Meta-Analysis
OBJECTIVE
Determine the relative effectiveness and safety profiles of percutaneous and minimally invasive interventions for chronic low back pain.
METHODS
A systematic search was performed for randomized controlled trials published in the past 20 years reporting on radiofrequency ablation of the basivertebral, disk annulus and facet nerve structures, steroid injection of the disk, facet joint, and medial branch, biological therapies, and multifidus muscle stimulation. Outcomes evaluated included Visual Analog Scale (VAS) pain scores, Oswestry Disability Index (ODI) scores, quality of life (SF-36 and EQ-5D) scores, and serious adverse event (SAE) rates. Basivertebral nerve (BVN) ablation was chosen as the subject of comparison to all other therapies using a random-effects meta-analysis.
RESULTS
Twenty-seven studies were included. BVN ablation was found to provide statistically significant improvements in VAS and ODI scores for 6-, 12- and 24-month follow-up ( P ≤0.05). Biological therapy and multifidus muscle stimulation were the only 2 treatments with both VAS and ODI outcomes not significantly different from BVN ablation at 6-, 12-, and 24-month follow-up. All outcomes found to be statistically significant represented inferior results to those of BVN ablation. Insufficient data precluded meaningful comparisons of SF-36 and EQ-5D scores. The SAE rates for all therapies and all reported time points were not significantly different from BVN ablation except for biological therapy and multifidus muscle stimulation at the 6-month follow-up.
CONCLUSIONS
BVN ablation, biological therapy, and multifidus stimulation all provide significant, durable improvements in both pain and disability compared with other interventions, which provided only short-term pain relief. Studies on BVN ablation reported no SAEs, a significantly better result than for studies of biological therapy and multifidus stimulation.

Meta-Analysis Review
BACKGROUND
Neisseria meningitidis is one of the most important causes of meningitis and pathogens-associated deaths in developing and developed countries. Effective anti-microbial agents are pivotal to treat and control N. meningitidis infections. The aim of the present study was to systematically review published studies on the antibiotic resistance of N. meningitidis in the last 20 years (2000-2020) in the world.
METHODS
Published researches were identified through a literature search using reputable databases including PubMed, Scopus, and Web of Science. Finally, 24 studies were included for a random-effects model meta-analysis.
RESULTS
The overall resistance to most commonly used antibiotics such as ceftriaxone, cefotaxime, ciprofloxacin and rifampin was low, ranging from 1 to 3.4%. However, non-sensitivity to penicillin, as the first-line antibiotic against N. meningitidis, was higher (27.2%). Altogether, the resistance to the first-line antibiotics (except penicillin) is still low indicating these drugs are effective against meningococcal meningitis. We also found a significant gap between MIC and disk diffusion for evaluating resistance to antibiotics in which disk diffusion overestimate the resistance rate.
CONCLUSIONS
To properly management and prevent the spread of N. miningitidis isolates resistant antibiotics, it is necessary to monitor the pattern of antibiotic susceptibility regionally and globally using the MIC methods.

Review
The emergence of polymyxin resistance, due to transferable mcr genes, threatens public and animal health as there are limited therapeutic options. As polymyxin is one of the last-line antibiotics, there is a need to contain the spread of its resistance to conserve its efficacy. Herein, we describe current and emerging polymyxin resistance diagnostics to inform faster clinical diagnostic choices. A literature search in diverse databases for studies published between 2016 and 2020 was performed. English articles evaluating colistin resistance methods/diagnostics were included. Screening resulted in the inclusion of 93 journal articles. Current colistin resistance diagnostics are either phenotypic or molecular. Broth microdilution is currently the only gold standard for determining colistin MICs (minimum inhibitory concentration). Phenotypic methods comprise of agar-based methods such as CHROMagar™ Col-APSE, SuperPolymyxin, ChromID Colistin R, LBJMR and LB medium; manual MIC-determiners viz., UMIC, MICRONAUT MIC-Strip and ComASP Colistin; automated antimicrobial susceptibility testing systems such as BD Phoenix, MICRONAUT-S, MicroScan, Sensititre and Vitek 2; MCR-detectors such as lateral flow immunoassay (LFI) and chelator-based assays including EDTA- and DPA-based tests, that is, combined disk test, modified colistin broth-disk elution (CBDE), Colispot, and Colistin MAC test as well as biochemical colorimetric tests, that is, Rapid Polymyxin NP test and Rapid ResaPolymyxin NP test. Molecular methods only characterize mobile colistin resistance; they include PCR, LAMP and whole-genome sequencing. Due to the faster turnaround time (≤3 h), improved sensitivity (84%-100%) and specificity (93.3%-100%) of the Rapid ResaPolymyxin NP test and Fastinov , we recommend this test for initial screening of colistin-resistant isolates. This can be followed by CBDE with EDTA or the LFI as they both have 100% sensitivity and a specificity of ≥94.3% for the rapid screening of mcr genes. However, molecular assays such as LAMP and PCR may be considered in well-equipped clinical laboratories.

