Comparative Study Meta-Analysis Review
A total knee arthroplasty (TKA) has always been associated with moderate-to-severe pain. A systematic review of randomized controlled trials (RCTs) and non-RCTs was performed to evaluate the efficacy and safety of pain control of adductor canal block (ACB) and femoral nerve block (FNB) after TKA.Relevant literatures about the ACB and FNB after TKA for reducing pain were searched from Medline (1996-January, 2015), Embase (1980-January, 2015), PubMed (1980-January, 2015), Web of Science (1980-January, 2015), and The Cochrane Central Register of Controlled Trials. High-quality RCTs and non-RCTs were picked to evaluate the visual analogue scale (VAS) and other outcome. This systematic review and meta-analysis were performed according to the PRISMA statement criteria. The software RevMan 5.30 was used for the meta-analysis.Eight literatures fitted into the inclusion criteria. There were no significant differences in VAS score with rest or mobilization at 4, 24, and 48 h between ACB group and FNB group. There were also no significant differences in the strength of quadriceps and adductor, the length of hospital stay, and complications of vomiting and nausea.Present meta-analysis indicated that ACB shows no superiority than FNB group. Both of them can reduce the pain score after TKA. As referred to which method to adopt, it is determined by the preference of the surgeons and anesthesiologists.

Meta-Analysis
AIMS
As an emerging interventional technique to treat resistant hypertension, renal denervation (RDN) has also attracted considerable attention due to its potential beneficial effects on glucose and lipid metabolism. Given that inconsistent results were documented among studies, we aimed to perform a systematic review and meta-analysis to elaborate on this issue.
METHODS
The PubMed, EMBASE, Web of Science (SCI) and ClinicalTrials.gov databases were comprehensively searched from their inception date to June 18, 2020, for relevant clinical studies evaluating the efficacy of RDN on glucose and lipid levels. The outcomes of interest were changes in fasting glucose, insulin, C-peptide, hemoglobin A1C (HbA1C), homeostatic model assessment-insulin resistance (HOMA-IR), cholesterol and triglyceride (TG) levels before versus after RDN and also RDN versus the control group. The mean differences (MDs) of the outcomes measured before versus after RDN and RDN versus the control group were pooled by a randomized effects model. Heterogeneity was quantified with Chi-square (χ) and inconsistency index (I). Assessment of publication bias was performed by the funnel plot and Egger's test.
RESULTS
A total of 1600 studies were initially identified. Nineteen of the identified studies (six randomized controlled studies, one non-randomized controlled studies and 12 observational cohort studies) involving 2245 subjects were included in the final analysis. No significant change was observed after RDN in fasting glucose (weighted mean difference [WMD] - 0.19 mmol/L; 95% CI - 0.37, 0.00 mmol/L), insulin (standardized mean difference [SMD] - 0.01; 95% CI - 0.41, 0.39), C-peptide (SMD - 0.05; 95% CI - 0.30, 0.21), HbA1C (SMD - 0.05; 95% CI - 0.17, 0.07), HOMA-IR (SMD - 0.29; 95% CI - 0.72, 0.14), total cholesterol (TC) (WMD - 0.11 mmol/L; 95% CI - 0.37, 0.15 mmol/L), and low-density lipoprotein cholesterol (LDL-C) levels (WMD - 0.18 mmol/L; 95% CI - 0.59, 0.24 mmol/L) during follow-up. Changes in fasting glucose, insulin, HbA1C and TC levels in RDN groups were not significantly different from those in the control group. High-density lipoprotein cholesterol (HDL-C) and TG were slightly improved after RDN (WMD 0.07 mmol/L, 95% CI 0.01, 0.14 mmol/L; WMD - 0.26 mmol/l, 95% CI - 0.51, - 0.01 mmol/L, respectively). The funnel plot and Egger's test demonstrated the absence of potential publication bias.
CONCLUSIONS
Catheter-based RDN appeared to have no impact on glucose metabolism. There was a statistically significant but clinically negligible improvement in HDL-C and TG levels based on the current evidence. Future research with more rigorous designs is warranted to draw definitive conclusions.

Meta-Analysis Review
We systematically reviewed the safety and efficacy of perineural dexamethasone as an adjunct for peripheral nerve blockade in 29 controlled trials of 1695 participants. We grouped trials by the duration of local anaesthetic action (short- or medium- vs long-term). Dexamethasone increased the mean (95% CI) duration of analgesia by 233 (172-295) min when injected with short- or medium-term action local anaesthetics and by 488 (419-557) min when injected with long-term action local anaesthetics, p < 0.00001 for both. However, these results should be interpreted with caution due to the extreme heterogeneity of results, with I2 exceeding 90% for both analyses. Meta-regression did not show an interaction between dose of perineural dexamethasone (4-10 mg) and duration of analgesia (r2 = 0.02, p = 0.54). There were no differences between 4 and 8 mg dexamethasone on subgroup analysis.

