19. DIA mass spectrometry analysis of plasma samples from COVID-19 patients undergoing treatment identified key proteins involved in signaling pathways that might be used as markers of the recovery phase. These findings provide insight for the development of therapy options and suggest potential blood biomarkers for COVID-19.

Risk factors in patients with acute fatty liver of pregnancy: the role of abortion, total bilirubin and serum creatinine.

PURPOSE: Acute fatty liver of pregnancy (AFLP) is a relatively rare obstetric emergency usually accompanied by fatal complications. Numerous studies have evaluated the potential risk factors for outcomes in patients with AFLP. But rare studies evaluated the predictive ability, sensitivity and specificity of the risk factors for maternal mortality. Thus, in this multicenter research, we aimed to further prove the predictive ability of the MELD model, investigated the prognostic value of history of abortion (HOA), total bilirubin (TBiL) and serum creatinine (SCr) and explored new predictive models for predicting maternal mortality in patients with AFLP. METHODS: We performed a retrospective cohort study of 133 hospitalised patients with AFLP in four Chinese tertiary hospitals between January 2009 and April 2014. RESULTS: The maximal AUC amongst three independent risk factors for maternal death was TBiL with a cut-off point of > 131.9 µmol/L, showing a sensitivity of 100% and a specificity of 55.9%. The threshold of the RF model for maternal mortality was - 1.629 and the AUC was 0.876, with an 81.8% sensitivity and an 80.2% specificity. The AUC for MELD model to predict maternal death was 0.894, and the best cut-off point was 28 with a sensitivity of 81.8% and a specificity of 84.7%. CONCLUSIONS: Both the MELD model and the RF model showed good efficacy in predicting the maternal mortality in patients with ALFP (AUC = 0.894 and 0.876, respectively).

Mechanism exploration of 6-Gingerol in the treatment of atherosclerosis based on network pharmacology, molecular docking and experimental validation.

BACKGROUND: The 6-Gingerol has significant anti-inflammatory, anti-oxidative and hypolipidemic activities and is widely used for treating cardiac-cerebral vascular diseases. However, the multi-target mechanism of 6-Gingerol in the treatment of atherosclerosis remains to be elucidated. METHODS: Firstly, the therapeutic actions of 6-Gingerol anti-atherosclerosis were researched based on an atherosclerotic ApoE-deficient mice model induced by high-fat feed. Then, network pharmacology and molecular docking were employed to reveal the anti-atherogenic mechanism of 6-Gingerol. Finally, the target for these predictions was validated by target protein expression assay in vitro and in vivo experiments and further correlation analysis. RESULTS: Firstly, 6-Gingerol possessed obvious anti-atherogenic activity, which was manifested by a significant reduction in the plaque area, decrease in the atherosclerosis index and vulnerability index. Secondly, based on network pharmacology, 14 predicted intersection target genes between the targets of 6-Gingerol and atherogenic-related targets were identified. The key core targets of 6-Gingerol anti-atherosclerosis were found to be TP53, RELA, BAX, BCL2, and CASP3. Lipid and atherosclerosis pathways might play a critical role in 6-Gingerol anti-atherosclerosis. Molecular docking results also further revealed that the 6-Gingerol bound well and stable to key core targets from network pharmacological predictions. Then, the experimental results in vivo and in vitro verified that the up-regulation of TP53, RELA, BAX, CASP3, and down-regulation of BCL2 from atherosclerotic ApoE-deficient mice model can be improved by 6-Gingerol intervention. Meanwhile, the correlation analysis further confirmed that 6-Gingerol anti-atherosclerosis was closely related to these targets. CONCLUSION: The 6-Gingerol can markedly improve atherosclerosis by modulating key multi-targets TP53, RELA, BAX, CASP3, and BCL2 in lipid and atherosclerosis pathways. These novel findings shed light on the anti-atherosclerosis mechanism of 6-Gingerol from the perspective of multiple targets and pathways.

Effects of Prone Positioning for Patients with Acute Respiratory Distress Syndrome Caused by Pulmonary Contusion: A Single-Center Retrospective Study.

