Abstract
PURPOSE Few studies have compared follow-up-care models for adult survivors of childhood cancer (ASCCs), though choice of model could impact medical test adherence, and health-related quality of life (QOL). This study compared two follow-up-care models, cancer-center-based versus community-based, for ASCCs in Alberta, Canada, to determine which model would demonstrate greater ASCC adherence to guideline-recommended medical screening tests for late effects, QOL, physical symptoms, and adherence to yearly follow-up. METHODS ASCC discharged to a community model (over 15 years) and those with comparable birth years (1973-1993) currently followed in a cancer center model were recruited via direct contact or multimedia campaign. Chart review identified chemotherapeutic and radiation exposures, and required medical late effect screening tests. ASCCs also completed questionnaires assessing QOL, physical symptoms, and follow-up behavior. RESULTS One hundred fifty-six survivors participated (community (n = 86); cancer center (n = 70)). Primary analysis indicated that cancer center ASCCs guideline-recommended total test adherence percentage (Mdn = 85.4%) was significantly higher than the community model (Mdn = 29.2%, U = 3996.50, p < 0.0001). There was no significant difference in QOL for cancer center ASCCs (M = 83.85, SD = 20.55 versus M = 77.50, SD = 23.94; t (154) = 1.77, p = 0.078) compared to community-based ASCCs. Cancer center-based ASCCs endorsed from 0.4-7.1% fewer physical symptom clusters, and higher adherence to follow-up behavior in comparisons using effect sizes without p values. CONCLUSION This study highlights the cancer center model's superiority for adherence to exposure-based medical late effect screening guidelines, cancer-specific follow-up behaviors, and the reporting of fewer physical complaints in ASCCs. IMPLICATIONS FOR CANCER SURVIVORS ASCCs followed in a cancer center model likely benefit from earlier late-effects detection and opportunities for early intervention.

Abstract
It is now well recognized that cardiovascular events (CVE) occur quite commonly, both in the acute phase and in the long-term, in patients with community-acquired pneumonia (CAP). CVE have been noted in up to 30% of patients hospitalized with all-cause CAP. One systematic review and meta-analysis of hospitalized patients with all-cause CAP noted that the incidence rates for overall cardiac events were 17.7%, for incident heart failure were 14.1%, for acute coronary syndromes were 5.3% and for incident cardiac arrhythmias were 4.7%. In the case of pneumococcal CAP, almost 20% of patients studied had one or more of these cardiac events. Recent research has provided insights into the pathogenesis of the acute cardiac events occurring in pneumococcal infections. With respect to the former, key involvements of the major pneumococcal protein virulence factor, pneumolysin, are now well documented, whilst systemic platelet-driven neutrophil activation may also contribute. However, events involved in the pathogenesis of the long-term cardiovascular sequelae remain largely unexplored. Emerging evidence suggests that persistent antigenaemia may predispose to the development of a systemic pro-inflammatory/prothrombotic phenotype underpinning the risk of future cardiovascular events. The current manuscript briefly reviews the occurrence of cardiovascular events in patients with all-cause CAP, as well as in pneumococcal and influenza infections. It highlights the close interaction between influenza and pneumococcal pneumonia. It also includes a brief discussion of mechanisms of the acute cardiac events in CAP. However, the primary focus is on the prevalence, pathogenesis and prevention of the longer-term cardiac sequelae of severe pneumococcal disease, particularly in the context of persistent antigenaemia and associated inflammation.