Review
BACKGROUND
Retraction plays a vital role in optimizing the field of vision in minimal-access surgery. As such, a number of devices have been marketed to aid the surgeon in laparoscopic retraction. This systematic review explores the advantages and disadvantages of the different instruments in order to aid surgeons and their institutions in selecting the appropriate device. Primary outcome measures include operation time, length of stay, use of staff, patient morbidity, ease of use, conversion rates to open surgery, and cost.
METHODS
Systematic literature searches were performed in MEDLINE, EMBASE, The Cochrane Library, Current Controlled Trials, and ClinicalTrials.gov. The search strategy focused on studies testing a retraction device. The selection process was based on a predefined set of inclusion and exclusion criteria. Data were then extracted and analyzed.
RESULTS
Out of 1360 papers initially retrieved, 12 articles were selected for data extraction and analysis. A total of 10 instruments or techniques were tested. Devices included the Nathanson's liver retractor, liver suspension tape, the V-List technique, a silicone disk with or without a snake retractor, the Endoloop, the Endograb, a magnetic retractor, the VaroLift, a laparoscope holder, and a retraction sponge. None of the instruments reported were associated with increased morbidity. No studies found increased rates of conversion to open surgery. All articles reported that the tested instruments might spare the use of an assistant during the procedure. It was not possible to determine the impact on length of stay or operation time.
CONCLUSIONS
Each analyzed device facilitates retraction, providing a good field of view while allowing reduced staff numbers and minimal patient morbidity. Due to economic and environmental advantages, reusable devices may be preferable to disposable instruments, although the choice must be primarily based on clinical judgement.

Meta-Analysis
PURPOSE
To explore the current research about the role of optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) in dysthyroid optic neuropathy (DON).
METHODS
Studies in the literature that focused on OCT, OCTA and DON were retrieved by searching PubMed, EMBASE, Cochrane databases and Clinical Trial before 20 June 2023. The methodological quality was assessed using the Newcastle-Ottawa scale. The quantitative calculation was performed using Review Manager V.5.3.
RESULTS
Twelve studies met the eligibility criteria and were included. DON group presented lower macular ganglion cell complex in the overall, superior and inferior hemifields compared with the non-DON group. Furthermore, the ganglion cell layer and inner plexiform layer in DON group was thinner in contrast to the non-DON group. The optic nerve head vessel density was lower in the DON group than that in the non-DON group. A reduction of radial peripapillary capillary vessel density could be seen in the DON group than the non-DON group in overall, inside disc, peripapillary, superior-hemifield, temporal and nasal. Besides, the macular superficial retinal capillary layer of non-DON and DON is lower than the healthy control group.
CONCLUSIONS
This study supported the potential value of OCT and OCTA metrics as novel biomarkers of DON. Ophthalmologists should comprehensively consider the retinal structure and microvasculature in dealing with DON.
ETHICS AND DISSEMINATION
This systematic review included data from published literature and was exempt from ethics approval. Results would be disseminated through peer-reviewed publication and presented at academic conferences engaging clinicians.

Meta-Analysis
Facet tropism is recognized as the difference in the positioning of the facet joints in association with each other in the sagittal plane. This guides to an imbalanced biomechanical force over the facet joints and the intervertebral disc during rotation and other physiological activities. A systematic review and meta-analysis of Web of Science, EMBASE, PubMed, Cochrane Library, SCOPUS, and CINHAL from 2004 to 2021 to recognize the related research studies was performed. The data for meta-analysis were obtained from multiple studies to get the combined effect of the facet tropism on the lumbar disc herniation (LDH) and the degenerative lumbar spondylolisthesis (LDS). 117 articles were incorporated in the systematic review, where 41 studies were selected for meta-analysis, out of which 7 studies were found eligible as per the inclusion criteria. When degenerative lumbar spondylolisthesis was compared with the normal group, 95% CI was observed at 1.94 (1.59, 2.28). There was a comparison of disc herniation with the normal group in L4/L5, with a 95% CI of 0.60 (0.05, 1.14). The L5/S1 disc herniation was compared with the normal group and was found to be 0.21 (-0.48, 0.90). Therefore, it was observed that facet tropism is related to lumbar disc herniation and degenerative lumbar spondylolisthesis. Our meta-analysis demonstrated a unique link between the facet tropism and the lumbar disk degeneration along with degenerative lumbar spondylolisthesis.

