Abstract
We performed a meta-analysis to evaluate the effect of platelet-rich plasma vs standard management for the treatment of diabetic foot ulcer wounds. A systematic literature search up to March 2022 was performed and 1435 subjects with diabetic foot ulcer wounds at the baseline of the studies; 723 of them were treated with platelet-rich plasma, and 712 used control. Odds ratio (OR) with 95% confidence intervals (CIs) was calculated to assess the effect of platelet-rich plasma vs standard management for the treatment of diabetic foot ulcer wounds using the dichotomous method with a random or fixed-effect model. The use of autologous platelet-rich plasma resulted in significantly higher complete-healed diabetic foot ulcer wounds compared with control (OR, 1.95; 95% CI, 1.49-2.56, P < 0.001). The use of allogeneic platelet-rich plasma resulted in significantly higher complete-healed diabetic foot ulcer wounds compared with control (OR, 6.19; 95% CI, 2.32-16.56, P < 0.001). The use of autologous and allogeneic platelet-rich plasma resulted in significantly higher complete-healed diabetic foot ulcer wounds compared with control. Though, the analysis of outcomes should be with caution because of the low number of studies in certain comparisons, for example, allogeneic platelet-rich plasma compared with control.

BMC neurology. 2021;21(1):294
Abstract
OBJECTIVE To compare the effectiveness of various drug interventions in improving the clinical outcome of postoperative patients after aneurysmal subarachnoid hemorrhage (aSAH) and assist in determining the drugs of definite curative effect in improving clinical prognosis. METHODS Eligible Randomized Controlled Trials (RCTs) were searched in databases of PubMed, EMBASE, and Cochrane Library (inception to Sep 2020). Glasgow Outcome Scale (GOS) score, Extended Glasgow Outcome Scale (GOSE) score or modified Rankin Scale (mRS) score was used as the main outcome measurements to evaluate the efficacy of various drugs in improving the clinical outcomes of postoperative patients with aSAH. The network meta-analysis (NMA) was conducted based on a random-effects model, dichotomous variables were determined by using odds ratio (OR) with 95% confidence interval (CI), and a surface under the cumulative ranking curve (SUCRA) was generated to estimate the ranking probability of comparative effectiveness among different drug therapies. RESULTS From the 493 of initial citation screening, forty-four RCTs (n = 10,626 participants) were eventually included in our analysis. Our NMA results showed that cilostazol (OR = 3.35,95%CI = 1.50,7.51) was the best intervention to improve the clinical outcome of patients (SUCRA = 87.29%, 95%CrI 0.07-0.46). Compared with the placebo group, only two drug interventions [nimodipine (OR = 1.61, 95%CI 1.01,2.57) and cilostazol (OR = 3.35, 95%CI 1.50, 7.51)] achieved significant statistical significance in improving the clinical outcome of patients. CONCLUSIONS Both nimodipine and cilostazol have exact curative effect to improve the outcome of postoperative patients with aSAH, and cilostazol may be the best drug to improve the outcome of patients after aSAH operation. Our study provides implications for future studies that, the combination of two or more drugs with relative safety and potential benefits (e.g., nimodipine and cilostazol) may improve the clinical outcome of patients more effectively.

Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology. 2021
Abstract
Human serum albumin has shown remarkable efficacy in rodent models of ischemic stroke, while results from relevant clinical research on albumin therapy remain controversial. We conducted a meta-analysis of published studies to quantitatively analyze the neurofunctional outcomes of patients with ischemic stroke treated with albumin. PubMed, Embase, and Cochrane Library were searched in July 2020. A total of four studies and 1611 patients were included. The aggregated results indicated that there were 635 patients with good neurological outcomes, among which 321 patients were in the albumin group (39.8%) and 314 patients in the control group (39.1%), showing no statistically significant difference between the albumin and control groups (OR = 1.04, 95% CI 0.85-1.27). The results suggest that albumin therapy at the acute stage of ischemic stroke has no beneficial effect on the long-term neurological function of patients with ischemic stroke. Considering pulmonary edema and other complications are more likely to occur in such patients after albumin infusion, the administration of albumin therapy for acute ischemic stroke should be done with utmost caution.

