Programme-related stressors among part-time undergraduate nursing students

AIM: The aim of this paper is to report a study exploring the perceived stressors identified by a group of 70 students who undertook a part-time degree at one Irish university. BACKGROUND: In the literature on stress, part-time nursing students who are undertaking continuing education programmes appear to have received little attention. Stress amongst nurses is evident within the nursing literature but little information is available on the specific stressors that affect Registered Nurses who undertake further academic study. Anecdotally, students attending part-time programmes while working full-time report high levels of stress. METHOD: Quantitative methods were used. While many instruments exist to measure overall stress, this study aimed to explore student's perceptions of specific stressors associated with academic study. We used a questionnaire developed from the literature on the topic. RESULTS: Factors related to writing assignments at degree level, fulfilling personal needs and academic demands, were perceived as major stressors by these students. Factors of little concern were financial issues and attendance on the programme. Individual items receiving highest mean scores were: trying to balance work commitments and the required study (mean 3.89, sd = 1) and the prospect of the final examination (mean 3.86, sd = 1). This study was limited by the use of convenience sampling and self-report methods. Larger studies are required to support the findings. In addition, student stress was not observed or measured. CONCLUSION: Those involved in the delivery of nurse education programmes to part-time students need to consider the impact of the workload on student welfare, and to prepare students for demands of the programme.     

Lipidomic Profiling of Bronchoalveolar Lavage Fluid Extracellular Vesicles Indicates Their Involvement in Lipopolysaccharide-Induced Acute Lung Injury

Emerging data support the pivotal role of extracellular vesicles (EVs) in normal cellular physiology and disease conditions. However, despite their abundance, there is much less information about the lipid mediators carried in EVs, especially in the context of acute lung injury (ALI). Our data demonstrate that C57BL/6 mice subjected to intranasal Escherichia coli lipopolysaccharide (LPS)-induced ALI release, a higher number of EVs into the alveolar space, compared to saline-treated controls. EVs released during ALI originated from alveolar epithelial cells, macrophages, and neutrophils and carry a diverse array of lipid mediators derived from ω-3 and ω-6 polyunsaturated fatty acids (PUFA). The eicosanoids in EVs correlated with cellular levels of arachidonic acid, expression of cytosolic phospholipase A2, cyclooxygenase (COX), lipoxygenase (LOX), and cytochrome epoxygenase p450 proteins in pulmonary macrophages. Furthermore, EVs from LPS-toll-like receptor 4 knockout (TLR4^-/-) mice contained significantly lower amounts of COX and LOX catalyzed eicosanoids and ω-3 PUFA metabolites. More importantly, EVs from LPS-treated wild-type mice increased TNF-α release by macrophages and reduced alveolar epithelial monolayer barrier integrity compared to EVs from LPS-treated TLR4^−/− mice. In summary, our study demonstrates for the first time that the EV carried PUFA metabolite profile in part depends on the inflammatory status of the lung macrophages and modulates pulmonary macrophage and alveolar epithelial cell function during LPS-induced ALI.     

Distal femoral extension osteotomy and patellar tendon advancement or shortening in ambulatory children with cerebral palsy: A modified Delphi consensus study and literature review

