Abstract
Abstract
BACKGROUND: More than two-thirds of children who present to the emergency department (ED) complain of pain. It is well known that children’s pain is poorly managed in the ED compared to their adult counterparts. With respect to analgesic administration in the ED, discrepancies exist between physician self-report and institutional audit. Patient refusal of analgesia is a likely explanation. There is good evidence that misconceptions and fears about analgesia in children are common among caregivers and may contribute to withholding pain medication. To date, no study has surveyed caregivers presenting the the ED to assess frequency of analgesic administration and reasons for withholding analgesia. We hypothesize that there will be a significant proportion of care-givers and patients that refuse pain medication in the ED. We also hypothesize that there will be a wide range of reasons for refusal. The insight we gain from this study will help nurses, clinical educators, and physicians provide the appropriate information to parents in an effort to target misconceptions and allay fears.
OBJECTIVES: Our objectives were to characterize the degree of care-giver and patient provision of analgesia prior to arrival, refusal of analgesia in the ED, and reasons behind their decision-making process. We hope to identify specific misconceptions, attitudes, or beliefs that impair the optimal provision of analgesia to children in the ED.
DESIGN/METHODS: A novel survey was designed by a focus group using an iterative approach and implemented over a 16-week period across two Canadian tertiary care paediatric EDs. We included a consecutive sample of caregivers of children aged 4-17 years with an acutely painful condition (headache, abdominal pain, injury, otitis, pharyngitis). Caregivers were asked to answer questions covering five domains: (i) demographics, (ii) analgesia prior to arrival (iii) analgesia offered in the ED and reasons for refusal, (iv) perceptions of analgesia, and (v) caregiver satisfaction at discharge. Children were asked to rate their pain on arrival and at discharge. The primary outcome was the frequency of caregiver provision of analgesia prior to arrival and the proportion of caregivers who accept the offer of analgesia offered in the ED.
RESULTS: Three hundred forty-four caregivers completed the survey. The majority were female (269/339, 79%), aged 36 years or older (256/340, 75%) with a post-secondary education (237/336, 71%). Most (309/339, 91%) reported being able to “tell when their child was in pain”. All respondents rated their child’s maximal pain related to the presenting condition as at least a 6/10. With regards to the primary outcome, 229/338 (68%) of caregivers reported that they did not treat their child’s pain prior to arrival in the ED. Of those who did treat their child’s pain, ibuprofen was the most commonly used analgesic (77/112, 69%). The most common reasons for withholding analgesia was a lack of time (80/210, 38%), fear of masking seriousness of child’s condition (49/210, 23%), fear of masking signs and symptoms (48/210, 23%), and a lack of analgesia at home (47/210, 22%). Analgesia was offered to 186/344 (45%) of children in the ED and the majority of caregivers 157/186 (84%) accepted the offer. The most common reason for not accepting analgesia in the ED was child refusal (15/20, 75%). Most, 231/338 (68%) of caregivers felt that their child’s pain was managed well in the ED.
CONCLUSION: This survey of caregiver perceptions surrounding analgesia for children with acutely painful conditions presenting to the pae-diatric ED suggests that most do not treat their child’s pain prior to arrival, despite high levels of pain. Misconceptions surrounding analgesia prior to arrival are common. Despite this, most caregivers accepted analgesia in the ED. Our results suggest that educational strategies should be directed at caregiver awareness of the impact of pain on children and the need for prompt analgesic therapy, even when an ED visit is planned.

