qPCR Assays for Sensitive and Rapid Detection of Quambalaria Species from Plant Tissues.

Several species from the genus Quambalaria (order Microstromatales) cause diseases on eucalypts (Eucalyptus and related genera) both in plantations and natural ecosystems. We developed real-time quantitative PCR (qPCR) assays to rapidly detect and distinguish five Quambalaria species. The design of the species-specific qPCR assay for each species, Q. pitereka (PIT), Q. coyrecup (COR), Q. cyanescens (CYN), Q. pusilla (PUS), and Q. eucalypti (EUC), was based on the ITS region and was evaluated for specificity and sensitivity. The PIT, COR, and CYN qPCR assays could amplify as little as 10 fg µl-1 from pure cultures, whereas PUS and EUC qPCR assays could amplify 100 fg µl-1 of their target species. The PIT, COR, and CYN qPCR assays were further validated using naturally and artificially infected samples of their plant host Corymbia calophylla. These assays will be used for rapid diagnostics and future experiments on the infection process.

Early Intervention in Psychosis: Effectiveness and Implementation of a Combined Exercise and Health Behavior Intervention Within Routine Care.

Aim: Young people with psychosis have higher rates of obesity, premature cardiovascular disease, and death compared to non-psychotic peers in the general population due to changes in metabolic regulation linked to antipsychotic medication and adverse health risk behaviors. The aim of this paper is to outline the development, implementation, and evaluation of a combined 12-week exercise and health behavior intervention delivered as part of an Early Intervention in Psychosis (EIP) routine service, within the UK. Methods: Participants (n = 27) completed a 12-week combined intervention program, engaging in weekly, 90-min sessions comprising a healthy behavior education session (45 min), followed by a facilitated exercise session (45 min). Anthropometric data from participants (n = 26) were collected at baseline, 12 weeks, and 12 months post-intervention. Health behaviors and clinical measurements were assessed at baseline and 12 months. Results: Mean baseline data suggests participants were at an increased health risk on entry to the program, with elevated values in mean body mass index (BMI; 70% overweight/obese), waist circumference, resting heart rate, and triglycerides. Fifty percent reported smoking daily, 64% ate < 5 fruits/vegetables per day, and 52% of participants were prescribed highly obesogenic antipsychotic medications (i.e., Olanzapine). At 12 weeks and 12 months, no changes were observed in mean BMI, waist circumference or any other clinical variable (p > 0.05). At 12 months, participants reported a positive impact on health behaviors including improved diet, increased physical activity levels, and cessation of substance use (n = 2), alcohol use (n = 2), and smoking (n = 4). Focus groups captured participant experiences, engagement with and satisfaction with the program, including challenges/barriers to program adherence. Conclusions: The 12-week exercise and health behaviors program supported participants to attenuate their physical health risk which was sustained at 12-month follow-up. Self-reported positive health behavior changes are likely to have contributed to the prevention of excessive weight gain in this high-risk period. The evaluation was designed to have validity for a "real world EIP setting" and reflect the complexity of delivery to this participant group. Evaluation findings influenced subsequent commissioning of the physical health intervention as an ongoing element of routine EIP care within the participant site.

General practice nurses and physicians and end of life: a systematic review of models of care.

BACKGROUND: General practitioners (GPs) and general practice nurses (GPNs) face increasing demands to provide palliative care (PC) or end-of-life care (EoLC) as the population ages. In order to maximise the impact of GPs and GPNs, the impact of different models of care that have been developed to support their practice of EoLC needs to be understood. OBJECTIVE: To examine published models of EoLC that incorporate or support GP and GPN practice, and their impact on patients, families and the health system. METHOD: Systematic literature review. Data included papers (2000 to 2017) sought from Medline, Psychinfo, Embase, Joanna Briggs Institute and Cochrane databases. RESULTS: From 6209 journal articles, 13 papers reported models of care supporting the GP and GPN's role in EoLC or PC practice. Services and guidelines for clinical issues have mixed impact on improving symptoms, but improved adherence to clinical guidelines. National Frameworks facilitated patients being able to die in their preferred place. A single specialist PC-GP case conference reduced hospitalisations, better maintained functional capacity and improved quality of life parameters in both patients with cancer and without cancer. No studies examined models of care aimed at supporting GPNs. CONCLUSIONS: Primary care practitioners have a natural role to play in EoLC, and most patient and health system outcomes are substantially improved with their involvement. Successful integrative models need to be tested, particularly in non-malignant diseases. Such models need to be explored further. More work is required on the role of GPNs and how to support them in this role.