Background: The effects of prone positioning (PP) on patients with acute respiratory distress syndrome (ARDS) caused by pulmonary contusion (PC) are unclear. We sought to determine the efficacy of PP among patients whose ARDS was caused by PC. Methods: A retrospective observational study was performed at an intensive care unit (ICU) from January 2017 to June 2021. ARDS patients with PaO2/FiO2 (P/F) < 150 mmHg were enrolled. During the study period, we enrolled 121 patients in the PP group and 117 in the control group. The changes in vital signs, laboratory tests, and compliance of the respiratory system (Crs) were recorded for 3 consecutive days. The mechanical ventilation time, duration of ICU stay, complications, extubation rate, 28-day ventilator-free days, and mortality were also recorded. Results: In the PP group, the P/F and Crs increased over time. Compared to the control group, the P/F and Crs improved in the PP group over 3 consecutive days (P < 0.05). Furthermore, the PP group also had shorter total mechanical ventilation time (5.1 ± 1.4 vs. 9.3 ± 3.1 days, P < 0.05) and invasive ventilation time (4.9 ± 1.2 vs. 8.7 ± 2.7 days, P < 0.05), shorter ICU stay (7.4 ± 1.8 vs. 11.5 ± 3.6days, P < 0.05), higher extubation rate (95.6% vs. 84.4%, P < 0.05), less atelectasis (15 vs. 74, P < 0.05) and pneumothorax (17 vs. 24, P > 0.05), more 28-day ventilator-free days (21.6 ± 5.2 vs. 16.2 ± 7.2 days, P < 0.05), and lower mortality (4.4% vs. 13.3%, P < 0.05). Conclusions: Among PC cases with moderate to severe ARDS, PP can correct hypoxemia more quickly, improve Crs, reduce atelectasis, increase the extubation rate, shorten mechanical ventilation time and length of ICU stay, and reduce mortality.

Actively implementing an evidence-based feeding guideline for critically ill patients (NEED): a multicenter, cluster-randomized, controlled trial.

BACKGROUND: Previous cluster-randomized controlled trials evaluating the impact of implementing evidence-based guidelines for nutrition therapy in critical illness do not consistently demonstrate patient benefits. A large-scale, sufficiently powered study is therefore warranted to ascertain the effects of guideline implementation on patient-centered outcomes. METHODS: We conducted a multicenter, cluster-randomized, parallel-controlled trial in intensive care units (ICUs) across China. We developed an evidence-based feeding guideline. ICUs randomly allocated to the guideline group formed a local "intervention team", which actively implemented the guideline using standardized educational materials, a graphical feeding protocol, and live online education outreach meetings conducted by members of the study management committee. ICUs assigned to the control group remained unaware of the guideline content. All ICUs enrolled patients who were expected to stay in the ICU longer than seven days. The primary outcome was all-cause mortality within 28 days of enrollment. RESULTS: Forty-eight ICUs were randomized to the guideline group and 49 to the control group. From March 2018 to July 2019, the guideline ICUs enrolled 1399 patients, and the control ICUs enrolled 1373 patients. Implementation of the guideline resulted in significantly earlier EN initiation (1.20 vs. 1.55 mean days to initiation of EN; difference - 0.40 [95% CI - 0.71 to - 0.09]; P = 0.01) and delayed PN initiation (1.29 vs. 0.80 mean days to start of PN; difference 1.06 [95% CI 0.44 to 1.67]; P = 0.001). There was no significant difference in 28-day mortality (14.2% vs. 15.2%; difference - 1.6% [95% CI - 4.3% to 1.2%]; P = 0.42) between groups. CONCLUSIONS: In this large-scale, multicenter trial, active implementation of an evidence-based feeding guideline reduced the time to commencement of EN and overall PN use but did not translate to a reduction in mortality from critical illness.

Epidemiology and Mortality of Sepsis in Intensive Care Units in Prefecture-Level Cities in Sichuan, China: A Prospective Multicenter Study.

