Objective. To systematically review the efficacy and potential immunomodulatory effect of ulinastatin combined with thymosinα1 (UTI) for sepsis.Design. A systematic review and meta-analysis of randomized controlled trials (RCTs).Data Sources. The following databases: PubMed, Embase, and Cochrane Central were searched to identify related clinical trials. The search terms were “ulinastatin”, “thymosin”, and “sepsis”.Results. Six RCTs, 944 septic patients in total, were included in this meta-analysis. The result shows UTI increased the 28-day survival rate of septic patients, odds ratio (OR) = 2.01, 95% CI [1.53, 2.64]. After the treatment with UTI, the APACHE II score (four studies) dropped 4.72 further, mean = −4.72, 95% CI [−6.54, −2.91] (p<0.00001). The mean time of ICU stay (four studies) in UTI group decreased 3.03 days further, mean = −3.03 [−6.99, 0.95] (p=0.14), and mechanical ventilation time (four studies) decreased 2.05 days, mean = −1.81 [−2.96, −0.66] (p=0.002). With the treatment of UTI, CD4+T cells raised 5.13%, mean = 5.13, 95% CI [2.75, 7.50] (p<0.0001); there was no significant change in CD8+T cells, mean = −0.74 [−2.93, 1.45] (p=0.51).Conclusion. According to this meta-analysis, with the treatment of UTI, the short-term survival rate of septic patients was increased and the illness severity was alleviated. ICU stay and mechanical ventilation time were effectively shortened. The beneficial effect of UTI might be due to the potential immunomodulatory effects of these two drugs.

Abstract Introduction Ventilator-associated pneumonia (VAP) is reported as the second most common nosocomial infection among critically ill patients with the incidence ranging from 2 to 16 episodes per 1000 ventilator days. The use of probiotics has been shown to have a promising effect in many RCTs. Our systematic review and meta-analysis were thus planned to determine the effect of probiotic use in critically ill ventilated adult patients on the incidence of VAP, length of hospital stay, length of ICU stay, duration of mechanical ventilation, the incidence of diarrhea, and the incidence of oropharyngeal colonization and in-hospital mortality. Methodology Systematic search of various databases (such as Embase, Cochrane, and Pubmed), published journals, clinical trials, and abstracts of the various major conferences were made to obtain the RCTs which compare probiotics with placebo for VAP prevention. The results were expressed as risk ratios or mean differences. Data synthesis was done using statistical software - Review Manager (RevMan) Version 5.4 (The Cochrane Collaboration, 2020). Results Nine studies met our inclusion criterion and were included in the meta-analysis. The incidence of VAP (risk ratio: 0.70, CI 0.56, 0.88; P = 0.002; I2 = 37%), duration of mechanical ventilation (mean difference −3.75, CI −6.93, −0.58; P 0.02; I2 = 96%), length of ICU stay (mean difference −4.20, CI −6.73, −1.66; P = 0.001; I2 = 84%) and in-hospital mortality (OR 0.73, CI 0.54, 0.98; P = 0.04; I2 = 0%) in the probiotic group was significantly lower than that in the control group. Probiotic administration was not associated with a statistically significant reduction in length of hospital stay (MD −1.94, CI −7.17, 3.28; P = 0.47; I2 = 88%), incidence of oro-pharyngeal colonization (OR 0.59, CI 0.33, 1.04; P = 0.07; I2 = 69%), and incidence of diarrhea (OR 0.59, CI 0.34, 1.03; P = 0.06; I2 = 38%). Discussion Our meta-analysis shows that probiotic administration has a promising role in lowering the incidence of VAP, the duration of mechanical ventilation, length of ICU stay, and in-hospital mortality.

