RESUMO

BACKGROUND: Adaptive radiations are characterized by extreme and/or iterative phenotypic divergence; however, such variation does not accumulate evenly across an organism. Instead, it is often partitioned into sub-units, or modules, which can differentially respond to selection. While it is recognized that changing the pattern of modularity or the strength of covariation (integration) can influence the range or rate of morphological evolution, the relationship between shape variation and covariation remains unclear. For example, it is possible that rapid phenotypic change requires concomitant changes to the underlying covariance structure. Alternatively, repeated shifts between phenotypic states may be facilitated by a conserved covariance structure. Distinguishing between these scenarios will contribute to a better understanding of the factors that shape biodiversity. Here, we explore these questions using a diverse Lake Malawi cichlid species complex, Tropheops, that appears to partition habitat by depth. RESULTS: We construct a phylogeny of Tropheops populations and use 3D geometric morphometrics to assess the shape of four bones involved in feeding (mandible, pharyngeal jaw, maxilla, pre-maxilla) in populations that inhabit deep versus shallow habitats. We next test numerous modularity hypotheses to understand whether fish at different depths are characterized by conserved or divergent patterns of modularity. We further examine rates of morphological evolution and disparity between habitats and among modules. Finally, we raise a single Tropheops species in environments mimicking deep or shallow habitats to discover whether plasticity can replicate the pattern of morphology, disparity, or modularity observed in natural populations. CONCLUSIONS: Our data support the hypothesis that conserved patterns of modularity permit the evolution of divergent morphologies and may facilitate the repeated transitions between habitats. In addition, we find the lab-reared populations replicate many trends in the natural populations, which suggests that plasticity may be an important force in initiating depth transitions, priming the feeding apparatus for evolutionary change.

RESUMO

BACKGROUND: Primary care may be an avenue to increase coverage of HIV testing but it is unclear what challenges primary healthcare professionals in low- and middle-income countries face. We describe the HIV testing practices in community health centres (CHCs) and explore the staff's attitude towards further development of HIV testing services at the primary care level in China. METHODS: We conducted a national, cross-sectional survey using a stratified random sample of CHCs in 20 cities in 2015. Questionnaires were completed by primary care doctors and nurses in CHCs, and included questions regarding their demographics, clinical experience and their views on the facilitators and barriers to offering HIV testing in their CHC. Multivariate logistic regression was conducted to examine the association between staff who would offer HIV testing and their sociodemographic characteristics. RESULTS: A total of 3580 staff from 158 CHCs participated. Despite the majority (81%) agreeing that HIV testing was an important part of healthcare, only 25% would provide HIV testing when requested by a patient. The majority (71%) were concerned about reimbursement, and half (47%) cited lack of training as a major barrier. Almost half (44%) believed that treating people belonging to high-risk populations would scare other patients away, and 6% openly expressed their dislike of people belonging to high-risk populations. Staff who would offer HIV testing were younger (adjusted odds ratio (aOR) 0.97 per year increase in age, 95% confidence interval (CI):0.97-0.98); trained as a doctor compared to a nurse (aOR 1.79, 95%CI:1.46-2.15); held a bachelor degree or above (aOR 1.34, 95%CI:1.11-1.62); and had previous HIV training (aOR 1.55, 95%CI:1.27-1.89). CONCLUSIONS: Improving HIV training of CHC staff, including addressing stigmatizing attitudes, and improving financial reimbursement may help increase HIV testing coverage in China.