Abstract
Abstract
Background
Metastatic breast cancer (MBC) is a heterogeneous disease, whose clinical course and prognosis may be unpredictable, creating significant uncertainty for patients and their families. Heterogeneity is breast cancer subtypes is now well recognized as a potential reason for treatment resistance. Sampling metastatic sites at the point of diagnosis or upon progression, when safe, is recommended to better guide therapy.
Purpose
This study evaluated patients currently undergoing treatment for MBC in the clinic to determine the clinical and translational significance of a metastatic sample.
Methods
Patients currently undergoing treatment for MBC at the Olivia Newton John Centre were identified. Data was collected on patient demographics, clinicopathological information, treatment and duration of response. Translational research tissue was collected, with consent, for DNA and RNA analysis.
Results
Between January 2017 and May 2018 111 patients were identified. The mean age of MBC diagnosis was 60 years (range 30-87), with a mean follow up time of 2.4 years (range 0.8-16). Fifteen patients died during the study period. Sixty-seven (60%) patients were initially treated for early breast cancer (EBC), with a median disease free interval (DFI) 4.7 years. Half (51%) these patients relapsed after five years.
At MBC diagnosis, multiple sites of disease were identified including bone, visceral, brain, nodal and skin/chest wall disease. Bone only disease was common (25%), whereas brain disease was rare overall (9%). Metastatic tissue was collected in 67 (60%) patients, where up to four different sites were biopsied. The most commonly biopsied site was bone (n=21), followed by soft tissue (n=20), chest wall/skin disease (n=12), liver (n=9), lung (n=8) and brain (n=8). Serous disease was collected in 16 patients, including pleural, pericardial, ascitic and cerebrospinal fluid.
Based on the EBC subtype (n=67), 70% had luminal disease, 19% had Her2 positive disease and 7% had TNBC. However, based on a metastatic biopsy (n=67), only 61% of patients had luminal disease, 21% had HER2 positive, and 18% had TNBC. Paired EBC and MBC samples were available in 48 patients, with significant change in breast cancer subtype demonstrated in 12 of these patients (25%). The most common change was a loss in ER staining, which included 6 patients from ER positive, HER2 negative to TNBC and three patients who became ER negative but remained HER2 positive. Molecular profiling was performed thus far on 8 samples at the single cell and bulk level. These results highlight a large level of inter- and intra-tumoral heterogeneity, and may result in a better understanding of the molecular pathways specifically deregulated in patients at the point of progression.
Conclusion
In this single institution series of patients with MBC, over half of the cohort underwent at least one metastatic biopsy. Strikingly, a quarter of patients demonstrated a change in their breast cancer subtype, which directly guided subsequent therapy. Metastatic tissue can provide vital information to inform treatment decisions, which may be guided by translational laboratories having access to fresh tissue at the point of metastatic diagnosis or disease progression.

Abstract
INTRODUCTION Historically, patients with unilateral high-grade vesicoureteral reflux (VUR) and contralateral low-grade or resolved VUR have been treated with bilateral intravesical ureteral reimplantation, which requires postoperative admission. If the high-grade VUR side is treated alone, then the contralateral side is at risk of developing recurrent or worsening VUR. Bilateral subureteric injection of dextronomer/hyaluronic acid (DHA) is another option that can be performed as an outpatient therapy, but a single injection is less effective for high-grade VUR. OBJECTIVE The safety and efficacy of an outpatient combination of open extravesical ureteral reimplantation (EVUR) and contralateral DHA injection were investigated. STUDY DESIGN A retrospective review of children who had concomitant EVUR and subureteric injection of DHA between January 2005 and December 2015 was performed. Exclusion criteria were diagnosis other than VUR, repeat procedures, and patients with no follow-up. Patient characteristics, postsurgical complications, and follow-up imaging were evaluated. Febrile urinary tract infection (fUTI) was defined as ≥50,000 Colony Forming Units (CFU) of an organism from clean-catch or catheterized urine and temperature ≥ 101.5 F. Clinical success is defined as no fUTI for 1 year after the initial operation. Univariate analyses were used to identify risk factors for treatment failure. RESULTS A total of 117 patients met inclusion criteria. Mean age at surgery was 6.0 years, and 85% were female. The mean pre-operative grade of VUR was 3.3 on the EVUR side and 0.6 on the contralateral side (42% resolved before treatment). Median follow-up was 12.2 months (interquartile range, 3.1-25.4). Sixteen patients (14%) had documented fUTI within 1 year, with a clinical success rate of 86%. Of these, five had a postoperative imaging showing resolution of VUR, increasing overall success to 91%. Postoperative fUTI was more common in patients with pre-operative bowel and bladder dysfunction (BBD) (P = 0.003), but this was not associated with a higher reoperation rate (P = 0.168). There were 11 total complications, with three grade 3 complications. DISCUSSION This study is the first to report safety and outcomes of EVUR and contralateral DHA injection for patients with high-grade VUR with contralateral low-grade or resolved VUR. It was shown that it is an effective and safe treatment that can be performed as an outpatient therapy. Limitations to this study include the retrospective design and the clinical definition of success that is used in a cohort of patients from across the mountain west region without routine postoperative voiding cystourethrogram. CONCLUSION Extravesical ureteral reimplantation and contralateral DHA injection can safely be performed as an outpatient therapy and are effective in the treatment of higher grade VUR with contralateral low-grade or resolved VUR. Treatment failure is more likely in patients with BBD.

