Abstract
BACKGROUND Red-cell transfusion is critical for surgery during the peri-operative period; however, the transfusion threshold remains controversial mainly owing to the diversity among patients. The patient's medical status should be evaluated before making a transfusion decision. Herein, we developed an individualized transfusion strategy using the West-China-Liu's Score based on the physiology of oxygen delivery/consumption balance and designed an open-label, multicenter, randomized clinical trial to verify whether it reduced red cell requirement as compared with that associated with restrictive and liberal strategies safely and effectively, providing valid evidence for peri-operative transfusion. METHODS Patients aged >14 years undergoing elective non-cardiac surgery with estimated blood loss > 1000 mL or 20% blood volume and hemoglobin concentration <10 g/dL were randomly assigned to an individualized strategy, a restrictive strategy following China's guideline or a liberal strategy with a transfusion threshold of hemoglobin concentration <9.5 g/dL. We evaluated two primary outcomes: the proportion of patients who received red blood cells (superiority test) and a composite of in-hospital complications and all-cause mortality by day 30 (non-inferiority test). RESULTS We enrolled 1182 patients: 379, 419, and 384 received individualized, restrictive, and liberal strategies, respectively. Approximately 30.6% (116/379) of patients in the individualized strategy received a red-cell transfusion, less than 62.5% (262/419) in the restrictive strategy (absolute risk difference, 31.92%; 97.5% confidence interval [CI]: 24.42-39.42%; odds ratio, 3.78%; 97.5% CI: 2.70-5.30%; P<0.001), and 89.8% (345/384) in the liberal strategy (absolute risk difference, 59.24%; 97.5% CI: 52.91-65.57%; odds ratio, 20.06; 97.5% CI: 12.74-31.57; P<0.001). No statistical differences were found in the composite of in-hospital complications and mortality by day 30 among the three strategies. CONCLUSION The individualized red-cell transfusion strategy using the West-China-Liu's Score reduced red-cell transfusion without increasing in-hospital complications and mortality by day 30 when compared with restrictive and liberal strategies in elective non-cardiac surgeries.

European journal of clinical pharmacology. 2022;:1-18
Abstract
PURPOSE The coronavirus disease 2019 (COVID-19) pandemic has shown unprecedented impact world-wide since the eruption in late 2019. Importantly, emerging reports suggest an increased risk of thromboembolism development in patients with COVID-19. Meanwhile, it is found that aspirin reduced mortality in critically ill patients with non-COVID-19 acute respiratory distress syndrome. Therefore, a meta-analysis was performed to investigate the effects of aspirin on COVID-19 mortality. METHODS A systematic literature search was conducted in 10 electronic databases and 4 registries. Random effects models were used to calculate pooled relative risks (RRs) with 95% confidence intervals (Cis) to estimate the effect of aspirin on COVID-19 mortality. Relevant subgroup analyses and sensitivity analyses were also performed. RESULTS The results showed that aspirin use was associated with a reduction in COVID-19 mortality (adjusted RR 0.69; 95% CI 0.50-0.95; P < 0.001). Subgroup analysis found that the low-dose group was associated with a reduced COVID-19 mortality (adjusted RR 0.64; 95% CI 0.48-0.85; P < 0.01). Aspirin use was associated with reduced COVID-19 mortality in Europe and America (crude RR 0.71; 95% CI 0.52-0.98; P = 0.04), and results from cohort studies suggested that aspirin use was a protective factor for COVID-19 mortality (adjusted RR 0.73; 95% CI 0.52-0.99; P = 0.04). Meanwhile, aspirin use was not associated with bleeding risk (crude RR 1.22; 95% CI 0.80-1.87; P = 0.96). CONCLUSIONS This meta-analysis found that aspirin use was associated with a reduction in mortality in patients with COVID-19 and not with an increased risk of bleeding.

