In response to the increase in non-medical vaccine exemptions (NME), many states have adopted education mandates (EM), required vaccine education for parents requesting NMEs for their school-age children, but these EMs vary greatly in implementation. In order to learn about the administrative aspects of each state’s EM, we interviewed fourteen health department officials from nine states with EMs. Interviews were conducted over the phone, transcribed by a professional transcription service, and double-coded using NVivo 12 by two members of the study staff. The coding resulted in 3698 comments overall, 98.5% inter-coder reliability, and a κ statistic of 0.691. We found no consistent format for content delivery, and methods used included in-person dialogs, web-based education, and video modules. Content of the education is not standardized, and education length ranges from 15 to 60 minutes. Four major themes about the EM policies emerged: (1) the use of EMs to eliminate “convenience exemptions;” (2) the importance of health department communication with health-care providers; (3) facilitators and barriers to implementation; and (4) the positive recommendation for other states to adopt EM policies. We concluded that current EM implementation varies greatly, but officials in states which have adopted EMs for parents requesting NMEs for school-entry vaccinations overwhelmingly recommend other states to adopt them as well. Key features of successful programs may include conversations with parents requesting NMEs and strong communication channels with health-care providers. Systematic tracking of vaccine status after exemption requests and education is necessary to quantitatively determine the effectiveness of EM programs.

Evidence is accruing of associations between male reproductive health disorders and chronic diseases such as coronary heart disease and type 2 diabetes. The links between reproductive health and general health are under-recognised by medical practitioners and the general public. Windows of opportunity exist for a more holistic approach to men's health when men present with reproductive health symptoms (such as erectile dysfunction) or the reproductive implications of chronic disease are recognised. Further men's health research is needed in Australia to guide policy, innovative health promotion, and clinical practice. [ABSTRACT FROM AUTHOR]

Abstract Background The relationship between reproductive health disorders and lifestyle factors in middle-aged and older men is not clear. The aim of this study is to describe lifestyle and biomedical associations as possible causes of erectile dysfunction (ED), prostate disease (PD), lower urinary tract symptoms (LUTS) and perceived symptoms of androgen deficiency (pAD) in a representative population of middle-aged and older men, using the Men in Australia Telephone Survey (MATeS). Methods A representative sample (n = 5990) of men aged 40+ years, stratified by age and State, was contacted by random selection of households, with an individual response rate of 78%. All men participated in a 20-minute computer-assisted telephone interview exploring general and reproductive health. Associations between male reproductive health disorders and lifestyle and biomedical factors were analysed using multivariate logistic regression (odds ratio [95% confidence interval]). Variables studied included age, body mass index, waist circumference, smoking, alcohol consumption, physical activity, co-morbid disease and medication use for hypertension, high cholesterol and symptoms of depression. Results Controlling for age and a range of lifestyle and co-morbid exposures, sedentary lifestyle and being underweight was associated with an increased likelihood of ED (1.4 [1.1-1.8]; 2.9 [1.5-5.8], respectively) and pAD (1.3 [1.1-1.7]; 2.7 [1.4-5.0], respectively. Diabetes and cardiovascular disease were both associated with ED, with hypertension strongly associated with LUTS and pAD. Current smoking (inverse association) and depressive symptomatology were the only variables independently associated with PD. All reproductive disorders showed consistent associations with depression (measured either by depressive symptomatology or medication use) in both age-adjusted and multivariate analyses. Conclusion A range of lifestyle factors, more often associated with chronic disease, were significantly associated with male reproductive health disorders. Education strategies directed to improving general health may also confer benefits to male reproductive health.

Background: Japanese knotweed (Reynoutria japonica var. japonica), a problematic invasive species, has a wide geographical distribution. We have previously shown the potential for attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy and chemometrics to segregate regional differentiation between Japanese knotweed plants. However, the contribution of environment to spectral differences remains unclear. Herein, the response of Japanese knotweed to varied environmental habitats has been studied. Eight unique growth environments were created by manipulation of the red: far-red light ratio (R: FR), water availability, nitrogen, and micronutrients. Their impacts on plant growth, photosynthetic parameters, and ATR-FTIR spectral profiles, were explored using chemometric techniques, including principal component analysis (PCA), linear discriminant analysis, support vector machines (SVM) and partial least squares regression. Key wavenumbers responsible for spectral differences were identified with PCA loadings, and molecular biomarkers were assigned. Partial least squared regression (PLSR) of spectral absorbance and root water potential (RWP) data was used to create a predictive model for RWP., Results: Spectra from plants grown in different environments were differentiated using ATR-FTIR spectroscopy coupled with SVM. Biomarkers highlighted through PCA loadings corresponded to several molecules, most commonly cell wall carbohydrates, suggesting that these wavenumbers could be consistent indicators of plant stress across species. R: FR most affected the ATR-FTIR spectra of intact dried leaf material. PLSR prediction of root water potential achieved an R2 of 0.8, supporting the potential use of ATR-FTIR spectrometers as sensors for prediction of plant physiological parameters., Conclusions: Japanese knotweed exhibits environmentally induced phenotypes, indicated by measurable differences in their ATR-FTIR spectra. This high environmental plasticity reflected by key biomolecular changes may contribute to its success as an invasive species. Light quality (R: FR) appears critical in defining the growth and spectral response to environment. Cross-species conservation of biomarkers suggest that they could function as indicators of plant-environment interactions including abiotic stress responses and plant health., (© 2024.

