Meta-Analysis Review
PURPOSE
The great spatial and temporal resolution of positron emission tomography might provide the answer for patients with primary hyperparathyroidism (pHPT) and non-localized parathyroid glands. We performed a systematic review of the evidence regarding all investigated tracers.
METHODS
A study was considered eligible when the following criteria were met: (1) adults ≥17 years old with non-familial pHPT, (2) evaluation of at least one PET isotope, and (3) post-surgical and pathological diagnosis as the gold standard. Performance was expressed in sensitivity and PPV.
RESULTS
Twenty-four papers were included subdivided by radiopharmaceutical: 14 studies investigated L-[C]Methionine (11C-MET), one [C]2-hydroxy-N,N,N-trimethylethanamium (11C-CH), six 2-deoxy-2-[F]fluoro-D-glucose (18F-FDG), one 6-[F] fluoro-L-DOPA (18F-DOPA), and three N-[(F)Fluoromethyl]-2-hydroxy-N,N-dimethylethanaminium (18F-FCH). The 14 studies investigating MET included a total of 327 patients with 364 lesions. Sensitivity for the detection of a lesion in the correct quadrant had a pooled estimate of 69 % (95 % CI 60-78 %). Heterogeneity was overall high with I of 51 % (p = 0.01) for all 14 studies. Pooled PPV ranged from 91 to 100 % with a pooled estimate of 98 % (95 % CI 96-100 %). Of the other investigated tracers, 18-FCH seems the most promising with high diagnostic performance.
CONCLUSIONS
The results of our meta-analysis show that 11C-MET PET has an overall good sensitivity and PPV and may be considered a reliable second-line imaging modality to enable minimally invasive parathyroidectomy. Our literature review suggests that 18F-FCH PET may produce even greater accuracy and should be further investigated using both low-dose CT and MRI for anatomical correlation.

Meta-Analysis
PURPOSE
To evaluate the diagnostic accuracy of near-infrared autofluorescence-based identification in the identification of parathyroid glands during thyroidectomy or parathyroidectomy.
METHODS
The clinical studies were retrieved from PubMed, the Cochrane Central Register of Controlled Trials, Embase, Web of Science, SCOPUS, and Google Scholar. The study protocol was registered on Open Science Framework ( https://osf.io/um8rj/ ). The search period ranged from the date of each database's inception to May 2021. Cohort studies dealing with patients of whom parathyroid glands were detected by near-infrared autofluorescence and confirmed clinically or pathologically during thyroidectomy or parathyroidectomy were included. Editorials, letters, "how-I-do-it" descriptions, other site head and neck tumors, and articles with lack of diagnostic identification data were excluded. True positive, true negative, false positive, and false negative were extracted. The QUDAS ver. 2 was used to evaluate the methodological quality.
RESULTS
Seventeen studies with 1198 participants were evaluated in this analysis. Near-infrared autofluorescence-based identification of parathyroid glands showed a diagnostic odds ratio of 228.8759 (95% confidence interval, 134.1099; 390.6063). The area under the summary receiver operating characteristic curve was 0.967. The sensitivity, specificity, negative predictive value, and positive predictive value were 0.9693 (0.9491; 0.9816), 0.9248 (0.8885; 0.9499), 0.9517 (0.8981; 0.9778), and 0.9488 (0.9167; 0.9689), respectively. Subgroup analyses were performed to compare two autofluorescence detection methods, because there was high heterogeneity in the outcomes. The diagnostic accuracy was higher in probe-based detection than in image-based detection.
CONCLUSIONS
Near-infrared autofluorescence-based identification is valuable for identifying the parathyroid glands of patients during thyroidectomy or parathyroidectomy.

