Meta-Analysis
OBJECTIVES
The purpose of this study was to investigate the analgesic effects of duloxetine, specifically on postoperative pain, opioid consumption, and related side effects following total hip or knee arthroplasty.
METHODS
In this systematic review and meta-analysis, Medline, Cochrane, EMBASE, Scopus, and Web of Science were searched until November 2022 for studies which compared duloxetine with placebo when added to routine pain management protocols. Individual study risk of bias assessment was conducted based on Cochrane risk of bias tool 2. Random effect model meta-analysis was done on mean differences, to evaluate the outcomes.
RESULTS
Nine randomized clinical trials (RCT) were included in the final analysis, totaling 806 patients. Duloxetine reduced opioid consumption (oral morphine milligram equivalents) on postoperative days (POD) 2 (mean difference (MD): -14.35, P = .02), POD 3 (MD: -13.6, P < .001), POD 7 (MD: -7.81, P < .001), and POD 14 (MD: -12.72, P < .001). Duloxetine decreased pain with activity on POD 1, 3, 7, 14, 90 (All P < .05), and pain at rest on POD 2, 3, 7, 14, and 90 (all P < .05). There was no significant difference in the prevalence of the side effects, except for increased risk of somnolence/drowsiness (risk ratio: 1.87, P = .007).
CONCLUSION
Current evidence shows low to moderate opioid sparing effects of perioperative duloxetine and a statistically but not clinically significant reduction in pain scores. Patients treated with duloxetine had an increased risk for somnolence and drowsiness.

Meta-Analysis Review
AIM
Reducing postoperative opioid consumption is a key aim of enhanced recovery after colorectal surgery protocols. Potential solutions include anaesthetic techniques such as local infiltration of anaesthetic agents or transversus abdominis plane (TAP) blocks. This study aimed to assess the efficacy of liposomal bupivacaine (LB) for colorectal resections, across a variety of anaesthetic techniques.
METHODS
PubMed, Scopus and Embase databases were searched for relevant studies assessing LB, administered by any anaesthetic technique. The primary outcome was postoperative morphine consumed (milligrams) and the secondary outcome was length of stay (days). A Bayesian network meta-analysis comparing LB versus non-LB analgesia was performed alongside meta-regression for different surgical approaches.
RESULTS
Twelve trials were included, with a total of 2512 patients. LB-based wound infiltration was most likely to reduce length of stay followed by TAP block with LB (sum under the cumulative ranking [SUCRA] 85.55 and 70.26, respectively). TAP block with LB was most likely to reduce morphine requirements, followed by wound infiltration with LB (SUCRA 83.94 and 75.73, respectively). Compared to standard analgesia, LB-based wound infiltration reduced morphine usage (mean difference 36.64 mg, 95% credibility interval 15.64-59.20) and length of stay (mean difference 1.79 days, 95% credibility interval 0.59-3.81). On meta-regression, the findings held for minimally invasive surgery only.
CONCLUSION
Although LB-based interventions were associated with reduced postoperative morphine requirements and length of stay in this network meta-analysis, the confidence in these estimates was graded as very low. Further well-executed trials are required before LB can be recommended as a first-line agent.

Meta-Analysis
We aimed to make a general comparison between the safety and feasibility of a novel robotic platform, da Vinci single-port (SP) system with conventional robotic multiport (MP) and laparoendoscopic single-site systems (da Vinci Xi or Si) in three upper urinary tract procedures including robot-assisted partial nephrectomy (RAPN), robot-assisted pyeloplasty (RAP), and robot-assisted adrenalectomy (RA). After systematical searching of the literature up to October 2022 in PubMed, Web of Science™, and the Cochrane Library and Scopus databases, we extracted and processed the data in eligible literature for operative time, warm ischemia time (WIT), morphine milligram equivalent (MME), postoperative complications, and positive surgical margins (PSMs). A total of 752 patients who underwent robotic surgery for SP or MP from 11 articles were included in this meta-analysis. There was no statistically significant difference in operative time for either RAPN (standardized mean difference [SMD] -0.14, 95% confidence interval [CI] -0.30 to 0.03) or RA (SMD -0.51, 95% CI -1.08 to 0.06). However, for RAP, SP can save operation time (SMD -0.73, 95% CI -1.24 to -0.22). The introduction of SP did not increase complications to any degree, including total complication (risk ratio [RR] 0.89, 95% CI 0.52-1.53), minor complication (RR 0.43, 95% CI 0.13-1.36), and major complication (RR 0.85, 95% CI 0.34-2.09), nor the incidence of PSMs (RR 1.04, 95% CI 0.54-1.99). It is worth noting that although the SP system increased WIT (SMD 0.44, 95% CI 0.26-0.62), it had the benefit of reducing intraoperative pain for RAPN with regard of MME (SMD -0.40, 95% CI -0.71 to -0.09). In terms of postoperative pain, SP robotic surgery is beneficial for RAPN but will make WIT prolonged. RAP is probably the most suitable upper urinary tract procedure for which SP is an option, which helps to shorten the surgery time and achieve a minimally invasive wound at the same time. Our study has been registered in PROSPERO (Registration No.: CRD42022350317).