The Impact

<b><i>Background:</i></b> Patients with chronic obstructive pulmonary disease (COPD) are at a heightened risk of pneumonia. Whether coexisting community-acquired pneumonia (CAP) can predict increased mortality in hospitalized COPD patients is still controversial. <b><i>Objective:</i></b> This systematic review and meta-analysis aims to assess the association between CAP and mortality and morbidity in COPD patients hospitalized for acute worsening of respiratory symptoms. <b><i>Methods:</i></b> In this review, cohort studies and case-control studies investigating the impact of CAP in hospitalized COPD patients were retrieved from 4 electronic databases from inception until December 2019. Methodological quality of included studies was assessed using Newcastle-Ottawa Quality Assessment Scale. The primary outcome was mortality. The secondary outcomes included length of hospital stay, need for mechanical ventilation, intensive care unit (ICU) admission, length of ICU stay, and readmission rate. The Mantel-Haenszel method and inverse variance method were used to calculate pooled relative risk (RR) and mean difference (MD), respectively. <b><i>Results:</i></b> A total of 18 studies were included. The presence of CAP was associated with higher mortality (RR = 1.85; 95% CI: 1.50–2.30; <i>p</i> &#x3c; 0.00001), longer length of hospital stay (MD = 1.89; 95% CI: 1.19–2.59; <i>p</i> &#x3c; 0.00001), more need for mechanical ventilation (RR = 1.48; 95% CI: 1.32–1.67; <i>p</i> &#x3c; 0.00001), and more ICU admissions (RR = 1.58; 95% CI: 1.24–2.03; <i>p</i> = 0.0002) in hospitalized COPD patients. CAP was not associated with longer ICU stay (MD = 5.2; 95% CI: −2.35 to 12.74; <i>p</i> = 0.18) or higher readmission rate (RR = 1.02; 95% CI: 0.96–1.09; <i>p</i> = 0.47). <b><i>Conclusion:</i></b> Coexisting CAP may be associated with increased mortality and morbidity in hospitalized COPD patients, so radiological confirmation of CAP should be required and more attention should be paid to these patients.

Abstract BackgroundPerioperative diabetes insipidus (DI) is a serious complication occurring in patients undergoing off-pump coronary artery bypass grafting (OPCABG). MethodsThis was a retrospective study of 199 patients who underwent OPCABG surgery in Anzhen hospital, Beijing, China, between January 2019 to December 2019. Patients were divided into a DI(+) group and a DI(-) group according to perioperative urine condition. The incidence of perioperative DI in patients undergoing OPCABG surgery was calculated as the main outcome. Multivariable binary logistic regression analysis was used to identify independent prognostic factors of DI.ResultsPerioperative DI occurred in 43.2% (86/199) of these patients. Mean patient age was 62.5 ± 9.0 years, and 156 (78.4%) were male. Multivariable logistic regression analysis showed a correlation between BMI(OR=0.772, 95%CI[0.670-0.890], P＜0.001), Crystal quantity(OR=1.001, 95%CI[1.000-1.001], P=0.008), perioperative Cr(OR=0.965, 95%CI[0.937-0.993], P=0.016). The DI(+) group had a significantly higher imbalance postoperative PH condition(41.9% vs 28.3%, P<0.05), higher median mechanical ventilation time than the DI(-) group (22.0 vs. 20.5, P<0.01) and higher median of ICU stay hours(27.0 vs 31.0, P=0.041).ConclusionCoronary artery disease(CAD) patients underwent OPCABG surgery were easy to have perioperative DI, which had a higher ICU stay and mechanical ventilation time than those without DI. BMI, Crystal quantity, perioperative creatinine was associated with the presence of DI. Prospective studies are needed to validate these findings.