Meta-Analysis Review
BACKGROUND
Chronic kidney disease-mineral and bone disorders (CKD-MBD) have been associated with poor health outcomes, including diminished quality and length of life. Standard management for CKD-MBD includes phosphate restricted diet, vitamin D and phosphate binders. Persistently elevated parathyroid hormone levels may require the addition of cinacalcet hydrochloride (cinacalcet), which sensitizes calcium receptors in the parathyroid gland.
PURPOSE
The objective of this systematic review is to compare, in patients with CKD-MBD the effect of cinacalcet versus standard treatment on patient-important outcomes, including parathyroidectomy, fractures, hospitalizations due to cardiovascular events, cardiovascular mortality, all-cause mortality, and intermediate outcomes, in particular Kidney Disease Outcome Quality Initiative targets.
METHODS
Data sources included MEDLINE, EMBASE, the Cochrane Register of Controlled Trials and Web of Science from 1996 to June 2015. Teams of two reviewers, independently and in duplicate, screened titles and abstracts and potentially eligible full text reports to determine eligibility, and subsequently abstracted data and assessed risk of bias in eligible trials. We calculated the effect estimates (risk ratios or mean differences) and 95% confidence intervals, as well as statistical measures of variability in results across studies using random effect models. We used the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach to rate quality of evidence about estimates of effect on an outcome-by-outcome basis for all outcomes. We presented our results with a GRADE summary table.
RESULTS
Twenty-four trials including 8311 CKD patients proved eligible. The results left considerable uncertainty regarding the impact of cinacalcet on reducing fractures (relative risk [RR] 0.59, 95% confidence interval [CI] 0.13-2.60; heterogeneity: p = 0.03, I(2)= 78%; very low quality evidence), and indicated that cinacalcet did not reduce hospitalizations due to cardiovascular events (RR 0.93, 95% CI 0.85-1.02, moderate quality of evidence), cardiovascular mortality (RR 0.95, 95% CI 0.84-1.07; heterogeneity p= 0.61, high quality evidence) or all-cause mortality (RR 0.96, 95% CI 0.89-1.04; heterogeneity: p= 0.98, I(2)= 0%; moderate quality evidence). Cinacalcet reduced the need for parathyroidectomy (RR 0.30, 95% CI 0.22-0.42; heterogeneity: p= 0.70, I(2)= 0%; absolute effect 55 fewer per 1000 [95% CI 61 fewer to 45 fewer], high quality of evidence). The most common adverse event associated with cinacalcet therapy was gastrointestinal side effects. Cinacalcet increased nausea (RR 2.16, 95% CI 1.46-3.21, absolute effect 158 more per 1000 [95% CI 82 more to 302 more]) and vomiting (RR 2.15, 95% CI 1.66-2.80, absolute effect 63 more per 1000 [95% CI 109 more to 171 more]). Cinacalcet treatment increased the rate of hypocalcemia (RR 6.0, 95% CI 3.65-9.87; heterogeneity: p= 0.71, I(2)= 0%, absolute effect 20 more per 1000 [95% CI 11 more to 36 more], high quality of evidence).
CONCLUSIONS
In the hands of clinicians participating in these studies, cinacalcet decreased the rate of parathyroidectomy but had no influence on mortality. Patients and clinicians can trade of the benefit of fewer parathyroidectomies against the adverse effects.