RESUMO

Background Recruitment of people to randomised trials of online interventions presents particular challenges and opportunities. The aim of this study was to evaluate factors associated with the recruitment of people with HIV (PWHIV) and their doctors to the HealthMap trial, a cluster randomised trial of an online self-management program. METHODS: Recruitment involved a three-step process. Study sites were recruited, followed by doctors caring for PWHIV at study sites and finally PWHIV. Data were collected from study sites, doctors and patient participants. Factors associated with site enrolment and patient participant recruitment were investigated using regression models. RESULTS: Thirteen study sites, 63 doctor participants and 728 patient participants were recruited to the study. Doctors having a prior relationship with the study investigators (odds ratio (OR) 13.3; 95% confidence interval (CI) 3.0, 58.7; P = 0.001) was positively associated with becoming a HealthMap site. Most patient participants successfully recruited to HealthMap (80%) had heard about the study from their HIV doctor. Patient enrolment was associated with the number of people with HIV receiving care at the site (ß coefficient 0.10; 95% CI 0.04, 0.16; P = 0.004), but not with employing a clinic or research nurse to help recruit patients (ß coefficient 55.9; 95% CI -2.55, 114.25; P = 0.06). CONCLUSION: Despite substantial investment in online promotion, a previous relationship with doctors was important for doctor recruitment, and doctors themselves were the most important source of patient recruitment to the HealthMap trial. Clinic-based recruitment strategies remain a critical component of trial recruitment, despite expanding opportunities to engage with online communities.

RESUMO

Objective: The study aimed to decentralize hepatitis testing and management services to primary care in China. Methods: A nationwide representative provider survey amongst community health centres (CHCs) using randomized stratified sampling methods was conducted between September and December 2015. One hundred and eighty CHCs and frontline primary care practitioners from 20 cities across three administrative regions of Western, Central and Eastern China were invited to participate. Results: One hundred and forty-nine clinicians-in-charge (79%), 1734 doctors and 1846 nurses participated (86%). Majority of CHCs (80%, 95% CI: 74-87) offered hepatitis B testing, but just over half (55%, 95% CI: 46-65) offered hepatitis C testing. The majority of doctors (87%) and nurses (85%) felt that there were benefits for providing hepatitis testing at CHCs. The major barriers for not offering hepatitis testing were lack of training (54%) and financial support (23%). Multivariate analysis showed that the major determinants for CHCs to offer hepatitis B and C testing were the number of nurses (AOR 1.1) and written policies for hepatitis B diagnosis (AOR 12.7-27.1), and for hepatitis B the availability of reproductive health service. Conclusions: Primary care providers in China could play a pivotal role in screening, diagnosing and treating millions of people with chronic hepatitis B and C in China.

RESUMO

BACKGROUND: China has strengthened its primary care workforce and implemented a wide network of community health centres (CHCs). However, STI testing and management are not currently included in the 'Essential Package of Primary Health Care in China'. Legislation change to encourage STI service delivery would be important, but it is also critical to determine if there are also provider-related opportunities and barriers for implementing effective STI programmes through CHCs if future legislation were to change. METHODS: A national representative survey was conducted between September and December 2015 in a stratified random sample of 180 CHCs based in 20 cities in China. Primary care practitioners (PCPs) provided information on current experiences of STI testing as well as the barriers and facilitators for STI testing in CHCs. Multivariate logistic regression was conducted to determine factors associated with PCPs performing STI testing. RESULTS: 3580 out of 4146 (86%) invited PCPs from 158 CHCs completed the survey. The majority (85%, 95% CI 84% to 87%) of doctors stated that STI testing was an important part of healthcare. However, less than a third (29%, 95% CI 27% to 31%) would perform an STI test if the patients asked. Barriers for performing STI testing included lack of training, concerns about reimbursement, concerns about damage to clinics' reputations and the stigma against key populations. Respondents who reported that they would perform an STI test were likely to be younger, received a bachelor degree or higher, received specific training in STIs, believed that STI test was an important part of healthcare or had resources to perform STI testing. CONCLUSIONS: There is potential for improving STI management in China through upskilling the primary care workforce in CHCs. Specific training in STIs is needed, and other structural, logistical and attitudinal barriers are needed to be addressed.