Meta-Analysis
PURPOSE
Laparoscopic bariatric surgeries can cause intense postoperative pain. Opioid medication can alleviate the pain but can have harmful side effects especially in patients with obstructive sleep apnea. To promote early recovery, enhanced recovery after surgery guideline advises minimizing opioid use and opting for alternative analgesics. This paper aims to investigate the effect of regional anesthesia techniques through a systematic review and network meta-analysis. Primary outcome is postoperative morphine equivalent consumption at 24 h.
METHODS
Search was conducted in the following databases: PubMed, CENTRAL, Scopus, and EMBASE, from the inception until 10 January 2023. The eligibility criteria were determined by PICOS, including postoperative opioid consumption, pain scores, time to ambulate, use of additional analgesics, and adverse events. The quality assessment was performed using the Risk of Bias 2 Tool, and the certainty of evidence was assessed using the GRADE approach. Funnel plots were used to evaluate publication bias.
RESULTS
We included 22 studies in quantitative synthesis. A review of 12 studies found that all techniques had a lower mean consumption of opioids compared to placebo or no intervention, with TAP block having the greatest reduction. The quality of evidence for postoperative pain, PONV, time to deambulate, and use of rescue analgesics, was rated as moderate, with TAP block being the most effective intervention. There was no publication bias in any outcome.
CONCLUSIONS
TAP block is superior to other regional anesthesia techniques in reducing opioid consumption, pain, PONV, and use of rescue analgesics in bariatric surgery. However, further research is needed.

Meta-Analysis Review
Ultrasound-guided erector spinae plane block (ESPB) has been used in many studies for providing opioid-sparing analgesia after various cardiac surgeries. We performed a systematic review and meta-analysis of randomized controlled trials to assess the efficacy of ESPB in cardiac surgeries. We searched PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar to identify the studies in which ESPB was compared with the control group/sham block in patients undergoing cardiac surgeries. The primary outcomes were postoperative opioid consumption and postoperative pain scores. The secondary outcomes were intraoperative opioid consumption, ventilation time, time to the first mobilization, length of ICU and hospital stay, and adverse events. Out of 607 studies identified, 16 studies (n = 1110 patients) fulfilled inclusion criteria and were used for qualitative and quantitative analysis. Although, 24-hr opioid consumption were comparable in both groups group (MD, -18.74; 95% CI, -46.85 to 9.36, P = 0.16), the 48-hr opioid consumption was significantly less in ESPB group than control ((MD, -11.01; 95% CI, -19.98 to --2.04, P = 0.02). The pain scores at various time intervals and intraoperative opioid consumption were significantly less in ESPB group. Moreover, duration of ventilation, time to the first mobilization, and length of ICU and hospital were also less in ESPB group (P < 0.00001, P < 0.00001, P < 0.00001, and P < 0.0001, respectively). This systematic review and meta-analysis demonstrated that ESPB provides opioid-sparing perioperative analgesia, facilitates early extubation and mobilization, leads to early discharge from ICU and hospital, and has lesser pruritus when compared to control in patients undergoing cardiac surgeries.

