The effect of a financial incentive on COVID-19 vaccination uptake, and predictors of uptake, in people experiencing homelessness: A randomized controlled trial.

People who are homeless are at increased risk of COVID-19 infection, and of poorer associated outcomes. Delivering vaccinations to, and ensuring uptake of multiple doses in, people who are homeless is complex. Financial incentives may improve vaccination uptake, particularly in people who have not received routine vaccinations previously, though evidence about the effect of incentives is limited and variable. This randomized controlled trial (ANZCTR 383156) assessed the effect of a financial incentive (an A$10 grocery voucher) on uptake of the second COVID-19 vaccination in Australian adults who were homeless, and who had received their first dose. Participants were recruited through a vaccination program for people experiencing homelessness between September 2021 and January 2022. They were followed-up for a minimum of 6.5 months. Uptake was measured 'on-time' at 6 weeks, and at any time during the trial period. Vaccination status was checked on the Australian Immunisation Register. Demographic and vaccination program characteristics associated with uptake were also investigated. Eighty-six people consented to participate, and 43 were randomly allocated to each of the 'incentive' and 'no incentive' groups. The incentive slightly increased the likelihood of a participant receiving a second vaccination on-time (risk difference (RD), 11.6 % [95 %CI, -9.0, 32.2 %]; p = 0.27), and at any time during the trial (RD, 14.0 % [95 %CI, -2.2, 30.1 %], p = 0.09). The incentive had a significant positive effect on uptake in people with no previous vaccination history, increasing their likelihood of receiving a second vaccination on-time (RD, 42.3 % [95 %CI, 15.7, 68.8 %]; p = 0.002) and at any time during the trial (RD, 38.7 % [95 %CI, 16.1, 61.3 %], p < 0.001). Financial incentives may increase COVID-19 vaccination uptake in people who are homeless, and particularly those who have no previous vaccination history. Future research should consider alternative incentive values, types, and cost-effectiveness.

The Australian Reproductive Genetic Carrier Screening Project (Mackenzie's Mission): Design and Implementation.

Reproductive genetic carrier screening (RGCS) provides people with information about their chance of having children with autosomal recessive or X-linked genetic conditions, enabling informed reproductive decision-making. RGCS is recommended to be offered to all couples during preconception or in early pregnancy. However, cost and a lack of awareness may prevent access. To address this, the Australian Government funded Mackenzie's Mission­the Australian Reproductive Genetic Carrier Screening Project. Mackenzie's Mission aims to assess the acceptability and feasibility of an easily accessible RGCS program, provided free of charge to the participant. In study Phase 1, implementation needs were mapped, and key study elements were developed. In Phase 2, RGCS is being offered by healthcare providers educated by the study team. Reproductive couples who provide consent are screened for over 1200 genes associated with >750 serious, childhood-onset genetic conditions. Those with an increased chance result are provided comprehensive genetic counseling support. Reproductive couples, recruiting healthcare providers, and study team members are also invited to complete surveys and/or interviews. In Phase 3, a mixed-methods analysis will be undertaken to assess the program outcomes, psychosocial implications and implementation considerations alongside an ongoing bioethical analysis and a health economic evaluation. Findings will inform the implementation of an ethically robust RGCS program.

Impacts of the COVID-19 pandemic, and of government responses to the pandemic, on people who are homeless in Australia: Mapping perceptions of a national sample of homelessness service workers.

People who are homeless are disproportionately impacted by the COVID-19 pandemic, and by government responses to the pandemic. This study maps the perceptions of homelessness service workers in Australia, about the impacts of the COVID-19 pandemic and government responses to it on people who are homeless. An electronic survey was distributed to homelessness service across Australia in June/July 2020, following Australia's 'first wave' of COVID-19. Fifty-nine homelessness services from all eight states/territories responded. Perceptions of impacts on people who are homeless were mapped in six themes: (1) changes in the types of people presenting, (2) overall impacts on peoples' lives, (3) impacts on mental health, (4) impacts of changes in service delivery, (5) impacts of government support and (6) ongoing impacts. The COVID-19 pandemic, and government responses to the pandemic, have affected every aspect of the lives of people who are homeless in Australia. There is a continuing need to support people who are homeless as the world transitions to the 'new normal' of COVID-19, particularly as rates of homelessness increase. Understanding impacts is vital to informing relevant and effective health, social and other supports for this group.