Review
BACKGROUND
People who have chronic kidney disease (CKD) have important changes to bone structure, strength, and metabolism. Children experience bone deformity, pain, and delayed or impaired growth. Adults experience limb and vertebral fractures, avascular necrosis, and pain. The fracture risk after kidney transplantation is four times that of the general population and is related to Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) occurring with end-stage kidney failure, steroid-induced bone loss, and persistent hyperparathyroidism after transplantation. Fractures may reduce quality of life and lead to being unable to work or contribute to community roles and responsibilities. Earlier versions of this review have found low certainty evidence for effects of treatment. This is an update of a review first published in 2005 and updated in 2007.
OBJECTIVES
This review update evaluates the benefits and harms of interventions for preventing bone disease following kidney transplantation.
SEARCH METHODS
We searched the Cochrane Kidney and Transplant Register of Studies up to 16 May 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov.
SELECTION CRITERIA
RCTs and quasi-RCTs evaluating treatments for bone disease among kidney transplant recipients of any age were eligible.
DATA COLLECTION AND ANALYSIS
Two authors independently assessed trial risks of bias and extracted data. Statistical analyses were performed using random effects meta-analysis. The risk estimates were expressed as a risk ratio (RR) for dichotomous variables and mean difference (MD) for continuous outcomes together with the corresponding 95% confidence interval (CI). The primary efficacy outcome was bone fracture. The primary safety outcome was acute graft rejection. Secondary outcomes included death (all cause and cardiovascular), myocardial infarction, stroke, musculoskeletal disorders (e.g. skeletal deformity, bone pain), graft loss, nausea, hyper- or hypocalcaemia, kidney function, serum parathyroid hormone (PTH), and bone mineral density (BMD).
MAIN RESULTS
In this 2019 update, 65 studies (involving 3598 participants) were eligible; 45 studies contributed data to our meta-analyses (2698 participants). Treatments included bisphosphonates, vitamin D compounds, teriparatide, denosumab, cinacalcet, parathyroidectomy, and calcitonin. Median duration of follow-up was 12 months. Forty-three studies evaluated bone density or bone-related biomarkers, with more recent studies evaluating proteinuria and hyperparathyroidism. Bisphosphonate therapy was usually commenced in the perioperative transplantation period (within 3 weeks) and regardless of BMD. Risks of bias were generally high or unclear leading to lower certainty in the results. A single study reported outcomes among 60 children and adolescents. Studies were not designed to measure treatment effects on fracture, death or cardiovascular outcomes, or graft loss.Compared to placebo, bisphosphonate therapy administered over 12 months in transplant recipients may prevent fracture (RR 0.62, 95% CI 0.38 to 1.01; low certainty evidence) although the 95% CI included the possibility that bisphosphonate therapy might make little or no difference. Fracture events were principally vertebral fractures identified during routine radiographic surveillance. It was uncertain whether any other drug class decreased fracture (low or very low certainty evidence). It was uncertain whether interventions for bone disease in kidney transplantation reduce all-cause or cardiovascular death, myocardial infarction or stroke, or graft loss in very low certainty evidence. Bisphosphonate therapy may decrease acute graft rejection (RR 0.70, 95% CI 0.55 to 0.89; low certainty evidence), while it is uncertain whether any other treatment impacts graft rejection (very low certainty evidence). Bisphosphonate therapy may reduce bone pain (RR 0.20, 95% CI 0.04 to 0.93; very low certainty evidence), while it was very uncertain whether bisphosphonates prevent spinal deformity or avascular bone necrosis (very low certainty evidence). Bisphosphonates may increase to risk of hypocalcaemia (RR 5.59, 95% CI 1.00 to 31.06; low certainty evidence). It was uncertain whether vitamin D compounds had any effect on skeletal, cardiovascular, death, or transplant function outcomes (very low certainty or absence of evidence). Evidence for the benefits and harms of all other treatments was of very low certainty. Evidence for children and young adolescents was sparse.
AUTHORS' CONCLUSIONS
Bisphosphonate therapy may reduce fracture and bone pain after kidney transplantation, however low certainty in the evidence indicates it is possible that treatment may make little or no difference. It is uncertain whether bisphosphonate therapy or other bone treatments prevent other skeletal complications after kidney transplantation, including spinal deformity or avascular bone necrosis. The effects of bone treatment for children and adolescents after kidney transplantation are very uncertain.

OBJECTIVES/HYPOTHESIS
The primary objective of this study was to assess the safety of parathyroidectomy during pregnancy as treatment for hyperparathyroidism (HPTH) in comparison to nonsurgical management plans. Secondary outcomes involved analyzing the safety of surgery in the third trimester and the benefit of operating on asymptomatic pregnant patients.
STUDY DESIGN
Systematic review.
METHODS
PRISMA-guided systematic review of all cases of primary hyperparathyroidism during pregnancy published in peer-reviewed English journals on PubMed/MEDLINE, EMBASE, and SCOPUS from 1980 to 2020.
RESULTS
A total of 75 manuscripts were included in this review describing 382 cases of gestational hyperparathyroidism. The median maternal age was 31 years. Overall, 108 cases (28.3%) underwent parathyroidectomy during pregnancy while 274 cases (71.7%) were treated nonsurgically. The majority of surgeries took place during the second trimester (67.6%). Complications and/or deaths were less likely to occur after surgery in the second trimester (4.48%) as compared to surgery in the third trimester (21.1%). Nine surgically treated cases resulted in infant complications and/or death; however, none of these nine cases had any surgical complications. Despite these complications, the overall infant complication rate for patients who underwent surgical treatment remained lower than that of patients treated with conservative therapy (9.1% vs. 38.9%).
CONCLUSIONS
This review suggests that for all pregnant patients with diagnosed HPTH, parathyroidectomy should be considered regardless of symptomatology. Our data suggest that parathyroidectomy is associated with fewer risks than more conservative treatments and results in better fetal outcomes. Surgery during the third trimester is feasible and surgery should be considered in both symptomatic and asymptomatic patients. Laryngoscope, 131:1915-1921, 2021.

