Meta-Analysis Review
Stroke and traumatic brain injury (TBI) are the critical public health and socioeconomic problems throughout the world. At present, citicoline is used as a coadjuvant for the management of acute ischemic stroke (AIS) and TBI in various countries. This systemic review analyzes the beneficial role of citicoline in AIS and TBI. This systemic review is based on "PubMed" and "Science Direct" search results for citicoline role in stroke and TBI. In this systemic review, we included 12 human trials. A meta-analysis was performed on the basis of neurological evaluation, functional evaluation and Glasgow outcome scale, domestic adaptation evaluation outcomes, and cognitive outcome individually. In neurological evaluation, domestic adaptation evaluation, and cognitive outcomes, there was no significant difference in both the citicoline and placebo groups (odds ratio [OR] = 1.04 [0.9-1.2, = 0.583]; OR = 1.1 [0.94-1.27, = 0.209]; OR = 0.953 [0.75-1.2, = 0.691]). In evaluation of functional outcomes, there was significant difference in both groups and OR was 1.18 (1.04-1.34, = 0.01). Functional outcomes were significantly improved by citicoline, but the positive role of this drug in neurological recovery, domestic adaptation, and cognitive outcomes is still a topic of discussion for future.

Meta-Analysis Review
Poly(adenosine diphosphate-ribose) polymerase inhibitor combinations in first-line metastatic castrate-resistant prostate cancer setting: a systematic review and meta-analysis.
OBJECTIVES
To compare radiographic progression-free survival (rPFS), overall survival (OS), and treatment-emergent adverse events (TEAEs) among patients with metastatic castrate-resistant prostate cancer (mCRPC) receiving a combination of first-line poly(adenosine diphosphate-ribose) polymerase inhibitors (PARPi) plus androgen receptor axis-targeted agents (ARAT) vs placebo/ARAT.
MATERIALS AND METHODS
We conducted a systematic review/meta-analysis of all published Phase III randomised controlled trials using EMBASE, MEDLINE, and Cochrane (inception until 6 June 2023). Published full-text manuscripts and conference abstracts were inclusion eligible. Study selection/data extraction were independently performed by two authors. The Cochrane Risk-of-Bias 2 Tool was used, and certainty of evidence assessed using the Grading of Recommendations, Assessment, Development, and Evaluations framework. Pooled hazard ratios (HRs) and relative risks, with corresponding confidence intervals (CIs), were generated using random-effects models.
RESULTS
Three trials were identified: PROpel, MAGNITUDE, and TALAPRO-2. Compared to placebo/ARAT, the PARPi/ARAT combination was associated with a 35% rPFS improvement in the overall cohort (HR 0.65, 95% CI 0.56-0.76), with 68%, 45%, and 26% improvements in the BReast CAncer gene 1/gene 2 (BRCA1/2)-mutated (BRCA1/2m; P < 0.001), homologous recombination repair-mutated (HRRm; P < 0.001), and non-HRRm cohorts (P = 0.003), respectively. OS data maturity ranged from 31% to 48%, with overall cohort OS data unavailable from MAGNITUDE. The PROpel/TALAPRO-2 pooled analysis demonstrated a 16% OS improvement in the overall cohort (HR 0.84, 95 CI 0.72-0.98; P = 0.02). OS in the HRRm (HR 0.76, 95% CI 0.61-0.95) and the BRCA1/2m cohorts (HR 0.53, 95% CI 0.18-1.56) were improved, with a higher effect magnitude compared to the overall cohort. This combination was associated with a 45% relative risk increase in Grade ≥3 TEAEs, including 6.22-fold for Grade ≥3 anaemia (31.9% vs 4.9%).
CONCLUSIONS
The addition of PARPi to ARAT in the first-line mCRPC setting is associated with rPFS benefits across subgroups, with the greatest magnitude of benefit in BRCA1/2m patients. OS benefits remain inconsistent irrespective of HRRm status, with significant increases in Grade ≥3 TEAEs, particularly anaemia. Currently, we suggest this combined approach be selectively offered to HRRm patients, preferentially BRCA1/2m.