RESUMO

PURPOSE: China introduced a national policy of developing primary care in 2009, establishing 8,669 community health centers (CHCs) by 2014 that employed more than 300,000 staff. These facilities have been underused, however, because of public mistrust of physicians and overreliance on specialist care. METHODS: We selected a stratified random sample of CHCs throughout China based on geographic distribution and urban-suburban ratios between September and December 2015. Two questionnaires, 1 for lead clinicians and 1 for primary care practitioners (PCPs), asked about the demographics of the clinic and its clinical and educational activities. Responses were obtained from 158 lead clinicians in CHCs and 3,580 PCPs (response rates of 84% and 86%, respectively). RESULTS: CHCs employed a median of 8 physicians and 13 nurses, but only one-half of physicians were registered as PCPs, and few nurses had training specifically for primary care. Although virtually all clinics were equipped with stethoscopes (98%) and sphygmomanometers (97%), only 43% had ophthalmoscopes and 64% had facilities for gynecologic examination. Clinical care was selectively skewed toward certain chronic diseases. Physicians saw a median of 12.5 patients per day. Multivariate analysis showed that more patients were seen daily by physicians in CHCs organized by private hospitals and those having pharmacists and nurses. CONCLUSIONS: Our survey confirms China's success in establishing a large, mostly young primary care workforce and providing ongoing professional training. Facilities are basic, however, with few clinics providing the comprehensive primary care required for a wide range of common physical and mental conditions. Use of CHCs by patients remains low.

RESUMO

BACKGROUND: The leading causes of morbidity and mortality for people in high-income countries living with HIV are now non-AIDS malignancies, cardiovascular disease and other non-communicable diseases associated with ageing. This protocol describes the trial of HealthMap, a model of care for people with HIV (PWHIV) that includes use of an interactive shared health record and self-management support. The aims of the HealthMap trial are to evaluate engagement of PWHIV and healthcare providers with the model, and its effectiveness for reducing coronary heart disease risk, enhancing self-management, and improving mental health and quality of life of PWHIV. METHODS/DESIGN: The study is a two-arm cluster randomised trial involving HIV clinical sites in several states in Australia. Doctors will be randomised to the HealthMap model (immediate arm) or to proceed with usual care (deferred arm). People with HIV whose doctors are randomised to the immediate arm receive 1) new opportunities to discuss their health status and goals with their HIV doctor using a HealthMap shared health record; 2) access to their own health record from home; 3) access to health coaching delivered by telephone and online; and 4) access to a peer moderated online group chat programme. Data will be collected from participating PWHIV (n = 710) at baseline, 6 months, and 12 months and from participating doctors (n = 60) at baseline and 12 months. The control arm will be offered the HealthMap intervention at the end of the trial. The primary study outcomes, measured at 12 months, are 1) 10-year risk of non-fatal acute myocardial infarction or coronary heart disease death as estimated by a Framingham Heart Study risk equation; and 2) Positive and Active Engagement in Life Scale from the Health Education Impact Questionnaire (heiQ). DISCUSSION: The study will determine the viability and utility of a novel technology-supported model of care for maintaining the health and wellbeing of people with HIV. If shown to be effective, the HealthMap model may provide a generalisable, scalable and sustainable system for supporting the care needs of people with HIV, addressing issues of equity of access.

RESUMO

BACKGROUND: This study was a component of the Flinders Telehealth in the Home project, which tested adding home telehealth to existing rehabilitation, palliative care and geriatric outreach services. Due to the known difficulty of transitioning telehealth projects services, a qualitative study was conducted to produce a preferred implementation approach for sustainable and large-scale operations, and a process model that offers practical advice for achieving this goal. METHODS: Initially, semi-structured interviews were conducted with senior clinicians, health service managers and policy makers, and a thematic analysis of the interview transcripts was undertaken to identify the range of options for ongoing operations, plus the factors affecting sustainability. Subsequently, the interviewees and other decision makers attended a deliberative forum in which participants were asked to select a preferred model for future implementation. Finally, all data from the study was synthesised by the researchers to produce a process model. RESULTS: 19 interviews with senior clinicians, managers, and service development staff were conducted, finding strong support for home telehealth but a wide diversity of views on governance, models of clinical care, technical infrastructure operations, and data management. The deliberative forum worked through these options and recommended a collaborative consortium approach for large-scale implementation. The process model proposes that the key factor for large-scale implementation is leadership support, which is enabled by 1) showing solutions to the problems of service demand, budgetary pressure and the relationship between hospital and primary care, 2) demonstrating how home telehealth aligns with health service policies, and 3) achieving clinician acceptance through providing evidence of benefit and developing new models of clinical care. Two key actions to enable change were marketing telehealth to patients, clinicians and policy-makers, and building a community of practice. CONCLUSIONS: The implementation of home telehealth services is still in an early stage. Change agents and a community of practice can contribute by marketing telehealth, demonstrating policy alignment and providing potential solutions for difficult health services problems. This should assist health leaders to move from trials to large-scale services.