Meta-Analysis Review
The present study aims to evaluate the clinical outcomes following renal denervation (RDN) for hypertensive patients with chronic kidney disease (CKD). Prospective studies published between January 1, 2010 and November 15, 2022 where systematically identified for RDN outcomes on office and ambulatory blood pressure, estimated glomerular filtration rate (eGFR), creatinine and procedural characteristics from three online databases (Medline, PubMed, EMBASE). Random effects model to combine risk ratios and mean differences was used. Where possible, clinical outcomes were pooled and analyzed at 6, 12 and 24 months. Significance was set at p ≤ 0.05. 11 prospective trials, with a total of 226 patients with treatment resistant HTN receiving RDN met the inclusion criteria. Age ranged from 42.5 ± 13.8 to 66 ± 9. Main findings of this review included a reduction in systolic and diastolic office blood pressure at 6 [-19.8 (p < 0.00001)/-15.2 mm Hg (p < 0.00001)] and 12 months [-21.2 (p < 0.00001)/-9.86 mm Hg (p < 0.0005)] follow-up compared to baseline. This was also seen in systolic and diastolic 24-hour ambulatory blood pressure at 6 [-9.77 (p = 0.05)/-3.64 mm Hg (p = 0.09)] and 12 months [-13.42 (p = 0.0007)/-6.30 mm Hg (p = 0.001)] follow-up compared to baseline. The reduction in systolic and diastolic 24-hour ambulatory blood pressure was maintained to 24 months [(-16.30 (p = 0.0002)/-6.84 mm Hg (p = 0.0010)]. Analysis of kidney function through eGFR demonstrated non-significant results at 6 (+1.60 mL/min/1.73 m, p = 0.55), 12 (+5.27 mL/min/1.73 m, p = 0.17), and 24 months (+7.19 mL/min/1.73 m, p = 0.36) suggesting an interruption in natural CKD progression. Similar results were seen in analysis of serum creatinine at 6 (+0.120 mg/dL, p = 0.41), 12 (+0.100 mg/dL, p = 0.70), and 24 months (+0.07 mg/dL, p = 0.88). Assessment of procedural complications deemed RDN in a CKD cohort to be safe with an overall complication rate of 4.86%. With the current advances in RDN and its utility in multiple chronic diseases beyond hypertension, the current study summarizes critical findings that further substantiate the literature regarding the potential of such an intervention to be incorporated as an effective treatment for resistant hypertension and CKD.

Meta-Analysis Review
BACKGROUND
This meta-analysis aimed to evaluate the body of evidence investigating the post-operative use of non-opioid analgesic drugs and techniques in endocrine neck surgeries. Adequate pain control is crucial for successful recovery after thyroid and parathyroid surgery. Effective postoperative pain control can shorten hospital stay, improve postoperative outcomes, decrease morbidity and improve the overall patient experience. Traditionally, opioids have been the mainstay of postoperative analgesia after thyroid and parathyroid surgeries. However, the use of opioids has been linked to an increased incidence of postoperative complications.
METHODS
A comprehensive systematic literature review via Medline, Embase, Web of Science and Cochrane Central Register for Controlled Trials from inception until December 26th, 2020 was conducted, followed by meta-analysis. Abstract and full-text screening, data extraction and quality assessment were independently conducted by 2 investigators. Odds ratios (OR), mean differences (MD) and 95% confidence intervals were calculated using RevMan 5.3.
RESULTS
Sixty-five randomized control trials were identified from 486 unique publications. Pooled MD and 95% confidence interval for pain scores were higher for the control group at 24 h postoperatively both at rest (-0.65 [-0.92, -0.37]) and with swallowing (-0.77 [-1.37, -0.16]). These differences were statistically significant. The pooled MD and confidence interval for postoperative analgesic requirements was lower in the intervention group (-1.38 [-1.86, -0.90]). The incidence of PONV had a pooled OR of 0.67 [0.48, 0.94].
CONCLUSION
Non-opioid analgesia was superior to the control group for pain control in patients undergoing thyroid and parathyroid operations with no significant difference in complications.

Review
OBJECTIVE:
The aim was to evaluate the effectiveness of the experimental synergists muscle ablation model to promote muscle hypertrophy, determine the period of greatest hypertrophy and its influence on muscle fiber types and determine differences in bilateral and unilateral removal to reduce the number of animals used in this model.
METHOD:
Following the application of the eligibility criteria for the mechanical overload of the plantar muscle in rats, nineteen papers were included in the review.
RESULTS:
The results reveal a greatest hypertrophy occurring between days 12 and 15, and based on the findings, synergist muscle ablation is an efficient model for achieving rapid hypertrophy and the contralateral limb can be used as there was no difference between unilateral and bilateral surgery, which reduces the number of animals used in this model.
CONCLUSION:
This model differs from other overload models (exercise and training) regarding the characteristics involved in the hypertrophy process (acute) and result in a chronic muscle adaptation with selective regulation and modification of fast-twitch fibers in skeletal muscle. This is an efficient and rapid model for compensatory hypertrophy.

