Abstract
Background: The University of British Columbia (UBC) Pharmacists Clinic (the Clinic) is a pharmacist-led patient care clinic serving as a practice site for experiential education in a team-based primary care practice. Given the unprecedented circumstances surrounding COVID-19, some pharmacy practice sites have permanently transitioned select experiential education activities to a virtual format. Currently, there is limited literature on teaching practices that are conducive to students' success in a virtual environment. Objective: To determine the factors that enable successful development of a virtual patient care practicum experience at a university clinic from the perspectives of student pharmacists and practice educators. Methods: A qualitative research methodology was used to gain the perspectives of student pharmacists, who did not have experience with virtual practicums, and practice educators, who had some experience with virtual practicums at the time of the study. Separate focus group interviews were conducted using a semi-structured approach and consisted of questions aimed at gathering insight into participant perspectives on virtual practicums. The focus group sessions were audio recorded with participant consent and transcribed. A thematic analysis was conducted to analyze the data. Results: Three pharmacist practice educators and three student pharmacists participated in their respective focus groups. Six major themes were developed based on the data: (1) technology optimization, (2) patient care related activities, (3) student-practice educator relationship, (4) student skill development, (5) student support, and (6) in-person vs virtual practicum preferences. Proposed strategies to mitigate the limitations of virtual practicums included setting communication guidelines, arranging enriching learning opportunities, and having reliable internet connection. Conclusion: The participants in this study provided insight on factors to support successful development and delivery of a virtual patient care practicum. The results from this study can be applied to other health disciplines and their approach to virtual practicums during and following the COVID-19 pandemic.

Abstract
Background Oral anticoagulation (OAC) is recommended for most individuals with atrial fibrillation (AF), including those who are frail. Based on previous literature, those who are frail may be less likely to be prescribed OAC, and up to one-third may receive an inappropriate dose if prescribed a direct oral anticoagulant (DOAC). The objectives of this study were to determine the proportion of frail ambulatory older adults with AF who are prescribed OAC, compare the rates of OAC use across the frailty spectrum, assess the appropriateness of DOAC dosing, and identify if frailty and geriatric syndromes impact OAC prescribing patterns. Methods Retrospective cross-sectional review of individuals with AF referred to an ambulatory clinic for older adults living with frailty and/or geriatric syndromes. Rockwood clinical frailty score of ≥4 was used to define frailty and DOAC appropriateness was assessed based on the Canadian Cardiovascular Society AF guidelines. Results Two hundred and ten participants were included. The mean age was 84 years, 49% were female and the median frailty score was 5. Of the 185 participants who were frail, 82% were prescribed an OAC (83% with frailty score of 4, 85% with a frailty score of 5, and 78% with a frailty score of 6). Of those prescribed a DOAC, 70% received a guideline-approved dose. Conclusions Over 80% of ambulatory older adults with frailty and AF were prescribed an OAC. However, of those prescribed a DOAC, 30% received an unapproved dose, suggesting more emphasis should be placed on initial and ongoing dosage selection.

Abstract
BACKGROUND Special Olympics International (SOI) has provided eye assessments at no cost to athletes participating in competitions through the Special Olympics Lions Clubs International Foundation Opening Eyes (OE) programme. Access to vision services is crucial given the high rates of eye abnormalities found in studies collected at OE programmes in other countries. As of 2022, no studies covering vision data have been published on SOI athletes specifically from the USA. Therefore, this multiple cross-sectional study hopes to investigate the vision profile of US athletes over three national games, detecting any changes in vision and ocular health outcomes over an 8-year period. METHODS Vision assessments were conducted in the US national games of 2010, 2014 and 2018. Demographic and clinical data from 1427 vision assessments were used in this study. Prevalence of vision and ocular health abnormalities were compared across national games. RESULTS In our cohort of 1427 assessments with athletes' mean age ± SD of 29.8 ± 11.5 years, 85.3% (n = 1170) had an abnormal vision result with at least one of the following findings: decreased visual acuity of 20/40 or worse (31.0%, n = 442), refractive error including myopia (52.8%, n = 754), hypermetropia (15.7%, n = 224), and astigmatism (35.0%, n = 499), ocular misalignment distant (16.2%, n = 224) or near (17.2%, n = 239), or ocular abnormality (19.1%, n = 273). CONCLUSIONS This study demonstrates the burden of vision defects and ocular disease in US SOI athletes over the past decade. While continued effort must be made to train eye providers in caring for patients with ID to increase eyecare accessibility outside of SOI, vision assessments at national games can continue providing opportunities for improved ocular health in children and adults with ID.