Strategies to improve vaccination rates in people who are homeless: A systematic review.

People who are homeless experience higher rates of vaccine-preventable disease, including COVID-19, than the general population, and poorer associated health outcomes. However, delivering vaccinations to people who are homeless is complex, and there is a lack of evidence to inform practice in this area. The aim of this systematic review is to: (a) identify, (b) analyse the characteristics of, and (c) evaluate the outcomes of, strategies to improve vaccination rates in people who are homeless. Literature was retrieved from eight electronic databases. Studies undertaken in high-income countries, published in English, in a peer-reviewed journal, and in full-text were considered. No limits were placed on study design or date. A total of 1,508 articles were retrieved and, after the removal of duplicates, 637 were screened. Twenty-three articles, reporting on nineteen separate vaccination strategies for hepatitis A/B, influenza, herpes zoster, invasive pneumococcal disease, and diphtheria in people who are homeless, were selected for inclusion. All the strategies were effective at improving vaccination rates in, people who are homeless. Most strategies involved vaccination clinics and most were delivered, at least in part, by nurses. Other characteristics of successful strategies included: delivering vaccinations at convenient locations; using accelerated vaccination schedules (if available); vaccinating at the first appointment, regardless of whether a person's vaccination history or serological status were known (if clinically safe); operating for a longer duration; offering training to staff about working with people who are homeless; widely promoting clinics; considering education, reminders, incentives, and co-interventions; ensuring no out-of-pocket costs; and working collaboratively with stakeholders, including people who are homeless themselves. These findings will inform evidence-based vaccination strategies, including for COVID-19, in people who are homeless, and improve associated health outcomes in this at-risk, hard-to-reach group.

A comprehensive review of economic evaluations of therapeutic drug monitoring interventions for cancer treatments.

Therapeutic drug monitoring (TDM) of cancer drugs has been shown to improve treatment effectiveness and safety. The aim of this paper was to comprehensively review economic evaluations of TDM interventions for cancer drugs. Searches were conducted in 4 electronic databases, Medline, EMBASE, and Centre for Reviews and Dissemination databases (Database of Abstracts of Reviews of Effects and the NHS Economic Evaluation Database), from their inception to June 2019. Studies were included if they were economic evaluations of TDM interventions for an active cancer treatment. The quality of reporting of economic evaluations was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS checklist). Of the 11 publications identified, imatinib with TDM and 5-fluorouracil with TDM were the most commonly assessed interventions (4 publications each). Overall study quality was good, with publications meeting 61 to 91% (median 80%) of CHEERS checklist criteria. A variety of studies were used to estimate the clinical effectiveness inputs for the cost effectiveness models. All publications considered TDM to be cost-effective based on an incremental cost-effectiveness ratio below the willingness to pay threshold (64%) or being cost-saving (36%). TDM interventions were considered cost-effective across the economic evaluations. Further clinical research assessing the impact of TDM on overall survival or other long-term health outcomes may enhance the evidence base for TDM in oncology. Future economic evaluations of TDM should explicitly consider uncertainty in the underlying clinical evidence and incorporate changes in the use of newer targeted drugs that form the current standard of care.

Use of clinical vignette questionnaires to investigate the variation in management of keratoconjunctivitis sicca and acute glaucoma in dogs.

There is little peer-reviewed research assessing therapeutic effectiveness in canine eye disease. Current treatments used in first opinion and ophthalmology referral practices are also somewhat poorly documented. The aim of this study was to investigate the current management of canine keratoconjunctivitis sicca (KCS) and acute primary angle-closure glaucoma (PACG) by veterinary surgeons. Questionnaires using clinical vignettes were administered to a cross section of general practitioners ('GPs') and veterinarians engaged in or training for postgraduate ophthalmology practice ('PGs'). Similar treatment recommendations for KCS (topical cyclosporine, lubricant, antibiotic) were given by both groups of veterinarians with the single exception of increased topical antibiotic use by GPs. Treatment of acute glaucoma diverged between groups: PGs were much more likely to recommend topical prostaglandin analogues and a wider array of both topical and systemic treatments were recommended by both groups. Systemic ocular hypotensive agents were suggested infrequently. Our results suggest that treatments may vary substantially in ocular conditions, particularly in conditions for which neither guidelines nor high-quality evidence exists. This study highlights the need for novel strategies to address evidence gaps in veterinary medicine, as well as for better evaluation and dissemination of current treatment experience.

