Abstract
OBJECTIVES Assess differences in perceived health status among individuals receiving colonoscopy screening based on smoking status. STUDY DESIGN Cross-sectional data were collected as part of a larger study investigating whether verbal and non-verbal communication and behaviors of gastroenterologists and nurses. METHOD Data for this study were collected between 2011 and 2013 among receiving colonoscopy screenings. Data were collected as part of a study assessing patients (n = 1785) undergoing colonoscopy screenings about their expectations, concerns, understanding of the procedure, and perceived health status. Differences between current, former and never smokers were analyzed using a one-way between subjects ANOVA, with a Scheffe post hoc. RESULTS Post hoc analyses revealed that current smokers were significantly different from former or never smokers on the following variables: days their physical health was not good, days their mental health was not good, days health influenced their activities, days pain influenced their ability to perform activities, perceived general health, and current anxiety. CONCLUSION This study looked at perceived health among individuals receiving colonoscopy screening by on smoking status, a relevant population based on the recent Surgeon Generals link. Former smokers reported similar health status across all variables as never smokers, suggesting the effect of quitting smoking on self-perceived health. With this link, tailored smoking cessation messages to smokers receiving colonoscopy screenings may be an excellent vantage point for a smoking cessation intervention.

Abstract
The severe shortage of donor hearts limits the availability of transplantation for the growing population of patients with end-stage heart disease. We examined national trends in donor heart acceptance for transplant. OPTN data were analyzed for all potential adult cardiac organ donors between 1995 and 2010. Donor heart disposition was categorized as transplanted, declined for transplant or other. We studied changes in the probability of donor heart acceptance according to demographic and clinical characteristics, nationwide and by UNOS region. Of 82 053 potential donor hearts, 34% were accepted and 48% were declined (18% used for other purposes). There was a significant decrease in donor heart acceptance from 44% in 1995 to 29% in 2006, and subsequent increase to 32% in 2010. Older donor age, female sex and medical co-morbidities predicted non-acceptance. Donor age and co-morbidities increased during the study period, with a concomitant decrease in acceptance of hearts from donors with undesirable characteristics. Overall, predictors of heart non-use were similar across UNOS regions, although utilization varied between regions. Regional variation suggests a potential to improve heart acceptance rates in under-performing regions, and supports research and policy efforts aimed at establishing evidence-based criteria for donor heart evaluation and acceptance for transplantation.

Abstract
PURPOSE Theoretical dose-response models offer the possibility to assess second cancer induction risks after external beam therapy. The parameters used in these models are determined with limited data from epidemiological studies. Risk estimations are thus associated with considerable uncertainties. This study aims at illustrating uncertainties when predicting the risk for organ-specific second cancers in the primary radiation field illustrated by choosing selected treatment plans for brain cancer patients. METHODS A widely used risk model was considered in this study. The uncertainties of the model parameters were estimated with reported data of second cancer incidences for various organs. Standard error propagation was then subsequently applied to assess the uncertainty in the risk model. Next, second cancer risks of five pediatric patients treated for cancer in the head and neck regions were calculated. For each case, treatment plans for proton and photon therapy were designed to estimate the uncertainties (a) in the lifetime attributable risk (LAR) for a given treatment modality and (b) when comparing risks of two different treatment modalities. RESULTS Uncertainties in excess of 100% of the risk were found for almost all organs considered. When applied to treatment plans, the calculated LAR values have uncertainties of the same magnitude. A comparison between cancer risks of different treatment modalities, however, does allow statistically significant conclusions. In the studied cases, the patient averaged LAR ratio of proton and photon treatments was 0.35, 0.56, and 0.59 for brain carcinoma, brain sarcoma, and bone sarcoma, respectively. Their corresponding uncertainties were estimated to be potentially below 5%, depending on uncertainties in dosimetry. CONCLUSIONS The uncertainty in the dose-response curve in cancer risk models makes it currently impractical to predict the risk for an individual external beam treatment. On the other hand, the ratio of absolute risks between two modalities is less sensitive to the uncertainties in the risk model and can provide statistically significant estimates.

