This systematic review evaluated the effectiveness of bone marrow aspirate (BMA) to enhance bone repair in humans. Comprehensive survey of ramdomized clinical trials published up to June 2021 and listed in PubMed/MEDLINE, EMBASE, and Cochrane Library databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Two reviewers independently searched eligible studies, made a final article selection, and extracted the data of the selected studies to evaluate it qualitatively. Overall, 13 studies were included in the review. Experimental models involved Posttraumatical aseptic nonunions of long bones of the upper limb, alveolar ridges following tooth extraction, atrophic mandibular fracture, benign bone lesions, bilateral tibial lengthening, fracture of intracapsular neck femur, maxillary horizontal ridge augmentation, non-traumatic femoral head necrosis, and sinus maxillary augmentation. The analyses included radiography, tomography, biopsies, and clinical evaluations. Ten studies reported enahanced bone formation (primary outcome) with combined use or not of BMA with other biomaterials and three studies found no benefit resulting from the use of BMA to treat bony defects. Secundary outcomes related to the healing process were also evaluated and positive, such as postoperative complications and pain visual analogue score. Within the limits of the present study, it can be concluded that BMA can improve the early stages of bone healing process.

Background: Knee osteoarthritis is the most common musculoskeletal progressive disorder that affects nearly 303 million people worldwide. This condition prevails in 10% males and 13% females among the elders above 60. Although there is conventional nonsurgical and surgical treatment available for knee osteoarthritis, there is a fascinating interest in bone marrow aspirate concentrate (BMAC) as well as adipose-derived mesenchymal stem cells (AD-MSC), including enzymatically treated stromal vascular fraction (SVF) and mechanically treated (microfat/nanofat) injections among physicians. Hence, this systematic review aims to determine the efficacy of BMAC and AD-MSCs (enzyme and mechanically treated) injections for knee osteoarthritis treatment. Methods: A systematic review was performed on the following data sources (PubMed, Scopus, Google Scholar, EMBASE, and Cochrane Library) published on March 31, 2021. The keywords or MeSH terms include 'Knee Osteoarthritis with 'Bone marrow aspirate concentrate' OR 'BMAC' or with 'Adipose-derived mesenchymal stem cells (AD-MSC)' or with 'Stromal vascular fraction' OR 'SVF' or 'Mechanically treated AD-MSC (mfat/nanofat)'. In addition, the retrieved articles were further reviewed to identify relevant research studies. Results: The authors reviewed and tabulated data based on the year of study, study type, therapy protocol, patient population, outcome measures, and interpretation. Among the 382 records screened, 43 studies (16 on BMAC and 27 on AD-MSCs) were included in the systematic review study. Among them, only 5 were randomized controlled trials. These selected studies demonstrated short-term positive outcomes such as improvement in knee pain and function with no adverse side effects. Moreover, researchers reported varied administration methods of BMAC or AD-MSC either as standalone or in combination with other conservative procedures such as PRP (Platelets Rich Plasma), HA (Hyaluronic acid), or surgery. Conclusions: BMAC and AD-MSC (enzymatically and mechanically treated) injections prove safer and more efficacious in patients with knee osteoarthritis for a shorter duration of 2 years. However, the available literature lacks high-quality studies with no varied clinical settings and long-term follow-up of more than two years.

Background: Bone marrow aspirate concentrate (BMAC) has emerged as a therapeutic option for symptomatic knee osteoarthritis (OA). Purpose: To systematically review the literature to evaluate the efficacy of isolated BMAC injection in the treatment of OA of the knee joint. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed by searching the PubMed, Embase, and Cochrane Library databases up to July 2020 to identify human studies that assessed the clinical outcomes of isolated BMAC injection for the treatment of knee OA. The electronic search strategy used was “bone marrow aspirate concentrate knee osteoarthritis.” Results: Eight studies met the inclusion criteria, including a total of 299 knees with a mean follow-up of 12.9 months (range, 6-30 months). Of all patient-reported outcomes assessed across studies, 34 of 36 (94.4%) demonstrated significant improvement from baseline to latest follow-up ( P < .05). Five studies evaluating numerical pain scores (visual analog scale and Numeric Rating Scale) reported significant improvements in pain level at final follow-up ( P < .01). However, 3 comparative studies evaluating BMAC in relation to other therapeutic injections failed to demonstrate the clinical superiority of BMAC. Conclusion: The BMAC injection is effective in improving pain and patient-reported outcomes in patients with knee OA at short- to midterm follow-up. Nevertheless, BMAC has not demonstrated clinical superiority in relation to other biologic therapies commonly used in the treatment of OA, including platelet-rich plasma and microfragmented adipose tissue, or in relation to placebo. The high cost of the BMAC injection in comparison with other biologic and nonoperative treatment modalities may limit its utility despite demonstrable clinical benefit.