Meta-Analysis
Efficacy of parathyroidectomy compared with active surveillance in patients with mild asymptomatic primary hyperparathyroidism: a systematic review and meta-analysis of randomized-controlled studies.
OBJECTIVE
Parathyroidectomy (PTx) has an established benefit in patients with symptomatic primary hyperparathyroidism (PHPT). However, its efficacy in mild asymptomatic PHPT has not been proven. This study aimed to systematically review and meta-analyze the best available evidence from randomized-controlled trials comparing the efficacy of PTx over conservative management (non-PTx) on skeletal outcomes [fractures and bone mineral density (BMD)], nephrolithiasis risk and quality of life (QoL) in patients with mild asymptomatic PHPT.
METHODS
A comprehensive literature search was conducted in PubMed, Scopus and Cochrane databases, from conception to February 23, 2020. Data were extracted from the studies that fulfilled the eligibility criteria and were synthesized quantitatively (fixed or random effects model) as relative risks and percentage mean differences (MD) with 95% confidence intervals (CI). I index was employed for heterogeneity.
RESULTS
Four studies were included in the meta-analysis. There was no difference in fracture risk between PTx and active surveillance. The PTx group demonstrated higher BMD [MD 3.55% (95% CI 1.81, 5.29) in lumbar spine and 3.44% (95% CI 1.39, 5.49) in total hip, without difference in femoral neck and forearm] and lower calcium concentrations (MD - 13.26%, 95% CI - 7.10, - 19.43) compared with the non-PTx group. No difference was observed between groups regarding nephrolithiasis or QoL indices, except for general health (higher in PTx group).
CONCLUSIONS
In patients with mild asymptomatic PHPT, PTx increases BMD and reduces serum calcium concentrations. However, its superiority over active surveillance in terms of fracture risk, nephrolithiasis and QoL cannot be supported by current data.

Meta-Analysis Review
BACKGROUND
Focused exploration (FE) and bilateral parathyroid exploration (BE) are the standard surgical options for patients with primary hyperparathyroidism. However, the relative risk of recurrence, persistence, overall failure, reoperation, and any complications associated with either surgical approach is unclear. This study compared the outcomes and complication rates after FE and BE for patients with primary hyperparathyroidism.
METHODS
PubMed and Embase were searched for studies comparing these outcomes between FE and BE. A meta-analysis was performed using RevMan 5.3 software. Published data were pooled using the DerSimonian random-effect model, and results were presented as odds ratio (OR) or mean difference with 95% confidence interval (CI).
RESULTS
A total of 12,743 patients from 19 studies were included in this meta-analysis. In comparison with BE, the FE arm had comparable rates of recurrence (OR 1.08; 95% CI 0.59-2.00; p = 0.80; n = 9 studies), persistence (OR 0.89; 95% CI 0.58-1.35; p = 0.58; n = 13), overall failure (OR 0.88; 95% CI 0.58-1.34; p = 0.56; n = 13), and reoperation (OR 1.05; 95% CI 0.25-4.32; p = 0.95, n = 4). The operative time was significantly shorter (mean difference = -39.86; 95% CI -53.05 to -26.84; p < 0.01, n = 9), with a lower overall complication rate in the FE arm (OR 0.35; 95% CI 0.15-0.84; p = 0.02; n = 12). The latter was attributed predominantly to a lower risk of transient hypocalcemia (OR 0.36; 95% CI 0.14-0.90; p = 0.03; n = 9). There was a significant heterogeneity among these studies for all outcomes except for disease recurrence.
CONCLUSIONS
Compared with BE, FE has similar recurrence, persistence, and reoperation rates but significantly lower overall complication rates and shorter operative time.

