BACKGROUND
Conflicting evidence exists regarding the optimal waiting time for stable analgesic and vasoconstrictive effects after local infiltration of lidocaine with epinephrine. An objective review is needed to dispel surgical dogma.
METHODS
This systematic review (PROSPERO ID: CRD42022362414) included RCTs and prospective cohort studies. Primary outcomes were (1) onset of analgesia and (2) onset of stable hypoperfusion, assessed directly, or measured indirectly using perfusion imaging. Other data extracted include waiting strategies, means of outcome assessment, anaesthetic concentrations, volume/endpoint of infiltration, and injection sites. Methodological quality was evaluated using the Cochrane risk-of-bias tool for randomized trials. Articles describing waiting strategies were critically appraised by the Joanna Briggs Institute tools.
RESULTS
Twenty-four articles were analysed, comprising 1013 participants. Ten investigated analgesia onset. Their pooled mean was 2.1 min (range 0.4-9.0 min). This varied with anatomic site and targeted nerve diameter. Fourteen articles investigated onset of stable hypoperfusion. Four observed bleeding intraoperatively, finding the minimum time to hypoperfusion at 7.0 min in the eyelid skin and 25.0 min in the upper limb. The ten remaining studies used perfusion imaging, reporting a wide range of results (0.0-30.0 min) due to differences in anatomic sites and depth, resolution and artefacts. Studies using near-infrared reflectance spectroscopy and hyperspectral imaging correlated with clinical observations. Thirteen articles discussed waiting strategies, seven relating to large-volume tumescent local infiltration anaesthesia. Different waiting strategies exist for emergency, arthroscopic and cosmetic surgeries, according to the degree of hypoperfusion required. In tumescent liposuction, waiting 10.0-60.0 min is the norm.
CONCLUSION
Current literature suggests that around 2 min are required for most patients to achieve complete analgesia in all sites and with all anaesthesia concentrations. Waiting around 7 min in eyelids and at least 25 min in other regions results in optimal hypoperfusion. The strategies discussed inform decisions of when and how long to wait.

Meta-Analysis
OBJECTIVE
Hip fractures are the most common fractures among older adults, with most patients undergoing surgery. The debate regarding the type of anesthetic technique for hip fracture surgery is still ongoing. This meta-analysis aimed to compare the intraoperative and postoperative outcomes of spinal and general anesthesia in older patients undergoing hip fracture surgery.
METHODS
Eligible studies that compared the effects of spinal and general anesthesia were systematically searched from PubMed, Embase, and the Cochrane Library until May 27, 2022. The intraoperative and postoperative outcomes of the two anesthesia techniques were compared. Quality assessment, heterogeneity analysis, and publication bias of the studies were also assessed.
RESULTS
Nine articles of methodological quality were included in the meta-analysis. The pooled results revealed that there were significant differences in hypotension (risk ratio [RR] (95% confidence interval [CI]) = 0.81 (0.68, 0.97), p = 0.02) and ephedrine dose (weighted mean difference [WMD] [95%CI] = -20.94 [-37.50, -4.37] mg, p = 0.01) between the spinal and general anesthesia groups. However, no significant differences were observed in the use of ephedrine (RR [95% CI] = 0.77 [0.19, 3.05]), blood loss (WMD [95%CI] = -34.38 [-89.56, 20.80) mL], myocardial infarction (RR [95% CI] = 0.78 [0.31, 1.94] mL), heart failure (RR [95% CI] = 0.87 [0.17, 4.36] mL), stroke (RR [95%CI) = 0.65 [0.22, 1.95] mL), postoperative nausea and vomiting (RR [95% CI] = 0.88 [0.17, 4.35] mL), delirium (RR [95% CI] = 1.08 [0.89, 1.31] mL), and mortality (RR [95% CI] = 1.10 [0.72, 1.68] mL) (all p < 0.05). No publication bias was observed in any of the included studies.
CONCLUSION
Compared to general anesthesia, spinal anesthesia was associated with a lower risk of intraoperative hypotension and lower doses of ephedrine in older patients undergoing hip fracture surgery.

