    Implementing Care Aims in an integrated team

    Get PDF
    Care Aims is increasingly being used as a model of care within NHS services, particularly by allied health professionals. This article reports the findings of a pilot study exploring the impact of implementing Care Aims in an integrated community health team. It describes the main findings, and discusses the factors that appeared to impact on the implementation and use of the Care Aims approach in these teams. The model has been traditionally used in uni-professional teams rather than integrated teams. This case study suggests Care Aims has potential to support integrated team working. In this study, clinicians perceived Care Aims was a model that could improve care for patients, support professionals working together and support self-management. However, it is unclear whether it was Care Aims itself or the training and discussion that took place that enabled this team to develop and agree more consistent working practices. Similar to previous studies, this study has shown how team and professional culture can influence how team members work together and provide care in an integrated way. Team and professional cultures are also shown to influence how team members approach and embrace that change. As such, Care Aims may be more challenging to some staff groups to implement

    Background: Use of statins has been associated with a reduced incidence of esophageal adenocarcinoma in population-based studies. However there are few studies examining statin use and the development of Barrett’s esophagus. Aim: The purpose of this study was to examine the association between statin use and the presence of Barrett’s esophagus in patients having their first gastroscopy. Methods: We have performed a case–control study comparing statin use between patients with, and without, an incident diagnosis of non-dysplastic Barrett’s esophagus. Male Barrett’s cases (134) were compared to 268 male age-matched controls in each of two control groups (erosive gastro-esophageal reflux and dyspepsia without significant upper gastrointestinal disease). Risk factor and drug exposure were established using standardised interviews. Logistic regression was used to compare statin exposure and correct for confounding factors. We performed a meta-analysis pooling our results with three other case–control studies. Results: Regular statin use was associated with a significantly lower incidence of Barrett’s esophagus compared to the combined control groups [adjusted OR 0.62 (95 % confidence intervals 0.37–0.93)]. This effect was more marked in combined statin plus aspirin users [adjusted OR 0.43 (95 % CI 0.21–0.89)]. The inverse association between statin or statin plus aspirin use and risk of Barrett’s was significantly greater with longer duration of use. Meta-analysis of pooled data (1098 Barrett’s, 2085 controls) showed that statin use was significantly associated with a reduced risk of Barrett’s esophagus [pooled adjusted OR 0.63 (95 % CI 0.51–0.77)]. Conclusions: Statin use is associated with a reduced incidence of a new diagnosis of Barrett’s esophagus

    Urogenital symptoms: prevalence, bother, associations and impact in 22 year-old women of the Raine Study

    Introduction and hypothesis: Urogenital symptoms are prevalent in older women, but there is little data available on the prevalence, bother, impact and associations with low back pain (LBP), obesity, parity, mental health (MH) and quality of life (QOL) in young women. Our aim was to determine the prevalence, bother and impact of urogenital symptoms and to explore associations with LBP, obesity, parity, MH and QOL in 22 year-old women. Methods: This was a cross-sectional evaluation using data collected from 588 women in the Raine Study, a pregnancy cohort in which participants have been regularly followed up from birth until 22 years. Data was analysed using descriptive statistics, univariate comparisons and linear regression models. Results: Prevalence of urogenital symptoms were stress urinary incontinence (SUI) 6.3%, mixed urinary incontinence (MUI) 11.5%, leakage of drops 5.8%, urge urinary incontinence (UUI) 5.3%, bothersome urinary frequency 41.5%, difficulty emptying 11.8% and urogenital pain 22.9%. Urinary frequency, MUI, difficulty emptying and urogenital pain were most bothersome, whilst difficulty emptying and urogenital pain were associated with greatest impact. Urinary frequency, SUI, leakage of drops, difficulty emptying and urogenital pain were associated with current LBP and LBP ever. Difficulty emptying and urogenital pain were associated with chronic LBP. Urogenital symptoms were not associated with obesity or parity. Women with urogenital symptoms had significantly poorer scores on the Mental Component Score of the Short Form Health Survey (SF)-12 and all aspects of the Depression Anxiety Stress Score. Conclusions: Urogenital symptoms are prevalent in young women, bothersome for some and are associated with LBP, poorer MH and reduced QOL

    The Total Syntheses of JBIR-94 and Two Synthetic Analogs and Their Cytotoxicities Against A549 (CCL-185) Human Small Lung Cancer Cells

    Get PDF
    We here disclose the total syntheses of the natural polyphenol JBIR-94 and two nonnatural analogs, whose structures are of interest for their bioactivity potential as radical scavengers. Although we initially attempted this by dually acylating both of putrecine’s amine nitrogens in a single pot, our endeavors with this method (which has been successfully reported by other groups) proved ineffectual. We accordingly opted for the lengthier approach of acylating each amine individually, which gratuitously prevailed and also aligns with separate literature precedent. Moreover, we here share our analysis of these target compounds’ cytotoxicities and IC50 values against A549 (CCL-185) human small lung cancer cells