Abstract
BACKGROUND Morphine stimulates angiogenesis and cancer progression in mice. We investigated whether morphine influences tumour onset, development, and animal model survival, and whether µ-opioid receptor (MOR), lymphangiogenesis, mast cell activation, and substance P (SP) are associated with the tumour-promoting effects of morphine. METHODS Transgenic mice with a rat C3(1) simian virus 40 large tumour antigen fusion gene which demonstrate the developmental spectrum of human infiltrating ductal breast carcinoma were used. Mice were treated at different ages with clinically relevant doses of morphine or phosphate-buffered saline to determine the effect on tumour development and progression, and on mouse survival. Tumours were analysed for MOR, angiogenesis, lymphangiogenesis, SP, and mast cell activation by immunofluorescent- or laser scanning confocal-microscopy. Cytokine and SP levels were determined by enzyme-linked immunosorbent assay. RESULTS Morphine did not influence tumour development when given before the onset of tumour appearance, but significantly promoted progression of established tumours, and reduced survival. MOR-immunoreactivity (ir) was observed in larger but not in smaller tumours. Morphine treatment resulted in increased tumour angiogenesis, peri-tumoural lymphangiogenesis, mast cell activation, and higher levels of cytokines and SP in tumours. SP-ir co-localized with mast cells and elsewhere in the tumours. CONCLUSIONS Morphine does not affect the onset of tumour development, but it promotes growth of existing tumours, and reduces overall survival in mice. MOR may be associated with morphine-induced cancer progression, resulting in shorter survival. Mast cell activation by morphine may contribute to increased cytokine and SP levels, leading to cancer progression and refractory pain.

Abstract
BACKGROUND Blastomyces dermatitidis infection of head and neck structures is a rare clinical entity. However, the potential for significant morbidity warrants clinical consideration and timely diagnosis. OBJECTIVE OF REVIEW To describe the clinical presentations, diagnostic challenges, and outcomes of otolaryngologic blastomycosis. SEARCH STRATEGY A literature search of the Pubmed and Ovid databases with the terms "blastomycosis AND. . . " followed by all terms related to anatomical regions of the head and neck. EVALUATION METHOD All publications which discussed pertinent otolaryngologic involvement from blastomycotic infections were evaluated. RESULTS AND CONCLUSION The larynx was the most commonly reported site of infection, followed by the oral cavity, neck, ear, nasal cavity/paranasal sinuses, and skull base/orbit/calvarium. Diagnosis of blastomycosis was almost universally delayed due to the resemblance of presentation to more common clinical entities, most notably squamous cell carcinoma. A substantial portion of cases (42%) presented without clinical or radiographic evidence of pulmonary infection. The initial diagnostic confusion often resulted in disease progression and trials of invasive therapies. Most patients experienced complete resolution of symptoms and lesions within months of initiation of proper antifungal medications. Permanent sequelae were relatively uncommon and related to the structures involved in the primary infection.

Abstract
Abstract
Introduction: Breast cancer-related pain significantly affects quality of life and is well-documented in developed countries. However, little is known about the extent of breast cancer-related pain in developing countries. A study at the National Cancer Institute of Vietnam reported that 44% of breast cancer patients experienced moderate to severe pain. However, this study did not include breast cancer survivors, and little is known about the prevalence of pain and its management in this patient population.
Objectives: Determine the prevalence of pain, adequacy of pain management, and barriers to care in breast cancer survivors in Vietnam.
Methods: We administered previously validated and published symptom assessment tools (the BPI and MDASI) to 160 unselected Vietnamese women diagnosed and treated for breast cancer in 2007. Here we present a preliminary description of the results for the first 40 breast cancer survivors enrolled in this study.
Results: The most frequently reported symptoms were pain (62.5%, with 40% reporting the pain as severe), memory loss (50%), numbness/tingling (50%), sleep disturbance (45%), and appetite loss (32.5%). Only 23% reported adequate symptom management, with the costs of treatment and the false belief that no treatments existed for the pain being frequently cited as barriers to care.
Discussion: Cancer-related pain is highly prevalent in breast cancer survivors treated at the largest cancer hospital in Vietnam. The majority of patients report inadequate management of pain, often attributable to costs and false beliefs regarding pain management. Initiatives aimed at patient education and improving accessibility to pain management could significantly improve the quality of life in this patient population.