Review
BACKGROUND
Hepatorenal syndrome (HRS), a consequence of liver cirrhosis, is the development of renal failure, which carries a grave prognosis. Reversing acute renal failure with various vasoconstrictor therapies at an appropriate time favors a good prognosis, especially when a liver transplant is not feasible.
OBJECTIVE
This study aims to compare various treatment modalities to deduce an effective way to manage HRS.
METHODS
The authors conducted a literature search in PubMed, Google Scholar, the Cochrane Library, and Science Direct in October 2022, using regular and MeSH keywords. A total of 1072 articles were identified. The PRISMA guidelines were used, the PICO framework was addressed, and the inclusion criteria were set based on studies from the past 10 years. After quality assessment, 14 studies were included for in-depth analysis in this review. Results: A total of 14 studies were included after quality assessment, including randomized controlled trials, systematic reviews, meta-analyses, and observational cohort studies. Nine hundred and forty-one patients represented this review's experimental and observational studies, apart from the other systematic reviews analyzed. Nine studies discovered that Terlipressin, especially when administered with albumin, was more effective than other conventional treatment modalities, including norepinephrine and midodrine, in terms of improving mortality and reversing the HRS. Four studies suggested that terlipressin exhibited similar effectiveness but found no significant difference. In contrast, one study found that norepinephrine was superior to terlipressin when particularly considering the adverse effects.
CONCLUSION
Terlipressin, one of the most widely used vasoconstrictor agents across the world, seems to be effective in reversing renal failure in HRS. Although adverse effects are seen with this agent, it is still beneficial when compared to other medications. Further studies with larger sample sizes may be warranted.

Intravenous Tranexamic Acid Significantly Improved Visualization and Shortened the Operation Time in Arthroscopic Rotator Cuff Repair: A Systematic Review and Meta-analysis of Level I and II Studies.
PURPOSE
To further clarify the role of tranexamic acid (TXA) in arthroscopic rotator cuff repair (ARCR), especially visual field clarity and operation time.
METHODS
We searched the PubMed, Cochrane Library, and Embase databases to find prospective randomized controlled clinical trials (RCTs) examining the use of TXA in ARCR. All included RCTs were evaluated for methodological quality using the Cochrane Collaboration's risk of bias tool. We used Review Manager 5.3 for meta-analysis and calculated the weighted mean difference (WMD) and 95% confidence interval (CI) of the related outcome indicators. The GRADE system was used to evaluate the strength of the clinical evidence provided by the included studies.
RESULTS
Six RCTs (3 Level I, 3 Level II) from four countries or regions were included in this study: 2 studies used intra-articular (IA) TXA, and 4 studies used intravenous TXA. A total of 451 patients underwent ARCR, including 227 patients in the TXA group and 224 patients in the non-TXA group. In 2 RCTs evaluating good visualization, intravenous TXA achieved a better surgical field of view in ARCR compared to the control group (P =.036; P = .045). Meta-analysis showed that compared with non-TXA, intravenous TXA shortened the operation time (WMD = -12.87 min, 95% CI: -18.81 to -6.93). These two RCTs did not reveal a statistically significant difference in the impact of intravenous TXA and non-TXA on mean arterial pressure (MAP) (P = .306; P = .549). Compared with epinephrine (EPN), IA TXA had no significant effects on improving the visual field clarity under arthroscopy, shortening the operation time or reducing the total amount of irrigation fluid (P > .05). Compared with saline irrigation, IA TXA improved the surgical field of vision and shortened the operation time (P < .001). No adverse events were reported for either intravenous TXA or IA TXA.
CONCLUSIONS
Intravenous TXA can shorten the operation time of ARCR, and the conclusions of existing RCTs suggest that intravenous TXA can improve visual field clarity during ARCR, thus supporting the application of intravenous TXA in ARCR. Compared with EPN, IA TXA was not better at improving the visual field clarity under arthroscopy and shortening the operation time, but it was better than saline irrigation.

Meta-Analysis Review
Continuous positive airway pressure is the first-line and gold-standard treatment for obstructive sleep apnea (OSA). Pharmacotherapy is not commonly used in treating OSA until recently. Combined noradrenergic and antimuscarinic agents have been clinically applied for OSA patients with variable results. This meta-analysis study aimed to investigate the efficacy of the combined regimen on OSA. A systematic literature search was performed up to November 2022 for the effects of the combined regimen on OSA. Eight randomized controlled trials were identified and systematically reviewed for meta-analysis. There were significant mean differences between OSA patients taking a combined regimen and placebo in apnea-hypopnea index (AHI) [mean difference (MD) -9.03 events/h, 95%CI (-16.22, -1.83 events/h; P = 0.01] and lowest oxygen saturation [MD 5.61%, 95% CI % (3.43, 7.80); P < 0.01]. Meta-regression showed that a higher proportion of male participants was associated with a greater reduction of AHI (p = 0.04). This study showed a positive but modest effect of pharmacotherapy in the reduction of OSA severity. The combination drugs are most applicable to male OSA patients based on their efficacy and pharmacological susceptibility. Pharmacotherapy may be applied as an alternative, adjunctive or synergistic treatment under careful consideration of its side effects.