Abstract
Background: In recent years, Canadian health care professionals have observed an increase in vaccine refusal. The objective of this study is to review published literature and identify the main themes related to vaccine hesitancy and barriers to vaccination in Canadian adults and recent immigrants. Methods: A qualitative systematic review was performed. A comprehensive search of MEDLINE (1946 to January 2021) and EMBASE (1974 to January 2021) was conducted to identify existing literature that addressed the primary research question. Studies were eligible for inclusion if the study population involved 1) the general population, 2) Indigenous populations, 3) recent immigrants to Canada or 4) Canadian health care professionals. Results: Thirty-four studies were included with a focus on the general population (n = 22), health care professionals (n = 10) and recent immigrant populations (n = 2). The most frequently reported barriers were lack of vaccine information (41%), lack of access to vaccination (38%), fear of adverse reactions (38%), financial reasons (29%), lack of awareness of vaccine existence (29%), antivaccine sentiments (24%), notion that older adults do not need vaccination (18%), misconceptions on vaccine effectiveness (12%), potential sexual health promotion stigma (6%) and fear of needles (3%). Interpretation: Barriers to vaccination among Canadians and recent immigrants continue to be a challenge in the health care system. Conclusions: The greatest yield in improving vaccination rates is likely to come from supporting vaccine-hesitant individuals in shifting their thinking to greater vaccine acceptance. Pharmacists are well positioned to address vaccine hesitancy and involvement through education, facilitation and administration of vaccines. Can Pharm J (Ott) 2022;155:xx-xx.

Abstract
Background: Migraine and depression have a bi-directional, positive association. The likelihood of these conditions being comorbidities is high, thus, the possibility of concomitant use of an antidepressant and a triptan is also increased. Case Presentation: We present a case of a 39-year-old female with a history of migraine with aura and depression who had brief episodes of exacerbated depressive symptoms following oral administration of sumatriptan 100 mg daily as needed while taking various selective serotonin reuptake inhibitor (SSRI) and serotonin and norepinephrine reuptake inhibitor (SNRI) medications on different occasions. The patient experienced 30-minute episodes of sweating and subjective increase in temperature approximately 2-3 hours after administration of sumatriptan 100 mg. This was followed by a transient exacerbation of sadness described by the patient as unhappiness, hopelessness, and tearfulness, which lasted 1 to 2 hours. To date, there are no other published case reports that have described this particular presentation. Several studies have reported possible serotonin syndrome as a result of the combination. Current evidence and known pharmacological actions of SSRIs/SNRIs and triptans are not well-defined enough to explain how one can experience episodic worsening depression. Conclusion: This case illustrates that clinicians should consider other potential adverse effects of the combined use of triptans and SSRIs/SNRIs beyond serotonin syndrome.

Abstract
BACKGROUND The Cannabis Act, introduced in Canada in 2018, legalized the use of recreational cannabis. The impact of the announcement and implementation of this act on patient self-reporting of cannabis use has not been explored. OBJECTIVE The study objective was to determine if patient self-reported cannabis use increased after the announcement and implementation of legislative changes to legalize recreational cannabis. METHODS A repeated cross-sectional design was used for a retrospective chart review of patients seen at a pharmacist-led primary care clinic. A convenience sample of patient records was divided into 3 panels, corresponding with the preannouncement (November 1, 2013-October 4, 2015), postannouncement (October 5, 2015-October 16, 2018), and postimplementation (October 17, 2018-October 17, 2019) stages of the legalization of recreational cannabis. Search terms used included cannabis, marijuana, marihuana, recreational drugs, natur∗, medicinal, pot, joint, oil, butter, brownies, edibles, cannabin∗, THC, tetrahydro∗, sativa, and indica (∗ = string wild card). The frequency of reporting use and the number of queries related to cannabis were assessed. The analysis of variance test and Pearson correlation (chi-square) were used to compare the 3 panels. RESULTS A total of 298 patient charts were included in the analysis. One hundred, 99, and 99 patient charts corresponded with panels 1, 2, and 3, respectively. At each time point, 6%, 8%, and 14% of the patients reported cannabis use (P = 0.03). A statistically significant increase in topical oil use and a decrease in prescription tablet or capsule use between panels 1 and 3 (P = 0.036) were identified. CONCLUSION This study found an increase in self-reporting of cannabis use across the 3 consecutive panels. The change in the product formulations used may reflect the various products available. Frontline pharmacists are encouraged to initiate conversations regarding cannabis use as part of routine practice.