Plant hormones are important in the control of physiological and developmental processes including seed germination, senescence, flowering, stomatal aperture, and ultimately the overall growth and yield of plants. Many currently available methods to quantify such growth regulators quickly and accurately require extensive sample purification using complex analytic techniques. Herein we used ultra-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) to create and validate the prediction of hormone concentrations made using attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectral profiles of both freeze-dried ground leaf tissue and extracted xylem sap of Japanese knotweed ( Reynoutria japonica ) plants grown under different environmental conditions. In addition to these predictions made with partial least squares regression, further analysis of spectral data was performed using chemometric techniques, including principal component analysis, linear discriminant analysis, and support vector machines (SVM). Plants grown in different environments had sufficiently different biochemical profiles, including plant hormonal compounds, to allow successful differentiation by ATR-FTIR spectroscopy coupled with SVM. ATR-FTIR spectral biomarkers highlighted a range of biomolecules responsible for the differing spectral signatures between growth environments, such as triacylglycerol, proteins and amino acids, tannins, pectin, polysaccharides such as starch and cellulose, DNA and RNA. Using partial least squares regression, we show the potential for accurate prediction of plant hormone concentrations from ATR-FTIR spectral profiles, calibrated with hormonal data quantified by UHPLC-HRMS. The application of ATR-FTIR spectroscopy and chemometrics offers accurate prediction of hormone concentrations in plant samples, with advantages over existing approaches.

Background: Several studies have highlighted poor compliance with surveillance colonoscopy guidelines. The National Health and Medical Research Council (NHMRC) guidelines were revised in 2018 and were more complex than the previous iteration (2011). The aim of this study was to determine the impact of 2018 NHMRC polyp surveillance guidelines on compliance with colonoscopy surveillance intervals., Methods: A multicentre retrospective clinical audit was conducted between January 2020 and February 2021. Patients awaiting a colonoscopy for polyp surveillance at two public tertiary care hospitals in South Australia were included. Compliance rates of recommended polyp surveillance colonoscopy intervals after implementation of 2018 NHMRC guidelines were compared with 2011 NHMRC guidelines. The projected impact on colonoscopy bookings of the change in guideline intervals was modelled to 5 and 10 years, factoring in differences in compliance., Results: Of 3996 patients awaiting colonoscopy services at two public hospitals in South Australia, 1984 patients (60% male, median age 61 years) were waitlisted for polyp surveillance. Overall compliance with surveillance guidelines was >60%. Implementation of the 2018 NHMRC guidelines significantly reduced compliance from 65.8% (2011 guidelines) to 50.8% (2018) (χ 2 <0.001, OR 0.5). Modelling projections to 5 and 10 years demonstrated that application of the 2018 guidelines significantly increases the projected number of colonoscopy bookings per year., Conclusion: The revised 2018 NHMRC guidelines have resulted in significantly poorer compliance post-implementation, possibly due to their increased complexity. This has potential to increase the surveillance colonoscopy waiting list burden., (© 2022 Royal Australasian College of Surgeons.)

Extreme weather and globalisation leave our climate vulnerable to invasion by alien species, which have negative impacts on the economy, biodiversity, and ecosystem services. Rapid and accurate identification is key to the control of invasive alien species. However, visually similar species hinder conservation efforts, for example hybrids within the Japanese Knotweed complex.We applied the novel method of ATR-FTIR spectroscopy combined with chemometrics (mathematics applied to chemical data) to historic herbarium samples, taking 1580 spectra in total. Samples included five species from within the interbreeding Japanese Knotweed complex (including three varieties of Japanese Knotweed), six hybrids and five species from the wider Polygonaceae family. Spectral data from herbarium specimens were analysed with several chemometric techniques: support vector machines (SVM) for differentiation between plant types, supported by ploidy levels; principal component analysis loadings and spectral biomarkers to explore differences between the highly invasive Reynoutria japonica var. japonica and its non-invasive counterpart Reynoutria japonica var. compacta; hierarchical cluster analysis (HCA) to investigate the relationship between plants within the Polygonaceae family, of the Fallopia, Reynoutria, Rumex and Fagopyrum genera.ATR-FTIR spectroscopy coupled with SVM successfully differentiated between plant type, leaf surface and geographical location, even in herbarium samples of varying age. Differences between Reynoutria japonica var. japonica and Reynoutria japonica var. compacta included the presence of two polysaccharides, glucomannan and xyloglucan, at higher concentrations in Reynoutria japonica var. japonica than Reynoutria japonica var. compacta. HCA analysis indicated that potential genetic linkages are sometimes masked by environmental factors; an effect that can either be reduced or encouraged by altering the input parameters. Entering the absorbance values for key wavenumbers, previously highlighted by principal component analysis loadings, favours linkages in the resultant HCA dendrogram corresponding to expected genetic relationships, whilst environmental associations are encouraged using the spectral fingerprint region.The ability to distinguish between closely related interbreeding species and hybrids, based on their spectral signature, raises the possibility of using this approach for determining the origin of Japanese knotweed infestations in legal cases where the clonal nature of plants currently makes this difficult and for the targeted control of species and hybrids. These techniques also provide a new method for supporting biogeographical studies., Competing Interests: A commercial funder, Phlorum Ltd, provided consumables funding for CAH’s studentship, access to which was mediated by the Centre for Global Eco-Innovation. This does not alter our adherence to PLOS ONE policies on sharing data and materials.