BACKGROUND Studies on the epidemiology of sepsis in intensive care units (ICUs) of prefecture-level hospitals in China are rare. This study aimed to investigate the epidemiological characteristics and mortality risk factors of sepsis in ICUs of tertiary hospitals in Sichuan, China. MATERIAL AND METHODS In this prospective, multicenter, observational study, patients admitted to the ICU of 7 tertiary hospitals in Sichuan (China) between October 10, 2017 and January 9, 2018 were screened for sepsis using the Sepsis-3 criteria. Patients with sepsis were included. RESULTS Of the 1604 patients screened for sepsis, 294 (18.3%) had sepsis, and 140 (47.6%) had septic shock. Of these, 169 (57.5%) died. Multivariable analysis showed that central nervous system dysfunction (odds ratio [OR]=2.59, 95% confidence interval [CI]: 1.15-5.84, P=0.022), lowest blood phosphorus level (OR=2.56, 95% CI: 1.21-5.44, P=0.014), highest lactate level (OR=1.20, 95% CI: 1.10-1.32, P<0.001), 24-h Acute Physiologic Assessment and Chronic Health Evaluation-II (APACHE-II) score (OR=1.08, 95% CI: 1.03-1.13, P=0.002), and lung infection (OR=2.57, 95% CI: 1.30-5.09, P=0.007) were independently associated with mortality in patients with sepsis. CONCLUSIONS The prevalence and mortality rates of sepsis are high in tertiary hospital ICUs in Sichuan, China. The APACHE-II score on day 1 after diagnosis, acute central nervous system dysfunction, lowest blood phosphorus, high serum lactate, and lung infection were independent risk factors of mortality in patients with sepsis.

Early prone positioning therapy for patients with mild COVID-19 disease.

OBJECTIVE: In December 2019, Wuhan, China, experienced an outbreak of coronavirus disease 2019 (COVID-19). Some patients admitted to our hospital were treated with early prone positioning (PP). Here, we analyzed its clinical significance. METHODS: This was a retrospective observational study. We defined the early PP group as mild COVID-19 patients who were placed into a prone position within 24 h of admission; others served as the control group. We recorded basic data and outcomes of early PP and compared the results to those of controls. RESULTS: After 1 day of treatment, oxygenation was greater in the early PP group than in the control group (P/F: 421.6 ± 39.74 vs. 382.1 ± 38.84 mmHg [1 mmHg = 0.133 kPa], p < 0.01). And early PP group spent less total time in prone position (11.1 ± 4.17 vs. 16.9 ± 5.20 days, p < 0.01), and required shorter hospitalization duration (12.2 ± 4.49 vs. 23.2 ± 4.83 days, p < 0.001). CONCLUSIONS: Early PP treatment can improve hypoxia and shorten the prone position time and hospitalization duration in mild COVID-19 patients. It is a potential clinically applicable intervention.

OBJETIVO: En diciembre de 2019, Wuhan, China, experimentó un brote de enfermedad por coronavirus 2019 (COVID-19). Algunos pacientes ingresados en nuestro hospital fueron tratados con posicionamiento temprano en decúbito prono (PP). En este estudio analizamos su significación clínica. MÉTODOS: Estudio retrospectivo observacional en el que definimos el PP temprano como aquellos pacientes con COVID-19 que fueron posicionados en decúbito prono dentro de las 24 horas siguientes a su ingreso, sirviendo el resto de los pacientes como grupo control. Registramos los datos básicos y los resultados de PP temprano, comparando dichos resultados con los de los controles. RESULTADOS: Tras un día de tratamiento, la oxigenación fue más alta en el grupo PP temprano que en el grupo control (P/F: 421,6 ± 39,74 vs. 382,1 ± 38,84 mmHg [1 mmHg = 0,133 kPa], p < 0,01). El grupo PP temprano pasó menor tiempo total en posición de decúbito prono (11,1 ± 4,17 vs. 16,9 ± 5,20 días, p < 0,01), y requirió menor tiempo de hospitalización (12,2 ± 4,49 vs. 23,2 ± 4,83 días, p < 0,001). CONCLUSIONES: El tratamiento de PP temprano puede mejorar la hipoxia y reducir el tiempo de posición en decúbito prono en pacientes con COVID-19 leve. Se trata de una intervención potencialmente aplicable desde el punto de vista clínico.

Hepatic portal venous gas: A case report and analysis of 131 patients using PUBMED and MEDLINE database.

