Prevalence and impact of viral myocarditis in patients with severe fever with thrombocytopenia syndrome.

To explore the association and impact between viral myocarditis and mortality in patients with severe fever with thrombocytopenia syndrome. A dynamic analysis was conducted between fatal group and nonfatal group regarding the daily epidemiology data, clinical symptoms, and electrocardiogram (ECG), echocardiogram, and laboratory findings. Outcomes of patients with and without viral myocarditis were compared. The association between viral myocarditis and mortality was analyzed. Among 183 severe fever with thrombocytopenia syndrome patients, 32 were in the fatal group and 151 in the nonfatal group; there were 26 (81.25%) with viral myocarditis in the fatal group, 66 (43.70%) with viral myocarditis in the nonfatal group (p < 0.001), 79.35% of patients had abnormal ECG results. The abnormal rate of ECG in the fatal group was 100%, and in the nonfatal group was 74.83%. Univariate analysis found that the number of risk factors gradually increased on Day 7 of the disease course and reached the peak on Day 10. Combined with the dynamic analysis of the disease course, alanine aminotransferase, aspartate aminotransferase, creatine kinase, creatine kinase fraction, lactate dehydrogenase, hydroxybutyrate dehydrogenase, neutrophil count, serum creatinine, Na, Ca, carbon dioxide combining power, amylase, lipase, activated partial thromboplastin time and thrombin time had statistically significant impact on prognosis. The incidence of fever with thrombocytopenia syndrome combined with viral myocarditis is high, especially in the fatal group of patients. Viral myocarditis is closely related to prognosis and is an early risk factor. The time point for changes in myocarditis is Day 7 of the course of the disease.

Dual-targeting tigecycline nanoparticles for treating intracranial infections caused by multidrug-resistant Acinetobacter baumannii.

Multidrug-resistant (MDR) Acinetobacter baumannii (A. baumannii) is a formidable pathogen responsible for severe intracranial infections post-craniotomy, exhibiting a mortality rate as high as 71%. Tigecycline (TGC), a broad-spectrum antibiotic, emerged as a potential therapeutic agent for MDR A. baumannii infections. Nonetheless, its clinical application was hindered by a short in vivo half-life and limited permeability through the blood-brain barrier (BBB). In this study, we prepared a novel core-shell nanoparticle encapsulating water-soluble tigecycline using a blend of mPEG-PLGA and PLGA materials. This nanoparticle, modified with a dual-targeting peptide Aß11 and Tween 80 (Aß11/T80@CSs), was specifically designed to enhance the delivery of tigecycline to the brain for treating A. baumannii-induced intracranial infections. Our findings demonstrated that Aß11/T80@CSs nanocarriers successfully traversed the BBB and effectively delivered TGC into the cerebrospinal fluid (CSF), leading to a significant therapeutic response in a model of MDR A. baumannii intracranial infection. This study offers initial evidence and a platform for the application of brain-targeted nanocarrier delivery systems, showcasing their potential in administering water-soluble anti-infection drugs for intracranial infection treatments, and suggesting promising avenues for clinical translation.

The Clinical Efficacy Evaluation of Thigh Liposuction Based on 3-Dimensional Digital Technology: A Quantitative Study.

BACKGROUND: There is a lack of convenient and accurate objective methods to evaluate the clinical efficacy of thigh liposuction. METHODS: This retrospective study involved the 3-dimensional images of 19 patients who underwent bilateral thigh liposuction. Data such as volume change and volume change rate before and after surgery, circumference change, and circumference change rate of 3 planes (upper, middle, and lower) were analyzed. The correlation between body mass index and volume change rate and between preoperative circumference and circumference change rate of different planes were determined. RESULTS: There were significant differences between the preoperative and postoperative volume and circumference of 3 planes of 19 patients (38 thighs). The rate of change in total volume (16.90 ± 5.55%) correlated with the circumference change rate at the top of the thigh. There was also a linear relationship between body mass index and volume change rate, but not between preoperative circumference and circumference change rate. CONCLUSIONS: Three-dimensional imaging technology can accurately quantify the volume and circumference change of the thigh to objectively evaluate the clinical efficacy of thigh liposuction.