Abstract
BACKGROUND AND PURPOSE A number of parameters derived from dynamic contrast-enhanced MR imaging and separate histologic features have been identified as potential prognosticators in high-grade glioma. This study evaluated the relationships between dynamic contrast-enhanced MRI-derived parameters and histologic features in glioblastoma multiforme. MATERIALS AND METHODS Twenty-eight patients with newly presenting glioblastoma multiforme underwent preoperative imaging (conventional imaging and T1 dynamic contrast-enhanced MRI). Parametric maps of the initial area under the contrast agent concentration curve, contrast transfer coefficient, estimate of volume of the extravascular extracellular space, and estimate of blood plasma volume were generated, and the enhancing fraction was calculated. Surgical specimens were used to assess subtype and were graded (World Health Organization classification system) and were assessed for necrosis, cell density, cellular atypia, mitotic activity, and overall vascularity scores. Quantitative assessment of endothelial surface area, vascular surface area, and a vascular profile count were made by using CD34 immunostaining. The relationships between MR imaging parameters and histopathologic features were examined. RESULTS High values of contrast transfer coefficient were associated with the presence of frank necrosis (P = .005). High values of the estimate of volume of the extravascular extracellular space were associated with a fibrillary histologic pattern (P < .01) and with increased mitotic activity (P < .05). No relationship was found between mitotic activity and histologic pattern, suggesting that the correlation between the estimate of volume of the extravascular extracellular space and mitotic activity was independent of the histologic pattern. CONCLUSIONS A correlation between the estimate of volume of the extravascular extracellular space and mitotic activity is reported. Further work is warranted to establish how dynamic contrast-enhanced MRI parameters relate to more quantitative histologic measurements, including markers of proliferation and measures of vascular endothelial growth factor expression.

Abstract
The authors report a field study that investigated the canine parvovirus (CPV) strains present in dogs that developed the disease after being vaccinated. Faecal samples of 78 dogs that have been vaccinated against CPV and later presented with clinical signs suspected of parvovirus infection were used. Fifty (64.1 per cent) samples tested positive by PCR for CPV. No CPV vaccine type was detected. The disease by CPV-2b occurred in older and female dogs when compared with that by CPV-2c. The clinical signs presented by infected dogs were similar when any of both variants were involved. In most cases of disease, the resulting infection by field variants occurred shortly after CPV vaccination. Two dogs that had been subjected to a complete vaccination schedule and presented with clinical signs after 10 days of vaccination, had the CPV-2c variant associated. The phylogenetic studies showed a close relationship of the isolates in vaccinated dogs to European field strains. Despite the limited sample size in this study, the findings point to the significance of the continuous molecular typing of the virus as a tool to monitor the prevalent circulating CPV strains and access the efficacy of current vaccines. Adjustments on the vaccine types to be used may have to be evaluated again according to each epidemiological situation in order to achieve the dog's optimal immune protection against CPV.

Abstract
THEORY Although medical students begin medical school with better mental health than their peers, during medical school students have a higher prevalence of psychological distress. Medical students often do not seek help for mental health concerns. The use of approach coping strategies and social support has been shown in other populations to be related to mental health resiliency. HYPOTHESES The rates of depression and burnout in this medical student population are expected to be high, with the majority not seeking help for their psychological distress in accordance with studies of medical students across the nation. Perceptions of stigma are hypothesized to be a potential source of this lack of care-seeking behavior. Approach coping strategies and social support are speculated to have an inverse relationship with the prevalence of depression and burnout in the medical student population. METHOD Validated measures of depression and burnout along with items pertaining to diagnosis and treatment of mental health issues, specific coping strategies used during stressful times, and perceptions of social support were used in a cross-sectional study of students at the University of North Dakota School of Medicine and Health Sciences (UND SMHS). RESULTS The overall survey response rate was 64%. Seventeen percent had moderate to severe depression, and 49% had burnout. Of depressed respondents, 81% were undiagnosed. When asked why depression develops, 23% responded that it was due to an inability to cope. A significantly greater risk of depression was associated with inadequate support from family and friends (p = .002), fellow medical students (p = .01), and the UND SMHS (p = .003). Greater use of approach-oriented coping strategies than avoidant-oriented strategies was associated with significantly decreased risk of burnout (p = .02) and was inversely correlated with depression (rs = -0.27, n = 153, p = .001). CONCLUSIONS This study outlines associations among approach-oriented coping strategies, social support, and resiliency to mental health issues among medical students. This study also supports the existing literature that stigma regarding mental health issues is present in the medical community. Further multi-institutional, longitudinal research to delineate whether interventions that promote approach coping style and utilization of social support lead to decreased rates of mental health issues is necessary. The development of these interventions will need to be a multifaceted approach that includes promotion of care-taking behaviors but also focuses on institutional cultural change in order to empower students to participate in these resiliency strategies.

