Abstract
BACKGROUND Osteonecrosis of the jaw (ONJ) has a frequent adverse effect after the administration of nitrogenous bisphosphonates, as non-nitrogenous bisphosphonates are metabolized more rapidly and would produce this effect to a lesser extent. The objective of this study is to analyze the results obtained in the literature with the use of L-PRF in the treatment of ONJ through a systematic review and meta-analysis. MATERIAL AND METHODS Medline (via PubMed), Cochrane, Web of Science and Grey Literature Database was screened from which 10 were selected. RESULTS In the meta-analysis with full resolution, combining the use of L-PRF in the treatment of ONJ, a weighted proportion (PP) of 94.3% of complete resolution is obtained (95% CI: 91.2-97.4, p<0.001), with a low degree of heterogeneity, statistically significant (I2 = 29.02%; p<0.001). When analyzing the non-resolution data, a weighted proportion (PP) of 7.7% (95% CI: 3.6-11.9; p<0.001) was obtained with moderate heterogeneity (I2: 41.87%; p=0.112). In the meta-regression, no significant correlation was found between complete resolution and year of publication (intercept = 2.88, p=0.829). In consistency analysis no major changes in PP are identified when any of the studies are eliminated, demonstrating a high reliability in the combined results. CONCLUSION L-PRF alone or in combination with other therapies in treatment of ONJ achieved high percentages of complete lesion resolution (94.3%). In studies where L-PRF is combined with other therapies, and where the effectiveness of the other therapy alone is analyzed, L-PRF has been shown higher percentages of resolution.

Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association. 2023
Abstract
PURPOSE To evaluate the role of platelet-rich plasma (PRP) for adhesive capsulitis (AC) as compared to other injectables. METHODS A literature search was performed on PubMed and Embase online databases identifying articles evaluating injection therapy for the treatment of AC. Inclusion criteria included prospective studies comparing PRP against alternative injectables with a minimum 15 patients in each treatment arm and a minimum 12-week follow-up. Pain scores, range of motion, and function scores were the primary outcomes assessed. RESULTS Five articles met inclusion criteria comparing PRP to corticosteroid or saline injections. There were 157 patients treated with PRP with follow-up duration ranging from three to six months. All five studies demonstrated statistically significant improvement in pain scores, motion, and function scores for patients receiving PRP, corticosteroid, and saline injections. However, PRP was consistently superior on intergroup analyses in all but one study. In four studies, pain and function scores favored PRP over control at final follow-up (range in mean difference for VAS pain score: -2.2 - 0.69, n=5 and SPADI score: -50.5 - -4.0, n=3) while three studies found greater improvement in shoulder motion after PRP (range in mean difference for forward flexion: 0.7 - 34.3 degrees and external rotation -2.3 - 20.4 degrees, n=4). One study found no significant difference between PRP and corticosteroid injections, but noted results were comparable. CONCLUSIONS According to a limited number of prospective studies, PRP injections for AC is at least equivalent to corticosteroid or saline injections and often leads to improved pain, motion, and functional outcomes at 3-6-month follow-up. Given the small number of studies, with design heterogeneity, there is insufficient evidence to routinely recommend PRP for AC. However, the results are promising and do support considering PRP as an adjunct treatment option for AC, especially for patients refractory and/or averse to corticosteroids or alternative treatment modalities.

Wijaya JH, July J, Quintero-Consuegra M, Chadid DP
Journal of neuro-oncology. 2023
Abstract
PURPOSE During intracranial meningioma surgery, surgeons experience considerable blood loss. Tranexamic acid (TXA) is used to minimize blood loss in several neurosurgical settings. However, evidence and trials are lacking. Our objective is to establish the most recent evidence on TXA safety and efficacy in intracranial meningioma surgery. METHODOLOGY Based upon Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), the authors collected fully published English literature on the administration of tranexamic acid for patients undergoing intracranial meningioma surgery using the keywords ["tranexamic acid" and "meningioma"] and its synonyms from Cochrane Central Database, the WHO International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, and PubMed. The primary outcome of the current study was total blood loss. The secondary outcomes include individuals requiring blood transfusion, anesthesia duration, surgical duration, and complication rate. Each included studies' quality was assessed using the JADAD scale. RESULTS For qualitative and quantitative data synthesis, we included five RCTs (n = 321) with the mean age was 47.5 ± 11.9 years for the intervention group and 47.2 ± 11.9 years for the control group. Our meta-analysis showed that the administration of TXA is associated with decreased total blood loss of standardized mean difference (SMD) of -1.40 (95% CI [-2.49, -0.31]), anesthetic time SMD -0.36 (95% CI [-0.63, -0.09]), and blood transfusion requirements RR 0.58 (95% CI [0.34, 0.99]). CONCLUSIONS The current study showed that TXA was associated with reduced intraoperative blood loss and intra- and postoperative blood transfusion. However, the studies are small. More RCT studies with a greater sample size are favorable.

