Meta-Analysis Review
BACKGROUND
Breast cancer (BC) is a common malignant tumor. Apatinib in combination with other treatments has been used for BC; however, its safety and efficacy are not well-known. Therefore, this meta-analysis was performed to assess the efficacy and safety of apatinib in the treatment of BC.
METHODS
Studies comparing the effects of apatinib-based therapy versus control among BC patients were included. On January 21, 2022, a systematic search was performed in 9 databases. The risk ratio (RR) with 95% confidence interval (CI) was used to estimate efficacy and safety. The I square value (I) was used to assess heterogeneity. A leave-one-out sensitivity analysis was also conducted. Publication bias was assessed by funnel plots and Egger's and Begg's tests.
RESULTS
A total of 31 studies including 2,258 BC patients were included. The results showed that apatinib group had a significant improvement in disease control rate (DCR, RR = 1.43, 95% CI = 1.35-1.52, I = 43.8%) and objective response rate (ORR, RR = 1.79, 95% CI = 1.51-2.13, I = 61.8%) compared to the control group. Except for hemorrhage, hypertension, and hand-foot syndrome, the adverse events were similar between apatinib group and control group. Subgroup analyses found statistically significant differences in DCR in all subgroups except for apatinib combined with radiation therapy and with paclitaxel liposome plus S1. For ORR, there were statistically significant differences in all subgroups except for the radiation therapy, and apatinib monotherapy subgroups.
CONCLUSIONS
Our study shown apatinib showed good efficacy and acceptable safety in the treatment of BC patients. More high-quality randomized controlled trials from different regions and countries are needed to confirm our findings.

Review
Cigarette smoking is often initiated during adolescence and an earlier age of onset is associated with worse health outcomes later in life. Paradoxically, the transition towards adulthood also marks the potential for recovery, as the majority of adolescents are able to quit smoking when adulthood emerges. This systematic review aimed to evaluate the evidence from both human and animal studies for the differential impact of adolescent versus adult repeated and long-term tobacco and nicotine exposure on cognitive and brain outcomes. The limited human studies and more extensive yet heterogeneous animal studies, provide preliminary evidence of heightened fear learning, anxiety-related behaviour, reward processing, nicotinic acetylcholinergic receptors expression, dopamine expression and serotonin functioning after adolescent compared to adult exposure. Effects of nicotine or tobacco use on impulsivity were comparable across age groups. These findings provide novel insights into the mechanisms underlying adolescents' vulnerability to tobacco and nicotine. Future research is needed to translate animal to human findings, with a focus on directly linking a broader spectrum of brain and behavioural outcomes.

Comparative Study Meta-Analysis Review
INTRODUCTION
Thienopyridines are a class of antiplatelet drugs widely used in cardiovascular disease prevention and treatment. A recent concern has come to light regarding the safety of thienopyridines because of the possible risk of malignancy. We therefore performed a systematic review and meta-analysis to evaluate the association between thienopyridine exposure and malignancy.
METHODS
We searched the MEDLINE and EMBASE databases in March 2016 for studies that evaluated incident cancer and cancer mortality with and without exposure to thienopyridines. Relevant studies were identified, and data were extracted and analysed using random-effects meta-analysis.
RESULTS
A total of nine studies (six randomised controlled trials and three cohort studies) that included 282,084 participants were included. The cancer event rate with clopidogrel and prasugrel was 3.25% and 1.58% respectively. When compared with standard aspirin or placebo, thienopyridines are not significantly associated with cancer mortality and event rate (odds ratio [OR] 1.12, 95% confidence interval [CI] 0.80-1.56, n = 3; and OR 0.92, 95% CI 0.52-1.64, n = 2, respectively. Further analyses examining clopidogrel showed no significant association with cancer event rate or malignancy-related death. When comparing prasugrel with clopidogrel, no significant association was noted for cancer event rate (OR 1.10, 95% CI 0.89-1.37, n = 2]. Subanalyses according to cancer location showed that thienopyridines are not significantly associated with malignancy mortality and/or incidence.
CONCLUSIONS
Our results suggest that there is currently insufficient evidence to suggest that thienopyridine exposure is associated with an increased risk of cancer event rate or mortality.

