Commentary on "Older carers of people with learning disabilities: Their experiences with local authority assessment processes and personnel"
Get PDFPurpose - The purpose of this paper is to provide a commentary on "Older carers of people with learning disabilities: their experiences with local authority assessment processes and personnel" written by Rachel Forrester-Jones. Design/methodology/approach - The commentary considers the experiences of older carers in the context of research, legislative and policy changes over the last 30+ years.
Findings - The needs of older carers of adults with learning disabilities are well recognised within the (limited) literature. Less attention has been given to practical strategies to identify and support such carers or to their broader family context.
Originality/value - This commentary highlights that assessors carrying out carers' needs assessments should consider whether adults with learning disabilities are providing care to their older relative. The recognition of possible mutual or reciprocal
care needs to be acknowledged and appropriate support offered
The psychological distress in healthcare workers: Current perspectives and challenges
No full textAims and objectives. The review presents evidenced-based literature on psychological distress amongst health care professionals; the work is not a systematic review but covers a wide selection of contemporary literature and covers the COVID-19 pandemic. The review discusses several reasons why psychological distress within health care professionals requires separate consideration and strategies to support resilience and access to support.
Background. Health care workers report high workplace stress levels, burnout, psychological distress, and an increased risk of mental health problems. This is when the World Health Organisation recommends supporting health care professionals’ mental health and social aspects. It is also accepted that the physical and mental ill-health in health care workers can impact operational effectiveness and delivery of patient outcomes.
Literature review. The integrative review utilized keywords to undertake a search of the literature. The following key terms ‘healthcare worker,’ ‘health professional,’ ‘mental health,’ ‘resilience,’ ‘support,’ ‘social risk factors,’ ‘physical risk factors’ and ‘Intervention.’ The PsycINFO, CINAHL and Embase and the Cochrane library were searched to find contemporary research articles.
Conclusions. The review has collated the available evidence and recommendations for supporting healthcare workers. It is recognized that stressors can increase the prevalence of psychological distress and lead to recruitment and retention issues. Stressors for psychological distress in health care professionals are the impact of patient-specific situations, interprofessional working relationships and perceived workload burden

First, the approximation relationship between the adjustment value and panel elastic deformation is established. Subsequently, a panel adjustment matrix for the whole reflector is derived to calculate the reflector deformation caused by the actuator adjustment. Next, the root mean square (rms) error of the deformed reflector is expressed as a quadratic form in the matrix form, and the adjustment value can be derived easily and promptly from the corresponding extreme value. The solution is expected to be unique and optimal since the aforementioned quadratic form is a convex function. Finally, a 35 m reflector antenna is adopted to perform the panel adjustments, and the effect of the adjustment errors is discussed. The results show that compared to the traditional model, where the panel elastic deformation is not considered, the proposed method exhibits a higher accuracy and is more suitable for use in large reflectors with a high operation frequency. The adjustment errors in different rings exert different influences on the gain and sidelobe level, which can help determine the actuator distribution with different precisions
Associate Teachers’ views on dialogic mentoring
Get PDFThis document is the Accepted Manuscript version of a published work that appeared in final form in Teachers and Teaching: Theory and practice. To access the final edited and published work see http://dx.doi.org/10.1080/13540602.2021.1933421The aim of this paper is to examine Associate Teachers’ (ATs) views on dialogic mentoring. More specifically it consider, the views of 48 ATs who were involved in an Initial Teacher Education (ITE) partnership that has emerged in response to several changes that have occurred in Welsh education. Educational reforms in Wales have highlighted the value of mentoring and the new ITE partnership is uniquely committed to a dialogic approach. A questionnaire and three focus group interviews were used to generate data from the 48 ATs who were completing a one-year postgraduate programme. Thematic analysis was then used to interrogate the data and identify patterns of response. Adopting a dialogic approach was found to remove some of the anxiety around formal observations and help establish trusting collaborative relationships where ATs were willing to take risks. The dialogic approach was more democratic and gave ATs a stronger voice, but this also created some conflict as mentors’ own beliefs were more likely to be questioned. The dialogic approach relied on mentors being fully invested in the process
and being committed to open conversations about learning
Ultraviolet light-induced collagen degradation inhibits melanoma invasion.