Zheng Z, Huang Y, Wang Z, Tang J, Chen X, Li Y, Li M, Zang C, Wang Y, Wang L, et al
Frontiers in cardiovascular medicine. 2021;8:736352
Abstract
Objective: This study aimed to identify the clinical features of Kawasaki disease shock syndrome (KDSS) in children. Methods: The case-control studies of KDSS and KD children up until April 30, 2021 were searched in multiple databases. The qualified research were retrieved by manually reviewing the references. Review Manager 5.3 software was used for statistical analysis. Results: The results showed that there was no significant difference in the incidence of male and female in children with KDSS. Children with KDSS compared with non-shocked KD, there were significant difference in age, duration of fever, white blood cell (WBC) count, percentage of neutrophils (NEUT%), platelet count (PLT), c-reactive protein level (CRP), alanine transaminase concentration (ALT), aspartate transaminase concentration (AST), albumin concentration (ALB), sodium concentration (Na), ejection fraction, and length of hospitalization as well as the incidence of coronary artery dilation, coronary artery aneurysm, left ventricular dysfunction, mitral regurgitation, pericardial effusion, initial diagnosis of KD, intravenous immunoglobulin (IVIG) resistance and receiving second dose of IVIG, vasoactive drugs, hormones, and albumin. In contrast, there was no difference in the hemoglobin concentration, erythrocyte sedimentation rate, and the incidence of conjunctival injection, oropharyngeal change, polymorphous rash, extremity change, and incomplete KD. Conclusion: Current evidence suggested that the children with KDSS had more severe indicators of inflammation and more cardiac abnormalities. These patients were resistant to immunoglobulin treatment and required extra anti-inflammatory treatment. Systematic Review Registration: PROSPERO registration number CRD42021241207.

Abstract
Objective: Anemia is frequent in patients with acute myocardial infarction (AMI), and the optimal red blood cell transfusion strategy for AMI patients with anemia is still controversial. We aimed to compare the efficacy of restrictive and liberal red cell transfusion strategies in AMI patients with anemia. Methods: We systematically searched PubMed, EMBASE, Web of Science, Cochrane Library, and Clinicaltrials.gov, from their inception until March 2021. Studies designed to compare the efficacy between restrictive and liberal red blood cell transfusion strategies in patients with AMI were included. The primary outcome was all-cause mortality, including overall mortality, in-hospital or follow-up mortality. Risk ratios (RR) with 95% confidence intervals (CI) were presented and pooled by random-effects models. Results: The search yielded a total of 6,630 participants in six studies. A total of 2,008 patients received restrictive red blood cell transfusion while 4,622 patients were given liberal red blood cell transfusion. No difference was found in overall mortality and follow-up mortality between restrictive and liberal transfusion groups (RR = 1.07, 95% CI = 0.82-1.40, P = 0.62; RR = 0.89, 95% CI = 0.56-1.42, P = 0.62). However, restrictive transfusion tended to have a higher risk of in-hospital mortality compared with liberal transfusion (RR = 1.22, 95% CI = 1.00-1.50, P = 0.05). No secondary outcomes, including follow-up reinfarction, stroke, and acute heart failure, differed significantly between the two groups. In addition, subgroup analysis showed no differences in overall mortality between the two groups based on sample size and design. Conclusion: Restrictive and liberal red blood cell transfusion have a similar effect on overall mortality and follow-up mortality in AMI patients with anemia. However, restrictive transfusion tended to have a higher risk of in-hospital mortality compared with liberal transfusion. The findings suggest that transfusion strategy should be further evaluated in future studies.
PICO Summary
Population