Abstract OBJECTIVES Our goal was to evaluate, through a systematic review, the efficacy of plasmapheresis in the preoperative preparation of the patient for a thymectomy for the treatment of myasthenia gravis. METHODS MEDLINE, Embase, LILACS, Scopus and CENTRAL databases were searched. The following outcomes were evaluated: myasthenic crisis, mortality, pneumonia, bleeding, use of mechanical ventilation, length of hospital stay and intensive care unit (ICU) stay. RevMan 5.3 software provided by the Cochrane Collaboration was used for the meta-analysis. RESULTS The total number of patients evaluated in the 7 included studies was 360. Plasmapheresis during the preoperative period did not decrease the myasthenic crisis [risk ratio (RR) 0.36, 95% confidence interval (CI) 0.08–1.66; I2 = 44%; 5 studies, 243 patients]. There was also no change in the mortality rate (RR 0.7, 95% CI 0.11–4.62; I2 = 0%; 3 studies, 172 patients) or pneumonia cases (RR 0.28, 95% CI 0.07–1.09; I2 = 27%; 5 studies, 272 patients). Bleeding was greater in patients who underwent plasmapheresis (mean difference 34.34 ml; 95% CI 24.93–43.75; I2 = 0%). We evaluated the following outcomes: need for mechanical ventilation, hospital stay, ICU stay and mechanical ventilation, but these outcomes were not adequate to perform the meta-analysis due to the high heterogeneity among the studies. Subgroup analysis showed that plasmapheresis performed during the preoperative period in patients with severe disease (Osserman III and IV) decreased the myasthenic crisis postoperatively (RR 0.12, 95% CI 0.02–0.65; I2 = 63%). CONCLUSIONS Plasmapheresis may reduce the myasthenic crisis during the postoperative period in patients with severe disease but may produce little or no difference in patients with mild clinical expression of the disease.

Objective. To systematically evaluate the effect of bedside ward round checklists on the clinical outcomes of critical patients and thus provide a scientific and rational basis for decision-making in its clinical application. Methods. PubMed, EMBASE, Web of Science, Cochrane Library, CNKI, and Wanfang databases were searched to collect the literature studies about randomized controlled trials (RCTs) and cohort studies involving the effect of bedside ward round checklists on the clinical outcomes of critical patients, and the retrieval time limit was from the establishment of the database to August 2019. After two researchers independently screened the literature studies, extracted the literature data, and evaluated the risk of bias in included studies, meta-analysis was carried out by using Stata 12.0 software. Results. Two RCTs and nine cohort studies were included in this study. The results of meta-analysis showed that compared with the ordinary bedside ward round, the application of checklist in bedside ward round could shorten the ICU hospitalization time (standardized mean difference (SMD) = – 0.37, 95% CI (– 0.78, 0.04), P  ≤ 0.001) and mechanical ventilation time (SMD = – 0.24, 95% CI (– 0.44, −0.04), P  = 0.037) and reduce the incidence of ventilator-associated pneumonia (VAP) (SMD = 0.61, 95% CI (0.38, 0.99), P  = 0.057) in critical patients. However, there were no significant differences in central venous catheter (CVC) retention time and incidence and mortality of deep venous thrombosis (DVT) between ordinary ward round and bedside ward round checklist. Conclusion. The existing evidence shows that compared with the ordinary ward round, the application of bedside ward round checklists can shorten ICU hospitalization time and mechanical ventilation time and reduce VAP incidence and ICU mortality in critical patients. However, due to the limitations of the quality of the included studies, the above conclusions need to be verified with more high-quality studies.

Abstract Background Although several international guidelines recommend early over late intubation of patients with severe coronavirus disease 2019 (COVID-19), this issue is still controversial. We aimed to investigate the effect (if any) of timing of intubation on clinical outcomes of critically ill patients with COVID-19 by carrying out a systematic review and meta-analysis. Methods PubMed and Scopus were systematically searched, while references and preprint servers were explored, for relevant articles up to December 26, 2020, to identify studies which reported on mortality and/or morbidity of patients with COVID-19 undergoing early versus late intubation. “Early” was defined as intubation within 24 h from intensive care unit (ICU) admission, while “late” as intubation at any time after 24 h of ICU admission. All-cause mortality and duration of mechanical ventilation (MV) were the primary outcomes of the meta-analysis. Pooled risk ratio (RR), pooled mean difference (MD) and 95% confidence intervals (CI) were calculated using a random effects model. The meta-analysis was registered with PROSPERO (CRD42020222147). Results A total of 12 studies, involving 8944 critically ill patients with COVID-19, were included. There was no statistically detectable difference on all-cause mortality between patients undergoing early versus late intubation (3981 deaths; 45.4% versus 39.1%; RR 1.07, 95% CI 0.99–1.15, p = 0.08). This was also the case for duration of MV (1892 patients; MD − 0.58 days, 95% CI − 3.06 to 1.89 days, p = 0.65). In a sensitivity analysis using an alternate definition of early/late intubation, intubation without versus with a prior trial of high-flow nasal cannula or noninvasive mechanical ventilation was still not associated with a statistically detectable difference on all-cause mortality (1128 deaths; 48.9% versus 42.5%; RR 1.11, 95% CI 0.99–1.25, p = 0.08). Conclusions The synthesized evidence suggests that timing of intubation may have no effect on mortality and morbidity of critically ill patients with COVID-19. These results might justify a wait-and-see approach, which may lead to fewer intubations. Relevant guidelines may therefore need to be updated.

