Aminobenzotriazole (ABT) is commonly used as a non-selective inhibitor of cytochrome P450 (CYP) enzymes to assign contributions of CYP versus non-CYP pathways to the metabolism of new chemical entities. Despite widespread use, a systematic review of the drug-drug interaction (DDI) potential for ABT has not been published nor have the implications for using it in plated hepatocyte models for low clearance reaction phenotyping. The goal being to investigate the utility of ABT as a pan-CYP inhibitor for reaction phenotyping of low clearance compounds by evaluating stability over the incubation period, inhibition potential against UGT and sulfotransferase enzymes, and interaction with nuclear receptors involved in the regulation of drug metabolizing enzymes and transporters. Induction potential for additional inhibitors used to ascribe fraction metabolism (f ), pathway including erythromycin, ketoconazole, azamulin, atipamezole, ZY12201, and quinidine was also investigated. ABT significantly inhibited the clearance of a non-selective UGT substrate 4-methylumbelliferone, with several UGTs shown to be inhibited using selective probe substrates in human hepatocytes and rUGTs. The inhibitors screened in the induction assay were shown to induce enzymes regulated through Aryl Hydrocarbon Receptor, Constitutive Androstane Receptor, and Pregnane X Receptor. Lastly, a case study identifying the mechanisms of a clinical DDI between Palbociclib and ARV-471 is provided as an example of the potential consequences of using ABT to derive f . This work demonstrates that ABT is not an ideal pan-CYP inhibitor for reaction phenotyping of low clearance compounds and establishes a workflow that can be used to enable robust characterization of other prospective inhibitors.

Meta-Analysis
BACKGROUND
Due to encouraging pre-clinical data and supportive observational studies, there has been growing interest in applying cardiovascular drugs (including aspirin, angiotensin-converting enzyme [ACE] inhibitors, statins, and metformin) approved to treat diseases such as hypertension, hyperlipidemia, and diabetes mellitus to the field of oncology. Moreover, given growing costs with cancer care, these medications have offered a potentially more affordable avenue to treat or prevent recurrence of cancer. We sought to investigate the anti-cancer effects of drugs repurposed from cardiology or anti-inflammatories to treat cancer. We specifically evaluated the following drug classes: HMG-CoA reductase inhibitors (statins), cyclo-oxygenase inhibitors, aspirin, metformin, and both angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors. We also included non-steroidal anti-inflammatory drugs (NSAIDs) because they exert a similar mechanism to aspirin by blocking prostaglandins and reducing inflammation that is thought to promote the development of cancer.
METHODS
We performed a systematic literature review using PubMed and Web of Science with search terms including "aspirin," "NSAID," "statin" (including specific statin drug names), "metformin," "ACE inhibitors," and "ARBs" (including specific anti-hypertensive drug names) in combination with "cancer." Searches were limited to human studies published between 2000 and 2023.
MAIN OUTCOMES AND MEASURES
The number and percentage of studies reported positive results and pooled estimates of overall survival, progression-free survival, response, and disease-free survival.
RESULTS
We reviewed 3094 titles and included 67 randomized clinical trials. The most common drugs that were tested were metformin (n = 21; 30.9%), celecoxib (n = 20; 29.4%), and simvastatin (n = 8; 11.8%). There was only one study that tested cardiac glycosides and none that studied ACE inhibitors. The most common tumor types were non-small-cell lung cancer (n = 19; 27.9%); breast (n = 8; 20.6%), colorectal (n = 7; 10.3%), and hepatocellular (n = 6; 8.8%). Most studies were conducted in a phase II trial (n = 38; 55.9%). Most studies were tested in metastatic cancers (n = 49; 72.1%) and in the first-line setting (n = 36; 521.9%). Four studies (5.9%) were stopped early because of difficulty with accrual. The majority of studies did not demonstrate an improvement in either progression-free survival (86.1% of studies testing progression-free survival) or in overall survival (94.3% of studies testing overall survival). Progression-free survival was improved in five studies (7.4%), and overall survival was improved in three studies (4.4%). Overall survival was significantly worse in two studies (3.8% of studies testing overall survival), and progression-free survival was worse in one study (2.8% of studies testing progression-free survival).
CONCLUSIONS AND RELEVANCE
Despite promising pre-clinical and population-based data, cardiovascular drugs and anti-inflammatory medications have overall not demonstrated benefit in the treatment or preventing recurrence of cancer. These findings may help guide future potential clinical trials involving these medications when applied in oncology.

