Aneurysmal bone cysts are vascular benign fibroblastic lesions usually found in bone that are locally destructive, with a greater incidence in the first and second decades of life. Patients usually undergo curettage or, less frequently, surgical resection, which may lead to growth disturbances and deformities in cases of large or complex lesions. Minimally invasive techniques such as sclerotherapy and endovascular embolization have been developed as an alternative or complement to surgery, with promising results. The authors present a rare case of an extraskeletal aneurysmal bone cyst successfully treated with minimally invasive techniques followed by surgical resection and provide a literature review of the current treatment options.

OBJECTIVE: To conduct a systematic review and meta-analysis to assess the effectiveness of ozone therapy in oral ulcers healing when compared to placebo or active treatments.
METHODS: The search was carried out using PubMed, EMBASE, Scopus, and Lilacs databases. Clinical trials involving human participants were included. The Risk Ratio (RR) and the standardized mean difference (SMD) with 95%CI (confidence interval) were calculated. The ROBINS-I (risk of bias in non-randomized studies of interventions) and RoB2 (risk of bias tool for randomized trials) assessment tool was used to detect bias.
RESULTS: After the selection process, 12 studies were included. The meta-analysis showed that ozone therapy helps to reduce the size of the traumatic and autoimmune ulcers (RR=-0.44; 95% CI -0.71,-0.17; I2=0%) in comparison to placebo. Regarding pain reduction, ozone was superior to placebo (RR = 1.29, 95% CI -1.6 to -0.95); I2=0%), and equivalent to topical corticosteroid and laser photobiomodulation (RR = 0.26, 95% CI -0.27,0.78, p = 0.34).
CONCLUSIONS: Ozone therapy is an alternative for accelerating healing and reducing pain for both traumatic and autoimmune ulcers. However, the quality of evidence is limited.
CONCLUSIONS: Oral ulcerations are usually painful and impact quality of life requiring different approaches to boost wound healing and reduce symptoms. For this purpose, ozone therapy is a promising strategy.

BACKGROUND: The number of opioid-related deaths in the United States has more than tripled over the past 7 years, with a steep increase beginning at the same time as the COVID-19 pandemic. There is an urgent need for novel treatment options that can help alleviate the individual and social effects of refractory opioid use disorder (OUD). Deep brain stimulation (DBS), an intervention that involves implanting electrodes in the brain to deliver electrical impulses, is one potential treatment. Currently in clinical trials for many psychiatric conditions, including OUD, DBS\'s use for psychiatric indications is not without controversy. Several studies have examined ethical issues raised by using DBS to counter treatment-resistant depression, obsessive-compulsive disorder, and eating disorders. In contrast, there has been limited literature regarding the use of DBS for OUD.
OBJECTIVE: This study aims to gain empirical neuroethical insights into public perceptions regarding the use of DBS for OUD, specifically via the analysis of web-based comments on news media stories about the topic.
METHODS: Qualitative thematic content analysis was performed on 2 Washington Post newspaper stories that described a case of DBS being used to treat OUD. A total of 292 comments were included in the analysis, 146 comments from each story, to identify predominant themes raised by commenters.
RESULTS: Predominant themes raised by commenters across the 2 samples included the hopes and expectations with treatment outcomes, whether addiction is a mental health disorder, and issues related to resource allocation. Controversial comments regarding DBS as a treatment method for OUD seemingly decreased when comparing the first printed newspaper story to the second. In comparison, the number of comments relating to therapeutic need increased over time.
CONCLUSIONS: The general public\'s perspectives on DBS as a treatment method for OUD elucidated themes via this qualitative thematic content analysis that include overarching sociopolitical issues, positions on the use of technology, and technological and scientific issues. A better understanding of the public perceptions around the use of DBS for OUD can help address misinformation and misperceptions about the use of DBS for OUD, and identify similarities and differences regarding ethical concerns when DBS is used specifically for OUD compared to other psychiatric disorders.

BACKGROUND: Cold atmospheric plasma (CAP) is a new therapeutic tool used to treat various skin diseases in humans and animals.
OBJECTIVE: To evaluate the effect of CAP in the treatment of canine acute otitis externa (AOE).
METHODS: Four client-owned golden retriever dogs with bilateral AOE.
METHODS: After cleaning with a commercial ear cleanser, right ears (STANDARD group) were treated with an antibiotic/antifungal/corticosteroid combination and left ears (CAP group) were treated with CAP every three days for a total of four treatments. Cytological score and otitis index score (OTIS)3 were recorded for each ear on Day (D)0, D10 and D15. At D10 and D15, owners and investigators recorded an overall assessment.
RESULTS: In both groups, OTIS3 and cytological score decreased over the study period. The overall assessment scale ranged from moderate to excellent in both groups.
CONCLUSIONS: Cold atmospheric plasma treatment showed equal therapeutic effect compared with a commercial topical anti-inflammatory and antimicrobial ear treatment.