Meta-Analysis Review
OBJECTIVES
To assess the effectiveness and safety of Chinese herbal medicine (CHM) for the treatment of aspirin resistance (AR).
METHODS
A comprehensive research of seven electronic databases was performed for comparative studies evaluating CHM for AR. Two authors independently extracted data and assessed the methodological quality of the included trials using the Cochrane risk of bias tool. Data wasere synthesized by using RevMan 5.3 software. (PROSPERO Registration #CRD42015020182).
RESULTS
18 randomized controlled trials (RCTs) involving 1,460 patients were included. 15 RCTs reported significant difference in the reduction of platelet aggregation rate (PAR) induced by adenosine diphosphate (ADP) (P<0.05), and 11 reported significant effect of CHM plus aspirin to reduce PAR induced by arachidonic acid (AA) (P<0.05) compared with aspirin 100mg/d treatment. The pooling data of 3 RCTs showed the thromboxane B2 (TXB2) in patients with CHM plus aspirin versus aspirin were significantly reduced (Random Effect model (RE), Standard Deviation (SD) = -95.93, 95% Confidential Interval (CI)[-118.25,-73.61], P<0.00001). Subgroup analysis showed that TXB2 (Fixed Effect model (FE), SD = -89.23, 95%CI[-121.96,-56.49], P<0.00001) had significant difference in Tongxinluo capsule plus aspirin versus aspirin. 2 RCTs reported the clinical effective rate, and the meta-analysis result showed a significant difference in intervention and control group (FE, Relative Risk (RR) = 1.67, 95%CI[1.15, 2.42], P = 0.007<0.05). In 4 trials, CHM plus aspirin had better effects of reducing the reoccurrence of cerebral infarction than aspirin (FE, RR = 0.24, 95%CI [0.11, 0.49], P<0.0001). And one trial showed that CHM plus aspirin could decrease the National Institutes of Health Stroke Scale (NHISS) score (P<0.05) and increase the Barthel Index (BI) score (P<0.05). 4 trials stated that there were no adverse effects occurred in intervention group, and analysis showed significant difference of CHM or CHM plus aspirin in reducing the occurrence of adverse events (FE, RR = 0.22, 95%CI[0.13, 0.39], P<0.00001). 5 trials claimed that the CHM monotherapy and CHM adjunctive therapy for AR did not add the risk of bleeding (FE, RR = 0.50, 95%CI[0.20, 1.22], P = 0.13>0.05).
CONCLUSIONS
CHM may be effective and safe as an alternative and collaborative therapy for AR. However, the current evidence and potential promising findings should be interpreted with caution due to poor and varying methodological quality of included studies and the heterogeneity of interventions. Thus, further exploration of this strategy with adequately powered RCTs is warranted.

PURPOSE
Glaucoma is a leading cause of irreversible blindness worldwide. Retinal ganglion cells (RGC), the neurons that connect the eyes to the brain, specifically die in glaucoma, leading to blindness. Elevated intraocular pressure (IOP) is the only modifiable risk factor, however, many patients progress despite excellent IOP control. Thus, alternative treatment strategies to prevent glaucoma progression are an unmet need. Citicoline has demonstrated neuroprotective properties in central neurodegenerative diseases. However, conclusive evidence of the effect of citicoline on glaucoma progression is missing. This systematic review investigates first-time the therapeutic potential of citicoline in glaucoma patients.
METHODS
The present study was conducted according to the PRISMA 2020 statement. PubMed, Web of Science, Google Scholar, and Embase were accessed in July 2023 to identify all clinical studies investigating the efficacy of citicoline on IOP, the mean deviation of the 24-2 visual field testing (MD 24-2), retinal nerve fibre layer (RNFL), and the pattern electroretinogram (PERG) P50-N95 amplitude in glaucoma patients. The risk of bias was assessed using the Review Manager 5.3 software (The Nordic Cochrane Collaboration, Copenhagen) and the Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I) tool.
RESULTS
Ten studies were eligible for this systematic review, including 424 patients. The mean length of the follow-up was 12.1 ± 11.6 months. The overall risk of bias was low to moderate. The mean age of the patients was 56.7 years. There were no significant differences in the IOP, MD 24-2, RNFL, or PERG P50-N95 amplitude between patients receiving citicoline and the control group. There was no improvement from baseline to the last follow-up in IOP, MD 24-2, RNFL, or PERG P50-N95 amplitude.
CONCLUSION
There is a lack of sufficient evidence to support that citicoline slows the progression of glaucoma.