Background: Japanese knotweed (R. japonica var japonica) is one of the world's 100 worst invasive species, causing crop losses, damage to infrastructure, and erosion of ecosystem services. In the UK, this species is an all-female clone, which spreads by vegetative reproduction. Despite this genetic continuity, Japanese knotweed can colonise a wide variety of environmental habitats. However, little is known about the phenotypic plasticity responsible for the ability of Japanese knotweed to invade and thrive in such diverse habitats. We have used attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy, in which the spectral fingerprint generated allows subtle differences in composition to be clearly visualized, to examine regional differences in clonal Japanese knotweed., Results: We have shown distinct differences in the spectral fingerprint region (1800-900 cm - 1 ) of Japanese knotweed from three different regions in the UK that were sufficient to successfully identify plants from different geographical regions with high accuracy using support vector machine (SVM) chemometrics., Conclusions: These differences were not correlated with environmental variations between regions, raising the possibility that epigenetic modifications may contribute to the phenotypic plasticity responsible for the ability of R. japonica to invade and thrive in such diverse habitats., (© 2021.

Introduction: An understanding of contextual factors that influence whether general practitioners advise their patients to be screened for colorectal cancer (CRC) might guide interventions to increase screening participation from its persistently low rate. We report on the use of a theory-based tool to explore contextual factors that might influence implementation of a novel quality improvement (QI) intervention to increase CRC screening in general practice (CRC-QI). The objective was to identify and incorporate strategies into the intervention that will enable flexible implementation across different practice settings., Study Type: A qualitative study to explore contextual facilitators of, and barriers to, the implementation of a novel CRC-QI intervention., Methods: Eighteen staff, from three self-nominated general practices, participated in focus group discussions. The Consolidated Framework for Implementation Research (CFIR), which included constructs relevant to CRC screening in primary care, guided the formative evaluation. Findings were aligned to the CFIR model using a deductive thematic analysis., Results: Contextual facilitators of, and barriers to, the implementation of the CRC-QI intervention were identified in each CFIR domain and CRC-relevant construct. Five consistent themes were identified that potentially influence elements of the CRC-QI intervention: priority setting and incentives, information technology, patient-level barriers, clinical practice, and the National Bowel Cancer Screening Program (NBCSP). Participants proposed that incentive payments and NBCSP policy changes (outer-setting strategies) would facilitate organisational change (inner-setting strategies) and the effective implementation of the CRC-QI intervention., Conclusion: There may be an opportunity to better engage general practice in CRC screening via outer-setting constructs that support existing clinical practice. For example, improvements to the National Cancer Screening Register and Quality Improvement Incentive - Practice Incentives Program (PIP) could be made without altering the NBCSP design., Competing Interests: None declared

Early diagnosis of colorectal cancer (CRC) and access to optimal treatment achieves optimal cancer outcomes. However, CRC survival inequalities persist with a lower survival rate for older patients (≥65 years). Although the reasons for poorer cancer survival in older people are complex, evidence suggests that these patients are less likely to receive best practice care as indicated by access to multidisciplinary team (MDT) care. Three electronic databases were systematically searched to examine factors that affect access to, and clinical decision-making, in the context of MDT care of older people with CRC. We included studies reporting empirical data relating to predictors for a patient's case being discussed at a MDT meeting and/or factors that impact treatment decision-making during the meeting. From 303 returned titles and abstracts, eighteen articles were reviewed. Eight studies specifically selected older patients, with eligibility criteria varying from ≥65 to ≥80 years. Five articles explored predictors of MDT access, with all articles identifying age as a negative, and advanced stage as a positive predictor of MDT discussion. Fourteen studies explored factors that influenced the MDT decision-making process, with older age and presence of comorbid disease negatively influencing treatment decisions (cases less often discussed and/or treatment not recommended). A few studies identified access to a MDT discussion as an independent predictor for CRC treatment. Access to the MDT process for older patients with a CRC diagnosis should be based on relevant geriatric domains rather than on chronological age alone, which is expected to allow more appropriate clinical decision-making and reduce treatment inequities for older patients with cancer., Competing Interests: Declaration of Competing Interest None., (Copyright © 2019 Elsevier Inc.