Abstract
Description of the problem: Development of evidence-based educational activities is needed to provide educators with the tools to aid learners in strengthening patient consultation skills in the primary care practice setting, an emerging area of practice in Canada.
Objective: The objective was to develop an educational activity to bring self-awareness to fourth year pharmacy student and pharmacy resident consultation skills and to determine learner perceptions of this educational activity, including identifying the key areas of skill development that learners found were positively impacted.
Description of the innovation: An innovative learning activity utilizing audio-video technology to enable recording and reviewing of learner-led patient consultations was developed and implemented within the University of British Columbia Pharmacists Clinic. Learners had the opportunity to lead 60-minute patient consultations. With patient and learner consent, patient consultations were recorded for learner viewing and self-assessment. Pharmacist preceptors supervised and assessed learner performance. Learners completed an online anonymous survey after the learning activity to evaluate its value.
Critical analysis: Between September 2018 and July 2019, eight pharmacy learners, consisting of student pharmacists (5) and post-graduate pharmacy residents (3) completed the learning activity and provided their feedback. The majority of learners (87.5%) felt the learning activity was beneficial to the development of patient consultation skills. Learners gained awareness of areas requiring improvement which included appropriate questioning, clear and concise language, time management and non-verbal habits.
Next steps: Adapting and modifying this learning activity to align with specific practice settings and learning objectives is feasible for other primary care practice sites offering experiential practicums.

Abstract
OBJECTIVES Preventing cardiovascular diseases (CVD) is a public health and policy priority, including for employers. A novel CVD risk management programme that included medication management was delivered by pharmacists to employees of a Canadian university. This qualitative study describes the experiences and perceptions of participants who received individual health consultations in this programme. METHODS A qualitative study design using free-text responses was adopted. Data (5658 words) came from evaluation surveys completed by 119 programme participants were iteratively coded and thematically analysed. KEY FINDINGS We identified four themes characterising participant experiences of pharmacist-led CVD prevention. Theme one was labelled self-efficacy because personalised health information and advice on CVD risk factor management empowered participants to make improvements for their health. Participants expressed a range of positive responses about the longer consultations, supportive communication and safe setting of their pharmacist-led encounters; hence, Theme two is labelled pharmacists' interpersonal skills. The wider context of the programme included a number of enabling factors (Theme three) that either supported or limited participant engagement in the programme. A number of changes to behaviour and health measures were identified and participant suggestions to expand and continue the programme further contributed to perceptions of positive programme impact (Theme four). CONCLUSIONS This study raises questions about how external resources and broader determinants might enable, or hinder, future programme success and sustainability. It also highlights the need for greater understanding and communication of the importance of primary prevention and the role of pharmacists in CVD risk reduction and workplace health promotion.

Abstract
Objective: To summarize available literature describing third-party payer reimbursement models for pharmacist-led preventive health services as part of workplace health initiatives. Methods: A combination of search terms related to pharmacists, preventive health, and third-party reimbursement were searched in MEDLINE, EMBASE, and PubMed. Included studies described community pharmacist-led cardiovascular and diabetes preventive health service to employees older than 18 years of age as part of a workplace health program with corresponding third-party reimbursement models. Programs that were reimbursed by government resources or studies lacking reimbursement model details were excluded. One reviewer performed level 1 screening and three reviewers analyzed included studies. Results: The search criteria yielded 863 results. Sixteen articles were reviewed after level 1 screening and 13 were ineligible and excluded. Three studies with varying quality of reporting were included. Reimbursement models varied from $40 USD for a 20-minute visit to $391 to $552 USD total per patient with an average of 6 visits per patient. Conclusion: There is a lack of quality literature describing third-party reimbursement models for pharmacist-led preventive health services, which hinders the ability to implement a standardized model. High quality studies evaluating the cost of reimbursing pharmacist-led cardiovascular preventive health services compared to the savings to the third-party payer should be performed to inform the standardization of payment models.