Abstract
BACKGROUND Pain and renal dysfunction occur in sickle cell disease. Morphine used to treat pain also co-activates platelet-derived growth factor receptor-β (PDGFR-β), which can adversely affect renal disease. We examined the influence of morphine in mesangial cells in vitro and in mouse kidneys in vivo. METHODS > Mouse mesangial cells treated with 1 μM morphine in vitro or kidneys of transgenic homozygous or hemizygous sickle or control mice (n=3 for each), treated with morphine (0.75, 1.4, 2.14, 2.8, 3.6, and 4.3 mg kg(-1) day(-1) in two divided doses during the first, second, third, fourth, fifth, and sixth weeks, respectively), were used. Western blotting, bromylated deoxy uridine incorporation-based cell proliferation assay, reverse transcriptase-polymerase chain reaction, immunofluorescent microscopy, and blood/urine chemistry were used to analyse signalling, cell proliferation, opioid receptor (OP) expression, and renal function. RESULTS Morphine stimulated phosphorylation of PDGFR-β and mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) to the same extent as induced by platelet-derived growth factor-BB (PDGF-BB) and promoted a two-fold increase in mesangial cell proliferation. The PDGFR-β inhibitor, AG1296, OP antagonists, and silencing of μ- and κ-OP abrogated morphine-induced MAPK/ERK phosphorylation and proliferation by ~100%. Morphine treatment of transgenic mice resulted in phosphorylation of PDGFR-β, MAPK/ERK, and signal transducer and activator of transcription 3 (Stat3) in the kidneys. Morphine inhibited micturition and blood urea nitrogen (BUN) clearance and increased BUN and urinary protein in sickle mice. CONCLUSION Morphine stimulates mitogenic signalling leading to mesangial cell proliferation and promotes renal dysfunction in sickle mice.

Abstract
The term 'limb-girdle myasthenia' (LGM) was first used to describe three siblings with proximal limb weakness without oculobulbar involvement, but with EMG decrement and responsiveness to anticholinesterase medication. We report here that exome sequencing in the proband of this family revealed several sequence variations in genes linked to proximal limb weakness. However, the only mutations that cosegregated with disease were an intronic IVS7-8A>G mutation and the previously reported 3'-UTR c.*22C>A mutation in GFPT1, a gene linked to LGM. A minigene assay showed that IVS7-8A>G activates an alternative splice acceptor that results in retention of the last seven nucleotides of intron 7 and a frameshift leading to a termination codon 13 nucleotides downstream from the new splice site. An anconeus muscle biopsy revealed mild reduction of the axon terminal size and postsynaptic fold simplification. The amplitudes of miniature endplate potentials and quantal release were also diminished. The DNA of the mildly affected father of the proband showed only the intronic mutation along with sequence variations in other genes potentially relevant to LGM. Thus, this study performed in the family originally described with LGM showed two GFPT1 untranslated mutations, which may cause disease by reducing GFPT1 expression and ultimately impairing protein glycosylation.

Abstract
Most of the French passengers who survived the shipwreck of the cruise ship Costa Concordia were repatriatedfrom Italy to Marseille, one of the stopovers of the cruise. The shipwreck happened during the nightof 13th-14th January 2012 and entailed the forced evacuation of 4195 passengers and crewmembers.Thirty-two persons died and 2 others are still reported missing. The massive and unexpected inflow of402 French citizens in the port of Marseille required the quick setting up of welcome facilities, not only tosolve logistical problems, but also to address psychological and sometimes even medical problems. ThePrehospital Psychological Emergency Service (CUMP) and the Prehospital Emergency Medical Service(SAMU) of Marseille examined 196 persons in total, and were able to avoid a great number of emergencyadmissions deemed necessary because of difficult psychological situations (death, missing or lost persons,acute stress). The objective of this report is to rapidly present the emergency committee as a whole andto describe in more detail the work that the CUMP accomplished during the 36 hours necessary to takecharge of the majority of the French passengers of the Costa Concordia.

