Rugby union represents a high-risk sport for orofacial trauma due to its impact collisions and repetitive tackles. The aim of this study was to investigate the prevalence of orofacial trauma according to mouthguard use among a sample of Brazilian rugby union players.

An online questionnaire was sent to the 16 best rugby union clubs in Brazil. The questionnaire contained questions about the training history of each athlete, prevalence of orofacial trauma, and details about mouthguard use. Only participants who reported using a mouthguard were selected for this analysis.

A total of 244 individuals were included. The prevalence of orofacial trauma was 34.4%, and 61.9% of them did not wear a mouthguard at the time of the incident. The only type of mouthguard reported was the pre-fabricated ("boil and bite" and "ready-to-wear") type. A stronger association was observed between the reason for using a mouthguard and the outcome, whereas a lower proportion of trauma was observed among individuals who claimed mandatory mouthguard use at the gym/sport (20.0%). Time since the respondent started playing rugby union and who instructed them to use a mouthguard were not associated with orofacial trauma.

Prevalence of orofacial trauma was high among this sample of rugby union players from Brazil, even with the use of pre-fabricated mouthguards. This study encourages further investigation on the use of custom-made mouthguards in rugby union and the role of coach/physical educators to reduce the prevalence of orofacial trauma.

Diabetes aggravates the risk and severity of periodontitis, but the specific mechanism remains confused. Complement 3 (C3) is closely related to complications of type 2 diabetes (T2DM). In the present study, we concentrated on whether C3 mediates the development of periodontitis in T2DM.

Levels of C3 in blood and gingival crevicular fluid (GCF) of patients were measured first. A C3-knockout diabetic mouse model was established, real-time PCR, Western blotting and histological investigation were performed to evaluate the progress of periodontitis. Microcomputed tomography (micro-CT) and TRAP staining were performed to detect alveolar bone resorption. Immunofluorescence was performed to detect polarization of macrophages.

Our data showed that C3 levels were elevated in the blood and GCF of T2DM patients compared with non-diabetic individuals. Increased C3 was closely related to the upregulation of inflammatory cytokines including interleukin (IL)-1, IL-6 and tumour necrosis factor-alpha (TNF-α), as well as the decline of the bone volume density (BMD) and bone volume over total volume (BV/TV) of the alveolar bones in diabetic mice. The deletion of C3 inhibited inflammatory cytokines and rescued the decreased BMD and BV/TV of the alveolar bones. C3-mediated polarization of macrophages was responsible for the damage.

T2DM-related upregulation of C3 contributes to the development of periodontitis by promoting macrophages M1 polarization and inhibiting M2 polarization, triggering a pro-inflammatory effect on periodontal tissues.

To develop and evaluate an artificial intelligence triage system with high sensitivity for detecting referable diabetic retinopathy and maculopathy, while maintaining high specificity for non-referable disease, for clinical implementation within the New Zealand national diabetic retinopathy screening programme.

The THEIA™ artificial intelligence system for retinopathy and maculopathy screening, was developed at Toku Eyes using routinely collected retinal screening datasets from two of the largest district health boards in Auckland, New Zealand the Auckland District Health Board and the Counties Manukau District Health Board. All retinal images from consecutive individuals receiving retinal screening between January 2009 and December 2018 were used. Images were labelled as non-sight-threatening, potentially referable or sight-threatening for New Zealand implementation, or as referable (potentially referable + sight-threatening)/non-referable (non-sight-threatening) for global comparison.

Data from 32 354A, an artificial intelligence tool to assist in clinical decision-making, tailored to the needs of the New Zealand national diabetic screening programme, delivered high sensitivity for detecting referable retinopathy within the multi-ethnic New Zealand population with diabetes.Uric acid is a potential metabolite that serves as a danger-associated molecular pattern (DAMP) and induces inflammatory responses in sterile environments. Porphyromonas gingivalis is a keystone periodontopathogen, and its gingipain proteases play a critical role in the pathogenesis of periodontitis. In this study, we demonstrate that P. gingivalis gingipains play a role in THP-1 macrophage uric acid production by increasing the expression and activity of xanthine oxidoreductase (XOR). Uric acid sodium salt induces caspase-1 activation, cell death, and the expression of proinflammatory cytokines, including IL-1α, IL-6, and IL-8, in the human keratinocyte HOK-16B cell line. Our results suggest that gingipain-induced uric acid can mediate inflammation in periodontal tissue cells.