The cost-effectiveness of oral health interventions: A systematic review of cost-utility analyses.

OBJECTIVES: To assess the usage of cost-utility analysis (CUA) in oral health interventions and to evaluate the methods used and the reporting quality of CUA in publications on oral health interventions. METHODS: A systematic review was performed on literature published between 2000 and 2016 where cost-utility analyses of oral health interventions were included. The reporting quality of these oral health CUAs was assessed against the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. RESULTS: Of the 6637 publications identified initially, 23 met the inclusion criteria. Of these, 14 (61%) had been published in the last 6 years. Included studies were on oral cancer (n = 6), provision of dental prosthesis (n = 6), dental caries (n = 4), periodontal diseases (n = 3), antibiotic prophylaxis (n = 2), dento-facial anomalies (n = 1) and dental service provision (n = 1). Twenty-one studies were able to identify the most cost-effective intervention among the different options compared. Of the 23 studies identified, 15 (65%) used quality-adjusted life years (QALY) as the outcome measure, and 18 (78%) reported an incremental cost-effectiveness ratio. The economic perspective was clearly stated in 13 articles (57%). Twenty studies (87%) reported the discount rate, and 22 (96%) undertook sensitivity analysis. The reporting quality of studies, appraised by the CHEERS checklist, varied from 75% to 100% (median 92%). CONCLUSION: The use of CUAs in evaluation of oral health interventions has been increasing recently, especially from 2011 to 2016. The majority of CUA articles were of good reporting quality as assessed by the CHEERS checklist and were able to provide conclusions regarding the most cost-effective intervention among the different options compared: this will assist in healthcare decision-making and resource allocation. These positive outcomes of our study encourage wider use of CUAs within the dental and oral health professions.

Understanding the context for pet cat and dog feeding and exercising behaviour among pet owners in Ireland: a qualitative study.

BACKGROUND: Pet cat and dog obesity contributes to increased risk of several diseases, including cancer and diabetes mellitus as well as a worsening of orthopaedic problems, and a reduction in survival rate. This study aims to develop a better understanding of cat and dog owners' self-reported beliefs and factors that influence owner behaviour around feeding and exercising their pet cat or dog, as there is a lack of in-depth understanding in this area. Seven focus group discussions, with 43 pet owners in total, were conducted. RESULTS: Pet owners often reported a perceived a low level of control over feeding; often undermined by other people feeding of their pet, their pets begging for food, and their pets attitude towards food. Treats were used in the absence of owner control over pet begging and emotional attachment, and to influence pet behaviour. The majority of participants had positive attitudes to pet exercise, which could be related to pet specific requirements, especially differences in cats and dogs. There were some negative experiences of stress associated with dog walking and fears over aggressive confrontations with other dogs. CONCLUSION: Feeding one's pet is influenced by beliefs about pet specific needs, pet food and pet health, pet owners' perceived control over feeding, and the implications for the pet owner. Pet exercise is influenced by beliefs about pet specific exercise needs, and the implications of exercising one's pet for the pet owner. Understanding owner behaviours on feeding and exercise allows for a more targeted approach to preventing and treating pet obesity.

Telephone consultations for general practice: a systematic review.