Risk factors and potential predictors of pulmonary embolism in cancer patients undergoing thoracic and abdominopelvic surgery: a case control study.

BACKGROUND: Postoperative pulmonary embolism (PE) is a severe complication leading to death and poor prognosis. The present study investigated the risk factors and potential predictors of PE in cancer patients undergoing thoracic and abdominopelvic surgery. METHODS: A retrospective study was conducted on the patients with cancer who underwent thoracic and abdominopelvic surgery in Sichuan Cancer Hospital from December 2016 to January 2022. A total of 189 patients were included, in which 63 patients diagnosed PE after operation were collected as PE group, and 126 patients matched by age, type of cancer and cancer location were enrolled as control group. Conditional logistic regression was conducted to analyze the association between PE and risk factors. Predictive values of key factors were compared by the area under the curve (AUC) in receiver operating characteristic curve (ROC) curve. RESULTS: Conditional multivariate logistic regression showed that BMI (odds ratio [OR] 4.065, 95% confidence interval [CI] 1.138-14.527; p = 0.031), intraoperative hypotension time (OR 4.095, 95% CI 1.367-12.266; p = 0.009), same day fluid balance (OR 0.245, 95% CI 0.061-0.684; p = 0.048), and postoperative D-Dimer (OR 1.693, 95% CI 1.098-2.611; p = 0.017) were significantly related to the occurrence of postoperative PE. Postoperative D-Dimer had the maximal AUC value 0.8014 (95% CI: 0.7260-0.8770) for predicting PE, with a cutoff value of 1.505 µg/ml. CONCLUSIONS: BMI, intraoperative hypotension time, lower same day fluid balance and postoperative D-dimer are independent risk factors associated with PE in cancer patients undergoing thoracic and abdominopelvic surgery. Postoperative D-Dimer seems to be a good indicator to predict postoperative PE for cancer patients.

Impact on Short-Term Complications of Early Oral Feeding in Patients with Esophageal Cancer After Esophagectomy.

To evaluate early oral feeding (EOF) in short-term outcomes of patients with esophageal cancer after esophagectomy. 179 patients with esophageal cancer who underwent esophagectomy between January 2016 and February 2018 were enrolled for this study. 87 patients with EOF without nasogastric tube or nasogastric tube was removed within 24 h, were selected as the experimental group, whereas 92 patients who received nasojejunal tube feeding were set as the control group. All laboratory testing, clinical features, and hospitalization expenses were compared between the two groups. No statistical significance was observed between the two groups in hemoglobin, albumin, and prealbumin levels after esophagectomy. Notably, there was no significant difference in the incidence of severe pneumonia and anastomotic leakage between the two groups. Admittance period, postoperative defecation time, and medical expenses were significantly decreased among patients with EOF (P < 0.001). Multivariate Cox multiple-factor regression analysis revealed that there was no correlation between EOF and the risk of anastomotic leakage. EOF might not be a risk factor for increasing the incidence of severe pneumonia and anastomotic leakage in patients with esophageal cancer after esophagectomy, and it could reduce the hospitalization period as well as control medical expenses.

Volume Retention After Facial Fat Grafting and Relevant Factors: A Systematic Review and Meta-analysis.

BACKGROUND: Autologous fat grafting is common in facial reconstructive and cosmetic surgeries; the most important drawbacks are the high absorption rate and unpredictable volume retention rate. Surgeons usually make clinical judgements based on their own experience. Therefore, this study aimed to systematically and quantitatively review the volume retention rate of facial autologous fat grafting and analyse the relevant influencing factors. METHODS: A systematic literature review was performed using the Medline, EMBASE, Cochrane Library, and Web of Science databases in October 2019 for articles that reported objectively measured volume retention rates of facial fat grafting. Patient characteristics, fat graft volumetric data, and complications were collected. A meta-analysis using a random-effects model was conducted to pool the estimated fat retention rate. Relevant factors were analysed and reviewed on the basis of subgroups. RESULTS: We included 27 studies involving 1011 patients with facial fat grafting. The volume retention rate varied from 26 to 83%, with a mean follow-up of 3-24 months. The overall pooled retention rate was 47% (95% CI 41-53%). The volume measurement method significantly influenced the reported retention rate. A trend towards better retention was found for secondary fat grafting procedures and patients with congenital deformities. Only 2.8% of all patients had complications. CONCLUSION: The exact percentage of facial fat grafts retained is currently unpredictable; the reported rate varies with different estimation methods. This review analysed studies that provided objectively measured volume retention rates, the pooled average percentage of facial fat graft retention (47%, 95% CI 41-53%), and relevant factors.