Review
UNLABELLED
Traumatic brain injury is associated with coagulopathy that increases mortality risk. Viscoelastic hemostatic assays such as thromboelastography (Haemonetics SA, Signy, Switzerland) provide rapid coagulopathy assessment and may be particularly useful for goal-directed treatment of traumatic brain injury patients. We conducted a systematic review to assess thromboelastography in the evaluation and management of coagulopathy in traumatic brain injury patients.
DATA SOURCES
MEDLINE, PubMed Central, Embase, and CENTRAL.
STUDY SELECTION
Clinical studies of adult patients with traumatic brain injury (isolated or polytrauma) who were assessed by either standard thromboelastography or thromboelastography with platelet mapping plus either conventional coagulation assays or platelet function assays from January 1999 to June 2021.
DATA EXTRACTION
Demographics, injury mechanism and severity, diagnostic, laboratory data, therapies, and outcome data were extracted for analysis and comparison.
DATA SYNTHESIS
Database search revealed 1,169 sources; eight additional articles were identified by the authors. After review, 31 publications were used for qualitative analysis, and of these, 16 were used for quantitative analysis. Qualitative and quantitative analysis found unique patterns of thromboelastography and thromboelastography with platelet mapping parameters in traumatic brain injury patients. Patterns were distinct compared with healthy controls, nontraumatic brain injury trauma patients, and traumatic brain injury subpopulations including those with severe traumatic brain injury or penetrating traumatic brain injury. Abnormal thromboelastography K-time and adenosine diphosphate % inhibition on thromboelastography with platelet mapping are associated with decreased survival after traumatic brain injury. Subgroup meta-analysis of severe traumatic brain injury patients from two randomized controlled trials demonstrated improved survival when using a viscoelastic hemostatic assay-guided resuscitation strategy (odds ratio, 0.39; 95% CI, 0.17-0.91; = 0.030).
CONCLUSIONS
Thromboelastography and thromboelastography with platelet mapping characterize coagulopathy patterns in traumatic brain injury patients. Abnormal thromboelastography profiles are associated with poor outcomes. Conversely, treatment protocols designed to normalize abnormal parameters may be associated with improved traumatic brain injury patient outcomes. Current quality of evidence in this population is low; so future efforts should evaluate viscoelastic hemostatic assay-guided hemostatic resuscitation in larger numbers of traumatic brain injury patients with specific focus on those with traumatic brain injury-associated coagulopathy.

Meta-Analysis Review
: To identify the most frequently reported predictive factors for the persistency of pregnancy-related pelvic girdle pain (PPGP) at 3-6 months after childbirth in women with PPGP alone or PPGP in association with pregnancy-related lower back pain (PLBP). : Eligibility criteria: Two authors independently selected studies excluding PPGP determined by a specific, traumatic, gynecological/urological cause or isolated PLBP and studies that did not include the presence/absence of PPGP as the the primary outcome. We, instead, included studies with an initial assessment in pregnancy (within 1 month of delivery) and with a follow-up of at least 3 months after delivery. : The research was performed using the databases of Medline, Cochrane, Pedro, Scopus, Web of Science and Cinahl from December 2018 to January 2022, following the indications of the PRISMA statement 2021 and the MOOSE checklist. It includes observational cohort studies in which data were often collected through prospective questionnaires (all in English). : Two independent authors performed evaluations of the risk of bias (ROB) using the quality in prognostic studies (QUIPS) tool. : An in-depth qualitative analysis was conducted because, due to a high degree of heterogeneity in the data collection of the included studies and a lack of raw data suitable for quantitative analysis, it was not possible to carry out the originally planned meta-analyses for the subgroups. : The research process led to the inclusion of 10 articles which were evaluated using the QUIPS tool: 5 studies were evaluated as low ROB and 5 were evaluated as moderate ROB. High levels of pain in pregnancy, a large number of positive provocation tests, a history of lower back pain and lumbo-pelvic pain, high levels of disability in pregnancy, neurotic behavior and high levels of fear-avoidance belief were identified as strong predictors of long-term PPGP, while there was weak or contradictory evidence regarding predictions of emotional distress, catastrophizing and sleep disturbances. : The impossibility of carrying out the meta-analysis by subgroups suggests the need for further research with greater methodological rigor in the acquisition of measures based on an already existing PPGP core predictors/outcome sets.

Review
BACKGROUND
Platelet-rich plasma (PRP) has wide applications in orthopaedic care. Its beneficial effects are attributed to the growth factor profile from the platelet secretome. In theory, these effects would be diminished by medications that inhibit platelet activation and/or the subsequent release of growth factors.
PURPOSE
To determine whether commonly used antiplatelets, nonsteroidal anti-inflammatory drugs (NSAIDs), or anticoagulant medications affect platelet growth factor release in PRP.
STUDY DESIGN
Systematic review; Level of evidence, 2.
METHOD
A systematic review of the literature related to antiplatelet, anti-inflammatory, and anticoagulant drugs was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We used the Downs and Black objective quality scoring system. The literature search consisted of PubMed and Cochrane Library databases. Search terms consisted of 1 item selected from "platelet-rich plasma," "platelet-derived growth factor," and "platelet-rich plasma AND growth factor" combined with 1 item from "antiplatelet," "aspirin," "anticoagulant," and "NSAID." Only studies published within the past 25 years were included.
RESULTS
A total of 15 studies met the inclusion criteria: 7 studies detected no significant decrease in growth factors or mitogenesis, whereas 6 detected a decrease with antiplatelet agents, 1 detected mixed results with an antiplatelet agent, and 1 had mixed results with an antiplatelet agent/vasodilator. In terms of PRP activation, all 3 studies assessing collagen, the 2 studies analyzing adenosine diphosphate alone, and the 1 study investigating arachidonic acid found a decrease in growth factor concentration.
CONCLUSION
Antiplatelet medications may decrease the growth factor release profile in a cyclooxygenase 1- and cyclooxygenase 2-dependent manner. Eight of 15 studies found a decrease in growth factors or mitogenesis. However, more studies are needed to comprehensively understand antiplatelet effects on the PRP secretome.