RESUMO

OBJECTIVES: To examine the partnerships in population health planning between Medicare Locals (MLs) and Local Health Networks (LHNs) in South Australia, and the factors that facilitated or constrained collaborations, to offer lessons for LHNs and Primary Health Networks. DESIGN, PARTICIPANTS AND SETTING: We conducted a qualitative study using individual interviews with key informants (executive or program leader staff) from the five South Australian MLs and the five South Australian LHNs. A total of 34 interviews were conducted between March and July 2014. RESULTS: Significant work was undertaken by MLs in the process of population health planning and needs assessment. Participants from both MLs and LHNs described examples of collaborative work, including data sharing and synthesis, program implementation and community consultation. The focus of LHNs on acute and intermediate care, the lack of system-level strategies to support collaboration, and constant policy and structural changes leading to uncertainty in the primary health care landscape were perceived as key barriers to collaboration. CONCLUSIONS: The experience of MLs and their achievements in building relationships and trust with stakeholders in their regions, including LHNs, provide valuable lessons for the new Primary Health Networks in Australia.

RESUMO

OBJECTIVE: To examine whether there have been recent changes in Australian antiretroviral treatment (ART) prescribers' perceptions and practices relating to early ART initiation, which was defined as commencing ART when a patient's CD4+ T-cell count approaches 500 cells/mm3 or immediately after a patient is diagnosed with HIV. DESIGN, PARTICIPANTS AND SETTING: Self-completed, anonymous, cross-sectional surveys, targeting all ART prescribers in Australia, were conducted online in 2012 and 2013. The surveys included questions on prescriber factors, CD4+ T-cell count at which prescribers would most strongly recommend ART initiation, and perceived patient characteristics that could change prescribers' practices of early initiation of ART. MAIN OUTCOME MEASURES: Proportions of ART prescribers recommending early ART initiation. RESULTS: We analysed responses from 108 participants in 2012 and 82 participants in 2013. In both years, more male than female prescribers participated. The median age of participants was 49 years in 2012 and 50 years in 2013. In both rounds, over 60% had more than 10 years' experience in treating HIV-positive patients. More prescribers in 2013 stated that they would most strongly recommend early ART initiation compared with those in 2012 (50.0% [95% CI, 38.7%-61.3%] v 26.9% [95% CI, 18.8%-36.2%]; P=0.001). The prescribers' primary concern was more about individual patient than public health benefit. Out of 824 patients for whom ART was initiated, as reported by prescribers in 2013, only 108 (13.1% [95% CI, 10.9%-15.6%]) were given ART primarily to prevent onward HIV transmission. The number of patients for whom ART was initiated was significantly associated with prescribers' HIV caseload even after adjusting for prescriber type (adjusted odds ratio, 1.73 [95% CI, 1.47-2.03]; P<0.001); of the 37 who had initiated ART for 10 or more patients, 29 had a high HIV caseload. In 2013, 60 prescribers (73.2% [95% CI, 62.2%-82.4%]) reported that they routinely recommended ART to treatment-naive, asymptomatic patients with a CD4+ T-cell count of 350-500 cells/mm3. CONCLUSION: Our findings show increasing acceptance of and support for early ART initiation primarily as treatment and not as prevention.

RESUMO

As the management of HIV changes and demand for HIV health services in primary care settings increases, new approaches to engaging the general practice workforce with HIV medicine are required. This paper reports on qualitative research conducted with 47 clinicians who provide HIV care in general practice settings around Australia, including accredited HIV s100 prescribers as well as other GPs and general practice nurses. Balanced numbers of men and women took part; less than one-quarter were based outside of urban metropolitan settings. The most significant workforce challenges that participants said they faced in providing HIV care in general practice were keeping up with knowledge, navigating low caseload and regional issues, balancing quality care with cost factors, and addressing the persistent social stigma associated with HIV. Strategic responses developed by participants to address these challenges included thinking more creatively about business and caseload planning, pursuing opportunities to share care with specialist clinicians, and challenging prejudiced attitudes amongst patients and colleagues. Understanding and supporting the needs of the general practice workforce in both high and low HIV caseload settings will be essential in ensuring Australia has the capacity to respond to emerging priorities in HIV prevention and care.