Meta-Analysis Review
UNLABELLED
Zolpidem is a representative of non-benzodiazepine hypnotics. Recent epidemiologic studies have reported increased fracture risk in patients taking zolpidem, but the results have been inconsistent. The present meta-analysis shows that the use of zolpidem is associated with an increased risk of fractures.
PURPOSE
Previous studies have reported inconsistent findings regarding the association between the use of zolpidem and the risk of fractures. We performed a systematic literature review and meta-analysis to assess the association.
METHODS
We identified relevant studies by searching MEDLINE, EMBASE, Cochrane Library, and PsycINFO without language restrictions (until August 2014). Methodological quality was assessed based on the Newcastle-Ottawa Scale (NOS).
RESULTS
A total of 1,092,925 participants (129,148 fracture cases) were included from 9 studies (4 cohort, 4 case-control, and 1 case-crossover study). Overall, the use of zolpidem was associated with an increased risk of fracture (relative risk [RR] 1.92, 95 % CI 1.65-2.24; I (2) = 50.9 %). High-quality subgroups (cohort studies, high NOS score, adjusted for any confounder, or adjusted for osteoporosis) had higher RRs than the corresponding low-quality subgroups (high quality, 1.94-2.76; low quality, 1.55-1.79). Of note, the risk for hip fracture was higher than that for fracture at any site (hip fracture, RR 2.80, 95 % CI 2.19-3.58; fracture at any site, RR 1.84, 95 % CI 1.67-2.03; P < 0.001).
CONCLUSIONS
The use of zolpidem may increase the risk of fractures. Clinicians should be cautious when prescribing zolpidem for patients at high risk of fracture.

Meta-Analysis Review
Hypertension is one of the major side effects of sorafenib, and reported incidences vary substantially among clinical trials. A systematic review was conducted using Medline, PubMed, Embase, and the Cochrane Library for all longitudinal studies to investigate the incidence and risk of hypertension events in cancer patients treated with sorafenib. A total of 14 randomized controlled trials and 39 prospective single-arm trials involving 13,555 patients were selected for the meta-analysis. The relative risk of all-grade and high-grade hypertension associated with sorafenib were 3.07 (95% confidence interval [CI], 2.05–4.60; P<.01) and 3.31 (95% CI, 2.21–4.95; P<.01), respectively. The overall incidence of sorafenib-induced all-grade and high-grade hypertension were 19.1% (95% CI, 15.8%–22.4%) and 4.3% (95% CI, 3.0%–5.5%), respectively. A significantly higher incidence of hypertension was noted in patients with renal cell carcinoma (RCC) compared with those with non-RCC malignancies (all-grade: 24.9% [95% CI, 19.7%–30.1%] vs 15.7%[95% CI, 12.1%–19.3%]; P<.05; high-grade:8.6% [95% CI, 6.0%–11.2%] vs 1.8% [95% CI, 0.9%–2.6%]; P<.05). The trials with median progression-free survival (PFS) longer than 5.3 months (mean PFS) demonstrated a significantly higher incidence of high-grade hypertension than trials with shorter PFS (6.3% [95% CI, 4.1%–8.5%] vs 2.6% [95% CI, 1.4%– 3.8%]; P<.05). Findings of the meta-analysis indicated a significantly high risk of sorafenib-induced hypertension. Patients with RCC have a significantly higher incidence of hypertension and the occurrence of hypertension may be associated with improved prognosis.