BACKGROUND: The use of information technology, including internet- and telephone-based resources, is becoming an alternative and supporting method of providing many forms of services in a healthcare and health management setting. Telephone consultations provide a promising alternative and supporting service for face-to-face general practice care. The aim of this review is to utilize a systematic review to collate evidence on the use of telephone consultation as an alternative to face-to-face general practice visits. METHODS: A systematic search of MEDLINE, CINAHL, The Cochrane Library, and the International Clinical Trials Registry Platform was performed using the search terms for the intervention (telephone consultation) and the comparator (general practice). Systematic reviews and randomized control trials that examined telephone consultation compared to normal face-to-face consultation in general practice were included in this review. Papers were reviewed, assessed for quality (Cochrane Collaboration's 'Risk of bias' tool) and data extracted and analysed. RESULTS: Two systematic reviews and one RCT were identified and included in the analysis. The RCT (N = 388) was of patients requesting same-day appointments from two general practices and patients were randomized to a same-day face-to-face appointment or a telephone call back consultation. There was a reduction in the time spent on consultations in the telephone group (1.5 min (0.6 to 2.4)) and patients in the telephone arm had 0.2 (0 to 0.3) more follow-up consultations than the face-to-face group. One systematic review focused on telephone consultation and triage on healthcare use, and included one RCT and one other observational study that examined telephone consultations. The other systematic review focused on patient access and included one RCT and four observational studies that examined telephone consultations. Both systematic reviews provided narrative interpretations of the evidence and concluded that telephone consultations provided an appropriate alternative to telephone consultations and reduced practice work load. CONCLUSION: There is a lack of high level evidence for telephone consultations in a GP setting; however, current evidence suggests that telephone consultations as an alternative to face-to-face general practice consultations offers an appropriate option in certain settings.

Cost-effectiveness of dual-energy X-ray absorptiometry plus antiresorptive treatment in Australian women with breast cancer who receive aromatase inhibitors.

Postmenopausal women with breast cancer on aromatase inhibitor (AI) treatment are at increased risk of bone mineral density loss, which may lead to minimal trauma fractures. We examined the cost-effectiveness of dual energy X-ray absorptiometry (DXA) with antiresorptive (AR) therapy compared with fracture risk assessment, lifestyle advice, and vitamin supplementation. We used a hypothetical Markov cohort model of lifetime duration for 60-year-old women with early stage breast cancer receiving AIs. The data to inform the model came from medical literature, epidemiological reports, and costing data sets. Two eligibility scenarios for AR therapy were considered: (A) osteoporosis and (B) osteopenia or osteoporosis. The main outcomes were incremental cost per quality-adjusted life years gained and cumulative fractures per 1000 women, calculated relative to the comparator. Key aspects of the model were explored in sensitivity analyses. Due to relatively low effectiveness gains, the outcomes were primarily driven by the costs. The incremental cost per quality-adjusted life year gained was A$47,556 and A$253,000 for scenarios A and B, respectively. The numbers of fractures avoided were 56 and 77 per 1000 women, respectively. The results were most sensitive to the initial probability of osteoporosis, baseline risk of fracture, and cohort starting age. Compared with risk assessment and lifestyle advice only, a DXA scan followed by an AR treatment is potentially cost-effective for women aged 60 and over undergoing AI therapy for early breast cancer. However, the number of fractures averted through this intervention is small.

Development of a critical appraisal tool to assess the quality of cross-sectional studies (AXIS).

OBJECTIVES: The aim of this study was to develop a critical appraisal (CA) tool that addressed study design and reporting quality as well as the risk of bias in cross-sectional studies (CSSs). In addition, the aim was to produce a help document to guide the non-expert user through the tool. DESIGN: An initial scoping review of the published literature and key epidemiological texts was undertaken prior to the formation of a Delphi panel to establish key components for a CA tool for CSSs. A consensus of 80% was required from the Delphi panel for any component to be included in the final tool. RESULTS: An initial list of 39 components was identified through examination of existing resources. An international Delphi panel of 18 medical and veterinary experts was established. After 3 rounds of the Delphi process, the Appraisal tool for Cross-Sectional Studies (AXIS tool) was developed by consensus and consisted of 20 components. A detailed explanatory document was also developed with the tool, giving expanded explanation of each question and providing simple interpretations and examples of the epidemiological concepts being examined in each question to aid non-expert users. CONCLUSIONS: CA of the literature is a vital step in evidence synthesis and therefore evidence-based decision-making in a number of different disciplines. The AXIS tool is therefore unique and was developed in a way that it can be used across disciplines to aid the inclusion of CSSs in systematic reviews, guidelines and clinical decision-making.

Evidence for Using Farm Care Practices to Improve Attachment Outcomes in Foster Children: A Systematic Review.