Purpose:In children with cerebral palsy, flexion deformities of the knee can be treated with a distal femoral extension osteotomy combined with either patellar tendon advancement or patellar tendon shortening. The purpose of this study was to establish a consensus through expert orthopedic opinion, using a modified Delphi process to describe the surgical indications for distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening. A literature review was also conducted to summarize the recent literature on distal femoral extension osteotomy and patellar tendon shortening/patellar tendon advancement.Method:A group of 16 pediatric orthopedic surgeons, with more than 10 years of experience in the surgical management of children with cerebral palsy, was established. The group used a 5-level Likert-type scale to record agreement or disagreement with statements regarding distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening. Consensus for the surgical indications for distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening was achieved through a modified Delphi process. The literature review, summarized studies of clinical outcomes of distal femoral extension osteotomy/patellar tendon shortening/patellar tendon advancement, published between 2008 and 2022.Results:There was a high level of agreement with consensus for 31 out of 44 (70%) statements on distal femoral extension osteotomy. Agreement was lower for patellar tendon advancement/patellar tendon shortening with consensus reached for 8 of 21 (38%) of statements. The literature review included 25 studies which revealed variation in operative technique for distal femoral extension osteotomy, patellar tendon advancement, and patellar tendon shortening. Distal femoral extension osteotomy and patellar tendon advancement/patellar tendon shortening were generally effective in correcting knee flexion deformities and extensor lag, but there was marked variation in outcomes and complication rates.Conclusion:The results from this study will provide guidelines for surgeons who care for children with cerebral palsy and point to unresolved questions for further research.Level of evidence:level V.     

Posttraumatic distress symptoms in operable breast cancer III:

One hundred and six patients with operable breast cancer were studied at intervals one day before surgery, and at six weeks and one year post-operatively by means of taped clinical interviews and self-report questionnaires (Impact of Event Scale (IES) and General Health Questionnaire (GHQ-28)). A year after surgery, 9%reported a high level of intrusive symptoms and 10% of avoidance symptoms compared to 18% and 14% after six weeks, respectively. Based on questionnaire data, a year after surgery, thirteen patients (12%) were estimated to have a posttraumatic stress disorder (PTSD) compared to fifteen patients (14%) after six weeks. Severity of posttraumatic stress symptoms (PTSS) after one year was significantly associated with impaired psychosocial functioning over the last year previous to surgery (p < 0.05), negative life events during the year before surgery (p < 0.05), health problems during the previous ten years (p < 0.01), and a personality trait characterized by high emotional reactivity (p < 0.001). Crisis support in the acute situation, type of surgery, axillary-node metastases, and postoperative adjuvant chemotherapy did not predict subsequent PTSS. Premorbid health variables, personality, and level of distress six weeks after surgery were most important risk factors for persistent PTSS in our patients with operable breast cancer stage I and II.     

Tricuspid regurgitant jet velocity and myocardial tissue Doppler parameters predict mortality in a cohort of patients with sickle cell disease spanning from pediatric to adult age groups ‐ revisiting this controversial concept after 16 years of additional evidence

Sickle cell disease (SCD) is a monogenic hemoglobinopathy associated with significant morbidity and mortality. Cardiopulmonary, vascular and sudden death are the reasons for the majority of young adult mortality in SCD. To better understand the clinical importance of multi‐level vascular dysfunction, in 2009 we assessed cardiac function including tricuspid regurgitant jet velocity (TRV), tissue velocity in systole(S′) and diastole (E′), inflammatory, rheologic and hemolytic biomarkers as predictors of mortality in patients with SCD. With up to 9 years of follow up, we determined survival in 95 children, adolescents and adults with SCD. Thirty‐eight patients (40%) were less than 21 years old at initial evaluation. Survival and Cox proportional‐hazards analysis were performed. There was 19% mortality in our cohort, with median age at death of 35 years. In the pediatric subset, there was 11% mortality during the follow up period. The causes of death included cardiovascular and pulmonary complications in addition to other end‐organ failure. On Cox proportional‐hazards analysis, our model predicts that a 0.1 m/s increase in TRV increases risk of mortality 3%, 1 cm/s increase in S′ results in a 91% increase, and 1 cm/s decrease in E′ results in a 43% increase in mortality. While excluding cardiac parameters, higher plasma free hemoglobin was significantly associated with risk of mortality (p=.049). In conclusion, elevated TRV and altered markers of cardiac systolic and diastolic function predict mortality in a cohort of adolescents and young adult patients with SCD. These predictors should be considered when counseling cardiovascular risk and therapeutic optimization at transition to adult providers.