Orthopaedic Journal of Sports Medicine Jul 2022Postoperative treatment plans after orthopaedic procedures frequently include opioids for pain relief. (Review)
Review
BACKGROUND
Postoperative treatment plans after orthopaedic procedures frequently include opioids for pain relief.
PURPOSE
To evaluate opioid use in the early postoperative phase after arthroscopic rotator cuff repair (ARCR) to develop a procedure-specific understanding of the current role of opioids in pain management for this procedure.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
A PubMed search was used to identify eligible studies. Data on patient demographics, visual analog scale pain scores, and opioid use patterns (in morphine milligram equivalents [MMEs]) were collected and assessed. Cumulative MMEs were reported on postoperative day (POD) zero, and mean MMEs were reported on subsequent PODs (days 1, 2, 3, 5, 7, and 14). Metaregression, indices, and Cochran tests were used to evaluate study variation, heterogeneity, and variance.
RESULTS
A total of 1487 patients in 22 studies were included in the analysis. An estimated 51% (95% CI, 31%-70%) of patients with nerve blocks (NBs) were opioid-free through POD-0 versus 40% (95% CI, 1.2%-97%) of patients without NBs, which increased to 65% (95% CI, 55%-74%) versus 25% (95% CI, 1.7%-86%) by POD-1. Opioid requirements were highest in the first 72 hours after ARCR. NB use reduced opioid requirement on POD-0 compared with no NB use (15.8 vs 45.0 MMEs, respectively; < .001) but did not reduce requirements after that. In addition, NB use led to a statistically significant increase in opioid requirements on POD-7 (28.6 vs 9.5 MMEs, respectively; < .001). Using a model that assumes stable opioid requirements between our time points, weighted mean cumulative opioid consumption was 163 MMEs in the first week and 273 MMEs in the first 2 weeks (150 and 287 MMEs in patients with NB; 180 and 261 MMEs in patients without NB, respectively).
CONCLUSION
Opioid use is relatively common in the early postoperative period after ARCR. Pain scores and opioid requirements may spike on POD-1; however, patients should be educated and reassured that they will gradually decrease usage over the initial 2-week postoperative period.

Review
PURPOSE
Prior research has yielded mixed results regarding the impact of acarbose intake on glycemic markers. To provide a more comprehensive analysis, a systematic review and meta-analysis was performed to compile data from various randomized controlled trials (RCTs) examining the effects of acarbose intake on fasting blood sugar (FBS), insulin, hemoglobin A1C (HbA1c), and homeostasis model assessment of insulin resistance (HOMA-IR) in adults.
METHODS
To identify relevant literature up to April 2023, a comprehensive search was conducted on various scholarly databases, including PubMed, Web of Science, and Scopus databases. The effect size of the studies was evaluated using a random-effects model to calculate the weighted mean differences (WMD) and 95% confidence intervals (CI). Heterogeneity between studies was assessed using Cochran's Q test and I.
RESULTS
This systematic review and meta-analysis included a total of 101 RCTs with a total of 107 effect sizes. The effect sizes for FBS in milligrams per deciliter (mg/dl), insulin in picomoles per liter (pmol/l), hemoglobin A1C (HbA1c) in percentage (%), and homeostasis model assessment of insulin resistance (HOMA-IR) were 92, 46, 80, and 22, respectively. The pooled analysis indicated that acarbose intake resulted in significant decreases in FBS ( = 0.018), insulin ( < 0.001), HbA1c ( < 0.001), and HOMA-IR ( < 0.001).
CONCLUSION
The findings of this systematic review and meta-analysis suggest that acarbose intake can potentially lead to significant improvements in glycemic parameters by decreasing the levels of FBS, HbA1c, and insulin. However, larger and more rigorously designed studies are still needed to further evaluate and strengthen this association.