Zheng Q, Yang H, Sun L, Wei R, Fu X, Wang Y, Huang Y, Liu YN, Liu WJ
Pharmacol Res. 2020;:105020
Abstract
Hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) are a new class of oral medicines being developed for the treatment of anemia in chronic kidney disease (CKD) patients. This study aimed to compare the efficacy and safety of HIF-PHI vs epoetin and darbepoetin in CKD patients with anemia not undergoing dialysis. The PubMed, Embase, Cochrane Library, Web of Science, and http://clinicaltrials.gov/ clinicaltrials.gov databases were searched from inception to October 2019 for randomized controlled trials investigating different agents (six HIF-PHIs, epoetin, darbepoetin, and placebo) for treating CKD patients with anemia that did not undergo dialysis. The outcomes included a change in hemoglobin (Hb) levels and all-cause mortality. A total of 19 studies were included. Compared with the placebo, except for vadadustat (mean differences: 1.12, 95% confidence interval [CI]: 0.11-2.35), the other drugs significantly increased Hb levels, with mean differences of 2.46 (95% CI: 0.933.99) for desidustat, 1.81 (0.872.75) for enarodustat, 1.68 (0.642.72) for molidustat, 1.66 (0.892.44) for epoetin, 1.63 (0.692.56) for darbepoetin, 1.61 (0.992.22) for roxadustat, and 1.55 (0.742.36) for daprodustat. No differences were found in the Hb level elevations among these eight drugs. Compared with the placebo, there also was no significant association between the drugs and all-cause mortality (molidustat of RR, 0.39 [95% CI, 0.062.59]; roxadustat, 0.40 (0.062.84); enarodustat, 0.33 (0.0116.25); desidustat, 0.34 (0.0117.00); epoetin, 0.50 (0.181.42); daprodustat, 0.54 (0.093.31); darbepoetin, 1.03 (0.651.65); and vadadustat, 1.43 (0.1513.27)). No differences were observed in the all-cause mortality among the drugs. In conclusion, these HIF-PHIs are effective and relatively tolerant for treating anemia patients with CKD not undergoing dialysis. Further research should consider the limitations of our study to evaluate the value of these HIF-PHIs in clinical settings.

Abstract
BACKGROUND Convalescent plasma administration may be of clinical benefit in patients with severe influenza, but reports on the efficacy of this therapy vary. METHODS We conducted a systematic review and meta-analysis assessing randomized controlled trials (RCTs) involving the administration of convalescent plasma to treat severe influenza. Healthcare databases were searched in February 2020. All records were screened against eligibility criteria, and the risks of bias were assessed. The primary outcome was the fatality rate. RESULTS A total of 2861 studies were retrieved and screened. Five eligible RCTs were identified. Pooled analyses yielded no evidence that using convalescent plasma to treat severe influenza resulted in significant reductions in mortality (odds ratio, 1.06; 95% CI, 0.51-2·23; P = 0.87; I(2) = 35%), number of days in the intensive care unit, or number of days on mechanical ventilation. This treatment may have the possible benefits of increasing hemagglutination inhibition titers and reducing influenza B viral loads and cytokine levels. No serious adverse events were reported. The included studies were generally of high quality with a low risk of bias. CONCLUSIONS The administration of convalescent plasma appears safe but may not reduce the mortality, number of days in the intensive care unit, or number of days on mechanical ventilation in patients with severe influenza.
PICO Summary
Population
Patients hospitalized with severe influenza (5 studies, n= 598).
Intervention
Convalescent plasma or hyperimmune intravenous immunoglobulin (H-IVIG).
Comparison
Various comparators (normal intravenous immunoglobulin, standard care, low-titre anti-influenza, placebo).
Outcome
Pooled analyses yielded no evidence that using convalescent plasma to treat severe influenza resulted in significant reductions in mortality, number of days in the intensive care unit, or number of days on mechanical ventilation.

Norepinephrine vs vasopressin: which vasopressor should be discontinued first in septic shock? a meta-analysis
Wu Z, Zhang S, Xu J, Xie J, Huang L, Huang Y, Yang Y, Qiu H
Shock (Augusta, Ga.). 2019
Abstract
BACKGROUND Patients with septic shock in whom Norepinephrine (NE) infusion alone is insufficient to raise blood pressure require the concomitant administration of Vasopressin (VP). However, current guidelines do not advise clinicians as to which vasoactive agent to discontinue first once the patient's septic shock begins to resolve. Moreover, there is controversial data guiding clinicians on how to discontinue vasopressors for septic shock patients who are receiving a combination therapy of NE and VP. METHODS The PubMed, Embase and Cochrane Central Register databases were searched from the database inception until October 18, 2018. Studies were limited to adult patients with septic shock who received concomitant NE and VP treatment, that included different orders of vasopressor discontinuation. The primary outcome was the incidence of hypotension. Overall mortality, ICU mortality and length of stay in the ICU (LOS) were secondary outcomes. Sensitivity and subgroup analyses, as well as trial sequential analysis (TSA), were performed. RESULTS One prospective randomized controlled trial and seven retrospective cohort studies were included in present meta-analysis. Compared with discontinuing VP first, the incidence of hypotension was significantly lower when NE was discontinued first (OR 0.3, 95% CI 0.10 to 0.86, P = 0.02; I = 91%). No significant difference was detected in either overall mortality (OR 1.28, 95% CI 0.77 to 2.10, P = 0.34) or ICU mortality (OR 0.99, 95% CI 0.74 to 1.34, P = 0.96) between these two groups. Furthermore, ICU length of stay (LOS) was also evaluated in five studies, and no statistical significance was observed between the two groups with different orders in weaning vasopressors (mean difference, 1.35, 95% CI -2.05 to 4.74, P = 0.44). The subgroup analyses suggested a significant association between hypotension and the practice of discontinuing VP first specifically in patients with a low usage rate of corticosteroids (OR 0.18, 95% CI 0.04 to 0.78, P = 0.02). The TSA indicated a lack of sufficient evidence to draw conclusions from the current results (RIS = 11,821). CONCLUSIONS In adults with septic shock treated with concomitant VP and NE therapy, discontinuing VP first may lead to a higher incidence of hypotension but is not associated with mortality or ICU LOS. Further prospective studies with larger sample sizes are warranted.