Application of a Proposed Multi-Positional Circumferential Arm Liposuction Method and Quantification of its Clinical Efficacy Evaluation.

BACKGROUND: Upper arm liposuction mainly focuses on the posterolateral region, which may lead to a lack of harmony between the aspirated and unaspirated areas. In addition, the treatment effect of arm liposuction is often evaluated only by preoperative and postoperative photograph comparison and simple measurement; quantitative research on this topic is still lacking. METHODS: The multi-positional circumferential arm liposuction (MCAL) technique was proposed and applied to a total of 34 females in our hospital from 2017 to 2019. Three-dimensional data of 12 patients before the operation and after 2-3 months were collected and processed by 3D imaging, and the volume reduction rate was evaluated quantitatively. RESULTS: The MCAL method was successfully applied in the clinic, and its surgical effect was quantitatively studied. The mean follow-up time of 12 patients was (75.2 ±13.1) days, and the postoperative volume was significantly reduced. The postoperative volume of patients with type I, type II and type III decreased by (10.79 ±2.55)%, (17.25 ±3.02)% and (22.76 ±3.51)%, respectively. CONCLUSION: Our new MCAL technique was successful, maximizing the esthetic results in upper limb contour refinements in the superficial fascial layer. The clinical efficacy of this proposed MCAL method was evaluated by CT and 3D digital technology, which provided further accuracy in demonstrating its effect on the shape of the arm.

Transbrow Excision Blepharoplasty for Upper Eyelid Dermatochalasis: A Modified Approach.

BACKGROUNDS: Many aging women with upper lid dermatochalasis pluck their lower lateral eyebrows to combat lateral drooping. The authors present and evaluate outcomes of a modified excision blepharoplasty method performed using a transbrow excision approach instead of infra/suprabrow access to more efficiently correct upper eyelid dermatochalasis. METHODS: The authors conducted a retrospective review of 192 patients who underwent transbrow excision blepharoplasty (TBEB) between 2014 and 2019 at the Plastic Surgery Hospital of Beijing in China. The clinical features, complications, and outcomes of patients were reviewed. The Strasser grading system was used to evaluate surgical results postoperatively. Aesthetic improvement was subjectively judged by the patients. RESULTS: All 192 patients (aged 25-72 years old, mean 46 years old) were reviewed and followed up for 6 months to 2 years. Patients were evaluated after 1 week and after at least 6 months. All patients reported an improved aesthetic appearance of the lateral periorbital area, and 174 patients (90.6%) rated their results as satisfactory. No serious complications were related to the procedure. CONCLUSIONS: TBEB is used to correct problems that are not adequately managed by conventional excision blepharoplasty. Among 192 patients evaluated over 5 years, excision of the transbrow skin pad sufficiently reduced the redundancy of the upper eyelid and achieved an acceptable appearance of the periorbital area, where the postoperative location of a subtle scar defined a desired youthful brow position. In selected patients, this is an effective and safe method that uses patient-observed features to provide an alternate cosmetic approach.

Enhanced antifungal activity of bovine lactoferrin-producing probiotic Lactobacillus casei in the murine model of vulvovaginal candidiasis.