Review
PURPOSE
Thoracic spinal stenosis (TSS) is a rare disease secondary to multiple pathological changes that differ in prevalence and clinical characteristics. The epidemiological characteristics of these pathologies are largely unknown due to the limited case samples and regional differences. Therefore, a systematic review was conducted to elucidate the prevalence and clinical characteristics of TSS.
METHODS
Case series and case reports on the ossification of the posterior longitudinal ligaments (OPLL), ossification of the ligamentum flavum (OLF) and thoracic disk herniation (TDH) were screened from PubMed, Embase and Web of Science databases and systematically reviewed. Epidemiological, demographic and segmental distribution data were extracted and analyzed.
RESULTS
A total of 129 studies including 1935 subjects were selected, of which 361 (18.7%) were diagnosed with OPLL, 804 (41.5%) with OLF, 143 (7.4%) with OPLL + OLF and 627 (32.4%) with TDH. Most reports were from China, Japan and USA. Thoracic OPLL occurred mostly at the middle-thoracic spine (43.4%), while OLF predominately occurred at the lower-thoracic spine (63.1%). TDH was mainly localized in the middle (46.0%) and lower-thoracic (50.3%) spine. Thirty-two studies involving 524 patients described tandem spinal stenosis, of which 52.1% had accompanying cervical diseases and 35.9% lumbar diseases.
CONCLUSIONS
There are significant differences in the age, sex and segment distribution characteristics of different pathologies leading to TSS. Tandem spinal stenosis is not uncommon and should be considered when diagnosing TSS. Our findings provide new insights into the prevalence and clinical characteristics of TSS and can help reduce misdiagnosis.

Introductionː Cervical disk arthroplasty is a potential alternative procedure to anterior cervical decompression and fusion for the treatment of cervical disk disease. The aim of the study was to perform a systematic literature review on long-term clinical and radiological outcomes after Bryan cervical disk arthroplasty.Material and Methodsː A systematic literature review was performed according to PRISMA guidelines via PubMed and Embase, Scopus, and the Cochrane Library database by using the following keywords: "Bryan prosthesis"; "cervical disk arthroplasty"; "outcomes"; and "long-term follow-up." Eight articles with at least 10 years of follow-up were considered for eligibility.Resultsː In total, 481 patients were enrolled in the studies. Because of the occurrence of multiple treated levels, 588 arthroplasties were performed, divided as follows: 12 C3/4 cervical disk arthroplasties (2.01%), 63 C4/5 (10.71%), 325 C5/6 (55.27%), and 188 C6/7 (31.97%). The mean preoperative cervical lordosis was 13.6 ± 9.3°, whereas the last follow-up value was 12.8 ± 8.7°. In the last follow-up, the mean segmental range of motion was 8.2 ± 3.3°.Discussion: Recent studies have suggested that cervical disk arthroplasty should be safely performed in healthy young patients with disk degeneration who may need future revision surgery. The results suggest that this procedure preserves native cervical spinal biomechanics at long-term follow-up with acceptable adjacent segments disease and periprosthetic ossifications.Conclusionsː Cervical disk arthroplasty has good long-term device survival, motility, adjacent segment degeneration, and clinical outcomes. Therefore, it represents a valid alternative for the treatment of cervical spine degenerative pathologies, especially in young patients.

Spine Jul 2023Systematic review and meta-analysis. (Meta-Analysis)
Meta-Analysis
STUDY DESIGN
Systematic review and meta-analysis.
OBJECTIVE
This study aimed to assess the incidence of heterotopic ossification (HO) 10 years after cervical disk replacement (CDR).
SUMMARY OF BACKGROUND DATA
HO is a common complication after CDR and may limit the range of motion of the artificial disk. As HO usually progresses slowly, a long-term follow-up is required to better understand its incidence. In recent years, the increasing number of original articles reporting 10-year outcomes gives us the opportunity to better understand the long-term incidence of HO.
MATERIALS AND METHODS
We searched PubMed, Medline, Embase, and Cochrane Library databases to identify eligible studies. The incidence of HO was pooled, and subgroup analysis was performed. Meta-regression analyses were conducted to identify factors contributing to heterogeneity.
RESULTS
Eleven studies with at least 10 years of follow-up comprising 1140 patients who underwent CDR were included. The pooled incidence of overall HO was 70% (95% CI, 60%-81%) at 10 years postoperatively, 60% (95% CI, 44%-75%) at five or six years postoperatively, and 50% (95% CI, 27%-72%) at one or two years postoperatively. The pooled incidence of severe HO (grade 3 or 4) was 37% (95% CI, 29%-45%), and mild HO (grade 1 to 2) was 30% (95% CI, 17%-44%) at 10 years of follow-up. Pooled range of motion decreased from 8.59° before surgery to 7.40° 10 years after surgery. Subgroup analysis showed that HO incidence differed according to the prosthesis type. The earlier publication was associated with a higher pooled incidence of severe HO in the meta-regression analysis.
CONCLUSIONS
This is the first meta-analysis providing detailed information on the pooled 10-year incidence of HO after CDR. The incidence of HO seems to increase with the length of follow-up.