Anecdotal evidence suggests that care farming practices have the potential to provide positive outcomes for young people in foster-care and residential care environments. A systematic review (searching; CINAHL, Web of Knowledge, PsychInfo) was conducted to explore how participation in care farming initiatives impacts attachment in children in foster-care and what aspects of care farming initiatives provides positive attachment outcomes. The systematic review did not identify any research publication in care farming and foster-care. Therefore, it is imperative that practitioners realise that the evidence is lacking when using these types of interventions and keep a close account of the benefit and harms that may be encountered during the interaction processes.

Triple therapy in type 2 diabetes; a systematic review and network meta-analysis.

Aims. The purpose was to evaluate the evidence for triple therapy regimen using medicines available in Australia for type 2 diabetes. Methods. A systematic literature review was performed to update the relevant evidence from 2002 to 2014 on triple therapy for type 2 diabetes. A multiple-treatments network meta-analysis was undertaken to summarise the comparative efficacy and harms of different triple therapies. Results. Twenty seven trials were identified, most were six months of duration. The following combinations were included in the network meta-analysis: metformin (MET) + sulfonylureas (SU) (used as reference combination); MET + SU+ dipeptidyl peptidase 4 inhibitors (DPP-4-i); MET + SU+ thiazolidinediones (TZD); MET + SU+ glucagon-like peptide-1 receptor agonists (GLP-1-RA); MET + SU+ insulins; MET + TZD + DPP-4-i; and MET + SU+ sodium/glucose cotransporter 2 inhibitors (SGLT2-i). For HbA1c reduction, all triple therapies were statistically superior to MET+SU dual therapy, except for MET + TZD + DPP-4-i. None of the triple therapy combinations demonstrated differences in HbA1c compared with other triple therapies. MET + SU + SGLT2-i and MET + SU + GLP-1-RA resulted in significantly lower body weight than MET + SU + DPP-4-i, MET+SU+insulin and MET + SU + TZDs; MET + SU + DPP-4-i resulted in significantly lower body weight than MET + SU + insulin and MET + SU + TZD. MET + SU + insulin, MET + SU + TZD and MET + SU + DPP-4-i increased the odds of hypoglycaemia when compared to MET + SU. MET + SU + GLP-1-RA reduced the odds of hypoglycaemia compared to MET + SU + insulin. Conclusion. Care when choosing a triple therapy combination is needed as there is often a risk of increased hypoglycaemia events associated with this regimen and there are very limited data surrounding the long-term effectiveness and safety of combined therapies.

Telemedicine for general practice: a systematic review protocol.

BACKGROUND: The use of information technology in healthcare is fast becoming an alternative and supporting method of providing many forms of services in a healthcare and health management setting. Telephone technology is used readily to deliver services such as disease management, consultations and behaviour coaching. Telemedicine provides a promising alternative and supporting service for face-to-face general practice care. The aim of this review is to utilise a systematic review to collate evidence on the use of telemedicine as a lead in and an alternative to general practice visits. METHODS/DESIGN: A systematic search of MEDLINE, CINAHL, the Cochrane Library and the International Clinical Trials Registry Platform will be performed using the search terms for the intervention (telemedicine) and the comparator (general practice) to search the databases. The systematic review aims to identify randomised control trials; however, if none are identified, an updated search will be conducted to identify lower levels of evidence. Papers will be reviewed and assessed for quality and data extracted using two reviewers; if consensus is required, a third reviewer will be consulted. If applicable, a meta-analysis of relevant outcomes will be conducted. The protocol has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocols (PRISMA-P) guidelines. DISCUSSION: The intervention and comparator have the potential to provide a vast range of healthcare services to a range of diseases and health conditions. There is likely to be difficulty in identifying relevant clinical outcome measures for the patient population. A range of outcome measures will therefore be collected in the data extraction phase. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015025225.

Neutering of cats and dogs in Ireland; pet owner self-reported perceptions of enabling and disabling factors in the decision to neuter.

