The research evaluates a collaborative case study to co-create the curriculum for a tourism undergraduate module. In three course design team (CDT) meetings, students selected and discussed topics and learning styles. Qualitative analysis revealed that the students involved strove to be independent learners. They favoured active learning styles and ‘non-vocational’ aspects of tourism. However, university bureaucracy represents a block in the design process. The paper concludes by advocating a more equal relationship between students and tutors. This involves a shift in power relations, inverting traditional hierarchies in which teachers act as gatekeepers of knowledge and students are passive recipients. [ABSTRACT FROM AUTHOR]

Abstract: Tourism is viewed as an increasingly important component of rural economic potential, especially in peripheral regions of the UK. As a sector, however, it is dominated by low skilled employment, seasonal demand cycles and perceived low levels of innovation and entrepreneurship. In this paper we explore the role of in-migrant owners of small tourism firms (STFs) in promoting entrepreneurship and developing competition in the tourism economy of Northumberland. We hypothesise that through a combination of extra-local networks and local embeddedness these business owners are not only succeeding for themselves but they are stimulating other local businesses by increasing local trade, heightening competition and raising standards and aspirations among all STFs.

Objectives: This study assessed the effect of pharmacogenetics on the antiplatelet effect of clopidogrel. Background: Variability in clopidogrel response might be influenced by polymorphisms in genes coding for drug metabolism enzymes (cytochrome P450 [CYP] family), transport proteins (P-glycoprotein) and/or target proteins for the drug (adenosine diphosphate–receptor P2Y12). Methods: Sixty patients undergoing elective percutaneous coronary intervention in the randomized PRINC (Plavix Response in Coronary Intervention) trial had platelet function measured using the VerifyNow P2Y12 analyzer after a 600-mg or split 1,200-mg loading dose and after a 75- or 150-mg daily maintenance dosage. Polymerase chain reaction–based genotyping evaluated polymorphisms in the CYP2C19, CYP2C9, CYP3A4, CYP3A5, ABCB1, P2Y12, and CES genes. Results: CYP2C19*1*1 carriers had greater platelet inhibition 2 h after a 600-mg dose (median: 23%, range: 0% to 66%), compared with platelet inhibition in CYP2C19*2 or *4 carriers (10%, 0% to 56%, p = 0.029) and CYP2C19*17 carriers (9%, 0% to 98%, p = 0.026). CYP2C19*2 or *4 carriers had greater platelet inhibition with the higher loading dose than with the lower dose at 4 h (37%, 8% to 87% vs. 14%, 0% to 22%, p = 0.002) and responded better with the higher maintenance dose regimen (51%, 15% to 86% vs. 14%, 0% to 67%, p = 0.042). Conclusions: Carriers of the CYP2C19*2 and *4 alleles showed reduced platelet inhibition after a clopidogrel 600-mg loading dose but responded to higher loading and maintenance dose regimens. Genotyping for the relevant gene polymorphisms may help to individualize and optimize clopidogrel treatment.

Objectives: This study evaluated the antiplatelet effect of a higher loading and maintenance dose regimen of clopidogrel and a possible drug interaction with verapamil. Background: Clopidogrel loading doses above 600 mg have not resulted in more rapid or complete platelet inhibition. Higher maintenance dosages may be more effective than 75 mg/day. Methods: A double-blind, randomized, placebo-controlled trial was undertaken in 60 patients undergoing percutaneous coronary intervention. All patients received clopidogrel 600 mg at the start of the procedure. Using a 2 × 2 design, patients were allocated to clopidogrel 600 mg given 2 h later or matching placebo, and to verapamil 5 mg intra-arterial or placebo. Platelet function was measured using the VerifyNow P2Y12 analyzer (Accumetrics Ltd., San Diego, California) at 2, 4, and 7 h. Patients were further randomized to receive a clopidogrel 75 or 150 mg once daily, with platelet function assessed after 1 week. Results: Two hours after the second dose of clopidogrel or placebo, platelet inhibition was 42 ± 27% with clopidogrel, compared with 24 ± 22% with placebo (p = 0.0006). By 5 h after the second dose, platelet inhibition was 49 ± 30% with clopidogrel, compared with 29 ± 22% with placebo (p = 0.01). No drug interaction was seen with verapamil. A clopidogrel maintenance dosage of 150 mg daily for 1 week resulted in greater platelet inhibition than 75 mg daily (50 ± 28% vs. 29 ± 19%, p = 0.01). Conclusions: In an unselected population undergoing percutaneous coronary intervention a clopidogrel 1,200-mg loading dose, given as two 600-mg doses 2 h apart, results in more rapid and complete platelet inhibition than a single 600-mg dose. A maintenance dosage of 150 mg daily produces greater platelet inhibition than 75 mg daily. (The PRINC trial; ACTRN12606000129583) [Copyright &y& Elsevier]

Patients with cardiovascular disease taking aspirin and some nonsteroidal anti-inflammatory drugs (NSAIDs) appear to have increased vascular events. This study was conducted to compare the ex vivo antiplatelet effects of 6 commonly used NSAIDs and to determine whether these agents antagonize the effect of aspirin. Platelet function was assessed by Platelet Function Analyzer 100 closure time in normal subjects in a randomized, blinded, multiple-crossover study. Platelet function was measured 12 hours after the administration of each NSAID. The NSAID was then given 2 hours before aspirin 300 mg, and platelet function was reassessed 24 hours later. At 12 hours after the administration of naproxen and tiaprofenic acid, closure time was significantly prolonged, whereas the other NSAIDs did not cause significant prolongations. Compared with placebo plus aspirin, closure time was significantly reduced when ibuprofen, indomethacin, naproxen, or tiaprofenic acid was given before aspirin. In conclusion, ibuprofen, indomethacin, naproxen, and tiaprofenic acid all block the antiplatelet effect of aspirin. Sulindac and celecoxib did not demonstrate any significant antiplatelet effect or reduce the antiplatelet of aspirin and, therefore, of the NSAIDs evaluated may be the drugs of choice for patients requiring aspirin and NSAIDs.

Abstract: Hyperthyroidism has profound effects on mental health. The literature is sparse, however, with regard to suicide attempts related to untreated hyperthyroidism. This case report illustrates the presentation of a patient in the intensive care unit after a life-threatening Tylenol overdose presumed to be secondary to adjustment disorder. During the patient's hospitalization, she experienced anxiety, heart palpitations, tachycardia and diaphoresis. The psychiatric consultant, endocrinology consultant and inpatient psychiatry teams helped to diagnose Graves’ disease, significantly changing her treatment and trajectory. [Copyright &y& Elsevier]
