A Meta-Analysis of Complication Rates Among Different SMAS Facelift Techniques

AbstractBackgroundSub-superficial musculo-aponeurotic system (SMAS) rhytidectomy techniques are considered to have a higher complication profile, especially for facial nerve injury, compared with less invasive SMAS techniques. This results in surgeons avoiding sub-SMAS dissection.ObjectivesThe authors sought to aggregate and summarize data on complications among different SMAS facelift techniques.MethodsA broad systematic search was performed. All included studies: (1) described a SMAS facelifting technique categorized as SMAS plication, SMASectomy/imbrication, SMAS flap, high lateral SMAS flap, deep plane, and composite; and (2) reported the number of postoperative complications in participants. Meta-analysis was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.ResultsA total 183 studies were included. High lateral SMAS (1.85%) and composite rhytidectomy (1.52%) had the highest rates of temporary nerve injury and were the only techniques to show a statistically significant difference compared with SMAS plication (odds ratio [OR] = 2.71 and 2.22, respectively, P < 0.05). Risk of permanent injury did not differ among techniques. An increase in major hematoma was found for the deep plane (1.22%, OR = 1.67, P < 0.05) and SMAS imbrication (1.92%, OR = 2.65, P < 0.01). Skin necrosis was higher with the SMAS flap (1.57%, OR = 2.29, P < 0.01).ConclusionsThere are statistically significant differences in complication rates between SMAS facelifting techniques for temporary facial nerve injury, hematoma, seroma, necrosis, and infection. Technique should be selected based on quality of results and not the complication profile.Level of Evidence: 2

Abstract Background Acupuncture for post-stroke depression (PSD) has been evolving, but uncertainty remains. To assess the existing evidence from randomized clinical trials (RCTs) of acupuncture for PSD, we sought to draw conclusions by synthesizing RCTs. Methods An exhaustive literature search was conducted in seven electronic databases from their inception dates to April 19, 2020, to identify systematic reviews (SRs) and meta-analyses (MAs) on this topic. The primary RCTs included in the SRs/MAs were identified. We also conducted a supplementary search for RCTs published from January 1, 2015, to May 12, 2020. Two reviewers extracted data separately and pooled data using RevMan 5.3 software. The quality of evidence was critically appraised with the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) system. Results A total of 17 RCTs involving 1402 patients were included. Meta-analysis showed that participants who received a combination of acupuncture and conventional treatments exhibited significantly lower scores on the HAM-D17, HAM-D24 and HAM-D (MD, − 5.08 [95% CI, − 6.48 to − 3.67], I2 = 0%), (MD, − 9.72 [95% CI, − 14.54 to − 4.91], I2 = 65%) and (MD, − 2.72 [95% CI, − 3.61 to − 1.82], respectively) than those who received conventional treatment. However, there was no significant difference in acupuncture versus antidepressants in terms of the 17-item, 24-item and HAM-D scales (MD, − 0.43 [95% CI, − 1.61 to 0.75], I2 = 51%), (MD, − 3.09 [95% CI, − 10.81 to 4.63], I2 = 90%) and (MD, − 1.55 [95% CI, − 4.36 to 1.26], I2 = 95%, respectively). For adverse events, acupuncture was associated with fewer adverse events than antidepressants (RR, 0.16 [95% CI, 0.07 to 0.39], I2 = 35%), but there was no significant difference in the occurrence of adverse events between the combination of acupuncture and conventional treatments versus conventional treatments (RR, 0.63 [95% CI, 0.21 to 1.83], I2 = 38%). The quality of evidence was low to very low due to the substantial heterogeneity among the included studies. Conclusions The current review indicates that acupuncture has greater effect on PSD and better safety profile than antidepressants, but high-quality evidence evaluating acupuncture for PSD is still needed.

ABSTRACT BACKGROUND Anterior cervical discectomy and fusion (ACDF) is being increasingly offered on an outpatient basis. However, the safety profile of outpatient ACDF remains poorly defined. OBJECTIVE To review the medical literature on the safety of outpatient ACDF. METHODS We systematically reviewed the literature for articles published before April 1, 2018, describing outpatient ACDF and associated complications, including incidence of reoperation, stroke, thrombolytic events, dysphagia, hematoma, and mortality. A random-effects analysis was performed comparing complications between the inpatient and outpatient groups. RESULTS We identified 21 articles that satisfied the selection criteria, of which 15 were comparative studies. Most of the existing studies were retrospective, with a lack of level I or II studies on this topic. We found no statistically significant difference between inpatient and outpatient ACDF in overall complications, incidence of stroke, thrombolytic events, dysphagia, and hematoma development. However, patients undergoing outpatient ACDF had lower reported reoperation rates (P < .001), mortality (P < .001), and hospitalization duration (P < .001). CONCLUSION Our meta-analysis indicates that there is a lack of high level of evidence studies regarding the safety of outpatient ACDF. However, the existing literature suggests that outpatient ACDF can be safe, with low complication rates comparable to inpatient ACDF in well-selected patients. Patients with advanced age and comorbidities such as obesity and significant myelopathy are likely not suitable for outpatient ACDF. Spine surgeons must carefully evaluate each patient to decide whether outpatient ACDF is a safe option. Higher quality, large prospective randomized control trials are needed to accurately demonstrate the safety profile of outpatient ACDF.

