Meta-Analysis
BACKGROUND
Osteoporosis (OP) results in an increased risk of fragility fractures, representing a major public health problem. In preventing OP, complementary and alternative medicine, such as acupuncture, was recommended because of the low efficiency and side effects of medications. Recently, there is insufficient evidence on electroacupuncture as an effective therapy for OP management. Hence, we evaluated the effectiveness of electroacupuncture for OP treatment.
METHODS
We conducted a systematic review and meta-analysis of clinical studies on patients with OP. Five databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, and Wanfang) were searched from the earliest publication date to March 12, 2020. Randomized controlled trials (RCTs) were included if electroacupuncture was applied as the sole treatment or as an adjunct to other treatments compared with medications in patients with OP. The measurement outcomes included serum aminoterminal propeptide of type I procollagen (PINP) and C-telopeptide of type I collagen (CTX) levels, bone mineral density (BMD) of lumbar, and visual analog scale scores for OP-related pain. Acupoints were extracted when available.
RESULTS
In total, 11 RCTs involving 731 participants were included for further meta-analysis. The meta-analysis showed that the use of electroacupuncture as a sole treatment or as an adjunct to other treatments could relieve OP-related pain compared with medications [mean difference (MD) = -0.58, 95% confidence interval (CI); MD = -0.97 to -0.19, P = .003, I2 = 88%; MD = -1.47, 95% CI = -2.14 to -0.79, P < .001, I2 = 96%). Meanwhile, the results showed a favorable effect of electroacupuncture on decreasing serum beta-CTX levels. However, there were no significant differences in serum PINP levels and BMD of lumbar. Shenshu (BL23) was the most frequent acupoint stimulation among these studies.
CONCLUSIONS
The application of electroacupuncture as an independent therapy or as an adjunct to other treatments might attenuate OP-related pain and serum beta-CTX levels. However, to overcome the methodological shortcomings of the existing evidence, due to a small size of samples and high risk of bias in these included RCTs, further rigorous studies are required.

Review
BACKGROUND/AIM
To define practical use and to specify the ideal method for monitoring the liver toxicity of MTX in the management of psoriasis.
OBJECTIVE
To systematically review the literature regarding treatment modalities with methotrexate (MTX) in psoriasis, risk of MTX-mediated liver fibrosis and monitoring of hepatic toxicity.
METHODS
A systematic literature search was carried out in Medline, Embase and Cochrane Library databases from 1980 to 2010 searching for randomized controlled trials and observational studies on methods of administering MTX in psoriasis and risk factors and assessment of liver toxicity. We limited the literature search to articles on human subjects over 19 years of age, articles in English or French on psoriasis and articles including psoriatic arthritis and original data.
RESULTS
Among 949 references identified, 23 published studies were included. There were no studies focusing directly on the question of MTX treatment modalities. Treatment outcome appears to be dose dependent. A single study in rheumatoid arthritis showed the slightly superior efficacy of subcutaneous administration vs. oral dosing with a similar safety profile. Combination with folic acid may decrease the efficacy of MTX while improving tolerability. The extreme variability of the incidence of hepatic fibrosis in the literature does not allow the risk of hepatic fibrosis to be quantified. Type 2 diabetes and obesity, were associated with a significant increased risk of liver fibrosis. Hepatitis B and C and alcohol consumption were associated with a modest and non-significant increased risk of liver fibrosis. Procollagen III for detection of hepatic fibrosis dosing was the most extensively validated method to monitor liver fibrosis showing a sensitivity of 77.3% and a specificity of 91.5%. The Positive Predictive Value and Negative Predictive Value fluctuated depending on the prevalence of hepatic fibrosis. The sensitivities of the FibroTest and the fibroscan were of 83 and 50%, respectively, with specific features amounting to 61 and 88% respectively.
CONCLUSIONS
Based on expert experience, the starting dose of MTX is between 5 and 10 mg/week for the first week. Fast dose escalation is recommended in order to obtain a therapeutic target dose of 15-25 mg/week. The maximum recommended dose is 25 mg/week. A folic acid supplement is necessary. The initiation of treatment by oral administration is preferred. In cases where inadequate response is obtained or in the event of poor gastrointestinal tolerance, subcutaneous dosing can be proposed at the same dose. Published data do not confirm the incidence of hepatic fibrosis. Type 2 diabetes and obesity appear to be significant risk factors in fibrosis. A combination of FibroTests and fibroscans together with measurement of the type III serum procollagen aminopeptide seem to be ideal method for monitoring liver toxicity.