Abstract
Prior studies have demonstrated associations between beta-adrenergic receptor (βAR) polymorphisms and left ventricular dysfunction-an important cause of allograft nonutilization for transplantation. We hypothesized that βAR polymorphisms predispose donor hearts to LV dysfunction after brain death. A total of 1043 organ donors managed from 2001-2006 were initially studied. The following βAR single nucleotide polymorphisms were genotyped: β1AR 1165C/G (Arg389Gly), β1AR 145A/G (Ser49Gly), β2AR 46G/A (Gly16Arg) and β2AR 79C/G (Gln27Glu). In multivariable regression analyses, the β2AR46 SNP was significantly associated with LV systolic dysfunction, with each minor allele additively decreasing the odds for LV ejection fraction <50%. The β1AR1165 and β2AR46 SNPs were associated with higher dopamine requirement during the donor management period: donors with the GG and AA genotypes had ORs of 2.64 (95% CI 1.52-4.57) and 2.70 (1.07-2.74) respectively for requiring >10 μg/kg/min of dopamine compared to those with the CC and GG genotypes. However, no significant associations were found between βAR SNPs and cardiac dysfunction in 364 donors managed from 2007-2008, perhaps due to changes in donor management, lack of power in this validation cohort, or the absence of a true association. βAR polymorphisms may be associated with cardiac dysfunction after brain death, but these relationships require further study in independent donor cohorts.

Abstract
The purpose of this study was to compare the amount of acetabular bone removed during hip resurfacing (HR) and cementless total hip replacement (THR), after controlling for the diameter of the patient’s native femoral head. Based on a power analysis, 64 consecutive patients (68 hips) undergoing HR or THR were prospectively enrolled in the study. The following data were recorded intra-operatively: the diameter of the native femoral head, the largest reamer used, the final size of the acetabular component, the size of the prosthetic femoral head and whether a decision was made to increase the size of the acetabular component in order to accommodate a larger prosthetic femoral head. Results were compared using two-sided, independent samples Student’s t-tests. A statistically significant difference was seen in the mean ratio of the size of the acetabular component to the diameter of the native femoral head (HR: 1.05 (sd 0.04) versus THR: 1.09 (sd 0.05); p < 0.001) and largest acetabular reamer used to the diameter of the native femoral head (HR: 1.03 (sd 0.04) versus THR: 1.09 (sd 0.05); p < 0.001). The ratios varied minimally when the groups were subdivided by gender, age and obesity. The decision to increase the size of the acetabular component to accommodate a larger femoral head occurred more often in the THR group (27% versus 9%). Despite the emphasis on avoiding damage to the femoral neck during HR, the ratio of the size of the acetabular component to the diameter of the native femoral head was larger in cementless THR than in HR.

Abstract
The aims of this study were to determine whether infants and toddlers with chronic lung disease of infancy (CLDI) have smaller airways and lower lung density compared with full-term healthy controls. Multi-slice computed tomography (CT) chest scans were obtained at elevated lung volumes during a brief respiratory pause in sedated infants and toddlers; 38 CLDI were compared with 39 full-term controls. For CLDI subjects, gestational age at birth ranged from 25 to 29 weeks. Airway size was measured for the trachea and the next three to four generations into the right lower lobe; lung volumes and tissue density were also measured. The relationship between airway size and airway generation differed between the CLDI and full-term groups; the sizes of the first and second airway generations were larger in the shorter CLDI than in the shorter full-term subjects. The increased size in the airways in the CLDI subjects was associated with increasing mechanical ventilation time in the neonatal period. CLDI subjects had a greater heterogeneity of lung density compared with full-term subjects. Our results indicate that quantitative analysis of multi-slice CT scans at elevated volumes provides important insights into the pulmonary pathology of infants and toddlers with CLDI.