BACKGROUND: Vulvovaginal candidiasis (VVC) is a common vaginitis caused by Candida species,a frequently recurring condition. Fungal azole-resistant strains with azole-resistance have developed for long and wide explosion to the first-line antifungal azole agent. Bovine lactoferrin (BLF) is a protein from transferrin family secreted by the bovine mammary tissue. Its various biological functions are well known, especially the pronounced antifungal activity. RESULTS: In the current study, we constructed a Lactobacillus casei strain (L.casei/pPG612.1-BLF), which secreted BLF encoded by a mature secretion vector plasmid pPG612.1, and evaluated its antifungal activity in vitro and in vivo. In a two-layer agar plate in vitro assay, the number of C. albicans CFUs decreased and the average colony size shrunk upon exposure to L. casei/pPG612.1-BLF. In a murine VVC model, the infection burden of mice intra-vaginally pre-inoculated with L. casei/pPG612.1-BLF was lower than in control groups. Furthermore, the infection burden in mice with VVC was reduced when the animals were continually given L. casei/pPG612.1-BLF as a topical treatment for 5 days. CONCLUSION: Combined, these results suggested that the L. casei/pPG612.1-BLF strain is a promising preventative and therapeutic anti-VVC agent, highlighting the possibility of employing the probiotic L. casei as a vehicle for biotherapy in the female genital tract and exploiting the natural antibiotic antimicrobial peptides for other applications.

Tumor suppressor miR-128-3p inhibits metastasis and epithelial-mesenchymal transition by targeting ZEB1 in esophageal squamous-cell cancer.

MicroRNAs (miRNAs) are some short RNAs that regulate multiple biological functions at post-transcriptional levels, such as tumorigenic processes, inflammatory lesions and cell apoptosis. Zinc finger E-box binding homeobox factor 1 (ZEB1) is a crucial mediator of epithelial-mesenchymal transition (EMT). It induces malignant progression of various cancers including human esophageal squamous-cell carcinoma (ESCC). In this study, we found that miR-128-3p was downregulated in ESCC tissues and cells by using PCR. Moreover, down-regulated expression of miR-128-3p was testified to be associated with poor prognosis of ESCC patients and might be regarded as an independent prognostic factor. Then, we examined the role of miR-128-3p in ESCC cells, and found that miR-128-3p could suppress the cell migration and invasion in vitro. Furthermore, ZEB1 was confirmed to be a direct target of miR-128-3p by luciferase reporter assay. Rescue experiments proved that EMT was regulated by miR-128-3p via suppression of ZEB1. Taken all together, we conclude that miR-128-3p suppresses EMT and metastasis via ZEB1, and miR-128-3p may be a critical mediator in ESCC.

[Analysis of DYSF gene mutations in two pedigrees affected with limb-girdle muscular dystrophy type 2B].

OBJECTIVE: To analyze mutations of DYSF gene in two pedigrees affected with limb-girdle muscular dystrophy 2B (LGMD-2B). METHODS: Genomic DNA was extracted from peripheral blood samples of the two probands and unaffected family members. Variant sites were screened by next-generation sequencing using gene panel as well as Sanger sequencing. RESULTS: Four pathogenic mutations of the DYSF gene were detected, which included a de novo mutation and three mutations with uncertain significance. In pedigree 1, the proband carried compound heterozygous mutations of c.1667T to C (p.Leu556Pro) and c.5567T to A (p.Val1856Glu), which were respectively inherited from her mother and father. Proband of pedigree 2 carried compound heterozygous mutations of c.4853A to G (p.Tyr1618Cys) and c.4876G to A (p.Val1612Ile), among which c.4876G to A (p.Val1626Ile) was also found in his father and grandfather, while c.4853A to G (p.Tyr1618Cys) was detected in his mother and grandmother. CONCLUSION: The two compound heterozygous mutations of the DYSF gene probably underlie the LGMD2B in the two pedigrees. Next generation sequencing has conferred great advantage for gene diagnosis of hereditary myopathy.

Evaluation of Repairing Facial Depression Deformities Secondary to Lupus Erythematosus Panniculitis With Autologous Fat Grafting.

