Meta-Analysis
OBJECTIVES
While obstructive sleep apnea (OSA) is associated with several chronic health conditions such as hypertension, obesity, and chronic hypoxia, there is limited information on its association with neuromuscular and spinal pathologies that may be of interest to a musculoskeletal (MSK) medicine or pain management clinician. The objective of this study was to perform a systematic literature review to examine the association between OSA and cervical spine pathologies, postural changes, and pain.
DESIGN
We systematically reviewed PubMed and Embase databases up to 4/15/2019. We included studies that explored associations between OSA and a) pain, b) postural characteristics or changes, or c) cervical spine morphology. Systematic reviews, meta-analysis, randomized control trials, cohort studies, and case-control studies were included. Case reports, narrative reviews or expert opinion papers were excluded. From the articles that met selection criteria, information regarding type, direction and magnitude of such associations was extracted. The OSA-pain association studies were further divided into 3 subgroups: neuropathic, temporomandibular, and chronic pain.
RESULTS
21 articles that met our study criteria were selected for this review. Two studies were on cervical spine pathologies, eight on postural changes, and eleven on pain associated with OSA. Exploring the association between OSA and cervical spine pathologies, postural changes, and pain in this systematic review we found: (1) Cervical spine lesions, fusions, and abnormalities that reduce retropharyngeal space are associated with OSA, likely by way of worsening posture and decreasing range of motion. (2) Head extension and anteriorization are associated with OSA likely as a compensatory mechanism. Extension may improve airway function, while anteriorization helps to maintain visual sense. (3) Head-of-bed-elevation may improve OSA symptoms and can possibly supplement other conservative treatment measures. (4) Neuropathic pain is associated with OSA, likely by way of inflammatory pathways. (5) Oral appliance use (eg mandibular advancement/protruding device) in OSA likely contributes to transient temporomandibular pain. (6) There is little association between OSA and chronic pain prevalence. (7) Increased pain intensity and decreased pain tolerance are somewhat associated with OSA, likely by way of hypoxemia and sleep fragmentation.
CONCLUSIONS
Clinicians in MSK and pain medicine need to consider these associations and consider obtaining imaging studies and/or making referrals for management of their OSA to better provide appropriate care to these patients.

Meta-Analysis
BACKGROUND
Percutaneous coronary intervention (PCI) on severely calcified coronary lesions is challenging. Coronary calcified nodule (CN) refers to an eccentric and protruding coronary calcification associated with plaque vulnerability and adverse clinical events. This study aims to conduct an extensive review of CNs, focusing on its prognostic impact in comparison with nonnodular coronary calcification (N-CN).
METHOD
A systematic literature review on PubMed, MEDLINE, and EMBASE databases was conducted for relevant articles. Observational studies or randomized controlled trials comparing CNs and N-CNs were included.
RESULTS
Five studies comparing CNs and N-CNs were pertinent for inclusion. The total number of individuals across these studies was 1456. There were no significant differences in the baseline demographic, clinical, and angiographic data between the CN and N-CN groups. Intracoronary imaging was always utilized. At follow-up, CNs were associated with significantly increased, target vessel revascularization [odds ratio (OR) 2.16; 95% confidence interval (CI): 1.39-3.36, P-value < 0.01, I2 = 0%] and stent thrombosis (OR 9.29; 95% CI: 1.67-51.79, P-value = 0.01, I2 = 0%) compared with N-CN. A trend for greater cardiac death was also assessed in the CN group (OR 1.75; 95% CI: 0.98-3.13, P-value = 0.06, I2 = 0%).
CONCLUSION
CN has a significantly negative impact on outcomes when compared with N-CN.

BACKGROUND
Although adhesive strapping (AS) for pediatric umbilical hernia (UH), which was once obsolete, has been reconsidered as a common practice in Japan, its efficacy is still unclear. This study aimed to evaluate its efficacy by reviewing related articles.
METHODS
A comprehensive literature search of PubMed, Cochrane, Google Scholar, and Igaku Chuo Zasshi via Ichushi-Web was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Cohort studies reporting on the UH closure rate after AS compared with observation-only management were included.
RESULTS
A total of 10 cohort studies were included, and the overall UH closure rate was not statistically significant (p=0.31, risk ratio (RR)=0.76, 95% confidence interval (CI) 0.45 to 1.28). However, there were significant differences in the UH closure rate at the age of 6 months (p<0.01, RR=0.55, 95% CI 0.41 to 0.75) and the efficacy of preventing protruding umbilici with redundant skin (p=0.049, RR=0.16, 95% CI 0.03 to 0.99).
CONCLUSIONS
Although the efficacy of AS on UH compared with observation-only management did not differ in terms of the UH closure rate, the application of AS may be effective for faster UH closure and the prevention of protruding umbilici. However, due to the high heterogeneity of the study, further large-scale studies, particularly randomized controlled trials, are warranted to reach a conclusion.