The management of chronic noncancer pain (CNCP) with chronic opioid therapy (COT) is controversial. There is a lack of consensus on how COT is defined resulting in unclear clinical guidance. This scoping review identifies and evaluates evolving COT definitions throughout the published clinical and scientific literature. Databases searched included PubMed, Embase, and Web of Science. A total of 227 studies were identified from 8,866 studies published between January 2000 and July 2019. COT definitions were classified by pain population of application and specific dosage/duration definition parameters, with results reported according to PRISMA-ScR. Approximately half of studies defined COT as "days' supply duration >90 days" and 9.3% defined as ">120 days' supply," with other days' supply cut-off points (>30, >60, or >70) each appearing in <5% of total studies. COT was defined by number of prescriptions in 63 studies, with 16.3% and 11.0% using number of initiations or refills, respectively. Few studies explicitly distinguished acute treatment and COT. Episode duration/dosage criteria was used in 90 studies, with 7.5% by Morphine Milligram Equivalents + days' supply and 32.2% by other "episode" combination definitions. COT definitions were applied in musculoskeletal CNCP (60.8%) most often, and typically in adults aged 18 to 64 (69.6%). The usage of ">90 days' supply" COT definitions increased from 3.2 publications/year before 2016 to 20.7 publications/year after 2016. An increasing proportion of studies define COT as ">90 days' supply." The most recent literature trends toward shorter duration criteria, suggesting that contemporary COT definitions are increasingly conservative. PERSPECTIVE: This study summarized the most common, current definition criteria for chronic opioid therapy (COT) and recommends adoption of consistent definition criteria to be utilized in practice and research. The most recent literature trends toward shorter duration criteria overall, suggesting that COT definition criteria are increasingly stringent.

Sports Health 2020The prescription of opioids after elective surgical procedures has been a contributing factor to the current opioid epidemic in North America.
CONTEXT
The prescription of opioids after elective surgical procedures has been a contributing factor to the current opioid epidemic in North America.
OBJECTIVE
To examine the opioid prescribing practices and rates of opioid consumption among patients undergoing common sports medicine procedures.
DATA SOURCES
A systematic review of the electronic databases EMBASE, MEDLINE, and PubMed was performed from database inception to December 2018.
STUDY SELECTION
Two investigators independently identified all studies reporting on postoperative opioid prescribing practices and consumption after arthroscopic shoulder, knee, or hip surgery. A total of 119 studies were reviewed, with 8 meeting eligibility criteria.
STUDY DESIGN
Systematic review.
LEVEL OF EVIDENCE
Level 4.
DATA EXTRACTION
The quantity of opioids prescribed and used were converted to milligram morphine equivalents (MMEs) for standardized reporting. The quality of each eligible study was evaluated using the Methodological Index for Non-Randomized Studies.
RESULTS
A total of 8 studies including 816 patients with a mean age of 43.8 years were eligible for inclusion. A mean of 610, 197, and 613 MMEs were prescribed to patients after arthroscopic procedures of the shoulder, knee, and hip, respectively. At final follow-up, 31%, 34%, and 64% of the prescribed opioids provided after shoulder, knee, and hip arthroscopy, respectively, still remained. The majority of patients (64%) were unaware of the appropriate disposal methods for surplus medication. Patients undergoing arthroscopic rotator cuff repair had the highest opioid consumption (471 MMEs), with 1 in 4 patients receiving a refill.
CONCLUSION
Opioids are being overprescribed for arthroscopic procedures of the shoulder, knee, and hip, with more than one-third of prescribed opioids remaining postoperatively. The majority of patients are unaware of the appropriate disposal techniques for surplus opioids. Appropriate risk stratification tools and evidence-based recommendations regarding pain management strategies after arthroscopic procedures are needed to help curb the growing opioid crisis.