Comparative Study Meta-Analysis
BACKGROUND
Cervical dystonia is a disabling medical condition that drastically decreases quality of life. Surgical treatment consists of peripheral nerve denervation procedures with or without myectomies or deep brain stimulation (DBS). The current objective was to compare the efficacy of peripheral denervation versus DBS in improving the severity of cervical dystonia through a systematic review and meta-analysis.
METHODS
A search of PubMed, MEDLINE, EMBASE, and Web of Science electronic databases was conducted in accordance with PRISMA guidelines. Preoperative and postoperative Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total scores were used to generate standardized mean differences and 95% confidence intervals (CIs), which were combined in a random-effects model. Both mean percentage and absolute reduction in TWSTRS scores were calculated. Absolute reduction was used for forest plots.
RESULTS
Eighteen studies met the inclusion criteria, comprising 870 patients with 180 (21%) undergoing DBS and 690 (79%) undergoing peripheral denervation procedures. The mean follow-up time was 31.5 months (range, 12-38 months). In assessing the efficacy of each intervention, forest plots revealed significant absolute reduction in total postoperative TWSTRS scores for both peripheral denervation (standardized mean difference 1.54; 95% CI 1.42-1.66) and DBS (standardized mean difference 2.07; 95% CI 1.43-2.71). On subgroup analysis, DBS therapy was significantly associated with improvement in postoperative TWSTRS severity (standardized mean difference 2.08; 95% CI 1.66-2.50) and disability (standardized mean difference 2.12; 95% CI 1.57-2.68) but not pain (standardized mean difference 1.18; 95% CI 0.80-1.55).
CONCLUSIONS
Both peripheral denervation and DBS are associated with a significant reduction in absolute TWSTRS total score, with no significant difference in the magnitude of reduction observed between the 2 treatments. Further comparative data are needed to better evaluate the long-term results of both interventions.

Meta-Analysis Review
BACKGROUND
Radiofrequency (RF) denervation, an invasive treatment for chronic low back pain (CLBP), is used most often for pain suspected to arise from facet joints, sacroiliac (SI) joints or discs. Many (uncontrolled) studies have shown substantial variation in its use between countries and continued uncertainty regarding its effectiveness.
OBJECTIVES
The objective of this review is to assess the effectiveness of RF denervation procedures for the treatment of patients with CLBP. The current review is an update of the review conducted in 2003.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, three other databases, two clinical trials registries and the reference lists of included studies from inception to May 2014 for randomised controlled trials (RCTs) fulfilling the inclusion criteria. We updated this search in June 2015, but we have not yet incorporated these results.
SELECTION CRITERIA
We included RCTs of RF denervation for patients with CLBP who had a positive response to a diagnostic block or discography. We applied no language or date restrictions.
DATA COLLECTION AND ANALYSIS
Pairs of review authors independently selected RCTs, extracted data and assessed risk of bias (RoB) and clinical relevance using standardised forms. We performed meta-analyses with clinically homogeneous studies and assessed the quality of evidence for each outcome using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach.
MAIN RESULTS
In total, we included 23 RCTs (N = 1309), 13 of which (56%) had low RoB. We included both men and women with a mean age of 50.6 years. We assessed the overall quality of the evidence as very low to moderate. Twelve studies examined suspected facet joint pain, five studies disc pain, two studies SI joint pain, two studies radicular CLBP, one study suspected radiating low back pain and one study CLBP with or without suspected radiation. Overall, moderate evidence suggests that facet joint RF denervation has a greater effect on pain compared with placebo over the short term (mean difference (MD) -1.47, 95% confidence interval (CI) -2.28 to -0.67). Low-quality evidence indicates that facet joint RF denervation is more effective than placebo for function over the short term (MD -5.53, 95% CI -8.66 to -2.40) and over the long term (MD -3.70, 95% CI -6.94 to -0.47). Evidence of very low to low quality shows that facet joint RF denervation is more effective for pain than steroid injections over the short (MD -2.23, 95% CI -2.38 to -2.08), intermediate (MD -2.13, 95% CI -3.45 to -0.81), and long term (MD -2.65, 95% CI -3.43 to -1.88). RF denervation used for disc pain produces conflicting results, with no effects for RF denervation compared with placebo over the short and intermediate term, and small effects for RF denervation over the long term for pain relief (MD -1.63, 95% CI -2.58 to -0.68) and improved function (MD -6.75, 95% CI -13.42 to -0.09). Lack of evidence of short-term effectiveness undermines the clinical plausibility of intermediate-term or long-term effectiveness. When RF denervation is used for SI joint pain, low-quality evidence reveals no differences from placebo in effects on pain (MD -2.12, 95% CI -5.45 to 1.21) and function (MD -14.06, 95% CI -30.42 to 2.30) over the short term, and one study shows a small effect on both pain and function over the intermediate term. RF denervation is an invasive procedure that can cause a variety of complications. The quality and size of original studies were inadequate to permit assessment of how often complications occur.
AUTHORS' CONCLUSIONS
The review authors found no high-quality evidence suggesting that RF denervation provides pain relief for patients with CLBP. Similarly, we identified no convincing evidence to show that this treatment improves function. Overall, the current evidence for RF denervation for CLBP is very low to moderate in quality; high-quality evidence is lacking. High-quality RCTs with larger patient samples are needed, as are data on long-term effects.