OBJECTIVE: Hepatic portal pneumatosis has a high mortality rate, and whether surgical intervention is necessary remains controversial. This experiment retrospectively analyzed the etiology, treatment methods and prognosis of adult patients with hepatoportal pneumocele to provide a theoretical basis for the treatment of this disease. METHODS: We analyzed the clinical symptoms and post-treatment of a 43-year-old male patient with HPVG admitted to hospital. We retrieved adult non-iatrogenic HPVG cases with complete clinical data in PUBMED,  and MEDLINE and other databases were retrieved for analysis, and summarized the pathogenesis, clinical symptoms, pathogenesis, pathogenesis and prognosis of different treatment schemes were summarized. RESULTS: The main etiology of HPVG are intestinal ischemia (27%), severe enteritis/intestinal perforation/intestinal fistula (16%), intestinal obstruction (7%), abdominal infection (7%), gastric diseases (11%), appendicitis and its complications (5%), acute hemorrhage or necrotizing pancreatitis (5%), Crohn's disease and its complications (4%), trauma (traffic accidents, falls) (2%), diverticulitis and perforation (6%), nephrogenic diseases (4%), spontaneous pneumohepatic portal vein (2%), other reasons (4%). And after analysis, we found that the survival rate of patients treated by surgery was 40.5% and the mortality rate was 19.1%, the difference between the two was significant. CONCLUSIONS: Etiology should be actively explored and surgical treatment is necessary.

Clinical features and multidisciplinary treatment outcome of COVID-19 pneumonia: A report of three cases.

The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic threatening global public health. In the current paper, we describe our successful treatment of three COVID-19 pneumonia patients cases including severe cases and cases with mortality risk factors. One 32-year-old male COVID-19 patient was diagnosed with severe COVID-19 pneumonia and moderate ARDS. The second COVID-19 pneumonia patient had a history of diabetes and chronic bronchitis. The third case of COVID-19 pneumonia was an 82-year old female patient. All three cases had severe COVID pneumonia and therefore were aggressively managed with a multidisciplinary and personalized therapeutic approach that included nutritional support, antiviral pharmacotherapy, active control of comorbidities, prevention of complication development and psychological intervention. Our experience highlights the importance of the use of a multidisciplinary therapeutic approach that tailors to the specific condition of the patient in achieving a favorable clinical outcome.

Enteral nutrition feeding in Chinese intensive care units: a cross-sectional study involving 116 hospitals.

BACKGROUND: There is a lack of large-scale epidemiological data on the clinical practice of enteral nutrition (EN) feeding in China. This study aimed to provide such data on Chinese hospitals and to investigate factors associated with EN delivery. METHODS: This cross-sectional study was launched in 118 intensive care units (ICUs) of 116 mainland hospitals and conducted on April 26, 2017. At 00:00 on April 26, all patients in these ICUs were included. Demographic and clinical variables of patients on April 25 were obtained. The dates of hospitalization, ICU admission and nutrition initiation were reviewed. The outcome status 28 days after the day of investigation was obtained. RESULTS: A total of 1953 patients were included for analysis, including 1483 survivors and 312 nonsurvivors. The median study day was day 7 (IQR 2-19 days) after ICU entry. The proportions of subjects starting EN within 24, 48 and 72 h after ICU entry was 24.8% (84/352), 32.7% (150/459) and 40.0% (200/541), respectively. The proportion of subjects receiving > 80% estimated energy target within 24, 48, 72 h and 7 days after ICU entry was 10.5% (37/352), 10.9% (50/459), 11.8% (64/541) and 17.8% (162/910), respectively. Using acute gastrointestinal injury (AGI) 1 as the reference in a Cox model, patients with AGI 2-3 were associated with reduced likelihood of EN initiation (HR 0.46, 95% CI 0.353-0.599; p < 0.001). AGI 4 was significantly associated with lower hazard of EN administration (HR 0.056; 95% CI 0.008-0.398; p = 0.004). In a linear regression model, greater Sequential Organ Failure Assessment scores (coefficient - 0.002, 95% CI - 0.008 to - 0.001; p = 0.024) and male gender (coefficient - 0.144, 95% CI - 0.203 to - 0.085; p < 0.001) were found to be associated with lower EN proportion. As compared with AGI 1, AGI 2-3 was associated with lower EN proportion (coefficient - 0.206, 95% CI - 0.273 to - 0.139; p < 0.001). CONCLUSIONS: The study showed that EN delivery was suboptimal in Chinese ICUs. More attention should be paid to EN use in the early days after ICU admission.