Abstract
Obesity is a complex, chronic disease, frequently associated with multiple comorbidities. Its management is hampered by a lack of translation of evidence on chronicity and pathophysiology into clinical practice. Also, it is not well understood how to support effective provider-patient communication that adequately addresses patients' personal root causes and barriers and helps them feel capable to take action for their health. This study examined interpersonal processes during clinical consultations, their impacts, and outcomes with the aim to develop an approach to personalized obesity assessment and care planning. We used a qualitative, explorative design with 20 participants with obesity, sampling for maximum variation, to examine video-recorded consultations, patient interviews at three time points, provider interviews and patient journals. Analysis was grounded in a dialogic interactional perspective and found eight key processes that supported patients in making changes to improve health: compassion and listening; making sense of root causes and contextual factors in the patient's story; recognizing strengths; reframing misconceptions about obesity; focusing on whole-person health; action planning; fostering reflection and experimenting. Patient outcomes include activation, improved physical and psychological health. The proposed approach fosters emphatic care relationships and sensible care plans that support patients in making manageable changes to improve health.

Abstract
The occurrence of primary immunodeficiency diseases (PIDs) is low compared to that of immune-mediated disorders of autoimmune or atopic origin. However, progress in basic and clinical immunology over the past 3–4 decades has facilitated not only improved detection of PIDs, but has also created an awareness of an expanding spectrum of these conditions. Given that those who suffer from the most severe types of PID experience life-threatening microbial and viral infections usually from an early age, prompt recognition and definitive diagnosis enable implementation of appropriate prophylaxis and therapy, and, most importantly, corrective, immunorestoration using allogeneic haematopoietic stem cell transplantation. The purpose of the current review is therefore to alert family physicians to the presentation and types of PID that they may encounter in clinical practice, as well as to immunological screening procedures that can be undertaken to confirm or exclude the existence of the most common types of PID. This is followed by a consideration of prophylactic and therapeutic options and, finally, by a brief overview of gene therapy and gene-editing strategies that may offer alternatives to, or eventually replace, stem cell therapy.

Abstract
Lathosterolosis is a rare defect of cholesterol synthesis. Only four previous cases have been reported, two of whom were siblings. We report a fifth patient, with a relatively mild phenotype. He presented at 5 years of age with bilateral posterior cataracts, which were managed with lensectomies and intraocular lens implants. He also had learning difficulties, with a full-scale IQ of 64 at 11 years of age. His head circumference is between the 0.4th and 2nd centiles, and he has mild hypotonia and subtle dysmorphism (a high-arched palate, anteverted nostrils, long philtrum and clinodactyly of toes). The diagnosis was established after sequencing a panel of genes associated with cataracts, which revealed compound heterozygous SC5D mutations: c.479C>G p.(Pro160Arg) and c.630C>A p.(Asp210Glu). The plasma lathosterol concentration was markedly raised at 219.8 μmol/L (control range 0.53-16.0), confirming the diagnosis. The c.630C>A p.(Asp210Glu) mutation has been reported in one previous patient, who also had a relatively mild phenotype (Ho et al., JIMD Rep 12:129-134, 2014). The mutation leads to a relatively conservative amino acid substitution, consistent with some residual enzyme activity. Our patient's family did not notice any benefit from treatment with simvastatin. In summary, milder patients with lathosterolosis may present with learning difficulties, cataracts and very subtle dysmorphism. The diagnosis will be missed unless plasma sterols are analysed or relevant genes sequenced.