Thrombosis journal. 2022;20(1):47
Abstract
BACKGROUND Previous studies demonstrate a reduced risk of thrombosis and mortality with anticoagulant treatment in patients with COVID-19 than in those without anticoagulation treatment. However, an open question regarding the efficacy and safety of therapeutic anticoagulation (T-AC) versus a lower dose, prophylaxis anticoagulation (P-AC) in COVID-19 patients is still controversial. METHODS We systematically reviewed currently available randomized clinical trials (RCTs) and observational studies (OBs) from January 8, 2019, to January 8, 2022, and compared prophylactic and therapeutic anticoagulant treatment in COVID-19 patients. The primary outcomes were risk of mortality, major bleeding, and the secondary outcomes included venous and arterial thromboembolism. Subgroup analysis was also performed between critically ill and non-critically ill patients with COVID-19 and between patients with higher and lower levels of D-dimer. Sensitivity analysis was performed to decrease the bias and the impact of population heterogeneity. RESULTS We identified 11 RCTs and 17 OBs fulfilling our inclusion criteria. In the RCTs analyses, there was no statistically significant difference in the relative risk of mortality between COVID-19 patients with T-AC treatment and those treated with P-AC (RR 0.95, 95% CI, 0.78-1.15, P = 0.60). Similar results were also found in the OBs analyses (RR 1.21, 95% CI, 0.98-1.49, P = 0.08). The pooling meta-analysis using a random-effects model combined with effect sizes showed that in the RCTs and OBs analyses, patients with COVID-19 who received T-AC treatment had a significantly higher relative risk of the major bleeding event than those with P-AC treatment in COVID-19 patients (RCTs: RR 1.76, 95% CI, 1.19-2.62, P = 0.005; OBs: RR 2.39, 95% CI, 1.56-3.68, P < 0.0001). Compared with P-AC treatment in COVID-19 patients, patients with T-AC treatment significantly reduced the incidence of venous thromboembolism (RR 0.51, 95% CI, 0.39-0.67, P<0.00001), but it is not associated with arterial thrombosis events (RR 0.97, 95% CI, 0.66-1.42, P = 0.87). The subgroup analysis of OBs shows that the mortality risk significantly reduces in critically ill COVID-19 patients treated with T-AC compared with those with P-AC treatment (RR 0.58, 95% CI, 0.39-0.86, P = 0.007), while the mortality risk significantly increases in non-critically ill COVID-19 patients treated with T-AC (RR 1.56, 95% CI, 1.34-1.80, P < 0.00001). In addition, T-AC treatment does not reduce the risk of mortality in COVID-19 patients with high d-dimer levels in RCTs. Finally, the overall sensitivity analysis after excluding two RCTs studies remains consistent with the previous results. CONCLUSIONS In our integrated analysis of included RCTs and OBs, there is no significant difference between the mortality of T-AC and P-AC treatment in unselected patients with COVID-19. T-AC treatment in COVID-19 patients significantly reduced the incidence of venous thromboembolism but showed a higher risk of bleeding than those with P-AC treatment. In addition, P-AC treatment was superior to T-AC treatment in non-critically ill COVID-19 patients, the evidence supporting the necessity for T-AC treatment in critically ill COVID-19 patients came only from OBs. TRIAL REGISTRATION Protocol registration: The protocol was registered at PROSPERO (CRD42021293294).

Abstract
IMPORTANCE Studies have identified platelet-rich plasma (PRP) as a novel adjuvant therapy in AGA. However, the efficacy of PRP still needs to be improved. OBJECTIVE To assess the efficacy of PRP plus basic fibroblast growth factor (PRPF) for the treatment of AGA. DESIGN, SETTING, AND PARTICIPANTS This was a prospective randomized, double-blind, placebo-controlled, half-head study. 80 patients whose AGA staged Norwood-Hamilton III-VII or Ludwig I-III were enrolled in the study from February 2019 to September 2019. INTERVENTIONS Patients were randomly divided into two groups of 40 patients each and were given the following treatment: (Group1) PRPF was injected in right-half and left-half with placebo; (Group2) PRPF was injected in right-half and left-half with PRP. MAIN OUTCOMES AND MEASURES The treatment was processed 3 times, 1 month apart. Hair growth parameters were evaluated by trichoscope monthly until the sixth month of the study. Patients' satisfaction, hair pull test and side effects were recorded during follow-up. RESULTS Of the 80 patients included in the study, 47 were men and 33 were women with a mean age of 28.96±4.82 (ranged from 21 to 46). Both PRP and PRPF showed positive improvement (p<0.05) on hair count, terminal hair and anagen hair after the treatment. Efficacy of PRPF revealed a significant improvement(p<0.05) in hair count, terminal hair, vellus hair and anagen hair versus PRP. There was no statistical difference among any of the parameters in the placebo group. CONCLUSIONS AND RELEVANCE PRPF can be a safe and valuable form of AGA treatment, and has proven to be more effective than PRP. TRIAL REGISTRATION Reviewed and approved by research ethics board at Nanfang Hospital, Southern Medical University NFEC-2019-212.