Men in the Northern Suburbs of Launceston, Tasmania, experience substantially poorer health outcomes and socio-economic disadvantage than most Australians. They are often described as "hard-to-reach," meaning difficult to engage in research, health promotion, policy and planning. This paper summarises the OPHELIA process to combine health literacy profiling with engagement of local men in health promotion, and their experience of the process and outcomes.

Interviews were conducted to explore the experiences of middle-aged men with the OPHELIA process and subsequent interventions.

Local data and health literacy profiling revealed experiences of isolation, lack of trust in the system, medication non-adherence, mental illness and chronic pain, which formed the basis for generation of ideas to improve their well-being and understanding of health. Tailored interventions were implemented, including suicide prevention, "Numeracy for Life" and "Healthy Sheds" courses. Interviews with six participants revealed that the process contributed to a sense of worth, social support and ability to break "old habits."

Prioritising the lived experience of "hard-to-reach" men through the OPHELIA process resulted in co-design of interventions that were valued by participants. SO WHAT? Health literacy profiling and genuine community engagement can empower vulnerable, under-represented communities to co-design, and engage in, health promotion.

Osseous-associated cervical spondylomyelopathy (OA-CSM) is a complex disorder with limited long-term survival. The longitudinal progression is currently unknown.

To describe changes on magnetic resonance imaging (MRI) over a 2-year minimum period. We hypothesized that spinal lesions would progress in the majority of dogs.

Eleven dogs previously diagnosed with OA-CSM were prospectively studied. Nine dogs were treated medically, whereas 2 were treated surgically.

Clinical and MRI follow-up were performed with a median time between MRI studies of 30 months (range, 24-54). Morphologic assessment evaluated vertebral canal stenosis, spinal cord compression, foraminal stenosis, and articular processes, among other variables. Morphometric assessment included vertebral canal area, spinal cord area, area of the articular processes, and foraminal height.

On follow-up MRI, the most affected site at the initial examination in medically treated dogs had progressed in 4 of 9 dogs, improved in 4, and was unchanged in 3. Clinically, all dogs except 2 medically treated dogs were unchanged to improve at follow-up. Initially, 50 of 60 (83.3%) intervertebral spaces had vertebral canal stenosis, whereas in the follow-up MRI 82.3% did. selleck products Of the sites with stenosis, 45.7% were unchanged, 18.6% improved, and 38.9% worsened. Morphometry identified significant decreases in vertebral canal and spinal cord areas at C4-C5 through C6-C7, and significant progression of articular process irregularities at C3-C4 and C6-C7.

This long-term follow-up study of dogs with OA-CSM did not identify clinical or MRI progression of lesions in the majority of dogs.

This study reports the cloning of a blackleg R gene from Brassica napus (canola), Rlm9, which encodes a wall-associated kinase-like (WAKL) protein, a newly discovered class of race-specific plant RLK resistance genes. Rlm9 provides race-specific resistance against isolates of Leptosphaeria maculans carrying the corresponding avirulence gene AvrLm5-9, representing only the second WAKL-type R gene described to date. The Rlm9 protein is predicted to be cell membrane-bound and while not conclusive, our work did not indicate direct interaction with AvrLm5-9. Rlm9 forms part of a distinct evolutionary family of RLK proteins in B. napus, and while little is yet known about WAKL function, the Brassica-Leptosphaeria pathosystem may prove to be a model system by which the mechanism of fungal avirulence protein recognition by WAKL-type R genes can be determined.Accumulating evidence suggests that metformin reduces the incidence and mortality of colorectal cancer (CRC). However, underlying mechanisms have not been fully clarified. The aim of this study was to examine the pathological characteristics of resected CRC from patients treated with metformin for type 2 diabetes mellitus (DM). In total, 267 patients with DM underwent curative colectomy for Stage I-III CRC and 53 (19.9%) patients had been treated medically including metformin. Pathological N-stage was significantly lower in metformin-treated patients (P less then .05) with prolonged disease-free survival (DFS) (P less then .05). Immunohistochemistry showed that the densities of CD3(+) and CD8(+) tumor-infiltrating lymphocytes (TILs) in the invasive front area were significantly higher in 40 patients treated with metformin compared with propensity score matched cases without metformin (P less then .05). The density of tertiary lymphoid structures (TLS) in tumor stroma was markedly increased in metformin-treated patients (P less then .