UNASSIGNED: While most Helicobacter pylori-infected individuals remain asymptomatic throughout their lifetime, in a significant proportion, the resulting severe chronic gastritis drives the development of gastric cancer. In this study, we examine a new therapeutic target, a host potassium channel regulatory subunit, SUR2 (encoded by ABCC9), with potential to protect against H pylori-associated diseases.
UNASSIGNED: SUR2 gene (ABCC9) expression in human gastric biopsies was analyzed by quantitative polymerase chain reactions. Helicobacter-infected mice were administered the SUR2-channel agonists, pinacidil and nicorandil, then gastric tissues analyzed by histology, immunohistochemistry and quantitative polymerase chain reaction, and splenic tissues by enzyme-linked immunosorbent assays. In vitro studies were performed on human and mouse macrophages, human gastric epithelial cells and mouse splenocytes.
UNASSIGNED: ABCC9 expression in human and mouse stomachs is downregulated with H pylori infection. Treatment of Helicobacter-infected mice with SUR2 channel modulators, pinacidil or nicorandil, significantly reduced gastritis severity. In gastric epithelial cells, nicorandil-induced opening of the SUR2 channel increased intracellular K+ and prevented H pylori-mediated Ca2+ influx and downstream pro-inflammatory signaling.
UNASSIGNED: SUR2 is a novel host factor that regulates Helicobacter pathogenesis. Pharmacological targeting of SUR2 provides a potential approach for reducing the severity of H pylori-associated gastritis, without eradicating infection.

Alzheimer\'s disease (AD) is a condition in the brain that is marked by a gradual and ongoing reduction in memory, thought, and the ability to perform simple tasks. AD has a poor prognosis but no cure yet. Therefore, the need for novel models to study its pathogenesis and therapeutic strategies is evident, as the brain poorly recovers after injury and neurodegenerative diseases and can neither replace dead neurons nor reinnervate target structures. Recently, mesenchymal stem cells (MSCs), particularly those from the human olfactory mucous membrane referred to as the olfactory ecto-MSCs (OE-MSCs), have emerged as a potential avenue to explore in modeling AD and developing therapeutics for the disease due to their lifelong regeneration potency and facile accessibility. This review provides a comprehensive summary of the current literature on isolating OE-MSCs and delves into whether they could be reliable models for studying AD pathogenesis. It also explores whether healthy individual-derived OE-MSCs could be therapeutic agents for the disease. Despite being a promising tool in modeling and developing therapies for AD, some significant issues remain, which are also discussed in the review.

Multiple sclerosis (MS) is a chronic and progressive autoimmune disease of the central nervous system (CNS), with both genetic and environmental factors contributing to the pathobiology of the disease. While human leukocyte antigen (HLA) genes have emerged as the strongest genetic factor, consensus on environmental risk factors are lacking. Recently, trillions of microbes residing in our gut (microbiome) have emerged as a potential environmental factor linked with the pathobiology of MS as PwMS show gut microbial dysbiosis (altered gut microbiome). Thus, there has been a strong emphasis on understanding the factors (host and environmental) regulating the composition of the gut microbiota and the mechanism(s) through which gut microbes contribute to MS disease, especially through immune system modulation. A better understanding of these interactions will help harness the enormous potential of the gut microbiota as a therapeutic approach to treating MS.

Research into the anticancer activity of quantum-sized carbon dots (CDs) has emerged as a promising avenue in cancer research. This CDs delves into the opportunities and challenges associated with harnessing the potential of these nanostructures for combating cancer. Quantum-sized carbon dots, owing to their unique physicochemical properties, exhibit distinct advantages as potential therapeutic agents. Opportunities lie in their tunable size, surface functionalization capabilities, and biocompatibility, enabling targeted drug delivery and imaging in cancer cells. However, we include challenges, a comprehensive understanding of the underlying mechanisms, potential toxicity concerns, and the optimization of synthesis methods for enhanced therapeutic efficacy. A succinct summary of the state of the research in this area is given in this review, emphasizing the exciting possibilities and ongoing challenges in utilizing quantum-sized carbon dots as a novel strategy for cancer treatment.

BACKGROUND: There is a paucity of high-quality data to guide appropriate fresh frozen plasma transfusion with current recommendations based on consensus opinion. The limitations of the product and testing modalities are poorly understood with the rare but potentially serious side effects underappreciated. Combined this has resulted in the widespread misuse of FFP.
METHODS: Retrospective data capturing FFP transfusion within the 12-month period of April 1, 2022 and March 31, 2023 was entered by Australian health care providers. Appropriate transfusion was assessed by the adjudicators and defined as one in keeping with current recommendations. Descriptive and comparative analyses were performed using SAS Studio version 9.4.
RESULTS: During the study period, 935 FFP transfusion episodes were captured. The most frequent indications for FFP were massive hemorrhage 344 (37%), bleeding 141 (15%), and preoperative use 90 (10%). Males received 534 (60%) transfusions. Critical care specialists were the largest users of FFP, prescribing 568 (63%) of transfusions. FFP was used appropriately in 546 (61%) transfusions. However, when massive hemorrhage was excluded only 202 (37%) transfusions were appropriate. Patients with an INR <1.5 received 37% of transfusions. Transfusion associated adverse events were reported in 2% (15) of transfusions including two non-fatal anaphylactic reactions.
CONCLUSIONS: This audit assesses the appropriate use of FFP across all major clinical indications and provides the largest body of evidence of Australian plasma transfusion practices. It highlights the widespread misuse of FFP, which is predominantly guided by consensus recommendations due to a lack of high-quality data.