Background. Failure among pet owners to neuter their pets results in increased straying and overpopulation problems. Variations in neutering levels can be explained by cultural differences, differences in economic status in rural and urban locations, and owner perceptions about their pet. There are also differences between male and female pet owners. There is no research pertaining to Irish pet owner attitudes towards neutering their pets. This paper identified the perceptions of a sample of Irish cat and dog owners that influenced their decisions on pet neutering. Methods. This study was conducted using social science (qualitative) methods, including an interview-administered survey questionnaire and focus group discussions. Data was coded and managed using Nvivo 8 qualitative data analysis software. Results. Focus groups were conducted with 43 pet (cats and dogs) owners. Two major categories relating to the decision to neuter were identified: (1) enabling perceptions in the decision to neuter (subcategories were: controlling unwanted pet behaviour; positive perceptions regarding pet health and welfare outcomes; perceived owner responsibility; pet function; and the influence of veterinary advice), and (2) disabling perceptions in the decision to neuter (subcategories were: perceived financial cost of neutering; perceived adequacy of existing controls; and negative perceptions regarding pet health and welfare outcomes). Discussion. Pet owner sense of responsibility and control are two central issues to the decision to neuter their pets. Understanding how pet owners feel about topics such as pet neutering, can help improve initiatives aimed at emphasising the responsibility of population control of cats and dogs.

Methods used to estimate the size of the owned cat and dog population: a systematic review.

BACKGROUND: There are a number of different methods that can be used when estimating the size of the owned cat and dog population in a region, leading to varying population estimates. The aim of this study was to conduct a systematic review to evaluate the methods that have been used for estimating the sizes of owned cat and dog populations and to assess the biases associated with those methods.A comprehensive, systematic search of seven electronic bibliographic databases and the Google search engine was carried out using a range of different search terms for cats, dogs and population. The inclusion criteria were that the studies had involved owned or pet domestic dogs and/or cats, provided an estimate of the size of the owned dog or cat population, collected raw data on dog and cat ownership, and analysed primary data. Data relating to study methodology were extracted and assessed for biases. RESULTS: Seven papers were included in the final analysis. Collection methods used to select participants in the included studies were: mailed surveys using a commercial list of contacts, door to door surveys, random digit dialled telephone surveys, and randomised telephone surveys using a commercial list of numbers. Analytical and statistical methods used to estimate the pet population size were: mean number of dogs/cats per household multiplied by the number of households in an area, human density multiplied by number of dogs per human, and calculations using predictors of pet ownership. CONCLUSION: The main biases of the studies included selection bias, non-response bias, measurement bias and biases associated with length of sampling time. Careful design and planning of studies is a necessity before executing a study to estimate pet populations.

The spatial distribution of pet dogs and pet cats on the island of Ireland.

BACKGROUND: There is considerable international research regarding the link between human demographics and pet ownership. In several international studies, pet ownership was associated with household demographics including: the presence of children in the household, urban/rural location, level of education and age/family structure. What is lacking across all these studies, however, is an understanding of how these pets are spatially distributed throughout the regions under study. This paper describes the spatial distribution of pet dog and pet cat owning households on the island of Ireland. RESULTS: In 2006, there were an estimated 640,620 pet dog owning households and 215,542 pet cat owning households in Ireland. These estimates are derived from logistic regression modelling, based on household composition to determine pet dog ownership and the type of house to determine pet cat ownership. Results are presented using chloropleth maps. There is a higher density of pet dog owning households in the east of Ireland and in the cities than the west of Ireland and rural areas. However, in urban districts there are a lower proportion of households owning pet dogs than in rural districts. There are more households with cats in the urban areas, but the proportion of households with cats is greater in rural areas. CONCLUSIONS: The difference in spatial distribution of dog ownership is a reflection of a generally higher density of households in the east of Ireland and in major cities. The higher proportion of ownership in the west is understandable given the higher proportion of farmers and rural dwellings in this area. Spatial representation allows us to visualise the impact of human household distribution on the density of both pet dogs and pet cats on the island of Ireland. This information can be used when analysing risk of disease spread, for market research and for instigating veterinary care.

Comprehensive environmental management of asthma and pediatric preventive care.