Abstract
Background: Burnout syndrome is well-documented among healthcare professionals across various practice settings. There has been recent expansion of Canadian pharmacists into team-based primary care and burnout in this setting has not been assessed. Our objective was to assess workplace burnout and to identify factors that play a role in perpetuating or diminishing it. Method: An online survey to assess burnout was developed using the Maslach Burnout Inventory (MBI) tool and questions regarding pharmacist background and practice. Invitations to complete the survey were sent to Canadian pharmacists working in team-based primary care settings on November 26, 2019 via a national primary healthcare listserv. Results: A total of 31/433 completed responses were collected. The main analysis focused on the personal accomplishment (PA) domain as it had an adequate response rate. The PA domain had a median score of 5.0 (95% CI 4.69-5.22). We compared medians of the PA domain across different groups of each categorical variable. We found that the number of years working in primary care settings was positively associated with a higher PA domain score (p= 0.029). Discussion: PA was higher in pharmacists who have been practicing in a primary care setting for longer; however, burnout rates could not be properly assessed due to the limited response rate. Conclusion: This is the first study to assess burnout among Canadian team-based primary care pharmacists. Personal accomplishment was higher in those who have been practicing in a primary care setting for longer. Future studies should consider alternate methods to evaluate burnout in this population.

Abstract
The COVID-19 pandemic has generated an unprecedented level of interest in, and uptake of, technology-enabled virtual health care delivery as clinicians seek ways to safely care for patients with physical distancing. This paper describes the UBC Pharmacists Clinic's technical systems and lessons learned using enabling technology and the provision of virtual patient care by pharmacists. Of 2036 scheduled appointments at the clinic in 2019, only 1.5% of initial appointments were conducted virtually which increased to 64% for follow-up appointments. Survey respondents (n = 18) indicated an overall high satisfaction with the format, quality of care delivery, ease of use and benefits to their overall health. Other reports indicate that the majority of patients would like the option to book appointments electronically, email their healthcare provider, and have telehealth visits, although a small minority (8%) have access to virtual modes of care. The Clinic team is bridging the technology gap to better align virtual service provision with patient preferences. Practical advice and information gained through experience are shared here. As the general population and health care providers become increasingly comfortable with video conferencing as a result of COVID-19, it is anticipated that requests for video appointments will increase, technological barriers will decrease and conditions will enable providers to increase their virtual care capabilities. Lessons learned at the Clinic have application to pharmacists in both out-patient and in-patient care settings.

Abstract
BACKGROUND Due to its eloquent location and potentially devastating neurological consequences, the management of brainstem cavernous malformations (CCMs) attracts considerable debate. There is currently a paucity of Level 1 evidence for their management. The aim of this literature review is to explore the current evidence on the risk-benefit profile of different management options. METHODS A systemic literature search, following the PRISMA algorithm was performed on publications between 2010 and 2018 using the Pubmed database, with the relevant keywords. Only English articles were included. Articles focusing on spinal CCMs and studies with less than 30 participants were excluded. RESULTS A total of 222 search results were reviewed and after removal of duplicates and screening of abstracts, 28 clinical papers comprising 30 or more brainstem CCM cases were included in the study. The heterogeneity of the publications precluded a formal meta-analysis of results. The general consensus is that for CCMs presenting with severe symptoms and/or multiple haemorrhages that reach an accessible pial surface, surgery is considered to be the gold-standard treatment, with some authors suggesting the optimal timing to be within two to six weeks of ictus. For those patients with multiple, deep-seated CCM related haemorrhages that do not reach the pial surface, stereotactic radiosurgery (SRS) can be considered. Conservative treatment is generally considered in incidental cases. Management of brainstem cavernomas of other categories still remains controversial. CONCLUSIONS Due to their highly eloquent location, brainstem CCMs are challenging lesions to manage. Management must be balanced by the risk-benefit profile and tailored to the individual patients and their treating clinicians. This review provides a comprehensive reference considering all treatment options and provides a basis for evidence-based patient counselling.