Review
BACKGROUND
Coral reef aorta (CRA) is defined by the presence of heavily calcified exophytic plaques that protrude into the aortic lumen. However, the exact causes and development of this condition are still not fully understood. When the aortic branches are affected, it can result in various symptoms. Despite ongoing research, there is currently no established consensus on the best treatment for CRA. This review aims to examine the latest findings regarding the clinical presentation and approach to treating patients with CRA.
METHODS
We conducted a systematic electronic search of the literature using the PubMed and Embase databases. Throughout the search, we adhered to the guidelines outlined in the PRISMA framework. From the identified publications, we extracted information pertaining to patients' characteristics, symptoms, and types of treatment from a total of 124 cases reported over the past 20 years. The primary focus of our analysis was to assess the improvement of signs and symptoms, as well as to evaluate any postoperative complications. To achieve this, we performed both descriptive and inferential analyses on the collected data. Additionally, we conducted subgroup analyses based on treatment types and symptoms observed at presentation, presenting the findings in the form of odds ratios (ORs).
RESULTS
After removing duplicate articles, we carefully screened the titles of 67 retrieved articles and excluded those that did not align with the purpose of our study. Subsequently, we thoroughly analyzed the remaining 41 articles along with their references, ultimately including 29 studies that were deemed most relevant for our systematic review. We examined a total of 124 cases of patients diagnosed with CRA, comprising 77 (62.1%) females and 48 (38.7%) males, with a mean age of 59 years (range: 37-84). The predominant signs and symptoms observed were intermittent claudication, reported in 57 (46.0%) patients, followed by refractory hypertension in 45 (36.3%) patients, intestinal angina in 28 (22.6%) patients, and renal insufficiency in 15 (12.1%) patients. Among the treated patients, 110 (88.7%) underwent open surgery repair (OSR), 11 (8.9%) received endovascular treatment, and 3 (2.4%) underwent laparoscopy. Postoperatively, a significant number of patients experienced substantial relief or complete resolution of their symptoms, as well as improved control of hypertension and renal function. In the group of patients treated with OSR, the inhospital stay mortality rate was 10.9%, the morbidity rate was 28.2%, and the reintervention rate was 15.5%. The high mortality rate during hospital stays in this group may be associated with such invasive procedures performed on patients who have substantial cardiovascular burden and multiple comorbidities. Conversely, no postoperative complications were reported in the group of patients treated with endovascular procedures or laparoscopic surgery.
CONCLUSIONS
While coral reef aorta (CRA) is considered a rare condition, it is crucial for the medical community to remain vigilant about its diagnosis, particularly in patients presenting with symptoms such as intermittent claudication, refractory hypertension, renal impairment, or intestinal angina. Based on the findings of this review, both OSR and endovascular treatment have shown promise as viable therapeutic options. Although endovascular therapies may not always be feasible or may have reduced durability in these calcified bulky lesions, they should be considered in patients with multiple comorbidities, due to the high postoperative mortality rates associated with more invasive approaches. Additionally, these endoluminal procedures have demonstrated good patency rates during the 18-month follow-up period. It is essential to emphasize that the treatment strategy should be determined on a case-by-case basis, involving a multidisciplinary team to tailor it to the specific needs of each individual patient.

Meta-Analysis
BACKGROUND
Facial attractiveness has social, psychological, and economic repercussions. Class II malocclusions are associated with a retroposition of the mandible, facial convexity, protruded upper lip, retruded lower lip, and pronounced mentolabial fold. Functional appliances (FA) try to increase mandibular length and normalize lip position, thereby decreasing the facial profile convexity and aesthetics.
OBJECTIVES
The aim of this review and meta-analysis is to investigate the effects of FA on the soft tissues in a non-cephalometric two-dimensional manner.
SEARCH METHODS
Medline (via PubMed), Embase (via Ovid), Web of Science, and Cochrane Central were used to identify studies describing the soft tissue results of FA in a non-cephalometric way. The search was conducted up to July 2021.
SELECTION CRITERIA
Prospective and retrospective studies investigating the effects of FA appliances on the soft tissues, with non-ionizing, two-dimensional imaging, including an attractiveness assessment based on Visual Analogue Scale or Likert scale, were considered eligible.
DATA COLLECTION AND ANALYSIS
Data extraction was performed separately by two authors. Risk of bias was assessed using the ROBINS-I tool.
RESULTS
From the eight eligible studies, four were included in the meta-analysis to investigate the influence of assessors on facial attractiveness scores. Age range of the included studies varied from 8 to 21 years old including 313 Caucasian patients whereof 64% females. Six out of eight studies used growing patients as treatment group and only two studies reported follow-up after the end of treatment. Overall facial attractiveness increased after treatment with FA, resulting from a decrease in facial convexity and a normalization of the lip relationship. Orthodontists score higher aesthetic improvements after FA treatment as compared to laypeople.
CONCLUSIONS
Current evidence suggests the positive effects of FA on the facial attractiveness in growing and non-growing patients. FA normalize the lip relationship. Furthermore, they tend to decrease facial convexity and advance the chin point. More pleasing results can be expected in growing patients. Orthodontists are more generous when assessing treatment changes as compared to laypeople.

