Abstract
BACKGROUND The optimal duration of hemostatic compression post transradial access is controversial. Longer duration increases the risk of radial artery occlusion (RAO) while shorter duration increases the risk of access site bleeding or hematoma. As such, a target of 2 hours is typically used. Whether a shorter or longer duration is better is not known. METHODS A PubMed, EMBASE, and clinicaltrials.gov databases were searched for randomized clinical trials of different duration (<90 minutes, 90 minutes, 2 hours, and 2-4 hours) of hemostasis banding. The efficacy outcome was RAO, primary safety outcome was access site hematoma, and secondary safety outcome was access site rebleeding. Primary analysis compared the effect of various duration in reference to the 2 hours duration using a mixed treatment comparison meta-analysis. RESULTS Of the 10 randomized clinical trials included with 4911 patients, when compared to the 2-hour reference duration, there was a significantly higher risk of access site hematoma with 90 minutes (odds ratio, 2.39 [95% CI, 1.40-4.06]) and <90 minutes (odds ratio, 3.61 [95% CI, 1.79-7.29]) but not with the 2 to 4 hours duration. When compared with the 2-hour reference, there was no significant difference in access site rebleeding or RAO with shorter or longer duration but the point estimates favored longer duration for access site rebleeding and shorter duration for RAO. Duration of <90 minutes and 90 minutes ranked 1 and duration of 2 hours ranked 2 as the most efficacious duration whereas duration of 2 hours ranked 1 and 2 to 4 hours ranked 2 as the safest duration. CONCLUSIONS In patients undergoing transradial access for coronary angiography or intervention, a hemostasis duration of 2 hours offers the best balance for efficacy (prevention of RAO) and safety (prevention of access site hematoma/rebleeding).

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) are the standard treatment for patients with renal anemia to increase hemoglobin (Hb) levels and reduce the need for blood transfusions. However, treatments targeting high Hb levels require high doses of ESAs administered intravenously, which is associated with an elevated risk of adverse cardiovascular events. Furthermore, there have been some problems such as hemoglobin variability and low achievement of target hemoglobin due to the shorter half-lives of ESAs. Consequently, erythropoietin-promoting medications, such as hypoxia-inducible factor-prolyl hydroxylase (HIF-PH) inhibitors, have been developed. This study aimed to evaluate changes in the Treatment Satisfaction Questionnaire for Medicine version II (TSQM-II) domain scores relative to baseline in each trial, to assess patient satisfaction with molidustat versus darbepoetin alfa. METHODS This post-hoc analysis of two clinical trials compared treatment satisfaction with an HIF-PH inhibitor, molidustat, versus a standard ESA, darbepoetin alfa, as part of therapy in patients with non-dialysis chronic kidney disease (CKD) and renal anemia. RESULTS Exploratory outcome data using the TSQM-II showed that both arms in both trials had enhanced treatment satisfaction over the course of the study period, as well as improvements in most TSQM-II domains at week 24 of treatment. Molidustat was associated with convenience domain scores at multiple time points depending on the trial. More patients were highly satisfied with the convenience of molidustat than that of darbepoetin alfa. Patients treated with molidustat had increased global satisfaction domain scores compared with those treated with darbepoetin alfa; however, the differences in global satisfaction domain scores were not significant. CONCLUSION These patient-reported satisfaction outcomes support the use of molidustat as a patient-centered treatment option for CKD-related anemia.