BACKGROUND: A facial depression deformity secondary to lupus erythematosus panniculitis results from fat necrosis, which seriously alters the patients' appearance and thus affects their psychological health. Few studies have discussed the repair of depression deformities. The authors repaired depression deformities due to atrophic lesions by using autologous fat grafting to obtain volumetric restoration of the facial skin, and the authors report our outcomes. METHODS: In this series, 30 depression deformities in 18 patients were repaired. The authors suctioned fat grafts from the abdomen and centrifuged them at 500×g for 2 minutes. After discarding the upper oil and bottom liquid, the middle fat was injected into the depressed areas (ie, the cheek, temple, and zygoma) by using multiplane and multitunnel injections. The patients, plastic surgeons on staff, and laypersons evaluated the cosmetic outcome of each patient. RESULTS: No infection, subcutaneous nodules or cysts, cutaneous necrosis, blood vessel embolism, or other complications were found in any patient. Five patients had 1 injection, 5 had 2 injections, and 8 had 3 injections. All depression deformities improved. Regarding the cosmetic outcome, 33.3% of patients, 27.8% of laypersons, and 38.9% of doctors were satisfied with the results; 44.4% of patients, 55.6% of laypersons, and 50.0% of doctors were mostly satisfied. CONCLUSION: Autologous fat grafting can be a good choice for repairing facial depression deformities in patients with lupus erythematosus panniculitis, although 1 or more subsequent injections may be required to maintain the improved outcome.

Clinical curative effect of Mesalt combined with Mepilex dressing in postoperative infection of inguinal hernia.

BACKGROUND: Inguinal hernia is a common surgical disease. Tension-free hernioplasty is currently commonly used for its treatment, with multiple advantages such as simple surgical method, low recurrence rate, and ability to be performed in primary care hospitals, but the risk of incision infection still exists. Mild infection can be cured by local washing, dressing, and systemic antibiotics. If the infection is severe, the wound may not heal after removing the patch, and secondary suturing is needed. MATERIAL AND METHODS: A total of 60 patients with postoperative infection after tension-free repair of inguinal hernia were randomly divided into control (n=30) and treatment (n=30) groups. Patients in the treatment group received Mesalt combined with Mepilex for dressing while the patients in the control group received conventional gauze for dressing. Pain degree, wound healing time, and dressing times were observed. RESULTS: The clinical therapeutic effect in the treatment group was significantly better than in the control group. The treatment group exhibited significantly less pain when patients receive dressing, shorter wounds healing time (15 ± 3.5 vs. 30 ± 5.0), and less dressing frequency (10 ± 2.1 vs. 20 ± 2.4). CONCLUSIONS: Mesalt combined with Mepilex can effectively improve postoperative infection after inguinal hernia treatment, obviously reducing pain, shorting wound healing time, and decreasing dressing frequency. It can be widely used in clinical practice.

Therapeutic effects of mesenchymal stem cell-derived microvesicles on pulmonary arterial hypertension in rats.

AIM: Microvesicles (MVs) are nanoscale membrane fragments released from virtually all cell types upon activation or apoptosis, and may contribute to the beneficial effects of stem cell therapy. In this study, we investigated the therapeutic effects of mesenchymal stem cell (MSC) derived MVs (MSC-MVs) on pulmonary artery hypertension (PAH) in rats. METHODS: MSC-MVs were isolated from rat bone marrow MSCs that were cultured in a serum-free conditioned medium. Transmission electron microscopy (TEM), flow cytometry and nanoparticle tracking analysis (NTA) were used to characterize the MVs. Adult SD rats were injected with monocrotaline (50 mg/kg, sc) to induce PAH. Three weeks later, the rats were intravenously injected with MSCs, MSC-MVs or saline for 2 weeks. At the end of treatments, the hemodynamic parameters and pathological right ventricular and pulmonary arterial remodeling were analyzed in each group. RESULTS: The MSC-MVs showed general morphologic characteristics of MVs and expressed annexin V and CD29 markers under TEM, and their size ranged from 40 to 300 nm. Intravenous injection of MSC-MVs or MSCs significantly ameliorated the mean pulmonary artery pressure (mPAP) and mean right ventricle pressure (mRVP) in PAH rats. Furthermore, intravenous injection of MSC-MVs or MSCs significantly decreased the right ventricle (RV) hypertrophy and pulmonary arteriole area index (AI) and thickness index (TI) in PAH rats. CONCLUSION: Intravenous injection of MSC-MVs or MSCs produces similar beneficial effects for treating PAH, and our results provide a basis for cell-free approach in stem cell therapy.

[Hepatocyte growth factor intervention on rats with pulmonary hypertension and effect of endothelial cell membrane microparticles].