    The effect of social media communication on consumer perceptions of brands

    Get PDF
    Researchers and brand managers have limited understanding of the effects social media communication has on how consumers perceive brands. We investigated 504 Facebook users in order to observe the impact of firm-created and user-generated social media communication on brand equity, brand attitude and purchase intention by using a standardized online survey throughout Poland. To test the conceptual model, we analyzed 60 brands across three different industries: non-alcoholic beverages, clothing and mobile network operators. When analyzing the data, we applied the structural equation modeling technique to both investigate the interplay of firm-created and user-generated social media communication and examine industry-specific differences. The results of the empirical studies showed that user-generated social media communication had a positive influence on both brand equity and brand attitude, whereas firm-created social media communication affected only brand attitude. Both brand equity and brand attitude were shown to have a positive influence on purchase intention. In addition, we assessed measurement invariance using a multi-group structural modeling equation. The findings revealed that the proposed measurement model was invariant across the researched industries. However, structural path differences were detected across the models

    Bardet-Biedl Syndrome ciliopathy is linked to altered hematopoiesis and dysregulated self-tolerance

    Get PDF
    Bardet–Biedl Syndrome (BBS) is a pleiotropic genetic disease caused by the dysfunction of primary cilia. The immune system of patients with ciliopathies has not been investigated. However, there are multiple indications that the impairment of the processes typically associated with cilia may have influence on the hematopoietic compartment and immunity. In this study, we analyze clinical data of BBS patients and corresponding mouse models carrying mutations in Bbs4 or Bbs18. We find that BBS patients have a higher prevalence of certain autoimmune diseases. Both BBS patients and animal models have altered red blood cell and platelet compartments, as well as elevated white blood cell levels. Some of the hematopoietic system alterations are associated with BBS‐induced obesity. Moreover, we observe that the development and homeostasis of B cells in mice is regulated by the transport complex BBSome, whose dysfunction is a common cause of BBS. The BBSome limits canonical WNT signaling and increases CXCL12 levels in bone marrow stromal cells. Taken together, our study reveals a connection between a ciliopathy and dysregulated immune and hematopoietic systems

    Bardet-Biedl syndrome is a rare autosomal recessive, multisystem disease characterized by retinal dystrophy, renal malformation, obesity, intellectual disability, polydactyly, and hypogonadism. Nineteen disease-causing genes (BBS1-19) have been identified, of which mutations in BBS1 are most common in North America and Europe. A hallmark of the disease, renal malformation is heterogeneous and is a cause of morbidity and mortality through the development of CKD. We studied the prevalence and severity of CKD in 350 patients with Bardet-Biedl syndrome-related renal disease attending the United Kingdom national Bardet-Biedl syndrome clinics to further elucidate the phenotype and identify risk indicators of CKD. Overall, 31% of children and 42% of adults had CKD; 6% of children and 8% of adults had stage 4-5 CKD. In children, renal disease was often detected within the first year of life. Analysis of the most commonly mutated disease-associated genes revealed that, compared with two truncating mutations, two missense mutations associated with less severe CKD in adults. Moreover, compared with mutations in BBS10, mutations in BBS1 associated with less severe CKD or lack of CKD in adults. Finally, 51% of patients with available ultrasounds had structural renal abnormalities, and 35% of adults were hypertensive. The presence of structural abnormalities or antihypertensive medication also correlated statistically with stage 3b-5 CKD. This study describes the largest reported cohort of patients with renal disease in Bardet-Biedl syndrome and identifies risk factors to be considered in genetic counseling

    Implementation of a novel stratified PAthway of CarE for common musculoskeletal (MSK) conditions in primary care: Protocol for a multicentre pragmatic randomised controlled trial (the PACE MSK trial)

    Get PDF
    Introduction Musculoskeletal (MSK) conditions constitute the highest burden of disease globally, with healthcare services often utilised inappropriately and overburdened. The aim of this trial is to evaluate the effectiveness of a novel clinical PAthway of CarE programme (PACE programme), where care is provided based on people's risk of poor outcome. Methods and analysis Multicentre randomised controlled trial. 716 people with MSK conditions (low back pain, neck pain or knee osteoarthritis) will be recruited in primary care. They will be stratified for risk of a poor outcome (low risk/high risk) using the Short Form Örebro Musculoskeletal Pain Screening Questionnaire (SF-ÖMSPQ) then randomised to usual care (n=358) or the PACE programme (n=358). Participants at low risk in the PACE programme will receive up to 3 sessions of guideline based care from their primary healthcare professional (HCP) supported by a custom designed website (mypainhub.com). Those at high risk will be referred to an allied health MSK specialist who will conduct a comprehensive patient-centred assessment then liaise with the primary HCP to determine further care. Primary outcome (SF 12-item PCS) and secondary outcomes (eg, pain self-efficacy, psychological health) will be collected at baseline, 3, 6 and 12 months. Cost-effectiveness will be measured as cost per quality-Adjusted life-year gained. Health economic analysis will include direct and indirect costs. Analyses will be conducted on an intention-To-Treat basis. Primary and secondary outcomes will be analysed independently, using generalised linear models. Qualitative and mixed-methods studies embedded within the trial will evaluate patient experience, health professional practice and interprofessional collaboration. Ethics and dissemination Ethics approval has been received from the following Human Research Ethics Committees: The University of Sydney (2018/926), The University of Queensland (2019000700/2018/926), University of Melbourne (1954239), Curtin University (HRE2019-0263) and Northern Sydney Local Health District (2019/ETH03632). Dissemination of findings will occur via peer-reviewed publications, conference presentations and social media. Trial registration number ACTRN12619000871145