Meta-Analysis Review
BACKGROUND
Menstrual migraine is a subtype of migraine disease that is typically more disabling, longer-lasting, and more challenging to treat. The purpose of this network meta-analysis (NMA) is to compare the relative efficacy of treatments for menstrual migraine.
METHODS
We systematically searched databases, including PubMed, EMBASE, and Cochrane, and included all eligible randomized controlled trials in the study. We conducted the statistical analysis using Stata version 14.0, based on the frequentist framework. We used the Cochrane Risk of Bias tool for randomized trials version 2 (RoB2) to assess the risk of bias of the included studies.
RESULTS
This network meta-analysis included 14 randomized controlled trials with 4601 patients. For short-term prophylaxis, frovatriptan 2.5 mg twice daily had the highest probability of effectiveness [OR = 1.87 (95% CI: 1.48 to 2.38)] compared to placebo. For acute treatment, the results showed that sumatriptan 100 mg [OR = 4.32 (95% CI: 2.95 to 6.34)] was the most effective treatment compared to placebo.
CONCLUSIONS
These findings suggest that frovatriptan 2.5 mg twice daily was best for short-term prevention, sumatriptan 100 mg were best for acute treatment. More high-quality randomized trials are required to determine the most effective treatment.

Review
The functions of cocaine- and amphetamine-regulated transcript (CART) neuropeptide encoded by the gene vary from modifying behavior and pain sensitivity to being an antioxidant. Putative CART peptide receptor GPR160 was implicated recently in the pathogenesis of cancer. However, the exact role of CART protein in the development of neoplasms remains unclear. This systematic review includes articles retrieved from the Scopus, PubMed, Web of Science and Medline Complete databases. Nineteen publications that met the inclusion criteria and describe the association of CART and cancer were analyzed. CART is expressed in various types of cancer, e.g., in breast cancer and neuroendocrine tumors (NETs). The role of CART as a potential biomarker in breast cancer, stomach adenocarcinoma, glioma and some types of NETs was suggested. In various cancer cell lines, acts an oncogene, enhancing cellular survival by the activation of the ERK pathway, the stimulation of other pro-survival molecules, the inhibition of apoptosis or the increase in cyclin D1 levels. In breast cancer, CART was reported to protect tumor cells from tamoxifen-mediated death. Taken together, these data support the role of CART activity in the pathogenesis of cancer, thus opening new diagnostic and therapeutic approaches in neoplastic disorders.

Meta-Analysis Review
INTRODUCTION
Studies from more than 10 years ago showed epinephrine treatment of food-induced anaphylaxis in the emergency department (ED) was unacceptably low. We investigated whether epinephrine treatment of food-induced and other cause anaphylaxis in United States and Canadian EDs has changed over time.
METHODS
Guided by a health sciences librarian, we performed a systematic search in Medline, Embase, and Web of Science on 11 January 2023. We included observational studies that reported epinephrine use to treat anaphylaxis in the ED. We stratified by anaphylaxis etiology (food-, venom-, medication-induced, or any cause). Associations between year and epinephrine use were tested using Spearman correlation and proportional meta-analysis.
RESULTS
Of 2458 records identified in our initial search, 40 met inclusion criteria. Of these, 14 examined food-induced, 4 venom-induced, 0 medication-induced, and 24 any cause anaphylaxis. For epinephrine treatment of food-induced anaphylaxis in the ED, among studies using similar definition of anaphylaxis, meta-analysis showed a pooled value of 20.7% (95% CI 17.8, 23.8) for studies performed >10 years ago and 45.1% (95% CI 38.4, 52.0) from those in the last 10 years. For anaphylaxis of any cause, there was no change over time, with a pooled value of 45.0% (95% CI 39.8, 50.3) over the last 10 years.
DISCUSSION
Epinephrine treatment of food-induced anaphylaxis in the ED has increased over time. There was no clear change for anaphylaxis of any cause. Over the last 10 years, approximately 45% of ED patients with anaphylaxis received epinephrine. A limitation of the evidence is heterogeneity in anaphylaxis definitions.