OBJECTIVE: To explore the effect of transfection of adenovirus carrying hepatocyte growth factor (HGF) on pulmonary arterial hypertension (PAH) and endothelial cell membrane microparticles (EMP) in a rat model, and the underlying mechanism. METHODS: Forty healthy male SD rats were randomly divided into four groups, the normal control group (NOR group), monocrotaline (MCT)-induced pulmonary hypertension group (PAH group), HGF treatment of PAH group (HGF group and THGF group) each with 10 rats. NOR group and the PAH Group: intratracheal instillation of 0.2 ml PBS solution; HGF group: intratracheal instillation of 0.2 ml HGF one times; THGF Group: intratracheal instillation of 0.2 ml HGF one times, and then 1 week repeat again. Different interventions after 2 weeks, the rats was measured mean pulmonary arterial pressure, right ventricular hypertrophy index calculation, HE staining index of pulmonary arterial wall thickness, area index, plasma levels of endothelial cell microparticles. RESULTS: HGF intratracheal instillation after 2 weeks, HGF and THGF groups of SD rats mPAP, RVHI, TI, AI decreased significantly compared with PAH group (P < 0.05). PAH group was increased in particulate levels at different time points significantly higher levels of horizontal (P < 0.05). The EMP levels in HGF group which at 7 and 14 days after dosing were significantly decreased compared with PAH.It still higher than the NOR group (P < 0.05). And after administration of 7 days, 14 days, the EMP level of HGF group was significantly lower than before administration (P < 0.05). CONCLUSIONS: Thought airway instillation transfected HGF, pulmonary artery pressure can reduce greater degree, but can't achieve complete reversal. It can inhibit the pulmonary artery wall thickening and maintain effective lumen area, delaying the right ventricular hypertrophy by reducing the membrane particles within the lung, thereby promoting endothelial cell repair to achieve the goal of intervention in pulmonary hypertension.

The results of meta-analysis showed: Relapse-free survival [hazard ratio (HR) = 2.66, 95% confidence interval (CI): 2.30-3.08; P < 0.00001], disease-free survival (HR = 3.68, 95%CI: 2.33-5.81; P < 0.00001) and overall survival (HR = 1.70, 95%CI: 1.53-1.87; P < 0.00001) were significantly lower than those in mature group (control group); relapse-free survival (HR = 1.36, 95%CI: 1.17-1.59; P < 0.0001) and disease-free survival rate (HR = 1.85, 95%CI: 1.53-2.24; P < 0.0001) was significantly lower than the mature group (control group). CONCLUSION: There is the correlation between tumor interstitial maturity and survival prognosis of colorectal cancer, and different degrees of tumor interstitial maturity have a certain impact on the quality of life of colorectal cancer patients.

Oscillatory rheometry for elucidating the influence of non-network biopolymer aggregation on pectin-gelatin composite gels.

Gel networks formed from biopolymers have intrigued rheological interest, especially in the food industry. Despite ubiquitous non-network biopolymer aggregation in real gel food systems, its fundamental rheological implications remain less understood. This study addresses this by preparing pectin-gelatin composite gels with dispersed or aggregated biopolymers and comparatively analyzing viscoelastic responses using rheometry. Subtle discrepancies in non-network biopolymer states were revealed through oscillatory shearing at different frequencies and amplitudes. Biopolymer aggregation in the network notably influenced loss tangent frequency dependency, particularly at high frequencies, elevating I3/I1 values and sensitizing the yield point. Non-network biopolymers weakened Payne effects and gel non-linearity. A combination of strain stiffening and shear thinning nonlinear responses characterized prepared gel systems. Aggregation of pectin and gelatin enhanced shear thinning, while strain stiffening was notable in highly aggregated pectin cases. This study enhances understanding of the link between non-network structural complexity and viscoelastic properties in oscillatory rheometry of food gels.

Hypomagnesemia Is Associated with the Acute Kidney Injury in Traumatic Brain Injury Patients: A Pilot Study.