Sun Y, Xiao D, Fu W, Cai W, Huang X, Li Q, Li J
Journal of clinical medicine. 2022;11(23)
Abstract
BACKGROUND Visual clarity during shoulder arthroscopy can ensure an efficient and effective performance of the procedure, and it is highly related to bleeding without a tourniquet. Tranexamic acid (TXA) is widely used in adult reconstruction procedures; however, its use in shoulder arthroscopic operations is a relatively novel topic. PURPOSE To analyze the available literature on visual clarity, blood loss, pain control, functional outcomes, and complications after the administration of tranexamic acid in shoulder arthroscopic surgery. METHODS A literature search was performed to retrieve randomized controlled trials examining the use of tranexamic acid at the time of shoulder arthroscopic surgery. The literature search included the MEDLINE, Embase, Web of Science, and Cochrane Library databases. The primary outcomes included visual clarity, blood loss, and visual analog scale scores for pain. Secondary outcomes were operative time, irrigation amount used, postoperative shoulder swelling, the need for pressure increase, mean arterial pressure (MAP), functional outcomes, postoperative adverse effects such as deep venous thrombosis, and pulmonary embolism. The outcomes were pooled to perform a meta-analysis. RESULTS Seven prospective randomized controlled trials met the inclusion criteria for analysis. All of the included studies performed arthroscopic rotator cuff repair. No significant difference in visual clarity was observed (SMD (standardized mean difference), 0.45 [95% CI(confidence interval), -0.68, 1.59]; p = 0.44) nor in pain score (MD (mean difference), -0.46 [95% CI, -0.97, 0.05]; p = 0.08) between the TXA group and the control group. Two studies found no significant difference in blood loss between the TXA group and the control group. The meta-analysis from five studies demonstrated no significant difference between the TXA and control groups in operative time (MD, -3.51 [95% CI, -15.82, 8.80]; p = 0.58) or irrigation amount used (MD, -2.53 [95% CI, -5.93, 0.87]; p = 0.14). Two trials reported different statistical results in postoperative shoulder swelling. No significant differences regarding the need for pressure increase and MAP were reported between groups. No wound complications or infections or cardiac, thrombotic, or thromboembolic complications were recorded in either group. CONCLUSION The use of intravenous or local TXA in shoulder arthroscopic surgery did not increase complications or thromboembolic events, but TXA had no obviously effect of reducing bleeding to obtain a clear visual field or pain release in patients undergoing shoulder arthroscopic surgery.

Abstract
Background: Until now, transfusion-related acute lung injury (TRALI) has been considered to be the leading cause of blood transfusion-related diseases and death. And there is no clinically effective treatment plan for TRALI. The aim of this study was to systematically summarize the literature on risk factors for TRALI in critical patients.Methods: Electronic searches (up to March 2020) were performed in the Cochrane Library, Web of Knowledge, Embase, and PubMed databases. We included studies reporting on the risk factors of TRALI for critical patients and extracted the risk factors. Finally, thirteen studies met the inclusion criteria.Results: We summarized and analyzed the potential risk factors of TRALI for critical patients in 13 existing studies. The host-related factors were age (odds ratio (OR) [95% confidence interval] = 1.16 [1.08-1.24]), female sex (OR = 1.26 [1.16-1.38]), tobacco use status (OR = 3.82 [1.91-7.65]), chronic alcohol abuse (OR = 3.82 [2.97-26.83]), positive fluid balance (OR = 1.24 [1.08-1.42]), shock before transfusion (OR = 4.41 [2.38-8.20]), and ASA score of the recipients (OR = 2.72 [1.43-5.16]). The transfusion-related factors were the number of transfusions (OR = 1.40 [1.14-1.72]) and fresh frozen plasma (FFP) units (OR = 1.21 [1.01-1.46]). The device-related factor was mechanical ventilation (OR = 4.13 [2.20-7.76]).Conclusions: The risk factors for TRALI in this study included Number of transfusions and FFP units were positively correlated with TRALI. Age, female sex, tobacco use, chronic alcohol abuse, positive fluid balance, shock before transfusion, ASA score and mechanical ventilation may be potential risk factors for TRALI. Our study suggests that host-related risk factors may play a more important role in the occurrence and development of TRALI than blood transfusion-related risk factors.

American journal of translational research. 2021;13(5):5691-5696
Abstract
Purpose: To study the effect of systematic nursing on patients with dysfunctional uterine bleeding and rehabilitation. Methods: 98 patients who were treated in our hospital for dysfunctional uterine bleeding from May 2017 to May 2019 were selected, and were divided into a control group (n=49, conventional nursing) and an observation group (n=49, systematic nursing) according to the random number table method. The curative effect, uterine bleeding time, normalization time of biochemical index recovery, psychologic status, quality of life, and nursing satisfaction of the two groups were compared. Results: The efficacy rate of the observation group (93.88%) was higher than the control group (77.55%); the observation group had less uterine bleeding time and activated partial thromboplastin time (APTT) in comparison with the control group (P<0.05). There was no significant difference in self-rating anxiety scale (SAS) and self-rating depression scale (SDS) scores between the two groups before intervention (P>0.05); after intervention, the SAS and SDS scores of both groups decreased, with the observation group being more significant (P<0.05. The quality of life score and nursing satisfaction rate of the observation group were higher (P<0.05). Conclusion: Systematic nursing can improve the curative effect of patients with dysfunctional uterine bleeding, accelerate the rehabilitation process, relieve negative emotions, and improve the quality of life and nursing satisfaction.