Abstract Background A skin flap is one of the most critical surgical techniques for the restoration of cutaneous defects. However, the distal necrosis of the skin flap severely restricts the clinical application of flap surgery. As there is no consensus on the treatment methods to prevent distal necrosis of skin flaps, more effective and feasible interventions to prevent skin flaps from necrosis are urgently needed. Stem therapy as a potential method to improve the survival rate of skin flaps is receiving increasing attention. Methods This review followed the recommendations from the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statements. Twenty studies with 500 animals were included by searching Web of Science, EMBASE, PubMed, and Cochrane Library databases, up until October 8, 2020. Moreover, the references of the included articles were searched manually to obtain other studies. All analyses were conducted using Review Manager V.5.3 software. Results Meta-analysis of all 20 studies demonstrated stem cell treatment has significant effects on reducing necrosis of skin flap compared with the control group (SMD: 3.20, 95% CI 2.47 to 3.93). Besides, subgroup analysis showed differences in the efficacy of stem cells in improving the survival rate of skin flaps in areas of skin flap, cell type, transplant types, and method of administration of stem cells. The meta-analysis also showed that stem cell treatment had a significant effect on increasing blood vessel density (SMD: 2.96, 95% CI 2.21 to 3.72) and increasing the expression of vascular endothelial growth factor (VEGF, SMD: 4.34, 95% CI 2.48 to 6.1). Conclusions The preclinical evidence of our systematic review indicate that stem cell-based therapy is effective for promoting early angiogenesis by up regulating VEGF and ultimately improving the survival rate of skin flap. In summary, small area skin flap, the administration method of intra-arterial injection, ASCs and MSCs, and xenogenic stem cells from humans showed more effective for the survival of animal skin flaps. In general, stem cell-based therapy may be a promising method to prevent skin flap necrosis.

Purpose: Mini-dental implants (MDIs) have been used to support and retain overdentures, providing patients with a less invasive placement procedure. Although lucrative, the use of MDIs to retain a maxillary overdenture is still not an established treatment modality. This systematic review aims to answer the question: Do mini-implant-retained maxillary overdentures provide a satisfactory treatment outcome for complete edentulism? Methods: A systematic search for relevant articles was conducted to include articles published until April 2021 in the following electronic databases: CINAHL, Cochrane, EMBASE, PubMed, and Web of Science. All empirical studies evaluating the biological, survival, or patient-reported outcomes after placing mini-implant-retained overdentures in maxilla were considered for inclusion. The risk of bias was assessed by utilizing the Joanna Briggs Institute critical appraisal checklist. Study screening and data extraction were conducted by three reviewers independently. Results: The electronic search retrieved 1276 titles after omitting duplicates. Twenty articles were considered for full-text review, of which six studies were included in this systematic review. The included studies evaluated a total of 173 participants with a mean age of 66.3 years. The overall mini-implant survival rate was 77.1% (95% CI: 64.7–89.5%) with a mean follow-up time of 1.79 years (range: 6 months to 3 years). Implant survival differed significantly when comparing complete and partial palatal coverage overdentures. Those with complete palatal coverage exhibited less bone loss overall compared to partial coverage overdentures. Participants of all studies reported an increase in the quality of life and in satisfaction after rehabilitation treatment with MDIs. Conclusions: The survival rate of mini-implants retaining an overdenture in the maxilla was observed to be lower than the values reported for traditional implants in the literature. Improvements were observed in all aspects in terms of patient satisfaction, quality of life, oromyofunction, and articulation after the treatment.
