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.

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
BACKGROUND
The results from clinical trials have revealed that the effects of resveratrol supplementation on bone mineral density (BMD) and bone biomarkers are inconsistent. Our objective was to determine the effects of resveratrol supplementation on BMD and serum bone biomarkers.
METHODS
PubMed, Cochrane library, EMBASE, Web of science and Scopus were searched up to August 24, 2020. Two reviewers independently performed the articles search and screen according to defined selection criteria. The study quality of the randomized controlled trials (RCTs) was evaluated with the Cochrane scoring system. Heterogeneity among studies was examined by Cochrane Q test. Retrieved data were pooled after mean differences (MD) were computed between two groups for BMD and serum biomarkers. Subgroup analyses were performed to evaluate a potential difference in terms of dose of resveratrol and intervention duration. Sensitivity analysis was executed by omitting studies with imputed values in order to evaluate the influence of these studies on the overall results.
RESULTS
Ten eligible studies involving 698 subjects were included in this meta-analysis with 401 participants receiving resveratrol and 297 receiving placebo. Supplementation of resveratrol had no statistically significant effects on areal bone mineral density (aBMD) at lumbar spine (MD: -0.02, 95% CI: - 0.05, 0.01, p = 0.26, I = 6%), total hip BMD (MD: -0.01, 95% CI: - 0.04, 0.02, p = 0.65, I = 0%), and whole body BMD (MD: 0.00, 95% CI: - 0.02, 0.02, p = 0.74, I = 0%). Supplementation of resveratrol also did not result in significant change in bone serum markers, including serum alkaline phosphatase (ALP), bone alkaline phosphatase (BAP), osteocalcin (OCN), procollagen I N-terminal propeptide (PINP), C-terminal telopeptide of type I collagen (CTX) and parathyroid hormone (PTH). Subgroup analysis showed the effect of resveratrol supplementation on BMD and serum bone markers were similar in trails of different doses, intervention duration, and pathological conditions of the participants.
CONCLUSION
Resveratrol supplementation did not show any significant effect on BMD or serum bone markers with the current evidence. Further investigation with more well-organized multicentre randomized trial is warranted.

Nutrition Reviews Mar 2022Foods containing vitamin D reduce the deficiency of this vitamin and improve bone turnover.
CONTEXT
Foods containing vitamin D reduce the deficiency of this vitamin and improve bone turnover.
OBJECTIVE
To discuss effects of the intake of vitamin D-fortified foods in isolated form or associated with calcium on bone remodeling in postmenopausal women.
DATA SOURCES
PubMed, Lilacs, Scopus, and Bireme databases. OpenThesis and Google Scholar were searched as "grey literature". Medical subject headings or similar terms related to food fortified with vitamin D and bone in postmenopausal women were used.
DATA EXTRACTION
Information was collected on study methodology and characteristics of studied populations; dosage; the food matrix used as the fortification vehicle; duration of intervention; dietary intake; 25-hydroxyvitamin D [25(OH)D] levels; serum parathyroid hormone (PTH) concentrations; bone resorption and/or formation markers (ie, carboxy terminal cross-linked telopeptide of type I collagen [CTX], tartrate-resistant acid phosphatase isoform 5b [TRAP5b], and procollagen type 1 N-terminal propeptide [P1NP]); main results; and study limitations.
DATA ANALYSIS
Five randomized controlled trials involving postmenopausal women were included. The mean ages of participants ranged from 56.1 to 86.9 years. Daily consumption of soft plain cheese fortified with 2.5 µg of vitamin D3 and 302 mg of calcium for 4 weeks resulted in a mean increase of 0.8 ng/mL in 25(OH)D and 15.9 ng/mL in P1NP levels compared with baseline, and decreased CTX, TRAP5b, and PTH values. A similar intervention for 6 weeks, using fortified cheese, showed a reduction only in TRAP5b values (-0.64 U/L). Yogurt fortified with 10 µg of vitamin D3 and 800 mg of calcium did not change P1NP values after 8 weeks of intervention, but was associated with decreases of 0.0286 ng/mL and 1.06 U/L in PTH and TRAP5b, respectively. After 12 weeks of eating the fortified yogurt, 25(OH)D levels increased by a mean of 8.8 ng/mL and PTH levels decreased in by a mean of 0.0167 ng/mL.
CONCLUSIONS
The interventions contributed toward the improvement of the bone resorption process but not to the bone formation process in postmenopausal women.