Abstract
Introduction Insertion of external ventricular drain (EVD) is a widely accepted, routinely performed procedure for treatment of hydrocephalus and raised intracranial pressure. The purpose of this study was to investigate whether a surgeon's experience affects the associated complication rate. Methods This retrospective study included all adult patients undergoing EVD insertion at a single centre between July 2013 and June 2015. Medical records were retrieved to obtain details on patient demographics, surgical indication, risk factors for infection and use of anticoagulants or antiplatelets. Surgeon experience, operative time, intraoperative antibiotic prophylaxis, need for revision surgery and EVD associated infection were examined. Information on catheter tip position and radiological evidence of intracranial haemorrhage was obtained from postoperative imaging. Results A total of 89 patients were included in the study. The overall infection, haemorrhage and revision rates were 4.8%, 7.8% and 13.0% respectively, with no significant difference among surgeons of different experience. The mean operating time for patients who developed an infection was 22 minutes while for those without an infection, it was 33 minutes (p=0.474). Anticoagulation/antiplatelet use did not appear to increase the rate of haemorrhage. The infection rate did not correlate with known risk factors (eg diabetes and steroids), operation start time (daytime vs out of hours) or duration of surgery although intraoperative (single dose) antibiotic prophylaxis seemed to reduce the infection rate. There was also a correlation between longer duration of catheterisation and increased risk of infection. Conclusions This is the first study demonstrating there is no significant difference in complication rates between surgeons of different experience. EVD insertion is a core neurosurgical skill and junior trainees should be trained to perform it.

Abstract
Abstract
Background
Hepatic resection and radiofrequency ablation (RFA) are treatment options for early-stage hepatocellular carcinoma (HCC). Whether tumour recurrence and long-term survival favour either treatment has not been established. This randomized trial aimed to test the hypothesis that RFA is superior to hepatic resection in terms of lower tumour recurrence rate and better long-term survival.
Methods
Patients with early-stage HCC (solitary tumour no larger than 5 cm; or no more than 3 tumours, each 3 cm or smaller) were randomized into hepatic resection and RFA groups. Demographic and clinical characteristics, and short- and long-term outcome measures were compared between groups. Primary and secondary outcome measures were overall tumour recurrence and survival respectively.
Results
Clinicopathological data were similar in the two groups, which each contained 109 patients. The RFA group had a shorter treatment duration, less blood loss and shorter hospital stay than the resection group. Mortality and morbidity rates were similar in the two groups. The overall tumour recurrence rate was similar in the resection and RFA groups (71·3 versus 81·7 per cent respectively). The 1-, 3-, 5- and 10-year overall survival rates were 94·5, 80·6, 66·5 and 47·6 per cent respectively in the resection group, compared with 95·4, 82·3, 66·4 and 41·8 per cent in the RFA group (P = 0·531). Corresponding disease-free survival rates were 74·1, 50·9, 41·5 and 31·9 per cent in the resection group, and 70·6, 46·6, 33·6 and 18·6 per cent in the RFA group (P = 0·072).
Conclusion
RFA for early-stage HCC is not superior to hepatic resection, in terms of tumour recurrence, overall survival and disease-free survival. Registration number: HKUCTR-10 (http://www.hkuctr.com).

Abstract
Pathogen buildup in vegetative planting material, termed seed degeneration, is a major problem in many low-income countries. When smallholder farmers use seed produced on-farm or acquired outside certified programs, it is often infected. We introduce a risk assessment framework for seed degeneration, evaluating the relative performance of individual and combined components of an integrated seed health strategy. The frequency distribution of management performance outcomes was evaluated for models incorporating biological and environmental heterogeneity, with the following results. (1) On-farm seed selection can perform as well as certified seed, if the rate of success in selecting healthy plants for seed production is high; (2) when choosing among within-season management strategies, external inoculum can determine the relative usefulness of 'incidence-altering management' (affecting the proportion of diseased plants/seeds) and 'rate-altering management' (affecting the rate of disease transmission in the field); (3) under severe disease scenarios, where it is difficult to implement management components at high levels of effectiveness, combining management components can be synergistic and keep seed degeneration below a threshold; (4) combining management components can also close the yield gap between average and worst-case scenarios. We also illustrate the potential for expert elicitation to provide parameter estimates when empirical data are unavailable. [Formula: see text] Copyright © 2017 The Author(s).