Hydrogels are extraordinarily versatile by design and can enhance repair in diseased and injured musculoskeletal tissues. Biological fixation of these constructs is a significant determinant factor that is critical to the clinical success and functionality of regenerative technologies for musculoskeletal repair. In the context of an intervertebral disc (IVD) herniation, nucleus pulposus tissue protrudes through the ruptured annulus fibrosus (AF), consequentially impinging on spinal nerve roots and causing debilitating pain. Discectomy is the surgical standard of care to treat symptomatic herniation; however these procedures do not repair AF defects, and these lesions are a significant risk factor for recurrent herniation. Advances in tissue engineering utilize adhesive hydrogels as AF sealants; however these repair strategies have yet to progress beyond preclinical animal models because these biomaterials are often plagued by poor integration with AF tissue and lead to large variability in repair outcomes. These critical barriers to translation motivate this article to review the material composition of hydrogels that have been evaluated for AF repair, proposed mechanisms of how these biomaterials interface with AF tissue, and their functional outcomes after treatment in order to inform the development of new hydrogels for AF repair. In this systematic review, we identify 18 hydrogel formulations evaluated for AF repair, all of which demonstrate large heterogeneity in their interfacing mechanisms and reported outcome measures to assess the effectiveness of repair. Hydrogels that covalently bond to AF tissue were found to be the most successful in improving IVD biomechanical properties from the injured state, but none were able to restore properties to the intact state suggesting that new repair strategies with innovative surface chemistries are an important future direction. We additionally review biomechanical evaluation methods and recommend standardization in the field of AF tissue engineering to establish mechanical benchmarks for translation and ensure clinical feasibility.

Meta-Analysis
Midface hypoplasia (MFH) is a long-term sequela of cleft lip and palate repair, and is poorly understood. No study has examined the aggregate data on sagittal growth restriction of the midface following repair of the lip, but not palate, in these patients. A systematic review of 3780 articles was performed. Twenty-four studies met inclusion criteria and 11 reported cephalometric measurements amenable to meta-analysis. Patients with Veau class I-III palatal clefts were included so long as they had undergone only lip repair. Groups were compared against both noncleft and unrepaired controls. Cephalometrics were reported for 326 patients (31.3% female). Noncleft controls had an average SNA angle of 81.25° ± 3.12°. The only patients demonstrating hypoplastic SNA angles were those with unilateral CLP with isolated lip repair (77.4° ± 4.22°). Patients with repaired CL had SNA angles similar to noncleft controls (81.4° ± 4.02°). Patients with unrepaired CLP and CL tended toward more protruding maxillae, with SNA angles of 83.3° ± 4.04° and 87.9° ± 3.11°, respectively. Notably, when comparing SNA angles between groups, patients with CLP with isolated lip repair had significantly more hypoplastic angles compared to those with repaired CL ( < .0001). Patients with CLP with isolated lip repair were also more hypoplastic than noncleft controls ( < .0001). In contrast, there was no significant difference between the SNA of patients with repaired CL and controls ( = .648). We found that cleft lip repair only appeared to contribute to MFH in the setting of concurrent cleft palate pathology, suggesting that scarring from lip repair itself is unlikely to be the predominant driver of MFH development. However, studies generally suffered from inadequate reporting of timing, technique, follow-up time, and cleft severity.

Flexor tendon rupture after volar plate fixation of distal radius fracture (DRF) is rare. There is no consensus as to how to prevent them. The aim of our study was to identify the pathological mechanisms, and to establish the clinical and epidemiological profile of patients suffering from this complication. We carried out a systematic review using the PubMed, Scopus and Cochrane databases. Studies were included if they described complete or partial flexor tendon rupture following volar plate fixation of DRF. Forty-six 46 were included, for a total of 145 patients were reported: 138 from the literature, and 7 from our personal experience. Etiology was usually mechanical, by impingement with either the plate or protruding screws. Plate impingement was due to positioning beyond the watershed line, consolidation with posterior tilt, plate thickness, or low palmar cortical angle. Mean patient age was 62.4 years (range, 23-89 years). Median postoperative interval was 8 months (range, 3-120 months). Flexor pollicis longus was the most frequently injured tendon. The plate should be positioned proximally to the watershed line if possible, to ensure good initial reduction. Hardware should be removed 4 months after surgery if the plate is causing impingement according to the Soong criteria or if signs of tenosynovitis appear.