Guo J C, Zheng Y, Chen H T, Zhou H, Huang X H, Zhong L P, Zhou H B, Huang Y, Xie D L, Lou Y L
Oncotarget. 2018;9((6)):7112-7125.
Abstract
Background and Aim: Thrombopoietin receptor agonists (TPO-RAs) have been shown to be safe and effective for adults with chronic immune thrombocytopenia (ITP). The aim of this meta-analysis is to assess the efficacy and safety of thrombopoietin receptor agonists for children with chronic ITP. Materials and Methods: Clinical randomized controlled trials (RCTs) evaluating the efficacy and safety of TPO-RAs in pediatric ITP patients published up to June 2017 were retrieved from PubMed, Cochrane Library, and Embase databases. Relevant data were extracted, and the Physiotherapy Evidence Database scale was used to assess the methodological quality. Stata/SE 12.0 was used to perform a meta-analysis. Results: Seven RCTs were included, with 238 patients and 107 patients in the TPO-RA group and the control group, respectively. Assessing efficacy, better results were found in the TPO-RA group for the rate of overall platelet response, durable response, and rescue medication needed. Furthermore, the TPO-RA group yielded superior results in the incidence of clinically significant bleeding events but had a comparable result in the incidence of any bleeding events and severe bleeding events. No significant difference was found between the two groups in health-related quality of life and parental burden. Assessing safety, no significant difference was found between the two groups in the incidence of any adverse events and severe adverse events. Conclusions: TPO-RAs are effective and safe agents for the treatment of chronic ITP in pediatric patients. Eltrombopag appears to be better than romiplostim in terms of the rate of rescue medication needed and clinically significant bleeding events.

He Y, Chen J, Huang Y, Pan Q, Nie M
Journal of Oral and Maxillofacial Surgery : Official Journal of the American Association of Oral and Maxillofacial Surgeons. 2017;75((12):):2497-2506
Abstract
PURPOSE Application of platelet-rich fibrin (PRF) during tooth extraction is able to accelerate wound healing, stimulate osseous and soft tissue regeneration, and reduce unwanted side effects. The aim of this meta-analysis was to investigate the effect of local application of PRF on controlling postoperative signs and symptoms after the extraction of an impacted lower third molar. MATERIALS AND METHODS A systematic search of PubMed, Web of Science, Embase, and the Cochrane Library was performed to identify all studies published up to October 2016 that investigated the effect of PRF on lower third molar extraction. Pain, swelling, trismus, alveolar osteitis (AO), and osteoblastic activity were extracted to evaluate the effect of PRF. After quality assessment, meta-analysis was performed with RevMan software (version 5.3; Cochrane Library Software, Oxford, UK). RESULTS After the search and selection process, 10 studies were selected in this meta-analysis, including 468 cases of PRF application and 467 cases of non-PRF application. Of the studies, 9 were randomized controlled trials, including 7 split-mouth studies, and there was 1 retrospective case-control study. The results indicated that PRF significantly relieves pain (P = .01) and 3-day postoperative swelling (P = .03) and reduces the incidence of AO (P < .0001). However, there were no significant differences between the PRF and non-PRF groups with respect to 1-day postoperative swelling and osteoblastic activity. CONCLUSIONS Local application of PRF after lower third molar extraction is a valid method for relieving pain and 3-day postoperative swelling and reducing the incidence of AO. For patients undergoing complicated surgical extraction, PRF might be a recommendation for local application into the sockets.