Background: Understanding factors causing variation in family physicians/general practitioners (GPs) screening knowledge, understanding and support of organised population-based colorectal cancer (CRC) programs can direct interventions that maximise the influence of a CRC screening recommendation from a GP. This study aims to assess contextual factors that influence knowledge and quality improvement (QI) practice directed to CRC screening in Australian general practice., Methods: A convenience sample of anonymous general practice staff from all Australian states and territories completed a web-based survey. Multivariate analyses assessed the association between CRC screening knowledge and QI-CRC practice scores and patient, organisational and environmental-level contextual factors.  Results: Of 1,013 survey starts, 918 respondents (90.6%) completed the survey. Respondents less likely to recommend FOBT screening had lower knowledge and QI practice scores directed to CRC screening. Controlling for individual and practice characteristics, respondents' rating of the Australian National Bowel Cancer Screening Program (NBCSP) support for preventive care, attending external education, and sufficient practice resources to implement QI practice (generally) were the strongest factors associated with QI practice directed towards CRC screening. Knowledge scores were less amenable to the influence of contextual factors explored., Conclusion: More active engagement of family medicine/general practice to improve screening promotion could be achieved through better QI resourcing without changing the fundamental design of population-based CRC screening programs.

Primary health care (PHC) plays a vital support role in organised colorectal cancer (CRC) screening programs by encouraging patient participation and ensuring timely referral for diagnostic assessment follow up. A systematic scoping review of the current evidence was conducted to inform strategies that better engage the PHC sector in organised CRC screening programs. Articles published from 2005 to November 2019 were searched across five databases. Evidence was synthesised and interventions that specifically require PHC involvement were mapped to stages of the CRC screening pathway. Fifty-seven unique studies were identified in which patient, provider and system-level interventions align with defined stages of the CRC screening pathway: namely, identifying/reminding patients who have not responded to CRC screening (non-adherence) (n=46) and follow up of a positive screen referral (n=11). Self-management support initiatives (patient level) and improvement initiatives (system level) demonstrate consistent benefits along the CRC screening pathway. Interventions evaluated as part of a quality-improvement process tended to report effectiveness; however, the variation in reporting makes it difficult to determine which elements contributed to the overall study outcomes. To maximise the benefits of population-based screening programs, better integration into existing primary care services can be achieved through targeting preventive and quality care interventions along the entire screening pathway.

Background: The Australian National Bowel Cancer Screening Program (NBCSP) provides biennial immunochemical faecal occult blood test (iFOBT) screening for people aged 50-74 years. Previous work has quantified the number of colorectal cancer (CRC) deaths prevented by the NBCSP and has shown that it is cost-effective. With a 40% screening participation rate, the NBCSP is currently underutilised and could be improved by increasing program participation, but the maximum appropriate level of spending on effective interventions to increase adherence has not yet been quantified., Objectives: To estimate (i) reductions in CRC cases and deaths for 2020-2040 attributable to, and (ii) the threshold for cost-effective investment (TCEI) in, effective future interventions to improve participation in the NBCSP., Methods: A comprehensive microsimulation model, Policy1-Bowel, was used to simulate CRC natural history and screening in Australia, considering currently reported NBCSP adherence rates, i.e. iFOBT participation (∼40%) and diagnostic colonoscopy assessment rates (∼70%). Australian residents aged 40-74 were modelled. We evaluated three scenarios: (1) diagnostic colonoscopy assessment increasing to 90%; (2) iFOBT screening participation increasing to 60% by 2020, 70% by 2030 with diagnostic assessment rates of 90%; and (3) iFOBT screening increasing to 90% by 2020 with diagnostic assessment rates of 90%. In each scenario, we estimated CRC incidence and mortality, colonoscopies, costs, and TCEI given indicative willingness-to-pay thresholds of AUD$10,000-$30,000/LYS., Results: By 2040, age-standardised CRC incidence and mortality rates could be reduced from 46.2 and 13.5 per 100,000 persons, respectively, if current participation rates continued, to (1) 44.0 and 12.7, (2) 36.8 and 8.8, and (3) 31.9 and 6.5. In Scenario 2, 23,000 lives would be saved from 2020-2040 vs current participation rates. The estimated scenario-specific TCEI (Australian dollars or AUD$/year) to invest in interventions to increase participation, given a conservative willingness-to-pay threshold of AUD$10,000/LYS, was (1) AUD$14.9M, (2) AUD$72.0M, and (3) AUD$76.5M., Conclusion: Significant investment in evidence-based interventions could be used to improve NBCSP adherence and help realise the program's potential. Such interventions might include mass media campaigns to increase program participation, educational or awareness interventions for practitioners, and/or interventions resulting in improvements in referral pathways. Any set of interventions which achieves at least 70% iFOBT screening participation and a 90% diagnostic assessment rate while costing under AUD$72 million annually would be highly cost-effective (

Many countries have identified a need for targeted men's health promotion within primary health care as part of broader men's health policy. Primary health care nurses are well placed to deliver such services but may lack the requisite skills. The aim of this study was to pilot the delivery phase of an education program and evaluate a train-the-trainer approach for delivering men's health education to primary health care nurses. The 8-h train-the-trainer workshop was designed to equip nurses to deliver men's health education workshops to peers. Surveys of facilitators (n = 18) and peer workshop participants (n = 98) evaluated their level of confidence in men's health and knowledge and skills in men's health promotion. After completing the train-the-trainer workshop, most facilitators expressed confidence (92%), and all indicated sufficient knowledge and access to resources to deliver a peer workshop. All agreed that the module was sufficiently flexible to suit their local setting. Following the peer education workshop, facilitators and workshop participants reported high levels of confidence and knowledge in men's health promotion. This pilot evaluation suggests train-the-trainer is an effective model to deliver men's health education across a range of settings, with a flexible approach to raising awareness and improving the skills of primary health care nurses in men's health promotion., (Copyright © 2016 Elsevier Ltd.