BACKGROUND: Acute kidney injury (AKI) commonly develops among traumatic brain injury (TBI) patients and causes poorer outcomes. We perform this study to explore the relationship between serum magnesium and the risk of AKI among TBI. METHODS: TBI patients recorded in the Medical Information Mart for Intensive Care-III database were eligible for this research. The restricted cubic spline (RCS) was utilized to fit the correlation between serum magnesium level and the AKI. Univariate and subsequent multivariate logistic regression analysis were utilized to explore risk factors of AKI and confirmed the correlation between serum magnesium and AKI. RESULTS: The incidence of AKI in included TBI was 21.0%. The RCS showed that the correlation between magnesium level and risk of AKI was U-shaped. Compared with patients whose magnesium level was between 1.5 and 2.0 mg/dL, those with a magnesium level of <1.5 mg/dL or >2.0 mg/dL had a higher incidence of AKI. Multivariate logistic regression confirmed age, chronic renal disease, ISS, serum creatinine, vasopressor, mechanical ventilation, and serum magnesium <1.5 mg/dL were independently related with the AKI in TBI. CONCLUSION: Abnormal low serum magnesium level is correlated with AKI development in TBI patients. Physicians should pay attention on renal function of TBI patients especially those with hypomagnesemia.

Association and predictive value of soluble thrombomodulin with mortality in patients with acute respiratory distress syndrome: systematic review and meta-analysis.

Background: Acute respiratory distress syndrome (ARDS) is a heterogeneous illness that has a high mortality rate. The role and predictive value of soluble thrombomodulin (sTM) in ARDS mortality is disputable, so the present study aimed to evaluate the association and predictive value of sTM for the in-hospital mortality of ARDS. Methods: PubMed, Web of Science, Embase, Cochrane Library, Chongqing VIP, WanFang, China National Knowledge Infrastructure (CNKI), and Chinese Biomedical Literature databases were searched for relevant literature published before October 10, 2022. Relevant observable studies were included for analysis. The Newcastle-Ottawa Scale and QUAPAS (Quality Assessment of Prognostic Accuracy Studies) were employed to appraise the quality of the included studies. Results: Thirteen articles were included in the present study. The eligible studies were of moderate to high quality [Newcastle-Ottawa Scale (NOS) 5-8 scores], and the high risk of bias in the included studieson predictive value was mainly distributed in participant and analysis domains of QUAPAS. There were 1,992 patients with ARDS, and 538 died. Our meta-analysis demonstrated that nonsurvivors had more significantly increased sTM levels than did survivors [standardized mean difference (SMD) =1.473; 95% CI: 0.874-2.072; P<0.001]. Elevated sTM levels had an independent correlation with higher mortality in patients with ARDS [pooled odds ratio (OR) =2.126; 95% CI: 1.548-2.920; P<0.001]. sTM showed satisfactory performance in predicting the mortality of ARDS [summary receiver operating characteristic curve (SROC) =0.78; 95% CI: 0.64-0.89]. The pooled sensitivity was 72% (95% CI: 66-77%), and the pooled specificity was 77% (95% CI: 72-82%). Subgroup analysis showed no significant difference in the sTM levels between nonsurvivors and survivors in terms of patients with direct ARDS (SMD =0.813; 95% CI: -0.673 to 2.229; P=0.253). Conclusions: sTM is associated with hospital mortality in ARDS and shows moderate predictive performance. As a result, it is a potential candidate for predicting the mortality of ARDS. However, caution is needed when sTM is used to predict adverse outcomes in patients with direct ARDS.

Facile post-gelation soaking strategy toward low-alkaline konjac glucomannan gels.

A facile post-gelation soaking strategy for producing low-alkaline konjac glucomannan (KGM) gels was investigated in this work. The dealkalization kinetics of soaking alkali-induced gels in citric acid (CA) solutions was determined. A comparison of sensory, textural, and water holding properties was made between untreated and post-soaking gels. Post-gelation exposure to acid took less time for lowering the gel pH at higher CA concentrations, eliminated the unattractive flavor of KGM gels and endowed them a higher hardness and breaking force. Comparatively, the whiteness of post-soaking gels was increased by 3.8%-13.1% with volume being decreased by 4.9%-8.6%, while the discrepancies were less apparent after a long-term storage. Low-alkaline gels treated by 4 g/L CA shared similar textural features with conventional KGM gels. Despite the difference in water distribution and water holding capacity of KGM gels, the syneresis of resultant low-alkaline KGM gels was not significantly affected.
