Could Osteopontin be a useful biomarker in the diagnosis and severity assessment of osteoarthritis? A systematic review and meta-analysis of recent evidence.

PURPOSE: Osteoarthritis (OA) patients demonstrated higher Osteopontin (OPN) plasma, serum, and synovial fluid concentrations than healthy individuals. In the present study, we aimed to investigate whether OPN could be used as a diagnostic or prognostic marker for OA symptom/disease severity. METHODS: Using Web of Science, PubMed, Scopus, and Embase, we conducted a systematic review and meta-analysis of studies that measured OPN levels in OA patients' plasma, serum, or synovial fluid. After setting the eligibility criteria, data extraction, and quality assessment of the identified studies, we performed statistical analysis using Revman 5.4 and Open Meta analyst. RESULTS: OPN has been found to be associated with advanced knee joint damage in OA patients. In addition, higher expression of OPN is thought to be associated with disease progression. Nevertheless, further studies should examine the role of other markers of chronic bone damage, such as leptin and sclerostin. This systematic review and meta-analysis included 14 studies with a total of 776 cases and 530 controls. OPN was significantly elevated in osteoarthritis patients' plasma, serum, and synovial fluid samples, with significant heterogeneity between studies. CONCLUSION: We recommend that OPN plasma and synovial fluid levels be measured as a diagnostic and prognostic marker to determine the severity of OA symptoms.

Sonographic reference values of cranial nerve size: A systematic review and meta-analysis.

INTRODUCTION/AIMS: Ultrasonography of the cranial nerves has recently gained attention for assessment of inflammatory, compressive, or degenerative neuropathies. However, sonographic reference values of cranial nerves have received less attention than those of peripheral nerves. In this systematic review and meta-analysis we aimed to provide current evidence of sonographic reference values for cranial nerve size. METHODS: By searching Medline (via PubMed), Scopus, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science, we conducted a systematic review and meta-analysis of studies that reported ultrasound measurements of the facial, spinal accessory, and hypoglossal nerves in healthy adults. We included studies that reported either the sonographic cross-sectional area (CSA) or the nerve diameter; the included nerves were subgrouped according to the site of nerve measurement. RESULTS: Fourteen studies with a total of 661 participants and 1437 ultrasound nerve measurements met the inclusion criteria. The anatomical sites for each nerve were combined to provide single-nerve mean measurements. We found an overall mean nerve diameter of 0.80 mm for the facial nerve, 0.63 mm for the spinal accessory nerve, and 1.82 mm2 for hypoglossal nerve CSA. DISCUSSION: This meta-analysis provides reference values for the diameter and cross-sectional area of the facial, spinal accessory, and hypoglossal nerves at different sites, which can be used as guidance in clinical practice to detect pathological changes in cranial nerve size in cranial neuropathies. We recommend further validation in large-scale studies as well as standardization of the scanning protocols.

The Outcomes of Modified Millard Technique Versus Tennison-Randall Technique in Unilateral Cleft Lip Repair: A Comparative Trial.

BACKGROUND: This study aimed to use anthropometric measurements taken pre- and post-operation to evaluate quantitative assessment of modified Millard technique compared with Tennison-Randall technique in unilateral cleft lip (UCL) repair. MATERIALS AND METHODS: Prospective randomised controlled study recruited infants scheduled for UCL repair. Infants aged 2-6 months, either complete or incomplete deformity. A total of 68 patients were randomised in 1:1 ratio to undergo either modified Millard technique (Group I) or Tennison-Randall technique (Group II). RESULTS: Group I had significantly longer operative time than Group II (85.7 ± 7.4 vs. 68.7 ± 8.8 min, respectively; P < 0.001). Group I has less post-operative wound infection, wound dehiscence and wound scarring than Group II, but Group II has less post-operative lip notch. In Group I, greater increases in post-operative horizontal lip length and vertical lip height were observed, compared to Group II, without statistically significant difference. Group I showed a greater reduction in nasal width and total nasal width than Group II, without statistically significance. Group II had a greater increase in philtral height. However, only post-operative Cupid's-bow width was significantly different between two groups (P = 0.041). CONCLUSION: Overall results demonstrate no significant differences between modified Millard technique and Tennison-Randall technique.

Causes of Death in Nonmalignant Meningioma.

OBJECTIVES: Nonmalignant meningioma (NM) is the most common brain tumor in the United States (U.S.), accounting for 54% of nonmalignant brain tumors. This study aims to investigate the causes of death in NM patients and their possible associations with demographic factors. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database, we analyzed 116,430 NM patients diagnosed between the years 2004 and 2018. RESULTS: A total of 31,640 deaths were observed. Non-tumor diseases accounted for 63.9% of all deaths. Out of these non-tumor deaths, we found that the most common causes were heart disease (18.7% of deaths), cerebrovascular disease (7.4% of deaths), and Alzheimer disease (4.5% of deaths). On the other hand, cancer was responsible for 27.4% of deaths, while in situ and benign tumor deaths accounted for only 8.7%. CONCLUSIONS: This is the first U.S. population-based study to investigate the causes of death in NM patients. We found that non-tumor diseases accounted for the majority of deaths. The risks of mortality caused by heart disease, cerebrovascular disease, diabetes, and Alzheimer disease were significantly elevated. These data can help improve survival outcomes for NM patients, particularly if adjusted by demographic risk factors.

The role of creatine kinase in distinguishing generalized tonic-clonic seizures from psychogenic non-epileptic seizures (PNES) and syncope: a retrospective study and meta-analysis of 1300 patients.

BACKGROUND/AIM: As the clinical differentiation between epileptic seizures, psychogenic non-epileptic seizures (PNES), and syncope depends mainly on a detailed report of the event, which may not be available, an objective assessment of a potential biochemical analysis is needed. We aimed to investigate whether serum creatine kinase (CK) could be used to differentiate epileptic seizure from PNES and syncope and to assess the strength of evidence present. METHODS: We directed a retrospective cohort study coupled with a systematic review and meta-analysis of studies that measured CK in patients with epilepsy, PNES, syncope, and healthy controls. RESULTS: The cohort study, which traced 202 patients, showed that the CK level was significantly higher 48 h after the event in the epilepsy group versus patients with syncope (p < 0.01) Along with 1086 patients obtained through a database search for meta-analysis, CK level compared to different types of seizures from PNES was higher in epileptic seizure patients with a mean difference of 568.966 mIU/ml (95% CI 166.864, 971.067). The subgroup analysis of CK showed that it was higher in GTCS compared to syncope with a mean difference of 125.39 mIU/ml (95% CI 45.25, 205.52). DISCUSSION: Increased serum levels of CK have been associated mainly with epileptic seizures in relation to non-epileptic events. However, further studies would try to explore the variation in measurements and any other potential diagnostic marker. CONCLUSION: The cohort study shows that the CK level in epilepsy seizures is higher after 48 h from the event compared to syncope. Moreover, the meta-analysis results show the present diagnostic utility of CK and its importance to be used in accordance with a detailed report of the event.