Background: Enhancing a medical school curriculum with new men's health teaching and learning requires an understanding of the local capacity and the facilitators and barriers to implementing new content, and an approach that accommodates the systemic and cultural differences between medical schools., Methods: A formative evaluation was undertaken to determine the perspectives of key informants (academics, curriculum developers) from four Australian medical schools about the strategies needed to enhance their curriculum with men's health teaching and learning. Through semi-structured questioning with 17 key informants, interviewees also described the contextual barriers and facilitators to incorporating new topic areas into existing curriculum. Interviews were recorded with consent, transcribed verbatim, and analysed by two researchers to identify key themes., Results: Interviewees were enthusiastic about incorporating men's health content through a men's health curriculum framework but highlighted the need for systems to assist in identifying gaps in their current curriculum where the men's health topics could be integrated. The student experience was identified as a key driver for men's health teaching and learning. Furthermore, core men's health clinical outcomes needed to be defined and topic areas vertically integrated across the curricula. This would ensure that students were appropriately equipped with the skills and knowledge for subsequent clinical practice in a range of geographical settings. Interviewees consistently suggested that the best implementation strategy is to have someone 'on the ground' to work directly with medical school staff and champion the men's health discipline. Providing mechanisms for sharing knowledge and resources across medical schools was highlighted to facilitate implementation, particularly for those medical schools with limited men's health teaching resources., Conclusions: Despite the unanimous support for men's health teaching and learning, the evaluation highlighted that the student experience must be recognised as paramount when integrating new topic areas into an already packed curriculum. A community of practice, where medical schools share relevant resources and knowledge, could help to ensure a commonality of student experience with respect to men's health learning in medical schools across different geographical settings and with different levels of resourcing. Such an approach could also be adapted to other areas of curriculum enhancement.

Recurrent meningiomas constitute an uncommon but significant problem after standard (surgery and radiation) therapy failure. Current chemotherapies (hydroxyurea, RU-486, and interferon-α) are only of marginal benefit. There is an urgent need for more effective treatments for meningioma patients who have failed surgery and radiation therapy. Limonin, Tangeritin, Zerumbone, 6-Gingerol, Ganoderic Acid A, and Ganoderic Acid DM are some of the plant derivatives that have anti-tumorgenic properties and cause cell death in meningioma cells in vitro. Due to its ease of administration, long-term tolerability, and low incidence of long-term side effects, we explored its potential as a therapeutic agent against meningiomas by examining their efficacy in vitro against meningioma cells. Treatment effects were assessed using MTT assay, Western blot analysis, caspases assay, and DNA fragmentation assay. Results indicated that treatments of IOMM-Lee and CH157MN meningioma cells with Limonin, Tangeritin, Zerumbone, 6-Gingerol, Ganoderic Acid A, and Ganoderic Acid DM induced apoptosis with enhanced phosphorylation of glycogen synthase kinase 3 β (GSK3β) via inhibition of the Wnt5/β-catenin pathway. These drugs did not induce apoptosis in normal human neurons. Other events in apoptosis included downregulation of tetraspanin protein (TSPAN12), survival proteins (Bcl-XL and Mcl-1), and overexpression apoptotic factors (Bax and caspase-3). These results provide preliminary strong evidence that medicinal plants containing Limonin, Tangeritin, 6-Gingerol, Zerumbone, Ganoderic Acid A, and Ganoderic Acid DM can be applied to high-grade meningiomas as a therapeutic agent, and suggests that further in vivo studies are necessary to explore its potential as a therapeutic agent against malignant meningiomas.

Background: Chronic diseases drive the burden of disease in many societies, particularly among men. Lifestyle behaviours are strongly associated with chronic disease development, and in a number of countries men tend to engage in more risky behaviours, and have lower health knowledge and attention to prevention, than women. This study investigated the correlates of men's health literacy and its components about major lifestyle-related diseases, namely ischaemic heart disease and type 2 diabetes mellitus, to gain evidence to guide the development of policy and programs to improve men's health., Methods: A systematic review was undertaken of observational studies that investigated men's health literacy and its components related to ischaemic heart disease or type 2 diabetes mellitus, and their associated risk factors. The Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, PsycINFO, Embase and the Cochrane Library databases were searched for articles published since 2003. The strength of the evidence was rated using the GRADE approach., Results: After screening and review of 504 articles, the search elicited nine studies for inclusion: only one study examined health literacy (nutrition literacy). The majority of included studies focused on only one component of health literacy, namely knowledge (n = 7) and personal skills (confidence) (n = 1). Twenty correlates were identified, primarily relating to the knowledge component, with the strength of the evidence for only one correlate, education, graded as being of moderate quality. The evidence for all other correlates was graded as being of low quality., Conclusions: The limited body of research identified may have resulted from a lack of consensus about the definition of health literacy, and a concordant set of validated health literacy measures. Despite these limitations, broadening the search to include components of health literacy has identified that several factors are associated with men's knowledge and awareness of ischaemic heart disease and type 2 diabetes mellitus that will assist in the development of men's health promotion strategies. However, addressing the broader knowledge gaps and controversy in the health literacy field will deliver policy and program benefits to address these major contributors to the burden of disease among men.