Indoor environmental triggers can increase asthma morbidity. National guidelines recommend comprehensive use of environmental control practices (ECPs) as a component of asthma management. The purpose of this study was to examine the association between preventive asthma care and comprehensive ECP use among children with asthma. We used data from the National Asthma Survey, including 1,921 children with asthma. Comprehensive use was defined as using at least five of eight ECPs: (i) air filter, (ii) dehumidifier, (iii) mattress cover, (iv) pillow cover, (v) pet avoidance, (vi) smoke avoidance, (vii) removing carpets, and (viii) washing sheets in hot water. Univariate and multiple regression analyses were conducted to examine the association between comprehensive use of ECPs and receipt of preventive asthma care, as measured by number of routine asthma visits in the prior year and physician advice to modify the environment. Overall, 17% (95% CI: 14-19%) of participants had comprehensive ECP use. The most commonly used practices were 'smoke avoidance' (85%), 'pet avoidance' (59%), and 'washing sheets in hot water' (46%). Comprehensive use of ECPs was associated with having received physician advice [odds ratio (OR) 3.1, 95% CI: 2.2-4.4] and increased asthma visits (1-2 visits: OR 1.5, 95% CI: 1.0-2.4; 3-4 visits: OR 2.2, 95% CI: 1.3-3.8; ≥5 visits: OR 2.7, 95% CI: 1.5-4.8). Only a minority of parents implement comprehensive ECPs, and receipt of preventive asthma care is associated with comprehensive use. Further research is needed to determine the factors mediating these associations in order to inform more effective asthma counseling.

Role of androgen receptor and associated lysine-demethylase coregulators, LSD1 and JMJD2A, in localized and advanced human bladder cancer.

Bladder cancer is approximately three times more common in men as compared to women. We and others have previously investigated the contribution of androgens and the androgen receptor (AR) to bladder cancer. JMJD2A and LSD1 are recently discovered AR coregulator proteins that mediate AR-dependent transcription via recently described histone lysine-demethylation (KDM) mechanisms. We used immunohistochemistry to examine JMJD2A, LSD1, and AR expression in 72 radical cystectomy specimens, resulting in evaluation of 129 tissue samples (59 urothelial carcinoma, 70 benign). We tested levels of these proteins for statistical association with clinicopathologic variables and patient survival. Expression of these markers was also assessed in human bladder cancer cell lines. The effects of pharmacological inhibition of LSD1 on the proliferation of these bladder cancer cells was determined. JMJD2A and AR levels were significantly lower in malignant versus benign urothelium, while increased LSD1 levels were observed in malignant urothelium relative to benign. A significant reduction in all three proteins occurred with cancer stage progression, including muscle invasion (JMJD2A/LSD1/AR), extravesical extension (JMJD2A/LSD1), and lymph node metastasis (JMJD2A/AR). Lower JMJD2A intensity correlated with additional poor prognostic features, including lymphovascular invasion, concomitant carcinoma in situ and tobacco usage, and predicted significantly worse overall survival. Pharmacological inhibition of LSD1 suppressed bladder cancer cell proliferation and androgen-induced transcription. Our results support a novel role for the AR-KDM complex in bladder cancer initiation and progression, identify JMJD2A as a promising prognostic biomarker, and demonstrate targeting of the KDM activity as an effective potential approach for bladder cancer growth inhibition.

Factors associated with furry pet ownership among patients with asthma.

BACKGROUND: Exposure to indoor allergens is an established risk factor for poor asthma control. Current guidelines recommend removing pets from the home of patients with asthma. OBJECTIVES: This cross-sectional study was conducted to determine the prevalence of furry pet ownership in asthmatics compared to non-asthmatics and to identify factors associated with furry pet ownership among those with asthma. Secondary analysis assessed characteristics among asthmatics that might be associated with allowing a furry pet into the bedroom. METHODS: Using data from The National Asthma Survey collected from 2003 to 2004, we carried out univariate and multiple regression analyses, in 2009, to identify independent predictors of furry pet ownership in asthma sufferers after controlling for potential confounders. RESULTS: Overall, asthmatics were more likely to own a furry pet than nonasthmatic individuals in the general population (49.9% versus 44.8%, p < .001). Multivariate analysis showed that female sex, older age, white race, and high income were independent predictors of furry pet ownership among asthmatics. Additionally, 68.7% of patients with asthma who own a furry pet allowed them into their bedroom. Higher income and carrying out < or =2 environmental control practices in the home were associated with increased likelihood of allowing a furry pet into the bedroom. CONCLUSIONS: Furry pet ownership is equally or more common among asthmatics compared to those without asthma. The majority of asthmatics with furry pets allow them into the bedroom. Recognizing and addressing these problems may help decrease asthma morbidity.