Purpose Visit time is a crucial aspect of patient–physician interaction; its inadequacy can negatively impact the efficiency of treatment and diagnosis. In addition, visit time is a fundamental demand of patients, and it is one of the rights of every patient. The purpose of this paper is to determine factors influencing the consultation length of physicians and to compare consultation length in different countries. Design/methodology/approach MEDLINE (PubMed), Web of Science, Cochrane, ProQuest, Scopus, and Google Scholar were searched. In addition, references of references were checked, and publication lists of individual scholars in the field were examined. We used data sources up to June 2018, without language restriction. We used a random-effects model for the meta-analyses. Meta-analyses were conducted using Comprehensive Meta-Analysis Version (CMA) 3.0. Findings Of 16,911 identified studies, 189 studies were assessed of which 125 cases (67 percent) have been conducted in the USA. A total of 189 studies, 164 (86.77 percent) involved face-to face-consultations. The effects of three variables, physician gender, patient gender, and type of consultation were analyzed. According to moderate and strong evidence studies, no significant difference was found in the consultation lengths of female and male doctors (Q=42.72, df=8, I2=81.27, p=0.891) and patients’ gender (Q=55.98, df=11, I2=80.35, p=0.314). In addition, no significant difference was found in the telemedicine or face-to-face visits (Q=41.25, df=5, I2=87.88, p=0.170). Originality/value In this systematic review and meta-analysis, all of physicians’ visits in 34 countries were surveyed. The evidence suggests that specified variables do not influence the length of consultations. Good relationship is essential to a safe and high-quality consultation and referral process. A high-quality consultation can improve decisions and quality of visits, treatment effectiveness, efficiency of service, quality of care, patient safety and physician and patient satisfaction.

This systematic review examines the efficacy of oral ginger for dysmenorrhea. Key biomedical databases and grey literature were searched. We included randomized controlled trials comparing oral ginger against placebo or active treatment in women with dysmenorrhea. Six trials were identified. Two authors independently reviewed the articles, extracted data, and assessed risk of bias. Discrepancies were resolved by consensus with a third reviewer. We completed a narrative synthesis of all six studies and exploratory meta-analyses of three studies comparing ginger with placebo and two studies comparing ginger with a nonsteroidal anti-inflammatory drug (NSAID). Ginger appeared more effective for reducing pain severity than placebo. The weighted mean difference on a 10 cm visual analogue scale was 1.55 cm (favoring ginger) (95% CI 0.68 to 2.43). No significant difference was found between ginger and mefenamic acid (an NSAID). The standardized mean difference was 0 (95% CI −0.40 to 0.41). Available data suggest that oral ginger could be an effective treatment for menstrual pain in dysmenorrhea. Findings, however, need to be interpreted with caution because of the small number of studies, poor methodological quality of the studies, and high heterogeneity across trials. The review highlights the need for future trials with high methodological quality.

OBJECTIVE Cervical spondylotic myelopathy usually presents in the 5th decade of life or later but can also present earlier in patients with congenital spinal stenosis. As life expectancy continues to increase in the United States, the preconceived reluctance toward operating on the elderly population based on older publications must be rethought. It is a known fact that outcomes in the elderly cannot be as robust as those in the younger population. There are no publications with detailed meta-analyses to determine an acceptable level of outcome in this population. In this review, the authors compare elderly patients older than 75 years to a nonelderly population, and they discuss some of the relevant strategies to minimize complications. METHODS In accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, the authors performed a PubMed database search to identify English-language literature published between 1995 and 2015. Combinations of the following phrases that describe the age group (“elderly,” “non-elderly,” “old,” “age”) and the disease of interest as well as management (“surgical outcome,” “surgery,” “cervical spondylotic myelopathy,” “cervical degenerative myelopathy”) were constructed when searching for relevant articles. Two reviewers independently assessed the outcomes, and any disagreement was discussed with the first author until it was resolved. A random-effects model was applied to assess pooled data due to high heterogeneity between studies. The mean difference (MD) and odds ratio were calculated for continuous and dichromatic parameters, respectively. RESULTS Eighteen studies comprising elderly (n = 1169) and nonelderly (n = 1699) patients who received surgical treatment for cervical spondylotic myelopathy were included in this meta-analysis. Of these studies, 5 were prospective and 13 were retrospective. Intraoperatively, both groups required a similar amount of operation time (p = 0.35). The elderly group had lower Japanese Orthopaedic Association (JOA) scores (MD −1.36, 95% CI −1.62 to −1.09; p < 0.00001) to begin with compared with the nonelderly group. The nonelderly group also had a higher postoperative JOA score (MD −1.11, 95% CI −1.44 to −0.79; p < 0.00001), therefore demonstrating a higher recovery rate from surgeries (MD −11.98, 95% CI −16.16 to −7.79; p < 0.00001). The length of stay (MD 4.14, 95% CI 3.54–4.73; p < 0.00001) was slightly longer in the elderly group. In terms of radiological outcomes, the elderly group had a smaller postoperative Cobb angle but a greater increase in spinal canal diameter compared with the nonelderly group. The complication rates were not significant. CONCLUSIONS Cervical myelopathy is a disease of the elderly, and age is an independent factor for recovery from surgery. Postoperative and long-term outcomes have been remarkable in terms of improvement in mobility and independence requiring reduced nursing care. There is definitely a higher potential risk while operating on the elderly population, but no significant difference in the incidence of postoperative complications was noted. Withholding surgery from the elderly population can lead to increased morbidity due to rapid progression of symptoms in addition to deconditioning from lack of mobility and independence. Reduction in operative time under anesthesia, lower blood loss, and perioperative fluid management have been shown to minimize the complication rate. The authors request that neurosurgeons weigh the potential benefit against the risks for every patient before withholding surgery from elderly patients.