Abstract
Epidemiology has made significant contributions to plant pathology by elucidating the general principles underlying the development of disease epidemics. This has resulted in a greatly improved theoretical and empirical understanding of the dynamics of disease epidemics in time and space, predictions of disease outbreaks or the need for disease control in real-time basis, and tactical and strategic solutions to disease problems. Availability of high-resolution experimental data at multiple temporal and spatial scales has now provided a platform to test and validate theories on the spread of diseases at a wide range of spatial scales ranging from the local to the landscape level. Relatively new approaches in plant disease epidemiology, ranging from network to information theory, coupled with the availability of large-scale datasets and the rapid development of computer technology, are leading to revolutionary thinking about epidemics that can result in considerable improvement of strategic and tactical decision making in the control and management of plant diseases. Methods that were previously restricted to topics such as population biology or evolution are now being employed in epidemiology to enable a better understanding of the forces that drive the development of plant disease epidemics in space and time. This Focus Issue of Phytopathology features research articles that address broad themes in epidemiology including social and political consequences of disease epidemics, decision theory and support, pathogen dispersal and disease spread, disease assessment and pathogen biology and disease resistance. It is important to emphasize that these articles are just a sample of the types of research projects that are relevant to epidemiology. Below, we provide a succinct summary of the articles that are published in this Focus Issue .

Abstract
Glomus tumours are uncommon lesions of the digit. They tend to be solitary. Only a small number of multifocal cases have been published, most of which are linked to an underlying genetic disorder. Here we report an unusual case of multifocal glomus tumours in the same hand in a patient suffering from neurofibromatosis type 1.

Abstract
BACKGROUND Both sleep-duration and C-reactive protein (CRP) are useful predictors of coronary heart disease (CHD). The increased CRP level is associated with the unusual sleep-duration. However, it is unclear whether CRP impacts the CHD risk prediction of sleep-duration. METHODS AND RESULTS A total of 3381 individuals from the Framingham Offspring Study, aged 30+, CHD-free, and without missing measurement of CRP and sleep-duration and being followed to the end of 2007 were included in this analysis. Hazards ratio (HR) from the Cox regression models was used to evaluate the strength of association between the sleep-duration, CRP levels, and risk of incident CHD. Compared to sleep-duration 7-8 h (n = 2512) after adjusting for age and gender, the HR (95% CL) of incident CHD were 1.42 (1.15, 1.76, p < 0.005) for sleep-duration ≤6 h (n = 588) and 1.23 (0.90, 1.70, p < 0.2) for sleep-duration ≥9 h (n = 281), respectively. A further adjustment for other covariates including CRP did not change the CHD risk association. When subjects were categorized into 9 groups by sleep-duration (≤6, 7-8, and ≥9 h) and CRP levels (<1, 1-3, and ≥3 mg/L), and compared to those whose sleep-duration was 7-8 h and CRP levels were <1 mg/L, the HRs of CHD were similar for sleep-duration in ≤6 h or ≥9 h categories regardless of their CRP levels. The increased CRP levels, however, did show an increased risk for CHD when sleep-duration was 7-8 h CONCLUSION The levels of CRP do not significantly attenuate the association between sleep duration and incident CHD.

Abstract
Barberry (Berberis spp.) hosts the aecial stage of several rust species, including Puccinia graminis, which causes stem rust on grasses and cereals. The aecial stage of this pathogen has received less attention because it is not as economically important compared with the uredinial and telial stages. The main objective of this study was to identify and describe the rust species that were found on Berberis spp. collected in different parts of Sweden. A morphological study, including spore measurements and aecia descriptions, was conducted, as well as DNA sequence analyses (using the internal transcribed spacer region and the EF1-α gene). Based on spore and aecia morphology as well as the genetic analyses, three different taxa could be distinguished on barberry: P. graminis f. sp. avenae, P. graminis f. sp. tritci/secalis, and P. arrhenatheri. The genetic analysis revealed little or no differentiation between P. graminis f. sp. tritici and P. graminis f. sp. secalis and, thus, this group of samples was denominated P. graminis f. sp. tritici/secalis. Aecial morphology may be used to differentiate between different taxa. In particular, examination of aecial cross-sections may be used to distinguish between P. graminis f. sp. avenae and P. graminis f. sp. tritici/secalis. A clear differentiation in the mode of growth on barberry was also found; P. arrhenatheri always appeared systemic whereas P. graminis always appeared localized.