OBJECTIVE
Reference intervals for plasma P1NP and β-CTX in children and adolescents from several studies have recently been published. The aim of this study was to combine the available data into a set of reference intervals for use in clinical laboratories.
DESIGN AND METHODS
A systematic literature search for primary studies reporting reference intervals for plasma P1NP and β-CTX in infants, children and adolescents using the Roche methods was carried out. Reference limits were extracted. For each year of age, mean upper and lower reference limits were calculated, weighted by the number of subjects in each study, and were plotted against age. Proposed reference limits were developed from the weighted mean data with age partitions determined pragmatically.
RESULTS
Reference limits for clinical use for females to 25 years and males to 18 years, based on the weighted mean reference data, are presented. Ten studies contributed to the pooled analysis. The proposed reference limits are identical for males and females <9 years age, prior to the pubertal growth spurt. For β-CTX, the weighted mean reference limits showed relatively constant values during the pre-pubertal years but a marked increase during puberty before a rapid decline towards adult values. Those for P1NP showed high values declining rapidly in the first 2 years of life, followed by a modest increase during early puberty. Limited published information for late adolescent and young adult subjects was noted.
CONCLUSIONS
The proposed reference intervals may be useful for clinical laboratories reporting these bone turnover markers measured by the Roche assays.

Meta-Analysis Review
ETHNOPHARMACOLOGICAL RELEVANCE
Liver fibrosis has been recognized as a major lesion of the liver that leads to liver cirrhosis at the end stage. Soshiho-tang (SST) has been used to improve liver fibrosis/cirrhosis by ameliorating fibrosis-specific markers. This study aimed to assess the efficacy of SST on liver fibrosis/cirrhosis through a systematic review of the literature and meta-analysis using animal models.
MATERIALS AND METHODS
Studies of SST treatment in liver fibrosis/cirrhosis-induced animal models were searched by electronic data bases. The quality of the studies included was assessed and the efficacy of SST was evaluated based on markers from liver tissues and serum.
RESULTS
Among the 838 studies identified in the literature search, 20 studies that met the inclusion criteria were included in the analysis. SST significantly reduced the elevated levels of fibrosis markers, such as the degree of fibrosis, hydroxyproline, hyaluronic acid, transforming growth factor-β1, and procollagen III in liver tissues, and aspartate aminotransferase, alanine aminotransferase, procollagen III, tissue inhibitor of metalloproteinase-1, and type IV collagen in the serum.
CONCLUSIONS
SST was effective in decreasing pathologically increased markers in animal models of liver fibrosis/cirrhosis. A larger-scale of animals, well-designed animal study is expected to improve the methodological quality, heterogeneity, and potential biases of the meta-analysis.

Meta-Analysis Review
OBJECTIVE
To investigate the differences in bone turnover between diabetic patients and controls.
DESIGN
A systematic review and meta-analysis.
METHODS
A literature search was conducted using the databases Medline at PubMed and EMBASE. The free text search terms 'diabetes mellitus' and 'bone turnover', 'sclerostin', 'RANKL', 'osteoprotegerin', 'tartrate-resistant acid' and 'TRAP' were used. Studies were eligible if they investigated bone turnover markers in patients with diabetes compared with controls. Data were extracted by two reviewers.
RESULTS
A total of 2881 papers were identified of which 66 studies were included. Serum levels of the bone resorption marker C-terminal cross-linked telopeptide (-0.10 ng/mL (-0.12, -0.08)) and the bone formation markers osteocalcin (-2.51 ng/mL (-3.01, -2.01)) and procollagen type 1 amino terminal propeptide (-10.80 ng/mL (-12.83, -8.77)) were all lower in patients with diabetes compared with controls. Furthermore, s-tartrate-resistant acid phosphatase was decreased in patients with type 2 diabetes (-0.31 U/L (-0.56, -0.05)) compared with controls. S-sclerostin was significantly higher in patients with type 2 diabetes (14.92 pmol/L (3.12, 26.72)) and patients with type 1 diabetes (3.24 pmol/L (1.52, 4.96)) compared with controls. Also, s-osteoprotegerin was increased among patients with diabetes compared with controls (2.67 pmol/L (0.21, 5.14)).
CONCLUSIONS
Markers of both bone formation and bone resorption are decreased in patients with diabetes. This suggests that diabetes mellitus is a state of low bone turnover, which in turn may lead to more fragile bone. Altered levels of sclerostin and osteoprotegerin may be responsible for this.