In March 2020, the World Health Organization declared the spread of SARS-CoV-2 a global pandemic. To date, coronavirus disease-2019 (COVID-19) has spread to over 200 countries, leading to over 1.6 million cases and over 99,000 deaths. Given that there is neither a vaccine nor proven treatment for COVID-19, there is currently an urgent need for effective pharmacotherapy. To address the need for an effective treatment of SARS-CoV-2 during the worldwide pandemic, this systematic review of intravenous (IV) remdesivir was performed. Remdesivir, an anti-viral prodrug originally developed to treat Ebola virus disease, has shown broad spectrum activity against the Coronavirus family. A recent case report reported improvement of clinical symptoms with remdesivir in a patient with COVID-19. After conducting a systematic search of 18 clinical trial registries and three large scientific databases, we identified 86 potentially eligible items. Following removal of duplicates (n = 21), eligible studies were reviewed independently by two authors. After the first round of screening, inter-rater agreement was 98.5% (κ = 0.925). After the second round of full-text screening, inter-rater agreement was 100%. A total of seven ongoing and recruiting clinical trials of remdesivir (100-200 milligrams, intravenous [IV]) were included. We identified the following primary outcomes: patients discharged (n = 2); time to clinical status improvement (n = 2); improved O2 saturation (n = 2); body temperature normalization (n = 2); and clinical status (n = 1). Secondary outcomes in all identified studies included documentation of adverse events. Phase 3 trials are expected to be completed between April 2020-2023. Therefore, despite supportive data from in vitro and in vivo studies, the clinical effectiveness of IV remdesivir for treatment of COVID-19 and potential side effects remain incompletely defined in the human population.

BACKGROUND
Opioids have been proven effective in pain management, but overprescription can lead to addiction and abuse. Although current guidelines regarding opioid prescription for chronic and acute pain are available, they fail to address the use of opioids for pain management in traumatic injury patients who undergo operations. The primary objective of this study was to examine opioid prescribing practices for US adult trauma patients who require surgical management, based on prior history of opioid use, type of surgical practice, and age.
METHODS
PubMed and Cochrane Journals were used to identify relevant articles between October 2010 and December 29, 2020. Our primary outcome was discrepancies of morphine milligram equivalents (MMEs) prescribed to trauma patients. Significance was defined as p < 0.05.
RESULTS
Eleven studies on US trauma patients prescribed opioids were evaluated, creating a total of 30,249 patients stratified by prior opioid use, age, and race. Patterns seen among patients with prior opioid use include higher MMEs prescribed, lower likelihoods of opioid discontinuation, higher mortality rates, and higher complication rates. Orthopedic surgeons prescribed higher values of MMEs than nonorthopedic surgeons.
CONCLUSION
Higher incidences of opioid prescriptions are seen with orthopedic trauma surgery and prior opioid use by the patient. We recommend further development of national protocol implementation for acute pain management for the US trauma population.

Obstetrics and Gynecology Apr 2023To assess the amount of opioid medication used by patients and the prevalence of persistent opioid use after discharge for gynecologic surgery for benign indications.
OBJECTIVE
To assess the amount of opioid medication used by patients and the prevalence of persistent opioid use after discharge for gynecologic surgery for benign indications.
DATA SOURCES
We systematically searched MEDLINE, EMBASE, and ClinicalTrials.gov from inception to October 2020.
METHODS OF STUDY SELECTION
Studies with data on gynecologic surgical procedures for benign indications and the amount of outpatient opioids consumed, or the incidence of either persistent opioid use or opioid-use disorder postsurgery were included. Two reviewers independently screened citations and extracted data from eligible studies.
TABULATION, INTEGRATION, AND RESULTS
Thirty-six studies (37 articles) met inclusion criteria. Data were extracted from 35 studies; 23 studies included data on opioids consumed after hospital discharge, and 12 studies included data on persistent opioid use after gynecologic surgery. Average morphine milligram equivalents (MME) used in the 14 days after discharge were 54.0 (95% CI 39.9-68.0, seven tablets of 5-mg oxycodone) across all gynecologic surgery types, 35.0 (95% CI 0-75.12, 4.5 tablets of 5-mg oxycodone) after a vaginal hysterectomy, 59.5 (95% CI 44.4-74.6, eight tablets of 5-mg oxycodone) after laparoscopic hysterectomy, and 108.1 (95% CI 80.5-135.8, 14.5 tablets of 5-mg oxycodone) after abdominal hysterectomy. Patients used 22.4 MME (95% CI 12.4-32.3, three tablets of 5-mg oxycodone) within 24 hours of discharge after laparoscopic procedures without hysterectomy and 79.8 MME (95% CI 37.1-122.6, 10.5 tablets of 5-mg oxycodone) from discharge to 7 or 14 days postdischarge after surgery for prolapse. Persistent opioid use occurred in about 4.4% of patients after gynecologic surgery, but this outcome had high heterogeneity due to variation in populations and definitions of the outcome.
CONCLUSION
On average, patients use the equivalent of 15 or fewer 5-mg oxycodone tablets (or equivalent) in the 2 weeks after discharge after major gynecologic surgery for benign indications. Persistent opioid use occurred in 4.4% of patients who underwent gynecologic surgery for benign indications. Our findings could help surgeons minimize overprescribing and reduce medication diversion or misuse.