European Journal of Anaesthesiology May 2024Open colectomy is still performed around the world and associated with significant postoperative pain.
BACKGROUND
Open colectomy is still performed around the world and associated with significant postoperative pain.
OBJECTIVES
Unpublished recommendations based on a systematic review were proposed by the PROcedure SPECific postoperative pain managemenT (PROSPECT) group in 2016. We aimed to update these recommendations by evaluating the available literature and develop recommendations for optimal pain management after open colectomy according to the PROSPECT methodology.
DESIGN AND DATA SOURCES
A systematic review using the PROSPECT methodology was undertaken. Randomised controlled trials and systematic reviews published in the English language from 2016 to 2022 assessing postoperative pain after open colectomy using analgesic, anaesthetic or surgical interventions were identified. The primary outcome included postoperative pain scores.
RESULTS
The previous 2016 review included data from 93 studies. Out of 842 additional eligible studies identified, 13 new studies were finally retrieved for analysis. Intra-operative and postoperative interventions that improved postoperative pain were paracetamol, epidural analgesia. When epidural is not feasible, intravenous lidocaine or bilateral TAP block or postoperative continuous pre-peritoneal infusion are recommended. Intra-operative and postoperative Cyclo-oxygenase (COX)-2 specific-inhibitors or non-steroidal anti-inflammatory drugs (NSAIDs) are recommended for colonic surgery.
CONCLUSIONS
The analgesic regimen for open colectomy should include intra-operative paracetamol and COX-2 specific inhibitors or NSAIDs (restricted to colonic surgery), epidural and continued postoperatively with opioids used as rescue analgesics. If epidural is not feasible, bilateral TAP block or IV lidocaine are recommended. Safety issues should be highlighted: local anaesthetics should not be administered by two different routes at the same time. Because of the risk of toxicity, careful dosing and monitoring are necessary.

Meta-Analysis Review
Parkinson's Disease (PD) is a common neurodegenerative disease which manifests with motor features, such as bradykinesia, resting tremor, rigidity, and postural instability. Using the non-invasive technique of saliva collection, we designed a systematic review to answer the question "Are salivary biomarkers reliable for the diagnosis of Parkinson's Disease?". Following inclusion and exclusion criteria, 30 studies were included in this systematic review (according to the PRISMA statement guidelines). Mostly proteins were reported as potential biomarkers in saliva. Based on meta-analysis, in PD patients, salivary levels of total alpha-synuclein were significantly decreased, and those of oligomeric alpha-synuclein were significantly increased. Also, according to pooled AUC, heme oxygenase-1 demonstrated significant predictive value for saliva-based PD diagnosis. In conclusion, some potential biomarkers, especially alpha-synuclein, can be altered in the saliva of PD patients, which could be reliably useful for early diagnosis of this neurodegenerative disease differentiating other synucleopathies.

Current Pharmaceutical Biotechnology Feb 2024Epilepsy is one of the most common in all age groups and disabling neurologic disorders around the world.
BACKGROUND
Epilepsy is one of the most common in all age groups and disabling neurologic disorders around the world.
OBJECTIVES
This systematic review was to explore whether berberine (BBR) has any anti-seizure or anti-epileptic effects and also reviewed this possible mechanism.
METHODS
The EMBASE, Scopus, Cochrane Library, PubMed, and Web of Science databases were searched before Sep 2023. All types of studies that investigated the effects of BBR on epilepsy or chemical-induced seizures were eligible for inclusion. Two authors independently evaluated and reviewed titles/abstracts to identify publications for potential eligibility, and a third team member resolved discrepancies. Data were extracted in an Excel form, and the outcomes were discussed.
RESULTS
BBR showed its neuroprotective properties by reducing oxidative stress, neuroinflammation, and anti-apoptosis effects. It also increases brain-derived neurotrophic factor (BDNF) release and reduces transforming growth factor-beta (TGF-β1) and hypoxia-inducible factor 1α (HIF-1α). BBR by increasing scavenging reactive oxygen species (ROS), nuclear factor erythroid 2-related factor 2 (Nrf2), endogenous antioxidant enzymes, heme oxygenase-1 (HO-1), and inhibition of lipid peroxidation insert its antioxidant activity. Moreover, BBR showed antiinflammatory activity by reducing Interleukin (IL)-1β, IL-6, and tumor necrosis factor-alpha (TNF-α) levels and through inhibiting cyclooxygenase-2 (COX-2), and including nuclear factor κB (NF-κB). In addition, it modulated c-fos expression and neuronal excitability in the brain.
CONCLUSION
BBR indicated promising anti-seizure effects with remarkable antioxidant, antiinflammatory, anti-apoptotic, and neuroprotective activity. Future studies should be based on well-designed clinical trial studies that are integrated with new methods related to increasing bioavailability.

