RESUMO

Introduction: The Calgary-Cambridge Model (C-CM), developed by Kurtz and Silverman in 1996, is a communication tool developed for doctors. Since its publication, it has been adopted by various healthcare professionals; however, no previous research has been identified that evaluates its use in paramedic practice. This study aims to explore the experience of students and newly qualified paramedics (NQPs) applying the C-CM in practice, and establish their experiences and perceptions of its suitability as a communication tool in the pre-hospital environment. Methods: This MSc research project, conducted in April-May 2021, applied qualitative methods with thematic analysis to written reflections and semi-structured interview transcripts discussing the implementation of C-CM in paramedic practice. A convenience-quota sample of 11 participants, consisting of third-year paramedic students and recent NQPs, were recruited. This research is reported using Consolidated Criteria for Reporting Qualitative Research (COREQ) reporting guidelines. Results: Eleven participants were recruited in total; nine consented to reflective writing analysis and interviews, two consented to writing analysis only. Analysis of the writing samples allowed for a deductive approach to the interview plan. Participants consisted of seven males and four females. All eleven participants (ten British and one Indian) spoke English as a first language. Ages ranged from 18 to 59 years. Career status was 46.2% third-year students and 53.8% NQPs. Four major themes were identified: barriers to implementation of the C-CM in practice; impact of C-CM on paramedic practice; C-CM as a teaching and learning tool in paramedic practice; and adaptation of C-CM for paramedic practice. Conclusions: Participants suggested that implementation of C-CM leads to improved structure and shared decision-making; however, adaptions to make it more paramedic-focused would be welcomed. The diversity of patients and their preferences can make its implementation challenging, and the negative feedback received from experienced ambulance staff was a significant concern to participants.

RESUMO

AIM: Approximately 4000 patients in the UK have an emergency intestinal stoma formed each year. Stoma-related complications (SRCs) are heterogeneous but have previously been subcategorized into early or late SRCs, with early SRCs generally occurring within 30 days postoperatively. Early SRCs include skin excoriation, stoma necrosis and high output, while late SRCs include parastomal hernia, retraction and prolapse. There is a paucity of research on specific risk factors within the emergency cohort for development of SRCs. This paper aims to describe the incidence of SRCs after emergency intestinal surgery and to identify potential risk factors for SRCs within this cohort. METHOD: Consecutive patients undergoing emergency formation of an intestinal stoma (colostomy, ileostomy or jejunostomy) were identified prospectively from across three acute hospital sites over a 3-year period from the ELLSA (Emergency Laparotomy and Laparoscopic Scottish Audit) database. All patients were followed up for a minimum of 1 year. A multivariate logistic regression model was used to identify risk factors for early and late SRCs. RESULTS: A total of 455 patients were included (median follow-up 19 months, median age 64 years, male:female 0.52, 56.7% ileostomies). Early SRCs were experienced by 54.1% of patients, while 51% experienced late SRCs. A total of 219 patients (48.1%) had their stoma sited preoperatively. Risk factors for early SRCs included end ileostomy formation [OR 3.51 (2.24-5.49), p < 0.001], while preoperative stoma siting was found to be protective [OR 0.53 (0.35-0.83), p = 0.005]. Patient obesity [OR 3.11 (1.92-5.03), p < 0.001] and reoperation for complications following elective surgery [OR 4.18 (2.01-8.69), p < 0.001] were risk factors for late SRCs. CONCLUSION: Stoma-related complications after emergency surgery are common. Preoperative stoma siting is the only truly modifiable risk factor to reduce SRCs, and further research should be aimed at methods of improving the frequency and accuracy of this in the emergency setting.

RESUMO

The dominant cause of malaria in Malaysia is now Plasmodium knowlesi, a zoonotic parasite of cynomolgus macaque monkeys found throughout South East Asia. Comparative genomic analysis of parasites adapted to in vitro growth in either cynomolgus or human RBCs identified a genomic deletion that includes the gene encoding normocyte-binding protein Xa (NBPXa) in parasites growing in cynomolgus RBCs but not in human RBCs. Experimental deletion of the NBPXa gene in parasites adapted to growth in human RBCs (which retain the ability to grow in cynomolgus RBCs) restricted them to cynomolgus RBCs, demonstrating that this gene is selectively required for parasite multiplication and growth in human RBCs. NBPXa-null parasites could bind to human RBCs, but invasion of these cells was severely impaired. Therefore, NBPXa is identified as a key mediator of P. knowlesi human infection and may be a target for vaccine development against this emerging pathogen.

RESUMO

In the crystal of the title mol-ecular salt (systematic name: 2-acetyl-pyridinium 2,5-dibromo-4-hydr-oxy-3,6-dioxocyclo-hexa-1,4-dienolate), C(7)H(8)NO(+)·C(6)HBr(2)O(4) (-), centrosymmetric rings consisting of two cations and two anions are formed, with the components linked by alternating O-H⋯O and N-H⋯O hydrogen bonds. Short O⋯Br contacts [3.243 (2) and 3.359 (2) Å] may help to consolidate the packing.