Get PDFFrom Europe PMC via Jisc Publications RouterHistory: ppub 2021-05-01, epub 2021-05-12Publication status: PublishedFunder: Wellcome Trust; Grant(s): 110078/Z/15/ZFunder: Cancer Research UK; Grant(s): A27412Ultraviolet radiation (UVR) damages the dermis and fibroblasts; and increases melanoma incidence. Fibroblasts and their matrix contribute to cancer, so we studied how UVR modifies dermal fibroblast function, the extracellular matrix (ECM) and melanoma invasion. We confirmed UVR-damaged fibroblasts persistently upregulate collagen-cleaving matrix metalloprotein-1 (MMP1) expression, reducing local collagen (COL1A1), and COL1A1 degradation by MMP1 decreased melanoma invasion. Conversely, inhibiting ECM degradation and MMP1 expression restored melanoma invasion. Primary cutaneous melanomas of aged humans show more cancer cells invade as single cells at the invasive front of melanomas expressing and depositing more collagen, and collagen and single melanoma cell invasion are robust predictors of poor melanoma-specific survival. Thus, primary melanomas arising over collagen-degraded skin are less invasive, and reduced invasion improves survival. However, melanoma-associated fibroblasts can restore invasion by increasing collagen synthesis. Finally, high COL1A1 gene expression is a biomarker of poor outcome across a range of primary cancers

The Recognition of Excessive blood loss At ChildbirTh (REACT) Study: a two‐phase exploratory, sequential mixed methods inquiry using focus groups, interviews and a pilot, randomised crossover study
Get PDFFrom Wiley via Jisc Publications RouterHistory: accepted 2021-04-16, pub-electronic 2021-05-27Article version: VoRPublication status: PublishedFunder: Research Trainees Coordinating Centre; Id: http://dx.doi.org/10.13039/501100000659; Grant(s): DRF‐2012‐05‐140Objectives: To explore how childbirth‐related blood loss is evaluated and excessive bleeding recognised; and to develop and test a theory of postpartum haemorrhage (PPH) diagnosis. Design: Two‐phase, exploratory, sequential mixed methods design using focus groups, interviews and a pilot, randomised crossover study. Setting: Two hospitals in North West England. Sample: Women (following vaginal birth with and without PPH), birth partners, midwives and obstetricians. Methods: Phase 1 (qualitative): 8 focus groups and 20 one‐to‐one, semi‐structured interviews were conducted with 15 women, 5 birth partners, 11 obstetricians, 1 obstetric anaesthetist and 19 midwives (n = 51). Phase 2 (quantitative): 11 obstetricians and ten midwives (n = 21) completed two simulations of fast and slow blood loss using a high‐fidelity childbirth simulator. Results: Responses to blood loss were described as automatic, intuitive reactions to the speed, nature and visibility of blood flow. Health professionals reported that quantifying volume was most useful after a PPH diagnosis, to validate intuitive decisions and guide ongoing management. During simulations, PPH treatment was initiated at volumes at or below 200 ml (fast mean blood loss 79.6 ml, SD 41.1; slow mean blood loss 62.6 ml, SD 27.7). All participants treated fast, visible blood loss, but only half treated slow blood loss, despite there being no difference in volumes (difference 18.2 ml, 95% CI −5.6 to 42.2 ml, P = 0.124). Conclusions: Experience and intuition, rather than blood loss volume, inform recognition of excessive blood loss after birth. Women and birth partners want more information and open communication about blood loss. Further research exploring clinical decision‐making and how to support it is required. Tweetable abstract: During a PPH, clinical decision‐making is intuitive with clinicians treating as soon as excessive loss is recognised
Physiological characteristics of female soccer players and health and performance considerations: A narrative review
Get PDFThe final publication is available at Springer via http://dx.doi.org/10.1007/s40279-021-01458-1Female soccer has seen a substantial rise in participation, as well as increased financial support from governing bodies over the last decade. Thus, there is an onus on researchers and medical departments to develop a better understanding of the physical characteristics and demands, and the health and performance needs of female soccer players. In this review we discuss the current research, as well as the knowledge gaps, of six major topics: physical demands, talent identification, body composition, injury risk and prevention, health, and nutrition. Data on female talent identification are scarce, and future studies need to elucidate the influence of relative age and maturation selection across age groups. Regarding the physical demands, more research is needed on the pattern of high-intensity sprinting during matches and the contribution of soccer-specific movements. Injuries are not uncommon in female soccer players, but targeting intrinsically modifiable factors with injury prevention programmes can reduce injury rates. The anthropometric and physical characteristics of female players are heterogenous and setting specific targets should be discouraged in youth and sub-elite players. Menstrual cycle phase may influence performance and injury risk; however, there are few studies in soccer players. Nutrition plays a critical role for health and performance and ensuring adequate energy intake remains a priority. Despite recent progress, there is considerably less research in female than male soccer players. Many gaps in our understanding of how best to develop and manage the health and performance of female soccer players remain
Interlaboratory Comparison of 25-Hydroxyvitamin D Assays: Vitamin D Standardization Program (VDSP) Intercomparison Study 2 – Part 2 Ligand Binding Assays – Impact of 25 Hydroxyvitamin D2 and 24R,25- Dihydroxyvitamin D3 on Assay Performance
Get PDFThe final publication is available at Springer via http://dx.doi.org/10.1007/s00216-021-03577-0An interlaboratory comparison study was conducted by the Vitamin D Standardization Program (VDSP) to assess the performance of ligand binding assays (Part 2) for the determination of serum total 25-hydroxyvitamin D [25(OH)D]. Fifty single-donor samples were assigned target values for concentrations of 25-hydroxyvitamin D2 [25(OH)D2], 25-hydroxyvitamin D3 [25(OH)D3], 3-epi-25-hydroxyvitamin D3 [3-epi-25(OH)D3], and 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3] using isotope dilution liquid chromatography-tandem mass spectrometry (ID LC-MS/MS). VDSP Intercomparison Study 2 Part 2 includes results from 17 laboratories using 32 ligand binding assays. Assay performance was evaluated using mean % bias compared to the assigned target values and using linear regression analysis of the test assay mean results and the target values. Only 50% of the ligand binding assays achieved the VDSP criterion of mean % bias ≤ |± 5%|. For the 13 unique ligand binding assays evaluated in this study, only 4 assays were consistently within ± 5% mean bias and 4 assays were consistently outside ± 5% mean bias regardless of the laboratory performing the assay. Based on multivariable regression analysis using the concentrations of individual vitamin D metabolites in the 50 single-donor samples, most assays underestimate 25(OH)D2 and several assays (Abbott, bioMérieux, DiaSorin, IDS-EIA, and IDS-iSYS) may have cross-reactivity from 24R,25(OH)2D3. The results of this interlaboratory study represent the most comprehensive comparison of 25(OH)D ligand binding assays published to date and is the only study to assess the impact of 24R,25(OH)2D3 content using results from a reference measurement procedure