Meta-Analysis
Type 1 diabetes (T1D) is associated with impaired bone health and both osteocalcin (OCN) and procollagen type 1 amino terminal propetide (P1NP) (markers of bone formation) and C-terminal cross-linked telopeptide (CTX) (marker of bone resorption) are decreased in adult patients with T1D. We review the existing literature characterizing these bone turnover markers in children and adolescents with T1D and by meta-analysis examine whether alterations in OCN, P1NP, and CTX are evident and if potential changes correlate to the metabolic control (hemoglobin A1c, HbA1c). Systematic searches at MEDLINE and EMBASE were conducted in January 2018 identifying all studies describing OCN, P1NP, or CTX in children and adolescents with T1D. A total of 26 studies were included, representing data from more than 1000 patients with T1D. Pooled analyses of standard mean difference and summary effects analysis were performed when sufficient data were available. Pooled analysis revealed mean OCN to be significantly lower in children and adolescents with T1D compared to healthy controls (standard mean difference: -1.87, 95% confidence interval, CI: -2.83; -0.91) whereas both P1NP and CTX did not differ from the controls. Only data on OCN was sufficient to make pooled correlation analysis revealing a negative correlation between OCN and HbA1c (-0.31 95% CI: -0.45; -0.16). In conclusion, OCN is decreased in children and adolescents with T1D, whether CTX and P1NP are affected as well is unclear, due to very limited data available. New and large studies including OCN, P1NP, and CTX (preferably as z-scores adjusting for age variability) is needed to further elucidate the status of bone turnover in children and adolescents with T1D.

Percutaneous Vertebroplasty Combined with Zoledronic Acid in Treatment and Prevention of Osteoporotic Vertebral Compression Fractures: A Systematic Review and Meta-Analysis of Comparative Studies.
OBJECTIVE
This study was designed to help elucidate the benefits and advantages of vertebroplasty combined with zoledronic acid (ZOL) versus vertebroplasty alone, to provide clinical recommendations for the treatment of osteoporotic vertebral compression fractures (OVCFs) considering the current best-available evidence.
METHODS
We comprehensively searched PubMed, Embase, Web of Science, and the Cochrane Library and performed a systematic review and cumulative meta-analysis of all randomized controlled trials and retrospective comparative studies assessing these important indexes of 2 methods using Review Manager 5.4.
RESULTS
Four randomized controlled trials and 4 retrospective studies including 2335 cases were identified. Vertebroplasty combined with ZOL was associated with benefits from decreased pain (weighted mean difference [WMD] -0.43; 95% confidence interval [CI] -0.59 to -0.27; P < 0.05), increased function (WMD -4.94; 95% CI -6.13 to -3.75; P < 0.05), increased BMD of the vertebral body(WMD 0.85; 95% CI 0.30-1.40; P < 0.05) and of the proximal femoral neck (WMD 0.14; 95% CI 0.08-0.21; P < 0.05), fewer markers of bone metabolism (N-terminal molecular fragment: WMD -4.82; 95% CI -6.08 to -3.55; P < 0.05; procollagen type I N-terminal propeptide: WMD -17.31; 95% CI -18.04 to -16.58; P < 0.05; beta collagen degradation product: WMD -0.27; 95% CI -0.35 to -0.19; P < 0.05), and lower rate of refracture (1.54% and 12.6%; odds ratio 0.17; 95% CI 0.08-0.36; P < 0.05). Patients in the vertebroplasty combined with ZOL group had greater vertebral body height (WMD 2.17; 95% CI 0.72-3.62; P < 0.05) than in the vertebroplasty group, but no differences on Cobb angle were observed (WMD -1.18; 95% CI -2.47 to 0.10; P > 0.05).
CONCLUSIONS
Vertebroplasty combined with ZOL was superior to vertebroplasty alone in terms of BMD, bone metabolism makers, refracture rate, pain and function.