Facilitators and barriers to general practitioner and general practice nurse participation in end-of-life care: systematic review.

BACKGROUND: General practitioners (GPs) and general practice nurses (GPNs) face increasing demands to provide palliative care (PC) or end-of-life care (EoLC) as the population ages. To enhance primary EoLC, the facilitators and barriers to their provision need to be understood. OBJECTIVE: To provide a comprehensive description of the facilitators and barriers to GP and GPN provision of PC or EoLC. METHOD: Systematic literature review. Data included papers (2000 to 2017) sought from Medline, PsycInfo, Embase, Joanna Briggs Institute and Cochrane databases. RESULTS: From 6209 journal articles, 62 reviewed papers reported the GP's and GPN's role in EoLC or PC practice. Six themes emerged: patient factors; personal GP factors; general practice factors; relational factors; co-ordination of care; availability of services. Four specific settings were identified: aged care facilities, out-of-hours care and resource-constrained settings (rural, and low-income and middle-income countries). Most GPs provide EoLC to some extent, with greater professional experience leading to increased comfort in performing this form of care. The organisation of primary care at practice, local and national level impose numerous structural barriers that impede more significant involvement. There are potential gaps in service provision where GPNs may provide significant input, but there is a paucity of studies describing GPN routine involvement in EoLC. CONCLUSIONS: While primary care practitioners have a natural role to play in EoLC, significant barriers exist to improved GP and GPN involvement in PC. More work is required on the role of GPNs.

Consumer involvement in emergency medicine research: Lessons from engaging sepsis survivors.

Collaboration with consumers is an emerging focus for medical researchers worldwide. Public involvement is increasingly encouraged, and in some cases stipulated by funding bodies, in order to secure financial support. While consumer involvement could be viewed as another hurdle in the funding application process, it can add immense value to research outcomes. However, given the diverse and transient nature of our consumer group, how can we develop meaningful public engagement in emergency medicine research?

General practice physicians' and nurses' self-reported multidisciplinary end-of-life care: a systematic review.

BACKGROUND: General practitioners (GPs) and general practice nurses (GPNs) face increasing demands to provide end-of-life care (EoLC) as the population ages. To enhance primary palliative care (PC), the care they provide needs to be understood to inform best practice models of care. OBJECTIVE: To provide a comprehensive description of the self-reported role and performance of GPs and GPNs in (1) specific medical/nursing roles, (2) communication, (3) care co-ordination, (4) access and out-of-hours care, and (5) multidisciplinary care. METHOD: Systematic literature review. Data included papers (2000 to 2017) sought from Medline, Psychinfo, Embase, Joanna Briggs Institute and Cochrane databases. RESULTS: From 6209 journal articles, 29 reviewed papers reported the GPs' and GPNs' role in EoLC or PC practice. GPs report a central role in symptom management, treatment withdrawal, non-malignant disease management and terminal sedation. Information provision included breaking bad news, prognosis and place of death. Psychosocial concerns were often addressed. Quality of communication depended on GP-patient relationships and GP skills. Challenges were unrealistic patient and family expectations, family conflict and lack of advance care planning. GPs often delayed end-of-life discussions until 3 months before death. Home visits were common, but less so for urban, female and part-time GPs. GPs co-ordinated care with secondary care, but in some cases parallel care occurred. Trust in, and availability of, the GP was critical for shared care. There was minimal reference to GPNs' roles. CONCLUSIONS: GPs play a critical role in palliative care. More work is required on the role of GPNs, case finding and models to promote shared care, home visits and out-of-hours services.