Review
INTRODUCTION
Currently, the basis of acute coronary syndrome (ACS) therapy is dual antiplatelet therapy (DAPT) with Aspirin as a nonsteroidal anti-inflammatory drug and clopidogrel as adenosine diphosphate receptor antagonists. Therefore, the aim of the present systematic review is to answer that should DAPT with Aspirin and clopidogrel be continued until coronary artery bypass grafting (CABG) in patients who have ACS?
METHODS
The search for relevant studies in the present meta-analysis is based on three approaches: A) systematic searches in electronic databases, B) manual searches in Google and Google Scholar, and C) screening of bibliography of related original and review articles. The endpoints included mortality rate, myocardial infarction (MI), cerebrovascular accident (CVA), reoperation, re-exploration, other cardiac events, renal failure, length of ICU and hospital stay, chest tube drainage and blood product transfusion after CABG.
RESULTS
After the initial screening, 41 articles were studied in detail, and finally the data of 15 studies were included in the meta-analysis. DAPT before CABG in patients with ACS does not increase the rate of mortality, CVA, renal failure, MI, and other cardiac events, but increases reoperation, re-exploration, length of ICU, and hospital stay. Chest tube drainage and blood product transfusion rate significantly increased in the DAPT group compared to the control group (non-antiplatelet or Aspirin alone). Increase in chest tube drainage and blood product transfusion rate indicates an increase in bleeding, so increase in reoperation, re-exploration to control bleeding, and, subsequently, increase in the length of ICU and hospital stay are expected.
CONCLUSIONS
DAPT with Aspirin and clopidogrel before CABG in patients with ACS does not increase the rate of mortality, CVA, renal failure, MI, and other cardiac events despite more bleedings, and it may be suggested before CABG for better graft patency.

Review
BACKGROUND
The presence of an outer shell has been recently described as a common feature of acute ischemic stroke (AIS) thrombi. We performed a systematic review of the current literature on shell genesis, structure, and clinical significance.
METHODS
Following PRISMA guidelines, we searched Ovid Cochrane Central Register of Controlled Trials, Embase, Medline, Scopus, and Web of Science for studies reporting the composition and structure of AIS thrombi and clot analogs. Identified studies were added to Covidence software for primary screening. Two reviewers independently screened titles and abstracts followed by full-text screening.
RESULTS
From 1290 identified studies, 10 were included in this review. Studies using histology/immunohistochemistry/immunofluorescence described fibrin, platelets, von Willebrand factor, and neutrophil extracellular traps as the main components of the shell. Scanning electron microscopy demonstrated a dense, compact fibrin/platelet-rich shell, and a core rich in polyhedrocytes. Microfluidics studies identified highly activated P-selectin-positive platelets and fibrin forming the core while secondary agonists adenosine diphosphate and thromboxane, along with loosely packed P-selectin-negative platelets constituted the shell.
CONCLUSIONS
The composition, compaction, and integrity of the shell may impact thrombolysis and revascularization outcomes. The preponderance of studies supported this conclusion.

Review
Cembranoids and labdanes are two important types of diterpenes in tobacco (Nicotiana genus) that are predominantly found in the leaf and flower glandular trichome secretions. This is the first systematic review of the biosynthesis, chemical structures, bioactivities, and utilisation values of cembranoid and labdane diterpenes in tobacco. A total of 131 natural cembranoid diterpenes have been reported in tobacco since 1962; these were summarised and classified according to their chemical structure characteristics as isopropyl cembranoids (1-88), seco-cembranoids (89-103), chain cembranoids (104-123), and polycyclic cembranoids (124-131). Forty natural labdane diterpenes reported since 1961 were also summarised and divided into epoxy side chain labdanes (132-150) and epoxy-free side chain labdanes (151-171). Tobacco cembranoid and labdane diterpenes are both formed via the methylerythritol 4-phosphate pathway and are synthesised from geranylgeranyl diphosphate. Their biosynthetic pathways and the four key enzymes (cembratrienol synthase, cytochrome P450 hydroxylase, copalyl diphosphate synthase, and Z-abienol cyclase) that affect their biosynthesis have been described in detail. A systematic summary of the bioactivity and utilisation values of the cembranoid and labdane diterpenes is also provided. The agricultural bioactivities associated with cembranoid and labdane diterpenes include antimicrobial and insecticidal activities as well as induced resistance, while the medical bioactivities include cytotoxic and neuroprotective activities. Further research into the cembranoid and labdane diterpenes will help to promote their development and utilisation as plant-derived pesticides and medicines.