Abstract
OBJECTIVE To evaluate efficacy of platelet-rich plasma (PRP) injection in carpal tunnel syndrome (CTS), we conducted this meta-analysis, as well as proposed a protocol for its application in curative processes. METHODS All randomized controlled trials (RCTs) of PRP for the management of mild or moderate CTS were included in this study. Database search was conducted from study inception to July 2020, including PubMed, Embase, Web of Science, and Cochrane Library. We used visual analogue scores (VAS) and the Boston Carpal Tunnel Questionnaire (BCTQ) as evaluation tools for primary outcomes. Second outcomes comprised cross-sectional area (ΔCSA) and electrophysiological indexes including distal motor latency (DML), sensory peak latency (SPL), motor nerve conduction velocity (MNCV), sensory nerve conduction velocity (SNCV), compound muscle action potential (CMAP), and sensory nerve action potential (SNAP). The pooled data were analyzed using RevMan 5.3. Subgroup and sensitivity analyses were conducted with the evidence of heterogeneity. Egger' test was used to investigate publication bias. RESULTS 9 RCTs were finally screened out with 434 patients included. Control groups comprised corticosteroid injection in 5 trials, saline injection in 1 trial, and splint in 3 trials. At the 1st month after follow-up, only ΔCSA between the PRP group and the control group showed significant difference (P < 0.05). In the 3rd month, there were statistically significant differences in VAS, BCTQ, SPL, SNCV, and ΔCSA between two groups (P < 0.05), while no statistically significant differences were found in the remaining outcomes. In the 6th month, there were statistically significant differences at BCTQ (P < 0.05) in primary outcomes and ΔCSA (P < 0.05) in secondary outcomes between two groups. As to adverse events in PRP injection, only one study reported increased pain sensation within 48 h after injections. CONCLUSION This systematic review and meta-analysis demonstrates that the PRP could be effective for mild to moderate CTS and superior to traditional conservative treatments in improving pain and function and reducing the swelling of the median nerve for a mid-long-term effect. To some extent, the electrophysiological indexes also improved after PRP injection compared with others conservative treatments.

Dai J, Jiang C, Sun Y, Chen H
J Diabetes Complications. 2020;:107611
Abstract
BACKGROUND This study will explore the effectiveness and safety of autologous PRP in the treatment of patients with DFU. METHODS The electronic databases of PubMed, EMBASE, BIOSIS, Cochrane central, and Google Scholar internet were searched updated on Jan 30, 2020. Evaluated outcomes included rate of complete ulcer healing, time to healing and adverse events. Statistical analysis was performed with RevMan 5.0 software and STATA 10.0 software. RESULTS Ten RCTs with 456 patients were included in this study. The meta-analysis showed a higher complete ulcer healing rate (RR=1.32, 95% CI 1.06 to 1.65, P=0.01, I(2)=57%), a shorter healing time (MD=-23.42, 95% CI -37.33 to -9.51, P=0.01, I(2)=78%), with no increasing the incidence of adverse events (RR=0.48, 95% CI 0.22 to 1.05, P=0.75, I(2)=0%) in PRP group compared with control. Mixed evidence was seen for publication bias, but analyses by using the trim-and-fill method did not appreciably alter results. CONCLUSION Our findings suggest that autologous PRP may improve the complete ulcer healing rate, shorten the healing time, with no increasing the incidence of adverse events.

Huang X, Sun Y, Su G, Li Y, Shuai X
International heart journal. 2019
Abstract
The efficacy of intravenous immunoglobulin (IVIG) in the treatment of acute myocarditis remains controversial. The aim of this study was to conduct a meta-analysis to assess the efficacy of IVIG in children and adults with acute myocarditis.We searched PubMed, Scopus, Embase, Medline, the Cochrane Library, Google Scholar, and the ClinicalTrials.gov website. Eligible studies were clinical trials of patients with acute myocarditis who received IVIG therapy. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the outcomes.Thirteen studies with 1534 cases were incorporated into our meta-analysis. Pooled results showed that IVIG therapy significantly reduced in-hospital mortality (OR: 0.44, 95% CI 0.17 to 0.71, P < 0.001) and improved the left ventricular ejection fraction (LVEF) (OR: 1.73, 95% CI 1.34 to 2.13, P < 0.001) in acute myocarditis patients. Furthermore, patients with acute fulminant myocarditis (AFM) exhibited a significantly higher survival rate (OR: 2.80, 95% CI 1.16 to 6.77, P = 0.022) in the IVIG group.IVIG therapy can not only result in lower in-hospital mortality and superior recovery of left ventricular function in patients with acute myocarditis, but also increase the survival rate of AFM patients. The present study provides some supportive evidence for IVIG therapy in acute myocarditis patients.