Abstract
Potato late blight, caused by Phytophthora infestans, is a major disease in potato production throughout the world. In southern Sweden, hairy nightshade (Solanum physalifolium), an alternative non-crop host to the pathogen, is an increasing weed problem. Single-lesion leaves infected by P. infestans were collected from potato and hairy nightshade to determine phenotypic and genotypic population differentiation of P. infestans between the two hosts. Genotypic variation was estimated using microsatellites as markers. The results showed no genotypic differentiation in the samples between the two hosts. Aggressiveness tests were performed using the sampled isolates to cross-inoculate potato and hairy nightshade. The proportion of infected leaves, latency period, lesion growth rate, and sporulation capacity were measured. For isolates from hairy nightshade, the odds of infection were higher on both hosts combined. When tested on potato leaves, isolates from hairy nightshade showed a significantly shorter latency period and higher sporulation capacity compared with isolates from potato. This indicates that an alternative host can filter populations of P. infestans toward a higher aggressiveness, which could lead to increasing problems in controlling potato late blight.

Abstract
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum subsp. durum) worldwide, and the most effective way to control it is through the use of resistant cultivars. A partially dominant leaf rust resistance gene present in the International Maize and Wheat Improvement Center-derived Chilean cv. Guayacan INIA and its sister line Guayacan 2 was mapped to chromosome arm 6BS by identifying linked amplified fragment length polymorphisms (AFLPs) and mapping two of the molecular markers in common wheat (T. aestivum) linkage maps of the International Triticeae Mapping Initiative and Oligoculm × Fukuho-komugi populations. Comparison of infection type responses of the two resistant durums with common wheat testers carrying the previously mapped resistance genes Lr36 and Lr53 on 6BS, and their chromosomal positions, indicated that the resistance gene in durum wheat Guayacan INIA is a new leaf rust resistance gene, which was designated as Lr61. Gene Lr61 is effective against the P. triticina race BBG/BN predominant in northwestern Mexico and other races infecting durum wheat in various countries.

Abstract
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum subsp. durum) and only a few designated resistance genes are known to occur in this crop. A dominant leaf rust resistance gene in the Chilean durum cv. Llareta INIA was mapped to chromosome arm 7BL through bulked segregant analysis using the amplified fragment length polymorphism (AFLP) technique, and by mapping three polymorphic markers in the common wheat (T. aestivum) International Triticeae Mapping Initiative population. Several simple sequence repeat (SSR) markers, including Xgwm344-7B and Xgwm146-7B, were associated with the leaf rust resistance gene. Resistance response and chromosomal position indicated that this gene is likely to be Lr14a. The SSR markers Xgwm344-7B and Xgwm146-7B and one AFLP marker also differentiated common wheat cv. Thatcher from the near-isogenic line with Lr14a, as well as durum 'Altar C84' from durum wheat with Lr14a. This is the first report of the presence of Lr14a in durum wheat, although the gene originally was transferred from emmer wheat 'Yaroslav' to common wheat. Lr14a is also present in CIMMYT-derived durum 'Somateria' and effective against Mexican and other P. triticina races of durum origin. Lr14a should be deployed in combination with other effective leaf rust resistance genes to prolong its effectiveness in durum wheat.