RESUMO

Research has shown that social representations of HIV can constitute barriers to health workers' willingness to provide HIV care. Considering a growing shortage in the HIV primary workforce in Western countries, we examine how HIV is perceived today by doctors involved in its care. In 1989 Sontag predicted that once the virus became better understood and treatable, the dehumanizing meanings that defined the early epidemic would vanish and HIV would turn into an ordinary illness. However, research shows that HIV still carries stigma, including in the health care sector. Drawing on qualitative interviews, we found that HIV doctors in Australia perceived HIV as a far-from-ordinary chronic illness because of its extraordinary history and its capacity to extend in multiple clinical and social directions. These rarely explored perspectives can contribute to the social reframing of HIV and to strategies to build a dedicated HIV workforce in Australia and elsewhere.

RESUMO

BACKGROUND: Co-designed educational materials could significantly improve the likelihood of patients and visitors (consumers) escalating care through hospital systems. The objective was to investigate patients' and visitors' knowledge and confidence in recognizing and reporting patient deterioration in hospitals before and after exposure to educational materials. METHODS: A multimethod design involved a convenience sample of patients and visitors at a South Australian hospital. Knowledge and confidence of participants to report patient deterioration was assessed using a validated questionnaire. Baseline group was surveyed, and a second group was surveyed after exposure to a poster and on-hold message relating to consumer-initiated escalation-of-care. Nominal data were examined using chi-square analysis, and ordinal data using the Mann-Whitney U test. Open-ended questions were examined using thematic analysis. RESULTS: A total of 407 participants completed the study, 203 undertook the baseline survey, and 204 the postintervention survey. Respondents exposed to the educational materials reported significantly higher recognition of responsibility to report concerns about patient deterioration compared to controls (86.3% vs. 73.1%; p = 0.007). Respondents exposed to the educational materials also had better ability to identify signs that a patient was becoming sicker compared to controls (77.5% vs. 71.3%, p = 0.012). Four overarching themes emerged from the questions: patient/visitor understanding of key messages, patient/visitor recognition of deterioration, patient/visitor response to deterioration and patient/visitor recommendations. CONCLUSION: Following educational interventions, patients and visitors report improved awareness of their role in recognizing and responding to clinical deterioration. They advise additional active interventions and caution that the materials should accommodate language, cultural, and disability needs.

RESUMO

This study explores Australian prescribers' attitudes towards Treatment as Prevention (TasP) and their practices around initiating combination antiretroviral treatment (cART) for HIV. A brief online survey was conducted nationally amongst antiretroviral treatment (ART) prescribers in Australia. The sample broadly represented ART prescribers in Australia (N = 108), with 40.7% general practitioners (GPs), 25.9% sexual health clinic-based physicians and 21.3% hospital-based infectious diseases physicians. About 60% of respondents had been treating HIV-positive patients for more than 10 years. Respondents estimated that about 70-80% of all their HIV-positive patients were receiving ART. Over half of the prescribers agreed very strongly that their primary concern in recommending cART initiation was clinical benefit to individual patients rather than any population benefit. A majority of the prescribers (68.5%) strongly endorsed cART initiation before CD4+ T-cell count drops below 350 cells/mm(3), and a further 22.2% strongly endorsed cART initiation before CD4+ T-cell count drops below 500 cells/mm(3). Regarding the optimal timing of cART initiation, this study shows that prescribers in Australia in 2012 focus primarily on the benefits for their individual patients. Prescribers may need more convincing evidence of individual health benefits or increased knowledge about the population health benefits for a TasP approach to be effective in Australia.