Indian journal of orthopaedics. 2023;57(1):33-43
Abstract
PURPOSE Although numerous systematic reviews and meta-analyses have established the efficacy of tranexamic acid (TXA) in hip fracture surgeries, the included studies in those reviews have included all types of surgical interventions ranging from fixation to arthroplasty. Hip hemiarthroplasty is usually indicated in the elderly patients with femoral neck fracture and these patients have associated severe comorbidities and cognitive impairment. These subsets of patients with femoral neck fracture needs appropriate perioperative care and judicious use of antifibrinolytics. There is no meta-analysis evaluating the safety and efficacy of intravenous TXA in these patients. METHODS Searches of PubMed, Embase and Cochrane Central Register of Controlled Trials databases revealed 102 studies on TXA in hip fracture surgeries. After screening, eight studies were found to be suitable for review. The primary objective of this meta-analysis was to compare blood transfusion rate between TXA vs. control in hip hemiarthroplasty. The secondary objectives were total blood loss, postoperative haemoglobin, surgical duration, length of hospital stay and side effects (VTE, readmission and 30 days mortality). RESULTS There were one RCT, one prospective cohort study and six retrospective studies. All studies recruited the elderly patients. Intravenous (IV) TXA administration resulted in significant reduction in requirement of blood transfusion (12.7% vs. 31.9%; OR 0.28; 95% CI 0.17-0.46; p < 00,001; I (2) = 73%). The TXA group had significantly decreased total blood loss (MD - 100.31; 95% CI - 153.79, - 46.83; p < 0.0002). The postoperative Hb in the TXA group was significantly higher than the control group (MD 0.53; 95% CI 0.35, 0.71; p < 0.00001). There was no significant difference in the incidences of VTE (0.97% vs. 0.73%, OR 1.27; p = 0.81; I (2) = 64%) and readmission rate (9.2% vs. 9.64%; OR 0.79; p = 0.54), but 30-d mortality rate was significantly lower in the TXA group (3.41% vs. 6.04%; OR 0.66; p = 0.03). CONCLUSIONS Intravenous TXA is efficacious in the reduction of blood loss and transfusion need in hip hemiarthroplasty surgery for hip fracture, without increased risk of VTE. The blood conservation protocol led to decreased 30 days mortality in these fragile elderly patients. LEVEL OF EVIDENCE III.

Sivakumar I, Arunachalam S, Mahmoud Buzayan M, Sharan J
Journal of oral biology and craniofacial research. 2023;13(1):57-66
Abstract
BACKGROUND Platelet-rich plasma is considered an effective modality to promote bone regeneration, improve hard and soft tissue healing in surgical procedures including sinus augmentation. However, the survival of dental implants in sinus augmented sites with platelet-rich plasma has shown equivocal results in recent studies. PURPOSE In this systematic review, data on dental implants' survival in sinus augmentation sites with platelet-rich plasma were examined. MATERIALS AND METHODS Randomized controlled trials on the topic with a minimum mean follow-up of 6 months with no language restriction were considered. Other study designs on the topic were excluded. Accordingly, relevant articles were searched in Clinicaltrials.gov, Cochrane databases, PubMed/Medline, and Scopus up to April 2021. Using the Cochrane risk of bias assessment tool, the listed studies' risk of bias was evaluated. From the included studies, the pertinent information was taken and pooled for qualitative and quantitative analysis using R software 4.1.1. RESULTS Six randomized controlled trials involving 188 patients who underwent sinus augmentation with and without platelet-rich plasma, and 781 implants were included for qualitative and quantitative analysis. Four hundred and eleven implants were placed in the intervention group (with platelet-rich plasma) and 370 implants were placed in the control group (without platelet-rich plasma). The pooled estimate (OR 0.84, 95% CI 0.37 to 1.91; I(2) = 0%) indicated that there was no statistically significant difference observed between the groups. The test for subgroup differences showed no statistically significant differences between the subgroups (p = 0.45) with no heterogeneity (I(2) = 0%). CONCLUSION The bias associated with selective reporting of outcome data was considered as some concern for bias. This systematic review revealed that the effect of platelet-rich plasma is uncertain on the survival of dental implants.