Background: Ultrapurified alginate (UPAL) gel implantation has been demonstrated as effective in cartilage repair for osteochondral defects; however, cell transplantation within UPAL gels would be required to treat larger defects. Hypothesis: The combination of UPAL gel and bone marrow aspirate concentrate (BMAC) would enhance cartilage repair and subchondral bone repair for large osteochondral defects. Study Design: Controlled laboratory study. Methods: A total of 104 osteochondral defects (1 defect per knee) of 52 rabbits were randomly divided into 4 groups (26 defects per group): defects without any treatment (Defect group), defects treated using UPAL gel alone (UPAL group), defects treated using UPAL gel containing allogenic bone marrow mesenchymal stromal cells (UPAL-MSC group), and defects treated using UPAL gel containing BMAC (UPAL-BMAC group). At 4 and 16 weeks postoperatively, macroscopic and histologic evaluations and measurements of repaired subchondral bone volumes of reparative tissues were performed. Collagen orientation and mechanical properties of the reparative tissue were assessed at 16 weeks. Results: The defects in the UPAL-BMAC group were repaired with hyaline-like cartilage with well-organized collagen structures. The histologic scores at 4 weeks were significantly higher in the UPAL-BMAC group (16.9 ± 2.0) than in the Defect group (4.7 ± 1.9; P < .05), the UPAL group (10.0 ± 3.3; P < .05), and the UPAL-MSC group (12.2 ± 2.9; P < .05). At 16 weeks, the score in the UPAL-BMAC group (24.4 ± 1.7) was significantly higher than those in the Defect group (9.0 ± 3.7; P < .05), the UPAL group (14.2 ± 3.9; P < .05), and the UPAL-MSC group (16.3 ± 3.6; P < .05). At 4 and 16 weeks, the macroscopic evaluations were significantly superior in the UPAL-BMAC group compared with the other groups, and the values of repaired subchondral bone volumes in the UPAL-BMAC group were significantly higher than those in the Defect and UPAL groups. The mechanical properties of the reparative tissues were significantly better in the UPAL-BMAC group than in the other groups. Conclusion: The implantation of UPAL gel containing BMAC-enhanced hyaline-like cartilage repair and subchondral bone repair of osteochondral defects in a rabbit knee model. Clinical Relevance: These data support the potential clinical application of 1-step treatment for large osteochondral defects using biomaterial implantation with cell transplantation.

Background: Earthworm, also called dilong (Chinese language), has been used as a traditional Chinese medicine for thousands of years. Recently, some scientists believe that earthworm extracts (EE) can promote wound healing. However, its effectiveness remains controversial. We conducted a meta-analysis to evaluate the effect of EE on wound healing based on the healing rate.Methods: We comprehensively reviewed literature that mentioned EE for wound healing in the PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), VIP database for Chinese Technical Periodicals, and WanFang database that have been published until January 2021. We computed weighted mean difference (WMD) for analysis with RevMan 5.3 software in animal and human models groups. Two researchers independently selected studies and evaluated the risk of bias with the Cochrane Collaboration tool. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO (CRD42020168400).Results: From 2,486 articles, we selected 16 studies for analysis. EE treatment was associated with improvements in wound healing performance based on wound healing rate (mouse model: weighted mean difference (WMD) = 3.55, 95% confidence interval (CI): 2.34–4.77, p &lt; 0.00001; rat model: WMD = 17.29, 95% CI: 5.75–28.82, p = 0.003; rabbit model: WMD = 19.29, 95% CI: 9.95–28.64, p &lt; 0.0001). Clinical studies also confirmed that EE could reduce healing time in hospital (WMD = −8.94, 95% CI: −17.75 to −0.14, p = 0.05).Conclusion: The results of this meta-analysis demonstrated the efficacy of EE on wound healing process. As a corollary, EE can be a useful natural product for wound healing drug development.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=168400, identifier CRD42020168400.