Abstract
PURPOSE To evaluate the safety and efficacy of platelet-rich plasma (PRP) intra-articular injective treatments for ankle osteoarthritis (OA). METHODS A systematic literature search was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in PubMed, Scopus, Embase, Google Scholar, and the Cochrane library until May 2022. Both randomized and non-randomized studies were included with the assessment of the risk of bias. We recorded the participant's age, gender, type of PRP, injection volume, the kit used, and activating agent. We subsequently assessed the short-term and long-term efficacy of PRP using the functional scores and visual analog scale (VAS). RESULTS We included four studies with a total of 127 patients, with a mean age of 56.1 years. 47.2% were male (60/127), according to eligibility criteria. There were three cohort studies and one randomized controlled trial (RCT) study, and no study reported severe adverse events. All included studies used the Leukocyte-poor PRP. Short-term follow-up results suggested significant improvement of the American Orthopaedic Foot and Ankle Society (AOFAS) score in the PRP injection group compared to the control group (n = 87 patients; MD: 6.94 [95% CI: 3.59, 10.29]; P < 0.01). Consistently, there was a statistical difference in AOFAS score between PRP injection and control groups in the final follow-up (≥ 6 months) (n = 87 patients; MD: 9.63 [95% CI: 6.31, 12.94]; P < 0.01). Furthermore, we found a significant reduction in VAS scores in the PRP groups at both the short-term follow-up (n = 59 patients; MD, - 1.90 [95% CI, - 2.54, - 1.26]; P < 0.01) and the ≥ six months follow-up (n = 79 patients; MD, - 3.07 [95% CI, - 5.08, - 1.05]; P < 0.01). The improvement of AOFAS and VAS scores at ≥ six months follow-up reached the minimal clinically important difference (MCID). Nevertheless, the treatment effect of AOFAS and VAS scores offered by PRP at short-term follow-up did not exceed the MCID. Substantial heterogeneity was reported at the ≥ six months follow-up in VAS scores (I(2): 93%, P < 0.01). CONCLUSION This meta-analysis supports the safety of PRP intra-articular injection for ankle OA. The improvements of AOFAS and VAS scores in the PRP group at short-term follow-up do not exceed the MCID to be clinically significant. PRP injection provides significant improvement of AOFAS score and reduced pain at ≥ six months follow-up. The efficacy of PRP should be interpreted with caution regarding the high heterogeneity and the scarcity of available literature, which urges large-scale RCTs with longer follow-up to confirm the potential efficacy of PRP injection for ankle OA.

Journal of anesthesia. 2023;:1-14
Abstract
The aim of this review was to update evidence for benefit of convalescent plasma transfusion (CPT) in patients with coronavirus disease 2019 (COVID-19). Databases were searched for randomized controlled trials (RCT) comparing CPT plus standard treatment versus standard treatment only in adults with COVID-19. Primary outcome measures were mortality and need for invasive mechanical ventilation (IMV). Twenty-Six RCT involving 19,816 patients were included in meta-analysis for mortality. Quantitative synthesis showed no statistically significant benefit of adding CPT to standard treatment (RR = 0.97, 95% CI = 0.92 to 1.02) with unimportant heterogeneity (Q(25) = 26.48, p = .38, I(2) = 0.00%). Trim-and-fill-adjusted effect size was unimportantly changed and level of evidence was graded as high. Trial sequential analysis (TSA) indicated information size was adequate and CPT was futile. Seventeen trials involving 16,083 patients were included in meta-analysis for need of IMV. There was no statistically significant effect of CPT (RR = 1.02, 95% CI = 0.95 to 1.10) with unimportant heterogeneity (Q(16) = 9.43, p = .89, I(2) = 3.30%). Trim-and-fill-adjusted effect size was trivially changed and level of evidence was graded as high. TSA showed information size was adequate and indicated futility of CPT. It is concluded with high level of certainty that CPT added to standard treatment of COVID-19 is not associated with reduced mortality or need of IMV compared with standard treatment alone. In view of these findings, further trials on efficacy of CPT in COVID-19 patients are probably not needed.

Abstract
BACKGROUND Intracerebral hemorrhage (ICH) is a stroke with a high morbidity and mortality rate. Deferoxamine (DFX) is thought to be effective in treating Intracerebral Hemorrhage. In our study, we performed a meta-analysis to evaluate the treatment effects of DFX. METHODS We systematically searched PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, and Chinese Biomedical Literature Database in Jan 2022 for studies on DFX for ICH patients. Outcome measures included relative hematoma volume, relative edema volume, good neurological functional outcome and adverse events. Odds risk (OR) and weighted mean difference (WMD) were used to evaluate clinical outcomes. RESULTS After searching 636 articles, 4 RCTs, 2 NRCTs, and 1cohort study were included. We found that DFX was effective in hematoma absorption on day 7 after onset, but the difference was not significant on day 14. DFX could suppress edema expansion on days 3, 7, and 14 after onset. DFX did not contribute to better outcomes after 3 and 6 months when used the modified Rankin Scale and the Glasgow Outcome Scale to evaluate neurological prognosis. The pooled results showed no statistically significant difference in Serious adverse events between the experimental and control groups. CONCLUSIONS DFX could limit edema expansion on days 3, 7, and 14 after commencement and facilitate hematoma absorption at week 1 without significantly increasing the risk of adverse events, but it did not improve neurological prognosis.