Meta-Analysis Review
Cardiovascular and renal safety outcomes of hypoxia-inducible factor prolyl-hydroxylase inhibitor roxadustat for anemia patients with chronic kidney disease: a systematic review and meta-analysis.
This systematic review and meta-analysis were conducted to evaluate the cardiac and kidney-related adverse effects of roxadustat for the treatment of anemia in CKD patients. 18 trials with a total of 8806 participants were identified for analysis. We employed a fixed-effects model for analysis. The pooled result revealed no significant difference in the risk of occurrence of cardiac disorders when comparing CKD patients receiving roxadustat with the placebo (RR = 1.049; CI [0.918 to 1.200]) or ESA (RR = 1.066; CI [0.919 to 1.235]), in both dialysis-dependent (DD) (RR = 1.094; CI [0.925 to 1.293]) or non-dialysis-dependent (NDD) (RR = 1.036; CI [0.916 to 1.171]) CKD patients. No significant difference was observed in the risk of kidney-related adverse events when comparing roxadustat with the placebo (RR = 1.088; CI [0.980 to 1.209]) or ESA (RR = 0.968; CI [0.831 to 1.152]), in DD (RR = 2.649; CI [0.201 to 34.981]) or NDD (RR = 1.053; CI [0.965 to 1.149]) CKD patients. A high risk of hyperkalemia was observed in the roxadustat group in DD (RR = 0.939; CI [0.898 to 0.981]). Incidence of hypertension was higher in the roxadustat for NDD patients (RR = 1.198; CI [1.042 to 1.377]), or compared to the placebo (RR = 1.374; CI [1.153 to 1.638]). In summary, the risk of cardiac or kidney-related events observed in the roxadustat was not significantly increase whether in DD or NDD patients. However, attention must be paid to the occurrence of hyperkalemia for DD patients and hypertension in NDD patients using roxadustat.

Meta-Analysis
PURPOSE
This study aimed to investigate the association between cytochrome P450 (CYP) 3A4*22 and cytochrome P450 oxidoreductase (POR)*28 variations and the pharmacokinetics of tacrolimus.
METHODS
Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science (SCI), MEDLINE, and Embase were systematically searched from inception to August 2022. The outcomes were weight-adjusted daily dose and dose-adjusted trough concentration (C/Dose).
RESULTS
The study included 2931 renal transplant recipients from 18 publications. Weight-adjusted daily dose of CYP3A4*1/*1 carriers was 0.04 (WMD = 0.04, 95% CI: 0.02 to 0.06), 0.03 (WMD = 0.03, 95% CI: 0.02 to 0.05), 0.02 (WMD = 0.02, 95% CI: 0.01 to 0.03), or 0.02 mg/kg/day (WMD = 0.02, 95% CI: 0.00 to 0.04) higher than CYP3A4*22 carriers in Caucasians at 1 month, 3 months, 6 months, or 12 months post-transplantation. Conversely, C0/Dose was lower for CYP3A4*1/*1 carriers at 3 days (SMD = -0.35, 95% CI: -0.65 to -0.06), 1 month (SMD = -0.67, 95% CI: -1.16 to -0.18), 3 months (SMD = -0.60, 95% CI: -0.89 to -0.31), 6 months (SMD = -0.76, 95% CI: -1.49 to -0.04), or 12 months post-transplantation (SMD = -0.69, 95% CI: -1.37 to 0.00). Furthermore, C/Dose of POR*1/*1 carriers was 22.64 (WMD = 22.64, 95% CI: 2.54 to 42.74) or 19.41 (ng/ml)/(mg/kg/day) (WMD = 19.41, 95% CI: 9.58 to 29.24) higher than POR*28 carriers in CYP3A5 expressers at 3 days or 7 days post-transplantation, and higher in Asians at 6 months post-transplantation (SMD = 0.96, 95% CI: 0.50 to 1.43).
CONCLUSIONS
CYP3A4*22 variant in Caucasians restrains the metabolism of tacrolimus, while POR*28 variant in CYP3A5 expressers enhances the metabolism of tacrolimus for renal transplant recipients. However, further well-designed prospective studies are necessary to substantiate these conclusions given some limitations.