Importance: Proteus syndrome is an extremely rare disorder of mosaic postnatal overgrowth affecting multiple tissues including bone, soft tissue, and skin. It typically manifests in early childhood with asymmetric and progressive skeletal overgrowth that leads to severe distortion of the skeleton and disability. The genetic basis has recently been identified as a somatic activating mutation in the AKT1 gene, which encodes an enzyme mediating cell proliferation and apoptosis., Observations: We present a 33-year-old man who developed plantar cerebriform collagenomas on the soles of both feet and varicose veins in early childhood, in the absence of any skeletal or other connective tissue abnormality. Although the patient did not meet the diagnostic criteria for Proteus syndrome, he was found to have the c.49G>A, p.Glu17Lys AKT1 mutation in lesional skin but not in his blood., Conclusions and Relevance: To our knowledge, this is the mildest molecularly confirmed case of Proteus syndrome, occurring in the absence of the characteristic skeletal overgrowth. These findings extend the spectrum of Proteus syndrome pathological characteristics and suggest that somatic mutations late in development and restricted in distribution cause subtle clinical presentations that do not meet the published clinical criteria.

Aim: To identify lifestyle factors associated with healthy aging in middle-aged and older Australian men., Methods: A cross-sectional, population-based, computer-assisted telephone interview study explored self-reported health outcomes, and associated determinants for general and reproductive health (the Men in Australia Telephone Survey) in men aged 40 years and older (n = 5990). "Good health" was defined by self-reported health (excellent/very good) combined with absence of self-reported high blood pressure, heart disease, stroke, diabetes and depression symptoms. Categories of sexual activity frequency in the previous four weeks ranged from zero to 12+ times., Results: "Good health" declined with increasing age with 17% of men over 70 years reporting "good health". In multivariable logistic regression models, significant inverse associations were found between modifiable lifestyle factors - both underweight and overweight/obesity, physical inactivity, smoking and high alcohol consumption - and "good health". Low-risk alcohol intake and living with a partner were positively associated with "good health". Sexual activity was also positively associated with "good health" (p < 0.001) with elevated odds ratios (ORs) for each category of frequency of sexual activity (1-4, 5-8, 9-12 or 12+ times in the past 4 weeks) relative to zero frequency (ORs 1.68 to 2.16)., Conclusion: This study suggests that sexual activity is an important correlate of retaining good health in middle- and older-aged men, independent of other behavioral determinants.

We report the case of a male patient presenting with eosinophilia, pulmonary oedema and eosinophilic fasciitis (EF). He had the classic clinical appearance and magnetic resonance imaging of EF. Cytogenetic analysis of the bone marrow revealed a previously undescribed pericentric inversion of chromosome 5. Overall, the presentation was consistent with a diagnosis of chronic eosinophilic leukaemia, not otherwise specified (CEL-NOS). Dermatologists should consult a haematologist in cases of EF, in order to rule out possible haematological malignancies., (© 2013 British Association of Dermatologists.)

This article evaluates the pilot phase of an Aboriginal and Torres Strait Islander Male Health Module. Although men experience higher levels of illness and die younger than women, educational programs to support health workers utilise a gender-based approach to increase participation of Aboriginal and Torres Strait Islander males in health care are rare and lack appropriate content. Recognising this gap in service provision, and under the guidance of a Reference Group comprising community leaders in Aboriginal and Torres Strait male health, a comprehensive and culturally appropriate Male Health Module has been developed to enhance the capacity of health workers to improve access to services for Aboriginal and Torres Strait Islander males. Methods used were: in-depth interviews with Module developers, pilot workshops for trainers and health workers, questionnaires and focus group discussions with workshop participants, and participant observations. As well as enhancing capacity to facilitate access to health services for men, the Module was deemed relevant because of its potential to promote health worker empowerment and wellbeing. Findings revealed that improving access to services for men required male and female health workers working in partnership. Despite overall enthusiasm for the Module, the findings also revealed deep fear that it would end up 'collecting dust on shelves'. Strategies to improve the Module quality and accessibility are highlighted.