Comparative Study Meta-Analysis
OBJECTIVE
Physical exercise has obvious effects on bone loss, pain relief, and improvement of bone metabolism indexes in patients with osteoporosis, but currently lacks sufficient evidence. The aim of this systematic review and meta-analysis was to synthesize and present the best available evidence on the effectiveness and safety of exercises in the treatment of primary osteoporosis.
METHODS
Publications pertaining to the effectiveness of exercise on bone mineral density (BMD), visual analog scores (VAS), and biochemical markers of bone metabolism in primary osteoporosis (POP) from PubMed, Cochrane Library, Embase, VIP, CNKI, and Wanfang Database were retrieved from their inception to April 2020.
RESULTS
A total of 20 studies with 1824 participants were included. The results of the meta-analysis revealed that exercise therapy for lumbar spine and femoral neck BMD is statistically different from conventional therapy (lumbar spine BMD: SMD = 0.78, 95%CI: 0.46, 1.10, P < 0.00001, I = 85%; femoral neck BMD (SMD = 0.80, 95%CI: 0.34, 1.27, P = 0.0007, I = 88%), exercise therapy can significantly increase the lumbar spine BMD of patients with OP, especially in lumbar spine2-4 BMD (SMD = 0.47; 95%CI: 0.20, 0.75; P = 0.0008; I = 69%). Compared with conventional treatment, kinesitherapy also has significant differences in alleviating the pain of POP patients (SMD = -1.39, 95%CI: -2.47,-0.31, P = 0.01, I = 97%). Compared with conventional therapy, kinesitherapy has no significant difference in improving biochemical markers of bone metabolism such as bone glaprotein (BGP) (SMD = 2.59, 95%CI:0.90, 4.28, P = 0.003, I = 98%), N-terminal pro peptide of type I procollagen (PINP) (SMD = 0.77, 95%CI: -0.44 to 1.98, P = 0.21, I = 95%), serum phosphorus (SMD = 0.04, 95%CI: -0.13, 0.22, P = 0.61, I = 30%), alkaline phosphatase (ALP) (SMD = -0.08, 95%CI: -0.44, 0.27, P = 0.64, I = 76%), and serum calcium (SMD = 0.12, 95%CI: -0.18, 0.43, P = 0.42, I = 63%) in POP patients.
CONCLUSIONS
Kinesitherapy significantly improved lumbar spine and femoral neck BMD, and relieve the pain of patients in the current low-quality evidence. Additional high-quality evidence is required to confirm the effect of exercise therapy on the biochemical markers of bone metabolism in POP patients.

BACKGROUND
Biochemical markers of bone turnover (BTMs), such as the bone alkaline phosphatase (bALP), procollagen type I N propeptide (PINP), serum cross-linked C-telopeptides of type I collagen (bCTx), and urinary cross-linked N-telopeptides of type I collagen (NTx), are used to manage therapy monitoring in osteoporotic patients. This systematic review analyzed the potential of these BMTs in predicting the clinical outcomes in terms of BMD, t-score, rate of fractures, and adverse events during the therapy setting in postmenopausal osteoporosis.
METHODS
All randomized clinical trials (RCTs) reporting data on biomarkers for postmenopausal osteoporosis were accessed. Only articles reporting quantitative data on the level of biomarkers at baseline and on the outcomes of interest at the last follow-up were eligible.
RESULTS
A total of 36,706 patients were retrieved. Greater values of bALP were associated with a greater rate of vertebral (P = 0.001) and non-vertebral fractures (P = 0.0001). Greater values of NTx at baseline were associated with a greater rate of adverse events at the last follow-up (P = 0.02). Greater values of CTx at baseline were associated with a greater rate of adverse events leading to discontinuation (P = 0.04), gastrointestinal adverse events (P = 0.0001), musculoskeletal adverse events (P = 0.04), and mortality (P = 0.04). Greater values of PINP at baseline were associated with greater rates of gastrointestinal adverse events (P = 0.02) at the last follow-up.
CONCLUSION
The present analysis supports the adoption of BMTs during pharmacological therapy setting of patients suffering from osteoporosis.