PROcedure-SPECific postoperative pain management guideline for laparoscopic colorectal surgery: A systematic review with recommendations for postoperative pain management.
Colorectal cancer is the second most common cancer diagnosed in women and third most common in men. Laparoscopic resection has become the standard surgical technique worldwide given its notable benefits, mainly the shorter length of stay and less postoperative pain. The aim of this systematic review was to evaluate the current literature on postoperative pain management following laparoscopic colorectal surgery and update previous procedure-specific pain management recommendations. The primary outcomes were postoperative pain scores and opioid requirements. We also considered study quality, clinical relevance of trial design, and a comprehensive risk-benefit assessment of the analgesic intervention. We performed a literature search to identify randomised controlled studies (RCTs) published before January 2022. Seventy-two studies were included in the present analysis. Through the established PROSPECT process, we recommend basic analgesia (paracetamol for rectal surgery, and paracetamol with either a nonsteroidal anti-inflammatory drug or cyclo-oxygenase-2-specific inhibitor for colonic surgery) and wound infiltration as first-line interventions. No consensus could be achieved either for the use of intrathecal morphine or intravenous lidocaine; no recommendation can be made for these interventions. However, intravenous lidocaine may be considered when basic analgesia cannot be provided.

Meta-Analysis Review
BACKGROUND
The ergogenic effects of caffeine intake on exercise performance are well-established, even if differences exist among individuals in response to caffeine intake. The genetic variation of a specific gene, human cytochrome P450 enzyme 1A2 (CYP1A2) (rs762551), may be one reason for this difference. This systematic review and meta-analysis aimed to comprehensively evaluate the influence of CYP1A2 gene types on athletes' exercise performance after caffeine intake.
METHODS
A literature search through 4 databases (Web of Science, PubMed, Scopus, and China National Knowledge Infrastructure) was conducted until March 2023. The effect size was expressed as the weighted mean difference (WMD) by calculating fixed effects meta-analysis if heterogeneity was not significant (I ≤ 50% and p ≥ 0.1). Subgroup analyses were performed based on AA and AC/CC genotype of CYP1A2.
RESULTS
The final number of studies meeting the inclusion criteria was 12 (n = 666 participants). The overall analysis showed that the cycling time trial significantly improved after caffeine intake (WMD = -0.48, 95% confidence interval (95%CI): -0.83 to -0.13, p = 0.007). In subgroup analyses, acute caffeine intake improved cycling time trial only in individuals with the A allele (WMD = -0.90, 95%CI: -1.48 to -0.33, p = 0.002), but not the C allele (WMD = -0.08, 95%CI: -0.32 to 0.17, p = 0.53). Caffeine supplementation did not influence the Wingate (WMD = 8.07, 95%CI: -22.04 to 38.18, p = 0.60) or countermovement jump test (CMJ) performance (WMD = 1.17, 95%CI: -0.02 to 2.36, p = 0.05), and these outcomes were not influenced by CYP1A2 genotype.
CONCLUSION
Participants with the CYP1A2 genotype with A allele improved their cycling time trials after caffeine supplementation. However, compared to placebo, acute caffeine supplementation failed to increase the Wingate or CMJ performance, regardless of CYP1A2 genotype.

Review
INTRODUCTION
Quetiapine exhibits notable pharmacokinetic and pharmacodynamic (PK/PD) variability, the origins of which are poorly understood. This systematic review summarizes published population PK/PD studies and identifies significant covariates accounting for this variability to inform precision dosing.
METHODS
We systematically searched the PubMed, Web of Science, and Embase databases and compared study characteristics, model parameters, and covariate effects. Visual predictive distributions were used to compare different models. Forest plots and Monte Carlo simulations were used to assess the influence of covariates.
RESULTS
Six population PK and three population PK/PD studies were included. The median apparent clearance in adults was 87.7 L/h. Strong and moderate cytochrome P450 3A4 inducers increased the apparent clearance approximately fourfold, while strong cytochrome P450 3A4 inhibitors reduced it by 93%. The half-maximum effect concentrations were 82.8 ng/mL for the Brief Psychiatric Rating Scale and 583 ng/mL for dopamine D receptor occupancy. Both treatment duration and quetiapine exposure were associated with weight gain.
CONCLUSIONS
Concurrent administration of potent or moderate CYP3A4 inducers and inhibitors need to be avoided in quetiapine-treated patients. When co-medication is required, it is recommended to adjust the dosage based on therapeutic drug monitoring. Additional research is warranted to delineate the dose-exposure-response relationships of quetiapine and active metabolite norquetiapine in pediatrics, geriatrics, hepatically-impaired patients, and women using contraceptives or are pregnant or menopausal.