Meta-Analysis
PURPOSE
Primary hyperparathyroidism (PHPT) is associated with increased risk of cardiovascular morbidity and mortality. We aim to determine whether parathyroidectomy (PTX) can change cardiometabolic risk factors including serum lipids, glycemic parameters, systolic and diastolic blood pressure, C reactive protein (CRP), and body mass index (BMI).
METHODS
MEDLINE, Web of Science, Scopus, and Google Scholar were searched for relevant articles published till June 2020. Fixed-effect or random-effects models were used to estimate the weighted mean difference (WMD) and 95% CI for outcomes where applicable.
RESULTS
In total, 34 studies were eligible to be included in the current meta-analysis. Our results indicated no favorable change in serum triglyceride (n = 13, WMD = -0.06, 95% CI: -0.15, 0.03 mmol/L), total cholesterol (n = 15, WMD = 0.01, 95% CI: -0.14, 0.16 mmol/L), LDL-C (n = 10, WMD = -0.01, 95% CI: -0.17, 0.19 mmol/L), HDL-C (n = 10, WMD = 0.03, 95% CI: -0.001, 0.06 mmol/L), and CRP (n = 5, WMD = 0.82, 95% CI: -0.01, 1.64 mg/L) after PTX in PHPT patients. However, glucose (n = 24, WMD = -0.16, 95% CI: -0.26, -0.06 mmol/L), serum insulin (n = 12, WMD = -1.11, 95% CI: -1.73, -0.49 µIU/mL), systolic (n = 17, WMD = -10.14, 95% CI: -12.27, -8.01 mmHg), and diastolic (n = 16, WMD = -5.21, 95% CI: -7.0, -3.43 mmHg) blood pressures were decreased after PTX, whilst a significant increase was observed in BMI (n = 13, WMD = 0.35, 95% CI: 0.19, 0.51 kg/m).
CONCLUSIONS
PTX could improve glycemic parameters and blood pressure, without any significant change in serum lipoproteins and CRP.

Meta-Analysis
BACKGROUND
Tertiary hyperparathyroidism occurs in 25% to 50% of kidney-transplanted patients. Indication of parathyroidectomy is now discussed, since the calcimimetic agent, cinacalcet, is an alternate option. The effects of either of these treatments on graft function remain controversial, studied only in small cohorts showing either decrease or absence of modification. We performed a meta-analysis to evaluate the evolution of graft function after surgical or medical treatment.
METHODS
Studies assessing graft function in tertiary hyperparathyroidism after parathyroidectomy or cinacalcet introduction were enrolled into quantitative analysis using Pubmed, Embase, and Cochrane databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis reporting guidelines. Among 68 screened studies, 18 had no missing data and were included for statistical analyses. We performed random effect meta-analysis to determine changes in serum creatinine and estimated glomerular filtration rate.
RESULTS
Seven studies assessing the evolution of graft function 6 and/or 12 months after parathyroidectomy and 13 after administration of cinacalcet were included. Meta-analysis found no significant variations after parathyroidectomy in serum creatinine (6 studies, 314 patients) and estimated glomerular filtration rate (2 studies, 105 patients). No significant variation was found after administration of cinacalcet in serum creatinine (10 studies, 404 patients) and estimated glomerular filtration rate (6 studies, 149 patients). A significant heterogeneity between the studies (P < .01, Cochran's Q) was found.
CONCLUSION
Meta-analysis shows that parathyroidectomy and cinacalcet do not significantly impair graft function in patients with tertiary hyperparathyroidism. However, the significant heterogeneity between selected studies, partially explained by the lack of consensual definition of tertiary hyperparathyroidism, limits the conclusions of all previously published series.

Review
BACKGROUND
There has been a substantial increase in incidence of thyroid cancer globally over the past three decades, emphasizing the necessity for efficient surgical management. Surgical intervention requires meticulous lymphatic dissection; however, it is challenging to both accurately identify lymph nodes and preserve the surrounding structures. We investigated the role of carbon nanoparticles in endoscopic thyroid cancer surgery to improve surgical effects and reduce postoperative complications.
METHODS
Chinese and English literature databases from inception to May 2023 were searched based on inclusion criteria, and data were extracted independently by two investigators. STATA software was used for data analysis.
RESULTS
A comprehensive systematic review and meta-analysis were conducted with 13 publications (9 randomized and 4 non-randomized controlled trials). The results demonstrated that the application of carbon nanoparticles in thyroid surgery led to an increase in the number of retrieved lymph nodes and identification of metastatic lymph nodes. Furthermore, it considerably reduced the rate of improper parathyroidectomy and the incidence of postoperative hypocalcemia.
CONCLUSION
The application of carbon nanoparticles can effectively improve the effects of surgical treatment, can enhance the identification of intraoperative lymph nodes, reduce postoperative complications, and protect the integrity and function of the parathyroid gland.
