Type 2 idiopathic macular telangiectasia (MacTel-2) is a progressive adult-onset macular disease associated with bilateral perifoveal vascular changes, Muller cell degeneration and increased blood-retinal barrier permeability. The pathophysiological mechanisms of MacTel-2 remain unclear, however it was previously reported that anti-retinal antibodies in MacTel-2 patients are a significant feature of the disease. In this study, we aimed to compare the prevalence of anti-retinal antibodies in patients MacTel-2, healthy controls and patients with other retinal diseases. MacTel-2 patients diagnosed with multimodal imaging were enrolled and their disease severities were graded using spectral-domain optical coherence tomography. For comparison, patients with age-related macular degeneration …

Glycomic Biomarkers Are Instrumental For Suboptimal Health Status Management In The Context Of Predictive, Preventive, And Personalized Medicine, Xiaoni Meng, Biyan Wang, Xizhu Xu, Manshu Song, Haifeng Hou, Wei Wang, Youxin Wang

Research outputs 2022 to 2026

Objectives: Suboptimal health status (SHS), a reversible borderline condition between optimal health status and disease, has been recognized as a main risk factor for non-communicable diseases (NCDs). From the standpoint of predictive, preventive, and personalized medicine (PPPM/3PM), the early detection of SHS provides a window of opportunity for targeted prevention and personalized treatment of NCDs. Considering that immunoglobulin G (IgG) N-glycosylation levels are associated with NCDs, it can be speculated that IgG N-glycomic alteration might occur at the SHS stage.

Methods: A case–control study was performed and it consisted of 124 SHS individuals and 124 age-, gender-, and body mass …

Modulating Tumour Hypoxia In Prostate Cancer Through Exercise: The Impact Of Redox Signalling On Radiosensitivity, Malcolm Brown, Amélie Rébillard, Nicolas H. Hart, Dominic O’Connor, Gillian Prue, Joe M. O’Sullivan, Suneil Jain

Research outputs 2022 to 2026

Prostate cancer is a complex disease affecting millions of men globally. Radiotherapy (RT) is a common treatment modality although treatment efficacy is dependent upon several features within the tumour microenvironment (TME), especially hypoxia. A hypoxic TME heightens radioresistance and thus disease recurrence and treatment failure continues to pose important challenges. However, the TME evolves under the influence of factors in systemic circulation and cellular crosstalk, underscoring its potential to be acutely and therapeutically modified. Early preclinical evidence suggests exercise may affect tumour growth and some of the benefits drawn, could act to radiosensitise tumours to treatment. Intracellular perturbations in skeletal …

Survivorship Research For People With Metastatic Or Advanced Cancer: A Time For Action, Andrea L. Smith, Nicolas H. Hart, Michael Jefford, Raymond J. Chan

Research outputs 2022 to 2026

Over recent decades, survival outcomes for people diagnosed with cancer have changed dramatically, with approximately 20% improvement in five-year relative survival rates in high-income countries including the United States and Australia. Regardless of regions, there is a decrease in overall cancer mortality rate of about 1% per year. Likewise, the cancer disease trajectory has changed. The traditional linear cancer trajectory in which a patient moves from cancer diagnosis through to a binary outcome (cure or death)—is no longer applicable and does not adequately describe the complexity of experience for many people. Indeed, the availability of targeted therapies and immunotherapies has …

A retrospective analysis of routine countermovement jump (CMJ) testing, a coupled eccentric-concentric (stretch-shorten-cycle: SSC) movement, was performed in female elite alpine skiers with anterior cruciate ligament (ACL) reconstruction (ACLR) and without ACLR. A total of 567 tests obtained from the daily training environment were analyzed in 41 elite female athletes (non-injured control: n = 30, ACLR: n = 17), including n = 6 athletes with pre-injury data, between 16 and 32 years of age from alpine ski racing (n = 32) and skier cross (n = 9). Bilateral CMJ testing was conducted on a dual force plate system, and the …

Research outputs 2022 to 2026

Background

The genotoxic and cancerogenic impacts of population-wide cannabinoid exposure remains an open but highly salient question. The present report examines these issues from a continuous bivariate perspective with subsequent reports continuing categorical and detailed analyses.

Methods

Age-standardized state census incidence of 28 cancer types (including “All (non-skin) Cancer”) was sourced using SEER*Stat software from Centres for Disease Control and National Cancer Institute across US states 2001–2017. It was joined with drug exposure data from the nationally representative National Survey of Drug Use and Health conducted annually by the Substance Abuse and Mental Health Services Administration 2003–2017, response rate 74.1%. …

Research outputs 2022 to 2026

Background: As the cannabis-cancer relationship remains an important open question epidemiological investigation is warranted to calculate key metrics including Rate Ratios (RR), Attributable Fractions in the Exposed (AFE) and Population Attributable Risks (PAR) to directly compare the implicated case burden between emerging cannabinoids and the established carcinogen tobacco. Methods: SEER*Stat software from Centres for Disease Control was used to access age-standardized state census incidence of 28 cancer types (including “All (non-skin) Cancer”) from National Cancer Institute in US states 2001–2017. Drug exposures taken from the National Survey of Drug Use and Health 2003–2017, response rate 74.1%. Federal seizure data provided …

An Investigation Of A Novel Broad Autism Phenotype: Increased Facial Masculinity Among Parents Of Children On The Autism Spectrum, Diana Weiting Tan, Syed Zulqarnain Gilani, Gail A. Alvares, Ajmal Mian, Andrew J. O. Whitehouse, Murray T. Maybery

Research outputs 2022 to 2026

The broad autism phenotype commonly refers to sub-clinical levels of autistic-like behaviour and cognition presented in biological relatives of autistic people. In a recent study, we reported findings suggesting that the broad autism phenotype may also be expressed in facial morphology, specifically increased facial masculinity. Increased facial masculinity has been reported among autistic children, as well as their non-autistic siblings. The present study builds on our previous findings by investigating the presence of increased facial masculinity among non-autistic parents of autistic children. Using a previously established method, a 'facial masculinity score' and several facial distances were calculated for each three-dimensional …

Research outputs 2022 to 2026

Background: The epidemiology of cannabinoid-related cancerogenesis has not been studied with cutting edge epidemiological techniques. Building on earlier bivariate papers in this series we aimed to conduct pathfinding studies to address this gap in two tumours of the reproductive tract, prostate and ovarian cancer. Methods: Age-standardized cancer incidence data for 28 tumour types (including “All (non-skin) Cancer”) was sourced from Centres for Disease Control and National Cancer Institute using SEER*Stat software across US states 2001–2017. Drug exposure was sourced from the nationally representative household survey National Survey of Drug Use and Health conducted annually by the Substance Abuse and Mental …