Abstract
ABSTRACT Decision rule models are considered to be one of the main cornerstones of the implementation of integrated pest management (IPM) programs. Even if the need for such programs to offer cost advantages over conventional strategies is a major incentive for IPM adoption, few studies focus on this financial dimension. In this article, a modeling approach of the response of a pathosystem to a disease control method and of the predictive performance of decision rules is used to explore how some basic factors act on the likelihood of adoption of decision rule models strategies (such as using an IPM system) over systematic strategies (such as systematic-spraying and never-spraying strategies). Even if the average cost of using the decision rule strategies is always lower than the average cost of systematic strategies in several different scenarios, the models developed here showed strong effects of different pathosystems and decision rules on financial benefits. The number of production situations where decision rules are of interest is highly correlated with their accuracy. However, because of the inescapable trade-offs between decision rule accuracy and limiting factors such as its user-friendly characteristics, the use of decision rules is unlikely to reduce costs to <70% of the costs of systemic strategies. In more general terms, this study provides quantitative guidelines on the financial advantage that decision rules can offer in plant protection as well as a better understanding of their potential usefulness.

Abstract
Young adults are at risk for Hepatitis B infection. Little is known about their attitudes and beliefs concerning Hepatitis B, which are determinants of getting immunized. This investigation examined risk perceptions and behavioral intentions concerning Hepatitis B among a convenience sample of 1070 young adults, 18-24 years old who participated in a Hepatitis B campaign that aired a prevention-based advertisement in movies. The campaign did not produce any significant effects. Therefore, analyses presented in this paper explored whether risk perceptions and intentions vary by sociodemographic characteristics. Most young adults do not perceive themselves to be at risk for Hepatitis B, but perceive other people to be at risk. Gender and ethnic differences in behavioral intentions to seek out Hepatitis B information were also observed. This study offers insight about important factors to consider when designing Hepatitis B prevention interventions for young adults and suggests that increasing health-promotion efforts for this group, while accounting for differences in age, culture and gender, are warranted.

Abstract
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum) in many countries. We compared the effectiveness of different types of resistance in International Maize and Wheat Improvement Center-derived durum wheat germ plasm for protecting grain yield and yield traits. In all, 10 durum wheat lines with race-specific resistance, 18 with slow-rusting resistance, and 2 susceptible were included in two yield loss trials sown on different planting dates in Mexico with and without fungicide protection under high disease pressure. Eight genotypes with race-specific resistance were immune to leaf rust. Durum wheat lines with slow-rusting resistance displayed a range of severity responses indicating phenotypic diversity. Mean yield losses for susceptible, race-specific, and slow-rusting genotypes were 51, 5, and 26%, respectively, in the normal sowing date trial and 71, 11, and 44% when sown late. Yield losses were associated mainly with a reduction in biomass, harvest index, and kernels per square meter. Slow-rusting durum wheat lines with low disease levels and low yield losses, as well as genotypes with low yield losses despite moderate disease levels, were identified. Such genotypes can be used for breeding durum wheat genotypes with higher levels of resistance and negligible yield losses by using strategies that previously have been shown to be successful in bread wheat.

Abstract
BACKGROUND The role of radiofrequency ablation (RFA) for perivascular (up to 5 mm from the major intrahepatic portal vein or hepatic vein branches) hepatocellular carcinoma (HCC) is unclear because of possible incomplete tumour ablation and potential vascular damage. This study aimed to evaluate the safety and efficacy of RFA for perivascular HCC without hepatic inflow occlusion. METHODS Between May 2001 and November 2003, RFA using an internally cooled electrode was performed on 52 patients with perivascular HCC (group 1) through open (n = 39), percutaneous (n = 9), laparoscopic (n = 2) and thoracoscopic (n = 2) approaches. Hepatic inflow occlusion was not applied during the ablation procedure. The perioperative and postoperative outcomes were compared with those of 90 patients with non-perivascular HCC (group 2) treated by RFA during the same period. RESULTS The morbidity rate was similar between groups 1 and 2 (25 versus 28 per cent; P = 0.844). One patient in group 1 (2 per cent) and two in group 2 (2 per cent) had developed thrombosis of major intrahepatic blood vessels on follow-up computed tomography scan. There were no significant differences between groups 1 and 2 in mortality rate (2 versus 0 per cent; P = 0.366), complete ablation rate for small HCC (92 versus 98 per cent; P = 0.197), local recurrence rate (11 versus 9 per cent; P = 0.762) and overall survival (1-year: 86 versus 87 per cent; 2-year: 75 versus 75 per cent; P = 0.741). CONCLUSION RFA without hepatic inflow occlusion is a safe and effective treatment for perivascular HCC.