RESUMO

Mate choice is fundamental to sexual selection, yet little is known about underlying physiological mechanisms that influence female mating decisions. We investigated the endocrine underpinnings of female mate choice in the African cichlid Astatotilapia burtoni, a non-seasonal breeder. In addition to profiling behavioral and hormonal changes across the female reproductive cycle, we tested two hypotheses regarding possible factors influencing female mate choice. We first asked whether female mate choice is influenced by male visual and/or chemical cues. A. burtoni females were housed for one full reproductive cycle in the center of a dichotomous choice apparatus with a large (attractive) or small (unattractive) conspecific male on either side. Females associated mostly with small, less attractive males, but on the day of spawning reversed their preference to large, attractive males, with whom they mated almost exclusively, although this choice depended on the relative amount of androgens released into the water by small males. We next asked whether male behavior or androgen levels change in relation to the stimulus females' reproductive state. We found that stimulus male aggression decreased and reproductive displays increased as the day of spawning approached. Moreover male testosterone levels changed throughout the females' reproductive cycle, with larger males releasing more testosterone into the water than small males. Our data suggest that female association in a dichotomous choice assay is only indicative of the actual mate choice on the day of spawning. Furthermore, we show that male behavior and hormone levels are dependent on the reproductive state of conspecific females.

RESUMO

BACKGROUND: HIV has become a chronic manageable infection in the developed world, and early and lifelong treatment has the potential to significantly reduce transmission rates in the community. A skilled and motivated HIV medical workforce will be required to achieve these health management and prevention outcomes, but concerns have been noted in a number of settings about the challenges of recruiting a new generation of clinicians to HIV medicine. METHODS: As part of a larger qualitative study of the HIV general practice workforce in Australia, in-depth interviews were conducted with 31 general practitioners accredited to prescribe HIV medications in community settings. A thematic analysis was conducted of the de-identified transcripts, and this paper describes and interprets accounts of the rewards of pursuing and sustaining an engagement with HIV medicine in general practice settings. RESULTS: The rewards of initially becoming involved in providing care to people living with HIV were described as interest and inspiration, community calling and right place, right time. The rewards which then supported and sustained that engagement over time were described as challenge and change, making a difference and enhanced professional identity. Participants viewed the role of primary care doctor with special expertise in HIV as occupying an ideal interface between the 'coalface' and the 'cutting edge', and offering a unique opportunity for general practitioners to feel intimately connected to both community needs and scientific change. CONCLUSIONS: Approaches to recruiting and retaining the HIV medical workforce should build upon the intellectual and social rewards of this work, as well as the sense of professional belonging and connection which is imbued between both doctors and patients and across the global and national networks of HIV clinicians. Insights regarding the rewards of engaging with HIV medicine may also be useful in enhancing the prospect of general practice as a career, and strengthening retention and job satisfaction among the existing general practice workforce.

RESUMO

BACKGROUND: This study sought to gain insight into how Deaf Australians who use Auslan as their primary language perceive their English literacy and if they feel that they can sufficiently access preventative and ongoing health care information, and to explore their views in regards to accessing information in Auslan. METHODS: A phenomenological, inductive study, with data collected through 72 semi-structured interviews with Deaf Auslan users identified through non-probabilistic, purposeful and network sampling. Data was thematically analysed for identification of issues related to healthcare information access through English. RESULTS: Deaf people experience barriers in accessing healthcare information because of limited English literacy and a lack of information being available in Auslan, apart from when Auslan interpreters are present in health care appointments. CONCLUSION: Many Deaf people in Australia lack consistent access to preventative and ongoing health care information. It is important to be aware of the English literacy levels of patients. More funding is needed for the provision of interpreting services in other healthcare contexts and the translation of materials into Auslan.

RESUMO

BACKGROUND: Although general practitioners (GPs) play a central role in responding to human immunodeficiency virus (HIV) in Australia, the social history of their contribution in the early years has remained largely untold. METHODS: In-depth interviews were conducted with 21 GPs who provided HIV care between 1982 and 1996. De-identified transcripts were broadly coded in NVivo, then analysed for themes regarding GP experiences during the early years. RESULTS: Participants recalled a time of death, fear and prejudice, with large numbers of patients diagnosed with and dying from a highly stigmatised disease. An enduring emotional legacy resulted, with GPs developing survival strategies such as better managing relationships with patients, seeking mental health support and reducing working hours. DISCUSSION: These GPs represent the first generation of GPs in Australia caring for people with HIV. Understanding their experiences can inform and inspire the next generation, who inherit a much brighter future for HIV care.
