简介：AbstractOdontogenic sinusitis (ODS) is more common than historically reported, and is under-represented in the sinusitis literature. ODS is distinct from rhinosinusitis in that it is infectious sinusitis from an infectious dental source or a complication from dental procedures, and most commonly presents unilaterally. ODS clinical features, microbiology, and diagnostic and treatment paradigms are also distinct from rhinosinusitis. ODS evaluation and management should generally be conducted by both otolaryngologists and dental providers, and clinicians must be able to suspect and confirm the condition. ODS suspicion is driven by certain clinical features like unilateral maxillary sinus opacification on computed tomography, overt maxillary dental pathology on computed tomography, unilateral middle meatal purulence on nasal endoscopy, foul smell, and odontogenic bacteria in sinus cultures. Otolaryngologists should confirm the sinusitis through nasal endoscopy by assessing for middle meatal purulence, edema, or polyps. Dental providers should confirm dental pathology through appropriate examinations and imaging. Once ODS is confirmed, a multidisciplinary shared decision-making process should ensue to discuss risks and benefits of the timing and different types of dental and sinus surgical interventions. Oral antibiotics are generally ineffective at resolving ODS, especially when there is treatable dental pathology. When both the dental pathology and sinusitis are addressed, resolution can be expected in 90%-100% of cases. For treatable dental pathology, while primary dental treatment may resolve the sinusitis, a significant percentage of patients still require endoscopic sinus surgery. For patients with significant sinusitis symptom burdens, primary endoscopic sinus surgery is an option to resolve symptoms faster, followed by appropriate dental management. More well-designed studies are necessary across all areas of ODS.

简介：AbstractObjective:To describe the issues related to the assignment of surgical wound classification as it pertains to Otolaryngology—Head & Neck surgery, and to present a simple framework by which providers can assign wound classification.Data Sources:Literature review.Conclusion:Surgical wound classification in its current state is limited in its utility. It has recently been disregarded by major risk assessment models, likely due to inaccurate and inconsistent reporting by providers and operative staff. However, if data accuracy is improved, this metric may be useful to inform the risk of surgical site infection. In an era of quality-driven care and reimbursement, surgical wound classification may become an equally important indicator of quality.

简介：AbstractObjective:The aim of this work was to explore the feasibility of in vivo and non-invasive monitoring of deuterium/hydrogen (2H/1H) exchange at the metabolic level upon exposure to heavy water (2H2O).Methods:The healthy female mice were randomly assigned to two groups after day 0 when both mice received standard drinking water. The treated mouse was fed with 2H2O (80%, v/v) and the control mouse fed with standard drinking water (H2O) over next 13 days. Real-time mass spectrometric analysis of volatile metabolism emitted through breathing and the skin was performed on days 1, 2, 3, 10, 12, and 13. Animal experiment was approved by the Laboratory Animal Ethics Committee of Jinan University (approval No. 20161117163322) on October 29, 2021.Results:We observed a replacement of 1H by 2H in 52 mass spectral features (60 2H/1H isotopologue pairs) for the mouse fed with 2H2O, but not for the control mouse. These included pyruvic acid and lactic acid, lysine and methyl-lysine as well as short-chain fatty acids comprising acetic acid, propionic acid, butyric acid and valeric acid.Conclusion:Secondary electrospray ionization-high resolution mass spectrometry allows monitoring in vivo2H-incorporation of metabolites in a non-invasive and real-time setup and opens new opportunities to use 2H tracing to extend current metabolic studies, especially those with a focus on anaerobic glycolysis, lysine methylation and gut microbiome via monitoring of short-chain fatty acids.

简介：摘要MARCH（membrane-associated RING-CH fingerprotein）家族是在21世纪初发现的一类E3泛素连接酶，有11个家族成员，在生物体内通过对底物蛋白进行泛素化修饰从而发挥多种调控作用。膜相关RING-CH蛋白2（membrane-associated RING-CH protein Ⅱ），简称MARCH2，常见的靶点有转铁蛋白受体（transferrin receptor，TfR）、突触融合蛋白6（syntaxin 6，STX-6）、CD86（B7-2）、人DLG1（discs large tumour suppressor）和囊性纤维跨膜传导调节因子（cystic fibrosis transmembrane conductance regulator，CFTR）以及β2肾上腺素能受体（β2-adrenergic receptors，β2-AR），在病毒免疫逃避、肿瘤发生及激动剂脱敏等方面发挥着作用。其主要通过泛素化修饰在哺乳动物的蛋白修饰及泛素化降解过程，发挥着举足轻重的作用，尤其是调控细胞内囊泡运输的蛋白及表面受体。但目前对MARCH2的功能研究仍有许多空白之处尚待填补。本文就MARCH2的起源、结构及功能进行阐述，为后续基础及临床研究提供一定的依据。