Abstract
Selection for lower somatic cell count has been included in the breeding objectives of several countries in order to increase resistance to mastitis. Genetic parameters of somatic cell scores (SCS) were estimated from the first lactation test day records of Brazilian Holstein cows using random-regression models with Legendre polynomials (LP) of the order 3-5. Data consisted of 87,711 TD produced by 10,084 cows, sired by 619 bulls calved from 1993 to 2007. Heritability estimates varied from 0.06 to 0.14 and decreased from the beginning of the lactation up to 60 days in milk (DIM) and increased thereafter to the end of lactation. Genetic correlations between adjacent DIM were very high (>0.83) but decreased to negative values, obtained with LP of order four, between DIM in the extremes of lactation. Despite the favorable trend, genetic changes in SCS were not significant and did not differ among LP. There was little benefit of fitting an LP of an order >3 to model animal genetic and permanent environment effects for SCS. Estimates of variance components found in this study may be used for breeding value estimation for SCS and selection for mastitis resistance in Holstein cattle in Brazil.

Abstract
Diffuse alveolar hemorrhage (DAH) is a syndrome caused by different mechanisms, including capillary stress failure, diffuse alveolar damage, and capillaritis. Capillaritis is the most common cause and is often associated with systemic autoimmune disorders, most commonly antineutrophilic cytoplasmic antibody-associated vasculitis. The occurrence of DAH with underlying pulmonary capillaritis but without clinical or serologic findings of an associated underlying systemic disorder is known as isolated pauciimmune pulmonary capillaritis (IPPC), and only eight cases have been described in the literature. The mainstay of treatment of this rare condition has been cyclophosphamide and glucocorticoids. When cases are unresponsive to cyclophosphamide, there is no known alternative treatment. Herein, we describe a case of IPPC that failed cyclophosphamide treatment with recurrent DAH. Rituximab therapy was then initiated with no further evidence of recurrence. This case report suggests that rituximab could be considered an alternative therapy to induce remission in patients with IPPC.

Abstract
The increasing incidence of rare mastitis-causing pathogens has urged the implementation of fast and efficient diagnostic and control measures. Prototheca algae are known to be associated with diseases in humans and animals. In the latter, the most prevalent form of protothecosis is bovine mastitis with Prototheca zopfii and Prototheca blaschkeae representing the most common pathogenic species. These nonphotosynthetic and colorless green algae are ubiquitous in different environments and are widely resistant against harmful conditions and antimicrobials. Hence, the association of Prototheca with bovine mastitis represents a herd problem, requiring fast and easy identification of the infectious agent. The purpose of this study was to develop a reliable and rapid method, based on the internal transcribed spacer (ITS) sequences of ribosomal DNA, for molecular identification and discrimination between P. zopfii and P. blaschkeae in bovine mastitic milk. The complete ITS sequences of 32 Prototheca isolates showed substantial interspecies but moderate intraspecies variability facilitating the design of species-specific PCR amplification primers. The species-specific PCR was successfully applied to the identification of P. zopfii and P. blaschkeae directly from milk samples. The intraspecific ITS phylogeny was compared for each species with the geographical distribution of the respective Prototheca isolates, but no significant correlation was found.