Abstract
AIMS To assess health-related quality of life (HRQOL) after palliative radiotherapy for painful bone metastases using a palliative questionnaire (European Organization for Research and Treatment of Cancer QLQ-C15-PAL). MATERIALS AND METHODS Patients scheduled to receive palliative radiotherapy for painful bone metastases (n=178) completed the QLQ-C15-PAL questionnaire before treatment and at week 1, week 2, month 1 and month 2 after the first day of radiotherapy. A partial response (PR) or a complete response (CR) to radiotherapy was defined according to the International Consensus criteria. General linear regression was used to analyse changes in QOL in the entire cohort and within responders and non-responders to radiotherapy at all follow-up periods. RESULTS The overall radiotherapy response was 45% at week 1 (n=21) (41% PR, 4% CR), 62% at week 2 (n=28) (58% PR, 4% CR), 62% at month 1 (n=58) (60% PR, 2% CR) and 65% at month 2 (n=38) (60% PR, 5% CR). In general, a significant decrease in pain (P<0.0001), insomnia (P<0.0001) and constipation (P=0.004) was seen by month 1 after radiotherapy. In patients who responded to radiotherapy, overall QOL significantly improved by month 2 after radiotherapy (P=0.002). Radiotherapy responders also reported an improvement in emotional functioning together with a decrease in symptoms such as insomnia and constipation at month 1. No improvements were seen in any of the QLQ-C15-PAL scores for patients whose pain did not respond to radiotherapy. CONCLUSION Radiotherapy responders showed not only an improvement in pain, but also in HRQOL as assessed by QLQ-C15-PAL. As early as 1 week after radiotherapy for bone metastases, a pain relief response was reported by patients.

Abstract
AIMS To report pain and functional interference responses in patients radiated for painful spinal metastases, and to determine if location within the vertebral column or dose fractionation are associated with response. MATERIALS AND METHODS Patients treated with palliative radiotherapy for symptomatic spinal metastases from May 2003 to June 2005 were analysed. All patients completed the Brief Pain Inventory (BPI) assessment tool at 1, 2 and 3 months after radiotherapy. The pain response was determined using the International Bone Metastases Consensus response definitions. Given seven BPI functional interference items, a Bonferroni adjusted P value of less than 0.007 was considered significant. RESULTS One hundred and nine treated patients were assessed. About 50% of patients were treated with a single fraction of 8Gy. All pain scores and functional interference scores significantly decreased over time after radiotherapy. At 3 months, 64% of patients achieved a response. Mood was significantly improved for responders (P=0.003) and a trend in improvement was observed for general activity (P=0.01) and normal work (P=0.04). Breast and prostate primaries were more likely to achieve an early response as compared with a lung primary. Neither location within the vertebral column or radiotherapy dose fractionation independently predicted for pain or functional interference responses. CONCLUSION Conventional radiotherapy with 8Gy in a single fraction for spine metastases resulted in effective palliation of pain at 3 months and had a positive effect on a patient's mood. Location within the spine was not a predictive factor.

Abstract
BACKGROUND Health disparities and the high prevalence of cardiovascular disease continue to be perplexing worldwide health challenges. This study addresses the possibility that genetic differences affecting the biology of the vascular endothelium could be a factor contributing to the increased burden of cardiovascular disease and cancer among African Americans (AA) compared to Caucasian Americans (CA). METHODS From self-identified, healthy, 20 to 29-year-old AA (n = 21) and CA (n = 17), we established cultures of blood outgrowth endothelial cells (BOEC) and applied microarray profiling. BOEC have never been exposed to in vivo influences, and their gene expression reflects culture conditions (meticulously controlled) and donor genetics. Significance Analysis of Microarray identified differential expression of single genes. Gene Set Enrichment Analysis examined expression of pre-determined gene sets that survey nine biological systems relevant to endothelial biology. RESULTS At the highly stringent threshold of False Discovery Rate (FDR) = 0, 31 single genes were differentially expressed in AA. PSPH exhibited the greatest fold-change (AA > CA), but this was entirely accounted for by a homolog (PSPHL) hidden within the PSPH probe set. Among other significantly different genes were: for AA > CA, SOS1, AMFR, FGFR3; and for AA < CA, ARVCF, BIN3, EIF4B. Many more (221 transcripts for 204 genes) were differentially expressed at the less stringent threshold of FDR <.05. Using the biological systems approach, we identified shear response biology as being significantly different for AA versus CA, showing an apparent tonic increase of expression (AA > CA) for 46/157 genes within that system. CONCLUSIONS Many of the genes implicated here have substantial roles in endothelial biology. Shear stress response, a critical regulator of endothelial function and vascular homeostasis, may be different between AA and CA. These results potentially have direct implications for the role of endothelial cells in vascular disease (hypertension, stroke) and cancer (via angiogenesis). Also, they are consistent with our over-arching hypothesis that genetic influences stemming from ancestral continent-of-origin could impact upon endothelial cell biology and thereby contribute to disparity of vascular-related disease burden among AA. The method used here could be productively employed to bridge the gap between information from structural genomics (for example, disease association) and cell function and pathophysiology.