Abstract
BACKGROUND The last two decades have seen the reintroduction of tourniquets into guidelines for the management of acute limb trauma requiring hemorrhage control. Evidence supporting tourniquet application has demonstrated low complication rates in modern military settings involving rapid evacuation timeframes. It is unclear how these findings translate to patients who have prolonged transport times from injury in rural settings. This scoping review investigates the relationship between time and distance on metabolic complications, limb salvage and mortality following tourniquet use in civilian and military settings. METHODS A systematic search strategy was conducted using PubMed, Embase, and SafetyLit databases. Study characteristics, setting, mechanism of injury, prehospital time, tourniquet time, distance, limb salvage, metabolic response, mortality, and tourniquet removal details were extracted from eligible studies. Descriptive statistics were recorded, and studies were grouped by ischemia time (< 2 h, 2-4 h, or > 4 h). RESULTS The search identified 3103 studies, from which 86 studies were included in this scoping review. Of the 86 studies, 55 studies were primarily in civilian environments and 32 were based in military settings. One study included both settings. Blast injury was the most common mechanism of injury sustained by patients in military settings (72.8% [5968/8200]) followed by penetrating injury (23.5% [1926/8200]). In contrast, in civilian settings penetrating injury was the most common mechanism (47.7% [1633/3426]) followed by blunt injury (36.4% [1246/3426]). Tourniquet time was reported in 66/86 studies. Tourniquet time over four hours was associated with reduced limb salvage rates (57.1%) and higher mortality rates (7.1%) compared with a tourniquet time of less than two hours. The overall limb salvage and mortality rates were 69.6% and 6.7% respectively. Metabolic outcomes were reported in 28/86 studies with smaller sample sizes and inconsistencies in which parameters were reported. CONCLUSION This scoping review presents literature describing comparatively safe tourniquet application when used for less than two hours duration. However, there is limited research describing prolonged tourniquet application or when used for protracted distances, such that the impact of tourniquet release time on metabolic outcomes and complications remains unclear. Prospective studies utilizing the development of an international database to provide this dataset is required.

Advances in therapy. 2023
Abstract
INTRODUCTION The role of human albumin (HA) infusion in cirrhotic patients has been increasingly recognized. This paper aims to summarize the evidence from meta-analyses regarding HA infusion for the management of cirrhosis and its complications. METHODS A systematic search in the PubMed, EMBASE, and Cochrane library databases, and in reference lists was conducted. All relevant meta-analyses were identified and their findings were reviewed. The Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) checklist was used to evaluate the methodological quality and the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system to assess the quality of evidence for significant outcomes. RESULTS Among 300 papers initially identified, 18 meta-analyses have been included. Short- and long-term HA infusion at high doses decreased the mortality of patients with decompensated cirrhosis. In cirrhotic patients with ascites, long-term HA infusion reduced the recurrence of ascites, but not mortality. In cirrhotic patients undergoing large-volume paracentesis (LVP), HA infusion reduced the incidence of post-paracentesis circulatory dysfunction and hyponatremia, but not mortality or renal impairment. In cirrhotic patients with overt hepatic encephalopathy (HE), HA infusion improved the severity of overt HE, but not overall mortality. In cirrhotic patients with spontaneous bacterial peritonitis (SBP), but not those with non-SBP infections, HA infusion reduced the mortality and renal impairment. In cirrhotic patients with type-1 hepatorenal syndrome (HRS), an increment of 100 g in cumulative HA dose increased 1.15-fold survival, but not HRS reversal. In these meta-analyses, the quality of methodology was low or critically low, and that of the evidence was from very low to moderate. CONCLUSIONS Based on the limited evidence from these meta-analyses, HA infusion appears to be beneficial in cirrhotic patients with ascites, overt HE, and SBP and in those undergoing LVP, but not in those with non-SBP infections.

Journal of orthopaedic surgery and research. 2023;18(1):14
Abstract
OBJECTIVE To evaluate the efficacy and safety of tranexamic acid (TXA) in hemostasis in patients undergoing posterior lumbar interbody fusion (PLIF) by meta-analysis. METHODS This study was registered on the International Prospective Register of Systematic Reviews (PROSPERO) (ID: CRD42022354812). The databases PubMed, Cochrane Library, Web of Science, and Embase were searched for randomized controlled trial (RCT) papers on the use of TXA in patients with PLIF from database establishment to August 2022. Two researchers screened the literature, extracted data, evaluated the risk of bias of the included studies, recorded the authors, sample size, type of study design, and TXA dose of each study, and extracted the intraoperative blood loss, number of blood transfusions, total blood loss, drainage volume, operation time, and incidence of deep venous thrombosis in each study. Meta-analysis was performed using RevMan 5.4 software provided by Cochrane Library. RESULTS A total of 14 RCTs with a total of 1681 patients were included in this study, including 836 patients in the TXA group and 845 patients in the control group. The intraoperative blood loss [mean difference (MD) = - 125.97, 95% confidence interval (CI) (- 138.56, - 113.37), P < 0.0001] and less total blood loss [MD = - 204.28, 95% CI (- 227.38, - 181.18), P < 0.00001] in TXA group were lower than the control group. Statistical significance was also observed in postoperative drainage volume [MD = - 115.03, 95% CI (- 123.89, - 106.17), P < 0.00001], operation time [MD = - 8.10, 95% CI (- 14.49, - 1.71), P = 0.01], and blood transfusion rate [odds ratio (OR) = 0.30, 95% CI (0.23, 0.39), P < 0.00001]. However, there was no statistical difference observed in the incidence of deep venous thrombosis [OR = 0.83, 95% CI (0.56, 1.21), P = 0.33]. CONCLUSION The application of TXA in PLIF can reduce intraoperative blood loss, total blood loss, drainage volume, the incidence of transfusion events, and operation time without increasing the risk of deep venous thrombosis.