Abstract
OBJECTIVES The impact of Type 2 diabetes mellitus (T2DM) on health-related quality-of-life (HRQoL) is complex due to the burden of disease, lifelong treatment requirements, and comorbidities. This study aimed to capture UK societal utility values for health states associated with T2DM and treatment-related adverse events (AEs) to assess the burden of the disease and common AEs. METHODS Nine health state descriptions were developed (from a literature review and patient and clinician qualitative input) depicting the burden associated with T2DM and treatment-related AEs. These were mild/moderate urinary tract infection (UTI); severe UTI; mycotic infection; moderate hypoglycemic events; severe hypoglycemic events; fear of hypoglycemia; gastrointestinal symptoms; and hypovolemic events. Members of the UK general public (n = 100) valued these states using the time trade-off (TTO) methodology to elicit utility values (between 0 = dead, 1 = full health). Regression analysis was conducted to understand the influence of age and gender. RESULTS All treatment-related AEs were found to have a significant effect on utility. From the T2DM baseline state (0.92), the experience of AEs was associated with the following disutility: T2DM with hypovolemic events (0.08); T2DM with mild/moderate UTIs (0.09); T2DM with moderate hypoglycemic events (0.11); T2DM with severe hypoglycemic events (0.15); T2DM with fear of hypoglycemia (0.15); T2DM with severe UTIs (0.19); T2DM with GI symptoms (0.24); and T2DM with mycotic infection (0.25); Males consistently scored the states with significantly lower utility values, but no significant age effects emerged. CONCLUSIONS Findings suggest that adverse events in T2DM can be a burden for some individuals. The study indicates the potential importance of including information regarding AEs in economic evaluations. Although some states were rated severely in terms of utility; in reality, many of these only last a few days, therefore having a minimal quality-adjusted life year (QALY) impact.

Abstract
It is unclear whether physicians and patients have similar concerns and preferences when considering benefit and risks of aspirin and antifibrinolytic therapy for cardiac surgery. We surveyed both groups to ascertain their perceptions and preferences for treatment in this setting. Both preoperative and postoperative cardiac surgical patients and the physician craft groups caring for them (cardiology, surgery, anaesthesia/critical care), were provided with estimates of benefits and risks of aspirin and antifibrinolytic therapy. All study participants were asked to stipulate the minimal absolute risk reduction required for them to agree to such therapy. When compared with the cardiac surgical patients they treat, physicians required a smaller thrombotic risk reduction with aspirin whilst accepting its known increased risk of bleeding. This was significantly different in a high-risk stroke setting (incidence 5%) where the required relative risk reduction with aspirin use for physicians was 20% versus patients 40% (P <0.001); and for myocardial infarction, physicians 20% versus patients 36% (P=0.051). For antifibrinolytic therapy, the tolerated increased relative risk of stroke for physicians was 20% versus patients 10% (P=0.004), and for myocardial infarction, physicians 16.7% versus patients 4.2% (P <0.001). The three physician craft groups had comparable tolerances of thrombotic risk. Patient and physician preferences for perioperative aspirin and antifibrinolytic therapy sometimes differ based on risk benefit analysis.

Abstract
Freezability of equine semen may be influenced by microorganism population of semen. The objective of this study was to verify the effect of single-layer density gradient centrifugation (SLC) of fresh semen before cryopreservation on semen's microbial load (ML) and sperm cells kinetics after freezing-thawing. For that, one ejaculate was collected from 20 healthy stallions and split into control (C) samples (cryopreserved without previous SLC) and SLC samples (subjected to SLC). Semen cryopreservation was performed according to the same protocol in both groups. Microbial load of each microorganism species and total microbial load (TML) expressed in colony-forming units (CFU/mL) as well as frozen-thawed sperm kinetics were assessed in both groups. Additional analysis of the TML was performed, subdividing the frozen-thawed samples in "suitable" (total motility ≥ 30%) and "unsuitable" (total motility < 30%) semen for freezing programs, and comparing the C and SLC groups within these subpopulations. After thawing, SLC samples had less (P < 0.05) TML (88.65 × 10(2) ± 83.8 × 10(2) CFU/mL) than C samples (155.69 × 10(2) ± 48.85 × 10(2) CFU/mL), mainly due to a reduction of Enterococcus spp. and Bacillus spp. A relationship between post-thaw motility and SLC effect on ML was noted, as only in samples with more than 30% total motility was ML reduced (P < 0.05) by SLC (from 51.33 × 10(2) ± 33.26 × 10(2) CFU/mL to 26.68 × 10(2) ± 12.39 × 10(2) CFU/mL in "suitable" frozen-thawed semen vs. 240.90 × 10(2) ± 498.20 × 10(2) to 139.30 × 10(2) ± 290.30 × 10(2) CFU/mL in "unsuitable" frozen-thawed semen). The effect of SLC on kinetics of frozen-thawed sperm cells was negligible.