Abstract   Oesophagectomy is associated with high morbidity. One of the postoperative complication observed after esophageal resection is Post Operative Delirium (POD), a psychiatric disease caused by major surgical stress and pharmacological treatments. POD can jeopardize patient healing-process since patients are not collaborative to perioperative care but also because they can harm themselves. Thus the aim of this systematic review was to identify POD factors and its effective management in patients undergone oesophagectomy for oesophageal/oesophagogastric-junction cancer. Methods A comprehensive systematic literature search was conducted using PubMed, Cochrane Library, Scopus, psycINFO and psycARTICLES in order to identify all articles published until January 2020. The following combinations of terms were used for the search strategy: neoplasm; esophagus; gastro-esophageal junction; oesophagectomy; delirium. The following inclusion criteria were set: full article published in English; patients with esophageal cancer undergone oesophagectomy; POD observed. Two researchers independently selected studies matching the inclusion criteria. Duplicate studies, non-relevant topic, data from abstracts or unpublished were excluded. Any disagreements between the researchers’ evaluation concerning inclusion of studies were resolved by consensus. Results Of 235 studies yielded by systematic literature search, 21 met inclusion criteria. POD incidence was observed between 3 and 38% of patients and was precursor of other complications in 1/3 of POD patients. Preoperative risk factors were older age, cerebrovascular disease and pulmonary disfunction. Anxiety and depression resulted predisposing factors. Perioperative risk factors were duration of surgery, ICU length of stay, colloids infusion and blood transfusion. Open-surgery seemed to influence POD more than minimally-invasive and robotic surgery. Interventions identified to treat POD were pharmacological (prophylactic haloperidol, insomnia treatment) and behavioral (patient reorientation by family involvement, bright-light therapy, early mobilization). Conclusion This systematic review identified preoperative, intraoperative and postoperative risk factors of POD after oesophagectomy. No standardized prevention nor treatment of POD was identified. POD impacts patients’ ability in perceiving postoperative symptoms. The difficulty in communicating with health professionals may lead to delay the diagnosis of others complications and prolong hospital stay. Therefore further trials are required to assess efficacy of different POD treatments aimed to enhance postoperative management.

Background: The formation of senile plaques and neurofibrillary tangles of the tau protein are the main pathological mechanism of Alzheimer’s disease (AD). Current therapies for AD offer discrete benefits to the clinical symptoms and do not prevent the continuing degeneration of neuronal cells. Therefore, novel therapeutic strategies have long been investigated, where curcumin (Curcuma longa) has shown some properties that can prevent the deleterious processes involved in neurodegenerative diseases. Objective: The aim of the present work is to review studies that addressed the effects of curcumin in experimental models (in vivo and in vitro) for AD. Method: This study is a systematic review conducted between January and June 2017, in which a consultation of scientific articles from indexed periodicals was carried out in Science Direct, United States National Library of Medicine (PubMed), Cochrane Library and Scielo databases, using the following descriptors: “Curcuma longa”, “Curcumin” and “Alzheimer’s disease”. Results: A total of 32 studies were analyzed, which indicated that curcumin supplementation reverses neurotoxic and behavioral damages in both in vivo and in vitro models of AD. Conclusion: The administration of curcumin in experimental models seems to be a promising approach in AD, even though it is suggested that additional studies must be conducted using distinct doses and through other routes of administration.

Background: Neural cells undergo functional or sensory loss due to neurological disorders. In addition to environmental or genetic factors, oxidative stress is a major contributor to neurodegeneration. In this context, there has been a growing interest in investigating the effects of essential oils (EOs) in recent years, especially in the treatment of neuropathologies. The chemical and biological effects of EOs have led to important treatment tools for the management of various neurological disorders. Objective: In the present study we performed a systematic review that sought to comprehend the neuroprotective effects of different EOs. Method: This work is a systematic review where an electronic search was performed on PubMed, Science direct, Cochrane Library and SciELO (Scientific Electronic Library Online) databases, covering the last 10 years, using “Essential oil” and “Neuroprotective effect” as reference terms. Results: A total of 9 articles were identified, in which the efficacy of EOs was described in experimental models of anxiety, dementia, oxidative stress, cerebral ischemia, Alzheimer’s disease and oxidative toxicity. Conclusion: EOs from different species of medicinal plants have shown positive responses in neurological disorders such as anxiety, dementia, oxidative stress, cerebral ischemia and oxidative toxicity. Thus, EOs emerges with the potential to be used as alternative agents in the treatment of neurological disorders.
