School health teams commonly address the needs of students with asthma, which requires specific knowledge and skills. To develop a skilled school health team, a competency-based framework for managing asthma in schools was developed. A modified Delphi with 31 panelists was completed. Consensus (≥80% agreement) was reached for all 148 items regarding the appropriateness as a minimum competency for asthma care in schools. The resultant Colorado Competency Framework for Asthma Care in Schools guided the development and pilot testing of a continuing education curriculum for school nurses...

BACKGROUND: Between 20% and 35% of prostate cancer (PCa) patients who undergo treatment with curative intent (ie, surgery or radiation therapy) for localized disease will experience biochemical recurrence (BCR). Alterations in the insulin-like growth factor (IGF) axis and PTEN expression have been implicated in the development and progression of several human tumors including PCa. We examined the expression of the insulin receptor (INSR), IGF-1 receptor (IGF-1R), PTEN, and AKT in radical prostatectomy tissue of patients who developed BCR post-surgery...

Active surveillance (AS) has emerged as a beneficial strategy for management of low risk prostate cancer (PCa) and prevention of overtreatment of indolent disease. However, selection of patients for AS using traditional 12-core transrectal prostate biopsy is prone to sampling error and presents a challenge for accurate risk stratification. In fact, around a third of men are upgraded on repeat biopsy which disqualifies them as appropriate AS candidates. This uncertainty affects adoption of AS among patients and physicians, leading to current AS protocols involving repetitive prostate biopsies and unclear triggers for progression to definitive treatment...

Prostate cancer (PCa) is one of the few neoplasms that are not well served by 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET). As a result, a number of PET tracers have been developed to target particular biological features of PCa. Such agents can be used for diagnosis, staging, identification of biochemical recurrence (BCR) and evaluation of metastatic disease. Here, we focus on primary disease and local staging. To date, magnetic resonance imaging (MRI) has proven superior to PET in the imaging of primary PCa...

MRI-targeted biopsy of the prostate appears to have the potential to reduce the high rates of underdiagnosis and overdiagnosis associated with the current diagnostic standard of transrectal ultrasound guided systematic biopsy. Direct or "in bore" MRI-guided biopsy is one of the three methods for MRI-targeted core needle sampling of suspicious, generally Pi-RADS 4 or 5, foci within the prostate, and our early experience suggests the approach demonstrates substantial utility and promise in the care of patients with prostate cancer...

BACKGROUND: Clinical experience highlights the wide heterogeneity of primary prostate cancer (PPCa), even when potentially related to the same grade and stage. Currently available prediction tools and biomarkers do not always allow for early recognition of PPCa aggressive phenotype, sometimes making it impossible to distinguish among men harbouring indolent tumours or life-threatening disease. OBJECTIVE: To establish a novel ex vivo/in vitro model suitable to estimate the invasive phenotype of PPCa cells (PPCaC)...

PURPOSE: Patients with prostate cancer (PCa) containing Gleason pattern (GP) 5 disease experience a greater and earlier incidence of prostate cancer-specific mortality (PCSM) than general PCa patients. This affords the statistical power to compare PCSM outcomes among different treatment modalities even when restricting the analysis to patients treated in the modern era. The purpose of the present study was to compare the survival outcomes among patients with GP 5 PCa on needle core biopsy or transurethral resection of the prostate who underwent extremely dose-escalated radiation therapy (RT; exemplified by external beam RT with a brachytherapy boost [EBRT + BT]) versus radical prostatectomy (RP) in the modern era...

BACKGROUND: Studies on the association between two single nucleotide polymorphisms (SNPs) in estrogen receptor α (ERα), PvuII (rs2234693 T>C) and XbaI (rs9340799 A>G), and the prostate cancer risk are inconsistent. Therefore, we performed a meta-analysis to derive a more accurate estimation of this relationship. METHODS: A literature search of PubMed, Embase, Web of Science databases until October 1, 2016, was conducted. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of this association...

A 72-year-old man with prostate cancer (stage T3b, Gleason score 7) treated by radical prostatectomy was found to have biochemical failure (prostate-specific antigen 8.5 ng/mL) and a suspicious growing nodularity at the left prostate bed on MRI. F-fluorocholine PET/CT failed to demonstrate any site of uptake suggestive of malignancy. A bone scan did exclude bone metastases. Ga-PSMA PET/CT revealed various positive lymph nodes in the supraclavicular, mediastinal, and hilar regions. This was confirmed on F-DCFPyl PET/CT, with the addition of a suspicious right axillary lymph node...

Behavioral interventions for older adults can reduce difficulties in performing daily activities, hospitalizations, and mortality risk. The success of behavior change interventions, however, can be affected by a participant's readiness to adopt changes. This study evaluates whether socioeconomic conditions, particularly financial strain affording food, are associated with readiness to change. We conducted a cross-sectional, descriptive study of baseline data from disabled older adults ( N = 147) participating in an intervention to reduce physical disability...