Abstract
OBJECTIVES Corticosteroid (CS) injection is commonly used in partial-thickness rotator cuff tears to decrease pain. However, this could result in unwanted side effects, such as tendon rupture. Alternatively, platelet-rich plasma (PRP) injection is frequently used to treat tendinopathies because it enhances healing. This study aimed to compare the differences in tear size and functional scores between intralesional PRP and subacromial CS injections. METHODS Patients with symptomatic partial-thickness tears of the supraspinatus tendon who underwent conservative treatment for ≥ 3 months were enrolled. All patients underwent magnetic resonance imaging (MRI) to confirm the diagnosis. Fourteen and 15 patients were randomized to receive intralesional PRP and subacromial CS injections, respectively. Tears were measured in the coronal and sagittal planes. The patients underwent another MRI 6 months after the injection. Tear size was compared between the two MRI results. The American Shoulder and Elbow Surgeons Shoulder score (ASES) and Constant-Murley score (CMS) were also obtained. RESULTS The baseline data were similar between the groups. In the coronal plane, PRP and CS showed tear size reductions of 3.39 mm (P = 0.003) and 1.10 mm (P = 0.18), respectively. In the sagittal plane, PRP and CS showed tear size reductions of 2.97 mm (P = 0.001) and 0.76 mm (P = 0.29), respectively. Functional scores improved 6 months after injection in both groups, but PRP showed better functional scores than CS (P = 0.002 for ASES, P = 0.02 for CS). CONCLUSION Intralesional PRP injection can reduce the tear size in partial-thickness tears of the supraspinatus tendon. Subacromial steroid injection did not significantly affect the tear size. While CS improved functional scores compared with baseline, PRP resulted in better improvement 6 months post-injection. Trial registration Thai Clinical Trials Registry, TCTR20210428004.

BMJ open. 2023;13(3):e063554
Abstract
INTRODUCTION Acute gastrointestinal bleeding (GIB) is a life-threatening emergency with a critical economic burden. As a result of bleeding, anaemia often requires intravenous or oral iron supplementation. Elderly patients are even more prone to untoward outcomes after hospital discharge if iron supplementation is inefficient. There is a gap in current guidelines on which supplementation route clinicians should choose. We aim to investigate the effect of one dose of intravenous iron therapy versus 3-month oral iron administration on anaemia in an elderly population. METHODS AND ANALYSIS The FIERCE study is an open-label, randomised controlled, two-armed trial. At least 48 hours after the acute non-variceal GIB treatment, patients will be recruited in participating centres. A random sequence generator will allocate the participants to group A (intravenous ferric carboxymaltose, 1000 mg) or group B (oral ferrous sulfate (FS), ca. 200 mg every day) with an allocation ratio of 1:1 on the day of the planned discharge from the hospital. Randomisation will be stratified for participating centres and the need for transfusion within the same hospitalisation before recruitment to the trial. Quality of life assessment, functional measurement and laboratory tests will be performed at baseline, 1 and 3 months±7 days after enrolment to the trial. The primary endpoint is a composite endpoint, including all-cause mortality, anaemia-associated unplanned emergency visit and anaemia-associated unplanned hospital admission within 3 months of enrolment in the trial. ETHICS AND DISSEMINATION The study has been approved by the relevant organisation, the Scientific and Research Ethics Committee of the Hungarian Medical Research Council (46395-5/2021/EÜIG). We will disseminate our results to the medical community and will publish our results in peer-reviewed journals. TRIAL REGISTRATION The trial has been registered at ClinicalTrials.gov (NCT05060731).