Meta-Analysis Review
Comparison of effectiveness and safety of lasmiditan and CGRP-antagonists for the acute treatment of migraine in adults: systematic review and network meta-analysis of randomised trials.
OBJECTIVE
To compare the outcomes associated with the use of lasmiditan, rimegepant, ubrogepant, and zavegepant for the acute management of migraine headaches.
METHODS
We searched four electronic databases from database inception to August 31, 2023, to identify randomized controlled trials (RCTs) that report efficacy and safety for the acute treatment of migraine. The risk of bias in the included RCTs was evaluated according to the Cochrane tool, and the certainty of evidence using the CINeMA approach. We conducted frequentist network meta-analyses (NMA) to summarise the evidence. Data were analyzed using R-4.3.1.
RESULTS
A total of 18 eligible studies including 10 different types of interventions with 22,429 migraine patients were included. NMA results showed that compared to ubrogepant (25 mg and 50 mg) and zavegepant, lasmiditan (100 mg and 200 mg) exhibits an elevated probability of achieving pain relief within a 2-hour interval. Similarly, relative to zavegepant, rimegepant (75 mg) and ubrogepant (50 mg and 100 mg) demonstrate an enhanced likelihood of sustaining pain relief over a 24-hour period. Furthermore, in contrast to ubrogepant (25 mg) and lasmiditan (50 mg), rimegepant (75 mg) presents a heightened probability of achieving freedom from photophobia within 2 h. Regarding safety, lasmiditan carries the highest risk of adverse events, which are associated with an increased incidence of adverse effects, including dizziness, somnolence, asthenia, paresthesia, and fatigue.
CONCLUSIONS
In this NMA, a spectrum of evidence ranging from very low to high levels underscores the favorable efficacy and tolerability of rimegepant 75 mg and ubrogepant 100 mg, positioning them as potential candidates for the acute management of migraine. Concurrently, lasmiditan (100 mg and 200 mg) exhibits notable efficacy, albeit accompanied by an increased susceptibility to adverse events. These findings should still be approached with caution, primarily due to the intrinsic limitations associated with indirect comparisons.

Meta-Analysis Review
BACKGROUND
Proton-pump inhibitors (PPIs) are the mainstay of treatment in erosive esophagitis (EE). An alternative to PPIs in EE is Vonoprazan, a potassium competitive acid blocker. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing vonoprazan to lansoprazole.
METHODS
Multiple databases searched through November 2022. Meta-analysis was performed to assess endoscopic healing at two, four and eight weeks, including for patients with severe EE (Los Angeles C/D). Serious adverse events (SAE) leading to drug discontinuation were assessed. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology.
RESULTS
Four RCTs with 2208 patients were included in the final analysis. Vonoprazan 20 mg once-daily was compared to lansoprazole 30 mg once-daily dosing. Among all patients, at two and eight weeks post-treatment, vonoprazan resulted in significantly higher rates of endoscopic healing as compared to lansoprazole, risk ratios (RR) 1.1, p<0.001 and RR 1.04, p=0.03. The same effect was not observed at four weeks, RR 1.03 (CI 0.99-1.06, I=0%) following therapy. Among patients with severe EE, vonoprazan resulted in higher rates of endoscopic healing at two weeks, RR 1.3 (1.2-1.4, I=47%), p=<0.001, at four weeks, RR 1.2 (1.1-1.3, I=36%), p=<0.001 and at eight weeks post-treatment, RR 1.1 (CI 1.03-1.3, I=79%), p=0.009. We found no significant difference in the overall pooled rate of SAE and pooled rate of adverse events leading to drug discontinuation. Finally, the overall certainty of evidence for our main summary estimates was rated as high (grade A).
CONCLUSION
Based on limited number of published non-inferiority RCTs, our analysis demonstrates that among patients with EE, vonoprazan 20 mg once-daily dosing achieves comparable and in those with severe EE, higher endoscopic healing rates as compared to lansoprazole 30 mg once-daily dosing. Both drugs have a comparable safety profile.