BMC Neurology Jun 2023Many drugs are prescribed in relieving acute migraine attacks, we aim to compare metoclopramide with other antimigraine drugs. (Meta-Analysis)
Meta-Analysis
The efficacy and safety of metoclopramide in relieving acute migraine attacks compared with other anti-migraine drugs: a systematic review and network meta-analysis of randomized controlled trials.
BACKGROUND
Many drugs are prescribed in relieving acute migraine attacks, we aim to compare metoclopramide with other antimigraine drugs.
METHODS
We searched online databases like PubMed, Cochrane Library, Scopus, and Web of Science till June 2022 for RCTs that compared metoclopramide alone with placebo or active drugs. The main outcomes were the mean change in headache score and complete headache relief. The secondary outcomes were the rescue medications need, side effects, nausea and recurrence rate. We qualitatively reviewed the outcomes. Then, we performed the network meta-analyses (NMAs) when it was possible. which were done by the Frequentist method using the MetaInsight online software.
RESULTS
Sixteen studies were included with a total of 1934 patients: 826 received metoclopramide, 302 received placebo, and 806 received other active drugs. Metoclopramide was effective in reducing headache outcomes even for 24 h. The intravenous route was the most chosen route in the included studies and showed significant positive results regarding headache outcomes; however, the best route whether intramuscular, intravenous, or suppository was not compared in the previous studies. Also, both 10 and 20 mg doses of metoclopramide were effective in improving headache outcomes; however, there was no direct comparison between both doses and the 10 mg dose was the most frequently used dosage. In NMA of headache change after 30 min or 1 h, metoclopramide effect came after granisetron, ketorolac, chlorpromazine, and Dexketoprofen trometamol. Only granisetron's effect was significantly higher than metoclopramide's effect which was only significantly higher than placebo and sumatriptan. In headache-free symptoms, only prochlorperazine was non-significantly higher than metoclopramide which was higher than other medications and showed significantly higher effects only with placebo. In rescue medication, metoclopramide's effect was only non-significantly lower than prochlorperazine and chlorpromazine while its effect was higher than other drugs and showed higher significant effects only than placebo and valproate. In the recurrence rate, studies showed no significant difference between metoclopramide and other drugs. Metoclopramide significantly decreased nausea more than the placebo. Regarding side effects, metoclopramide showed a lower incidence of mild side effects than pethidine and chlorpromazine and showed a higher incidence of mild side effects than placebo, dexamethasone, and ketorolac. The reported extrapyramidal symptoms with metoclopramide were dystonia or akathisia.
CONCLUSION
A dose of 10 mg IV Metoclopramide was effective in relieving migraine attacks with minimal side effects. Compared to other active drugs, it only showed a lower significant effect compared with granisetron regarding headache change while it showed significantly higher effects only with placebo in both rescue medication needs and headache-free symptoms and valproate in only rescue medication need. Also, it significantly decreased headache scores more than placebo and sumatriptan. However, more studies are needed to support our results.

BACKGROUND
Serotonin receptors 5-HT1B and 5-HT1D in the cerebral arteries are activated by the 5-hydroxytryptophan agonists (triptans) to relieve the discomfort associated with migraines. Even though triptans are often used to treat acute migraines, there is some debate over their effectiveness.
OBJECTIVE
Our systematic review aimed to evaluate the effectiveness of triptans for acute treatment of migraine in young individuals.
METHODS
Utilizing the databases of Google Scholar, Cochrane Library, and PubMed, a literature search was conducted, and all papers published till July 2022 were included. This systematic review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. In addition to the Boolean operators AND, OR, and NOT, the following descriptive terms were also used: "Triptans," "Pediatric Migraine," "Migraine disorders," "Headache," "Children," and "Adolescent."
RESULTS
A total of 1047 studies were identified, and 25 articles were finally included in the study. 17 of them were RCTs while the remaining were non-randomized trials. Most studies recruited participants aged between 12-17 years. Among 25 studies, 7 reported sumatriptan use, 3 assessed a combination of sumatriptan and naproxen, 4 were on almotriptan, 1 on eletriptan, 6 on rizatriptan, and 4 on zolmitriptan use.
CONCLUSION
We found that rizatriptan (good tolerability profile with a dose of 5 mg) and sumatriptan (nasal spray, 10 mg and 20 mg) had higher efficiency as compared to other triptans. Regardless of type or dose, all triptans are generally well tolerated by patients, but a few adverse effects such as light-headedness (sumatriptan), nasopharyngitis, and, muscular spasms (sumatriptan/ naproxen), somnolence, and dry mouth (rizatriptan), and dizziness (zolmitriptan group) were reported with the triptans.