General practice palliative care: patient and carer expectations, advance care plans and place of death-a systematic review.

BACKGROUND: With an increasing ageing population in most countries, the role of general practitioners (GPs) and general practice nurses (GPNs) in providing optimal end of life (EoL) care is increasingly important. OBJECTIVE: To explore: (1) patient and carer expectations of the role of GPs and GPNs at EoL; (2) GPs' and GPNs' contribution to advance care planning (ACP) and (3) if primary care involvement allows people to die in the place of preference. METHOD: Systematic literature review. DATA SOURCES: Papers from 2000 to 2017 were sought from Medline, Psychinfo, Embase, Joanna Briggs Institute and Cochrane databases. RESULTS: From 6209 journal articles, 51 papers were relevant. Patients and carers expect their GPs to be competent in all aspects of palliative care. They valued easy access to their GP, a multidisciplinary approach to care and well-coordinated and informed care. They also wanted their care team to communicate openly, honestly and empathically, particularly as the patient deteriorated. ACP and the involvement of GPs were important factors which contributed to patients being cared for and dying in their preferred place. There was no reference to GPNs in any paper identified. CONCLUSIONS: Patients and carers prefer a holistic approach to care. This review shows that GPs have an important role in ACP and that their involvement facilitates dying in the place of preference. Proactive identification of people approaching EoL is likely to improve all aspects of care, including planning and communicating about EoL. More work outlining the role of GPNs in end of life care is required.

Systematic review of general practice end-of-life symptom control.

BACKGROUND: End of life care (EoLC) is a fundamental role of general practice, which will become more important as the population ages. It is essential that general practice's role and performance of at the end of life is understood in order to maximise the skills of the entire workforce. OBJECTIVE: To provide a comprehensive description of the role and performance of general practitioners (GPs) and general practice nurses (GPNs) in EoLC symptom control. METHOD: Systematic literature review of papers from 2000 to 2017 were sought from Medline, PsycINFO, Embase, Joanna Briggs Institute and Cochrane databases. RESULTS: From 6209 journal articles, 46 papers reported GP performance in symptom management. There was no reference to the performance of GPNs in any paper identified. Most GPs expressed confidence in identifying EoLC symptoms. However, they reported lack of confidence in providing EoLC at the beginning of their careers, and improvements with time in practice. They perceived emotional support as being the most important aspect of EoLC that they provide, but there were barriers to its provision. GPs felt most comfortable treating pain, and least confident with dyspnoea and depression. Observed pain management was sometimes not optimal. More formal training, particularly in the use of opioids was considered important to improve management of both pain and dyspnoea. CONCLUSIONS: It is essential that GPs receive regular education and training, and exposure to EoLC from an early stage in their careers to ensure skill and confidence. Research into the role of GPNs in symptom control needs to occur.

The role of primary care in early detection and follow-up of cancer.

Primary care providers have important roles across the cancer continuum, from encouraging screening and accurate diagnosis to providing care during and after treatment for both the cancer and any comorbid conditions. Evidence shows that higher cancer screening participation rates are associated with greater involvement of primary care. Primary care providers are pivotal in reducing diagnostic delay, particularly in health systems that have long waiting times for outpatient diagnostic services. However, so-called fast-track systems designed to speed up hospital referrals are weakened by significant variation in their use by general practitioners (GPs), and affect the associated conversion and detection rates. Several randomized controlled trials have shown primary care-led follow-up care to be equivalent to hospital-led care in terms of patient wellbeing, recurrence rates and survival, and might be less costly. For primary care-led follow-up to be successful, appropriate guidelines must be incorporated, clear communication must be provided and specialist care must be accessible if required. Finally, models of long-term cancer follow-up are needed that provide holistic care and incorporate management of co-morbid conditions. We discuss all these aspects of primary care, focusing on the most common cancers managed at the GP office-breast, colorectal, prostate, lung and cervical cancers.