BACKGROUND
Over 1.1 billion people smoke worldwide. The alkaloid nicotine is a prominent and addictive component of tobacco. In addition to tumors and cardiovascular disorders, tobacco consumption is associated with a variety of chronic-inflammatory diseases. Although neutrophilic granulocytes (neutrophils) play a role in the pathogenesis of many of these diseases, the impact of nicotine on neutrophils has not been systematically reviewed so far.
OBJECTIVES
The aim of this systematic review was to evaluate the direct influence of nicotine on human neutrophil functions, specifically on cell death/damage, apoptosis, chemotaxis, general motility, adhesion molecule expression, eicosanoid synthesis, cytokine/chemokine expression, formation of neutrophil extracellular traps (NETs), phagocytosis, generation of reactive oxygen species (ROS), net antimicrobial activity, and enzyme release.
MATERIAL AND METHODS
This review was conducted according to the PRISMA guidelines. A literature search was performed in the databases NCBI Pubmed and Web of Science™ in February 2023. Inclusion criteria comprised English written research articles, showing studies on the direct impact of nicotine on specified human neutrophil functions.
RESULTS
Of the 532 originally identified articles, data from 34 articles were finally compiled after several evaluation steps. The considered studies highly varied in methodological aspects. While at high concentrations (>3 mmol/l) nicotine started to be cytotoxic to neutrophils, concentrations typically achieved in blood of smokers (in the nmol/l range) applied for long exposure times (24-72h) supported the survival of neutrophils. Smoking-relevant nicotine concentrations also increased the chemotaxis of neutrophils towards several chemoattractants, elevated their production of elastase, lipocalin-2, CXCL8, leukotriene B4 and prostaglandin E2, and reduced their integrin expression. Moreover, while nicotine impaired the neutrophil phagocytotic and anti-microbial activity, a range of studies demonstrated increased NET formation. However, conflicting effects were found on ROS generation, selectin expression and release of β-glucuronidase and myeloperoxidase.
CONCLUSION
Nicotine seems to support the presence in the tissue and the inflammatory and selected tissue-damaging activity of neutrophils and reduces their antimicrobial functions, suggesting a direct contribution of nicotine to the pathogenesis of chronic-inflammatory diseases via influencing the neutrophil biology.

EDUCATIONAL OBJECTIVES As a result of reading this article, physicians should be able to: 1. Recognize the high risk of postoperative venous thromboembolism (VTE) in patients undergoing major orthopedic surgery. 2. Distinguish the different pharmacological mechanisms of VTE prophylaxis drugs. 3. Delineate the advantages and disadvantages of each VTE prophylaxis drug. 4. Recognize that rivaroxaban is as efficacious as apixaban but can increase the risk of hemorrhage. Patients undergoing major orthopedic surgery are at high risk for developing postoperative venous thromboembolism (VTE). The authors analyzed the available evidence on the efficacy and safety of dabigatran, apixaban, and rivaroxaban vs low-molecular-weight heparins (LMWHs) as VTE prophylaxis in major orthopedic surgery. Outcomes evaluated included total VTE, deep venous thrombosis (DVT), pulmonary embolism (PE), death, and major bleeding. Rivaroxaban and apixaban are more efficacious than dabigatran and are as safe as dabigatran. Rivaroxaban is as efficacious as apixaban but can increase the risk of hemorrhage.

Review
BACKGROUND
Clopidogrel resistance is a well-described phenomenon that has been linked to adverse cardiovascular events in patients with coronary artery disease. The impact of clopidogrel resistance in patient outcomes after vascular and endovascular surgery is not well-established.
METHODS
Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, a literature review with the medical subject headings (MeSH) terms "(clopidogrel resistance) and (vascular)", "(clopidogrel resistance) and (vascular surgery)", "(clopidogrel resistance) and (endovascular)", and "(clopidogrel resistance) and (endovascular surgery)" was performed in PubMed and Cochrane databases, to identify all peer-reviewed studies performed on clopidogrel resistance in vascular and endovascular surgery. Studies written in the English language from inception to 2022 were included. Case reports, studies with limited information, nonhuman studies, and studies not pertaining to vascular or endovascular surgery were excluded from analysis. Each study was independently reviewed by 2 qualified researchers to assess eligibility.
RESULTS
Of the 691 studies identified through the MeSH strategy, 16 studies met the inclusion criteria and were reviewed and summarized. These studies focused on extracranial cerebrovascular disease (n = 5) and peripheral arterial disease (PAD, n = 11), encompassing a total of 1,716 patients. The prevalence of clopidogrel resistance ranged from 0% to 83.3%, depending on the diagnostic assay and cutoff values used. In cerebrovascular disease, clopidogrel resistance may be associated with cerebral embolization, ischemic neurologic events, and vascular-related mortality. In PAD, clopidogrel resistance has been linked to recurrent stent thrombosis, target lesion revascularization, amputation-free survival, and all-cause mortality.
CONCLUSIONS
This systematic review provides an up-to-date summary of clopidogrel resistance in vascular and endovascular surgery. The impact of clopidogrel resistance remains incompletely investigated, and future studies are needed to clarify the role of resistance testing in patients with vascular disease.