BACKGROUND
Biochemical markers of bone turnover (BTMs), such as bone alkaline phosphatase (bALP), procollagen type I N propeptide (PINP), serum cross-linked C-telopeptides of type I collagen (bCTx), and urinary cross-linked N-telopeptides of type I collagen (NTx), are commonly used for therapy monitoring purposes for osteoporotic patients. The present study evaluated the potential role of BTMs as therapy monitoring.
METHODS
All randomized clinical trials (RCTs) comparing two or more pharmacological treatments for postmenopausal osteoporosis were accessed. Only studies that reported the value of bALP, PINP, bCTx, and NTx at last follow-up were included. A multivariate analysis was performed to assess associations between these biomarkers and clinical outcomes and rate of adverse events in patients with postmenopausal osteoporosis. A multiple linear model regression analysis through the Pearson product-moment correlation coefficient was used.
RESULTS
A total of 16 RCTs (14,446 patients) were included. The median age was 67 years, and the median BMI 25.4 kg/m. The median vertebral BMD was 0.82, hip BMD 0.79, and femur BMD 0.64 g/cm. The ANOVA test found optimal within-group variance concerning mean age, body mass index, and BMD. Greater bALP was associated with lower femoral BMD (P = 0.01). Greater NTx was associated with a greater number of non-vertebral fractures (P = 0.02). Greater NTx was associated with greater rate of therapy discontinuation (P = 0.04). No other statistically significant associations were detected.
CONCLUSION
Our analysis supports the adoption of BTMs in therapy monitoring of osteoporotic patients.

Clinical efficacy of zoledronic acid combined with percutaneous kyphoplasty in the prevention and treatment of osteoporotic vertebral compression fracture: A systematic review and meta-analysis.
OBJECTIVE:
The aim of this study is to investigate the clinical efficacy of zoledronic acid (ZOL) in the treatment and prevention of osteoporotic vertebral compression fractures (OVCF) after percutaneous kyphoplasty (PKP) for elderly patients.
METHODS:
The PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and Embase were investigated through June 2020. All randomized controlled trials (RCT) involving ZOL injections for OVCF were enrolled. Outcome indicators included the bone mineral density (BMD), Visual Analog Scale (VAS), recompression vertebral fracture (RVF), Oswestry Disability Index (ODI), and bone metabolism (Procollagen type I N-terminal propeptide [PINP] and βcross-linked C-telopeptide of type I collagen [β-CTX]), bone cement leakage. Review Manager 5.3 was used to analyze these indicators.
RESULTS:
In this study, (1).. Eight studies had met the eligibility criteria, a total of 578 participants were involved (285 and 293 in the experimental (ZOL) group and control [no ZOL] group, respectively). (2).. The BMD scores of patients with OVCF in the experimental group were significantly higher than that in the control group ( < .05). The VAS scores were significantly different between the 2 groups at the 6, 12 months follow-up ( < .05). After PKP operation, ZOL injections reduced the rate of RVF ( < .05). In the comparison of ODI scores, the experimental group improved compared with the control group ( < .05). Respectively, the bone metabolism of patients with OVCF after ZOL was better than that of patients in control group ( < .05).
CONCLUSION:
Zoledronic acid had a significant effect on the treatment and prevention of OVCF in elderly osteoporotic patients after PKP. Due to the limited quality and data, more high-quality studies are needed to confirm the results of this meta-analysis.

BACKGROUND AND AIMS
The rising incidence of chronic liver disease (CLD) has increased the need for early recognition. This systematic review assesses the diagnostic accuracy of the enhanced liver fibrosis (ELF) test in cases of advanced fibrosis and cirrhosis due to multiple etiologies in at-risk populations.
METHODS
Studies evaluating the ELF accuracy in identifying advanced fibrosis or cirrhosis, defined as METAVIR stage F ≥ 3 and F = 4 or equivalent, in patients with non-alcoholic fatty liver disease (NAFLD), alcohol liver disease (ALD), or viral hepatitis were included. Liver biopsy was used as the reference standard. Medline and Embase databases were searched. The QUADAS-2 tool was used as a framework to assess risk of bias and applicability. The area under the receiver operator curve (AUROC) was extracted as a summary measure of diagnostic accuracy.
RESULTS
Thirty-six studies were included: 11 hepatitis C, 4 hepatitis B, 9 NAFLD, 2 ALD, and 10 mixed. The ELF test showed good diagnostic performance in detecting advanced fibrosis in patients with viral hepatitis (AUROC 0.69 to 0.98) and excellent performance in NAFLD (AUROC 0.78 to 0.97) and ALD (AUROC from 0.92 to 0.94). There is also evidence of good diagnostic performance for detecting cirrhosis in patients with viral hepatitis (AUROC 0.63 to 0.99), good performance in NAFLD (AUROC 0.85 to 0.92), and excellent performance in patients with ALD (AUROC 0.93 to 0.94).
CONCLUSION
This systematic review supports the use of the ELF test across a range of CLD as a possible alternative to liver biopsy in selected cases.

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.