Abstract
OBJECTIVE Liver transplantation (LT) is the treatment of choice for end-stage liver disease. The required immunosuppression increases the risk for developing malignancies. Some viruses play a crucial role. Data on neoplasms of the colon, rectum and anus in LT are limited. METHOD A retrospective evaluation of the incidence and clinical course of colorectal and anal malignancies and colonic polyps in a series of 467 consecutive LTs in 402 individuals between 1998 and 2001 was performed. Standard immunosuppression included Tacrolimus, Mycophenolic acid and steroids. RESULTS During a median follow up of 5.2 years, three colon adenocarcinomas, one EBV associated cecal posttransplant lymphoproliferative tumour and two HPV associated anal tumours were identified. Pre-LT colonoscopy was performed in 161 patients (40%), and of 153 evaluable individuals, 53 (34.9%) had polyps. Colonoscopy was performed in 186 patients (46.3%) median 14.8 (range 0.2-77.8) months post-LT and 55 (29.3%) had polyps. Post-LT adenomatous polyps were detected in 47.3% of patients with pre-LT polyps vs 6.7% of patients without pre-LT polyps (P < 0.001). Patients with alcoholic liver disease had a significantly higher rate of adenoma formation (50.0% vs 11.1%, P < 0.001). No patient died from colorectal/anal malignancy. CONCLUSION The incidence of metachronous and new polyp formation in our study is similar to people who are not immunocompromised, but subgroups are at increased risk. Viral-associated malignancies, including post-transplant lymphoproliferative disorders and anal cancer, are important entities in the LT population suggesting that complete screening of the colon, rectum and anus including pre-LT and post-LT colonoscopy should be utilized.

Abstract
Syncope is a syndrome characterized by a relatively sudden, temporary and self-terminating loss of consciousness; the causes may vary, but they have in common a temporary inadequacy of cerebral nutrient flow, usually due to a fall in systemic arterial pressure. However, while syncope is a common problem, it is only one explanation for episodic transient loss of consciousness (TLOC). Consequently, diagnostic evaluation should start with a broad consideration of real or seemingly real TLOC. Among those patients in whom TLOC is deemed to be due to ''true syncope'', the focus may then reasonably turn to assessing the various possible causes; in this regard, the neurally-mediated syncope syndromes are among the most frequently encountered. There are three common variations: vasovagal syncope (often termed the ''common'' faint), carotid sinus syndrome, and the so-called ''situational faints''. Defining whether the cause is due to a neurally-mediated reflex relies heavily on careful history taking and selected testing (e.g., tilt-test, carotid massage). These steps are important. Despite the fact that neurally-mediated faints are usually relatively benign from a mortality perspective, they are nevertheless only infrequently an isolated event; neurally-mediated syncope tends to recur, and physical injury resulting from falls or accidents, diminished quality-of-life, and possible restriction from employment or avocation are real concerns. Consequently, defining the specific form and developing an effective treatment strategy are crucial. In every case the goal should be to determine the cause of syncope with sufficient confidence to provide patients and family members with a reliable assessment of prognosis, recurrence risk, and treatment options.