Management of secondary postpartum haemorrhage: A systematic review
Fox R, Aitken G, Mooney SS
European journal of obstetrics, gynecology, and reproductive biology. 2023;282:116-123
Abstract
Secondary postpartum haemorrhage is a significant cause of postnatal morbidity and admission to hospital. It can be managed medically, surgically or with interventional radiological techniques, however, there is limited evidence to inform the most appropriate use of these treatments. This review aimed to summarise the existing evidence and evaluate the effectiveness and safety of the management options available for secondary postpartum haemorrhage. MEDLINE, EMBASE, CENTRAL, SCOPUS, Clinicaltrials.gov and ICTRP were searched from conception to August 2021. Eligible studies described the management of participants with secondary postpartum haemorrhage occurring between 24 h and 12 weeks after a pregnancy of at least 20 weeks gestation. All treatment interventions were eligible. Outcomes included reduction of bleeding, hospital admissions, re-presentations to hospital, secondary surgical procedures, blood transfusions, adverse effects of treatment, surgical complications, hysterectomy, ICU admissions, severe morbidity and mortality. The protocol for this review was registered with PROSPERO (ID: CRD42021274146). Eleven studies, describing 834 participants, were eligible for inclusion. Five studies reported outcomes of a single intervention and six studies reported outcomes of more than one treatment modality. Assessed interventions included medical management, surgical procedures, and radiological techniques. Resolution of bleeding was seen in 8.2-84.6 % of participants following medical management, 89.3-100 % following surgical management and 87.5-100 % post transcatheter arterial embolisation. When considering only studies published in the last 30 years, these results are 71.9-73.7 %, 89.3-92.0 % and 87.5-100 % respectively. All included studies were small and retrospective observational in design with poor methodological quality leading to a serious or critical risk of bias. This review has highlighted the deficiencies in evidence for the management of secondary PPH. Future, well designed, prospective studies are needed to provide guidance to clinicians managing this condition.

Miller SE, Leonard SA, Meza PK, Ku S, Ren LY, Lyell DJ, Sultan P, Butwick A
Obstetrics and gynecology. 2023;141(1):49-58
Abstract
OBJECTIVE To evaluate red blood cell use during delivery in patients with placenta accreta spectrum. DATA SOURCES We searched MEDLINE, EMBASE, CINAHL, Cochrane Central, ClinicalTrials.gov, and Scopus for clinical trials and observational studies published between 2000 and 2021 in countries with developed economies. METHODS OF STUDY SELECTION Abstracts (n=4,275) and full-text studies (n=599) were identified and reviewed by two independent reviewers. Data on transfused red blood cells were included from studies reporting means and SDs, medians with interquartile ranges, or individual patient data. The primary outcome was the weighted mean number of units of red blood cells transfused per patient. Between-study heterogeneity was assessed with an I2 statistic. Secondary analyses included red blood cell usage by placenta accreta subtype. TABULATION, INTEGRATION, AND RESULTS Of the 599 full-text studies identified, 20 met criteria for inclusion in the systematic review, comprising 1,091 cases of placenta accreta spectrum. The number of units of red blood cells transfused was inconsistently described across studies, with five studies (25.0%) reporting means, 11 (55.0%) reporting medians, and four (20.0%) reporting individual patient data. The weighted mean number of units transfused was 5.19 (95% CI 4.12-6.26) per patient. Heterogeneity was high across studies (I2=91%). In a sensitivity analysis of five studies reporting mean data, the mean number of units transfused was 6.61 (95% CI 4.73-8.48; n=220 patients). Further quantification of units transfused by placenta accreta subtype was limited due to methodologic inconsistencies between studies and small cohort sizes. CONCLUSION Based on the upper limit of the CI in our main analysis and the high study heterogeneity, we recommend that a minimum of 6 units of red blood cells be available before delivery for patients with placenta accreta spectrum. These findings may inform future guidelines for predelivery blood ordering and transfusion support. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42021240993.