Objective: To explore knowledge about the effects on fertility of age, obesity, smoking, and timing of intercourse among Australians of reproductive age., Design: Telephone survey of a representative sample of Australians., Setting: Not applicable., Patient(s): Australians aged 18 to 45 years who wish to have a child or another child now or in the future., Intervention(s): None., Main Outcome Measure(s): Knowledge about the effect on fertility of age, obesity, smoking, and timing of intercourse., Result(s): A total of 462 interviews were conducted. The majority of respondents underestimated, by about 10 years, the age at which male and female fertility starts to decline. Only one in four correctly identified that female fertility starts to decline before age 35, and one in three identified that male fertility starts to decline before age 45. Most (59%) were aware that female obesity and smoking affect fertility, but fewer recognized that male obesity (30%) and smoking (36%) also influence fertility. Almost 40% of respondents had inadequate knowledge of when in the menstrual cycle a woman is most likely to conceive., Conclusion(s): Considerable knowledge gaps about modifiable factors that affect fertility were identified. These are targeted in a national education campaign to promote awareness of factors that influence fertility., (Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc.

Objective: To better understand help-seeking behaviours and reproductive health disorders among Aboriginal and Torres Strait Islander men., Design, Setting and Participants: A cross-sectional mixed-methods study conducted from 1 May 2004 to 30 April 2005 of 293 Aboriginal and Torres Strait Islander men aged 18 years and over from urban, rural and remote communities in the Northern Territory and Queensland., Main Outcome Measures: Subscale of the International Index of Erectile Function, self-reported help-seeking behaviours for erectile dysfunction (ED) and prostate disease, thematic analysis of semi-structured interviews and focus groups., Results: The prevalence of moderate-to-severe ED increased across age groups, from about 10% in younger men (under 35 years) to 28% in men aged 55-74 years. Moderate-to-severe ED was strongly associated with reporting a chronic condition (odds ratio [OR], 3.67) and residing in a remote area (OR, 2.94). Aboriginal and Torres Strait Islander men aged 40-59 years showed similar low levels of help-seeking behaviours compared with non-Indigenous men from a comparable population-based study. About half of the men with ED saw a doctor or received treatment for ED in each population. While prostate cancer rates were low in both studies, testing for prostate problems was less frequent in Aboriginal and Torres Strait Islander men (11.4%) than in non-Indigenous men (34.1%, P < 0.001), despite similar levels of concern about prostate cancer. Barriers to help-seeking included shame, culturally inappropriate services and lack of awareness., Conclusion: This study, the first to investigate reproductive health of Aboriginal and Torres Strait Islander men, found low levels of help-seeking behaviours for reproductive health disorders, with implications for missing a predictor of chronic disease and late diagnosis of prostate disease.

We report a novel hybrid polyamidoamine (PAMAM) dendrimer hydrogel/poly(lactic-co-glycolic acid) (PLGA) nanoparticle platform (HDNP) for codelivery of two antiglaucoma drugs, brimonidine and timolol maleate. This platform was not cytotoxic to human corneal epithelial cells. Cellular uptake of Nile red-encapsulating PLGA nanoparticles was significantly increased by dendrimer hydrogel. A prolonged residence time of nanoparticles was demonstrated through investigation of FluoSpheres loaded into dendrimer hydrogel. Both brimonidine and timolol maleate were slowly released in vitro over a period of 28-35 days. Following topical administration of one eye drop (30 μL of 0.7% w/v brimonidine and 3.5% w/v timolol maleate) in normotensive adult Dutch-belted male rabbits, the HDNP formulation resulted in a sustained and effective IOP reduction (18% or higher) for 4 days. Furthermore, the HDNP maintained significantly higher concentrations of brimonidine in aqueous humor and cornea as well as timolol maleate in the aqueous humor, cornea, and conjunctiva up to 7 days as compared to saline, DH, and PLGA nanoparticle dosage forms, without inducing ocular inflammation or discomfort. Histological analysis of the cornea and conjunctiva did not reveal any morphological or structural changes. Our work demonstrated that this new platform is capable of enhancing drug bioavailability and sustaining effective IOP reduction over an extended period of time. This newly developed platform can greatly reduce dosing frequency of topical formulations, thus, improving long-term patient compliance and reducing enormous societal and economic costs. Given its high structural adaptability, many other chronic ocular diseases would benefit from long-lasting drug delivery of this new platform.

Dendrimer hydrogel (DH), made from ultraviolet-cured polyamidoamine dendrimer G3.0 tethered with three polyethylene glycol (PEG, 12,000 Da)-acrylate chains (8.1% w/v) in pH 7.4 phosphate buffered saline (PBS), was studied for the delivery of brimonidine (0.1% w/v) and timolol maleate (0.5% w/v), two antiglaucoma drugs. DH was found to be mucoadhesive to mucin particles and nontoxic to human corneal epithelial cells. DH increased the PBS solubility of brimonidine by 77.6% and sustained the in vitro release of both drugs over 56-72 hours. As compared to eye drop formulations (PBS-drug solutions), DH brought about substantially higher human corneal epithelial cells uptake and significantly increased bovine corneal transport for both drugs. DH increased timolol maleate uptake in bovine corneal epithelium, stroma, and endothelium by 0.4- to 4.6-fold. This work demonstrated that DH can enhance the delivery of antiglaucoma drugs in multiple aspects and represents a novel platform for ocular drug delivery., From the Clinical Editor: Dendrimer hydrogel was studied as agent for simultaneous delivery of two anti-glaucoma drugs, one hydrophobic and one hydrophilic. Superiority over standard PBS-based formulation was clearly demonstrated for both drugs. The work may be a novel platform for ocular drug delivery., (Copyright © 2012 Elsevier Inc.