Medicina (Kaunas, Lithuania). 2023;59(4)
Abstract
Background and Objectives: Recently, the clinical application of platelet-rich plasma (PRP) has gained popularity for the treatment of degenerative disc diseases. However, the regenerative effects and factors associated with treatment outcomes after intradiscal injection of PRP remain unknown. This study aimed to evaluate time-dependent changes in imaging findings related to intervertebral disc (IVD) degeneration and to identify factors associated with the outcomes of PRP injection therapy. Materials and Methods: A retrospective analysis of a previous randomized clinical trial of intradiscal injection of the releasate isolated from PRP (PRPr) in patients with discogenic low back pain (LBP) was performed. Radiographic parameters (segmental angulation and lumbar lordosis) and MRI phenotypes, including Modic changes, disc bulge, and high-intensity zones (HIZs), were evaluated at baseline and 6 and 12 months post-injection. Treatment outcomes were evaluated based on the degree of LBP and LBP-related disability at 12 months post-injection. Results: A total of 15 patients (mean age: 33.9 ± 9.5 years) were included in this study. Radiographic parameters showed no significant changes after the PRPr injection. There were no remarkable changes in the prevalence or type of MRI phenotype. Treatment outcomes were significantly improved after treatment; however, the number of targeted discs and the presence of posterior HIZs at baseline were significantly but negatively associated with treatment outcomes. Conclusions: Intradiscal injection of PRPr significantly improved LBP and LBP-related disability 12 months post-injection; however, patients with multiple target lesions or posterior HIZs at baseline were significantly associated with poor treatment outcomes.

Drug research. 2023
Abstract
PURPOSE This study was conducted to evaluate whether the efficacy and safety profile of recombinant human erythropoietin (rhEPO) manufactured by Daewoong Pharmaceutical Co., Ltd was similar to biological products approved by the drug safety regulatory authority. PATIENTS AND METHODS It was an open-label, randomized, comparative, parallel, multi-center study in hemodialysis patients with anemia. The reference product at an individualized dose 3 times a week was given in 4-8 weeks of titration period and hemoglobin (Hb) level was controlled to reach the range of 10-12 g/dL. Then, the subjects were randomly administered with reference or test product with the same dose regimen. The primary endpoints were to demonstrate the Hb level change between baseline and evaluation period in both treatment groups, while the secondary endpoints were the mean change in weekly dosage per kg body weight and the instability rate of Hb level during maintenance and evaluation period. The safety was evaluated based on the adverse events incidence. RESULTS There was no statistical difference in the change of Hb between test and reference (0.14 g/dL and 0.75 g/dL respectively, with p>0.05), also for the mean changes of weekly dosage between groups (1091.40 IU and 570.15 IU respectively, with p>0.05). The instability rate of Hb in both test and reference was not statistically significantly different as well (26 and 15% respectively, with p>0.05). CONCLUSION This study proves that the efficacy indicated by the change instability of Hb and safety indicated by adverse event incidence of Epodion and the reference product on chronic kidney disease were similar.

Journal of wrist surgery. 2023;12(2):135-142
Abstract
Background Platelet-rich plasma (PRP) has local anti-inflammatory actions, which is being used as a treatment in various tendinopathies. Purpose The aim of the study is to compare the clinical results of PRP injection and corticosteroid injection in the management of de Quervain's tenosynovitis (DQTSV). Patients and Methods In this prospective study, 60 patients of DQTSV, fulfilling the predefined inclusion and exclusion criteria, were randomised into two groups. In group 1 ( n = 30), patients received a single injection of autologous PRP and in group 2 ( n = 30) they received a single injection of corticosteroid (methylprednisolone). All patients were followed up at 1 month, 3 months, 6 months, and 1 year for evaluation by Finkelstein test, visual analogue scale (VAS), DASH (Disabilities of the Arm, Shoulder and Hand) score, and Modified Mayo Wrist score (MMWS). Results In both the groups improvement occurred in Finkelstein test, VAS score, DASH score, and MMWS which were found to be statistically significant at all points of follow-ups when compared to the pre-intervention values. Comparison of scores between the two groups did not show any statistical significance. No complications were reported in PRP group. Statistically significant complications ( p -value = 0.026) like subcutaneous fat atrophy, depigmentation, and temporary increase in pain were seen in eight patients in the corticosteroid group with an overall complication rate of 26.67%. Conclusion Both the modalities are equally effective in the management of DQTSV remittance. PRP is equally effective as corticosteroid in reducing symptoms of first dorsal compartment stenosing tenosynovitis. PRP may have a lower complication profile, however, this benefit should be weighed against the slight increase in cost and time of PRP preparation and injection. Level of Evidence Level 2, prospective comparative study.