Meta-Analysis Review
PURPOSE
Parastomal hernia (PSH) is a common and serious complication in patients with enterostomy, but there is no current consensus for the risk factors for PSH from previous studies. Therefore, this study systematically analyzed the risk factors for PSH to provide a reference for prevention and treatment of this condition.
METHODS
Seven databases and 3 registers were systematically searched from database inception to January, 2021. Study quality was assessed by Newcastle-Ottawa Scale. Review Manager 5.3 software was used for statistical analysis. The data that could not be combined quantitatively were only analyzed qualitatively.
RESULTS
Sixteen studies with 2031 patients were included. Higher BMI (OR, 1.29; 95% CI,1.02-1.63), older age (OR, 1.04; 95% CI, 1.02-1.07), female (OR, 2.55; 95% CI,1.39-4.67), lager aperture size (OR, 2.8; 95%CI, 1.78-4.42), transperitoneal stoma creation (OR, 2.4; 95% CI, 1.33-4.35), and lager waist circumference (OR, 1.01; 95% CI,1.0-1.01) were significant risk factors for PSH. The laparoscopic approach was not a risk factor for PSH (OR, 2.09; 95% CI, 0.83-5.27). Other risk factors, including the thickness of abdominal subcutaneous fat, no mesh, a stoma not through the middle of the rectus abdominis, atrophy of left lower medial part of rectus abdominis, α1(III) procollagen expression level, emergency surgery, no preoperative stoma site marking, end colostomy, smoking, diabetes, peristomal infection, severe abdominal distention, severe cough, chronic obstructive pulmonary disease, operation time and hypertension, were significant on the multivariate analysis of each individual study.
CONCLUSIONS
The current available evidence showed that higher BMI, older age, female, larger aperture size, the creation of a transperitoneal stoma, and a larger waist circumference were independent risk factors for PSH. For factors without exact cutoff value, further explorations are needed in the future. In addition, reference to the limited number of studies in the pooled analysis, these factors still need to be interpreted carefully.

Meta-Analysis Review
People with psoriasis taking methotrexate may be at increased risk of developing liver fibrosis compared with the general population. Noninvasive methods of detecting fibrosis have been widely adopted but their clinical utility is uncertain. To evaluate the diagnostic accuracy of noninvasive methods to detect fibrosis compared with liver biopsy (reference standard) in people with psoriasis taking methotrexate. A systematic search using Ovid/Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library and Clinical Trials Register was performed. Diagnostic cohorts or case-control studies of adults taking or being considered for methotrexate therapy were considered. Study quality was evaluated using the Quality Assessment tool for Diagnostic Accuracy Studies (QUADAS-2). Pooled data analysis was performed using RevMan 5.1. Bayesian meta-analysis was conducted using Markov chain Monte Carlo simulation. Seventeen studies were included. Sensitivity and specificity were 38% and 83% for standard liver function tests (LFTs), 74% and 77% for procollagen-3 N-terminal peptide (P3NP), 60% and 80% for Fibroscan(®) (Echosens, France, www.echosens.com), and 55% and 49% for ultrasound. Confidence in these results is limited owing to low-quality data; old, small studies displayed significant selection bias and significant variation in the prevalence of fibrosis. No studies were identified evaluating recently developed markers. The clinical utility of LFTs, P3NP and liver ultrasound is poor. Therefore if these tests are used in isolation, a significant proportion of patients with liver fibrosis may remain unidentified. Larger prospective studies are required in this population to validate newer non-invasive methods.

Meta-Analysis
The current study presents a comprehensive systematic review and meta-analysis of randomized controlled trials (RCTs) on resveratrol and bone health biomarkers. PubMed, Scopus, and Web of Science (until September 2018) were searched to identify the potential RCTs with information on resveratrol supplementation and bone metabolism biomarkers. Mean differences (MD) were analyzed using a random-effects model. Pooling six RCTs (eight treatment arms with 264 subjects) together identified no significant reduction of serum Ca, osteocalcin, C-terminal telopeptide of type I collagen, and procollagen I N-terminal propeptide values after resveratrol supplementation over placebo treatment. However, a significant increase in serum alkaline phosphatase (ALP) (MD: 5.69 mg/mL, 95% CI: 3.58-7.80, I = 95.7%, P < 0.001) and bone alkaline phosphatase (BAP) (MD: 10.57 mmHg, 95% CI: 5.36-15.78, I = 99.2%, P < 0.001) values was observed after resveratrol treatment relative to placebo. The findings of this study indicate that resveratrol supplementation increased some key bone biomarkers, such as ALP and BAP. Further precise clinical trials of the effects of resveratrol supplementation on bone health should be conducted.
