Rising hospital admissions for alcohol-related cirrhosis and the impact of sex and comorbidity - a data linkage study.

OBJECTIVES: International studies have shown shifting demographic data and rising hospitalizations for alcohol-related cirrhosis (ARC), with a paucity of data from Australia. We examined hospitalizations, mortality and demographic data for people admitted with ARC over the last decade in Queensland, Australia. STUDY DESIGN: Data linkage study. METHODS: A retrospective analysis of adults hospitalized with ARC during 2008-2019 was performed using state-wide admissions data. International Classification of Diseases, 10th revision, codes identified admissions with the principal diagnosis of ARC based on validated algorithms. Comorbidity was assessed using the Charlson Comorbidity Index. RESULTS: A total of 7152 individuals had 24,342 hospital admissions with ARC (16,388 were for ARC). There was a predominance of males (72.6%) and age ≥50 years (80.4%) at index admission. Females were admitted at a significantly younger age than men (59% of women and 43% of men were aged <60 years, P < 0.001). Comorbidities were common, with 45.1% of people having at least one comorbidity. More than half (54.6%) of the patients died over the study period (median follow-up time was 5.1 years; interquartile range 2.4-8.6). Women had significantly lower mortality, with 47.6% (95% confidence interval [CI] 45.0-50.2) probability of 5-year survival, compared with 40.1% (95% CI 38.5-41.6) in men. In multivariable analysis, this was attributable to significantly lower age and comorbidity burden in women. Significantly lower survival was seen in people with higher comorbidity burden. Overall, the number of admissions for ARC increased 2.2-fold from 869 admissions in 2008 to 1932 in 2019. CONCLUSIONS: Hospital admissions for ARC have risen substantially in the last decade. Females were admitted at a younger age, with fewer comorbidities and had lower mortality compared with males. The association between greater comorbidity burden and higher mortality has important clinical implications, as comorbidity-directed interventions may reduce mortality.

A discrete choice experiment to elicit preferences for a chronic disease screening programme in Queensland, Australia.

OBJECTIVE: Patient-centred care, increasingly highlighted in healthcare strategies, necessitates understanding public preferences for healthcare service attributes. We aimed to understand the preferences of the Australian population regarding the attributes of chronic disease screening programmes. STUDY DESIGN: The preferences were elicited using the discrete choice experiment (DCE) methodology. METHODS: A DCE was administered to a sample of the Australian general population. Respondents were asked to make choices, each offering two hypothetical screening scenarios defined by screening conduct, quality and accuracy of the test results, cost to the patient, wait time and source of information. Data were analysed using a panel mixed multinomial logit model. RESULTS: A strong preference for highly accurate screening tests and nurse-led screenings at local health clinics was evident. They expressed disutility for waiting time and out-of-pocket costs but were indifferent about the source of information. Their preference for a nurse-led programme was highlighted by the fact that they were willing to pay $81 and $88 to get a nurse-led programme when they were offered a general practitioner-led and a specialist-led programme, respectively. Furthermore, they were willing to pay $32 to reduce a week of waiting time and $205 for a 95% accurate test compared to a 75% accurate test. Preferences remained consistent irrespective of the respondent's place of residence. CONCLUSIONS: Our findings highlight the importance of diagnostic test accuracy and nurse-led service delivery in chronic disease screening programmes. These insights could guide the development of patient-centric services by enhancing test accuracy, reducing waiting times and promoting nurse-led care models.

High-fidelity simulation: A practice model for nurse educators at a South African private higher education institution

Background. The clinical skills development of student nurses is one of many challenges facing nursing education owing to a lack of available clinical placements and learning opportunities. Simulation training as an optional teaching-learning method creates an environment where clinical skills are developed and students are prepared for the nursing profession. The successful implementation of high-fidelity simulation (HFS) strategies as part of the nursing curricula requires nurse educators to have knowledge and skills. At the South African private higher education institution (SAPHEI) where the research for this study was done, it became evident that nurse educators do not have the required knowledge, skills or support to implement HFS. The absence of evidence in the literature of a practice model for a SAPHEI to facilitate the implementation of HFS reveals a gap in the practice base of nursing education.Objective. To develop a practice model for nurse educators at a SAPHEI to facilitate the implementation of HFS.Methods. The researcher used a theory-generative research design. The study was conducted in two phases, with two steps in each phase, to address four objectives in all.Results. Phase 1 identified and described the main and related concepts. A resulting conceptual framework was used for the development of the practice model. Phase 2 addressed the relational meaning of the main and related concepts, as well as the construction of the practice model through theory synthesis.Conclusion. The main aim of this research study was to develop a practice model for nurse educators at a SAPHEI to facilitate the implementation of HFS as part of the clinical skills development of student nurses. The practice model offers a schematic outline that represents HFS as a teaching-learning method. The importance of the outline lies therein that it specifies the context and situations in which the model is useful

Introduction of standardized, cumulative quantitative measurement of blood loss into routine maternity care.

INTRODUCTION: Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity in the UK. Visual estimation of blood loss is unreliable yet remains common practice. As part of a national quality improvement project to improve care during PPH, standardized, quantitative measurement of blood loss (QBL) for all deliveries was introduced into a tertiary obstetric unit in Cardiff, Wales. METHODS: Retrospective analysis of 875 consecutive maternities between December 2017 and February 2018 was undertaken. Of these, 372 mothers had both pre- and post-partum hemoglobin (Hb) were recorded. Regression analyses were performed to investigate the relationship between change in Hb adjusted for red cell transfusion and QBL. RESULTS: The correlation coefficient between QBL and adjusted change in Hb for all deliveries (n = 372) was 0.57. This corresponded to an estimated fall of adjusted change in Hb of 15.3 g/L (95% CI: 13.1, 17.6) per 1000 mL blood loss. DISCUSSION: QBL has been shown to be reliable across all maternity settings, with reproducible results in theater and delivery rooms (on the obstetric unit and alongside midwifery-led unit). QBL is moderately correlated with adjusted change in Hb for all volumes of bleeding and gives clinicians more accurate knowledge of blood loss than visual estimation. This low-cost, low-fidelity intervention can influence the timely escalation of clinical care and therefore patient outcome.