Abstract INTRODUCTION Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent surgical procedures and is used to treat several cervical spinal pathologies, including herniated discs, degenerative disc disease, and spondylosis. With the increasing prevalence of ACDF procedures, this procedure has become an excellent target for clinical optimization. Indeed, in recent years, ACDF has become increasingly offered on an outpatient basis. To date, the incidence and dynamics of perioperative complications and safety surrounding outpatient ACDF remain poorly resolved. METHODS We systematically reviewed the literature for articles published by April 2018 describing outpatient ACDF and associated complications, including incidence of reoperation, stroke, thrombolytic events, dysphagia, hematoma, and mortality. A random-effects analysis was performed comparing overall and specific complications between the inpatient and outpatient ACDF groups. RESULTS We identified 21 articles that satisfied the selection criteria, of which 15 were comparative studies. Most of the existing studies were retrospective, with a lack of level I or II studies on this topic. We found no statistically significant difference between inpatient and outpatient ACDF in overall complications, incidence of stroke, thrombolytic events, dysphagia, and hematoma development. However, patients undergoing outpatient ACDF had lower reported reoperation rates (P < .001), mortality (P < .001), and hospitalization duration (P < .001). CONCLUSION Our meta-analysis indicates that there is a lack of high level of evidence studies regarding the safety of outpatient ACDF. However, the existing literature suggests that outpatient ACDF can be safe, with low complication rates comparable to inpatient ACDF in well-selected patients. Patients with advanced age and comorbidities such as obesity and significant myelopathy are likely not suitable for outpatient ACDF. Spine surgeons must carefully evaluate each patient to decide whether outpatient ACDF is a safe option.

The Impact

A cumulative review with a systematic approach aimed to provide a comparison of studies’ investigating the possible impact of the active form of vitamin D3, calcitriol (CTL), on the tooth movement caused by orthodontic forces (OTM) by evaluating the quality of evidence, based on collating current data from animal model studies, in vivo cell culture studies, and human clinical trials. Methods: A strict systematic review protocol was applied following the application of the International Prospective Register of Systematic Reviews (PROSPERO). A structured search strategy, including main keywords, was defined during detailed search with the application of electronic database systems: Medline/Pubmed, EMBASE, Scopus, Web of Science, and PsycINFO. In addition, a search was carried out with the use of ClinicalTrials.gov search in order to include ongoing or recently completed trials. The Oxford Level of Evidence and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was utilized to critically evaluate the risk of bias and relative quality of studies included. Meta-analysis with the use of RevMan5 software, random effect, and inverted variable method allowed the quantification of cumulative results. Results: Twenty-seven studies were identified which fulfilled inclusion criteria, including two clinical studies. The assessed level of evidence was variable and inconsistent, predominantly being moderate or low due to a significant difference in study design, sample size, and study protocols. Data synthesis rendered from meta-analysis involving various CTL doses demonstrated slight discrepancies in tooth movement between control and experimental groups (mean difference = 0.27; 95% CI: 0.01–0.53, std mean difference = 0.49; 95% CI: 0.09–0.89), as well as relatively moderate heterogenicity. Conclusions: Although it has been suggested that CTL could accelerate OTM in animal studies and clinical context, these scarce data were supported by a low level of evidence and the studies were carried out using inadequate sample size. Well-powered RCT studies would help to overcome the lack of robustness of the research.

Botulinum Toxin Injections

Recently, Schulze and colleagues (2021) and we (Coles, Larsen, Kuribayashi, & Kuelz, 2019) published two separate meta-analyses examining whether glabellar-region botulinum toxin injections can decrease depression. Both meta-analysis teams reviewed similar studies; discussed similar mechanisms-of-action; observed unexpectedly large effect sizes; observed asymmetry in funnel plot distributions; and acknowledged that it is difficult to blind participants. Yet, our two teams came to starkly different conclusions. Whereas Schulze and colleagues concluded that the treatment reaches rigorous “1a level of evidence” standards (p. 338), we concluded the opposite: that the claim is “not yet well substantiated by a credible balance of evidence” (p. 11). In this Letter to the Editor, we clarify why we believe that a more careful consideration of the quality of the evidence, potential costs, and potential benefits is necessary before promoting botulinum toxin as an off-label treatment for depression.
