Knowledge, attitudes, and practice behaviors of oncology advanced practice nurses regarding advanced care planning for patients with cancer.
Purpose/Objectives: To establish initial reliability and validity of a Web-based survey focused on oncology advanced practice nurses\u27 (APNs\u27) knowledge, attitudes, and practice behaviors regarding advanced care planning, and to obtain preliminary understanding of APNs\u27 knowledge, attitudes, and practice behaviors and perceived barriers to advanced care planning.
Design: Descriptive, cross-sectional, pilot survey study.
Setting: The eastern United States.Sample: 300 oncology APNs.Methods: Guided by the Theory of Planned Behavior, a knowledge, attitudes, and practice behaviors survey was developed and reviewed for content validity. The survey was distributed to 300 APNs via e-mail and sent again to the 89 APNs who responded to the initial survey. Exploratory factor analysis was used to examine the construct validity and test-retest reliability of the survey\u27s attitudinal and practice behavior portions.
Main Research Variables: Respondents\u27 demographics, knowledge, attitudes, practice behaviors, and perceived barriers to advanced care planning practice.
Findings: Exploratory factor analysis yielded a five-factor solution from the survey\u27s attitudes and practice behavior portions with internal consistency using Cronbach alpha. Respondents achieved an average of 67% correct answers in the 12-item knowledge section and scored positively in attitudes toward advanced care planning. Their practice behavior scores were marginally positive. The most common reported barriers were from patients\u27 and families\u27 as well as physicians\u27 reluctance to discuss advanced care planning.
Conclusions: The attitudinal and practice behaviors portions of the survey demonstrated preliminary construct validity and test-retest reliability. Regarding advanced care planning, respondents were moderately knowledgeable, but their advanced care planning practice was not routine.Implications for Nursing: Validly assessing oncology APNs\u27 knowledge, attitudes, and practice behaviors regarding advanced care planning will enable more tailored approaches to improve end-of-life care outcomes

Ecto- and arbuscular mycorrhizal symbiosis can induce tolerance to toxic pulses of phosphorus in jarrah (Eucalyptus marginata) seedlings
In common with many plants native to low P soils, jarrah (Eucalyptus marginata) develops toxicity symptoms upon exposure to elevated phosphorus (P). Jarrah plants can establish arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) associations, along with a non-colonizing symbiosis described recently. AM colonization is known to influence the pattern of expression of genes required for P uptake of host plants and our aim was to investigate this phenomenon in relation to P sensitivity. Therefore, we examined the effect on hosts of the presence of AM and ECM fungi in combination with toxic pulses of P and assessed possible correlations between the induced tolerance and the shoot P concentration. The P transport dynamics of AM (Rhizophagus irregularis and Scutellospora calospora), ECM (Scleroderma sp.), non-colonizing symbiosis (Austroboletus occidentalis), dual mycorrhizal (R. irregularis and Scleroderma sp.), and non-mycorrhizal (NM) seedlings were monitored following two pulses of P. The ECM and A. occidentalis associations significantly enhanced the shoot P content of jarrah plants growing under P-deficient conditions. In addition, S. calospora, A. occidentalis, and Scleroderma sp. all stimulated plant growth significantly. All inoculated plants had significantly lower phytotoxicity symptoms compared to NM controls 7 days after addition of an elevated P dose (30 mg P kg−1 soil). Following exposure to toxicity-inducing levels of P, the shoot P concentration was significantly lower in R. irregularis-inoculated and dually inoculated plants compared to NM controls. Although all inoculated plants had reduced toxicity symptoms and there was a positive linear relationship between rank and shoot P concentration, the protective effect was not necessarily explained by the type of fungal association or the extent of mycorrhizal colonization
Consensus statement on abusive head trauma in infants and young children
Abusive head trauma (AHT) is the leading cause of fatal head injuries in children younger than 2Â years. A multidisciplinary team bases this diagnosis on history, physical examination, imaging and laboratory findings. Because the etiology of the injury is multifactorial (shaking, shaking and impact, impact, etc.) the current best and inclusive term is AHT. There is no controversy concerning the medical validity of the existence of AHT, with multiple components including subdural hematoma, intracranial and spinal changes, complex retinal hemorrhages, and rib and other fractures that are inconsistent with the provided mechanism of trauma. The workup must exclude medical diseases that can mimic AHT. However, the courtroom has become a forum for speculative theories that cannot be reconciled with generally accepted medical literature. There is no reliable medical evidence that the following processes are causative in the constellation of injuries of AHT: cerebral sinovenous thrombosis, hypoxic-ischemic injury, lumbar puncture or dysphagic choking/vomiting. There is no substantiation, at a time remote from birth, that an asymptomatic birth-related subdural hemorrhage can result in rebleeding and sudden collapse. Further, a diagnosis of AHT is a medical conclusion, not a legal determination of the intent of the perpetrator or a diagnosis of murder. We hope that this consensus document reduces confusion by recommending to judges and jurors the tools necessary to distinguish genuine evidence-based opinions of the relevant medical community from legal arguments or etiological speculations that are unwarranted by the clinical findings, medical evidence and evidence-based literature