While focussing on influential actors within a policy network may provide insight into the shaping of policy, it fails to elucidate how the network itself may moderate the behaviours of actors when participating in the policy process. Applying Skok's (1995) structural-functional framework, this study explores whether network analysis provides an alternative analytical approach to explain how the broader structural features of the network may influence actors participating in different functional phases of the policy cycle. To illustrate the rationale for a network analysis approach to policy analysis, we introduce the 2010 Australian National Male Health Policy, as an illustrative case of a network of competing interests within the broader health policy domain. An analysis of the associated men's health network and the network structures that exist for different relational purposes identified a weak (low density) network, which lacked a hierarchical structure, and where levels of reciprocity between actors was low. Network characteristics changed depending on the relationship type between actors, highlighting the dynamic nature of networks and reflecting the different imperatives of the policy process. An understanding of network structures gained from the network analysis approach described in this study potentially provides policy-makers, and stakeholders, with an alternative tool to stakeholder analysis when considering engagement with the policy process., (Copyright © 2011 Elsevier Ltd.

Background: The relationship between reproductive health disorders and lifestyle factors in middle-aged and older men is not clear. The aim of this study is to describe lifestyle and biomedical associations as possible causes of erectile dysfunction (ED), prostate disease (PD), lower urinary tract symptoms (LUTS) and perceived symptoms of androgen deficiency (pAD) in a representative population of middle-aged and older men, using the Men in Australia Telephone Survey (MATeS)., Methods: A representative sample (n = 5990) of men aged 40+ years, stratified by age and State, was contacted by random selection of households, with an individual response rate of 78%. All men participated in a 20-minute computer-assisted telephone interview exploring general and reproductive health. Associations between male reproductive health disorders and lifestyle and biomedical factors were analysed using multivariate logistic regression (odds ratio [95% confidence interval]). Variables studied included age, body mass index, waist circumference, smoking, alcohol consumption, physical activity, co-morbid disease and medication use for hypertension, high cholesterol and symptoms of depression., Results: Controlling for age and a range of lifestyle and co-morbid exposures, sedentary lifestyle and being underweight was associated with an increased likelihood of ED (1.4 [1.1-1.8]; 2.9 [1.5-5.8], respectively) and pAD (1.3 [1.1-1.7]; 2.7 [1.4-5.0], respectively. Diabetes and cardiovascular disease were both associated with ED, with hypertension strongly associated with LUTS and pAD. Current smoking (inverse association) and depressive symptomatology were the only variables independently associated with PD. All reproductive disorders showed consistent associations with depression (measured either by depressive symptomatology or medication use) in both age-adjusted and multivariate analyses., Conclusion: A range of lifestyle factors, more often associated with chronic disease, were significantly associated with male reproductive health disorders. Education strategies directed to improving general health may also confer benefits to male reproductive health.

Tumors frequently contain hypoxic regions that result from a shortage of oxygen due to poorly organized tumor vasculature. Cancer cells in these areas are resistant to radiation- and chemotherapy, limiting the treatment efficacy. Macrophages have inherent hypoxia-targeting ability and hold great advantages for targeted delivery of anticancer therapeutics to cancer cells in hypoxic areas. However, most anticancer drugs cannot be directly loaded into macrophages because of their toxicity. In this work, we designed a novel drug delivery vehicle by hybridizing macrophages with nanoparticles through cell surface modification. Nanoparticles immobilized on the cell surface provide numerous new sites for anticancer drug loading, hence potentially minimizing the toxic effect of anticancer drugs on the viability and hypoxia-targeting ability of the macrophage vehicles. In particular, quantum dots and 5-(aminoacetamido) fluorescein-labeled polyamidoamine dendrimer G4.5, both of which were coated with amine-derivatized polyethylene glycol, were immobilized to the sodium periodate-treated surface of RAW264.7 macrophages through a transient Schiff base linkage. Further, a reducing agent, sodium cyanoborohydride, was applied to reduce Schiff bases to stable secondary amine linkages. The distribution of nanoparticles on the cell surface was confirmed by fluorescence imaging, and it was found to be dependent on the stability of the linkages coupling nanoparticles to the cell surface.

It is generally agreed that general practices tend to be 'female oriented'. As part of a strategy to reduce barriers for men accessing health care, the Australian Government's proposed National Men's Health Policy has stated that a focus on 'male friendly' settings will be adopted.

Dermatomyositis (DM) is an idiopathic inflammatory myopathy associated with characteristic cutaneous features. Panniculitis is a rarely reported clinical finding in this condition. This report describes two cases of adult-onset DM complicated by severe calcific panniculitis. In both cases, the associated pain and loss of function seemed to be best managed on combination anti-malarial therapy with mepacrine and hydroxychloroquine.