Effect of breeding activity on the microflora of the external genitalia and in the semen of stallions, and the relationship between micro-organisms on the skin and on the external genitalia. Reprod Domest Anim 2014; 49:926-33.

Abstract
A possible role of breeding activities in the composition of the microbial population in stallions' external genitalia (EG) and the relationship between micro-organisms colonizing the skin of the abdomen and the ones colonizing the EG have not been studied. In experiment 1, EG microbiological samples were collected from 41 stallions used for both natural cover and semen collection (BST) and from 18 non-breeding stallions (NBST). A higher (p < 0.05) frequency of isolation of potentially pathogenic species was found for BST. Age did not influence number of micro-organism species isolated both in BST and NBST. In experiment 2, the microbial content of the EG and semen was compared in 23 BST. Most micro-organisms isolated from the EG were present in semen, albeit with a numerically lower prevalence. In 7 stallions, six microbial species isolated from semen were absent from the EG cultures, suggesting contamination by the operator. In experiment 3, a numerically higher number of micro-organism species was isolated from the EG of 31 stallions, than from their skin of the ventral abdomen in contact with the penis or from the skin of the thorax. With the sole exception of Escherichia coli, potentially pathogenic bacteria were only isolated from the EG but not from the skin. Results suggest that breeding activity increased the number of species colonizing the EG; most species isolated from the EG were also found in semen even if with a lower frequency, and additional semen contamination seemed to occur during its manipulation. Many micro-organism species of the skin were also isolated from the penis, but independently of being or not in contact with the penis, skin did not seem to provide an adequate environment for the growth of potentially pathogenic bacteria that were isolated from EG, with the sole exception for E. coli.

Abstract
OBJECTIVE Music therapy is an innovative approach to support people with severe mental illness (SMI). The aim of the study was to determine whether group music therapy (GMT) positively impacted on quality of life (QoL), social enrichment, self-esteem, spirituality and psychiatric symptoms of participants with SMI and how they experienced the intervention. METHOD The primary outcome was QoL; secondary measures assessed social enrichment, self-esteem, spirituality and psychiatric symptoms. The 13-week intervention comprised singing familiar songs and composing original songs recorded in a professional studio. Qualitative data were generated from focus group interviews and song lyric analysis. RESULTS Ninety-nine adults (57 female) were recruited, with an initial cohort (n = 75) randomized to either: weekly GMT followed by standard care (SC) or SC followed by GMT. Crossover occurred after 13 weeks. Measures were conducted at baseline, 13, 26 and 39 weeks. A second cohort (n = 24) could not be randomized and were assigned to GMT followed by SC. Intention-to-treat analysis showed a significant difference between GMT and SC on QoL and spirituality. This was robust to different assumptions about missing data (listwise deletion, last observation carried forward or multiple imputation). Per-protocol analysis suggested greater benefit for those receiving more sessions. Focus group interview and song lyric analyses suggested that GMT was enjoyable; self-esteem was enhanced; participants appreciated therapists and peers; and although challenges were experienced, the programme was recommended to others. CONCLUSION Group music therapy may enhance QoL and spirituality of persons with SMI.