Abstract
Bovine spongiform encephalopathy (BSE) is caused by different prion strains that are discriminated by the molecular characteristics of the pathological prion protein. In 2011, Switzerland reported two presumptive cases of BSE in cattle with a prion protein phenotype different from previously described strains, and it was unclear whether these findings were related to a transmissible disease and have implications on animal and public health. In this study, brain tissues of these cases were inoculated into transgenic mice expressing the bovine prion protein (BoPrP-Tg110) and into cattle. Clinical and pathological investigations as well as molecular testing did not provide evidence for the presence of BSE in the Swiss cases after two passages in BoPrP-Tg110 mice and a challenge period of 3.5 years in cattle. This lack of disease transmission suggests that the Swiss 2011 cases were not affected by a prion disease and were unrelated to the feed-born BSE epidemic.

Abstract
Previous studies on the sterol fraction of the nonphotosynthetic marine diatom,Nitszchia alba, indicated the major sterol to be either brassicasterol (24R-methylcholesta-5,22-dien-3β-ol) or 22-dehydrocampesterol (24S-methylcholesta-5,22-dien-3β-ol) on the basis only of gas chromatographymass spectral analysis. The present studies using nuclear magnetic resonance, infrared, and gas chromatography-mass spectrometry on the free and bound sterol fractions isolated by preparative thin layer chromatography showed the presence in both fractions of a single sterol, with spectral and chromatographic properties identical with those reported for 24-methylenecholesterol (ergosta-5,24(28)-dien-3β-ol). This sterol may be the precursor of 24-methyl sterols found in diatoms. The bound sterol fraction was found to consist of a single compound identified as 24-methylenecholesterol sulfate. No sterol esters or sterol glycosides were detected.

Abstract
Adults with Autism Spectrum Conditions (ASC) experience marked difficulties in recognising the emotions of others and responding appropriately. The clinical characteristics of ASC mean that face to face or group interventions may not be appropriate for this clinical group. This article explores the potential of a new interactive technology, converting text to emotionally expressive speech, to improve emotion processing ability and attention to faces in adults with ASC. We demonstrate a method for generating a near-videorealistic avatar (XpressiveTalk), which can produce a video of a face uttering inputted text, in a large variety of emotional tones. We then demonstrate that general population adults can correctly recognize the emotions portrayed by XpressiveTalk. Adults with ASC are significantly less accurate than controls, but still above chance levels for inferring emotions from XpressiveTalk. Both groups are significantly more accurate when inferring sad emotions from XpressiveTalk compared to the original actress, and rate these expressions as significantly more preferred and realistic. The potential applications for XpressiveTalk as an assistive technology for adults with ASC is discussed.

Abstract
The primary objective of the current study was to investigate the potential of the pneumococcal toxin, pneumolysin (Ply), to activate neutrophil extracellular trap (NET) formation in vitro. Isolated human blood neutrophils were exposed to recombinant Ply (5-20 ng ml(-1) ) for 30-90 min at 37°C and NET formation measured using the following procedures to detect extracellular DNA: (i) flow cytometry using Vybrant® DyeCycle™ Ruby; (ii) spectrofluorimetry using the fluorophore, Sytox(®) Orange (5 μM); and (iii) NanoDrop(®) technology. These procedures were complemented by fluorescence microscopy using 4', 6-diamino-2-phenylindole (DAPI) (nuclear stain) in combination with anti-citrullinated histone monoclonal antibodies to visualize nets. Exposure of neutrophils to Ply resulted in relatively rapid (detected within 30-60 min), statistically significant (P < 0·05) dose- and time-related increases in the release of cellular DNA impregnated with both citrullinated histone and myeloperoxidase. Microscopy revealed that NETosis appeared to be restricted to a subpopulation of neutrophils, the numbers of NET-forming cells in the control and Ply-treated systems (10 and 20 ng ml(-1) ) were 4·3 (4·2), 14.3 (9·9) and 16·5 (7·5), respectively (n = 4, P < 0·0001 for comparison of the control with both Ply-treated systems). Ply-induced NETosis occurred in the setting of retention of cell viability, and apparent lack of involvement of reactive oxygen species and Toll-like receptor 4. In conclusion, Ply induces vital NETosis in human neutrophils, a process which may either contribute to host defence or worsen disease severity, depending on the intensity of the inflammatory response during pneumococcal infection.
