Following legislative changes in the availability and prescribing of medicinal cannabis in Australia, we sought to understand prospectively the nature of information seeking and requests for medicinal cannabis in consultations between palliative care clinicians and patients with cancer. The 104 discussions were overwhelmingly initiated by patients and carers (93%) and were for a variety of symptoms, reflecting high levels of patient interest in the use of medicinal cannabis in cancer.  相似文献

OBJECTIVE: To compare function and quality of life in community-dwelling stroke survivors at 1, 3, and 5 years after stroke. DESIGN: A community-based, cross-sectional study of 3 retrospective cohorts. SETTING: Community-dwelling stroke survivors in Australia. PARTICIPANTS: The 3 cohorts comprised 30 participants each at 1, 3, and 5 years poststroke discharge from a tertiary referral hospital. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Stroke severity, comorbidity, medications used, and demographic information were recorded. Poststroke function was assessed using the Modified Rankin Scale, Mini-Mental State Examination, Stroke Impact Scale, and Multidimensional Scale of Perceived Social Support. RESULTS: This cross-sectional study provides insights into trends in stroke survivors over time. A high proportion of stroke survivors use community services, even those who are independent with activities of daily living. Although there was little attrition in medication use over time except for warfarin, this was from a baseline of suboptimal compliance and adherence with stroke preventive therapies. Stroke survivors report high levels of perceived social support; however, emotional well-being was low overall. The data suggest that those who are independent at 1 year tend to remain independent, although this was an extrapolation from serial cross-sections and needs to be explored in a longitudinal study. CONCLUSIONS: Stroke survivors' function does not change significantly over time. A high proportion of survivors require community services. The development of needs-related effective long-term service delivery models is required.  相似文献

Purpose

The pediatric NSQIP program is in the early stages of facilitated surgical quality improvement for children. The objective of this study is to describe the initial experience of the first Canadian Children’s Hospital participant in this program.

Method

Randomly sampled surgical cases from the “included” case list were abstracted into the ACS-NSQIP database. These surgical procedure-specific data incorporate patient risk factors, intraoperative details, and 30 day outcomes to generate annual reports which provide hierarchical ranking of participant hospitals according to their risk-adjusted outcomes.

Results

Our first risk-adjusted report identified local improvement opportunities based on our rates of surgical site infection (SSI) and urinary tract infection (UTI). We developed and implemented an engagement strategy for our stakeholders, performed literature reviews to identify practice variation, and conducted case control studies to understand local risk factors for our SSI/UTI occurrences. We have begun quality improvement activities targeting reduction in rates of SSI and UTI with our general surgery division and ward nurses, respectively.

Conclusions

The NSQIP pediatric program provides high quality outcome data that can be used in support of quality improvement. This process requires multidisciplinary teamwork, systematic stakeholder engagement, clinical research methods and process improvement through engagement and culture change.  相似文献

Precise regulation of bone resorption is critical for skeletal homeostasis. We report a 32‐year‐old man with a panostotic expansile bone disease and a massive hemorrhagic mandibular tumor. Originally from Mexico, he was deaf at birth and became bow‐legged during childhood. There was no family history of skeletal disease. Puberty occurred normally, but during adolescence he experienced difficulty straightening his limbs, sustained multiple fractures, and developed a bony tumor on his chin. By age 18 years, all limbs were misshapen. The mandibular mass grew and protruded from the oral cavity, extending to the level of the lower ribs. Other bony defects included a similar maxillary mass and serpentine limbs. Upon referral at age 27 years, biochemical studies showed serum alkaline phosphatase of 1760 U/L (Nl: 29‐111) and other elevated bone turnover markers. Radiography of the limbs showed medullary expansion and cortical thinning with severe bowing. Although the jaw tumors were initially deemed inoperable, mandibular mass excision and staged partial maxillectomy were eventually performed. Tumor histopathology showed curvilinear trabeculae of woven bone on a background of hypocellular fibrous tissue. Fibrous dysplasia of bone was suspected, but there was no mutation in codon 201 of GNAS in samples from blood or tumor. His clinical and radiographic findings, elevated serum markers, and disorganized bone morphology suggested amplified receptor activator of NF‐κB (RANK) signaling, even though his disorder differed from conditions with known constitutive activation of RANK signaling (eg, familial expansile osteolysis). We found a unique 12‐base pair duplication in the signal peptide of TNFRSF11A, the gene that encodes RANK. No exon or splice site mutations were found in the genes encoding RANK ligand or osteoprotegerin. Alendronate followed by pamidronate therapies substantially decreased his serum alkaline phosphatase activity. This unique patient expands the phenotypes and genetic basis of the mendelian disorders of RANK signaling activation. © 2014 American Society for Bone and Mineral Research.  相似文献

Purpose

Anabolic steroid (AS) misuse is widespread amongst recreational bodybuilders; however, their effects on the cardiovascular system are uncertain. Our aim was to document the impact of AS use on cardiac structure, function and the presence of focal fibrosis using the gold standard cardiovascular magnetic resonance imaging (CMR).

Methods

A cross-sectional cohort design was utilised with 21 strength-trained participants who underwent CMR imaging of the heart and speckle-tracking echocardiography. Thirteen participants (30 ± 5 years) taking AS for at least 2 years and currently on a “using”-cycle were compared with age and training-matched controls (n = 8; 29 ± 6 years) who self-reported never having taken AS (NAS).

Results

AS users had higher absolute left ventricular (LV) mass (220 ± 45 g) compared to NAS (163 ± 27 g; p < 0.05) but this difference was removed when indexed to fat-free mass. AS had a reduced right ventricular (RV) ejection fraction (AS 51 ± 4 % vs. NAS 59 ± 5 %; p < 0.05) and a significantly lower left ventricular E’:A’ myocardial tissue velocity ratio [AS 0.99(0.54) vs. NAS 1.78(0.46) p < 0.05] predominantly due to greater tissue velocities with atrial contraction. Peak LV longitudinal strain was lower in AS users (AS ?14.2 ± 2.7 % vs. NAS ?16.6 ± 1.9 %; p < 0.05). There was no evidence of focal fibrosis in any participant.

Conclusions

AS use was associated with significant LV hypertrophy, albeit in-line with greater fat-free mass, reduced LV strain, diastolic function, and reduced RV ejection fraction in male bodybuilders. There was, however, no evidence of focal fibrosis in any AS user.  相似文献