The mobilisation of early mature CD56dim-CD16bright NK cells is blunted following a single bout of vigorous intensity exercise in Type 1 Diabetes.

Type 1 diabetes (T1D) is a T cell mediated autoimmune disease that targets and destroys insulin-secreting pancreatic beta cells. Although T cell mediated, a number of other immune cells are also critically involved in coordinating the events leading to T1D. Specifically, innate subsets play an important role in the pathogenesis of T1D. NK cells are one of the first cell types to infiltrate the pancreas, causing damage and release of beta cell antigens. Previous work in our group has shown differential mobilisation of highly differentiated CD8+ T cells during vigorous intensity exercise in T1D compared to a control cohort. Here, we aimed to explore exercise-induced mobilisation of other cell types involved in T1D pathogenesis. In this study, we investigated the effects of a single bout of vigorous (80% predicted VO2max) intensity exercise on innate cell mobilisation in T1D and control participants. T1D (N=12, mean age 33.2yrs, predicted VO2max 32.2 ml.kg.min⁻¹, BMI 25.3 kg.m⁻²) and control (N=12, mean age 29.4yrs, predicted VO2 max 38.5 ml.kg.min⁻¹, BMI 23.7 kg.m⁻² male participants completed a 30-minute bout of cycling at 80% predicted VO2 max in a fasted state. Peripheral blood was collected at baseline, immediately post-exercise, and 1 hour post-exercise. NK cell subsets mobilised during vigorous intensity exercise in both control and T1D participants. However, mature NK cells, defined as the CD56dimCD16bright subset, displayed a lower percentage increase following vigorous intensity exercise in T1D participants (Control: 185.12%, T1D: 97.06%). This blunted mobilisation was specific to early mature NK cells (KIR+) but not later differentiated NK cells (KIR+CD57+). Myeloid lineage subsets mobilised to a similar extent in both control and T1D participants. In conclusion, vigorous exercise mobilises innate immune cells in people with T1D albeit to a different extent to those without T1D. This mobilisation of innate immune cells provides a mechanistic argument to support exercise in people with T1D where it has the potential to improve surveillance for infection and to modulate the autoimmune response to the beta cell.

Factors influencing surgical treatment decisions for breast cancer: a qualitative exploration of surgeon and patient perspectives.

Background: The rate of mastectomy is much higher in Newfoundland and Labrador than in any other province in Canada, even for women diagnosed at an early stage. In this paper, we present qualitative data from women who have made a decision for surgical treatment and from breast surgeons in an effort to better explicate factors influencing breast cancer (bca) surgical decision-making. Methods: The study's descriptive, qualitative design involved holding interviews with breast surgeons and holding focus groups and interviews with women who were offered the choice of breast-conserving surgery (bcs) or mastectomy (mt). Results: Participants included 35 women and 13 surgeons. High interest in mt and increasing requests for prophylactic contralateral mt were evident. A host of factors-clinical, demographic, psychosocial, education-related, and cultural-influenced the decisions. A key factor for women was fear of recurrence and a need to "just get rid of it," but the experiences of others also influenced the decisions. Life stage and family considerations also factored prominently into women's decisions. Conclusions: Women with early-stage bca more often chose mt and often demanded prophylactic removal of the healthy breast. Findings highlight the importance of ensuring that women at average risk are appropriately counselled about the low likelihood of a subsequent contralateral bca and the lack of survival benefit associated with prophylactic contralateral mt. Findings also revealed other areas of presurgical discussion that might help women think through their personal circumstances and values so as to encourage informed surgical decisions.

Symposium review: Omics in dairy and animal science-Promise, potential, and pitfalls.

Sequencing the first genome took 15 yr and $3 billion to complete. Currently, a genome can be sequenced in a day for a few thousand dollars. Comparing the relative abundance of nearly every mRNA transcript and small RNAs from cells and tissues from different experimental conditions has become so easy that it can take longer to transfer the data between computers than to perform the experiment. Nucleotide sequencing techniques have become so sensitive that the greatest concern is not detecting a gene or transcript but rather, falsely identifying one. Better genome sequencing has led to more complete transcriptomic and proteomic databases and, combined with more sensitive instrumentation and separation techniques, is bringing us closer to detecting complete transcriptomes and proteomes. The promise of these powerful omics techniques is to lead us to new and unexpected connections between molecular processes in the context of animal health. This promise cannot be achieved without hypothesis-driven research that connects omics data with animal health experiments. Any researcher who wishes to invest the time and resources in omics experiments should be aware of the common pitfalls and limitations of these techniques so they can avoid these issues and maximize the use of these research tools. Several important questions must be asked: What is the quality of the databases and how they are annotated? Are the annotations based on experimental results or computational predictions? What assumptions are made by the analysis algorithms, and how will this affect the result? Finally, how can the research community use the vast amount of data being generated by omics experiments in ways to achieve the goals of better animal health and production (which is the promise of omics technologies)? Until the observations shown in omics data sets are used to achieve the goals of better animal health and production, the potential of omics technology will not be fully realized.
